Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to a mixed real-time sorting system and method for multi-specification items. Background Art

[0002] Traditional sorting mechanisms, such as strike sorting mechanisms and sponge belt launching mechanisms, have the following problems: For example, the strike sorting mechanism has a low sorting efficiency of about 10,000 pieces / hour (the action frequency is close to 2.7 pieces / second), and the items struck out are prone to deflection, rolling, and misalignment. Although the sponge belt launching mechanism has a high sorting efficiency of about 30,000 pieces / hour, it is mainly suitable for items with uniform size specifications. If items of different specifications are mixed together, the sorting is not stable enough and the adaptability is poor.

[0003] With the development of sorting requirements, there are more and more items of different sizes and specifications to be sorted. It is necessary to develop a new sorting mechanism and method that is not only efficient but also applicable to the sorting of items of different sizes and specifications. Note: The meaning of the term "multi-specification items" refers to a batch of items with different sizes and specifications (length, width and height). Of course, the length, width and height of this batch of items cannot differ too much, and the basic requirement is that they can be reasonably placed in the sorting mechanism.

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

[0005] The object of the present invention is to provide a mixed real-time sorting system and method for multi-specification items, which can realize automatic sorting, has high sorting efficiency, is applicable to items of multiple sizes, has a simple control process, and is reliable in operation.

[0006] The technical solution of the present invention is a mixed real-time sorting system for items of multiple specifications, including an inclined replenishment channel, a transition belt mechanism is connected to the bottom of the replenishment channel, the bottom of the transition belt mechanism is connected to the sorting bin, the sorting bin includes an inclined conveyor belt, an exit parker is provided at the bottom of the conveyor belt, and a movable pressure plate mechanism is provided on the conveyor belt.

[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] The conveyor belt is provided with an end sorting photoelectric sensor, a replenishment photoelectric sensor and a full warehouse photoelectric sensor. The end sorting photoelectric sensor is arranged at the exit parking position, the full warehouse photoelectric sensor is arranged at the upper part of the conveyor belt, and the replenishment photoelectric sensor is arranged in the middle part of the conveyor belt.

[0010] A smoke pressing and sorting photoelectric sensor is provided on the pressing plate mechanism of the sorting bin.

[0011] The conveyor belt is provided with a left limit stop bar, a right limit stop bar and an upper limit stop bar, and an article sliding channel is reserved between the left limit stop bar and the right limit stop bar.

[0012] The method used by the mixed real-time sorting system for multi-specification items is to store items through the replenishment channel and transfer the items to the transition belt mechanism; the transition belt mechanism transfers the items to the sorting bin, and the sorting bin realizes the sorting work.

[0013] The sorting work of the sorting warehouse is as follows: Step 1. Before the sorting action is executed, first determine whether the end sorting photoelectric sensor and the replenishment photoelectric sensor have signals at the same time; Step 2. When the sorting conditions in step 1 are met, the pressing plate mechanism moves to the position where the cigarettes need to be pressed. After moving to the position, the pressing and sorting photoelectric sensor will detect whether there are any items at this position; if there is no smoke, the system will be fed back with an error; if there is smoke, the pressing plate mechanism will press the items, and the exit stopper at the bottom of the conveyor belt will open to release the items at the front of the conveyor belt, until there is no signal from the end sorting photoelectric sensor, and then the exit stopper will close; then the pressing plate mechanism will retract, and the items in the conveyor belt will slide down to the exit stopper; Step 3. After the delay, check whether the end sorting photoelectric sensor and the replenishment photoelectric sensor have signals at the same time; if the end sorting photoelectric sensor has a signal and the replenishment photoelectric sensor has no signal, it means that the conveyor belt is not full and needs to be replenished. The transition belt mechanism will move the items to the conveyor belt for replenishment until the replenishment photoelectric sensor has a signal and then start the next sorting; if the full warehouse photoelectric sensor has a signal, it can be considered that the replenishment is completed, and the transition belt mechanism stops replenishing.

[0014] Beneficial effects of the present invention: The present invention adopts a replenishment channel to store items and replenish items to the transition belt. Compared with the belt replenishment channel, it eliminates the power mechanism, photoelectric sensor and other components, and also eliminates the complex control system. Since the items can be moved down by gravity in the flow strip and replenished in real time, it is low-cost, easy to install and reliable in 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 transport the items to the replenishment channel. The replenishment channel can automatically complete the automatic control of replenishment and sorting through photoelectric sensing, which reduces the probability of errors and improves sorting efficiency.
