Embodiment FIG. 1 is a plan view illustrating a specific example of the device of the present invention, and FIG. 2 is a longitudinal cross-sectional view taken along - in FIG. 1. Base 1 as seen in these drawings
1, a cylindrical cam 13 is provided with cam grooves 12a, 12a formed therein over a limited area along the circumferential direction of the outer peripheral wall surface by suitable fixing means such as screws.
is fixed. There is a ring-shaped guide rail 14 around the cylindrical cam 13, on which a cylindrical cutter holder 15 is rotatably arranged. In the illustrated embodiment, a handle 16 is fixed to the side wall surface of the cutter holder 15 to constitute a device for rotating the cutter holder 15 by manual operation. It is also possible to use a combined drive device (not shown) to provide an automatic cutting device that automatically rotates the cutter holder 15. A pin 17 is installed on the upper end surface of the cutter holder 15,
A support member 20 is attached. This pin 17
The cam follower 18a, 18b and the support member 20 of the cutter 19 are swingably attached to the cam follower 18a and 18b, which swing around the cam follower 18a and 18b, and the support member 20 of the cutter 19. Specifically, as shown in FIG. 4, the cam follower 18 and the cutter 19 are supported in a swingable manner by a spring member 24 of an elastic spring for elastically contacting the cam follower 18 with the cam groove on the pin 17 implanted in the holder 15.
The stopper 23 of this and the support member 20 to which the cutter 19 is attached are assembled. Further, a shaft member 21 is implanted in the support member 20, and rotatably holds the cam follower 18. On the other hand, on the upper surface of the support member 20, a shaft member 21 is implanted and fixed at an appropriate distance from the pin 17, and functions as a support member for the cam follower 18 and the cutter 19. The cam follower 18 is rotatably fitted into the shaft member 21, and engages with cam grooves 12a, 12a formed along the circumferential direction of the outer wall surface of the cylindrical cam 13 when the cutter holder 15 rotates, thereby causing the shaft A cutter 19 fixed to the upper end of the shaped member 21
a, 19b are caused to swing forward and backward in the diametrical direction of the cam. Cam follower 18a,
In order to reliably press the cam followers 18b against the cam grooves 12a, 12b, the cam followers 18a, 18b are always pressed against the cam grooves 12a, 12b by a spring member (see FIG. 4) of a pressure spring attached to the support member 20.
It is biased in the direction of pushing into 12b. As illustrated in FIG. 1, four sets of cutter devices are attached to the upper end of the cutter holder 15 at predetermined pitches,
Correspondingly, four cam grooves 12a, 12 are formed on the outer circumferential wall surface of the cylindrical cam 13, and the engagement surfaces with the cam followers 18a, 18b, 18c, 18d have different heights.
b, 12c, and 12d are formed. Therefore, when the cutter holder 15 rotates, the first cam follower 18a engages only with the corresponding first cam groove 12a, and the first cam follower 18a paired with the first cam follower 18a
A rocking motion is caused only in the cutter 19a in the radial direction of the cam. Similarly, the second to fourth cam followers 18b, 18c, 18d and the second to fourth cam grooves 12b, 12c, 12d are engaged with each other, and the corresponding cutters 19 are individually moved forward and backward. This causes a rocking motion. In this way, a rotation path of the cutter holder 15 is formed in which a specific cam follower, for example, the first cam follower 18a, does not engage with any of the cam grooves 12b, 12c, and 12d other than the first cam groove 12a with which it is paired. Ru. Cam grooves 12a, 12b, 12c, 12d
The disposed phase difference between the cutters 19a, 19b, 19 is such that the synthetic resin tape 22, which is disposed and supported around the cutter holder 15 in a concentric manner with the cutter holder,
c and 19d, adjust the length of the cutter's movement so that the cut is made on the same plane without leaving any cut ends.
They are selected to form an overlap area of approximately 10°. FIGS. 2a and 2b show the state in which the tape 22 is stretched by lowering the tensioning support 31, and the lowering operation is performed by rotating the disk 32 by motor vibration and lowering the tensioning support using a crank mechanism. There is. Here, as shown in FIG. 2b, the cut portion of the synthetic resin tape 22 is cut by placing the wafer vertically on the side of the cylindrical ring 30 that holds the attached tape 22, and within the range of the swinging motion of the cutter 19. There is a tension support 31 located inside and extending downward, and below the cutting position. Note that, prior to cutting, the tensioning support 31 is used to tension the tape, as shown in FIG. 2a, and fixes the tape 22 to the cylindrical ring 30 in the tape tensioned state. That is, the cylindrical cam 13
A driving means for vertically moving the tensioning support 31 is provided below the base 11 that supports the guide rail 14, and the tape 22 is placed at a predetermined position on the side wall side of the cylindrical ring 30 by rotation of the motor. Since the device of the present invention is constructed as described above, the handle 16
cam groove 12 by rotating the cutter holder 15 approximately 100 degrees forward around the cylindrical cam 13.
The cam follower moves from the bottom toward the surface of the cylindrical cam 13, and along with this, the cutter advances to the cutting position and cuts the tape 22. After the cutting operation is completed, the cutter holder 15 is reversely rotated by approximately 100 degrees, so that the cam follower 18 is moved back toward the cam center to a position where it engages with each corresponding cam groove 12, and enters a standby state. The cutting cycle is then completed by loosening the illustrated tension support 31 and removing the tape 22 from the cutting device.

Effects of the invention The above-mentioned cutting device for tape-shaped materials can be used to semi-automatically or automatically cut tape-shaped materials, which previously had to be done by hand, thereby improving the precision of cutting dimensions. It can be done safely. According to the present invention, the cutter performs cutting operations while maintaining an accurate relative operating position for the tape-shaped material that is stretched and supported, so there are no accidents such as cutting errors that would otherwise occur if manual work was used. At the same time, the index also improves. Furthermore, after the cutting operation is completed, the cutter returns to the standby position where there is no risk of damaging the tape-like material by retreating into the cam groove of the cam follower, which greatly improves operability compared to the conventional technology. It can produce a spinning effect.
