BEST MODE FOR CARRYING OUT THE INVENTION

[0011] The liquid material discharge device of the present invention includes a nozzle 4, a storage container 5, and a discharge member 1 that are integrally configured via a housing 3 and that require periodic maintenance work. Only the liquid contact part 1 can be detached from the main body part 6 by making the discharge member and the drive part 7 detachable by a connecting member and the main body part 1 and the housing 3 being detachable. Hereinafter, the best mode for carrying out the present invention will be described by taking a screw-type liquid material discharge device as a specific example.

[0012] The housing 3 according to the present invention has a flow path communicating with the nozzle 4 therein, and a screw 2 as a discharge member is inserted therein. Nozzle 3 has an extending portion 302, and the storage container 5 can be attached to the extending portion 302. The extending portion 302 has a flow path formed therein, and communicates the nozzle 4 attached to the housing 3 with the storage container 5. The shape and the like of the extended portion 302 are design matters, and can be appropriate for disposing the storage container 5 at an arbitrary location according to the specifications of the discharge device.

The main body 6 includes a holding part to which the housing 3 is attached. Here, when the housing 3 is attached to the holding portion, it is preferable that the housing 3 is attached while sliding in the horizontal direction. This is because by supporting the housing 3 with a slide member or the like provided in the holding part, it is possible to prevent the liquid contact part 1 from dropping when the liquid contact part 1 is attached or detached. For example, it is preferable that a convex portion or a concave portion is provided on the side of the housing 3 and a concave portion or a convex portion facing the convex portion or the concave portion is provided in the opening of the holding portion, and these are fitted.

[0014] Further, in order to connect the discharge member (screw 2) and the drive unit 7, it is assumed that the liquid contact unit 1 needs to be configured to be movable up and down. As a means for realizing it, the housing 3 may be configured to be movable up and down with the holding unit mounted, or the drive unit 7 may be configured to be movable up and down. In the former case, it is preferable that a space for guiding the vertical movement of the housing 3 is provided in the holding portion.

Further, the holding portion has a fixing means for fixing the mounted housing 3, and for example, the housing 3 is fixed by screw holes 303 and 905 as shown in FIG. 2.

[0015] It is preferable that the connecting member for connecting the screw 2 and the driving unit 7 incorporating the driving means such as a motor can be connected without using the screw means or the like. For example, as shown in FIG. 3, by fitting a shaft end 201 having a hexagonal chamfered shape and a connection hole 801 having a shape matching the cross-sectional shape of the shaft end 201 being chamfered, screw means and the like can be obtained. The drive of the drive unit 7 can be transmitted to the wetted part 1 without using it.

In the example of FIG. 3, it goes without saying that the combination of the shaft end 201 and the connection hole 801 is not limited to a hexagon.

[0016] The wetted part 1 is preferably fixed at two or more locations at least a fixed distance from the main body part 6. For example, in the liquid material discharge device having the configuration shown in FIG. 1, the storage container 5 and the drive unit 7 are fixed by the storage container fixture 11, and the housing 3 is fixed by the holder 9 that is a holding unit. [0017] In the following, the power of explaining the details of the present invention by way of examples The present invention is not limited to any examples.

An extension portion 302 having a flow path formed therein is fixed to the rear end portion 304 of the housing 3, and the storage container 5 is fixed to the extension portion 302.

The holder 9 is a member to which the housing 3 is attached, and an inner surface thereof includes a holder upper inner surface 902 and a holder lower inner surface 903.

The holder upper inner surface 902 is an upper portion of the inner wall surface, the inner portion is shaped along the outer periphery of the protruding portion 301 of the housing 3, and the front portion is formed with a convex portion. With this configuration, the housing 3 inserted into the holder 9 can move in the vertical direction along the inner wall surface at the back, and the rear end 304 is protruded from the front by the rear end. Limited by. The vertical dimension of the holder upper inner surface 902 is configured to be the same as or slightly larger than the vertical dimension (thickness) of the protruding portion 301 of the housing 3 and more than the depth of the connection hole 801 (not present) Or more than the length of the shaft end 201).

The lower inner surface 903 of the holder is a lower portion of the inner wall surface adjacent to the lower upper inner surface 902 of the holder, and the inner portion is formed along the outer periphery of the protruding portion 301 of the housing 3 like the upper inner surface 902 of the holder. The direction is formed to be approximately the same width as the protrusion 301. The vertical dimension of the inner surface 903 of the lower portion of the holder is configured to be the same as or slightly larger than the thickness of the protruding portion 301 of the housing 3.

[0021] At the lowermost end of the holder 9, a stopper 901, which is a substantially U-shaped convex portion adjacent to the holder lower inner surface 903, is provided. The stopper 901 serves as a rail means when the housing 3 is attached to and detached from the holder 9 and also functions as a fall prevention means.

An upper surface 904 having a substantially U-shaped cut is formed at the uppermost end of the holder 9. The upper surface 904 also functions as a vertical positioning means when the housing 3 is mounted.

As shown in FIG. 3, the screw 2 has a spiral wing, and has a shaft end 201 formed by chamfering the side surface over a certain length from the end on the drive unit 7 side. The coupling 8 has a connection hole 801 having a shape matching the cross-sectional shape of the shaft end 201.

Since the shaft end 201 is provided, the rotational force can be transmitted only by fitting the shaft end 201 into the connection hole 801, so that the liquid contact part 1 and the main body part 6 can be easily separated and combined.
