Description

Technical Field

[0001] The present invention relates to the technical field of telescopic forks, and more particularly to a medium-load rotating hook telescopic fork with visual calibration. Background Art

[0002] Medium-load rotary hook telescopic fork is a device used in automated warehousing and logistics systems, mainly used for the storage, handling and stacking of goods. Among them, the common medium-load rotary hook telescopic fork is mainly composed of a telescopic mechanism, a rotating mechanism, a transport plate, a drive system and a control system. The specific working process of the medium-load rotary hook telescopic fork is as follows: the control system uses the internal visual calibration module to locate the item in real time. After the positioning is completed, the drive system and the control system generate specified instructions. The rotating mechanism rotates the fork to the target angle according to the instruction, usually 180 degrees or 360 degrees, to align with the target goods; the telescopic mechanism telescopes the fork to the target length according to the instruction to adapt to the shelf depth and cargo size; the transport plate moves to the bottom of the cargo and lifts the cargo under the action of the drive system. After the cargo is lifted, the above steps are repeated to facilitate the positioning and transportation of the cargo.

[0003] During actual operation, we found that some transport plates were deformed during operation. In subsequent research, we found that the main reasons for this phenomenon were: 1. The transport plates were subjected to long-term overload handling, which caused wear between the connecting components of the transport plates, and thus caused the entire transport plate to deform; 2. Uneven load: The uneven distribution of goods on the forks caused local stress concentration, which accelerated the deformation and damage of the transport plates. When the above situation occurs, it may cause the goods to fall off during handling, thereby increasing safety risks. At the same time, the deformation of the transport plates will reduce the accuracy of their expansion and rotation, affecting the accurate positioning and access of goods. The above problems can only be discovered through manual quality inspection, which leads to a certain amount of manpower waste;

Two groups of the two groups of U-shaped telescopic plates 410 are respectively installed at the sides corresponding to the first hollow column 302 and the second hollow column 402, and one group of auxiliary support plates 403 and one group of U-shaped telescopic plates 410 close to the position of the second hollow column 402 can isolate the interior of the second hollow column 402 into two independent sealed spaces A. Similarly, another group of auxiliary support plates 403 and another group of U-shaped telescopic plates 410 can isolate the interior of the first hollow column 302 into two independent sealed spaces B.

[0050] Another set of auxiliary support plates 403 is installed on the other end of the transmission rod 301 at a position away from the first hollow column 302, and the geometric center point of the transmission rod 301 and the geometric center point of the other set of auxiliary support plates 403 are in a straight line;

[0053] The control system includes a threshold range generation module, a real-time status monitoring module and an alarm module;

[0054] Threshold range generation module: used to simulate the simulated pressure data generated by the pressure sensor 411 when the transport plate A102 is in a non-tilted, deformed state. The threshold range generation module calculates and integrates the simulated pressure data to generate a threshold range.

[0055] Real-time status monitoring module: used to compare the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that the surface of the transport plate A102 is tilted;

[0056] Alarm module: When receiving information that the surface of the transport plate A102 is tilted, the alarm module generates an early warning message and issues an early warning to the staff remotely.

[0057] In the embodiment of the present application, when the control system determines that the surface of the transport plate A102 is tilted, it controls the rotating device 2 and the auxiliary gripper 3 to temporarily process the phenomenon. After the processing is completed, the control system performs a secondary detection of the real-time state of the surface of the transport plate A102. If the transport plate A102 is still in a tilted state after the secondary detection, it is determined that the surface of the transport plate A102 is deformed. If the transport plate A102 is not in a tilted state, it is determined that the auxiliary transport plate 101, the transport plate A102 and a certain connection component of the telescopic fork 1 are excessively worn, which facilitates the staff to quickly determine the cause of the tilt of the transport plate A102.

[0058] The three sets of auxiliary delivery pipes B408 are each equipped with a solenoid valve to control the flow direction of the hydraulic oil on the inner wall of the hydraulic compartment A4001;

[0059] A torsion spring device is installed at one end of the movable support rod 409 to temporarily limit the movable support rod 409.

[0060] The specific working process of this embodiment of the application is as follows: when the surface of the transport plate A102 is tilted, the tilted side of the transport plate A102 drives the corresponding L-shaped plate 404 and a set of auxiliary support plates 403 to rotate at a corresponding angle. During the rotation, the internal volume of a set of sealed spaces A inside the second hollow column 402 changes accordingly. The pressure data collected by the pressure sensor 411 in the set of sealed spaces A also changes accordingly. The control system detects the change in data and determines that the corresponding side of the second hollow column 402 has deformed.

[0061] When the control system determines that one side of the second hollow column 402 is deformed, it controls the electrically controlled angle adjustment device 202 and the electrically controlled hydraulic column 203 to input a stable operating current, thereby driving the limit clamp 206 to move to the inner wall of the T-shaped plate 4, and the outer wall of the T-shaped plate 4 is clamped onto the inner wall of the limit clamp 206. When the two are in contact, the hollow pillar 401 contacts the surface of the first torsion spring plate 207 and drives the first torsion spring plate 207 to rotate a certain angle. At this time, the hydraulic chamber A4001 and the hydraulic chamber B inside the limit clamp 206 are in a state of mutual communication through the hollow pillar 401;

[0062] The hydraulic transmission device 204 inputs a stable working current, driving the hydraulic oil inside the hydraulic transmission device 204 to be input into a corresponding set of sealed spaces A through the auxiliary delivery pipe A205, the hollow pillar 401, the hydraulic compartment A4001 and the corresponding auxiliary delivery pipe B408. The hydraulic oil in the set of sealed spaces A is first transmitted to a set of sealed spaces B corresponding to the first hollow pillar 302 through the corresponding main delivery pipe 406, and then squeezes the auxiliary support plate 403 in the corresponding set of sealed spaces B, thereby driving the transmission rod 301 and the auxiliary gripper 3 to rotate a certain angle, thereby temporarily limiting the goods on the surface of the handling plate A102 in an inclined state, thereby preventing the goods from tipping over during transportation;

[0063] After the corresponding auxiliary gripper 3 rotates to a specified angle, the hydraulic oil in the corresponding sealed space A will drive the auxiliary support plate 403 inside it to rotate to a certain angle. During the rotation of the auxiliary support plate 403, the corresponding set of L-shaped plates 404 and the main support plate 405 will be driven to apply an additional supporting force to the inclined side of the transport plate A102, thereby achieving the effect of temporarily limiting the inclined side of the transport plate A102, avoiding the gradual increase in the inclination state of one side of the transport plate A102, and at the same time reducing the degree of wear of the connecting components between the auxiliary transport plate 101, the transport plate A102 and the telescopic fork 1, and to a certain extent, reducing the subsequent maintenance cost of the overall device.

[0064] The workflow of this application is:

[0065] Cargo handling: The control system controls the rotation device 2 to input a stable current, controls the mounting platform 201 and the telescopic fork 1 to rotate to a specified angle. After the angle adjustment of the telescopic fork 1 is completed, the control system controls the telescopic fork 1 to input a stable operating current, drives the auxiliary transport plate 101 and the transport plate A102 to extend and retract to the target length. At this time, the transport plate A102 is located at the bottom of the transported items. The telescopic fork 1 drives the transport plate A102 and the auxiliary transport plate 101 to a specified height, so that the transported items can be lifted off the specified ground and the transport plate A102 can carry the specified items.

[0066] Deformation detection: When the surface of the transport plate A102 tilts, the tilted side of the transport plate A102 drives the corresponding L-shaped plate 404 and a set of auxiliary support plates 403 to rotate at a corresponding angle. During the rotation, the internal volume of a set of sealed spaces A inside the second hollow column 402 changes accordingly. The pressure data collected by the pressure sensor 411 in the set of sealed spaces A also changes accordingly. The control system detects this change in data and determines that the corresponding side of the second hollow column 402 has deformed.

[0067] Temporary solution: When the control system determines that one side of the second hollow column 402 is deformed, it controls the electrically controlled angle adjustment device 202 and the electrically controlled hydraulic column 203 to input a stable operating current, thereby driving the limit clamp 206 to move to the inner wall of the T-shaped plate 4. The outer wall of the T-shaped plate 4 will be locked onto the inner wall of the limit clamp 206. When the two are in contact, the hollow pillar 401 will contact the surface of the first torsion spring plate 207 and drive the first torsion spring plate 207 to rotate a certain angle. At this time, the hydraulic chamber A4001 and the hydraulic chamber B inside the limit clamp 206 are in a state of mutual communication through the hollow pillar 401;

[0068] The hydraulic transmission device 204 inputs a stable working current, driving the hydraulic oil inside the hydraulic transmission device 204 to be input into a corresponding set of sealed spaces A through the auxiliary delivery pipe A205, the hollow pillar 401, the hydraulic compartment A4001 and the corresponding auxiliary delivery pipe B408. The hydraulic oil in the set of sealed spaces A is first transmitted to a set of sealed spaces B corresponding to the first hollow pillar 302 through the corresponding main delivery pipe 406, and then squeezes the auxiliary support plate 403 in the corresponding set of sealed spaces B, thereby driving the transmission rod 301 and the auxiliary gripper 3 to rotate a certain angle, thereby temporarily limiting the goods on the surface of the handling plate A102 in an inclined state, thereby preventing the goods from tipping over during transportation;

[0069] After the corresponding auxiliary gripper 3 rotates to a specified angle, the hydraulic oil in the corresponding sealed space A will drive the auxiliary support plate 403 inside it to rotate to a certain angle. During the rotation of the auxiliary support plate 403, the corresponding set of L-shaped plates 404 and the main support plate 405 will be driven to apply an additional supporting force to the inclined side of the transport plate A102, thereby achieving the effect of temporarily limiting the inclined side of the transport plate A102, avoiding the gradual increase in the inclination state of one side of the transport plate A102, and at the same time reducing the degree of wear of the connecting components between the auxiliary transport plate 101, the transport plate A102 and the telescopic fork 1, and to a certain extent, reducing the subsequent maintenance cost of the overall device.
