[0017] For example, see Figures 1 to 3 As shown, a hub conveying and sorting device includes a front and rear conveying frame 10, wherein the front and rear conveying frame 10 includes two upper transverse beams 11 on the left and right, and two ends of a plurality of electric rollers 13 (which can be directly purchased on the market and are not described in detail here) are installed on the two upper transverse beams 11, and the electric rollers 13 can directly rotate; the bottom surfaces of the two upper transverse beams 11 are fixed on the supporting frame below;

[0018] A groove 12 extending downward is formed in the middle of the top surface of the upper transverse beam 11 on the right side of the front and rear conveying frame 10, and the bottom surface of the groove 12 is lower than the top of the electric roller 13 in the front and rear conveying frame 10;

[0019] A transverse conveying frame 20 is fixed on the right side wall of the upper transverse beam 11 on the right side of the front and rear conveying frames 10. The transverse conveying frame 20 includes two corresponding front and rear transverse beams. The bottom surface of the transverse beam is fixed on the lower support frame below, and multiple electric rollers 13 are installed on the two transverse beams.

[0020] The left end feed port of the transverse conveying frame 20 corresponds to the groove 12, and the top of the electric roller 13 in the transverse conveying frame 20 is level with or lower than the top of the electric roller 13 of the front and rear conveying frames 10;

[0021] An infrared transmitter 1 and an infrared receiver 2 for detecting the length of time the wheel hub passes are fixed to the top surfaces of the left and right upper transverse beams 11 of the front and rear conveying frames 10 at the rear of the groove 12, respectively. The infrared transmitter 1 irradiates infrared rays to the receiving end of the infrared receiver 2;

[0022] A horizontal support frame 30 is fixed on the left side wall of the upper horizontal beam 11 on the left side of the front and rear conveying frames 10 corresponding to the groove 12, a connecting plate 31 is fixed on the left top surface of the horizontal support frame 30, a pushing cylinder 32 is fixed on the left side wall of the connecting plate 31, the end of the push rod of the pushing cylinder 32 extends out of the right side wall of the connecting plate 31 and is fixed with a pushing plate 33, and the pushing plate 33 faces the top of the groove 12.

[0023] Furthermore, elastic limit blocks 34 are fixed to the front and rear of the right side wall of the push plate 33. The inner side walls of the two elastic limit blocks 34 are inclined wall surfaces, and the left ends of the two wall surfaces are close to each other and the right ends are far away from each other.

[0024] Furthermore, a plurality of transverse guide rods 35 are fixed on the left side wall of the push plate 33 , and the transverse guide rods 35 are inserted into guide through holes formed on the connecting plate 31 .

[0025] Furthermore, a horizontal connecting plate 14 is fixed to the lower part of the front and rear conveying frames 10 opposite to the middle part of the pushing plate 33, a lower fixing frame 15 is fixed to the top surface of the horizontal connecting plate 14, a limiting cylinder 16 is fixed to the bottom surface of the top plate of the lower fixing frame 15, the top end of the push rod of the limiting cylinder 16 extends out of the top surface of the top plate of the lower fixing frame 15 and is fixed with a lifting plate 17, vertical limiting rods 18 are fixed to the left and right parts of the top surface of the lifting plate 17, and the upper parts of the two vertical limiting rods 18 are inserted into the through grooves between the corresponding two electric rollers 13 of the front and rear conveying frames 10.

[0026] Furthermore, a plurality of vertical guide rods 171 are fixed to the bottom surface of the lifting plate 17 , and the vertical guide rods 171 are inserted into vertical guide through holes formed on the top plate of the lower fixing frame 15 .

[0027] When the embodiment is in use, the wheel hub is placed on the front and rear conveying racks 10 and conveyed forward. When the wheel hub passes between the infrared transmitter 1 and the infrared receiver 2, the infrared rays are blocked from irradiating the infrared receiver 2. Different wheel hubs have different times of passing between the infrared transmitter 1 and the infrared receiver 2.

[0028] At present, the casting and spinning fast assembly line has a line speed of 9.0 m / min. The diameter of a 20-inch wheel is 508.0 mm. The speed of the fast assembly line is converted to seconds, 150.0 mm / s. Without considering the friction coefficient between the wheel product and the roller, the time required for a 20-inch wheel product to flow through the photoelectric switch detection point is:

[0029] T = hub diameter (length) / speed (150.0 mm / s) = 508.0 mm / 150.0 (mm / s) = 3.387 s

[0030] Through calculation, the theoretical time required for a 20-inch wheel to pass through the photoelectric switch is 3.387s.

[0031] The diameter of the 14-inch product is 355.6mm.

[0032] T = hub diameter (length) / speed (150.0 mm / s) = 355.6 mm / 150.0 (mm / s) = 2.37 s

[0033] Similarly, by calculation, the time required for a 14-inch wheel to pass through the photoelectric switch is 2.37s, and the size of the wheel passed can be obtained by the time difference;

[0034] For example, if you need to sort out a 20-inch wheel hub, when the time between the wheel hub passing through the infrared transmitter 1 and the infrared receiver 2 is 3.387s, it can generally be set to 3.3 seconds to 3.5 seconds. When the infrared receiver 2 can sense the infrared rays after 3.3 seconds to 3.5 seconds, it means that the wheel hub passing by is 20 inches. The signal sent by the existing infrared receiver 2 is a pulse signal. Therefore, in the control host, that is, in the PLC controller, enabling M0.0 (10Hz) of the system clock MB0 is equivalent to sending a pulse every 100ms. If 2.37s is calculated based on a 14-inch wheel hub, the measured result is: the number of pulses = 2.37*1000 / 100 = 23.7 (the number of pulses). According to 3.3 seconds to 3.5 seconds, it is 33 to 35 pulses, that is, when the infrared receiver 2 sends 33 to 35 pulses, it does not sense the infrared rays, which means that the wheel hub passing by is 20 inches.

[0035] At this time, the control host controls the operation of the control valve of the hydraulic system, so that the push rod of the limit cylinder 16 pushes, so that the tops of the two vertical limit rods 18 extend out of the tops of the through grooves between the corresponding two electric rollers 13. At this time, the wheel hub is blocked by the two vertical limit rods 18 when it continues to be transported forward. At the same time, the control host controls the operation of the control valve of the hydraulic system controlling the push cylinder 32, so that the push rod of the push cylinder 32 pushes, and when the push rod of the push cylinder 32 is pushed for 1 to 2 seconds, the control host controls the limit cylinder The control valve 16 operates, causing the push rod of the limit cylinder 16 to retract, causing the tops of the two vertical limit rods 18 to retract. At this time, as the push plate 33 is pushed to the right, the wheel hub will continue to be transported forward without being blocked until the push plate 33 approaches the wheel hub. At this time, the wheel hub will be just between the two elastic limit blocks 34 and push the wheel hub to the right, and push it into the horizontal conveying frame 20 from the groove 12. Through the operation of the electric roller 13 of the horizontal conveying frame 20, it will continue to be transported to the right, with good conveying effect and accurate sorting.

[0036] Then, all parts return to their positions and continue to wait for the subsequent delivery of the wheel hub.

[0037] Among them, all electrical equipment in this embodiment are electrically connected to the control host through electrical connecting lines, and the hydraulic pump, electric control valve, etc. in the hydraulic system connected to the pushing cylinder 32 and the limiting cylinder 16 are electrically connected to the control host through electrical connecting lines to achieve control. Its hydraulic system and other components are all conventional structures and will not be described in detail here.

[0038] Furthermore, a horizontal fixing plate 50 is fixed at the front upper transverse beam of the transverse conveying frame 20 and the upper transverse beam 11 on the right side of the front and rear conveying frames 10, and a guide wheel 51 is movably connected to the top surface of the horizontal fixing plate 50 through a hinge shaft, and an elastic protective layer 52 is fixed on the outer wall of the guide wheel 51, and its rear wall is close to the front upper part of the groove 12.

[0039] The guide wheel 51 can prevent the wheel hub from being pushed too far forward when being pushed to the right. The elastic protective layer 52 of the guide wheel 51 can play a guiding and protective role, ensuring that the wheel hub can be normally transported along the horizontal conveying frame 20.
