Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the peeling mechanism of a gluing device.

Conventionally, there is a well-known glue cutting device that supplies glue in a dry state onto a board, transfers the glue while vacuum suctioning the glue side to a transfer belt, and then rapidly reverses and peels off the board.

Furthermore, if the vacuum adsorption device does not adsorb the glue to most of its opening O, the adsorption force will be weak and peeling will not be performed successfully.

Therefore, as shown in FIG.
A distance l is provided between the reversal start position B of the reversal position B, and the rotational speed of the peeling claw 12 of the peeling roller 9 during the peeling operation is made faster than the transfer speed of the reversal position B, so that the reversal position is moved from the start point to the reversal start position B. A pasting device has been proposed that moves from front to back over time (as the peeling progresses) to peel off as quickly as possible and increase the adsorption efficiency.

By performing the peeling operation quickly in this manner, the peeling operation is almost completed by the time the rear end of the glue passes the rear end of the vacuum suction section near the front end F of the lower transfer belt 6, thereby increasing the suction capacity. It was increasing the

Note that after the glue is peeled off, it is delivered to the lower carry-out belt 8 and carried out.

Further, the soot is transferred together with the peeling roller 9 to the soot conveying belt 13 which rotates in the direction of the arrow P and is conveyed out.

That is, in the conventional device, the above-mentioned interval 1 is inevitably formed, resulting in the following problems.

Ordinary glue sticks to each other, so from point F to point B, the vacuum suction force is used to transport the glue together with no problems, but depending on the drying conditions, the glue may peel off naturally. There is also.

In this case, the glue is adsorbed between point F and point B, but as shown in Figure 5 A, the glue hangs downward and overlaps each other as shown in Figure 5, by the peeling claw. This caused damage to various parts of the equipment and worsened recovery conditions.

An object of the present invention is to provide a glue-and-glue device that solves the above-mentioned problems.

An embodiment of the present invention will be described below with reference to the drawings. In the drawing, reference numeral 1 denotes an upper transfer belt which is hung around three rollers and arranged in a triangular shape, and has a large number of suction holes 2 transparently formed on the entire surface. ing.

Reference numeral 6 denotes a lower transfer belt arranged to correspond to the rear part of the upper transfer belt 1, which is similarly hung around three rollers, and whose front end F is arranged so as to correspond approximately to the rear part of the vacuum suction device. I have to.

Reference numeral 7 denotes guide pieces fixed to both sides of the machine frame of the upper transfer belt 1, which protrude into both sides of the moving locus of the plate so as to be able to guide the plate to the peeling claw 12, which will be described later.

Reference numeral 8 denotes a lower carry-out belt disposed so as to correspond to the front part of the upper transfer belt 1, and the peeled glue is delivered from the upper transfer belt 1 and carried out to the outside.

Reference numeral 9 denotes a peeling roller at one end of the left and right sides, which is mounted on a shaft 10 so as to be able to rotate intermittently by half a rotation below the upper transfer belt 1 in accordance with the glue peeling position B, and has peeling recesses at 180° intervals on its outer periphery. 11 is cut out, and when the roller 9 is at rest, one of the peeling recesses 11 corresponds to the peeling position B.

Reference numeral 12 denotes a peeling claw disposed between both peeling rollers 9 immediately behind the peeling recess 11 in the rotating direction (arrow P),
It has a function of hooking the front end of the sheet and inverting it at an acute angle along the peeling roller 9.

Reference numeral 13 denotes a delivery belt that is hung around three rollers so as to rotate along the front part of the peeling roller 9.

Reference numeral 14 denotes a bracket fixed to the machine frame on both sides of the peeling roller 9, and a roller bearing 15 supporting the front end of the lower transfer belt 6 is supported at the rear thereof.

Reference numeral 16 indicates the entire support device installed inside the rear part of the bracket 14, reference numeral 17 indicates a support tube fixed to the bracket 14, and reference numeral 18 indicates a pair of upper and lower bearings 1 for the support tube 17.
The support shaft is rotatably supported via a support shaft 9, and a movable support member 20 having a substantially S-shape is protruded inwardly and forwardly from the head at the upper end of the support shaft.

Reference numeral 21 denotes a regulating cylinder fixed to the downwardly projecting end of the support shaft 18 with a screw 22, and has a spring rod 23 and a stopper 24 projecting outward so as to form an obtuse angle with each other.

Reference numeral 25 denotes a spring that is elastically loaded between a part of the bracket 14 and the spring hanging rod 23, and is used to move the movable support member 20 inward (frontward).
It is energized to rotate.

Note that the stopper 24 is in a natural state when the bracket 1 is
It is locked on the 4th side.

Next, to explain the operation of the glue-and-glue device configured as above, the glue is applied to the upper surface and the dried N is supplied between the upper transfer belt 1 and the lower transfer belt 6 from the left side of Fig. 1. Ru.

When the front end of the strip N reaches the suction opening 0 of the vacuum suction device 3, the glue is absorbed through the suction hole 2, so even if the strip coupled with the glue moves forward from the lower transfer belt 6. It moves forward together with the upper transfer belt 1, reaches the guide piece 7, and its front end is bent downward to reach the peeling recess 1 of the peeling roller 9.
Enter 1.

Then, the peeling roller 9 rotates half a rotation, and at this time, the peeling claw 12 immediately behind the peeling recess 11 hooks the front end of the scraper and rotates in the direction of the arrow P to deliver the scrap to the carry-out belt 13.

At this time, the chair is suddenly bent in the opposite direction, so
The adhesive is successfully peeled off from the glue adsorbed to the upper transfer belt 1 by the vacuum suction device 3.

The glue is transferred to the lower carry-out belt 8 at the front part of the upper transfer belt 1 and carried forward.

Now, if the glue and glue are applied to the peeling machine while being attached to each other, it will work as described above, but if they are separated or even if they are not separated, they will be fed into the machine and the back end of the glass will be removed. A gluing device of the type in which the peeling operation is performed after applying a brake to the chisel and stretching the sheet to separate the glue to a certain extent operates as follows.

That is, when the supplied glue leaves the front end F of the lower transfer belt 6, it tends to fall downward under its own weight (the glue is attracted to the upper transfer belt 1).

), it is supported by the movable support member 20 of the support device 16 which is protruded directly below the normal moving direction of the glass on both the left and right sides, and is pushed forward from behind without falling, and is pushed forward from the rear (
If the glue is attached), attach guide piece 7.
is guided to the lower peeling recess 11, and is rapidly reversed to start the peeling operation.

However, since the rotational circumferential speed of the peeling roller 9 is faster than the feeding speed of the upper transfer belt 1, the reversal position of the tray shifts backward as the peeling operation progresses.

In this case, the movable support member 20 is pushed by the inverted position of the frame and rotates backward (outward) against the repulsive force of the spring 25 to follow the movement of the inverted position.

Therefore, by the time the rear end of the glue passes the rear end of the suction opening 0 of the vacuum suction device, all of the glue has been peeled off and the movable support member 2
0 moves to the side of the movement trajectory of the chest of drawers and then returns to its original position by the spring 25.

In this way, the present invention provides a movable support member 20 capable of supporting the strip between the front end F of the lower transfer belt 6 and the peeling start position B (the upper end position of the peeling roller 9), and the movable support member 20 is provided between the front end F of the lower transfer belt 6 and the peeling start position B (the upper end position of the peeling roller 9). Since the movable support member 20 is mounted so as to be able to move back and forth so as to be able to follow the movement, there is a great effect that the peeling operation can be performed without any trouble even when the glue is partially separated.

In particular, in the embodiment described above, the movable support member 20 rotatably supports the base end inside the machine frame on both sides of the peeling roller 9, and rotates backward (outward) as the reversing position of the slide moves backward. Because of this structure, the structure is extremely simple, there are few failures, and the assembly is easy.

However, the present invention is not limited to the above-mentioned embodiments, and as long as it is a member that can move back and forth between FBs and has a structure that can follow the backward movement of the reverse position of the chair,
It doesn't matter what kind of structure it has.

For example, a structure may be used in which a plate-shaped member 26 is biased forward by a spring (not shown) so as to be movable back and forth, as shown by the two-dot chain line in FIG.
