Definitions

  • the invention relates to a bottle washing machine according to the preamble of claim 1.
  • Generic bottle washing machines work with an endlessly rotating transport element, which consists of e.g. two parallel, synchronously driven chains. In between, elongated receptacles are arranged transversely to the direction of transport and fastened with their ends in opposite areas of the chains. The receptacles each contain a series of cells which individually and stationary hold the bottles with respect to the receptacle, see for example US-A-2 268 900.
  • the bottles are guided in the receptacles by the transport element through the bottle washing machine, whereby they are subjected to different processes required for effective cleaning.
  • One of these processes is that the bottles are passed overhead over spray nozzles arranged in rows.
  • the spray nozzles are each assigned to an opening of one of the bottles that are passed and direct a jet of liquid into the interior thereof.
  • the spray nozzles are in rows Aligned parallel to the receptacles, the number of nozzles per row corresponds to that of the bottle cell per receptacle.
  • Several such rows of nozzles are arranged one behind the other in the direction of transport. They form a so-called spray device.
  • the bottle washing machines described are designed for the cleaning of reusable glass bottles. In recent times, however, it has become increasingly common to also use plastic bottles in the reusable system. These bottles, which are usually made of polyethylene terephthalate (PET), are much lighter than glass bottles. As a special feature, they have a neck collar.
  • PET polyethylene terephthalate
  • the object of the invention is therefore to provide a bottle washing machine which is adapted to the special properties of reusable plastic bottles and enables effective cleaning of these bottles.
  • the receptacles for the bottles to be cleaned no longer have individual bottle cells. Rather, they consist of two parallel, spaced-apart guide rails, which support the plastic bottles so that they can slide on their neck collars.
  • the guide rails can be simple rods. In the present case in particular, where the bottles are to be guided overhead, such guide rails are preferred which engage around the neck collar from above and below.
  • Such bottle receptacles formed from guide rails can be arranged in a conventional manner between the two chains of a transport element. Due to the lower weights to be transported, it is also possible, however, to design the transport element in a single-stranded manner and to fasten the guide rails so that it projects laterally.
  • the pairs of guide rails offer a number of advantages. Firstly, they are cheaper, and they also have a significantly lower weight and volume, which e.g. plays an important role in the question of the carry-over of heat from heated cleaning baths and the carry-over of lye. They can still be used without retrofitting for different numbers of bottles or different bottle types as long as they have a neck collar.
  • the plastic bottles are inserted one after the other at one end of the guide rails and pushed from there towards the other end of the guide rails.
  • the bottles hang side by side, possibly additionally supported by guidelines in the bottle washing machine.
  • the guide rails can accommodate different numbers of bottles, the openings of which are located at different points of the receptacle, depending on the diameter of the bottle type used.
  • a conventional spraying device would no longer be able to hit the bottle mouths with its nozzles.
  • the invention therefore provides that the spraying device can be adapted to different bottle distances.
  • a plurality of spraying devices with different side distances between the nozzles can be provided, which can be switched on as required, or a spraying device with adjusting elements is provided which allow a change in the side distances between the nozzles.
  • the bottle washing machine according to the invention can thus be easily changed, for example, from cleaning many smaller bottles per receptacle to cleaning fewer larger bottles per receptacle. In such a case, the distances between the bottle openings in the receptacle would be greater.
  • the spraying device could be easily adjusted by correspondingly increasing the lateral spacing of the nozzles using the adjustment elements. Because of the smaller number of bottles to be cleaned in the case described, a number of nozzles in each row would also be superfluous. These nozzles could be switched off.
  • the term “row” always designates an arrangement of spray nozzles transverse to the direction of movement of the transport element.
  • an advantageous embodiment of the invention provides, according to claim 2, that the bottle washing machine according to the invention has a spraying device which, like in conventional bottle washing machines, has a plurality of parallel rows of spray nozzles. In this way, a better cleaning effect can be achieved.
  • each of the rows contains an identical number of nozzles in a matching arrangement.
  • the nozzles which have the same arrangement in the individual rows, are fastened on a common adjustment beam.
  • This adjustment bar can e.g. be a feed pipe that simultaneously supplies the nozzles arranged thereon or therein with cleaning liquid.
  • a further advantageous embodiment of the invention relates to claim 5.
  • guide elements are provided which align the bottles with their openings to the respectively assigned nozzle of a row or the nozzles accommodated in an adjusting bar of several rows.
  • the guide elements extend either above or below the receptacles parallel to the movement paths of the bottles in the transport direction.
  • a guide element can be formed, for example, from two lateral guide walls that expand in a funnel shape at their inlet end. It is understood that the position of the individual guide elements must be changeable in accordance with the nozzles to which the guide elements are aligned. On the one hand, this can be done by means of separate actuators which move in accordance with the actuators of the nozzles to let.
  • the guide elements can also be arranged directly on the actuators for the nozzles.
  • the foregoing relates to the case where a bottle washing machine is provided with a spraying device which is adapted from time to time to the type of bottle to be cleaned. But there is also the possibility that in a bottle washing machine for a longer period of time, e.g. only two different bottle types are to be cleaned. In this case, it is also conceivable to use a washing machine with e.g. to provide two spray devices connected in series, the nozzles of which are each set to one of the two bottle types. To switch from one type of bottle to the other, it is then sufficient to switch from one spraying device to the other.
  • Such actuators can be designed with individual drives for each longitudinal row of nozzles and, if appropriate, of guide devices and can be set, for example, by a computer as required.
  • mechanical proportional drives are advantageously provided, which ensure a laterally adjustable equidistant side distance.
  • a scissor grid construction very easily fulfills the function of equidistant side adjustment.
  • Such a parallelogram lever construction has the advantage over the scissor lattice construction, among other things, that it requires considerably fewer joints.
  • FIG. 1 shows a single-stranded chain-shaped transport element 10, on the links 11 of which a pair of guide rails 12a, 12b is arranged.
  • Bottles 13 with their neck collars 113 are inserted overhead into the guide rail pairs 12a, 12b serving as bottle receptacles 12.
  • the bottle openings 213 are therefore on the side facing away from the viewer.
  • the transport element 10 leads the receptacles 12 in the direction of the arrow T to a spray device 14.
  • the spraying device 14 contains a plurality of rows 15a-c of nozzles 16 which are aligned parallel to the guide rails 12a, 12b.
  • the nozzles 16, which correspond in terms of their orientation and arrangement in the individual rows 15a-c, are each arranged on common adjustment bars 17.
  • the Adjustment bars 17 in turn sit on a scissor-type actuator 18 which allows the adjustment bars 17 to be moved apart or together in the direction of the arrows S, the adjustment bars 17 being connected to the actuator 18 at the joints 18 ′ denoted by a small circle
  • Guide elements 19 are fastened to the adjusting bar 17, which in the case shown come into engagement with the neck of the bottles 13 pointing into the plane of the drawing and are intended to align the openings 213 with the nozzles 16 arranged on the adjusting bar 17.
  • the guide elements 19 each consist of two interconnected guide rails 19a, 19b, which have an inlet funnel at the inlet end 20.
  • the guide elements 19 do not necessarily have to be arranged on the adjusting bar 17 or the actuator 18.
  • guide elements 19 which should guide the bottles 13 in the area of the bottle body pointing towards the viewer, it is also possible to provide a separate actuator which changes the lateral spacing of the guide elements from one another in accordance with the actuator for the nozzles.
  • the guide elements 19 can adjust themselves to a certain lateral distance as a function of the position of the bottles 13 brought in and, in turn, align the nozzles 16 which may be associated therewith.
  • an alignment of the nozzles 16 would be determined by the arrangement of the bottles 13 in the bottle holder 12.
  • Such a construction is advantageous if the bottles 13 are received in the bottle holder 12 without play. In such a case, the bottles 13 are not placed on the nozzles 16, but the nozzles 16 are aligned according to the bottles 13.
  • the other case relates to the constellation that the bottles 13 still have a certain displacement within the bottle receptacle 12.
  • the distance between the nozzles 16 can be adjusted in advance and the bottles 12 can then be aligned in accordance with the guide elements 19 coordinated with the nozzles 16.
  • the last case is shown in the figure. It can be seen that the bottles 13 are arranged more or less arbitrarily in the bottle receptacle 12 in the lower region of the figure. In the further course of the transport, they then come into engagement with the funnel-shaped openings 20 of the guide elements 19 and are aligned in accordance with the nozzles 16 or the adjusting bars 17.
  • the nozzles individually or the adjusting bars 17 individually, that is to say not with the scissor-type grille 18 shown.
  • the individual drives can e.g. can be called up with a preselected program depending on the bottle type. It is e.g. it is also possible to quickly switch over to receptacles 12, which are loaded differently with bottles, by scanning the respective bottle arrangement in the receptacles and adjusting the nozzle spacing accordingly.
  • the setting is much easier. Only one side boundary 18a of the scissor lattice is to be held and the other 18b to be adjusted with a suitable drive, not shown.
  • the receptacles 12 are held on one side only on a single-stranded transport element 10, which is particularly suitable for plastic bottles is.
  • the receptacles 12 can also be held with their two ends in a conventional two-strand transport element.
  • the nozzles 16 are shown as simple, vertically upwardly spraying nozzles. These nozzles can be designed to rotate in a conventional design, specifically rotating around axes arranged parallel to the receptacles 12, the nozzles being driven in rotation synchronously with the speed of movement of the transport element 10. It is thereby achieved that the nozzle jets follow the bottle openings 213 which are passed over a part of the way.
  • the nozzles 16 With variable lateral spacing, it can be advantageous to derive the drive of the nozzles individually from the past movement of the receptacles 12, for example by means of star wheels which engage the rods 12a, 12b of the receptacles 12.
  • the nozzles are laterally displaceable on drive axles which are arranged parallel to the receptacles 12 and which at their end lying in the region of the transport element 10 are in synchronous engagement with the latter, for example via chain wheels.
  • a scissor-type actuator 18 is provided for equidistant side adjustment of the adjustment bars 17 carrying the nozzles 16.
  • This construction is technically relatively simple, but also has disadvantages, for example due to the large number of joints required. In the embodiment shown, 20 joints are required.
  • the supply of the flushing liquid to the nozzles 16 is particularly problematic here. If an attempt were made to supply the liquid to the adjusting bars 17 from the side via the scissor bars, a large number of rotatable pipe joints which would be well sealed would be required.
  • Figure 2 shows a variant of the actuator, which has several advantages over the embodiment shown in Figure 1.
  • adjustment bars 17 with nozzles 16 are arranged in a spray device in exactly the same way as shown in FIG. 1.
  • bottles and their transport devices are not shown. These can be designed in exactly the same way as in FIG. 1.
  • the adjustment bars 17, which are designated 17.1, 17.2 and 17.3 for further distinction, are provided on an actuating drive 28 which essentially consists of two longitudinal levers 29, 30 and three transverse levers 31.1, 31.2 and 31.3.
  • Each of the transverse levers is supported at its ends with a joint on both longitudinal levers 29, 30.
  • the longitudinal lever 29 is supported at one end with a joint 34 at a fixed point.
  • the longitudinal lever 30 is mounted at its corresponding end with a pipe coupling 35 on a supply pipe 37 fastened to a fixed point 36.
  • the adjustment bars 17.1, 17.2 and 17.3 are designed as liquid supply pipes for the nozzles 16.
  • the part of the cross lever 31.1, 31.2 and 31.3 on the right is also designed as a feed tube, while the part of the cross lever on the left as shown in FIG. 2 can be designed as a simple rod.
  • the longitudinal lever 30 is also designed as a feed pipe.
  • Flushing liquid for the nozzles is supplied via the fixed feed pipe 37, passes through the pipe coupling 35 into the longitudinal lever 30 and out of this via the pipe couplings 33 into the parts of the pipe Cross lever 31.1, 31.2, 31.4, from which it is fed to the adjusting beams 17.1, 17.2, 17.3 and is fed from these to the nozzles 16.
  • the nozzles 16 are supplied with liquid via a total of only 4 required rotatable pipe couplings. Flexible hose lines are not required.
  • the actuator 28 of FIG. 2 allows exactly the same equidistant lateral adjustment of the adjustment bars 17.1, 17.2, 17.3 as the scissor-type actuator 18 according to FIG. 1 does.
  • the joints 32 and 34 on the longitudinal lever 29 are arranged equidistantly, as are the pipe couplings 33 and 35 on the longitudinal lever 30.
  • the adjustment bars 17 become parallel to the position shown in broken lines postponed. Their side spacing changes, but they remain equidistant.
