Definitions

• the invention lies in the field of further processing of printed products and relates to a method and a device according to the preambles of the corresponding independent claims.
• the method and the device serve to form and strapping lying stacks (bars) of printed products.
• intermediate and partial products such as individual sections of newspapers or magazines that are printed before other sections, signatures from which books are later to be made, or single sheets, brochures, smaller brochures, partial sheets etc. that later become newspapers or Magazines are added as supplements or collected parts, temporarily stored between their manufacture and further processing, and are therefore transported within the company and, if necessary, from one company to another company.
• intermediate products in horizontal stacks, so-called bars, and to store and transport them, for example, stacked on pallets.
• the stacks mentioned usually have a length (perpendicular to the surface of the printed products) which is significantly greater than the edge lengths of the printed products. So there are stacks that are not stable without aids, not even vertically.
• the length of the stacks is matched, for example, to the dimensions of the pallets on which they are stacked and with which they are transported and stored, that is to say the stacks are usually 120 or 150 cm long and comprise, for example, 200 to 300 printed products.
• the stacks are stacked one on top of the other on the pallets and thus form storage units that can be manipulated easily and in a space-saving manner with generally common storage vehicles.
• the end faces of the stacks are usually stabilized with end plates, for example wooden boards, which are matched to the format of the stacked products, and the stacks are pressed together by strapping, which consists, for example, of a plastic band.
• strapping which consists, for example, of a plastic band.
• the strapping runs over the longer edges of rectangular printed products, depending on the product format, once in the middle or twice, with the two straps dividing the end faces into three parts of approximately the same size.
• the lying stacks are usually produced by lining up products standing on one edge, by stabilizing the products lined up on both sides by means of end plates and by subsequent pressing and strapping.
• the printed products to be processed into bars are thus supplied, for example, in a stream of overlapping conveyed printed products (shingled stream) from above against a horizontal conveying base or slightly falling away from the feed and placed thereon.
• On the conveyor base they are conveyed one behind the other, standing on one of their edges (usually folded edge or back edge) and mutually supported or pushed away from the feed in this position.
• a lying stack that is essentially continuously growing in a stacking direction (conveying direction of the conveying base) is created on the conveyor base.
• This continuously growing stack turns into discrete stacks of a given length or number of products separated, provided with end plates on both sides, pressed and strapped.
• the end plates are usually positioned on the conveyor base in corresponding gaps in the growing stack while the stack is being conveyed.
• the separated stacks provided with end plates are accelerated in the stacking direction and conveyed into a strapping position, where they can also be moved transversely to the stacking direction. After the strapping, the stacks are conveyed away.
• a device for forming and strapping lying stacks of printed products is known, for example, from the publication US-4772003 (Nobuta et al.).
• a stream of shingles is fed from above onto a slightly sloping conveyor support.
• the feed is interrupted periodically so that discrete stacks are created directly.
• To support the stack created on the conveyor base to position the end plates and to continue conveying the entire stack in the stacking direction, three cyclically moving elements from below through the conveyor base and from above into the area of the stack are used.
• the complete stack which is conveyed onwards, is pushed into a pressing and binding station transversely to the stacking direction for the pressing and strapping, whereby it is supported at the end by stationary supports.
• the press jaws are arranged on a guide system arranged above the conveyor support, along which they can be moved back and forth parallel to the stacking direction. In addition, the pressing jaw halves can be moved transversely to the stacking direction into the stacking area and out of the stacking area.
• a stationary loop channel is provided, in which a loop of strapping material is presented in order to then be pulled out of the channel for the strapping.
• the loop channel has an input-side and an output-side, vertical part and a horizontal part connecting the vertical parts and running over a stack to be strapped.
• the horizontal channel part is arranged in such a way that it lies between the press jaw halves, which convey a stack into the strapping position.
• the vertical duct part on the entrance side is lowered under the support for this conveyance.
• the loop of the strapping material can therefore only be presented when the stack is positioned in the strapping position and the vertical channel part has moved back into its active position.
• the object of the invention is now to create a method and a device for forming and strapping lying stacks, the method and device according to the invention being simpler and more flexible compared to the prior art and allowing shorter cycle times, in particular for strapping should.
• the strapping around the lying stack, which is conveyed and pressed between press jaws into the strapping position is advantageously an advantage already presented loop of the strapping material (or a loop channel in which the loop is or is presented) is positioned.
• the loop positioning is realized by a relative movement between the loop and the stack (with press jaws), which is directed essentially horizontally and transversely to the stack direction.
• the loop or loop channel is advantageously moved against the positioned stack. So that this relative movement can be carried out with simple means, the press jaws are equipped for holding the stack from the side of the conveying pad opposite the loop provided and, if necessary, for strapping not only the stack but also the press jaws holding the stack.
• a further, essentially horizontal relative movement transverse to the stacking direction is used, this time between the strapped stack and press jaws, advantageously a movement of the press jaws from their pressing position in the stacking area into an inactive position laterally from stacking area.
• a discrete stack is thus separated from the continuously growing stack and conveyed further into a strapping position in the stacking direction between two press jaws projecting from only one side into the stack region.
• an advantageously already presented loop is positioned around the stack and the pressing jaws (movement of the loop or loop channel essentially horizontally and transversely to the stacking direction) and the stack, optionally with the pressing jaws, is strapped by tightening the loop.
• the pressing jaws are then pulled back laterally from the stacking area and the strapped stack is conveyed away from the strapping position in a suitable manner, for example transversely to the stacking direction.
• the strapping described offers a very high degree of flexibility with regard to the position and number of strapping to be carried out per stack.
• a predetermined positioning of the strapping on the stack is achieved by appropriate dimensioning of the relative movement between the stack and the loop.
• an appropriately dimensioned intermediate relative movement must be inserted between successive strapping.
• the loop can be presented in the strapping position before or during the positioning of the stack and after this positioning only has to be moved a small distance (eg approx. Half the stack width), the time required for the strapping is shorter than this is possible with a device in which the loop channel can only be brought into a functional shape after the stack has been positioned and then the loop can be presented. This means that more time is available for the movement of the stack into the strapping position, that a higher feed performance is possible and / or that shorter stacks can be produced.
• two support elements are advantageously provided which can be brought into the stacking area from below (raised, active position) and can be brought downwards out of the stacking area (lowered, inactive position) and which can be cyclically moved back and forth parallel to the stacking direction and which are designed such that they can be positioned simultaneously at the same point in the stack area, that is to say that one support element can be moved into the other support element.
