Definitions
- the present invention relates to a non-contact deflection device for sheet material, this device being of the type using those of an air cushion established around a substantially cylindrical surface placed at a place where the treated sheet material "in the process" must be diverted.
- Deviation devices of this kind are known, for example, from documents GB-A-2126974 and EP-A-0507218.
- This invention relates to the technical field of manufacturing, processing and processing of sheet, strip or web materials, such as paper, cardboard, fabric, synthetic film, etc. which pass through a machine or industrial installation, where the sheet, strip or sheet undergoes a certain number of changes of direction along its path which causes it to pass in front of successive work stations; the non-contact deflection, thanks to an air cushion, here prevents friction and smearing.
- Machines or installations of this kind often include heating means produced in the form of electric emitters of infrared radiation, which are used in particular for drying, for example drying the ink in the case of printing machines, or elimination of water in paper-making installations, this type of emitter allowing rapid temperature rises and providing great flexibility of use (absence of thermal inertia).
- the infrared radiation drying means usually take place on the straight sections of the path of the sheet material, between two successive deflection cylinders with or without contact (see for example the documents EP-A-0346081, WO-A-8705644 and FR -A-2247687, as well as the aforementioned document EP-A-0507218).
- the machines or The installations in question currently remain very bulky, the deflection cylinders constituting bulky organs which have no active role on the sheet, strip or sheet material treated "on parade".
- the invention aims to avoid this drawback, by providing a technical solution making the deflection devices active without contact, hence a reduction in size of the machines or installations concerned and an increase in their speed, while improving or increasing the efficiency. means of heating / drying by infrared radiation.
- the invention essentially relates to a non-contact deflection device for sheet material, of the type specified in the introduction, in which it is provided in or under the cylindrical surface, in addition to air blowing means creating the air cushion for non-contact deflection, infrared emitters whose radiation is directed radially towards 1 • outside of said cylindrical surface, in the direction of the portion of sheet material being deflected around this cylindrical surface, the flow of blown air ensuring the cooling of the infrared emitters simultaneously with the formation of the air cushion.
- the device which is the subject of the present invention ensures, within the same volume, the contactless deflection of the sheet material, and the heat treatment of this sheet material, that is to say its heating by infrared radiation. .
- the invention therefore provides a considerable saving of space, for the machines and installations concerned which can thus be constructed in a much more compact manner.
- the present invention improves the operation of these emitters and ensures their preservation, since the blown air flow cools the infrared emitters simultaneously with the formation of the air cushion.
- the air flow itself contributes to the drying of the sheet material, so that this drying is accelerated without increasing the total power required.
- the deflection device object of the invention comprises a multiplicity of infrared emitters, arranged in lines and / or in rows following the profile of said cylindrical surface, passages for the blown air being provided between these infrared emitters.
- the emitters of infrared radiation each usually consisting of a tube placed at the focus of a reflector, can become dirty in particular in applications in the field of stationery. It is therefore useful to protect them against soiling.
- Figure 1 is a front view of a device according to the present invention
- Figure 2 is a cross-sectional view, on a larger scale, of the device of Figure 1
- Figure 3 is a view similar to Figure 2, showing a variant of this device.
- the device ensures in a machine or industrial installation the deflection, at an angle A, of a sheet material 1 treated "in the process", which moves according to a arrow F.
- This device also provides heating of the sheet material 1, in its portion being deflected, in particular with a view to drying this material 1 within the framework of a manufacturing, transformation or treatment process.
- the device comprises a box 2, more or less elongated in the horizontal direction, which can be rotatably mounted about a horizontal axis 3.
- the inside of the box 2 is supplied with supply air by suitable means, as indicated diagrammatically by an arrow G.
- the box 2 In its front part, the box 2 forms a cylindrical surface 4, which can in particular extend along a half-cylinder, the generatrices of which are horizontal. Openings 5 are distributed over the extent of the cylindrical surface 4, and deliver air jets to form, between this cylindrical surface 4 and the portion in the course of deflection of the sheet material 1, an air cushion 6.
- the air pressure is regulated by known means, not shown, to allow good tension of the sheet material 1.
- each infrared emitter 7 has a reflector 8, oriented so as to direct the infrared radiation radially outwards, therefore towards the portion of the sheet material 1 being deflected on the cushion of air 6.
- the emitters 7, of known structure can provide, depending on the applications, "short” or “medium” infrared radiation (wavelengths between 0.8 m and 10 m).
- the openings 5, emitting the air jets for the formation of the air cushion 6, are arranged in the gaps which remain between the infrared emitters 7.
- the flow of blown air is heated, for example from an ambient temperature of 20 ° C. to a temperature of the order of 100 ° C., which ensures the cooling of the infrared emitters 7 while improving the drying of the sheet material 1.
- the device also comprises a protective screen 9, made of quartz glass transparent to infrared radiation, of general semi-circular profile corresponding to that of the cylindrical surface 4.
- the rounded protective screen 9 is here composed of quartz glass blades, placed in front of the infrared emitters 7 to protect them from dirt, the blades being separated from each other by intervals which correspond to the openings 5 for the passage of the blown air.
- FIG. 3 shows another embodiment of the device according to the invention, in which the infrared emitters 7 are arranged under the cylindrical surface 4, substantially in a diametral plane. These emitters 7 are always oriented in such a way that their radiation is directed radially towards the outside of the cylindrical surface 4, in the direction of the portion of the sheet material 1 being deflected on the air cushion 6.
- the protective screen 9 comprises solid parts, between which extend openings 5 for blowing air.
- This protective screen 9 is removably and interchangeably mounted on the box 2, so that it can be easily and quickly exchanged.
- the device suitable for diverting sheet, strip or web material of any kind: paper, cardboard, fabric, coated fabric, synthetic film, etc., and by incorporating this device into any type of machine or installation, for all kinds of manufacturing, processing or processing operations.
