Description

Technical Field

[0001] The present invention relates to the technical field of food sorting, and in particular to a food sorting device based on visual detection. Background Art

[0002] In the field of food processing and sales, traditional sorting methods mainly rely on manual labor. For example, in the sorting of fruits and vegetables, maturity, fruit diameter, surface defects, etc. are manually identified. The accuracy of manual sorting is difficult to guarantee and is easily affected by factors such as workers' identification ability and emotions, resulting in deviations in grading standards. Especially for small fruits and vegetables, the grading error is large. In addition, for some foods with complex appearance characteristics, such as tomatoes with large size, color difference and defect diversity, traditional methods are difficult to accurately identify and classify.

[0003] The China Patent Network has published a patent application with the number CN106238342A, which discloses a panoramic visual potato sorting and defect detection device, including a conveying device, a detection dark box, a sorting mechanism, an infrared sensor module, and an image acquisition mechanism. The device mainly uses the detection dark box and the infrared sensor module to visually sort potatoes.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0036] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0037] Example

[0038] Reference Figure 1 - Figure 7 , which is the first embodiment of the present invention, provides a food sorting device based on visual inspection, including a conveyor belt 1, a visual unit 11 is installed above the conveyor belt 11, and a sorting component 12 is installed on one side of the conveyor belt 1. The conveyor belt 1 conveys fruits through the visual unit 11, and the visual unit 11 system controls the sorting component 12 to operate, thereby sorting the fruits by controlling the sorting component 12.

[0039] The top of the slanted plate 231 is provided with a pressure arc block 242, and the inner wall of the slanted plate 231 is provided with a pressure bump 241, which is connected to the pressure arc block 242 on the inner wall of the slanted plate 231.

[0040] Its collecting hopper 21 is used for stacking fruits, and the fruits naturally fall into the arrangement groove 22 for discharge. When the conveyor belt 1 is running, the contact and pressure protrusion 321 is driven by the transmission mechanism to reciprocate and press the compressed arc block 242. Each contact and pressure will drive the positioning baffle 24 and the bending baffle 232 to deflect and move, and each deflection movement of the bending baffle 232 will press the unlocking plate 227 and the locking rod 225, so that the cross arrangement frame 222 can be unlocked. At this time, relying on the inclined state of the arrangement groove 22, the fruit naturally pushes the cross arrangement frame 222, so that the cross arrangement frame 222 rotates and drops a single fruit from the inclined plate 231 and the bending baffle 232. When the positioning baffle 24 deflects and moves, the previous fruit that fell and moved to the side of the positioning baffle 24 and was then restricted from moving will be released, so that the interval between fruits discharged each time is the same.

[0041] Furthermore, a support spring 243 is installed on the outer wall of one side of the compressed arc block 242, and the other end of the support spring 243 is connected to the inner wall of the arrangement positioning box 2. The support spring 243 maintains the positioning baffle 24 in a vertical state when the compressed arc block 242 is not compressed. The connecting plate 241 and the bending baffle 232 are connected by a movable connecting rod 244, so that when the compressed arc block 242 is compressed, the connection end of the bending baffle 232 and the movable connecting rod 244 is pulled downward, and at this time the other end of the bending baffle 232 moves toward the side of the inclined plate 231.

[0042] Furthermore, a through groove 221 is provided on the inner bottom wall of the arrangement groove 22, and the through groove 221 provides installation space for the cross arrangement frame 222 in the area below the arrangement groove 22, and the arrangement groove 22 is in an inclined state, so that the unloaded fruits have a thrust on the cross arrangement frame 222, and a disc 223 is installed on the outer wall of one side of the cross arrangement frame 222, and four groups of locking grooves 224 are evenly provided on the disc 223, and the locking grooves 224 are used to be embedded and locked in the locking rod 225 movably connected to the inner wall of the arrangement and positioning box 2 through a pin shaft.

[0043] Furthermore, a fixing plate 226 is installed on the bottom side of the inclined plate 231, and the fixing plate 226 is used to movably connect the middle area of ​​the unlocking plate 227, so that when one end of the unlocking plate 227 is pressed and moves upward, the other end of the unlocking plate 227 can press the locking rod 225 downward. A fixing spring 228 is installed on the top of the unlocking plate 227, and the other end of the fixing spring 228 is connected to the bottom of the inclined plate 231. The fixing spring 228 pulls the unlocking plate 227, so that the locking rod 225 at one end of the unlocking plate 227 locks the locking groove 224 of the disc 223.

[0044] Furthermore, the driving wheel 3 and the driven wheel 31 are connected via a belt, and the first gear 311 and the second gear 32 are in meshing state. The transmission efficiency of the conveyor belt 1 and the contact and pressure bump 321 can be set according to the gear ratio of the first gear 311 and the second gear 32.

[0045] Furthermore, a second gear 32 is mounted on the inner wall of the alignment and positioning box 2 via a shaft, and the other end of the shaft connected to the second gear 32 is connected to the contact and pressure protrusion 321 .

[0046] Furthermore, the driving wheel 3 and the driven wheel 31 are connected to each other through a belt, and the first gear 311 and the second gear 32 are in meshing state.

[0047] Furthermore, a rotating ring 211 is installed on the inner bottom wall of the collecting hopper 21 , an inclined block 212 is installed on the inner wall of the rotating ring 211 , and a tooth groove 213 is formed on the outer wall of the rotating ring 211 .

[0048] Furthermore, a transmission assembly 4 is installed in the arrangement and positioning box 2, and the transmission assembly 4 includes a first conical tooth 41 installed on the disc 223, and the conical tooth is engaged with a conical tooth transmission rod 42. One end of the conical tooth transmission rod 42 is transmission-installed with a second conical tooth 43, and the top of the second conical tooth 43 is connected to a transmission tooth 44 through a shaft, and the transmission tooth 44 is engaged with the tooth groove 213. The conical tooth transmission rod 42 is composed of two groups of conical teeth and a rod body, so that the first conical tooth 41 can drive the second conical tooth 43 to rotate.

[0049] Working principle: When sorting food, the transmission wheel 3 is driven by the conveyor belt 1, the transmission wheel 3 drives the driven wheel 31 to rotate, the driven wheel 31 rotates and drives the first gear 311 to rotate, the first gear 311 drives the second gear 32 to rotate, and the second gear 32 drives the contact and pressure protrusion 321 to rotate, so that the contact and pressure protrusion 321 cyclically contacts and presses the compressed arc block 242, and the fruits are stacked in the inclined arrangement groove 22. When the contact and pressure protrusion 321 contacts and presses the compressed arc block 242, the bending baffle 232 moves toward the inclined plate 231 side moves, its bent baffle 232 contacts the unlocking plate 227, the unlocking plate 227 rotates with the fixed point of the fixed plate 226 as the rotation point, so that the unlocking plate 227 rotates and contacts the locking rod 225, so that the locking rod 225 moves down and separates from the locking groove 224. At this time, the disc 223 is not locked, and its arrangement groove 22 has a certain slope, so that the fruit has a tendency to move to the side of the inclined plate 231. When the disc 223 is unlocked, the fruit triggers the cross arrangement frame 222 to rotate, and the fruit begins to The inclined plate 231 and the bent baffle 232 are reopened, and the positioning baffle 24 is now in a vertical blocking state, so that the fruit above the cross-arrangement rack 222 falls onto the conveyor belt 1 from the opening of the inclined plate 231 and the bent baffle 232, so that the conveyor belt 1 moves the fruit to the side of the positioning baffle 24 and is restricted from moving until the next time the convex part of the contact block 321 rotates to contact the compressed arc block 242, and the compressed slider presses down the connecting plate 2 41 side, so that the positioning baffle 24 on the other side of the connecting plate 241 rotates open, at this time the positioning baffle 24 can release the fruit, and when the fruit on one side of the positioning baffle 24 is released, the bent baffle 232 and the inclined plate 231 are closed again, and a new fruit falls in again, and when the compressed arc block 242 is not compressed, the fruit falls back onto the conveyor belt 1, and this reciprocating cycle makes it possible for each released fruit to be positioned, so that the interval between each fruit is consistent, and the fruit interval maintains the optimal distance;

[0050] Each rotation of the disc 223 causes the rotating ring 211 to rotate slightly through the transmission of the first conical teeth 41, the conical gear transmission rod 42 and the second conical teeth 43, so that the slightly rotating rotating ring 211 and the inclined block 212 break the static balance that may exist in the collecting hopper 21 (that is, the fruits are stuck at the connection between the arrangement groove 22 and the collecting hopper 21), thereby allowing the fruits to be smoothly sorted individually in the arrangement groove 22.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
