By the way, in the present embodiment, on the counter one weight 5, a rotary motor 10 for driving the counter weight 5 up and down and a motor based on an operation command output from the elevator control device 15 are provided. A control device for controlling 10 is provided with a control device 11, a regenerative resistor 12, a power receiving device 21 for receiving power, and a control device 14, and one of the rollers 9 is connected to the motor 10. It has been done. Further, a power supply device 16 for supplying power to the power receiving device 21 of the counterweight 5 is provided in the hoistway. The power supply device 16 is provided at a position opposite to the position of the counter one weight 5 when the car is stopped at the reference floor (in this embodiment, the lowest floor). When stopped on the floor, power can be supplied to the power receiving device 21.

One of the rollers 9 that comes into contact with the guide rail 8 is connected to a motor 10, and the counter roller 10 rotates to move the counter weight 5 up and down. Car 1 moves up and down with the movement of. Further, the braking device 14 stops the counter weight 5 by narrowing the guide rail 8 when the car 1 stops on the stop floor.

As mentioned above, the regenerative resistor 12 Evening 10, motor control device 11, power receiving device 19, braking device 14, 1 are connected to the motor, and a roller 9 for narrowing the guide rail 8 and a pulley 6 are provided.

Above the counterweight 5, a regenerative resistor 12 is provided, and the motor 10, the motor control device 11, the power receiving device 19, and the braking device 14 are arranged on the counterweight 5 in this order. I have.

The braking device 14 is composed of a driving force portion 141 composed of an electromagnet and a spring, an arm 142, and a braking shoe 144 for pressing the guide rail 8.

FIG. 3 is an electric block diagram of the present embodiment.

The motor control device 11 includes a rectifier circuit 113 for converting alternating current to direct current, a three-phase inverter connected to the DC side of the rectifier circuit 113 for converting direct current to alternating current, and An inverter control circuit 20 for controlling the three-phase inverter is provided. Furthermore, between the rectifier circuit 113 and the inverter 111 (DC side), a battery 117, a filter capacitor 114, and a series of a diode 115 and a regenerative transistor 116 are connected. The bodies are connected in parallel. Note that the inverter control circuit 20 is arranged below the inverter 11. This is because the calorific value of Inver Evening 1 1 1 is larger.

The rotary motor 10 is connected to the AC side of the inverter 11, and the power receiving device 19 is connected to the rectifier circuit 113. This power receiving device 19 has a non-contact transformer 191. The regenerative resistor 12 is connected to the diode 115 in parallel and provided outside the motor control device 11. The power supply device 16 is connected to the three-phase AC power supply 21 and has a non-contact transformer 16 1.

The above non-contact transformer 16 1 and non-contact transformer 19 1 When the vehicle is stopped on the reference floor, that is, when counter 1 weight 5 is at the power receiving position, it faces with a small gap. Between the power supply device 16 and the power receiving device 19, conversion of electric-magnetic energy, transfer of magnetic energy, and reverse conversion of magnetic-electric energy are performed, and power is supplied to the rectifier circuit 113.

This power is supplied to the battery 117 and the capacitor 114 through the rectifier circuit 113. When the terminal voltage of the capacitor 114 drops below a predetermined value when power is not supplied from the power receiving device 19, the notch 1 117 discharges to the capacitor 1 Maintain a DC voltage of 1. The regenerative resistor 12 consumes regenerative energy by turning on the transistor 116 when the motor 10 is in regenerative operation.

The circuit control circuit 20 includes a signal from the current detector 102 of the motor 10 and a signal (encoder pulse) Ep from the rotation detector 101 of the motor 10 and a target floor (to be described later). It takes in the signal Pc indicating the remaining distance and outputs the drive signal Ds to the inverter 111 and the regenerative signal Es to the regenerating transistor 116 to control the rotation speed of the motor 10.

Further, the inverter control circuit 20 outputs the encoder pulse Ep to the elevator controller 15. From the car control device 18, the car detects each floor and detects a floor signal F s indicating the floor on which the car is located, and a target floor signal F c by operation from inside the car. Output to the elevator control device 15. The elevator controller 15 outputs a signal Md indicating the operation mode of the elevator to the car controller 18 and the remaining distance Pc to the target floor to the receiver control circuit.

In addition, the elevator control device 15 outputs a floor signal F s to the call device 17 of each floor, and receives the car call signal C 1 from the call device 17 of each floor. Take away.

With this configuration, the elevator is controlled as follows.

Based on the target floor signal Fc and the floor signal Fs from inside the car, the elevator controller 15 calculates the remaining distance Pc to the target floor, and calculates the remaining distance Pc to the inverter control circuit 20. Output to The inverter control circuit 20 gives a drive signal D s to the inverter 11 and a regenerative signal E s to the regenerating transistor 1 16 to control the motor 10 based on the remaining distance P c.

By the operation of the inverter control circuit 20 as described above, when the motor performs a desired movement, the output pulse Ep of the rotation detector is applied to the elevator controller 15, and the car 1 also operates. The floor signal Fs is updated each time the vehicle passes through each floor on the way. Based on this, the elevator control device 15 changes the remaining distance P c at any time, and eventually, when the remaining distance P c is 0 or enters the range of the allowable positioning error, the car 1 is desired. Arrives and stops at the floor. FIG. 4 is a block diagram of the inverter overnight control circuit 20 shown in FIG.

The pulse signal Ep of the rotation detector 101 of the motor 10 is divided into two, one goes directly to the elevator controller 15 and the other is input to the speed calculation circuit 205 to perform time processing. And converted into a speed signal Ns. The remaining distance signal Pc from the elevator control device 15 to the target floor is input to the speed command generation circuit 201, and a speed command Nc is generated. The speed command Nc is compared with the speed signal Ns, and the speed deviation ΔΝ is input to the current command generation circuit 202, and the current command generation circuit 202 receives the current command based on the speed deviation ΔΝ. Outputs I c.

Note that this current command Ic is the three-phase current of the three-phase The phase may be converted and expressed by replacing the d-axis with the Q-axis, or may be handled as a DC motor with only the d-axis.

The current arithmetic circuit 207 converts the output of the motor current detector 102 into the same dimension as the current command Ic, and outputs it as a current detection value Is.

The voltage command generation circuit 203 inputs the current detection value I s and the current deviation ΔI of the current command I c, generates and outputs a voltage command V c based on the input, and generates a PWM signal. The circuit 204 generates and outputs a PWM signal (pulse width modulation signal) based on the voltage command Vc. Based on this output, the gate of each transistor in the inverter is driven, and a current corresponding to the desired current command Ic flows through the motor 10 and a speed command N corresponding to the remaining distance Pc. c Any operation can be performed.

FIG. 5 is a cross-sectional view of the counter one weight 5 shown in FIG. The center line I of the counter weight 5 and the center line Π of the guide rail 8 are shifted, and the county weight 5 and the guide rail 8 are arranged. In other words, the guide rail 8 is arranged so as to be offset from the vertical center line of the guide rail side surface of the power center wait. With this configuration, it is possible to arrange the motor 10 on the center side of the county 1 weight 5.

(Effect of the first embodiment)

(1) According to the above embodiment, since the counterweight 5 is equipped with the motor 5, the inverter 111, and the inverter control circuit 20, there is no need for a machine room in which these are originally provided. In addition, the weight of these devices is not required, and an extremely high effect can be obtained in terms of space saving and material saving.

(2) Although the output wiring of the inverter 1 1 1 which performs pulse width modulation has the property of generating high-frequency noise, the above-described embodiment has a counter weight of 5%. Since the motor 10 and the antenna 1 11 (motor control device 11) are placed close to each other, the wiring is shortened, and the propagation of high-frequency noise to the building can be suppressed.

(3) In the above embodiment, the inverter 111 and the inverter control circuit 20 are provided on the counterweight 5 and are arranged close to each other. The signal line between the overnight control circuit 20 can be shortened, and noise contamination can be reduced.

(4) If the motor and inverter are mounted on the counter one-way, the power supplied to the counter one-way side will increase. For this reason, if a power supply cable is provided in the evening one day, the cable becomes thicker and heavier.

Attachment of such a cable causes a problem due to cable sway (interference with other devices such as wire damage). In addition, there is a problem with the strength of the cable attachment part to the counterweight.

Also, as the weight of the cable increases, the load (at startup) of the motor driving the counterweight increases, and the motor and inverter mounted on the counterweight also increase in size.

In this embodiment, the power is supplied to the county 1 wait 5 in a non-contact manner by the power receiving device 19 and the power feeding device 16, thereby eliminating the need for a power supply cable (or providing only a signal transmission cable). Good thing) and can solve the above problem.

(5) Further, in the above embodiment, a roller connected to the rotary motor is provided on the county one weight 5, and the guide rail is narrowed by this roller to drive the counter one weight up and down. are doing. Therefore, since the driving force of the motor is directly transmitted to the vertical movement of the counter weight, it is necessary to drive the pulley provided on the counter weight with the motor. In comparison, the driving force of the motor is small.

In addition, since the existing guide rail is used to drive the counter one way up and down, there is no need to provide a new mechanism to drive the counter one way up and down.

In addition, since the drive roller is located above the counter one way, that is, the motor is located above, the noise and wear are reduced as compared to the drive roller below. it can. When the drive roller is provided on the lower side, the counterweight is easily mechanically shaken, which causes noise and wear problems.

(6) In the above embodiment, the counterweight 5 includes the regenerative resistor 12, the motor 10, the motor control device 11, the power receiving device 19, and the braking device from above.

They are arranged in the order of 14. With such an arrangement, a regenerative resistor such as a regenerative resistor, which generates a large amount of heat, can be placed at the top to minimize the effect of heat on other devices.

Furthermore, comparing the heat generation in detail, in addition to the regenerative resistor, the motor also generates heat due to losses such as copper loss and iron loss. In addition, even in the case of a transient in the motor control device, a loss occurs and heat is generated, and the braking device is also composed of an electromagnet and a panel. However, among them, the regenerative resistor consumes almost all of the regenerative energy, so its heat generation is large, followed by the motor and the motor controller. Therefore, it is appropriate to arrange the regenerative resistor, then the motor, and the motor controller in this order at the top as described above. Also, the arrangement of the inverter 111 and the inverter control circuit 20 in the motor controller is such that the inverter 111, which generates a large amount of heat, is disposed above the inverter control circuit 20. ing.

(7) Further, in the above embodiment, the power supply device 16 is arranged to face the position of the counterweight 5 when the car 1 is stopped on the reference floor, Power can be supplied when car 1 is located on the reference floor (the lowest floor in the figure). With such an arrangement, the probability that the power supply device and the power receiving device match will be increased, and power supply can be performed easily.

(8) According to the above embodiment, the center line of the counter one weight 5 and the center line of the guide rail 8 are shifted, and the counter weight 5 and the guide rail 8 are arranged.

With such a configuration, the motor 10 can be arranged at the center side of the counter weight 5 and the thickness of one counter weight (in the horizontal direction in the figure) can be reduced, thereby improving space efficiency. .

Next, a second embodiment will be described with reference to FIG.

Next, another embodiment of the county and one weight according to the present invention will be described.

FIG. 6 is a diagram showing a counterweight according to another embodiment of the present invention.

Fig. 6 (a) is a top view, Fig. 6 (b) is a plan view, and Fig. 6 (c) is a side view.

In this embodiment, the device mounted on the coun- ty and one weight is not limited to the motor 10 and the motor control device 11, the braking device 14 and the regenerative resistor 12. This is an example in which the device is stored in a counterweight. Also in the present embodiment, the county weight 5 is driven up and down by the guide rail narrow pressure drive of the roller 9. In this figure, the pulley 6 for suspending the counter weight 5 and the braking device 14 are omitted.

The roller 9 rolls along the guide rail 8 of the counterweight. One of these rollers 9 is driven by motor. Mouth-Bully 2 2 directly connected to the shaft of La 9 and Pulley directly connected to 10 Ri 24 is prospered through belt 23. The bully 22 has a larger diameter than the bully 24, and the circumference ratio between the two is the reduction ratio, which serves as a reduction mechanism. The reduction mechanism is composed of a pulley 22, a pulley 24, and a belt 23.

In the present embodiment, the motor 10 and the roller 9 (one of them) are not directly connected, but are indirectly connected via a belt. As shown, the clock 10 can be arranged at the center of the counter weight 5 in the thickness direction.

(Effect of the second embodiment)

(1) According to the above embodiment, a mechanism for transmitting the driving force of the motor 10 to the (one) roller 9 via the belt through the belt provides a degree of freedom in the arrangement of the motor. The motor 5 can be arranged at the center position in the thickness direction of the county weight 5. Therefore, the weight of the evening can be reduced, and the hoistway can be used effectively as an evening.

(2) According to the above-described embodiment, the provision of the speed reduction mechanism allows the motor to be small and low-cost.

As is apparent to those skilled in the art, the size of the motor is determined not by power but by torque, so that a motor with a high rotation speed and a small torque can reduce the size. Therefore, when the speed reducer as in the embodiment is provided, the size of the motor to be used can be reduced. Normally, when a direct drive module is placed on the day and day of the country, the volume of the module cannot be reduced, so that the module must be made thinner and thinner. However, such a special motor has a problem that the cost increases. If the size of the mobile phone is small as in the embodiment, the general-purpose mobile phone can be used instead of the special mobile phone, so the overall system cost can be reduced. You.

In general, when a motor with the same output is downsized by lowering the torque and increasing the rotation speed, a problem of heat generation occurs. However, in the present embodiment, the motor is moving on the counterweight during its operation, and there is always an air flow around the motor, which is advantageous from the viewpoint of cooling. Needless to say, the above effects can be realized not only by the belt reducer but also by a worm gear made of metal or the like.

(3) According to the present embodiment, since a belt is used for the speed reducer, noise can be prevented and the reliability of the motor can be improved.

In particular, noise is a major problem in elevator systems that install motors in hoistways. Therefore, in this embodiment, a belt is used. Due to recent improvements in material technology, there are many easy-to-handle and durable belts made of fiber for the timing belts of automobiles and the ropes of hoists of cranes. In this embodiment, such a material is used. Therefore, there is no noise due to metal-metal contact, so there is no noise source like a gear. Also, in the case of a metal gear, abrasion of the teeth generates metal powder, which adheres to the motor coil portion, the bearing, or the circuit of the control device, and there is a concern that the gear may be completely destroyed. Since the belt according to the embodiment does not contain metal powder, there is no such concern, and there is an advantage that the reliability of the motor is improved.

Next, a third embodiment will be described with reference to FIGS. 7 and 8. FIG.

FIG. 8 is a diagram showing the overall configuration of the third embodiment according to the present invention. In the present embodiment, a traction section 25 is provided at the counter weight, and this sif 25 is mounted on the counter weight 5 at a flat type motor 27 (perpendicular to the rotation plane of the motor). Motor with a small thickness in the direction) to drive counter gate 5 up and down. The mouthpiece 3 suspends the traction sheave 25 above the counterweight 5. The traction sheave 25 of the counter weight 5 rotates integrally with the larger diameter pulley 26, and the pulley 26 is connected to a flat motor 27 and a pulley 28 directly connected to the shaft via a belt 29. They are connected. The counterweight 5 is provided with the motor control device 11 and the regenerative resistor 12 as in the first and second embodiments.

In this embodiment, as described in the second embodiment, the pulley 26, the pulley 28, and the belt 29 constitute a reduction mechanism, and the circumference ratio of the pulley 26 and the pulley 28 is similar to that of the second embodiment. Is the reduction ratio. Also, since the counterweight 5 is lifted from above, the traction sheave 25 is located above the motor so that the rope does not have to be pulled around. It is preventing from becoming. Further, in the present embodiment, since the drive is generated at the suspended point (sheave 25), it is more stable to dispose the sheave 25 above the county wait 5. Also, naturally (to more easily transmit the driving force), the flat motor 27 is disposed immediately below the sheave 25. Therefore, the motor control device 11 is disposed below the flat type motor 27.

FIG. 8 is a detailed diagram of the counter one weight 5 shown in FIG.

Since the braking device 30 is a safety device, it is provided on the sheave 25 side, not on the flat type motor 27 side. Therefore, even if the belt 29 breaks, the brakes of the elevator operate normally. In addition, the belt 29 is installed on the car 1 side, not on the hoistway wall side, so that it can be easily replaced on a regular basis. it can.

(Effect of the third embodiment) (1) In the present embodiment, since the driven sheave 25 is disposed above the county one weight 5, interference in the rope 3 counterweight can be prevented, and the counter one weight can be stabilized. Good nature. In addition, since the motor 27 is disposed immediately below, the driving force of the motor 27 can be transmitted to the sheave 25 with a simpler configuration.

(2) According to the above embodiment, since the motor 27 and the belt speed reduction mechanism are mounted on the counter weight 5, the same effects as (2) and (3) of the above second embodiment can be obtained. Can be.

(3) According to the present embodiment, since the belt 29 is provided on the car 1 side, not on the hoistway wall side, the operator can directly replace the belt 29 with the car 1 from the car 1, Belt replacement work becomes easy.

Next, a fourth embodiment will be described with reference to FIGS. 9 and 10. FIG. FIG. 9 is a perspective view of a counterweight according to a fourth embodiment of the present invention.

In the present embodiment, the motor itself is housed in the sheave 6, and is a built-in motor type.

Therefore, as shown in FIG. 9, there is no motor between the regenerative resistor 12 and the motor controller 12.

The details of this embodiment will be described with reference to FIG.

FIG. 10 (1) is a front view, and FIG. 10 (2) is a cross-sectional view. The sheave 6 has a hollow inside and a motor 100 incorporated therein. The motor 100 consists of a permanent magnet 101, a stator 102, a coil 103, a fixed bearing 104, a shaft 105, and a beam 106. A permanent magnet 101 is provided on the inner periphery of the sheave 6, and a stator 102 having a coil 103 wound around it is fixed to a fixed shaft 105. Sheave 6 Bearlin The fixed shaft 105 is rotatably supported by the bush 104, and the fixed shaft 105 is fixed to the beam 106. In addition, a regenerative resistor 1 2 is disposed below the sheave 6 so as to be covered with a cover 1 2 1.

According to the present embodiment, the drive system can be simplified since the drive 6 is directly driven by the motor 100 disposed therein. In other words, the space for the counterweight can be saved.

In this embodiment, a roller is used for the guide device of the counterweight. However, since the roller is not used as a driving unit, a guide show may be used.

Next, a fifth embodiment will be described with reference to FIGS. 11 and 12. FIG. FIG. 11 is a perspective view of a countdown weight according to a fifth embodiment of the present invention.

In the present embodiment, the motor 111 and the sheave 6 are connected via a gear 124 to drive the sheave 6. In this embodiment, as shown in FIG. 11, the rotating surface of the motor 111 is perpendicular to the moving direction of the counterweight 5, and the rotation of the motor 111 The transmission is transmitted to the sheave 6 via the gear 108.

Details of the present embodiment will be described with reference to FIG.

FIG. 9 (1) is a front view, and FIG. 9 (2) is a cross-sectional view.

The output shaft of the motor 111 is connected to the gear 125, which is geared with the gear 124. The gear 124 is directly connected to the sheave 6 and is fixed by a beam 122 through a bearing 122. When the motor 1 1 1 1 rotates, the gears 1 2 5 and 1 2 4 rotate, and the sheave 6 moves the gear 1 2 0 5 and the gear 1 2 0 with respect to the motor 1 1 1. Decelerates and rotates at the ratio of 4 teeth. According to the present embodiment, by arranging the motor so that the rotation axis is orthogonal to the sheave, the layout of the motor can be easily performed. In addition, since the motor torque is reduced by the reduction ratio, the dimensions of the motor can be reduced, and installation on the counter weight becomes easier.

In this embodiment, the gears are exposed, but the gears may be put in a box in order to prevent dust and prevent the lubricating oil from scattering. The bevel gear is a bevel gear, but it is possible to obtain similar effects by using various gears such as a worm gear.

Next, a sixth embodiment will be described with reference to FIGS. 11 and 12. FIG. FIG. 13 is a diagram showing the vicinity of one counter in the sixth embodiment. In the first embodiment shown in FIG. 1, power is not supplied to the county one-way, and signal transmission to the counterweight is performed by wire. In the present embodiment, a power supply trolley line 1301 and a signal trolley line 1302 are laid (along the hoistway) on the hoistway wall behind the counterweight 5. Then, electric power and information (signal) are supplied to the counter 1 side 5 via the trolley line 1301 and 1302.

The details of this embodiment will be described with reference to FIG.

The power supply trolley line 1 301 and the signal trolley line 1 302 are laid on the shaft wall by a bracket 133. The power supply trolley line 1301 and the power supply device 1307 are connected by a power supply cable 1309, and the signal trolley wire 1320 and the signal device 1306 are connected by a signal cable 13 08 It has been. A power receiving device 1304 and a signal input / output device 135 are provided in the counter one way 5 indicated by the dotted line, and power and signals are transmitted and received from the trolley in contact with the trolley wire.

According to the present embodiment, there is no need to use a tail code, and the counter Since it is not necessary to consider the interference between the tail cord and other equipment that vibrates due to the movement of the eight, the equipment arrangement in the hoistway becomes easier. In the case of non-contact power supply, it is difficult to supply power at all times, so a battery is required. However, in the case of a single trolley power supply as in this embodiment, a battery can be unnecessary.

Next, a seventh embodiment will be described with reference to FIG.
