[0002] At present, when sorting plastic bottles, sorting centers usually set up plastic bottle storage silos to increase production and improve efficiency, and then transport them to optical sorting machines through screw conveyors, thereby realizing automatic and fine sorting of plastic bottles.

[0003] However, the problem with the related technology is that, on the one hand, the conical part of the plastic bottles in the storage bin is prone to arching and bridging, which makes the conical surface easy to block the material and slow down the material discharge; on the other hand, due to the structural limitations of the screw conveyor, continuous feeding cannot be achieved. The screw conveyor in the related technology is only feeding for one-third of the time and is idle for two-thirds of the time. All these have seriously affected the actual production capacity of the optical sorting machine. Summary of the invention

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following describes a feeding control method for an intelligent sorting device, a computer-readable storage medium, a feeding control device for an intelligent sorting device, and an intelligent sorting device according to an embodiment of the present invention with reference to the accompanying drawings.

[0035] Figure 1 It is a schematic diagram of the structure of an intelligent sorting device according to a specific embodiment of the present invention.

[0036] Specifically, in some embodiments of the present invention, Figure 1 As shown, the intelligent sorting equipment 2000 includes a material storage bin 100, a belt conveyor 200 and an optical sorter 300. The inlet end of the belt conveyor 200 is arranged at the lower end of the outlet of the material storage bin 100. The inlet end of the optical sorter 300 is connected to the outlet end of the belt conveyor 200. The material storage bin 100 includes a pneumatic arch breaking device 1001 and a pneumatic valve 1002 arranged at the outlet of the material storage bin 100. Specifically, as shown in FIG. Figure 1 As shown, the outlet of the material storage bin 100 is in the shape of a cone with four closed sides, and a pneumatic valve 1002 driven by a cylinder is provided at the outlet of the material storage bin 100. The gas valve 1001 is specifically used to adjust the material discharge flow of the logistics storage bin 100. At the same time, in order to solve the problem that the material is prone to arching and cannot be discharged at the outlet of the material storage bin 100, a pneumatic arch breaking device 1001 is added to destroy the bridging state of the material, ensuring that the material can fall normally onto the belt conveyor 200 located at the bottom of the material storage bin 100, and then, the material is transported to the optical sorting machine 300 for material sorting by the belt conveyor 200.

[0037] Optionally, in the above embodiments of the present invention, the material may be a plastic bottle or other recyclable renewable resources.

[0038] Figure 2 It is a flow chart of a feeding control method of an intelligent sorting device according to an embodiment of the present invention.

[0039] Specifically, in some embodiments of the present invention, Figure 2 As shown, the feeding control method of the intelligent sorting equipment includes:

[0040] S101, when the intelligent sorting equipment is started, the pneumatic valve is controlled to open to the half-open position.

[0041] It can be understood that in this embodiment of the present invention, a proximity switch is provided on the cylinder, wherein the proximity switch is pre-adjusted to a half-open door position. For example, when the intelligent sorting equipment is started, the pneumatic valve 1002 starts to move by driving the cylinder until the cylinder reaches the proximity switch. At this time, the pneumatic valve 1002 will automatically stop at the half-open door position, and the material storage bin 100 starts to discharge materials.

[0042] S102, obtaining the material discharge flow rate of the material storage bin, and adjusting the opening of the pneumatic valve according to the material discharge flow rate of the material storage bin.

[0043] It is understandable that in this embodiment of the present invention, the material discharge flow rate of the material storage bin 100 can be monitored in real time to automatically adjust the opening of the pneumatic valve 1002 according to the real-time changes in the material discharge flow rate, thereby maintaining the material discharge relatively stable.

[0044] For example, in this embodiment of the present invention, if the material unloading flow rate of the material storage bin 100 is less than the preset flow rate threshold, it can be considered that the material unloading flow rate is too small. At this time, the opening of the pneumatic valve 1002 is adjusted to increase the material unloading flow rate. Conversely, if the material unloading flow rate of the material storage bin 100 is greater than or equal to the preset flow rate threshold, it can be considered that the material unloading flow rate is normal. At this time, the opening of the pneumatic valve 1002 is kept unchanged to ensure that the material unloading flow rate is relatively stable.

[0045] S103, when it is detected that the material discharge flow rate of the material storage bin has not changed, the pneumatic arch breaking device is controlled to perform the arch breaking action.

[0046] It can be understood that in this embodiment of the present invention, the size of the discharge port of the material storage bin 100 can be adjusted by adjusting the opening of the pneumatic valve 1002 through the pneumatic control system 1003. Therefore, when it is detected that the discharge flow rate of the material storage bin 100 has not changed, it is considered that the material may have arched and bridged in the material storage bin 100. At this time, the pneumatic arch breaking device 1001 is controlled to perform an arch breaking action to destroy the arching and bridging phenomenon, thereby ensuring that the material falls normally onto the belt conveyor 200 at the bottom of the material storage bin 100.

[0047] Specifically, in the above-mentioned embodiment of the present invention, based on the feeding control method of the intelligent sorting equipment proposed in the embodiment of the present invention, on the one hand, by adjusting the opening of the pneumatic valve 1002 at the outlet of the material storage bin 100, the material discharge flow rate of the material storage bin 100 is accurately controlled; on the other hand, a pneumatic arch breaking device 1001 is used to solve the problem of poor material discharge, keep the material flow relatively stable, and give full play to the production capacity of the optical sorting machine 300, thereby improving the sorting efficiency and output of plastic bottles.

[0048] Further, in some embodiments of the present invention, Figure 3 As shown, the material unloading flow of the material storage bin is obtained, including:

[0049] S201, obtaining the net weight difference of the material storage bin within a preset time period.

[0050] Specifically, in some embodiments of the present invention, the method further includes: obtaining net weight data of the material storage bin 100 through a weighing sensor, and obtaining a net weight difference of the material storage bin 100 within a preset time period based on the net weight data of the material storage bin 100.

[0051] It can be understood that in this embodiment of the present invention, during the unloading process of the material storage bin 100, the net weight data of the remaining material is sensed in real time by the weighing sensors 1004 installed at the four corners of the material storage bin 100, and then the net weight difference of the material storage bin 100 within a preset time period is obtained.

[0052] S202, obtaining the material discharge flow rate of the material storage bin according to the net weight difference.

[0053] It is understandable that, in this embodiment of the present invention, the material discharge flow rate of the material storage bin 100 can be calculated by comparing the net weight difference before and after a fixed time period (ie, the net weight difference of the material storage bin 100 within a preset time period).

[0054] Optionally, in the above-mentioned embodiment of the present invention, the material flow rate of the material storage bin 100 can be monitored in real time by installing a sensor on the belt conveyor 200 to monitor the material flow height, or by monitoring the number of material discharges through a camera.

[0055] Furthermore, in some embodiments of the present invention, the pneumatic arch breaking device includes an air storage bag and multiple pulse pneumatic valves, and controlling the pneumatic arch breaking device to perform the arch breaking action includes: controlling the multiple pulse pneumatic valves to open cyclically, and blowing the materials in the material storage bin through compressed air pulses.

[0056] It can be understood that in order to avoid the arching and bridging of materials in the material storage bin 100, and the situation where the material discharge flow rate of the material storage bin 100 cannot be increased by opening the pneumatic valve 1002, in this embodiment of the present invention, multiple pulse pneumatic valves are controlled to open cyclically, and the materials in the material storage bin 100 are sprayed with compressed air pulses, thereby destroying the arching and bridging phenomenon of the materials and ensuring the normal discharge of the materials.

[0057] Optionally, in this embodiment of the present invention, each pulse pneumatic valve can also correspond to multiple blowing nozzles, or an annular blowing pipe can be set inside the cone, and multiple pulse pneumatic valves can be controlled to open cyclically at preset intervals to avoid arching and bridging of materials in the material storage bin 100.

[0058] Further, in some embodiments of the present invention, Figure 1 As shown, enclosures are provided on both sides of the belt conveyor 200 , and a flow limiting gate 2001 is provided at the outlet of the belt conveyor 200 .

[0059] It can be understood that due to the poor fluidity of the material itself, after the pneumatic arch-breaking device 1001 is controlled to perform the arch-breaking action, the material pile will collapse instantly when the arch state of the material is destroyed. At this time, if the pneumatic valve 1002 happens to be at a large opening, the discharge flow of the material storage bin 100 will be too large. Therefore, in this embodiment of the present invention, enclosures are provided on both sides of the belt conveyor 200 to temporarily store part of the material when the discharge flow of the material storage bin 100 becomes instantaneous. In addition, the belt conveyor 200 is always running, and the accumulated materials will be transported to the outlet of the belt conveyor 200 along with the belt. At this time, the discharge flow of the belt conveyor 200 is controlled by the flow limiting gate 2001 provided at the outlet of the belt conveyor 200, wherein the flow limiting gate 2001 is a mechanical limit device, and the discharge flow of the belt conveyor 200 can be controlled by adjusting its height, so that the discharge flow of the belt conveyor 200 matches the production capacity of the optical sorting machine 300.

[0060] Optionally, in the above-mentioned embodiment of the present invention, the method of using a fence to buffer materials and using a flow-limiting gate 2001 to control the discharge flow rate of the belt conveyor 200 is only one of the lower-cost implementation methods. In addition, the motor speed can be controlled by adding a frequency converter to adjust the belt speed of the belt conveyor 200 to control the discharge flow rate.

[0061] It should be noted that in some embodiments of the present invention, the height of the current limiting gate 2001 can be adjusted in advance to a height that matches the current production capacity of the optical sorter 300, so that the discharge flow of the belt conveyor 200 matches the current production capacity of the optical sorter 300.

[0062] Further, in some embodiments of the present invention, Figure 4 As shown, the feeding control method of the intelligent sorting equipment also includes:

[0063] S301, obtaining the maximum production capacity of the optical sorting machine.

[0064] It is understandable that, in this embodiment of the present invention, the maximum capacity of the optical sorter 300 can be determined based on the working parameters of the optical sorter 300 (for example, the high-speed belt speed of the optical sorter, etc.).

[0065] S302, obtaining a target discharge flow rate of the belt conveyor according to the maximum capacity of the optical separator.

[0066] It can be understood that in this embodiment of the present invention, the maximum production capacity of different optical sorters 300 corresponds to the target discharge flow rate of different belt conveyors 200. Therefore, the target discharge flow rate of the matching belt conveyor 200 can be determined based on the maximum production capacity of the current optical sorter 300.

[0067] S303, adjusting the height of the flow-limiting gate according to the target discharge flow rate of the belt conveyor.

[0068] It can be understood that in this embodiment of the present invention, the height of the flow limiting gate 2001 can be automatically adjusted according to the target discharge flow rate of the belt conveyor 200 that matches the current maximum production capacity of the optical sorting machine 300, so that the actual discharge flow rate of the belt conveyor 200 reaches the target discharge flow rate, thereby matching the discharge flow rate of the belt conveyor 200 with the production capacity of the optical sorting machine 300.

[0069] Further, in some embodiments of the present invention, Figure 1 As shown, the intelligent sorting equipment 2000 also includes a vibrating feeder 400, and the method further includes: controlling the vibrating feeder to evenly spread the material after the flow of the belt conveyor is limited laterally.

[0070] It can be understood that the optical sorting machine 300 is composed of a high-speed belt conveyor 3001, an image recognition module 3002 and a spray sorting device. The high-speed belt conveyor 3001 can further open the front and rear spacing of relatively uniform plastic bottles to avoid material stacking affecting identification and sorting. However, since the width of the optical sorting machine 300 is usually larger than the width of the high-speed belt conveyor 3001, in order to give full play to the effective width of the high-speed belt, in this embodiment of the present invention, it is necessary to feed the roughly uniform material (for example, plastic bottles) conveyed by the belt conveyor 200 to the high-speed belt conveyor 3001 after the vibrating feeder 400 disperses the material evenly again horizontally, so as to achieve the following effect. Figure 5 The saturated feeding effect is shown to maximize the production capacity of the optical sorter 300.

[0071] Optionally, in some embodiments of the present invention, the method further includes: after controlling the pneumatic arch breaking device to perform the arch breaking action, if the material discharge flow rate of the material storage bin has not changed, controlling the pneumatic arch breaking device to continue to perform the arch breaking action until the material discharge flow rate of the material storage bin changes.

[0072] It can be understood that in this embodiment of the present invention, when the pneumatic arch breaking device 1001 is controlled to perform the arch breaking action, the material discharge flow rate of the material storage bin 100 does not change, it can be considered that the material in the material storage bin 100 is seriously blocked. At this time, the pneumatic arch breaking device 1001 is controlled to continue to perform the arch breaking action (for example, perform multiple arch breaking actions) until the material discharge flow rate of the material storage bin 100 changes (that is, the blockage situation is improved), and the pneumatic arch breaking device 1001 is controlled to stop the arch breaking action.

[0073] Specifically, in the above-mentioned embodiment of the present invention, compared with the large-opening storage bin combined with the screw conveyor in the prior art, the problem of the intermittent and discontinuous material flow of the screw conveyor is solved, and the production capacity of the optical sorting machine 300 can be maximized. The optical sorting machine 300 adopts jet sorting and is equipped with an air compressor. At the same time, the pneumatic arch breaking device 1001 and the cylinder gas consumption directly use the air source of the optical sorting machine 300. The power of the belt conveyor 200 is only 1.5kW, which is much lower than the 4kW of the screw conveyor, and the energy-saving effect is significant.

[0074] In summary, according to the feeding control method of the intelligent sorting equipment of the embodiment of the present invention, when the intelligent sorting equipment is started, the pneumatic valve is controlled to open to the half-open door position, and then, the material discharge flow rate of the material storage bin is obtained, and the opening of the pneumatic valve is adjusted according to the material discharge flow rate of the material storage bin, and when it is detected that the material discharge flow rate of the material storage bin has not changed, the pneumatic arch breaking device is controlled to perform the arch breaking action. Thus, by adjusting the opening of the pneumatic valve at the outlet of the material storage bin, the material discharge flow rate of the material storage bin is accurately controlled, and pneumatic arch breaking is used to solve the problem of poor material discharge, so as to keep the material flow relatively stable and give full play to the production capacity of the optical sorting machine, thereby improving the sorting efficiency and output of plastic bottles.

[0075] Based on the feeding control method of the intelligent sorting equipment in the aforementioned embodiment of the present invention, the embodiment of the present invention further proposes a computer-readable storage medium, on which a feeding control program of the intelligent sorting equipment is stored. When the feeding control program of the intelligent sorting equipment is executed by the processor, the feeding control method of the intelligent sorting equipment in the aforementioned embodiment of the present invention is implemented.

[0076] It should be understood that the specific implementation of the computer-readable storage medium of the embodiment of the present invention can refer to the specific implementation of the feeding control method of the intelligent sorting equipment of the aforementioned embodiment of the present invention, and will not be repeated here to reduce redundancy.

[0077] In summary, according to the computer-readable storage medium of an embodiment of the present invention, by executing the feeding control program of the intelligent sorting equipment stored thereon, it is possible to maintain a relatively stable material flow and give full play to the production capacity of the optical sorting machine, thereby improving the sorting efficiency and output of plastic bottles.

[0078] Figure 6 Schematic diagram of a feeding control device of an intelligent sorting device according to an embodiment of the present invention.

[0079] Specifically, in some embodiments of the present invention, Figure 6 As shown, the feeding control device 1000 of the intelligent sorting equipment includes: a control module 10, an adjustment module 20 and an arch breaking module 30.

[0080] Among them, the control module 10 is used to control the pneumatic valve to open to a half-open position when the intelligent sorting equipment is started; the adjustment module 20 is used to obtain the unloading flow of the material storage bin, and adjust the opening of the pneumatic valve according to the unloading flow of the material storage bin; the arch breaking module 30 is used to control the pneumatic arch breaking device to perform the arch breaking action when it is detected that the unloading flow of the material storage bin has not changed.

[0081] Furthermore, in some embodiments of the present invention, the regulating module 20 is also used to obtain the net weight difference of the material storage bin within a preset time period; and obtain the material discharge flow rate of the material storage bin according to the net weight difference.

[0082] Furthermore, in some embodiments of the present invention, the pneumatic arch breaking device includes an air storage bag and multiple pulse pneumatic valves. The arch breaking module 30 is also used to control the cyclic opening of the multiple pulse pneumatic valves to spray the materials in the material storage bin through compressed air pulses.

[0083] Furthermore, in some embodiments of the present invention, enclosures are provided on both sides of the belt conveyor, and a flow limiting gate is provided at the outlet of the belt conveyor.

[0084] Furthermore, in some embodiments of the present invention, the adjustment module 20 is also used to obtain the maximum production capacity of the optical sorter; obtain the target discharge flow rate of the belt conveyor according to the maximum production capacity of the optical sorter; and adjust the height of the flow limiting gate according to the target discharge flow rate of the belt conveyor.

[0085] Furthermore, in some embodiments of the present invention, the intelligent sorting equipment also includes a vibrating feeder, and the control module 10 is further used to control the vibrating feeder to evenly spread the material laterally after the flow of the belt conveyor is limited.

[0086] Furthermore, in some embodiments of the present invention, the control module 10 is also used to, after controlling the pneumatic arch breaking device to perform the arch breaking action, if the material discharge flow rate of the material storage bin has not changed, control the pneumatic arch breaking device to continue to perform the arch breaking action until the material discharge flow rate of the material storage bin changes.

[0087] It should be understood that the specific implementation of the feeding control device of the intelligent sorting equipment in the embodiment of the present invention corresponds one to one with the specific implementation of the feeding control method of the intelligent sorting equipment in the aforementioned embodiment of the present invention, and will not be repeated here to reduce redundancy.

[0088] In summary, according to the feeding control device of the intelligent sorting equipment of the embodiment of the present invention, when the intelligent sorting equipment is started, the control module controls the pneumatic valve to open to the half-open door position, and then obtains the material discharge flow of the material storage bin through the adjustment module, and adjusts the opening of the pneumatic valve according to the material discharge flow of the material storage bin, and controls the pneumatic arch breaking device to perform the arch breaking action when the arch breaking module detects that the material discharge flow of the material storage bin has not changed. Thus, by adjusting the opening of the pneumatic valve at the outlet of the material storage bin, the material discharge flow of the material storage bin is accurately controlled, and pneumatic arch breaking is used to solve the problem of poor discharge, so as to keep the material flow relatively stable and give full play to the production capacity of the optical sorting machine, thereby improving the sorting efficiency and output of plastic bottles.

[0089] Figure 7 is a block diagram of an intelligent sorting device according to an embodiment of the present invention.

[0090] Specifically, in some embodiments of the present invention, Figure 7 As shown, the intelligent sorting equipment 2000 includes the feeding control device 1000 of the intelligent sorting equipment of the above-mentioned embodiment of the present invention.

[0091] It should be understood that the specific implementation of the intelligent sorting equipment of the embodiment of the present invention can refer to the specific implementation of the feeding control method of the intelligent sorting equipment of the embodiment of the present invention mentioned above, and will not be repeated here to reduce redundancy.
