Abstract

A conveyor belt, eg for transporting newly-moulded glassware containers, comprises an elongated mat of fibres, eg of glass. Individual fibres or groups of fibres forming a yarn in the mat are coated with a layer of metal to improve abrasion and temperature resistance. The metal is preferably nickel coated by electroless plating using chemical vapour deposition. A further layer of metal may be electroplated over this layer.

Description

Conveyor Belts This invention is concerned with conveyor belts and, in particular but not exclusively, with conveyor belts which are suitable in use for transporting hot glassware in the form of newly manufactured containers.
The most common machine used for manufacturing containers out of glass is the individual section or "IS" machine. An IS machine has a row of sections each of which operates to manufacture gobs of molten glass into containers. The sections are successively supplied with gobs from a common source and each deposits containers on to a dead plate of the section which is located adjacent to a common conveyor belt of the machine. The conveyor belt runs past the sections and acts to carry away containers from all the sections. Each section has a wipe-out mechanism operable to sweep containers across the dead plate and on to the conveyor belt along an arcuate path at a speed which matches that of the conveyor belt as the containers arrive on the conveyor belt.
Some conveyor belts are formed from an elongated mat of fibres. The mat is normally woven but other constructions are possible. The fibres are of glass but, in principle other fibres which are heat-resistant to at least 5000c could be used. The fibres have to be sufficiently flexible to enable the belt to operate. A very large number of fibres is required to make such a belt, eg there may be thousands of fibres in a belt and individual fibres may have a diameter of approximately 9 microns. The fibres of such a belt are subject to damage as the containers are positioned thereon due to the heat transferred from the glass to the fibres and also due to scuffing. This potential for damage to the fibres means that such conveyor belts have only a limited life.
It is object of the present invention to provide a conveyor belt of the type referred to which has a longer life.
The invention provides a conveyor belt comprising an elongated mat of fibres, wherein individual fibres or groups of fibres forming a yarn in at least a surface layer of the mat are coated with a layer of metal.
In a conveyor belt in accordance with the invention, when the belt is used to transport hot items such as glass containers, the layer of metal can be arranged to be on the fibres which come into contact with the hot items and acts to protect the fibres from abrasion damage and also from excessive heat, since the metal layer conducts heat away from the areas engaged by the hot items.
Preferably, the layer of metal is between 0.5 and 5 microns in thickness, eg the thickness may be approximately 3.5 microns.
The layer of metal may be applied by electroless plating to the fibres before they are woven into the mat.
In this case, size may be applied over the metal layer to assist the weaving operation. Alternatively, fibres in the mat could be coated after formation of the mat. The thickness of the layer of the metal cannot be so great that the fibres cannot be woven but desirably is sufficiently thick and continuous that the hot items do not contact the fibres. The fibres which are coated by the metal layer can be woven into only the surface layer of the mat, eg the top 10 to 20% of the belt.
Alternatively, the layer of metal may be applied to the fibres by chemical vapour deposition. Other possibilities include flame or arc spraying, sputtering, and physical vapour deposition.
Alternatively, the layer of metal may comprise metal applied by electroless plating to the fibres and further metal electro-plated on to the metal applied by the electroless plating. For example, a thin layer of nickel or copper may be electroless plated on to the fibres and a thicker layer of nickel may be electroplated on top.
The layer of metal may comprise nickel which is a metal with a sufficiently high melting point to avoid being melted by hot glassware and provides good scuff resistance.
Furthermore, the reflectivity of the nickel layer may be of assistance in inspection techniques. Alternative metals are copper, silver, cobalt and alloys thereof.
An example of a conveyor belt in accordance with the invention will now be described.
Glass fibres made of E-glass, 9 microns in diameter, were plated by electroless plating with a layer of metal 3.5 microns in thickness. The layer of metal was entirely made of nickel. Nickel was selected because of its abrasion resistance and high melting point. The coated fibres were incorporated in a woven mat with fibres which were not so coated. The coated fibres were used to form substantially all of an upper surface layer of the mat (about 15% of the thickness of the belt was formed from coated fibres). The conveyor belt made from the mat has a significantly longer life that an equivalent belt not containing coated fibres.
