Definitions

  • the invention relates to a folding device, in particular a folding turret for producing packs from at least one foldable blank, preferably cigarette soft cup packs, with circumferential supporting members (folding mandrels) mounted on one side for the blanks or packs.
  • a folding turret for producing packs from at least one foldable blank, preferably cigarette soft cup packs, with circumferential supporting members (folding mandrels) mounted on one side for the blanks or packs.
  • the one-sided protruding or projecting folding mandrels are continuously moved by a conveyor during the folding and filling process of the pack, in particular by a folding turret. Due to the arrangement (one-sided attachment) as well as the geometric shape and dimensions, the folding mandrels are sensitive to mechanical loads. Unwanted deformations of the folding mandrels during the operation of the packaging machine cannot be excluded. If the deformations exceed a certain level, there are disruptions in the packaging process. Wrong packs arise. The packaging machine must be stopped, the deformed folding mandrel identified and straightened or replaced. This process is time consuming.
  • the invention has for its object to provide a folding device of the type mentioned in such a way that an error signal is generated in the event of undesired or impermissible deformations of the folding mandrels, which facilitates the removal of the error.
  • the folding device is characterized by a stationary device (monitoring unit) assigned to the folding turret or the like for monitoring deformations of the folding mandrels or the like, the monitoring unit detecting undesirable deformations of the folding mandrels and an error signal assigned to the relevant folding mandrel generated.
  • a stationary device monitoring unit assigned to the folding turret or the like for monitoring deformations of the folding mandrels or the like
  • the monitoring unit detecting undesirable deformations of the folding mandrels and an error signal assigned to the relevant folding mandrel generated.
  • the contours or the relative position of the folding mandrels are therefore scanned without contact. Becomes Defined error signal that identifies the deformed folding mandrel.
  • the packaging machine or folding turret is stopped for a short time in order to straighten or replace the faulty folding mandrel. The tedious and time-consuming search for the faulty folding mandrel is not necessary.
  • inductive sensors of known design are used for scanning the contours or relative positions of the folding mandrels.
  • these are arranged in a fixed location at a short distance from the orbit of the folding mandrels, in such a way that changes in the folding mandrels can be detected and identified without contact.
  • two inductive buttons are arranged in succession in the direction of movement on the outer circumference of the movement path of the folding mandrels.
  • the inductive pushbuttons or their probes are arranged at different distances from the path of movement of the folding mandrels, such that when the folding mandrels are correctly designed, one of the inductive pushbuttons acts on each of the folding mandrels due to the smaller distance, while the other inductive pushbutton remains unaffected due to a correspondingly larger distance.
  • both inductive pushbuttons are acted upon by the respective folding mandrel or none of the inductive pushbuttons because the folding mandrel lies outside the effective range of both inductive pushbuttons.
  • Markings can be attached to the folding mandrels, which are scanned by the sensing elements of the monitoring device.
  • the longitudinal edges of the folding mandrels with a rectangular cross section are scanned according to the invention. According to the invention, the scanning of longitudinal edges of the folding mandrels with a rectangular cross section.
  • the sensing elements in particular inductive sensors, can also be attached to opposite sides of the orbit of the folding mandrels, that is to say radially outside and inside.
  • both inductive buttons can have the same distance from the target orbit of the folding mandrels, since deformations in one direction or the other are always detected by the inductive button provided for this purpose.
  • the inductive sensors that are preferably used are also known in the art as proximity switches. These are electronic probes that have a probe for generating an electromagnetic field. If a metallic object approaches the probe, a signal is generated as soon as the range of effectiveness (switching distance) of the proximity switch is reached. In the present exemplary embodiment, proximity switches or inductive sensors are used, the switching distance of which is 4 mm. When a (metallic) marking or a longitudinal edge of the folding mandrel selected according to the invention reaches the effective range of the inductive button, a signal is generated.
  • the exemplary embodiments shown in the drawings are concerned with the monitoring of folding members of a folding unit with regard to correct design and arrangement. Specifically, it is about a revolving folding turret 10, which is provided on the outer circumference with axially parallel folding mandrels 11. These are elongated hollow bodies made of thin-walled metallic material (sheet metal) with a rectangular cross section in the present case. The folding mandrels 11 are open at both ends. These are known and customary organs which are used above all in the manufacture of soft-cup packs for holding cigarettes. The blanks forming packs are folded on the outside of the folding mandrels 11 during the rotational movement of the folding turret 10.
  • the folding turret 10 shown as an exemplary embodiment in the present case is described in detail and shown in US Pat. No. 4,852,335.
  • the folding mandrels 11 are supported on one side on the folding turret 10, namely on a turret disk 12.
  • the relatively long hollow body of the folding mandrel 11 consists of thin-walled material and is therefore susceptible to mechanical loads. Deformations can therefore occur during operation of the packaging machine.
  • the monitoring unit 13 is located (exclusively) on the radially outer side of the folding turret 10 or a circular movement path of the folding mandrels 11. Accordingly, the outward contours of the folding mandrels 11 are monitored, and by contactless scanning. If changes in the shape or relative position of a folding mandrel 11 are determined, the monitoring unit 13 generates an error signal which is assigned to the faulty folding mandrel 11. This can be identified when the folding turret 10 is briefly stopped. The faulty folding mandrel 11 is straightened or replaced.
  • the folding mandrels 11 are marked differently, namely in particular provided with consecutive numbers.
  • a control unit to which the monitoring unit 13 is connected contains an identification disk, the position of which corresponds to the position of the folding turret 10 and thus of the folding mandrels 11. If an error signal is now triggered by a deformed folding mandrel 11, the relative position of the folding turret 10 and thus the affected folding mandrel 11 are identified at the same time via the identification disk.
  • the packaging machine is equipped with a screen on which the folding mandrels 11 are shown. The faulty folding mandrel 11 is recognized in accordance with the identification on the screen.
  • the monitoring unit 13 is equipped with contactless sensing elements, in the present case with proximity switches or inductive buttons 14 and 15.
  • the inductive buttons are of a type known per se.
  • Each inductive button 14, 15 is provided with a probe 16, 17.
  • a magnetic field is generated in its area.
  • the magnetic field has a limited effective range (switching distance). If a metallic object enters the effective range of the inductive button 14, 15 or the probe head 16, 17, a switching process is triggered by the inductive button 14, 15.
  • Inductive button 14, 15 is provided with a probe 16, 17. A magnetic field is generated in its area. The magnetic field has a limited effective range (switching distance). If a metallic object enters the effective range of the inductive button 14, 15 or the probe head 16, 17, a switching process is triggered by the inductive button 14, 15.
  • the sensing elements are arranged adjacent to the free end of the folding mandrel 11, that is to say at the greatest possible distance from the turret disk 12 carrying the folding mandrels 11.
  • the inductive buttons 14, 15 or their probe heads 16, 17 are arranged at different distances from the folding mandrels 11 and their longitudinal edges 18, 19.
  • the first inductive button 14 in the direction of movement is arranged such that a switching process is triggered each time the longitudinal edges 18, 19 of the correctly arranged folding mandrels 11 pass. The distance is therefore smaller with a switching distance of 4 mm selected here.
  • the inductive button 15 following in the direction of movement is at a distance from the longitudinal edges 18, 19 which is greater than the predetermined switching distance. Accordingly, no signal is triggered by this inductive button 15 if the folding mandrels 11 are formed correctly.
  • the monitoring unit 13 triggers an error signal.
  • an error signal in the event of undesired deformation of a folding mandrel 11 is assigned to the relevant folding mandrel 11. These are appropriately marked, e.g. numbered. It is therefore easy to identify the faulty folding mandrel when the folding turret 10 is stationary.
  • the monitoring unit 13 can be designed in various ways. However, it makes sense to accommodate the inductive buttons 14, 15 in a largely closed housing 22. This is supported on the machine frame via a support arm 23.
  • the largely closed housing 22 is provided in the region of a housing wall 24 facing the folding mandrels 11 with an opening 25 for the passage of the inductive button 14, 15 or the probe head 16, 17.
  • a special holder for the inductive buttons 14, 15 is provided within the housing 22. It is a spring element, in the present case a leaf spring 26, which is fixed in the housing 22 under a certain preload
  • An electrical line 28 is connected to each inductive button 14, 15, on the one hand for the power supply and on the other hand for switching lines.
  • FIGS. 4 and 5 show an alternative with regard to the design of the monitoring unit 13.
  • (two) inductive sensors 29, 30 are arranged on opposite sides of the orbit of the folding mandrels 11. This makes the switching process easier.
  • the inductive buttons 29, 30 can have the same distance from the path of movement of the (correct) folding mandrels 11. This distance can either be in the range of the switching distance or outside of it. Deformations in one direction or the other lead to a change in the switching behavior of at least one inductive button 29, 30.
  • all four longitudinal edges 18, 21 are effective for monitoring the position or shape of the folding mandrel 11.
  • the inductive buttons 29, 30 are accommodated in a U-shaped housing 31, in each case in one leg 32 or 33 of the same.
  • the mounting of the inductive buttons 29, 30 corresponds to the exemplary embodiment according to FIGS. 2 and 3.
  • the monitoring unit 13 is not switched on continuously, but is controlled so that only the longitudinal edges 18, 19 and 20, 21 of the folding mandrels 11 are scanned.
  • the inductive buttons 14, 15 and 29, 30 are supplied with current. edges 18, 19 and 20, 21 of the folding mandrels 11 are scanned.
  • the inductive buttons 14, 15 and 29, 30 are supplied with current.
