A movable chuck 8 disposed at a distant position and capable of moving back and forth in the long side direction of the tape moves in the vicinity of the fixed chuck 6.

  That is, the feed chuck 1 and the movable chuck 8 that are sandwiched with the tip end of the tape A exposed, move to the left and right sides in the vicinity of the fixed chuck 6. At this time, the upper and lower claws 6a, 6b, 8a, and 8b of the fixed chuck 6 and the movable chuck 8 are expanded upward and downward, and the tip of the tape A does not obstruct the fixed chuck 6 and the movable chuck 8 The upper and lower claws 8a and 8b can be sandwiched.

  The movable chuck 8 sandwiching the tape A moves in a direction away from the fixed chuck 6, and the feed chuck 1 returns to the tape reel side, and then the tape A is sandwiched by the fixed chuck 6.

  The tape A sandwiched between the fixed chuck 6 and the movable chuck 8 is cut by a cutter disposed on the tape reel side in the vicinity of the fixed chuck 6, and then the claws 6 a on the upper side of the fixed chuck 6 and the movable chuck 8. 8a is rotated inward and moved to a position directly above the fluorescent tube B by another mechanism. Then, the tape A is pressed against the side surface of the fluorescent tube B, and the upper and lower claws 6a and 6b of the fixed chuck 6 and the movable chuck 8 are moved. , 8a, 8b, the tape A can be adhered to the fluorescent tube B.

  In addition, for example, Patent Document 2 discloses a technique in which the disposable chopsticks 42 are attached to the side surface of the packed lunch box 40 with the tape T, and according to the present technology, the adhesive is attached to one side fed from the wound tape reel. The strip-shaped tape T having a layer is fed out by the roller guide portion 10, and a tape pulling mechanism 28 that can move forward and backward toward the tape T in the long side direction of the tape T moves to the vicinity of the roller guide portion 10, so that the tape pulling mechanism 28 The predetermined length for cutting out is ensured by separating with the two claws 32 and 34 being separated from the front end of the tape T.

  Thereafter, the tape T is cut by the cutter 18 disposed in the vicinity of the roller guide portion 10 while the two transport rollers 22 and 24 formed in the tape transport mechanism 20 are urged from the adhesive side of the tape T, and the tape T After the two claws 32, 34 of the drawer mechanism 28 are opened, the split chopsticks 42 are fixed to the folding lunch box 40 by the tape transport mechanism 20 with respect to the split chopsticks 42 placed on the side surface of the folding lunch box 40.

[Thin object-like gripping mechanism]
As shown in FIGS. 1A, 1B, 6A, and 6B, the thin object copying and gripping mechanism 1 according to the embodiment of the present invention includes a sandwiching portion 2 and a base portion 44. A gripping mechanism for uniformly sandwiching a film-like thin object T from the front and back surfaces by the sandwiching part 2, wherein the sandwiching part 2 includes a first claw part 3 and a pair of first claw parts 3 facing each other when the thin object T is sandwiched And the base 44 includes a drive mechanism 45 that allows at least one of the first claw 3 and the second claw 31 to be movable. The base 44 side is the connection end 27, the distal end side 6 is the open end 28, and the first claw portion 3 has a scanning seat surface 19 that moves in a pendulum shape by the rotating shaft 20 and abuts against the thin object T. By providing the copying rotation piece 18, the first and second claw portions 3 and 31 follow the contact surface 40 of the second claw portion 31 so that the copying seat surface 19 follows the abutment surface 40 of the thin object T. It is configured to be freely contact abutting a more thin-shaped material T.

  Further, the copying seat surface 19 and / or the contact surface 40 is configured so that the thin object T sandwiched and opened by performing an adhesion preventing process can be easily discharged from the first claw portion 3 and the second claw portion 31. Yes.

  Further, the first and second claw portions 3 and 31 are arranged to face each other substantially in parallel, and at least one of the first and second claw portions 3 and 31 can be moved toward and away from the drive mechanism 45 while remaining substantially parallel. doing.

  Specifically, the first claw portion 3 constituting the clamping portion 2 is disposed with the copying seat surface 19 facing upward, and the second claw portion 31 is directed above the first claw portion 3 with the contact surface 40 facing downward. And are arranged opposite to each other substantially in parallel.

  Further, as shown in FIG. 5 (a), the drive mechanism 45 included in the base 44 is a link mechanism or the like that is linked with piston movement by an air cylinder 48 that uses compressed air or electricity as a power source or rotation by a motor. The first and second claw portions 3, 31 are configured such that the copying seat surface 19 and the contact surface 40 can be brought close to and away from each other by the drive mechanism 45.

  Hereinafter, each part will be specifically described in detail.

  As shown in FIGS. 1 to 3, the first claw portion 3 is formed of a substantially T-shaped rectangular block body having two female screw holes 5 and slidably connected to the base portion 44 by a slide bearing or the like. The first convex piece 4 and the first claw piece 7 which surrounds and fits the front part of the first convex piece 4 from below.

  The first claw piece 7 is formed by a substantially L-shaped rectangular block in plan view extending forward from the first convex piece 4 that is the connection end 27 on the base 44 side, and the fitting portion with the first convex piece 4 Is formed as a first fitting recess 8 with two bolt holes 9 formed at the bottom, and the tip side 6 is formed with a rotating piece storage portion 10 cut in a substantially L shape in side view, In the rotating piece storage portion 10, the copying turning piece 18 is disposed so that the upper portion of the copying turning piece 18 on which the copying seat surface 19 is formed protrudes.

  Also, the first convex piece 4 and the first claw piece 7 are screwed into a bolt hole 9 and a female screw hole 5 formed so as to be in communication with each other when fitted, and a bolt 17 is screwed from below to form an integrated first claw portion. 3 is formed. In this way, a strong connection can be made by fastening the front portion of the first convex piece 4 with the bolt 17 while fitting and surrounding the first fitting concave portion 8 from above.

  The copying rotation piece 18 is formed in a rectangular shape with the upper surface serving as a copying seat surface 19, and a rotation shaft 20 that is erected vertically from the lower surface of one side surface orthogonal to the copying seat surface 19 is integrally formed. doing. Further, an engaging groove 21 for engaging a first claw piece 7 and a C ring 22 that can be freely fitted and connected is formed in the vicinity of the tip of the rotating shaft 20.

  The copying seat surface 19 needs to be smooth, but in use in which a load is applied to the thin object T, a plurality of substantially uniform fine irregularities are formed to increase the frictional force at the time of clamping. desirable.

  Further, an adhesion preventing process is applied to the upper portion of the copying rotation piece 18, at least the copying seat surface 19. The anti-adhesion treatment is, for example, a surface modification performed by treatment with TOSICAL (registered trademark of Tokyo Silicone Co., Ltd.) or fluorine coating. The adhesion of the pressure-sensitive adhesive to 18 and the peelability of the thin object T when released are improved.

  In addition, chamfering is performed on the lower end corner portions 23 of the two portions of the copying rotation piece 18 so as to avoid contact with the side wall 15 and the bottom portion 16 of the rotation piece storage portion 10.

  The rotating piece storage portion 10 is formed by a vertical wall 11, a side wall 15, and a bottom portion 16, and a tapered portion 12 is formed outside the vertical wall 11.

  A shaft hole 13 and a sliding avoidance portion 14 are formed in the vertical wall 11, and the shaft hole 13 is formed in a direction orthogonal to the vertical wall 11 so that the copying seating surface 19 faces upward. The rotating shaft 20 is inserted.

  The inner diameter of the shaft hole 13 is not limited to the outer diameter of the rotating shaft 20 and can be made as small as possible, so that the backlash of the copying rotating piece 18 can be minimized, and the rotating shaft 20 is erected. By forming the distance from one side surface of the copying rotation piece 18 to the engagement groove 21 as short as possible without being limited by the thickness of the vertical wall 11, the play of the copying rotation piece 18 can be minimized.

  Further, if the distance from the upper surface of the vertical wall 11 to the copying seat surface 19, that is, the distance from the upper surface of the vertical wall 11 to the copying seat surface 19 is shortened, the backlash of the copying rotating piece 18 can be suppressed. it can. However, in the case where the thin object T to be sandwiched has an adhesive layer on one side, the adhesive surface can easily contact not only the copying seat surface 19 but also the vertical wall 11, and the adhesive adheres to the vertical wall 11. Therefore, the distance is desirably set appropriately and flexibly according to the thin object T to be sandwiched.

  The sliding avoiding portion 14 is formed by cutting the upper side of the shaft hole 13 inside the vertical wall 11 so that a gap is formed between the side surface of the copying rotating piece 18 and the vertical wall 11. Friction due to contact between the rotating piece 18 and the vertical wall 11 can be reduced, and the copying turning piece 18 can be smoothly rotated.

  In addition, when the thin object T to be sandwiched has an adhesive layer on one side surface, not only can the contact of the adhesive surface with the vertical wall 11 be suppressed, but also the adhesive adhered to the copying seat surface 19. It is possible to prevent deposits from increasing as the agent wraps around the gap between the side surface of the copying and rotating piece 18 and the vertical wall 11 and hindering the rotation of the copying and rotating piece 18 by the deposit.

  Further, the tapered portion 12 formed by chamfering the outside of the vertical wall 11 indicates that the adhesive surface is in contact with the vertical wall 11 when the thin object T to be sandwiched has an adhesive layer on one side surface. Can be prevented. The taper portion 12 can be subjected to the above-described adhesion preventing process.

  Further, the movable range of the copying rotation piece 18 is restricted by the contact between the bottom surface 24 and the lower end corner 23 of the copying rotation piece 18 and the bottom 16 of the rotation piece storage unit 10 and the side wall 15. The gap distance may be set as appropriate depending on the material, shape, size and thickness of the thin object T to be sandwiched, and the performance of the apparatus used.

  Next, like the first claw portion 3, the second claw portion 31 is a substantially T-shaped rectangular block body having two female screw holes 33 and slidably connected to the base portion 44 by a slide bearing or the like. The formed second convex piece 32 and the second claw piece 35 that surrounds and fits the front portion of the second convex piece 32 from above are configured.

  The second claw piece 35 has a substantially L shape in plan view extending forward from the second convex piece 32 which is the connection end 27 on the base 44 side, and is viewed from the horizontal direction in a front view and is a substantially T-shaped first half. The fitting part with the 2nd convex piece 32 is formed in a concave shape, and the bolt hole 37 of two places is drilled as the 2nd fitting recessed part 36 at the upper part.

  The second convex piece 32 and the second claw piece 35 are screwed into a bolt hole 37 and a female screw hole 33 formed so as to be in communication with each other at the time of fitting, and the second claw piece 31 is integrated with the bolt 41 from above. Form. Thus, a firm connection can be achieved by fastening the front portion of the second convex piece 32 to the second fitting concave portion 36 from below and fastening it with the bolt 41 while surrounding it.

  Further, a piece that hangs down in the vertical direction of the front half 34 that is substantially T-shaped is used as a separation preventing piece 38, and the separation preventing piece 38 moves toward the base 44 side of the thin object T when the thin object T is sandwiched. Prevent movement.

  Further, a piece extending in the horizontal direction of the front half portion 34 having a substantially T-shape is used as a contact piece 39, the contact piece 39 is formed with a lower surface as a contact surface 40, and the contact surface 40 is a first nail. When the thin object T is sandwiched between the copying seat surface 19 formed on the copying rotation piece 18 of the portion 3, it comes into contact with the surface of the thin object T.

  The abutment surface 40 needs to be smooth, but in use where a load is applied to the thin object T, a plurality of substantially uniform fine irregularities are formed to increase the frictional force during clamping. desirable.

  Further, the lower part of the contact piece 39, at least the contact surface 40, is subjected to an adhesion preventing process. The adhesion preventing process is as described above.

  In this case, even if the adhesive surface of the thin object T is on the lower side where it does not come into direct contact with the contact surface 40, the adhesive that slightly protrudes from the side end of the thin object T to the contact surface 40 Adhesion and accumulation can be prevented.

  As described above, the clamping part 2 including the first and second claw parts 3 and 31 is configured.

  In the present embodiment, only one vertical wall 11 is formed in the rotating piece storage unit 10, but two vertical walls 11 are arranged opposite to each other, and the rotating shaft 20 of the copying rotating piece 18 is also formed. You may comprise so that the rotation axis | shaft 20 may be inserted in the shaft hole 13 formed in the both sides | surfaces and drilled in the mutual perpendicular | vertical wall 11. FIG. In other words, it is possible to enhance the loose fitting and fixing of the copying and rotating piece 18 by sandwiching the copying and rotating piece 18 between the two vertical walls 11.

  Further, in loose fitting and fixing of the copying rotation piece 18 to the vertical wall 11, the rotation shaft 20 is not formed integrally with the copying rotation piece 18, but a shaft hole is formed in the copying rotation piece 18. Alternatively, a separate rotation shaft may be inserted through the shaft hole 13 of the vertical wall 11.

  Furthermore, the axial direction of the rotating shaft 20 is not limited to the present embodiment, and, for example, as shown in FIGS. 4A and 4B, depending on the type and shape of the thin object to be sandwiched, the moving direction, and the like. As shown, the rotation shaft 20 may be formed in the extending direction of the first claw portion 3, and in this case, for example, when the tip end portion of the strip-shaped thin object T is held from the longitudinal direction and pulled out. In addition, it is possible to hold the thin object T with a substantially uniform pressure over the entire holding area of the thin object T.

  As shown in FIG. 5 (a), the base 44 includes an air cylinder 48 provided with an intake port 46 and an exhaust port 47, and one end loosely fitted to the tip of a piston 49, and the other is connected to the first convex piece 4 and the second convex portion. The drive mechanism 45 is constituted by the link stays 50, 50 loosely fitted on the piece 32, and in this embodiment, the compressed air is supplied to the air cylinder 48 so that the piston 49 moves backward and exhausts to operate. A cylinder 48 is used.

  Accordingly, when the compressed air is supplied from the intake port 46 of the air cylinder 48, the piston 49 moves backward, and the first convex piece 4 and the second convex piece 32 are slidable in the vertical direction via the link stays 50, 50. Close to each other by slide bearings.

  Further, the compressed air is discharged from the exhaust port 47 of the air cylinder 48 so that the piston 49 advances, and the first convex piece 4 and the second convex piece 32 are separated from each other via the link stays 50 and 50.

  By configuring the base 44 in this way, the thin object T can be sandwiched or released by the first and second claw portions 3 and 31.

  In the present embodiment, the drive mechanism 45 of the base 44 controls the operation of clamping and opening the first and second claw portions 3 and 31 by compressed air, but the drive mechanism 45 is limited to this embodiment. For example, the air cylinder 48 described above may be replaced with an electromagnetic solenoid, and the portion corresponding to the piston 49 may be moved forward and backward to bring the first convex piece 4 and the second convex piece 32 closer to or away from each other.

  Further, for example, as shown in FIGS. 5B and 5C, the first convex piece 4 and the second convex piece are screwed into the peripheral side surface of the drive shaft 52 of the motor 51 connected to the electric wiring 54. Each of the rear ends of 32 is threaded with a screw thread that engages with the drive shaft 52 and is provided with a support shaft 53 in the direction of the paper surface. The piece 32 may be configured such that the first and second claw portions 3 and 31 are sandwiched and opened by controlling the approach and separation around the support shaft 53.

  As described above, the driving mechanism 45 of the base portion 44 can be any mechanism that allows the first and second claw portions 3 and 31 to be sandwiched and opened, and various configurations can be used within the scope of the present invention. it can.

  The thin object copying and gripping mechanism 1 configured as described above holds the thin object T between the first and second claw portions 3 and 31 as shown in FIGS. 6 (a) to 6 (c). When the scanning rotation piece 18 rotates following the contact surface 40 of the thin object T and the second claw portion 31, the thin object T can be applied with a substantially uniform pressure over the entire sandwiched area of the thin object T. Can be held.

  Here, as shown in FIGS. 7A to 7D, in the case of the gripping mechanism 56 that does not have the copying rotation piece 18, the first claw portion 57 and the second claw portion 31 are made parallel by mechanical adjustment. Even if they are brought into close contact with each other (FIGS. 7A and 7B), since the thin object T is repeatedly sandwiched and released, the pressure sandwiched closer to the base 44 side is concentrated over time ( 7 (d), for example, as shown in FIGS. 8 (a) and 8 (b), when the belt-like thin object T is sandwiched and moved, the thin object Ta is twisted starting from the pressure concentration point 58. .

  However, if the thin object copying and gripping mechanism 1 provided with the copying rotating piece 18 is used, the thin object T can be held with a substantially uniform pressure over the entire holding area of the thin object T. The object T can be pulled out linearly without being twisted.

  In the present embodiment, the first claw portion 3 is disposed below the second claw portion 31, but is not limited to this, for example, as shown in FIGS. 9A and 9B. It may be configured upside down, and various configurations can be used depending on the type and shape of the object to be clamped.

  In the present embodiment, both the first and second claw portions 3 and 31 are movable. However, the present invention is not limited to this. For example, one may be fixed and the other may be movable. .

  As described above, the thin object copying and gripping mechanism 1 according to the present embodiment is configured, and the sandwiching portion 2 includes the pair of first claw portions 3 and the second opposing claws when the thin object T is sandwiched. The claw portion 31, and the base portion 44 includes a drive mechanism 45 that allows at least one of the first claw portion 3 and the second claw portion 31 to be movable. The first and second claw portions 3, 31 are each a base portion. The first claw portion 3 has a scanning seat surface 19 that is movable in a pendulum shape by the rotary shaft 20 and abuts against the thin object T. By providing the rotating piece 18, when the thin object T is sandwiched, the copying seat surface 19 follows the contact surface 40 of the second claw part 31 and the first and second claw parts 3, 31 reduce the thin object. Since the thin object T can be clamped with uniform pressure by being configured to be in close contact with the T, the thin object T can be moved while being clamped. Ri can be under load thin like material T, nipped thin like material T is reliably clamped without kinking between the abutment surface 40 and the copying seat 19.

  Further, the copy seating surface 19 and / or the contact surface 40 is configured so that the thin object T sandwiched and opened by performing an adhesion preventing process can be easily discharged from the first claw portion 3 and the second claw portion 31. As a result, even when the plurality of thin objects T are continuously sandwiched and released a plurality of times, the clamping accuracy and the opening accuracy can be maintained uniformly for a long time.

  In particular, in the case of a thin object T having an adhesive surface on one side, adhesion of the adhesive material to the copying seat surface 19 and the contact surface 40 can be prevented. The maintenance frequency of the thin object copy gripping mechanism 1 can be minimized.

  Further, the first and second claw portions 3 and 31 are arranged to face each other substantially in parallel, and at least one of the first and second claw portions 3 and 31 can be moved toward and away from the drive mechanism 45 while remaining substantially parallel. As a result, when the thin object T is sandwiched, the entire clamping surface of the thin object T can be clamped almost simultaneously, so that the thin object T is twisted between the contact surface 40 and the copying seat surface 19. Can be prevented.

  Next, the thin object feeding and cutting device 101 including the above-described thin object copying and gripping mechanism 1 according to the embodiment of the present invention will be described.

The thin object copying and gripping mechanisms 1a and 1b are configured to be freely movable in any direction. However, the moving mechanism 104 is not limited to the present embodiment. For example, the moving mechanism 104 such as a slide bearing is fed. Within the scope of the gist of the present invention, it is arranged on the stable upper end surface of the device 102, and the thin object copying and gripping mechanisms 1a and 1b are connected to the device 102 so that the stay is omitted and the backlash is reduced.

Specifically, A suction transfer portion 115 is disposed on one end side of the arm portion 111 extending in the horizontal direction, and is connected to a motor shaft 112 of a motor having an axial center vertically above the other end portion side.

  With this configuration, the thin object T is placed in the product P or the box placed on the work table S by the rotation of the motor shaft 112 while the cut thin object T is adsorbed by the adsorption unit 118. Can be attached or accommodated.

  The driving method and configuration of the feeding device 102 and the transfer device 110 are not limited to this embodiment, and various modifications and changes can be made within the scope of the gist of the present invention.

  Hereinafter, the operation of the thin object feeding and cutting device 101 will be described.

  FIG. 11A is a front view of the main part of the thin object feeding and cutting device 101, and FIG. 11B is a pair of thin object copying and gripping mechanisms 1a and 1b and their surroundings. The thin object copying and gripping mechanisms 1a and 1b are arranged to face each other via the thin object T, and one thin object copying and holding mechanism 1a holds the end of the thin object T and the other 1b. Sandwiches the middle part of the thin object T.

  The main body 116 of the adsorption transfer unit 115 descends with respect to the thin object T sandwiched between the pair of thin object copying and gripping mechanisms 1a and 1b, and the thin object T is adsorbed by the adsorption unit 118 of the main body 116. .

  Further, the cutter blade 107 constituting the cutting portion 106 is disposed in the vicinity of the other thin object copying and gripping mechanism 1b, and specifically, disposed below the thin object T and behind the thin object T. Then, the cutting part 106 is raised, and the sandwiched thin object T is cut from the back side to the near side and then returned to a predetermined position.

  The cut thin object T is transferred to a predetermined location by the suction transfer unit 115 as the main body 116 is raised.

  The thin object feeding and cutting device 101 according to the present embodiment can send out and cut out the thin object T continuously by alternately changing the position of the pair of thin object copying and gripping mechanisms 1a and 1b in the above-described operation. It can be done.

  Such an operation will be described in more detail with reference to FIGS. 12A to 12G showing a continuous operation in plan view.

  First, as shown in FIG. 12A, the other thin object copying and gripping mechanism 1b moves forward (A) so as not to interfere with one thin object copying and holding mechanism 1a, and then the thin object T One thin object copying and gripping mechanism 1a sandwiching is moved to the right (B), and at the same time, the other thin object copying and holding mechanism 1b is moved to the left (C).

  Next, as shown in FIGS. 12B and 12C, the other thin object copying and gripping mechanism 1b moves (D) to the thin object T side on the back side, and the middle part of the thin object T is moved. Hold it.

  Thereafter, the hatched portion K shown in FIG. 12 (d) is adsorbed from above by the body portion 116 (not shown), and then the cutting portion 106 is raised and sandwiched as shown in FIG. 12 (e). As shown in FIG. 12 (f), the thin object T is gripped by one thin object, as shown in FIG. 12 (f). The mechanism 1a releases the thin object T, and the main body 116 (not shown) rises while adsorbing the cut thin object T, and is transferred to a predetermined location by the adsorption transfer unit 115.

  Thereafter, as shown in FIG. 12 (g), one thin object copying and gripping mechanism 1a moves to the back side so as not to interfere with the other thin object copying and holding mechanism 1b (F), and then the thin object The other thin object copying and gripping mechanism 1b holding T is moved to the right (G), and at the same time, one thin object copying and holding mechanism 1a is moved to the left (H), and the above-described operations are sequentially repeated.

  In this way, it becomes possible to accurately feed and cut out the strip-shaped thin object T, and in particular, the pair of thin object copying and gripping mechanisms 1a and 1b according to the present invention are arranged to face each other via the thin object T. 6 (a) to 6 (c), when the thin object T is sandwiched between the first and second claw portions 3 and 31, the copying rotation piece 18 is separated from the thin object T. By rotating following the contact surface 40 of the second claw portion 31, it is possible to hold the thin object T with a substantially uniform pressure over the entire holding area of the thin object T, as shown in FIGS. 13 (a) and 13 (b). As described above, a plurality of thin objects T can be linearly cut out continuously (t) as an accurate rectangular shape.

  Here, in the case where the thin object feeding and cutting device 101 is configured using the gripping mechanism 56 that does not have the copying rotating piece 18, as shown in FIGS. Even if the claw portion 57 and the second claw portion 31 are in close contact with each other in parallel, as shown in FIG. For example, when the belt-like thin object T is sandwiched and moved as shown in FIGS. 8A and 8B, the thin object Ta starts from the pressure concentration point 58, for example. Will twist.

  In this case, when the gripping mechanism 56 that does not have the copying rotation piece 18 is disposed to face the belt, the belt-like thin object T is splayed as shown in the image diagram (plan view of the thin object T) shown in FIG. As shown in FIG. 14 (b), the thin object T to be cut out is trapezoidal.

  In addition, when the pair of thin object copying and gripping mechanisms 1a and 1b are not disposed to face each other and are disposed only on one side of the thin object T, as shown in FIG. Since it is sequentially sent and cut out so as to draw an arc (t), as shown in FIG. 15B, the shape of the thin object T to be cut out becomes a parallelogram.

  Next, a thin object feed cutting device 121 according to a modification of the present embodiment will be briefly described.

  As shown in FIG. 16, the thin object feeding and cutting device 121 according to the modified example has a pair of thin object copying and gripping mechanisms 1 disposed on one side in the longitudinal direction of the thin object T. The configuration is the same as that of the thin object feeding and cutting device 101 described above.

  FIG. 17A is a front view of the main part of a thin object feed cutting device 121 according to a modification, and FIGS. 17B and 17C are a pair of thin object copying devices of the thin object feed cutting device 121. FIG. 2 is a plan view of the gripping mechanism 1 and its periphery, and the two thin object copying and gripping mechanisms 1 a and 1 b are disposed on the back side of the thin object T, and one thin object copying and gripping mechanism 1 a is the thin object T. The other end 1b sandwiches the middle part of the thin object T.

  One thin object copying and holding mechanism 1a is movable in the order of a → b → c → d → e → f, and the other thin object copying and holding mechanism 1b is u → v → w → x → w → z. It is movable in the order.

  That is, one thin object copying and gripping mechanism 1a moves (a) to the right along the longitudinal direction while holding the thin object T and maintaining the horizontal direction, and after the thin object T is cut out, Then, it is held open and moved further back (b).

  Then, it moves upward (c), and further moves to the left (d) as it is, then descends (e) and then moves forward (f) to sandwich the thin object T again.

  In addition, the other thin object copying and gripping mechanism 1b is configured such that after the thin object T is cut out, it is nipped and released and moved to the back side (u), and then moved downward (v) and further leftward as it is. Move (w).

  After that, after rising (x) and moving (y) to the front, the thin object T is held again, and after the thin object T is cut out, the horizontal direction is maintained while holding the thin object T. Move (z) to the right along the longitudinal direction.

  In this case, the position where the thin object T is sandwiched between the two thin object scanning gripping mechanisms 1a moves to the right (a), and the other thin object scanning gripping mechanism 1b moves forward (y ), Or when the other thin object copy gripping mechanism 1b is moved to the right (z), the one thin object copy gripping mechanism 1a is moved forward (f). It is.

  Accordingly, since the position of the thin object T to be cut out is always two places, the cutting portions 106 are also arranged at two places accordingly. Furthermore, the suction position of the thin object T by the suction transfer unit 115 also operates at a position following this.

  The thin object feeding and cutting device 121 according to the modification is configured as described above. However, as long as the pair of thin object copying and holding mechanisms 1a and 1b do not interfere with each other, the two thin object copying and holding mechanisms 1a and 1b are provided. In this case, only one cutting unit 106 is sufficient, and the suction position of the thin object T by the suction transfer unit 115 can be operated at the same position.

  As described above, the thin material feeding and cutting devices 101 and 121 according to the present embodiment are configured, and are sequentially cut and moved from the tip while feeding the strip-shaped thin material T having one side as an adhesive surface. A thin object feeding and cutting device 101, 121 comprising a pair of thin object copying and gripping mechanisms 1a, 1b, a cutting unit 106, and a suction transfer unit 115, and the thin object copying and holding mechanisms 1a, 1b. Has a rotating shaft 20 in the longitudinal direction of the thin object T, and is arranged with the open end 28 facing the short direction of the thin object T, and advances and retreats in the longitudinal direction and the short direction of the thin object T. The thin object copying and gripping mechanisms 1a and 1b are configured to be movable alternately with respect to the longitudinal direction of the thin object T. When one side 1a clamps the tip of the thin object T and the other side 1b clamps the midway part, 2 Between the thin object copying and gripping mechanisms 1a and 1b and in the vicinity of the other thin object copying and gripping mechanism 1b. The suction transfer unit 115 has a suction part 118 on the front end surface 117 of the main body 116. And the other side surface of the thin object T is configured to be vacuum-suckable by the suction part 118, and the main body part 116 is configured to be at least close to and away from the thin object T. Since the thin object T can be sandwiched with a substantially uniform pressure, the thin object T can be moved even when the thin object T is moved or when the thin object T is subjected to a load. It is possible to securely hold the contact surface 40 and the copying seat surface 19 without twisting.

  Further, since the pair of thin object copying and gripping mechanisms 1 can continuously operate while changing the position alternately without performing the holding operation of the thin object T, the thin object T can be sent out and cut out efficiently.

  Further, in the thin object feeding and cutting device 101, the thin object copying and gripping mechanisms 1a and 1b are opposed to each other via the thin object T, so that the sandwiched thin object T is in contact with the contact surface 40. Even if the copy seat surface 19 is slightly twisted, the outer shape error of the thin object T cut out without being biased in one direction can be minimized.

  Further, in the thin object feeding and cutting device 101, the thin object copying and gripping mechanisms 1a and 1b are arranged opposite to each other via the thin object T, so that the thin object copying and gripping mechanisms 1a and 1b are disposed to each other. Since each of the moving mechanisms 104 is also separated, the maintainability can be improved.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. It can be changed.
