Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of cutting a coil made of a thin sheet-like body into rounds.

Traditionally, aluminum shims, copper, brass, and plastic.

When cutting a coil made of a thin sheet-like material such as paper, the coil is unwound, the sheet-like material is cut into multiple pieces by a slitter, and then the cut sheet-like material is wound up again. Therefore, not only does the process require a considerable amount of time, but the entire surface of the sheet is exposed to air, which causes undesirable problems such as dust adhering to the surface of the sheet. do.

As a countermeasure to this problem, it is possible to cut the coil into rings by rotating the coil and pressing a rotary cutter with an annular blade with an acute-angled cross section against the coiled coil. As the blade is pushed into the coil, there is a problem that the cut end of the coil becomes slanted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coil cutting device that can advantageously solve the above-mentioned problems.

Next, the present invention will be explained in detail using illustrated examples.

1 and 2 show an example of an apparatus for carrying out the method of the present invention, in which both ends of a guide member 50 extending in the left-right direction are fixed to a frame B, and the ends are parallel to the guide member 5. Both ends of the extending moving wire rod 7 are fitted into the frame 6 via bearings so as to be rotatable and immovable in the longitudinal direction of the wire rod, and one end of the wire rod 7 is fixed to the frame B. It is connected to the output shaft of a moving drive device 8 consisting of an electric motor with a speed reducer.

The movable frame 9 is slidably fitted into the guide member 5 and screwed onto the wire rod 7, and the lower end of the cutter support arm 10 is pivoted to the movable frame 9 by a pivot shaft 11 extending in the left-right direction. cutter support arm 10
At the upper end, a central part of a thin disc-shaped double-blade rotary cutter 6 having two annular blades 2 of the same diameter on the periphery and flat both sides is mounted parallel to the pivot axis 11. The cutter support arm 10 is rotatably mounted on a support shaft, and the intermediate portion of the cutter support arm 10 and the movable frame 9 are connected via a cutter pressing air cylinder 12.

The expandable clamp 14 that supports one end of the winding tube 16 of the coil 1 is supported by the upper part of the fixed vertical frame 15 in the frame 6 via a bearing 16 so as to be rotatable and immovable in the axial direction. The expandable flange 17 supporting the other end of the winding tube 16 is rotatably supported by the upper part of the movable vertical frame 18 in the frame B via a bearing 19 so as not to move in the axial direction. The base 20 is provided with a gel insertion slit 21 extending in the left-right direction and a retaining groove 22 for preventing rotation of the bolt head connected to the lower part of the slit 21. The slit 21 and the lower flange 26 of the movable vertical frame 18 The movable vertical frame 18 is attached to the base 2 through the port 24 inserted over the entire length.
It is fixed so that its position can be adjusted in the left and right directions with respect to 0.

A driven sprocket 26 is fixed to a rotating shaft 25 fixed to one flange 14, and the driven sprocket 26 is connected to a driving sprocket 28 fixed to an output shaft of a coil rotation drive device 27 consisting of an electric motor with a reduction gear. A transmission chain 29 is wound around it.

A cutting tape remover 4 made of a scrape having a width equal to or slightly smaller than the thickness of the rotary cutter 6 is arranged at the lower part of the coil 1 in the same left-right phase as the rotary cutter 6. A support rod 60 extending in the radial direction of the coil is provided at the lower end of the cutting tool remover 4.
The upper end portion is fixed, and the support rod 60 is slidably but unrotatably fitted into a bracket 61 that is integrally connected to the movable frame 9, and the upper end portion of the bracket 61 and the support rod 60 What is the air cylinder 62 for pressing the remover?
A plurality of brackets 36 are connected to the fixed vertical frame 15 and the movable vertical frame 18, which are connected via a
are fixed at intervals in the front and back direction, and a support roller 34 is attached to the bracket filter 3 to prevent the coil from falling when the coil cutting is completed. When cutting the coil, The cutter pressing air cylinder 12 is shortened to place the rotary cutter in the retracted position, and the removal tool pressing air cylinder 32 is shortened to place the cutting tape removal tool 4 in the lowered position.
By gripping both ends of the winding tube 13 by the flanges 14.17 and rotating the wire rod 7 by operating the moving drive device 8, the movable frame 9 is moved to an appropriate position in the left and right direction and rotated. The cutter 6 and the cutting tape remover 4 are placed at the position where the coil 1 is to be cut.

Next, the coil rotation driving device 27 is operated to rotate the coil 1, and compressed air for stretching is supplied to each air cylinder 12. 1 and cut the sheet-shaped body constituting the coil 1 sequentially from the outside of the coil to the center of the coil with each blade 2 of the rotary cutter roller, and cut the narrow width produced by the cutting by each blade 2. The tape-like body is scraped off and removed by the cutting tape removal tool 4.

FIG. 1 shows the coil being cut into rings, and FIG. 6 shows an enlarged view of a portion of the coil and rotary cutter in FIG. 1.

When carrying out this invention, a metal spring or any other arbitrary means may be used instead of the air cylinder as a means for pressing the rotary cutter and the cutting tape remover against the coil. Any structure may be used. Moreover, as the cutting tape removing tool 4,
As shown in Figure 4, suction? The lower part of the Tux 55 is connected to a suction source such as a vacuum pump via the suction pipe 36, and the suction pipe 37 is connected to the upper end of the suction box 65, and the cutting tape is removed from the suction pipe 57 by negative pressure suction force. It may be sucked and accommodated in the suction box 65.

An air jet nozzle may also be used to blow away the cut tenips.

According to this invention, the coil made of a thin sheet-like material is rotated without unwinding, and the disc-shaped double-blade rotary cutter 6 having two annular blades 2 on the periphery is produced by rotating the coil without unwinding the coil. By pressing around the coil 1 and rotating it, the sheet-like bodies that make up the coil are sequentially cut from the coil surface side toward the coil center, and the thin tape-like body produced by the cutting is removed by the cutting tape. Since the tool 4 sequentially removes the sheet-like material forming the coil 1, it is possible to cut the sheet-like material forming the coil 1 without exposing it to the air.Therefore, the time required for the cutting process is shortened, and the sheet-like material forming the coil It is possible to prevent dust from adhering to the surface of the rotary cutter 6, and since the rotary cutter 6 is disc-shaped and its both sides do not protrude laterally than the annular blade 2, the cut of the coil 1 can be prevented. The effect of being able to slice the coil perpendicularly to the axis of the coil is obtained.
