Description

Technical Field

[0001] The invention relates to the technical field of biscuit production, and in particular to a low-sugar biscuit defect detection device using optical means. Background Art

[0002] Biscuits are a common food in our daily life. After the production is completed, there are often some incomplete biscuits with defects, or overweight or underweight biscuits that deviate from the design threshold. Therefore, before packaging, in order to ensure the quality of the product, the biscuits need to be inspected to confirm the integrity of the biscuits and the compliance of the single piece weight.

[0003] In the prior art, biscuits are inspected manually, and defective products are manually removed during the manual inspection. However, during manual inspection, some small defects or deviations in the weighing process are prone to missed inspections or wrong inspections during a large amount of inspection work. In addition, the biscuits need to be turned over during the manual inspection to inspect both sides of the biscuits. This has low inspection efficiency and is unhygienic.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a low-sugar biscuit defect detection device using optical means is proposed. Summary of the invention

[0005] The object of the present invention is to provide a low-sugar biscuit defect detection device using optical means to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a low-sugar biscuit defect detection device using optical means, comprising a turntable and a gravity sorting mechanism, wherein the outer edge array of the turntable is provided with four inner grooves, and the gravity sorting mechanism is correspondingly arranged below the openings of the inner grooves, and the gravity sorting mechanism comprises a support plate, a transparent plate, a rubber pad, a support and a counterweight block, a transparent plate is embedded in the middle of the front end of the support plate, and rubber pads are bonded to both sides of the front end of the support plate, the two sides of the rear end of the support plate rotate inside the support, and a counterweight block is magnetically fixed to the middle of the rear end of the support plate.

[0007] Furthermore, an access port is connected to the rear end of the upper opening of the inner groove, and the access port is communicated with the rear side wall of the inner groove through a lateral air duct of an "L"-shaped structure.

[0008] Furthermore, the turntable is coaxially fixed to the top end of the sleeve, and a slewing bearing is coaxially fixed to the bottom end of the sleeve, and the outer ring tooth shape of the slewing bearing meshes with the gear rod at the output end of the drive motor for transmission.

[0009] Furthermore, a wind sorting mechanism is provided inside the sleeve, and the wind sorting mechanism includes a cylinder and a telescopic rod. The cylinder is placed in the internal cavity of the sleeve, and the outer diameter of the cylinder body is smaller than the inner diameter of the sleeve center hole, and the telescopic rod is fixedly connected to the output end of the cylinder.

[0010] Furthermore, the wind sorting mechanism also includes an end plate, a gas distributor and an air source interface. The end of the telescopic rod is fixedly connected to the end plate, and the middle end of the end plate is fixedly installed with a gas distributor, and the end of the gas distributor is connected to the positive pressure air source through the air source interface.

[0011] Furthermore, the wind sorting mechanism also includes a branch pipe and an output port. The air source interface is connected to the two sides with a branch pipe, and the ends of the branch pipe are respectively connected to the output ports located on both sides of the end plate, and the output ports are respectively connected to the corresponding access ports.

[0012] Furthermore, a discharge barrel is correspondingly arranged above the inner groove at the first position of the turntable, and biscuit bodies are stacked up and down inside the discharge barrel, and a heavy waste frame is correspondingly arranged at the opening below the discharge barrel.

[0013] Furthermore, a bracket is correspondingly arranged on the side surface of the inner groove of the turntable at the secondary position, and a detection host is fixedly installed on the top of the bracket.

[0014] Furthermore, visual cameras are relatively arranged at the upper and lower ends of the front part of the bracket recess, and the visual camera located at the upper end directly faces the upper end surface of the biscuit body, and the visual camera located at the lower end faces the lower end surface of the biscuit body through the transparent plate, and a defect waste frame is arranged at the rear part of the bracket recess.

[0015] Furthermore, a conveyor belt is correspondingly arranged on the side surface of the inner groove where the turntable is in the last position, and a guide plate is externally connected to the side plate of the conveyor belt away from the turntable, and a lightweight waste frame is arranged at the end of the inclined surface of the guide plate.

[0016] The present invention provides a low-sugar biscuit defect detection device using optical means, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the fulcrum of the support plate is designed in the support on the rear side, so that the power arm of the lever structure composed of the support plate, the support and the counterweight block is longer than the resistance arm. In this way, when the weight of the biscuit body is between the design threshold or less than the design threshold, the support plate maintains balance so that the biscuit body can rotate synchronously with the turntable to switch to the next station. When the weight of the biscuit body exceeds the design threshold, that is, it is overweight, the support plate loses balance and tilts forward, so that the overweight biscuit body falls into the heavy waste frame below. The present application combines the quantitative discharging of the discharge barrel and the groove in the circumference of the turntable with the sorting of the overweight material under the action of the gravity sorting mechanism through the cooperation of the gravity sorting mechanism and the discharge barrel, so that the overweight material is discharged synchronously while the quantitative discharging is carried out, thereby realizing the preliminary weight detection of the biscuit body.

[0018] 2. During the use of the present invention, on the one hand, the present application utilizes the air selection principle to perform a secondary weight detection on the biscuit body, that is, the biscuit body between the design thresholds will fall between the conveyor belts to achieve discharge, while the biscuit body that is smaller than the design threshold, that is, lighter, will fall into the light waste frame under the guidance of the guide plate. By developing and utilizing the lever principle and the air selection principle, the biscuit body that deviates from the design threshold can be identified and discharged without using complex sensors, and the lighter or heavier biscuit bodies can be classified and collected for subsequent processing. On the other hand, wind power is simultaneously provided for the discharge of biscuit bodies with defects in visual inspection. The design of one machine with two uses simplifies the device structure, improves the linkage between different functional mechanisms, and the structural design in which the gas is blown out from the rear side wall of the inner groove can clean the upper surface of the transparent plate during the discharge of the biscuit body to avoid the residual biscuit residues interfering with subsequent detection, thereby ensuring the detection accuracy.

DETAILED DESCRIPTION

[0026] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0027] See also Figures 1 to 4 The present invention provides a technical solution: a low-sugar biscuit defect detection device using optical means, comprising a turntable 1 and a gravity sorting mechanism 3, wherein the outer edge array of the turntable 1 is provided with four inner grooves 2, and the gravity sorting mechanism 3 is correspondingly arranged below the opening of the inner groove 2, and the gravity sorting mechanism 3 comprises a support plate 301, a transparent plate 302, a rubber pad 303, a support 304 and a counterweight 305, wherein a transparent plate 302 is embedded in the middle of the front end of the support plate 301, and rubber pads 303 are bonded to both sides of the front end of the support plate 301, and both sides of the rear end of the support plate 301 rotate inside the support 304, and a counterweight 305 is magnetically fixed to the middle of the rear end of the support plate 301, and a discharge barrel 10 is correspondingly arranged above the inner groove 2 of the turntable 1 at the first position, and biscuit bodies 11 are stacked up and down inside the discharge barrel 10, and a heavy waste frame 12 is correspondingly arranged at the opening below the discharge barrel 10;

[0028] The specific operation is as follows: the gear rod at the output end of the driving motor 8 is meshed with the outer ring tooth shape of the slewing bearing 7, and then drives the top turntable 1 to rotate intermittently through the sleeve 6. During the intermittent rotation of the turntable 1, when the inner groove 2 rotates to just below the discharge barrel 10 in the first position, the biscuit body 11 in the discharge barrel 10 falls into the inner groove 2 below the opening and is received by the support plate 301. The quantitative discharging is achieved by designing the thickness of the inner groove 2 to allow only one piece of biscuit body 11 to be placed. In this application, the fulcrum of the support plate 301 is designed in the support 304 on the rear side, so that the power arm of the lever structure composed of the support plate 301, the support 304 and the counterweight block 305 is longer than the resistance arm. When the weight of the dry body 11 is between the design thresholds or less than the design thresholds, the support plate 301 maintains balance so that the biscuit body 11 can rotate synchronously with the turntable 1 and switch to the next station. When the weight of the biscuit body 11 exceeds the design threshold, that is, it is overweight, the support plate 301 loses balance and tilts forward, causing the overweight biscuit body 11 to fall into the heavy waste frame 12 below. The present application combines the quantitative discharging of the discharge barrel 10 and the groove 2 in the circumference of the turntable 1 with the sorting of the overweight material under the action of the gravity sorting mechanism 3 through the cooperation of the gravity sorting mechanism 3 and the discharge barrel 10, so that the overweight material is discharged synchronously during the quantitative discharging, thereby realizing the preliminary weight detection of the biscuit body 11.

[0029] See also Figures 2 to 6The rear end of the upper opening of the inner groove 2 is connected with an access port 4, and the access port 4 is connected with the rear side wall of the inner groove 2 through an "L"-shaped lateral air duct 5. The turntable 1 is coaxially fixed to the top of the sleeve 6, and a slewing bearing 7 is coaxially fixed to the bottom of the sleeve 6, and the outer ring tooth shape of the slewing bearing 7 is meshed with the gear rod at the output end of the driving motor 8 for transmission. A wind sorting mechanism 9 is arranged inside the sleeve 6, and the wind sorting mechanism 9 includes a cylinder 901 and a telescopic rod 902. The cylinder 901 is arranged The cylinder 901 is in the inner cavity of the sleeve 6, and the outer diameter of the cylinder 901 is smaller than the inner diameter of the hole in the sleeve 6, and the output end of the cylinder 901 is fixedly connected with a telescopic rod 902, and the wind sorting mechanism 9 also includes an end plate 903, a gas distributor 904 and a gas source interface 905, the end of the telescopic rod 902 is fixedly connected with the end plate 903, and the middle end of the end plate 903 is fixedly installed with a gas distributor 904, and the end of the gas distributor 904 is connected to the positive pressure gas source through the gas source interface 905, and the wind sorting mechanism 9 also includes an end plate 903, a gas distributor 904 and a ... The sorting mechanism 9 also includes a branch pipe 906 and an output port 907. The two sides of the gas source interface 905 are connected with branch pipes 906, and the ends of the branch pipes 906 are respectively connected with the output ports 907 located on the two sides of the end plate 903, and the output ports 907 are respectively connected with the corresponding access ports 4. A bracket 13 is correspondingly arranged on the side of the inner groove 2 of the turntable 1 in the second position, and a detection host 14 is fixedly installed on the top of the bracket 13. Visual cameras 15 are relatively arranged at the upper and lower ends of the front of the notch of the bracket 13, and the visual camera 15 located at the upper end directly faces the upper end surface of the biscuit body 11, and the visual camera 15 located at the lower end faces the lower end surface of the biscuit body 11 through the transparent plate 302. A defective waste frame 16 is arranged at the rear of the notch of the bracket 13. A conveyor belt 17 is correspondingly arranged on the side of the inner groove 2 of the turntable 1 in the last position, and a guide plate 18 is externally connected to the side plate of the conveyor belt 17 away from the end of the turntable 1, and a lightweight waste frame 19 is arranged at the end of the inclined surface of the guide plate 18;

[0030] The specific operation is as follows. With the rotation of the turntable 1, the biscuit body 11 to be inspected is transferred to the inside of the recess of the bracket 13 in the second position. The present application adopts the structural design of embedding a transparent plate 302 at the front end of the support plate 301, and through the visual cameras 15 relatively arranged at the upper and lower ends of the front of the recess, the visual inspection of the end faces of the biscuit body 11 on both sides can be realized through the transparent plate 302. The image is captured by the built-in optical sensor of the visual camera 15 and converted into an electronic signal and transmitted to the detection host 14 for further identification and processing, so that the biscuit body 11 with defects is identified. Thereafter, the turntable 1 rotates again and finally arrives above the conveyor belt 17 in the last position after manual re-inspection. At this time, the cylinder 901 inside the sleeve 6 is activated and the top end plate 903 is retracted through the telescopic rod 902. The gas distributor 904 in the middle of the end plate 903 is connected with the output ports 907 at both ends through the branch pipe 906, and is further connected with the corresponding position access port 4 through the output port 907, so that the gas enters from the rear side wall of the inner groove 2. The biscuit body 11 is blown away. On the one hand, the present application utilizes the air selection principle to perform a secondary weight detection on the biscuit body 11, that is, the biscuit body 11 between the design thresholds will fall between the conveyor belts 17 to realize discharge, and the biscuit body 11 that is smaller than the design threshold, that is, lighter, will fall into the light waste frame 19 under the guidance of the guide plate 18. By developing and utilizing the lever principle and the air selection principle, the biscuit body 11 that deviates from the design threshold can be identified and discharged without using complex sensors, and the lighter or heavier biscuit bodies 11 can be classified and collected for subsequent processing. On the other hand, wind power is simultaneously provided for the discharge of the biscuit body 11 with defects in visual inspection. The design of one machine with two uses simplifies the device structure, improves the linkage between different functional mechanisms, and the structural design in which the gas is blown out from the rear side wall of the inner groove 2 can clean the upper surface of the transparent plate 302 during the discharge of the biscuit body 11, so as to avoid the residual biscuit residues from interfering with subsequent detection and ensure the detection accuracy.

[0031] In summary, when using the low-sugar biscuit defect detection device using optical means, the gear rod at the output end of the driving motor 8 meshes with the outer ring tooth shape of the slewing bearing 7, and then drives the top turntable 1 to rotate intermittently through the sleeve 6. During the intermittent rotation of the turntable 1, when the inner groove 2 rotates to just below the discharge barrel 10 in the first position, the biscuit body 11 in the discharge barrel 10 falls into the inner groove 2 below the opening and is received by the support plate 301. Quantitative discharging is achieved by designing the thickness of the inner groove 2 to allow only one biscuit body 11 to be placed. In this application, the fulcrum of the support plate 301 is designed in the support 304 on the rear side, so that the power arm of the lever structure composed of the support plate 301, the support 304 and the counterweight block 305 is longer than the resistance arm. When the weight of the biscuit body 11 is between the design thresholds or less than the design thresholds, the support plate 301 maintains balance so that the biscuit body 11 can rotate synchronously with the turntable 1 to switch to the next workstation. When the weight of the biscuit body 11 exceeds the design threshold, that is, it is overweight, the support plate 301 loses balance and tilts forward, causing the overweight biscuit body 11 to fall into the heavy waste frame 12 below. The present application combines the quantitative discharging of the discharge barrel 10 and the groove 2 in the circumference of the turntable 1 with the sorting of overweight materials by the gravity sorting mechanism 3 through the cooperation of the gravity sorting mechanism 3 and the discharge barrel 10. The overweight materials are discharged synchronously during the quantitative discharging, thereby realizing the preliminary weight detection of the biscuit body 11. As the turntable 1 rotates, the biscuit body to be detected is discharged. The body 11 is transferred to the inside of the recess of the bracket 13 in the secondary position. The present application adopts the structural design of embedding a transparent plate 302 at the front end of the support plate 301, and through the visual cameras 15 arranged relatively at the upper and lower ends of the front of the recess, the visual inspection of the end faces of both sides of the biscuit body 11 can be realized through the transparent plate 302. The image is captured by the built-in optical sensor of the visual camera 15 and converted into an electronic signal and transmitted to the detection host 14 for further identification and processing, and the defective biscuit body 11 is identified. Thereafter, the turntable 1 rotates again and finally arrives above the conveyor belt 17 in the last position after manual re-inspection. At this time, the cylinder 901 inside the sleeve 6 is activated and the top end plate 903 is retracted through the telescopic rod 902. The gas distributor 904 in the middle of the end plate 903 is distributed The branch pipe 906 is connected with the output ports 907 at both ends, and further through the socket connection of the output ports 907 and the corresponding position access port 4, the gas enters from the rear side wall of the inner groove 2 and blows away the biscuit body 11. On the one hand, the present application uses the air selection principle to perform a secondary weight detection on the biscuit body 11, that is, the biscuit body 11 between the design thresholds will fall between the conveyor belt 17 to achieve discharge, and the biscuit body 11 that is smaller than the design threshold, that is, the light biscuit body 11 will fall into the light waste frame 19 under the guidance of the guide plate 18. By developing and utilizing the lever principle and the air selection principle, the biscuit body 11 that deviates from the design threshold can be identified and discharged without using complex sensors, and the light or heavy biscuit bodies 11 can be classified and collected for subsequent processing.On the other hand, it also provides wind for the discharge of defective biscuit bodies 11 during visual inspection. The dual-purpose design simplifies the device structure and improves the linkage between different functional mechanisms. The gas is blown out from the rear side wall of the inner groove 2, which can clean the upper surface of the transparent plate 302 during the discharge of the biscuit body 11, avoiding the residual biscuit residue from interfering with subsequent inspections and ensuring the inspection accuracy.

Many modifications and variations will be apparent to those of ordinary skill in the art.
