Working method of a cup stacking machine

Abstract

The present invention discloses a working method of a cup stacking machine. The cup stacking machine comprises a cup feeding device, a cup stacking device, and a cup transporting device for feeding the stacked cups. The cup stacking device is arranged between the cup transporting device and the cup feeding device. The cup feeding device comprises at least two groups of circulating cup feeding mechanisms. The circulating cup feeding mechanisms comprise a first circulating cup feeding mechanism and a second circulating cup feeding mechanism. The present invention adopts a working mode in which the first circulating cup feeding mechanism and the second circulating cup feeding mechanism operate independently, so that the entire cup feeding device does not affect each other between the loading and unloading and cup feeding processes. The cup feeding device can drive the second circulating cup feeding mechanism to "load" and transport the cups while driving the first circulating cup feeding mechanism to "unload". The entire cup feeding device operates continuously without the need for intermittent start and stop, which effectively improves the cup feeding efficiency, thereby greatly improving the working efficiency of the entire machine.

Description

Technical Field

[0001] The invention relates to the technical field of cup stacking machines, and in particular to a working method of a cup stacking machine. Background Art

[0002] The cup stacking machine is a mechanical device used to stack cups, and is commonly used in the stacking process of disposable cups and disposable bowls. After the cup making machine makes the disposable cup, the disposable cup is taken from the cup making machine to the cup stacking machine by manual or mechanical cup taking.

[0003] A "plastic cup stacking machine" is disclosed in the Chinese invention patent with patent number CN201020196012.3. The plastic cup stacking machine includes a cup delivery mechanism for transporting plastic cups. The cup delivery mechanism drives multiple cup delivery templates (note: equivalent to the "chain plate" in the patent disclosure document) at the chain through "interval rotation" of the active sprocket, so that multiple cup delivery templates circulate between the cup making machine and the stacking device. In order to make the active sprocket perform "interval rotation", the cup delivery mechanism needs to be started and stopped intermittently, that is, "stop", pause the motor, and keep the chain and "chain plate" in a stationary state to perform "loading" and "unloading"; "start", restart the motor, and the chain drives the "chain plate" to transport disposable cups. "Start" and "stop" are constantly alternating. The cup delivery mechanism cannot deliver cups when "stopped", and cannot load and unload when "started", which seriously limits the cup delivery efficiency of the entire cup delivery mechanism, thereby greatly restricting the working efficiency of the entire stacking machine. How to further improve the efficiency of cup stacking has become a technical challenge that must be faced in the upgrading of cup stacking machines. Summary of the invention
