Description

  The present invention relates to a film handling apparatus that handles a film in cooperation with a pressing cylinder having a notch, and more particularly to a film transfer apparatus.

  For example, as disclosed in Patent Document 1 and Patent Document 2, a cold foil transfer device for a sheet-fed printing machine winds from a supply reel between a rubber cylinder wound with a blanket and an impression cylinder holding a sheet. By transferring the cold foil that is taken out under the rotation of the two cylinders, the foil (aluminum vapor deposition layer) of the cold foil is transferred to the area of the sheet where the adhesive has been previously applied. After the transfer, the cold foil is wound on a take-up reel together with a base film called a carrier, and becomes waste. From the unwinding reel to the take-up reel, the cold foil is kept at an appropriate constant tension and is fed out at the same speed as the circumferential surface of the rubber drum. The cold foil is obtained by winding a base film made of a resin or the like in a layer shape of a foil made of a metal or the like via a release layer or the like. Further, as disclosed in Patent Document 3, for example, there is an apparatus that performs film transfer type transparent hologram processing.

JP 2008-279769 A ([0060] to [0063], [FIG. 4]) JP 2009-6702 ([0034], [FIG. 2]) WO2008 / 084191 JP 2009-029110 A JP 2008-296448 A

  By the way, because the machine operation work is inappropriate, for example, a film that has been partially cut off or a film that has been suddenly attached with an adhesive tape piece has entered the rubber cylinder or has been wound up. If the take-up reel (paper tube) is idle on the shaft, an accident may occur in which the film is caught in the rubber cylinder.

  More specifically, for example, if an operator forgets to perform an air pressure filling operation to clamp an air shaft that is clapped to a take-up reel (paper tube), even if the machine is operated, the machine The take-up reel cannot be taken up and the film begins to sag. As another example, when the sheet-fed printing press is operated without using a film transfer device and only printing is performed, it is desirable to remove the film passing between the rubber cylinder and the impression cylinder. However, it is possible to operate the sheet-fed printing machine by simply removing the cylinder from the cylinder while leaving the film between the cylinders, and omitting this operation. You may end up driving. If the film transfer device is switched off at this time, the film transfer device cannot activate the tension control, and the film that cannot keep the tension constant is gradually slackened by the idle rotation of the rubber cylinder, and then the rubber cylinder continues to rotate. An enormous length of film is wound.

  When the film winds around the rubber cylinder, an excessive bending load is generated on both the cylinder of the rubber cylinder and the impression cylinder, the cylinder is bent, the cylinder cannot rotate and begins to slide between the gears, It becomes a fatal accident in which the rubber cylinder is damaged due to interference with the rubber cylinder, and production must be stopped immediately.

  Then, an object of this invention is to provide the film handling apparatus which can prevent the bad influence to each part by winding in the rotary body of a film, and can avoid production stop beforehand.

FIG. 13 is a graph showing a comparison between the case where there is a gap cover of the film span length when passing through the notch portion and the case where there is no gap cover.

  As shown in FIG. 1, holding nail devices (sheet holding means) 10a and 10b for holding the front end side of the sheet P so as to support the sheet P are supported on the outer peripheral surface. The adhesive corresponding to the pattern is transferred in advance from the sheet feeding device via the adhesive transfer device to the upstream side of the impression cylinder (conveyance drum) 12 provided in each of the two notches 11a and 11b formed at symmetrical positions. The transfer cylinder 13 that transfers the sheet P to the impression cylinder 12 is opposed to the transfer cylinder 13.

  On the downstream side of the transfer cylinder 13 in the conveying direction of the sheet P of the impression cylinder 12, the winding is composed of a winding bar or the like that holds the end of the blanket B so that the blanket B is supported on the outer peripheral surface. A rubber cylinder (pressing cylinder: rotating body) 16 provided with the device 14 in a notch 15 formed on the outer peripheral surface is opposed. A transfer cylinder 17 that delivers the sheet P from the impression cylinder 12 to the paper discharge device is opposed to the impression cylinder 12 downstream of the rubber cylinder 16 in the conveyance direction of the sheet P.

  Further, a cold foil (film) C, in which a foil made of metal or the like is provided in a layer shape on a base film made of resin or the like via a release layer or the like, is wound into a roll shape, A single winding or a plurality of windings spaced apart from each other by a predetermined distance in the axial direction are rotatably supported via an unwinding reel 19. Below the unwinding reel 19, a winding shaft 21 for winding the single-winding or multiple-winding cold foil C through the winding reel 20 is disposed.

  Then, the single or plural cold foils C unwound from the unwinding shaft 18 are shared by the two dancer rollers 23a and 23b in the case of plural windings after passing through the guide roller 22. In the case of a single volume, the first dancer roller section 24 that adjusts the tension via either one of the two dancer rollers 23a and 23b and the single dancer roller 25 arranged downstream thereof The reel tension adjusting mechanism 27 including the second dancer roller portion 26 for adjusting the tension absorbs the inherent tension fluctuation in the cold foil C of each winding.

  The tension-adjusted cold foil C is pulled by a pair of pinch rollers 28, passes through a feeding side of a transfer tension adjusting mechanism 30 described later, passes between the pressure drum 12 and the rubber drum 16, This time, after passing through the collection side of the transfer tension adjusting mechanism 30, it is pulled by a pair of pinch rollers 31 and taken up by the take-up shaft 21 through guide rollers 32a and 32b. In the figure, reference numerals 37 to 40 denote guide rollers.

  In the transfer tension adjusting mechanism 30 described above, the dancer roller 35a disposed between the two guide rollers 33a and 34a on the feeding side can be swung by the dancer arm 36a, and the two guides can also be provided on the collecting side. The dancer roller 35b arranged between the rollers 33b and 34b is also swingable by the dancer arm 36b, and the two dancer rollers 35a and 35b are swung so that it is cold on the feeding side and the collecting side. The transfer tension is set while absorbing fluctuations in the tension of the foil C.

  After the blanket B of the rubber cylinder 16 presses the cold foil C against the sheet P supported by the impression cylinder 12 and transfers the foil of the cold foil C to the sheet P, the rubber cylinder 16 When the cutout portion 15 and the cutout portions 11a and 11b of the impression cylinder 12 face each other, the dancer arms 36a and 36b swing, and the cold foil C between the guide rollers 33a and 34a and between the guide rollers 33b and 34b is formed. Dancer rollers 35a and 35b are movable so that the travel route (length) can be changed.

  Thereby, tension can be applied while absorbing fluctuations in tension generated at the notch, and the film tension at the transfer portion can be set stably.

  As shown in FIGS. 2 to 7, the cutout portion 15 of the rubber cylinder 16 shields the holding-side winding bar 41 a and the buttocks-side winding bar 41 b and the like in the blanket B of the winding device 14. A gap cover 42 is provided.

  The gap cover 42 includes a guide peripheral surface portion 42a having substantially the same curvature as the pressing peripheral surface portion of the rubber drum 16 (strictly, the outer surface of the blanket B), and the same pressure drum of the gripper claw devices 10a and 10b of the pressure drum 12. A shielding peripheral surface portion 42b lowered from the guiding peripheral surface portion 42a to the inside of the cutout portion 15 to avoid interference with a claw (protruding portion) 43 (see FIG. 2) protruding from the outer surface is a connecting plate portion 42c. It is connected in the circumferential direction via.

  The gap cover 42 can be attached and detached by engaging and disengaging pins with respect to the rubber cylinder 16 at both ends in the cylinder axis direction. That is, holding plates 45a and 45b are coupled to the inner surfaces of the bearer portions 44a and 44b provided at both ends of the rubber cylinder 16 by bolts 46a and 46b, and two pin holes 47a and 47b are formed in these holding plates 45a and 45b. Formed one by one.

  On the other hand, fixing pins 48a and 48b that can be engaged with and disengaged from the pin holes 47b of the holding plate 45b are attached to the back surface of the gap cover 42 via brackets 49a and 49b on one end side. The fixing pin 48a which can be engaged / disengaged with one of the pin holes 47b and the bracket 49a thereof correspond to the guide peripheral surface portion 42a, and the fixing pin 48b which can be engaged / disengaged with the other of the pin holes 47b and the bracket 49b thereof are the peripheral surface portion 42b for shielding. It is attached corresponding to each. In the illustrated example, tapered taper pins are used as the fixing pins 48a and 48b.

  On the other end side, movable pins 50a and 50b that can be engaged and disengaged with respect to the pin hole 47a of the holding plate 45a are attached via brackets 52a and 52b. The moving pin 50a and its bracket 52a that can be engaged and disengaged with one of the pin holes 47a correspond to the guide peripheral surface portion 42a, and the movable pin 50b and its bracket 52b that can be engaged and disengaged with the other of the pin holes 47a are the shielding peripheral surface portion 42b. It is attached corresponding to each.

  In the illustrated example, the brackets 52a and 52b are formed in a U-shaped cross section including front support portions 52a1 and 52b1, rear support portions 52a2 and 52b2, and connecting portions 52a3 and 52b3, and are fixed to the back surface of the gap cover 42. Has been. The moving pins 50a and 50b are prevented from rotating in the front support portions 52a1 and 52b1 by pins 53a and 53b (through the long holes 51a and 51b of the moving pins 50a and 50b) in the trunk axis direction. That is, the guide rod portions 54a and 54b attached to the rear end surfaces penetrate the rear support portions 52a2 and 52b2 so as to be slidable in the barrel axis direction when slidably penetrating in the direction of inserting into and removing from the pin hole 47a. Is done.

  The guide rod portions 54a, 54b are wound with compression coil springs 55a, 55b with one end side carried by the front support portions 52a1, 52b1 and the rear end side carried by the rear support portions 52a2, 52b2. Accordingly, when the gap cover 42 is attached, the moving pins 50a and 50b are always urged in the protruding direction so as to be able to engage with the pin holes 47a. Tapered taper pins are used as the moving pins 50a and 50b.

  Further, on the back surface of the gap cover 42, the base end portions of the leaf springs 56a and 56b for restricting the backward movement of the guide rod portions 54a and 54b at positions corresponding to the guide rod portions 54a and 54b are brackets 57a. , 57b and fixed with bolts 58a, 58b. That is, when the gap cover 42 is attached, the tip ends of the leaf springs 56a and 56b are in contact with or close to the rear end surfaces of the guide rod portions 54a and 54b to restrict the retreat thereof (the solid line state in FIGS. 3 and 4). Reference), while maintaining the state in which each moving pin 50a, 50b is engaged with the pin hole 47a and disabling the removal of the gap cover 42, by forcibly bending the tip side of the leaf springs 56a, 56b, The rear end surfaces of the guide rod portions 54a and 54b allow the retraction without interfering with the tips of the leaf springs 56a and 56b (see the two-dot chain line state in FIGS. 3 and 4), and the movable pins 50a and 50b are pinned. The gap cover 42 can be removed by slipping out of the hole 47a.

  Therefore, when the gap cover 42 is attached, the moving pins 50a and 50b are inserted into the pin holes 47a of the holding plate 45a while pushing down the distal ends of the leaf springs 56a and 56b, for example, and the gap cover 42 is inserted into the gap cover 42 in FIGS. It is attached by inserting the fixing pins 48a and 48b into the pin holes 47b of the holding plate 45b while being fitted into the rubber cylinder 16 while being pushed to the middle left. On the other hand, when removing the gap cover 42, the front end side of the leaf springs 56a and 56b is pushed down, for example, the gap cover 42 is slid leftward in FIGS. 3 and 4, and the fixing pins 48a and 48b are pulled up. Can be removed.

  Further, the gap cover 42 is a press-worked product such as SUS304, but the surface of the guide peripheral surface portion 42a is subjected to surface processing having irregularities, or a flexible material having irregularities (felt cloth or the like) is stuck. The

  In addition, a plurality of window holes 60 (10 in the illustrated example) are formed in the shielding peripheral surface portion 42b of the gap cover 42 so as to be spaced apart from each other by a predetermined distance in the trunk axis direction, and on the back side of the shielding peripheral surface portion 42b. As shown in FIG. 8, a plurality of (10 in the illustrated example corresponding to 10 window holes 60) reflectors (mirrors: reflectors) 61 are shielded so as to close each window hole 60. It is supported by a single presser plate 63 coupled to the peripheral surface portion 42b by a plurality of bolts 62.

  Each of the reflecting plates 61 detects the presence or absence of the cold foil C with a retroreflective photoelectric sensor 65 in which a projector and a light receiver are integrated (film entrainment detection device). As shown in FIGS. 9 and 10, the photoelectric sensor 65 is mounted on a stay 66 that is installed between the left and right frames of the apparatus via a plate-like support member 67. In the illustrated example, ten photoelectric sensors 65 corresponding to the ten reflecting plates 61 are attached by bolts 69 via U-shaped brackets 68 in the trunk axis direction. In the figure, reference numeral 71 denotes a protective cover bolted to the support member 67.

  As shown in FIG. 11, each photoelectric sensor 65 has its detection signal input to a control device 73 together with a main phase detector 72 such as a rotary encoder. The control device 73 drives and controls the machine motor 74 according to the operation flow shown in FIG. 12 based on detection signals from the photoelectric sensors 65 and the machine phase detector 72.

  In other words, when the phase of the main unit reaches a predetermined transfer in step P1, it is determined in step P2 whether any one of the photoelectric sensors 65 is 0FF. Here, when there is no cold foil C (when the cold foil is not detected), the reflected light is input and the photoelectric sensor 65 becomes 0N, and when there is the cold foil C (when the cold foil C is detected), the reflected light is blocked. The photoelectric sensor 65 is set to 0FF.

  If yes in step P2, the driving of the motor 74 is stopped in step P3. If no, the process returns to step P1, and this is repeated thereafter.

  Due to such a configuration, the plurality of cold foils C unwound from the unwinding shaft 18 pass through the guide roller 22 and then the first dancer roller portion 24 and the second dancer disposed on the downstream side thereof. The reel tension adjusting mechanism 27 including the dancer roller portion 26 absorbs the inherent tension fluctuation in the cold foil C of each winding.

  The tension-adjusted multiple-winding cold foil C is pulled by a pair of pinch rollers 28, passes through the feeding side of the transfer tension adjusting mechanism 30, passes between the impression cylinder 12 and the rubber cylinder 16, and is a sheet. The foil (aluminum deposition layer) of the cold foil is transferred to the area of the paper P where the adhesive has been applied in advance, and the transferred cold foil C is now transferred to the recovery side of the transfer tension adjusting mechanism 30 together with the base film. After passing, it is pulled by the pair of pinch rollers 31 and taken up by the take-up shaft 21 through the guide roller 32 as described above.

  In the present embodiment, when the cold foil C passes through the cutout portion 15 of the rubber cylinder 16, it is guided to the guiding peripheral surface portion 42 a of the gap cover 42. The guide peripheral surface portion 42a has substantially the same curvature as the press peripheral surface portion covered with the blanket B in the rubber cylinder 16, and extends over approximately half the width of the cutout portion 15 (the length in the circumferential direction). Therefore, the tension fluctuation of the cold foil C due to the change in the span length of the cold foil C can be greatly reduced.

  FIG. 13 is a graph showing changes in the film span length (the shortest distance of the film with respect to the center of the rubber cylinder) with and without the gap cover 42 based on the experimental results of the present inventors. In addition, the film span length said here is the span length of the cold foil C of a present Example. As can be seen from this graph, the change in the span length of the cold foil C can be greatly suppressed when the gap cover 42 is present as compared with the conventional case where the gap cover 42 is not present.

  In this manner, the tension fluctuation of the cold foil C due to the change in the span length of the cold foil C can be greatly reduced, so that the cold foil C can be prevented from being damaged and entangled in the rubber cylinder 16 in advance. On the other hand, the interference with the gripper claw devices 10a and 10b of the impression cylinder 12 as in the past is caused by the shielding peripheral surface portion 42b lowered to the inside of the notch 15 from the guiding peripheral surface portion 42a connected to the guiding peripheral surface portion 42a. Avoided.

  In addition, since the surface of the guide peripheral surface portion 42a of the gap cover 42 is subjected to surface processing having unevenness or a flexible material having unevenness is pasted, the peripheral surface portion for guiding the cold foil C by the surface having the unevenness The close contact with 42a is prevented and it becomes slippery, the tension fluctuation is further reduced, and the rubber cylinder 16 is prevented from being caught. Furthermore, if there is flexibility, damage to the cold foil C can be further prevented. These surface treatments are effective when the rubber cylinder 16 is idled while the cold foil C is stopped.

  In this embodiment, if the cold foil C is caught in the rubber cylinder 16, the photoelectric sensor 65 detects this and stops the driving of the machine motor 74, that is, the operation of the sheet-fed printing press. Therefore, adverse effects on the respective parts due to the cold foil C being caught can be avoided in advance. That is, it is possible to prevent the accidental collapse of the rubber cylinder 16 and the risk of sudden production stoppage. At this time, it is preferable to stop the driving of the machine motor 74 and simultaneously activate an alarm device or a display device so as to notify the operator of the cold foil C being caught.

  Further, since the photoelectric sensor 65 is disposed on the stay 66 installed above one side of the rubber cylinder 16, there is an advantage that the dust does not collect and does not interfere with the work. In addition, since ten photoelectric sensors 65 and reflectors 61 are arranged at predetermined intervals in the cylinder axis direction of the rubber cylinder 16, no matter which position the narrow cold foil C flows through, any one of them is always provided. If the photoelectric sensor 65 is on the travel route of the cold foil C, it can be detected. Further, since the photoelectric sensor 65 is a retroreflective type, the film C in any state such as having a metallic luster, being transparent, or wrinkled can be detected correctly.

  It should be noted that the present invention is not limited to the above-described embodiment, and various changes such as a change in the structure and shape of the gap cover and a change in the structure and quantity of the photoelectric sensor can be made without departing from the scope of the present invention. Absent. Further, the present invention applies a resin varnish to the printing surface to give gloss, and presses the transfer film from above to transfer the pattern of the transfer film having a hologram pattern to process the printing surface The present invention can also be applied to a film handling apparatus that can perform (Patent Document 4). Furthermore, the present invention uses a pressing surface provided on the outer peripheral surface so as to heat a stamping die having a pattern formed thereon, and presses the transfer foil having an adhesive layer against the sheet-like material. The present invention can also be applied to hot foil transfer (hot foil stamp) in which a foil is transferred to a sheet-like material via an adhesive layer (Patent Document 5).

  In the film handling apparatus according to the present invention, since the cover is effectively arranged in the notch portion of the pressing cylinder, it is possible to greatly reduce the film tension fluctuation and prevent the film from being damaged. In addition to the cold foil transfer apparatus, it can be used extremely beneficially in various industries.
