Description

  The present invention relates to a bar steel material bundle number separating device that divides a bar steel material conveyed from an upstream side into a predetermined number before binding steel bar materials such as reinforcing steel bars and round steel bars.

  Manufacture and shipment of steel bars such as steel bars and round bars are performed as follows. A steel strip (billet) is hot-rolled to form a long material having a total length of about 80 to 120 m, and after cooling the long material, it is cut into predetermined lengths (for example, 8 m), Steel bars are used. And these bar steel materials are bundled for every predetermined number, and are shipped (for example, refer patent document 1).

On the upstream side of the apparatus for binding the steel bars, a steel bar bundle number separating device (hereinafter referred to as a separating device) is installed, and this separating device divides the steel bars conveyed from the upstream side by a predetermined number. It has a function.
FIG. 11 is a side view of the preceding separator 81 provided in the separator, and FIG. 12 is a side view of the sequential separator 82 provided in the separator. Only one of the preceding separators 81 is installed on one end side in the longitudinal direction of the steel bar W conveyed by the conveyor 80, and the separators 82 are sequentially aligned with the preceding separator 81 in the longitudinal direction of the steel bar W. Multiple units are provided.

  In FIG. 11, the steel bars W can be counted by the sensor 84 detecting one end of each steel bar W fitted in the groove of the sprocket 83 while the conveyor 80 conveys the steel bars W. A regulation plate 85 having a convex curved surface is provided on the downstream side in the conveyance direction of the sprocket 83, and the bar steel material W that has been conveyed and counted by the conveyor 80 cannot get over the regulation plate 85, and is on the conveyor 80. It stays at. When the bar steel W is counted for a predetermined number, the first leading pawl member 86 provided in the leading separator 81 is activated (arrow G1 in FIG. 11), and the leading pawl member 86 has been counted. In addition, the staying steel bar W is scooped up and conveyed to the top of the regulation plate 85. The conveyed steel bar W is received by the second preceding claw member 87, and when the preceding claw member 87 operates (arrow G2 in FIG. 11), the steel bar W slides down the regulation plate 85, and the conveyor 80 Return to the top.

  In the sequential separator 82 shown in FIG. 12, the first sequential claw member 88 is actuated, and the bar steel material W that has been counted and stays in the leading claw member 86 of the preceding separator 81 (see FIG. 11). Together with scooping up (arrow G3 in FIG. 12), these steel bars W are conveyed to the top of the regulating plate 89. The conveyed steel bar W is received by the second sequential claw member 90, and when this sequential claw member 90 is operated (arrow G4 in FIG. 12), the steel bar W slides down the regulation plate 89, and the conveyor 80 Return to the top.

  In this way, the predetermined number of steel bars W counted are separated from the steel bars W before counting on the upstream side. By repeatedly performing this separation operation, the steel bars W are divided into a predetermined number, and the predetermined number of steel bars W are bound into one bundle by a downstream binding machine.

  As described above, according to the preceding separator 81 and the sequential separator 82, the bar steel materials W can be separated by a predetermined number. When scooping up along the restricting plates 85 and 89 and when dropping over the restrictor plates 85 and 89 onto the conveyor 80, the steel bars W may cross each other to generate a twill.

If the twill is generated in the steel bar W, it is bound as it is, and is shipped after being stored in a warehouse. In this way, the steel bars are bundled in a state where the twill is generated, and when other bundles are stacked or transported in the bundle, the steel bars are bent and the straight stretchability is poor. As a result, the commercial value is reduced.
In addition, at the shipping destination, the work is taken out one by one after the bundle is unwound, but if a tread occurs in the bar steel material, the bar steel material and the other steel bars crossing the bar steel material The work of taking out the steel bar becomes difficult, requiring time and work efficiency.

  Therefore, an object of the present invention is to provide a bar steel material bundle number separating device that suppresses crossing of bar steel materials when the bar steel materials are divided into a predetermined number before binding the steel bars.

  The present invention is a conveyor capable of transporting a plurality of steel bars in a state perpendicular to the longitudinal direction of the steel bars, a counter for counting the steel bars conveyed by the conveyor, A stopper that restricts the movement of a predetermined number of the steel bars that have been counted and are transported by the conveyor to the downstream side in the transport direction, and a predetermined number of the steel bars that are restricted by the stopper in the transport direction And a separator having a mounting member placed in an aligned state and a moving mechanism for moving the mounting member. The moving mechanism moves the mounting member to a predetermined A number of the steel bars are moved in the aligned state to the downstream side in the transport direction beyond the stopper, and the steel bars are returned to the conveyor in the aligned state.

  According to this steel bar bundle number separating device, the moving mechanism moves the mounting member so that the predetermined number of steel bars and the steel bars before counting are counted on the downstream side and the upstream side in the conveying direction. Can be separated. Further, in this separation, a predetermined number of steel bars are placed on the mounting member in an aligned state in a line in the conveying direction, and these steel bars are returned to the conveyor in the aligned state. Crossing each other can be suppressed.

Further, the separator includes a preceding separator that is provided on one end side of the bar steel material and moves a predetermined number of the bar steel materials counted by the counter in advance by the moving mechanism; and A plurality of the steel bars are provided in the longitudinal direction along with the preceding separator, and when the movement of the steel bar is started by the preceding separator, the steel bars by the moving mechanism in order toward the other end side of the steel bar. And a sequential separator that starts the movement of
According to this configuration, when the preceding separator separates one end portion of the predetermined number of steel bars that have been counted from the steel bar before counting, the plurality of sequential separators separate the steel bars from the steel bars. It can isolate | separate with the steel bar material before a count in order toward an edge part side. For this reason, separation of the counted bar steel material and the bar steel material before counting is performed reliably. In this case, an operation of separating a predetermined number of the steel bars from the one before the counting from the one end to the other end is performed.

Further, the steel bar bundle separation device is provided together with each of the sequential separators, and when it is lifted, the steel bar can be lifted and separated from the conveyor, and the transport can be temporarily stopped. It further comprises a skid capable of resuming the conveyance of the bar steel material, the upper surface of the skid is flat, and a predetermined number of the bar steel material that has been counted by moving the mounting member and the bar steel material before the counting It is preferable that the steel bar is slid on the upper surface of the skid.
As described above, the operation of separating a predetermined number of steel bars from the one end side toward the other end side is performed in order from the bar steel material before counting. When it is forcibly moved to the downstream side in the transport direction, the other end side tends to move upstream by reaction. Therefore, according to the skid, the other end side of the counted steel bar material to be moved to the upstream side, and further, the steel bar material before measurement on the upstream side can slide along the upper surface of the skid. It is possible to prevent a portion of the bar steel material that has been counted from overlapping with the bar steel material before counting.

  ADVANTAGE OF THE INVENTION According to this invention, when separating the predetermined number of bar steel materials and the bar steel material before a count, it can suppress that steel bars cross. As a result, when a predetermined number of separated steel bars are bound, twill is less likely to occur.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing a schematic configuration of a steel bar bundle number separating device 1. This steel bar bundle number separating device 1 (hereinafter referred to as “separating device 1”) is installed on the upstream side of a binding machine (not shown) that binds a plurality of steel bars W into a single bundle. The bar steel material W is provided with a function of dividing it into a predetermined number. The steel bar W is a reinforced steel bar or a round steel bar.

  The separating apparatus 1 divides the steel bar W into a predetermined number while conveying a plurality of steel bars W by the conveyors 11 and 71. In each figure, the conveyance direction of the steel bar W is indicated by an arrow X. In the following, the conveying direction of the steel bar W by the conveyor 11 is simply referred to as “conveying direction”.

  In FIG. 2, the counter 12 counts the number included in the bundle of steel bars W to be bound by the binding machine (not shown). The counter 12 of the present embodiment includes a sprocket 15 and a sensor 16, and the sensor 16 counts one end portion Wa of each steel bar W fitted in the groove of the sprocket 15 while the conveyor 11 a transports the steel bar W. To do. Thereby, the counter 12 can count the bar steel material W conveyed by the conveyor 11a. When a part (one end Wa) of the bar steel material W is fitted in the groove of the sprocket 15, the adjacent bar steel materials W are transported at intervals. For this reason, the steel bar W can be accurately detected by the sensor 16, and the counting accuracy can be increased.

  The stopper 13 is provided downstream of the sprocket 15 and along the conveyor 11b. As shown in FIG. 2, the stopper 13 has an inclined portion 14 a that is gradually higher than the conveying surface from a position lower than the conveying surface (upper surface) of the conveyor 11, and the steel bar W further from the inclined portion 14 a. And a convex portion 14b which is higher than the diameter. According to this stopper 13, the predetermined number of steel bars W that have been counted by the counter 12 and are transported by the conveyor 11b are placed on the inclined portion 14a and the top steel bar W hits the convex portion 14b. The movement of the predetermined number of steel bars W to the downstream side in the conveying direction is restricted. Furthermore, according to the stopper 13, it is possible to restrict a predetermined number of steel bars W from moving downstream in an aligned state in a line in the transport direction.

The mounting member 21, the moving base 41 and the pair of arms 43 form a parallelogram. A link mechanism is configured. For this reason, the mounting member 21 can be moved up and down while the upper surface of the mounting member 21 (the upper surface 23a of the main body 23) is maintained in a horizontal posture. A movable head 44 a of the telescopic actuator 44 is attached to one of the pair of arms 43, and a main body 44 b of the telescopic actuator 44 is attached to the second moving base 42.

Further, as the telescopic actuator 44 extends (returns), the mounting member 21 transports the stopper 13 as shown in FIG. 5 by translating the second moving base 42 downstream in the transport direction. The steel bar W on the mounting member 21 is placed on the conveyor 11b by reaching the position where the upper surface 23a of the main body portion 23 is lower than the conveying surface of the conveyor 11. Passed.

As described above, when the moving mechanism 22 moves the mounting member 21, the predetermined number of steel bars W whose movement is restricted by the stopper 13 are arranged in a line in the conveying direction in the conveying direction. The steel bar W can be moved downstream beyond the stopper 13 and returned to the conveyor 11b in the aligned state.
As will be described later, the movement of the entire predetermined number of steel bars W toward the downstream side in the conveying direction will be described later, by cooperation with the sequential separator 30 of the sequential mechanism unit 3 that starts operation later than the preceding separator 20.

Further, the sequential mechanism unit 3 includes a skid 77. As described above, all the ten sequential mechanism units 3 (3-1 to 3-10) have the same configuration.
As shown in FIG. 1, the conveyor 71 includes an upstream first conveyor 71 a and a downstream second conveyor 71 b, and is the same as the conveyor 11 of the preceding mechanism unit 2. The conveyor 71 can be transported in a state in which a plurality of steel bars W are aligned in a direction (arrow X direction) perpendicular to the longitudinal direction of the steel bars W in cooperation with the conveyor 11 of the preceding mechanism section 2. is there.

  The stopper 73 is provided along the conveyor 71b at the same position as the stopper 13 of the preceding mechanism unit 2 in the transport direction. As shown in FIG. 6, the stopper 73 has an inclined portion 74 a that is gradually higher than the conveying surface from a position lower than the conveying surface (upper surface) of the conveyor 71, and further the steel bar W from the inclined portion 74 a. And a convex portion 74b which is higher than the diameter. According to this stopper 73, a predetermined number of steel bars W that have been counted by the counter 12 of the preceding mechanism section 2 (see FIG. 2) and are transported by the conveyor 71b are placed on the inclined section 74a and the leading bar. When the steel material W hits the convex portion 74b, the movement of the predetermined number of bar steel materials W to the downstream side in the transport direction is restricted. Furthermore, according to the stopper 73, it is possible to restrict a predetermined number of steel bars W from moving downstream in an aligned state in a line in the transport direction.

  The sequential separator 30 includes a mounting member 31 on which the steel bar W is placed, and a moving mechanism 32 that moves the mounting member 31. The mounting member 31 has a main body 33 having a horizontal upper surface 33a and a long length in the transport direction, and a claw portion 34 provided at an upstream end of the main body 33 in the transport direction. A predetermined number of steel bars W that have been counted and whose movement is restricted by the stopper 73 are arranged in a line in the transport direction on the upper surface 33a of the main body 33 on the downstream side of the claw part 34 in the transport direction. Can be placed in a state.

The moving mechanism 32 has the same configuration as the moving mechanism 22 of the preceding mechanism unit 2 (see FIG. 2), and includes a first moving base 41 and a pair of arms 43 attached to the moving base 41. The mounting member 31, the moving base 41, and the pair of arms 43 constitute a parallelogram link mechanism. For this reason, the mounting member 21 can be moved up and down while the upper surface of the mounting member 31 (the upper surface 33a of the main body 33) is maintained in a horizontal posture. A movable head 44 a of the telescopic actuator 44 is attached to one of the pair of arms 43, and a main body 44 b of the telescopic actuator 44 is attached to the second moving base 42.
The moving mechanism 32 includes a fixed base 40 that guides the second moving base 42 so as to be reciprocally movable in the horizontal direction, and a drive unit 45 that includes a linear motor that reciprocates the second moving base 42. . Thereby, the mounting member 31 can be moved horizontally while maintaining the upper surface of the mounting member 31 (the upper surface 33a of the main body 33) in a horizontal posture.

In the state shown in FIG. 6, the main body portion 33 (the claw portion 34 and the upper surface 33 a) of the mounting member 31 is at a position lower than the transport surface (upper surface) of the conveyor 71, and the movement is further restricted by the stopper 73. It is located below the predetermined number of steel bars W.
When the telescopic actuator 44 is shortened from the state shown in FIG. 6, the upper surface 33 a of the main body 33 of the mounting member 31 is more than the transport surface (upper surface) of the conveyor 71 as shown in FIGS. 7 and 8. Also reach a higher position. Further, the telescopic actuator 44 is extended (returned), and the second moving base 42 is further translated in the downstream direction in the transport direction, so that the mounting member 31 has a stopper 73 as shown in FIG. The steel bar W on the mounting member 31 can be moved to the position on the conveyor 71b by reaching the position that has passed to the downstream side in the conveying direction and the upper surface 33b of the main body 33 reaching a position lower than the conveying surface of the conveyor 71. Passed to.

As described above, when the moving mechanism 32 moves the mounting member 31, a predetermined number of steel bars W whose movement is restricted by the stopper 73 are arranged in a line in the conveying direction in the aligned state in the conveying direction. While moving beyond the stopper 73 to the downstream side, the steel bars W can be returned to the conveyor 71b in the aligned state.
The predetermined number of steel bars W are moved in cooperation with the preceding separator 20 of the preceding mechanism unit 2 that starts the moving operation first.

  The skid 77 is provided with each separator 30 in sequence, and when lifted, the steel bar W can be lifted and separated from the conveyor 71a to temporarily stop the conveyance. Further, the skid 77 is allowed to descend so that the conveyance of the steel bar W by the conveyor 71a can be resumed. The function of the skid 77 will be described later.

The separation process of the steel bar W performed by the separation apparatus 1 configured as described above will be described.
As shown in FIG. 1, a plurality of steel bars W cut to a predetermined length (for example, 8 m) are conveyed by the conveyor 11a of the preceding mechanism unit 2 and the conveyor 71a of the mechanism units 3-1 to 3-10 sequentially. Is done.

  As shown in FIG. 2, in the preceding mechanism section 2, the conveyor 11 a conveys the steel bar W, and the sensor 16 detects one end Wa of each steel bar W that fits in the groove of the rotating sprocket 15, thereby counting. The machine 12 counts the steel bar W. A stopper 13 is provided on the downstream side of the sprocket 15, and the steel bar W that has been transported and counted by the conveyors 11 a and 11 b cannot get over the convex portion 14 b of the stopper 13, and thus is on the conveyors 11 a and 11 b. Stays in a single row.

  When the bar 12 is counted for a predetermined number (set value) by the counter 12, in the preceding separator 20, the actuator 44 of the moving mechanism 22 extends to raise the mounting member 21, and the predetermined number ( The 1st nail | claw part 24 is interrupted between the (nth) bar steel W and the (n + 1) th bar steel W adjacent to the upstream (refer FIG. 3). Further, the moving mechanism 22 is operated, and the mounting member 31 lifts the steel bar W from the head of the counting start to the predetermined number (n-th) steel bar W in a horizontal alignment state (see FIG. 4). Thereby, the group of a predetermined number (n pieces) of the steel bars W and the upstream group including the (n + 1) th bar steel W on the upstream side thereof can be started to be separated in the horizontal direction.

When the preceding separator 20 starts the separation operation, the sequential separators of the sequential mechanism unit 3-1 (see FIG. 1) located adjacent thereto are delayed from the start timing of the separation operation by the preceding separator 20. 30 operates.
It should be noted that the steel bar W, which has been transported and counted by the conveyors 71a and 71b before the sequential separator 30 (see FIG. 6) is operating, cannot get over the convex portion 74b of the stopper 73, and the conveyor It stays in a row on 71a, 71b. Further, in order to prevent the steel bar W before counting from being conveyed downstream (to the sprocket 15 of the preceding mechanism unit 2), the skid 77 is raised (see FIG. 7).

In the sequential separator 30 of the sequential mechanism unit 3-1, the actuator 44 of the moving mechanism 32 extends to raise the mounting member 31, and the predetermined number (nth) steel bar W and its upstream side The claw portion 34 is inserted between the adjacent (n + 1) th steel bar W (see FIG. 7). At this time, by a preceding separator 20 (see FIGS. 3, 4 and 5), a group of a predetermined number (n) of steel bars W and an upstream group including the adjacent steel bars W on the upstream side thereof Are separated in the horizontal direction on the one end Wa side, the claw 34 can be easily interrupted by the sequential separator 30 of the sequential mechanism section 3-1 shown in FIG.
Further, the moving mechanism 32 operates to lift the mounting member 31 with the predetermined number of steel bars W aligned in a horizontal row (see FIG. 8), and the predetermined number (n) of bars in the sequential separator 30 also. The group of steel materials W and the upstream group including the adjacent steel bar W on the upstream side can be separated in the horizontal direction.

  Further, when the sequential mechanism unit 3-1 starts the separation operation, the sequential mechanism unit 3-2 (FIG. 1) located adjacent to the sequential mechanism unit 3-1 is delayed from the start timing of the separation operation by the sequential mechanism unit 3-1. In the same manner, the sequential separator 30 of the third sequential mechanism unit 3-3 starts the same operation. If the sequential separators 30 of the thirteenth to tenth sequential mechanism units 3 (3-3 to 3-10) delay the operation start timings in order, similar operations are started. Thereby, the bar steel material W can expand the space | interval with the bar steel material W before a count in order toward the other end part Wb side from the one end part Wa side.

Then, as shown in FIG. 5, in the preceding mechanism unit 2, the moving mechanism 22 further operates the mounting member 21, the bar steel W on the mounting member 21 is placed on the conveyor 11 b, and a predetermined number of bar steel W Is transported to the downstream binding machine side.
Moreover, as shown in FIG. 9, in the mechanism part 3 (3-1 to 3-10) sequentially, the moving mechanism 32 operates the mounting member 31, respectively, and the bar steel W on the mounting member 31 is the conveyor 71b. The predetermined number of steel bars W are placed on the upper side and conveyed to the downstream binding machine side.
The operation in which the preceding mechanism unit 2 places a predetermined number of steel bars W on the conveyor 11b and the operation in which each mechanism unit 3-1 to 3-10 sequentially places a predetermined number of steel bars W on the conveyor 71b are: Done synchronously.

  In this way, the predetermined number of steel bars W counted are separated from the steel bars W before counting on the upstream side. By repeatedly performing this separation operation, the steel bars W are divided into a predetermined number, and the predetermined number of steel bars W are bound into one bundle by a downstream binding machine.

  In the present embodiment, as an operation for separating a predetermined number of steel bars W, a predetermined number of bars W are arranged in a line in the transport direction by the stoppers 13 and 73 in each of the preceding mechanism part 2 and the sequential mechanism part 3. In this state, the steel bars W are restricted from moving downstream in the conveying direction. In the preceding separator 20 and the sequential separator 30, the mounting members 21 and 31 are stoppers 13 and 73, respectively. A predetermined number of steel bars W whose movement is restricted by the above are placed on the upper surfaces 23a and 33a in an aligned state in a line in the transport direction, and further, the bar steel materials W are stoppered downstream in the transport direction in the aligned state. The steel bar W is moved over the conveyors 11b and 71b while being in the aligned state.

  For this reason, it is possible to separate a predetermined number of steel bars W that have been counted and a steel bar W before counting into a downstream side and an upstream side in the transport direction, and at the time of this separation, a predetermined number of bars Since the steel material W is returned to the conveyors 11b and 71b in the aligned state, it is possible to suppress the crossing of the steel bars W. As a result, when the predetermined number of separated steel bars W are bound, the twill is less likely to occur.

Moreover, in this embodiment, as shown in FIG. 1, as a separator which isolate | separates the steel bar W as mentioned above, the one preceding separator provided in the one end part Wa side of the steel bar W conveyed is shown. 20 and 10 sequential separators provided in the longitudinal direction of the steel bar W along with the preceding separator 20 toward the other end Wb side of the steel bar W (starting with the leading separator 20). 30.
The preceding separator 20 moves a predetermined number of steel bars W counted by the counter 12 in advance by the moving mechanism 22 (see FIGS. 2 to 5). And when each of the sequential separators 30 starts to move the bar steel material W by the preceding separator 20, the moving mechanism 32 (FIG. 6 to FIG. 6) sequentially thereafter toward the other end Wb side of the bar steel material W. 9), the movement of the steel bar W is started.

  According to this configuration, when the preceding separator 20 separates the one end Wa side of the predetermined number of bar steel materials W that have been counted from the bar steel material W before counting, the predetermined number of bar steel materials W are The separator 30 can be separated from the steel bar W before counting in order toward the other end Wb side of the steel bar W. For this reason, separation of the counted steel bar W and the bar steel W before counting is performed reliably.

And according to this structure, the operation | movement which isolate | separates the predetermined number of steel bars W from the steel bars W before a count in order toward the other end part Wb side from the one end part Wa side is performed. In this separation, the one end Wa side of the steel bar W that has been counted is forcibly moved to the downstream side in the transport direction, so that the other end Wb side tends to move upstream by the reaction. To do.
Therefore, in each sequential mechanism unit 3, the upper surface 78 of the skid 77 is positioned below the transport surface of the conveyor 11 a before the sequential separator 30 performs the separation operation. In conjunction with the separation operation, the skid 77 (see FIG. 6) rises.

Since the upper surface 78 of the skid 77 is flat, when the mounting member 31 is moved, the predetermined number of the steel bars W and the steel bars W before counting are separated from each other by the reaction. The upper surface 78 of the skid 77 can be slid on the steel bar W (the other end Wb side) that is about to move to the side.
According to the skid 77, the unmeasured steel bar W on the other end wb side of the counted steel bar W to be moved to the upstream side, and further on the upstream side, along the upper surface 78 of the skid 77. Thus, it is possible to prevent a part of the bar steel material W that has been counted from overlapping with the bar steel material W before the counting.

Further, the skid 77 (see FIG. 6) has the functions described below in addition to the above functions.
As described above, the skid 77 can be lifted to lift the bar W from the conveyor 71a and temporarily stop the conveyance, and by descending, the conveyance of the bar W by the conveyor 71a can be resumed. Therefore, when the counter 12 finishes counting a predetermined number of the steel bars W in the preceding mechanism unit 2, the sequential mechanism unit 3-1 on the side closer to the preceding mechanism unit 2 and the mechanism unit 3-10 sequentially. After the separation operation by the separator 30 is started and the state shown in FIG. 4 is reached, the skid 77 is lowered. Thereby, conveyance of the steel bar W once stopped is restarted, and counting of the next steel bar W can be started. The descending of the skid 77 of the sequential mechanism unit 3-1 can be started before the separation operation by the sequential separator 30 of the sequential mechanism unit 3-10 farther from the preceding mechanism unit 2 is started. This makes it possible to start counting the next steel bar W while performing the separation operation in the sequential mechanism portion (3-10) on the side farther from the preceding mechanism portion 2, thereby reducing the cycle time of the separation operation. It can be shortened.

Although the said embodiment demonstrated the case where the steel bar W (deformed bar steel) which is comparatively small diameter (D10-D13) was isolate | separated, the said separating apparatus 1 is the bar steel material W (deformed shape) of a large diameter (D16-D51). It is also possible to separate the steel bars).
FIG. 10 is a side view of the mechanism part 3 in the case of separating the steel bar W having a large diameter. Although not shown, the steel bar W is counted by the counter 12 of the preceding mechanism unit 2, and when the predetermined number is counted, the mounting member 31 is sequentially raised and moved downstream in the mechanism unit 3 and moved upstream. It is possible to separate the existing steel bar W before counting and the predetermined number of steel bars W present on the downstream side and counted.

  In the case of a large diameter steel bar W, the stopper 73 can be dispensed with sequentially in the mechanism portion 3. For this purpose, for example, the stopper 73 may be lowered below the conveying surface of the conveyor 71. For this reason, the raising amount of the mounting member 31 may be small.

  Further, the separation device 1 of the present invention is not limited to the illustrated form, and may be in another form within the scope of the present invention. In the embodiment shown in FIG. 1, the case where ten mechanism units 3 are sequentially installed has been described, but this number can be changed according to the length of the steel bar W.
