Description

Technical Field

[0001] This application relates to the field of depalletizers, and more specifically, to an intelligent depalletizer for material bag pallets. Background Technology

[0002] In the process of material transfer and storage, considering space utilization and ease of access, most bagged materials in the industry are currently stacked in multiple layers. Therefore, destacking is required during transfer or retrieval. Existing destacking equipment is mostly suitable for palletized mobile stacks, requiring the use of transfer tools to move the entire stack of materials, along with the pallet, to the destacking equipment for destacking. However, in most warehouses or freight vehicles, materials are fixed stacks directly on the ground, and pallets cannot be moved. Therefore, destacking can only be done manually, resulting in high labor intensity and poor working conditions for workers. For the transfer of fixed stacks of materials in warehouses or freight vehicles, space constraints and feasibility must also be considered. In addition, existing non-palletized depalletizing equipment often requires a robotic arm to grab the bagged materials and then work with a conveyor belt to depalletize them. The robotic arm is often complex in structure and needs to be set up separately. Moreover, the clamping force is not easy to control. If the clamping force is too low, it may cause problems such as unstable clamping and bags falling off. If the clamping force is set too high, it may damage the bags or the materials inside the bags. Using a forklift method makes it difficult to ensure that the insertion position is in the gap between the bags, which may push the stacked bags over and cause danger.

[0003] Therefore, an intelligent depalletizer for material bag pallets is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide an intelligent depalletizing machine for material bag trays, comprising: a vertical assembly and a base, the base being fixed to the lower end of the vertical assembly, with anchor fastening devices for fixing to the ground at the four corners of the base; a material bag tray seat, disposed on the rear side of the vertical assembly and sliding vertically on the vertical assembly, for placing material bag trays; a telescopic conveyor line, disposed on the vertical assembly, for inserting into the lower side of the uppermost layer of material bags and depalletizing sequentially from bottom to bottom; a stacking baffle, installed on the vertical assembly and located above the material bag tray seat, for blocking and limiting the material bags; the telescopic conveyor line includes: a telescopic line bracket, an upper conveyor line, a lower conveyor line, a bag-blocking mechanism, and a material picker; The telescopic support bracket is fixed to the upright assembly and is used to install the upper and lower conveyor lines. The lower conveyor line is fixedly mounted on the telescopic support bracket, and the upper conveyor line is slidably mounted on the telescopic support bracket. The upper and lower conveyor lines are arranged vertically, and their transport directions are the same. The upper conveyor line slides backward to transport the bags on the bag tray seat forward. The bag-blocking mechanism is movably mounted on the upper conveyor line to limit the bags and prevent damage. The material picker is rotatably mounted on the upper conveyor line to lift the bags onto the upper conveyor line. The bag-blocking mechanism includes a mounting frame mounted on the upper conveyor line, a deflector frame rotatably connected to the mounting frame, a spring between the deflector frame and the mounting frame, and a pressure roller rotatably connected to the deflector frame.

[0006] The bag tray seats, when raised and lowered, transport the bags to the telescopic conveyor line. The telescopic conveyor line then unpacks the bags sequentially. An upper and lower conveyor line, with its retractable movement, places the bags from the trays onto the upper conveyor line, which then moves the bags forward for unpacking. A bag-blocking mechanism and a material picker ensure that when the upper conveyor line moves backward, the picker lifts the topmost bag onto the line, preventing damage caused by difficulty in inserting the material picker. Springs apply pressure to the bags, keeping them pressed firmly against the upper conveyor line and preventing slippage. A stack-blocking frame prevents the bags from tipping over during material pick-up from the upper conveyor line.

[0007] Furthermore, a rack is fixedly connected to the upper conveyor line, and a gear is rotatably connected to the lower conveyor line. The gear meshes with the rack, and a first motor for driving the gear to rotate is fixedly connected to the telescopic line bracket.

[0008] With the rack and pinion mechanism in place, when the first motor outputs power, it drives the upper conveyor line backward to the material bag position and inserts it into the lower end of the uppermost material bag. The first motor drives the gear to stop via a chain, which in turn drives the rack and upper conveyor line to move.

[0009] Furthermore, the upper conveyor line has a drive roller and a driven roller, and a conveyor belt is sleeved between the drive roller and the driven roller. A second motor is fixedly connected to the mounting frame. The second motor is used to drive the drive roller, the feeder, and the pressure roller to rotate. The feeder and the pressure roller rotate in opposite directions.

[0010] With the second motor and pressure roller, when the feeder lifts the bag and places it on the upper conveyor line, the upper conveyor line, the feeder and the lower side of the bag come into contact. Pressure is applied to the bag by the pressure roller, which rotates at the same time to prevent the bag from slipping.

[0011] Furthermore, the stand assembly includes a stand frame, a left slide rail, a right slide rail, and a connecting bridge. The left and right slide rails extend vertically and are respectively located on the left and right sides of the stand frame. The bag tray seat slides between the left and right slide rails.

[0012] The left and right slide rails allow the bag tray to slide up and down on the upright assembly along the left and right slide rails.

[0013] Furthermore, the bag tray seat includes a tray seat, an adjusting seat, a baffle, and guide wheels. The baffle is disposed on both sides of the tray seat, and the guide wheels are rotatably disposed on the baffle. The guide wheels are used to be embedded in the left slide rail and the right slide rail for rolling. A third motor for driving the bag tray seat to rise or fall is fixedly disposed on the upright assembly.

[0014] The guide wheels and the third motor are used to prevent the bags from rolling over. The guide wheels are embedded in the left and right slides and roll. The third motor drives the sprocket and chain to lift the bag tray to the predetermined height.

[0015] Furthermore, two opposing adjustment seats are slidably connected to the pallet seat to clamp and limit the material bag pallet.

[0016] The two adjustable sliding seats allow for the fixing of material bag trays of different sizes.

[0017] Furthermore, the stacking support frame includes an electric cylinder, a stacking plate, a stacking support base, and an adjustable telescopic base; the adjustable telescopic base is set on the stacking support base and is used to install the stacking support base on the upright assembly; the stacking plate is rotatably set on the stacking support base; the two ends of the electric cylinder are respectively hinged to the stacking plate and the stacking support base and are used to drive the stacking plate to rotate; wherein, the adjustable telescopic base is used to adjust the distance between the stacking support plate and the upright assembly.

[0018] By adjusting the electric cylinder, the stacking baffle, and the telescopic seat, the distance between the stacking baffle and the upright assembly is adjusted, thereby blocking bags of different sizes. The electric cylinder causes the stacking baffle to flip, thus fixing the pallet filled with bags onto the pallet seat. This ensures that the pallet placed on the pallet seat does not wobble during material handling and is accurately positioned.

[0019] Furthermore, a power distribution box is installed on the base, and a circuit module is installed inside the power distribution box. The circuit module is electrically connected to the first motor, the second motor, the third motor, and the electric cylinder.

[0020] The base is mainly welded from channel steel, providing an installation location for the upright assembly, the motor that drives the lifting of the material bag pallet seat, and the power distribution box.

[0021] The beneficial effects of this application are as follows:

[0022] 1. The bag tray seat is set up so that the bag can be transported to the telescopic conveyor line by lifting and lowering the bag tray seat. The bag is then unstacked in sequence by the telescopic conveyor line. The upper and lower conveyor lines are set up so that the bag on the tray is placed on the upper conveyor line by the back and forth movement of the upper conveyor line. Then the bag is driven forward by the upper conveyor line to unstack.

[0023] 2. Through the bag blocking mechanism and the material picker, when the upper conveyor line moves backward, the material picker lifts the uppermost bag onto the upper conveyor line, thus preventing the upper conveyor line from being unable to insert between the bags and causing damage to the bags.

[0024] 3. The spring enables the bag-blocking mechanism to apply pressure to the bag, making the bag stick tightly to the upper conveyor line and preventing the bag from slipping on the upper conveyor line;

[0025] 4. By setting up a barrier frame, the barrier frame blocks the material bag when picking up materials on the upper conveyor line, preventing the material bag from tipping over. Attached Figure Description

[0040] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Reference Figure 1-5 A smart depalletizer for material bags includes: a stand assembly 1, a base 3, a material bag pallet seat 2, a telescopic conveyor line 5, a pallet blocking frame 6, a bag blocking mechanism, and a material picker 505. The stand assembly 1 is fixed to the base 3, and the base 3 has feet at its four corners that are fixed to the ground. The stand assembly 1 includes: a stand frame 11, a left slide rail 12, a right slide rail 14, and a connecting bridge 13. The left slide rail 12 and the right slide rail 14 are respectively located on the left and right sides of the stand frame 11. The stand frame 11 is vertically fixed to the base 3, and the left slide rail 12 and the right slide rail 14 extend vertically. The connecting bridge 13 is located at the upper end of the stand frame 11.

[0042] The bag tray base 2 slides vertically behind the upright assembly 1 to hold the bag tray 8. The bag tray base 2 includes: a tray base 21, an adjusting base 22, baffles 23, and guide wheels 24. The baffles 23 are fixedly mounted on both sides of the tray base 21, and the guide wheels 24 are positioned on the baffles 23. Two vertically distributed guide wheels 24 rotate on each of the two baffles 23, and the pulleys on the left and right baffles 23 respectively engage with the left slide rail 12 and the right slide rail 14 to roll. This prevents the bag 7 from rolling over. Two adjusting bases 22 are arranged opposite each other and slide on the tray base 21.

[0043] In one embodiment, the tray base 21 is provided with multiple limiting holes, and the adjusting seat 22 is limited by the bolts cooperating with the limiting holes.

[0044] In one embodiment, the left slide rail 12 and the right slide rail 14 of the upright assembly 1 are made of forklift-specific C-shaped steel, which has better mechanical properties than ordinary channel steel. The left slide rail 12 and the right slide rail 14 have channels for the guide wheels 24 to roll, so as to realize the function of raising or lowering the bag pallet seat 2.

[0045] The stacking support frame 6 includes an electric cylinder 61, a stacking plate 62, a stacking support base 63, and an adjustable telescopic base 64. The stacking support frame 6 is installed on the upper side of the material bag tray base 2 and is used to limit the material bag 7. The adjustable telescopic base 64 is slidably installed on the stacking support base 63.

[0046] In one embodiment, the adjustable telescopic seat 64 is provided with holes, which can be fixed to the retaining seat 63 and the upright assembly 1 by bolts.

[0047] The stacking plate 62 is rotatably mounted on the stacking base 63. The two ends of the electric cylinder 61 are respectively hinged to the stacking base 63 and the stacking plate 62. The stacking plate 62 is rotated by the extension and retraction of the piston end of the electric cylinder 61.

[0048] The telescopic conveyor line 5 includes a telescopic support 506, an upper conveyor line 509, and a lower conveyor line 502 (the upper and lower conveyor lines 509 and 502 are similar to the structure of a belt conveyor). The telescopic support 506 is fixed to the support assembly 1, and the lower conveyor line 502 is fixed to the telescopic support 506. The upper conveyor line 509 is positioned above the lower conveyor line 502 and slides on the telescopic support 506. A pulley 511 is rotatably mounted on the upper conveyor line 509, and the pulley 511 rolls on the telescopic support 506. This allows the upper conveyor line 509 to slide and extend towards the rear of the support assembly 1 for telescopic extension. A gear 503 is rotatably connected to the lower conveyor line 502, and a rack 501 is fixedly connected to the upper conveyor line 509. The gear 503 meshes with the rack 501. A first motor 515 is fixedly connected to the lower conveyor line 502, and the power output end of the first motor 515 is connected to the gear 503 via a chain drive.

[0049] The upper conveyor line 509 includes: a drive roller 504, a driven roller 512, and a conveyor belt 510. The conveyor belt 510 is mounted on the drive roller 504 and the driven roller 512, and the rotation of the drive roller 504 and the driven roller 512 drives the conveyor belt 510 to move. The feeder 505 is rotatably mounted on the upper conveyor line 509.

[0050] In one embodiment, the feeder 505 has a shaft and three circumferentially distributed plates arranged on the shaft. The rotation of the shaft of the feeder 505 causes the three plates to flip continuously, thereby lifting the bag 7 onto the conveyor belt 510.

[0051] The bag-blocking mechanism includes: a mounting frame 513, a deflecting frame 514, a spring 507, and a pressure roller 508. The mounting frame 513 is fixed to the upper conveyor line 509. The deflecting frame 514 is rotatably mounted on the mounting frame 513 and can deflect around its axis of rotation. The pressure roller 508 is rotatably mounted on the deflecting frame 514, and the spring 507 is fixedly connected at both ends to the deflecting frame 514 and the mounting frame 513. When the bag 7 moves between the pressure roller 508 and the conveyor belt 510, the pressure roller 508 applies pressure to the bag 7 under the action of the spring 507 to prevent the bag 7 from slipping. A second motor 516 is fixedly connected to the mounting frame 513. The power output of the second motor 516 transmits power to the drive roller 504, the feeder 505, and the pressure roller 508 through a chain, sprocket, and gear 503. The feeder 505 is driven in the same direction as the drive roller 504, while the pressure roller 508 is driven in the opposite direction.

[0052] A third motor 517 is fixedly connected to the upright assembly 1. The power output end of the third motor 517 pulls the material bag tray seat 2 up and down through a sprocket and a chain.

[0053] In one embodiment, optical sensors and image processing systems are installed at the positions of the left slide rail 12 and the right slide rail 14, as well as on the baffle 23, to provide real-time feedback on the material bag 7 being picked up from the pallet seat 21 as the pallet seat 2 slides up and down, and to detect the speed and distance of the pallet seat 21. Optical sensors and image processing systems are also arranged on the upper conveyor line 509 and the lower conveyor line 502 to detect the forward or backward speed and distance of the upper conveyor line 509. The optical sensors and image processing systems are prior art and will not be described again.

[0054] A power distribution box 4 is fixedly connected to the base 3. A circuit module is installed inside the power distribution box 4. The optical sensor and image processing system are electrically connected to the circuit module. The circuit module is electrically connected to the first motor 515, the second motor 516, the third motor 517, and the electric cylinder 61.

[0055] Working process or usage method:

[0056] 1. Place the bag tray 8 on the bag tray seat 2 and secure it using the two adjusting seats 22. Start the third motor 517 to drive the bag tray seat 2 upward, positioning the uppermost bag 7 on the upper conveyor line. Start the first motor 515 and the second motor 516 to extend the upper conveyor line 509 backward, while the pick-up device 505 and pressure roller 508 rotate. The pick-up device 505 lifts the bag 7 onto the upper conveyor line 509, while the pressure roller 508 prevents the bag 7 from slipping. When the bag 7 is on the conveyor belt 510, the drive roller 504 rotates, moving the bag 7 forward, and then transporting it to the front of the stand assembly 1 for unstacking via the lower conveyor line 502.

[0057] 2. By starting the first motor 515 and outputting power in the reverse direction, the upper conveyor line 509 returns to its initial position. Then, the third motor 517 outputs power, causing the bag tray seat 2 to rise, and the uppermost bag 7 remains at the position of the upper conveyor line 509, continuing the destacking process. Repeat the above operation.
