Definitions
- the invention relates to packaging machine construction and there a vertical bagging machine. Such packaging machines are well known.
- DE 195 35 510 A1 discloses a vertical tubular bag machine with a film web drawn off from a supply roll by means of a take-off.
- a forming shoulder is used for forming the film web into a film tube and a format tube for receiving and filling the film tube.
- a longitudinal sealing device is provided for welding the longitudinal edges of the film web and for producing a longitudinal seam of the film tube.
- a transverse sealing device with two sealing jaws movable relative to one another is used to produce transverse seams on the film tube and a separating device for separating the generated tubular bag from the film tube.
- a mechanism is provided for holding the sealing jaws, and a drive for moving the transverse sealing device to move the sealing jaws relative to each other.
- transverse sealing device In order to open and close the transverse sealing device on the one hand very quickly and on the other hand transverse sealing device to move up and down to allow rapid transverse welding of a continuously moving film tube has in this known flow wrapper the drive on two linear motors, of which the first linear motor for a movement of the transverse sealing device in a first direction (the vertical) is provided, and the second linear motor for exerting a movement in a second direction (the horizontal) is used to move a sealing jaw in this direction, or both sealing jaws via a gear to cause an opposite movement.
- the linear motors are connected to each other via a connection, and each linear motor consists of a primary part and a secondary part. Transmissions for producing an opposing sealing jaw movement are known in great variety.
- the known drive has the disadvantage that a part of a linear motor is directly connected to a part of the other linear motor, resulting in a low stability of the entire drive.
- a cross is provided as a connection between the linear motors, the two bars extending transversely to each other.
- a part of the one linear motor and, on the other hand, a part of the other linear motor are fastened to the different beams.
- a guide is also provided parallel to a beam.
- a part of a linear motor is attached to a stationary mount. His other part is attached to one side of the cross.
- Part of the other linear motor is attached to the other side of the cross, and its other part is movable relative to this part and connected to the transverse sealing device.
- the proposed innovation has the advantage that the drive is very stable.
- the two parts of the different linear motors are mounted on opposite sides on the cross and form together with the cross a stable design. While a linear motor is used for moving, preferably for raising and lowering the cross, the transverse sealing device is closed and opened by operating the other linear motor.
- the bars of the cross hold the perpendicular to each other acting parts of the different linear motors.
- the assembled cross is relatively light and therefore movable with relatively little drive energy.
- a stationary primary moves the cross.
- the power supply and the cooling of the primary part can be carried out in an advantageous manner also stationary.
- the second primary part is then movable relative to the cross. This has the advantage that its heat can be better dissipated when it is freely movable.
- its thermal expansion does not disturb the cross.
- the stationary primary part whose heat dissipation hardly heats the cross.
- a relatively heated cross could result in an inaccurate seal jaw orientation due to its thermal expansion, which could result in leaky cross seams.
- the secondary segments are each connected by means of a fastening to the cross (claim 1 1), it is achieved that it is at different expanding components as a result of heating of the magnet equipped secondary part not to warping or deforming the cross is coming. Since the secondary part becomes warmer than the beam bearing it, the secondary part has a greater thermal expansion than the beam if the materials of the secondary part and of the beam are the same or if the secondary part has a greater coefficient of linear expansion than the beam or the cross.
- each secondary segment is connected via its own bottom part or a separate housing with the cross (claim 12). Then the material of the bottom part or of the housing and an intervening gap for the heated length expansions are relevant.
- the bottom parts or the housing at room temperature tight or to form a gap to each other and has the material of the bottom parts or the housing has a smaller, in particular significantly lower coefficient of linear expansion than the material of the cross, the cross is also distorted not with heating of the secondary part and heating by heat conduction to the cross.
- significantly less is meant that the cross expands at a done by operation of the secondary part heating by a greater difference in length than the secondary part.
- Is provided as the material of the bottom parts or the housing steel and as a material of the cross aluminum (claim 14) it is achieved on the one hand that the cross is relatively easy, and therefore is movable without much energy expenditure, and on the other hand that it expands with a larger coefficient of linear expansion than the secondary parts.
- a Curvature of the cross does not occur in such a way. As a rule, no gap must be provided between the secondary parts.
- the length expansion can not be fully considered when heated if according to claim 15, the bottom parts or the housing at room temperature in each case bear against each other to form a gap.
- gaps with a width of about 10 micrometers are generally sufficient.
- As attachment is z. B. a screw or a local bonding.
- FIG. 1 is a side view of a cross, on the vertically aligned beam of which two rails are formed, between which a secondary part of a first linear motor extends, a stationary primary part sitting this linear motor on the rails in order to displace the cross in the vertical direction;
- FIG. 2 is a sectional view of the cross of FIG. 1 cut along A-A of FIG. 1;
- Figure 3 is a side view of the subject of Figure 1, but with something relative to the stationary primary part up set cross;

- Figure 6 is a side view of a vertical bagging machine whose transverse sealing device by means of a drive according to the figures 1 to 5 moves in the vertical direction and also opened and closed;
- Figure 7 is a side view of a cross with two perpendicularly acting linear motors according to Figure 1, but with secondary parts, consisting of a series of separate, each connected to the cross secondary part elements;
- Figure 8 is a sectional view of the cut along B-B of Figure 7 object of Figure 7;
- FIG. 9 shows a side view of the rear side of the object of FIG.
- FIG. 7 with the transverse sealing device of FIG. 4;
- FIG. 10 shows a sectional view of the secondary part for the actuation of the transverse sealing device of FIG. 9 at a low operating temperature of the secondary part
- Figure 1 1 in a sectional view of the secondary part of Figure 10, but at a higher operating temperature
- a forming shoulder 5 for forming the film web 4 to a film tube 6 and a format tube 7 for receiving and filling the film tube 6 (Figure 6).
- a longitudinal sealing device 8 is provided for welding the longitudinal edges of the film web 4 and for producing a longitudinal seam 9 of the film tube 6.
- a transverse sealing device 10 with two mutually movable sealing jaws 1 1, 12 is used to produce transverse seams 13 on the film tube 6 and a separator 14 for separating the generated tubular bag 15 from the film tube 6.
- a mechanism connected to a fastening 39 16 holds the sealing jaws 11, 12 ( FIG. 4, FIG. 6).
- the transverse sealing device 10 is opened and closed and moved up and down to produce two transverse seams 13 simultaneously and along with the continuously moving down film tube 6.

- a drive 17 for moving the transverse sealing device 10 has two linear motors 18, 19 (FIGS. 1 to 5).
- the first linear motor 18 is provided for movement of the transverse sealing device 10 in the vertical 20.
- the second linear motor 19 serves to exert a movement in the horizontal 21 in order to move the sealing jaws 1 1, 12 in this direction in opposite directions.
- the linear motors 18, 19 are connected to each other via a cross 23.
- Each linear motor 18, 19 consists of a primary part 24, 26 and a secondary part 25, 27.
- the two bars 28, 29 of the cross 23 are arranged transversely to each other.
- a guide 30, 31 parallel to a beam 28, 29 is provided on the opposite sides.
- a primary part 24 of the first linear motor 18 is fixed to a stationary holder 32.
- the secondary part 25 of this linear motor 18 is mounted on one side of the cross 23.
- a secondary part 27 of the other linear motor 19 is mounted on the other side of the cross 23.
- the primary part 26 of the second linear motor 19 is movable relative to this secondary part 27 and connected to the transverse sealing device 10 in order to open and close it.
- four carriages 33 for moving the primary parts 24, 26 along the guides 30, 31 are provided in each case.
- the secondary parts 25, 27 are glued to the cross 23 in order to stabilize it.
- the cross 23 and the guides 30, 31 may be made of a single piece of aluminum for thermal expansion reasons, with a separate, hardened guide surface, each guide 30, 31 consisting of two mutually parallel rails 34, 35. Alternatively, rails 34, 35 of hardened steel may be used.
- the cross 23 points to the opposite
- the secondary parts 25, 27 extend over the beams 28, 29 and are in each case glued between two rails in a material recess 36.
- the second linear motor 19 opens and closes the transverse sealing device 10 by a reciprocating movement of its primary part 26 relative to its secondary part 27 and thus to the cross
- the secondary parts 25, 27 are hardly heated in contrast to the primary parts 24, 26, so that the cross 23 does not increase the accuracy of the movement of the sealing jaws 11, 12 undergoes longitudinal expansion as a result of excessive heating.
- the two secondary parts 25, 27 of the cross 23 consist of a series of separate secondary part segments 40 arranged on one another.

- the material of the housing 42 together with respective bottom part is steel. This has a lower coefficient of linear expansion than the material of the cross 23, which is aluminum.
- secondary segment 40 is to be understood as meaning a plurality of magnets 40 in one unit or in each case a single magnet 44.
- a single-screw connection for a group that is bounded laterally, two screws side by side or one single narrow adhesive trace transverse to the longitudinal extent of the secondary part 25, 27 is advantageous. This allows a free expansion of the secondary part segment 40 without the cross 23 being curved thereby.
