TECHNICAL FIELD
The present application relates to a field of modular quick replacement technology for changing specifications in automated production lines, and specifically relates to a three-dimensional quick replacement machine for a production line.
BACKGROUND
In the production line of longitudinal seam steel pipes, due to diversity of products, manufacturers often need to change product specifications of their production lines, and the production lines also are required to have ability to process products of multiple specifications. So, solutions for the production lines to handle quick replacement of the product specifications and efficiency of the replacement are involved. When changing the product specifications in the existing longitudinal seam steel pipe production lines, manual operations on line are generally used to replace an entire set of rollers that need to be replaced while the production lines are shut down, and this manner is inefficient and has low safety. However, although the entire operation for changing specifications can be completed effectively and safely by robot in a manner of fully automatic roller replacement, the equipment for roller replacement by robot takes up a lot of space and is expensive, it is only suitable for frequent replacements of multiple specifications on one production line, while is not very suitable when only two specifications need to be replaced on one production line. Therefore, the person skilled in the field needs to develop a three-dimensional quick replacement machine for a production line that can efficiently, safely, and cheaply solve the problem of quick replacement of two specifications, and this has become a trend.
