Description

Technical Field

[0001] This invention relates to the field of cardboard box production technology, specifically to a cardboard box palletizing device. Background Technology

[0002] Cardboard boxes are packaging containers made of corrugated cardboard. They are characterized by low cost, light weight, easy processing, and recyclability. Palletizers are automated stacking equipment after cardboard box production. They are usually composed of robotic arms, conveying systems, and control systems. Through sensors and programs, they can accurately locate and grab cardboard boxes, and stack them neatly according to the set arrangement and number of layers, improving production efficiency and reducing manual labor intensity.

[0003] Traditional cardboard box palletizing relies on robotic arms, which typically handle individual boxes for palletizing. This process involves multiple transfers by the robotic arm, wasting time. Furthermore, the robotic arm usually follows a preset program, making it impossible to assess center of gravity shifts and interlayer friction in real time, leading to boxes tipping over after palletizing. The multiple independent stacking of boxes can also cause uneven spacing and messy stacking. In addition, the robotic arm requires precise placement of the pallet, necessitating manual adjustment. Therefore, we propose a cardboard box palletizing device that adapts to different sized boxes, allowing multiple boxes to be aligned and then stacked onto precisely positioned pallets to address these shortcomings of existing technology. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a carton palletizing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a carton palletizing device, including a roller conveyor, and further comprising,

[0019] Furthermore, the locking element includes:

[0020] A locking groove is provided on the upper surface of the adjusting rod;

[0021] A nut is located at the upper end of the sliding sleeve, and a locking screw is internally threaded onto the nut. The locking screw passes through the sliding sleeve and is located in the locking groove.

[0022] Furthermore, the switching assembly includes:

[0023] An L-shaped frame is located at the upper rear end of the roller conveyor. The rear surface of the L-shaped frame is provided with multiple guide slide rods. A movable slide block slides on the outside of the guide slide rods, and the movable slide block is connected to the switch plate.

[0024] Linear electric guide rail one is also located at the upper rear end of the roller conveyor, and the guide rail slide of linear electric guide rail one is connected to the switch plate through a support connecting rod.

[0025] Furthermore, the pushing assembly includes a second hydraulic push rod located at the lower middle part of the support frame, a second linear electric guide rail vertically downward at the push rod of the second hydraulic push rod, and the guide rail slide of the second linear electric guide rail connected to the push plate.

[0026] Furthermore, the adjustment component includes an adjustment hole extending vertically through the loading seat, through which the suction cup seat passes, and a locking nut threaded onto the external surface of the suction cup seat, the locking nut being fitted against the upper surface of the loading seat.

[0027] Furthermore, the lower end of the movable seat is provided with a track wheel that rolls within the linear electric track.

[0028] Furthermore, the vacuum assembly includes a vacuum pump located at the front of the loading seat, an air pipe connected to the air intake of the vacuum pump, and a flexible hose connected between the air pipe and the suction cup seat.

[0029] The hose has an external connection with an automatic on / off valve.

[0030] Furthermore, the positioning and locking assembly includes an adjustment groove located at the upper left end of the movable seat, a pair of L-shaped positioning blocks sliding in the adjustment groove, and a threaded locking rod threadedly connected to the upper end of the L-shaped positioning blocks, the threaded locking rod fixing the L-shaped positioning blocks in the adjustment groove.

[0032] Furthermore, the left side of the switch plate is flush with the left inner wall of the L-shaped positioning block, and the left end of the switch plate is in contact with the right end of the roller conveyor.

[0033] Compared with the prior art, the present invention provides a carton palletizing device with the following advantages:

[0034] 1. This carton palletizing equipment, based on the length and width of the pallet, adjusts the positioning and locking components on the moving seat to position the pallet on the moving seat, ensuring that the left and right sides of the pallet are aligned with the left side of the switch plate and the left side of the limit rod, respectively. Simultaneously, a linear electric track drives the moving seat, moving the pallet. This facilitates automatic adjustment and movement when subsequent cartons are stacked orderly on the pallet, avoiding the need for manual pallet placement and adjustment by a robotic arm, thus improving the accuracy and efficiency of pallet placement and ensuring the flatness of subsequent carton stacking.

[0035] 2. This carton palletizing equipment, based on the length or width of the bundled cartons, and supported by a support frame, adjusts the guide rods based on the middle of the roller conveyor by adjusting the locking components on the adjusting rods. This ensures that the width of the space between the guide rods is equal to the length or width of the bundled cartons. Additionally, an electric push rod moves a limiting rod within a sliding hole, aligning the left side of the limiting rod with the right side of the pallet. The sliding groove ensures that the movement and adjustment of the guide rods are not affected. This allows the roller conveyor to sequentially transport the bundled cartons into the space between the guide rods for mutual bonding and assembly until the wide sides of the assembled cartons are aligned with the long sides of the pallet. A switch plate lifts the assembled cartons. After bonding, a pushing component moves the push plate vertically and horizontally to compress the assembled cartons, ensuring a tight bond between them.

[0036] In addition, depending on the position of the carton, the suction cup seats on the adjusting component are moved so that the suction cup seats are respectively located above the assembled carton. With the help of the hydraulic push rod, the loading seat, suction cup seats and suction cups are pushed down so that the suction cups on each suction cup seat are respectively attached to each assembled carton. The vacuum component works to achieve the suction cups adsorb and fix the carton.

[0037] When stacking combined cartons on the pallet, a switch assembly separates the switch plate from the guide rod, and a hydraulic push rod moves the adsorbed combined cartons up and down. A linear electric track moves the pallet to adjust its position, allowing the cartons to be stacked layer by layer on the pallet. This enables the positioning and alignment of cartons of different sizes. After multiple cartons are attached, stacked, and positioned to ensure flatness, the automatic movement and adjustment of the pallet allows the cartons to be stacked in an orderly manner. This avoids the need for a robotic arm to transfer and stack cartons multiple times, improving stacking efficiency and the flatness of the stacked cartons. Attached Figure Description

[0087] Start the electric push rod 20 to push the limit rod 18 to move within the sliding hole 17, so that the left side of the limit rod 18 is aligned with the right side of the card plate 41.

[0088] Adjust the position of the suction cup seat 24 in the adjustment hole 23 according to the size of the bundled cartons, so that the suction cup seat 24 is positioned above each bundled carton after bonding. After adjustment, tighten the locking nut 25 to fix the suction cup seat 24 on the loading seat 22.

[0089] Equipment operation

[0090] Start the roller conveyor 1 to transport the bundled cartons sequentially into the Y-shaped space formed between the guide rods 10, so that the bundled cartons are attached and spliced ​​together in the space formed by the guide rods 10, and the switch plate 14 lifts the bundled cartons.

[0091] When the length of the assembled bundled cartons is equal to the width of the lower cardboard plate 41, the linear electric guide rail 31 is activated to move the push plate 32 downward. Then, the hydraulic push rod 30 is activated to push the push plate 32 to move and squeeze the assembled bundled cartons to make them fit tightly together.

[0092] Start the hydraulic push rod 21 to push the loading seat 22, suction cup seat 24 and suction cup 26 down, so that the suction cup 26 on each suction cup seat 24 fits against the upper surface of each bundled carton.

[0093] Start the vacuum pump 27. Through the interconnection between the vacuum pump 27, air pipe 28, suction cup seat 24 and suction cup 26, a vacuum process is performed, so that the suction cup 26 can adsorb and fix the bundled carton.

[0094] Start the linear electric guide rail 15, which drives the switch plate 14 on the support rod 16 to move, and simultaneously drives the movable slide block 13 to move in a directional manner outside the guide slide rod 12, so that the switch plate 14 moves and separates from the guide rod 10.

[0095] Continue to activate hydraulic push rod 21 to push loading seat 22 down, causing the bundled cartons to move down synchronously. At the same time, activate linear electric track 33 to drive moving seat 35 to move under the rolling action of track wheel 34, automatically adjust the position of pallet 41, and stack the bundled cartons on the surface of pallet 41 in sequence. By controlling the pushing distance of hydraulic push rod 21, the bundled cartons can be stacked layer by layer.

[0096] After the cartons are stacked, activate hydraulic push rod 39 to separate positioning push plate 40 from pallet 41, allowing pallet 41 to be transferred by forklift.

[0097] Principles and beneficial effects:

[0098] principle,

[0099] This equipment adjusts the spacing of the guide rods 10 to achieve the positioning and combination of bundled cartons of different sizes, so that the cartons fit together and are spliced ​​between the guide rods 10.

[0100] The switch plate 14 is used to lift the assembled cartons, and the pusher component is used to squeeze the assembled cartons to ensure that the cartons fit tightly together.

[0101] By adjusting the position of the suction cup seat 24, the suction cup 26 can accurately adsorb the assembled cardboard box, and the vacuum assembly enables the suction cup 26 to firmly adsorb the cardboard box.

[0102] The switch assembly controls the opening and sealing of the switch plate 14 to release the carton assembly. The linear electric track 33 drives the pallet 41 to move, and in conjunction with the hydraulic push rod 21, the cartons are stacked layer by layer.

[0103] Beneficial effects

[0104] Adaptable to different sized cartons: By adjusting the spacing of the guide rods 10 and the position of the suction cup seat 24, it can adapt to cartons of different lengths and widths for positioning, combination and alignment, improving the versatility and flexibility of the equipment.

[0105] Ensuring flatness of the assembly: The pushing component squeezes the assembled cartons, making them fit tightly together and ensuring the flatness of the carton assembly, which is beneficial for subsequent stacking operations.

[0106] Improved stacking efficiency: Avoiding the single and multiple transfers and stacking of cartons by the robotic arm, the rapid layer-by-layer stacking of cartons is achieved by automatically adjusting the position of the pallet 41 and the movement of the hydraulic push rod 21, thereby improving stacking efficiency and stacking flatness.

[0107] Improved pallet placement accuracy: The positioning and locking assembly can accurately position the pallet 41 on the moving base 35, ensuring that the left and right sides of the pallet 41 are aligned with the left side of the switch plate 14 and the left side of the limit rod 18, respectively, thus improving the accuracy of the pallet placement position and ensuring the flatness of the carton stacking.

[0108] This equipment can be equipped with a complete control system, using a programmable logic controller (PLC) as the core control unit. The control system mainly performs the following functions:

[0109] Equipment start and stop control: The operation and stop of the entire equipment can be controlled by the start and stop buttons on the operation panel.

[0110] Parameter setting and adjustment: Operators can set parameters such as the spacing of guide rods 10, the position of suction cup seat 24, the squeezing force, and the number of stacking layers on the control panel. The control system will automatically adjust the operation of each component of the equipment according to the set parameters.

[0111] Sensor monitoring and feedback: Sensors such as carton position sensors, pressure sensors, and vacuum sensors are installed in key parts of the equipment. The carton position sensor is used to detect the position of the carton on the roller conveyor 1 to ensure that the carton is accurately conveyed between the guide rods 10. The pressure sensor is used to monitor the squeezing force of the pushing component on the carton to avoid excessive squeezing force that could damage the carton. The vacuum sensor is used to monitor the vacuum level of the suction cup 26 to ensure that the suction cup 26 firmly adheres to the carton. The sensors feed back the detected signals to the control system, and the control system adjusts and controls according to the feedback signals.
