Definitions

  • the diverting device comprises an upper and a lower belt conveyor supported by a carriage movable along an inclined path relative to the main path of the stream of signatures, the lower end of the lower conveyor forming a freely projecting end which is adapted to be introduced into said gap between two consecutive signatures.
  • the present invention relates to a method and a conveying path of the kind set forth in the preamble to the claims 1 and 2 following hereafter.
  • conveying paths for a stream of signatures or newspapers overlapping each other there are known devices which at will can cause the diversion of a stream of signatures to a branch path.
  • the known devices are not suitable for plucking out a solitary signature for inspection of the quality of the print on the signature.
  • the aim of the present invention is to accomplish a device which makes this possible and can alternatively also be used to divert a plurality of signatures if so requires, e.g., to separate a number of signatures which are to go to waste because of poor quality.
  • the branch path has thus a displaceable carrier provided with an upper and a lower belt conveyor and which can be quickly shifted to a gripping position where the spine of a signature is immediately gripped between the conveyors, whereafter the carrier is snatched back, taking with it only one signature. If the carrier is permitted to remain in the plucking position, signatures will be diverted as long as the carrier remains in this position.
  • FIG. 1 is a schematic longitudinal section through the main conveying path and a branch path according to the invention.
  • FIG. 2 is an elevation taken from in front of the branch path.
  • the main path and the branch path consist in a known manner of driven belt conveyors with a number of belts, ribbons, chains, wires or other similar means side by side passing over a number of jockey pulleys, rollers or the like.
  • a conveyor is composed of a number of spaced belts or the like and rollers, reference will be made merely to one of the belts and one of the rollers seen in FIG. 1.
  • the main path has an approach portion 10 extending somewhat slantingly upwards to an upper jockey pulley 12, round it and backwards to a lower jockey pulley 14, round this and thereafter forming an essentially horizontal exit portion 17.
  • a crest 16 is formed at the pulleys 14, 12 so that when the signatures pass over the upperjockey pulley 12, they will cease to lie flat against each other because the signatures bend one at a time towards the exit portion 17 of the path.
  • a widened pocket 18 is hereby obtained between the spine edge 20a of the uppermost signature 20 and the downwardly bent preceding signature.
  • the pulley 14 may be omitted so that the crest portion 16 of the main path will be obtained merely by the pulley 12.
  • the pulley 12 and/or 14 may be formed by a shaft having the same diameter as the pulley 12 and/or 14.
  • the jockey pulleys or shafts 12, 14 of the main path are supported by shafts mounted in parts 22 supported by the frame of the machine.
  • a carrier 24 having two side plates 26 joined together by transverse struts, one
  • the side plates carry a number of shafts 30, 32, 34 provided with jockey pulleys 38, 40, 44 for a lower belt conveyor 46, the belt of which further passes over a tensioning pulley 48 on a shaft 50 which is mounted on adjustable arms 50a journalled on a frame part 22a.
  • the carrier also supports an upper belt conveyor 52 with shafts 54, 56, 58 provided with jockey pulleys 62, 64, 66.
  • the carrier 24 is displaceably mounted for displacement in a sloping plane between the lower end position, shown in solid line fashion, to the upper end position shown with dotted lines in FIG. 1.
  • This displacement is accomplished by two cylinders 70 supporting the carrier 24 and being displaceable on two stationary piston rods 72, each of which have a fixed piston 70a which in a manner known per se divides the cylinder into two chambers.
  • pressurized air is admitted through inlet 70b, the cylinders will be moved upwardly to move the carrier 24 rapidly to its upper end position.
  • air is led to inlet 700 the carrier will be moved rapidly to its lower end position.
  • the upper part 74 of the lower conveyor 46 extends from the lower jockey pulley 38 or a corresponding shaft to the upper jockey pulley 42, round it and down to the tensioning pulley 48. From here the belt extends backwards in a loop 76, 78 round the intermediate jockey pulley 44 and forward to the lower jockey pulley 38.
  • Pulley 42 is mounted on driven shaft 36 journalled in the two side plates 22 of the machine frame.
  • the upper conveyor has a lower part 80 extending from the lower jockey pulley 66 to the upper jockey pulley 64 and lying adjacent to the upper part 74 of the lower conveyor. From the upper jockey pulley 64 the belt extends via tensioning pulley 68 to the extra jockey pulley 62 lying in front of the lower jockey pulley 66. Between the two pulleys the belt forms an end portion 82 which is shown as being horizontally but may be inclined.
  • the upper part 74 of the lower conveyor has a free end portion 84 between the jockey pulleys 66 and 38, this together with the end portion 82 of conveyor 52 forms a pocket for receiving the signature 20 forming the upper part of pocket 18.
  • the conveyors are driven by having a driving motor coupled to the pulley 42 for driving the lower conveyor. From this conveyor, drive is transmitted to the upper conveyor between the shafts 34 and 56 with their respective chain wheels 86, 88 around which are placed a chain 90.
  • the carrier 24 When a single signature is to be plucked from the stream of signatures, the carrier 24 is moved by cylinders 70 quickly from its upper end (dotted) position to its position shown with full lines in FIG. 1, where the lower jockey pulley 38 enters the widened pocket 18.
  • the signature 20 lying uppermost and beginning to move over the jockey pulley 12 will be thrown forward with its spine 20a contacting the forward end portion 84 of the belt part 74.
  • the signature 20 is thereby led up into engagement between the lower pulley 66 and the upper part 74 and is drawn upwards between the lower part 80 and the upper part 74.
  • the spine edge portion of signature 20 When this has taken place, the spine edge portion of signature 20 will be at a position between the ends of the lower part 80, that is gripped by the upper and lower conveyors.
  • the carrier 24 is now quickly withdrawn to its upper end position, simultaneously withdrawing a single signature from the stream. If the upward speed of the carrier upon displacement is approximately equal to the driving speed of the belts 74, 80, the belts will stand essentially still in comparison to the carrier during its movement, which is due to the relative movement obtained at the pulley 44 by reason of the pulleys 48 and 42 hav ing a fixed position. This means that the carrier may arrive at its upper end position before the signature has reached pulley 42. The signature is thereafter led away to an inspection station on paths not shown.
  • this device brings with it a simple means of transferring drive to both the upper and lower conveyors from a stationary driving motor through the shaft 36 to conveyor 46 and via chain 90 to conveyor 52.
  • the carrier 24 is allowed to remain in its lower end or gripping position.
  • Conveying path with a main path and a branch path optionally engageable and alignable with the main path for conveying a stream of signatures, weekly journals, brochures or the like, which overlap each other having their spines facing forward in the conveying di' rection, the main path having a crest so arranged to accomplish a separation of the signatures in the area at the crest so that a shunting device, movable between two end positions, is introducible in a gap formed between two adjacent signatures, when the foremost of these bends over the crest, characterized in that the branch path is defined by a carrier which is displaceable in a sloping plane between an upper and a lower end position, said carrier supporting an upper and a lower endless driven belt conveyor with a number of endless belts, running over jockey pulleys, forming the conveying elements of the conveyors, the upper conveying element having a portion of the lower conveyor extending between a first lower and second upper jockey pulley, the lower conveying element having a portion of the
  • Conveying path according to claim 2 characterized in that'the upper conveyor has a fifth jockey pulley at its lower end, said fifth jockey pulley together with the third jockey pulley of the upper conveyor defining an end portion forming an acute triangle with the free end portion of the lower conveyor to define a tapered entry for a signature, and coacting to guide at least one signature therebetween, when the carrier is lowered to its lower end position.
  • a shunting device for deflecting signatures away from the main path and along a branch path, said device comprising:
  • said first pulley being positioned closer to said gap than said third pulley
