Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic sorting and warehousing, and in particular to an automatic weighing elevator system. BACKGROUND

[0002] In the current market, the elevators used in the general sorting industry are mostly limited to basic lifting functions, i.e., only the displacement of materials in the vertical direction is realized, and lack more intelligent and refined management capabilities. These elevators cannot monitor and feedback the weight information of different categories of materials in each storage bin in real time, affecting the efficiency of production scheduling and resource allocation.

[0003] In addition, when the sorting line completes the sorting of goods, if these sorted goods are to be sent to the designated storage bin, the traditional method often needs to rely on additional conveyor belts or other conveying equipment to realize this transfer process. This solution not only increases the complexity and operation and maintenance cost of the system, but also puts high requirements on the operation site, which needs enough space to lay the conveying path to avoid collision and delay of goods during the transfer process.

[0020] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of the present invention will be very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

Figure 2 for Figure 1 Left side view of the embodiment shown, Figure 3 for Figure 1 Right side view of the embodiment shown, Figure 4 for Figure 1 The overall structural diagram of the embodiment shown is as follows, Figure 5 for Figure 1 A partial enlarged view of the cargo lifting frame of the embodiment shown, Figure 6 This is a structural diagram of an embodiment of the temporary storage silo of this application. Figure 7 for Figure 6 Right side view of the embodiment shown. Figures 1 to 7 I understand.

[0022] The automatic weighing elevator system may include a cargo lifting frame 3, a truss 1 and a temporary storage silo 2. A guide rail 7 is vertically arranged on the inner side of the truss 1. The top of the guide rail 7 extends out of the side wall of the truss 1 and is in an arc shape. A cargo lifting frame 3 is arranged on the side of the guide rail 7 away from the truss 1, and a motor 13 is arranged on the other side. An upper sprocket shaft 9 and a lower sprocket shaft 14 are horizontally arranged on the side of the truss 1 close to the guide rail 7. One end of the upper sprocket shaft 9 is sleeved with an upper sprocket 5, and one end of the lower sprocket shaft 14 is sleeved with a lower sprocket 6. The upper sprocket 5 and the lower sprocket 6 are connected by a first chain 8, and the lower sprocket shaft 14 is also sleeved with a first sprocket 10. A second sprocket 12 is sleeved on the output shaft of the motor 13, and the first sprocket 10 and the second sprocket 12 are connected by a second chain 11. The outer side wall of the cargo lifting frame 3 is installed on one side of the first chain 8 to drive the cargo lifting frame 3 to move up and down along the guide rail 7.

[0023] The bottom of the temporary storage bin 2 is provided with a temporary storage bin turnover door 17, and the top end opening of the cargo lifting frame 3 is matched with the temporary storage bin turnover door 17. The temporary storage bin 2 is used to put the cargo into the top end opening of the cargo lifting frame 3 by opening the temporary storage bin turnover door 17. The bottom of the cargo lifting frame 3 is provided with a weighing sensor module, which is used to monitor the weight of the cargo. The hoist system further comprises a main storage bin 4, which is arranged outside the truss 1, and the top end of the guide rail 7 abuts against the feeding port of the main storage bin 4. The temporary storage bin 2 comprises, from top to bottom, a temporary storage bin hopper 15, a temporary storage bin body 16, a temporary storage bin turnover door 17 and a cylinder connecting shaft 18. The temporary storage bin turnover door 17 comprises a bottom plate and a side plate. One end of the bottom plate is connected to the bottom end of the temporary storage bin body 16, and the other end is a free end. One end of the cylinder connecting shaft 18 is connected to the outside of the bottom plate, and the other end is connected to the outside of the temporary storage bin body 16, which is used to drive the temporary storage bin turnover door 17 to open and close.

[0024] Specifically, when the main line is normally operated, the workers or robots on the sorting line automatically put the required cargo into the temporary storage bin 2, and the cargo in the temporary storage bin 2 enters the cargo lifting frame 3. When the weight of the cargo in the temporary cargo lifting frame 3 reaches the set weight, the temporary storage bin turnover door 17 is automatically closed. After the system detects that the temporary storage bin turnover door 17 is closed, the cargo lifting frame 3 starts to detect the weight. After the weight is stable, the system automatically uploads the weight of the cargo in the cargo lifting frame 3 to the system monitoring background. After the data is uploaded, the system starts the power unit to lift the cargo lifting frame 3 to the top. After reaching the top, the specially designed circular arc guide rail 7 is used for overturning, and the cargo in the cargo lifting frame 3 is poured into the main bin. Then the system controls the reverse rotation, and the cargo lifting frame 3 is transported downward. When the system senses that the cargo lifting frame 3 reaches the bottom, the weighing sensor module detects the weight of the cargo, and the temporary storage bin turnover door 17 is opened again for the second cycle of weighing. The above process is repeated.

[0025] In summary, the application adds a temporary storage bin 2 with a turnover door at the bottom, and cooperates with a lifting mechanism with a weighing sensor system, to realize real-time monitoring of the weight of each lifting cargo, and efficiently and accurately transport the sorted cargo to the storage bin. This scheme not only has low cost and convenient installation, but also can monitor the sorting weight of each category in real time, without stopping the line for continuous monitoring, greatly saving the manual weighing process and cost, and optimizing the space utilization, with low requirement for the size of the site.
