Description

ARRANGEMENT FOR ANGULAR POSITIONING OF MILLING ROLLS
FIELD OF THE ART
The Present invention relates to roller mill machines used in milling the cereals.
The invention relates to angular positioning of cylindrical ground milling rolls in roller mill machine used in milling mainly grains and similar products and accordingly bearing arrangements.
The said angular positioning is made once initially and can be used in the same value constantly and it is also likely to change the angle depending on changing conditions.
BACKGROUND OF THE ART
The grains are milled between two rollers on which fluted, and are sorted in various sizes in sieving machines. The sorted goods are re-milled in other milling rolls having threads as per size of the grains.
In addition to the said fluted rolls there are rolls having ground surface performing crushing function. Crystal grained goods (semolina etc.) are crushed and fined with the rollers.
During crushing and fining operation there should an equal distance between rolls so as to allow flow of crushed goods. In case of failure of presence of equal distance between rolls and in case of existence of more distance in some parts, there will be leakage of non-ground, non-crushed goods from open spaces. Such case will lead to problems in flow of goods between milling and sieving components.
During operation on ground rollers decreasing diameter increase from caps of rolls towards medium occurs due to thermal expansion caused by bearing embodiment in bearing of roll caps. Such diameter increase causes concave conveying. (See Figure 5) During crushing, the caps of rollers apply pressure to each other and do not apply pressure on middle parts and thus leakage of non-crushed materials occur in the middle part. In order to eliminate this problem the rolls should be ground in conveyed manner in the predetermined sizes in advance before installation onto machine, which is suggested as a technical solution for goods leakage.
Milling with roll was developed during last quarter of the 18th century and has been used since the beginning of 19th century. The roll lengths of roller mill machines produced until 1970s was generally 60-70 cm. Concave convey amount occurring in short rolls is also little. Its negative impact on crushing is also little.
Due to no need for fine goods regarding flour quality in the past, development of different solution techniques has been prevented.
In new modern mills roll lengths can vary from 100, 125, 150 cm. Therefore, amount of concave convey, occurring in long rolls are too much and the rolls should be conveyed in a very accurate amount. (See Figure 1 ).
Improving flour quality today requires finer milling of goods such as semolina etc. Therefore, it is highly essential that ground rolls are very accurately close to each other and produce goods in equal fine milling from all surfaces.
As conveyed ground benches are expensive and special benches, they are not found in every plant. Therefore, it is necessary to apply grinding operations with roll cylindrical grinding benches only in the locations where roll cylindrical grinding benches are available.
Applied stepped grinding method is the most used method to eliminate the impact of diameter increase in roll caps in roll grinding bench. (See Figure 2) When stepped grounded rolls are used, although partial smoothness is obtained as a result of expansion, goods leakage occurs in cap parts of the rolls.
In cylindrical grinding benches applications decreasing diameter increase in roll caps with conically grinding of cap parts of the roll are also commonly used. (See Figure 3). During use of conveyed or cylindrical ground rolls various problems are encountered. The problems of failure to have exact contact at roll surfaces from time to time due do thermal differences likely to occur in bearing embodiment in rolls having determined convey amount are experienced. In this case the goods going through rolls are milled in different thicknesses along roll surface. In order to eliminate this problem, the roll should be dismantled from the machine and conveyed or conically ground in a determined amount.
PURPOSE OF THE INVENTION
In order to eliminate the problems mentioned in the background of the art above, it is understood that it is highly practical and essential to grind the rolls with roll grinding benches available everywhere and to use them for the reasons mentioned above. In order to eliminate the problems occurring due to thermal conditions, an angle should be formed between central axis of rolls.
Rolls are driven by each other through gears in the roller mill machines produced until recent times. During direct driving by gears it is not likely to use gears in different angles to each other because when gears do not overlap smoothly, problems such as noise, vibration, striking etc. occur. Therefore, it is required to develop more complicated gear driving systems. In this case the system will become more expensive and simple using feature will decrease.
Today rolls can be driven by specially developed strong belts. This allows angular operation of central axis of rolls.
The embodiment being subject of this invention is the positioning of rolls in exact contact with each other against diameter increase occurring after thermal expansion generated by bearing arrangements of longitudinally cylindrical ground two milling rolls. In order to provide such embodiment milling rolls are positioned against each other in angle allowing full contact with each other along their surfaces. Thus, the machine operators will be enabled to use in the machine the rolls cylindrical ground in same amount longitudinally in simple grinding benches, which can be found everywhere. The smooth ground rolls seen in Figure 4 expand from cap parts with the heat produced by bearing arrangements no. 10 and 13, and the rolls expanding from cap part gain the convex position shown in figure 5.
With the help of angular positioning embodiment being subject of this invention the parallel position of two rolls in terms of each other is prevented and rolls can be adjusted in a manner providing full contact along roll surfaces (Figure 6). This contact can be monitored visually, with light control and also fine milling capability of machine can be monitored during operation and ideal angled positioning can be fixed.
Angular positioning embodiments should allow easy re-adjustment depending on decrease or increase in concave convey caused by thermal expansion differences in roll caps.
Angular adjustment can be automatically controlled by means of a control unit controlling angular adjustment of rolls through perception of parameters (heat, time) in order to determine the angel automatically.
There is problem of leakage of non-crushed goods in cap parts of the rolls during the time period from initial operation until reaching operating temperature.
The present invention allows giving small angle to less heating rolls and wider angle to those heating more by help of automatically operating arrangement. The invention is also very important in terms of prevention of efficiency loss arising from on-off operations in the plants not in operation constantly (once or twice a day on shift).
In the cases where fluting of the roll (preferably fine flutes) to mill goods finely, angular location of rolls and elimination of convey has been a very effective method. Because, conveyed fluting technique is not known and used.
The invention has also provided location of fluted rolls in equal distances along contact surface in simple smooth benches, which has not been possible until present time. This case also indicates the invention will lead to an innovation as well as an arrangement in milling and sieving technology diagrams. The invention is also very important in that it has formed an innovation in milling techniques.

DETAILED DESCRIPTION OF THE INVENTION
The present invention solves the problems mentioned in the background of the art by means of changing the positions of the rollers (1 ,2) in terms of each other. For this purpose it is sufficient to give an angular position to one of the rollers (1 , 2) in respect to the other roller. In such case an angle (α) is formed between the central axises (3, 4) of the roller, (see figure 6) The angle formation between the rollers can be made from one bearing point (5, 6, 7, 8) (see figure 6a) as well as mutually from both bearing points (7, 8). In this case, two angles (α) will be formed between central axises. (See figure 6b). The rollers can be positioned side by side in some cases and over each other in other cases in order to form the angle. The case where the angle (α) is formed by means of positioning them onto each other is depicted in figure 6c.
Two milling rolls (1 , 2) can be used in roller mill machines and there are also machines having more than two rolls. In description of the invention only two rolls (1 ,2) have been depicted to give a sample.
It is possible to suggest several embodiments to realize the angular positioning. Figure 7 indicates the drawing showing the situation of the embodiment conducting angular positioning with slope sliding component (9) before performance of angular positioning. The roll (2) has been mounted by means of a moving bearing (10) from moving bearing points (7,8) in a manner allowing moving around a central point (12) over mounting block (11). (See figure 7) The roll (1 ) is fixed onto mounting block (11 ) in a manner bearings (13) and slope sliding component (9) are in between from bearing points (5, 6).
The part of the mounting block (11) on the bearing (5, 6) level have an angular surface (14). Sloppy part of sloppy sliding component (9) is mounted onto angular surface of mounting block (11) in a sliding manner. Slope sliding part (9) are loosened by means of fixing components (15) on the mounting block (11 ) and can be slided forward or backward through moving component (16). The bearing (13) and one end of roll (1 ) mounted to this bearing (13) moves up or down in a manner to cease the current parallel level with the other roll (2) (see figure 6a which depicts the case when one end of the roll (1) is elevated.) In same way the end of the roll (1 ) can also move downward or while one bearing point (5) is elevated, other bearing point (6) can be lowered. (See figure 6b) The position of the sloppy sliding part (9) can be fixed at an appropriate level by means of fixing components (15). The engagement and disengagement distance of the rolls (1, 2) is adjusted by distance adjustment embodiment (17). Distance adjustment embodiment (17) are connected to moving bearing (10) and fixed bearing (13) and the rolls are engaged or disengaged by defeat of tightening force (18) positioned between them.
Figure 8 shows the position of rollers (1 , 2) after performance of angular positioning. As it can be seen, central axises (3, 4) are not on the same alignment. A distance (19) has formed between them.
The purpose of the invention can also be realized by means of an elevation part (20) to be located under the fixed bearing (13) without use of a sloppy sliding component (9). (See Figure 9)
Angular positioning of rolls to each other is provided by means of angular positioning of the mounting block (11) supporting the different angular positioning rolls (1 ,2) . (See figure 10) This can be realized by slight slopening the part affecting both rolls at the same time. This part for the sample given in this example is the mounting block. (11) Another angular positioning has been depicted in figure 11 and figure 12. Figure 11 shows the eccentric angular positioning embodiment (21) before angular positioning of the rolls (1 , 2). Figure 12 shows the eccentric angular positioning embodiment (21 ) after angular positioning of the rolls (1 , 2).
Bearing (13) and mounting block (11 ) are in composite structure here. The roll (2) is mounted in a manner allowing movement of moving bearing (10) moves on eccentric part (22). Eccentric adjustment arm (23) drives eccentric part (22) around moving center (24) on the mounting block (11 ). Upon movement of eccentric part (22) moving bearing (10) connected to eccentric part (22) and one end of the roll (2) connected to the bearing (10) moves up and down in a manner causing loss of parallel position with other roll (1). Driving component (25) provides up and down position of eccentric adjustment arm (23) and fixes the position deemed appropriate. Distance adjustment embodiment (17) adjusts engagement and disengagement distance of both rolls (1 , 2) to each other. This embodiment can be realized in several ways.
Figure 12 shows the moving roller (2) positioned upward in respect to eccentric part (22).
Angular positioning can be made at one end of the rolls (1 , 2) as well as both ends thereof. Equal angles (α) will be formed as a result of moving central axis (3, 4) of the rolls (1 , 2) at both ends of the roll in different directions. (See Figure 6b) Even in very specific cases it is also possible to apply it from all bearing points (5, 6, 7, 8) of both rolls (1 ,2).
The charts indicating quantities or distances can be used on angular embodiments by means of performing statistics and calculations in a manner guiding the angular positioning.
The heat generated by bearing embodiments (10, 13) may not be in the same amount all the times. Therefore, expansion (diameter increase) in ends of the roll (1 , 2) is not always the same. Accordingly, the amount of convex to be caused by ends of rolls expanding in different amounts on the roll (1 , 2) will be different. In such cases the position of the rolls (1, 2) to each other can vary depending on changing parameters.
The heat in the bearings (10, 13) is measured with sensors (26) located on bearing points (5, 6, 7, 8). The motor (28) is driven by a control unit (27) pursuant to such values. The position where it is wished to position the eccentric adjustment arm (23) at which temperature can be adjusted from control unit (27).
The rolls (1 , 2) can also be automatically positioned and operated at various angles to each other according to time or a similar value without relying on the heat values on bearing points (5, 6, 7, 8).
The embodiments such as automatic angular positioning etc. can be adapted to slope sliding part (9) application (Figures 7-8) and application of elevation part (20) to mounting block (11 ) (Figure 10).
The invention also allows application of different angle (α) to rollers (1 , 2) pursuant to changing parameters (time, heat etc.).
Since angular positioning of the end of the roller will create a situation indicated in figure 6a, one end of the rollers (1 , 2) will disengage from the other end. Therefore, it is needed to re-adjust the distances of rolls (1 , 2) to each other.
Since simultaneous moving both ends of one of the both rollers (1 , 2) in different directions in a way deforming the parallel position thereof will provide angular positioning of the rollers (1 , 2) from the center, the situation indicated in figure 6b will occur. Accordingly, it is not required to re-adjust the rollers (1 ,2) in respect to each other during convey elimination operation.
The protection scope of present invention has been specified in the claims section and cannot be limited to the representative applications given in above. It is obvious that a skilled person in the art can realize the invention suggested hereunder by use of similar embodiments or apply this embodiment to other similar purposed fields used in the art. Therefore, it is clear that such embodiments will be deprived of any invention.
