In the material pressure feeding device described in Patent Documents 1 and 2, since the pressing member is lowered in the bag via the driving device to apply the pressing force to the material, the pressing member is applied to the inner surface of the bag. It will descend along.
Therefore, there is a problem that the bag is broken when the pressing member is lowered in the bag. Further, when the material has a low viscosity, there is a disadvantage that the material protrudes from between the outer peripheral surface of the pressing member and the inner surface of the bag.
In addition, when a material with a low thixo ratio is to be pumped, when the pressing member is pulled out of the bag to replace the entire bag, the material adhering to the inner surface of the passage of the pressing member drips down and the material is replaced. During the subsequent air bleeding operation, more material than usual must be discarded, and there is also a disadvantage that the workability of material replacement is significantly reduced.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and the purpose of the present invention is that the bag is not torn by the pressing member, and the material protrudes from between the pressing member and the bag. And to provide a pumping device capable of maintaining stable suction and pumping operations.
Another object of the present invention is to provide a pressure feeding device capable of improving workability during material replacement while avoiding wasteful consumption of material.

In order to achieve the above object, the present invention adopts the structure described in the claims. That is, the present invention relates to a container having an open upper end that accommodates a bag containing a viscous material, a pressing member having a passage communicating with the inside of the bag, and pressing the material in the bag via the pressing member. A material pumping device provided so that the material can be pumped,
The pressing member is configured to sandwich the opening side of the bag with the passage communicating with the inside of the bag.

  In the present invention, the pressing member includes a first annular member and a second annular member located above the first annular member, and the opening side of the bag is sandwiched between the first and second annular members. Can be adopted.

  The pressing member includes a first annular member and a second annular member positioned on the upper portion of the first annular member, and the second annular member is fitted in a hole provided in the first annular member. It is preferable to employ a configuration in which a cylindrical portion is provided, and the opening side of the bag is sandwiched between the outer peripheral surface of the cylindrical portion and the inner peripheral surface of the hole.

  Further, a configuration is adopted in which a plate-like member having a plurality of holes is disposed on the second annular member.

  As the viscous material in the present invention, one having a thixo ratio of 3 or less is a suitable target.

Further, the material pressure feeding method according to the present invention includes a step of accommodating a bag containing a viscous material in an open top container,
Clamping the opening side of the bag to a pressing member provided with a passage communicating with the interior of the bag;
Lowering the pressing member in the container and pressing the material together with the container;
And a step of sucking material into the passage of the pressing member.

According to the present invention, since the pressing member sandwiches the opening side of the bag, the bag is pressed together with the material.
Therefore, when the bag is torn or the material has a low viscosity, the inconvenience that the material protrudes from between the pressing member and the bag can be solved.
Further, the pressing member is constituted by the first annular member and the second annular member, and the opening side of the bag is sandwiched between the first and second annular members, so that the opening side of the bag can be reliably secured. Can be pinched.
In particular, a cylindrical portion that fits into a hole provided in the first annular member is provided in the second annular member, and the outer peripheral portion of the bag is sandwiched between the outer peripheral surface of the cylindrical portion and the inner peripheral surface of the hole. Then, the opening side of the bag is inserted into the hole, and then the first annular member is positioned inside the opening of the bag and the tube portion and the hole are fitted to sandwich the opening side of the bag. It becomes possible and work can be performed easily.
Moreover, in the structure which has arrange | positioned the said plate-shaped member, even if the material which remains on the press member side flows in the direction which falls when the press member is extracted from a bag, it acts so that the hole of a plate-shaped member may prevent a flow. In addition, dripping of the material can be prevented.
In addition, although the material in this invention is not specifically limited, The moisture hardening type silicone or moisture hardening type modified silicone of thixo ratio 3 or less is made into the preferable object. The thixo ratio is a value obtained by dividing the “viscosity value at a low shear rate” by the “viscosity value at a high shear rate”. The low shear rate is, for example, 0.1 (1 / s), and the high shear rate is 1.0 (1 / s). An example of an apparatus for measuring viscosity is VAR-50 manufactured by REOLOGICA. Details of the test conform to JIS-K7117.

A pressing member 13 that can sandwich the opening 11A side as an upper portion, a pump 15 that is arranged on the upper portion of the pressing member 13 and sucks and presses the material M in the bag 11 when the pressing member 13 descends, and the pressing member 13 And a wiper plate (not shown) located on the outer peripheral side of the.

  The bag 11 is made of a resin film. When not in use, the bag 11 is sealed by wrapping a band-like member or a string-like member around the upper end side with the material M accommodated therein. When the material is used, the bag 11 is accommodated in the container 12, and the opening 11A is formed by releasing the sealing on the upper end side. In addition, although the material accommodated in the bag 11, ie, the pumping target, is not particularly limited, in this embodiment, a moisture-curing modified silicone having a thixo ratio of 1 is applied. Therefore, the material M has fluidity approximate to that of water candy.

  In the present embodiment, the container 12 includes a substantially cylindrical peripheral wall portion 20 that is oriented in the vertical direction, and a bottom wall portion 21 that is positioned below the peripheral wall portion 20. Although the container 12 in this embodiment employs a pail can, the present invention is not limited thereto, and a resin container may be used.

  The pressing member 13 includes a first annular member 25 and a second annular member 26 that can be fitted and integrated with the first annular member 25 in a state of being positioned on the upper portion of the first annular member 25. . The first and second annular members 25 and 26 have a circular planar shape, thereby leaving a circular gap between the outer peripheral surface of the pressing member 13 and the inner peripheral surface of the container 12, and the wiper plate in the gap. Can be placed.

  The first annular member 25 is constituted by a substantially donut-shaped plate member having a hole 27 that forms a passage in the center. A concave circumferential groove 29 is formed at the center in the vertical direction on the inner circumferential surface of the hole 24 so that the seal ring 30 is received in the circumferential groove 29 as shown in the enlarged view of FIG.
