Description

Technical Field

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

[0002] Currently, the packaging design for 3-inch car models typically involves placing the model inside a transparent blister pack (pre-formed during the blister forming process), covering it with a special card, and then heat-sealing it to firmly seal the blister pack and card. This allows for a direct presentation of the product to customers. However, due to the large production volume of 3-inch car models, the existing packaging process faces capacity bottlenecks. Firstly, the blister forming and heat-sealing processes are independent, resulting in low overall packaging efficiency and requiring separate storage of the blister packs, increasing warehousing costs. Secondly, during production, workers can only heat-blow each model individually, leading to long production times, low productivity, and high labor costs. Furthermore, the high intensity and prolonged labor can cause operator fatigue, affecting packaging quality. Utility Model Content

[0003] Based on this, in order to improve the production capacity of the thermoforming process in the packaging process, the purpose of this utility model is to provide a packaging equipment for models, which can realize standardized, precise and efficient mechanized packaging of three-inch series car model products.

[0004] A packaging device for models, comprising: The rubber cover forming and feeding mechanism uses vacuum negative pressure to adsorb the preheated and softened rubber sheet onto the mold surface to shape it into a rubber cover. The model feeding mechanism places the model into the plastic cover; The card feeding mechanism covers the upper surface of the adhesive cover with card paper; The packaging mechanism heat-presses and bonds the card and the adhesive cover to obtain the finished package.

[0005] Compared with existing technologies, this utility model provides a model packaging equipment that combines the glue cover preparation process and the hot pressing bonding process, and uses machinery to replace manual labor to realize continuous and mechanized model packaging, which greatly improves model packaging efficiency, reduces intermediate warehousing links, and reduces labor and warehousing costs.

[0006] Furthermore, it also includes a first vertical circular tilting conveyor; the first vertical circular tilting conveyor includes several carriers and two correspondingly arranged first vertical closed circular tracks; the first vertical closed circular tracks extend from the cover forming and feeding mechanism to the unloading mechanism, and pass sequentially through the model feeding mechanism, the card feeding mechanism, and the packaging mechanism; the two ends of the carriers are respectively connected to the two first vertical closed circular tracks and are evenly distributed in the first vertical closed circular tracks; the carriers can move cyclically along the first vertical closed circular tracks; the carriers are provided with several cover receiving slots with upward openings; the cover forming and feeding mechanism places the cover in the cover receiving slots of the carriers. The vertical circular tilting conveyor integrates conveying and tilting functions, integrating multiple processes such as feeding and bonding into a compact conveyor line to be carried out simultaneously, forming a highly efficient production line and simplifying the flow path; the carriers rotate 180° and invert on the vertical closed circular tracks without stopping to change direction, resulting in high space utilization and a small footprint.

[0007] Furthermore, the plastic cover forming and feeding mechanism includes a heating device, a blow molding device, a film traction device, a plastic cover cutting device, a plastic cover feeding device, and a waste glue recycling device. The heating device is used to heat and soften the film. The blow molding device uses vacuum negative pressure to adsorb the preheated and softened film onto the mold surface to shape a plastic cover of the corresponding shape. The film traction device is used to drive the film to move. The plastic cover cutting device is used to cut the plastic cover off the film. The plastic cover feeding device grabs the cut plastic cover and moves it into the plastic cover receiving groove. The waste glue recycling device is used to simultaneously pull forward the waste plastic film after the plastic cover cutting is completed and to recycle the waste plastic film. This utility model provides a packaging equipment for models that combines the plastic cover preparation process, the plastic cover cutting process, and the waste glue recycling process into one operation, replacing manual labor with machinery to realize the mechanized production of plastic covers and greatly improve the production efficiency of plastic covers.

[0008] Furthermore, the waste adhesive recycling device includes a take-up rod, an auxiliary rod, a sensor, and a take-up motor; the waste adhesive sheet after the adhesive cover cutting is completed passes around the auxiliary rod and is connected to the take-up rod; when the waste adhesive sheet moves forward, the tension of the waste adhesive sheet on the auxiliary rod disappears, and the auxiliary rod moves away from the sensing area of ​​the sensor under the action of gravity. The sensor emits a sensing signal, and the take-up motor drives the take-up rod to rotate so that the waste adhesive sheet is wound around its rod body. At the same time, the waste adhesive sheet on the auxiliary rod regains its tension due to the end being taken back and pulls the auxiliary rod back to the sensing area of ​​the sensor. The take-up motor stops driving the take-up rod to rotate. This utility model discloses a packaging device for models that cleverly achieves mechanized recycling of waste film generated during the production of the model cover by using a waste glue recycling device. This eliminates the need for a separate recycling process using other equipment. Timely recycling of waste film avoids accumulation and prevents problems such as entanglement, obstruction, and damage to machinery and equipment.

More specifically, the cover forming and feeding mechanism 3 is located at the front end of the first vertical annular rotating conveyor 2, the model feeding mechanism 4 is located on one side of the front of the first vertical annular rotating conveyor 2, the card feeding mechanism 5 is located above the middle of the first vertical annular rotating conveyor 2, the packaging mechanism 6 is located above the tail of the first vertical annular rotating conveyor 2, and the unloading mechanism 7 is located at the tail end of the first vertical annular rotating conveyor 2. The cover forming and feeding mechanism 3 uses vacuum negative pressure to adsorb the preheated and softened film onto the mold surface to shape it into a cover, and then places the resulting cover on the first vertical annular rotating conveyor 2. The first vertical annular rotating conveyor 2 transports the cover sequentially through the model feeding mechanism 4, the card feeding mechanism 5, and the packaging mechanism 6 to the tail end of the first vertical annular rotating conveyor 2. The model feeding mechanism 4 places the model into the cover. The card feeding mechanism 5 covers the upper surface of the cover with card paper. The packaging mechanism 6 heat-presses the cardboard and the protective cover to obtain the packaged product. The unloading mechanism 7 picks up the packaged product from the tail end of the first vertical circular tilting conveyor 2 and moves it into the finished product box.

[0025] The first vertical circular tilting conveyor 2 includes several carriers 21, a first vertical main frame perpendicular to the ground, two first vertical closed circular tracks correspondingly arranged on the first vertical main frame, and a first conveying power device (not shown) providing power. The first vertical closed circular tracks extend from the cover forming and feeding mechanism 3 to the feeding mechanism 7, passing sequentially through the model feeding mechanism 4, the card feeding mechanism 5, and the packaging mechanism 6. The two ends of each carrier 21 are respectively connected to the two first vertical closed circular tracks and are evenly distributed in the first vertical closed circular tracks. The carrier can move cyclically along the first vertical closed circular tracks in sequence. Each carrier 21 is provided with several cover receiving slots 211 with upward openings. The cover forming and feeding mechanism 2 places the cover on the cover receiving slots 211. The first conveying power device drives the carrier 21 to move cyclically along the first vertical closed ring track in sequence, and the carrier 21 is sequentially conveyed to the plastic cover forming and feeding mechanism 3, the model feeding mechanism 4, the card feeding mechanism 5, the packaging mechanism 6, and the unloading mechanism 7.

[0026] Please see Figure 2 The film cover forming and unloading mechanism 3 includes a film roll unloading device 31, a film conveying auxiliary device 32, a film heating device 33, a blow molding device 34, a film traction device 35, a film cover cutting device 36, a film cover unloading device 37, and a waste glue recycling device 38. The film roll unloading device 31 is located in front of the frame 1; the film conveying auxiliary device 32, the film heating device 33, the blow molding device 34, the film traction device 35, the film cover cutting device 36, and the film cover unloading device 37 are sequentially arranged on the front part of the frame 1, and the film conveying auxiliary device 32 is located between the film roll unloading device 31 and the first vertical circular reversing conveyor 2.

[0027] The film unloading device 31 includes a fixed and rotatable film roller, on which the film roll is mounted. The film at one end of the film roll unfolds from the film roller and sequentially passes through the film conveying auxiliary device 32, the film heating device 33, the blow molding device 34, the film traction device 35, the film cover cutting device 36, and the waste film recycling device 38, completing processes such as film heating, film cover forming, film cover cutting, and waste film recycling. The film traction device 35 drives the film to move.

[0028] The film transport auxiliary device 32 is used to smoothly transport the film at one end of the film roll of the film unloading mechanism 1 to the film heating device 33. The film transport auxiliary device 32 includes several transport rollers for assisting the rolling of the film roll and several weight shafts (not shown) for maintaining the tension of the film. The transport rollers are horizontally arranged between the film unloading device 31 and the film heating device 33. The film roll passes around the transport rollers and connects to the film heating device 33. The weight shafts are placed on the film between two transport rollers to make the film bear the weight and maintain the tension, preventing the film from wrinkling, deviating or deforming, and ensuring that the film is flat.

[0029] The film heating device 33 is used to heat and soften the film; specifically, the film heating device 33 includes two horizontally opposite hot plates, through which the film passes horizontally and is heated and softened.

[0030] The blow molding device 34 utilizes vacuum negative pressure to adsorb preheated and softened plastic sheets onto the mold surface and shape them into a plastic cover of the corresponding shape. Specifically, the blow molding device 34 includes a fixed mold, a moving mold, a blow molding hydraulic press, and a vacuum system. The fixed mold and the moving mold are arranged opposite to each other; the moving mold has several plastic cover forming grooves recessed from its upper surface, and the plastic cover forming grooves are designed according to the shape and size of the plastic cover; the vacuum system is connected to the plastic cover forming grooves; the blow molding hydraulic press is connected to the moving mold and is used to drive the moving mold to move. The preheated and softened plastic sheet moves between the fixed mold and the moving mold, and the pressure rod of the blow molding hydraulic press pushes the moving mold to press against the surface of the fixed mold, so that the plastic cover forming grooves in the moving mold form a sealed space. The vacuum system evacuates the gas in the plastic cover forming grooves, so that the preheated and softened plastic sheet is adsorbed onto the surface of the plastic cover forming grooves, shaped and solidified to obtain the plastic cover; then the pressure rod of the blow molding hydraulic press pulls the moving mold away from the surface of the fixed mold. The film traction device 35 drives the film with several film cover structures to move to the film cover cutting device 36.

[0031] The film traction device 35 is used to drive the film forward and includes a horizontally arranged traction roller and a traction motor. The traction motor drives the traction roller to roll, and the friction between the surface of the traction roller and the film generates traction force to push the film forward. At the same time, it avoids the film from being subjected to eccentric tension during the traction process, which would cause uneven stress on the film, resulting in wrinkles, deviation, or stretching deformation, thus ensuring that the film is flat.

[0032] The cover cutting device 36 is used to cut the cover off the film. The cover cutting device 36 includes a punch, a die adapted to the punch, a cutting hydraulic press, and several cutting pressure bars. The punch includes several cutting blades distributed at its bottom, the distribution of which is designed according to the cutting edge of the cover; the die is located below the punch and includes several blanking holes corresponding to the cover for accommodating it; the cutting hydraulic press is connected to the die; the cutting pressure bars are located above the die and correspond one-to-one with the blanking holes, and can extend through the punch into the blanking holes. The film traction device 35 drives the film with the film cover structure to move between the punch and the die. The pressure rod of the cutting hydraulic press pushes the die to press against the surface of the punch. The cutting blade cuts the film cover from the film. After the cutting pressure rod knocks the film cover off the film, the film cover falls from the material discharge hole to the film cover discharge device 37.

[0033] The cover unloading device 37 is used to grab the cut-off covers and transfer them to the cover receiving slot 211 of the carrier 21 at the front end of the first vertical annular tilting conveyor 2. The cover unloading device 37 includes a movable cover transfer tray and a cover gripping device. The cover transfer tray is provided with a plurality of cover transfer receiving slots corresponding to the covers. The cover transfer tray moves to below the concave die of the cover cutting device 36, and the covers fall into the cover transfer receiving slots after being cut off from the film; the cover transfer tray moves out from below the concave die of the cover cutting device 36, and the cover gripping device grabs the covers from the cover transfer tray and transfers them to the carrier 21 at the front end of the first vertical annular tilting conveyor 2. Specifically, the cover gripping device 32 in this embodiment includes several cover gripping suction cups, cover gripping guide rods, and cover gripping crossbars for gripping covers using vacuum negative pressure. The two ends of the cover gripping guide rods are respectively positioned above the cover transfer tray and above the carrier 21 at the front end of the first vertical annular tilting conveyor 2. The cover gripping suction cups are positioned below the cover gripping crossbars, and each suction cup corresponds to a cover receiving groove in the carrier 21 at the front end of the cover forming and unloading mechanism 2. The cover gripping crossbars are movable along the crossbars. There are two cover gripping guide rods, arranged parallel to each other on both sides of the frame 1, and the two ends of the cover gripping crossbars are slidably connected to the cover gripping guide rods.

[0034] The waste adhesive recycling device 38 is used to recycle waste film after the film cover has been cut, and can operate in conjunction with the film traction device 35. The waste adhesive recycling device 38 is located above the front of the frame 1 and includes a horizontally arranged take-up rod 381 and auxiliary rod 382, ​​a sensor (not shown), and a take-up motor (not shown). The sensor is located on one side of the auxiliary rod 382 and is used to detect the state of the auxiliary rod 382; the output end of the take-up motor is connected to the take-up rod 381 and is used to drive the rotation of the take-up rod 381. The waste film after the film cover has been cut passes around the auxiliary rod 382 and is connected to the take-up rod 381. When the film is pulled forward by the film traction device 35, the tension of the waste film on the auxiliary rod 382 disappears. Under the action of gravity, the auxiliary rod 382 moves away from the sensing area of ​​the sensor. The sensor sends a sensing signal, and the take-up motor drives the take-up rod 381 to rotate, so that the waste film that has completed the film cover cutting is wound around its rod to complete the waste film winding and recycling. At the same time, the waste film on the auxiliary rod 382 regains its tension due to the winding and recycling of its end, and pulls the auxiliary rod 382 back to the sensing area of ​​the sensor. The sensor sends a sensing signal again, and the take-up motor stops driving the take-up rod to rotate. When the film traction device 35 drives the film forward again, the above steps are repeated to continuously complete the recycling of waste film. In this embodiment, the sensor and the take-up motor are electrically connected to the main control system. After the sensor sends a sensing signal to the main control system, the main control system controls the take-up motor to drive the take-up rod to rotate. In other embodiments, the sensor may also emit sensing signals in forms other than electrical signals, and the winding motor may also be controlled by other control systems.

[0035] The model feeding mechanism 4 is used to provide model raw materials and grab the model, placing it into the rubber cover in the carrier 21 in the middle of the first vertical circular tilting conveyor 2. The model feeding mechanism 4 includes a model feeding unit 42, a gripping unit 44, a transfer unit 46, and a feeding control system. The gripping unit 44 is used to grab the model and transfer it to the rubber cover on the carrier 21 in the middle of the first vertical circular tilting conveyor 2. The feeding control system controls the operation of the model feeding unit 42, the gripping unit 44, and the transfer unit, and is controlled by the overall control system. The gripping unit 44 includes a first gripping device 441 and a second gripping device 442. The first gripping device 441 grabs the model from the model feeding unit 42 and transfers it to the transfer unit 46. The second gripping device 442 grabs the model from the transfer unit 46 and transfers it to the rubber cover on the carrier 21 in the middle of the first vertical circular tilting conveyor 2.

The feeding device 423 includes several lifting columns, which can be controlled by the feeding control system 48 to pass through the bottom of the first transport device 422 and the model box 421 and gradually raise the bottom layer of the model box 421 and the model according to the settings, so that the models in the model box 421 reach the predetermined picking height position layer by layer. The identification device is located at the top of the model loading frame 425, above the loading device 423. The identification device includes a visual input camera, which is used to photograph the interior of the model material box 421 and transmit the photographed information to the feeding control system 48. After analysis and identification, the feeding control system 48 controls the first gripping device 441 to grab a model from the model material box 421 and move it to the transfer unit 46, or to grab an empty plastic sheet without a model from the model material box 421 and place it into the plastic sheet recycling box 424 located on one side. When the feeding control system 48 identifies that there are no models or plastic sheets to grab in the model material box 421, the lifting column descends below the model material box 421, and the double-row chain conveyor of the first transport device 422 moves the model material box 421 to the recycling area while simultaneously transporting the next model material box 421 loaded with a model to the top of the loading device 423, repeating the above feeding, identification, and gripping process.

[0037] Please see Figure 3The transfer unit 46 is used to adjust the model grabbed by the first gripping device 441 from the model feeding unit 42 to a vertical position suitable for secondary gripping or packaging. The transfer unit 46 includes a flipping carrier 461, a flipping device 462, several directional carriers 463, a second vertical annular flipping conveyor 464, and a transfer frame 465. The first gripping device 441, the second gripping device 442, the flipping carrier 461, the flipping device 462, the directional carrier 463, and the second vertical annular flipping conveyor 464 are all mounted on the transfer frame 465. The flipping carrier 461 is horizontally mounted on the flipping device 462 and has several model receiving slots arranged in sequence. The model receiving slots have openings on the side facing the directional carriers 463. The directional carriers 463 and the second vertical annular flipping conveyor 464 are located below the side of the flipping carrier 461 with the opening. The second vertical annular tilting conveyor 464 has its two ends guided below the tilting carrier 461 and the second gripping device 442, respectively, for conveying the directional carrier 463 and the model placed in the directional carrier 463 to the area below the tilting carrier 461 and the second gripping device 442. Specifically, the second vertical annular tilting conveyor 464 includes a second vertical main frame perpendicular to the ground, two second vertical closed annular tracks correspondingly arranged on the second vertical main frame, several conveying plates, and a second conveying power device providing power. The two ends of the second vertical closed annular tracks are guided below the tilting carrier 461 and the second gripping device 442, respectively.

The conveying plates are evenly distributed between the second vertical closed annular tracks and can move cyclically along the second vertical closed annular tracks in sequence. The orientation carrier 463 is disposed on the upper surface of the conveyor plate and has an upward-opening positioning groove, which corresponds one-to-one with the model receiving groove of the flipping carrier 461. The flipping device 462 raises the side of the flipping carrier 461 without an opening, causing the model in the flipping carrier 461 to slide out from the opening and fall vertically into the positioning groove of its nearest orientation carrier 463.

[0038] After the first gripping device 441 grips the model from the model bin 421, it places the model in the model receiving slot of the flipping carrier 461. The flipping device 462 flips the flipping carrier 461 so that the model slides out from the opening and falls vertically into the positioning slot of the nearest directional carrier 463. The directional carrier 463 carrying the model and its conveyor plate move along the second vertical closed loop track toward the second gripping device 442. At the same time, the empty directional carrier 463 and its conveyor plate move along the second vertical closed loop track toward the underside of the flipping carrier 461. Repeating the above steps can continuously transfer the model from the model bin 421 to the positioning slot of the directional carrier 463 in the transfer unit 46. In this embodiment, the first gripping device 441 adopts a common industrial robotic arm, including several vacuum suction cups that correspond one-to-one with the model receiving slots of the flipping carrier 461. The vacuum suction cups move to several model upper surfaces of the model box 421 and use vacuum negative pressure to grip the models respectively, and then move them above the model receiving slots of the flipping carrier 461 to release the models into the model receiving slots. In other embodiments, the first gripping device 441 can use other industrial gripping machinery.

[0039] The second gripping device 442 grips the vertically positioned model from the positioning slot of the directional carrier 463 in the transfer unit 46 and moves it into the rubber cover in the first vertical annular tilting conveyor 2. The second gripping device 442 includes a gripping lateral movement assembly 4422, a gripping vertical movement assembly 4424, and a gripper assembly 4426. The gripping lateral movement assembly 4422 and the gripping vertical movement assembly 4424 work together to move the gripper assembly 4426. The gripping lateral movement assembly 4422 includes a horizontal gripping guide rail, a horizontal moving platform that can move along the horizontal gripping guide rail, and a horizontal servo motor that drives the horizontal moving platform to move along the horizontal gripping guide rail. The two ends of the horizontal gripping guide rail are respectively guided above the directional carrier 463 carrying the model and above the carrier 21 carrying the rubber cover in the middle of the first vertical annular tilting conveyor 2. The gripper vertical movement assembly 4424 is disposed on the horizontal moving platform and located on the side facing the transfer unit 46. The gripper vertical movement assembly 4424 includes a vertical gripper guide rail, a vertical moving platform movable along the vertical gripper guide rail, a vertical ball screw pair, and a vertical servo motor. The vertical servo motor drives the vertical ball screw pair to rotate via a coupling, thereby driving the vertical moving platform to rise and fall along the vertical gripper guide rail. The gripper assembly 4426 includes a gripper carrier and several pneumatic grippers. The gripper carrier is disposed at the lower part of the vertical moving platform. The pneumatic grippers are disposed and connected below the gripper carrier. The pneumatic grippers are driven by cylinders, and the opening / closing of the grippers is achieved by controlling the on / off of compressed air through a solenoid valve. The horizontal moving component 4422 moves the vertical moving component 4424 and the gripper component 4426 above the directional carrier 463 containing the model. The vertical moving component 4424 moves the pneumatic gripper down to the model in the positioning slot of the directional carrier 463. After the pneumatic gripper grabs the model, the vertical moving component 4424 moves the pneumatic gripper up away from the directional carrier 463. The horizontal moving component 4422 moves the vertical moving component 4424 and the grabbed model above the carrier 21 with a rubber cover in the middle of the first vertical annular tilting conveyor 2. The vertical moving component 4424 moves the pneumatic gripper downwards, releasing the model it has grasped into the rubber cover of the carrier 21. Then, the vertical moving component 4424 moves the pneumatic gripper upwards away from the carrier 21. The horizontal moving component 4422 moves the vertical moving component 4424 and the gripper component 4426 above the directional carrier 463 containing the model. Repeating these steps continuously completes the process of grasping the vertically positioned model from the positioning slot of the directional carrier 463 in the transfer unit 46 and moving it into the rubber cover in the first vertical annular tilting conveyor 2. In this embodiment, the pneumatic gripper and the directional carrier 463 are arranged in a one-to-one correspondence.Furthermore, the gripper assembly 4426 also includes an airflow divider block, under the action of the airflow divider block, all the pneumatic grippers synchronously complete the opening or closing action to grip or release the model. Further, in other embodiments, the second gripping device 442 also includes a steering assembly that can drive the pneumatic gripper to rotate horizontally to adjust the orientation of the model gripped by the pneumatic gripper, used to adjust the state of the model gripped by the pneumatic gripper placed in the rubber cover in the first vertical annular tilting conveyor 2.
