Description

Technical Field

[0001] This utility model relates to the field of pallet loading machine technology, and in particular to a dual-station fully automatic pallet loading machine. Background Technology

[0002] In the process of modern industrial automation, dual-station fully automatic pallet loading machines have become key equipment for improving operational efficiency in industries such as logistics warehousing, food processing, and pharmaceutical manufacturing due to their efficient cargo and pallet assembly capabilities. Among them, pallet loading, as the starting point of the pallet loading machine's operation, directly affects the overall working efficiency and stability of the equipment.

[0003] Currently, most dual-station fully automatic pallet loading machines on the market still use a simple stacking method for pallet loading. This method mainly relies on gravity to separate the stacked pallets one by one from top to bottom. However, in practical applications, this method has many drawbacks. On the one hand, pallets are easily deformed due to environmental factors when stored in a stack for a long time, and there is a large friction between the pallets. This makes it easy for the pallets to stick and jam during the separation process. Once such a situation occurs, the pallets cannot be accurately transported to the designated position according to the predetermined rhythm. This will not only lead to a significant reduction in the working efficiency of the pallet loading machine, but may also cause excessive wear of mechanical parts, transmission system jamming and other equipment failures due to jamming, increasing equipment maintenance costs and downtime. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, the pallets are prone to sticking and jamming during the separation process. Once such a situation occurs, the pallets cannot be accurately transported to the designated position according to the predetermined rhythm. This not only leads to a significant reduction in the working efficiency of the pallet loading machine, but may also cause excessive wear of mechanical parts, jamming of the transmission system and other equipment failures due to jamming, increasing the maintenance cost and downtime of the equipment. Therefore, a dual-station fully automatic pallet loading machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-station fully automatic pallet loading machine includes a frame on which two parallel transport units are arranged. A robotic arm is mounted on the side of the frame, and a pallet stacking rack is mounted on the side of the frame. Partitions are fixed in a linear array on the pallet stacking rack, and a placement shell is fixed on the top of the partitions. A placement slot is opened in the placement shell, and a sliding mechanism is provided on the pallet stacking rack.

[0007] Preferably, the sliding mechanism includes a fixed block fixed to the top of the partition, a fixed rod fixed to the fixed block, a slider sliding on the outer surface of the fixed rod, a placement shell fixed to the side of the slider, and a spring sleeved on the outer surface of the fixed rod, with the two ends of the spring respectively fixedly connected to the fixed block and the slider.

[0008] Preferably, the pallet stacking rack is provided with an ejection mechanism for pushing the placement shell. The ejection mechanism includes a lead screw rotatably connected to the pallet stacking rack via a bearing. A limit rod is also fixed on the pallet stacking rack. A threaded block is threadedly connected to the outer surface of the lead screw. A lifting block slides on the outer surface of the limit rod. A connecting block is fixed between the threaded block and the lifting block. A mounting bracket is fixed at the bottom of the connecting block.

[0009] Preferably, an electric push rod is fixed on the mounting bracket, and a push block is fixed to one end of the extension rod of the electric push rod.

[0010] Preferably, a second motor is mounted on the frame, and the bottom end of the lead screw is fixedly connected to the output shaft end of the second motor.

[0011] Preferably, the transport unit includes a drive roller rotatably connected to a frame, two drive rollers being connected by a transmission belt, and a motor for driving the drive rollers to rotate is mounted on the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Through the setting of partitions and placement shells, the partitions are fixed on the pallet stacking rack in a linear array, providing stable support for the placement shells. The placement slots inside the placement shells can accurately position the pallets, ensuring that the pallets are stable in position during storage. Through the setting of the ejection mechanism, the ejection action of the placement shells can be precisely controlled to achieve orderly pallet loading, avoiding the phenomenon of pallet sticking and jamming in traditional stacking loading, ensuring that the pallets are accurately and stably transported to the designated position, and greatly improving loading efficiency and reliability.

[0014] 2. Through the setting of the sliding mechanism, the fixed block, fixed rod, slider and spring work together. When the placement shell is subjected to force, the slider can slide along the fixed rod, and the spring plays a role in buffering and resetting. This gives the placement shell a certain degree of flexibility on the pallet stacking rack, which can effectively adapt to the impact force generated during pallet placement and handling. In addition, after the ejection mechanism pushes the placement shell out, it can be reset in time to avoid the placement shell affecting the loading operation of other pallets.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Reference Figures 1-6 The dual-station fully automatic pallet loading machine includes a frame 1, on which two parallel transport units are arranged. A robot arm 3 is arranged on the side of the frame 1, and a pallet stacking rack 4 is arranged on the side of the frame 1. Partitions 5 are fixed in a linear array on the pallet stacking rack 4. A placement shell 6 is fixed on the top of the partitions 5. A placement slot 7 is opened in the placement shell 6. A sliding mechanism is provided on the pallet stacking rack 4.

[0025] Furthermore, the sliding mechanism includes a fixed block 81 fixed to the top of the partition 5, a fixed rod 82 fixed on the fixed block 81, a slider 83 sliding on the outer surface of the fixed rod 82, a housing 6 fixed to the side of the slider 83, and a spring 84 sleeved on the outer surface of the fixed rod 82, with the two ends of the spring 84 fixedly connected to the fixed block 81 and the slider 83 respectively.

[0026] Furthermore, the pallet stacking rack 4 is provided with an ejection mechanism for pushing the placement shell 6. The ejection mechanism includes a lead screw 92 rotatably connected to the pallet stacking rack 4 via a bearing. A limit rod 93 is also fixed on the pallet stacking rack 4. A threaded block 94 is threadedly connected to the outer surface of the lead screw 92. A lifting block 95 slides on the outer surface of the limit rod 93. A connecting block 96 is fixed between the threaded block 94 and the lifting block 95. A mounting bracket 97 is fixed to the bottom of the connecting block 96.

[0027] Furthermore, an electric push rod 98 is fixed on the mounting bracket 97, and a push block 99 is fixed to one end of the extension rod of the electric push rod 98.

[0028] Furthermore, a second motor 91 is mounted on the frame 1, and the bottom end of the lead screw 92 is fixedly connected to the output shaft end of the second motor 91.

[0029] The linear array of fixed partitions 5 on the pallet stacking rack 4 provides stable support for the placement shell 6, preventing the pallet from shifting or tipping over when placed inside. This design allows pallets that are traditionally stacked together to be placed separately. When placing a pallet, the motor 91 on the frame 1 starts, driving the lead screw 92 to rotate on the pallet stacking rack 4. The threaded block 94, which is threaded to the lead screw 92, moves linearly along the lead screw 92 when it rotates. At the same time, the limit rod 93 restricts the movement direction of the lifting block 95, ensuring that it can only slide on the surface of the limit rod 93. The threaded block 94 and the lifting block 95 are connected by the connecting block 96, which drives the mounting frame 97, the electric push rod 98, and the push block 99 to lift as a whole. When the target height is reached, the electric push rod 98 extends, pushing the push block 99 to lift the placement shell 6. The pallet is ejected from the pallet stacking rack 4, and the pallet inside the placement shell 6 is pushed to the designated position. This process can be precisely controlled by a PLC controller. The PLC controller is electrically connected to the electric push rod 98 and the motor 91. When the push block 99 moves, it pushes the placement shell 6 out of the pallet stacking rack 4, making it easier for the robot arm 3 to grip and load the pallet. The placement shell 6 drives the slider 83 fixed on its side to slide on the surface of the fixed rod 82. One end of the spring 84 is connected to the fixed block 81, and the other end is connected to the slider 83. When the slider 83 slides, the spring 84 is compressed or stretched, which plays a role in buffering external forces. After the loading is completed, the spring 84 returns to its initial position by elastic reset, driving the slider 83 and the placement shell 6 back to the initial position, preparing for the next loading and preventing the placement shell 6 from affecting the loading operation of other pallets.

[0030] Based on Example 1, Example 2:

[0031] Reference Figures 1-6 ,

[0032] Furthermore, the transport unit includes a drive roller 21 rotatably connected to the frame 1, and the two drive rollers 21 are connected by a transmission belt 22. A motor 23 for driving the drive rollers 21 to rotate is installed on the frame 1.

[0033] When the placement shell 6 is ejected, the motor 23 on the frame 1 drives the transmission roller 21 to rotate. The transmission belt 22 between the two transmission rollers 21 rotates in a cycle under the drive of the transmission rollers 21. The ejected pallet is picked up by the robot arm 3 and falls onto the transmission belt 22. Under the action of the friction of the transmission belt 22, the pallet is smoothly transported to the upper pallet station. The two transportation units of the dual station work in parallel, and each part works together to realize the fully automatic pallet loading and the assembly of goods with the pallet.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
