Abstract
In order to provide a filling apparatus which is capable of advantageously delivering a foamable material having a necessary amount into a closed cross section of a vehicle body, in an embodiment of the present invention, there is provided a filling apparatus for filling a closed cross section of a vehicle body with a foamable material is provided, wherein the foamable material is a foamable two-liquid polyurethane material, wherein the filling apparatus comprises a delivering part for delivering the foamable material into the closed cross section of the vehicle body, and wherein the filling apparatus further comprises an input part into which a delivery command value and correction values to set a real delivery amount are input.
Claims19
A filling apparatus for filling a closed cross section of a vehicle body with a foamable material, comprising:
- a control part operable to calculate a real delivery amount of the foamable material from a delivery command value and correction values;
- a delivering part for delivering the foamable material into the closed cross section of the vehicle body, wherein the foamable material is a foamable two-liquid polyurethane material;
- and
- an input part into which the delivery command value and the correction values to set the real delivery amount are input, wherein the correction values comprise a delivery correction value of the foamable material, wherein the delivery correction value is an intercept value of an approximate linear formula, the approximate linear formula being calculated in advance from plural delivery time periods of the foamable material set in advance and a standard delivery amount of the foamable material in each of the plural delivery time periods.
A filling method for filling a closed cross section of a vehicle body with a foamable material, comprising:
- delivering the foamable material into the closed cross section of the vehicle body using a delivering part, wherein a foamable two-liquid polyurethane material is used as the foamable material;
- and
- determining a real delivery amount or a real time period of the foamable material in advance in accordance with an equation using at least a delivery correction value and an expansion ratio correction value, the equation comprising:
- A real delivery amount or a real time period of a foamable material=(a delivery command value of the foamable material+a delivery correction value of the foamable material)×an expansion ratio correction value of the foamable material.
A filling apparatus for filling a closed cross section of a vehicle body with a foamable material, comprising:
- a delivering part for delivering the foamable material into the closed cross section of the vehicle body, wherein the foamable material is a foamable two-liquid polyurethane material;
- an input part into which a delivery command value and correction values to set a real delivery amount are input, wherein the correction values comprise a delivery correction value of the foamable material, wherein the delivery correction value is an intercept value of an approximate linear formula, the approximate linear formula being calculated in advance from plural delivery time periods of the foamable material set in advance and a standard delivery amount of the foamable material in each of the plural delivery time periods;
- and
- a control part to calculate the correction values based on an expansion ratio correction value of the foamable material, wherein the control part is operable to calculate the expansion ratio correction value of the foamable material based on a deviation ratio between a standard expansion ratio of the foamable material and a measured expansion ratio of the foamable material.
