Definitions

  • the device includes a specially designed housing having an opening sealed by flexible lips through which a tongue member may be moved after separating a predetermined amount of viscous liquid from the reservoir.
  • Alternative arrangements are disclosed for facilitating transfer of the separated viscous liquid to a surface such as that of a moving paper web.
  • the shape of the tongue member can be altered to apply adhesive in a variety of patterns such as intermittent or wavy lines. Uses include tail tying in web winding.
  • Field 07 the in vention.-This invention relates to a liquid metering and dispensing device and, more particularly, to a new and improved device for separating predetermined or metered amounts of relatively viscous liquid from a supply reservoir and for transmitting them to a remote point for application to a surface.
  • viscous liquid has been used to designate, and is intended to encompass
  • the apparatus of the invention can be employed to dispense predetermined amounts of any relatively viscous liquids and to transfer such amounts 'to a remote position.
  • the viscosity of the liquids used can vary depending on the speed of operation of the apparatus as employed. They should generally be more viscous than Water and should demonstrate some temporary tendency to resist fiow or change in shape or arrangement.
  • the present invention represents an improvement in several respects over the device disclosed in US. Patent 3,289,898, issued Dec. 6, 1966 to W. H. Herman.
  • the variety of patterns possible with the device of the present invention is much greater.
  • leakage'around the back of the tongue member, which often occurs after prolonged operation of the Herman device is avoided in the device of the present invention.
  • a particular area in which devices such as the above have been employed and in which the above problems have become important is that of the paper industry with regard to transferring adhesive to a moving web of paper coming from a parent roll of paper or from a paper manufacturing machine for the purpose of attaching the tail end of a predetermined length of paper to the roll upon which the predetermined length has been wound.
  • This process is often referred to as tail tying.
  • it has been found advantageous to apply adhesive or glue in a continuous or intermittent line transversely across a rapidly moving paper web adjacent to or with reference to high rate of speed, that is, where the velocity of the paper web is 1200 feet per minute and higher, and on a socalled continuous basis.
  • the invention provides a housing having two converging walls and spaced'side walls defining a chamber for containing a supply of a viscous liquid such as adhesive or glue.
  • the converging walls are arranged to intersect along a line of intersection of the plane of one converging wall with the plane of the other converging wall at an angle of less than about 150.
  • Each of the converging walls have a gate portion adjacent the line of intersection.
  • the gate portions adjoin each other along the line of intersection and are disposed in sealing engagement with one another in a closed position but are movable out of contact with one another upon application of force in order to permit the separation and removal of a predetermined amount of viscous liquid from the chamber.
  • a tongue member is disposed within the chamber between the converging walls.
  • the surface of the bottom edge of the tongue member is substantially parallel to the line of intersection between the converging walls and extends between the spaced side walls of the housing. At least a portion of this surface is in a plane angularly disposed to the planes of the converging walls.
  • the tongue member is arranged for movement so that the bottom edge surface is reciprocably movable from a first position wherein the surface is disposed within the chamber, spaced from, and out of contact with, the converging walls, through a second position wherein the boundries of the surface are in contact with the converging walls thereby defining a cavity which contains a metered amount of viscous liquid, to a third position wherein the surface is disposed outside of the chamber upon deflection of the gate portions and carries thereon the metered amount of viscous liquid.
  • Actuation means are operably connected to the tongue member to provide a means for reciprocally withdrawing the tongue member toward and away from the line of intersection of the converging walls.
  • the tongue member has a bottom edge surface comprising a plurality of spaced-apart areas of greater width connected to one another by areas of lesser or negligible width. It will become apparent that a large variety of patterns can be arranged with this type of device so long as the gate portions of the converging walls are sufficiently flexible to sealingly engage opposed surfaces of the tongue member as it passes between them. It has been found possible to deposit flexible adhesive on a surface in an arcuate or wavy line utilizing this principal but with a tongue member having a bottom surface of different configuration.
  • the entire viscous liquid metering and dispensing device may be advanced by an actuation means so that the bottom edge surface of the tongue member contacts a moving web at the desired moment. In this manner, the measured amount of viscous liquid is transferred and the web receives an application of a metered amount of viscous liquid on the desired portions or areas.
  • Another method of transferring the amounts of viscous liquid involves an associated transfer means such as the transfer bar which may be conveniently carried upon the surface of a rotatably mounted cylinder.
  • the transfer bar is advanced by rotation of its carrying cylinder into interference with the bottom edge surface so as to remove the predetermined amount of viscous liquid from the surface and carry it upon the transfer bar.
  • the transfer bar is arranged to contact a surface such as that of amoving web so as to transfer the viscous liquid to the web at the desired point.
  • FIGURE 1 is a perspective view of a viscous liquid metering and dispensing device of the invention
  • FIGURES 2, 3 and 4 are partial sectional views taken along line 2-2 of FIGURE 1, and progressively illustrate the manner of operation of the device of FIGURE 1,
  • FIGURES 5 and 6 are bottom views of alternative embodiments of the device shown in FIGURE 1, arranged to transfer predetermined amounts of viscous liquid in intermittent and wavy lines, respectively,
  • FIGURE 7 is a schematic sectional view of a metering and dispensing device and associated transfer means for transferring a measured amount of viscous liquid to a moving web
  • FIGURE 8 is a schematic sectional view of a metering and dispensing device movable by an associated actuation means into contact with a moving web.
  • FIGURES 1 through 4 of the drawings there is shown a housing, indicated generally by reference numeral 1t which includes two converging walls 11 and 12, respectively.
  • Converging walls 11 and 12 are arranged to intersect along a line of intersection of the plane of converging wall 11 with the plane of converging wall 12 at an angle of about 60.
  • Two spaced side walls 13 connect with converging walls 11 and 12 to define a chamber 14 within which a viscous liquid is retained.
  • the angle of intersection of the planes conveying walls 11 and 12 may be varied within wide limits to define a chamber of different dimensions and difierent configuration. The maximum practical angle of intersection has been found to be about 150. Beyond this amount the chamber is so shallow as to occupy too much space. More preferred embodiments employ a narrowed chamber formed by a lesser angle of intersection.
  • Converging walls 11 and 12 have flexible portions 15a and 15b adjacent the line of intersection between their planes. Portions 15a and 15b serve as gate portions or members to sealingly close off the bottom of the chamber 14. Portions 15a and 15b adjoin each other along the line of intersection and are disposed in sealing engagement with one another when in a closed position but are adapted for movement out of contact with one another upon application of force as a result of their flexibility.
  • the portions or strips 15a and 15b may be comprised of any type of flexible resilient material such as rubber which may be bent from one side or another out of the plane of their respective converging wall 11 and 12 upon the application of force. Portions or strips 15a and 1511 are sealingly attached to converging walls 11 and 12 by a series of bolts 16. The ends of flexible portions 15a and 15b sealingly abut and engage the inside surface of each of the spaced side walls 13.
  • valve 19 which governs the operation of a double action air cylinder 20.
  • the piston 21 of air cylinder 20 is operably'co'nnected to the end of tongue member 17 opposite bottom edge surface 18.
  • Valve 19 connects air line 22 to air cylinder 20 through feed lines 23 and 24, alternatively.
  • the operation of valve 19 may be performed by hand or may be controlled by connecting it with the operation of other equipment such as a web handling machine or a continuous winding machine for rolled paper products in a manner which is well known and understood in the art and employed with like equipment.
  • other types of actuation means could be employed.
  • a viscous liquid such as glue may be circulated through the chamber 14 within housing means by means of feeding it into chamber 14 through one or more inlets 25 on housing means 10 and withdrawing it from chamber 14 through one or more outlets (not shown) on the opposite end of housin means 10.
  • the housing means 10 may be fitted with a lid (not shown) which sealingly covers the top portion thereof and is in frictional contact with the moving tongue member 17.
  • the device of the invention differs in many important respects from that disclosed in US. Patent 3,289,898.
  • the tongue member 17 by disposing the tongue member 17 in a plane which intersects the planes of converging walls 11 and 12, it is possible for portions of converging walls 11 and 12 to have wiping contact with'the opposed faces of tongue member 17 as it moves outwardly from chamber 14. This prevents the leakage often experienced in the device disclosed in the earlier patent after prolonged operation.
  • Such leakage :across the device is extremely harmful to paper products being wound into rolls since it results in-adhesive dripping on the paper web at undesired times. It also results in excessive amounts of adhesive being applied which causes many plies to be bonded together and ultimately wasted.
  • FIGURES 7 and 8 illustrate two alternative methods for handling the metering amount of viscous liquid after its separation from the parent supply in order that it may be transferred to the surface of a work piece such as glue to one surface of a moving paper web.
  • FIGURE 7 contemplates employing with the viscous liquid metering and dispensing device a separate transfer means which in the embodiment shown comprises a rotatably mounted cylinder 33 positioned between the bottom edge surface 18 of a tongue member 17 of a metering device and the surface of a moving paper web 34 which represents the surface of a work piece to which viscous liquid is to be applied.
  • Web 34 is supported in partial wrapping engagement with the surface of a rotatably mounted supported roll 35.
  • Cylinder 33 has a protuberance 35 extending outwardly from its surface which protuberance extends longitudinally from one end of roll 33 to the other.
  • FIGURE 8 illustrates another embodiment of apparatus involving the metering and dispensing device shown in FIGURE 1 for transferring the measured amount of viscous liquid contained on bottom edge surface 18 to a desired surface.
  • an actuation means such as double action air cylinder 38 is attached to converging wall 11 of the housing 10 of a metering and dispensing device and is arranged to advance and withdraw the entire metering and dispensing device to a position where the bottom edge surface 18 of an outwardly extending tongue member 17 containing a metered amount of viscous liquid thereupon would contact a desired surface such as the surface of a moving paper web 34 at a predetermined time.
  • a moving paper web 34 could be supported in partial wrapping engagement-with a rotatably mounted support roll 35.
  • a valve 39 is arranged to control the operation of double action 'air cylinder 38 by means of air from line 40 fed through line 41 or line 42. Air cylinder 38 would advance and withdraw the bottom edge surface 18 into contact with the surface of the moving web 34 at a predetermined time thereby accomplishing viscous liquid transfer.
