Definitions

  • the invention relates to a method and an apparatus for Manufacture of packs, in particular cigarette packs, from blanks of a packaging material, in particular paper, thin cardboard or the like, being a web of material or individual cuts of the packaging material along a Conveyor track to be transported.
  • the blanks of the packaging material can be cut either pre-cut the packaging machine provided in blank stacks especially with hinge-lid packs for cigarettes, or cuts are made within the packaging machine of separated from a material web.
  • the high demands on the Quality and correct training of the packs require multiple Monitoring and controls of the packaging material.
  • the invention has for its object an effective, powerful monitoring of packaging related to suggest using packaging machines that are permanent works flawlessly.
  • the monitoring body equipped with sensors serves primarily Line for the detection of defects on the material web or on the Cut. However, the monitoring bodies can also apply to others Address characteristics of the packaging material, for example Marks attached to the packaging material to control Organs.
  • the monitoring bodies work with light signals, in particular with a light beam as a test beam.
  • the perfect way of working Such monitoring bodies depend on the fact that the light-emitting and / or light-receiving sensors are in perfect condition. Deposits of dust and prevent or prevent other contaminants the way of working.
  • the invention is a permanent in a simple manner automatic cleaning achieved by the packaging material itself, namely through the material web or the individual cuts, which are passed over the sensors below Plant on the outer, free surface of the same. Through this Contamination is constantly removed or their deposition on the sensors is prevented.
  • Material web or blanks are used to carry out the method transported along the conveyor track having guides.
  • the monitoring bodies are preferred U-shaped, namely as a so-called fork light barrier with two legs spaced apart, between which the packaging material is passed becomes.
  • the sensor in the area of the lower leg is impacted by the packaging material as a result of the system.
  • the monitoring bodies are according to the invention in a special way trained, namely consist of a solid body with cavities to accommodate optical and possibly electrical conductive organs, which are covered by an investment within the Cavities are fixed.
  • FIG. 1 is an advantageous embodiment and application example reproduced, namely the handling of blanks 10 made of packaging material, namely thin cardboard.
  • the blanks 10 are those for one Collar of a hinge-lid cigarette pack.
  • the otherwise manufactured blanks 10 are along a Conveyor track 11 transported. This can be horizontal or in run on an inclined plane.
  • the blanks 10 are in Area of the conveyor track 11 with a small distance from each other transported.
  • an endless conveyor namely a Belt conveyor 12 is provided above the path of movement of the Blanks 10 is stored.
  • the blanks 10 are through a lower strand 13 is preferably continuously conveyed.
  • the belt conveyor 12 are for this purpose at regular intervals mutually arranged, projecting drivers 14 attached, each a blank 10 on one in the conveying direction capture rear edge.
  • the blanks 10 are in the area of the conveyor track 11 on one stationary monitoring body 15 moved past. This can do that serve, any errors in the design of the blanks 10 determine and if necessary an error signal to create.
  • the monitoring member 15 can also be the correct one Distance of the blanks 10 or the presence of an uninterrupted Determine row of blanks 10.
  • the monitoring member 15 is laterally in the longitudinal center of the Conveyor track 11 positioned stationary. It consists of two sensors 16 and 17, on opposite sides of the trajectory the blanks 10 are positioned, namely above and below the same. One of the sensors is as a transmitter and the others trained as receivers. Between the sensors 16, 17 runs a test beam, namely a light beam that temporarily is interrupted by the blanks 10. The blanks 10 for this purpose are checked with the (edge) Area conveyed between the sensors 16, 17.
  • the conveyor track 11 consists of a continuous, plate-shaped Underpass 18.
  • the spread blanks 10 lie on conveying surfaces 19 and 20 of the underpass 18. In the middle runs in the conveying direction a groove-like recess 21 for the Entry of the driver 14 of the belt conveyor 12.
  • the spread Blanks 10 cover the recess 21.
  • the conveyor track 11 are also top guides for the blanks 10 assigned. These are effective in the edge areas of the blanks 10.
  • On one side of the conveyor track 11 is an upper guide 22 arranged as a horizontal leg of the underpass 18 is formed and connected to this. Between underpass 18 and top guide 22 is created in the conveying direction Guide gap 23 for the blanks 10.
  • the monitoring member 15 is in a recess 25 of the conveyor track 11 positioned, namely the underpass 18 and the upper guide 22.
  • the monitoring member 15 consists of a housing 26. This is here fork-shaped, namely with an upper Leg 27 and a lower leg 28. The one to be monitored The area of the blanks 10 is between the two legs 27, 28 conveyed through.
  • the upper sensor 16 lies in one downward sensor surface 29 of the upper leg 27.
  • the lower sensor 17 is opposite in the area of a lower, horizontal sensor surface 30 positioned.
  • the sensors 16, 17 are via lines 31 and 32 within the Housing 26 connected with a cable 33 or open into this Electric wire.
  • the cable 33 emerges from the housing 26 and leads to a source for the test beam, in particular a light source, on the one hand and to an (optoelectronic) evaluation device (not shown) on the other hand.
  • lines 31, 32 are preferably glass fiber strands, namely made of (real) glass. These flow into the area of the sensor surfaces 29, 30. Form the ends of the glass fiber strands (lines 31, 32) directly the sensors 16, 17, i.e. transmitter and receiver for the light beam.
  • At least one of the sensors 16, 17 is positioned with respect to this on the trajectory of the blanks 10 that they are in contact over the relevant, in this case lower sensor 17 are moved away. Through this rubbing touch of the Blanks 10 with the sensor 17 is a constant, effective Cleaning the sensor 11 or keeping it free of dust and other deposits guaranteed.
  • the sensor 17 Adequate, light pressing force of the blanks 10 the sensor 17 can be reached in various ways. It is sufficient if the blanks 10 are substantially below Dead weight, possibly with a slight deflection the plane of the trajectory, slide over the sensor 17. In the present embodiment this is for this purpose the lower sensor surface 30 as an increase in the area of the movement path the blanks 10 are formed. As shown, that is Sensor surface 30 compared to that specified by the underpass 18 Path of movement of the blanks 10 increased and as arched Surface trained. The sensor 17 is at the highest Location of the (arc-shaped) sensor surface 30.
  • the housing 26 consists of rigid material, especially of metal. Are inside the housing 26 Cavities formed in which the organs and lines of one Monitoring member 15 arranged and by means of investment are fixed. The monitoring member 15 is accordingly in the Cavities first with the organs and lines for the Implementation of monitoring equipped. After that, the remaining ones Open spaces with an originally flowable, hardening Mass filled, especially with synthetic resin.
  • an upper chamber 34 and in the lower leg 28 a lower chamber 35 is formed.
  • the chambers 34 and 35 are through an upright channel 36 in a web 37 of the U-shaped Housing 26 connected together.
  • a lower one Base 38 is an outlet duct adjoining the interior 39 provided.
  • holes 40, 41 which in Area of the sensor surface 29, 30 open. These holes 40, 41 serve for the passage of lines 31, 32 or for arrangement of the sensors 16, 17. runs inside the housing 26 the upper conduit 31 in the upper chamber 34 and upright Channel 36 to the outlet channel 39, namely to the cable 33.
  • the lower line 32 leads from the sensor surface 30 via the Chamber 35 for cable 33.
  • the housing is for filling the investment material into the cavities 26 provide covers at the top and bottom in the area of the cavities, especially with plastic or metal cover plates, which are pressed onto the investment material before curing and so be connected to this.
  • the monitoring member 15 or the housing 26 is in the present Trap attached to the conveyor track 11 with a fastening element, with a fastening bolt 42, which by a laterally offset opening 43 in the web 37 of the housing 26 passes through.
  • the fastening bolt 42 connects the monitoring element with an upright support leg 44 of the underpass 18th
