Description

Technical Field

[0001] The present invention relates to the technical field of warehouse purchase, sale, storage and utilization, and in particular to a method for inputting purchase, sale, storage and utilization information of a rice warehouse. Background Art

[0002] A rice warehouse refers to a facility or building specifically used to store rice. There are many types of rice available, and the size of each package is different. Registration is required when storing. However, when placing rice in a warehouse for storage registration, it is manually taken out one by one by a shooting mechanism for shooting, reading and registration. However, long-term manual operation is prone to fatigue and may cause errors in registration. Moreover, many rice items are randomly placed when transported to the interior of the warehouse. During shooting, the location of the package QR code needs to be found for shooting, resulting in high labor intensity and low efficiency. The rice items transported after shooting are also randomly placed. When transported to a robot for grabbing and placing, the random placement makes grabbing difficult, and manual placement is required, further reducing the efficiency. Therefore, a method for entering information on the purchase, sale and use of a rice warehouse is required. Summary of the invention

[0039] In order to realize the action of conveying rice items in the warehouse. The conveying device 2 includes a frame 21, and the relative surfaces of the two frames 21 are rotatably connected with a conveying shaft 22 through bearings. One end of the conveying shaft 22 is fixedly installed with a driving motor of the power mechanism through a coupling. A conveying roller 23 is fixedly installed on the arc surface of the conveying shaft 22, and the arc surfaces of the two conveying rollers 23 are both drivingly connected with a conveyor belt 24. A support column 25 is fixedly installed on the top of the conveyor belt 24, and the tops of the multiple support columns 25 are all provided with knurling 26, and the multiple support columns 25 are distributed in a curved array on the surface of the conveyor belt 24, and the support columns 25 are arranged to facilitate the clamping adjustment device 6 to be located below the rice items, thereby enhancing the clamping effect.

[0040] Specifically, when rice items in the warehouse need to be stored and recorded, the staff takes the rice items and places them on the top of the conveyor belt 24, so that they come into contact with the support column 25 at the top. The knurling 26 is provided to enhance the friction between the rice items and the top of the support column 25, so that the rice items are transported forward under the rotation of the conveyor belt 24.

[0041] In order to realize the synchronous telescopic action of the horizontal rotating device 4, the vertical rotating device 5 and the clamping and adjusting device 6. The telescopic device 3 includes a telescopic cylinder 31, a vertical slider 33 is fixedly installed on the mounting surface of the telescopic cylinder 31, one side surface of the vertical slider 33 is slidably plugged with the inner side wall of the U-shaped frame 7, a vertical screw 34 is threadedly connected to the surface of the vertical slider 33, both ends of the vertical screw 34 are rotatably connected to the inner top wall and the inner bottom wall of the U-shaped frame 7 through bearings, wherein the top of the vertical screw 34 penetrates and extends to the top of the U-shaped frame 7, a vertical rotating motor 35 is fixedly installed on the top of the U-shaped frame 7, the output shaft of the vertical rotating motor 35 is fixedly installed with the top of the vertical screw 34 through a coupling, and a mounting hole 32 is opened at the top of the telescopic shaft of the telescopic cylinder 31.

[0042] Specifically, after the rice object is read, if the center of the rice object does not coincide with the origin, the conveyor belt 24 is used to control the midpoint of the rice object in the X-axis direction to coincide with the origin, and then the telescopic device 3 is controlled to telescope to make the telescopic cylinder 31 extend to control the clamping adjustment device 6 to come to the surface of the rice object for clamping, and then the midpoint of the rice object in the Y-axis direction is controlled to coincide with the origin during retraction or extension.

[0043] In order to realize the vertical rotation of the rice items in the warehouse placed by the conveying device 2, the vertical rotating device 5 includes a mounting plate 51, a rotating shaft 52 is fixedly mounted on one side of the mounting plate 51, a first driving motor 53 is fixedly mounted on the inner wall of the mounting hole 32, and the output shaft of the first driving motor 53 is fixedly mounted on one end of the rotating shaft 52 through a coupling.

[0044] Specifically, when the photographed two-dimensional code of the rice item is not at the top, but on other surfaces, the telescopic device 3 is extended to the surface of the rice item to make it clamped and adjusted by the clamping adjustment device 6 to control the clamping of the rice item. After clamping, the photographed information is compared with the information stored in the system, and the system controls the first rotating motor to rotate to drive the rotating shaft 52 to rotate, thereby controlling the rotation of the mounting plate 51, driving the clamped rice item to perform a circular motion, thereby controlling the two-dimensional code to be adjusted to the top. When the size of the rice item is limited during rotation adjustment, the vertical rotating motor 35 at the top is controlled to work to drive the vertical screw 34 to rotate, thereby driving the vertical slide 33 to slide up and down in the vertical direction, thereby achieving the effect of vertical adjustment of the rice item to limit its size and assist rotation adjustment.

[0045] In order to realize the action of clamping the rice items in the warehouse placed by the conveying device 2, and to assist the rotation of the horizontal rotating device 4 and the vertical rotating device 5, the clamping adjustment device 6 includes an upper clamping plate 61 and a lower clamping plate 62, a straight slide groove 63 is provided on one side of the mounting plate 51, and a straight slider 64 is slidably inserted into the inner wall of the straight slide groove 63, and one end of the two straight sliders 64 is fixedly installed with one side of the upper clamping plate 61 and one side of the lower clamping plate 62 respectively.

[0046] Specifically, when the rice items are moved to the bottom of the U-shaped frame 7, when adjustment operation is required according to the comparison of the photographed information, the lower clamping plate 62 and the upper clamping plate 61 are controlled to move toward each other synchronously to clamp the rice items, and the sliding cooperation of the straight slide 63 and the straight slider 64 enhances the effect of limiting the upper and lower clamping plates 61 and 62 in the up and down movement.

[0047] Bearing seats 65 are fixedly installed on the top and bottom of one end of the mounting plate 51, and the relative surfaces of the two bearing seats 65 are rotatably connected with drive rods 66 through bearings. A second drive motor 67 is fixedly installed on the surface of the bearing seat 65 above the mounting plate 51, and the output shaft of the second drive motor 67 is fixedly installed on the top of the drive rod 66 through a coupling. The arc surfaces at both ends of the drive rod 66 are respectively provided with left-handed threads 68 and right-handed threads 69. The left-handed thread 68 at the top of the drive rod 66 is threadedly connected to the surface of the upper clamping plate 61, and the right-handed thread 69 at the bottom end of the drive rod 66 is threadedly connected to the surface of the lower clamping plate 62.

[0048] Specifically, during the clamping operation, the second drive motor 67 is rotated to drive the drive rod 66 to rotate, so that under the setting of the left-handed thread 68 and the right-handed thread 69 of the drive rod 66, the upper clamping plate 61 is synchronously controlled to move downward and the lower clamping plate 62 is synchronously controlled to move upward, so that the clamped rice object is separated from the support column 25.

[0049] In order to realize the horizontal rotation adjustment of the warehouse rice items placed by the conveying device 2, the horizontal rotation device 4 includes a rotation driving plate 41 and a driven rotating plate 42, a first arc-shaped slide groove 43 is provided at the bottom of the upper clamping plate 61, a first arc-shaped slider 44 is slidably inserted into the inner wall of the first arc-shaped slide groove 43, and the bottoms of the plurality of first arc-shaped sliders 44 are fixedly mounted on the top of the driven rotating plate 42.

[0050] Specifically, when the photographed rice product information is compared with the system stored information, it can be seen that the placed rice product is tilted, and the horizontal rotating device 4 is used to rotate and adjust in the horizontal direction so that the placed rice product is parallel to the X-axis and the Y-axis.

[0051] In order to achieve horizontal adjustment and correct tilting and prevent the upper clamping plate 61 from clamping rice items and being unable to move to increase friction, a second arc-shaped slide groove 45 is provided on the top of the lower clamping plate 62, and a second arc-shaped slider 46 is slidably inserted into the inner wall of the second arc-shaped slide groove 45. The tops of multiple second arc-shaped sliders 46 are fixedly installed on the bottom of the rotating drive plate 41, and a gear ring 47 is fixedly installed on the arc surface of the rotating drive plate 41.

[0052] Specifically, a plurality of second arc-shaped sliding blocks 46 are provided at the bottom of the lower clamping plate 62 to slide in a circular motion on the inner wall of the second arc-shaped sliding groove 45, thereby reducing the friction force with the rice object being clamped, and facilitating the effect of adjusting the tilt angle of the rice object in the horizontal direction.

[0054] Specifically, in the horizontal rotation adjustment, the third driving motor 49 rotates to drive the driving shaft 410 to rotate, thereby controlling the rotation of the gear 411. When the gear 411 is engaged with the ring gear 47, the gear 411 drives the ring gear 47 to rotate, thereby driving the rotating driving plate 41 to rotate, and then adjusting the placement angle of the rice items to be parallel to the X-axis and the Y-axis respectively, so as to facilitate the control of the placed rice items to be directly transported to the subsequent robot gripping position, facilitate direct gripping and placement operations, further reduce the intensity of manual labor, and enhance work efficiency.

[0055] The information entry system includes the following steps:

[0056] Step 1: First, use the conveying device 2 to convey the rice items stored in the warehouse. During the conveying, the rice items are placed randomly on the conveying device 2. The conveying direction of the conveying device 2 is set as the X-axis, the axis perpendicular to the conveying direction is set as the Y-axis, and the middle of the conveying device 2 is set as the origin.

[0057] Step 2: U-shaped frames 7 are installed on both sides of the middle part of the conveying device 2, and shooting cameras 8 are fixedly installed on the top of the U-shaped frame 7. The shooting midpoint of the shooting camera 8 and the origin of the conveying device 2 are located at the same axis. When the rice items conveyed by the conveying device 2 are transmitted to the bottom of the U-shaped frame 7, the placement information of the rice items and the information on the surface of the rice items are photographed by the shooting camera 8, and the photographed information is controlled to be transmitted to the inside of the system, and compared with the rice item storage information inside the system, so as to obtain the type of rice items placed by the conveying device 2 at this time, and the position of the QR code of the placed rice items, and the distance between the midpoint of the rice items placed by the conveying device 2 at this time and the origin.

[0058] Step 3: first adjust according to the midpoint size and origin size of the photographed rice item, control the midpoint of the X-axis size of the placed rice item to be located at the origin through the conveying operation of the conveying device 2, then control the placed rice item to be clamped through the clamping adjustment device 6, and then control the midpoint of the Y-axis size of the placed rice item to be located at the origin through the telescopic device 3, so that the midpoint of the placed rice item coincides with the origin.

[0059] Step 4: When the midpoint of the placed rice item coincides with the origin, the telescopic device 3 is controlled to extend and the clamping and adjusting device 6 is used to clamp the placed rice item, and the QR code placement position of the rice item is adjusted according to the information compared by the system.

[0060] Step 5: During adjustment, firstly, the rice items are placed and horizontally rotated in the X-axis direction with the X and Y axes as the center, so that the surfaces of the rice items are parallel to the X-axis and the Y-axis respectively, and then the vertical rotation adjustment is driven according to the compared information to control the rotation operation of the rice items so that the QR code of the rice items is located at the top. After adjustment, the clamped rice items are released to be placed on the conveying mechanism, and the conveying operation is continued.

[0061] Step 6: When the adjusted and corrected rice items continue to be transported to the rear, they enter the reading frame 9 installed on the rear surface of the conveying mechanism, and the reading camera 10 installed on the top of the reading frame 9 is used to shoot and read the two-dimensional code information of the rice items, and record and store them.

[0062] The device is provided with an error correction mechanism 1 and an information entry system. When the rice items in the warehouse are stored and registered, the staff only needs to control the rice items to be placed on the conveying device 2 at will, automatically adjust the conveying and placing angle of the rice items, and make the two-dimensional code of the placed rice items always face upward. When entering the registration shooting, the two-dimensional code information of the rice items is automatically photographed and read, and the registration and storage are automatically registered, thereby avoiding the existing manual scanning and registration. During the scanning and registration, it is also necessary to take and find the two-dimensional code and place the code, which reduces the efficiency of registration and storage. The manual labor intensity is large, and the manual reading operation for a long time is fatigued, which is easy to cause omissions and registration errors. The fully automatic reading and registration operation of the present invention saves labor costs, improves work efficiency, reduces erroneous operations, and makes the registration and storage information perfect.
