Abstract
A machine for the surface treatment of long, narrow objects, more particularly vine shoots, with the following features: a frame fixture (3), that defines the direction of motion (32); at least one conveyor module (4), that has at least one pair of conveyor rollers (14), with a conveyance channel between them, and that is arranged with these along the axis of motion (32); at least two brushes (20, 20a) that define a processing channel that runs along the axis of motion (32).
Claims25
A machine for surface processing of long, narrow objects having a cross-sectional dimension and buds thereon, for removing such buds, comprising:
- a frame fixture defining an object feeding axis;
- at least one conveyor module,
- said conveyor module being mounted at said frame fixture and containing at least one pair of conveyor rollers that are rotatably drivable and have a transport gap therebetween, said transport gap having a dimension corresponding to said cross-sectional dimension of said objects to be transported, said transport gap being arranged along said feeding axis, said conveyor rollers having surface structures adapted to advance said objects along said feeding axis without slipping and without damaging said objects;
- and
- tools for removing buds from said objects that are mounted at said frame fixture along said feeding axis,
- said tools containing at least one pair of rotatably drivable brushes co-operating to define a processing gap that is arranged along said feeding axis, said brushes being adapted and arranged to rub off said buds from said objects;
- wherein said objects comprise plant or vine shoots having at least one of a ligneous substance and a bark.
A process for removing buds from vine or plant shoots having a ligneous substance and a bark, comprising the steps of:
- entering said shoots, one after the other, into a transport gap of a pair of conveyor rollers;
- advancing said shoots along a shoot feeding axis by rotating said conveyor rollers and gripping said shoots by surface structures of said conveyor rollers that advance said shoots along said shoot feeding axis without slipping and without damaging said shoots;
- and
- rubbing off said buds from said shoots by rotating brushes that are arranged along said shoot feeding axis and at an adjustable distance thereto, said rubbing off being carried out without damaging said bark or said ligneous substance of said shoots.
