Automatic tray conveying device

The invention discloses an automatic tray conveying device. The device comprises a conveying unit, a tray stacking and separating unit, a tray conveying unit, a first stacking unit, a second stackingunit and a third stacking unit which are arranged in sequence. In addition, a plurality of optoelectronic switches, a plurality of air cylinders and a plurality of magnetic switches are arranged. Theautomatic tray conveying device is used in cooperation with stacking by a mechanical arm, operators work outside the working range of the mechanical arm, and ways for causing occurrence of accidents are decreased. The device can provide trays for the mechanical arm continuously, the positions where the trays are arranged each time are not changed, the workload of the operators is reduced, operation is more convenient and faster, and the stacking efficiency is improved. 本发明公开了种自动输送托盘装置，包括依次布置的传送单元、托盘码垛分离单元、托盘传送单元、码垛单元、码垛单元二、码垛单元三，并设有多个光电开关、气缸和磁感应开关等。配合机械臂码垛进行使用，操作人员的工作在机械臂工作范围外进行，减少了事故发生的途径。该装置可以持续为机械臂提供托盘，且每次托盘的摆放位置不会发
