Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a silo, in particular to a palletizing silo. Background Art

[0002] During the machining process, in order to improve machining efficiency, the workpieces before and after machining are stacked and placed. In the past, the stacking racks used for stacking were single-layer structures, and the number of workpieces that could be placed was limited.

[0003] In response to the above problems, people have designed various stacking silos, and some have even applied for patents. For example, Chinese patent literature discloses a drawer-type storage silo [application number: 202221033869.2; authorization announcement number: CN218619028U], which includes a frame, a silo protection cover, and an operation button. The frame is a square structure welded from square steel. The silo protection cover is arranged on the front and rear sides of the frame. The operation button is arranged on the left or right side of the silo protection cover. The mobile pallet is fixedly arranged at the upper position of the mobile push-pull device. The mobile pallet is used to place workpieces. The dynamic push-pull device is opened and closed by an operating button and is used to push the mobile tray to the right. The mobile tray is divided into mobile tray one, mobile tray two, mobile tray three and mobile tray four. The mobile push-pull device is divided into mobile push-pull device one, mobile push-pull device two, mobile push-pull device three and mobile push-pull device four. Mobile push-pull device one is symmetrically fixed at the front and rear sides of the upper part of the frame. Mobile push-pull devices two, three and four are symmetrically arranged at the lower position of mobile push-pull device one in turn. Mobile trays one, two, three and four are fixed at the upper positions of mobile push-pull devices one, two, three and four respectively.

[0004] The above-mentioned drawer-type storage silo can increase the storage capacity of workpieces and can cooperate with robots to realize the stacking and automatic grasping of workpieces. However, the mobile push-pull devices one, two, three and four need to move back and forth, so sufficient displacement space must be guaranteed, which makes the silo large and inconvenient for installation and layout. Moreover, each layer needs to be equipped with a corresponding mobile pallet to place the workpieces. In addition, there needs to be sufficient spacing between each mobile pallet to place the workpieces and set up the mobile push-pull devices. The workpieces cannot be stacked and placed, and the number of stacked workpieces is still not ideal, affecting work efficiency. Summary of the Invention

[0005] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and to provide a stacking silo with a compact structure, which can increase the number of stacked workpieces and improve work efficiency.

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example 1

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the stacking silo includes a bottom plate 1, above which is provided a top plate 2 for supporting workpieces, the top surface of the bottom plate 1 is connected to a plurality of material placing members 3 which pass through the top plate 2 and for stacking the workpieces, and the bottom plate 1 is also provided with a lifting structure for driving the top plate 2 to rise and fall.

[0025] The material placement element 3 in this stacking silo acts as a limiter and guide. Before use, the workpiece first placed at the corresponding material placement element 3 moves down along the material placement element 3 and is supported by the top. The workpieces subsequently placed are stacked in sequence, forming multiple groups of multi-layered workpieces, so that a large number of workpieces can be stacked. During use, the lifting structure drives the top plate 2 upward to lift the workpiece on the top layer so that the workpiece on the top layer is exposed to the material placement element 3. The lifting structure stops working, and the robot grasps the workpiece on the top layer for processing (in actual manufacturing, the robot can grasp the workpiece on the top layer in sequence, or the robot can grasp multiple workpieces on the top layer in a set area in sequence, or the robot can grasp all workpieces on the top layer at once). After all the workpieces on the top layer are processed, the lifting structure works again to lift the top plate 2 again, again making the top workpiece exposed to the material placement element 3 for processing. This cycle repeats until all workpieces are processed. After that, the lifting structure lowers the top plate 2 to reset. The stacking silo has a compact structure, allowing workpieces to be stacked, resulting in a large number of workpieces being stacked and high work efficiency.

[0026] In this embodiment, the lifting structure includes a support plate 4 positioned below a base plate 1. Several screw rods 5 are inserted into the support plate 4 and extend vertically through the base plate 1 and the top plate 2. A threaded sleeve 6 is fixedly connected to the top plate 2, into which each screw rod 5 is threadedly connected. A motor 7 is fixedly connected to the support plate 4. The output shaft of the motor 7 is fixedly connected to a driving gear 8. Each screw rod 5 is fixedly connected to a driven gear 9. The driving gear 8 is connected to each driven gear 9 via a transmission belt 10. The motor 7 drives the driving gear 8 to rotate, and the transmission belt 10 causes the driven gears 9 to rotate synchronously. Each driven gear 9 rotates each screw rod 5, causing the threaded sleeve 6 to rise and fall synchronously along the screw rod 5, thereby achieving the lifting and lowering of the top plate 2. In this embodiment, the support plate 4 is embedded with bearings for the screw rods 5, and the base plate 1 is embedded with bearings for the screw rods 5. The driving gear 8, each driven gear 9, and the transmission belt 10 are all located between the base plate 1 and the support plate 4. This results in a compact structure, and the transmission belt 10 is less susceptible to damage, resulting in a long service life.

[0027] The top of each screw rod 5 is inserted into the frame-shaped positioning frame 11, which makes the structure stable, the screw rod 5 drives smoothly, and the workpiece moves steadily.

[0028] A second screw sleeve 16 is fixedly connected to the bottom of the support plate 4. The support plate 4 is positioned on two parallel guide rails 18 via a slider 17. A mounting plate 19 is fixedly connected between the two guide rails 18. A transmission motor 20 is fixedly connected to the mounting plate 19. The output shaft of the transmission motor 20 is fixedly connected to a second screw rod 21 threadedly connected to the second screw sleeve 16. The transmission motor 20 drives the support plate 4 to move along the guide rails 18 via the second screw rod 21, thereby driving the bottom plate 1, the top plate 2, and the various workpieces to move, facilitating the robot's adjustment and alignment, and facilitating manual material discharge.

[0029] Two cross beams 22 are fixedly connected to the bottom between the two guide rails 18, and rollers 23 are provided at the bottom of both ends of the two cross beams 22, which makes it easy to carry the stacking silo and easy to operate.

[0030] The material holding member 3 is in the shape of a hollow tube. Its side has a connecting groove 31 extending axially and connected to its inner cavity. The bottom of the material holding member 3 is screwed to the base plate 1. Of course, in actual manufacturing, the material holding member 3 can be in the shape of a straight rod, and the bottom of the material holding member 3 is screwed to the base plate 1.

[0031] In this embodiment, two top plates 2 are positioned above the bottom plate 1. Eight screw rods 5 are inserted into the support plate 4. Groups of four screw rods 5 extend through the four corners of the bottom plate 1 and corresponding top plate 2. Two motors 7 are fixedly connected to the support plate 4. The motors 7 drive the four screw rods 5 on the corresponding top plates 2 via their respective drive gears 8. One top plate 2 is penetrated by an array of hollow tubular material placement members 3 with connecting slots 31. The other top plate 2 is penetrated by an array of straight rod material placement members 3. Here, three material placement members 3 form a circle to accommodate block-shaped workpieces.

[0032] Through the above arrangement, the stacking silo can be used for loading and unloading of two different workpieces, with high work efficiency. Of course, during actual manufacturing, the material placement member 3 can be set according to the shape of the workpiece to meet the requirements of stacking and placing the workpieces. Example 2

[0033] like Figure 5 and Figure 6As shown, the structure and principle of this embodiment are basically the same as those of embodiment 1. The difference is that the lifting structure in this embodiment includes a support plate 4 located below the bottom plate 1, and a plurality of screw lifts 12 connected in sequence are fixedly connected to the support plate 4. The transmission screw 121 of each screw lift 12 is set through the bottom plate 1, and the top plate 2 is fixedly connected to a transmission screw sleeve 13 threadedly connected to each transmission screw 121. A gear box 15 driven by a drive motor 14 is fixedly connected to the support plate 4, and the output shaft of the gear box 15 is connected to the input shaft of the adjacent screw lift 12. The drive motor 14 drives the gear box 15 to work, and the output shaft of the gear box 15 drives the input shaft of the adjacent screw lift 12 to rotate. Because the screw lifts 12 are connected in series, the transmission screw 121 of each screw lift 12 rotates synchronously, so that the transmission screw sleeve 13 drives the top plate 2 to rise and fall.

[0034] In this embodiment, the stacking silo has two groups of four screw lifts 12 connected in sequence, the number of the bottom plate 1 and the top plate 2 are two, the material placing parts 3 are straight rod-shaped, and each material placing part 3 is in two arrays and connected to the corresponding bottom plate 1. The transmission screw 121 of each group of screw lifts 12 passes through the corresponding bottom plate 1, and the top of each transmission screw 121 is passed through the frame-shaped positioning frame 11. This makes the structure stable, the transmission screw 121 transmits smoothly, and the workpiece displacement is stable.
