Definitions
- the present invention relates to a control device for extracting a sub-stack from a stack of paper sheets, a device for fixing a stack of paper sheets, and a de-stacking device.
- Paper processing often involves stacking and palletizing after production. During further processing, partial stacks must be produced which contain as accurately as possible a predetermined number of paper sheets. For this purpose, for example, gripping devices that remove a partial stack of the entire stack.
- a control device for extracting a sub-stack from a stack of paper sheets comprising a camera for generating a camera image, means for generating at least two substantially parallel light bundles, their reflections on the stack of paper sheets in the camera image, and means that provide a control signal for the removal of the sub-stack using the distance of the reflections in the camera image.
- the light bundles extend substantially parallel to the plane of the paper sheets.
- the control device according to the invention for the removal of a partial stack is based on a fundamentally different principle for determining the puncture point for the partial stack or other sizes than the methods known from the prior art, since it is independent of the removal of the stack of paper sheets from the camera and does not require in that the side of the stack of paper sheets facing the camera is aligned perpendicular to the camera axis.
- the number of sheets of paper between the light beams is independent of the distance of the stack of sheets of paper to the camera.
- the reflections of the two light bundles on the stack of paper sheets define a given distance, which can be used to convert arbitrary quantities in the camera image into other units of measure. This is advantageous not only for the removal of a partial stack, but also for other applications in paper processing.
- the present invention relates to a
- Apparatus for fixing a stack, in particular a sub-stack of paper sheets the means for introducing electrostatic charge into the
- the present invention relates to a destacking apparatus comprising said apparatus for fixing a stack of paper sheets and / or said control apparatus for extracting a sub-stack from a stack of paper sheets.
- a destacking device not only allows a high-precision, but also a substantially damage-free removal of a partial stack.
- the unstacking device preferably also has a parting-off mechanism with a parting-off blade, and preferably a lifting device for the stack of paper sheets, which lowers the remaining stack after tapping with the parting-off blade.
- the parting knife is preferably designed so that it can be pivoted down when lowering the rest of the stack. This has the advantage that the parting knife does not substantially damage the paper sheet lying above the parting knife when the remaining stack is lowered.
- the parting blade is pivoted down so that it is aligned substantially parallel to the overlying sub-stack.
- the knife in addition to the described possibility to pivot down also has the ability to pivot upwards. This allows one Damage-free piercing with a paper sheet bent upwards or downwards in the stack.
- the stacked paper sheets are preferably loaded above the parting knife in no phase of the removal of a partial stack of paper sheets from above. Compared to the application of a surface pressure thereby damage to the paper sheets are minimized when penetrating the parting knife in the stack of paper sheets.
- FIG. 1 shows a schematic side view of a preferred embodiment of an unstacking device according to the invention
- FIG. 2 shows a schematic view of a camera image of the camera from FIG. 1;
- Fig. 3 schematic side view of another preferred embodiment
- Embodiment of a de-stacking device having means for introducing static charge.
- Fig. 1 is a schematic side view of a destacking apparatus. It can be seen a Abstechmechanismus 20 with a parting blade 21, which takes a partial stack 12 paper sheets from a residual stack 11. In front of the stack of paper sheets is a camera 30, which takes a picture of the stack, and means for generating light bundles 41, 42, preferably laser beams, which are required for a control of the unstacking device described below.
- the desired number of paper sheets is first counted over a camera image of the stack taken by a camera.
- Image processing software analyzes the captured camera image on a suitable processing unit, for example a PC, and determines the height of the desired number of sheets of paper.
- a suitable processing unit for example a PC
- two (or more) light beams preferably laser beams
- the light bundles are substantially parallel to the plane of the paper sheets, whereby the number of paper sheets between the light bundles is independent of the distance of the stack of paper sheets to the camera.
- FIG. 2 is a schematic view of a camera image 50 of the camera 30 of FIG. 1 with a partial stack of paper sheets 51 and two reflections 52, 53 of light bundles.
- the distance 54 of the reflexes 52, 53 ie the length of the connecting line of the two reflections, can be measured in the camera image 50, for example in dimensions of the pixels of the camera image, and compared to the actual, known distance between the two light beams. This allows any sizes in the camera image to be converted into absolute distances or areas. This is advantageous not only for the removal of a partial stack, but also for other applications in paper processing.
- the height 55 of a sub-stack measured in pixels may be converted to the unit of measure of the known spacing of the light bundles, for example microns.
- the distance of the paper sheets from the camera is known.
- a measurement of this distance can be done for example by means of triangulation.
- a further laser beam 42 is used which runs at a certain angle, preferably non-parallel to the camera axis 31 (see FIG.
- the method shown in FIG shown device used. It has a lifting device (not shown), preferably a servo-controlled lifting device with backlash-free, high-precision ball spindles, as well as a parting-off mechanism 20 with a parting-off blade 21.
- the lifting device precisely approaches the piercing position determined by the camera 30.
- the parting blade 21 is then retracted exactly at this point in the stack.
- the parting knife 21 preferably has exactly in the knife axis an air nozzle (not shown), which spreads the paper exactly at the piercing position by means of air jet.
- the parting blade 21 is furthermore preferably designed such that it can be pivoted upwards and downwards in order to be able to follow the course of the paper upwards and downwards.
- the parting knife 21 is then inserted with very little force at this point in the stack. In this case, the stack is only slightly pierced in a first step.
- the paper sheets should preferably not be loaded from above in each phase of the process on the parting blade 21.
- the stack of paper sheets is driven by a further lifting device by a suitable amount down.
- the space between the abfiguring part of stack 12 and the underlying remainder stack 11 is increased, and the parting knife 21 can be further retracted into the stack.
- the parting blade 21 pivots about a suitable pivot
- the parting blade 21 is pivoted down by such an angle ⁇ that it lies substantially parallel to the underside of the sub-stack 12, which contacts the parting blade 21.
- Fig. 3 is a side view of a paper sheet fixing apparatus having means for introducing electrostatic charge 60 into the stack of paper sheets.
- the paper sheets to be removed must be precisely positioned and fixed in a predetermined position. Paper sheets, for example, highly satinated paper, but adhere very poorly. Inadvertent displacement of stacked paper sheets can therefore be prevented only by contact forces provided in the prior art by pressing the sheets. Any mechanical stress causes unwanted marks on the paper sheet.
- electrostatic charge can be introduced which creates an adhesion of the paper sheets with each other, which is independent of the friction value of a paper sheet and does not cause undesirable damage.
- the electrostatic charge is preferably introduced contactlessly into the stack of paper sheets and is preferably metered so that a substantially predetermined number of paper sheets is fixed, preferably a partial stack 12 to be removed or a remaining stack 11 of the paper sheets ,
