Abstract

The invention relates to a packaging system comprising a work station with a tool component, a loading station with a side panel component, and a thermal system conveying heatable fluid. The thermal system comprises cooling section and/or a heating section. The cooling section conveys the heatable fluid to the tool component and has an actuator configured for regulating the flow volume of the heatable fluid to the tool component. The heating section conveys the heatable fluid to the side panel component and is coupled at least in sections to the side panel component in order to heat the side panel component.

First claim

What is claimed is:

1. A packaging system comprising:
a work station with a tool component, the tool component is comprised of at least one of a forming station for producing one or more package trays and a sealing station for welding a top film onto one or more package trays filled with food products;
a loading station comprising one or more produced packaging trays disposed to be loaded with food products, wherein said loading station comprises a side panel component disposed adjacent to said one or more produced packaging trays; and
a thermal system for conveying heatable fluid, wherein said thermal system comprises a heating section for conveying said heatable fluid to said side panel component of said loading station and being coupled at least in sections to said side panel component in order to heat said side panel component.

2. The packaging system according to claim 1 , wherein said heating section comprises at least one thermal element for conveying said heatable fluid along an inner side of said side panel component.

3. The packaging system according to claim 2 , wherein said at least one thermal element is integrally formed with said side panel component.

4. The packaging system according to claim 2 , wherein said at least one thermal element is removably attached to said side panel component.

5. The packaging system according to claim 2 , wherein said at least one thermal element is configured as an extruded profile.

6. The packaging system according to claim 2 , wherein said at least one thermal element comprises a carrier plate with which said at least one thermal element is arranged on said side panel component.

7. The packaging system according to claim 6 , wherein said at least one thermal element comprises at least one tube for conveying said heatable fluid which is arranged on said carrier plate.

8. The packaging system according to claim 1 , wherein said tool component is at least one of a forming tool lower part, a forming tool upper part, a sealing tool lower part, and a sealing tool upper part of the packaging system.

9. The packaging system according to claim 1 , wherein said thermal system further comprises a cooling section disposed at said tool component, said thermal system operable to convey said heatable fluid to said tool component and having an actuator configured for regulating a flow volume of said heatable fluid to said tool component to cool said tool component, and said cooling section is in fluid communication with said heating section, and wherein said heatable fluid heated by cooling said tool component can be conveyed out from said cooling section into said heating section and used for heating said side panel component.

10. The packaging system according to claim 9 , wherein said actuator is a proportional valve and said thermal system comprises at least one temperature sensor adapted to detect a temperature of said heatable fluid heated by said tool component.

11. The packaging system according to claim 10 further comprising a control unit that is operably connected to said actuator and said at least one temperature sensor and configured to control said actuator based on the temperature detected by said temperature sensor.

12. A method for temperature-conditioning a packaging system that includes a work station with a tool component, wherein the tool component is one of a forming station for producing package trays or a sealing station for welding a top film onto said plurality of package trays filled with food products; and
a loading station with a side panel component, wherein a plurality of produced package trays are disposed at said loading station to be loaded with food products and said side panel component is adjacent to said plurality of produced package trays at said loading station, and
a thermal system for conveying a heatable fluid, said method comprising the step of:
conveying said heatable fluid through a heating section of said thermal system to heat said side panel component at said loading station.

13. The method according to claim 12 wherein said method further comprises the step of:
conveying said heatable fluid through a cooling section of said thermal system to effectuate a cooling of said tool component by absorbing heat from said tool component, and regulating a volume flow of said heatable fluid conveyed to said tool component using an actuator of said thermal system; and
conveying said heatable fluid heated by said tool component from said cooling section to said heating section of said thermal system in order to at least partially transfer energy absorbed in the form of heat during the cooling of said tool component to said side panel component.

14. The method according to claim 13 further comprising the steps of:
detecting a temperature of said heatable fluid heated by said tool component using a temperature sensor;
comparing said detected temperature with a preset temperature value using a control unit; and
controlling said actuator with said control unit.

15. The method according to claim 12 , wherein said heatable fluid is conveyed in a thermal element attached to an inner side of said side panel component.

16. A method for temperature-conditioning a packaging system, the method comprising:
providing a packaging machine having:
a work station with a tool component, the tool component being comprised of one of a forming station for producing package trays or a sealing station for welding a top film onto package trays filled with food products, and
a loading station comprising one or more produced packaging trays disposed to be loaded with food products, wherein said loading station comprises a side panel component disposed adjacent to said one or more produced packaging trays at said loading station;

loading the one or more produced package trays with food products at the loading station; and
conveying a heatable fluid through a heating section of a thermal system to heat said side panel component.

17. The method of claim 16 further comprising the step of: conveying the heatable fluid through a cooling section of said thermal system to cool said tool component, wherein an actuator of said thermal system regulates a volume flow of said heatable fluid conveyed to said tool component.
