Description
- The present invention relates to an apparatus for processing and filling containers for liquids. In particular, the present invention relates to the field of apparatuses for filling beverage kegs.
- The processing of kegs can comprise for example the handling of the kegs in order to perform operations for washing them.
- The present invention relates to the field of apparatuses adapted to perform the positioning of kegs, typically suitable for containing liquid products, such as for example beverages, on a processing station. Once they have been positioned on the processing station, the kegs can be washed or filled with any product, depending on the situation, and are subsequently unloaded from the processing station and sent to the subsequent processing step.
- As is known, in the field of apparatuses for processing and particularly filling kegs for beverages in general, rotary transfer machines are usually used on which the keg to be processed is loaded automatically or manually and is then transferred in succession to the various processing stations.
- This known type of solution entails the provision of very complicated, bulky and inflexible machines, with a fixed processing cycle which depends on the angular rotation rate of the machine and cannot be modified even in the presence of containers of a different format.
- Another disadvantage of a rotary apparatus is that it is not possible to replace from the processing cycle a keg which is defective or which, for any reason, has to be excluded from the processing; this operation is instead possible on the innovative machine.
- In order to eliminate or reduce the drawbacks noted above which affect known types of apparatuses, and mainly in order to optimize the keg processing cycle, Applicant has devised a machine for filling kegs of the linear and non-rotary type, which is disclosed in patent no.
W003014003 - This type of processing apparatus comprises a keg feeding conveyor, which can be constituted by a linear element such as a substantially straight conveyor belt, a plurality of units for processing the individual kegs arranged in mutual alignment, and a keg unloading conveyor, which is laterally adjacent to the keg processing line on the opposite side with respect to the side of the feeding conveyor. The apparatus thus configured is further characterized in that it comprises a grip clamp, which is designed to handle the kegs. Such grip clamp is capable of gripping the keg during handling and of arranging it on the machine in the correct position for filling. Once the keg has been filled, the grip clamp positions a new keg to be filled in the processing station and at the same time, by means of push rods with which said clamp is provided, an already-filled keg is pushed away from the processing station toward the output conveyor.
- This type of machine has allowed to arrange a plurality of processing units in a line and allows to perform the processing and filling of the individual kegs independently, so as to be able to reject rapidly any defective kegs. Moreover, the provision of an apparatus of this type has allowed to simplify considerably the mechanical systems of the entire machine with respect to machines commonly used in the background art.
- The aim of the present invention is to provide an apparatus for processing and filling kegs, typically kegs for beverages in general, which allows to improve further the steps for handling and transferring the kegs, so as to make the entire processing method more efficient, thus improving the productivity of the apparatus.
- Within this aim, an object of the present invention is to provide an apparatus for processing and filling kegs which has an extremely simple structure and is therefore cheaper as regards its manufacture and as regards its maintenance.
- Another object of the present invention is to provide an apparatus for processing and filling kegs which is extremely reliable thanks to the highly simplified mechanical systems and is subjected to less stress for an equal production rate with respect to conventional machines.
- Another object of the present invention is to provide an apparatus which solves or reduces the drawbacks which affect currently known machines of the background art. In particular, with respect to rotary-type machines, the apparatus according to the present invention allows to act very easily in order to vary the times of the keg processing cycles, also differentiating them among the various processing stations (times which are "inherently" fixed for rotary machines and therefore cause the high number of kegs rejected by these machines).
- Moreover, the apparatus according to the present invention allows the distribution of fluids to the heads to occur by means of simple static ducts, which are practically immune to breakages, differently from the extremely complicated, expensive and fragile rotary distribution unit of rotary machines.
- This aim and these and other objects, which will become better apparent hereinafter, are achieved by an apparatus for processing and filling kegs, particularly suitable for containing liquids such as beverages and the like, of the type which comprises a processing station of the linear type, in which said kegs are mutually aligned, characterized in that it comprises a loading conveyor, which is arranged laterally to said processing station, and an unloading conveyor, which is also arranged laterally to said processing station and on the opposite side with respect to said loading conveyor, and in that it furthermore comprises a handling unit which is adapted to move said kegs from and toward said processing station.
- The processing station can perform operations such as keg filling, washing or any operation of another kind.
- Further characteristics and advantages of the present invention will become better apparent from the following detailed description, given by way of non-limiting example and illustrated in the accompanying figures, wherein:
- Figure 1 is a schematic plan view of the apparatus according to the present invention in a first embodiment and in a step in which all the kegs are arranged on the processing station;

- Figure 7 is a view of a step which follows the step of Figure 6 and in which a keg which has ended the processing cycle is unloaded from the processing station while the new keg is arranged in its place;
- Figure 8 is a view of a step which follows the step of Figure 7 and in which the new keg is in its final position on the processing station and the handling unit is moved away from the processing station and arranged at the loading conveyor while a new keg is already on the loading conveyor;
- Figure 9 is a view of a detail of the handling unit according to the first embodiment of the apparatus according to the present invention;
- Figure 10 is a view of a detail of the handling unit provided with a paddle according to a second embodiment of the apparatus according to the present invention.
- With reference to the cited figures, the apparatus for processing and filling kegs for beverages according to the present invention, generally designated by the
reference numeral 1, comprises aconveyor 2 for feeding or loading thekegs 8a in input, which can be of any type. Advantageously, saidloading conveyor 2 can be constituted by a conveyor belt or by a similar system. - The apparatus according to the present invention comprises a
processing station 3, on which thekegs 8b to be processed are positioned. The operations that the processing station can perform are several, from the filling to the washing of the kegs, and the type of process does not affect the structure of the apparatus according to what is described here. Once thekegs 8b have been positioned on the processing station, they can be for example filled with liquid substances, such as beverages, medicines, oils and the like, or with solid products, such as powders, pastes, amalgams and the like. - The
apparatus 1 according to the present invention further comprises anunloading conveyor 4. Advantageously, said unloadingconveyor 4 can be constituted by a conveyor belt or by a similar system. The unloadingconveyor 4 and theloading conveyor 2 are arranged on opposite sides of theprocessing station 3, which is substantially longitudinally elongated, so that it can accommodate the kegs being processed in an aligned condition. Accordingly, in the embodiments illustrated by way of example in the accompanying figures, theloading conveyor 2 and theunloading conveyor 4 also are substantially rectilinear and longitudinally elongated and can lie substantially parallel to said processing station. Of course, a non-rectilinear processing station flanked by loading and unloading conveyors which are also non-rectilinear is still within the scope of the inventive concept on which the present invention is based according to the content of the appended claims. - Again with reference to Figure 1, at the side of the apparatus where the
loading conveyor 2 is located, theapparatus 1 according to the present invention is provided with ahandling unit 5, which is capable of moving longitudinally along the loading conveyor, substantially parallel thereto and therefore along theprocessing station 3 parallel thereto, since the loading conveyor lies substantially parallel to theprocessing station 3, and transversely, i.e., at right angles to the longitudinal direction of the processing station, from theloading conveyor 2 toward theprocessing station 3, and vice versa, by means of an appropriate motor drive. The handling unit can therefore move both parallel and at right angles to the processing station. - In particular, the
handling unit 5 can be constituted by abody 7 and by an adequate handling system of a known type. In the embodiment illustrated by way of example in the accompanying drawings, the handling unit can be mounted on a framework which connects it to a double system of toothed belts, which allow said handling unit to move along the two mutually perpendicular directions. - The handling
unit 5 is conveniently shaped so that it can block the stroke of anincoming keg 8a which moves by being conveyed by theloading conveyor 2. At the same time, thehandling unit 5 must have a configuration adapted to release the keg that must be processed once said keg has been positioned on theprocessing station 3. - One possible configuration of the handling unit suitable to be mounted on the apparatus according to the present invention is shown in Figure 9. According to this specific configuration given by way of example, the
handling unit 5 is substantially L-shaped, with two mutually parallel axes, axis A and axis B. Considering the longitudinal extension of the apparatus, the handling unit according to this first embodiment may conveniently have the side perpendicular to the longitudinal direction of the processing station which determines axis A, and the side that is parallel to the longitudinal direction of the processing station which forms with said perpendicular side a connecting portion which forms a first supportingsurface 5a with a concavity which is adapted to rest against the side wall of a keg and to stop and retain the keg which is moving on theloading conveyor 2, keeping said keg rested against said first supportingsurface 5a. - Axis B is aligned with the transverse axis of the keg when said keg is in contact with the
surface 5a. Likewise, axis A must align itself with a transverse axis of the keg which must be unloaded from theprocessing station 3. Thehandling unit 5 is further provided with a second supportingsurface 5b, which is adapted to make contact with the side wall of a keg so that it can apply a thrust to said keg. Figure 9 illustrates two axes A and B which are substantially mutually parallel. - In an alternative embodiment of the
handling unit 5, such unit is provided with a movable arm orpaddle 10. In particular, thehandling unit 5 has, in this case also, a first supportingsurface 5a with a concavity which is suitable to rest against the side wall of the keg, but at the end of the handling unit that during operation is directed toward the processing station the handling unit comprises a movable arm orpaddle 10, which is mounted on anaxis 9 which allows the rotation of themovable arm 10. - The figures are all plan views, i.e., top views, of the apparatus according to the present invention. Likewise, Figure 10 also is a top view of the handling unit. Taking therefore the plane of Figure 10 as a horizontal plane, the
arm 10 can rotate about theaxis 9, tracing a circle centered on theaxis 9 and substantially at right angles to the horizontal plane. The rotation of thearm 10 allows to release the keg, which rests on theconcave surface 5a of the handling unit. Figure 10 indeed illustrates thearm 10 in the lowered configuration. - The
arm 10 can be provided advantageously with anelement 11 which constitute a second supporting surface which is shaped so as to be adapted to make contact with the lateral surface of a keg. - Operation of the apparatus for processing and filling kegs according to the present invention is now described.
- With reference to Figure 1, a first embodiment of the apparatus according to the present invention provides a
handling unit 5 of the type shown in Figure 9 and described above. - The
handling unit 5, which is capable of sliding along theloading conveyor 2, advances along said direction until it is arranged at akeg 8b, which lies on theprocessing station 3 and has ended the processing step, so that it must be unloaded from the processing station. - The movements of the
handling unit 5 in a longitudinal and transverse direction are obtained by means of mechanical systems of a known type. Movements in the longitudinal and transverse direction of thehandling unit 5 are achieved by means of known types of mechanical systems. In particular, the longitudinal movement of thehandling unit 5 can be provided by mounting said unit on a toothed belt provided with a motor. Likewise, the transverse movement can be provided by means of a similar system with a transverse belt. - In an alternative embodiment, the handling unit can be provided with a motor in the
body 7, which is adapted to move longitudinally said handling unit along a longitudinal rail. In another possible embodiment, the transverse movement can occur by virtue of a hydraulic piston which is arranged at thebody 7 of said handling unit. - Going back to the processing steps of the apparatus, when the
handling unit 5 has the axis A at the transverse axis of the keg to be unloaded, the numeric control system, of a known type, with which the machine is provided and which coordinates all the movements of the apparatus, stops thehandling unit 5. At this point thehandling unit 5 moves in a transverse direction and its second supportingsurface 5b, which lies at the axis A of Figure 9, makes contact with the lateral surface of the keg, pushing it out of theprocessing station 3 and moving said keg onto the unloadingconveyor 4. Thekeg 8c is then unloaded from the processing station and at the same time, as illustrated in Figure 2, anew keg 8a is placed on theloading conveyor 2. The control system adjusts, depending on the rate of motion of theloading conveyor 2 and of the position of thehandling unit 5, the moment when thenew keg 8a is placed on theloading conveyor 2. Once thekeg 8c has been unloaded (Figure 3) the handling unit performs an L-shaped movement, which returns it at theloading conveyor 2, so that it can affect the newincoming keg 8a by means of thesurface 5a. In this step, the handling unit has aligned the axis B with the transverse axis of thenew keg 8a and said axis B is conveniently centered by the control system at the exact position of theprocessing station 3 in which thenew keg 8a must be inserted, which coincides with the position that has just been cleared because thekeg 8c has been unloaded. - Once the axis B has been aligned with the destination position of the new keg on the processing station, the
handling unit 5 performs a new transverse movement (Figure 4) which allows to position the keg on said processing station. Thehandling unit 5 then retracts again, performing a new transverse translational motion and returning at the loading conveyor, and a new processing cycle can begin. - Figure 10 illustrates a second embodiment of the
handling unit 5. The apparatus according to the present invention provided with the handling unit according to the embodiment of Figure 10 provides a processing cycle which is characterized by loading and unloading steps, which differ, in some of their parts, from what has been described for the first embodiment. The steps of this processing cycle are described hereafter. - With reference to Figure 5, the
handling unit 5 is arranged at theloading conveyor 2 and anew keg 8a is placed on theloading conveyor 2. The control system arranges thehandling unit 5 at akeg 8b which is located on theprocessing station 3 and has ended processing and is therefore ready to be unloaded. The control system aligns the axis C of thehandling unit 5, illustrated in Figure 10, with the transverse axis of the keg to be unloaded. As shown in Figure 6, the handling unit accommodates thenew keg 8a before unloading thekeg 8b from the processing station, differently from what occurred with the handling unit according to the first embodiment described above. Again with reference to Figure 6, the handling unit moves transversely, pushing, by means of thearm 10 which is in the lowered position, thekeg 8b, unloading it from theprocessing station 3 and moving it onto the unloadingconveyor 4. In particular, the second supportingsurface 11 abuts against the lateral surface of the keg to be unloaded, allowing to push said keg toward the unloading conveyor. - As can be seen from Figure 7, when the
keg 8b has been pushed onto the unloading conveyor and at the same time thenew keg 8a is in the corresponding position on theprocessing station 3, thearm 10 is raised so that thehandling unit 5 can be retracted without the keg just positioned on the processing station being moved again by said handling unit. - Figure 8 shows that while the
handling unit 5 retracts, returning with a transverse movement at the loading conveyor, the control system has already placed anew keg 8a on said loading conveyor. Thearm 10 of the handling unit is then lowered again so that the handling unit is in the cycle start configuration and is ready to accommodate the new keg to be arranged on theprocessing station 3. At this point, a new operating cycle of the apparatus can begin. - As shown by the description of the steps of the operation of the apparatus, the two different embodiments of the
handling unit 5 allow a different optimization of the keg handling times. In particular, the handling unit provided with a movable arm allows to perform a single transverse movement of the handling unit to unload the already-processed keg and at the same time load the new keg to be processed. In comparison with the greater complexity of the handling unit and therefore of the control system which must also move the movable arm, the system thus structured allows to optimize the loading and unloading steps and to reduce the number of strokes of the handling unit. - The two illustrated embodiments for the apparatus considered here are within the scope of the same inventive concept on which the present invention is based. The optimization of the cycle for handling the kegs from and toward the processing station is in fact obtained by the apparatus as described in the appended claims.
- It has thus been shown that the present invention achieves the proposed aim and objects. In particular, an apparatus has been described which is capable of optimizing the steps for handling the kegs to be processed and/or filled, reducing the time required for loading and unloading the kegs from a linear processing station and at the same time simplifying considerably the apparatus with respect to what is currently available in the field from the background art.
- Of course, numerous modifications are evident and can be performed promptly by the person skilled in the art without thereby abandoning the scope of the protection of the present invention.
- Therefore, the scope of the protection of the claims must not be limited by the preferred embodiments or illustrations given in the description by way of example, but rather the claims must comprise all the characteristics of patentable novelty which can be deduced from the present invention, including all the characteristics that would be treated as equivalent by the person skilled in the art.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
