Description

A GREASING EQUIPMENT INTEGRATED TO THE FOLDING UNIT

IN NAPKIN MACHINES

Technical Field

The invention is related to a greasing equipment used in folding rolls being the part folding the napkin in napkin machines.

The subject invention is related to a greasing equipment where the possible abrasion and deformation are prevented by means of greasing the cams and rollers of the folding rolls of the napkin machines by the greasing equipment integrated to the system.

Background of the Invention

Folding rolls are provided in the folding unit of the napkin machines. These rolls are provided with a feature of folding and cutting the napkin by means of operating constantly during the napkin production. Sensitive and methodical operating of the folding rolls is of vital importance for appropriate and healthy napkin production.

These systems operating constantly during the napkin production bring out problems such as heating, abrasion and noise as in each system operating constantly. For example, greasing of the cams and the rollers of these cams has vital importance; at the same time, it will have minimized the said problems.

The folding rolls wrap the napkin around itself by means of rotating constantly and hold the napkin by the help of the holder. The rollers move on the cams so as to perform this action. By means of this, the napkin is folded by constant movement. In normal conditions, these rollers and cams operating in_. dry place get deformed in short times.

In the present implementations there is no equipment present for greasing the cams and the rollers of these cams. Therefore, problems due to abrasion and heating in these parts of the machines are often fallen in with.

Some applications are present in, the registrations of the Turkish Patent Institute related to the Napkin Machines. An application no TR 2008/00945 applied by ICM MAKiNA VE MUHENDiSLiK LTD. STi. on 2008.02.03 is present among these applications. In the abstract part of this application; The invention mentions of a napkin transferring unit enabling the napkin bundle at the amount to form a package to be delivered to the packaging machine feeding conveyor correctly without human touch by means of separating these napkins aligned adjacently according to the desired amount and making horizontal by means of rotating 90° from vertical position after the napkins' being aligned adjacently to the product outlet table in the napkin machines with mechanic folding and in a vertical position.

Another application also belongs to the ICM MAKiNA VE MUHENDiSLiK LTD. STi. Company; wherein its application is made to the Turkish Patent Institute on 2008.01.05 with the no TR 2008/00533 U. In the abstract part of this application; The invention mentions of a printed napkin machine comprising a printing unit where the ink sumps used in the printing (flexo) mechanisms can be adjusted in a way to move forwards- backwards and angular mechanically and a greasing mechanism eliminating the problems such as heating, abrasion and noise.

Description of the Invention

The object of the invention is to integrate a greasing equipment, enabling the cams and rollers related to the folding rolls making the folding of the napkin to be greased, to be integrated to the system.

An object of the invention is to eliminate the friction occurring in the cams and rollers of the folding rolls and the heating resulting from this friction by means of the greasing equipment integrated to the system.

Another object of the invention is to enable the folding rolls to operate sensitively and methodically by means of the greasing equipment integrated to the system.^"

Another object of the invention is to eliminate the problems such as abrasion and noise by means of the greasing equipment integrated to the system.

Another object of the invention is to expand the usage life of the rollers and cams operating in a dry place as a result of operating in a greasy place by means of the said greasing equipment; therefore, to eliminate the processes of repairing and maintenance and to obtain a product more economical for the consumer.

So as to achieve the abovementioned objects; intended to prevent the heating an abrasion of the cams and rollers operating in constant circular movement in the folding unit, it comprises at least one greasing equipment having at least one seal positioned in a way to be opposite to the cams and rollers by means of being fixed on the said conveyor body, at least one grease box providing grease to this seal, and at least one repellent element making constant press to the said seal from the back part.

So as to achieve the abovementioned objects; it comprises at least one wedge where the repellent element is guided and fixed.

So as to achieve the abovementioned objects; it comprises at least one bearing plate where the wedges are fixed and at the same time the seal is fixed and supported from the back part.

So as to achieve the abovementioned objects; it comprises mooring auricles having the parts related to the greasing equipment on it and enabling fixing on the body surface.

So as to achieve the abovementioned objects; it comprises mooring elements enabling the greasing equipment to be fixed completely with the said mooring auricles.

So as to achieve the abovementioned objects; it comprises montage spaces formed on the said mooring auricles.
