Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a manufacturing process such as filling a container with cosmetics or the like.
The present invention relates to a container holder for holding a container that circulates on this line.

[Conventional technology]

Generally, when a tube-shaped container is filled with a cosmetic or the like on a production line, the container is held by a holder set on the line and circulating. As a holder of this kind, it has come to be used not only for filling but also for supporting a container in an automated work such as changing the direction of the container and printing or labeling on a predetermined surface.

As described above, in the case of a container holder used for several kinds of working processes, in the molding process using a normal synthetic resin material, the difference in the dimensional tolerances set on the holder side and the container side is the dimensional difference between the two. Clearance occurs. If this clearance is large and rattling occurs, the following various problems will be caused. That is, the holder scratches the side of the container.

・ The production line cannot operate at high speed.

・ The container may come out of the holder and scatter.

・ Noise is loud during operation due to rattling.

-The detection of the container position by the sensor for controlling the direction rotation of the container is incorrect.

And so on.

Therefore, in order to solve such a problem, it is preferable that the holder has a structure capable of absorbing the accuracy error due to the tolerance dimension on the container side of the partner.

As an example, FIG. 5 shows a tube container holder described in Japanese Utility Model Laid-Open No. 61-144008, which is proposed based on the above circumstances. As for the outline of this holder, the holder main body 1 for holding the container C is equally divided in the circumferential direction, and a chuck 2 as a holding member is provided slidably in the radial direction at each of these positions. Also, each of these chucks 2
Is urged by the elastic force of a spring (not shown) in a direction of reducing the diameter toward the center of the holder, and freely supports a plurality of types of containers C having different outer diameters, and holds and holds the outer peripheral surface. Therefore, each chuck 2 has a structure that expands and contracts in the radial direction.

[Problems to be solved by the invention]

However, as is clear from the figure, this tube container holder is composed of a sliding member including the chuck 2 and members such as a spring that biases the chuck 2 toward the center of the holder. Is complicated and extremely high processing accuracy of the member is required.

If a large number of such tube container holders are required for mass production on a production line, there is a problem in that the cost will rise.

Furthermore, in the process of printing on the predetermined surface of the container,
A container holder capable of preventing not only holding the container but also rotating the container to be held because it is necessary to prevent the container fixed to the holder from rotating, not only holding the container C. Was strongly requested.

The present invention has been made in view of the above problems of the conventional example, has a very simple structure, can hold a plurality of types of containers having different sizes, and holds the containers. An object of the present invention is to provide a container holder capable of preventing rotation of the container.

[Means for solving problems]

In order to achieve this object, the container holder of the present invention has the following structure.

That is, forming the base 10 to be attached on the distribution line,
A sandwiching portion 11 is integrally formed in a cylindrical shape on the upper portion of the base portion 10.

Then, from the peripheral edge of the opening, the base 10
A plurality of vertically divided slits 12 are provided toward.

Further, a recess 15 is formed at the bottom of the holding portion 11, and a slip stopper 13 that prevents the container from rotating by friction with the container is fitted and fixed in the recess 15.

In the container holder of the present invention, by forming a plurality of slits 12 in the holding portion 11, the holding portion 11 is provided with an elastic force capable of expanding and contracting the diameter in the radial direction as a whole.

Here, when the holding section 11 has a circular cross-sectional shape, the slits 12 are respectively provided from positions where the circumference is equally divided.
In the case of an elliptical shape, a slit is formed between the major axis and the minor axis.
The 12 pitches may be different.

[Action]

In the container holder of the present invention, when holding the container C having an outer peripheral diameter larger than the inner peripheral diameter in the holding portion 11, the holding portion 11 expands in the radial direction by the elastic action by the difference in diameter. Since the elastic contracting force that restores the original shape when the diameter is reduced is applied to the expanded holding portion 11, the container C is held by the holder in a tightened state.

Therefore, even if there is some dimensional accuracy error on the container C side,
The gripping portion 11 freely absorbs and absorbs this error, and also expands and contracts a wide variety of containers C having different outer diameters.

Further, in the container holder of the present invention, a recess is formed at the bottom of the holding portion 11, and a slip stopper 13 that prevents the container from rotating by friction with the container is fitted and fixed in this recess. Therefore, the container held in the container holder is prevented from unnecessarily rotating in the container holder. by this,
When the direction change control is performed by the position detection by the sensor in the process of printing on the predetermined surface of the container C, etc., not only by simply holding the container C, the container C is rotated by rotating the container holder. It becomes possible to rotate it accurately.

〔Example〕

Hereinafter, embodiments of the container holder according to the present invention will be described with reference to the drawings.

FIGS. 1 and 2 (a) and (b) show a first embodiment of the present invention for holding, for example, a bottle-shaped container C in an upright state.

That is, the holder H for holding the container C is made of a synthetic resin material such as nylon, neurite, Delrin, etc. The holder H has a base portion 10 provided at the lower portion of the holder recess 10a.
Then, it is attached to a chuck (not shown) on the production line by means of magnetic adsorption or the like, holds the container C and circulates on the production line.

In addition, a cylindrical holding portion 11 is integrally formed on the upper portion of the base portion 10 with its opening peripheral end facing upward.

A plurality of slits 12 are formed in the holding portion 11 from the peripheral edge of the opening toward the base portion 10 at equal intervals in a vertically divided shape, and by the formation of the slits 12, the entire holding portion 11 is expanded and contracted in the radial direction. An elastic force is given so that the diameter can be increased. As shown in the figure, the shape of the cross section is
11a and the thick portion 11b are provided in series and bent so that the container C can be effectively held. Further, in consideration of various bottle-shaped containers C having different sizes, a device is devised so that play between them and the outer peripheral surfaces thereof is minimized.

A recess 15 is formed on the bottom surface of the holding unit 11, which is also the upper surface of the base 10, and an annular slip stopper 13 made of a rubber material is fitted and fixed in the recess 15. As a result, when the bottle-shaped container C is held by the holding portion 11, the bottom of the container C abuts on the slip stopper 13 and the container C held by friction with the slip stopper 13 does not easily rotate. It is like this.

Next, another embodiment of the present invention will be described.

In the following description, the parts denoted by the same reference numerals as those in FIGS. 1 and 2 have the same configurations as those in FIGS. 1 and 2, and thus detailed description thereof will be omitted.

3 (a) and 3 (b) show a second embodiment of the present invention. The container holder H of the second embodiment is used in the process of filling a tubular container with a kneaded product such as cosmetics, when the container is held upside down without being sealed at its rear end. To be The base 10 of the container holder H is formed with a stepped portion 14 penetrating in the longitudinal direction.
With the tube container C inverted, the cap screwed to the mouth and neck is dropped and held.
The structure of the holding part 11 is the same as that of the first embodiment.
In the second embodiment, the recess 15 and the slip stopper 13 fitted and fixed to the recess 15 may be provided on the upper surface of the stepped portion 14 or on the lower surface thereof.

Further, FIG. 4 shows a third embodiment in which the holding section 11 of the container holder H of the first and second embodiments has an elliptical cross section in plan view. In this case, the pitch of the slits 12 provided from the peripheral edge of the opening may be unequal intervals corresponding to the cross-sectional strength performances on the major axis side and the minor axis side, or may be provided at regular intervals as usual.

Therefore, when the container C is dropped into the container holder H according to the first, second, and third embodiments, the holding portion 11 of the container holder H is elastically expanded by the action of the slit 12 in the radial direction to try to restore. The container C is held by the elastic contraction force. At this time, the container C is firmly held by being held by the holding portion 11 and frictional force with the slip stopper 13.

As a result, in the case where the container C is rotated and the positioning is controlled in each manufacturing process such as filling in the container C and printing, the container C reliably held in the container holder H.
On the other hand, it is possible to perform the positioning control by rotating the container C with high accuracy.

[Effect of device]

As described above, in the container holder according to the present invention, the holding portion for holding the container has a simple structure in which vertical slits are simply provided at the peripheral edge of the opening at equal intervals. It does not require a mechanism with a complicated and high processing accuracy such as the sandwiching structure. Moreover, not only is it possible to absorb the accuracy error due to the tolerance dimension on the container side, but it is also possible to accommodate a plurality of types of containers having different diameters within a considerable range.

In addition, since the rattling can be eliminated, the side surface of the container is not scratched by the conventional container holder, high-speed operation of the manufacturing line is enabled, and the container can be prevented from falling out and scattering. Further, it is possible to suppress the generation of noise during operation due to rattling, which is excellent in various practical effects.

Further, by providing a slip stopper for preventing the container from rotating due to friction between the container and the container, it is possible to prevent the container held in the container holder from rotating unnecessarily, and to prevent a predetermined surface of the container from rotating. By rotating the container holder in the process of printing or the like, the container can be accurately rotated.
