[0002] Cable ties are used in a variety of applications in manufacturing and production, and are widely used due to their low cost, simple operation, wide adaptability, and reliable bundling. To save costs and improve efficiency, automated or semi-automated cable ties are often used in production lines to bundle products. However, because the difficulty of bundling with a cable tie machine is proportional to the length and distance of the tie, most cable tie machines on the market are designed for short bundles with short distances, while few are suitable for long bundles with long distances. To expand the adaptability and performance of cable tie machines and address the technical challenges of bundling long ties over long distances, it is necessary to design an automatic cable tie device that can automatically load and bundle cables while ensuring bundling efficiency and quality.

In the initial state, the tail clamp is located directly below the tail guide block, the clamping groove of the tail clamp is aligned with the through groove of the tail guide block, the clamping groove on the head clamp is aligned with the through groove on the head guide block, the oblique groove of the head guide block is aligned with the rectangular groove of the head clamp, the clamping groove of the tail clamp is parallel to the clamping groove of the head clamp, and the pop-up rod is horizontally located in the discharge trough.

[0009] Preferably, the lifting mechanism includes a lifting plate, a driving gear, a rack group and a sliding rod group. The rack group consists of two racks vertically fixed on the frame and arranged at intervals. The lifting plate is hinged with four driving gears arranged in an array. Each rack is engaged with two driving gears, and each driving gear is driven to rotate by a motor; the sliding rod group consists of two sliding rods. The lifting plate is fixed to each sliding rod through a connecting frame.

[0015] The present invention provides a method for bundling linear cables using an automatic cable tie machine, which is specifically as follows:

[0016] Connect the pneumatic push rod to the air pump via an air pipe. Place the handles of multiple straps with handles for bundling items between the head and tail clamps, and the clamping mechanism will clamp the cable tie. The lifting mechanism then drives the clamping jaw frame to lower the cable tie by a preset distance of one through the fixed clamping jaw group, the limit clamping jaw, and each Y-shaped bracket, so that the ends of the cable tie body enter the two through slots and the head of the cable tie enters the oblique slot opening. Guided by the oblique slot opening and each through slot, the ends of the cable tie body pass through the two through slots and embed into the two clamping slots. The head of the cable tie passes through the oblique slot opening and enters the rectangular slot. Driving member one drives the active and driven clamping jaws to open, releasing the clamp on the cable tie body. Simultaneously, driving member two drives the limit clamping jaw to rotate away from the corresponding Y-shaped bracket, releasing the restriction on the cable tie body. The lifting mechanism then drives the clamping jaw frame to lower by a preset distance of two. Then the head servo drives the head clamp to drive the head of the cable tie to rotate 90 degrees forward, and the tail servo drives the tail clamp to drive the end of the cable tie away from the head to rotate 180 degrees forward, so that the tail of the cable tie is aligned with the slot of the head of the cable tie; the air pump controls the pneumatic push rod to drive the tail servo frame to drive the tail clamp and the tail of the cable tie to move horizontally in the direction close to the head clamp, so that the tail of the cable tie passes through the inner side of the handle of each object to be tied, and is inserted into the slot of the head of the cable tie from the open side of the rectangular slot. The middle part of the cable tie body is located outside the handle of each object to be tied, completing the tying. Each item to be bundled is bundled; the pop-up servo drives the pop-up rod to rotate upward, and the pop-up rod pushes the completed bundle out of the rectangular slot and each clamping slot; finally, the air pump controls the pneumatic push rod to drive the tail servo frame to drive the tail clamp body to move horizontally away from the head clamp body to its original position, the pop-up servo drives the pop-up rod to rotate downward to its original position, the head servo drives the head clamp body to reverse 90° to its original shape, the tail servo drives the tail clamp body to reverse 180° to its original shape, and at the same time, the lifting mechanism drives the lifting plate to rise to its original position, and the rotating servo drives the clamping claw frame to rotate to its original shape.

[0017] Preferably, the process of the clamping mechanism clamping the cable tie is as follows: the driving member 1 drives the active jaw and the driven jaw to close, so that the active jaw and the driven jaw clamp the end of the cable tie body close to the head, and at the same time, the driving member 2 drives the limiting jaw to rotate in the direction close to the corresponding Y-shaped bracket, so that the end of the cable tie body away from the head is restricted between the limiting jaw and the corresponding Y-shaped bracket; wherein, the two Y-shaped brackets fit the cable tie in the vertical state; the rotary servo drives the jaw frame to rotate the cable tie through the fixed jaw group, the limiting jaw and each Y-shaped bracket, so that the cable tie is adjusted to a horizontal state.

[0018] The present invention has the following beneficial effects:

[0019] The present invention can realize the bundling of items with handles with cable ties, has good bundling efficiency and quality, and is suitable for bundling longer cable ties. Specifically, in the present invention, the fixed clamping claw group of the clamping mechanism clamps the end of the cable tie body close to the head, and the limiting clamping claw and the corresponding Y-shaped bracket limit the end of the cable tie body away from the head, and then cooperates with the lifting mechanism to send the cable tie through the V-grooves and through grooves of the head guide block and the tail guide block in the guide mechanism to the cable tie mechanism, thereby realizing the loading of the cable tie, and the outlet composed of the two through grooves and the oblique groove is aligned with the inlet composed of the two clamping grooves and the rectangular groove in the head clamp and the tail clamp of the cable tie mechanism, and the shape of the outlet and the inlet are adapted to the shape of the cable tie, and the distance between the outlet and the inlet is less than the width of the cable tie, thereby ensuring that the cable tie can be accurately The clamping method of one end in which the fixed jaw group clamps and the limiting jaw does not clamp improves the bending adaptability of the cable tie in the horizontal plane when loading the material. When the through slots of the head guide block and the tail guide block are not designed to be aligned, the material can be loaded successfully, thereby ensuring the bundling efficiency and quality. In addition, the cross-section of the material clamping grooves in the head clamp body and the tail clamp body is V-shaped, which is adaptable when the material clamping grooves of the head clamp body and the tail clamp body are not designed to be aligned. After the two ends of the cable tie body are embedded in the two material clamping grooves, the material clamping grooves generate a clamping force on the cable tie body, thereby preventing the tail of the cable tie from moving when it is inserted into the slot of the cable tie head located in the rectangular groove, thereby further ensuring the bundling efficiency and quality. In the cable tie mechanism, the head servo drives the head clamp 90° forward and reverse, and cooperates with the tail servo to drive the tail clamp 180° forward and reverse, achieving a clever switch between receiving the cable tie and aligning the tail of the cable tie with the slot of the head. The pneumatic push rod drives the tail servo frame to drive the tail clamp and the tail of the cable tie through the inside of the handle of each item to be tied and insert it into the slot of the cable tie head. The pop-up servo drives the pop-up rod to push the completed cable tie out of the rectangular slot and each clamping slot, completing the cable tie binding of each item to be tied. The pneumatic push rod can be used to change the initial distance between the tail clamp and the head clamp to achieve cable tie binding of different lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] As a preferred embodiment, the housing of the rotary servo 10 is fixed to the lifting plate via a rotary servo frame 12 , and the output shaft of the rotary servo 10 is fixed to the clamping frame 11 .

The driving gear and the driven gear are meshed and are both hinged to the corresponding Y-shaped bracket, and the driving gear is driven to rotate by the driving servo 9; the driving jaw 15 and the driven jaw 16 are fixed to the driving gear and the driven gear respectively.

[0042] More preferably, the structure of the second driving member is consistent with that of the first driving member, and the limiting clamping claw 8 is fixed on the driven gear of the second driving member.

[0043] As a preferred embodiment, the head guide block 17 and the tail guide block 18 are fixed to the frame 5 via two guide frames 19 .

[0044] As a preferred embodiment, the housing of the head servo 22 is fixed to the frame 5 via the head servo frame 24 , and the output shaft of the head servo 22 is fixed to the head clamp 20 .

[0045] As a preferred embodiment, the cylinder of the pneumatic push rod is fixed to the frame 5 through a fixing frame, and the piston rod of the pneumatic push rod is fixed to the tail servo frame 25.

[0046] As a preferred embodiment, the housing of the pop-up servo 27 is fixed to the head clamp 20 via a pop-up servo frame 28 , and the output shaft of the pop-up servo 27 is fixed to the pop-up rod 29 .

[0047] Among them, the pneumatic push rod 26 is connected to the air pump through an air pipe. The air pump, motor, rotary servo 10, head servo 22, tail servo 23, pop-up servo 27 and each driving servo 9 are all controlled by a controller, and the signal output end of each photoelectric sensor 13 is connected to the controller.

[0048] A method for bundling linear cables using an automatic cable tie machine is as follows:

[0049] The pneumatic push rod 26 is connected to the air pump through an air pipe, and the handles of multiple items to be tied with handles (such as laundry detergent bottles, cups, kettles, suitcases, folding chairs and folding tables, baskets, handbags or bags) are placed between the head clamp 20 and the tail clamp 21 (each item to be tied is transported by a conveying device or placed manually); the driving member 1 drives the active clamp 15 and the driven clamp 16 to close, so that the active clamp 15 and the driven clamp 16 clamp the end of the cable tie body close to the head, and at the same time, the driving member 2 drives the limiting clamp 8 to rotate in the direction close to the corresponding Y-shaped bracket, so that the end of the cable tie body away from the head is restricted between the limiting clamp 8 and the corresponding Y-shaped bracket; wherein, the two Y-shaped brackets fit the cable tie 4 in the vertical state, and the cable tie can be sent to the clamping mechanism 1 by the cable tie screening mechanism or manually; the controller controls the rotary servo 10 to drive the clamp frame 11 to drive the cable tie to rotate through the fixed clamp group 7, the limiting clamp 8 and each Y-shaped bracket, so that the cable tie is adjusted to a horizontal state.

[0050] Then the controller controls each motor to drive each driving gear to rotate forward synchronously, and each driving gear meshes with the tooth surface of the corresponding rack 14, thereby driving the lifting plate to descend. The lifting plate drives the cable tie to descend a preset distance through the clamping jaw frame 11, the fixed clamping jaw group 7, the limit clamping jaw 8 and each Y-shaped bracket, so that the two ends of the cable tie body enter the two through grooves, and the cable tie head enters the oblique groove opening. Through the guiding effect of the oblique groove opening and each through groove, the two ends of the cable tie body pass through the two through grooves and are embedded in the two clamping grooves 30, and the cable tie head passes through the oblique groove opening and enters the rectangular groove, as shown in FIG. Figure 12As shown, since the limiting clamping claw 8 only applies downward pressure to the end of the cable tie body away from the head, it prevents the cable tie from being displaced in the vertical direction when passing through the guide mechanism 2, but the end of the cable tie body away from the head can be offset in the horizontal direction, so that when the through grooves of the head guide block and the tail guide block are not aligned, the material can be successfully loaded, thereby ensuring the bundling efficiency and quality. In addition, the cross-section of the material clamping groove in the head clamp body and the tail clamp body is V-shaped. When the material clamping grooves of the head clamp body and the tail clamp body are not aligned, the cable tie body is away from the head. One end of the head and the head of the cable tie can also enter the corresponding clamping groove 30 and rectangular groove respectively; the driving member 1 drives the active clamping jaw 15 and the driven clamping jaw 16 to open, loosening the clamping of the cable tie body, and at the same time, the driving member 2 drives the limit clamping jaw 8 to rotate in the direction away from the corresponding Y-shaped bracket, loosening the restriction on the cable tie body, and the controller controls each motor to drive the driving gear to rotate synchronously forward, so that the clamping jaw frame 11 drops a preset distance of two (which can be positioned by the photoelectric sensor 13 at the lower end of the rack 14), avoiding interference with subsequent cable tie work. Among them, the distance between the head clamping body 20 and the head guide block 17, and the distance between the tail clamping body 21 and the tail guide block 18 are both smaller than the width of the cable tie, preventing the two ends of the cable tie body and the head from being unable to enter the head clamping body 20 and the tail clamping body 21 after being guided by the two through slots and the oblique slot.

[0051] Then the controller controls the head servo 22 to drive the head clamp 20 to drive the head of the cable tie to rotate 90 degrees forward, and controls the tail servo 23 to drive the tail clamp 21 to drive the end of the cable tie away from the head to rotate 180 degrees forward, so that the tail of the cable tie is aligned with the clamping slot of the head of the cable tie (when the clamping slots of the head clamp and the tail clamp are designed not to be aligned, the center of the rectangular slot of the head clamp 20 is designed to be aligned with the central axis of the clamping slot of the tail clamp after the head clamp 20 rotates 90 degrees forward). Figure 13 As shown; the controller controls the pneumatic push rod 26 through the air pump to drive the tail servo frame 25 to drive the tail clamp 21 and the tail of the tie to move horizontally in the direction close to the head clamp 20, so that the tail of the tie passes through the inner side of the handle of each item to be tied, and is inserted into the slot of the head of the tie from the open side of the rectangular groove. The middle part of the tie body is located outside the handle of each item to be tied, so as to achieve the bundling of each item to be tied; the controller controls the pop-up servo 27 to drive the pop-up rod 29 to rotate upward, and the pop-up rod 29 pushes the tied tie out of the rectangular groove and each clamping groove 30; wherein, since the cross-section of each clamping groove 30 is V-shaped, after the two ends of the tie body are embedded in the two clamping grooves 30, the clamping grooves 30 generate a clamping force on the tie body, thereby preventing the tie body from moving when the tail of the tie is inserted into the slot of the head of the tie.

[0052] Finally, the controller controls the pneumatic push rod 26 through the air pump to drive the tail servo frame 25 to drive the tail clamp 21 to move horizontally away from the head clamp 20 to its original position. The controller controls the pop-up servo 27 to drive the pop-up rod 29 to rotate downward to its original position, controls the head servo 22 to drive the head clamp 20 to reverse 90° to its original state, and controls the tail servo 23 to drive the tail clamp 21 to reverse 180° to its original state. At the same time, the controller controls each motor to drive each drive gear to reverse synchronously, drive the lifting plate to rise to its original position (which can be positioned by the photoelectric sensor 13 at the upper end of the rack 14), and control the rotary servo 10 to drive the clamp frame 11 to rotate to its original state; the bundled items are taken away (delivered by a conveying device or taken away manually), thereby completing the bundling work of each item to be bundled.

[0053] In the initial state, the pneumatic push rod 26 drives the tail servo frame 25 to drive the tail clamp 21 to move, thereby changing the distance between the tail clamp 21 and the head clamp 20, thereby enabling the bundling work using cable ties of different lengths.
