Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, and in particular to a material edge protection and binding device. Background Technology

[0002] Currently, in modern industrial production and logistics transportation, the bundling and packaging of rectangular items (such as various packaging boxes, boards, etc.) is a key link in ensuring the safe transportation and storage of products. Traditional methods of bundling rectangular items mainly focus on using materials such as ropes, tapes, or plastic strips to wrap the items horizontally or vertically, thereby enhancing the structural stability of the items during handling and stacking, and preventing the items from scattering or being damaged. For example, a circular wrapping machine for logistics packaging disclosed in Chinese Patent Publication No. CN118753568A includes a base and a ring-shaped material. The inner wall of the base is symmetrically rotatably connected to a rotating shaft and a rotating rod. Friction wheels and transmission wheels are fixedly and offset on the side walls of the rotating rod and the rotating rod. The four friction wheels are slidably connected to a ring-shaped winding component. A winding roller is provided on the ring-shaped winding component. A synchronous belt is connected to two adjacent transmission wheels. A fixing plate is fixed to the side wall of the base. A motor is installed on the side wall of the fixing plate. A transmission rod is fixed to the output end of the motor. A guide roller is fixed to the side wall of the transmission rod. A processing mechanism for processing the ring-shaped material is fixed to the side wall of the base.

[0003] However, in practical applications, especially when the corners of rectangular items are relatively fragile, conventional wrapping methods can compress and damage the corners of rectangular items, which may in turn damage the products inside the packaging, leading to economic losses. Utility Model Content

[0004] Therefore, in response to the above problems, this utility model proposes a material edge protection and binding device, which solves the technical problem that the edges and corners of rectangular items are easily damaged when they are wrapped in a ring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a material edge protection and binding device, comprising a frame and a material conveying mechanism for conveying rectangular items on the frame, and an annular binding mechanism located behind the material conveying mechanism. A placing mechanism for placing edge protection plates is provided on the side of the frame in the direction of conveying the rectangular items. The placing mechanism includes an edge protection input mechanism, a transfer mechanism for transferring the edge protection plates from the edge protection input mechanism to the side of the rectangular items, and a fixing mechanism for fixing the edge protection plates to the side of the rectangular items.

[0006] Furthermore, the transfer mechanism includes a rotary conveying mechanism and multiple adsorption mechanisms, wherein the multiple adsorption mechanisms are spaced apart on the rotary conveying mechanism to achieve cyclic conveying.

[0007] Furthermore, the adsorption mechanism includes an adsorption seat on a rotary conveying mechanism and a suction nozzle on the adsorption seat, with each suction nozzle connected to an external pneumatic mechanism to achieve negative pressure adsorption.

[0008] Furthermore, a multi-channel rotary joint is provided on the frame, and each suction nozzle is connected to an external pneumatic mechanism through the multi-channel rotary joint.

[0009] Furthermore, the edge protector is a flexible plate, and the edge protector input mechanism includes an unwinding roller for storing continuous edge protectors, multiple guide rollers for guiding continuous edge protectors, a clamping and conveying mechanism for conveying continuous edge protectors, and an input fixing plate for adsorbing and fixing the edge protectors. A cutting mechanism for cutting the continuous edge protectors is provided between the clamping and conveying mechanism and the input fixing plate. An input plate cylinder is provided on the frame, and the input fixing plate is located on the piston rod of the input plate cylinder. The edge protector is in the cutting position when it is cut. The input plate cylinder pushes the input fixing plate from the cutting position to one of the adsorption mechanisms to realize the transfer of the edge protector.

[0010] Furthermore, the cutting mechanism includes a sub-blade mounted on the frame, a push cylinder mounted on the frame, and a mother blade mounted on the piston rod of the push cylinder. The push cylinder pushes the mother blade to cooperate with the sub-blade to achieve shearing.

[0011] Furthermore, a guide mechanism is provided between the clamping and conveying mechanism and the cutting mechanism to guide and maintain the position of the edge guard plate. The guide mechanism consists of two clamping plates that are close to each other, and a guide inclined surface is provided at the end of the clamping and conveying mechanism.

[0012] Furthermore, the clamping and conveying mechanism includes an active roller rotatably mounted on the frame, a clamping servo motor that drives the active roller, and a driven roller that cooperates with the active roller for clamping. The driven roller is mounted on an elastic tensioning mechanism.

[0013] Furthermore, the fixing mechanism is a synchronous belt mechanism located on the side of a rectangular item on the frame, and the synchronous belt mechanism is used to clamp the edge guard plate on the side of the rectangular item.

[0014] Furthermore, a bending mechanism for bending the edge guard plate is provided on the frame above and / or below the fixing mechanism, and the bending mechanism is a folding conveyor belt.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] 1. This material edge protection and binding device positions the placement mechanism on the side of the rectangular item conveying direction on the frame, cooperating with the material conveying mechanism and the ring binding mechanism. During the conveying of rectangular items, the placement and binding of the edge protection plate can be completed simultaneously, realizing an integrated process of edge protection and binding. This effectively improves production efficiency, reduces manual intervention, lowers labor intensity, and ensures the quality stability of the edge protection binding, avoiding problems such as inaccurate edge protection or weak binding caused by differences in manual operation. Therefore, it effectively protects the edges and corners of rectangular items, maintaining the integrity of the rectangular items' appearance, and thus effectively reducing the probability of damage to the packaged items.

[0017] 2. The transfer mechanism employs a rotary conveyor and multiple spaced adsorption mechanisms to achieve cyclical transport, making the transfer process of the edge protector more continuous and efficient. Multiple adsorption mechanisms can simultaneously perform edge protector transfer operations at different stages. For example, while one adsorption mechanism is adsorbing an edge protector, another adsorption mechanism can transfer the adsorbed edge protector to the side of a rectangular item, improving the overall operating efficiency of the equipment and shortening the production cycle.

[0018] 3. The adsorption mechanism achieves negative pressure adsorption through a combination of adsorption seats and nozzles, with each nozzle connected to an external pneumatic mechanism. This structure is simple and reliable, and can stably adsorb the edge protection panel. The negative pressure adsorption method minimizes damage to the edge protection panel, and the adsorption force can be adjusted according to actual needs through the pneumatic mechanism, ensuring the accuracy and reliability of adsorption.

[0019] 4. A multi-channel rotary joint is installed on the frame, allowing each suction nozzle to connect to an external pneumatic mechanism. This solves the problem of tangled wiring between the suction nozzles and the pneumatic mechanism during rotation of the rotary conveyor. The multi-channel design can provide a stable air pressure supply to multiple suction nozzles simultaneously, ensuring that each nozzle can work normally, improving the reliability and stability of the equipment, and reducing production interruptions caused by wiring failures.

[0020] 5. The edge-protecting input mechanism uses unwinding rollers to store continuous edge-protecting sheets. Through the cooperation of guide rollers, a clamping conveyor mechanism, and an input fixing plate, it achieves automatic conveying and positioning of the edge-protecting sheets. This design can accommodate edge-protecting sheets of different lengths and widths, improving the equipment's versatility. The cutting mechanism allows for precise cutting of the edge-protecting sheets according to actual needs, meeting the edge-protecting requirements of rectangular items of different sizes. An input plate cylinder pushes the input fixing plate to transfer the cut edge-protecting sheets to the adsorption mechanism, realizing an automated process from input to transfer, improving production efficiency and the transfer accuracy of the edge-protecting sheets.

[0021] 6. The cutting mechanism uses a combination of a female and a male blade. A cylinder drives the female and male blades to perform the cutting. This cutting method is simple in structure, easy to operate, and can quickly and accurately cut the edge guard plate. This cutting method produces a smoother cut on the edge guard plate, reducing burrs and deformation.

[0022] 7. The guiding mechanism, positioned between the clamping and conveying mechanism and the cutting mechanism, plays a crucial guiding and positioning role. Two closely spaced clamping plates ensure the edge guard plate maintains its correct position during conveying, preventing it from shifting or wobbling, thus guaranteeing cutting accuracy. The guide inclined surface near the clamping and conveying mechanism facilitates the smooth entry of the edge guard plate between the clamping plates, reducing jamming when entering the guiding mechanism and improving the smoothness of equipment operation.

[0023] 8. The clamping and conveying mechanism employs a combination of a driving roller, a clamping servo motor, and a driven roller. The driving roller is driven by the clamping servo motor, which works in conjunction with the driven roller to clamp and convey the edge protector. This design allows for precise control of the conveying speed and position of the edge protector, ensuring the stability and accuracy of the conveying process. The driven roller is mounted on an elastic tensioning mechanism, which automatically adjusts its position according to the thickness and tension of the edge protector, ensuring appropriate clamping force and preventing damage to the edge protector due to excessive clamping or slippage due to excessive clamping.

[0024] 9. The fixing mechanism uses a synchronous belt to clamp the edge guard plate onto the side of the rectangular item. The synchronous belt mechanism features smooth operation and uniform clamping force, firmly fixing the edge guard plate to the side of the rectangular item and preventing it from falling off during subsequent transportation or handling. At the same time, the synchronous belt mechanism has a relatively simple structure, is easy to maintain and service, and reduces the operating cost of the equipment.

[0025] 10. A bending mechanism, which is a folding conveyor belt, is installed above and / or below the synchronous belt mechanism. This design allows for bending of the edge guards according to actual needs, enabling them to better conform to the corners of rectangular items and improving edge protection. The folding conveyor belt can smoothly bend the edge guards, avoiding damage or deformation during the bending process. Furthermore, the bending angle and position can be adjusted according to rectangular items of different shapes and sizes, enhancing the adaptability and flexibility of the equipment.

Detailed Implementation

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0034] refer to Figures 1 to 5 This embodiment provides a material edge protection and binding device, including a frame 1 and a material conveying mechanism 2 for conveying rectangular items on the frame 1, and an annular binding mechanism 3 located behind the material conveying mechanism 2. The frame 1 is provided with a feeding mechanism for feeding edge protection plates 9 on the side located in the direction of conveying rectangular items. The feeding mechanism includes an edge protection input mechanism 4, a transfer mechanism 5 for transferring the edge protection plates 9 from the edge protection input mechanism 4 to the side of the rectangular items, and a fixing mechanism 6 for fixing the edge protection plates 9 to the side of the rectangular items.

[0035] The material conveying mechanism 2 can be a flat belt mechanism or a synchronous belt mechanism, or other flexible material conveying mechanism 2. It can be spaced apart on the frame 1 and located below the rectangular items. Furthermore, one or more mechanisms can be added above the rectangular items to form a clamping conveyor. Figure 1 As shown, this solution sets one clamping and conveying mechanism above the rectangular item and two below it, thus forming a clamping and conveying system. Of course, other different configurations are also possible. The ring-shaped binding mechanism 3 is a conventional device in the art, used to wrap and bind items using straps or ropes.

[0036] The transfer mechanism 5 includes a rotary conveyor 51 and multiple adsorption mechanisms, which are spaced apart on the rotary conveyor 51 to achieve cyclic conveying. The rotary conveyor 51 can be a conventional synchronous belt material conveyor 2, chain material conveyor 2, etc.

[0037] The adsorption mechanism includes an adsorption seat 521 mounted on a rotary conveyor 51 and a suction nozzle 522 mounted on the adsorption seat 521. Each suction nozzle 522 is connected to an external pneumatic mechanism to achieve negative pressure adsorption. A multi-channel rotary joint 53 is provided on the frame 1, and each suction nozzle 522 is connected to an external pneumatic mechanism through the multi-channel rotary joint 53. The suction nozzle 522 is a conventional flexible suction nozzle, and the multi-channel rotary joint 53 is a commercially available accessory.

[0038] The edge protector 9 is a flexible board, such as a plastic board, honeycomb cardboard, or foam board. Figure 3 As shown by the pink double-dotted line, the edge protection input mechanism 4 includes an unwinding roller 41 for storing continuous edge protection plates 9, multiple guide rollers 42 for guiding continuous edge protection plates 9, a clamping and conveying mechanism 43 for conveying continuous edge protection plates 9, and an input fixing plate 44 for adsorbing and fixing the edge protection plates 9. A cutting mechanism 45 for cutting the continuous edge protection plates 9 is provided between the clamping and conveying mechanism 43 and the input fixing plate 44. An input plate cylinder 46 is provided on the frame 1, and the input fixing plate 44 is provided on the piston rod of the input plate cylinder 46. The edge protection plate 9 is in the cutting position when it is cut. The input plate cylinder 46 pushes the input fixing plate 44 from the cutting position to one of the adsorption mechanisms to realize the transfer of the edge protection plate 9.

[0039] The input fixing plate 44 is provided with adsorption holes 441, and is connected to an external negative pressure device through the adsorption holes 441 to achieve negative pressure adsorption. The unwinding roller 41, guide roller 42, and input plate cylinder 46 are conventional structures in this field. Figure 4 In the middle, the input plate cylinder 46 is in the extended state, which causes the input fixing plate 44 to be transferred against the adsorption mechanism.

[0040] The cutting mechanism 45 includes a daughter blade 451 mounted on the frame 1, a push cylinder 452 mounted on the frame 1, and a mother blade 453 mounted on the piston rod of the push cylinder 452. The push cylinder 452 pushes the mother blade 453 to cooperate with the daughter blade 451 to achieve shearing. The cutting mechanism 45 can also adopt other cutting methods, such as using a cutting roller for roller cutting, using a scissor mechanism for shearing, or using a sliding seat to drive the cutting blade for cutting. The push cylinder 452 is a conventional structure in the art.

[0041] A guide mechanism is provided between the clamping and conveying mechanism 43 and the cutting mechanism 45 to guide and maintain the position of the edge guard plate 9. The guide mechanism consists of two close-to-each-other clamping plates 47, and a guide inclined surface 471 is provided at the end of the clamping and conveying mechanism 43 of each clamping plate. The guide mechanism can also adopt other structures, such as using only one inclined surface for guidance, as long as the edge guard plate 9 can be stably entered into the cutting mechanism.

[0042] The clamping and conveying mechanism 43 includes a drive roller 431 rotatably mounted on the frame 1, a clamping servo motor (not shown in the figure) driving the drive roller 431, and a driven roller 432 that cooperates with the drive roller 431 for clamping. The driven roller 432 is mounted on an elastic tensioning mechanism 433. The elastic tensioning mechanism 433 is a conventional mechanism in the art, and its purpose is to ensure that the driven roller 432 always abuts against the drive roller 431 to achieve effective clamping. The clamping and conveying mechanism 43 can also use a clamping conveyor belt, the main purpose of which is to stably convey the edge guard plate 9 and to pause at any position for easy cutting.

[0043] During the conveying process of the edge guard plate 9, an active tensioning mechanism is provided. This active tensioning mechanism includes a slide rail 481 mounted on the frame 1, a sliding seat 482 sliding along the slide rail 481, a tensioning drive mechanism (not shown in the figure) that drives the sliding seat 482 to slide, and a transmission roller 483 mounted on the sliding seat 482. When the edge guard plate 9 passes around the transmission roller 483, the sliding seat 482 moves up and down as driven by the tensioning drive mechanism, thereby achieving tension on the edge guard plate 9. Alternatively, the tensioning drive mechanism can be omitted, and gravity tensioning can be achieved through configuration, i.e., changing from active tensioning to passive tensioning. The tensioning drive mechanism can be an electric cylinder, a lead screw mechanism, etc.

[0044] The fixing mechanism 6 is a synchronous belt mechanism located on the side of the rectangular item on the frame 1. The synchronous belt mechanism is used to clamp the edge protector 9 to the side of the rectangular item. Of course, the fixing mechanism 6 can also be other methods, such as adhesive bonding, electrostatic adsorption, etc., with the purpose of temporarily keeping the edge protector 9 on the side of the rectangular item until it is wrapped in a ring.

[0045] A bending mechanism 7 for bending the edge guard plate 9 is provided on the frame 1 above and / or below the fixing mechanism 6. The bending mechanism 7 is a folding conveyor belt. The folding conveyor belt is a flat belt or a synchronous belt, which is a common structure in the art and is mainly used to compress flat sheet materials during the conveying process, thereby bending them. In this solution, the bending mechanism 7 can be located below or above the fixing mechanism 6, and the bending mechanism 7 can also be lifted and lowered by the lifting mechanism 8.

[0046] The working principle of this utility model is as follows:

[0047] A rectangular item is input by the material conveying mechanism 2, unwound by the unwinding roller 41, guided by the guide roller 42, tensioned by the active tensioning mechanism, and then enters the clamping conveying mechanism 43, and then enters the cutting mechanism 45 through the guiding mechanism. The edge guard plate 9 located above the cutting mechanism 45 is adsorbed by the input fixing plate 44, and then cut by the cooperation of the female blade 453 and the female blade 451. The cut edge guard plate 9 is pushed out to one of the adsorption mechanisms by the input plate cylinder 46. This adsorption mechanism adsorbs the edge guard plate 9, and the input fixing plate 44 releases the edge guard plate 9, realizing the transfer. Then, the rotary conveying mechanism 51 drives the edge guard plate 9 on the adsorption mechanism to the side of the rectangular item. Because the edge guard plate 9 has a certain width, when the edge guard plate 9 is attached to one side of the rectangular item, it can move along the side of the rectangular item until the fixing mechanism 6 cooperates with the rectangular item to clamp the edge guard plate 9, and then the adsorption mechanism releases the adsorption, realizing the release of the edge guard plate 9. Then, the bending mechanism 7 is used to bend the upper and lower ends of the edge protector 9, so that the part exceeding the rectangular item fits against the upper and lower sides of the rectangular item. Finally, it enters the ring-shaped binding mechanism 3 to bind the rectangular item, so that the edge protector 9 is located within the binding line, thereby protecting the edges and corners of the rectangular item.

[0048] When a lifting mechanism 8 is provided, the height of the bending mechanism 7 can be controlled.

[0049] In this solution, all cylinders can be replaced with hydraulic cylinders, electric actuators, or other mechanisms capable of linear reciprocating motion. The conveyor belts mentioned above can be synchronous conveyor belts or other conveying mechanisms that can achieve the functions of this solution.
