Definitions

  • the invention relates to a device for forming stacks of flat products with a first transport section for transporting a stream of individual flat products of a first type, a second transport section for forming a scale flow of the flat products of the first type and a stacking unit for forming individual stacks of the scale flow.
  • Devices for carrying out this process are also referred to as automatic displays. Such devices are manufactured, for example, by the applicant and marketed under the type designation delta700.
  • a method and an apparatus for feeding a series of flat bodies is known to a stack, wherein the flat body along a first transport path (I) first transported one behind the other, then braked and thereby brought into an overlapping arrangement and transported with reduced transport speed to a stacking station.
  • the row of flat bodies can be branched from the first transport path (I) to a second transport path (II) and returned from the second transport path (II) to the first transport path (I), the length of the second transport path ( II) and / or the transport speed along the second transport path (II) are selected such that in the series of flat bodies between the end of the still along the first transport path (I) transported part of the row of flat bodies and the beginning of the second transport path (III) branched off part of the series of flat body is generated an interruption.
  • the stacks formed in this way in particular when they are made of flexible flat products, have the problem that they themselves are limp and often fold over very quickly, which makes them difficult to handle and can also lead to damage to the sheet-like products.
  • the object is achieved in that on the device for forming stacks of flat products, a supply unit for flat products of a second type is present, wherein the feed unit introduces the flat products of the second type inline in the flow of the individual sheet products of the first type wherein the feeding unit inserts two directly successive two-dimensional sheet products between the sheet-like products of the first type, and wherein with the stacking unit the flow of shingles between the two successive sheet-like products of the second type is separable such that a first sheet-like product of the second type covers the lid a leading stack and a second sheet of the second type forms the bottom of a trailing stack.
  • step b of transporting the stream of individual flat products of the first type at least one flat product of a second type becomes part of the flow of the flat products of the first type introduced, wherein in step b, two directly successive sheet-like products of the second type are introduced into the flow of the sheet-like products of the first type, and wherein in step d the shingled stream is separated into stacks such that a first flat product of the second type covers the lid of a leading stack and a second sheet of a second type forms the bottom of a trailing stack.
  • sheet product means all products whose thickness is many times lower than their length and width. This includes in particular flat paper and cardboard products such as printed products, but also sheet-like plastic or metal products.
  • These sheet products can be of any type, wherein the sheet-like products of the first type differ in at least one feature from those of the second type.
  • This feature may be e.g. the form, the material but also the imprint.
  • the flat products inline By feeding the flat products inline, they can be introduced at the same speed with which the individual flat products of the first type move onto the transport section. Thus, there is no delay in introducing the flat products of the second type, since the distance between the flat products of the first type can be used for introducing the flat products of the second part, without any braking of the first transport section would be necessary.
  • the feeder can be arranged in parallel above the first conveying portion so that no elongation or broadening of the device of the apparatus occurs. This allows a particularly compact design.
  • the feed unit can have any shape known to those skilled in the art and consists, for example, of a separating device and a conveyor belt.
  • the feed unit introduces the flat products of the second type into the flow of the individual flat products of the first type at an interface between the first transport section and the second transport section.
  • the first transport section has a first conveyor belt at a first speed and the second transport section has a second conveyor belt at a second speed, wherein the second speed is lower than the first speed.
  • the device further comprises a synchronization unit, which synchronizes at least one of the transport sections and in particular both transport sections with the feed unit.
  • Synchronization in the sense of the invention is to be understood here as meaning that the position and / or speed of a flat product is determined at a point of the transport sections or the feed unit and the feed unit or the transport sections are activated as a function of this determined position and / or speed ,
  • a synchronization in the above manner ensures that always the same size stacks are formed.
  • the introduction of the flat products is synchronized with the transport of the flow of the flat products of the first type so that a flat product of the second type comes to rest approximately on a flat product of the first type.
  • the transport of the scale flow is synchronized with the feeding of the flat products of the second type.
  • the stacking device has a holding arm.
  • a holding arm has proven to be a mechanically particularly simple embodiment of the stacking device, which operates safely, in particular even at high production speeds.
  • a device for forming stacks of flat products of the entirety is designated by the reference numeral 10.
  • the device 10 has a first transport section 12 in the form of a first conveyor belt 14.
  • Flat products of a first type 16, in this case printed and folded flyers, are transported on this conveyor belt 14.
  • a second transport section 18 in the form of a second conveyor belt 20 connects.
  • a scale flow 22 is arranged from the flat products of the first type 16.
  • a feed unit 26 is arranged.
  • This feed unit 26 has a support 28 on which flat products of a second type 30, in this case solid cartons, are arranged.
  • the support 28 is inclined, so that the cartons 30 slide against a stop 32.
  • the stop 32 has on its underside a slot 34, wherein the height of the slot corresponds to the thickness of a carton.
  • the cartons 30 are held in their current position by friction with each other.
  • the feed unit 26 also has a movable driver 36 which is reciprocable in the direction of a double arrow 38.
  • a movable driver 36 which is reciprocable in the direction of a double arrow 38.
  • an upper edge of the movable follower 36 projects beyond the top of the overlay 28 through a slot in the overlay 28. This slot extends in the drawing planes and allows the movement of the driver 36 in the direction of the double arrow 38.
  • the driver 36 protrudes at a height beyond the support 28, which corresponds to the thickness of a carton.
  • Both the height in which the driver 36 protrudes beyond the top of the support 28, and the height of the slot 34 are adjustable. As a result, flat products of different thickness can be supplied with the feed unit 26.
  • the conveyor belt 40 detects the carton and inserts it directly at the interface 24 between the first transport section 12 and the second transport section 18 into the flow of the flat products of the first type 16.
  • the feed unit is in this case synchronized with the first transport section 12 that after a predetermined number of flat products of the first type 16, in this case after nine such products 16, two flat products of second type 30 are introduced into the flow of the flat products of the first type 16.
  • This stacking unit 42 has a holding arm 44 and a stacking container 46.
  • the flat products of the first type 16 are now moved in the direction of an arrow 48 on the first conveyor belt 14 in the direction of the second transport section 18. Since the second conveyor belt 20 is operated at a lower speed than the first conveyor belt 14, there run the flat products of the first type 16 on each other and form the scale flow 22nd
  • the number of sheet-like products of the first type 16, which are transported on the first transport section 12, is detected. If a predetermined number of sheet-like products of the first type 16 is reached, it is calculated by a synchronization unit when the last desired sheet-like product of the first type 16 reaches the interface 24.
  • the feed unit 26 is then controlled so that at this time automatically two flat products of the second type 30 in the direction of an arrow 50 in the flow of the flat products of the first type 16 are introduced.
  • an imbricated stream 22 is formed from a plurality of flat products of the first type 16, which are each interrupted at a predetermined distance from two flat products of the second type 30.
  • This scale flow 22 is now moved in the direction of an arrow 52 on the second conveyor belt 20 in the direction of the stacking unit 42. If two successive two-dimensional products of the second type 30 reach the stacking unit 42, then the holding arm 44 is introduced into the shingled stream 22 in such a way that it grips and holds back the second flat product of the second type 30.
  • the remainder of the shingled stream 22 is discharged in the direction of the arrow 50 into the stacking container 46, where it forms a stack 54 of flat products of the first type 16, each of which is bounded above and below by a flat product of the second type 30.
  • This stack 54 can then be further processed directly in the stack container, e.g. be banded or packaged, or may be removed from this container and further processed in a further step.
  • a device for forming stacks of sheet products is designated in its entirety by the reference numeral 60.
  • the device for forming stacks of flat products 16 has a first transport section 62 for transporting flat products of a first type 66.
  • the first transport section 62 is adjoined by a second transport section 68 for transporting an imbricated stream 72 of flat products.
  • the apparatus 60 further comprises a feed unit 76 for feeding flat products of a second type 80.
  • the second transport section 68 is followed on the right side by a stacking unit 82, which consists of a holding arm 84 and a stacking container 86. This stacking unit 82 serves to form individual stacks from the shingled stream 72.
  • planar products of a first type 66 are now transported on the first transport section 62 at a speed V 1 from left to right, ie in the direction of the second transport section 68.
  • the second transport section 68 transports the flat products of the first type 66 at a speed V 2 that is less than the speed V 1 of the first transport section 62. As a result, the flat products of the first type 66 are pushed over one another and form the shingled stream 72.
  • the device 60 further comprises a detection unit for detecting the flat products of the first type 66.
  • this detecting unit determines the position of the first-type sheet 66 'which is to form the last one of the first-type sheet 66 of a stack. From the determined position and speed, the time at which the sheet of the first type 66 arrives at the point where the sheet of the second type 80 is fed is calculated.
  • the feed unit 76 then accelerates two flat products of the second type 80, 80 'to a speed V 1 in such a manner that the first of the two flat products of the second type 80 coincides with the flat product of the first type 66' on the Feeding position arrives. Due to the fact that the two flat products 80 and 66 'arrive at the same position at the same time, they come to rest on each other in an approximately covering manner during feeding. Because they are moved at the same speed, there is no slippage.
  • FIG Fig. 3 The state of the system after feeding the first sheet-like product of the second type 80 is in FIG Fig. 3 It can be seen from this that the flat product of the first type 66 ', which is to form the last flat product of the first type 66 of a stack, and the first flat product of the second type 80 have come to lie approximately concisely on each other.
  • the shingled stream 72 bounded on the right side by a second-type front sheet 80 "and on the left-hand side by the second-type sheet 80 is further moved by the second transporting portion 68 toward the stacking tray 86.
  • the feed unit 76 introduces another second-type sheet 80 'to be inserted between the second-type sheet 80 and a first-type sheet 60 "in the shingled stream 72.
  • the shingled stream 72 becomes further to the right transported.
  • the flat product of the second type 80 ' has come to rest on the flat product of the second type 80 and is transported together with this within the scale flow 72 to the right.
  • Fig. 5 the situation is shown after a further transport of the scale flow to the right.
  • the flat product of the second type 80 "and five successive flat products of the first type 66 of the scale flow 72 have fallen into the collecting container 86 and have formed there a stack 88.
  • the holding arm 84 folds down in the direction of the arrow 90.
  • the holding arm engages the flat product of the second type 80 ', which is to form the bottom of the next stack, and holds this back.
  • the scale flow 72 is separated into individual stacks which are delimited at the top and bottom, ie in the form of a bottom and a lid, by flat products of the second type 80.
  • the second transport section 68 now transports the flat product of the second part 80 in the direction of the collecting container 86 in order to complete the stack 88 there.
  • This condition is in Fig. 6 shown. It can be seen that the flat product of the second type 80 'and thus the scale flow 72 is retained by the holding arm 84. Now, if the stack 88 completed in the stack container 86, this can either be directly banded or packaged there, or can be removed from it and further processed elsewhere. Once the stack 88 is removed from the sump 86, the support arm 84 is folded up in the direction of the arrow 92 and releases the shingled stream 72.
