Referring to fig. 1, a schematic diagram of an embodiment of a hook screening apparatus according to the present invention is shown. The screening apparatus of the present invention includes a hopper 10, and,

the material taking assembly 20 is arranged above the material storage box 10, and the material taking assembly 20 is arranged above the material storage box 10; the take-out assembly 20 picks up material from the bin 10.

Screening subassembly 30, screening subassembly 30 set up in get material subassembly 20 below, get material subassembly 20 and pick up the material and send to screening subassembly 30 top afterwards, send the material to in the screening subassembly 30. Screening subassembly 30 is provided with screening groove 31, screening groove 31 bottom is filtering seam 32, filtering seam 32 both sides are inclined plane 33, and the material drops in screening groove 31, because both sides are inclined plane 33, therefore the material drops to filtering seam 32's position, and the couple that the gesture meets the requirements leaks from filtering seam 32, and unsatisfactory couple is blockked in screening groove 31. In order to send the unsatisfactory hooks away from the screening groove 31, the first material receiving box 35 is arranged below one end of the screening groove 31, the material pushing plate 34 is arranged in the other end of the screening groove 31, the material pushing plate 34 is matched with the inclined surface 33, the material pushing plate 34 pushes out, all materials in the screening groove 31 are pushed out of the screening groove 31, and the materials fall into the first material receiving box 35 below. In order to simplify the structure of the screening device of the present invention and increase the continuous operation capability of the device, in this embodiment, the storage box 10 and the first material receiving box 35 are disposed in a superposed manner, that is, the storage box 10 and the first material receiving box 35 are the same box, and the screening assembly 30 is disposed between the material taking assembly 20 and the storage box 10. The materials which are not required in the screening are directly returned to the material storage box 10, so that the steps of material circulation in the first material receiving box 35 and the material storage box 10 are reduced, and the flow is simplified.

First conveying assembly 40, first conveying assembly 40 feed end set up in filter seam 32 below, first conveying assembly 40 discharge end is provided with first detection sensor, first conveying assembly 40 discharge end below is provided with second and receives workbin 36. After the couple that the gesture meets the requirements spills from filtering seam 32 in the screening, drop on first transmission assembly 40, first transmission assembly 40 sends this couple out, when first detection sensor detects the couple that does not meet operation requirements, first transmission assembly 40 continues the conveying, the couple drops to second from first transmission assembly discharge end and receives in the workbin 36, then screen again, when first detection sensor detects the couple that meets operation requirements, first transmission assembly 40 stops the conveying, be convenient for next station to take.

Further, the material taking assembly 20 comprises a first horizontal cylinder 21, a first vertical cylinder 22 and a first electromagnet 23, the first vertical cylinder 22 is connected with the first horizontal cylinder 21, and the first electromagnet 23 is installed at the end of a push rod of the first vertical cylinder 22. First horizontal cylinder 21 in this embodiment sets up in storage case 10 and screening subassembly 30 top through the support, and first vertical cylinder 22 is promoted by first horizontal cylinder 21 and is removed along the horizontal direction, makes first vertical cylinder 22 remove to directly over storage case 10, and the first vertical cylinder 22 of back stretches out downwards, drives first electro-magnet 23 and inserts in the storage case 10, and first electro-magnet 23 adsorbs and resets after the couple. The first electromagnet 23 adsorbs 5-10 hooks each time, and since the hooks are piled up when falling into the screening slot 31 and only the lower hooks can pass through the filtering slits 32, it is not desirable to place too many hooks in the screening slot 31 each time. Adopt the adsorbed mode of electro-magnet in this embodiment, get material quantity on the one hand and suitable and occupation space is little, and on the other hand is with low costs.

Referring to fig. 2, in order to ensure that the hooks passing through the filtering slot 32 are in a proper posture, i.e., the hanging ring and the fixing piece are in an unfolded state, and only one hook can leak onto the first conveying assembly 40 at each position, the width of the filtering slot 32 is greater than the thickness of the hooks and less than the thickness of the superposition of the hanging ring and the fixing piece. Thus, only the hooks with the angle of 180 degrees between the hanging ring and the fixing sheet can pass through the filtering slot 32, and the hooks with other angles between the hanging ring and the fixing sheet are blocked in the screening slot 31. Further, the distance between the upper surface of the first conveying assembly 40 and the filtering slot 32 is greater than the width of the hook and less than the length of the hook, so that only the laterally arranged hook can pass through the filtering slot 32, and the vertical hook still has a part in the screening slot 31 and is then pushed out by the material pushing plate 34. The hooks falling on the first conveying assembly 40 are arranged along the length direction of the filtering slot 32, and the consistency of the hook direction is ensured. In order to push the material pushing plate 34 to move so as to push out the remaining materials in the screening slot 31, the material pushing plate 34 is connected with a material pushing cylinder, and the material pushing cylinder is arranged along the length direction of the filtering slot 32.

The first conveying assembly 40 includes a first conveyor belt 41 and a first driving motor 42, and the first driving motor 42 is connected to the first conveyor belt 41 by a driving wheel. Because the hook falls to the conveyer belt and is in a side lying mode, the conveyer belt adopted in the embodiment can ensure the hook to be supported, and the hook is prevented from falling from the gap of the conveyer assembly. Furthermore, in order to ensure that the first conveying assembly 40 can bear as many hooks as possible and ensure that the hooks fall in the middle of the width direction of the conveying belt, the first conveying assembly 40 is arranged along the length direction of the filtering slot 32. The position of the hook can be determined by determining the position of the hook in the conveying direction of the conveyor belt, and the hook can be picked up accurately in the next step.

Referring to fig. 3, since the direction of the hooks on the first conveyor belt 41 is the same as the length direction of the filtering slot 32, if the direction of the hooks required during installation is perpendicular to the length direction of the filtering slot 32, the screening apparatus further includes a transferring assembly 50 for diverting the hooks to output. The transfer assembly 50 comprises a steering assembly and a second conveying assembly 51, the transfer assembly 50 is arranged above the first conveying assembly 40 and the second conveying assembly 51, and the transfer assembly 50 picks up the materials on the first conveying device and places the materials on the second conveying assembly 51 after being steered.
