The handle portion 93 is configured by, for example, attaching a metal pipe shape to the upper portion of the mounting portion 91, and serves as a handle portion when a person or the like moves the material supply device 100.

(Viscous material supply method)
Next, a method of supplying the viscous material according to the present embodiment will be described. FIG. 21 is a flowchart illustrating a method of supplying a viscous material according to an embodiment of the present invention, and FIGS. 22 to 24 are diagrams illustrating a state of delivering the viscous material contained in the bag body. FIG. 25 is a diagram illustrating how the nozzle is removed from the spout, and FIG. 26 is a diagram illustrating how the nozzle is inserted into a new (other) container.

To outline the material supply method with reference to FIG. 21, the bag 11 is filled with the viscous material M (ST1), then the cap 30 is attached to the outlet 21 of the spout 20 (ST2), and the closing member 40 is capped. Assemble to 30 (ST3). Next, after a lapse of a predetermined time, the cap 30 and the closing member 40 are removed from the spout 20 (ST4), and the nozzle 50 is attached to the spout 20 (ST5). Next, the pump 70 is operated (ST6), and the viscous material M is supplied by the handling operation (ST7). The details will be described below.

In the present embodiment, it is assumed that the accommodating space 12 of the bag 11 is not pre-filled with the viscous material M. First, the bag 11 and the spout 20 are connected to the tank or the like containing the viscous material M by a pipe or the like (not shown). Then, the viscous material M is moved from the tank or the like to the accommodation space 12 of the bag body 11 (ST1). As a result, the viscous material M is filled up to the vicinity of the outlet 21 of the spout 20.

After the viscous material M is filled as described above, the cap 30 is attached to the outlet 21 of the spout 20 (ST2). As shown in FIG. 7, the isolation wall 33 of the cap 30 is arranged closer to the bag 11 in the passage 23 than the outlet 21 in the assembled state. In other words, the isolation wall 33 is arranged inside the outlet 21 in the axial direction x in which the viscous material M flows in the passage 23 in the mounted state with the spout 20. By arranging the isolation wall 33 in this way, by attaching the cap 30, air or the like existing in the spout 20, particularly the passage 23, is pushed out by the isolation wall 33 and the communication hole 32. In some cases, a small amount of the viscous material M is discharged from the communication hole 32.

After confirming that the air or the like in the passage 23 has been released, the closing member 40 is assembled to the cap 30 (ST3). As a result, the accommodation space 12 of the bag body 11 and the passage 23 of the spout 20 are isolated from the outside. The operations from ST1 to ST3 can be performed by the adhesive manufacturer. After that, the bag assembly 10 can be housed in a pail or the like and transported to a customer's production site or the like. The bag assembly 10 can be suitably used, for example, when filling 10 kg or more of a viscous material.

The viscous material M filled in the bag 11 is used after a lapse of a predetermined time. At the time of use, the cap 30 and the closing member 40 are removed from the spout 20 in order to attach the nozzle 50 to the spout 20 (ST4). At this time, the cap 30 and the closing member 40 may be removed at once, or the cap 30 may be removed from the spout 20 after the closing member 40 is removed from the cap 30.

Next, as shown in FIG. 14, the nozzle 50 is inserted into the passage 23 of the spout 20 and attached, and the end portion on the opposite side of the spout 20 is sandwiched and set by the sandwiching portion 66 of the handling portion 60 (ST5). .. Then, the pump 70 is operated (ST6).

Next, as shown in FIG. 22, the mounting member 63 is moved toward the spout 20 on the linear guide 65 while maintaining the state in which the bag body 11 is pressed and sandwiched by the handling members 61 and 62, and the handling operation is performed. I do. As a result, as shown in FIG. 23, the viscous material M existing in the accommodation space 12 of the bag body 11 other than the periphery of the spout 20 moves so as to gather toward the spout 20.

Then, the viscous material M existing in the accommodation space 12 is sent out from the nozzle 50 inserted in the spout 20. As shown in FIG. 24, the handling operation ends when the handling members 61 and 62 come into contact with the contact portion 24 of the spout 20 and the tip portion 51a of the spout insertion portion 51 of the nozzle 50 via the sheet of the bag body 11. (ST7). The viscous material M delivered from the nozzle 50 is pumped by the pump 70.

Next, the pump 70 is stopped (ST8). After stopping the pump 70, the nozzle 50 is withdrawn from the spout 20 as shown in FIG. 25 (ST9). As a result, the viscous material M that should have remained in the passage 23 of the spout 20 is removed in a state of being taken into the inside of the nozzle 50.

When the capacity of the viscous material M to be sent out is insufficient for the required amount and corresponds to a plurality of bag bodies 11 (ST10: NO), the bag body 11 is replaced with a new one (ST11). Then, until the supply of the viscous material M from the bag body 11 reaches the required amount (ST10: YES), the inside of the spout 20a attached to the new bag body 11a filled with the viscous material M as shown in FIG. The operation from the insertion (ST5) of the nozzle 50 containing the viscous material M to the extraction (ST9) of the nozzle 50 is repeated.

When the supply of the predetermined amount of the viscous material M is completed (ST10: YES), the cap 30 is attached to the outlet 21 of the spout 20 (ST12), and the communication hole 32 of the cap 30 is used with bare hands or the handling members 61, 62 and the like. The gas remaining in the accommodation space 12 of the bag body 11 is discharged from the bag body 11. Then, the closing member 40 is assembled to the assembled portion 34 of the cap 30 to isolate the accommodation space 12 and the passage 23 from the outside (ST13).

As described above, in the present embodiment, the bag assembly 10 is attached to the bag body 11 provided with the accommodating space 12 for accommodating the viscous material M, and the viscous material M in the accommodating space 12 is attached to the outside. The spout 20 provided with the delivery passage 23, the communication hole 32 for communicating the accommodating space 12 of the bag body 11 and the passage 23 of the spout 20 with the outside, and the accommodating space 12 of the bag body 11 and the passage 23 of the spout 20 are communicated through the communication hole. A cap 30 which is provided with an isolation wall 33 which is isolated from the outside except for 32, is attached to the outlet 21 of the viscous material M in the passage 23 of the spout 20, and is detachably attached to the cap 30, and is attached to the cap 30. It has a closing member 40 that closes the communication hole 32 in the above. In the cap 30 attached to the spout 20, the isolation wall 33 is arranged on the side of the bag 11 in the passage 23 from the outlet 21.

With this configuration, by attaching the cap 30 to the spout 20, the isolation wall 33 sends out the air remaining in the passage 23 from the communication hole 32 when the bag 11 is filled with the viscous material M. be able to. Therefore, it is possible to suppress the remaining of air or the like in the passage 23 or the like, and thereby suppress the change in the physical properties of the material filled in the bag 11 with time.

Further, at least the accommodating space 12 of the bag 11 accommodates a viscous material M such as a moisture-curable resin. Moisture-curable viscous materials may gel if air remains in the containment space. Therefore, by separating the moisture-curable viscous material M housed in the storage space 12 of the bag 11 from the outside by the cap 30 and the closing member 40, it is possible to suppress the change in the physical properties of the viscous material M over time.

Further, the isolation wall 33 of the cap 30 is formed so that the wall surface at least on the side of the passage 23 is inclined so as to be recessed toward the communication hole 32. Therefore, when the cap 30 is attached to the spout 20, the air or the like remaining in the passage 23 can be effectively guided to the communication hole 32 and discharged to the outside. Therefore, it is possible to prevent air or the like from remaining in the accommodation space 12 and the passage 23, and to suppress changes in the physical properties of the viscous material M over time.

Further, the closing member 40 includes an assembling portion 41 that is assembled to the assembled portion 34 of the cap 30, and a closing wall 42 that closes the communication hole 32 in the assembled state with the cap 30. Further, the assembling portion 41 is configured to include a side wall formed by partially extending the outer peripheral edge portion of the closing wall 42 in the axial direction x intersecting the closing wall 42. Therefore, the closing member 40 can be assembled to the cap 30 with a simple configuration without separately preparing a part for assembling the closing member 40 to the cap 30.

Further, the spout 20 is configured to come into contact with the handling members 61 and 62 via the bag body 11 and to include a contact portion 24 formed in a surface shape similar to the surface shape of the handling members 61 and 62. Therefore, it is possible to prevent a gap from being formed between the handling members 61 and 62 and the spout 20 when the handling members 61 and 62 come into contact with the spout 20. As a result, the viscous material M collected in the spout 20 by the handling members 61 and 62 can be prevented from unintentionally remaining in the accommodation space 12 of the bag body 11 and the viscous material M can be efficiently taken out from the bag body 11. can.
