Description

Device for transporting multiple wires for wire mesh manufacturing machine {WIRE FEEDING SYSTEM}

The present invention relates to a wire mesh manufacturing machine, and more particularly, by coupling a drive shaft that rotates forward by a drive motor to the upper side of a plurality of mounting tables, and coupling a clamp to the drive shaft together with a one-way clutch bearing so that the clamp rotates forward along with the drive shaft. Unlike the driving shaft, reverse rotation is also possible, and then the clamp is returned from the loading table by reverse rotation so that a plurality of wires supplied to the supply table can be attached, and the clamp is supplied to the supply table by the wire attachment means. By attaching two wires to the loading platform located on the opposite side of the feeding table, it can be transported to the loading platform. When transporting the wires of the feeding platform to the loading platform, the clamp rotates with the forward rotational force of the drive shaft rotated by the drive motor to carry and load the wire. After putting the wire on the table, the clamp can gradually return to the supply table direction by the return shaft that rotates in reverse with the relaxation force of the winding power of the mainspring, so the wires are transported in a more stable state without tangle of wires. While being rotated in reverse by the relaxation force of the mainspring, the clamp coupled with the coupling to the returning axis returns to the receiving groove again by the magnet of the magnet fixing frame while making gradual contact with the wire waiting in the supply table with a gentle pressing force. Since it can be attached, regardless of the height of the wires stacked on the supply table, it can be transported by sequentially attaching them to the receiving grooves while making contact with the wires located on the upper side first, so that improved transportability can be obtained and the magnet of the clamp When the clamp is rotated in reverse by the weight attached to the coupling tube opposite the fixed plate, the relaxation force of the spring is applied to increase the reverse rotational force of the clamp. As a result, the clamp gradually reverses while overcoming the weight of the magnetic fixed plate At the same time, it relates to a device for transporting a plurality of wires for a wire mesh maker that can prevent bending or breakage of wires by attaching them by magnetic force while contacting them with a subtle pressing force.

A wire transfer device for a conventional wire mesh maker has a previously filed and registered Patent Registration No. 10-2088614 "Wire Transfer Feeder for Wire Mesh Maker".

In the prior art, a plurality of holders having a plurality of support grooves formed while placing a step of a certain width on an inclined surface by being placed on a pedestal to sequentially supply the vertical wires supplied from the wire feeder to the welding device one by one, and the In order to sequentially move the vertical wires supplied from the wire feeder to the support grooves of the fixtures step by step, a plurality of movable tables having a plurality of transport grooves located on one side of the fixtures, and moving the movable tables A plurality of movable shafts coupled to the upper and lower sides of the movable bars for easy rotation in order to lift the vertical wires located in the transport groove to the support grooves of the fixing units and move them to the welding device, and to make the movable shafts circularly move A plurality of rotation pieces coupling the upper side to the other side of the movable shaft, a plurality of drive shafts coupling one side to the lower side of the rotation pieces to rotate the rotation pieces, and a plurality of drive shafts coupled to the other side of the drive shaft to rotate the drive shafts. A plurality of driving gears and interlocking gears, a plurality of idle gears rotatably coupled to the auxiliary shaft of the fixing unit engaged between the driving gear and the interlocking gear to rotate the driving gear and interlocking gears in the same direction, and the driving shafts An output shaft installed on a support that connects a plurality of drive pulleys connected to interlocking pulleys and drive belts coupled to the other end of the drive shafts to rotate, and an output pulley coupled to the output shaft and an output belt. It has a configuration having an output motor fixed to the bottom surface coupled to a rotating pulley.

That is, in the above prior art, the vertical wire in the state of receiving support from the wire feeder and supported by the supporting groove formed at the lower end of the fixing rod is coupled to the rotating piece of the driving shaft and coupled to the movable shaft performing circular motion. By the chain action of lifting and raising to the support groove of the next step, it is possible to supply the vertical wires to the welding device regularly while maintaining the set interval, thereby reducing the defect rate and improving productivity due to the rapid and accurate transfer and supply of vertical wires. It is an invention that can.

The conventional wire transfer supply device is a device that receives wire from a wire feeder and supplies it to a welding device one by one at precise timing.

In addition, in the wire feeder, a large amount is supplied at once by lifting both sides of the wires in a state where two workers are located on both sides of the wire feeder.

Therefore, in the wire feeder, despite the fact that the wires must be accurately supplied one by one to the stair-shaped fixture of the wire transfer supply device, the wires are often tangled and supplied by 2-3. As a result, the welding defect rate of the welding device is increased. had a crucial problem.

This is a phenomenon that occurs due to the absence of a device for separating the wires one by one and supplying them to the stair-shaped fixture at precise timing, which causes a large amount of defective welding products to be discarded.

Accordingly, a number of "devices for conveying individual wires for wire mesh manufacturers" (identified by the same applicant) that accurately supply wires one by one to a stair-shaped fixture, away from the method in which workers manually supply wires to the conventional wire feeder. An auxiliary device was devised that allows the "device for transporting individual wires for a wire mesh maker" to supply wires to a stair-type fixture at precise timing by supplying two wires without entanglement.

When the wires of the supply table are transported to the loading table, they are transported by the clamp rotated by the forward rotational force of the driving shaft rotated by the driving motor, and after putting the wires on the loading table, the clamp rotates in reverse with the relaxation force of the winding force of the mainspring. Since it is possible to make a gradual return in the direction of the supply table by the return shaft that is used, the wires can be transported in a more stable state without entanglement of the wires. The wire located on the upper side regardless of the height of the wire stacked on the supply table because the combined clamp can be re-attached to the receiving groove by the magnet of the magnet fixing frame while making gradual contact with the wire waiting on the supply table with a gentle pressing force. Improved transport workability can be obtained by sequentially attaching to the receiving grooves while making contact with them first, and relaxation of the mainspring when the clamp rotates reversely by the weight attached to the coupling tube opposite the magnet fixing plate of the clamp As a result of increasing the reverse rotational force of the clamp by applying force to the clamp, the clamp overcomes the weight of the magnet fixing plate and gradually rotates in reverse, and at the same time, it can be attached by magnetic force while contacting the wires with a gentle pressing force. It serves the purpose of preventing bending or breakage.

The operation of the present invention thus formed is described as follows.

Figure 1 is an overall view shown to explain the configuration of a device for transferring a plurality of wires of the present invention, Figure 2 is a view shown to explain the configuration of connecting the drive shaft and the return shaft of the device for transferring a plurality of wires of the present invention 3 is a diagram for explaining the coupling relationship between the return shaft and the spring in the apparatus for transporting a plurality of wires according to the present invention. When a plurality of wires 200 are supplied to the supply stand 161 as shown in FIG. The driving motor 101 mounted on the upper side of the one-side loading table 162 is driven by an instruction from a control box (not shown).

By driving the drive motor 101, the drive shaft 102 connected to the drive motor 101 also rotates forward at a set number of revolutions.

In addition, the coupling pipe 112 of the clamp 111 coupled together with the one-way clutch bearing 121 on the drive shaft 102 also rotates forward, and the coupling 132 on the other side of the coupling pipe 112 The connected return shaft 131 also rotates forward.

In addition, the inner end 142 is coupled to the coupling groove 132 of the other end of the return shaft 131 by forward rotation of the return shaft 131, and the outer end is connected to the insertion groove 152 of the case 151. The mainspring 141 coupled to 143 accumulates elasticity while being wound in the direction of the arrow as shown in FIG. 7 .

On the other hand, the clamp 111 coupled to the drive shaft 102 contacts the wires 200 supplied to the supply stand 161 and the plurality of receiving grooves 114 formed in the magnet fixing plate 113, and at the same time, the magnet fixing plate The driving shaft 102 and the coupling pipe ( 112) rotates forward to the position indicated by the solid line in FIG.

Therefore, the plurality of wires 200 attached to the receiving groove 114 of the clamp 111 come into contact with the inclined surface 163 of the mounting table 162 and the magnetic force of the magnet 115 fixed to the clamp 111 At the same time, it is released from the loading table 162, and the clamp 111 rotates forward more than the inclined surface 163, and then stops at the position set by the detection of the sensor (shown).

As described above, when the clamp 111 is stopped, the power supplied to the driving motor 101 is cut off according to the instruction of the control box.

As described above, when the drive motor 101 stops, the forward rotational force of the drive shaft 102 is lost, so from now on, the drive shaft 102 rotates forward while the mainspring 141 in the case 151 is unwound, resulting in relaxation. The force causes the return shaft 131 to reverse rotation.

That is, since the inner end 142 of the mainspring 141 is coupled to the coupling groove 132 formed on the other side of the return shaft 131, the return shaft 131 can rotate backward.

As described above, due to the reverse rotation of the return shaft 131, the coupling pipe 112 of the clamp 111 connected by the return shaft 131 and the coupling 132 is also reversely rotated.

At this time, since the coupling pipe 112 is connected to the drive shaft 102 by the one-way clutch bearing 121, forward rotation of the drive shaft 102 together with the one-way clutch bearing 121 occurs during forward rotation, but during reverse rotation, the drive shaft 102 rotates in one direction. Since only the coupling pipe 112 together with the outer race of the clutch bearing 121 can reversely rotate, the driving shaft 102 cannot rotate reversely and remains stationary.

Therefore, the magnet fixing plate 113 connected by the connecting piece 116 to the coupling pipe 112 of the clamp 111 reversely rotates from the solid line position to the imaginary line position in FIG. It is possible to attach the wires 200 to the receiving grooves 114 by the magnetic force of the magnet 115 while making contact with the wires 200 waiting on the supply table 161 with a gentle pressing force. .

And, in a state where the wires 200 are heaped up on the supply table 161 by the clamp 111 rotated by the mainspring 141, the wires 200 located on the upper side are attached and transported, and then The wires 200 loaded therein are transported, and eventually, the last wires 200 located on the bottom surface of the supply stand 161 can be sequentially and neatly transported.

As described above, when the plurality of wires 200 are attached to the accommodating grooves 114 of the clamp 111, the drive motor 101 is driven again by the instruction of the control box, and the drive shaft 102 and the clamp 111 are fixed. By rotating, a plurality of wires 200 can be loaded on the loading table 162 in the same manner as described above.

On the other hand, when the clamp 111 is rotated in the reverse direction by the weight body 117 attached to the coupling pipe 112 opposite the magnet fixing plate 113 of the clamp 111, the force is applied to the relaxation force of the spring 141. As a result of increasing the reverse rotational force of the clamp 111, the clamp 111 gradually rotates in reverse while overcoming the weight of the magnet fixing plate 113, and at the same time contacts the wires 200 with a gentle pressing force by magnetic force. it can be attached
