Description

  The present invention relates to a method for manufacturing a reinforcing bar network and an apparatus therefor, which are useful for manufacturing a flat reinforcing bar network formed by binding each intersection of a plurality of vertical bars and a plurality of horizontal bars crossing the vertical bars.

  A reinforced concrete slab as a building material is manufactured by embedding a reinforcing reinforcing bar net in concrete, and a manufacturing apparatus for efficiently manufacturing the reinforcing bar net in this case has been proposed (Patent Document 1).

  A conventional rebar net manufacturing apparatus includes, for example, a frame-shaped positioning jig that holds a plurality of vertical bars and horizontal bars intersecting in a plane, a girder that moves above the positioning jig in parallel with the vertical bars, It includes a saddle that moves on the girder in parallel with the lateral stripes, and a binding machine that is mounted on the saddle so as to be able to move up and down. That is, the binding machine can be moved arbitrarily in the vertical and horizontal directions via the girder and saddle, and the crossing portions of the vertical and horizontal bars on the positioning jig can be bound to form a reinforcing bar network. Note that the binding machine uses a set of two units whose binding directions are different by 90 ° from each other, for example, by reversing the binding direction of the adjacent intersections on each horizontal bar to improve the stability of the reinforcing bar network. And In addition, instead of a frame-shaped positioning jig, a similar system that places the vertical and horizontal bars automatically on a large reinforcing steel frame via a dedicated vertical and horizontal bar arrangement device. Is also known (Patent Document 2).

  When using such a conventional technique, the longitudinal bars and the horizontal bars before binding that form the reinforcing bar network are arranged in advance by crossing each other, and the crossing portions are sequentially moved while moving the binding machine vertically and horizontally above them. Since they are tied together, it is complicated to carry in the vertical and horizontal bars before binding and to carry out the reinforcing bar network after binding, and the binding efficiency is poor and it is not easy to improve the binding efficiency. It was.

  Therefore, in view of the problems of the prior art, an object of the present invention is to arrange the longitudinal and transverse muscles by arranging two rows of front and rear binding devices so as to cross the traveling direction of a plurality of longitudinal muscles. It is an object of the present invention to provide a method for manufacturing a reinforcing bar net and an apparatus for the same that can easily carry out the net and maximize the binding efficiency.

  In order to achieve this object, the structure of the first invention according to this application (referred to as the invention according to claim 1, the same shall apply hereinafter) includes a plurality of vertical arrangements arranged in parallel in one plane and advanced in the length direction. The front and rear two rows of binding machines are arranged so as to cross the direction of travel of the muscles, and the binding machines in each row correspond to the odd and even numbers of the vertical bars, respectively, and the binding direction with respect to the vertical direction of the vertical bars When the horizontal muscle attachment position reaches the binding position of the rear row binding machine, the horizontal muscle is supplied onto the vertical muscle corresponding to the binding position of the rear row binding machine. The back row binding machine is operated all at once to bind the intersection of the vertical and horizontal bars, and when the horizontal line on the vertical line reaches the binding position of the front row binding machine, the front row binding machine is operated all at once. The gist is to bind the crossing of the horizontal bars and repeat the same operation below. That.

  When the horizontal bar on the vertical line reaches the binding position of the binding machine in the front row and at the same time the mounting position of the horizontal bar reaches the binding position of the binding machine on the rear row, the horizontal bar on the vertical line corresponding to the binding position of the binding machine in the rear row The front row and back row binding machines can be operated at the same time, and the horizontal muscle on the vertical line reaches the binding position of the front row binding machine before the horizontal line is attached to the binding position of the rear row binding machine. , The horizontal streaks can be supplied onto the vertical streaks corresponding to the binding positions of the back row binding machines and the back row binding machines can be operated simultaneously.

  The configuration of the second invention (referring to the invention according to claim 4, the same shall apply hereinafter) includes a plurality of guides that individually guide the longitudinal stripes and advance in parallel in one plane, and cross the front of the guides. It comprises a bundling machine arranged in two front and rear rows, and a conveying device that feeds horizontal stripes to the bundling position of the rear row bundling machine. The bundling machine in each row corresponds to the odd-numbered and even-numbered guides, respectively. The gist is to incline the binding direction in the opposite direction with respect to the extending direction.

  Each guide can be set to move left and right, each binding machine can be set to move left and right, and the front row binding machine can be set to move back and forth in a lump. It can be mounted on a slide base that can be set to move left and right together with a reel stand that detachably holds a reel of wire for bundling. Between each reel and each bundling machine, a common wire drawer The roller can be translated up and down.

  Further, the horizontal stripe from the conveying device may be positioned in the front-rear direction via the receiving member, centered via the left and right pushers, and constrained on the vertical stripe via the clamper.

  According to the configuration of the first aspect of the invention, the front and rear two rows of binding machines arranged so as to cross the direction of travel of the vertical bars correspond to the odd and even numbers of the vertical bars, respectively. The binding direction is inclined in the opposite direction. Therefore, by moving the longitudinal muscles all at once, supplying the transverse muscles on the longitudinal muscles and operating the binding device in the back row at the same time, out of the intersections of the transverse and longitudinal muscles on the longitudinal muscles, The other half is tied together, and then the back row bundling machine is moved forward to the bundling position of the front row bundling machine, and the front row bundling machine is operated all at once. When the remaining half of the crossing portions of the horizontal and vertical muscles are bound at once, all of the crossing portions of the horizontal and vertical muscles on the vertical muscles can be bound. At this time, the crossing portions on the horizontal bars are alternately opposite in the binding direction, and the rebar net can be completed by repeating the same operation thereafter.

  That is, according to the first aspect of the present invention, by repeating the supply operation of the horizontal muscles and the binding operation by the binding machine in each row while advancing all the vertical muscles all at once, It is possible to smoothly carry out the subsequent rebar net unloading at the same time. In addition, the front and rear two-row binding machines can be operated simultaneously for each row to complete all the binding at the intersection of each horizontal and vertical bars, maximizing the binding efficiency when manufacturing the reinforcing bar network Can be improved. Note that the number of bundling machines in each row is equivalent to half the number of vertical bars.

  When the front row and rear row binding machines are operated at the same time, the cycle time can be further shortened as compared with the case where each row binding machine is operated separately. However, at this time, the binding machine in each row sets the interval in the front-rear direction so as to match the pitch of the horizontal bars on the reinforcing bar network, so that the horizontal bars on the vertical bars reach the binding position of the binding machine in the front row. It is assumed that the timing coincides with the timing at which the horizontal stripe mounting position reaches the binding position of the back row binding machine.

  Before the horizontal bar on the vertical line reaches the binding position of the binding machine in the front row, the horizontal line is supplied to the mounting position of the horizontal line that reaches the binding position of the back row binding machine, and the back row binding machine is operated to perform binding. For example, the horizontal bars can be bundled on the vertical bars at a pitch smaller than the distance in the front-rear direction of the binding machines in each row, and the width of the horizontal bars smaller than the minimum dimension that can be mechanically realized as the spacing between the binding machines in each row The pitch can be realized on a reinforcing bar net.

  According to the configuration of the second invention, since the plurality of guides individually guide the vertical bars, for example, by pressing the rear end of the vertical bars in each guide all at once, It can be advanced in the length direction. Therefore, by combining the front and rear two-row binding machines in front of the guide and the transport device that supplies the horizontal streak to the binding position of the rear-row binding machine, the first invention can be implemented smoothly and the effects of the first invention can be realized. can do. The binding machine in each row corresponds to the odd-numbered and even-numbered guides and tilts the binding direction in the opposite direction with respect to the extending direction of the guide. This is because half of the bars corresponding to every other line are bound in the opposite direction, and the same operation is repeated to complete the reinforcing bar network.

  By making each guide and each binding machine move to the left and right, the pitch of the vertical stripes can be set arbitrarily. Each guide may be manually settable or automatically settable. The same applies to each binding machine. Each guide and each binding machine may be set to move independently of each other, or may be set to move in conjunction with each other so that the latter corresponds to the former odd number and even number. On the other hand, the binding device in the front row can be set to move back and forth in a lump, so that the distance from the binding device in the back row can be set arbitrarily, and the pitch of the horizontal stripes can be set arbitrarily.

  When each bundling machine is mounted on a slide base together with a reel stand for reels of bundling wires, the relative positional relationship with the reels does not change even when set to move left and right, and the wires are always drawn smoothly from the reels. be able to.

  The wire drawing-out common roller is lowered between each reel and each bundling machine, so that a bundling wire having a predetermined length can be drawn at once from a plurality of reels on a plurality of slide bases. However, the wire drawing roller is a horizontal roller, and a guide wheel with a clamp function having a one-way clutch, for example, is provided on each slide base in order to prevent the wire from returning from the binding machine when the roller is lowered. The wire is guided to the binding machine through the guide wheel.

  When supplying the horizontal streak from the transport device to the mounting position of the horizontal streak on the vertical streak, it is positioned via the receiving member, centered via the pusher, and restrained via the clamper, so that Position and bind to create a highly accurate rebar net

However, FIGS. 5A and 5B are a top view and a side view of the main part including the slide base 14, respectively.

  The binding machine 12 uses, for example, a reinforcing bar binding machine RB-399 manufactured by Max Co., Ltd., and is driven by an external power source based on an electrical signal from the outside. The binding machine 12 can insert a reinforcing bar between the upward hook 12a and the curl guide 12b and bind them through a binding wire W from the reel W1 on the reel stand 13. Therefore, in FIGS. 5A and 5B, the symbol N indicates the binding position of the binding machine 12. The binding machine 12 is mounted on a pedestal 14a on the slide base 14 together with a swing cylinder 12d and a wire guide 12e for the wire W via a lifting cylinder 12c.

  The reel stand 13 can rotatably hold the reel W1 of the wire W. The reel W1 is sandwiched between auxiliary flanges 13a and 13a with bosses, and the reel stand 13 supports the bosses of the auxiliary flanges 13a and 13a via a bearing (not shown) so as to be rotatable and detachable. The reel stand 13 is provided with a manual brake 13b for braking the auxiliary flange 13a, a wire guide 13c for passing the wire W from the reel W1, and the slide base 14 is provided with a lock handle 14b.

The binding machine 12 moves left and right through the slide base 14 together with the reel W1 on the reel stand 13. Movement setting is possible.

  On the base 14a for the binding machine 12, a guide wheel 15 with a flange for the wire W is installed via a support column 15a (FIGS. 5 and 6). 6A is an enlarged view of the main part of FIG. 5A, and FIGS. 6B to 6C are a right side view, a left side view, and a top view of FIG. 6A, respectively. It is.

  A one-way clutch 15b is attached to the guide wheel 15, and the guide wheel 15 can rotate only in the direction in which the wire W from the reel W1 is sent out toward the binding machine 12 (FIGS. 6A and 6D). ) Each arrow direction). The guide wheel 15 is combined with a clamping cylinder 15c for clamping the wire W, and the wire W passing through the guide wheel 15 can be clamped by extending the cylinder 15c. However, the cylinder 15c is not shown in FIGS. 5 (A) and 6 (D). Wire guides 15d and 15e for the wire W are provided on the reel stand 13 side and the binding machine 12 side of the guide wheel 15, respectively. The wire guide 15d on the reel stand 13 side has a slit 15d1 that is long in the vertical direction. Is formed.

  The front row binding machine 12, the reel stand 13, and the slide base 14 are formed substantially symmetrically with respect to FIGS. 5 and 6 (FIG. 1). A guide plate 15f of almost the same level as the guides 11, 11... Is attached to the support columns 15a for the respective guide wheels 15 corresponding to the front row binding machines 12, 12,. ).

  In the rear fixed frame 31 and the front moving frame 33, a drawing roller 34 for the wires W, W... And a guide roller 35 for the wires W, W. The roller 35 is rotatably supported so as to horizontally traverse the vicinity of the reels W1, W1 on the reel stands 13, 13... Via bearings 35a, 35a at both ends fixed to the fixed frame 31 or the moving frame 33. (FIGS. 1 and 2). On the other hand, the roller 34 is provided via left and right cylinders 34a, 34a installed downward in the fixed frame 31 or the moving frame 33, and bearings 34c, 34c on slide members 34b, 34b connected to the tips of the cylinders 34a, 34a. The roller 35 and the guide wheels 15, 15..., That is, the reels W1, W1... And the binding machines 12, 12. A) each solid line, two-dot chain line). The slide members 34b and 34b move up and down along slide rails (not shown) when the cylinders 34a and 34a are expanded and contracted.

  On each slide base 14, the binding wire W from the reel W1 is supplied to the binding machine 12 through the wire guide 13c, the roller 35, the guide wheel 15, and the wire guide 12e. However, on both sides of the guide wheel 15, wire guides 15d and 15e on the reel W1 side and the binding machine 12 side are provided.

  The pulling roller 34 is lowered from the upper retracted position (solid line in FIG. 5A) to the lower retracted position (two-dot chain line in FIG. 5), and immediately returned to the upper retracted position, so that the corresponding rear row Alternatively, the predetermined lengths of the wires W, W... Can be drawn out from the front reels W 1, W 1. However, when the roller 34 is lowered, the clamping cylinder 15c on each guide wheel 15 is temporarily extended to restrain the wire W, thereby preventing the wire W from being pulled back from the binding machine 12 side. Further, the lowering stroke of the roller 34 is set so that the extension strokes of the cylinders 34a and 34a can be stored so that the wire W corresponding to one bundling operation by each bundling machine 12 can be stored.

  Therefore, each binding machine 12 can smoothly perform the binding operation by using the wire W stored under the roller 34. When each binding machine 12 is activated and one wire W is consumed, the amount of storage under the roller 34 is reduced (the chain line in FIG. 5A), so the roller 34 is immediately lowered. The wires W, W... Corresponding to the next one time are raised from the reels W1, W1... To prepare for the next bundling operation.

  The left and right conveying devices 20 and 20 for supplying the transverse stripe Ry are arranged in the vertical direction between the front and rear fixed frames 32 and 31 (FIGS. 1 and 2). Each transport device 20 includes an endless chain 23 wound around the upper and lower sprockets 22 and 22 of a bracket plate 21 that is long in the vertical direction, and the chains 23 and 23 are driven by a common drive motor 24. The chain 23 is provided with hooks 23a, 23a,... That are transported downward with the horizontal stripes Ry. The chain 23 is attached to the bracket plate 21 along a chain guide (not shown) supported via spacers 23b, 23b,. Circulate up and down parallel to The upper sprockets 22, 22 are fixed to a common drive shaft 22a, and the drive shaft 22a is connected to the output shaft of the drive motor 24 via a drive chain 24a. 1 and 2, the conveying devices 20 and 20 and the common drive motor 24 are mounted on the front fixed frame 32, but these members may be mounted on the rear fixed frame 31. Good.

  The conveying devices 20 and 20 synchronously drive the chains 23 and 23 in the direction in which the respective upward hooks 23a, 23a... Descend downward (in the direction of arrow K1 in FIG. 1). Therefore, when each hook 23a rotates around the upper sprocket 22, a horizontal stripe Ry of a predetermined length is supplied one by one from a supply device (not shown) (in the direction of arrow K2 in the figure), and the transfer devices 20, 20 When it is passed over the hooks 23a, 23a at the same level, the transverse stripe Ry can be transferred by being translated downward via the transfer devices 20, 20.

  At the lower ends of the bracket plates 21 and 21 of the transfer devices 20 and 20, an attachment 21a is mounted to remove the horizontal stripe Ry on the hook 23a and transfer it to the receiving members 26 and 26 on the lower rear side (FIGS. 2 and 2). 7). A rearward claw 21a1 at the lower end of each attachment 21a is engaged from the lower side with respect to the transverse stripe Ry conveyed downward via the hooks 23a, 23a, and as each hook 23a rotates around the lower sprocket 22, (In the direction of the arrow in FIG. 7), the transverse muscle Ry can be reliably escaped from the hook 23a.

  The receiving members 26, 26 are mounted on a horizontal support member 36 in the rear fixed frame 31, along with the left and right pushers 27, 27 and clampers 28, 28, slightly below the rear side of the conveying devices 20, 20. FIG. 2, FIG. 7). The receiving members 26 and 26 and the clampers 28 and 28 are disposed inside the conveying devices 20 and 20, and the pushers 27 and 27 are disposed on both outer sides of the conveying devices 20 and 20.

  The claw member 26b can swing up and down around the pin 26c, and is biased to a fixed position obliquely upward via a coil spring 26d (solid lines in FIGS. 7 and 8A). A magnet 26e is attached to one surface of the main body bracket 26a via a mounting material 26f. A mounting bracket 26g with a mounting screw 26h is attached to the upper end of the main body bracket 26a. The claw member 26b at the fixed position is relatively directed to the lower end on the rear side of the transport device 20, and therefore, the horizontal streak Ry detached from the hooks 23a, 23a of the transport devices 20, 20 , 26 can be positioned in the front-rear direction along the front edge of the main body brackets 26a, 26a via the claw members 26b, 26b and the magnets 26e, 26e. When a downward or forward force is applied to the transverse muscle Ry on the claw member 26b, the claw member 26b swings downward against the coil spring 26d and takes a substantially horizontal position (see FIG. 8A). (Dotted line), the horizontal stripe Ry can be slightly lowered, or the horizontal stripe Ry can be moved forward relative to the arrow (in the direction of the arrow in the figure).

  The transverse stripes Ry are individually conveyed one by one by the conveying devices 20 and 20 and are positioned by the receiving members 26 and 26. The position of the transverse stripes Ry on the receiving members 26 and 26 is determined by the binding machine 12 in the rear row. It is assumed that 12 corresponds to the common binding position N (FIGS. 1 and 3). That is, the conveying devices 20 and 20 can supply the transverse stripe Ry to the binding position N of the back row binding machines 12, 12... Via the receiving members 26 and 26.

  Each pusher 27 has a push member 27a attached to the tip of a sideways cylinder 27b (FIG. 9). 9A and 9B are a right side view and a front view of the pusher 27, respectively.

  The cylinder 27b is fixed to the base bracket 27c, and a mounting bracket 27d with a mounting screw 27e is fixed to the base bracket 27c. The cylinder 27b is provided with a speed regulator 27f. The left and right pushers 27, 27 are opposed to each other with the transverse stripe Ry on the receiving members 26, 26 interposed therebetween via a support member 36 (FIG. 2). Therefore, the pushers 27 and 27 can center the transverse stripe Ry via the push members 27a and 27a by temporarily extending the cylinders 27b and 27b at the same time. However, the left and right pushers 27 and 27 are configured to be different from each other, and FIG. 9 illustrates the left pusher 27.

  Each clamper 28 has a pressing member 28a attached to the tip of a downward cylinder 28b (FIG. 10). 10A and 10B are a right side view and a front view of the clamper 28, respectively. The cylinder 28b is fixed to the base bracket 28c, and a mounting bracket 28d with a mounting screw 28e is fixed to the base bracket 28c. The left and right clampers 28 and 28 can press the transverse stripe Ry on the receiving members 26 and 26 downward by extending the cylinder 28b, respectively (FIG. 2).

Each transverse muscle Ry is bound on the longitudinal muscles Rx, Rx,..., Each intersection with the longitudinal muscles Rx, Rx,. Further, the binding direction of the binding portions Wa, Wa... On the horizontal stripe Ry is the reverse direction for each vertical stripe Rx. Therefore, for example, the intersections between the odd-numbered vertical bars Rx and the horizontal bars Ry can be bound together by the binding devices 12, 12... In the rear row, and the intersections between the even-numbered vertical bars Rx and the horizontal bars Ry. Can be bundled at once by the bundling machines 12, 12... In the front row (see FIG. 3).

  Prior to unloading from the manufacturing apparatus, each binding portion Wa of the reinforcing bar net RN can be deformed by bending the protruding portion below the vertical bar Rx and above the horizontal bar Ry along the reinforcing bar net RN. Preferably, it is preferable to provide an attachment therefor in the manufacturing apparatus. When the substantial thickness of the reinforcing bar net RN is reduced and the reinforcing bar net RN is embedded in the concrete, the effective thickness of the concrete can be increased.

  Prior to starting the flowchart of FIG. 12, a series of preparation steps are completed. That is, the guides 11, 11,... For the vertical bars Rx, Rx,... Are arranged according to the pitch Px, and the rear row binding machines 12, 12,. 12 corresponds to the even-numbered guides 11, 11,... (FIG. 3). Further, the front row binding machines 12, 12,... Are set to the back-and-forth direction spacing D> Py with respect to the rear row binding machines 12, 12,. Each guide 11 is individually moved to the left and right to achieve the pitch Px, and each binding machine 12 in the rear row and the front row is set to move the slide base 14 to the left and right to correspond to the specific guide 11. Further, the front row binding machines 12, 12... Are set so that the moving frame 33 is moved back and forth, and set at a distance D from the rear row binding machines 12, 12.

  Further, each binding machine 12 stands by by shortening both the lifting cylinder 12c and the swing cylinder 12d (see the rear row binding machine 12 in FIG. 5 and the front row binding machine 12 in FIG. 1). Further, between each binding machine 12 and the reel W1, one wire W is suspended and stored via the roller 34 (two-dot chain line in FIG. 5), and the roller 34 is at the upper retracted position. Return it (solid line in the figure).

  A predetermined number of vertical stripes Rx, Rx,... Are aligned behind the reels W1, W1 for the binding machines 12, 12,. Let Thereafter, the rear ends of all the vertical bars Rx, Rx... Are pushed forward by a pusher (not shown) so that the vertical bars Rx, Rx. Further, the horizontal stripes Ry, Ry,... Are also supplied in order on the hooks 23a, 23a,. The reels W1, W1,... For the front row binding machines 12, 12,... Are held forward by gripping the front end of the semi-finished product of the reinforcing bar net RN that advances along the upper edges of the guide plates 15f, 15f. In order to pull it out, a puller device (not shown) is kept waiting.

  When the above preparatory steps are completed, the longitudinal bars Rx, Rx... Are simultaneously advanced along the guides 11, 11... Via the pushers at the rear ends of the longitudinal bars Rx, Rx... (Step (1) in FIG. Hereinafter, it is simply written as (1)). The front ends of the vertical bars Rx, Rx... Pass over the rear row binding machines 12, 12... And the position of the horizontal bars Ry set in advance on the vertical bars Rx, Rx. When N is reached (2), the pusher is stopped to stop the advancement of the vertical bars Rx, Rx... (3), and the transverse bars Ry are bound to the back row binding machines 12, 12. .. Are fed on the longitudinal bars Rx, Rx... Corresponding to the position N, and the binding machines 12, 12... In the rear row are operated simultaneously to bind the transverse stripes Ry onto the odd-numbered longitudinal bars Rx, Rx. Thereafter, the horizontal streak Ry bound on the odd-numbered vertical streaks Rx, Rx... Does not reach the binding position N of the front row binding machines 12, 12... (4), and the vertical streaks Rx, Rx. After confirming that the number of transverse stripes Ry, Ry... Are not bound (6), the process returns to step (1) to continue the advancement of the longitudinal stripes Rx, Rx.

  Subsequently, when the horizontal streak Ry bound by the rear row binding machines 12, 12... Reaches the binding position N of the front row binding machines 12, 12,... (4), the vertical bars Rx, Rx. 5) The front row binding machines 12, 12... Are operated all at once to bind the horizontal stripes Ry on the even-numbered vertical stripes Rx, Rx. Thereafter, the same operation may be repeated until the predetermined number of horizontal stripes Ry, Ry... Are tied on the vertical stripes Rx, Rx... ((6), (1) to (6)).

  As described above, while the longitudinal bars Rx, Rx,... Are intermittently advanced, the binding devices 12, 12,... Of each row are operated so that the lateral stripes Ry, Ry, ... are moved from the front ends of the longitudinal bars Rx, Rx,. When the bundles are sequentially bound, the semi-finished product of the reinforcing bar net RN advances on the guide plates 15f, 15f,. Therefore, the front end of the reinforcing bar net RN is gripped by a puller device (not shown) and the pusher that pushes the rear end of the vertical bars Rx, Rx... Is retracted backward, and thereafter the reinforcing bar net RN, the vertical bars Rx, Rx. Move forward.

  The operation of each binding machine 12 in the rear row is generally as shown in FIG. That is, when the longitudinal muscle Rx is advanced along the guide 11 and the mounting position of the transverse muscle Ry set to the longitudinal muscle Rx reaches the binding position N of the binding machine 12 in the rear row (FIG. 13A), the longitudinal muscle Rx is changed. The horizontal streak Ry is supplied onto the vertical streak Rx at the binding position N by the transfer devices 20 and 20. Therefore, the left and right pushers 27, 27 are temporarily actuated to center the transverse stripe Ry (FIG. 13B), and the clampers 28, 28 are actuated to restrain the transverse stripe Ry on the longitudinal stripe Rx (FIG. 13 ( B).

  Subsequently, the elevating cylinder 12c is extended to raise the binding machine 12 (FIG. 13C), and the intersection of the vertical bars Rx and the horizontal bars Ry is inserted between the hook 12a and the curl guide 12b of the binding machine 12. To do. After that, the swing cylinder 12d is extended to erect the binding machine 12 (FIG. 13D), and the binding machine 12 is operated to bind the intersection using the binding wire W. At this time, the wire W suspended and stored below the drawing roller 34 is drawn out to the binding machine 12 through the guide wheel 15 and the wire guide 12e, and moves high under the roller 34 (FIG. 13 ( D) Dash-dot line). Therefore, by extending the clamping cylinder 15c and restraining the wire W on the guide wheel 15, the pulling roller 34 is lowered (two-dot chain line in FIG. 13D), thereby guiding the roller 35. Then, the wire W is fed out from the reel W1, and the wire W having a predetermined length is stored again below the roller 34.

  After the bundling operation, the bundling machine 12 shortens the swing cylinder 12d and shortens the lifting cylinder 12c to return to the original position in FIG. 13A. Release restraint. Further, the roller 34 is returned to the upper retracted position immediately after being lowered for feeding the wire W, and the clamping cylinder 15c releases the restraint of the wire W.

  The operation of each binding machine 12 in the front row is roughly as shown in FIG. That is, when the longitudinal streak Rx advances and the transverse streak Ry bound on the longitudinal streak Rx by the back row binding machine 12 reaches the binding position N of the front row binding machine 12 (FIG. 14A), the vertical streak Rx is Stop and extend the elevating cylinder 12c to raise the binding machine 12 (FIG. 14B), and insert the intersection of the vertical streak Rx and the horizontal streak Ry between the hook 12a and the curl guide 12b of the binding machine 12. To do. Thereafter, the swing cylinder 12d is extended to bring the binding machine 12 upright (FIG. 14C), and the binding machine 12 is operated to bind the intersection.

  At this time, the wire W stored below the drawing roller 34 is consumed by the binding machine 12. Accordingly, the clamping cylinder 15c and the roller 34 are used to feed out the wire W from the reel W1 and store it again below the roller 34, thereby shortening the swing cylinder 12d and shortening the lifting cylinder 12c. Returning the binding machine 12 to the original position in FIG. 14A and releasing the restraint of the wire W by the clamping cylinder 15c are exactly the same as in the binding machine 12 in the rear row. 14A to 14C, the upper edge of the guide plate 15 f in front of each binding machine 12 in the front row supports the horizontal stripe Ry on the vertical stripe Rx from the guide 11. The height is set as follows.

  In the above description, the rear row and front row binding machines 12, 12... May be m units and (m−1) units, respectively, and the guides 11, 11. . However, m is an arbitrary integer.
