Abstract
Description
Technical Field
[0001] This utility model relates to the field of food sorting equipment technology, specifically a multi-functional sorting device. Background Technology
[0002] Bamboo shoots of different thicknesses are suitable for different processing techniques. Thinner bamboo shoots are suitable for processing into canned bamboo shoots, bamboo shoot shreds, and other foods, while thicker bamboo shoots are suitable for processing into dried bamboo shoots, bamboo shoot slices, and other foods. In addition, bamboo shoots of different lengths will also have different textures. Generally speaking, shorter bamboo shoots may have grown for a shorter period of time, and the shoots are tender and crisp. Longer bamboo shoots may have grown for a period of time, and the fibers will gradually increase, resulting in a relatively tougher texture. In order to meet the processing requirements of bamboo shoot products, bamboo shoots are usually sorted.
[0003] Currently used bamboo shoot sorting equipment mainly consists of conveyors based on machine vision measurement. During sorting, the conveyor belt on the conveyor transports the bamboo shoots past an industrial camera on the machine vision measurement box. The camera captures images of the bamboo shoots, and the algorithm automatically calculates the length of the bamboo shoots, making it convenient to sort the bamboo shoots based on their length. However, this type of sorting equipment has a single function and is not convenient for sorting bamboo shoots by measuring their thickness. In addition, the bamboo shoots transported to the industrial camera are sometimes arranged at an angle, which makes it impossible for the image processing algorithm to quickly calculate the length of the bamboo shoots by simply locating the two ends of the bamboo shoots. Utility Model Content
[0004] The purpose of this invention is to provide a multi-functional sorting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A multi-functional sorting device, comprising:
[0007] A conveyor, wherein a conveyor belt is driven to the top of the conveyor;
[0008] The coarseness measuring component includes two connecting rods that are rotatably connected to the conveyor, a rubber roller is rotatably connected between the two connecting rods, a motor capable of driving the rubber roller to rotate is fixed to the outside of one of the connecting rods, and a displacement sensor is also installed on the outside of the connecting rod.
[0009] Two adjusting components are respectively arranged below the corresponding connecting rods, and the adjusting components can adjust the height position of the rubber roller;
[0010] Two straightening components are fixedly connected to the conveyor. Each straightening component includes a cylinder, and a baffle is fixed to the output end of the cylinder.
[0011] The machine vision measurement box is fixedly connected to the conveyor and can collect images of bamboo shoots on the conveyor belt;
[0012] Multiple sorting components are evenly arranged on both sides of the conveyor. Each sorting component includes a second motor, and a sorting lever is fixed to the output end of the second motor.
[0013] Furthermore, an L-shaped plate is fixed to the top of one of the connecting rods, and both the motor and the displacement sensor are fixedly connected to the L-shaped plate.
[0014] Furthermore, the straightening component also includes a support plate fixedly connected to the cylinder, and the support plate is fixedly connected to the conveyor.
[0015] Furthermore, an industrial camera and a supplementary light are installed and fixed on the top of the machine vision measurement box, and two baffles are fixed at one end of the conveyor.
[0016] Furthermore, the sorting component also includes a material frame that is detachably and fixedly connected to the conveyor, the material frame being arranged on the outside of the sorting bar.
[0017] Furthermore, the adjusting component includes a sleeve, inside which a screw is screwed, and at the top of the screw is a support wheel that abuts against the connecting rod.
[0018] Furthermore, the bottom of the sleeve is fixed with a connecting seat that is fixedly connected to the conveyor, the top of the screw is rotatably connected with a support seat, and the support seat is rotatably connected to the support wheel.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. A connecting rod is rotatably connected to both sides of the conveyor, and a rubber roller is rotatably connected between the two connecting rods. Under the action of the adjusting component supporting the connecting rod, the rubber roller has a gap with the conveyor belt. A displacement sensor is installed on the top of one connecting rod. The user places the bamboo shoot with the tip facing the gap. As the conveyor belt conveys to the right and the motor drives the rubber roller to rotate counterclockwise, the bamboo shoot passes under the rubber roller. During the process of the bamboo shoot passing through the rubber roller, the rubber roller will cause the connecting rod to rotate to the upper right. The displacement sensor records the change in the height of the bamboo shoot before and after passing through the rubber roller. The larger the change in height, the thicker the bamboo shoot. This allows for the measurement of the thickness of the bamboo shoot, which is convenient for the subsequent sorting component to classify and store bamboo shoots of different thicknesses.
[0021] 2. By installing the displacement sensor at the same height as the rubber roller axis, the vertical displacement change value obtained by the displacement sensor after the bamboo shoot passes the rubber roller is the maximum diameter value of the bamboo shoot (because the diameters at both ends of the bamboo shoot are different), thereby achieving accurate measurement of the maximum diameter of the bamboo shoot. Based on the bamboo shoot diameter value measured by the thickness measuring device, the output ends of the two cylinders move the two baffles closer to the center, so that the distance between the two baffles is slightly larger than the bamboo shoot diameter value, so that the bamboo shoot is in a flat position before being conveyed to the machine vision measuring box. The bamboo shoot enters the machine vision measuring box in a posture parallel to the conveyor belt for the industrial camera to collect images.
[0022] When the length direction of the bamboo shoot is aligned with the scanning direction of the image, the length direction of the bamboo shoot in the image captured by the camera is consistent with the scanning direction of the image. This allows for more accurate detection of the two ends of the bamboo shoot, thereby reducing measurement errors and enabling the image processing algorithm to quickly calculate the length of the bamboo shoot simply by locating its two ends.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1, please refer to Figure 1 - Figure 4 In this embodiment of the invention, a multi-functional sorting device includes a conveyor 100. A conveyor belt 110 for conveying bamboo shoots is connected to the top of the conveyor 100. A thickness measuring component 200 for measuring the thickness of bamboo shoots is installed at one end of the conveyor 100. The thickness measuring component 200 includes two connecting rods 210, both rotatably connected to the outer side of the conveyor 100 housing. A rubber roller 220 is rotatably connected between the two connecting rods 210. A motor 230 for driving the rubber roller 220 is fixed to the outer side of one connecting rod 210. A displacement sensor 240 is also installed on the outer side of the connecting rod 210. The displacement sensor 240 can indirectly measure the thickness of the bamboo shoots by measuring the change in the height of the rubber roller 220. An adjusting component 300 for adjusting the height of the rubber roller 220 is provided below the connecting rod 210. The rod 210 is lifted upward to create a gap between the rubber roller 220 and the conveyor belt 110, facilitating the insertion of the bamboo shoot tip through the gap. Two straightening components 400 are fixedly connected to the top of the conveyor 100. Each straightening component 400 includes a cylinder 410. The output end of the cylinder 410 is fixed with a baffle 420 that can push the bamboo shoot straight in the center. A machine vision measuring box 500 is fixedly connected to the top of the conveyor 100. The machine vision measuring box 500 can collect images of the bamboo shoots on the conveyor belt 110 and then use an algorithm based on pixel pitch to calculate the length of the bamboo shoot by combining the outline information of the bamboo shoot. Multiple sorting components 600 are also installed and fixed at equal intervals on both sides of the conveyor 100. Each sorting component 600 includes a motor 610. The output end of the motor 610 is fixed with a dispensing rod 620, which can dispense bamboo shoots of different sizes to different directions.
[0030] Specifically, two connecting rods 210 are rotatably connected to one end of the conveyor 100, and a rubber roller 220 is rotatably connected between the two connecting rods 210. A displacement sensor 240 with the same height as the axis of the rubber roller 220 is fixed on the connecting rod 210. During the process of bamboo shoots being transported by the conveyor belt 110 to the bottom of the rubber roller 220 and passing through the rubber roller 220, the rubber roller 220 is lifted upward by the bamboo shoots, causing the connecting rods 210 to move upward with the displacement sensor 240 by a certain distance. The displacement sensor 240 records this upward distance as the diameter of the bamboo shoot, thereby realizing the pre-measurement of the thickness of the bamboo shoots before they enter the machine vision measuring box 500 to measure their length. Then, the straightening component 400 straightens the bamboo shoots and transports them into the machine vision measuring box 500 for length measurement, thereby realizing the automatic measurement of the length and thickness of the bamboo shoots, which facilitates the subsequent classification and storage of bamboo shoots of different specifications by multiple sorting components 600.
[0031] like Figure 3As shown, in this embodiment, the straightening component 400 also includes a support plate 430 fixedly connected to the cylinder 410. The support plate 430 is fixedly connected to the conveyor 100, thereby allowing the cylinder 410 to be installed on the outside of the conveyor 100. The distance that the output end of the cylinder 410 drives the second baffle 420 to move is determined by the maximum diameter of the bamboo shoot. After receiving the maximum diameter value of the bamboo shoot measured by the displacement sensor 240, the external control system controls the output ends of the two cylinders 410 to move a suitable distance simultaneously so that the distance between the two baffles 420 is sufficient for the bamboo shoot to pass straight through. The control principles related to the control system controlling the operation of the cylinder 410 and receiving the signal from the displacement sensor 240 are existing technologies and will not be described in detail here.
[0032] like Figure 3 As shown, in this embodiment, an L-shaped plate is fixed to the top of a connecting rod 210. The motor 230 and the displacement sensor 240 are both fixedly connected to the L-shaped plate, so that the motor 230 and the displacement sensor 240 are both mounted on the connecting rod 210. When the conveyor belt 110 conveys bamboo shoots, the motor 230 drives the rubber roller 220 to rotate synchronously, which helps the bamboo shoots to pass smoothly between the rubber roller 220 and the conveyor belt 110. The installation height of the displacement sensor 240 is the same as the axial position of the rubber roller 220, so that the displacement value measured by the displacement sensor 240 is the diameter value of the bamboo shoot.
[0033] In this embodiment, two baffles 120 are fixed at one end of the conveyor 100. The baffles 120 prevent the bamboo shoots from leaving the conveyor belt 110 during the bamboo shoot feeding process. Specifically, the bamboo shoots are fed with their tips facing the rubber roller 220.
[0034] like Figure 1 As shown, in this embodiment, an industrial camera and a supplementary light are installed and fixed on the top of the machine vision measurement box 500. The machine vision measurement box 500, the industrial camera and other related structures use existing technology. The working principle of measuring the length by acquiring bamboo shoot images will not be described in detail.
[0035] like Figure 1 and Figure 2As shown, in this embodiment, the sorting component 600 also includes a material frame 630 detachably and fixedly connected to the conveyor 100. The material frame 630 is arranged on the outside of the sorting rod 620. The material frames 630 at different positions can hold bamboo shoots of different specifications. Before the bamboo shoots that meet the specifications move to the position of the sorting rod 620, the motor 610 drives the sorting rod 620 to rotate and unfold in the direction of the conveyor belt 110. After the bamboo shoots move to the inside of the sorting rod 620, the motor 610 drives the sorting rod 620 to rotate in the opposite direction, pushing the bamboo shoots into the material frame 630, thereby realizing the sorting of bamboo shoots of different specifications. The specific dimensions of the material frames 630 holding bamboo shoots of different lengths or thicknesses can be set according to the actual processing needs, which will not be elaborated here. In addition, different numbers of sorting components 600 can be installed as needed. The illustration of this utility model only shows the case of installing four sorting components 600.
[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the adjusting component 300 includes a sleeve 310, a screw 320 is screwed into the sleeve 310, a nut 321 is fixed to the outside of the screw 320, a support wheel 330 is provided at the top of the screw 320 and abuts against the connecting rod 210, a connecting seat 350 is fixed at the bottom of the sleeve 310 and is fixedly connected to the conveyor 100, and a support seat 340 is rotatably connected to the top of the screw 320, and the support seat 340 is rotatably connected to the support wheel 330.
[0037] In this embodiment, different types of bamboo shoots are generally of different thicknesses. When it is necessary to pass thicker bamboo shoots such as moso bamboo through the rubber roller 220, the nut 321 can be rotated in advance to move the screw 320 out of the sleeve 310. The screw 320 moves the support wheel 330 on the support seat 340 upward, which in turn moves the connecting rod 210 upward along with the rubber roller 220. This ensures that the gap between the rubber roller 220 and the conveyor belt 110 is large enough to allow the tip of the thicker moso bamboo to be manually inserted a certain distance, preventing damage to the tip of the bamboo shoot due to a small gap between the rubber roller 220 and the conveyor belt 110.
[0038] In this utility model, both the conveyor 100 and the conveyor belt 110 are existing technology equipment, and the specific conveying principle will not be described in detail.
[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
