Description

Technical Field

[0001] This application relates to the technical field of automated production of packaging bags, and in particular to a clip-type automatic feeding and labeling machine and its operating method. Background Technology

[0002] Packaging bag labeling refers to the process of accurately affixing labels (such as product information labels, barcodes, QR codes, etc.) to the surface of packaging bags; Traditional packaging bag labeling production lines are usually composed of independent equipment. For example, after the feeding machine completes the stacking and unloading, the packaging bags need to be placed on the conveyor belt manually. The conveyor belt is used to transport the packaging bags to the labeling station for labeling. When labeling, the operator needs to visually judge that the product has arrived at the labeling station and then manually trigger the labeling machine. If two bags are found to be stuck together, the machine needs to be stopped and the bags need to be sorted manually. This type of packaging bag labeling method relies heavily on semi-automated equipment, and the connection between each link depends on manual adjustment. This can easily lead to a mismatch between the manual feeding speed and the equipment conveying speed, resulting in material accumulation or insufficient supply. At the same time, it can also easily trigger labeling delays, affecting production efficiency and labeling accuracy.

[0003] Therefore, there is an urgent need for a magazine-type automatic feeding labeling machine and its operation method to solve the above problems.

If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed in this application.

[0021] Please refer to Figure 1 In one embodiment, a magazine-type automatic feeding labeling machine includes a base 1 and a first mounting plate 2. The first mounting plate 2 is vertically mounted on the base 1 and a lifting assembly 3 is provided on the first mounting plate 2. A material tray 4 is slidably mounted on the base 1 and connected to the lifting assembly 3. The material tray 4 has at least one placement station. A conveying module 5 is provided on the first mounting plate 2 above the lifting assembly 3. A suction belt conveyor 6 is provided on one side of the base 1. The suction belt conveyor 6 is used to adsorb and convey the product. A support frame 7 is provided above the suction belt conveyor 6. A labeling mechanism 8 is provided on the support frame 7. The labeling mechanism 8 can be adjusted in multiple directions on the support frame 7. The lifting assembly 3, the handling module 5, the suction belt conveyor 6, and the labeling mechanism 8 are electrically connected to the control box 9.

[0022] It is understandable that the automatic feeding and precise transfer of stacked materials are achieved through the coordinated work of the lifting component 3 and the handling module 5, eliminating the efficiency bottleneck and speed mismatch caused by manual handling. At the same time, the suction belt conveyor 6, combined with the negative pressure adsorption function, ensures that the packaging bag is in a stable position during transportation and avoids deviation. With the multi-directional adjustment capability of the labeling mechanism 8, the label and the workstation are dynamically aligned, avoiding labeling delays or misalignments caused by manual triggering. The entire process does not require manual intervention, significantly improving production efficiency and labeling accuracy, and is especially suitable for large-scale automated production scenarios.

[0023] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 Based on the above embodiments, the lifting assembly 3 includes a first motor 31, a first synchronous belt assembly 32, a first track 33, a first slider 34, a lifting plate 35, a first sensor 36, and a sensing plate 37. A third mounting plate is provided on the first mounting plate 2. Several first motors 31 are provided on the third mounting plate via a motor fixing plate. The output end of the first motor 31 is connected to one end of the first synchronous belt assembly 32, and the other end of the first synchronous belt assembly 32 is connected to the third mounting plate. The third mounting plate is provided with a first track 33, a first slider 34 is slidably connected to the first track 33, and one end of the first slider 34 is connected to the first synchronous belt assembly 32. The other end of the first slider 34 is connected to a lifting plate 35, and the lifting plate 35 is connected to the material tray 4. The third mounting plate is provided with a first sensor 36, and the lifting plate 35 is provided with a sensor plate 37, which can pass through the first sensor 36.

[0024] Further, please refer to Figure 4 It also includes a third sensor 15, which is connected to the base 1 via a fixed rod. The material tray 4 can slide relative to the fixed rod. The third sensor 15 is used to detect the rising height of the material tray 4. However, when the preset rising height of the material tray 4 is detected, the control box 9 controls the first synchronous belt assembly 32 to stop the rising of the material tray 4. The first sensor 36 and the sensor detect the falling position of the material tray 4, thereby triggering the control box 9 to control the first synchronous belt assembly 32 to stop the falling of the material tray 4.

[0025] Specifically, please refer to Figure 1 , Figure 4 Based on the above embodiments, it also includes an adjustment component 10, which is used to limit the product placed on the material tray 4. Several adjustment components 10 are provided on the base 1. The several adjustment components 10 are distributed in a rectangular array with the center of the material tray 4 as the reference, and are located at the four edges of the material tray 4 respectively. The adjustment assembly 10 includes a second track 101, a second slider 102, a connecting plate 103, and a guide rod 104. The second track 101 is provided on the base 1, and the second slider 102 is slidably arranged on the second track 101. The connecting plate 103 is provided on the second slider 102. The connecting plate 103 is connected to one end of the guide rod 104, and the other end of the guide rod 104 extends away from the base 1 through the material tray 4. The second track 101 and the second slider 102 are connected by a locking assembly 105. The locking assembly 105 can be a handle screw or bolt, etc. By tightening the handle screw or bolt, the second slider 102 is locked on the second track 101. To release it, simply rotate in the opposite direction.

[0026] Further, please refer to Figure 4 It also includes adjustment holes (not shown in the figure), with several adjustment holes symmetrically distributed with the center of the material tray 4 as the reference, and the guide rod 104 passes through the adjustment holes and connects to the material tray 4.

[0027] It is understandable that by adjusting the position of the guide rod 104 in the adjustment hole, it can be adapted to packaging bags of various sizes, thus improving the application range of this device. When in use, the guide rod 104 is used to limit the edge of the packaging bag, which can ensure that the packaging bag does not move during the lifting process and provide the accuracy of suction from the nozzle 56.

[0028] Specifically, please refer to Figure 1 , Figure 5 Based on the above embodiments, the handling module 5 includes a module fixing plate 51, a linear drive module 52, a profile arm 53, a picking cylinder 54, a picking plate 55, and a suction nozzle 56. The module fixing plate 51 is connected to the first mounting plate 2. A linear drive module 52 is provided on the module fixing plate 51. The output end of the linear drive module 52 is connected to one end of the profile arm 53. The other end of the profile arm 53 is connected to a material picking cylinder 54. The output end of the material picking cylinder 54 is connected to a material picking plate 55. Several suction nozzles 56 are provided on the material picking plate 55.

[0029] Preferably, the linear drive module 52 is a linear motor. The material handling module 5 replaces manual handling, enabling continuous high-speed operation for a long time, avoiding deviations caused by manual placement, improving the labeling qualification rate, and also preventing fingerprints from being left on the packaging bags when they are manually separated.

[0030] Specifically, please refer to Figure 1 , Figure 6 , Figure 7 Based on the above embodiments, the suction belt conveyor line 6 includes a profile frame 61, a second synchronous belt assembly, a wind box 62, a suction fan 63, and a suction duct. A second synchronous belt assembly is provided on the profile frame 61. The annular belt 64 on the second synchronous belt assembly has several through holes. The air box 62 is located in the inner circumferential space of the annular belt 64, and the air outlet of the air box 62 is directly opposite the through holes on the annular belt 64. The air box 62 is connected to the profile frame 61 through the support plate 13. A suction fan 63 is installed on the profile frame 61 below the second synchronous belt assembly, and the air box 62 and the suction fan 63 are connected by a suction pipe.

[0031] It is understood that the second synchronous belt assembly includes a driving roller assembly, a driven roller assembly, and an annular belt 64. The driving roller assembly and the driven roller assembly are connected by the annular belt 64. The driving roller assembly has a built-in motor or electric motor for driving. By setting up the suction belt conveyor 6, the packaging bags placed on the annular belt 64 can be stably transported, avoiding problems such as packaging bag position deviation affecting labeling accuracy.

[0032] Specifically, please refer to Figure 1 , Figure 8 Based on the above embodiments, the labeling mechanism 8 includes a longitudinal moving component 81, a feeding component 82, a tensioning component 83, a driving component 84, a label peeling plate 85, and a receiving rod 86. A longitudinal moving component 81 is provided on the support frame 7. The longitudinal moving component 81 is connected to a second mounting plate 12 through a guide seat 11. A support plate 13 is provided below the second mounting plate 12. A feeding component 82 is provided on one side of the support plate 13. The support plate 13 is provided with several guide rollers. A tensioning component 83 is provided on one side of the support plate 13 and a label peeling plate 85 is provided on the support plate 13 on one side of the tensioning component 83. A receiving rod 86 is provided on the support plate 13 on the other side of the tensioning component 83. The tensioning component 83 and the receiving rod 86 are connected by a drive component 84.

[0033] Preferably, please refer to Figure 9 The longitudinal moving assembly 81 includes a mounting base, a guide rod, a lead screw, and an operating handle. The slide rail is provided with a mounting base, and the two mounting bases are connected by two guide rods, which pass through the mounting bases. A lead screw is provided between the two guide rods, and one end of the lead screw passes through the guide seat 11 and is rotatably connected to one of the mounting seats. The other end of the lead screw passes through the other mounting seat and extends outward to be connected to an operating handle. Preferably, please refer to Figure 10 The tensioning assembly 83 includes a fixed frame, a fixed pressure roller, an eccentric pressure roller, a pressing handle 16, and a handle limiting block; A fixed frame is provided on the support plate 13. One end of the fixed pressing roller is rotatably connected to the fixed frame, and the other end of the fixed pressing roller passes through the support plate 13 and is connected to the drive assembly 84. One end of the eccentric pressing roller 823 is connected to the support plate 13, and the other end of the eccentric pressing roller extends outward through the fixed frame and is connected to the pressing handle 16. A handle limit block is provided on the fixed frame.

[0034] It is understood that the clamping handle 16 is provided with a set screw hole and a threaded hole for locking and clamping. The eccentric shaft of the eccentric pressing roller is connected to the clamping handle 16 and communicates with the set screw hole. When the clamping handle 16 is rotated to the position, the eccentric shaft of the eccentric pressing roller is fixed by tightening the set screw, so that it cannot rotate. When it is necessary to loosen, the clamping handle 16 can be easily loosened by simply rotating it in the opposite direction, that is, clockwise rotation is to loosen and counterclockwise rotation is to clamp.

[0035] The drive assembly 84 includes a second motor, a first synchronous belt assembly 32, and a second synchronous belt assembly 32. The second motor is mounted on the support plate 13. One end of the first synchronous belt assembly 32 is connected to the output end of the second motor, and the other end of the first synchronous belt assembly 32 is connected to the fixed film pressing roller. One end of the second synchronous belt assembly 32 is coaxially connected to the fixed film pressing roller, and the other end of the second synchronous belt assembly 32 is connected to the take-up rod 86. The second motor simultaneously drives the take-up rod 86 and the fixed film pressing roller to rotate, thereby achieving the pulling and winding of the label tape.

[0036] Specifically, please refer to Figure 8 , Figure 10 Based on the above embodiments, a detection component 14 is also included. The detection component 14 is provided on the support plate 13 above the label stripping plate 85. The detection component 14 includes a support rod 1401, a sliding block 1402, an adjusting block 1403, an optical fiber fixing block 1404, and a first detection optical fiber 1405. The support rod 1401 is connected to the support plate 13. A sliding block 1402 is provided on the support rod 1401. A sliding groove is provided on the sliding block 1402. An adjusting block 1403 is connected to the sliding groove. An optical fiber fixing block 1404 is provided on the adjusting block 1403. A first detection optical fiber 1405 is provided on the optical fiber fixing block 1404.

[0037] It is understandable that the first detection fiber optic cable 1405 is used to detect the fiber optic detection holes on the label paper tape. By detecting the position of these detection holes, it is determined whether the label paper tape has reached the correct labeling position, ensuring that the label is strictly synchronized with the labeling position of the packaging bag when it is peeled off. Specifically, when the fiber optic cable detects the detection hole of the label paper tape, it sends a signal to the control box 9 to control the third motor to start and drive the label paper tape to move a distance of one labeling position. This synchronization mechanism can prevent label misalignment or omission.

[0038] Specifically, please refer to Figure 8 , Figure 12 , Figure 13 Based on the above embodiments, the feeding assembly 82 includes a mounting plate 821, a pressure plate 822, a fixing block 823, a tensioning block 824, a handle screw 825, a buffer assembly 826, and a second sensor 827. The mounting plate 821 is connected to the support plate 13 via the fixing plate 17. The mounting plate 821 is provided with a feeding mandrel, and the pressure plate 822 is provided on the feeding mandrel. The pressure plate 822 is provided with at least two fixing blocks 823. The fixing blocks 823 are provided with handle screws 825. The end of the handle screws 825 near the pressure plate 822 is connected to a tension block 824, and the tension block 824 is slidably connected to the pressure plate 822. The buffer assembly 826 includes a tension plate 8261, a limiting roller, a screw 8263, and a tension spring 8264; A tensioning plate 8261 is rotatably connected to the side of the fixed plate 17 away from the mounting plate 821. A limit roller is provided at the end of the tensioning plate 8261 away from the fixed plate 17, and the tensioning plate 8261 is connected to the screw 8263 provided on the fixed plate 17 through a tension spring 8264. The screw 8263 can move relative to the fixed plate 17. The fixed plate 17 is equipped with a second sensor 827 through a multi-directional adjustment module. The specific structure of the multi-directional adjustment module can be referred to the multi-directional adjustment structure or method of the first detection fiber optic cable 1405, and will not be described again here. The second sensor 827 can detect the label balance and tape feeding status, and will immediately trigger an alarm when the paper tape breaks or runs out.

[0039] It is understood that, further, the pressure plate 822 consists of a large-diameter cylinder, a small-diameter cylinder, and a pressure plate. The large-diameter cylinder and the small-diameter cylinder are coaxially arranged, and a pressure plate is arranged between the large-diameter cylinder and the small-diameter cylinder. The fixing block 823 is located on the small-diameter cylinder. One end of the tensioning block 824 is located in the fixing block 823 and is slidably connected to the fixing block 823. The other end of the tensioning block 824 is slidably connected to the large-diameter cylinder. A pin hole is opened on the fixing block 823, and a rotating pin is arranged in the pin hole. When the handle screw 825 is tightened... At this time, the tension block 824 located at the fixed block 823 retracts inward, and the tension block 824 located inside the large-diameter cylinder opens outward. Because the inner rings at both ends of the label tape are pressed by the large-diameter cylinder, the tension block 824 located at the fixed block 823 opens and presses against the inner ring of the label roll. The tighter it is tightened, the greater the tension. The label tape is fixed by the tension of the tension block 824 located inside the large-diameter cylinder. That is, the radial movement of the handle screw 825 drives the bidirectional movement of the tension block 824, thereby generating radial tension to press the inner ring of the label tape.

[0040] An operating method for a cartridge-type automatic feeding labeling machine, applicable to the aforementioned cartridge-type automatic feeding labeling machine, includes the following steps: S1. Stack the products to be labeled on the placement station of the material tray 4, and limit the products in four directions by adjusting the guide rod 104 of the component 10. S2. The first motor 31 of the control lifting assembly 3 drives the first synchronous belt assembly 32, which in turn drives the lifting plate 35 and the material tray 4 to rise along the first track 33 to a preset height and then stops rising. When the sensing plate 37 triggers the first sensor 36, the descent stops. S3, the linear drive module 52 of the conveying module 5 drives the profile arm 53 to move to the material position. After the picking cylinder 54 drives the suction nozzle 56 to pick up the product, the product is transferred to the suction belt conveyor line 6. S4. Start the suction fan 63 to create negative pressure in the air box 62 through the suction pipe, so that the product is adsorbed on the annular belt 64 with through holes for conveying. S5. The feeding component 82 of the labeling mechanism 8 releases the label tape. After the tension is adjusted by the tensioning component 83, the driving component 84 drives the label tape to peel off the label through the peeling plate 85. At the same time, the longitudinal moving component 81 adjusts the height of the peeling plate 85 so that the label is accurately attached to the product surface. S6. The peeled label backing paper is recycled by the receiving rod 86; S7. Repeat steps S1-S6 until all products are labeled.

[0041] Specifically, based on the above embodiments, the operation of the feeding component 82 in step S5 includes: S51, Rotate the handle screw 825 to adjust the clamping force of the tension block 824 on the label roll; S52. The tension of the limiting roller on the label tape is adjusted by the tension of the tension spring 8264 of the buffer assembly 826; S53. The second sensor 827 is used to monitor the remaining amount of the tag. When the remaining amount is insufficient, an alarm is issued through the control box 9.

[0042] In summary, when using a clip-type automatic feeding and labeling machine, the operator places the stacked packaging bags on the placement station of the material tray 4, adjusts the position of the guide rod 104 in the adjustment hole according to the size of the packaging bags to ensure that the packaging bags are stacked neatly and prevent displacement. After the feeding is completed, the control box 9 controls the first motor 31 to rotate, and the first motor 31 drives the synchronous belt to rotate, thereby realizing the rise of the lifting plate 35 and the material tray 4. When the material tray 4 lifts the stacked packaging bags to enter the detection range of the second sensor 827, the second sensor 827 sends a signal to the control box 9, the first motor 31 stops rotating, and the material tray 4 stops rising. At this time, the linear motor drives the profile arm 53 to move towards the material tray 4. When the picking plate 55 moves directly above the material tray 4, the picking cylinder 54 extends, driving the picking plate 55 and the suction nozzle 56 to move towards the packaging bag. At this time, the control box 9 triggers the solenoid valve assembly and vacuum generator set on the first mounting plate 2, so that the suction nozzle 56 generates negative pressure to adsorb the packaging bag. After adsorption is completed, the picking cylinder 54 starts the shaking mode during the initial rising stage. The cylinder achieves short-range reciprocating motion through the rapid reversal of the solenoid valve, and uses inertia to separate the packaging bags that may be adsorbed (the lower layer of bag falls off due to gravity). The shaking duration is set by the built-in program of the control box 9. After the shaking ends, the picking cylinder 54 is completely reset, and the linear motor drives the profile arm 53 and the suction nozzle 56 with the adsorbed packaging bag to be transferred to the suction belt conveyor line 6. The suction belt conveyor 6 is equipped with a designated area for placing packaging bags. The packaging bags are placed on the designated area of ​​the annular belt 64 by the handling module 5. The annular belt 64 is driven to rotate by the active roller assembly. During the rotation, the suction fan 63 generates a stable negative pressure, which is transmitted to the air box 62 through the suction pipe and then acts precisely on the through hole of the annular belt 64 through the air outlet to form a uniformly distributed adsorption force field. This ensures that the packaging bags are always in close contact with the belt during the conveying process and that the packaging bags will not shift or fall off during the conveying process. Subsequently, according to the preset program, the annular belt 64 transports the packaging bag to the preset position of the labeling station for labeling. The label tape used in this application is a release paper label. Before labeling, the operator loosens the handle screw 825, removes the pressure plate 822 as a whole, and installs the label tape in a roll onto the feeding mandrel, tightly adhering to the surface of the mounting plate 821. Then, the pressure plate 822 is installed, and the label tape is... Figure 8 Thread the film through the correct direction and wind the label tape onto the take-up bar 86 as many points as possible so that the take-up bar 86 can collect the tape normally when the work starts. The operating clamping handle 16 is rotated toward the handle limit block. The clamping handle 16 drives the eccentric film pressing roller to move upward. Because the eccentric film pressing roller has an eccentric structure, when it rotates, the clamping handle 16 can press the label paper tape between the eccentric film pressing roller and the fixed film pressing roller after it is in position. The surface of the fixed film pressing roller is knurled to prevent slippage during rotation, and the surface of the eccentric film pressing roller is made of rubber so that the paper tape can be easily and smoothly pulled during rotation. After installing the label tape, align the first detection fiber 1405 with the fiber detection hole on the label tape. The sliding block 1402 can adjust the vertical position of the fiber on the support rod 1401, and the adjusting block 1403 can adjust the front and back position on the sliding groove on the sliding block 1402. The fiber fixing block 1404 can move left and right on the adjusting block 1403 by means of the sliding groove on the upper part. After the above adjustment, the adjusted position can be fixed by inserting bolts and nuts. Through the above adjustment method, the first detection fiber 1405 can be aligned with the fiber detection hole on the label tape. When the second inspection fiber optic cable on the belt conveyor detects the packaging bag, the third motor starts, driving the third and fourth synchronous belt assemblies to move together, carrying the label paper tape to a labeling position and applying the label according to the set parameters. Specifically, driven by the third motor, the fixed film pressing roller and the take-up rod 86 move together. Because the fixed film pressing roller and the eccentric film pressing roller clamp the label paper tape, the label paper tape is pulled towards the take-up rod 86 during rotation. Under the blade state in front of the label peeling plate 85, the label is automatically peeled off the label paper tape and pasted onto the packaging bag on the belt conveyor. During the rotation of the third motor, the label tape is pulled by the traction force of the third motor. During the pulling process, the label tape on the feeding assembly 82 is also fed forward. The two limit rollers on the feeding assembly 82 play a guiding role to prevent the label tape from going out of place during the pulling process. One of the limit rollers is connected to the tension plate 8261 at the rear end of the fixed plate 17. The tension plate 8261 is connected to the tension spring 8264 and the screw 8263. Under the traction of the third motor, this limit roller will swing at an angle. Under the action of the tension spring 8264, it plays a buffering role. When the third motor stops working, it returns to the initial state due to the action of the tension spring 8264. When the label tape is used up, the sensor installed on the fixed plate 17 detects that there is no material, the equipment stops working and alarms, prompting the operator to replace the label tape. Through the above steps, the automatic feeding and automatic labeling of the packaging bags are completed. The front-end material-picking cylinder 54 picks up materials in a cycle, while the rear-end second detection fiber optic cable is always in a detection state. Once the packaging bag is detected, a signal is provided to the labeling mechanism 8, which then starts to operate and apply the label. This process is repeated continuously to complete the labeling process of the remote control packaging bag. Throughout the labeling process, operators only need to periodically inspect the materials in the silo and the labels on the labeling mechanism 8, which greatly reduces the workload of operators and increases labeling efficiency and quality.
