Description

Two split type metal cans are widely used in canned one particularly beer and beverage of numerous food at present.This type of metal can is the typical case with aluminium matter or steel, partly is combined into another pot bottom part that is used for sealing purpose by an integral finish tank body.In system jar process, the outer surface of jar need coat decoration property label (or stamping) and coating varnish is decorateed with prints labels on the protective pot or appearance.In addition, for steel jar and some aluminium can, its outer surface must first last layer coating before printing.At last, Guan inner surface also will be coated with one deck hygienic protection layer.

In order to guarantee the coating quality of protective layer or printing-ink, after applying coating or finishing printing, must be placed on " baking " in the baking oven to can, make coating or printed layers obtain suitable processing.Can after baking is good must be put in the attached cooler of baking oven and be cooled off.For face coat or decoration seal layer and the layer of varnish of handling metal can well, metal can must heat in the caput baking oven.Be equipped with the caput transmission chain of a circulation in the caput baking oven, be equipped with a series of caputs above, in order to articulate can and it was transmitted baking oven and cooler.In typical caput baking oven, transmit chain belt and be installed on the serpentine track; The conveyer belt that carries tank body will be at process baking oven and the baking zone of cooler or the some roads vertical channel in the treatment region on this track.Hang caput conveyer belt elder generation's vertical lifting of tank body and passing through first passage, swiveling head vertically descends and the process second channel then ..., so analogize, leave baking oven and cooler up to tank body.During every passage of tank body process, the spout of arranging along transmission track can spray a series of hot gaseous blasts, and the extraneous adornment coating or the printed layers of tank body are heat-treated.When tank body during, also in a similar manner it is cooled off through subcooler.

Consider from the production efficiency angle, should make can as far as possible promptly pass through baking oven.Under present general operational requirement(GOR), a caput baking oven per minute can be handled and reach 1,000-1, the tank body about 200.

Because the caput that transmits can will put in the openend of can, therefore, when can began to turn around every vertical channel end, centrifugal force can make can wave; And entering next bar vertical channel again in the end of turning, can be subjected to a series of impulse oscillation of flow of process air again.When speed surpasses per minute 1,000-1, during 200 cans, the pulse strength of rocking strength and air-flow might produce the destruction that surpasses degree of admission to can, drops and causes damage from caput such as tank body damage and can.The can that damages can not be used for tinning certainly.For this cause, the caput baking oven that uses at present is subjected to the restriction of above-mentioned speed limit.

According to present caput baking oven design, baking oven is divided into three chambers by internal partition wall: the air feed air compartment of hot-air, baking treating room and return-air air compartment.Internal partition wall comprises that one limits the air feed air compartment and will handle the louver of using air-flow spirt process chamber, and a punching wall that limits the return-air air compartment and accept the processing usefulness gas of process chamber discharge.Louver and punching wall are two substantially parallel planes in opposite directions, and what limited between these two planes promptly is process chamber.Spout shape punching on the louver is arranged in each bar vertical channel of baking oven and on the position of the circuit orbit that plays the binding effect up and down between the vertical channel that replaces.In vertical channel, typical spout arrangement mode be four a branch of, level is separated by, and is distributed in the both sides of vertical channel center line.Each bundle spout is arranged along direction of transfer with certain center distance.The air-flow of these spout bundles group ejection acts on the bottom of jar.In addition, a series of spouts at an angle be distributed in apart from one another by ground with corresponding position, can side on, thereby the hot-air tank skin that leads is reached the purpose of handling tank body.The discontinuous thermal current of spout ejection is injected on the surface decoration layer of can according to the concrete operating position of baking oven, to reach processing intent.The patent applicant measures, the impulse oscillation that the nozzle design of adopting has up to now produced when in fact having aggravated air-flow shooting tank body; Speed is big more, and impulse oscillation is strong with regard to Shaoxing opera.Handle 1 when reaching per minute, 000-1 during the speed of 200 tank bodies, will produce swag phenomenon, causes the more damage of multiple tank head, and more can is from transmitting caput and fall and losing.

In typical conventional design, on the circuit orbit between the vertical channel, be provided with two row's spouts, be positioned at across the vertical partition wall position on the inside and outside path position that transmits center line.Because partly being tank body, action of centrifugal force, circuit orbit be subjected to the area that turbulent flow rocks especially strongly.And existing orifice design can not be strengthened its stability through the can in this location down effectively for fast state.

In the baking oven that adopts at present, usually louver is fixed on the baking oven wall; Rear surface at louver is reinforced with vertical and/or horizontal angle bar, with the pressure up to 18 pounds/square inch in the tolerance air feed air compartment.In some cases, be equipped with the pressure drop wall of one deck and the same length of louver in the louver back.At black this one pressure drop wall of also can not establishing of the baking oven that has; At this moment, above-mentioned reinforcing louver the unique partition member between air feed air compartment and the process chamber.No matter adopt which kind of method, angle bar and the pressure drop plate that may adopt also can make the processing in the baking oven form turbulent flow with gaseous blast with from the stream of emanating that louver sends, cause the instability of tank body, particularly when speed is higher, can cause tank body transmitting rocking on the caput.

At the design and the manufacture view of caput baking oven, the inject process can depends on the specification of specific processed tank body with the arrangement of the spout of thermal current, to reach the optimal treatment condition to the tank body of this specific standard.In addition, baking oven speed also depends on tank body required time of staying in treatment region; And the length of the time of staying is determined by employed coating or printing ink and solvent types.In actual use, the can factory man also can use the can of same oven different size; Therefore, sometimes between tank body size, baking oven speed and nozzle configuration factors serious inharmonious phenomenon can appear.By baking oven the time, both do not had stability, do not reached the uniformity of temperature yet and be in tank body under the inharmonious state.And in case lost the uniformity of temperature, the can body in some zone can overtreating, and can occur the situation of tank body undertreatment in other zones.In addition as mentioned above, the unstability of can also can cause the damage of can body.

For above-mentioned reasons, the speed of the caput baking oven that uses at present is limited in per minute 1,000～1,200 tank bodies.The design of present baking oven is for the tank body of handling a certain predetermined specification, but is used to handle the tank body of all size in actual use; Like this, sometimes will produce the not cooperative phenomenon between tank body and the baking oven.This not cooperative phenomenon makes the tank body through baking oven transmit instability, causes can to handle the damage of bad, burned and can body or decoration.

At present the nozzle configuration of using and the shape of arranging the gaseous blast that is sprayed can make can body produce impulse hunting on the caput and cause and rock and damages transmitting, and particularly prescribe a time limit on arrival rate.

The present invention is intended to release a kind of design of the novel caput baking oven with practical value, and purpose is to reduce harmful tank body swag phenomenon, makes tank body keep stable by baking oven the time; So also just can improve the speed that present per minute is handled 1,000～1,2000 tank bodies simultaneously significantly.

According to design of the present invention, all be equipped with a louvered structure that design is unique on each bar vertical channel of baking oven, the pulsation shaking force that the flow of process air of the tank base of effect and cylindrical sides is produced is minimized.In an ideal form of the present invention, the vertical transmission track of tank body process is equipped with the shutter board of space, therefrom ejects to converge air-flow, forms continuous air curtain, the cylindrical central part that its direction rough alignment is penetrated through the jar of caput conveyer belt.Also be furnished with continuously arranged spray orifice on the shutter board, be used for the form of continuous flow bottom surface with each can of gaseous blast directive.Simultaneously, the effect of polymerization air curtain also can outwards attract the gaseous blast of bottom surface along the tank body side, to improve treatment effect.

Another aspect of the present invention is: a blinds surface of a complete main shutter board puts in one group of passage, and is consistent with the serpentine track of passing by by the can of baking oven; Every the blinds passage all adopts blinds design of the present invention.Main shutter board also has one group of corresponding pressure drop air chamber, is provided to each bar blinds passage respectively.In a most preferred embodiment, six blinds passages are combined into an overall structure together with their pressure drop air chamber, thereby form main shutter board.In addition, the upper circular meander sections with blinds face and pressure drop air chamber of respective numbers also joins together, forms the some of main shutter board, the circuit orbit that main each adjacency channel that defines the serpentine conveyer line is tied.In this design form, the main shutter board that forms one can use bolt or welding and be fixed on the baking oven wall.In actual use, main shutter board is installed on the bottom circular turned section of one group of sub-assembly formula, and the latter defines the shape of the circular channel of each passage lower end.Two partly all have the blinds surface of being with punching up and down, all adopt new-type orifice design of the present invention.Following partly similar to the upper part design, independently pressure drop air chamber all is equipped with.

Owing to designed main shutter board and bottom circular turned district shutter board partly, when entering process chamber with air communication overvoltage sending down abnormally ascending chamber from the processing of air feed air compartment, its flow direction is substantially perpendicular to the preceding blinds face of band punching, thereby reduce the turbulent flow of gaseous blast to greatest extent, to improve tank body stability and to improve the speed of running.

The patent applicant is definite: the shutter board of band spout of the present invention punching can all form the optimization process gaseous blast to the tank body of all size in the certain limit, and can remain to baking oven speed always and bring up to 1,500 jar/minute.These blinds sections can customize separately to reach interchangeability, as long as make the can factory man change the interior dividing plate of baking oven, can carry out optimal treatment to the coating of difform tank body and different requirements.

Therefore, one of target of the present invention is to release a kind of caput baking oven with special gaseous blast design, is intended to change the unnecessary tank body damage of moving and being brought of cannikin, thereby reaches increasing substantially of caput baking oven running speed.

Sign person is a most preferred embodiment of the present invention in the accompanying drawing, in order to illustrate the present invention's principle.Wherein:

Fig. 1 is that the side of the inner section of a caput baking oven is analysed and observe view, mainly illustrates air feed air compartment, process chamber and return-air air compartment.

The sectional view of Fig. 2 for being got along the 2-2 line among Fig. 1 indicated the track of tank body through baking oven.

Fig. 3 for the amplification of being got along the 3-3 line of Fig. 2 sectional view, mark the jet flow pattern that sprays to tank body.

Fig. 4 is the partial sectional view of the amplification of being got along the 4-4 line of Fig. 2.

Fig. 5 is vertical and the partial view of revolution transmission track, illustrate mainly that a preferable spray orifice is arranged and centrifugal force to the effect of the tank body that is transmitted.

Now, see also accompanying drawing, mainly consult Fig. 1 and 2.According to the present invention, caput baking oven 10 have one its be shaped as the closed baking vessel 12 that outside box structure 14 is limited.The antetheca 16 of box structure 14, rear wall 18, roof 20, diapire 2 ¹2, end wall 24.Box structure 14 is by oven frame 26 supportings.Baking chamber 12 is separated into the air feed air compartment 32 that treatment media (normally hot-air) is provided by vertical internal partition wall 28 and 30, the process chamber 34 that the external skin of the tank body that passes through with conveyer belt or printed layers and layer of varnish are handled, and a return-air air compartment 36; Air turns back to recycle gas blower 38 and burner 40 and is reheated in the return-air air compartment.Generally, the caput baking oven is not absolute vertical, but the slight inclination (see figure 1), purpose is that tank body is tangled better on the caput conveyer belt.In the explanation hereinafter, the route that tank body is crossed at the baking oven back warp is known as the track with vertical channel and turning circle of a serpentine.This shows that the main object of this specification is exactly in the baking oven of this inclination to be vertical passage basically.

Tank body C transmitted baking oven by caput conveyer belt 42.Caput conveyer belt 42 comprises a cyclic transfer chain 43, is used for the caput 56 protruding (see figure 3)s of hanging pot body on the chain.Caput is arranged along the longitudinally of chain, and center distance is advisable with 5.25 inches.Chain is serpentine shape, walks around a series of lower sprocket 44 of going up.The serpentine shape chain defines the track (route) that transmits can, i.e. the transmission chain center line 46 that indicates among Fig. 2 and Fig. 5.The feature of chain is to have circular turned district, a series of top and the bottom 50 and 51, and vertical substantially passage 48 is tied.Sprocket wheel comprises inlet sprocket wheel 52, outlet sprocket wheel 53 and middle revolution sprocket wheel 55.Revolution sprocket wheel 55 limits the circular turned zone 50 and 51 between the vertical channel 48.Sprocket wheel 44 is rotatably installed on the wheel hub 49 in a suitable manner; Wheel hub 49 then by hot pressing on axle 54.Axle 54 is driven in a usual manner by the baking oven supporting.Longitudinally along the whole piece chain is equipped with a series of caputs 56, is used to articulate tank body and it was transmitted baking oven.

Interior louver 28 define a series of apart from one another by treatment channel 48, tank body promptly moves in these passages and passes through baking oven.Illustrate: the first passage of baking oven is from inlet sprocket wheel 52, along the through first revolution sprocket wheel 55 of interior blinds metope.Transmit caput chain 43 and extend between above-mentioned two sprocket wheels along advance route one center line 46 1 of tank body, direction of extension and sprocket wheel are tangent.Interior louver comprises circular turned part 58 and 60 up and down, defines the entrance track and a series of middle tow-away zone 50 and 5 that enter first passage ¹1.Shown in Fig. 2,3 and 5, interior louver has the punching 62 of plurality of rows disalignment, is positioned at the both sides of center line 46.These punchings row roughly is stretched in the whole vertical channel 48 between the sprocket wheel 44.In addition, plurality of rows punching 64 and 66 concentric circles that form along each tow-away zone between each vertical channel and arrange.Be not difficult to find that in each circular turned zone, inboard spray orifice 64 is a row; Outside spray orifice 66 then is that the plurality of rows on the vertical channel is offset the extended line of punching 62 in the tow-away zone.Each punching limits the shape of a spout; This spout sprays thermal current and advances process chamber 34 from air feed air compartment 32.In process chamber, gaseous blast sprays to the bottom surface 68 of each tank body C, has handled can on the one hand, plays the effect that transmits on the caput that is fixed on the other hand again.

As shown in Figure 5, can C is subjected to the influence of centrifugal force, so walk around sprocket wheel leaving the straight line treatment channel through tow-away zone 50 and at 51 o'clock, can be subjected to the effect of an outward thrust.And the present invention can make gaseous blast keep even substantially at the arrangement mode of the spray orifice of each turning circle, and the tank body through the circular turned district is formed a kind of stabilization.In addition, when each tank body leaves tow-away zone 50 and 51 and when entering next bar vertical channel 48, the power that tank body is subjected to (active force that comprises the air-flows of the spout 62,64 at centrifugal force and each feeder connection place and 66 ejections) can make the tendency of rocking of the tank body on the caput drop to bottom line.

The spray orifice spread pattern of interior louver has comprised that also the side direction shutter board 70(that being of space converge shape sees Fig. 3 and 5), be positioned at the both sides of the can transmission track 46 of every vertical channel.Every side shutter board 70 comprises an oblique angle top board 74, limits the shape of air chamber 76.The antetheca 78 of air chamber 76 and sidewall 80 make air chamber become in some in louver 28 these integral body.Form acute angle theta between every antetheca 78 and the louver 28.Like this, the antetheca of each piece shutter board of Collaboration just can import the aggretion type gaseous blast (indicating with arrow) upper side 82 to the tank body of process passage in each bar passage.The antetheca of every side shutter board all has punching, and these punching ejection air-flows are handled can; So these punchings have just become spray orifice 84.In the middle of punching on the antetheca should be positioned at, mutual spacing was small enough to form the continuous processing air curtain that sprays to the can sidewall.

Another aspect of the present invention is: every louver 28 is equipped with independent gas vertical compression to fall chamber 86, is limited by the sidewall 90 of punching rear wall 88 and not punching and (sees Fig. 3 ¹With 4).This design makes and flows to the air-flow direction that chamber 86 and punching 62 and 84 fall in the gas vertical compression from recycle gas blower 38 and be approximately perpendicular to louver 28.The sidewall 90 of not punching is stretched in whole vertical lengths of louver; Like this, when producing pressure reduction or air feed air compartment 32 inside generation pressure reduction between each adjacent pressure drop chamber 86, can prevent to the avris blind influx.

Owing to disposed spout 62 and 84, the independently straight plate 88 of gas has been installed on the louver, the pressure and the speed that act on the gaseous blast on each can reach even announcement basically; So just reduced the possibility of can pulsing vibration, it is entered reposefully and passed through baking oven.

As shown in Figure 3, the air-flow of jar end spout 62 ejections is continuous flow basically, and even pressure at the uniform velocity is evenly distributed in the bottom 92 by each tank body of each vertical channel, and it is immersed in the heat treatment air-flow; When being transmitted, tank body do not produce impulse oscillation basically.Simultaneously, aggretion type air port 84 sprays to air-flow the upper side 82 of tank body.Spout apart from one another by, spray simultaneously and form air curtain, spray to tank body upper side and bottom to side, middle part 94.Air curtain is at pressure, and speed and air-distribution aspects are even substantially, and therefore, when transfer rate was accelerated, the tank body that transmits on the caput only can produce small impulse oscillation, or does not produce impulse oscillation.In addition, air curtain can also attract gaseous blast at the bottom of the jar to the side, thereby improves the uniformity of handling.

During through top and the bottom circular turned district, tank body under centrifugal action by from transmitting on the caput to extrapolation (shown in Fig. 3 and 5).The applicant measured already: plurality of rows bottom spout is extended to the circular turned district and at the bottom of the spout 66 that forms can spray to air-flow jar, thereby tank body is steadily advanced, and drops to minimum point rocking oscillation phenomenon.This plurality of rows spout 66 is positioned on the outer concentric circle track of caput conveyer belt center line.In addition, also have row's spout 64, be arranged on the inner concentric circle track.The air-flow that spout on the outside and the inboard track sprays with jar at the bottom of submergence.Because the variation of pressure, speed and the distribution of air, can not produce or produce very small impulse oscillation.

The spacing of bottom spout and side spout 62 and 84 and the selection of direction depend primarily on the shape of tank body and handle the treatment conditions that specific coating needs.As shown in Fig. 3 and 5, the direction of side spout 84 makes the air-flow of its ejection be ejected into the upper part of tank body side, and this partly is a part heavier in the tank body, because this part tank body must the solid operation that firmly just is able to take to be processed into nib and sets up cover.Air-flow changes according to tank skin length and tank body specification with the size of the angle θ at jar end, to form suitable gaseous blast.And the selection foundation of the size of spout and spacing then is the air curtain that is evenly distributed for air-flow is accumulated, to eliminate impulse oscillation.

Bottom surface spout 62,64 and 66 spacing are enough to make one air-flow that is evenly distributed with whole jar of end submergence; Like this, in each vertical channel and circular turned district, jar end, is instantaneous all in the face of the essentially identical gaseous blast of number at each, is immersed in one basic uniform airflow.

Now lift the present invention's one instantiation: an extraneous adornment that is installed in the tank body employing ordinary beer jar of 12 ounces of beverages; Oven speed can reach 1,500 tank body of per minute; The bore of the side spout that uses is 3/8 inch, and center distance is 3/4 inch; Gaseous blast angle θ is approximately 30 °, and jet temperature is 430 °F.Similarly, the bottom surface spout is lined up three row, and disalignment, bore are 1/4 inch, 3/4 inch of center distance.

A further aspect of the invention is: comprise that the main louver in some vertical channels and last circular turned district forms one whole one main shutter board, so that be installed into baking oven en bloc or take out from baking oven.Equally, circular turned district in bottom also forms a whole plate, the baking oven or take out from baking oven of can packing into en bloc.This overall structure can produce above the desirable gaseous blast of describing, thereby makes the outer reason speed of the can by baking oven can reach 1,500 of per minute.As shown in Figure 2, main louver 96 has the upper circular tow-away zone 58 of some vertical channels 48 and respective numbers; The tow-away zone 60 of bottom circular turned plate 98 correspondingly is than more than 58 one of tow-away zones, top, to hold each one of the entrance and exit that enters and leave adjacent main shutter board 96.

See also Fig. 2,3,4 and 5.Sign person is a most preferred embodiment of main shutter board 96 among the figure, comprises six vertical channels 48 and three upper circular tow-away zones 58.Antetheca 28(Fig. 2 and 3 of main shutter board) make every vertical channel 48 all arrange its bottom surface spout 62(Fig. 3 along the center line of the track 48 of transmission chain) and side louvered spout 84 as above-mentioned.Each vertical channel is equipped with an independently pressure drop air chamber 86(Fig. 3 and 4), limited by the pressure drop plate 88 of punching and sidewall 90, upper wall 97 and the lower wall 99 of not punching; The limit wall of these not punchings is together seeing Fig. 1 and 4 from air feed air compartment 32() gaseous blast is by pressure drop air chamber 86 and along importing process chamber with the direction of louver 28 approximate vertical.Adjacent vertical channel is connect by the plate 100 that spaces.

Shown in Fig. 2,4 and 5, each piece master shutter board 96 also comprises three in order to connect the upper circular meander sections of adjacent vertical channel.Each upper circular meander sections has its spout arrangement mode of punching wall 50(as shown in FIG.), diapire 97, the sidewall 102(of punching pressure drop plate 88 and not punching see Fig. 2) and roof 104(see Fig. 4).Roof 104 comprises a top board 106, in order to main shutter board is fixed on the oven frame 26; Also be equipped with a sheath 108, see Fig. 1) in order to clean sprocket wheel and drive shaft assembly 44 and 54(.Sprocket wheel and driving-shaft assembly supporting, guiding also drive driving chain.Processing with air by the pressure drop air compartment and along with the direction of panel approximate vertical by the punching rear wall, thereby flow through spout 62,64 and 66; The roof of not punching, diapire and sidewall have guaranteed that then the processing air follows this route and flow.

The lower end of each main louver ends at a groove 110(under shed and sees Fig. 4), in order to (main louver) is placed on the bottom circular slab 98.

Please referring to Fig. 2 and Fig. 4.The bottom circular slab also is made into the whole plate (Fig. 2 is seen in its cross section) of sub-assembly formula, is connecting the bottom of eight adjacent vertical channels.The panel 112(that bottom circular turned section has punching sees Fig. 4, and it is as indicated above that spout is arranged) and the pressure drop of a punching after plate 114(be used to make processing to arrive process chamber 34 from supplying air compartment 32 by pressure drop air chamber 116 with air).Roof 118, diapire 120 and sidewall 122(see Fig. 2) on do not play punching, define pressure drop air chamber 116, and guarantee that airflow direction by pressure drop air chamber 116 is perpendicular to header board 112.Each section of bottom all is equipped with a sheath 108, in order to cleaning sprocket wheel and drive shaft assembly.Sprocket wheel and drive shaft assembly are below driving chain, and driving chain is guided and driven in supporting.In addition, the groove 124 that is used to install purpose is positioned on bearing cross beam 126, in order to the bottom circular slab is fixed on the oven frame 26.
