Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power supporting equipment, and specifically relates to an intelligent stacking and unstacking device. BACKGROUND

[0002] With the development of automation and intelligent technology, the logistics, warehousing and manufacturing industries have an increasing demand for efficient and accurate cargo handling equipment. In the field of power supporting, the delivery and storage of metering meters such as electricity meters require stacking and unstacking, and because intelligent metering meters have high precision, the stability and reliability of stacking and unstacking are required to be higher. Traditional stacking and unstacking operations usually rely on manual operation or simple mechanical equipment, which not only is inefficient and prone to errors, but also can lead to waste of labor resources and worker health problems in a repetitive and high-load work environment.

[0003] Although existing automatic stacking equipment improves work efficiency to some extent, it still has some shortcomings. For example, traditional automatic stacking machines can usually only handle specific sizes of turnover boxes, and have limited processing capacity for turnover boxes of different sizes, requiring equipment upgrades or pre-input parameters. In addition, these devices have insufficient positioning and handling accuracy for turnover boxes during stacking and unstacking, and sometimes require additional equipment or manual intervention to adjust the position of the goods, which increases the complexity and cost of the operation.

[0004] In addition, the existing stacking and unstacking equipment clamps the turnover box from the side of the turnover box, but considering the cost and recycling, most of the turnover boxes are paper boxes, and the strength of the paper box is not high, especially its rigidity and hardness. If the clamping force is insufficient, the paper box will fall or be unstable, and if the clamping force is too large, the paper box will be deformed and damaged. In addition, the weight and size of the goods loaded in the turnover box are not necessarily the same, and the thickness and strength of each paper box also differ, making it difficult to overcome this problem by pre-setting the clamping force.

[0015] The palletizing method of the intelligent palletizing and depalletizing device is as follows:

[0016] ①The dispersed turnover boxes are sequentially conveyed into the door opening, the second box body sensing device senses the presence of the turnover box, while the first box body sensing device does not sense the presence of the turnover box, the device automatically judges that the turnover box at this position is not in a stacked state, and triggers the palletizing action at the same time;

[0017] ②The vision system accurately identifies and calculates the specific position and shape and size of the turnover box; the controller controls the position and spacing of the second hydraulic telescopic rod adjusting sliding block to align with the turnover box;

[0018] ③The controller controls the third and fourth hydraulic telescopic rods to extend cooperatively, so that the parallel plate and the bent plate form an angle shape to clamp and extrude the side right angle of the turnover box, and stop extending when the pressure sensed by the pressure sensor on the non-slip pad reaches a preset threshold; in this process, the side right angle tip of the turnover box extrudes the flexible capsule, so that the flexible capsule covers the side right angle tip of the turnover box; then the external circuit applies an electric field to the current variable fluid through the electrode coating to convert it into a solid locked shape and a covering state;

[0019] ④After clamping is completed, the first hydraulic telescopic rod drives the upper sliding seat to rise, thereby driving the turnover box to rise synchronously; during the rising to the end section, the screw rod can be rotated under the driving of the stepping motor, so that the lower sliding seat does not rise with the upper sliding seat, until the turnover box rises to beyond the groove, the second box body sensing device cannot sense the turnover box, while the first box body sensing device still senses the turnover box, triggering the stepping motor to drive the support plate to turn out;

[0020] ⑤The control device controls the first hydraulic telescopic rod to slightly extend, so that the turnover box descends a small distance and the bottom of the turnover box is supported on the support plate; after the turnover box extrudes the support plate, the pressure sensor on the support plate is triggered to send a signal to the controller, and the controller receives the signal to control the third and fourth hydraulic telescopic rods to slightly shorten, so that the bendable clamping plate weakens the horizontal clamping force on the turnover box, avoiding long-term extrusion of the turnover box;

[0021] ⑥The next turnover box is conveyed into the door hole by the conveying line, the first hydraulic telescopic rod drives the upper slide and the lower slide to move downward at the same time, the third hydraulic telescopic rod and the fourth hydraulic telescopic rod are controlled to extend, so that the bendable clamping plate clamps the turnover box again; then the rotatable threaded rod is controlled to rotate, so that the lower slide moves downward, and the turnover box is separated from the extrusion support plate; after the pressure sensor on the support plate senses that the pressure is lost, the stepping motor is triggered to drive the support plate to rotate back into the groove;

[0022] ⑦The first hydraulic telescopic rod drives the upper slide and the lower slide to move downward until the clamped turnover box is stacked above the new turnover box entering the door hole; the third hydraulic telescopic rod and the fourth hydraulic telescopic rod are controlled to shorten, so that the clamping state is released, and the bending plate is bent back to be substantially in the same straight line with the parallel plate; the electric field applied to the electrorheological fluid is removed, so that it returns to a liquid state, thereby fully releasing the clamping state of the turnover box;

[0023] ⑧The conveying line moves the stacked turnover box out.

[0024] The intelligent stacking and unstacking device has the following unstacking method:

[0025] ①The conveying line conveys the turnover box of the stack into the door hole, the second box body sensing device senses the existence of the turnover box, and at the same time, the first box body sensing device also senses the existence of the turnover box, the device automatically judges that the turnover box at this position is in a stacked state, and simultaneously triggers the unstacking action;

[0026] ②The visual system accurately identifies and calculates the specific position, shape, and size of the uppermost turnover box; the controller controls the second hydraulic telescopic rod to adjust the position and distance of the sliding block to be aligned with the turnover box;

[0027] ③The controller controls the third hydraulic telescopic rod and the fourth hydraulic telescopic rod to extend cooperatively, so that the parallel plate and the bending plate form an angle shape to clamp and extrude the side right angle of the uppermost turnover box, and stop extending after the pressure sensed by the pressure sensor on the non-slip pad reaches a preset threshold value; in this process, the side right angle tip of the turnover box extrudes the flexible capsule, so that the flexible capsule covers the side right angle tip of the turnover box; then the external circuit applies an electric field to the electrorheological fluid through the electrode coating to convert it into a solid locked shape and a covering state;

[0028] ④After clamping is completed, the first hydraulic telescopic rod drives the upper slide to rise, thereby driving the turnover box to rise synchronously; during the rising to the end section, the rotatable threaded rod is rotated under the driving of the stepping motor, so that the lower slide does not rise with the upper slide; until the turnover box rises to beyond the groove, the second box body sensing device cannot sense the turnover box, while the first box body sensing device still senses the turnover box, triggering the stepping motor to drive the support plate to rotate out;

[0029] V. The control device controls the first hydraulic telescopic rod to slightly extend, causing the turnover box to descend a small distance and the bottom of the turnover box to be supported on the support plate; after the turnover box presses the support plate, the pressure sensor on the support plate is triggered, sending a signal to the controller, and after the controller receives the signal, the third hydraulic telescopic rod and the fourth hydraulic telescopic rod are controlled to slightly shorten, causing the horizontal clamping force of the bendable clamping plate on the turnover box to weaken, avoiding long-term pressing of the turnover box;

[0030] VI. The control device controls the first hydraulic telescopic rod to slightly extend, causing the turnover box to descend a small distance and the bottom of the turnover box to be supported on the support plate; after the turnover box presses the support plate, the pressure sensor on the support plate is triggered, sending a signal to the controller, and after the controller receives the signal, the third hydraulic telescopic rod and the fourth hydraulic telescopic rod are controlled to slightly shorten, causing the horizontal clamping force of the bendable clamping plate on the turnover box to weaken, avoiding long-term pressing of the turnover box;

[0031] VII. The control device controls the first hydraulic telescopic rod to extend again until the turnover box contacts the conveying line, and controls the third hydraulic telescopic rod and the fourth hydraulic telescopic rod to shorten, releasing the clamping state and causing the bending plate to bend back to be generally in the same straight line as the parallel plate; the electric field applied to the electrorheological fluid is removed, causing it to return to a liquid state, thereby fully releasing the clamping state of the turnover box;

[0032] VIII. The conveying line removes the disassembled turnover box.

[0033] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present application are:

[0034] 1. Overall, the intelligent stacking and unstacking device has the following advantages:

[0035] High efficiency and automated operation: The automated design of the device allows for quick and continuous stacking and unstacking operations, significantly improving operational efficiency and reducing the need for manual operation.

[0036] Precise clamping and positioning: Through advanced clamping mechanisms and box sensing devices, the device can accurately identify and position the turnover box, ensuring the accuracy of the operation.

[0037] Strong adaptability: The design of the device allows for automatic adjustment of the clamping mechanism, which can accommodate turnover boxes of different sizes, increasing the range and flexibility of the device.

[0038] Protective clamping design: The combination of the bending plate and the parallel plate with the flexible capsule and electrorheological fluid can apply appropriate force to the turnover box during clamping, reducing damage to the goods.

[0039] Intelligent sensing and vision system: The combination of infrared, laser, ultrasonic sensing devices and vision systems provides higher operational accuracy, reducing errors and potential operational risks.

[0040] Anti-slip and safety measures: The application of anti-slip mats and pressure sensors ensures the safety and stability of the operation, preventing the goods from slipping or being damaged during handling.

[0041] In summary, the intelligent stacking and unstacking device of the present application not only provides an efficient, accurate and safe material handling solution, but also improves the flexibility and user experience of the operation through intelligent technology and innovative design.

[0042] 2、The special clamping design for cartons has the following advantages:

[0043] Side right-angle clamping: The bending plate and parallel plate design is specifically used for clamping from the side right-angle of the carton (i.e. the strongest part). It is suitable for handling cartons with low strength and easy deformation, ensuring that the carton will not be deformed or damaged during clamping.

[0044] Self-adaptive clamping force: By utilizing the characteristics of flexible capsules and electrorheological fluid, the device can automatically adjust the clamping force according to the actual conditions of the carton (such as weight, thickness and internal load). This means that regardless of the specific specifications of the carton, the device can maintain stable and safe clamping; and through the characteristics of flexible capsules and electrorheological fluid in liquid state, it can provide a larger contact area and wrapping effect for the carton angle, reducing the clamping precision requirement, even if the clamping precision is slightly reduced, it can still achieve stable contact and wrapping of the carton angle; at the same time, after wrapping, it can instantly convert the electrorheological fluid into solid state, thereby achieving rigid clamping of the carton angle and avoiding the carton from falling off.

[0045] Reducing the risk of carton damage: Traditional side clamping of cartons often has the risk of insufficient or excessive clamping force, and the present application significantly reduces the risk of carton damage during handling by intelligently adjusting the clamping force.

[0046] Improving the reliability and safety of the operation: By precisely controlling the clamping force, the posture of the carton during handling is stable, improving the reliability and safety of the entire operation.

[0047] In addition, this innovative clamping method, combined with the aforementioned intelligent sensing and vision system, high efficiency and automated operation, provides a comprehensive, efficient, safe and friendly material handling solution for users. Especially for cartons, which are common but have low strength, the present application provides a better handling method, effectively overcoming the limitations of existing technologies.

[0048] 3、The design of the upper slide, clamping mechanism, lower slide and support plate in the intelligent stacking and unstacking device of the present application brings precise coordination and multiple benefits to the stacking and unstacking process:

[0049] The action of the upper slide and the clamping mechanism

[0050] Precise positioning and clamping: The clamping mechanism on the upper slide can be precisely adjusted according to the size and position of the toter through the horizontal rail and slider design. This design allows the clamping mechanism to align with the toter's side at a right angle, ensuring the accuracy of the clamping position.

[0051] Adaptive clamping: The bending design of the clamping plate and the application of electrorheological fluid allow the clamping force to automatically adjust according to the material and loading conditions of the toter, preventing excessive pressure on the carton that could cause damage. The design of the bending plate and the parallel plate can be used to clamp the carton at a right angle, and can also be expanded to make the bending plate and the parallel plate close to a straight line, facilitating the removal of the carton and preventing obstruction, thus achieving both the right-angle clamping scheme.

[0052] The role of the lower slide and the support plate

[0053] Stable support: The support plate on the lower slide can be extended when needed to provide bottom support for the toter, converting the side clamping support relying on friction into bottom support, thereby reducing the clamping time of the clamping mechanism on the carton, reducing the possibility of carton deformation, and reducing the occurrence of unstable carton posture.

[0054] Precise control: The support plate is driven by a stepper motor, which can accurately control its rotation and position, ensuring timely support when the toter is lowered.

[0055] Improved work efficiency: The coordinated operation of the upper and lower slides greatly improves the speed and efficiency of stacking and unstacking.

[0056] Reduced damage to goods: Precise clamping and support reduce the risk of damage to the toter during handling.

[0057] Improved work safety: Stable clamping and support ensure the safety of the entire stacking and unstacking process, especially for heavy or irregularly shaped toters.

[0058] Adapt to various types of toters: This design allows the device to adapt to toters of different sizes, shapes, and materials, improving the flexibility and applicability of the device.

[0059] Overall, the coordinated operation of the upper slide and clamping mechanism, the lower slide and support plate, brings high efficiency, high precision, and high safety to the intelligent stacking and unstacking device, while also improving the device's adaptability to different types of toters.

[0095] ⑦The control device controls the first hydraulic telescopic rod 54 to extend again until the turnover box 3 contacts the conveying line 4, controls the third hydraulic telescopic rod 69 and the fourth hydraulic telescopic rod 68 to shorten, releases the clamping state, and makes the bent plate 67 bend back to be generally in the same straight line with the parallel plate 66; the electric field applied to the electrorheological fluid 71 is released, so that it returns to a liquid state, thereby completely releasing the clamping state on the turnover box 3;
