Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a molding device for a breast-feeding breast-feeding pad.

[Conventional technology]

The production equipment for breast-feeding breast-feeding pads was developed in 1976.
As in Publication No. 43426, while transporting a raw covering material made of paper laminated with polyethylene by an intermittent running belt conveyor, when the raw covering material is stopped, a nipple insertion hole is punched out by a first press mechanism;
Next, when the part of the raw dressing material having the nipple insertion hole reaches the second press mechanism in front of the first press mechanism, the part of the raw dressing material that has the nipple insertion hole is pressed directly above the raw material of the dressing material by the male mold passing through the female mold of the second press mechanism. At the same time, the water-absorbent material material supplied across the coating material material material is punched out, and the coating material material material material material material material material material material material material material material material material material is punched by the supporting rod which rises above the female mold and is exposed to the atmosphere. It is bent into a bowl shape while pushing up, and the punched water-absorbing material is sealed integrally with the original coating material.

When the paper reaches the front sealing mechanism of the second press mechanism, the second polyethylene paper supplied so as to overlap on the upper side is sealed (heated and bonded) to the coating material original fabric by the sealing mechanism, thereby covering the water-absorbing material.

Then, it is punched out using the front press mechanism to obtain a pat.

[Problem that the invention attempts to solve]

Since the punched water-absorbent material is shaped like a bowl by pushing up the water-absorbing material raw fabric using a support rod that penetrates the nipple insertion hole, the problem is that as the center is pushed up, it becomes a conical shape, which prevents it from being molded into a bowl shape that fits the breast. It was hot.

In addition, since the first press mechanism seals the water-absorbing material onto the original coating material, and the second press mechanism seals the second polyethylene paper onto the original coating material, two press mechanisms are required. When the second polyethylene paper is sealed by the second press mechanism, since the bowl-shaped water-absorbing material does not retain its shape, the conical shape is distorted due to the tension generated from the center of the second polyethylene paper toward the periphery during pressing. I had a problem where it tends to become plate-shaped.

[Problem that the invention attempts to solve]

In order to solve the above problems, this invention has a male mold and a female mold with built-in heaters placed above and below to create a bowl-shaped mold that fits the breast, and a device that can be raised and lowered on the outside of the male mold to prevent it from falling off. A freely provided annular box is connected to a suction hole provided at a predetermined position on the bottom wall of this box so as to communicate with the inside of the box, and is designed to provide suction from the time when the male die starts rising until the molded part is taken out. It consists of a hose provided and a passage provided so that the inside of the box communicates with the atmosphere.

[Effect]

When the patch disk is supplied (placed) on the female mold, the male mold is lowered and the female mold and the male mold squeeze the disc and form it into a bowl shape.

At this time, the bottom wall of the box comes into contact with the upper surface of the peripheral edge of the disk protruding from the peripheral edge of the male mold, and is pushed up.

Thus, after a certain period of time, the male form rises.

As the male die rises, the inside of the box is suctioned, so that the peripheral edge of the molding pad is attracted to the bottom surface of the box.

As a result, the part is attracted to the box that rises with the male mold and escapes from the female mold.

In addition, since the box rises behind the rising male mold, the part is released from the male mold, and since the atmosphere and the inside of the box communicate with each other through the passage, the vacuum inside the box is released. , the deformation of the bowl-shaped parts is eliminated.

In addition, remove the pad after stopping the suction inside the box.

〔Example〕

In the figure, A is a patch disk.

As shown in FIG. 4, the disk A overlaps the water-absorbing material 1, which is made by stacking a required number of water-absorbing papers and punching them out into a circular shape, and the top and bottom surfaces of this water-absorbing material 1, and is also sealed on the outer edge of the water-absorbing material 1 ( It consists of a waterproof paper 2 and a covering material 3 such as a non-woven fabric, which are bonded together by heating and punched out on the outside of the seal.

B is a molding device that molds the disc A into a bowl-shaped part C that fits onto the breast.

The above-mentioned molding apparatus B includes a built-in male die 5 and a female die 6 of heaters 4 arranged above and below, an annular box 7 provided on the outside of the male die 5 to prevent it from falling off and can be raised and lowered, and this box 7. The suction hole 8 provided at a predetermined position on the bottom wall of the mold is connected to communicate with the inside of the box 7, and the molding part C
a hose 9 provided for suction until the removal of the
It consists of a passage 10 provided so that the inside of the box 7 and the atmosphere communicate with each other.

In the illustrated case, a cylindrical body 11 having a box 7 on the lower edge is fitted on the outside of the male die 5, and a flange 12 is connected to and protrudes inward from the upper edge of the cylindrical body 11. It is brought into contact with the upper surface of the male die 5 to prevent the cylindrical body 11 from falling off.

Further, although the passage 10 is formed by providing a groove on the lower surface of the bottom wall of the box 7 in the illustrated case, it may be formed by other methods.

As shown in the figure, by providing a protruding pin 14 in the center of the female mold 6 which is given a rising ability by a spring 13, the male mold 5 and the pin 14 can sandwich the disk A, and then the female mold 6 can be inserted into the female mold 6. Since the disc A is pushed in, misalignment of the disc A can be prevented.

Next, the molding method will be explained.

First, after placing the disk A on the female mold 6, when the male mold 5 is lowered by the extension action of the cylinder, etc.
The disc A is formed into a bowl shape by the clamping pressure between the male die 5 and the female die 6.

At this time, since the bottom wall of the box 7 is in contact with the upper surface of the peripheral edge of the disk A protruding from the peripheral edge of the male mold 5, the box 7 is pushed up.

After the molding is completed, the inside of the box 7 is first sucked, and then the male mold 5 is raised, so that the box 7 is raised midway through the rise of the male mold 5.

Therefore, the part C whose peripheral part is adsorbed to the box 7 is completely separated from the female mold 6 and the male mold 5, and
After that, release the suction in box 7 and press Patch C.
Take out.

〔effect〕

As described above, according to the device for molding a patch according to this invention, when a female mold and a male mold are used to mold a disc into a bowl shape that fits onto the breast, and then the male mold is raised, the male mold is raised. Since the box that has attracted the part is raised from the middle, the part is supported by the box and can be taken out without adhering to the female mold or the male mold.

Further, since the atmosphere is communicated with the inside of the box through the passage, there is no need to create a vacuum inside the box.

Therefore, it is possible to eliminate the problem of deformation of the molded part when the male mold is raised in advance.
