Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a WI specific elongation adhesive layer and a release paper that protects the surface thereof, and the release paper is formed from an independent viewing piece. #
When inspecting the adhesive layer protective paper at the time of adhesive peeling and pasting, which is peeled off in a J-like manner and supplied to the object to be pasted, it is especially important to apply the label over the surface. To attach labels to a product, a tape-shaped backing paper that is usually rolled up with a release layer interposed thereon has mainly seal-printed labels affixed to it, and a dispenser is used to sequentially apply labels one by one from the backing paper. After the label is peeled off and adsorbed and held by a label holding head, the label holding head is pressed against the surface of the target object to stick the label.

When using this method, the label can be peeled off using a relatively flexible printing machine, and the label can be pasted by pressing the 1st right corner between the objects, but it is equivalent to a mount. If the protective paper of the adhesive layer with #J delamination is cut out along with the label, the independent pressure-sensitive back shield label shown in , can be mechanically operated to remove the protective paper. This is a very difficult task for a home-based label pasting machine.

This is because in this type of label, the outer shape of the label and the outer shape of the A-paper are the same size and are punched to the same outer shape.
It is difficult to remove the label without damaging it using normal means. This is already well known, and therefore, in order to remove the protective paper manually, a part of the protective paper is cut off, and by bending the part so as to deflect it, one end of the protective paper can be removed manually. It is extremely difficult to apply the adhesive to an IJ wall automatically, and therefore we have no choice but to rely on a manual method, which reduces work efficiency and necessitates streamlining.

In view of the current situation, the present invention independently prints a protective paper and a large cut-out shape without requiring manual labor.
To provide a method that allows a piece of paper to be pasted on the surface of an article to be pasted with the protective paper separated by 1.1 cm.

That is, the present invention provides a technique for attaching a cut-out Chichige with a pressure-sensitive adhesive protective paper attached to the back side to the surface of an article using the IIJ machine. After adsorbing and holding the #I Toriden adhering head using an appropriate means, it is pressed with a clamping body from the side of the stock ivy and the paper shield, and then movable with a plurality of fixed needle rods arranged at required intervals. A group of peeling needles each having their tips aligned in a straight line is plunged into the boundary h'l< between the adhesive layer of Teijiro and the #JI peeling layer of the protective paper, After that, while removing the pressing force from the clamping body, the movable needle rod in the inserted peeling needle group is separated from the fixed needle rod, and a part of the protective paper is partially peeled off from the adhesive layer of S-Hanhei. Then, the protective paper is removed by blowing compressed air into this peeled part, and the adhesive head is used to adsorb and hold the paper.For label A, which is used for storing items, apply pressure-sensitive adhesive to the back side. A protective paper R provided with a release layer for protection is used, which is punched out in a desired shape, and as a label pasting head in the pasting device d for the label A, the following is used: A pear-type type is used in which the label is suctioned and held against the label holding surface using a vacuum operation.

The label sticking head il+, which is equipped with a suction holding function, has a label supply section that sucks and holds the front side of the label △7) on a holding surface. The desired label is placed on the label at the label supply position using a support mechanism of the required S construction, such as one that can horizontally rotate through the support arm or rotate with respect to the axis of the support arm. The opposite side is held by suction on the holding surface of the head and moved to the peeling position, and at the peeling position, as shown in FIG. Label protective paper peeling device 1 installed in

In addition, the fitting groove 114 of the machisuke piece 4 is perfectly aligned with the pivot shaft of the iI jamb 1! It is designed so that it can be smoothly engaged with and disengaged from Pin II Haruka when rotating with the entire center in place.

The fixed side slider (11) and the 0r small piece tlQ on the movable platen side made in this way have their proximal ends buried and fixed alternately on the slider side and the iJ cut side in parallel at a predetermined pitch. The needles u9i and u4 are arranged in a multi-failure tree, and these 6 needles 119
1 U4 is the needle tip, and 6 are aligned on the same plane. Therefore, in the fixed part of the needle, as shown in the third figure, one fixed side is cut out and the other side is cut so that the joining surfaces are just engaged. As a means of fixing the needle base @ part, it can be fixed by inserting it into the perforated part, or as a needle bed, it can be cast with a comparatively low melting point metal such as lead, zinc, or their alloys on the required side. There are ways to fix it.

Furthermore, as mentioned above. The needle (
A relief part M is provided on the side of the clamping plate movable row that moves back and forth perpendicularly to the 191uJ row, by stepping a part of the N side & 11 with an appropriate width to allow the needle to enter during comfortable pressure. It is being In addition, the movement plate (l) equipped with such a mechanism is connected behind the piston rod of the hydraulic cylinder (24).
It is designed so that it can be held or released by. Note that the operation mechanism for rotating the 11 pivot pins (1 position) is not limited to the above-mentioned straight I# operation mechanism, and other mechanisms may be used. Get any without.

Further, the flow and body pressure operating cylinders of each part are configured to be operated in a predetermined order from the operating pressure supply source through a control device.

According to such a specific example device, one label A is sucked and held on the holding surface (2) of the label binding head +11 at the label dispensing position to reach the peeling position, and the label binding head +11 is removed at a predetermined position. (The head (1) is stopped at a fixed position by a stopper attached to the peeling device in advance).When this stop is received, the cutting machine (10 operation fluid When the pressure-actuated cylinder is made and the piston rod moves forward, the first part of the pth is the pivot pin 11.

When the peeling of the protective paper R is completed by this operation, the label A with the protective paper removed is attached to the label, and is adsorbed and held on the holding surface (2) of the rad 11) to the next label binding operation position. Move and attach the label to the target item. The separated protective paper A' is placed in such a way that the positional relationship between the label holding surface of the label binding head and the sandwiching plate in front of #lI#F is horizontal (the label sandwiching surfaces of both are on top of each other or in a state close to that). ), the protective paper will fall and be removed at the same time as it is peeled off, and when the label sticking head holding surface is facing downwards, the protective paper will fall and be ejected automatically by the backward movement of the board. Ru. In addition, when the holding surface of the label sticking head is facing upward, a suction mechanism that temporarily holds the protective paper is inserted into the clamping plate, and the peeled protective paper is temporarily held until the label sticking head moves, and the required time is It can be discharged by removing the temporary holding force after the lapse of time. Therefore, the means for removing the protective paper may be arbitrarily set depending on the movement conditions of the label sticking head.

When the protective paper peeling operation is completed in this way, each of the fluid pressure actuated cylinders t141, 1231, and 1241 operates in reverse, and the slider (18) and the retractable piece n8i retreat all at once, returning to the original position 1d. , 口I' ItJ i 1 The country also moves backward around the support shaft bin 11@, and presents a shape corresponding to the next operation.Also, the dimensions of the clamping plate will change depending on the shape of the lapeno L6o. In the case of a single large bowl, if a suitable section of the center is held between the two, the interstitial operation using the needle will be performed at the center, and the airflow will move from this center toward both ends. There is no problem as the spacing action progresses.

As described above, according to the present invention, in a core sheet pasting machine that accommodates a punched coffin layer together with a pre-adhesive layer protective paper,
The A4 ratio was held in the adhesive head, and by skillfully using a needle and compressed air, the protective paper with delamination was separated from the adhesive by mechanical force. In addition, the protective paper could be completely removed automatically by the airflow, allowing the work to be carried out efficiently and rationally.

According to the spirit of the present invention, the present invention is not limited to the above-mentioned example of a community, and it goes without saying that the implementation of the present invention also falls within the technical scope of the present invention.
