Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin feeding device, more specifically, a bobbin feeding device used for supplying a full bobbin of a material wire to a twisting machine or a collecting machine, or collecting an empty bobbin from them. It relates to the feeding device.

[0002]

2. Description of the Related Art Conventionally, there is no special machine for supplying a fully wound bobbin of a twisted wire as a material to a cable collecting machine, and a required number of fully wound bobbins are kept near the machine and individually supplied. The collection of empty bobbins was also done individually.

[0003]

Therefore, in the case of a large assembly machine using a large number of bobbins, bobbin replacement becomes complicated, which not only lowers manufacturing efficiency but also secures a space in the vicinity of the assembly machine. It also hinders the transportation of other goods, and there has been a demand for some kind of measure in terms of factory management as a whole.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the means for solving the problems are such that they are opposed to each other at a predetermined interval and are in the vertical plane. Between a pair of opposed closed-loop pallet feed chains that are hung on four chain sprockets provided at respective apexes of a pair of parallelograms of the same shape that are parallel to each other, and between the pallet feed chains. A plurality of pallets that are rotatably mounted via a support shaft and have a bobbin mounted on the upper surface, and a predetermined number of pallets that are provided at corresponding positions outside the pallet feed chain and that are separated in the traveling direction. A bobbin feeding device having at least one closed-loop type pallet posture control chain in which a part of each pallet is connected to a position.

[0005]

[Function] Since the pallet feed chain is a closed loop type, it can circulate between the full bobbin supply starting point (which also serves as the empty bobbin collecting position) and the bobbin mounting machine. The bobbin is fed and, conversely, the empty bobbin is collected and transferred from the bobbin machine to the supply start point. The pallet attitude control chain holds the pallet in a horizontal attitude suitable for placing the bobbin.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. First, set one parallelogram with vertical faces, and set sprocket 4A, 4 at these four vertices, respectively.
B, 4C and 4D are rotatably provided in the vertical plane, and a pallet feed chain 2A forming a closed loop is constructed by being wound around these sprockets 4A, 4B, 4C and 4D.

Next, another parallelogram which has the same shape as the above parallelogram and which is parallel to the parallelogram at a predetermined distance determined from the relationship described later is set so as to correspond to each other. Sprockets 4A, 4B, 4C,
Similarly, 4D is rotatably provided in the vertical plane, and a pallet feed chain 2B forming a closed loop is formed by being wound around each of these sprockets 4A, 4B, 4C, 4D.

In the flat pallet 1 on which the bobbin B1 and the like are to be placed, the support shafts 11 extending laterally on both sides of the center thereof are mounted on the support brackets 21 provided in the pallet feed chains 2A and 2B at appropriate intervals in the longitudinal direction. A desired number of each is rotatably mounted so as to be rotatably inserted. The above-mentioned predetermined interval between the pallet feed chains 2A and 2B means a necessary and sufficient interval for arranging the pallet 1.

Outside one (or both) of the pallet feed chains 2A and 2B, a parallelogram having a vertical plane of the same shape as the parallelogram is shifted upward or downward (downward in the illustrated embodiment). 4 sprocket 6 which are set to be rotatably provided at each vertex of the quadrangle.
A pallet posture control chain 3A (and / or 3B) that is wound around A, 6B, 6C, and 6D to form a closed loop is configured.

An attitude control arm 31 is fixed to one end (or both ends) of the support shaft 11 of the pallet 1, and the end of the attitude control arm 31 is attached to the pallet attitude control chain 3A (and / or 3B). Be connected. With this configuration, the attitude control arm 31 is rotated by the movement of the pallet attitude control chain 3A, and the pallet 1 can be arbitrarily tilted including the horizontal attitude. If a pallet attitude control chain 3B is also provided separately, it goes without saying that both pallet attitude control chains 3A and 3B must be controlled so that they simultaneously move in the same direction and at the same speed.

In FIG. 1, reference numeral 5 as a whole is a bobbin lifting device which can be used together with the device of the present invention. In this case, as shown in detail in FIG. 4, end members 52 that can be raised and lowered by a lift cylinder 51 are arranged at both ends, and two opening / closing cylinders 53A and 53B are provided at substantially the center of the end members 52 with their cylinder rods. Is provided coaxially so that the direction of extension and retraction of the same coincides with the longitudinal direction of the end member 52.

Two carrying bars 54A and 54B are attached to the end of the cylinder rod, and the carrying bars 54
A and 54B have clamping shafts 5 at desired plural positions in the longitudinal direction.
5 are provided so as to face each other and project. That is, the holding shaft 55 projects from both sides by the operation of the opening / closing cylinders 53A and 53B, and is provided at the tip of the holding shaft 55.
For example, each bobbin B1, B
The configuration is such that 2, ... Can be sandwiched.

The operation of the device of the present invention will be described. As a matter of course, the pallet feed chains 2A and 2B are controlled so as to always move in the same speed and in the same direction. As a result, each pallet 1 that is supported by the support shaft 11 between the pallet feed chains 2A and 2B is conveyed in the moving direction of the pallet feed chain.

At this time, the pallet attitude control chain 3A
(And / or 3B) is also controlled so as to move in the same speed and in the same direction as the pallet feed chain 2A and the like. In this way, the position control arm 31 can convey the pallet 1 while keeping the pallet 1 in the horizontal posture as shown in FIG. For example, in this way, several empty bobbins B1, B2, ... Located in the upper part of FIG.
It is possible to perform the operation to switch to 2, ... at once.

The pallet attitude control chain 3A causes the position control arm 31 to rotate either clockwise or counterclockwise by being operated when the pallet feed chains 2A and 2B are stopped. It is self-evident that the pallet 1 can be tilted in any direction and at any angle. This can be used, for example, when the pallet 1 is tilted at the empty bobbin stacking position to take out the empty bobbin.

The parallelogram in which the chain sprockets at the four corners of the pallet feed chains 2A and 2B are arranged is shown in FIG.
In the embodiment, the upper and lower sides are horizontal rectangles, but the present invention is not limited to this. For example, the upper and lower two sides are short, and the left and right two sides are long. Good. The point is that the bobbin can be configured in any shape depending on the positional relationship between the storage location of the bobbin and a machine such as a collecting machine that uses the bobbin.

[0017]

According to the present invention, since the pallet feed chain is of the closed loop type, it is possible to circulate between the full bobbin supply starting point (also serving as the empty bobbin collecting position) and the bobbin mounting machine, whereby the bobbin is supplied from the supply starting point. There is an effect that the full bobbin can be fed to the mounting machine and, conversely, the empty bobbin can be collected and transferred from the bobbin using machine to the supply starting point.
Further, at this time, the pallet posture control chain has the effect of holding the pallet in a horizontal posture suitable for bobbin transfer or tilting the pallet at a desired angle for the purpose of accumulating empty bobbins.
