Abstract
A method for feeding automatically metal profiles in bar form entails gripping a group of the metal profiles from a magazine for collecting the profiles and transferring the group of metal profiles or their end to a raised position. The raised metal profiles are arranged on a movable transfer device provided with means for separating the metal profiles, at which the initial portion of a preset number of metal profiles to be fed to the machine at each work cycle is conveyed transversely and counted. The metal profiles are transferred, in the counted number, at receiving elements of the machine, while the excess metal profiles are unloaded inside the collection magazine.
Claims22
A method for automatic feeding of bar form metal profiles in a profile working machine, comprising the steps of:
- (a). gripping a group of metal profiles in bar form from a collection magazine for collecting said profiles;
- (b). transferring said group of metal profiles in bar form to a raised position;
- (c). arranging said metal profiles in bar form on a transfer device provided with separating means for separating said metal profiles;
- (d). transferring along a transverse direction said metal profiles in bar form, and at the same time, counting a preset number of metal profiles to be fed to the working machine at each work cycle;
- (e). unloading metal profiles in excess into said collection magazine from which the profiles originate;
- (f). starting automatically a normal work cycle of the working machine to perform an intended work on selected metal profiles;
- (g). selectively moving with respect to each other the working machine and said collection magazine in order to pick up metal profiles from a different storage unit;
- (h). starting, on request, a new work cycle.
An apparatus for automatic feeding of bar form metal profiles in profile working machines, comprising:
- a collection magazine for collecting said profiles;
- profile receiving elements, provided at the working machine;
- grip means for gripping a group of metal profiles in bar form from said collection magazine and transferring said group of metal profiles in bar form to a raised position;
- a transfer device, for receiving said group of metal profiles in bar form from said grip means and conveying said profiles toward said profile receiving elements of the machine;
- separation means which are associated with said transfer device to produce transfer of said profiles in a transverse direction with the profiles in a uniformly spaced arrangement;
- counting means for counting a preset number of metal profiles to be fed to the working machine at each work cycle.
An apparatus for automatic feeding of bar form metal profiles in profile working machines, comprising:
- a profile collection magazine;
- a shaft;
- a motor, mounted on a frame of said apparatus, to actuate said shaft;
- profile receiving elements, provided at the working machine;
- grip means for gripping a group of metal profiles in bar form from said collection magazine and to transfer said group of metal profiles in bar form to a raised position;
- a screw feeder for receiving said group of metal profiles in bar form from said grip means and mounted so as to rotate on said shaft to transfer transversely said metal profiles, in a uniformly spaced arrangement, toward said receiving elements, counting means for counting a preset number of metal profiles to be fed to the working machine at each work cycle.
