Description

Device for material handling and packaging Technical Field

[0001] The present invention belongs to the technical field of material handling and packaging, and in particular relates to a device for material handling and packaging. Background Art

[0002] A packaging machine is a type of machine that packages products. For example, soybeans, corn, wheat, and fertilizers produced on large farms all need to be packaged and sold after harvesting.

[0003] A packaging machine is a mechanical device used to package various items. Its purpose is to protect goods and prevent them from being damaged by friction, deformation, decay, abrasion, moisture, and other factors. In modern society, packaging machines play a very important role in the packaging industry and are indispensable equipment in all walks of life.

[0004] The working principle of a packaging machine is generally to complete the entire packaging process through a machine system consisting of a conveying device, a filling device, a sealing device, and a cutting device. The necessity of a packaging machine lies in improving packaging efficiency while also ensuring product quality and safety.

[0005] Chinese patent application number CN201621106217.1 discloses a packaging machine system, which relates to the field of packaging machine technology and aims to solve the problem in existing packaging machine systems that the manual operation of packing multiple products into transport boxes is time-consuming, labor-intensive, and has high labor costs. The packaging machine system described in this patent includes: a driving device arranged next to the work platform between the thermoforming machine and the baling machine; a sensing device arranged on the conveyor belt between the thermoforming machine and the baling machine, the sensing device being used to determine the specific position of the products packaged by the thermoforming machine on the conveyor belt; a conveying device connected to the driving device, the conveying device being used to load the products packaged by the thermoforming machine into the transport box in the baling machine; and a control device electrically connected to the sensing device and the driving device, the control device being used to receive control signals sent by the sensing device and control the driving device to drive the conveying device to complete the packaging operation. This patent is mainly used in assembly lines for product packaging operations.

[0006] When packaging materials during transportation, the packaging bags and materials move together. The diameter of the bag opening is prone to become larger or tilted during transportation. Since some materials are fluid, unsealed packaging bags are prone to leak on the conveyor belt, which affects the material transportation and packaging process and even causes machine failure and safety hazards. At the same time, packaging machines are assembly line cycle operations, and higher requirements are placed on the quality of some connecting parts. It is necessary to ensure the service life of the equipment to reduce production costs.

[0007] Therefore, it is necessary to invent a device for material handling and packaging to solve the above problems.

[0018] The technical effects and advantages of the present invention are as follows:

[0019] 1. The present invention facilitates defining the top side edges of the packaging bag through the spiral effect of the two nuts and the screw on both sides, and the clamping rollers approach each other in the process of moving downward on the inner side of the inclined groove by utilizing the convex rod, and the two clamping rollers gradually approach the packaging bag during the downward movement. At this time, the two clamping rollers facilitate the preliminary clamping of the bag opening of the packaging bag, thereby reducing the bag opening diameter of the packaging bag; the convex rod drives the top end of the movable plate to move downward, and the two movable plates cause the inner ends of the two bottom plates to gradually rotate downward during the rotation process, and the bottom end of the packaging bag gradually moves downward with the rotation of the bottom plate. At this time, the spiral effect of the nut and the screw pulls the top side edges of the packaging bag, which can further reduce the top bag opening diameter of the packaging bag and prevent the bag opening of the packaging bag from shifting or the bag opening diameter from becoming larger during the movement.

[0020] 2. The present invention places the half ring on the top of the first slide rail, and the bottom surfaces of the rollers at both ends of the half ring first contact the top surface of the first slide rail. At this time, the weight of the rolling structure and the packaging structure is applied to the two half rings, and the weight applied to the half ring directly acts on the first slide rail through the rollers. The reaction force of the first slide rail on the rollers causes the rollers to drive the center rod to move up on the surface of the vertical rod. During the upward movement, the center rod squeezes the spring on the surface of the vertical rod. The elastic force of the spring can prevent the inner bottom surface of the half ring from directly contacting the top surface of the first slide rail, and the half ring uses the rollers to roll on the surface of the first slide rail, which can avoid sliding friction damage between the half ring and the first slide rail, and can improve the service life of the entire rolling structure.

[0021] 3. In the present invention, when the convex rod moves downward on the inner side of the inclined groove through the clamping roller, the convex rod drives the gear to move downward synchronously. Since the teeth of the gear and the bevel rack are engaged, the gear rotates during the downward movement, and the gear drives the clamping roller to rotate synchronously using the convex rod. The two clamping rollers rotate toward each other on both sides of the packaging bag, that is, the clamping roller on the left rotates counterclockwise, and the clamping roller on the right rotates clockwise. The two clamping rollers rotating in opposite directions will not push outward the top two sides of the packaging bag during the rotation process. At this time, the two clamping rollers can facilitate the gradual reduction of the opening diameter of the packaging bag during the process of approaching, so that the two clamping rollers approaching each other can stably clamp the top opening of the packaging bag, and the top opening of the packaging bag is always facing upward during the contact between the two clamping rollers rotating in opposite directions and the packaging bag.

[0022] 4. The present invention uses the design of the slide bar to enable the device to load materials and transport packaging bags more smoothly without causing leakage of the packaging bags, thereby continuously packaging the materials in a cycle, greatly saving packaging efficiency while ensuring packaging safety.

[0023] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] The present invention provides a device for material handling and packaging, as shown in FIG1 , comprising two first slide rails 1 and two second slide rails 2, wherein the first slide rail 1 is vertically positioned on top of the second slide rail 2, the first slide rail 1 and the second slide rail 2 being fixedly connected by a plurality of support rods 3, the first slide rail 1 and the second slide rail 2 being arranged parallel to each other, and the center lines of the first slide rail 1 and the second slide rail 2 being in the same vertical plane, a semi-ring 4 being slidingly provided on the top of the first slide rail 1, a limiting frame 5 being fixedly connected to the bottom inner side of the semi-ring 4, the two ends of the semi-ring 4 being slidably engaged with the first slide rail 1 by a rolling structure, a packaging structure for material handling and packaging is provided between the two limiting frames 5, and a packaging bag 6 is provided inside the packaging structure, the top side edges of the packaging bag 6 being correspondingly limited to the inner top of the packaging structure. The first slide rail 1 and the second slide rail 2 are installed according to the distance of material handling, thereby forming a circular assembly line for handling and packaging, and a plurality of packaging structures are installed on the circular assembly line. When the material needs to be transported and packaged, the packaging bag 6 is placed on the packaging structure accordingly, and after the top side of the packaging bag 6 is clamped with the top inner side of the packaging structure, the material is poured into the packaging bag 6 through the opening of the packaging bag 6. The packaging structure drives the packaging bag 6 to slide on the first slide rail 1 and the second slide rail 2 respectively using the rolling structure and the packaging structure. The first slide rail 1 and the second slide rail 2 are used to facilitate the transportation of the packaging structure. During the transportation process, the packaging structure is used to seal the top opening of the packaging bag 6. After transporting to the target location, the bottom of the packaging structure is opened, and the packaging bag 6 carrying the material can leak out from the bottom of the packaging structure, continuing to push the entire packaging structure to move, so that the new packaging bag 6 can be conveniently installed on the packaging structure. Using multiple packaging structures and a circulating assembly line, the materials can be continuously transported and packaged.

[0031] In Figures 2 and 3, the rolling structure includes rollers 7. Support plates 8 are fixedly connected to the tops of both ends of the semi-ring 4. The rollers 7 are located between the two opposing support plates 8. The semi-ring 4 utilizes the rollers 7 to flexibly engage with the top surface of the first slide rail 1. A vertical slot 9 is provided at the center of the support plate 8. A vertical rod 10 is vertically provided at the center of the vertical slot 9. The two vertical rods 10 are sleeved on the ends of a center rod 11, and the rollers 7 are rotatably sleeved on the surface of the center rod 11. A spring 12 is provided on the surface of the vertical rod 10, and the spring 12 is located at the top end of the center rod 11. When the packaging structure moves on the circulating assembly line, the packaging structure utilizes the rolling structure at both ends of the semi-ring 4 to move on the first slide rail 1. When the half ring 4 is placed on the top of the first slide rail 1, the bottom surfaces of the rollers 7 at both ends of the half ring 4 first contact the top surface of the first slide rail 1. At this time, the weight of the rolling structure and the packaging structure is applied to the two half rings 4. The weight applied to the half ring 4 acts directly on the first slide rail 1 through the rollers 7. The reaction force of the first slide rail 1 on the rollers 7 causes the rollers 7 to drive the center rod 11 to move up on the surface of the vertical rod 10. During the upward movement, the center rod 11 squeezes the spring 12 on the surface of the vertical rod 10. The elastic force of the spring 12 can prevent the inner bottom surface of the half ring 4 from directly contacting the top surface of the first slide rail 1, and the half ring 4 uses the rollers 7 to roll on the surface of the first slide rail 1, which can avoid sliding friction damage between the half ring 4 and the first slide rail 1, and can improve the service life of the entire rolling structure.

[0032] In Figures 1 and 2, two inclined grooves 13 are symmetrically provided on both sides of the surface of the limiting frame 5, and the distance between the tops of the two inclined grooves 13 is greater than the distance between the bottoms of the two inclined grooves 13. The packaging structure includes two clamping rollers 14, and the two clamping rollers 14 are respectively arranged corresponding to the two inclined grooves 13. Both ends of the clamping rollers 14 are provided with protruding rods 15. The clamping rollers 14 use the protruding rods 15 at both ends to slide with the inclined grooves 13 on one side of the two limiting frames 5 respectively. An electric heating device is provided on the inside of the clamping roller 14, and the clamping roller 14 is externally connected to a battery. Among them, the packaging bag 6 is set as a plastic packaging bag. When the two clamping rollers 14 gradually move downward, the two clamping rollers 14 use the convex rods 15 to move downward on the inner side of the inclined groove 13, and the two clamping rollers 14 gradually approach each other during the downward movement until the two clamping rollers 14 can continue to clamp the top opening of the packaging bag 6. The battery energizes the powered heating device inside the clamping rollers 14. At this time, the powered heating device generates heat and uses the clamping rollers 14 to act on the top opening of the packaging bag 6. The contact position between the surface of the packaging bag 6 and the heating clamping rollers 14 is tightly adhered under the clamping of the two clamping rollers 14, and the two heating clamping rollers 14 are used to facilitate the sealing of the top of the packaging bag 6.

[0033] In Figures 1 and 2, two bevel racks 16 are symmetrically provided on both sides of the outer side surface of the limiting frame 5. The two bevel racks 16 correspond to the two bevel grooves 13 one by one, and the teeth of the bevel racks 16 are directed downward. A gear 17 is fixedly provided on the surface of the protruding rod 15. The clamping roller 14 utilizes the gears 17 on the surfaces of the two protruding rods 15 to slide with the bevel grooves 13 on one side of the two limiting frames 5, and the inner side of the gear 17 corresponds to the outer side of the limiting frame 5. The protruding rod 15 utilizes the gear 17 to mesh with the teeth of the bevel rack 16. When the clamping roller 14 moves down inside the inclined groove 13 by using the convex rod 15, the convex rod 15 drives the gear 17 to move down synchronously. Since the gear 17 is meshed with the teeth of the bevel rack 16, the gear 17 rotates during the downward movement, and the gear 17 drives the clamping roller 14 to rotate synchronously by using the convex rod 15. The two clamping rollers 14 rotate toward each other on both sides of the packaging bag 6, that is, the clamping roller 14 on the left rotates counterclockwise and the clamping roller 14 on the right rotates clockwise. The two clamping rollers 14 rotating in opposite directions will not push out the top two sides of the packaging bag 6 during the rotation process. At this time, the two clamping rollers 14 can facilitate the gradual reduction of the opening diameter of the packaging bag 6 during the approach process, so that the two clamping rollers 14 approaching each other can stably clamp the top opening of the packaging bag 6, and the top opening of the packaging bag 6 is always upward during the contact between the two clamping rollers 14 rotating in opposite directions and the packaging bag 6.

[0034] In Figures 1 and 2, the surface of the protruding rod 15 is rotatably sleeved on the bottom end of the rotating frame 18. The rotating frame 18 is located on the inner side of the limiting frame 5, and the bottom end of the rotating frame 18 is located between the clamping roller 14 and the limiting frame 5. The top ends of two adjacent rotating frames 18 are rotatably sleeved on the surface of the screw 19. The inner end of the screw 19 is spirally sleeved with a nut 20. The top side of the packaging bag 6 is located between the outer side of the nut 20 and the top end of the rotating frame 18. The spiral fit of the nut 20 and the screw 19 defines the top side of the packaging bag 6. Two fixing bars 29 are fixedly provided on the inner side of the limiting frame 5. The outer end of the screw 19 is located between the two fixing bars 29, and the two fixing bars 29 define the sliding direction of the screw 19. When it is necessary to fix the top side of the packaging bag 6, loosen the nut 20, place the top side of the packaging bag 6 between the nut 20 and the top of the rotating frame 18, tighten the nut 20, and the spiral effect of the two nuts 20 and the screw 19 on both sides can facilitate the top side of the packaging bag 6 to be limited, so as to facilitate the opening of the top of the packaging bag 6. When the clamping roller 14 moves downward inside the inclined groove 13 using the protruding rod 15, the two clamping rollers 14 gradually approach each other during the downward movement. As the two clamping rollers 14 approach each other, the clamping rollers 14 use the two protruding rods 15 at both ends to drive the bottom ends of the two rotating frames 18 to gradually approach each other during the downward movement. Due to the limitation of the inner end of the screw 19 by the two fixing bars 29, the top ends of the two rotating frames 18 rotate on the surface of the screw 19, thereby preventing the screw 19 from deflecting during the rotation of the rotating frame 18. Because the screw 19 and the nut 20 cooperate to clamp the top opening of the packaging bag 6, when the two rotating racks 18 move down and rotate, causing the screw 19 to move up between the two fixing bars 29, the nuts 20 and the screw 19 on both sides pull the two top side edges of the packaging bag 6, so that the bag opening of the packaging bag 6 gradually decreases during the pulling process, making it easier for the two clamping rollers 14 to seal the bag opening of the packaging bag 6.

[0035] In Figures 1 and 2, the packaging structure also includes two bottom plates 21, which are arranged parallel to each other, and the bottom ends of the packaging bags 6 are placed correspondingly on the top surfaces of the two bottom plates 21. The outer sides of both ends of the two bottom plates 21 are provided with convex plates, and a through groove 22 is provided at the center of the convex plates. The two clamping rollers 14 are respectively arranged corresponding to the two bottom plates 21, and the surface of the convex rod 15 at the end of the clamping roller 14 is rotatably sleeved with the top end of the movable plate 23. The center of the movable plate 23 passes through the through groove 22 on the surface of the convex plate, and the bottom end of the movable plate 23 is rotatably connected to a rotating wheel 24, and the bottom end of the movable plate 23 uses the rotating wheel 24 to roll with the top surface of the second slide rail 2, and a screw 25 is spirally penetrated at the center of the end face of the convex plate, and the inner end of the screw 25 is fastened to the outer side surface of the movable plate 23. Place the protruding rods 15 at the ends of the two clamping rollers 14 on the top of the inclined groove 13. At this time, it is necessary to ensure that the two bottom plates 21 are in a horizontal state. When placing the packaging bag 6, place the bottom of the packaging bag 6 on the top of the two bottom plates 21. Adjust the position of the bottom plate 21 on the surface of the movable plate 23 according to the height of the packaging bag 6. Loosen the screws 25 and push the bottom plate 21 to move. The bottom plate 21 uses the through grooves 22 on the surface of the end protruding plate to move on the surface of the movable plate 23 until the top side of the packaging bag 6 is restricted by the nut 20 and the screw 19. Then tighten the screws 25 to restrict the bottom plate 21 to the movable plate 23. After the position of the bottom plate 21 is fixed, the rotating wheel 24 at the bottom of the movable plate 23 is placed on the second slide rail 2. At this time, the packaging structure can roll on the top surface of the second slide rail 2 using the rotating wheel 24 at the bottom of the movable plate 23.

[0036] In Figures 1 and 2, a slide 26 is provided on the outside of the two limiting frames 5. The two ends of the slide 26 are movably connected to the surfaces of the two protruding rods 15, and a slide groove for sliding cooperation with the protruding rods 15 is provided on the inner side of the top of the slide 26. A slide rod 27 is provided between the first slide rail 1 and the second slide rail 2. The slide rod 27 is fixedly connected to multiple support rods 3. A placement rod 28 corresponding to the slide rod 27 is provided on the outer side of the slide 26. The slide 26 always slides in contact with the top surface of the slide rod 27 using the placement rod 28. When the packaging structure uses the roller 7 and the rotating wheel 24 to move on the first slide rail 1 and the second slide rail 2 respectively, the protruding rod 15 at the end of the clamping roller 14 drives the slide 26 to move synchronously, and the slide 26 slides on the top surface of the slide bar 27 using the placement rod 28. Since the weight of the material carried by the packaging bag 6 and the packaging structure is applied to the slide 26 through the protruding rod 15, the slide 26 uses the placement rod 28 to squeeze the slide bar 27. The weight of the material carried by the packaging bag 6 and the packaging structure can make the placement rod 28 always in contact with the slide bar 27.

[0037] The sliding rod 27 includes a horizontal portion, an arc portion, a descending portion and an ascending portion.

[0038] When the slide 26 slides on the horizontal part of the slide rod 27 using the placement rod 28, the entire packaging structure and the packaging bag 6 can move smoothly on the circulation line, and it is convenient to pour materials into the packaging bag 6 through the top opening of the packaging bag 6.

[0039] When the slide 26 slides on the arc-shaped portion of the slide rod 27 using the placement rod 28, the placement rod 28 of the slide 26 first descends on the arc-shaped portion and then moves up. When the slide 26 moves down, the slide 26 uses the convex rod 15 to drive the clamping roller 14 to move down inside the inclined groove 13. The two clamping rollers 14 gradually approach the packaging bag 6 during the downward movement. At this time, the two clamping rollers 14 are convenient for preliminary clamping of the bag opening of the packaging bag 6, which can reduce the bag opening diameter of the packaging bag 6 and prevent the material inside the packaging bag 6 from flowing out of the bag opening. When the protruding rod 15 moves downward, it drives the top of the movable plate 23 downward. At this time, the bottom of the movable plate 23 rolls on the second slide rail 2 using the rotating wheel 24, increasing the distance between the bottom ends of the two movable plates 23. The two movable plates 23 rotate during this process, causing the two bottom plates 21 to rotate. At this time, the inner ends of the two bottom plates 21 gradually rotate downward, and the bottom end of the packaging bag 6 gradually moves downward following the rotation of the bottom plates 21. At this time, the spiral effect of the nut 20 and the screw 19 pulls on the top side of the packaging bag 6, further reducing the diameter of the top bag opening of the packaging bag 6. When the slide 26 moves upward, the sliding rod 27 pushes the slide 26 upward via the placement rod 28, causing the inner ends of the movable plate 23 to gradually move upward. The rotation of the movable plate 23 causes the two bottom plates 21 to return to a horizontal state.

[0040] When the slide 26 slides on the descending part of the slide rod 27 using the placement rod 28, referring to the sliding process in the arc-shaped part, the convex rod 15 always moves downward on the inner side of the inclined groove 13, and the convex rod 15 drives the rotation of the bottom plate 21 using the movable plate 23 to move the packaging bag 6 downward, and the nut 20 and the screw 19 clamp the top of the packaging bag 6 to reduce the diameter of the packaging bag 6, which facilitates the two clamping rollers 14 to gradually seal the bag mouth of the packaging bag 6 during the rotation process until the two bottom plates 21 can no longer support the packaging bag 6. At this time, the weight of the material inside the packaging bag 6 is greater than the clamping of the nut 20 and the screw 19 on the top side of the packaging bag 6. At this time, the packaging bag 6 carrying the material falls from between the two bottom plates 21, achieving the effect of transporting and packaging the material.

[0041] When the slide 26 slides on the rising part of the slide bar 27 using the placement rod 28, referring to the sliding process in the arc-shaped part, the protruding rod 15 always moves up on the inner side of the inclined groove 13, and the protruding rod 15 drives the rotation of the bottom plate 21 using the movable plate 23. The bottom plate 21 gradually tends to be horizontal during the rotation process until the protruding rod 15 moves to the top of the inclined groove 13. At this time, the placement rod 28 of the slide 26 gradually moves to the horizontal part of the slide bar 27. Repeating the above process facilitates the use of packaging bags 6 to carry out cyclic and continuous packaging of materials.

[0042] Working principle of the present invention:

[0043] Referring to Figures 1-3 of the specification, the first and second slide rails 1 and 2 are installed according to the distance the materials are to be transported, thereby forming a circular assembly line for transporting and packaging. When materials need to be transported and packaged, the bottom of the packaging bag 6 is placed on top of the two bottom plates 21. The position of the bottom plates 21 on the surface of the movable plate 23 is adjusted according to the height of the packaging bag 6. The screws 25 are loosened to push the bottom plates 21 to move. The bottom plates 21 move on the surface of the movable plate 23 using the grooves 22 on the surface of the end protrusions until the top side of the packaging bag 6 is restrained by the nut 20 and screw 19. The screws 25 are then tightened to restrain the bottom plates 21 on the movable plate 23.

[0044] The packaging structure is pushed to move, and the packaging structure uses the roller 7 and the rotating wheel 24 to move on the first slide rail 1 and the second slide rail 2 respectively. When it is transported to the target position, the bottom of the packaging structure is opened, and the packaging bag 6 carrying the material can leak out from the bottom of the packaging structure, and the entire packaging structure is continued to be pushed to move, so that the new packaging bag 6 can be installed on the packaging structure accordingly. Using multiple packaging structures and a circulating assembly line, the materials can be continuously transported and packaged.
