A pair of rollers 35, 35 are provided opposite to each other. The upper one of these rollers 35, 35 is attached by a thumbscrew 36, 36 so that it can move up and down. By adjusting the thumbscrews 36, 36, the roller gap can be changed, and a bag body having a different thickness can be obtained. The sealing material contained in the can be squeezed out reliably. Further, these rollers 35, 35 are linked so as to be interlockable by a gear provided in the frame body, and the sealing material S is squeezed out of the bag body 30 by rotating the rotary handle 37.

[0004]

[Problems to be solved by the device]

 However, such a conventional sealing material squeezer has the following problems. As described above, the conventional sealing material squeezing device is intended to squeeze out the sealing material contained in the bag body without leaving any squeezing residue. It cannot be achieved unless it completely matches the thickness of the bag over the entire width direction. In consideration of this, in the conventional squeezer shown here, the upper roller 35 can be moved up and down to adjust the gap between the two rollers 35, 35 with respect to the thickness of the bag body. It is structured. However, adjustment of the roller gap requires independent movement of the adjusting thumbscrews 36, 36 provided at both ends of the upper roller, and it is extremely difficult to match the gap over the entire width direction of the roller. As shown in FIG. 5 and FIG. 6, the sealing material accommodating bag is usually provided with a heat-welded portion over the entire squeezing direction. It is necessary to finish the thickness of the heat-welded portion evenly. It is extremely difficult to consider the manufacturing technology of. Then, during the squeezing work, the gap between the pressing rollers was partially over or under the width of the bag body during the squeezing work, and the squeezing work could not be performed smoothly, or the unsqueezed residue remained. It is inevitable to end up.

If a problem occurs during the squeezing operation as described above, the squeezing operation must be interrupted and the gaps between the rollers 35, 35 must be readjusted by the thumbscrews 36, 36, resulting in extremely poor workability. There was a problem that it would become.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above problems, and an object of the present invention is to provide a sealing material squeezing device having a simple structure, good workability, and less undrawn residue. The present invention, which has solved the above-mentioned problems, is provided with a holding means for holding an end portion of a bag-shaped container provided at an appropriate place in the upper part of a main body, and a frame provided with a guide part extending from the upper part to the lower part at positions facing each other on the side part of the main body.

[Action]

 The sealing material squeezing device of the present invention is provided at both ends of the pressing roller by suspending the bag body by holding the gripping margin of the bag-shaped sealing material by the holding means at the end of the bag-shaped container provided at an appropriate position on the upper part of the main body. While grasping the handles with both hands at the same time, apply the pushing pressure of the pressing roller to the sealing material inside the bag, and move the pressing roller toward the bottom of the opened bag to seal the inside of the bag. The material is squeezed out. Therefore, since the bag body can be reliably held and the two pressing rollers can be brought into close contact with each other, the bag body can be squeezed out without wrinkling.

[0008]

【Example】

 Next, details of the present invention will be described based on embodiments. FIG. 1 shows an exploded perspective view of a sealing material squeezing device of the present invention. As shown in the figure, two leg members 1 and 1 each having a substantially C-shaped cross section are arranged so that their insides face each other, and at the lower end, a concave portion 3 as an engaging means for facilitating engagement with the mixing container 2 is formed. ································· below the engaging members 4 ··· forming bridging connecting members 5 and 5 to form a U-shaped frame 6, and the two leg members 1, 1 are parallel to each other in the vertical direction. Inverted L-shaped guide part 9 for the roller guide is provided which is provided with a strip guide part 7 ... And which is connected laterally from the upper end with a roller lateral recess 8 ... 9, the shafts 11, 11 of a pair of pressing rollers 10, 10 each having a shaft projecting at both ends are fitted into the guide portions 9 ... And the grips 12 ... It can be moved up and down along the guide part by fitting it on the shaft and moving the handle up and down. And are to be laid in a concave portion for laterally bridged.

Since the rollers 10 and 10 squeeze out the sealing material while sandwiching the bag, the gap between the rollers is set to be equal to or less than the thickness of the bag body and the roller is moved with respect to the bag body. At this time, it is preferable to use a material that does not slip with respect to the bag material so that the roller rotates and the sealing material can be squeezed out efficiently. As such a material, for example, a silicone resin, a polyurethane resin, a polyvinyl chloride resin or the like is effective, and the roller surface can be coated and used. In this case, the sealing material can be squeezed out efficiently while pressing the bag with the elastic force of the resin in addition to the sandwiching force of the two pressing rollers. On the upper part of the U-shaped frame body 6, a holding portion 13 serving as a holding means for holding the end portion of the bag-shaped container is provided. Since this holding portion 13 serves as a connecting member for the upper ends of the leg members 1 and 1 and also as a means for holding the bag body, a structure that can be easily attached above the leg members 1 and 1 is desired. By providing bending pieces 14 and 14 which can be fitted to the upper ends of the members 1 and 1 at both ends of the holding portion and externally fitted to the upper ends of the leg members 1 and 1, the connecting function of the upper part of the frame body is achieved. Has. The holding portion 12 is provided with an opening 15 for attaching / detaching the end portion of the bag-shaped container, and a hooking piece 16 of a bag body grip allowance seal portion 33 is provided adjacent to the opening 15 and the hooking portion 16 is provided. A bite piece 17 is provided behind the piece 16 and holds the gripping seal portion 33. In this bite piece 17, one piece 18 having a V-shaped cross section is hinged to the base material of the upper end connecting portion to the leg member by using a spring and a hinge so as to be elastically biased, and the other piece 19 should be grasped. It serves as a stop member for the seal portion 33. The retention of these seals 33 will be explained in more detail with reference to FIG.

That is, as shown in FIG. 2A, the handle 20 raises the bite piece 17 hinged to the holding portion 13 by the hinge 23 to raise the grip allowance seal portion 33 of the bag body 30 to the hooking piece 16. In addition to covering, the other piece 19 and the hooking piece 16 are occluded by the elastic force of the spring 21 in (b) to sandwich the grip allowance seal portion 33. In this state, the bag body 30 is held by the holding portion 13 for gripping. In order to withstand the weight of the bag body 30 during hanging, it is also effective to provide a notch 22 as shown in FIG. 1 at the tip of the hooking piece 16 as a slip stopper. Further, as another example of the holding portion, it is possible to adopt a structure in which the grip allowance sealing portion is wound around the roller, or a structure in which a rod-shaped body having one end fixed thereto is used for clamping.

FIG. 3 shows how the sealing material is squeezed out. While the bag body 30 hung down by the holding portion 13 is pressed by the pressing rollers 10 and 10 interposed by the guide portions 9 and 9, the rollers 10 and 10 are moved in the direction of the arrow to thereby form a sealing material. S is squeezed into the mixing container 2. In order to more reliably squeeze out the sealing material S, it is effective to set the interval between the guide portions 9, 9 so that the pressing rollers 10, 10 can be in close contact with each other. By using this device, the pressing rollers 10 and 10 can be operated with both hands as shown in FIG. 4, so that the squeezing work can be performed more easily. Even with this method, the unused sealing material remaining in the bag body after squeezing was 1% or less by weight, and it was confirmed that there was no problem as a sealing material squeezing device.

Even when such a squeezing device is used, a partial excess or deficiency in the width direction occurs in the gap between the pressing rollers 10 and 10 during the squeezing work due to variations in the bag body thickness, etc., and the squeezing work is smooth. It may not be possible to do so, or squeezing residue may occur. In such a case, the gripping force of the grips 12 and 12 is strengthened with respect to the unrestricted aperture, and conversely, when the squeezing work cannot be performed smoothly, the gripping force of the grips 12 and 12 is weakened and the rollers 10 and 10 move. You should be able to exercise smoothly. Furthermore, after the work is completed, the pressing rollers 10 and 10 can be moved to the remaining portion of the squeezing operation to perform the squeezing operation again. As described above, according to the present invention, the trouble in the squeezing work due to the variation in the bag body thickness can be extremely easily corrected by adjusting the gripping force of both hands holding the grips 12, 12 while observing the squeezed state. it can.

[0013]

[Effect of device]

 The sealing material squeezing device of the present invention holds the bag body by the holding means and hangs down the bag, and the squeezing work is performed while simultaneously grasping the two grips at both ends of the pressing roller with both hands, so that the bag body is held securely. Since the pressing roller can be operated with both hands, the squeezing work with extremely high workability can be performed. As a result, the bag body does not become wrinkled and there is no squeezing left. In addition, even if a problem occurs due to imperfections in the roller gap, it can be corrected quickly simply by adjusting the gripping force of the handle, so that it is possible to eliminate the waste caused by leaving the diaphragm behind.
