Abstract
Description
- This invention relates to a method for impregnating, with detergent liquid, fabrics for cleaning high precision rotary cylinders, particularly of printing machines.
- This invention also relates to a shaft for implementing the method.
- In conventional rotary cylinder cleaning devices which use woven or non-woven fabric, it is known to wet a portion thereof with detergent, after unwinding it from a feed shaft and before making it adhere to the surface of the rotary cylinder to be cleaned.
- For this purpose a detergent distribution bar is used usually provided with nozzles facing the fabric and the cylinder to be cleaned.
- With said operating method it is not always possible to achieve uniform detergent distribution, both because of the method of operation of the distribution bar or tube, and because of solid deposits and incrustations which form at the nozzles of the distribution bar.
- In this respect, said incrustations can limit and even obstruct passage of the detergent, with serious operative consequences. In particular, if the fabric is not properly wetted, cleaning the rotary cylinder is pointless as it prevents printing restart or prejudices its quality.
- Another drawback encountered in the known art is that the compressed air usually used to feed detergent to the conventional distribution bar causes undesirable vaporization and dispersion of the liquid detergent into the environment as it leaves the nozzles.
- An object of the present invention is to define a method for impregnating, with detergent liquid, fabrics for cleaning high precision rotary cylinders, particularly of printing machines, which enables the detergent characteristics to be varied on the basis of the working conditions of the cylinders to be cleaned. Another object is to define a method, as aforestated, which enables the cleaning fabric to be wetted in a uniform manner.
- Another object of the present invention is to define a method, as aforestated, which ensures uniformity of this detergent impregnation even after relatively prolonged periods of non-utilization.
- Another object is to define a method, as aforestated, which enables the fabric to be wetted while wound into a reel.
- Another object is to define a method, as aforestated, which enables the detergent consumption to be optimized.
- Another object is to define a device for implementing the aforesaid method.
- These and further objects will be seen to have been attained on reading the following detailed description of a method for impregnating cleaning fabrics with detergent liquid, characterised by radially and centrifugally spraying a reel of fabric (11) through profiled apertures (3) present in a rotatable feed shaft (1), said shaft being internally filled with detergent liquid under pressure in accordance with selectively variable parameters, said liquid being fed into said rotatable feed shaft (1) by suitable pipes provided with rotary seals.
- The invention is illustrated by way of non-limiting example in the accompanying drawing, in which:
- Figure 1 is a schematic horizontal cross-section through a rotary shaft which enables the detergent to be distributed on a reel of fabric by the method of the invention;
- Figure 2 is a vertical cross-section through a cleaning device for rotary cylinders using a rotary shaft of the type shown in Figure 1;
- Figure 3 is a diagram showing the unit for dispensing and feeding the detergent into the rotary shaft of Figure 1;
- Figure 4 shows a variant of the unit for dispensing and feeding the detergent into the rotary shaft of Figure 1;
- Figure 5 shows a device for winding the fabric onto a rotary shaft provided for impregnating it with detergent in accordance with the method of the invention.
-
- With reference to the aforesaid figures, a
rotary feed shaft 1 performs a double function, namely: - conventionally feeding, to typical cylinder cleaning devices, the fabric which is wound in a reel on its outer surface;
- feeding the detergent from its central tubular cavity to an appropriately perforated periphery by centrifugal flow.
- The
rotary feed shaft 1 consists of a tube 2 of length such as to be able to wind a reel of fabric thereon and provided with a series of suitably profiled holes orapertures 3. These profiledapertures 3 are distributed on the surface of thetube 3 in substantially uniform manner. - To the ends of the
rotary feed shaft 1 there are fixed two hubs 4 and 5 extending coaxially to the tube 2. Of these hubs, at least one is holed to connect a usual internal cavity 7 of the tube 2 to external feed means. - The hole provided is a completely axial hole 6 passing through the hub 4.
- The detergent flows through said hole 6 and into the cavity 7 in such quantity and pressure that during operation it is able to emerge radially and centrifugally by passing through the profiled
apertures 3, to uniformly impregnate the reel offabric 11 wound on the outside of the tube 2. - For better distribution of the detergent within the cavity 7 of the tube 2 it is advantageous, but not indispensable, to use a further inner tube 8 of lesser diameter coaxial to the tube 2 and rigid with the hub 4, and provided with
holes 9. The presence of this tube enables better mixing of the detergent liquid and better distribution thereof in the fabric in both the axial and radial directions. In a variant of thefeed shaft 1 there is also aradial hole 10 in the hub 5, disposed perpendicular to the axis of therotary feed shaft 1 and connected via an axial hole (similar to the hole 6) to the cavity 7 of the tube 2. - By means of said
radial hole 10, which is provided with a usual instant connector and check valve, the operator can manually feed the detergent into thefeed shaft 1, using a usual portable feed and dispensing unit for the detergent, or using a temporary floating connection. In this manner the cavity 7 of the tube 2 acts as a detergent reservoir that can supplement or replace the already described automatic device, by using the central axial hole 6. Therotary feed shaft 1, on which the reel offabric 11 has been wound, is rotatably and removably supported between the lateral shoulders of thecleaning device 12, which is installed in the printing machine parallel to and in front of the rotary cylinder to be cleaned, such as that described in Italian patent 1306450, of which a variant is shown in Figure 2 by way of example. - With reference to Figure 3, and to automatic operation, a detergent dispensing and feed unit cooperates with the
feed shaft 1 to transfer thereto the detergent which, if necessary, is diluted with water. - The detergent and water are withdrawn from two
collection tanks tanks - The
tanks pumps solenoid valves rotary feed shaft 1 at suitable pressure (adjustable by usual means). As the various types (or degrees) of soiling could require the use either of the detergent alone, or of water alone, or of a mixture of both at a specific concentration,solenoid valves single pump 29 could be provided which, under the control of thesolenoid valve 30, feeds both detergent and dilution water into the interior of therotary feed shaft 1. If need be, these liquids can be withdrawn from acollection tank 31, where they arrive fromrespective collection tanks valves feed shaft 1 totally and uniformly distribute the predetermined detergent quantity, previously conveyed to its interior, into the reel offabric 11. - The reason for this is to determine its complete impregnation, until saturated, by virtue of its absorption capacity and without the aid of further mechanical means for this purpose. In this respect, knowing the detergent retention capacity of the fabric and the quantity of this latter in use, it is simple to calculate the quantity of detergent to be fed into the
rotary feed shaft 1. The physical-chemical characteristics of the detergent and its uniform initial distribution mean that the reel of fabric is immediately ready for use in nearly all the subsequent cleaning cycles, hence resulting in an increase in the effectiveness of the cleaning action and a reduction in the time of the operative cycle. The method of the invention enables the said uniform impregnation because, even with non-automatic operation, the presence of the profiledapertures 3 enables the liquid contained in the cavity 7 to always wet the lowerly situated region of the fabric reel. This occurs in any angular position acquired following the unwinding of that linear portion of fabric required by the specific cleaning operation. Consequently, if necessary, the method enables the detergent to be fed more than once at variable time intervals into therotary feed shaft 1, determining the quantity on the basis of the diameter assumed by the reel offabric 11 wound on it. In this case, a conventional electromechanical or electronic sensor measures the diameter of the reel and feeds a signal to the electronic control unit, which suitably varies the opening time of thedispensing valves - In particular, the detergent is fed several times in respectively increasing, constant or decreasing quantities, from the beginning to the end of the reel of
fabric 11, depending on whether the variation of the detergent distribution with time prevails or does not prevail over that of the residual quantity of fabric to be wetted. The sensor that measures the reel diameter is used to verify the availability of a new reel offabric 11 and, vice versa, of a reel gradually being consumed or completely depleted. With reference to Figure 2, therotary feed shaft 1 is at rest, or made to rotate intermittently (at suitable speed and time intervals), directly or indirectly, during the detergent feed. It can also be made to rotate to unwind a portion of the reel ofpre-wetted fabric 11, which is brought into contact with arotary cylinder 13 by means of apresser element 14, and rewound on a take-up shaft 15. - In a variant of the detergent feed method, one or more reels of
fabric 11 are wetted before they are located in one ormore cleaning devices 12. - As shown in Figure 5, the
rotary feed shaft 1 is installed in aseparate device 36 by which the fabric is wound intoreels 11 on therotary feed shaft 1 and is impregnated with detergent. Therotary feed shaft 1 is made to rotate continuously, or intermittently (at suitable speed and time intervals), for the following purpose: to wind thereon a portion of a large-diameter reel offabric 38 supported by ashaft 37; or to wind thereon all the fabric of areel 39 of the take-up shaft 15, in order to reuse it. - The aforedescribed dispensing and feed unit feeds the detergent into the interior of the
rotary feed shaft 1, which distributes it into the reel offabric 11 as soon as this latter has been completed following the unwinding of the fabric from thereel 38. - Another possibility offered by the method is to feed the detergent while the
reel 11 is being formed on theshaft 1, i.e. while it is rotating, the centrifugal force then facilitating distribution of the detergent. - When the reel of
fabric 11 is ready for use, therotary feed shaft 1 can be removed from thedevice 36 after cutting the fabric by a usual sliding blade cutter device 40. - Advantageously the method of the invention results in a drastic reduction in the consumption of evaporated detergent, and a large reduction in the emission of volatile organic compounds (V.O.C).
- There is not limit to the type of detergent usable, for example of low, medium or high volatility, or of mineral or vegetable origin, depending on the structural and operational characteristics of the machine on which it is to be used.
- A further advantage is that the quantity of detergent used can be accurately adapted to the quantity and/or quality of the fabric used.
- A further advantage is that the cleaning operations effected are much quicker and effective, as the detergent quantity matches the specific conditions.
