Abstract

PURPOSE:To provide feed without any slippage and prevent adhesives from deflection and scar by cutting parting paper portion of a coiled double-sided adhesive tape with a rotary feed circular saw having a ratchet gear and paired rotatable gear to automatically apply said tape with a transfer roller. CONSTITUTION:A predetermined length of a double-sided adhesive tape is withdrawn from a coil 17 by the operation of gears 8, 9 to a state of a strip of double-sided adhesive tape 18. An adhesive piece A1 at the leading end is attached to a transfer roll 15 having adhesion larger than that of a parting paper of said tape and stopped after extruded by an operative dimension. The adhesive piece A1 is peeled from the parting paper and transferred to the transfer roll 15. Next, the roll 15 having the adhesive piece A1 attached moves away from another section of the adhesive piece A1 and a cut-off head 15 to the applying position to contact a substance B to be bonded, and while rotating, exfoliate the adhesive piece A1 on the surface by the adhesion of said substance B. In this step, the automaic application is completed, while a rotatable circular saw 14 is operated to cut off the next adhesive piece A2 without any deflection and scar.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an automated system for extracting adhesive pieces from double-sided adhesive tape as an adhesive material and applying them to objects to be adhered. A mechanism that pulls out the double-sided adhesive tape wound into a shape in units of predetermined length, and a mechanism that cuts only the adhesive part in each unit.
It consists of a mechanism that takes out the adhesive piece and attaches it to the object to be adhered. When using double-sided adhesive tape, sizing, cutting, taking out, pasting, etc. have traditionally been done manually, but the present invention provides an apparatus that solves these problems. .

In order to solve these problems, in the present invention, the release paper part of the double-sided adhesive tape wound into a coil is able to be accurately dimensionally fed without slipping using a gear with a ratchet structure and a freely rotating gear. possible, and the adhesive part is
By using a freely rotatable round blade, the phenomenon of cutting and twisting of the adhesive pieces can be eliminated, and the adhesive pieces can be taken out and further pasted depending on the shape of the transfer roll and head. Hereinafter, one embodiment will be described in detail with reference to the drawings.

(Figure 1, (1) is the drive starter, (2) is the gear directly connected to (1) K, and (3) is the gear directly connected to (1))
, (4) is a gear corresponding to (2), and (5) is a sprocket corresponding to (3)K. The gear (4) has a stroke adjustment pin on its side surface, through which the crank arm αQ is attached. There is a movable plate (7) at the tip of the crank arm (G), which is pulled by the diameter of the stroke adjustment pin in circular rotation.
Rotate the ratchet gear (6). The gear (9) is coaxial and integral with the ratchet gear, and operates in a unidirectional rotation structure. Also, the gear (8) is the gear (9
) is a freely rotating gear synchronized with the gear (8).
) (9) is designed to sandwich the release paper at the meshing part of the teeth. There is a gear (b) at the tip of the crank arm αη, and in combination with the gear (to) etc., the freely rotatable round blade c14 is caused to make intermittent reciprocating motion. In this case, the intermittent conquest movement is one in which one cycle is an outbound journey and the next cycle is a return journey. The transfer roll (G), which has a one-way rotating structure, is used to peel off the double-sided adhesive tape and apply it to the object to be adhered, and its surface area is reduced and at the same time its shape is unique. The head aQ is a complement to the transfer roll (g), and its corners are made to match the shape of the transfer roll. Note that a heater may be installed on the transfer roll (g) and the head aQ. If the adhesive is prone to aging due to surrounding conditions and usage conditions, the transfer roll (
(b)) It dries minute amounts of moisture that naturally adheres to the surface of the product.

Figure 2 It represents the starting position in the operating cycle of the device of the present invention.

In the figure, an adhesive piece (A1) is obtained with light, but this is
Freely rotating round blade α according to the previous operation cycle.
◆ is the one obtained by cutting. The tip of the adhesive piece (A1) is located at the corner of the head αQ, and the transfer roll 4 is stopped at a position facing the head αe and sandwiching the adhesive piece (A1).

With the exception of the freely rotatable round blade α in Figure 3, the blades operate as shown by the arrows in the figure, and the double-sided adhesive tape is moved from its coil (b) to a predetermined position by the action of gears (8) and (9). The length of the double-sided adhesive tape (2) is pulled out, and the adhesive piece (A1) at the tip is transferred to the transfer roll (6) K, which has stronger adhesion than the release paper of the double-sided adhesive tape. It attaches itself so that it is pushed out by the movement dimension and stops. At this stage, the adhesive piece (A1) is peeled off from the release paper and transferred to a transfer roll (K).

Figure 4: Transfer roll (g) after the adhesive piece (AI) has been transferred to prevent adhesion
is separated from the other cut end of the adhesive piece (A1), separated from the head α, and moved to the application position. During this separation movement, the transfer roll (
G) has a unidirectional rotation structure as described above, so reverse peeling of the adhered adhesive piece does not occur.

FIG. 5 The transfer roll (2) that has obtained the prescribed adhesive piece (A1) contacts the article to be adhered (B) K, which is being sent as shown in the figure, and rotates in a predetermined direction. The adhesive piece (A1) on the surface is peeled off by the adhesive strength of B). At this stage, pasting is completed, but at the same time as this operation is completed, the freely rotating round blade α◆ operates and the next adhesive piece (A) shown in the figure is moved.
2) is obtained. Further, when the pasting operation is completed, the transfer roll 0→ returns to the position shown in FIG. 2, and thereafter continues to operate with the operations from FIG. 2 to FIG. 5 as one cycle.

As described above, the outhouse paper part of the double-sided adhesive tape wound into a coil is made to have a precise and accurate position without slippage by means of a gear (9) with a ratchet structure and a freely rotating gear (8) synchronized with the gear (9). Removes the cause of adhesive cutting accidents using the feed and freely rotating round blade A4, and removes and pastes adhesive pieces (Al, ) according to the shape of the transfer roll and head (IQ). And so.
