Problems solved by technology

However, this traditional obstacle avoidance method has the following defects: First, when there is an accumulated error in the automatic control process, or when there is a certain displacement between the pallet position and the initial position in other cases, the touch switch can only be used as a passive judgment. The probability of triggering the touch switch when forking the pallet is relatively high, resulting in failure of the action; human intervention is required to adjust the position of the pallet; second, due to the cumula

Embodiment Construction

[0024] The present invention will be described in further detail below.

[0025] In this embodiment, at least one linear positioning device is provided on the forklift, and the bottom of the pallet is positioned by the linear wave emitted by the linear positioning device, thereby determining the relative position of the pallet and the forklift. Wherein the linear positioning device is a laser scanning ranging sensor, usually one is set for reciprocating scanning, and more than two are set for complex terrain, and the center of the transmitting end of the linear positioning device is aligned with the center of the fork structure of the forklift . The linear wave is a ranging laser beam. Specifically include the following steps:

[0026] Step 1, setting the linear positioning device on the forklift, and then proceeding to step 2;

[0027] Step 2, using the linear positioning device to linearly scan and detect the front space in the direction of travel of the forklift,...

Abstract

The invention discloses a positioning method of a pallet fork, and belongs to the field of logistic device control methods. According to the positioning method, at least one linear positioning device is arranged on a forklift, the bottom of a tray is positioned through linear waves emitted by the linear positioning devices, and therefore the position and the posture of the tray relative to the forklift are determined. By means of the positioning method, fork holes can be rapidly positioned, misoperation can be effectively eliminated, and the safety of the tray lifting process and the tray transport process can be improved.

Description

technical field [0001] The invention relates to the field of logistics equipment control methods, in particular to a positioning method for cargo forks. Background technique [0002] The general handling AGV judges whether the fork can enter the pallet smoothly through the mechanical touch switches installed on the two fork heads. When the touch switch on either side collides with the pallet and triggers its action, it is judged that it cannot be entered, and the AGV vehicle stops running. At the same time, the touch switch can be used as a safety switch for the direction of the fork. When an obstacle is encountered during operation, the AGV will automatically stop; the touch switch will automatically return to the neutral position when it is not restrained. However, this traditional obstacle avoidance method has the following defects: First, when there is an accumulated error in the automatic control process, or when there is a certain displacement between the pallet posit...
