Definitions

  • the present invention concerns a method and an arrangement for the group-dividing of folded printed matter, primarily newspapers, which are conveyed in a continuous flow in overlapping scale formation on a conveyor belt. It is normal that freshly-printed newspapers leave the rotary printing press in a flow, with the fold-edge foremost in the direction of transport and resting on top of the preceding newspaper, and it is well-known that it can hereby be desirable to bring about a certain dividing of the continuous flow with the view to being able with suitable means to separate finished stacks of newspapers from the flow for further handling. For this purpose, it is necessary for a certain pause or "hole" to be created in the flow of newspapers, so that the gripping means used for collection can begin the collection of such a stack in a well-defined manner.
  • the object of the invention is to provide a separation arrangement which in a gentle manner can create a separation of or in the item flow, so that smudging and blurring of the printing ink or other damage to the items can be avoided.
  • this object can be achieved by carrying out a detection near the dividing point of the passage of the front edges of the items arriving in a flow, and that on the basis hereof and at the desired time to quickly bring about an activation of an overlying sheet tongue for lowering/displacement towards the flow of items in such a manner that this sheet tongue will in a well-defined manner wedge itself under the folded, upper front edge of a given item and the top of the item lying underneath, so that the upper item can be held back by the contact of the upper folded edge of this item against an upright root part of the sheet tongue, without the sliding forwards of the underlying item causing any smudging, the reason being that the inserted sheet tongue will hold the surfaces of these items separated from each other.
  • the said detection of the passing of the front edge can also be used for the controlling of a counter which can count the passage of a desired number of items for feeding together in separate bundles.
  • a counter which can count the passage of a desired number of items for feeding together in separate bundles.
  • a conveyor belt 2 which feeds a flow of scale-oriented items 4 from a rotary press forward to a fallout area in the form of a magazine shaft 6, which at the bottom has an outgoing conveyor belt 8 for a stack of items 10 built up on the belt.
  • this magazine there can be established an intermediate bottom by sideways insertion of outer bottom plates 12.
  • a sensor 14 is provided above the belt 2 for detecting the passage of the upper front edges 16 of the items 4, whereby with the use of an associated counter it can be determined how many items shall be fed forward or the formation of a full stack 10. When this number has been reached, the intermediate bottom plates 12 are inserted to the position shown in fig. 2, i.e.
  • the feeding speed is quite high, and in order to achieve a well-defined separation between the items for the building-up of the stacks with a specific number of items, it is desirable to establish a certain pause in or of the flow of these items to provide time for the insertion of the intermediate bottom plates 12 at a well-defined time.
  • such a pause is established by providing a separation mechanism 18 over the conveyor belt 2, this mechanism 18 being suspended in a pivotal parallelogram control system 20 with a guide plate 22 and a roller 24, which is a lower changeover roller for an inclined, smooth belt 25 extending forwards and downwards, and which during operation rests down against the top of the item layer 4.
  • a compressed-air cylinder 26 Fastened at the front end of the guide plate 22 there is a compressed-air cylinder 26, the piston of which supports a lower, protruding sheet tongue 30, to which there is fastened an upright plate part 32, from which front edge the sheet tongue 30 has a short, forwardly-extending end part 34 configured with a rounded end shape and directed tangentially forward towards the underside of the roller 24.
  • the air cylinders 26 are activated for a very quick forwards displacement of the sheet tongues 30, i.e. rearwards in relation the transport direction of the items 4. Because of the slightly inclined position of the cylinders 26 as shown, the outer ends 34 of the sheet tongues will hereby be displaced from a passive position just behind and slightly raised above the contact line of the rollers 24 against the top of the items 4, to an active position just in front and only slightly below this line, whereby the ends of the sheet tongues are brought into light contact with the top of that item which is currently being fed down under the rollers 24.
  • This displacement of the tongue ends can typically be activated precisely at the moment at which the item feeding phase is as shown in fig. 1, i.e. when the front edge 16 of the next item 4 is still lying at a certain distance from the rollers 24. It can be envisaged that the feeding of the items 4 can typically take place with a capacity in the order of 10-20 items per second, and that the activation must therefore be effected quickly in order for the sheet tongues to be able to reach forward to their active position before the arrival of the front edge 16 of the next item 4.
  • a withdrawal of the sheet tongues can be initiated as soon as - or immediately before - the intermediate bottom parts 12 are inserted for closing above the stack of items 10 which has been formed in the meantime (fig. 2).
  • the items which have hitherto been held back will be released, so that these can now be fed further on the belt 2 and hereby be pressed in under the rollers 24 for the raising of these rollers, and herewith also for the raising of the now passive sheet tongues, after which the situation will again quickly become the same as shown in fig. 1.
  • the building up will begin of a new stack of items on the intermediate bottom 12, which is opened as soon as the preceding stack has been led away on the belt 8.
  • the changeover in the stack magazine can possibly be effected so quickly that the situation shown in fig. 2 will almost never arise, in that it is possible to work with such a brief activation of the sheet tongues that only some of the underlying items 4 will manage to be fed further on the belt 2 before the sheet tongues are de-activated.
