Referring to fig. 1 to 9, in order to improve the smoothness of picking and placing the picking frames, the present application provides a sorting assembly 10 and a sorting device using the sorting assembly 10. A plurality of sorting assemblies 10 are arranged on the sorting device, and each sorting assembly 10 can be used for picking and placing the sorting frame 500 to cooperatively carry out the material handling work. The innovative concepts of the sorting assembly 10 and sorting apparatus described above and the manner of realisation thereof will be described below by way of example with reference to the accompanying drawings.

Fig. 1 to 8 illustrate a sorting assembly 10 according to an embodiment of the present application, which is mainly used for picking and placing a picking frame 500 to complete the sorting of the warehoused goods. Typically, the pick frames 500 are stored on a shelf (not shown) so that the sorter assembly 10 is used to pick the pick frames 500 from the shelf or place the pick frames 500 into the shelf. The sorting assembly 10 comprises a circulating conveying mechanism 100, a driving motor 200 and an electromagnetic adsorption mechanism 300, wherein the driving motor 200 is used for driving the circulating conveying mechanism 100 to work, and the electromagnetic adsorption mechanism 300 is arranged on the electromagnetic adsorption mechanism 300 and moves along with the circulating conveying mechanism 100. The circulating conveying mechanism 100 comprises a conveying support 130 for carrying the picking frames 500, a driving motor 200 is in transmission connection with the conveying support 130 and drives the conveying support 130 to reciprocate, and an electromagnetic adsorption mechanism 300 is connected with the conveying support 130 and is configured for adsorbing the picking frames 500.

In the illustrated embodiment, the endless transfer mechanism 100 includes a support frame 110, a transfer wheel 120 rotatably disposed on the support frame 110, and the transfer support 130 engaged with the transfer wheel 120. The driving motor 200 is in transmission connection with the conveying wheel 120, the electromagnetic adsorption mechanism 300 comprises a support 310 connected with the conveying support 130 and an electromagnet 320 arranged on the support 310, and the electromagnet 320 is used for adsorbing the picking frame 500.

The sorting assembly 10 is used with a magnetically attracted sorting frame 500. For example, the outer surface of the picking frame 500 may be provided with a magnetic conductive plate 510 for the magnet 320 to attract, and the magnetic conductive plate 510 may be made of a material that is easily magnetically attracted, such as an iron plate or a ferrous alloy plate. If the pick frame 500 itself is made of or includes a magnetically permeable material so that the pick frame 500 may be electromagnetically attracted, the magnetically permeable plates 510 may not be additionally disposed on the pick frame 500. The conveying support 130 is formed with a plane for supporting the picking frame 500, and the driving motor 200 drives the conveying support 130 to reciprocate circularly through the conveying wheel 120, so as to drive the electromagnetic adsorption mechanism 300 connected to the conveying support 130 to move back and forth. When the picking frame 500 needs to be picked from the shelf, the circular conveying mechanism 100 drives the electromagnetic adsorption mechanism 300 to extend to be close to the picking frame 500, the electromagnetic adsorption mechanism 300 adsorbs the picking frame 500 through the electromagnet 320, and then the picking frame 500 is conveyed to the conveying support member 130 under the driving of the circular conveying mechanism 100. Referring to fig. 5 to 6, when the material needs to be unloaded to the designated shelf or the designated position of the shelf, the circular conveying mechanism 100 drives the electromagnetic absorption mechanism 300 to extend again to push the picking frame 500 to the designated shelf, and the electromagnetic absorption mechanism 300 is powered off to separate the electromagnet 320 from the picking frame 500. Wherein the endless transfer mechanism 100 takes the load and torque from the material during the transfer of the pick frame 500 (i.e., from the rack into the sorting device 20, and from the sorting device 20 into the rack) and assists in the transfer of the pick frame 500. During handling, the electromagnetic attraction mechanism 300 needs to pull or push the pick frame 500 a small distance only during the initial stage when the pick frame 500 is from the rack to the transfer support 130 and the final stage when the pick frame 500 is entering the rack from the transfer support 130. When the picking frame 500 is located on the conveying support 130 or mostly on the conveying support 130, the picking frame 500 is mainly conveyed by the conveying support 130, and the electromagnetic adsorption mechanism 300 only plays a role in preventing the picking frame 500 from swaying laterally.

In the above technical solution of the present application, the driving motor 200 drives the conveying support 130 to move back and forth through the conveying wheel 120, so as to drive the electromagnetic adsorption mechanism 300 connected to the conveying support 130 to move back and forth to pick and place the picking frame 500. The conveying support 130 is provided with a plane for placing the picking frame 500, and the circular conveying mechanism 100 bears the load and the torque brought by the materials in the conveying process of the picking frame 500 and assists the materials to transfer, so that the materials are conveyed not only by the electromagnetic adsorption mechanism 300, and the stability of the conveying process is improved.

In the embodiment shown in the drawings, the endless conveying mechanism 100 is a chain conveying mechanism, the conveying wheel 120 is a chain wheel, the conveying support 130 is a chain plate, and the driving motor 200 drives the chain wheel to rotate, so as to drive the chain plate and the electromagnetic absorption mechanism 300 on the chain plate to reciprocate. In other embodiments, the circulating transmission mechanism 100 may also be a belt transmission mechanism, the transmission wheel 120 is a synchronous pulley, the transmission support 130 is a synchronous belt, and the driving motor 200 drives the synchronous pulley to rotate, so as to drive the synchronous belt and the electromagnetic absorption mechanism 300 on the synchronous belt to reciprocate. Further, since the picking frame 500 is supported and conveyed on the upper side of the circulating conveyor mechanism 100, the electromagnetic adsorption mechanism 300 is preferably disposed on the upper side of the circulating conveyor mechanism 100, and the driving motor 200 drives the circulating conveyor mechanism 100 by forward and reverse rotation so that the electromagnetic adsorption mechanism 300 performs the circularly reciprocating linear motion only on the upper side of the circulating conveyor mechanism 100.

In the illustrated embodiment, the electromagnetic attraction mechanism 300 further includes a first position sensor 330 disposed on the support 310, the first position sensor 330 being configured to feed back whether the picking frame 500 is attracted thereto and to detect the position status of the picking frame 500 and the electromagnet 320. The first position sensor 330 is disposed proximate the electromagnet 320 to enable real-time reflection of the position of the pick frame 500 and the electromagnet 320 to ensure successful grasping of the pick frame 500.

In the illustrated embodiment, the sorter assembly 10 further includes a second position sensor 400, the second position sensor 400 is disposed at a side of the support 110 of the endless transfer mechanism 100, and the support 310 is provided with a sensing portion 311, the sensing portion 311 extending to a side of the support 110 to be able to be detected by the second position sensor 400 when passing the second position sensor 400. The second position sensor 400 is used for feeding back the real-time position of the electromagnetic adsorption mechanism 300, when the electromagnetic adsorption mechanism 300 moves along with the conveying support 130, the induction part 311 on the support 310 moves along with the electromagnetic adsorption mechanism, and the induction part 311 is detected by the second position sensor 400 when passing through the second position sensor 400, so that a feedback effect is generated on the position fed back to the electromagnetic adsorption mechanism 300. In the embodiment shown in the drawings, the number of the second position sensors 400 is 3, and the second position sensors are respectively disposed at the front end, the rear end and the middle position of one side of the bracket 110, so that the electromagnetic absorption mechanism 300 can generate feedback signals when being located at the extension limit position, the retraction limit position and the middle position. In other embodiments, the number of the second position sensors 400 may also be 2, and the second position sensors are respectively disposed at the front end and the rear end of one side of the bracket 110, that is, the extended limit position and the retracted limit position of the electromagnetic adsorption mechanism 300. In other embodiments, the number of second position sensors 400 may be other suitable numbers.

In the illustrated embodiment, the driving motor 200 and the second position sensor 400 are respectively located at opposite sides of the endless conveyor 100, a guide plate 312 is provided on one end of the holder 310 near the driving motor 200, the guide plate 312 extends in the conveying direction of the endless conveyor 100, and both the electric wire of the driving motor 200 and the conductive wire of the first position sensor 330 are engaged with the guide plate 312. In this embodiment, since the electric wires of the driving motor 200 and the wires of the first position sensor 330 are also moved when the electromagnetic adsorption mechanism 300 moves along with the conveying support 130, the electric wires of the driving motor 200 and the wires of the first position sensor 330 are both engaged with the guide plate 312 to prevent the electric wires from being wound or damaged. Specifically, a drag chain may be provided on the guide panel 312, and the electric wire of the driving motor 200 and the wire of the first position sensor 330 are installed in the drag chain.
