Abstract
Description
- The present invention relates to a machine for banding groups of palletised products, in particular palletised loads consisting of stacked products (such as, for example, but not restricted to, packs of bottles or other containers) to undergo intermediate processes and to be transported from one factory to another or from one processing station to another).
- Machines of this type are used to wrap a band of material around a groups of palletised products stacked to a certain height and relatively light in weight, in such a way as to stabilise the stacks during transportation or normal handling in processing lines. Typically, the palletised load consists of bottle crates placed side by side and stacked in two or more layers.
- To stabilise a load of this type, the banding machine wraps a first band of plastic film at a certain height in order to hold the stack together at the most unstable part of it (usually the top of the stack) which would be the first to topple during transportation.
- Prior art machines that perform banding operations of this type comprise a portal frame whose uprights mount a pair of film rolls at a predetermined height. The film is unwound by suitable rollers in such a way that it is positioned transversely between the uprights to intercept the palletised load as the pallet moves under the portal frame on a conveyor.
- The forward motion of the pallet, after its front end has come into contact with the band of film, causes the rolls to unwind so as to wrap the band around the sides of the products stacked on the pallet. As soon as the pallet has moved past the portal frame, it is stopped and a unit comprising a sealer and a cutter, mounted behind the uprights, runs along the back of the palletised load on suitable supports in a direction parallel to the rear face of the load in such a way that the band of film is wrapped right around the load.
- In other words, the film forms a loop around the upper section of the palletised product load and, since the film used is usually stretch film, also has a tightening effect which holds the load together.
- At this point, the section of the band at the back of the palletised load is sealed and, as soon as this has been done, the cutter cuts the band half way between the two sealed ends: that means the looped band wrapped around the palletised load is closed, sealed and cut off, while the seal keeps the two rolls joined to each other by the remaining film positioned transversely between the two uprights and ready to intercept the next palletised load moving forward on the conveyor, thus ensuring that the process is not interrupted.
- An increasingly frequent requirement is for banding machines to apply to the palletised load a second band of film, lower down than the first and bearing a distinguishing mark, such as, for example, a label identifying the products transported, their factory of origin, or other information.
- To make applications of this type possible, the following have been added to banding machines:
- a pair of rolls mounted on the uprights of the portal frame and designed to wrap a second band of plastic film, to which labels can be applied, at a fixed height relative to the uprights themselves; and
- a second sealer and cutter assembly similar to the first assembly, and independent of it, mounted close to the base of the portal frame and mobile in synchrony with the first assembly by means of two additional arms, designed to seal and cut the second band in the same way as the first.
- This type of solution consists basically of a machine already well known in the trade used to apply a single band, with the simple addition of another pair of film rolls and a second, fixed, independent unit but without adapting its constructional philosophy to suit the new requirement.
- This type of structure has several disadvantages which have been overcome in a new solution proposed by the same Applicant as the present (see Italian patent application BO2002 A000232), in which the two sealing and cutting units are supported by a single mounting unit that projects from the portal frame and that slides along the frame crossbeam to and from the idle and working positions of the units: this solution has made the sealing and cutting units extremely, practical and adaptable to any type of production line in which the portal frame is used.
- This improvement has led to a widespread and increased use of labels applied to the plastic bands and bearing information such as product type, destination, origin, quantity, weight, etc.
- The labels, usually placed on three sides of the palletised load, are applied to the plastic band at a station located downstream of the banding machine and equipped with independent label application means.
- This type of configuration, however, tends to slow down the flow of the pallets that have already been banded to enable the labels to be applied and requires an independent, dedicated labelling station which increases the overall dimensions of the production line.
- The present invention has for an object to overcome the above mentioned disadvantages by providing a machine for banding palletised products that has a very compact structure, and is equipped with units for sealing and cutting the plastic band and for applying alphanumeric characters, all mounted in a single station that is quick and easy to adjust and operates in highly synchronised fashion.
- According to the invention, this object is achieved by a machine for banding individual, grouped or palletised products and comprising at least: a conveyor, extending in a direction of feed, for transporting the products; a frame mounted over the conveyor and equipped with at least two rolls of film mounted on the frame uprights in such a way as to form a band of film positioned transversely relative to the uprights so as to intercept the front of the products as they move forward; at least one unit for sealing and cutting the film, supported by the frame and mobile between an idle position, where the unit is close to the uprights, and a working position, where the unit is away from the uprights so that it intercepts, seals and cuts the portion of film band wrapped around the products; the machine further comprises at least one unit located in the vicinity of a section of the film band unwinding path and designed to apply at least one distinctive code to at least one part of the film band.
- The technical characteristics of the invention, with reference to the above objects, are clearly described in the claims below and its advantages are apparent from the detailed description which follows, with reference to the accompanying drawings which illustrate a preferred embodiment of the invention provided merely by way of example without restricting the scope of the inventive concept, and in which:
- Figure 1 is a side view, with some parts cut away to better illustrate others, of a machine according to the present invention for banding groups of palletised products;
- Figure 2 is a front view of the banding machine of Figure 1;
- Figure 3 is a top plan view of the banding machine illustrated in the figures listed above;
- Figures 4 to 6 are schematic top plan views illustrating a series of steps in the application of codes to a band placed round the groups of products in a machine according to the present invention.
- With reference to the accompanying drawings, in particular Figures 1 to 3, the machine according to the invention, denoted in its entirety by the
numeral 1, is used for banding, individual, grouped or palletised products. - More specifically, the machine is used, for example, for
palletised stacks 3 of products which have undergone intermediate processes and have to be transported from one factory to another or from one processing station to another. - For example, and without restricting the scope of the invention, the machine is used for banding palletised loads which consist of bottle crates placed side by side and stacked in two or more layers and which necessitate a band of film to stabilise them at the top, and another band of film bearing a series of identification codes at the bottom.
- The
machine 1 comprises aconveyor 2, aframe 4, here in the form of a portal, and a pair of sealing andcutting units 10 and 10'. Obviously, the fact that it comprises two sealing andcutting units 10 and 10' is a non-restrictive example of the solution according to the invention. - More specifically, the
conveyor 2 may consist of a roller conveyor or a conveyor belt extending in a direction of feed A and used to carry the pallets, each supporting astack 3 of the aforementioned products. - The
frame 4 is mounted over theconveyor 2 and is equipped, in this non-restrictive embodiment, with twopairs uprights frame 4. - The pairs of
film rolls film 9, 9' positioned transversely relative to theuprights product stack 3 as it moves forward (see Figure 3). - The upper band 9' is designed to stabilise the
stack 3, whilst thesecond band 9 usually has the twofold purpose of stabilising thestack 3 and presenting information or codes C relating to the products in thestack 3. - The
units 10 and 10' for sealing and cutting the bands offilm 9 and 9' are mounted, relative to the direction of feed A, at the back of theframe 4 and are mobile between: - an idle position, where the
units 10 and 10' are close to theuprights 7 and 8 (as shown in Figure 3); and - a working position, where the
units 10 and 10' are away from theuprights film bands 9 and 9' wrapped around theproduct stack 3. (as shown in Figure 2), leaving other portions of thebands 9 and 9' positioned transversely between theuprights next stack 3. - Still with reference to Figure 2, the sealing and
cutting units 10 and 10' are supported by asingle mounting unit 22 that projects from theframe 4 and that slides along thecrossbeam 4c of the latter to and from the idle and working positions (as indicated by the arrows F in Figures 1 and 2). - This structure is exhaustively described in Italian patent application BO2002 A000232 by the same Applicant as the present and will not therefore be described in further detail herein.
- The
rolls uprights rollers 23 for feeding and tensioning the respective bands offilm 9 and 9' being unwound so as to keep the bands of film properly tensioned when they are intercepted by theproduct stack 3. - Each of the
rolls carriage 24 coupled to a power drivenworm screw shaft 25 that enables adjustment in both directions along the respective upright 7 and 8 (see arrows F2): this permits adjustment of the position of thebands 9, 9' on thestack 3 according to the height of the stack. - The
banding machine 1 also comprises aunit 11, mounted in the vicinity of a section of the path P (shown in Figure 3) along which one of the two bands of film - the one labelled 9 - is unwound and designed to apply at least one distinctive code C to at least one part of theband 9 itself. - The code C may be any type of label or similar device including any combination of alphanumeric strings, graphics, symbols or logos or any other alternative reference systems such as bar codes.
- The
unit 11 may be mounted in the vicinity of one of the film rolls 5 and 6 (in this case it is the lower pair and the roll is the one labelled 6). Theunit 11 is equipped with a plurality ofrollers 12 forming the unwinding path P and defining at least one straight section of film facing the unit 11: in this way, the codes C can be applied to the part of theband 9. - Similarly (see dashed line in Figure 1), the
unit 11 may be mounted at the upper pair ofrollers - As shown in the accompanying drawings, the
unit 11 is mounted outside theframe 4, on one side of theframe 4. - As mentioned above, the pairs of
rolls unit 11 is equipped with vertical drive means 13 allowing theband 9 and the codeC application unit 11 to assume predetermined positions relative to each other. - Preferably, but without restricting the scope of the invention, the drive means 13 may synchronise the
unit 11 with the lower pair ofrolls - The drive means 13 may, purely by way of example, comprise a
beam mounting unit 14 for theunit 11, coupled with aworm screw shaft 15 that may be power driven or actuated manually by an operator in order to drive theunit 11 up and down in synchrony with therolls 5 and 6 (see arrows F11 in Figure 1). - As regards the type of codes C applicable to the
band 9, theunit 11 may consist of acustomary labelling unit 11e equipped withmeans 11m, a kind of application pad, designed to apply at least one label C to the band offilm 9. - The
labelling unit 11e may apply labels C made of paper or plastic, depending on working requirements. - In an alternative embodiment, the code
C application unit 11 may comprise means 11s (illustrated schematically in Figures 4, 5 and 6) for printing the codes C directly on the band offilm 9 being unwound. - Obviously, the
unit 11 is connected to a data processing and transmission system 30 (illustrated as a block in Figure 3) to enable theunit 11 to receive the codes C to be printed on theband 9. - Similarly, there may be
means 31 for controlling the unwinding of theband 9 and activating theunit 11 in accordance with the parts of theband 9 on which the codes C have to be printed: in practice, the parts where the codes C are to be applied are decided in accordance with the size of theproduct stack 3 and, hence, the length of theband 9 unwound before theunit 11 is activated. - Thus, the codes C to be applied to the
band 9 are generated while theband 9 itself is being unwound and printed on predetermined parts of the latter (as shown in Figure 1) calculated in accordance with the size of thestack 3 passing by. - For easy legibility of the codes C when the
stack 3 is in a warehouse or is being transported from one place to another, theband 9 may have three sets of codes C applied to it, positioned on thefront 3f, on oneside 3g and at theback 3r of thestack 3. - On the
side 3g andback 3r of thestack 3 the codes C are generated or applied to the predetermined part Z' during the step of feeding thestack 3 along theconveyor 2 while theband 9 is being unwound and in such a way that thestack front 3f intercepts thefilm bands 9 and 9' positioned transversally with respect to theuprights band 9 is performed preferably while theband 9 is moving normally, or it may be performed while theband 9 is slowed down slightly or stopped for a short length of time. Alternatively, depending on the type ofunit 11 used, theunit 11 may be made to move at the same speed as theband 9 being unwound and to generate and apply the codes as it follows theband 9. - The codes C on the
front 3f of thestack 3, on the other hand, are obtained by a step of generating the codes C prior to the step of feeding thestack 3. - As illustrated in Figure 4, the step of feeding the
stack 3 may be preceded by: - a step of moving the branch R of the
band 9 positioned transversally with respect to theuprights unit 11 that applies the codes C; - a step of generating at least the codes C on the part Z of the band 9 (see Figure 5);
- a step of further moving the branch R of the
band 9 by an amount sufficient to reposition the branch R between theuprights - These steps of moving the part z of the
band 9 towards and away from theuprights - A machine structured as described above therefore achieves the aforementioned objects by incorporating into the banding machine structure a code application unit in such a way that operations previously carried out at two different operating stations are now carried out at a single operating station.
- This architecture makes it possible to speed up stack processing without affecting normal banding time and with the advantage that the stacks have the codes assigned to them applied at the same time as they are banded.
- The incorporation of the code application unit into the banding machine eliminates the need for a labelling station downstream of the banding machine, thus saving time, space and money.
- The invention described has evident industrial applications and may be subject to modifications and variations without thereby departing from the scope of the inventive concept. Moreover, all the details of the invention may be substituted by technically equivalent elements.
