Description

Automatic rolling and bundling device for power cord cable {AUTOMATIC ROLLING AND BANDING APPARATUS FOR POWER CABLE}

The present invention relates to an automatic rolling and tying device for power cord cables. More specifically, in the packaging and delivery stages after production of power cord cables, the power cord cables are uniformly rolled and tied according to product specifications or customer requirements. , It is about an automatic rolling and binding device for power cord cables that can increase productivity by fully automating the process.

Power cord cables are used to supply power to various electronic devices. They are manufactured by covering the received wires with a single cable, stripping the core wires, pressing them, and molding the plugs using the insert injection method.

The power cord cable produced in this way is bundled into a rolling form after completing various electrical characteristic tests, packaged, and then shipped.

At this time, the rolling and binding work of the conventional power cord cable has been entirely dependent on manual work.

Briefly, as shown in Figure 5a, a worker wraps and rolls the finished power cord cable around two rods and then binds the middle of the cable bundle with a tie (iron string).

Because the rolling and binding of power cable cords is done entirely by hand, productivity is low, and the average production quantity varies depending on the worker's skill level, making it difficult to meet the shipment quantity.

Meanwhile, depending on the type of electronic device, the specifications (thickness of the cable, shape of the plug, etc.) of the power cord cable used are different, and the rolling specifications (length of rolling, number of times, etc.) required by each company receiving the product are also different.

Therefore, work must be carried out in accordance with each cable specification or rolling standard for each product, but in the case of manual work, rework is sometimes performed due to the different ability of each worker to judge the rolling standard, and there is a problem of very large tie consumption.

To solve this problem of manual work, a device for automatically tying ties has been developed and used, as shown in Figure 5b. However, this is a partially automated facility limited to tying ties, and the rolling work of the power cord cable still requires manual work by the operator. As the process progresses, the above-mentioned problems still exist, and there is a need to develop technology that can fully automate all rolling and binding operations of power cord cables. However, there are currently no fully automated facilities for this operation.

Accordingly, the present invention was devised to solve the problems described above.

After production, packaging and delivery of power cord cables, the power cord cables are rolled and tied uniformly according to product specifications or customer requirements, and the process is fully automated to increase productivity. Automatic rolling and bundling of power cord cables The purpose is to provide a device.

In order to achieve the above object, the automatic rolling and binding device for power cord cables according to the present invention,

A pair of pillars are installed on the left and right, and a rotary table that rotates to wind a cable around the pillars,

A transfer unit that grasps a bundle of coiled cables and transfers them back and forth,

A seating portion where the cable bundle transferred to the transfer unit is seated,

A tie supply machine that supplies a binding tie to the seating portion,

It is characterized by including a binding gripper that grips both ends of the tie and then rotates to bind the tie.

And in the power cord cable automatic rolling and binding device according to the present invention,

The rotary table is characterized by including a gap adjustment means for adjusting the gap between the pair of pillars.

In addition, the automatic rolling and binding device for power cord cables according to the present invention,

The rotary table includes a fixed gripper installed on one side of the pair of pillars to secure the plug of the cable,

It is provided on the other side of the rotary table and includes a fixing unit that holds the other side of the cable wound around the pillar.

In addition, in the automatic rolling and binding device for power cord cables according to the present invention,

The transfer unit includes a transfer gripper that can be raised and lowered,

The seating portion consists of a seating gripper that grips the cable bundle,

The tie supplier supplies ties from the upper part of the seating gripper in the forward and backward direction of the transfer gripper,

The descending cable bundle presses on the tie and the tie is wound around the cable bundle.

The automatic rolling and binding device for power cord cables according to the present invention,

The entire rolling and tying work of power cord cables, including rolling of cables using a rotary table, transporting and discharging using a transfer robot, and tying ties using a tie feeder and tying gripper, is fully automated, reducing differences in production quantity between workers while simultaneously reducing power By maintaining uniform quality according to the specifications and rolling standards of the cord cable, productivity can be dramatically improved compared to the conventional method relying on manual work.

The spacing between columns can be adjusted so that the rolling specifications can be changed in various ways. At the same time, after rolling, the cable bundle can be easily separated from the column and transported.

By holding the cable while the plug is fixed, it prevents the cable from bouncing at high speed when the rotary table rotates, preventing defective rolling work and injury to workers.

When supplying a bundle of cables using a gripper, the tie is automatically bent and placed on standby for tying, which has the effect of reducing work loss time for each process and ensuring that tying work is always performed evenly.

Hereinafter, the automatic rolling and binding device for power cord cables according to the present invention will be described with reference to the attached drawings.

The automatic rolling and binding device for power cord cables according to the present invention is a power cord cable that winds a predetermined length of a power cord cable (C) connected to a plug (P) to a predetermined length and wraps the entire cable bundle with a tie (T) to bind the power cord cable. It relates to an automatic rolling and binding device, and as shown in FIGS. 1 to 4B, it largely includes a rotary table 10, a transfer unit 20, a seating unit 30, a tie feeder 40, and a binding gripper 50. , a fixing unit 60, and these components are installed inside the main body (M) provided with doors that can be opened and closed, and the rotary table (10) is placed on the working part (W) where the front of the main body (M) is open. With this arrangement, the operator only manually inserts the power cord cable, and then the rolling and binding work is fully automated.

Specifically, the present invention,

A rotary table (10) on which a pair of pillars (11) and (12) spaced apart at a predetermined distance on the left and right are erected, and which rotates to wind a cable (C) using the pillars (11 and 12) as fulcrums,

A transfer unit (20) that grasps the coiled cable bundle, removes it from the pair of pillars (11) and (12), and then transfers it back and forth,

A seating portion 30 on which the cable bundle transferred to the transfer unit 20 is seated,

A tie supply machine (40) that supplies a binding tie (T) to the seating portion (30),

A binding gripper (50) that grasps both ends of the tie (T) and rotates to twist and bind the tie (T),

It is provided on the other side of the rotary table 10 and includes a fixing unit 60 that holds the other side of the cable C wound around the pillars 11 and 12.

The rotary table 10 is coupled to pillars 11 and 12 of a predetermined height on both sides of the upper surface, and rotates by receiving rotational power from the motor 13.

And the rotary table 10 includes a gap adjustment means for adjusting the gap between the pair of pillars 11 and 12.

As a spacing adjustment means of the present invention,

Each pillar (11) (12) is slidably coupled to the guide grooves (14) (15) arranged on the left and right sides of the rotary table (10), allowing the spacing to be adjusted.

In addition, one pillar 11 is connected to the piston of the cylinder 111 and is capable of moving forward and backward.

Accordingly, the cable (C) is hung on one of the pillars (11) (12) in accordance with the rolling standard, and both ends of the cable (C) are fixed to the fixed gripper (16) and the fixed unit (60), respectively, and the rotary table (10) ) rotates in one direction, the cable (C) is wound around the pillars (11) and (12) and the rolling operation is completed.

And when the transfer unit 20 grips and transfers the cable bundle after completion of rolling, the pillar 11 advances by the cylinder 111 and the gap between the pillars 11 and 12 narrows, the transfer unit ( 20) This cable bundle can be more easily gripped and pulled out.

In addition, the rotary table 10 includes a fixed gripper 16 that is installed on one side of the pair of pillars 11 and 12 and fixes the plug P of the cable C.

The fixed gripper 16 is operated by a cylinder 161, and prevents the plug P of the power cord from being wound around the cable bundle to a predetermined length.

In addition, in order to change the position of the fixed gripper 16 according to the length at which the plug P is not wound, the rotary table 10 has a guide groove 17 arranged diagonally with respect to one guide groove 15. Including, the fixed gripper 16 is slidably coupled to the guide groove 17 to enable position adjustment.

Subsequently, the transfer unit 20 has a guide 21 connected from the upper part of the rotary table 10 to the upper part of the seating part 30, and is capable of moving forward and backward by a motor 22 along the guide 21 to lift and lower. Includes transfer gripper.

The transfer gripper is composed of a first transfer gripper 23 that grips both ends of the cable bundle, and a second transfer gripper 24 that grips the plug P of the cable C.

The first transfer gripper 23 is provided on both ends of the bottom of the lifting plate 25 that is raised and lowered by the cylinder 251, and the second transfer gripper 24 is hinged at one end of the lifting plate 25. It is provided on the bottom of the rotating frame 26,

The first and second transfer grippers 23 and 24 are connected to each cylinder 231 and 241 to enable a gripping operation.

This transfer unit 20 is set by adjusting the position of each gripper 23 and 24 to suit the length of the rolled cable bundle and the position of the plug, and grips the cable bundle on which the rolling operation has been completed (including the plug (P). In the case of the core wire (not shown) on the other side of the plug (P), since it is light in weight, separate gripping is not required.) is transferred to the seating part 30, which is the location for the binding operation, and then the binding operation is performed while returning to the original position forward. Once this is completed, it moves backwards again to grasp the cable bundle and then moves forward to finally discharge the finished product with complete rolling and binding.

At this time, the number of times the discharge operation of the transfer unit 20 is completed is counted to facilitate production management.

The seating portion 30 fixes the cable bundle so that a tie (T) can be tied to the rolled cable bundle.

This seating portion 30 is composed of a seating gripper 31 that grips the cable bundle.

The seating gripper 31 is installed in an inverted manner opposite to the transfer grippers 23 and 24, and is capable of a gripping operation by the cylinder 32. A tie (T ) is provided with a support band (not shown) to elastically support it while guiding it horizontally.

Accordingly, the seating gripper 31 operates to grip the cable bundle when the cable bundle is lowered and seated by the transport grippers 23 and 24 in a state in which the tongs are spread, thereby preventing the tong bundle from being loosened during the binding operation.

The tie feeder 40 unwinds the tie (T) wound on a supply reel (not shown) and supplies it to the upper part of the seating unit 30, and although not shown in the drawing, it uses a cutter that cuts the tie (T) to a certain length. is provided.

Specifically, the tie feeder 40 operates to unwind the tie (T) of the supply reel while being guided to the guide rollers 41 and 42, so that the transfer gripper 23 and 24 are moved from the upper part of the seating gripper 31. Supply ties (T) in the forward and backward direction.

At this time, the supplied tie (T) is inserted into the above-mentioned support band and fixed horizontally.

In this state, the descending cable bundle presses on the tie (T), causing some of the tie (T) to be wrapped around the cable bundle.

In other words, in order to bind a bundle of cables with a tie (T), the straight tie (T) must be bent to wrap around the bundle of cables once. However, in the present invention, the tie (T) is pressed through the seating operation of the cable bundle, forming a 'U'. The process is performed automatically by bending it into a shape.

The binding gripper 50 is wrapped once around a bundle of cables and grips both ends of the tie (T) bent into a 'U' shape, then twists the tie (T) through rotation, so that the bundle of cables becomes the tie (T). to be bound together.

This binding gripper 50 is provided to be raised and lowered by a cylinder 51, and rotates by a motor 53 while a gripping operation is performed through the cylinder 52.

In addition, the binding gripper 50 includes push bars 54 arranged on both sides at a predetermined distance apart and formed with an upper and lower beam structure and an opening on the lower surface.

And the binding gripper 50 is connected to the rear end of the transfer plate 27 to which the transfer grippers 23 and 24 are connected, and the transfer grippers 23 and 24 and the binding gripper 50 are connected along the guide 21. ) operates forward and backward simultaneously.

Therefore, when the transfer grippers 23 and 24 move backward and then descend and the transfer grippers 23 and 24 move forward again while the cable bundle is seated on the seating gripper 31, the rear binding gripper 50 moves to the upper position of the seating gripper 31.

And when the binding gripper 50 descends, both ends of the tie (T) standing vertically are inserted between the tongs. In this state, when the binding gripper 50 rotates after the gripping operation, the tie (T) is twisted and the binding operation is performed. This is done.

At this time, the push bar 54 presses and holds both ends of the cable bundle, preventing the cable bundle from shaking during tie (T) binding.

Next, the fixing unit 60 has the other end of the cable C, which is not fixed unlike the plug P fixed to the fixing gripper 16 during rotation of the rotary table 10, to the pillars 11 and 12. It is safely supplied to the field and cooled.

Specifically, the fixing unit 60 includes a gripping roller 61 that guides the cable (C) being inserted and wound around the pillars 11 and 12, and the gripping roller 61 can be moved back and forth, left and right, and up and down. It includes cylinders 62 and 63 (the cylinder for forward and backward movement is built into the cover 64 and is not shown in the drawing).

This fixing unit 60 moves the cable (C) between the gripping rollers (61) and moves forward, left, and right while holding the cable (C), holding the cable (C) that is not wound around the pillars (11) (12). At the same time as preventing the other side from shaking, it rises from the bottom to the top so that the cable (C) can be wound consistently in the height direction of the pillars (11) (12).

That is, when the rotary table 10 rotates at high speed and the cable C is wound around the pillars 11 and 12, if the other side of the cable C is not fixed, the cable C oscillates due to the rotation speed. (Bounce) can cause damage to parts or injury to workers, so the above-described problem is solved by safely guiding the cable (C) to the pillars (11) and (12) and winding it through the fixing unit (60),

Furthermore, when the cable (C) is wound around the pillars (11) and (12), the supply height of the cable (C) is controlled upward according to the rotation speed of the rotary table (10), so that the cable (C) is connected to the pillar (11). It can be wound in a line up and down without overlapping the front, back, left and right sides of (12).

In the present invention of this configuration, only the work of fixing the plug (P) and the other side of the cable (C) by hanging the cable (C) on the pillars (11) (12) and inserting it is performed manually, and the other cable (C) Since the rolling, binding, transport and discharge operations are all fully automated, all problems arising from the conventional manual method can be solved and productivity can be dramatically improved.

Meanwhile, after binding the tie (T), the tied portion must be bent parallel to the cable bundle, so the present invention introduces an automatic bending means to the binding gripper 50 to fully automate even the relevant work.

As shown in FIG. 6, the automatic folding means includes an insertion groove 501 formed concavely and long along the left and right sides on the lower inner surface of each clamp portion 50A and 50B of the binding gripper 50, and an insertion groove A push block 55 is inserted into one of the 501s (50A), and is mounted on the outer surface of one of the tongs 50A and 50B, and the piston 561 penetrates the tongs 50A. Including a small cylinder 56 connected to the push block 55 to move the push block 55 forward and backward,

Each time the binding gripper 50 is gripped, the small cylinder 56 moves the push block 55 forward and backward to be inserted into one of the insertion grooves 501, so that the push block 55 is connected to a tie ( It is characterized by pushing the twisted part of T) to bend it.

Specifically, when the push block 55 is inserted backward into the insertion groove 501 of the one-side gripper 50A and the binding of the tie T is completed by rotation after the gripping operation of the binding gripper 50, When the tongs (50A) (50B) are opened, the small cylinder (56) operates to advance the push block (55) so that it is inserted into the insertion groove (501) of the other tongs (50B). When 55) moves forward, the twisted portion of the tie (T) located between the tongs (50A) (50B) is bent in the forward direction of the push block (55) and folded.

In the subsequent binding operation, after the binding of the binding gripper 50 is completed, when the tongs 50A and 50B are opened, the push block 55 of the other tongs 50B is moved backward by the small cylinder 56. As it is inserted into the insertion groove 501 of the one-side tongs 50A, the twisted portion of the tie T is bent in the backward direction of the push block 55 and folded.

Therefore, the twisted portion of the tie (T) can be automatically bent and folded as the forward and backward movement of the push block 55 is repeated during each binding operation.

In the above description of the present invention, the automatic rolling and binding device for the power cord cable (C) has been described with reference to the accompanying drawings. However, the present invention can be modified, changed, and replaced by various modifications, changes, and substitutions by those skilled in the art. Substitutions should be construed as falling within the protection scope of the present invention.
