Definitions

  • Appl 89381 system includes multiple guns in the form of readily Related Application D: removable cylindrical modules that mount in apertures of a fixed service block or manifold which comlmlatlon-m-pm 0f 775J77, receives the supply lines for the liquid and the gun 70,72S. operating pressurized fluid.
  • the service block and guns have passages which register when the system is [52] U.S. Cl ..222/504 assembled whereby the guns may be easily removed [51] Int. Cl.
  • This invention relates to the application of liquids to surfaces and especially to equipment used to apply beads, ribbons or small unitary deposits of extruded or sprayed material in a desired pattern under high speed production conditions. More particularly, the invention relates to equipment which is particularly suitable for applying heated liquids such as hot melt molten adhesives to various materials such as flat sheets or webs of paper or cardboard of the type commonly used in packaging and adhering a variety of products.
  • heated liquids such as hot melt molten adhesives
  • various materials such as flat sheets or webs of paper or cardboard of the type commonly used in packaging and adhering a variety of products.
  • the invention though, is equally applicable to the application of other liquid materials such as coating materials and paints which may be applied cold or at room temperature.
  • Hot melt liquids are typically of the asphaltic or synthetic resin type and are generally in their solid state at room temperature. When heated to molten form,
  • the molten or liquid hot melt is applied to moving sheet material such as a web of paper or flattened cardboard cartons.
  • the hot melt is applied to filled containers prior to the sealing of the flaps or an end closure.
  • the molten material is used in the coating or assembly .of parts.
  • Another objective of this invention has been to reduce the number of supply lines and service lines modular apparatus with a fluid or air type operatingv system and a pumping system for the viscous liquid to be extruded or sprayed, the apparatus including a fixed service module or manifold defining a passage or manifold for the viscous liquid and a passage or manifold for operating fluid.
  • the passage for the viscous liquid communicates with the pumping system and the passage for operating fluid communicates with a fluid pressure line.
  • One or-more removable gun modules are mounted in the fixed service block module. Each gun has a passage communicating between the viscous liquid passage in the service block module and an extrusion nozzle, and a passage for operating fluid communicating between the operating 7 fluid passage in the service block and a fluid cylinder.
  • the guns are cylindrical and have threads for mounting removed from the service module for service or replacement without disturbing the connections to the service module (air line, electrical lines and hydraulic lines.) Multiple guns may be mounted in the service module in a random pattern (not necessarily in a straight line or geometrical pattern, nor necessarily parallel to each other) so that a pattern of adhesive or other material can be applied to a product or a substrate to fulfill any pattern requirement.
  • Each gun consists of a cylindrical body which contains a ball valve, located in a chamber which is filled with the viscous liquid when the gun is in operation. The valve is opened by a rod which is attached to the ball and passes through a seal which separates the liquid material from an atmospheric vent chamber.
  • the rod continues through a second seal located between the vent chamber and an air cylinder where the rod is attached to a piston.
  • pressurized fluid as for example air
  • the ball is pulled from the valve seat allowing material to flow out of the gun onto the product or substrate.
  • a spring returns the ball to its closed position on the valve seat.
  • An adjustment is provided on the return spring so that the amount of fluid pressure required to actuate the gun is adjustable. Since the force required to actuate each individual gun varies because of differing internal gun fiction forces, the adjustable preload of the spring allows several guns to be adjusted to equalize the pressure required to open each gun. Thus each gun may be adjusted to open at the same time. This is particularly desirable when the product or substrate is moving and registration of the pattern is required.
  • a heater is provided in the service module to maintain the liquid in a molten or low viscosity state until after it leaves the nozzle of the gun.
  • the primary advantage of this modular applicator system is the ease with which it enables multiple modular guns to be arranged in random, closely spaced patterns.
  • the patterns may have points of application spaced as closely as the diameter of a single gun and may be arrangedor configurated in any pattem' in which gun receiving holes may be drilled or machined into the service module or block.
  • Another advantage of this invention is the miniturization which it facilitates Guns constructed in accordance with this invention may be manufactured relatively inexpensively in small sizes or in small diameter cylindrical housings. These small size guns in turn may be used in applications where larger guns would not fit and could not be accommodated.
  • FIG. 1 is a cross sectional view through a modular system incorporating the invention of this application.
  • FIG. 2 is a cross sectional view through the service module taken on line 2-2 of FIG. 1.
  • FIG. 3 is an enlarged cross sectional view through a gun module taken on line 33 of FIG. 1.
  • FIG. 1' there is illustrated a fourgun applicator system for-applying a heated liquid material to a substrate.
  • the'four gun modules or guns 11', l2, l3 and 14 are mounted in alignment in a service module or service block 15.
  • the guns could, though, be mounted out of alignment or in any pattern in the service module 15 but for ease of illustration they are shown in linear alignment.
  • the servicemodule 15 comprises a generally rectangular block through which there extends a pressurized fluid or air passage 16 and a parallel liquid flow passage 17.
  • a pressurized fluid or air passage 16 and a parallel liquid flow passage 17.
  • there is also an atmospheric vent passage 18 extending parallel to and located between the two other passages 16 and 17.
  • the apertures 20- 23 are step bored for reception of the guns 11-14 respectively and each includes a small diameter end section 24, a larger diameter section 25, a still larger diameter middle section 26 and a large diameter end section 27.
  • Aportion of the large diameter end section 27 is threaded, as indicated at 28, for reception of a threaded end section of a modular gun, as is explained more fully hereinafter.
  • the service module or block 15 includes a transverse bore 30 within which there is mounted an electrical resistance heater 31.
  • the flow of electrical current through this heater 3] is controlled by a thermostat 32 mounted in a recess 33 in the face of the block 15.
  • The, recess is covered by a plate 34 bolted or otherwise secured to the service module so as to enclose the thermostat containing recess 33.
  • the service module may be mounted at an applicator station in any convenient manner.
  • the service block 15 is secured to a mounting bracket 38 by bolts 39.
  • the mounting bracket is in turn slideable over a bar 40 to which it is secured by a locking screw 41.
  • the four gun modules 1 1-14 are identical and therefore only one is illustrated and described in detail. As may be seen most clearly in FIGS. 1 and 3, the gun modules are generally circular and tubularin configuration for mounting in the circular cross section apertures 20-23 of the service module.
  • Each gun includes a tubular body 45 through which there extends an axial bore 46. This bore defines a high pressure fluid or air cylinder 47'at one end and a liquid chamber 48 at the opposite end. A small diameter section 49 of the bore interconnects the cylinder 47 and chamber 48.
  • the bore 46 of the body is closed at one end by an end closure cap 50 threaded into an internally threaded end 51 of the bore 46.
  • the opposite end of the bore 46 in the body 45 is similarly closed but by a nose piece 53 threaded into an internally threaded end section 54 of the body.
  • a stepped axial bore 55 extends through the nose piece 53.
  • the larger diameter section of this bore 55 defines a chamber 56 which is open to the liquid chamber 48 of the body.
  • This latter chamber 56 communicates with a small diameter port 57 which isopen to the end of the gun.
  • the nozzle 59 of the gun is threaded onto the end of the nose piece 53.
  • An internal shoulder of the nozzle 53 at the intersection of the small diameter bore 57 and the larger diameter chamber 56 forms a valve seat 63 for a ball valve 64.
  • This ball valve 64 and valve seat 63 together form a check valve 65 for controlling flow of pressurized liquid from the liquid chambers 56 and 48 of the gun. Liquid is supplied to these chambers through a transverse passage 66 inthe body 45 of the gun. When the gun is assembled in the service module or service block 15, this passage 66 registers with the transverse liquid supply passage 17 through which liquid, as, for example, hot melted adhesive, is supplied to the system 10 at high pressure, as, for example, 400 pounds per square inch.
  • the ball valve 64 is mounted upon one end of a piston rod 68.
  • This rod extends upwardly through the small diameter section 49 of the bore 46 and at the opposite end terminates in a threaded section 69.
  • a piston 70 is mounted upon the threaded section 69 of the rod.
  • This piston comprises four stacked rings 71-74. The upper one 74 and the lower one 71 of these rings are threaded onto the section 69 of the rod 68 so as to facilitate adjustment of the piston on the rod.
  • This adjustment of the piston enables the stroke of the check valve to be adjusted by varying the distance the piston is movable from a valve closed position to a position in which the top 87 of the piston 70 contacts the bottom surface 88 of the closure cap 50.
  • An air seal preferably a Teflon seal, is sandwiched between the two middle rings 72 and 73 of the piston. This seal 75 prevents the escape of air pressure from the high pressure cylinder 47 located beneath the piston to a low pressure chamber 76 in the closure cap 50. This latter chamber 76 is maintained at atmospheric pressure through a transverse passage 77 in the cap 50 which opens to atmosphere.
  • An'adjustable preload spring 80 is located in the chamber 76 of the closure cap and bears against one side of the piston 70 so as to force the piston and the ball valve 64 to a closed position.
  • the opposite end of this spring 80 bears against an adjustable seat 81 which is slideable in the chamber 76 of the closure cap.
  • This seat 81 rests against an end 82 of a preload adjustment screw 83.
  • the screw is threaded through a threaded aperture 84 of the closure cap 50 and is secured in an adjusted position by a lock nut 85.
  • Air pressure in cylinder 47 controls opening and closing of the check valve 65.
  • This pressure generally in the form of air pressure, is supplied to the cylinder 47 through a transverse passage 86 which registers with the passage 16 in the service module.
  • High pressure air supplied to the passage 16 effects opening of the check valves by causing the pistons of the guns to move upwardly until the tops 87 of the pistons engage the bottom edge 88 of the caps 50.
  • the springs 80 effect closing of the valves.
  • an air seal 90 is provided around the rod 68 in the air cylinder 47 and a liquid seal 91 is provided around the rod 68 in the liquid chamber 48.
  • the seal 90 includes a resilient Teflon washer 92 held in place by aspring washer 93.
  • the liquid or hydraulic seal 91 also includes a resilient Teflon washer 94 but this seal is held in place by a washer 95 and a backing spring 96. At one end the spring bears against the washer 95 and at the opposite end it bears against an end surface 97 of the nozzle 53.
  • a transverse vent aperture 98 is provided in the body 45 intermediate to the seals 90 and 91. This vent 98 is connected to the through passage 18 in the service module so that it is always open to atmosphere.
  • the four guns 11-14 are individually threaded into the service module and when so assembled, the air passages 86 of the guns register the air passage 16 of the service module. Similarly, the liquid passages 66 register with the liquid passage 17 of the service module and the atmospheric vents 98 register with the atmospheric vent 18 of the service module. Air is prevented from leaking around the exterior of the gun from the passage 16 to the passage 18 by O-ring seals 100 which are mounted in grooves 101 in the exterior of the bodies 45. Two other O-rings 102 and 103 are mounted in grooves 104 and 105 in the bodies 45 to prevent liquid from leaking around the exterior of the body from the liquid passage 17 of the service module.
  • the individual guns are so adjusted by the preload adjustment screw 83 that all four open simultaneously when air pressure is supplied to the gun through the passage 16 of the service module.
  • This air pressure causes the pistons of the guns to move upwardly until the top surfaces 87 of the pistons contact the bottom surfaces 88 of the closure caps 50.
  • This upward movement of the pistons effects the upward movement of the check ball valves 65 and permits liquid supplied to the guns at high pressure (as, for example, 400 psi) in passage 17 to pass through and out of the liquid chambers 55 via the nozzle ports 57.
  • the strokes of the guns are preadjusted prior to assembly of the guns by locating the pistons 70 on the piston rods 68 so that the liquid flows at the proper rate through the check valve 65. After the liquid material has been deposited upon a substrate, the air pressure in passage 16 is opened to atmosphere and the guns are caused to close as a result of the springs forcing the pistons and the attached check valves to a closed position.
  • the service lines to the service module 15 need not be disconnected from the service module. Specifically, the air line to the passage 16, the fluid line to the passage 17 and the electric lines to the heater 31 and thermostat 32 need not be disconnected. All that is required is for the lines to be closed or shut off and the clogged or broken gun to be removed by unthreading it from the mounting aperture of the service module. A new gun may then be inserted by threading it into the aperture and the system restarted. The clogged or broken gun may then be cleaned or repaired without closing down any production facilities while this cleaning or repair takes place.
  • the modular guns may be arranged in any kind of random pattern in a mounting block and may be angulated relative to each other so as to locate the deposits from the gun in even closer spacing than the spacing of the gun nozzle orifices.
