Description

Description Method for squeezing viscous material and squeezing device

The present invention relates to a squeezing method and a squeezing device used for squeezing a viscous body from a package in which the viscous body is stored in a flexible packaging container. Background art

Conventionally, as a device for squeezing out a viscous material, for example, an adhesive pink, filled in a flexible packaging container such as a bag (bouch) or a tube from the packaging container, for example, As described in Japanese Patent Publication No. 2000-216, the bag placed on the base is pressed from above with a lip, and the roller is pressed from the bottom of the bag. There is known an apparatus configured to squeeze out the contents (liquid material) from an opening of a bag body by traveling toward the opening.

However, in the above-described squeezing device, when the soft bag is pressed by the roller, the bag may be shirred. Then, since the liquid material adhering to the inner side of the squeezed portion could not be squeezed out by the roller, the amount of residue after squeezed out increased, which was dissatisfied.

Also, the bag needs to have an engaging portion that engages with the fixing pin, so that it is difficult to cope with various types of bags, and if the engaging portion is provided, the seal at the bottom of the bag is weak. Since there is a possibility that the situation may become worse, improvement was desired.

Furthermore, if the roller is moved to a position near the opening of the bag, the roller may be contaminated by the contents protruding from the opening. If the end point of the running of the roller is slightly away from the opening of the bag, the liquid material remains between the opening and the opening. It is troublesome to scrape off the liquid material remaining near the opening with a spatula or the like, and there is a risk that the roller may be soiled during scraping. Roller gets dirty It is inconvenient to continue the work, for example, the rollers become slippery, and it is difficult to clean the rollers frequently.

When the content is a high-viscosity liquid material, as shown in FIG. 5, when the bag 20 is pressed between the base T and the roller R, the opening 20 c of the bag 20 is pressed. In some cases, the liquid 21 rises upward and cannot be properly dropped into the receiving container. The liquid 21 is wasted and the squeezing device is soiled. If the hand 20 presses the vicinity of the opening 20 c of the bag 20 to suppress the rise of the bag 20, there is a risk that the finger or the like may be pinched by the roller R. In addition, the pressure of the throttle is locally concentrated, and the bag 20 may burst, which is a problem.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a squeezing method and a squeezing device capable of safely squeezing a viscous content without waste with little residue. Disclosure of the invention

In order to solve the above-mentioned problems, the present invention relates to a squeezing method used for squeezing a viscous body from a package in which a viscous body is stored in a flexible packaging container, the method being rotatably connected. Squeezing the viscous body by squeezing the package with the plate members in a state where the opened package is arranged between the two plate members. provide.

The pinching of the plate-like member is preferably performed by pressing one or both of the two plate-like members from one end to the other end of the plate-like member with a mouthpiece. . By pressing with a roller in this way, the pressing force can be applied to the plate-like member more efficiently, and workability is improved.

The method of the present invention can be suitably applied to a package in which the packaging container is a bag, and can also be suitably applied to a package in which the packaging container has a plurality of storage chambers for storing the viscous material. In this case, the package body folded so that the plurality of storage chambers are overlapped is disposed between the plate members, and the packaging container is pressed by the plate members. Thus, the viscous body can be squeezed out with a uniform force in response to the uneven thickness of the package.

The present invention relates to a squeezing device used for squeezing a viscous body from a package in which a viscous body is stored in a flexible packaging container, comprising: a support plate for supporting the package; And a pressing plate rotatably attached at one end to the package, wherein the package supported by the supporting plate can be pinched between the supporting plate and the pressing plate. To provide a squeezing device.

In this squeezing device, it is preferable that a roller that presses the pressing plate against the support plate is installed so as to be able to run from one end of the pressing plate to the other end. Thereby, a pressing force can be efficiently applied to the pressing plate.

It is preferable that guide mechanisms are provided on both sides of the support plate to guide the rollers. This allows the roller to run straight in the pressing direction against the pressing plate, and the squeezing effect is further enhanced.

Examples of the guide mechanism include a mechanism having a rack gear combined with a gear provided on the shaft of the roller. As a result, the gear provided on the shaft of the roller engages with the rack gear, so that the roller moves forward reliably and in parallel, thereby improving workability.

It is preferable that a handle for operating the roller is provided at one end of the shaft of the roller. This makes it possible to reduce the force required to rotate the gear that propels the roller by the principle of leverage, thereby reducing the manpower required for squeezing.

FIG. 5 is a schematic cross-sectional view for explaining the inconvenience when a conventional squeezing device is used. BEST MODE FOR CARRYING OUT THE INVENTION

This squeezing device 1 has a rectangular support plate 2 on which a package can be placed and supported, and a hinge 3a at one end 3a with respect to one edge of a long hole 2a formed in the support plate 2. And a pressing plate 3 rotatably connected by 3b. The support plate 2 and the pressing plate 3 have a function as a plate-like member for pressing the package.

The support plate 2 is mounted on legs 5 arranged at four corners, and constitutes a platform on which the package is placed. Further, the package support region 2b on the surface of the support plate 2 facing the pressing plate 3 has a sufficient area for placing the package.

On the support plate 2, a roller 10 that can travel so as to press the pressing plate 3 from one end 3a to the other end 3c on the opposite side is horizontally disposed.

The roller 10 extends in the longitudinal direction of the roller body 11 (in the direction of the center axis, left and right in FIG. 1 (b)), and the roller body 11 is formed of a cylindrical body such as stainless steel or hard plastic. A pair of gears 13 provided at both ends of the shaft 12, a haptic portion 12 a provided between the roller body 11 and the gear 13, and a shaft 1. A handle 14 attached to one end of the gear 13 protruding from one of the gears 13 so as to extend in a direction perpendicular to the shaft 12 ο

The roller body 11 is rotatably mounted on the shaft 12 by a bearing (not shown).

Further, the squeezing device 1 has a guide for guiding the movement of the roller 10. The lock mechanism 4 is provided on both sides of the package support region 2 b on the support plate 2 and the pressing plate 3.

Here, the guide mechanism 4 includes a rack gear 4a which is combined with the gear 13 of the roller 10 described above, a rod-shaped guide member 4b which slides on the hub portion 12a, and a guide member. And a column 4c for fixing the base 4b away from the support plate 2. Each of the rack gear 4 a and the guide member 4 b extends along both edges of the support plate 2.

By rotating the handle 14 to drive and rotate the shaft 12 of the roller 10, the gear 13 attached to the shaft 12 translates while rotating on the rack gear 4a. With the translation of the gear 13, the roller 10 advances on the pressing plate 3 from one end 3a to the other end 3c. The range of movement of the roller 10 is regulated by columns 4c attached to both ends of each guide member 4b, and extends up to the point where the shaft 12 of the roller 10 contacts the column 4c. .

Further, since the hub portion 12a attached to the shaft 12 is pressed down from above by the guide member 4b, the mouthpiece 10 is prevented from being lifted up, and The pressing force can be applied reliably.

As the package to which the squeezing device 1 is applied, in particular, a liquid or paste-like viscous material such as an adhesive, an ink, or a conductive base may be used as a flexible material such as a plastic film or a laminate film. One stored in a packaging container made of a material having the following. Examples of the form of the packaging container include a bag (bouch), a tube, and a box.

Further, as shown in FIGS. 3 (a) and 3 (b), the present invention can be applied to a package 22 in which a bag having a plurality of storage chambers 23 is a packaging container 20. This kind of bag 20 is for, for example, packing two or more kinds of contents in separate storage rooms 23 so that they can be mixed after opening, and such a bag 20 is applied. Examples of the contents include two-part photocurable resin compositions and thermosetting resin compositions, specifically, two-part adhesives, resist inks, and marking inks. In addition, in the food field, there is a raw material composed of a fatty raw material and a hydrophilic raw material that require mixing after opening.

Next, an embodiment of a squeezing method for squeezing a viscous body that is the content of a package using the squeezing device 1 will be described.

As shown in FIG. 2 (a), the pressing plate 3 is lifted up with the roller 10 positioned at one end opposite to the squeezing direction (to the left in FIG. 2), and the package support area 2 b The package 22 is placed on top, and is sandwiched between the support plate 2 and the pressing plate 3. When the packaging container 20 is a bag 20 having a plurality of storage chambers 23 as shown in FIG. 3, the storage chambers 2 are overlapped as shown in FIG. When the seal portion 24 between the three is folded, the width of the package 22 (the dimension in the left-right direction in FIG. 3B) is reduced, and the required area of the package support region 2b can be reduced. Preferred.

One end of the package 20 is opened before or after the package 22 is placed on the support plate 2. Further, the package 22 is placed at a position where the opening 20 c protrudes from one end 2 c of the support plate 2.

Below the support plate 2 on the side where the opening 20 c is located, a receptacle 30 such as a bucket for receiving the viscous body 21 squeezed from the packaging container 20 is arranged.

Here, by operating the handle 14 and rotating it in a predetermined direction as shown in Fig. 2 (a), the gear 13 fixed to the shaft 12 moves while rotating on the rack gear 4a. Then, with the movement of the gear 13, the roller 10 moves from the one end 3 a side to the other end 3 c while pressing the pressing plate 3. Then, the viscous body 21 is squeezed out from the opening 20 c of the package 22 sandwiched between the pressing plate 3 and the support plate 2 toward the receiver 30.

As shown in FIG. 2 (b), when the roller 10 is moved to the other end 3c side of the pressing plate 3, the rigidity of the pressing plate 3 causes the opening of the packaging container 20 to move as shown in FIG. It is possible to squeeze well to the portion of L near 20 c, and the residue can be extremely reduced. Even if the liquid material 21 adheres without soiling the roller 10, it is the part of the pressing plate 3, and it is easy to remove the soil. Since the roller 10 cannot travel beyond the position where it abuts the column 4c of the guide mechanism 4, the roller 10 does not come into contact with the vicinity of the opening 20c of the packaging container 20. Contamination due to contents 21 of 0 is suppressed.

In the present embodiment, the package 22 is arranged between the support plate 2 and the pressing plate 3, and the pressing force of the roller 10 applied to the package 22 via the pressing plate 3 causes the package 2 to be pressed. The contents 2 1 of 2 are squeezed out. For this reason, the squeezing pressure of the roller 10 is partially dispersed by the pressing plate 3 and transmitted to a wider area of the package 22, so that the packing container 20 is less likely to shift. However, the rupture of the packaging container 20 is also prevented. As a result, the contents 21 remain in the packaging container 20 and can be squeezed out without waste. Even if the packaging container 20 ruptures, the presence of the pressing plate 3 can minimize the scattering of the contents 21. Moreover, since it is not necessary to hold the vicinity of the opening 20c of the packaging container 20 with a hand or the like, squeezing can be performed safely.

At the beginning of drawing, as shown in FIG. 2 (a), the pressing force applied from roller 10 to one end 3 a of pressing plate 3 is applied to bottom 20 a of packaging container 20 via pressing plate 3. Not only is it transmitted to the middle part 20b between the bottom part 20a and the opening part 20c.

For this reason, the distance between the portion where the content 21 is deformed by pressing and the opening 20 c is short, so that the content 21 can be squeezed out smoothly and the squeezing operation can proceed promptly. .

Even at the end of squeezing, the pressing force from the roller 10 can be uniformly applied to the packaging container 20 via the pressing plate 3, so that the contents 21 can be reliably squeezed out.

During squeezing, the package 22 is sandwiched between the support plate 2 and the pressing plate 3, so that the surface of the package 20 and the support plate 2 and The friction between the pressing plate 3 and the pressing plate 3 increases, and the pressing force is transmitted to the package 22 more reliably, so that slippage and misalignment hardly occur. As a result, the efficiency of squeezing can be improved, and an engagement hole for fixing the packaging container 20 to the squeezing device 1 is provided. In particular, since it is not necessary to provide and fix, it is possible to perform squeezing in accordance with a wider variety of packages 22.

The roller 10 can be rotated by the handle 14 with a radius of rotation larger than the radius of the roller body 11, so that the roller 10 can be driven with less effort.

Since the shaft 13 of the roller 10 is provided with a gear 13 that is compatible with the rack gear 4a of the guide mechanism 4, the rotation of the shaft 12 by operating the handle 14 is efficiently performed by the roller. 10 can be converted to a translational motion.Even if the contents 21 are a high-viscosity liquid, the rollers 10 can be reliably advanced by overcoming the viscosity of the contents 21 in the package 22. Can be done. Further, the guide member 4 b is provided in parallel with the rack gear 4 a so as to restrict the upward movement of the haptic portion 12 a attached to the shaft 12 of the mouthpiece 10. Since the roller 10 is provided along the moving direction (squeezing direction), it is possible to prevent the roller 10 from rising. As a result, the pressing force can be effectively applied to the package 22 by the roller 10 via the pressing plate 3, and the contents 21 can be effectively squeezed out of the packaging container 20 without waste. Can be.

In a case where the packaging container 20 has a plurality of storage chambers 23 for storing the viscous body 21, the conventional squeezing method and apparatus require the storage chamber 23 and the space between the storage chambers. Due to the difference in thickness from the seal part 24, etc., it was difficult to press the package 22 uniformly, and there was a problem that the packaging container was sealed and the residual amount was large, but the squeezing method of the present invention And the device use two plate-like members (supporting plate and pressing plate) 2 and 3 for pressing, so that uniform pressing is performed in response to uneven thickness of the package 22 O Low squeezing is achieved o

In particular, as shown in FIG. 3 (b), even when the plurality of storage chambers 23 are folded and pressed, and the actual thickness of the package 22 is increasing, the pressing plate is placed on the package 22. Since the roller 3 is disposed, the roller 10 can be easily moved on the package 22. As described above, the present invention has been described based on the preferred embodiments. However, the present invention is not limited to the embodiments, and various modifications can be made without departing from the gist of the present invention. .

For example, in the above embodiment, one of the two plate-like members for pressing the package is a support plate disposed horizontally, but the present invention is not particularly limited to this. The plate-shaped members are placed in the shape of a letter "C" or another arrangement, the package opened between them is arranged, and the package is pressed by pressing both plate-shaped members from the left and right. It is also possible to squeeze by using.

As described above, according to the squeezing method of the present invention, the pressing force can be applied to a wide range of the package by the two plate-like members, and the contents can be squeezed safely and without waste from the packaging container.

Further, according to the squeezing device of the present invention, the package can be placed on the support plate during the squeezing operation, and the work load is small. Further, the pressing force can be applied to a wide area of the package by the support plate and the pressing plate, and the contents can be safely squeezed out of the packaging container without waste.
