Definitions

  • the invention relates to a method and a device for recognition product defects on envelopes, mailers and the like during their manufacture in one of several stations and / or Machine components existing production machine.
  • object The invention is therefore a product monitoring in the form of an inline quality control.
  • the invention provides that at least two or three characteristic sizes checked during production and the production machine based on the test results Orders are given in such a way that an improper one manufactured or defective product immediately removed and / or is marked so that it is recognizable for the operating personnel and can be removed and the error can be rectified.
  • each one Product is recorded with the result that the faultless products end up ejected from the production line or sorted out become.
  • Line cameras are preferably used for monitoring provide a striped image of parts of the product. But also different types of sensors are provided depending on the intended use.
  • At least one characteristic size of the product in terms of location and shape and / or multiple sizes relative to location and shape to each other permanently and - as in the first case - with stored target quantities compared, so that the result of the comparison can then be used for further measures.
  • the target sizes it is either a given and / or a learned one Values or sizes. In this way it is possible Defects on products immediately at the time of creation recognize if these may not yet affect the further Production may have impacted. It is also possible that reject defective product and the cause of the error immediately remedy. Safe and reliable production can therefore be found in perform much higher than before.
  • Manufacturing production machines 1 ' is a device 2 according to 1 and 2 and includes one or more sensors in the form of line cameras 3, 3 ', each with an associated light source 4, 4 'and / or capacitive sensors 5, 5'.
  • Imaging Sensors are particularly used to monitor and inspect the Glue provided on the side flaps while capacitively working Sensors especially for the inspection and monitoring of the glue on the End flaps serve.
  • the line scan cameras 3, 3 'and the capacitive sensors 5, 5' give signals to an evaluation electronics 6.
  • An encoder 7, the one Measuring wheel can be assigned to the evaluation electronics 6 connected and basically the same applies to a clock disc 8 to the a clock initiator and a clock shaft 9 connected to the machine belong.
  • the output signals of the evaluation electronics 6 carry along Using control electronics 10 for control signals on an ejector 11, which feeds the defective products 12 to a waste container 13.
  • the control electronics 10 can also be a Control marking device 14, with the help of which the defective products 12 'are first marked so that they can then be manually can be removed.
  • Station 15 is a printing station in which a certain text or an image on the still web-shaped Starting material 16 can be printed. Here are the exact ones The position of the text or the images was determined.
  • the window material 19 is in a subsequent station 17 (arrow B) (Fig. 1 and 3) in the case of a window 18 Envelope on a part of the window completed envelope 1 or on a Intermediate product 20 is arranged and is in terms of size and location checked with at least one line camera 3.
  • the glue traces 24 are then scanned on the End flaps 25 (arrow D) in the region of the end flap folding station 26 or at the entrance to a drying line.
  • the largely Completed envelopes 1 pass through the tail flap folding station 26 in a staggered position, as can be seen from FIGS. 1 and 6.
  • the marking according to arrow F can also continue in a variable manner at the front of the production line, so that in particular the Marking is made before the faulty product goes to the Ejector 11 arrives.
  • Machine components can be found in the area of the individual stations are difficult to monitor with the help of sensors is. So z. B. in the area of gluing the window material 19 serving station 31 different machine components like this be arranged that an interference contour 32 must be observed.
  • This Interference contour 32 is only schematically indicated in FIG. 3 with a contour line 33 and requires that one serving as a sensor Line camera 3 only at an angle to the product to be monitored or specifically to the partially completed envelope 1 and not can be arranged perpendicular to the product.
  • FIG. 3 shows the optical sensor or the Line camera 3 arranged offset to the product to be monitored and with their optics 34 from that too monitoring product averted. Furthermore, a plurality of mirrors 35, i. H. in the present case, five mirrors 35 are specifically provided and provided that the beam path 36 of the image representing the product first recorded perpendicular to the product and finally also falls axially parallel into the optics 34 of the line scan camera 3. Both the Line camera 3 and the mirror 35 are located Expediently in a housing 37, the outer contour of which considering the interference contour of station 31 still available standing space is adjusted. In the specific case shown in FIG. 3 this leads to the beam path 36 being a beam path 38 has, which is almost parallel to the axis 39 of the optics 34 of the Line camera 3 runs. The one caught by the first mirror 35 The image is therefore deflected several times before it can be evaluated.
  • a plurality of mirrors 35 i. H. in the present case, five mirrors 35 are specifically provided and provided that the beam path 36 of the image representing the
  • the components shown in FIG. 3 are one Monitoring device 43 with an image deflection. It serves concretely to monitor the proper manufacture of the window 18 in finished product.
  • Each imaging sensor 5 has one Line scan camera 3 and a light source 4, as shown in FIG. 5.
  • An imaging sensor 5 is provided for each glue track 22.
  • the line scan camera 3 and the light source 4 are expediently shown in Direction of movement of the almost completed envelope 1 arranged in series, as shown in Fig. 5. Basically, variants are also conceivable.
  • the traces of glue 24 on the closing flaps 25 are monitored expediently with the aid of several sensors 5 ' scan one or more glue traces 24 at a time.
  • This Sensors 5 ' are expediently capacitively operating sensors.
  • a sensor 5 ' is located above each of the two ends of the glue traces 24 arranged, while a third sensor 5 'is located approximately in the middle above the or the glue traces 24.
  • the sensors form a common one Monitoring device 43.
  • the Production machine 1'd serves as a counter electrode.
  • Characteristics it is possible to have one or more characteristic quantities of the product in terms of length and / or shape or in terms of location and / or form to be recorded relative to each other and with to compare stored target values so that the result of the The comparison can then be used for further measures.
  • the result can be displayed and / or used for corrective actions and / or used to mark the product and / or documented and / or to discharge the product from the production machine be used.
  • the invention is not specific to the above based on the figures measures described and in particular not limited to the monitoring of the glue traces is limited because other sizes such as the edges of the window openings in the cut and other cutting lines can be monitored advantageously.
  • the invention is not intended to be used together with Production machines for envelopes, envelopes, envelopes and the like. Also in machines and / or stations for Die cutting of envelopes and mailers or in Interpfalz-, handkerchief, napkin machines can be imaging and / or use capacitive sensors.
  • sensors of various types can be used for monitoring Results from printing presses are used in conjunction can be used with the machines already mentioned above.
