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 work 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 carry out a sub-stroke, the lifting mechanism having a drive which has at least one shaft extending in the transverse direction, a drive motor acting on the shaft for rotating the shaft and at least one coupled to the shaft on the input side Gear includes, on which the lower part is supported on the output side and which converts a rotation of the shaft into the lower stroke of the lower part.
  • Such work stations are generally known and are used in particular on packaging machines where the packaging is made from film webs.
  • depressions are first made in a bottom 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 a top film, and then the individual packs are 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 in the open state the film web can be conveyed through and in which in the closed state the mentioned depressions are produced by applying negative pressure to the film web from the lower chamber and with compressed 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 pressurization on a relatively large area. Consequently, 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 in practice exposed 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 beginning, which has a powerful and highly resilient lifting mechanism with a simple and space-saving structure.
  • the shaft of the lifting mechanism is supported on the frame and carries a base on which the upper part is supported.
  • This concept advantageously makes it possible to absorb the forces that occur 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 executing the lower stroke and during the lifting of the lower part, in a deep-drawing station, i.e. with the working chamber closed.
  • the lifting mechanism therefore forms a mechanically independent and self-contained unit in terms of functionality and with regard to the process forces effective during operation, which only needs to be carried by the frame of the work station.
  • the base which is supported by the shaft supported on the frame, may comprise a frame.
  • a frame which has, for example, a rectangular box structure with two longitudinal beams and two cross beams, can ensure a particularly high stability of the lifting mechanism.
  • the interior of this stability frame is particularly available 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 centric slider crank mechanism.
  • the gear between the shaft and the lower part can include 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 work unit. This can ensure that at maximum No torque is exerted on the shaft due to the process forces from the lower part.
  • This position of the transmission is also referred to below as the extended position or the neutral position.
  • the gear 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 is articulated on the input side and the lower part or a carrier for the lower part is articulated on the output side.
  • Such a symmetrical structure prevents the creation of disruptive tilting moments. Measures to absorb or store or dissipate corresponding transverse forces can therefore be omitted.
  • the shaft is rotatably mounted in longitudinal supports of the base that are spaced apart from one another in the transverse direction.
  • the shaft can support the base in a particularly simple structural manner and can also increase the stability of the base due to the cross connection between the longitudinal beams formed by the shaft.
  • the transmission preferably comprises at least two individual transmissions spaced apart along the shaft and synchronized by means of the shaft for joint execution of the lower stroke. Consequently, a shaft can engage the lower part via a gear at several points spaced apart in the transverse direction. This further increases stability and ensures that the process forces effective during operation are distributed.
  • the lifting mechanism preferably comprises a plurality of synchronized shafts spaced apart along the frame, each with a gear for carrying out the lower stroke together.
  • Several shafts in turn increase the stability of the lifting mechanism, as 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 basically be chosen arbitrarily, in particular to adapt the lifting mechanism to the required overall length of the work station.
  • gear in question is divided into at least two individual gears spaced apart along the shaft on each 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. each shaft engages on the lower part with a left-hand individual gear and a right-hand individual gear - seen, for example, in the conveying direction of a film web running through the work station.
  • the space between the two individual gears can then be used for other purposes.
  • a particularly precise movement sequence of the lower part relative to the upper part can be achieved in particular 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 in such a way 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 in the area of this shaft is supported at two points spaced apart in the transverse direction on the base and thus on the shaft carrying the base.
  • the upper part can be supported on the base in an adjustable height.
  • the position of the upper part can be adjusted, for example, relative to a film plane, i.e. to the plane which is defined by a film web running through the work station and is therefore determined externally, i.e. not by the work station, but by the packaging machine into which the work station is located is integrated.
  • the drive motor engages the shaft via a coupling gear.
  • This coupling gear is not to be understood as meaning the motor gear having the drive shaft of the motor as an input member, but rather a coupling gear that includes an output member, 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 any holding torque when the lower part is lowered to the maximum, so that, for example, the drive motor can be easily replaced in this situation.
  • the coupling gear is designed as a four-bar linkage, 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 in a rotationally fixed manner to the shaft and articulated to the drive coupling.
  • a motor gear is provided between the drive shaft of the motor and the motor crank, which will not be discussed in more detail here.
  • 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 lay.
  • This position of the coupling gear 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.
  • This allows the lifting mechanism to be provided with an integrated upper lift function. Possible configurations of the lifting mechanism to implement this upper lift function will be discussed in more detail elsewhere.
  • the lower stroke and the upper stroke are positively coupled to one another.
  • the lower stroke movement and the upper stroke movement can advantageously support each other.
  • This forced coupling preferably takes place through the shaft.
  • the lower stroke and the upper stroke run in opposite directions to one another.
  • the lifting mechanism is adjustable in the longitudinal direction relative to the frame.
  • the work station can be adapted in a very simple manner 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.
  • An 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 only supported on the frame via one or more shafts.
  • 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, in the longitudinal direction relative to the frame by means of the support members.
  • the frame can have at least two support profiles running parallel and spaced apart in the longitudinal direction, on which the lifting mechanism is supported and along which the lifting mechanism is adjustable relative to the frame.
  • the lifting mechanism and frame can work together as a wheel/rail system with regard to adjustability in the longitudinal direction.
  • the support members which are preferably designed as rollers, can each be provided with a recess or a step.
  • a fixing device can be provided, by means of which the position of the lifting mechanism in the longitudinal direction on the frame can be fixed.
  • the fixing device can include a spindle drive for adjusting the longitudinal position of the lifting mechanism.
  • 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 in the lifting direction.
  • the spindle nut can, for example, be connected in a longitudinally displaceable manner to a column supporting the upper part on the base in order to enable an upper stroke movement of the upper part.
  • the lifting mechanism comprises a plurality of synchronized shafts spaced apart along the frame, each with a gear for jointly carrying out the lower stroke.
  • the lifting mechanism can act on the lower part at points spaced apart in the longitudinal direction. This increases stability and ensures precise alignment of the lower part relative to the upper part.
  • exactly one drive motor is provided for synchronous rotation of 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 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 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 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 drive motor being arranged outside the base.
  • the interior of the base is available for other purposes, for example for electrical, pneumatic or hydraulic lines in connection with the function of the tool used in the work station.
  • the moving parts of the Lifting mechanism and its kinematics of the drive motor itself are not taken into account.
  • the drive motor is preferably 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 shafts. This facilitates the coupling between the drive motor and the shaft.
  • an angular gear for the drive motor can be dispensed with.
  • the waves are mechanically synchronized.
  • the shafts are preferably rotatable in the same direction. This enables a particularly simple structure and a space-saving arrangement of the moving parts for synchronous rotation of the shafts.
  • the shafts are connected to one another by at least one synchronization coupling.
  • the drive motor acts on one of the shafts via a coupling gear and on the or any other shaft via the synchronization coupling coupled to the coupling gear. If more than two waves are provided, either a single synchronization coupling that connects all waves to one another can be provided. Alternatively, several synchronization couplings connected in series can be provided. This has the advantage that the synchronization couplings can act on the shafts at different transverse positions. This allows the structure of the lifting mechanism to be made more flexible.
  • the synchronization coupling engages the shafts via a shaft crank connected to the shaft in a rotationally fixed manner.
  • the drive motor engages the shaft via a gear.
  • this gear can be coordinated with the gear between the shaft and the lower part with regard to the respective circumstances. This not only affects the situations explained in more detail below with the lower part raised to the maximum and the lower part lowered to the maximum, but also the sequence of movements and the course of the forces and torques when executing the lifting movement between the two extreme positions mentioned.
  • the structure of the gears and the arrangement of the moving parts within the lifting mechanism and thus within the work station on the one hand and the torque curve on the other hand can be coordinated with one another in such a way that a relatively small drive motor with comparatively low power is sufficient to carry out the required lifting movement, and the Moving parts of the lifting mechanism require little space.
  • the gear between the lower part and the shaft and the gear between the drive motor and the shaft are designed and coordinated with one another in such a way that when raised to the maximum Lower part and when the lower part is maximally lowered, one of the gears assumes a neutral position.
  • the torque applied to the shaft by the lower part is zero or approximately zero.
  • This can be achieved, for example, by a toggle lever arrangement of the transmission between the shaft and the lower part that is stretched in this position.
  • the torque applied by the lower part to a drive shaft of the drive motor is zero or approximately zero.
  • this can be achieved, for example, by a stretched configuration of a four-bar linkage forming the transmission between the drive motor and the shaft.
  • a shaft crank connected to the shaft in a rotationally fixed manner can be provided as a common element and in particular as the only common element of the two transmissions.
  • a preferred embodiment provides that when the maximum stroke of the lower part is carried out, a motor crank connected to the drive motor rotates through a larger angle than the shaft.
  • the angle of rotation of the motor crank can be larger by approximately 20 to 70%, in particular by approximately 40 to 60%, than the angle of rotation of the shaft.
  • the maximum stroke of the lower part corresponds to a rotation of the shaft by approximately 80° to 120°, in particular by approximately 100°.
  • the maximum stroke path of the lower part corresponds to a rotation of a motor crank connected to the drive motor by approximately 140° to 160°, in particular by approximately 150°.
  • the upper part can be lowered and raised relative to the frame in order to carry out an upper stroke.
  • a particularly advantageous possibility for carrying out an upper stroke results from a structure of the lifting mechanism and a way of supporting the lifting mechanism on the frame, as explained above in connection with one of the other independent aspects of the invention.
  • the possibility of executing an upper stroke is not mandatory with such a concept, but can be implemented in a simple manner in order to integrate an upper stroke function into the lifting 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 lifting mechanism provides that the shaft is mounted eccentrically on the frame with respect to its axis of rotation. A rotation of the shaft about its axis of rotation consequently results in a movement of the axis of rotation relative to the frame with a vertical component. This movement of the shaft can be used to carry out an upper stroke movement of the upper part.
  • a lifting mechanism with a centrally mounted shaft and without an upper stroke function can easily be converted into a lifting mechanism with an upper stroke function by changing the central bearing of the shaft to an eccentric bearing.
  • the eccentricity of the eccentric bearing of the shaft by changing the eccentricity of the eccentric bearing of the shaft, the relationship between the angle of rotation of the shaft and the resulting stroke of the upper stroke movement can be changed.
  • the upper part is supported on a base of the lifting mechanism, preferably comprising a frame, with the shaft being rotatably mounted in the base.
  • the shaft is stored 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 support members spaced apart along the shaft can be provided, on which the shaft is each mounted eccentrically with respect to its longitudinal axis.
  • the shaft rotates, the shaft consequently moves in a vertical direction relative to the support members in order to thereby carry out the upper stroke function.
  • the shaft can be fixed relative to the frame during its rotation in the longitudinal direction
  • the support members are capable of an evasive movement in the longitudinal direction. In this way, the horizontal component resulting from rotation of the eccentrically mounted shaft can be recorded.
  • the support members each comprise a roller or a roller.
  • the lower stroke and the upper stroke run in opposite directions to one another.
  • the two lifting movements can therefore support each other, whereby the maximum power to be applied by the drive motor can be significantly reduced.
  • the effective working stroke of the working unit given by the difference between the lower stroke and upper stroke is approximately 75 to 85mm, preferably approximately 80mm.
  • the maximum amount of the upper stroke is approximately 0.2 times to 0.3 times the maximum amount of the lower stroke.
  • the maximum amount of the upper stroke is preferably around 20 to 30mm, preferably around 25mm.
  • the maximum amount of the understroke is approximately 95 to 115mm, preferably approximately 105mm.
  • the invention also relates to a packaging machine with at least one work station according to the invention.
  • the work station shown is a deep-drawing station of a packaging machine, which comprises a frame 11 standing on the floor with two upper support profiles 51 and two lower support profiles 37, which extend in a conveying direction, also referred to below as the longitudinal direction, in which a film web, not shown in a fundamentally known manner through the packaging machine and thus through the in Fig. 1 shown deep-drawing station is conveyed through.
  • Chain guides (not shown) are attached to the inside of the support profiles 51 for guiding conveyor chains, also not shown, which hold the continuous film web laterally in a generally known manner.
  • Film plane 55 represents the reference plane for the tool of the deep-drawing station shown.
  • this reference plane is usually slightly below the upper edge of the support profiles 51.
  • the tool is a working chamber, also known as a deep-drawing chamber, which includes a lower part 15 and an upper part 13.
  • the height of this reference plane above the floor on which the frame 11 of the deep-drawing station and the packaging machine stand is predetermined by the packaging machine, so that the movements of the lower part 15 and the upper part 13 of the working chamber of the deep-drawing station must be coordinated with the position of the film plane 55 .
  • the lower part 15 and the upper part 13 are supported by a lifting mechanism explained in more detail below, which is inserted as an independent functional unit into the work station between the two lower support profiles 37 and the two upper support profiles 51.
  • the lifting mechanism is carried as a whole by the frame 11 and is supported exclusively on the support profiles 37 by means of support elements in the form of rollers 35.

  • Fig. 1 three shafts 17 are rotatably mounted in the area of their ends in the longitudinal beams 20 of the frame.
  • the already mentioned support rollers 35 are connected to the end faces of the shafts 17, so they are not directly connected to the longitudinal beams 20 of the frame.
  • the support of the lifting mechanism on the frame 11 is therefore characterized by the fact that the shafts 17 are supported on the one hand via the rollers 35 on the support profiles 37 of the frame 11, and on the other hand the shafts 17 support the longitudinal beams 20 and thus the frame and consequently the entire lifting mechanism carry.

  • the motor 19, is only connected to the rear shaft crank 25 in the side view selected here via the motor crank 31 and the drive coupling 33.
  • the design of the lifting mechanism chosen in the two exemplary embodiments described here is advantageous in several respects: With the working chamber closed in accordance with 3a and 3b the toggle lever arrangements formed by a shaft crank 25 and the associated push rods 23 are each in a vertically extended position. The bottom part 15 therefore exerts no torque on the shafts 17 in this neutral position of the transmission. The entire effective weight is diverted directly via the shafts 17 and the support rollers 35 connected to the shafts 17 into the longitudinal beams 37 and thus into the frame of the work station.
  • the four-bar transmission 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 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 joint axis 63 between the motor crank 31 and the drive coupling 33, and the joint axis 67 between the drive coupling 33 and the shaft crank 25.
  • This stretched state results in that the shaft crank 25 can no longer rotate clockwise, and the overall effective weight of the lower part 15 and the gearbox cannot therefore 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 therefore free from external forces. The motor 19 therefore does not need to be subjected to a holding current to generate a torque that counteracts a weight force. In particular, when the working chamber is open, it is possible to easily replace the force-free motor 19 if necessary or to separate it from the motor crank 31 for other reasons.
  • the movable 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, which is explained in more detail below, an optimal force or torque curve is achieved without disadvantageous force or torque peaks over the entire opening or .Closing movement of the working chamber, i.e. over the entire angle of rotation of the motor crank 31 or the shafts 17.
  • the movement sequence of the lower stroke of the lower part 15 described above is independent of the way 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 caused to carry out the lower stroke of the lower part 15 simultaneously results in the shafts 17 lowering.
  • the lowering of the shafts 17 results in a downward movement of the entire lifting mechanism, including the upper part 13, which is supported on the shafts 17 via the columns 27, relative to the frame and thus relative to the film plane 55.
  • the lowering of the shafts 17 is achieved by eccentrically mounting the shafts 17 on the support rollers 35.
  • This concept can be illustrated particularly well using the Fig. 2a and 3a can be understood, in which the support roller 35 is not shown on the left gearbox. 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, 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 angle of rotation of the shaft 17 - the maximum stroke path of the upper stroke.
  • the eccentric axes 36 With the working chamber closed according to Fig. 3a , i.e. in the extended state of the toggle lever arrangement consisting of shaft crank 25 and push rods 23, the eccentric axes 36 also lie in the common vertical plane of the joint axis 71, joint axis 73 and shaft rotation axis 18. The eccentric axes 36 each lie vertically above the rotation axis 18 of the shaft in question 17, ie the shafts 17 and thus the entire lifting mechanism, in particular including the upper part 13, are lowered to the maximum with respect to the frame.
  • a common plane of shaft rotation axis 18 and eccentric axis 36 includes the above-mentioned angle of approximately 100 ° to the vertical. This angle is the maximum angle of rotation of the shafts 17.
  • the entire lifting mechanism is firmly connected in the longitudinal direction to the spindle 39 and thus to the frame via the spindle nut 41 which interacts with the right column 27, the evasive movement in the longitudinal direction required due to the eccentric movements of the shafts 17 around the support rollers 35 is not caused by the lifting mechanism, but rather carried out by the support rollers 35, which roll on the support profiles 37 of the frame.
  • This can be done, for example, in the Fig. 2a and 3a can be particularly well understood based on the positions of the rollers 35 in the longitudinal direction relative to the columns 27 which are fixed in the longitudinal direction.
  • the support rollers 35 enable the lifting mechanism to be positioned in the longitudinal direction by manually rotating the spindle 39, as already described above.
  • the lifting mechanism is a carriage which 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 beams 20 and the cross beams 22.
  • the shafts 17 are rotatably mounted in this base, which 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.
  • a plate-shaped cross strut 45 for the lower part 15 connecting the two supports 16 of the lower part 15 is shown.
  • the supports 16 and the cross strut 45 of the lower part 15 as well as 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.
  • FIG. 6a and Fig. 6b in particular the symmetrical structure of the individual gears, in which the carrier 16 of the lower part 15 and the shaft crank 25 are arranged between the pair of push rods 23.
  • the guide tabs 61 for vertically guiding the lower part 15 on the columns 27 can therefore be made comparatively simple. This also underlines the extremely robust and low-maintenance overall structure of the lifting mechanism.
  • a further advantage of the lifting mechanism according to the invention is that the integration of the upper stroke movement does not involve 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 also possible in principle.
