Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, specifically relating to an automatic product feeding and packaging equipment. Background Technology

[0002] In existing technology, after the blanking parts are processed and inspected, qualified parts are output one by one via a conveyor belt. Packaging bags are typically placed at the end of the conveyor belt to collect the output parts. When the number of parts in a packaging bag reaches a certain limit, workers must remove the bag from the end of the conveyor belt and replace it with a new bag for subsequent parts output. Workers then transfer the bags containing the parts to a sealing machine for heat sealing, facilitating centralized storage and transportation of the parts.

[0003] During the heat-sealing process of packaging the aforementioned parts, the packaging bags are manually placed and removed. Over extended periods, worker efficiency gradually decreases, ultimately impacting the overall packaging efficiency. Simultaneously, the packaging bags containing the parts need to be transferred to a sealing machine for heat sealing. This process requires workers to handle the packaging bags, placing a significant workload on them over time. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an automatic product unloading and packaging equipment to solve the technical problems of low efficiency in manual bag changing during parts packaging and high workload in heat sealing of packaging bag openings.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] An automated product unloading and packaging device includes a box conveying assembly, a bag feeding assembly, a bag opening assembly, and a heat sealing assembly. The box conveying assembly is used to convey material boxes that carry output parts.

[0007] The bag supply assembly includes a bag storage rack, and a bag opening transplanting assembly and a packaging bag transfer assembly mounted on the bag storage rack. The bag opening transplanting assembly includes a transplanting cylinder and a transplanting suction cup. The transplanting suction cup is mounted on the drive end of the transplanting cylinder and can rise or fall under the drive of the transplanting cylinder to achieve adsorption and lifting of the bag opening edge of the packaging bag.

[0008] The packaging bag transfer assembly includes a support bracket, a flipping bracket, a flipping drive assembly, and a gripper cylinder. The support bracket is fixed to the bag storage rack. The flipping bracket is rotatably coupled to the support bracket and can rotate around a pivot under the drive of the flipping drive assembly. The gripper cylinder is used to clamp the opening of the packaging bag lifted by the transfer suction cup.

[0009] The bag opening assembly includes two bag opening units. The two bag opening units are symmetrically arranged on the box support, and can adhere to the side of the packaging bag and open the bag opening.

[0010] The heat-sealing assembly includes two symmetrically arranged heat-sealing units. Each heat-sealing unit includes a heat-sealing drive cylinder and a heat-sealing strip. The heat-sealing strip can move closer to the center or further away from the center under the action of the heat-sealing drive cylinder, thereby achieving heat sealing of the bag opening.

[0011] Furthermore, the box conveying assembly includes a box support, an empty box conveying assembly, a box transfer assembly, and a full box output assembly. The box support has two layers: an upper material feeding layer and a lower output layer. The empty box conveying assembly and the full box output assembly are respectively located in the material feeding layer and the output layer. The box transfer assembly is used to transfer the material boxes output from the empty box conveying assembly to the full box output assembly.

[0012] Furthermore, the box transfer assembly includes a lifting bracket and a transfer drive cylinder. The lifting bracket is slidably connected to the box support and can rise or fall under the drive of the transfer drive cylinder.

[0013] Furthermore, the empty box conveying assembly is equipped with a lifting assembly. The lifting assembly is located directly below the parts output port. The lifting assembly includes a lifting bracket and two sets of lifting drive assemblies. The two sets of lifting drive assemblies are symmetrically arranged on both sides of the box support, and are used to drive the lifting bracket to rise or fall.

[0014] Furthermore, both the lifting bracket and the lowering bracket include a central support section and mounting sections on both sides. The support section includes multiple support frames arranged at intervals in sequence. Each support frame is located within the interval area between two adjacent conveying rollers.

[0015] Furthermore, the tilting drive assembly includes a tilting drive cylinder, and a gear and a rack that mesh with each other. The gear is fixed to the rotating shaft of the tilting bracket. The rack is slidably connected to the support bracket and can slide under the drive of the tilting drive cylinder.

[0016] Furthermore, the bag-opening unit includes a bag-opening cylinder, a mounting bracket, and multiple bag-opening suction cups. The bag-opening cylinder is fixed to the box body bracket. Each bag-opening suction cup is fixed to the drive end of the bag-opening cylinder via the mounting bracket.

[0017] Furthermore, the bag opening assembly also includes two auxiliary units. The two auxiliary units are symmetrically arranged on the box support, and their arrangement direction is perpendicular to the arrangement direction of the two bag opening units, so as to cooperate with the bag opening units to form an adsorption and unfolding around the bag opening.

[0018] Furthermore, the auxiliary unit includes an auxiliary suction cup and an auxiliary drive cylinder. The auxiliary suction cup can move towards the center or retract outward under the action of the auxiliary drive cylinder.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention utilizes a box conveying assembly, a bag feeding assembly, a bag opening assembly, and a heat sealing assembly. The bag feeding assembly includes a bag storage rack, and on the rack, a bag opening transfer assembly and a bag transport assembly. The bag transport assembly transfers stacked bags one by one to the bag opening assembly, where the bag opening is opened, thus automating bag changing at the output of the die-cutting machine and ensuring efficient bag changing. Simultaneously, after a predetermined number of parts have been placed into the bag, the heat sealing assembly heat-seals the bag opening, reducing the workload for workers in subsequent bag transfers and heat sealing of the bags containing parts.

[0028] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1 and 2 As shown, an automatic product unloading and packaging device is installed directly below the part output port of a die-cutting processing equipment, used to automate the packaging and transfer of die-cut parts. The specific structure of the device includes a box conveying assembly 1, a bag feeding assembly 2, a bag opening assembly 3, and a heat sealing assembly 4. The box conveying assembly 1 is used to convey empty material boxes to directly below the part output port of the die-cutting processing equipment, and to transfer and output the material boxes when the packaging bags in the material boxes are full of parts.

[0031] The bag feeding assembly 2 is used to transfer stacked packaging bags to the opening position of an empty material box, and the bag opening assembly 3 opens the packaging bag. The heat sealing assembly is used to seal the packaging bag when it contains a sufficient number of parts.

[0032] like Figure 2As shown, the box conveying assembly 1 includes a box support 1-1, an empty box conveying assembly 1-2, a box transfer assembly 1-3, and a full box output assembly 1-4. The box support 1-1 has two layers: an upper material receiving layer and a lower output layer. The empty box conveying assembly 1-2 and the full box output assembly 1-4 are respectively located in the material receiving layer and the output layer. During processing, empty boxes are conveyed by the empty box conveying assembly 1-2 to a position directly below the part output port. When the packaging bag in the box is full of parts, it is lowered by the box transfer assembly 1-3 into the full box output assembly 1-4 for output.

[0033] Both the empty box conveying assembly 1-2 and the full box output assembly 1-4 include multiple conveying rollers. Each conveying roller has a built-in power roller drive. Each conveying roller can rotate under the drive of its respective power roller, thereby realizing the conveying of the material box.

[0034] The box transfer assembly 1-3 includes a lifting bracket and a transfer drive cylinder. The lifting bracket is slidably connected to the box support 1-1 and can rise or fall under the drive of the transfer drive cylinder, transferring the material boxes output from the empty box conveying assembly 1-2 to the full box output assembly 1-4.

[0035] Furthermore, the empty box conveying assembly 1-2 is equipped with a lifting assembly 1-5. The lifting assembly 1-5 is located directly below the parts output port and is used to lift the empty material box, preventing damage to the parts during the output process due to excessive falling height. Specifically, the lifting assembly 1-5 includes a lifting bracket 1-5-1 and two sets of lifting drive assemblies 1-5-2. The two sets of lifting drive assemblies 1-5-2 are symmetrically arranged on both sides of the box support 1-1, used to drive the lifting bracket 1-5-1 to lift or lower, thereby realizing the lifting of the material box when receiving parts and the lowering and outputting after receiving.

[0036] In this embodiment, the lifting drive assembly 1-5-2 includes a lifting cylinder and two guide rods. The two guide rods are spaced apart, and their tops both pass through the side edge of the lifting bracket 1-5-1. The telescopic end of the lifting cylinder is connected to the lifting bracket 1-5-1, enabling it to lift the lifting bracket 1-5-1 when extended and to lower the lifting bracket 1-5-1 when retracted.

[0037] Furthermore, such as Figure 3 As shown, both the lifting bracket 1-5-1 and the lifting bracket include a central support section and mounting sections on both sides. The support section comprises multiple support frames arranged at intervals. Each support frame is located within the interval area between two adjacent conveyor rollers, ensuring that in the initial state, the material box can smoothly enter the area of ​​the lifting bracket 1-5-1 or the lifting bracket under the conveying of the rollers, and rise or fall accordingly.

[0038] like Figure 4 As shown, the bag supply assembly 2 includes a bag storage rack 2-1, and a bag opening transfer assembly 2-2 and a packaging bag transfer assembly 2-3 disposed on the bag storage rack 2-1. Multiple packaging bags are stacked on the bag storage rack 2-1. The bag opening transfer assembly 2-2 is used to absorb and lift the edges near the bag opening. The packaging bag transfer assembly 2-3 is used to transfer the packaging bags lifted by the bag opening transfer assembly 2-2 into the bag opening assembly 3 for opening.

[0039] The bag-mouth transplanting assembly 2-2 includes a transplanting cylinder 2-2-1, a connecting bracket, and two transplanting suction cups 2-2-2. The transplanting cylinder 2-2-1 is fixed to the supporting bracket 2-3-1. The two transplanting suction cups 2-2-2 are symmetrically arranged on the drive end of the transplanting cylinder 2-2-1 via the connecting bracket, and can rise or fall under the drive of the transplanting cylinder 2-2-1. When the transplanting suction cup 2-2-2 descends to fit against the uppermost packaging bag, it is suctioned to the edge of the bag opening by an external air source. After suction is complete, the transplanting cylinder 2-2-1 drives it upward until it reaches the clamping area of ​​the packaging bag transfer assembly 2-3.

[0040] The packaging bag transfer assembly 2-3 includes a support bracket 2-3-1, a flipping bracket 2-3-2, a flipping drive assembly, and two gripper cylinders 2-3-3. The support bracket 2-3-1 is fixed to the bag storage rack 2-1. The middle part of the flipping bracket 2-3-2 is rotatably engaged with the top of the support bracket 2-3-1, allowing it to rotate around a pivot under the drive of the flipping drive assembly. The two gripper cylinders 2-3-3 are symmetrically arranged on both sides of the flipping bracket 2-3-2, clamping the packaging bag when its opening enters the gripping area of ​​the cylinders. After the gripping cylinders have finished clamping the bag opening, the flipping bracket 2-3-2 flips via the flipping drive assembly, moving the clamped packaging bag into the opening area of ​​the opening assembly 3.

[0041] In this embodiment, the flipping drive assembly includes a flipping drive cylinder 2-3-4, and a meshing gear 2-3-5 and a rack 2-3-6. The gear 2-3-5 is fixed to the rotating shaft of the flipping bracket 2-3-2. The rack 2-3-6 is slidably connected to the support bracket 2-3-1 and can slide under the drive of the flipping drive cylinder 2-3-4. The gear 2-3-5 rotates under the drive of the rack 2-3-6, thereby achieving the flipping of the flipping bracket 2-3-2.

[0042] like Figure 5 and 6As shown, the bag opening assembly 3 includes two bag opening units and two auxiliary units. The two bag opening units are symmetrically arranged on the box support 1-1, capable of adsorbing the sides of the packaging bag and opening the bag opening. The two auxiliary units are symmetrically arranged on the box support 1-1, with their arrangement direction perpendicular to the arrangement direction of the two bag opening units, enabling them to work in conjunction with the bag opening units to open the packaging bag around its opening.

[0043] The bag opening unit includes a bag opening cylinder 3-1, a mounting bracket, and multiple bag opening suction cups 3-2. The bag opening cylinder 3-1 is fixed to the box body bracket 1-1. Each bag opening suction cup 3-2 is fixed to the drive end of the bag opening cylinder 3-1 via the mounting bracket.

[0044] The auxiliary unit includes an auxiliary suction cup 3-3 and an auxiliary drive cylinder. The auxiliary suction cup 3-3 can move towards the center under the action of the auxiliary drive cylinder, thereby adsorbing and extending the corresponding side edge of the packaging bag opening.

[0045] Initially, the suction cups 3-2 in the two opening units are spaced apart, forming an opening area. When the packaging bag enters the opening area driven by the packaging bag transfer assembly 2-3, the opening cylinders 3-1 in the two opening units drive the suction cups 3-2 to move towards the center until they are in contact with the packaging bag in the opening area. The contacted suction cups 3-2 use an external air source to adhere to both sides of the packaging bag. Simultaneously, the gripper cylinders 2-3-3 in the packaging bag transfer assembly 2-3 release their grip on the packaging bag. After adsorption of the packaging bag is completed, the driving ends of the opening cylinders 3-1 in the two opening units retract in the opposite direction, thus opening the packaging bag. Subsequently, the auxiliary suction cups 3-3 in the two auxiliary units move towards the center under the drive of the auxiliary drive cylinders, adsorbing and extending the corresponding side edges of the packaging bag opening, thus expanding the packaging bag opening around its perimeter. Parts output from the parts output port can then fall smoothly into the packaging bag.

[0046] The heat-sealing assembly includes two symmetrically arranged heat-sealing units. Each heat-sealing unit includes a heat-sealing drive cylinder and a heat-sealing strip. The heat-sealing strip moves towards the opening of the packaging bag under the action of the heat-sealing drive cylinder. The cooperation of the heat-sealing strips in the two heat-sealing units achieves clamping and heat sealing of the packaging bag opening. During processing, when the number of parts in the packaging bag reaches a specified target, the suction cups 3-2 in each opening unit and the auxiliary suction cups 3-3 in each auxiliary unit release their suction force, allowing the two sealing strips to smoothly complete the heat sealing of the packaging bag opening.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
