Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet pressing jig for surely taking out, one by one, flexible sheets such as stacked plastic materials.

[0002]

2. Description of the Related Art Conventionally, for example, a flexible sheet such as a laminate sheet made of plastic is attached to the interior of an instrument panel which is an interior part of an automobile, a roof, a door, etc. Sex, aesthetics in the car,
Although heat insulation and sound insulation effects have been improved, in the molding process for molding such an instrument panel, a flexible sheet is usually conveyed in a laminated form. Then, from the laminated sheets, for example, the sheets are adsorbed one by one by an adsorber, taken out, and attached to the aggregate.

[0003]

However, at the time of taking out such a sheet, there is a case where two or more sheets are stuck together and taken out although it is originally desired to take out only the uppermost one sheet. However, there is a problem in that it may occur or the work may be interrupted in the middle to reduce productivity. That is, since the flexible sheet is usually formed with irregularities such as a squeezing pattern, and these are stacked in layers, the space sandwiched between the upper and lower sheets becomes close to a vacuum state, which facilitates close contact. Or, due to the presence of oil or the like interposed between the two, a problem that two or more sheets were taken out was likely to occur. On the other hand, there is a device that lifts the stacked works one by one from the top by a suction cup and takes them out, and when the second-layer work sticks to the work, suddenly lowers the suction cup and sifts it down by reaction. Although it is known as a device such as Japanese Patent Application No. 63-50670, this device is suitable for taking out a rigid thin plate such as a steel plate sheet, and is suitable for a soft material such as a laminated sheet. Was unsuitable.

[0004]

In order to solve such a problem, the present invention provides a jig capable of surely taking out soft sheets one by one when sequentially taking out the laminated sheets stacked on the pallet. That is, a tubular member that is installed vertically and has a vertical slit groove on its side surface is provided, and a slide body that can slide up and down is provided in the cylinder of the tubular member. After mounting, the tip portion was extended to the outside through the slit groove. Then, the tip of the pressing member is brought into contact with the upper edge portion of the laminated sheet, and the laminated sheet is pressed by the own weight of the pressing member and the sliding body. Further, the holding jig is provided with a mounting portion for fixing to the side plate of the pallet so that it can be attached to and detached from the pallet.

[0005]

The upper edge of the laminated sheet is pressed by the tip of the pressing member, so that when the uppermost sheet is lifted and taken out, the edges of the second and subsequent sheets are pressed by the pressing member. Separate the two. Further, since the sliding body and the pressing member move downward by their own weight according to the height of the laminated sheet, it is possible to correspond to any height position.
Also, by making it removable from the pallet, the pallet replacement work is easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the sheet pressing jig of the present invention will be described with reference to the accompanying drawings. Figure 1 shows 3 of the sheet pressing jig.
FIG. 2 is an overall view of the supply device, and FIG. 3 is an operation view.
The holding jig of the present invention is applied to, for example, a device for supplying a flexible sheet for an instrument panel, which is an interior part of an automobile, and in the case of an embodiment, this flexible sheet W is shown in FIG.
As shown in (1), it has a laminated structure of thick foamed polypropylene Wi and the soft polypropylene Wo of the surface layer thereof, and the soft polypropylene Wo as the skin has irregularities such as a squeeze pattern to enhance the design.

When the sheets W are stacked on the pallet 10 as shown in FIG. 2 and conveyed, the sheets W are taken out one by one by the suction unit 15 of the feeding device, and the sheets are put into a pair of molds 16. After being transferred, they are superposed on the aggregate C made of an ABS material which has been shaped into a desired shape in advance and whose upper surface is coated with an adhesive, and is closely molded by, for example, a vacuum means. The holding jig 1 is used when the flexible sheet W is taken out.

That is, the holding jig 1 is provided with a cylindrical member 2 installed vertically as shown in FIG. 1, and a mounting portion 3 provided on the upper portion of the cylindrical member 2, and the mounting portion 3
Can be attached to the side plate 11 of the pallet 10 described later. The cylindrical member 2 is a hollow cylinder having a circular cross section and having a length substantially equal to the height of the side plate 11, and a slit groove 4 as shown in FIGS. It is formed in the longitudinal direction of the shaku.

A sliding body 5 is provided in the cylinder of the cylindrical member 2. The sliding body 5 has a columnar shape with an outer diameter slightly smaller than the inner diameter of the cylinder of the tubular member 2, and is adapted to slide up and down in the cylinder. In addition, a rod-shaped pressing member 6 protruding laterally from the side surface is integrally provided on the sliding body 5. The tip of the pressing member 6 is extended to the outside of the cylinder through the slit groove 4, and in the case of the embodiment, the tip is slightly bent upward to form an inverted V shape.

The mounting portion 3 on the upper side of the tubular member 2 is provided on the opposite side of the slit groove 4, and has a bracket 7 having an L-shaped cross section fixed to the side surface of the tubular member 2 and the bracket 7.
Is provided with a tightening screw 8. Then, the side plate 11 of the pallet 10 is sandwiched and fixed by the tightening screw 8 and the tubular member 2.

On the other hand, the pallet 10 is formed in a box shape by providing a side plate 11 around a bottom plate 12 which is slightly larger than the shape of the flexible sheet W, and can form a space around the stacked laminated sheets. I am trying. The bottom plate 12 has a lower surface provided with a pair of leg portions 13 each having a hole into which a claw of a forklift is inserted.

The operation of the sheet pressing jig 1 configured as described above will be described. In the step of adhering the flexible sheet W and the aggregate C, when the pallet 10 on which the laminated sheets are mounted is conveyed by a forklift or the like, the worker attaches the holding jig 1 to the side plate 11 of the pallet 10. At this time, the sliding body 5 in the tubular member 2 is moved upward so that the tip of the pressing member 6 is located at the uppermost stage of the laminated sheet.

For this reason, when the attachment is completed, the leading end of the pressing member 6 comes into contact with the upper edge of the laminated sheet and is pressed down from above by its own weight. Further, as is clear from FIG. 1B, the sliding member 5 is in a slightly tilted posture in the cylinder, and therefore the holding member 6 is also in a posture in which the leading end is lowered. Can be clamped horizontally. Needless to say, the shape of the tip may be a straight line.

When the holding jig 1 is set in such a state, the suction unit 15 takes out.
That is, the suction portion 15a descends to adsorb the uppermost sheet W and ascends. At this time, as shown in FIG. 3, when the sheet W of the next stage is also lifted,
The tip of the pressing member 6 prevents this. That is, since the upper sheet W is strongly pulled upward by the suction portion 15a, even if the tip of the pressing member 6 is hooked to the edge, the edge sheet is bent and lifted up as it is, but the next sheet W is higher than the upper sheet W. Since it is only lightly adhered,
When the tip of the pressing member 6 is hooked on the edge portion, it is peeled off before the edge portion is bent.

In this way, the sheets W are surely taken out one by one and transferred to the contacting step. At this time, as shown in FIG. 4, air injection by the air nozzle 17 may be used together. That is, when the pressing member 6 is hooked on the edge of the next-stage sheet W, the air can be blown between the upper and lower sheets W to separate the sheets W more effectively.

When the number of sheets W on the pallet 10 decreases and the stacking height of sheets decreases, the pressing member 6 descends along the slit groove 4 by its own weight and always presses the uppermost sheet upper edge portion. Will be attached. Also, the slit groove 4
The upper and lower end portions 4a and 4b serve as stoppers for preventing the sliding body 5 and the pressing member 6 from coming off in the tubular member 2 having both ends open. Instead of preventing the upper and lower ends 4a and 4b of the slit groove 4 from slipping out, both ends of the tubular member 2 may be closed, or a convex portion for preventing the sliding body 5 from slipping out is provided in the cylinder. You may

As described above, the sheet pressing jig of the present invention is particularly suitable as a jig for reliably taking out soft flexible sheets one by one, and has a simple structure and does not require facility cost. Highly useful. Further, since the work of attaching to the pallet is extremely simple and easy to handle, there is an effect that no extra effort is put on the worker.
