[Prior art]

 For example, steel ingots that have undergone the manufacturing process of rolled steel that is formed by sequentially passing steel ingots through multiple rolling rolls to form bar steel with a cross-sectional shape according to the application, such as bar steel and shaped steel, and other steel pipes are grouped in the required number of units. The bundles are bundled together by a twisting wire and the like, and the bundled units are supplied to a straightening device for straightening the bend imparted during rolling. That is, the bundle is transferred to the collecting line immediately before entering the straightening device, and the bundle is released (unbundled) on the line, and many steel materials are aggregated in the vertical and horizontal directions. Be transported. In the present specification, a steel material or a long rod-shaped member which is remarkably long compared to the size of its cross section, such as the above-mentioned bar steel or steel pipe, is referred to as a “rod-shaped material”.

[0003]

[Problems to be solved by the device]

 The large number of rod-shaped materials conveyed in the agglomerated state need to be passed one by one through the roll of the straightening device installed downstream in order to straighten the bending imparted during rolling. For this reason, conventionally, a skid-type shooter is attached to the downstream side of the conveyor, and a cylinder-driven stopper is driven up and down to feed material to the straightening device. However, in the conventional device, it is difficult to reliably separate one rod-shaped material from the large number of rod-shaped materials that arrive in the agglomerated state, which requires a complicated manual operation by the operator's visual observation. .

Further, since the operation is uncertain, a plurality of rod-shaped materials are simultaneously supplied to the roll of the straightening device, which often causes a roll damage accident due to biting. In this case, since the surface of the straightening roll is hardened, it is difficult to repair damage caused by the sticking of the rod-shaped material, and during that time, the operation of the straightening device must be stopped. This resulted in a decrease in efficiency and large economic loss.

There is. Further, the second regulation disc 37 is rotated a required number of times when the bar-shaped material 11 which has passed through the position where the first regulation disc 36 is arranged and is divided is blocked by the third regulation disc 38 in the standby state. At this time, vertical vibration is applied to the rod-shaped material group to function to loosen the entanglement of the rod-shaped material group. That is, when entanglement occurs in the divided rod-shaped material group, the entanglement of the rod-shaped material 11 is eliminated by applying vibration to each rod-shaped material 11 by the second regulation disk 37. Further, the third regulating disk 38 functions to stop the divided rod-shaped material group in order to apply vibration to the rod-shaped material group by the second regulating disk 37. Instead of the third regulating disk 38, a stopper that can be retracted from the upper surface of the guide 39 by driving a cylinder or the like may be provided.

[Operation of the embodiment]

 Next, the operation of the automatic material feeding device provided with the rod-shaped material feeding device according to the embodiment will be described. Prior to the operation of the apparatus, as shown in FIG. 1, the first moving bed 42 and the second moving bed 54 in the stopped state in the first feeding apparatus 40 and the second feeding apparatus 52 are It is moved and adjusted with respect to the fixed bed 53, and the space between the moving beds 42, 54 and the fixed beds 41, 53 is adjusted according to the diameter of the rod-shaped material 11 (see FIG. 3). That is, when separating the rod-shaped material 11 having a required size, the moving beds 42 and 54 are moved and adjusted in the front-rear direction according to the diameter thereof. As described later, the moving floors 42, 54 ascend the plurality of rod-shaped materials 11 that reach the stepped portion 43 of the first fixed floor 41 and the serrated protrusions 55 of the second fixed floor 53, as will be described later. When pushing up, the distance is adjusted so that only one rod-shaped material 11 can be lifted.

As shown by the solid line in FIG. 1, the binding bundle of the rod-shaped material 11 bound by the numbering wire or the like is placed on the three holding devices 14, 15, 16 and at the same time as the first sorting station. It is placed on the second most upstream conveyor 21. When the bundle of bundles placed on the second conveyor 21 is cut and unbunched, the rod-shaped material group collapses and the upstream blocking plate 28 that faces the third position in the upstream first dividing device 25 Wait for material supply in a blocked state. By lowering the upstream blocking plate 28 from the third position to the second position, the rod-shaped material group moves over the blocking plate 28 to the downstream side and is blocked by the stopper 31. Next, the upstream dam plate 28 is moved up to the third position by the cylinder 30, so that the vertical thickness of the rod-shaped material group placed on the dam plate 28 becomes thin. In this state, by moving the downstream blocking plate 28 upward by the cylinder 30 to the second position where it projects from the transport surface, the required number of blocks that are blocked by the stopper 31 and face above the blocking plate 28 are provided. The rod-shaped material 11 is washed away to the downstream side and transferred onto the transfer surface of the second conveyor 21. Therefore, by moving the second conveyor 21, the required number of rod-shaped materials 11 divided by the downstream blocking plate 28 are conveyed toward the second dividing station. At this time, the rod-shaped material 11 on the upstream side is prevented from moving by the upstream and downstream dam plates 28, 28 and the stopper 31.

The rod-shaped material 11 conveyed by the second conveyor 21 is transferred onto the guide 39 of the second sorting station and slides down, and the leading end thereof is the first regulation disc 36 of the second sorting device 32.

Move to the downstream side. Then, the first control disk 36 again projects to the upper surface of the guide 39 to prevent the subsequent movement of the rod-shaped material 11, thereby further requiring the rod-shaped material group divided by the first dividing device 26. It is divided according to the number. As shown in FIG. 4B, the rod-shaped material 11 slid down along the guide 39 is prevented from moving by the third regulating disc 38 and is retained above the second regulating disc 37. At this time, by rotating the second regulation disk 37 a required number of times, vertical vibration is applied to the rod-shaped material group, and the entanglement of each rod-shaped material 11 is released. Next, as shown in FIG. 4 (c), the third regulating disk 38 is rotated counterclockwise, so that the disk 38 is retracted from the upper surface of the guide 39, and the separated rod-shaped material group is guided. Along 39, it slides down to the lowest step 43 of the first fixed bed 41 in the first feeder 40 (see FIG. 5 (a)).

At the timing when the rod-shaped material 11 is supplied to the lowermost step 43 of the first fixed bed 41 in the first supply device 40, the cylinder 47 is biased in the forward and reverse directions, and the first moving bed 42 is moved. It is reciprocally driven with a required stroke up and down. At this time, as described above, the space between the step portion 45 of the first moving bed 42 and the step portion 43 of the first fixed bed 41 is adjusted according to the diameter of the rod-shaped material 11 to be supplied (FIG. 3). reference). Therefore, when the first moving bed 42 moves diagonally upward to a level above the step 43 of the first fixed bed 41, as shown in FIG. The part 45 surely captures only one rod-shaped material 11 and transfers it to the next step 43 of the first fixed bed 41. By repeating the diagonal reciprocating motion of the first moving bed 42 up and down, the rod-shaped material 11 divided into a required number at the second dividing station is conveyed through the apparatus according to the present invention. The rod-shaped material 11 is separated one by one. Finally, as shown in FIG. 5 (c), it is supplied from the uppermost step 43 of the first fixed bed 41 to the serrated projection 55 of the starting end of the second fixed bed 53 of the second feeder 52. It

Here, in the first supply device 40, since the first fixed bed 41 and the first moving bed 42 are formed stepwise, the rod-shaped material 11 is sequentially operated under the cooperative action of both floors 41, 42. It is placed on the upper step 43. Therefore, even if a mistake occurs in lifting the rod-shaped material 11 due to the step portion 45 of the first moving bed 42, the rod-shaped material 11 always drops downward, so that the plurality of rod-shaped materials 11 are moved to the upper step portion 43. It can be effectively prevented from being supplied. If the two rod-shaped materials 11 are supplied to the uppermost step portion 43 of the first fixed bed 41 in a state of being vertically overlapped with each other, the detection means detects this and the ejection device 48 of the ejection device 48 is detected. The cylinder 51 is urged, and as shown in FIG. 6, the repelling member 50 rotates in the clockwise direction, and the bar-shaped material 11 on the upper stage is repelled. As a result, the rod-shaped material 11 is supplied from the first supply device 40 to the second supply device 52 one by one.

Next, at the timing when the rod-shaped material 11 is charged into the saw-toothed projections 55 at the starting end portion of the second fixed bed 53 of the second supply device 52, the cylinder 57 is alternately biased in the forward and reverse directions. As a result, the second moving bed 54 is reciprocally driven up and down with a required stroke. At this time, as in the case of the first feeding device 40, when the second moving bed 54 moves diagonally upward to a level higher than the serrated projection 55 of the second fixed bed 53, the second moving bed 54 moves. The serrations 56 on the floor 54 ensure that only one bar 11 is captured and transferred to the next serration 55 on the second fixed bed 53. The rod-shaped material 11 is surely supplied downstream one by one by repeating the up and down diagonal reciprocating motion of the second moving bed 54. That is, even if the plurality of rod-shaped materials 11 are supplied from the first supply device 40 to the second supply device 52, the second supply device 52 separates them one by one.

The rod-shaped materials 11 transferred one by one by the cooperation of the second moving bed 54 and the second fixed bed 53 are further transferred downstream by the independent moving bed 58 that is independently reciprocally driven. . Finally, only the rod-shaped material 11 supported by the serrated protrusions 55 at the terminal end of the second fixed bed 53 is transferred to the supply roller 61 by the independent moving bed 58 and supplied to the straightening device. To be done.

If the rod-shaped material 11 is not supported by the saw-toothed projections 55 of the second fixed floor 53 corresponding to the independent moving bed 58, the material supply is interrupted in the normal operation. Therefore, in this case, the single moving bed 58 on the upstream side of the serrated protrusions 55 not supported by the rod-shaped material 11 is independently moved upward to supply the rod-shaped material 11 to the empty serrated protrusions 55 and supply it. The supply of the rod-shaped material 11 to the roller 61 can be prevented from being interrupted.

When the rod-shaped material group supplied to the upstream portion of the first sorting station is exhausted by repeating the above-mentioned steps, the rod-shaped material group held in the holding device 16 on the downstream side passes through the first conveyor 12. And is conveyed to the second conveyor 21. That is, the first support body 17a is swung downward from the transport surface of the first conveyor 12 by the urging force of the first cylinder 19 of the holding device 16, and the second support body 17b is urged by the urging force of the second cylinder 20. Is rotated downward from the transport surface of the first conveyor 12, and the rod-shaped material group placed and held on the holding means 17 is transferred to the transport surface of the first conveyor 12. The first conveyor 12 is driven for the time for transferring the rod-shaped material group of the holding device 16 to the second conveyor 21, and the rod-shaped material 11 transferred to the second conveyor 21 is downstream as in the case described above. Be transported to the side. Then, when the rod-shaped material 11 held in the holding device 16 on the downstream side is completely supplied, the holding of the rod-shaped material 11 held in the holding devices 15 and 14 is sequentially released and supplied.

[About another embodiment]

 FIG. 7 shows another embodiment, in which a bundle of rod-shaped materials 11 supplied from the previous step is conveyed downstream by a conveyor 65 in which attachments 64 are arranged at predetermined intervals in the traveling direction of the endless chain 63. It is supposed to do. On the downstream side of the conveyor 65, a separation / supply device 69 in which a chain 66 is bridged between a pair of rollers 67 and 68 is arranged. In this separating / supplying device 69, the rod-shaped material group conveyed by the conveyor 65 is held by a chain 66 which is faced in a loose state between both rollers 67 and 68, and then tension is given to the chain 66. Thus, the chain 66 is stretched between the rollers 67 and 68, and the rod-shaped material 11 is sent to the downstream side.

A guide 70 is inclinedly arranged on the downstream side of the separating and supplying device 69, and the rod-shaped material 11 transferred to the guide 70 is supplied to the first supplying device 40 on the downstream side. The first supply device 40 basically requires the same configuration as that of the above-described embodiment, but in the other embodiment, the steps 43 and 45 in the first fixed bed 41 and the first moving bed 42 are used. By increasing the number of stages, it is possible to achieve good and reliable separation. Further, the first moving bed 42 is configured to be vertically reciprocated by an eccentric disk 71 that is rotationally driven by a motor or the like.

A roll 72 extending a required length in the material conveying direction is rotatably arranged on the downstream side of the first feeding device 40, and the diameter of the rod-shaped material 11 is provided on the outer periphery of the roll 72. A larger spiral groove 72a is formed. That is, when the rod-shaped material 11 is supplied from the first supply device 40 to the roll 72 rotated by a motor (not shown), the material 11 is axially moved along the spiral groove 72a. Then, the rod-shaped material 11 released from the roll 72 is supplied to the second supply device 52 including the second fixed bed 53 and the second moving bed 54, and the supply roller of the straightening device is supplied via the second supply device 52. One is supplied to each 6 1. The second moving bed 54 of another embodiment is rotatably supported at its downstream end, and is configured to swing up and down via a link rod 73 by a driving means (not shown). .

In this alternative embodiment also, a large number of rod-shaped materials 11 supplied from the separation / supply device 69 can be separated one by one by the first supply device 40 and supplied downstream. Then, finally, the rod-shaped material 11 is supplied one by one to the supply roller 61 of the straightening device, and a roll damage accident due to a plurality of rod-shaped materials 11 being simultaneously supplied to the rolls of the straightening device is prevented beforehand. can do.
