In the case of valuable products such as wine, it is desirable and in some cases necessary to remove the bag before filling it evacuated so that the contact of the wine with the oxygen in the air is reduced to a minimum. In some cases it is also desirable, if not necessary, to consider the wine clean before it is filled into the bag and before the bag is closed again with the tap will, the wine with a neutral gas, such as. B. nitrogen to cover.

Various machines have been proposed with which, although great performance is achieved, the but have a large number of disadvantages. The main disadvantage of the known machines is that they have a large number of handicrafts and the responsible ones Operator fatigue prematurely, which affects performance. Another problem is that Difficulty performing all the operations involved in pulling out the tapping, repositioning the filling head and the reinsertion of the dispensing cap.

The invention is based on the object of specifying a filling device that largely automates a

In the graphic representation of FIGS. 1 to 7, a container 20 is a flexible pouch made of polymeric material Material formed, which with a ZapfVerschlag 21 is provided, which can be moved axially into or out of a ribbed pipe socket 22. This is the usual practice a container as it is already in common use and as it is to be used for the invention suitable is.

The first step in filling the container 20 is to place the finned pipe socket 22 in a pipe holder 23 to bring, which, as shown in Fig. 7, consists of two plate-like parts 24 that are spaced apart have from each other and so form a receptacle 25 that the pipe socket 22 between its two ribs 26 and records. The pipe socket holding device 23 is in relation to the frame 30 (Fig. 8) of the machine by a Clamping bracket 31 held, which is clamped around a stand 32 of the frame 30, with its position is adjustable with respect to the stand 32 by rotating about the stand 32 and by raising and lowering it. This is best seen in Figure 8 of the drawings.

After the container is so inserted, a head-like assembly (Fig. 8) is lowered. The head-like The assembly has a closable gripper assembly 35 having four recesses at their lower ends provided fingers 36, which are rotatably mounted at their upper end in the outer wall of a cylinder 37. The cylinder 37 contains a spring-loaded piston 38, whose plunger 39 acts with its rounded end on inwardly directed lugs 40 of the fingers 36, around the To open fingers 36 with respect to the central axis of the cylinder, wherein in the rest position of the piston 38 the

-13-

130013/1285

Finger 36 again assume the closed position shown in Fig. 2 and their recesses 41 the Take up or grip around the flange or the rib 42 of the tap closure 21. The head 35 moves from its Intermediate position in Fig. 1 in an upper position such as shown in Fig. 2 and this enables the fingers 36, the Lift the tap off the ribbed pipe socket 22. The lifting movement is achieved by a lifting cylinder 45 (Fig. 8) attached to the frame 30 and a tubular Support 46 is fixed with liners 47 and 48 at their upper and lower ends on the fixed arranged stand 32 slides and ur.i the tubular support is rotatable. In Fig. 1, the Device 23 an intermediate position which is activated by a locking lever 49 (Fig. 8) is set. If the locking lever 49 is in a lower position, it limits the movement of the the tubular support 46 attached bracket 51 and determines the intermediate position. Is the lock lever like Retracted shown in Fig. 8, it allows the tubular support 46 together with its closed Gripping arrangement 35 a lifting into the position shown in FIG.

In Fig. 9, two arms, which are designated 54 and 55 are shown. The lower arm 54 carries the gripping assembly 35 and the upper arm carries a filling head 56. A swinging cylinder 57 (Fig. 8) moves the arms 54 and 55 back and forth, from the position in FIG. 9 to a position in which the filling head 56 is exactly coaxial with the finned pipe socket 22 is aligned. When this is done, the lifting cylinder 45 will turn again lower, and the position shown graphically in Fig. 3 is achieved. The fill head 56 is on the finned pipe socket 22 lowered. The lower end of the filling head 56,

-14-.

130013/1285

that comes into contact with the upper end face of the pipe socket 22 contains a resistant, made of Soft rubber sealing ring 58 which seals against the pipe socket 22. In this filling section Air is introduced into a small valve cylinder 59, whereupon its piston rod moves downwards and a gas valve 60 opens in the lower end of a multiple valve foot 61, the valve foot the liquid filling valve at its lower end 62 which cooperates with a valve seat 63 in the lower end of the valve head 56. A Gas flow channel 66 leads to an evacuation suction pipe in the frame of the machine (only shown in Fig. 10), so that air is sucked out of the container 20 and the risk of oxygen encountering the in the bag 20 to be filled wine is low.

After a short time, the air introduced into the valve cylinder is discharged again and the valve 60 closes. The section of a filling process shown in FIG. 4 has now been reached when the filling head cylinder 67 (Fig. 4) actuating air is supplied to raise the piston 68. By lifting the piston 68, the Liquid filling valve 62 is raised from its valve seat 63 so that liquid can flow through the liquid channels 70 can flow into the container 20. This section of the filling process is shown in Fig. 4,

Fig. 5 shows the next section of the filling process, in which the piston 68 is driven downward by air introduced into the upper chamber of the cylinder 67, so that the Liquid filling valve 62 closes against valve seat 63 to allow the flow of liquid into container 20 after it has been reached interrupt the intended filling. The achievement of the intended filling can be measured in terms of volume

130013/1285

or a timer can be used, after which the liquid flow is interrupted. Thereafter air is in turn supplied to the valve cylinder 59, whereupon the gas valve opens. If at this point that Gas valve 60 is open, the gas guide channel 66 is not connected to an evacuating suction connection as in the first time in FIG. 3, but to a feed of nitrogen gas so that the oxygen in the room is about the liquid level of the container 20 is displaced, which the possibility of an oxygen induced Damage to the wine or other precious products filled in the container 20 is reduced.

The next section in the filling process is shown in FIG. 6, in which the filling head 56 is lifted away from the pipe socket 22 and reset to the position shown in FIG. 9 by the device of the oscillating cylinder 57 (FIG. 8) is. One more time, the closed gripping assembly 35 aligns with the central axis of the finned pipe socket 22 adjusted, after which the closed gripping arrangement 35 corresponding to the second shown in FIG Portion of a filling operation is lowered, but this time the locking cylinder 50, as shown in Fig. 8, is complete withdrawn and the ZapfVerschluß 21 is complete driven into the ribbed pipe socket 22. As can best be seen in FIG. 2, the Zapf closure ends

21 at its lower end with a conical surface 72, which has an annular, flat shoulder 73, what a Pulling off the tap 21 from the ribbed pipe socket

22 counteracts.

The last step of the filling process is to discard the now filled container 20, which is shown diagrammatically in FIG. 7 is shown. A discharge cylinder 75 is carried on the pipe socket holder 23, with the piston rod 76 of the ejection cylinder 75 on the ribbed pipe socket

The arrangement in front of the table 82 can be adapted to any planning requirements, e.g. B. In many cases, a loading belt is provided immediately adjacent the front edge of the table 82 onto which the filled containers are discarded.

It will be apparent to any knowledgeable user that the main control is electronic or pneumatic or in Combination can be performed. In this embodiment is a combination of electronic and pneumatic control is shown, the main monitoring being a pneumatic circuit, which is shown in detail in Fig. 10 is shown. This works together with a very simple electronic circuit, but it works accordingly known circuits works and is therefore not shown in detail.

10 and 11 are described below, wherein Figure 10 illustrates the pneumatic logic circuit and Fig. 11 shows the various sections and functions of the various working cylinders shows. The following cylinders are shown above the head of Fig. 10: Locking cylinder 50, lifting cylinder 45 (which during some working positions with the working positions of the fingers

The air in line 1 passes through the OR gate and through a flow sensor 101 to a blow-out part 102, the blow-out part 102 being a closable one

opening, as explained below * will.

The air from line 1 also passes through AND gate 103, which also functions as a DND gate Line A receives. The line A continues to convey air through a second sensor 105 to a second blow-out part 104. The delivery line A is also connected to the valve 106 and converts it to its opposite position, whereby the piston of the cylinder 50 is reset, which engages the locking lever from its on the lifting cylinder Position resets. The piston of the lifting cylinder

22 is lifted off, which closes the exhaust opening in the blow-out part 102 and the AND gate function 103 is complete, so that the valve 108 changes into a position in which it enables the actuating cylinder 57, the head-like To put assembly 34 from the position corresponding to FIG. 9 into its other, alternative position, in which the filling head lies at the same level as the pipe socket 22. The blow-out part 104 is adjusted by the filling head closed, while 'valve 95 is now venting the air line A and the air line B supplies air.

The next step, shown in the drawings and in Figure 11 as section 3, is the evacuation phase. Air becomes the AND gate 109, the OR gate 110, the OR gate 111 r to the sensor 112, the blow-out part 113 and promoted to the AND gate function 114. The feeding

-19-

130013/1285

the air line A conveys air to the valve 117 via the OR gate 11O _7, whereby the valve 117 changes its position. As a result, the filling head is lowered onto the upper part of the ribbed pipe socket 22, whereby the scanning blow-out part 118 closes, whereby the end function of the gate 114 is completed. As a result of this, air is conveyed to valve 119, from whose outlet channel the timer 120 is set in motion in order to measure the evacuation time. At the same time the vacuum detector is operated by the vacuum valve 121 via the OR gate 122 and the OR gate 123 from the valve 124, which switches back to the rest position by means of a spring. The valve cylinder 59 is energized, which enables the container to be evacuated via the suction connection (not shown) will.

As a fourth step, the filling phase shown in FIG. 4 and determined by 4 in FIG. 11 is initiated.

After the period of time of the timer 120 has elapsed, the valve 119 changes its position and energizes the fill indicator 126 and completes the and gate function ₅ to switch the valve 127 via the container sensor 112 and the blow-out part 113 through the AND gate 109. As a result, the liquid fill valve 62 is opened by pulling back the cylinder 67, the fill indicator 126 remaining open and an electrical signal energizing an electrical relay (not shown). This relay enables the pulses from two sources to be counted. A first source is formed by a clock generator designed for a test function, which enables the operating functions of the machine to be tested without the product to be filled. A second source is formed by a hygienically clean turbine, which is arranged in the flow of the liquid to be filled into the container and is connected by this.

creib is »whereby the turbine produces zjdhxbai ^ - .s-iapuise. Λχηβ such a turbine is not shown in detail because they are already known and used in common filling devices will.

When the valve 62 is open, the pulses emitted by the turbine, which are proportional to the volume of the bottled liquid are counted. When the adjustable maximum count is reached, a relay function is activated triggered by which a solenoid 129 is excited and at the same time a solenoid valve 130 is actuated to the space above the liquid level with nitrogen gas to cover.

The next step, step 5 in the drawings and the summary table in Fig. 11, is the nitrogen gas purge step and nitrogen blanketing step, respectively. By energizing the solenoid 129, the and gate function is completed _; whereby the valve 94 changes its position, the air line B is vented and the air line C supplies air, the valve 124 returning to its rest position by a spring finally being energized again, ie switched over, via the OR gate 123. This actuates the valve cylinder 59 and enables the cleaning gas to flow onto the surface of the goods in the container. As a result of the switching process described, the valve 95 is also returned to its starting position.

\ in The next step is shown in Fig. 6 and ^ Fig. 11 reproduced by the designation 6 and denotes the reclosing of the container. Since the air line C Air was supplied, the valve of the cylinder 67 (the filling cylinder) could change its position. This was triggered by changing the position of the valve 127, the lifting cylinder 45 by changing the position of the valve 117 via the flow limiter 131 and the Oder gate has been actuated. Air is also applied to a

Half of the AND gate function of 133, the blowout element 134 via its sensor 135 and the outer blowing part 102 via the OR gate 100 and its sensor 101 and the valve 119, which changes position “After a delay of the element 131, the lifting cylinder 45 is excited, whereby the outer blow part 102 is closed, which the AND gate function of valve 133 is completed so that valve 108 changes position. This will make the rocking cylinder 57 or the cylinder 57 performing a reciprocating movement is withdrawn, whereby the blow-out part 134 is closed. This changes the position of valve 93, which changes the position of valve 94 conditional, so that the line C is vented and the line D air is supplied.

The next step is the dropping step. Through the the Line D supplied air is the valve 117 via the OR gate 110 change position. The supplied air becomes one half of the AND gate function of the AND gate

137 close and through the OR gate 111 and the sensor

138 to reach the blow-out part 118. When the lift cylinder 45 is withdrawn to its receiving stop or the tap closure, it closes the exhaust opening 118 and supplements the AND gate function 137, whereupon the valve 139 changes its position and the ejection cylinder 75 is energized. Through the valve 139, the position of the valve 106 is changed and the locking cylinder 50 opens so that the locking lever is set in readiness for a takeover position. This is achieved using a flow adjuster 140 which is like an eject / lift time delay part

acts, the valve 92 has already changed its position or must have changed. By changing the position of the valve 92, the outlet of the valve is the Let air out of line D and feed line E with air.

The last step is not shown in the individual drawings, but is listed as step 8 in FIG. 11. During this step, the entire system is returned to the starting position in which it is in standby position for receiving a next container, this one is achieved by exciting the lifting cylinder 45 and changing the position of the valve 17 as well as by providing the conveying air for a next cycle.

The blow-out parts 102, 113, 118, 104, 134 are essentially provided as sensors that monitor the movements to be carried out by the actuators, whereby they are arranged in a known manner so that the actuators close the blow-out opening, ^so that a change in pressure and thus a change in state at the Entrance of the blow-out part occurs, which is used for further control.
