  • the type of article for which the machine is adapted may be broadly characterized as a pad of the kind typified by any of several well known commercial products such as disposable diapers, paper napkins, paper towels, sanitary napkins or the like.
  • the machine has been developed to be used in the stacking and packaging of pads such as the disposable diapers of the type described and claimed in U.S. Pat. No. Re. 26,l5l Duncan et al, issued Jan. 31, 1967, which is commonly owned by the assignee of the present invention. While the machine will be described in connection with the handling and packaging of disposable diapers, it will be understood that this does not form any limitation on the scope of the invention or is it to imply that the machine is not capable of handling other kinds of articles having similar characteristics.
  • FIG. 9 there is illustrated a typical disposable diaper 10, this being the preferred form of pad handled by the machine.
  • the diaper is of the type having box pleats and will be familiar to persons of ordinary skill in the art who will be acquainted with the teachings of the aforesaid Duncan et al patent.
  • the box pleats are formed and folded along the side edges of the diaper whereupon the diaper 10 is folded on itself in the middle portion thereof to form a nose 1] after the diaper is folded into the configuration illustrated in FIG. 9.
  • Diapers in the form of FIG. 9 are forwarded to the machine of the present invention from a final folding mechanism of a diaper converting machine, the movement of the diaper 10 being such that the nose 11 is foremost in its path of movement.
  • the diapers 10 pass between the rolls l2 and 13 forming a portion of the final folding mechanism of the diaper converting machine whereupon they are delivered in single file order to an infeed conveyor illustrated generally at 14.
  • the infeed conveyor 14 consists of a first section 15 and second section 16, there being a diverter plate 17 interposed between the sections 15 and 16.
  • the infeed conveyor 14 is supported by the frame 18 which is used as a rigid support for the several mechanisms of the entire machine.
  • the first section 15 of the infeed conveyor 14 comprises a pair of opposed forwarding belts l9 and suitably supported and driven to receive the diapers 10 with their nose 1] foremost and move them forward at a speed matched with the speed at which they are received from the rolls 12 and 13.
  • the forwarding belts l9 and 20 are backed by the compression rolls 19a and 20a spaced apart such that the belts 19 and 20 also impart a desired amount of compression to the folded diaper 10.

  • the source of motive power for rotating the pad cycle shaft 24 may be provided by an independent power unit or it can be directly coupled to the diaper converting machine.
  • the shaft 24 drives the belts 19 and 20 by the use of a conventional chain and sprocket drive mechanism including the right angle gear box 25.
  • the forwarding belts 21 and 22 may be driven at matched speed with the belts 19 and 20. However, they are preferably driven at a slightly slower speed, about l5 percent slower, so that they can properly insert the individual diapers into the pad wheel 23.
  • the forwarding belts 21 and 22 are also driven from the pad cycle shaft 24 by the use of a conventional chain and sprocket drive mechanism which includes a variable speed drive 26 and a right angle gear box 27.
  • the variable speed drive 26 may be used for fine adjustment of the speed of the belts 21 and 22 to permit variation of the insertion speed of successive diapers into the slots 28 in the pad wheel 23.
  • the forwarding belts of the second section 16 are preferably driven at a somewhat slower speed than those of the first section 15, this presents no problem of buckling or puckering of the diapers 10 as they are transferred across the diverter plate 17 from the first to the second section since the distance between the exit nip of the first section 15 and the entrance nip of the second section 16 is equal to or slightly less than the length dimension of the thick absorbent core portion of the diaper 10.
  • the diaper 10 is fully supported by the diverter plate 17 as it moves from the first section 15 to the second section 16 without any substantial effect on the diaper itself.

  • the pad wheel 23 is turned continuously by means to be described such that the slots 28 are sequentially aligned with the exit nip of the forwarding belts 21 and 22. Thus, successive slots 28 are moved into diaper receiving position such that diapers 10 can be inserted therein.
  • the pad wheel 23 may comprise a pair of spaced similarly configured wheel elements 23-23 mounted on a common shaft 29 and driven continuously by the pad cycle shaft 24 through a conventional chain and sprocket drive mechanism including the gear box 30.
  • Means are provided to remove each individual diaper 10 from the successive slots 28 in the pad wheel 23 and thereby form a stack 31 containing a predetermined number of diapers 10 standing on their noses ll.
  • an obliquely mounted stipper plate 32 is provided such that it intercepts the path of movement of the slots 28 in the pad wheel 23 (FIG. 7').
  • the nose 11 of each diaper l0 strikes the stripper plate 32 causing it to slide from the slot 28 as the pad wheel 23 is rotated.
  • the diapers are thereby placed in essentially vertical orientation on the stripper plate 32 (FIG. 3).
  • the previously deposited diaper or diapers 10 of a given stack 31 are moved slightly forward by the trailing edges 33 (FIG. 3) of the pad wheel 23.
  • Means are provided to hold the diapers in their upright position and prevent twisting thereof as they are removed from the pad wheel 23 to form a stack 31 on the stripper plate 32.
  • Mounted along opposite sides of the stripper plate 32 in substantially vertical orientation are guide plates 34 and 35 (FIG. 7).
  • a plurality of flexible fingers 36 (FIGS. 7 and 8) which may be formed of rubber or like material are mounted such that one row is above and another row below the guide plates 34 and 35.

  • the flexible fingers 36 on opposite sides of the tunnel 37 are spaced apart such that they engage the side edges of the diapers forming-the stacks 31. This maintains the diapers upright during their insertion in the tunnel 37 regardless of whether the diaper supply is continuous or interrupted.
  • Means are provided for conveying and moving the stack onto a support plate.
  • means for moving the stacks 31 is supported by the frame 18 and includes a chain 38 running over the several illustrated sprockets (FIG. 3).

  • the chain 38 is intermittently moved when a completed stack 31 has been formed to move the stack from the stacking station adjacent the pad wheel 23 by sliding it through the tunnel 37 for the purpose of delivering the completed stack to a second station at a pocket of the stack wheel 45.
  • the individual pusher elements 39 are relatively narrow permitting their movement between the spaced elements 23-23 forming the pad wheel.
  • a central slot 46 is formed in the stripper plate 32 to permit movement of the pusher elements 39 to the stack wheel 45 and beyond.
  • the stack wheel 45 is mounted for intermittent rotation on the frame 18 and contains a plurality of pockets 47, each being designed to receive and retain a stack 31 of diapers 10.

  • the arm 42 is pivoted into its extended position after movement of the chain 40 such that the pad 44 on the arm 42 will be stopped in position to contact the foremost diaper in the completed stack 31.
  • the arm 42 is pivoted to its retracted or inactive position after the stack 31 is delivered to the pocket 47.
  • the chain 40 moves intermittently in unison with the chain 38.
  • the movement of the chains 38 and 40 is timed so that a completed stack 31 is formed between a pushing element 39 and a stack controller arm 42.
  • the chains 38 and 40 are put in motion so that a cohesive stack 31 is moved and delivered from the stacking station to a second station at the pocket 47 without any of the diapers 10 becoming dislodged or otherwise disoriented in the stack.
  • a pair of spring loaded side members 48 and 49 are provided at opposite sides of the pocket 47 of the stack wheel 45. These side members 48 and 49 are provided to prevent lateral movement of the stack and thereby retain it in the pocket 47.
  • a plurality of flexible fingers 50 In the inlet portion of the pocket 47 are mounted a plurality of flexible fingers 50 provided to permit entrance of the stack 31 into the pocket 47 with relative ease. The fingers 50 tend to preclude reverse travel and retain the stack in the pocket.

  • the pad wheel 23 is rotated continuously whereas the pushing elements 39, the stack controller arms 42 and the stack wheel 45 are moved and/or rotated intermittently inasmuch as their movement is dependent upon the formation of a completed stack 31 before they can move the stack and be in position to receive the next succeeding stack.
  • the pushing elements 39, the stack controller arms 42 and the stack wheel 45 are driven by the stack cycle shaft 51 which receives its power input from the pad cycle shaft 24. Whereas the pad cycle shaft 24 makes one revolution per diaper, the stack cycle shaft 24 makes one revolution per stack.
  • the drive from the pad cycle shaft 24 to the stack cycle shaft 51 includes a differential drive element 52 that has two inputs. The first is a direct input to the shaft 53 by means of the chain 54 driven by the pad cycle shaft 24. The second input to the differential drive 52 is from the one revolution clutch 55.
  • the output from thedifferential drive 52 is directly coupled to the stack cycle shaft 51 .by means of the gear box 56. Ordinarily the pad cycle shaft 24 will thereby directly drive the stack cycle shaft 51 at the proper reduction through the intermediary of the differential drive 52.
  • the one revolution clutch 55 is energized by a suitable control (not shown) which is designed for detecting any missing diapers.
  • the one'revolution clutch 55 then exactly cancels the input from the shaft 53 for one revolution and this then precludes movement of the stack in formation for an additional revolution of the pad cycle shaft 24 so that the predetermined number of diapers is deposited in the stack 21.
  • the differential drive 52 is used to provide a variable control whereby each stack formed on the stripper plate 32 will have the same number of diapers therein (usually either 12 or depending on diaper size).

  • the chain 40 for moving the stack controller arms 42 is driven intermittently from the stack cycle shaft 51 so that it moves synchronously with the chain 38.
  • the drive for the chain 40 is not illustrated because it is identical to that used for the chain 38. That is, it includes a conventional chain and sprocket drive mechanism from the shaft 51 to a conventional indexing mechanism (not shown), the output of which is transmitted to a gear box (not shown). The output from the latter gear box is used to intermittently drive the chain 40 through the medium of another conventional chain and sprocket drive.
