Abstract

PROBLEM TO BE SOLVED: To shorten a time necessary for changing bobbin type by preliminarily fitting a bobbin mounting adapter to both axial sides of a bobbin body, and linking the axial sides of the bobbin body to a winding machine or a delivery machine pintle via the adapter. SOLUTION: A small bobbin 10 is preliminarily provided with bobbin mounting adapters 31 and 41 on both axial sides. In the case of a large bobbin 20, bobbin mounting adapters 51 and 61 are preliminarily attached to both axial sides thereof. For fitting the bobbin mounting adapters 31, 41, 51 and 61, an adapter flange is kept in contact with the external surfaces of the collars of the bobbins 10 and 20, and detachably tightened with bolts or the like. For selecting the large bobbin 20 instead of the small bobbin 10, the dedicated bobbin mounting adapters 51 and 61 are preliminarily fitted, and a mounting work for the large bobbin 20 is carried out, similar to the case of mounting the small bobbin 10. According to this construction, a time required for changing bobbin type can be shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin mounting structure for a winder or a feeder using a bobbin.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional bobbin mounting structure in an uncompleted state, and FIG. 4 shows an example of the same bobbin mounting structure in a completely completed state.
The upper bobbin 10 and the lower bobbin 20 have a mounting structure on the upper side and the lower side of the horizontal center line, respectively.

In this conventional example, for example, the case of the upper small bobbin 10 will be described. A bobbin mounting adapter 3 and a bobbin mounting adapter 4 are provided in advance on a passive pintle 1 and a drive pintle 2 of a feeder or a winder, respectively. The small bobbin 10 is mounted between these bobbin mounting adapters 3 and 4. When the type of bobbin changes, the bobbin mounting adapters 3 and 4 are replaced each time the bobbin is mounted. The large bobbin 20 is also mounted in the same manner as above. Incidentally, 5 and 6 are large bobbin mounting adapters.

[0004]

According to the bobbin mounting structure of the prior art described above, it is necessary to replace each bobbin mounting adapter serving as an attachment on the feeder or winder side every time the type of bobbin is changed. The work was possible only when the feeder or the winder was stopped. Therefore, stopping the sending machine or the winding machine every time the bobbin is changed has been the biggest factor of lowering the operating rate.

Therefore, the problem to be solved by the present invention is to provide a bobbin mounting structure capable of minimizing the stop time of the feeder or the winder when changing the type of bobbin. .

[0006]

In the bobbin mounting structure provided by the present invention, bobbin mounting adapters are preliminarily mounted on both axial sides of the bobbin main body, and these adapters are provided on the winder or the feeder side. Since the bobbin is linked to the pintle, the bobbin can be changed without attaching the bobbin mounting adapter to the feeder or the winder.

[0007]

1 and 2 show a preferred embodiment of a bobbin mounting structure according to the present invention.
Shows the state where the mounting is not completed, and FIG. 2 shows the state where the mounting is completed. In each of the drawings, a case where the upper side is the small bobbin 10 and a case where the lower side is the large bobbin 20 are shown with the horizontal line at the center as a boundary.

According to this embodiment, the bobbin mounting structure is as follows. That is, for the small bobbin 10, the bobbin mounting adapters 31, 31 are provided on both sides in the axial direction of the small bobbin 10.
41 is mounted in advance, and the large bobbin 20 is configured such that bobbin mounting adapters 51 and 61 are mounted in advance on both axial sides of the large bobbin 20. The mounting of the bobbin mounting adapters 31, 41, 51, 61 is accomplished by applying the flange of the adapter to the outer surface of the collar portion of the bobbin 10, 20 and detachably fastening them with bolts or the like.

The bobbin, for example, the small bobbin 10 on which the bobbin mounting adapter is mounted as described above, is set at a predetermined position of the feeder or the winder, and the passive pintle 11 is pushed out to push one bobbin mounting adapter 31. To the other bobbin mounting adapter 41 by pushing out the drive pintle 21 by the pin coupling method. Then, as shown in FIG. It is used for sending out the take-up member and winding work on the bobbin.

Now, when changing from the small bobbin 10 to the large bobbin 20, the dedicated bobbin mounting adapters 51 and 61 are attached in advance, so that the appearance is the same as that of the small bobbin. As a result, the predetermined insertion work can be carried out, and the attachment of the sending machine or the winding machine or the like need not be replaced at all. Even for other types of bobbins, the bobbin can be mounted on the delivery machine or the winding side only by mounting a matching bobbin mounting adapter on the bobbin main body.

[0011]

According to the present invention as described above, it is possible to provide a bobbin mounting structure capable of minimizing the stop time of the sending machine or the winding machine when changing the type of bobbin. The intended purpose can be achieved.
Further, according to the present invention, the setup by the sending machine or the winding machine due to the change of the bobbin can be completely set up externally, the machine stoppage time is eliminated, and the machine operating rate is greatly improved.
