Definitions

  • the invention relates to a work station, in particular a deep-drawing station, forming station, sealing station, cutting station or punching station, for a packaging machine, with a frame supported on the floor, a working unit comprising an upper part and a lower part, and a lifting mechanism carried by the frame with which the lower part the working unit can be raised and lowered relative to the frame to perform a lower stroke, the lifting mechanism having a drive which has at least one shaft extending in the transverse direction, a drive motor engaging the shaft for rotating the shaft and at least one input side coupled to the shaft Gearbox includes, on which the output side the lower part is supported and which converts a rotation of the shaft into the lower stroke of the lower part.
  • Such work stations are known in principle and are used in particular on packaging machines on which the packaging is produced from film webs.
  • depressions are produced in a lower film in a deep-drawing or molding process, then objects to be packaged, such as food products, are inserted into the depressions, then the depressions are closed by sealing with an upper film, and the individual packs are then separated by cutting or punching out.
  • a deep-drawing station for example, has a working chamber formed from an upper chamber part and a lower chamber part which the film web can be conveyed through in the open state and in which the mentioned depressions are produced in the closed state by applying negative pressure to the film web from the lower chamber and pressurized air via the upper chamber.
  • the two chamber parts must be pressed together.
  • high additional forces act on the chamber parts during the deep-drawing process due to the application of pressure on a relatively large area.
  • the lifting mechanism provided for opening and closing the chamber, the frame carrying the lifting mechanism and the devices for supporting the lifting mechanism on the frame are exposed in practice to considerable loads which can correspond to a weight of several tons.
  • the object of the invention is to create a work station of the type mentioned at the outset which, while having a simple and space-saving construction, has a powerful and highly resilient lifting mechanism.
  • the shaft of the lifting mechanism is supported on the frame and carries a base on which the upper part is supported.
  • This concept makes it possible in an advantageous manner to absorb the forces occurring during the work process, for example when closing the chamber of a deep-drawing station, within the lifting mechanism without influencing the frame.
  • the support of the lifting mechanism on the frame therefore only needs to introduce the weight of the lifting mechanism into the frame, but not the process forces acting within the lifting mechanism when the lower stroke is performed and when the lower part is raised, i.e. in a deep-drawing station with the working chamber closed.
  • the lifting mechanism consequently forms a mechanically independent and self-contained unit in terms of functionality and in terms of the process forces effective in operation, which only needs to be carried by the frame of the work station.
  • the base which is carried by the shaft supported on the frame, can comprise a frame.
  • a frame which for example has a rectangular box structure with two longitudinal members and two cross members, can ensure a particularly high stability of the lifting mechanism.
  • the interior of this stability frame is available in particular for moving parts of the lifting mechanism.
  • the gear provided between the shaft and the lower part is preferably designed as a coupling gear, in particular as a slider-crank gear. It is preferably a central sliding crank mechanism.
  • the transmission between the shaft and the lower part can comprise a toggle lever arrangement.
  • the toggle lever arrangement is stretched in a position with the lower part raised to the maximum, which corresponds in particular to a closed working unit. This ensures that at maximum Load by the process forces from the lower part no torque is exerted on the shaft.
  • This position of the transmission is also referred to below as the extended position or the neutral position.
  • the transmission between the shaft and the lower part can comprise at least one pair of congruent and spaced-apart push rods, between which a shaft crank connected in a rotationally fixed manner to the shaft and the lower part or a carrier for the lower part is hinged on the output side.
  • Such a symmetrical structure prevents the occurrence of disruptive tilting moments. Measures for absorbing or storing or transferring corresponding transverse forces can thus be dispensed with.
  • the shaft is preferably rotatably mounted in longitudinal members of the base which are spaced apart from one another in the transverse direction.
  • the shaft can carry the base in a particularly simple constructive manner and also increase the stability of the base due to the cross connection formed by the shaft between the longitudinal members.
  • the transmission preferably comprises at least two individual transmissions which are spaced apart along the shaft and synchronized by means of the shaft for joint execution of the lower stroke.
  • a shaft can act on the lower part via a gear at a plurality of points spaced apart in the transverse direction. This further increases the stability and ensures that the process forces that are effective in operation are distributed.
  • the lifting mechanism preferably comprises a plurality of synchronized shafts that are spaced apart along the frame, each with a gear for joint execution of the lower stroke.
  • Several waves in turn increase the stability of the lifting mechanism, since they are located at points on the lower part that are spaced apart in the longitudinal direction can be attacked.
  • the number of shafts can in principle be selected as desired, in particular to adapt the lifting mechanism to the length of the workstation required in each case.
  • a plurality of shafts are particularly advantageous in combination with the embodiment explained above, according to which the relevant transmission on each shaft is divided into at least two individual transmissions spaced along the shaft.
  • two synchronized individual gears are provided per shaft, which are arranged in the area of the outer sides of the lifting mechanism, i.e. a respective shaft engages the lower part with a - e.g. seen in the conveying direction of a film web running through the work station - left individual gear and a right individual gear.
  • the space between the two individual gears can then be used for other purposes.
  • a particularly precise sequence of movements of the lower part relative to the upper part can in particular be achieved in that, according to a further embodiment, the lower part is guided on the base, on the upper part or on a column supporting the upper part on the base during the lower stroke.
  • the column stands directly above the shaft, i.e. the column is supported on the base such that a vertical central axis of the column intersects the axis of rotation of the shaft.
  • a left and a right column can be provided for a respective shaft, so that the upper part is supported in the area of this shaft at two transversely spaced locations on the base and thus on the shaft carrying the base.
  • the upper part can be supported on the base in a height-adjustable manner. In this way, the position of the upper part can be adjusted relative to a film plane, for example, i.e. to the plane defined by a film web running through the work station and thus external, i.e. is determined not by the work station, but by the packaging machine in which the work station is integrated.
  • a film plane for example, i.e. to the plane defined by a film web running through the work station and thus external, i.e. is determined not by the work station, but by the packaging machine in which the work station is integrated.
  • the drive motor acts on the shaft via a coupling gear.
  • This coupling gear is not to be understood as the motor gear having the drive shaft of the motor as the input element, but a coupling gear which comprises an output element, for example a motor crank, which can be set in rotation by means of the drive motor and interacts with the shaft via the coupling gear.
  • the torque applied to a drive shaft of the drive motor via the coupling gear is zero or approximately zero.
  • the drive motor does not need to apply a holding torque when the lower part is lowered to the maximum, so that, for example, the drive motor can be exchanged without any problems in this situation.
  • the coupling gear is designed as a four-bar gear, which comprises a drive shaft of the drive motor, a motor crank connected to the drive shaft, a drive coupling articulated to the motor crank and a shaft crank connected to the shaft in a rotationally fixed manner and articulated to the drive coupling.
  • a motor transmission is provided between the drive shaft of the motor and the motor crank, which will not be discussed in detail at this point.
  • the axis of rotation of the drive shaft of the drive motor, the joint axis between the motor crank and the drive coupling and the joint axis between the drive coupling and the shaft crank are at least approximately in one plane lie.
  • This position of the linkage is also referred to below as the extended position or the neutral position.
  • the drive motor is preferably an electric motor, in particular a servo motor.
  • a pneumatic or hydraulic drive can also be provided.
  • the base can be lowered and raised relative to the frame in order to carry out an upper stroke of the upper part.

  • the workstation can be adapted in a very simple way to different applications in the operation of the packaging machine, in particular to different format sets, i.e. Arrangements of a predetermined number of packages relative to one another or to the timing of the packaging machine.
  • Adjustability of the lifting mechanism as a whole relative to the frame results in particular from the fact that the lifting mechanism represents a self-contained unit that is supported on the frame only via one or more shafts.
  • the lifting mechanism represents a self-contained unit that is supported on the frame only via one or more shafts.
  • the lifting mechanism is supported on the frame via several support elements, in particular rollers or shafts, and can be adjusted, in particular moved, in the longitudinal direction relative to the frame by means of the support elements.

  • the spindle drive can comprise a spindle attached to the frame and a spindle nut, the spindle nut preventing movement of the lifting mechanism relative to the frame in the longitudinal direction and allowing it to move in the lifting direction.
  • the spindle nut can, for example, be connected in a longitudinally displaceable manner to a column which supports the upper part on the base, in order in this way to enable an upper stroke movement of the upper part.

  • the drive motor is preferably arranged longitudinally outside of each pair of shafts. This has the advantage that the drive motor does not get in the way of the moving parts of the lifting mechanism. The space between the waves can therefore be used for other purposes.
  • the drive motor or an axis of rotation of a drive shaft of the drive motor preferably lies at least approximately in a plane defined by the axes of rotation of the shafts. Installation space above or below this plane defined by the shafts is consequently not required for the drive motor.

It is provided in particular that the drive motor engages on one of the shafts via a coupling gear and on the or every other shaft via the synchronization coupling coupled to the coupling gear. If more than two shafts are provided, either a single synchronization coupling connecting all shafts to one another can be provided. Alternatively, several synchronization couplings connected in series can be provided. This has the advantage that the synchronization coupling can act on the shafts at different transverse positions. This allows the construction of the lifting mechanism to be made more flexible.

  • the lower stroke movement of the lower part 15 and the upper stroke movement of the upper part 13 are forcibly coupled to one another via the shafts 17 and run in opposite directions, ie raising the lower part 15 is associated with lowering the upper part 13, and vice versa.
  • the shafts 17 are synchronized with one another via a synchronization coupling 43, which engages the shafts 17 via a shaft crank 25 which is connected to the respective shaft 17 in a rotationally fixed manner.
  • the synchronization coupling 43 is articulated to the shaft cranks 25 so as to be pivotable about a hinge axis 81.
  • the rotation of the motor cranks 25 is converted into a movement of the two push rods 23, as a result of which the relevant longitudinal beam 16 of the lower part 15 is moved upwards.
  • each shaft 17 engages the relevant longitudinal member 16 of the lower part 15 at two points spaced apart in the transverse direction, each with an arrangement of motor crank 25 and push rods 23.
  • the motor 19 is connected via the motor crank 31 and the drive coupling 33 only to the rear shaft crank 25 in the side view selected here.
  • the four-bar gear formed by the drive shaft 29 of the motor 19, the motor crank 31, the drive coupling 33 and the shaft crank 25 is also in a neutral position in the sense of a stretched state in which the relevant axes lie in a common plane.
  • the relevant axes are the axis of rotation 65 of the drive shaft 29 of the motor 19, the joint axis 63 between the motor crank 31 and the drive coupling 33, as well as the joint axis 67 between the drive coupling 33 and the shaft crank 25.
  • This stretched state has the consequence that the shaft crank 25 can no longer rotate clockwise, the total effective weight of the lower part 15 and of the transmission consequently cannot exert any torque on the drive shaft 29 of the motor 19.
  • the motor 19 When the working chamber is open, ie when the lower part 15 is lowered to the maximum, the motor 19 is thus free from external forces.
  • the motor 19 consequently does not need to have a holding current applied to it in order to generate a torque counteracting a weight force.
  • the moving parts and their connections are optimized and arranged relative to one another in such a way that, taking into account an upper stroke movement of the upper part 13 explained in more detail below, an optimal force or torque curve without disadvantageous force or torque peaks over the entire opening or Closing movement of the working chamber, that is to say over the entire angle of rotation of the motor crank 31 or of the shafts 17, results.
  • the above-described sequence of movements of the lower stroke of the lower part 15 is independent of the manner in which the lifting mechanism is supported on the frame 11 (cf. Fig. 1 ) or on the support profiles 37 of the frame.
  • the maximum stroke of the lower part 15 relative to the shafts 17 does not correspond to the effective working stroke of the working chamber ( e.g. 80mm).
  • the reason for this is that the rotation of the shafts 17 brought about for the execution of the lower stroke of the lower part 15 simultaneously results in a lowering of the shafts 17.
  • the lowering of the shafts 17 results in a downward movement of the entire lifting mechanism including the upper part 13 supported by the columns 27 on the shafts 17 relative to the frame and thus relative to the film plane 55.
  • the lowering of the shafts 17 is achieved by eccentric mounting of the shafts 17 on the support rollers 35.
  • This concept can be particularly well illustrated by the Fig. 2a and 3a are understood, in which the support roller 35 is not shown in each case on the left gear. Instead, it can be seen there that the axes of rotation 18 of the shafts 17 do not coincide with the axes of rotation of the support rollers 35, also referred to below as eccentric axes 36.
  • the eccentricity, ie the radial distance between the axis of rotation 18 of the shaft 17 and the eccentric axis 36 determines the maximum stroke of the upper stroke at a given maximum angle of rotation of the shaft 17.
  • the eccentric axes 36 also lie in the common vertical plane of the joint axis 71, the joint axis 73 and the shaft rotation axis 18.
  • the eccentric axes 36 each lie vertically above the rotation axis 18 of the relevant shaft 17, ie the shafts 17 and thus the entire lifting mechanism, in particular including the upper part 13, are lowered to the maximum extent with respect to the frame.
  • the support rollers 35 enable the lifting mechanism to be positioned in the longitudinal direction by manually rotating the spindle 39, as has already been described above.
  • the lifting mechanism is a carriage that can be moved in the longitudinal direction on the support profiles 37 of the frame with wheels formed by the support rollers 35 arranged eccentrically with respect to the axes of rotation 18 of the shafts 17 and with a stable base formed by the frame comprising the longitudinal members 20 and the cross members 22.
  • the shafts 17 are rotatably mounted in this base and thus carry the upper part 13 via the columns 27 and the longitudinal beams 20 and the lower part 15 via the gears formed by the shaft crank 25 and the push rods 23.
  • FIGS Figure 4b , 5b and 6b While in the Figure 4a , 5a and 6a The open state with the lower part 15 lowered to the maximum and the upper part 13 raised to the maximum are shown in FIGS Figure 4b , 5b and 6b the state of the lifting mechanism with the chamber closed.
  • the carrier 16 and the cross strut 45 of the lower part 15 and the longitudinal elements 59 of the upper part 13 represent functional blocks for the lower chamber and the upper chamber (not shown) and are provided with the electrical and pneumatic connections and connections required for the operation of the working chamber.
  • Another advantage of the lifting mechanism according to the invention is that the integration of the overstroke movement does not mean any significant additional effort, but only requires the explained eccentric connection between the shafts 17 and the support rollers 35 instead of a centric connection that is basically also possible.
