Following lifting type weighing system of AGV vehicle

Abstract

The invention discloses a following lifting type weighing system of an AGV vehicle. The AGV vehicle comprises an AGV vehicle base plate, an AGV lifting device, an AGV rotation device and a carrying platform; the carrying platform is arranged right above the AGV rotation device; the following lifting type weighing system comprises a first two-link mechanism, a sensor installation plate, a weighingsensor, a following lifting component and a second two-link mechanism; the first two-link mechanism is installed on the AGV vehicle base plate and can be rotated on in a vertical plane; the sensor installation plate is installed on the first two-link mechanism and is rotated along with the same to achieve lifting; the following lifting component is installed on the AGV lifting device, and synchronously lifted along with the same; the following lifting component is linked and matched with the first two-link mechanism; the second two-link mechanism is connected between the AGV rotation device and the carrying platform, and is rotational in the vertical plane. The weighing sensor follows the AGV lifting device at non-uniform speeds and automatically completes weighing during a rising process.The system provide by the invention is compact in structure and small in size, and solves the problem that the internal electric wire is staggered and interfered with the electric wire of the weighing sensor when in rotation.

Description

technical field [0001] The invention belongs to the technical field of AGVs, and in particular relates to a follow-up lifting weighing system of an AGV. Background technique [0002] At present, the loading platform on the AGV vehicle has lifting and rotating actions, and there is also a need for weighing during operation. The existing weighing system mostly adopts ascending weighing, for example, electric cylinder power lifting weighing sensor. However, this AGV loading platform is always pressed on the load cell, which is easy to cause damage to the sensor. Moreover, if the load cell is installed on the loading platform, due to the rotation of the AGV vehicle and the loading platform itself, the wires will be twisted together, resulting in electrical contact points, which will affect the safety and reliability of the AGV vehicle. The wires of the heavy sensor are easy to break, resulting in the loss of the weighing function. In addition, the internal space of the AGV ve...

However, this AGV load platform is always pressed on the load cell, which is easy to cause damage to the sensor

Moreover, if the load cell is installed on the loading platform, due to the rotation of the AGV vehicle and the loading platform itself, the wires will be twisted together, resulting in electrical contact points, which will affect the safety and reliability of the AGV vehicle. The wire of the heavy sensor is easy to break, resulting in the loss of weighing function

In addition, the internal space of the AGV vehicle is already very small, and complex mechanisms or large parts cannot be accommodated in it.
