In this embodiment, the number of the first outlet 24 and the second outlet is one, and the number of the inlets is two.

The sorting mechanism comprises an access pipe 3, a first sorting sub mechanism, a second sorting sub mechanism, a controller, a plurality of conveying belts and a collector.

The access pipe 3 is located in the first space 210, one end of the access pipe 3 is fixed on the first partition plate 21 and covers the central hole, and the other end of the access pipe 3 receives the packaging bags 100 to be classified and stored through the top of the inner shell 2. The window 10 at the top of the cabinet 1 is communicated with the access pipe 3, so that the packing bag 100 falls into the second space 220 through the access pipe 3. The access pipe 3 may be fixed to the first partition 21 by welding.

The first sorting sub-mechanism is located in the second space 220 and comprises a circular truncated cone 4, a tiling assembly, a pushing assembly, a plurality of code scanning instruments and a prompting device.

The circular truncated cone 4 is located in the second space 220, the lower table is fixed on the second partition 22, and the upper table is located below the access pipe 3 to receive the packaging bag 100 from the access pipe 3. In this embodiment, the slope of the side surface of the circular truncated cone 4 may be designed according to the size of the packaging bag 100, as long as the packaging bag 100 can smoothly slide down on the side surface of the circular truncated cone 4.

The tiling assembly includes at least one baffle 42 and at least one driver corresponding to the at least one baffle 42. The driver drives the corresponding baffle 42 to rotate around the circular truncated cone 4 along the side surface of the circular truncated cone 4, and the baffle 42 flatly lays the packaging bag 100 on the side surface of the circular truncated cone 4 in the rotating process. The shutter 42 may be a plate body having an arc shape as a whole, and the driver may be a stepping motor. In this embodiment, the baffle 42 is spaced apart from the side of the circular truncated cone 4 by a certain height, which is the thickness of the packing bag 100, so as to prevent the packing bag 100 from being stacked and not achieving the flat-laying effect.

The pushing assembly includes a plurality of pushing plates 43 corresponding to the plurality of second drop holes 221 and a plurality of pushers corresponding to the plurality of pushing plates 43. The pusher drives the push plate 43 to push the packing bag 100 on the side of the circular truncated cone 4 along the side of the circular truncated cone 4.

Each second drop hole 221 corresponds to two code scanners: one code scanner is arranged on the automatic closing door at the second falling hole 221, and the other code scanner is arranged on the inner wall of the inner shell 2 in the space two 220 and corresponds to the position of the second falling hole 221. The code scanning instrument is used for scanning the code of the packaging bag 100 pushed by the push plate 43 on the automatic closing door at the second falling hole 221 so as to acquire the product information code on the corresponding packaging bag 100. A trigger switch for controlling the power-on of the code scanner 7 can be arranged on the inner wall of the inner shell 2 near the corresponding second drop hole 221. When the push plate 43 moves to the corresponding second drop hole 221, the push plate touches the trigger switch, so as to trigger the code scanner, and the code scanner is powered on to start code scanning.

The second sorting sub-mechanism is located in the third space 230 and comprises an impeller and a rotator. The impeller is installed on the center of the third partition plate 23 through a rotating shaft, the central shaft is perpendicular to the third partition plate 23, and the rotator drives the impeller to rotate by driving the rotating shaft to rotate. A receiving area 52 is formed between two adjacent blades 51 of the impeller, and each receiving area 52 is communicated with a second space (220) through a second drop hole 221; the third drop hole 231 is located in one of the receiving areas 52.

And each outlet I24 is pivoted with the corresponding inlet and each outlet II is pivoted with the corresponding inlet through a conveying belt. If the first outlet 24 and the second partition 22 are located on the same horizontal plane and are communicated with the second space 220, the first inlet is communicated with the first space 210, each first outlet 24 is pivoted with the corresponding first inlet through a first conveying belt 61, if the second outlet and the third partition 23 are located on the same horizontal plane and are communicated with the third space 230, the second inlet is communicated with the first space 210, each second outlet is pivoted with the corresponding second inlet through a second conveying belt 62, and the second conveying belt 62 extends into the corresponding accommodating area 52 through the corresponding second outlet.

The controller defines the second drop hole 221 corresponding to the third drop hole 231 as an overdue drop hole by encoding the second drop holes 221, and defines the other second drop holes 221 as drop holes within the quality guarantee period step by step according to the descending grade between the expected maximum number of days and zero. The predicted maximum number of days may be B days, defining that the interval of 0 days-A days is the first mouth drop within the quality guarantee period, A +1 days-B-1 days is the second mouth drop within the quality guarantee period, A, B is a positive integer and B is greater than A. In this example, B is 60 days and A is 30 days. The number of the second dropping holes 221 is 3, and the second dropping holes correspond to overdue dropping openings, first dropping openings within the quality guarantee period and second dropping openings within the quality guarantee period respectively; the number of the receiving areas 52 is 3 corresponding to the second dropping hole 221.

The controller calculates the difference between the current date and the expiration date T in the product information code, judges whether the difference between the number of days is greater than zero, controls the corresponding pusher to drive the push plate 43 to push the corresponding packaging bag 100 to the overdue falling opening falling position when the difference between the number of days is not greater than zero, and controls to open the automatic closing door under the corresponding packaging bag 100, so that the corresponding packaging bag 100 falls through the overdue falling opening, falls into the containing area 52 where the falling hole III 231 is located, and enters the space IV 240 through the falling hole III 231.

And the controller judges whether the number of days difference is greater than zero, and judges whether the number of days is within the number of days of the quality guarantee period of the corresponding grade step by step according to the number of days of the quality guarantee period defined step by the descending grade, if so, the corresponding pusher is controlled to drive the push plate 43 to push the corresponding packaging bag 100 to the corresponding drop hole II 221, and the automatic closing door under the corresponding packaging bag 100 is controlled to be opened, so that the corresponding packaging bag 100 falls into the corresponding containing area 52.

Otherwise, the controller continues to judge until the controller judges that the difference value of the days is larger than the maximum preset value, the pusher is controlled to drive the push plate 43 to push the corresponding packaging bag 100 to one of the first outlets 24, the overlapped conveying belt 6 at the first outlet 24 is controlled to be started, and the corresponding packaging bag 100 is conveyed to the first space 210 through the corresponding conveying belt 6.

And when the controller judges that the difference value of the days is larger than the expected maximum days, the controller can control the corresponding pusher to drive the push plate 43 to push the corresponding packaging bag 100 to one of the outlets I24, control the overlapped conveying belt I61 at the outlet I24 to be started, and transmit the corresponding packaging bag 100 to the space I210 through the corresponding conveying belt I61 so as to be sorted again after n days.

The collector is installed in the first through space 210 and comprises a collecting plate 7 and a rotator. One end of the collecting plate 7 is rotatably installed at the center of the first partition plate 21, the other end of the collecting plate 7 is suspended on the first partition plate 21, the collecting device drives the collecting plate 7 to rotate by taking one end of the center of the first partition plate 21 as a rotating point, and therefore packaging bags in the first space 210 are rotated by the suspended end of the collecting plate 7 and fall into the second space 220 from the first falling hole 211.

After m days after the bagged snack food storage cabinet finishes sorting, the controller controls to start the second conveyor 62 overlapped at each second outlet, and the corresponding packaging bag 100 is conveyed into the first space 210 through the corresponding second conveyor 62 so as to be sorted again after n days.

In other embodiments, the expected maximum number of days is B days, defining the interval of 0 days-a days as the first mouth in shelf life, a +1 days-B-1 days as the second mouth in shelf life, more than B days as the third mouth in shelf life, A, B is a positive integer and B is greater than a. The number of the second dropping holes 221 is 4, and the second dropping holes correspond to overdue dropping holes, first dropping holes in quality guarantee periods, second dropping holes in quality guarantee periods and third dropping holes in quality guarantee periods respectively; the number of the receiving areas 52 is 4 corresponding to the second falling hole 221. Thus, the packaging bags 100 which are longer than B days are not conveyed into the first space 210 by the first conveying belt 61, but are directly conveyed into the third space 230, and finally conveyed into the second space 220 by the second conveying belt 62 for re-sorting.

The prompting device is used for alarming and prompting. The prompting device in this embodiment may be a voice broadcast device, and in other embodiments, the prompting device may also be a buzzer, or other devices as long as the prompting of people by the prompting device is not affected. The prompting of the prompting device has certain periodicity. When the package 100 is pushed into the corresponding receiving area 52, the controller may drive the prompting device to alarm to a corresponding degree. The staff can set the alarm period according to actual needs. The alarm device can enable people to know whether food is overdue in time and process food to be overdue or overdue food.

In summary, referring to fig. 10, the method for sorting the shelf life of the controller includes the following steps.

And calculating the difference value of the number of days between the current date and the expiration date in the product information code, and judging whether the difference value of the number of days is greater than zero.

When the difference of the number of days is not greater than zero, the corresponding pusher is controlled to drive the push plate 43 to push the corresponding packaging bag 100 to the overdue drop opening, and the automatic closing door below the corresponding packaging bag 100 is controlled to be opened, so that the corresponding packaging bag 100 drops through the overdue drop opening, falls into the containing area 52 where the drop hole three 231 is located, and enters the space four 240 through the drop hole three 231.

And when the difference value of the days is larger than zero, judging whether the difference value of the days is between 0 day and A day, if so, controlling the corresponding pusher to drive the push plate 43 to push the corresponding packaging bag 100 to the corresponding second drop hole 221, and controlling the automatic closing door under the corresponding packaging bag 100 to be opened, so that the corresponding packaging bag 100 falls in the containing area 52 corresponding to the 0 day and the A day.

And when the difference value of the days is larger than zero and the difference value of the days is beyond 0 day-A day, continuously judging whether the difference value of the days is between A +1 day-B-1 day, if so, controlling the corresponding pusher to drive the push plate 43 to push the corresponding packaging bag 100 to the corresponding drop hole II 221, and controlling to open the automatic closing door below the corresponding packaging bag 100 so that the corresponding packaging bag 100 falls into the containing area 52 corresponding to the A +1 day-B-1 day.

When the difference of the days is larger than the expected maximum days (i.e., B days), the corresponding pusher is controlled to drive the pushing plate 43 to push the corresponding packaging bag 100 to the first outlet 24, the overlapped conveying belt 61 at the first outlet 24 is controlled to be started, and the corresponding packaging bag 100 is conveyed into the first space 210 through the corresponding conveying belt 61 to be sorted again after n days.
