[0093] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0094] Example 1

[0095] refer to Figure 1-7 This application provides an automatic sorting and counting device for packaged products, used to sort several packaged products into a single packaged product, including: an automatic feeding system 1, a sorting and conveying system 2, a storage system 3, and a counter 5. The automatic feeding system 1 is used to convey the packaged products to the sorting and conveying system 2, and the storage system 3 stores the sorted packaged products. The automatic feeding system 1 can be a conveyor belt with partitions that continuously runs to bring the packaged products to a vibrating screen, and the structure and power of the vibrating screen guide the packaged products into the sorting and conveying system 2.

[0096] The sorting and conveying system 2 includes m feeding channels 21, each feeding channel 21 including a tilting de-weighing mechanism 211, a cascaded accelerating de-weighing mechanism 212, and a dropping mechanism; where m is a natural number greater than or equal to 2. The dropping mechanism is used to smoothly drop a single packaged product into the storage system 3; the tilting de-weighing mechanism 211 is used to remove excess material that overlaps (e.g., two overlapping packages); the cascaded accelerating de-weighing mechanism 212 includes n-stage accelerating channels for progressively accelerating the conveying of packages; where n is a natural number greater than or equal to 2.

[0097] In this embodiment, the sorting and conveying system 2 includes six feeding channels 21. Each feeding channel 21 includes an inclined de-weighing mechanism 211, a cascaded accelerating de-weighing mechanism 212, and a dropping mechanism. The inclined de-weighing mechanism 211 includes an inclined de-weighing channel 2111, and the cascaded accelerating de-weighing mechanism 212 includes a first-stage accelerating channel 2121, a second-stage accelerating channel 2122, and a third-stage accelerating channel 2123. The inclined de-weighing channel 2111 is connected to the first-stage accelerating channel 2121. The inclined de-weighing channel 2111 includes an inclined conveyor belt. The first-stage accelerating channel 2121 includes a first-stage cascaded conveyor belt, the second-stage accelerating channel 2122 includes a second-stage cascaded conveyor belt, and the third-stage accelerating channel 2123 includes a third-stage cascaded conveyor belt. Each cascaded conveyor belt is parallel to the horizontal plane (as used herein, "horizontal plane" refers to a plane parallel to the ground), and the inclined conveyor belt forms an angle with the horizontal plane. included angle The angle range is 30-80°, preferably 45-75°. Additionally, the inclined conveyor belt includes an inclined conveying section and a bottom baffle, which together form an inclined de-weighting channel 2111. The width of the bottom baffle is only sufficient to accommodate the conveying of a single packaged product. That is, after two packages with more than 80% overlap (one packaged product pressing on top of the other, with an overlap exceeding 80%) pass through the inclined de-weighting mechanism 211, the packaged product on top will fall out of the inclined de-weighting channel 2111. Preferably, the inclined conveyor belt is equipped with a vacuum adsorption component, which ensures that even under conditions of inclination angle, belt vibration, and product interaction, products adhering to the belt can be firmly adsorbed and conveyed to the cascaded accelerating de-weighting mechanism.

[0098] The inclined de-weighting channel 2111, the first-stage acceleration channel 2121, the second-stage acceleration channel 2122, and the third-stage acceleration channel 2123 are driven by a motor. The conveying speed of the inclined de-weighting channel is v0. The first-stage acceleration channel 2121 is connected to the inclined de-weighting channel 2111, and the second-stage acceleration channel 2122 is connected to the first-stage acceleration channel and the third-stage acceleration channel. The conveying speed of the first-stage acceleration channel is v1, the conveying speed of the second-stage acceleration channel is v2, and the conveying speed of the third-stage acceleration channel is v3. Preferably, v3 / v2 = 1.2~3, v2 / v1 = 1.2~3, and v1 / v0 = 1.2~3. More preferably, v1 / v0 = 1.2, v2 / v1 = 1.4, and v3 / v2 = 1.6. In this embodiment, the inclined acceleration channel 2111 and the first-stage acceleration channel 2121 are driven by a first motor, and the second-stage acceleration channel 2122 and the third-stage acceleration channel 2123 are driven by a second motor. Preferably, the first motor includes a gearbox, and different transmission speeds of the inclined de-weighting channel 2111 and the first-stage acceleration channel 2121 are achieved through different gear ratio combinations within the gearbox. The second motor includes a gearbox, and different transmission speeds of the second-stage acceleration channel 2122 and the third-stage acceleration channel 2123 are achieved through different gear ratio combinations within the gearbox.

[0099] The inventors designed different speeds for each channel primarily to ensure that partially overlapping packaged products separate due to the speed difference when passing through any two channels with different speeds. In other embodiments, the conveying speed of the inclined de-weighting channel 2111 can be the same as that of the first-stage acceleration channel, the conveying speed of the second-stage acceleration channel can be greater than that of the first-stage acceleration channel, and the conveying speed of the third-stage acceleration channel can be greater than that of the second-stage acceleration channel. Preferably, an acceleration component is also provided at the end of the third-stage acceleration channel to facilitate the rapid entry of packaged products into the unloading mechanism.

[0100] To count the packaged products falling into the feeding mechanism, this device also includes a counter 5, which is located at the end of the third-stage acceleration channel 2123. When the packaged products fall into the feeding mechanism from the third-stage acceleration channel, the counter 5 completes the counting. The counter 5 can be a counting sensor, etc.

[0101] To improve the sorting accuracy of the automatic sorting and counting device for packaged products of the present invention, a first probe and a purging deweighting mechanism are provided at the end of the second-stage acceleration channel 2122 of the cascaded acceleration deweighting mechanism 212. The first probe is used to detect the quantity and / or status of the packaged products conveyed to the purging deweighting section, and the purging deweighting mechanism is used to purge overlapping packaged products that were not removed in the cascaded acceleration deweighting mechanism. The purging deweighting mechanism includes a gas source, a gas flow channel with a gas inlet and a gas outlet, and an airflow switch valve provided on the gas flow channel for opening or closing the gas flow channel.

[0102] The purging and de-duplication mechanism performs purging in the following two states: First, it is used to remove overlapping packages that were not removed in the cascaded accelerated de-duplication mechanism. Second, counter 5 has an on state and an off state. When the counter has not finished counting, that is, when the counter is on, the purging and de-duplication mechanism will blow away all packages in the purging and de-duplication section. This prevents the next package from being conveyed to the end of the cascaded accelerated de-duplication channel before the counter has finished counting the previous package, thus affecting the accuracy of the counter's counting.

[0103] Specifically, firstly, when the first probe detects that the strip products being transported to the end of the second-stage acceleration channel 2122 (i.e., the purging and de-weighting section) still overlap (i.e., when two strip products in succession on the second-stage acceleration channel overlap), the purging and de-weighting mechanism is activated, and the airflow switch valve on the airflow channel is opened to blow away the strip products following on the second-stage acceleration channel 2122, so that the strip products entering the third-stage acceleration channel are single and there is no overlap between two consecutive strip products being transported; secondly, when the strip products fall from the third-stage acceleration channel 2123 into the unloading mechanism, and the counter 5 has not completed the counting work, the purging and de-weighting mechanism will blow away all the strip products being transported to the end of the second-stage acceleration channel 2122 (i.e., the purging and de-weighting section) to avoid inaccurate counting.

[0104] Preferably, in order to facilitate the blowing of overlapping packaged products off the second cascade conveyor belt, a first baffle is installed on the side of the first cascade conveyor belt, and a second baffle is installed on the side of the second cascade conveyor belt, the height of the second baffle being less than the height of the first baffle; preferably, a cover is provided above the second cascade conveyor belt for airflow guidance to prevent packaged products from flying around randomly.

[0105] In this embodiment, the device further includes a first recycling channel and / or a second recycling channel 4. The first recycling channel is located below the tilting deweighting mechanism and is used to collect the strip-packaged products that fall from the tilting deweighting channel and return them to the automatic feeding system 1 for re-sorting. The second recycling channel is located below the second-stage acceleration channel of the cascaded acceleration deweighting mechanism and is used to collect the strip-packaged products blown off by the blowing deweighting mechanism and return them to the automatic feeding system for re-sorting.

[0106] In this embodiment, the device further includes a controller 6, which acts as the processor of the device, used to receive and send control commands to various mechanisms and complete information transmission between them. The controller 6 can receive information from the first probe and the counter 5; that is, the first probe and the counter (e.g., a laser probe and a counting sensor) transmit signals to the controller, which determines whether the purging and de-weighing mechanism needs to be activated and executes the purging function. In this embodiment, the controller also includes a control panel, used to monitor various mechanisms, display various information (operating status, production statistics, troubleshooting guidance, etc.), set various parameters (product specification parameters, counting requirement parameters, factory parameters, etc.), and display various alarms (controller communication errors, motor and sensor fault alarms, etc.).

[0107] All documents mentioned in this application are considered to be incorporated in their entirety into the disclosure of this application so that they can serve as a basis for modifications if necessary. Furthermore, it should be understood that after reading the foregoing disclosure of this application, those skilled in the art can make various alterations or modifications to this application, and these equivalent forms also fall within the scope of protection claimed in this application.
