Description

DESCRIPTION

Bottle cleaning machine for cleaning bottles

The present invention relates to a bottle cleaning machine for cleaning bottles in the beverage processing industry according to independent claim 1 and independent claim 6.

State of the art

Bottle cleaning machines, which are used particularly in the field of the beverage processing industry, are generally known.

Until now, operators are often employed to take over bottle cleaning machine activities, such as discarding dropped bottles. Likewise, operators also have to take charge of additional activities in relation to the waste produced. This leads to very monotonous work, which also makes processes more prone to errors. Additionally, well-trained, and therefore expensive, personnel may be required to perform these tasks. An example of a machine of this type is known from document DE 2011 0686 U.

Aim

Starting from the state of the art known up to now, the technical objective to be solved is, therefore, to simplify the handling of bottle cleaning machines and reduce the effort of operators in normal operation.

Solution

This object is achieved by the bottle cleaning machine for cleaning bottles according to independent claim 1 and the bottle cleaning machine for cleaning bottles according to independent claim 5. Advantageous developments of the invention are included in the dependent claims.

According to the invention, the bottle cleaning machine for cleaning bottles in the beverage processing industry comprises transport equipment for the upright unordered transportation of bottles in a mass flow to an inlet zone of the bottle cleaning machine. , a detection equipment for detecting a defective and/or fallen bottle being arranged in or in front of the entrance area and a robotic arm with a gripping element being arranged in the entrance area, being able to receive a machine control unit bottle cleaner information about a defective and/or fallen bottle from the detection equipment and being able to control the robotic arm to straighten the defective and/or fallen bottle or to remove it from the transport equipment. In this regard, the inlet area of the bottle cleaning machine is to be understood as any area of the transport equipment in which the bottles are transported in an unordered manner, but at least in the form of a mass flow, and from which they are transferred. finally to a cleaning area of the bottle cleaning machine, in which they are cleaned.

The use of a robotic arm in combination with detection equipment and a suitable control unit allows the activities of discarding defective or dropped bottles otherwise carried out by the operator to be carried out in an automated manner, so that the operator no longer only He is in charge of supervision at most, having to intervene personally only on rare occasions. At the same time, reliability can be increased, since the error-proneness of a monotonous activity can be significantly reduced by computer-aided and automated processes.

The detection equipment comprises a camera which is arranged above the transport equipment and whose optical axis runs perpendicular to a transport plane defined by the transport equipment, in which the bottles are transported. In this way, dropped or defective bottles can be prevented from being covered by bottles next to them, which improves the detection accuracy of these bottles.

It may be provided that the robotic arm comprises at least two joints and/or that the action zone of the robotic arm extends over the entire width of the transport equipment. In this way, the robotic arm can carry out all the handling of all the bottles that have fallen or are defective in the transport equipment.

Furthermore, it may be provided that the robotic arm is fixed on a support, the support being arranged next to or above the transport path. Therefore, high accessibility, ideally of all bottles in the transport equipment, is possible.

In one embodiment, the control unit is configured to control the robotic arm, remove a defective bottle from the transport equipment, and straighten a fallen non-defective bottle and maintain it in the transport equipment. In this way, work cycles can be reduced, since a defective bottle, regardless of whether it has fallen or is still upright, should be removed from the transport equipment and should not be fed to the cleaning area. Thanks to this, at least for bottles that have been dropped and are defective at the same time, the work step of straightening them can be omitted, which in any case could fail due to deterioration.

The other bottle cleaning machine according to the invention for cleaning bottles in the beverage processing industry comprises a transport equipment for the upright unordered transport of bottles in a mass flow to an inlet zone of the bottle cleaning machine. , a collection container for discarded bottles being assigned to the bottle cleaning machine, comprising a fill level sensor, the collection container being configured to emit a signal indicating the fill level when a predefined fill level is reached. Thanks to this bottle cleaning machine and in particular the collecting container, the operator is exempt from having to constantly monitor the filling level of the collecting container. Therefore, you can dedicate yourself to more important and different activities. Additionally, this signal can be used by other systems to initiate other automated processes.

In one embodiment, the signal is an acoustic, optical or electronic signal. Operators can easily perceive acoustic or optical signals, so that an operator can be informed as effectively as possible when the predefined filling level has been reached and can initiate, if necessary, additional steps, such as manual emptying. of the collecting container. An electronic signal, transmitted for example via a data line, allows other components to be controlled based on this signal.

Furthermore, it can be provided that the filling level sensor is configured as a scale. In particular, when stacking objects such as bottles with a very irregular shape, a fill level sensor, which measures the actual stacking height of the bottles, can be a disadvantage, since it does not take into account gaps or irregularities in the stacking of the bottles. bottles. In this case, the use of a scale is advantageous, since it only measures the mass or weight of the bottles, regardless of their arrangement in the collecting container.

In another embodiment, the collecting container is configured as an autonomous mobile cart that, depending on the signal, can move to an emptying station, transfer the bottles thereto and return to the bottle cleaning machine. In this way, the operator can be completely exempt from having to deal with emptying the collection container, which prevents accidental overloading of the collection container and thanks to this the falling of bottles that are attached to it, and improves the reliability of emptying the collection container. collecting container.

In a further development of this embodiment, at least two collection containers are assigned to the bottle cleaning machine, the collection containers being able to automatically control their movement in such a way that at all times a collection container is positioned to receive discarded bottles. The positioning of the collecting container "for receiving discarded bottles" is to be understood in this regard in such a way that the collecting container is arranged in the area provided for this near the bottle cleaning machine, so that the bottles can be brought into the container. collector, for example, by an operator or a robotic arm provided for this purpose. The respectively other collection container may be in a waiting position in a "waiting queue" in the usual direction of movement of the collection container behind the collection container currently positioned to receive the bottles or may be, for example, in the return movement to the emptying station or bottle cleaning machine. In this case, other intermediate stations are also conceivable, such as a cleaning station for the collecting container.

In another embodiment, it is provided that the bottle cleaning machine comprises detection equipment and a robotic arm, as well as a control unit according to one of the above embodiments and that the robotic arm is configured to transfer defective bottles to the container. manifold. An operator of the bottle cleaning machine or in general of a packaging processing machine comprising this bottle cleaning machine, can thus be completely exempt from the work that is linked to the discarding of defective or fallen bottles, as well as the emptying of the container. collector, so labor costs can be reduced while increasing the reliability of discarding and subsequent processing of defective or dropped bottles.

Furthermore, it may be provided that the collecting container(s) are arranged on rails connecting at least the bottle cleaning machine and the emptying station along a closed path such that the collecting container can return from the bottle cleaning machine. bottles passing through the emptying station to the bottle cleaning machine, the lanes forming a tight curve. This embodiment can be combined with all embodiments that refer to the collecting container and is not exclusively linked to the autonomous movement of the collecting container. In principle, with this embodiment a safe and therefore reliable movement of the collecting container can be carried out, either by an operator or autonomously, which increases the reliability of emptying the collecting container.

Detailed description

Figure 1 schematically shows a top view of a bottle cleaning machine 100 according to one embodiment. The bottle cleaning machine 100 typically comprises a cleaning area 101, not shown in detail here, in which bottles are cleaned for recycling or further use. In principle, within this area the bottles can be transported in any way, although they are generally transported in an orderly manner, so that selective cleaning is possible, also of the interior area of the bottles.

In front of the cleaning zone, an inlet zone is arranged, which is essentially formed by a transport device 111 and through which bottles can be fed into the cleaning zone 101. In the inlet zone, the bottles are transported in a flow disordered mass in a vertical position with the help of transport equipment. Upon delivery to the cleaning zone, separation and subsequent delivery may take place, for example, to special accommodations within the cleaning zone, although this is not the object of the present invention.

According to the invention, it is provided that in the entry area, in which the bottles are usually only transported at a reduced speed, a detection device 121 is arranged that can detect the bottles. According to the invention, this detection equipment is configured to detect whether the bottles have been dropped and/or are defective. For this purpose, the detection equipment is arranged above the transport level of the bottles, so that the detection equipment can detect the bottles from above. Since the detection device is configured as a camera, the optics are oriented in the direction of the transport device, so that the bottles transported in the transport device can be detected. For this purpose, the detection device 121 can be mounted on a support 120, which runs for example in the form of a bridge above the transport device, in particular the entrance area 110.

To ensure that all bottles can be detected in the transport equipment and in the entry area 110, it can also be provided that, depending on the size of the field of view that can be achieved with the detection equipment 121, several detection equipment are arranged. detection (represented schematically by the detection equipment 122), so that the total field of view forms at least a transverse strip with respect to the direction of transport (represented in this case by the fall) of the bottles in the entry area that goes through the transport equipment. This strip is preferably completely continuous and includes, where appropriate, a superposition of some visual fields of the detection equipment, to at least not leave blind spots.

Furthermore, a robotic arm 140 is provided, which has a gripping element with which it can remove defective and/or fallen bottles from the transport equipment 111 (in particular in the case of defective bottles, such as bottles with broken glass) or It can move the bottles to a new position, in particular, it can straighten fallen bottles again.

For this purpose, it is provided that a control unit 190 is connected both to the detection device 121 (and possibly to the other detection devices) and also to the robotic arm 140 in such a way that an exchange of data can take place. . The control unit can be configured, for example, as a computer and can be connected via corresponding data lines, such as cables or also via wireless communication means to the robotic arm and the detection device or devices, so that through this connection it can preferably a bidirectional data transfer is carried out.

Based on the bottles detected by the detection equipment(s) (in particular dropped bottles or defective bottles), the control unit can control the robotic arm 140 to remove the defective bottles from the transport equipment and straighten the bottles again. falls.

To increase its freedom of movement, the robotic arm 140 can advantageously be arranged on a support 143, which in turn is advantageously mobile along a rail 144 transverse with respect to the direction of transport of the bottles defined by the equipment. transport 111, so that the robotic arm 140 can preferably reach at least in a transverse strip with respect to the transport direction all the bottles in the transport equipment or in the entry area. Taking into account that the bottles usually move at a relatively low speed (up to a few centimeters per second) in the entry area, this strip may have a width parallel to the direction of transport of 15 cm, preferably 30 cm, particularly preferably 50 cm, so that the freedom of movement of the robotic arm is large enough to be able to straighten or remove also several defective or fallen bottles that are located at the same time in this strip.

The procedure for removing a defective bottle, in particular a broken one, is shown in Figures 2a to 2c.

In a first phase of Figure 2a, the detection equipment 121 detects a defective bottle 131 that is located in the entrance area 110. This bottle can be, for example, an at least partially broken bottle. In order for the detection device and/or the control unit (see Figure 1) to distinguish between a defective bottle and an intact bottle, it may be provided that a memory is assigned to the detection device or the control unit, in which that images or at least reference data related to undamaged bottles are deposited. By using image recognition programs, a defective bottle can be detected by comparison with the characteristics of an intact bottle. To support this, it can be provided that at least a part of the entrance area 110 in the field of view of the detection equipment 121 is configured transparently and, in this case, on the side of the entrance area 110 opposite to the detection equipment. detection 121, lighting equipment may be arranged that illuminates the bottles in the entry area 110 "from below". Thanks to this, the detection quality of the detection equipment can be improved.

In case no defective bottle is detected, the control unit will not control the robotic arm and the bottles will be fed to the bottle cleaning machine for cleaning there.

In the event that the detection equipment 120 detects the defective bottle 131, the step of Figure 2b follows. In this step, the robotic arm 140 is controlled to grasp the defective bottle with its gripping element 145 and remove it from the entry area 110 according to the direction of the arrow shown, at least in a direction perpendicular to the transport plane of the bottle. The bottles. To do this, the robotic arm can be configured with a gripping element 145, for example in the form of forceps. These grippers can wrap a defective bottle, and at least a part of the area of the gripping element that comes into contact with the surface of the bottle can advantageously be provided with a coating whose coefficient of friction with respect to the material of the bottle, for example glass or PET, is elevated, so that the bottle is prevented from slipping after having been grasped by the gripping element, without the need for considerable forces to act on the bottle. In particular, materials whose coefficient of static friction is ph“ 1, such as 0.9 or 0.95, especially preferably greater than 1, are preferably used.

Then, as shown in Figure 2c, the robotic arm 140 can dispose of the defective bottle 131 in a collection container 270 provided for this purpose. This collecting container is preferably located in an area that is located within the area of action of the robotic arm. Particularly preferred are embodiments in which the collecting container is arranged at least on one side of the rail described in Figure 1, so that after the removal of a defective bottle from the transport equipment, the robot moves along it. along the rail to one end of the rail and delivers the bottle there to the collecting container 270. To reduce the amplitude of the movement necessary for this, corresponding collecting containers can also be provided at the two ends of the rail.

In addition to the possibility of removing defective bottles from the transport equipment, according to the invention it is provided that fallen bottles can be straightened. This process is explained in Figures 3a - 3c.

In Figure 3a, the detection equipment 121 first detects a fallen bottle 131 in the entry area 110. The procedure can be analogous in this sense to that described in Figure 2a. In particular, a dropped bottle can be detected by comparison with features or images of non-dropped bottles stored in a memory.

After the dropped bottle has been detected, the robotic arm 140 is now controlled analogously to Figure 2b. However, in this case the robotic arm is not controlled so that it completely removes the bottle 131 from the entry area 110 by grasping it with the gripping element. In this embodiment, the robotic arm lifts the fallen bottle 131 and places it back correctly by means of an appropriate rotation of the robotic arm and, if applicable, the gripping element, so that it can be inserted back into the vertical position in the mass flow of bottles. Particularly preferred in this case is an embodiment in which the robotic arm lifts the initially dropped bottle to a height h greater than the length l of the bottles 130 in the transport plane. Once the bottle has been raised to this height, the robotic arm can rotate the bottle appropriately, without any possible contact with bottles in the entry area 110, which could otherwise cause the fall of more bottles. This post-lift turn is indicated by arrows 290.

Finally, in Figure 3c, the robotic arm lowers the bottle 131 again, thus placed in a vertical position, so that it is introduced into the mass flow of the containers. In this regard, the relative movement of the other bottles can be taken into account and the bottle 131 that is to be reintroduced is not simply lowered perpendicularly with respect to the transport plane, but this movement can be assumed at the same time a movement corresponding to the movement of the bottles in the transport equipment, so that collisions with other bottles are avoided. A corresponding movement during lifting of the bottle from the transport equipment can also be superimposed.

Furthermore, it may be provided that the bottle placed in a vertical position is not placed in the same position as that in which it was lifted to straighten it. This may be necessary, in particular, when bottles are transported with such a high dynamic pressure in the entry zone that the gap created by the lifting of the dropped bottle is closed by other advancing bottles. In such a case, the upright bottle 131 can also be replaced elsewhere in the entry area.

For this purpose, it can also be advantageously provided that an area separated by a delimitation is provided in the entry area, in which each bottle is placed in a vertical position and from which it is fed to the cleaning area 101 of the bottle cleaning machine. bottles. For this purpose, for example, a slide can be provided, positioned above the conveyor belt in Figure 1, which extends, for example, on the right or left edge of the entrance area shown in Figure 1 and which deflects the actual mass flow of the containers, so that, seen in the direction of transport of the containers, behind the slide there is an area free of bottles. The robotic arm can then introduce the bottles into this area, in a manner analogous to the procedure described in Figure 2c, moving, for example, along the rail 144 and placing a fallen, previously picked up bottle there in a vertical position.

Figure 4 shows another embodiment of the invention, in which a bottle cleaning machine 400 with an inlet area 410 in which bottles are transported in a mass flow is assigned a collecting container 420, to which they can be transported by for example defective bottles or other waste, such as straws or similar. According to the invention, it is provided that a filling level sensor is assigned to this collecting container or that it comprises such a sensor. This filling level sensor can be configured as an optical sensor or similar. However, an embodiment such as a scale is particularly preferred, in particular a weighing cell, which continuously controls, for example electronically, the weight of the material transported to the collecting container. Furthermore, it is provided that the collecting container (or a control unit integrated therein) can emit a signal indicating this filling level when a predefined filling level, for example 70%, 80% or 90%, is reached.

For this purpose, a signal output device 422 can be arranged in the collecting container or at another point of the bottle cleaning machine. This signal output equipment can emit a signal perceptible to a person and/or generate a signal indicating the fill level, which can be transmitted to one or more packaging processing machines or other components of the facility. In this sense, this signal can be optical, acoustic or electronic or several signals can also be emitted, each of them being optical, electronic or acoustic. Optical or acoustic signals can be emitted, for example, with the help of signal output equipment 422 in the form of a loudspeaker or a lamp. An electronic signal can be realized, for example, with the help of suitable data transmission equipment, such as a data cable or wireless transmission equipment (e.g. BlueTooth), and can be transmitted to other components, in particular to other machines. .

Particularly preferred are embodiments of the collecting container 420 in the form of a self-contained self-propelled unit. For this purpose, the collecting container may comprise a control unit or be connected to a control unit (for example the control unit of the bottle cleaning machine). In one embodiment, the movement of the collecting container can subsequently be controlled based on a signal emitted by the fill level sensor.

Figure 5 shows a possible embodiment of this embodiment. In this embodiment, several collecting containers 420 and 560 are optionally provided, which can move autonomously and independently of each other. An embodiment of the movement of the collecting containers along a rail 570 in the form of a closed curve is shown.

First, a collecting container 420 is arranged in a position 561 in which material can be transported to the collecting container. In this regard they may be, for example, defective bottles removed by an operator from the inlet area of the bottle cleaning machine 400 or other materials such as straws. Upon reaching a predetermined fill level, which is detected by the fill level sensor (e.g. 70%, 80% or 90%), the control unit can move the collecting container autonomously, i.e. without interaction with the operator, along the exemplary rail 570 to another position 562, in which the collecting container can transfer its contents to an emptying station 550. Preferably, this can also be done completely automatically or autonomous by means of a tilting equipment that can tilt at least the area of the collecting container in which the introduced material is located in the direction of the emptying station. The collecting container can then continue to be transported along the rail 570. Although it can easily be moved directly to the bottle cleaning machine 400, it can also be provided that it first passes through one or more additional stations. The collection container can, for example, be moved to a position in which a new film or a new plastic bag or the like is placed in the collection container to receive material by means of a cleaning station. The cleaning station can also clean the space in the collection container into which the material is introduced, to prevent an accumulation of dirt.

Furthermore, an optional additional collecting container 560 is shown in FIG. 5. This can be moved, for example, to position 561, to receive material from the bottle cleaning machine when the collecting container 420 itself has already reached a predetermined filling level and has been moved out of position 561. In this sense, the Collecting containers 420 and 560 can work alternately, so that at any time during operation of the bottle cleaning machine a collecting container is positioned at position 561 and can receive material.

The embodiment of Figures 4 and 5 is particularly advantageous in combination with the embodiments according to Figures 1 to 3. The collecting container of Figure 4 or the collecting container of Figure 5 can be used particularly preferably in combination with the embodiment of Figures 2a to 2c and act in this case as the collection container 270 already described. Thus, both the discarding of defective bottles from the input area 110 of the bottle cleaning machine and the subsequent evacuation of the bottles or other materials removed in this way can be carried out fully automatically, which makes the work considerably simplified. operator.

The embodiment described in Figure 5 refers to a rail 570. This rail can be realized as a physical rail and can form a linear drive, for example in combination with the collection containers 420 and 560, or the individual collection containers can be moved along the rail using suitable drive equipment, preferably electric motors. Alternatively, however, a more flexible movement of the collecting containers can also be achieved by means of optical guidance systems or by completely autonomous driving systems, which in principle allow the collecting containers to move in any desired way through an industrial warehouse in which The bottle cleaning machine is assembled. Thus, the collecting containers can not only be used with the bottle cleaning machine, but also additionally collect material in other machines and then feed it all together to the emptying station. In such a case it can be provided that, for example, the equipment that collects material not only from the bottle cleaning machine (see the robotic arm according to Figures 1 to 3), but also from other machines, such as recycling facilities or installations preform manufacturing or labeling machines, have an exchange of data with the collecting containers in such a way that these equipment can contact the collecting container(s), moving the collecting container(s) as needed to a corresponding machine.

In the previous explanations, it has always been assumed that the robotic arm is in principle capable of removing from the entry area 110 all the "defective" bottles detected (broken glass or also fallen bottles). However, the performance of the robotic arm (number of bottles processed per unit of time) is limited.

If a detection device 121 now detects a large number of defective bottles in a part of the inlet area 110, for example more than 10 broken bottles at the same time, this may indicate that in this case there is a problem upstream of the entry zone 110, which can no longer be resolved by the robotic arm due to its limited performance. Such a problem may lie, for example, in the loading of a group of destroyed bottles (also pallets of broken glass) or in a malfunction of an unpacker upstream of the transport equipment 111.

Regardless of the reason for the increase in the number of defective bottles, it may be provided that the control unit 190 stops the transport of the bottles to the cleaning machine, for example, by stopping the transport of other bottles by the transport equipment. This procedure can be activated, for example, if all or at least one of the provided detection equipment detects simultaneously or in a short time interval (e.g. 20 s, 30 s or 1 min.) a number of defective bottles (in this case case in particular bottles with broken glass) that exceeds the maximum number of bottles that can be processed by the robotic arm in this time interval or exceeds a previously determined limit value (for example, more than 5, 10 or 15 bottles per minute ).

Additionally, a warning signal activated by control of an acoustic (speaker) or optical (alarm light) unit can be issued by the control unit, which can indicate a problem to an operator and request further action. After transport of the bottles has stopped, the operator can for example manually remove the defective bottles from the inlet area and resolve the breakdown (for example, in the unpacker upstream of the transport equipment 111) before returning to continue operation.
