Description

Technical Field

[0001] The invention belongs to the field of automation technology, in particular to an automatic rope and belt arranging machine. Background Art

[0002] In the clothing, footwear and hat accessories industry, such as belts, shoelaces or hat straps, the two ends of the ropes are generally coated with rubber to prevent loose threads. The company's previous patent application disclosed an automatic rope head soaking machine (publication number CN215714235U), which can prepare various required coatings on the rope heads. The machine places the jig or fixture with the rope installed (that is, the rope fixing device in the patent specification) into the glue liquid for dipping (or soaking head). When the glue liquid completely covers the rope end, it is taken out, and then the glue liquid solidifies to form a product, which is sent to the clothing or footwear factory for assembly. At present, arranging the ropes on the fixture (or fixture) is generally a pure manual operation. The cut ropes are clamped to the fixture one by one by the hands of the employees to form a neat arrangement, and then dipped in glue. This clamping operation is inefficient, and the current manual operation cost is high. Therefore, it is necessary to develop a device that can completely replace the manual clamping and arranging operation. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1 to Figure 14 As shown, the present invention provides a technical solution: comprising a rope straightening mechanism 1, a length measuring mechanism 2, a fixed-point clamping mechanism 3, a cutting mechanism 4, a rope pulling mechanism 5, a fixed-length mechanism 6, a clamping mechanism 7 and a clamp conveying mechanism 8,

[0042] The rope straightening mechanism 1 is used to straighten the rope during its flow to prevent it from getting tangled.

[0043] The length measuring mechanism 2 is arranged on one side of the rope straightening mechanism 1, and is used to measure the length of the rope when it flows through.

[0044] The cutting mechanism 4 is used to cut the continuous rope into small segments of equal length according to a preset length;

[0045] The rope pulling mechanism 5 is used to clamp the farthest end of the rope and pull it to a preset length before clamping the other end of the rope to facilitate cutting of equal length;

[0046] The fixed-point clamping mechanism 3 is used to intermittently clamp the rope belt to facilitate cutting by the cutting mechanism;

[0047] The length-fixing mechanism 6 is used to stretch the rope belt longitudinally when the preset length is greater than the pulling length, so that the rope belt can reach the preset length when it is pulled to the farthest end;

[0048] The clamping mechanism 7 is used to place the small sections of rope neatly on the clamp for arrangement, and the clamp conveying mechanism is used to transfer the unloaded clamp and transport it to the clamping station for clamping, and after clamping is completed, the fully loaded clamp is conveyed outward.

[0049] According to the flow order of the rope, it passes through the rope straightening mechanism 1, the length measuring mechanism 2, the fixed-point clamping mechanism 3, the cutting mechanism 4, the rope pulling mechanism 5, the fixed-length mechanism 6, the clamping mechanism 7 and the clamp conveying mechanism 8 in turn.

[0050] The rope straightening mechanism 1 comprises a first frame 10, on which a first straightening component 11, a second straightening component 12 and a rope shortage detection component 13 are installed; the first straightening component 11 is synchronously driven and connected with the second straightening component 12.

[0051] The first straightening component 11 includes a straightening motor 11A installed on the first frame, the output shaft of the straightening motor 11A is drivingly connected to a straightening drum 11B, the output shaft of the straightening motor 11A is transmission-connected to a first synchronous wheel 12C, the first synchronous wheel 12C is connected to a second synchronous wheel 12D via a belt, the second synchronous wheel 12D is transmission-connected to a swing arm 12B via a connecting rod 12A, one end of the swing arm 12B is hinged to the first frame 10, and the second straightening component 12 includes a connecting rod 12A and a swing arm 12B transmission-connected thereto.

[0052] The rope roll is placed under the swing arm 12B. When one end of the rope passes through the swing arm and the straightening drum in turn, the straightening motor drives the straightening drum to rotate 360 ​​degrees counterclockwise, which is opposite to the flow direction of the rope. Since the straightening drum has a rectangular cross-section, when the straightening drum rotates, the rope will jump up and down on the surface of the straightening drum, making the flow of the rope smoother. At the same time, the swing arm will also swing back and forth within a certain angle, simulating the action of the arm constantly pulling the rope, making the flow of the rope smoother and preventing knotting or entanglement.

[0053] The length measuring mechanism 2 includes an encoder bracket 21 fixedly mounted on the first frame 10, the encoder bracket 21 is fixedly connected to a lower guide wheel bracket 23 through a connecting pin 22, a rotatable encoder lower guide wheel 24 is mounted on the lower guide wheel bracket 23, an upper guide wheel bracket 25 is hinged at one end of the connecting pin 22, an encoder upper guide wheel 26 abutting against the encoder lower guide wheel 24 is mounted on the upper guide wheel bracket 25, an encoder 27 is coaxially connected to the encoder upper guide wheel 26, a proximity switch sensor 28 for detecting rope knotting is mounted on the encoder bracket, and two supporting guide wheels 29 are mounted on each side of the length measuring mechanism 2.

[0054] The rope will pass between the lower guide wheel 24 of the encoder and the upper guide wheel 26 of the encoder. When passing through, it will drive the lower guide wheel 24 of the encoder and the upper guide wheel 26 of the encoder to rotate. Since the upper guide wheel 24 of the encoder is connected to the encoder 27, the length of the rope passing through will be automatically measured. At the same time, a proximity switch sensor 28 is installed on the encoder bracket 21. When there is a knot on the rope, the upper guide wheel 26 of the encoder will jump upward when it encounters the knotted protrusion. The proximity switch sensor will capture the signal change and then send it to the controller.

[0055] The fixed-point clamping mechanism 3 includes a first column 31 fixedly mounted on the first frame 10, a clamping claw cylinder 32 is mounted on the first column 31, and the clamping claw cylinder 32 is driven and connected to a pair of clamping claws 33;

[0056] The fixed-point clamping mechanism 3 and the clamp tail translation assembly 52 are respectively located on the left and right sides of the cutting position. Before cutting the rope, the two sides of the breaking point are clamped to prevent the two ends of the rope from falling off during cutting. After cutting, the left end of the rope is still clamped by the fixed-point clamping mechanism, which is convenient for the subsequent clamp head translation assembly to clamp the rope for traction (the fixed-point clamping mechanism will be loosened only after the traction end is clamped). The right end of the rope is clamped by the clamp tail translation assembly and then translated close to the pulled end of the rope (short section).

[0057] The cutting mechanism 4 includes a first slide 41 arranged adjacent to the fixed-point clamping mechanism. The first slide 41 is slidably connected to the first frame. A cutting cylinder 42 is installed on the upper end of the first slide 41. The cutting cylinder 42 drives a movable knife plate 43 to move up and down along the Z-axis direction. A fixed knife plate 44 is installed below the movable knife plate 43. A heating element 45 is installed on the movable knife plate 43 or the fixed knife plate 44. A Y-axis cylinder 46 is installed below the first slide, and the Y-axis cylinder 46 drives the first slide 41 to move along the Y-axis direction.

[0058] The cutting mechanism can slide along the Y axis. When cutting is required, the cutting mechanism moves along the Y axis toward the direction of the rope. After cutting, it automatically resets to avoid interfering with the movement of other mechanisms. A heating element is installed on the movable blade or the fixed blade. Since the rope is easily scattered at the cut position (the fibers are easy to spread), it is necessary to use a hot knife to cut it. At the same time, there is a certain heat melting effect, which makes the fibers condense together to avoid loose fibers. When cutting, the movable blade is driven by the cutting cylinder to cut the rope with the cooperation of the fixed blade.

[0059] The rope pulling mechanism 5 is arranged at the adjacent side of the cutting mechanism 4, and includes a first mounting plate 15 fixedly mounted on the first frame 10, a clamp head translation assembly 53 and a clamp tail translation assembly 52 are arranged on the first mounting plate 51, and the clamp tail translation assembly 52 includes a first X-axis linear module 521 mounted on the first mounting plate 51, the first X-axis linear module 521 drives a first translation slide 522 to move along the X-axis direction, a first Z-axis cylinder 523 is mounted on the first translation slide 522, the first Z-axis cylinder 523 is driven and connected to a first rotating cylinder 524 along the Z-axis direction, and the first rotating cylinder 524 is driven and connected to a first clamping jaw cylinder 525;

[0060] The chuck translation assembly 53 includes a second X-axis linear module 531 mounted on the first mounting plate 51, the second X-axis linear module 531 drives the second translation slide 532 to move along the X-axis direction, the second translation slide 532 is mounted with a second rotary cylinder 533, and the second rotary cylinder 533 drives and connects to the second clamping jaw cylinder 534. Compared with the chuck translation assembly 53, the tail translation assembly 52 has an additional Z-axis movement, which is convenient for avoiding during translation.

[0061] The rope pulling mechanism 5 is used to pull the rope at the same distance each time along the X-axis direction, so as to facilitate cutting into equal lengths. After cutting, the tail clamp translation assembly will clamp one end of the rope and translate to the side of the clamp translation assembly. At this time, the rope head and the rope tail are facing forward and backward respectively, and then the clamping mechanism comes over to clamp the front and back ends of the rope respectively and clamp the rope to the fixture; after each cutting and clamping, the rope on the clamp translation assembly is cleared, and the clamp translation assembly 53 will move to the vicinity of the fixed-point clamping mechanism 3 to clamp the end of the rope, and then the fixed-point clamping mechanism 3 will be released, and the clamp translation assembly 53 will pull the end and stretch another length to be cut. Then the tail clamp translation assembly 52 comes over and clamps the tail end of the rope, and the fixed-point clamping mechanism 3 clamps at the same time, and then the cutting mechanism starts cutting.

[0062] The fixed-length mechanism 6 includes a vertical plate fixedly installed on the first frame, and a first Y-axis telescopic cylinder 61 is fixedly installed on the vertical plate. The first Y-axis telescopic cylinder 61 drives a pair of upper telescopic rods 61A to move along the Y-axis direction. A lifting platform 62 that can move up and down is arranged below the pair of upper telescopic rods 61A, and a second Y-axis telescopic cylinder 62A is installed on the lifting platform 62. The second Y-axis telescopic cylinder 62A drives a pair of lower telescopic rods 62B to move along the Y-axis direction. The lifting platform 62 is slidably connected to a pair of vertical rails 63 installed on the vertical plate. A driving belt 64 is arranged on one side of the vertical rail 63. The driving belt 64 is connected to the lifting motor 65 for transmission. The lifting motor installed on the vertical plate drives the lifting platform to move up and down.

[0063] When the preset cutting length is less than the maximum translation stroke of the chuck translation assembly, the fixed length mechanism does not work during this process;

[0064] When the preset cutting length is greater than the maximum translation stroke of the chuck translation assembly, even if the chuck translation assembly 53 pulls the rope and moves to the maximum stroke position, it cannot reach the required cutting length. At this time, the fixed-length mechanism needs to intervene, and the upper telescopic rod 61A and the lower telescopic rod 62B extend out and hang on the upper and lower sides of the rope. Then the lifting motor 65 drives the lower telescopic rod 62B to move downward, so that the rope forms a certain bend. In this way, when the preset cutting length is reached, the clamp tail translation assembly 52 and the fixed-point clamping mechanism 3 clamp it for cutting.

[0065] The clamping mechanism 7 includes a second frame 20, which is arranged on the adjacent side of the first frame. A Y-axis linear module 71 is installed on the second frame. The Y-axis linear module 71 is driven and connected to a Y-axis bracket 72 that can slide along the Y-axis direction. An X-axis cylinder 73 is installed on the Y-axis bracket 72. The X-axis cylinder 73 is driven and connected to a Z-axis cylinder 74 that can slide along the X-axis direction. The Z-axis cylinder 74 is driven and connected to a third rotary cylinder 75 that can move along the Z-axis direction. The cylinder body of the third rotary cylinder 75 is fixedly connected to a third clamping claw cylinder 76. The third rotary cylinder 75 is driven and connected to a fourth rotary cylinder 77. The fourth rotary cylinder 77 is driven and connected to a fourth clamping claw cylinder 78.

[0066] When the two ends of the rope cut into small sections are clamped by the clamping head translation assembly and the clamping tail translation assembly respectively, the third clamping jaw cylinder 76 and the fourth clamping jaw cylinder 77 of the clamping mechanism come over to clamp the two ends of the rope respectively, and then the clamping head translation assembly and the clamping tail translation assembly are released and moved away, and then the third rotating cylinder 76 drives the fourth clamping jaw cylinder to swing 90 degrees, and then the fourth rotating cylinder drives the fourth clamping jaw cylinder to swing 90 degrees automatically, and finally the two ends of the rope face the same direction, which is convenient for clamping on the fixture.

[0067] The fixture conveying mechanism 8 includes an empty tray conveying assembly 8A and a full tray conveying assembly 8B which are installed in the second frame 20 and are arranged in an upper and lower manner;

[0068] A fixture handling assembly 9 is arranged above the empty tray conveying assembly 8A. The fixture handling assembly 9 comprises a first horizontal frame 91 slidably connected to the second frame. The first horizontal frame 91 is driven by an X-axis cylinder 92 and can move along the X-axis direction. A Z-axis cylinder 93 is installed on the first horizontal frame 91. The Z-axis cylinder 93 is driven to connect a second horizontal frame 94 that can move along the Z-axis direction. Two clamping block cylinders 95 are installed at both ends of the second horizontal frame 94. The fixture handling assembly 9 is used to carry the empty fixtures conveyed by the empty tray conveying assembly 8A to the clamping station at one end of the full tray conveying assembly 8B;

[0069] The empty tray conveying assembly 8A and the full tray conveying assembly 8B both include two sets of relatively arranged conveying belts driven by motors, on which N blocks 82 are fixedly connected at equal intervals, and one end of the empty tray conveying assembly 8A and the full tray conveying assembly 8B is provided with a pair of limiting cylinders 81.

[0070] The clamp 80 includes a clamp profile 80A and M groups of spring clips 80B fixedly connected to the upper end surface of the clamp profile 80A. The two ends of the M groups of ropes are respectively clamped in the M groups of spring clips 80B.

[0071] The empty tray conveying assembly conveys the empty fixture from right to left. When the fixture at the far left is limited, the two clamping cylinders of the fixture transporting assembly clamp the two ends of the empty fixture respectively, and then place it in the clamping station on the lower level. When the fixture at the clamping station is filled with ropes, the full tray conveying assembly outputs it to the right.

[0072] Working principle: Fig.15 As shown, when the preset cutting length is less than the maximum translation stroke of the chuck translation assembly, the following is a position state diagram and a working step diagram of the related mechanism:

[0073] A: The clamp translation assembly 53 stops after the pulling rope head end reaches the preset distance;

[0074] B: The clamp tail translation assembly 52 and the fixed point clamping mechanism 3 clamp the other end of the rope;

[0075] C: The cutting mechanism 4 is actuated to cut the rope;

[0076] D: The rope is cut into small sections, and the head and tail ends of the sections are clamped respectively;

[0077] E: The clamp tail translation assembly 52 clamps the tail end of the rope and moves close to the clamp head translation assembly 53;

[0078] F: The tail clamp translation assembly 52 clamps the tail end of the rope and flips it 180 degrees, so that the tail and head of the rope face the same direction; then the clamping mechanism 7 clamps the head and tail ends of the rope respectively and places them on the fixture;

[0079] G: The chuck translation assembly 53 moves and returns to the vicinity of the fixed-point clamping mechanism 3 to clamp a new end;

[0080] H: The fixed-point clamping mechanism 3 is released and the chuck translation assembly 53 is pulled back to the position of state A to carry out the next cycle.

[0081] When the preset cutting length is greater than the maximum translation stroke of the chuck translation assembly, even if the chuck translation assembly 53 moves to the maximum translation stroke, it still cannot meet the cutting length. At this time, the fixed length mechanism 6 will cause interference between A and B, such as Fig.16 As shown, the specific process is: the upper telescopic rod 61A and the lower telescopic rod 62B extend out and hook the upper and lower sides of the rope (such as state AB1), and then the lifting motor 65 drives the lower telescopic rod 62B to move downward and pulls the rope to bend. When the length of the bent rope reaches the cutting length (such as state AB2), the tail clamp translation assembly 52 and the fixed-point clamping mechanism 3 clamp the other end of the rope, and return to step B in the above process AH steps to cycle.
