The article pasted with the bar code passes through the roller line 6 and falls on the trolley 3 through the feeding port 5, the trolley 3 carries the article and passes through the detection device 8, and the detection device 8 identifies the bar code of the article and uploads the bar code to the processor.

As shown in fig. 2, a flap folding mechanism 12, a first sensor 13 and a speed sensor 14 are arranged in front of a blanking area formed by the blanking port 10. The speed sensor 14 is a correlation sensor, because of the working characteristics of the correlation sensor and the characteristics of the frame type of the trolley 3, the installation position of the speed sensor 14 is located at the position shielded by the trolley 3, so that the gap between the trolleys 3 can be accurately detected, the error report caused by the characteristics of the frame when the trolley 3 passes through is avoided, the height of the speed sensor is as high as the top cross rod of the vertical frame of the trolley, and thus, when the correlation sensor is shielded by the cross rod, the passing trolley is judged to be the same trolley, when the current trolley passes through, the next trolley comes, because of the gap between the two trolleys, the correlation sensor can detect the gap, and then the next trolley can be judged to come again. In practical applications, the number of the speed sensors 14 can be set by itself, and six pairs are provided in the present embodiment. The speed sensors 14 can detect the gap between the trolleys 3, and the distance between every two adjacent pairs of speed sensors 14 is 90mm, so that the running speed of the trolleys 3 can be obtained by measuring the time when the gap of the trolleys 3 passes through the two adjacent pairs of speed sensors 14, namely 90 mm/time. Five intervals are formed between the six pairs of speed sensors, so that five speeds can be obtained, and the average value of the five speeds is taken, so that the relatively accurate running speed of the transmission line can be obtained. According to the running speed of the transmission line, when the feeding sensor 7 detects an article, the controller can adjust the roller line motor, so that the running speed of the roller line is adjusted, and the article can be accurately descended to the trolley 3 from the discharging opening.

As shown in fig. 17, the control system of the ceiling-based sorter includes a processor, a controller, and a memory, wherein the controller is in bidirectional communication with the processor and the processor is in communication with the memory. The detection device 8 is connected with the processor, and the detection device shown in fig. 17 is a vision mechanism which is at least one camera, and the vision mechanism is connected with the processor through a vision processing module. The visual mechanism acquires the bar code shape on the article and transmits the bar code shape to the visual processing module, and the visual processing module carries out digital processing on the bar code information and uploads the bar code information to the processor; the touch screen and the bar code input device are connected with the processor, and the bar code input device is generally a code scanning gun. The bar code of the article is transmitted to the processor through the bar code input device or the information (such as material opening, article bar code, type and the like) of the article is manually transmitted to the processor through the touch screen, and the information of the bar code transmitted by the detection processing module, the bar code transmitted by the bar code input device or the information of the bar code of the article input by the touch screen and the like is transmitted to the memory for storage by the processor. The processor is connected with the controller through a TCP/IP communication protocol. The controller is connected with the transmission line driving motor, the roller line driving motor and the blanking executing mechanism and is used for controlling the transmission line driving motor, the roller line driving motor and the blanking executing mechanism; meanwhile, the controller is also connected with the first sensor 13, the speed sensor 14 and the feeding sensor, and the first sensor 13, the speed sensor 14 and the feeding sensor send signals to the controller.

Before the transmission line works, the bar codes of the articles are recorded and stored in the memory through the touch screen or the bar code recording device, and the processor matches the bar codes with the feed opening. In order to ensure the accuracy of the classification, the controller needs to acquire the bar code of the article dropped onto the cart 3 from the loading port 5 and the cart number of the cart 3 carrying the article. The bar code of the article falling onto the cart 3 is collected by the detection device 8 and transferred to the processor, and the cart number of the cart 3 carrying the article needs to be calculated additionally. A certain pair of speed sensors 14 is assigned to count the cars, one of the cars 3 is assigned a number one on which a mark, such as a radio frequency card, is provided, which the sensor 13 can identify. The first sensor 13 is mounted vertically above or below a certain speed sensor 14 designated to count the cars, and in this embodiment, the first sensor 13 is mounted above the first speed sensor 14. When the first sensor 13 detects the first car, the counter of the controller counts to 1, and the designated speed sensor 14 counts by 1 every time it detects a gap (gap between two adjacent cars), i.e. every time it passes by one car 3, and since the total number of cars is fixed, the counter counts cyclically from 1 after a full circle (i.e. the number of cars counted is the total number of cars), in this way, the number of cars passing through the feeding port 5 is determined. Since the distance M1 from the sensor number one 13 to the feed opening 5 is fixed (in the opposite direction to the advancing direction of the cart), the length L of each cart is also fixed, so that the number of the cart passing through the feed opening 5 can be determined. For example, if the counter counts exactly 4, i.e. the car number passing through the first sensor 13 is exactly 4, then the car number passing through the feeding port 5 is: 4+ [ M1/L ] (4 plus an integer quotient of M1 and L). When the trolley 3 carries the articles to reach the corresponding feed opening 10, the controller controls the feed execution mechanism 11 to open the turning plate at the bottom of the trolley 3 to discharge the articles, then the turning plate folding mechanism 12 folds the turning plate at the bottom of the trolley 3, and the trolley 3 continues to run along the annular guide rail 2. Since the running speed of the conveyor line (i.e. the running speed of the trolley) is calculated, the distance from the feeding opening to the blanking opening or the fault discharging opening is known, and the time T1 when the trolley positioned at the feeding opening reaches the blanking opening or the fault discharging opening can be obtained by dividing the distance by the speed, wherein T1 is M2/V, wherein in the advancing direction of the trolley, M2 represents the distance from the feeding opening to the corresponding blanking opening, and V is the running speed of the trolley.

When the article is unloaded, the article passes through the photoelectric sensor 16 and falls into a box (not shown in the figure) below the feed opening 10, the photoelectric sensor 16 counts the fallen article, and when the count reaches a set numerical value, the box is judged to be full, and the box can be replaced manually.

As shown in fig. 18, the control flow of the hanging sorting machine is as follows:

the first step is as follows: and the articles to be sorted reach the feeding port. Prior to this, the bar code of the item has been entered into the memory and the feed opening is dispensed by the processor.

The second step is that: after the feeding sensor detects the articles, the controller adjusts the roller line driving motor, so that the running speed of the roller line is adjusted, and the articles are ensured to accurately fall onto the trolley from the discharging opening.

The third step: and dropping the article onto the trolley from the feeding port, and recording the number of the trolley, wherein the method introduced in the foregoing is adopted for obtaining the number of the trolley.

The fourth step: the trolley passes through the vision mechanism, the vision mechanism acquires the bar codes of the articles on the trolley and sends the bar codes to the processor, and the processor searches in the memory according to the bar codes and judges whether the bar codes have corresponding feed openings. If yes, executing the fifth step; if the eighth step is not performed.

The fifth step: and for the article with the corresponding feed opening, the processor acquires the feed opening and the trolley number corresponding to the article and sends the feed opening and the trolley number to the controller.

And a sixth step: the trolley reaches the corresponding feed opening, the controller controls the action of a feed executing mechanism of the feed opening, the turning plate of the trolley is opened, and the articles fall into a box (not shown in the box) which is arranged on the bracket 15 and is arranged below the feed opening.

The seventh step: and finishing sorting.

Eighth step: the processor acquires the trolley number corresponding to the article and sends the trolley number to the controller.

The ninth step: when the trolley reaches a fault discharge opening, the controller controls the action of the discharging executing mechanism of the discharge opening, the turning plate of the trolley is opened, and the articles fall down.

The tenth step: manually processing unidentifiable articles, placing the articles on a roller line after the processing is finished, and re-sorting the articles; the work of the first step is repeated.
