Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention involves feeding a winding bobbin for a linear material one after another to a winding position, holding the bobbin between a driving pintle and a driven pintle, and rotating the bobbin. This type of bobbin is wound onto the body of the bobbin via a traverser, and when it is fully wound, the winding end is cut off, the fully wound bobbin is carried out of the machine, and the next empty bobbin is sent to the winding position. An automatic wire winding device that securely holds the cutting end, chucks it to the bobbin side, and stores the end in a rotating wheel on the pintle side to enable smooth automatic winding. Regarding.

(Prior art) Empty bobbins are sequentially delivered to a winding position where a driving pintle for clamping and rotating the bobbin and a driven pintle are arranged rotatably and freely forward and backward, and a traverser that can freely move back and forth in parallel with the bobbin axis direction is provided. A wire material clamp and cutting cutter that can be opened and closed when the bobbin is fully wound, and an extrusion device that pushes out the wire material that passes between the fully wound bobbin side and the traverser to the clamp and cutter side. An automatic winding device for a linear material that is cut by a member is disclosed in, for example, Japanese Patent Application Laid-Open No. 1987-
It is known as seen in Publication No. 114265. In such conventional technology, when the wire is fully wound, the part of the wire extending from the fully wound bobbin side to the traverser side is made into an overhanging shape by an extrusion member, and the wire is gripped by a wire material clamp that can be opened and closed. After cutting the linear object part in front of the part with the cutting cutter, the clamp is rotated toward the linear object pinching member provided on the drive pintle on the empty bobbin side, and the cut end is passed to the pinching member side. However, there are the following problems.

(Problems to be solved by the invention) In other words, the cutting end of the wire-like material is likely to be held incorrectly by the pinching member, and the chuck length cannot be secured sufficiently, resulting in pinching errors and chuck errors due to the end coming off or spring back. In addition, since the cut end is exposed at the front edge of the outer periphery of the drive pintle, there is a risk that the end may fly off during winding or interfere with the linear object being wound.

(Means for Solving the Problems) In order to solve the above problems, the present invention securely holds the cutting end, stores it in the rotating wheel of the drive pintle, and makes the chuck long enough. This system eliminates chuck errors and enables smooth and quick winding of empty bobbins.Specifically, the system uses a drive for holding and rotating the bobbin as well as a driven pintle for winding the empty bobbin. Sequentially feeds to opposite winding positions,
A fixed amount of wire material is wound onto the bobbin via a traverser, and when the winding is full, a wire material clamp and cutting cutter that can be opened and closed are used, and the wire material passing between the fully wound bobbin and the traverser is pushed out to the clamp and cutter side. In a wire winding device that cuts through a push-out member, a chucking member that grips the cut end that is cut by the cutter and continues to the traverser side, and pulls it below the empty bobbin that has been replaced in the winding position. is provided to be movable up and down, and an extrusion member for bringing a linear object between the chucking member and the traverser close to the bobbin flange side.

(Function) According to the technical means of the present invention, as shown in Figs. A linear object W is placed on the empty bobbin 4 at the winding position.

Although not shown, the empty bobbins 4 are stored in parallel on an inclined chute installed on the right side of the chain conveyor 43, transferred one by one onto the chain conveyor 43, and as the conveyor 43 rotates, the empty bobbins 4 are The fully wound bobbin 4, which is sequentially set in the occupied winding position, is automatically carried out of the apparatus from the illustrated winding position, as is known, and transferred to a stockyard or the like. As is known, the traverser 3 holds a sheave on a screw shaft 6 which can be rotated in the forward and reverse directions by a drive motor 5 so that the traverser 3 can freely move forward and backward in the axial direction parallel to the axis of the empty bobbin 4. The frame is mounted to move forward and backward, and the linear object W is wound around the circumference of the body of the bobbin 4 from one side to the other side, and from the other side to the other side, through the rotation of the bobbin 4. be. As shown in FIG. 3, a known driving pintle 23 and a driven pintle 18 are installed concentrically and opposite each other to grip and rotate the bobbin 4. The shaft end of the drive shaft 8 is rotatably provided through the drive shaft 9, and a rotary wheel 22 is attached to the shaft end, and the shaft end is rotatably provided on the drive shaft 9 through key fitting or the like so that it can move forward and backward in the axial direction. is provided with a drive plate 7 and a shaft support 24 for the bobbin;

Further, the driven pintle 18 is provided with a sleeve 28 in which a shaft 27 having a shaft support 26 of a bobbin is rotatably fitted therein so that the sleeve 28 can move forward and backward in the axial direction. At an intermediate position between the bobbin 4 at the winding position and the traverser, a known linear object clamp 13 and a cutting cutter 14 are provided, as seen in the prior art illustrated above.
Only the installation positions of the clamp 13 and the cutter 14 are shown, and the structure thereof is omitted. The linear object clamp 1

The above is a known structure seen in the prior art, although there are some structural differences, but in the present invention, in such an automatic winding device for a linear material W, the structure shown in FIGS. Thus, the chucking member 16 and the pushing member 19 are newly provided. That is, the chucking member 16 is clamped by the linear object clamp 13 described above, is cut by the cutting cutter 14 in front of it, and is for gripping the cutting end side continuing to the traverser 3 side. 16 is held by a slide holder 36 connected to a piston rod 35 of an elevating cylinder 34 fixed to a frame 33 pivotally supported by a pin shaft 32, and the holder 3

The retraction cylinder 17 is connected to the bar 38 that connects the lower end of the
By pivotally connecting the piston rods 39 and providing the retraction cylinder 17 below the chain conveyor 43, the chucking member 16 can be moved from the raised position shown by the solid line to the position shown by the chain line as shown in FIG. By lowering the cylinder 34 and then retracting the piston rod 39 of the retraction cylinder 17 from this lowered position, the chucking member 16 is retracted directly below the bobbin as shown in the first figure, and the linear object W The gripping position of the end of the chuck by the chuck member 16 is from A to B in the figure, and thereby the chuck length can be sufficiently long. Furthermore, in this invention, the second
As shown in the figure, above the drive pintle 23, a push roller 19 is used as a pushing member for bringing the linear object W extending between the chucking member 16 and the traverser 3 closer to the bobbin flange, and a push roller 19 is connected to the frame 40 and the advancing/retreating cylinder 41. By providing the shaft so as to be able to move forward and backward, the wire material cutting end on the chuck side of the bobbin can be housed within the rotating wheel 22 of the drive pintle 23. That is, the wire material W is wound onto the empty bobbin 4 via the traverser 3, the full winding state is detected by the measuring device 2, and the traverser 3 is moved to the tracking position A shown in FIGS. 2 and 3. After the winding operation is stopped, push rollers 12 and 1 are moved to

and the chucking member 16, and the cutting cutter 14 cuts the wire while the clamp 13 and the chucking member 16 grip the wire. After cutting, the fully wound bobbin 4 is positioned on the chain conveyor 43 by advancing the driving pintle 23 and retracting the driven pintle 18, and also moves the push rollers 12, 12 backward, drives the chain conveyor 43, and places the fully wound bobbin 4 on the chain conveyor 43. 4 is discharged from the conveyor 43, and a new empty bobbin 15 is moved to the winding position, and the drive pintle 23, which was advanced at this time, is moved back and released from the fully wound bobbin. After moving the new bobbin 15 to the winding position, the driving pintle 23 and the driven pintle 18 are first advanced, and after setting the bobbin 15 to the primary mounting position, the chucking member 16 holding the cutting end is moved to the guide bar. 37, 37, and further pulled in by the retraction cylinder 17, the frame 33 is rotated about the pin shaft 32, the lifting cylinder 34, and the frame 3.
6. The guide bar 37 and the bar 38 are all rotated together, and the chuck member 16 is retracted to a position directly below the bobbin 15, so that a sufficient chuck length is obtained. Next, clamp 1 for preventing chuck mistakes.
After closing and gripping the linear object W, the linear object clamp 13 is released. At this time, the bobbin 15 can be rotated without the need to move the retracting cylinder 17 in space, so the wire object W remains vertical and there is no chance of the end of the wire object coming off the clamp or chugging due to spring back, etc. Then, by moving the driven pintle 18 forward secondarily and retracting the driving pintle 23, the end of the wire material is chucked to the bobbin 15, and the clamp 1 for preventing chucking mistakes is opened. At the same time, the push roller 19 is advanced as shown in the second figure, the traverser 3 is started with the rotation of the bobbin 15, and winding of the wire material W onto the bobbin 15 is started with the rotation of the pintles 23 and 18 of the bobbin 15. By bringing the linear object W close to the bobbin flange using the push roller 19, the frictional resistance between the linear object W and the bobbin flange is increased, and the bobbin 15 is wound by rotation. After the winding is started, the push roller 19 is moved backward, and the chucking member 16 is moved forward toward the side opposite to the bobbin, and then raised to the old position.

That is, due to the presence of the chucking member 16 and push roller 19 of the present invention, a chuck length that is approximately 1/2 of the diameter of the winding bobbin can be obtained, and when chucking, the distance between the winding bobbin and the drive plate 7 of the drive pintle is approximately equal to that of the winding bobbin. Even if the length is doubled, a reliable chuck can be obtained without causing chuck defects, and the end of the wire material is stored in the rotating wheel 23, preventing the wire end from scattering during winding. There is no interference with the winding wire material, and as shown in FIG. 4, equipment such as the wire end absorbing roller 20 and guide rollers, which are essential in the case of the conventional technology, is no longer required, and the winding device The overall size can also be made more compact.
