[0028] The following description, in conjunction with the accompanying drawings, further illustrates the material loading and unloading silo type of this utility model.

[0029] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0030] See appendix Figure 1-9As shown, the material cart-type three-dimensional loading and unloading silo in this embodiment is characterized by: including a storage cart 1 and a lifting silo 2 that can accommodate the storage cart 1 and is used for loading and unloading materials on the storage cart 1; the storage cart 1 includes a material rack 11, side plates 12 symmetrically arranged on both sides of the material rack 11, a plurality of rolling bearings 13 arranged on the side plates 12, a plurality of material trays 14 slidably connected to the bearings 13, wheels 15 arranged at the bottom of the material rack 11, positioning holes 16 arranged at the bottom of the material rack 11 for connecting with the lifting silo 2, and spring positioning pins 17 arranged on both sides of the material rack 11 for locking the material trays 14; the lifting silo 2 includes a storage bin The frame 21 includes a locking device 22 installed on both sides of the frame 21 for locking the storage cart 1, a horizontal moving mechanism 23 for carrying and moving the material tray 14 horizontally, a lifting device 24 installed on the frame 21 for driving the horizontal moving mechanism 23 to move vertically, several laser sensors 25 installed on both sides of the frame 21 for detecting the material status on the corresponding layer of material tray 14, an indicator light 26 installed on the frame 21 for indicating the material status on the corresponding layer of material tray 14, and a control system 27 installed on the frame 21 and electrically connected to the locking device 22, the horizontal moving mechanism 23, the lifting device 24, the laser sensors 25 and the indicator light 26.

[0031] The material-loaded storage cart 1 is pushed into the lifting chamber 2. The locking device 22 on the lifting chamber 2 locks the storage cart 1, ensuring that the storage cart 1 remains stable within the lifting chamber 2 during loading and unloading. The laser sensor 25, located on the layer corresponding to the material tray 14, detects the material status on the material tray 14 and transmits the information to the control system 27. The control system 27 drives the lifting device 24 to move the horizontal moving mechanism 23 up and down, moving the horizontal moving mechanism 23 to below the material tray 14. The horizontal movement of the horizontal moving mechanism 23 hooks the material tray 14 onto the horizontal moving mechanism 23. The lifting device 24 then raises the horizontal moving mechanism 23 to the loading position, allowing other equipment or operators to retrieve the material from the material tray 14. This process is repeated until all the material on the storage cart 1 is retrieved, and then another storage cart 1 filled with material is used to continue the operation.

[0032] The cooperation between the storage cart 1 and the lifting chamber 2 enables automated material loading and unloading, significantly reducing manpower input, improving work efficiency, and better adapting to the fast-paced demands of industrial production. The locking device 22 and positioning hole 16 ensure the positioning accuracy between the storage cart 1 and the lifting chamber 2. The laser sensor 25 and indicator light 26 enable real-time monitoring of material status and provide prompts, allowing operators to understand the situation promptly. The reasonable coordination of each device makes the loading and unloading process more stable and reliable.

[0033] In one embodiment, the locking device 22 includes a base plate 221 installed at the bottom of the rack 21, a top plate 222 installed on both sides of the rack 21 and located above the base plate 221, a driver 223 installed on the base plate 221, a movable plate 224 connected to the output end of the driver 223, a guide rod 225 passing through the movable plate 224 and fixed between the base plate 221 and the top plate 222, a support column 226 provided on the movable plate 224 for inserting into the positioning hole 16 of the storage trolley 1, and a position sensor 227 provided on the base plate 221 for sensing whether the storage trolley 1 is in position.

[0034] When the storage trolley 1 enters the lifting chamber 2 and reaches the designated position, the position sensor 227 senses the storage trolley 1, and the control system 27 controls the driver 223 to work. The piston rod of the driver 223 drives the movable plate 224 to move upward along the guide rod 225, so that the support column 226 is inserted into the positioning hole 16 of the storage trolley 1, thereby locking the storage trolley 1 in the lifting chamber 2, preventing the storage trolley 1 from shifting during the loading and unloading process, and ensuring the accuracy of the loading and unloading operation.

[0035] When the loading and unloading operations are completed and the storage trolley 1 needs to be moved out of the lifting chamber 2, the control system 27 sends a reverse command to the driver 223. The output end of the driver 223 retracts, pulling the movable plate 224 downward along the guide rod 225. The support column 226 is pulled out from the positioning hole 16, releasing the lock on the storage trolley 1. At this time, the staff can push the storage trolley 1 so that it can drive out of the lifting chamber 2 through the wheels 15.

[0036] In one embodiment, the horizontal moving mechanism 23 includes a support tray 231 parallel to the material tray 14; a drive motor 232 mounted at one end of the support tray 231; a driven wheel 233 disposed at the other end of the support tray 231; a drive wheel 234 connected to the output shaft of the drive motor 232; a transmission belt 235 wound around the drive wheel 234 and the driven wheel 233; a horizontal guide rail 236 disposed on the support tray 231; a slider 237 slidably connected to the horizontal guide rail 236; a claw 238 fixedly connected to the slider 237 for hooking the material tray 14; a clamping block assembly 239 connecting the transmission belt 235 and the claw 238; and a plurality of limiting posts 2310 disposed on the support tray 231 for limiting the position of the material tray 14; and position sensors 227 for detecting the limit of horizontal movement stroke are provided at both ends of the support tray 231.

[0037] When it is necessary to hook the material tray 14, the control system 27 controls the drive motor 232 to work, driving the drive wheel 234 to rotate, which in turn drives the driven wheel 233 to rotate via the transmission belt 235. At the same time, the transmission belt 235 drives the hook 238 to move horizontally along the horizontal guide rail 236 via the clamping block assembly 239. The hook 238 inserts into the hook hole 142 on the material tray 14. At this time, the travel limit at one end has been reached. The position sensor 227 sends a signal to the control system 27, and the control system 27 instructs the drive motor 232 to rotate in the opposite direction, hooking the material tray 14 onto the support tray 231 until the material tray 14 contacts the limit post 2310 and stops, thus realizing the hooking of the material tray 14.

[0038] The cooperation between the horizontal guide rail 236 and the slider 237 provides stable guidance for the movement of the hook 238 and the tray 14, reducing swaying and deviation during the transfer process. The transmission method of the drive wheel 234, driven wheel 233 and transmission belt 235 ensures the uniformity of the movement speed, enabling the tray 14 to be accurately transferred to the target position. The position sensors 227 at both ends of the support tray 231 can effectively detect the stroke limit, preventing the hook 238 and the tray 14 from colliding or falling off due to excessive movement, ensuring the safety of the equipment and materials. The limit post 2310 further restricts the position of the tray 14 on the support tray 231 to prevent the tray 14 from slipping.

[0039] In one embodiment, the lifting device 24 includes fixed plates 241 mounted on both sides of the rack 21, a second drive motor 242 mounted on the side of the pallet 231, a gear 243 mounted on the output shaft of the second drive motor 242, a rack 244 mounted on the fixed plate 241 and meshing with the gear 243, an auxiliary gear shaft 247 passing through both sides of the pallet 231 and meshing with the rack 244, a plurality of vertical guide rails 245 mounted on the fixed plate 241, and a second slider 246 mounted on both sides of the pallet 231 and slidably connected to the vertical guide rails 245. Position sensors 227 are provided at the upper and lower ends of the fixed plate 241 for detecting the limits of the vertical travel of the horizontal moving mechanism 23.

[0040] When the horizontal moving mechanism 23 needs to be moved to a designated height, the control system 27 controls the drive motor 242 to operate, driving the gear 243 to rotate. Since the gear 243 meshes with the rack 244 on the fixed plate 241, and the auxiliary gear shaft 247 passing through both sides of the support tray 231 also meshes with the rack 244, under the transmission action of the gear 243 and rack 244, the sliders 246 on both sides of the support tray 231 move vertically along the vertical guide rail 245, thereby driving the horizontal moving mechanism 23 to rise and fall as a whole. During the vertical movement, the position sensors 227 at both ends of the fixed plate 241 monitor the position of the horizontal moving mechanism 23 in real time. When the horizontal moving mechanism 23 approaches its upper or lower travel limit, the corresponding position sensor 227 sends a signal to the control system 27, and the control system 27 immediately instructs the drive motor 242 to stop operating to prevent the mechanism from overtraveling.

[0041] When the horizontal moving mechanism 23 reaches the target height, the control system 27 controls the drive motor 242 to stop working according to the preset program or feedback signal, and the gear 243 and auxiliary gear shaft 247 to stop rotating. The horizontal moving mechanism 23 stops precisely at that height so that the subsequent material tray 14 can be transferred.

[0042] Through the double meshing transmission of gear 243, auxiliary gear shaft 247 and rack 244, combined with the guiding effect of vertical guide rail 245 and slider 246, the stability of vertical movement of horizontal moving mechanism 23 is greatly improved, shaking is reduced, and the material tray 14 remains stable during lifting.

[0043] In one embodiment, the tray 14 is provided with a positioning groove 141 adapted to the spring positioning pin 17 and a hook hole 142 for the hook 238 of the horizontal moving mechanism 23 to be inserted.

[0044] When the tray 14 needs to be installed onto the rack 11 of the storage cart 1, the operator pushes the tray 14 from the rear of the rack 11 along the bearing 13 on the side plate 12 into the rack 11. During the pushing process, the bottom of the tray 14 will press against the spring positioning pin 17, causing the spring positioning pin 17 to compress and contract. When the tray 14 moves to the appropriate position and the positioning groove 141 aligns with the spring positioning pin 17, the spring positioning pin 17 pops out under the action of the spring force and accurately locks into the positioning groove 141, firmly locking the tray 14 onto the rack 11 and preventing the tray 14 from sliding during the movement of the storage cart 1 or during loading and unloading. When it is necessary to remove the tray 14, the operator lifts the tray 14 to disengage the spring positioning pin 17 from the positioning groove 141, then pulls the tray 14 to make the spring positioning pin 17 misalign with the positioning groove 141, and then lowers the tray 14 so that the bottom of the tray 14 presses against the spring positioning pin 17, causing the spring positioning pin 17 to compress and retract, and the tray 14 can be easily slid out along the bearing 13.

[0045] When the horizontal moving mechanism 23 needs to hook the material tray 14, the lifting device 24 first adjusts the support tray 231 to a height flush with the material tray 14; then, the drive motor 232 of the horizontal moving mechanism 23 starts, driving the hook 238 to move along the horizontal guide rail 236 towards the material tray 14 via the transmission belt 235; during the movement, the hook 238 is precisely aligned with the hook hole 142 on the material tray 14 and gradually inserted into the hook hole 142; when the hook 238 is fully inserted into the hook hole 142, the lifting device 24 brings the horizontal moving mechanism 23 to a height that is flush with the material tray 14. When mechanism 23 moves upward, horizontal moving mechanism 23 drives material tray 14 upward, causing spring positioning pin 17 to disengage from positioning groove 141. Drive motor 232 rotates in the opposite direction, and hook 238 drives material tray 14 to move towards support tray 231. After spring positioning pin 17 is no longer aligned with positioning groove 141, lifting device 24 returns to the position where horizontal moving mechanism 23 hooks material tray 14, lowers material tray 14 to be parallel to support tray 231, and then continues to start drive motor 232 to rotate in the opposite direction to realize hooking and transferring of material tray 14.

[0046] In one embodiment, mounting plates 211 for mounting laser sensors 25 are provided on both sides of the rack 21 and on the outside of the side plate 12; the mounting plates 211 and the side plate 12 of the storage cart 1 are provided with through holes 121 for the laser sensor 25 beam to pass through to detect the material on the tray 14.

[0047] The laser sensor 25 is installed on the mounting plate 211 according to the position of the corresponding material tray 14, and the transmitting end and receiving end of the laser sensor 25 are aligned with the positions of the through holes 121 on the mounting plate 211 and the side plate 12, so that the laser can pass smoothly through the through holes 121 to detect the material on the material tray 14 and transmit the detected information to the control system 27.

[0048] If there is material on the tray 14, the laser beam is blocked by the material, and the receiver of the laser sensor 25 cannot receive the laser signal; if there is no material on the tray 14, the laser beam can pass through smoothly, and the receiver can receive the laser signal.

[0049] In one embodiment, the bottom of the rack 21 is also equipped with wheels 15; this facilitates the movement of the lifting bin 2, improves the flexibility of the equipment, and allows it to be flexibly adjusted in position according to production needs.

[0050] In one embodiment, the pallet 231 is also provided with a plurality of rolling bearings 13 for supporting the tray 14; the tray 14 slides on the bearings 13, so that the horizontal moving mechanism 23 can hook the tray 14.

[0051] In one embodiment, the actuator 223 is a pneumatic hydraulic cylinder, an electric hydraulic cylinder, or an electric actuator.

[0052] In the process of using this utility model, the operator neatly places the material to be processed on the material tray 14, and then pushes the material tray 14 into the material rack 11 along the bearing 13 on the side plate 12 of the storage cart 1. During the pushing process, the bottom of the material tray 14 compresses the spring positioning pin 17 to make it retract. When the material tray 14 is in place and the positioning groove 141 is aligned with the spring positioning pin 17, the spring positioning pin 17 pops out and locks into the positioning groove 141, thus fixing the material tray 14. Repeat the operation to load multiple material trays 14 onto the storage cart 1 in layers.

[0053] The operator pushes the storage cart 1 with the material tray 14 and smoothly drives it into the bin frame 21 of the lifting bin 2 through the bottom wheels 15 until the storage cart 1 reaches the preset stopping position. At this time, the positioning hole 16 at the bottom of the storage cart 1 is roughly aligned with the support column 226 of the locking device 22 of the lifting bin 2.

[0054] After the control system 27 detects that the storage car 1 is in place, it sends a command to the locking device 22. The driver 223 of the locking device 22 is activated. The output end of the driver 223 pushes the movable plate 224 to rise along the guide rod 225, so that the support column 226 is accurately inserted into the positioning hole 16 of the storage car 1, and the storage car 1 is firmly locked in the silo frame 21 to prevent displacement during subsequent operations.

[0055] When the laser sensors 25 on the mounting plates 211 on both sides of the rack 21 are activated, the laser beam shines through the through holes 121 on the mounting plates 211 and the side plates 12 onto the corresponding material tray 14. The laser sensors 25 transmit the detected material presence, quantity and other status information to the control system 27. The control system 27 controls the indicator lights 26 on the corresponding layer of the rack 21 to light up according to the information. For example, a green light indicates that there is material waiting to be processed, and a red light indicates that the material has been processed.

[0056] According to the indicator light 26 and production requirements, the control system 27 instructs the lifting device 24 to work, and the second drive motor 242 drives the gear 243 to rotate. The gear 243 meshes with the rack 244 on the fixed plate 241, and at the same time, the auxiliary gear shaft 247 cooperates to transmit the transmission, so that the pallet 231 moves vertically along the vertical guide rail 245 through the second slider 246 until the pallet 231 moves below the target material tray 14. The position sensor 227 at the upper and lower ends of the fixed plate 241 monitors the movement stroke in real time to prevent overtravel.

[0057] The drive motor 232 of the horizontal moving mechanism 23 starts, and the driving wheel 234 drives the driven wheel 233 to rotate via the transmission belt 235. The hook 238 moves along the horizontal guide rail 236 with the slider 237 towards the material tray 14, accurately inserting into the hook hole 142 of the material tray 14. After the hook 238 is fully inserted into the hook hole 142, the lifting device 24 moves the horizontal moving mechanism 23 upward. The horizontal moving mechanism 23 drives the material tray 14 upward, causing the spring positioning pin 17 to disengage from the positioning groove 141. The drive motor 232 rotates in the opposite direction, and the hook 238 drives... The material tray 14 moves toward the support tray 231. After the spring positioning pin 17 is not aligned with the positioning groove 141, the lifting device 24 returns to the position where the horizontal moving mechanism 23 hooks the material tray 14, and the material tray 14 is lowered to be parallel to the support tray 231. Then, the drive motor 232 is started to rotate in the opposite direction. The hook 238 drives the material tray 14 back to the support tray 231. The bearing 13 on the support tray 231 assists in supporting the material tray 14. The limit post 2310 limits the position of the material tray 14. The position sensors 227 at both ends of the support tray 231 prevent the hook 238 from overtraveling.

[0058] The lifting device 24 drives the pallet 231 to move to the designated processing position. After the material processing is completed, the pallet 14 is sent back to the original layer.

[0059] After all the material trays 14 on the storage cart 1 have finished loading and unloading, the control system 27 instructs the driver 223 of the locking device 22 to reset, the support column 226 exits from the positioning hole 16, and the locking of the storage cart 1 is released; the operator pushes the storage cart 1 to move it out of the lifting chamber 2, and all parts of the equipment are reset under the action of the control system 27, waiting for the next operation.
