Definitions

  • the invention relates to a device and a method for separating flat packages according to the The preamble of claim 1 or of the claim 9th
  • the present invention relates to the field of postal automation.
  • the separation of flat packages is demanding in that not only the physical sizes of flat packages vary widely, but also the nature of these packages is very different.
  • the physical quantities refer to the width, height and thickness, mass and the derived from the material of the packages properties such as coefficient of adhesion or sliding friction.
  • the type of packages relates to any packaging and the rigidity of flat packages.
  • advertising broadcasts are to be considered here, which are to be found in very different design such as: A simply folded free newspaper, in the fold additional different brochures are inserted.
  • the weight of these brochures, these additions are also called “inserts", relative to the newspaper take a considerable extent, since the brochures often provided a much better paper quality. This is also expressed in a correspondingly higher mass per unit area: for example, 120-140 g / m 2 for the leaflets compared with about 40-60 g / m 2 for the newsprint.
  • packages are flat packages such as e.g. Letters, brochures, Pattern subsumed in preferably rectangular shape.
  • Facilities for the separation of flat packages are for example, known from document EP 1 052 207 A1 (Applicant: Grapha-Holding AG) and EP 1 065 160 A1 (Applicant: Grapha-Holding AG). These are not suitable for the The aforesaid packages, as these are only vertical here Device can be fed. For reasons of relatively high masses the packages considered here and low mechanical Strength of the outer parts such as e.g. a newspaper can this device will not be applied. Therefore, it is required the packages stacked in horizontal layers to feed the device.
  • the present invention is therefore based on the object an apparatus and a method for separating packages indicate, regardless of the masses, Proportions and characteristics of the packages a safe Separate and a high throughput is possible. Under safe separation is here in particular the prevention meant by double prints as well as that the packages when singling neither damaged nor unintentionally folded or even destroyed.
  • a finger pivotable about a shaft which engages the stack in a package to be removed and has an air outlet at the tip of the finger through which air exits to generate an air cushion between two adjacent packages; a device is created that safely separates packages regardless of their masses, proportions and properties.
  • Figure 1 shows a cross section through a device 1 for Separation of flat packages 10.
  • the packages 10 are placed in batches in the magazine 2.
  • This magazine is by a stop 7 and a preferably sizing the packages 10 customizable, i. displaceable Wall 6 formed. Is it the packages? For example, to a folded newspaper, the contains more leaflets ("inserts"), the pile is inserted so that the fold on the left, that is the sliding Wall 6 opposite side comes to rest.
  • a wall 7 is shown, to the width of the products and thus to the Width of the stack is slidably applied.
  • the embodiment The present invention relates with respect to the specified withdrawal drum 3 with gripper 4 the device specified in document EP 0 261 354 B1.
  • the device has the withdrawal drum 3, which in the counterclockwise direction rotates.
  • At the periphery of the take-off drum 3 at least one actuatable gripper 4 is arranged, the after grasping a package 10 by e.g. suckers 5 of the package detected by a "reverse clamp".
  • a package 10 by e.g. suckers 5 of the package detected by a "reverse clamp”.
  • suction cups 5 whose position is indicated in FIG. 1 by the reference numeral 5 shown
  • the axis of rotation of this pivoting movement is not shown in Fig. 1.
  • at least one finger 20 is provided, the between the package to be withdrawn and the next intervenes.
  • the fingers 20 and the suction cups 5 provide several times on their respective waves.
  • Fig. 2 shows a detailed structural design of the Finger 20 in a first embodiment.
  • the feeder of Air is supplied via hoses connected to an air supply flange 26 are connected to the finger 20.
  • Finger 20 points a flange 28 through which a fastener 25th engages to make a firm connection with the shaft 24.
  • the screw 23 is here as a closure screw provided, one located inside the finger 20 Air duct closes, the opening is made of manufacturing technology Reasons unavoidable.
  • FIG. 2a The location of the air outlet opening 29 and leading to it Air duct 27 is shown in Fig. 2a.
  • This Fig. 2a is used to a particular embodiment of the present invention at the tip of the finger 20 may be additional a roller 21 rotatable about an axis 22 may be provided.
  • the roller 21 only rotatable in one direction, namely as shown in Fig. 2a in Direction d or clockwise. These possible in one direction Rotatability of the roller 21 is also referred to as a freewheel.
  • Fig. 3a is a stationary state before pulling off a Package 10 shown.
  • a stack of packages 10 lies on a support 9.
  • the denoted by the reference numeral 9 illustrated edition is not the only edition for the Stack.
  • the finger 20 about the axis 24 (In Fig. 3a and 3b not shown) down earlier than the Suction cup 5.
  • the suction cup 5 pulls the bottom package 10th away from the stack into a position such that a gripper 4 of the Trigger drum 3 can pull the package out of the stack ..
  • the finger 20 in the "horizontal" Retracted position (not shown in Figure 3b).
  • an air supply approximately in the direction represented by the reference f. It will an air cushion between the two packages concerned 10 generated so that the package to be withdrawn 10 only a very low friction to the immediately above lying package 10 has. This can do that so-called rolling up of the overlying package 10th be very effectively prevented.
  • Throughout Movement of the finger 20 may be an air supply. It is also possible to adjust the air supply depending on the location of the Fingers 20 to steer, that is in the downturned Condition to interrupt or at least go back. in the still swung out area of the finger 20 presses the Air flow the package 10 in addition to the suction cup 5.
  • the roller 21 therefore has a freewheel, so that at Retraction of the finger and especially in thick Packages 10 of the fingers themselves, the package 10 is not touched and that the role because of its rotation the withdrawal package not exciting or skewered and destroyed by it. Only after deduction of a package 10th through the at least one suction cup 5 is in a later Phase the package 10 by one on the trigger drum. 3 attached gripper 4 detected and further promoted.
  • the "blocking" direction of rotation of the roller 21 is the lowest package 10 in the stack close to its pad an additional stop.
  • the Fingers 20 may be provided, this only substantially to perform an angle as shown in Figures 3a and 3b is shown.
  • This trained as an angle finger also has an air channel 27 and an outlet opening 29 on.
  • the air is over the trained as a hollow shaft Shaft 24 is supplied.
