Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo transfer technology, and more specifically, it relates to a cargo loading and palletizing device. Background Technology
[0002] Palletizing equipment is a type of transport equipment that can move bundled goods over short distances, reducing the labor intensity of workers, saving manpower, and improving efficiency. It is frequently used in warehouses, factories, and other places where goods need to be transferred.
[0003] Common palletizing devices typically consist of a robotic arm driven by a controller and a gripper for grasping goods. The gripping mechanism is usually mounted at the bottom of the drive structure, clamping the goods vertically downwards. However, in practice, this is limited by the device's height. When dealing with taller goods, the height exceeds the gripper's height, forcing the gripper to only contact the upper half of the goods, making stable clamping difficult. Furthermore, the gripping mechanism usually uses gripping structures on both sides to apply inward pressure and clamp the goods. Since there is no support structure below the goods, the clamping force is not too strong to avoid damage from excessive pressure, relying solely on friction on both sides to lift the goods. This can lead to goods slipping during handling, affecting transport. Additionally, common gripping mechanisms rely on rotating gripping structures on both sides, with limited opening range. This means the gripping mechanism can only handle goods of a certain width, lacking adaptability and unusable with excessively wide goods. Utility Model Content

[0030] Please see Figure 1-5 A palletizing device for loading goods includes a palletizing arm 1, a control frame 2 at the output end of the palletizing arm 1, a clamping plate 3 at the side end of the control frame 2, an adjustment groove 4 at the upper end of the clamping plate 3, an extension plate 5 slidably connected in the adjustment groove 4, a positioning groove 6 at the side end of the extension plate 5, a positioning hole 7 on the clamping plate 3, a positioning bolt 8 in the positioning hole 7, and the positioning bolt 8 cooperating with the positioning hole 7 and the positioning groove 6.
[0031] The control frame 2 is slidably connected to a support plate 9, and a control motor 10 is provided on the control frame 2. The output end of the control motor 10 is provided with a drive screw 11, and a mating block 12 is provided on the support plate 9. The mating block 12 is mated with the drive screw 11.
[0032] In this embodiment, the palletizing arm 1 provides support and drives the control frame 2 to move between the goods and the stack. The control frame 2, along with the clamping plate 3, cooperates with the goods to be grasped, allowing the clamping plate 3 to hold the goods. The cooperation between the clamping plate 3 and the control frame 2 ensures that the upper end of the clamping plate 3 is unobstructed. The extension plate 5 is adjusted according to the goods to be transported, allowing it to slide out along the adjustment groove 4 and cooperate with the clamping plate 3 to form a suitable height. The positioning bolt 8 passes through the positioning hole 7 and the positioning groove 6 to keep the extension plate 5 stable, thereby clamping the goods and accommodating the handling of taller goods.
[0033] More specifically, when clamping and handling goods, the control motor 10 is activated, which drives the drive screw 11 to rotate. The drive screw 11 engages with the mating block 12 to provide power, causing the mating block 12 to move with the support plate 9. The support plate 9 slides out of the control frame 2 and extends to the lower end of the goods to support them and prevent them from falling.
[0034] Please see Figure 1 and Figure 3 As an implementation method for width adaptation: a clamping motor 13 is provided on the side of the control frame 2, and a clamping screw 14 is provided inside the control frame 2. The clamping motor 13 cooperates with the clamping screw 14. Two sets of clamping plates 3 are provided, both of which are slidably cooperated with the control frame 2 and cooperate with the clamping screw 14.
[0035] Specifically, the clamping motor 13 is used to control the rotation of the clamping screw 14. The screw 14 is then engaged with the clamping plate 3 by the threads at both ends, which drives the clamping plate 3 to move inward, thereby providing a wider adjustable space to accommodate stacks of goods of different lengths.
[0036] Please see Figure 2 As a further embodiment of the clamping plate: a limiting plate 15 is provided on the side end of the clamping plate 3.
[0037] Specifically, the limiting plate 15 provides a limiting structure to hold the side of the goods in place and prevent the goods from tilting outwards during handling.
[0038] Please see Figures 1-3 As a further implementation of the limiting plate: the inner side of the limiting plate 15 is provided with a sliding post 16, the clamping plate 3 is provided with a sliding groove 17, and the clamping plate 3 is provided with a control screw 18, which cooperates with the sliding post 16.
[0039] Specifically, by operating the control screw 18, the control screw 18 cooperates with the sliding column 16 to provide power to control the movement of the sliding column 16, so that the sliding column 16 moves with the limit plate 15 and adjusts the position of the limit plate 15.
[0040] Please see Figure 3 As a further embodiment of the control frame: the control frame 2 is provided with a limiting ring 19, and the support plate 9 is slidably engaged with the limiting ring 19.
[0041] Specifically, the support plate 9 is restricted by the limiting ring 19, which allows it to slide along the limiting ring 19 to ensure the stability of the extension.
[0042] Please see Figure 3 and Figure 5 As a further embodiment of the support plate: the front end of the support plate 9 is provided with a bevel plug 20.
[0043] Specifically, when the support plate 9 extends, it contacts the cargo through the angled plug 20, and its inclined surface cooperates with the bottom of the cargo to insert the support plate 9 into the lower end of the cargo.
[0044] Please see Figure 4 As a further embodiment of the adjustment groove: the adjustment groove 4 is provided with a support spring 21, which cooperates with the extension plate 5.
[0045] Specifically, the support spring 21 provides thrust, making it easier to raise the extension plate 5 when adjusting it.
[0046] Please see Figure 3 As a further embodiment of the clamping plate: the clamping plate 3 is provided with a first buffer pad 22 on the inner side, and the extension plate 5 is provided with a second buffer pad 23 on the inner side.
[0047] Specifically, when clamping and securing the goods, the first buffer pad 22 and the second buffer pad 23 come into contact with the goods to provide protection and prevent the goods from being damaged by compression.
[0048] In summary, during the use or operation of the overall equipment:
[0049] When using the equipment, connect it to an external power source. The palletizing arm 1 provides support and moves the control frame 2, allowing it to move between the goods and the stacked goods. Adjust the extension plate 5 according to the required goods, allowing it to slide out along the adjustment groove 4. The support spring 21 provides thrust, facilitating the upward movement of the extension plate 5 and ensuring it engages with the clamping plate 3 at a suitable height. The positioning bolt 8 passes through the positioning hole 7 and positioning groove 6, stabilizing the extension plate 5 and clamping the goods. This allows for the handling of taller goods. Operating the control screw 18 engages with the sliding column 16, providing power to move the sliding column 16, which in turn moves the limiting plate 15, adjusting its position.
[0050] When clamping and handling goods, the clamping motor 13 controls the rotation of the clamping screw 14. The threads at both ends of the clamping screw 14 engage with the clamping plate 3, driving the clamping plate 3 to move inward. This causes the clamping plate 3 and the extension plate 5 to engage, clamping and fixing the goods. The first buffer pad 22 and the second buffer pad 23 contact the goods, providing protection and preventing damage from compression. The limiting plate 15 provides a restraining structure, pressing against the side of the goods to prevent them from tilting outward during handling. The control motor 10 then operates, causing the drive screw 11 to rotate, which in turn engages with the mating block. The 12-cooperation mechanism provides power, causing the cooperating block 12 to move along with the support plate 9, allowing the support plate 9 to slide out of the control frame 2. The support plate 9 is then restricted by the limiting ring 19, ensuring stable extension. When the support plate 9 extends, it contacts the cargo via the inclined plug 20, and its inclined surface engages with the bottom of the cargo, allowing the support plate 9 to insert into the lower end of the cargo, supporting it and preventing it from falling. The control frame 2, along with the clamping plate 3, engages with the cargo to be gripped, clamping the cargo. The engagement of the clamping plate 3 with the control frame 2 ensures that the upper end of the clamping plate 3 is unobstructed, thus allowing the cargo to be transported.
