Solution to the problem of GE coding

General Electric has always been troubled by the stability of the printing equipment

There are two different types of inkjet printers working on the packaging line of General Electric (GE) at the same time. One is to use thermal transfer technology to print the barcode on the label and then on the packaging box. The other is the valve type. The printer is used to spray the readable code directly on the package. General Electric must use both types of printers to meet the customer's need for both manual identification information and accurate, high-identification bar code coexistence.

However, the complexity of parts replacement and maintenance will impose higher requirements on the stability of the coding equipment. At the same time, General Electric also uses two types of coding equipment, which makes the requirements for labeling processes on the production line more stringent. For a long period of time, General Electric Company of the United States faced such a problem that the entire production line could not operate normally due to the instability of the marking equipment. “Stability is the biggest challenge facing our company's printers, the logo we use,” said Steven S. Dominic, general engineer of General Electric’s Advanced Sealants and Adhesives Plant on the coast of New Smyrna. Old equipment has many non-stationary parts that are not very stable.This is a major problem that has plagued us for a long time. You have to stop the entire production line because of an auxiliary equipment such as a printer.

In order to solve this problem, General Electric engineers are looking for an identification device that is both stable and stable, and that can simultaneously print manual identification information and accurately identify bar codes. ”

American WorldCom provides thermal foaming printing equipment can help General Electric to solve this problem

Facing the issue of printer stability, Dominica began to consider the idea of ​​inkjet technology for industrial use. Dominica's goal is to use a set of equipment to duplicate existing codes. The device is required to be able to print all information (including bar codes) within the previously used 4 x 4 inch labels. In addition, it is also required to spray directly on the packing box.

The American Society of Communications RSI has designed a thermal foaming coding device that can provide accurate, high-recognition bar codes while also providing human identifiable information. The equipment runs well on the packaging line of the General Electric Advanced Sealant Adhesive Factory. The performance of the thermal foaming printer makes general-purpose appliances replace the two technologies with one technology. And a good solution to the stability problem.

Reliable technology guarantees elimination of wasted time due to replacement of printers and greatly increases productivity

The specific approach is the use of eight HP thermal foaming nozzles on a component by WorldCom. It is installed downstream of the baling line adjacent to the conveyor, but in front of the yard. The device requires a 1/16 inch gap between the printhead and the package when the package passes.

Boxes with leak-proof tubes are loaded with barcodes and human identifiable data at the same time. The print controller can in turn control the print head to print "seamless" barcodes.

A PC-based print controller gives the operator a WYSIWYG interface to observe every code on the screen. With all the coding in its memory, the operator simply starts by entering a different batch number. This takes only a few seconds compared to the long set-up process of previous printers.

The installation of this WorldCom RSI's coding equipment provides a quick replacement time. "Usually we need 5 to 10 minutes to replace the hardware for the old printer, but sometimes we need 30 minutes," Domenico said: "We actually had to stop the entire assembly line to reset the spray for the new run. The code machine, it's too complicated."

General Electric customers did not feel these changes. General Electric employees used hand-held scanners to determine whether the barcodes were readable. “We did not receive any negative feedback on the quality of barcodes from our customers. We are very sure that these barcodes are Read it," said Dominique.

Another simple change factor is the cartridge. Each HP printhead incorporates a 42-milliliter cartridge. This printhead/ink cartridge combination is an insertable and removable structure that allows the operator to quickly change the printhead when the ink supply is slow, while the WorldCom RSI's coding software warns of insufficient ink supply.

Dominic said in his assessment of how WorldCom installed the equipment into the factory. "What the WorldCom RSI does with installation is to provide a good set of equipment and make it work better."

The next step in the development of thermal bubble coding systems at the factory is to evaluate the feasibility of a large-capacity ink supply system to extend the interval between refills of each ink.
