Definitions

  • Lackey ABSTRACT An automatic cloth roll loading apparatus including an inclined roll supporting platform, a stationary barrier cooperating with the lower end portion of the platform, and means for raising the platform to a dumping or discharging position above the barrier and for lowering the platform to a roll storage position in cooperation with the barrier.
  • a further feature of the apparatus is a cloth roll storage truck having at least one roll supporting cradle adjacent the upper end of the platform, and pivotal fingers projecting from the rear of the platform adapted to interdigitate with the eradle in order to lifi and remove one roll at a time from the truck to the platform on each upward movement of the platform.
  • This invention relates to a roll loading apparatus, and more particularly to an apparatus adapted to automatically store a plurality of rolls and to feed or discharge one roll at a time to a discharge station, such as a cloth spreading machine.
  • the cloth spreading machine In the art of spreading cloth from a roll, the cloth spreading machine is provided with a support for one roll of cloth in operative position for spreadingv After the spreading operation has exhausted each roll, the machine must be stopped, and another roll of cloth is mounted upon the roll support. The cloth from the roll is then threaded through the various guide rollers and bars and through the spreading elements, such as the fold or tuck blades.
  • the rolls are manipulated by hand, but where excessively large rolls, or rolls of heavy web material, are used, hoisting machinery must be employed. Regardless of the size or weight of the roll, or the various operations for mounting the rolls on the machine, considerable time is lost in the loading operation.
  • This apparatus contemplates a loading apparatus which is also provided with a mechanism for storing one or more cloth rolls upon an elevator platform which will hold the roll or rolls until needed, ed, then, upon signal, elevate and discharge the roll upon the cloth spreading machine.
  • the apparatus further contemplates a loading assembly including a rack having a large capacity for storage ofa plurality of cloth rolls, and for automatically feeding the rolls from the rack to the loading apparatus so that there will be an ample supply ofcloth rolls at all times.
  • the apparatus is also rendered portable so that it may be moved to different locations for supplying rolls to more than one cloth spreading machine.
  • FIG. I is a side elevation of the loading apparatus, with parts broken away, including a loading unit and a roll storage truck, and disclosing a portion ofa cloth spreading machine, in phantom;
  • FIG. 2 is a top plan view, with parts broken away, of the assembly disclosed in FIG. 1;
  • FIG. 3 is a front elevation of the loading apparatus, with parts broken away;
  • FIG. 4 is an enlarged section taken along the line 4-4 of FIG. 3, showing the storage truck fragmentarily;
  • FIG. 5 is a fragmentary section taken along the line 5-5 of FIG. 4;
  • FIG. 6 is a fragmentary side elevation ofthe upper portions of the assembly showing the feeding and loading operations in sequence.
  • FIG. 7 is a fragmentary side elevation similar to FIG. 6, showing additional operational sequences.
  • FIG. 1 discloses a preferred form of loading apparatus, including a loading unit or loader l0 and a storage truck 11, for loading cloth rolls upon a cloth spreading machine 12.

  • the upper reversing switch 56 is so located that it is actuated by the side frame 28 when the inclined platform surface 26 is approximately flush with the free top ends of the barrier posts 50, in which position, the roll, such as cloth roll 52, is permitted to roll over the ends of the posts and be discharged upon any desired location or discharge station, such as the auxiliary platform I7 ofthc cloth spreader 12.
  • the stop switch 55 is located slightly below the upper reversing switch 56 to permit the platform member 25 to stop at the positions disclosed in FIGS. 1 and 4 in a storage position preparatory to discharge.
  • the lower reversing switch 54 may be located at any posi tion in which it is desired to reverse the motion ofthe platform member 25 from down to up.
  • the safety stop switch 57 is optional, and is merely provided so that if the platform member 25 continues upward without actuating switches 55 or 56, so that the guide holes 51 are above the barrier posts 50, the movement of the platform member 25 will be stopped. The platform member 25 can then be manually restored to its normal operating position within the limits of the upper and lower switches 56 and 54.

  • each shelf 62 and 63 will support several cloth rolls, and after a roll is removed from the corresponding cradle arms 65 or 67, the next succeeding cloth roll will gravitate into the same position upon the cradle arms 65 and 67, respectively.
  • each finger 71 Pivotally mounted upon a rod or shaft 70, extending across and beneath the upper end of the platform surface 26 are a plurality of roll engaging fingers 71.
  • the front end of each finger 71 is provided with a stop pin 72 to limit the downward swinging movement of the finger 71 to substantially the same inclined direction as the inclination of the platform surface 26, as disclosed in solid lines in FIGS. 1, 4, 6 and 7.
  • the fingers 71 may swing to raised positions such as indicated in phantom in FIG. 6.
  • At least one of the fingers 71 is provided with a switch arm 73 adapted to engage and actuate a reversing limit switch 74 mounted on the bottom of the platform surface 26, as best disclosed in FIGS. 4, 6 and 7.
