Description

  The present invention relates to a high-viscosity fluid discharge device.

Conventionally, various discharge devices for discharging a high-viscosity fluid contained in a container are known depending on the type and application of the high-viscosity fluid. For ease of work, if the trigger is pulled, the piston pressure In general, a high-viscosity fluid is discharged from the tip of the discharge device. The fluid storage part of these conventional discharge devices is equipped with a rigid cylindrical container with high rigidity to withstand the pressure from the piston, and when used, the one stored in the rigid container in advance is used. The high-viscosity fluid that has been purchased and installed in the main body or stored in a flexible soft container is replaced with a special hard container, and the high-viscosity fluid contained therein is discharged by an extrusion means. It was common.

  However, the conventional high-viscosity fluid discharge device requires a dedicated hard container, and the container after discharging all the contents of the container becomes garbage. Although this dust has a very large gap, it is designed to be rugged to withstand the high pressure of the piston, so it costs a lot of money to dispose of the waste.

In order to solve this problem, a method has been devised in which a soft container having flexibility is stored and refilled into a hard container when used.
However, since this method is very convenient for supplying a high-viscosity fluid that mixes two types of high-viscosity fluids just before use and hardens by the chemical reaction, it has begun to become popular. In the case of a one-component high-viscosity fluid, there is a problem that it is accompanied by a very troublesome operation of directly mixing in a hard container, and in the case of two-component liquid, stirring and mixing once and then transferring to a hard container.

  The present invention has been made to solve such a conventional problem, and does not transfer a high-viscosity liquid contained in a soft packaging material to a hard container. However, an object of the present invention is to provide a high-viscosity fluid discharge device that can be mixed and discharged immediately before using the same device.

The present invention employs the following means in order to solve the above problems.
That is, the present invention
In a state where the first soft container having flexibility and the discharge port of the high-viscosity fluid accommodated therein is sandwiched by applying a pressing force, the first soft container is sandwiched from the bottom side to the discharge port side. A pair of rollers capable of moving;
A holding part for holding the bottom side of the first soft container;
A slidable piston for moving the pair of rollers from the bottom side of the first soft container to the discharge port side;
A slide mechanism for sliding the piston relative to the holding part;
Is provided.

According to the present invention, the soft container for storing the high-viscosity fluid can be used as it is as the first soft container, so that a conventional dedicated hard container is not required. Therefore, the number of parts can be reduced, and downsizing and cost reduction are possible.

  Here, a plurality of second soft containers having flexibility and containing a high-viscosity fluid can be inserted into the first soft container. According to this configuration, by inserting a second soft container for storing a plurality of types of high viscosity fluids into the first soft container, a plurality of types of high viscosity fluids can be simultaneously discharged and mixed. it can.

  According to the present invention, since a soft container for storage or the like can be used as it is, a dedicated hard container becomes unnecessary, and the number of parts can be reduced and the cost for disposal of garbage can be reduced.

Next, a high-viscosity fluid discharge device according to the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a high-viscosity fluid discharge device 1 according to the present invention. The high-viscosity fluid discharge device 1 holds a first soft container 11 having a discharge port 11a that has flexibility and discharges a high-viscosity fluid 10 (see FIG. 2) accommodated therein by applying a pressing force. In this state, a pair of rotating rollers 12 and 13 that can move from the bottom 11b side of the first soft container 11 to the discharge port 11a side and a discharge gun 20 are provided.

  The discharge gun 20 is slidable to move the holding portion 14 that holds the bottom 11b side of the first soft container 11 and the pair of rotating rollers 12 and 13 from the bottom 11b side of the first soft container 11 to the discharge port 11a side. A piston 15, a slide mechanism 16 that slides the piston 15 relative to the holding part 14, an operation part 17 that operates the slide mechanism 16, and a grip 18 that is held by an operator. A general configuration can be applied to each component of the discharge gun 20 except for the holding unit 14.

  Next, each of the above components will be described. The high-viscosity fluid 10 can be exemplified by a paste-like liquid such as a sealant, an adhesive, and a caulking agent and having a very high viscosity of about 50,000 to 500,000 cP. The high-viscosity fluid discharge device 1 of the present invention can be applied to a fluid having a viscosity lower than that of the high-viscosity fluid.

  The first soft container 11 is formed in a relatively slender shape with a resin or the like having such flexibility that it can be crushed by the pair of rotating rollers 12 and 13. As the first soft container 11, a soft container for storing the high-viscosity fluid 10 can be used as it is.

  As shown in FIG. 2, the pair of rotating rollers 12 and 13 holds the first soft container 11 with a pressing force applied from both sides thereof. These rotating rollers 12 and 13 can move while sandwiching the first soft container 11 by rotating in opposite directions. The high-viscosity fluid 10 in the first soft container 11 is moved by moving the rotating rollers 12 and 13 from the vicinity of the bottom 11b of the first soft container 11 to the vicinity of the discharge port 11a while holding the first soft container 11. Can be discharged almost to the end.

  Further, the pair of rotating rollers 12 and 13 are arranged in a state of being overlapped in the vertical direction in FIG. 2, and both end portions of the central shafts 12 a and 13 a of the rotating rollers 12 and 13 are respectively rotated by the side plates 31. It is connected freely. As shown in FIG. 3, the upper ends of these side plates 31 are connected by a connecting plate 32. Thereby, the pair of rotating rollers 12 and 13 are integrated.

The connecting plate 32 that integrates the pair of rotating rollers 12 and 13 is detachably attached to the piston 15 by a mounting bracket 15 a provided at one end of the piston 15. The pair of rotating rollers 12 and 13 can be configured to adjust the interval and fix them at a predetermined interval. When the first soft container 11 containing the high-viscosity fluid 10 is sandwiched between the pair of rotating rollers 12 and 13, the work is simplified by widening the interval between the pair of rotating rollers 12 and 13.

  As shown in FIG. 4, the holding portion 14 of FIG. 1 has a pair of clamping portions 35 and 36 that are connected to each other so as to be openable and closable around a hinge 37 at one end. One clamping part 35 is fixed to the gripping part 18. Moreover, the mutually opposing surfaces 35a and 36a in a pair of clamping parts 35 and 36 are formed substantially flat. Thereby, the 1st flexible container 11 can be reliably hold | maintained between the opposing surfaces 35a and 36a in a pair of clamping parts 35 and 36. FIG. A substantially L-shaped locking piece 38 is rotatably provided on one end side of the holding portion 35 fixed to the gripping portion 18. By holding one end of the clamping part 36 with the locking piece 38 in a state where the clamping part 36 is closed, it is possible to prevent the clamping part 36 from being opened carelessly.

  As shown in FIG. 5, the piston 15 in FIG. 1 is slidably held by a slide mechanism unit 16 fixed to the clamping unit 18. The piston 15 has a length necessary for moving the pair of rotating rollers 12 and 13 from the vicinity of the bottom 11b of the first soft container 11 (see FIG. 1) to the vicinity of the discharge port 11a. The length of the piston 15 can be changed according to the size of the first soft container 11. Further, reference numeral 15 b in FIG. 1 is a stopper that prevents the piston 15 from falling off the slide mechanism 16.

  As shown in FIGS. 5 to 10, the slide mechanism unit 16 slides the piston 15 step by step by operating the operation unit 17. 5 to 7 show a state in which the piston 15 is disposed at the reduction limit position (a position where the attachment portion 15a is closest to the slide mechanism portion 16). 8 to 10 show a state in which the piston 15 is disposed at an extension limit position (a position where the attachment portion 15a is farthest from the slide mechanism portion 16). 5 to 10 show each part in a simplified manner for easy understanding. Moreover, the same code | symbol was attached | subjected to the part same as FIGS.

  As shown in FIG. 6, the slide mechanism portion 16 is pivotally provided at the upper end portion of the operation portion 17 via the first rotation shaft 40 and has a through hole 41 a into which the piston 15 is slidably inserted. A member 41, a protruding portion 42 provided in the gripping portion 18 and having an insertion hole 42 a for inserting the piston 15; And have. As a result, the swing member 41 is constantly urged by the compression spring 43 toward the opposite side of the mounting member 15 a in the piston 15. The operation unit 17 is rotatably connected to the gripping unit 18 at a portion below the first rotation shaft 40 by a second rotation shaft 43.

  As shown in FIG. 6, in a state where the piston 15 is disposed at the reduction limit position, the lower end portion of the operation portion 17 is disposed at a position farthest from the grip portion 18. In this state, the portion around the through hole 41a of the swing member 41 is entirely pressed by the compression spring 42, so that the center axis of the through hole 41a is positioned substantially parallel to the piston 15 as shown in FIG. Is arranged. Thereby, a substantially uniform gap d is formed over the entire circumference between the inner peripheral surface of the through hole 41 a and the outer peripheral surface of the piston 15.

  As shown in FIG. 8, when the operation unit 17 is pulled toward the gripping unit 18 from the state of FIG. 6, the operation unit 17 is centered on the rotating shaft 43 of the gripping unit 18 in FIG. The first rotating shaft 40 that rotates in the counterclockwise direction and connects the swing member 41 and the operating portion 17 moves in a direction approaching the mounting bracket 15 a of the piston 15.

  At this time, the upper side of the swinging member 41 is urged by the compression spring 42 to the opposite side of the mounting bracket 15a of the piston 15, so that the upper side of the swinging member 41 hardly moves and moves only on the lower side. Then, the swing member 41 is inclined with respect to the piston 15.

  As a result, as shown in FIG. 10, immediately after the operation of the operation portion 17, among the opening edges on both sides of the through hole 41a of the swing member 41, the upper portion of one (right side in FIG. 9) opening edge, and The lower part of the other opening edge (left side in FIG. 9) abuts on the outer peripheral surface of the piston 15. That is, the piston 15 is sandwiched between the opening edges on both sides of the through hole 41a.

  From this state, when the operation unit 17 is further operated in a direction closer to the gripping unit 18, the clamping force of the piston 15 by the opening edges on both sides of the through hole 41 a of the swing member 41 increases, and the swing member 41 and the piston 15 are increased. Integrally move against the urging force of the compression spring 42. As a result, the piston 15 extends a predetermined distance (one step) with respect to the grip portion 18.

  When the operating force applied to the operating unit 17 is released after operating the operating unit 17 to the end, the swinging member 41 and the operating unit 17 are returned to their original positions (see FIG. 6) by the elastic restoring force of the compression spring 42. . At this time, the piston 15 is left in the position after the movement. Similarly, by repeatedly performing the operation of bringing the operating portion 17 closer to the gripping portion 18 and the release of the operating force, the piston 15 is moved stepwise to the extension limit position. The high-viscosity fluid 10 can be discharged from the discharge port 11a by a predetermined amount, and finally the high-viscosity fluid 10 in the first flexible container 11 can be discharged almost entirely.

  Next, the operation of the high-viscosity fluid discharge device 1 will be described. As shown in FIG. 1, when the high-viscosity fluid 10 (see FIG. 2) contained in the first soft container 11 is discharged by the discharge device 1, the bottom 11 b side of the first soft container 11 is held by the discharge device 1. As shown in FIG. 2, the bottom portion 11 b side (in the vicinity of the holding portion 14) of the first flexible container 11 is held between the pair of rotating rollers 12 and 13.

  Next, as shown in FIG. 8, the operation unit 17 is operated to be pulled toward the gripping unit 18, and the mounting bracket 15 a side of the piston 15 is extended with respect to the slide mechanism unit 16. As a result, as shown in FIG. 2, the pair of rotating rollers 12 and 13 rotate and move away from the holding portion 14 with the first soft container 11 sandwiched therebetween, and the height from the discharge port 11 a of the first soft container 11 increases. A predetermined amount of the clay fluid 10 is discharged. Then, by repeating the operation of the operation unit 17, the high-viscosity fluid 10 in the first soft container 11 is discharged by a predetermined amount each time the operation is performed, and finally, as shown in FIG. The pair of rotating rollers 12 and 13 reach the vicinity of the discharge port 11a of the first flexible container 11. Thereby, substantially all the high-viscosity fluid 10 in the first flexible container 11 is discharged. Note that the high-viscosity fluid 10 in the first soft container 11 can be stored while the remaining amount is discharged into the first soft container 11 by being discharged as much as necessary.

  According to the present invention, for example, the bottom portion 11 b of the first soft container 11 for storing the high-viscosity fluid 10 is held by the holding portion 14, and the bottom portion 11 of the first soft container 11 by the pair of rotating rollers 12 and 13. With the pressing force applied to the side, the piston 15 is simply slid to the discharge port 11a side of the first soft container 11 by operating the operation unit 17, and the high-viscosity fluid 10 in the first soft container 11 is discharged. A predetermined amount can be discharged from the outlet 11a.

Therefore, the high clay fluid discharge device 1 is not limited to its shape and size as long as the first flexible container 11 is flexible enough to be crushed by the rotary rollers 12 and 13. it can. Accordingly, for example, the first soft container 11 used for storing the high clay fluid 10 can be used as it is, so that a dedicated hard container is not required as in the prior art, and the number of parts, size reduction, and cost reduction are reduced. It becomes possible.

In the above-described embodiment, the case where one first flexible container 11 containing the high-viscosity fluid 10 is set in the discharge device 1 has been described. However, as shown in FIG. In the embodiment, two second soft containers 50a and 50b separately containing two kinds of high-viscosity fluids 10a and 10b are inserted into the first soft container 10 and the first soft container 10 is rotated by rollers 12 and 13.
The high clay fluids 10a and 10b in the two second containers 50a and 50b can be discharged and mixed simultaneously. As with the first soft container 11, the second containers 50a and 50b can use soft containers for storing the high-viscosity fluid 10 as they are. In this case, since a plurality of dedicated hard containers that have been conventionally used can be omitted, the number of parts can be further reduced, the size can be reduced, and the cost can be reduced.

  Further, in the above-described embodiment, the configuration in which the piston 15 is slid by the swing member 41 is applied to the slide mechanism unit 16, but the slide mechanism unit 16 is provided with rack-like teeth on the piston 15 and is provided at the upper end of the operation unit 17. The structure etc. which slide the piston 15 by providing the nail | claw latched by the tooth | gear of the piston 15 and moving the nail | claw by operation of the operation part 17 are applicable.
