Thereby, the packing operation of the long material wound around the winding frame can be automated, and the efficiency and rationalization of the packing operation of the long material can be achieved.

  The bending mechanism of the present invention can be constituted by a rotating bending means and a bending maintaining means. Along with the bending operation of the rotating bending means, the pair of flange portions can be folded inward so that the ends of each of the flange portions abut or overlap each other. The folding posture of the flange portion folded by the rotating bending means can be maintained by operating the flange portion toward the end surface of each flange portion in the folded state. Thereby, the folding operation | work of the said flange part and the maintenance operation | work of a folding form can be performed continuously and efficiently.

  The operation by the turning bending means and the bending maintaining means can be performed by the same member or by separate members. In the case where the same member is used for turning and maintaining the bending, the flange can be folded by the member and then the flange can be folded to maintain the member. . When rotating bending and bending maintenance are performed by separate members, the flange portion is folded by one member and then pressed between the ends of the pair of flange portions by the other member. The folded state of can be maintained.

  As said rotation bending means, it can be comprised by a rotation member and a bending member. By turning the turning member, the bending member extended along the turning shaft of the turning member can be turned in the same direction as the folding direction of the flange member. The bending member rotates around the rotation axis of the rotating member, and the bending member is rotated toward the end surface of the flange portion, so that the flange member is quickly and reliably folded. be able to.

  As the bending mechanism, the rotating bending means and the bending maintaining means can be configured by separate members so as to operate independently, but both may be integrated. As the bending maintenance means configured separately from the rotating bending means, for example, a pressing member that can press and support the surface of the flange portion folded by the rotating bending means can be used. Can do. After the flange portion is folded by the rotating bending means, the pressing operation to the surface of the flange portion can be performed by the pressing member. After the flange member surface is pressed by the pressing member, the rotating and bending means can be retracted from the flange portion surface.

  Furthermore, a folding position adjusting means can be provided in the folding mechanism. Even if the winding diameter of the long material wound around the circumferential surface of the winding frame differs depending on the winding form and winding amount of the long material by the winding device, the assembly shape of the winding frame, etc., the winding diameter of the long material Accordingly, the height position at which the flange portion is folded can be adjusted. The rotation bending means can be positioned at a desired height position by the folding position adjusting means, and the folding operation of the flange portion can be performed. Thereby, it becomes possible to arbitrarily select the folding height position of the flange portion by the rotating folding means, and the folding position of the flange portion can be set, for example, from the winding peripheral surface of the winding frame. It can be reliably folded and folded at a position corresponding to the winding diameter.

  Further, the folding position adjusting means can adjust the folding position of the flange portion to an optimum folding position, and prevents the flange portion from being folded so as to cause a defective deformation. be able to. Thereby, the edge parts of each flange part can be reliably stuck now with the whole sticking surface of a sticking tape, and the sticking retention strength of a sticking tape can be raised. Moreover, the sticking position and sticking form of a sticking tape can be stuck to a reel in the position and form which do not impair the external appearance of a package with a sticking tape.

  Since the folding position of the flange portion can be adjusted by the folding position adjusting means, one winding frame is used for various long materials having different thicknesses, widths, and the like. It can be used as a common winding frame and packaging frame. Furthermore, it becomes possible to easily cope with a case where the winding diameter of these long materials is changed. Thereby, automation of packing work can be achieved easily.

  Each means such as the turning bending means, the bending maintaining means, and the folding position adjusting means can be integrated and configured integrally. By integrally configuring in this way, it is possible to achieve downsizing of the bending mechanism, and it is possible to reduce the installation space of the entire apparatus.

  As a coupling mechanism for coupling the ends of the flange portions folded by the folding mechanism of the present invention to each other, a configuration using a tape adhering means can be used. By the tape adhering means, the adhering tape is adhered in a substantially L shape from the surface of at least one end of the flange portion to the side surface beyond the folded ridge line portion of the other flange portion that is folded oppositely. can do. After folding both flange portions so that the end surface of one flange portion overlaps the end surface of the other flange portion, the end surface of one flange portion passes through the end surface of the other flange portion. By sticking the sticking tape to the side surface beyond the bent ridge line part of the other flange part, the sticking strength by the sticking tape can be increased.

  That is, by sticking the sticking tape in a substantially L shape, for example, due to the restoring force of the flanges, the ends of the flanges are lifted, and the flanges are spread outward and spread between the flanges. A force acts to try to peel off the adhesive tape. However, since the adhesive tape is attached in a substantially L shape from the surface of at least one end portion of the flange portion to the side surface beyond the bent ridge line portion of the other flange portion, the adhesive tape is attached. The holding strength can be greatly increased. Thereby, it can prevent that a sticking tape peels.

  As said tape sticking means, it can be set as the structure provided with the sticking pusher and the side surface sticking plate. At this time, it can also be set as the structure which integrated the sticking pusher and the side sticking plate. While the non-sticking surface of the sticking tape is detachably held by the sticking pusher, the sticking tape held by pressing the end of the flange part can be stuck.

  After the sticking pusher sticks the sticking tape while pressing the end of the flange portion, the side sticking plate can be operated with a time difference from the operation of the sticking pusher. At this time, it is possible to slide the side surface of the winding frame including the bent ridge line portion of the flange portion on at least one side along the same side surface while pressing the side surface inward. Thereby, in the state which is pressing the edge part of the said flange part with the said sticking pusher, along the side surface of a winding frame, bending the sticking tape arrange | positioned along the said side sticking plate in a substantially L shape. Can be attached beautifully. At this time, it is possible to perform an adhesive tape attaching operation while adjusting the form of the reel and the flange portion by the adhesive pusher and the side surface adhesive plate.

  Thus, by providing the said adhesion pusher and the said side surface adhesion plate, the folding form of the said flange part is always hold | maintained to a fixed shape, and the form which hold | maintained can be ensured reliably. For this reason, it becomes possible to reduce the occurrence frequency of the form defect of the reel due to the lack of the sticking length of the sticking tape, etc., and it is possible to obtain a finished product of good quality that always has a stable form It becomes. In addition, it is possible to prevent the collapse of the package during storage and transportation of the finished packaged product. In addition, even when the finished packaging product is deformed into a flat shape in order to reduce the loading space, etc., it is possible to prevent the packed long material from collapsing, and the corrugated cardboard paper constituting the winding frame can be prevented. Breakage can be reliably prevented.

  The bending member of the rotating bending means in the bending mechanism can be constituted by a fork-shaped member. The fork-like member can fold the flange portion by rotation from an appropriate rotation driving means, and maintain the state where the rotation of the fork-like member is stopped, thereby changing the bending posture of the flange portion. Can be maintained. That is, the fork-shaped member can also have a function as the bending maintaining means.

  The configuration of the fork-shaped member is configured such that the sticking pusher can be passed between the forks of the fork-shaped member when the bent position of the flange portion is maintained by the fork-shaped member. Can do. Thereby, the adhesive tape is adhered between the end surfaces of the pair of flange portions by the adhesive pusher while maintaining a state where the end surface of the flange portion folded by the fork-like member is pressed. Can do. Then, between the end surface of the folded flange part can be pressed by the sticking pusher.

  While pressing between the end surface of the flange portion with the sticking pusher, the side sticking plate can be operated independently. By allowing the same side sticking plate to pass between the fork end of the fork-like member and the side face of the winding frame, the sticking tape extending to the side sticking plate side can be bent ridge lines of the flange part. It can be made to adhere along the side surface, bend | folding toward the side surface of the said reel including a part.

  At this time, the shape of the package can be adjusted by pressing the side surface of the winding frame inward by the side surface attaching plate. For this reason, it becomes possible to stick the sticking tape extending from the sticking pusher to the side sticking plate side in a substantially L shape without unevenness. Thus, the folding operation of the flange portion and the connecting operation of the end portions of the folded flange portions can be performed smoothly and continuously.

  When the adhesive tape is attached to the region including the side surface of the winding frame by the side surface adhesive plate, the folded flange portion is also pressed by the fork-shaped member, but at least the side adhesive plate is disposed on the side surface adhesive plate side. The fork-shaped member can be retracted to a position where it does not interfere with the operation of the side surface adhesive plate before the adhesive tape is adhered to the side surface adhesive plate. In this case, it is not always necessary to form a gap between the fork-like member and the side surface of the winding frame for allowing the side surface attaching plate to pass therethrough.

  Furthermore, as said tape sticking means, a damper means can be provided in the said sticking pusher, for example. Thereby, the folded surface of the flange portion can be elastically pressed and supported by the pressing surface of the sticking pusher. At this time, it is prevented that an excessive force acts on the reel, and the shape of the reel is not deformed by the sticking pusher, and it continues in a clean form while maintaining the form at the initial stage of assembly. Can be used.

  The back surface side of the length part which protruded to the said side surface adhesive plate side of the said adhesive tape can also be set as the structure hold | maintained detachably on the surface of the said side surface adhesive plate. In addition, by increasing the strength of the tape substrate of the adhesive tape, the adhesive tape is sequentially attached to the side surface of the reel by the side adhesive plate as a configuration capable of maintaining the state protruding to the side adhesive plate side. It can also be set as the structure to let it go.

  Further, the bending mechanism can be provided with a bending plate. This bending plate can have a function as a contact plate for folding the flange portion, as well as holding the end portion of the long material wound around the winding frame during the folding operation of the flange portion. The bending plate can be constituted by a plate member having a width dimension substantially the same as the dimension between the opposing flange parts, that is, the length of the hollow square body part of the winding frame.

  Inserted between the pair of flange portions before folding the bending plate, and in a state where the bending plate is brought into contact with the winding peripheral surface of the long material, the flange portion disposed opposite to the bending member. Can be folded so that the ends of the two overlap each other. After folding each flange part and operating the sticking pusher to stick between the ends of the folded flange part with sticking tape, or before operating the sticking pusher, the bending plate is paired It can be retracted to a position away from between the flange portions.

  In addition, by providing the bending plate, when the flange portions are folded toward each other toward the winding peripheral surface of the long material, the folded flange portions are supported on a single plane. be able to. As a result, the end portions of the flange portions come into contact with each other to be deformed, the bent ridge portion of the flange portion is deformed into a different shape, and the flange portion is folded or opposed. Occurrence of such a situation that the folding positions of the flange portions are different from each other can be prevented.

  For this reason, the flange portion can be folded straight along the side edge of the bending plate and substantially perpendicular to the central axis of the winding frame. The bent ridge line portion of the flange portion can be folded cleanly and accurately, and the folding accuracy of the flange portion can be stabilized and reliably performed.

  The folding mechanism and the coupling mechanism in the automatic packing machine of the present invention can be disposed in the vicinity of the long material winding device. As a result, the reel mounted on the winding device is intermittently driven with respect to the folding mechanism and the coupling mechanism by intermittent driving in the winding device while the winding frame wound with the long material is mounted on the winding device. Indexing and positioning can be performed.

  Furthermore, by intermittent driving of the winding device, the folding flange portion can be indexed and positioned at the operation position of the folding mechanism and the coupling mechanism, and the flange portions are folded and then the ends of the flange portions are joined together. Can continue. After folding each flange portion, the reel that has been packaged can be removed from the winding device by using a conveying means and the removed reel can be stored in the finished product stocker.

Of the four unit substrates 2,..., 2 that are connected and integrated with each other on the corrugated paper P, the unit substrates 2 at both ends of the corrugated paper P are connected to each other along the second fold line L2. The second bent forming part 30-2 that bends so as to face each other, the end connecting part 30-3 that connects the end connecting pieces 2b protruding from both ends of the unit board 2 at both ends, and the unit boards connected to each other 2 is formed in a cylindrical shape to form a substantially square cylindrical hollow rectangular body A.

  FIG. 3A shows the shape of one piece of corrugated paper P transferred from the mount stocker 21 of the mount supply unit 20 via the transfer path 22. FIG. 3 (b) shows a first fold forming section 30-1 that folds the folded wing piece 3 of the corrugated cardboard paper P. The first fold forming section 30-1 has a folded wing piece. 3, the folding blade piece 3 can be creased by being bent at a predetermined angle along the first fold line L1.

  The 1st bending formation part 30-1 is provided with the some hammer 31, ..., 31 which is a blade piece bending member, as shown in FIG.3 (b). Each hammer 31 is arranged opposite to each bent blade piece 3 of the corrugated paper sheet P transferred along the transfer path 22. In addition, a pair of long support members 32 and 32 are erected in parallel at the lower surface position corresponding to the first folding line L1 of the cardboard paper P in the first folding forming section 30-1. The pair of long support members 32, 32 have a function as a contact plate when the bent blade piece 3 is bent by the hammer 31. The cardboard paper P on each of the long supporting members 32 and 32 is transferred and stopped by a transfer means (not shown).

  The hammer 31 is composed of a bent member bent in an approximately L shape toward the upper end of the long support member 32, and a position corresponding to each bent blade piece 3 in the vicinity of the left and right side edges of the transfer path 22. It is arranged in. It is possible to rotate around a shaft portion parallel to the transfer direction of the corrugated paper P via a hammer rotation means (not shown). A roll member 31a that bends the bent blade piece 3 downward is supported on the rotating tip of the hammer 31 via a pin.

  After temporarily stopping the transfer of the corrugated paper P, the hammers 31 are simultaneously directed toward the end surfaces of the bent blade pieces 3 via hammer rotating means (not shown) as shown in FIG. Rotate downward. Thereby, each folding blade piece 3 can be sequentially bent along the first fold line L1 of the corrugated paper sheet P by a necessary angle to give a crease.

  The roll member 31 a has substantially the same width as that of the single bent blade piece 3. The shape of the roll member 31a is not limited to a shape formed from a single bent blade piece 3 and having a length dimension substantially the same as the width dimension of the bent blade piece 3, It can also be set as the structure which the some roll member 31a contact | abuts with respect to the width dimension of the bending blade piece 3. FIG.

  Further, the same number of roll members 31a as the number of bent blade pieces 3 arranged on one side of the corrugated paper sheet P are brought into contact with each of the bent blade pieces 3 arranged on one side of the cardboard paper sheet P. It can also be placed on both sides. Furthermore, the roll member 31a is arranged on both sides of the transfer path 22 and is arranged in front of the roll member 31a by one roll member 31a or a plurality of roll members 31a arranged corresponding to the width dimension of one bent blade piece 3. It is also possible to constitute the bent blade pieces 3 that are intermittently bent in order.

  After each folding blade piece 3 of the corrugated paper sheet P is bent along the first fold line L1 of the corrugated paper sheet P in the first folding forming section 30-1, the corrugated paper sheet P becomes a second folding line L2. It is transferred to the second bend forming part 30-2 to be bent along. As shown in FIG. 3C, in the second bend forming unit 30-2, the transfer of the corrugated cardboard P transferred from the first bend forming unit 30-1 through the transfer path 22 is temporarily stopped. Then, the cardboard paper P is bent along the second folding line L2. At this time, the holding plate 33 is inserted from the horizontal direction into a portion corresponding to the bending position of each end unit substrate 2 on the upper surface of the cardboard paper P.

It can reciprocate alternately between the part 40 and the winding device 50 respectively installed in the right-and-left side part.

  In the frame mounting part 40, before the hollow rectangular body A of the winding frame 1 is sucked and held, the winding frame body transfer device 41 is in a posture capable of sucking and holding the winding frame 1 assembled by the square tube forming part 30-4. Is controlled in position and posture. Thereafter, the reel body transfer device 41 is lowered to a position for holding the hollow rectangular body portion A of the reel 1, sucking and holding the outer peripheral surface of the hollow rectangular body portion A, and sandwiching the side surface of the hollow rectangular body portion A and the like. To do. Next, the opening side of the hollow rectangular body A of the held reel 1 is moved toward the winding shaft portion of the winding device 50. Thereby, as shown in FIG.3 (f) and FIG.3 (g), the hollow square trunk | drum A of the winding frame 1 can be fitted on the winding shaft part of the winding device 50. FIG.

  In addition, although the structure provided with the attraction | suction member and the pinching member was demonstrated as the reel body transfer apparatus 41, as the reel body transfer apparatus 41, it is not limited to the same structure, The reel 1 is a cylinder. As long as it is a transfer device that can be transferred from the part forming unit 30-4 to the winding device 50, a transfer device of another configuration can be used as the reel body transfer device 41.

Next, the winding shaft portion of the winding device 50 will be described with reference to FIGS. 4 and 5. 4 and 5 show examples of the structure of the reel holding mechanism 51 of the typical winding device 50 of the present invention.
4 and 5, a winding device 50 includes a central shaft 52 that is driven and rotated by a rotation driving motor (not shown), and a reel holding mechanism that is slidably supported by the central shaft 52 and is rotatably supported. 51. The reel holding mechanism 51 supports the hollow rectangular body A of the reel 1 from the inner surface, and each of the folded blade pieces 3 previously folded in the first bent forming portion 30-1 is hollow. It is possible to maintain the bent posture of each bent blade piece 3 that is bent at a substantially right angle with respect to the rectangular body portion A and radially into a flange portion B, which is the flange portion B.

  As the winding frame holding mechanism 51, four frame members 53,..., 53 arranged around the axis of the central shaft 52 in the winding device 50 and the diameter of rotation toward the insertion side of each frame member 53 are reduced. A frame material holding part having a diameter changing means that can be enlarged can be provided. When the hollow rectangular body is formed in a polygonal shape, the number of frame members 53 corresponding to each end surface of the polygonal shape can be used.

  Link members 55 are rotatably supported on four projecting pieces 52a,..., 52a projecting radially, formed at the tip of the central shaft 52 of the winding device 50. Four spoke members 54a,..., 54a extending radially are integrally projected from a sliding cylinder 54 that is slidably inserted into the rear end portion of the central shaft 52. Each of the link member 55 and the spoke member 54 a has the same length, and is set to have the same height depending on the swinging posture of the link member 55.

  A longitudinally bent posture bent at a right angle toward the outside at both ends in the longitudinal direction of the frame member 53 rotatably supported by the distal end portion of the link member 55 and the distal end portion of the spoke member 54a. The holding pieces 53a and 53a are integrally formed. When the link member 55 rises, each frame member 53 can be configured to be parallel to the axis of the central shaft 52 at a predetermined interval.

  The link member 55 can be rotated by sliding the sliding cylinder 54 back and forth along the central axis 52 of the winding device 50 by a required stroke. As shown in FIG. 5, the frame member 55 can be inserted into and removed from the hollow rectangular body A of the winding frame 1 from the winding frame holding mechanism 51 of the winding device 50 in a state where the tip end portion is inclined forward and downward. it can.

  As shown in FIG. 5, each frame member 53 can be mounted so that the hollow rectangular body A of the winding frame 1 is fitted to the outer surface of each frame member 53 in the inclined state of the front lowering. At this time, the bent blade piece 3 on the front end side in the insertion direction of the winding frame 1 comes into contact with the inner side of the rear end side bent posture holding piece 53a of each frame member 53, and the first bent forming portion 30- 1 can be bent at a right angle outwardly along the first folding line L1. As a result, one of the flange portions B can be formed.

  From the state where the flange B on one side is formed, the engaging member 57 provided on the cylinder rod end 56 is engaged with the engaging member 57 and engaged with the annular flange 54b formed on the sliding cylinder 54. Thus, the frame member 53 can be made parallel to the central axis 52 by moving the cylinder rod end 56.

  At this time, the inner surface on the front end side of the bent blade piece 3 is in contact with the front end side bending posture holding piece 53a of the frame member 53, and the first bent forming portion 30-1 is bent in advance. The wing piece 3 is bent outward at a right angle along the first folding line L1. The flange portion B of the winding frame 1 at the time of winding the long material is formed by the respective bent blade pieces 3 bent at right angles from the opening at both ends of the hollow rectangular body A, and the formed flange portion B It is held by the bent posture holding pieces 53a on the side and rear end sides. By making the front end side of the frame member 53 have a small diameter, the reel 1 can be easily detached from the reel holding mechanism 51 of the winding device 50.

After the winding frame 1 is mounted on the winding device 50, the front end of the fastener chain F supplied from the long material supply unit 60 shown in FIG. The fastener chain F, which is a long material, can be wound around the peripheral surface of the hollow rectangular body A of the winding frame 1 by a predetermined amount. When the winding of the fastener chain F onto the winding frame 1 is completed, the winding end portion of the fastener chain F is cut at the long material supply unit 60, and the fastener chain F is attached to the next new winding frame 1. In order to supply, the cut | disconnected front-end | tip part is hold | maintained.
In this way, the winding operation of the fastener chain F can be saved and automated, and the packing operation of the fastener chain F can be performed very efficiently.

  In the automatic packing machine 10 of the present invention, as shown in FIGS. 1 and 2, the flange portion B is folded toward the winding peripheral surface of the fastener chain F wound around the winding frame 1 by the winding device 50 and folded. The bending / joining part 70 which is the characteristic part of this invention which connects the edge parts of the flange part B and packs the fastener chain F can be provided.

  The winding device 50 can index and position between the mounting position of the winding frame 1 by the frame body mounting portion 40 and the removal position of the winding frame 1 after the winding and winding of the fastener chain F are completed. In the folding / joining portion 70, the flange portion B of the winding frame 1 is folded toward the winding peripheral surface of the fastener chain F in the winding frame 1 around which the fastener chain F is wound, and the end portion of the folded flange portion B is folded. The operation of connecting and fixing each other can be automatically performed continuously.

  The folding operation of the flange portion B by the bending / joining portion 70 and the connecting and fixing operation of the end portions of the folded flange portion B can be performed while the winding frame 1 is mounted on the winding device 50. The completed reel 1 can be removed from the winding device 50, and the removed reel can be attached to a support device or the like that can be indexed and positioned. When the work by the folding / joining portion 70 is performed in a state where the winding frame 1 is mounted on the winding device 50, the winding shaft of the winding device 50 is intermittently positioned and rotated, and the pair of flange portions B to be folded are sequentially bent. It is desirable that the work position by the coupling unit 70 be indexed and controlled.

  The mechanism / structure of the bending / coupling portion 70 will be specifically described below with reference to FIGS. FIG. 6 schematically shows a main part of the folding / joining unit 70 in the automatic packing machine 10 of the present invention. In the same figure, the folding / joining part 70 has a folding mechanism 71 that folds a pair of flange parts B to be bent inwardly, and the folded ends of the flange parts B to each other. And a coupling mechanism 72 that is bonded and bonded. The bending mechanism 71 includes a rotary bending means 73 that folds the opposing flange portions B inwardly, and a bending plate 74 that assists the folding of the flange portions B.

  The bending mechanism 71 is incorporated in a support frame 75 having a substantially U-shaped cross section. The support frame 75 is fixedly supported on the rod end of the first elevating cylinder 75a which is the first elevating means, and the lower ends of a pair of guide rods 75b and 75b arranged on both sides of the rod are fixed. Yes. Each guide rod 75b is inserted into a cylindrical guide member 75c disposed in parallel with the first elevating cylinder 75a, and the support frame 75 is guided and extended by the expansion and contraction of the first elevating cylinder 75a. Can be slid along. Thereby, the said support frame body 75 can be raised / lowered between the standby position above the winding frame 1 which wound up the fastener chain F, and the folding position which folds the flange part B. FIG.

  Each turning bending means 73 of the bending mechanism 71 includes a turning member 73a that is rotated by a rotation driving motor (not shown), and a fork-like member that is a bending member provided on the outer peripheral surface of the turning member 73a. 73b. The rotation bending means 73 is rotatably supported in the vicinity of both left and right side portions of the support frame 75 with a predetermined interval. As shown in FIGS. 7 (b) and 7 (c), they can be sequentially rotated in a direction of bowing with a predetermined time difference, and the state can be maintained after the rotation.

  As shown in FIGS. 7 and 8, the bending plate 74 of the bending mechanism 71 has a width dimension that is substantially the same as the distance between the pair of flange portions B facing each other. The bending plate 74 is supported so as to be in a horizontal state at the rod end of the operating cylinder 74a connected and fixed to the support frame 75. The operating cylinder 74a can operate in a direction perpendicular to the sliding direction of the first elevating cylinder 75a.

  The operating cylinder 74a can be operated independently of the first elevating cylinder 75a. By actuating the operation cylinder 74a, the back surface of the bending plate 74 is positioned on the winding peripheral surface of the fastener chain F (see FIGS. 7B and 7C) and a standby position separated from the same position ( 7 (a) and 7 (d)).

  Further, by the operation of the first elevating cylinder 75a, the back surface of the bending plate 74 can be brought into contact with the winding peripheral surface of the fastener chain F as shown in FIGS. That is, as shown in FIG. 7 (d), each flange portion folded on the upper surface of the bending plate 74 by operating the operating cylinder 74a in a direction opposite to the operating direction from the state of FIG. 7 (a). Pull out to a standby position separated from B.

  FIG. 7 schematically shows an operation example of the bending mechanism 71 in the bending / coupling unit 70 step by step. As shown in FIG. 7 (a), the winding mechanism 71 of the bending / joining unit 70 waiting in the upper standby position is extended by extending the rod of the first elevating cylinder 75a shown in FIG. 50 is lowered toward the bent position of each flange portion B in the reel 1 in a state of being attached to 50. When the fork-like member 73b is positioned at a position that matches the folding height position of the flange portion B, the rod of the operating cylinder 74a is extended to move the bending plate 74 to a position facing the winding peripheral surface of the fastener chain F. .

  At this time, the bending plate 74 is inserted between the pair of flange portions B, and can be brought into contact with the winding peripheral surface of the fastener chain F. The bending mechanism 71 and the bending plate 74 may be lowered integrally by operating the first elevating cylinder 75a after the bending plate 74 is moved to a position facing the winding peripheral surface of the fastener chain F. it can.

  At this time, since the side edge of the bending plate 74 can be arranged along the bent ridge line portion of each flange portion B, the bent ridge line portion of each flange portion B is deformed into an irregular shape and folded. Or it can prevent that the folding position of the flange part B which opposes differs. For this reason, it can be folded accurately along the side edge of the bending plate 74 in a straight state substantially perpendicular to the central axis of the winding frame 1.

  As shown in FIG. 7B, by rotating one rotating member 73a, the fork-like member 73b of the rotating member 73a presses the side surface of the one flange portion B while facing the bending plate 74 side. Can be folded inward along the edge. The fork-like member 73b in which the flange portion B is folded can stop its rotation and maintain its folded posture.

  As shown in FIG. 7C, by rotating the other rotating member 73a with a predetermined time difference, the fork-like member 73b of the rotating member 73a presses the side surface of the other flange portion B. However, it is possible to fold the flanged portion B folded inward along the side edge of the bending plate 74 and overlap the end portion of the flange portion B folded later on the end portion of the lunge portion 3 folded earlier.

  As shown in FIG. 7C, after the flange portions B are folded inward so as to bow, the rotation of the fork-like member 73b is stopped and the folded posture of the flange portion B can be maintained. . Thereby, it becomes possible to continuously and efficiently perform the folding operation of each flange portion B and the maintenance operation of the folded form, and quickly and smoothly between the end portions of the next flange portion B. It is possible to move on to the combined work.

  As shown in FIG. 7D, in a state where the folded form of each flange portion B is maintained by a pair of fork-like members 73b, the bending plate 74 is made to contract by contracting the rod of the operating cylinder 74a. It can be moved horizontally to the retracted position alone.

  In this way, the bending plate 74 can be moved up and down in cooperation with the turning and bending means 73, and the lower surface position and the lower surface position of the flange portion B folded independently by the operation of the operation cylinder 74a. It is possible to reciprocate in the horizontal direction between the standby positions separated from the center. By providing the bending plate 74, as shown in FIG. 8, the bent ridge line part of each flange part B can be formed into a shape substantially orthogonal to the central axis of the winding frame 1, and the flange part is clean and accurate. B can be folded.

  Moreover, since the folding form of each flange part B can always be ensured in a fixed shape, the end parts of each flange part B can be reliably stuck with the whole sticking surface of a sticking tape. Become. Thereby, the sticking retention strength of the sticking tape can be increased. Furthermore, it becomes possible to stick the sticking position and sticking form of the sticking tape to the reel in a position and form that does not impair the appearance of the package by the sticking tape, and has a stable form. A high-quality finished product can be obtained. In addition, it is possible to reliably prevent the collapse of the package and the damage of the corrugated cardboard during the storage and transportation of the finished packaged product.

  As the bending mechanism 71, the fork-like member 73b which is the bending member can also be used as a bending maintaining means. Further, the rotating member 73a, the fork-like member 73b, the first elevating cylinder 75a, the bending plate 74, the working cylinder 74a for the bending plate 74, and the like constituting the bending mechanism 71 are integrated and integrated. can do. Thereby, size reduction and unitization of the bending mechanism 71 can be achieved, and the installation space of the entire apparatus can be reduced.

  As the coupling mechanism 72 for coupling the ends of the folded flange portions B to each other, a configuration using a tape adhering means 76 as shown in FIG. 6 can be used. As the coupling mechanism 72, a second elevating cylinder 72a as a second elevating means provided in parallel with the first elevating cylinder 75a, and at least one end surface and the other flange of each of the flange portions B to be folded are used. A tape adhering means 76 for adhering the adhering tape T in a substantially L-shape is provided over the two sides of the part B beyond the bent ridge line part.

  The tape adhering means 76 presses the end of each flange portion B to press the adhering tape T and adhering the side surface including the bent ridge line portion in one flange portion B inward. And it has the vertically long side sticking plate 78 which sticks the sticking tape T on the side of the flange part B. The tape sticking means 76 is moved up and down by the second lift cylinder 72a, and the second lift cylinder 72a is configured to extend and contract independently in the vertical direction independently of the first lift cylinder 75a. it can.

  One end of the sticking pusher 77 is fixed to the rod ends of a pair of guide rods 77a that are slidably supported by the side face sticking support plate 78a. A compression spring 77b is interposed in the guide rod 77a between the sticking pusher 77 and the side sticking support plate 78a. By the compression spring 77b, the adhesive tape T held by the adhesive pusher 77 can be elastically pressed and adhered to the surface of each flange portion B folded by the adhesive pusher 77. Further, the compression spring 77b can be made to function as a damper means that maintains the pressed state and allows the side surface attaching plate 78 to move further downward along the side surface of the reel 1.

  The side sticking plate 78 can be moved up and down together with the sticking pusher 77 between a standby position immediately above the reel 1 around which the fastener chain F is wound and a folded surface position of each flange portion B. The side sticking plate 78 is extended and fixed downward from one side of the side sticking support plate 78a connected and fixed orthogonally to the rod end of the second elevating cylinder 72a.

  The adhering pusher 77 and the side adhering plate 78 have a dimensional shape capable of passing the interval between the forks in the fork-like member 73b. Further, the side sticking plate 78 further has a dimensional form capable of passing through a gap formed between the inner surface of the fork base in the fork-like member 73b and the side face of the winding frame 1.

  In addition, the fork-like member 73b positioned at least on the side surface adhering plate 78 side is rotated in a state where the end portions of the flange portion folded by the adhering pusher 77 are adhered and pressed by the adhering tape. Thus, it can be separated from the folded flange portion B. In this case, the dimension of the side sticking plate 78 is such that it can pass between the rotating bending means 73 and the side surface of the reel 1 on the side of the fork-like member 73b that is rotated and separated. It can be.

  The tip of the side sticking plate 78 is formed to be smoothly curved so as to protrude outward. By the operation of the second elevating cylinder 72a, the side sticking plate 78 is moved downward along the side face of the reel 1 while compressing the compression spring 77b, whereby the sticking tape held by the sticking pusher 77. The extended sticking tape T can be stuck to the side face side of the flange portion B while supporting the extending piece of T toward the side sticking plate 78 side.

  As shown in FIG. 10, by the tape adhering means 76, it is applied from the surface of at least one end of the flange portion B to the side surface beyond the bent ridge line portion of the other flange portion B folded oppositely. The adhesive tape T can be attached in a substantially L shape. After folding both flange parts B so that the end part surface of one flange part B overlaps the end part surface of the other flange part B, the end of the other flange part B from the end part surface of one flange part B By sticking the adhesive tape T on the side surface beyond the bent ridge line part of the other flange part B through the part surface, the adhesive strength by the adhesive tape T can be increased.

  That is, by sticking the sticking tape in a substantially L shape, for example, due to the restoring force of the flange part B, the end of each flange part B is lifted, and the gap between the flange parts B is expanded outward in a double-spread state. The force to rise up acts and tries to peel off the adhesive tape. However, since the adhesive tape is attached in a substantially L shape from the surface of at least one end of the flange portion B to the side surface beyond the bent ridge line portion of the other flange portion B, the adhesive tape Adhesion retention strength can be greatly increased. Thereby, it can prevent that a sticking tape peels.

  When folding of the pair of flange parts B by the bending / joining part 70 and the sticking with the sticking tape T between the folded flange parts B are finished, the reel 1 is indexed by 90 degrees, and the next pair of flange parts B is indexed. It folds with respect to the flange part B, and the sticking by the sticking tape T between the folded flange parts B is performed. This is sequentially repeated, and the packing operation of the fastener chain F by the reel 1 is completed.

  As shown in FIG. 10, the finished product of the fastener chain F packed in the reel 1 can be taken out from the take-up device 50 via the reel discharge device 82 shown in FIG. 2. The taken out package is discharged to the finished product stocker 81 and stored. In addition, a package is formed along a pair of 2nd crease line L2 which defines the intermediate unit board | substrate 2a of the winding frame 1, and each 2nd crease line L2 which defines each edge part connection piece 2b of the winding frame 1. By flattening, that is, by crushing the packing body in the direction of the arrow in FIG. 10, a substantially rectangular parallelepiped packing body can be formed into a flat packing body.

  The index angle of the reel 1 is set according to the number of the left and right pair of flange portions B formed. For example, even in the case of the above-described embodiment, one hollow square body portion A is placed. In the case where a pair of flange portions B are formed, that is, when two sets of flange portions B are formed on the winding frame 1, the indexing angle is 180 degrees. The indexing of the reel 1 can be performed with the reel 1 mounted on the winding device 50, or can be performed by separately mounting a reel that has been wound on the indexing device.

  FIG. 9 shows a second embodiment related to the coupling mechanism 72 that couples the end portions of the flange portions B to each other, and schematically shows an operation example of the coupling mechanism 72. In Example 2, the point which comprised the adhesion pusher 87 by the hollow block body, and the structure accompanying having made it the hollow block body differ from the structure of the adhesion pusher 77 in Example 1. FIG. However, other configurations have the same configuration as the configuration in the first embodiment, and the description of the components is omitted by using the same component codes as those used in the first embodiment.

  In Example 2, the sticking pusher 87 is formed of a hollow block body. The hollow block body has a dimension that allows passage between the forks of the fork-like member 73b. As shown in FIG. 9, the internal structure of the hollow block body includes a suction chamber 87c communicating with a vacuum suction source (not shown). An open / close valve or the like (not shown) is disposed in a circuit that communicates the suction chamber 87c with a vacuum suction source. On the pressing surface of the sticking pusher 87, an elastic body 87e such as a rubber material or sponge having a plurality of vent holes 87d,..., 87d communicating with the suction chamber 87c is disposed.

  The sticking tape T supplied from the sticking tape supply means (not shown) is sucked and held by the pressing surface of the sticking pusher 87 in the form of a tape piece, and a part of the sticking tape T sucked and held is a side surface. It is in the state extended to the sticking plate 78 side. From this state, as shown in FIG. 9A, the second elevating cylinder 72 a is operated to lower the coupling device 72 toward the end of each flange portion B of the reel 1. The sticking tape T sucked to the pressing surface of the sticking pusher 87 that has passed between the forks of the fork-like member 73b is stuck between the folded end portions of the folded flange portion B. Further, the surface of the flange portion B can be elastically pressed and supported by the pressing surface of the sticking pusher 87.

  When the rod of the second elevating cylinder 72a is further extended as shown in FIG. 9 (b), the sticking pusher 87 elastically presses the surface of the folded end of each flange B, while the side sticking. The landing plate 78 can be moved downward along the side surface of the reel 1 against the elasticity of the compression spring 87b. Thereby, in the state which maintained the folding form of each flange part B, the sticking tape T extended to the side sticking plate 78 side is stuck in order toward the side surface including the bending ridgeline part of the flange part B. I can go. When the side sticking plate 78 moves downward, the side sticking plate 78 can pass through the gap formed between the inner surface of the base of the fork-like member 73b and the side face of the reel 1.

  Subsequently, as shown in FIG. 9C, when the rod of the second elevating cylinder 72a is further extended, the side surface adhering plate 78 presses the side surface including the bent ridge line portion of the flange portion B inward. The adhesive tape T can be sequentially attached downward along the side surface of the reel 1 while sliding. Thus, after adhering the adhesive tape T while pressing the end surface of the flange portion B, the side including the bent ridge line portion of one flange portion B is pressed inward with a time difference. The sticking tape T can be stuck in a substantially L shape without unevenness. In addition, while adjusting the form of the packaging body of the reel 1 and the flange portion B, it is adhered over two surfaces from between the end portions of the overlapping flange portions B to one side surface beyond the bent ridge line portion of the flange portion B. The tape T can be stuck in a substantially L shape.

  Thus, when the folding operation of the flange portion B on one surface of the four surfaces of the winding frame 1 and the joining operation of the end portions of the flange portion B are completed, the winding device 50 is indexed by 90 °. The adjacent unworked flange portion B can be set upward. Thereafter, the same operation as the above operation is sequentially repeated to perform the folding operation of each flange portion B and the joining operation of the end portions of each flange portion B on the remaining three surfaces of the reel 1. All the folding and joining operations of B can be completed.

  By connecting the suction chamber 87c to the vacuum suction source, the non-stick surface of the sticking tape T can be held on the pressing surface of the sticking pusher 87 by the vacuum suction source so as to be sucked and released. The end portions of the opposing flange portions B can be coupled to each other. By providing the adhesive pusher 87, the adhesive tape T can be securely held with a simple structure, and the flange tape B can be folded while the adhesive tape T is adapted to the folded surface of each flange B. It is possible to ensure close contact along the shape of the surface.

  By this invention, the folding operation | work of each flange part B and the joining operation | work of the edge parts of each flange part B can be performed smoothly and continuously. In particular, the adhesive tape T is adhered to the side surface of each flange portion B beyond the bent ridge line portion by adhering between the surface portion and the side surface of each flange portion B of the reel 1 in a substantially L shape. The adhesive strength of the adhesive tape T can be increased by the adhesive strength of the applied tape portion, and the adhesive tape T can be easily prevented from peeling off. For this reason, it is possible to prevent the collapse of the load at the time of storing or transporting the reel 1 and the damage of the corrugated cardboard as the packaging material.

  After all the bending work and the joining work of the flange portion B of the reel 1 are completed, the reel holding mechanism 51 of the winding device 50 and the reel 1 attached to the reel holding mechanism 51 are fitted. By releasing the state, the reel 1 can be maintained in a state where it can be taken out, and the reel discharge device 82 shown in FIG. 2 is moved to the lower surface of the reel 1, so that the reel 1 is removed. After being held at 82, the hollow rectangular body A of the reel 1 can be taken out of the reel holding mechanism 51 and moved to the finished product stocker 81 to be discharged.

  The coupling mechanism 72 can be installed in parallel with the folding mechanism 71 at a standby position immediately above the reel 1. In addition, the folding mechanism 71 and the coupling mechanism 72 can be operated sequentially and continuously in a state in which the reel 1 is always kept at a certain carry-in position, thereby speeding up the work. This can be achieved and the working efficiency can be greatly improved.

  The coupling mechanism 72 that couples the folded end portions of the flange portions B to each other can be installed in parallel with the folding mechanism 71 of the flange portion B at a standby position immediately above the winding frame 1. Can be performed sequentially and continuously in a state where the machine is always in a standby state at a certain carry-in position, and the operation of the coupling mechanism 72 can be performed sequentially and continuously. Efficiency can be greatly improved.

  As is clear from the above description, in the folding / joining portion 70, when the fastener chain F wound up using the winding frame 1 wound up with the fastener chain F is packed, the folding / joining portion 70 is substantially aligned with the central axis of the winding frame 1. The operation of folding the flange portions B extending orthogonally toward the winding peripheral surface of the fastener chain F and the operation of joining the end portions of the folded flange portions B to each other are continuously performed without human intervention. It can be done automatically.

  The labor saving of the packing operation makes it possible to smoothly and continuously perform various operations from the corrugated cardboard to the winding frame body assembling and the winding of the fastener chain F to the packing. It is possible to achieve rationalization and automation of the packing work.

  In particular, the folding mechanism 71 can stabilize the folding form of each flange B, and the coupling mechanism 72 can improve the connection strength between the ends of each flange B. . Moreover, the connection strength of the edge parts of each flange part B can be increased by stabilizing the folding form of each flange part B. For this reason, it is possible to prevent the collapse of the load at the time of storage and transportation of the fastener chain F, the damage of the corrugated cardboard, and the like.
