[0049] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0050] As Figures 1 to 7As shown in the figure, the special-shaped elevator includes a lifting device 1. The bottom of the lifting device 1 is an inclined lifting part 11, and the top is a vertical lifting part 12. The outer surfaces of the inclined lifting part 11 and the vertical lifting part 12 are provided with the same transmission track 14. The transmission track 14 is driven to rotate by a GK series reducer with a power of 3KW in cooperation with gears. The transmission and operation modes of the transmission track 14 use the existing technology and are not modified in this application.

[0051] A support plate 13 is further provided outside the transmission track 14. The support plate 13 is installed on the track link 15 of the transmission track 14, and there are multiple support plates 13. The support plate 13 is installed on the track link 15, and the support plate 13 rotates with the track in a cycle. It carries the items to be lifted at the bottom, unloads the items to be lifted after reaching the top from one side of the transmission track 14, and then returns to the bottom from the other side of the track, repeating the cycle.

[0052] A first roller line 16 is provided inside the support plate 13. The top of the roller of the first roller line 16 is higher than the upper surface of the support plate 13. The setting of the roller line facilitates the first pushing machine 4 to push the items to be lifted onto the support plate 13, replacing sliding friction with rolling friction.

[0053] The included angle between the inclined lifting part 11 and the horizontal plane ranges from 65° to 85°, and the included angle between the vertical lifting part 12 and the horizontal plane is 90°. The support plate 13 is perpendicular to the transmission track 14.

[0054] Preferably, the included angle between the inclined lifting part 11 and the horizontal plane is 75°, and the included angle between the vertical lifting part 12 and the horizontal plane is 90°. The setting of the inclined lifting part 11 is used to increase the contact area between the items to be lifted and the transmission track 14, improving the safety during the lifting process. The setting of the vertical lifting part facilitates the vertical pushing out of the items to be lifted by the second pushing machine 6. The original setting direction of the lifting device is perpendicular to the horizontal plane, and due to the bumps during transportation, it is easy to cause falling. In this application, during the lifting process, the items to be lifted lean towards the transmission track direction, and at the same time, the center of the entire item to be lifted is close to the transmission track, improving the stability during transportation.

[0055] On the side of the bottom of the lifting device 1 for feeding, there is also a compensation device 2. The compensation device 2 includes a support frame 24 and a U-shaped lever 21. One end of the U-shaped lever 21 is a hinge part 22 and the other end is a movable part 23. The U-shaped lever 21 is hinged to the support frame 24 through the hinge part 22. At the bottom of the U-shaped lever 21, there is also a cylinder connected. One end of the cylinder is connected to the support frame 24 and the other end is connected to the U-shaped lever 21. The cylinder is used to push and pull the U-shaped lever 21 to realize the lifting of the movable part 23; the setting of the compensation device 2 is beneficial to improving the working efficiency of the machine. Under normal circumstances, the first pusher 4 is used to push the item to be lifted from the third roller line 3 onto the pallet 13, which requires the push rod of the first pusher 4 to extend too long, reducing the working efficiency of the machine. After setting the compensation device 2, the first pusher 4 only needs to push the item to be lifted to the U-shaped lever 21 of the compensation device 2. The cylinder arranged under the U-shaped lever 21 is used to push the movable part 23 of the U-shaped lever 21 to lift and pull the item to be lifted towards the lifting device 1 side, assisting the first pusher 4 to complete the pushing action, shortening the extension distance of the push rod of the first pusher 4. The cooperation between the first pusher 4 and the compensation device 2 is beneficial to improving the working efficiency of the machine.

[0056] On the support frame 24, there is also a second roller line, and the top of the rollers of the second roller line is higher than the upper surface of the support frame 24;

[0057] The arrangement direction of the first roller line 16 and the second roller line is perpendicular to each other. The second roller line is inclined, and the height of the end of the second roller line close to the lifting device 1 is lower than that of the other end.

[0058] There is also a correction device 5. The correction device 5 is arranged on both sides of the compensation device 2 in sequence along the length direction of the rollers in the first roller line 16. The correction device 5 includes a correction bracket 53 and a correction arm 52. The bottom of the correction bracket 53 is erected on both sides of the third roller line 3. The top of the correction bracket 53 extends towards the lifting device 1 to form a correction beam 51 above the compensation device 2, and there are multiple correction beams 51;

[0059] Below one end of the multiple correction beams 51 close to the lifting device 1, there are cylinders arranged in the reverse direction;

[0060] There are two correction arms 52. The upper ends of the two correction arms 52 are connected to the output ends of the two cylinders arranged in the reverse direction, and the lower ends of the correction arms 52 hang down to both sides of the compensation device 2.

[0061] The correction device 5 is used to adjust the position of the item to be lifted, hold the item to be lifted tightly through the correction arm 52, and adjust the item to be lifted to the centered position on the pallet 13.

[0062] On the side of the compensation device 2 away from the lifting device 1, a third roller line 3 and a first pusher 4 are sequentially provided. The third roller line 3 is arranged between the compensation device 2 and the first pusher 4;

[0063] The third roller line 3 is arranged along the length direction of the rollers in the first roller line 16;

[0064] The third roller line 3 is used to convey the items to be lifted to one end of the third roller line 3 close to the compensation device 2. An elevating baffle is also provided below the third roller line 3, and the elevating baffle is used to limit the items to be lifted transported through the third roller line 3;

[0065] The first pusher 4 is used to push the items to be lifted on the third roller line 3 onto the compensation device 2.

[0066] On both sides of the vertical lifting part 12, a second pusher 6 and a loading line row 7 are also provided. The width of the item to be lifted is greater than the width of the pallet 13, and both ends of the item to be lifted extend outside the pallet 13; There are two second pushers 6, which are respectively arranged behind the parts where both ends of the item to be lifted extend outside the pallet 13. The second pusher 6 is used to push the item to be lifted lifted by the pallet 13 onto the loading line row 7. Since the width of the item to be lifted is greater than the width of the pallet 13, both sides of the item to be lifted extend outside the pallet 13, and the second pusher 6 completes the unloading operation of the pallet 13 by pushing the part of the item to be lifted extending outside the pallet 13.

[0067] The first pusher 4 and the second pusher 6 are arranged on both sides of the lifting device 1.

[0068] There are two loading line rows 7, and roller lines are arranged along the length direction of each loading line row 7;

[0069] At the bottom of each loading line row 7, a lifting cylinder for adjusting the height is provided;

[0070] A reserved lane is provided between the two loading line rows 7. When the goods are stacked full on the loading line row 7, control the lifting cylinder to descend. There is a transport vehicle in the reserved lane. When the height of the loading line row 7 is lowered to be lower than the height of the transport vehicle, the loading step of the item to be lifted is completed. An induction element can be installed at the end of the loading line row 7 to sense whether the line row is full. After it is full, start a buzzer to remind the staff to transport the item to be lifted away by the transport vehicle in time.

[0071] In the specific implementation process, a box anti-side slip device 8 and an equipment protection device 9 are also included. The anti-side slip device 8 includes limit beams arranged on both sides of the pallet to prevent the items to be lifted from slipping sideways. The limit beams are installed on the brackets on both sides of the lifting device; The equipment protection device 9 includes a protective net arranged in the equipment working area.

[0072] The special-shaped elevator is set with a floor jump. In another embodiment, by lowering the lifting baffle described in the previous embodiment to close the lifting device 1, the items to be lifted transported by the third roller line 3 are conveyed to the other end of the third roller line 3 through the position of the lifting baffle. At the same time, a bag pusher and a loading line row are arranged on both sides of the end of the other end of the third roller line 3, and a transport cart is arranged under the loading line row.

[0073] In the specific implementation process, one end of the third roller line 3 is connected to the assembly production line. The produced products are boxed and transported away through the third roller line 3. Two conveying and storage methods are realized by adjusting the raising and lowering of the lifting baffle: One method is to raise the lifting baffle, start the lifting device 1 and its related devices to convey the products to the second floor, and cooperate with the second bag pusher 6 and the transport cart arranged under the loading line row 7 on the second floor to transport the products conveyed to the second floor to the warehouse for storage; Another method is to lower the lifting baffle, convey the products to the end of the third roller line 3 far from the assembly production line, and arrange a bag pusher and a loading line row on both sides of the end. At the same time, a transport cart is arranged under the loading line row to transport the products to the warehouse on the first floor for storage.

[0074] In another embodiment, the operation of each device and component in the special-shaped elevator described in this application is controlled by a PLC. The motor of the transmission track 14 in the lifting device 1 of the special-shaped elevator, the motor driving the third roller line 3 to rotate, the cylinder driving the lifting baffle, the cylinder driving the U-shaped lever 21 in the compensation device 2, the first bag pusher 4, the second bag pusher 6, the cylinder driving the correction arm 52, and the lifting cylinder arranged under the loading line row 7 are all connected to the PLC and controlled by the PLC. At the same time, sensors are arranged on the third roller line 3 and the lifting device 1. The sensors and the PLC use existing products. This application only uses the functions that can be realized by their disclosed technologies. The sensors are connected to the PLC. In the specific implementation process, multiple sensors cooperate with the PLC to achieve the following functions:

[0075] The sensor on the third roller line 3 is used to sense that there is a newly transported product on the third roller line 3, and convey the sensing signal to the PLC. The PLC controls the lifting device 1 to transport the pallet 13 to the working position and stop.

[0076] After the product is pushed onto the pallet by the first bag pusher and the compensation device, after the sensor installed on the lifting device 1 senses that the product is placed on the pallet, the sensing signal is sent back to the PLC, and then the transmission track of the lifting device 1 continues to operate.

[0077] There is also a sensor at the top of the lifting device 1. During normal operation, the products conveyed to the top are pushed out by the second bag pusher. When a failure occurs and the products are not pushed out normally, when they are lifted to the top of the lifting device 1 by the pallet, the sensor transmits the signal back to the PLC, thereby controlling the emergency braking of the entire device and sounding a horn to prompt the on-site staff. The PLC circuit diagram of the entire device is as shown in Figure 8 shown.

[0078] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
