Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for processing tape-shaped materials, and more particularly to an apparatus for processing very thin tape-shaped materials.

[0002]

2. Description of the Related Art When mass-producing thin plate-like products,
It is common practice to utilize tape-like materials. For example, when mass-producing thin disk-shaped products, a tape-shaped material is prepared in a wound state, the tape-shaped material is sequentially fed out from one end, and a predetermined punching process is performed to obtain a disk-shaped product. The tape-shaped material in the so-called "outer shell" state after punching is discharged as it is. As described above, the use of the tape-shaped material enables continuous processing, which is very efficient in mass production. Usually, such a tape-shaped material processing device is
A tape supply unit that sequentially supplies the tape-shaped material along its longitudinal direction, a tape processing unit that performs predetermined processing (for example, punching) on the tape-shaped material that is supplied from the tape supply unit, and this tape. The tape-shaped material processed in the processing unit is sent out in a predetermined discharge direction.

[0003]

In the above-described tape-shaped material processing apparatus, the tape-shaped material is sequentially fed from the tape supply section through the tape processing section to the tape discharge section along the longitudinal direction thereof. It will be. In this case, it is important to secure the positional accuracy of the tape-shaped material in the width direction (that is, the direction orthogonal to the feeding direction). When the tape-shaped material is fed so as to flow in the longitudinal direction, positional deviation in the width direction is likely to occur. When such a displacement occurs,
The processing position in the tape processing section is displaced. For this reason, correct processing cannot be performed and the yield is reduced. Therefore, in a general tape-shaped material processing apparatus, a pair of guide members are provided at predetermined intervals, and the tape-shaped material is inserted between the guide members to perform positioning. That is, the pair of guide members support both side portions of the tape-shaped material to perform accurate positioning in the width direction.

However, for a very thin film tape material, the conventional general positioning method using a guide member is not suitable, and the tape material may meander during running. For example, P with a thickness of about 50 μm
In a tape-shaped material made of ET film, even if an attempt is made to support both side portions by a pair of guide members, both side portions tend to warp, so that the guide member is easily climbed up while running, causing meandering. . As described above, with the conventional processing apparatus, it was very difficult to process a very thin film-shaped tape-shaped material while ensuring accurate positional accuracy in the width direction.

Therefore, an object of the present invention is to provide a tape-shaped material processing apparatus capable of ensuring accurate positional accuracy in the width direction even for a very thin film-shaped tape-shaped material.

[Work]

(1) According to the first aspect of the present invention, the tape ejecting portion is provided with the first clamping means and the second clamping means, and presses the tape-shaped material in the thickness direction to clamp it. You can In addition, since the tape-shaped material is clamped by at least one of the clamping means, the tape-shaped material is always processed, even when the processed tape-shaped material is delivered. The tape-shaped material is always sandwiched so that displacement does not occur in the width direction. Therefore, accurate position accuracy in the width direction can be ensured. By the backward movement operation of the second holding means, a force to move the tape-shaped material in a direction opposite to the discharging direction acts, but a force larger than this force is applied to the discharging direction. The tape-shaped material does not move backward if it is configured to act.

Example §1. Conventional Processing Apparatus Hereinafter, the present invention will be described with reference to illustrated embodiments. First, for reference, the principle of a conventional general tape-shaped material processing apparatus will be described with reference to FIG. As shown in FIG. 1, this conventional device is provided with a tape supply unit 10,
The tape processing unit 20 and the tape ejection unit 30 are basic elements. The tape supply unit 10 has a function of sequentially feeding the tape-shaped material 1 along the longitudinal direction thereof, and in the illustrated apparatus, the feeding reel 11 constitutes the tape supply unit 10. That is, the reel 1
The tape-shaped material 1 is wound around 1, and when one end of the tape-shaped material 1 is pulled out to the right in the figure, the pay-out reel 11 rotates in the direction of the arrow in the figure, and the tape-shaped material 1 is sequentially drawn out.
The tape processing unit 20 has a function of performing a predetermined processing on the tape-shaped material fed from the tape supply unit 10. In the illustrated apparatus, the tape processing is performed by the processing table 21 and the processing driving body 22. The part 20 is configured.
The tape-shaped material 1 fed out is passed through the upper surface of the processing table 21 from left to right in the figure. The processing driving body 22 is
The tape-shaped material 1 located directly below is driven in a vertical direction in the drawing (a supporting mechanism and a driving mechanism for the processing driving body 22 are omitted), and a predetermined processing is performed on the tape-shaped material 1. For example, when punching is performed, a male die is formed on the bottom surface of the machining drive body 22 and a female die is formed on the top surface of the machining table 21, and the machining drive body 22 is driven downward to form the tape-shaped material. 1 may be processed by sandwiching 1 between the male mold and the female mold. The tape discharge section 30 has a function of sending out the tape-shaped material 1 processed in the tape processing section 20 in a predetermined discharge direction. In the illustrated apparatus, a take-up reel 31.
The tape discharge unit 30 is configured by the above. That is, the processed tape-shaped material 1 is discharged to the right in the drawing and is wound up by the winding reel 31.

In the tape-shaped material processing apparatus having such a structure, after the processing drive member 22 is driven up and down to perform processing, the take-up reel 31 is rotationally driven in the direction of the arrow in the drawing to form the tape. By continuously performing the operation of feeding the strip-shaped material 1 rightward by a predetermined length, continuous processing becomes possible. At this time, as described above, it is important to secure the positional accuracy of the tape-shaped material 1 in the width direction (that is, the direction orthogonal to the feeding direction).
Therefore, it is general to provide a positioning means at a predetermined position on the processing table 21. Usually, a pair of guide members are provided at a predetermined interval, and a tape-shaped material is inserted between the guide members for positioning. FIG. 2 shows a cross section of the positioning means composed of a pair of guide members 23, and this figure corresponds to a cross section taken along a cutting plane orthogonal to the traveling direction of the tape-shaped material 1. The tape-shaped material 1 is supported by the guide members 23 on both sides on the upper surface of the processing table 21. The pair of guide members 23 are provided at intervals substantially equal to the width of the tape-shaped material 1, and the position of the tape-shaped material 1 in the width direction is accurately controlled by the pair of guide members 23.

By the way, such positioning in the width direction by the pair of guide members 23 is extremely effective for the ordinary tape-shaped material 1. Since the tape-shaped material 1 is accurately fixed at the position defined by the pair of guide members 23, no positional deviation occurs. However, such a positioning means does not work very effectively with a very thin flexible film tape material. For example, in the tape-shaped material 2 made of a PET film having a thickness of about 50 μm, both sides have a tendency to warp,
As shown in FIG. 3, there is a phenomenon that the guide member 23 is easily climbed up during traveling. In this way, when the phenomenon of riding on the guide member 23 occurs, the positioning accuracy in the width direction is significantly reduced, and the tape-shaped material 2 meanders during traveling. Such a meandering phenomenon is caused by the tape processing part 20.
It will hinder the correct processing in. For example,
In the process of manufacturing a thin-film disc-shaped product (such as a film stopper used for a container for seasonings, etc.), the meandering phenomenon causes the partially missing free material 3 as shown in FIG. 4 to be punched out. The present invention solves such a problem of the conventional device, and provides a tape-shaped material processing apparatus capable of ensuring accurate positional accuracy in the width direction even for a very thin film-shaped tape-shaped material. It is intended.

§2. Configuration of First Embodiment The structure and operation of the tape-shaped material processing apparatus according to the present invention will be described in detail below. FIG. 5 is a front view showing the basic configuration of a tape-shaped material processing apparatus according to an embodiment of the present invention.
This apparatus also has a tape supply unit 10, a tape processing unit 20, and a tape discharge unit 30 as main components. The tape supply unit 10 is similar to the above-described conventional device and is used as the pay-out reel 1
The tape processing section 20 is also composed of a processing table 21 and a processing driving body 22 as in the conventional device described above. The features of this device are:
It is in the configuration of the tape ejection unit 30. In the above conventional device,
The take-up reel 31 constitutes the tape ejecting section 30, but in this apparatus, the tape ejecting section 30 is constituted by the first nipping means 40, the second nipping means 50, the control means 60, and the rotating roller 70. ing.

Here, the first holding means 40 and the second holding means 50 are both a pair of holding plates capable of holding the tape-shaped material 2 while pressing it in the thickness direction thereof, and a pair of the holding plates. And a holding drive unit that moves the holding plate to a holding state or a released state. Here, the first holding means 40 is fixed to the processing table 21, but the second holding means 50 further includes a pair of holding plates along the discharge direction (that is, in the left-right direction in the drawing). ) Equipped with a reciprocating drive that reciprocates. Further, the control means 60 has a function of controlling the first nipping means 40 and the second nipping means 50, and the rotary roller 70 is always driven to rotate in the arrow direction in the figure. As will be described later, the tape-shaped material 2
Is always held by either one of the first holding means 40 or the second holding means 50, or both, so that the rotational movement of the rotating roller 70 causes the tape-shaped material 2 to move in the discharging direction. It does not fulfill the function of sending. In other words, the tape-shaped material 2 has the holding means 40, 50.
Since the roller is always sandwiched by, the rotating roller 70 simply idles. That is, the tape-shaped material 2 rides on the rotating roller 70 and is idle. The role of the rotating roller 70 will be described later.

The processing of the entire apparatus is the same as that of the above-mentioned conventional apparatus. That is, the tape-shaped material 2 fed from the tape supply unit 10 is processed by the tape processing unit 20 and discharged by the tape discharging unit 30. During the processing work in the tape processing unit 20, the tape-shaped material 2
Is stopped, and the processing drive body 22 is moved up and down to process a predetermined region of the tape-shaped material 2 located immediately below the processing drive body 22. After the processing, the tape-shaped material 2 travels to the right side in the drawing by a predetermined length and is discharged by the tape discharging unit 30, and the traveling is stopped again, and the next predetermined area is processed. In this way, continuous processing can be performed by alternately repeating processing and discharging of the tape-shaped material 2.

Next, the structure and operating principle of the tape ejecting section 30, which is a feature of the present invention, will be described. Figure 6
FIG. 6 is a principle diagram for explaining a basic configuration of a first holding means 40 and a second holding means 50. First pinching means 40
Is composed of a movable holding plate 41, a fixed holding plate 42, and a holding drive unit (not shown) that drives the movable holding plate 41 in the vertical direction in the drawing. Similarly, the second holding means 50 includes a movable holding plate 51 and a fixed holding plate 52.
And a holding drive unit (not shown) that drives the movable holding plate 51 in the vertical direction in the drawing.
In practice, the movable holding plate 41 is attached to the fixed holding plate 42 by some kind of support mechanism so as to be vertically slidable, and the movable holding plate 51 is vertically slidable. Further, although it is attached to the fixed holding plate 52 by some support mechanism, the illustration is omitted here because the figure becomes complicated here. Further, although an air pump or the like is provided as a holding drive unit for driving the movable holding plate 41 or the movable holding plate 51 in the vertical direction, the holding drive unit is also not shown.

FIG. 6 shows a state in which the movable holding plate 41 or the movable holding plate 51 is moving upward,
Here, this state will be referred to as a "released state". On the contrary, a state in which the movable holding plate 41 or the movable holding plate 51 is moved downward by driving an air pump or the like will be referred to as a “holding state”. The tape-shaped material 2 is inserted between the pair of holding plates as illustrated. Therefore,
In the released state as shown in FIG. 6, the tape-shaped material 2
Can be freely moved along the discharge direction, but in the sandwiched state, it is sandwiched by both sandwiching plates, and the position is fixed. Conversely, in the sandwiching state, the movable sandwiching plate is moved by the sandwiching drive unit such as an air pump so that a sufficient pressing force is applied in the thickness direction of the tape-like material 2 so that the position of the tape-like material 2 can be fixed. It is necessary to apply pressure in the direction of moving 41 or the movable holding plate 51 downward in the figure. In order to securely fix the tape-shaped material 2, it is preferable to form a material having a large friction coefficient such as silicon rubber on the lower surface of the movable holding plates 41, 51 or the upper surface of the fixed holding plates 42, 52. .

By the way, while the fixed holding plate 42 is fixed on the working table 21, the fixed holding plate 52 is slidable so that the fixed holding plate 52 can reciprocate on the working table 21 along the discharge direction. It is attached on top (the wording “fixing” of the fixed holding plate 52 is used to mean that no displacement occurs in the vertical direction in the drawing). Specifically, rails and the like are provided on the processing table 21 in the left-right direction in the drawing, a groove for fitting the rail is formed on the lower surface of the fixed holding plate 52, and if necessary, a bearing is interposed to connect the two. Just do it. However, here, in order to avoid making the figure complicated, these sliding mechanisms will be represented by wheels. Further, a reciprocating drive unit such as an air pump is required to reciprocate the fixed holding plate 52 in the left-right direction in the drawing, but the reciprocating drive unit is also not shown. After all, the first holding means 40 is fixed on the processing table 21, but the second holding means 50 is fixed.
Moves reciprocally on the processing table 21 along the discharge direction.

The control means 60 controls the first clamping means 40 and the second clamping means 50 to be in a clamping state or in a releasing state, and also controls the reciprocating movement of the second clamping means 50. Actually, it has a function of sending a predetermined electric signal to an air pump or the like which constitutes these drive systems. Next, what kind of control is performed by the control means 60 when the entire processing apparatus is operated will be described.

§3. Operation of the First Embodiment First, when the tape processing unit 20 is performing processing, that is, the processing drive body 22 moves up and down to perform some processing on the tape-shaped material 2 immediately below. Sometimes, the first holding means 40 and the second holding means 5
At least one of 0s is clamped to fix the tape-shaped material 2. In this embodiment, as shown in FIG. 7, the first clamping means 40 is clamped to fix the tape-shaped material 2 and the second clamping means 50 is released. In this way, if the tape-shaped material 2 is sandwiched, the tape-shaped material 2 is fixed during processing and no positional deviation occurs. It should be noted that in the following, the operation of feeding the tape-shaped material 2 in the discharge direction (right side of the drawing) will be described, and therefore, in FIG. 7 to FIG. 13, a part of the tape-shaped material 2 is painted black for easy understanding. I will mark it.

When the processing process is completed, the following discharging process is performed. This discharging process includes the forward movement of the first half,
The second half of the operation is the return path. First, the outward operation is performed as follows. First, as shown in FIG. 8, the second clamping means 50 is clamped. Then, as shown in FIG. 9, the first holding means 40 is brought into a released state. Thus, as shown in FIG. 10, while keeping the second holding means 50 in the holding state and the first holding means 40 in the released state,
The second holding means 50 is moved in the discharging direction (rightward in the figure) by a predetermined distance (a distance necessary for performing the next processing). As a result, the tape-shaped material 2 is fed by a predetermined distance in the discharging direction. The above is the outward operation. Next, the return path operation is performed as follows. First, as shown in FIG. 11, the first holding means 40 is put in the holding state, and subsequently, as shown in FIG. 12, the second holding means 50 is placed.
Is released. Thus, while keeping the first holding means 40 in the holding state and the second holding means 50 in the released state, as shown in FIG. 13, the second holding means 50 is in the direction opposite to the discharging direction (in the figure). Move it to the left) and return it to its original position. At this time, the tape-shaped material 2 has the first holding means 4
Since it is clamped and fixed by 0, the stationary state is maintained.

However, in this returning operation, although the second holding means 50 is in the released state, a frictional force acts on the tape-shaped material 2 in the moving direction of the second holding means 50. Will be done. In particular, when the tape material 2 is a very thin film material, the second holding means 5
With the movement of 0, the tape-shaped material 2 may be pulled back. In this case, since the tape-shaped material 2 is fixed by the first holding means 40, the first holding means 40
A slack is generated between the second holding means 50 and the second holding means 50, and an adverse effect such as wrinkles is caused. The rotating roller 70 in the apparatus shown in FIG. 5 plays a role of providing a reaction force against the pullback force. As described above, the rotating roller 70
However, due to the friction between the roller surface and the surface of the tape-shaped material 2, the tape-shaped material 2 is always subjected to a reaction force in the discharge direction. If this drag force is set so as to be larger than the above-mentioned pullback force, by the backward movement operation of the second holding means 50,
The tape-shaped material 2 is never pulled back.

After the tape-shaped material 2 is discharged by a predetermined distance by performing such forward and backward movement operations, the next processing step may be started again. In this way, by continuously repeating the working process and the discharging process, a continuous working process is performed. By the way, an important point here is that the tape-shaped material 2 is always clamped by either one or both of the first clamping means 40 and the second clamping means 50 in both the processing step and the discharging step. The point is that it is in a closed state. As long as such sandwiching is performed, the position of the tape-shaped material 2 in the width direction is maintained at the initially set position, and the positional deviation does not occur. Therefore, like the conventional processing apparatus, it is possible to prevent the occurrence of meandering and always perform correct processing.

§4. Configuration of Second Embodiment Next, a more practical embodiment of the present invention will be described with reference to FIG. The main structural elements of the device of this embodiment are the supply stand 100, the top plate 200, and the device main body 300.
And,

The supply stand 100 includes a column 110 and a delivery reel 120 supported by the column 110.
And a drive mechanism 130 including a motor, and the drive mechanism 1
And a power transmission belt 140 that transmits the rotational power of 30 to the reel 120. The tape-shaped material 2 is wound around the delivery reel 120. In this embodiment, as the tape-shaped material 2, a film-shaped tape having a three-layer structure of PET layer / aluminum layer / PET layer is used, and the width is 28 mm and the thickness is 50.
μm. The top plate 200 is fixed on the apparatus main body 300 by a column 210. The tape-shaped material 2 fed from the supply stand 100 is guided to the right side of the drawing through the positioning means 220 formed on the top surface of the top plate 200. To the right of the top plate 200 and the column 210,
The reversing rollers 230 and 240 are attached, and the traveling direction of the tape-shaped material 2 is reversed from the right to the left by the reversing rollers 230 and 240. The tape-shaped material 2 in which the traveling direction is reversed passes through the upper surface of the apparatus main body 300 from the right to the left in the figure, and is turned by the turning roller 310 to the lower side in the figure, and the first holding means 320 and the second holding means 320 are held. It is discharged between the means 330 and onto the floor. The above is the description of the components related to the traveling path of the tape-shaped material 2.

Next, constituent elements for processing the tape-shaped material 2 will be described. An upper drive device 250 is formed on the lower surface of the top plate 200.
0 has a function of driving the upper processing driving body 260 in the vertical direction in the drawing. On the other hand, inside the apparatus main body 300, as shown by cutting out a part, rails 340 are provided in the left-right direction in the drawing, and the lower drive device 350 is mounted on the rails 340. There is. The lower drive device 350 has a function of driving the lower processing driving body 360 in the vertical direction of the drawing, and also has a function of moving along the rail 340 in the horizontal direction of the drawing. A blade for punching out the tape-shaped material 2 in a circular shape is formed on the lower surface of the upper processing driving body 260. In addition, the lower processing driver 36
A structure for receiving this blade is formed on the upper surface of 0,
Further, a suction hole for sucking the object placed on the upper surface downward is formed. A suction mechanism is provided inside the lower processing driving body 360, and an object placed on the upper surface is suction-fixed by this suction mechanism.

A tension generating means 270 is provided on the left side of the top plate 200. This tension generating means 270
Is composed of a roller 271 and a support rod 272 that supports both ends of the roller 271. Support rod 27
2 is rotatably attached to the top plate 200. Therefore, the entire tension generating means 270 can swing in the direction shown by the arrow in the figure. Normally, the weight of the roller 271 pushes the tape-shaped material 2 downward, and has a function of generating tension on the tape-shaped material 2. Of course, when the roller 271 is lifted by hand, it can be lifted freely as shown by the broken line in the figure.

§5. Operation of the Second Embodiment The processing operation by this apparatus is performed as follows. First, in the processing step, in the state shown in the figure, the lower driving device 350 drives the lower processing driving body 360 to extend upward, and the upper surface of the lower processing driving body 360 contacts the lower surface of the tape-shaped material 2. To reach. On the other hand, the upper driving device 250 moves the upper processing driving body 260 downward, and the blade formed on the lower surface of the upper processing driving body 260 performs circular punching processing on the tape-shaped material 2. The punched circular free material 3 is placed on the upper surface of the lower processing driving body 360. At this time, if suction is performed by the suction mechanism in the lower processing driving body 360, it is blown away by wind or the like. Instead, the play material 3 is kept on the upper surface of the lower processing driving body 360. Then, the upper processing driver 2
The processing step is completed by returning 60 to the upper side and moving the lower processing drive body 360 downward to return it.

The discharging process is similar to that of the basic embodiment described above. That is, the first holding means 320 and the second holding means
The holding means 330 is the same as the first holding means 40 and the second holding means 50 in the above-mentioned embodiment,
Do exactly the same thing. However, in the above-described embodiment, the discharging direction is the right side of the drawing, but in this embodiment, the discharging direction is the lower side of the drawing. Therefore, the tape-shaped material 2 is sent toward the floor and discharged for a predetermined distance.
Of course, the tape-shaped material 2 is always the first clamping means 3
The tape-shaped material 2 is not displaced in the width direction because it is clamped by either one or both of the 20 and the second clamping means 330.

The controller 400, which is indicated by the alternate long and short dash line in the figure, includes a drive mechanism 130, an upper drive device 250,
A predetermined driving signal is given to the holding means 320, the second holding means 330, and the lower driving device 350 to control the above-described working process and discharging process.

§6. Advantages of the Second Embodiment The first advantage of this embodiment is that the rotating roller 70 in the device shown in FIG. 5 is unnecessary because the discharge direction is downward. The traveling direction of the tape-shaped material 2 after processing is changed vertically downward by the turning roller 310, but gravity acts on the tape-shaped material 2 inevitably, so that the tape-shaped material 2 is inevitably lowered, that is, discharged. The force to move in the direction acts. As described above, since the second holding means 330 moves upward in the figure by the backward movement operation, the pulling force acts on the tape-shaped material 2, but the tape-shaped material 2 faces downward due to its own weight. Since the total drag force is larger than this pullback force, the tape-shaped material 2 is not adversely affected by wrinkles. In other words, in the embodiment shown in FIG. 5, the discharge direction was horizontal, and therefore it was necessary to apply a reaction force by the rotating roller 70. However, in this embodiment, the discharge direction was set vertically downward, so that the tape shape was used. The self-weight of the material 2 makes it possible to exert a drag force, and the rotating roller 70 is unnecessary. The advantage of using the self-weight is not limited to the case where the discharge direction is set to the vertical direction, and is applicable to the case where the discharge direction is set to the direction inclined downward with respect to the horizontal plane. However, in order to obtain a sufficient drag force, it is most preferable to set the discharge direction to the vertical direction as in this embodiment.

The second advantage of this embodiment is that by providing the tension generating means 270, the tape-shaped material 2 can always be kept taut, and a smoother discharging operation can be performed. . As described above, the tension generating means 2
The roller 70 has a function of pressing the tape-shaped material 2 downward by the roller 271 which tends to hang down by its own weight and exerting a tension. Therefore, in the tape-shaped material 2,
It is always in tension. Second clamping means 330
When the tape-shaped material 2 is discharged by a predetermined amount by the above, the tension generating means 270 is lifted up by an amount corresponding to the discharged amount, and the state in which the tension is applied remains unchanged. In this embodiment, an automatic feeding mechanism for detecting the position of the tension generating means 270 and automatically feeding a predetermined amount of the tape-shaped material 2 from the supply stand 100 is provided. As described above, every time the tape-shaped material 2 is discharged in the discharging step, the tension generating means 2
70 is to be lifted upward, but the position of the tension generating means 270 is above a predetermined level (see, for example, FIG.
4) (equal to or more than the position indicated by the broken line in FIG. 4), this is detected by the photo sensor, and a signal indicating that is given to the controller 400. Upon receiving this signal, the controller 400 transmits a drive signal to the drive mechanism 130. In this way, the drive mechanism 130 is driven, and the rotational movement thereof is transmitted to the delivery reel 120 by the power transmission belt 140, the delivery reel 120 is moved in the direction indicated by the arrow in the figure, and the tape-shaped material 2 is delivered by a predetermined amount. It will be. This causes the roller 271 to return downward, so that the signal from the photo sensor is stopped and the controller 400 is stopped.
Stops the operation of the drive mechanism 130. With such a function, even when the device is continuously operated, the state in which the predetermined tension is applied to the tape-shaped material 2 is always maintained.

The third advantage of this embodiment is that the positioning means 220 can further improve the positioning accuracy of the tape-shaped material 2 in the width direction. A top view of the top plate 200 is shown in FIG. 15 to explain this function. As shown in this figure, the positioning means 220
Is composed of a pair of guide members 221 and 222. The pair of guide members 221 and 222 are fixed to the upper surface of the top plate 200 at a predetermined interval from each other. Tape-shaped material 2 unrolled through roller 271
(In the figure, only the position thereof is shown by a chain line) is guided to the reversing roller 230 through between the pair of guide members 221 and 222. A pair of guide members 221,
222 has a bilaterally symmetrical shape with respect to a center line indicated by a chain double-dashed line in the drawing, and is arranged at a bilaterally symmetrical position.
The tape-shaped material 2 has a pair of guide members 22 on both sides thereof.
It will be supported by the inner portion of 1, 222.

The important point here is the positioning means 22.
The frontage a of the introduction section at 0 is substantially equal to the width of the tape-shaped material 2, and the frontage b of the derivation section is set to be narrower than the width of the tape-shaped material 2. As a specific dimension, while the width of the tape-shaped material 2 is 28 mm, the frontage a of the introduction portion is 28 mm, which is the same as this width, and the frontage b of the delivery portion.
Is set to 18 mm, which is narrower than this. Further, the inner partial widths of the pair of guide members 221 and 222 are gradually reduced from the width a to the width b evenly in the left-right direction from the introduction portion (the portion having the width a) to the leading portion (the portion having the width b). ing. In other words, the inner portions of the pair of guide members 221 and 222 are in a katakana "C" shape. When the tape-shaped material 2 is passed through such positioning means 220,
At the introduction portion, as shown in the cross section of FIG. 16, the tape-shaped material 2 is held in a flat state between the pair of guide members 221 and 222. This is because the tape 27 is pushed down by the roller 271.
This is for riding on the top plate 200 while being guided from below to above. On the other hand, at the lead-out portion, as shown in the cross section of FIG. 17, both side portions of the tape-shaped material 2 are held in a state of being warped downward. This is because the inner part width of the pair of guide members 221 and 222 is gradually narrowed from the introduction part to the extraction part. The inventor of the present application has confirmed that the provision of such a positioning means 220 has the effect of further increasing the positional accuracy of the tape-shaped material 2 in the width direction.

The fourth advantage of this embodiment is that, as shown in FIG. 14, the tape-shaped material 2 introduced onto the top plate 200 is inverted by the inversion rollers 230 and 240. is there. That is, since the tape-shaped material 2 is made to make a U-turn and then guided to the processed portion, an empty space is secured at the position on the right side of the drawing. This empty space can be used as a space for carrying the loose material 3 separated from the tape-shaped material 2. As described above, by the processing step, the free material 3 punched in a circular shape is placed on the upper surface of the lower processing drive body 360, and the free material 3 is sucked downward. In this state, the lower processing driving body 360 is driven so as to be contracted downward, the lower driving device 350 is moved rightward in the drawing along the rail 340, and moved to the position shown by the broken line in the drawing,
If the lower processing driving body 360 is driven so as to extend upward, the loose material 3 placed on the lower processing driving body 360 can be conveyed to the upper surface position of the apparatus main body 300. Here, if the suction is stopped, the loose material 3 can be collected at this position, and if necessary, can be transferred from this position to another processing device. In this way, it is extremely effective to enhance the practical value by adopting a structure that allows the processed product (free material 3) to be smoothly transferred to the outside of the apparatus.

The present invention has been described above based on the illustrated embodiments, but the present invention is not limited to these embodiments and can be implemented in various modes other than this. In particular, in the above-described embodiment, the example in which the punching process is performed as the process for the tape-shaped material 2 has been described, but the present invention can be applied to a processing device that performs various other processes. The subject matter of the present invention is a mechanism for feeding the tape-shaped material 2 so as not to cause meandering in the tape-shaped material processing apparatus, and any processing may be actually performed.

As described above, in order to secure a sufficient holding force by the pair of opposed holding bodies, it is preferable that at least one of the holding bodies has a surface made of silicon rubber or the like. In this case, a dielectric such as silicon rubber has a property of easily being charged with static electricity, and when a PET film or the like is used as the tape-shaped material, the tape-shaped material may be adsorbed on the surface of the sandwich by the static electricity. . In order to avoid such an adverse effect, strippers 81 and 82 may be provided at both ends of the reciprocating movement path of the second holding means 50, as shown in FIG. 18, for example. In the example shown in FIG. 18, the holding plates 42 and 52 are made of metal, and the holding plates 41 and 5 are made of metal.
Since 1 is made of silicon rubber, a sufficient holding force is secured. However, since silicone rubber has a property of being easily charged with static electricity, when the holding plate 51 is moved upward to be in a released state, the tape-shaped material 2 is likely to be held while being attracted to the lower surface of the holding plate 51. To do. If the stripper 82 is provided as in this example, the tape-shaped material 2 can be separated from the lower surface of the sandwiching plate 51 at this time. Similarly, the stripper 81 is used for the holding plate 4
1 acts to separate the tape-shaped material 2 from the lower surfaces of the holding plate 1 and the holding plate 51 (at the position shown by the broken line in the figure).
