Description

The present invention relates to a skein processing apparatus.

(Prior Art and Problems to be Solved by the Invention) The lead wires of electric coils such as solenoid coils and relay coils are usually skeined, that is, multiplexed, and twist). Such procedures are often performed manually, and are therefore time consuming, labor intensive, unreliable and costly. Furthermore, in such a process, the coil winding operation must be stopped when the lead wire is being squeezed,
Work efficiency is also reduced.

Automatic and semi-automatic skein processing equipment has already been used, as disclosed in GB 2049748A. The present invention relates to an improvement of such an automatic skein processing device.

The device described in GB 2049748A carries a retaining ring arranged adjacent to and spaced apart from the passage of the wire formed through the device, and a small ring-shaped wire guide. A shuttle member; and a moving means for multiplexing the wire by moving a wire guide around a closed loop passage surrounding the holding member to hold the wire on the holding member, the moving means for moving the wire formed through the apparatus. Drive means for reciprocating the shuttle member along a straight path substantially parallel to the path and reciprocating the wire guide laterally from the path of the wire to follow a closed loop; the apparatus is further multiplexed. Means for rotating a rotatable holding member, one of the holding members, to twist the wire, the rotatable holding means being in the form of a hook. . The device also includes a positioning motor that returns the hook to the correct orientation at the end of rotation, a means for releasing the skein from the holding member, and a simultaneous rotation and stop of the driving means when the shuttle is released from the multiplexed wire. Control means having a proximity switch for starting rotation of the free holding member. The shuttle has a guide 2 (see FIGS. 1 and 2 of the GB patent) through which the wire is threaded, ie pulls the wire when no operation is being performed. Actually, Guide 2
The tortuous path through the wire tends to adversely affect the outer surface of the wire, causing a sudden reverse turn as it passes through the wire guide 2, causing distortion. Ideally, it should pass through the guide 2 without friction with the guide 2 whenever the skein operation is not performed. It has already been proposed to arrange the guide 2 in such a way that the desired effect is achieved by turning the guide 2 90 ° and feeding it straight. In such a case, another drive component is required, and an appropriate control, that is, a synchronization mechanism is also required.

The present invention has been made to solve the above-mentioned problems of the prior art.

(Means for Solving the Problems) According to the present invention, there is provided a skein processing apparatus for solving the above-mentioned problems of the prior art. This skein processing equipment

A fixed (entrance) guide defining an opening for the wire to be provided, the inner surface of said opening being defined such that during multiplexing the wire can be held and guided around the fixed hook and the twister hook. The configuration is characterized by being performed.

More specifically, the skein processing device of the present invention includes a holding member disposed adjacent to a wire passage defined through the skein device and spaced apart from each other along the passage. A shuttle member carrying the wire guide, and a wire guide adapted to move the wire guide around a closed loop passage surrounding the holding member for holding the wire on the holding member and multiplexing the wire, and Moving means comprising means for reciprocating the shuttle member along a substantially parallel straight path and reciprocating the wire guide laterally from the path of the wire so as to follow the closed loop path;
Means for rotating a rotatable holding member in the form of a hook which is one of the holding members to twist the multiplexed wire, a positioning motor for correctly orienting the hook at the end of the rotation, and releasing the skein from the holding member And a control means comprising a proximity switch for stopping the driving means when the shuttle is released from the multiplexed wire and simultaneously activating the rotation of the rotatable holding member, and comprising an opening. The wire guide is arranged to allow the continuous straight passage of the wire when the shuttle is stationary, the inner surface of the opening holds the wire around the fixed hook and the twister hook during multiplexing and A configuration characterized by being defined so as to be able to be guided can be adopted.

Hereinafter, the present invention will be described with reference to examples shown in the accompanying drawings.

FIG. 1 shows an embodiment of a skein processing apparatus according to the present invention. The skein processing apparatus of the present embodiment includes a wire supply motor 10 and a chain (not shown in FIG. 1) drive. Drive motor 11 for motor and tachometer (tachom
eter) 12 and a rotatable twister needle (twisternee)
dle) 13 (first holding member), and a fixed hook 14 attached to a plunger of a solenoid 15 carried on a carriage 16.
(Second holding member). The needle 13 is driven by a motor 17 during use,
The rotation of the needle is monitored by a counter 18 for relative position and number of rotations. A carriage drive motor 18A monitored by the tachometer 19 is provided to move the carriage 16 with respect to the needle 13 as necessary. A flyer 20 is located adjacent the input for introducing the wire into the skein processing device, the flyer having two working positions. In addition, wire gauge monitor 21
And a wire tensioner 23. A microcomputer 22 is programmed to control and monitor the operation of the skein processing device.

As shown in FIG. 2, a shuttle 23A is provided, and is driven by a chain 24 driven by the motor 11 of FIG. A shuttle such that a fixed circular guide 25, also shown in cross section, passes a wire 26 between a fixed circular inlet guide 27, also shown in cross section, and the axis of rotation of the rotatable twister needle 13. It is attached to 23A. Chain 24 and shuttle 23A
When the multiplexing is not performed, the wire is stationary and the wire is supplied to a coil winding device (not shown) arranged on the left side of the needle 13 via the skein processing device.

The guide 25 is arranged so that the wire 26 can continuously pass through the guide 25 with little or no contact with the inner surface of the guide 25.

In FIG. 3, the shuttle 23A is connected to the wire 26 with the fixed hook 1
The first turn of the multiplexing sequence has been started so that 4 is wound around. Shuttle 23A
Is moving toward the rotatable needle 13. When the shuttle 23A is in the leftmost position as shown in FIG. 4, the wire 26 is hooked to the needle 13 before the shuttle 23A returns to the fixed hook 14. Wire
26 engages the fixed hook 14 in this position on the same side as the first turn. However, in practice, when the shuttle 23A moves to the right, the wire 26 is pulled below the fixed hook 14 before the shuttle 23A makes the next turn to the fixed hook 14. Such an operation can be easily performed. This is because the fixed hooks 14 are arranged several degrees with respect to the vertical direction, that is, at an angle upward from the plane of FIG. Fix the wire 26 stretched between the hooks 14
Because it is easier to release under the By arranging the needles at an angle to the vertical in this way, when the shuttle moves counterclockwise around the needles during the multiplexing operation,
The winding of the wire 26 around the needle 13 can be improved.

When multiplexing is complete, the needle 13 is rotated in a normal manner to form a skein, and then the locking hook 14 is retracted and directed in a normal manner through the hollow center of the needle 13 to the front passage. Release the skein. A more detailed description of the device is given in UK Patent Application No. 8716317.

FIG. 5 shows, in cross-section, a guide 50 which is an alternative to the guide 25 of FIGS. 2 and 4, which comprises an extension or leg 5 for securing the guide to the shuttle 23A.
1 is provided. The top of the guide 50 forms a loop extending up and down the hook of the twister needle 13, and
It must be dimensioned to pass below the level of the stripper plate 14A at the base of the fixed hook 14. The bottom of the guide 50 must be positioned so that the wires can pass freely or continuously for through-feeding when multiplexing is not taking place. Despite these restrictions, the shape and size of the fixed guide 50 suitable for use can be selected over a wide range. However, constructional constraints that the wire must always hold under the bottom edge of the fixed hook 14 to return the shuttle from the position shown in FIG. Without it, it was not possible to perform a reliable operation of the shuttle guide, which had to be pivotable between the feed position and the multiplex position. The present invention can provide a significantly improved skein processing apparatus by eliminating such a restriction on the configuration, and can sufficiently provide a fixed shuttle guide having a usable configuration. Thus, the guide can provide a reliable multiplexing guide suitable for continuous threading, without damaging or straining the wire during threading when no skein operation is being performed. Now you can.

It can be easily seen from FIG. 2 that there is a straight line extending through the guides 25 and 27 to the axis of the needle 13. This allows for a straight wire threader
threader) can be supplied via a skein processor at the start of the operation. Thus, the first threading of the wire 26, which is often very fine in gauge gauge of the wire, and which is particularly difficult to pass through tortuous passages, can be significantly facilitated.

(Effects) As described above, the skein processing apparatus of the present invention can perform continuous feed supply without causing damage or tension to the wire during feed supply when the skein operation is not performed. , The wire gauge is extremely fine,
Moreover, even if the passage is tortuous, the initial threading of the wire can be performed very easily.
