Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material transfer device for sequentially stacking plate materials such as outer wall materials on a plate material transfer stage.

[0002]

2. Description of the Related Art Conventionally, there is a plate material transfer device as proposed in Japanese Patent Application No. 3-2359. As shown in FIG. 3, this conventional technique reciprocates between a plate material receiving position on the protective sheet supply stage 1 and a plate material delivering position on the plate material transfer stage 2, and a direction along the moving direction is a feed direction. And a rear end of a plate material W placed on the conveyor 3A of the slider 3 in the plate material delivery position, the slider 3 having a conveyor 3A on its upper surface and the slider 3 in the plate material delivery position. The stopper 4 is provided with a regulating member 4A that can abut against the portion.

At the plate material receiving position, however, the slider 3 receives the plate material W on the conveyor 3A from the conveying conveyor 5 in the previous step, and moves from the plate material receiving position to the plate material delivering position.
At this time, the slider 3 adsorbs the uppermost one of the protective sheets S stacked on the protective sheet supply stage 1 by the adsorption tool 3B provided on the lower surface, and the protective sheet S is moved to the plate material delivery position. It is supplied to the upper part of the uppermost one of the plate materials W previously transferred on the lower plate material transfer stage 2. Then, the slider 3 moves from the plate material delivery position to the plate material reception position in a state where the rear end of the plate material W placed on the conveyor 3A at the plate material delivery position abuts against the regulating member 4A of the stopper 4. In the process of returning and moving, the plate material W is supplied from the tip of the conveyor 3A onto the plate material transfer stage 2 below so as to be stacked on the previously transferred plate material W via the protective sheet S.

That is, the plate material W is delivered onto the plate material transfer stage 2 at the plate material transfer position, like sliding down the tip of the conveyor 3A of the slider 3.

[0005]

However, when the plate material W slides down the tip of the conveyor 3A of the slider 3 at the plate material transfer position, when the center of gravity of the plate material W moves from above the slider 3 to the plate material transfer stage 2. Then, it is momentarily supported by, for example, one roller at the tip of the conveyor 3A. At this time, the plate materials W may slide down in the direction opposite to the return movement direction of the slider 3, and the stacking positions of the plate materials W may be biased or uneven.

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible for a plate material transfer device to stably perform stacking with good alignment without causing deviations or irregularities in the stacking positions of plate materials.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a slider which reciprocates between a plate material receiving position and a plate material delivering position and which has a conveyor whose feed direction is a direction along the moving direction, and a plate material delivering device. And a stopper provided with a restricting member that can abut against the rear end portion of the plate material placed on the conveyor of the slider at the plate material delivery position. After receiving the plate material on the conveyor at the plate material receiving position and moving from the plate material receiving position to the plate material delivering position, the rear end part of the plate material placed on the conveyor at the plate material delivering position serves as a stopper regulating member. In a plate material transfer device configured to deliver the plate material from the tip of the conveyor to the plate material transfer stage below in the process of returning from the plate material transfer position to the plate material receiving position in the abutted state. Te, the front end portion of the slider, plate material paid out from the conveyor tip sliding contact is obtained by the so provided payout resistance member for applying a payout resistance the plate material.

[0008]

In the slider, a payout resistance member is provided at the front end of the slider so as to be brought into sliding contact with the plate material to be paid out from the tip of the conveyor so as to give a payout resistance to the plate material. The payout resistance member can be made of a material having a large friction coefficient with respect to the plate material, or
It can be composed of a permanent magnet or an electromagnet that can exert an attractive force on the metal plate material.

Therefore, when the plate material is delivered from the conveyor tip of the slider at the plate material delivery position, the delivery resistance member imparts a delivery resistance and does not slide down in the direction opposite to the return movement direction of the slider. That is, the plate material is pressed against the stopper regulating member, that is,
With the rear end position being regulated, the sheet is transferred to the plate material transfer stage, and the stacking position is fixed.

1 is a schematic view showing an embodiment of the present invention, FIG.
Is a schematic diagram showing a transfer procedure according to the present invention, and FIG. 3 is a schematic diagram showing a conventional example.

The plate transfer device 10 has a slider 11 and a stopper 12. In FIG. 1, 13 is a conveyor for the previous process, 14 is a protection sheet supply stage, and 15
Is a plate material transfer stage, and both stages 14 and 15 are equipped with a lifting device.

The slider 11 reciprocates between a plate material receiving position on the protective sheet supply stage 14 and a plate material delivering position on the plate material transfer stage 15, and a conveyor 11A whose feed direction is along the moving direction. Is provided on the upper surface. The slider 11 receives the plate material W from the transport conveyor 13 in the previous process at the plate material receiving position. The slider 11 is provided with a suction tool 11B on its lower surface, and can suck the uppermost one of the protective sheets S stacked on the protective sheet supply stage 14.

The stopper 12 is arranged in the upper rear part on the slider 11 in the plate material delivering position, and can abut against the rear end part of the plate material W placed on the conveyor 11A of the slider 11 in the plate material delivering position. The regulating member 12A is provided.
The stopper 12 rotates the regulating member 12A by 90 degrees and switches and sets the regulating member 12A between an open position in which it does not abut against the plate material W and a closed position in which it abuts against the plate material W.

Therefore, the slider 11 conveys the plate material W from the conveying conveyor 13 in the previous process at the plate material receiving position.
It is received on A and moved from the plate receiving position to the plate delivering position. At this time, the slider 11 adsorbs the uppermost layer of the protective sheets S stacked on the protective sheet supply stage 14 by the adsorption tool 11B provided on the lower surface, and the protective sheet S is moved to the plate material delivery position. It is supplied to the upper part of the uppermost one of the plate materials W previously transferred on the lower plate material transfer stage 15. Then, the slider 11 moves from the plate material delivery position to the plate material reception position in a state where the rear end of the plate material W placed on the conveyor 11A at the plate material delivery position abuts against the regulating member 12A of the stopper 12. In the process of returning and moving, the plate material W is supplied from the front end of the conveyor 11A onto the plate material transfer stage 15 below so as to be stacked on the previously transferred plate material W via the protective sheet S.

Here, the plate material transfer device 10 includes the slider 1
At the front end of No. 1, a sheet material W that is delivered from the tip of the conveyor 11A is in sliding contact with the sheet material W, and a sheet delivery resistance member 16 that provides sheet sheet W with sheet delivery resistance is provided. Discharge resistance member 16
Can be made of a material such as rubber having a large friction coefficient with respect to the plate material W, or can be made of a permanent magnet or an electromagnet that can exert an attractive force on the metal plate material W.

The transfer procedure of the plate material W by the plate material transfer device 10 will be described below. (1) The slider 11 is set to the plate material receiving position, and the plate material W is moved and placed on the slider 11 from the transport conveyor 13 in the previous process (see FIG. 2A).

(2) The slider 11 moves to the plate material delivery position (see FIGS. 2B and 2C). The regulating member 12A of the stopper 12 is set to the open position during the movement of the plate W, and is switched to the closed position after the movement is completed.

When the slider 11 moves from the plate material receiving position to the plate material delivering position, the suction tool 11 of the slider 11 is moved.
B sucks and conveys the protection sheet S on the protection sheet supply stage 14, and supplies the protection sheet S onto the plate material W already transferred onto the plate material transfer stage 15.

(3) Next, when the slider 11 moves back from the plate material receiving position to the plate material receiving position, as shown in FIG. 2 (D), the plate material W placed on the upper surface of the slider 11 is moved.
The movement is restricted after the time when the rear end thereof collides with the restriction member 12A of the stopper 12. This allows
When the center of gravity of the plate material W is moved above the payout resistance member 16 and above the plate material transfer stage 15, the plate material W is moved to the slider 11.
It is in a state of straddling the payout resistance member 16 and the plate material W previously transferred. At this time, since the payout resistance member 16 gives a payout resistance to the plate material W, the plate material W is constantly pressed against the regulating member 12A of the stopper 12, and the slider 11 moves further so that the slider position is above the plate material transfer stage 15. When it is completely removed from the above, it is transferred and placed on the plate material transfer stage 15 as shown in FIG.

(4) Then, when the slider 11 returns to the plate material receiving position, the stopper 12 returns to the open position,
The plate material transfer stage 15 descends by a height corresponding to the plate thickness of one plate material W.

After that, the same operation is sequentially repeated, and as a result, the plate materials W are sequentially stacked on the plate material transfer stage 15.

Next, the operation of this embodiment will be described. The plate material W is conveyed at the plate material delivery position by the conveyor 1 of the slider 11.
When the sheet material is transferred from the tip of 1A to the plate material transfer stage 15 side, it is prevented from being slid in the direction opposite to the return movement direction of the slider 11 due to the ejection resistance member 16 that imparts the ejection resistance. That is, the plate material W is discharged to the plate material transfer stage 15 while being pressed against the restriction member 12A of the stopper 12, that is, the rear end position thereof is restricted, and the stacking position is made constant.

Therefore, in the plate material transfer device 10, the stacking positions of the plate materials W can be stably performed with good alignment and without unevenness or misalignment.

[0024]

As described above, according to the present invention, in the plate material transfer device, the stacking positions of the plate materials can be stably performed with good alignment without any deviation or irregularity.
