Description

Technical Field

[0001] The invention relates to the technical field of instant noodle processing, and in particular to a black spot color sorting device used in an instant noodle production line. Background Art

[0002] Fast food is suitable for the needs of modern life rhythm and is deeply loved by people. Instant noodles have become the mainstream product of instant instruments. With the change of consumption concept, people have higher and higher requirements for the quality of instant noodles. In order to improve product quality, the noodles need to be inspected on both sides by color sorting device before packaging to filter out the noodles with black spots.

[0003] The color sorting device is a device that automatically sorts out different-colored particles in granular materials by using photoelectric detection technology based on the differences in the optical properties of the materials. In order to detect the upper and lower sides of the noodles, the color sorting device currently used in the instant noodle production line usually replaces the conveyor belt in the production line with a light-transmitting conveyor belt. However, debris will be generated during the transmission of the noodles on the conveyor belt, and after long-term use of this production line, the surface of the conveyor belt will be contaminated. In order to prevent the debris and contamination from affecting the accuracy of the color sorting device in detecting the lower surface of the noodles, the debris and contamination need to be removed in time.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Since the conveyor belt is multi-section, there are gaps between adjacent conveyor belts. The second color sorting mechanism for detecting the lower surface of the noodle cake is opposite to the gap. When the noodle cake is transmitted on the conveyor belt, the second color sorting mechanism can detect the lower surface of the noodle cake through the gap, replacing the existing color sorting device used in the instant noodle production line to use a light-transmitting conveyor belt to detect the lower surface of the noodle cake. Therefore, it effectively solves the problem that the dirt generated by the conveyor belt after long-term use will reduce the detection accuracy of the color sorting device and the problem that the conveyor belt needs to be stopped and removed for decontamination when cleaning the dirt. It can prevent the dirt on the conveyor belt from affecting the detection accuracy of the color sorting device and the conveyor belt does not need to be decontaminated, thereby reducing the labor intensity of workers and improving production efficiency.

[0015] 2. Since a light-transmitting member is provided in the cavity, the light-transmitting member is opposite to the gap, and the second color sorting mechanism is located below the light-transmitting member, when the noodles are transported on the conveyor belt and generate debris, the generated debris can pass through the gap and fall on the light-transmitting member, thereby preventing the debris from falling on the second color sorting mechanism and affecting the detection accuracy of the second color sorting mechanism, and when removing the debris, the light-transmitting member can be directly removed from the cavity for cleaning. Compared with cleaning the conveyor belt, the method of only cleaning the light-transmitting member greatly reduces the intensity of workers when removing dirt, because the scale of the light-transmitting member is much smaller than that of the conveyor belt and it is more convenient to remove. Therefore, the problem of inconvenient dirt removal of the existing color sorting device used on the instant noodle production line is effectively solved, thereby reducing the labor intensity of workers when removing dirt.

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] like Figures 1 to 5 As shown, the present invention discloses a black spot color sorting device for an instant noodle production line, comprising a shell 1 and a conveyor belt 2, wherein a cavity 3 is provided in the shell 1, an opening communicating with the cavity 3 is provided at the top of the shell 1, the conveyor belt 2 is located above the opening, a first color sorting mechanism 4 for detecting the upper surface of the noodle cake is provided above the conveyor belt 2, a second color sorting mechanism 5 for detecting the lower surface of the noodle cake is provided in the cavity 3, the conveyor belt 2 is multi-sectioned, a gap 6 is provided between adjacent conveyor belts 2, the second color sorting mechanism 5 is opposite to the gap 6, a light-transmitting member 7 is provided in the cavity 3, the light-transmitting member 7 is opposite to the gap 6, and the second color sorting mechanism 5 is opposite to the gap 6. The color sorting mechanism 5 is located below the light-transmitting member 7. When the noodles are transported on the conveyor belt 2, the second color sorting mechanism 5 can detect the lower surface of the noodles through the gap 6, replacing the existing color sorting device used in the instant noodle production line that uses the light-transmitting conveyor belt 2 to detect the lower surface of the noodles. This can prevent the second color sorting mechanism 5 from being unable to effectively detect the lower surface of the noodles through the conveyor belt 2 after dirt is generated on the conveyor belt 2, and the dirt generated on the conveyor belt 2 will no longer affect the detection accuracy of the second color sorting mechanism 5, so there is no need to stop the conveyor belt 2 for decontamination. , thereby improving the production efficiency while reducing the labor intensity of workers in cleaning. The specific distance setting of the gap 6 should meet the requirements of not affecting the transmission of the cakes by the adjacent conveyor belt 2 and being able to reserve shooting time for the first color sorting mechanism 4 and the second color sorting mechanism 5. Therefore, the distance of the gap 6 is set to 20mm to 30mm for the best, so that it can not affect the transmission of the cakes by the adjacent conveyor belt 2 while being able to reserve shooting time for the first color sorting mechanism 4 and the second color sorting mechanism 5 to ensure its detection accuracy; the first color sorting mechanism 4 and the second color sorting mechanism 5 should be spaced The arrangement can reduce the requirements for the main controller's information processing capability, thereby reducing costs; when the dough is transported on the conveyor belt 2 and generates debris, the generated debris can fall on the light-transmitting member 7 through the gap 6, thereby preventing the debris from falling on the second color sorting mechanism 5 and affecting the detection accuracy of the second color sorting mechanism 5, and when removing the debris, the light-transmitting member 7 can be directly removed from the cavity 3 for cleaning. Compared with cleaning the conveyor belt 2, the method of only cleaning the light-transmitting member 7 greatly reduces the intensity of workers when removing dirt, because the scale of the light-transmitting member 7 is much smaller than that of the conveyor belt 2 and is more convenient to remove.

[0024] The first color sorting mechanism 4 and the second color sorting mechanism 5 are both industrial cameras with detection mechanisms inside, which can take high-frequency photos when the dough passes by. Since the distance of the gap 6 should not affect the transmission of the dough by the adjacent conveyor belt 2, the distance of the gap 6 cannot be too large. Compared with ordinary digital cameras, industrial cameras can take local photos of the dough continuously and quickly, so more images can be taken at a smaller distance, and the corresponding controller calculates and compares the color depth and transmittance of the captured images to determine whether there are black spots on the dough, thereby improving the detection accuracy of the first color sorting mechanism 4 and the second color sorting mechanism 5 on the upper surface and the lower surface respectively.

[0025] A base frame 8 and a locking piece are provided in the cavity 3, the light-transmitting piece 7 is fixed on the base frame 8, a through hole 81 is provided on the side wall of the base frame 8, and the locking piece passes through the through hole 81 to fix the base frame 8 to the side wall of the cavity 3. Since the conveyor belt 2 needs to be driven by an external motor, when the conveyor belt 2 rotates, the shell 1 will inevitably vibrate. The light-transmitting piece 7 is fixed on the base frame 8, and the base frame 8 can be more firmly installed on the side wall of the cavity 3 through fasteners, making installation and disassembly more convenient, and preventing the light-transmitting piece 7 from vibrating with the vibration of the shell 1, causing debris falling on the light-transmitting piece 7 to be vibrated into the cavity 3, making cleaning inconvenient.

[0026] It also includes a first fixing mechanism for fixing the first color sorting mechanism 4, the first fixing mechanism includes a support beam 91, a mounting plate 92, a reinforcing plate 93 and a first connecting rod 94, the support beams 91 are multiple and are arranged at intervals, one end of the support beam 91 is fixed to the side wall of the shell 1, and the other end first extends upward and then to one side as an extension end 911, the mounting plate 92 is fixed to the extension end 911, the reinforcing plate 93 is bent and includes a fixing portion 931 and a mounting portion 932, the fixing portion 931 is fixed to the mounting plate 92, and the mounting portion 932 is provided with a light source for improving the shooting accuracy, one end of the first connecting rod 94 is fixed to the mounting plate 92, and the other end is sleeved with a first slider 95, the inner wall of the first slider 95 is against the outer wall of the first connecting rod 94 and forms a sliding fit, and the first color sorting mechanism 4 is fixed to the outer wall of the first slider 95, Since the conveyor belt 2 needs to be driven by an external motor, when the conveyor belt 2 rotates, the shell 1 will inevitably vibrate. The first color fixing mechanism can stably fix the first color sorting mechanism 4 above the conveyor belt 2, thereby preventing the first color sorting mechanism 4 from vibrating with the vibration of the shell 1, thereby improving the detection accuracy of the first color sorting mechanism 4 when detecting the upper surface of the dough cake, and the light source fixed on the mounting portion 932 can provide fill light for the first color sorting mechanism 4 and the second color sorting mechanism 5 when detecting the dough cake, thereby improving the detection accuracy of the first color sorting mechanism 4 and the second color sorting mechanism 5 on the dough cake in a dark environment, and the first color sorting mechanism 4 can adjust the relative position with the conveyor belt 2 through the first slider 95 to ensure that the conveyor belt 2 can be opposite to the dough cake when transferring the dough cake to the first color sorting mechanism 4, thereby improving the detection accuracy.

[0027] The second color sorting mechanism 5 is fixed to the outer wall of the first connecting rod 94 and forms a sliding fit. The second color sorting mechanism 5 is fixed to the outer wall of the second slider 102. Since the conveyor belt 2 needs to be driven by an external motor, when the conveyor belt 2 rotates, the shell 1 inevitably vibrates. The second color fixing mechanism can stably fix the second color sorting mechanism 5 under the conveyor belt 2, thereby preventing the second color sorting mechanism 5 from vibrating with the vibration of the shell 1, thereby improving the detection accuracy of the second color sorting mechanism 5 when detecting the lower surface of the cake, and the second color sorting mechanism 5 can adjust the relative position with the conveyor belt 2 through the second slider 102, ensuring that the conveyor belt 2 can be opposite to the cake when transmitting the cake to the second color sorting mechanism 5, thereby improving the detection accuracy.

[0028] The shading mechanism also includes a mounting frame (not shown in the figure) and a shading plate 202. The mounting frame (not shown in the figure) is fixed on the mounting plate 92. The shading plate 202 is fixed on the mounting frame (not shown in the figure). The front wall of the shading plate 202 is an openable flip structure. Hinges 203 are provided on both sides of the front wall of the mounting frame (not shown in the figure). One end of the hinge 203 is fixed on the mounting frame (not shown in the figure), and the other end is fixed on the shading plate 202. Since the first color sorting mechanism 4 is installed above the conveyor belt 2 and is greatly affected by external light, the shading plate 202 is installed on the mounting frame (not shown in the figure) to effectively reduce the influence of external light on the first color sorting mechanism 4, thereby improving the first color sorting mechanism 4. The detection accuracy of a color sorting mechanism 4 is improved, and the shading plate 202 on one side can be flipped through the hinge 203, so that the first color sorting mechanism 4 located in the shading plate 202 can be easily maintained or the position can be adjusted, making it more user-friendly, wherein the shading plate 202 is also made of opaque material, so as to effectively reduce the influence of external light on the first color sorting mechanism 4; the shading plate 202 contains magnets, and the mounting frame (not shown in the figure) is made of a metal material that can be adsorbed by magnets, so that when the shading frame is closed, the magnets in the shading frame can stably adsorb the shading frame to the mounting frame (not shown in the figure), and a damping feeling will be generated when opening or closing, thereby improving the feel of use.

[0029] The system also includes a recycling mechanism for removing and collecting dough cakes with black spots, the recycling mechanism including an air nozzle 301 and a collection box 302, the air nozzle 301 is fixed on the shell 1 and is located downstream of the first color sorting mechanism 4 and the second color sorting mechanism 5, the collection box 302 is fixed to the side wall of the shell 1, a recycling port 3021 is provided on the collection box 302, the recycling port 3021 is opposite to the air nozzle 301, and the collection box 302 is provided with an openable flap 3022 on the other side of the recycling port 3021. When one of the first color sorting mechanism 4 and the second color sorting mechanism 5 detects the presence of black spots on the dough cake, the recycling port 3021 can be removed. An output signal is sent to the controller that controls the entire instant noodle production line. The controller receives the output signal and automatically controls the air nozzle 301 to remove the noodle cakes with black spots, thereby reducing the labor intensity of the workers. The recycling port 3021 on the collection box 302 is opposite to the air nozzle 301. When the air nozzle 301 removes the noodle cakes, the removed noodle cakes can fall into the collection box 302 through the recycling port 3021, and the removed instant noodles in the collection box 302 can be taken out by opening the flap 3022, thereby facilitating the concentration of instant noodles with black spots and improving processing efficiency.

[0030] The use process and principle of the present invention are as follows:

[0031] The relative positions of the first color sorting mechanism 4, the second color sorting mechanism 5 and the conveyor belt 2 are adjusted respectively by the first slider 95 and the second slider 102 to ensure that when the dough cake is transmitted to the first color sorting mechanism 4 and the second color sorting mechanism 5 through the conveyor belt 2, the first color sorting mechanism 4 and the second color sorting mechanism 5 can be opposite to the dough cake, wherein the signal lines of the first color sorting mechanism 4 and the second color sorting mechanism 5 are connected to the controller controlling the production line. Then, when the dough cake is transmitted to the second color sorting mechanism 5 through the conveyor belt 2, the second color sorting mechanism 5 detects the dough cake and takes a high-speed video of the lower surface of the dough cake to determine the color depth and light transmittance of the dough cake, and compares the amplitude of the light change. When the amplitude exceeds the value set in the controller, the second color sorting mechanism 5 sends an output signal to the controller, and the controller receives and processes the output signal. Then, when the dough cake passes through the first color sorting mechanism 4, the first color sorting mechanism 4 detects the upper surface of the dough cake, and its detection principle is consistent with that of the second color sorting mechanism 5. When the first color sorting mechanism 4 and the second color sorting mechanism 5 are After the detection of the same dough cake is completed, the controller determines whether to control the air nozzle 301 to remove the dough cake according to whether the output signal from the first color sorting mechanism 4 or the second color sorting mechanism 5 is received. When the controller receives the output signal and the first color sorting mechanism 4 and the second color sorting mechanism 5 have completed the detection of the dough cake, the air nozzle 301 is started and the dough cake with problems is removed to the collection box 302 opposite to the air nozzle 301. The worker can manually open the flap 3022 to remove the dough cake in the collection box 302, thereby improving the processing efficiency of the dough cake with problems. The detection sequence of the first color sorting mechanism 4 and the second color sorting mechanism 5 can be replaced, and when the present invention is running, the light source is started to supplement the first color sorting mechanism 4 and the second color sorting mechanism 5 to improve the detection accuracy of the first color sorting mechanism 4 and the second color sorting mechanism 5, and the first color sorting mechanism 4 located above the conveyor belt 2 is located in the light shielding plate 202, which can effectively reduce the interference of external light and improve the detection accuracy of the first color sorting mechanism 4.
