A new type of crimping machine

Abstract

This utility model relates to the technical field of snap fastener machines, specifically a novel snap fastener machine, comprising a material storage assembly, a feeding assembly, and a snap fastener assembly. The feeding assembly includes a push rod, a turntable, and two suction components. The turntable is rotatable and has at least two stations for placing a set of fasteners, one of which is a feeding station located on one side of the push rod. The suction components are movable, thereby moving an upper or lower fastener to the front of the push rod. Simultaneously, the push rod is movable. Therefore, the turntable shortens the length of the push rod, reducing its back-and-forth movement time. Compared to back-and-forth pushing, the rotation time is shorter, thus reducing the overall time and improving the efficiency of the initial feeding. Furthermore, the multiple stations and the simultaneous movement of the snap fasteners and the push rod mean that the interval between two snap fastener presses is equal to the turntable's rotation time. Compared to back-and-forth pushing, the rotation time is shorter, further reducing the time between two snap fastener presses and improving efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of snap fasteners, and specifically to a new type of snap fastener. Background Technology

[0002] A snap fastener machine is a machine used to process woven bags. Its main function is to create openings in the woven bags and then snap fasteners onto the bags by pressing them together. The machine includes a feeding device, an opening device, a snap fastener device, and a discharging device. The snap fastener device further includes a storage component, a feeding component, and a snap fastener assembly. Existing feeding components use a push-feed method, where the upper and lower fasteners are pushed to the snap fastener assembly by a push rod. However, only one set of fasteners (one upper and one lower) is pushed at a time, and the push rod must return before the second set can be pushed. Furthermore, the snapping process only occurs after the push rod returns. Therefore, the entire process involves pushing, returning, and then snapping, requiring waiting for the push rod to move back and forth before each snapping operation, resulting in long working times and low efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a novel snap-fit ​​machine. By setting up a turntable, the length of the push rod is shortened, thereby reducing the time the push rod spends going back and forth. Compared to pushing back and forth, the rotation time is shorter, thus reducing the overall time and improving the efficiency of the initial feeding. Furthermore, the multiple workstations and the simultaneous movement of the snap-fit ​​machine and the push rod ensure that the interval between two snap-fits is equal to the turntable's rotation time. Compared to pushing back and forth, the rotation time is shorter, further reducing the time between two snap-fits and improving efficiency. Therefore, this invention solves the problem of low efficiency in push-feeding.

[0004] The purpose of this utility model is achieved as follows:

[0005] A novel snap fastener machine includes a storage assembly, a feeding assembly, and a snap fastener assembly, wherein the feeding assembly is located between the storage assembly and the snap fastener assembly. The feeding assembly includes a push rod, a turntable, and two suction components. The turntable is rotatable and has at least two stations for placing a set of fasteners. One of the stations is a feeding station located on one side of the push rod. The suction components are movable to suction the upper or lower fastener in the storage assembly and move the upper or lower fastener to the front of the push rod.

[0006] The push rod is movable. When there is a set of fasteners in front of the push rod, the push rod will push the set of fasteners to the feeding station and return to the initial position. At this time, the turntable starts to rotate and drives the set of fasteners to the snap fastening assembly. Another station will rotate to the front of the push rod. At this time, the snap fastening of the snap fastening assembly and the back-and-forth movement of the push rod work simultaneously, and the time between two snap fastenings is the time of the turntable rotation.

[0007] Preferably, the workstation is provided with two clamping members, and the clamping members include a clamping part one and a clamping part two, and the upper fastener or the lower fastener is located between the clamping part one and the clamping part two;

[0008] The snap fastener assembly includes a base and a movable pressing head. The base has an opening at the top and a second suction element is placed inside the opening. The second suction element is used to suction the lower fastener to restrict its movement. The pressing head is located above the middle of the upper fastener. The pressing head moves downward and pushes the upper fastener to move and connect with the lower fastener.

[0009] Preferably, the pressing head is located above the opening in the middle of the upper fastener, and after the pressing head moves down, it is located inside the opening of the upper fastener. The pressing head is provided with a movable push plate. When the upper fastener and the lower fastener are connected, the push plate moves down and pushes the upper fastener to disengage from the pressing head.

[0010] Or / and, the base is movable and moves simultaneously with the pressing head;

[0011] Or / and, an air blowing pipe is provided on one side of the base, and the air blowing pipe is used to blow away the problematic fastener.

[0012] Preferably, the turntable has four stations, namely a feeding station, a detection station, a snap-fitting station, and a pushing station. A detector is provided on one side of the detection station, and a pusher plate is provided above the pushing station. The snap-fitting station is adapted to the snap-fitting assembly for snap-fitting. The detector is used to detect whether the detection station has a set of fasteners. When no set of fasteners is detected, the turntable will move the fastener located at the detection station to the pushing station. At this time, the pusher plate moves down and pushes the upper or lower fastener.

[0013] Preferably, the storage assembly includes two storage areas, which are located on both sides of the push rod and are used for storing the upper fastener and the lower fastener respectively. Each storage area is provided with several movable seats, which are movable and provided with a placement rod. Several upper fasteners or lower fasteners are stacked together and sleeved on the outside of the placement rod.

[0014] One of the several movable seats is located at the material pick-up point, which is located below the adsorption component. Movable push plates and limiting plates are respectively provided on both sides of the movable seat at the material pick-up point, and the push plates are located below the lowermost upper or lower fastener at the material pick-up point.

[0015] When the upper or lower fastener at the top of the material pick-up area is attracted by the suction device, the push plate will move upward and push the remaining upper or lower fastener upward until the remaining upper or lower fastener is disengaged from the placement rod. At this time, the limiting plate will move to below the lowermost upper or lower fastener, and the limiting plate will move upward and push. The push plate will move backward and downward, and the next moving seat will move to the material pick-up area. At this time, the push plate will move to below the lowermost upper or lower fastener of the moving seat at the material pick-up area, and drive the upper or lower fastener on the moving seat to overlap with the remaining upper or lower fastener of the previous moving seat. At this time, the limiting plate will return to the initial position.

[0016] Preferably, the limiting plate has a groove, and when the limiting plate moves to below the lowermost upper or lower fastener, the push plate is located in the groove.

[0017] Or / and, the movable seat is provided with a limiting member on both sides of the placement rod, and the limiting member is used to abut against the lowermost upper or lower fastener, so that there is a gap between the movable seat and the lowermost upper or lower fastener.

[0018] Or / and, a plate is provided above the material taking point, and the plate has a hole in the middle so that the upper fastener or the lower fastener can pass through. The plate has a limiting member two on the inner wall of the hole, and the limiting member two is used to contact the outer wall of the upper fastener or the lower fastener so as to restrict the position of the upper fastener or the lower fastener.

[0019] Preferably, there are two push rods, each corresponding to an upper or lower fastener. One end of the push rod is connected to a drive source and moves under the drive of the drive source. The other end of the push rod is symmetrically provided with two snap-fit ​​parts. Each snap-fit ​​part has a snap-fit ​​groove, and the two ends of the upper or lower fastener are respectively located in the snap-fit ​​grooves of the two snap-fit ​​parts.

[0020] Preferably, the adsorption element is disposed on the rod, and the rod is connected to the ends of two connecting rods. The other end of the connecting rod is connected to a wheel, and the wheels of the two connecting rods rotate synchronously. The rotation of the wheel drives the end of the connecting rod connected to the wheel to rotate, and the other end of the connecting rod swings and drives the rod to move, thereby driving the adsorption element to move.

[0021] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0022] This invention shortens the length of the push rod by setting up a turntable, thereby reducing the time the push rod spends going back and forth. Compared to pushing back and forth, the rotation time is shorter, thus shortening the time and improving the efficiency of the initial feeding. At the same time, the setting of multiple workstations and the back-and-forth movement of the buckle and the push rod work simultaneously, so that the interval between two buckles is the time of the turntable rotation. Compared to pushing back and forth, the rotation time is shorter, thus shortening the time between two buckles and improving efficiency. Attached Figure Description

[0040] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0041] like Figures 1-12 As shown, a novel snap fastener machine includes a storage assembly 4, a feeding assembly 5, and a snap fastener assembly 7. The feeding assembly 5 is located between the storage assembly 4 and the snap fastener assembly 7. The feeding assembly 5 includes a push rod 51, a turntable 52, and two suction members 53. The turntable 52 is rotatable and has at least two stations for placing a set of fasteners. One of the stations is a feeding station located on one side of the push rod 51. The suction members 53 are movable to suction the upper or lower fastener in the storage assembly 4 and move the upper or lower fastener to the front of the push rod 51.

[0042] Meanwhile, push rod 51 is movable. Therefore, in actual use, when there is a set of fasteners in front of push rod 51, push rod 51 will push this set of fasteners to the feeding station and return to the initial position. At this time, turntable 52 starts to rotate and drives this set of fasteners to the snap fastening assembly 7. Another station will rotate to the front of push rod 51. At this time, the snap fastening of snap fastening assembly 7 and the back-and-forth movement of push rod 51 work simultaneously, and the time between two snap fastenings is the time of turntable 52 rotation.

[0043] The adsorption component 53 includes two adsorption heads to ensure adsorption, and the two adsorption components 53 will place a set of fasteners at the placement point, and the placement point is located on one side of the push rod 51. Therefore, the push rod 51 is initially located on the side of the placement point, and the entire working path of the push rod 51 is to first push a set of fasteners on the placement point to the feeding station, and then return to the initial position.

[0044] Therefore, by setting up the turntable 52, the length of the push rod 51 is shortened, thereby reducing the time for the push rod 51 to move back and forth. Moreover, compared to pushing back and forth, the rotation time is shorter, thus shortening the time and improving the efficiency of the initial feeding (the initial feeding is when the machine just starts running and there is nothing on the workstation). At the same time, the setting of multiple workstations and the back-and-forth movement of the buckle and the push rod 51 work simultaneously, so that the interval between two buckles is the time of the turntable rotation. Compared to pushing back and forth, the rotation time is shorter, thus shortening the time between two buckles and improving efficiency.

[0045] Secondly, both the woven bags from the perforation device and the snap fastening device move on the shelf, and a transport structure, namely a conventional belt conveyor, is provided below the shelf 8 for transporting the woven bags. However, since the transport structure is not the focus of protection, it will not be detailed in the attached drawings and will not be described in detail again. However, the shelf is equipped with a limiter 3 84, which limits the height of the woven bags transported from the perforation device 2, thus preventing incorrect bag height when transported to the snap fastening assembly 7. Furthermore, the shelf is equipped with an adsorption element 3 and a detector 3 on one side of the snap fastening assembly 7. The detector 3 detects that the woven bag has been transported to its designated position, and then the adsorption element 3 adsorbs the bag, thus limiting its movement and facilitating the snap fastening.

[0046] like Figures 2-4 As shown, two clamping parts 54 are provided on the workstation, and each clamping part 54 includes a first clamping part 541 and a second clamping part 542, with the upper or lower fastener located between the first clamping part 541 and the second clamping part 542. The first clamping part 541 is mounted on the turntable 52 by screws, and the second clamping part 542 is mounted on the turntable 52 by a shaft, thus allowing it to rotate. The two second clamping parts 542 of a set of fasteners are connected by a shaft. Therefore, when a set of fasteners enters, the second clamping part 542 will be forced open and, together with the first clamping part 541, will apply force to both sides of the upper or lower fastener to clamp it.

[0047] Meanwhile, the snap-on assembly 7 includes a base 71 and a movable pressing head 72. The base 71 has an opening at the top, and a second suction member 73 is placed in the opening. The second suction member 73 is used to hold the lower snap-on member, thereby restricting its movement. The pressing head 72 is located above the middle of the upper snap-on member. Therefore, in actual use, the pressing head 72 will move downwards and push the upper snap-on member to move and connect with the lower snap-on member. At the same time, the pressing head 72 is located above the middle of the upper snap-on member, so it will not interfere with the clamping member 54 when snapping on.

[0048] Furthermore, the pressing head 72 is located above the opening in the middle of the upper fastener, and after the pressing head 72 moves down, it is located inside the opening of the upper fastener. At the same time, the pressing head 72 is provided with a movable push plate 74. Therefore, in actual use, when the upper fastener and the lower fastener are connected, the push plate 74 moves down and pushes the upper fastener to disengage from the pressing head 72.

[0049] The pressing head 72 and the push plate 74 are driven by cylinders, and the connection between the upper and lower fasteners indicates that a set of fasteners has been set on the woven bag. Furthermore, the suction element 73 restricts the movement of the lower fastener, thus preventing poor fastening effect after movement. The push plate 74 also prevents the upper fastener from failing to detach from the pressing head.

[0050] Secondly, the base 71 is movable and moves simultaneously with the pressing head 72. The movement of the base 71 is achieved by connecting to a cylinder, thus allowing it to move under the cylinder's drive. Therefore, during pressing, it works in conjunction with the pressing head 72 to press down on a set of fasteners simultaneously. Additionally, there can be multiple adsorption components 73, such as three, to ensure effective adsorption and prevent movement.

[0051] like Figures 2-4 As shown, the turntable 52 has four stations, namely a feeding station, an inspection station, a snap-fitting station, and a pushing station. A detector 77 is installed on one side of the inspection station, and a pusher plate 76 is installed above the pushing station. The snap-fitting station is adapted to the snap-fitting assembly 7 for snap-fitting. The detector 77 is used to detect whether the inspection station has a set of fasteners. When no set of fasteners is detected, the turntable 52 will move the fastener located at the inspection station to the pushing station. At this time, the pusher plate 76 moves down and pushes the upper or lower fastener.

[0052] There are two detectors 77, which detect the upper fastener and the lower fastener respectively. The push plate 76 is driven by a cylinder and has a discharge pipe 761 below it. A detector 79 is set on one side of the push station and is used to detect whether it has moved to the push station so that the push plate 76 can move down.

[0053] Furthermore, an air blowing pipe 75 is provided on one side of the base 71, and the air blowing pipe 75 is used to blow away faulty fasteners. Faulty fasteners include those that were not detected at the inspection station and were only moved to the snap fastener assembly 7 with the lower fastener, or those that are snap fasteners but do not have woven bags.

[0054] like Figures 5-8As shown, the material storage assembly 4 includes two material storage areas, which are located on both sides of the push rod 51 and are used for storing materials for the upper and lower fasteners, respectively. Each material storage area is provided with several movable seats 41, and the movable seats 41 are movable and provided with placement rods 411. Several upper or lower fasteners are stacked together and sleeved on the outside of the placement rods 411. There are two placement rods 411, which are located in the openings in the middle of the upper or lower fasteners and restrict the horizontal movement of the upper or lower fasteners.

[0055] Meanwhile, one of the several movable seats 41 is located at the material pick-up point, which is located below the adsorption component 53. Movable push plates 42 and limiting plates 43 are respectively provided on both sides of the movable seat 41 located at the material pick-up point, and the push plate 42 is located below the lowermost upper fastener or lower fastener at the material pick-up point.

[0056] Therefore, in actual use, when the upper or lower fastener at the top of the material picking area is attracted away by the suction member 53, the push plate 42 will move upward and push the remaining upper or lower fastener upward until the remaining upper or lower fastener is disengaged from the placement rod 411. At this time, the limiting plate 43 will move to the bottom of the lowermost upper or lower fastener, and the limiting plate 43 will move upward and push, and the push plate 42 will move backward and downward. The next moving seat 41 will move to the material picking area. At this time, the push plate 42 will move to the bottom of the lowermost upper or lower fastener of the moving seat 41 at the material picking area, and drive the upper or lower fastener on the moving seat 41 to overlap with the remaining upper or lower fastener of the previous moving seat 41. At this time, the limiting plate 43 will return to the initial position.

[0057] The initial position is where the limiting plate 43 has not yet started working, i.e., it is located on one side of the upper or lower fastener, and this position will not affect the movement of the push plate 42 and the upper and lower fasteners. Furthermore, from the above scheme, the push plate 42 and the limiting plate 43 work together to stack the remaining upper or lower fasteners of the previous moving seat 41 with the upper or lower fasteners of the next moving seat 41. The movement and material handling of the push plate 42, the limiting plate 43, and the moving seat 41 are simultaneous, ensuring continuous material handling without any downtime or movement, thereby shortening the time and improving efficiency.

[0058] like Figure 7 As shown, the limiting plate 43 has a groove 431. When the limiting plate 43 moves to the bottom of the upper or lower fastener, the push plate 42 is located in the groove 431, thereby avoiding interference between the limiting plate 43 and the push plate 42.

[0059] Furthermore, the movable seat 41 is provided with limiting members 412 on both sides of the placement rod 411, and the limiting members 412 are used to abut against the bottom upper or lower fastener, so that there is a gap between the movable seat 41 and the bottom upper or lower fastener, thereby facilitating the push plate 42 to be located below the bottom upper or lower fastener.

[0060] Meanwhile, a plate 46 is provided above the material handling area, with a hole in the middle of the plate 46 to allow the upper or lower fastener to pass through. A limiting member 47 is provided on the inner wall of the hole in the plate 46, and the limiting member 47 contacts the outer wall of the upper or lower fastener to restrict its position. Therefore, in actual use, the limiting member 47 restricts the position of the upper or lower fastener, facilitating subsequent adsorption and preventing the upper or lower fastener from moving after detaching from the placement rod 411.

[0061] Since the upper and lower fasteners have four sides, there are at least four limiting members 47. In order to adapt to the shape of the limiting plate 43, one is provided on the side close to the limiting plate 43 and can be located in the groove 431, and two are provided on the side away from the limiting plate 43, so that they can abut against the limiting plate 43 to limit the position of the limiting plate 43. In addition to the limiting member 47, a baffle is also provided on the side close to the limiting plate 43, and the baffle is adapted to the side of the limiting plate 43 to limit the position of the limiting plate 43.

[0062] Furthermore, to ensure that the movement is in place, detectors are adapted to both the push plate 42 and the limit plate 43 to detect whether the movement is in place.

[0063] like Figures 6-9 As shown, other details are as follows: First, each storage area is provided with a base plate 44, and a mounting component 45 is provided on the base plate 44. A slider 451 that can move up and down is provided on the mounting component 45, and a push plate 42 that can move back and forth is provided on the slider 451. The horizontal movement of the push plate 42 is achieved using a cylinder, and the movement of the slider 451 is achieved using a motor and a lead screw. Furthermore, a slide rail is provided on the mounting component 45 corresponding to the slider 451.

[0064] Meanwhile, each storage area is provided with a side plate 48, and the side plate 48 is provided with a slider 481 that can move up and down, and the slider 481 is provided with a limiting plate 43 that can move back and forth. The horizontal movement of the limiting plate 43 is achieved by a cylinder, and the movement of the slider 481 is achieved by a motor and a lead screw. The side plate 48 is also provided with a slide rail corresponding to the slider 481.

[0065] Furthermore, each storage area is equipped with a base plate 44, and a movable chain 49 is mounted on the base plate 44. Movable seats 41 located within the same storage area are all connected to the chain 49, and the movable seats 41 move under the influence of the chain 49. The movement of the chain 49 is achieved by a motor driving a gear to rotate, which in turn moves the chain 49 meshing with the gear. A groove rail 441 is mounted on the base plate 44, and the movable seats 41 are mounted on the groove rail 441 and move along it.

[0066] like Figure 12 As shown, the specific structure of the push rod 51 is as follows: First, there are two push rods 51, which correspond to the upper fastener and the lower fastener respectively. One end of the push rod 51 is connected to the drive source and moves under the drive of the drive source. The other end of the push rod 51 is symmetrically provided with two snap-fit ​​parts 511. The snap-fit ​​parts 511 are provided with snap-fit ​​grooves 512. The two ends of the upper fastener or the lower fastener are respectively located in the snap-fit ​​grooves 512 of the two snap-fit ​​parts 511.

[0067] The drive source is a motor, which drives a pulley and a belt, which in turn moves the push rod 51 connected to the belt. Therefore, in actual use, the snap-fit ​​groove 512 ensures that both ends of the upper or lower fastener are positioned within the snap-fit ​​grooves 512 of the two snap-fit ​​parts 511, thereby limiting the height and ensuring a better snap-fit ​​effect. This is because existing push rods 51 contact one side of a set of fasteners to push them, thus lacking height limitation. This can cause the position of the upper or lower fastener to change or deform during the pushing process, resulting in a poor snap-fit ​​effect. The snap-fit ​​groove avoids this problem.

[0068] Furthermore, brushes 55 are provided on one side of the push rod 51 corresponding to both the upper and lower fasteners. The brushes 55 are used for limiting, that is, restricting the position of the upper or lower fasteners. Moreover, the brushes are soft, so they will not damage the upper or lower fasteners.

[0069] like Figures 9-11 As shown, the specific structure of the adsorption element 53 is as follows: First, the adsorption element 53 is mounted on the rod 56, and the rod 56 is connected to the ends of two connecting rods 57. The other end of each connecting rod 57 is connected to a rotating wheel 58, and the rotating wheels 58 of the two connecting rods 57 rotate synchronously. Therefore, in actual use, the rotation of the rotating wheel 58 drives the end of the connecting rod 57 connected to the rotating wheel 58 to rotate, and the other end of the connecting rod 57 swings, driving the rod 56 to move, thereby moving the adsorption element 53.

[0070] The rotation of the rotating wheel 58 is driven by a motor, and the rotating wheels 58 of the two connecting rods 57 are located within the same belt to achieve synchronous rotation. The motor is connected to the belt. Therefore, the motor first drives the belt to move, and then synchronously drives the rotating wheels 58 of the two connecting rods 57 to rotate. The above describes the basic principle and main features of this utility model, as well as its advantages. However, this utility model is not limited to the above embodiments. Therefore, various changes and modifications can be made to this utility model without departing from its principles and scope, and all such changes and modifications fall within the scope of the claimed utility model.
