Description

  The present invention relates to a shaping device that bundles and shapes a plurality of materials to be shaped, and a bundling device including the shaping device.

  When shipping a long round steel material (shaped material) such as a round steel bar or a round steel pipe, the round steel material is bundled into a bundle of a plurality of units so that it can be handled easily. In addition, when a good packing after bundling is required, a plurality of round steel materials can be shaped in advance into a required shape by a shaping device having a pair of crossing arms before bundling the plurality of round steel materials. (For example, refer to Patent Document 1). As shown in FIG. 9, the conventional shaping device has a pair of crossing arms 13 on a base 12 disposed below a transfer level L of the round steel material 10 by a horizontal roller 11 that transfers the round steel material 10 along the longitudinal direction. , 14 are rotatably arranged. In FIG. 9, the upper end of the first crossing arm 13 located on the right side is located on the upper right side of the transfer region S of the round steel material group transferred by the horizontal roller 11 in the standby posture shown in FIG. Yes. One end of the first chain 15 is connected to the upper end of the first crossing arm 13 and the other end of the first chain 15 is connected to the base 12 on the lower left side of the transfer region S. . Then, in the standby state shown in FIG. 9A, the first chain 15 is held in a state where it hangs in an inverted substantially L shape from the upper end portion of the first intersection arm 13.

  Further, the second crossover arm 14 located on the left side in FIG. 9 is configured to be bilaterally symmetrical with the first crossover arm 13, and the upper end of the second crossover arm 14 is shown in FIG. 9 (a). In the standby posture, it is located on the upper left side of the transfer area S. One end of the second chain 16 is connected to the upper end of the second crossing arm 14, and the other end of the second chain 16 is connected to the base 12 on the lower right side of the transfer region S. And the 2nd chain 16 is hold | maintained at the state which hung down in the substantially L shape from the upper end part of the 2nd intersection arm 14 in the standby state shown to Fig.9 (a). In addition, the 1st crossing arm 13 and the 2nd crossing arm 14 are spaced apart and back and forth in the transfer direction of the round steel material 10, and as shown in FIG. It is configured to be able to cross over the transfer area S.

  As a packing form of the round steel material bundle in which the plurality of round steel materials 10 are bundled, each round steel material 10 is bundled as densely as possible (so as to eliminate a gap between the steel materials), and is advantageous in terms of space for transportation or storage, and There is a demand for each round steel material to have a stable circular shape without being easily moved after binding.

  In the shaping device, the other ends of both the chains 15 and 16 are connected to the base 12 below the transfer level L by the horizontal roller 11, so that the upper ends of both the crossing arms 13 and 14 intersect. In the case of rotation, as shown in FIG. 9B, the chains 15 and 16 move from the upper side to the lower side so that one end of the chains 15 and 16 approaches the other end. For this reason, the plurality of round steel materials 10 shaped into a bundle having a predetermined shape by the both chains 15 and 16 are shaped in a state of being placed on the horizontal roller 11. For this reason, the lower end part of a round steel material group does not round, but the cross section of the shaped round steel material group will become a substantially triangular shape. Therefore, even if a round steel material group shaped by a conventional shaping device is bound by a binding machine, the round steel material group does not have a circular cross section, and is bound in a substantially triangular shape. That is, in the current situation, the conventional shaping device cannot meet the demand for a round steel material bundle having a circular cross section. Moreover, in a round steel material bundle having a substantially triangular cross section, each round steel material 10 easily moves during transportation and the like, causing a problem that the package shape changes and is disadvantageous for transportation and storage.

  Further, when the round steel material group that is shaped while being placed on the horizontal roller 11 is bound with a wire or the like, when the wire wound around the round steel material group is twisted upward or laterally, If the round steel material group is biased in the left-right direction or separated from the side, the length of the left and right extending parts extending from the twisted position in the wire toward the round steel material group may be different, It will be longer than necessary. Even if the binding tool is twisted in this state, the twisting of the binding tool is incomplete, and the binding is completed in a state where the binding tool is not in close contact with the round steel material group. There is a problem that the packaging changes due to the occurrence of.

The first sprocket 33 and the second sprocket 45 can be moved to a position where they are to be moved. That is, to the position where the winding part of the second roller chain 47 in the second sprocket 45 faces the right side with respect to the winding part of the first roller chain 35 in the first sprocket 33 moved to the operating position by the first cylinder 32. The second sprocket 45 is set to move by the second cylinder 44. The first cylinder 32 and the second cylinder 44 are configured to always urge the piston rods 32a and 44a in a direction to be drawn at a predetermined pressure when shaping the round steel material group. That is, when the number of round steel materials 10 to be shaped is changed, the corresponding moving bodies 31 and 43 are moved to the operating positions corresponding to the number of the round steel materials 10.

  As shown in FIG. 6, the first roller chain 35 and the second roller chain 47 are assembled with the pin 51 and the link plate 52 constituting the roller chain 35, 47 loosely fitted to the pin 51. A curved chain is used in which the pivotally supported roller 53 is bent in the extending direction of the pin 51 (longitudinal direction of the round steel material 10) with respect to the link plate 52 and can move three-dimensionally. Further, the roller 53 is set to have a diameter protruding from the link plate 52, and when the round steel material group is shaped, the roller 53 is brought into contact with the round steel material 10 to prevent the round steel material 10 from being damaged. It is configured to do.

  Steel columns sensors (sensors) 54 capable of detecting a state in which the round steel material 10 is spaced upward from the lower surface level PL (the transfer surface L of the horizontal roller 18) of the shaping region PS are provided on the support columns 23, 23 of the apparatus body 25. It is arranged. As the steel material sensor 54, a photoelectric sensor in which a light emitting element and a light receiving element are arranged to face each other with the shaping region PS interposed therebetween is suitably used. The pair of roller chains 35 and 47 is used to raise the round steel material 10 to a predetermined height. It is set so that the light from the light-emitting element is received by the light-receiving element and the detection signal is output to the control means when it is lifted only by the height. The steel sensor 54 is arranged on the upstream side and the downstream side in the transfer direction of the support columns 23 and 23 (see FIG. 5), and is configured to detect the round steel material 10 lifted by the roller chains 35 and 47 at two locations. It is.

(Effects of Example)
Next, the operation of the shaping device and the bundling device according to the above-described embodiment will be described.

  As shown in FIG. 1, the first moving body 31 and the second moving body 43 stand by at their respective standby positions, and the first roller chain 35 and the second roller chain 47 surround the shaping area PS. It is assumed that it hangs down from the upper stay 24 in a substantially U shape. At this time, each first detection sensor 39 detects a corresponding first weight 37 facing the retreat position, and each second detection sensor detects a corresponding second weight 49 facing the retreat position.

  By the rotation of the horizontal roller 18 and the side rollers 19, 19, the plurality of round steel materials 10 placed on the transfer surface L of the horizontal roller 18 are transferred in the transfer region S in a stacked state, and each shaping device 17 passes through the shaping area PS and the area defined by the pair of roller chains 35 and 47. Then, when the planned binding site of the round steel material group arrives at the binding position (shaping region PS) by the binding machine 20, the rotation of the rollers 18, 19, 19 stops and the transfer of the round steel material group stops. At this time, a group of round steel materials faces the wire guide 56 in the binding machine 20. In the shaping device 17, the first cylinder 32 and the second cylinder 44 are biased in the direction in which the piston rods 32a, 44a are pulled into the barrel, and as shown in FIG. The second moving body 43 moves to the right from the standby position.

  As the first moving body 31 moves to the left, the first sprocket 33 around which the first roller chain 35 is wound moves to the left while rotating, so that the first roller chain 35 The right side 35b moves to the left while being gradually pulled up. On the other hand, as the second moving body 43 moves to the right, the second sprocket 45 around which the second roller chain 47 is wound moves to the right while rotating, so that the second roller The left side 47b of the chain 47 moves to the right while being gradually pulled up. That is, the round steel material 10 positioned on the right side of the round steel material group is moved toward the center by the leftward movement of the right side portion 35b of the first roller chain 35, and the round steel material is moved by the rightward movement of the left side portion 47b of the second roller chain 47. The round steel material 10 positioned on the left side of the group is moved to the center, and the right side portion 35b and the left side portion 47b intersect with each other above the round steel material group, so that the round steel material group is shaped so that the upper side approaches the center. At this time, as shown in FIG. 7, the length from the portion wound around the first sprocket 33 of the first roller chain 35 to the portion connected to the first fixing portion 34 becomes short, and the second roller The length from the part wound around the second sprocket 45 of the chain 47 to the part connected to the second fixing part 46 is shortened, so that the round steel material group has the lower surface level PL (in the relevant area) of the shaping region PS. It is lifted from the transfer surfaces L) of the horizontal rollers 18 and 18 positioned before and after the shaping device 17 and shaped so that the lower side of the group of round steel members is rounded, and shaped so that the cross section approaches a substantially circular bundle. The

  Here, when shaping the front end side or the rear end side of the long round steel material 10, even if the round steel material 10 is pulled up from the lower surface level PL of the shaping region PS at a portion (shaping position) corresponding to the shaping device 17, The rear end side or the front end side of the round steel material 10 remains placed on the transfer surface L of the horizontal roller 18 that is spaced upstream or downstream from the shaping device 17. Therefore, the round steel material 10 in the shaping position pulled up from the lower surface level PL of the shaping region PS is vertically or horizontally with respect to the rear end side or front end side of the round steel material 10 that is in contact with the transfer surface L of the horizontal roller 18. It will tilt. In this case, since the curved chain is adopted as the first roller chain 35 and the second roller chain 47, when the round steel material 10 is tilted, the chain itself in contact with the round steel material 10 follows to follow the round steel material. By shifting in the longitudinal direction of 10, the chains 35 and 47 are not twisted and an excessive load is not applied to the roller chains 35 and 47, and the roller chains 35 and 47 can be prevented from being damaged. Further, since the rollers 53 constituting the roller chains 35 and 47 are configured to protrude from the link plate 52, only the roller 53 comes into contact with the round steel material 10 and the link plate 52 does not come into contact with the round steel material 10. Will not hurt.

  When the steel material sensor 54 detects that the round steel material group has been pulled up from the lower surface level PL of the shaping region PS, the control means stops urging the first cylinder 32 and the second cylinder 44, and the first moving body 31. The second moving body 43 is held in the operating position. In this state, the round steel material group shaped by the shaping device 17 is bound by the binding machine 20. That is, the binding tool 21 supplied to the wire guide 56 is wound around the round steel material group shaped by the shaping device 17 and formed into a loop shape, and the rear end side of the binding tool 21 is supplied by the drawing means. By pulling back to the source side, the binding tool 21 is narrowed down with respect to the round steel material group. After cutting the rear end side of the binding tool 21 with a cutter, the binding device 21 is twisted on the upper side of the round steel material group by rotating the clamp device 57 that clamps the front end and the rear end of the binding tool 21, By further narrowing down the binding tool 21, the round steel material group is bound by the binding tool 21.

  When bundling by the bundling machine 20, the round steel material group shaped and held by the shaping device 17 is from the lower surface level PL of the shaping region PS, that is, from the transfer surfaces L of the horizontal rollers 18 and 18 positioned before and after the shaping device 17. When the binding tool 21 is squeezed by the squeezing means, and when the binding tool 21 is further squeezed by the clamping device 57, the round steel members 10 are substantially spaced from each other by squeezing the binding tool 21. It moves easily so as to form a circle which is a dense state without any gaps. Further, the entire round steel material group also moves toward the position where the slack does not occur when the binding tool 21 is twisted by the clamp device 57 with the clearance being reduced with respect to the round steel material group by narrowing down the binding tool 21. The bundling tool 21 can bind in a state in which the package shape after binding does not change. That is, the package of the round steel material group bound by the binding tool 21 is in a state in which the cross-section is substantially circular and the binding tool 21 is in close contact without slack.

  For example, when the bundling tool 21 is clamped and bound above the round steel material group as in the embodiment, the entire round steel material group that is shaped while being placed on the horizontal roller as in the past is clamped by the clamp device 57. If it deviates in the left-right direction with respect to the position, the lengths of the left and right extending portions extending from the clamp position in the binding tool 21 toward the round steel material group will be different. Even if the clamping device 57 is rotated and the binding tool 21 is twisted in this state, the binding is completed when the short extending portion is twisted, and the portion that is not twisted in the long extending portion. Remains, which causes slack. However, in the configuration in which the round steel material group is shaped in a lifted state by the shaping device 17 as in the embodiment, even if the round steel material group at the time of shaping is biased left and right with respect to the clamp position, the binding tool 21 Since the entire round steel material group moves toward the vertical center line passing through the clamp position by narrowing down, the lengths of the left and right extending portions of the binding tool 21 extending from the clamp position toward the round steel material group are approximately equal. Will be equal. Therefore, when the binding device 21 is twisted by rotating the clamping device 57, the left and right extending portions are evenly twisted so that the binding device 21 is in close contact with the round steel material group and is not loosened. Groups can be united.

  The steel material sensor 54 detects that the round steel material group has been lifted by a predetermined height from the lower surface level PL of the shaping region PS, and the urging of the first cylinder 32 and the second cylinder 44 is stopped. It is possible to prevent the round steel material group from being lifted more than necessary. That is, only the shaping part in the shaping device 17 in the round steel material group is greatly lifted with respect to the transfer surface L of the horizontal roller 18, thereby preventing the long round steel material 10 from being deformed.

  After the binding by the binding machine 20, the first cylinder 32 and the second cylinder 44 are urged so as to extend the piston rods 32a, 44a, and the first moving body 31 and the second moving body 43 are set to the standby position. Moving. As the first moving body 31 and the second moving body 43 move, the first sprocket 33 and the second sprocket 45 rotate while moving, and thereby the first roller chain 35 and the second roller chain 47 are lowered, A group of round steel materials suspended by both roller chains 35 and 47 is placed on the transfer surface L of the horizontal rollers 18 and 18. Therefore, the transfer by rotation of the horizontal roller 18 and the side rollers 19 and 19 becomes possible.

  Here, when the round steel material group is placed on the transfer surface L of the horizontal roller 18, the pulling force due to the weight of the round steel material group applied to both roller chains 35 and 47 is eliminated, so that the roller chains 35 and 47 are There is a risk of not being in a normal standby state. However, in the embodiment, since the first weights 37, 37 are arranged on the left side 35 a and the right side 35 b of the first roller chain 35, Each of the right side portions 35b that hang down moves so as to hang down substantially vertically. Similarly, since the second weights 49, 49 are provided on the right side 47 a and the left side 47 b of the second roller chain 47, the right side 47 a hanging from the second fixing portion 46 and the left side hanging from the second sprocket 45. Each of the parts 47b moves so as to hang down substantially vertically. At this time, the lower support portions 35c and 47c of the roller chains 35 and 47 are placed on the corresponding support bases 40 and 50 as shown in FIG. Therefore, both roller chains 35 and 47 are in a normal standby state surrounding the shaping area PS, and are prevented from interfering with the round steel material group transferred through the shaping area PS. If the roller chains 35 and 47 are in the normal standby state, the first weight 37 and the second weight 49 are in contact with the positioning member 38 in the standby position, so that the roller chains 35 and 47 in the standby state On the other hand, the load of the weights 37 and 49 is not applied.

  Further, since the detection sensor 39 detects that the first weight 37 and the second weight 49 are in contact with the corresponding positioning members 38, the roller chains 35 and 47 are not in a normal standby state. In such a case, the round steel material group interferes with the roller chains 35 and 47 by not issuing an alarm by an alarm means such as a lamp or a buzzer or by not driving the horizontal roller 18 and the side rollers 19 and 19. Can be prevented in advance.

  As described above, after the detection sensor 39 detects the corresponding weights 37 and 49 and it is confirmed that the two roller chains 35 and 47 are in the normal standby state, the horizontal roller 18 and the side rollers 19 and 19 are detected. Is rotated again to transfer the group of round steel materials to the downstream side. Then, when the next binding scheduled portion arrives at the binding position (shaping region PS) of the binding machine 20, after the rollers 18, 19, 19 are stopped, the round steel material group is shaped by the shaping device 17 as described above. At the same time, binding is performed by the binding machine 20. Thereafter, by repeating the steps of transferring, shaping, and bundling the round steel material group in the same manner, the round steel material group has a package shape in which a plurality of portions in the longitudinal direction are bound by the binding tool 21 and the cross section is substantially circular. That is, it is advantageous in terms of space during transportation or storage, and a round steel material bundle having a stable load shape can be obtained without easily moving each round steel material 10 after binding.

[Example of change]
The present application is not limited to the configuration of the above-described embodiment, and other configurations can be appropriately employed.
1. The cable body is not limited to the one whose other end is connected to the mounting member, but the other end is connected (connected) to the connecting member, and the connecting member is obliquely upward from the standby position toward the fixed portion arrangement side. By configuring to move, it is possible to adopt a configuration in which the cord body is moved leftward or rightward while being pulled up. That is, the other end of the cable body whose one end is connected to the fixing portion may be connected to an appropriate fixing portion or may be connected to a connecting member, and the connecting member can be moved forward and backward from the standby position. Along with this, the portion that hangs down from the connecting member moves to the fixed member, and the hanging end portion may be configured to move up and down.
2. In the embodiment, when shaping the round steel material group, the winding portion (left side of the shaft) of the first roller chain in the first sprocket is moved to the left side from the center position in the width direction in the shaping region, and the second sprocket in the second sprocket is moved. Round steel material group by moving the winding part of the two-roller chain (right side from the shaft) to the right side from the center position in the width direction in the shaping area to the right side part of the first roller chain and the left side part of the second roller chain However, the present invention is not limited to this. That is, the roller chain winding part of the other sprocket moves to a position beyond the roller chain winding part of one sprocket that has moved to the operating position, so that both roller chains can cross over the round steel material group. That's fine.
3. The cable body is not limited to the roller chain, and any other cable can be used as long as it has a predetermined flexibility such as a wire or a belt. However, a roller chain is preferable in terms of strength and durability. In addition, what is necessary is just to change about a connection member to a roller, a pulley, etc. according to the wire, belt, etc. which are employ | adopted as a rope. Further, the connecting member is not limited to the rotating member, and the cord body may slide along with the movement of the connecting member.
4). The connecting member is not limited to the configuration provided in the moving body, and may be directly connected to the operating means and moved by the operating means.
5. The moving body operating means is not limited to a cylinder, and means for moving the moving body by operating a linkage mechanism such as a chain-sprocket or rack-pinion with a motor can be employed.
6). The moving body is not limited to a configuration in which the moving body is movably mounted on the guide rail via a wheel, but the moving body has a width such as a configuration in which the moving body is slidably disposed on the guide rail via a slider. Other configurations can be appropriately employed as long as the configurations can move in the direction.
7). The transfer means for transferring the round steel material is not limited to one constituted by a plurality of horizontal rollers, and may be configured so that the round steel material can be transferred in a state where the hanging lower end portion of the rope body in the shaping device faces below the transfer means. That's fine. For example, an appropriate conveyor such as a belt conveyor or a slat conveyor may be arranged before and after the transfer direction across the shaping device. The side rollers prevent the group of round steel materials transferred by the horizontal rollers from falling off to the side, and can be replaced by a freely rotating or non-rotating guide bar.
8). In the embodiment, the case where the shaping device is arranged on the binding line in which the round steel material is transferred by the transfer means has been described, but the arrangement location of the shaping device is not limited to this. For example, you may be comprised so that a round steel material group may be supplied to the shaping area | region of a shaping apparatus with a suitable supply means. In this case, support means for supporting the round steel material group is disposed on both sides before and after the shaping region in the shaping device, and the round steel material group facing between the two support means is shaped using a pair of cords. Also good.

When shaping the round steel material group with the shaping device, it is configured to apply vibration to the round steel material group from the outside with vibration applying means such as a cylinder so that the round steel material group can be gathered into a more circular cross section. Good. Further, the round steel material group can be gathered into a more circular shape by vibrating the roller chain itself or the connecting member.
10. In the embodiment, the binding tool is twisted on the upper side of the round steel material group in the binding machine, but the binding tool may be twisted on the lateral side of the round steel material group. Even in this case, since the round steel material group is shaped and held by the shaping device in a state of floating from the support means, each round steel material is easily moved to a dense circular state by tightening the binding tool, and the round steel material group Is moved so as to be close to the clamp position, and the tying member is bound without slack. That is, even if the round steel material group shaped by the shaping device is separated from the clamp position, the round steel material group moves toward the clamp position by narrowing the binding tool, and the binding tool is rotated by the rotation of the clamping device. Is twisted without slack.
11. When the binding tool is tightened by the binding machine, vibration may be applied to the round steel material group from the outside by vibration applying means such as a cylinder so as to promote the movement of each round steel material.
12 The material to be shaped is not limited to a round steel material, but may be other materials such as a long material made of synthetic resin.
