BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a rotary rod feeding device according to an embodiment of the present invention. 1 and 2 are longitudinal sectional views of a rotary rod feeding device according to an embodiment of the present invention. FIG. 1 shows a direct filling type disposable type, and FIG. 2 shows a cartridge type refilling type.

In FIG. 1, an inner shaft 2 is rotatably provided inside a front portion of an outer shaft 1 having a bottom. That is, as shown in FIG. 3, an annular groove 11 (FIG. 3) is formed inside the front portion of the outer shaft 1, and an opening edge of a cap 5, which will be described later, comes into contact with the upper outer periphery of the outer shaft 1. A step 1a is formed. In the figure, reference numeral 1b denotes a step portion on which a later-described middle screw member 4 is positioned. An annular ridge 21 (FIG. 4) of the center shaft 2 is rotatably engaged with the annular groove 11. At a position appropriately spaced from the annular ridge 21 of the center shaft 2, a convex stopper portion 22 is formed which comes into contact with the upper end of the outer shaft 1 when the center shaft 2 is set on the outer shaft 1.

Further, a large number of ridges 24 are formed in the longitudinal direction adjacent to the annular stopper portion 22. When the center shaft 2 is set on the outer shaft 1, the convex stopper portion 22 just comes into contact with the tip of the outer shaft 1, and this portion projects from the opening of the outer shaft 1. This portion functions as a non-slip so that it can be easily pinched with a fingertip.

Further, an insertion hole 23 as shown in FIGS. 5 and 6 is formed in the bottom of the center shaft 2. The slider 3 as shown in FIGS. 7 to 11 is provided in the insertion hole 23 so as to be movable in the longitudinal direction with respect to the center shaft 2 but not to rotate. That is, the slider 3 includes a rod-shaped shaft portion 32 having a receiving portion 31 on an upper portion and connected to a bottom portion of the receiving portion 31.

More specifically, a rod-shaped material retaining hole 31a is formed in the side wall of the receiving portion 31 for allowing a rod-shaped material to penetrate into a position adjacent to the bottom of the receiving portion 31 during direct filling to lock the rod-shaped material. Are formed facing each other, and similarly, a notch 33 (FIG. 9) is formed at the upper end edge of the receiving portion 31 for locking the rod-shaped object. Are formed. In addition, this cut 33
In the case of the cartridge type as shown in FIG. 2, when the holder 6 holding the rod-shaped object is loaded, the receiving portion 31 is expanded and the setting is easy.

Further, the opening portion of the receiving portion 31 is thin portion 3
1b, and an annular ridge 31c is formed in the middle of the thin portion 31b. In addition, this thin portion 31b
Each of the upper and lower ends of the thick portion following the upper portion has an annular raised portion 31d. Due to these annular raised portions 31d, the outer peripheral wall of the receiving portion 31 is prevented from sliding due to full contact with the inner peripheral wall of the center shaft 2, and the contact / sliding is possible only by a very small portion, that is, only the annular raised portion 31d. Therefore, particularly in the case of the direct filling type, there is an advantage that the slider can easily slide even if the viscous filling solidifies and adheres to unnecessary portions.

On the other hand, the shaft portion 32 has a male thread portion 32a formed intermittently downward from the receiving portion 31. That is, the shaft portion 32 is partially formed with a male screw portion 32a, and a screw is cut in the longitudinal direction between these portions to form a flat portion 32b (FIG. 7). A large-diameter locking portion 32c is formed at the lower end of the shaft portion 32. The shoulder portion 32d of the locking portion 32c secures the central shaft 2d during assembly.
Is chamfered so as to be easily inserted into the insertion hole 23.

Returning to FIG. 1, the shaft portion 32 of the slider 3 is formed to be movable in the longitudinal direction by a middle screw member 4 fixed inside the outer shaft 1. That is, as shown in FIGS. 12 to 15, this middle screw member 4 is formed by assembling a pair of half parts 41,
1a is formed.

More specifically, the middle screw member 4 is composed of half parts 41, 41 connected by a hinge 42, and these half parts 41, 41 correspond to the locking projections 41, respectively.
b, a locking recess 41c is formed. And these half parts 41, 41 are the shaft part 32 of the slider 3 described above.
A female thread portion 41d (FIG. 13) is formed on the inner peripheral wall of the female thread portion 32a for screwing with the external thread portion 32a. On the other hand, the outer peripheries of the semi-parts 41, 41 are
e.

Reference numeral 41 'in the figure denotes a relief portion for accommodating a hinge when the middle screw member 4 is set in the outer shaft 1, and reference numeral 5 denotes a clip detachably provided on the outer shaft 1. 5 shows a cap with 51. In this embodiment, a description has been given of an example in which the pair of half parts 41, 41 constituting the middle screw member 3 are connected by the hinge 42. However, these half parts 41, 41 are completely independent and separated without the hinge 42. Of course, it may be formed as a part.

The above description has been made with reference to the direct filling type shown in FIG. 1, but FIG. 2 shows a cartridge type, and reference numeral 6 denotes a holder to which a bar is attached.
In FIG. 2, a rod-shaped object is provided so as to protrude from the center shaft 2 as compared with the direct filling type of FIG. 1.

Hereinafter, an assembling procedure will be described in order to better understand the structure of the rotary rod feeding device of this embodiment. First, the direct filling type of the rod-shaped material shown in FIG. 1 will be described. An oval insertion hole 2 formed in the bottom of the center shaft 2 will be described.
3 and the locking portion 32c of the slider 3 is inserted and inserted until it reaches the bottom surface of the receiving portion 31. Thereafter, the middle screw member 4 is set by pressing against the root of the shaft portion 32 of the slider 3. In this case, the pair of half parts 41, 41 have a corresponding locking projection 41b and locking recess 41c.
Therefore, since these are easily locked, the middle screw member 4 is securely attached to the slider 3.

Then, the assembly of the middle shaft 2, the slider 3, and the middle screw member 4 is inserted into the outer shaft 1 and set. In this case, since the middle screw member 4 is fixed to the polygonal portion 12 formed on the inner periphery of the outer shaft 1, the detent functions reliably thereafter. After that, filling the sticky material with the viscous material, the nozzle is positioned at the deepest part of the center shaft 2, and the filling is gradually finished while filling the sticky material with the viscous material, and the filling is completed. Fitting completes the assembly.

On the other hand, as for the cartridge type shown in FIG. 2, after the assembly of the center shaft 2, the slider 3 and the middle screw member 4 is inserted into the outer shaft 1 and set, the rod-shaped holder 6 with the holder is moved to the slider 3. If the cap 5 is fitted after setting in the receiving portion 31, the assembly is completed similarly.

Next, the operation of the rotor rod feeding device according to the embodiment of the present invention will be described. First, at the time of use, the cap 5 is removed, the outer shaft 1 is held and fixed, and the center shaft 2 is rotated. Then, the rotation of the center shaft 2 is transmitted to the slider 3 through the oval insertion hole 23 at the bottom thereof. Therefore, the slider 3 is provided with the female thread portion 41d of the middle screw member 4.
However, since the rotation is restricted by the middle screw member 4 fixed in the outer shaft 1, the rod rises and the rod-shaped object is fed.

After use, when the center shaft 2 is rotated in the opposite direction to the above, the bar is lowered and stored in the center shaft 2, so that the cap 5 must be covered so that the bar does not dry out. I can do it.

Further, since the center shaft 2 cannot be rotated by rotating the outer shaft 1 or the cap 5 with the cap 5 attached, the rod-like object rises with the cap 5 held, and the tip thereof is moved to the cap 5. It will not be damaged.

FIGS. 16 to 22 show another embodiment of the present invention. In the drawings, the structure for locking the middle screw member 4 and the outer shaft 1 is different from the above embodiment. That is, as is apparent from FIG. 18, fitting portions 41f having sharp edges 41g for guiding are formed at equal intervals in the width direction on the outer periphery of the middle screw member 4.

On the other hand, on the inner periphery of the outer shaft 1, there is formed a fitting portion 13 having a sharpened end 13a for guiding toward the opening direction of the outer shaft 1 corresponding to the fitting portion 41f of the middle screw member 4. . If the fitting portion 41f of the middle screw member 4 is formed with sharp ends 41g at both ends, it can be easily incorporated into the outer shaft 1 without considering the directionality of the middle screw member 4. . Reference numeral 41h in the figure is a recess for preventing sink marks during molding.

With such a configuration, the intermediate screw member 4 can be easily incorporated into the outer shaft 1 without requiring any directionality, and can be easily assembled. Further, it can be securely fixed after being assembled. is there.
