In Fig. 1a a device 39 or a complete system for filling and/or decanting bulk material is shown, with the aid of which a container bag 55 can be filled via a tubular container bag 4 without contamination.

For this purpose, the container bag 4 is clamped on a housing 8 or a wall 9 of the housing 8 between seals 2 , 3 . For this purpose, a groove 28 is provided between the two seals 2, 3 acted upon by compressed air, into which the end of the container bag 4 is pushed. Seals 10 and 12 in the outlet nozzle 6 are activated, as will be explained below, in order to seal a film tube 7 in such a way that no dust can get into the film tube.

The ridge is in the form of an annular ridge 19 which is connected to the adjustable lid 5 or annular body which is a flat or thin annular structure and upwards with respect to the base of the container 8 or towards an inlet opening or an upper inlet opening of the container 8 is aligned and runs approximately parallel to a longitudinal central axis 85 of the container 8 .

Furthermore, the web 19 or the flat or thin ring-shaped structure is aligned coaxially with the longitudinal central axis 85 of the container (8).

The web 19 or the flat or thin ring-shaped structure can be adjusted with the cover 5 up and down in the direction of the longitudinal central axis 85 and the seals 2, 3 can be inserted or led out from below into a gap 86 between two. It is also possible that the gap 86 serves to accommodate part of the film tube 4 and that one or the upper end of the gap 86 can be closed on its upper side with the aid of a seal or a component connected to a housing part 14 or a sealing element 87.

In connection with the two seals 2, 3 and a part of the film tube, the web 19 forms a sealing device with the aid of which and with the aid of the seals and an adjusting device or a pneumatic system the container bag 4 can be secured and/or sealed.

After the bulk material has been transferred from the housing 8 into the container bag 4, which is tied off with a closure 23, it can be disposed of via the outlet nozzle 6, as described below.

The tubular container bag 4 is created by tying off its lower end with the aid of a closure element 23 .

The second or upper end of the container bag 4 is sealed with the aid of at least three sealing rings 1, 2, 3 ( Fig.1a ) is sealed in the work steps described below in such a way that, particularly when filling and decanting the bulk material, no or very small particles are released into the ambient air.

The individual pressure-loadable sealing rings 1, 2, 3 are each offset with respect to the longitudinal center axis 85 of the device 39 for filling bulk material with one another and arranged at a distance from one another.

The first seal 1 is fixedly arranged on the movable cover 5 and can be moved up and down together with the movable cover 5 .

The movable cover 5 has the upright web 19 which can be pushed into one groove 28 so that one end of the hose of the container bag 4 is guided around the web 19 and between the two activated seals ( 1 ) can be sealed.

The three seals consist of a hollow profile body whose cross section can be either round, polygonal or rectangular. The first and outer seal 1 has approximately the same outside diameter as the seal 2 which is arranged above the two seals 1 and 3 .

The tubular container bag 4 is guided with its upper end between the opposing profiles of the seals 2 and 3 and is sealed by the seal 3 as described below. The activated compressed air applied seal 3 will, as shown later, press the film tube against the web 19 of the cover 5.

The overall system 53 has according to Fig.1b among other things, at least one support frame 54, in which the container bag 55 filled with bulk material is accommodated, so that the bulk material can be transferred into the collecting bag provided underneath or into the tubular container bag 4. The fourth seal 10 and the fifth seal 12 ( 2 ) are activated in order to seal the film tube 7 in such a way that as little or no dust as possible can get into the film tube 7.

The outer or first seal 1, the middle or second seal 2 and the inner or third seal 3 can be activated by means of compressed air via a compressed air system, not shown in the drawing, depending on the process status. All seals 1-3 are each arranged at a different height.

The second seal 2 is connected to the stationary housing 8 or to an outer housing part 14 arranged on the housing 8 of the device 39 .

The third seal 3 is arranged between the first and second seals 1, 2 on the fixed housing 8 of the device 39 or an inner housing part 66 of the device 39 with respect to the longitudinal direction of the housing.

According to Fig. 1a the container bag 4 is tied off with a closure 23 and can be severed below the tying point, as described below.

Depending on the status of the process, the seals can be supplied with compressed air or activated individually or together. For this purpose, a compressed air channel 44 is provided, which supplies the seals 1 to 3 with compressed air, depending on the process status of the device 39 .

The entire system is in accordance with Fig.1a consists of the cylindrical or polygonal housing 8 with the cylindrical outer wall 9 on which an outlet nozzle 6 for disposing of the container bag 4 or film tube 7 is provided on the side. The outlet port 6 is laterally connected at an angle to the housing 8, in which a film tube 7 according to 2 included and can be extracted as described below.

The outer or first seal 1 and the inner or third seal 3 are relieved ( 3 ) and the lid 5 is lowered to the lowest position P3, the ends of the tubular sack 4 being fixed to the sack by means of adhesive strips 26 and the central seal 2 remaining activated and holding the sack.

According to 4 the tubular container sack or filler neck 4 is still held and sealed by means of the central seal 2, with a new tubular container sack 4' being pulled onto the lowered lid 5 which is sealed at the lower end by means of a closure 23 to which a still to be filled container bag 55 connects.

The lid 5 ( figure 5 ) is now raised to the middle position P2 and the outer seal 1 is activated, whereby the middle seal 2 remains activated and holds the first tubular container sack 4, for this purpose the web 19 can be inserted into the Groove 28 are inserted and is then sealed by the seals 1-3, which are supplied with compressed air by means of a pneumatic system, not shown in the drawing.

In 6 When the lid is raised to the middle position P2 and the outer or first seal 1 is activated, the middle or second seal remains activated thereby holding the first tubular container sack 4.

Figure 6b shows a section Figure 6a with seals 1 to 3 below on an enlarged scale. The advantageous arrangement of the three seals 1 to 3 facilitate the disposal process of the emptied container bag 4 with the help of the film tube 7 ( 7 ) via the outlet nozzle 6, as explained below. For this purpose, the container bag 4 is pulled up into the area of the inlet opening of the outlet connection. The new container bag 4' is connected to the cover 5 and sealed with the aid of the closure 23'
In the Figures 7a to 23 the disposal process of the emptied container bag 4 via the outlet nozzle 6 is illustrated.

The outlet nozzle 6 consists ( Figure 7a ) from a tubular housing which is provided laterally at a connection opening in the housing 8 and is firmly connected to this connection opening. As explained below, the film tube ( 23 ) meandering drawn up and laid down in an intertwined manner on the outer circumference of the outlet nozzle 6 and sealed at its both ends by means of seals 29-31.

In Figure 7a a representation of a nozzle closure 22 with a compressed air connection 43 is also shown, which is used to monitor the sealing condition of the seals with the emptied container bag 4 and to dispose of this contamination-free via the outlet nozzle 6.

The nozzle closure 22 with the compressed air connection 43 is connected to the compressed air channel 44 (7b), which can be activated by a compressed air system, not shown in the drawing, and which initiates the sealing process of the film tube 7 .

The nozzle closure 22 also includes a lid 25' having a handle 24, by means of which the nozzle closure 22 can be moved or held and inserted into or removed from the tubular outlet nozzle, as described below.

The cover 25' is placed on a tubular housing 32 of the nozzle closure 22 with the aid of the seal 30 and sealed.

The housing 32 of the nozzle closure 22 is closed at the other end with the aid of the cover 25' ( Figure 7c ) and the annular plate-shaped seal 29 which abuts against the front edge of a housing part 32' of the nozzle closure 22. The housing part 32 of the nozzle closure 22 is according to Figure 7a inserted into the outlet socket 6 and sealed with the help of the seal 12 ( Figure 7c , 7d , 8th ).

The seal 12 is wrapped around at both ends on the wall of the housing part 32 of the housing part 32 ( Figure 7C ) and is thus located with its two ends on the inside of the wall of the housing part 32 and on the Outside over the entire length of the wall of the housing part 32 and thus seals the housing part 32 against the inside of the outlet connector 6.

In this way, the two ends of the seal 12 are clamped between the wall of the housing part 32 of the nozzle closure 22 and the inside of the outlet nozzle 6 . As a result, the socket closure 22 in the outlet socket 6 is sealed.

The wall of the body part 32 of the nozzle closure 22 is provided with numerous holes 63 through which compressed air can pass, so that the seal 12 can expand and bear against an inner wall 41 of the outlet nozzle 6, thus increasing the sealing effect. With the help of the seal 12, the film tube 7 is sealed in the outlet nozzle 6.

The outer end of the housing 32 is held together by means of a threaded rod 60, the inner end of the threaded rod 60 being welded to a cover 25 of the housing 32 of the nozzle closure 22. The other end of the threaded rod 60 (7c A) extends through an opening 65 in the lid 25' of the nozzle closure 22 and is provided with the cap nut 31, with the help of which the two outer ends of the nozzle closure 22 are held together and thus the lid 25 and 25′ in each case abut and seal against the two ends of the housing part 32 of the nozzle closure 22 .

According to Figure 7b the fourth seal 10 and the fifth seal 12 are relieved, with the connection piece closure 22 being removed from the outlet connection piece 6 .

According to 8 the operator reaches into the outlet socket 6 with his hand and is protected from contamination by the film tube 7 . In doing so, he grasps the previous tubular, emptied container bag 4 in order to pull it into the film tube 7 .

9 shows that the emptied tubular filler neck 4 can be pulled outwards through the film tube 7 and the outlet neck 6 and is thus free of contamination ( figure 10 ) can be disposed of in the film tube 7 that is still to be separated. The separated film tube 7 remaining in the outlet connection 6 is sealed by a first closure 11 and the film tube 7 led out of the outlet connection 6 with the enclosed container bag 4 is completely sealed to the outside with the aid of a second 11' and third closure 11" and can now be connected to the enclosed Foil tube 4 are disposed of without contamination

According to 10 the film tube 7 with the emptied tubular container sack 4 contained therein is tied with the two closures 11' and 11", the end of the film tube 7 with the tubular container sack 4 enclosed therein then being severed between these two closures 11' and 11".

According to Figure 11a When the nozzle closure 22 is reinserted into the outlet nozzle 6, the fifth seal 12 and the fourth seal 10 are pressurized and the nozzle closure remains sealed. The lid 5 is raised to the highest position P1. The outer seal 1 is subjected to the required pressure so that the tubular filler neck is tightly sealed with the container bag 4' and at the same time allows the lid 5 to be lifted into the highest position P1.

Figure 11b shows the cover 5 with the three seals 1 to 3 on an enlarged scale. The web 19 of the cover 5 presses the tubular filler neck 4' into the groove 28. The groove 28 is formed by an outer wall 68 of the housing part 66 and the second, with respect to the base of the device 39, offset upwards and external seal 2, in which the web 19 is inserted with the aid of an actuating cylinder, not shown in the drawing. The third seal 3 has an outside diameter that is slightly smaller than the inside diameter of the second seal 2. The film tube of the container bag 4' is in this position ( 11 ) around jetty 19 around and then passed through the space between the opposing seals 1 and 2. The two seals 10 and 12 are still not pressurized, but the seal 1 is, so that the end of the container bag 4' received in the gap 86 remains clamped and is sealed. The second seal 2 and the third seal 3 are not yet activated.

The housing part 66 provided on the housing 8 is connected to a flange 67 . The downwardly extending cylindrical socket 14 is also connected to the flange 67 and encloses the two seals 1 and 2.

According to Figure 12a and 12b When the lid 5 is lowered to the middle position P2, the outer seal 1 continues to be pressurized with the required pressure via the compressed air line, not shown in the drawing, so that the tubular filler neck 4' is sealed and thereby the lift of the lid 5 to the middle Position P2 allows. The seal 2 is now also subjected to pressure, so that the film tube 4' remains clamped in the groove 28 and is sealed. As a result, the seal 2 is also pressed against the outer wall 68 of the housing part 66 and the film tube 4' is clamped in the process. As a result, the tubular connecting element 4' is sealed off from the outside.

The jetty 19 ( Figure 12b ) of the cover 5 can now be pulled out of the groove 28 and the seal can be activated with a defined pressure. After the cover 5 has reached the middle position P2, the middle seal 2 and the seals 1 and 3 can be subjected to full pressure, so that the hose-shaped connecting piece 4' is sealed.

According to Fig.13 the tubular connection element 4' is tied on and the container bag 55 connected to it can be filled, with all seals 1, 2 and 3 remaining activated with the full pressure.

Out of 14a It can be seen that after the container bag 55 has been filled, the tubular connecting element 4' and the container bag 55 are tied off with two fasteners 23' and 23'' and the container bag 55 can now be removed without contamination. For this purpose, the tubular filler neck 4' and container bag 55 ( Figure 14b ) between these closures 23' and 23". In this process step, all seals 1, 2 and 3 are activated with full pressure. This position corresponds to the initial situation already described and the next emptying process can take place in the same order as previously described.

In the figures from 15a to figure 23 the contamination-free disposal of the tubular connection element or container bag 4 is described.

How out Figure 15a and figure 16 shows that a piece of the film tube 7 is consumed with each filling process, which is folded and applied axially and meanderingly to the outlet connection 6, so that a length of several meters can be achieved. The amount consumed in one filling process is, for example, 0.4 m, so that with a total length of the film tube of 7.2 m, approx. 18 fillings are possible.

According to FIG. 15b, the connection piece closure 22 is again accommodated in the outlet connection piece 6 and the tubular film 7 pulled onto the outlet connection piece 6 is clamped and sealed in a circumferential groove 36 formed between a movable ring 33 and a counter-holder 34. The clamping effect is achieved in that the movable ring 33 is pressed against a seal 13 which is provided between the movable ring 33 and the counter-holder 34 in the groove 36 of the counter-holder 34 . The counter-holder 34 is fastened to a socket shoulder 37 by means of screws 69 and is welded to the outlet socket 6a. The clamping effect of the film tube 7 is made possible with the aid of the seal 13 which is accommodated in a groove 36 provided in the counter-holder 34 . The clamping effect and thus the attachment and sealing of the film tube 7 is achieved with the aid of the seal 13, the contact pressure of the movable ring 33 on different ways, as described in various embodiments below, can be done.

A corresponding clamping device can be produced with or without auxiliary power, e.g. B. the clamping device can be operated mechanically, magnetically, pneumatically, as in the Figures 22c to 22i is explained.

In order to slip a new film tube 7 over the stationary outlet connection 6 attached to the housing 8, the seals 10 and 12 must be relieved and the connection closure 22 and a housing 35 removed ( figure 16 ).

To 17 one end 40 of the film tube 7 is folded forward on the outer circumference of the outlet nozzle 6, and the film tube 7 is clamped in the groove 36 between the movable ring 33 and the counter-holder 34 with the aid of the counter-holder 34 and the seal 13. The film tube 7 is thereby sealed and secured.

According to 18 a new film tube 7' is slipped over the rest of the film tube 7 and pulled onto the socket shoulder 37, the end of the new film tube 7 being closed with the closure 11'.

As Figure 19a shows, the new tubular film 7' is fixed and sealed on the socket shoulder 37 with the aid of a clamping element 20. For this purpose, the end of the film tube 7 ′ is clamped in the clamping element 20 .

How out Figure 19b As can be seen, the tensioning element 20 consists of a metal band 70 with a hook 71 in which a toggle lever lock 72 engages and is tensioned, so that the film tube 7 ′ is clamped and sealed with the aid of the tensioning element 20 . A C-shaped profile seal 61 with the embedded metal band 70 is used to reinforce a groove 38 Has adjusting screw, change the diameter of the clamping ring and increase or decrease the contact pressure on the outlet nozzle 6 when the adjusting screw is actuated for this purpose.

According to 20 an operator reaches into the outlet socket 6 with his hand and, with the aid of the film tube 7', pulls the previous or old film tube 7 out of the outlet socket 6 without contamination.

In 21 the film tube 7 is completely received in the film tube 7' and tied off with two closures 11' and 11". Now the end of the film tube 7' lying outside of the outlet nozzle 6 can be removed from the in the outlet 6 remaining part of the film tube 7 'separated and disposed of.

According to 22a If necessary, the new film tube 7' can be pressed inwards into the circumferential groove 36 in the direction of the outer circumference of the outlet socket 6 using a tool such as a rope or a template, with the film tube 7' then being connected to the movable ring 33 ( Figure 22b ) is pressed against the seal 13 provided in the groove or the gap 90 and fixed and sealed with the aid of a clamping element 20 . Now the other end of the film tube 7' can then be reinserted into the outlet socket 6 and sealed by means of the closure 11'.

In a first embodiment of the clamping and sealing device Figure 22b the clamping and sealing device with the clamping element 20 is shown on a larger scale. According to the arrow above, the movable ring 33 clamps the front or second end of the film tube 7 ′ against the seal 13 in the groove or gap 36 which is accommodated in the counter-holder 34 . The counter-holder 34 is secured in the socket shoulder 37 with the aid of one or more screw bolts 62 . According to FIGS. 1a and 22b, the socket shoulder 37 is firmly connected or welded to the outlet socket 6.

According to one embodiment Figure 22c , which is an enlarged view of the Figure 22a 12, another clamping and sealing device 75 is shown. The movable ring 33 is pulled against the counter-holder 34 with the aid of a plurality of magnets 56a. A plurality of threaded spindles 51 are firmly connected to the movable ring 33 in order to release the clamping and sealing device. The threaded spindles 51 extend through bores 82 in the socket shoulder 37 and protrude from a rear surface 83 of the socket shoulder 37 so that a threaded nut 50 can be screwed onto the free end of the threaded spindle 51 . By tightening the threaded nut 50, the movable ring 33 is removed from the magnets 56a, so that the film tube 7' can be inserted into the groove 36 or guided out of the groove 36.

With the help of a pneumatic or electric cylinder 56b ( Figure 22d ) the lifting movement of the mobile ring 33 is generated by a piston rod 57 connected at one end to the mobile ring 33 and at the other end to the pneumatic or electric cylinder. With the help of the lifting movement of the piston rod 57, the movable ring 33 can be adjusted and thus the groove 36 can be opened or closed.

In the following examples 22e to 22i, the opening or closing of the groove 36 is represented by differently designed adjusting devices.

Figure 22e has a clamping and sealing device 77 for adjusting a rack 58, which opens or closes the groove 36 with the aid of a rack and pinion gear 56c.

Fig. 22f has a toggle lever clamp 56d as an adjusting device, which is connected to the movable ring 33 via an extension linkage 59 and in this way enables the movable ring 33 to be adjusted.

22g shows the toggle clamp 56d, with the help of which the movable ring 33 can be adjusted.

Fig. 22h Figure 12 shows a clamping and sealing device 80 having a lead screw 56f rotatably connected at one end by means of a rotatable bearing such as a ball bearing. The threaded spindle 56f can be adjusted with the aid of a thread provided in the socket shoulder 37 so that the groove 36 can be opened or closed.

In 22i a clamping and sealing device 81 is designed as a pneumatic device, to which a pneumatic sealing ring 56g belongs, which can close or open the groove 36 with the aid of compressed air. The compressed air is supplied via a pneumatic system, not shown in the drawing.

According to Fig.16 and 23 the new film tube 7 'is applied to the outlet nozzle 6 and the nozzle paragraph 37. The housing 35 can now first be mounted on the socket shoulder 37 and then the socket closure 22 can be reinserted into the outlet socket 6 . The seal 10 and the seal 12 are then activated in order to seal the film tube 7' in such a way that as little dust as possible can get into the film tube.
