2. Description of the Related Art Sprocket holes formed in a tape-shaped material are used for punching a substrate area defined by the tape-shaped material itself in a predetermined pattern, printing on a printing machine, laminating, mounting chips, and the like. Then, the teeth of the sprocket engage when the tape-like material is fed by the rotation drive of the sprocket wheel disposed between the feeding device and the winding device. Usually, holes are opened at equal intervals on both longitudinal edges of the tape-shaped material (the former), or holes are formed at regular intervals on both long edges of the tape-shaped material and a required number of rows in the width direction. (The latter). The former is a 35 mm narrow tape-like object,
The latter is a wide tape-shaped material such as 48 mm, 70 mm, 96 mm, or 150 mm. In the case of this wide tape, a plurality of narrow tapes can be obtained from the tape by cutting. 2. Description of the Related Art Conventionally, a punching device for punching a sprocket hole is provided between a feeding mechanism (not shown) for feeding a material roll of a tape-like material and a winding mechanism (not shown) for winding the tape-like material. Have been. As shown in FIG. 6 and FIG.
02a holding the four corners of the movable mold 402 with the guide pins 40.
3, a linear guide 500 for guiding the die 400 along the feeding direction of the tape-shaped material T, A drive source 600 such as an air cylinder that horizontally reciprocates by the guide action of the linear guide 500 and a drive source (for example, an air cylinder) 700 that strikes the movable mold 402 are provided. This punching device lowers the movable mold 402 by the drive source 700 to pinch the tape-shaped material T, and at the same time, opens the sprocket hole H of the tape-shaped material T by the punch 402a. Reciprocate horizontally and feed out the tape-shaped material T by a predetermined amount,
The driving of the drive source 600 is stopped, and the mold is released by the repulsive force of the return spring 404 interposed on the outer periphery of the guide pin 403. At the same time, the mold 400 itself is returned to the initial position by the drive source 600. And the movable source 4
02, and then travels horizontally to feed out a predetermined amount of the tape-like material T. In other words, the perforation of the sprocket hole H into the tape-like material T and the feeding of the tape-like material T alternately in the form of a tapeworm. It is repeated.

[0003] However, in this structure in which the mold 400 itself in which the driving source (for example, an air cylinder or the like) 700 is mounted on the movable mold 402 is reciprocated in the form of a tapeworm, the apparatus itself becomes very large. Therefore, a punching mechanism (having a punch and a die having a desired cross-sectional shape) for punching a sprocket hole is fixed, and a sprocket wheel is provided downstream of the punching mechanism (a movable die holding the punch and a die are held). It is proposed to feed a tape-like object by engaging a sprocket hole to be drilled with a fixed type. By the way, since the teeth of the sprocket wheel cannot directly engage with the virgin tape (the tape-shaped material before sprocket hole drilling),
When a sprocket hole is punched in the virgin tape, it is absolutely necessary to engage the teeth of the sprocket wheel with the sprocket holes of the punched tape (tape having a sprocket hole). In that case, the perforated tape and the virgin tape are joined together, and the sprocket holes are pierced by the punching device in the virgin tape while the teeth of the sprocket wheel are engaged with the sprocket holes of the perforated tape and fed. . However, there is a problem in that the rigidity of the thick portion of the connecting portion applies an excessive load to the punch, or the double-hitting of the perforated sprocket hole due to the positional relationship of the connecting causes a biasing force to the punch and breaks the punch. It requires some ingenuity.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object a virgin tape (a tape-like material before sprocket hole perforation).
And without being affected by the connection with the perforated tape,
It is an object of the present invention to provide a sprocket hole punching device for punching a sprocket hole in a virgin tape while pulling with a perforated tape.

[0005]

Means for Solving the Problems As technical means taken to solve the above-mentioned object, a first aspect is a feeding mechanism for feeding a tape-like material from a raw material roll, and a winding mechanism for winding the tape-like material. A tension pulley that has a punching mechanism that opens a plurality of rows of sprocket holes at equal intervals in the longitudinal direction of the tape-like material between the mechanism and a tension pulley that can move vertically upstream and downstream of the punching mechanism. A tape-like material is wound over a tension pulley over the feeding mechanism and the winding mechanism, and a hole is punched by the punching mechanism between the downstream tension pulley and the punching mechanism. A sprocket wheel that engages with a sprocket hole to feed the tape-like material downstream is arranged, and moves the sprocket wheel closer to and away from the punching mechanism. As the position and horizontal variably, the punching mechanism to a movable mold for holding a punch, and the gist that it is composed of a stationary die for holding the die. The punching mechanism includes a non-perforated state (first stage) in which the punch is separated from the tape-shaped object to be perforated;
A non-perforated state in which the punch is not in contact with the tape-shaped object even though the tape-shaped object is sandwiched by the punch holder (stripper) at the lower end (second
Step) and a driving unit capable of setting the height to a punching state (third step) in which a tape-shaped object is pinched and punched by a punch holder (stripper) at the lower end. This drive unit is a controllable drive source such as a servo motor or a linear motor. It is preferable that the variable movement distance of the central axis of the sprocket wheel approaching / separating is an integral multiple of the sprocket hole pitch. In addition, a press roller for slightly pressing the tape-like material in the direction of the tooth root of the sprocket wheel can be moved up and down directly above the approach position and the separation position where the position of the center axis of the sprocket wheel is varied. It is more preferable if they are arranged. Further, a lower plate portion in which a guide table for guiding the tape-shaped object from the fixed mold is linearly extended toward the upstream side and the downstream side, and the lower surface of the guide rail slides on the guide rail. And a surrounding portion that bends from both front and rear edges of the lower plate portion and surrounds the longitudinal edge portion of the tape-like material via a slight clear France, and the guide table on the downstream side at the time of the approach. A shorter length that does not interfere with the sprocket wheel is more preferable.

(Function) (Claim 1) A sprocket hole punching device for a tape-shaped material according to the present invention is configured to connect a free end of a virgin tape wound in a roll shape to a feeding mechanism with an upstream tension pulley and a punching device. The movable mold is driven in a state where the movable mold is positioned just downstream of the fixed mold, and the movable mold is driven to the second stage (non-perforated state in which the tape-like material is held by the punch holder (stripper) at the lower end), and the winding is performed. The free end is joined to the free end of the perforated tape wound in a roll around the take-up mechanism and passing through the tension pulley on the downstream side. At this time, the position of the sprocket wheel is changed in the horizontal direction so as to be separated from the punching mechanism, and its teeth are engaged with the sprocket holes of the perforated tape, and in conjunction with the punching operation of the punching mechanism. The rotation drive of the sprocket wheel is continued until just before the vicinity of the joint portion reaches the sprocket wheel. Then, the movable mold is lowered again (either the second step or the third step may be used) to hold the tape-shaped material, and then the tension pulley on the downstream side is manually moved upward to release the tension. The position of the sprocket wheel is varied in the horizontal direction so as to approach the punching mechanism while avoiding the joint part by using the slack, and the teeth are engaged with the sprocket holes drilled on the virgin tape, and The sprocket wheel is driven to rotate in conjunction with the striking motion, and a sprocket hole is made in the virgin tape. In this way, the function that the position of the sprocket wheel can be changed in the horizontal direction so as to approach and separate from the punching mechanism, and the height at which the movable mold holds the tape-like material (fixed to the punch plate (stripper)) The second type of holding a tape-shaped object with a mold
Step 3) allows the sprocket holes to be continuously drilled in the virgin tape without being affected by the joint between the virgin tape and the perforated tape. (Claim 2) In the sprocket hole punching device for tape-shaped material according to the present invention, the variable movement distance of the center axis of the sprocket wheel is set to an integral multiple of the sprocket hole pitch. With such a configuration, the relative positional relationship of the sprocket wheel to the sprocket hole when separating (retreating) from and approaching the punching mechanism is the same. Therefore, when the tooth portion of the sprocket wheel is engaged with the sprocket hole of the drilled work and towed, the tooth portion of the sprocket wheel is engaged with the sprocket hole drilled on the virgin tape, and the tape (virgin tape) is moved downstream. Make the relative relationship between the teeth and the sprocket holes when sending the tape) the same (engage the teeth with the hole edges on the downstream side (winding mechanism side) of the sprocket holes) to eliminate the pitch deviation of the sprocket holes . (Claim 3) The sprocket hole punching device for tape-shaped material according to the present invention is characterized in that, in addition to claim 2, when the teeth of the sprocket wheel are engaged with the sprocket holes of the pierced tape and pulled, and when the virgin tape is pierced. The engagement height position of the sprocket hole with respect to the tooth portion when the same tooth portion is engaged with the sprocket hole and sent downstream is always the same for the fine pressing operation of the pressing roller. (Claim 4) The tape-shaped sprocket hole punching device according to the present invention is characterized in that, in addition to Claim 3, the minute Y-axis direction (in the feed direction) due to the separation of the feeding mechanism and the winding mechanism. The positional deviation of the tape-like object (in the direction perpendicular to the X-axis direction) is corrected by the linear guide action of the guide rail, so that the tape-like object can be fed into the punching mechanism with high precision in the X-axis direction. The free ends of the virgin tape and the perforated tape can be connected to each other by effectively utilizing the upper surface of the lower plate portion of the guide rail on the downstream side.

The procedure for perforating the sprocket holes H in the virgin tape 100 using the tape-shaped sprocket hole perforating apparatus constructed as described above will be described. First, the virgin tape 100 and the perforated tape 2 will be described.
After passing through the pulleys 16 and 16 and the guide pulleys 300 and 300, respectively, the free ends are joined together. This joining is performed on the upper surface of the lower plate portion 901 of the short guide table 900 on the downstream side. Naturally, the joining portion is located immediately downstream of the punching mechanism 5. Then, the movable mold 5a is controlled to move so that the punch holder (stripper) 5a 'at the lower end thereof and the fixed mold 5b
Is set to the second stage in which the virgin tape 100 is sandwiched between the sprocket wheel 4 and the actuator 10.
Are separated from the punching mechanism 5 as far as the first horizontal guide slot 31b permits, the teeth 4 'are engaged with the sprocket holes H of the perforated tape 200, and the perforated tape 200 is Preparatory setup for slightly pushing the tooth portion 4 'in the direction of the root is performed (see FIG. 1). And
The main switch is turned on and the sprocket wheel 4 is rotationally driven in conjunction with the punching motion of the punch 35, and the perforated tape 200 is fed out to the winding mechanism 3 while the sprocket hole H is punched in the virgin tape 100 (FIG. 4). (A)). If this feeding is continued, the joining portion reaches the sprocket wheel 4 and the feeding cannot be performed.
Therefore, before the connecting portion reaches the sprocket wheel 4, the main switch is turned off, and the driving of the punching mechanism 5 and the rotation of the sprocket wheel 4 are both stopped. The virgin tape 100 is held between the punch holder (stripper) 5a 'and the fixed mold 5b (see FIG. 4B).
At this time, the punch 35 may be in a perforated state in which the hole is in the sprocket hole H, or the punch 35 is not in the sprocket hole H, that is, the punch 35 is simply formed by the punch holder (stripper) 5a 'and the fixed mold 5b. It may be in a pinched state. That is, the second stage or the third stage may be used. Thereby, the virgin tape 100 is fixed and does not loosen. Then, the downstream arm 6 is artificially moved upward to release the tension by the tension pulley 16 (see FIG. 4B). Next, the pressing roller 800 is lifted, the actuator 10 is operated, and the first horizontal guide slot 31b is moved so as to approach the punching mechanism 5 via the lower portion of the joining portion.
Approach the sprocket wheel 4 as much as possible, engage the teeth 4 'with the sprocket holes H drilled in the virgin tape 100, and again press the virgin tape 100 slightly in the direction of the root of the teeth 4' with the pressing roller 800. Move (Fig. 4
(B)). As a result, the sprocket holes H of the perforated tape 200 and the sprocket holes H of the virgin tape 100 have their teeth as shown in the enlarged illustration of FIG. 4 (a) and the enlarged illustration of FIG. 4 (b). The same relationship can be established in which both the roots of the portion 4 'are engaged with the downstream (winding mechanism 3 side) hole edge of the sprocket hole H. Then, turn on the main switch again
Then, the sprocket wheel 4 is rotationally driven in conjunction with the stroke of the punch 35, and the piercing of the sprocket wheel 4 is continued while the virgin tape 100 is being fed. By doing so, the sprocket holes H can be perforated in the virgin tape 100 without causing pitch deviation.

S3 is a centering camera provided in the punching unit 15, which is arranged at a fixed distance of an integral multiple with respect to the punch axis, and always centers a sprocket hole H to be drilled. The feedback of the data to the control unit (not shown)
It is considered that the quantitative intermittent feed amount (feed amount) is corrected. S1 and S2 denote a pair of upper and lower position detecting sensors for detecting the other end side of each of the arms 6, 6, that is, the approach side end.
When the inner end on the approach side is detected by the lower position detection sensor S1, the feeding mechanism 2 and the winding mechanism 3 perform feeding and winding, and conversely, the same end is When the position is detected by the upper position detection sensor S2, the feeding and winding by the feeding mechanism 2 and the winding mechanism 3 are stopped.

In this embodiment, the embodiment in which the sprocket holes are opened at equal intervals near both longitudinal edges of the tape-like material is described in detail. It is equally useful to form holes at equal intervals on a number of rows in required positions in the width direction. Needless to say, in that case, the required number of sprocket wheels 4 are provided coaxially and parallel to the center shaft 14 correspondingly.

[0020]

As described above, according to the present invention, the position of the sprocket wheel can be changed in the horizontal direction so as to approach or separate from the punching mechanism, so that the ends of the perforated tape and the virgin tape are joined together. When the sprocket wheel teeth are engaged with the sprocket holes of the perforated tape and pulled to drill the sprocket holes by the punching mechanism on the virgin tape, the adverse effect of joining (the rigidity of the thick portion of the joining portion The sprocket holes can be drilled in the virgin tape without being subjected to excessive load or being hit twice by the sprocket holes that have been drilled due to the splicing position. It is. In addition, if the variable movement distance of the center axis of the sprocket wheel is set to an integral multiple of the sprocket hole pitch, the tooth root of the tooth portion is in the sprocket hole with respect to the sprocket hole of the perforated tape and the sprocket hole of the virgin tape. The same relationship that engages the hole edge on the downstream side can be obtained, so that sprocket hole drilling without deviation in pitch can be performed. In addition, when the sprocket wheel is moved closer to or away from the punching mechanism, a pressing roller for slightly pressing the tape-like material in the tooth root direction of the sprocket wheel is provided so as to be movable up and down. It is possible to prevent the tape from moving up and down when the tape moves up and down in the height range of the tooth portion, and it is possible to drill the sprocket hole with a more precise pitch. Also, a guide rail for linearly extending a guide table for guiding the tape-shaped material from the fixed die toward the upstream side and the downstream side is provided with a lower plate portion on which the lower surface of the tape-shaped material slides, and a lower plate portion of the lower plate portion. It is composed of a surrounding portion that bends from both front and rear edges and surrounds the longitudinal edge portion of the tape-like material via a slight clear France, and makes the downstream guide table short so as not to interfere with the sprocket wheel when approaching. In this case, the minute displacement in the Y-axis direction orthogonal to the feed direction due to the separation between the feeding mechanism and the winding mechanism is corrected in the case of claim 3, and the punching mechanism can be accurately controlled. The tape-shaped material can be fed (extended), and the virgin tape and the perforated tape can be easily connected using the upper surface of the lower plate portion of the short guide table on the short downstream side, so that workability is extremely high. Get better.

The procedure for perforating the sprocket holes H in the virgin tape 100 using the tape-shaped sprocket hole perforating apparatus constructed as described above will be described. First, the virgin tape 100 and the perforated tape 2 will be described.
After passing through the pulleys 16 and 16 and the guide pulleys 300 and 300, respectively, the free ends are joined together. This joining is performed on the upper surface of the lower plate portion 901 of the short guide table 900 on the downstream side. Naturally, the joining portion is located immediately downstream of the punching mechanism 5. Then, the movable mold 5a is controlled to move so that the punch holder (stripper) 5a 'at the lower end thereof and the fixed mold 5b
Is set to the second stage in which the virgin tape 100 is sandwiched between the sprocket wheel 4 and the actuator 10.

1b, the tooth portions 4 'are engaged with the sprocket holes H of the perforated tape 200 while being separated as much as possible, and the pressing roller 800 slightly presses the perforated tape 200 toward the root of the tooth portion 4'. (See FIG. 1). Then, the main switch is turned on, and the sprocket wheel 4 is rotationally driven in conjunction with the punching operation of the punch 35, and the virgin tape 1 is rotated.
At the time 00, the perforated tape 200 is fed out to the winding mechanism 3 while the sprocket hole H is being perforated (see FIG. 4A). If this feeding is continued, the joining portion reaches the sprocket wheel 4 and the feeding cannot be performed.
Therefore, before the connecting portion reaches the sprocket wheel 4, the main switch is turned off, and the driving of the punching mechanism 5 and the rotation of the sprocket wheel 4 are both stopped. The virgin tape 100 is held between the punch holder (stripper) 5a 'and the fixed mold 5b (see FIG. 4B).
At this time, the punch 35 may be in a perforated state in which the hole is in the sprocket hole H, or the punch 35 is not in the sprocket hole H, that is, the punch 35 is simply formed by the punch holder (stripper) 5a 'and the fixed mold 5b. It may be in a pinched state. That is, the second stage or the third stage may be used. Thereby, the virgin tape 100 is fixed and does not loosen. Then, the downstream arm 6 is artificially moved upward to release the tension by the tension pulley 16 (see FIG. 4B). Next, lift the presser roller 800, via the connecting together portions downward to actuate the actuator 10 to the sprocket wheel 4 as close as permitted by horizontal guide slots 31b to approach the punching mechanism 5 with virgin tape 100 Tooth portion 4 'in sprocket hole H

00 sprocket hole H and virgin tape 100
The same relationship can be established in which the roots of the teeth 4 ′ are both engaged with the hole edge of the sprocket hole H on the downstream side (the winding mechanism 3 side). Then, the main switch is turned on again, the sprocket wheel 4 is driven to rotate in conjunction with the punching movement of the punch 35, and the sprocket wheel 4 continues to be pierced while the virgin tape 100 is fed. By doing so, the virgin tape 10 can be formed without causing pitch deviation.
The sprocket hole H can be pierced to zero.
