Description

[Detailed Description of the Invention] This invention relates to an improvement of an assembly device for a wound article such as a wound core.

Hereinafter, a wound core assembly apparatus will be explained as an example. Conventionally, there have been apparatuses of this type as shown in FIGS. 1 and 2.

Fig. 1 shows the plane of this device, and Fig. 2 shows the plane II-- of Fig. 1.
This figure shows a cross section taken along line II. In the figure, 1 is a cylindrical winding frame, 2 is a support shaft that rotatably supports this winding frame 1, and 3 is a moving body that supports this support shaft 2. stand 3
is guided by the guide shaft 4 and moves in the left-right direction together with the support shaft 2.

5 is a plywood board to which the guide shaft 4 is fixed via a support member 6; 7 is a moving body, for example an endless belt; this belt 7 is driven by a drive roller 8 and guided by a guide device, for example a pulley 9; The winding frame 1 is rotated while applying a clamping force to the winding frame 1.

10 is a tension adjustment device for keeping the tension of the belt 7 constant via a tension pulley 11; 12 is a support base for supporting this tension adjustment device 10 and fixing it to the base plate 5; and 13 is a wound body. 14
This is a wound core in which a band-shaped steel plate 13 wound around the winding frame 1 is formed by the clamping force of a belt 7.

In the wound core assembly device configured as described above, when the drive roller 8 rotates in the direction of arrow A in the figure, the condoless belt 7 circulates in the direction of arrow B, and the winding frame 1 is moved in the direction of arrow C. Rotate.

When a plurality of strip steel plates 13 are inserted between the belt 7 and the winding frame 1 which are being driven in this way in the direction of the arrow, the steel strips 13 are wound around the winding frame 1 while being It is formed into a desired shape by the clamping pressure between the frame 1 and the belt 7.

By repeating this operation, a wound core 14 wound to a predetermined lamination thickness is formed.

Next, the belt pressing force of the tension adjustment device 10 is reduced, and after loosening the belt 7 from the wound core 14, the formed wound core 1 is removed.
Remove 4.

Note that as the laminated thickness of the winding core 14 increases, it is necessary to increase the relative distance between the two guide pulleys 9a adjacent to the winding frame 1. Adjustment of the tension of the belt 7 is performed by moving the shaft 2 to the right in the figure by the moving table 3 guided by the guide shaft 4, and the tension of the belt 7 due to the increase in the diameter of the wound core 14 is adjusted by the tension adjustment device 10. This is done by moving the tension pulley 11 to the right.

The conventional wound core assembly device is configured as described above, and the vertical position of the belt is fixed. Therefore, if the material width of the steel strips supplied differs due to the change in the capacity of the wound core, the belt cannot be clamped. The belt that applies pressure pinches the center of the strip steel plate at a position where it has deviated from the center, which upsets the pressure balance in the width direction of the core that is being wound and forms, resulting in a difference in the winding diameter at both ends of the core. However, there was a drawback that a wound core with distortion was formed.

This idea was made to eliminate the above drawbacks.
A belt adjustment device is installed to move the belt that pinches the wound core in the width direction of the wound core, so that it can accommodate wound cores of different widths.
It is an object of the present invention to provide a wound core assembly device in which a wound core without distortion is formed by adjusting the position of the belt to an appropriate position in the core width direction.

An embodiment of this invention will be described below with reference to the drawings.

Figure 3 shows the plane of this invented device, and Figure 4 shows the TV shown in Figure 3.
This figure shows a cross section taken along line -IV.
The same reference numerals as those in the figures and FIG. 2 indicate the same or corresponding parts, so the explanation will be omitted.

Reference numeral 15 designates a plurality of belt position adjustment devices provided on the base plate 5, which includes a belt support 15a that contacts the belt 7, and a belt support 15a that moves the belt support 15a in the width direction of the wound core 14 (vertical direction in FIG. 4). The drive unit 15b is shaped like a ratchet.

Next, the core width of the wound core 14 is W, the belt width is V, and the length of both ends of the wound core that is not pinched by the belt 7 is 11.
, 12. The height of the belt support 15 a from the base plate 5 is assumed to be H, and the operation of adjusting the position of the belt 7 using this device will be explained.

When the tension pulley 11 of the tension adjustment device 10 is moved backward and the tension on the belt 7 is loosened, the belt receiver 15 is moved back.
When the belt a is advanced or shortened up and down by the drive section 15b, the lower end of the belt 7 that comes into contact with the belt receiver 15a is set at the belt love height H position.

At this time, the belt height H is adjusted so that the belt 7 is always set at the center position of the wound cores 14 having different core widths W, that is, 1□=12.

Thereafter, a predetermined clamping force is applied to the belt 7 by the tension adjusting device 10, and the wound core 14 is applied as in the conventional wound core assembly device.
to form.

FIG. 5 shows a plan view of a device according to another embodiment of this invention, and FIG. 6 shows a cross section taken along line VI-VI in FIG. Since the reference numerals indicate the same or corresponding parts, the explanation will be omitted.

Reference numeral 16 denotes a belt position adjustment device that moves the belt 7 portion that goes around the winding frame 1, and a belt holder 16 that comes into contact with the belt 7.
a, a drive section 16b that moves the belt receiver 16a in the width direction of the core, and a drive section 16b that follows the increase in the laminated thickness of the core wound around the winding frame 1. Alternatively, after positioning the belt 7, the elastic part 16 is moved back.
It is composed of C.

If the wound core assembly device is equipped with a belt position adjustment device that arbitrarily moves the belt portion surrounding the winding frame in the core width direction, the belt that pinches the core width center of the wound core can be directly adjusted to the desired position. , which has the effect of improving positional accuracy.

As described above, according to this invention, in an assembly device that inserts and press-forms a wound object to be wound around a winding frame between the winding frame and a movable body, the object to be wound is compressed. A position adjustment device that can move the movable body to any position in the width direction of the object to be wound is provided, so even when the width of the object to be wound is different, the object to be wound can be clamped in a well-balanced manner, and the object to be wound can be wound without distortion. can get things.

Furthermore, if the movable body pinches the center position of the wound object, the pinching force of the movable body will be applied evenly, and the reaction force acting on the movable body as a reaction to this will also be equal, so that only one side will expand. It is possible to prevent uneven deformation of the moving body and extend the life of the moving body.
