Description

  The present invention relates to a jig for fixing a flexible film-like amorphous liquid container containing a liquid.

  Various standard containers such as cans, bottles, and hard plastic bottles are used to store and transport liquids such as drinking water, fuel kerosene, and industrial chemicals. In recent years, flexible film-like bag-like containers have begun to be used in a wide range of applications in order to easily dispose of such containers and to reduce the weight of the containers themselves (for example, Patent Document 1).

  Such a container can be folded and stored after use, and the weight of the container itself is very light, so that a great effect such as a significant reduction in transportation cost is exhibited. In addition, a liquid supply device that sends out liquid stored in such a flexible film-like bag-like container, for example, drinking water, industrial chemicals, or the like, is also on the market (for example, Patent Document 2).

  However, in the case of a liquid supply apparatus using an irregular liquid container, a device different from that of a regular container is required because the shape of the container itself is irregular. For example, a device fixing method, a container transport method, and the like.

  And since the shape of the container itself is indefinite, the container can be fixed by placing it in some frame and installing it at a predetermined installation location inside the liquid supply device, or by storing it in a box in advance. It is necessary to install the entire box at a predetermined installation location inside the liquid supply apparatus.

  However, since the contents are liquid, the weight is often heavy. For example, when the inside of the liquid supply device is a narrow space, a heavy flexible container is directly installed at a predetermined installation location in the liquid supply device. Difficult to do.

  On the other hand, even when adopting a form in which a container is previously stored in a box and installed in a predetermined installation place with the box, the burden on the operator is reduced with respect to the overall weight including the weight of the box. Means are needed.

  Furthermore, since the size (outside dimension) of the container may vary depending on the capacity, the box is required to be compatible with various sizes of containers and spouts provided in various sizes of containers. .

  The present invention has been made in view of these points, and an object of the present invention is to provide an elaborate holding jig that can easily take in and out an irregular liquid container.

In the present invention, a bag part consisting of a flexible film-like member, the spout having an annular flange portion projecting from the upper end outer periphery of the tubular neck portion which is attached to the mouth and neck portion of the bag portion to the outside, consists and a holding jig amorphous liquid container for accommodating and fixing the amorphous liquid container, a box body whose upper surface consists of a side wall portion has an opening which is erected around the bottom and the bottom, the side wall portion upper is fixed to the box body in Suyo out tension toward the center of the opening from the includes a spout engaging portion spout amorphous liquid container accommodated in the box body engages the spout engaging The joint portion has a guide groove having a width smaller than the outer diameter of the annular flange portion and larger than the diameter of the neck portion, and positioning means capable of moving to a liquid container attachment / detachment position that does not block the opening when the amorphous liquid container is attached to or detached from the box , and having a movably is arranged vertically on the side wall of the box body , Depending on the height of the amorphous liquid container for containing, amorphous liquid Note installation position as deform the fixed part of the side wall of the outlet engaging part is not applied is adjusted, characterized in that A container holding jig is provided.

  Preferably, the holding jig includes a movement assisting mechanism that facilitates conveyance, and the movement assisting mechanism includes a handle portion disposed on the side wall portion of the box body and / or a friction reduction mechanism disposed on the bottom portion of the box body. Suppose that

  If the holding jig for the irregular liquid container according to the present invention is used, when the irregular liquid container is taken in and out of the holding jig, the spout engaging portion is moved to a position that does not obstruct the opening of the holding jig. Therefore, it is possible to easily take in and out the irregular liquid container.

  Even when a pipe equipped with a pump is inserted into the spout and the liquid is discharged to the outside, the spout is pulled by hooking the spout onto the spout engaging portion positioned so as to protrude to the center of the opening of the holding jig. Since it is fixed, liquid can be discharged stably even in an irregular liquid container.

  In addition, since the handle part and / or the movement assist mechanism are provided, the operation of transporting (installing) the irregular liquid container to a predetermined installation place accommodates the irregular liquid container in the box of the holding jig. It is possible to carry a heavy and irregular liquid container easily by the handle and / or the movement assist mechanism.

  Further, by arranging the height of the spout engaging portion so as to be movable in the vertical direction, even if the size of the irregular shaped liquid container is different, the whole of the amorphous liquid container including the liquid weight in the spout engaging portion is arranged. Since it does not hang so that weight may be applied, the trouble that weight is applied to a spout engaging part and a spout engaging part is damaged can be avoided.

  The above explanation is an explanation of an example in which the holding jig 6 for the irregular liquid container 8 of the present invention is applied to the supply of the abrasive stock solution of the mixed liquid supply apparatus 2. Hereinafter, details of the holding jig 6 will be described. A simple structure will be described.

  Referring to FIG. 3, a perspective view of an example of the irregular liquid container 8 is shown. The irregular liquid container 8 includes a bag portion 48 made of a flexible film-like member, a cylindrical neck portion 52 attached to the mouth of the bag portion 48, and an annular flange portion 54 that projects outward from the outer periphery of the upper end of the neck portion 52. And a spout 50 provided. In the bag portion 48, in addition to the above-described abrasive stock solution, liquid 49 such as drinking water, kerosene for fuel, and industrial chemicals can be accommodated.

  Referring to FIG. 4, a perspective view of the holding jig 6 according to the embodiment of the present invention is shown. The holding jig 6 includes a box 7 that forms an accommodation space 63 for accommodating the irregular liquid container 8 (FIG. 3). The box 7 is composed of a plate-like bottom portion 56 and side wall portions 58 erected around the bottom portion 56, and an upper surface is opened (opening 62).

  The side wall portion 58 of the box body 7 is provided with handle portions 59 and 59 used when the box body 7 is conveyed. In the present embodiment, the box body 7 is configured to have a pair of rotating handle portions 59 and 59 having a rotation fulcrum on the front surface side and the rear surface side. It becomes possible to convey the box 7 by suspending it.

  On the other hand, the handle parts 59, 59 are arranged so as to fall sideways when the box body 7 is installed, and can be installed compactly. Further, when the handle portions 59, 59 are tilted sideways, the opening 62 of the box body 7 is opened, and the amorphous liquid container 8 can be easily accommodated and taken out.

  Friction reducing mechanisms 55 and 55 functioning as a movement assist mechanism are provided at the bottom 56 of the box body 7. In this embodiment, it is comprised by sticking the sheet | seat member consisting of a fluororesin on the lower surface of the bottom part 56, for example, when the box 7 is mounted on a floor surface, it slides on the mounting floor surface smoothly. The structure is movable. In addition to this, a synthetic resin having a low friction coefficient such as Teflon (registered trademark) resin or a wheel may be provided.

  As described above, the operation of transporting (installing) the irregular liquid container 8 to a predetermined installation location can be performed while the irregular liquid container 8 is housed in the box 7 of the holding jig 6. Therefore, it is possible to easily carry the irregular liquid container 8 with the movement assist mechanism. Note that either one or both of the handle portions 59 and 59 and the friction reduction mechanisms 55 and 55 may be provided.

  A longitudinal slit portion 64 is formed on the front surface side of the box body 7, and both sides of the slit portion 64 are disposed between the side wall portions 58. As shown in FIG. 5, the slit 64 can visually recognize the side surface of the irregular liquid container 8 accommodated in the accommodating space 63 from the front side of the box body 7, and the irregular liquid container 8 is transparent or semi-transparent. When configured to be transparent, the remaining amount of liquid in the container can be easily confirmed.

  On the rear surface side of the box body 7, the spout 50 (see FIG. 3) of the amorphous liquid container 8 that is extended from the upper end of the side wall portion 58 constituting the rear surface of the box body 7 toward the center of the opening 62 and accommodated in the box body 7. ) Is provided. The spout engaging portion 65 attaches and detaches the indeterminate liquid container 8 to and from the box body 7 and a substantially U-shaped guide groove 65b having a width smaller than the outer diameter of the annular flange portion 54 and larger than the diameter of the neck portion 52 (see FIG. A positioning member (positioning means) 65a that can be moved to a liquid container attaching / detaching position that does not obstruct the opening 62 when being put in and out).

  The positioning member 65a of the present embodiment is configured by a plate-like member, and is provided so as to be rotatable with respect to the side wall portion 58 that constitutes the rear surface of the box 7 so that the plate surface 65c of the positioning member 65a is raised. By rotating, the positioning member 65a can be moved to the liquid container attaching / detaching position.

  As a result, when the amorphous liquid container 8 is put in and out of the holding jig 6, the positioning member (positioning means) 65a can be moved to a position that does not obstruct the opening of the holding jig, so that the irregular liquid container 8 can be easily shaped. The liquid container 8 can be taken in and out.

  On the other hand, the positioning member 65a is movable so that the plate surface 65c of the positioning member 65a is substantially horizontal when the irregular liquid container 8 is accommodated in the box 7 as shown in FIG. ing. The neck portion 52 of the irregular liquid container 8 is inserted into the guide groove 65b of the positioning member 65a, and the annular flange portion 54 is disposed above the plate surface 65c of the positioning member 65a. Is engaged with the spout engaging portion 65 (positioning member 65a).

  Furthermore, as shown to FIG. 6 (A) (B), the positioning member 65a of the spout engagement part 65 is arrange | positioned and accommodated in the side wall part 58 which comprises the rear surface of the box 7 so that it can move to an up-down direction. The installation position is adjusted according to the height of the irregular liquid container 8 to prevent the excessively heavy load from being applied to the fixing portion 70 to the side wall portion 58 of the spout engaging portion 65.

  In the present embodiment, the side wall 58 is provided with an opening 58m downward from the upper end thereof, and the fixing plate 71 is fixed to the side wall 58 so as to straddle the opening 58m in the lateral direction. The fixing plate 71 can be attached to and detached from the fixing portions 58v and 58v provided at a plurality of locations in the vertical direction of the side wall portion 58 by fixing tools 71v and 71v, and the vertical fixing position can be adjusted. ing.

  A positioning member 65 a is fixed to the fixing plate 71 via a connecting plate 72 and a butterfly plate mechanism 73, so that the positioning member 65 a is configured to be rotatable with respect to the fixing plate 71. Then, the vertical position of the butterfly plate mechanism 73 is adjusted according to the adjustment of the fixed position of the fixing plate 71 in the vertical direction, and accordingly, the vertical position of the positioning member 65a can also be adjusted.

  For example, in the case where the size of the irregular liquid container 8 is small (for example, a container having a capacity of 10 liters) and the annular flange portion 54 (see FIG. 5) is disposed at a low position, If the joint part 65 (positioning member 65a) is at a high position, the annular liquid container 8 is held in a suspended state so that the annular flange part 54 is caught by the spout engaging part 65. If it does so, it will be supported by the spout engagement part 65, and the excessive weight will be applied to the fixed part 70 of the spout engagement part 65 by supporting the non-standard liquid container 8 and the whole weight of the liquid in it. End up.

  Therefore, in such a case, the position of the plate surface 65c of the spout outlet engaging portion 65 that has been tilted is lowered by fixing the fixing plate 71 to the lower position as shown in FIG. 6B. Thus, it is possible to prevent an excessive load from being applied to the fixed portion 70 of the spout engaging portion 65.

  Conversely, when the size of the irregular liquid container 8 is large (for example, a container having a capacity of 30 liters) and the annular flange portion 54 (see FIG. 5) is disposed at a high position, the irregular liquid container 8 is not suitable. A load that pushes up the spout engaging portion 65 acts by the bag portion 48 of the fixed liquid container 8.

  In such a case, the fixing plate 71 is fixed to the upper position as shown in FIG. 6 (A), so that the position of the plate surface 65c of the collapsed spout engaging portion 65 is increased. It is possible to prevent an excessive load from being applied to the fixed portion 70 of the outlet engaging portion 65.

  Note that the positioning member 65a of the spout engaging portion 65 is provided with triangular stoppers 65d and 65d (FIG. 4) in a side view, and when the positioning member 65a is tilted and the plate surface 65c becomes substantially horizontal. The stoppers 65d and 65d come into contact with the fixed plate 71. Thereby, when the positioning member 65a is tilted, the plate surface 65c is maintained so as to be in a substantially horizontal state, and does not fall over beyond the substantially horizontal state.

  Then, as shown in FIG. 1, the liquid supply means 66 is attached to the spout 50 of the irregular liquid container 8 accommodated in the holding jig 6, thereby sending the liquid 49 inside the irregular liquid container 8. It becomes possible.

  The liquid supply means 66 includes a delivery pipe 68 that is inserted into the bag 48 from the spout 50 of the irregular liquid container 8, a suction pump 20 that is interposed in the middle of the delivery pipe 68, and a delivery pipe 68. And a cock (plug) 70 provided in the vicinity of the outlet portion.

  When the holding jig 6 configured as described above is used, the spout engaging portion 65 prevents the opening of the holding jig when the amorphous liquid container 8 is taken in and out of the holding jig 6. Since the liquid container 8 can be moved to a position where it does not exist, the amorphous liquid container 8 can be easily put in and out.

  When the delivery pipe 68 provided with the suction pump 20 is inserted into the spout 50 and the liquid is discharged to the outside, the spout is inserted into the spout engaging portion 65 positioned so as to project to the center of the opening of the holding jig 6. Since the spout 50 is fixed by hooking 50, the liquid can be stably discharged even in the irregular liquid container 8.

  Further, since the handle portion 59 and / or the movement assist mechanism (friction reduction mechanism 55) are provided, the operation of transporting (installing) the irregular liquid container 8 to a predetermined installation location is performed by the box of the holding jig 6. The irregular liquid container 8 can be accommodated in the body 7, and the heavy irregular liquid container 8 can be easily transported by the handle 59 and / or the movement assist mechanism (friction reduction mechanism 55).

  Further, by arranging the height of the spout engaging portion 65 so as to be movable in the vertical direction, even if the size of the amorphous liquid container 8 is different, the spout engaging portion 65 includes a liquid having a liquid weight. Since the container 8 does not hang so that the entire weight is applied, it is possible to avoid the problem that the spout engaging portion 65 is heavy and the spout engaging portion 65 is damaged.
