Definitions

  • the present invention relates to a treatment arrangement, and in particular to a treatment arrangement of a type designed to treat a stencil frame fitted with a screen and with the pattern applied in the usual manner.
  • a stencil frame fitted with a screen and with a pattern applied to the screen in the usual manner is referred to in the following specification as a 'stencil'.
  • the treatment arrangement incorporates organs enabling one or more solutions or solvents to be applied to the stencil, organs for the chemical and/or mechanical treatment of the stencil, preferably mechanical treatment with the help of brushes so arranged as to rotate, and organs designed to feed the stencil through the arrangement.
  • the invention finds a particularly suitable application in a treatment arrangement of the type designed for cleaning a stencil after it has been used In a screen printing machine.
  • the treatment arrangement which is the subject of the invention is designed to be capable not only of removing damp and hardened ink, but also of removing pattern material attached to the screen, and also of providing initial treatment of the screen enabling new pattern material to be applied, at the same time washing and rinsing the screen if necessary.
  • the treatment arrangement which is the subject of the invention may be used both with patterns produced on a screen by the direct method and with patterns produced on a screen by the indirect method.
  • the present Invention relates to a treatment arrangement designed for a stencil, said arrangement Incorporating organs for the application to the stencil of one or more solutions or solvents and organs for treating the stencil, preferably mechanical treatment with the help of rotatable brushes, and also a feed organ designed to feed the stencil through the arrangement.
  • a unique feature of the invention is that the feed organ will Incorporate at least one rotatable organ having an Irregular surface, said surface being designed for the purpose of transporting the stencil to be brought Into Interaction with the stencil frame incorporating the stencil.
  • the feed organ shall have a surface with a cross-section in the form of a regular 'n'-sided figure, in which the value of 'n' is lower than 10 and is preferably selected as 4 or 6 , preferably 4 .
  • the feed organ thus Incorporates not only the rotatable organ with the irregular surface , but also a rotatable organ with a circular surface, of which the rotatable organ with the irregular surface is driven.
  • the stencil is fed by these feed devices through rotatable brushes arranged in pairs and rotating in opposite directions.
  • the invention specifically requires a number of rotatable organs with an irregular surface and rotatable organs with a circular surface to be arranged in pairs and to be positioned along a system for conveying the stencil through the entire arrangement, and also requires the rotatable organ with the irregular surface and with a horizontal position for the stencil to be positioned beneath the stencil.
  • the advantages which may be considered to be associated with a treatment arrangement according to the present invention are that the stencil can be transported in a simple manner through the entire treatment arrangement without any slip or without any significant slip between the stencil and the transport device, because of the forces which act upon the stencil during the mechanical treatment of the stencil, in particular when the treatment is by means of rotatable brushes rotating in opposite directions to each other.
  • Figure 1 illustrates a treatment arrangement 1 for a stencil 2 fitted with a screen 3 , said treatment arrangement being Intended to remove ink and pattern material and also to provide Initial treatment enabling new pattern material to be applied to a used screen fitted in a stencil frame for use In a screen printing machine.
  • the stencil 2 consists of a stencil frame 3c , fitted with a screen 3 and with a pattern 3d applied to the screen.
  • Figure 2 shows the pattern 3d to have been applied to one side 3b of the screen 3 .
  • the treatment arrangement 1 incorporates organs for the application to the stencil 2 of one or more solutions or solvents, said organs being in a fixed relationship to the treatment arrangement.
  • Figure 1 shows only a single pipe 4 fitted with a number of jets 5 directed at a brush 6 , although it is obvious that the entire treatment arrangement will contain a number of similar pipes with jets enabling the stencil 2 and also the frame 3c to be given the desired treatment in the different sections.
  • solutions and solvents in this context denote previously disclosed ink and/or pattern removing materials which are also capable of being applied In a previously disclosed manner, e.g. via high-pressure spray nozzles.
  • the treatment arrangement incorporates a number of organs facing in the direction In which the stencil is transported for treating the stencil. It is obvious that the design of the organs will vary depending on the nature of the treatment. Each Individual case may involve purely mechanical and/or purely chemical treatment, or a combination of both.
  • the preferred embodiment relates to mechanical treatment, said treatment being performed with the help of brushes securely attached to the frame but able to rotate inside the frame and arranged In pairs, one above and one below. In this way one brush 6 will interact with another brush 7 , with the brushes being so arranged as to rotate in opposite directions in conformity with all the other brushes included in the treatment arrangement.
  • the brushes must, of course, be positioned above and below the transport track.
  • the typical embodiment of the treatment arrangement 1 is divided up Into five different sections, and each of the sections intended for different treatments can, of course, be allocated Its own particular task.
  • the first section 10 shall be used for the removal of ink, for which purpose not only a first pair of brushes 6 and 7 is required, but also a second pair of brushes 8 and 9 .
  • Materials for dissolving the ink can be applied via the pipe 4 and the jets 5.
  • the second section 11 is specifically intended for rinsing and accordingly Incorporates the necessary organs (not illustrated) for applying the rinsing agent to the stencil.
  • the third section 12 is used for the removal of the pattern, for which purpose two pairs of brushes are required 15,16 and 17,18 .
  • organs (not illustrated) are required for the application of the solvent.
  • the fourth section 13 Is used for a subsequent treatment and for washing the stencil with the help of high-pressure water jets.
  • Section 13 Incorporates rotatable brushes 19,20 .
  • the fifth section 14 Is used for final rinsing and de-greasing, and use is also made here of fixed brushes which are free to rotate 21,22 .
  • the transport device In order to be able to cause a stencil complete with its stencil frame to pass through an inlet orifice 23 and to be transported through the entire treatment arrangement as far as the outlet 24 , the transport device requires to incorporate a number of feed organs.
  • Figure 3 shows one of these feed organs, and this is identical with the feed organ present in section 10 , with the two feed organs present In section 11 , with the feed organ present in section 12 , with the feed organ present in section 13 , and with the two feed organs 25 present in section 14 .
  • Each of the feed organs 25 incorporates at least one rotatable organ 26 with an Irregular outer surface designed for the purpose of transporting the stencil 2 to be brought into interaction with the stencil frame 3c .
  • irregular surface in this context denotes that the surface Is formed with Irregularities or edges intended to be pressed against the stencil frame 3c and to drive-the stencil frame 3c through the sections in the treatment arrangement. Accordingly metal contact is required to be present between the outer surface of the feed organ and the frame.
  • the rotatable driven organ 26 may with advantage have a surface with a cross-section in the form of a regular 'n'- sided figure, for which the value of 'n' should preferably be selected so as to be lower than 10 . This value should really be selected so as to be 4 or 6 , preferably 4 .
  • the feed organ 25 incorporates not only the rotatable organ 26 with an Irregular surface, but also a rotatable organ 27 with a circular surface. Only the rotatable organ 26 need be driven.
  • the stencil frame 3c can now be fed between rotatable brushes 6,7 arranged in pairs and rotating in opposite directions and a number of rotatable organs arranged in pairs, included in the feed organ 25 , with an irregular surface and rotatable organs with a circular surface viewed from the side are arranged along the entire length of the system for conveying the stencil frame 3c through the arrangement 1 .
  • the rotatable organ 26 with an irregular outer surface is positioned beneath the stencil frame 2 and that the rotatable organ 27 with a circular surface Is acted upon by the pressure exerted by a spring 28 , one end of which is attached to the frame 29 of the treatment arrangement and the other end of which is attached to the organ in the form of a roller 27 , said spring pressure 28 holding the roller 27 against the organ 26 .
  • the roller 27 can be raised and lowered against the spring pressure so as to follow any Irregularities.
  • the frame By introducing the frame 3c through the opening 23 the frame will be brought into interaction with the feed organ 25 and it may then be found appropriate to turn the stencil frame 3c with the stencil 3 so that the side 3b becomes the upper side and the side 3a becomes the lower side.
  • the stencil frame 3c will then be fed onwards by the feed organ 25 in section 10 through the brushes 8,9 to the feed organ 25 in section 11 . Rinsing will take place here.
  • the stencil is then fed onwards to section 12 where solvents and solutions are applied In order to remove the pattern, at the same time as feed organs 25 present at that point feed the stencil onwards to section 13 where washing takes place.
