Related Art

The invention relates to an automatic grinding machine providing a non-load surface by means of grinding the surfaces in paper tubes made of cartoon.

The invention particularly relates to a grinding machine realizing operation on the same line as the unit connected to the machine where paper tube is connected without need for a second operator, and automatically grinding the surfaces of paper tube and rollicks in the desired size wherein grinding and polishing operations are conducted simultaneously and providing discharge from the workshop of the dust occurring as a result of grinding operation by use of vacuum. It is the first application in the sector, which performs such action while producing paper pipe.

Background of the Related Art

Rollicks are the parts made of paper in cylindrical form wrapped around with OPP nylon film, stretch film, aluminum folio and circle. Rollicks are in various diameters depending on type of the product wrapped thereon. Particularly, the surfaces of the rollicks on surface of which OPP nylon film, stretch film are wrapped should be smooth and non-porous. Grinding is required to obtain such surfaces. The grind tubes are the bobbins which can be in various sizes in the cylindrical form made of paper by means of wrapping textured yarn, poy yarn and carpet yarn.

OPP nylon films, stretch films and aluminum folios should be wrapped onto fully non-porous surfaces. Even a slight porosity on the surface may cause damage onto nylon and stretch films and folios. For that reason, rollicks and tubes should be subjected to a very well grinding operation so as to obtain a smooth surface not feeling any paper load.

From the present related art, such actions are performed at separate machines after cartoon pipe production, which increases product cost.

Although no similar patent application exists, the patent application numbered 2005/02390 model f mentions a grinding and polishing machine characterized by grinding and polishing in various forms, developed to eliminate the disadvantages arising from loading of the materials to be ground into machine by the operator one by one. However, the said machine is not capable to grind the tube and rollicks.

The patent application numbered 2005/01342 model f. relates to grinding machine providing cleaning of dirt and porous surfaces occurring on the surfaces of wooden materials after the operation.

In conclusion, it is needed to develop a grinding machine capable to automatically grind the paper tube and rollicks surfaces in the desired size without need to a second operator; to conduct grinding and polishing operation simultaneously, to discharge from the workshop of the dust occurring during grinding operation by means of vacuum so as to eliminate the problems and disadvantages listed above, and it has also been necessary to provide a development in the related art due to inadequacy of the existing solutions.
