Definitions

  • the invention relates to a workstation, in particular a thermoforming station, forming station, sealing station, cutting station or punching station, for a packaging machine, comprising a base supported on the base, a working unit comprising a top and a bottom, and a lifting mechanism carried by the frame, with which the lower part of the working unit can be raised and lowered relative to the frame for carrying out a sub-stroke, the lifting mechanism having a drive comprising at least one transversely extending shaft, a drive motor acting on the shaft for rotating the shaft and at least one input side Gear coupled to the shaft comprises, on the output side, the lower part is supported and converts a rotation of the shaft in the lower stroke of the lower part.
  • Such workstations are basically known and are used, in particular, on such packaging machines on which the packages are produced from film webs. Recesses are first prepared in a lower film in a thermoforming or molding process, then inserted into the wells to be packaged items such as food products, then closed the wells by sealing with a top film, and then isolated the individual packages by cutting or punching. At least at some workstations of the packaging machine, it is necessary to raise and lower the tools used for the respective work process.
  • thermoforming station has a working chamber formed by an upper chamber part and a lower chamber part which in the opened state, the film web can be conveyed through and in which in the closed state, the recesses mentioned are prepared by the film web from the lower chamber with negative pressure and the upper chamber is pressurized with compressed air.
  • the two chamber parts must be pressed together.
  • act on the chamber parts during the deep drawing process due to the pressurization on a relatively large area high additional forces. Consequently, in practice, the lifting mechanism provided for opening and closing the chamber, the frame carrying the lifting mechanism and the means for supporting the lifting mechanism on the frame are subjected to considerable loads which may correspond to a weight force of several tons.
  • Known workstations for packaging machines are described, for example, in EP 1 1 18 540 B1, DE 103 51 567 B4, DE 10 2004 006 1 18 A1, DE 10 2008 019 626 A1, DE 10 2015 21 2122 A1 and EP 2 666 727 B1.
  • the object of the invention is to provide a workstation of the type mentioned, which has a powerful and highly resilient lifting mechanism with a simple and space-saving design.
  • 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 advantageously to absorb the forces occurring during the working process, for example when closing the chamber of a thermoforming station, within the lifting mechanism without influencing the frame.
  • the support of the lifting mechanism on the frame therefore only needs to initiate the weight of the lifting mechanism in the frame, but not during the execution of the lower stroke and during the raised lower part, ie in a thermoforming station with closed working chamber, acting within the lifting process forces.
  • the lifting mechanism consequently forms a mechanically independent and self-contained unit that is functional and operative with respect to the process forces effective in operation, and which only needs to be carried by the workstation frame.
  • the base carried by the shaft supported on the frame may comprise a frame.
  • a frame for example, has a rectangular box body with two side rails 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 provided between the shaft and lower part gearbox is preferably designed as a coupling gear, in particular as a sliding crank gear.
  • a coupling gear in particular as a sliding crank gear.
  • it is a centric slider crank mechanism.
  • the transmission between the shaft and lower part may comprise a toggle lever arrangement.
  • the toggle lever assembly is stretched in a position with a maximum raised lower part, which corresponds in particular to a closed working unit. This can ensure that at maximum Load from the process forces from the base no torque is exerted on the shaft.
  • This position of the transmission is also referred to below as the extended position or neutral position.
  • the transmission between the shaft and lower part may comprise at least a pair of congruent and spaced push rods, between which the input side a rotatably connected to the shaft shaft crank and the output side, the lower part or a support for the lower part is articulated.
  • Such a symmetrical construction prevents the occurrence of disturbing overturning moments. Measures for receiving or storage or derivation of corresponding shear forces can thus be omitted.
  • the shaft is preferably rotatably mounted in longitudinally spaced-apart longitudinal supports of the base.
  • the shaft can support the base in a particularly simple constructive manner and also increase the stability of the base due to the transverse connection formed between the longitudinal members by the shaft.
  • the transmission comprises at least two spaced apart along the shaft and synchronized by means of the shaft single transmission for common execution of the sub-hub. Consequently, a shaft can engage at a plurality of transversely spaced locations via a gear on the base. This further increases the stability and ensures a distribution of the effective process forces during operation.
  • the lifting mechanism comprises a plurality of spaced along the frame and synchronized shafts, each with a transmission for common execution of the sub-hub.
  • multiple shafts increase the stability of the lifting mechanism, as at longitudinally spaced locations on the base can be attacked.
  • the number of waves can basically be chosen arbitrarily, in particular to adapt the lifting mechanism to the particular required length of the workstation. Several waves are particularly advantageous in combination with the previously described embodiment, according to which the respective transmission is divided into at least two individual gears spaced along the shaft on each shaft.
  • two synchronized individual gears are provided per shaft, which are arranged in the region of the outer sides of the lifting mechanism, i. a respective shaft engages the base with a - e.g. seen in the conveying direction of a running through the work station film web - left single gear and a right single gear.
  • the space between the two single gears can then be used elsewhere.
  • a particularly precise movement sequence of the lower part relative to the upper part can be achieved in particular by the lower part being guided during the lower stroke at the base, at the upper part or at a pillar supporting the upper part at the base.
  • the column is directly above the shaft, i. the column is supported on the base such that a vertical center axis of the column intersects the axis of rotation of the shaft.
  • a left and a right pillar may be provided in a respective shaft, so that the upper part is supported in the region of this shaft at two transversely spaced locations on the base and thus on the shaft supporting the base.
  • the arrangement of columns directly over the waves provides advantageously for a direct derivation of the weight of the upper part in the shaft and thus in the frame.
  • the upper part can be supported height-adjustable at the base. In this way, the position of the upper part, for example, be adjusted relative to a film plane, ie to the plane which is defined by a running through the work station film web and thus externally, that is not determined by the workstation, but by the packaging machine, in which the workstation is integrated.
  • the drive motor engages the shaft via a coupling gear.
  • this coupling gear is not to be understood as the input member, the drive shaft of the motor having motor gear, but a coupling gear which comprises a rotatable by means of the drive motor and cooperating via the coupling gear with the shaft output member, such as a motor crank.
  • the coupling gear is designed as a four-bar linkage comprising a drive shaft of the drive motor, an engine crank connected to the drive shaft, a drive link articulated to the engine crank, and a shaft crank pivotally connected to the shaft and pivotally connected to the drive link.
  • the drive motor is preferably an electric motor, in particular a servomotor. It may alternatively be provided a pneumatic or hydraulic drive.
  • the base for executing an upper stroke of the upper part can be lowered and raised relative to the frame.
  • the lifting mechanism can be provided with an integrated upper lift function. On possible embodiments of the lifting mechanism for the realization of this Oberhub function will be discussed in more detail elsewhere.
  • the sub-stroke and the upper stroke are positively coupled together.
  • the sub-stroke movement and the upper stroke movement can assist each other in an advantageous manner.
  • this forced coupling takes place through the shaft.
  • sub-stroke and the upper stroke run in opposite directions to each other.
  • the lifting mechanism is adjustable in the longitudinal direction relative to the frame.
  • the workstation can be adapted in a very simple manner to different applications during operation of the packaging machine, in particular to different formats, ie arrangements of a predetermined number of packages relative to one another, or to the timing of the packaging machine.
  • An adjustability of the lifting mechanism as a whole relative to the frame results in particular from the fact that the lifting mechanism is a self-contained unit which is supported only on one or more waves on the frame.
  • the lifting mechanism in the manner of a carriage or carriage, which can be displaced or moved as a whole on the frame be brought into the respective desired position within the workstation and consequently within the respective packaging machine.
  • the lifting mechanism is supported on the frame via a plurality of support members, in particular rollers or shafts, and is adjustable, in particular movable, by means of the support members in the longitudinal direction relative to the frame.
  • the frame can have at least two carrier profiles running parallel to one another in the longitudinal direction, on which the lifting mechanism is supported and along which the lifting mechanism is adjustable relative to the frame.
  • lifting mechanism and frame can cooperate in terms of adjustability in the longitudinal direction as a wheel / rail system.
  • preferably designed as rollers support members may each be provided with a recess or a step.
  • a fixing device may be provided, by means of which the position of the lifting mechanism can be fixed in the longitudinal direction on the frame.
  • the fixing device may comprise a spindle drive for adjusting the longitudinal position of the lifting mechanism.
  • the spindle drive may comprise a frame-mounted spindle and a spindle nut, wherein the spindle nut prevents movement of the lifting mechanism relative to the frame in the longitudinal direction and permits in the stroke direction.
  • the spindle nut may, for example, be longitudinally displaceably connected to a pillar supporting the upper part at the base in order to allow in this way an upper stroke movement of the upper part.
  • the lifting mechanism comprises a plurality of shafts spaced and synchronized along the frame, each having a gear for common execution of the sub-stroke. By providing a plurality of shafts, the lifting mechanism can engage at longitudinally spaced locations on the base. This increases the stability and ensures a precise alignment of the lower part relative to the upper part.
  • exactly one drive motor is provided for synchronously rotating the shafts. This simplifies the construction of the lifting mechanism and reduces costs.
  • the drive motor is preferably arranged longitudinally outside each pair of shafts. This has the advantage that the drive motor is not in the way of the moving parts of the lifting mechanism. The space between the waves can therefore be used elsewhere.
  • the drive motor or an axis of rotation of a drive shaft of the drive motor is at least approximately in a plane defined by the axes of rotation of the waves. Space above or below this defined by the waves level is therefore not required for the drive motor.
  • the shafts are supported on the frame and together carry a base, preferably comprising a frame, on which the upper part is supported, the drive motor being arranged outside the base.
  • the arrangement of the drive motor outside the base, the interior of the base is otherwise available, for example, for electrical, pneumatic or hydraulic lines in connection with the function of the tool used in the workstation.
  • the moving parts of the Lifting mechanism and its kinematics of the drive motor itself not to be considered.
  • the drive motor is supported on a cross member of the base.
  • the drive motor is arranged such that a drive shaft of the drive motor runs parallel to the waves. This facilitates the coupling between the drive motor and shaft. In particular, can be dispensed with an angle gear for the drive motor.
  • the waves are mechanically synchronized.
  • the waves are rotatable in the same direction. This allows a particularly simple structure and a space-saving arrangement of the moving parts for synchronous rotation of the shafts.
  • the waves are interconnected by at least one synchronization coupling.
  • the drive motor to act on one of the shafts via a coupling gear and on the or each other shaft via the synchronization coupling coupled to the coupling gear.
  • a coupling gear can be provided in order to act on one of the shafts via a coupling gear and on the or each other shaft via the synchronization coupling coupled to the coupling gear.
  • a plurality of synchronizing couplers connected in series can be provided. This has the advantage that the synchronization coupling can attack at different transverse positions on the waves. As a result, the structure of the lifting mechanism can be made more flexible.
  • the synchronization coupling acts on the shafts in each case via a shaft crank connected in a rotationally fixed manner to the shaft.
  • the drive motor acts on the shaft via a gear.
  • this transmission can be tuned to the transmission between the shaft and the lower part with regard to the respective conditions. This applies not only to the situations explained in more detail below with the lower part maximally raised and the lower part maximally lowered, but also the course of motion and the progression of forces or torques in the execution of the lifting movement between the two mentioned extreme positions.
  • the structure of the gearbox and the arrangement of the moving parts within the lifting mechanism and thus within the workstation on the one hand and the torque curve on the other hand vote so that a relatively small drive motor with comparatively low power is sufficient to carry out the respectively required lifting movement, and the moving parts of the lifting mechanism require little space.
  • the transmission between the lower part and the shaft and the transmission between the drive motor and the shaft are designed and matched to each other, that at maximum lifted Lower part and at maximum lowered lower part each one of the transmission assumes a neutral position.
  • the torque applied from the lower part to the shaft is zero or approximately zero. This can be achieved for example by a stretched in this position toggle assembly of the transmission between the shaft and lower part.
  • the torque applied from the lower part to a drive shaft of the drive motor is zero or approximately zero when the lower part is maximally lowered.
  • this can be achieved, for example, by an extended configuration of a four-bar transmission forming the transmission between the drive motor and the shaft.
  • a common element and in particular as a single common element of the two gear can be provided rotatably connected to the shaft shaft crank.
  • a preferred embodiment provides that upon execution of the maximum stroke of the lower part, an engine crank connected to the drive motor rotates at a larger angle than the shaft.
  • the angle of rotation of the motor crank by about 20 to 70%, in particular by about 40 to 60%, be greater than the angle of rotation of the shaft.
  • the maximum stroke of the lower part corresponds to a rotation of the shaft by about 80 ° to 120 °, in particular by about 100 °. Furthermore, it can be provided that the maximum stroke of the lower part corresponds to a rotation of an engine crank connected to the drive motor by approximately 140 ° to 160 °, in particular by approximately 150 °. According to a further independent aspect of the invention, it is provided that the upper part can be lowered and raised relative to the frame for carrying out an upper stroke.
  • a particularly advantageous possibility for carrying out an upper stroke arises in a structure of the lifting mechanism and in a manner of supporting the lifting mechanism on the frame, as has been explained above in connection with one of the other independent aspects of the invention.
  • the ability to perform a top lift is not mandatory in such a concept, but can be implemented in a simple manner to integrate a lift function in the lift mechanism.
  • the upper part is preferably supported on the frame via the lifting mechanism.
  • the upper part is supported on the frame via the shaft.
  • a preferred way of integrating an upper lift function into the lift mechanism provides that the shaft is mounted eccentrically with respect to its axis of rotation on the frame. Rotation of the shaft about its axis of rotation thus results in movement of the axis of rotation relative to the frame with a vertical component. This movement of the shaft can be used to perform a top lift movement of the upper part. Consequently, according to the invention, a lifting mechanism can be converted into a lifting mechanism with a lifting function with a centric bearing of the shaft in an eccentric bearing with a shaft mounted on the shaft and without a top lift function.
  • the eccentricity of the eccentric bearing of the shaft is changed.
  • the upper part is supported on a base, preferably comprising a frame, of the lifting mechanism, wherein the shaft is rotatably mounted in the base.
  • the shaft is mounted and rotated eccentrically with respect to its axis of rotation, the resulting vertical movement of the shaft is transferred to the base and thus to the upper part.
  • At least two spaced along the shaft support members may be provided, on which the shaft is mounted eccentrically in each case with respect to its longitudinal axis. Upon rotation of the shaft, the shaft thus moves relative to the support members in the vertical direction, to perform in this way the Oberhub function.
  • the support members are capable of evasive movement in the longitudinal direction.
  • the support members each comprise a roller or a roller. While in this way a rotation of the shaft not only causes the raising and lowering of the base, but also results in a vertical movement of the shaft, which can be converted into an upward or downward movement of the upper part, this means that the lower stroke of the lower part and the upper stroke of the upper part are forcibly coupled together via a rotation of the shaft.
  • the sub-stroke and the upper stroke run in opposite directions to each other.
  • the two strokes can thus support each other, whereby the maximum of the drive motor to be applied power can be significantly reduced.
  • the effective working stroke of the working unit given by the difference between the sub-stroke and the top stroke is approximately 75 to 85 mm, preferably approximately 80 mm.
  • the maximum amount of the upper stroke is about 0.2 times to 0.3 times the maximum amount of the sub-stroke.

  • the motor 19 rotates the motor crank 31 by about 150 ° counterclockwise, whereby all the crankshaft 25 rotate synchronously with the shafts 17 also counterclockwise, by a rotation angle of about 100 °. Between the engine crank 31 and the shafts 17 is thus given a reduction.

  • the four-bar linkage formed by the drive shaft 29 of the motor 19, the motor crank 31, the drive coupling 33 and the crankshaft 25 is likewise in a neutral position in the sense of an extended 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 hinge axis 63 between the engine crank 31 and the drive coupling 33, and the hinge axis 67 between the drive coupling 33 and the shaft crank 25.

  • the lowering of the shafts 17 is achieved by an eccentric mounting of the shafts 17 on the support rollers 35. This concept can be particularly well understood with reference to FIGS. 2a and 3a, in which the support roller 35 is not shown in each case on the left transmission. Instead, it can be seen there that the axes of rotation 18 of the shafts 17 do not coincide with the rotational axes of the support rollers 35, which are 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 - for a given maximum rotation angle of the shaft 17 - the maximum stroke of the upper stroke.

  • the illustrations in FIGS. 6a and 6b show, in particular, the symmetrical structure of the individual transmissions, in each of which the carrier 16 of the lower part 15 and the shaft crank 25 are arranged between the pair of push rods 23. This simplifies the design of the pivot bearings between the push rods 23 and the carrier 16 on the one hand and the push rods 23 and the shaft crank 25 on the other hand, since tilting moments and resulting lateral forces are avoided or at least minimized.
  • the guide tabs 61 for vertical guidance of the lower part 15 on the columns 27 can consequently be made comparatively simple. This also underlines the extremely robust and low-maintenance overall structure of the lifting mechanism.
  • Another advantage of the lifting mechanism according to the invention is that the integration of the upper stroke movement means no significant additional effort, but only the explained eccentric instead of a basically also possible centric connection between the shafts 17 and the support rollers 35 requires.
