Abstract
Description
- The object of the present invention is a line and method for producing and packaging metal profiles for plasterboard walls or ceilings.
- In particular, the line according to the invention is intended for the production and packaging of metal profiles for plasterboard walls or ceilings.
- As it is known, plasterboard walls and ceilings comprise a frame whereto plasterboard panels are fastened. In turn, the frame comprises U or C shaped metal profiles that are connected to each other.
- Such metal profiles are produced according to standard lengths. Installers at a construction site cut the metal profiles to the sizes imposed by the specific installation requirements.
- Such a method for the installation of plasterboard walls or ceilings is, however, costly in terms of both working time and wasted material. The operations for cutting the metal profiles are in fact time-consuming and result in a high production of waste (unusable metal profile sections).
- Within the sector of plasterboard walls and ceilings installation there is therefore the requirement to render installation operations less burdensome, thereby reducing timescales and waste.
- To date, however, this requirement has not been met insofar as any customized production of metal profiles would be excessively costly, especially due to the complexity that would be introduced into the packing operations of the metal profiles.
- As is known, metal profiles are produced in batches of profiles with the same length to then be packaged in the form of packages consisting of pairs of profiles that are coupled with each other in order to reduce their volume. Each package takes the form of two or more layers formed from a plurality of pairs of profiles arranged one above the other.
- A traditional plant for the production and packaging of metal profiles for plasterboard walls or ceilings is structured as a profile production section and a profile packing section.
- In more detail, the profile production section, comprises, sequentially:
- a profiling machine, provided with a punching assembly and fed upstream by at least one metal strip reel supported by a winder;
- a profile cutting unit;
- a profile extraction bench which is suitable for centering each individual profile in length on a predefined first centering axis.
- The profile packaging section, comprises, sequentially:
- a profile coupling bench which is suitable for receiving the profiles centered in length on the first centering axis from the profile extraction bench to couple them together two by two;
- a bench for forming layers of coupled profiles, which bench receives the coupled profiles from the coupling bench to place them side by side with each other in the lengthwise direction so as to form a layer of coupled profiles;
- a strapping machine which is suitable for applying one or more straps around a layer of coupled profiles so as to make it a manipulable unit;
- at least one single layer translation bench;
- a bench for centering layers of coupled profiles which is suitable for centering a single package in length with respect to a predefined second centering axis;
- a package forming bench which is suitable for taking single layers from the centering bench and laying them one on top of the other so as to form a package of profiles.
- The single profile or single layer centering and levelling operations in the profile extraction bench, the coupled profiles layer forming bench and the layers centering bench are performed by means of mechanical stops and thrust paddles.
- For every change in profile length it is necessary to reposition the mechanical stop in the profile extraction bench, in the coupled profiles forming bench and in the layers centering bench.
- Such operations require that the profiling machine be stopped with more or less downtime depending on the frequency of the change of the profile length.
- Currently, producing packages of profiles cut to length is extremely costly in terms of downtime due to the lack of flexibility of the production and packaging lines in relation to changing the length of the profiles.
- There is therefore the need to have a line for producing and packaging metal profiles for plasterboard walls or ceilings that makes it possible to simplify the operations of changing the length of the profiles, thereby reducing downtimes.
- Therefore, the main object of the present invention is to eliminate, fully or partially, the drawbacks of the aforementioned prior art, by providing a line for producing and packaging metal profiles for plasterboard walls or ceilings that makes it possible to simplify the operations of changing the length of the profiles, thereby reducing downtimes.
- A further object of the present invention is that of providing a line for producing and packaging metal profiles for plasterboard walls or ceilings that it is operationally simple to control.
- A further object of the present invention is that of providing a line for producing and packaging metal profiles for plasterboard walls or ceilings with manufacturing costs that are comparable to traditional apparatuses.
- The technical features of the invention, according to the aforesaid objects, may be clearly seen in the contents of the claims below, and its advantages will become more readily apparent in the detailed description that follows, made with reference to the accompanying drawings, which represent one or more purely exemplifying and non-limiting embodiments thereof, wherein:
