Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bag making, particularly to a swing transfer device for packaging bags. BACKGROUND

[0002] Packaging bags are closely related to our life, including non-woven bags, paper bags, plastic bags, etc. Take non-woven bags for example, non-woven bags have the characteristics of environmental protection and practicality, and have been widely promoted and used in recent years, thus promoting the rapid development of non-woven bag making automatic forming technology. However, with the development of non-woven fabrics in China in recent years, three-dimensional bags with strong three-dimensionality have become the mainstream of non-woven bags. The existing non-woven three-dimensional bags are formed by a three-dimensional bag forming machine in one process. In the process, a mold lifting device is needed to press the flat non-woven fabric into a cuboid through the mold.

[0003] In the existing three-dimensional bag forming machine, the space form of the three-dimensional bags needs to be changed sometimes between the two adjacent stations. For example, the existing non-woven three-dimensional bag forming machine mostly folds and flattens the formed three-dimensional bags, and then conveys them to a bag arranging mechanism for bag arranging operation. After the bag arranging is completed, the multiple non-woven bags are flattened and arranged into a pile and then packaged and transported together. However, the existing bag arranging mechanism is generally a vertical bag arranging device. The packaging bags arranged by the vertical bag arranging device are placed vertically, and the packaging device is a horizontal packaging device. After a certain number of non-woven bags are arranged, the packaging bags are placed on the horizontal packaging device for packaging manually by artificial, or the horizontal packaging device is arranged below the bag arranging mechanism, and the predetermined number of non-woven bags are dropped on the horizontal packaging device for processing. However, this processing method has the problems of easy scattering of non-woven bags or unevenness of the packaged non-woven bags. Therefore, the bag making machine in the prior art may have the problems of low transfer efficiency and poor production effect when transferring three-dimensional bags between two adjacent stations. SUMMARY

[0056] There are various three-dimensional bag forming machines on the market today, including non-woven bag forming machines, paper bag forming machines, and plastic bag forming machines. In existing three-dimensional bag forming machines, the transportation of three-dimensional bags between two adjacent workstations sometimes requires changing the spatial form of the three-dimensional bags. For example, during the processing of such machines, a flat sheet of material is pressed into a three-dimensional packaging bag through a mold. In the final step of bag forming, the folded and flattened formed packaging bags need to be sorted and packaged. However, most existing bag sorting devices are vertical bag sorting devices. After sorting, the bags are generally in a vertical state, while the packaging device is packaged on a horizontal packaging table. Moreover, the vertical bag sorting device and the packaging device are generally arranged at intervals. After a certain number of packaging bags are sorted, they cannot be directly transferred to the packaging device for packaging. A common solution is to manually pick up a certain number of packaging bags and then transfer them to the packaging device. This manual operation method has problems with low transfer efficiency and production efficiency.

[0057] In order to solve the above technical problems, the present application provides a swinging transfer device between adjacent workstations, such as a bag sorting device and a packaging device in a three-dimensional bag forming machine. The swinging transfer device can swing back and forth between the two workstations and transfer a certain number of packaging bag groups in the first workstation to the second workstation. It has the advantages of simple structure, stable swinging conveying and high swinging efficiency.

[0058] Next, the specific structure and working principle of the swing transfer device for packaging bags disclosed in this application are described and explained in detail:

[0059] The embodiments of this embodiment disclose a swing transfer device for packaging bags. The swing transfer device is disposed between two adjacent workstations of a packaging bag making machine, wherein the two adjacent workstations include a first workstation located upstream of the swing transfer device and a second workstation located downstream of the swing transfer device. For example, the first workstation may be a bag sorting station, and the second workstation may be a packing station. Common bag sorting stations are generally equipped with a vertical bag sorting device that vertically arranges the packaging bags one by one to form a certain number of packaging bag groups. The packing station is generally equipped with a packing device that packs the packaging bag groups placed horizontally thereon together using, for example, strapping strips.

[0060] For further information, see Figure 1The swing transfer device for packaging bags provided in the present application includes a transfer mechanism 100 and a swing drive mechanism 200, wherein the transfer mechanism 100 is used to clamp or hold the packaging bag. The swing drive mechanism 200 is used to swing and drive the transfer mechanism 100 to transfer the packaging bag. More specifically, the transfer mechanism 100 includes a transfer frame 110 and at least one pair of clamping assemblies 120 adjustably arranged on the transfer frame 110. A clamping platform is provided on the side of the transfer frame 110 facing the first workstation. The transfer frame 110 is provided with movable slots 130 extending along the width of the clamping platform at intervals. The at least one pair of clamping assemblies 120 can be adjustably passed through the movable slots 130 and extended out of the clamping platform, and can be adjusted in the width and thickness directions of the clamping platform. The adjustment of the pair of clamping assemblies 120 along the width direction of the clamping platform is to accommodate packaging bags of different widths, and the adjustment along the thickness direction of the clamping platform is to accommodate packaging bag groups of different thicknesses.

[0061] It should be noted that the transfer mechanism 100 includes but is not limited to the transfer frame 110 and the clamping assembly 120, and can also be set as a manipulator, a clamping claw, an adsorption claw, etc., which can realize clamping or transferring multiple packaging bags from the first station to the second station. The position adjustment of a pair of clamping assemblies 120 can be achieved by a common adjustment structure. For example, the adjustment of the pair of clamping assemblies 120 can be achieved by a motor and a rack-and-pinion mechanism. For example, the gear in the rack-and-pinion mechanism is set at the output end of the motor, and the pair of clamping assemblies 120 are respectively provided with racks adapted to the gears. The motor drives the gears to rotate, and the gears engage to drive the corresponding racks to move, thereby driving the pair of clamping assemblies 120 to move relative to each other to adjust the position. The position of the pair of clamping assemblies 120 can also be adjusted by, for example, setting a telescopic rod on one side of each clamping assembly 120, or a mechanism such as a screw nut. Those skilled in the art can design and adjust according to actual needs, and this embodiment does not specifically limit this.

[0062] A clamping platform is preferably provided on the transfer rack 110 disclosed in this embodiment. When the clamping assembly 120 clamps the packaging bag group on the clamping platform, one side of the packaging bag group close to the clamping platform of the transfer rack 110 can be tightly attached to the clamping platform, thereby being able to stably clamp a certain number of packaging bags on the transfer mechanism 100. Each clamping assembly 120 can move along the corresponding movable groove 130 for position adjustment.

[0063] For example, if the bags to be transferred are 20 cm wide and 10 cm thick, and the number of bags to be transferred at one time is 20, the pair of clamping assemblies 120 can adjust their width to match the width of the bags, then stably clamp the 20 bags on the transfer rack 110 and transfer them from the first station to the second station. If the width of the bags changes, the pair of clamping assemblies 120 can also adjust their width within the movable groove 130 to ensure stable clamping of the bags. For example, if the number of bags to be transferred decreases to 15 and their thickness decreases, the clamping assemblies 120 will adjust to the corresponding clamping thickness and then move along the thickness direction of the clamping platform to stably hold the bags on one side of the clamping platform. In other words, if the width and thickness of the bags change, the pair of clamping assemblies 120 can adjust their width within the movable groove 130 to ensure stable clamping of the bags.

[0064] The swing drive mechanism 200 includes a driving component 210 and a swing transmission component 220 that are transmission-connected. The swing transmission component 220 is rotatably connected to the transfer frame 110. The driving component 210 can drive the swing transmission component 220 to swing and drive the transfer mechanism 100 to swing back and forth between the first station and the second station.

[0065] Furthermore, in one implementation disclosed in this embodiment, the swing transmission component 220 includes a swing assembly and a movable retreat assembly 230. The swing assembly includes at least a swing portion, one end of which is transmission-connected to the drive component 210 and the other end of which is rotatably connected to the transfer rack 110. With this structure, the drive component 210 can also drive the swing portion to swing, which in turn drives the transfer rack 110 to swing. The movable retreat assembly 230 is transmission-connected to the transfer rack 110. For example, in actual production, the movable retreat assembly 230 and the transfer rack 110 may be rotationally connected or fixedly connected, which is not specifically limited in this embodiment. When the drive component 210 drives the transfer mechanism 100 to swing from the first station toward the second station, the movable retreat assembly 230 drives the transfer rack 110 to swing and move in a direction away from the first station, thereby preventing the transfer rack 110 from colliding with or interfering with the frame or other components.

[0066] Specifically, in this embodiment, one end of the swinging part needs to be connected to the output end of the driving component 210. When the output end of the driving component 210 drives the swinging part to swing, the swinging part rotates relative to the driving component 210, thereby driving the transfer rack 110 to swing. Therefore, one end of the swinging part is rotatably connected relative to the driving component 210, but is actually transmission-connected to the output end of the driving component 210, and the other end of the swinging part can be rotatably connected to the transfer rack 110.

[0067] More specifically, those skilled in the art may configure the swing transmission component 220 in this embodiment to various common mechanisms that can achieve swing transmission. For example, the swing transmission component 220 may be configured as a connecting rod swing mechanism, one end of the connecting rod swing mechanism is connected to the output end of the driving component 210 so that the connecting rod swing mechanism rotates relative to the driving component 210, and the other end is rotatably connected to the transfer mechanism 100, and the connecting rod swing mechanism is used to drive the transfer mechanism 100 to swing back and forth between the first station and the second station. The swing transmission component 220 may also be configured as a swing arm, one end of the swing arm is connected to the output end of the driving component 210 so that the swing arm rotates relative to the driving component 210, and the other end is rotatably connected to the transfer mechanism 100, and the swing of the swing arm is used to drive the transfer mechanism 100 to swing back and forth between the first station and the second station. Those skilled in the art may also configure it according to actual needs, and this embodiment does not specifically limit this.

[0068] It should be noted that the structures related to movement in this application can all be common moving guide rails and moving blocks, sliding guide rails and sliding blocks, rollers and rolling grooves and other moving matching structures, as long as they can achieve movement adjustment. In this embodiment, moving guide rails and moving blocks are preferably used.

[0069] With this structural design, the swinging transfer device for packaging bags disclosed in the present application can quickly and easily transfer packaging bags in the first station to the second station by setting a swinging drive mechanism 200 and a transfer mechanism 100, thereby reducing the time and labor costs of manual operation and improving production efficiency. Furthermore, setting a swinging drive mechanism 200 and a transfer mechanism 100 can realize the rapid and accurate transfer of packaging bags, thereby improving transfer and production efficiency.

[0070] Furthermore, the clamping assembly 120 is adjustable through the movable slot 130 and extends out of the clamping platform, allowing for adjustment along both the width and thickness of the clamping platform. The movable slot 130 facilitates adjustment of the clamping assembly 120, accommodating bags of varying sizes and shapes, thereby enhancing the versatility and flexibility of the device. Furthermore, the swinging conveying method can change the plane of the bags. For example, when transferring from the first to the second station, or from the vertical bag sorting device to the packaging platform, the plane of the bags shifts from a vertical plane to a horizontal plane.

[0071] Next, the swing drive mechanism 200 is explained and described in detail:

[0072] Specifically, in this embodiment, see Figure 2 The swinging part includes a connecting rod mechanism arranged at the output end of the driving component 210 and one side of the transfer frame 110, wherein the connecting rod mechanism includes a first driving connecting rod 221, a first swinging connecting rod 222 and a middle linkage connecting rod 223 that are transmission-connected.

[0073] The first driving link 221 is transmission-connected to the output end of the driving component 210, one end of the first swinging link 222 is rotatably set on the frame 300 and is spaced apart from one end of the first driving link 221, the other end of the first swinging link 222 is rotatably connected to the movable retreat component 230 on one side of the transfer frame 110, and an avoidance groove 2221 is also provided in the middle of the first swinging link 222, one end of the middle linkage link 223 is rotatably connected to the other end of the first driving link 221, and the other end is rotatably set in the middle of the first swinging link 222.

[0074] Please note that, see Figure 2 In the present application, an avoidance groove 2221 is further provided in the middle of the first swing link 222. In the process of the middle linkage link 223 rotating and driving the first swing link 222 to swing, the avoidance groove 2221 can avoid interference between the middle linkage link 223 and the first swing link 222 during transmission, so as to ensure that the first swing link 222 in the three-link mechanism can swing back and forth and drive the movable retreat component 230 and the transfer rack 110 to swing back and forth between the first station and the second station and transfer the packaging bags.

[0075] Furthermore, the length of the first swing link 222 is greater than that of the first drive link 221. The drive component 210 drives the first drive link 221 to swing, which in turn drives the middle linkage link 223, and drives the first swing link 222 to swing. The first swing link 222 drives the movable retreat assembly 230 and the transfer rack 110 to swing back and forth between the first and second workstations. Furthermore, the swing angle of the swing transmission component 220 is equal to the angle between the plane of the first workstation and the plane of the second workstation, and the angle range is between 60° and 120°.

[0076] Specifically, the length of the first swing link 222 in the embodiment is greater than the length of the first drive link 221, has a larger swing stroke, and ensures that the first swing link 222 can drive the transfer frame 110 to swing between the first station and the second station. For example, the specific length by which the first swing link 222 is greater than the first drive link 221 can be 10 cm, 15 cm, 20 cm, etc. Those skilled in the art can adjust and design according to requirements, and the embodiment does not make specific limitations thereon. The angle between the plane where the first station is located and the plane where the second station is located can be 60°, 90°, 100°, 120°, etc. For example, in the embodiment, adjacent two stations are a bag arranging station and a packaging station. The packaging bag in the first station is placed in the vertical direction in the bag arranging device, and the packaging bag in the second station needs to be placed horizontally on the packaging platform. Therefore, in the embodiment, the angle range of the angle between the plane where the first station is located and the plane where the second station is located is preferably set to 90°. When the first swing link 222 drives the transfer frame 110 to swing and transfer the packaging bag from the first station to the second station, the packaging bag is transferred from the vertical state to the horizontal state.

[0077] With the structure, the swing part is designed as a link mechanism, which has the advantage of simple structure. In addition, the design as a link mechanism can enable the swing transfer device to move along a predetermined motion trajectory. For example, the swing angle of the swing transmission part 220 can be adjusted to adapt to the planes of the two stations in front and back. In the application, the link mechanism driving transfer mechanism 100 can move back and forth and transfer the packaging bag along the predetermined swing trajectory, thereby efficiently and stably achieving the swing transfer of the packaging bag.

[0078] The embodiment of the utility model discloses a swing transfer device of packaging bag, please see Figure 2 The retreat assembly 230 includes a retreat guide part and a retreat rotating part. The retreat rotating part is arranged on the rack 300 away from one side of the transfer frame 110. The retreat rotating part includes a rotating seat 234 arranged on the rack 300. The rotating seat 234 is provided with a rotating mounting part 233 close to one side of the rack 300. The rotating seat 234 is rotatably arranged on the rack 300 through the rotating mounting part 233. The rotating seat 234 is provided with a guide groove 235 away from one side of the rack 300. The retreat guide part is movably arranged in the guide groove 235.

[0079] The retreat guide part includes a retreat guide rail 232. The rotating seat 234 and the transfer frame 110 are further provided with a guide block 231 fixed to the retreat guide rail 232. The guide block 231 is rotatably connected with the first swing link 222 of the swing part. The guide block 231 and the retreat guide rail 232 are fixedly connected. Specifically, please see Figure 2In this embodiment, a rotating shaft is further provided on one side of the guide block 231. The swinging end of the first swing link 222 in the swing transmission component 220 is rotatably connected to the guide block 231 via the rotating shaft. The guide block 231 may be provided with an adjustment slot within which the rotating shaft can be adjusted. A retreat guide rail 232 extends from the transfer frame 110 toward the rotating seat 234. One end of the retreat guide rail 232 is fixedly mounted on one side of the transfer frame 110, and the other end is movably disposed within the guide slot 235. When the swing assembly drives the retreat guide rail 232 and the transfer frame 110 to swing, the retreat guide rail 232 drives the transfer frame 110 to move away from the first workstation, and the other end of the retreat guide rail 232, away from the transfer frame 110, can rotate relative to the frame 300.

[0080] Specifically, see Figure 1 as well as Figure 2 The side of the retreat rotating component close to the frame 300 is provided with a rotating mounting portion 233, and a rotating shaft is provided in the rotating mounting portion 233, so that the retreat rotating component can rotate relative to the frame 300, and a guide groove 235 is provided on the rotating seat 234. With such a structure, when the moving retreat component 230 drives the transfer rack 110 to move and retreat in the direction away from the first workstation and swing, the retreat guide rail 232 moves backward in the guide groove 235, and the retreat guide rail 232 swings relative to the frame 300 as the rotating seat 234 rotates, thereby causing the transfer rack 110 to swing backward and flip, while moving and retreating in the direction away from the first workstation, avoiding interference between the transfer rack 110 and other structures, and the retreat guide rail 232 gradually swings from a horizontal state to a vertical state.

[0081] Next, the operation process of the swing portion and the movable retreat component 230 is described with examples:

[0082] For example, in the initial state, see Figure 1 The transfer rack 110 faces the first station and is in a vertical position. After the clamping assembly 120 on the transfer rack 110 holds the vertical packaging bag, see Figure 2, the driving component 210 drives the first driving connecting rod 221 to swing around the output end of the driving component 210, then drives the middle linkage connecting rod 223 to swing, the middle linkage connecting rod 223 drives the first swing connecting rod 222 to swing, and drives the holding packaging bag transfer frame 110 to swing towards the direction away from the first station, that is, when the first swing connecting rod 222 swings, the retreat guide rail 232 and the transfer frame 110 swing around the rotating installation part 233 and the rotating seat 234, and at this time, the moving retreat assembly 230 drives the transfer frame 110 to retreat and swing away from the first station, the retreat guide rail 232 moves relative to the guide groove 235 when swinging, and the transfer frame 110 swings while moving backward along the moving retreat assembly 230 to retreat, avoiding interference between the transfer frame 110 and other structures, and finally the transfer frame 110 and the moving retreat assembly 230 swing to be located above the packaging platform, at this time, the retreat guide rail 232 swings from the horizontal state to the vertical state, and then after the packaging bag is placed on the packaging platform by loosening the clamping assembly 120, the transfer frame 110 is swung in the direction and action opposite to the feeding to reset, and is ready for the next transfer swing.

[0083] With the structure, the moving retreat assembly 230 is arranged to make the transfer frame 110 move away from the first station during the swing and transfer of the packaging bag, avoiding interference between the transfer frame 110 and the first station, further arranging the retreat guide part and the retreat rotating part can ensure that the first swing connecting rod 222 drives the retreat guide rail 232 and the transfer frame 110 to move relative to the retreat rotating part during the swing and transfer, the retreat guide rail 232 and the transfer frame 110 move and swing synchronously, and the trajectory and time of each reciprocating swing are predetermined, and the swing and transfer action of the packaging bag group can be repeated, so that the swing and transfer of the packaging bag group has better efficiency.

[0084] Further preferably, the swing assembly and the moving retreat assembly 230 are arranged in two groups, and when viewed from the front of the transfer frame 110 towards the swing driving mechanism 200, the two groups of swing assemblies and moving retreat assemblies 230 are arranged symmetrically and spaced apart on both sides of the transfer frame 110, and each side of the swing assembly and the moving retreat assembly 230 are drivingly connected. Arranging two groups of swing assemblies and moving retreat assemblies 230 makes the mechanism swing and work more stably.

[0085] Next, the driving component 210 of the swing driving mechanism 200 will be described in detail.

[0086] The swing driving mechanism 200 includes a driving unit and a driving assembly, please refer to Figure 1The drive unit includes a drive motor 211, and an output-end synchronous pulley 212 is provided at the output end of the drive motor 211. The drive assembly includes a synchronous belt 213, a transmission rod assembly, and a torque converter 218. The synchronous belt 213 is in transmission connection with the output-end synchronous pulley 212 and the transmission rod assembly. The transmission rod assembly includes a first transmission rod 214 and a second transmission rod 215 spaced apart on both sides of the transfer frame 110. The torque converter 218 is provided at the output end of the transmission rod assembly.

[0087] A first synchronous pulley 216 and a second synchronous pulley 217 are fixedly mounted at the bottom of the first transmission rod 214 and the second transmission rod 215, respectively. The synchronous belt 213 is sequentially wound around the output synchronous pulley 212 and the first and second synchronous pulleys 216 and 217. The input end of the torque converter 218 is in transmission connection with the output end of the transmission rod assembly. The torque converter 218 is provided with a steering transmission assembly, which is in transmission connection with the transmission rod assembly. The output end of the torque converter 218 drives the first drive link 221 to swing back and forth. It should be noted that the first and second synchronous pulleys 216 and 217 are fixedly mounted at the bottom of the first and second transmission rods 214 and 215, so that when the first and second synchronous pulleys 216 and 217 rotate, they can drive the first and second transmission rods 214 and 215 to rotate.

[0088] It should be noted that the "torque converter" in this application is a component that has a steering transmission assembly inside and can increase or decrease the torque transmitted therethrough. That is to say, the "torque converter" in this application can change the torque transmission direction and increase the output torque through the steering transmission assembly inside it. The steering transmission assembly in the torque converter 218 can be a worm gear mechanism, a bevel gear mechanism, etc. For example, when the steering transmission assembly is set as a worm gear mechanism, the worm and the worm wheel in the worm gear mechanism are driven, and the worm is connected to the input end of the torque converter 218, and the worm wheel is connected to the output end of the torque converter 218. The torque of the first transmission rod 214 or the second transmission rod 215 is converted and output into a torque that drives the first drive link 221 to swing, thereby changing the torque output direction, increasing the output torque and reducing the speed of driving the first drive link 221 to swing, thereby driving the first swing link 222 to swing smoothly, and after the torque is increased, it can smoothly drive the transfer mechanism 100 to swing. For another example, when the steering transmission assembly is configured as a bevel gear mechanism, those skilled in the art can adjust the output torque by adjusting the gear ratio of the two bevel gears meshing with each other in the bevel gear mechanism, which will not be described in detail in this embodiment.

[0089] It should be noted that the skilled in the art can also realize the synchronous rotation of the two groups of transmission rods driven by the motor in other ways, for example, a gear mechanism, a worm gear mechanism, a screw rod mechanism, etc. For example, when the gear mechanism is provided, the bottom ends of the first transmission rod 214 and the second transmission rod 215 are fixedly provided with driven gears, the output end of the motor is provided with a driving gear, and a synchronous gear is arranged between the driving gear and the two driven gears. The synchronous gear is engaged with the driving gear and the two driven gears, respectively. When the motor drives the driving gear to rotate, the driving gear drives the synchronous gear to rotate, and the synchronous gear drives the two driven gears to rotate, thereby driving the first transmission rod 214 and the second transmission rod 215 to synchronously rotate through the two driven gears, respectively. The skilled in the art can also adjust and design according to actual needs, and the present embodiment does not make specific limitations.

[0090] By adopting the structure, the driving motor 211, the group of synchronous belts, and the two groups of transmission rod assemblies are connected in a transmission manner, so that the driving motor 211 drives the group of synchronous belts to rotate, the synchronous belts drive the two groups of transmission rods to synchronously rotate, the synchronicity and stability are higher, and then the two transmission rods drive the two torque converters 218 to synchronously rotate, respectively, so that the driving motor 211 and the transmission structure are matched to synchronously drive the two groups of swing assemblies and the moving retreat assembly 230 to move.

[0091] The embodiment of the utility model discloses a swing transfer device of packaging bag, please see Figure 1 And Figure 3 It should be noted that Figure 3 For Figure 1 The specific structure diagram of the back of the transfer frame 110, the transfer frame 110 includes a transfer holding plate, and the clamping assembly 120 further includes a first holding seat 121 and a second holding seat 122, the first holding seat 121 and the second holding seat 122 are arranged on the back of the transfer holding plate, and the first holding seat 121 and the second holding seat 122 are movably adjusted in position relative to the width direction of the transfer holding plate. A plurality of clamping claws 123 are arranged on the first holding seat 121 and the second holding seat 122, and the plurality of clamping claws 123 are movably adjusted in position along the thickness direction of the transfer holding plate.

[0092] The skilled in the art can set 2 groups, 3 groups, 4 groups or even more number of clamping claws 123 according to needs. In one of the implementation manners, three groups of clamping claws 123 are symmetrically arranged on the first holding seat 121 and the second holding seat 122, and each clamping claw 123 is "L" shaped from the part of the transfer holding plate extending out of the back of the transfer frame 110.

[0093] With this structural design, the first holding seat 121 and the second holding seat 122 can be adjusted to be movable relative to the width direction of the transfer holding plate to adjust the spacing and size of the clamping claws 123, thereby adapting to the clamping and holding of packaging bags of different sizes. At least two groups of clamping claws 123 are provided and all are "L"-shaped, which can be more stable during clamping and holding.

[0094] Next, the telescopic drive assembly 140 of the swing transfer device disclosed in this application is described with an example:

[0095] First of all, it should be noted that the telescopic drive assembly 140 is provided to drive the clamping claws 123 to move along the thickness direction of the transfer holding plate, thereby adjusting the holding length of the clamping claws 123 so that the clamping claws 123 can stably hold the packaging bag.

[0096] See Figure 3 A telescopic driving assembly 140 is provided on the side of the transfer holding plate away from the clamping platform. The telescopic driving assembly 140 drives the clamping claw 123 to be movable and adjustable along the thickness direction of the transfer holding plate.

[0097] Specifically, the telescopic drive assembly 140 includes a telescopic drive motor 141, a driving bevel gear 142, a driven bevel gear 143, a transmission cross bar 144, an adjusting gear 145 and a moving rack 146. The axis lines of the driving bevel gear 142 and the driven bevel gear 143 are perpendicular and mesh with each other to transmit power. The driving bevel gear 142 is arranged at the power output end of the telescopic drive motor 141, the driven bevel gear 143 is transmission-connected to the driving bevel gear 142 and fixedly connected to the transmission cross bar 144, the transmission cross bar 144 extends along the width direction of the transfer holding plate, the adjusting gear 145 is arranged in the middle of the transmission cross bar 144, the moving rack 146 is transmission-engaged with the adjusting gear 145, the moving rack 146 is fixedly provided on the clamping claw 123, and the moving rack 146 extends along the length direction of the clamping claw 123. The length direction of the moving rack 146 and the clamping claw 123 is the same as the thickness direction of the transfer holding plate. The telescopic drive motor 141 drives the active bevel gear 142 to rotate, and the active bevel gear 142 drives the driven bevel gear 143 and the transmission cross bar 144 to rotate synchronously. The transmission cross bar 144 drives the adjusting gear 145 to rotate, and the adjusting gear 145 is engaged with the moving rack 146 and drives the moving rack 146 to move back and forth. Finally, the moving rack 146 drives the clamping claw 123 to move along the thickness direction of the transfer holding plate and clamp the packaging bag group along the thickness direction of the packaging bag group.

[0098] It should be noted that those skilled in the art may also configure the driving helical gear 142 and the driven helical gear 143 as a driving bevel gear and a driven bevel gear to transmit steering power, which is not specifically limited in this embodiment.

[0099] With this structural design, the adjusting gear 145 is driven to rotate by the telescopic drive motor 141, and the adjusting gear 145 is linked to move the moving rack 146, so that the clamping claw 123 is moved and adjusted along the thickness direction of the transfer holding plate, thereby realizing the clamping and loosening action of a certain number of packaging bag groups. Specifically, when the moving rack 146 drives the clamping claw 123 to move toward the side of the transfer holding plate, the packaging bag group on the transfer holding plate can be clamped, thereby facilitating the subsequent swing transfer of the device. After the swing drive mechanism 200 drives the transfer mechanism 100 to complete the swing transfer, the moving rack 146 drives the clamping claw 123 to move away from the transfer holding plate, and finally places the packaging bag group on the second workstation.

[0100] The embodiment of the present utility model also discloses a swing transfer device, see Figure 3 A position adjustment component 150 is also provided on the side of the transfer holding plate away from the clamping platform. The position adjustment component 150 drives the first holding seat 121 and the second holding seat 122 to be movable and adjustable along the width direction of the transfer holding plate. It should be noted that the position adjustment component 150 is used to adjust the position of the first holding seat 121 and the second holding seat 122, and then adjust the width between the two sets of clamping claws 123. Specifically, by adjusting the width between the two sets of clamping claws 123, it can adapt to clamping packaging bags of different widths.

[0101] The position adjustment assembly 150 includes an adjustment drive motor 151, a moving timing belt 152, a first moving block 153, and a second moving block 154. For example, a timing pulley is provided at the output end of the adjustment drive motor 151, and a driven timing pulley is provided at the end away from the timing pulley. The moving timing belt 152 wraps around the timing pulley and the driven timing pulley, extending along the width of the moving timing belt 152. The first moving block 153 and the second moving block 154 are fixedly mounted on the moving timing belt 152 and located on either side of the moving timing belt 152. The first moving block 153 and the second moving block 154 are respectively fixedly connected to the first holding base 121 and the second holding base 122. A moving guide rail 155 extending along the width of the transfer holding plate is also provided. Moving guide blocks that mate with the moving guide rail 155 are provided on the first holding base 121 and the second holding base 122.

[0102] For example, when the output end of the drive motor 151 is adjusted and the synchronous pulley rotates, the synchronous pulley drives the moving synchronous belt 152 to move, and the first moving block 153 and the second moving block 154 fixed on both sides of the moving synchronous belt 152 approach or separate from each other, and drive the first holding seat 121 and the second holding seat 122 to move closer to or separate from each other.

[0103] With this structural design, a position adjustment component 150 is provided to adjust the position of the first holding seat 121 and the second holding seat 122 relative to the transfer holding plate, thereby adjusting the position and spacing of the clamping claws 123, and further providing a movable guide rail 155 and a movable guide block to cooperate, so that the first holding seat 121 and the second holding seat 122 are more stable when adjusted or moved.

[0104] The present invention also discloses a swinging transfer device for packaging bags. A first station is provided with a vertical bag sorting device (not shown) located upstream of the swinging transfer device, and a second station is provided with a packaging device (not shown) located downstream of the swinging transfer device. The packaging bags in the vertical bag sorting device fall vertically and are sorted by the vertical bag sorting device. The packaging device is provided with a horizontally arranged packaging platform, on which the packaging bags are placed horizontally. During packaging, the packaging is completed by wrapping the stacked packaging bags with a strapping strip. Furthermore, when the transfer mechanism 100 is located at the first station, the transfer rack 110 is in a vertical position. When the transfer mechanism 100 is located at the second station, the transfer rack 110 is in a horizontal position.

[0105] In summary, the utility model discloses a swing transfer device for packaging bags, which can conveniently and quickly transfer the packaging bag group in the first station to the second station, and at the same time change the posture of the packaging bag group during the transfer process, and transfer the packaging bag from a vertical state to a horizontal state, thereby reducing the time and labor costs of manual operation and improving production efficiency. The swing drive mechanism 200 has a certain motion trajectory, which can effectively reduce the shaking of the packaging bag group due to inertia and prevent the packaging bag from falling off or being damaged. The clamping assembly 120 is arranged to be movably adjustable along the width direction and thickness direction of the clamping platform, which can adapt to packaging bags of different sizes and shapes, thereby improving the versatility and flexibility of the equipment.

[0106] Furthermore, setting up a movable retreat component 230 can enable the transfer rack 110 to move and retreat in the direction away from the first workstation during the process of swinging and transferring the packaging bags, thereby avoiding interference between the transfer rack 110 and the bag sorting device, and the clamping component 120 is set to an adjustable claw structure, which has the advantages of simple and convenient adjustment and stable clamping.

[0107] Finally, a brief description is given of the bag holding and transfer process of the swing transfer device for packaging bags disclosed in this application:

[0108] In the initial state, the transfer rack 110 in the transfer mechanism 100 faces the first upstream station. Figure 1 At this time, the transfer rack 110 is in a vertical direction and the retreat guide rail 232 is in a horizontal direction. Multiple clamping claws 123 extend between the transfer holding plate and the first workstation. The sorted packaging bags are sequentially positioned between the clamping claws 123 and the transfer rack 110 along the vertical direction. When a predetermined number of packaging bags, such as 20 packaging bags, need to be transferred, the position adjustment assembly 150 starts to operate. See Figure 1 and Figure 3 The position adjustment component 150 adjusts the spacing of the clamping claws 123 in the width direction of the packaging bag. For example, the driving motor 151 is adjusted to drive the moving synchronous belt 152 to rotate, so that the first moving block 153 and the second moving block 154 fixed on both sides of the moving synchronous belt 152 are close to each other, and drive the first holding seat 121 and the second holding seat 122 to move closer to each other, thereby making the pair of clamping claws 123 on the first holding seat 121 and the second holding seat 122 move along the width direction of the packaging bag and clamp the packaging bag, and the telescopic driving component 140 will also move and drive the clamping claws 123 to move along the width direction of the packaging bag. The claws 123 move and adjust their positions along the thickness direction of the packaging bag, so that the clamping claws 123 move along the thickness direction of the packaging bag group and clamp and hold the packaging bag group. Specifically, the telescopic drive motor 141 drives the active bevel gear 142 and the driven bevel gear 143 to engage and transmit, and the driven bevel gear 143 and the transmission cross bar 144 rotate synchronously. The transmission cross bar 144 drives the adjusting gear 145 to rotate, and the adjusting gear 145 engages with the moving rack 146 and drives the moving rack 146 to move. The moving rack 146 drives the clamping claws 123 to hold the packaging bag group along the thickness direction of the packaging bag.

[0109] When the clamping claws 123 clamp the packaging bag tightly on one side of the transfer rack 110, the swing drive mechanism 200 starts to work. Figure 1 The driving motor 211 drives the output end synchronous pulley 212 to rotate, the output end synchronous pulley 212 drives the synchronous belt 213 to rotate, and the synchronous belt 213 simultaneously drives the first synchronous pulley 216 and the second synchronous pulley 217 to rotate, thereby driving the first transmission rod 214 and the second transmission rod 215 to rotate, the first transmission rod 214 and the second transmission rod 215 respectively drive the two torque converters 218 to move synchronously, and the two torque converters 218 synchronously drive the first driving connecting rod 221 on each side to swing.

[0110] Further, see Figure 2When the torque converter 218 drives the first driving link 221 to swing, the first driving link 221 drives the middle linkage link 223 to swing, and when the middle linkage link 223 swings, it drives the first swing link 222 to swing. The rotating end of the first swing link 222 and the guide block 231 fixedly arranged on the retreat guide rail 232 are rotatably connected, so the first swing link 222 can drive the retreat guide rail 232 and the transfer rack 110 to swing around the rotating mounting portion 233 and the rotating seat 234. The retreat guide rail 232 will move relative to the guide groove 235 when swinging, avoiding interference between the transfer rack 110 and other structures. Finally, the retreat guide rail 232 drives the transfer rack 110 and the packaging bag group clamped by the clamping assembly 120 to swing from the first station to the second station. The retreat guide rail 232 swings from the horizontal state to the vertical state, and the transfer rack 110 accordingly flips 90 degrees from the vertical state to the horizontal state. At this time, the transfer rack 110 is located above the second workstation.

[0111] When the transfer rack 110 is swung to the second station, for example, above the packaging platform, the transfer rack 110 holds the side of the packaging bag group toward the plane where the packaging platform is located, and then the clamping component 120 is actuated to loosen the packaging bag and place the packaging bag group on the packaging platform. The action of the clamping component 120 to loosen the packaging bag group is exactly opposite to the action of clamping the packaging bag. After the packaging bag group is placed on the packaging platform, the swing drive mechanism 200 swings in the direction and action opposite to that of the feeding, so that the transfer rack 110 is reset and swings from the second station to the first station, preparing for the next transfer swing. It should be noted that the swing direction and action process of the transfer rack 110 when swinging from the second station to the first station are opposite to the process of swinging the packaging bag, so this embodiment will not be repeated.
