Description

The invention relates to a mobile device for rinsing drinking vessels, in particular glasses and mugs.

Dishwashers used in households are well known. However, these are not very suitable for mobile use and the rinsing process in particular is regularly of considerable duration. In that regard, these dishwashers are unsuitable, for example, for mobile use in marquees at folk festivals.

Often find instead so-called

Tunnel dishwashers use in which dishes to be cleaned run linearly through a washing line, as it were. Lengths of several meters are quite common, caused by successive stations such as pre-cleaning, main cleaning and drying. Due to this length, tunnel dishwashers of this type can usually only be transported in disassembled form, which means that assembly and disassembly take a considerable amount of time. Loading, for example, in a normal station wagon is only very rarely possible due to the overall length.

Hand washing devices are not a real alternative in the field of commercial glass washing. On the one hand, they require a paid dishwasher. In particular, however, DIN 10511 “Commercial glass washing with glass washing machines” cannot be fulfilled due to faulty washing technology. Basically, due to the regularly used brushing technique, there is a risk of cross-contamination and glass breakage as well as poor cleaning, e.g. if a glass is soiled by lipstick.

Against this background, the invention has set itself the task of providing an extremely compact yet powerful mobile device for rinsing drinking vessels, in particular for rinsing glasses and mugs, which can also be easily transported in a station wagon, for example, and which DIN 10511 is sufficient.

This technical problem is solved by a device according to claim 1.

The device according to the invention has a number of advantages. First of all, the device is extremely compact and requires only a small installation area. It can also be loaded in a car in a simple manner.

In the device according to the invention, the linear path is replaced by a circular movement, for example in a tunnel dishwasher, and a very short overall length is thereby achieved. For this purpose, the device has a vertical, central axis driven by a swivel drive. Height-adjustable gripping devices are provided that are radially evenly spaced in a common plane, connected to the axis and rotate with it. A controller coordinates the detection of the drinking vessels, the up and down movements of the gripping devices during a revolution at the individual stations and the delivery of the drinking vessels.

By lowering a gripping device at a first pick-up station, a drinking vessel is gripped by it. After gripping the drinking vessel, the gripping device is raised and, with or after the lifting, this drinking vessel is transferred to a subsequent station by rotating the axis and lowered there for treatment. With the lowering, a second gripping device following this first gripping device is also lowered and grips the next drinking vessel. This process is repeated several times and after a number of stations arranged in a ring have been passed through, the drinking vessel is set down at a last, a delivery station, by lowering the gripping device.

The device according to the invention thus allows a largely continuous flow and a gentle cleaning of drinking vessels, avoiding glass breakage.

It can be provided that each gripping device has a lifting drive. However, it is preferred that a lifting drive is provided for the vertical position of the central axis. All gripping devices are then raised or lowered simultaneously with the axle.

Against this background, it is expedient if the number of gripping devices corresponds to the number of stations. With each lowering of the gripping devices thus takes place Treatment of a drinking vessel at a station or receiving or dispensing one.

It has proven to be expedient if the gripping devices are arranged in a uniform division over the circumference, as are the individual stations. The same angles of rotation are then specified from station to station.

In a structural configuration it can then be provided that the gripping devices are arranged on a receiving star, an impeller or a simple plate.

The design of the gripping devices is largely subject to change. Vacuum cups are preferred. An alternative is fingers holding a drinking vessel pinched.

The design of the drives is also largely subject to change. Pneumatic and electric drives, possibly also mechanical ones, are considered in particular.

It has proven to be expedient if a lifting drive and/or a pivoting drive for the central axis and/or a vacuum pump for subjecting the vacuum suction cups to negative pressure is/are arranged above the gripping devices.

In addition, it can also be provided that a guide for the central axis is arranged above the gripping devices.

These measures offer the advantage that the space below the gripping devices for the arrangement of each stations and their design is largely subject to change.

The supply and/or removal of the drinking vessels can take place on slides and/or in magazines. An alternative is provided by pivoting, half-moon-like bases, each of which has a fixed guide with a stop arranged on it. A certain number of drinking vessels to be rinsed are placed on a first floor, usually by hand and outside the device. The number of drinking vessels preferably corresponds to the number of stations. With each pivoting of the gripping devices, the base pivots into the device until another glass hits the stop and can be gripped there by the subsequent gripping device.

The drinking vessels are then placed on a floor that can be swung in the opposite direction.

If there is sufficient space next to the individual stations, it can be provided in a further alternative that the supply and/or removal of the drinking vessels takes place on turntables, above each of which a fixed guide with a stop is arranged. Such a supply and removal of the drinking vessels has the advantage that continuous operation of the device is possible.

For the cleaning process of a drinking vessel, a second station is provided after the receiving station for pre-cleaning, a third station for main cleaning, in particular in an ultrasonic bath, and a fourth station for post-cleaning and/or drying before the drinking vessel is transported to the last the delivery station.

The ultrasonic bath offers the advantage of very good cleaning, even if it is soiled by lipstick, for example, but also with herpes, viruses such as corona viruses or the like.

Further stations are also possible, for example the device can be extended by a control stage in which a rinsed drinking vessel is checked for cleanliness and freedom from germs.

Ultimately, it is provided that the device has a housing with two openings for feeding in and dispensing the drinking vessels.

The device 1 has a round bottom plate 2 supported by continuous rods 3,4 cover plate 5. A housing connected to it is not shown in the drawing.

Between the bottom plate 2 and the top plate 5, two support plates 6.7 are arranged. In the exemplary embodiment of the device 1 , drinking vessels are cleaned at three stations above the lower support plate 7 . Two other stations are used to pick up the drinking vessels or to hand them over.

The supply of drinking vessels 8.9 is a horizontally rotating turntable 10 on which drinking vessels are placed by hand.

Above the turntable 10 is a double guide 11 fixed to the device via a rod 12 on the carrier plate 7 is supported. Through the guides 11 a stop 13 is formed for the parked drinking vessels. A drinking vessel held against this stop 13 is then gripped by a lowered gripping device 14, here in the form of a vacuum suction cup. After lifting the gripping device 14 into the in figure 1 In the position shown, the gripping device 14 is pivoted about a central, vertical axis toward a second station 15, which in the exemplary embodiment is formed by a pre-rinsing unit. Consequently, another drinking vessel can then be placed on the turntable 10, which enables the device 1 to be continuously loaded with drinking vessels.

A raised drinking vessel 8 is then lowered into the pre-rinse unit and previously cleaned. Sync with After this lowering, a gripping device following the gripping device 14 grips a drinking vessel, which can be obtained by pivoting the base 10 in the direction of the arrow, cf 6 , was spent in contact with the stop 13 of the guide 13.

After the pre-cleaning in the pre-rinsing unit of the station 15, a drinking vessel 8 is lifted again and pivoted to a third station 16, in which a main cleaning takes place, for example in an ultrasonic bath. After renewed lifting and swiveling and subsequent lowering, a subsequent cleaning and/or drying takes place in a fourth station 17 .

After the cleaning process has been completed, the drinking vessels are placed on another rotating turntable 18 which rotates in the opposite direction to the turntable 10 , with the result that drinking vessels are pivoted against the stop 19 of the guide 20 . 6 shows the two turntables 10,18 outside of the device 1, where the turntable 10 can be equipped with drinking vessels or the turntable 18 drinking vessels can be removed.

In order to get enough space for the turntable 10,18, individual stations can be elevated above the support plate 7.

Below the support plate 7, rotary drives 25,26 are provided for the turntables 10,18. Rinsing pumps 27, 28 for pre-rinsing and post-rinsing are also arranged there. This leaves the space between the support plates 7, 8 largely free for the design of the individual stations.

A contributing factor is that a lifting drive 30 is arranged above the support plate 6 for adjusting the height of the central axis. Immediately below the support plate 6 and thus above the gripping devices 14, a pivoting drive 31 is provided for pivoting the central axis.

The gripping devices 14 are connected to the central axis at a uniform radial distance in a common plane via a receiving star 32 . This means that the five gripping devices here are height-adjusted and pivoted synchronously.

In the exemplary embodiment, the number of stations corresponds to the number of gripping devices which are arranged over the circumference at a uniform pitch, in this case of 72°. A vacuum pump is also arranged on the carrier plate 6 in order to apply a negative pressure to the gripping devices 14 , which are designed here as vacuum suction cups. Guides 34,35 are also provided there for vertical guidance of the central axis.
