  The invention described in Patent Document 3 and Patent Document 4 is a structure in which a long film is filled with a filling material and packaged, and the long film is conveyed by a roller to cut the horizontal seal portion. Since the long film does not sag due to the weight of the object, it can be cut. When the long film substrate is cut alone, it is long due to bending wrinkles or static electricity during unwinding. The scale film substrate is curled, and there is a problem that the film is wound on a roller when unwound to the cutter or not introduced straight into the cutter.

  The invention described in Patent Document 5 is provided with a guide plate that also serves as a fixed clamp facing the pressing plate. However, when cutting a long base material, as in the above case, when bending a curl or unwinding, The long base material adheres to the guide plate due to static electricity or the adhesiveness of the long base material, and problems such as poor conveyance and uneven cutting length occur.

  The invention described in Patent Document 6 is a configuration in which a long film substrate is conveyed by a clamp instead of a roller, and no particular problem occurs when the long film substrate is continuously conveyed. When cutting the material, the long film substrate curls due to bending wrinkles or static electricity during unwinding, and the long film substrate comes off the clamping means when unwinding to the cutter, or straight to the cutter It is presumed that the problem of not being introduced will occur.

  As described above, the present invention transports the long film in two stages, ie, the movement of the first transport clamp and the movement of the second transport clamp, so that the long film substrate comes off the clamp when unwinding to the cutter. There is no inconvenience that it is not introduced straight into the cutter, and it is possible to prevent the occurrence of trouble in conveying the long film base material and uneven cutting length. Further, the cut film base material does not accidentally drop, and it is possible to prevent the cut film base material from being adsorbed to the clamp or taken out and damaged when taken out.

Hereinafter, the cutting apparatus for a long film substrate according to the present invention will be described with reference to preferred examples. In a cutting device that unwinds a long film substrate such as paper, cloth, or resin wound in a roll and cuts it to a certain length, it causes problems such as conveyance failure of the long film substrate and uneven cutting length. Is a long film substrate cutting device that unwinds a long film base material wound in a roll shape and cuts it into a predetermined length, the long film base material wound in a roll shape. An unwinding means for supporting and unwinding the material, a fixed clamp for sandwiching and opening both surfaces of the unrolled long film base, and a long film provided so as to protrude from one central portion of the fixed clamp A cutter that reciprocates and cuts on one side of the substrate at right angles to the transport direction, and is provided at a position in front of the cutter on the transport path of the long film substrate, and both surfaces of the long film substrate How to transport by pinching and releasing A first conveyance clamp that can be reciprocated by a predetermined distance to the long film substrate, and is provided at a position beyond the cutter on the long film substrate conveyance path, and sandwiches and opens both sides of the long film substrate. A second transport clamp that can reciprocate by a predetermined distance in the transport direction is realized by transporting the long film in two stages: movement of the first transport clamp and movement of the second transport clamp.

  FIG. 1 is a schematic view showing a long film substrate cutting apparatus 10 according to Embodiment 1 of the present invention, and FIG. 2 is a schematic view seen from the A1 direction of FIG. 1. In this embodiment, a long film base is shown. The structure which descends | falls the material 11 to a perpendicular direction and conveys it is shown.

  The long film substrate 11 wound in a roll shape is supported by the unwinding means 12, and the long film substrate 11 unwound from the unwinding means 12 passes through the guide roller 13 in the vertical direction. It is transported down to. In the conveyance path of the long film base material 11, a fixed clamp 14 that sandwiches and opens both sides of the unrolled long film base material 11, and protrudes from a central portion on one side of the fixed clamp 14, and A cutter 15 is disposed that reciprocates on one side of the long film substrate 11 at right angles to the conveying direction.

  In addition, a first transport capable of reciprocating a predetermined distance in the transport direction by sandwiching and releasing both surfaces of the long film base 11 at a position before the cutter 15 on the transport path of the long film base 11. A clamp 16 is provided, and the long film base 11 can be reciprocated by a predetermined distance in the transport direction by sandwiching and releasing both sides of the long film base 11 at a position beyond the cutter 15 on the transport path of the long film base 11. A second transport clamp 17 is provided.

  The fixed clamp 14 is fixedly disposed in contact with one side of the long film base 11, and is in contact with one side of the long film base 11, similarly to the upper fixed clamp 14 a disposed on the upper side of the cutter 15. The fixed film 14b is disposed at a position opposite to the lower fixed clamp 14b disposed below the cutter 15 and the upper fixed clamp 14a and the lower fixed clamp 14b. It is comprised from three members with the movable side fixed clamp 14c which can move orthogonally to.

  Here, the shape of the cutter 15 protruding from between the upper fixed clamp 14a and the lower fixed clamp 14b is not particularly limited as long as it can cut the long film base material 11, but since it is reciprocated, it is a disc. A cutter is preferred. Further, the width dimension of the fixed clamp 14 is formed larger than the width dimension of the long film base material 11 so as not to interfere with the long film base material 11 when the cutter 15 is stopped. And, when the cutter 15 is stopped, it is formed so as to be retracted to the side of the long film base 11. Further, the movable side fixed clamp 14c facing the cutter 15 so as not to interfere with the movable side fixed clamp 14c when the cutter 15 reciprocates in a state where the fixed clamp 14 sandwiches the long film substrate 11. Is provided with a concave groove 14d.

  The lower fixing clamp 14b is provided with a suction port 18 of a suction means for sucking and holding the cut film substrate as will be described later. Further, air that injects air to the long film holding portion of the fixed clamp 14 excluding the suction port 18 and the long film holding portion of the first transfer clamp 16 toward the transfer direction of the long film substrate, respectively. An air nozzle 19 is arranged as a jetting means.

  Next, according to FIGS. 1-8, operation | movement of the cutting apparatus 10 of the elongate film base material which concerns on Example 1 is demonstrated. For convenience of explanation, the air nozzle 19 is not shown in FIG.

As shown in FIGS. 1 and 2, all the clamps of the fixed clamp 14, the first transport clamp 16, and the second transport clamp 17 are opened, and the leading end portion of the long film substrate 11 is introduced into the fixed clamp 14. First, as shown in FIG. 3, the first transport clamp 16 is closed to sandwich both surfaces of the long film base 11.

  Then, as shown in FIG. 4, the first transport clamp 16 is moved by a predetermined distance in the transport direction (downward in the drawing) while holding the long film base material 11, and the leading end of the long film base material 11 is moved. Passes through the fixed clamp 14 and the cutter 15 until reaching the second transport clamp 17, and the second transport clamp 17 is closed to sandwich both ends of the long film base 11.

  Subsequently, as shown in FIG. 5, the first transport clamp 16 is opened to release the holding of the long film base 11, and the second transport clamp 17 holds both sides of the long film base 11. The second transport clamp 17 is moved by a predetermined distance in the transport direction. In this way, the long film base 11 is transported by a certain length L in two stages of movement of the first transport clamp 16 and second transport clamp 17.

  And as shown in FIG. 6, while moving the said 1st conveyance clamp 16 to a reverse direction with respect to a conveyance direction, while returning the original position, the fixed clamp 17 is closed and both surfaces of the elongate film base material 11 are clamped. . Subsequently, the second transport clamp 17 is opened, and as shown in FIG. 7, the second transport clamp 17 is moved in the direction opposite to the transport direction to return to the original position.

  In this state, as shown in FIG. 8, the cutter 15 moves on one side of the long film base material 11 at a right angle to the transport direction, and cuts the long film base material 11 into a fixed length L. In addition, although the moving distance of the said 1st conveyance clamp 16 and the movement distance of the 2nd conveyance clamp 17 are set to the cutting length of the elongate film base material 11, it does not reach the fixed length L by one movement. Repeats the above operation until the long film substrate 11 can be conveyed by a certain length L.

  Simultaneously with the cutting, the suction means provided on the lower fixed clamp 14b is operated to suck and hold the cut film substrate from the suction port 18. Although this suction means is not essential, when the long film base 11 is transported while being lowered in the vertical direction as in the present embodiment, the cut film base is dropped and scattered around. Therefore, providing the suction means is extremely effective for preventing the film base material from falling after the cutting.

  And when the film base material after the cutting is removed, the suction of the suction means is stopped by detection of a pressure switch (not shown). If the cut film base material is taken out, the initial state shown in FIG. 3 is obtained again.

  Here, when the long film base material 11 has adhesiveness, when the long film base material 11 is sandwiched between the first transport clamp 16 and the second transport clamp 17 or the fixed clamp 14, it is long. The length film base material 11 may adhere to the clamping part of each clamp. In this case, even if the clamps are opened and the clamping is released, the long film base material 11 is not separated from the clamps, and the long film base material 11 cannot be conveyed.

  For this reason, the mesh or the surface is roughened at the long film holding portion of the first and second transport clamps 16 and 17 and the long film holding portion of the fixed clamp 14 excluding the suction port 18. A release film (not shown) is adhered. By sticking the release film to each clamp, it is possible to prevent the long film substrate 11 from sticking to each clamp.

Alternatively, as shown in FIGS. 1 and 2, the first and second transport clamps 16, 17
An air nozzle 19 may be provided at each of the long film holding positions of the long film and the long film holding positions of the fixed clamp 14 excluding the portion of the suction port 18. According to this structure, air is jetted toward the conveyance direction of the long film base material 11 at the moment when each clamp “releases” the long film base material 11 from “holding”.

  Therefore, even if the long film base 11 is in close contact with each clamp, the long film base 11 is separated from each clamp very easily and quickly by injecting air from the air nozzle 19 for about 3 seconds. Can do.

  Thus, when a release film is stuck to each clamp or an air nozzle 19 is provided so that each clamp is released after sandwiching the long film base 11, the long film The base material 11 can be prevented from sticking to each clamp, the long film base material 11 can be smoothly and stably conveyed, and the cutting length can be made uniform accurately.

  Further, as described above, the cutter 15 for cutting the long film base material 11 protrudes from the central portion on one side of the fixed clamp 14, and in two stages of movement of the first conveyance clamp 16 and movement of the second conveyance clamp 17. The long film substrate 11 is conveyed by a certain length L. For this reason, the tip portion of the long film base 11 remains in the fixed clamp 14 between the upper end of the upper fixed clamp 14a and the cutter 15, and even if curling occurs in the long film base 11, the curl Remains in the fixed clamp 14, and the distal end portion of the long film base 11 does not come off the fixed clamp 14.

  Therefore, unlike the conventional type, there is no problem that the leading end portion of the long film base is not introduced straight into the cutter. In addition, since there is no roller that rotates by power in the transport path of the long tape base material 11, the possibility that the long film base material 11 is caught due to bending wrinkles, static electricity at the time of unwinding, adhesiveness, etc. is eliminated. can do.

  FIG. 9 is a schematic view showing a long film substrate cutting apparatus 11 according to Embodiment 2 of the present invention, and FIG. 10 is a schematic view seen from the A2 direction of FIG. Are given the same reference numerals, and redundant description will be omitted.

  The difference from the configuration of the first embodiment is that a flat protrusion 26a is projected from a first conveyance clamp 26 provided above the fixed clamp 14, and a second conveyance clamp provided below the fixed clamp 14. Reference numeral 27 denotes two points that the long film base material 11 is divided in the width direction.

  The first transport clamp 26 is provided at a position in front of the cutter 15 on the transport path of the long film substrate 11, and has a flat plate shape along the transport direction (downward direction in the drawing) at the left and right positions in the width direction. Protrusions 26a are provided so as to be able to reciprocate by a predetermined distance in the transport direction by sandwiching and opening both sides of the long film base 11. As will be described later, when the first transport clamp 26 sandwiches and transports the long film substrate 11, the flat projection 26 a moves over the cutter 15 in the direction of the second transport clamp 27. It is configured.

On the other hand, the 2nd conveyance clamp 27 is divided | segmented into the width direction of the elongate film base material 11, and is parallel to both surfaces of the elongate film base material 11, and a right angle with respect to a conveyance direction in the state which the clamp was open | released. Reciprocating motion is formed in the direction. As will be described later, when the long film base material 11 is being transported, the second transport clamp 27 is separated from the long film base material 11 in the width direction of the long film base material 11 so as to be separated from the long film base material 11. When the second transport clamp 27 sandwiches the long film base 11 while avoiding interference, the second transport clamp 27 is configured to approach the inner side in the width direction of the long film base 11.

  Next, according to FIGS. 9-15, operation | movement of the cutting apparatus 10 of the elongate film base material which concerns on Example 2 is demonstrated. For convenience of explanation, the air nozzle 19 is not shown in FIG.

  As shown in FIGS. 9 and 10, all the clamps of the fixed clamp 14, the first transport clamp 26, and the second transport clamp 27 are opened, and the second transport clamp 27 is in the width direction of the long film substrate 11. From the initial state where the distal end portion of the long film base material 11 is introduced into the fixed clamp 14, the first transport clamp 26 is first closed to close the long film as shown in FIG. The both surfaces of the base material 11 are clamped. At this time, the flat projection 26 a of the first transport clamp 26 sandwiches the relatively long end portion of the long film substrate 11.

  Then, as shown in FIG. 12, the first transport clamp 26 is moved by a predetermined distance in the transport direction (downward in the figure) while holding the long film base material 11 so that the flat projection 26a is fixed. It is transported over the clamp 14 and the cutter 15 until the leading end of the long film substrate 11 reaches the second transport clamp 27. Subsequently, the second transport clamp 27 approaches the both sides of the long film substrate 11 in a direction perpendicular to the transport direction, closes the second transport clamp 27, and covers both ends of the front end of the long film substrate 11. Hold it.

  Subsequently, as shown in FIG. 13, the first transport clamp 26 is opened to release the holding of the long film substrate 11, and at the moment of releasing the long film substrate 11 from “holding”, Air is ejected from the air nozzle 19 shown in FIGS. 9 and 10 for about 3 seconds. Thus, by ejecting air when each clamp is opened, the long film base 11 can be separated from each clamp very easily and quickly.

  As in the first embodiment, a mesh or a long film sandwiching portion of the first and second transport clamps 26 and 27 and a long film sandwiching portion of the fixed clamp 14 excluding the portion of the suction port 18 are respectively meshed. A release film (not shown) having a rough surface may be pasted. Also in this structure, the long film base material 11 becomes difficult to adhere to the clamping part of each clamp, and the long film base material 11 can be separated from each clamp very easily and rapidly.

  After the first transport clamp 26 releases the holding of the long film base material 11, the second transport clamp 27 is moved in the transport direction with the second transport clamp 27 holding both surfaces of the long film base material 11. Move it a predetermined distance. In this way, the long film base 11 is transported by a certain length L in two stages of movement of the first transport clamp 26 and second transport clamp 27.

  And while moving the 1st conveyance clamp 26 to a reverse direction to a conveyance direction and returning to the original position, the fixed clamp 17 is closed and both surfaces of the elongate film base material 11 are clamped. Subsequently, the second transport clamp 27 is opened, and as shown in FIG. 14, the second transport clamp 27 is parallel to both surfaces of the long film base 11 and separated in the direction perpendicular to the transport direction. While the second transport clamp 27 maintains the relative distance from the long film substrate 11, the first transport clamp 26 returns to the position where the leading end portion of the long film substrate 11 is transported.

  In this state, the cutter 15 moves on one side of the long film base material 11 at a right angle to the transport direction, and cuts the long film base material 11 into a fixed length L. In addition, although the movement distance of the said 1st conveyance clamp 26 and the movement distance of the 2nd conveyance clamp 27 are set to the cutting length of the elongate film base material 11, it does not reach the fixed length L by one movement. Repeats the above operation until the long film substrate 11 can be conveyed by a certain length L.

  In the same manner as in Example 1, simultaneously with the cutting, the suction means provided in the lower fixed clamp 14b is operated to suck and hold the cut film substrate from the suction port 18. And when the film base material after this cutting is removed, it comprises so that the suction of the said suction means may be stopped by the detection of a pressure switch (not shown).

  As described above, the second embodiment of the present invention is configured such that the first transport clamp 26 transports the fixed film 14 and the cutter 15 to the second transport clamp 27 while holding the long film base material 11 therebetween. Even if the leading end portion of the long film base 11 is detached from the fixed clamp 14, since it is introduced between the fixed clamps 14 by the first transfer clamp 26, more stable transfer can be obtained. This configuration is effective when the long film base 11 is relatively sticky or is easily charged with static electricity. Further, the present invention can be applied to a case where, for example, the paper is transported in a horizontal direction other than the one in which the transport direction is lowered in the vertical direction.

  Further, since the first transport clamp 26 exceeds the fixed clamp 14 while holding the long film base material 11, the configuration of the fixed clamp 14 is, for example, as shown in FIGS. 15 (1) to (2). If it is the structure which opens to both sides with respect to the film base material 11, the space | interval of the upper and lower side fixed clamps 14a and 14b and the cutter 15 and the movable side fixed clamp 14c will be widely open | released, the said 1st conveyance clamp 26 and flat plate This is even more preferable because there is no possibility that the protrusion 26a interferes.

Application examples

  FIG. 16 shows an application example when the configuration of Example 2 is used for cutting a dry film photoresist used in a printed circuit board manufacturing process, for example.

  A dry film photoresist generally has a three-layer structure of a base film, a photoresist, and a cover film. When laminating to a printed board, the cover film is peeled off and laminated. Therefore, when used in dry film photoresist lamination on a printed circuit board, it is reasonable to combine cutting and peeling of the cover film.

  Therefore, the roll-shaped long film substrate 11 on which the dry film photoresist having the above three-layer structure is formed is supported by the unwinding means 12 described above, and the cover film is separated when the guide roller 23 is passed. The cover film thus peeled off is wound up by the winding means 24. The long film base material 11 after the cover film is peeled off is cut by the same operation as in the second embodiment. Further, when the cover film is peeled off from the dry film photoresist, static electricity is remarkably charged. Therefore, the static electricity removal bar 25 can be installed after the cover film is peeled off to remove static electricity.

   According to the configurations of Example 1 and Example 2 described above, in the present invention, it is possible to cut a long film substrate of approximately 0.02 to 0.25 mm, although it depends on the material and hardness of the film substrate. Is possible.

   It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
