Description

  The present invention relates to a bicycle parking apparatus installed in, for example, a housing complex or a bicycle parking lot of a station, and more particularly, to a bicycle parking apparatus provided with an elevating member for lifting and storing a bicycle.

  In the case of this type of bicycle parking device, the bicycle can be stored in multiple stages using the storage space formed under the bicycle that is lifted and stored by the elevating member, and many bicycles can be stored effectively using the storage space. There is an advantage that can be stored. In the case of such a bicycle parking device, a drive source for raising and lowering the elevating member is essential.

  In this type of bicycle parking apparatus, there is a conventionally known one that stores a slider as an elevating member in a state in which the bicycle is raised by urging and energizing the slider by an urging force of a spring (for example, Patent Document 1). ). In addition, there is a device that stores a mounting table as an elevating member in a state in which the bicycle is raised by being urged upward by the urging force of a fluid damper (gas spring) (for example, Patent Document 2). Furthermore, there has been one that stores a rack as an elevating member in a state in which the rack is lifted by a biasing force of an air cylinder and the bicycle is lifted (for example, Patent Document 3).

JP 2012-21266 A JP 2002-4619 A JP2015-117541A

  In the case of the ones described in Patent Document 1 and Patent Document 2, there is a risk that the elevating member that is lifted and biased by the biasing force of the spring or the fluid damper (gas spring) may unexpectedly spring up. Moreover, in the case of patent document 3, there exists a fault that the problem of a noisy noise arises when the air in an air cylinder is discharge | released and the raising / lowering member is lowered | hung, and the sound in which air is discharged | emitted is produced.

  The present invention has been conceived in view of such circumstances, and an object of the present invention is to provide a bicycle parking apparatus that is safe and does not cause noise problems.

A bicycle parking apparatus according to an aspect of the present invention is a bicycle parking apparatus including a lifting member (for example, a slider 8 and a rack 6) for lifting and storing a bicycle,
A motor as a drive source for raising and lowering the elevating member;
Safety means (for example, S2) for avoiding the danger associated with the raising and lowering of the elevating member,
The safety means is in a stationary state in which the lifting member does not move in the first direction when the moving load deviates from the normal range when the lifting member is moving in the first direction (for example, S33, S41). , S42, S34, S43, S44, S47 and S48, or the torque limiter 48).

  According to such a configuration, since the motor is used as a drive source for raising and lowering the elevating member, noise can be prevented as much as possible, and the danger of the elevating member jumping unexpectedly can be avoided as much as possible. In addition, when the moving load deviates from the normal range when the elevating member is moving in the first direction, the elevating member is in a stationary state in which it does not move in the first direction, so safety can be ensured.

  Preferably, the safety means makes the stationary state by stopping the motor (for example, S47).

  According to such a configuration, it is possible to prevent inconvenience that the motor is driven wastefully during the stationary state.

Preferably, it further includes a human detection means (for example, human sensor 14) capable of detecting a person,
The safety means is set to the stationary state when the person detecting means capable of detecting a person detects a person entering the dangerous area (for example, S32, S39, S40, S47).

  According to such a configuration, when a person enters the dangerous area, it becomes stationary and further safety can be secured.

Preferably, an operation means (for example, a button switch 7) capable of an operation for raising and lowering the elevating member and an operation for lowering is further provided.
The safety means disables the operation by the operation means when the person detection means detects a person who has entered the danger area (for example, when YES in S32, the process enters a reset waiting state in S48 and the determination in S6) Is not done).

  According to such a configuration, when it is detected that a person has entered the dangerous area, the operation for raising and lowering the elevating member is disabled and further safety can be secured. .

Preferably, the apparatus further comprises obstacle detection means (for example, an obstacle detection plate 50 and an obstacle sensor 51) for detecting an obstacle that becomes an obstacle to the elevating member that descends.
The safety means sets the stationary state when the obstacle detection means detects an obstacle (for example, S35, S45 to S47).

  According to such a structure, since it will be in a stationary state when the obstruction which becomes an obstacle of the raising / lowering member to fall is detected, the further safety | security can be ensured.

It is a figure which shows the principal part of the modification 2.

  Hereinafter, the present embodiment will be described in detail with reference to the drawings. A bicycle parking apparatus according to an embodiment of the present invention is shown in FIG. The bicycle parking lot is provided with a plurality of bicycle parking devices, one of which is shown in FIG. This bicycle parking apparatus includes a support column 2 extending in a vertical direction, a screw shaft 3 provided in the support column 2, a motor 1 as a drive source for rotating the screw shaft 3 around its axis, The drive pulley 4 and the driven pulley 5 for transmitting the rotational driving force of the motor 1 to the screw shaft 3, the belt 10 for transmitting the rotational force from the driving pulley 4 to the driven pulley 5, and the screw shaft 3 are screwed together. As a result of the rotation of the screw shaft 3, the screwed portion 11 that moves up and down along the column 2, the slider 8 that moves up and down integrally with the screwed portion 11, and the slider 8 are connected in a cantilevered manner. And a rack 6 extending in the front-rear direction.

  A state in which the bicycle owner puts the bicycle 9 on the mounting table 49 of the rack 6 while the rack 6 is lowered is shown by a solid line in FIG. In this state, when the owner of the bicycle operates the button switch 7 provided on the front end side of the mounting table 49 (for example, when stepping with a foot), the motor 1 rotates in the forward direction and the rotational force is increased to the driving pulley 4 and the belt. 10, transmitted to the screw shaft 3 via the driven pulley 5. A screwing portion 11 is screwed to the screw shaft 3, and the slider 8 described above is attached to the screwing portion 11. Then, the screw shaft 3 is rotated forward along with the normal rotation of the motor 1, whereby the screwing portion 11 is pushed upward together with the slider 8. As a result, the rack 6 rises with the slider 8 and the bicycle 9 on the mounting table 49 also rises. The raised state is indicated by a two-dot chain line in FIG.

  Inside the column 2, an upper limit switch 12 and a lower limit switch 13 are provided. With the rack 6 raised to a predetermined upper limit position, the screwing portion 11 contacts the actuator of the upper limit switch 12 and the upper limit switch 12 is turned on. When the upper limit switch 12 is turned on, the motor 1 is controlled to stop. As a result, the raising of the rack 6 stops.

  When the owner of the bicycle 9 presses the button switch 7 while the rack 6 is stopped at the upper limit position, the motor 1 is reversed and the screw shaft 3 is reversed. As a result, the screwing portion 11 is lowered and the slider 8 and the rack 6 are lowered. When the rack 6 is lowered to the lower limit position, the screwing portion 11 comes into contact with the actuator of the lower limit switch 13, and the lower limit switch 13 is turned on. When the lower limit switch 13 is turned on, the motor 1 is stopped and the rack 6 is stopped at the lower limit position.

  A human sensor 14 is provided on the ceiling surface 15 of the bicycle parking lot. The human sensor 14 is for detecting that a human has entered a dangerous area. For example, when a human enters a region where the rack 6 moves up and down, the human sensor 14 detects the person and enters the motor. 1 is stopped. Thereby, the danger that the person who entered the danger area touches the rack 6 etc. and is injured can be avoided, and safety can be secured.

  The failure detection plate 50 is pivotally supported by the pivot shaft 52 on the base end side (the column 2 side) of the mounting table 49. Further, on the front end side of the mounting table 49, the mounting table 49 and the failure detection plate 50 are connected by an elastic member 53. The elastic member 53 is made of, for example, a coil spring or rubber. A fault sensor 51 is provided on the front end side of the fault detection plate 50. While the rack 6 is descending, there are some obstacles (including humans) below the rack 6, and when the obstacle sensing plate 50 comes into contact with the obstacles, the elastic member 53 is pressed and contracted, and the obstacle sensor 51 is turned ON. When the failure sensor 51 is turned on, the motor 1 is controlled to stop. As a result, it is possible to avoid the danger that a person will underlay the rack 6 or the like, and to ensure safety.

  An overload detection mechanism 17 is provided in the upper part of the support column 2. When the load increases while the rack 6 is moving up or down and the motor 1 is overloaded, the overload detection mechanism 17 is activated to stop the motor 1. Details of the overload detection mechanism 17 will be described later. In FIG. 1, reference numeral 56 denotes a speaker that notifies the owner of the bicycle 9 of various messages by voice. Reference numeral 16 in FIG. 1 denotes a control unit that performs drive control and safety control of the bicycle parking device. In FIG. 1, 13a is a bearing. In FIG. 1, reference numeral 18 denotes a cover, which is detachably attached to the plate 19. For example, when an abnormal situation occurs in which the bicycle 9 placed on the rack 6 is stopped halfway due to a failure or the like, the cover 18 is removed and a crank handle is attached to the handle shaft 35 to manually By rotating the screw shaft 3, the rack 6 is lowered and the bicycle 9 can be lowered from the mounting table 49.

  Next, details of the above-described overload detection mechanism 17 will be described with reference to FIG. The housing 20 of the overload detection mechanism 17 is attached to the plate 19 with screws 21a and 21b. A cylindrical sprung holding cylinder 23 and unsprung holding cylinder 22 are built in the housing 20. Coiled springs 28 are accommodated in the holding cylinders 22 and 23. Insertion holes for inserting the screw shaft 3 are formed in the bottom portions of the holding cylinders 22 and 23, respectively. An upper bearing 30 and a lower bearing 29 are provided for rotatably holding the screw shaft 3 inserted through the insertion hole. The upper bearing 30 is provided with an upper small retaining ring 33 and an upper large retaining ring 34. On the other hand, the lower bearing 29 is provided with a lower small retaining ring 31 and a lower large retaining ring 32. A lower portion of the screw shaft 3 is pivotally supported by a bearing 13a. The screw shaft 3 is pivotally supported so as to be slidable in the vertical direction with respect to the bearing 13a.

  In this state, when a downward force is applied to the screw shaft 3, the force is transmitted to the spring 28 via the upper small retaining ring 33, the upper bearing 30, and the sprung holding cylinder 23. As a result, the screw shaft 3, the upper small retaining ring 33, the upper bearing 30, and the sprung holding cylinder 23 are pushed down against the repulsive force of the spring 28. Conversely, when an upward force is applied to the screw shaft 3, the force is transmitted to the spring 28 via the lower small retaining ring 31, the lower bearing 29, and the unsprung holding cylinder 22. As a result, the screw shaft 3, the lower retaining ring 31, the lower bearing 29, and the unsprung holding cylinder 22 are pushed up.

  A switch cover 21 is provided in the housing 20, and an upper limit switch 25 and a lower limit switch 24 are provided in the switch cover 21. When the sprung holding cylinder 23 moves downward, the upper actuator 27 of the upper limit switch 25 is pressed by the sprung holding cylinder 23 and the upper limit switch 25 is turned on. On the other hand, when the unsprung holding cylinder 22 moves upward, the actuator 26 of the lower limit switch 24 is pressed by the unsprung holding cylinder 22 and is turned ON. By appropriately adjusting the repulsive force of the spring 28, the relative maintenance relationship between the sprung holding cylinder 23 and the upper limit switch 25, and the relative positional relationship between the unsprung holding cylinder 22 and the lower limit switch 24, the screw shaft The lower limit switch 24 is turned on at the moment when an upward force exceeding the allowable range is applied to 3 and the upper limit switch 25 is turned on at the moment when the downward force exceeding the allowable range is applied to the screw shaft 3. It is configured. Then, at the moment when the upper limit switch 25 or the lower limit switch 24 is turned ON, the motor 1 is controlled to stop by the action of the control unit 16. By controlling in this way, the motor 1 is stopped and the movement of the rack 6 is stopped at the moment when an abnormal state with an overload is applied, and safety can be ensured.

  Next, the structure of the slider 8 and its periphery will be described with reference to FIG. Fig.3 (a) is the figure which showed the AA cross section of FIG.3 (b). A fitting projection 38 is formed in the screwing portion 11 screwed into the screw shaft 3. On the other hand, the slider 8 is formed with a fitting recess 39 into which the fitting protrusion 38 is inserted. A fitting protrusion 38 is inserted into the fitting recess 39.

  The slider 8 has an H-shaped cross section, and rollers 37 are provided at the four corners on the left and right and the top and bottom. The guide rail 36 is sandwiched between the rollers 37. As a result, when the screw shaft 3 rotates, the screwing portion 11 moves up and down, and the slider 8 moves up and down along the guide rail 36 accordingly.

  Further, a gap is formed between the front end side of the fitting protrusion 38 of the screwing portion 11 and the bottom side of the fitting concave portion 39, and play is formed between them. Since the screw shaft 3 has a certain length, it is not necessarily formed in a complete straight line, and may have a bent shape. The bending dimension is absorbed by this gap, and the slider 8 is configured to move up and down smoothly. Note that a slight gap may be formed between the fitting projection 38 and the fitting recess 39 in the vertical direction to create play.

  Next, the block diagram of the control part 16 and the management server 55 is demonstrated based on FIG. The bicycle parking lot is provided with a wireless local area network (LAN) router 76. A management server 55 is installed in the management center 54 that manages the bicycle parking lot. Each control unit 16 provided in the bicycle parking apparatus is configured to be able to wirelessly communicate with the management server 55 of the management center 54 via the wireless LAN router 76.

  The control unit 16 is provided with a microcomputer 60 and a communication unit 65, which can communicate with the management server 55 via the wireless LAN router 76 as described above. . The microcomputer 60 includes a ROM (Read Only Memory) 61 that stores a control program and control data, a CPU (Central Processing Unit) 63 as a control center that performs control operations according to the control program, and a work of the CPU 63. A RAM (Random Access Memory) 62 functioning as an area and an I / O port 64 for inputting and outputting signals with the outside are provided. Furthermore, the control unit 16 includes a motor circuit 57, a switch circuit 58, and a speaker circuit 59.

  When the motor control signal from the microcomputer 60 is input to the motor circuit 57, the motor 1 is driven and controlled. Detection signals from the button switch 7, the upper limit switch 12, the lower limit switch 13, the human sensor 14, the lower limit switch 24, the upper limit switch 25, the failure sensor 51 and the reset switch 75 are sent to the microcomputer via the switch circuit 58. Is input. The reset switch 75 is a switch that is operated after the clerk repairs the error state when an error occurs in the bicycle parking device and the control by the control unit 16 is stopped, and the reset switch 75 is operated. By doing so, the control of the stopped control unit 16 is resumed. When the microcomputer 60 outputs a speaker control signal to the speaker circuit 59, sound is emitted from the speaker 56.

  The management server 55 includes storage means such as a CPU 72, RAM 71, ROM 73, HDD (hard disk drive) 74, input operation unit 68 such as a keyboard, communication unit 66, display unit 67, interface 69, bus 70, and other various hardware. Consists of.

  Next, control operations of the microcomputer 60 and the management server 55 will be described with reference to FIGS. FIG. 5A is a flowchart showing a main routine program of the microcomputer 60. In step (hereinafter simply referred to as “S”) 1, drive control processing for driving and controlling the bicycle parking apparatus is performed, and in S 2, safety control processing for safely controlling the operation of the bicycle parking apparatus is performed and controlled. Returns to S1.

  FIG. 5B is a flowchart showing a subroutine program of the drive control process shown in S1 described above. In S5, it is determined whether or not the button operation flag is ON. If not, it is determined whether or not there is a button switch operation. If not, the drive control process returns. As a result, the above-described safety control process of S2 is executed.

  On the other hand, when the button switch 7 is operated, YES is determined in S6, the control proceeds to S8, and control for turning on the button operation flag is performed. In S9, it is determined whether or not the upper position flag is ON. This upper position flag is set to ON when the rack 6 is in the raised position, and is set to OFF when the rack 6 is in the lower position. When the rack 6 is in the lower position, it is determined NO in S9, the control proceeds to S10, and a process for setting the rising timer is performed. This rise timer is a timer for determining whether or not the rack 6 at the lower limit position has been raised to the upper limit position within a predetermined time. A time slightly longer than the time required for the rack 6 in the lower limit position to normally rise and reach its upper limit position is set in this increase timer.

  Next, in S11, the motor 1 is controlled to rotate forward, and in S12, it is determined whether or not the upper limit switch is turned on. The upper limit switch 12 is turned on when the rack 6 is raised to the upper limit position (see FIG. 1), but if the upper limit switch 12 is not yet turned on, the control proceeds to S13. It is determined whether the rising timer has expired. If the time-up timer set in S10 has not yet expired, a determination of NO is made in S13, the drive control process returns, and the control shifts to S2.

  At the stage where S1 is executed after S2 is executed, the button operation flag is set to ON in S8 described above and the rising timer is set by S10, so both S5 and S7 are determined to be YES. Then, the control proceeds to S11, and the forward rotation control of the motor 1 is continued. The loop of S5 → S7 → S11 → S12 → S13 → S2 → S5 is repeatedly executed for a while when the rack 6 rises.

  If the upper limit switch 12 is turned on before the time-up timer expires, S12 is determined as YES, the control proceeds to S14, the motor 1 is stopped, the button operation flag is turned off, the time-up timer is cleared, Control to turn on the upper position flag is performed. Thereby, the further raising of the rack 6 is stopped.

  On the other hand, if the rack 6 has not reached the upper limit position even after the elapse of the predetermined time counted by the ascending timer, S13 is determined as YES, the control proceeds to S15, and an ascendable error is set. . This is a state in which an abnormality has occurred in which the rack 6 does not reach the upper limit position even though an appropriate time necessary for the rack 6 to move from the lower limit position to the upper limit position has elapsed. An ascendable error is set to. You may alert | report that the abnormality generate | occur | produced when the rack 6 raises with the process of S15 with the speaker 56. FIG.

  Next, a case where the rack 6 is in the raised position will be described. In this case, since the upper position flag is ON (see S14), the button switch 7 is operated, YES is determined by S6, the process of S8 is executed, and after YES is determined by S9, the control is performed. Proceed to S16. In S16, a process for setting a descent timer is performed. This descent timer is a timer for determining whether or not the rack 6 at the upper limit position has lowered to the lower limit position within a predetermined time. A time slightly longer than the time required for the rack 6 in the upper limit position to descend normally and reach the lower limit position is set in this descent timer.

  Next, the control to reversely rotate the motor 1 is performed in S17, and it is determined in S18 whether or not the lower limit switch is turned on. The lower limit switch 13 is turned ON when the rack 6 is lowered and reaches its lower limit position (see FIG. 1), but if the lower limit switch 13 is not yet ON, the control proceeds to S20. It is determined whether the descent timer has timed out. If the descent timer set in S16 has not yet timed out, it is determined NO in S20, the drive control process returns, and the control shifts to S2.

  At the stage where S1 is executed after S2 is executed, the button operation flag is set to ON in S8 and the rising timer is cleared in S14, so that YES is determined in S5 and NO in S7. After the determination, the control proceeds to S17, and the reverse rotation control of the motor 1 is continued. While the rack 6 is lowered, the loop of S5 → S7 → S17 → S18 → S20 → S2 → S5 is repeatedly executed.

  If the lower limit switch 13 is turned on before the descent timer expires, S18 is determined as YES and the control advances to S19, the motor 1 is stopped, the button operation flag is turned off, the descent timer is cleared, Control to turn off the upper position flag is performed. As a result, further lowering of the rack 6 is stopped.

  On the other hand, if the rack 6 has not reached its lower limit position even though the predetermined time counted by the descent timer has elapsed, the determination at S20 is YES, the control proceeds to S21, and the descent impossible error is set. . This is a state in which an abnormality has occurred in which the rack 6 does not reach the lower limit position even though an appropriate time required for the rack 6 to move from the upper limit position to the lower limit position has elapsed. A descent impossible error is set in. You may alert | report that the abnormality generate | occur | produced when the rack 6 descend | falls with the process of S21 with the speaker 56. FIG.

  Next, a flowchart of the subroutine program for the safety control process shown in S2 will be described with reference to FIG. In S30, it is determined whether or not the error flag that cannot be raised is ON. If not, it is determined whether or not the error flag that cannot be lowered is turned ON in S31. It is determined whether or not the sensor is ON. If not, it is determined in S33 whether or not the upper limit switch is ON. If not, the lower limit switch is turned ON in S34. If not, it is determined in S35 whether or not the failure sensor is ON. If not, it is determined whether or not there is an ON error flag in S36. This safety control process returns. As a result, the control returns to S1.

  While the steps of S30 to S36 are being repeatedly executed, when the ascendable error due to S15 is set, it is determined as YES by S30, and the control proceeds to S37, and the ascendable error together with the ID of the bicycle parking device is displayed. It is transmitted to the management server 55. The communication unit 65 of each control unit 16 stores an ID assigned to the bicycle parking apparatus provided with the control unit 16, and transmits the ID to the management server 55. Further, when the descent impossible error is set in S21, YES is determined in S31 and the process proceeds to control S38, and the descent impossible error is transmitted to the management server 55 together with the ID of the bicycle parking apparatus. If a person enters the danger area where the rack 6 moves up and down and is detected by the human sensor 14, the determination at S32 is YES and the control proceeds to S39. 55. In step S40, the human error flag is turned ON.

  If the upper limit switch 25 is turned ON, it is determined as YES by S33, and the control advances to S41, and the rising overload error is transmitted to the management server 55 together with the ID of the bicycle parking apparatus. Next, the rising overload error flag is turned ON by S42. If the lower limit switch 24 is turned ON, it is determined as YES by S34 and the control advances to S43, and a descent overload error is transmitted to the management server 55 together with the ID of the bicycle parking apparatus. Next, the descent overload error flag is turned ON by S44. If the failure sensor 51 is turned on, it is determined as YES by S35 and the control advances to S45, and a failure error is transmitted to the management server 55 together with the ID of the bicycle parking device. Next, the failure error flag is turned ON by S46.

  After the step S37, S38, S40, S42, S44 or S46 is executed, the control proceeds to S47, and the motor 1 is controlled to stop. Thereby, the rack 6 stops when the rack 6 is moving up and down. Next, the control advances to S48, where it is determined whether or not a reset operation has been performed, and waits until there is. In this state, a bicycle parking attendant goes to the bicycle parking device where the abnormality has occurred and repairs and repairs the abnormal state. By operating the reset switch 75, it is determined YES in S48, the control proceeds to S49, and is in the ON state. The process of turning off the error flag is performed. In this way, if any error state occurs, a reset wait state is entered in S48, and no other control is executed. As a result, even if the button switch 7 is operated in the reset waiting state, the operation is ignored and the rack 6 does not move up and down. Further, there is a case where the microcomputer 60 resumes the control of the first step S1 when a power failure occurs during the reset waiting state and the power failure is restored. In that case, when the control reaches S36, it is determined that there is an ON state error flag, the control proceeds to S48, and again enters the reset wait state.

  The management server 55 determines whether or not there is a reception from the control unit 16 in S55. If any error flag is transmitted, it is determined as YES in S55 and the control advances to S56, and the error flag of the ON state is determined. Control for displaying both the error message corresponding to the type and the received ID on the display unit 67 is performed. An attendant who sees the error message corresponding to the type of error goes to the bicycle parking device corresponding to the displayed ID, repairs and repairs the abnormality, and operates the reset switch 75. As a result, it is determined as YES in S48, and the process exits the reset waiting state.

  Next, FIG. 7 will be described based on FIG. Differences from the main embodiment shown in FIGS. 1 to 6 will be mainly described. In the first modification shown in FIG. 7, the slider 8 and the rack 6 are moved up and down by the belt 44. One end of the belt 44 is attached to the plate 19 and the other end of the belt 44 is attached to the slider 8. The intermediate portion of the belt 44 is stretched over two pulleys 42 and 43. The threaded portion 11 that is threadedly engaged with the screw shaft 3 below the overload detection mechanism 17 is provided with a retractable cylinder 40 that extends downward. A pulley support rod 41 is provided at the tip of the retractable cylinder 40, and a pulley 42 is provided at the tip of the pulley support rod 41.

  As in the main embodiment, the driving force of the motor 1 is transmitted to the driven pulley 5 and the screw shaft 3 that rotates integrally with the driven pulley 5 rotates. As the motor 1 rotates forward, the screw shaft 3 rotates in the normal direction, so that the screwing portion 11, the retractable cylinder 40, and the pulley 42 are lowered. Accordingly, the slider 8 and the rack 6 are lifted by the belt 44. On the contrary, when the screw shaft 3 is reversely rotated with the reverse rotation of the motor 1, the screwing portion 11, the retractable cylinder 40 and the pulley 42 are raised. Along with this, the belt 44 is loosened, and the slider 8 and the rack 6 are lowered. When the slider 8 and the rack 6 reach the upper limit position, the upper limit switch 12 comes into contact with the slider 8 and becomes ON, and the motor 1 is controlled to stop. When the slider 8 and the rack 6 reach the lower limit position, the lower limit switch 13 Is in contact with the slider 8 and is turned on, and the motor 1 is controlled to stop, as in the main embodiment.

  Next, Modification 2 will be described with reference to FIG. In the second modification, a torque limiter 48 is provided on the rotating shaft of the motor 1, and a drive pulley 46 is attached to the output shaft of the torque limiter 48, and between the drive pulley 46 and the driven pulley 47. An endless belt 45 is stretched over. A slider 8 is attached to the endless belt 45. When the motor 1 rotates in the forward direction, the drive pulley 46 rotates in the forward direction and the slider 8 and the rack 6 rise. When the motor 1 rotates in the reverse direction, the drive pulley 46 rotates in the reverse direction and the slider 8 and the rack 6 move down. When the slider 8 and the rack 6 reach the upper limit position, the upper limit switch 12 comes into contact with the slider 8 and becomes ON, and the motor 1 is controlled to stop. When the slider 8 and the rack 6 reach the lower limit position, the lower limit switch 13 Is in contact with the slider 8 and is turned on, and the motor 1 is controlled to stop, as in the main embodiment.
