Definitions

  • ABSTRACT A double facer machine for making corrugated 156/210 paperboard is disclosed with means adjacent the inlet end to [51] Int. B31f1/20 prevent severe bodily injury to persons accidentally pulled ⁇ 50] Field of 156/470, into the machine during servicing
  • the means include an ac- 459,462, 205, 206, 207, 208, 209, 210, 590, 591, tuator for releasing a tilt plate and/or the first of a series of heated platens.
  • DOUBLE FACER WITH SAFETY MEANS In the conventional double facer machine a continuous web of single face corrugated board is conductedthrough an apparatus which applies adhesive to the crests of the corrugated medium. The web of single face corrugated board is then brought into juxtaposition with a continuous web of liner board and then conveyed simultaneously over a series of heated platens. The platens heat the adhesive and the corrugated board components thereby modifying the adhesive to bond the single face corrugated board to the liner to produce a continuous web of double face corrugated board.
  • the double facer machine In order to thread up" the double facer machine, the usual practice is for the double facer machine to be running That is, the conveying belt of the double facer machine is moving. The attendant grasps the outer edge of the web, either single face or liner, and leads it into the double facer machine. The web is then moved by friction between its surface and the conveyor belt. At the moment the web begins to move with the conveyor belt, the liner must be released by the operator's hands. If the operator is not agile enough, or the web requires special coaxing, the attendants arms may be pulled into the double facer machine in contact with the heated platens. It is then necessary for a second attendant to stop the machine and aid the first attendant. Since the heated platens are maintained at a high temperature, the arms or hands of a person pulled into the machine may be severely burned.
  • This invention relates to improvements in double facer machines for combining double face corrugated board as set forth above wherein a means is provided to rapidly release a portion of the body of an attendant in the event that it pulled into the machine during servicing.
  • Such means may include a selectively actuable means for release of the tilt plate and/or an actuator means for moving the first of a series of heated platens to an inoperative position.
  • FIG. I is a diagrammatic illustration of the inlet end of a double facer machine incorporating the safety features of the present invention.
  • FIG. 2 is a view in elevation taken along the line 2-2 in FIG. 1 without illustrating the paper board.
  • FIG. 3 is a view similar to FIG. 2 but illustrating another embodiment of the present invention.
  • FIG. 4 is a diagrammatic illustration of circuitry associated with the embodiment illustrated in FIG. 3.
  • FIG. 1 a double facer machine designated generally as 10.
  • the machine includes side frames I2 and 14 which rotatably support roller 16.
  • Roller 16 is one of a pair of rollers around which is disposed the endless driving belt 18.
  • the double facer is provided with a plurality of platens 20, 22, 24 and 26.
  • the platens are preferably heated and may be of the type disclosed in U.S. Pat. No. 2,941,573.
  • Plate 28 is mounted for rotation about the axis of pin 30.
  • Single face paper board 32 has adhesives applied to the crests of the flutes by the adhesive applicator 34 before it is fed into the double facer machine 10.
  • a liner 36 is unwound from roll 38 and fed into the double facer machine ill in juxtaposition to the exposed adhesively coated crests of the flutes of the single face board 32.
  • the liner 36 and single face board 32 are fed into the space between the belt I8 and the curved tilt plate 28.
  • the tilt plate 28 is retained in the operative disposition shown in FIG. I by means of a depending arm 40.
  • a selectively actuable means is provided adjacent and coupled to said tilt plate 28 for causing the tilt plate 28 to move from an operative to an inoperative disposition.
  • Arm 40 is provided with a hole at its lower end through which extends pin 42.
  • Pin 42 is parallel to and supported to actuator shaft 44.
  • Shaft 44 is provided with an actuator button 43 and extends through appropriate guides and seals and boss 45 on the side frame 14.
  • Switch 48 is coupled to the solenoid 50 on valve 52.
  • Valve 52 controls the flow of a motor fluid such as air from the air supply or source 54. when solenoid 50 is activated, it shifts the spool of valve 52 to a position where a motor fluid is no longer flowing from supply 54 to the cylinder 56 and vents the cylinder 56.
  • the actuator means for moving platen 20 from an operative to inoperative disposition includes a piston rod 58 connected to a piston within the cylinder 56.
  • the upper end of piston rod 58 is pivotably connected to the platen 20.
  • the piston rod 58 is permitted to descend and cause the platen 20 to pivot about an axis of pin 60.
  • a remote control means such as a separate manual switch 62 is provided on the side frame I4 adjacent to tile plate 28. When switch 62 is activated, it also actuates the solenoid 50 and causes the spool in valve 52 to shift from the position illustrated in FIG. I to a position where cylinder 56 is vented below the piston.
  • the attendant In the event that the hands and arm of an operator or attendant are pulled into the double facer, the attendant is provided with a safety device immediately adjacent thereto and within his reach.
  • the attendant or his assistant need only actuate the switch 62 or actuator button 43.
  • switch 62 when actuated will merely cause the platen 20 to pivot downwardly about the axis of pin 60. If button 43 is pushed in until pin 42 clears the hole in arm 46, the tilt plate 28 will pivot about the axis of pin 30 and platen 20 will pivot downwardly about the axis of pin 60.
  • FIGS. 3 and 4 there is illustrated a second embodiment of the present invention which is identical with that described above except as will be made clear hereinafter. Accordingly, corresponding elements are provided with corresponding prime numerals.
  • the shaft 44 is provided with the piston 64 fixedly secured thereto intermediate its ends.
  • the piston 64 is disposed within a cylinder 66 with the shaft 44 extending through opposite ends of the cylinder 66.
  • the cylinder 66 is disposed within the frame 14'.
  • Motor fluid such as air from air supply 54' is supplied to the cylinder 66 by way of valve 68 and maintain the shaft 44' in the position illustrated in FIG. 3 wherein the pin 42' extends through the hole at the lower end of the arm 40'.
  • Switch 62 controls the solenoid on valves 52' and 68. When switch 62' is activated, motor fluid is introduced into cylinder 66 to reciprocate the piston 64 to the right in FIG.
  • FIGS. 3 and 4 the embodiment of the FIGS. 3 and 4 is the same as that described in connection with FIGS. 1 and 2.
  • a double facer machine for making corrugated paper board including means for guiding a web of single face board, a tilt plate for guiding a web of liner board juxtaposed to said means for guiding a web of single face board, and a series of heated platens adapted to contact the double face board,
