The car is accommodated in each parking room by horizontally moving the pallet between the lifter and each parking room (7) (8) (11) (12).
JP-A-1-219261

  In the above-described three-dimensional parking apparatus, when the pallet is moved horizontally, if the positions of the pallet and the moving device are shifted, there is a possibility that the movement of the pallet may be hindered. However, since one of the pallet and the moving device is provided on the lifter side (moving side) and the other is provided on the structure (fixed side), it is not easy to align both positions with high accuracy.

  An object of the present invention is to provide a three-dimensional parking apparatus that can smoothly move a pallet horizontally between a parking room and a lifter.

In order to solve the above-mentioned problems, the present invention provides a structure having a multi-stage parking room, a pallet accommodated in each parking room, a lifter that can be raised and lowered along the structure, and a lifter. And a pallet transfer device for transferring the pallet between the lifter and the parking room, wherein the pallet transfer device includes a pair of support arms swingably provided on the lifter, and And a pair of support arms arranged symmetrically with respect to the pallet transfer direction and with the free end toward the parking chamber, and each free end The pallet is moved between the lifter and the parking room by rotating the friction wheel in a state where the pallet guide plate is sandwiched between the pair of friction wheels . Water behind the entrance / exit A movable pallet stopper is provided, and this pallet stopper is brought into contact with the pallet arranged at the loading / unloading port from the back side or stopped immediately before coming into contact with the pallet from the back side. The pallet stopper is provided with a detection device, and when the detection device detects that the distance between the pallet disposed at the loading / unloading port and the pallet stopper has reached a predetermined value, the pallet stopper A multi-story parking device is provided that stops the vehicle.

  In this way, by providing a pair of support arms that can swing the pallet guide plate so as to be swingable, even if the position of the pallet is slightly shifted, the shift can be absorbed by the swing of the support arm. The guide plate of the pallet can be securely held.

  By the way, a large load may be applied to the pallet when the car is moved into or out of the multi-story parking device. That is, when an automobile that has entered from the loading / unloading port is suddenly stopped on the pallet, a large load is applied to the pallet toward the back side (that is, the side opposite to the loading / unloading port) due to the inertial force of the vehicle. Further, when the automobile is started suddenly at the time of delivery, a large load toward the back side is applied to the pallet due to the reaction of the force that starts the automobile. When a large load is applied to the pallet in this way, the pallet collides violently with other members, which may cause noise and damage other members.

  Therefore, by restricting the movement of the pallet arranged at the entrance / exit to the back side by the pallet stopper, the pallet can be fixed at a predetermined position even when a large load toward the back side is applied to the pallet. , It is possible to avoid a severe collision between the pallet and other members. Further, if the pallet stopper and the pallet are separated from each other, there is a possibility that noise is generated or the pallet stopper is damaged due to the collision between the pallet and the pallet stopper. Therefore, when the size and position of the pallet placed at the loading / unloading port is slightly different by bringing the pallet stopper into contact with the pallet placed at the loading / unloading port from the back side or stopping just before contacting the pallet Even so, since the distance between the pallet stopper and the pallet can be substantially zero, the above-described problem can be avoided. Further, when the pallet is moved up and down, the pallet stopper is retracted to a position away from the pallet, thereby preventing interference between the pallet and the pallet stopper.

  Further, in the above-described three-dimensional parking apparatus, the lifter is provided with a locking lever pivotally supported so as to protrude and rotate outward from the lifter, a stopper is provided in the structure constituting the parking chamber, and the locking lever is attached to the lifter. The lifter can be supported by a simple mechanism by lowering the lifter in a state of protruding and rotating outward and engaging the locking lever from above the stopper.

  Further, when the lifter is provided with a cart that can move in the horizontal direction together with the pallet transfer device, the cart needs to be fixed at a predetermined position on the lifter. The carriage fixing device includes a pair of turning frames provided on the carriage so as to be capable of turning, a pair of dog clamp members provided on each turning frame and configured to clamp dogs protruding from the lifter from both sides in the moving direction of the carriage, If the biasing means for turning the pair of turning frames in the direction for releasing the clamp by the dog clamp member and the solenoid for turning the pair of turning frames in the direction for clamping the dog by the dog clamp member are used, the solenoid The cart can be easily fixed or released.

  In addition, a vacant space may be provided in front of the entrance / exit (external side), and a turntable for changing the direction of an automobile, for example, is provided in the front vacant space. If the parking room is formed in multiple stages above the front open space, the space above the front open space can be effectively used as a parking space.

  As described above, according to the three-dimensional parking apparatus of the present invention, the pallet can be smoothly moved horizontally to the parking room.

Due to the elastic force of the compression springs 35 and 35 ', the support arms 29 and 29' are constantly urged in the direction in which the tip ends are closed, thereby forming a parallel link mechanism.

  The friction wheels 30 and 30 ′ are rotationally driven by the first drive mechanism 36. The first drive mechanism 36 includes a drive motor 37 provided at one end of the movable table 26, a drive shaft 38 protruding upward from the drive motor 37, and a drive gear 39 fixed to the drive shaft 38.

  Transmission gears 40 and 40 'are rotatably provided on the first pivots 28 and 28' provided on the support arms 29 and 29 'via bearings. The transmission gears 40 and 40 'are fixed to the inner surfaces of the support arms 29 and 29'.

The tension wheels 44 and 44 'are engaged with the endless chains 43 and 43', respectively, and the tension of the endless chains 43 and 43 'can be adjusted by adjusting the position in the width direction as appropriate.

  The moving table 26 is translated in the width direction by the second drive mechanism 45. The second drive mechanism 45 meshes with a drive motor 46 provided at a predetermined portion of the mounting plate 24 of the carriage 12, a rack jack 47 connected to the drive motor 46, and the rack jack 47, and slides in the width direction. Possible rack 48. The end portion of the rack 48 is connected to the end surface of the box 26 b of the moving base 26 via the pressing member 49 and the joint 50. When the drive motor 46 is rotationally driven, the rotational motion is converted into a linear motion via the rack jack 47 and the rack 48, whereby the movable table 26 can be translated in the width direction along the guide rails 25 and 25 '. . The other end of the rack 48 of the rack jack 47 is connected to the moving base of the other pallet transfer device 23b. By rotating the drive motor 46, the pallet transfer devices 23a and 23b can be moved simultaneously. Translate.

  The pallet transfer device 23 a is provided with a first position detection mechanism 51 for detecting the position of the moving base 26 that is translated by the second drive mechanism 45. In addition, here, the movement to the side where the movable stand 26 protrudes outward in the width direction is called forward, and the movement to the opposite side is called backward. The first position detection mechanism 51 includes a mounting bracket 52 disposed in parallel to the side of the guide rail 25, and first to fourth proximity switches 53a to 53a provided at predetermined intervals on the mounting bracket 52. 53d and an operating rod 54 fixed to the movable table 26 and extending in the width direction. When the movable table 26 moves in parallel and approaches the first to fourth proximity switches 53a to 53d, the switches 25a to 25d are operated, and the position of the movable table 26 (friction wheel 30) is detected. In this case, when the first proximity switch 53a and the second proximity switch 53b are operated, the moving base 26 of one pallet transfer device 23a is at the forward end position (indicated by a virtual line at the left end in FIG. 8), The friction wheel of the other pallet transfer device 23b is in the retracted end position (not shown). When the second proximity switch 53b and the third proximity switch 53c are activated, the friction wheels of the pallet transfer devices 23a and 23b are both in an intermediate position (shown by a solid line in FIG. 8). When the third proximity switch 53c and the fourth proximity switch 53d are operated, the friction wheel 30 of the pallet transfer device 23a is in the retracted end position (not shown), and the friction wheel of the pallet transfer device 23b is in the forward end position. (Indicated by an imaginary line at the right end of FIG. 8).

  Next, accommodation and removal of the automobile A in the multi-story parking apparatus having the above configuration will be described. In the initial state, it is assumed that the car A is not accommodated in the parking chambers 2 of the main garage rows 3a and 3a and the sub garage rows 3b and 3b of the structure 1, and the lifter 10 is at the lowest end position, that is, entry / exit It is assumed that the pallet 8 is not placed on the lifter 10 at the mouth.

  When the automobile A is accommodated in the parking room 2 of the main garage line 3a, first, the lifter 10 is raised to the desired height of the parking room 2 by an appropriate drive mechanism. In this state, the fixed rail 4 of the parking chamber 2 of the main garage row 3a and the second guide rails 19 and 19 of the carriage 12 are positioned on the same straight line in the width direction, and the support rail 22 between the sub garage row 3b. -22 and the 1st guide rails 14 and 14 of the raising / lowering body 11 are located on the same front-back direction straight line. When the automobile A is accommodated in the parking chamber 2 of the auxiliary garage row 3b, the carriage moving drive motor 21 is further operated from the above state, and the carriage 12 is moved to the first guide rails 14 of the elevating body 11. 14, the carriage 12 is horizontally moved along the support rails 22 and 22 between the auxiliary garage trains 3b and 3b. At this time, the fixed rails 4 and 4 of the parking chamber 2 of the auxiliary garage trains 3b and 3b and the second guide rails 19 and 19 of the carriage 12 are positioned on the same straight line in the width direction.

  Then, the drive motor of the 2nd drive mechanism 45 provided in the pallet transfer apparatus 23a is operated, and the rack 48 is protruded in the width direction. As a result, the moving base 26 moves forward (moves outward in the width direction) along the guide rails 25 and 25 '. When the operating rod 54 comes close to the first proximity switch 53a and the second proximity switch 53b, the forward end position of the moving base 26 is detected. As a result, the second drive mechanism 45 of the pallet transfer device 23a is stopped, and the pair of friction wheels 30 and 30 'are held in a state of protruding from the carriage 12 outward in the width direction. Then, the guide plate 8a on the lower surface of the pallet 8 accommodated in the parking chamber 2 is sandwiched between the friction wheels 30 and 30 'that are always urged in the direction in which they are pressed against each other by the elastic force of the compression springs 35 and 35'. At this time, since the support arms 29 and 29 'swing around the first pivots 28 and 28' by the action of the parallel link mechanism, even if there is an error in the mounting position of the guide plate 8a on the lower surface of the pallet 8, When the guide plate 8a hits one of the friction wheels 30 and 30 ′ and the support arms 29 and 29 ′ swing, the guide plate 8a can be securely held by the friction wheels 30 and 30 ′.

  When the guide plate 8a is sandwiched between the friction wheels 30 and 30 'in this manner, the drive motor 37 of the first drive mechanism 36 and the drive motor 46 of the second drive mechanism 45 are operated almost simultaneously with this, and the drive gear 39 is rotationally driven. At the same time, the rack 48 is retracted. The rotational driving force of the drive gear 39 is transmitted to the friction wheels 30 and 30 'via the transmission gears 40 and 40', the endless chains 43 and 43 ', and the chain wheels 41, 41', 42 and 42 '. On the other hand, the movable table 26 moves backward (accommodates inward in the width direction) as the rack 48 moves back. That is, since the friction wheel 30.30 ′ moves backward while rotating, the guide plate 8a of the pallet 8 sandwiched between the friction wheels 30 and 30 ′ thereby causes the carriage 12 to move by the friction force with the friction wheels 30 and 30 ′. Sent to the side. As a result, the leg 9 of the pallet 8 is transferred from the fixed rails 4 and 4 of the parking chamber 2 to the second guide rails 19 and 19 of the carriage 12, and the pallet 8 is transferred onto the lifter 10. Thereafter, the operating rod 54 moves backward as the moving table 26 moves backward, and when the second proximity switch 53b and the third proximity switch 53c operate, the first drive mechanism 36 and the second drive mechanism 45 stop. . At this time, the pallet 8 is positioned and held at a fixed position on the carriage 12 by sandwiching both ends in the width direction of the guide plate 8a of the pallet 8 with the friction wheels of the pallet transfer devices 23a and 23b.

  When the empty pallet 8 is transferred to the lifter 10 in this way, the lifter 10 is lowered and stopped at the entrance / exit 6 (in this embodiment, the lowermost position between the main garage trains 3a and 3a). In this state, the automobile A on the turntable 7 in the front open space 5 of the structure 1 enters the structure 1 through the loading / unloading port 6 and stops on the pallet 8. At this time, if the vehicle A is stored without being sufficiently decelerated and is suddenly stopped on the pallet, a large load is applied to the pallet 8 toward the back side (the traveling direction of the vehicle A). In order to restrict the movement of the pallet 8 due to this load, the three-dimensional parking apparatus according to the present embodiment is provided with a pallet stopper 200 having the following configuration. In the description of the pallet stopper 200, the front end (roller 201) of the pallet stopper 200 protrudes forward (right side in FIGS. 9 to 11), and the front end of the pallet stopper 200 is separated from the pallet 8. Then, the backward direction is referred to as the rear (left side in FIGS. 9 to 11).

  The pallet stopper 200 is provided on the back side of the pallet 8 disposed on the loading / unloading port 6 (the side opposite to the side where the automobile A enters and exits). As shown in FIGS. 9 and 10, the pallet stopper 200 includes a roller 201 having a rotation axis in the width direction, a support tool 202 that supports the roller 201, a rack arm 203 that extends rearward from the support tool 202, and a rack A pinion 204 that meshes with the arm 203 and a motor 205 that rotationally drives the pinion 204 are provided. By rotating the motor 205, the roller 201 can be moved in the front-rear direction. The pallet stopper 200 is provided with a first sensor 220 for detecting the reverse stop position of the roller 201 and a second sensor 230 for detecting the advance limit position of the roller 201. An operating rod 206 bent in a bowl shape is fixed to the support 202 of the roller 201.

  The pallet stopper 200 is provided with a detection device 210 for determining the stop position of the roller 201. The detection device 210 moves forward and backward with the roller 201. As shown in FIG. 11, the detection device 210 is fixed to the support 202 and has a substantially C-shaped attachment 211 in a top view, a support bar 212 penetrating the attachment 211 in the front-rear direction, and the rear of the support bar And a third sensor 213 that detects the position of the end 212a (the left end in FIG. 11). A spring 214 is attached to the outer periphery of the support bar 212. The spring 214 is sandwiched between the fixture 211 and the locking portion 215 provided on the support bar 212 and is held in a compressed state. Thereby, the support bar 212 is urged in a direction protruding forward. At this time, the distal end portion of the support bar 212 is disposed so as to slightly protrude from the distal end portion of the roller 201. A freely rotatable ball 216 is disposed at the tip of the support bar 212.

  Next, the operation of the pallet stopper 200 will be described. When the pallet 8 is arranged at the loading / unloading port, the motor 205 is driven to cause the roller 201 to protrude forward (pallet 8 side). Prior to the roller 201, the ball 216 provided at the tip of the support bar 212 of the detection device 210 contacts the stopper receiving plate 8 b provided at the end of the pallet 8. As a result, the support bar 212 is pushed backward relative to the fixture 211, and the rear end 212 a of the support bar 212 is detected by the third sensor 213. Simultaneously with this detection, the motor 205 is stopped and the roller 201 is stopped. At this time, the dimension and position of each member are set so that the roller 201 comes into contact with the stopper receiving plate 8b of the pallet 8 or stops immediately before the contact. At this time, if the roller 201 is strongly pressed against the stopper receiving plate 8b, a load applied to the pallet 8 is directly applied to the motor 205, and the motor 205 may be damaged. preferable. As a guideline, the roller 201 may be in a rotatable state in a contact state. Further, when the motor 205 is not stopped by the detection device 210 due to some trouble, the motor 205 is stopped by detecting the operating rod 206 fixed to the support 202 of the roller 201 by the second sensor 230 ( (See the virtual line in FIG. 10).

  In this state, the automobile A is placed on the upper surface of the pallet 8. At this time, the movement of the pallet 8 to the back side is restricted by the pallet stopper 200, so that the pallet 8 can be stopped even if the vehicle A is suddenly stopped and a load is applied to the pallet 8 toward the back side (left direction in the figure). Since it can fix to a predetermined position, the collision with a pallet and other members (for example, structure 1) can be avoided. Further, since the gap between the stopper receiver 8b of the pallet 8 and the roller 201 is substantially zero, noise and impact when the pallet 8 and the roller 201 collide can be suppressed. Further, when the pallet stopper 200 is brought into contact with the stopper receiver 8b with the roller 201 or the ball 216, even when the pallet 8 is slightly lowered when the automobile is put on the pallet 8, the roller 201 and the ball 216 are rotated. Therefore, the load is not applied to the rack arm 203 or the support bar 212.

  When the automobile A is placed on the pallet 8, the motor 205 is driven to rotate in the direction opposite to the above, and the roller 201 is moved backward. When the detection plate 206 fixed to the support 202 of the roller 201 is detected by the first sensor 220, the position of the motor 205 is stopped. Thereafter, the pallet 8 on which the automobile A is placed is raised. Thus, by retracting the roller 201, it is possible to reliably avoid a situation where the pallet 8 and the roller 201 interfere when the pallet 8 is raised (or lowered). Even when the car A placed on the pallet 8 is unloaded, even if the car A is suddenly started at the time of unloading by restricting the movement of the pallet 8 toward the back side by the pallet stopper 200 as described above. The pallet 8 can be fixed at a fixed position.

  In this way, the pallet 8 on which the automobile A is placed is raised to the height of the parking room 2 in which the pallet 8 was originally stored, and the fixed rails 4 and 4 of the parking room 2 and the second guide rail 19 of the carriage 12 are raised. 19 is arranged on the same width direction straight line.

  Thereafter, the drive motor 37 of the first drive mechanism 36 and the drive motor 46 of the second drive mechanism 45 provided in the pallet transfer device 23a are driven, the drive gear 39 is rotated, and the rack 48 is moved outward in the width direction. To protrude. Then, the friction wheels 30 and 30 ′ move forward while rotating in the direction of carrying out the pallet 8 to the parking chamber 2 side, whereby the guide plate 8a of the pallet 8 sandwiched between the friction wheels 30 and 30 ′ It is carried out to the parking room 2 side by the frictional force of the cars 30 and 30 ′. As a result, the leg 9 of the pallet 8 is transferred from the second guide rails 19 and 19 of the carriage 12 to the fixed rails 4 and 4 of the parking room 2, and the pallet 8 is transferred to the parking room 2. When the operating rod 54 approaches the first proximity switch 53a and the second proximity switch 53b as the moving table 26 moves forward, the first drive mechanism 36 and the second drive mechanism 45 of the pallet transfer device 23a. The pallet 8 is positioned and held at a fixed position in the parking chamber 2.

  When the automobile A is accommodated in the desired parking chamber 2 in this way, the drive motor 46 of the second drive mechanism 45 of the pallet transfer device 23a is operated to retract the rack 48. As a result, the pallet 8 is disengaged from the guide plate 8a and the friction wheels 30 and 30 'are retracted. When the operating rod 54 approaches the second proximity switch 53b and the third proximity switch 53c, the second drive mechanism 45 is stopped, and the friction wheels 30 and 30 'are held at the original fixed positions.

  The three-dimensional parking apparatus can be provided with a lifter support device 56 (see FIG. 12) for temporarily supporting the lifter 10 when the lifter 10 stops at the height of each parking chamber 2 of the structure 1. The lifter support device 56 is fixed to the elevating body 11 and has a rectangular parallelepiped support case 57 that forms a space inside and has an open outer surface, and a pivot 58 that spans between the side plates 57a and 57a of the support case 57. And a locking lever 59 in which a boss 59a is rotatably inserted into the pivot 58. The locking lever 59 is always urged toward the inside of the support case 57 by the return spring 60. The locking lever 59 is provided with a locking claw 59b at its tip, and a protruding piece 61 is provided on the boss 59a. A rotation restriction member 62 that restricts the rotation of the locking lever 59 by contacting the rear end surface of the locking lever 59 is provided at a predetermined position in the support case 57. A round bar-like stopper 63 is fixed to the upper surface of a fixed frame (not shown) constituting the structure 1 on the pallet entry / exit side of each garage row. The stopper 63 is disposed at a position where the locking claw 59b of the locking lever 59 can be engaged from above. When the locking lever 59 is engaged with the stopper 63, the fixed rails 4 and 4 in the width direction of the parking chamber 2 and the second guide rails 19 and 19 in the width direction of the carriage 12 are on the same plane and on the same straight line. The positions of the locking lever 59 and the stopper 63 are adjusted so as to be arranged in the above. A locking lever operating actuator is provided at a predetermined position in the support case 57. This actuator includes, for example, a solenoid 64, a plunger 64 a that protrudes and retreats by the solenoid 64, and a connecting link 65 that connects the tip of the plunger 64 a to the protruding piece 61 of the locking lever 59.

  Next, the operation of the lifter support device 56 will be described.

  First, the lifter 10 is raised and disposed at a position that is the height of the desired parking room 2. When the locking lever 59 provided on the lifter 10 passes through the stopper 63 of the parking chamber 2 and is positioned above the stopper 63 by a predetermined dimension (for example, 5 to 10 cm), the lifter 10 stops. Simultaneously with the stop of the lifter 10, the solenoid 64 is excited to retract the plunger 64 a, and the locking lever 59 is rotated about the pivot 58 against the elastic force of the return spring 60. As a result, the locking lever 59 protrudes from the support case 57, and the locking claw 59 b faces the stopper 63. By lowering the lifter 10 in this state, the locking lever 59 is engaged with the stopper 63. Accordingly, the lifter 10 is temporarily supported by the structure 1 and the fixed rails 4 and 4 of the parking chamber 2 and the second guide rails 19 and 19 of the carriage 12 are arranged on the same straight line. Even if the solenoid 64 is de-energized after the stopper 63 and the locking lever 59 are engaged, the tip of the locking lever 59 and the stopper 63 are engaged in the rotation direction of the locking lever 59. As a result, the locking lever 59 does not return to its original state, and the temporary support state is maintained.

  When the pallet 8 is transferred, the lifter 10 is slightly raised. As a result, the engagement between the locking lever 59 and the stopper 63 is released, and the locking lever 59 is rotated by the elastic force of the return spring 60 and retracts into the support case 57. Thereby, the lifter 10 can be brought into a state where it can be raised and lowered.

  The multi-story parking device can be provided with a cart fixing device 100 for stopping and fixing the cart 12 at a fixed position on the lifting body 11. The carriage fixing device 100 is attached to the carriage 12 and holds the carriage in place by clamping a dog projecting from the lifting body 11. As shown in FIGS. 13 and 14, for example, the cart fixing device 100 includes a base plate 101 fixed to the cart, fulcrum shafts 102a and 102b, and swivel frames 103a and 103b. The fulcrum shafts 102a and 102b are arranged side by side along the moving direction of the carriage (left and right in the figure) at the center of the base plate 101, and the swivel frames 103a and 103b are rotatably attached to the fulcrum shafts 102a and 102b. It is done. The fulcrum shafts 102a and 102b are arranged on the path of the dog 116 of the elevating body 11 (see FIGS. 15 to 17). The turning frames 103a and 103b are arranged symmetrically. Inclined levers 104a and 104b that are inclined by a predetermined angle from the lower part of the free end are provided at the free ends (the ends opposite to the fulcrum shafts 102a and 102b) of the swing frames 103a and 103b. Dog clamp members 105a and 105b are provided opposite to each other at the inner ends of the tilt levers 104a and 104b (ends on the fulcrum shafts 102a and 102b side).

  Solenoids 106 a and 106 b are arranged symmetrically at both ends of the base plate 101. The distal ends of the plungers 106a 'and 106b' of the solenoids 106a and 106b are pivotally attached to pivoting members 108a and 108b projecting from the base ends of the swivel frames 103a and 103b via the connecting links 107a and 107b. The When the plungers 106a ′ and 106b ′ are attracted by exciting the solenoids 106a and 106b, the swing frames 103a and 103b are supported on the fulcrum shafts 102a and 102b via the connecting links 107a and 107b and the pivoting members 108a and 108b. Turn (see arrow X in FIG. 13).

  The base plate 101 is provided with first stoppers 109a and 109b for restricting the turning in the direction in which the free ends of the turning frames 103a and 103b are raised (turning in the X direction in FIG. 13) at a predetermined position. When the stopper receiving members 110a and 110b of the swing frames 103a and 103b are in contact with the first stoppers 109a and 109b, the swing of the swing frames 103a and 103b is restricted (see the phantom line in FIG. 13).

  On the base plate 101, return springs 111a and 111b are provided at symmetrical positions. One ends of the return springs 111a and 111b are fixed to spring locking members 112a and 112b provided on the base plate 101, and the other ends of the return springs 111a and 111b are spring locking members 113a protruding from the base end portions of the swing frames 103a and 103b. -113b is fixed. Due to the pulling force of the return springs 111a and 111b, the swing frames 103a and 103b are constantly urged in the direction of lowering the free ends (see arrow Y in FIG. 13).

  The base plate 101 is provided with second stoppers 114a and 114b for restricting the turning in the direction in which the free ends of the turning frames 103a and 103b are lowered (turning in the Y direction in FIG. 13) at a predetermined position. When the stopper receiving members 115a and 115b of the swing frames 103a and 103b are in contact with the second stoppers 114a and 114b, the swing of the swing frames 103a and 103b is restricted.

  The dog 116 protrudes from the stop position of the carriage 12 and is formed to have a length clamped between the dog clamp members 105a and 105b arranged to face each other.

  The operation of the cart fixing device 110 will be described below.

  First, when the carriage 12 is driven, the solenoids 106a and 106b are excited to turn the turning frames 103a and 103b so as to contact the first stoppers 109a and 109b. By this turning, the tilt levers 104a and 104b provided on the turning frames 103a and 103b are retracted from the passing position of the dog 116 to be in the unlocked state (see FIG. 15). When the carriage 12 is run in this state, the dog provided on the carriage 12 does not come into contact with the tilt levers 104a and 104b at all, so the carriage 12 runs smoothly.

  Next, when the carriage 12 is stopped and fixed at a fixed position on the elevating body 11, the solenoids 106a and 106b are de-energized before the dog 116 reaches the fixed position, and the swing frames 103a and 103b are connected to the return springs 111a and 111b. It is swung until it comes into contact with the second stoppers 114a and 114b by the elastic force. By this turning, the tilt levers 104a and 104b are returned to the passing position of the dog 116 to be locked. When the carriage is run in this state, one tilt lever 104a comes into contact with the dog 116 provided on the carriage 12 immediately before the carriage reaches the fixed position. Thereby, one turning frame 103a to which the inclination lever 104a is attached turns against the return spring 111a, and the inclination lever 104a passes while being spread by the dog 116 (see FIG. 16).

  When the tilt lever 104a passes the dog 116, the dog clamp member 105b attached to the other tilt lever 104b comes into contact with one end surface of the dog 116, and the carriage 12 is stopped. At the same time, one of the tilt levers 104a is disengaged from the dog 116 and swivels until the swivel frame 103a comes into contact with the second stopper 114a by the return spring 111a. As a result, the tilt lever 104a returns to the locked state, the dog 116 is clamped between the dog clamp members 105a and 105b, and the carriage 12 is fixed (see FIG. 17).

  Thereafter, when traveling with the carriage 12 being released, the solenoids 106a and 106b are energized and the turning frames 103a and 103b are turned to the unlocked position, whereby the dog clamp members 105a and 105b of the tilt levers 104a and 104b are dogged. It is only necessary to retreat from the passing position of 116 and enter the unlocked state.
