Description

  The present invention relates to a wire ring conveying device that conveys a wire ring that is spirally expanded after rolling on a conveyor, and in particular, keeps the dropping posture horizontal when the wire ring falls and forms it at a coil forming unit. The present invention relates to a wire ring conveying device capable of improving the packing state of a coil to be used.

Conventionally, in a wire ring conveying device in which a coil forming unit is continuously provided on the downstream side, a method of aligning the conveyed wire ring or a wire ring is dropped and accumulated in the coil forming unit in order to adjust the packing state of the coil. When this is done, a method of keeping the dropping posture of the wire ring horizontal has been studied.
For example, (Patent Document 1) states that “a step with a lower converging device side is provided during the transport step, and the apex is located at the center side in the transport width direction at the position where both ends of the spiral wire rod in the width direction are placed in the step. A wire rod conveying device characterized in that a pair of cantilevered conical rollers facing each other is provided.
Also, when the conveyed wire ring is dropped and focused on the coil forming part, the chain ring or ski plate-like skid wound around multiple sprockets is placed above the conveyor to keep the dropping position of the wire ring horizontal.

It has a problem that it cannot be maintained, is easily decentered in the front-rear direction, and lacks reliability.
(2) When the wire ring is pressed from above by a chain wound around multiple sprockets, the wire ring is likely to get caught in the gap between the sprocket and the chain, and the operation is not stable. In the case of sandwiching the device, there is a problem that it is necessary to stop the apparatus and lack reliability. Moreover, since it is a fixed type, it has the subject that it cannot respond to the change of the thickness by the case where the wire diameters of a wire rod differ, or the difference in the overlapping condition of wires, and lacks versatility.
(3) Those that press the wire ring from above by skid are in surface contact and have high contact resistance with the wire ring, so that the surface of the wire ring is scratched and the quality is liable to deteriorate and lack in reliability. It had the problem that. Further, the wire ring is liable to be displaced in the front-rear direction due to frictional resistance, and the inner and outer diameters of the coil are not uniform, making packing and transportation difficult, resulting in poor handling.

  The present invention was made in order to solve the above problems, and by pressing the wire ring by point contact, it has excellent transport stability without causing catching, misalignment, scratches, etc. during transport of the wire ring, When the wire ring is dropped and focused on the coil forming part, the dropping posture of the wire ring can be kept horizontal, the inside and outside diameters of the entire formed coil can be made uniform, and packing and transportation can be facilitated.

As the fixing means, one that locks the wheel 5a, one that fixes the support base 3a and the base 5 by pin fitting, screwing, or the like is preferably used.
Next, the swinging member 9 is swung by expanding and contracting the expansion / contraction mechanism 14b, and the distance between the lower end of the presser disk 11 and the upper surface of the conveyor 2 is adjusted according to the wire diameter of the wire rod 20 and the overlapping state of the wires. To do.

In FIG. 4, the wire ring 20 conveyed by the conveyor 2 is pressed by the presser disk 11. Since the wire ring 20 is conveyed while being spirally overlapped, it is possible to press the rear end side of the downstream wire ring 20 only by pressing a part of the upstream wire ring 20. Since the rear end side (upstream side) of the wire ring 20 is pressed until just before dropping to the coil forming part 17, the dropping posture can be kept substantially horizontal, and the displacement of the wire ring 20 in the front-rear direction can be prevented. .
Further, the downstream side of the conveying roller 16 is tilted upward by expanding and contracting the tilt driving unit 16i. Since the feeding angle of the wire rod ring 20 can be adjusted, the falling posture of the wire rod ring 20 can be reliably kept horizontal regardless of the ring diameter or feed speed of the wire rod ring 20.

As described above, the wire ring transport device according to Embodiment 1 has the following effects.
(1) The rear end side of the wire ring 20 until the wire ring 20 is dropped by the wire ring presser mechanism 4 having the presser disk 11 that presses the wire ring 20 conveyed on the conveyor 2 from above. , The dropping posture of the wire ring 20 can be kept substantially horizontal, and the inner diameter and outer diameter of the entire coil formed by the coil forming portion 17 on the downstream side can be made uniform so that the packing state of the coil can be obtained. Can be improved.
(2) Since the wire ring 20 can be pressed by the outer peripheral surface of the presser disc 11, the wire ring 20 is not caught or scratched, and the conveyance and quality stability are excellent.
(3) The presser disk 11 is inserted and fixed to the rotary shaft 10 disposed orthogonal to the conveying direction of the conveyor 2, and the rotary shaft drive unit 12 is connected to the rotary shaft 10 via the drive transmission members 12a and 12b. Therefore, the rotating shaft 10 can be rotated in synchronization with the conveying speed of the conveyor 2, and the contact resistance between the presser disk 11 and the wire ring 20 can be reduced. Is less likely to occur, and the packing state of the coil formed by the coil forming portion 17 can be improved.
(4) Since the pressing height adjusting unit 6 that moves the rotary shaft 10 in the vertical direction is provided, the distance between the lower end of the presser disk 11 and the upper surface of the conveyor 2 can be adjusted by moving the rotary shaft 10 up and down. When the wire diameter of the ring 20 is different, or changes in thickness due to the difference in the degree of overlap between the wires, it is possible to cope with a change in thickness. In particular, with respect to several rings on the front end side and the rear end side of the wire ring 20, the pressing force for pressing the wire ring 20 is weakened by widening the gap between the lower end of the presser disk 11 and the upper surface of the conveyor 2. Transport can be performed smoothly.
(5) The pressing height adjusting unit 6 has a swinging member 9 which is pivotally supported at one end side so as to be swingable on the swinging center shaft 8 and rotatably supports the rotary shaft 10 at the other end side. The moving member drive unit 12 can swing the swinging member 9 about the swinging center shaft 8, and the distance between the lower end of the presser disk 11 and the upper surface of the conveyor 2 can be easily adjusted, and the workability is excellent.
(6) Since the swing member 9 is provided with the adjustment weight portion 13 connected via the extending portion 13a on the opposite side of the rotation shaft 10 across the swing center shaft 8, the wire rod 20 is pressed. The pressing force to be adjusted can be easily adjusted, and the handleability is excellent.
(7) Since the swing lever 14a is pivotally supported by the swing center shaft 8 and is in contact with the lower surface of the contact portion 9b of the swing member 9, the rotating member 9 is moved by the telescopic mechanism 14b. Since it can be supported from below, the rotating member 9 can be rotated simply by expanding and contracting the expansion / contraction mechanism 14b, and the pressing height of the presser disk 11 can be easily adjusted.
(8) Since the rotation member 9 and the adjustment weight portion 13 are connected to each other with the rotation center shaft 8 interposed therebetween, the load applied to the expansion / contraction mechanism 14b can be reduced, so that the rotation can be easily performed with a small force. The rotating operation of the moving member 9 can be performed, and the labor saving is excellent.
(9) The member opening drive portion 15 connected to the adjustment weight portion 13 via the extending portion 13a can be expanded and contracted with a small force to pull down the adjustment weight portion 13, and the rotation center shaft 8 can be quickly moved. The rotating member 9 is rotated around the center to raise the presser disk 9, and when the supply of the wire ring 20 starts and ends, the leading end and the last end of the wire ring 20 are opened and dropped to the coil forming portion 17. Can be made.
(10) Since the wire ring presser mechanism 4 is slidably disposed in parallel with the conveying direction of the conveyor 2, the presser position by the presser disc 11 can be adjusted by moving the wire ring presser mechanism 4 back and forth. Even when the ring diameter and the feed speed of the wire rod ring 20 are different, the optimum position can be pressed and the dropping posture of the wire rod ring 20 can be kept horizontal.
(11) Since the wire ring presser mechanism 4 is slidably disposed, the wire ring presser mechanism 4 can be retracted backward for maintenance when a problem occurs in the coil forming portion 17.
(12) Since the tilt drive unit 16i that tilts the downstream end of the transport roller 16 provided downstream of the conveyor 2 upward is provided, the tip end side of the wire ring 20 is tilted upward and sent out. It is possible to prevent the positional deviation in the front-rear direction of the coil forming portion 17 by keeping the posture of the wire ring 20 horizontal just before dropping to the coil forming portion 17 on the downstream side.
(13) Since the tilt drive unit 16i that tilts the downstream end of the transport roller 16 upward is provided, the feed angle of the wire ring 20 can be easily adjusted, and the ring diameter of the wire ring 20 The drop posture of the wire ring 20 can be reliably kept horizontal regardless of the feed rate and feed rate.
