CONSTITUTION:After pre-treatment, in the case where each plate work W to be carried in being held by a gripper 6 of a loader 6 is accumulated thereat, a pair of front and rear moving rollers 25 being retractable so as to open or close an upper opening of a frame 23 is made to come into a state of being closed as in illustration, and these plate works W are mounted on plural rollers 24. Next, each motor 36 is synchronously rotated whereby each of these moving rollers 25 is simultaneously opened in front and the rear, then each plate work W is bent to some extent in a state of being hung down downward from its central part, and transferred onto a pallet P as making a coherent area to the pallet P increase by degrees. After the plate work W is completely mounted on the pallet P, the motor 36 is reverse in rotation, causing the moving roller 25 to be closed, and afterward the same operation is repeated, thus the plate work W is piled up.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stocking device for plate materials that orderly deposits transferred plate materials at a fixed location, and more particularly to a stocking device for plate materials having elasticity that allows bending and deformation of sheet metal or the like.

For example, a sheet metal processing line consisting of machine tools such as a punch press machine and a shearing machine is connected to a loading/unloading station of an automated warehouse, and the sheet metal discharged from the automated warehouse with its pallets is directly supplied to the sheet metal processing line. If the sheet metal that has been processed can be stacked on a pallet and the stacked sheet metal can be returned to the automated warehouse along with the pallet,
Even when there are many types of sheet metal to be handled and the type of sheet metal supplied to the processing line is changed for each small lot, the change can be done in a short time.

It has the advantages of minimizing waiting time on the processing line, increasing production efficiency, and making it easy to adjust processing setups, but stacker cranes are used between each storage section of the automated warehouse and the loading/unloading station. Since automatic transport and automatic pick-up and delivery are performed by the system, the processed sheet metal stacked on the pallet in order to be stored in the automated warehouse again is neatly placed on the pallet with a positional accuracy within a range of at least several tens of degrees in the front, back, left and right directions. must be deposited. If the stacking condition on the pallet is poor, it may become impossible to transfer the sheet metal from the processing line to the stacker crane or from the stacker crane to the designated storage compartment on the rack, or the sheet metal may collapse during the delivery. If the above problems occur frequently, it becomes impossible to connect the sheet metal processing line and the automatic warehouse as described above.

Therefore, the present invention is capable of stacking sheet metals on pallets in an orderly manner with high positioning accuracy, and is mainly installed in sheet metal processing lines such as those described in -2 above, and at connection points with other lines such as automated warehouses. The object of the present invention is to provide a sheet material stocking device that can realize a system that connects a sheet metal processing line and an automatic warehouse as described above without causing any trouble. .

The sheet metal cut by the shearing machine (2) is discharged by a conveyor (11) at the rear, and transported to another line by a conveyor or cart (not shown) connected to the rear.

On the starting end side of the sheet metal processing line, a pallet truck (14) that moves on the L/-ru t13) is provided as a sheet metal supply station [12], and the movement end point C of the pallet truck (14) is provided. The loading/unloading station (15) is aligned with the stacking station (two-dot chain line in FIG. An automated warehouse (19) is installed parallel to the warehouse. (21) is a running rail of the stacker crane (18), and the stacker crane (18) is an automated warehouse [19].
) direction and sheet metal 3 - This type is equipped with a transfer fork (not shown) that can protrude both forward and backward in the direction of the processing line.

Next, the above-mentioned drop-in stock device (9) according to the present invention will be described.
), the stocking device (9) is a pit (22) formed in the floor, as shown in FIGS. 3 to 5.
With a frame (23) installed inside.

A movable roller device (25) consisting of a large number of movable rollers (24) that can move along the frame wall from the side to the side of the frame (23), and a sheet metal holder in the lower part of the frame [23]. The sheet metal receiver adjacent to the receiving station (16) of the automatic warehouse from the stop 1 device C (1 dot chain line in Figure 1) is a sheet metal support that can be moved between the transfer 1)' l positions (2 dot chain line in Figure 1). It consists of a trolley (26), each of which is as follows.

That is, the frame (23) has an opening (27) larger than the size of the sheet metal on its upper surface, and a large number of moving rollers (24) cover the internuclear space "1 (27)."

In this state, the sheet metal station is supported on the moving roller (24), and the moving roller C24) moves backward toward the side of the frame. , so that they are deposited on the lower plate material support cart (26).

The moving roller device (25) includes a sprocket (28) provided approximately in the center of the top surface of the frame, a sprocket (29) C31) provided at the end of the top surface of the frame, and a sprocket [32) provided at the bottom of the side surface of the frame. (
28) (29) A rotating chain (33) is attached to (31M32), and both ends of the chain are attached to the chain [33].

It consists of a large number of moving rollers (24) to which are fastened (34), and a drive motor (36) connected to a chain (35) to the sprocket (31). Drive motor (36) of the device (25)
are rotated in the appropriate directions in synchronization, the multiple moving rollers (24) in the state shown in the third figure, which cover the opening (27) on the top surface of the frame, will open and move from the center to the left and right at the same time. ing. In addition, C37 in Figure 415)
(38) is a bearing rotatably supporting the outer cylinder (24a) of the moving roller (24), and (39) is a tensioning device of i, t sprocket C32).

Similar to the pallet cart [14), the plate material support cart C26) runs on the rail (41) in the pit I-(22) from the lower position of the frame (23) adjacent to the warehousing station C16) of the automated warehouse. The pallet receiving table (42) on the top surface is moved up and down by a pantograph-shaped lifting/lowering device (43), and its two-sided height can be changed. .

Next, the processing steps in the sheet metal processing line of the above embodiment and the sheet metal stacking process using the stock device (9) will be explained.

That is, in order to start processing at the - line, first move the pallet truck (14) of the sheet metal supply station ([2) to the receiving position shown by the two-dot chain line in Figure 1, and then Operate the stacker crane (18) in the warehouse as appropriate to load the sheet metal surface of the desired size, thickness, and material onto the rack C.
17) Unload the entire pallet (G) from the specified storage section above, and move the pallet truck [14
) The pallet truck (14) on which the 7 sheet metal W to be delivered upwards was transferred along with the pallet (G) moves on the rail (13), returns to the starting position shown by the one-dot chain line in Figure 1, and stops. Ok,
A sheet metal separation device (old) using magnets installed at the starting point is activated to separate the second sheet metal.

Then, place the separated top sheet metal surface on the loader (
5), the material is suction-lifted and conveyed, and then supplied to the punch press machine (1), where it is punched or, following the punching, sheared.

That is, when performing shearing processing following punching, the punched sheet metal W gripped by the loader (force gripper (6)) is passed through the stocking device (9) and placed in the shearing machine (2). When carrying and supplying the metal to the top of the table (2a) and only performing punching, a certain amount of the sheet metal (b) held by the loader (forced) is deposited via the dropping and stocking device (9) according to the present invention, and then
Once the automatic warehouse (19)<s pallet (g) is returned,
After storing the goods in a designated storage section in the automated warehouse, they can be taken out from another unloading station as needed and then placed in other storage areas.
- Transport it to Elaine. That is, to explain in detail the operation of the stock device (9), the loader (7)
) The sheet metal W is held on the moving roller [24] by the gripper (6) of the moving roller (24).
) are opened and moved to the left and right at the same time by rotating the drive motor C36) in synchronization as described above (arrow A in Fig. 3).
By doing so, the pallet is curved while hanging downward from the central portion, gradually increasing the contact area (Wa) to the pallet (T) on the plate support cart (26).
-(1') Transferred to J: (Figure 6 (A) → (C)). At this time, the gripping of the edge of the plate by the gripper (6) is as follows:
The moving roller C24) completes its retreat, and the entire surface of the sheet metal W excluding the side edge gripped by the gripper (6) is placed on pallets 1 to CP.
), or it may be released before that point, for example, when about half of the surface of the sheet metal is in close contact with each other, as shown in FIG. 6 (cutaway illustration).

After the sheet metal (E) is completely placed on the pallet (P)-, the drive motor (36) is reversed to move the moving roller (24) to the upper surface of the frame, and the opening (27) is moved again to the moving port 8-. A large number of sheet metals W are left covered with C24), and by repeating the above operations, a large number of sheet metals W are stacked in an orderly manner on the pallet (G) on the sheet material support cart (26).

Also, at the same time as repeating the above operation, the lifting jack device (43) is gradually lowered, and the pallet (t) is
The height of the top sheet metal surface deposited on the top is constantly moving roller [2
4) Keep it at a constant height directly below.

Even with the above operation, the descending distance of the sheet metal dropped from above the moving roller C24) is constant, that is, the curved state in which the sheet metal is transferred while being curved is constant, and the sheet metal is piled up in an orderly manner without any displacement.

In addition, in the stocking device of the above example, the movable roller (24) moves to the side of the frame to open the opening (27) of the frame, so the height of the frame must be increased.

Place the upper surface of the moving roller [24] on another machine tool (i) (2).
If we wanted to make the table surface rla) (2a) the same as the table surface (rla) (2a), we would have to form a pit [22] as shown in Fig. 2 and install the sudock device (9) in it, but the moving roller If the structure is such that the chain (33) supporting [24] is detoured to the side, no pit is required.

That is, as shown in FIG.
Sprockets (48) (49) and intermediate sprocket [51] installed on the horizontal auxiliary frame C47) at the bottom of the frame
Turn the chain and attach the chain (52) to the sprocket (51).
) When the connected drive motor (53) is rotated, the movable roller (24) whose both ends are supported by the chain (33) moves from the top surface of the frame to the sprockets (48) and (49).
The frame (23) is moved to a detour on the side formed by the frame (23), and an opening on the top surface of the frame is exposed. The plate support cart (26) has the same structure as the previous example, but in this case, the pallet (G) receiving table (42) has an inclined surface (5) that guides the pallet (G) to an appropriate placement position.
The guide plate (54) with 4a) is the attachment.

In the process of dropping and stocking the sheet metal in warehouse i in the above example, the moving roller (24) moves from one end of the sheet metal in one direction (as shown by the arrow in FIG. 7), so the gripper (6) moves the sheet metal end. Grip is released by moving four points.

In any case, as is clear from the above description, the stocking device according to the present invention includes a large number of moving rollers that move forward and backward over an area larger than the area of the plate material, and a support that can be raised and lowered below the moving rollers. Consisting of a table and a gripper that grips the edge of the board on a moving roller, the board is gripped at the proper position by the gripper, and as the moving roller moves, it bends downward from a portion and simply falls to the receiving table placement location. Compared to the case where the material is deposited by moving it or the case where the material is deposited by sliding another board onto the board that has already been deposited,
The board materials are piled up in an orderly manner without any gaps.

Therefore, if the stocking device of the present invention is used at the connection point between the upper sheet metal processing line and the automated warehouse,
The system can be operated smoothly without any problems during receiving and receiving.

In addition, each moving roller is rotatable itself, and combined with the fact that the plate material is dropped while being curved, there is no risk of damaging the plate material.
