Description

Technical Field

[0001] The invention relates to the field of strip product processing equipment, and in particular to a clamping and conveying device and screening equipment for strip products that do not deform or break. Background Art

[0002] During the production process of strip products such as chopsticks, due to their slender structure, in order to transport them smoothly, the strip products are usually placed horizontally on the conveying device. The existing conveying device for strip products, as described in the patent document of Chinese Patent Application No. 201920837686.8, generally includes a conveyor belt, and the conveyor belt is provided with a groove. During transportation, the strip products correspond one-to-one to the groove on the conveyor belt, and are horizontally limited in the groove on the conveyor belt, and are driven by the conveyor belt for transportation. As a link in the production process, the conveying device needs to correspond to the requirements of each process, and the same conveying device may not be suitable for all processes in the production process. The above-mentioned strip product conveying device is also the same. During its transportation process, after the strip product is limited in the groove on the conveyor belt, part of the structure of the strip product is blocked, and for some other reasons, it cannot be used in processes that require observation of the entire appearance of the strip product.

[0003] Moreover, after the strip products are processed and formed, their quality often needs to be tested, and the strip products that are not deformed or broken need to be screened according to their quality, such as screening into fine products, qualified products, defective products, etc., or different strip products of different colors need to be distinguished. The traditional screening method for strip products mainly adopts manual visual observation and manual screening; this screening method is not only easy to cause visual fatigue of the staff, but also has high labor intensity, slow screening speed, low work efficiency, and large errors in naked eye screening. The screening results of each staff member are also different, and the screening accuracy is low. Summary of the invention

[0004] The first object of the present invention is to provide a device for clamping and conveying strip products without deformation or breakage.

[0005] The technical solution to achieve the purpose of the present invention is: a clamping and conveying device for non-deformed and non-broken strip products, comprising a first conveying mechanism, on which a plurality of clamping mechanisms are arranged, the clamping mechanisms comprising a first side clamping portion and a second side clamping portion arranged along the width direction of the first conveying mechanism; the first side clamping portion comprises a first mounting seat and a first side clamp, the first mounting seat is fixedly mounted on the first conveying mechanism, and the first side clamp is mounted on the first mounting seat;

[0006] The second side clamping portion comprises a second mounting seat, a compression spring and a sliding assembly, the second mounting seat is fixedly mounted on the first conveying mechanism, a slide rail is transversely arranged on the second mounting seat, the sliding assembly comprises a slide seat, a second side clamp and a guide member, the slide seat is slidably mounted on the slide rail, the second side clamp and the guide member are both fixedly mounted on the slide seat, the second side clamp is opposite to the first side clamp of the first side clamping portion, the compression spring is horizontally arranged, one end of the compression spring close to the first side clamping portion contacts the sliding assembly, and one end of the compression spring away from the first side clamping portion contacts the second mounting seat;

[0007] An input station and an output station are provided on the strip product conveying path of the first conveying mechanism, and a cam block is provided on each of the input station and the output station. The cam block is fixedly mounted on a frame, and a guide rail is provided on the cam block. The guide rail is located on the conveying path of the guide member, and the guide rail is a curved surface convex toward the side away from the first side clamping portion.

[0008] Further, the first side clamp has a first clamping groove, the second side clamp has a second clamping groove, and the notch of the first clamping groove is opposite to the notch of the second clamping groove. When the first side clamp and the second side clamp clamp the strip-shaped product, the two ends of the strip-shaped product are respectively located in the first clamping groove of the first side clamp and the second clamping groove of the second side clamp, and the first clamping groove and the second clamping groove can limit the two ends of the strip-shaped product, so that the first side clamp and the second side clamp can be more stable when clamping the strip-shaped product for conveying.

[0009] Furthermore, a first guide rod parallel to the compression spring is fixedly mounted on the second mounting seat, and a second guide rod is fixedly mounted on the slide seat. The second guide rod is coaxial with the first guide rod and spaced apart, and the distance between the second guide rod and the first guide rod is greater than the width of the guide track protruding away from the first side clamping portion; one end of the compression spring away from the first side clamping portion is sleeved on the first guide rod, and one end of the compression spring close to the first side clamping portion is sleeved on the second guide rod. The first guide rod and the second guide rod are arranged to limit the two ends of the compression spring and guide the deformation of the compression spring so that the compression spring will not bend. Wherein, the distance between the second guide rod and the first guide rod is greater than the width of the guide track protruding away from the first side clamping portion, and its function is to ensure that the guide member moves the slide seat under the action of the cam block, and the deformation of the compression spring allows the guide member to pass through the cam block smoothly.

[0010] Furthermore, the guide member is a guide wheel vertically arranged with the central axis. The guide member can be a rod body, or a guide wheel or a bearing, etc. Compared with other guide wheels, the guide wheel is easier to install, and when the guide member moves along the guide track, there is rolling friction between the rolling guide wheel and the guide track, and the friction force is small, so the guide member and the guide track are not easy to wear.

[0011] Furthermore, the first conveying mechanism includes two conveying devices arranged horizontally, the first side clamping part and the second side clamping part are respectively arranged on the two conveying devices; two guide rods are horizontally arranged on the frame, at least one of the two conveying devices is slidably mounted on the two guide rods of the frame, and the frame is also penetrated by an adjusting screw matched with the thread of the frame, the adjusting screw is parallel to the guide rod, the adjusting screw corresponds to the conveying device slidably mounted on the guide rod, and the adjusting screw is rotatably connected and fixed to the corresponding conveying device. The first conveying mechanism can be composed of one conveying device, or it can be composed of two arranged conveying devices. Since the length of the strip product is relatively long, when the strip product is clamped by both ends of the strip product to convey the strip product, the width requirement of the first conveying mechanism is also relatively large. When the first conveying mechanism is composed of two arranged conveying devices, on the one hand, its structure is simple, and the requirement of a larger width of the first conveying mechanism can be met by setting the positions of the two conveying devices; on the other hand, after the first conveying mechanism is composed of two arranged conveying devices, the width of the first conveying mechanism can be adjusted by adjusting the positions of the two conveying devices, thereby making the setting of the first conveying mechanism more flexible. Under the above setting of the present invention, at least one of the two conveying devices is slidably installed on the two guide rods of the frame, and the adjusting screw is rotated to drive the corresponding conveying device, so that the corresponding conveying device moves along the guide rod, and then the width of the first conveying mechanism can be adjusted, so that the first conveying mechanism can be applied to the clamping and conveying of strip products of different sizes.

[0012] The clamping and conveying device for non-deformed and non-breakage strip products of the present invention can automatically clamp the strip products under the action of the cam blocks through the clamping mechanism on the first conveying mechanism and the cam blocks at the input station and the output station. After being clamped, the strip products can be conveyed by the first conveying mechanism. After being conveyed to the right place, the strip products can be automatically released under the action of the cam blocks. The whole process of conveying the strip products has a high degree of automation and is convenient to use. When the clamping mechanism on the first conveying mechanism clamps the strip products for conveying, it clamps the strip products at both ends. During the conveying process, the whole circumferential part of the strip products is unobstructed. The device is suitable for processes where the whole appearance of the strip products needs to be observed, such as the process of screening strip products.

[0013] The second object of the present invention is to provide a screening device for strip products that does not deform or break.

[0014] A screening device for non-deformed and non-breakage strip products, comprising a conveying device, wherein the conveying device comprises the clamping conveying device and the lying conveying device described in the present invention, the clamping conveying device is connected to the strip product conveying path on the lying conveying device; the lying conveying device comprises a second conveying mechanism, on which a plurality of strip product placement slots are horizontally arranged, and both ends of the strip product placement slots are open; in the clamping conveying device, a body imaging camera is vertically arranged laterally on the first conveying mechanism for acquiring body surface image data of the strip product except for the two ends, and an end imaging camera is horizontally arranged on both sides of the second conveying mechanism for acquiring surface image data of the corresponding side ends of the strip product. The screening equipment for non-deformed and non-break strip products of the present invention conveys the strip products in different states front and back through the clamping conveying device and the lying conveying device, so that different parts of the strip products can be exposed during two different conveying processes. At the same time, the body imaging camera and the end imaging camera are equipped to photograph different parts of the strip products conveyed by the clamping conveying device and the lying conveying device in batches, so that complete surface image data of the strip products can be finally obtained. The surface image data of the strip products is more complete and integrated, and the accuracy of grading is also higher.

[0015] Furthermore, the conveying device also includes an inclined conveying device, the clamping conveying device, the lying conveying device and the strip product conveying path on the inclined conveying device are connected end to end, and the clamping conveying device and the lying conveying device are both located on the side of the inclined conveying device close to the input end of the conveying device; the inclined conveying device includes an inclined conveying mechanism arranged obliquely, and a strip product placement groove is horizontally provided on the inclined conveying mechanism, and more than one group of air nozzles are provided on the lower side of the strip product conveying path on the inclined conveying mechanism, and the air nozzles are facing the strip product conveying path on the inclined conveying mechanism. The present invention provides a screening device for non-deformed and non-fractured strip products. The inclined conveying device is arranged on the side of the clamping conveying device and the lying conveying device close to the output end of the conveying device, and one or more air nozzles are arranged on the lower side of the conveying path of the strip products on the inclined conveying mechanism, so that in the process of the conveying device conveying the strip products, the strip products can be photographed by the body imaging camera and the end imaging camera to obtain image data of the surface of the strip products. According to the image data of the strip products, the quality of the strip products is graded or different colors are judged, and then the strip products of different grades or colors are distinguished by the air nozzle to achieve the screening of strip products of different qualities or colors. The present invention provides a screening device for non-deformed and non-fractured strip products. The body imaging camera, the end imaging camera and the air nozzle can all be intelligently controlled. Under the control of the control system, it is easy to form a set of fully automated screening devices. The screening device not only has high working efficiency and fast detection speed, but also its intelligent detection and screening no longer rely on human eyes, the labor intensity is greatly reduced, and the accuracy of the screening results is also greatly improved.

[0016] Furthermore, each group of the air nozzles is provided with a corresponding collection box, and the collection box is located on the air path of the corresponding air nozzle. After the air nozzles blow the strip products of different colors or corresponding grades out of the inclined conveying mechanism, the strip products fall into the corresponding collection box for collection.

[0017] Further, the clamping conveying device, the lying conveying device and the inclined conveying device are sequentially distributed along the conveying direction of the conveying device, wherein the second conveying mechanism and the inclined conveying mechanism are integrally formed.

The clamping conveying device is located at the side of the lying conveying device close to the conveying end of the conveying device, and the clamping conveying device, the lying conveying device and the inclined conveying device are sequentially distributed along the conveying direction of the conveying device. Since the second conveying mechanism has a slot for placing strip products, and the inclined conveying mechanism has a slot for placing strip products, the structures of the lying conveying device and the inclined conveying device are basically the same, so the second conveying mechanism and the inclined conveying mechanism can be integrally formed, consisting of the same conveying device, so that the setting is more convenient.

During operation, the strip-shaped products are placed in the feeding bin, and since the input end of the feeding conveying mechanism is located in the feeding bin, the strip-shaped products in the feeding bin will enter the material feed slot on the feeding conveying mechanism, and will be transported by the feeding conveying mechanism to the input station of the clamping conveying device. Under this setting, automatic feeding can be realized, making feeding more convenient and the degree of automation of the equipment higher.

[0019] The screening equipment for strip products which does not deform or break of the present invention is provided by arranging the inclined conveying device on the side of the clamping conveying device and the lying conveying device close to the output end of the conveying device, and arranging one or more air nozzles on the lower side of the conveying path of the strip products on the inclined conveying mechanism, so that in the process of the conveying device conveying the strip products, the strip products can be photographed by the body imaging camera and the end imaging camera to obtain image data of the surface of the strip products, and the quality of the strip products can be graded or different colors can be judged according to the image data of the strip products, and then the strip products of different grades or colors can be distinguished by the air nozzles to achieve screening of strip products of different qualities or colors.

[0036] The following is a detailed description of the preferred embodiments of the clamping and conveying device and screening device for the strip-shaped products that do not deform or break according to the present invention in conjunction with the accompanying drawings:

[0037] like Figures 1 to 9 As shown, a clamping and conveying device for a strip product that does not deform or break comprises a first conveying mechanism 1, on which a plurality of clamping mechanisms 2 are arranged, wherein the clamping mechanisms 2 comprise a first side clamping portion 21 and a second side clamping portion 22 arranged along the width direction of the first conveying mechanism 1; the first side clamping portion 21 comprises a first mounting seat 211 and a first side clamp 212, wherein the first mounting seat 211 is fixedly mounted on the first conveying mechanism 1, and the first side clamp 212 is mounted on the first mounting seat 211;

[0038] The second side clamping portion 22 includes a second mounting seat 221, a compression spring 222 and a sliding assembly 220. The second mounting seat 221 is fixedly mounted on the first conveying mechanism 1. A slide rail 2211 is transversely arranged on the second mounting seat 221. The sliding assembly 220 includes a slide seat 223, a second side clamp 224 and a guide member 225. The slide seat 223 is slidably mounted on the slide rail 2211. The second side clamp 224 and the guide member 225 are both fixedly mounted on the slide seat 223. The second side clamp 224 is opposite to the first side clamp 212 of the first side clamping portion 21. The compression spring 222 is horizontally arranged. One end of the compression spring 222 close to the first side clamping portion 21 contacts the sliding assembly 220, and one end of the compression spring 222 away from the first side clamping portion 21 contacts the second mounting seat 221.

[0039] An input station 101 and an output station 102 are provided on the strip product conveying path on the first conveying mechanism 1, and a cam block 3 is provided on each of the input station 101 and the output station 102. The cam block 3 is fixedly mounted on a frame 1000, and a guide rail 31 is provided on the cam block 3. The guide rail 31 is located on the conveying path of the guide member 225, and the guide rail 31 is a curved surface convex toward the side away from the first side clamping portion 21.

[0040] The present invention is a clamping and conveying device for non-deformable and non-breakage strip products. The first conveying mechanism 1 is provided with a plurality of clamping mechanisms 2. Each of the clamping mechanisms 2 includes a first side clamping portion 21 and a second side clamping portion 22. The first side clamp 212 of the first side clamping portion 21 is opposite to the second side clamp 224 of the second side clamping portion 22, and is respectively used to support the strip products 2000 at both ends so that the strip products are clamped, and then the strip products 2000 can be conveyed together with the first conveying mechanism 1.

[0041] The present invention is a clamping and conveying device for non-deformable and non-breakage strip products. In each of the clamping mechanisms 2, the slide 223 of the second side clamping portion 22 is slidably installed on the slide rail 2211. The slide 223 of the second side clamping portion 22 can not only be conveyed together with the first conveying mechanism 1, but also can slide laterally along the slide rail 2211. Specifically, since the compression spring 222 is arranged between the second mounting seat 221 and the slide seat 223, the end of the compression spring 222 close to the first side clamping portion 21 contacts the sliding assembly 220, and the end of the compression spring 222 away from the first side clamping portion 21 contacts the second mounting seat 221. Under the action of the compression spring 222, the slide seat 223 and the second side clamp 224 and the guide member 225 thereon are always pushed toward the side close to the first side clamping portion 21, and the distance between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 is relatively small; the input station 101 and the output station 1 At 02, the guide member 225 of the second side clamping portion 22 passes through the guide track 31 of the cam block 3. Since the guide track 31 is a curved surface convex toward the side away from the first side clamping portion 21, when the guide member 225 passes through the guide track 31, it is guided by the guide track 31 toward the side away from the first side clamping portion 21, and the compression spring 222 is further compressed. The guide member 225 and the second side clamp 224 move together with the slide seat 223 along the slide rail 2211 toward the side away from the first side clamp 21, and the distance between the first side clamp 212 of the first side clamp 21 and the second side clamp 224 of the second side clamp 22 becomes larger.

[0042] The clamping and conveying device for the strip-shaped product of the present invention does not deform or break. When conveying the strip-shaped product 2000, the clamping mechanism 2 on the first conveying mechanism 1 is conveyed together with the first conveying mechanism 1. When the clamping mechanism 2 is conveyed to the input station 101, the guide member 225 of the second side clamping portion 22 passes through the guide track 31 of the cam block 3. Under the guidance of the guide track 31, the guide member 225 and the second side clamp 224 move along the slide rail 22 together with the slide seat 223. 11 moves toward the side away from the first side clamping portion 21, and the distance between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 becomes larger; after the distance between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 becomes larger, the strip product 2000 to be transported can be placed horizontally between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22. After the clamping mechanism 2 has completely passed the input station 101 along with the first conveying mechanism 1, the guide member 225 is no longer guided by the guide rail 31, and the slide seat 223 and the second side clamp 224 thereon are pushed toward the side close to the first side clamping portion 21 under the action of the compression spring 222, and the distance between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 becomes smaller, thereby clamping the strip product to be conveyed from both ends, so that the strip product can be conveyed together with the first conveying mechanism 1. After the strip product is conveyed to the output station 102, the guide member 225 of the second side clamping portion 22 passes through the guide track 31 of the cam block 3. Under the guidance of the guide track 31, the guide member 225 and the second side clamp 224 move together with the slide seat 223 along the slide rail 2211 to the side away from the first side clamping portion 21. The distance between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 becomes larger, and the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 loosen the strip product therebetween. In this way, the strip product 2000 can be output from the first conveying mechanism 1.

[0043] The clamping and conveying device for non-deformed and non-breakage strip products of the present invention is provided with a clamping mechanism 2 on the first conveying mechanism 1. At the same time, when the second side clamp 224 of the second side clamping portion 22 of the clamping mechanism 2 is conveyed to the input station 101 and the output station 102, the guide member 225 is guided by the cam block 3 installed at the input station 101 and the output station 102, and the second side clamp 224 can move to the side away from the first side clamping portion 21, and the distance between the first side clamp 212 of the first side clamping portion 21 and the second side clamp 224 of the second side clamping portion 22 can be increased to clamp the strip product to be conveyed, or release the strip product conveyed to the position, thereby completing the entire clamping and conveying action, so that the clamping mechanism 2 can clamp the strip product from both ends of the strip product to convey the strip product.

[0044] The clamping and conveying device for non-deformed and non-breakage strip products of the present invention, through the clamping mechanism 2 on the first conveying mechanism 1, and the cam blocks 3 at the input station 101 and the output station 102, enables the clamping mechanism 2 to automatically clamp the strip product 2000 under the action of the cam block 3, and the strip product 2000 can be automatically conveyed by the first conveying mechanism 1 after being clamped, and after being conveyed to the right place, the strip product is automatically released under the action of the cam block 3, and the whole process of conveying the strip product has a high degree of automation and is convenient to use; and when the clamping mechanism 2 on the first conveying mechanism 1 clamps the strip product for conveying, it clamps the strip product at both ends, and the whole circumferential part of the strip product is unobstructed during the conveying process, and is suitable for processes that require observation of the entire appearance of the strip product, such as the screening process of the strip product.

When the first side clamp 212 and the second side clamp 224 clamp the strip-shaped product, the two ends of the strip-shaped product are respectively located in the first clamping groove 2121 of the first side clamp 212 and the second clamping groove 2241 of the second side clamp 224, and the first clamping groove 2121 and the second clamping groove 2241 can limit the two ends of the strip-shaped product, so that the first side clamp 212 and the second side clamp 224 can be more stable when clamping the strip-shaped product for conveying.

[0046] In the clamping and conveying device for the strip product without deformation or breakage of the present invention, preferably, the first clamping groove 2121 and the second clamping groove 2241 are both tapered grooves. Under this structure, the first clamping groove 2121 and the second clamping groove 2241 are both expanded grooves, and when the expanded grooves clamp the two ends of the strip product, the ends of the strip product can more easily enter the first clamping groove 2121 and the second clamping groove 2241.

[0047] In the clamping and conveying device for the strip-shaped product of the present invention that does not deform or break, preferably, the slide rail 2211 is parallel to the width direction of the first conveying mechanism 1. The slide rail 2211 can be parallel to the width direction of the first conveying mechanism 1, or can be slightly inclined to the width direction of the first conveying mechanism 1. Since the first side clamping portion 21 and the second side clamping portion 22 are arranged transversely along the width direction of the first conveying mechanism 1, and in order to make the spacing between the first side clamping portion 21 and the second side clamping portion 22 directly and efficiently adjustable at the input station 101 and the output station 102, preferably, the slide rail 2211 is completely parallel to the width direction of the first conveying mechanism 1.

[0048] In the clamping and conveying device for strip products that does not deform or break of the present invention, preferably, the compression spring 222 is parallel to the slide rail 2211. When the slide seat 223 moves along the slide rail 2211 under the action of the cam block 3 or the compression spring 222, the compression spring 222 will also deform. During the deformation of the compression spring 222, in order to reduce the force in other directions, the structure of the compression spring 222 is destroyed, so that the compression spring 222 is bent. Preferably, the compression spring 222 is parallel to the slide rail 2211.

The provision of the first guide rod 2261 and the second guide rod 2262 is used to limit the two ends of the compression spring 222 and guide the deformation of the compression spring 222 so that the compression spring 222 will not bend. Among them, the distance L1 between the second guide rod 2262 and the first guide rod 2261 is greater than the width L2 of the guide rail 31 protruding away from the first side clamping portion 21, and its function is to ensure that the guide member 225 moves the slide seat 223 under the action of the cam block 3, and the deformation of the compression spring 222 allows the guide member 225 to pass through the cam block 3 smoothly.

[0050] In the clamping and conveying device for the strip-shaped product that does not deform or break of the present invention, the end of the compression spring 222 close to the first side clamping portion 21 can contact any one of the slide seat 223, the second side clamp 224 and the guide member 225 in the sliding assembly 220.

When the strip product is clamped at the input station 101 or the strip product is released at the output station 102, only the second side clamp 224 of the second side clamping part 22 slides to achieve the opening and reduction of the distance between the first side clamp 212 and the second side clamp 224. Compared with the former, the structure in which the first side clamp 212 is directly fixedly mounted on the first mounting seat 211 is simpler.

The first conveying mechanism 1 can be composed of one conveying device 11, or can be composed of two arranged conveying devices 11. Since the length of the strip-shaped product is relatively long, when the strip-shaped product is clamped at both ends of the strip-shaped product to convey the strip-shaped product, the width requirement of the first conveying mechanism 1 is also relatively large. When the first conveying mechanism 1 is composed of two arranged conveying devices 11, on the one hand, its structure is simple, and the requirement for a larger width of the first conveying mechanism 1 can be met by setting the positions of the two conveying devices 11; on the other hand, after the first conveying mechanism 1 is composed of two arranged conveying devices 11, the width of the first conveying mechanism 1 can be adjusted by adjusting the positions of the two conveying devices 11, thereby making the setting of the first conveying mechanism 1 more flexible.

Only one of the two conveying devices 11 can be slidably mounted on the two guide rods 1001 of the frame 1000, or both conveying devices 11 can be slidably mounted on the two guide rods 1001 of the frame 1000. Under this setting of the present invention, the adjusting screw 1002 is rotated to drive the corresponding conveying device 11, so that the corresponding conveying device 11 moves along the guide rod 1001, and then the width of the first conveying mechanism 1 can be adjusted, so that the first conveying mechanism 1 can be used in the clamping and conveying of strip products of different sizes. In the clamping and conveying device for strip products that does not deform or break of the present invention, when the two conveying devices 11 are slidably mounted on the two guide rods 1001 of the frame 1000, the cam block 3 is usually correspondingly detachably mounted on the frame 1000, so that when the conveying device 11 on which the second side clamping portion 22 is arranged is adjusted, after the conveying device 11 moves, the position of the cam block 3 on the frame 1000 can also be adjusted accordingly, so that the guide track 31 of the cam block 3 can always be located on the conveying path of the guide member 225, and guide the operation of the guide member 225.

[0054] The clamping and conveying device for non-deformable and non-breakage strip products of the present invention, the conveying device 11 is slidably installed on the two guide rods 1001 of the frame 1000, specifically, the driving wheels at both ends of the conveying device 11 are respectively slidably installed on the two guide rods 1001 of the frame 1000.

[0059] like Figure 1 , Figures 10 to 14 As shown, a screening device for non-deformed and non-breakage strip products comprises a conveying device 100, wherein the conveying device 100 comprises a clamping conveying device 10 and a lying conveying device 20 of the present invention, wherein the clamping conveying device 10 is connected to the strip product conveying path on the lying conveying device 20; the lying conveying device 20 comprises a second conveying mechanism 201, wherein the second conveying mechanism 201 is horizontally provided with a plurality of strip product placement slots 202, and both ends of the strip product placement slots 202 are open; in the clamping conveying device 10, the first conveying mechanism 1 is vertically provided with a body imaging camera 401 to obtain body surface image data of the strip product except the two ends, and the second conveying mechanism 201 is horizontally provided with end imaging cameras 402 to obtain surface image data of the corresponding side ends of the strip product on both sides.

[0060] The screening equipment for strip products which does not deform or break of the present invention, when in operation, the strip products 2000 are continuously transported on the clamping conveying device 10 and the lying conveying device 20 of the conveying device 100 by the clamping conveying device 10 and the lying conveying device 20; wherein, the conveying order of the clamping conveying device 10 and the lying conveying device 20 can be from the clamping conveying device 10 to the lying conveying device 20, or from the lying conveying device 20 to the clamping conveying device 10.

[0061] In the screening device for strip products that do not deform or break of the present invention, when the strip product 2000 is conveyed on the clamping and conveying device 10, specifically, the two ends of the strip product 2000 are clamped between the first side clamping portion 21 and the second side clamping portion 22 of the clamping mechanism 2 on the first conveying mechanism 1, and are conveyed together with the first conveying mechanism 1. When the strip product 2000 is conveyed to the body imaging camera 401, the body imaging camera 401 photographs the body parts of the strip product 2000 except the two ends, and obtains the body surface image data of the strip product 2000 except the two ends.

[0062] In the screening device for strip products that do not deform or break, when the strip product 2000 is conveyed on the lying conveyor 20, specifically, the strip product 2000 is limited in the strip product placement slot 202 of the lying conveyor 20 and is conveyed together with the second conveying mechanism 201. When the strip product 2000 is conveyed to the end imaging camera 402, the end imaging camera 402 shoots the end of the strip product 2000 to obtain surface image data of both ends of the strip product.

[0063] The screening equipment for strip products that do not deform or break of the present invention has different structures between the clamping and conveying device 10 and the lying conveying device 20, and also has different conveying states for the strip products. Specifically, the clamping and conveying device 10 clamps the two ends of the strip products through the first side clamping portion 21 and the second side clamping portion 22 of the clamping mechanism 2 on the first conveying mechanism 1 for conveying; the lying conveying device 20 limits the strip products through the strip product placement slot 202 on the second conveying mechanism 201, and then conveys them together with the second conveying mechanism 201.

[0064] The screening equipment for the strip products of the present invention which does not deform or break is used to transport the strip products in different states front and back through the clamping conveying device 10 and the lying conveying device 20, so that different parts of the strip products can be exposed during two different conveying processes. At the same time, the body imaging camera 401 and the end imaging camera 402 are equipped to photograph different parts of the strip products transported by the clamping conveying device 10 and the lying conveying device 20 in batches, so that the complete surface image data of the strip products can be finally obtained. The surface image data of the strip products are more complete and integrated, and the accuracy of grading is also higher.

[0065] In the screening device for the strip products of the present invention that does not deform or break, preferably, the number of the body imaging cameras 401 is more than two, and the more than two body imaging cameras 401 are respectively located on the upper and lower sides of the conveying path of the strip products on the clamping and conveying device 10, and the installation angles of the more than two body imaging cameras 401 are limited to the image data of the entire body surface of the strip products except the two ends can be obtained by all the body imaging cameras 401. In order to obtain the image data of the entire body surface of the strip products except the two ends, multiple body imaging cameras 401 can be set to take pictures of the strip products on the clamping and conveying device 10 from different angles; or only one body imaging camera 401 can be set, and then, usually the body imaging camera 401 is moved and replaced, and the strip products on the clamping and conveying device 10 are taken pictures from different angles in succession. Compared with the latter, the body imaging camera 401 of the former is fixed and does not need to be shifted, so the setting is simpler and more convenient. When the number of the body imaging cameras 401 is more than two, the more than two body imaging cameras 401 are arranged along the circumference of the strip product on the clamping and conveying device 10 and distributed on the side of the strip product on the clamping and conveying device 10, and all of the body imaging cameras 401 are facing the conveying path of the strip product on the clamping and conveying device 10.

[0066] The screening device for the strip-shaped products of the present invention which does not deform or break is preferably as follows: Fig.13 As shown, there are three body imaging cameras 401, and the three body imaging cameras 401 are evenly distributed along the circumference of the strip product on the clamping and conveying device 10 and on the vertical side of the conveying path of the strip product on the clamping and conveying device 10. Among the three body imaging cameras 401, the installation angles of two of the body imaging cameras 401 differ by 120 degrees; during operation, the three body imaging cameras 401 take pictures of the body part of the strip product due to three different angles. Under this setting, the complete image data of the entire body surface of the strip product except the two ends is obtained through a small number of body imaging cameras 401.

[0067] In the screening device for strip products that do not deform or break, the installation angle of the end imaging camera 402 is limited to the end of the strip product on the lying conveying device 20. The end imaging cameras 402 are usually arranged horizontally and each faces the corresponding side of the strip product conveying path on the clamping conveying device 10.

[0068] In the non-deformed and non-fractured strip product quality inspection device of the present invention, preferably, the length D1 of the strip product placement slot 202 is smaller than the length D2 of the strip product 2000 to be inspected. Under this setting, when the strip product 2000 is transported on the lying conveying device 20, after the strip product is located in the strip product placement slot 202, the two ends of the strip product can be extended out of the strip product placement slot 202 of the second conveying mechanism 201, thereby making it more convenient for the end imaging camera 32 to shoot the ends of the strip product and obtain surface image data of the two ends of the strip product.

During the process of conveying the strip product 2000 on the conveying device 100, when the strip product 2000 is conveyed by the clamping conveying device 10 to the body imaging camera 401, the body imaging camera 401 photographs the body parts of the strip product 2000 except the two ends, and obtains the body surface image data of the strip product 2000 except the two ends. Then, the strip product 2000 is conveyed by the clamping conveying device 10 to the lying conveying device 20, and when it is conveyed by the lying conveying device 20 to the end imaging camera 402, the end imaging camera 402 photographs the ends of the strip product 2000, and obtains the surface image data of the ends of the strip product.

[0071] The screening equipment for non-deformable and non-break strip products of the present invention obtains the surface image data of the strip products through the body imaging camera 401 and the end imaging camera 402, and then grades the quality of the strip products or classifies the colors according to the image data of the strip products, and then screens the strip products of different grades or different colors; specifically, after the strip products 2000 are conveyed to the inclined conveying device 30 by the lying conveying device 20, they are conveyed by the inclined conveying device 30, and when the inclined conveying device 30 of the conveying device 100 conveys the strip products to the air nozzle 501, the strip products of corresponding grades or corresponding colors are blown out of the inclined conveying mechanism 301 through the air nozzle 501, and are output from the inclined conveying device 30, thereby completing the screening of non-deformable and non-break strip products of different qualities or different colors.

[0072] The present invention is a screening device for strip products that does not deform or break. When the inclined conveying device 30 conveys the strip products, specifically, the strip products 2000 lie horizontally and are confined in the strip product placement slot 302 on the inclined conveying mechanism 301 and are conveyed together with the inclined conveying mechanism 301.

[0073] The screening equipment for strip products that do not deform or break of the present invention is provided by arranging the inclined conveying device 30 on one side of the clamping conveying device 10 and the lying conveying device 20 close to the output end of the conveying device 100, and arranging one or more air nozzles 501 on the lower side of the conveying path of the strip products on the inclined conveying mechanism 301, so that in the process of the conveying device 100 conveying the strip products, the strip products can be first photographed by the body imaging camera 401 and the end imaging camera 402 to obtain image data of the surface of the strip products, and the quality of the strip products can be graded or different colors can be judged according to the image data of the strip products, and then the strip products of different grades or different colors can be distinguished by the air nozzles 501 to achieve screening of strip products of different qualities or different colors.

[0074] The present invention provides a screening device for non-deformable and non-breakable strip products, wherein the body imaging camera 401, the end imaging camera 402 and the air nozzle 501 can all be intelligently controlled. Under the control of the control system, a fully automated screening device can be easily formed. The screening device has high working efficiency and fast detection speed, and its intelligent detection and screening no longer rely on human eyes, so that the intensity of manual labor is greatly reduced and the accuracy of the screening results is also greatly improved.

[0075] The present invention is a screening device for non-deformed and non-fractured strip products, wherein the body imaging camera 401, the end imaging camera 402 and the air nozzle 501 are all connected to a control system; the control system controls the shooting action of the body imaging camera 401 and the end imaging camera 402, and the body imaging camera 401 and the end imaging camera 402 transmit the captured image data to the control system, which compares and grades the image data, and then controls the action of the air nozzle 501 according to the grade or color judgment to distinguish the strip products of different grades or colors. The above-mentioned intelligent control realized by the control system belongs to the existing conventional technology, and the present invention will not elaborate on this.

[0076] The screening device for strip products that do not deform or break of the present invention may be that the clamping conveying device 10, the lying conveying device 20 and the inclined conveying device 30 are sequentially distributed along the conveying direction of the conveying device 100, and the conveying path of the strip products is sequentially connected end to end, or the lying conveying device 20, the clamping conveying device 10 and the inclined conveying device 30 are sequentially distributed along the conveying direction of the conveying device 100, and the conveying path of the strip products is sequentially connected end to end. The screening device for strip products that do not deform or break of the present invention only needs to make the clamping conveying device 10 and the lying conveying device 20 located on the side of the inclined conveying device 30 close to the input end of the conveying device 100, and its function is to ensure that the strip products can be first transported by the clamping conveying device 10 and the lying conveying device 20 to the body imaging camera 401 and the end imaging camera 402 for shooting, and then transported by the inclined conveying device 30 to the air nozzle 501 for sorting.

[0077] In the screening equipment for strip products that do not deform or break of the present invention, the number of the air nozzles 501 can be one group, two groups, or three groups or more. When the air nozzles 501 are in one group, the air nozzles 501 can blow out strip products of corresponding grades or colors from the inclined conveying mechanism 301, and the remaining strip products can be naturally output and dropped by the inclined conveying mechanism 301, thus achieving screening of two grades or two colors. When the number of the air nozzles 501 is in an array, the air nozzles 501 in the array classify the quality of the corresponding strip products into several grades or several colors. The more grades or colors the strip products are classified into, the finer the quality is.

[0078] The present invention provides a screening device for non-deformed and non-breakage strip products. Specifically, the body imaging camera 401 , the end imaging camera 402 and the air nozzle 501 are all fixedly mounted on a frame on the side of the conveying path of the conveying device 100 .

The inclined conveying mechanism 301 can be composed of one inclined conveying device, or can be composed of two arranged inclined conveying devices 3011. Since the length of the strip products is relatively long, when the strip products are confined in the strip product placement slot 302 for conveying, the width of the inclined conveying mechanism 301 is usually required to be wider, and the air nozzle 501 needs to be set on the lower side of the conveying path of the inclined conveying mechanism 301. The air nozzle 501 needs to face the upper side of the conveying path of the conveying device 100 to blow the strip products out of the inclined conveying mechanism 301; in order to facilitate the arrangement of the inclined conveying mechanism 301 and the air nozzle 501, preferably, the inclined conveying mechanism 301 is composed of two horizontally arranged inclined conveying devices 3011.

Since the second conveying mechanism 201 has a strip product placement slot 202, and the inclined conveying mechanism 301 has a strip product placement slot 302, the lying conveying device 20 and the inclined conveying device 30 have basically the same structure, so the second conveying mechanism 201 and the inclined conveying mechanism 301 can be formed in one piece, consisting of the same conveying device, so that the setting is more convenient.

During operation, the strip-shaped product is placed in the feeding bin 603. Since the input end of the feeding conveying mechanism 601 is located in the feeding bin 603, the strip-shaped product in the feeding bin 603 will enter the material feeding slot 602 on the feeding conveying mechanism 601, and be transported to the input station 101 of the clamping conveying device 10 by the feeding conveying mechanism 601. Under this setting, automatic feeding can be realized, making feeding more convenient and the automation degree of the equipment higher.
