Description
Technical Field

[0002] Traditional stacker technology is mainly used in warehouses with regular shapes, and the design usually relies on fixed tracks or guide rail systems to achieve the stacking and retrieval of goods. However, this design has some obvious disadvantages, especially when dealing with warehouses with irregular layouts, the flexibility of the stacker is particularly insufficient. Traditional stackers usually require a relatively spacious space for the stacking and retrieval of goods. In the case of limited space or irregular shelf layout, existing equipment often cannot meet the actual needs.
[0003] Traditional stackers have poor flexibility when turning, especially when small-radius turns are required, and often fail to perform efficiently. Traditional designs usually rely on a large turning radius to ensure the smooth operation of the equipment, which severely limits the application of the equipment in limited spaces. Especially when stackers need to operate in complex environments, such as when shelves are irregularly configured or warehouses are designed as non-square structures, traditional stackers cannot meet the needs of efficient and high-precision turning and U-turns. At this time, the turning angle of the stacker is non-vertical, and the adjustment of these turning angles is often limited by the structure and design of the equipment itself, resulting in insufficient flexibility in operation during the turning process, making it impossible to achieve a turn.

The support plate insert 135 contacts and cooperates with the rotating base ring 128, and rotates synchronously with the rotating base ring 128 through the lifting guide rods 129.

The electromagnets 123 cooperate with the magnetic limiting disk brackets 124 to adjust the squeezing force between the limiting disk 125 and the friction brake disk 126 .
[0028] The working principle of a universal shuttle stacker disclosed in the present invention is as follows: if the height of the factory building is very high, two moving components are required, wherein the top moving component contacts the ceiling, and the corresponding movable chassis plate 101 is magnetically attracted to the ceiling, and the expansion component provided at the same time can provide support for the top moving component, that is, the contact pressure with the ceiling, and the bottom moving component directly contacts the ground. And the two moving components are synchronously driven. The device is used for irregular warehouses. At present, the warehouses traditionally using stackers are all arranged in a square shape, so that the traditional stacker can take and place goods at the corresponding position, but this requires the overall structure of the factory building to be rebuilt, that is, the factory building must be built according to the stacking situation of the goods, which also leads to the application scenarios of the existing stacker being limited, and it cannot be used in the case of irregular cargo racks, such as non-square shapes, which will cause the turning angle of the stacker to be non-vertical (this is a four-way stacker that is less used at present), and the stacker of the prior art will not be able to be used at this time.
[0029] The device can control the overall turning and U-turn through four independently controlled driving wheel-side motors 104, and can also realize small-radius U-turns and turning. Specifically, by controlling the auxiliary turning electric cylinder 102 on the turning side, the telescopic rod of the auxiliary turning electric cylinder 102 is extended to lift the two wheel groups 103 on the corresponding side off the ground or ceiling (two moving components, if one moving component does not involve the ceiling), and at this time, the two wheel groups 103 on the side in contact with the ground rotate, which will drive the entire device to rotate around the point where the telescopic rod of the auxiliary turning electric cylinder 102 contacts the ground, thereby realizing a small-radius turn. During this process, the movable chassis plate 101 will tilt, so that the movable chassis plate 101 and the supporting base plate 107 (horizontal plane) are no longer parallel. At this time, the supporting base plate 107 and the sliding top rod 105 will slide relative to each other, causing the corresponding top rod support spring 106 to deform (at the same time, the contact position between the sliding top rod 105 and the movable chassis plate 101 will also slide relative to each other). The purpose of setting the limiting plate 109, the movable through hole 110 and the lower pull rod 111 is to limit the relative position between the supporting base plate 107 and the movable chassis plate 101, and prevent the relative position of the two from shifting significantly. The purpose of the lower pull rod 111 and the limiting plate 109 is to press the supporting base plate 107 toward the movable chassis plate 101, so that the top rod support spring 106 is in a compressed state, and the elastic connection state between the supporting base plate 107 and the movable chassis plate 101 is always guaranteed. That is to prevent the tilt of the movable chassis plate 101 from affecting the supporting base plate 107.
[0030] If two sets of guide rails 114 are used, the rotating ring frame support plate 138 needs to be installed on the upper set of guide rails 114. Conversely, if one set of guide rails 114 is used, it can only be installed on the corresponding guide rails 114. The pallet plug plate 135 lifts the goods. According to the height of the goods on the shelf, when the height is low, the pulling motor 132 is started, and the output shaft of the pulling motor 132 drives the pulling wire shaft 133 to rotate. The pulling wire shaft 133 winds up the pulling rope 134, and then pulls the pallet plug plate 135 to lift the guide rod 1 29 and the extended disassembly guide rod 136 slide on the pallet plug plate 135, thereby driving the pallet plug plate 135 to move upward, and at the same time controlling the rotation control motor 139, the output shaft of the rotation control motor 139 will drive the rotating brake gear 127 to rotate, the rotating brake gear 127 drives the rotating base ring 128 to rotate, and the rotating base ring 128 drives the lifting guide rod 129, the extended disassembly guide rod 136 and the rotating ring frame 137 to rotate, so that the goods on the pallet plug plate 135 rotate with it, and at this time, the goods can be taken and placed on the shelves at different angles. When the position of the goods on the shelf is higher, the pulling motor 132 and the extended lifting motor 115 are started at the same time, wherein the starting of the pulling motor 132 is the same as the working principle mentioned above, and the output shaft of the extended lifting motor 115 will drive the extended lifting screw 116 to rotate, and the rotation of the extended lifting screw 116 will drive the lifting platform 113 to move on a set of guide rods 114 at the bottom, thereby causing the initial height of the pallet plug plate 135 to increase, and then cooperate with the relative displacement of the pallet plug plate 135 and the lifting guide rod 129, thereby extending the vertical movement range of the pallet plug plate 135.
[0031] In order to ensure the transmission speed between the extended lifting screw 116 and the lifting platform 113, the extended lifting screw 116 uses a larger pitch, which also causes the weight on the lifting platform 113 to be applied to the extended lifting screw 116, thereby easily causing the extended lifting screw 116 to passively rotate (when the extended lifting motor 115 stops working). Therefore, a friction brake disc 126 is provided at the top of the extended lifting screw 116 to limit the rotation of the friction brake disc 126 to limit the rotation of the extended lifting screw 116. Specifically, in the default state, the limiting disc 126 5 will be in close contact with the friction brake disc 126 under the elastic force of the four auxiliary downward compression springs 121, so that the friction force between the limiting disc 125 and the friction brake disc 126 reaches the maximum value, making the friction brake disc 126 unable to rotate. When the electromagnet 123 is started, the electromagnet 123 will attract the magnetic limiting disc bracket 124, and the magnetic limiting disc bracket 124 will drive the limiting disc 125 to compress the auxiliary downward compression springs 121, so that the friction brake disc 126 and the limiting disc 125 are separated. At this time, the extension lifting motor 115 can be controlled to drive the extension lifting screw 116 to rotate.
