Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material stacking device for stacking plate members made of metal, plastics or the like so that they can be reliably separated one after another. .

[0002]

2. Description of the Related Art Conventionally, when a plate material made of metal or plastic or a processed product thereof is stored in a warehouse or the like, it is necessary to stack these materials vertically for reasons such as area efficiency and convenience of arrangement. It was many.

[0003]

However, when they are brought into close contact with the above plate materials and stacked vertically, (1) the contact surface is in a vacuum state, (2) oil or the like may adhere,
(3) Due to factors such as generation of static electricity on each plate,
When removing the plate materials one by one, each plate material sticks to each other,
The work efficiency afterwards is extremely deteriorated.

In view of the above problems, it is an object of the present invention to provide a plate material stacking device for stacking plate materials so that they can be easily separated from each other later. To do.

[0005]

The means for solving the problem according to the present invention is, as shown in FIGS. 1 to 6, a pallet 3 on which a plurality of plate members 2 are stacked and placed, and a pallet 3 on the upper surface of the pallet 3. A thin material 5 interposed between the plate materials 2 for preventing the plate materials 2 from sticking to each other and a thin material supply means 6 for supplying the thin material 5 across the upper surface of the plate material 2 are provided. The fine material supply means 6 is
A fine material supply roller 22 that can rotate forward and backward around the horizontal axis 21 and that supplies the fine material 5 that has been wound in advance downward, and the fine material supply roller 22 reciprocates in the horizontal direction above the pallet 3. And a roller moving mechanism 24.

[0006]

In the above means for solving the problem, the roller moving mechanism 2
4, the supply roller 22 is reciprocated to move the thin material 5 into the plate material 2.
The plate materials 2 are successively stacked while being supplied to the upper surface of the.

On the other hand, at the time of taking out the plate material 2, the plate material 2 is taken out from above while winding the thin material 5.

At this time, the thin materials 5 are stacked on each of the plate materials 2
Since it is interposed between the plate members 2, it is possible to prevent the surfaces of the plate members 2 from sticking to each other.

Then, it is possible to prevent the contact surface from being in a vacuum state, and also to prevent the plate materials 2 from adhering to each other even if oil or the like adheres to the surface of the plate material 2 or static electricity is generated. be able to.

Therefore, the work efficiency can be dramatically improved when each plate 2 is removed one by one later.

In the plate material stacking apparatus having the above structure, when the plate materials are stacked, the feed roller 22 is reciprocally moved by the roller moving mechanism 24 so that the thin material 5 is traversed on the upper surface of the plate material, and the next plate material is stacked on it. When this is done, the thin material 5 is folded back across the upper surface, and the thin material 5 is interposed between the plate materials 2 each time the plate materials are stacked. The stacking operation at this time will be described in detail with reference to FIG.

First, in the preparation stage, the work switching switch 44 shown in FIG. 2 is set to the stacking mode (S1). Then, the first motor forward / reverse switching means 45 outputs a forward rotation switching signal to the first motor driving means 46 to specify the descent of the pallet 3, and at the same time outputs a second motor forward / reverse switching signal to supply the feed roller. 22 Forward rotation is designated (S2).

Next, the transport device (not shown) is started,
The plate material 2 is conveyed to the upper surface of the pallet 3 of the plate material stacking device (S3). At the same time, the operation switch 42 shown in FIG.
Turn on. Then, the timing means 43 starts timing based on the ON signal of the operation switch 42 (S4).

Then, after the plate material 2 of the first layer is placed on the upper surface of the pallet 3 of the plate material stacking device in a desired loading area (four places), the second motor is operated based on the time signal of the time measuring means 43. The drive means 48 causes the second motor 23 to rotate in the forward direction, and the fine material supply roller 22 rotates in the R direction as shown in FIG. Then, the thin material supply roller 22 can automatically supply the thin material 5 to the upper surface of the plate material 2 (S5).

9 outputs a reverse rotation switching signal to the third motor drive means 50.

The third motor driving means 50 is a time counting means 43.
The third motor 36 is reversely rotated on the basis of the clock signal of No. 3 and the reverse rotation switching signal of the third motor forward / reverse switching means 49, and the horizontal rod 35 is rotated via the toothed belt 38 and the toothed pulley 37, so that The material supply roller 22 is moved (returned) in the X2 direction (S9).

After that, the first motor driving means rotates the first motor 16 in the forward direction to move the pallet 3 by the thickness of the plate 2.
Is lowered (S10), the plate materials 2 are again stacked and placed (S11), and at the same time, the third motor forward / reverse switching means 4 is placed.
9 outputs a forward rotation switching signal to the third motor drive means 50.

Thereafter, the operations from S6 to S11 are repeated to stack the plate material 2 on the upper surface of the pallet 3.

On the other hand, at the time of taking out the plate material 2, the work switching switch 44 shown in FIG. 2 is switched to the taking-out mode (S21),
The first motor forward / reverse switching means 45 is a first motor driving means 46.
A reverse rotation switching signal is output to and the rising of the pallet 3 is designated. Further, the second motor forward / reverse switching means 47 outputs a reverse rotation switching signal to the second motor driving means 48 to specify the reverse rotation of the supply roller 22 (S22).

Then, the plate material 2 is sucked by a suction cup (not shown) of the conveying device and the plate material 2 is taken out one by one upward. At this time, the fine material supplying means 6 reversely rotates the fine material supplying roller 22 in the L direction in FIGS. 3 and 4 to wind up the fine material 5 (S23), but reverse the stacking process. Good (S24).

At this time, the thin materials 5 are stacked on each plate material 2
Since it is interposed between the plate members 2, it is possible to prevent the surfaces of the plate members 2 from sticking to each other.

By doing so, it is possible to prevent the contact surface from becoming a vacuum state, and also to prevent the plate materials 2 from adhering to each other even if oil or the like adheres to the surface of the plate material 2 or static electricity is generated. be able to.

Therefore, the work efficiency can be dramatically improved when each plate 2 is removed one by one.

(Second Embodiment) FIG. 6 is a perspective view of a plate material stacking apparatus showing a second embodiment of the present invention.

As shown in the figure, the plate material stacking apparatus of this embodiment is

The support member 31, the support cylinder 34, and the horizontal rod 35 that support the thin material supply roller 22 are the thin material supply rollers. A pair is provided on both sides of 22.

The other structure is the same as that of the first embodiment. Even in this structure, the same operation as that of the first embodiment,
It can be effective.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, in the above embodiment, the control device 41
The above described controls only the motors 16, 23, 36, but it may also control all of these in cooperation with a carrier device for carrying the plate material 2.

On the contrary, the driving of the motors 16, 23 and 36 may be manually controlled by operating the panel.
