Abstract
An oven (10) for rapidly drying materials printed on small metal objects, such as flat metal sheets (50) for use in making metal cans, comprises a flame-heating section (30) into which such sheets are carried on a conveyor (48), and a 'hot air' heating section (32) into which said sheets are subsequently conveyed. Flames produced by gas- fired burners (73) in the flame heating section impinge directly on said sheets, and hot combustion gases are led off via a communicating duct (40) into the hot air heating section, where they emerge on to said sheets from nozzles (84). The flow of gases through said communicating duct is variable, by means of a fan (44), and their temperature can be increased, by operation of a gas-fired control burner (42). A controllable exhaust duct (34) controls the proportion of combustible solvent in the flame heating oven section. Recirculation of some hot gases from the hot air oven section is achieved via a recirculation aperture (87) in the roof of that oven section. <IMAGE>
Description
SPECIFICATION
Oven for drying matter printed on metal objects
This invention relates to an oven that is suitable for use in drying and/or curing decorative protective and other matter printed, coated or otherwise applied to metal objects such as thin sheet-metal pieces or articles. For convenience only, such metal objects or articles will be referred to hereafter as printed metal objects, the application of such printed materials will be referred to as printing, and the materials applied will be referred to as printed materials.
Modern printed materials used in forming inscriptions and decorative matter on metal sheets and other metal objects are capable of being dried and/or cured in a very short time interval, for example, of the order of 3 seconds, so that it is wasteful of space, time and energy to use drying ovens of the hitherto conventional kind, even if they are modified by reducing their length so as to suit the new range of drying/curing times.
In what follows the term drying is intended to include curing where appropriate.
In such conventional ovens for drying printed materials applied to metal sheets it has been customary to stack such sheets on edge on a conveyor passing through the oven, being spaced apart thereon by supports carried by the conveyor.
Though such supports (known in the art as wickets) have been constructed with minimum material and take up minimum space, those supports never-theless limit the closeness of adjacent stacked plates, and hence the capacity of the oven for given length and moreover they represent a source of heat loss since they take up heat from the oven each time they enter, and give up their heat to the atmosphere each time they leave.
In one particular field, relating to the manufacture of metal cans, each such metal sheet has in the past commonly constituted a plurality of blanks for the manufacture of articles (cans), the blanks being produced by subdividing the printed sheet after printing and drying.
With the quick drying printing materials that are now available, advantageous results can be obtained by subdividing such metal sheets into requisite small sizes suitable for forming said blanks before applying the printing materials, then printing said blanks, and finally by heat treating said printed blanks to dry the material printed on said blanks, said blanks then being ready for forming into the intended articles.
According to one feature of the present invention an oven suitable for drying such small printed blanks has first and second sections arranged contiguously and through which printed blanks or other articles are to be carried on a conveyor, said first section being provided with gas fired main burner means for flame drying said printed materials on said blanks or articles as they pass through that section, and a communicating duct arranged to carry away hot combustion gases from said first section and to deliver them to nozzle means mounted in said second section for the further heating of said blanks or articles by said gases as they issue from said nozzle means onto said blanks or articles as they move through said second section of the oven.
Preferably, said communicating duct incorporates a fan for controlling the rate of flow of said combustion gases through said nozzle means into said second section. Said communicating duct may also incorporate a gas fired control burner by means of which the temperature of said combustion gases maybe increased when required to elevate the temperature of said gases present in said second section. Said control burner may be controlled automatically by means of a thermostatic device in said section, so as to maintain the temperature in that section within a given range of values. Furthermore said fan may be automatically controlled to assist in maintaining said temperature in said second section.
Said second section of the oven may also be provided with a recirculation aperture which communicates with said communicating duct and which is controlled by an adjustable damper for the purpose of allowing as required a proportion of said combustion gases issuing from said nozzle means to be recirculated into said communicating data for reheating and subsequent delivery again through said nozzle means to said second section.
Preferably, said first section incorporates an exhaust gas duct disposed so as to extract exhaust gases from a zone near the entry end of that section, and said exhaust gas duct is controllable by means of an adjustable damper and/or an exhaust fan to vary the rate of extraction of the exhaust gases.
Said main burner means preferably comprises a plurality of burners arranged in sequence along the path of said articles through said first section, and positioned so that their respective flames play on the printed surface of said articles, thereby to progressively and rapidly raise the temperature of such articles. Preferably, where such articles comprise flat metal sheets, each such burner is arranged so that its flame plays on such sheets across the fuli width thereof.
Likewise said nozzle means in said second section preferably comprises a plurality of nozzles arranged in sequence along the path of said articles through said second section, and positioned so that the respective jets of combustion gases play on the printed surfaces of said articles, thereby to progressively raise still further the temperature of each such article, and to ensure uniform heating of each such article.
Preferably said articles are carried on said conveyor with the printed surfaces thereof exposed upwardly, and said burners and nozzles are disposed above the conveyor and heat said articles from above, said flames and jets being directed downwardly.
The conveyor may advantageously comprise at least two parallel transversely-spaced, endless bands of a heat resisting metal, which bands are supported outside said oven on a pulley system which incorporates a resilient biassing means (preferably air operated) for maintaining the bands at a desired tension. Where said articles comprise flat sheet metal blanks, said bands are conveniently spaced apart so as to support said blanks near their respective edges.
Intermediate supports for the conveyor bands may be provided within the respective oven sections so as to control the sag in the upper, article-carrying parts of their respective bands. Both the upper and lower parts of each said band is preferably arranged to pass through said oven.
Other features of the present invention and the advantages thereof will appear from the description that follows hereafter One quick drying oven embodying the present invention will now be described by way of example and with reference to the accompanying diagrammatic drawings in which:
Figure 1 is a longitudinal vertical sectional view taken at the Section l-l shown in the Figures 2 and 3;
Figure 2 is a transverse vertical sectional view taken at the Section ll-ll shown in the Figure 1; and
Figure 3 is a transverse vertical sectional view taken at the Section Ill-Ill shown in the Figure 1.
Referring now to the drawings the oven 10 comprises an insulated oven body 12 defined by upper and lower walls 14, front and rear side walls 18,20, and left and right end walls 22, 24 in which are formed article inlet and outlet apertures 26, 28 respectively.
The oven body encloses two contiguous oven sections, namely, a direct-flame heating or combustion section 30 extending inwardly from the inlet end wall 22, and a "hot-air" heating section 32 extending inwardly from the outlet end wall 24.
An insulated exhaust duct 34 leads off upwardly from the inlet end of said combustion section 30, and incorporates a controllable damper 36 and an exhaust fan 38; whilst an overhead insulated communicating duct 40 connects at its left-hand end with the inward end ofthe combustion section 30, and its right-hand end centrally with said hot air section 32.
The communicating duct 40 incorporates at its inlet end a controllable "control" gas burner 42, and at its outlet end a circulating fan 44 which is connected to an externally-mounted, variable-speed, driving motor 46.
A conveyor 48 for conveying flat printed sheet metal blanks 50 (for subsequent conversion into metal cans for containing for example paint) through the oven body comprises two similar, thin, endless, metal bands 52, 54 (preferably of stainless steel) spaced transversely apart and stretched over respective pairs of crown profiled metal pulleys 56,58 which are disposed externally of the oven at opposite ends thereof. Pairs of metal idler pulleys 60,62, likewise crown profiled, co-operate with the lower runs 64 of the respective band to reduce the vertical separation of the lower and upper runs64, 66 of the two bands, thus enabling the said inlet and outlet apertures 26, 28 to be minimum height, and thereby minimizing the potential loss of hot gases through said apertures.The pair of pulleys 58 at the oven outlet end are driven at constant speed (when in operation) by an adjustable speed driving motor 68, whilst the pair of pulleys 56 at the oven inlet end are urged in a band-tightening direction (leftwards in
Figure 1) by air pressure operated biassing piston and cylinder devices (not shown).
Within the oven body the respective upper runs 66 of the two conveyor bands are supported at intervals by cylindrical supports 70 carried in pairs on cantilever support arms 72. These conveyor band supports limit the sag of the top runs 66 of the conveyor bands, and damp any tendency for said bands to move in transverse directions across the width of the oven body.
Small rectangular, printed, tinned sheet-steel can blanks 50 (typically of sizes between 100 x 250 mm, and 300 x 600 mm) are received at intervals (from a blank printer or decorator not shown) onto the left-hand input end of the conveyor 48, the blanks being positioned centrally with respect to the respective conveyor bands 56, 58. The blanks are carried, spaced axially apart on the conveyor, into the oven body through said inlet aperture 26, through the combustion and hot air sections of the oven body, and then leave through said outer aperture 28, being delivered at the pulleys 58 to a further conveyor not shown.
Four gas burners 73 project into said combustion section 30 through the rear side wall 20 of the oven, and have nozzles disposed and oriented so as to project (when in operation) their respective flames 73A directly onto the printed metal blanks 50 passing beneath on the conveyor 48, the flames extending across the maximum width of the metal blanks, and being directed forwardly against the direction of the oncoming metal blanks. The vertical separation of the burners from the blanks is such that the hottest part of the burner flames impinges on the upper surfaces ofthe passing metal blanks.
The combustion products arising from said burner flames are drawn upwardly, under the suction created by the circulating fan 44, through entry slots 74 into a recirculation duct 76 disposed in the upper part of said combustion section 30 of the oven, thence into said communicating duct 40 for supply through said circulating fan 44 to said hot air heating section 32 of the oven.
The communicating duct 40 communicates through the outlet duct 78 of said circulating fan 44 with a plenum chamber 80 which is disposed in and extends lengthwise of said hot air heating section 32 of the oven. From the front wall 82 of the plenum chamber a series of hot air nozzles 84 project sideways over the metal blanks 50 carried on the conveyor 48, and direct jets of recirculated hot gases (combustion products) directly downwards onto said blanks, said jets extending across the maximum width of said metal blanks so as to uniformly heat each blank across its whole width.
The nozzles 84 are each provided with adjustable nozzle-forming plates 84B (see scrap view shown in
Figure 1) the positions of which can be adjusted to vary the size, position and orientation of the jets issuing between those plates.
The horizontal wall 86 defining the lower boundary of the communicating duct 40 has provided therein a recirculation aperture 87 and an associated controllable recirculation damper 88 for controlling the recirculation through said aperture 87 and communicating duct 40 of combustion products issuing from said nozzles 84.
These nozzles carry at their respective free ends said cantilever support arms 72 for supporting the upper runs of the conveyor bands.
When the oven is in normal operation, the gas-air mixture supplied to the gas burners in said combustion section is controlled automatically by control apparatus not shown to maintain a necessary temperature in the combustion section (typically up to 650"C) and to provide burner flames of the correct length so that the flames play onto the printed sheet metal blanks 50 carried past them at high speed by the conveyor 48, simultaneously flame-drying the printed material on the blanks and heating up those blanks to cause the solvents in the printed materials to be driven off and burnt.
The heat still carried by the combustion products is used to further heat the metal blanks, by withdrawing those combustion products through the recirculation duct 76 and the communicating duct 40, and then passing them under pressure to the nozzles 84 in the hot air section, from which nozzles they are ejected at high speed onto the blanks as they are carried through the heating section of the oven. Those combustion gases are repeatedly recirculated via said recirculation aperture 87, and via said entry slots 74 in the recirculation duct 76.The temperature of the gases passing through said communicating duct 40 may be boosted by the control burner 42 operating under automatic control so as to maintain the temperature in the hot air section of the oven at a necessary temperature (typically up to 540 C) sufficient to achieve the desired heating of the metal blanks 50 and the drying/curing of the printed materials thereon.
The exhaust fan 38 and damper 36 are controlled to exhaust gases from said combustion section 30 at a rate sufficient to keep the proportion of combustible solvent driven off from said printed material on said blanks in the oven body below a safe level for the avoidance of explosions.
The control gas burner 42 may also be used when starting up the oven, so as to ensure a more rapid buildup to the required oven operating temperature.
A quick drying oven as described above may have a length of some 20 feet (approximately 6 m), and a conveyor speed such as to convey the metal blanks through the oven in approximately 3 seconds.
The gas burner flames are intended to give a rapid initial heat up of the printed metal blanks in the combustion section, whereafter the blanks are intended to soak up further heat in the hot air heating section, thereby ensuring thoroughly uniform heating of the blanks to the desired temperature whilst in the oven.
The burners in the combustion section are adjusted to give a heating effect suited to the drying/ curing characteristics of the particular printed materials carried on the metal blanks.
Ovens built in accordance with the present invention are, in relation to prior art ovens for drying printed materials on sheet metal objects, much more compact, and therefore cheaper to build and install; have much lower heat losses via the oven walls, via the conveyor, and through exhaust gases; and consume much less electrical and thermal energy for comparable heating duty. Moreover, the time to come up to the operating temperature is considerably shorter.
