Definitions

  • the invention relates to a device for filling a meterable amount of flow agent into packaging with an annular pump piston that can be moved in a cylinder, the inlet end and the outlet end of the pump chamber each being closed by a valve and the outlet end being immersed in the open packaging to avoid foam formation. and with a drive device with a cam disk, the pump piston and the piston rod being hollow and the drive device having at least two rotatably mounted levers which are in drive engagement with one another.
  • Such a filling device is known for example from DE-B-1 144 144. With this device the filling is to be improved insofar as the free fall of the jet of the liquid to be filled there is to be switched off in order to avoid the foaming which is particularly evident when filling milk. Such foam formation not only affects the quality of the milk, but also has an adverse influence on the filling accuracy.
  • the known device is now operated in such a way that the distance between the rising filling level in the packaging and the outlet opening emitting the amount of liquid is kept substantially constant during the filling process. This results in more constant pressure and flow conditions and also a higher filling capacity.
  • the object of the invention is therefore to improve the filling device of the type mentioned in such a way that the filling volume can also be readjusted or converted without major conversion work, the overall machine preferably being of simple design, in particular with regard to pump pistons, metering pistons and outlet valves.
  • the outlet end has an outlet nozzle attached to the end of the piston rod opposite the piston and the emptying valve
  • the inlet valve is arranged on the cylinder
  • the levers of the drive device are in adjustable drive engagement with one another
  • the drive device engages around the piston rod
  • the piston rod can practically be designed as an immersion tube, which is why the outlet nozzle with the drain valve is arranged at its outlet end.
  • the inlet valve is therefore conveniently arranged on the cylinder. Due to the adjustable drive engagement between two levers in operative engagement with each other, the desired dosing volume can be changed over without special assembly work being required.
  • the seals required in the device according to the invention are located in conventional and therefore easily controllable places, so that not only milk, fruit juices but also fats and oils can be filled.
  • the filling accuracy of the new device easily meets the requirements of the calibration law, and the filling volumes can even be changed with the desired accuracy. This changeover or readjustment of the filling volume is flexible and is carried out steplessly by the mentioned threaded spindle with the nut.
  • the lever which can be brought into engagement with the cam disk is connected to at least one air cylinder.
  • One air cylinder engages at the point on the drive-side lever at which a roller follows a cam disk in order to withdraw the roller from the cam disk and in this way generally prevent pumping operation when required, for example if there is no packing to be filled under the outlet nozzle is detected.
  • a second air cylinder can be provided to retract the described engagement end of the lever from the cam disk by an even greater distance into a cleaning position in which the second lever, which is in drive engagement with the first lever the piston rod and thus the entire device in a cleaning position.
  • the device can be cleaned without disassembly and can also be sterilized in such a position at the same time or afterwards (cleaning in place).
  • the emptying valve and the outlet nozzle designed as a nozzle can be removed and replaced by a cleaning pot having an outlet flange and a further outlet flange can be attached to the outlet-side end of the cylinder.
  • a cleaning pot having an outlet flange and a further outlet flange can be attached to the outlet-side end of the cylinder.
  • a first preferred embodiment is characterized in that the inlet and the drain valve are resiliently biased into the closed position and that the outlet end of the outlet nozzle has a sieve. While the arrangement of a sieve on the outlet nozzle is known per se, in connection with the above features and due to the spring-loaded valves, a particularly simple device results which can be used in particular for milk and juices without pulp and, with a few simple drives, shows hardly any susceptibility to faults and little maintenance required.
  • valves can be moved by separate control devices.
  • venting of the device can take place at the beginning of operation in that an air cylinder ensures the opening of the inlet valve in order to be able to vent the lines when the product or product flows in for the first time.
  • the controllability of at least one of the valves is expedient in order to cut pulp located between the seat and the valve disk.
  • an air cylinder provides sufficient force to apply the shear function, as will be explained in more detail below in connection with the description of the figures.
  • a cross bar is fastened to the outlet end of the outlet nozzle and if both valves have cutting edges and can be controlled by an air cylinder.
  • neither the viscosity of the product to be filled, nor its pulp or the like can be an obstacle to the function of the device provided according to the invention, because the valves have cutting edges and are both controlled in such a way that each valve is properly closed.
  • the cross bar at the outlet-side end of the outlet nozzle also serves as a stop for the possible movement stroke of a valve rod in order to simplify the drive of the valve which is furthest away from a controlling air cylinder.
  • the object of the invention is further advantageously developed in that the feed valve can be controlled via an upper inlet valve body and the drain valve via a valve rod that can be coupled to the valve body.
  • the device described above allows liquids to be filled into finished packaging while avoiding foaming by the piston rod not moving to the bottom with its outlet-side outlet nozzle during the suction stroke and the product to be filled discharging during the subsequent pumping stroke, whereby at the same time the outlet end of the outlet nozzle is always kept above the liquid level, in other words when filling the outlet nozzle slowly moves away from the packaging base. It is particularly expedient here if the movement is controlled in such a way that the distance between the lower edge of the outlet nozzle and the liquid level gradually increases in the course of filling.
  • this increase in distance in the course of filling can be controlled perfectly and has the advantage that, in the case of packaging, the open end of which is to be closed, for example by a folding base after complete filling, the liquid level below the area of the folding base, ie the area with the fold - and embossing lines remain.
  • the liquid level can also be very close to the outlet end of the spout in this embodiment at the beginning of the filling, only has to increase in the course of the filling so that at the end of the filling of the spout has moved out of the overall package during the Liquid level is more or less just below the area in which the embossing and folding lines run in order to ensure that the then filled packaging is sealed properly.
  • FIG. 1 The overall structure of the double filling device is shown in FIG. 1.
  • a supply vessel a with the liquid or the product b indicated schematically therein, which can have a first level c and a second liquid level c 'located above it.
  • a probe d senses that the first level c of the liquid has been exceeded, and a second safety probe d 'emits a special closing signal to the product inlet when the maximum upper liquid volume c' has been reached.
  • the flow vessel a is connected via a valve 2 to an inlet pipe e for cleaning liquid on the one hand and to a valve 3 which, during normal operation, allows air to enter through line f through air filter g.
  • valve 2 is opened and valve 3 closed, so that the sterilizing liquid can flow through the entire supply vessel with the product valve 1 and all the units located below, to be described.
  • valve 2 is closed and remains closed in normal operation.
  • the valve 3 is opened in order to allow the inflow of air through the air filter g during the product inflow into the supply vessel a. It is assumed that this regulation of the liquid level c or c 'in the flow vessel a is possible in a conventional manner.
  • the inflow of the product comes from the schematically indicated line h and via the valve 1 controlled by the probe d. This ensures that there is sufficient liquid in the flow vessel a and allows a smooth flow into the actual filling device. This is shown generally as double line i and j, the divider connection k being connected to the inlet line 12, which can also be seen in FIGS. 4 and 8 above.
  • the inlet valve 4 is located at the upper end of the pump cylinder 50, while the drain valve 5 is provided at the outlet end of the piston rod 8 with the pump piston 54.
  • FIG. 1 shows the cleaning position in which the air cylinder 7 with the membrane 8 (see also FIG. 4) ensures opening of the inlet valve 4.
  • the pump piston 54 is located in an extension 50 ′ of the cylinder 50, so that cleaning liquid flowing from top to bottom can flow around the ring-shaped pump piston 54.
  • a cleaning pot 1 is arranged in the form of a hollow cylinder closed on one side, which is screwed on in a sealing manner via a seal m and an internal thread n (dashed line 4 below) after the outlet connection 54 'with valve 5 and pretensioning spring 53 (FIG 4) are removed.
  • the cleaning pot 1 has an outlet flange o for connection to a double drain line for cleaning liquids p, the upper branch of which is connected via a second outlet flange g.
  • the cleaning is carried out in such a way that from above the membrane 8, cleaning fluid flowing down through the valve 4 flows both into the hollow piston 6 down into the cleaning pot 1, exits there, the space between the outlet-side end of the piston 6 and Fills the inner wall of the cleaning pot 1 in order to flow out via the drain flange o and the drain line p.
  • this cleaning liquid also rinses the pump piston 54 on the outside in order to pass the piston rod 6 on the outside as far as the discharge flange g and is also discharged there via the drain line p.
  • the cleaning pot 1 In product operation, the cleaning pot 1 is to be thought of as being removed, so that the state shown in solid lines in FIG. 4 is reached, and then the packaging designated by 10 according to FIG. 1 is at the bottom, as will be explained more clearly with reference to FIG.
  • the stroke H of the pump piston 54 is finally indicated in FIG. 1, for example, the pump piston 54 being located in the production mode at the upper end of the double arrow H and with the same edge at the lower height of the double arrow H.
  • the space 9 fills with liquid, the product, which is supplied from the supply vessel a from above.
  • the air cylinder 7 opens the inlet valve 4 so that air can escape against the inflow direction of the liquid.
  • the right unit j is constructed symmetrically to the left unit i and therefore need not be described again.
  • FIGS. 4 and 5 relate to the drive and the movement of the device, so that first of all the more precise structure, here for example the unit j, is described with reference to Figures 4 to 6.
  • a stationary main carrier 26 shown in FIGS. 4 and 5 holds a guide rod 25, which is also stationary, via a bridge 27, 27 '.
  • the master or pump cylinder 50 of the unit j is carried over the holder 51 (FIGS. 4 and 6).
  • the unit generally referred to as clutch r, is used to transmit the drive movement from the drive device shown mainly in FIGS. 3 and 7 to the piston 6.
  • This drive movement takes place mainly via the rod 21 on the ball joint 53 to a connecting bridge 22, the structure of which is clearly shown in FIG Figures 4 and 5 can be seen.
  • This bridge 22 is fastened to the metering piston 6 by means of a screw 23, and the upper and zero positions of the piston 6 are shown in the figures.
  • a bearing bush 24 runs, which is fastened to the connecting bridge 22 and ensures the guidance thereof and thus the piston 6 parallel to the stationary main carrier.
  • the drain valve 5 with the spring 53 and the outlet connection 54 ' are attached to the outlet-side or lower end of the piston rod 6.
  • the annular pump piston 54 in the form of a rubber sleeve, the hollow configuration of the piston 6 also being visible.
  • the space 9 already described above is located in and above the piston, while the space 9 'is formed around the piston rod.
  • the cylinder 50 surrounds the piston rod 6.
  • the spring 53 'of the valve 4 is also supported at the top and presses it into the closed position, as shown.
  • the drive device will now be described with reference to FIGS. 3 and 7.
  • a main shaft 29 sits via a tongue and groove connection, the cam disk 28 is fastened, which in the illustration in FIG. 3 is shown raised from the cam roller 34 of the first lever 31 at a cleaning distance, because the first lever is in the position shown in solid lines 31 in the cleaning position.
  • the main shaft 29 is driven by a main motor, not shown.
  • the first lever 31 is mounted on the pivot shaft 30 and has a slot or is designed as a fork 44.
  • a swivel bearing device 33 is shown in the lower lever 31 on the lower left, to which a first air cylinder 32 is fastened, for example in order to move the first lever 31 along the double arrow 35 and to pull it to the left in the cleaning position for the position in FIG .
  • the cleaning position is additionally effected by the second air cylinder 46, as will be described later.
  • the first lever 31 interacts with the second lever 37, shown in solid lines, which is in the zero position. Its upper end is shown in dashed lines in the cleaning position. It can be imagined that a ball bearing 43 provides an operative connection between the levers 31 and 37, so that when the lever 31 is rotated about the pivot shaft 30, the second lever 37 pivots about its shaft 36.
  • the size of the stroke results from the leverage ratio h l : h 2 .
  • the slot 44 of the first lever 31 and a slot 38 in the second lever 37 are parallel to one another.
  • this Slot 38 is displaced via a threaded spindle 39, a nut 40 by rotating a drive wheel 41 'via an angular gear 42' and a flexible shaft 43 '(also flexible hose) when the spindle 39 is rotated.
  • the nut 40 can be moved in the direction of the double arrow 41 in the slot 38.
  • FIG. 7 The side view is shown in FIG. 7, the pins 42 being shown projecting laterally out of the nut 40.
  • a ball bearing 43 On this pin 42 is a ball bearing 43, which runs in the slot 44 of the first lever 31 and thus ensures the drive engagement.
  • the movement of the ball bearing 43 in the fork 44 in the first lever 31 thus results in the lever change h 1 : h 2 .
  • the adjustment in the zero position is provided so that when the nut 40 is moved in the direction of the threaded spindle 39 there is no movement of the connecting rod 21 and thus of the second lever 37. For this reason, the longitudinal extent of the fork 44 is exactly centered on the pivot shaft 30. As a result, there is no change in the zero position shown in FIG. H. the piston 6 remains in its highest position when readjustment is carried out.
  • a sensor (not shown in the figures) detects that no packing 10 is present under the outlet nozzle 54 'in operation and consequently product must not leak, then actuation of the air cylinder 32 can ensure that a pumping movement is not possible.
  • the air supply is switched from the left side of the piston 32 'in FIG. 3 of the air cylinder 32 to the right side.
  • the lever 31 and thus the follower roller 34 are brought into the zero position.
  • the trailing roller 34 lifts somewhat from the curve 28. Then the levers 31 and 37 and consequently also the drive connecting rod 21 stop.
  • the piston 6 must be brought into a completely different stroke position, as shown in FIG. 1. This is achieved in that, in the cleaning position, the cam disc 28 is first stopped, if possible in the position shown in FIG. 3, so that the cleaning distance as shown between the trailing roller 34 and the cam surface 28 results.
  • the above-mentioned second air cylinder 46 sits above a lever 48 on an eccentric shaft 47.
  • the two air cylinders 32 are in turn fastened on the lever 48, one cylinder for each unit i or j.
  • the eccentric shaft 47 By pivoting the eccentric shaft 47 according to FIG. 3 to the left rear in the direction of arrow 49, the air cylinder 32 is correspondingly withdrawn to the left in the direction of arrow 49 '.
  • the cam roller 34 is pulled further to the left in the direction of the left part of the double arrow 35.
  • the second lever 37 is pulled upwards into the cleaning position shown in broken lines.
  • the device works in such a way that when the pumping piston 54 is sucked in, the piston rod 6 is moved downward, as a result of which liquid 9 is sucked in, increasing the space.
  • the sprung inlet valve is open, while the drain valve 5 is closed. After the space 9 has been completely filled, the stroke is reversed, the inlet valve 9 is closed, the drain valve 5 is opened, and the filling begins.
  • FIG. 2 four different operating positions are shown.
  • the first position I the filling has just started.
  • the lower, outlet-side end 54 "of the outlet connector 54 ' is located a small distance above the liquid level (FIG. 1).
  • the position 11 is shown in which the outlet-side end 54" of the outlet connector 54' is already around is a little further away from the now higher liquid level (2).
  • this distance from the liquid level (3) in the package 10 has increased further, and finally in the end position IV the distance between the end 54 "in question and the liquid level (4) is greatest, namely the The area 10 'on the top of the packaging 10 with the embossing and folding lines is both free of liquid and of the outlet nozzle.
  • the setting of the corresponding movement in order to provide the increasing distance considered depends on the ratio of the base diameter of the packaging and the piston or the piston rod at the top and the height of the packaging.
  • the height and the base area of the packaging are therefore a prerequisite for determining the Piston rod diameter.
  • a different piston rod should preferably be used for each type of packaging.
  • FIG. 8 If liquids with larger viscosities or with pulp or the like are to be filled, the other embodiment according to FIG. 8 is preferably used. Identical parts in FIGS. 4 and 8 are provided with the same reference numbers or are not specifically designated. The differences with the particular embodiment are described below. Cutable additives in liquids can be processed with the filler according to FIG. 8, because the valves 4 and 8 are no longer spring-loaded as in the first embodiment according to FIG. 4 but are controlled pneumatically.
  • the valve housing 60 on which a carrier 61 for an air cylinder 62 is located, is flanged to the pump cylinder 50. This air cylinder 62 moves via the connection 63 the valve body 64, which can also be called the upper inlet valve body. The uppermost position is shown in FIG. In this, the inlet valve 4 is open.
  • the cutting edge 65 and 68 can be seen both on the valve 4 and on the drain valve 5.
  • a valve rod 67 which has two recesses 71 or 71 ′ or 71 ′′ in the stroke distance from one another in its upper region, creates the connection from the air cylinder 62 to the drain valve 5.
  • This connection is achieved via a clutch which has a clutch cylinder 70 with a piston rod 70a. These are located in the area of connection 63, with all stationary parts, e.g. B. the valve housing 60 and the holder of the air cylinder 62 are supported on the carrier 61.
  • the sharp-edged configuration of the drain valve 5 is shown with the valve edge 69, which cooperates with the cutting edge 68 on the outlet connection 54 '.
  • its lower end is not equipped with a sieve but with a cross bar 80, because even cut pulp could not pass through the sieve.
  • the device thus constructed works in such a way that, when the valves 4 and 5 move synchronously with one another, the air cylinders 62 and 70 are controlled in a certain manner.
  • the air cylinder 62 moves the upper inlet valve body 64 with the permanently coupled valve rod 67 (this keeps the inlet valve 4 open) downward from the position shown in FIG. 8 until the outlet end of the outlet connection 54 ′ is tight has reached the bottom of the package to be filled.
  • the space 9 has filled up because the inlet valve 4 has remained open and the drain valve 5 has remained closed.
  • the air cylinder 62 is actuated, which moves the upper inlet valve body 64 downwards, together with the valve rod 67, whereby the inlet valve 4 is closed and the drain valve 5 is opened. Now the upward stroke of the piston 6 begins and the ejection of the liquid mixed with pulp.
  • the above-mentioned cross bar 80 serves to limit the valve rod 67 (when it moves downward).
  • the drain valve 5 is opened to the maximum, and in this state the piston 6 moves its stroke fully up to the position shown in Figure 8. Since the valve rod 67 also moves upward together with the piston 6, the recess 71 is moved upward again from the dashed position 71 ′ into the middle position 71.
  • the clutch cylinder 70 closes again and the air cylinder 62 is pulled back into its upper position shown.
  • the piston 6 according to FIG. 4 has only one sliding guide in the cylinder 50 above the annular pump piston 54. In the lower area, the piston 6 has no guidance in the cylinder 50. This is pulled out here over the connecting bridge 22 and the bearing bush 24 onto the stationary guide rod 25.
