A valve assembly jig for assembling or disassembling the valve seat 16 to be formed, in a state where the valve seat is temporarily fastened to the valve body in advance and the valve opening portion faces upward. An adapter 60 having clamp portions 43 and 44 for positioning and fixing the valve body to the jig body, and a shape portion 64 corresponding to the shape of the upper end surface of the valve seat so as to be engaged with the upper end surface of the valve seat. And a pressing part that is movable in the vertical axis direction so as to press the adapter against the upper end surface of the valve seat, and the pressing part is urged vertically upward and moves in the vertical axis direction. A functioning shaft portion 51, a handle portion 53 that operates to move the shaft portion vertically downward, and the adapter holds the state where the adapter presses the upper end surface of the valve seat by operating the handle portion. And a fixing portion 54 that fixes the shaft portion rotatably around the vertical axis.

  The jig according to claim 1, wherein the valve seat is preferably screwed into an inner peripheral surface of the valve main body.

  According to the present invention, it is possible to realize a jig that does not damage parts during tightening or disassembly, reduces variations in assembly dimensions, and contributes to speeding up of work.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment described below is an example as means for realizing the present invention, and the present invention can be applied to a modified or modified embodiment described below without departing from the spirit of the present invention.

[Configuration of valve unit]
FIG. 1 is a side cross-sectional view showing the overall configuration of a valve unit assembled and disassembled by the valve assembly jig of the present embodiment. 2 is a side sectional view (a) of the valve body of FIG. 1 and a side sectional view (b) of the can mouth member.

  The valve unit 10 assembled and disassembled by the valve assembly jig of the present embodiment is mounted on a beer filling device (not shown) called a filler that fills an empty can with beer in a beer manufacturing process, for example.

  As shown in FIG.1 and FIG.2, 11 is a valve | bulb main body which has a hollow cylindrical external shape. A rectangular plate-like support plate 12 for attaching the valve body 11 to the filler is fixed to the outer peripheral surface of the valve body 11. The support plate 12 is formed with a flow path 12 a that is switched between communication and blocking by the nozzle 13.

  A cylindrical can mouth member 14 that is in contact with an inlet of a container such as a can is fixed to the outer peripheral surface of the lower end portion of the valve body 11. A groove 14a is formed over the entire circumference of the annular tip flange surface of the can mouth member 14, and a resin sealing material 15 is press-fitted into the groove 14a so as to come into contact with the inlet of the container to be sealed. . On the side surface of the can mouth member 14, there is formed an arm portion 14b to which a drive shaft (see FIG. 3) for operating the valve main body 11 in the vertical direction is connected.

  On the other hand, a valve seat 16 that forms a valve opening is fixed to the inner peripheral surface of the lower end of the valve body 11. Further, a conical valve member 17 called a liquid cone is provided at the valve opening of the valve seat 16. The valve member 17 is screwed and fixed to a lower end portion of a hollow cylindrical housing 20 that extends through the valve body 11 and extends vertically upward. Reference numeral 19 denotes a detachable cover member that covers the front end surface of the can mouth member 14 for the purpose of protection and hygiene when not in use.

  A hollow valve shaft member 18 is accommodated in the housing 20 and is biased to a neutral position by springs 21 and 22 and a spacer 23 provided on the outer peripheral surface of the upper end portion of the valve shaft member 18. . The housing 20 is slidable by a predetermined distance with respect to the inner peripheral surface of the upper end portion of the valve body 11 and is biased by a spring 24 provided on the outer peripheral surface of the housing 20. Further, the valve shaft member 18 is restricted from moving upward by the upper stopper 25 and the lower stopper 26, and is restricted from moving downward by the lower stopper 26. The valve member 17 opens and closes the valve opening of the valve seat 16 by driving the valve member 17 when the housing 20 reciprocates in the vertical axis direction relative to the inner peripheral surface of the valve body 11.

  A suction cup-shaped lid seal 27 is fixed to the upper end portion of the valve shaft member 18 extending upward from the pressure cap 30 attached to the upper end portion of the housing 20 by a nut 28. Further, a valve mechanism 29 having a sphere 29 a that can float a predetermined distance in the vertical direction is attached to the lower end portion of the valve shaft member 18, and as the liquid level of the liquid injected into the container approaches the can mouth member 14. When the spherical body 29a rises and the liquid level reaches a predetermined position, the communication of the hollow hole 18a of the valve shaft member 18 is blocked by closing the lower end opening of the valve shaft member 18.

  Next, the drive mechanism of the valve unit 10 will be described.

  FIG. 3 is a front view (a), a sectional view (b) taken along line ii of (a), and a top view (c) of (a) showing the drive mechanism of the valve unit of the present embodiment.

  As shown in FIG. 3, the valve unit 10 is supported by the base member 1 via a support plate 12. A drive shaft 31 extending upward is rotatably connected to the arm portion 14b of the can mouth member 14. The drive shaft 31 is slidably supported on the support plate 12 at the bottom and the base 1 via a bearing 32 at the top. Further, the drive shaft 31 is urged downward by a spring 33 provided on the outer periphery of the drive shaft 31, while the drive roller 34 attached to the central portion of the drive shaft 31 moves up and down in conjunction with the vertical movement. Driven in the direction.

  In addition, in the vicinity of the upper end portion of the drive shaft 31 in the base 1, a rotation shaft 37 is provided in which the link member 36 swings and rotates due to the vertical movement of the drive roller 35. By moving the housing 20 (and the valve shaft member 18) of the valve unit 10 in the vertical direction, the valve member 17 is moved up and down to open and close the valve seat 16.

  That is, when the drive shaft 31 moves to the lower position P1, the can mouth member 14 comes into close contact with the inlet 2 of the container, and the liquid is injected into the container by opening the valve seat 16 in this state. At the same time, the inert gas is injected into the container through the hollow hole 18a of the valve shaft member 18 while the air in the container is pushed out. Further, when the drive shaft 31 moves to the upper position P2, the can mouth member 14 is separated from the inlet 2 of the container, the valve seat 16 is closed by the valve member 17, and the liquid injection is stopped. The
