Definitions

  • the invention relates to a method and a device for printing objects with a cross-sectional shape that differs from the circular shape.
  • the holder is carried by a chain which is flexible in a plane running parallel to the direction of movement of the object during the printing process and perpendicular to the screen printing stencil.
  • the chain is assigned a guide piece in the form of a curve, the surface of which cooperates with the chain is adapted to the course of the surface of the object to be printed.
  • the holder carried by the chain is moved back and forth between two end positions, the object to be printed being picked up by the holder in one end position and then being guided through the printing station by the holder, whereupon the printed object is removed from the holder in the other end position removed and then the latter is moved back to the first end position for receiving the following object.
  • Screen printing devices for example for printing on hollow objects, in particular bottles and other containers are generally provided with or combined with a transport device for the objects.
  • the objects are brought step by step from a feed position, into which they have been brought, for example, by an upstream conveying device, into the receiving position, in which they are received by the holder, which moves the object through the treatment station, for example a printing station, and into the delivery position releases the printed object, which may be taken over by a subsidy.
  • the screen printing device it is also possible and entirely customary for the screen printing device to have a plurality of treatment stations through which the object is gradually passed in order to be subjected to successive treatments. This can be, for example, a station for dedusting, a further station for flaming, one or more stations in which the object is printed and stations in which the printing ink is dried on the printed object.
  • the length of the transport step between the individual stations will normally be dimensioned depending on the greatest length of the printed image and thus possibly also on the maximum size of the object that is to be printed on the respective device.
  • the transport step can only be fully utilized for the printing process in which objects are provided with a printed image, the extension of which requires a movement during printing which corresponds to the distance of the transport step.
  • the object is transported by a distance which is greater than is technically required for the printing process, with the result that the throughput of the device, that is, their productivity is lower than would be possible with printing technology.
  • the length of the transport step when moving the object without simultaneous treatment is also determined by the transport step required for the printing process when printing the largest possible object for the screen printing device, which is normally larger than required for the actual transport process.
  • the step-by-step transport of the objects from station to station requires the same distances between the individual stations in the area of the same transport device in the case of the conventional transport devices which perform a reciprocating movement.
  • the holder for the object is also carried by a chain, to which guide pieces in the form of curve sections are assigned in the area of the screen printing template, the surface of which interacting with the chain corresponds to the course of the surface of the surface to be printed Object is adjusted.
  • the holder carried by the chain is moved back and forth between two end positions, although there is also the possibility that the end position in which the object is removed from the holder after the printing process has ended coincides with the end position in which the object was previously inserted into the holder.
  • this has the consequence that the entire distance between the two end positions must also be covered during the return movement into this end position after the printing process.
  • the invention is therefore based on the object to modify the method and apparatus of the type described in the introduction so that these disadvantages are avoided.
  • the aim is to be able to carry out the movements of the object that are required for carrying out the printing process in the printing station independently of the transport movements.
  • the length of the transport step can be selected without having to take into account the extent of the movement which the object has to carry out during printing in the printing station.
  • the object is brought into a specific position by the transport device, which corresponds to the receiving position of the holder, and received in this position by the holder and transferred from the holder to the transport device in the same position after the printing process has been carried out.
  • this has the advantage that the lifting movements to be carried out by the transport device, which correspond to the individual transport steps of the objects, can only be determined according to transport-technical aspects. It is not necessary to design the transport stroke of the transport device so that movements to be carried out by the object during the printing process must be taken into account.
  • the holder which carries the object in the treatment station for example the printing station, can be moved with regard to printing requirements only, since this holder has no transport function.
  • Another advantage is that transport of the object on the one hand and positioning it for the printing process on the other hand are also carried out independently of one another.
  • it is necessary to bring them into a position at the beginning of the printing process in which the longer cross-sectional axis of the ellipse generally runs at an acute angle to the plane of the screen.
  • the same applies to the position that the object occupies at the end of the printing process.
  • the positioning of the object before the start of the printing process is effected in the method according to the invention in that the holder is pivoted from the receiving position into the starting position for the movement in the course of which the printing of the object takes place.
  • the holder can be formed in two parts, e.g. B. in such a way that a holder part supports the object at its bottom and the other holder part at the opposite end, for example on the neck of a bottle.
  • the holder for the object is pivotally attached to the machine frame such that the plane in which the pivoting movement takes place is essentially perpendicular to the screen printing stencil and in the direction in which the latter is moved during the printing process. Since there is no direct connection between the movement of the object during printing on the one hand and the transport stroke, the printing speed can only be selected from a printing point of view.
  • the screen printing device shown in the drawing is provided with six stations I, II, III, IV, V and VI, in which the objects are each carried by a slide 10, and a transport device 12.
  • Station II is designed as a printing station and thus with a screen printing stencil 14 and a doctor blade 16. Both parts work together in the manner generally known in the screen printing process.
  • the slide 10 has two horizontal and mutually parallel rails 18, 20 which are arranged at a horizontal distance from one another.
  • the objects to be printed are held by these two rails 18, 20, which can be displaced relative to one another in the direction of arrows 22, 23, when the latter are each in one of the stations I to VI.
  • the objects are bottles whose bodies have a symmetrical elliptical cross section. However, the cross section does not necessarily have to be symmetrical. It is sufficient that the surface to be printed on the respective object is shaped so that it can be rolled on the screen printing stencil.
  • mounting parts 24, 25; 26, 27; 28, 29; 30, 31; 32, 33; 34, 35 attached in pairs so that the bracket parts of each pair are opposite each other.
  • These mounting parts are adapted in the usual way to the shape of the object.
  • the mounting parts 24, 26, 28, 30, 32, 34 which receive the bottom end of the object designed as a bottle, are each provided with a recess 38 designed as a seat, into which the bottom region of the object fits.
  • the mounting parts 25, 27, 29, 31, 33, 35 are designed like a spike so that they can engage in the neck opening of the object designed as a bottle.
  • the mounting parts are attached to the rails 18, 20 with the interposition of consoles 19.
  • the transport device 12 which is arranged essentially below the object carrier 10 having the two rails 18, 20, serves to transport the objects from station I to printing station II and from the latter to stations III and IV to be transported gradually.
  • the transport device 12 is attached in the direction of the arrows 40 and can be pivoted back and forth on the machine frame via pivot arms 21. It essentially consists of a carrier 42 on which three transport brackets 44a, 44b, 44c are detachably attached.
  • the detachable attachment takes place in the embodiment shown in the drawing via tubular intermediate members 46a, 46b, 46c, which are fastened to the carrier 42.
  • An extension 48a, 48b, 48c of the respective transport bracket 44a, 44b, 44c can be inserted into the tubular intermediate members 46a, 46b, 46c.
  • Each of the three transport brackets 44a, 44b, 44c is adapted to the shape of the object with regard to its upper-side boundary surface.
  • the latter is provided on its upper boundary surface on which the object rests with openings which can be connected to a vacuum source, so that a vacuum becomes effective with the consequence that the object is pressed against the transport bracket and thus held in position.
  • the connection to a vacuum source takes place via a connecting line 50, the support 42, the tubular intermediate members 46a-c and the extensions 48a-48c, which are hollow and thus form suction lines.
  • the mounting parts 26, 27, which hold the object located in the printing station II, are generally designed in the same way as the corresponding mounting parts in the other stations.
  • the arrangement in connection with the holding part 26, which receives the base section of the bottle to be printed, is described below with reference to these figures.
  • the holding part 27, which engages in the neck of the bottle and is therefore designed differently, is arranged in the same way and provided with the same drive means.
  • the holding part 26 Since it is used for printing on a bottle 15 with a body which is elliptical in cross section, the holding part 26 is provided with the seat 38 already mentioned for the bottom section of the bottle, which has a corresponding elliptical contour. To achieve a clearer representation, only the elliptical contour of the seat 38 in the holding part 26 is shown in FIGS. 6-9 of the drawing, which corresponds to the contour of the portion of the body to be printed.
  • the mounting part 26 is carried by a toothed segment 52, which is rotatably attached to a mounting 56 via an axis 54.
  • the bracket 56 is height-adjustable on a vertical rail 58.
  • the arrangement is such that the rail 58 is provided with an opening parallel to its longitudinal extension in the form of an elongated hole through which a clamping screw 60 engages, which can be screwed into a threaded bore in the holder 56.
  • the radius of the toothed segment 52 corresponds to the radius of the surface 62 of the object which is to be provided with the printed image.
  • the arrangement is such that the contours of the seat 38 of the holding part 26 are aligned with the pitch circle of the toothed segment 52 in the area which corresponds to the area of the bottle to be provided with the printed image. This is made possible by the fact that the radius of the toothing or, more precisely, the pitch circle of the segment 52 on the one hand and the radius of the surface 62 of the bottle body to be printed on the other hand match.
  • the toothed segment 52 meshes with a gear 64 which is fixedly connected to a shaft 65, on the other end of which a pinion 66 is fixedly attached.
  • the pinion 66 is driven with the interposition of a further gear 67 by a pinion 68, which is fixedly connected to a shaft 70, at the other end of which a pinion 71 is fixedly attached.
  • the latter meshes with a toothed rack 72 which is carried by a toothed rack carriage 74 which executes horizontal reciprocating movements.
  • the rack 72 has an extension 73 which is provided with elongated holes 76 (Fig. 6).
  • clamping screws 77 are provided which engage in threaded bores in the rack slide 74 so that the extension 73 and thus the rack 72 can be attached to the slide 74 at different heights.
  • the shaft 70 is carried by a bearing block 95 attached to the rail 20 (FIG. 7).
  • An arm 96 which can pivot about the shaft 70 and can be locked in its respective position is also attached to the latter and carries the gear 67 and the shaft 65 with the gears 64 and 66.
  • the respective position of the arm 96 results from the diameter and position of the segment 52 and the diameter of the gear 64 meshing with this segment. These are in turn determined by the shape and dimensions of the object to be printed.
  • An arm 78 fixedly attached to the rack slide 74 is provided at its free end with a cam roller 79 which engages in a cam 82 which is attached to a rotatably mounted cam 80.
  • the latter is carried by a shaft 83, on which a gear 84 is also firmly attached.
  • the shaft 83 is supported by a bearing block 85 which is fixedly attached to the rail 20.
  • the drive of the gear 84 and thus the cam 80 takes place via a toothed rack 86 which is carried by a horizontally reciprocable drive carriage 88.
  • the latter from which the back and forth movement for the screen printing stencil 14 is derived, is driven by the main drive of the screen printing device.
  • the drive carriage 88 is guided on a guide 89 attached to the rail 20. It overlaps the rail 20 so that the rack 86 is carried by an extension 87 of the carriage 88 on the side facing away from the guide 89.
  • a roller 93 is attached to the rail 20 and guides the rack 86.
  • the arrangement and course of the curve 82 in the cam 80 and the size of the interacting pinions or gears 71, 68, 67, 66 and 64 or the resulting translation are selected so that the toothed segment during a complete rotation of the cam 80 52 and thus the holder part 26, starting from the first position shown in FIG. 9A, which is located in the middle between the two extreme positions of the holder 26, the tooth segment initially by half of the total path located between the two extreme positions in the starting position for the during the printing process required movement of the toothed segment 52 and thus the holder part 48 is rotated. This position is shown in Fig. 9B.
  • the movement from the middle position into the starting position for the movement required during the printing process corresponds to a little less than 90 ° of a complete rotation of the cam 80.
  • the subsequent movement of toothed segment 52 with holding part 26 from the first extreme position corresponding to the starting position into the second extreme position, 9C corresponds to a rotary movement of the cam 80 of approximately 180 °.
  • the toothed segment 52 with the holding part 26 carried by it is then pivoted back into the middle position according to FIG. 9D during the approximately last 90 ° of the rotary movement of the cam 80.
  • the middle position of the bracket member 26 is shown extended. The two extreme positions are indicated by dash-dotted lines.
  • the screen printing stencil 14 executes a stroke in the course of which the object is printed, which is in contact with the screen printing stencil at least during part of its movement from the first to the second extreme position.
  • the lifting movement of the screen printing stencil and the swiveling movement of the object take place synchronously.
  • An essential aspect of the invention consists in the fact that the object to be printed is in the central position of the holding parts 26, 27 shown in FIGS. 9A and 9D thereof by corresponding displacement of the two rails 18, 20 in the direction of the arrows 23 and 22 respectively is recorded.
  • the now printed object is released again in this middle position by moving the two rails 18, 20 accordingly in the direction of arrows 22 and 23, respectively, so that the receiving position and the dispensing position in the method and the device according to FIG Invention coincide.
  • the device shown in the drawing works in such a way that a bottle which is transported from the conveyor belt 90 in the direction of the arrow 91 to the station I is received there by the holding parts 24, 25. This is done in the manner already described by moving the two rails 18, 20 towards one another in the direction of arrows 23 and 22, respectively. In the course of this movement, the distance between the two mounting parts 24, 25 is reduced to such an extent that the object 15 located in station I is gripped by the two mounting parts 24, 25. The same applies in relation to the other mounting parts 26, 28, 30, 32, 34 and 27, 29, 31, 33, 35 which detect the objects located in stations II to VI in the same way.
  • additional means not shown in the drawing, which are known and not the subject of the invention.
  • station II The object located there is printed in station II.
  • treatments can also be carried out in the other wards.
  • Stations IV to VI are used to dry the printing ink previously applied in station II, this mainly taking place in station V, in which a UV lamp 98 is arranged, which, although to a lesser extent, is directed at the two neighboring stations IV and VI emits.
  • a special transport device 100 is assigned to the stations IV, V and VI, which is provided with two transport brackets 102a, 102b and, moreover, is arranged such that it can be pivoted back and forth like the conveyor device 12.
  • the only difference between the two conveyor devices is that that the two transport brackets 102a, 102b are arranged at smaller distances from each other than the transport brackets of the transport device 12.
  • This smaller distance is possible because these stations are not assigned any facilities that require a certain minimum distance.
  • the latter is the case, for example, in the facilities of the printing station II, in which the screen printing stencil in any case requires a minimum distance to carry out its lifting movements.
  • the smaller distance between stations IV to VI results in the advantage already mentioned that in all three stations the printing ink is dried on the printed bottles.
  • Station VI is followed by an interconnect 104, onto which the bottle located in station VI falls after it has been released from the holding parts 34, 35 by moving the two rails 18, 20 apart in the direction of arrows 22, 23 (FIG. 5) is.

  • the transport devices 12 and 100 are pivoted in the direction of the arrow 40.
  • the middle position during this pivoting movement is shown in FIGS. 4 and 5.

  • the bottle located in the transport holder 44b which had previously been printed in the printing station II, arrives in the station III, where it comes from the holder parts 28 in the course of the following closing movement in the direction of the arrows 22, 23 of the rails 18, 20 , 29 is recorded.
  • the bottle previously positioned in station III is brought into station IV in the course of the pivoting movement of the transport device 12.
  • the holding parts 26, 27 located in the printing station run along empty, since the segments 52 carrying them remain firmly connected to the central drive, which also drives the slide 88. It will generally be advantageous in the printing station, in the presence of two mounting parts 26, 27, which together form the mounting for the object, to assign a mounting plate 80 and a slide to each mounting part, both slides 88 being connected by a cross member that connects the Transfers drive from one sled to the other.
  • Method and device have the advantage that, with a certain cross-sectional shape of the objects, their center or central axes lie in all stations on the same plane, this being true for those stations in which the holding parts are arranged pivotably for the position in which the objects can be picked up or removed from the holder.
  • the adaptation to objects with different dimensions is done by correspondingly adjusting the height of the segment 52, the segment diameter, the diameter of the gear 64 and possibly also the gears connected upstream thereof, the position changes resulting from changing diameters of the segment 52 and gear 64 corresponding pivoting of the arm 96 (Fig. 6) can be effected.

  • the frame carrying the screen printing stencil is also adjustable in height in order to be able to adapt the position of the screen printing stencil to objects with different cross-sectional dimensions.
  • a height adjustment of the stencil frame during a working cycle is generally not necessary, since the elastic deformability of the stencil is sufficient to bring it into contact with the object to be printed by the pressure of the squeegee 16.
