Fig. 9 is the plane of the assembled unit of Fig. 6, and it shows the distribution situation of the template radiant heat projector in the adjacent curing oven passage.

Fig. 1 schematically shows the present invention, and it comprises among the non junction conveyer belt 10(figure and representing with chain-dotted line), it loads onto container from loading depot 12, and they are delivered to interleaving agent coating chamber 14, and then delivers to curing chamber 16 with the coating slaking.After this container is sent to debarkation stop 18, and be transmitted machine from this container and take next process to, with the edible running stores of container filling carbonated drink for example, or food article for example catsup, romaine lettuce condiment etc.Container is transported on the non junction conveyer belt in the mode of level, then is that detailed process will describe in detail below through a circuitous up and down route in coating and curing chamber.

Being suitable for a kind of container transfering system of the present invention has seen open in No. 647297 patent application of having addressed.As shown in Figure 2, it comprises that is sent into a conveyer 20, and the latter sent a gathering sill 24 and time control conveying worm 26 backs to arrive conveyance 28 in container in succession.Conveyance comprises that one is positioned each container of sending into for the inlet conveyer 30 within the grid 32 and the container conveyer 34 of a lattice, the latter supports through the guiding of container neck saddle 36 and transfers the container of horizontal positioned state to from erectility, and is located.The shape of the grid of this lattice conveyer and layout are applicable to container shapes shown in Figure 2.Certainly, the grid form of conveyance can be according to the shape correct optionally of different vessels, comprises the cylindrical vessel as addressing in No. the 647297th, the co-pending patent application.

The action of carried in containers machine 10 cooperates with conveyance 28 on time relationship, and it comprises container carrying equipment 38, and the latter is used to put and clamp the openend of container and is keeping basically carrying it under its level and by coating chamber and curing chamber.Each container carrying equipment moves along route A, is parallel to the container that moves by route B on conveyance, all cooperates on time and spatial relationship between the two.In addition, container carrying equipment is all being aimed at each container, as long as extend through two spaces between parallel channels, each toter just can put and clamp the neck of a container.By the time toter has been clamped after the container tightly, and the track of conveyance and airborne carrier just can separate, the toter band container carry out subsequently coating and the procedure of slaking.

The details of container carrying equipment has been seen open in No. the 647297th, co-pending patent application, so for the application, as long as there is certain understanding just enough.Each toter is contained on the non junction conveyer belt 10, it comprises an inner sleeve 40 and outer tube 42, the latter can rotate with respect to inner sleeve 40 by a rotating joint 44, and there is a chuck 46 its end, and its openend can connect with each container.Internal and external casing can be in axial sliding on their center-pole 48.A cam follower 50 on the inner sleeve cooperates so that sleeve pipe moves axially with cam 52.

Container is being loaded in the process of toter 38, cam follower 50 slides on the cam surface 54 of cam 52, thereby toter is seen Fig. 4 against its contained spring 56() elastic force push out vertically.Because the action of chuck 46 and container is to coordinate registration in time, chuck has put container and it has been clamped, shown in Fig. 2 left side.Toter 38A(Fig. 2 that connects with container not) under the elastic force effect of portion's spring 56 within it at cam clearance 58(Fig. 2) locate to be pushed back, and in subsequently coating and slaking flow process, advance along the route different with the toter that has container.

Fig. 4 and Fig. 5 show position and the working order of clamping device in effective travel of band upper container under the effect of cam surface 54 respectively.In Fig. 4, container holding device 38 has been brought container 22 into coating chamber 14, sprays barrier coating 60 by nozzle 62 to it.The position of container in coating chamber is to withstand cam follower 50 by cam surface 54 to be determined.Be contained in belt pulley 66 toter one side, that drive by rotating shaft 68 and drive a driving belt 64.Belt contacts with runner 70 and outer tube 42 and the container in coating chamber is rotated.The rotation of container be for guarantee container accept to spray the coating that comes equably and prevent coating before slaking, hang under or drip.

As can be seen, owing to container is held at neck, so its whole outer surface all can be sprayed coating.In addition, neck itself and internal tank then are cresteds, because these positions do not need coating.

In the prechamber 72 pipe 74 is housed, it sprays into coating chamber with humidity required in the holding chamber and prevent that coating from entering prechamber with one water smoke.Container carrying equipment is to support with cantilevered fashion and vertically move through coating chamber by being contained in guide rail 78 and 80 on the support 82 with horizontal state in Fig. 4 and Fig. 5.

Container holding device 38 is not obtained container from conveyance among Fig. 5, thus between put.Because cam follower 50 contacts with cam disengages, toter has fully moved back and has gone back, and move in prechamber its end 46, and it does not rotate.

Now consult Fig. 1 and Fig. 3: carried in containers conveyer belt 10 passes through coating chamber 14 and curing chamber 16 via the gear that is distributed in diverse location in circuitous up and down mode.The conveyer belt that has container is vertically moving from the top down and is entering coating chamber, and toter contacts the container 22 to rotate the outer tube on each toter and to be clamped in this device outermost end with driving belt 64.The high speed rotation that container changes with per minute 600 to 1000, the rotating speed when they enter and pass through the spraying district is preferably about 800 rev/mins.The rotation of container is evenly distributed on its face coating.Container continues with lower rotating speed rotation subsequently, thus guarantee coating to continue to be evenly distributed on the container and do not drip or hang under phenomenon.

Driving belt 64 shown in Fig. 3 is to be enclosed within on the suitable belt pulley, is driven by motor and reduction gearing 90.

When carrier belt entered slaking (coating) chamber scope, the rotating joint on the toter contacted with driving belt, made each container with very high rotating speed rotation, and for example 800 rev/mins, and accept spraying.Rotation has guaranteed the uniformity of coating on the container.When after expose in the spraying district, container carrying equipment is positioned at outer the contacting to the friction extensible guide 92 that the B point stretches from the A point of coating chamber with its rotating joint with one.Their swing joint later on is enclosed within on the belt pulley 96 and by motor 98 with another root and contacts with the driving belt 94 that belt 100 drives through the B point, and this makes container continue rotation to keep the uniformity of its coating.Required for this purpose container rotating speed is 40 to 100 rev/mins.After coming out from coating chamber, between the C point and D point in its stroke, container is rotated by the 3rd driving belt 104.When they moved with upper and lower circuitous stroke in curing oven, container was being rotated by the rotating speed of driving belt 106 with 40 to 100 rev/mins then.

Extremely shown in Figure 9 as Fig. 1 and Fig. 6, the roughly arrangement of curing oven 16 is: it has several vertical unit 110, and each unit forms a modal sets component of curing oven.Typical compound mode is that each curing oven respectively has a left cell 112 and a right sided cell 114, constitute the entrance and exit of stove respectively, also be first and last slaking passage of stove simultaneously, also have the similar temporary location of several forms 116 in addition.Adopt the design of assembled unit to simplify design, manufacturing, general assembly, operation, maintenance and service work, the flexibility of running also is provided for the producer that uses different vessels simultaneously.Preferably, curing oven comprises several processing sections, each section has its special-purpose atmosphere, temperature and humidity and treatment conditions to adapt to certain given container and paint ingredient, and each section can be regulated separately, and the working conditions change condition of needed curing process is provided for this class container.

A kind of curing oven scheme of the best is shown in Fig. 6, and it comprises the several separate assembled unit, and right sided cell 114 is wherein arranged, temporary location 116 and left cell 112, and they are 118 connections on the composition surface.Left cell provides one from stove 121 downward passage 120 and the passages that make progress 122 that enter the mouth.Each temporary location has passage 126 and 128 up and down, then oriented lower channel of right sided cell 124 and guiding stove export 132 to upper channel 130.

Each assembled unit 110 is the upright box structures of enclosed, and base plate 134 and top board 136 and forward and backward, sidewall 138 are arranged.Have the hole 140 of strip on each assembled unit antetheca, make container carrying equipment 38 and container 22 can enter curing chamber in each unit.Slotted hole 140 extends to another unit from a unit continuously.It has stipulated sinusoidal or the snakelike stroke that container moves.Rear wall is equipped with a door 142 that has pivot 141 and bolt 144, for the inside that enters each vertical channel.

One aspect of the present invention is the maturation process that radiation and Convective Heating are provided for the container that has been coated with coating.Handle required radiation and be decided by the composition of coating, it can be, for example, and ultraviolet and ultrared radiant energy.In addition, when using the convection current slaking, employed working medium (preferably air) is to use radiation source heats.

In the optimum implementation of the present invention, container use during each vertical channel in by stove infrared radiation can and the convection current air come barrier coat on the slaking pet container.Preferably each passage Lower Half is used infrared ray and first half convection current air.Like this, the container that is moving enters the mouth from stove and alternately is subjected to convection current slaking and infra-red curing the outlet.

Therefore, radiation energy 146 has all been equipped in the inside of each assembled unit, the radiation that its coating 148 projection slaking on container is used.As shown in Fig. 7,8 and 9, radiation energy preferably by one be assembled on the support suitable in the stove 152, the adjustable template infrared ray of its position projector 150 forms.The infrared ray projector arranges along the overall height of the Lower Half 153 of stove internal channel basically, and adjusts to and its radiation can be projected the container that passes through.As shown in Figure 8, in order to adapt to given container profile, they are arranged on the camber line layout form of the template projector 150 specially, are following from container bottom 154 to neck the profile of half section of 156 center line one side.Certainly, when each container rotation, its whole outer surface all can be subjected to ultrared irradiation, and therefore the distributional pattern of this infrared emitter provides most economical slaking condition.In addition, can throw selectively to obtain best radiation intensity according to the required maturation process degree of container outer surface different parts after adopting such arrangement.For example, the infrared ray projector of close container neck can be on distance and the side be adjusted upward to mode with the best facing to neck, the coating at this position is generally considered to be more difficult slaking.

The first half 158 of each passage has recycled air stream to pass to provides the convection current maturation process of coating.Can clearly be seen that among Fig. 7 that the convection current air is to send into from the rear wall 164 in each stove district from an air channel 160 by framework 162 supportings.A hair-dryer or fan 166 are housed in the circulation air path, and it is blown into air via the bottom of a total air channel 168 from each passage, and it just can be by radiation source heats like this.Adopt a suitable control system, for example the composite set (not shown) of thyristor and thermocouple is kept each template radiation projector under certain temperature or certain radiation intensity, makes circulating air be heated to the required temperature of slaking.Thyristor is adjusted by certain temperature value, and it regulates the power of the template radiation projector according to the detected temperature of thermocouple, to keep required temperature.The convection current air is upwards to flow in each passage, and it carries out maturation process to the container that enters this passage, flows into circulation air path for constantly sending into curing chamber from blast pipe 170 then, recycles.Flow and the flow velocity of baffle plate 172 for control convection current air is housed in the entrance and exit pipeline of circulating air.Known some barrier coating is very sensitive for the relative air velocity of the container of flowing through.This sensitiveness can be given consideration in the present invention, can adjust these plate washers during by the slaking section at container, makes circulating air be transferred to the flow velocity of various needs.

The relative humidity that some coating is had relatively high expectations is so that mentioned quite high level to the temperature of coating before effective evaporation maturing process begins.For this reason, the nozzle 174 that a series of spraying steams or atomized water spray can be installed also can be contained in according to the needs of maturing process in other selected sections to keep the indoor humidity of each air circulation in predetermined level.High humidity can suppress its evaporation before coating reaches its normal curing temperature.

Curing oven preferably is divided into the section that temperature and humidity has nothing in common with each other according to the different phase of maturing process.Can it be divided into several locellus at inner one or a few the vertical dividing plate 176 of installing of stove.Each section is all installed a circulating air system that separates, so that they can have different temperature, humidity and flow velocity.

During running, container the snakelike stroke that forms by each passage in the curing oven by each the clamping device band on the carrier belt.When container entered curing oven, they were being rotated with sufficiently high rotating speed by toter, keeping the even distribution of coating on the container, and constantly the outer surface of each container were exposed in the infra-red curing cross section of each passage middle infrared (Mid-IR) section.Container at first enters from the convection current slaking district on top, alternately accepts convection current and radiation cure and handles.When leaving the bottom of two adjacency channels, entered convection current slaking district with 40 to 100 rev/mins of containers that rotating speed is rotating, be subjected to the maturation process of convection current air on the top of two adjacency channels.The convection current air constantly circulates via circulation air path and is going back, and holds it in high temperature according to the heating intensity that the infrared ray projector is adjusted.

Passed through after the curing oven, be sent to one through the container of maturation process and transport machine, be sent to following several procedures that container is processed then, for example labelled, can etc.

Obviously, for those those skilled in the art that, can make various modifications to method and apparatus of the present invention, and still not depart from scope and spirit of the present invention.
