[0002] Warehouse management technology has been widely used in manufacturing, retail and other fields, greatly improving logistics efficiency and accuracy. At present, some automated warehousing systems use a large number of large-scale storage equipment such as high-rise shelves, handling equipment such as pallets, forklifts, and lifts, as well as automatic transmission tracks and information management systems to achieve warehouse automation. However, the current shelves lack accurate metering functions and cannot accurately record the consumption and remaining quantity of long goods (such as cables, etc.). There are still obvious deficiencies in real-time tracking of long goods. In terms of managing long goods, there are problems such as low automation level, high warehousing operation costs, and high manpower requirements, which affect the accuracy and efficiency of inventory management. Summary of the invention

[0003] Given that current shelves lack accurate metering functions and are unable to accurately record the consumption and remaining quantities of long goods (such as cables, etc.), there are still obvious deficiencies in real-time tracking of the dynamics of long goods. In terms of managing long goods, there are problems such as low automation level, high warehousing operation costs, and high manpower requirements, which affect the accuracy and efficiency of inventory management. This application proposes a shelf that can accurately record the consumption and remaining quantities of long goods (such as cables, etc.).

[0004] In a first aspect, the present application proposes a meter-based smart shelf and adopts the following technical solution.

[0006] The wire coil holder, the meter sensor, the fixed clamp and the cutting module are all installed on the lower body; the movable clamp is installed on the upper body; and the controller is electrically connected to the meter sensor, the fixed clamp, the cutting module and the movable clamp.

[0008] By adopting the above technical solution, the meter sensor installed on the shelf can measure the length of the wire consumed by cutting. According to the known length of the wire coil, the remaining length of the wire coil can be obtained, and the cutting and measuring process can be completed automatically, thereby improving the level of automation in managing long goods, reducing warehouse operating costs, reducing manpower requirements, and improving the accuracy and efficiency of inventory management.

[0009] A preferred solution of the meter-meter smart shelf is that the fixing clamp further includes a front rotator, a front shaft and a front track; the front clamp includes a first slider and a second slider.

The blade and the gap between the double-layer board are in the same plane; the cutting edge of the front end of the blade faces the gap between the double-layer board. The left telescope can drive the blade to move toward the double-layer board, and the right telescope can drive the double-layer board to move toward the blade, so that the cutting edge of the blade is inserted into the gap between the double-layer board.

[0014] By adopting the above technical solution, the cutting module can be separated into two completely non-contact parts, and the passage between the two parts can allow the rear clip to pass through without hindrance.

[0015] A preferred solution of the meter-meter smart shelf is that the end of the double-layer board away from the blade is a closed block; the rear end of the blade is a blocking block with a width greater than the width of the gap between the double-layer board; when the blocking block abuts against the double-layer board, the edge of the blade does not contact the closed block of the double-layer board.

[0016] By adopting the above technical solution, the rear end of the blade abuts against the blocking block while the tissue blade continues to move forward, so that the blade edge does not contact the closing block, reducing the risk of blade edge damage.

[0017] A preferred solution of the meter-meter smart shelf is that the maximum thickness of the blade inserted into the double-layer board is 0-1 mm smaller than the gap width of the double-layer board.

[0018] By adopting the above technical solution, the blade can be adaptively inserted into the gap between the double-layer boards, the gap between the blade and the double-layer boards is small, and the wire can be cut neatly.

[0019] A preferred solution of the meter-meter smart shelf is that the mobile clamp also includes a driving mechanism, a mobile frame, a rear rotator, a rear shaft and a rear track. The rear clamp includes a third slider and a fourth slider.

[0020] By adopting the above technical solution, the driving mechanism can drive the third slider and the fourth slider to pass over the cutting module and approach the front clip to clamp the thread on the front clip.

[0021] A preferred solution of the meter-counting smart shelf is that the driving mechanism includes an upper rotator, an upper shaft, an upper track, an upper slider and a connecting rod. The upper rotator and the upper track are both installed on the upper body; the upper rotator is connected to one end of the upper shaft, and the other end of the upper shaft is connected to the upper body through a bearing; the upper shaft passes through the upper slider; the upper shaft and the upper slider are connected through a thread; the upper slider is slidably installed on the upper track; the upper track is parallel to the upper shaft; one end of the connecting rod is connected to the upper slider, and the other end is connected to the mobile rack.

[0022] By adopting the above technical solution, the upper rotator drives the upper shaft to rotate, driving the movable frame to move forward and backward. The moving direction is parallel to the axial direction of the wire body, so that the third slider and the fourth slider on the movable frame can move in an axial direction parallel to the wire body, so that the third slider and the fourth slider located on both sides of the wire body can clamp the wire body and pull the wire body out axially for the cutting module to cut it.

[0023] A preferred solution of the meter-counting smart shelf is that the meter-counting smart shelf also includes a limit tube; one end of the limit tube is a bell mouth, the bell mouth faces the wire coil holder, and the other end faces the meter-counting module.

[0024] By adopting the above technical solution, the limiting tube supports and guides the easily deformed wire body, and the bell mouth facilitates the wire body starting from various positions of the wire reel to smoothly enter the limiting tube, thereby reducing the risk of damage to the wire body.

[0025] On the second aspect, the present application also proposes a meter counting method and adopts the following technical solution.

[0027] S2, the controller controls the cutting module to be in a state of giving way to the rear clamp, opens the rear clamp, drives the rear clamp to move forward to pass through the cutting module and approach the front clamp, drives the rear clamp to clamp the wire body, then opens the front clamp, drives the rear clamp to move backward a distance to pull the wire body out a distance, and the meter sensor senses the distance the wire body moves during this process.

[0028] S3, then the front clamp clamps the wire, and step S2 is repeated several times until the meter sensor measures that the length of the pulled wire reaches the target length to be taken this time, and the controller controls the cutting module to cut the wire.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] like Figure 1 A meter-counting intelligent shelf includes a frame 1, a wire coil holder 2, a limit tube 3, a meter-counting sensor 4, a fixing clamp 5, a cutting module 6, a moving clamp 7 and a controller, and may also include a display screen.

[0039] The frame 1 comprises an upper body 101 and a lower body 102. The upper body 101 and the lower body 102 can be long plates parallel to each other. The upper body 101 and the lower body 102 can also be a frame structure in which a plurality of square tubes are connected horizontally and vertically.

[0040] The wire coil holder 2, the stop tube 3, the meter sensor 4, the fixing clamp 5 and the cutting module 6 are roughly in the same straight line and are installed from front to back on the lower body 102. From front to back means from one end to the other end of the lower body 102. The base of the movable clamp 7 is installed on the lower surface of the upper body 101, and the other part extends downward to be in the same straight line with the cutting module 6, etc., so as to clamp the wire body 8.

[0041] The controller is electrically connected to the meter sensor 4, the fixing clamp 5, the cutting module 6, the moving clamp 7 and the display screen. The display screen can be mounted on the frame 1.

[0042] The wire 8 can be wound on the wire coil holder 2, and the length of the wire 8 can be measured in advance, or the wire 8 in a coiled form, i.e., a wire coil, can be purchased, and its length can be obtained from the package or from the supplier. The wire 8 is a long-shaped cargo, specifically a linear object, such as a cable.

[0043] The initial installation method of the wire body 8 can be, firstly, winding the wire coil on the wire coil holder 2, pulling out the end from the wire coil, that is, pulling out the wire body 8, passing the wire body 8 through the limiting tube 3 and passing through the sensing area of ​​the meter sensor 4, and then passing the wire body 8 through the fixing clamp 5, the fixing clamp 5 clamps the wire body 8, and the cutting module 6 and the movable clamp 7 wait at the back to process the wire body 8.

[0044] The end of the position limiting tube 3 facing the wire coil holder 2 is a bell mouth, which facilitates the wire body 8 on the wire coils of various specifications to smoothly pass into the position limiting tube 3. The wire body 8 can be a cable, etc. The other end of the position limiting tube 3 faces the meter sensor 4, so that after the wire body 8 passes through the position limiting tube 3, it can pass by the side of the meter sensor 4, so that the meter sensor 4 senses and measures the length of the wire body 8 that has moved.

[0045] The meter sensor 4 can adopt the BETA cable laser meter meter supplied by Kunshan Jierongfa Measurement and Control Equipment Co., Ltd., model LS9500-410, which can accurately measure the length of the moving wire body 8.

[0046] like Figure 2The fixing clamp 5 includes a front clamp 501, a front rotator 502, a front shaft 503 and a front track 504. The front rotator 502 can be a motor. The front clamp 501 includes a first slider 5011 and a second slider 5012. The front rotator 502 and the front track 504 are both installed on the upper surface of the lower body 102. The front rotator 502 is connected to one end of the front shaft 503, and the other end of the front shaft 503 is connected to a bearing, which is installed on the upper surface of the lower body 102. The front shaft 503 and the front track 504 are parallel and perpendicular to the forward direction of the line body 8. The first slider 5011 and the second slider 5012 each have a through hole, and an internal thread is arranged on the inner surface of the through hole, and the internal thread of the first slider 5011 and the internal thread of the second slider 5012 are in opposite directions. The lower end of the first slider 5011 and the lower end of the second slider 5012 are both embedded in the front track 504, so that the first slider 5011 and the second slider 5012 can slide on the front track 504. The front shaft 503 passes through the through hole of the first slider 5011 and the through hole of the second slider 5012. The front shaft 503 has two sections of external threads in opposite directions, and the two sections of opposite external threads are respectively adapted to connect the internal threads of the first slider 5011 and the internal threads of the second slider 5012, so that when the front rotator 502 drives the front shaft 503 to rotate, the first slider 5011 and the second slider 5012 can move relative to each other, that is, move away from each other or approach each other and press against each other, so as to clamp the wire body 8. A soft pad 5013 can be installed on the inner side of each of the first slider 5011 and the second slider 5012. The two soft pads 5013 are opposite to each other, so that when the first slider 5011 and the second slider 5012 are close to each other, the two soft pads 5013 can be pressed against each other to clamp the wire body 8. In this method, the soft pad 5013 contacts the wire body 8 to reduce damage to the wire body 8.

[0047] like Figure 3, the cutting module 6 includes a left telescope 601, a blade 602, a double-layer plate 603 and a right telescope 604. The left telescope 601 and the right telescope 604 can both be electric cylinders. The left telescope 601 and the right telescope 604 are arranged opposite to each other, and the telescopic axis of the left telescope 601 and the telescopic axis of the right telescope 604 are on the same straight line and are perpendicular to the direction of movement of the line body 8. The telescopic axis of the left telescope 601 is connected to the blade 602, and the telescopic axis of the right telescope 604 is connected to the double-layer plate 603. The end of the blade 602 facing the double-layer plate 603 is the front end, and the end facing away from the double-layer plate 603 is the rear end. The end of the double-layer plate 603 facing the blade 602 is the front end, and the end facing away from the blade 602 is the rear end. The double-layer plate 603 includes two parallel plates, and there is a gap between the two parallel plates for inserting the blade 602. The rear end of the double-layer plate 603 is a closed block 6031, which fixes the two parallel plates to each other. The telescopic shaft of the right telescoping device 604 is connected to the closing block 6031. The front end of the blade 602 is a cutting edge 6021, and the rear end is a blocking block 6022 whose width is greater than the width of the gap between the double-layer plates 603. When the blade 602 is inserted into the gap between the double-layer plates 603, the blocking block 6022 abuts against the double-layer plates 603, so that the cutting edge 6021 of the blade 602 cannot contact the blocking block 6022, thereby protecting the cutting edge 6021.

[0048] like Figure 4 The mobile clamp 7 includes a driving mechanism 701, a mobile frame 702, and a rear rotator 703. Figure 5 The mobile clamp 7 further includes a rear rotating shaft 704, a rear track 705 and a rear clamp 706. The rear clamp 706 includes a third slider 7061 and a fourth slider 7062.

[0049] like Figure 4 , the driving mechanism 701 includes an upper rotator 7011, an upper track 7012, an upper shaft 7013, an upper slider 7014 and a connecting rod 7015. The upper rotator 7011 and the upper track 7012 are both mounted on the lower surface of the upper body 101. The upper rotator 7011 can be a motor, which is connected to one end of the upper shaft 7013. The upper shaft 7013 can be a screw. The other end of the upper shaft 7013 is connected to a bearing, which is mounted on the lower surface of the upper body 101. The upper shaft 7013 and the upper track 7012 are parallel and are both parallel to the direction in which the line body 8 moves. The upper end of the upper slider 7014 is adaptively sleeved on the upper track 7012, so that the upper slider 7014 can slide along the upper track 7012. A through hole is opened in the middle of the upper slider 7014, and an internal thread is provided on the inner wall of the through hole. The upper rotating shaft 7013 passes through the through hole of the upper slider 7014 to form an adapted threaded contact. When the upper rotator 7011 is started, the upper slider 7014 can move along the upper rotating shaft 7013. The upper end of the connecting rod 7015 is connected to the upper slider 7014, and the lower end is connected to the upper surface of the moving frame 702.

[0050] like Figure 3 , the movable frame 702 can be a long strip with an inverted U-shaped cross-section, opening downward. The rear track 705 is installed on the inner top surface of the movable frame 702. The rear rotator 703 is installed at one end of the movable frame 702. The rear shaft 704 is located in the movable frame 702, one end of the rear shaft 704 is connected to the rear rotator 703, and the other end is connected to a bearing, which is installed at the other end of the movable frame 702. The rear shaft 704 is parallel to the rear track 705 and perpendicular to the direction of movement of the line body 8. The upper end of the third slider 7061 and the upper end of the fourth slider 7062 are embedded in the rear track 705, so that the third slider 7061 and the fourth slider 7062 can slide along the rear track 705.

[0051] The rear shaft 704 has two opposite external threads. The third slider 7061 and the fourth slider 7062 are both provided with through holes, and the through holes are engraved with internal threads, and the internal threads of the third slider 7061 and the fourth slider 7062 are in opposite directions. The rear shaft 704 passes through the through holes of the third slider 7061 and the through holes of the fourth slider 7062, so that the two opposite external threads of the rear shaft 704 are respectively adapted to connect the internal threads of the third slider 7061 and the fourth slider 7062, so that when the rear rotator 703 drives the rear shaft 704 to rotate, the third slider 7061 and the fourth slider 7062 can slide relatively close to and abut against or move away from each other to clamp the wire body 8 or loosen the wire body 8. Soft pads 5013 can be installed on the inner side surfaces of the lower ends of the third slider 7061 and the fourth slider 7062. The two soft pads 5013 are opposite to each other. When the third slider 7061 and the fourth slider 7062 slide close to each other, the two soft pads 5013 can clamp the wire body 8, which reduces the damage to the wire body 8.

[0052] The left retractor 601 and the right retractor 604 can completely separate the blade 602 and the double-layer plate 603. Under the action of the driving mechanism 701 of the movable clamp 7, the third slider 7061 and the fourth slider 7062 can pass through the channel between the blade 602 and the double-layer plate 603, so that the third slider 7061 and the fourth slider 7062 can be close to the front clamp 501. The closeness can be that the rear clamp 706 and the front clamp 501 are abutted, or the distance between the rear clamp 706 and the front clamp 501 is small, so as to be sufficient to clamp the wire body 8 on the rear clamp 706. For example, the distance is 0.5~3cm, or it can be less than 0.5cm or greater than 3cm. This application does not make specific restrictions. During the operation of the smart shelf, after the wire 8 is cut by the cutting module 6, the length of the wire 8 exposed from the front clip 501 is the distance between the front clip 501 and the cutting module 6. However, since the wire 8 can bend downward, the exposed length of the wire 8 may be smaller than the distance between the front clip 501 and the cutting module 6. Therefore, the third slider 7061 and the fourth slider 7062 are arranged to be close to the front clip 501, so as to be sufficient to clamp the wire 8 exposed backward from the front clip 501.

[0053] The meter counting method of the meter counting type intelligent shelf may include the following steps.

[0054] S1, wind the wire coil around the wire coil holder 2, pull out the wire body 8 from the lower end of the wire coil, then pass the wire body 8 through the limiting tube 3, then pass through the side of the meter sensor 4, and then pass through the fixing clamp 5, and the controller controls the front clamp 501 of the fixing clamp 5 to clamp the wire body 8.

[0055] S2, the controller controls the two parts of the cutting module 6 to separate from each other, that is, the blade 602 and the double-layer plate 603 are separated from each other, so that the rear clamp 706 can pass through. The controller controls the upper rotator 7011 to start, so that the mobile frame 702 moves forward, driving the rear clamp 706 to move toward the front clamp 501. This moving process will first pass through the channel between the blade 602 and the double-layer plate 603, and then approach the front clamp 501. Then the rear clamp 706 clamps the wire body 8, and then the front clamp 501 releases the wire body 8. The upper rotator 7011 is started again, driving the mobile frame 702 to move backward, so that the rear clamp 706 clamps the wire body 8 and moves backward, pulling the wire body 8 backward for a distance. The meter sensor 4 senses the distance moved by the wire body 8 during this process. The controller displays the distance moved by the wire body 8 on the display screen and displays the remaining amount of the wire roll.

[0056] S3, then the front clamp 501 clamps the wire 8 again. If the length of the wire 8 has reached the target length, the cutting module 6 can be directly started to cut the wire 8. If the target length has not been reached, S2 can be repeated multiple times to pull out the required target length, and then cut the wire 8.

[0057] The cut wire body 8 is put into use. After cutting, the end of the wire body 8 on the shelf is located at the front side of the cutting module 6, but because the wire body 8 may be bent downward, the rear clamp 706 must pass through the cutting module 6 to approach the front clamp 501 to clamp the wire body 8 during actual operation.

[0058] This application can also deploy AGV carts to automatically transport goods. The AGV carts are equipped with laser radar and visual sensors, and automatically travel on a preset path. When encountering obstacles, they can respond quickly to ensure that the goods are delivered to the designated location safely and accurately.

[0059] The present application integrates a meter sensor 4 in the smart shelf to monitor the change in the length of goods in real time. When long goods such as cables are pulled out, the meter sensor 4 automatically identifies and calculates the length. The controller transmits the data to the cloud management system through the Internet of Things technology to instantly update the inventory data, thereby achieving accurate measurement and real-time tracking of long goods, improving the transparency and accuracy of inventory management, reducing labor costs, effectively controlling storage costs, and enhancing the responsiveness and competitiveness of the entire supply chain.

[0060] Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
