Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a bobbin hanger, and in particular, to a bobbin hanger that can reliably attach and detach a hanging Shinomaki bobbin with a short push-up operation distance, and a bobbin hanger that has a thick empty frame for attaching the bobbin and a bobbin length. Even for long objects, the conventional creel device can be used as is.
This article relates to a bobbin hanger that can be used.

Various types of bobbin hangers (bobbin holders) have been used and proposed in order to attach a shinomaki to a spinning machine or a mechanical device attached thereto. In most of these, the stepped mounting hole formed at the top of the bobbin bottoms out into the outer circumference of the supporting cylinder of the bobbin hanger, and the stepped mounting is done by a claw protruding from the supporting cylinder towards the outer circumferential side. It is configured to be suspended and supported by engaging the small diameter stepped portion of the hole, and is attached and detached by pushing up the bobbin to operate the claw piece. FIG. 1 (side view) shows an example of a bobbin hanger that is generally widely used. Skirt club month 5. Mounting body part 8
and a bobbin support cylinder 4, and the mounting body 8 is attached to the screw shaft 2.
It is supported by a ball bearing at the bottom so that it can rotate freely and is allowed to swing slightly, and a skirt member 5 of the hanging bell is attached to the side of the screw shaft 2 so as to cover this support part. The bobbin support cylinder 4, which has a length of 11 inches, is attached to the F of the mounting body 3.
1 which is attached to the part and freely descends around it.
Gen6 is set so that it does not rotate. 1. The bobbin support cylinder 4 is formed in a hollow shape, and an elevating member that is moved up and down only by the pushing up action of the mf gear 6 is slidably housed in the hollow portion, and the lower part of the elevating member is slidably housed. It supports claw pieces 7, 7a which can be opened and closed freely. In addition, on the upper side of this elevating part H, there is provided a watch member which is rotated 90 degrees for every two elevating operations. A retaining piece is formed within the bobbin supporting cylinder 4 to lock and hold the raised and lowered positions h, and each time the front line 6 pushes up, this retaining piece forms a raised and lowered position within the bobbin support cylinder 4. The holding and securing portions are engaged with each other alternately. When the elevating member is in the ascending position of 1 m, the claw pieces 7 and 7a are housed in the bobbin supporting cylinder, and in the descending position, the claws 7 and 7a are formed 11"q so as to protrude as shown and support the bobbin 8. That is, In most bobbin hangers, the mFIlj6 is pushed up by the bobbin 8, the claw pieces 7.7a are made to project outside the bobbin support cylinder 4, the bobbin 8 is suspended, and the next push-up action causes the claw pieces 7.
, 7a are housed in the bobbin support cylinder 4 and the bobbin 8 is removed, and it is necessary to slide the elevating member a considerable distance in response to the protrusion and storage of the claw pieces 7, 7a. I couldn't shorten the number 4.

In addition, a considerable distance of movement is required to rotate the elevating member and the check member, and the mounting body 8 must also be formed long.

The center portion thereof is pivoted to the lower side of the bobbin support cylinder 4, and the short axis and long axis of the fluorescent plate claw are alternately displaced by the upward movement of the weight 6, and the long axis is moved relative to the bobbin support cylinder. There is also a method in which the bobbin 8 is suspended by a 4jdLM held perpendicularly to each other, but it requires a long travel distance of one centimeter to rotate the claw piece, and the bobbin support cylinder cannot be shortened. . In addition, recently, Shinomaki has been made into a warge package and long bobbins have been used, and it has become necessary to configure the creel device on the back, but it has become inconvenient to attach and remove the Shinomaki. It consists of a short bobbin support cylinder and flH
The claw bobbin stage (
The bobbin hanger is reliable because it can be used to fix defects and the claws have a strong supporting force.

The present invention has been made with attention to these points, and in particular improves the configuration and operating mechanism of the claw pieces provided in the bobbin support cylinder, so that even if the distance 11iJl of the upward movement of the cloth by the inserted bobbin is shortened, the claw pieces can still be maintained. It is constructed so that it can be reliably protruded and retracted, and the suspension force is directly applied to the bobbin support cylinder. However, in the present invention, the lower sides of two bobbin locking pawl pieces are each pivoted on a single shaft at a lower position within the bobbin support cylinder, and the pawl pieces are attached to the shaft from the shaft support. A hole is formed in the upper phase for engagement, and a supporting shaft installed on the lower side of the elevating member is engaged with the retaining groove, and when the JA descending member is in the elevated holding position, the tip of each claw piece is is housed in the bobbin support cylinder, and the tips of the claw pieces are respectively projected outside the bobbin support cylinder in the lowered holding position.

The present invention will be described in detail below with reference to the drawings, but the drawings show an example of a specific embodiment in which the present invention is applied to an example of a bobbin hanger.1 The present invention is not limited to these illustrated examples, and・A configuration in which the shapes of the constituent members are changed in accordance with the purpose described later can have the same effect (■) even if a part of the design is changed. Fig. 2 (side view) shows a configuration in which the present invention is applied. This shows the constructed bobbin hanger IR.In particular, for comparison with Figure 1, it shows 1&D with bobbin hanger 1a attached to the same frame and bobbin 8 suspended in the same way as in Figure 1. That is, in the bobbin hanger 1a of the present invention, the claw pieces 9, 9a can be reliably projected even if the bobbin support cylinder 4 is shortened, and the height at which the bobbin 8 is suspended and supported can be increased by 40 m or more. , long bobbin 8f: Even if a long bobbin 8f is used, the bobbin hanger l& can be installed at the same height position of the conventional creel device.Also, if the bobbin is the same length, the installation position of the bobbin hanger 1a can be lowered. This allows the creel device to be lowered, making it easier to attach and detach the bobbin.
