Definitions

  • This invention relates to improvements in sheet delivery mechanism, and has reference particularly to means for reducing the rate of travel of the sheets after they are released by the conveyor grippers preparatory to being deposited upon the top of the delivery pile.
  • One such mechanism comprises a series of rotating suction wheels driven by a mechanical connection with the conveyor at wheel surface speed substantially less than the linear speed of the sheets being drawn over the suction wheels by the conveyor. These wheel have the advantage that they are in continuous rotation, and therefore function to drive the sheet forward at somewhat reduced speed after the sheet has been largely decelerated following release by the grippers.
  • Such devices are subject to the serious disadvantage however that their speed of rotation, and therefore their retarding action upon the sheet, changes when the speed of operation of the machine and its conveyor are changed. That is, as the speed of the conveyor is increased the speed of the suction proportionately.
  • the deficiencies of previous devices are overcome by providing rotating suction wheels for slowing down the sheets and thereafter advancing them onto the pile, which wheels are driven at a selected speed which is independent of conveyor speed and which preferably may be selectively varied by the operator to meet various conditions of conveyor speed and quality of sheets.
  • One of the objects of the invention therefore is the provision of means for quiet, uniform deposit of sheets dropped from a rapidly moving conveyor.
  • Another object is the provision of means of the character stated which may be adjusted to compensate for different grades of stock and different printing press speeds.
  • Still another object is the provision of means for decelerating sheets released by a conveyor, which means shall have motion not directly proportional to the speed of the conveyor, and which shall be adjustable to vary the rate of deceleration for a given conveyor speed.
  • Fig. 1 is a side elevational view of a delivery mechanism embodying the invention.
  • Fig. 2 is an end elevational view partly in section along the line 2-4 of Fig. 1.
  • Fig. 3 is a detail view, partly in section and on a larger scale, of the jogger and suction wheel mechanism taken along the line 3-3 of Fig. 2.
  • Fig. 4 is a fragmental detail view, partly in section. of one of the suction wheels.

Sheets are conveyed from the sheet handling machine, such as a printing press, not shown, by an endless conveyor which comprises parallel chains and I5 joined at intervals by gripper bars [1 in the usual manner.
  • the chain l5 runs between tracks [8 on one side of the machine, and the chain I6 runs between tracks I9 on the other side of the machine, which tracks are secured to brackets 23, 2
  • the conveyor follows an upward path indicated at 22 a it leaves the printing press, the chains passing around idler sprockets 23 rotatably supported on tie rod l3, and then traveling along a horizontal path to the idler sprockets 24; after which the chains return to the printing press along a path not illustrated in the drawings.

  • air under pressure is directed through pipe 48 and flexible hose connection 43 from a source of compressed air, not shown.
  • Another chamber 50 in bracket 42 is connected by pipe 5
  • Chamber 50 is connected by a short pipe 53 and elbow 54 to a hollow pipe 55 which is rigidly supported in the brackets 35, 39 and is closed at one end by a plug 56.
  • brackets 35 and 39 are also joined rigidly by an angle bar 51 which is securedto studs 58 fixed in the brackets 35 and 33.
  • brackets together with the pipe 55 and angle bar 51 form a rigid frame structure adj ustably secured at its ends to bars 32 and 33, and movable back and forth with r the latter bars.
  • Each of the end jogger plates 53 is carried by means of a pair of gibs 35 upon an upright extension 5! of an arm 62' which is clamped to pipe 55 as illustrated in Fig. 6, which arm is provided with an extension 63 carrying an adjusting screw 64 adapted to bear against angle bar 51.
  • the arrangement is such as to permit accurate vertical alignment of the plates 59 as well as to permit removal or lateral adjustment of the plates.
  • a series of. flexible tapes 65 Secured to the angle bar 5'? is a series of. flexible tapes 65 which extend over idler wheels 66 rotatably mounted on tie rod i3 and downwardly along a line approximately parallel to the path of the conveyor. Weights, not shown, are provided on the ends of the tapes to keep them taut as the angle bar 51 moves back and forth during operation of the machine.

  • the chamber ll. isconnected by flexible'tubing T5 to suction pipe 55, thereby permitting limited adjustment of the wheel'transversely of the machine.

  • rotatably mounted in abracket 35 which sur rounds the tie rod l3 and is secured by bolts 86 to the inside surface of frame member I I.
  • Shaft 84 at its other end carries a sprocket 81 which is driven by a chain 88 traveling around a sprocket 89 secured to the output shaft of a variable speed transmission device 90 mounted by bolts 91 on a ledge formed in frame II.
  • the input shaft 92 of the variable speed transmission device carries a spiral gear 92' which is driven by a further spiral gear 93 keyed to a shaft 94 supported in bracket 95 at one end and in frame member l2 at the other end.
  • Shaft 94 is driven at constant speed by an electric motor 95 through belt 91 and pulleys Fill and 99 keyed to the motor shaft and to shaft e4 respectively.
  • the variable speed transmission device 90 may be of any suitable or desired type. In the illustrated case it has an adjusting crank I which may be manually turned in order to change the speed ratio of the input and output shafts.
  • the speed of the motor 96, the various driving connections and the characteristics of the transmission are so chosen that the speed of the suction Wheels 66 may be varied within the limits required by the speed of the machine and the character of sheets to be delivered It has been found that for a conveyor handling ordinary weights of paper at a maximum speed of about 400 to 500 feet per minute, good results are obtained where the wheel surface speed is adjustable between zero and about 100 feet per minute.
  • the oscillations of bars 32 and 33 are so timed in relation to the travel of the grippers l I that the jogger plates 59 and their associated suctien wheels 66 are traveling bodily toward the pile 25 at a point about midway of their motion at the time the grippers I1 let go of the forward edge of the sheet.
  • the tail edge portion of the sheet is still engaged by the suction wheels 56, with the result that the sheet is quickly decelerated to substantially the speed of the suction wheels.
  • the continued ro- ,at.ion of the suction wheels permits or promotes further forward motion of the sheet until its rear edge passes the active suction slots at the top of the wheels.
  • the wheels release the sheet.
  • the wheels and the plates.59 have reached their forwardmost position they withdraw from the pile, permitting the tail portion of the sheet to drop onto the pile in approximately its final position, ready to be jogged into precise alignment by jogger plates 59 upon their next movement toward the pile.
  • Any desired number of wheels and jogger plates may be employed. Also, suitable adjusting valves will ordinarily be provided to control the extent of air pressure and suction. While I prefer to maintain suction in wheels 66 and pressure in pipe 44 continuously, timing valves may be provided for the purpose of cutting off the suction and pressure during the time the gap between successive sheets on the conveyor is passing the wheels.
