DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker crane-type automatic warehouse for tires for storing, storing and unloading finished and semi-finished tire products.

[0002]

2. Description of the Related Art A pallet system and a pallet-less system are known as stacker crane-type automatic warehouses for tires that store, enter and exit tires and semi-finished tires such as green tires. .

For example, FIG. 1 shows a conventional pallet system.
As shown in FIG. 1, racks 3 provided with a plurality of multi-stage shelves 2 for storing tires 9 are arranged on both sides, and a crane guide 4 travels along a central traveling path 8 while being supported by rails 5 along the rack 3. There is a pallet-type automatic warehouse for tires 1 constituted by a slide fork 6 which moves up and down while being supported by a crane guide 4.

[0004] Each shelf has a tire 9 mounted on a pallet 7.
Is stored, and after the crane guide 4 moves along the traveling path and stops in front of a predetermined shelf position in accordance with a leaving instruction,
The slide fork 6 moves to a predetermined shelf 2 and stops. Thereafter, the slide fork 6 extends horizontally from the traveling road side to the rack side, and is inserted into the insertion hole of the pallet 7 to lift the pallet 7 by the ascending operation. Then, the slide fork 6 contracts again to the traveling road side to hold the tire 9. The pallet 7 is conveyed to the unloading position by the raising and lowering operation of the slide fork 6 and the traveling operation of the crane guide 4, and the unloading of the tire 9 is completed. The empty pallet 7 after the tire 9 is removed from the pallet 7 by unloading is returned by the slide fork 6 holding the pallet 7 and moving from the unloading position to the original shelf position by the operation reverse to the above operation. You.

[0005] In the loading operation, the slide fork 6 pulls out the empty pallet 7 at a predetermined position to be stored, and the lifting and lowering operation of the slide fork 6 and the crane guide 4 are performed.
, The tires 9 to be stored are placed on the pallet 7 and conveyed to a predetermined shelf position by the reverse operation to complete the storage. or,
As a conventional palletless type automatic warehouse, for example, there is an automatic warehouse 100 for tires shown in FIGS.

[0006] Compared to the pallet method described above, the pallet 7
And the tire 109 is placed directly on the shelf 102 and stored. A circular notch 110 is provided on the shelf 102 so as to engage a part of the side surface of the tire 109, and the tire is stored. The slide fork 106 directly mounts the tire 109 on the notch, places it on the shelf 102, and lifts the tire 109 out of this engagement.
For this reason, the slide fork 10
6 needs to be moved up and down along the crane guide.

Except that the tires 109 are directly held and conveyed in place of the pallets, and that there is no operation to pick up or return an empty pallet, the operations of loading and unloading are almost the same as those of the pallet method. .

[0008]

In the case of the pallet system shown in FIG. 1, the use of the pallet requires the purchase cost of the pallet itself. In addition, at the time of unloading, return empty pallets to the original shelf position, or at the time of entry, first go to the shelf position where empty pallets are stored, move from that position and prepare, etc. Operation is required, and it takes time to enter and exit the warehouse, and the control of the entrance / exit operation becomes complicated, which further increases the cost.

As a means for solving these problems, there is a palletless system shown in FIGS. 2 and 3. The problem of the pallet system has been solved by eliminating pallets as much as possible, but a new problem has arisen.

A height required for lifting the tire from the notch of the shelf with the slide fork is required, so that the height H between the shelves becomes long. If the whole rack has the same size, a palletless system is adopted. Then, the number of shelves decreases, and the space efficiency of storing tires deteriorates. The tire may be placed directly on the flat plate of the shelf 102 without providing the notch 110 to increase the storage efficiency, but at this time, the slide fork 106 removes the tire from the upper side instead of the lower part of the tire. It becomes necessary to provide a gripper to be gripped at the tip of the slide fork, and the device is inevitably complicated.

In a conventional automatic warehouse, one stacker crane is located on the front side of both racks from the transport path side.
Only rows of shelves can be accessed. For example, if two rows were to be provided, the same automatic warehouse having a stacker crane as shown in FIG.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and has as its object to provide an automatic warehouse for tires which is simple and excellent in storage efficiency, can reduce the time required for entry and exit at low cost. I have.

[0013]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems and to achieve the object, the invention described in claim 1 of the present application provides a rack comprising a number of shelves for storing tires on both sides. In a stacker crane type automatic warehouse for tires in which a crane runs along the rack along the center traveling path along the rack to load and unload tires, each is engaged with a shelf in the rack to hold the tire. A slide plate that slides in a horizontal direction at right angles to the travel path between the shelf and the travel path, and pulls out the slide plate from the travel path side,
A push-pull device that pushes back and slides and moves up and down along a crane guide of a crane running on a traveling path, and a handling device that clamps a tire held on the slide plate from inside the inner diameter and moves up and down along the crane guide An automatic warehouse for tires, characterized in that:

In the above invention, first, the slide plate on the shelf is pulled out onto the traveling path by the push-pull device, the tire on the slide plate is directly clamped by the handling device, and is conveyed to the outlet by the traveling of the crane guide. It lowers to the height of the exit position by moving and exits.

The handling device clamps the tire at the entrance and transports the tire to a predetermined shelf by traveling a crane guide. The push-pull device and the handling device are moved to the height of the target shelf. The slide plate is pulled out and the conveyed tire is placed thereon, and the slide plate is pushed back to the rack side again to store the tire in the rack to complete the storage.

[0016] Because of the above-described operation, there is no need to use a pallet as compared with the conventional pallet system, and an operation for returning an empty pallet after unloading to the original shelf position;
It is possible to shorten the time required for loading and unloading, and to increase the speed of loading and unloading, by omitting the operation of picking up an empty pallet at the shelf position before storing and transporting the empty pallet from that position to the storing position. In addition, compared to the conventional palletless system, the space in the height direction of the shelf is reduced, and more tires can be stored than in the case of a rack having the same height, so that the storage efficiency is improved.

According to the second aspect of the present invention, in the rack, a slide plate for storing in at least two rows of shelves in a tire sliding direction is adjacent to the rack. And a connecting member capable of connecting and detaching the slide plates from each other at an end of the slide plate.

With the above construction, when the slide plate on the side of the traveling road is pulled out by the push-pull device, the slide plate on the side opposite to the traveling path is also connected to the slide plate on the front side and pulled out at the same time. There is no need to pull out each board.

The stroke of the push / pull device is the length of the slide plate in the sliding direction, and is shorter than the stroke when a conventional fork device is used. Well, access time can be shortened.

Further, even if a plurality of rows of racks are provided, it is not necessary to provide a traveling path facing each rack, and the storage capacity can be increased at a low cost with good space efficiency, and further expansion can be performed on a shelf opposite to the traveling path. Can be easily added.

According to the third aspect of the present invention, the push-pull device stops at the front of the slide plate at a specific shelf position while moving up and down along the crane guide. By pulling one slide plate on the traveling road side out of the rack with a push-pull device, the other adjacent slide plate is connected and pulled out at the same time, and the one slide plate pulled out on the traveling road side is pushed and pulled by the push-pull device. By pushing back into the rack, the connection with the other adjacent slide plate is released, and the slide plate is superimposed under the other slide plate in the rack, and the superimposed other slide plate is pulled out of the rack by a push-pull device, Also, by pushing back, the one slide plate superimposed in the rack is pulled out of the rack by a push-pull device, so that the superposition is released and the other slide plate is released. The slide plate is connected with the slide plate, the one slide plate on the traveling road side is pushed into the rack by a push-pull device, and the other adjacent slide plate is simultaneously pushed back. The tires can be transferred between the slide plate and the handling device, and the tires housed in the rack can be carried in and out.

With the above configuration, the slide plate on which the tires are mounted is pulled out onto the traveling path at the time of unloading, and the empty slide plate after the tires are removed by the handling device is removed from the adjacent shelf. , And is put on standby only with the other slide plate on the shelf on the traveling road side. For this reason, the empty slide plate can be pulled out with a short stroke in a short time to pull out at the time of entry to the warehouse, and the throughput is improved.

The tire is mounted on the uppermost one of the plurality of slide plates stacked on the shelf on the traveling road side, and the shelf side adjacent to the uppermost slide plate in order by a single stroke for one slide plate in order. The tires can be easily stored on all the adjacent shelves in the horizontal direction in the horizontal plane, and a single-stroke push-pull device can easily perform a high-throughput warehousing operation. I can do it.

If the number of shelves in the sliding direction increases, the slide plates on the respective shelves are connected to each other, and the slide plates are sequentially pulled out from the slide plate on the side of the traveling road by a single stroke of one slide plate and connected together. Since the slide plates can be sequentially stacked below the pulled-out adjacent slide plates, the slide plates can be added for each single-stroke row, thereby increasing expandability.

Further, according to the present invention, the push-pull device and the handling device are installed on a common gantry, and the gantry is provided with a crane guide. And the handling device can move up and down with respect to the gantry.

With the above structure, the lifting / lowering operation of the push-pull device and the lifting / lowering operation of the handling device can be performed by a common drive mechanism, and the operation of clamping the tire and moving up / down along the crane guide to the entrance or exit. Need not be operated by the lifting and lowering drive mechanisms of the handling device and the push-pull device, thereby saving labor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention as an automatic warehouse for tires for finished tires and raw tires as semi-finished products will be described below with reference to the accompanying drawings. First, a first embodiment of the present invention will be described. FIG. 5 is an overall side view of the tire automatic warehouse 200 showing the first embodiment of the present invention, and FIG. 6 is an overall plan view. The present invention is based on a stacker crane type automatic warehouse as shown in the figure, and its structure is a crane guide 204 that moves on rails 205 laid on the floor on a central traveling path 208 and can be moved up and down by the crane guide 204. And a rack 203 in which a plurality of rows of shelves, which are accessed by the crane on both sides along the traveling path 208, are arranged in a plurality of rows in the traveling direction.

The rack portion is provided with a slide plate 206 on which tires can be placed and slid along shelf beams 211 provided for each of the above-mentioned shelves. A stopper 221 shown in FIG. 7 is provided so as to be slidable on the outer traveling path 208 and stop at a position protruding on the traveling path 208. As shown in FIG. 7, a roller 222 is provided on the bottom surface of the slide plate 206 opposite to the traveling path 208, so that the roller 222 can smoothly slide on the upper surface of the shelf beam 211 while rotating. There is no particular limitation as long as the mechanism slides. Since the concave portion 223 is formed at the end of the shelf 211 opposite to the traveling path 208, the slide plate 206 can be stably stopped at the storage position by keeping the roller 222 at that position.

The crane portion is provided with a separate push / pull device 210 which is guided independently of the handling device 212 by a traveling crane guide 204, and the push / pull device 210 is stopped at a predetermined shelf position by the lifting / lowering operation. Then, a hand (not shown) of the push / pull device 210 is hooked on a handle 220 provided at an end of the slide plate at the shelf position on the traveling path side, and the slide plate is pulled out or pushed back.

The push-pull device may be of a self-propelled type incorporating a lifting drive mechanism for raising and lowering with a rack pinion using a crane guide as a guide. The push-pull device is suspended from above with a wire or the like. May be pulled up or down to raise and lower, but is not particularly limited. The push / pull device 210 is provided with a hand (not shown) that extends from the main body of the push / pull device 210 so as to be slidable, and is slid on the handle 220 of the slide plate 206.
It can be expanded and contracted by the length of the single unit in the sliding direction. In order to clamp the tire 209 on the slide plate 206 pulled out on the traveling path, the handling device 212 has L-shaped claws 213 facing outward at both lower ends.
Are provided so as to be freely opened and closed in the horizontal direction.
The handling device 212 descends from just above the tire 2
When the inner diameter reaches the inner diameter of the tire 09, the claw 213 spreads outward, so that the tire 209 can be clamped.

Next, the operation of entering the automatic warehouse will be described. FIG. 6 shows a tire automatic warehouse 200 according to the present invention.
In the overall plan view of FIG.
The tire 209 (not shown) is conveyed to the entrance 215 by another conveyance device such as a conveyor. Tire 2 at entrance 215
09 arrives, the crane guide 204 moves the rail 20
5 to the entrance 215 and stop. The handling device 212 and the push / pull device 210 both descend along the crane guide 204 to the position of the tire 209 that has been conveyed at the entrance 215 and stop, and the tire 209 is placed on the push / pull device 210 by a device (not shown). Put on. Next, while the push / pull device 210 is stopped, the handling device 212 descends from directly above the mounted tire 209 along the crane guide 204 with the claws 213 closed, and inserts the claws 213 into the inner diameter portion of the tire 209. Claws 2
13 is opened and the tire 209 is clamped. The crane guide 204 starts moving again, moves horizontally on the rail to the position of the shelf where the tire 209 is to be stored, and stops. After that, the handling device 212 and the push-pull device 210 are moved along the crane guide 204 to the same vertical position as the target shelf. Move to the position in the direction and stop.

Here, the push-pull device 210 is pushed onto the main body of the push-pull device 210 so that the hand of the push-pull device 210 can be hooked on the handle 220 of the slide plate 206 and pulled out. The position of the pulling device 210 is stopped in accordance with the position of the shelf. In order to store the tire 209 clamped by the handling device 212 in the rack 203, first, the push / pull device 210 pulls out the slide plate 206 onto the push / pull device 210. The handling device 212 that has clamped the tire 209 descends along the crane guide above the slide plate 206 on the push-pull device 210 and stops. The claws 213 that clamped the tire 209 are closed, and the tire 209 is released from the clamped state.
08 on the slide plate 206. at the same time,
The handling device 212 rises. After that, the push / pull device 210 moves the slide plate 20 on which the tire 209 is placed.
6 is pushed back to the rack 203 side, the tires 209 are stored in the rack 203, and the warehousing is completed. Push-pull device 21
0 and the handling device 212 return to the standby position and wait.

Next, the unloading operation will be described. When an instruction to take out the tire 209 at the target shelf position is issued, the handling device 212 and the push-pull device 210 at the standby position both move up and down along the crane guide 204 and travel along the traveling path of the crane guide 204. Move to the target shelf position. At this time, the position of the push / pull device 210 is at the position where the hand of the push / pull device 210 hangs on the handle 220 of the slide plate 206 in the same manner as at the time of loading, so that the slide plate 206 is pushed and pulled by the hand similarly to the loading operation. When pulled out onto the device 210, the handling device 2
12 is lowered, and the claw 2 is closed on the inner diameter portion of the tire 209.
13 is inserted and opened, and the tire 209 is clamped. The clamped tire 209 is mounted on the handling device 212.
Is lifted from above the slide plate 206 by the lifting operation. Thereafter, the slide plate 206 is pushed back into the rack 203. The tire 209 is transported to the exit by the traveling operation of the crane guide 204 along the traveling path and the moving operation of the push / pull device 210 and the handling device 212 along the crane guide 204 to the exit position in the same manner as when entering the warehouse. At the exit, the handling device 212
9 and release the tire 2 on the push-pull device 210.
09 is placed and transported out of the rack by another transport device outside the automatic warehouse (not shown).

In the above, the case where the handling device 212 and the push / pull device 210 move in pairs between the shelf position and the entrance or exit port is described. However, the handling device 212 clamps the tire 209 to the entrance position or exit position. When transferring, the push-pull device 210 can stop the elevating operation and stay still. For example, the handling device 212 and the pushing / pulling device 210 are arranged at positions opposing the traveling direction of the traveling path with respect to the axis of the crane guide 204, and are moved up and down while passing each other with respect to the crane guide 204 so as not to hinder the progress of each other. The push / pull device 210 can freely move up and down, and does not need to particularly relate to the operation of transporting the tire 209 other than pushing / pulling the slide plate 206.

However, when the push-pull device is moved from the shelf to the slide plate 2
06 to pull the handling device 212
When clamping 09, the main body of the crane guide 204 of the push-pull device and the handling device 212 needs to be located on the same side with respect to the axis of the crane guide 204, and the push-pull when the handling device 212 is stopped is required. In order to move up and down without interfering with the device, it is necessary that the main part of the handling device 212 be pivoted around the crane guide 204 and positioned so as to face the push-pull device 210.

Next, a second embodiment of the present invention will be described. FIG. 8 shows an overall side view of a tire automatic warehouse 300 as a second embodiment of the present invention. In the first embodiment of the present invention described above, the handling device 212 can move up and down along the crane guide 204 independently of the push-pull device 210.
