Description

[Detailed Description of the Invention] This invention relates to a long material pasting device used when manufacturing decorative edges for picture frames by pasting together long materials.

The so-called decorative border is manufactured, for example, by the procedure shown in FIG. That is, a synthetic resin sheet (such as a PVC sheet) as shown in FIG.
After cutting into a long base material 1 as shown in FIG. Next, the backing material 2 is pasted between the grooves as shown in d of the same figure, and the base material is bent along the grooves to obtain a decorative edge as shown in e of the same figure. As can be seen from this example, the backing material 2 must be correctly attached to the predetermined position of the base material 1 (in this example, between the grooves), but since both the base material and the backing material are long materials, It was quite difficult to bond the two together while maintaining their mutual positional relationship correctly, and it was not possible to do this efficiently.

This idea was developed in view of these circumstances, and provides a laminating device that can efficiently bond a long base material with longitudinal grooves and a backing material while maintaining the correct positional relationship. It is intended to.

An embodiment of the present invention will be described below based on the drawings.

In the figure, the laminating device for long materials includes a material conveying means for conveying the base material 1, a longitudinal positioning device, and a flanged roll 30 located on the downstream side of the device. Attach material 2. Base material 1
As shown in FIG. 3, two grooves 3 are formed in the longitudinal direction, and the backing material 2 is laminated along the grooves 3.

In this example, the material conveyance means is a roller conveyor 10.
The long base material 1 can be conveyed vertically with the grooves 3 facing upward, and an adhesive 11 is applied between the grooves 3.

The longitudinal positioning device is a roller conveyor 10
A backing material holder 2 arranged above and capable of placing the backing material 2
5, a stopper 22, a feed roller 21 for feeding out the backing material 2, and a cylinder 24 having a presser roller 23 at the lower end, and a detection device 40 for detecting the substrate 1 being conveyed by the roller conveyor 10. is attached.

The backing material holder 25 consists of two spaced apart receiving plates, and the backing material 2 is placed above the base material 1 so that the longitudinal direction is aligned and diagonally intersects with the conveyance direction with respect to the roller conveyor 10. do. Further, the receiving plate is provided with a protrusion pin for positioning the backing material 2 and can be moved up and down as a unit.

The stopper 22 is provided on a base 20 installed on the side of the roller conveyor 10, and abuts against the tip of the backing material 2 on the backing material holder 25 to prevent it from slipping down. By the way, as the backing material holder 25 is lowered, the backing material 2 is removed from the lower end of the stopper 22.

The feed roller 21 is forcibly driven and constantly rotates, and is arranged below the gap between the receiving plates. Further, it rotates so that its upper edge faces in the conveyance direction of the roller conveyor 10.

The cylinder 24 is fixed to the base 20, and the presser roller 23 is pivotally connected to a slide plate at the lower end of the rod that is guided by a guide piece of the base 20. The pressing roller 23 faces the feed roller 21 and descends due to the extension of the cylinder 24, presses the backing material 2, and lowers the backing material holder 25.
The backing material 2 is brought into contact with the feed roller 21 and sandwiched therebetween.

In addition, as the backing material 2 descends, the stopper 2
2, it is sent out by the feed roller 21.

Note that the detection device 40 is made of a phototube, and in this example is arranged above the roller conveyor 10 slightly behind the stopper 22, detects the substrate 1, and generates a signal to operate the cylinder 24 based on the detection output.

The flanged roll 30 has flanges 32, 32 that fit into each groove 3 of the base material 1, and the flanges 32 cause the base material 1 to
is positioned in the width direction, and the backing material 2 is pressed against the base material 1 in the space between the body and the upper surface of the base material 1.

In such a configuration, when the base material 1 is conveyed by the roller conveyor, the detection device 40 detects the base material 1, and in response to the detection signal, the cylinder 24, which had been in a contracted state until then, expands and holds the backing material. The tool 25 descends and places the backing material 2 on the feed roller 21 located below. As a result, the backing material 2 comes off from below the stopper 22 and is sent forward by the forcibly driven feed roller 21. If the position of the detection device, the rotational speed of the feed roller, etc. are set appropriately, the longitudinal positional relationship between the backing material 2 and the base material 1 can be made favorable.

The cylinder 24, the backing material holder 25, and the feed roller 21 constitute a backing material supplying device for supplying the backing material 2 onto the base material 1, and this backing material supplying device is connected to the detection device 4.
0 and supplies the backing material 2,
The manner in which the backing material 2 is supplied is shown in FIGS. 2a, b, and c in sequence.

The base material 1 and the backing material 2, which are carried out in an overlapping state from the longitudinal positioning device in this manner, are passed under the flanged roll 30 disposed in front and are firmly bonded together. At this time, as shown in FIG. 3, the collar 32 partially fits into the groove 3 of the base material 1, thereby restricting the lateral movement of the base material 1. In addition, since the backing material 2 is passed through the space formed by the outer periphery of the body 31 of the flanged roll, the side wall of the collar 32, and the surface of the base material 1, lateral movement is similarly restricted, and eventually the backing material 2 and the base material 1 in the width direction. If the collar 32 of the collar roll has a V-shaped cross section as shown in FIG. 3, the tip of the backing material can be successfully introduced into the space along the slope of the collar side wall. preferable.

In the above example, the case where the base material has two grooves is described, but even if there is only one groove, the backing material has two grooves.
It is clear that positioning can be performed in the same way if an external force is applied to the collar fitted in the groove.
It is extremely efficient because the materials are fed one after another by the conveying device.

As explained above, the long material laminating device according to this invention comprises a material conveying means, a longitudinal positioning device, and a flange roll having a flange projecting on the outer periphery of the body. A device for laminating and pasting a long base material with grooves and a long backing material, in which the flanges of the flanged roll are partially fitted into the grooves of the base material. By passing the backing material on the base material through the space formed by the outer periphery of the body of the flanged roll, the side wall of the collar, and the surface of the base material, the backing material is conveyed in an overlapping state through a longitudinal positioning device. Since the base material and the backing material are positioned in the width direction, it is possible to efficiently bond the base material and the backing material while maintaining the correct positional relationship.
