Description

[Detailed description of the invention] This invention separates loaded plates (workpieces) in the supply and discharge device (loading/unloading) for plate-shaped materials, and makes it possible to reliably take out only one plate. The present invention relates to a plate separation device configured as described above.

Conventionally, when separating plates loaded on a stacking device and reliably taking out only one sheet, a method of separation using a magnetic levitation separating device (magnetic floater) has been generally performed.

However, in the case of a magnetic levitation separation device, the plates used must first be made of magnetic material, the edges of the loaded plates must be aligned, and if there is oil between the plates, This method had many drawbacks, such as the fact that the plates were in close contact with each other and could not be separated using a magnetic levitation separation device alone, and was also very expensive.

This invention effectively solves the problem of the conventional lack of stock, and its purpose is to inject pressurized air onto the sides of the loaded planks to separate the planks and reliably take out the planks one by one. The present invention provides a plate material separation device that can perform the following steps.

Hereinafter, a preferred embodiment of this invention will be described based on the accompanying drawings.

FIG. 1 shows a plate separation device 3 equipped with a plurality of suction devices 1 such as vacuum suction cups for adsorbing plate materials W (workpieces W).
The plurality of suction devices 1 and an injection device 7 for injecting compressed air (pressurized air) onto the side surface of the loaded plate materials W are provided.

The support frame 5 is operated by an actuating device (not shown).
The suction device 1 is configured to be movable horizontally and vertically, and is attached to the tip of a support bar 9 suspended from the lower surface of the support frame 5 .

Next, the injection device 7 is attached to one end of the support frame 5 and is configured as follows.

As shown in FIGS. 1 and 2, the injection device 7 includes a movable bar 11 that can be raised and lowered and a fixed bar 13 suspended from one end of the support frame 5 with a predetermined gap therebetween. A first air injection member 15 and a second air injection member 17 are attached to the distal ends of the movable bar 11 and the fixed bar 13, respectively.

The proximal end of the movable bar 11 to which the first air injection member 15 is attached is inserted through the guide member 19 attached to the lower surface of the support frame 5 and the guide hole 21 formed in the support frame 5, and the proximal end thereof is equipped with an adjustable stopper nut 23.
is installed.

Further, the movable bar 11 between the guide member 19 and the first air injection member 15 is interposed with an elastic member 25 such as a spring for constantly urging the movable bar 11 downward.

- A guide bar 27 is installed on the upper surface of the first air injection member 15 in parallel with the movable bar 11, and the upper end of the guide bar 27 is inserted through the support frame 5. .

Note that the guide bar 27 prevents the first air injection member 15 from rotating.

Further, a detection member 29 for detecting the height of the loaded plate materials W and a horizontal air injection port 31 are provided on the side surface of the first air injection member 15.

The detection member 29 has a detection bolt 35 that can be raised and lowered at the tip of an arm 33 that protrudes from the side wall of the first air injection member 15.
is attached, and the air injection port 31 is connected to a pressure supply source (not shown) via a pressure supply vibe 37.

The detection member 29 detects the height of the loaded plate-like material W and sets the air injection port 31 at a fixed position on the plate-like material W.

Next, the fixing bar 13 to which the second air injection member 17 is attached is fixed via a fixing nut 39 so as to be adjustable in height.

An air injection port 41 is formed diagonally upward in the second air injection member 17, and this air injection port 41 is also connected to a pressure supply source (not shown) via a pressure supply pipe 37.

Next, the operation of this embodiment constructed as described above will be explained.

First, before starting the work of separating and carrying out the loaded works W, the positions of the air injection port 31 of the first air injection member 15 and the air injection port 41 of the second air injection member 17 are set.

The position of the air injection port 31 can be adjusted by loosening the stopper nut 23 and aligning it with the height of the second or third workpiece W from the top of the loaded workpiece W.
1 is the height between the top workpiece W and the second workpiece W when the fixing nut 39 is loosened and pressure air is injected from the air injection port 31 to create a gap between the workpieces W. The adjustment is made so that only the uppermost workpiece W can be separated by injecting compressed air in between.

In the above state, the support bar 9 is lowered, and the suction device 1 is brought into contact with the upper surface of the loaded work W to adsorb it.

At this time, the tip of the detection bolt 35 of the detection member 29 hits the upper surface of the workpiece W, so the first air injection member 15 does not descend any further.

When compressed air is injected from the air injection port 31 of the first air injection member 15 in such a state, a gap is created between the works W, and the compressed air is further upwardly released from the air injection port 41 of the second air injection member 17. By injecting it, only the top loaded plate W can be separated.

Then, the work W is suctioned by the suction device 1, lifted upward, and carried out to the next process.

Note that a suction (not shown) is formed in the adsorption device 1 and communicates with a vacuum suction device (not shown).

As described above, when separating the loaded plate-like materials W, pressurized air is injected from the horizontal direction against the side surfaces of the plate-like materials W to separate the several sheets of the plate-like materials W from the top. Then, compressed air is jetted diagonally upward or diagonally downward from the air jet port 41 of the second air jetting member 17 to ensure that only the top plate material W is separated. This is what we are trying to do.

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration. A movable bar having a first air injection member at its lower end is supported in a vertically movable frame on which a vertically movable suction device is installed, and a second air injection member is vertically movable.
A fixed bar having an air injection member at its lower end is vertically disposed adjacent to the movable bar.

The air injection port provided in the first air injection member is positioned so as to always inject compressed air from the top to the several plates.

Therefore, the positioning accuracy of the first air injection member may be relatively rough.

Further, the air injection port provided in the second air injection member injects compressed air between the uppermost plate and the second plate separated by the compressed air from the air injection port of the first air injection member. The second air injection member may be positioned relatively roughly.

That is, according to the present invention, even in the case of separating relatively thin plates, the positioning accuracy of the first and second air injection members may be relatively rough; Since the plates are separated in three stages by the compressed air injected from the plate, changes in the thickness of the plates can be easily dealt with, and the plates can be separated reliably.

It should be noted that this invention is not limited to the above-mentioned embodiments, and may be implemented in other embodiments.
