Description

[Detailed description of the invention] (Industrial application field) This invention is a bobbin for winding synthetic fiber yarn or other winding bobbins to be held in a winding transport vehicle, etc. It is related to the arm.

(Prior art) A wound package obtained by winding synthetic fiber yarn discharged from a spinneret with a winder below the spinneret has its surfaces in contact with each other and with other machine parts. In order to avoid this, a large number of arms made of pipes are installed horizontally in multiple rows and in multiple stages on a wall-like frame that stands upright on the yarn transport vehicle.
A plurality of thread bobbins were inserted into each arm.
In order to prevent the winding bobbin fitted into the arm from falling off due to vibration during transportation,
The outer surface of the arm and the inner surface of the winding bobbin were tightly fitted.

(Problem to be solved by the invention) Conventionally, the outer surface of the arm and the inner surface of the winding bobbin were tightly fitted, and a large amount of force was required to attach and detach the winding bobbin. When the winding bobbin (paper tube) was automatically pushed out and inserted into the arm of the carrier, the paper tube was sometimes obstructed from entering. Also, when pulling out the thread bobbin on the arm, the thread layer gets in the way and you cannot grasp the paper tube with your hands. After reaching the free end of the arm, a hand is inserted into the paper tube to take out the thread package, which causes problems such as the surface of the thread package becoming dirty and the shape of the thread package being distorted.

This invention makes it possible to reduce the sliding resistance of the thread bobbin relative to the arm, and also to make it possible to remove the thread package on the arm without touching it.

(Means for Solving the Problems) As shown in FIG. 1, the arm 10 of this invention has a pipe 1 supported almost horizontally provided with a slot 2 extending from the vicinity of its base to a free end, and a pipe 1 It is characterized in that a thin guide bar 3 is fixed to the outer surface of the slot 2 along both edges of the slot 2. In addition, in FIG. 1, 4 is a bobbin, 5 is a winding layer, and 6 is a wall-shaped frame.

(Function) The bobbin 4 has two guide bars 3, 3 upper surfaces,
It contacts the arm 10 at three points in total, including the opposite surface of the pipe 1 when viewed from the slot 2, and connects the bobbin 4 and the pipe 1.
Since a wide gap is formed between the pipe 1 and the pipe 1, and the slot 2 is formed in the pipe 1, the edge of the slot 2 is easily deformed elastically in the radial direction, so the sliding resistance of the bobbin 4 is reduced. do. Further, the presence of the slot 2 allows the operator to insert his hand into the pipe 1 and hold the bobbin 4 with his hand.

(Example) As shown in FIG. 2, a wall-like frame 6 is vertically installed on one side of a chassis 7 having wheels 8, and a large number of arms 10 are mounted on this wall-like frame 6 in multiple rows and stages. and protrude horizontally. However, the vertical and horizontal intervals of the arm 10 were set so that the thread layers 5 did not come into contact with each other, and the length of the arm 10 was set to such an extent that two bobbins 4 could be inserted in this embodiment. As shown in FIG. 1, a slot 2 is formed in the upper surface of the pipe 1 constituting the main body of the arm 10, and round guide bars 3 are fixed to both side edges of the slot 2 by welding.

In this embodiment, since the slot 2 is provided on the upper surface of the pipe 1, the slot 2 is easily visible and the bobbin 4 can be easily attached and detached. A stopper that engages with the bobbin 4 is provided on the base side of the pipe 1 so as to be located slightly in front of the end of the slot 2, and when the bobbin 4 is pushed in until it hits this stopper, the end of the slot 2 If there is a gap in which the worker's finger can be inserted, the finger inserted into this gap will be inserted into the bobbin 4.
The bobbin 4 can be pulled out more easily by hooking it on the bobbin 4.

(Effects of the invention) This invention forms a slot in the pipe and fixes a thin guide bar along the edge of this slot to form an arm for inserting the bobbin, reducing the sliding resistance of the bobbin. This allows you to insert your hand into the pipe and hold the end of the bobbin, which makes it easy to attach and remove the bobbin, and eliminates the need to touch the thread layer on the bobbin, which prevents dirt on the thread layer. is resolved.
