Description

Technical Field

[0001] This invention relates to the field of cardboard box bundling technology, and in particular to an automatic corner protection mechanism for cardboard box bundling. Background Technology

[0002] Cardboard box strapping machines are generally used in conjunction with production lines. They typically use PP strapping to strap cardboard boxes, then tighten them and join the ends using a heat-sealing head. They are suitable for packing goods of various sizes, such as books, magazines, cardboard boxes, postal parcels, and other items.

[0003] However, existing strapping machines for cardboard boxes have certain drawbacks. During transportation, the unpredictable position and angle of the boxes can affect the tightness of the strapping and even cause the edges of the boxes to tear. To solve this problem, people usually manually insert paper cards into the strapping area to avoid direct contact between the PP strapping and the cardboard / packing material. The paper cards act as a protective edge banding material between the PP strapping and the packaged item. In other words, this manual insertion of paper cards reduces efficiency, increases labor costs, and poses safety hazards, thus necessitating an improvement. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the first objective of the present invention is to provide a paper card bending device that realizes automatic bending of paper cards, and has a clever and simple structure, is automatic and convenient, and is safe to operate.

[0005] The above-mentioned technical objective of this invention is achieved through the following technical solution: a paper card bending device, comprising a bracket, an adsorption belt box for adsorbing and conveying paper cards, and a bending assembly arranged along the conveying direction of the adsorption belt box, the bending assembly having a torsion section and being used to abut against one side of the paper card; the paper card, under the cooperative conveying of the bending assembly and the adsorption belt box, has at least a first position parallel to the adsorption side of the adsorption belt box and a second position perpendicular to the adsorption side of the adsorption belt box. By driving the paper card through the adsorption belt box and cooperating with the torsion of the bending assembly, the end of the paper card is automatically bent from its original 180° to 90°. The overall structure is simple, automatic and convenient, and safe to operate.

[0006] In a further embodiment of the present invention, the chuck assembly includes a plurality of rolling wheels and a chuck mounted on the plurality of rolling wheels, wherein the torsion section is disposed on the chuck.

[0007] In a further embodiment of the present invention, the shank assembly is a shank plate, the shank plate is made of a rigid material, and the torsion section is disposed on the shank plate.

[0008] In a further embodiment of the present invention, the adsorption belt box includes: a vacuum chamber, a conveyor belt with adsorption holes, an adsorption fan, and a servo motor; the air inlet of the adsorption fan is sequentially connected to the vacuum chamber and the adsorption holes, and the air outlet is connected to the outside. The paper card is adsorbed onto the conveyor belt by vacuum adsorption. The paper card is fixed by adsorption through the adsorption fan, and the conveyor belt is driven by the servo motor to achieve stable conveying of the paper card.

[0009] In a further embodiment of the present invention, the adsorption belt box is mounted on the bracket; the adsorption belt boxes are arranged in pairs, with the two adsorption belt boxes positioned vertically and the spacing between them adjustable. This allows the spacing between the two adsorption belt boxes to be adjusted according to different sizes of paper cards, ensuring the adsorption stability of the paper cards and improving overall applicability.

[0010] The second objective of this invention is to provide an automatic corner protector mechanism for cardboard box bundling, which enables automatic feeding and bending of paper cards, and precise cutting into the bundling station of the cardboard box, with a high degree of automation and relatively high production efficiency.

[0011] The above-mentioned technical objective of this invention is achieved through the following technical solution: an automatic corner protection mechanism for carton strapping, comprising a frame, a lower belt conveyor mounted on the frame, paper card bending devices respectively disposed on both sides of the lower belt conveyor as described above; a paper card feeding device and a paper card feeding tracking device mounted on the support; and a controller; the carton is input from one end of the lower belt conveyor and output to the carton strapping machine from the other end after corner protection operation by the paper card bending device; when the paper card feeding tracking device detects that the carton has been conveyed to the target position of the lower belt conveyor, the controller controls the paper card feeding tracking device to transfer the paper card to the suction belt box, and the suction belt box conveys the paper card to the strapping station at the edge of the carton to be strapped. In this mechanism, the feeding, feeding, and bending of the paper cards are all automated. The paper card feeding tracking device detects the position of the carton, thereby synchronously and accurately cutting the paper card to the strapping station at the edge of the carton to be strapped, which helps to reduce safety hazards and greatly improve production efficiency.

[0012] In a further embodiment of the present invention, the paper feeding device includes a paper roll mounted on the frame, several guide rollers, a paper roll feeding motor electrically connected to the controller, and a paper cutting device mounted on the frame. The paper roll feeding motor feeds the paper in an orderly manner according to the controller's instructions, cutting the paper strip.

[0013] In a further embodiment of the present invention, the paper cutting device includes: a paper cutting blade holder and a paper cutting cylinder; the controller controls the paper cutting cylinder to cut the paper strip into paper cards of the target length according to preset parameters.

[0014] In a further embodiment of the present invention, the paper card feeding and tracking device includes: a second photoelectric switch, and a feeding cylinder disposed on one side of the paper cutting device; the feeding cylinder is used to pick up the paper card after the paper cutting device has completed cutting, and to transfer the paper card to the adsorption belt box when the second photoelectric switch detects a carton signal.

[0015] A further provision of the present invention includes a digital printer mounted on the bracket, the digital printer being located at the front end of the paper cutting device, and the printing information of the digital printer including one or more of the following: product specifications, production date and batch number, product material, QR code, barcode, logo pattern, and customer name.

[0016] In a further embodiment of the invention, the frame is equipped with an adjusting slide rail, which is perpendicular to the conveying direction of the lower belt conveyor. The supports on both sides are slidably mounted on the adjusting slide rail. Therefore, during use, the spacing of the paper card bending devices on both sides can be adjusted according to different carton specifications by adjusting the spacing of the supports, ensuring that the paper cards can be accurately cut into the binding station at the edge of the carton to be bound, thereby improving the practicality of the equipment.

[0017] A further feature of the invention includes an upper pressure paper conveyor belt positioned above the lower conveyor belt, the upper pressure paper conveyor belt moving synchronously with the lower conveyor belt. This allows for vertical positioning of the cartons, preventing displacement during transport and bundling.

[0018] In summary, the present invention has the following beneficial effects: 1. The paper card bending device of the present invention drives the paper card to run by an adsorption belt box and simultaneously rotates the crooked belt component, so that the end of the paper card is automatically bent from the original 180° to 90°. It can effectively solve the problem of manual bending of paper cards in the prior art, and the structure is ingenious and simple, and the operation is efficient and convenient.

[0019] 2. The automatic corner protector mechanism for cardboard box bundling in this invention automates the entire process of cardboard card feeding, feeding, and bending. A cardboard card feeding tracking device detects the position of the cardboard box and simultaneously transfers the cardboard card to the suction conveyor belt, precisely cutting it into the bundling station at the edge of the cardboard box to be bundled. Compared to the existing technology of manually bending and inserting the cardboard card into the bundling area, this significantly increases production efficiency and improves operational safety. Furthermore, it strengthens the bundling at the edge of the cardboard box, enhancing the protection of the cardboard box and the contents inside. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0024] Example 1: This example relates to a paper card bending device, such as... Figure 1 , Figure 2 and Figure 4As shown, the assembly includes a support 03, an adsorption belt box 32, and a conveyor belt assembly 31. The adsorption belt box 32 is used to adsorb and transport paper cards 05. The conveyor belt assembly 31 is arranged along the transport direction of the adsorption belt box 32 and includes a plurality of rolling wheels 311 and a conveyor belt 312 mounted on the rolling wheels 311. The conveyor belt 312 has a torsion section and is used to abut against one side of the paper card 05. Driven by a rolling motor 313, the conveyor belt 312 runs around the rolling wheels 311, thereby bending the paper card 05 along its torsion direction. Under the cooperative transport of the conveyor belt 312 and the adsorption belt box 32, the paper card 05 has at least a first position parallel to the adsorption side of the adsorption belt box 32 and a second position perpendicular to the adsorption side of the adsorption belt box 32.

[0025] Compared to the existing technology that uses manual bending or robotic bending, this embodiment uses the adsorption belt box 32 to drive the paper card 05 while coordinating the "twisted" twist of the crook assembly 31, so that the end of the paper card 05 is automatically bent from the original 180° to 90°. The structure is ingenious and simple, automatic and convenient, and the operation is very safe.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the adsorption belt box 32 includes: a vacuum chamber 321, a conveyor belt 322 with adsorption holes, an adsorption fan, and a servo motor (not shown). The conveyor belt 322 is mounted on the edge of the vacuum chamber 321 and runs along the conveying direction of the paper card 05 under the drive of the servo motor. The air inlet of the adsorption fan is connected to the vacuum chamber 321 and the adsorption holes in sequence, and the air outlet is connected to the outside. On the one hand, the paper card 05 is adsorbed onto the conveyor belt 322 by the adsorption fan; on the other hand, the paper card 05 is driven by the conveyor belt 322 under the action of the servo motor, thereby achieving stable conveying of the paper card 05.

[0027] like Figure 2As shown, the adsorption belt box 32 is mounted on the bracket 03, and the conveyor belt assembly 31 is mounted on the adsorption belt box 32. In this embodiment, the adsorption belt boxes 32 are arranged in pairs, with the two adsorption belt boxes 32 arranged vertically and the spacing between them is adjustable. The lower adsorption belt box 32 is fixedly mounted on the bracket 03, and the upper adsorption belt box 32 is slidably mounted on the bracket 03 via a sub-bracket 04. The bracket 03 is provided with a guide rail 031 for sliding cooperation with the sub-bracket 04. The bracket 03 is also equipped with a first motor 032, and the output end of the first motor 032 is provided with a first lead screw 033. The sub-bracket 04 is provided with a first slider 034 that is threadedly engaged with the first lead screw 033. Thus, the first motor 032 drives the first slider 034 to move the sub-bracket 04 and the upper adsorption belt box 32 up and down. In other embodiments, the distance between the two adsorption belt boxes 32 can be manually adjusted according to the length of the paper card 05 by locking the sub-support 04 into the waist-shaped groove on the support 03, thereby ensuring that the two adsorption belt boxes 32 can stably adsorb the paper card 05 and improving the overall applicability.

[0028] In this embodiment, combined with Figure 1 and Figure 2 As shown, the adsorption belt boxes 32 are arranged in pairs, one above the other. Similarly, there are two bending belt components 31, each mounted on a side of the two adsorption belt boxes 32 that are far apart from each other. This allows for bending of both ends of the paper card 05. When the height of the upper adsorption belt box 32 is adjusted, the upper bending belt component 31 is also adjusted accordingly. In other embodiments, the selection can be made according to actual needs. When the paper card 05 is long and only one end needs to be bent, two adsorption belt boxes 32 and one bending belt component 31 are used together. When the paper card 05 is short and both ends need to be bent, one adsorption belt box 32 and two bending belt components 31 are used together.

[0029] Example 2: This example relates to a paper card bending device, such as... Figure 6 As shown, the device includes a support 03, an adsorption belt box 32, and a bending assembly 31. The adsorption belt box 32 is used to adsorb and transport paper cards 05. The bending assembly 31 is arranged along the transport direction of the adsorption belt box 32. Unlike Embodiment 1, the bending assembly 31 is a bending plate 314 made of a rigid material, such as stainless steel, iron, or aluminum alloy. The torsion section is located on the bending plate 314. Furthermore, the bending plate 314 is equipped with several rollers 315 to reduce friction between the bending plate 314 and the paper cards 05, ensuring that the paper cards 05 can bend smoothly along the adsorption belt box 32 and the bending plate 314. The overall structure is simple, requires no additional driving force, and is safe to operate.

[0030] Furthermore, this embodiment also relates to an automatic corner protection mechanism for cardboard box bundling, such as... Figure 3-5 As shown, the machine includes a frame 01, a lower belt conveyor 02, paper card bending devices 3 respectively disposed on both sides of the lower belt conveyor 02 as described above; a paper card feeding device 5 and a paper card feeding tracking device 4 mounted on the support 03; and a controller. The lower belt conveyor 02 is used to transport cartons 00 to be bundled. The cartons 00 are input from one end of the lower belt conveyor 02, and after passing through the corner protection operation of the paper card bending device 3, they are output from the other end to the carton 00 bundling machine.

[0031] When the paper card feeding and tracking device 4 detects that the carton 00 has been conveyed to the target position on the lower belt conveyor 02, the controller controls the paper card feeding and tracking device 4 to transfer the paper card 05 to the adsorption belt box 32, and then the adsorption belt box 32 conveys the paper card 05 to the binding station at the edge of the carton 00 to be bound. In this mechanism, the feeding, dispensing, and bending of the paper card 05 are all automated. The paper card feeding and tracking device 4 detects the position of the carton 00, thereby simultaneously and accurately cutting the paper card 05 to the binding station at the edge of the carton 00 to be bound, effectively improving production efficiency and reducing safety hazards.

[0032] like Figure 3 As shown, the paper feeding device 5 includes a paper roll 51 mounted below the frame 01, several guide rollers 52, a paper roll feeding motor (not shown) electrically connected to the controller, and a paper cutting device 53. The paper roll feeding motor feeds paper in an orderly manner according to the controller's instructions. Figure 4 and Figure 5 As shown, the paper cutting device 53 includes: a paper cutting blade holder 531 and a paper cutting cylinder 532; the controller controls the paper cutting cylinder 532 to cut the paper strip into paper cards 05 of the target length according to preset parameters.

[0033] In this mechanism, a first photoelectric switch (not shown) is installed at the entrance end of the lower conveyor belt 02. When the first photoelectric switch detects the presence of a carton 00 signal, the controller activates the automatic corner protection mechanism for carton bundling. The paper card feeding and tracking device 4 includes a second photoelectric switch 41 and a feeding cylinder 42. The second photoelectric switch 41 is located on the side of the bracket 03 near the paper cutting device 53 and is used to detect the target position in front of the carton bundling station. The feeding cylinder 42 picks up the paper card 05 at the paper cutting station by air adsorption and transfers the paper card 05 to the adsorption belt box 32. When the second photoelectric switch 41 detects a carton signal, the controller controls the feeding cylinder 42 to transfer the adsorbed paper card 05 to the adsorption belt box 32. Under the action of the servo motor of the adsorption belt box 32, the paper card 05 adsorbed by the adsorption belt box 32 is precisely cut into the bundling station at the edge of the carton to be bundled.

[0034] like Figure 3 As shown, in this embodiment, the automatic corner protector mechanism for carton bundling also includes a digital printer 7 mounted on the bracket 03. The digital printer 7 is located at the front end of the paper cutting device 53 and is used to print relevant information on the paper tape. The printing information of the digital printer 7 includes one or more of the following: product specifications, production date and batch, product material, QR code, barcode, logo pattern, and customer name.

[0035] To further improve the versatility of this automatic corner protection mechanism for cardboard box bundling, such as... Figure 3 As shown, the frame 01 is equipped with an adjusting slide rail 8, which is perpendicular to the conveying direction of the lower belt conveyor 02. The supports 03 on both sides are slidably mounted on the adjusting slide rail 8. The frame 01 is equipped with a second motor 81 and a second lead screw 82 mounted on the output shaft of the second motor 81. The supports 03 on both sides are equipped with second sliders 83 threaded onto the second lead screw 82, thereby driving the supports 03 to move closer to or further away from the adjusting slide rail 8 via the second motor 81. Since the paper card bending device 3, the paper card feeding device 5, and the paper card feeding tracking device 4 are all mounted on the supports 03, the spacing of the paper card bending devices on both sides can be adjusted by adjusting the spacing of the supports 03 on both sides. Therefore, during use, the spacing of the paper card bending devices 3 on both sides can be adjusted according to different carton 00 specifications to ensure that the paper card 05 can be accurately cut into the binding station at the edge of the carton to be bound, thereby improving the practicality of the equipment.

[0036] Furthermore, the frame 01 is also equipped with an upper pressure paper belt (not shown) above the lower belt conveyor 02, which moves synchronously with the lower belt conveyor 02. This can limit the position of the carton 00 in the upper and lower positions, preventing the carton 00 from shifting during the conveying and bundling process.

[0037] During operation, when the first photoelectric switch detects a carton signal, the automatic corner protection mechanism for carton bundling starts. According to preset parameters, the controller controls the paper roll feeding motor to feed at a preset speed. The paper strip runs with several guide rollers 52, passing the digital printer 7 along the way, where the digital printer 7 prints relevant batch information. Then it runs to the paper cutting device 53, where the controller controls the paper cutting cylinder 532 to cut the printed paper strip into paper cards 05 according to a preset length. The cut paper cards 05 are picked up by the feeding cylinder 42. When the second photoelectric switch 41 detects a carton signal, the controller controls the feeding cylinder 42 to transfer the paper cards 05 to the suction belt box 32. At the same time, under the action of the servo motor of the suction belt box 32, the paper cards 05 adsorbed by the suction belt box 32 are precisely cut into the bundling station at the edge of the carton to be bundled. At this time, the adsorption belt box 32 and the swivel assembly 31 are running synchronously with the lower belt conveyor 02. The adsorption belt box 32 drives the paper card 05 to run, and at the same time, the swivel assembly 31 twists in a "twisted" shape, so that the end of the paper card 05 is bent from the original 180° to 90° along the twisting direction of the swivel 312. The structure is ingenious and simple, automatic and convenient, and the operation is very safe.

[0038] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
