Self-operated method and system for removing group of bottle from container

Abstract

An autonomous case unloading method and system for separating a container from its packing case is disclosed. Said method includes such steps as moving said packing case to a position under clamping unit, dropping the clamping unit down to a predefined position by its dead weight, clamping the container in said case, dropping the case down to separate it from the container, moving the case onto its output unit, dropping the clamping unit along with container down to a container output unit by their dead weight, and releasing the container.

Description

technical field [0001] The invention relates to a self-powered box unloading method and system, in particular to a self-powered box unloading method and system for a box unloading machine. technical background [0002] The unloading machine is mainly used in the production lines of beer, beverage and condiment industries to take out empty containers from the turnover boxes and place them on the container conveying line and the case conveying line respectively. Due to the light weight and high center of gravity of containers such as empty beer bottles and beverage bottles, and in most beer and beverage production enterprises, the vertical deviation between the central axis of the bottle and the bottom of the bottle, and the deviation of the size and shape of the box The range is very large, and the bottle grabber or clamping mechanism of the unpacking machine frequently resists the container mouth or the box mouth, resulting in malfunction and ...

Problems solved by technology

Due to the light weight and high center of gravity of containers such as empty beer bottles and beverage bottles, and in most beer and beverage production enterprises, the vertical deviation between the central axis of the bottle and the bottom of the bottle, and the deviation of the size and shape of the box The range is very large, and the bottle grabber or clamping mechanism of the unloader frequently resists the container mouth or the box mouth, causing malfunction and shutdown

In the prior art, the operation process of the bottle grabber or clamping mechanism of the unloader has the following disadvantages: one, because it is forced to land on the items to be unloaded in the box, if it is pushed against the box or box The container cannot be stopped immediately, but it has to wait until the clamping mechanism is lifted to a certain height and the corresponding sensor is turned on to send a parking command to the driving mechanism such as the motor before stopping. At this time, machinery, boxes or The damage of the clamped items is time-consuming and labor-intensive to solve, and even affects the production speed of the entire production line

Second, the clamping mechanism has to be lifted up and down twice in a working cycle of unloading, which not only wastes the necessary working time, but also causes unnecessary mechanical wear

3. When the bottle is transported horizontally, the power mechanism forcibly drives the clamping mechanism and its clamped items throughout the whole process. The terminal braking wastes energy and causes mechanical wear. At the same time, the clamped containers will swing and collide with each other.

In order to match the production speed of the whole line equipment, equipment manufacturers have to design the unloading machine as a multi-box machine that can unload three, four, five, six or even eight or ten boxes at a time. The structure of the machine has become very complicated, difficult to manufacture, high in cost and price, and increased in power and air consumption during use. At the same time, it has also brought multiple turnover boxes and multiple bottles, multiple grasping or clamping devices and multiple It is even more difficult to align the bottles accurately. During the use, the bottle and the box, the grasper or the bottle clamper and the bottle are frequently pressed against each other, which will damage the machine, the box, and the bottle. Many users cannot afford or dare not use the unloader. box machine

[0004] In the patent or patent application documents of the previous patent application "special technical scheme for the operation of the unloading machine", "box lifting mechanism", "a self-operated operation method and system of a clamping mechanism" and "dropping box device" , all involve a kind of unpacking scheme that clamps the bottle and then falls off the empty box. Compared with the prior art, these unpacking schemes have made significant progress, and have solved the above-mentioned problems and drawbacks from different angles and degrees. After further research and experiments, it was found that when the box is completely separated from the container held by the clamping mechanism by automatically falling off the box, the scheme of horizontally moving the clamping mechanism and the container it holds still has certain limitations. , in some cases, the unloading speed has to be slowed down due to the restriction of bottle pouring factors
