Description

Technical Field

[0001] The utility model relates to the technical field of logistics sorting, in particular to a mixed real-time sorting device for items of multiple specifications. Background Art

[0002] Traditional sorting mechanisms, such as impact sorting mechanisms and sponge belt launchers, have the following problems: impact sorting mechanisms have low sorting efficiency, at around 10,000 items per hour (an operation frequency of approximately 2.7 items per second), and items struck out are prone to skewing, rolling, and misalignment. While sponge belt launchers offer high sorting efficiency, reaching around 30,000 items per hour, they are primarily suitable for items of uniform size. They are less stable and adaptable when mixed with items of varying sizes.

[0003] As sorting requirements evolve, the need to sort items of varying sizes and specifications increases. This necessitates the development of a new sorting mechanism and method that is both efficient and adaptable to the diverse size and specifications of these items. Note: The term "multi-size items" refers to a group of items with varying dimensions (length, width, and height). Of course, the differences in length, width, and height should be minimal, ensuring that these items can be properly placed within the sorting mechanism.

[0004] Chinese patent CN202311149859.4 discloses a mixed real-time sorting mechanism and method for multi-specification items. The mechanism has high sorting efficiency and is suitable for sorting items of multiple sizes. However, the technical solution is difficult to meet the requirements of automated sorting and needs further refinement and improvement. Summary of the Invention

[0005] The purpose of the utility model is to provide a real-time sorting device for mixed items of multiple specifications, which can realize automatic sorting, has high sorting efficiency, is suitable for items of multiple sizes, has a simple control process and is reliable in operation.

[0006] The technical solution of the present utility model is as follows: a device for real-time sorting of mixed items of multiple specifications, comprising an inclined replenishment channel, a transition belt mechanism connected to the bottom of the replenishment channel, a sorting bin connected to the bottom of the transition belt mechanism, the sorting bin comprising an inclined conveyor belt, an exit parker provided at the bottom of the conveyor belt, and a movable pressure plate mechanism provided on the conveyor belt; an end sorting photoelectric sensor, a replenishment photoelectric sensor and a full bin photoelectric sensor are provided on the conveyor belt, the end sorting photoelectric sensor is provided at the exit parker position, the full bin photoelectric sensor is provided on the upper part of the conveyor belt, and the replenishment photoelectric sensor is provided on the middle part of the conveyor belt; a smoke pressing sorting photoelectric sensor is provided on the pressure plate mechanism of the sorting bin.

[0007] A flow strip is provided on the replenishment channel.

[0008] The transition belt mechanism is provided with a belt for transmission, and a driving wheel of the belt is connected to the output shaft of the motor through a chain.

[0009] An upper limit gear is provided above the conveyor belt.

[0010] A left limiting bar and a right limiting bar are provided on the left and right sides of the conveyor belt, and an article sliding channel is reserved between the left limiting bar and the right limiting bar.

[0011] The transition belt mechanism is arranged to be inclined at 5-15 degrees to the horizontal plane.

[0012] The beneficial effects of the present invention are as follows: the present invention adopts a replenishment channel for storing items and delivering the items to the transition belt. Compared with the belt replenishment channel, the present invention eliminates the need for components such as a power mechanism and a photoelectric sensor, and also eliminates the need for a complex control system. Since the items can be moved downward by gravity in the flow strip and replenished in real time, the present invention is low-cost, easy to install, and has a reliable structure. The transition belt is used to connect the sorting bin and the replenishment channel. A shorter transition belt can block the items in the replenishment channel and deliver them to the replenishment channel. The replenishment channel can automatically complete the automatic control of replenishment and sorting through photoelectric sensing, reducing the chance of errors and improving sorting efficiency.

[0016] The present invention will be further described below with reference to the embodiments, but they are not intended to limit the present invention.

[0017] Example 1. A device for real-time sorting of mixed items of multiple specifications comprises an inclined replenishment channel 1, with a transition belt mechanism 2 connected to the bottom of the replenishment channel 1, and a sorting bin 3 connected to the bottom of the transition belt mechanism 2. The sorting bin 3 comprises an inclined conveyor belt 301, an exit stop 302 disposed at the bottom of the conveyor belt 301, and a movable pressure plate mechanism 303 disposed on the conveyor belt 301. The conveyor belt 301 is equipped with an end sorting photoelectric sensor 304, a replenishment photoelectric sensor 305, and a full bin photoelectric sensor 306. The end sorting photoelectric sensor 304 is located at the exit stop 302, the full bin photoelectric sensor 306 is located above the conveyor belt 301, and the replenishment photoelectric sensor 305 is located in the middle of the conveyor belt 301. The device detects the presence of items at various positions on the conveyor belt 301. The pressure plate mechanism 303 of the sorting bin 3 is equipped with a smoke suppression photoelectric sensor 307 to detect whether there are items beneath the pressure plate mechanism 303.

[0018] The replenishment channel 1 is provided with a smooth strip 101 to reduce friction.

[0019] The transition belt mechanism 2 is provided with a transmission belt 201 , a driving wheel 202 of the belt 201 is connected to the output shaft of a motor 204 via a chain 203 , and the transmission action of the transition belt mechanism 2 is controlled by the motor 204 .

[0020] An upper limit stop 310 is provided above the conveyor belt 301 to prevent objects from jumping out when falling.

[0021] The conveyor belt 301 is provided with a left limit bar 308 and a right limit bar 309. A sliding channel for items is left between the left limit bar 308 and the right limit bar 309 to limit the position of the items and prevent them from deviating when falling, so that the items can slide to the bottom of the pressure plate mechanism 303 when leaving the warehouse.

[0022] The transition belt mechanism 2 is arranged to be inclined at 5-15 degrees with respect to the horizontal plane, so as to ensure that most items slide smoothly without jumping.

[0023] The method of using the mixed real-time sorting device for multi-specification items is to store items through the replenishment channel 1 and transfer the items to the transition belt mechanism 2; the transition belt mechanism 2 transfers the items to the sorting bin 3, and the sorting bin 3 performs the sorting work.

[0024] The sorting work of sorting bin 3 is as follows:

[0025] Step 1. Before the sorting operation is performed, first determine whether the end sorting photoelectric sensor 304 and the replenishment photoelectric sensor 305 have signals at the same time;

[0026] Step 2. When the sorting conditions in step 1 are met, the pressing plate mechanism 303 moves to the position where the cigarettes need to be pressed. Once in position, the cigarette pressing and sorting photoelectric sensor 307 detects whether there are any items at this position. If there are no cigarettes, the feedback system reports an error. If there are cigarettes, the pressing plate mechanism 303 activates to press the items, and the exit stopper 302 at the bottom of the conveyor belt 301 opens to release the items at the front of the conveyor belt 301. The exit stopper 302 closes after there is no signal from the end sorting photoelectric sensor 304. The pressing plate mechanism 303 then retracts, and the items in the conveyor belt 301 slide down and are replaced at the exit stopper 302.

[0027] Step 3. After the delay, check whether the end sorting photoelectric sensor 304 and the replenishment photoelectric sensor 305 have signals at the same time; if the end sorting photoelectric sensor 304 has a signal and the replenishment photoelectric sensor 305 has no signal, it means that the items in the conveyor belt 301 are not full and need to be replenished. The transition belt mechanism 2 will be activated to transport the items to the conveyor belt 301 for replenishment. The next sorting will not start until the replenishment photoelectric sensor 305 has a signal; if the full warehouse photoelectric sensor 306 has a signal, it is considered that the replenishment is complete, and the transition belt mechanism 2 will stop replenishing.

[0028] Example 2. A device for real-time sorting of mixed items of multiple specifications comprises an inclined replenishment channel 1, with a transition belt mechanism 2 connected to the bottom of the replenishment channel 1. The bottom of the transition belt mechanism 2 is connected to a sorting bin 3. The sorting bin 3 comprises an inclined conveyor belt 301, with an exit stop 302 located at the bottom of the conveyor belt 301, and a movable pressure plate mechanism 303 located on the conveyor belt 301. The conveyor belt 301 is equipped with an end sorting photoelectric sensor 304, a replenishment photoelectric sensor 305, and a full bin photoelectric sensor 306. The end sorting photoelectric sensor 304 is located at the exit stop 302, the full bin photoelectric sensor 306 is located above the conveyor belt 301, and the replenishment photoelectric sensor 305 is located in the middle of the conveyor belt 301. A smoke suppression photoelectric sensor 307 is installed on the pressure plate mechanism 303 of the sorting bin 3 to detect whether there are items below the pressure plate mechanism 303.

[0029] The transition belt mechanism 2 adopts an existing belt transmission mechanism.

[0030] The method of using the device for real-time sorting of mixed items of multiple specifications is the same as that of Example 1.
