Definitions
- the invention is in the field of further processing of printed products and relates to a device and a method according to the preambles of the corresponding independent claims for the detection of errors in a shingled stream, in particular in a shingled stream consisting of printed products (US-A-3 826 487).
- shingled streams are monitored by measuring their thickness in various ways, for example with a deflectable measuring wheel that rolls over the surface of the shingled stream and whose deflection is evaluated as a measure of the thickness of the shingled stream relative to the support of the shingled stream.
- a corresponding device is described, for example, in EP-A-0 242 622.
- fault locations in the scale flow can be identified.
- Such monitoring is particularly suitable in large scale streams, that is to say in those in which only the edges of successive products lie on one another and each product lies neither on nor below another product in a central region.
- the object of the invention to provide a method and a corresponding device with which it is possible, without moving the products in the shingled stream in any way specifically for the measurement, to identify more different types of defects in more different shingled stream environments than is possible with corresponding arrangements according to the prior art.
- it should also be used in very narrow scale streams, in which several printed products lie on each other at each point, and both in scale streams of flexible printed products, for example newspapers, which adapt to the shape of the scale stream, as well as of stiff printed products, for example stapling with stiff cover sheets, be able to detect errors more reliably and identify them more precisely.
- the surface of the scale flow is continuously scanned at two closely spaced measuring points arranged one behind the other in the conveying direction, the level difference of the two scans being measured.
- This difference is very small or zero as long as the two sampling points are on the same product. It becomes large if there is a product edge between the two scanning points.
- the method and the device can be applied both to scale streams with product edges at the top and with product edges at the top.
- the thickness of each product is actually measured across its edge on the surface of the scale stream, regardless of the thickness of the other products below the product and therefore independent of defects in these products.
- a thickness error as a result it also becomes larger in percentage terms than when measuring the thickness of the entire current.
- the edge can also be recorded precisely in time, so that clock errors can also be determined.
- the device according to the invention has a probe element and a measuring element, the probe element and the measuring element sensing the scale flow and the measuring element being designed at the same time in such a way that it measures the difference between the two scans.
- the shingled stream shown in line a has defects: in cycle T.7 a product is missing, cycle T.9 two products appear, cycle T.10 one product is missing and cycle T.13 shows a quarter of the cycle time late product.
- the clocks T.1 and T.2 or T.16 and T.17 also have irregularities, since they represent a beginning of a stream or an end of a stream.
- Lines b and c now represent measurement signals from thickness measurements over the entire scale flow (prior art). For the time being, only the solid signal curve is to be considered; an explanation of the dotted signal curve follows in connection with the description of lines e and f.
- Line b shows the signal curve of a distance measurement between the support and the shingled stream surface, specifically in the case of a shingled stream made of extremely flexible printed products which completely adapt to the contour of the shingled stream and which lie on top of one another in such a way that there are no gaps under the shingled stream at any point in the shingled stream or occur between the printed products.
- a corresponding signal course is described in EP-A-0 242 622, already mentioned at the beginning, the course of the signal between values 2 and 3 being used for monitoring the scale flow. From this signal curve, as line b shows, an empty space (T.7) can be recognized as an error location.
- the extended signal curve of line b when compared with a proper signal curve, as occurs, for example, in cycles T.3 to T.5, identifies the following cycles as error points: (T.1, T.2), T.7, (T.8), T.9, T.10, (T.11, T.12), T.13, (T.15, T.16, T.17) , but the measures in brackets effectively have no errors.
- the first time an error occurs it must be assessed according to type and then the target course for all other cycles, to which the error extends, must be adjusted accordingly, which is obviously associated with a large amount of calculation.
- Line c shows (drawn out) a signal curve generated using the same method as line b.
- a scale flow of stiff products is measured, in which the products lie at an angle to one another and gaps arise under the individual products, i.e. a scale flow as effectively shown in row a.
- the signal curve is very different compared to line b and that it should be difficult to monitor the two curves, which in principle represent the same scale streams, with the same signal evaluation.
- Line d represents the signal curve which is obtained with a method and a device according to EP-A-0 479 717, also cited at the beginning, when measuring the scale flow shown in line a.
- the synchronization between the current and the measurement is such that the reference surface is positioned under the product in the second eighth of the cycle time and the thickness of the product is measured in this period.
- the error points in clocks T.7, T.9 and T.10 are simple and corresponding Type of fault location can be detected and interpreted.
- the fault location in cycle T.13 leads to an incorrect interpretation, namely that of an empty space.
- a wrongly clocked product is interpreted either as a blank or as a correct product depending on the size of the shift and the arrangement of the measuring time within the clock. From the signal curve of line d it can also be seen that the beginning of the shingled stream (T.1 and T.2) and the end of the shingled stream (T.16 and T.17) can be interpreted without errors and without any computational effort.
- the extended signal curve is to be understood as an ideal measurement of the scale flow thickness at a first measuring point M.1, the dotted curve as a measurement of the same scale flow thickness at a second measuring point M.2, with each scale flow element first is conveyed past the first measuring point M.1, then past the second measuring point M.2.
- the distance d between the two measuring points corresponds to a quarter of the edge distance D or temporally a quarter of the cycle time T, a ratio that was chosen for reasons of illustration only.
- the dotted waveform is exactly the same as the solid waveform, but shows a phase shift that corresponds to distance d.
- the difference between the two signal profiles is measured. These are shown in lines e and f. It can be clearly seen from the two lines e and f, which, in accordance with lines b and c, in turn represent the signal curve for a shingled stream of flexible products and a shingled stream of rigid products, that the two profiles are not fundamentally different in the first half of the cycle differ, but essentially only by their position relative to a zero line, so that they can be easily interpreted with the same evaluation.
- FIG. 2 shows in the same schematic representation as FIG. 1 the influence of the distance d between the measuring points M.1 and M.2 on the signal curve generated by the method according to the invention, parts selected from a scale flow in a line g and h in a line h corresponding measurement signals corresponding to line f of Figure 1 are recorded.
- Case A shows that the distance d between the two measuring points M.1 and M.2 must be greater than the extent of the edge in the conveying direction.
- the edge height can only be clearly determined with such a large measuring point distance, since in one certain point in time that one measuring point has already passed the edge while the second has not yet reached it. It is ideal if the measuring point M.2 is positioned immediately in front of the product edge when the measuring point M.1 has scanned the entire product edge and has just reached the highest point.
- Cases B, C, D and E show that the detection of multiple products (in the representation of double products) depends on the ratio of the distance between the two measuring points M.1 and M.2 and the distance of the detected edges of the individual products of the double product.
- the four cases have the same distance d between the measuring points M.1 and M.2 and different edge distances k.
- the double product produces a signal deflection with double the height and the same shape compared to the target deflection for a simple product.
- k ⁇ d case C
- there is a graded deflection that can be interpreted with a correspondingly precise measurement and evaluation.
- With k d (Case D) there is an excursion with twice the latitude and for k> d (case E) there are two excursions which are to be interpreted as a time-shifted product.
- FIG. 2 also shows that differentiated scale flows can also be monitored with the method according to the invention.
- Differentiated scale flows are scale flows in which products are conveyed in groups, the edge distances within the groups being smaller than the edge distance between the last product of a group and the first product of the following group. If, for example, the distance between the measuring points M.1 and M.2 is selected in such a way that it corresponds to the target edge distance within the group, a time-wise deflection is generated for a group (according to case D), as is the number of products in the group. If the distances are too large, separate rashes occur according to case E, if it is too small, rashes graded according to case C arise, both of which can be detected as defects.
- Figure 3 now shows an exemplary embodiment of the device for performing the previously described inventive method. It is a device with a double scanning roller, the deflection of the second roller compared to the first roller being evaluated as the differential measurement signal.
- a first feeler roller 11 is arranged on an arm 13 so as to be freely rotatable about a first axis of rotation 12, the arm 13 being arranged so as to be pivotable about a first pivot axis 14 arranged in a stationary manner.
- a second feeler roller 21 is arranged in a freely rotatable manner about a second axis of rotation 22 on a lever 23, the lever 23 being fastened on the arm 13 so as to be pivotable about a second pivot axis 24.
- the arm 13 is arranged relative to the contact surface 30 of a shingled stream 31 such that the first sensing roller 11 rests on the shingled stream surface and is slightly pressed onto this surface by the weight of the arm 13 and / or, for example, a spring force.
- the feeler roller 11 rolls on the shingled stream surface.
- the lever 23 is arranged on the arm 13 in such a way that the second sensing roller 21 also rests on the scale flow surface, specifically in such a way that the support points of the two rollers are at a distance d from one another in the conveying direction.
- the second feeler roller 21 is also lightly pressed onto the scale stream surface, for example by a spring.
- the second sensing roller 22 is in a middle pivoted position as long as there is no product edge between the support points of the two sensing rollers (measuring points). If there is a leading edge between the two support points, as shown in the figure, the lever 23 is pivoted in the direction of the arrow S with respect to the central pivot position, and the higher the edge, the more so. A trailing edge between the two support points causes a pivoting in the opposite direction. The pivoting of the lever 23 is absolutely independent of the total thickness of the scale flow and therefore not dependent on the fluctuations in the deflection of the first sensing roller.
- the pivoting of the lever 23 In order to monitor the edges of a shingled stream, the pivoting of the lever 23 must be measured.
- the lever 23 is designed as a two-armed lever with a roller arm 23.1 on which the second Probe roller 21 is attached and a measuring arm 23.2, which is arranged such that it actuates a probe 40 when pivoting, which is shifted depending on the pivoting position of the lever 23 in the direction of arrow L and provides a measurement signal corresponding to this shift.
- the pivoting of the lever 23 can also be limited by a stop 41 in such a way that it can only be pivoted in one direction from the middle position (same contact level of the first and second sensing roller).
- the button of the illustrated embodiment will accordingly only register leading edges, while it does not detect rear edges, since a lower level of the second sensing roller 21 relative to the first sensing roller 11 is prevented by the stop 41.
- the device can be adapted to different applications, it is advantageous to design it in such a way that the distance between the support points of the first and the second sensing roller can be adjusted.
- This can be achieved, for example, by a lever 23, the length of which can be adjusted.
- the deflection of the second sensing roller can also be measured using other means, for example an angle encoder.
- the function of the second sensing roller can also be taken over by a distance meter which is firmly connected to the arm 13 and is arranged at a distance from the support point of the first sensing roller 11. This distance meter can function without contact, for example optically.
- Figures 4 and 5 show a further embodiment of the device according to the invention. Compared to the embodiment according to FIG. 3, this is better adapted for monitoring scale flows of very different thicknesses and for monitoring scale flows from very thick products. It can be seen from FIG. 3 that the thickness of the scale flow which can be measured with the device is limited by the distance between the pivot axis 14 and the shape of the arm 13. In the case of a thick scale flow (arm 13 pivoted upwards strongly), the printed products become with the lower one Edge of the arm 13 come into contact, which must be prevented.
- the device has a second feeler roller 21, which can be freely rotated about an axis of rotation 22 arranged on a lever 23.
- This lever 23 is in turn pivotable about a first pivot axis 24 on an arm 13 ', this arm 13' having the same function as the arm 13 of the embodiment according to FIG. 3. It is therefore pivotable according to the thickness of the scale flow and carries the first measuring point M.1.
- the arm is designed as a parallel pair of levers 41.1 and 41.2 with a holding plate 42.
- the two parallel levers 41.1 and 41.2 are each pivotable about a fixed pivot axis 43.1 and 43.2 and in turn each carry a further pivot axis 44.1 and 44.2, which are arranged spatially relative to one another in the same way as the pivot axes 43.1 and 43.2.
- the holding plate 42 is pivotably arranged on the pivot axes 44.1 and 44.2.
- the device according to FIGS. 4 and 5 is adapted for the monitoring of scale flows from dense printed products (high product edges).
- the function of the first sensing roller 11 of the embodiment according to FIG. 3 corresponds to a pair of rollers 45.1 and 45.2, the two rollers of which are arranged on the holding plate 42 in a freely rotatable manner about the axes of rotation 46.1 and 46.2.
- a probe tape 47 for example a fine toothed belt, runs over the pair of rollers 45.1 and 45.2 and rolls on the scale stream passing under the measuring arrangement.
- the probe tape 47 lies in the area of the roller 45.1 on the scale stream (extended position in FIG. 5) until the measuring arrangement approaches a high edge. This comes into contact with the touch tape 47 between the two rollers 45.1 and 45.2 (positions 45, 1 'and 47' shown in dash-dot lines in FIG. 5), whereby the roller 45.1 is raised to the level of the edge.
- An arrangement with a touch tape 47 instead of a single first touch roller (11, FIG. 3) is a continuous movement over the stream of shingles ensured.
- a single tracer roller could get stuck on very high product edges, which could lead to discontinuities in the signal curve and to product shifts in the stream.
- the measuring arrangement is to be designed in such a way that the angle between the scanning tape 47 and the contact surface 30 is small enough to ensure a continuous movement of the measuring arrangement, but on the other hand it is large enough to still be able to reliably detect an edge. good results have been obtained with an angle ⁇ of approximately 15 °. As already described, this angle ⁇ can be kept constant regardless of the scale flow thickness by using an arm 13 'which has a pair of parallel levers (41.1 and 41.2) and a holding plate (42).
- measuring arrangements are also conceivable that have a simple arm and a feeler tape, or those that have an arm with a parallel lever and holding plate and a simple first feeler roller.
