Description

Tank treatment machine and method for operating a

Container handling machine

The invention relates to a container treatment machine according to

The preamble of claim 1 and to a method according to the preamble

Claim 12.

Container treatment machines are known in different designs, in particular as machines of rotating design with a variety of

Treatment positions on a revolving transport element or rotor, each treatment position then u.a. a treatment head and a

Container carrier has. At a transfer position, the containers to be treated from an outer conveyor individually to a

Treatment items forwarded. At a further transfer position, the treated containers are removed from the treatment positions. Depending on the type of treatment of the containers and / or depending on the type and / or design of the treatment positions, a vertical relative movement between the respective treatment head and the container carrier of the treatment positions is often required, between a receiving and / or transfer state in which the respective container carrier is lowered and has an increased distance from the treatment head, and a

Treatment state in which the respective container carrier is approximated to the treatment head, so that the container held on the container carrier, for example, in sealing position against the treatment head rests and / or a probe-like

Section of the treatment head extends into the container interior,

for example in the form of a filling tube, in the form of a filling height determining tube or probe-like element, in the form of a tube for introducing or blowing a cleaning and / or disinfecting and / or flushing medium, etc. In known container treatment machines, the relative movement between the treatment head and Container carrier, ie the lifting movement of the

Container carrier often by raising and lowering the container carrier, each with a lifting member which has an actuator, for example in the form of a lifting cylinder or a linear drive. Every treatment position at the circulating transport element or rotor is then assigned its own such lifting member, with the fundamental advantage that while avoiding expensive lifting or cams and wear-prone cam rollers in a compact design, a quick lifting and lowering the container carrier is possible.

The invention has for its object to provide a container treatment machine, which while maintaining the basic advantages of a lifting or cams avoiding control of the lifting movement of the container carrier is characterized by a simplified structural design. To solve this problem, a container treatment machine according to the patent claim 1 is formed. A method for operating a container treatment machine is the subject of claim 12.

In the container treatment machine according to the invention is in only one

Transfer position at which the container to be treated to the

Treatment positions forwarded and also the treated containers are removed from the treatment positions, for the lifting movement of the

Container carriers of the treatment positions only a single lifting element with drive element or actuator stationary, e.g. provided on the machine frame.

With two transfer positions, one of which preferably serves to transfer the containers to be treated to the treatment positions and the other preferably to remove the treated containers from the treatment positions, only two lifting members common to all treatment positions are provided for the lifting movement of the container carriers of the treatment positions.

The training is continued to be made so that the driving connection between the container carrier each treatment position and the lifting member is only then or made by, if or that concerned

Treatment position due to the movement of the transport element or rotor enters the transfer position, and this driving connection is then automatically solved by the fact that concerned

Treatment position moved out of that transfer position at which the treated containers are removed from the container treatment positions.

For this purpose, the lifting member is formed for example with a coupling piece, which comes to produce the driving connection by the movement of the transport element into engagement with a coupling piece on the container carrier and to solve the driving connection by the movement of the

Transport element of the coupling piece of the lifting member is removed again.

"Container" are in the context of the invention in particular cans, bottles, kegs, tubes, pouches, each made of metal, glass and / or plastic, but also other packaging, especially those suitable for filling powdery, granular, liquid or viscous products are.

For the purposes of the invention, transfer device is generally to be understood as meaning a device with which the containers to be treated are individually transferred from an external conveyor to the treatment positions formed on the circulating transport element and / or the containers treated

Removed treatment positions and to an external conveyor

to get redirected. In the simplest case, the corresponding transfer element is formed by a transport star.

In sealing position with the treatment head befindlicher container means in the context of the invention that the respective container in the manner known to the expert with its container mouth pressed tightly against the treatment head. The term "substantially" or "approximately" or "approx." Means in the sense of

Deviation from the respective exact value by +/- 10%, preferably by +/- 5% and / or deviations in the form of insignificant for the function

Changes. In a development of the invention, the container treatment machine is designed for example in such a way that

that a single transfer element is provided which is suitable both for the transfer of the containers to the treatment positions, as well as for the

Decreasing the containers from the treatment positions, and or

that the transport element is driven clocked,

and or

in the case of a single transfer position, at which both the removal of the treated containers from the treatment positions and the transfer of the containers to be treated to the treatment positions take place, only one stationary lifting member is provided,

and or

that at two separate transfer positions for the transfer of the containers to be treated to the treatment positions and for the removal of the treated containers from the treatment positions both

Transfer positions a common lifting member or each transfer position is assigned its own, stationary lifting member,

and or

that the at least one stationary lifting member on the at least one

Transfer position is provided

and or

that at each treatment position a locking device for

Locking of the treatment head and / or the container carrier is provided in a raised position by the lifting member,

and or

that a driving connection between the at least one lifting member and the treatment head or the container carrier each

Treatment position exclusively or substantially exclusively exists when the treatment position at the at least one

In this case, all described and / or illustrated features alone or in any combination, in principle, the subject of the invention, regardless of their summary in the claims or their

Dependency. Also, the content of the claims is made an integral part of the description.

The invention will be explained in more detail below with reference to the figures of exemplary embodiments. 1 shows a simplified schematic representation and a top view of a

Container treatment machine according to the invention with a rotating transport element designed as a rotor and with a plurality of treatment positions on the rotor; FIGS. 2 and 3 show one of the treatment positions of the container treatment machine of FIG. 1 in different operating states; FIGS.

FIGS. 4 and 5 representations similar to FIGS. 2 and 3 in another

Embodiment of the container treatment machine according to the invention; Fig. 6 is a representation like Fig. 1 in a further embodiment of the container treatment machine according to the invention. The container treatment machine, generally designated 1 in FIGS. 1-3, is used to treat containers 2, which are shown by way of example as bottles, and comprises a circumferentially drivable transport element in the form of a rotor 4 which can be driven around a vertical machine axis (arrow A) and at its end Circumference is offset at equal angular intervals (pitch) about the vertical axis of the machine and at the same radial distance from it

Machine axis multiple treatment positions 3 are formed. These have according to FIGS. 2 and 3 each have a treatment head 5 and a

Container carrier 6, on which the respective container 2 to be treated is held suspended from a mouth flange 2.1. The rotor 4 is driven stepwise or clocked in the illustrated embodiment.

With the container carrier 6 is the respective container 2 for the treatment in the vertical direction from a lower receiving and transfer level (Fig. 2) on a

Treatment level (Fig. 3) can be raised, in which a probe or tube-like section 5.1 of the treatment head 5 extends through the upper container opening into the container interior and / or the container is arranged with an opening edge of its container opening in sealing position on the treatment head 4.

If the treatment machine 1 is designed, for example, as a filling machine, the treatment positions 3 are filling positions with filling elements formed by the treatment heads 5.

After the treatment, each container 2 is lowered again with the container carrier 6 to the receiving and transfer level. Each container carrier 6 is attached to a lifting linkage 7, which is provided separately in the illustrated embodiment as well as the container carrier 6 for each treatment position.

The containers 2 to be treated are fed to the container treatment machine 1 via an external conveyor 8 (arrow B). The treated containers 2 are discharged from the container treatment machine 1 via an outer conveyor 9 (arrow C). In particular, when the containers 2 are arranged upright during feeding and discharging on a transport element (eg hinge belt chain), a common transport element can also be used for both conveyors 8 and 9.

For the transfer of the containers 2 to be treated by the transporter 8 to a respective treatment position 3 and for the removal of the treated

Container 2 from the treatment positions 3 and the transfer of these containers to the conveyor 9 is a common, i. both a container inlet and a container outlet forming transfer device 10 is provided, which is driven synchronously with the rotor 4. In the illustrated embodiment, the

Transfer device 10 formed by a transport star 11. This is about a vertical axis in the direction of arrow D, i. Driven in the same direction and synchronously clocked with the rotor 4, in such a way that in each rest or

Standstill phase of the clocked movement of the rotor 4 at a transfer position 12 between the rotor 4 and the star wheel 11 in a first working cycle of the transfer device 10, a treated container 2 of a present at the transfer position 12 treatment position 3 removed and in a second working cycle of the transfer device 10 to be treated Container 2 to the at the

Transfer position 12 is still present treatment position 3 or to which there is still on the receiving and transfer level container carrier 6 passed. The transport star 11 is for this purpose formed with container receptacles 11.1, which is arranged at uniform angular intervals about the vertical axis of rotation of this star offset on a pitch circle which intersects or touches the pitch circle 4.1 at least in its vertical projection on which the

Container carrier 6 are arranged or move. In the rest or

Standstill phase of the clocked movement of the rotor 4 performs the transport star 11 between the first and the second working cycle of the transfer device 10 a the distance of two container receptacles 11.1 corresponding rotation step.

For the treatment of the container 2 in this embodiment, almost the entire angular range of only slightly less than 360 ° of the rotational movement of the rotor 4 is available. The peculiarity of the container treatment machine 1 is that for lifting and lowering the container carrier 6 only one lifting member 13 is provided and also required, which is stationary, ie neither with the rotor 4, nor with the transport star 11 circumferentially provided at the transfer position 12.

2 and 3, this lifting member is shown for simplicity as a lifting cylinder 14, for example, is pneumatically actuated and the piston rod 14.1 vertically and at a transfer position 12 located at the treatment position 3, for example, coaxially or substantially coaxially with the local lifting linkage. 7 is arranged, which according to the

Double arrow E axially displaceable on the rotor 4 is mounted. At its lower end, the piston rod 14.1, for example, with a

extended head 15 is formed, which cooperates with a coupling piece 16 which is provided at the upper end of each lifting linkage 7. The connection between the coupling piece 16 and that of this coupling piece

positively received or engaged behind head 15 is made solely by the rotational movement of the rotor 4, i. always if one

Treatment position 3 reaches the transfer position 12, pushes the respective coupling piece 16 on the head 15 of the stationary lifting member 13, so that the container carrier 6 in question then with the lifting member 13 for delivering a treated container 2 from the upper treatment level in the lower

Recording and transfer level lowered or after receiving a container to be treated 2 from the intake and transfer level on the

Treatment level can be raised controlled.

The coupling piece 15 is for example designed as a C-profile, which is open on both sides with respect to the direction of rotation of the rotor 4. Each container treatment position further comprises a locking device 17, which is controllable such that it locks after raising the container support 6 to the treatment level this at the treatment level and the container support 6 releases for lowering to the receiving and transfer level. Figs. 4 and 5 show in views similar to Figs. 2 and 3 as another

Embodiment a container treatment position 3a, which is provided together with a plurality of similar treatment positions 3a instead of the treatment positions 3 on the rotor 4. The treatment position 3a essentially differs from the treatment position 3 only in that the container carriers designated by 6a are designed such that the containers 2 stand up on the container carriers 6a with their container bottom. FIG. 6 shows in a schematic representation as in FIG. 1 a

Container treatment machine 1a, which differs from the container treatment machine 1 essentially only in that in turn of a

Transport star 11a formed transfer device 10a, which serves for transferring the container to be treated 2 each individually to a treatment position 3 and the decrease of the treated container 2 from the respective treatment position 3, two transfer positions 12a and 12b, based on the direction of rotation D of Transport star 1 1a on the outer conveyor 8 following the transfer position 12a for transferring a respective container 2 to a

Treatment position 3 and following this, the transfer position 12b to

In order to achieve this, the container receptacles 11 a.1 of the transport star 1 1 are arranged on a pitch circle, at least in the vertical projection the pitch circle, 4.1 on the treatment positions 3 and their container carrier 6, 6a

are arranged at the transfer positions 12a and 12b cuts. Furthermore, the pitch of the container receptacles 1 a.1 equal to the pitch of the treatment positions 3. In the processing machine 1 a at each transfer position 12a and 12b respectively a lifting element or lifting member 13 is provided stationary, namely at the transfer position 12a for lifting the respective container carrier 6 or 6a from the admission and transfer level to the

Level of treatment and at the transfer position 12b for lowering the respective container support 6 or 6a from the treatment level to the receiving and transfer level. Also in the container treatment machine 1 a, the rotor 4 and the transport star 11a are in turn clocked and driven synchronously. For the

Treatment of the container 2 is almost the entire angular range of

Rotary movement of the rotor 4 between the transfer position 12a and the

Transfer position 12b available.

The described container treatment machines 1 and 1a are characterized by a reduced design volume by a reduction of the design effort, in particular due to the fact that for the container inlet and the container outlet a common transfer element 10 or 10a in the form of a single transport star 1 1 and 1 respectively 1a is provided, and that for raising and lowering of the container carrier 6 and 6a only one lifting member or only two lifting members 13 are required, each stationary at a

Machine arranged. The respective lifting member 13 has a

Lifting motion generating stationary drive or actuator.

It has been assumed above that the drive of the stationary lifting member 13 is a lifting cylinder 14. Other drives or actuators are possible, such as electric linear drives, etc.

The invention has been described above by means of exemplary embodiments. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.

So it was assumed above that for the required

Relative movement between the respective treatment head and the associated container carrier 6 and 6a latter is raised and lowered. In principle, but instead of the respective treatment head 5 could be raised and lowered, and then between an upper receiving and

Transfer level for the transfer and acceptance of a container from the

Treatment position 3 and a lower treatment level during the

Treatment of the respective container 2. Also in this embodiment takes place in the case of a single transfer position 12, the raising and lowering the Treatment heads 5 at this transfer position with a single, stationary lifting member or in the case of two separate transfer positions 12a and 12b, for example with two stationary lifting members 13. However, embodiments of the container handling machine are possible in which two transfer positions 12a and 12b for the transfer of Container to the treatment positions or for the removal of the container from the

Treatment positions only a stationary lifting member 13 is provided with which the required relative movement between the respective treatment head and the container carrier 6 and 6a is generated.

In the figures and the above description, it has been assumed that a separate, individually controllable lock 17 is provided for each treatment position, which is arranged by design on the rotor 4 and is and rotates with this. However, according to the invention is also such

Lock provided, which is stationary and not running around and is provided for all container carrier 6, 6a. More in detail, this lock 17, for example, on a stationary, the rotor 4 almost completely enclosing, annular, sheet-like element. This element is not present at the transfer positions 2 or 12a, 12b. Is a container carrier 6 or 6a on the

required level of treatment is raised, and has the rotor 4 of the

For example, the element and the container carrier 6, 6a enter into an operative connection, so that the container carrier 6, 6a also remains spatially at the treatment level when the latter

Area of action of the stationary lifting member 13 has already left again.

For example, the sheet-like element could engage in a groove provided on the container supports 6, 6a.

On the graphic representation of this embodiment has been omitted.

Furthermore, it has heretofore been assumed that the present invention finds application in filling processes in which the container is in sealing position with the filling element. This is not mandatory. According to the invention It is likewise provided that the present invention is also used in the case of free-jet filling methods, in which case the container is not in sealing position with, but at a distance from the filling valve. The change of the filling process requires no modifications relevant to the invention, so that it is possible to dispense with the presentation of the necessary modifications - which are familiar to the person skilled in the art in any case.
