Definitions
- the invention relates to a device for supporting or guiding containers during transport of the containers in a container treatment plant.
- the invention also relates to a container conveyor for transporting containers in a container treatment plant.
- the invention also relates to a method for producing a base body for supporting or guiding containers during transport of the containers in a container treatment plant.
- the invention also relates to a computer program product and a method for transporting containers in a container treatment plant.
- Containers can be transported through the individual system parts in container treatment systems and, for example, filled and sealed. During transport, the containers can, for example, be guided along guide rails or supported on belts or mat chains from container conveyors.
- the guide rails, transport mats, etc. can wear out due to friction with the containers. Streaks can also occur on the containers due to friction. Ultimately, the friction during container transport can lead to disrupted line efficiency.
- the invention is based on the object of enabling improved container transport in a container treatment plant, which is preferably characterized by reduced wear on the containers, guides, etc.
- the device has at least one base body for supporting (e.g. from below) and/or guiding (e.g. laterally) the container during transport.
- the body may have a surface for contacting the containers that is textured to reduce a contact area between the surface and the containers when transporting the containers.
- the base body can consist of a base material and at least one additive material that has a surface energy with a polar component that deviates, preferably significantly, from a polar component of a surface energy of the base material and/or the container (e.g. plastic container) (e.g. larger or smaller), and preferably at least one solid lubricant material.
- the device allows containers and components that come into contact with the containers during container transport to wear out or wear out less quickly.
- the device can preferably enable a reduction in the friction between the containers and the base body for supporting or guiding the containers during container transport.
- a true contact area between the container and the body can be reduced to reduce friction.
- a coefficient of friction of the base body can be reduced by the textured surface.
- wear particles can be removed or migrate via grooves in the texture and can therefore no longer rub abrasively over the surface of the container and the surface of the base body.
- the polar and thus also the disperse portion of the surface energy of the base body By changing the polar and thus also the disperse portion of the surface energy of the base body by admixing the at least one additive material, reduced friction between the containers, which are preferably made of plastic, and the base body can also be made possible.
- the coefficient of friction can depend on the adhesive forces and thus on the distribution of polar and disperse bonds in the tribological system.
