[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a round bar binding and conveying device for binding round bars into parallel bundles by a round bar binding machine.

[0002]

[Prior art]

 Generally, as a bundling / conveying device for round bars, as shown in FIG. 5, a molding machine 2 and a horizontal roller 3 that conveys the round bars 9 to be bundled and a molding machine 2 and a fixed vertical roller 4 on both sides are combined. It is known that the binding machine 1 is arranged. The round bar 9 is conveyed by rotating the horizontal roller 3 and is guided by the fixed vertical rollers 4 on both sides so as not to drop from the horizontal roller 3, and the tip binding portion of the round bar 9 is positioned at the position of the binding machine 1. When it becomes, stop the transportation. Next, as shown in FIG. 5 (a), the crossing arms provided in the plurality of molding machines 2 are tightened to bundle the round bars 9 in parallel, and the molding wire 10 is supplied from the binding machine 1. Tie round bar 9.

Subsequently, when the tail end binding portion of the round bar 9 is conveyed to the position of the binding machine 1, the crossing arm of the molding machine 2 is opened again, and then the horizontal roller 3 is rotated to rotate the round bar 9. The tail end binding section is conveyed until it reaches the position of the binding machine 1 and stopped. At this time, as shown in FIG. 5 (b), the tip end of the round bar 9 is bound by the forming wire 10 so that the shape of the load can be maintained, but the tail end of the round bar 9 is a fixed vertical roller. It spreads to part 4. For this reason, there is a problem in that the crossing arms of the molding machine 2 are tightened and the packing shape is adjusted so that the round bars 9 are parallel to each other.

As described above, when a round bar is bound by a binding machine, a conventional U-type conveyor is used to prevent the tail ends from spreading and it is difficult to bind them in a parallel state, or the binding machine is made movable. It is known to adjust the width of the vertical roller in the roller table including the horizontal roller and the vertical roller.

[0005]

[Problems to be solved by the device]

 However, when a bundle of round bars is conveyed by the U-shaped conveyor, the width of the tail end of the round bars that bundles only the tip can be prevented to some extent, but it is not sufficient and there is a drawback that it cannot handle bundles of various sizes. is there. In addition, if the binding machine is a mobile type, a parallel binding bundle of round bars can be obtained, but there is a problem that the equipment becomes large and the capital investment amount becomes too high.

In the method of adjusting the width of the vertical roller of the roller table, when the vertical roller is simply shifted by a cylinder or the like, a round bar bundle of various sizes cannot be supported, and if the bundle is small, the spread of the bundle cannot be prevented. , If the bundle is large, improper conveyance will occur due to the pressing force. In addition, if the system is adjusted to a desired position by adjusting the width with gears, auxiliary equipment such as a drive system and a system to determine the stop position is required, resulting in a high investment amount.

An object of the present invention is to provide a bundling / conveying device for round bars, which can solve the above-mentioned problems of the prior art by a simple equipment improvement.

[0008]

[Means for Solving the Problems]

 The present invention to achieve the above object is to bind and convey a round rod in which a molding machine and a binding machine are arranged on a line of a roller table in which a horizontal roller for conveying a round rod to be bound and vertical rollers on both sides are combined. In the apparatus, the vertical roller arranged on either one of the vertical rollers on both sides is provided with a shift mechanism in the width direction provided with a drive source of a weak shift force, and the shift mechanism is allowed to move forward. A lock mechanism that can lock the reverse shift is provided, and after the tip ends of the round bars are bound using the molding machine and the bundling machine, the vertical roller on the one side is vertically rolled to a position equivalent to the width of the round bar bundle. The tail end of the round bar bundle with the leading end tied to the tail end of the round bar bundle while it is being conveyed on the roller table to bind the binding part. Unity Widthwise spread of the a forming bundle conveying device round bar, characterized by being configured to receive the vertical rolls locked through a lock mechanism provided in the shift mechanism.

[0009]

[Action]

 In the present invention, in the mechanism for shifting the vertical roller of the roller table, the driving source such as the cylinder is set to have a weak force enough to shift the vertical roller, and the bundle of round bars is pressed more than necessary to cause the conveyance failure. On the other hand, the lock mechanism of the vertical roller prevents the spread of the round bar bundle.

Further, the drive source such as a cylinder for shifting the vertical roller and the lock mechanism of the vertical roller can shift the vertical roller to a width suitable for the bundle of round bars, thereby suppressing the spread of the tail end of the round bar. After binding the ends of the round bars, the tail ends do not spread even during the transportation for binding the tail ends, and it is possible to carry parallel bundles of round bars. As a result, it is possible to bind the round bars from the tip to the tail as a parallel bundle.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the device of the present invention, as shown in FIGS. 1 to 3, one of the vertical rollers arranged on both sides of the roller table is a movable vertical roller 5 and the other is a fixed vertical roller 4. Other configurations are the same as those of the conventional device shown in FIG. 5, and the round bar delivered by the horizontal roller 3 is guided by the fixed vertical roller 4 and the movable vertical roller arranged on both sides, The forming machine 2 and the binding machine 1 arranged on the line of the roller table are used to bind the round bars.

The movable vertical roller 5 according to the present invention is provided with a support block 12 at a lower portion thereof, and the support block 12 is set to be shiftable in a groove of a shift guide 8. A lock claw 7 is attached to the support block 12 and a shift cylinder 6 is connected to the support block 12. Inside the shift guide 8, a concave-convex stopper 13 that engages with the lock claw 7 is provided in a range excluding both ends in the longitudinal direction. The lock claw 7 rotates about the pin as a fulcrum, and the shift vertical cylinder 6 is used to allow the forward vertical shift of the movable vertical roller 5 toward the fixed roller 4 side and lock the backward shift. The shift mechanism engages with the concave-convex stopper 13. The lock claw 7 can be unlocked at both ends without the stopper 13.

Next, the operation of the device of the present invention will be described with reference to FIG. 4. FIG. 4A shows a cross-sectional state of the initial round bar 9 conveyed on the horizontal roller 3, and at this time, Since the movable vertical roller 5 has been unlocked by the lock claw 7, the movable vertical roller 5 is pushed by the round bar 9 to a position corresponding to the fixed vertical roller 4, and the round bar 9 is in a horizontal position on the horizontal roller 3. It keeps spreading. 4B shows a state in which the round bar 9 is bundled with the forming wire 11 using the bundling machine 1 after the round bar 9 is clamped by the crossing arm of the molding machine 2 in order to bind the tip end of the round bar 9. Shows.

After the tip portion of the round bar 9 is bound with the forming wire 11 in this way, the shift cylinder 6 is actuated to bind the movable vertical roller 5 as shown in FIG. 4C. When the vertical roller 5 is moved to the position of the bundle of rods, the vertical roller 5 is shifted by the shift cylinder 6 having a weak shift force, so that the vertical roller 5 stops in a state of hitting the bundle of round rods 9. Next, when the crossing arm of the molding machine 2 is opened for transporting the tail end binding portion of the round bar 9 to the position of the binding machine 1, the bundle of round bars 9 is widened as shown in FIG. 4 (a). I try to spread in the direction.

However, the lock mechanism of the movable vertical roller 5, that is, the lock claw 7 attached to the support member 12 is locked by the concave-convex stopper 13 formed in the shift guide 8, and the vertical roller 5 moves in the width direction. It is prevented from spreading. For this reason, as shown in FIG. 4C, the horizontal rods 3 can be moved on the horizontal roller 3 until the tail end binding portion of the round rods 9 reaches the position of the binding machine 1 while holding the round rods 9 in the bundled posture. .

Thus, when the tail end binding portion of the round bar 9 reaches the position of the binding machine 1, the horizontal roller 3 is stopped, and then the binding machine 1 is operated with the round bar 9 tightened using the molding machine 2. Then, the tail end binding portion of the round bar 9 held in the horizontal state can be bound by the forming wire 11. After bundling the tip and tail ends of the round bar 9 in this manner, the horizontal roller 3 is rotated and carried out, and then the shift cylinder 6 is operated to move the vertical cylinder 5 as shown in FIG. 4 (d). Is moved forward to shift to the closing limit where the concave and convex stopper 13 is not provided, and then the lock of the lock claw 7 is released. Then, when the shift cylinder 6 is actuated again and the vertical cylinder 5 is retracted, the unlocked lock claw 7 is not locked by the stopper 13 and the support block 12 moves along the shift guide 8. Return to the lock open state shown in 4 (a).

Although the lock mechanism having a simple structure has been described in the above embodiment, the present invention is not limited to this, and a lock mechanism such as a brake system can be used.
