Technical Field

[0001] The utility model relates to the technical field of palletizing and conveying, in particular to a material handling device with an automatic identification function for a five-axis palletizer. Background Art

[0002] With the development of technology, it has become a trend to replace traditional manual labor with automatic or semi-automatic machinery. For example, in palletizing devices, most traditional technologies require manual cooperation to stack items. Later, mechanization began to take place. For example, a lifting device is used in conjunction with a vacuum suction cup mechanism to load and palletize the plates before and after processing. The five-axis palletizer is a palletizer with multi-directional movement, which can facilitate palletizing.

[0003] In order to facilitate the handling of materials, for example, the Chinese utility model patent with the announcement number CN210794519U discloses a new and efficient palletizing device based on an AGV transport vehicle, which relates to the field of automatic palletizing and conveying technology. In order to solve the problem of low working efficiency of the existing palletizing device using pallet warehouses, pallet conveyors and other equipment to achieve palletizing of materials, a palletizing robot is installed above the base, a gripper is installed below one end of the palletizing robot, a material picking platform is installed below the gripper, a material bag is placed above the material picking platform, and several material bags are placed and distributed in sequence. A placement rack is installed in front between the base and the material picking platform, a pallet is placed above the placement rack, a first AGV transport vehicle is placed below the pallet, a second AGV transport vehicle is placed on one side of the first AGV transport vehicle, and a third AGV transport vehicle is placed on the other side of the first AGV transport vehicle.

[0004] However, there are still some problems. Although the pallet is firmly fixed on the AGV transport vehicle by installing a magnetic block and attracting the iron plate, the subsequent disassembly of the pallet is inconvenient due to the presence of a certain magnetic force. Moreover, when the pallet is placed on the AGV transport vehicle, the accuracy of the pallet position cannot be guaranteed and there is a certain deviation. Therefore, a material handling device with automatic identification function for a five-axis palletizer is proposed to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a material handling device with automatic identification function for a five-axis palletizer, which has the advantages of accurate pallet positioning and solves the problem of not being able to ensure the accurate position of the pallet when placing it on an AGV transport vehicle.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a material handling device with automatic identification function for a five-axis palletizer, comprising a transport vehicle body, four buffer springs fixed inside the transport vehicle body, a telescopic rod fixed to the top of the buffer spring and extending through the top of the transport vehicle body, the telescopic rod being fixed to the transport vehicle body, and a placement plate fixed to the top of the four telescopic rods;

[0007] A driving motor is fixed inside the placement plate, and a driving rod rotatably connected to the placement plate is fixed to the output shaft of the driving motor. The outer surface of the driving rod is threadedly connected to two positioning blocks that pass through the top of the placement plate. A sensing component is provided inside the positioning block on the left side, and the sensing component is used to control the shutdown of the driving motor. An identification button that passes through the top of the transport vehicle body is fixed inside the transport vehicle body;

[0008] The sensing assembly includes a push rod, a push block, a sensing button, a connecting plate and a reset spring. The interior of the positioning block on the left is slidably connected to the push rod, the right side of the push rod is fixed to the push block, the interior of the positioning block on the left is fixed to the sensing button that passes through the right side of the left positioning block, the left side of the push rod is fixed to the connecting plate, and the positioning block and the connecting plate on the left are fixed to the reset spring.

[0009] Furthermore, the telescopic rod includes an extension rod fixed to the transport vehicle body, an outer surface of the extension rod is slidably connected to an extension block fixed to the placement plate, and a bottom of the extension block is fixed to a buffer spring.

[0010] Furthermore, sliding blocks are fixed on both the left and right sides of the extension block, and a sliding groove slidably connected to the sliding blocks is provided inside the transport vehicle body.

[0011] Furthermore, a fixed bearing is fixed to the left side wall of the inner cavity of the placement plate, and the interior of the fixed bearing is fixed to the driving rod.

[0012] Furthermore, two sections of threaded strips with opposite threads are fixed on the outer surface of the driving rod, and a threaded hole adapted to the threaded strips is provided inside the positioning block.

[0014] Furthermore, the return spring is a high-strength spring, and a rubber pad is fixed on the top of the cushion block.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] The five-axis palletizer uses a material handling device with an automatic identification function. After placing the pallet on the top of the placement plate, the pallet has a certain weight, so the placement plate moves downward to press the identification button, and then transmits an electrical signal to start the drive motor to drive the drive rod to rotate. After the positioning block positions the pallet, the sensing button inside the sensing component is squeezed, thereby transmitting an electrical signal to turn off the drive motor. The overall structure is simple, and the pallet can be identified and positioned, making the overall structure more practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 2 In this embodiment, a material handling device with automatic identification function for a five-axis palletizer includes a transport vehicle body 1. The transport vehicle body 1 is an AGV transport vehicle equipped with an automatic guidance device such as an electromagnetic or optical device, and can travel along a specified guide path. A pad 10 is fixed on the top of the transport vehicle body 1. The set pad 10 can effectively limit the downward movement range of the placement plate 4. A rubber pad is fixed on the top of the pad 10. Four buffer springs 2 are fixed inside the transport vehicle body 1. The set buffer springs 2 have a certain rigidity, so that the placement plate 4 will not contact the identification button 9 when it is unloaded.

[0023] In addition, a telescopic rod 3 that passes through the top of the transport vehicle body 1 is fixed to the top of the buffer spring 2. The telescopic rod 3 includes an extension rod fixed to the transport vehicle body 1. The outer surface of the extension rod is slidably connected to an extension block fixed to the placement plate 4. The bottom of the extension block is fixed to the buffer spring 2. Sliding blocks are fixed on both sides of the extension block. A sliding groove that is slidably connected to the sliding block is provided inside the transport vehicle body 1. The setting of the sliding block and the sliding groove makes the movement of the extension block more stable. The telescopic rod 3 is fixed to the transport vehicle body 1, and a placement plate 4 is fixed to the top of the four telescopic rods 3.

[0024] Furthermore, a driving motor 5 is fixed inside the placement plate 4, and the output shaft of the driving motor 5 is fixed with a driving rod 6 that is rotatably connected to the placement plate 4. A fixed bearing is fixed to the left side wall of the inner cavity of the placement plate 4, and the interior of the fixed bearing is fixed to the driving rod 6. The set fixed bearing makes the rotation of the driving rod 6 more stable. The outer surface of the driving rod 6 is threadedly connected with two positioning blocks 7 that pass through the top of the placement plate 4. The positioning block 7 passes through the placement plate 4, so that the placement plate 4 limits the rotation of the positioning block 7. The outer surface of the driving rod 6 is fixed with two sections of threaded strips with opposite threads, and the interior of the positioning block 7 is provided with a threaded hole that is compatible with the threaded strip. The interior of the left positioning block 7 is provided with a sensing component 8, and the sensing component 8 is used to control the shutdown of the driving motor 5. The interior of the transport vehicle body 1 is fixed with an identification button 9 that passes through the top of the transport vehicle body 1.

[0025] In general, when the tray is placed on top of the placement plate 4, the tray has a certain weight, so that the placement plate 4 will move downward and contact the identification button 9. The buffer spring 2 provided allows the placement plate 4 to have space to move downward while buffering the vibration to a certain extent, making the overall structure more practical.

[0026] See also Figure 3 The sensing assembly 8 in this embodiment includes a push rod 801, a push block 802, a sensing button 803, a connecting plate 804 and a return spring 805. The interior of the left positioning block 7 is slidably connected to the push rod 801, and the right side of the push rod 801 is fixed to the push block 802. The return spring 805 is a high-strength spring, which makes it difficult for the return spring 805 to deform. A sponge pad is fixed to the right side of the push block 802. The interior of the left positioning block 7 is fixed to the sensing button 803 that passes through the right side of the left positioning block 7. When the sensing button 803 is pressed, the internal circuit is connected. The left side of the push rod 801 is fixed to the connecting plate 804, and the left positioning block 7 and the connecting plate 804 are fixed with the return spring 805.

[0027] In general, when the two positioning blocks 7 position the tray, the push block 802 presses the sensing button 803 , thereby transmitting an electrical signal to turn off the drive motor 5 .

[0028] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0029] The working principle of the above embodiment is:

[0030] After the tray is placed on the top of the placement plate 4, the tray has a certain gravity, so that the placement plate 4 pushes the telescopic rod 3 to move downward to squeeze the buffer spring 2, and the placement plate 4 will contact the identification button 9, so that the current inside the identification button 9 is connected, and the electrical signal is transmitted to start the drive motor 5. The rotation of the drive motor 5 will cause the drive rod 6 to rotate together, and then the two non-rotatable positioning blocks 7 will move due to the squeezing of the threads, so that the positioning block 7 can push the tray to position. Before the left positioning block 7 contacts the tray, the pushing block 802 will contact the tray first. Because the reset spring 805 has a certain rigidity, it limits the pushing block 802 and the pushing rod 801 And the connecting plate 804 moves to the left, so that the pushing block 802 can push the tray to the right until it contacts the right positioning block 7. At this time, because the right positioning block 7 limits the movement of the tray, when the two positioning blocks 7 move, all the force will be transmitted to the pushing block 802, thereby overcoming the rigidity of the reset spring 805, so that the pushing block 802, the pushing rod 801 and the connecting plate 804 move to the left, and then the pushing block 802 squeezes the sensing button 803, so that the whole recognizes that the positioning of the tray has been completed, and then the drive motor 5 is turned off. The overall structure is simple, and the positioning of the tray can be completed simply and effectively, making the overall more practical.
