DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing a pressure-sensitive adhesive coated body in which a piece to be bonded is adhered to a pressure-sensitive adhesive tape. For example, gauze in the center of the adhesive surface of the adhesive tape,
The present invention relates to a manufacturing apparatus used for manufacturing an adhesive covering such as a bandage to which a wound patch made of a nonwoven fabric or the like is stuck.

[0002]

2. Description of the Related Art Conventionally, as a manufacturing apparatus for manufacturing this kind of bandage, a band-shaped adhesive tape is intermittently fed out and transferred, and a band-shaped bonded sheet is cut and cut into a predetermined length. There is one that is stuck to an adhesive tape (conventional example 1).

A device disclosed in Japanese Patent Publication No. 3-12893 is also known (conventional example 2). The apparatus disclosed in the official gazette can manufacture an adhesive bandage while continuously supplying each raw material such as an adhesive tape to the main drum, and can improve productivity and reduce costs. .

[0004]

However, in the device of the prior art 1, since the feeding of the adhesive tape and the cutting of the wounding member as a piece to be adhered are performed intermittently, the intermittent speed is limited. There was a problem with productivity.

In the apparatus of the prior art 2, the rotation center of the main drum for sucking and transferring the adhesive tape and the suction drum for transferring the wounding member cut by the cutter drum are parallel to each other. It is provided in. Accordingly, as shown in FIG. 6, the transfer direction of the adhered sheet 101 and the transfer direction (arrow direction) of the adhesive tape 100 coincide.

[0006] For this reason, in the conventional apparatus, the damage applying member 10
1, the cutting edge 101a is located before and after in the transport direction, and the length L of the adhesive member 100 in the width W direction (in the direction perpendicular to the adhesive tape transport direction) of the adhesive member 101 is
Is determined by the width length.

[0007] A member to be scratched with respect to the width W of the adhesive tape 100
In the case where the ratio of the length L of the adhesive tape 101 is set to be constant, if the width W of the adhesive tape 100 is large, the length L of the scratching member 101 must be large.

However, since the wound-applying member 101 is manufactured in the shape of a long strip having a constant width, there is a disadvantage that the sheet to be adhered having a predetermined length in the width W direction of the adhesive tape 100 cannot be applied. In addition, the production of a plurality of widths of the sheet to be bonded requires high costs and a plurality of types of sheets to be bonded must be stored and prepared.

Accordingly, the present invention has been made to solve such a problem, and the cutting and transfer of the adhesive tape and the sheet to be adhered can be continuously performed to improve the productivity. By transferring the sheet to be pasted in the width direction of the tape, even if the sheet to be pasted has a constant width, the sheet to be pasted having a predetermined length in the width direction of the adhesive tape can be adhered to the adhesive tape. Make it an issue.

[0010]

The manufacturing apparatus according to the present embodiment has the above-described configuration. Hereinafter, a method for manufacturing a bandage using the apparatus will be described.

First, the adhesive tape raw material 1 ′ is supplied to the main drum 10 by the adhesive tape supply means 15, and the raw material release paper 21 is peeled off from the adhesive tape raw material 1 ′ by the peeling section 22. The raw material release paper 21 is taken up around a roll 26 by the recovery means 20, while the adhesive tape 1 from which the raw material release paper 21 has been peeled is transferred to the next step while being adsorbed on the main drum 10 as it is.

Next, the surface of the adhesive tape 1 from which the material release paper 21 has been peeled off,
3 is affixed.

Here, in the wound member supplying means 30, the wound member 3 is formed and supplied in the following manner. First, the strip-shaped scratching member raw material 3 ′ is continuously supplied at a constant speed toward the rotary blade 32 and the rotary transfer body 34 with the upper and lower portions sandwiched by the attached sheet feeding means 40.

When the raw material 3 'is applied between the rotary blade 32 and the rotary transfer body 34, the rotating rotary blade 32 cuts the raw material 3' to a predetermined length. The wound applying member 3 is formed. The wound applying member 3 is transferred while being attracted to the rotary transfer body 34. Here, the rotation speed of the rotary transfer member 34 is set to be higher than the feed speed of the sheet-to-be-adhered feeding means 40, and the scratching members 3 are attracted to the rotary transfer member 34 at predetermined intervals in the front-rear direction. Is done.

Further, the cutting edge 3a of the wounding member 3 held and rotated by the rotary transfer body 34 is positioned in the front-rear direction, and the length L of the wounding member 3 is Is set to a predetermined length depending on the interval. Scratch member
3 is rotated downward together with the rotary transfer body 34, and when moved above the main drum 10, the suction is released and the rotary blade 32
Air is blown out of the wound, so that
It will be attached to the center of the adhesive surface of 1. Here, the rotation center B of the rotary transfer body 34 is the rotation center A of the main drum 10.
Therefore, the scratching member 3 held by the rotary transfer body 34 is continuously supplied from a direction perpendicular to the direction of transport of the adhesive tape 1 on the main drum 10 ( (See FIG. 4).

Adhesive tape 1 to which wound applying member 3 is attached
Are product release papers 5a, 5
With the b attached, the main drum 10 is separated.

Then, the adhesive tape 1 released from the main drum 10 is peeled off the reinforcing carrier film 61 at the carrier film peeling section 60, cut into a desired shape by the die roll 71, and the scrap 81 is removed. Sampling waste
81 is removed to form the plaster body 7, and the plaster body 7 is formed.
After being stored in the upper and lower packaging sheets 9a and 9b,
Sealed by 93. Then, a perforation 9c is formed between the adjacent bandage bodies 7 by the cutter means 95,
A plurality of adhesive plasters are automatically and continuously produced (see FIG. 5).

As described above, in the manufacturing apparatus according to the present embodiment, the scratching member 3 cut to a predetermined length is placed on the adhesive tape 1 in a direction intersecting the transport direction (adhesive tape).
1 in the width direction), the continuous operation of the adhesive tape 1 and the continuous cutting and the continuous transfer of the damage applying member 3 can be performed continuously and at a high speed.

Further, after the product release papers 5a and 5b are adhered to the adhesive surface of the adhesive sheet 1 by the product release paper supply means 50, the carrier film peeling section 60 removes the backing carrier film 61 from the adhesive tape 1 by the carrier film release section 60. Because of peeling, the carrier film does not remain in the final product. Moreover, since the carrier film 61 is peeled off after the product release papers 5a and 5b are attached to the adhesive tape 1, the adhesive tape 1
Extension can be prevented.

Although the above-described embodiment has the above-mentioned advantages, the present invention is not limited to the above-described embodiment. For example, an adhesive tape constituting a part of the bandage main body 7
The shape of 1 and the damage applying member 3 can be any shape such as an elliptical shape other than the rectangular shape, and the design can be appropriately changed within a range intended by the present invention.

[0046]
