Description

[Detailed Description of the Invention] Industrial Field of Application: The present invention is characterized in that when applying a bulge to a base cloth, the bulge is evenly distributed in each part and each non-pump agent line is formed orthogonally to each other. This relates to a manufacturing device for pads.

Conventional technology: Patches are manufactured using a two-step process of applying a patch to a base cloth and attaching a cover film to the surface of the patch, either consecutively or simultaneously. As shown in the figure, a plaster feeder 2 is installed above the coating roll 1, a base sheet 5 is passed between the coating roll 1 and the plaster feeder 2, and the coating thickness is adjusted by a doctor 3 attached to the plaster feeder. While adjusting, the plaster 7 is applied to the upper surface of the base sheet 5, and then the cover film 6 is wound and guided to the film rolls 4, 4' to be supplied, and the cover film 6 is attached to the surface of the plaster 7 to obtain the plaster 10. It is being

Problems to be Solved by the Invention: When using the conventional technique as described above, the plaster 7 settles from the plaster feeder 2 onto the base cloth 5, and the excess is scraped off according to the set position of the doctor 3. Since the amount corresponding to the required thickness is applied to the base cloth 5, the base cloth 5 is not press-fitted into the structure of the base cloth 5. Further, since no additional pressure is applied to the applied plaster 5, many air bubbles are mixed into the viscous paste 5 due to air entrainment, which causes the cover film to be removed by subsequent film rolls 4, 4'. There was a problem in that even the spreading pressure applied at the time of applying 6 did not eliminate the air bubbles, and the lack of a function to level out fluctuations in the supply of the poultice 7 caused variations in the coating thickness. Furthermore, when cutting the pad 10 to which the cover film 6 and the base cloth 5 are attached on the front and back sides in the direction in which the pad 10 migrates during manufacturing and in the direction orthogonal to this transition direction, the cut Another problem was that the poultice 7 oozed out from the surface.

The purpose of the present invention is to solve these problems; there are no air bubbles in the poultice applied to the base cloth, the thickness of the poultice is constant, and the quality is maintained so that it can be easily applied to the affected area. We propose an apparatus for manufacturing pads that can form mutually orthogonal paste-free lines that are effective even when cutting into commercially available sizes.

Means for Solving the Problems: In order to achieve the above-mentioned object, the pad manufacturing apparatus of the present invention includes the following steps: A base cloth roll and a cover film are respectively placed on a base cloth roll and a film roll that are arranged side by side in close proximity to each other. On the other hand, above the base cloth roll and film roll, a patch feeder having an opening in the approach line area of both rolls is provided to feed the base cloth and cover film to opposite positions. In a bulge manufacturing device in which a bulge is poured onto the contralateral surface, the bulge feeder has an edge along the rotational surface of the film roll and is arranged in parallel in the length direction of the film roll in the area where the lower part of the pus feeder opens. A plurality of fingers and a pair of film rolls are provided behind the disposed fingers, and ribs are provided at a predetermined pitch on the roll located on the cover film side of the pair. The structure includes a finishing roll.

Effects and Effects of the Invention: In the device of the present invention, the cover film is immediately attached to the base cloth at the same time as the plaster is applied, so air bubbles are entrained in the plaster by the action of the base cloth roll and the film roll. Pap suitable for treatment with constant quality without any problems can be smoothly manufactured. In addition, the bulging agent-free line in the way that the bulges migrate during bulging production is formed by the action of the fingers, and the bulging agent-free line in the direction perpendicular to the direction in which the bulges migrate is pressed by the ribs of the finishing roll to produce the bulges. formed with The pressing force applied to form the non-pump agent line in the direction perpendicular to the direction in which the pads migrate is applied by rolling pressure between the base cloth and the cover film, which are to be the front and back sides of the pads. It has the function of correcting the elongation of the base fabric, etc. that tends to occur when the plaster is applied, and returning it to its original length.
Furthermore, by cutting with these non-pumping agent wires, the bulging agent does not ooze out when the bulging agent is cut like in the case of the bulging agent obtained by conventional techniques. are no longer interconnected.

Therefore, the poultice obtained by the device of the present invention is hygienic because the poultice hardly comes into contact with the air, and the poultice does not ooze out because it is cut with a no poultice line.
Deterioration due to exposure to the poultice is also prevented.

Embodiment: Next, a specific embodiment of the present invention will be described with reference to the drawings.

The device of the present invention performs the application of a poultice to a base cloth, the adhesion of a cover film, and the spreading pressure in a single step in close connection.Specifically, as shown in FIG. A base cloth roll 11 is formed by using a friction roll having a rough surface such as a corundum-coated peripheral surface, and a film roll 12 parallel to this roll is provided at an appropriate interval. And below the approach line of the film roll 12, there is a film roll 1.
A spreading pressure roll 13 is provided at an appropriate interval from 2,
Further, a cataplasm feeder 2 is provided above the approach line.

A film roll 1 is placed in the lower opening of the patch feeder 2 as shown by the chain line in FIG.
Fingers 15 made of a thin plate having edges along the rotation plane of the film roll 12 are installed in parallel in the length direction of the film roll 12. At each part of these fingers 15, the plaster 7 is not applied or becomes very small, and a plurality of plaster-free lines appear in the direction of movement of the pad 10.

Furthermore, a pair of finishing rolls 14 and 14' are provided downstream of the film roll 12. Of the finishing pair, the rotating surface of the roll 14 located on the cover film 6 side is provided with ribs at a predetermined pitch perpendicular to the direction of transition of the pad 10. It is possible to exert a pressing force on the pad 10 by the pinching pressure with the pad 10 and form a pad-free line perpendicular to the direction of movement thereof.

When the device of the present invention is actually used, the base cloth 5 is wound in a non-slip manner around the base cloth roll 11 rotating clockwise as shown in FIG. The cover film 6 is wound around the film roll 12 and fed in the direction of the additional arrow. Then, the paste is delivered from the dressing feeder 2 (the mechanism for pushing out and injecting the dressing 7 housed inside is not shown), which has an opening in the area where the base cloth roll 11 and the film roll 12 approach each other. Pour agent 7 toward both rolls. Here, the base cloth roll 11 can be moved forward and backward as shown in arrow a, the film roll 12 as shown in arrow b, and the rolling pressure roll 13 as shown in arrow c. The distance between the body circumferential surfaces of the film roll 12 and the spreading pressure roll 13 should be set to be slightly larger than the thickness of the pad to be obtained, and the distance between the body circumferential surfaces of the film roll 12 and the spreading pressure roll 13 should be set to be approximately the same as the thickness of the pad to be obtained. is preferred. Further, the base cloth roll 11, the film roll 12, and the rolling pressure roll 13 are each individually driven to rotate by, for example, a DC motor, and each roll individually rotates at a required rotational speed, which can be increased or decreased.

The paste 7 poured onto the opposite surfaces of the base cloth 5 and cover film 6 is formed by the fingers 15 into a paste-free line along the pad transfer direction, and at the same time,
Through the base cloth roll 11 and film roll 12, a clamping pressure is applied while being subjected to a kneading action, and the air bubbles contained inside are completely eliminated and the paste is applied to the base cloth 5 in a dense state, and the bulge agent is applied to the base cloth 5 in a dense state. A cover film 6 is attached to the surface. The pad 10 which has passed between the film roll 12 and the rolling pressure roll 13 reaches the finishing rolls 14, 14', where a pad agent-free line perpendicular to the pad transfer direction is formed and the pad 10 is transferred to the next cutting step.

In this case, the base cloth roll 11, film roll 12, and rolling pressure roll 13 are individually driven so that the feeding or unwinding of the base cloth 5, cover film 6, and pad 10 can be adjusted independently. This contributes to the setting of the bulge formation rate corresponding to the difference in the type and consistency of the bulge agent, and to the elimination and prevention of curling or wrinkling of the bulge cover film.
