Abstract
Description
- The present invention relates an apparatus for preparing wrapper elements or wrappers, for use preferably in a machine for wrapping a pasty, liquid or semi-liquid food product, and in particular, processed cheese.
- Prior art machines for wrapping processed cheese portions use a flat sheet of material, normally aluminium foil, which is folded into a shell-like shape to form the lower body of the wrapper which receives the processed cheese product and the top of which is then closed by a cover strip, also made of aluminium foil and appropriately attached to the wrapper body.
- In prior art machines for preparing the sheets so that each is ready to be folded to form the shell-like body of the wrapper, a web of aluminium foil is unwound from a roll and fed with stop-start motion. A cutting unit equipped with a blade having the shape of the wrapper to be made, cuts the individual wrapper sheets from the web. During one of the web stops, a single operation of the cutting unit creates a single wrapping sheet that will subsequently form the wrapper.
- As the wrapping sheet moves forward with stop-start motion, a tear strip and a label are applied to opposite faces of it. In practice, the device that cuts the tear strip from a corresponding reel of material places the tear strip directly on the wrapping sheet during one of steps of the stop-start feed motion in which the wrapping sheet is stopped. Similarly, the device that applies the label to the other side of the wrapping sheet places the label directly on the wrapping sheet during a corresponding stopping step as the sheet moves forward. Feeding the sheet of aluminium foil with stop-start motion in this way, however, results in low working speed.
- From a different viewpoint, another disadvantage of prior art machines is created by the complex procedures required at every changeover to synchronise the feed means of all the wrapper elements. Thus, when the length of the aluminium foil sheet, label and tear strip is changed, all the working parts used to transfer the foil sheets, labels and tear strips from the feed belt to the area where the foil sheets are folded to form the wrapper shells must be accurately re-adjusted.
- Moreover, it must be stressed that the prior art machines of the type described above, in addition to the means for arranging the wrapper sheets, may comprise devices for arranging labels and tear strips, or they may comprise devices for arranging only labels or only tear strips or they may comprise neither of these devices, in which case each wrapper consists of a sheet without either label or tear strip.
- The field therefore feels the need for a machine that can be easily set up according to the different configurations required by users of the machine.
-
EP 0601583 discloses the packaging of a packaged product which consists of a wrapping in the form of an outer coil on which a tear strip is attached and which is provided on a strip drum with rows of suction nozzles which are arranged obliquely offset and hold the tear strips, which have been cut off a web by means of cutting tool, and move them into contact with the web of film. - An apparatus for preparing wrapper elements or wrappers, in a machine for wrapping a pasty, liquid or semi-liquid food product, and in particular, processed cheese, comprising means for arranging the wrapper elements, or parts thereof, at least including means for dispensing the wrapper sheets; the apparatus being characterised in that it further comprises wrapper element feeding means between the arranging means and the transport means downstream.
- Thus, separating the operation of the dispensing means upstream from that of the wrapper forming means downstream, thanks to suitable intermediate feeding means, creates an extremely flexible machine structure that can easily be adapted to different user requirements.
- The invention also contemplates the provision of an apparatus comprising means for synchronising the wrappers or wrapper elements which is located upstream of the forming or wrapping zone of the machine.
- This eliminates the need to use more complex systems for adjusting the positions of the wrapper elements of the machine, and hence the need to plan down time for these adjustment operations to be performed.
- The other claims relate to other advantageous aspects of the invention.
- The technical characteristics and advantageous aspects of the invention 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 schematic perspective view of a first preferred embodiment of the apparatus according to the present invention; -
Figure 2 is a side view of the first preferred embodiment of the assembly apparatus according to the present invention; -
Figures 3 and4 are schematic perspective views of each of the longitudinal sides of the label dispensing means; -
Figure 5 is a side view of the device ofFigure 3 ; -
Figure 6 is a side view of a second preferred embodiment of the feed apparatus according to the present invention; -
Figures 7 to 11 schematically illustrate the steps in the operation of the feed means at the tear strip dispensing means; -
Figures 11 to 14 schematically illustrate the steps in the operation of the feed means at the wrapper sheet dispensing means; -
Figures 14 to 18 schematically illustrate the steps in the operation of the feed means at the means for sealing the tear strips to the wrapper sheets. -
Figures 1 and2 of the accompanying drawings show a first preferred embodiment of the apparatus, according to the present invention, for preparing wrapper elements or wrappers for a pasty, liquid or semi-liquid food product, in particular, processed cheese. - The apparatus according to the invention is designed in particular for assembling a
foldable sheet 12 made of suitable material, for example, aluminium foil, a linearly extending element orstrip 14 which is used for tearing the wrapper open and which is laid on one face of thesheet 12, and alabel 16, which is applied to the other face of thesheet 12, opposite the face to which thetear strip 14 is applied. The sheet and, if necessary, the tear strip, are then transferred to a forming station where they are folded into a shell-like shape to form a wrapper body suitable for receiving, at the following wrapping machine stations, a portion of pasty product which is then covered over and packaged in appropriate cartons together with other portions of the product. - This embodiment of the apparatus thus comprises means 18 for dispensing
wrapper sheets 12, said means consisting of a first and asecond conveyor belt 18 whosesurface 20 supports thesheets 12 thanks to its permeable structure or suitable holes connected to suction means for creating a negative pressure, or pressure below atmospheric pressure, in such a way as to hold thesheets 12 to it by suction. - As illustrated in
Figure 1 , the means for dispensing thesheets 12 are embodied preferably as first andsecond conveyor belts sheets conveyor belt 18 is trained aroundrespective end rollers sheets 12, and areturn section 18". - The apparatus further comprises means 22 for dispensing the
tear strips 14. The means for dispensing thetear strips 14 are embodied in first andsecond conveyor belts surface 24 supports thetear strips 14 thanks to its permeable structure or suitable holes connected to means for creating a negative pressure, or pressure below atmospheric pressure, in such a way as to hold thestrips 14 to it by suction. - The first and
second conveyor belts tear strips conveyor belt 22 is trained aroundrespective end rollers sheets 12, and areturn section 22". - The apparatus also includes means for dispensing the
labels 16, said means comprising aconveyor belt 26 whosesurface 28 supports thelabels 16 thanks to its permeable structure or suitable holes connected to means for creating a negative pressure, or pressure below atmospheric pressure, in such a way as to hold thelabels 16 to it by suction. Thisconveyor belt 26 is wide enough to feed two parallel rows oflabels - As shown, the
label dispensing belt 26 presents a first section 26' for receiving and feeding thelabels 16 towards feeding and assembling means 30, and areturn section 26"'. As illustrated, theconveyor belt 26 is trained aroundrespective end rollers labels 16 and a section for feeding and transferring them. Advantageously, the wrapper element feed means 30 are designed to sequentially receive and feed thetear strips 14 and theflat wrapper sheets 12 from the tear strip dispensing means 22 and the sheet dispensing means 26, in such a way that the elements remain centred, while following a circumferential path, relative to a defined centre line C of thereceiving seat 32. - Further, as illustrated, the sheet dispensing means 18 present a
respective end 18a extending in the proximity of the feed and assembling means 30 and anend 18b for receiving thesheets 12. - As illustrated in
Figure 1 , eachsheet receiving seat 32 presents a midpoint, relative to the circumferential feed direction, at which the centre or middle reference point of the corresponding sheet length is placed. The midpoints or centre lines C of the seats are located at equal intervals or distances P from each other in the direction in which the seats themselves move. Thus, the centre line C of eachseat 32 is equidistant from those of the seats adjacent to it by a length or distance P. It follows that sheets corresponding to large size wrappers will be positioned over theseats 32 with their transversal edges extending symmetrically beyond the lines where the transversal edges of sheets corresponding to smaller size wrappers would lie. - For centring the sheets corresponding to each wrapper size in this way, it is sufficient to act on the dispensing means either by adjusting them or by providing them with suitable means for retaining and dragging the sheets on the
conveyor 20, releasing them at a suitable point, in such manner as to increase the distance "d" between the sheets for smaller size wrappers. As illustrated, the feed means are preferably revolving means, embodied as a revolvingwheel 30, having asurface 32 that supports thetear strips 14 and thesheets 12 thanks to its permeable structure or suitable holes connected to means for creating a negative pressure, or pressure below atmospheric pressure, in such a way as to hold thesheets 12 to it by suction. - The
means 22 for dispensing thetear strips 14 also present arespective end 22a extending in the proximity of the feed and assembling means 30 at a receiving point which, in the direction of motion of the assembling means 30, is located upstream of the point where thesheets 12 are dispensed. Thus, eachsheet 12 is placed on the assembling means 30 on top of thecorresponding tear strip 14. - Similarly, the
means 26 for dispensing thelabels 16 present arespective end 26a extending in the proximity of the feed means 30 at a point downstream of the point where thesheets 12 are received. - Advantageously, the
retaining surface 32 of the feed means 30 moves continuously at a predetermined tangential speed V0. In practice, thewheel 30 revolves at a constant angular speed such that the upper surface of each tear strip moves at a speed equal to V0. - Also the
means 22 for dispensing thetear strips 14, themeans 18 for dispensing thesheets 12 and themeans 26 for dispensing thelabels 16 move at a predetermined speed corresponding to the speed V0 of the feed and assembling means 30 so that thetear strips 14, thesheets 12 and thelabels 16, respectively, reach the point where they are transferred to the feed and assembling means 30 in synchronised fashion as therespective sheets 12,tear strips 14 andlabels 16 are passing by. At the moment of transfer, the suction which is holding thesheets 12,tear strips 14 andlabels 16 against the respective retaining surfaces of the corresponding dispensing means is switched off. - As mentioned above, when changing over to a different wrapper size, the longitudinal spacing between
successive tear strips tear strips means 30, described in more detail below. The dispensing points where the feed means 30 receive thetear strips 14 and thesheets 12 are spaced in such a way that eachsheet 12 is associated with acorresponding tear strip 14. - The dispensing point of the
labels 16 is located, relative to the direction of motion of the feed and assembling means 30, downstream of the dispensing point of thesheets 12 at a distance such that eachlabel 16 is associated with thecorresponding sheet 12. - Each
label 16 is placed over the correspondingsheet 12, which is already on atear strip 14, coming to rest and being fixed to the face opposite the face that is in contact with the retainingsurface 32 of the assembling means 30 and that is on top of thecorresponding tear strip 14. - The invention also contemplates the provision of
means 34 for transferring the assembledwrappers 17 to a unit 35 for forming or folding the wrappers. - These transfer means 34 receive the wrappers which have been assembled in the assembling means and feed them at a predetermined speed V0 equal to the speed at which they are fed by the wrapper forming or
folding unit 33. - As illustrated, the means for transferring the assembled wrappers comprise at least one
conveyor belt 34 whoselower surface 36 retains the assembledwrappers 17 thanks to its permeable structure or suitable holes connected to means for creating a negative pressure, or pressure below atmospheric pressure, in such a way that the assembledwrappers 17 are held to the retainingsurface 36 by suction. As illustrated, themeans 34 for transferring the assembledwrappers 17 are designed to feed the assembledwrappers 17 in a first and a second parallel rows. - The assembled wrapper transfer means 34 have a section 34' that receives and feeds the assembled
wrappers 17 to the formingunit 33 to which it transfers each assembled wrapper 17 - from above - by switching off the retaining suction when thewrapper 17 reaches the formingunit 33 and the latter is ready to receive it. - The
conveyor belt 34 is trained aroundrespective end rollers labels 16, and areturn section 34". - Means which are not illustrated in the accompanying drawings are provided for adjusting the predetermined speed V0 of the assembling means 30 and of the
means unit 33 for folding thewrappers 33. - Further, for enabling the passage of the assembled
wrappers 17 from the assembling means 30 to the transfer means 34, means 26" are provided. - The means for passing the assembled
wrappers 17 are advantageously defined by asection 26" of thelabel 16 dispensingconveyor belt 26 downstream of the section 26' that receives and feeds thelabels 16 to the assembling means 30. - As illustrated, the
section 26" for passing the assembledwrappers 17 is trained around theroller 27b and athird roller 27c so as to form a conveyor belt that follows a triangular path. Thesection 26" for passing the assembledwrappers 17 receives the latter, from above, from the feed and assemblingwheel 30 at a point substantially coinciding with the point at which thelabels 16 pass. - In practice, the
labels 16 are pressed and glued to thewrapper sheets 12. Immediately after this, the retaining suction on thewheel 30 is switched off and the assembledwrappers 17 are passed to thesection 26" of theconveyor belt 26, which holds the assembledwrappers 17 to its upper retaining surface by suction and then passes them on to the transfer means 34 by switching off the suction. -
Figures 1 and2 also show means, denoted in their entirety by thereference numeral 38, for cutting the tear strips 14 from tapes, labelled 15, oftear strip 14 material unwound from a reel 15' and from areel 15" for each tear strip. Thesetear strip 14 cutting means are designed to place the tear strips 14 on the dispensing means 22 at the end of the latter opposite the end where the tear strips 14 are transferred to the assembling means 30. - The means 38 for cutting the tear strips 14 are advantageously positioned between the
means 22 for dispensing the tear strips and themeans 34 for transferring the assembledwrappers 17, thus reducing the overall size of the apparatus. - The cutting means consist, for each
conveyor belt 22, of a suitably shaped blade (not illustrated in the accompanying drawings) driven towards the correspondingbelt 22 in such manner as to cut thetear strip 14 and then away from thebelt 22 to enable the latter to continue moving forward. The tear strip dispensing means 22 are driven at a speed such that the tear strips move at the same speed as the assembling means 30 and can be transferred to the assembling means 30, drive being intermittent so that the belt stops when the tear strips 14 are received from the cutting means 38. - Once the tear strips 14 have been cut, the
conveyor belt 22 is accelerated to rapidly reach the speed at which the tear strips 14 are delivered to theassembling wheel 30. After delivering the tear strips to thewheel 30, theconveyor belt 22 is decelerated and rapidly stopped to enable other tear strips to be cut. - In the event of a wrapper size changeover, the tear strip cutting means are shifted lengthways along the corresponding
belt 22 so as to adjust the longitudinal spacing betweensuccessive tear strip - The apparatus according to the invention may comprise suitable means for cutting the
sheets 12 from a web of material forwrapper sheets 12. These means are not illustrated in the accompanying drawings and may have the form defined in Italian patent application No.BO2000A00037 - Means 40 are also provided for sealing the tear strips 14 to
respective sheets 12. Advantageously, the means for sealing the tear strips 14 torespective sheets 12 take the form of a revolvingheating roller 40 that is kept in contact with the surface of the feed and assembling means 30 that retains the tear strips 14 and thesheets 12 in such manner as to heat thesheets 12 placed over the respective tear strips 14. In this manner, continuous sealing of the tear strips 14 to thesheets 12 is achieved. - For sealing the tear strips, the sealing means 40 are designed to contact each
sheet 12 at a point which, in the direction of motion of thetear strip 14 assembling means 30, is located downstream of the points where the tear strips 14 and thesheets 12 are dispensed. The provision of suitable means for feeding and assembling the wrapper elements, which receive sequentially the various preformed elements of the wrapper and whose feed motion is continuous or substantially continuous, makes it possible to achieve machine operating speeds that are on average higher than the speeds attained by prior art feed devices with stop/start motion. Machine productivity, in terms of number of wrappers made per unit time is appreciably greater than that of prior art feed devices with stop/start motion. - The apparatus according to the invention further comprises means for applying glue to the
labels 16. The glue application means comprise twoelements labels labels 16 are fed by thelabel 16 dispensing means and at which the application elements rotate are such that two longitudinally successive labels are fed to eachglue application element 42. - As illustrated, these means comprise a pair of
glue application devices labels - As shown in particular in
Figure 2 , the glue application means comprise aglue application device 41 with aglue application element 42 havingmeans 44 for dispensing the glue to thelabel 16 and means for driving the glue dispensing means 44', 44" designed to make the glue dispensing means 44', 44" follow a glue dispensing path parallel to and at the same speed as the path followed by themeans 26 for feeding thelabels 16 in the section where the glue is applied to them. - As illustrated, the glue dispensing means in this particular embodiment are glue emitting nozzles 44', 49" connected by
respective conduits 45 to aglue tank 47. - More specifically, each glue application element has a single nozzle 44' at the front and a pair of
nozzles 44" at the back - only one of which is shown in Figure 20 - each of which puts a spot of glue on the blank face of thelabel 16 to be applied to wrapper sheet. - The means for driving the glue dispensing means comprise a
plate 46 for mounting the glue dispensing means 44', 44". The drive means move theplate 46 along a closed path having one section parallel to thelabel 16 feed belt. The plate is carried bybelts 48 carried on a firsttoothed wheel 50 and a secondtoothed wheel 52, longitudinally spaced from each other and equidistant from thelabel 16feed belt 26. - Two pairs of these
wheels respective belts 48 along a forward section and return section, enabling the mountingplate 46 to be kept parallel to thelabel 16 dispensing means. The first andsecond elements plate 46 that moves along a closed path. - The
glue application elements labels 16 are fed by thelabel 16 dispensing means and at which theapplication elements glue application element 42. - This glue application system has a simple structure and low cost. This glue application system is also easy to inspect. The apparatus according to the invention also comprises means for transferring the
labels 16 to the means for dispensing thelabels 16. - These transfer means comprise means for housing a plurality of
labels 16 which, as can be seen inFigure 1 , include first and second tubes for housing thelabels 16, the tubes being arranged in pairs in such.a way as to feed corresponding rows oflabels Figure 2 , the housing tubes are labelled 54.Figure 2 shows only one of each of the pairs oftubes 54. - As illustrated, the
label 16 housing means advantageously comprise a plurality of pairs oftubes 54, longitudinally spaced in the direction, in which thelabels 16 are fed by the dispensing means 26. Each pair of tubes is designed to feed corresponding labels 16. - It is thus possible either to feed different types of labels for different types of cheese or other pasty product to be wrapped or to create a larger, longer-lasting supply of labels in the label reservoir.
- The
labels 16 are stacked inside thetubes 54 which have an openlower end 54a designed to feed thelabels 16 out one at a time. Means 56 are provided for picking up thelabels 16 from the respective pair of label housing tubes and transferring them to themeans 26 that dispense thelabels 16. -
Figures 3 ,4 5 schematically show that the pickup and transfer means 56 of thelabels 16 comprise means for gripping thelabels 16 which, for each label tube, comprise alabel 16gripper element 58 having anend surface 59 for supporting and retaining arespective label 16 and drive means for moving the gripping means between a position where a label is picked up from the housing means 54 and a position where the label is transferred to the dispensing means 26. - More specifically, these label pickup and transfer means constitute means, as described in more detail below, for transferring the labels to continuously moving means.
- As can be seen also with reference to
Figure 5 , the retainingsurface 59 features suitable holes FE (or otherwise it is a surface permeable to air) connected to means for creating a negative pressure, or pressure below atmospheric pressure on thesurface 59, in such a way as to hold thelabels 16 to it by suction. The means for driving the gripping means consist of a revolvingdisk 60 positioned at a level substantially ranging in height from the labeloutfeed end 54a of the housing means 54 to the dispensing means orconveyor 26 of thelabels 16. - The
disk 60 mounts themeans 58 for gripping thelabels 16. As illustrated inFigure 3 , thelabel gripping element 58 takes the form of an L-shaped body connected at 58a to thelabel transfer disk 60 that supports and transports it. Thelabel gripper element 58 comprises aportion 58b, which connects it to the revolvingmeans 60, and aportion 58c, which is attached to theportion 58b and which defines thelabel pickup surface 59 with the holes FE connected to the suction conduits constituting the means for retaining the label E. - As illustrated, the
portion 58c projects outwards in a direction transversal to the supportingportion 58b. Further, the L-shapedbody 58 for gripping and supporting the labels is pivoted at 58a to the drive disk or means 60. - Means 62 are provided for moving the
label 16 grippingelement 58 between an outside extended radial position and an inside retracted radial position. - The outside extended position of the gripping
means 62 is created when themeans 58 are moved to thelabel reservoir 54 and to thelabel feed belt 26 to define, respectively, a position of picking up and a position of transferring a label. - The drawings show only the position where the label is transferred to the
conveyor belt 26. - During their movement from the
label reservoir 54 to theconveyor belt 26, thelabel gripping means 58 are kept in the retracted position which enables the label to be held more securely. Thelabel gripping means 58 are also kept in the retracted position during their movement from theconveyor belt 26 to thelabel reservoir 54 after the label has been released onto thebelt 26. - The outside extended position of the
means 58 when they reach thereservoir 54 enables them to pass the edge 54'a of the reservoir so that the retainingsurface 59 is close to the lower edge 54'a of thereservoir 54 and the lowermost label in thereservoir 54 can be extracted by the suction through thelabel supporting surface 59. - Once the
end surface 59 of theelement 58 has been positioned between the walls of thelabel reservoir 54 causing the end to protrude from thereservoir 54 and enabling thenext edge 54"a of the lower edge of the reservoir to be past, thelabel gripping element 58 is radially retracted. For transferring the label to theconveyor belt 26, theelement 58 is moved outwards so as to impinge on thebelt 26. The means for moving the gripping element between an extended position and a retracted position comprise acam profile 62 that acts in conjunction with a correspondingportion 64 of an L-shapeddrive lever 63, in this particular embodiment, aroller 64, pivoted at 64' to the L-shapedlever 63 at theend 63b of the latter. Thedrive lever 63 is pivoted to and supported by thetransfer disk 60 at 63a at the bend in the L-shapedlever body 63 and has another portion 63c with acurved rack 65 on the end of it which is designed to mesh with the teeth 67' of apinion 67 attached to the supportingportion 58b of thelabel pickup portion 58c, in such manner that rotation of thelever 63 caused by thecam 62 imparts rotational motion about thepin 58a on theelement 58 and radial motion on thelabel pickup surface 59. - The connecting means created by the
rack 65 and thepinion 67 define a gear ratio that can be appropriately chosen so that small radial movements of thecam follower roller 64 on thecam 62 cause a desired large radial movement of thelabel pickup surface 59. Thus, the overall dimensions of the device are advantageously limited. - Means are provided for moving the
cam 62 between an outside extended radial position and an inside radial position. - The means for moving the
cam 62 between an outside extended radial position and an inside transfer position take the form of acrank 66 connected by alink 68 to the base 62' which bears thecam 62 and which is coaxially housed in a circular opening made in thedisk 60, thus creating a structure of limited width. - In practice, in a first working condition, where a label is extracted from the label reservoir, the
disk 60 is stationary and thepickup element 58, with suction on, is positioned at thelabel 16housing tube 54 and sucks thelabel 16 out of the tube. - Starting from this position, the
crank 66 rotates and, through thearm 68, imparts rotation on thecam 62, whose profile forms a radial protrusion that causes thepickup element 58 to retract radially by rotating about the connectingpin 58a pivoted to thedisk 60. At this point, thedisk 60 turns by 180° dragging thepickup element 58 along with it, thus carrying thelabel 16 to the position shown inFigure 3 . During this step, thecam 62 remains in substantially the same position relative to thedisk 60, that is to say, it rotates with the disk so that thelabel pickup element 58 remains in the retracted condition. - When the
label pickup element 58 reaches theconveyor belt 26 below it, and while thedisk 60 continues to rotate, thecam 62 pushes thepickup element 58 outwards and imparts on theend surface 59, which is carrying the label, a speed corresponding to the speed of theconveyor belt 26, thus enabling a "running" transfer of the label, that is to say, enabling the label to be released by thepickup surface 59 onto the dispensingbelt 26 while thebelt 26 is in motion. The label is dropped by switching off the suction at theend surface 59 of thelabel pickup element 58. - Next, by an opposite movement to the pickup movement, the
cam 62 is rotated in such a way as to cause theend surface 59 of theelement 58 to retract, and thedisk 60 turns by 180°, taking thepickup element 58, now without a label on it, back to thelabel reservoir 54. - During this step, the
cam 62 remains in substantially the same position relative to thedisk 60, that is to say, it rotates with the disk so that thelabel pickup element 58 remains in the retracted condition. At this point, thecam 62 rotates while thedisk 60 remains stationary, thus enabling the pickup element to be inserted into thelabel reservoir tube 54 to extract anotherlabel 16. - The label arranging means described above place the labels at regular intervals, that is to say, with predetermined spacing, so that the distance between the ideal centres or reference points of the labels (corresponding to the spacing), which corresponds to the ideal centre distance or spacing of the wrapper sheets in the sheet dispensing area on the assembling means, is always the same, whatever the size of the wrappers. This means that the system can handle labels of different sizes, for different wrapper lengths, the labels always being in a centred position when they reach the area where they are dispensed to the assembling means 30.
- The next set of drawings illustrate another embodiment of the apparatus for preparing wrapper elements or wrappers, for use preferably in a machine for wrapping a pasty, liquid or semi-liquid food product, and in particular, processed cheese.
- This second embodiment of the apparatus according to the invention comprises means for arranging the wrapper elements, or parts thereof,, including means 122 for dispensing, in particular, tear strips, that is, elements used to tear the wrappers open, said means consisting of cutting means comprising first and
second cutting elements consecutive seats 132 of the wrapper feed means, as described in more detail below. - The cutting
elements - The cutting means take the form of a
blade 138 designed to cut the tear strip from atape 115 of suitable material. -
Means 139 are also provided for driving the cutting means 138, in alternating fashion, between a retracted position where the tear strip material is fed to the cutting means 138, and a forward position where the tear strip is cut and transferred to the feed means of this embodiment. - More specifically, the cutter blade drive means comprise a stem 139' which bears the
cutting blade 138 on the end of it. - The tape of tear strip material is unwound from a reel 115'.
- In this embodiment, the cutting elements are of the same type and are used to cut identical tear strips. In simple terms, the cutting elements are suitably oriented relative to the respective base, that is to say, in a direction substantially opposite the direction in which the wrapper elements are fed, in such manner that the tear strips placed on the
seats 132 are arranged according to an X or Y-shaped configuration. - Downstream of these tear strip dispensing means, there are means for dispensing wrapper sheets, said means comprising a revolving
roller 118, with suction holes or grooves 118', which feeds the wrapper sheets with continuous or substantially continuous motion. - More specifically, the dispensing means or
roller 118 preferably moves at a constant or substantially constant angular speed. - These wrapper sheet dispensing means make it possible to attain high operating speeds.
- The web 112' of wrapper material, normally aluminium foil, slides over the roller. The individual wrapper sheets, after being laterally shaped are cut transversely from the web.
- Downstream of the sheet dispensing means, there are sealing
means 140 designed to seal the wrapper sheets to the tear strips and consisting of aplate 140 with a fixedheated contact surface 141. - Alternatively, a sealing plate that remains in contact with the wrapper elements to be sealed while moving along with them for a certain length in the direction of feed might also be contemplated.
- Downstream of the sealing means, there are means for dispensing labels which comprise means for feeding the labels consisting of a
conveyor belt 126 driven continuously or substantially continuously at a constant speed so that high operating speeds can be attained. - As illustrated, the
conveyor belt 126 has an inclined section 126' that makes an angle B with the vertical. This limits the overall dimensions of the apparatus and creates means for assembling the label to the wrapper sheet at anend area 126a of the inclined section of the label feed belt. - Thus, the label is received on a
section 126b located upstream of the assembly point and being provided, at anarea 126c following the label positioning area between the point where the label is received and the assembling point where it is applied, with adhesive used for gluing the label to the bottom of the wrapper sheet. The label is picked up from areservoir 154 and placed on theconveyor belt 126 at predetermined intervals by suitable means such as those of the embodiment described above. - This creates a simple structure and, more specifically, makes it possible to reduce the length of the wrapping machine.
- Further, the label feed means also constitute means for transferring the wrapper element to the
means 134 that convey it to the wrapper forming, filling and sealing means of the processed cheese wrapping machine through a short, upperhorizontal section 126d located downstream of the inclined section where the wrapper element is received. - According to another aspect of it, between the means for preparing the wrappers and the downstream conveyor means 134, the present invention contemplates the provision of
means 130 for feeding the wrapper element and comprising a plurality of receivingseats 132 located at intervals of predetermined length P. - Thanks to these intermediate feed means, the wrapper elements can be positioned at predetermined intervals from each other upstream of the wrapper forming area, whatever the size of the wrappers. Thus, when changing over to a new size in a machine equipped with the apparatus according to the invention, it is not necessary to re-adjust all the wrapping parts, as is the case with prior art machines where practically all the working parts must be adjusted and re-timed.
- This means that, compared to prior art machines, changeover down time is eliminated. According to yet another aspect, the apparatus according to the invention constitute feed means for synchronising the wrappers or wrapper elements upstream of the forming or wrapping zone of the machine.
- Advantageously, the working motion of the feed means 130 is continuous or substantially continuous, thus making it possible to attain higher working speeds than those possible in prior art.
- The feed means according to the invention comprise means 132 for supporting the wrapper element and/or a part of it and consisting of a plate with a
surface 132a that supports the wrapper or wrapper element and that is equipped with suitable retaining means consisting of suction means designed to hold the wrappers or wrapper elements to the supportingsurface 132a. - Advantageously, the
means 132 for supporting the wrappers or wrapper elements are moved by feed means 133 consisting of a revolvingwheel 133 that moves continuously or substantially continuously at a constant speed. This wheel configuration minimises the space occupied by the apparatus in the wrapping machine. - Means are also advantageously provided for moving the supporting means relative to the
means - The means for moving the supporting means move, in particular relative to the feed means 133, between a retracted position, illustrated, for example in
Figures 7 and11 , which show a step before the tear strip is received up and a step after the tear strip is received by the supportingsurface 132, and an extended working position illustrated, for example inFigures 8 ,9 and10 , where the wrappers or wrapper elements are carried to a working end of the arranging means. - In practice, in a first advantageous working condition, the means for moving the means for supporting the wrappers or wrapper elements are designed to keep the supporting means in a condition such that they are stationary relative to the working means "outside" the feed means, whilst the feed means 133 themselves impart on the supporting means 132 a continuous motion at constant angular speed. This means that the required operation can be performed in the optimum manner without interrupting the feed motion, thus making it possible to attain high working speeds.
- More specifically, as illustrated in
Figures 8 to 10 , the means for moving the supportingsurface 132 are designed to keep the supporting surface in a condition such that it is stationary relative to the tear strip dispensing means 138 at a certain distance from the transfer end of the tear strip dispensing means whilst the feed means 133 carry on moving. This eliminates the need for intermediate means between the tear strip cutting means and the tear strip receiving means. - The means for moving the means for supporting the wrappers or wrapper elements are designed to rotate the supporting means, as illustrated schematically in
Figures 12 to 14 , in contact with a corresponding working surface of the revolving means 118 for dispensing the wrapper sheets so that the wrapper sheets are picked up continuously from the dispensing means while the feed means 133 carry on moving with continuous motion at a constant or substantially constant angular speed. Thus, the part facing the supportingmeans 132 is contacted in the optimum manner. - The means for moving the means for supporting the wrappers or wrapper elements are designed to keep the supporting
means 132, as illustrated schematically inFigures 15 to 18 , in a condition such that they are stationary and in contact withmeans 140 for sealing the tear strips to the wrapper sheets, while the feed means 133 carry on moving with continuous motion at a constant or substantially constant angular speed. Thus, the sealing surface is always the same size and can be heated more efficiently, with a lower power requirement to reach the optimum temperature for sealing. - According to yet another aspect, the means for moving the means for supporting the wrappers or wrapper elements are designed to keep the supporting means 132 in a condition such that they are parallel to a corresponding surface of the label feed means 126, the surface of the supporting plate of the supporting means following the same linear movement as the label feed belt. All this is carried out while the feed means 133 impart on the supporting means 132 a continuous motion at constant angular speed.
- During this step of transferring the assembled wrappers, the suction that holds the wrappers to the supporting means is switched off so that the wrapper sheets can be released and transferred to the conveyor means that carry them downstream towards the forming area where the wrapper is completed.
- As illustrated, the means for moving the supporting means, comprise a first supporting
arm 135 and a second supportingarm 137 which are linked in articulated fashion at theends means 132 for supporting the wrapper element and at the other ends 135b, 137a to the feed means 133 in such a way that the supporting means 132 move in parallel with the feed means so that they can receive a wrapper or wrapper element from the feed means in a suitable manner. - The invention also contemplates the provision of means, which are not illustrated in the accompanying drawings, for rotationally driving the
arms - The means for linking the feed means comprise means for driving the articulation pins 135c, 137c of the supporting
arms lever 139 and a second linkage consisting of acircular plate 141 rotatably retained within a respectivecircular seat 141 in the feed means 133. - At their
ends other ends articulation pin 143 fixed to the feed means 133. - Means which are not illustrated in the accompanying drawings are provided for driving the first and second linkages or drive means between a position in which the arms are in the conveying condition and a position in which the arms are in the pickup condition.
- In practice, driving both linkages in opposite angular directions adjusts the radial position of the wrapper or wrapper element relative to the arranging element, driving one or both linkages in the same angular direction through a suitable angle suitably variable over time causes the supporting plate to rotate, and appropriately combining the movements of the linkages and of the wrapper element holding arms creates the desired operations described above.
- Thus, the structure of the drive means is such that the wrapper element holding means can perform all the movements required for each operation.
- As illustrated, the feed means according to the invention constitute advantageous means for assembling and synchronising the wrapper elements with each other.
- Thus, the machine can be easily adapted to different types of wrappers: for example, wrappers with or without tear strip, without requiring significant changes to machine structure.
- In the apparatus according to the invention, the provision of suitable means for feeding the wrapper, which sequentially receive the wrapper sheets and place them in suitably spaced seats, and where the motion of the feed means is continuous or substantially continuous, makes it possible to makes it possible to achieve machine operating speeds that are on average greater than the speeds attained by prior art feed devices with stop/start motion. Machine productivity, in terms of number of wrappers made per unit time is appreciably greater than that of prior art feed devices with stop/start motion.
- In the apparatus according to the invention, the provision of suitable feeding and assembling means having seats for sequentially receiving the wrapper elements, which are suitably spaced at predetermined intervals and where the wrapper elements are centrally positioned permits the creation of wrappers which, whatever their size, are always in the correct feed and working position for the machine units downstream but without requiring the use of complex systems for adjusting the relative positions of the machine units.
- The other claims define other advantageous aspects of the invention.
- It will be understood that the invention can be adapted and varied in several ways without thereby departing from the scope of the inventive concept. Moreover, all the details of the invention may be substituted by technically equivalent elements.
