Description

Technical Field

[0001] This utility model relates to the field of automatic packaging equipment technology, and in particular to an automatic plastic tray placement machine. Background Technology

[0002] Currently, in the packaging equipment used in China, plastic pallets are generally placed manually. Due to the wide variety of shapes and sizes of plastic pallets, the plastic pallet placement machine has not achieved automation. The manual placement of plastic pallets not only occupies space and labor, but also seriously affects production efficiency and inevitably leads to missed placements.

[0003] With societal development and rising business demands, automatic pallet placing mechanisms have emerged to reduce labor intensity. For example, Chinese invention patent CN 108394596 B discloses a fully automatic top-plate placement device for flat paper packaging lines. This device uses a rodless cylinder to drive a four-sided straightening device to align the top plate with the paper stack; a motor-driven gear system to move a rack and pinion up and down to lift the top plate adsorption mechanism; a motor-driven pulley system with synchronous belt traction to move the vertical lifting device horizontally; and a vacuum generator to lift the top plate. Through the coordination of these mechanisms and a supporting conveying system, the fully automatic top-plate placement device achieves continuous online packaging.

[0004] In this structure, the top cover is first placed on the paper stack surface and then the alignment is adjusted. However, for automatic palletizing of cardboard boxes, if the alignment is not adjusted in advance, the cardboard boxes cannot be placed. Therefore, the existing palletizing device needs to be structurally optimized to meet the needs of automatic palletizing of cardboard box packaging materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic plastic tray placement machine that automatically places plastic trays into cardboard packaging materials, reducing manual labor intensity and costs, preventing omissions or misplacements, and improving work efficiency.

[0006] The technical solution to achieve the purpose of this utility model is:

[0007] An automatic plastic tray placement machine includes a frame and a plastic tray storage platform located at the bottom of the frame. The plastic tray storage platform has symmetrically arranged adjustable-space plastic tray limiting plates on both sides, forming a first tray feeding channel. The first tray feeding channel is equipped with a reciprocating pusher mechanism, and at its end is a plastic tray transfer section and a box conveying section. The pusher mechanism is adapted to move the plastic trays stacked in the first tray feeding channel to the plastic tray transfer section, and then the plastic tray transfer section delivers them one by one to the box conveying section. The box conveying section has a box feeding channel horizontally arranged perpendicular to the first tray feeding channel, and symmetrically arranged on both sides along the box conveying direction are a box blocking mechanism and a box clamping mechanism. The box clamping mechanism is used to clamp the conveyed boxes.

[0008] Furthermore, the plastic tray transfer section includes a lifting plate section that can be raised and lowered, and a transfer plate section that is suspended on the top of the frame and can be moved horizontally along the first plate feeding channel. The transfer plate section is provided with a suction cup module that can be raised and lowered.

[0009] Furthermore, it also includes a baffle mechanism arranged opposite to each other, the baffle mechanism including a baffle cylinder fixedly mounted on the top of the plastic tray limiting plate, the piston rod of the baffle cylinder being fixedly connected to an insert block that can be inserted between the top plastic tray and the second-to-top plastic tray of the plastic tray stack.

[0010] Furthermore, a vertically arranged linear module is fixedly mounted on the frame, and the lifting plate includes a base fixed on the movable block of the linear module and a lifting plate fixed on the top of the base.

[0011] Furthermore, a translation cylinder and a pair of guide rod assemblies arranged parallel to the translation cylinder are fixedly mounted on the top of the frame. The moving plate part includes a horizontal plate fixed on the sliding block of the guide rod assembly. A connecting seat is fixedly connected between the horizontal plate and the piston rod end of the translation cylinder.

[0012] Furthermore, a lifting cylinder is fixedly mounted on the moving plate section. The piston rod of the lifting cylinder is vertically downward and connected to a floating joint. The suction cup module includes a top plate fixedly connected to the floating joint. Multiple vacuum nozzles are fixedly mounted on the top plate. A pressure plate that is elastically connected to the top plate is arranged parallel below. The vacuum nozzles are arranged through the pressure plate and the distance between the bottom of the nozzle and the pressure plate is less than the thickness of the plastic tray.

[0013] Furthermore, a pair of guide rods are fixedly mounted parallel to each other below the plastic tray storage platform. An adjustable first adjustment block is provided at the upper limit of the guide rods. A push plate cylinder is fixedly mounted on the first adjustment block, and a second adjustment block is slidably mounted on the guide rod near the entrance side of the first plate feeding channel. The push plate mechanism is a first push plate frame that is vertically fixed on the second adjustment block. The second adjustment block is fixedly connected to the piston rod of the push plate cylinder.

[0014] Furthermore, a lead screw is provided below the plastic tray storage platform, parallel to the two guide rods. A third adjustment block is slidably mounted on the guide rod on the side of the first adjustment block away from the entrance of the first feeding channel. A second push plate frame is vertically fixed on the third adjustment block. The first adjustment block and the third adjustment block are respectively sleeved on the lead screw through positive and negative thread engagement. The two sides of the plate shifting part are provided with notches that are adapted to the first push plate frame and the second push plate frame.

[0015] Furthermore, a guide section is provided on the side of the box conveying section away from the plastic tray storage platform. The guide section includes a liftable and adjustable crossbar. Mounting plates are symmetrically provided at both ends of the crossbar. Miniature cylinders and rotating shafts are rotatably provided at both ends of the mounting plates. The piston rod of the miniature cylinder is rotatably provided with a drive rod fixedly connected to the rotating shaft. A pair of guide plates inserted into the box are fixedly connected to the rotating shaft. The guide plates form a second feeding channel suitable for the plastic tray to pass through.

[0016] Furthermore, the guide plate includes a first plate and a second plate connected together with an obtuse angle. When the guide plate is in the first state, the first plate is horizontally positioned. When the guide plate is in the second state, the first plate is inclined in the vertical direction to form a second feeding channel that is larger at the top and smaller at the bottom.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] (1) This utility model limits the plastic pallet stacking and the box body by using a plastic pallet limiting plate and a box clamping mechanism respectively, so as to ensure that the plastic pallet and the box body can maintain a fixed relative position before assembly. By pre-setting the position, the plastic pallet can be accurately and automatically placed into the carton under the action of the plastic pallet transfer part, reducing the intensity and cost of manual labor, avoiding omissions or misplacements, and improving work efficiency.

[0019] (2) This utility model lifts the plastic trays upward by lifting the lifting plate, and the suction cup module holds the plastic trays on the top of the stack and moves them to the box conveying part to complete the transfer of the plastic trays. The structure is simple.

[0020] (3) By setting up a baffle mechanism consisting of a baffle cylinder and an insert block, the first plastic tray and the second plastic tray are separated from top to bottom, thus preventing multiple plastic trays from being sucked away at once.

[0021] (4) By setting up a second feeding channel surrounded by a guide plate, the upper part of the box is opened after the box is delivered to the position, so as to avoid interference and allow the plastic tray to be smoothly placed into the box.

[0022] (5) This utility model uses a linear module to drive the lifting plate to rise and fall, which can accurately control the distance of each rise, ensuring that the waiting transfer position of the plastic tray is fixed. At the same time, cylinders are used to realize the translation of the plate-moving part and the lifting of the suction cup module respectively. The structure is simple, the action response is fast, and the overall packaging efficiency is improved.

[0023] (6) The suction cup module of this utility model is equipped with a pressure plate that is elastically connected to the top plate. By controlling the distance between the pressure plate and the bottom of the vacuum nozzle, the pressure plate receives a slight upward pressure after the vacuum nozzle adsorbs the plastic tray, and thus receives a downward elastic force when the vacuum is broken, so that the plastic tray can be completely separated from the vacuum nozzle, thereby improving the transfer success rate.

[0024] (7) This utility model uses a push plate cylinder to push the second adjusting block to realize the reciprocating motion of the push plate mechanism. The structure is simple, the action response is fast, and the overall packaging efficiency is improved.

[0025] (8) This utility model achieves the mutual approach or distance of two adjusting blocks by rotating the screw, thereby adjusting the initial distance between the two push plate frames, thus meeting the limiting requirements of plastic trays of different sizes, and has better versatility.

[0026] (9) The guide plate of this utility model is made of two flat plates connected at an obtuse angle. When the plastic tray is not lowered, the guide plate is placed horizontally, thereby forming a barrier between the box and the plastic tray to prevent the plastic tray from falling accidentally. When the plastic tray is lowered, the guide plate is flipped to be tilted downward, making the entrance of the second feeding channel larger and making it easier to guide the plastic tray into the box.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] (Example 1)

[0039] like Figures 1 to 7 The automatic plastic pallet loading machine shown includes a frame 1, a plastic pallet storage platform 2, plastic pallet limiting plates 3, a pusher mechanism 4, a plastic pallet transfer section 5, and a box conveying section 6. The plastic pallet storage platform 2 is located at the lower part of the frame 1 and is used to store and stack plastic pallets. Two plastic pallet limiting plates 3 are symmetrically arranged, with adjustable spacing on both sides of the plastic pallet transfer section 5, forming a first feeding channel for limiting the front and rear sides of the plastic pallet stack. The pusher mechanism 4 is reciprocatingly located within the first feeding channel. The plastic pallet transfer section 5 and the box conveying section 6 are sequentially located at the end of the first feeding channel. Initially, the pusher mechanism 4 is located on the left side of the plastic pallet stack, used to push the stack to the right onto the plastic pallet transfer section 5. The plastic trays are transferred one by one by the material tray transfer unit 5 to the box conveying unit 6. The box conveying unit 6 is set horizontally perpendicular to the first plate conveying channel, and the box blocking mechanism 7 and the box clamping mechanism 8 are symmetrically arranged on both sides along the box conveying direction. The box blocking mechanism 7 blocks the subsequent box conveying, and the box clamping mechanism 8 clamps the conveyed box to limit the box. This ensures that the plastic trays can be accurately and automatically placed into the carton under the action of the plastic tray transfer unit 5, reducing the intensity and cost of manual labor, avoiding omissions or misplacements, and improving work efficiency.

[0040] Specifically, the box conveying section 6 is a roller conveyor. Adjustable guardrails 9 are installed on both sides of the roller conveyor via a combination of slotted grooves and screws. A box-blocking mechanism 7 and a box-clamping mechanism 8 are mounted on the guardrails along the conveying direction. These mechanisms employ cylinder-driven structures for rapid response. When conveying boxes of different sizes, simply changing the spacing of the guardrails 9 allows for universal operation.

[0041] A pair of guide rods 10 are fixedly mounted parallel to each other below the plastic tray storage platform 2. A lead screw 11 is arranged parallel between the two guide rods 10. A first adjusting block 12 and a third adjusting block 13 are slidably mounted on the guide rods 10 through a positive and negative thread engagement on the lead screw 11, so that when the lead screw 11 is rotated, the two first adjusting blocks 12 and the third adjusting blocks 13 move closer or further apart. A push plate cylinder 14 is fixedly mounted on the first adjusting block 12, and a second adjusting block 15 is slidably mounted on the guide rods 10 on the left side. The push plate mechanism 4 is a first push plate frame that is vertically fixed on the second adjusting block 15. The plastic tray storage platform 2 has a through groove that is adapted to the first push plate frame, and the first push plate frame is set through the through groove. A second push plate frame 16 that is vertically fixed on the third adjusting block 13 and is arranged opposite to the first push plate frame. The two push plate frames limit the left and right sides of the plastic tray stacking, realize the stacking and alignment, and ensure the accurate position of the plastic trays. The second adjusting block 15 is fixedly connected to the piston rod of the push plate cylinder 14, thereby driving the push plate mechanism 4 on it to reciprocate and realize the function of pushing plastic pallets for stacking. By setting the first adjusting block 12 and the third adjusting block 13 with adjustable spacing, the initial spacing adjustment of the push plate cylinder 14 and the second push plate frame 16 is realized, thereby realizing the initial spacing adjustment between the push plate mechanism 4 driven by the push plate cylinder 14 and the second push plate frame 16, thus satisfying the length direction limit of plastic pallets of different sizes.

[0042] The plastic pallet transfer unit 5 includes a lifting plate part 5-1 located between the push plate mechanism 4 and the second push plate frame 16 and which can be raised and lowered; a moving plate part 5-2 suspended on the top of the frame 1 and movable along the first feeding channel; and a suction cup module 5-3 raised and lowered on the moving plate part 5-2. Specifically, a vertically arranged straight line module 5-4 is fixedly provided on the frame 1. The lifting plate part 5-1 includes a base 5-1-1 fixed on the moving block of the straight line module 5-4 and a lifting plate 5-1-2 fixed on the top of the base 5-1-1. The lifting plate 5-1-2 has notches on both sides that are adapted to the first push plate frame and the second push plate frame to meet the requirements of stacking smaller plastic pallets. The top of the frame 1 is fixedly equipped with a translation cylinder 5-5 and a pair of guide rod assemblies 5-6 arranged parallel to the translation cylinder 5-5. The moving plate part 5-2 includes a horizontal plate fixedly mounted on the sliding block of the guide rod assembly 5-6. A connecting seat 5-7 is fixedly connected between the horizontal plate and the piston rod end of the translation cylinder 5-5. A lifting cylinder 5-8 is fixedly mounted on the horizontal plate. The piston rod of the lifting cylinder 5-8 is arranged vertically downward and connected to a floating joint. The suction cup module 5-3 includes a top plate 5-3-1 fixedly connected to the floating joint. Multiple vacuum nozzles 5-3-2 are fixedly mounted on the top plate 5-3-1. A pressure plate 5-3-3 arranged parallel to the top plate 5-3-1 is connected below by a hanger and a spring, realizing an elastic connection between the pressure plate 5-3-3 and the top plate 5-3-1. The vacuum nozzles 5-3-2 are arranged through the pressure plate 5-3-3, and the distance between the bottom of the nozzles and the pressure plate 5-3-3 is slightly less than the thickness of the plastic support. By controlling the distance between the pressure plate 5-3-3 and the bottom of the vacuum nozzle 5-3-2, after the vacuum nozzle 5-3-2 adsorbs the plastic tray, the pressure plate 5-3-3 receives a slight upward pressure, which in turn generates a downward elastic force when the vacuum is broken, allowing the plastic tray to completely separate from the vacuum nozzle and improving the transfer success rate.

[0043] To prevent the vacuum nozzle 5-3-2 from simultaneously picking up two plastic trays due to excessive suction when adsorbing plastic trays, this embodiment also provides a baffle mechanism 17 arranged opposite to each other. The baffle mechanism 17 includes a baffle cylinder 17-1 fixedly mounted on the top of the plastic tray limiting plate 3. The piston rod of the baffle cylinder 17-1 is fixedly connected to an insert block 17-2 that can be inserted between the top plastic tray and the next top plastic tray in the plastic tray stack, thereby effectively separating adjacent plastic trays and preventing them from sticking together.

[0044] To facilitate the smooth entry of the plastic tray into the box, this embodiment provides a guide section 18 on the right side of the box conveying section 6. The guide section 18 includes a horizontal bar 18-1 that is adjustable in height via a handwheel screw assembly. Mounting plates 18-2 are symmetrically arranged at both ends of the horizontal bar 18-1. Miniature cylinders 18-3 and rotating shafts 18-4 are rotatably mounted at both ends of the mounting plates 18-2. The piston rod of the miniature cylinder 18-3 is rotatably connected to a drive rod 18-5 that is fixedly connected to the rotating shaft 18-4. A pair of guide plates 18-6 that are inserted into the box are fixedly connected to the rotating shaft 18-4. The four guide plates form a second feeding channel suitable for the passage of the plastic tray, preventing interference with the upper part of the box. The guide plate 18-6 includes a first plate and a second plate connected together with an obtuse angle. When the guide plate 18-6 is in the first state under the action of the micro cylinder 18-3, the first plate is horizontally set, forming a barrier between the box and the plastic tray when the plastic tray has not descended, to prevent the plastic tray from falling accidentally. When the guide plate 18-6 is in the second state, the first plate is inclined in the vertical direction to form a second feeding channel that is larger at the top and smaller at the bottom, which makes it easier to guide the plastic tray into the box.

[0045] This invention uses a plastic tray limiting plate 3 and a box clamping mechanism 8 to limit the stacking of plastic trays and the box body, respectively, thereby ensuring that the plastic trays and the box body can maintain a fixed relative position before assembly. By pre-setting this position, it is ensured that the plastic trays can be accurately and automatically placed into the carton under the action of the plastic tray transfer part 5, reducing manual labor intensity and cost, avoiding omissions or misplacements, and improving work efficiency.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
