Description

An automatic feeding machine

technical field

The utility model relates to the field of feeding equipment, in particular to an automatic feeding machine.

Background technique

In the process of industrial production, some materials cannot be automatically arranged and loaded, but the trays with materials need to be placed to the place to be processed. At present, most of the feeding trays are manually discharged and loaded, which consumes more labor; some use automatic feeding equipment, but usually need to manually replace the trays one by one, when the materials in a tray are taken out. , manually replace the new tray. Although the labor intensity of labor is reduced, it also brings waste of manpower and affects the efficiency of feeding.

Utility model content

The purpose of the utility model is to provide an automatic feeding machine to solve the problem of low efficiency in feeding trays at present.

In order to achieve the purpose of this utility model, the technical solution adopted is: an automatic feeding machine, including a feeding conveyor line and a return conveyor line arranged up and down, and a transfer line; the transfer line is connected between the output end of the feed conveyor line and the return conveyor There is a lift between the input ends of the line, and the transfer line is connected with a lifting drive device; there is at least one tray stacking position on the feeding conveyor line, and a tray jacking mechanism is provided under each tray stacking position; near the upper The tray stacking position at the output end of the material conveying line is equipped with a tray lifting mechanism that extends between the two trays at the bottom; the input end of the return conveyor line is an empty tray stacking position, and an empty tray is installed below the empty tray stacking position Jacking mechanism; tray mechanisms extending below the bottom tray are provided on both sides of the return conveyor line at the stacking position of empty discs; a stopper is provided at the output end of the stacking position of empty discs.

The tray stacking position and the empty tray stacking position are different stations corresponding to stacking trays.

When working, put each stack of trays on the feeding conveyor line in turn, and transport them from the input end to the output end. During this period, there can be multiple stations, that is, the stacking position of the trays; the trays at the output end are stacked. position, the tray lifting mechanism lifts up the stack of trays (at this time, the tray jacking mechanisms of other tray stacking positions also lift up the trays of their stations to separate them from the feeding and conveying line to avoid interfering with the tray stacking position at the output end as the feeding conveyor line continues to move), the tray lifting mechanism extends between the two trays at the bottom, and the second tray from bottom to top And all the trays above the stack are lifted;

Then the tray lifting mechanism lowers back to the position, and the bottom tray falls back to the feeding conveyor line, and is transported to the transfer line by the feeding conveyor line; after that, the tray jacking mechanism lifts up again, and the tray lifting mechanism returns to its position , so that the rest of the upper trays fall back to the jacking mechanism; the tray lifting mechanism then extends between the two trays at the bottom, so that the reciprocating cycle separates the trays one by one;
