As shown in fig. 1(a), the automatic sorting mechanism according to an embodiment of the present invention includes a toggle mechanism 910, a main channel 901, two or more sub-channels 902, and sorting storage devices 903 in the same number as the sub-channels.

The main channel 901 is respectively communicated with each secondary channel 902 and forms a corresponding branch 901-1 at the joint, each secondary channel 902 corresponds to one sorting storage device 903, the toggle mechanism 910 can toggle the workpiece 930 so as to enable the workpiece 930 to advance to each branch 901-1 along the main channel 901, and enable the workpiece 930 to reach the corresponding secondary channel 902 through any branch 901-1 and then reach the corresponding sorting storage device 903 through the secondary channel 902. If a sorting command (sorting category obtained by manual recognition or automatic recognition) is issued, the corresponding workpiece 930 will be pushed into the corresponding branch and slide into the corresponding sorting storage device 903 via the branch, and if no sorting command is issued, the corresponding workpiece 930 will be pushed forward by the toggle mechanism 910 and move to the next branch along the main channel 901.

In order to save space and cost, in one embodiment, the sub-channel 902 and the corresponding sorting storage 903 may be combined into one part or one of them may be omitted, and such modifications or changes are still within the scope of the present invention.

In order to save space and cost, in one embodiment, several of the sorting storage devices 903 or all of the sorting storage devices 903 may be combined into one part, and space division may be implemented by means of grooves, spacers, or sufficient spacing gaps, and these modifications or changes still fall within the protection scope of the present invention.

In one embodiment, the secondary channel 902 is an inclined open slot with an adjustable slot width. In another embodiment, the secondary channel 902 is an open chute with a fixed slot width that is larger than the maximum width of the workpiece 930, thereby simplifying the structure and eliminating the slot width adjustment mechanism of the secondary channel 902. The maximum width of the workpiece 930 is the maximum width of the workpiece with the largest width among the workpieces 930 of respective sizes expected to be applicable when the sorting mechanism is designed.

In one embodiment, the secondary channels 902 are respectively located at two sides of the primary channel 901, for example, the secondary channels 902 are alternately distributed at two sides of the primary channel 901, that is, a first secondary channel 902 is distributed at the left side of the primary channel 901, a second secondary channel 902 is distributed at the right side of the primary channel 901, a third secondary channel 902 is distributed at the left side of the primary channel 901, and so on.

In another embodiment, the secondary channels 902 are all located on one side of the primary channel 901. At the moment, the automatic sorting mechanism is compact in structure, beneficial to saving the number of the movement mechanisms, capable of reducing space interference, convenient to design, install and adjust and convenient for workers to operate.

The communication may be a cross connection as shown in fig. 1(a), or may be a non-cross connection, i.e., a certain distance is kept between the main channel 901 and the sub-channel 902, but the workpiece 930 is considered to be communicated as long as the workpiece 930 can slide from the main channel 901 into the corresponding sorting storage device 903 through the sub-channel 902.

In one embodiment, the automatic sorting mechanism of an embodiment of the present invention further includes a sorting base 920 for fixedly mounting the main components to be fixedly mounted as described above and below. In one embodiment, the automated sorting mechanism is integrally and fixedly mounted to the sorting base 920.

In one embodiment, the toggle mechanism 910 includes a main pushing unit 911 and the same number of ejecting units 913 as the number of the secondary channels 902; the ejection unit 913 includes a pusher 913-2, the pusher 913-2 can hold the workpiece 930 to push the workpiece 930 to move or advance along the main path 901, and when the workpiece 930 reaches the designated branch 901-1, the pusher 913-2 can eject the workpiece 930 from the main path 901 into the sub-path 902 and to the corresponding sorting storage 903 through the sub-path 902; the main pushing unit 911 provides pushing force for the workpiece 930 to sequentially pass through the branch ports 901-1 along the main passage 901.

In one embodiment, the toggle mechanism 910 further comprises a toggle base 914 for fixedly mounting the major components of the toggle mechanism 910. The toggle base 914 is fixedly installed on the sorting base 920.

To further improve the degree of automation and flexibility, and to improve the efficiency of automatic sorting and the quality of the sorted goods, in one embodiment, the toggle mechanism 910 further includes a toggle unit 912. The card-moving unit 912 may drive all the ejecting units 913 to reciprocate in a direction perpendicular to the moving line of the workpiece 930 in the main passage 901.

As shown in fig. 2(a) and 2(b), in one embodiment, when the card-poking unit 912 is away from the main channel 901, the poking heads 913-2 of all the ejection units 913 are away from the workpiece 930, i.e. the poking heads 913-2 no longer seize the workpiece 930, and thus cannot push the workpiece 930 to move along the main channel 901; when the engaging unit 912 approaches or abuts the main channel 901, the engaging heads 913-2 of all the ejecting units 913 move toward the workpiece 930 and engage the workpiece 930 (when there is a corresponding workpiece 930 in the main channel 901 at a corresponding position of the ejecting units 913), so as to push the workpiece 930 to move linearly along the main channel 901.

In one embodiment, as shown in FIG. 1(b), the pusher 913-2 includes a card pushing edge 913-2-1 and a push-out edge 913-2-2, respectively.

The clamping edge 913-2-1 may clamp and abut against one side of the workpiece 930 to push the workpiece 930 to move linearly along the main channel 901 toward the other side of the workpiece 930.

The ejection edge 913-2-2 may abut against one side of the workpiece 930 and push the workpiece 930 to move linearly along the side of the workpiece 930 toward the other side of the workpiece 930 along the sub-channel 902 or slide into the sorting storage device 903 corresponding to the sub-channel 902.

In one embodiment, as shown in fig. 1(b), the side of workpiece 930 that abuts against raised edge 913-2-2 is perpendicular to the side that abuts against card edge 913-2-1, i.e., raised edge 913-2-2 is perpendicular to card edge 913-2-1. At the moment, the system is simple and compact in structure and convenient to design and engineer.

In other embodiments, the ejecting edge 913-2-2 of the shifting block 913-2 and the clamping edge 913-2-1 form an angle different from 90 degrees, which is the same as the angle between the secondary channels of the primary channel.

In one embodiment, the main pushing unit 911, the card dialing unit 912 and each ejecting unit 913 each include a corresponding linear driving mechanism, and each linear driving mechanism corresponds to the main pushing driving mechanism 911-1, the card dialing driving mechanism 912-1 and the ejecting driving mechanism 913-1, respectively.

Each linear driving mechanism can be realized by adopting a hydraulic cylinder or a pneumatic cylinder which outputs linear motion, and can also be realized by adopting a motor and a linear transmission mechanism such as a ball screw, a gear rack, a worm gear, a belt transmission mechanism, a chain transmission mechanism and the like, and can also be directly driven by adopting a linear motor. The motor can be a standard servo motor product with a speed reducer, and can also be a conventional servo motor product without a speed reducer, such as a torque motor and the like. Each linear driving mechanism also relates to a linear guide rail, a driving control device, a position feedback device or an anti-collision device and the like for linear guiding, the specific installation, manufacture and use modes of the linear driving mechanisms refer to the prior art, and the linear driving mechanisms can be specifically selected or combined according to the specific workpiece category and characteristics and are conventional prior art.

In one embodiment, each of the main pushing unit 911, the card dialing unit 912 and each of the ejecting units 913 includes a corresponding guiding component for guiding and supporting the linear movement of the moving portion relative to the fixed portion, and each guiding component corresponds to the main pushing guiding component 911-3, the card dialing guiding component 912-3 and the ejecting guiding component 913-3, respectively.

Each guide assembly can adopt a universal standard product, namely a linear guide rail, namely a combination of a guide rail and a slide block, the installation mode is installed according to a conventional mode, namely the slide block is fixed with the mobile station, the guide rail is fixed with the fixed seat, a structure with two guide rails arranged in parallel is adopted, the guide assemblies are conventional prior art, and the description is omitted.

In one embodiment, because each ejection unit 913 is only acting on a single workpiece, the force is relatively small, and to save cost, the corresponding ejection guide assembly 913-3 can be eliminated, directly using the ejection drive mechanism 913-1 as the guide support structure of the linear cylinder itself.

In one embodiment, the main push unit 911 has a long acting length, needs to bear a large weight, and simultaneously takes space saving into consideration, so that the structure is compact, the main push guide assembly 911-3 adopts a single-groove sliding groove type structure, that is, a linear sliding groove is arranged on the toggle base 914, one or more than one sliding block is fixedly arranged on the main push movable worktable 911-2, and the linear guide function and the support function are realized through the matching of the sliding block and the sliding groove.
