Abstract

A method of supplying paint at a site of application thereof comprises the storing of the pigment component of one or more paints in small containers (6,7) separately from the carrier components of a paint or paints stored in a large container (1). A selected pigment may then be mixed with the correct proportion of carrier just prior to application of the paint in blender pumps,(4;5) connected to the appropriate containers.

Description

  • THIS INVENTION relates to a method of and apparatus for, supplying paint to a site of application thereof, such as a method of, and apparatus for supplying paint for use on road marking vehicles. More particularly the invention relates to a method of supplying paint to a site of application thereof, the paint having a pigment component and at least one other carrier component, in which components of the paint are stored separately in containers.
  • Prior proposed road marking vehicles usually have two separate storage tanks for paint, one for yellow paint and the other for white paint, since these two colours are almost universally the only colours used in road marking applications.
  • The tanks also each have their own pumping system and sometimes each have their own heating system where the tanks are to contain paint that must be kept hot.
  • In most operations only paint of one colour is used, thus leaving paint of the other colour in the appropriate storage tank unused. Where both colour paints are used simultaneously, almost invariably one of the tanks runs empty before the other. This results in a time consuming stop for refiling of the empty tank. Also, the cleaning of any tank to take paint of another colour is very time consuming.
  • While it is desirable to increase the capacity of the tanks to obviate these problems, it has been found to be impractical to accommodate very large tanks on a road marking vehicle.
  • In other applications where paint is used, for example in spray painting, similar problems exist. Paint of a particilar colour shade may be mixed for use in a spraying operation, and if not completely used up is usually wasted.
  • The separation of ingredients of paint of one colour for use in road marking is known. This is done with a view to improving the mechanical methods of, and apparatus for, the application of paint to a surface.
  • In French Patent Specification No. 1,492,468, a system is described in which ingredients of paint are stored separately, the ingredients being such that on mixing the resultant paint commences to harden. The components are mixed to form a paint immediately prior to the application of the paint. The characteristics of the final paint layer are determined by, inter alia, the feeding of the ingredients in a particular predetermined ratio, and the speed of ingredient feed relative to the speed of a vehicle applying the paint to a road marking surface.
  • United States Patent Specification No. 3,083,913, describes an apparatus for spraying paint from a mobile vehicle. The apparatus includes pumps which ensure that at the commencement of operation a first ingredient of a paint is always pumped to a spray apparatus before a second ingredient thereof.
  • These systems do not provide a solution to the problem of wastage of excess paint as a result of its colour not being further required. Neither are they intended to solve the problem of uneven usage of different colours of paint for example on a road marking vehicle.
  • The present invention seeks to reduce or obviate these problems and the present invention is characterised in that at least the pigment component of a paint to be used is stored in a separate container and the paint carrier component is stored in a larger container the pigment being mixed together with the correct proportion of paint carrier component at or immediately adjacent the site of application just prior to paint application.
  • The advantages of the claimed invention lie in that the colouring of the paint is achieved at or immediately adjacent the site of application thereof, and then only during actual application. Thus there is no wastage of the ingredients of the final paint mixture as a result of the above described problems.
  • It is to be understood that reference to "paint" in this Specification includes all colouring matter which may be applied to a surface for the purpose of colouring it, and which comprises a pigment and at least one other component. It includes therefore, for example, inks, colouring matter which requires binding, thermoplastic components, colouring mixtures having two components epoxies, and the like. Thus the paint may include a pigment, a carrier, and a binder or may include solvents or the paint may be a pigment and two component resin paint system. The paint may be heated prior to application.
  • A method in accordance with the invention enables a plurality of paints to be used, i.e. three or more colours, in which case at least the pigment component of each paint colour is stored in a separate respective container at or adjacent the site of application, and the paint carrier comprising a mixture of paint components common to all the paints is stored in a larger container, Thus a desired pigment, and possibly other components, may be mixed with the correct proportion of paint carrier to form paint just prior to application of the paint.
  • The said containers may be located on a mobile vehicle, and preferably on such a vehicle which is used in the road marking industry.
  • The invention also provides apparatus utilising the above method said apparatus comprising a number of containers each having an inlet and an outlet means, the outlet means of each container being operatively connected to a separate respective paint component metering pump and a container large relative to the aforementioned containers, having an inlet and outlet means, the outlet means being operatively connected to each paint component metering pump.
  • Preferably the outlet of at least one pump has a homogenizing unit operatively connected thereto for the blending of a paint being pumped from an outlet in use.
  • A preferred embodiment of the invention is descri- bed below by way of example only with reference to the accompanying drawing which is a diagrammatic representation of an apparatus for utilising a method according to the invention.
  • Referring to the drawing a relatively large container 1, has an inlet 2, and an outlet 3, the outlet being connected in parallel to two component metering pumps 4 and 5.
  • Two further containers 6 and 7, each smaller in size than the container 1 are provided each having an inlet means 8 and an outlet means 9. The outlet of container 7 is connected to pump 4 and the outlet of container 6 to pump 5. Each pump has an outlet 10 which is connected separately to a respective homogenising unit 11. Each unit 11 has an outlet 12 which is connected to paint spraying apparatus (not shown). A heating unit (not shown) may be provided to heat the paint prior to application thereof.
  • All the connections are made with suitable tubing, and the pumps are of a type which are readily available on the market. The apparatus is mounted on a road marking vehicle or the like.
  • The larger container 1 is filled via the inlet means with paint carrier comprising all the components which are common to yellow and white road marking paint. This carrier usually includes such components as resin, fillers and solvent.
  • One of the smaller containers 6 or 7 is filled with yellow paint pigment, usually yellow chrome or a mixture of yellow chrome and Titanium dioxide. Small quantities of one or a combination of two or more paint carrier components may be included with the paint pigment in the correct proportion.
  • The other smaller container is filled with white paint pigment, usually Titanium dioxide. Here too, small quantities of one or a combination of two or more paint carrier components may be included with the paint pigment in the correct proportion.
  • However, other suitable substances which are not normally paint carrier components may be mixed with the pigment to obtain desired results, for example to obtain a desired viscosity of the pigment mixture.
  • In use, the colours may be used singly or simultaneously. Each metering pump, when actuated, will pump the correct proportions of pigment and paint carrier to the homogenising unit and thence to the respective apparatus which applies the paint to a road surface.
  • There will normally be sufficient turbulence in the pumps to obtain blending of pigment with paint carrier but if maximum blending is required, the homogenising units may be included.
  • Since the paint carrier usually comprises about 85% by weight of the final paint, the invention provides an effective means of utilising storage space and supplying paint for example on a road marking vehicle.
  • There is less dange of running out of one colour paint, say yellow, before the other colour paint is used up, and filling the smaller containers with pigment or pigment mixture will be less time consuming than filling a large container with one colour paint. Cleaning of the containers is also simplified.
  • Clearly, many variations of the above embodiment are possible without departing from the scope of the invention. For example, the invention is not restricted to two small containers or two colours, since more small containers could be provided nor to colours of yellow and white, since other colours could be used.
  • Neither is the invention restricted to use in the road marking industry, or to use on a mobile vehicle. The invention is equally applicable for example in the spray painting of metals or metal sheeting such as is used in steel furniture, or in the motor car industry.
