Description
IN LINE PRODUCTION OF SOLID OBJECTS
Technical field o The invention relates to a process for producing solid objects in line.
Background of the invention Processes for producing solid objects in line are widely used, in particular in the ~5 consumer goods industry, for products such as tooth-brushes for example. In general, such solid objects are formed and then printed. In particular, techniques of application of substances onto a selected surface area of such solid objects is particularly used, mostly for printing onto such solid objects. Existing printing techniques are of different kinds. A first kind of printing technique used in the 2o industry consists in printing a large number of labels which are being stored onto large reels, such reels being thereafter fed onto a production line to be glued onto the solid objects. A second kind of printing techniques consists in applying ink directly onto the outer surface of the solid objects, whereby the print itself can be customised so as to indicate for example the date of production or a particular 25 reference number.
The present invention concerns a process for producing a solid object comprising a first step and a second step, the first step consisting in applying a first substance onto a selected surface area by use of first application means, the so selected surface area and the solid object being both in motion relative to the first application means and the selected surface area being solely in contact with the first substance during the first step. Such a process is known from the second printing technique mentioned above, whereby a custom print is applied directly onto a solid object, the letters or numbers of the print being typically formed from a number of black dots.
s Among the advantages of custom printing information directly onto a solid object while in motion relative to the application means is that such information can be different for each solid object produced, and that such printing can occur at high speed on line. Such a process is particularly useful for example in the consumer industry, whereby it is preferable that a solid object is decorated for example.
~o Typically, such custom printing differs from the other existing process of the first kind above, whereby labels are pre-printed independently in a separate process and stored onto reels, prior to being glued in line onto a solid object.
Indeed, in such a process using reels of printed labels, all labels will be identical, and any label will correspond on the line to any solid object. However, such a process using reels of printed labels allows use of labels having relatively high definition graphics, instead of using a limited number of mono-colour dots to reconstitute letters or numbers.
While having these and other advantages, existing processes, and particularly 2o the process of in line custom printing of a matrix of dots or the process of using reels of printed labels, have disadvantages. For example, the process of in line custom printing of a matrix of dots offers a poor definition suitable for printing of simple messages such as a date in one colour but not suitable for printing high definition graphics or designs. Further, the process of using reels of printed 2s labels is not flexible as a change of design of the label will require change of reel, which involves stopping a production line or requires having a double reel supporting system allowing to change reel without stopping the line. In any case, use of reels of printed labels requires storage of any desired kinds of labels, as such labels are not produced directly in line.
It is conventional for solid object for consumer products to carry high quality printed images, both in the form of designs for brand marketing, and information for the consumer such as directions for use. Conventionally such images have been printed onto pressure-sensitive adhesive labels which, after removal of a protective backing material for the adhesive, are applied to the solid object. However, the handling of such labels for accurate application to solid objects at high speed s tends to be difficult, and significant down-time can occur due to backing paper breaking or jamming of labels. Furthermore, the labels must be printed separately on a printing press, which is expensive and time consuming. The label laminate and backing paper are also expensive, and add to the waste stream. Also, factory space must be set aside and an inventory system established to store the labels, ~o and to ensure that the correct label is placed on the correct solid object.
A further disadvantage with the use of labels is that if the decoration artwork changes, any remaining labels must be thrown away, and new labels printed.
From the time the new artwork is approved, it typically takes 4 to 6 weeks to make new printing cylinders or plates, and print and deliver the labels, ready for ~ s application.
As an alternative, images have been printed directly onto solid object by screen printing techniques. However, such techniques tend to be slow, particularly when multi-coloured images are to be printed, and the quality of image that is produced is limited. Typically, only one to four colours are printed at any one time using 2o screen printing, with the result that the complexity of decoration is limited. If further colours are required, this can be achieved by causing the solid object to pass the print station a number of times, but this tends to increase costs dramatically.
Furthermore, when used with non-circular solid object, such as oval solid object or solid object having more complex curved shapes, screen printing tends to be very 2s slow, operating at speeds as low as 50 solid object per minute, and at most solid object per minute.
Furthermore, the screens for use in screen printing tend to take considerable time to manufacture. Such screens also need to be replaced frequently, contributing to maintenance costs.
so Thermal transfer printing techniques have also been used to form images directly onto solid objects. However, such techniques also tend to be slow and, again, tend to result in poor image quality. In addition, pressure and/or heat applied to the solid object being printed by the transfer mechanism may result in damage to the solid object, which is clearly undesirable. Furthermore, the transfer process requires the use of a transfer film which adds unnecessary waste and cost.
It is well-known that good quality images can be achieved using digital printing technology, for instance such as ink jet and laser techniques, and that such techniques are flexible in terms of their application. Ink jet printing has typically been used to print paper or other absorbent materials with water or oil-based inks.
The invention seeks to provide a process for producing a solid object of the 1o above mentioned kind which can provide both flexibility and high resolution in the application of a substance to a solid object, and which can operate in a wide range of speeds for industrial production.
Summary of the invention In accordance with the invention, this object is accomplished in a process of the above kind in that the second step consists in applying a second substance onto the selected surface area by use of second application means after completion of the first step, the selected surface area and the hollow body being both in motion 2o relative to the second application means and the selected surface area being solely in contact with the second substance during the second step, the process taking place at a continuous line speed.
A process in accordance with the invention has a number of advantages. Since it comprises the application of a second substance as well as the first substance onto the selected surface area while both the solid object and the selected surface area are in motion relative to the first or second application means, it allows to obtain both flexibility as the application can be made directly in line, and higher resolution in that more than a single substance is applied onto the 3o selected surface area of the solid object. Due to the improved flexibility, storage such as for example storage of high definition labels onto reels, is significantly reduced, such lowering production costs. Furthermore, flexibility allows for example to reduce wastage of printed labels which are not used, thus being beneficial to the environment.
Detailed description of the invention The process of the invention relates to solid object. By solid, it should be understood that the object is substantially free from empty spaces. Such an object may for example be a toothbrush. It should be noted that the selected surface area ~o my be an integral part of the solid object or may be separate, for example when it is onto a label. Indeed, according to the invention, the solid object could be processed in the following manner: the selected surface area may be onto the label, the selected surface area situated on the label being treated by the process according to the invention prior to being applied onto the solid object.
During ~5 application of the substances on the selected surface area, the solid object is in motion also according to the invention, even if the label is not applied onto the solid object yet. Indeed, both the solid object and the label are on line, the line being such that the label will be applied after printing, for example. The label could also be applied blank onto the solid object and the substances may be applied onto the 2o selected surface area situated on the label as the label is already fixed to the solid object. Furthermore, a label may not be use, so that application of the substance may take place directly onto the solid object.
Preferred hereby would be solid objects made from a material comprising thermoplastic resins.
25 The first step of the process according of the invention consists in applying a first substance onto a selected surface area. Typically, the substance is an ink, which is preferably applied using ink jet technology. The selected surface area preferably covers at least 30 cm2. The selected surface area could be placed for example on a label, or on the solid object such as a toothbrush. Application is made using first 3o application means. Typically. Such means comprise an ink jet head of an ink jet printer, preferably an ink jet head having a plurality of nozzles.

It should be noted that the selected surface area ~o my be an integral part of the solid object or may be separate, for example when it is onto a label.

Indeed, both the solid object and the label are on line, the line being such that the label will be applied after printing, for example. The label could also be applied blank onto the solid object and the substances may be applied onto the 2o selected surface area situated on the label as the label is already fixed to the solid object. Furthermore, a label may not be use, so that application of the substance may take place directly onto the solid object.
Preferred hereby would be solid objects made from a material comprising thermoplastic resins.
25 The first step of the process according of the invention consists in applying a first substance onto a selected surface area. Typically, the substance is an ink, which is preferably applied using ink jet technology. The selected surface area preferably covers at least 30 cm2. The selected surface area could be placed for example on a label, or on the solid object such as a toothbrush. Application is made using first 3o application means. Typically. Such means comprise an ink jet head of an ink jet printer, preferably an ink jet head having a plurality of nozzles.
According to the invention, the selected surface area and the solid object are both in motion relative to the first application means. This does not prevent the selected surface area and the solid object to move separately, as a label may be printed prior to being applied, for example. However, this means that these two s components are in motion on the production line. The relative movement could comprise a component consisting in a movement of the first application means themselves. Indeed, in particular when printing on a non planar selected surface area, it may be preferable to move the application means as well as the selected surface area itself. In any case, the solid object is in motion also, so that, in case of ~ o printing on a label prior to application on the solid object, the solid object is in motion on the line towards the point where application of the label will take place.
Indeed, in a preferred embodiment, the selected surface area is onto the surface of a label, the label being fixed onto the solid object after application of the substances. This differs from another preferred embodiment whereby the selected ~ s surface area is an integral part of the outer surface of the solid object.
The invention also mentions that the selected surface area is solely in contact with the first substance during the first step. This means that there is no friction between any elements and the selected surface area. It should be noted that if the selected surface area is placed onto a label, the label itself may be in contact with for 2o example the solid object. Indeed, the selected surface area is meant to be a two dimensional surface. Such a friction on the selected surface area would for example take place in a screen printing application, the speed of which is not compatible with the process of the invention.
The second step of the invention is similar to the first step and follows the first step.
25 The process according to the invention is taking place at any current line speed depending on the sophistication of the ink jet technology used and the number of heads printing identical colours. This is rendered possible by the continuous movement of the solid object and of the selected surface area and by the absence of friction onto the selected surface area. Further more, the plurality of application so means allows also to progress with a greater line speed, while obtaining a satisfactory application. Preferably, the process takes place at a speed of at least metres per minute, even more preferably at least 20 metres per minute and most preferably at least 28 metres per minute.
In a preferred embodiment, the process further comprises one or more extra steps, 5 the extra step consisting in applying an extra substance onto the selected surface area by use of extra application means after completion of the prior step, the selected surface area and the solid object being both in motion relative to the extra application means and the selected surface area being solely in contact with the extra substance during the extra step. It should be noted that it is preferred that a ~o different substance is applied for each of these extra steps. A most preferred embodiment comprises four extra steps, each of the six substances being a different ink, so that high resolution images may be achieved, as well as high resolution grey scale images with a high contrast.
In a preferred embodiment of the present invention, a process for printing an image onto a selected surface area such as on non-planar solid object surfaces for example, comprises moving a line of solid objects in a continuous manner past an ink jet head having an array of nozzles spaced apart in a direction transverse to the direction of movement of the line of solid objects and through which ink is ejected, 2o and moving each solid objects and/or the ink jet head relative to one another as the said solid object passes the ink jet head, so that during printing the distance between the ink jet head and the solid object surface to be printed remains substantially constant and so that each portion of the said surface passes the ink jet head only once.
2s According to another preferred embodiment of the present invention, an apparatus for printing an image onto solid object surfaces comprises a receptacle for each solid object, conveyor means for moving the receptacles in a continuous manner past an ink jet head having an array of nozzles transverse to the direction of movement of the receptacles and through which ink is ejected, and means for 3o moving each solid object and/or the ink jet head relative to one another as the said solid object passes the ink jet head, so as to maintain during printing a constant distance between the solid object surface to be printed and the ink jet head and so that each portion of the said surface passes the ink jet head only once.
The process and apparatus of the preferred embodiments of the invention are capable of printing, or decorating, non-planar solid object at speeds suitable for commercial production. For instance, in the preferred embodiments of the invention, the process is capable of printing at least 150 solid objects per minute, preferably more than 200 solid objects per minute, and more preferably up to solid objects per minute, while achieving high image quality and avoiding damage to the solid objects.
o Another advantage of the present invention is that it is readily adaptable for use with different shapes and/or sizes of solid objects or labels, foq example, and different artwork and/or text.
Yet another advantage of the present invention is that it is capable of decorating solid objects at reduced cost compared to prior art processes, by for example s eliminating the need for labels and backing papers, transfer films, or printing plates that are expensive to design and maintain.
It should be noted that for example, a solid object having a non-planar surface and having an image printed on that surface is obtainable by a process or by use of apparatus as described above.
2o In the preferred process of the present invention, a line of solid objects is moved continuously past an ink jet head. In the context of this Application, by a line of solid objects it is intended to cover a row of solid objects, or any other arrangement whereby a number of solid objects passes an ink jet head in sequence. The solid objects may be positioned vertically or horizontally during printing,' but preferably 2s they are positioned vertically.
Furthermore, when the line of solid objects is described as moving continuously it is intended to mean that between printing one solid object and the next solid object in the line, the line of solid objects does not stop moving, unless, for example, a change in the process needs to be made, or maintenance of the printing apparatus 3o is required.
During printing it is essential to maintain a small and substantially constant distance between the surface of the solid object to be printed and the ink jet head.
Indeed, in a preferred embodiment, the selected surface area is onto the surface of a label, the label being fixed onto the solid object after application of the substances. This differs from another preferred embodiment whereby the selected ~ s surface area is an integral part of the outer surface of the solid object.
The invention also mentions that the selected surface area is solely in contact with the first substance during the first step. This means that there is no friction between any elements and the selected surface area. It should be noted that if the selected surface area is placed onto a label, the label itself may be in contact with for 2o example the solid object. Indeed, the selected surface area is meant to be a two dimensional surface. Such a friction on the selected surface area would for example take place in a screen printing application, the speed of which is not compatible with the process of the invention.
The second step of the invention is similar to the first step and follows the first step.
25 The process according to the invention is taking place at any current line speed depending on the sophistication of the ink jet technology used and the number of heads printing identical colours. This is rendered possible by the continuous movement of the solid object and of the selected surface area and by the absence of friction onto the selected surface area. Further more, the plurality of application so means allows also to progress with a greater line speed, while obtaining a satisfactory application. Preferably, the process takes place at a speed of at least metres per minute, even more preferably at least 20 metres per minute and most preferably at least 28 metres per minute.
In a preferred embodiment, the process further comprises one or more extra steps, 5 the extra step consisting in applying an extra substance onto the selected surface area by use of extra application means after completion of the prior step, the selected surface area and the solid object being both in motion relative to the extra application means and the selected surface area being solely in contact with the extra substance during the extra step. It should be noted that it is preferred that a ~o different substance is applied for each of these extra steps. A most preferred embodiment comprises four extra steps, each of the six substances being a different ink, so that high resolution images may be achieved, as well as high resolution grey scale images with a high contrast.
In a preferred embodiment of the present invention, a process for printing an image onto a selected surface area such as on non-planar solid object surfaces for example, comprises moving a line of solid objects in a continuous manner past an ink jet head having an array of nozzles spaced apart in a direction transverse to the direction of movement of the line of solid objects and through which ink is ejected, 2o and moving each solid objects and/or the ink jet head relative to one another as the said solid object passes the ink jet head, so that during printing the distance between the ink jet head and the solid object surface to be printed remains substantially constant and so that each portion of the said surface passes the ink jet head only once.
2s According to another preferred embodiment of the present invention, an apparatus for printing an image onto solid object surfaces comprises a receptacle for each solid object, conveyor means for moving the receptacles in a continuous manner past an ink jet head having an array of nozzles transverse to the direction of movement of the receptacles and through which ink is ejected, and means for 3o moving each solid object and/or the ink jet head relative to one another as the said solid object passes the ink jet head, so as to maintain during printing a constant distance between the solid object surface to be printed and the ink jet head and so that each portion of the said surface passes the ink jet head only once.
The process and apparatus of the preferred embodiments of the invention are capable of printing, or decorating, non-planar solid object at speeds suitable for commercial production. For instance, in the preferred embodiments of the invention, the process is capable of printing at least 150 solid objects per minute, preferably more than 200 solid objects per minute, and more preferably up to solid objects per minute, while achieving high image quality and avoiding damage to the solid objects.
o Another advantage of the present invention is that it is readily adaptable for use with different shapes and/or sizes of solid objects or labels, foq example, and different artwork and/or text.
Yet another advantage of the present invention is that it is capable of decorating solid objects at reduced cost compared to prior art processes, by for example s eliminating the need for labels and backing papers, transfer films, or printing plates that are expensive to design and maintain.
It should be noted that for example, a solid object having a non-planar surface and having an image printed on that surface is obtainable by a process or by use of apparatus as described above.
2o In the preferred process of the present invention, a line of solid objects is moved continuously past an ink jet head. In the context of this Application, by a line of solid objects it is intended to cover a row of solid objects, or any other arrangement whereby a number of solid objects passes an ink jet head in sequence. The solid objects may be positioned vertically or horizontally during printing,' but preferably 2s they are positioned vertically.
Furthermore, when the line of solid objects is described as moving continuously it is intended to mean that between printing one solid object and the next solid object in the line, the line of solid objects does not stop moving, unless, for example, a change in the process needs to be made, or maintenance of the printing apparatus 3o is required.
During printing it is essential to maintain a small and substantially constant distance between the surface of the solid object to be printed and the ink jet head.
Otherwise, the position and size of the ink dots produced on the surface of the solid object will vary according to which portion of the surface is being printed, which may in some places lead to smudging of the image, and in others a very faint image, or result in damage to the ink jet head or solid object.
s Generally, prior to printing, the distance between the surface to be printed and the ink jet head will be set at a pre-determined value. Typically, the pre-determined distance will be maintained in the range 0.2 to 4 mm, preferably 0.5 to 2.5 mm, as with larger distances air currents may interfere with the ink jet, leading to poor image quality. This is what is meant by a substantially constant distance in the ~o context of this Application. More preferably, the distance is maintained as constant at 1 mm " 0.5mm.
The pre-determined distance is maintained by moving the solid object to be printed and/or the ink jet head. For instance, the ink jet head may be made to move to follow the profile of the solid object to be printed. However, it is preferred, for ~s simplicity, that the ink jet head remain stationary, and that each solid object is caused to move relative thereto. In this case, it is preferred that, prior to printing, each solid object is arranged so that the leading portion, or edge, of the solid object surface to be printed, in the direction of movement of the line of solid objects, is at the pre-determined distance from the ink jet head. The solid object is then, 2o gradually, rotated about its longitudinal axis to bring each portion of the solid object surface in tum to the pre-determined set distance from the ink jet head as the surface moves past that head, until the trailing portion, or edge, of the solid object surface is at the pre-determined distance from the ink jet head. Forseeably, when solid objects having complex shapes are to be printed it may be necessary to 2s reverse the direction of rotation of the solid object as it passes the ink jet head.
However, it is preferred for the speed of the overall process that when rotating each solid object each portion of its surface that is to be printed passes the ink jet head only once.
The direction and angle of rotation first applied will depend upon the shape of the 3o solid object to be printed, and the shape of any curved path it is made to follow.
For instance, if the solid object is made to move in a substantially straight line and has a surface which is convex to the ink jet head, the leading portion of that surface must first be moved towards the ink jet head, and then gradually away from the ink jet head until the ink jet head reaches the apex, or turning point, of the curved surface, and then the trailing edge of the surface must be moved gradually towards the ink jet head.
5 If the solid object is made to move in a curved path, the solid object may have to rotate either towards or away from the ink jet head, depending upon the respective radii of curvature of the curved path and the solid object surface. Typically, the radius of the curvature of the solid object will be less than that of the curved path, and this requires movement as described above. However, if the radius of 1o curvature of the solid object is greater than that of the curved path, the leading edge of the solid object may first have to be moved gradually away from the ink jet head until the head reaches the apex of the curved surface, and then the trailing edge moved so that this gradually approaches the head.
During printing, the frequency at which ink drops are ejected from the ink jet head 1s may need to be adjusted to compensate for the slight variation in linear velocity of the solid object surface as it passes the ink jet head. The ink jet ejection timing may also need to be adjusted to compensate for the fact that for the most part during printing the ink jet head is not normal to the solid object surface.
Such modifications, however, are well within the expertise of the skilled man.
2o Movement of the solid object relative to the ink jet head in the required manner may be achieved in a number of ways. For instance, a simple servo motor can be used, or a cam mechanism. If a motor is used it will, typically, be controlled by a computer program specific to the size and shape of the solid object being printed, so that a simple change of program will adapt the process for printing a different 2s solid object. This may, therefore, prove more convenient than using a cam mechanism.
If required, the present invention may utilise at least one sensor to monitor the distance between the solid object surface and the ink jet head. Any suitable sensor can be used, for instance an infra-red sensor, a laser sensor, a sonic so proximity sensor. The sensor is in communication with the means for moving the ink jet head and/or solid object relative to one another, allowing adjustment of that moving means if necessary during a print cycle, or after changing over from printing one type of solid object to another, of a different size and/or shape.
It is preferred that during printing each solid object is held within a receptacle on a conveyor or a carrousel. In this case, movement of each solid object relative to the s ink jet head may be achieved by moving its respective receptacle. Each receptacle preferably comprises means for holding its solid object so there is substantially no relative motion between the solid object and its receptacle during the printing operation. Typically, the holding means contacts the solid object at at least one position at its top and its base. Any suitable holding means can be used, one 1o example is to employ a tapered stopper, for insertion into the top of the solid object to a snug fit, and to hold the base of the solid object in a tapered receptacle having substantially the same profile as the base of the solid object. Preferably, the nature of the holding means allows the receptacle to be used with solid objects of different sizes and/or shapes, and to be readily adaptable thereto, thereby allowing 1 ~ conversion from one product line to another, with minimal delay, which represents a significant advantage in present day commercial production.
The process of the invention may use one or a number of ink jet heads, depending upon the complexity of the image to be printed and/or the number of surfaces of the solid object to be printed. Each ink jet head comprises an array of nozzles that 2o are spaced apart in a direction transverse to the direction of movement of the line, or row, of solid objects to be printed. Ink may be ejected from the nozzles in a continuous manner or on a drop-on-demand basis, under digital control, as is well described in the literature. Preferably ink is ejected from the nozzles on a drop-on-demand basis.
25 The number of nozzles and the width of the array are selected according to the image to be printed, as the solid object surface will only make a single pass past each ink jet head. Typically, each ink jet head will have at least 7 nozzles per mm, preferably at least 12 nozzles per mm, which may be arranged in one or more parallel lines. Most preferably, the ink jet head will be capable of printing at least 30 200 drops of ink per inch in the direction of the solid object movement, and preferably 360 drops per inch.
It may also be preferred to utilize multiple grey scale levels, to achieve high quality images and small text quality. Preferably at least four grey scale levels will be used. An example of an ink jet head capable of achieving this is the Xaarjet 1000, supplied by Xaar.
When a number of ink jet heads are used to print differently-coloured inks, and by this we also mean black and white inks, it is essential that these be arranged to achieve good colour-to-colour registration on the final printed solid object.
Typically, the accuracy of registration that is required is such that the error in positioning of differently-coloured dots is 100-400 :m, preferably less than 200 :m, 1o and more preferably less than or equal to 70 :m.
To obtain, in combination, solid block colours, good text, and good photographic images, the process of the invention may be combined with special colour printing techniques. For instance, to achieve maximum flexibility and high quality printing, it is preferred to use so called "Hi-Fi" colour printing using 6 to 7 colours.
This may utilize for example cyan, magenta, yellow ~ and black, plus either i) green and orange or ii) red, green and blue. This expands the colour space available and enables higher quality decoration at relatively low cost, and avoids the need for numerous special colours in order to produce solid colours, as is typical in printing artwork for solid objects.
2o When it is desired to print more than one portion of a solid object surface, for instance diametrically-opposed surface portions or opposite sides of a solid object, after each solid object has passed a first ink jet head it is rotated about its longitudinal axis, for example through at least 90°, to present the next surface portion or side of the solid object to be printed to another ink jet head. For 2s instance, if opposite sides of a solid object are to be printed, each solid object will simply be rotated through approximately 180° between the ink jet heads or sets of ink jet heads. Then, when printing the second surface portion or side, the solid object and/or the ink jet head is again caused to move in the manner described above, in order to maintain a substantially constant distance between the solid 30 object surface and the ink jet head.
Any suitable ink may be used for printing, although certain inks may be preferred depending upon the material from which the solid object to be printed is made.
For instance, for non-absorbent solid objects, eg. plastic, metal and glass solid objects, it may be preferred to use a phase-change ink, such as a hot-melt ink, a heat-fusable non-solvent toner ink, or a radiation-curable ink, typically a UV-curable ink.
In this case, a means for fusing or curing the ink is preferably provided, either after s each ink jet head, if there are a number of these, and/or at the end of the overall printing process. Irrespective of the type of ink used, the solid object surface should have sufficiently low surface energy to enable ink adhesion. This can be accomplished, for example, by flame treatment of plastic solid objects, as is well known in the art.
1o The radiation curable inks may be preferred over those that require drying by heating, as their use is less likely to result in damage to the solid object.
UV-curable inks are particularly preferred, as these adhere readily to plastic surfaces and are durable. The use of such inks in ink jet technology is described in the art.
The present invention is suitable for printing a wide variety of sizes and/or shapes 15 Of solid objects, but is particularly suited to printing solid objects having curved or non-planar surfaces. It is particularly suitable for printing solid objects having surfaces which curve in one sense or direction only, for instance surfaces which are either convex or concave, as opposed to surfaces containing both convex and concave portions. Examples include toothbrushes.
2o The present invention is also suitable for printing solid objects of a wide variety of materials, for instance paper-board, cardboard, plastic, glass, and metal. Its principle purpose, however, is for printing relatively lightweight plastic solid objects, typically of polyethylene polypropylene, nylon, polyester, or polyvinylalcohol, for use in the detergent, beauty-care, cosmetics, paper and food industries, as well as 2s labels, for example. As products in these industries often require updating on a regular basis, and quickly in response to market change or competitor activity, it is essential that solid objects be printed quickly, and that the printing process can be adapted readily to different product lines. The present invention satisfies both these requirements for the first time, and at high speeds similar to filling-line 3o speeds.
Reference is now made to the accompanying drawings:
Figure 1 is a plan view from above of printing apparatus according to the present invention; and Figure 2 is an enlarged orthogonal view of one station of Figure 1, equipped with one embodiment of the solid object receptacle moving means.
s Referring to Figure 1, apparatus 1 comprises a rotating carrousel 2 which carries a number of receptacles 3 which carry solid objects 4 past a series of ink jet heads 5.
Each receptacle comprises holding means (not shown) for its respective solid object.
Each of the receptacles is movable on the carrousel so as to maintain a small and o substantially constant distance between the surface of the solid object to be printed and the respective ink jet head. A UV lamp 6 is provided after each fink jet head, in order to cure the ink printed onto the solid object, and a further UV lamp 7 is provided, if needed, after the final ink jet head, to ensure complete curing of the printed inks. As an alternative to UV lamps, optical fibres may be employed to ~ s convey UV light from a more distant source, thereby conserving space.
The individual solid objects 4 are deposited in their respective receptacles 3 by a conveyor 8 leading from a sorter 9 of conventional type. While on conveyor 8, the solid objects may be subject to other treatments, for instance by a flame treater 10, which acts to reduce surface tension and promote ink adhesion. In addition, a 20 180°-rotation station 11 is provided, to present the other side of the solid object, which has already been printed, to the subsequent ink jet heads.
After printing, the solid objects leave the carrousel and are subject to inspection as to print quality using video equipment 12.
With reference to Figure 2, a solid object 21 is held in a tapered puck 22, with a 25 tapered plug 23, suspended from a frame 24, inserted into the top of the solid object. The puck is supported on a carousel 25 (only a portion of which is shown) which causes the solid object to pass ink jet head 26. Underneath the carousel, motor 27 rotates shaft 28 which is attached to the puck, thereby rotating the solid object in front of the ink jet head. The motor is programmable to cause rotation of 3o the solid object so that the distance between the solid object surface to be printed and the ink jet head is maintained, typically, below 2 mm.
s Generally, prior to printing, the distance between the surface to be printed and the ink jet head will be set at a pre-determined value. Typically, the pre-determined distance will be maintained in the range 0.2 to 4 mm, preferably 0.5 to 2.5 mm, as with larger distances air currents may interfere with the ink jet, leading to poor image quality. This is what is meant by a substantially constant distance in the ~o context of this Application. More preferably, the distance is maintained as constant at 1 mm " 0.5mm.
The pre-determined distance is maintained by moving the solid object to be printed and/or the ink jet head. For instance, the ink jet head may be made to move to follow the profile of the solid object to be printed. However, it is preferred, for ~s simplicity, that the ink jet head remain stationary, and that each solid object is caused to move relative thereto.
