Description

Technical Field

[0001] This application relates to the field of cargo calibration technology, and in particular to a high-speed machine plate fork cargo calibration device. Background Technology

[0002] High-speed bin handling machines operate within the aisles of automated warehouses, responsible for retrieving and storing bins between aisle entrances and racking compartments. Their core components include a lifting platform and pallet forks: the pallet forks are mounted on the lifting platform and can slide horizontally relative to the platform along their length. When retrieving or placing goods, the pallet forks first extend from the lifting platform. After external handling equipment transfers the bin to the pallet forks, the forks retract back onto the lifting platform, carrying the bin. Subsequently, the entire lifting platform rises and falls, transporting the bin to the target storage location or aisle entrance.

[0003] Because some box-shaped goods are relatively light, they are easily displaced by airflow disturbances or inertial forces during high-speed operation, causing the boxes to deviate from their intended positions and affecting subsequent positioning accuracy and operational safety.

[0022] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0023] This application discloses a high-speed machine plate fork cargo correction device.

[0024] Example 1 A high-speed pallet fork cargo straightening device includes a lifting platform 1, a mounting frame 2, and clamping plates 3. Pallet forks 12 are mounted on the lifting platform 1, and the pallet forks 12 and the lifting platform 1 slide along the length of the pallet forks 12. The mounting frame 2 is fixedly mounted on the lifting platform 1, and the clamping plates 3 are mounted on the mounting frame 2. A pair of clamping plates 3 are provided, and the distance between the two clamping plates 3 is adjustable.

[0025] When the goods 13 are placed on the pallet fork 12, the pallet fork 12 extends out of the lifting platform 1 first. After the handling equipment places the goods 13 on the pallet fork 12, the pallet fork 12 retracts back onto the lifting platform 1, and the two clamping plates 3 move toward the goods 13 on the pallet fork 12 together and clamp the goods 13. This makes it easier for the goods 13 on the pallet fork 12 to be in a predetermined position, such as the center position in the width direction of the pallet fork 12 or other positions, so that the subsequent handling equipment can accurately handle the goods 13. At the same time, by clamping the goods 13 with the two clamping plates 3, the goods 13 is limited, so that the goods 13 may be deviated in position when the lifting platform 1 moves synchronously with the goods 13.

[0026] Each clamping plate 3 is driven by an independent linear driver 4, and the linear driver 4 is equipped with a measuring device for measuring the torque of the output shaft of the linear driver 4.

[0027] Since the clamping plate 3 moves via an independent linear drive 4, its installation position can be adjusted according to actual conditions, facilitating its later installation on the lifting platform 1. Furthermore, because the clamping plate 3 is driven by an independent linear drive 4, its travel distance can be set individually to adjust the position of the cargo 13 on the forks 12.

[0028] When the goods 13 are placed on the pallet fork 12, the handling equipment will generally place the goods 13 in the predetermined position. The two clamping plates 3 mainly serve to clamp the goods 13. However, when the handling equipment places the goods 13 on the pallet fork 12, sometimes the placement position of the goods 13 deviates from the predetermined position. When the clamping plates 3 clamp the goods 13, they need to push the goods 13 to the predetermined position. At this time, the torque of the linear actuator 4 that drives the clamping plates 3 to move will be relatively large. When the torque of a single linear actuator 4 is relatively large for a long time, it means that the position of the goods 13 placed on the pallet fork 12 has deviated, and the operator needs to adjust the handling equipment.

[0029] The two clamping plates 3 have mounting grooves 31 along the length of the clamping plates 3 on the side that is far apart from each other, and each clamping plate 3 is provided with a guide plate that blocks the mounting grooves 31.

[0030] A guide seat 5 is fixedly installed on the mounting bracket 2. A guide rod 6 passes through the guide seat 5. The guide rod 6 slides with the guide seat 5 in a direction perpendicular to the clamping plate 3. One end of the guide rod 6 is placed inside the mounting groove 31 and is fixedly connected to the inner wall of the mounting groove 31 through the first connector 61.

[0031] To improve the accuracy of the movement position of the clamping plate 3, a guide seat 5 with a guide rod 6 is installed near each end of the clamping plate 3.

[0032] The first connector 61 includes a first nut 611, a second nut 612, and an annular washer 613. The first nut 611 and the second nut 612 are both threaded onto the guide rod 6. The mounting groove 31 is a T-shaped groove, and the first nut 611 slides into the mounting groove 31 through the end of the mounting groove 31.

[0033] An annular washer 613 is fitted onto the guide rod 6, and a second nut 612 presses the annular washer 613 against the outer wall of the mounting groove 31. Subsequently, multiple second nuts 612 are provided. Through the coordinated cooperation of multiple second nuts 612, the stability of the guide rod 6 installed on the clamping plate 3 is improved.

[0034] Since the guide plate 32 blocks the mounting groove 31, the possibility of the first nut 611 causing the guide rod 6 to slide out of the mounting groove 31 is reduced.

[0035] The guide plate 32 is an arc-shaped plate. The distance between the guide plates 32 at the adjacent ends of the two clamping plates 3 gradually increases in the direction from near the clamping plate 3 to far away from the clamping plate 3. When the plate fork 12 is retracted from the state of being extended from the lifting platform 1, the cargo 13 may deviate. When the cargo 13 comes into contact with the guide plate 32, the guide plate 32 initially guides the cargo 13, so that the cargo 13 is close to the center position in the width direction of the plate fork 12.

[0036] The guide plate 32 has a T-shaped connecting block 321 at its end. The T-shaped connecting block 321 and the T-shaped mounting groove 31 are inserted into each other. The connecting block 321 is detachably fixed to the inner wall of the mounting groove 31 by bolts. The connecting block 321 is inserted into the mounting groove 31, which facilitates the installation of the guide plate 32 on the clamping plate 3. At the same time, the connecting block 321 seals the end of the mounting groove 31, reducing the possibility of the first nut 611 slipping out of the mounting groove 31.

[0037] An L-shaped second connector 41 is provided between the push rod of the linear actuator 4 and the clamping plate 3. The second connector 41 includes a first connecting plate 411 and a second connecting plate 412. The first connecting plate 411 is connected to the push rod of the linear actuator 4, and the second connecting plate 412 is connected to the clamping plate 3.

[0038] The second connecting plate 412 and the clamping plate 3 have a relatively large contact area, which improves the uniformity and stability of the force on the clamping plate 3.

[0039] In this embodiment, the linear driver 4 is a servo motor, and the servo motor is equipped with a servo controller. The servo controller controls the operation of the servo motor and monitors the working torque of the servo motor to determine the force on the clamping plate 3, and then determines whether the cargo 13 has shifted.

[0040] The lifting platform 1 has multiple uprights 11 fixedly installed on it. The mounting frame 2 includes a longitudinal plate 21 and a transverse plate 22. The longitudinal plate 21 is perpendicular to the vertical plane, and the end of the longitudinal plate 21 is fixedly connected to the adjacent upright 11. The transverse plate 22 is fixedly installed on the longitudinal plate 21. The guide seat 5 is fixedly installed on the longitudinal plate 21, and the height of the guide seat 5 is adjustable. The linear driver 4 is fixedly installed on the transverse plate 22. The bottom of the linear driver 4 is fixedly installed with a mounting plate 42. The mounting plate 42 is provided with a waist groove, and the waist groove is provided with a bolt and nut assembly to facilitate the adjustment of the horizontal position of the linear driver 4, thereby facilitating the adjustment of the initial position of the clamping plate 3.

[0041] An L-shaped adjusting member 51 is provided between the guide seat 5 and the longitudinal plate 21. The adjusting member 51 includes a first adjusting plate 511 and a second adjusting plate 512. The first adjusting plate 511 has a groove along the vertical direction, and an adjusting bolt that passes through the longitudinal plate 21 is provided at the groove. A nut is threaded onto the adjusting bolt.

[0042] The height of the guide seat 5 is finely adjusted by sliding the adjusting bolt inside the groove, so that the guide rod 6 can adapt to the position of the clamping plate 3. After the guide rod 6 is in the predetermined height position, the first adjusting plate 511 is fixed to the longitudinal plate 21 by the cooperation of the nut and the adjusting bolt.

[0043] The implementation principle of the high-speed pallet fork cargo correction device in Embodiment 1 of this application is as follows: The lifting platform 1 first drives the pallet fork 12 to extend along the length direction of the pallet fork 12. The handling equipment places the cargo 13 on the pallet fork 12. Then the pallet fork 12 retracts to the lifting platform 1. Two clamping plates 3 driven by independent servo motors move closer to the cargo 13 in coordination under the guidance of their respective guide rods 6 and guide seats 5. The arc-shaped guide plate initially guides the cargo 13 that has deviated from its position and pushes it to a predetermined position in the width direction of the pallet fork 12. The servo motor monitors the output torque in real time to determine whether the cargo 13 has deviated. The lifting platform 1 carries the cargo 13 synchronously while the clamping plates 3 continuously clamp the cargo 13, thereby completing the precise positioning and stable transportation of the cargo 13.

[0044] Example 2 The horizontal plate 22 is provided with a insertion groove 221 on the side near the vertical plate 21, which is inserted into the vertical plate 21. A locking bolt is threaded on the groove wall of the insertion groove 221. The end of the locking bolt abuts against the vertical plate 21. The position of the clamping plate 3 along the length direction of the clamping plate 3 is adjusted by sliding the insertion groove 221 on the vertical plate 21.

[0045] Multiple reinforcing plates 222 are provided on the outer walls of the horizontal plate 22 and the insertion slot 221 to improve the stability of the horizontal plate 22 supporting the linear actuator 4. The width of the vertical plate 21 gradually increases from top to bottom, and the width of the insertion slot 221 is adapted to the vertical plate 21 to further improve the structural strength of the vertical plate 21 and reduce the possibility of deformation of the vertical plate 21. The position where the guide seat 5 is connected on the vertical plate 21 is still a vertical plane for easy connection.

[0046] The implementation principle of the high-speed pallet fork cargo correction device in Embodiment 2 of this application is as follows: the horizontal plate 22 slides on the vertical plate 21 through the insertion groove 221 and is fixed by the locking bolt, so as to realize the position adjustment of the clamping plate 3 along the length direction of the clamping plate 3. The horizontal plate 22 and the multiple reinforcing plates 222 on the outer wall of the insertion groove 221 jointly improve the stability of the horizontal plate 22 supporting the linear actuator 4. At the same time, the width of the vertical plate 21 gradually increases from top to bottom and is adapted to the width of the insertion groove 221, further enhancing the structural strength of the vertical plate 21 and reducing the possibility of deformation of the vertical plate 21.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
