The AGV trolley transportation system comprises a plurality of AGV trolleys, guide bars 2 and a plurality of landmarks 3, wherein each AGV trolley 1 comprises a frame 11 and a functional assembly arranged on the frame 11, each functional assembly comprises a lifting rod 12, a guide bar sensor 13 and a landmark sensor 14, each AGV trolley 1 is used for transporting a material 9, each guide bar 2 is arranged on the ground to limit the moving track of each AGV trolley 1, the landmarks 3 are arranged at intervals along the moving tracks, the number of the landmarks 3 is matched with that of the AGV trolleys 1, and the distance between every two adjacent landmarks 3 is matched with the size of the material 9.

It can be understood that the conventional AGV carts 1 usually run independently, and the normal running mode is that one AGV cart 1 carries one piece of material 9 from point a to point B, and in this process, if another AGV cart 1 also needs to carry another piece of material 9 from point a to point B, it needs to wait for the previous AGV cart 1 to leave point a and then move to point a, and then wait for the previous AGV cart 1 to leave point B and then move to point B. The operation mode is point-to-point operation, only one material 9 can exist in one point, and the carrying efficiency is low.

The running mode of synchronous motion of a plurality of AGV dollies 1 appears in the prior art, namely a plurality of AGV dollies 1 exist simultaneously in point A, and a plurality of AGV dollies 1 are unified to be moved to point B by point A. The operation mode enables a plurality of materials 9 to exist in one point position, and the carrying efficiency is improved.

However, in order to avoid collision between the materials 9, the conventional scheme needs to reserve a wider safety distance between the AGV carts 1, so that the number of the AGV carts 1 in a unit space is reduced, and the density of the materials 9 in the unit space is reduced.

According to the AGV trolley transportation system provided by the utility model, the plurality of AGV trolleys 1 synchronously transport the materials 9, the AGV trolleys 1 are positioned according to the landmarks 3, and the landmarks 3 are arranged to accurately adjust the distance between the AGV trolleys 1, so that the number of the AGV trolleys 1 which can be accommodated in a unit space is increased, and the transportation efficiency of the AGV trolleys 1 is further improved.

Specifically, the landmarks 3 may be disposed at various positions of the moving track, such as the point a, or may be disposed at a special calibration point, and the AGV carts 1 are parked and positioned at intervals according to the landmarks 3, so as to determine the spacing of the AGV carts 1. Referring to fig. 1, when the AGV trolley transportation system is used for transporting materials 9, the distance between the AGV trolleys 1 is calibrated and adjusted through the landmark 3, and the AGV trolleys 1 perform synchronous motion after calibration, so that the distance between the AGV trolleys 1 can be reduced while collision is avoided.

The conducting bar 2 may be a magnetic strip, and the conducting bar sensor 13 determines the moving track by detecting the magnetic field. The interaction between the bar 2 and the bar sensor 13 can also be realized in other ways.

According to some embodiments of the utility model, the various parts of the functional assembly are laid flat on the frame 11. The tiling setting means that each part that the functional module contained does not adopt the mode setting of stacking, but roughly the tiling is in the same layer of frame 11, and the tiling setting can reduce AGV dolly 1's height as far as possible for AGV dolly 1 can be applicable to the lower material 9 in bottom such as transportation spinning cake car.

In some embodiments, the functional components include a first material sensor 15, the first material sensor 15 being used to detect whether the AGV car 1 is in place. The first material sensor 15 responds to the position of the material 9, and the lifting rod 12 rises according to a signal fed back by the first material sensor 15, so that the lifting rod 12 can hang the material 9 at a proper position. For example, in a scenario of transporting a spinning cake car, referring to fig. 1, the lifting rod 12 is hooked on a side wall of the spinning cake car to drive the spinning cake car to move, the first material sensor 15 may use an infrared sensor, and when the first material sensor 15 leaves from below the spinning cake car, the lifting rod 12 is controlled to ascend to be hooked on the side wall of the spinning cake car.

In some embodiments, the functional components include a second material sensor 16, the second material sensor 16 being located behind the first material sensor 15, the second material sensor 16 being used to detect whether the AGV car 1 is carrying material 9. The rear direction is the direction opposite to the moving direction of the AGV trolley 1, if the second material sensor 16 cannot detect the material 9, it indicates that the AGV trolley 1 cannot successfully hang the material 9, and the material 9 is separated from the AGV trolley 1. The second material sensor 16 may use an infrared sensor.

According to some embodiments of the utility model, the functional components comprise a crash bar 17, the crash bar 17 being arranged on the front side of the frame 11.
