Description

Technical Field

[0001] The present invention relates to the technical field of cup stacking machines, and in particular to a working method of a cup conveying device for conveying cups, bowls, boxes, and lids (hereinafter collectively referred to as "cups"). 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 cups, the disposable cups are taken from the cup making machine to the cup stacking machine for stacking by manual or mechanical means. The cup stacking machine is provided with a cup feeding device for transporting disposable cups, and a stacking device for stacking disposable cups together. The cup feeding device is arranged between the cup making machine and the stacking device. The cup feeding device first "loads" at the cup making machine (i.e., loads the disposable cups from the cup making machine), and then transports the disposable cups to the stacking device for "unloading" (i.e., unloading the disposable cups at the stacking device). The cup feeding device plays the role of intermediate transportation between "loading" and "unloading".

[0003] A "plastic cup stacking machine" is disclosed in the Chinese utility model 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 cup delivery efficiency has become a technical challenge faced by stacking machines in the process of upgrading to improve work efficiency. Summary of the invention
