  • FIG. J9 SYSTEM FOR AUTOMATICALLY TYING BUNDLES Filed Oct. 6, 1960 l2 Sheets-Sheet 5 FIG. J9
  • Incoming mail in a post otiice is generally sorted as to destination, and all letters having the same destination are assembled into a bundle which is then tied with a string to facilitate subsequent handling thereof.
  • a bundle of mail may be approximately 51/2 inches wide, 111/2 inches long and 41/2 inches thick, these dimensions being the maximum -dimensions for the width and length of the envelopes handled and for the thickness of the bundle into which the envelopes are assembled.
  • Each such bundle is tied in a tying machine which may be of the type described in B. H. Bunn Patent No. 2,898,847 dated August 11, 1958.
  • Such machines are adapted to tie a lbundle in one direction with a double wrap', the operator then turning the bundle through 90 to effect a tying of the bundle in a transverse direction.
  • Such machines may also be equipped with a trip mechanism which initiates the operation of the tying mechanism when a -bundle of mail is placed over the trip mechanism and depressed to operate the trip mechanism.
  • the machines as heretofore constructed required that an operator be assigned to each machine, each such .operator bringing a bundle of mail to be tied to the machine and holding it on the machine While the bundle was tied in one direction. He was then required to turn the tied bundle through 90, hold the turned bundle on the machine to effect a cross tie thereof, and then remove the cross tied bundle from the machine.
  • An object of this invention is the provision of a conveyorized system -for delivering sorted mail in bundles to a bundle-tying station where the bundle is automatically transferred from the conveyor to a tying machine, with means for automatically ejecting a tied bundle fromythe machine.
  • Another object of this invention is the provision of a transfer mechanism for transferring a bundle of loose, untied mail from a conveyor to a tying machine without interrupting the continuous operation of the conveyor.
  • Yet another object of this invention is the provision of a pair of tyingmachines each adapted to tie a bundle of loose mail in a direction transverse to the other, with means for automatically transferring the ⁇ bundle from one machine to the other, thereby effecting an assembly line operation of the tying machines.
  • this invention has within its purview the provision of a control mechanism for initiating the operation of a pair of bundle-tying machines, said control mechanism automatically rendering a machine inoperative unless a bundle to be tied is placed thereon.
  • this invention provides a control mechanism for operating transfer mechanisms and bundle-tying machines in proper sequence to effect a tie in two directions on said bundle, with means for automatically cutting out certain of the operations when no bundle is to be tied.
  • Yet another specific object of this invention is the provision of a conveyorized system of tying bundles of mail, said system incorporating a conveyor unit for bringing mail sorted at one or more locations to a common point, picking oit the sorted bundle from the moving conveyor and transferring these one at a time to a first tying machine ⁇ for tying the bundles in one direction, transferring the bundles to a second tying machine for tying them in a direction transverse to the first tie, and finally ejecting the tied bundle from the second machine.

  • the transfer mechanism 4l is required to pick off a bundle from the vertical section 4S of the conveyor while the bundle is moving downwardly, and transfer such bundle to the first tying machine 42.
  • Means hereinafter to be described are therefore provided for imparting a vertical movement to the first transfer mechanism 4l in synchronism with the vertical movement of the bundle to be removed from the conveyor while the removal thereof takes place, a horizontal movement into the bucket to .grasp the bundle of envelopes carried therein, a reverse movement in a horizontal direction to withdraw the bundle from the bucket, ay swinging movement in a horizontal plane to bring the bundle to a desired location on the first tying machine, and a final withdrawing movement and swinging movement to bring the transfer mechanism into .position for grasping a second bundle.
  • the first transfer mechanism is designed to run continuously with the conveyor 40 and to go through its cycle of movements whether or not there is a bundle of mail in each bucket. It is not desirable, however, to have the first tying machine 42 running continuously and hence means are provided, ⁇
  • the second transfer mechanism 43 is triggered to operate from the operation of first tying machine 42 so that if the first tying mechanism or machine does not operate, the second transferring mechanism likewise will not operate.
  • the operation of the first tying machine will cause an operation of the transfer mechanism 43, which then pushes the tied bundle to the table of the second tying machine 44.
  • There a mechanism will sense the presence of a bundle and will cause the bundle to be tied in a direction crosswise of the first tie.
  • the sensing mechanism for the second tying machine will be triggered by the operation of the first tying machine so that if there is no bundle in the first tying machine, the sensing mechanism will not operate and the second machine, as well as the third transfer mechanism, will be inoperative.
  • the sensing mechanism for the second tying machine 44 will operate but will sense the absence of a bundle and hence will prevent the automatic operation of the second tying machine.
  • a control for the third transfer mechanism will be set in operation and will cause the third transfer mechanism to remove the tied bundle from the second tying machine and into a hopper or possibly to another conveyor (not shown).
  • the transfer mechanisms and certain bundle holddown mechanisms associated with the two tying machines are pov/ered by known readily available air cylinders controlled by ,electromagnetically operated valves which in turn are energized by micro-switches disposed in the path of movement of a member performing an antecedent function.
  • a first group of micro-switches controls certain movements of the first transfer mechanism and is operated by an element or elements movable with the conveyor.
  • a second group of microswitches, operated by the movement of elements of theV first transfer mechanism controls other movements of the first transfer mechanism and initiates the movement of the hold-down mechanism of the first tying machine.

  • Said front wall 64 is relieved or notched at its upper end as at 65 to expose the upper ends of the envelopes in the bucket to the pick-up elements of the rst transfer mechanism 41.
  • the front wall 64 slopes backward- 1y from the perpendicular to the bottom 62 as viewed in FIG. 26. The purpose of this slope is to make certain that as the buckets move down the vertical section of the conveyor, the envelopes will tend to slide toward the bottom 62 rather than in the opposite direction and fall out of the bucket. It is contemplated that as a bundle of envelopes is placed into a bucket, the operator will push the bundle against side wall 63 to level the bundle somewhat at that end and that he will allow the individual envelopes in the bundle to fall against the bottom 62 of the bucket and thus level olf the edges of the envelopes adjacent thereto.

  • Cylinder 86 provides the pressure for contacting a bundle of mail and hence, to avoid exerting destructive pressure upon the mail, is designed to operate at a lesser pressure than the remaining cylinders. Accordingly, a branch line 232 is connected to a pressure reducer and regulator 233, from which the air passes through a pipe 234 to cylinder 86.
  • Cylinders 118, 98, S6, 115, 134 and 15.3 are of the type shown in FIG. 33 and have a separate solenoid for controlling movement of the associated piston in each direction; that is, one solenoid controls movement of the piston rod associated with the enclosed piston out of the cylinder, and the other solenoid controls the return movement of the piston rod into the cylinder.

  • This cylinder rotates the pick-E head with the clamped bundle in it through 90 to the first tying machine 42. This is rshown in FIGS. 9 and 10.
  • Switch 211 being in parallel wi-th switch 188, performs the identical function as switch 18S and causes the cylinder 98 to extend its rod and the associated head toward the tying machine while the cylinder 115 is swinging the pick-off head toward the ltying machine as stated above.
  • Switch 212 controls the hold-down mechanism operated by cylinder 1134. It is desirable, of course, that the bundle be properly located on the tying machine before it is clamped by the hold-down mechanism 129, and hence switch 211 is operated in yadvance of switch 212. It is also essential that the Ibundle be in place before the tying operation commences. Since the pressure of the holddown cylinder 134 is relied upon to operate the trip lever 127, this provides additional reason for causing switch 211 to be operated before switch 212.
  • Switch 216 controls the raising of the clamping cylinder from the bundle and switch 217 duplicates the function ⁇ of switch 190 and therefore serves to wi-thdraw the head linearly from the bundle.
  • switch 187 the next -pin 186 on sprocket 71 has contacted the operative end 192 of switch 187 which causes the piston rod and cylinder 11S to be extended to raise the head at the same time that the cylinder is rotating the head back to a position confronting the vertical section 48 of the conveyor. This brings the pick-off head back to its starting position.
  • the pick-off head has described a complete cycle of operation, the bundle is only in its rst tying position on the rst tying machine. It may be recalled that when the cylinder 134 Iwas operated to lower the hold-down mechanism 129 upon the bundle, and the bundle thereupon operated the ltrip mechanism for the machine, the tying operation for thernachine was commenced which involved the rotation of the mutilated gear 197 of the first tying machine to cause the sequential operation of the switches to be contacted by the pin 291, cam 202 and pin 203- on said mutilated gear.
