Abstract
Coils (C) containing band-like blank material are stored in a magazine station (M) in a horizontal position, i.e. with the axis vertical. They rest on a level underlay, together with which they can be gripped, still in the horizontal position, and fed to an unwinding station (H), where, together with the underlay, they can be placed horizontally and unwound, in order to feed the band-like blank material to a processing station (B).
Claims62
A method for storing coils of wound band-like blank material and for charging a processing machine with them, which comprises a combination of the following steps:
- (a) the coils are each stored in a magazine on a respective horizontal underlay with the coil axis at right angles to the underlay,
- (b) each coil, still in the horizontal position with the coil axis at right angles to the underlay, is brought on its underlay to an unwinding station, and
- (c) in the unwinding station, the band-like blank material is taken off from the coil while keeping the latter in the horizontal position and is fed to the processing machine after being rotated through 90 degrees.
An installation for storing coils of wound band-like blank material and for charging a processing machine with them, comprising a magazine station in which the coil can be stored in the horizontal position with the coil axis at right angles, and an unwinding station in which a coil support is provided, from which unwinding station the band-like blank material wound on the coil can be fed to a processing station, wherein the coil support is likewise designed for a horizontal position of the coil with the coil axis at right angles, and an essentially level respective underlay is provided for supporting each coil in all stations, on which underlay the coil can be brought from the horizontal position in the magazine station to the horizontal coil support.
An installation as claimed in 16, wherein a horizontal guide is provided for displacement of a vertical guide.
An installation as claimed in 29, wherein the holding part is formed by a cassette for the coil.
An installation for storing coils of wound band-like blank material and for charging a processing machine with them, comprising:
- (a) a magazine station which is operable for receiving and storing a coil horizontally:
- (b) an unwinding station in which a coil support is provided, which unwinding station is located such that the band-like blank material wound on the coil can be fed to a processing station;
- wherein the coil support likewise is operable for receiving the coil in a horizontal position, with the coil axis at right angles to the coil support;
- (c) a respective substantially flat underlay for supporting each coil in all stations, and for transferring the coil from its horizontal in the magazine station to the horizontal coil support;
- wherein the underlay forms the bottom wall of a cassette with a surface which surrounds the coil and is at right angles to the underlay, said cassette having on said surrounding surface at least one gripping zone means for receiving and being gripping by a gripping tool;
- (d) gripping means for gripping and holding, in a horizontal position, the coil stored horizontally in the magazine station, together with its underlay, and placing said coil and underlay on the coil support in this position;
- (e) drive means for an indexed vertical movement and a rotational movement of said gripping means;
- (f) at least on stand in the magazine station with a plurality of horizontally oriented underlay retaining means arranged one on top of the other;
- wherein the stand has a substantially closed vertical wall which is configured to enclose the coils held therein at least as far as the region of their central axis;
- and
- (g) a loading station for receiving newly delivered coils, each coil being received on a horizontally support surface in this loading station, and being placed on said support surface in a horizontal position;
- wherein the loading station is located within range of said gripping means, whereby said gripping means is operable for transferring said coil from said loading station to said magazine station for storing said coil.
