The present invention relates to an elevator parking lot value and a conveying apparatus. Conventionally, a multi-storey parking room for storing pallets for automobiles, an elevator for conveying pallets in parking rooms on each floor, and an elevator equipped with a conveying device by transporting and holding pallets from the parking space on the elevator platform of the elevators. It is common to install turntable devices for turning the pallets on which cars are stacked in order to facilitate entry and exit of cars at the parking lot and floor. In general, the turntable device lifts the pallet as a lift device and lifts the pallet lifted by the rotary device by 180 °, and then lowers the lift device to return the pallet onto the platform.

In such an elevator parking lot value, an inverter control motor is used for the rotation drive device of the turntable device so as to reduce the impact during acceleration and deceleration and increase the stopping accuracy.

However, due to the difference in the weight or the center position of the car, there is a slight error in the stop position, and when the pallet is returned to the lifting platform by lowering the lift device, the pallet collides with the pallet stopper of the lifting platform and does not lower smoothly or the pallet stopper. It may damage it. An object of the present invention is to solve such a problem in an elevator parking lot, and to provide an elevator parking lot and a transfer device which can smoothly return to a lifting platform after the turntable device turns the pallet.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, the multi-storey parking room which stores the pallet which carried the automobile, the elevator which conveys a pallet to the parking room of each floor, and the maintenance which conveys a pallet from a parking room on the elevator stand of this elevator is provided. In a parking lot having a conveying device and a turntable device for turning pallets at the floor of the storage and exit, a platform conveyance apparatus is installed at the storage floor to move the pallet of the transportation device in parallel with the conveying direction.

In addition, a feed frame in which two dogs, which face each other, which sandwiches and supports the pallet's dog receiving body, is mounted on the elevator platform and is provided with two chains which move in parallel with the pallet's conveying direction, and the pallet is conveyed. The frame moving mechanism is installed to move in the feed direction.

When storing a car, the elevator platform moves up and down to an empty parking lot. The conveying device then engages with the pallet and transports the pallet from the parking space. When the pallet comes to a predetermined position on the platform, the pallet stopper of the pallet comes into contact with the pallet stopper of the platform and stops. Maintained in this position.

Platforms with empty pallets enter and exit the floor, and the car is loaded onto the pallet. The pallet loaded with the automobile rotates in a direction of 180 ° from the turntable device in advance in order to facilitate shipping.

At the time of the change of direction, first, the conveying device reverses slightly to release engagement with the pallet, and the turntable device is raised to pick up the pallet from the platform.

Then, the platform moving device moves the platform slightly in parallel with the pallet conveyance direction, and then the turntable device rotates the pallet at 180 ° and descends to load the pallet on the platform.

Therefore, at the same time the platform feeder returns the platform to its original position, the feeder also returns to its original position and holds the pallet.

The platform then returns in front of the vacant parking space and stores the pallet with the car loaded in the parking space. When storing a pallet in a parking space, the platform conveyance apparatus transfers a pallet from a platform to a parking space and completes storage.

When leaving the car stored in the parking space, the elevator platform moves up and down to the front of the car parking space of the car to be released, and then removes the pallet stopper on which the car is loaded, in the same manner as when storing the car thereafter. The platform enters and exits to the floor, pulls the car off the pallet and returns it to the front of an empty parking garage, storing the empty pallet in the parking garage.

In addition, as shown in Fig. 7, the lifting platform moving device 6 is provided on the entry and exit floor 4 in units of two left and right. The lifting platform moving device 6 is provided with a hydraulic cylinder in parallel with the pallet conveyance direction of the feeder 23, and has a roller 62 at the front end of the piston rod 61. The platform 12 can be moved left and right by pressing.

63 is a platform positioning device for aligning the center of the platform 12 with the center of the turntable device 5 when the elevator 3 descends.

When storing the automobile 2, the platform 12 of the elevator 3 moves up and down in front of the empty parking space 13, and the empty pallet 11 is moved from the parking space 13 to the platform 12. Take it out.

When taking out the pallet 11 from the upper-right parking compartment 13 of FIG. 1, the drive sprocket 28 is first driven by the chain drive hair 27, and the two chains 26a of the feed frame 24 are carried out. (26b) rotates clockwise and at the same time, the upper side is advanced in the parking chamber 13 direction (right direction). The stopper link 35 abuts on the chain stopper 38 when the dog 34a comes to the front of the driven sprocket 32 at the right end.

The second chain 26b is a state in which the dog 34b reaches the driven sprocket 32 at the right end and rotates about 60 degrees without passing through the receiving body 36 of the pallet 11. The striker 39 stops by operating the limit switch LS at the time point at which.

In this embodiment, the chain drive motor 27 operates the two chains 26a and 26b at the same time. However, even if the first chain 26a is stopped by the chain stopper 38, the first chain 26a is stopped. Since the tension spring 29 holding the shock absorbing sprocket 30 is stretched and contracted, the second chain 26b is movable up to the position.

Subsequently, the frame moving mechanism 25 advances the feed frame 24, and the dog 34b of the second chain 26b passes under the dog receiving body 36 of the pallet 11 so as to pass the first chain 26a. Stops when the dog 34a of () contacts the dog receiving body 36 of the pallet 11.

Subsequently, the chain 26 reversely rotates to support or retract the dog receiving body 36 of the pallet 11 by two dogs 26a and 26b of the dogs 34a and 34b. When the conveyance frame 24 also retreats and the pallet 11 comes to a predetermined position on the platform 12, the stopper receiving body 46 of the pallet stopper 11 of the platform 12 abuts and stops, thereby stopping the pallet ( 11) is held in this position.

The platform 12 carrying the empty pallet 11 moves in and out to the floor 4, and loads the vehicle 2 onto the pallet 11. The pallet 11 which mounted the automobile 2 rotates 180 degrees with the turntable apparatus 5 previously so that shipment may be easy.

When changing the direction, first, the dock 34a of the first chain 26a is operated to the left to release the dog receiving body 36 of the pallet 11, and the feed frame 24 is slightly to the right. By moving, the dog 34b of the second chain 26b is separated from the dog receiving body 36, and the turntable 51 and the rotary drive device 52 are raised to lift the pallet 11 from the platform 12. Pick it up.

Subsequently, after the mobile device 6 moves the platform 12 to the left by moving the platform slightly to the left, the rotary drive device 52 drives the turntable 51 to rotate the pallet 11 by 180 °. The cylinder 56 of the lift device 53 is contracted to lower the turntable 51 and the rotary drive device 52, and the pallet 11 is mounted on the platform 12. As shown in FIG.

Thereafter, the piston rod 61 of the platform moving apparatus 6 is retracted and the platform 12 is returned to its original position.

The feed frame 24 is operated to the left side so that the dog 34b of the second chain 26b is brought into contact with the dog receiving body 36, and the pallet stopper 45 is brought into contact with the stopper receiving part 46 again. The pallet 11 is held, and the dog receiving body 36 of the pallet 11 is fitted by operating the dog 34a of the first chain 26q to the right.

The platform 12 then returns to the front of the empty parking space and stores the pallet in the parking space.

When storing the pallet 11 in the parking space 13, the transfer frame 24 advances toward the parking compartment 13 and the two chains 26a and 26b of the transfer frame 2 advance simultaneously. When the pallet 11 comes to a predetermined storage position, the first chain 26a stops.

The second chain 26b is a state in which the dog 34b reaches the driven sprocket 32 on the right side, rotates about 60 degrees, and does not collide with the dog receiving body 36 of the pallet 11, and can pass therethrough. The striker 39 stops by operating the limit switch LS.

When the feed frame 24 is retracted so that the dog 34b of the second chain 26b passes under the dog receiving body 36 of the pallet 11, the chains 26a and 26b are reversed and retracted. When it reaches to the predetermined position on the platform 12, it stops and the storing of the pallet 11 stops.

When the automobile 2 is stored in the parking lot 13 on the left side, it operates in the reverse direction to the above.

When leaving the car 2 stored in the parking space 13, the elevator 12 moves up and down to the parking space 13 where the car 2 is stored, which the platform 12 of the elevator 3 leaves. As in the case of storing, the pallet 11 which has loaded the car 2 is taken out, the platform 12 enters and exits and moves to the floor 4, and the car 2 is moved from the pallet 11 to the empty parking space. (13) Returning to the front, the empty pallet 11 is stored in the parking space 13.

The elevator parking lot of the present invention may be damaged when the turntable device turns the pallet 11 and then returns to the platform, when the pallet stopper or dog receiving body collides with the pallet stopper or dog of the platform. It is possible to smoothly move in and out without interruption of descent.
