Description

Container cleaning module for a modular container cleaning machine and method of operating the same

Technical Field

The invention relates to a container cleaning module for a modular container cleaning machine and a method for operating a container cleaning module.

Background

In known container processors, very long exposure times, for example in an alkaline bath, are required to ensure the desired cleaning and removal of the label from the container. For this purpose, the containers arranged in the container basket are driven by the chain through the different alkaline baths and are subsequently cooled by the liquid discharged through the spray nozzles, removing the residues of the alkaline liquor. The required container cleaners are of a large size due to the long exposure time required and the large amount of containers to be cleaned, and the length of such container cleaners is also long. The container basket employed is typically a compromise between different container sizes.

The control means may be implemented as a central controller or as a plurality of decentralized controllers.

At least one liquid outlet of the module housing can be opened and closed by triggering. The separated dirt may be discharged through the liquid outlet. A separate outlet for discharging dirt may be provided.

At least one liquid inlet of the module housing can be opened and closed by triggering.

In one rack, the same or different containers may be configured. Containers such as PET containers or glass containers having a weight below a predetermined weight may be fixed in the holder.

Controlling and monitoring the cleaning operation by the container cleaning module may include one or more of the following non-exhaustive aspects:

-controlling and monitoring the temperature of the liquid in the container cleaning module for the cleaning operation or used during the cleaning operation. Wherein the level of temperature takes into account the (average) contamination level of the container to be cleaned and/or the type of container (type of material (glass, plastic container) and/or thickness of material), and/or the amount of liquid applied, and/or whether the liquid is discharged, for example through a nozzle, and/or whether the liquid can be controlled and monitored to overflow the interior of the container cleaning module. The degree of contamination may be preset manually or may be determined by sensors and/or by information from a system comprising the container cleaning module.

Control and monitoring of the pressure of the liquid, for example during discharge from the nozzle and/or in the supply system, and/or the amount of liquid used for or during the cleaning operation. Wherein the amount of liquid takes into account the (average) contamination level of the container to be cleaned and/or the type of container (type of material (glass, plastic container) and/or thickness of material), and/or the temperature of the liquid used, and/or whether the liquid is discharged, for example through a nozzle, and/or whether the liquid can be controlled and monitored to overflow the interior of the container cleaning module.

-controlling and monitoring the discharge of liquid for the cleaning operation or during the cleaning operation through the nozzle, and/or controlling and monitoring the discharge of liquid for the cleaning process or during the cleaning process for overflow of liquid inside the container cleaning module. During the cleaning operation, the discharging and the flooding through the nozzle may be performed sequentially. The overflow may be performed by discharging liquid from the nozzle and/or from the liquid inlet.

-controlling and monitoring the duration of the cleaning operation or part of the operation. This may include controlling and monitoring the cleaning operation and/or the total duration of the various sections thereof.

All of these or various aspects thereof may also be referred to as controlling and monitoring the cleaning operation of the container cleaning module as desired.

A modular container cleaning machine with a container cleaning module allows for adjusting the cleaning operation, for example, to correspond to a container arranged in a rack, without any time-consuming changes at the container cleaning module.

The modular container cleaning machine may comprise a plurality of container cleaning modules as described above and below. The plurality of container cleaning modules may include a common liquid supply line and liquid drain line. Multiple container cleaning modules may be operated independently, for example, to enable different cleaning operations to be performed in parallel (e.g., in the event of different liquid temperatures and/or durations of cleaning operations and/or discharge of liquid through nozzles and/or internal flooding of the container cleaning modules).

Two or more container cleaning modules may also be disposed adjacent to one another such that the rack may be transferred directly from one container cleaning module to an adjacent container cleaning module.

The first end of each pin may include one or more nozzles. For example, the cleaning of the interior of the container may be achieved by draining the liquid in the direction of the bottom of the container. For example, a plurality of nozzles may be provided along each pin. By providing a plurality of nozzles, the cleaning of the interior of the container can be improved. For example, each bracket may be provided with 40 to 60 pins.

The first end of each pin may have at maximum a first diameter corresponding to a container opening with which a container may be placed onto one of the pins, and wherein the second end of the pin may have a second diameter that may be 2% to 5% smaller than the first diameter. By this second diameter, there may be a distance between the pin and the container opening of the container placed on the pin. Thus, liquid that has been discharged and sprayed by the nozzle or nozzles of the pin may flow out, for example under the influence of gravity. During this process, possible impurities detached by internal spraying can also flow out and leave the container.

Each pin may comprise an inverted frusto-conical body. The first end of the inverted frusto-conical body may be designed to be convex. For example, liquid may thus flow out of the first end of the pin.

The respective at least one liquid supply line may be designed to direct liquid to one or more nozzles of the pin. The liquid may include lye, acid and/or water.

Each of the at least one stand may include an additional nozzle for the internal spray container. The additional nozzle may also be supplied with liquid via at least one liquid supply line.

Each of the at least one stent may comprise a stent tube. The bracket line may comprise a conduit connecting at least one liquid supply line, one or more nozzles of the pin, and optionally additional nozzles for liquid supply.

For example, the liquid supply line may be designed to be connectable with the bracket line. In one configuration in which the holder in the module housing is in operation, the liquid supply line of the holder may be designed to be connectable with the liquid inlet of the module housing.

Each of the at least one rack may include a plurality of compartments for receiving one or more containers. For example, at least one of the plurality of pins may be configured in each compartment. For example, one or more locking pins may be associated with each of the compartments.

The compartments may be arranged on a support as described above or below, for example by a form-fit or force-fit connection, or for example by a clamp element and/or a clamp connection. This combination of compartment and rack can be considered to be made up of two parts. The compartment may also be provided as a whole with a stand as described above or below.

The compartment may include horizontal supports and vertical supports. The support may be designed to support one or more containers configured in an inverted orientation in the compartment by the support.

The compartments may be designed and configured or may be configured with respect to the brackets or pins of the brackets such that one pin may be configured in one compartment. For such embodiments of compartments, brackets and pins, the dimensions of the container to be cleaned, the dimensions of the module housing, etc. may be considered.

Each of the at least one stent may have a length in the range of 1m to 2m and a width in the range of 1m to 1.5m, wherein for example the base of the at least one stent may be rectangular or square.

The module housing may have a length and a width respectively in the range of 2m to 5m and a height in the range between 0.4m and 4m, wherein for example the base of the module housing may be rectangular or square.

The bracket(s) and module housing and insertion device may be sized here to match the container cleaning module.

If at least two insertion devices are provided, these may be arranged adjacently and/or overlapping within the module housing. Correspondingly, two or more brackets may thus be arranged adjacently and/or overlapping within the module housing.

The module housing may include a nozzle located therein. These nozzles can be used for external cleaning of the container and/or for internal cleaning of the module housing. The rack disposed in the module housing may also be cleaned. For example, the nozzles may be provided at the side walls, at the bottom and/or at the cover of the module housing. Nozzles disposed in the cover may also be used for venting of the module housing during flooding. For example, the module housing may comprise an annular nozzle, which may be configured in the module housing such that the annular nozzle may be configured in an aligned manner above the pin when the at least one bracket is in the operational configuration.

In this and in the following, the arrangement in operation will be understood as having been introduced into the module housing and at least one openable access opening capable of being closed in a fluid-tight manner has been closed.

The liquid outlet may comprise a movable vane and/or a movable mesh. The blades and/or the mesh enable comminution of labels or label residues in the liquid to be discharged through the liquid outlet. For example, the movable blade and/or the movable mesh may be designed to be movable towards and away from a discharge channel in the liquid outlet. Therefore, the label or the label residue can be prevented from being stuck. For example, in the region of the discharge channel, cleaning nozzles for the movable vanes and/or the movable grid can be provided. Thus, the adhered label or label residue may be removed from the blade and/or mesh. For example, a multi-way valve may be provided downstream of the movable vane and/or the movable grid. Through the multi-way valve, the liquid discharged from the liquid outlet may be supplied to different lines, for example for reuse of the liquid, such as preheating of the liquid that may be supplied to the container cleaning module. In the region of the discharge channel, a removal device, for example an aspirator (extractor), can be provided for manually or automatically removing the separated dirt.

The at least one openable access opening that can be closed in a fluid-tight manner may be designed to be lockable in a fluid-tight manner at least two different positions by means of the at least one fitting and the at least one pivot. The fitting may be arranged at the frame of the module housing and the pivot may be arranged at the door of the module housing or vice versa. Since at least two different positions are provided for locking, a port that can be closed in a liquid-tight manner can be obtained. Thus, for example, when closing the access opening, the interior of the module housing may be filled with liquid without liquid leaking from the module housing.

The module housing may comprise two openable access openings that can be closed in a fluid-tight manner. For example, two openable ports that can be closed in a fluid-tight manner may be arranged on opposite sides of the module housing. Through these two ports, the introduction of the stent through a first one of the two ports may be allowed, and the removal of the stent through a second one of the two ports.

This may be expedient if a plurality of container cleaning modules are arranged one after the other in a modular container cleaning machine. A rack may be transferred from a first module housing of a first container cleaning module to a second module housing of a second container cleaning module, for example, to perform a further cleaning process there, or to perform a water rinse.

The sensing mechanism may include a detection and execution sensing mechanism. The detection sensing mechanism may detect the temperature of the liquid in the container cleaning module and/or the degree of contamination of the liquid discharged through the liquid outlet, etc. The execution sensing mechanism may initiate the execution based on and/or during the cleaning operation. For this purpose, for example, the execution sensor may use a value detected by the detection sensor, which may be obtained from the detection sensor, or which may be input into the detection sensor.

For example, the control device may be designed as a stored-program controller.

The container cleaning module may further comprise at least one drain pan to be arranged under the at least one stand. The drain pan may be placeable outside the module housing. After the cleaning operation, the rack with the cleaned containers can be arranged in an aligned manner over the drain pan. Thus, the liquid residue present may drip from the container, rack, pin and/or compartment into the drain pan and collect in the drain pan. The holder with the container to be cleaned, which means before the cleaning operation, can also be arranged in an aligned manner above the drain pan. For example, product residues (liquid and dry product residues) adhering in and/or at the container to be cleaned may be collected in a drain pan. The drain pan may have a size that may be designed to be as large as or larger or smaller than the bottom surface of the stand.

Furthermore, a method for operating a container cleaning module for a modular container cleaning machine as described above or below is provided.
