Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter for exfoliating a bobbin wound layer wound with a yarn or a film.

[0002]

2. Description of the Related Art In a fiber production process, a package (bobbin wound layer body) in which a yarn is wound around a bobbin is shipped after a strict quality inspection. A package that fails this quality inspection is designed to be stripped from its bobbin as a waste thread. Conventionally, an operator manually cuts off a defective package by using a cutter, but since it is a very complicated operation, a considerable amount of time is required for the exfoliation processing per package. In short, it was a cause of lowering productivity.

The exfoliation treatment of such quality rejected products is performed on the bobbin wound layer of the film even in the film production process. However, when the bobbin wound layer body of this film is peeled off, the work is similarly complicated, and it takes a considerable amount of time to peel off the bobbin layer body, which causes a decrease in productivity.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a peeling-off cutter capable of easily peeling off a bobbin wound layer body whose quality has failed as described above.

A cutter for exfoliation treatment according to the present invention, which achieves the above object, has a rotary blade driven by a drive source mounted on a housing, and compressed air is provided around the rotary blade toward the rotary blade. It is characterized by arranging a nozzle for ejecting. By arranging the compressed air jet nozzle around the rotary blade in this way, the rotary blade during cutting the bobbin wound layer body is cooled by the compressed air, and the temperature rise due to frictional heat is suppressed, so efficient cutting is performed. to enable.

Further, when a nozzle for injecting compressed air toward the bobbin wound layer body is installed at a position in front of or behind the rotary blade, the cut end of the bobbin wound layer body is cut by the rotary blade. Since the compressed air is sprayed to widen the cut end, the exfoliation process can be performed more efficiently.

[0007]

The present invention will be described in detail below with reference to the embodiments shown in the drawings. 1 to 3 show a stripping cutter according to an embodiment of the present invention. As shown in these figures,
The bobbin wound layer peeling-off cutter 11 is configured by incorporating a rotary blade 11a in a housing 21 such that the blade tip projects from the lower surface. The housing 21 is formed into a boat shape as a whole and is divided into left and right blocks 21a,
21b. A rotary shaft 22 is rotatably supported by one block 21a, and a pulley 23 is fixed to a shaft end projecting to the outside thereof, and power is input from a drive source via a belt 18 wound around this. . The drive source is provided with a motor 13 as shown in FIG. 4, for example.

The inner end of the rotary shaft 22 pivotally supported by the block 21a faces a space portion 24 formed in the mating portion with the block 21b, and the rotary blade 11a is fixed thereto.
The rotary blade 11a has a blade tip protruding below the housing 21, and the lower surface of the housing from which the blade tip protrudes is
It is formed in a concave cylindrical shape so as to cover the upper surface of the winding layer Pm of the package P (see FIG. 2).

Further, the nozzle 2 is provided at the upper position of the space 24 in the mating portion where the two blocks 21a and 21b are in close contact with each other.

FIG. 4 shows an example of an exfoliation treatment apparatus equipped with the above-mentioned exfoliation treatment cutter of the present invention. The device for attaching the cutter is not necessarily limited to the embodiment shown in FIG. In FIG. 4, P is a bun type package (bobbin wound layer body) to be exfoliated by the cutter of the present invention. As a result of the quality inspection, this package P is determined to be defective in the yarn of the winding layer Pm wound on the bobbin 20.

Reference numeral 1 denotes a box-shaped support base made of a frame material, which can be moved to any place by a caster 2. A fixed plug 3 and a movable plug 4 are installed on the support base 1 so as to sandwich both ends of the bobbin 20 of the package P, and the movable plug 4 has an actuator 5
It is designed to reciprocate in the axial direction. The package P is fixed by inserting one end of the bobbin 20 into the fixed plug 3 and inserting the moving plug 4 into the other end.

Further, the bobbin 20 is provided below the moving plug 4.
The pedestal 6 that supports the end of the above from the lower surface is provided, and the pedestal 6 can also be moved in the axial direction independently of the moving plug 4 by the actuator 7. When the package P is fixed by the fixed plug 3 and the movable plug 4, the pedestal 6 supports the bobbin end portion in advance, and then the movable plug 4 is moved and fixed. Further, the pedestal 6 can be moved according to the size of the package P, as shown by the chain line in the figure, and can be adapted to any size regardless of the size of the package P.

An actuator mechanism 8 is provided on the lateral side of the package P supported by the plugs 3, 4 and the like as described above. The actuator mechanism 8 is composed of a first actuator 8a and a second actuator 8b. The first actuator 8a reciprocates the second actuator 8b in the X direction (axial direction of the package P), and the second actuator 8b moves the support plate 12 provided with the above-described cutter 11 of the present invention in the Y direction (package. It is adapted to reciprocate in the radial direction of P).

The actuating mechanism of the first actuator 8a may be any mechanism as long as it makes a linear reciprocating motion. For example, it is possible to use one in which a lead screw 9 that is reciprocally rotated by the synchronous motor 10 is screwed to the base of the second actuator 8b, and the second actuator 8b can be reciprocally moved by reciprocally rotating the lead screw 9. . The second actuator 8b can also reciprocate the support plate 12 by the same mechanism.

The rotary blade 11a of the cutter 11 on the support plate 12 is driven by a motor 13 via a belt 18. When the actuator mechanism 8 equipped with the cutter 11 is actuated in the X direction by the first actuator 8a, the rotary blade 11a of the cutter 11 axially cuts the surface of the winding layer Pm of the package P, and the actuator mechanism 8 reciprocates. When the second actuator 8b moves in the Y direction (radial direction of the winding layer Pm) every time it moves, the cutter 11 is pushed down to cut the winding layer Pm in the depth direction.

A waste box 14 is installed below the package P, which is cut in this way, so as to accommodate the thread waste that falls from above. The waste receiving box 14 can be taken in and out of the support base 1, and when a predetermined amount of waste yarn is accumulated, it can be replaced with an empty waste receiving box 14. Further, the above-mentioned exfoliation processing device is provided with a starter switch 15, an emergency stop switch 16, a control panel 17, and the like. The starter switch 15 is a push button that activates the exfoliation processing device, and the emergency stop switch 16 stops the exfoliation processing device when an emergency occurs during the exfoliation work.

The control board 17 has a built-in circuit for controlling the automatic exfoliation processing work, and inputs the size of the package P and the like to operate the actuators 5, 7, the first actuator 8a, the second actuator 8b and the like. The quantity is set, and the winding layer Pm of the package P is set by these operations.
The exfoliation process is automatically performed. Further, a weighing unit (not shown) is installed on the bottom surface of the waste receiving box 14, and when the amount of waste in the waste receiving box 14 reaches a predetermined weight, the weighing unit detects it and performs the peeling process of the cutter 11. The work is automatically stopped, and an alarm unit such as a lamp or a buzzer is used to notify.

The package P is produced by the above-mentioned exfoliation treatment device.
When the automatic stripping process of the winding layer Pm is performed, the stripping process time per package is 20 to 30 seconds, and it can be shortened to a fraction of 1 to tens of minutes as compared with the conventional manual work. Therefore, the productivity can be remarkably improved. The above-described stripping cutter of the present invention can be applied not only to the yarn package as described in the embodiments but also to a bobbin wound layer wound with a film. Further, in the case of the yarn package, the form is not limited to the case of the bun, but can be applied to the case of a drum type or cheese winding. Further, the type of yarn is not limited to synthetic fiber, and can be applied to natural fiber.

[0021]

As described above, in the bobbin wound layer peeling-off cutter according to the present invention, the rotary blade is cutting the bobbin wound layer body by disposing the compressed air jet nozzle around the rotary blade. Since it is actively cooled by compressed air, temperature rise due to frictional heat is suppressed and efficient cutting is possible.

Further, when a nozzle for injecting compressed air toward the bobbin wound layer body is installed at a position in front of or behind the rotary blade, the compressed air is applied to the cut end of the bobbin wound layer body after cutting with the rotary blade. Since the cut is widened by spraying, the exfoliation process can be made more efficient.
