Description

Technical Field

[0001] This invention relates to a clamp locking pin system and a method for locking the pin, and particularly to an automatic clamp locking pin system and a method for locking the pin on barrel hoops in a barrel bottling production line, belonging to the field of barrel bottling. Background Technology

[0002] In product manufacturing, toxic products such as cyanide and arsenic are generally produced in unmanned workshops on actual production lines. However, in packaging production lines, manual weighing and manual packaging are still required. Although corresponding protective measures are taken during production, it is still difficult to avoid chronic poisoning of employees. Over time, this can cause varying degrees of harm to the health of employees. To avoid poisoning incidents, most countries in the world have stopped the production of toxic products that are manually packaged. In order to ensure the smooth operation of production lines, automated unmanned production lines are now used for product packaging.

[0003] There are two types of packaging for toxic products: one is using ton boxes (packing boxes that can hold one ton of weight), and the other is using drum packaging. In the drum packaging production line, empty drums are transported by conveyor lines. In the production line, plastic packaging bags are first placed in the drums, and then a specified weight of toxic product is added to the plastic packaging bags. In order to prevent leakage of toxic products, the mouth of the plastic packaging bags needs to be heat-sealed using a sealing machine. Then, a cap is added above the copper buckle, and the cap and the mouth of the drum are locked with a capping elastic drum clamp with a locking handle. Figure 8 This is a schematic diagram of the planar structure of the barrel hoop. This barrel hoop 47 is used for the upper opening of the packaging barrel. The barrel hoop 47 is equipped with a rotatable locking handle 48. The locking handle 48 is hinged to the barrel hoop 47 via hinge shaft 16a, hinge shaft 2 16b, hinge shaft 3 16c and a connecting rod. The inner circumference of the barrel hoop 48 and the locking handle 48 is provided with grooves. The top cover 14 and the upper periphery of the packaging barrel 13 are locked in the groove of the barrel hoop 47. After the locking handle 48 is locked, the inner circumferential groove of the locking handle 48 overlaps with the outer periphery of the barrel hoop 47. The barrel hoop 47 and the upper locking handle 48 are respectively provided with corresponding barrel hoop insertion holes 15b and handle pin holes 15a. A locking pin needs to be inserted to ensure that it cannot be easily opened.

[0004] Because barrel hoops are manufactured using a roll forming method, and due to variations in the batches of processed materials, the tension of the semi-finished products after roll forming differs. After installing the locking handle, when the barrel hoops are not locked, the different tensions result in different opening sizes, leading to variations in the diameters of multiple barrel hoops and different positions of the locking handle 48. Furthermore, since barrel hoops are composed of multiple parts with varying perimeter thicknesses, localized deformation can occur during handling, resulting in shape differences between barrel hoops. These differences in shape affect the locking process of the packaging barrels. Production line malfunctions such as alarms and jams may occur. Previously, barrel hoop locking was generally done manually, where the precision requirements for the hoops were not high, so product problems were not a concern. However, in automated production lines, the requirements for variability are greater. Furthermore, in automated, unmanned packaging production, various problems can arise. Human intervention carries the risk of coming into close contact with the product. Additionally, because the product is toxic, during handling and transportation, to prevent vibration, snagging, or human error from opening the locking handle 48, and even contact with or ingestion by humans or animals, which could cause poisoning, a safety lock needs to be added to the barrel hoop. Figure 9 This is a schematic diagram of the barrel hoop locking pin structure. The locking pin 17 includes a pin head 18a and a pin tail 18b. A pair of upper pin wings 19b and lower pin wings 19b are set on both sides as double insurance. After insertion, it is difficult to pull out without special tools, thus improving the security factor of the packaging barrel locking handle and preventing it from being easily opened. However, since the packaging process of hazardous products currently requires automated and unmanned operation, the difficulty of inserting the locking pin in an unmanned and automated manner has increased. How to deal with the locking of such differentiated barrel hoops and the insertion of locking pins in an unmanned and automated manner is a problem faced by automated production lines. Summary of the Invention

[0005] In response to the problems of jamming and alarms that may occur during the locking process of barrel hoops in product packaging production lines due to the differences in barrel hoops, this invention provides an automatic barrel hoop locking pin system and locking pin method for barrel production lines. Its purpose is to reduce malfunctions during the locking process of barrels containing toxic products, prevent jamming and alarms during production, reduce the risk of contact with products caused by production line malfunctions, ensure the smooth operation of the production line, prevent accidental opening of barrel hoops that could lead to poisoning risks to humans and animals, and improve packaging safety.

A horizontal rotating arm is connected to the rotating shaft, and a vertical lifting pressing plate is provided at the end of the horizontal arm. The rotation of the rotating shaft is driven by a horizontally inclined cylinder at a certain angle to the side of the conveyor line. Before rotation, the lifting pressing plate is located at the edge position above the conveyor line. When pressing the top cover, the horizontal rotating arm and the lifting pressing plate below rotate to press the top cover above the packaging barrel with the top cover. Furthermore, the packaging barrel clamping device includes a clamping drive device, which includes a base located below the transmission belt. An angle rotation motor is positioned at the center below the transmission belt, and a zigzag multi-section connecting rod is connected to the rotating shaft of the angle rotation motor. The outer ends of the zigzag multi-section connecting rod are connected to the lower parts of a pair of brackets on both sides. The lower ends of the pair of brackets are slidably mounted on horizontal slide rails perpendicular to the conveyor line direction. The forward and reverse rotation of the angle rotation motor drives the brackets on both sides to move in opposite directions along the vertical direction of the conveyor line. The brackets on both sides of the conveyor line include an upper bracket and a lower bracket. A lifting slide rail and a slider are provided between the upper bracket and the lower bracket. A support plate lifting device is fixed on the lower bracket. A pair of barrel hoop support plates are fixed on the top of the support plate lifting device. The arc-shaped barrel body clamp and the arc-shaped barrel top clamp are two pairs of arc clamps respectively set opposite to each other in the middle position and the top position of the pair of brackets. The two pairs of arc clamps are a pair of arc-shaped barrel body clamps and a pair of arc-shaped barrel top clamps. The inner circumference of the two pairs of arc clamps is an arc structure, and the radius of the arc structure is the same as the outer circumference radius of the packaging barrel. Furthermore, the barrel clamping mechanism of the barrel clamping device includes multiple barrel clamping cylinders, which are mounted on the upper surface of a pair of barrel clamping support plates. The cylinder rod ends of the multiple barrel clamping cylinders are arc-shaped, and the arc-shaped structures of the multiple barrel clamping cylinders are concentric with the packaging barrel. The starting position of the arc-shaped structures of the multiple barrel clamping cylinders is located on the outer periphery of the barrel clamp. The barrel hoop locking device's barrel hoop rotation mechanism is mounted on a barrel hoop support plate on one side. The barrel hoop rotation mechanism includes an active rotation mechanism and a driven rotation mechanism. A pair of arc-shaped sliding guide holes are provided on the barrel hoop support plate on one side. These two arc-shaped sliding guide holes are the active arc-shaped sliding guide hole and the driven arc-shaped sliding guide hole, respectively. One end of each arc-shaped sliding guide hole is closer to the barrel hoop, and the other end is farther away. The active rotation mechanism includes an active sliding shaft slidably mounted in the active arc-shaped sliding guide hole. A first magnet mounting plate is mounted on the active sliding shaft, and one or more magnetic blocks are mounted on the first magnet mounting plate facing the packaging barrel. The active rotation mechanism is connected to a rotary cylinder. The mechanisms are interconnected by arc-shaped connecting rods. The driven rotating mechanism is equipped with a driven sliding shaft, which is slidably mounted in the driven arc-shaped sliding guide hole. A second magnet mounting plate is fixed on the driven sliding shaft, and a second magnet is mounted on the second magnet mounting plate. A spring blocking post is mounted on the opposite side of the magnet on the second magnet mounting plate. A spring post is mounted between the spring blocking post and the back of the second magnet mounting plate, and a tension spring is mounted on the spring post. The tension spring is supported at both ends between the spring blocking post and the back of the second magnet mounting plate. A spring clamping post is mounted inside the starting position of the driven arc-shaped sliding guide hole. The starting positions of the driving rotating mechanism and the driven rotating mechanism are located at the end farther from the barrel hoop, and the other end is close to the outer periphery of the barrel hoop. The barrel hoop locking device has a barrel hoop positioning mechanism on the other side of the barrel hoop support plate. The barrel hoop positioning mechanism includes a barrel hoop positioning block, which is located in the rotation direction of the barrel hoop end. The barrel hoop positioning block has a positioning groove, which is opposite to one end of the barrel hoop. After rotation, the barrel hoop rotates into the positioning groove. Furthermore, the barrel hoop locking mechanism and the barrel hoop positioning mechanism of the barrel hoop locking device are set on the barrel hoop support plate on the other side. The barrel hoop locking mechanism includes a locking guide hole opened on the barrel hoop support plate, a locking guide post slidably arranged in the locking guide hole, a barrel hoop locking roller arranged on the locking guide post, and a locking cylinder connected to the locking guide post. The locking cylinder drives the locking guide post to move along the locking guide hole. Furthermore, the three-dimensional lead screw module is mounted on the frame. At the bottom of the three-dimensional lead screw module, there is a Y-direction lead screw module perpendicular to the conveyor line. The Y-direction lead screw module is equipped with a slide rail accessory parallel to the lead screw module. On the Y-direction lead screw module and the slide rail accessory, there is an X-direction lead screw module parallel to the transmission belt. On the X-direction lead screw module, there is a vertical Z-direction lead screw module. The lead screw module is equipped with a rotating device with a small-stroke lifting and clamping cylinder facing the direction of the conveyor line. Furthermore, the rotating device with a small-stroke lifting clamping cylinder includes a rotating servo motor, which is connected to the rotating device shaft through a transmission module. The small-stroke lifting clamping cylinder includes a small-stroke lifting device, with a pair of clamps and a locking pin pressing component below it. Furthermore, the illumination of the pin hole recognition device is located around the camera, and the illumination light is a monochromatic light that is different from the surrounding light. The information exchange steps between the computer of the handle pin hole recognition device and the production line controller are as follows: 1) When the packaging barrel detection sensor installed on the pin station of the barrel hoop detects the packaging barrel, the conveyor line stops rotating. The limiter installed on the pin station of the barrel hoop restricts the movement of the packaging barrel, stops the packaging barrel from moving forward and positions it. 2) The camera of the pin hole recognition device identifies the position of the handle pin hole, obtains the position of the handle pin hole, and calculates the deviation between the actual position and the set position; 3) The computer transmits the deviation value of the handle pin hole position to the controller; 4) The controller issues instructions based on the values ​​transmitted by the computer to correct the X, Y, and Z direction deviations and rotation angle deviations between the parameters of the three-dimensional lead screw module and the rotating device with the small-stroke lifting clamping cylinder and the set position of the handle pin hole. 5) The three-dimensional lead screw module and the rotating device with a small-stroke lifting clamping cylinder move and descend according to the corrected parameters, clamp the locking pin of the vibrating hopper outlet, and then move to the top of the handle pin hole to pre-insert the locking pin into the handle pin hole of the barrel hoop. 6) The locking pin identification system checks the position difference between the locking pin and the handle pin hole again. If there is an error, the small-stroke lifting clamping cylinder removes the erroneous locking pin; the above actions 2)-5) are performed again. After three failures, the buzzer alarms; if there is no error, the small-stroke lifting clamping cylinder rotates 180° under the drive of the rotating device, and the locking pin pressing part on its back presses down the locking pin tail. 7) Complete the information exchange between the computer and the production line controller.

[0007] A method for automatic locking and pin insertion of barrel hoops in a barrel bottling production line, utilizing the aforementioned automatic locking and pin insertion production system for barrel hoops in a barrel bottling production line, the operation flow of which is as follows: 1) Packaging barrels with top lids are conveyed to the barrel clamping station on the conveyor line; 2) After entering the barrel hoop locking station, it is detected by the packaging barrel detection sensor, which feeds the information back to the controller; 3) After receiving the controller command, the limit switch of the packaging barrel on the conveyor line stops the conveyor line at the barrel hoop locking station and the limit switch blocks the forward movement of the packaging barrel. 4) The packaging barrel clamping device is equipped with a pair of arc-shaped barrel body clamps and a pair of arc-shaped barrel top clamps to clamp the packaging barrel; 5) The barrel hoop transfer device moves the barrel hoop from the barrel hoop setting station to a pair of barrel hoop support plates at the barrel hoop locking station. The barrel hoop clamping mechanism clamps the barrel hoop around its perimeter. After the barrel hoop transfer device rises, it returns to the starting position. 6) Rotate the top cover clamping device to the top of the packaging tube and press down the top cover; 7) The barrel hoop rotating mechanism drives the barrel hoop to rotate. 8) The barrel hoop is positioned by the positioning mechanism; 9) The barrel hoop clamping mechanism clamps the barrel hoop again, and the barrel hoop rotating mechanism returns to the starting position; 10) The barrel hoop locking mechanism completes the locking of the barrel hoop, and the top cover pressing device rises and rotates back to the starting position near the support leg; 11) The barrel clamping mechanism, barrel locking mechanism, barrel body clamp and barrel top clamp on the packaging barrel support move away from the packaging barrel and return to the starting position. The limit switch releases and the conveyor rollers start to rotate. 12) The packaging drums flow along the conveyor line toward the drum hoop pinning station; 13) When the packaging barrel detection sensor set on the barrel hoop pin station detects the packaging barrel, the conveyor line stops rotating, the lifting limiter set on the barrel hoop pin station restricts the movement and stops the packaging barrel from moving forward, and a pair of arc-shaped barrel clamps clamp the packaging barrel. 14) The camera of the pin hole recognition device identifies the position of the handle pin hole. 15) The computer transmits the deviation value of the handle pin hole position to the controller; 16) The controller issues instructions based on the values ​​transmitted by the computer to control the three-dimensional lead screw module and the rotating device with a small-stroke lifting clamping cylinder for correction. 17) The three-dimensional lead screw module and the rotating device with a small-stroke lifting clamping cylinder descend according to the corrected parameters, clamp the locking pin of the vibrating hopper outlet, move to the top of the barrel hoop handle pin hole and descend to insert into the handle pin hole. 18) The camera of the pin hole recognition device identifies the position of the handle pin hole and confirms the insertion position; 19) If the position is incorrect, the stroke lifting clamping cylinder removes the locking pin and repeats the above steps 14)-18). After three failures, the buzzer will sound an alarm. 20) When the insertion position is correct, the small-stroke lifting clamping cylinder rotates 180° under the drive of the rotating device, and the locking pin pressing part on its back presses down the locking pin tail. 21) Complete the insertion of the locking pin.

[0008] The positive effects of this invention are as follows: By installing packaging barrel detection sensors between the conveyor rollers at the barrel clamping station on the production line, when a packaging barrel is detected to be in position, a limiter installed between the rollers blocks the packaging barrel and stops the rotation of the conveyor rollers, preventing the packaging barrels from flowing backward on the production line and avoiding collisions and accumulation between packaging barrels; the limiter blocks the flow of packaging barrels, thus achieving positioning; by installing a barrel clamping device between the barrel clamping station and the barrel clamping station, the barrel clamps can be clamped and transported to a pair of barrel clamping support plates during the barrel stopping process, thus locking the barrel clamps; by installing horizontal slide rails perpendicular to the conveyor direction at the bottom of the supports on both sides of the conveyor line, an angle-rotating electric motor installed in the base below the conveyor line can be used to... The machine rotates around a central shaft, causing the two side supports to move synchronously along the vertical direction of the conveyor line. When approaching the packaging drums inside the conveyor line, the drum clamping device in the middle of the support clamps the drums, ensuring stable placement and preventing displacement or shaking of the drum hoops during the locking process. Simultaneously, a pair of drum top clamps on opposite sides of the conveyor line at the top of the support clamps synchronously clamp the upper edge of the packaging drums. The drum hoop support plate on the upper surface of the drum top clamps can receive the drum hoops transported by the drum hoop transfer device. A lifting device on the pair of supports can accommodate packaging drums of different heights, meeting the needs of multi-variety production. A top cover clamping device on the support leg of the drum hoop transfer device rotates to the top cover of the packaging drum. The upward and downward pressure mechanism stabilizes the top cover during the locking process, preventing displacement and improper or offset locking caused by cover shifting. It also facilitates return to the starting position of the arc-shaped sliding guide hole. By rotating the top cover clamping device onto the support leg of the barrel hoop transfer device, it can be moved to the outside of the conveyor center, preventing interference with the normal handling of the barrel hoops. A pair of barrel hoop support plates (i.e., arc-shaped barrel top clamps) are installed at the top of the upper support. These clamps secure the upper edge of the packaging barrel, receiving and supporting the barrel hoops transferred by the transfer device. Under this clamping and supporting condition, the rotation cylinder of the barrel hoop rotation positioning mechanism drives the active rotation mechanism to rotate along the arc-shaped sliding guide hole, causing the active rotation mechanism to drive the driven rotation mechanism to approach the barrel hoop from a distance. The barrel hoop is rotated synchronously by using a magnet to hold it in place. During the rotation, the end of the barrel hoop enters the positioning groove of the barrel hoop positioning block, positioning the barrel hoop in the positioning groove. The locking guide post of the barrel hoop locking mechanism pushes the locking handle to rotate in the opposite direction of the barrel hoop rotation along the locking guide hole, pressing the locking handle close to the outer circumference of the barrel hoop to lock it. After locking, the barrel hoop locking mechanism returns to the starting position, the lifting pressure plate set below the horizontal arm of the top cover pressing device rises and rotates back to the starting position, and the fixing clamp of the clamping device and a pair of barrel hoop support plates move to the sides away from the packaging barrel under the drive of the angle rotation motor. The locking limiter releases, the conveyor line starts to rotate, and the packaging barrel flows to the next station, locking the locking handle on the outer circumference of the barrel hoop to prevent the barrel hoop from opening.By installing a pin hole identification device at the pin-pinning station on the barrel hoop, the position coordinates of the handle pin hole can be determined and fed back to the production line controller. The controller can then adjust the position of the three-dimensional lead screw module based on the coordinates. A rotating device with a small-stroke lifting clamping cylinder can rotate the locking pin angle to align it with the handle pin hole. Another function of the rotating device is that after the locking pin is inserted, it rotates 180° to rotate the locking pin pressing component above the pin tail, causing it to descend within a small stroke, fully inserting the locking pin into the handle pin hole. By setting the small-stroke lifting clamping cylinder, lifting, clamping, and pressing actions of the locking pin can be achieved. This invention reduces malfunctions during the barrel locking process, prevents jamming and alarms during production, reduces the risk of product contact caused by production line malfunctions, ensures smooth production line operation, and prevents accidental opening of the barrel hoop, thus preventing the risk of poisoning to humans and animals.

Detailed Implementation

[0019] The specific technical solution of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, the two barrel top clamps (i.e., barrel top clamp one 35a and barrel top clamp two 35b) and the two barrel hoop support plates (barrel hoop support plate one 50a and barrel hoop support plate two 50b) are the same component. Different names and different designations are used depending on the application location and function. The two barrel top clamps utilize the inner circumference of their arcs, and the two barrel hoop support plates utilize their upper surfaces. Moreover, barrel hoop rotation mechanism, barrel hoop clamping mechanism, barrel hoop positioning mechanism, barrel hoop clamping mechanism, and barrel hoop locking mechanism are respectively provided on the two barrel hoop support plates. The handle pin hole 15a described below is basically the superposition and combination of handle pin hole 15a and barrel hoop pin hole 15b. Since the upper surface of handle pin hole 15a is seen in particular, the combination hole of the two is called handle pin hole 15a.

[0020] The technical solution of this invention is: a barrel hoop locking and locking pin insertion production system for a toxic product barrel bottling production line. Figure 1This diagram illustrates the equipment surrounding the barrel clamping station in a toxic product barrel packaging production line. The barrel clamping and locking pin insertion system includes a packaging barrel 13 conveyed on conveyor line 10, a top cover 14 placed on top of the packaging barrel 13, and a locking pin 17. Along the conveyor line 10, in the direction the packaging barrels are conveyed, a barrel clamping station and a barrel clamp locking pin station are successively installed. Each barrel clamping station and barrel clamp locking pin station is equipped with a packaging barrel detection sensor 11, a limiter 12 for the packaging barrel 13, and a pair of arc-shaped barrel clamps 32a and 32b. At the barrel clamping station, the pair of arc-shaped barrel clamps 32a and 32b... The barrel clamping station is located in the middle of the supports facing both sides of the conveyor line 10. Around the barrel clamping station, there is a barrel clamping device 40 that moves barrel clamps across one side of the conveyor line, a top cover clamping device 60 that rotates back and forth above the barrel clamping station to press the top cover, and a pair of supports slidably positioned on both sides of the barrel clamping station. On the barrel clamping station, on opposite sides of the pair of supports, there are packaging barrel clamping devices and barrel clamping devices. In addition to a pair of arc-shaped barrel clamps 32a and 32b extending into the inside of the conveyor line, the packaging barrel clamping devices also include a pair of arc-shaped barrel top clamps 35a and 35b extending above the conveyor line. Arc-shaped barrel top clamps 35a and 35b are respectively mounted on the top of a pair of supports 33. The upper surfaces of barrel top clamps 35a and 35b are a pair of barrel hoop support plates, namely barrel hoop support plate 50a and barrel hoop support plate 50b. Barrel top clamp 35a and barrel hoop support plate 50a are the same object, and barrel top clamp 35b and barrel hoop support plate 50b are the same object, but with different perspectives and functions. Barrel hoop locking devices are provided on barrel top clamp 35b, barrel hoop support plate 50a, and barrel hoop support plate 50b. The barrel hoop locking devices include a rotation positioning mechanism, a barrel hoop clamping mechanism, and a barrel hoop locking mechanism. The barrel hoop rotation and positioning mechanism includes a barrel hoop rotation mechanism and a barrel hoop positioning mechanism. After the barrel hoop locking device locks the barrel hoop, a barrel hoop upper pin station is set on the side of the locking handle 48 near the conveyor line 10. A locking pin insertion device is set next to the conveyor line 10 on the side of the locking handle 48 on the packaging barrel 13 at the barrel hoop upper pin station. The locking pin insertion device is arranged from top to bottom as follows: a pin hole recognition device 80, a camera 81 and its lighting lamp 82, a three-dimensional lead screw module 70 including X, Y, and Z directions, a locking pin vibrating hopper 90, and the main unit of the pin hole recognition device 80 connected to the camera 81 and its lighting lamp 82. The main unit of the pin hole recognition device 80 is a computer. The Z-direction screw module of the three-dimensional screw module 70 is located on the side closer to the conveyor line. A rotating device 76 with a small-stroke lifting clamping cylinder 77 is installed on the Z-direction screw module facing the conveyor line. The structure between the small-stroke lifting clamping cylinder chuck 78 and the lower locking pin vibrating hopper outlet is structurally compatible, facilitating the clamping of the locking pin 17 after the small-stroke lifting clamping cylinder chuck 78 descends. Information is exchanged between the computer of the pin hole identification device 80 and the production line controller. The barrel hoop transplanting device 40 is supported on the support leg 40a, and a transplanting crossbeam 43 is supported on the support leg 40a.

The illumination lamp 82 emits monochromatic light that is different from the surrounding light. In this embodiment, a red LED light is used. The information exchange steps between the computer of the pin hole identification device 80 and the production line controller are as follows: 1) When the packaging barrel detection sensor 11 set on the barrel clamp pin station detects the packaging barrel 13, the barrel clamp pin conveyor 10 stops rotating, and the limiter 12 set on the barrel clamp pin station blocks the packaging barrel from moving forward, stops the packaging barrel 13 and positions it. 2) The camera 81 of the pin hole recognition device 80 recognizes the position of the handle pin hole, obtains the position of the handle pin hole, and calculates the deviation between the actual position and the set position. 3) The computer transmits the deviation value of the handle pin hole position to the controller; 4) The controller issues instructions based on the values ​​transmitted by the computer to correct the X, Y, Z direction deviations and rotation angle deviations between the action coordinates of the three-dimensional lead screw module 70 and the rotating device 76 with the small stroke lifting clamping cylinder 77 and the set position of the handle pin hole. 5) The three-dimensional lead screw module 70 and the rotating device 76 with the small stroke lifting clamping cylinder 77 move and descend according to the modified parameters, clamp the locking pin 17 at the outlet of the vibrating hopper 90, and then move above the handle pin hole 15a, pre-inserting the locking pin 17 into the handle pin hole 15a of the barrel hoop and the locking handle 48. 6) The locking pin identification system confirms the pre-insertion position of the locking pin again. If the pre-insertion position is incorrect, the small-stroke lifting clamping cylinder removes the incorrect locking pin; 2)-5) are performed again. An alarm is triggered after three failures; if the pre-insertion position is correct, the small-stroke lifting clamping cylinder rotates 180° under the drive of the rotating device, and the locking pin pressing part 79 on its back presses down the tail of the locking pin. 7) Complete the locking pin insertion identification; The vibrating hopper 90 has an internal spiral track inside the vibrating hopper body 91, a vibrator at the bottom of the vibrating hopper body 91, and an external spiral track 93 (i.e., a spiral R-axis) outside the vibrating hopper body 91.

[0033] In this embodiment, the lock pin recognition system uses a recognition system produced by Shenzhen Hikvision Co., Ltd., which is existing technology.

[0034] A method for automatic locking and pin insertion of barrel hoops in a barrel bottling production line, utilizing the aforementioned automatic locking and pin insertion system for barrel hoops in a barrel bottling production line, wherein the automatic locking and pin insertion method for barrel hoops in the barrel bottling production line is as follows: The sequence of operations for the packaging drum clamp locking device is as follows: 1) A packaging barrel 13 with a top cover 14 is conveyed to the barrel clamping station on the conveyor line 10; 2) After entering the barrel hoop locking station, it is detected by the packaging barrel detection sensor 11, and the information is fed back to the controller; 3) After receiving the controller command, the limiter 12 of the packaging barrel 13 on the conveyor line 10 stops rotating and the limiter 12 blocks the forward movement of the packaging barrel 13. 4) The controller controls the rotation of the angle rotation motor 23 to rotate the shaft of the "Z"-shaped multi-section connecting rod 26 to move, and the lower support moves along the horizontal slide rail 24 to the middle of the conveyor line 10. The barrel top clamp 1 35a, barrel top clamp 2 35b and barrel hoop support plate 1 50a and barrel hoop support plate 2 50b clamp the packaging barrel 13. 5) The barrel hoop transplanting device 40 moves from the middle position of the transplanting beam 43 to a position above the barrel hoop setting worker's position. After the transplanting lifting mechanism 42 descends, multiple barrel hoop transplanting magnets 45 pick up one barrel hoop 47. After picking up the barrel hoop 47, it rises and moves to a position above the barrel hoop locking station. The clamping mechanism clamps the barrel hoop 47. When the transplanting lifting mechanism 42 rises, it makes the magnets clamp the barrel hoop 47. Separate, the barrel hoop transplanting device 40 returns to the starting position, and the multiple barrel hoop clamping cylinders 51 retract to the starting position; 6) The top cover pressing device 60 rotates to the position above the packaging barrel 13 where the barrel hoop 47 is located under the drive of the horizontally inclined cylinder 63, and presses down the top cover 14; 7) The indexing cylinder 56 of the barrel hoop rotation mechanism drives the active rotation mechanism 58 and the driven rotation mechanism 59 to rotate along the active arc sliding guide hole 55a and the driven arc sliding guide hole 55b respectively, and approach and use the magnets therein to attract the barrel hoop 47 to rotate. 8) After the barrel hoop 47 rotates, the end 49 of the barrel hoop enters the positioning groove 53a of the barrel hoop positioning block 53, and the positioning detection sensor detects that the barrel hoop is in position; 9) The multiple clamping cylinders 51 of the clamping mechanism extend their cylinder rods again to clamp the periphery of the clamping hoop 47, and the clamping mechanism returns to its starting position. 10) Driven by the barrel clamping cylinder 52a, the clamping guide post 52b moves along the clamping guide hole 54. The clamping roller 52 on the clamping guide post 52b pushes the clamping handle 48 to the outer periphery of the barrel clamp 47, locking the barrel cover 13 onto the upper edge of the packaging barrel 13, completing the clamping of the barrel clamp 47. The top cover pressing device 60 rises and rotates back to the starting position near the support leg 48. 11) The barrel clamping mechanism, barrel locking mechanism, and packaging barrel clamping device return to the starting position. The limiter 12 of the packaging barrel at the barrel locking station blocks the packaging barrel. The rollers of the copper hoop locking station conveyor line 10 start to rotate. 12) Packaging barrel 13 flows along conveyor line 10 toward the barrel clamp pin station; 13) When the packaging barrel detection sensor 11 set on the pin station of the barrel hoop detects the packaging barrel 13, the conveyor line 10 on the pin station of the barrel hoop stops rotating, the lifter 12 set on the pin station of the barrel hoop blocks the packaging barrel and stops the flow of the packaging barrel 13, and a pair of arc-shaped barrel clamps clamp the packaging barrel. 14) The camera 81 of the pin hole recognition device identifies the position of the handle pin hole 15a; 15) The computer 83 transmits the deviation value of the handle pin hole 15a position to the controller; 16) The controller issues instructions based on the values ​​transmitted by the computer to correct the stroke and rotation angle of the three-dimensional lead screw module 70 and the rotating device 76 with a small-stroke lifting clamping cylinder. 17) The three-dimensional lead screw module 70 and the rotating device 76 with the small stroke lifting clamping cylinder 77 descend according to the modified parameters, clamp the locking pin 17 of the outlet of the vibrating hopper 90, move to the top of the handle pin hole 15a and descend to insert into the handle pin hole 15a. The rotating device 76 with the small stroke lifting clamping cylinder 77 is offset from the position above the handle pin hole 15a. 18) The camera of the pin hole recognition device identifies the position of the handle pin hole and confirms the insertion position. 19) If the position is incorrect, the small-stroke lifting clamping cylinder 77 removes the locking pin 17 and repeats the above steps 14)-18). After three failures, the buzzer will sound an alarm. 20) When the insertion position is correct, the small-stroke lifting clamping cylinder rotates 180° under the drive of the rotating device, and the locking pin pressing part 79 on its back presses down the locking pin tail. 21) Complete the insertion of the locking pin.

[0035] The positive effects of this invention are as follows: By installing a packaging barrel 13 detection sensor 11 between the rollers of the barrel clamping station conveyor line 10 on the production line, when the packaging barrel 13 is detected to be in position, a limiter 12 installed on the conveyor line blocks the packaging barrel 13 and stops the rotation of the rollers of the barrel clamping station conveyor line 10, preventing the packaging barrel 13 from flowing backward in the production line and avoiding collisions and accumulation between the packaging barrels 13; the limiter 12 can release the packaging barrel 13 during its flow and block the product for positioning when it needs to stop; by installing a barrel clamping station and a barrel clamping station... A barrel hoop transfer device 40 is installed between the positions, which can clamp and transport the barrel hoop 47 to the barrel hoop support plate 50a and barrel hoop support plate 50b during the stopping process of the packaging barrel 13, thereby locking the barrel hoop 47. By setting horizontal slide rails 24 perpendicular to the conveying direction of the conveyor line 10 at the bottom of the supports on both sides of the conveyor line 10, an angle rotation motor 23 installed in the base 21 below the conveyor line 10 can be used to drive the supports on both sides to move synchronously along the vertical direction of the conveyor line 10 by rotating around the central axis. When it is close to the packaging barrel 13 in the conveyor line 10, the packaging barrel clamping device set in the middle of the support can be used. The barrel clamps 32a and 32b of the device 30 clamp the packaging barrel 13, ensuring its stable placement and preventing displacement or shaking of the barrel clamp 47 during the locking process. Simultaneously, the barrel top clamps 35a and 35b, positioned opposite each other on either side of the top conveyor line 10 of the support frame, clamp the upper edge of the packaging barrel 13. The barrel clamp support plate on the upper surface of the barrel top clamps can receive the barrel clamps transported by the barrel clamp transfer device 40. By installing lifting devices on a pair of supports, packaging barrels 13 of different heights can be accommodated, meeting the needs of multi-variety production. The barrel clamp transfer device 40... A top cover clamping device 60 is installed on the support leg. The top cover clamping device 60 rotates to the top cover 14 of the packaging barrel 13 and presses down. This can stabilize the top cover 14 during the locking process of the barrel hoop 47, preventing the top cover 14 from shifting during the locking process, which would cause abnormal locking or offset locking problems. At the same time, it is conducive to the separation between the multiple barrel hoop transfer magnets 45 of the barrel hoop transfer device 40 and the barrel hoop 47, returning to the starting position of the arc-shaped sliding guide hole. By rotating the top cover clamping device 60 to be set on the support leg of the barrel hoop transfer device 40, it can be rotated to the outside of the center of the conveyor line 10 to prevent it from affecting the normal handling of the barrel hoop 47.By setting barrel hoop support plate 50a and barrel hoop support plate 50b on the top of the upper part 33 of the upper support, the upper edge of the packaging barrel 13 can be clamped, and the barrel hoop 47 transported by the barrel hoop transfer device 40 can be received and supported. Under the clamping and supporting condition, the rotation cylinder 56 of the barrel hoop rotation positioning mechanism drives the active rotation mechanism 58 to rotate along the arc-shaped sliding guide hole, so that the active rotation mechanism 58 drives the driven rotation mechanism 59 to approach the barrel hoop 47 from far to near. The barrel hoop 47 is attracted by the magnet and rotated synchronously. During the rotation, the end 49 of the barrel hoop enters the positioning groove 53a of the barrel hoop positioning block 53, and the barrel hoop is positioned in the positioning groove 53a. Inside, the clamping roller of the locking mechanism pushes the locking handle 48 to rotate in the opposite direction of the rotation direction of the barrel hoop 47 along the locking guide hole 54, pressing the locking handle 48 close to the outer periphery of the barrel hoop 47 to achieve locking of the barrel hoop. After locking, the barrel hoop locking mechanism returns to the starting position, the lifting clamping plate 66 set below the horizontal rotating arm 64 of the top cover clamping device 60 rises and rotates back to the starting position, and the fixing clamp of the clamping device and the barrel hoop support plate 50a and barrel hoop support plate 50b move to both sides away from the packaging barrel 13 under the drive of the angle rotation motor 23. The limiter 12 releases, and the conveyor line 10 on the barrel hoop locking station starts. As the packaging drum 13 rotates, it flows to the next station, locking the locking handle 48 around the outer circumference of the drum hoop 47 to prevent the drum hoop 47 from opening. A pin hole identification device 80 is installed at the pin station on the drum hoop to detect the position coordinates of the handle pin hole 15a and feeds the coordinate information back to the production line controller. The controller can adjust the position of the three-dimensional lead screw module 70 according to the coordinate position. The rotating device 76 with a small-stroke lifting clamping cylinder 77 can rotate the locking pin 17 to align it with the handle pin hole 15a. Another function of the rotating device 76 is to rotate 180° after the locking pin 17 is inserted, pressing the locking pin 17 down. The component rotates to above the pin tail 18b, causing the locking pin pressing component 79 to descend within a short stroke, fully inserting the locking pin 17 into the handle pin hole 15a. By setting the cylinder 77 to move to a short stroke lifting and clamping position, it can achieve both short-stroke lifting and clamping of the locking pin 17, as well as pressing down on the locking pin 17. Using this invention, malfunctions during the locking process of packaging barrels can be reduced, preventing jamming and alarms during production, reducing the risk of product contact caused by production line malfunctions, ensuring smooth production line operation, and preventing accidental opening of barrel hoops that could lead to poisoning risks to humans and animals.

6. The automatic barrel hoop locking and locking pin insertion production system in a barrel bottling production line according to claim 1, characterized in that: The illumination of the pin hole recognition device is located around the camera, and the illumination light is a monochromatic light that is different from the surrounding light. The information exchange steps between the computer of the pin hole recognition device and the production line controller are as follows: 1) When the packaging barrel detection sensor installed on the pin station of the barrel hoop detects the packaging barrel, the conveyor line stops rotating. The limiter installed on the pin station of the barrel hoop restricts the movement of the packaging barrel, stops the packaging barrel from moving forward and positions it. 2) The camera of the pin hole recognition device identifies the position of the handle pin hole, obtains the position of the handle pin hole, and calculates the deviation between the actual position and the set position; 3) The computer transmits the deviation value of the handle pin hole position to the controller; 4) The controller issues instructions based on the values ​​transmitted by the computer to correct the X, Y, and Z direction deviations and rotation angle deviations between the parameters of the three-dimensional lead screw module and the rotating device with the small-stroke lifting clamping cylinder and the set position of the handle pin hole. 5) The three-dimensional lead screw module and the rotating device with a small-stroke lifting clamping cylinder move and descend according to the corrected parameters, clamp the locking pin of the vibrating hopper outlet, and then move to the top of the handle pin hole to pre-insert the locking pin into the handle pin hole of the barrel hoop. 6) The locking pin identification system checks the position difference between the locking pin and the handle pin hole again. If there is an error, the small-stroke lifting clamping cylinder removes the erroneous locking pin; the above actions 2)-5) are performed again. After three failures, the buzzer alarms; if there is no error, the small-stroke lifting clamping cylinder rotates 180° under the drive of the rotating device, and the locking pin pressing part on its back presses down the locking pin tail. 7) Complete the information exchange between the computer and the production line controller.

7. A method for automatic locking of barrel hoops and insertion of locking pins in a barrel bottling production line, utilizing the automatic locking of barrel hoops and insertion of locking pins in a barrel bottling production line as described in any one of claims 1-6, characterized in that: The automatic locking and pin insertion method for barrel hoops in the barrel bottling production line is as follows: 1) Packaging barrels with top lids are conveyed to the barrel clamping station on the conveyor line; 2) After entering the barrel hoop locking station, it is detected by the packaging barrel detection sensor and the information is fed back to the controller; 3) After receiving the controller command, the limit switch of the packaging barrel on the conveyor line stops the conveyor line at the barrel hoop locking station and the limit switch blocks the forward movement of the packaging barrel. 4) The packaging barrel clamping device is equipped with a pair of arc-shaped barrel body clamps and a pair of arc-shaped barrel top clamps to clamp the packaging barrel; 5) The barrel hoop transfer device moves the barrel hoop from the barrel hoop setting station to a pair of barrel hoop support plates at the barrel hoop locking station. The barrel hoop clamping mechanism clamps the barrel hoop around its perimeter. After the barrel hoop transfer device rises, it returns to the starting position. 6) Rotate the top cover clamping device to the top of the packaging tube and press down the top cover; 7) The barrel hoop rotating mechanism drives the barrel hoop to rotate. 8) The barrel hoop is positioned by the positioning mechanism; 9) The barrel hoop clamping mechanism clamps the barrel hoop again, and the barrel hoop rotating mechanism returns to the starting position; 10) The barrel hoop locking mechanism completes the locking of the barrel hoop, and the top cover pressing device rises and rotates back to the starting position near the support leg; 11) The barrel clamping mechanism, barrel clamping mechanism, arc-shaped barrel body clamp and barrel top clamp on the packaging barrel support return to the starting position away from the packaging barrel and barrel clamp, the limit switch releases, and the conveyor rollers start to rotate; 12) The packaging drums flow along the conveyor line toward the drum hoop pinning station; 13) When the packaging barrel detection sensor installed at the barrel clamp pin station detects the packaging barrel, the conveyor line stops rotating, and the lifting limiter installed at the barrel clamp pin station prevents the packaging barrel from moving forward, and the packaging barrel stops. 14) The camera of the pin hole recognition device identifies the position of the handle pin hole. 15) The computer transmits the deviation value of the handle pin hole position to the controller; 16) The controller issues instructions based on the values ​​transmitted by the computer to correct the stroke and rotation angle of the three-dimensional lead screw module and the rotating device with a small-stroke lifting clamping cylinder. 17) The three-dimensional lead screw module and the rotating device with a small-stroke lifting clamping cylinder descend according to the corrected parameters, clamp the locking pin of the vibrating hopper outlet, move to the top of the barrel hoop handle pin hole and descend to insert into the handle pin hole, and then the rotating device with the small-stroke lifting clamping cylinder deflects the position. 18) The camera of the pin hole recognition device identifies the position of the handle pin hole and confirms the insertion position; 19) If the position is incorrect, the small-stroke lifting clamping cylinder removes the locking pin and repeats the above steps 14)-18). After three failures, the buzzer will sound an alarm. 20) When the insertion position is correct, the small-stroke lifting clamping cylinder rotates 180° under the drive of the rotating device, and the locking pin pressing part on its back presses down the locking pin tail. 21) Complete the insertion of the locking pin.
