Description

Technical Field

[0001] The utility model belongs to the technical field of zipper production equipment, and particularly relates to a zipper carrying mechanism. Background Art

[0002] On a zipper production line, a long string of zippers is typically cut into individual, complete product segments. A zipper cutter is an automated device that cuts a long string of zippers into individual, complete product segments. Existing zipper cutters typically use a conveyor belt to transport the zippers to a storage area or hopper to prevent the cut zippers from accumulating in the cutting area and hindering subsequent cutting. Furthermore, the conveyor belt removes the zippers from the cutting area, facilitating manual or automated packaging.

[0003] While conveyor belts can carry zippers away from the cutting area, they can become skewed as they are carried, causing them to fall into the hopper without maintaining a horizontal position. This can lead to zipper accumulation in the hopper, especially for long zippers and when the cutting machine is cutting quickly. Each zipper section falls into the hopper in a horizontal position, stacking one after another in an orderly manner, creating a neat arrangement that facilitates subsequent manual or automatic packaging. Zipper accumulation in the hopper occurs when zippers are stacked without a specific pattern or sequence, potentially resulting in disordered shapes and alignment, making subsequent processing or packaging more difficult and reducing work efficiency.

[0004] Furthermore, there's a gap between the hopper's receiving plate and the conveyor belt. Zippers falling from the conveyor belt can get stuck in this gap, damaging them. While placing the receiving plate at the bottom of the conveyor belt prevents zippers from getting stuck in the gap, the height difference between the conveyor belt and the receiving plate forces the zipper to fall freely onto the receiving plate. This free-falling zipper increases the risk of zipper skew and makes it difficult to maintain the correct position of the zipper after it falls, increasing the risk of zipper accumulation.

[0005] For example, the zipper cutting machine disclosed in the authorization announcement number CN210589605U includes a frame, a belt pulling device and a belt cutting device. The frame is provided with a belt support frame, and the belt support frame is provided with an image detection device. The belt pulling device and the belt cutting device are arranged on the frame and are located at the end of the belt support frame. The end of the belt cutting device is provided with a storage bin, and the storage bin is provided with a finished product area, a waste area, a partition and a pushing cylinder for pushing the partition. The partition is movably arranged on the frame, and the pushing cylinder is fixed on the frame. The output end of the pushing cylinder is connected to the partition to push the partition so that the finished product area or the waste area is connected to the end of the belt cutting device; a conveyor belt is provided below the belt pulling device, and the end of the conveyor belt is located above the storage bin. The conveyor belt is located above the storage bin. The cut zipper falls on the conveyor belt. The conveyor belt transports the zipper and drops it onto the partition (the above-mentioned receiving plate). The zipper slides through the partition and into the storage bin. There is a height difference between the zipper landing point on the conveyor belt and the zipper receiving point on the partition. The zipper needs to fall freely to the partition.

[0006] For example, in the patent application filed in China with application number 202422286655.1, a conveying device for a zipper detection and cutting machine is disclosed, comprising a conveying plate with movable parts installed on both sides of the conveying plate. A movable part at the front end is installed on a front mounting seat, which is installed on a receiving plate. Two movable parts at the rear end are installed on a rear mounting seat, which is movably connected to the rear mounting seat via a rotating shaft. The three movable parts all move on a guide rail, which is arranged on a fixed plate. The guide rail consists of a first guide rail section and a second guide rail section. The first guide rail section is horizontal or approximately horizontal, so that the receiving plate maintains horizontal or approximately horizontal movement. The second guide rail section is downwardly inclined. When the driving assembly drives the receiving plate to move to the second guide rail section, the receiving plate tilts and the zipper on the receiving plate falls. The front and rear mounting seats are connected to the sides of the carrier plate and are exposed between the carrier plate and the fixed plate. Furthermore, a large gap exists between the carrier plate and the fixed plate where the front and rear mounting seats are not installed. In this case, when the zipper falls between the carrier plate and the fixed plate, it will get stuck between the mounting seat and the rear mounting seat, or in the gap between the carrier plate and the fixed plate, affecting the zipper's falling posture, causing the zipper to accumulate, and in severe cases, damage the zipper. When the zipper needs to be pulled toward the carrier plate after being cut, it passes through the mounting seat, which can easily scratch the zipper, increasing the production cost of the zipper. Utility Model Content

[0007] The purpose of the utility model is to provide a zipper carrying mechanism, which can not only ensure the smoothness of the zipper carrying surface and avoid the zipper from getting stuck, but also can move the zipper carrying belt away from the zipper cutting work area, so that the zippers can slide smoothly to a horizontal and neatly stacked state, which is convenient for manual or automatic packaging of the zippers.

[0008] In order to achieve the above technical purpose, the technical solution of the utility model is:

[0009] The zipper carrying mechanism includes a push plate, which is used to carry the zipper, and sliding components are provided on both sides of the push plate, and the sliding components include guide rails and slide bars, and there are brackets on both sides of the push plate, and the guide rails are located on the brackets, and the slide bars are arranged at the bottom of the push plate, and the side edges of the push plate are close to or cover the brackets, and the slide bars include a first slide bar and a second slide bar, and the first slide bar is located in front of the second slide bar, and the first slide bar and the second slide bar slide on the guide rails, and the guide rails include a push plate translation section and a push plate flipping section, and the push plate is provided with a pushing component, and the pushing component drives the push plate to make the first slide bar and the second slide bar slide on the guide rails. When the first slide bar slides in the push plate flipping section, the push plate tilts, and the zipper on the push plate will slide off the push plate.

[0010] The drawstring mechanism pulls the zipper over the push plate, where the cutter cuts one end of the zipper and the drawstring mechanism releases the other end, allowing the zipper to fall onto the push plate. The push assembly drives the push plate, and the slide bars on either side of the push plate slide on guide rails. When the first slide bar slides to the push plate's tilting section, it deflects the movement of the first slide bar from the push plate's translational section, causing the push plate to tilt. When the push plate tilts to a certain angle, the zipper slides off the push plate into the hopper, preventing the zipper from free-falling in front of the hopper and allowing the zipper to slide smoothly into a horizontal, neatly stacked state. After the push plate completes its tilt, the push assembly resets the push plate.

[0011] The sliding rod is set at the bottom of the push plate, which can make the edge of the push plate close to the bracket or cover the top of the bracket, reduce the gap between the push plate and the bracket, and block the sliding rod at the bottom of the push plate and the guide rail for the sliding rod to ensure the smoothness of the push plate zipper carrying surface, avoid zipper jamming, and reduce the possibility of zipper damage.

[0012] The push plate translation section is a straight guide rail, and the push plate flipping section is a downwardly inclined extension section of the straight guide rail.

[0013] A first slide is provided at the bottom of each of the left and right sides of the push plate. The first slide is connected to a second slide via a slide shaft. The first slide is provided on the first slide, and the second slide is provided on the second slide. The second slide and the first slide rotate about the slide shaft. The second slide is provided with a third slide, which slides on a guide rail. Adding the third slide to the second slide facilitates the movement of the second slide on the guide rail and facilitates the tilting movement of the push plate, thereby improving the stability of the push plate.

[0014] The second slide bar is a slide shaft, and the first slide and the second slide are rotatably connected via the second slide bar.

[0015] The pushing assembly pushes the second slide to drive the push plate to move.

[0016] The pushing assembly includes a slider and a power device (cylinder). The slider is arranged on a slider rail and slides. The slider is connected to a second slide seat. The power device drives the slider to slide on the slider rail. The slider drives the second slide seat to make the first slide bar, the second slide bar and the third slide bar slide on the guide rail, thereby realizing the pushing assembly driving the push plate.

[0017] The bracket is located between the second slide seat and the slider rail, and the slider is connected to the second slide seat through a connecting block.

[0018] The second sliding seat of the left sliding assembly and the second sliding seat of the right sliding assembly are connected by a power connecting rod. When the pushing assembly drives one of the second sliding seats, the power connecting rod is used to transmit power to the other second sliding seat.

[0019] The utility model can not only move the zipper carrier away from the zipper cutting work area by moving the flipping push plate, but also make the zippers slide smoothly to a horizontal and neatly stacked state, so as to facilitate manual or automatic packaging of the zippers.

[0020] The utility model can not only make way for the zipper lower surface detection device to detect the zipper lower surface and ensure the zipper quality through the movable push plate, but also can take the zipper away from the zipper detection area to realize the sorting of zippers.

[0021] The utility model sets the push plate on the top of the slide, so that the edge of the push plate is close to the bracket or covers the top of the bracket, ensuring a smooth zipper carrying surface, avoiding zipper jams and reducing the possibility of zipper damage. At the same time, it also makes it easier for the push plate to carry long zippers (zippers whose length is greater than the distance between the left and right brackets), improving the applicability of the carrying mechanism.

[0026] like Figure 1-3 As shown, the zipper carrying mechanism includes a push plate 4, and sliding components are respectively provided on both sides of the push plate, wherein the sliding component located on the left is the left sliding component, and the sliding component located on the right is the right sliding component.

[0027] The left sliding assembly includes a left guide rail and a left slide bar. The left guide rail is mounted on the left bracket 5. The left guide rail includes a left push plate translation section 51 and a left push plate flip section 52. The left push plate translation section 51 is a straight guide rail hole, while the left push plate flip section 52 is a downwardly inclined extension of the straight guide rail hole. The left slide bar includes a first left slide bar 56, a second left slide bar 55, and a third left slide bar 57. The second left slide bar 55 is located between the first and third left slide bars 56, 57, with the first left slide bar 56 located at the front. The first, second, and third left slide bars 56, 55, 57 all slide within the left guide rail. A first left-side slide 56 is mounted on the first left-side slide 53, which is connected to the bottom of the push plate 4. A second left-side slide 55 and a third left-side slide 57 are mounted on the second left-side slide 54. The second left-side slide 54 is rotatably connected to the first left-side slide 53 via the second left-side slide 55. The second left-side slide 54 and the first left-side slide 53 rotate about the second left-side slide 55, with the edge of the push plate 4 approaching the left bracket 5. The first, second, and third left-side slides 56, 55, and 57 are each equipped with rollers or bearings to reduce friction between the left slides and the left guide rail.

[0028] The right sliding assembly includes a right guide rail and a right slide bar. The right guide rail is mounted on the right bracket 6. The right guide rail includes a right push plate translation section 61 and a right push plate flip section 62. The right push plate translation section 61 is a straight guide rail hole, while the right push plate flip section 62 is a downwardly inclined extension of the straight guide rail hole. The right slide bar includes a first right slide bar 66, a second right slide bar 65, and a third right slide bar 67. The second right slide bar 65 is located between the first and third right slide bars 66, 67, with the first right slide bar 66 located at the front. The first, second, and third right slide bars 66, 65, and 67 all slide within the right guide rail. The first right-side slide 66 is mounted on the first right-side slide 63, which is connected to the bottom of the push plate 4. The second right-side slide 65 and the third right-side slide 67 are mounted on the second right-side slide 64. The second right-side slide 64 is rotatably connected to the first right-side slide 63 via the second right-side slide 65. The second right-side slide 64 and the first right-side slide 63 rotate about the second right-side slide 65. The second right-side slide 65 and the second left-side slide 55 are coaxially arranged, and the edge of the push plate 4 covers the right bracket 6. The first right-side slide 66, the second right-side slide 65, and the third right-side slide 67 are all equipped with rollers or bearings to reduce the friction coefficient between the right-side slides and the right guide rail.

[0029] The right sliding assembly is provided with a pushing assembly, which includes a cylinder 8 and a slider 81. The slider 81 is slidingly set on the slider rail 82, and the slider rail 82 is set on the right bracket 6. The slider 81 slides on the right bracket 6 along the slider rail 82. The second right slide 64 and the slider rail 82 are respectively located on both sides of the right bracket 6. The slider 81 is connected to the second right slide 64 through the connecting block 83. The cylinder 8 drives the slider 81 to slide along the slider rail 82 on the right bracket 6. The slider 81 drives the second right slide 64 through the connecting block 83, so that the pushing assembly drives the push plate 4, so that the first right slide bar 66, the second right slide bar 65 and the third right slide bar 67 slide along the right guide rail.

[0030] The second right slide 64 and the second left slide 54 are connected via a power connecting rod 84 , and the power connecting rod 84 transmits the power of the second right slide 64 to the second left slide 54 .

[0031] The cylinder 8 drives the slider 81 to slide along the slider rail 82 toward the push plate flip section 62, the first right slide bar 66, the second right slide bar 65 and the third right slide bar 67 slide along the right guide rail, and the first left slide bar 56, the second left slide bar 55 and the third left slide bar 57 slide along the left guide rail. When the first right slide bar 66 and the first left slide bar 56 enter the push plate flip section, since the push plate flip section is a downwardly inclined extension of the straight guide rail hole, the first right slide bar 66 and the first left slide bar 56 deviate from the movement trajectory of the push plate translation section. The second right slide 64 and the first right slide 63 rotate about the second right slide bar 65, and the second left slide 54 and the first left slide 53 rotate about the second left slide bar 55, and the push plate 4 begins to tilt. When the push plate 4 tilts to a certain angle, the zippers will slide smoothly from the push plate 4 into the hopper, forming a horizontal and neat stack inside the hopper, preventing the zippers from free falling in front of the hopper and getting stuck in the gap between the conveyor belt and the hopper receiving plate. After the push plate 4 completes its tilt, the cylinder resets, and the first right slide bar and the first left slide bar return to the push plate translation section, thereby restoring the push plate 4.

[0032] On the right side of the bracket 6, the left push plate 4 has a downwardly curved push plate extension 41 at its end. The push plate 4 and the push plate extension 41 shield the various components at its bottom, ensuring a smooth zipper-carrying surface and preventing damage to the zipper. Furthermore, covering the zipper on top of the right bracket 6 facilitates the push plate's ability to carry long zippers (zippers longer than the push plate or longer than the distance between the right bracket and the left bracket), improving the applicability of the carrying mechanism.

[0033] When using:

[0034] The zipper carrier mechanism is located downstream of the tape cutting device. The tape drawing device pulls the zipper onto the zipper carrier mechanism's push plate 4. After the tape drawing device pulls the zipper onto the push plate 4, the tape cutting device cuts the zipper, and the zipper end falls onto the push plate 4. The zipper device releases the zipper (which can occur simultaneously with the cutting device), and the entire zipper falls onto the push plate 4. After the zipper falls onto the push plate 4, the cylinder drives the push plate 4, and the push plate 4 continues to move along the push plate translation section. When the first right slide bar 66 and the first left slide bar 56 simultaneously enter the push plate flip section, because the push plate flip section is a downward-inclined extension of the straight guide rail hole, the first right slide bar 66 and the first left slide bar 56 deviate from the movement trajectory of the push plate translation section, causing the push plate 4 to begin tilting, and the zipper will slide from the push plate 4 into the hopper 9. After the zipper slides off the push plate 4, the cylinder drives the push plate 4 to reset, entering the next working cycle.

[0035] This embodiment can not only move the zipper carrier away from the zipper cutting work area by moving the flipped push plate, but also make the zippers slide smoothly to a horizontal and neatly stacked state, which is convenient for manual or automatic packaging of the zippers.

[0036] In this embodiment, the push plate is set on the top of the right slide seat, covering the top of the right bracket and extending outward to shield the components at the bottom of the push plate, ensuring the smoothness of the zipper carrying surface, avoiding zipper jamming, and reducing the possibility of zipper damage. At the same time, it is also convenient for the push plate to carry long zippers, thereby improving the applicability of the carrying mechanism.

[0037] As another embodiment, the zipper carrying mechanism and the zipper lower surface detection device are arranged downstream of the tape cutting device. The zipper lower surface detection device is used to detect the lower surface of the zipper. The zipper carrying mechanism is used to carry the zipper above the zipper lower surface detection device, and the tape drawing device pulls the zipper to the top of the zipper lower surface detection device. During use, the tape drawing device pulls the zipper to the top of the zipper lower surface detection device, and the zipper lower surface detection device detects the lower surface of the zipper. After the zipper lower surface detection is completed, the cylinder drives the push plate 4, and the push plate 4 extends along the push plate translation section between the zipper and the zipper lower surface detection device. After the push plate 4 extends into the bottom of the zipper, the cutting device 1 cuts the zipper, and the zipper end falls on the push plate 4.

[0038] For zippers that pass the inspection, the drawstring device releases the zipper (which can be done simultaneously with the cutting device), and the entire zipper falls onto the push plate 4. After the zipper falls onto the push plate 4, the cylinder drives the push plate 4, and the push plate 4 continues to move along the push plate translation section. When the first right slide bar 66 and the first left slide bar 56 simultaneously enter the push plate flip section, since the push plate flip section is a downward-inclined extension of the straight guide rail hole, the first right slide bar 66 and the first left slide bar 56 deviate from the movement trajectory of the push plate translation section, and the push plate 4 begins to tilt, and the zipper will slide off the push plate 4. After the zipper slides off the push plate 4, the cylinder drives the push plate 4 to reset, and enter the next working cycle.

[0039] For the zipper that fails the inspection, the drawstring device continues to pull the zipper, and the zipper passes through the push plate extension portion 41 and separates from the zipper carrying mechanism.

[0040] In this embodiment, the movable push plate can not only make way for the zipper lower surface detection device to detect the zipper lower surface to ensure the quality of the zipper, but also can take the zipper away from the zipper detection area to achieve zipper sorting.

[0041] As another embodiment, the pushing component at the right sliding component can also be provided at the left sliding component, and the pushing component drives the second left sliding seat 54 to slide, so as to realize the movement of the push plate.

[0042] As another embodiment, a pushing assembly may be provided at both the right sliding assembly and the left sliding assembly to realize the movement of the push plate.

[0043] The above embodiments do not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
