  • the invention relates to feeding devices according to the preamble of claim 1 and feeding methods according to the preamble of claim 11 . Furthermore, the invention relates to transport devices and cleaning arrangements, each of which has feed devices.
  • cleaning machines For the refilling of reusable containers, e.g. reusable bottles made of glass or PET, it is necessary for these containers to be cleaned before the filling process. Such cleaning takes place in cleaning machines, also referred to as cleaning devices in the claims. Such cleaning machines are known in the prior art in a variety of ways. Reference is made only as an example to the bottle cleaning machines from applicant KHS GmbH, which have been known under the name “INNOCLEAN” for many years and are state of the art. Insofar as the designation "container” is chosen uniformly below, this should mean in particular bottles, and in particular containers and bottles made of glass, PET or another material that allows reuse.
  • the containers to be cleaned are usually placed in so-called container cells and, received in these container cells, are guided through the cleaning machine from the entrance of the machine to the exit of the machine, in order to be fed to different treatment devices within the machine and to be subjected to different treatment steps.
  • the promotion of the container to such container cleaning machines is usually about T ransport wornen such. B. via infeed belts that transport the containers standing to the cleaning machine.
  • the present invention relates to such a feed device which, for example, is supplied with containers by a transport device on the input side and which transfers containers to the cleaning machine on the output side.
  • WO 2018/206381 A1 shows a cleaning machine for containers and shows examples of feeding devices, in particular in FIGS.
  • An essential element of this feeding device is a rotary and rotary-driven transfer device with transfer fingers.
  • This transfer device uses the transfer fingers to grip the bottom of the containers supplied in an upright position, lifts the containers and moves them along guide rails in the direction of the container cells of the cleaning machine, with the containers being transferred from the initially upright orientation to a horizontal orientation.
  • WO 2018/206381 A1 shows interrupting devices that completely prevent the further transport of containers when sensors detect that misaligned containers or gaps in the container flow exist. In particular, it is a matter of preventing containers lying flat from entering, as is shown, for example, in FIG. 4 of WO 2018/206381 A1.
  • the interrupting device is thus brought from a release position into a blocked position, namely when a misorientation is detected. Provision is made for a blocking element to move into the container flow from above and thereby block the path of movement and further movement the container prevents. After the incorrectly oriented container has been removed, the blocking element moves from the blocked position into the release position and the containers can pass through the interruption device.
  • Bottles conveyed on a conveyor are inspected for contamination and if contamination is detected, the bottle lock is placed in the locked position and blocks the flow of bottles on a conveyor.
  • the catch should spring out into the movement path at right angles to the movement direction of the bottles.
  • the blocking is event-dependent and the blocking is only lifted when the contaminated bottle has been removed.
  • WO 2021/078506 A1 from the applicant KHS GmbH shows a feeding device in FIG.
  • WO 2019/238314 A1 from the applicant KHS GmbH also shows an example of a feed device that is connected upstream of a cleaning machine. Explicit reference is made to Figures 1-3 of this WO 2019/238314 A1 and to the corresponding description for the further technical background of the present invention.
  • Feeding devices of this type are generally supplied with containers by an upstream transport device, with this transport device generally feeding these containers in a stream of containers to the input of the feeding device.
  • the feeding device has its own transport device in order to transport the received containers in a standing manner from the input of the feeding device to the output of the feeding device.
  • an endless belt is provided on which the containers stand, as for example in FIG. 3 of WO 2021/078506 A1 or shown in Figure 1 of WO 2019/238314 A1.
  • the container stream is then usually divided up into several parallel rows.
  • the containers then arrive in these several parallel rows to the transfer device, which, as explained above, is arranged to be rotatable and rotationally driven and has several transfer fingers.
  • the container in a row that is closest to the cleaning machine should be gripped on the bottom by the transfer finger of the transfer device assigned to the respective row.
  • the transfer finger lifts the container, transfers it from a standing to a lying orientation, usually by guiding the container along guide rails, and transfers the container to a container cell, which is already part of the cleaning machine.
  • a further object of the invention is to indicate a corresponding feeding method.
  • the feeding device has a transfer device for transferring the containers into the cleaning device. Furthermore, the feeding device has a transport device. This should be designed for the upright transport of containers in a conveying direction towards the transfer device. Corresponding transport devices for the upright transport of containers are known in a variety of ways in the prior art.
  • the feed device receives containers, for example from an upstream transport device, usually in a container stream. Only in the feed device is the container flow divided into several lanes through which one row of containers passes become.
  • the provision of several lanes permits higher throughput rates and is therefore the norm with the available feed devices, although the invention can also be implemented with only one lane.
  • the area of the feed device in which the containers are not yet guided in lanes can be referred to as the entry area, while the term transfer area means the area of the feed device in which the containers are guided in one row in one or more lanes.
  • the provision of multiple lanes is preferable to the provision of only one lane. For this reason, it is assumed and described below, without loss of generality, that several lanes are provided.
  • the invention also relates to the special case that only one aisle is provided.
  • the multiple lanes run parallel to each other.
  • the containers are guided in a single row from an aisle entrance to an aisle exit.
  • the feed force for the containers is provided by the transport device of the feed device on which the containers stand, and the lanes are delimited laterally and thus spatially defined by a plurality of lane walls running parallel to one another.
  • the distance between opposing aisle walls laterally delimiting an aisle defines the maximum diameter of the containers that can pass through the aisle in a single row.
  • the containers are guided to a transfer device which is arranged on the lane exit side of the transfer area.
  • the function of the transfer device is to transfer the containers to a downstream cleaning device.
  • the transfer device is designed to be rotatable and rotary-driven about a horizontally aligned axis of rotation. When the transfer device is operated as intended, a rotary drive ensures that rotation takes place about a horizontal axis of rotation.
  • the transfer device also has to carry out its transfer function several transfer fingers, which are arranged radially on the outside of the transfer device.
  • the arrangement of the transfer fingers (or conversely, the arrangement of the lanes) is such that each lane is assigned at least one transfer finger, which means that containers guided in the respective lane can interact with the transfer finger in the manner desired for the transfer . If there are a number of lanes, the transfer device has a number of transfer fingers spaced apart from one another in the axial direction.
  • the transfer device also has a plurality of transfer fingers in the circumferential direction, e.g. on opposite sides of the transfer device, as a result of which a transfer finger can carry out a transfer process for every half revolution of the transfer device.
  • a transfer device In order to achieve a specific throughput, such a transfer device must therefore rotate at half the rotational frequency compared to a transfer device in which only one transfer finger would be provided in the circumferential direction.
  • the provision of a plurality of transfer fingers in the circumferential direction is also advantageous for reasons of smooth circulation, since in this way a transfer device constructed symmetrically to the axis of rotation is created. This is therefore considered an optional and advantageous embodiment.
  • a blocking element should be arranged in the transfer area in each aisle, which blocking element can interrupt the flow of containers to the associated transfer finger by being brought from a release position into a blocking position.
  • This can e.g. B. be realized in that a structurally separate from the other blocking elements blocking element is arranged in each alley.
  • this can also be implemented by a single component that forms the blocking element in all aisles, ie, for example, a blocking barrier that extends over all aisles. Intermediate forms are also possible, for example several partial barriers extending over several aisles.
  • Such locking elements are known in the prior art in the general form described so far.
  • these known blocking elements work in an event-dependent manner, as was explained at the outset with regard to the prior art, in order to interrupt the inflow of containers in the event of a malfunction so that a malfunction can be remedied.
  • the blocking element according to the invention differs from this in that the blocking element is driven to switch periodically between the blocking position and the release position, the periodicity being set coupled to the rotational speed of the transfer device.
  • the periodic change between the blocking position and the release position and the coupling of the periodicity to the rotational speed of the transfer device enables the container stream to be blocked and released in a lane to the transfer finger in time with the transfer process carried out by the transfer device.
  • the blocking element is in the blocking position when the transfer finger touches the bottom of the container at the beginning of the transfer process, because at this point in time the pressure of following containers is reduced by the blocking element.
  • the blocking element can, for example, switch to the release position and This enables the subsequent flow of containers again, so that at this point in time a follow-up pressure is created again and the next container is reliably brought into a position in which a transfer finger can act on the container again. Therefore, the frequency with which the blocking element changes between its blocking position and its release position preferably corresponds to the frequency with which transfer fingers transfer containers from a lane into a cleaning device. If, for example, there is a transfer device with two transfer fingers in the circumferential direction and this transfer device rotates at a certain frequency, the locking element changes between the locked position and the release position at twice the frequency, since the transfer device performs two transfer processes per complete rotation.
  • the coupling of the periodicity to the rotational speed of the transfer device, and therefore to the rotational periodicity of the transfer device can be provided, for example, by a synchronization implemented in terms of control technology, for example by synchronization between the control of the drive for the transfer device and a drive for the blocking element.
  • synchronization means initially only a synchronous maintenance in the periodicity: an increase or decrease in the rotational speed of the transfer device should result in a corresponding increase or decrease in the periodicity of the change of the blocking element between the blocking position and the release position.
  • this synchronization can optionally and advantageously also include the synchronization of the change times, i.e. not only in the change frequency, i.e.
  • the blocking element According to the invention, it is only necessary for the blocking element to be periodically moved into a blocking position and periodically returned to a release position. It would be possible, for example, to design such a blocking element as a hydraulically or pneumatically expandable element which, in the expanded state, protrudes into the path of movement of the containers in an aisle or, in the expanded state, presses a blocking element into the path of movement, and to periodically expand this element by means of pneumatic or hydraulic pressure and returned to the release state by passive or active removal of the pneumatic or hydraulic pressure medium. Examples of this are given in the later drawing descriptions.
  • the blocking element it is considered to be technically advantageous and preferred for the blocking element to be actuated mechanically and for this purpose to be mechanically connected to a drive and to be moved mechanically between the blocking position and the release position.
  • This allows precise and fast movements with a space-saving and simple design at the same time.
  • this opens up the advantageous possibility of providing a mechanical coupling to drives already present in the feed device, for example to a drive of the transfer device or to a drive of the transport device.
  • an independent drive can also be provided for the blocking element, which, for example, facilitates retrofitting.
  • this blocking element Since the technical purpose of this blocking element is to reduce the tracking pressure exerted by the containers that follow in a defined and desired manner, it is advantageously provided that it is arranged close to the area in which the transfer fingers engage with the containers. If the blocking element were to be arranged at a distance from this engagement area, for example in the entry area of the feed device, a large number of containers would continue to move up and down behind the container to be transferred. The arrangement close to the engagement area means that only a few containers are pressed during the execution of the transfer process.
  • close to the engagement area means that the distance between the locking engagement site of the locking element and the engagement area of the transfer finger is less than five times the size of the aisle width, preferably less than three times the size, more preferably that only one container behind the locking element is arranged in the locked position in the engagement area.
  • the lanes preferably and advantageously initially run in a straight line from their lane entrance to the lane outlet in a first conveying direction, then pivot laterally by a deflection angle to a second conveying direction.
  • This deflection angle is selected to be between 15 and 30 degrees, for example.
  • the alley then pivots back to the original conveying direction, as a result of which the containers as a whole are offset laterally. This is done because there is usually one circulating transport device per aisle, for example a conveyor belt. Before pivoting, the containers are usually in the middle of this conveyor belt associated with the aisle; after the lateral displacement, the containers should then be acted upon in equal parts by two adjacent conveyor belts. A small gap is left between the adjacent belts through which the transfer finger can access the container.
  • the containers guided in the aisles carry out in this deflection area a change of direction from a first to a second conveying direction and back to the first conveying direction, with the blocking element preferably being arranged in this deflection area.
  • This arrangement is preferred because in this area a small movement of a blocking element is sufficient to create a bottleneck blocking the container flow.
  • this area is also close to the point of contact of the transfer finger.
  • Such an arrangement in this deflection area of the blocking element already exists when the blocking element in its release position and/or in its blocking position protrudes at least partially into the deflection area.
  • a preferred and advantageous embodiment of a blocking element is that it is designed as an end piece of a linearly displaceable rail, which is arranged to be driven in a linear movement in the first conveying direction.
  • This rail can, for example, preferably lie snugly against the aisle wall or even be embedded in the aisle wall, as a result of which the free cross-section in the aisle that is available for the containers is hardly reduced or not reduced at all.
  • the rail is preferably displaced in the first conveying direction in such a way that the rail end piece of the blocking rail protrudes into the aisle in its blocking position in the deflection area, resulting in a bottleneck in the aisle that the following containers cannot pass through.
  • the barrier rail follows the course of the aisle wall.
  • the rail could therefore have an overall straight course and be arranged in the area in which the aisle walls have their straight course.
  • the rail like the alley, could have an angled section, with this angled section being in the deflection area the alley is arranged. Further details on embodiments according to the invention result from the exemplary embodiments shown in the figures.
  • the feed device has vibrating fingers in its entry area, namely in the area of the aisle entry.
  • a vibrating finger is understood in the art to mean a movable element which is arranged in the inlet area of the lanes, usually lying in the extension of the lane walls, in order to prevent containers from blocking one another when entering the lane. Due to the movement of the shaker finger, such a jam is broken because the geometric and power stalls are broken.
  • This vibrating finger preferably performs a vibrating movement coupled to the movement of the blocking element.
  • the coupling can be a mechanical coupling, for example.
  • a linearly displaceable rail is provided as the blocking element, it is preferred that the end of the rail on the aisle entrance side forms this vibrating finger.
  • this rail must, for example, have a sufficient length to protrude into the aisle entrance and preferably overhang the aisle wall.
