Description

Technical Field

[0001] The present invention relates to the technical field of automatic weighing equipment, in particular to a device for automatically moving and weighing packages, and a method for weighing and recording packages using the device. Background Art

[0002] Common packages weigh less than 500 kilograms. During storage, the weight of the packages needs to be recorded. Existing statistical recording methods include manual recording or auxiliary equipment tools. However, these recording methods require manual operation, so operational errors are inevitable.

[0003] Furthermore, taking the entire manual weighing process as an example, it requires the coordination of at least six people to move, transport, weigh, and measure the packages. Furthermore, manual operation is subject to significant errors and is labor-intensive. For example, using auxiliary equipment such as transport trucks, packages are typically quite tall, so they need to be lowered and raised repeatedly during movement, a process that requires manual operation. Conventional lifting equipment cannot measure their weight, and even if they can monitor the weight, it is difficult to record and correlate the measurement with the package. If the measurement data for one package is incorrect, all packages must be re-measured.

[0004] In combination with existing technologies such as image recognition technology and automatic control systems, further improvements need to be made to the existing package weighing and recording processes. Summary of the Invention

DETAILED DESCRIPTION

[0033] Combine Figures 1 to 7 As shown, the specific implementation of a self-moving piece-pack intelligent weighing system and a package weight statistics method provided by the present invention is described.

[0034] The specific structure of a self-moving piece-loaded intelligent weighing system includes a self-moving locomotive 1, a fixed turntable 2, a lifting cantilever 3, a wire rope motor 4, an electronic crane scale 5, a camera 6, a package moving mechanism 7, a lifting clamp 8, a barcode printer 9, a code sticking mechanism 10, a display 11 and a controller 12, wherein the various components of the weighing system are controlled by the controller, the self-moving locomotive 1 controls its free movement, the fixed turntable 2, the lifting cantilever 3 and the wire rope motor 4 work together to realize the lifting of the package, the camera 6 determines the actual position of the package, and determines the operation of the package moving mechanism and the code sticking mechanism through image recognition, the display 11 displays various information of the package, and the various components of the system are coordinated and controlled together, which can conveniently complete the moving, weighing, moving, coding and recording of the package, and the operation is more flexible. The combination with image recognition technology improves the level of automation, and further can realize fully automated operation.

[0035] The self-propelled locomotive 1 includes a base, drive wheels, and guide wheels. The drive wheels and guide wheels are arranged below the base. The drive wheels are driven by a motor, and the guide wheels are arranged in front of the moving direction of the self-propelled locomotive, thereby controlling the moving direction of the self-propelled locomotive. To ensure stability during lifting, brake devices can be installed on the running wheels and guide wheels to ensure that the running mechanism can cooperate with the lifting mechanism. To ensure the safety of the equipment, anti-collision guardrails can be installed around the base. This design can also increase the weight of the base, thereby further ensuring the stability of the lifting. In addition, a universal wheel movable plate can be installed at the bottom of the base, and a hydraulic cylinder can be installed between the drive wheel and the guide wheel. When the self-propelled locomotive does not need to move, it can be retracted so that the base directly falls to the ground and is fixed, which can ensure the stability of the lifting.

[0036] The fixed turntable 2 is fixedly mounted on the base, and the fixed turntable 2 can rotate relative to the base, so that it can be hoisted from different directions. The lifting cantilever 3 is fixedly connected to the fixed turntable 2, and the connection can be a plug-in method, a welding method, or other convenient installation structure; further, the lifting cantilever 3 can be a telescopic structure, which can be stored above the base after completion, thereby ensuring its safety. The wire rope motor is fixed on the lifting cantilever, and the wire rope motor can be connected to the electronic crane scale through the suspension rope. A lifting clamp is provided under the electronic crane scale 5, and the suspension rope can be controlled by the wire rope motor 4 to achieve lifting. After lifting, it is ensured that the package is more than 5 cm from the ground, and the distance from the ground does not need to be too large. Too large a distance from the ground can easily cause the package to shake. Maintaining a height of about 5 cm can ensure good measurement and make it more stable. A package moving mechanism is also provided on the base, which moves and separates the packages that are tightly attached side by side, thereby facilitating the clamping of the packages. The electronic crane scale 5 transmits weight measurement parameters to a barcode printer. The barcode affixing mechanism 10 pushes the printed barcode onto the package and affixes it. The display can show the package's image and weight information. The self-propelled locomotive 1, fixed turntable 2, wire rope motor 3, camera 6, package transfer mechanism 7, barcode printer 9, barcode affixing mechanism 10, and display 11 are all connected to a controller, which controls the operation of each component.

[0037] The package moving mechanism 7 may include a first cross arm 14, a second cross arm 15, a telescopic control motor 16 and a translation control motor 17. The first cross arm 14 and the second cross arm 15 are installed parallel to each other on the base. The telescopic control motor 16 controls the telescopic movement of the first cross arm and the second cross arm, and the translation control motor 17 controls the distance between the first cross arm and the second cross arm. Specifically, the relative distance between the first cross arm 14 and the second cross arm 15 may be controlled by a screw structure. The front ends of the first cross arm 14 and the second cross arm 15 are provided with a shifting spacer, which is inserted into the gap between the packages during the process of controlling the movement of the cross arm. In addition, both the first cross arm and the second cross arm can be telescopic. When the first cross arm 14 or the second cross arm 15 is contracted, the packages can be moved. If the first cross arm and the second cross arm are contracted alternately, the package can be moved.

[0038] The barcode application mechanism 10 may include a telescopic rod 18, a barcode application plate 19, and a self-priming pump 20. The barcode application plate 19 is disposed at the front end of the telescopic rod. A through-hole is provided on the barcode application plate and is connected to the middle hole of the telescopic rod. The self-priming pump is connected to the middle hole of the telescopic rod. The self-priming pump draws air, thereby adsorbing the barcode on the barcode application plate. The telescopic rod 18 is extended to affix the barcode application plate to the package. The self-priming pump is then stopped, and the telescopic rod 18 and barcode application plate 19 are retracted, and the printed barcode is affixed to the package.

[0039] Camera 6 can transmit images of the packages to the controller, either via wired or wireless data transmission. Controller 12 recognizes the images of the packages, specifically identifying the contact surfaces between the packages and the distance between camera 6 and the packages. Based on the location of the contact surfaces, the controller determines the extension length of the crossbar, precisely inserting the crossbar's spacer between the packages. Camera 6 is secured to the base via a mounting bracket, which controls the camera's height and rotation angle. Specifically, a mechanical wall can be provided to facilitate camera placement. Camera 6 transmits package image information to the controller via wireless signals, thereby enabling the correlation between package image information and weight information.

[0040] The lifting clamp 8 may specifically include a first clamping portion 21 and a second clamping portion 22, wherein the first clamping portion 21 and the second clamping portion 22 are hingedly fixed. The clamping end of the first clamping portion 21 is provided with a first clamping piece, and a spring is provided between the first clamping piece and the first clamping portion. The clamping end of the second clamping portion is provided with a second clamping piece, and a spring is provided between the second clamping piece and the second clamping portion. The first clamping piece and the first clamping portion may be fixed by a hinge, and the second clamping piece and the second clamping portion may also be fixed by a hinge.

[0041] In addition, the lifting clamp can be improved to include a first clamping part, a second clamping part, a third clamping part, and a fourth clamping part. The multiple clamping parts work together to clamp and fix the package. The middle part of the first clamping part and the middle part of the second clamping part can be fixed by a hinge, and the middle part of the third clamping part and the middle part of the fourth clamping part are fixed by a hinge. The clamping parts and the lifting clamp can be connected by a rope or chain. After lifting, the rope or chain is tightened, thereby pulling the clamping ends of the first and second clamping parts to clamp the package, ensuring the safety of lifting. The first and third clamping parts are arranged perpendicular to each other, and the second and fourth clamping parts are arranged perpendicular to each other; thus, the package can be clamped from two directions separately, ensuring the safety of lifting. To accommodate wider packages, the first and third clamping parts can be arranged in parallel, and the second and fourth clamping parts can be arranged in parallel. This allows the package to be clamped in the same direction with two lifting clamps, avoiding shaking of the package due to uneven clamping.

[0042] In another variation of this embodiment, to achieve clamping of cylindrical packages, the lifting clamp 8 may also include an annular clamping portion 23 and a telescopic connection end 24. The telescopic connection end 24 is connected to a hook below the electronic crane scale. The annular clamping portion contracts upon receiving tension from the telescopic connection end to clamp the package. The annular clamping portion is a telescopic ring, and the telescopic connection end is connected to the annular clamping portion. The telescopic connection end adjusts the expansion and contraction of the annular clamping portion, thereby achieving a more stable clamping of cylindrical packages, or packages of other shapes, without causing the packages to wobble.

[0043] The barcode printer 9 receives the measurement parameters of the electronic crane scale 5 in real time. After the electronic crane scale 5 weighs, the barcode printing outlet of the barcode printer is connected to the code sticking disk. The code sticking disk 19 absorbs the printed barcode, and the telescopic rod controls the code sticking disk to stick the printed barcode on the package. The fixed turntable is fixed to the base through an electric rotating shaft sleeve, and the self-propelled locomotive 1 is equipped with a charging power supply. A counterweight is installed on the lifting boom, and the lifting boom is a hydraulic telescopic structure, which can ensure that packages in multiple directions and multiple positions can be lifted. A fixed pulley is also provided on the lifting boom 3 to facilitate the operation of the suspension rope. A movable pulley is also provided between the suspension rope and the electronic crane scale, and the operation of the suspension rope is controlled by an electric motor.

[0044] A method for calculating the weight of a package, using the aforementioned self-propelled intelligent weighing system, comprises the following steps:

[0045] S1. Determine the current position and target position of the package, and control the self-propelled locomotive to move to the front of the current position of the package.

[0046] Packages are typically neatly arranged on the ground, placed close together. Packages typically weigh less than 500 kg. The base of a self-propelled trolley is typically 100 x 150 x 350 cm and weighs approximately 800 kg. The trolley is positioned so that packages can be easily moved from their current location to their target location, within the lifting range of the lifting boom.

[0047] S2. The camera adjusts its height and angle, transmitting images of the package to the controller, which determines the package's contact surface and distance. The controller has image recognition capabilities and can be trained to identify the package's size and contact surface, allowing it to accurately determine the package's contact surface during use.

[0048] S3. The first and second transverse arms of the package moving mechanism extend until their ends are flush with the contact surface of the package, adjust the distance between the first and second transverse arms to clamp the package, and control the first and second transverse arms to move the package.

[0049] The specific process may be that due to the heavy weight of the package, manual movement is relatively difficult and labor-intensive; the package moving mechanism moves the package by alternately contracting the first cross arm and the second cross arm. After the package is moved, the position of the package is determined again by image recognition, and the distance between the first cross arm and the second cross arm is adjusted to continue to increase, and then the first cross arm and the second cross arm are contracted to the base, and the package movement is realized in this reciprocating manner.

[0050] S4. Adjust the fixed turntable and the lifting cantilever to rotate them above the moved package, lower the lifting clamp, and after the lifting clamp clamps the package, control the wire rope motor to lift it.

[0051] S5. After the package is lifted, the electronic crane scale measures the weight of the package. The weight information of the package is transmitted to the barcode printer and controller, and the display shows the image information and weight information of the package.

[0052] S6. The coding mechanism controls the telescopic rod and the coding tray to apply the printed barcode to the package. Specifically, the self-priming pump of the coding mechanism opens when the printed barcode is delivered to the coding tray, and the printed barcode is adsorbed on the coding tray. After the telescopic rod is extended and the coding tray is applied to the package, the self-priming pump stops, and the printed barcode is applied to the package. The telescopic rod then retracts.

[0053] S7. The fixed turntable and the lifting arm continue to rotate to deliver the package to the target location, thereby completing the movement and weighing of the package.

[0054] S8. The controller records the weight and image information of the package. The controller may also upload the weight and image information to a cloud-based data database or a blockchain IoT information platform.

[0055] The system can also realize the automatic operation of packaging, improve work efficiency, and further utilize the system to weigh and measure packaging. The weighing working method is more reasonable, and it also has the advantages of simple operation and high degree of automation.

[0056] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
