Abstract

PURPOSE: To immediately and correctly take off an end part of a sliver in a can by providing a locking mechanism which is provided with a side wall and a bottom wall, and holds the end part of the sliver at the predetermined position on an upper edge of the side wall. CONSTITUTION: A can 10 comprises a side wall S and a bottom wall B, and is of approximately rectangular section. The side wall S has a pair of long upper edges and a pair of short upper edges 12. A notch 13 to hold an end part of the sliver to be stored in the can 10 is formed on the upper edges. The action in the transverse direction of the end part of the sliver taken out of the can 10 toward the upper edges is limited, and the end part of the sliver is held at the predetermined position. The shape of the notch 13 can be rectangular 113, semi-circular 213, V-shaped 313, etc.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can for holding sliver. More particularly, the invention relates to a can having a mechanism for holding the ends of the sliver in place.

0002

BACKGROUND OF THE INVENTION Cans for holding sliver from a drawing machine and feeding it to an open-end spinning machine have a circular cross section, the diameter of which is varied depending on the spacing between the spinning units.

[0003] Cans having an elongated cross section, ie, cans having a rectangular, elliptical or oval cross section, are also known.

Cans with an elongated cross-section are suitable for application in automatic devices for replacing cans full of sliver on a spinning unit with empty cans. The reason for this is that such cans have a large transverse capacity and can accommodate a large amount of sliver, which not only allows them to feed sliver to the spinning unit without having to arrange them in multiple rows like cans with a circular cross section, but also allows automatic This is because it can be easily handled by the exchange device.

[0005]

SUMMARY OF THE INVENTION The can of the present invention can be modified in various shapes and dimensions to include a dispensing device for automatically distributing the sliver in the can and an automatic device that engages with the sliver and guides the sliver to the spinning unit. It can be made compatible with the device. The technique of the present invention is applicable to many types of cans for holding sliver for textiles, which have different shapes and dimensions.

The can of the invention has on its upper edge at least one locking mechanism for holding the end of the sliver contained in the can in a predetermined position. The position of the end of the sliver is maintained by constraining the lateral movement of the sliver by the locking mechanism. This locking mechanism allows the end of the sliver in the can to be picked up quickly and accurately. This is independent of whether the cans are handled manually or by automatic equipment.

[0007] This locking mechanism may be formed by machining a part of the can, or may be attached to the can as a separate body. The upper edge of the can used in the present invention consists of a pair of long edges and a pair of short edges, and the locking mechanism is formed on at least one of the short edges. Ru.

To the best of the knowledge of the applicant of the present invention, there is no can that can exhibit effects equivalent to those of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, a first embodiment of the present invention will be described based on FIGS. 1 to 3. The can 10 is composed of a side wall S and a bottom wall B, and has a substantially rectangular cross-sectional shape. Side wall S
are a pair of longer upper edges 11 and a shorter pair of upper edges 1
2. And this can 1 is placed on the upper edge 12.
A notch 13 is formed for holding the end of the sliver received within the sliver. This notch 13 limits the lateral movement of the end of the sliver drawn out of the can towards its upper edge and holds the end of the sliver in a predetermined position. The shape of this notch is 11 in Figure 1.
3, 213, and 313, various shapes can be used, such as rectangular, semicircular, and V-shaped.

Next, a second embodiment of the present invention will be explained based on FIGS. 4 to 6. The can 20 consists of a side wall S and a bottom wall B, and has a substantially elliptical cross-sectional shape. Side wall S
has a pair of long straight upper edges 21 and a pair of short curved upper edges 22. And the upper edge 22
A spout 24 for holding the end of the sliver contained in the can 20 is formed on one side of the can. This spout 24 further has a groove 25 formed therein. This groove 25 holds the end of the sliver drawn out of the can towards its upper edge in a predetermined position. Note that the cross-sectional shape of this groove 25 is 125 and 22 in FIG.
As shown in 5, it can be made into various shapes such as a rectangle and a semicircle.

Next, a third embodiment of the present invention will be explained based on FIGS. 1 to 3. The can 30 is composed of a side wall S and a bottom wall B, and has a substantially rectangular cross-sectional shape. Side wall S
are a pair of longer upper edges 31 and a pair of shorter upper edges 3
2. And this can 3 is placed on the upper edge 32.
A pair of protrusions 36 are formed for holding the ends of the sliver contained within the sliver. This protrusion 36 holds in a predetermined position the end of the sliver drawn out from the can towards its upper edge.

Finally, a fourth embodiment of the present invention will be explained based on FIGS. 10 to 12. The can 40 consists of a side wall S and a bottom wall B, and has a substantially elliptical cross-sectional shape. The side wall S has a pair of long straight upper edges 41 and a pair of short curved upper edges 42. A pair of protrusions 47 are formed on the upper edge 42 to hold the ends of the sliver accommodated in the can 40. This projection 47 holds the end of the sliver drawn out of the can towards its upper edge in a predetermined position.

The embodiments described above are merely illustrative and do not limit the invention. Therefore, this invention can be implemented in any form without departing from its spirit and scope.
