Description

Detailed Description of the Invention [Industrial Application Field] The present invention is a method for compressing various water-absorbing fiber sheets into small pieces, such as paper lotion masks used in cosmetic packs or paper towels for washing hands. , relates to a fixing device.

[Prior art and its problems] Paper sheets used for cosmetic packs and paper towels used for washing hands (hereinafter collectively referred to as sheets) spread out greatly when in use.
Recently, sheets that can be folded into a small size for storage have become widely used. In particular, when expanded, it is large enough to completely cover the face, but when compressed, it is fixed into a small tablet-like lump with a diameter of about 20 to 30 mm and a thickness of about 5 to 8 mm. It is convenient to carry or store because it does not take up much space, so it is widely used as a so-called lotion mask, which is a face covering with blank cutouts for the eyes, nose, and mouth, for example. It is served to.

However, as a method for compressing and fixing sheets with the above structure into small blocks, for example,
-21215 Publication and Utility Model Application Publication No. 58-176997 disclose only conceptual methods, but it is difficult to actually manufacture this product by an industrial method suitable for mass production. The method was not taught. The method disclosed in each of the above-mentioned publications essentially involves folding a flat sheet into a small size, rolling it into a cylindrical shape, storing it in a desired mold, and then pressing the sheet to tightly fit it into the mold. This method is simply a method of compression molding in a mold under a predetermined pressure using a mold, and is extremely inadequate when actually mass-producing compressed blocks of the sheets. Therefore, the present invention has developed an apparatus that can efficiently perform the work even when sheets folded into a certain shape are stored in a mold and compressed, thereby satisfying the demands for mass production. This is what I did.

[Means for Solving the Problems] That is, the present invention is an apparatus suitable for compressing and fixing the sheets in the form of small blocks, which uses a plurality of female molds formed into cylindrical or rectangular tube shapes. As one set, the plurality of sets are arranged in a circular shape on the same turntable, and are assembled so as to maintain a positional relationship overlapping with at least a part of the turntable so that the lifting plunger of the press machine is disposed, Furthermore, a plurality of upper pressers are attached to the lower surface of the plunger, and a lower presser loosely fitted in the female mold is attached to the lower surface of the turntable directly below the elevating plunger so as to be freely raised and lowered. This is intended to enable mass production of compressed blocks of paper sheets.

[Example] First, an example of paper sheets to be manufactured according to the present invention will be specifically described based on FIGS. The figure shows a state where a lotion mask as a cosmetic pack is spread out into a flat plate shape, and as shown in the figure, a rectangular material sheet 1 is placed in a substantially circular shape (reference numeral 2).
(Reference)) and cut outs or notches 3 for the eyes, nose and mouth. The material sheet is usually a highly water-absorbent nonwoven fabric, but is not limited to this, and may be made of pulp fiber, cloth, or other materials that have water absorption and flexibility. You can use anything.

The circular mask sheet 2 having the above-mentioned shape is then folded and bundled into a small bundle in the order shown in FIG. The bundled item is indicated by numeral 4. When the sheets are bundled according to the above folding order, the sheet spreads the fastest when absorbing water or containing water.
If they are folded any other way, they will not spread flat even when immersed in water, and will often simply absorb water and become bulky. This is because, as mentioned above, lotion masks are not just flat sheets, but are round as a whole, with the eyes, nose, and mouth parts punched out. This is because the material has notches or notches, so if it were simply folded and compressed, it would not spread smoothly even when immersed in water.

In the present invention, the sheet bundle 4 folded according to the order shown in FIGS. Compression is performed using a pair of upper and lower male pressers 12 and 13 that are loosely inserted from the upper and lower openings. That is, the lower presser 13 shown in the figure is fitted in advance into the female die 11, and then the upper presser 12 is inserted into the female die to compress and fix the sheet bundle 4 from above and below. To that extent, the method is carried out in accordance with the conventional method described above.

In the present invention, the compression and fixing operations described above are performed by
This is carried out using the newly developed device shown in the figure, and specific examples thereof are shown in FIGS. 2 to 5. Figure 2 shows
This is a side view showing an outline of the apparatus, in which a turntable 23 is disposed on the lower surface of the elevating plunger 22 in the press body 21, and a plurality of the cylindrical female molds 11 described above are arranged on the upper surface of the table. . One example is as shown in the plan view of FIG. 3, where a set of four (or a set of three) cylindrical female molds 11 are arranged in a triangular or square shape. In the example shown in FIG. 3, a total of 10 sets of these are provided on the same turntable 23. A pair of upper and lower male pressers 12 and 13 are provided in correspondence with each of these female mold groups so that at least one of the female mold groups functions at the same time. establish.
That is, the elevating plunger 2 in the press body
An upper presser 12 corresponding to a set of four female molds 11 described above is attached to the lower surface of the mold 2, and a lower presser 13 having a configuration substantially similar to that described above is provided directly below the presser. Then, as described later, the folded sheet bundle 4 inserted into the female mold 11 is compressed from above and below by the pressers 12 and 13 in the female mold 11 into a thin button-shaped lump. Process. At the same time as the above-mentioned compression process, a required stamping pattern can be added to the surface of the small lump as required. If the pressure contact surface 12a or 13a is previously engraved in a required manner, it is possible to form engraved characters on the product, as shown in FIG. 1, for example.

Incidentally, in the press main body 21, as shown in FIGS. 2 and 3, there is a hole in a position adjacent to the above-mentioned elevating plunger 22 for releasing the small lump compressed in the female die 11 from the die 11. A hollow plunger 24 is separately provided. Number 25 in Figure 2
The member indicated by is a detection rod for detecting the lifting stroke of the lifting plunger 22, and
Limit switch attached to press body 21
The LS-1 is operated at predetermined height intervals by a detection rod that moves up and down together with the lifting plunger to regulate the lifting stroke.

As mentioned above, the turntable 23 to which the plurality of female dies described above are attached is arranged on the operating surface of the elevating plunger in the press body 21, and the rotation center of this turntable 23 is arranged as described below. A drive mechanism 27 is incorporated, by which the table is driven intermittently at regular time intervals. That is, as clearly shown in FIG. 3, a deceleration drive mechanism 27 incorporating a prime mover is attached to the rotating shaft 26 of the turntable 23, and the table 23 is intermittently moved in the direction shown by the arrow in the figure. drive the target. code 28
is a rotary cam that rotates in conjunction with the rotation of the turntable 23, and a limit switch LS-2 is installed in this cam to rotate the table 23.
It is configured so that rotation and stopping are repeated at regular time intervals. Then, during the stop time, a compression action is applied to the sheet bundle 4 inserted into the female die, and this compression action is performed by means of upper pressing forces provided on the upper and lower sides of the turntable. This is achieved by raising and lowering the child 12 and the lower presser 13 within the same female mold at the same time or at different times. That is, as is clear from FIGS. 2 to 4, a total of four upper pressers 12 are attached to the lower end surface of the elevating plunger 22 attached above the table.
The female molds 11 are inserted into the four female molds 11 on the table 23 that is stopped directly below, while the lower presser 13 located on the lower surface side of the table and directly below the upper presser 12 is inserted into the female molds from below. It goes into 11. Pushing up the lower presser 13 from below into the female mold or removing it from the female mold is accomplished by a push-up mechanism 29, which will be described below.

The details of the push-up mechanism 29 are as shown in FIG. 5, and include a circular sliding body 30 having the plurality of lower pressers 13 protruding from the top surface thereof, and an actuating cylinder 31 loosely fitted on the outside of this sliding body. It also includes a crank mechanism 32 that rotates the operating cylinder intermittently, and a cylinder 33 as a drive source is assembled to the crank mechanism. Thus, the actuating cylinder 31 and the circular sliding body 30 engage with a spiral groove 30a carved on the outer circumferential surface of the sliding body, and are integrally attached to the inner circumferential surface of the actuating cylinder. Engagement protrusion 31
are attached so as to be able to slide relative to each other via a. When the crank mechanism 32 finishes rotating the push-up mechanism 29 by the action of the cylinder 33, the position is changed to a limit switch.
This is detected by LS-3, and this time the mechanism 29 is actuated in the direction of retracting the cylinder rod in order to rotate in the opposite direction. .

Incidentally, at the position indicated by the symbol Y in FIG. installed as a source. The hollow plunger has a length that passes through the female mold 11, and as a result of being compressed within the female mold, it comes into close contact with the inside of the mold and has the effect of pushing out the small lump downward. Further, a discharge chute 36 for guiding the small lump released from the female mold is attached to the lower surface side of the turntable 23, located directly below the hollow plunger.

By the way, in the present invention, the sheet bundle 4 described above is packed into a set of three or four female molds 11 mounted on a turntable. Since this turntable is intermittently rotated via the drive mechanism 27 as described above, the sheet bundle is packed while the table is stopped. Similarly, while the table is stopped rotating, the press machine 21
The elevating plunger 22 is operated, and the upper presser 12 attached to the lower surface of the plunger is pushed into the female mold as shown by the chain line in FIG.
At this time, the lower presser 13 disposed on the lower surface side of the female die 11 is also pressed at the same time as the upper presser is pressed.
Or, since it has already risen to the position shown by the solid line in FIG. 4 before that, the sheet bundle 4 loaded into the female mold is in a state where it is sandwiched in a sandwich-like manner by the above-mentioned pressers from above and below. It is compressed and processed into small tablet-like pieces as shown in Figure 1. Incidentally, in the lower presser 13 described above, when the cylinder 33 serving as the driving source is operated, its linear motion is transmitted to the crank mechanism 32 to rotate the operating cylinder 31, and accordingly, the projection 31a is moved against the operating cylinder 31. In addition, since the circular sliding body 30 engaged through the groove 30a is moved up and down, the lower presser 13 attached to the upper surface of the sliding body is inserted into the female mold in advance during compression, or It was made possible to achieve the intended purpose by allowing both to enter at the same time.

[Effects of the Invention] The configuration of the device used in the present invention is as described above, and exhibits the following effects.

According to the present invention, a large number of sheet bundles serving as raw materials for compressed small lumps can be set in the press device at once, and the number of sets of female dies to be installed can be freely set depending on the area of the turntable.

The sheet bundle filled in the female mold is fully automatically compressed in the mold by a plunger mechanism set in a press machine and can be processed into desired small lumps, so that work efficiency is high and mass production is possible.

Although the female mold was cylindrical in the illustrated embodiment,
A female mold having any shape can be set on the turntable, such as a rectangular cylinder shape, an ellipse, a rhombus, etc., without being limited in shape.
