Definitions

  • This invention relates to a coating apparatus for coating a belt-shaped flexible support with a coating solution according to the preamble of claim 1 and a coating method according to the preamble of claim 3, to manufacture photographing photo-sensitive materials such as photographing film and photographic paper, photographic printing plate materials, photo-sensitive sheets, heat-sensitive sheets, magnetic materials, and so forth, and more particularly to a coating method in which a coating width is changed, and an apparatus for practicing the method.
  • the guide board preferably the guide board and the spacer for regulating the width of the slit of the coating nozzle, and the pocket plug for regulating the width of the pocket of the coating nozzle are moved according to the coating width, or exchanged for those different in dimension, and the speed of rotation of the coating solution supplying pump is also changed according to the coating width.
  • the operation of the coating apparatus is suspended for about one hour. During this pause period, the apparatus is lowered in work efficiency, and the coating solution is wasted.
  • This difficulty is serious especially in the manufacture of a photographing photo-sensitive material. That is, if the supplying of the coating solution is stopped during the pause period, then it will be solidified. In order to overcome this difficulty, even if the apparatus is stopped, a small quantity of coating solution is kept supplied to the extent that it is not solidified. This loss of the coating solution during the pause period cannot be disregarded. On the other hand, in order to change the coating width, it may be necessary to remove the coating solution from the coating nozzle; however, if the coating solution is removed in this manner, then it is essential to wash the coating nozzle before the coating operation is started again.
  • One of the apparatuses disclosed by Japanese Utility Model (OPI) No. 120974/1989 is so designed that the end of a base board (or support) is detected to drive a masking bar, and, when the width of the base board is changed, control is so made as to make the coating width constant, or to make the non-coating width constant.
  • Another apparatus disclosed thereby is free from problems that the coating solution leaks to the backup roll, thus lowering the yield.
  • Those apparatuses are still disadvantageous in that they also suffer from the above-described two difficulties, and with a support constant in width, the coating width cannot be freely changed according to the size of a product to be formed.
  • the coating width is changed by exchanging the spacer member; that is, the coating width cannot be changed without suspension of the operation of the apparatus.
  • Document DD-A-269 661 describes a method for adjusting a slit of a coating apparatus in which the flow rate of the coating liquid is constant in time. At the slit exit of the coating nozzle the specific flux of the coating liquid is measured over the whole breadth of the slit, using a spacial energy transport measurement or a flux velocity measurement. From these measurements the cross section of the coating is determined and the widths of the slit is modified such that the cross section of the coating profile is uniform in thickness within the allowed tolerances. In this document no method and no technical hint is given to modify the breadth of the coating, which is designated as coating width in this application.
  • Document DE-A-40 27 515 describes a coating apparatus of extrusion type in which the width of the coating nozzle is defined by fixed spacers made of metallic material. Adjusting the coating width during operation is not possible, resulting in the above mentioned difficulties and disadvantages.
  • Document US-A-4 357 899 describes a web coating apparatus for coating webs with a non-Newtonian coating liquid.
  • the width (breadth) of the coating defined by fixed side edges (dams) and is also influenced by the level of a coating liquid in a coating pool of a coating nozzle. Said level is regulated by a controlled pump rate where the coating width, determined by monitoring means, is used as a control variable.
  • the change of the coating width is only used for pump rate control. Further, the width of the coating nozzle cannot be changed during coating operation.
  • JP-A-57 109 616 a die for extrusion molding is described in which the coating width is changeable with an adjusting device engaged with moveable spacers, defining the coating width.
  • the spacers need a certain minimum thickness, to transfer the force from the adjusting device to the spacers. This minimum thickness of the spacers also limits the size of the slit of the coating nozzle.
  • Document EP-A-0 018 029 describes a device for slide hopper multilayer coating.
  • the delivery slots of the slide hoppers are of different widths, so that the breadths of the individual coating layers are different.
  • For adjusting the widths of the coating during operation of the coater there is no technical realization of adjusting means disclosed.
  • a coating apparatus according to the preamble of claim 1, is described.
  • the apparatus comprises a coating nozzle with adjustable spacers for adjusting the coating width and coating width regulating means engaged with the adjustable spacers.
  • the disadvantage of this apparatus is that the spacers have to have a minimum thickness, to be moveable with the regulating means described. For this reason, the minimum breadth of the slit of the coating nozzle is also limited.
  • a further object of the invention is to provide a coating method in which a period of time required for changing a coating width is minimized, or zeroed.
  • Another object of the invention is to provide a coating apparatus with which a loss of coating solution which otherwise incurs when a coating width is changed is minimized or zeroed, and the coating width can be changed while a coating operation is being performed; that is, even when the coating width is changed, a coating solution layer formed on the support is uniform in thickness.
  • a further object of the invention is to provide a coating apparatus in which the leakage of coating solution from the coating nozzle is minimized, and even when the coating solution has leaked more or less and has been solidified, the coating operation is carried out smoothly.
  • a coating apparatus for coating a belt-shaped flexible support which is continuously run, with a coating solution, supplied through a slit of a coating nozzle, with a coating width regulating member with a spacer adjustable during coating operation, drive means for moving said coating width regulating member in the direction of width of said coating nozzle, where said coating width regulating member further comprises parts which are inserted into a pocket in said coating nozzle, and a seal member for preventing leakage of said coating solution from an inserting hole, through which that part of said coating width regulating member is inserted into said pocket, the coating width regulating member further includes a guide board, and said guide board has a water washing supply hole on the surface which is brought into contact with the opening of said slit of said coating nozzle.
  • a coating method for coating a belt-shaped flexible support which is continuously run in which a coating solution is supplied through a slit of a coating nozzle with a coating width regulating member adjustable during coating operation and with drive means for driving said coating width regulating member in the direction of width of said coating nozzle, whereby a washing water supply is used to prevent solidification of the coating solution in the slit of said coating nozzle, for ensuring the moveability of said coating width regulating member during operation of said coating apparatus, and when a coating width is changed, said coating solution is changed in flow rate so that a coating solution layer formed on said support by said coating solution is uniform in thickness.
  • the seal member is made of an elastic material.
  • the seal member comprises: a cup-shaped head portion equal in sectional area to the pocket; and a barrel portion integral with the head portion which is smaller in sectional area to the pocket.
  • the head portion is radially outwardly spread even with a small force applied to the end face of the barrel portion, thus providing a sealing effect.
  • the guide board has a washing water supplying hole in its surface which is brought into contact with the opening of the slit of the coating nozzle.
  • the coating nozzle has a slit or slits; that is, it includes both an extrusion type coating nozzle, and a slide hopper type coating nozzle. More specifically, the coating nozzle includes not only one having one slit but also one having a plurality of slits for forming a plurality of coating solution layers simultaneously.
  • the coating method and the coating apparatus according to the invention provide for methods of forming extrusion coatings, bead coatings, and curtain coatings.
  • a coating nozzle 2 is used to apply a coating solution to a belt-shaped flexible support 1 which is run continuously.
  • the coating solution is supplied from a coating solution supplying pump P driven by an electric motor M2.
  • a coating width regulating member is used which comprises a part which is inserted into a pocket, and a part inserted into a slit and/or a guide. That is, the coating width regulating member is used to change the flow rate of coating solution according to a given change in coating width.
  • the speed of rotation of a motor M2, which is drive means for moving the coating width regulating member in a direction of width of the coating nozzle is controlled.
  • a control unit may be employed in which a computer specifies a suitable speed of rotation for the motor M2 so that the flow rate of coating solution be proportional to the given coating width.
  • the coating width regulating member comprises at least a guide board 3 in the case of FIG. 1; preferably, the guide board 3, a spacer 4 inserted into the slit of the coating nozzle, and a pocket plug 5 inserted into the pocket of the latter in combination.
  • it comprises: at least a spacer 4 inserted into a slit; preferably the spacer 4 and a pocket plug 5 in combination.
  • a seal member 12 is provided for prevention of the leakage of coating solution from a pocket plug inserting hole into which the pocket plug of the coating width regulating member is inserted. More specifically, the seal member is used to prevent the coating solution from leaking through the gap between the pocket 6 and the pocket plug 5, and it is shaped as shown in FIGS. 1, 3 and 5.
  • the seal member 12 is made of an elastic material such as natural rubber, synthetic rubber, and sponge.
  • An air cylinder 7 is used to push the seal member 12 so that its end face is radially outwardly spread to sealingly close the gap between the packet 6 and the pocket plug 5.
  • the aforementioned drive means for moving the coating width regulating member and the seal member in a direction of width of the coating nozzle operates to move the coating width regulating member according to a given coating width so that the coating width is changed. For this purpose, it transmits the rotation of an electric motor M1 through a screw 8 to a frame 9.
  • the guide board 3 is moved according to a given coating width, and it is generally made of synthetic resin.
  • the guide board 3 is held pushed against the coating nozzle 2 by guide board pushing means, namely, an air cylinder 10; however, when it is required to move the guide board for the purpose of changing the coating width, the pushing force of the air cylinder 10 is reduced or zeroed so that the guide board can be displaced smoothly.
  • guide board pushing means is not limited to the air cylinder 10.
  • the spacer 4 of the coating width regulating member which is inserted into the slit of the coating nozzle, is to prevent the leakage of coating solution from a spacer inserting hole which is located laterally of the slit 11, and to regulate a coating width.
  • the spacer 4 is generally made of metal or synthetic resin.
  • the thickness of the spacer 4 is smaller by 0 to 0.05 mm than the internal dimension of the slit, so that the leakage of coating solution therefrom is minimized.
  • the pocket plug 5 of the coating width regulating member is to prevent the leakage of coating solution from a pocket plug inserting hole which is located laterally of the pocket 6 and through which the pocket plug 5 is inserted into the pocket, and to regulate a coating width.
  • the pocket plug 5 is generally made of synthetic resin.
  • the gap between the pocket 6 and the pocket plug 5 should be minimized to prevent the leakage of coating solution therefrom. However, if the gap is extremely small, then it is necessary to apply a great force to move the pocket plug. Hence, the gap is generally ranged from 0.03 mm to 0.2 mm. With the gap, the leakage of coating solution occurs, and therefore it is necessary to use the seal member 12.
  • the spacer 4 and the pocket plug 5 must be moved together; that is, they should function in association with each other.
  • the material of the pocket plug 5 is not limited to synthetic resin only.
  • it may be made of elastic material such as rubber so that it provides a sealing effect.
  • the seal member 12 is to prevent the leakage of coating solution from the pocket plug inserting hole. Therefore, the seal member may be so modified as to be inserted into the pocket.
  • the seal member is made of elastic material in such a manner that its external dimension is slightly larger than the internal dimension of the pocket.
  • the seal member is formed in such a manner that its external dimension is equal to or slightly smaller than the internal dimension of the pocket, and the end face of the seal member thus formed is pushed against the coating nozzle through a bushing 13 by the air cylinder 7 so that it is spread radially outwardly.
  • the seal member shown in FIG. 1 or 3 is in the form of a flat plate. In order to spread the seal member radially outwardly, it is necessary to apply a relatively great force to it. This difficulty may be eliminated by modifying the seal member as shown in FIG. 5. That is, the seal member shown in FIG. 5 comprises: a cup-shaped head portion which is equal in sectional area to the pocket; and a barrel portion integral with the head portion which is smaller in sectional area than the pocket. The head portion of the seal member is readily spread radially outwardly with a relatively small force applied to the end face of the barrel portion.
  • the seal member When it is required to change the coating width, the seal member may be moved as it is (spread); however, the force applied to the end face of the barrel portion should be reduced or zeroed to move it smoothly.
  • the air cylinder 7 is employed for pushing the end face of the seal member; however, the invention is not limited thereto or thereby.
  • the seal member may be in the form of a rubber balloon, which is used as follows: During the coating operation, the rubber balloon is inflated to provide a sealing effect.
  • the pocket, the pocket plug, and the seal member are circular; however, the invention is not limited thereto or thereby.
  • the movement of the coating width regulating member and the seal member in a direction of width of the coating nozzle may be achieved, for instance, by a servo motor, pulse motor, air cylinder or manual handle.
  • the gap between the slit 11 and the spacer 4 is reduced, and the seal member is employed in the above-described manner, the leakage of coating solution can be minimized.
  • the coating solution may leak from the gap between the slit 11 and the spacer 4 and from around the pocket plug 5, although its quantity is considerably small.
  • the coating solution thus leaked is solidified with time, thus catching the pocket plug or the spacer in the coating nozzle. This results in a difficulty that, when it is required to change the coating width, the pocket plug or the spacer cannot be moved.
  • a water supplying hole 14 is formed in the guide board set above the slit. That is, a washing water is supplied through the water supplying hole 14 to the end of the slit 11 and the end of the pocket to wash them, thereby to prevent the pocket plug or the spacer from being caught in the coating nozzle.
  • the water supplying hole is formed in the guide member; however, it goes without saying that the water supplying hole may be formed in a component other than the guide member.
  • the technical concept of the invention may be applied to a film forming extrusion die, laminating extrusion die, and so forth.
  • a coating solution for forming a photographing photo-sensitive material was applied to a polyethylene terephthalate support 180 ⁇ m in thickness and 1200 mm in width at a coating speed of 100 m/min.
  • the coating width was changed from 1170 mm to 1120 mm.
