Description

Technical Field

[0001] The invention relates to the technical field of citrus deep processing auxiliary equipment, and in particular to a citrus cyst foreign body removal system. Background Art

[0002] Citrus cysts are made from citrus, and are finally obtained through peeling, segmenting, acid-base decysting, and dispersion. During these operations, it is inevitable that foreign matter or citrus peel and cyst residue will be mixed into the citrus cysts. Factories usually use manual observation and handheld suction cups to remove foreign matter, which is inefficient and cannot be removed completely. In order to improve the efficiency of foreign body removal, some existing technologies also use machine vision systems for removal. For example, Chinese patent application with publication number CN106000912A provides a citrus cyst foreign body removal system based on machine vision guidance, which includes a mechanical system, a visual measurement guidance system and a control system. The mechanical system includes a frame, a conveying device, and a removal device. The removal device includes a motion translation stage and a foreign body suction device arranged at the upper end of the motion translation stage. The foreign body suction device includes a suction nozzle, a vacuum generator and a retractable cylinder connected in sequence. The suction nozzle is also connected to the foreign body collection box through the vacuum generator. The visual measurement guidance system includes a light source, a camera group, and an image data acquisition card. The camera group includes a pre-processing camera arranged in the pre-detection area and a guiding camera arranged in the detection and removal area. The control system includes an industrial computer and a PLC. The control system controls the start of the conveying device, the light source and the camera group, the movement of the motion translation stage and the action of the foreign body suction device. Compared with manual detection, the invention is simple to operate, has a low missed detection rate, high efficiency and accuracy, and has great market value. However, the invention uses a suction nozzle to remove foreign matter. When the proportion of foreign matter is high, there may be a phenomenon of leakage. In order to reduce the probability of leakage, the overall speed needs to be reduced, resulting in relatively low overall efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a citrus cyst foreign body removal system, which solves the problem that the removal efficiency of foreign bodies in the prior art is still relatively low.

[0004] According to an embodiment of the present invention, a citrus cyst foreign body removal system includes a distribution tray, which is an umbrella-shaped structure and has a plurality of flow channels recessed on the umbrella surface, each flow channel is arranged obliquely and the lower end is connected to the bottom edge of the distribution tray and is provided with an outlet; a removal hole is provided on the inner bottom surface of the lower end of each flow channel, and a plurality of opening and closing parts that can open and close the single removal holes respectively are also provided in the umbrella-shaped structure of the distribution tray; and also includes an upper industrial camera, which includes a plurality of cameras arranged above the distribution tray and is used to photograph the plurality of flow channels on the distribution tray, and when the upper industrial camera photographs that there is foreign matter in one / multiple flow channels, the opening and closing parts of the corresponding flow channels are opened to allow the foreign matter to flow out through the removal holes.

[0005] In the above embodiment, the material (i.e., the citrus cysts to be processed) falls downward from the top of the distribution plate onto the distribution plate, then enters into each flow channel, slides downward along the flow channel, and is photographed by an industrial camera during the sliding process. When there is a foreign object in the flow channel and the foreign object slides above the rejection hole, the opening and closing member at the corresponding rejection hole opens, and the foreign object falls through the rejection hole. Then the opening and closing member closes, and normal material leaves the outlet smoothly. In this way, foreign objects in the material can be selected and removed faster and in a shorter time, without reducing the overall speed. Therefore, a higher rejection efficiency can be maintained, solving the problem that the rejection efficiency of foreign objects in the prior art is still relatively low.

[0006] Furthermore, the inner bottom surface of the flow channel is transparent, and multiple lower industrial cameras are arranged below the material distribution plate. When the upper industrial camera and / or the lower industrial camera captures foreign matter in one / multiple flow channels, the opening and closing parts of the corresponding flow channels are opened to allow the foreign matter to flow out through the removal holes.

[0007] Furthermore, a feed hopper is fixedly arranged above the material distribution tray, and the feed hopper has a discharge pipe located directly above the material distribution tray.

[0008] Furthermore, an umbrella-shaped rotating disk is buckled on the material distribution disk, the lower edge of the rotating disk covers the upper ends of all flow channels, and the top end extends upward into the discharge pipe.

[0009] Furthermore, a first annular groove and a second annular groove surrounding the first annular groove are fixedly arranged under the material distribution plate, the first annular groove is also fixedly connected to a discharge pipe, the second annular groove is also fixedly connected to a discharge groove, all rejection holes have an orthographic projection located in the first annular groove, and all outlets have an orthographic projection located in the second annular groove.

[0010] Furthermore, it also includes a mounting frame, which includes a bottom box and a support frame fixedly installed on the bottom box, the material distribution plate is located in the support frame, the feed hopper is fixedly connected to the upper end of the support frame, all upper industrial cameras are installed on the support frame, all lower industrial cameras are installed on the bottom box, the first ring groove and the second ring groove are installed on the bottom box, and the material distribution plate is fixedly connected to the bottom box.

[0011] Furthermore, a first driving motor is fixedly mounted on the bottom box. The first driving motor has a first rotating shaft extending upward, and the first rotating shaft is fixedly connected to the rotating disk.

[0012] Furthermore, the first annular groove is connected to a first water inlet pipe, and the second annular groove is also connected to a second water inlet pipe.

[0013] Furthermore, the opening and closing part includes a mounting base fixedly connected to the material distribution plate, a second drive motor installed on the mounting base, and a leakage plate connected to the second drive motor. The leakage plate is located below the rejection hole and a leakage hole is also provided on the leakage plate. During the operation of the second drive motor, the leakage hole can be opposite to or staggered with the rejection hole.

[0014] Furthermore, the opening and closing member includes a baffle, and a plurality of telescopic drivers for driving a baffle respectively are fixedly mounted on the material distribution plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The industrial camera is used to shoot the material situation in the flow channel. When there is foreign matter and the foreign matter slides above the rejection hole, the opening and closing part at the corresponding rejection hole opens, the foreign matter falls through the rejection hole, and then the opening and closing part closes, and normal materials leave smoothly from the outlet. In this way, foreign matter in the material can be selected and removed faster, and the time is shorter, thereby achieving efficient removal of foreign matter in citrus cysts and solving the problem that the removal efficiency of foreign matter in the prior art is still relatively low.

[0028] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] In an exemplary embodiment, Figure 1-9 As shown, the present embodiment provides a citrus cyst foreign body removal system, which includes a distribution tray 1, the distribution tray 1 is an umbrella-shaped structure and a plurality of flow channels 2 are recessed on the umbrella surface, each flow channel 2 is arranged obliquely and the lower end is connected to the bottom edge of the distribution tray 1 and is provided with an outlet 3; a removal hole 4 is provided on the inner bottom surface of the lower end of each flow channel 2, and a plurality of opening and closing parts that can open and close the single removal hole 4 respectively are also provided in the umbrella-shaped structure of the distribution tray 1; it also includes an upper industrial camera 6, the upper industrial camera 6 includes a plurality of cameras arranged above the distribution tray 1, which are used to photograph the plurality of flow channels 2 on the distribution tray 1, and when the upper industrial camera 6 photographs that there are foreign bodies in one / multiple flow channels 2, the opening and closing parts of the corresponding flow channels 2 are opened to allow the foreign bodies to flow out through the removal holes 4.

[0031] In the above embodiment, the material (i.e., the citrus cysts to be processed) falls downward from the upper part of the distribution plate 1 onto the distribution plate 1, then enters each flow channel 2, slides downward along the flow channel 2, and is photographed by the industrial camera 6 during the sliding process. When there is a foreign object in the flow channel 2 and the foreign object slides above the rejection hole 4, the opening and closing member at the corresponding rejection hole 4 is opened, and the foreign object falls through the rejection hole 4, and then the opening and closing member is closed, and the normal material smoothly leaves from the outlet 3, so that the foreign objects in the material can be selected and removed faster, which takes less time and does not require reducing the overall speed, so it can It can maintain a higher rejection efficiency, solving the problem that the rejection efficiency of foreign matter in the prior art is still relatively low; the various flow channels 2 arranged on the dividing plate 1 in this scheme can be equidistantly arranged around each other, and the dividing plate 1 with an umbrella-shaped structure makes the flow channel 2 inclined, so that the material can slide downward at a moderate speed in the flow channel 2. In a further scheme, the higher end of the flow channel 2 can be wider, so that the interval between the higher ends of each flow channel 2 is smaller, and the material can smoothly enter each flow channel 2 when falling on the dividing plate 1, instead of falling between the flow channels 2.

[0032] like Figure 1-9As shown, in a further exemplary embodiment, the system further includes a mounting frame, which includes a bottom box 7 and a support frame 8 fixedly mounted on the bottom box 7. The material distribution plate 1 is located in the support frame 8, and the material distribution plate 1 can be fixedly mounted on the bottom box 7 through a support column 9. A feed hopper 10 is also fixedly connected to the upper end of the support frame 8, and a discharge pipe 11 is fixedly connected to the lower end of the feed hopper 10. The discharge pipe 11 is located directly above the material distribution plate 1. During operation, materials are put into the feed hopper 10, and then fall onto the material distribution plate 1 through the discharge pipe 11, and the materials then enter each The foreign matter will go into the flow channel 2 and slide down in the flow channel 2. The flow channel 2 is wide at the top and narrow at the bottom, so the rejection hole 4 set at the lower position will not be too large (the rejection hole 4 can be square, with two sides against the two sides of the flow channel 2. The size of the foreign matter is generally smaller than the size of the normal material, and also smaller than the width of the flow channel 2 and the size of the rejection hole 4. In this way, the foreign matter will directly fall into the rejection hole 4 during the downward movement), avoiding the foreign matter from falling and carrying more normal materials with it, which will cause the materials to overlap more and more downward. If the foreign matter is located at the bottom of the material layer, it is not easy to be discovered by the upper industrial camera 6. Therefore, in this solution, a lower industrial camera 12 corresponding to the upper industrial camera 6 is also arranged below the material distribution tray 1. All upper industrial cameras 6 are installed on the support frame 8, and the tilted setting makes the lens of the upper industrial camera 6 aim at the multiple flow channels 2 obliquely below, and all lower industrial cameras 12 can be installed on the bottom box 7, and the corresponding tilted setting makes the lens of the upper industrial camera 6 aim at the multiple flow channels 2 obliquely above; in this solution, the inner bottom of the flow channel 2 can be transparent (the material distribution tray 1 in this solution The whole may also be transparent), so the lower industrial camera 12 can capture foreign matter in the flow channel 2. In more detail, the upper industrial camera 6 and the lower industrial camera 12 can also be multiple pairs corresponding to each other up and down, such as four pairs, which are respectively arranged on the four surfaces of the dividing plate 1, so that all the flow channels 2 on the dividing plate 1 are within the working range of the shooting. Specifically, when the upper industrial camera 6 and / or the lower industrial camera 12 captures foreign matter in one / more of the flow channels 2, the opening and closing parts of the corresponding flow channels 2 are opened to allow the foreign matter to flow out through the removal holes 4.

[0033] like Figure 1-9As shown, in a further exemplary embodiment, a first driving motor 20 located in the first annular groove 14 is also installed on the bottom box 7, and the first driving motor 20 has a first rotating shaft 21 extending upward, and the end of the first rotating shaft 21 is also connected to a rotating disk 22, and the rotating disk 22 is coaxially arranged with the material distribution disk 1 and covers the top of the material distribution disk 1, that is, the top of the material distribution disk 1 is provided with a through hole, and the first rotating shaft 21 is fixedly connected to the rotating disk 22 after passing through the through hole, and the top part of the rotating disk 22 extends into the lower end of the discharge pipe 11, so that the material in the feed hopper 10 Downward, then enters the discharge pipe 11, continues downward to contact the top of the rotating disk 22, and then is diffused to the surroundings by the rotating disk 22, and then transitions to the distribution disk 1 below along the disk surface of the rotating disk 22, and finally enters each flow channel 2. During the process, the first drive motor 20 can be operated to make the rotating disk 22 rotate between the distribution disk 1 and the feed hopper 10, so that the material on the rotating disk 22 can be subjected to a certain centrifugal effect, move in a downward rotating manner, and can be dispersed, so as to be more evenly distributed to each flow channel 2.

[0034] like Figure 1-9 As shown, in a further exemplary scheme, a first annular groove 14 located below the distributing plate 1 and a second annular groove 15 surrounding the first annular groove 14 are also installed on the bottom box 7, the first annular groove 14 is also fixedly connected to a discharge pipe 16, and the second annular groove 15 is also fixedly connected to a discharge trough 17, all the rejection holes 4 have an orthographic projection located in the first annular groove 14, and all the outlets 3 have an orthographic projection located in the second annular groove 15, and foreign matter falling through the rejection holes 4 falls into the first annular groove 14, while normal materials fall into the second annular groove 15, and are then respectively guided away by the discharge pipe 16 and the discharge trough 17; further, a first water inlet pipe 18 and a second water inlet pipe 19 for supplying water are respectively connected to the first annular groove 14 and the second annular groove 15, and the water introduced through them can make foreign matter and materials use water as a carrier and be guided away more smoothly. At the same time, the water introduced into the second annular groove 15 can also be an acid-base treatment liquid used for subsequent treatment, so that the material can directly enter the next process.

[0035] like Figure 1-7As shown, in a more detailed embodiment, the opening and closing member may include a mounting base fixedly connected to the material distribution disc 1, a second drive motor 24 mounted on the mounting base, and a leakage disc 25 connected to the second drive motor 24, the leakage disc 25 is located below the rejection hole 4 and a leakage hole 26 is also provided on the leakage disc 25, and the leakage hole 26 can be directly opposite or staggered with the rejection hole 4 during the operation of the second drive motor 24. More specifically, the mounting base can be an L-shaped structure located below the corresponding rejection hole 4, specifically including a vertical plate 27 fixedly connected to the material distribution disc 1 and a horizontal plate 28 fixedly connected to the vertical plate 27, the horizontal plate 28 is located directly below the rejection hole 4, the second drive motor 24 is mounted on the lower wall surface of the horizontal plate 28, the second drive motor 24 has a second rotating shaft 29 extending upward, and the second rotating shaft 29 is fixedly connected to the leakage disc 25 located above the horizontal plate 28. , and the leakage plate 25 set can be rotatably abutted with the distribution plate 1, and the second drive motor 24 is running to make the leakage plate 25 rotate relative to the distribution plate 1, so that the leakage hole 26 set on the leakage plate 25 can be opposite or staggered with the rejection hole 4. When opposite, the opening and closing part opens the rejection hole 4, and when staggered, the opening and closing part closes the rejection hole 4. In particular, the leakage holes 26 set on the leakage plate 25 can be a plurality of equidistant holes surrounding the second rotating shaft 29, and there is a large interval between adjacent holes to block the rejection hole 4, such as 4 equidistant leakage holes 26; in more detail, when the leakage hole 26 and the rejection hole 4 are opposite, their bottoms are open, that is, the rejection hole 4 has no vertical projection on the cross plate 28, which ensures that foreign matter will not be blocked by the cross plate 28 in the process of falling downward, and will fall smoothly into the first annular groove 14.

[0036] like Figure 1-5 As shown in Figures 8 and 9, in another more detailed embodiment, the opening and closing member can also be a baffle 5, and a baffle 5 can be driven by a single telescopic driver 13, specifically a telescopic cylinder, which is installed on the lower wall of the distribution plate 1, and the output end of the telescopic cylinder has a telescopic direction parallel to the flow channel 2 and the end is fixedly connected to the corresponding baffle 5. The baffle 5 can be moved to the bottom of the corresponding rejection hole 4 or moved away from the bottom of the rejection hole 4 by the operation of the telescopic cylinder, so as to realize the opening and closing of the rejection hole 4. In particular, the baffle 5 and the outer bottom surface of the corresponding flow channel 2 can be in sliding contact, so that the operation process is smoother; in particular, the upper industrial camera 6 and the lower industrial camera 12 in this scheme are also connected to a control system, which is similar to the visual measurement guidance system in the prior art as a whole, and is used to control the opening and closing of the opening and closing member.
