A machine for cutting leathers

Abstract

A machine for cutting leathers (1), comprising: a structure (2) which circumscribes an operating area (3) where the leathers are to be laid, maintained stretched and still such as to allow cutting operations; at least an aspirating plane (4, 40) arranged at the operating area (3) and connected to a depression source (9) such as to maintain the leather stretched and still following activation of the depression source (9); a cutting unit (5), borne by the structure (2), arranged above the operating area (3) and movable with respect thereto, such as to realise the cut In the leathers in the operating area (3); the machine (1) comprising at least two closed-loop belts (6, 66) made of a permeable material and flanked to one another, each comprising an upper branch (60, 606) and a lower branch (61, 616), each of the belts (6, 68) being arranged such that the upper branch (60, 606) thereof remains above and in proximity of the aspirating plane (4, 40), in order to restingly receive the leathers to be cut and in order to enable laying of the leathers thereon; the belts (6, 66) being attracted by the aspirating plane (4, 40) following activation of the depression source (9), such that the leathers thereon remain stretched and still; the structure (2) comprising an outlet passage (7) of the leathers, arranged facing the upper branch (60, 606) of each of the belts (6, 66); each belt (6, 66) being activatable, following the completion of the cutting operations thereon, such that the relative upper branch (60, 606) is movable towards the outlet passage (7) in order for the cut leathers to be transferred out of the operating area (3), externally of the structure (2), independently of the other belt (6, 66).

Description

technical field [0001] The present invention relates to the technical field of processing leather or the like, in particular, the present invention relates to a leather cutting machine. Background technique [0002] In the aforementioned technical fields, it is a well-known requirement to keep the hide fully unfolded during the cutting operation, in order to prevent possible creasing or wrinkling from altering the final desired shape of the hide obtained. [0003] For this purpose, the known hide cutting machines comprise a structure which encloses an operating area in which the hide must be unrolled and kept unrolled and stationary before the hide is subjected to the cutting operation. [0004] Said leather cutting machine comprises, at the relevant operating area, a fixed suction plane made of steel and arranged horizontally, said suction plane providing a plurality of through holes, [0005] The through hole is connected to a low pressure source, ie for example a suction...

Problems solved by technology

In other words, the time to collect the cut pieces constitutes the "bottleneck" of each working cycle, which greatly limits the productivity of the leather cutting machine

[0015] Another drawback is that the collection and sorting operations of the cut pieces, although not requiring special skills, are carried out by the same operators with special skills who are responsible for placing the hides: this therefore means higher labor costs, which This higher labor cost is not in any case indispensable to accomplish the above operations
