Description

[Detailed description of the invention] Winding machine with wire hook folding member for tapping Technical fields related to the invention・ The present invention relates to a winding machine for winding closed, generally annular cores, the winding machine comprising: supporting and advancing a wound core rotatably about its own axis on a first surface; a guide and drive device, a dowel-shaped wire guide device, and a winding perpendicular to the first surface; The wire guide device is rotated within the plane and the movement path of the wire guide device is set to the cross section of the core. It includes a control and drive system that covers the

For example, in the winding of an annular core used in transformers, it is usually wound around this core. It is necessary to provide one or more tappings from one or more partial windings. like this Tapping is often done not only at both ends of a continuous winding, but also at the center, for example. Place it at one point in the center of the winding, such as when making a winding with a 3-inch wire.

When using a conventional percentage line machine of the relevant type, a large number of steps are required to perform tapping. When winding successive windings, stop the winding operation, pull out the loop of wire to be wound, And it is necessary to fix this. Moreover, it essentially prolongs the winding process, The need for such manual labor poses considerable obstacles to the automation of this type of winding work. 5. The purpose of this invention is to eliminate the above-mentioned problems and stop tapping and winding work. optionally on one winding by selective action or automatic programmed action without 2 Special Table of Contents 59-50 (193G(2)) This purpose is This is achieved through the design of this type of winding machine, which uses hook-shaped wire hooks. A folding machine is disposed so as to be pivotable about an axis parallel to the winding surface, thereby generating a first bias. When resisting a force and receiving an actuating force, the grip is moved from the rest position outside the winding surface to the inside of the winding surface. Make a pivoting motion to the hooked position to grasp one wire loop, and tension this loop. the wire hooking member acts in the opposite direction and is less than the first biasing force. Between the body IL position and the hooked position or the outer side of the winding surface, the The wire hook folding member is moved to the holding position, and the wire hook folding member is moved to the holding position. , generates an actuating force that is controlled to maintain said force during a specified folding time. It is characterized by having a member that

The invention provides a type of wire scheme which is loaded by the winding wire prior to the winding operation. Using an internal device or using a wire magazine to move the magazine in one direction and the other. During rotation, take out from the bottom exit [] slit and supply from the inlet slit at the same time. Either way, it can be used with any type of winder of the type described above.

This invention is applied to a so-called single ring machine, in which a wire guide The machine consists of only one wire magazine, similar to a so-called double-ring machine. In this multi-ring machine, the wire guide device consists of individually driven wire advancing rings. The wire travels coaxially with the ring and rotates in the same direction as the ring, but its rotation is independent. Includes a standing wire magazine.

However, the advantage of this invention regarding the high level of automation is that it does not require much manual effort. In addition, winding machines that perform other types of winding operations with a high degree of automation, such as international Patent Application No. PC'I'/DK8010 OO58, International Publication No. W○811008 This is particularly evident in winding machines of the type described in No. 41.

In the wire magazine 1, the wire to be wound is supplied through the bottom slit 4 shown in FIG. away from the axis of rotation in the same working cycle as taking out the wire to wind the core. This is done through the filling slit (not shown) located at 1ill of the wire magazine facing the side. be exposed. This wire magazine 1 has International Patent Application No. PCT/DK80100057 It is similar to the type described in International Publication No. WO31100840.

As shown, the object to be rolled is arranged, for example, in a support device 6, which is shown only schematically. It consists of an annular iron core 5 placed in the winding process. The magazine 1 rotates within a plane 7 perpendicular to the winding plane determined by 8. It will be implemented to ensure that

The cassette 2 is opened and opened so as to position the core 5 in the same way as the wire magazine 1. Therefore, its cross section is surrounded by the movement path of the magazine 1 within the winding surface 8.

During one rotation of the wire magazine 1, the winding wire 9, which has also been pulled out from the bottom slit 4, is It is guided around the inside of the winding surface 8. In Figure 1, 9(Z, 91!l and σ9C are , showing three different positions of the winding wire during one revolution. one with a specified number of turns A corresponding number of revolutions must be carried out by the wire magazine IK to provide the winding requirement. Each rotation must perform one turn on the core. At the same time, the wire The magazine has a wire 5 that corresponds to the circumference of the magazine. Receive the length of 9. Therefore, for valley rotation, one wire margin is the magazine's are fed into the magazine 1 approximately corresponding to the difference between the circumferential length and the circumference of the cross-section of the core. . Sufficient length of wire for the desired winding was thus fed into the magazine. When the wire 9 is exhausted, the wire supply into the magazine is exhausted and the winding wire is wasted. Continue rotating until the magazine is cut 10 times without stopping.

The bearing block 22 is journal-bearing within it. Between the end portions 17 and 18, The shaft 16 includes a center portion 23, in which the wire hooking member 10 is arranged radially. It is rotatably journal-beared by an aluminum bearing 24.

Close to the axial position of the wire hook folding member 10, the fan-shaped carrier part 25 is biased at @16. Attached to the center portion 23, said carrier member is attached to a portion of its circular outer periphery as shown in FIG. It has a concave part 26 as shown in FIG. 727. The concave portion 26 is defined by radial edges 26a and 26b. are defined at both ends, and these are placed in the working position of the wire hooking member 100 and the carrying bottle is The hook-folding position 10h and the holding position lOc for 27 constitute contact portions of each.

It is prescribed to move the wire hook folding member 10 from the rest position 10α to the hook folding position 1ob. A coupling rod ring formed at the end of the main piston 30 for rotating the shaft 16 through an angle. The journal shaft 29 is further mounted on the eccentric center of the shaft 16 by the radial bearing 28. The piston receives pressure through the inner hole 31 provided in the bracket plate 12ff. It communicates with a thin film 32 that constitutes one wall of the force chamber 13 .

In the non-actuated state, the shaft 16 is provided by a helical spring 33 shown in FIG. The first biasing force causes the wire hooking member 10 to occupy a position corresponding to the rest position. and both ends of the spring 33 are connected to the slit in the upper end portion 17 of the shaft 16 and the upper bearing block. are attached to the collars 34 of the hooks 34, respectively, so that the biasing force is applied as indicated by the arrow 35. Acts in the direction shown.

When compressed air is supplied to the pressure chamber 13, the thin film 32 is deformed and the main histostone 30 is actuated so that the membrane, along with the bonding Ron link 29, is axially symmetrical about axis 16. The plane passing through the axes of the end portions 16 and 17 and the eccentric center portion 23 is the plate plate. From the rest position indicated by the line '#: in FIG. The surface is moved to the position shown by the dashed line, which is approximately perpendicular to the plate bracket 12. this movement , the shaft 16 is rotated approximately 90° against a first biasing force indicated by arrow 35.
