Description

Technical Field

[0001] The present invention relates to a moving device for at least one handling device, in particular a moving device for a gripping device of a packaging machine, comprising at least one hinge mechanism to which the handling device is attached. The hinge mechanism allows the handling device to be moved between at least one first position and at least one second position. The present invention also relates to a method for moving a handling device using such a moving device, and a packaging machine having such a moving device. Background Art

[0002] In many machines, components and in particular tools or other processing and / or transfer modules are moved back and forth between different locations in order to perform processing operations and / or transfer objects or products from one location to another.

[0003] For example, in automatic and / or semi-automatic packaging machines, for example, when filling bulk materials into bags, the empty bags are taken from a bag storage device by a gripping device and hung at a filling spout. The filled bags can then be transported by the gripping device, for example, to a sealing station or the like.

[0004] Depending on the design of the packaging machine and / or the arrangement of the individual components relative to one another, it is often necessary to shift the gripping device or the gripping arm forwards or backwards.

[0005] In packaging machines, displacement systems are known, for example for conveying filled bags from a filling spout to a sealing station, which have a parallelogram linkage for displacing the bags.

[0006] However, a disadvantage of this system is that, due to the polygon effect, the lifting and lowering movement of the linkage also affects the bag, which at least temporarily changes its shape or volume. The rising and falling of the head area generates air turbulence, which can lead to undesirable product leakage.

[0007] In particular, if the bags are transferred to a closing station and the subsequent bag seams have already been cleaned, leakage of the product and thus contamination of the subsequent seam area must be avoided. Summary of the Invention

[0008] The object of the present invention is to improve the above-mentioned disadvantages.

[0009] This object is achieved by the mobile device provided by the present invention, by the method for moving a handling device provided by the present invention, and by the packaging machine provided by the present invention. The present invention also provides preferred further embodiments. Further advantages and features of the present invention are apparent from the general description and the description of the exemplary embodiments.

[0010] According to the present invention, a moving device for at least one handling device, in particular a moving device for a clamping device of a packaging machine, includes at least one hinge mechanism on which the handling device is mounted. The hinge mechanism enables the handling device to be moved between at least one first position and at least one second position. According to the present invention, the hinge mechanism comprises at least one four-bar linkage with at least one first link and at least one second link, wherein the first link is connected to the second link via at least one coupling element. The coupling element includes at least one receiving portion for receiving the handling device, wherein the first link, the second link, and the coupling element are geometrically coordinated to enable a substantially straight movement or displacement of the handling device from the first position to the second position.

[0011] The handling device is in particular a processing device, a transfer device, such as a machine, a tool, a processing assembly, a gripping device and / or the like, which can be moved back and forth by means of a hinge mechanism.

[0012] Particularly, this carrying device comprises to mobile device or is a part thereof.However, according to design, also can provide independent carrying device, and it is accommodated in or is fixed to mobile device or hinge mechanism.

[0013] The arrangement of the connecting rod and the coupling relative to each other is at least temporarily substantially parallelogram or trapezoidal, wherein parallelogram or trapezoidal should not be understood as meaning that it is actually a parallelogram or trapezoid. In at least one position, the two connecting rods may be parallel to each other.

[0014] The hinge mechanism or the four-bar linkage is designed in particular in a coupling-driven manner, so that a particularly reliable, stable and defined displacement from the first position to the second position and back can be achieved.

[0015] The moving device according to the invention offers numerous advantages. A considerable advantage is that, due to the special design of the hinge mechanism or the specific design of the connecting rods and coupling elements relative to one another, a substantially straight displacement of the handling device is possible, and thus, in the case of a gripping device, a substantially straight displacement of the filled bags hung thereon.

[0016] In conventional displacement systems with a parallelogram-shaped or similar hinge mechanism, the polygonal effect causes the handling device to rise and fall during movement, and these forces also act on the bags hung on the handling device. In this case, the end point is usually lower than the lifting and lowering motion. Alternatively, a lifting and lowering motion may also occur when the end point is higher than the intermediate pivot position. In both cases, the volume inside the bag may change within a short period of time, which can lead to product leakage or pumping out, and thus new contamination of previously cleaned bag seam areas.

[0017] In this case, the transfer path is essentially straight due to the specific design of the hinge mechanism. However, depending on the design, the handling device can preferably tilt slightly during the displacement process without causing a change in the lift or vertical orientation, and thus without triggering a lifting movement. In this case, it is particularly preferred that at least one coupling point is displaced in a straight or linear manner. Around this point (which is usually the central axis of the handling device or gripping device), the remaining part can be slightly tilted depending on the design, depending on the tilt position.

[0018] Preferably, the first connecting rod and the second connecting rod have different lengths. Thus, in particular, the first connecting rod is shorter than the second connecting rod. Preferably, the shorter connecting rod is further away from the second position than the second connecting rod, in particular in the first position or the origin position.

[0019] Particularly preferably, the lower hinge point of the first connecting rod and the lower hinge point of the second connecting rod are arranged at different heights. Thus in particular, the first connecting rod or the shorter connecting rod is arranged higher, or the lower hinge point of this connecting rod is arranged higher.

[0020] Furthermore, it is preferred that the free end or the lower hinge point of the connecting rod is hingedly mounted to the housing device or the frame.

[0021] In an advantageous further embodiment, the coupling element comprises at least one first section and at least one second section, wherein the first section and the second section can be arranged at an angle to one another, and in particular at an angle to one another. In particular, such a design allows for a straight movement of the handling device.

[0022] Preferably, the first link is hingedly received at the first section of the coupling with the second hinge point, and the second link is hingedly received at its second hinge point between the first and second sections of the coupling and / or at the second section of the coupling.

[0023] Preferably, the placement portion for placing the handling device is arranged on the second section of the coupling. The arrangement of the handling device at this part ensures that the handling device can move exclusively straight.

[0024] In an advantageous further embodiment, the arrangement of the second hinge point of the first link of the first section of the coupling and the second hinge point of the second link of the second section are coordinated with each other, wherein the design of the coupling, the dimensions of the links and the mutual attachment of the links are particularly coordinated with each other.

[0025] Preferably, at least one actuating device is set. By means of this actuating device, the hinge mechanism and the carrying device can be transferred to the second position from the first position and then returned.

[0026] Particularly preferably, the actuating device comprises at least one pneumatic device. Thus, such a pneumatic device can in particular comprise at least one cylinder or be provided with at least one pressure cylinder by such a cylinder.

[0027] The method according to the present invention is suitable for displacing the carrying device by means of a movement device as described above. In this case, the carrying device is displaced substantially straightly between the first position and the second position by means of a hinge mechanism.

[0028] In this case, straight means in particular no or substantially no height change or no lifting movement between the first position and the second position. However, depending on the design, the handling device can at least be tilted slightly around the point of straight movement, but this results in no or no relevant lifting movement.

[0029] The method according to the invention offers the advantages already described above.

[0030] The packaging machine according to the present invention is suitable for filling products, in particular for filling bulk materials into bags, and comprises at least one filling module with at least one filling spout, at least one movement device as described above, and at least one handling device. The packaging machine according to the present invention also offers the advantages already described. BRIEF DESCRIPTION OF THE DRAWINGS

[0094] Figure 1 1 shows a perspective view of a packaging machine 1 according to the present invention. In the embodiment shown here, the packaging machine 1 comprises a bag storage device 2, a bag discharge device 3 and a transfer device 4 arranged therebetween. Here, the bag storage device 2, the bag discharge device 3 and the transfer device 4 are arranged along a line 12.

[0095] The filling module 100 is removed from the line 12 and, in the embodiment shown here, is arranged adjacent to the transfer device 4. In the embodiment shown here, empty bags are conveyed from the bag storage device 2 to the filling module 100 by means of the transfer device 4. The bags conveyed to the filling module 100 are thus hooked to the filling spout 101 of the filling module 100 and filled, and then conveyed back to the line 12 by the transfer device 4 and to the bag discharge device 3.

[0096] By arranging the filling module 100 adjacent to the line 12 or moving it out of the line 12, almost any filling module 100 can be used together with a module or component of the packaging machine 1 arranged in the line 12. In particular, it is also possible to use standard modules, so that it is not necessary to equip the packaging machine according to the invention with a specially designed filling module 100, which is preferably a module for filling open-mouth bags using the same filling technology.

[0097] In the embodiment shown here, the packaging machine 1 is designed as a closed device, for which the individual components or modules are arranged in housing devices 11, 102. Thus, in the embodiment shown here, the subassemblies arranged in the line 12, namely the bag storage device 2, the bag discharge device 3 and the transfer device 4, are arranged in a common housing device 11. In the embodiment shown, the filling module 100 is arranged in its own housing device 102.

[0098] By arranging the individual components or modules within the housing devices 11, 102, the filling process can also be hermetically sealed, depending on the design, so that hazardous or sensitive substances can also be filled using the packaging machine 1. In particular, negative pressure measures or suction can be used within the packaging machine 1 or the housing devices 11, 102, so that product leaking during the filling process does not escape into the environment, but can be safely disposed of or even recycled.

[0099] In the exemplary embodiment shown here, the bag storage device 2 also comprises a bag-making device 13 , wherein bags are produced for this purpose starting from a film supply device 14 and are made available to the transfer device 4 .

[0100] In the exemplary embodiment shown here, the bag discharging device 3 comprises a closing device 15 which can close the filled and still open bags, and a conveyor belt 16 for removing the filled and closed bags.

[0101] Since the bag storage device 2 , the bag discharge device 3 and the transfer device are arranged in the line 12 , and the filling module 100 is arranged to be moved out of this line 112 , the packaging machine 1 according to the present invention has a T-shaped arrangement.

[0102] As already explained, this offers numerous advantages. One advantage is that by arranging the filling module 100 to the adjacent side or moving the filling module 100 out of the line 12, virtually any (standard) filling module can be used. Thus, on the one hand, existing filling modules 100 can be used. On the other hand, the adjacent arrangement also allows the filling modules to be quickly exchanged or replaced without much effort. In known in-line systems, i.e. systems in which everything is arranged in one line, it can be difficult to arrange the filling technology equipment together for space reasons, in particular the air filling module 105 with the pressure chamber 106 shown in the embodiment. Furthermore, this would be more cumbersome in terms of operability or maintainability.

[0103] A further advantage is that the T-shaped design or arrangement of the packaging machine enables a particularly compact design.

[0104] Figures 2 to 4 Two perspective views and a front view of the packaging machine 1 are shown in order to better illustrate the situation of the packaging machine 1, wherein, in order to ensure an overview of the interior of the packaging machine 1 or the various modules or components, the housing panels 17, 103 are not shown at the housing devices 11, 102.

[0105] Figure 5 and Figure 6 An overview and an enlarged view of the transfer device 4 as viewed from the side of the bag discharge device 3 are shown.

[0106] In this view, the filling module 100 is arranged or positioned adjacent to the transfer device 4 , with the filling spout 101 of the filling module 100 also visible. Also visible here is the feed hopper 104 of the filling module 100, which is connected to a silo (not shown above) for the product to be filled. Thus, the product is fed through the feed hopper 104 into a pressure chamber 106 within the filling module 100 , or in this case, the product from the air filling module 105 is fed to the filling spout 101.

[0107] In this view, it can be seen that the transfer device comprises a first holding device 5 and a second holding device 6 , which are each arranged on different side faces 7 , 8 of the transfer device 4 or on the base body 18 of the transfer device 4 .

[0108] Here, the base body 18 of the transfer device 4 is shown as a columnar structure and, in the embodiment shown here, is suspended. In the embodiment shown, the base body 18 is suspended from a guide rail 19, whereby the base body 18 with the holding devices 5, 6 can be moved to the left from the line 12 in this view. This movability of the transfer device 4 will be shown and described in detail below.

[0109] In addition to the movability of the transfer device 4 or its base 18, in the embodiment shown here, the base 18 can also be pivoted 90° back and forth. By pivoting the base 18 of the transfer device 4 back and forth and arranging the first gripping device 5 on the side 7 of the base 18 and the second gripping device 6 on the side 8 of the base 18, the base 18 can be pivoted 90° back and forth to allow bags from the bag storage device 2 to be transported from the line 12 to the filling module 100 or the filling spout 101 via the transfer device 4. When the base 18 or transfer device 4 is pivoted in the opposite direction, the second gripping device 6 contacts the now filled bag at the filling spout 101 and can pick up the bag. When the base 18 is pivoted forward or again, the bag is returned to the line 12 and transported to the bag discharge device.

[0110] exist Figure 6 In the enlarged view of FIG, it can be seen that the first holding device 5 and the second holding device 6 are located on different sides 7, 8 of the base body 18 of the transfer device 4. Here, one of the two holding arms 9 of the first holding device 5 can also be seen.

[0111] As can be seen in more detail in the following figures, in the embodiment shown here, the gripping device 5 comprises two gripping arms 9 which can be moved relative to each other so that they can act as a sling. Thus, the gripping arm 9 of the first gripping device can be the gripping device 5 which takes the opened bag from the bag storage device 2 or the bag making device and hangs it on the filling spout 101. For this purpose, in the embodiment shown here, the first gripping device 5 or the gripping arm 9 can also be displaced forward and retracted again, which is Figure 7 and Figure 8 are shown purely schematically.

[0112] exist Figure 9shows a purely schematic view of the transfer device 4 and the filling module 100 as viewed from the bag storage device 2. The base body 18 of the transfer device 4 is pivoted in such a way that the second gripping device 6 is oriented in the direction of the filling spout 101 of the filling module 100. In this position, the first gripping device 5 is oriented so that empty bags can be removed from the bag storage device 2.

[0113] Figure 10 A purely schematic view of the transfer device 4 and the filling module 100 is shown from the side of the bag discharge device 3 .

[0114] It can be seen here that the second holding device 6 is arranged to be displaceable, so that in the embodiment shown, the second holding device 6 can be pivoted or displaced forwards in the direction of the filling spout 101 via the parallelogram 20. Thus, the clamping device 10 of the second holding device 6 can press together the still open bag walls of the filled bag and then move the bag back in the direction of the base body 18.

[0115] The base 18 can then be rotated 90° clockwise, allowing the filled bags to be moved back to the line 12 and subsequently sent to the bag discharge device. Simultaneously, while the filled bags are being removed by the second gripping device 6, new empty bags can be taken by the first gripping device 5. When the filled bags are rotated forward to the line 12, new empty bags are also removed from the line 12 and sent to the filling spout 101.

[0116] exist Figure 10 It can be further seen in the drawing that the cleaning device 50 according to the present invention is arranged above the second clamping device 6, which will be described in detail in the following figures.

[0117] exist Figure 11 and Figure 12 , again purely schematically, shows a side view of the packaging machine 1 and the transfer device 4 and the filling module 100, viewed from the direction of the bag discharge device 3. Comparing this view, it can be seen that the transfer device 4 or the base body 18 together with the gripping devices 5, 6 attached thereto are designed to be movable or extendable.

[0118] For this purpose, as already explained, in the embodiment shown here the base body 18 is suspended in the upper region and can be displaced via guide rails 19 or a guide rail system 19. Other technical components or parts for displacing the base body 18 can also be used similarly.

[0119] Due to the fact that in the embodiment shown here the transfer device 4 or the base body 18 of the transfer device 4 can be moved out transversely to the line 12 , sufficient space is available for maintenance personnel, for example, in order to maintain the packaging machine 1 .

[0120] Thus, in the extended state of the base body 18, particularly in the embodiment shown here, all components of the packaging machine 1 are easily accessible. In particular, the filling module 100 is also accessible from the side of the filling spout 101. However, other inaccessible sides of the bag storage device 2, the bag discharge device, and the transfer device can also be maintained and / or serviced.

[0121] exist Figure 13 and 14 1 and 2 show an overview and a detail of the transfer device 4 of the packaging machine 1 and of the base body 18 of the transfer device 4 .

[0122] In this embodiment, the first clamping device 5 and the second clamping device 6 are arranged 90 degrees apart on different sides 7, 8. This arrangement ensures a superimposed working mode for conveying or transporting empty bags and filled bags.

[0123] Above the second holding device 6, a cleaning device 50 is set, which comprises a housing assembly 64, wherein in the embodiment shown here, a rotatable housing member 65 or a rotatable baffle 66 are set. In the figure below, the cleaning device 50 is explained in more detail.

[0124] Furthermore, it can be seen that the first gripping device 5 is arranged on the side surface 7 of the base body 18 and, in the embodiment shown here, comprises two gripping arms 9, which can be displaced or pivoted relative to each other or moved outwards. The gripping arms thus act as a sling and can take or receive empty bags from the bag storage device 2.

[0125] In addition, it can be seen from the above figure that the first clamping device 5 is arranged to be pivotable, so that it can be displaced forward in the direction of the filling spout 101 and in the direction of the bag storage device 2. Depending on the design, for example, a telescopic clamping arm 9 or other components of the first clamping device 5 can also be provided.

[0126] exist Figure 15 and Figure 16 In the embodiment shown here, the base body of the transfer device 4 is pivoted in such a way that the first gripping device 5 is oriented in the direction of the filling spout 101 of the filling module 100. In this position, a bag (not shown) is gripped to the gripping arms 9 by opening the two gripping arms 9, whereby the gripping device 5 is shifted forward in order to hook the gripped bag to the filling spout 101. The second gripping device 6 with the clamping device 10 can also be seen.

[0127] exist Figure 17 and 18 , again shown in a slightly perspective view from above Figure 15 and 16, whereby the cleaning device 50 above the second clamping device 6 is hidden so that the clamping device 10 of the second clamping device 6 can be better observed.

[0128] exist Figures 19 to 24 The cleaning device 50 arranged above the second holding device 6 according to the invention and its mode of operation are described in detail in the embodiment shown here.

[0129] Thus, in the exemplary embodiment shown here, the cleaning device 50 according to the invention is provided for cleaning the so-called head seam region of the bag to be closed by means of blown air.

[0130] In addition to the use described here of the cleaning device 50 according to the invention, it can also clean any other working parts, in particular working parts in connection with the packaging machine 1 described here.

[0131] Here, in Figure 19 1 shows a schematic overview of the transfer device 4 of the packaging machine 1 according to the invention, wherein the cleaning device 50 according to the invention is arranged above the second holding device 6 in the embodiment shown here.

[0132] In this embodiment, the cleaning device 50 includes Figure 19 The two blower plates 51 are not visible in the drawing. In the embodiment shown here, the cleaning device 50 is enclosed in a housing device 64. This allows for an airtight seal between the blower plates 51 and the workpiece to be cleaned. To allow the workpiece or bags to be cleaned to be introduced into the cleaning device 50, the housing device 64 includes a movable, or here pivotable, housing element 65 or a baffle 66, which is in a closed position in the illustrated view.

[0133] exist Figure 20 1 and 2. A perspective view of a cleaning device 50 according to the present invention can be seen in which movable housing member 65 or baffle 66 are designed to an open state. This shows a clear view of two blast plates 51 shown as an embodiment in the housing device 64.

[0134] exist Figure 21 , the components of the cleaning device 50 are shown separately in a perspective view again. Also shown here is a baffle 66 or a pivotable housing member 65 in an open state, thereby allowing the two blast plates 51 provided in the embodiment shown here to be seen.

[0135] In the embodiment shown here, the blower plate 51 comprises a plurality of first nozzles 52 , second nozzles 53 and third nozzles 54 , which are arranged here in rows 60 , 61 , 62 .

[0136] Thus, the three rows 60, 61, 62 provided here can apply air in different ways by the first nozzle 52, the second nozzle 53 and the third nozzle 54, thereby blowing the moving air flow to the working part to be cleaned.

[0137] This is achieved in that the first nozzle 52 or the first nozzle 52 of the first row 60 has a first blowing direction 55 that is different from the blowing directions 56, 57 of the other nozzles 53, 54 or nozzles 53, 54 of the rows 61, 62, respectively. In particular, it is preferred and also provided in the present embodiment that the first nozzle 52, the second nozzle 53 and the third nozzle 54, respectively, have blowing directions 50, 56, 57 that are different from one another.

[0138] Furthermore, a control device 58 is provided, which is not shown in greater detail in the drawing and is suitable and designed for controlling the nozzles 52 , 53 , 54 at least in a temporally offset manner.

[0139] To this end, in the embodiment shown, separate air supply pipes 59 are provided in the blast plate 51 for the three rows 60, 61, 62 of nozzles 52, 53, 54. Two blast plates 51 are provided here, and Figure 22 In the figure, the blast plate 51 on the left is shown schematically. By hiding the blast plate 51, the independent air supply pipe 59a outside the blast plate 51 or the joint of the air supply pipe 59 for the blast plate 51 can be seen.

[0140] exist Figure 23 and 24 As shown schematically in FIG. 5 , a suction device 63 may be further provided to suck out the air ejected by the blast plate 51 or other liquids with rotating particles.

[0141] For this purpose, in the exemplary embodiment shown here, the suction device 63 is functionally connected to the interior of the housing device 64 via an opening 67 of the housing device 64 .

[0142] Thus, in the embodiment shown, a suction pipe 68 is provided, which is connected to the opening 67. Depending on the design, another suction pipe 68 can also be provided on the left, wherein the opening 67 on the left is closed by a cover 69 on the left.

[0143] In the illustrated embodiment, as mentioned above, a baffle 66 by a closed movable housing member 65 or housing unit 64 is provided to form a basically airtight cleaning chamber. Depending on application, the suction device is adjusted to at least suck out the amount of air or generally suck out the amount of air, which is blown into the housing unit 64 by the blast plate 51. Particularly, it is preferred to at least extract enough things so that at least a slight negative pressure is formed in the housing unit 64. This is particularly important for the equipment used in the dust removal field. In non-critical working environments, or generally, a non-airtightly sealed housing unit 64 or no housing unit 64 can be provided.

[0144] also, Figure 23 and 24 It is also shown that the first nozzles, the second nozzles and the third nozzles 52 , 53 , 54 of different rows 60 , 61 , 62 are connected by different air supply pipes 59 a of each blast plate 51 .

[0145] Thus, the different control of the individual nozzles 52, 53, 54 or the individual rows 60, 61, 62 of these nozzles 52, 53, 54 can also be different for each blower plate 51. Thus, in the illustrated embodiment, it is possible to generate an air wave or a moving air stream over the entire length and width of the working portion to be cleaned, thereby simulating a blowing pattern by the oscillating nozzles, in particular without the use of moving parts. Thus, the blowing pattern of the oscillating nozzles ensures that, when cleaning the bag portions for the subsequent head seam, the bag walls to be subsequently joined are blown apart, thus clearing the product from between the bag walls.

[0146] In particular, the oscillating air jets ensure that when cleaning the bag opening edges before the filled bag is closed or sealed by the moving air flow, the overlapping bag walls or film layers are opened by the air jets, allowing the air jets to strike the inner surface and thereby remove adhering dust or dirt particles. By varying the air jets, in corresponding bag designs, the side folds can also separate from each other, thus cleaning this area as well. The individual film layers are actually opened one after another by the moving or oscillating air flow and cleaned by the penetrating air flow.

[0147] exist Figures 25 to 29 The figure schematically shows that the filled bags are transferred to the bag discharge device 3 by the transfer device 4 or the moving device 200 according to the present invention.

[0148] Thus, a substantially parallelogram-shaped structure 20 is provided, on which, in the embodiment of the displacement device 200 according to the invention shown here, a second gripping device 6 with a clamping device 10 serving as a handling device 250 is arranged. This structure 20 is also used to remove filled bags from the filling spout 101 or to bring the second gripping device 6 into contact with filled bags.

[0149] From this Figure 25 In order to describe the construction of the parallelogram structure 20 in more detail, a purely schematic perspective view of a mobile device 200 according to the present invention is shown. Here, the mobile device 200 has a second gripping device 6 serving as a handling device 250, which in the packaging machine 1 described above removes the filled bags from the filling spout and transfers them to the closing device 15.

[0150] Thereby, the moving device comprises a hinge mechanism, to which the transport device or handling device is attached or the second holding device 6 is attached in the embodiment shown here.

[0151] In the design shown here, the hinge mechanism 201 is designed as a four-bar linkage 219 , which comprises a first link 204 and a second link 205 , which are connected in the upper region via a coupling element 206 .

[0152] The first link 204 and the second link 205 are hingedly mounted to the housing device at their lower hinge points 207 and 208, respectively. The upper second hinge points 215 and 216 are hingedly connected to the connecting member 206.

[0153] In order to achieve the desired straight or substantially linear movement of the handling device 250 , the lengths and arrangements of the first link 204 and the second link 205 of the coupling 206 are geometrically coordinated.

[0154] For this purpose, the coupling element 206 in this embodiment has a first section 211 and a second section 212 , which are arranged at an angle 213 to each other. Here, the first connecting rod 204 is placed on the first section 211 and the second connecting rod 205 is placed on the second section 212 .

[0155] The second section 212 is designed or arranged substantially horizontally here and provides a mount 214 for the handling device 250 or, in the embodiment shown here, for the second holding device 6 .

[0156] In the embodiment shown here, the first link 204 is shorter than the second link 205 , wherein the lower or first hinge point 207 of the first link 204 is arranged higher than the lower or first hinge point 208 of the second link 205 .

[0157] Furthermore, in the embodiment shown here, the upper hinge point or the second hinge point 216 of the first link 204 is arranged at a lower height or lower than the second hinge point 215 of the second link 205 .

[0158] The dimensions and arrangement of the connecting rods 204, 205 and the coupling 206, as well as the special connection of the connecting rods 204, 205 and the special connection of the transport device 250 at the coupling 206, make it possible to achieve a substantially linear movement of the transport device 250 according to the invention and preferred embodiment by means of the hinge mechanism from the first position 202 to the second position 203.

[0159] Furthermore, it can be seen that in the illustrated embodiment, an actuating device 217 is provided in order to move the hinge mechanism and thus the transport device 250 from the first position 202 back into the second position 203 .

[0160] In the embodiment shown here, the actuating device 217 comprises a pneumatic device 218 , which here comprises a cylinder 220 .

[0161] In the basic state, Figure 25 and 26 As shown, in the embodiment shown here, the handling device 250 or the second holding device 6 is relatively close to the base body 18 of the transfer device 4 in the first position 202. Figure 27 and 28 In the figure, it can be seen how the second clamping device 6 is displaced in the direction of the bag discharge device 3 by the parallelogram structure 20 and passes through the middle position ( Figure 27 ) moves to the second position 203 ( Figure 28 )of.

[0162] Also visible here is the closing device 15 , which in the example shown here is designed as a welding station 21 .

[0163] exist Figure 29 In the figure, the various positions of the parallelogram structure 20 shown side by side show that, due to the special design of the parallelogram structure 20, the filled bags are transferred to the bag discharge device 3 approximately in a line or approximately straightly with the help of the clamping device 6 of the transfer device 4, without any lifting movement at the bag discharge device 3.

[0164] Thus, in the embodiment of the displacement device 200 according to the invention shown here, in the packaging machine according to the invention, it is possible to achieve that the filled bags are not subjected to lifting movements during their transfer to the closing device 15 and / or to the bag discharge device, unlike in conventional systems and conventional systems with a hinge mechanism in the form of a four-bar linkage due to the polygon effect. Thus, in known systems, the transport device rises and falls during its movement, and these forces also act on the bags suspended from the transport device 250 or the second gripping device 6. Consequently, in known displacement systems, the volume inside the bags can change within a short period of time, which can lead to product leakage or the release of dust, which can soil previously cleaned bag seams.

[0165] Due to the special design of the hinge mechanism, the transport path is essentially straight, in this case horizontal. Although the handling device 250 at the mobile device 200 can be tilted slightly, this does not result in a change in the travel or vertical orientation. In this regard, the hinge mechanism 201 is coordinated or designed so that one point of the coupling or the second section 212 of the coupling 206 is linear. The remaining sections may tilt slightly around this point depending on their position.

[0166] exist Figures 30 to 34 , a further embodiment of a packaging machine 1 according to the invention is shown purely schematically. The construction of this embodiment corresponds essentially to the embodiments already described above.

[0167] In particular, the bag storage device 2, the transfer device 4 and the bag discharge device 3 are arranged to the line 12. Compared to the embodiment shown previously, not only is the filling module 100 moved out of the line 12 and arranged adjacent to the transfer device 4, but two filling modules 100 are arranged adjacent to each other outside the line 12.

[0168] In order to selectively use one of the two filling modules 100, the transfer device 4 is arranged in a movable manner in the embodiment shown here so that it can be arranged in front of one or the other filling module 100. In this way, for example, a quick change of products is possible, and maintenance of the filling modules 100 is also possible, for which purpose the transfer device 4 can be slid or moved in front of the filling module 100 to be used or which does not require maintenance.

[0169] In parallel with the fact that the transfer device 4 can slide in the line 12 , depending on the design, the transfer device 4 can also be additionally provided to be movable or displaceable transversely to the line 12 , as in the previously shown embodiment.

[0170] In order to ensure that bags can be taken out from the bag storage device 2 reliably and that the filled bags can be transported to the bag discharging device reliably via the transfer device 4 , the various components of the transfer device 4 can be configured to be displaceable accordingly.

[0171] However, depending on the design, the bag storage device 2 and / or the bag discharge device 3 can also be displaced so that there is always an optimal distance between the individual components.
