Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking device for flat rectangular members.

[0002]

2. Description of the Related Art Conventionally, when a predetermined number of flat rectangular members arranged in parallel are stacked at a stacking position after rolling, a pair of robots provided in the vicinity of the stacking position removes each end of the flat rectangular members. A stacking apparatus is generally known in which chucking is performed at a position slightly above the stacking position, and at the same time, chucking is released to stack.

[0003]

However, in the above-mentioned conventional stacking apparatus, when the robot releases the chucking, one end of the flat rectangular member falls first and the other end hangs down. I could not stack in a neatly aligned state. Therefore, since they are put in a heat treatment furnace in an unaligned state after stacking, that is, in a disjointed state, there is a problem that they are bent or twisted after the heat treatment.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above-mentioned problems of the prior art and to provide a stacking apparatus for flat rectangular members which can be stacked in a state where the flat rectangular members are neatly aligned.

[0005]

In order to achieve the above-mentioned object, the present invention provides a stacking apparatus as described above, wherein when a flat rectangular member is conveyed to a position above a stacking position by a transfer member. A moving member that advances toward each one end of the flat rectangular member is provided near the stacking position so as to be able to move forward and backward in the length direction of the flat rectangular member, and a first actuating member that moves the movable member forward and backward is provided. Further, a chucking member for chucking each one end of the rectangular member when the moving member advances is provided on the moving member so as to be tiltable downward from a substantially horizontal position in the length direction of the rectangular member, and the chucking member is tilted. A second actuating member is provided.

[0006]

When a predetermined number of flat rectangular members are transported by the transport transfer member to the position above the stacking position, the moving member advances by the first actuating member and the chucking member provided on the moving member moves. Each one end of the flat bar is chucked at a position slightly above the stacking position. After chucking, the rectangular members drop from the other end to the stacking position by the transfer by the transfer member. At almost the same time as this drop, the chucking member is tilted downward from the substantially horizontal position by the second actuating member. As a result, each one end also falls following it and is stacked in a neatly aligned state without dripping.

An alignment plate 8 is provided on the upper surface of the carriage 6 for contacting the rear surface of the stacked flat rectangular members W, and a pusher 9 for pushing the flat rectangular members W toward the alignment plate 8.
Is movably provided. 10 is a cylinder for moving the pusher.

Reference numeral 13 denotes a traverser serving as a transfer member for transferring the flat rectangular member W, which is installed above the transfer conveyor 1 and the carriage 6 along a rail 15 provided on the upper surface of the machine frame 14 between them. A transfer fork 17 is provided on the traverser 13 so as to be able to move up and down from between the collecting levers 2 to a position slightly lower than that and an upper position of the carriage 6. In Figure 1, transfer fork
The coupling mechanism between 17 and traverser 13 is omitted.

As shown in FIG. 4, a moving member 15 is provided in the vicinity of one end of the carriage 6 by a cylinder 16 so as to be able to move back and forth in the length direction of the rectangular bar W. The rectangular member W is used as the carriage 6 for the moving member 15.
When conveyed by the traverser 13 to the position above, the chucking member 18 that advances toward each one end of the rectangular bar W and chucks each one end of the rectangular bar W is centered on the spindle 20 by the cylinder 19. Is provided so that it can be tilted downward from a substantially horizontal position indicated by a solid line in the length direction of the flat rectangular member W as indicated by a chain line. The chucking member 18 hits the lower piece 21 on which the lower surface of each one end of the rectangular bar W is placed, and the upper surface of each one end of the rectangular bar W, and cooperates with the lower piece 21 to hold the rectangular bar W for chucking. The upper piece 22 can be brought into contact with and separated from the lower piece 21 by the cylinder 23.

Reference numeral 25 in FIG. 1 denotes a payout conveyor for paying out the stacked flat rectangular members W to another process.

The operation of the above embodiment will be described. As shown in FIG. 3, the flat bar W fed on the conveyor 1 with the collecting lever 2 in the lower position slides down from the front end of the conveyor along the collecting lever 2 to the tip of the lever. They are struck and aligned one after another. Then, when the flat rectangular members W are aligned by a predetermined number, the collecting lever 2 is swung by the cylinder 3 to an upper position at substantially the same height as the conveyor 1. Gathering lever 2
After the traverser 13 has reached the upper position, the traverser 13 travels almost directly above this, and the flat rectangular members W aligned on the collecting lever 2 by the transfer fork 17 lowered slightly below the collecting lever 2. Scoop up. The traverser 13 scooping the flat bar W travels above the truck 6 stacked on the rail 15 and stops.

Next, as shown in FIG. 4, the moving member 15 is moved to the cylinder.
16 and the lower piece 21 and the upper piece of the chucking member 18 are advanced.
After putting each flat end of the rectangular bar W at 22,
The cylinder 23 is actuated to chuck the two parts 21 and 22. After chucking, the traverser 13 further travels and the transfer fork 17 retracts.
Falls from the other end to the upper surface of the dolly 6, but almost simultaneously with this fall, the operation of the cylinder 19 is released, and the chucking member 18 is tilted downward from the substantially horizontal position. Therefore, each one end of the flat bar W does not fall and follow it. After dropping, the operation of the cylinder 23 is released. Then, the cylinder 16 is released and the moving member 15 is released.
Returns to the original standby position again. Therefore, the dropped rectangular members W are stacked on the upper surface of the carriage 6 in a state of being neatly aligned. This completes one cycle of stacking.

When this stacking is completed, the cylinder 19 is operated to bring the chucking member 18 into the horizontal position again, and prepares for the next chucking of the rectangular bar W.

Flat bar W stacked on the upper surface of the bogie 6 in several steps
Is then pushed in by the pusher 9 so that the rear surface of the aligning plate 8 is in contact with the aligning plate 8. After that, the truck 6 travels along the rails 7, and in a state where it is removed from the stacking line, the worker binds the flat bar W on the truck 6 with a binding tool. After binding, the carriage 6 is moved to the original stacking position again. next,
The traverser 13 scoops the bound flat rectangular material W on the carriage 6 with the transfer fork 17, travels to a position above the payout conveyor 25, and lowers the fork 17 slightly below the conveyor 25 to remove the flat rectangular material W. Transfer to the upper surface of the conveyor 25. Then, the transferred flat rectangular material W is sent to the heat treatment furnace of the next step by the conveyor 25.

[0016]

The present invention has the above-mentioned structure,
By tilting the flat bar with one end chucked with the chucking member downward with the chucking member,
Since it is possible to drop each one end following the fall of the other end, it is possible to stack flat rectangular members in a neatly aligned state. It has an excellent effect that it will never be bent or twisted.
