Description

Technical Field

[0001] This invention relates to the field of shelving storage devices, and more particularly to a shelving placement device and a three-dimensional storage system. Background Technology

[0002] After the profiles are manufactured, they are stacked on shelves for easy transportation and storage. Each profile model corresponds to one shelf. When the shelves are called up, clamps are used to connect the shelves, and the shelves are moved horizontally by dragging, so that the shelves can be put into or taken out of the warehouse. However, due to the large weight of the shelves and the fact that profiles can be placed on the shelves, the increased dragging force can cause uneven stress on the clamps, which can easily lead to deformation when the shelves are dragged for a long time, thus reducing the service life of the clamps. Summary of the Invention

[0003] The purpose of this invention is to provide a shelf placement device, which controls the snap-fit ​​assembly to raise and lower the snap-fit ​​plate to the upper surface of the snap-fit ​​moving plate when needed, thereby using the snap-fit ​​clamp formed between the snap-fit ​​plates to hold the shelf, and then using the X-axis transfer assembly to drive the shelf to move, so that the shelf can be pushed to be placed on the receiving base frame.

[0043] like Figure 1-5 A shelf placement device includes: a receiving base frame 21, a snap-fit ​​assembly 22, and an X-axis transfer assembly 23;

[0044] The receiving base frame 21 is provided with a transfer channel 210 along its length;

[0045] The snap-fit ​​assembly 22 includes: a snap-fit ​​moving plate 221, a snap-fit ​​plate 222, a snap-fit ​​gear 224, and a snap-fit ​​driver 223;

[0046] The output end of the X-axis transfer assembly 23 is connected to the snap-fit ​​moving plate 221, and is used to drive the snap-fit ​​moving plate 221 to move horizontally on the transfer channel 210. The snap-fit ​​moving plate 221 is provided with a pair of snap-fit ​​guide ports 2211, and the snap-fit ​​plates 222 are respectively installed in the snap-fit ​​guide ports 2211 in a lifting and lowering manner. A snap-fit ​​clamping opening 220 is formed between two adjacent snap-fit ​​plates 222. The snap-fit ​​plate 222 is provided with snap-fit ​​teeth 2221, and the snap-fit ​​gear 224 meshes with the snap-fit ​​teeth 2221. The output end of the snap-fit ​​driver 223 is connected to the snap-fit ​​gear 224, and is used to drive the snap-fit ​​gear 224 to rotate, thereby driving the snap-fit ​​plate 222 to move up and down, so that the snap-fit ​​clamping opening 220 extends or retracts on the upper surface of the snap-fit ​​moving plate 221 to snap the shelf. The X-axis transfer assembly 23 drives the snap-fit ​​moving plate 221 to move, so that the snap-fit ​​clamping opening 220 pushes the shelf horizontally to the receiving base frame 21.

[0047] This solution provides a shelf placement device, which controls the snap-fit ​​assembly 22 to raise and lower the snap-fit ​​plate 222 to the upper surface of the snap-fit ​​moving plate 221 when needed, thereby using the snap-fit ​​clamp 220 formed between the snap-fit ​​plates 222 to clamp the shelf, and then using the X-axis transfer assembly 23 to drive the shelf to move, so that the shelf can be pushed to be placed on the receiving base 21. The snap-fit ​​plate 222 has a long service life and is not easily deformed, which solves the problem of low service life when clamping and pushing large shelves.

[0048] In automated warehouses, shelves are typically stacked. When a shelf needs to be moved out or placed back into the warehouse, the placement device 2 is used to access it. The X-axis transfer assembly 23 drives the locking moving plate 221 to the shelf's position, activating the locking driver 223. The output of the locking driver 223 drives the locking gear 224 to rotate, which in turn causes the locking teeth 2221 of the locking plate 222 to move relative to the locking gear 224. The locking plate 222 moves up and down along the locking guide port 2211, thus engaging the locking clamp 220 with the shelf. The latching position allows the X-axis transfer assembly 23 to be activated. The X-axis transfer assembly 23 drives the latching moving plate 221 to move horizontally, thereby transferring the shelf laterally to the receiving base frame 21. During the transfer, the latching plate 222 will adhere to the inner wall of the latching guide port 2211. When the latching plate 222 pushes the shelf to move, the inner wall of the latching guide port 2211 can provide support for the latching plate 222, thereby preventing the latching plate 222 from deforming and improving the service life of the latching plate 222. This solves the problem of low service life when clamping and pushing large shelves.

[0049] Alternatively, the same snap-fit ​​moving plate 221 may be provided with multiple pairs of snap-fit ​​plates 222 along the conveying direction, so that the upper surface of the snap-fit ​​moving plate 221 is provided with multiple snap-fit ​​clamps 220.

[0050] This solution preferably uses multiple pairs of snap-fit ​​guide ports 2211 on the snap-fit ​​moving plate 221. When multiple pairs of snap-fit ​​guide ports 2211 are equipped with snap-fit ​​plates 222, multiple snap-fit ​​clamping slots 220 can be formed on the snap-fit ​​moving plate 221. The multiple snap-fit ​​clamping slots 220 can correspond to different positions of the snap-fit ​​shelf, so that the snap-fit ​​moving plate 221 can snap-fit ​​at least two snap-fit ​​positions 011 of the shelf 01. When the shelf is snap-fitted and limited at both points along the conveying direction, the shelf can maintain a stable position during the conveying process, and its angle is always in the length direction of the receiving base frame 21. This can prevent the shelf from deviating at an angle during the conveying process and causing it to collide with the warehouse during the storage and retrieval of the automated warehouse.

[0051] Alternatively, the snap-fit ​​assembly 22 may include: a position sensing device 25;

[0052] The snap-fit ​​plate 222 exposes the top plate 2222 on the upper surface of the snap-fit ​​moving plate 221; the upper surface of the top plate 2222 is provided with an identification hole 2223, which is close to the front and rear edges of the top plate 2222 in the horizontal movement direction; the position sensing device 25 is installed in the identification hole 2223; the position sensing device 25 is communicatively connected to the X-axis transfer assembly 23.

[0053] In its initial state, the snap-fit ​​plate 222 is fully retracted into the snap-fit ​​guide opening 2211. At this time, the top plate 2222 of the snap-fit ​​plate 222 can contact the upper surface of the snap-fit ​​moving plate 221. The top plate 2222 is provided with an identification hole 2223, and the identification hole 2223 is located at the front and rear edges of the top plate 2222 in the horizontal movement direction. That is, the snap-fit ​​moving plate 221 drives the snap-fit ​​plate 222 and its top plate 2222 to move horizontally, and the identification hole 2223 is provided near the front and rear edges of the top plate 2222 in the horizontal movement direction. Therefore, when the top plate 2222 is moved past the shelf, the linkage of the positioning sensing devices 25 of a pair of identification holes 2223 can... To ensure that the latching position 011 of the shelf is not directly above the latching plate 222; for example, when the latching moving plate 221 moves to a position near the shelf, after the front edge of the top plate 2222 passes the shelf in the direction of movement, the positioning sensor 25 of the identification hole 2223 near the edge first passes under the shelf and identifies that the latching position 011 of the shelf is directly above it. The positioning sensor 25 feeds back the positioning information to the X-axis transfer component 23. The X-axis transfer component 23 then moves a specific distance, which is less than the distance between the front and rear identification holes 2223, so that the latching position 011 of the shelf is just between the two identification holes 2223. Similarly, when the top plate 2222 moves excessively, causing the identification hole 2223 near the rear edge of the moving direction to also pass the latching position 011 of the shelf, the positioning sensor 25 near the rear edge recognizes that it has passed the latching position 011 of the shelf. The positioning sensor 25 feeds back the positioning information to the X-axis transfer component 23, and the X-axis transfer component 23 moves a specific distance, which is less than the distance between the front and rear identification holes 2223, so that the latching position 011 of the shelf is just between the two identification holes 2223.

[0054] The position sensing device 25 is a known mechanism capable of recognizing position, such as an infrared recognition device, an industrial camera, or a magnetic position sensing device 25.

[0055] Optimally, it also includes: a grating ruler sensor 26;

[0056] The grating ruler sensor 26 is installed on the receiving base frame 21, and the grating ruler sensor 26 is communicatively connected to the positioning sensing device 25; the grating reading head 261 of the grating ruler sensor 26 is connected to the snap-fit ​​moving plate 221, and the snap-fit ​​moving plate 221 moves synchronously with the grating reading head 261.

[0057] This solution preferably uses a grating ruler sensor 26 to provide the movement reading of the snap-fit ​​moving plate 221. As is generally known, the grating ruler sensor 26 consists of a light source, a converging lens, an indicating grating, a grating reading head 261, a photoelectric element, and an adjustment mechanism. The movement of the grating reading head 261 can detect the movement distance of the snap-fit ​​moving plate 221. Thus, when the position sensing device 25 detects the snap-fit ​​position 011 of the shelf, it can control the X-axis transfer component 23 to move a specific distance. The distance moved can be adjusted in real time according to the reading of the grating reading head 261. If the grating reading head 261 indicates that the movement distance of the snap-fit ​​moving plate 221 is too long, it will be adjusted again, so that the snap-fit ​​position 011 of the shelf is located between the two position sensing devices 25.

[0058] X-axis transfer assembly 23 is a known mechanism with driving and moving functions, such as a trolley, cylinder, hydraulic cylinder, combination of motor and lead screw, conveyor belt structure, etc.

[0059] Optimally, the X-axis transfer assembly 23 includes: an X-axis driven gear 231, an X-axis driving gear 232, an X-axis gear chain 233, and an X-axis driver 234;

[0060] The X-axis driven gear 231 is mounted on the receiving base 21. The X-axis gear chain 233 meshes with multiple X-axis driven gears 231 and is connected to the snap-fit ​​moving plate 221. The X-axis driving gear 232 meshes with the X-axis gear chain 233. The output end of the X-axis driver 234 is connected to the X-axis driving gear 232 and is used to drive the X-axis driving gear 232 to rotate, thereby driving the X-axis gear chain 233 to rotate and driving the snap-fit ​​moving plate 221 to move.

[0061] The X-axis driven gear 231 is mounted on the receiving base frame 21. The X-axis gear chain 233 connects the X-axis driven gear 231 and the X-axis driving gear 232 to rotate synchronously. When the X-axis driver 234 is started, the X-axis driver 234 can drive the X-axis driving gear 232 to rotate, thereby driving the X-axis driven gear 231 to rotate synchronously under the action of the X-axis gear chain 233, thereby causing the X-axis gear chain 233 to rotate, so as to drive the snap-fit ​​moving plate 221 to move back and forth on the transfer track 210.

[0062] The X-axis driver 234 is a known mechanism with a drive rotation function, such as a motor. When the X-axis driver 234 is a motor, the position sensing device 25 can control the position of the latching moving plate 221 in real time by controlling the rotation parameters of the motor.

[0063] Optimally, the X-axis driven gear 231 and the X-axis gear chain 233 are respectively disposed on the left and right sides of the transfer channel 210, and the left and right sides of the snap-fit ​​moving plate 221 are respectively connected to the X-axis gear chain 233; the X-axis driver 234 is a dual-head motor and has output ends on the left and right sides, and the two output ends of the X-axis driver 234 are respectively connected to the X-axis driving gear 232.

[0064] Single-sided drive of the toothed chain may lead to a decrease in drive stability. To address this, this solution preferably uses a double-toothed chain drive direction. The X-axis toothed chains 233 are respectively set on the left and right sides of the transfer channel 210, and the left and right X-axis drive gears 232 are driven to rotate by a dual-head motor. This drives the left and right X-axis toothed chains 233 to rotate simultaneously, thereby synchronously driving the locking moving plate 221 to move at the left and right positions. This increases the pushing force on the shelf. Combined with the bending resistance of the locking component 22, the placement drive of the shelf has stability.

[0065] Optimally, the X-axis transfer assembly 23 includes: an X-axis track 235 and an X-axis slider 236;

[0066] The X-axis track 235 is installed on the transfer channel 210; the X-axis slider 236 is installed on the snap-fit ​​moving plate 221; the X-axis slider 236 is movably installed on the X-axis slider 236.

[0067] The X-axis track 235 extends along the conveying direction of the snap-fit ​​moving plate 221. The snap-fit ​​moving plate 221 can be mounted on the X-axis track 235 via the X-axis slider 236. The movement of the X-axis slider 236 on the X-axis track 235 can provide guidance for the movement of the snap-fit ​​moving plate 221, thereby improving the smoothness of the movement of the snap-fit ​​moving plate 221.

[0068] Optimally, it also includes: a multi-axis transfer assembly 24;

[0069] The multi-axis transfer assembly 24 includes: a Y-axis transfer assembly 242 and a Z-axis transfer assembly 243;

[0070] The X-axis transfer assembly 23 drives the snap-fit ​​moving plate 221 to move horizontally along the X-axis; the output end of the Y-axis transfer assembly 242 drives the receiving base frame 21 to move horizontally along the Y-axis; the output end of the Z-axis transfer assembly 243 drives the receiving base frame 21 to move up and down along the Z-axis.

[0071] The X-axis transfer assembly 23, Y-axis transfer assembly 242, and Z-axis transfer assembly 243 can synchronously drive the snap-fit ​​moving plate 221 to move along the X, Y, and Z axes, thereby transferring the rack to any position in the automated warehouse after receiving the rack, or receiving the rack after moving it to any position in the automated warehouse, thus realizing multi-angle movement of the receiving base frame 21.

[0072] The output end of the Y-axis transfer assembly 242 can be directly or indirectly connected to the receiving base 21; the output end of the Z-axis transfer assembly 243 can be directly or indirectly connected to the receiving base 21. The Y-axis transfer assembly 242 and the Z-axis transfer assembly 243 are known mechanisms with driving and moving functions, such as a moving trolley, a cylinder, a hydraulic cylinder, a combination of a motor and a lead screw, a conveyor belt structure, etc.

[0073] Optimally, it also includes: an inbound identification device 27;

[0074] The inbound identification device 27 is disposed on the left and right sides of the receiving base frame 21 and is located at the front and rear ends of the moving range of the snap-fit ​​moving plate 221; the snap-fit ​​moving plate 221 is located between the left and right inbound identification devices 27; the inbound identification device 27 is communicatively connected to the X-axis transfer assembly 23, the Y-axis transfer assembly 242 and the Z-axis transfer assembly 243.

[0075] When the shelf is about to enter the storage compartment 31, the inbound identification device 27 can scan whether the opening position of the storage compartment 31 is aligned with the receiving base 21 and determine whether the locking moving plate 221 is inside the opening of the storage compartment 31. If so, the X-axis transfer component 23 is controlled to move, driving the locking moving plate 221 to move, so as to take out or send into the shelf. If not, the Y-axis transfer component 242 and the Z-axis transfer component 243 are started to adjust the position of the receiving base 21 until the locking moving plate 221 is inside the opening of the storage compartment 31, thus ensuring the stability of the shelf's picking and placing.

[0076] The warehouse entry identification device 27 is a known mechanism capable of location identification, such as a laser identification device, an industrial camera, or a magnetic positioning sensor.

[0077] A three-dimensional storage system includes: a stacking rack 3 and a rack placement device as described above;

[0078] The stacking rack 3 is provided with several columns and several rows of storage compartments 31; the storage compartments 31 are used to place the shelves; the snap-fit ​​clamps 220 place or remove the shelves from the storage compartments 31 under the action of the X-axis transfer assembly 23.
