Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to an apparatus for removing protective paper attached to a sheet material such as an aluminum plate or a stainless steel plate.

b. Prior Art When sheet materials such as aluminum plates and stainless steel plates are laminated, they are laminated with protective paper interposed in order to protect the surfaces. Therefore, when the sheet material is separated one by one and fed to a processing machine or the like, the protective paper becomes an obstacle and must be removed.

Conventionally, the protective paper has been removed manually, but in order to save labor, a technique has been developed in which the protective paper is blown away using air. As such technology, for example,
There is Publication No. 36040 (hereinafter simply referred to as a precedent example).

c Problems to be solved by the invention In the previous example, the separation and blowing off of the protective paper on the sheet material is performed with one nozzle, so the separation and blowing off of the protective paper from the sheet material is not reliable. There is a problem that is missing.

Furthermore, in the prior art, the post-processing system tends to be extensive in order to process the protective paper into compressed paper.

d Means for solving the problem This invention was made in view of the conventional problems as mentioned above, and this invention is designed to move sheet materials loaded on a table onto a lifter installed to be able to move up and down. It is adsorbed by multiple vacuum parts.
When each sheet is lifted horizontally and separated one by one, a device is used to remove the protective paper interposed between each sheet, and at least the top sheet of the sheets stacked on the table is separated. a first air nozzle for injecting air between the protective paper on the uppermost sheet material and making the end side of the protective paper float above the sheet material; a second air nozzle for blowing air between the floating protective paper and the uppermost sheet material to blow off the protective paper; and a second air nozzle for blowing off the protective paper by blowing air between the floating protective paper and the uppermost sheet material; a comb-shaped rotary body that transfers the protected paper that has been blown off by the second air nozzle to the transport truck; a third air nozzle that blows out air in a direction that presses the protective paper blown by the second air nozzle against the comb-shaped rotary body; A fourth air nozzle is provided inside the comb-shaped rotating body to blow away the protective paper that has been pressed and transferred to the carrying-out cart from the comb-shaped rotating body, and a fourth air nozzle is installed in the comb-shaped rotating body to prevent the protective paper from getting entangled with the shaft of the comb-shaped rotating body. In order to achieve this, a comb-shaped cover plate is provided extending from the table side over the axis of the rotating body to above the fourth air nozzle.

e Effect With the above configuration, when the sheet material is sucked and lifted by the vacuum part provided in the lifter, the gap between the topmost sheet material stacked on the table and the protective paper on this sheet material is generated. Then, air is flowed in from the first air nozzle, and the edge of the protective paper floats up.

When the edge of the protective paper floats up, air is blown from the second air nozzle between the protective paper and the uppermost sheet material, and the protective paper is blown away from the sheet material toward the comb-shaped rotating body. removed.

The blown protective paper is then pressed against the comb-shaped rotary body by the air blown out from the third air nozzle, and is transported toward the delivery cart by the rotation of the comb-shaped rotary body. The protective paper transferred to the carrying-out cart is blown toward the carrying-out cart by air jetted from a fourth air nozzle provided inside the comb-shaped rotating body.

As mentioned above, when the protective paper is pressed and transferred to the comb-shaped rotary body, even if the protective paper tends to get entangled with the shaft of the rotary body, there is a fourth A comb-shaped cover plate extending above the air nozzle prevents the protective paper from getting tangled with the shaft.

f Example First, the outline of the present invention will be explained based on FIG.

FIG. 1 shows a protective paper removing device 5 attached to a single sheet conveyance device 3 for sheet materials 1 such as iron plates. Protective paper 9 between sheet materials 1
is inserted.

Although the sheet material 1 and the protective paper 9 are shown separated and horizontal in FIG. 1, this is exaggerated for the sake of clarity, and they are actually stacked closely together.

A lifter 13 equipped with a plurality of vacuum pads 11 is provided above the stacked sheet materials 1, and after the lifter 13 is lowered and the vacuum pads 11 come into contact with the sheet materials 1, the inside of the vacuum pad 11 is opened. Apply negative pressure and lift only one sheet as shown in Figure 1.

What is shown like a pillar on the right side of the figure is the first air nozzle 15, which includes the protective paper 9 and sheet material 1 of each layer.
Let air flow between.

The second air nozzle 17 provided above the first air nozzle 15 blows air onto the raised protective paper 9 on the right side and curls the protective paper 9 between it and the sheet material 1 above as shown in the figure. , it blows to the left.

The first air nozzle 15 and the second air nozzle 17 in this case are an example in which pressurized air from an air pressure source 19 such as factory equipment is guided through a solenoid valve 21.

A comb-shaped rotating body 23 is located on the left side of the single-sheet unloading device 3.
is driven by a geared motor 25 and rotates in the counterclockwise direction in the figure, and in the upper right corner, an appropriate number of third air nozzles 27 apply air pressure in the direction of pressing the blown protective paper 9 against the comb-shaped rotating body 23. is added.

A fourth air nozzle 29 is provided at the lower left position of the comb-shaped rotating body 23 in the figure.
The protective paper 9, which has been moved by being pressed against the paper 3, is blown away onto the delivery cart 31.

FIG. 2 is the same elevational view as FIG. 1, but shows the longest and highest sheet materials 1, such as iron plates, that can be stacked on the table 7. In addition, a slat conveyor 33 (slatted conveyor) receives one sheet material 1 and transfers it to the right.
The shaft positions 35 of the four corner sprockets, the drive motor 37, and the horizontal transfer pass line PL are shown.

In the plan view of FIG. 2 shown in FIG. 3, an example is shown in which the first air nozzle 15 described above is also provided on the other side of the sheet material 1, and three sets of second air nozzles 17 are also provided. It has been shown that there is.

4 and 5 are diagrams showing the comb-shaped rotating body 23 in detail. The comb-shaped rotating body 23 may be constructed by assembling ring-shaped wire brushes at regular intervals, and between the teeth of each comb there is a A cover plate 39 is provided extending from the right side over the shaft to above the fourth air nozzle 29 to prevent the protective paper 9 from getting entangled with the shaft.

The operation of this embodiment is only when there is a protective paper on the top surface of the sheet materials stacked on the table, since there is no sheet material above that serves as a ceiling, it must be removed manually, but after that, it must be removed one after another. The explanation of how the protective paper is automatically removed will be omitted as it would be redundant.

g. Effect of the invention As can be understood from the explanation of the above-mentioned example, this invention basically allows the sheet material 1 loaded on the table 7 to be moved up and down by a plurality of lifters 13 equipped with When the sheet materials 1 are separated one by one by suction by the vacuum pad 11 and horizontally lifted one by one, a device is used to remove the protective paper 9 interposed between each sheet material 1, and the device is placed on the table 7. Air is flowed between at least the uppermost sheet material 1 of the stacked sheet materials 1 and the protective paper 9 on this uppermost sheet material 1, so that the end side of the protective paper 9 floats above the sheet material 1. a first air nozzle 15 for blowing off the protective paper 9 by blowing air between the protective paper 9 whose end side has been floated by the first air nozzle 15 and the uppermost sheet material 1; a second air nozzle 17; a comb-shaped rotating body 23 on one side of the table 7 that transfers the protective paper 9 blown off by the second air nozzle 17 to the delivery cart 31; and the second air nozzle 17. a third air nozzle 27 that blows out air in a direction that presses the protective paper 9 blown away by the comb-shaped rotary body 23 against the comb-shaped rotary body 23;
A fourth air nozzle 29 is provided inside the comb-shaped rotary body 23 to blow away the protective paper 9 transferred to the side from the comb-shaped rotary body 23 to the carry-out cart 31, and the protective paper 9 is entangled with the shaft of the comb-shaped rotary body 33. To prevent this, the rotating body 23 is removed from the table 7 side.

With the above configuration, in the present invention, when the sheet material 1 is sucked and lifted by the vacuum pad 11 provided in the lifter 13, the uppermost sheet material stacked on the table 7 and this sheet material are separated. Air is flowed from the first air nozzle 15 between the upper protective paper 9 and the edge of the protective paper 9 to float.

When the edge of the protective paper 9 floats up, air is blown from the second air nozzle 17 between the protective paper 9 and the uppermost sheet material 1, and the protective paper 9
It is blown away from above in the direction of the comb-shaped rotating body 23.

The blown protective paper 9 is then moved to the comb-shaped rotating body 2 by the air blown out from the third air nozzle 27.
3 and is transferred in the direction of the unloading cart 31 by the rotation of the comb-shaped rotating body 23,
The protective paper 9 transferred to the carry-out carriage 31 side is blown toward the carry-out carriage 31 by air jetted from the fourth air nozzle 29 provided in the comb-shaped rotating body 23.

As mentioned above, when the protective paper 9 is pressed and transferred to the comb-shaped rotary body 23, even if the protective paper 9 tends to get entangled with the shaft of the rotary body 23, the rotary body 23 is not exposed to the shaft from the table 7 side. Since a comb-shaped cover plate 39 is provided that extends above the fourth air nozzle 29, the protective paper 9 will not become entangled with the shaft.

That is, according to the present invention, the protective paper 9 attached to the sheet material 1 can be reliably removed, and the removed protective paper 9 can be reliably conveyed to the cart 31.
