Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic wire rod setting device such as a header for setting wire rods of material into a heading machine such as a header.

Conventionally, the material supplied to the header is a long wire wound into a coil.
Since it is difficult to connect the end of one coiled wire to the tip of the next coiled wire,
Normally, when one coiled wire is set in a carrier and used up to the terminal, the worker stops the header, sets the next coiled wire in the carrier, and attaches the tip of that wire to the header. After that, the header is set on the correct feed roller, and then the header is restarted.

However, it is usually not possible to manufacture extremely long and large coiled wire rods due to manufacturing and transportation constraints, and for this reason, in the case of high-speed headers, one coiled wire rod can be used to connect two or more headers. It can only be operated for 3 hours, and therefore, workers have to perform the above-mentioned work many times a day, which is troublesome. The task of setting the header to the header is particularly difficult.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to automatically set the tip of the coiled wire to a supplied part such as a header, and to feed the coiled wire to the terminal. An object of the present invention is to provide an automatic wire rod setting device such as a header suitable for automating the supply of new wire rods when used.

Next, the operation of the above configuration will be explained. For example, a plurality of rotary carriers 15 are prepared and arranged on the floor near the pedestal 1, and the rotary carriers 15
A wire rod 1 wound into a coil on a mounting table 15b of
6 is placed in advance, and the tip of the wire 16 is held and held by the holding portion 18a of the clip 18, as shown in FIG. When all the wire rods 16 on the rotating carrier 15 placed on the mounting table 8 are consumed by the header and become empty, the empty rotating carrier 15
is lowered onto the floor near the pedestal 1 from the top of the mounting table 8 by a transport device such as a crane (not shown), and in its place, the rotary carrier 15 on which the wire rod 16 is set as described above is set on the mounting table 8 by the transport device. Ru. In this case, the transporting device may be operated manually, and the rotating carriers 15 on which the wire rods 16 are set are arranged on a conveyor and are transported to a predetermined position by the conveyor. 15 may be automatically transported from the conveyor to the mounting table 8. When the rotary carrier 15 is set on the mounting table 8 in this way, if the transport device is operated manually, the operator will manually operate it, or if the transport device is operated automatically, a set completion signal will be sent. The respective gear motors 10 start operating. and. gear motor 1
0 is rotated, the rotation of the output gear 12 is caused by the rotation of the gear 9
The rotary carrier 1 is transmitted to the movable ring 7a via the mounting table 8 and is set on the mounting table 8.
5 is rotated in the direction of arrow A, and when the extension part 17 is positioned directly above the position sensing sensor 20, the operation of the gear motor 10 is stopped by the output signal from the position sensing sensor 20. As a result, the tip of the wire rod 16 set in the clip 18 is directed toward the wire straightener 25. On the other hand, gear motor 10
During or immediately after the rotation, the hydraulic cylinder 13 is extended and the elevating body 4 is raised to the highest set position, so that the clip 18 is at the same height level as the wire straightener 25, the feed roller 33, and the wire supply pipe 22. becomes. Next, the operation of supplying the tip of the wire 16 from the rotary carrier 15 stopped at a fixed position to the wire supply pipe 22 of the header, which is the part to be supplied, will be described. For example, when the gear motor 36 is rotated in the direction of the arrow B, the drive shaft 35 is rotated in the direction of the arrow B, and the gears 44 and 45 are both rotated in the direction of the arrow B via the gear 46. On the other hand, the feed screws 42 and 43 are each provided with a right-hand thread, and when the feed screws 42 and 43 are rotated in the direction of the arrow B, the actuating arm 49 with the female threaded portion 49a meshing with the feed screw 42 is rotated as shown in the arrow. When the actuating arm 49 is horizontally moved in the E direction and the feed screw 42 is rotated in the arrow C direction, the actuating arm 49 is horizontally moved in the arrow D direction. The movement of these actuating arms 49, 50 is effected by moving the clutches 47, 48 toward and away from each other and by switching the rotation of the gear motor 36 in the direction of arrow B or in the direction of arrow C.

When the rotary carrier 15 is stopped at a fixed position, the operating arms 49 and 50 are in the vicinity of the gear 46, that is, in a position opposite to the tip of the wire 16 held by the clip 18, as shown in FIG. Waiting in a standing position. When the rotary carrier 15 is stopped at a certain position due to the operation of the position sensor 20, the chuck devices 51 and 52 are opened and the air cylinder 41 is extended so that the movable arm 40 moves the drive shaft 35. The actuating arms 49 and 50 are rotated in the direction of the arrow F about the drive shaft 35, and the actuating arms 49 and 50 are rotated in the direction of the arrow F about the drive shaft 35.
The tip of the wire 16 held by the clip 18 is positioned between the fixed claw 51a and the movable claw 51c and between the fixed claw 52a and the movable claw 52c. After this, the chuck device 51,5
Hydraulic cylinders 51b and 52b of 2 contract, respectively, and between the fixed claw 51a and the movable claw 51c and the fixed claw 5
Recesses 51d and 51e between 2a and movable claw 52c
When the wire rod 16 is gripped by 52d and 52c, the air cylinder 41 contracts and the movable frame 40 is rotated about the drive shaft 35 in the opposite direction of the arrow F.
Along with this, the operating arms 49 and 50 are raised as shown in FIG. 1, and at the same time the hydraulic cylinder 13
Hydraulic oil is discharged from the chamber, and the elevating body 4 is lowered.
At this time, a predetermined air pressure is applied to the cylinder 14, and the rotating carrier 15 stops at a position where the air pressure applied to the cylinder 14 and the weight of the wire rod 16 placed on the rotating carrier 15 are balanced. be done. Thereafter, the pressure of the hydraulic oil supplied to one hydraulic cylinder 51b is reduced, the holding force between the fixed pawl 51a and the movable pawl 51c is loosened, and the clutch 48
The gear motor 36 is rotated in the direction of arrow B while being operated. Therefore, the drive shaft 35 is rotated in the direction of the arrow C, and the feed screw 43 is rotated in the direction of the arrow B via the gears 46, 45 and the clutch 48, and the actuating arm 50 holds the tip of the wire 16 with the chuck device 52. while moving in the direction of arrow E. At this time, since the holding force between the fixed claw 51a and the movable claw 51c is small, the chuck device 51 acts as a guide for the wire 16, and the operating arm 5
0 reaches a position close to the pulley 38, the gear motor 36 is deactivated and the wire 16 is placed under direct tension between the chuck devices 51, 52 of the actuating arms 49, 50. Thereafter, the slide plates 26 and 27 are moved apart and the support plates 32 and 32 are expanded around the pin 31, and at the same time the air cylinder 1 is extended and the movable frame 40 and the actuating arms 49 and 50 are expanded.
is rotated in the direction of arrow F, and the chuck devices 51, 52
The wire rod 16 held between the wire straightening rollers 2
8 and 29 and between the feed rollers 33 and 33, and in this state, the slide plates 26 and 2
7 is moved closer, the support plates 32, 32 contract around the pin 31, and the wire 16 is moved closer to the wire straightening/rollers 28, 29 and feed rollers 33, 33.
sandwiched between. After this, the chuck device 51,5
2 is released, the air cylinder 41 contracts, and the actuating arms 49, 50 are separated from the wire rod 16 and stand upward, and the feed rollers 33, 33
As the wire rod 16 rotates in the direction of arrow G, the tip end of the wire rod 16 is supplied into the wire rod supply pipe 22 by the wire rod supply device 30, and the setting operation of the wire rod 16 is completed. When the wire rod 16 is supplied to the header in this manner, the header starts operating and produces a heading product in a well-known manner. In this case, feed roller 3
When the wire rod 16 is sent toward the header by rotation in the direction of arrow G of 3 and 33, tension acts on the wire rod 16 between the wire straightener 25 and the rotary carrier 15, and
The detection contact body 5 is in the state shown in the figure a.
4 is now displaced outward, and the touch sensor 53 is activated. Then, the touch sensor 5
3, the gear motor 10 is driven and the rotary carrier 15 is driven in the direction of arrow A, and the wire 16 is fed out from the rotary carrier 15. Therefore, the wire straightener 25 and the rotating As shown by b in FIG. 6, no tension is applied to the wire 16 between the carriers 15, the detection contact body 54 returns to its normal position, the output from the touch sensor 53 disappears, and the gear motor 10 is stopped. , thereafter, the touch sensor 53 controls the gear motor 1.
0 is stopped and the wire 1 is removed from the rotating carrier 15.
6 is rolled out. Now, rotating carrier 1
When the wire rod 16 wound around 5 is consumed to the end,
The wire 16 is normally provided with a bent portion 16a necessary for drawing, and it is difficult to straighten this with the wire straightening machine 25. Therefore, when the end of the wire 16 reaches the wire straightening machine 25, another detection device (not shown) detects this and stops the operation of the header. Thereafter, the gear motor 36 is rotated in the direction of arrow B, the clutch 47 is actuated, and the feed screw 42 is rotated in the direction of arrow B, so that the actuating arm 49 is moved in the direction of arrow E to a position near the actuating arm 50. After being moved, the air cylinder 41 is extended and the actuating arm 50 is rotated in the direction of arrow F, and the chuck devices 51 and 52 feed the wire 1 between the feed rollers 33 and 33 and the wire supply pipe 22.
6 is checked. After this, air cylinder 41
Due to the contraction of the actuating arm 49, the gear motor 36 is driven in the direction of the arrow C, and the clutch 47 is actuated, so that the feed screw 42 is rotated in the direction of the arrow C, and the actuating arm 49 is moved in the direction of the arrow D. At the same time, the pressure of the hydraulic oil to one of the chuck devices 50 is reduced, so that the wire 16 remaining in the wire supply pipe 22 is discharged to the outside. The ends of the wire 16 discharged in this manner are received from the operating arms 49, 50 by a removal device (not shown) and moved to a predetermined disposal location. Thereafter, by repeating the above-described series of operations, a new wire rod 16 is automatically supplied to the header, and the header produces a forged product.

Note that the operating arms 49 and 50 of the wire supply mechanism 23
may move up and down instead of rotating, the wire straightening machine 25 may be provided as necessary, the feed rollers 33, 33 may be provided on the frame 21 side of the header, and the mounting table may also be provided. 8 can be rotatably provided directly on the pedestal 1, and the elevating body 4 can be omitted so that the rotary carrier 15 does not move up and down. Various modifications can be made without departing from the gist of the invention. .

As is clear from the above description, the present invention is capable of automatically setting the tip of a coiled wire to a supply destination such as a header, so that a new wire can be supplied when the coiled wire is used up to its terminal. It is possible to provide an automatic wire setting device such as a header suitable for automating wire rod setting.
