Furthermore, the separation of both layers is promoted and assisted by blowing compressed air in between the lifted portion of the thin sheet material P' and the next layer of the thin sheet material P'' with a side air nozzle 5, by which thin sheet material P can be surely taken out sheet by sheet without causing any damage.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an individual removal mechanism for laminated sheet material.

More specifically, it is built into or connected to a material supply device that supplies thin sheet materials as processing materials to a processing device such as a punching machine, and the laminated thin sheet materials are individually adsorbed from the top layer by a buggy call. Regarding the ejecting mechanism,
In particular, it relates to improvements in the suction structure for mechanisms that target thin plate materials that have relatively delicate surfaces, such as racemic green sheets.

[Prior art] Conventionally, the lat mechanism for individually extracting laminated thin plate materials has been, for example, by moving the lower surfaces of the laminated thin plate materials face-to-face by vacuum suction and moving vertically on the laminated thin plate materials to remove the top layer from the laminated thin plate materials. A device is known that is equipped with a main suction cup that suctions and takes out the thin sheet material, and an auxiliary suction cup that is installed near the main suction cup and strongly suctions the uppermost layer of thin sheet material partially by vacuum.

This conventional individual take-out mechanism for laminated thin sheet materials is such that when the main suction cup takes out the top, H4 thin sheet material, the auxiliary suction cup uses partial and strong suction to remove the topmost thin sheet material from the next layer. The feature is that the main suction cup is prevented from suctioning two or more sheets of sheet material at the same time by partially lifting it up and separating it from the sheet material.

[Problems to be Solved by the Invention] In the above-described conventional laminated thin plate material individual take-out machine 114,
Since the auxiliary suction cup strongly adsorbs the thin plate material locally, when the front plate material is a relatively delicate surface such as a ceramic green sheet, the auxiliary suction cup will form suction impressions on the surface of the thin plate material. This has the problem that it can be damaged due to damage.

The present invention has been made to solve these problems, and its purpose is to
It is an object of the present invention to provide an individual take-out mechanism for laminated thin plate materials that can reliably take out one sheet at a time.

[Means for Solving the Problems] In order to achieve the object described in #i, the laminated thin plate material individual take-out mechanism according to the present invention uses a vacuum suction surface on the lower surface and moves in the vertical direction on the laminated thin plate materials. The thin plate material of the top layer is sucked and taken out from the laminated thin plate material.When the suction cup is used to suck and take out the thin plate material of the uppermost layer, the thin plate material is removed from above the top layer of thin plate material by suction. An upper air nozzle that partially blows compressed air near the edge of the uppermost layer (4), and an upper air nozzle that blows compressed air partially near the edge (4) of the top layer, and when the top layer of thin sheet material is sucked and taken out by a suction cup, the top layer is A means is adopted comprising a side air nozzle for supplying compressed air in the vicinity between the thin plate material of the first layer and the next layer of thin plate material. .

[Operation] According to the above-mentioned means, the upper air nozzle blows compressed air close to the uppermost layer of thin plate material, and the air pressure around the upper air nozzle on the uppermost layer of thin plate material is compared to atmospheric pressure. Since a negative pressure area is formed, the upper air nozzle performs a suction function similar to the auxiliary suction cup of the conventional example described above, and partially lifts and separates the top layer of front plate material from the next layer of thin sheet material. However, since compressed air is blown out from the upper air nozzle, the lifted portion of the thin plate material does not come into contact with the upper air nozzle.

For this reason, the upper air nozzle can perform the suction function without contacting and damaging the thin sheet material, and the side air nozzle also allows compressed air to flow between the lifted part of the front sheet material and the next layer of thin sheet material. Since the separation between the two layers is promoted and assisted by the spraying, the object of providing an individual removal mechanism for laminated sheet material that can reliably take out one sheet at a time without damaging the sheet materials is achieved.

[Example 1] Hereinafter, an example of the mechanism for individually taking out laminated thin plate materials according to the present invention will be described with reference to the drawings.

In this embodiment, as shown in FIGS. 1 and 2, a suction cup 3. It is composed of an upper air nozzle 4 and a fixedly installed side air nozzle 5.

The suction cup 3 has a suction surface 31 having a porous structure, a mesh structure, etc. on the lower surface, and a comb hose 32 connected to the suction surface 31 and connected to a vacuum pump (not shown) is connected and fixed on the upper surface side. There is. This suction cup 3 is connected to one air cylinder via a support frame 6 fixed to its upper surface.

This air cylinder is a mounting table 7 on which the thin plate material P is laminated.
Take it downward to the arm plate 8 provided above J1
The support frame 6 is fixed to the tip of the rod 11, 12. The operating range of this air cylinder is the suction cup 3
The suction surface 31 of the thin plate material P'' of the uppermost layer of the thin plate material P stacked on the mounting table 7 is brought into contact with the uppermost layer of the thin plate material P'', or is set in a range where it is pulled up to a certain height.

The upper air nozzle 4 has a blow hole 41 formed at its lower end, and an air supply hose 42 connected to an F supply pump (not shown) for supplying compressed air is connected and fixed to its upper end. This upper air nozzle 4 is connected to the other air cylinder 2 via a support plate 9 attached to its midway portion. This air cylinder 2 is fixed vertically at the edge of the support frame 6 of the suction cup 3 (the part located near the edge of the thin plate material P stacked on the mounting table 7). a3
The support plate 9 is fixed to the tips of the rods 21 and 22. The operating range of this air cylinder 2 is the blowing of the upper air nozzle 4 (t 4
- is set between the boxes so that the hole 41 is brought close to the edge of the uppermost layer of thin plate material P' without contacting it or pulled up to a certain height. In addition, the support plate 1) has a (long hole-shaped mounting hole 9).
A plurality of holes are formed in parallel in the thin plate material 11. A plurality of upper air nozzles 4 can be installed at arbitrary intervals depending on the width of the serration of P, the material, etc. Note that the air supply pump is preferably one that can supply pulsed air.

The side air nozzle 5 has a blow hole 51 formed at its tip, and an air supply hose 52 connected to an air supply pump (not shown) for supplying compressed air is connected and fixed to its rear end. This side air nozzle 4 has its spray hole 51 connected to the top layer of the thin plate material P′ of the thin plate material P stacked on the mounting table 7.
and the next layer of thin plate material P′°,
Preferably, a number corresponding to -1 part air nozzles 4 is fixedly installed on a suitable fixing part 4; 1B on the side of the mounting table 7 near the upper air nozzle 4.

In addition, if the above-mentioned mounting stand 7 is equipped with the structure 71~a3,
The top layer of thin plate material P' can be maintained at a constant height.

According to this J:Una embodiment, the operation is performed as follows.

First, as shown in FIG. 3(A), one air cylinder 1 is driven while compressed air is blown from the side air nozzle 5 to lower the suction cup 3, and as shown in FIG. 3(B). In this way, the suction surface 31 of the suction cup 3 is brought into contact with the top layer of the thin plate material I'3IP' of the thin plate material Fil P stacked on the mounting table 7.

Next, in the state shown in FIG. 3(B), the other air cylinder 2 is driven to lower the upper air nozzle 4, and the upper air nozzle 4 is lowered.
The spraying brings the holes 41 close to the edge of the top layer of sheet material P'. According to this operation, the compressed air blown from the upper air nozzle 4 from the hole 41 initially pushes the uppermost layer of thin plate material P' toward the next layer of thin plate material F3IP'', but Thin plate material P' in which the spraying hole 41 is the top layer
As the air approaches the air, a rapid change in flow direction is forced and a negative pressure area is formed around the spray hole 41 compared to the surrounding atmospheric pressure, creating an adsorption force. This suction nozzle will be more effective if the compressed air blown from the blowing hole 41 of the upper nozzle 4 is pulsed air. In the case of particles with fine pores flowing to the right, the upper air nozzle should be blown (
A part of the compressed air blown from the J hole 41 passes through the thin plate material P' of the top layer, collides with and repels the thin plate material P'' of the next layer, and the thin plate 441'4P' of the top layer. Therefore, as shown in Figure 3 (C),
The vicinity of the edge of the top layer thin plate material P' is partially lifted from the next layer thin plate material IP''. Since compressed air is blown through the blowing hole 41, the thin plate material ypAP' of the uppermost layer does not come into contact with it and is not damaged by suction impressions or the like.

Furthermore, compressed air is sprayed from the side air nozzle 5 in the state shown in FIG. Compressed air will be blown to promote or assist the separation of the two.

The uppermost layer of thin plate material P' is adsorbed by surface and adsorption IA3, and one of the air cylinders 1 is driven to bring the J: sea urchin suction cup 3 shown in FIG. 3(D) upward. According to this operation, since the vicinity of the edge of the thin plate material P' in the top layer is partially lifted and separated from the thin plate material P''' in the next layer, it is ensured that only the thin plate feed P' in the top layer is adsorbed. It is adsorbed to the plate 3 and taken out. At this time, compressed air is sprayed from the side air nozzle 5 until the top layer thin plate material P' and the next layer thin plate material P'' are completely separated. It is preferable to continue.

In addition, the thin plate material F!I of the top layer as shown in Fig. 3 (D>
After taking out P', it is possible to move the material receiving mechanism below the suction cup 3, but if the arm plate 8 is equipped with a moving means, it is necessary to leave it as is as shown in FIG. 3 (E) 0. It is also possible to move from place to place.

The present inventor has tested the adsorption force of the hole 41 for spraying from the upper air nozzle 4, and the results will be disclosed below.

That is, when an A4 plate 0.8 mm thick ceramic green sheet was used as the thin plate material P, the dimensional structure etc. that were able to obtain an effective suction force were as follows. However, as shown in FIG. 4, for spraying, the inner diameter of the hole 41 is a, the outer diameter is b, and the spraying hole 41. If the interval between the thin plate materials P' in the top layer is C, then a:b:C is 9.0 mm: 14
．． Ou: 3.5n+m, 4.5mm + 11.
On+n+: 2, Omm, 2.0mm: 8. O

0+11+11: 7. It is Omm.

As described above, in addition to the illustrated embodiment, the suction cup 3 is driven by a motor instead of the air cylinder 2. It is also possible to provide an embodiment in which the upper air nozzle 4 moves up and down.

Further, it is also possible to support the air cylinder 2 that moves the upper air nozzle 4 up and down on a member different from the support frame 6 of the suction cup 3, or to adopt an embodiment in which the upper air nozzle 4 is moved laterally and discharges air. .

Also, the upper air nozzle 4. The operation timing of the side annostle 5 can be adjusted depending on the thickness, material, etc. of the thin plate material P.

Furthermore, by attaching a load cell to the suction cup 3, it is possible to detect the weight of the thin paulownia wood plates P taken out by the suction cup 3, and to detect and confirm whether or not the thin paulownia wood material P is taken out one by one.

[Effects of the Invention] As described above, h! according to the present invention. uFi' Since compressed air is blown between the part and the next layer of thin plate material to promote and assist the separation of the circumferential cylinders, there is an effect that the thin plate materials can be reliably taken out one by one without damaging them.

Furthermore, upper and side air nozzles #l blow compressed air.
Because it is a structural structure, there is no risk of wear unlike mechanical structures, and it has the advantage of good durability.
