[0032] In the description of the present application, it should be noted that, for orientation words, such as terms “center”, “transverse”, “longitudinal”, “length”, “width”, “thickness”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, “clockwise”, “counterclockwise”, etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0033] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0034] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0035] The following description, in conjunction with the accompanying drawings, further illustrates this application:

[0036] like Figures 1 to 8 As shown, this application provides an automatic loading and unloading cam plate processing machine tool, including: a loading device 1, adapted to convey cam plates 6; a sorting device 2, adapted to receive the cam plates 6 conveyed by the loading device 1 and screen the cam plates 6, sorting the cam plates 6 that meet the feeding requirements at the feeding position; a feeding device 3, adapted to convey the cam plates 6 at the feeding position to the processing device 4; a processing device 4, adapted to process the cam plates 6 fed in by the feeding device 3; and an unloading device 5, adapted to receive and convey the cam plates 6 processed at the processing device 4.

[0037] The sorting device 2 enables fully automatic loading and unloading of cam plates 6. Cam plates 6 that meet the feeding requirements can enter the processing device 4 for processing, while cam plates 6 that do not meet the feeding requirements can be continuously sorted in a loop at the sorting device 2 and the loading device 1 until they meet the feeding requirements. The entire device has a simple and compact structure, low layout cost, and high practicality.

[0038] like Figures 1 to 3 In the embodiment shown, the feeding device 1 includes a feeding hopper 11 and a feeding conveyor belt 12. The feeding side of the feeding conveyor belt 12 is located inside the feeding hopper 11, and the discharging side of the feeding conveyor belt 12 is located above the first sorting mechanism 21.

[0039] like Figures 2 to 3 In the embodiment shown, the feeding conveyor belt 12 is arranged at an angle, and a baffle 121 is provided on the feeding conveyor belt 12. The baffle 121 is arranged perpendicular to the conveying direction of the feeding conveyor belt 12, and the baffle 121 can help the cam plate 6 to be lifted up along the feeding conveyor belt 12.

[0040] like Figures 2 to 3In the embodiment shown, a discharge chute 13 is provided between the discharge side of the feeding conveyor belt 12 and the first sorting mechanism 21. The cam plate 6 on the feeding conveyor belt 12 is adapted to slide down the discharge chute 13 onto the first sorting mechanism 21. The discharge chute 13 is used to guide the movement of the cam plate 6. Multiple material columns 131 are spaced apart in the discharge chute 13. The interval between adjacent material columns 131 is greater than the maximum outer diameter of the cam plate 6. The material columns 131 are used to break up the cam plate 6 so that the cam plate 6 can fall onto the first sorting mechanism 21 as dispersedly as possible, thereby improving the success rate of subsequent screening and sorting, and thus improving the feeding efficiency.

[0041] like Figure 4 In the illustrated embodiment, the sorting device 2 includes a first sorting mechanism 21 and a second sorting mechanism 22 connected to each other. When the cam plate 6 falls onto the first sorting mechanism 21, with the operation of the first sorting mechanism 21 and the second sorting mechanism 22, the cam plate 6 is adapted to pass through the first sorting mechanism 21 and the second sorting mechanism 22 in sequence. When the cam plate 6 moves from the first sorting mechanism 21 to the second sorting mechanism 22, it is adapted to switch states. The first sorting mechanism 21 is provided with a first channel 211, which is adapted to allow the cam plate 6 in the first state to pass through. The second sorting mechanism 22 is provided with a second channel 221, which is adapted to allow the cam plate 6 in the second state to pass through. Through the cooperation of the first sorting mechanism 21 and the second sorting mechanism 22, the cam plate 6 can be screened and eliminated for a second time by combining the state transition with the obstruction of the first channel 211 and the second channel 221, so that the final state of the cam plate 6 can meet the feeding conditions.

[0042] In this application, the cam plate 6 in the first state is in a horizontal position, and the first channel 211 can only allow a single horizontally positioned cam plate 6 to pass through. The cam plate 6 in the second state is in a vertical position. Since the cam plate 6 has protrusions, the protrusions of the cam plate 6 in the vertical position have different orientations. The second channel 221 can block cam plates 6 whose protrusion orientation does not meet the feeding conditions. Through the first channel 211 and the second channel 221, the feeding state of the cam plate 6 can be unified.

[0043] like Figure 5 In the embodiment shown, the first sorting mechanism 21 includes a sorting conveyor belt 212 and a first limiter 213. The sorting conveyor belt 212 is adapted to transport cam pieces 6. The first limiter 213 is located above the sorting conveyor belt 212. A first channel 211 is formed between the first limiter 213 and the sorting conveyor belt 212. The height of the first channel 211 is not less than the thickness of a single cam piece 6 and less than the thickness of two cam pieces 6, so that the cam pieces 6 can pass through the first channel 211 individually and sequentially, avoiding the phenomenon of cam pieces 6 stacking and passing through.

[0044] like Figure 5In the shown embodiment, the first restrictor 213 is provided with an inclined portion 2131 on the side facing the feeding side of the sorting conveyor 212, which is adapted to guide the cam pieces 6 that do not pass through the first passage 211 to one side away from the sorting conveyor 212. A first recovery chute 224 is provided between the first sorting mechanism 21 and the feeding device 1, and one end of the first recovery chute 224 is connected to one side of the sorting conveyor 212. The first recovery chute 224 is adapted to receive the cam pieces 6 that are guided to one side away from the sorting conveyor 212. In order to avoid the stacking of the cam pieces 6 in front of the first passage 211, the inclined portion 2131 is provided on the first restrictor 213, so that the cam pieces 6 blocked by the first restrictor 213 can be guided to the first recovery chute 224 for recovery and re-feeding, thereby ensuring the normal operation of the first sorting mechanism 21.

[0045] As shown in the embodiment, Figure 5 In the shown embodiment, the first recovery chute 224 is provided with a guide plate 214 on the side facing the discharging side of the sorting conveyor 212. The guide plate 214 is inclined towards the first recovery chute 224 on the side close to the discharging side of the sorting conveyor 212. The guide plate 214 is adapted to guide the cam pieces 6 that pass through the first passage 211 to converge on the sorting conveyor 212, thereby avoiding the falling of some cam pieces 6 into the first recovery chute 224 after passing through the first passage 211, and improving the success rate and efficiency of the sorting and screening of the cam pieces 6.

[0046] In some embodiments, the second sorting mechanism 22 includes a vibrating conveyor 222 and a second restrictor 223. The vibrating conveyor 222 is adapted to convey the cam pieces 6. The second restrictor 223 is located above the vibrating conveyor 222, and a second passage 221 is formed between the second restrictor 223 and the vibrating conveyor 222. The vibrating conveyor 222 is provided with a discharging gap 2221. The vibrating conveyor 222 has a specific structure composed of two parallel vibrating conveying rollers. The discharging gap 2221 is formed between the two vibrating conveying rollers. The second restrictor 223 is adapted to make the cam pieces 6 that do not pass through the second passage 221 fall from the discharging gap 2221.

[0047] As shown in the embodiment, Figure 6 In the shown embodiment, the discharging gap 2221 is adapted to accommodate the protruding portions on the cam pieces 6, so that the cam pieces 6 can be stably conveyed along the vibrating conveyor 222 with the protruding portions facing downwards. The cam pieces 6 with the protruding portions facing to the two sides or upwards can be blocked by the second restrictor 223 and flipped to fall from the discharging gap 2221.

[0048] As shown in the embodiment, Figure 7In the embodiment shown, in conjunction with the specific structural design of the vibrating conveyor 222, the conveying surface of the sorting conveyor belt 212 can be designed to be higher than the conveying surface of the vibrating conveyor 222. The height difference between the sorting conveyor belt 212 and the vibrating conveyor 222 is used to realize the flipping of the cam plate 6, thereby realizing the state switching of the cam plate 6, so that the cam plate 6 can change from the horizontal state of the first state to the vertical state of the second state. The cam plate 6 that fails to change state cannot be stabilized on the vibrating conveyor 222 and will fall from the material drop gap 2221, realizing the initial screening and rejection.

[0049] like Figure 6 In the embodiment shown, the second limiter 223 includes a first baffle 2231 and a second baffle 2232. The first baffle 2231 and the second baffle 2232 are located on both sides of the material drop gap 2221, respectively. The outer side of the first baffle 2231 and the outer side of the second baffle 2232 are both inclined towards the feeding side of the vibrating conveyor 222, so that when the cam plate 6 is blocked by the first baffle 2231 and / or the second baffle 2232, it can converge and fall into the material drop gap 2221, reducing the probability of the cam plate 6 falling out of the vibrating conveyor 222.

[0050] In some embodiments, the tilt angle of the first baffle 2231 and the second baffle 2232 is adjustable in order to change the converging effect of the first baffle 2231 and the second baffle 2232.

[0051] like Figure 4 and 6 In the embodiment shown, the first baffle 2231 and the second baffle 2232 are staggered along the direction of the vibrating conveyor 222 conveying the cam plate 6 to limit the first baffle 2231 and the second baffle 2232 from contacting the cam plate 6 at the same time. The first baffle 2231 and the second baffle 2232 are respectively used to block the cam plates 6 with protrusions facing different directions. The staggered distribution of the first baffle 2231 and the second baffle 2232 enables the cam plate 6 to flip and fall left and right, reducing the probability of the cam plate 6 stopping at the first baffle 2231 and the second baffle 2232, and improving the smoothness of the screening and sorting.

[0052] like Figure 4 and 6 In the embodiment shown, the upper part of the first baffle 2231 is inclined toward the feeding side of the vibrating conveyor 222; the upper part of the second baffle 2232 is inclined toward the feeding side of the vibrating conveyor 222, so that the cam plate 6 can be flipped down into the material drop gap 2221 in a downward manner, avoiding the cam plate 6 from being stuck at the first baffle 2231 and the second baffle 2232, and improving the smoothness of screening and sorting.

[0053] like Figure 8In the embodiment shown, the second limiter 223 comprises an induction patch 2233 and an air outlet 2234, the induction patch 2233 is located above the vibrating conveyor 222, a second channel 221 is formed between the induction patch 2233 and the vibrating conveyor 222, and the air outlet 2234 is located on one side of the vibrating conveyor 222, the air outlet 2234 is adapted to turn on the powered air when the induction patch 2233 contacts the cam piece 6, so that the cam piece 6 is deflected and falls from the material falling gap 2221, that is, the cam piece 6 not in the second state can be identified by the induction patch 2233 and flipped by the air outlet 2234.

[0054] As shown in the embodiments of Figure 2 and 3 , a second recovery chute 225 is arranged between the second sorting mechanism 22 and the feeding device 1, one end of the second recovery chute 225 is located below the material falling gap 2221, the second recovery chute 225 is adapted to receive the cam piece 6 falling from the material falling gap 2221, and the recovered cam piece 6 can be re-fed by the feeding device 1 to the first sorting mechanism 21 for re-screening and sorting.

[0055] As shown in the embodiments of Figure 2 and 3 , a plurality of guide rollers 2251 are arranged on the second recovery chute 225, the guide rollers 2251 are adapted to guide the cam piece 6 to slide along the second recovery chute 225, since the second recovery chute 225 is connected below the vibrating conveyor 222, the inclination angle is low, the guide rollers 2251 can improve the smoothness of the second recovery chute 225 conveying the cam piece 6 and reduce the probability of blockage.

[0056] As shown in the embodiments of Figure 2 and 3In the shown embodiment, the sorting device 2 comprises a blocking mechanism 226, which comprises a blocker 2261, a shutter 2262 and a sensor 2263. The blocker 2261 is arranged at the discharge side of the second sorting mechanism 22 and is adapted to limit the movement of the cam pieces 6 on the second sorting mechanism 22. The shutter 2262 is arranged above the second sorting mechanism 22 and forms a feeding gap 2264 with the blocker 2261. The feeding gap 2264 is not less than the thickness of a single cam piece 6 and is less than the thickness of two cam pieces 6. The sensor 2263 is connected to the feeding device 1 and / or the first sorting mechanism 21 and is spaced apart from the blocker 2261 by an integer multiple of the thickness of a cam piece 6. The blocking mechanism 226 is used to help the cam pieces 6 to be arranged in order at the discharge side of the second sorting mechanism 22, so as to facilitate the feeding device 3 to take the feed. The shutter 2262 is used to ensure that the cam piece 6 at the front can be taken. The sensor 2263 can control the operation and stop of the feeding device 1 and / or the first sorting mechanism 21. When there are too many cam pieces 6 at the feeding position, the feeding device 1 can be stopped to avoid the accumulation of the cam pieces 6.

[0057] In some embodiments, the feeding device 3 comprises a feeding manipulator, a feeding clamp and a feeding conveyor belt. The feeding manipulator and the feeding clamp are arranged at the feeding side of the feeding conveyor belt. The discharge side of the feeding conveyor belt is connected to the processing equipment. The feeding manipulator is adapted to take the cam piece 6 in the second state at the feeding position after passing through the second passage 221 and place it in the feeding clamp. The feeding clamp is adapted to convey the cam piece 6 to the feeding conveyor belt.

[0058] In the present application, the feeding clamp is a turnover clamp. The opening of the feeding clamp in the initial state is upward, which is used to receive the cam piece 6 in the second state. The feeding clamp is adapted to turn over and dump the cam piece 6 onto the feeding conveyor belt.

[0059] In some embodiments, the processing equipment can be provided with a quenching station, a tempering station and a processing manipulator. The quenching station and the tempering station are adapted to perform surface treatment on the cam piece 6. The processing manipulator is adapted to transfer the cam piece 6 on the feeding conveyor belt to the quenching station or transfer the cam piece 6 on the tempering station to the discharge device 5.

[0060] In some embodiments, the discharge device 5 comprises a discharge conveyor belt, which is adapted to receive and convey the processed cam piece 6.
