Definitions

  • This invention relates to apparatus for dispensing solid or viscous materials from a container and, more particularly, to apparatus for dispensing heat softenable materials from drums and shipping containers.
  • the apparatus of this invention may be used to dispense a great variety of different materials, the only requirement being that the material have a viscosity which becomes less viscous or more easily pumpable upon a change of temperature of the material.
  • the dispensing apparatus of this invention is operable to heat a localized top surface area of the material so as to convert it from a solid or an unpumpable viscous liquid to a purnpable less viscous liquid.
  • unpumpable liquids or solids are considered to be those which have a viscosity about 100,000 centipoises. It is these unpumpable liquids or solids which this invention is primarily intended to dispense, although the inventon is equally capable of lowering the viscosity and rendering more easily pumpable those materials which are already pumpable or which have a viscosity below 100,000 centipoises at room temperature.
  • the primary shortcoming of commercially available equipment is the frequency with which the pump or fluid lines become clogged because of the entry of too viscous material into the pump. It has, therefore, been the primary objective of this invention to provide an improved dispensing apparatus which is less subject to clogging.
  • the structure of one preferred embodiment of this invention which accomplishes these objectives comprises a stationary assembly upon which is mounted a movable assembly.
  • the movable assembly is adapted to be lowered into a container of material and includes a follower plate having a seal or wiper around the periphery.
  • the seal engages the interior surface of the container such that the follower plate rests upon and is supported by the top surface of material contained within the drum.
  • the movable assembly also includes a pump having an inlet tube which is located beneath the follower plate.
  • a heating element or platen is located beneath and spaced from the bottom surface of the follower plate and the pump inlet opening.
  • the space between the top surface of the heating platen and the bottom of the follower plate serves as a reservoir from which low viscosity material is pumped.
  • the material enters this reservoir through numerous small vertical apertures in the heating platen, or by passing around the periphery of the heating platen so that only previously heated low viscosity material may pass into the reservoir. Consequently, only material which has picked up a gradient of heat from the heating platen has a low enough viscosity to enter the reservoir and subsequently the pump.
  • FIGURE 1 is a perspective view of one preferred embodiment of a dispensing apparatus which incorporates the inventive concept of this application, and
  • FIGURE 2 is a cross-sectional view taken along lines 22 of FIGURE 1 illustrating the details of the pressure plate and heating platen of the dispensing apparatus.
  • the high viscosity material is a solid glue or so-called hot melt glue which converts from a solid to a viscous liquid upon the application of heat.
  • Other unpumpable room temperature viscous materials for which this invention is particularly well suited include conventional sealants, adhesives, resins and coating materials such as asphalt. While this invention may be used to dispense materials which are viscous liquids and thus pumpable at room temperature, it is most advantageously used to dispense unpumpable solids.
  • the hot melt glue or material 5 is solid at room temperature and must be heated to approximately 230 F. before the viscosity lowers sufficiently to enable the glue to be conveniently used as an adhesive.
  • Some other more exotic adhesives may require that the temperature be raised-to 400 F. or even 700 F. before the material can be dispensed through the pump. If forced through the pump at lower temperatures and thus higher viscosities, the material 5 will require an i-mpractically high internal pump pressure to force flow through the pump or will clog the pump or the guns or outlets through Wll'llCh the material is subsequently directed to the application surface.
  • the dispensing apparatus 10 includes a base plate 15 upon which is mounted a pair of pump elevating motors 16, 17.
  • Each motor 16, 17 comprises a cylinder 18, 19 rigidly attached at its bottom to the base plate 15.
  • a piston is slidably mounted in each of the cylinders and is secured to a piston nod 20, 21 which extends upwardly through the top of the cylinders 18, 19 respectively.
  • a pump support plate 12 extends between and is supported from the piston rods 20, 21 such that the plate moves vertically with the rods 20, 21 under the control of the motors 16, 17.
  • a pump assembly secured to and depending from the bottom of the support plate 12 is a pump assembly, indicated generally by the numeral 22.
  • This assembly 22 comprises a motor 23 drivingly connected to a pump tube 24 by a motor shaft 25.
  • the pump tube ⁇ houses a conventional pumping mechanism (not shown).
  • a plurality of vertical support rods 29 connect the pump tube 24 to the motor 25 and extend between an annular flange 28 at the top of the pump tube 24 and a bottom flange of the pump motor 23. Fluid is pumped or exhausted from the pump tube through an outlet port 31 located at the top of the tube 24.
  • An annular follower 32 is securied to the lower end (see FIG. 2) of the pump tube 24 so as to be vertically movable with the tube.
  • a sealing and wiping element 33 is secured to the follower so as to contact the inside surface of the drum 11 and form a seal between the drum and the follower.
  • the bottom surface of the follower 32 is tapered inwardly and upwardly to provide an inwardly sloping surface35.
  • spacer lugs 36 which support a depending platen or disc 37.
  • the platen 37 is provided with a plurality of vertical apertures 40 and a heating element 41 which is operable to raise and control the temperature of the platen and the surrounding material. It is important to note that the heating platen is spaced below the bottom surface of the follower plate and the bottom inlet 43 of the pump tube 24 so that a reservoir 44 of fluid is located between the top surface of the heating platen 37 and the pump inlet 43.
  • the elevating pistons 20 and 21 are raised to their elevated position at which time a drum or shipping container 11 containing a high viscosity material, such as, for example, hot melt glue, is positioned on the base plate beneath the pump assembly 22. With the drum so positioned, the elevating pistons and 21 are lowered, thereby lowering the attached support plate 12 and pump 22 so as to locate the depending heating platen 37 on the top surface of the solid viscous material 5 contained within the drum.
  • a drum or shipping container 11 containing a high viscosity material such as, for example, hot melt glue
  • the heating platen raises the temperature of the solid material 5 so as to form an interface 46 of melted material in the area between the solid material 5 and the bottom of the heating platen 37.
  • the liquid glue or material 5 passes upwardly through the apertures 40 and around the platen as a consequence of downward pressure on the platen 37, thereby lowering the platen into the drum.
  • the sloping surface on the bottom of the follower in combination with the pressure applied by lowering of the follower plate may force the liquid material toward the inlet 43 of the pump tube 24 or the internal suction of the pump may pull the material into the pump from whence it is pumped through the exhaust tube 31 to an applicator gun or outlet.
  • the heating platen 37 is spaced below the follower 32, the solid or heavy viscous material within the container is prevented from entering the mouth or inlet 43 of the pump tube 24 until it has been heated to the desired viscosity.
  • Continued lowering of the heated platen 37 toward the bottom of the drum preheats the glue or material 5 below it to a liquid which may then flow to the mouth or inlet 43 of the pump 24.
  • the primary advantage of the dispensing apparatus heretofore described results from the maintenance of a reservoir of liquid material above the top surface of the heating platen 37 and below the bottom of inlet opening 43 of the pump 22.
  • the only way in which material may enter this reservoir is through the apertures 40 of the heating platen 37 or around the peripheral edge of the platen.
  • the ratio of the total area of the apertures 40 or gap to the total area of the bottom surface of the heating platen 37 is dhosen to be sufficiently small in relation to the distance the material must move across the heated platen that only liquid material of the desired viscosity and temperature can flow through the apertures 40 or through the peripheral gap into the reservoir 44. Consequently, the viscosity and temperature of the material forced through the pump 24 may easily be controlled so that no solid or semi-solid material may enter and clog the pump or the dispensing apparatus.
  • this invention is also useful for pumping materials which require heating of the material to trigger or initiate a chemical reaction prior to dispensing of the material. Therefore, we do not intend to be limited except by the scope of the appended claims.
  • apparatus for dispensing said material from said container comprising:
  • a movable assembly carried by said stationary assembly, said movable assembly including a follower member adapted to enter the container through the top thereof,
  • wiper means disposed about the periphery of said follower member and adapted to engage the interior surface of the container
  • heating platen carried by and below said follower member, said heating platen being spaced below the bottom surface of said follower member so as to define a reservoir between the top surface of said heating platen and the bottom surface of said follower member, said heating platen having a total area in horizontal cross-section less than the total horizontal cross sectional area of said container such that said matenial can pass upwardly into said reservoir after having been heated,
  • a pump having an inlet tube extending downwardly through said vertical aperture of said follower member, the inlet of said inlet tube being located within said reservoir and above the top surface of said heating platen such that only material which has passed upwardly above said heating platen and into said reservoir may enter said pump inlet tube to be pumped from said container, said pump inlet tube having approximately the same transverse cross sectional area as said vertical aperture of said follower member at the point where said tube passes through said aperture,
  • said heating platen having a total horizontal cross sectional area less than the total combined horizontal cross sectional area of said follower member and said pump inlet so that said material may be forced into said pump inlet by downward force of said movable assembly
