Among these, molded ceilings are made of a skin material, a pad material, and a base material, or a skin material and a base material that are integrally polymerized. It has attracted attention and is being adopted in many vehicles.

Thus, a molded ceiling in which a skin material and a base material are directly bonded is made by polymerizing a relatively soft skin material such as a vinyl chloride film onto a hard base material such as polyethylene foam via an adhesive or the like. Further, after being processed into a desired shape in this state, the base material at a predetermined edge portion is cut and peeled off to prepare for attachment to the body.

When cutting and peeling off the edge portion of the molded ceiling, an incision is first made with a cutter at a predetermined portion of the base material, and then the base material is peeled off manually.

<Problems to be solved by the invention> However, when manually cutting and peeling the edges of a laminate such as the above-mentioned molded ceiling, the laminate has a bond between the base material and the skin material. Since they are bonded with a chemical, it is difficult to peel them off, and a lot of time and effort are required to perform the peeling process.

Further, when the cut and peeled portion of the laminate extends over a long range, the operation is particularly difficult, and it is extremely difficult to perform uniform peeling.

Further, a substantially L-shaped block 21 as a pressing body is fixed to the front end of the slide table 17, and an air cylinder 23 having a piston 22 is fixed to the upper surface of the front part thereof. A clamping plate 24 as a clamping part is connected to a fixed rod 25 via a connecting member 25'.

The approximately L-shaped block 21 has a front bulge 26 at its front lower end, and the front bulge 26 has an upper tip formed in a predetermined rounded shape and a downwardly inclined surface 27 at its lower tip. In addition, the holding plate 24 is formed so that its tip becomes gradually thinner.
The rear side surface of the tip is formed in a shape corresponding to the rounded shape of the front bulge 26 of the substantially L-shaped block 21.

A support stand 28 installed on a predetermined base (not shown) is positioned in front of the approximately L-shaped block 21, and the molded ceiling 2 as a laminate is placed on the upper surface of the support stand 28. .

The support base 28 is formed in a predetermined shape that matches the shape of the molded ceiling 2, and its front edge 29 is shorter than the end edge of the molded ceiling 2, that is, when the molded ceiling 2 is placed on it. A support base 2 whose edge rests on
It is formed to protrude from the front edge 29 of 8.

A cutter 30 and a pressing pad 31 are provided above the support stand 28 so as to be able to rise and fall freely.In particular, the cutter 30 is supported by an elevating device 32 as shown in FIG. It is arranged so as to face the upper surface of the edge of the molded ceiling 2 placed above.

Further, the lifting device 32 has an air cylinder 34 installed on the top surface of a table 33 installed at a predetermined height.
The piston 35 of the air cylinder 34 is attached to the table 33
Bracket 3 that penetrates and holds cutter 30

A stopper 39 is attached to the upper end of the guide shaft 38 to regulate the height of the cutter's elevation, and the cutter 30 is attached to the bracket 36 via bolts 40 using the plate 41, cutter 30, and... This is achieved by tightening the brackets 36 together.

In the above configuration, the air cylinders 12, 19,
and each piston 13, 20 thereof by 23,
Then, the molded ceiling 2 as a laminate is placed and set on the support stand 28 with the cutter 30 and the press pad 31 raised.

In this state, the press pad 31 is first lowered via an actuator (not shown), and the support base 2
The cutter 30 presses and supports the molded ceiling 2 on the molded ceiling 2, and then the cutter 30 descends via the air cylinder 34 of the lifting device 32, and as shown in FIG. An edge cut is made.

At this time, the cutter 30 is lowered by the air cylinder 34 of the elevating device 32, so that the stoppers 39, 39 at the ends of the guide shafts 38, 38 of the elevating device 32 are stopped by the casings of the bearings 37, 37 during the predetermined descent. 2, so that only the base material 5 of the molded ceiling 2 is reliably cut.

Next, the cutter 30 that has finished cutting the base material 5 rises again via the air cylinder 34 of the lifting device 32, and at the same time as the rising operation, the air cylinder 19 provided opposite the support base 28 is started. The air cylinder 19 extends its piston 20, receives a reaction from the end block 15 of the lift base 9, and moves the entire slide table 17 forward via the rail 14 and bearing 16.

A substantially L-shaped block 21 as a pressing body fixed to the slide table 17 is attached to a support base 28.
When the state approaches , the air cylinder 19 stops, and at the same time, the air cylinder 12 below the lift base 9 starts.

Then, the air cylinder 12 moves its piston 13
is gradually extended to raise the rear of the lift base 9, and by this operation, the approximately L-shaped block 2 fixed to the slide table 17 in front of the lift base

Then, as the substantially L-shaped block 21 gradually descends, the front bulge 26 at the tip of the block 21 is exposed to its downwardly inclined surface 2.
7, the molded ceiling 2 extending from the front edge 29 of the support base 28 is pressed, and as the molded ceiling 2 is pressed further, the base material 5 cut by the cutter 30 in the previous stage is shown in FIG. The cut portion is opened in a similar manner, and peeling begins to occur from the opening centering on the front end corner of the support base 28.

Furthermore, when the approximately L-shaped block 21 descends and the clamping plate 24 linked to the air cylinder 23 reaches the vicinity of the peeled skin material 4 of the base material 3 of the molded ceiling 2, the air cylinder tilts the lift base 9. 12 stops, and the air cylinder 23 linked to the clamping plate 24 starts instead.

Therefore, the piston 22 expands and the piston 22
The rod 25 connected to the rod 25 via the connecting member 25' is moved backward, and the clamping plate 24 fixed to the tip of the rod 25 is moved back and the tip is pushed forward toward the front bulge of the substantially L-shaped block 21. The edge of the cut opening of the base material 5 of the molded ceiling 2, which was partially peeled off in the previous stage, is pressed and held together with the substantially L-shaped block 21 while gradually approaching the section 26.

Next, in this state, the air cylinder 19 retracts its piston 20, and the entire slide table 17 is retracted through the reaction force of the end block 15 fixed to the lift base 9.

At that time, the cutting opening edge of the base material 3 is approximately L.
Since it is held between the front bulging part 26 of the letter-shaped block 21 and the holding plate 24, the base material 5 at the edge of the molded ceiling 2 is reliably peeled off simultaneously with the retreat of the slide table 17.

In this way, when the peeling of the edge of the molded ceiling 2 is completed, the cylinder 23 on the approximately L-shaped block 21 retracts its piston 22, and the base material 5 is separated by the front bulge 26 and the clamping plate 24. The clamping is released, and the air cylinder 12 retracts its piston 13 to raise the front part of the lift base 9. Finally, the pressing pad 13 that presses the molded ceiling 2 rises, and the molded ceiling 2 on the support base 28 is removed and the entire process for peeling the edges is completed.

Incidentally, it goes without saying that the embodiment of this invention is not limited to the above-mentioned embodiment.
As shown in FIG. 8, a roller 34 is fixed to a support block 21' fixed to a slide table 17 via a bracket 33, and a roller 34 is used to press the edge of the molded ceiling 2 in close proximity to the molded ceiling 2. Various other embodiments may be adopted, such as an embodiment in which the roller 34 can press with less frictional resistance when approaching the object.

<Effects of the invention> As described above, according to this invention, the quality of the processed parts and the production efficiency can be improved by basically enabling smooth and quick cutting and peeling operations on the laminate through a series of mechanical operations. The excellent effect of being able to reliably improve the performance is achieved.

That is, the front edge of the support is formed to be shorter by a predetermined length than the edge of the laminate placed on the upper surface thereof, and the pressing body is provided at the front of the support so that it can move toward and away from the front of the support through an actuator. By doing this, when the pressing body approaches the support base, the front part of the pressing body presses the edge of the laminate to ensure that the cut part of the upper layer member is opened, and the cut part of the upper layer member of the next stage is opened. This has the effect that the peeling operation can be performed smoothly.

Furthermore, since the pressing body is provided with the clamping part, it is possible to clamp the cut part of the upper layer member of the stacked body opened in the previous stage and reliably peel off the upper layer member at the same time as the actuator retreats the pressing body. The effect of being able to do this is achieved.
