Abstract
A rail-guided wagon for transporting a carrier carrying a package in a form and seal machine is provided. The wagon comprises: a set of spaced-apart wheels to be distributed on each side of the rail, wherein a first subset of the wheels to be arranged on a first side of the rail is spring-biased towards a second subset of the wheels to be arranged on an opposite side of the rail.
Claims16
A rail-guided wagon for transporting a carrier in a package form and seal machine, comprising:
- a wagon body;
- a set of spaced-apart wheels to be distributed on each side of the rail, including a first subset of the wheels to be arranged on a first side of the rail and a second subset of the wheels to be arranged on an opposite side of the rail, wherein each wheel is arranged to rotate in a horizontal plane when in use;
- at least one wheel support member pivotally connected to the wagon body and configured to rotationally support each wheel of the first subset of the wheels, while biasing the first subset of the wheels toward the second subset of the wheels;
- and
- at least one spring arranged to urge the at least one wheel support member in an upward direction perpendicular to the horizontal plane.

- a set of spaced-apart wheels to be distributed on each side of the rail, wherein a first subset of the wheels to be arranged on a first side of the rail is spring-biased towards a second subset of the wheels to be arranged on an opposite side of the rail,
- further comprising a spring being arranged to bias the first subset of the wheels towards the second subset of the wheels,
- wherein each wheel of the first subset of wheels is rotationally supported by a wheel support member being pivotally connected to the wagon,
- the wheel support member is pivotally connected to the wagon at a pivot joint being remote from a rotational axis of the associated wheel,
- the pivot joint is formed by a hollow shaft of the wheel support member, said hollow shaft enclosing a rod-like member being fixedly attached to the wagon,
- the rod-like member, as well as the hollow shaft, extends in a direction being parallel with the rotational axis of the associated wheel, and
- the rod-like member is fixed to the wagon at its respective ends, and
- wherein a spring urges the wheel support member upwards, in the vertical direction.
