DESCRIPTION

TECHNICAL FIELD

The present invention is particularly related to the manufacturers who perform manufacturing by winding on all kinds of paper rolls with or without lycra. The invention is especially related to the circular knitting machines of the textile sector. It relates to the mechanical roller with a bearing which provides production without a roll and without requiring any use of paper roll.

STATE OF THE ART

In the state of the art, the producers of fabric rolls with paper rolls perform their production by winding the fabric on the paper roils. This causes the paper rolls to be junk and not to be used more than once after the fabric roll is used up.

All the fabrics which are knitted in the circular knitting fabric machines with or without lycra are manufactured in any desired meters and weights by being wound on the paper roll of 400 g to 700 g weight attached to the roller of the machine. The function of the paper roll used at the fabric manufacturing stage is to enable the machine roller to be removed from the fabric roll easily.

Normally, the fabric roll to be knitted is knitted by being wound on the roller to which a paper roll is attached. The fabric knitted on the paper roll is thus brought to the manufacturer. After the manufacturer who receives the fabric roll together with the paper roll thereinside uses the fabric, the paper rolls become junk. The fabric roll can be used in various ways such as fabric finishing or dying. However, it is not always possible for the producers, who produce the fabric roll by winding the same on the paper roll and deliver the product to the manufacturer in that way, to re-use most of these paper rolls (although not all of them) which are used by the manufacturer and become junk due to the fact that these paper rolls become deformed in time because of the moisture and other external factors and that the producer of the fabric roll sells his/her product to the manufacturers from all over the world.

A circular fabric knitting machine performs manufacturing by using 15 to 25 rolls daily in average depending on the manufactured fabric type. The use of paper roll in some other sectors is also pretty common. When the production continuity is taken into account, these figures become an element increasing the cost of the manufacturing processes in parallel with these figures reaching to really high levels.

In another state of the art, since this paper roll used for each fabric roll cannot be re-used, a need is arisen for inventions relevant to a system which will avoid the use of paper roll and allow the same to be re-used considering the fact that the price of paper roll is added to the cost of fabric roll and that these paper rolls being used are harmful to environment. A solution with respect to the subject matter is sought with the patent numbered 2009/09843 so as to re-use the paper roll by removing the same from the fabric roll before the fabric is delivered to the manufacturer. It is aimed thereby to solve the problem by using an air-cushioned roller instead of a paper roll and thus allowing the roller to be used more than once. The operating principle focuses on blowing the roller following the fabric knitting process and increasing the diameter thereof. However, some problems are experienced at the application stage of said invention; that is to say, at the stage where the roller used instead of the paper roll is removed from the fabric roll. The fabric rolls press against the roller, on which they are wound, with a great pressure and the roller is stuck inside the fabric roll. It is not possible to take out the roller due to the pressure applied by the fabric against the roller.

Therefore, new developments are needed which will eliminate the disadvantages of increased costs and use of paper which cannot be recycled and bring solution to the problem of the roller which turns out not to be easy to be removed from the fabric roll in the systems which are designed to make the recycling possible.

OBJECTS OF THE INVENTION

The present invention aims to introduce a solution which will eliminate the consumption of paper roll used during the production of fabric in the circular knitting machines and in all other sectors, and thus to reduce the production cost, to avoid cutting the trees, and to protect the environment.

Another object of the present invention is to enable the roller, which is used in the circular fabric knitting machine and on which the fabric roll is wound, to be separated from the fabric roll easily.

Another object of the present invention is to prevent a scenario where the cloth pipe which is found in the air-cushioned roller and placed in the outer layer becomes unusable, cannot confine the air therein, and thus cannot function properly when there is a small tear or hole occurring while being used. Even when impacts and holes are occurred during the use of cloth pipe on the mechanical roller with a bearing more than once, this does not prevent the mechanical roller with a bearing from functioning properly.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 and Figure 2 are the schematic drawings illustrating the mechanical roller with a bearing (14) according to the invention and the operating principle thereof.

In order to form the mechanical roller with a bearing (14) according to the invention, a main shaft (1) and bearing grooves (121) on said main shaft which are created in proportion to the length of the main shaft are obtained. The bearing groove is filled by attaching a bearing having a pin connected thereto and a distance reference member (2), respectively, to said bearing grooves (121) in proportion to the bearing groove. Said pin (4) is connected to the bearing (3) by means of the pin groove (31) before being slid into the groove. When this process is completed, the bearings will have such an arrangement on the bearing groove that they will have equal distances therebetween.

The milled stud (5) is passed through the stud groove (1 1) disposed in the middle of the main shaft (1). A tail shaft (6) is connected to one end of said stud (5) and a head shaft (7) to the other end by means of the threaded ends of the stud (51). In this manner, a structure in which the bearings (3) can rotate freely and in equal intervals on the main shaft which is compressed from both sides by means of the tail shaft (6) and the head shaft (7). It is aimed to make the distance a shorter than the distance b in order for the bearings (3) to rotate easily in the bearing grooves (121) disposed on the main shaft (1). Then, the cloth roll (11) to be used instead of the paper roll is inserted into the elastic ring (8) and the grooved tension strips (9) are clamped into said cloth roll (11) -in such a way that said cloth roll (11) will be therebetween- by means of the mounting member bolt (10) and thus the integrity of the grooved cloth roll (13) to be used instead of the paper roll is provided.

The grooved cloth roll (13) integrated as one piece and to be used instead of the paper roll is slid and attached on the main shaft with a bearing (12) in a way that each bearing groove (1 1) will correspond to grooved strips (9).

The mechanical roller with a bearing (14) which is formed by inserting the main shaft with a bearing (12) into the grooved cloth roll (13) is attached to the circular knitting machine by means of the tail shaft (6) and the head shaft (7). After the fabric knitting machine knits the fabric onto the mechanical roller with a bearing (14), the main shaft with a bearing (12) is pulled and removed from the grooved cloth roll (13). The striped cloth pipe which is emptied shrinks and is taken from the fabric roll after removing the main shaft with a bearing that has a rigid structure. Both ends of said cloth roll (11) are open and the grooved strips (9) move freely. It is aimed to use the mechanical roller with a bearing more than once by repeating said process. In order to repeat the process, namely to re-use the mechanical roller with a bearing (14), the main shaft with a bearing (12) is again slid into the grooved cloth roll and attached to the fabric knitting machine and gets ready for knitting fabric thereon.

Thus, a mechanical roller is formed which not only avoids the paper waste but also can be removed from the fabric roll after the fabric knitting process is finished.

Figure 2 is an isometric drawing of the main shaft which is disposed in the mechanical roller with a bearing (14) according to the invention and connected into the cloth roll (11) by means of the bearings (3). Said main shaft (1) resists the pressure applied by the fabric knitted onto the mechanical roller with a bearing (14) against said mechanical roller with a bearing (14) and provides the rigidity required for the fabric winding to continue properly.

A cross-sectional view of the main shaft (1) is showed in Figure 3. The stud groove (111) and the bearing grooves (121) on the main shaft (1) will be understood more clearly thanks to this drawing.

Figure 4 shows the cross-sectional drawing of the mechanical roller with a bearing according to the invention when the mounting thereof is completed. It is the cross-sectional view where the main shaft with a bearing (12) is inserted into the grooved cloth roll (13).

The schematic drawing for the disposition of the bearing (3) and the distance reference member (2) in the bearing groove is given in Figure 5. The function of the distance reference member (2) will be understood more clearly thanks to this drawing.

Figure 6 is a drawing illustrating the milled stud (5) passing through the stud groove (111) of the main shaft (1); and the tail shaft (6) and the head shaft (7) which prevent the bearings (3) and the distance reference members from getting out of the bearing groove (121) in the main shaft (1) and also allow the mechanical roller with a bearing (14) the mounting of which is completed to be connected to the circular fabric knitting machine.

Figure 7 is a drawing of the distance reference members (2) and the bearing (3) located on the main shaft (1); and again the milled stud (5) passing through the stud groove of said main shaft (1); and the tail shaft (6) and the head shaft (7) connected to both sides of said stud by means of the threaded ends of the stud (51). The mounted form of said parts in this drawing constitutes the structure of the main shaft with a bearing (12). When said main shaft with a bearing (12) is inserted into the grooved cloth roll (13), the mechanical roller with a bearing (14) according to the invention will be obtained.

Figure 8 is a drawing illustrating the ring (8), grooved strip (9), bolt (10), and cloth roll (11). Figure 9 is the mounted drawing of said parts in Figure 8. The grooved cloth roll (13) is obtained by mounting said parts.
