Abstract
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, both ends of the ropes are generally coated with glue to prevent them from loosening. Our 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 ropes (that is, the rope fixing device in the patent specification) into the glue for dipping (or soaking head). When the glue completely covers the rope end, it is taken out and then the glue 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 employees use their hands to clamp the cut ropes one by one on the fixture to form a neat arrangement, and then dip them in glue. This clamping operation is inefficient, and the current labor 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 clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0041] See also Figures 1 to 14 As shown, the present invention provides a technical solution: including 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 as 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 lengths;
[0046] The fixed-point clamping mechanism 3 is used to intermittently clamp the rope to facilitate cutting by the cutting mechanism;
[0047] The length fixing mechanism 6 is used to stretch the rope longitudinally when the preset length is greater than the pulling length, so that the rope can reach the preset length when it is pulled to the farthest end;
[0048] The clamping mechanism 7 is used to place 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 transported 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.
[0050] The rope straightening mechanism 1 includes 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 and the second straightening component 12 are synchronously driven and connected.
[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 driven and connected to a straightening drum 11B, the output shaft of the straightening motor 11A is connected to a first synchronous wheel 12C, the first synchronous wheel 12C is connected to a second synchronous wheel 12D through a belt, the second synchronous wheel 12D is connected to a swing arm 12B through 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 connected to it.
[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. The encoder upper guide wheel 26 is coaxially connected to an encoder 27. A proximity switch sensor 28 for detecting rope knots is mounted on the encoder bracket. Two support guide wheels 29 are mounted on each side of the length measuring mechanism 2.
[0054] The rope passes between the lower encoder guide wheel 24 and the upper encoder guide wheel 26, causing them to rotate. Because the upper encoder guide wheel 24 is connected to the encoder 27, the length of the rope passing through is automatically measured. A proximity switch sensor 28 is also mounted on the encoder bracket 21. When a knot appears in the rope, the upper encoder guide wheel 26 will jump upward when it encounters the knotted protrusion. The proximity switch sensor captures the change in signal and sends 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 cylinder 32 is mounted on the first column 31, and the clamping cylinder 32 is driven by a pair of clamping jaws 33;
[0056] The fixed-point clamping mechanism 3 and the clamping 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 clamping 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 clamping tail translation assembly and then translated close to the pulled end of the rope (small 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. The Y-axis cylinder 46 drives the first slide 41 to move along the Y-axis direction.
[0058] The cutting mechanism slides along the Y-axis. When cutting is required, it moves along the Y-axis toward the rope and automatically resets after cutting, preventing interference with the movement of other mechanisms. A heating element is installed on either the movable or fixed blade. Because the rope is prone to fraying at the cut point (fibers tend to scatter), a hot knife is used for cutting. This simultaneous heat-melting effect causes the fibers to coalesce and prevent fraying. During cutting, a cutting cylinder drives the movable blade, which cooperates with the fixed blade to sever the rope.
[0059] The rope pulling mechanism 5 is arranged on the adjacent side of the cutting mechanism 4, and includes a first mounting plate 15 fixedly mounted on the first frame 10. The first mounting plate 51 is provided with a clamping head translation assembly 53 and a clamping tail translation assembly 52. The clamping 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. The first translation slide 522 is mounted with a first Z-axis cylinder 523. The first Z-axis cylinder 523 is connected to a first rotary cylinder 524 for driving along the Z-axis direction. The first rotary cylinder 524 is connected to a first clamping jaw cylinder 525 for driving.
[0060] The chuck translation assembly 53 includes a second X-axis linear module 531 mounted on the first mounting plate 51. This module drives a second translation slide 532 along the X-axis. A second rotary cylinder 533 is mounted on the second translation slide 532, which drives a second jaw cylinder 534. Compared to the chuck translation assembly 53, the tail translation assembly 52 has an additional Z-axis motion, facilitating avoidance during translation.
[0061] The rope-pulling mechanism 5 is used to pull the rope at the same distance along the X-axis each time, facilitating cutting into equal lengths. After cutting, the tail clamp translation assembly will clamp one end of the rope and translate it to the side of the chuck translation assembly. At this time, the rope head and tail are facing forward and backward respectively. The clamping mechanism then comes in to clamp the front and back ends of the rope and clamp it to the fixture. After each cut and clamping, the rope on the chuck translation assembly is cleared, and the chuck translation assembly 53 moves to the vicinity of the fixed-point clamping mechanism 3 to clamp the end of the rope. The fixed-point clamping mechanism 3 is then released, and the chuck translation assembly 53 pulls the end and stretches it to the next length to be cut. The tail clamp translation assembly 52 then comes in and clamps the tail end of the rope. The fixed-point clamping mechanism 3 clamps it simultaneously, and the cutting mechanism then begins cutting.
[0062] The fixed-length mechanism 6 includes a vertical plate fixedly mounted on the first frame, on which a first Y-axis telescopic cylinder 61 is fixedly mounted, which drives a pair of upper telescopic rods 61A to move along the Y-axis direction, and 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 mounted on the lifting platform 62, which drives a pair of lower telescopic rods 62B to move along the Y-axis direction, and the lifting platform 62 is slidably connected to a pair of vertical rails 63 mounted on the vertical plate, and a driving belt 64 is provided on one side of the vertical rail 63, which is connected to the driving belt 64 and the lifting motor 65, and the lifting platform is driven up and down by the lifting motor mounted on the vertical plate.
[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 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 the third clamping cylinder 76. The third rotary cylinder 75 is driven and connected to the fourth rotary cylinder 77. The fourth rotary cylinder 77 is driven and connected to the fourth clamping 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 loosened 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 automatically swing 90 degrees. 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 mounted on the second frame 20 and arranged in an upper and lower manner;
[0068] Above the empty tray conveyor assembly 8A is a fixture handling assembly 9, comprising a first cross-frame 91 slidably connected to a second frame. This cross-frame 91 is driven by an X-axis cylinder 92 for movement along the X-axis. A Z-axis cylinder 93 is mounted on this first cross-frame 91, which in turn drives a second cross-frame 94 for movement along the Z-axis. Two clamping cylinders 95 are mounted at each end of this second cross-frame 94. This fixture handling assembly 9 is used to transport empty fixtures delivered from the empty tray conveyor assembly 8A to a clamping station at one end of the full tray conveyor assembly 8B.
[0069] The empty tray conveying assembly 8A and the full tray conveying assembly 8B both include two sets of oppositely arranged conveyor belts driven by motors, with N blocks 82 fixedly connected to the conveyor belts at equal intervals. A pair of limiting cylinders 81 are provided at one end of the empty tray conveying assembly 8A and the full tray conveying assembly 8B.
[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 transports the empty fixtures 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 will output it to the right.
[0072] Working principle: Figure 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 tail clamp 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 segments, and the head and tail ends of the segments are clamped separately;
[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 proceed to 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 the above A and B, such as Figure 16 As shown, the specific process is: the upper telescopic rod 61A and the lower telescopic rod 62B extend 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 clamping translation component 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.
[0082] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
