Definitions
- the invention relates to a device for cleaning cylindrical rollers liable to become dirty during their operation. More particularly, the invention relates to the cleaning of conveyor rollers for glass sheets or a glass ribbon, in particular those of the drying rack following an installation for forming flat glass such as a float (forming on a bath of liquid metal generally based on tin).
- a drying rack the glass sheets are conveyed by a bed of rollers.
- the atmosphere of the clothes line is enriched in SO 2 so as to generate a skin of sodium sulphate on the surface of the glass, which reduces the risks of marking of the glass by the rollers.
- there is a progressive fouling of the rollers by the sulfate which leads to an increase in the diameter of the rollers.
- the rollers should be cleaned regularly, preferably without stopping the installation.
- the rollers can be removed from the drying rack individually without stopping operation, but it is a delicate and dangerous operation for equipment and people.
- Another solution has been proposed by US6170293 which describes a mobile system which is placed between the rollers and which cleans them with a wire brush.
- This system involves springs so as to adapt its own geometry to that of the rollers, which can be more or less distorted and more or less parallel. The use of such hot springs (around 600 ° C for a clothes line) is not recommended.
- brushing with a wire brush can scratch the rollers, especially at such temperatures (600 ° C).
- a device is used, not placed between two juxtaposed rollers but a device carried and guided by each roller, independent of the neighboring roller.
- the device according to the invention at least partially surrounds the roller to be cleaned and can be moved parallel to the axis of the roller. It cleans the useful length of the roller by a cleaning means fixed to said device.
- the device at least partially surrounds the roller so that it can be carried by it without falling and so that it can slide along the roller.
- the device can therefore comprise a sort of slide or ferrule surrounding the roller without preventing the rotation of the latter in accordance with its main function.
- the invention relates firstly to a device for cleaning a horizontal roller rotating around its axis, said device being carried and guided by said roller without following it in its rotation, which can be moved by sliding along the roller and cleaning the surface of said roller during its sliding by a cleaning means fixed to said device.
- the rollers to be cleaned are those of a horizontal conveying bed, for example of flat glass
- the device only partially surrounds the roller to be cleaned because it must not prevent the conveying of 'objects on the surface of the roller bed of which it is a part (succession of aligned horizontal rollers, parallel to each other, to form a conveying bed).
- the entire device is located under the conveying plane (contact plane between a conveyed flat object and the rollers).
- the device may in particular comprise two contact surfaces or pads resting on the roller (called “carrier"), fixedly connected to each other by a part passing under the roller, said device being provided with a cleaning system and capable of sliding parallel to the axis of the roller so as to clean its entire useful length.
- the device can comprise two contact surfaces with the upper face of the roller, said surfaces being connected together by a connection passing under said roller, said surfaces serving both to carry the device and to slide on the roller. .
- the device according to the invention cleans the roller while it rotates to fulfill its function (in particular the conveying of flat glass).
- the device according to the invention does not rotate and is not driven by the roller.
- the stop can be a skate.
- the device then has two parallel guides for its movement along the roller: the roller itself and this rail or this rod.
- the device comprises an arm passing under a roller close to that to be cleaned, said arm carrying a stopper which can come into contact with said neighboring roller in order to prevent the device from being driven in rotation by the roller. to clean.
- the cleaning means carried by the device can be a cutting tool.
- This cutting tool can in particular be carried by one of the two pads acting as a contact surface with the roller to be cleaned.
- This cutting tool is placed on the device on the side to be cleaned, that is to say, when it is placed at one of the ends of the roll not yet cleaned, opposite the other end.
- the cutting tool fulfills its function in the device sliding along the roller 'to clean.
- the cutting tool may in particular comprise a succession of juxtaposed teeth in order to cut in the manner of a knife or a serrated saw.
- a metal brush driven in rotation by a motor carried by the device according to the invention As a means of cleaning the roller, it is also possible to use a metal brush driven in rotation by a motor carried by the device according to the invention.
- the device is moved along the roller in order to clean its useful surface. This displacement can be actuated for example by a rod fixed on it by one end, said rod being parallel to the roller to be cleaned, the other end being able to be manipulated for example by an operator to give the device its translational movement along the roller .
- the invention also relates to the use of the device according to the invention for cleaning conveyor rolls of objects, in particular of plates.
- the rollers can also convey a ribbon like a continuous glass ribbon leaving a floating installation.
- FIG. 1 represents (seen from above) a roller 1 driven by a rotation on its axis AA ′, carrying a device 2 according to the invention.
- FIG. 2 represents a set of three rollers 1, 1 ', 1 "juxtaposed and conveying a glass ribbon 3, the roller 1 carrying the device according to the invention.
- This device comprises two contact surfaces (pads 4 and 5) with the upper face of the roller and resting on these surfaces on the roller without being driven by its rotation. These two pads are connected together by the connecting piece 6 passing under the roller.
- the pad 5 is equipped with a cutting tool 7 By sliding along the roller 1, the device 2 moves the cutting tool 7, which rids the unwanted deposits of the roller.
- the device can be moved along the roller by an operator using a rod. fixed to the device and parallel to the roller underneath it.
- the cutting tool is preferably made of a much harder material than the roller, for example tungsten carbide.
- the pads 4 and 5 both have the function of sliding on the roller (and not for one of them to cut the deposits).
- a motor 9 is fixed under the device 2, that is to say approximately at the level of the part 6 forming the link between the two pads.
- This engine rotates a wire brush 10 cleaning the roller 1.
- the rod 8 is used to move the device over the entire useful length of the roller.
- the engine may in particular be of the pneumatic type, that is to say driven in rotation by a flow of pressurized air. This air, after passing through the engine to drive it, can be expelled at the level of the brush and thus serve in addition to cooling fluid.
- the device according to the invention can be mounted on the roller to be cleaned at any time during operation.
- FIG. 4 represents a conveyor roller 1 comprising at one end a portion of smaller diameter 11.
- the device 2 is presented under the spindle 11, the device is mounted around the spindle (movement of the arrow (a)) and place it at the end of the larger diameter part, in zone 12 (movement of the arrow (b)).
- This zone 12 will not be cleaned, but in fact this is not necessary since it is a non-useful zone during operation, that is to say not receiving the glass and not getting dirty so no.
- the rockets pass through the walls of the clothes line to rest on rolling bearings outside the clothes line. Movable parts of the walls generally allow access to the rockets. It is therefore sufficient to remove these movable walls under the rockets to set up the device according to the invention.
- the rod 8 enables the device to be actuated from outside the clothes line.
- the rockets can have a diameter of 200 mm and the central part of the rollers a diameter of 305 mm.
- the device according to the invention can also be used to clean the sizing rollers of glass fibers. These rollers soak in a fairly sticky sizing liquid and become charged with deposits from this liquid over time. If necessary, instead of mounting a cutting tool on one of the pads, it can be fitted with a polishing system rubbing the metal of the roller without scratching it (operation also called "burnishing").
