Description

Adapter and package replacement device

Technical Field

One embodiment of the present invention relates to an adapter and a package replacement device.

Background

As a conventional package replacement apparatus, for example, an apparatus described in patent document 1 (japanese patent application laid-open No. 4-66479) is known. The package replacement device described in patent document 1 is a device for replacing a package on a bobbin provided in a creel, and includes a travel device for traveling along the creel, a setting device for replacing a package on the bobbin (corresponding to english: peg), and a splicing device (splicer for synthetic fiber yarn) for splicing yarns of two packages to each other. The setting device and the joint device are arranged on the base of the running device.

In the splicer for synthetic fiber yarns, the yarn on the outer layer side of one package is spliced with the yarn on the inner layer side of the other package. In this case, yarn ends of the yarns on the outer layer side and the inner layer side of the package are difficult to catch, and as a result, for example, it may become difficult to guide the yarns to the splicer for the synthetic fiber yarns.

Disclosure of Invention

An object of one embodiment of the present invention is to provide a yarn end splicer and a package replacement device that can easily capture yarn ends on the outer layer side and the inner layer side of a package.

An adapter according to an aspect of the present invention is an adapter attached to a package having a yarn made of synthetic fiber, comprising: an installation part which is installed on the bobbin of the package in a synchronous rotation mode; a first holding portion provided in the mounting portion and holding yarn ends of the yarn on the outer layer side of the package; and a second holding portion provided in the mounting portion and holding yarn ends of the yarn on the inner layer side of the package.

By using this adapter, the yarn on the outer layer side of the package can be held in advance by the first holding portion, and the yarn on the inner layer side of the package can be held in advance by the second holding portion. Therefore, the yarn ends of the yarns on the outer layer side and the inner layer side of the package can be easily caught.

In the adapter according to one aspect of the present invention, the attachment portion may have an annular outer ring portion covering the outer peripheral surface of the bobbin with a gap therebetween, and the yarn on the inner layer side of the package may be wound around the outer ring portion. In this configuration, the outer circumferential surface of the bobbin can be protected from damage by the outer ring portion. Further, since the yarn on the inner layer side of the package is wound around the outer ring portion, for example, a sufficient yarn length for splicing or the like by the splicer for synthetic fiber yarn can be ensured.

In the adaptor according to an aspect of the present invention, the first holding portion may include: a first arm, the base end side of which is fixed to the mounting portion; a first grip provided on the front end side of the first arm and gripping yarn ends of the yarn on the outer layer side of the package; and a first yarn guide for hooking at least the yarn on the outer layer side of the package. According to such a first holding portion, the yarn end of the yarn on the outer layer side of the package can be held appropriately, and the positional relationship of the yarn from the package to the yarn end can be set to a predetermined position.

In the coupling according to an aspect of the present invention, the second holding portion may include: a second arm, the base end side of which is fixed to the mounting portion; a second grip provided on the front end side of the second arm and gripping yarn ends of the yarn on the inner layer side of the package; and a second yarn guide for hooking the yarn on the inner layer side of the package. By such a second holding portion, the yarn end of the yarn on the inner layer side of the package can be held appropriately, and the positional relationship of the yarn from the package to the yarn end can be set to a predetermined position.

In accordance with one aspect of the present invention, a package replacement apparatus includes: a splicer for synthetic fiber yarns, which is used for jointing yarns of one package and the other package with the splicer; and a yarn catching and guiding part for catching and guiding the yarn end of the yarn held by the first holding part of the splicer mounted on one package to the splicer for the synthetic fiber yarn and catching and guiding the yarn end of the yarn held by the second holding part of the splicer mounted on the other package to the splicer for the synthetic fiber yarn.

In this package replacement apparatus, since the above-described adapters are attached to one package and the other package, yarn ends of yarns on the outer layer side and the inner layer side of the one package and the other package can be easily caught by the yarn catching guide. In addition, the yarn can be easily guided to the splicer for the synthetic fiber yarn.

According to one aspect of the present invention, it is possible to provide a yarn end splicer and a package replacement device that can easily capture yarn ends on the outer layer side and the inner layer side of a package. According to one aspect of the present invention, a package replacement device capable of easily guiding a yarn to a splicer for a synthetic fiber yarn can be provided.

When the joining operation is started, the joining device 60 operates the first bobbin 24a by the first rotating mechanism 62 and operates the second bobbin 24b by the second rotating mechanism 63, and rotates the splicer 10 to a position where the first yarn end Y1 and the second yarn end Y2 can be caught by the suction portion 61a, as shown in fig. 14. Specifically, in the first rotation mechanism 62, the first joint driver 62a is engaged with the first wheel 25j of the first bobbin 24a, and the first motor 62b is driven to rotate the first joint driver 62 a. Similarly, in the second rotating mechanism 63, the second joint driver 63a is engaged with the first wheel 25j of the second bobbin 24b, and the second motor 63b is driven to rotate the second joint driver 63 a.

An adapter attached to a package having a yarn made of synthetic fibers, comprising: a mounting part which is mounted on the bobbin of the package in a synchronous rotation manner; a first holding portion provided in the mounting portion and holding yarn ends of the yarn on the outer layer side of the package; and a second holding portion provided in the mounting portion and holding yarn ends of the yarn on the inner layer side of the package; the mounting portion has an annular outer ring portion covering an outer peripheral surface of the bobbin with a gap therebetween in a radial direction of the bobbin, and the yarn on an inner layer side of the package is wound around the outer ring portion.

2. The adaptor according to claim 1, wherein the first holding portion has: a first arm having a base end fixed to the mounting portion; a first grip provided on a distal end side of the first arm and gripping yarn ends of the yarn on an outer layer side of the package; and a first yarn guide for hooking at least the yarn on the outer layer side of the package.

3. The adaptor according to claim 1 or 2, wherein the second holding portion has: a second arm having a base end fixed to the mounting portion; a second grip provided on the distal end side of the second arm and gripping yarn ends of the yarn on the inner layer side of the package; and a second yarn guide for hooking the yarn on the inner layer side of the package.

4. A package replacement device is provided with: a splicer for synthetic fiber yarns, which performs a splice of one package and another package to which the splicer according to any one of claims 1 to 3 is attached; a yarn catching and guiding unit that catches yarn ends of the yarn held by the first holding unit of the splicer attached to the one package and guides the yarn ends of the yarn held by the second holding unit of the splicer attached to the other package to the splicer for synthetic fiber yarns; and a rotation mechanism for rotating the one package and the other package around the axis of the bobbin.
