Description

Technical Field

[0001] This application relates to the technical field of logistics equipment, and particularly relates to a bubble film packaging device for express parcels. Background Art

[0002] With the improvement of people's living standards, there are more and more various products. In recent years, the logistics and transportation industry has developed rapidly. Especially the drive of e-commerce for the logistics industry has made modern logistics widely appear in life and work. Logistics transportation is inseparable from the packaging and protection of products. At present, most of the packaging is completed manually or by semi-automatic equipment, with low packaging efficiency; Bubble film is a commonly used packaging material. Since bubble film is a multi-layer composite film with small bubbles of a certain density filled between adjacent layers, it can better wrap and protect products. At the same time, precisely because there are small bubbles of a certain density filled between adjacent layers of the multi-layer composite film of bubble film, its thickness can reach 5MM - 10MM, which is relatively thick; and due to the existence of bubbles, it is soft, and it is not easy to cut two layers of bubble film with a general cutter, and it is not easy to heat-seal two layers of bubble film with a general heat-sealing structure. Therefore, it is not easy to cut and heat-seal when using bubble film for packaging with a general device. Summary of the Invention

[0003] The technical problem solved by this application is to provide a solution for the deficiencies in the background art.

The hopper is arranged on one side of the bracket away from the transverse sealing and cutting device or the longitudinal sealing and cutting device, and the transfer mechanism can move the waste generated by the transverse sealing and cutting device or the longitudinal sealing and cutting device into the hopper.

[0009] Further, the hopper includes a bottom plate, side plates, and a first swing driving member. The bottom plate is hinged to the bracket, and the first swing driving member drives the bottom plate to swing on the bracket to adjust the inclination of the bottom plate. The side plates are arranged on the outer sides of the bottom plate.

[0010] Further, the transfer mechanism includes a second swing arm, a shaft rod, a second swing driving member, and a clamp.

The conveying device and the bubble film feeding device can complete the wrapping of the bubble film on the upper and lower sides of the express parcel to be packaged. Through the transverse sealing and cutting device and the longitudinal sealing and cutting device, the bubble film at the ends and the front and rear sides can be cut off and heat-sealed, so as to continuously complete the wrapping, cutting, and sealing of the bubble film, with convenient packaging and high packaging efficiency. Both the upper cutting knife and the upper heat-sealing plate are connected to the upper cutting knife seat through elastic members, and the lower heat-sealing plate is connected to the lower cutting knife seat through an elastic member. Thus, when the upper cutting knife, the upper heat-sealing plate, and the lower heat-sealing plate perform relative actions for cutting and hot pressing, there is a buffering effect, which can slow down the speed of cutting and heat sealing, increase the force of cutting and heat sealing, make the cutting more thorough, completely cut the bubble film, and also make the hot pressing time longer and the force greater, and the hot pressing between the two layers of bubble film is more firm. A U-shaped groove is provided on the lower heat-sealing plate. When the upper cutting knife cuts the bubble film, it can be inserted into the U-shaped groove with a deeper depth to completely cut the bubble film with a thicker thickness and softer texture, ensuring that the bubble film is completely cut off.

Detailed implementation manners

[0027] For the convenience of those skilled in the art to understand, the present application will be further described in detail below in conjunction with the drawings and embodiments.

[0028] Embodiment 1

[0029] Refer to Figures 1 to 11 , an express parcel bubble wrap packing equipment for packing express parcels. The packing uses bubble wrap to cover, and can cut and heat-seal the bubble wrap with a relatively thick thickness and air bubbles in the interlayer. The packing is convenient and fast. The express parcel bubble wrap packing equipment includes a conveying device 1, a bubble wrap feeding device 2, a transverse sealing and cutting device 3, and a longitudinal sealing and cutting device 4. The bubble wrap feeding device 2, the transverse sealing and cutting device 3, and the longitudinal sealing and cutting device 4 are sequentially arranged in the conveying direction of the conveying device 1; the conveying device 1 conveys the express parcels to be packed, and the bubble wrap feeding device 2 sends the bubble wrap to the upper and lower sides of the express parcels to be packed on the conveying device 1. During the conveying of the express parcels to be packed, the bubble wrap conveyed by the bubble wrap feeding device 2 covers the upper and lower sides. Then, the express parcels covered with bubble wrap are conveyed by the conveying device 1 to the transverse sealing and cutting device 3 for cutting and heat-sealing the bubble wrap at the front end in the conveying direction, and are conveyed to the longitudinal sealing and cutting device 4 for cutting and heat-sealing the bubble wrap on the front and rear sides in the conveying direction.

[0030] Refer to Figures 4 to 7, the horizontal sealing and cutting device 3 and the vertical sealing and cutting device 4 have the same structure. Both can perform heat sealing while cutting the bubble film. The horizontal sealing and cutting device 3 and the vertical sealing and cutting device 4 both include a carriage, an upper cutter seat, an upper cutter, an upper heat sealing plate, a lower cutter seat, a lower heat sealing plate, a driving mechanism, and an elastic member. In this embodiment, the vertical sealing and cutting device 4 is taken as an example for illustration, and the horizontal sealing and cutting device 3 can be set with reference to the vertical sealing and cutting device 4. The vertical sealing and cutting device 4 includes a carriage 41, an upper cutter seat 42, an upper cutter 43, an upper heat sealing plate 44, a lower cutter seat 45, a lower heat sealing plate 46, a driving mechanism 47, and an elastic member 48. The upper cutter seat 42 and the lower cutter seat 45 are both slidably arranged on the slide rod of the carriage 41 through linear bearings. The driving mechanism 47 drives the upper cutter seat 42 and the lower cutter seat 45 to slide relative to or away from each other on the carriage 41, so that the upper cutter 43, the upper heat sealing plate 44, and the lower heat sealing plate 46 connected to the upper cutter seat 42 and the lower cutter seat 45 can move relative to or away from each other. The relative movement of the upper cutter 43 and the lower heat sealing plate 46 realizes the function of cutting the bubble film, and the relative movement of the upper heat sealing plate 44 and the lower heat sealing plate 46 realizes the heat sealing function. The upper cutter 43 and the upper heat sealing plate 44 are both connected to the upper cutter seat 42 through the elastic member 48, and the lower heat sealing plate 46 is connected to the lower cutter seat 45 through the elastic member 48. Thus, when the upper cutter 43, the upper heat sealing plate 44, and the lower heat sealing plate 46 move relative to each other for cutting and hot pressing, it has a buffering effect, which can slow down the cutting and heat sealing speed, increase the cutting and heat sealing force, make the cutting more thorough, completely cut the bubble film, and also make the hot pressing time longer and the force greater, and the two layers of bubble film are hot pressed more firmly. The above elastic member 48 can adopt a telescopic spring.

[0031] Refer to Figures 4 to 7 , a U-shaped groove 461 is provided on the lower heat sealing plate 46, and the upper cutter 43 can be inserted into the U-shaped groove 461. Thus, when the upper cutter 43 cuts the bubble film, it can be inserted into the deeper U-shaped groove 461 to completely cut the relatively thick and soft-textured bubble film, ensuring that the bubble film is completely cut. When the upper heat sealing plate 44 and the lower heat sealing plate 46 move towards each other, they can be abutted together, thereby hot pressing the two layers of bubble film located between the upper heat sealing plate 44 and the lower heat sealing plate 46 together. Both the upper heat sealing plate 44 and the lower heat sealing plate 46 are connected with heating wires or other heating elements to heat the upper heat sealing plate 44 and the lower heat sealing plate 46. A thermocouple can also be provided on the upper heat sealing plate 44 and the lower heat sealing plate 46 to control the temperature of the upper heat sealing plate 44 and the lower heat sealing plate 46. The cutting edge of the upper cutter 43 is preferably in a serrated structure, so as to better cut the relatively thick and soft-textured bubble film.

[0032] Refer to Figures 4 to 7, the driving mechanism 47 can adopt the following structure: it includes a first swing arm 471, an upper connecting rod 472, a lower connecting rod 473 and a telescopic driving member 474. The first swing arm 471 is swingably arranged on the carriage 41 through a rotating shaft, and the telescopic driving member 474 drives the first swing arm 471 to swing; the telescopic driving member 474 can adopt a telescopic cylinder, so as to drive the first swing arm 471 to swing back and forth through the telescopic movement of the telescopic cylinder. One end of the upper connecting rod 472 is rotatably connected to one end of the first swing arm 471, and the other end of the upper connecting rod 472 is rotatably connected to the upper cutter seat 42; one end of the lower connecting rod 473 is rotatably connected to the other end of the first swing arm 471, and the other end of the lower connecting rod 473 is rotatably connected to the lower cutter seat 45. Therefore, when the telescopic cylinder drives the first swing arm 471 to swing back and forth, it can drive the upper cutter seat 42 and the lower cutter seat 45 to move towards or away from each other, and the upper cutter 43 and the upper heat-sealing plate 44 connected to the upper cutter seat 42 and the lower heat-sealing plate 46 connected to the lower cutter seat 45 can perform relative movements to complete cutting and hot pressing. The above structure can realize the actions of the two mechanisms of the upper cutter seat 42 and the lower cutter seat 45 with only one telescopic driving member 474, simplifies the structure of the equipment, enhances the stability of the equipment, and reduces the cost of the equipment at the same time.

[0033] Refer to Figures 4 to 7 , as a further preferred solution, the upper cutter 43 is preferably clamped in the middle of the upper heat-sealing plate 44. The upper heat-sealing plate 44 can be set into two pieces, and the upper cutter 43 is clamped between the two heat-sealing plates; or a U-shaped groove can be provided on the upper heat-sealing plate 44, and the upper cutter 43 is clamped in the U-shaped groove. Clamping the upper cutter 43 in the middle of the upper heat-sealing plate 44 can better heat the upper cutter 43 through the upper heat-sealing plate, so that it is easier for the upper cutter 43 to cut the plastic bubble film. Heat insulation plates 49 are provided on both sides of the upper heat-sealing plate 44 to prevent the high-temperature upper heat-sealing plate 44 from scalding the operators; the heat insulation plates 49 are preferably set to be longer. When the upper heat-sealing plate 44 and the lower heat-sealing plate 46 are abutted together, the heat insulation plates 49 can block on both sides of the lower heat-sealing plate 46 to prevent the high temperature of the lower heat-sealing plate 46 from scalding the operators. The heat insulation plates 49 can adopt a plate structure with better heat insulation performance in the prior art.

[0034] Refer to Figures 1 to 3The bubble film feeding device 2 includes an upper feed roller 21, an upper guide roller 22, a lower feed roller 23 and a lower guide roller 24. The upper feed roller 21 and the upper guide roller 22 are used to convey the upper layer of bubble film, and the upper feed roller 21 and the upper guide roller 22 are connected together through the bubble film. The lower feed roller 23 and the lower guide roller 24 are used to convey the bubble film wrapped in the lower layer, and are also connected through the bubble film. Multiple upper guide rollers 22 and lower guide rollers 24 can be set on the conveying path of the bubble film to better guide the bubble film; the upper feed roller 21 and the lower feed roller 23 can adopt structures such as an inflatable shaft, and a motor can also be set to drive the upper feed roller 21 and the lower feed roller 23 to rotate and feed. A film pulling mechanism may be provided at the position where the bubble film is coated on the conveying device 1 to pull the film forward; or the film pulling mechanism may not be provided, and the bubble film may be pulled forward by the action of the conveying device 1 (the package is placed on the conveying device 1 and moves with it, and the rear ends of the upper and lower layers of bubble film have been heat-sealed and fixed together. When the package moves with the conveying device 1, it can support the upper and lower bubble films and push them backward, thereby eliminating the need for a separate film pulling mechanism).

[0035] See also Figure 8 and Figure 9 In order to better collect and process the waste scraps generated when the bubble film is sealed and cut, a waste processing device 5 is provided on the outside of the transverse sealing and cutting device 3 and the longitudinal sealing and cutting device 4. The waste processing device 5 includes a bracket 51, a transfer mechanism 52 and a hopper 53. The hopper 53 is arranged on the side of the bracket 51 away from the transverse sealing and cutting device 3 or the longitudinal sealing and cutting device 4. The transfer mechanism 52 can move the waste generated by the transverse sealing and cutting device 3 or the longitudinal sealing and cutting device 4 into the hopper 53, and then further transfer and process it through the hopper 53. The hopper 53 is arranged on the side away from the transverse sealing and cutting device 3 or the longitudinal sealing and cutting device 4, and the sealed and cut waste is transferred from the transverse sealing and cutting device 3 or the longitudinal sealing and cutting device 4 by the transfer mechanism 52, so that there is more space on the side away from the transverse sealing and cutting device 3 or the longitudinal sealing and cutting device 4 to set a larger hopper 53, temporarily store more waste, reduce the frequency of waste processing in the hopper 53, and improve production efficiency.

[0036] See also Figure 8 and Figure 9, the hopper 53 preferably adopts the following structure: including a bottom plate 531, side plates 532 and a first swing driving member 533. The bottom plate 531 is hinged to the bracket 51 through a hinge. The first swing driving member 533 drives the bottom plate 531 to swing on the bracket 51, so as to adjust the inclination of the bottom plate 531, making it easier for the waste on the bottom plate 531 to slide off the bottom plate 531, thus facilitating the further transfer and treatment of the waste. The first swing driving member 533 can adopt a telescopic cylinder, and drives the bottom plate 531 to swing by telescoping. The side plates 532 are arranged outside the bottom plate 531 to prevent the waste from flowing out of the outside of the bottom plate 531. A waste collection groove can be further arranged below the bottom plate 531 to collect the waste sliding down from the bottom plate 531. When treating the waste, the waste can be removed through the waste collection groove for treatment.

[0037] Refer to Figure 8 and Figure 9 , the transfer mechanism 52 preferably adopts the following structure: including a second swing arm 521, a shaft rod 522, a second swing driving member 523 and a clamping jaw 524. The shaft rod 522 is rotatably arranged on the bracket 51 through a bearing. The clamping jaw 524 is arranged on the shaft rod 522. The second swing arm 521 is fixed at one end of the shaft rod 522. The second swing driving member 523 is installed on the bracket 51 and drives the second swing arm 521 to swing. Thus, the clamping jaw 524 on the shaft rod 522 can be driven by the second swing driving member 523 to swing back and forth on both sides of the bracket 51, and the bubble film waste generated by the transverse sealing and cutting device 3 or the longitudinal sealing and cutting device 4 is transferred to the side where the hopper 53 is located. The second swing driving member 523 can adopt a telescopic cylinder, and the clamping jaw 524 can adopt a pneumatic finger and a material clamp, and the material clamp is driven by the pneumatic finger to clamp the bubble film waste.

[0038] Refer to Figures 1 to 3 , as a further preferred solution, it is preferably to set a sorting device 6 and an identification device 7. The sorting device 6 is connected to the conveying device 1 and is arranged at the front end of the transverse sealing and cutting device 3, so as to identify and sort the express packages conveyed by the conveying device 1, remove the express packages with incorrect models, and wrap the express packages with qualified models with bubble film. The identification device 7 is arranged above the sorting device 6 to identify the express packages below; the identification device 7 can adopt a scanning gun to scan the barcode information on the express package to identify the express package.

[0039] Refer to Figure 10 and 11, the sorting device 6 can adopt the following structure: it includes a horizontal conveying mechanism 61 and a vertical conveying mechanism 62. Both the horizontal conveying mechanism 61 and the vertical conveying mechanism 62 are arranged on the frame 63. The horizontal conveying mechanism 61 and the vertical conveying mechanism 62 are two independently operating conveying mechanisms. The horizontal conveying mechanism 61 can move horizontally to convey the compliant packages to the rear section for bubble film wrapping; the vertical conveying mechanism 62 can move longitudinally to longitudinally send out the express packages with incorrect models from the sorting device 6 for rejection, and they will not flow to the rear section for bubble film wrapping.

[0040] Refer to Figure 10 and 11 , the horizontal conveying mechanism 61 includes a plurality of belts 611 arranged in parallel, belt pulley shafts 612, a synchronous belt 613, and a motor 614. The synchronous belt 613 is drivingly connected between the motor 614 and the belt pulley shafts 612. Each belt 611 is wound around the two belt pulley shafts 612 in parallel. Thus, the motor 614 can drive each belt 611 to rotate synchronously to convey the express packages for bubble film wrapping to the rear section conveyor belt.

[0041] Refer to Figure 10 and 11 , the vertical conveying mechanism 62 includes a lifting frame 621, a lifting drive assembly 622, a plurality of rollers 623, a motor 625, and a synchronous belt 624. Each of the rollers 623 is arranged in parallel on the lifting frame 621. The synchronous belt 624 is drivingly connected between the motor 625 and each of the rollers 623 and can drive each of the rollers 623 to rotate synchronously, thereby driving the express packages on the rollers to move for rejection. Each of the rollers 623 is parallel and adjacent to the belt 611. The lifting drive assembly 622 drives the lifting frame 621 to lift and lower. The rollers 623 can rise above each belt 611 or drop below the belt 611. For the express packages that need to be continuously conveyed to the rear section for bubble film wrapping, the lifting drive assembly 622 drives the lifting frame 621 to lower, so that the rollers 623 drop below the belt 611, and thus the packages are supported on the belt 611 and conveyed to the rear section for bubble film wrapping through the belt 611; for the express packages with incorrect models that need to be rejected, the lifting drive assembly 622 drives the lifting frame 621 to lift, and the rollers 623 rise above each belt 611. The packages are supported by the rollers 623, and when the rollers 623 rotate, the packages can be rejected out of the sorting device 6 and cannot reach the rear section for bubble film wrapping.

[0042] Refer to Figure 10 and 11, the lifting drive assembly 622 can adopt the following structure: including a rocker 6222, a connecting member 6223 and a telescopic cylinder 6221. The rocker 6222 is rotatably arranged on a lower fulcrum through a rotating shaft. The lower end of the connecting member 6223 is rotatably connected to the upper end of the rocker 6222 through a rotating shaft. The upper end of the connecting member 6223 is connected to the lifting frame 621 through a rotating shaft. The telescopic cylinder 6221 drives the rocker 6222 to swing around the lower fulcrum. The lifting frame 621 is slidably arranged on the machine frame 63 through a slide rail mechanism. Therefore, when the telescopic cylinder 6221 drives the rocker 6222 to swing, the vertical lengths of the rocker 6222 and the connecting member 6223 will change, so as to drive the lifting frame 621 to lift and lower, and the roller 623 on the lifting frame 621 will also lift and lower accordingly.

[0043] Refer to Figures 1 to 3 , as a further preferred solution, a labeling device 8 is also provided. The labeling device 8 is arranged above the conveying device 1 and is located between the transverse sealing and cutting device 3 and the longitudinal sealing and cutting device 4 or at the rear end of the longitudinal sealing and cutting device 4. After the bubble film is wrapped, the logistics information of the express package is pasted outside the bubble film to facilitate transportation according to the material information. The labeling device 8 includes a manipulator and a labeling machine. The logistics information label is printed by the labeling machine, and the logistics information label is pasted outside the package by the manipulator.

[0044] Refer to Figures 1 to 11 , when the express package bubble film packing equipment of this embodiment works, the package is placed at the front end of the conveying device 1 manually or by a manipulator. The conveying device 1 conveys the package to the sorting device 6 for sorting. The qualified packages are further conveyed to the transverse sealing and cutting device 3 through the conveying device 1, and the unqualified ones are removed; while the conveying device 1 is conveying, the upper and lower sides of the package are covered with bubble film, and the two layers of bubble film at the rear end of the conveying direction are heat-sealed together by an upper sealing and cutting action (when cutting, it is cut from the middle of the heat-sealing mouth, and the two layers of bubble film on one side of the package and one side of the bubble film feeding device 2 are heat-sealed together); after the upper and lower sides of the package are covered with bubble film, the conveying device 1 conveys the package to the transverse sealing and cutting device 3 for sealing and cutting the front-end bubble film, and then conveys the package to the longitudinal sealing and cutting device 4 for sealing and cutting the bubble film on the front and rear sides of the package; the waste generated by the sealing and cutting is processed by the waste treatment device 5.

[0045] Obviously, the above embodiments of the present application are only examples clearly described for the present application, and are not limitations on the implementation manners of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
