Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tape marking device for cutting a tape into a predetermined length and feeding it as a mark.
[0002]
[Prior art]
Conventionally, as one type of tape marking device, for example, as disclosed in Japanese Examined Patent Publication No. 62-9500, a cutting portion for cutting a tape with a fixed cutter and a movable cutter, and a tape wound around a reel are used. The tape feed mechanism that feeds out and the drive unit that incorporates the cutter drive mechanism that drives the movable cutter are connected via a tape guide rod, and the tape fed by the tape feed mechanism is guided and fixed by the tape guide rod. There is a system in which a tape is cut by inserting between a cutter and a movable cutter and operating the movable cutter by a cutter driving mechanism.
[0003]
This type of tape marking device has a small cutting section, an elongated tape guide rod, and the tape reel and drive section, which are limited in size, can be separated from the tape feeding section ahead of the cutting section. There is an advantage that it can be used even if the space around the location is narrow.
[0004]
[Problems to be solved by the invention]
However, in the past, since the cutting part was fixed to the tip of the tape guide rod, in order to change the tape feeding direction ahead of the cutting part (tape insertion angle fed between sheets), the inclination of the entire tape marking device must be changed. Therefore, the installation site was surveyed in advance to determine the angle, and the entire tape marking device was designed to match that angle. For this reason, the specifications must be different for each installation site, which is uneconomical.
[0005]
In the present invention, by making the cutting portion swingable with respect to the tape guide rod, the tape feeding direction (angle) ahead of the cutting portion can be arbitrarily adjusted in the field, and the cutting portion can be adjusted to the tape guide rod. On the other hand, even if the head can be swung freely, the object is to smoothly guide the tape from the tape guide rod into the cutting portion.
[0006]
[Means for Solving the Problems]
The present invention drives a cutting portion that cuts a tape introduced from a tape introduction port of a case with a fixed cutter and a movable cutter in the case, a tape feeding mechanism that sends out the tape wound around a tape reel, and the movable cutter The drive unit with a built-in cutter drive mechanism is connected via a tape guide rod, and the tape fed by the tape feed mechanism is guided by the tape guide rod and inserted between the fixed cutter and the movable cutter. A tape marking device that operates a movable cutter with a cutter driving mechanism to cut a tape has the following configuration.
(A) The cutting portion is attached to the tip of the tape guide rod so as to be able to swing up and down with a swing shaft.
(B) The angle of the cut portion can be arbitrarily adjusted by forming a screw on the swing shaft, screwing a nut into the swing shaft, and tightening the cut portion.
(C) In order to guide the tape from the tape guide rod into the cut portion in the gap between the tip of the tape guide rod and the cut portion, one end of the leaf spring-like tape guide tongue piece is fixed to the case of the cut portion.

However, in this tape marking device, firstly, the cutting portion 2 is attached to the tip of the tape guide rod 7 so as to be able to swing up and down. Secondly, the cutter driving mechanism 5 in the driving unit 6 and the movable cutter in the cutting unit 2 are connected by a flexible shaft 8 in order to cope with the swinging of the cutting unit 2. Third, if the cutting portion 2 can be swung with respect to the tip of the tape guide rod 7, a gap is formed between the tip of the tape guide rod 7 and the cutting portion 2. A tape guide is provided separately from the portion 2.
[0010]
Hereinafter, each structure will be specifically described.
As shown in FIG. 2, the tape guide rod 7 covers the groove 7a over the entire length with a cover plate (band plate) 7b, and guides the tape 1 along the groove 7a.
[0011]
In the cutting part 2, as shown in FIG. 3, in a box-shaped case 11 in which a main body 9 is covered with a cover 10, a rotating frame 12 is pivotally supported by a shaft 13 so as to be vertically rotatable. By slidably fitting the lateral holes 14 on both sides and the pins 16 of the movable cutter 15, the movable cutter 15 can be moved up and down by the rotation of the rotating frame 12, and the fixed cutter 17 is fixed to the main body 9. Has been. As shown in FIG. 4, the fixed cutter 17 has a chevron blade 17a at the upper edge, and the movable cutter 15 has a front gate shape, and the lower edge of the upper side of the gate shape has a chevron blade 15a. The positions of the movable cutter 15 and the fixed cutter 17 are different from each other back and forth. When the movable cutter 15 is in the upper fixed position as shown in FIGS. 3 and 10, the blade 15a of the movable cutter 15 and the fixed cutter 17 The tape 1 can be inserted between the blade 17a, and when the movable cutter 15 is lowered as shown in FIG. 10, the tape 1 is cut.
[0012]
In the box-shaped case 11, upper and lower tape guide plates 18, 19 are opposed to each other at a predetermined interval, and the tape 1 guided by the tape guide bar 7 is sent to the tape guide plate 18. 19 is introduced into the box-shaped case 11, guided between the blade 15 a of the movable cutter 15 and the blade 17 a of the fixed cutter 17, and from a tape discharge port 10 a (FIG. 5) formed on the front surface of the cover 10. Discharged.
[0013]
In order to make the cutting portion 2 swingable with respect to the tip of the tape guide rod 7, as shown in FIGS. 6 and 7, a bearing protrusion having a shaft hole 20a on one side of the rear surface of the main body 9 of the cutting portion 2 is provided. Part 20 is provided. On the other hand, a pair of left and right bearing pieces 21 and 22 are fixed to both side surfaces of the tip portion of the tape guide rod 7 with screws 23. One bearing piece 21 is provided with a circular shaft through hole 21a, and the other bearing piece 22 is provided with an elliptical shaft fixing hole 22a. The swing shaft 24 has an elliptical detent portion 24a, a roller bearing portion 24b, and a main shaft portion 24c having a smaller diameter than the roller bearing portion 24b, and a screw 24d is provided on the main shaft portion 24c. As shown in FIGS. 8 and 9, the main shaft portion 24 c is passed through the shaft hole 20 a of the bearing protrusion 20 and the shaft through hole 21 a of the bearing piece 21, and the rotation preventing portion 24 a is inserted into the shaft of the bearing piece 22. By fitting in the fixing hole 22a, the cutting part 2 is pivotally supported at the tip of the tape guide rod 7 by the swing shaft 23 so as to be vertically rotatable.
[0014]
At this time, by fitting the shaft hole 25a of the tape guide roller 25 to the roller bearing portion 23b of the swing shaft 24, the tape guide roller 25 has a tip and a cutting portion of the tape guide rod 7 as shown in FIG. Between the two main bodies 9, it is rotatably supported by the swing shaft 24. In order to minimize the gap between the tip of the tape guide rod 7 and the tape guide roller 25, the tip surface 7c of the tape guide rod 7 is curved along the outer peripheral surface of the tape guide roller 25 as shown in FIG. I'm allowed. Further, a nut 26 is screwed onto the screw 24d of the main shaft portion 24c, and the bearing projection 20 is fastened with the nut 26, whereby the angle of the cutting portion 2 with respect to the tip of the tape guide rod 7 can be arbitrarily set. It is like that.
[0015]
As described above, since the cutting portion 2 is pivotally supported at the tip of the tape guide rod 7 so as to swing up and down, the tip of the tape guide rod 7 and the tape inlet 27 on the side of the cutting portion 2 (upper and lower tape guide plates). A gap is inevitably generated between the rear ends of the front and rear ends 18 and 19, and the direction of the tape inlet 27 varies depending on the angle of the cutting portion 2. Therefore, as shown in FIG. 3, the tip of the leaf spring-like tape guide tongue piece 28 is fixed to the lower surface of the tape guide plate 18 on the upper side of the cutting portion 2. The tape guide tongue 28 extends from the adhering portion onto the lid plate 7b of the tape guide rod 7, and is slidable in a tongue piece guide sheath (tongue piece guide portion) 29 fixed on the lid plate 7b. Is inserted.
[0016]
Accordingly, the tape 1 fed along the concave groove 7a of the tape guide rod 7 passes between the tape guide tongue piece 28 and the tape guide roller 25, and is guided by these to the tape introduction port 27 of the cutting portion 2. Led to. At this time, even if the cutting part 2 is straight with respect to the tape guide rod 7 as shown in FIG. 11, or is inclined downward as shown in FIG. 12, it is inclined upward as shown in FIG. However, since the tape guide tongue piece 28 is elastically deformed between the tip of the tape guide rod 7 and the tape inlet 27 of the cutting portion 2 so as to expand and contract according to the posture of the cutting portion 2, The guiding action of the piece 28 and the tape guide roller 25 is not changed, and the tape guide roller 25 is rotatable, so that the tape 1 can be smoothly introduced into the tape inlet 27.
[0017]
Since the cutting part 2 can swing up and down, the flexible shaft 8 is used to drive the movable cutter 15 in the cutting part 2 by the cutter driving mechanism 5 in the driving part 6 as described above. This flexible shaft 8 is a ready-made one in which a metal wire 8b is inserted into a plastic sheath 8a containing fibers. On the cutting part 2 side, the tip of the sheath 8a is attached to the main body 9 of the cutting part 2 using a nut 30. The front end of the metal wire 8b fixed to the rear surface and protruded from the front end of the sheath 8a is connected to the rotating frame 12 of the movable cutter 15 by the joint 31. On the other hand, on the drive unit 6 side, the base end of the metal wire 8b is connected to a linear motion actuator (such as an air cylinder or an electromagnet) (not shown) of the cutter drive mechanism 5. When this linear motion actuator reciprocates, the metal wire 8b slides within the sheath 8a, the rotating frame 12 rotates, and the movable cutter 15 moves up and down.
