Embodiment Construction

[0039] special reference Figures 3 to 12 , these figures show a first embodiment of a machine for manufacturing buttons according to the invention, which machine is generally designated by the reference numeral 10 .

[0040] The machine 10 firstly comprises a base 12 on which all the processing units of the machine 10 itself are supported. It is of particular importance that known hopper-type container means 14 are supported on the base 12 for the plurality of disc-shaped elements 100 which must be ground before their final transformation into buttons.

[0041]A feeding device 16 is operatively connected to the container device 14, which feed device 16 selectively feeds the disc-like elements 100 one at a time to the clamp holding device 18 by dropping through a spring channel (not shown). A jig holding device 18 fixed to the base 12 is capable of holding and rotating the single disc-shaped element 100, while a processing device 20, also fixed to the base 12 and arranged adj...

Abstract

A machine (10) is described for manufacturing buttons comprising a base (12); a container device (14), supported on the base (12), capable of containing a plurality of disc-shaped elements (100) to be machined on the machine (10); un supplying device (16), operatively connected to the container device (14), capable of selectively supplying, by fall through a channel, a single disc-shaped element (100) at a time to a clamp gripping device (18); a clamp gripping device (18), fixed to the base (12), provided with two opposite and coaxial gripping shafts (22, 24), which block the disc-shaped element (100) by pressure, acting onto its two opposite and parallel surfaces, and set it into rotation; and a machining device (20), fixed to the base (12) and arranged adjacent to the clamp gripping device (18), capable of machining the outer circumferential edge of the disc-shaped element (100) held and made to rotate by such a clamp gripping device (18). The clamp gripping device (18) is provided with a self-centering positioning system (52) of the disc- shaped elements (100), arranged below the supplying device (16) and capable of positioning each disc-shaped element (100), independently from its outer diameter, substantially coaxially with respect to the opposite gripping shafts (22, 24) of the clamp gripping device (18).

Description

technical field [0001] The present invention relates generally to a machine for the manufacture of buttons, and more particularly to a machine capable of grinding semi-finished parts forming buttons. Background technique [0002] As is known, buttons are usually produced on machines provided with tools that can be rotated and / or moved relative to the initial semi-finished product held by specific clamping devices in order to obtain the required button shape and number of holes. The substantially cylindrical initial semi-finished product is called a disk-shaped element. [0003] Buttons can be made from a wide variety of materials, as long as the material is sufficiently hard, like for example wood in general, metal, bone, mother of pearl, horn, ivory or plastic. [0004] The production of buttons, especially of buttons made of precious materials such as horn, mother-of-pearl or ivory, leads to some drawbacks due to the possible large variations in diameter of the initial di...
