Description

Technical Field

[0001] The invention belongs to the technical field of zipper production equipment, and in particular relates to a zipper carrying mechanism. Background Art

[0002] In the zipper production line, a long string of zippers is usually cut into complete products. Zipper cutting machine is an automated device that cuts a long string of zippers into complete products. Existing zipper cutting machines usually use conveyor belts to carry zippers to the storage area or hopper to avoid the accumulation of cut zippers in the cutting work area, which affects the subsequent cutting of zippers; on the other hand, the conveyor belt takes the zippers away from the cutting work area, which is convenient for manual or automatic packaging of zippers.

[0003] Although the conveyor belt can take the zipper away from the cutting work area, the zipper will be skewed when the conveyor belt carries the zipper, and the zipper cannot be kept in a horizontal state and falls into the hopper, causing the zipper to accumulate in the hopper; especially for long zippers and when the cutting machine has a high cutting efficiency. Each section of the zipper remains horizontal and falls into the hopper in turn. The zippers can be stacked one by one in an orderly manner, presenting a neat arrangement. This stacking method is convenient for subsequent manual or automatic packaging. Zipper accumulation in the hopper means that the zippers are not stacked according to a certain rule or order, and may be stacked together in disorder, resulting in uneven shapes and arrangements, increasing the difficulty of subsequent processing or packaging, and reducing work efficiency.

[0004] On the other hand, there is a clearance gap between the receiving plate of the hopper and the conveyor belt. The zipper that falls from the conveyor belt may get stuck in the clearance gap, causing damage to the zipper. Although the receiving plate is set at the bottom of the conveyor belt to prevent the zipper from getting stuck in the clearance gap, there is a height difference between the conveyor belt and the receiving plate, and the zipper needs to fall freely onto the receiving plate. The free fall of the zipper will increase the possibility of the zipper being skewed, and it is also impossible to effectively ensure the zipper's falling posture, which increases the possibility of zipper accumulation.

[0005] For example, the zipper cutting machine disclosed in the authorization announcement number CN210589605U includes a frame, a strap pulling device and a strap cutting device. The frame is provided with a strap supporting frame, and the strap supporting frame is provided with an image detection device. The strap pulling device and the strap cutting device are arranged on the frame and are located at the end of the strap supporting frame. A material storage bin is arranged at the end of the strap cutting device. The material 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 strap cutting device; a conveyor belt is arranged below the strap pulling device, and the end of the conveyor belt is located above the material storage bin. The conveyor belt is located above the storage bin, and the cut zipper falls on the conveyor belt. The zipper transported by the conveyor belt falls on the partition (the above-mentioned receiving plate), and the zipper slides into the storage bin through the partition. There is a height difference between the zipper landing point of the conveyor belt and the zipper receiving point of the partition, and the zipper needs to fall freely to the partition.

[0006] For example, in the patent application with Chinese application number 202422286655.1, the conveying device for the zipper detection and cutting machine of the patent application includes a conveying plate, and movable parts are installed on both sides of the conveying plate. A movable part located at the front end is installed on the front mounting seat, and the front mounting seat is installed on the receiving plate. The two movable parts located at the rear end are installed on the rear mounting seat. The front mounting seat and the rear mounting seat are movably connected through a rotating shaft. The three movable parts all move on the guide rail, and the guide rail is set on the fixed plate. The guide rail is composed 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 component 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 mounting seat and the rear mounting seat are connected to the side of the carrier plate, and the front mounting seat and the rear mounting seat are exposed between the carrier plate and the fixed plate. In addition, there will be a large gap between the carrier plate and the fixed plate where the front mounting seat and the rear mounting seat are not installed. In this case, when the zipper falls between the carrier plate and the fixed plate, the zipper will be stuck between the mounting seat and the rear mounting seat or stuck in the gap between the carrier plate and the fixed plate, affecting the falling posture of the zipper, causing the accumulation of the zipper, and in severe cases, causing damage to the zipper. When the cut zipper needs to be pulled to the side of the carrier plate by the drawstring device, the zipper passes through the mounting seat, and the mounting seat is easy to scratch the zipper, increasing the production cost of the zipper. Summary of the invention

[0007] The purpose of the present invention is to provide a zipper carrying mechanism, which can not only ensure the smoothness of the zipper carrying plane 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 zipper can slide smoothly to a horizontal and neatly stacked state, which is convenient for manual or automatic packaging of the zipper.

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

[0009] The zipper carrying mechanism includes a push plate, which is used to carry the zipper, and sliding components are arranged on both sides of the push plate, and the sliding components include guide rails and slide rods. There are brackets on both sides of the push plate, and the guide rails are located on the brackets, and the slide rods are arranged at the bottom of the push plate. The side of the push plate is close to the bracket or covers the bracket, and the slide rods include a first slide rod and a second slide rod, and the first slide rod is located in front of the second slide rod, and the first slide rod and the second slide rod 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 rod and the second slide rod slide on the guide rails. When the first slide rod 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 device pulls the zipper to the top of the push plate, the tape cutting device cuts off one end of the zipper, and the drawstring device releases the other end of the zipper, and the zipper falls on the push plate; the push assembly drives the push plate, and the slide bars on both sides of the push plate slide on the guide rails respectively. When the first slide bar slides to the push plate flip section, the push plate begins to tilt due to the movement trajectory of the first slide bar offsetting the push plate translation section. When the push plate tilts to a certain angle, the zipper will slide from the push plate to the hopper, avoiding the free fall of the zipper in front of the hopper, and achieving the smooth sliding of the zipper to a horizontal and neatly stacked state. After the push plate completes the tilt, the push assembly drives the push plate to reset.

[0011] The sliding rod is set at the bottom of the push plate, so that the edge of the push plate can be close to the bracket or cover the top of the bracket, reducing the gap between the push plate and the bracket, and blocking 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] On the left and right sides of the push plate, the bottom of the push plate is provided with a first slide seat, the first slide seat is connected to the second slide seat through a slide seat rotating shaft, the first slide bar is provided on the first slide seat, the second slide bar is provided on the second slide seat, the second slide seat and the first slide seat rotate with the slide seat rotating shaft as the axis, the second slide seat is provided with a third slide bar, and the third slide bar slides on the guide rail. Adding the third slide bar to the second slide seat makes it easier for the second slide seat to walk on the guide rail, and also facilitates the tilting movement of the push plate, thereby improving the stability of the push plate.

[0014] The second slide bar is a slide seat rotation shaft, and the first slide seat and the second slide seat are rotationally connected through 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 to slide on the slider rail. The slider is connected to the 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 slide rail of the slider, and the slider is connected to the second slide seat through a connecting block.

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

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

[0020] The present invention can not only make way for the zipper lower surface detection device to detect the zipper lower surface to 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 the zippers.

[0021] The present invention sets the push plate on the top of the slide seat so that the edge of the push plate is close to the bracket or covers the upper part of the bracket, thereby ensuring the smoothness of the zipper carrying plane, avoiding the zipper from getting stuck, and reducing the possibility of zipper damage. At the same time, it is also convenient for the push plate to carry a long zipper (a zipper whose length is greater than the distance between the left and right brackets), thereby improving the applicability of the carrying mechanism.

The second left side slide seat 54 is rotatably connected to the first left side slide seat 53 through the second left side slide bar 55. The second left side slide seat 54 and the first left side slide seat 53 rotate with the second left side slide bar 55 as the axis, and the edge of the push plate 4 is close to the left bracket 5. The first left side slide bar 56, the second left side slide bar 55, and the third left side slide bar 57 are all provided with rollers or bearings to reduce the friction coefficient between the left side slide bar 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 arranged 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, and the right push plate flip section 62 is a downwardly inclined extension section 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 right slide bar 66 and the third right slide bar 67. The first right slide bar 66 is located at the front side. The first right slide bar 66, the second right slide bar 65 and the third right slide bar 67 all slide in the right guide rail. The first right side slide bar 66 is arranged on the first right side slide seat 63, the first right side slide seat 63 is connected to the bottom of the push plate 4, the second right side slide bar 65 and the third right side slide bar 67 are arranged on the second right side slide seat 64, the second right side slide seat 64 is rotatably connected to the first right side slide seat 63 through the second right side slide bar 65, the second right side slide seat 64 and the first right side slide seat 63 rotate with the second right side slide bar 65 as the axis, the second right side slide bar 65 and the second left side slide bar 55 are arranged coaxially, and the edge of the push plate 4 covers the right bracket 6. The first right side slide bar 66, the second right side slide bar 65 and the third right side slide bar 67 are all provided with rollers or bearings to reduce the friction coefficient between the right side slide bar and the right guide rail.

[0029] The right sliding assembly is provided with a pushing assembly, and the pushing assembly includes a cylinder 8 and a slider 81. The slider 81 is slidingly arranged on a slider rail 82, and the slider rail 82 is arranged on the right bracket 6. The slider 81 slides on the right bracket 6 along the slider rail 82. The second right slide seat 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 seat 64 through a connecting block 83. The cylinder 8 drives the slider 81 to slide on the right bracket 6 along the slider rail 82. The slider 81 drives the second right slide seat 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 flipping section, since the push plate flipping section is an extension section of the straight guide rail hole that tilts downward, the first right slide bar 66 and the first left slide bar 56 deviate from the motion trajectory of the push plate translation section, the second right slide seat 64 and the first right slide seat 63 rotate around the second right slide bar 65, the second left slide seat 54 and the first left slide seat 53 rotate around 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 zipper will slide smoothly from the push plate 4 to the hopper to present a horizontal and neatly stacked state in the hopper, avoiding the free fall of the zipper in front of the hopper and also avoiding the zipper from getting stuck in the gap between the conveyor belt and the hopper receiving plate. After the push plate 4 completes the tilting, the cylinder resets, and the first right slide bar and the first left slide bar reset back to the push plate translation section, thereby resetting the push plate 4.

[0032] On the right side of the bracket 6, the end of the left push plate 4 has a push plate extension 41 bent downward. The push plate 4 and the push plate extension 41 shield the various components at the bottom thereof, ensuring the smoothness of the zipper carrying plane and avoiding damage to the zipper. At the same time, the zipper is covered on the top of the right bracket 6, which also facilitates the push plate to carry a long zipper (a zipper longer than the push plate or a zipper longer than the length between the right bracket and the left bracket), thereby improving the applicability of the carrying mechanism.

[0033] When using:

[0034] The zipper conveying mechanism is arranged downstream of the tape cutting device, and the tape drawing device pulls the zipper onto the push plate 4 of the zipper conveying mechanism. After the tape drawing device pulls the zipper onto the push plate 4, the tape cutting device cuts the zipper, and the end of the zipper falls onto the push plate 4. The zipper device releases the zipper (which can be performed simultaneously with the cutting device), and the zipper falls onto the push plate 4 as a whole. 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 enter the push plate flip section synchronously, since the push plate flip section is an extension section of the straight guide rail hole that tilts downward, the first right slide bar 66 and the first left slide bar 56 deviate from the motion trajectory of the push plate translation section, and the push plate 4 begins to tilt, and the zipper will slide from the push plate 4 to the hopper 9. After the zipper slides off the push plate 4, the cylinder drives the push plate 4 to reset to enter 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, thereby 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 zipper lower surface, the zipper carrying mechanism is used to carry the zipper above the zipper lower surface detection device, and the belt drawing device pulls the zipper to the top of the zipper lower surface detection device. When in use, the belt drawing device pulls the zipper to the top of the zipper lower surface detection device, and the zipper lower surface detection device detects the zipper lower surface; after the zipper lower surface detection is completed, the cylinder drives the push plate 4, and the push plate 4 extends between the zipper and the zipper lower surface detection device along the push plate translation section; 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 the zipper that has passed the inspection, the drawstring device releases the zipper (which can be done simultaneously with the cutting device), and the zipper falls on the push plate 4 as a whole; after the zipper falls on 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 enter the push plate flip section synchronously, since the push plate flip section is an extension section of the straight guide rail hole that tilts downward, the first right slide bar 66 and the first left slide bar 56 deviate from the motion track 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 to enter the next working cycle.

[0039] For the unqualified zipper, the drawstring device continues to pull the zipper, and the zipper passes through the push plate extension portion 41 and is separated 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 zipper quality, 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 may also be disposed 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 the right sliding assembly and the left sliding assembly at the same time 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.
