FIELD
BACKGROUND
[0002] Production of cans, such as beverage cans or food cans, typically involves a step wherein newly formed cans are passed through a can washer. In the can washer the cans are cleaned to remove contaminants, for example residue from earlier manufacturing steps, and additional surface treatments may be applied, for example in preparation of subsequent manufacturing steps.
[0003] For such purposes, the cans are exposed to a succession of spray curtains of wash liquid generated by sequentially placed nozzle arrays. Re-configurability of the spray curtains is highly desirable as the spray curtains are carefully arranged to optimise efficacy of the can washer dependent on the size and shape of the cans. Where production is changed to a different size or shape of cans, the spray curtains may need to be adapted for optimised operation.
[0004] Adapting the spray curtains, however, may be a cumbersome and time-consuming process due to the size and weight of the supply risers on which the nozzle arrays are carried in certain conventional can washers. In particular, access to the supply risers may be provided from one side of the can washer, while the supply risers are connected and secured on the other side of the can washer.
[0005] Therefore, it is now desired to provide a can washer as an alternative to previously available designs. The example embodiments have been provided with a view to addressing at least some of the difficulties that are encountered with current can washers whether those difficulties have been specifically mentioned above or will otherwise be appreciated from the discussion herein. DE507274C and EP1122338A2 describe examples of the related art.
SUMMARY
[0006] It is an object of the present invention to overcome at least one of the above or other disadvantages. According to the present invention there is provided an apparatus and method as set forth in the appended claims. It is an aim of the present invention to provide a can washer which is easily adaptable to cans of various sizes or shapes. It is a further aim to provide a can washer which may be convenient for maintenance and repair. It is yet another aim to provide a can washer which may generate improved spray curtains.
[0007] A can washer according to the present disclosure is easily adaptable to modify a spray curtain generated by the can washer. Suitably, a spray bar arranged to generate the spray curtain is easily replaceable as it is carried by a guide to improve insertion into and removal from the can washer.
[0008] The guide may be a support structure taking any suitable form. In some examples, the guide forms a sleeve which retains the spray inside. In other examples, the guide forms a number of support beams on which the spray bar is carried.
[0009] Conveniently, the guide extends towards an access side of the can washer from which the spray bar is inserted or removed. With the guide extending toward the access side, insertion or removal of the spray bar into the can washer may amount to insertion or removal of the spray bar into the guide. As the guide extends towards the access side to receive or release the spray bar closer to the access side, the guide may improve insertion and removal of the spray bar and, thus, improve adaptability of the generated spray curtain.
[0010] Accordingly, there is provided an exemplary embodiment of a can washer for treatment of cans.
[0011] The can washer comprises a conveyor belt arranged to transport cans through the can washer. The can washer comprises a housing of elongate shape wherein the conveyor is arranged centrally, operating along a longitudinal direction of the can washer. The can washer has a supply side and, located opposite thereto, an access side. In some examples, the can washer has a substantially cuboid shape having opposing elongate sides, where the supply and access side correspond to the elongate sides. A removable access panel is located on the access side for opening the housing.
[0012] The can washer comprises a supply manifold. In use, the supply manifold holds wash liquid from which a spray curtain is generated. Suitably, the supply manifold is provided on the supply side.
[0013] The can washer comprises a supply port. Suitably, the supply port is in flow communication with the supply manifold. Conveniently, the supply port is located on the supply side.
[0014] The can washer comprises a spray bar. Suitably, the spray bar is arranged to generate a spray curtain across a longitudinal direction of the can washer along which cans are transported. Conveniently, the spray bar comprises an inlet portion arranged for connection with the supply port.
[0015] The can washer comprises a guide. Suitably, the guide is arranged to receive and carry the spray bar upon insertion of the spray bar through the access side.
[0016] The guide extends from the supply side at least halfway towards the access side. Suitably, the guide has an elongate shape. In some examples, the guide extends 75% to the access side. In other examples, the guide extends 85% to the access side. In yet further examples, the guide extends substantially all the way to the access side.
[0017] In some examples, the guide is configured to receive the spray bar and guide the spray bar into connection with the supply port of the supply manifold.
[0018] The can washer may be convenient to access in order to, for example, perform maintenance or repair work. Suitably, in some examples there is provided a guide which is readily detachable from the can washer. Conveniently, with both the spray bar and the guide being removable, access to an interior of the can washer may be improved.
[0019] In some examples, the guide is removable from the can washer. Conveniently, any suitable fastening mechanism may be used to secure the guide inside the can washer.
[0020] In some examples, the guide is arranged to secure to the supply port. Conveniently, the guide has a docking end which is arranged to fit around the supply port. Suitably, the guide is configurable to secure the guide and the supply port relative to each other.
[0021] In some examples, the docking end of the guide and the supply port are configurable to couple using a bayonet fastening mechanism. Suitably, pins may be provided on the supply port and slots may be provided on the docking end. Conveniently, the pins are receivable by the slots and locatable in recesses of the slots in order to secure the guide to the supply port.
[0022] In some examples, the can washer comprises a support member for supporting the guide. The guide as well as the spray bar may have a substantial weight and, accordingly, the support member may reduce any strain exerted under a gravitational pull.
[0023] In some examples, the support member comprises a bracket which may be configured to retain the guide.
[0024] In some examples, the spray bar comprises a sleeve. The sleeve is arranged to receive and carry the spray bar. Suitably, the spray bar forms a passage into which the spray bar may be received.
[0027] In some examples, the spray bar is substantially cylindrical. Suitably, the spray bar defines a radial direction. Suitably, the spray bar defines a longitudinal direction. The radial direction and the longitudinal direction may be substantially orthogonal.
[0028] In some examples, the outlet is arranged to point into the radial direction of the spray bar.
[0029] In some examples, the spray nozzle, when fitted to the outlet, is arranged to spray into the radial direction.
[0030] In some examples, the spray bar comprises a plurality of outlets arranged in a row. Suitably, the slot is arranged to receive the plurality of outlets. In use, the plurality of rows sequentially fit into the slot as the spray bar is inserted into the guide.
[0032] Conveniently, the slot may ensure correct alignment of the spray curtain when the spray bar is inserted.
[0033] The can washer may be suitable for generating spray curtains which are improved over certain conventional can washers. According to arrangements found in the conventional can washers, a single spray bar would be arranged to generate a pair of spray curtains. Feeding wash liquid through a single spray bar into two spray curtains, however, may lead to a pressure differential across the spray bar. Accordingly, a pair of non-uniform spray curtains may be generated and, hence, efficacy may be adversely affected. Such an arrangement is nevertheless used in order to increase the number of spray curtains per unit length, because a compact spacing of the spray bars themselves is not possible. This is due to the size of clamping mechanisms conventionally used to secure each spray bar. In particular, use of over centre clamps may require relatively large spacing between individual spray bars. By contrast, carrying a spray bar inside a guide may enable a more compact spacing of adjacent spray bars because no large clamping mechanism is required. Accordingly, a spray bar may be arranged to generate a single spray curtain only.
[0034] The can washer is for treatment of cans. Suitably, the spray bar is configured for generating a spray curtain. In some examples, the spray bar is configured to generate a single spray curtain.
[0035] In some examples, the spray bar comprises one outlet for discharging wash liquid while, in other examples, multiple outlets. Conveniently, each outlet may be fitted with a spray nozzle for generating a specific spray curtain. Where the spray bar is arranged to generate a single spray curtain, suitably, the spray bar has a single row of outlets.
[0036] Following its insertion into the can washer, the spray bar may be secured in position. Suitably, in some examples the can washer comprises a locking mechanism which may engage the inserted spray bar in order to secure it in place.
[0037] In some examples, the locking mechanism is located on the access side of the can washer. Such an arrangement may be desirable as the spray bar is inserted from the access side and, hence, the locking mechanism may be engaged without delay.
[0038] In some examples, the locking mechanism is arranged to engage a cap end of the spray bar. The cap end of the spray bar, suitably, is the end opposite the inlet end. Conveniently, the locking mechanism may be engageable to secure the spray bar in position once fully inserted.
[0039] In some examples, the locking mechanism comprises a disengaeable bracket which is configurable to retain the spray bar.
[0040] It will be appreciated that a plurality of spray bars would typically be provided on each washer. A plurality of upper spray bars may be provided. The upper spray bars direct fluid from above a transport mat moving the cans through the washer. Additionally or alternatively, a plurality of lower spray bars direct fluid from below and through the transport mat.
[0041] According to another example, there is provided a method of changing a spray bar configuration.
[0042] The method comprises providing a can washer having a supply side and, opposite thereto, an access side.
[0044] The method comprises disengaging a locking mechanism provided on the access side and arranged to engage a capped end of the spray.
[0045] The method comprises pulling the spray bar from the can washer. This step comprises disconnecting the spray bar from the supply port located on the supply side and in flow communication with the supply manifold. This step further comprises removing the spray bar from the guide arranged to carry the spray bar, wherein the guide extends from the supply port at least halfway towards the access side.
[0046] Advantageously, replacement of the spray bar with a spray bar having a different configuration is improved. For instance, when processing cans of different sizes, spray bars having optimal nozzle pitch can be easily swapped between production runs. The washer can be provided with further process controls to optimise the spray generated by the spray bar. For instance, fluid characteristics and flow rate through the spray bar can be controlled. In particular, the spray bar may connect to a manifold exit or valve and the manifold may include a damper to control the fluid flow through said aperture or valve.
[0047] Although the improvements have been described in relation to a can washer, it will be appreciated that the easy replacement of spray bars may be applicable to other machines in the can production process where spray bars are used. Therefore the exemplary embodiments may apply to can production machines having a spray bar as explained in relation to a can washer having the spray bar.

DESCRIPTION OF EMBODIMENTS
[0049] At least some of the following example embodiments provide an improved can washer. The example can washer has a spray curtain configuration which is quickly and easily adapted. At least some examples may provide ease of access to an interior of the can washer for purposes such as maintenance and repair. At least some examples may provide generation of improved spray curtains. Many other advantages and improvements will be discussed in more detail herein.
[0050] Fig. 1 shows a perspective view of a can washer 100 for treating newly-formed cans through application of wash liquid.
[0051] The can washer 100 is fitted with means for carrying cans through the can washer. In this example, the can washer comprises a conveyor belt arranged to transport cans through the can washer. In this example, the can washer 100 has a housing of elongate shape and the conveyor belt is arranged centrally, operating along a longitudinal direction of the can washer. The cans may be inserted at a front end of the can washer for treatment and retrieved from a rear end of the can washer.
[0052] A first side of the can washer 100 corresponds to a supply side 110. In this example, the supply side is a first lateral side of the can washer. The supply side is devoted primarily to storage and distribution of wash liquid.
[0053] A second side of the can washer 100 corresponds to an access side 120. In this example, the access side is a second lateral side of the can washer and is located opposite of the first lateral side. Suitably, the access side enables access to an interior of the can washer. In this example, a removable access panel 121 is located on the access side for opening the housing.
[0055] The can washer 100 is suitable for generating spray curtains of wash liquid. Suitably, a supply manifold 130 is provided on the supply side. The supply manifold, or manifold, holds the wash liquid and supplies the wash liquid for treatment of the cans. In some examples, a plurality of supply manifolds is provided.
[0056] In some examples, the supply manifold 130 is filled with wash liquid from the access side 120. Suitably, a supply pipe is provided through which wash liquid may be transported from the access side to the supply side 110. In this example, the supply manifold is arranged to be filled from the supply side. Accordingly, a supply pipe need not be provided, thus resulting in a simplified piping network.
[0057] In some examples, wash liquid is sprayed onto cans being passed through from above as well as from below. In other examples, the can washer 100 is arranged to spray wash liquid only from above or below. In this example, the can washer 100 is arranged to spray wash liquid from above only. Suitably, a spray bar 140 for generating a spray curtain extends across the conveyor belt at a suitable elevation above the conveyor belt. Conveniently, the spray bar 140 is carried by a guide 150 extending across the conveyor belt on which the cans are passed through the can washer 100.
[0058] The spray bar 140 is configured to generate a spray curtain. Suitably, the spray bar is in flow communication with the supply manifold 130 during operation of the can washer 100. That is to say, wash liquid is fed from the supply manifold to the spray bar so that a spray curtain may be produced.
[0059] In this example, the spray bar 140 has a plurality of outlets 142 for discharging wash liquid. Suitably, the outlets are arranged to discharge wash liquid into the direction of the conveyor belt. In this example, the outlets are arranged to point into a generally downwards direction and, accordingly, discharge wash liquid into the downwards direction.
[0060] Conveniently, an outlet 142 may be fitted with a nozzle. Nozzles fitted to the plurality of outlets 142 may be arranged to generate an improved spray curtain. The improved spray curtain may be such that the cans are exposed to wash liquid for an effective treatment. Accordingly, the nozzles may be chosen dependent on the particular cans being treated, for example the size or shape of the cans.
[0061] When fitted to the outlets 142, the nozzles are arranged to spray the wash liquid into the downwards direction. Thus a spray curtain may be generated through which the cans are passed by the conveyor belt.
[0062] Fig. 3 shows a perspective view of a portion of an interior of the can washer 100 where the spray bar 140 is removed from the guide 150. For illustration purposes the spray bar is also shown in Fig. 3.
[0063] The exemplary can washer 100 is easily adaptable to modify a spray curtain generated by the can washer. Suitably, the can washer is configured for convenient removal and insertion of the spray bar 140.
[0064] In this example, the spray bar 140 may be removed from the guide 150 through an open end 152, or receiving end 152, of the guide. That is, the open end forms an opening. Conveniently, the open end is located in the vicinity of the access side 120. Suitably, the spray bar may be pulled from the open end of the guide in order to remove the spray bar from the can washer. Accordingly, the spray bar may be easily removable from the access side.
[0065] The guide 150 supports the spray bar at the open end 152 throughout the removal of the spray bar 140 from the can washer 100. Ease of removal may thus be provided, even where the spray bar has a relatively high weight and substantial length. Conveniently, the spray bar may be removed manually.
[0066] In this example, the guide 150 forms a sleeve 154 defining a passage 156. Suitably, the spray bar 140 is carried inside the passage. Conveniently, the spray bar is removable from the passage by pulling the spray bar from the passage.
[0067] In this example, the spray bar 140 has a substantially cylindrical shape. Suitably, the sleeve 154 defines a corresponding passage 156 arranged to receive the spray bar. In other examples, the spray bar has a different shape and the sleeve defines a corresponding passage.
[0068] Following removal, the spray bar 140 may be re-inserted or, as the case may be, a different spray bar 140 inserted. Suitably, the spray bar 140 may be pushed from the access side 120 for insertion of the spray bar. Conveniently, the spray bar may be inserted manually.
[0069] In this example, the open end 152 of the guide 150 extends to the access side 120. Conveniently, the open end may therefore receive and support the spray bar as it is being inserted. Insertion of the spray bar 140, therefore, may be improved.
[0070] Thus ease and convenience may be improved for adapting a spray bar configuration of the can washer 100.
[0071] When fully inserted the spray bar 140 is in flow communication with the supply manifold 130. Suitably, in this example the guide 150 extends from the supply manifold and is arranged to guide the spray bar to the supply manifold during insertion.
[0072] A supply port 132 is provided to receive the spray bar 140 and to feed, in use, wash liquid to the spray bar. In this example, the supply port 132 is provided on the supply manifold 130. In other examples the supply port may be provided separately and connected to the supply manifold through a suitable piping network.
[0073] Conveniently, the guide 150 is arranged to guide the spray bar 140 to the supply port 132 of the supply manifold 130 during insertion. Suitably, the spray bar 140 has an inlet end 144 for connection to the supply port and provides an inlet for wash liquid.
[0074] When fully-inserted, the inlet end 144 and the supply port 132 may connect through a male-female coupling. In this example, the inlet end of the spray bar 140 is configured to fit into the supply port 132. Conveniently, a suitable seal is engaged when the inlet portion is inserted into the supply port. For example, an O-ring arrangement may be provided such that an O-ring seals a gap formed between the inlet end and the supply port and through which wash liquid could escape during use.
[0075] In some examples, a locking member is provided to secure the spray bar 140. Suitably, the locking member may be engaged so that a fully-inserted spray bar remains inserted.
[0076] In some examples, the locking member comprises a bracket which may be engaged to secure the spray bar. Suitably, the bracket may engage a cap end 146 of the spray bar.
[0077] In some examples, the spray bar 140 has outlets 142 and/or nozzles which extend from a main body of the spray bar. In this example, the outlets 142 extend along a radial direction of the substantially cylindrical spray bar. Suitably, the guide 150 forms a slot 158 through which the outlets 142 may extend.
[0078] Suitably, the slot 158 extends from the open end 152 so that when the spray bar 140 is being inserted into the passage 156, the slot receives the outlets 142. Conveniently, correct alignment of the outlets may thus be ensured.
[0079] In this example, the outlets 142 are arranged in a row or on a substantially straight line. Suitably, the slot 158 is substantially straight so that the outlets may be received.
[0080] Fig. 4 shows a perspective view of a portion of an interior of the can washer 100 where the guide 150 is removed. For illustration purposes the guide is also shown in Fig. 4.
[0081] An interior of the exemplary can washer 100 is convenient to access in order to, for example, perform maintenance or repair work. Suitably, the guide 150 is removable from the can washer. Thereby the space occupied by the guide may be freed up and access to the interior of the can washer may thus be improved.
[0082] In this example, the guide 150 is removable. Suitably, the guide comprises a docking end 159 which is arranged to detachably couple to the supply port 132. Any suitable mechanism for coupling the guide and the supply port may be used. In this example, a bayonet fastening mechanism is used.
[0083] In this example, the docking end 159 of the guide 150 fits around the supply port 132. Conveniently, a pair of pins is provided on the supply port while a corresponding pair of slots is provided on the docking end. The pair of pins and the pair of slots, suitably, form a bayonet fastening mechanism. That is, the guide and the port are configurable so that the pins are received in the slots and retained therein.
[0084] In some examples, the can washer 100 comprises a support member arranged to support the guide 150. In this example, a support member may be provided to support the guide in addition to the supply port 132, where one end of the guide is supported, in order to reduce strain on the supply port. Suitably, the support member may be provided towards the other end of the guide. That is, the support member may engage the guide in the vicinity of the open end 152.
[0085] In some examples, the support member comprises a bracket which is configurable to engage and retain the guide.
[0086] In an exemplary embodiment, as shown in Figure 5, the can washer includes an upper spray bar 150u and a lower spray bar 1501. Both spray bars are suitably in accordance with the spray bar as herein described. The upper spray bar 150u directs fluid from above the mat transporting the cans. The lower spray bar 1501 directs fluid from below and through the mat transporting the cans.
[0087] In further exemplary embodiments it is envisaged providing the manifold 130 with a control damper. Here, the control damper is operable to control the fluid supplied to the spray bar 150. Any suitable damping method may be employed to control the fluid flow. For instance the damper may control an exit aperture to the spray bar by increasing or decreasing the aperture size in order to increase and decrease the flow rate of fluid into the spay bar and / or the pressure of the fluid entering the spray bar. For instance a stopper is arranged in the manifold and supported on a shaft that extends through the manifold to be operable by a user. The shaft is suitably sealed. Movement of the shaft controls the stopper to move towards or away from the exit to control the fluid flow there through.
[0088] According to one example, there is provided a method of changing a spray bar configuration of a can washer. The method comprises providing a can washer having a supply side and, opposite thereto, an access side.
[0090] The method further comprises disengaging a locking mechanism provided on the access side and arranged to engage a cap end of the spray bar.
[0091] The method further comprises a step of pulling the spray bar from the can washer. This step includes disconnecting the spray bar from a supply port located on the supply side and in flow communication with a supply manifold. This step further includes removing the spray bar from a guide arranged to carry the spray bar, wherein the guide extends from the supply port at least halfway towards the access side.
[0092] In summary, exemplary embodiments of a can washer have been described.
