Abstract
Description
Technical Field
[0001] This invention relates to a moving device for at least one conveying device, particularly a clamping device for a packaging machine with at least one clamping arm, comprising at least one hinge mechanism to which the conveying device is mounted. Thus, the conveying device can move between at least one first position and at least one second position by means of the hinge mechanism. The invention also relates to a method for moving a conveying device using such a moving device. Furthermore, the invention relates to a packaging machine for filling products, particularly bulk materials, into bags, comprising at least one filling module with at least one filling nozzle and at least one such moving device with at least one conveying device. Background Technology
[0002] In many machines, components, and in particular tools or other transfer modules and / or handover modules, move back and forth between different locations to perform transfer operations and / or move objects or products from one location to another.
[0003] For example, in automatic and / or semi-automatic packaging machines, such as filling bulk materials into bags, empty bags from a storage device are clamped by a clamping device and hung onto the filling nozzle, as designed.
[0004] In this situation, the device has an extremely high mass compared to the empty bags being transferred. Consequently, the energy required to transfer the empty bags is disproportionately high.
[0005] According to the design, the filled bags can then be transferred by a clamping device, for example, to a welding station or a similar location.
[0006] Depending on the design of the packaging machine and / or the arrangement of its components, it is often necessary to move the clamping device or clamping arm back and forth.
[0007] Especially when the bags to be transferred are full, considerable forces can sometimes be applied to the moving mechanism. Consequently, the greatest force occurs particularly at the end of the movement, requiring a large initial force to initiate the motion. Therefore, this enormous force leads to increased wear and necessitates a relatively large motor for operation. Summary of the Invention
[0008] The objective of this invention is to overcome the aforementioned disadvantages.
[0009] This task is accomplished by a mobile device intended to be protected by the present invention, by a method for moving a conveying device intended to be protected by the present invention, and by a packaging machine intended to be protected by the present invention. Preferred further improvements of the present invention are the subject of further protection by the present invention. Further advantages and features of the present invention will be apparent from the general description and the description of embodiments.
[0010] The moving device according to the invention is suitable for moving or transporting at least one conveying device, particularly for moving a clamping device with at least one clamping arm of a packaging machine. Specifically, at least one conveying device is disposed to the moving device. In this case, the moving device includes at least one hinge mechanism to which the conveying device is disposed, wherein the conveying device is movable between at least one first position and at least one second position by means of the hinge mechanism. Thus, at least one preloading device is operatively connected to the hinge mechanism and / or the conveying device to absorb the weight of the hinge mechanism and / or the conveying device when the conveying device moves at least partially and at least partially between the first and second positions.
[0011] Preferably, the conveying device, especially the transfer device, is a machine, tool, clamp, transport module and / or other component.
[0012] By using a preloading device, the weight of the hinge mechanism and / or the conveying device is specifically absorbed, placed, or reduced, thereby enabling a particularly simple and smooth reciprocating motion of the conveying device by means of the hinge mechanism.
[0013] Preferably, the preloading device is mounted to or connected to the hinge mechanism to absorb the forces acting on the entire hinge mechanism, i.e., the forces exerted by the weight of the handling device; that is, to absorb its own weight and the weight of the payload, i.e., the weight of the bag. However, in other designs, the preloading device may also be mounted to or fixed to the handling device, in which case the weight of the handling device, the hinge mechanism, and the payload is also absorbed or reduced in this manner.
[0014] Preloading devices are particularly designed as springs or elastic elements, with hydraulic and / or pneumatic preloading devices being particularly advantageous to use.
[0015] The preloading device is hinged in particular. In this case, the preloading device is hinged on both sides, so that it can move itself in a suitable manner when moving the conveying device or the hinge mechanism. As previously explained, the conveying device can be mounted to the hinge mechanism and / or the conveying device, particularly on one side. The other side is preferably fixed to the housing device, rocker arm, cantilever, wall panel and / or top plate or the like.
[0016] The clamping device is preferably mounted to the housing via a hinge mechanism or, in the embodiments described below, to the base, to the column, or to the frame.
[0017] According to the present invention, the clamping device of the conveying device is preferably reciprocating through a hinge mechanism, wherein the weight of the clamping device and the hinge mechanism is reduced by a preloading device.
[0018] The maximum force of the preload device, in a further advantageous improvement, also results in damping of movement at the end position, where the hinge mechanism may fall into the end position without braking. However, depending on the design, a buffer or other stop may also be provided.
[0019] The moving device according to the invention offers numerous advantages. A significant advantage is that, by reducing the load on the hinge mechanism and / or the conveying device through a preloading device, so-called weightless movement of the hinge mechanism and the conveying device can be achieved. Therefore, the conveying device can be conveniently moved from the first position to the second position or moved back by a motor with exceptional smoothness.
[0020] Therefore, on the one hand, this makes it possible to achieve particularly uniform and continuous motion, and since no large force needs to be overcome, the wear and tear on the motion is very small. Furthermore, especially in cases where the movement is set to be automatic or motor-driven, it is possible to use a relatively small motor for the reciprocating conveying device.
[0021] This is particularly advantageous if the moving device is used, for example, in a machine for filling bulk materials, where the conveying device is designed, for example, as a clamping device for suspending empty bags and removing filled bags from the filling nozzle. Then, the preloading device reduces not only the load on the hinge mechanism and the conveying device when removing the filled bags, but also the load on the filled bags hanging on the conveying device, thereby allowing for further load reduction or low-efficiency and particularly smooth and uniform movement.
[0022] Preferably, the preloading device is hinged. In particular, the preloading device is hinged on both sides, thereby providing suitable movement for the hinge mechanism and / or the conveying device.
[0023] Preferably, the preloading device is arranged above and / or below the hinge mechanism and / or the conveying device, so that the force is substantially offset from above and / or offset or supported from below.
[0024] Particularly preferred is that the movement from the first position to the second position is essentially along an arc-shaped path, particularly a circular path. This can be achieved through a corresponding design of the hinge mechanism.
[0025] In a further advantageous improvement, the preloading device has minimal effect at the apex of the curved path. Thus, the preloading device particularly reduces or substantially reduces the load at the apex of the curved path. This can be achieved, in particular, through the appropriate positioning of the preloading device relative to the hinge mechanism and / or the conveying device, depending on the engagement position of the preloading device.
[0026] Specifically, a preloading device is set or configured in such a way that the conveying device is held in the end position by its own weight, without being lifted or moved back in another direction.
[0027] Preferably, the preloading device includes at least one pneumatic device. Specifically, the preloading device is configured to include at least one cylinder for preloading action.
[0028] Preferably, the maximum displacement of the preloading device defines at least one stop for the displacement of the clamping device. Thus, for example, in the case of a spring, spring stroke, or cylinder, the maximum or set maximum deformation can define the end position. In this way, the radius of movement can be effectively and reliably limited.
[0029] Depending on the design, buffers or similar elements may also be used additionally or specifically to define end points, where the hinge mechanism moves to the end position or remains there on its own.
[0030] Particularly preferred is that the hinge mechanism is designed as a linkage drive. This design allows for a particularly advantageous sequence of movements when linked with the preloading device.
[0031] In a further advantageous improvement, the hinge mechanism includes at least one four-bar linkage. Preferably, at least two interconnected and parallel four-bar linkages are provided. This results in a particularly stable hinge mechanism that ensures a particularly advantageous sequence of movements.
[0032] Preferably, the conveying device is designed as a clamping device with at least one clamping arm, wherein the clamping arm is positioned in a height-adjustable manner. In particular, the height adjustment enables the bag to be reliably hooked onto and removed from the filling nozzle. Moreover, depending on the design, if the conveying device is designed as a clamping device for clamping bags, then during the movement of the hinge mechanism, the bag may initially be lowered slightly due to the tilting of the clamps; when rotated back to the end position, if the clamps are horizontal again, the vertical movement is superimposed again, and the bag is then transferred to the fixed filling nozzle by the clamps.
[0033] Furthermore, when the handling equipment is designed as a clamping device with at least one clamping arm, the provision of a preloading device also reduces the load on the goods being transferred by the clamping arm or the clamping device, such as empty bags and / or filled bags.
[0034] Preferably, at least one actuating device is provided for moving the conveying device or the hinge mechanism. Thus, the actuating device is particularly engaged with the hinge mechanism. However, it can also transfer force to the conveying device, depending on which design is reasonable and advantageous according to the installation state. Automatic reciprocating movement of the conveying device from a first position to a second position can be performed by a motor device for moving the conveying device or for moving the hinge mechanism. The actuating device may in particular include at least one motor device or at least one motor, or be provided by such a motor device. However, depending on the design, at least one pneumatic device or at least one cylinder may also be additionally or specifically included or thus provided.
[0035] The method according to the invention is suitable for moving a transport device by means of the moving device described above. Thus, during the movement of the preloading device between the first and second positions, the weight of the transport device and / or hinge mechanism is at least partially reduced, thereby requiring only a generally continuous and reduced force to move the transport device and / or hinge mechanism.
[0036] The method according to the invention provides the advantages described above. In particular, by design, it is possible to move the moving device with little or no force, or even without applying any force, regardless of the weight suspended to the hinge mechanism or the conveying device. Therefore, smaller motors can also be used for the automatic or automated movement of the conveying device or the hinge mechanism because less force is required. Furthermore, these products are also more durable because less force acts on the individual components, thus resulting in less wear on, for example, the motor.
[0037] As described above, the packaging machine according to the invention is suitable for filling products, particularly bulk materials, into bags, and includes at least one filling module with at least one filling nozzle and at least one moving device with at least one conveying device.
[0038] The packaging machine according to the present invention also provides the advantages described above. Attached Figure Description

[0108] Figure 1 The diagram shows a perspective view of a packaging machine 1 according to the present invention. In the embodiment shown here, the packaging machine 1 includes a bag storage device 2, a bag dispensing device 3, and a transfer device 4 arranged between the two. Here, the bag storage device 2, the bag dispensing device 3, and the transfer device 4 are arranged along line 12.
[0109] The filling module 100 is removed from line 12 and, in the embodiment shown here, is positioned adjacent to the transfer device 4. In the embodiment shown here, empty bags from the storage bag device 2 are delivered to the filling module 100 by means of the transfer device 4. The bags delivered to the filling module 100 are then attached to the filling nozzle 101 of the filling module 100 and filled, and then returned to line 12 by the transfer device 4 and delivered to the bag outlet device 3.
[0110] By arranging the filling module 100 adjacent to line 12 or removing it from line 12, almost any filling module 100 can be used with modules or components of the packaging machine 1 arranged in line 12. In particular, standard modules can also be used, thus eliminating the need for specially designed filling modules 100 for the packaging machine according to the invention, preferably modules that use the same filling technology to fill open bags.
[0111] In the embodiment shown here, the packaging machine 1 is configured as a closed system, and therefore, the various components or modules are housed within the housing devices 11 and 102. Thus, in the embodiment shown here, the sub-components arranged within line 12, namely the bag storage device 2, the bag dispensing device 3, and the transfer device 4, are housed within a common housing device 11. In the illustrated embodiment, the filling module 10 is housed within its own housing device 102.
[0112] By arranging the various components or modules within the housing devices 11, 102, the filling process can be made airtight, allowing hazardous or sensitive substances to be filled using the packaging machine 1. In particular, negative pressure measures or suction can be employed within the packaging machine 1 or the housing devices 11, 102 to prevent leaks during the filling process from entering the environment, allowing for safe handling or even recycling.
[0113] In the embodiment shown here, the storage bag device 2 also includes a bag making device 13, wherein the bag is manufactured for this purpose from the film storage device 14 and provided to the transfer device 4 for use.
[0114] In the embodiment shown here, the bag dispensing device 3 includes a sealing device 15 that can close a filled and still open bag and a conveyor belt 16 for removing the filled and closed bag.
[0115] Since the bag storage device 2, the bag dispensing device 3 and the transfer device are arranged within line 12, and the filling module 100 is arranged to move out from this line 112, the packaging machine 1 according to the invention has a T-shaped arrangement.
[0116] As already explained, this offers several advantages. One advantage is that virtually any (standard) filling module can be used by arranging the filling modules 100 adjacent to each other or by moving the filling modules 100 off line 12. Therefore, on the one hand, existing filling modules 100 can be used. On the other hand, the adjacent arrangement also allows for quick replacement or substitution of filling modules with minimal effort. In known in-line equipment, i.e., equipment where everything is arranged in a single line, it can be difficult to arrange filling technology equipment together due to space constraints, especially the gas filling module 105 with pressure chamber 106 shown in the embodiment. Furthermore, operability or maintainability will be more challenging.
[0117] Another advantage is that the T-shaped design or arrangement of the packaging machine makes particularly compact designs possible.
[0118] Figures 2 to 4 Two perspective views and one front view of the packaging machine 1 are shown to better illustrate the situation of the packaging machine 1. In order to ensure an overview view of the interior of the packaging machine 1 or the various modules or components, the housing panels 17 and 103 are not shown at the housing devices 11 and 102.
[0119] exist Figure 5 and Figure 6 The diagram shows an overview view and enlarged view of the transfer device 4 from the side of the self-discharging bag device 3.
[0120] In this view, the filling module 100 is arranged or positioned adjacent to the transfer device 4, and the filling nozzle 101 of the filling module 100 can also be seen in this view. The feed hopper 104 of the filling module 100, which is connected to a silo containing the product to be filled (not shown above), is also visible here. Thus, the product is fed through the feed hopper 104 into the pressure chamber 106 within the filling module 100, or here, the product from the gas filling module 105 is fed to the filling nozzle 101.
[0121] In this view, it can be seen that the transfer device includes a first clamping device 5 and a second clamping device 6, which are respectively placed on different sides 7, 8 or the base 18 of the transfer device 4.
[0122] As shown here, the base 18 of the transfer device 4 is cylindrical in shape and is suspended in the embodiment shown. In the illustrated embodiment, the base 18 is suspended from the guide rail 19, wherein the base 18 with clamping devices 5 and 6 in this view can be moved to the left from the line 12. This mobility of the transfer device 4 will be shown and described in detail below.
[0123] In addition to the mobility of the transfer device 4 or its base 18, in the embodiment shown here, the base 18 can also be rotated 90° reciprocally. By reciprocatingly rotating the base 18 of the transfer device 4, and arranging the first clamping device 5 on the side 7 of the base 18 and the second clamping device 6 on the side 8 of the base 18, the bags from the storage device 2 can be fed from the line 12 to the filling module 100 or the filling nozzle 101 by means of the transfer device 4 through the reciprocating rotation of the base 18 by 90°. When the base 18 or the transfer device 4 rotates in the opposite direction, the second clamping device 6 contacts the already filled bag at the filling nozzle 101, and can pick up the bag and send the bag back to the line 12 and to the bag outlet device when the base 18 rotates forward or rotates again.
[0124] exist Figure 6 In the enlarged view, it can be seen that the first clamping device 5 and the second clamping device 6 are located on different sides 7 and 8 of the base 18 of the transfer device 4. From this, one of the two clamping arms 9 of the first clamping device 5 can also be seen.
[0125] As can be seen in more detail in the figures below, in the embodiment shown here, the clamping device 5 includes two clamping arms 9 that can move relative to each other, thus enabling them to be used as a lifting device. Therefore, the clamping arm 9 of the first clamping device can be a clamping device 5 for retrieving an open bag from the bag storage device 2 or the bag making device and attaching it to the filling nozzle 101. For this purpose, in the embodiment shown here, the first clamping device 5, or the clamping arm 9, can also move forward and then retract again, which... Figure 7 and Figure 8 The image is shown purely schematically.
[0126] exist Figure 9 The diagram shows a purely schematic view of the transfer device 4 and the filling module 100 as viewed from the storage bag device 2. Here, the base 18 of the transfer device 4 is rotated such that the second clamping device 6 is oriented in the direction of the filling nozzle 101 of the filling module 100. In this position, the first clamping device 5 is oriented so that an empty bag can be retrieved from the storage bag device 2.
[0127] exist Figure 10 The image shows a purely schematic view of the transfer device 4 and the filling module 100 from the side of the self-discharging bag device 3.
[0128] As can be seen here, the second clamping device 6 is configured to be movable. Therefore, in the illustrated embodiment, the second clamping device 6 can pivot or move forward in the direction of the filling nozzle 101 via the parallelogram structure 20. Thus, the clamping mechanism 10 of the second clamping device 6 can press the still open bag walls of the filled bag together and then move the bag back in the direction of the base 18.
[0129] Subsequently, the substrate 18 can be rotated 90° clockwise, allowing the filled bag to be moved back to line 12 and then delivered to the bag exit device. Simultaneously, while the filled bag is being removed by the second clamping device 6, a new empty bag can be retrieved by the first clamping device 5. As the filled bag is rotated forward to line 12, a new empty bag also exits line 12 and is delivered to the filling nozzle 101.
[0130] exist Figure 10 As can be further seen, the cleaning device 50 according to the present invention is disposed above the second clamping device 6, which will be described in detail in the following figures.
[0131] exist Figure 11 and Figure 12 The image again schematically shows a side view of the packaging machine 1, the transfer device 4, and the filling module 100 as viewed from the direction of the bag ejection device 3. Comparing this view, it can be seen that the transfer device 4 or the base 18, together with the clamping devices 5, 6 attached to them, are designed to be movable or pull-out.
[0132] Therefore, as already explained, in the embodiment shown here, the base 18 is suspended in the upper region and can be moved by the guide rail 19 or the guide rail system 19. Other technical components or parts for moving the base 18 can also be used similarly.
[0133] Since the transfer device 4 or the base 18 of the transfer device 4 can be moved laterally to line 12 in the embodiment shown here, this fact provides sufficient space for maintenance personnel, for example, to maintain the packaging machine 1.
[0134] Therefore, in the removed state of the substrate 18, particularly in the embodiment shown here, all components of the packaging machine 1 can be easily accessed. In particular, the filling module 100 can also be accessed from the side of the filling nozzle 101. However, other inaccessible sides of the bag storage device 2, the bag dispensing device, and the transfer device can also be maintained and / or serviced.
[0135] exist Figure 13 and 14 The middle section shows an overview view and a partial view of the transfer device 4 and the base 18 of the transfer device 4 of the packaging machine 1.
[0136] In this embodiment, the first clamping device 5 and the second clamping device 6 are arranged at a 90° offset on different sides 7 and 8. This arrangement ensures the stacking and transfer of empty bags and filled bags.
[0137] A cleaning device 50 is provided above the second clamping device 6. This cleaning device includes a housing device 64, wherein in the embodiment shown here, a rotatable housing part 65 or a rotatable baffle 66 is provided. The cleaning device 50 will be explained in more detail in the following figures.
[0138] Furthermore, it can be seen that the first clamping device 5 is arranged on the side 7 of the base 18. In the embodiment shown here, it includes two clamping arms 9, which can move, pivot, or move outward relative to each other. Therefore, the clamping arms act as lifting devices and can retrieve or take over empty bags from the storage bag device 2.
[0139] Furthermore, as can be seen from the above figures, the first clamping device 5 is pivotable, allowing it to move forward in the direction of the filling nozzle 101 and also in the direction of the storage bag device 2. Depending on the design, other components of the first clamping device 5, such as a telescopic clamping arm 9, may also be provided.
[0140] exist Figure 15 and Figure 16 In this configuration, the base of the transfer device 4 rotates such that the first clamping device 5 is oriented in the direction of the filling nozzle 101 of the filling module 100. In this position, a bag (not shown) is clamped to the clamping arms 9 by opening the two clamping arms 9, wherein the clamping device 5 moves forward to hang the freely clamped bag onto the filling nozzle 101. Furthermore, a second clamping device 6 with a clamping mechanism 10 can be seen.
[0141] exist Figure 17 and 18 In the middle, it is again shown in a slightly perspective view from an angled upward. Figure 15 and 16 The side view shows the cleaning device 50 above the second clamping device 6, thus obscuring the view of the clamping mechanism 10 of the second clamping device 6.
[0142] exist Figures 19 to 24 The cleaning device 50, which is disposed above the second clamping device 6 according to the present invention, and its operating mode are described in detail in the embodiment shown herein.
[0143] Thus, in the embodiment shown here, the cleaning device 50 according to the invention, provided by means of blown gas, is used to clean the so-called head seam area of the bag to be sealed.
[0144] In addition to the application described herein of the cleaning device 50 according to the invention, it can also clean any other working parts, particularly those related to the packaging machine 1 described herein.
[0145] Here, in Figure 19The diagram schematically shows a general overview view 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 clamping device 6 in the embodiment shown here.
[0146] In this embodiment, the cleaning device 50 includes Figure 19 The two blower plates 51 are not visible in the diagram. In the embodiment shown here, the cleaning device 50 is configured to be enclosed within the housing device 64. This makes an airtight seal between the blower plates 51 and the workpiece to be cleaned possible. To deliver the workpiece or bag to be cleaned to the cleaning device 50, the housing device 64 includes a movable or pivotable housing member 65 or baffle 66, which is in a closed state in the shown view.
[0147] exist Figure 20 The image shows a perspective view of the cleaning device 50 according to the invention, wherein the movable housing 65 or baffle 66 is designed to be in an open state. This shows a clear view of two blower plates 51 located within the housing assembly 64, as illustrated in an embodiment.
[0148] exist Figure 21 In the middle, the components of the cleaning device 50 are shown separately again in a perspective view. The baffle 66 or pivotable housing 65 is also shown in the open state, thus revealing the two blower plates 51 provided in the embodiment shown here.
[0149] In the embodiment shown here, the blower plate 51 includes a plurality of first nozzles 52, second nozzles 53 and third nozzles 54, which are arranged in rows 60, 61 and 62.
[0150] Therefore, the three rows 60, 61, and 62 set here can be supplied with gas in different ways by the first nozzle 52, the second nozzle 53, and the third nozzle 54, thereby blowing the moving airflow to the work area to be cleaned.
[0151] This is achieved by having a first blowing direction 55, which is different from the blowing directions 56 and 57 of the other nozzles 53 and 54 in rows 61 and 62. In particular, preferably and in this embodiment, the first nozzle 52, the second nozzle 53, and the third nozzle 54 are also provided to have blowing directions 50, 56, and 57 that are different from each other.
[0152] In addition, a control device 58, which is not shown in more detail in the figure, is provided, which is adapted and designed to control the nozzles 52, 53, 54 to be staggered at least in time.
[0153] Therefore, in the illustrated embodiment, for the nozzles 52, 53, and 54 in the three rows 60, 61, and 62, a separate air supply pipe 59 is provided within the blower plate 51. Here, two blower plates 51 are provided, and... Figure 22 The image can be schematically shown by obscuring the left-side blower plate 51. By obscuring the blower plate 51, the independent air supply pipe 59a located outside the blower plate 51 or the connector of the air supply pipe 59 for the blower plate 51 can be seen.
[0154] exist Figure 23 and 24 As schematically shown, a suction device 63 may also be provided to suction out gas ejected by the blower plate 51 or other liquids with rotating particles.
[0155] Therefore, in the embodiment shown here, the suction device 63 is functionally connected to the interior of the housing device 64 through the opening 67 of the housing device 64.
[0156] Therefore, in the illustrated embodiment, a suction tube 68 is provided, which is connected to the opening 67. Depending on the design, another suction tube 68 may also be provided on the left side, wherein the opening 67 on the left side is closed by a cover plate 69.
[0157] In the illustrated embodiment, as described above, a baffle 66 is provided to enclose the movable housing 65 or housing assembly 64, forming a substantially airtight cleaning chamber. Depending on the application, the suction device is configured to extract at least a certain amount of gas, or a moderate amount, which is blown into the housing assembly 64 via the blower 51. In particular, it is preferable to extract at least enough gas to create at least a slight negative pressure within the housing assembly 64. This is particularly important for equipment used in dust removal applications. In non-critical operating environments, or in general, a non-airtight housing assembly 64 or no housing assembly 64 may be provided.
[0158] also, Figure 23 and 24 It is also shown that the first nozzle, second nozzle and third nozzle 52, 53, 54 of different rows 60, 61, 62 are connected by different air supply pipes 59a of each blower plate 51.
[0159] Therefore, the different controls of each nozzle 52, 53, 54, or the different rows 60, 61, 62 of these nozzles 52, 53, 54, can also be different for each blower plate 51. Thus, in the illustrated embodiment, a gas wave or moving gas flow can be formed over the entire length and width of the work section to be cleaned, thereby mimicking a blowing pattern by means of oscillating nozzles, particularly without the use of moving parts. The blowing pattern of the oscillating nozzles thus ensures that the bag walls to be joined subsequently are blown apart when cleaning the bag section for the subsequent head seam, thereby removing the product between the bag walls.
[0160] In particular, the oscillating gas jet ensures that the bag opening edges are cleaned before the filled bag is sealed or closed by the moving gas flow. This allows the stacked bag walls or film layers to be opened by the acting gas jet, impacting the inner surface and removing adhering dust or dirt particles. By altering the gas jet, in the appropriate bag design, the side-folded interlayers also separate, thus cleaning this area as well. Each film layer is essentially opened sequentially by the moving or oscillating airflow and cleaned by the airflow that permeates in this way.
[0161] exist Figures 25 to 28 The diagram illustrates the transfer of filled bags to the bag-discharging device 3 via the transfer device 4.
[0162] Therefore, a parallelogram structure 20 is provided, on which a second clamping device 6 with a clamping mechanism 10 is mounted. This structure 20 is also used to remove the filled bag from the filling nozzle 101, or to bring the second clamping device 6 into contact with the filled bag.
[0163] In its basic state, the second clamping device 6 is positioned relatively close to the base 18 of the transfer device 4. In the following... Figure 26 and Figure 27 As can be seen, the second clamping device 6 moves by moving the four-bar linkage forward in the direction of the bag outlet device.
[0164] Thus, it can also be seen that in the embodiment shown here, the sealing device 15 is designed as a welding station 21.
[0165] exist Figure 28 The parallelogram structure 20 is shown schematically in its various positions side by side, and the specially designed parallelogram structure 20 allows the filled bags to be transferred to the bag outlet device 3 in a generally linear or generally straight manner by means of the clamping device 6 of the transfer device 4.
[0166] exist Figures 29 to 33 The image shows, purely schematically, another embodiment of the packaging machine 1 according to the present invention. Here, the construction of this embodiment basically corresponds to the embodiments already described above.
[0167] In particular, the bag storage device 2, the transfer device 4, and the bag dispensing device 3 are arranged on line 12. Compared with the embodiment shown above, instead of the filling module 100 being moved out of line 12 and arranged adjacent to the transfer device 4, the two filling modules 100 are arranged adjacent to each other outside line 12.
[0168] In order to select one of the two filling modules 100 for use, in the embodiment shown here, the transfer device 4 is configured to be movable so that it can be positioned in front of one or the other filling module 100. In this way, for example, products can be quickly changed, or the filling module 100 can be maintained, for which the transfer device 4 can be slid or moved in front of the filling module 100 that is to be used or does not require maintenance.
[0169] In parallel with the fact that the transfer device 4 can slide in line 12, according to the design, the transfer device 4 may also be additionally provided with mobility or movability transverse to line 12 in the embodiment shown above.
[0170] To ensure that the self-storage bag device 2 can reliably pick up the bags and that the filled bags can be reliably transferred to the bag dispensing device via the transfer device 4, the various components of the transfer device 4 can be configured to be movable accordingly.
[0171] However, by design, the bag storage device 2 and / or the bag dispensing device 3 can also move together so that there is always an optimal distance between the components.
[0172] exist Figure 34 The side view schematically illustrates the moving device 200 according to the invention, which is integrated into the packaging machine 1 according to the invention. A conveying device 250 is thus placed on the moving device 200; in the illustrated embodiment, this conveying device is a first clamping device 5. In the embodiment shown here, the clamping device 5 includes two clamping arms 9 by means of which the bag-making device 13 removes an empty bag and delivers it to the filling nozzle 101 of the filling module 100.
[0173] Thus, in the embodiment shown here, the moving device 200 includes a hinge mechanism 201 and a preloading device 204, wherein the conveying device 250 can be moved from a first position 202 or an initial position 211 to a second position 203 or an extended position 212 by means of the hinge mechanism 201.
[0174] Thus, in the embodiment shown here, the preloading device 204 is arranged above the hinge mechanism 201 or the conveying device 250, and includes a pneumatic device 207 with a cylinder 213.
[0175] According to the design, the moving device 200 can also be connected from below to the hinge mechanism 201 or the conveying device 250.
[0176] Here, the preloading device 204 is hinged to the housing device 11 at its upper free end, and the other end is hinged to the hinge mechanism 201 in the illustrated embodiment.
[0177] exist Figure 35 The image shows a moving device 200 according to the invention on the side. Figure 34 An enlarged view of the first position 202. In the embodiment shown here, the double arrows indicated by dashed lines indicate that the clamping device 5 or clamping arm 9 is designed to be height adjustable, thereby allowing the clamping arm 9 to move up and down, particularly for hanging the bag onto the filling nozzle 101.
[0178] Furthermore, it can be seen that the hinge mechanism 201 is designed as a linkage drive component 208 or a four-bar linkage 209, thereby enabling particularly appropriate movement of the conveying device 250.
[0179] The preloading device 204 is thus configured to absorb the weight of the conveying device 250 and the hinge mechanism 201, thereby enabling the linkage or four-bar linkage 209 to move particularly smoothly and evenly, wherein most of the weight is absorbed by the preloading device 204, or, in the embodiment shown here, by the pneumatic device 207 or the cylinder 213.
[0180] Therefore, it is particularly possible to move the conveying device 250 smoothly and / or pneumatically and / or by means of an electric motor. It is particularly possible to design an actuating device 210, which is not shown in more detail in the figures, to be relatively small, especially smaller than the conventional moving device 200. Thus, for example, the motor device or electric motor and / or pneumatic device or at least one cylinder can be designed and sized accordingly.
[0181] exist Figure 36 and 37 The image shows two different perspective views of one embodiment of a mobile device 200 according to the present invention, in which the preloading device 204 is not shown.
[0182] It can also be seen here that the conveying device 250 or the first clamping device 5 with two clamping arms 9 is arranged to the hinge mechanism 201.
[0183] Therefore, from Figure 37 As can be clearly seen, the hinge mechanism 201 in the embodiment shown here includes two parallelly arranged linkages 208 or four-bar linkages 209, which are connected together or synchronized. Figure 38 The image shows a moving device 200 according to the invention, wherein the hinge mechanism 201 is in the intermediate position 215.
[0184] exist Figure 39 The diagram illustrates the underlying principles. Figure 38 An enlarged view of the moving device 200. Thus in Figure 39 The dashed lines schematically indicate that the hinge mechanism 201, the linkage 208, or the four-bar linkage 209 moves along the arc-shaped path 205, thereby causing the conveying device 250 to also move in an arc-shaped, approximately circular, or approximately semi-circular motion. Thus, in Figure 39 The individual links 216 and connecting members 217 of the linkage 208 or the four-bar linkage 209 can be seen very clearly.
[0185] In the embodiment of the mobile device 200 shown here, the preloading device 204 or pneumatic device 207 or process cylinder 213 is designed such that the action or preloading effect at the vertex 206 of the arc path 205 is minimized.
[0186] Thus, the connecting rod 216 of the linkage 208 is generally vertical in this position, so that the conveying device 250 rests against or is supported by the connecting rod 216 with essentially no load in this position, thereby reducing the load, and the minimal function of the preloading device 214 is safe.
[0187] In the end position or in the first position 202 and / or the second position 203, the preloading device 204 can act as a maximum and / or restrict movement, thereby forming a stop.
[0188] However, in the illustrated embodiment, a buffer 218 is provided, on which the left link 216 and / or hinge mechanism 201 remain at the end position.
[0189] exist Figure 40 and 41 The image shows an embodiment of a moving device 200 according to the invention, in a side view and an enlarged view, the moving device having a conveying device 250 or a clamping device 5 with a clamping arm 9 placed thereon in the other end position (i.e., the second position 203 or the extended position 212).
[0190] In this position, the left link 216 of the linkage 208 rests against the right buffer 218. The conveying device 250 has then moved completely to the right, so in the embodiment shown here, the clamping device 5 or clamping arm 9 can hang the empty bag onto the filling nozzle 101.
[0191] Furthermore, it can be seen here that in the embodiment shown, the preloading device 204 engages at position 214 between the two linkages 208 or the four-bar linkage 209. For this purpose, a pneumatic device is attached here to a support between the two connecting members 217 of the two linkages 208.
[0192] Depending on the design, the weight of the filled bag can be absorbed by the preloading device 204 when the bag is removed from the filling nozzle 101. However, in the embodiment shown here, the filled bag is removed by the second clamping device 6, then sealed and sent to the bag exit device or conveyor belt 16.
[0193] In particular, the movement of the conveying device 250 is achieved by the moving device 200 according to the invention, and in this case, the movement of the first clamping device 5 can be carried out in a basically force-reducing manner because the weight of the conveying device 250 is absorbed or reduced by the special design of the preloading device 204 and the hinge mechanism 201.
