Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a device for taking out a coiled wire loaded on a carrier.

0002

[Conventional technology]

For example, in the manufacturing process of welding wire, the wire is first placed in a carrier to form a coil. The carrier is then moved to the next process, where it is loaded with a wire removal device. Depending on the position, the wire can be pulled up in the axial direction of the carrier and taken out for processing such as wire drawing. It will be done.

0003 This wire extraction device uses a liftable arm that protrudes horizontally from the support. A wire guide hole is provided at the tip, and a coiled wire is loaded directly below this guide hole. Position the carrier and move the wires sequentially in the axial direction of the carrier from the top end of the stack of coiled wires. A device is known that pulls up the material and takes it out through a guide hole.

0004

[Problem that the idea aims to solve]

In such a vertical wire rod take-out device, the wire guide hole has conventionally been fixed. sand That is, as shown in Fig. 3, the guide die 1 having the guide hole 5 of the wire rod 4 is It was stored in a storage case 2 attached to the holder and secured by tightening bolts 3. However, if the guide die 1 that guides the wire rod 4 is fixedly provided, the wire rod 4 cannot be pulled up. As shown in FIG. 4, the guide hole 5 wears unevenly over time due to the violent movement of the wire rod 4. It deforms and forms a narrow groove 5a. In this way, the guide die 1 guide If a narrow groove 5a is formed in the hole 5, it is difficult for the wire to be pulled up at high speed to fit into the groove 5a. As a result, wire breakage, tangles, etc. will occur frequently. Therefore, conventional extraction devices We are forced to frequently replace die 1, which leads to a decline in equipment operating rate. Ta.

[0005] This invention is related to the improvement of the conventional wire extraction device mentioned above, and is based on the guide By preventing deformation due to uneven wear of the guide hole of the die, we aim to extend the life of the wire rod. We propose a wire extraction device that eliminates wire breakage, tangles, etc., and allows smooth extraction at all times. The purpose is to provide

[0006]

[Means to solve the problem]

The wire extraction device of the present invention achieves this purpose. Pull up the wire from the top end of the wire stack in the axial direction of the carrier and attach it to the lifting arm. A device for taking out a wire rod through a guide hole of a guide hole member, wherein the wire is taken out through a guide hole of a guide hole member. The hole member includes a guide die having a wire guide hole and the guide die in a horizontal plane. It is characterized by consisting of a storage case that can be freely rotated and stored with ample space.

[0007]

[Effect]

In this design, the guide die with the guide hole for the wire rod can be rotated freely. It is stored in a storage case. Therefore, the guide die rotates as the wire moves. As the wire moves, the wire rod and guide hole rub against each other, causing uneven wear of the guide hole. is suppressed.

[0008]

【Example】

The present invention will be explained below based on embodiments shown in the drawings. Figure 1 shows the entire take-out device. In Figure 1, 6 is a column, and 7 is a column A lifting arm is provided on one side, and the tip of the lifting arm 7 is for passing the wire 4 that has risen. A guide hole member 8 having a second guide hole is attached.

[0009] The lifting arm 7 connects the supporting member 9 of the lifting arm 7 fitted to the column 6 with an air cylinder. It can be raised and lowered by being suspended by a chain 11 via a chain 10. 1 2 is a roller attached to the tip of the telescopic piston rod 13 of the air cylinder 10. , 14 are rollers attached to the upper end of the support column 6, and these rollers 12 and 14 are connected to the chain. This is a roller for changing the direction of the engine 11.

0010 15a, 15b, 15c, 15d are guide rollers, 16 is from the guide hole member 8 A guide fence 17 is provided on the arm 7 and opens downward like a trumpet, and reference numeral 17 indicates a guide hole member 8. The carrier is placed below the guide hole of the carrier and is loaded with a laminate 18 of coiled wire. Ru. At the top of the carrier shaft 19 of the carrier 17, there is an ascending wire rod 4 having an inverted conical shape. A guide ring member 20 is attached to prevent squeezing.

[0011] 21 is a forklift, and the two forks 21A of the forklift 21 are Scoop up the coiled wire stack 18 loaded on the rear 17 and take out the wire 4 As the height of the laminate 18 decreases, the guide hole member 8 and the laminate 1 rise. 8. Keep the distance H to the top end constant. 22 is an optical level sensor with an upper limit level sensor. It consists of a sensor 22a and a lower limit level sensor 22b, and the upper end position of the stacked body 18 is at the level. It should be within the detection range of the sensor 22, that is, between the detection levels of the sensors 22a and 22b. This is detected when the forklift 21 lifts up via the controller. A signal and a stop signal are sent, and the upper end of the laminate 18 is always within the detection range of the level sensor 22. Drive the fork 21A as shown in . The guide hole member 8 and the upper end of the laminate 18 The reason for keeping the distance H constant is that during this period the wire rod 4 rises while turning, but the distance H If it is too large, the turning radius of the wire rod will become excessive or the wire rod will rise erratically. On the other hand, if it is too small, it will wrap around the carrier shaft and become tangled. Therefore, the distance H must be set to an appropriate predetermined distance that allows the wire to be pulled up easily and smoothly. Keep it separate.

0012 When the coiled wire on the fork 21A is pulled up and disappears, the fork 21 Lower A to the lower limit position and move backwards as shown by the arrow to take out the empty carrier and place the next coil. A carrier loaded with loop-shaped wire rods is carried in, and the same operation as last time is repeated. child In this case, the starting and ending ends of the coiled wire rods of both the old and new carriers are connected by welding. The removal of material 4 is continuous.

[0013] FIG. 2 shows an example of the guide hole member 8 attached to the lifting arm. The guide hole member 8 is A guide die having a guide hole 5 having a diameter that allows the wire rod 4 to pass through it with ease. 1 and this guide die 1 are housed with enough space and placed in the position corresponding to the guide hole 5. and a storage case 23 having a through hole. Storage case 23 contains guide die 1 outer diameter, inner diameter that exceeds the height (e.g. 4 mm larger than the guide die outer diameter), height (for example, 4 mm higher than the guide die height). It consists of a cover plate 23b fixed to the main body 23a with bolts 24. A storage case like this Place the guide die 1 in the space 23 with some clearance, that is, in a horizontal plane, as shown in Figure 2. Since the wire rod 4 is rotatably stored in the guide die when it passes through the guide hole 5, The wire rod 1 comes to rotate with the movement of the wire rod 5, which rises while turning. subordinate Therefore, the friction between the wire rod 4 and the guide hole surface becomes smaller, so there is no gas caused by rubbing of the wire rod. Uneven wear of the id hole can be suppressed.

[0014]

[Effect of the idea]

According to the wire rod extraction device of this invention explained above, the guide hole of the guide die is Since the occurrence of uneven wear is suppressed, lines caused by deformation of the guide hole due to uneven wear are The occurrence of tangles, tangles, wire breaks, etc. of materials is extremely reduced. Therefore, the burden on the worker is reduced. At the same time, it is possible to prevent a decline in equipment operating rate.
