Description

Technical Field

[0001] The present invention relates to the technical field of cartoning machines, and particularly to a cartoning machine with variable bin pitch. Background Art

[0002] A cartoning machine is a machine integrating electricity, optics, machinery, pneumatics, etc., and is applicable to mechanical automatic machines for plate-shaped and bottled products such as pharmaceuticals, foods, and health products. It automatically completes processes such as product conveying, folding and conveying of instruction manuals, carton forming and conveying, loading of products and instruction manuals into cartons, folding and sealing of the tongues at both ends of the cartons, and automatically rejects unqualified products, and can automatically stop and alarm in case of cartoning errors. The models of cartoning machines are often divided according to the bin pitch of the material conveying line in the cartoning machine. For example, if the bin pitch is 4 inches, it is called a 4-inch machine; if the bin pitch is 6 inches, it is called a 6-inch machine; if the bin pitch is 8 inches, it is called an 8-inch machine, and so on.

[0003] A cartoning machine generally consists of a material conveying line (composed of a product conveying line, a carton conveying line, and an instruction manual conveying line), an instruction manual folding machine, a product loading mechanism, a box taking and opening mechanism, a rotary pushing mechanism, a box closing execution mechanism, an output belt line and other modules. Firstly, in the existing design, the bin pitch in the product conveying line and the carton conveying line and the gripper in the instruction manual conveying line are fixed and cannot be changed, resulting in the fixed bin pitch of the cartoning machine that cannot be changed. Secondly, in the existing design, the speed ratios of each module in the drive system are fixed and cannot be adjusted. Even if the bin pitch can be changed, it cannot be applicable to the adjusted bin pitch. Therefore, the existing cartoning machines can only be applicable to cartons of a certain size range, ultimately resulting in low compatibility of the cartoning machine with the size of cartons and reduced application range.

[0004] Therefore, a cartoning machine with variable bin pitch is proposed to solve the above problems. Summary of the Invention

[0005] The present invention provides a cartoning machine with variable bin pitch.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] An embodiment of the present invention provides a cartoning machine with variable bin pitch, as Figure 1-2 shown, which includes a frame and a driving device 1, a product conveyor line 2, an instruction manual conveyor line 6, a carton conveyor line 8, an instruction manual folding machine 3, an instruction manual pusher 4, an instruction manual triangular conveyor line 5, a rotary pusher device 7, a box taking and opening device 9, and a box closing device 10 provided on the frame. Among them, the product conveyor line 2 is used to transport the product 24, and the instruction manual conveyor line 6 is used to transport the instruction manual 54. Correspondingly, the instruction manual triangular conveyor line 5 is located at the instruction manual inlet of the instruction manual conveyor line 6. The instruction manual folding machine 3 is used to fold the instruction manual 54. The instruction manual pusher 4 is located on the left side of the instruction manual triangular conveyor line 5 and is used to transport the folded instruction manual 54 by the instruction manual folding machine 3 onto the instruction manual triangular conveyor line 5. The rotary pusher device 7 is located at the output end of the product conveyor line 2 and is used to transport the product 24 on the product conveyor line 2 and the instruction manual 54 on the instruction manual conveyor line 6 to the carton conveyor line 8 together. The box inlet end of the carton conveyor line 8 is located at the outlet end of the instruction manual conveyor line 6. The box inlet end of the carton conveyor line 8, the instruction manual outlet end of the instruction manual conveyor line 6, and the outlet end of the product conveyor line 2 overlap in the horizontal direction, so that the output end of the rotary pusher device 7 can transport the product 24 and the instruction manual 54 upward into the carton 81 on the carton conveyor line 8 together. The box taking and opening device 9 is located at the box inlet of the carton conveyor line 8 and is used to take the box and open the carton 81 to facilitate the transportation of the instruction manual 54 and the product 24 from the front. The box closing device 10 is located at the end of the box outlet of the carton conveyor line 8 and is used to perform the box closing operation on the carton 81 after the cartoning is completed.

[0043] Specifically, the product conveyor line 2, the instruction manual conveyor line 6, and the paper box conveyor line 8 can adjust the pitch of the bins thereon, and the pitch distances of the bins after the three are adjusted are the same. Correspondingly, the instruction manual triangular conveyor line 5 can adjust the distance between two adjacent grippers 53 thereon to match the adjusted bin pitch, and the rotary pusher device 7 can adjust the distance between two adjacent push rods 71 thereon to match the adjusted bin pitch on the product conveyor line 2. When the user needs to process other-sized boxes, the bin pitch on the product conveyor line 2, the instruction manual conveyor line 6, and the paper box conveyor line 8, the distance between the grippers 53 on the instruction manual triangular conveyor line 5, and the distance between two adjacent push rods 71 on the rotary pusher device 7 can be adjusted to achieve the required bin pitch. Among them, the bin pitch is the sum of the width of the bin and the distance between two bins. If the width of the bin is changed without changing the distance between two bins, the change in the bin width will still be limited. Therefore, changing the bin pitch can enable a larger range of adjustment of the width of the entire bin. Therefore, this application realizes a larger range of compatibility with a larger range of sizes of paper boxes 81 by changing the bin pitch; among them, as Figure 2 shown, H1 is the bin pitch on the product conveyor line 2, H2 is the bin pitch on the instruction manual conveyor line 6, and H3 is the bin pitch on the paper box conveyor line 8.

[0044] Specifically, the driving device 1 includes a driving member 11, a driving mechanism, a first speed-changing mechanism 15, a second speed-changing mechanism 16, and a third speed-changing mechanism 19. The driving member 11 is drivingly connected to the input end of the driving mechanism. The product conveying line 2, the instruction manual conveying line 6, and the paper box conveying line 8 are all drivingly connected to the output end of the driving mechanism. The input ends of the first speed-changing mechanism 15, the second speed-changing mechanism 16, and the third speed-changing mechanism 19 are all drivingly connected to the output end of the driving mechanism. The output end of the first speed-changing mechanism 15 is drivingly connected to the instruction manual folding machine 3. By adjusting the first speed-changing mechanism 15, the working speed of the instruction manual folding machine 3 can be adjusted. The output end of the second speed-changing mechanism 16 is drivingly connected to the box-taking and box-opening device 9. By adjusting the second speed-changing mechanism 16, the working speed of the box-taking and box-opening device 9 can be adjusted. The output end of the third speed-changing mechanism 19 is drivingly connected to the box-closing device 10. By adjusting the third speed-changing mechanism 19, the working speed of the box-closing device 10 can be adjusted. Thus, when the pitch of the bins on the product conveying line 2, the instruction manual conveying line 6, and the paper box conveying line 8 can be adjusted to change, only by adjusting the first speed-changing mechanism 15, the second speed-changing mechanism 16, and the third speed-changing mechanism 19 to make the working speeds of the instruction manual folding machine 3, the box-taking and box-opening device 9, and the box-closing device 10 match the changed bin pitch, the paper boxes 81 of corresponding sizes can be processed, enabling the entire system to work stably and greatly improving the compatibility of the cartoning machine with the sizes of the paper boxes 81. Moreover, the entire system is driven by a single power source of the driving member 11, and each module simultaneously drives the product conveying line 2, the instruction manual conveying line 6, the paper box conveying line 8, the instruction manual folding machine 3, the instruction manual pushing tray 4, the instruction manual triangular conveying line 5, the rotary pushing device 7, the box-taking and box-opening device 9, and the box-closing device 10 through the driving mechanism. Compared with using multiple power sources to drive different modules, the synchronization of each module during operation is better, with a low synchronization error, and thus the execution effect of the entire device is good. Specifically, in this embodiment, the first speed-changing mechanism 15, the second speed-changing mechanism 16, and the third speed-changing mechanism 19 can be existing gearboxes, and of course, they can also be other speed-changing mechanisms, as long as they can change the speed of the output-end module. The driving member 11 is a driving motor. The instruction manual folding machine 3, the box-taking and box-opening device 9, and the box-closing device 10 are all existing devices in the cartoning machine.

[0045] Specifically, the driving mechanism includes a total transmission assembly 12, a total reduction gearbox 13, a first transmission assembly 14, a second transmission assembly 17, and a third transmission assembly 18. The driving member 11 transmits power to the first transmission assembly 14, the second transmission assembly 17, and the third transmission assembly 18 through the total transmission assembly 12 and the total reduction gearbox 13. The output end of the driving member 11 is connected to the input end of the total transmission assembly 12, and the output end of the total transmission assembly 12 is drivingly connected to the input end of the total reduction gearbox 13. Among them, the input end of the first transmission assembly 14 is drivingly connected to the first output end of the total reduction gearbox 13. The first output end of the first transmission assembly 14 is drivingly connected to the instruction manual pusher 4, the second output end of the first transmission assembly 14 is drivingly connected to the instruction manual triangular conveyor line 5, and the third output end of the first transmission assembly 14 is drivingly connected to the input end of the first speed change mechanism 15. The total reduction gearbox 13 can drive the instruction manual pusher 4, the instruction manual triangular conveyor line 5, and the first speed change mechanism 15 to work simultaneously. The input end of the second speed change mechanism 16 is drivingly connected to the second output end of the total reduction gearbox 13, and the total reduction gearbox 13 directly drives the second speed change mechanism 16 to work. The input end of the second transmission assembly 17 is drivingly connected to the third output end of the total reduction gearbox 13 and is drivingly connected to the product conveyor line 2, the instruction manual conveyor line 6, and the rotary pusher device 7, so that the total reduction gearbox 13 drives the three to move simultaneously. The input end of the third transmission assembly 18 is drivingly connected to the output end of the second transmission assembly 17. The first output end of the third transmission assembly 18 is drivingly connected to the carton conveyor line 8, so that the total reduction gearbox 13 can drive the carton conveyor line 8 to move. The second output end of the third transmission assembly 18 is drivingly connected to the input end of the third speed change mechanism 19, and the total reduction gearbox 13 can drive the second speed change mechanism 16 to work. Thus, the driving member 11 can drive the product conveyor line 2, the instruction manual conveyor line 6, the carton conveyor line 8, the instruction manual paper folding machine 3, the instruction manual pusher 4, the instruction manual triangular conveyor line 5, the rotary pusher device 7, the box taking and opening device 9, and the box closing device 10 to move simultaneously through the total transmission assembly 12 and the total reduction gearbox 13, and the synchronization is better. In this embodiment, the total transmission assembly 12 can be a conveyor belt mechanism arranged front and back, and the total reduction gearbox 13 is an existing reduction box.

[0046] Further, as Figure 1As shown (where the description of the following positional relationships is determined according to the up, down, left, and right in the figure), the first transmission component 14 is located on the left side of the driving member 11, the second speed change mechanism 16 is located in front of the total reduction gearbox 13, the output end of the second transmission component 17 is located on the right side of the driving member 11, and the third speed change mechanism 19 is located on the right side of the second speed change mechanism 16. Correspondingly, the instruction paper folding machine 3, the instruction pushing tray 4, and the instruction triangular conveying line 5 connected to the output end of the first transmission component 14 are located on the left side of the driving member 11. At the same time, the instruction paper folding machine 3, the instruction pushing tray 4, and the instruction triangular conveying line 5 are located at the input end of the instruction 54 conveying line. The box taking and opening device 9 is located in front of the driving member 11. At the same time, the box taking and opening device 9 is located at the box inlet end of the paper box conveying line 8. The box closing device 10 is located on the right side of the driving member 11. At the same time, the box closing device 10 is located at the end of the paper box conveying line 8 at the box outlet, so that the arrangement positions of the driving member 11, the first transmission component 14, the second transmission component 17, and the third rotating component can be adapted to the positions of the corresponding driven motion modules, thereby making the entire motion module driving structure more reasonable and the driving structure setting simpler.

[0047] Specifically, the first transmission assembly 14 includes a first conveyor belt line 141, a first chain drive line 142, a second chain drive line 143, a first reduction gearbox 144, and a second reduction gearbox 145. The first conveyor belt line 141, the first chain drive line 142, and the second chain drive line 143 can be existing chain drive mechanisms, and the first reduction gearbox 144 and the second reduction gearbox 145 are existing reduction gearboxes. The first conveyor belt line 141 is vertically arranged and located on the left side of the total reduction gearbox 13, and the input end of the first conveyor belt line 141 is connected to the first output end of the total reduction gearbox 13. The second chain drive line 143, the first chain drive line 142, and the first conveyor belt line 141 are arranged from left to right. Both the first chain drive line 142 and the second chain drive line 143 are arranged in the front-rear direction, and the output end of the first chain drive line 142 is located behind the output end of the second chain drive line 143. The output end of the first conveyor belt line 141, the input end of the first chain drive line 142, and the input end of the second chain drive line 143 are coaxially connected. The output end of the second chain drive line 143, the input end of the first reduction gearbox 144, and the input end of the second reduction gearbox 145 are coaxially connected. The output end of the first reduction gearbox 144 is drivingly connected to the specification triangular conveyor line 5, and the output end of the second reduction gearbox 145 is drivingly connected to the specification pusher plate 4. The output end of the first chain drive line 142 is drivingly connected to the input end of the first speed change mechanism 15. Thus, the total reduction gearbox 13 drives the second chain drive line 143 and the first chain drive line 142 to move through the first conveyor belt line 141. The first chain drive line 142 drives the first speed change mechanism 15 to transmit power, so that the first speed change mechanism 15 drives the specification folding machine 3 to work. The second chain drive line 143 drives the first reduction gearbox 144 and the second reduction gearbox 145. The first reduction gearbox 144 drives the specification triangular conveyor line 5 to work, and at the same time, the second reduction gearbox 145 drives the specification pusher plate 4 to work.

[0048] Specifically, the second transmission assembly 17 includes a second conveyor belt line 171. The second conveyor belt line 171 is horizontally arranged in the left-right direction. The third output end of the total reduction gearbox 13 is arranged backward and connected to the input end of the second conveyor belt line 171. The output end of the second conveyor belt line 171 is located on the right side of the total reduction gearbox 13. The output end of the second conveyor belt line 171 is drivingly connected to a first transmission shaft 172 arranged forward. The first transmission shaft 172 is drivingly connected to the product conveyor line 2, the specification conveyor line 6, and the rotary pusher device 7. Thus, the total reduction gearbox 13 can drive the product conveyor line 2, the specification conveyor line 6, and the rotary pusher device 7 to rotate and work simultaneously through the second conveyor belt line 171.

[0049] Specifically, the third transmission assembly 18 includes a third conveyor belt line 181 and a fourth conveyor belt line 182, both of which are horizontally arranged in the left-right direction; the input end of the third conveyor belt line 181 is drivingly connected to the output end of the second conveyor belt line 171, the output end of the third conveyor belt line 181 is located on the right side of the second conveyor belt line 171, and is connected to a forwardly arranged second transmission shaft 183, the second transmission shaft 183 is drivingly connected to the carton conveying line 8, the input end of the fourth conveyor belt line 182 is connected to the second transmission shaft 183, the output end of the fourth conveyor belt line 182 is located on the left side of the second transmission shaft 183, and is drivingly connected to the input end of the third speed change mechanism 19. Thus, the total reduction gearbox 13 drives the third conveyor belt line 181 to drive through the second conveyor belt line 171, and drives the carton conveying line 8 to rotate and work simultaneously with the product conveying line 2 and the instruction manual conveying line 6, with the same conveying speed. At the same time, it drives the third speed change mechanism 19 to work, and the third speed change mechanism 19 drives the carton closing device 10 to work to perform carton closing treatment on the carton 81.

[0050] The cartoning machine further includes a product feeding mechanism 20, the product feeding mechanism 20 includes a feeding star wheel 201 and a transmission gear 202, the transmission gear 202 is coaxial with the input ends of the second chain transmission line 143 and the first chain transmission line 142, the transmission gear 202 and the feeding star wheel 201 are drivingly connected, and a corresponding product upstream conveying line 30 is provided at the feeding star wheel 201. The product 24 on the product upstream conveying line 30 is conveyed to the product conveying line 2 through the feeding star wheel 201. If the pitch of the bins on the product conveying line 2 changes, the corresponding feeding star wheel 201 also needs to be replaced so that the distance between two teeth on the feeding star wheel 201 adapts to the pitch of the bins on the product conveying line 2 to ensure the stable transportation of the product 24.

[0051] In summary, the driving member 11 drives the total reduction gearbox 13 to transmit power through the total transmission assembly 12, and the total reduction gearbox 13 works in three paths simultaneously. Among them, the first path drives the first chain transmission line 142 and the second chain transmission line 143 through the first conveyor belt line 141. The first chain transmission line 142 drives the instruction paper folding machine 3 to work through the first speed change mechanism 15, and the second chain transmission line 143 drives the instruction material pushing tray 4 and the instruction triangular conveying line 5 to work. The second path directly drives the second speed change mechanism 16 to transmit power, and the second speed change mechanism 16 drives the box taking and opening device 9 to work. The third path drives the third conveyor belt line 181 through the second conveyor belt line 171. At the same time, the output end of the second conveyor belt line 171 drives the product conveying line 2, the instruction triangular conveying line 5 and the rotary material pushing device 7 to work simultaneously. The third conveyor belt line 181 drives the fourth conveyor belt line 182, and at the same time, the output end of the third conveyor belt line 181 drives the paper box conveying line 8 to work. The fourth conveyor belt line 182 drives the third speed change mechanism 19 to work, and the third speed change mechanism 19 drives the box closing device 10 to work. Therefore, the driving member 11 can drive the product conveying line 2, the instruction conveying line 6, the rotary material pushing device 7, the instruction paper folding machine 3, the instruction material pushing tray 4, the instruction triangular conveying line 5, the paper box conveying line 8, the box taking and opening device 9 and the box closing device 10 to work simultaneously, and the working synchronization is better.

[0052] Specifically, in order to adjust the bin pitch on the product conveying line 2, in this embodiment, as Figure 3-4 shown, the product conveying line 2 includes a first chain drive assembly 21 and a plurality of first bin mounting plates 22 arranged at intervals and mounted on the first chain drive assembly 21. Among them, the first chain drive assembly 21 is an existing conveying device, and a first bin 23 is detachably mounted on the first bin mounting plate 22. When it is necessary to adjust the bin pitch, only the first bin 23 on the first bin mounting plate 22 needs to be disassembled or installed, so that the distance between two adjacent first bins 23 changes, that is, the corresponding bin pitch also changes. The user can adjust it to the corresponding size according to the required bin pitch size. Moreover, the first bin 23 is mounted on the first bin mounting plate 22 by bolts, so the first bin 23 is also relatively convenient to disassemble and install.

[0053] Specifically, the adjustment principle of the bin pitch on the instruction manual conveyor line 6 and the carton conveyor line 8 is the same as that on the product conveyor line 2. Among them, the instruction manual conveyor line 6 includes a second chain drive assembly and a plurality of second bin mounting plates arranged at intervals and mounted on the second chain drive assembly. The second chain drive assembly is an existing device, and a second bin is provided on the second bin mounting plate. When the bin pitch needs to be adjusted, only the second bin on the second bin mounting plate needs to be disassembled or installed to meet the required size of the user; correspondingly, the carton conveyor line 8 includes a third chain drive assembly and a plurality of third bin mounting plates arranged at intervals and mounted on the third chain drive assembly. The third chain drive assembly is an existing conveyor device, and a third bin is provided on the third bin mounting plate. When the bin pitch needs to be adjusted, only the third bin on the third bin mounting plate needs to be disassembled or installed to meet the required size of the user; the structures of the first bin mounting plate 22, the second bin mounting plate, and the third bin mounting plate can be the same, but the sizes need to be adapted to the corresponding chain drive assemblies. The structures of the first bin 23, the second bin, and the third bin are the same, but the sizes need to be adapted to the corresponding chain drive assemblies. Moreover, the adjusted bin pitches on the product conveyor line 2, the instruction manual conveyor line 6, and the carton conveyor line 8 are the same.

[0054] Specifically, in order for the instruction manual triangular conveyor line 5 to adjust the distance between the chucks 53 thereon, in this embodiment, as Figure 5As shown, the instruction manual triangular conveyor line 5 includes an instruction manual triangular conveyor line assembly 51 and a plurality of chuck mounting plates 52 installed at intervals on the instruction manual triangular conveyor line assembly 51. Among them, the instruction manual triangular conveyor line assembly 51 is an existing conveyor device, and a chuck 53 is detachably mounted on the chuck mounting plate 52. When it is necessary to adjust the distance between two adjacent chucks 53, it is only necessary to disassemble or install the chuck 53 so that the distance between the two chucks 53 meets the requirements of the user. Moreover, the chuck 53 is installed on the instruction manual triangular conveyor line assembly 51 by screws, and the disassembly is also relatively convenient. The chuck 53 is an existing chuck 53 for clamping the instruction manual 54. Thus, when the user is dealing with another type of paper box 81, after adjusting the bin pitch on the product conveyor line 2, the instruction manual conveyor line 6, and the paper box conveyor line 8, the user only needs to appropriately adjust the distance between two adjacent chucks 53 on the instruction manual triangular conveyor line assembly 51 according to the adjusted bin pitch, so that the distance between the two chucks 53 adapts to the adjusted bin pitch, that is, the distance between two instruction manuals 54 transported on the instruction manual triangular conveyor line assembly 51 adapts to the adjusted bin pitch, enabling the instruction manual 54 to be stably placed in the bin on the instruction manual conveyor line 6 and stably placed in the paper box 81. Specifically, the rotary pusher device 7 is an existing device, and the push rods 71 installed thereon are all detachable. When adjusting the distance between two adjacent push rods 71, it is only necessary to disassemble or install the corresponding number of push rods 71 so that the distance between two adjacent push rods 71 adapts to the changed bin pitch. Among them, as Figure 2 shown, H4 is the distance between two push rods 71.
