Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, specifically to an intelligent statistical device for photographing and analyzing pallet cartons. Background Technology

[0002] In the warehousing and logistics industry, materials such as cartons and pallets are often stacked in multiple layers on pallets and transported in bulk using forklifts. To ensure traceability and inventory accuracy in the logistics process, pallet scanning and inspection are required during the entry and exit of materials from and through various stages of the logistics chain to complete key operations such as barcode identification and quantity comparison.

[0003] Currently, the mainstream method of scanning entire pallets relies on manual scanning using PDAs. This method has significant drawbacks: First, it is inefficient, taking 3-5 minutes to scan a pallet of materials, which is difficult to meet the high-efficiency circulation requirements of large-scale warehousing; second, it is susceptible to human factors, with frequent missed scans and incorrect scans, leading to reduced inspection accuracy; and third, it has high labor costs, requiring multiple people to operate at a single workstation, and prolonged manual operation can easily lead to fatigue, further increasing the risk of misoperation.

[0004] Although some scenarios have tried using solutions such as dynamic access gates or top-suspended volume cameras, dynamic access gates have strict requirements on the material transport path and are prone to incomplete recognition due to obstruction; top-suspended cameras can only cover the top and part of the side materials, and cannot achieve full recognition of materials on all four sides of the pallet, still requiring a lot of manual assistance to supplement the data, which is difficult to meet the needs of industrial automation for efficiency improvement, quality optimization and personnel allocation optimization. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing an intelligent statistical device for photographing pallet cartons. This device replaces the manual scanning method in the prior art by providing two flexible implementation methods, which makes it more efficient, accurate in recognition and less dependent on manual labor.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A smart statistical device for photographing pallet cartons includes a loading platform for carrying goods and a photographing component for photographing and recognizing the goods on the loading platform.

[0008] The loading platform rotates around its central axis while the camera component remains fixed in position, causing the cargo to undergo circumferential angular displacement within the field of view of the camera component; or

[0009] The camera module moves in a circle around the center of the cargo platform, while the cargo platform remains fixed, so as to achieve a surround-type camera capture of the cargo.

[0010] As a further embodiment of this invention: when the platform rotates around its central axis and the position of the imaging component is fixed:

[0011] The cargo platform includes a landing frame and a turntable that is rotated on top of the landing frame. The landing frame is equipped with a first drive source for driving the turntable to rotate.

[0012] The camera assembly includes a rack located next to the cargo platform and a tray on the rack. A camera is mounted on the tray, with the camera lens facing the storage area at the top of the cargo platform.

[0013] As a further embodiment of this utility model: the first driving source includes a first motor located outside the floor frame, the output shaft of the first motor is provided with a driving wheel, a driven wheel is fixedly provided at the center of the bottom of the turntable, and the driven wheel is rotatably mounted on the floor frame, and a transmission belt is sleeved between the driven wheel and the driving wheel.

[0014] As a further embodiment of this utility model: the tray is horizontally slidable on the frame to make the distance between the camera and the top placement area of ​​the loading platform adjustable.

[0015] As a further embodiment of this utility model: a crossbeam for horizontal sliding of the pallet is fixedly provided on the frame, and a second drive source for driving the pallet to move is provided on the crossbeam.

[0016] As a further embodiment of this utility model: the second driving source includes a second motor fixedly mounted on the crossbeam, a threaded screw is rotatably mounted inside the crossbeam along its length, and the threaded screw is connected to the output shaft of the second motor for transmission, a slider slides horizontally on the crossbeam, and the slider is threadedly sleeved on the outside of the threaded screw, and the support plate is mounted on the slider.

[0017] As a further embodiment of this utility model, the device also includes a ranging sensor mounted on the frame, and both the ranging sensor and the second motor are electrically connected to the industrial control computer, and the second motor is controlled by the industrial control computer.

[0018] As a further embodiment of this utility model: the frame is equipped with an obstacle avoidance radar and a flashing warning light.

[0019] As a further embodiment of this utility model, a supplementary light is provided on the frame.

[0020] As a further embodiment of this utility model: when the photographing component moves in a circular motion around the center of the carrying platform, and the carrying platform is fixed:

[0021] The camera assembly includes a ring-shaped ground rail located outside the cargo platform, and the ring-shaped ground rail is coaxial with the central axis of the cargo platform. A traveling bracket is movably mounted on the ring-shaped ground rail, and a third motor is fixedly mounted on the traveling bracket. A gear is mounted on the output shaft of the third motor. An internal gear ring is coaxially mounted on the inner side of the ring-shaped ground rail, and the internal gear ring is meshed with the gear.

[0022] The camera assembly also includes a frame mounted on a walking support and a tray mounted on the frame, with a camera mounted on the tray and the camera lens facing the storage area on top of the cargo platform.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Two flexible implementation methods are proposed to replace the existing manual barcode scanning method. Both methods effectively achieve 360-degree information collection of goods without blind spots. The first method uses a rotating platform, which has the advantages of a fixed imaging component, ensuring stable camera installation, simple wiring, reduced complexity and cost of moving parts, and ensuring the stability of the imaging light source. The second method uses a rotating imaging component, which has the advantages of a fixed platform, making it very suitable for heavy or large goods, avoiding the instability risks that may be caused by rotating pallets, and allowing for more flexible design of the imaging path.

[0025] 2. The specific implementation of the first method, through the combination of a ground frame and a turntable, provides a stable and reliable rotating support foundation. The introduction of the primary drive source enables automated rotation of the turntable without manual intervention, improving efficiency. Simultaneously, the imaging component consists of a camera supported by a frame and a tray. This robust structural design effectively prevents camera shake, ensuring image clarity and laying the foundation for high-precision image recognition.

[0026] 3. The first drive source adopts a combination of motor, drive pulley, driven pulley and transmission belt (such as synchronous belt), which provides smooth transmission, low noise and sufficient torque to drive the turntable that may be heavily loaded.

[0027] 4. By sliding the pallet horizontally, the distance between the camera and the goods can be easily adjusted. This allows the same device to adapt to pallets and goods of different sizes. By adjusting the distance, the optimal field of view can be obtained, enabling panoramic shooting of the entire pallet or zooming in to capture details of specific areas, greatly expanding the application range of the equipment.

[0028] 5. By setting a crossbeam as a precise guiding mechanism and introducing a second drive source, the automatic and programmed adjustment of the camera distance is realized, which not only improves the efficiency and accuracy of the adjustment, but also avoids the inconvenience and errors of manual operation.

[0029] 6. By using a distance sensor to provide feedback on the actual distance between the camera and the goods, the industrial control computer can precisely control the operation of the second motor, enabling the camera to automatically move to the preset optimal position and further ensure the clarity of the captured images.

[0030] 7. The combination of obstacle avoidance radar and flashing alarm can detect whether there are people or obstacles intruding into the work area around the device, thereby alerting the driver or operator to prevent collision accidents and protect the safety of personnel and equipment.

[0031] 8. A fill light can provide stable, uniform and sufficient illumination for the camera, reducing interference factors such as shadows, reflections and uneven brightness.

[0032] 9. The second implementation method employs a circular ground rail and internal gear ring transmission, which supports the camera assembly in smooth circular motion with high accuracy and low vibration, ensuring that every frame captured during the motion is clear and usable. Furthermore, this method is suitable for static scanning of oversized and overweight cargo, avoiding the energy consumption and risks associated with rotating large loads.

[0044] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0045] The existing scanning method involves manual scanning using a PDA. To address the shortcomings of this method, this application provides a pallet and carton photographic intelligent statistical device, comprising a loading platform 1 and a photographing component 2. The loading platform 1 supports a pallet loaded with goods (e.g., carton) a, and the photographing component 2 photographs the goods a to identify whether there is a barcode on the outer wall of the goods a, or to identify whether the barcode is abnormal. Simultaneously, it performs counting and statistics to achieve accurate warehousing and / or outbound of the goods a.

[0046] Since goods A are stacked on the pallet, the entire goods on the pallet have barcodes on all four sides, requiring scanning of all four sides. Below, two solutions, Example 1 and Example 2, are presented respectively:

[0047] Example 1:

[0048] like Figures 1-6 As shown, the loading platform 1 is set to rotate around its central axis, while the position of the imaging component 2 is fixed, so that the cargo a undergoes circumferential angular displacement within the field of view of the imaging component 2. Specifically:

[0049] (1) The loading platform 1 includes a ground frame 101 installed on the ground at the warehouse inlet and / or outlet. A turntable 102 is rotatably installed on the top of the ground frame 101, and auxiliary wheels 19 are installed around the ground frame 101. The multiple auxiliary wheels 19 are arranged in a ring to provide rolling support to the bottom side of the turntable 102, so that when the turntable 102 rotates around its center point, the multiple auxiliary wheels 19 can play a stable support role. In order to enable the turntable 102 to rotate, a first drive source is provided on the ground frame 101 to drive the turntable 102 to rotate.

[0050] (2) The camera assembly 2 includes a frame 201 located next to the loading platform 1 and a tray 202 located on the frame 201. A camera 203 is mounted on the tray 202, and the lens of the camera 203 faces the storage area at the top of the loading platform 1. The storage area is used for placing a pallet loaded with goods a.

[0051] Taking the setting of two sets of photo-taking components 2 as an example, when a pallet loaded with goods a is forked onto the turntable 102 by a forklift, the two sides of goods a are respectively facing the two sets of photo-taking components 2. This state can be achieved by... Figure 1 and Figure 3 To illustrate, the two sets of photographing components 2 can respectively photograph both sides of the cargo a. After the photographing is completed, the first drive source drives the turntable 102 to rotate until the cargo a is adjusted to a 90-degree angle, so that the other two sides of the cargo a are facing the two sets of photographing components 2. This state can be achieved by... Figure 5 To illustrate, at this time, the two sets of camera components 2 can take pictures of both sides of the cargo a, thereby achieving full photography of all four sides of the cargo a.

[0052] like Figure 4 As shown, the first drive source described above includes a first motor 3 located outside the floor frame 101. The output shaft of the first motor 3 has a drive wheel 4, and a driven wheel 5 is fixedly located at the center of the bottom of the turntable 102. The driven wheel 5 is rotatably mounted on the floor frame 101, and a transmission belt 6 is fitted between the driven wheel 5 and the drive wheel 4. The rotation of the output shaft of the first motor 3 drives the driven wheel 5 to rotate, thereby driving the turntable 102 to drive the cargo a.

[0053] Since goods A are stacked on pallets, to avoid goods A being in the middle that cannot be identified by photos, the stacking method can be adjusted to avoid goods A appearing in the middle, or it can be combined with... Figure 1 As shown, the middle position is left blank.

[0054] In order for the photographic component 2 to perform photographic recognition processing on goods a of different types and sizes, in this embodiment, the pallet 202 is horizontally slidable on the frame 201, so that the distance between the camera 203 and the top storage area of ​​the loading platform 1 is adjustable. When the volume of goods a is small, causing the side of goods a to be far from the lens of the camera 203, the pallet 202 can be moved toward the side of goods a until the photographic range of the camera 203 lens can encompass the side of goods a.

[0055] For the movable arrangement of the tray 202 on the frame 201, a crossbeam 7 for horizontal sliding of the tray 202 can be fixedly installed on the frame 201, and a second drive source for driving the tray 202 to move is provided on the crossbeam 7. The second drive source can be a conventional technology in the prior art, such as a cylinder, an electric push rod, etc. In order to ensure the precise movement of the camera 203, this embodiment preferably sets the second drive source as a screw-slider mechanism. Therefore, the second drive source includes a second motor 8 fixedly installed on the crossbeam 7, a threaded screw (not shown in the figure) is rotatably installed inside the crossbeam 7 along its length direction, and the threaded screw is connected to the output shaft of the second motor 8. A slider 9 slides horizontally on the crossbeam 7, and the slider 9 is threadedly sleeved on the outside of the threaded screw. The tray 202 is installed on the slider 9. When the second motor 8 is driven to work, the threaded screw can be rotated, realizing the movement of the slider 9 on the crossbeam 7, that is, driving the camera 203 to adjust its position.

[0056] Furthermore, in order to automatically measure the distance between the lens of camera 203 and the side of cargo a, this embodiment provides a distance sensor 10 on the frame 201. The distance sensor 10 is electrically connected to the industrial control computer. At the same time, the second motor 8 can also be electrically connected to the industrial control computer. The distance sensor 10 can transmit the measured distance signal to the industrial control computer. After processing by the industrial control computer, it controls the output shaft of the second motor 8 to perform corresponding forward or reverse rotation actions, thereby increasing or decreasing the distance between camera 203 and the side of cargo a.

[0057] Meanwhile, in order to avoid the dim lighting in the storage area making it difficult for the camera 203 to take accurate pictures and identify images, this embodiment provides a supplementary light 13 on the rack 201 to illuminate the shooting range of the camera 203 and compensate for the insufficient light in the surrounding environment.

[0058] Since the camera module 2 is installed at the warehouse inlet and / or outlet, its position may fall into the travel path of forklifts or overhead cranes passing through the inlet and / or outlet. At best, the camera module 2 will be scratched, causing its position to shift and requiring readjustment; at worst, it will be collided with and run over, resulting in damage. Therefore, this embodiment includes an obstacle avoidance radar 11 and a flashing warning light 12 on the frame 201. When a forklift or overhead crane moves into the monitoring range of the obstacle avoidance radar 11, the flashing warning light 12 emits a flashing signal to alert the driver or operator. The obstacle avoidance radar 11 and the flashing warning light 12 can both be connected to the aforementioned industrial electromechanical system, or they can be connected to other control systems on site; this is not limited in this document.

[0059] It should be noted that the initial standard image recognition state in this embodiment is... Figure 3 As shown, during the process of placing a pallet loaded with goods a onto the loading platform 1, it is necessary to find the correct unloading angle for the forklift to place the pallet on the loading platform 1 in order to achieve the desired effect. Figure 3 The two cameras 203 shown are positioned facing the two sides of the cargo a, respectively. Subsequent image recognition and processing can be performed directly using the cameras 203. However, this method of unloading heavily relies on the driver's experience and skill, making it difficult to guarantee consistent results every time. Figure 3 The state shown. For the most part, cargo a on platform 1 is in the following state. Figure 6 In the state shown, it is necessary to control the turntable 102 on the cargo platform 1 to rotate until the two sides of the cargo a are directly facing the two cameras 203.

[0060] Example 2;

[0061] like Figures 7-9 As shown, the camera component 2 is configured to move in a circular motion around the center of the cargo platform 1, while the cargo platform 1 remains fixed, to achieve a surround-type photographic capture of the cargo a by the camera component 2. Specifically:

[0062] The camera component 2 includes a driver and a camera:

[0063] Drive section: A ring-shaped ground rail 14 is located outside the loading platform 1, and the ring-shaped ground rail 14 is coaxial with the central axis of the loading platform 1. This state can be achieved by... Figure 7 To illustrate, the movement of the traveling support 15 on the annular ground rail 14 is described as follows: the traveling support 15 is movably mounted on the annular ground rail 14, and the bottom of the traveling support 15 is provided with rollers located in the slide rail of the annular ground rail 14. A third motor 16 is fixedly mounted on the traveling support 15, and a gear 17 is provided on the output shaft of the third motor 16. An internal gear ring 18 is coaxially mounted on the inner side of the annular ground rail 14, and the internal gear ring 18 is meshed with the gear 17.

[0064] The photographing component: The walking support 15 is equipped with the same frame 201 as described above. The frame 201 is equipped with the same support plate 202, camera 203, distance sensor 10, obstacle avoidance radar 11, flashing warning light 12, second drive source, and supplementary light 13 as described above. That is, the photographing component in this embodiment is the same as the photographing component 2 described above. The difference is that the photographing component in this embodiment is mounted on the walking support 15 and can move with the walking support 15.

[0065] When the third motor 16 is activated, the meshing of gear 17 and internal gear ring 18 drives the traveling bracket 15 to move along the slide of the annular ground rail 14, thus enabling the camera 203 to move. Taking a setup with two sets of cameras as an example, when the two sets of cameras 203 move synchronously to face each other on opposite sides of the cargo a, the machine stops, and the two cameras 203 take pictures of each side of the cargo a. After processing these two sides, the two cameras 203 can be driven to move along the annular ground rail 14 until they face the other two sides of the cargo a, thus taking pictures of those two sides.

[0066] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
