[0001] The utility model relates to an RGV device for transporting and handling materials. Background Art
[0002] In the fields of automation equipment, mechanical engineering, and logistics equipment, etc., a roller-type RGV device (Rail Guided Vehicle) is a common device, mainly used for transporting and handling materials.
[0003] The current common disadvantages of the roller-type RGV device are as follows: First, the track width in the roller mechanism is fixed. When transporting materials through the rotation of the rollers, if the size of the material is smaller than the track width, stable transportation cannot be achieved due to lack of guidance. Therefore, usually only materials of a single specification can be processed, resulting in poor versatility and low device usage efficiency. Second, the roller mechanism rotates at a certain angle through a rotating mechanism to achieve the docking of the roller mechanism with tracks in different directions for material transportation. However, there is no positioning after the rotation between the rotating mechanism and the walking vehicle body. Therefore, the rotation accuracy and mechanism stability of the rotating mechanism are poor, resulting in easy deviation of the position when the RGV device docks with tracks in different directions, and the rollers are prone to shaking when transporting materials.

[0025] When the variable-track motor 100 works, it drives the connecting shaft 102 to rotate through the coupling 101, so that the chain unit drives the variable track 104 to move back and forth along the guiding shaft 103, thereby changing the actual use width of the roller 12. The roller mechanism of the present utility model accommodates materials of different specifications by changing the actual use width of the roller 12, that is, changing the track width of the roller mechanism, and then conveys materials of different specifications.

[0029] When the variable-track motor 100 works, it drives the connecting shaft 102 and the driving sprocket 105 thereon to rotate through the coupling 101, thereby dragging the variable track 104 to move back and forth along the guiding shaft 103 through the chain 107, and changing the actual use length of the roller 12.
[0030] Embodiment 3
[0031] From Figure 1 、 Figure 3 It can be seen that for a variable-track roller mechanism of the present utility model: the variable-track assembly 10 further includes a variable-track sensor 110, and the variable-track sensor 110 is fixed at the rear end of the variable track 104.
[0032] The distance between the variable track 104 and the rear support plate of the roller frame 14 is measured by the variable-track sensor 110 to meet the dimensional requirements after the track change.
[0033] Embodiment 4
[0034] From Figure 1 、 Figure 2 、 Figure 3 It can be seen that for a variable-track roller mechanism of the present utility model: the variable-track assembly 10 further includes two protective covers 111 on the left and right, and the protective covers 111 are sleeved outside the coupling 101 and the connecting shaft 102.
[0035] The protective covers 111 play a protective role for the coupling 101 and the connecting shaft 102.
[0036] Embodiment 5
[0037] From Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 It can be seen that a rotatable roller RGV device with variable tracks of the present utility model includes a traveling vehicle body 3, a rotating mechanism 4, and a variable-track roller mechanism 1. The rotating mechanism 4 includes a roller support 41 at the upper part, a base 42 at the lower part, and a slewing bearing 43 in the middle. The roller support 41 is connected to the base 42 through the slewing bearing 43. The base 42 is fixed on the traveling vehicle body 3, and the variable-track roller mechanism 1 is fixed on the roller support 41. It further includes a locking mechanism arranged between the traveling vehicle body 3 and the rotating mechanism 4. The locking mechanism includes a locking motor 21, a connecting rod I 22, a connecting rod II 23, a locking rod 24, and three locking blocks 25. The locking blocks 25 are fixed on the traveling vehicle body 3, the locking motor 21 is fixed under the upper panel of the roller support 41. The upper part of the connecting rod I 22 is connected to the output shaft of the locking motor 21.

[0038] The roller support 41 rotates relative to the base 42 through the slewing bearing 43, thereby enabling the variable-rail roller mechanism 1 to rotate relative to the walking vehicle body 3.

At this time, the variable-rail roller mechanism works to transfer parts; after the part transfer is completed, the locking motor 21 operates in the reverse direction to move the locking rod 24 upward, separating the lower part of the locking rod 24 from the upper part of the locking block 25. At this time, the rotating mechanism 4 can drive the variable-rail roller mechanism 1 to rotate again.
[0039] After the rotating mechanism 4 drives the variable-rail roller mechanism 1 to rotate to a predetermined position, the rotating mechanism is locked by the locking mechanism, thereby fixing the position of the variable-rail roller mechanism 1 relative to the walking vehicle body 3, ensuring the rotation accuracy of the rotating mechanism and the stability of the mechanism, enabling the RGV device to reliably dock with tracks in different directions, and ensuring the stability of the roller conveying material process. Among them, the locking component can be started automatically or manually when needed.

[0042] The guiding sleeve 27 provides guidance for the up and down movement of the locking rod 24, ensuring stability.
[0043] Embodiment 7
[0044] From Figure 5 、 Figure 8 、 Figure 9 It can be seen that for a rotatable roller RGV device with variable rails of the present utility model: the upper part of the locking block 25 is concave, with inclined surfaces on both sides and a flat surface in the middle; the lower part of the locking rod 24 is convex, with a flat surface in the middle and inclined surfaces on both sides.
[0045] The protruding part of the locking rod 24 is locked by inserting into the concave part of the locking block 25, and vice versa for loosening; the inclined surfaces facilitate guiding, and the flat surface facilitates pressing.
[0046] The working principle of a rotatable roller RGV device with track-changing of the present utility model is as follows: The walking vehicle body 3 drives the whole device to move; the rotating mechanism 4 is used to change the relative position between the track-changing roller mechanism 1 and the walking vehicle body 3 to achieve multi-point docking.
