Abstract

The invention relates to a method for operating a machine, in particular a coating machine, preferably a narrow-edge coating machine, such as those used e.g. in the furniture or component industry. The method comprises the following steps: transferring a plurality of input values from a storage device to a control device of the machine, the input values relating to at least one material and/or tool used in a processing of a workpiece, preparing the machine for processing based on the input values, processing a workpiece with the prepared machine, changing the input values based on the processing and/or the product, and transferring the changed input values to the storage device.

First claim

The invention claimed is:

1 . A method for operating a narrow-edge coating machine, comprising the following steps:
transferring a plurality of input values from a storage device to a control device of the machine, the input values relating to at least one material and/or tool used in a processing of a workpiece, preparing the machine for processing based on the input values, processing a workpiece with the prepared machine by applying a coating to a narrow edge of the workpiece to form a product with an adhesive joint, changing the input values based on the processing and/or the product and transferring the changed input values to the storage device, wherein a control command to order a material and/or a tool is generated based on an actual material consumption value; wherein after the coating is applied to the narrow edge of the workpiece, a quality check is carried out based on the visibility of the adhesive joint of the product by sensors of the machine; and wherein the input values are changed based on the quality check.

2 . Method according to claim 1 , wherein the storage device is a cloud, the machine having an internet-enabled interface.

3 . Method according to claim 1 , wherein, after the step of transferring the plurality of input values, a comparison is made with at least one machine parameter.

4 . Method according to claim 1 , wherein a material testing step is carried out after the preparation step and before the processing step.

5 . Method according to claim 4 , wherein the material consumption value is calculated during the material testing step.

6 . Method according to claim 1 , wherein preparation comprises one or more steps selected from: adjusting a processing temperature of an adhesive, selecting a coating material, adjusting the machine based on the workpiece to be processed, adjusting and/or positioning one or more processing devices.

7 . Method according to claim 1 , wherein the processing of a workpiece comprises one or more steps selected from: heating a coating material and/or workpiece, applying an adhesive to the workpiece and/or coating material, detecting a fed coating material, pressing a coating material onto a workpiece.

8 . Method according to claim 1 , wherein a quality check is carried out on the product by sensors of the machine, before the input values are changed.

9 . Method according to claim 1 , wherein, after the workpiece has been processed, the actual material consumption value is transferred to the storage device.

10 . System for operating a narrow-edge coating machine, comprising:
a storage device and a control device, a device for transferring a plurality of input values from a storage device to a control device of the machine, the input values relating to at least one material and/or tool used in a processing of a workpiece, wherein the control device is adapted to:
prepare the machine for processing based on the input values, wherein the processing involves applying a coating to a narrow edge of the workpiece to form a product with an adhesive joint,
output control commands for processing a workpiece with the prepared machine,
change input values based on the processing and/or the product and transfer them to the storage device,
transmit a control command to order a material and/or a tool based on an actual material consumption value, and
after the coating is applied to the narrow edge of the workpiece, perform a quality check based on the visibility of the adhesive joint of the product using sensors of the machine and change the input values based on the quality check.

11 . System according to claim 10 , wherein the storage device is a cloud, the machine having an internet-enabled interface.

12 . System according to claim 10 , further comprising a testing device for checking the material.

13 . Method according to claim 5 , wherein the material consumption value refers to the consumption of a coating material or of an adhesive.

14 . Method according to claim 9 , wherein the actual material consumption value refers to the consumption of an adhesive and/or a coating material.

15 . Method according to claim 1 , wherein during the quality check, an adhesive joint of the product is tested.

16 . Method according to claim 1 , wherein in the quality check, an adhesive joint of the product is tested.

17 . System according to claim 10 , wherein during the quality check, an adhesive joint of the product is tested.

18 . System according to claim 10 , wherein in the quality check, an adhesive joint of the product is tested.

19 . Method according to claim 1 , wherein the processing comprises applying a coating material in sheet form to the narrow edge of the workpiece.

20 . System according to claim 10 , wherein the control device is adapted to prepare the machine for processing based on the input values, wherein the processing involves applying a coating material in sheet form to a narrow edge of the workpiece.
