Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] like Figure 1-Figure 5 As shown, a single-end chamfered parts sorting device is disclosed, comprising: A swing sorting part 3, the input end of which is connected to a twisting guide tube 2 for turning the parts to be sorted from a horizontal state to a vertical state, and the output end is provided with a receiving guide groove 6; Detection parts 4 for detecting the chamfered side of parts are provided on both sides of the swing sorting part, and a driving mechanism 5 is provided at the bottom of the swing sorting part. The driving mechanism drives the swing sorting part to rotate to one side according to the chamfering signal of the parts detected by the detection part, and outputs the chamfered side horizontally upward to the receiving guide groove 6.

[0020] It is worth noting that, when in use, the sorting device is arranged as a whole at an angle, with the feed trough 1 at the input end being at a high position and the receiving guide trough 6 at the output end being at a low position.

[0021] In the specific implementation of this embodiment, Figure 1 As shown, the twisting conduit 2 is a rectangular conduit twisted 90 degrees and tilted. The high-end input end of the twisting conduit 2 is horizontal and docked with the bottom outlet of the feed trough 1; the low-end discharge end of the twisting conduit 2 is upright and docked with the swing sorting part.

[0022] Since the feed trough 1 is an open guide trough and is tilted, the tilted single-sided chamfered part 7 moves naturally to the lower right from the feed trough 1, slides through the twisting conduit 2 and twists 90 degrees in the direction, and the single-sided chamfered part changes from a tilted horizontal state to an upright state. Specifically, the single-sided chamfered part 7 is placed horizontally in the feed trough 1, and slides into the twisting conduit 2. Since the twisting conduit 2 is twisted 90 degrees, the single-sided chamfered part 7 entering horizontally is changed to an upright state, and then enters the swing sorting part 3.

[0023] In the specific implementation of this embodiment, Figure 2 and Figure 3 As shown, the swing sorting part 3 is located at the discharge end of the twisting conduit 2 (see Figure 1 , Figure 2), which is composed of a sorting tube body 31, an arc-shaped baffle plate 32, a hinged ear plate 33, a hinge support 34, a first rotating shaft 35, etc. The sorting tube body 31 is a rectangular short tube, which is arranged vertically, and the axis of the tube mouth is inclined. The high-end inlet (left end) is connected to the low-end discharge end of the torsion guide tube 2. The bottom discharge port (right end) is slidably opposed to the semicircular baffle plate 61 on the receiving guide groove 6. Arc-shaped baffle plates 32 are respectively arranged on both sides of the high-end inlet end of the sorting tube body 31. The arc-shaped baffle plates are centered on the first rotating shaft 35 and are used to block the low-end discharge port of the torsion guide tube 2 when the sorting tube body 31 rotates 90 degrees to both sides around the rotating shaft 35, so as to prevent the parts to be sorted in the torsion guide tube 2 from descending at this time. A hinged ear plate 33 is fixedly arranged below the sorting tube body 31, and the sorting tube body 31 is hingedly connected to the hinge support 34 through the hinged ear plate 33 and the first rotating shaft 35. The inclination direction of the first rotating shaft 35 is consistent with the axial direction of the nozzle of the sorting tube body. The hinge support 34 is fixed to the frame (the frame is not shown in the figure). The detection part 4 is respectively provided on the two outer sides of the sorting tube body 31. The detection part 4 is located at a lower middle position at an equal distance from the two nozzles, close to the bottom plate (see the attached figure). Figure 2 , Figure 3 , Figure 4 ). In the specific implementation of this embodiment, Figure 4 As shown in FIG. 1 , the detection part 4 is fixed to the two outer sides of the sorting tube body 31 through the side plates 41, and a herringbone swing plate 42 is hingedly provided at the lower end of the small side plate 41 through a swing plate hinge support 412 and a second rotating shaft 43. The swing plate inner section 421 is movably arranged in the notches 311 on both sides of the middle of the bottom of the sorting tube body 31 (see attached Figure 2 , 3 ), the outer section 422 of the swing plate is in a roughly horizontal position. The torsion spring 44 sleeved on the second rotating shaft 43 gently presses down the outer section 422 of the swing plate, so that the inner section 421 of the swing plate tends to move upward. The detection probe 45 is vertically arranged above the outer section 422 of the swing plate, and the detection probe 45 is fixed by the probe fixing plate 411. During detection, the working principle of the detection part 4 is as follows: after the single-sided chamfered part enters the sorting tube body, the right-angled edge of the side of the part that is not chamfered presses down the inner section 421 of the swing plate on that side, and the outer section 422 of the swing plate on that side (overcoming the slight elastic force of the torsion spring) moves upward and contacts the detection probe 45 (see attached Figure 3 The left side of the part has no influence on the position of the inner section 421 of the swing plate on that side, and the outer section 422 of the swing plate on that side continues to keep a distance from the detection probe 45 (see attached figure). Figure 3On the right side), the detection probe 45 on the right side has no signal. The driving mechanism 5 is located below the swing sorting part 3. The driving motor 51 is fixed to the frame, and a gear 1 52 is fixedly provided on the motor shaft of the driving motor 51, and a gear 2 53 is fixedly provided on the rotating shaft 35. The rotating shaft 35 is fixedly connected to the hinged ear plate 33. The driving motor 51 drives the swing sorting part 3 to rotate 90 degrees to both sides through gear 1 52, gear 2 53 and the first rotating shaft 35. The receiving guide groove 6 is located at the rear end of the sorting device and is tilted. The upper end feed port is wide, and the lower end discharge port 64 is narrow. A semicircular baffle 61 is fixedly provided in the middle of the upper end feed port. The semicircular baffle 61 slides relative to the lower end port of the sorting tube body 31 to prevent the parts in the sorting tube body 31 from moving downward before tilting. The semicircular baffle 61 divides the upper inlet of the receiving guide groove 6 into two parts. The rear inlet 62 corresponds to the lower end of the sorting tube body 31 after tilting backwards by 90 degrees; the front inlet 63 corresponds to the lower end of the sorting tube body 31 after tilting forwards by 90 degrees. Sorting process: The single-side chamfered part 7 slides naturally to the lower right from the feed trough 1, and continues to slide into the sorting tube body 31 after adjusting the direction by the twisting guide tube 2. The side without chamfer 71 presses the inner section 421 of the swing plate deeper, so that the outer section 422 of the swing plate tilts up higher and contacts the probe 45. Due to the limitation of chamfer 7, the side with chamfer 7 hits the middle position of the inner section 421 of the swing plate. The height of the outer section 422 of the swing plate tilting up is relatively low and cannot touch the probe. Then the probe on the side with chamfer 7 will not send a signal. When the detection probe 45 sends a signal, the drive motor 51 drives the swing sorting part 3 to tilt 90 degrees to the side where the signal is sent through the gear set and the rotating shaft 35. The parts in the sorting tube body automatically slide out of the receiving guide groove 6 below, so that the chamfered end faces upward. The swing sorting part 3 is reset. And so on. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
