Definitions
- the present invention relates to an apparatus for packaging single or grouped products with heat-shrink film.
- the products may be parts of furniture units.
- a first solution (see patents IT-1.273.200 and IT-1.273.201 ) comprises two consecutive infeed and outfeed conveyors, lying in the same plane, which transport the products in a defined feed direction and which are separated by a vertical sealing device.
- a portal frame sliding in a direction parallel to the feed direction mounts at the top of it a plurality of heat-shrink film rolls arranged in pairs of different width.
- the pair of rolls used for wrapping the products is transported by the sliding portal frame to the wrapping area (that is, close to the film sealing device) and one of the rolls is then made to move below the product feed conveyor (thanks to the possibility of telescopically adjusting the conveyor).
- a second solution described in patent EP-939.031 , unlike the first solution described above, comprises a fixed portal frame mounting the pairs of rolls at the top of it, and means for guiding the selected film positioned directly on the infeed conveyor.
- the infeed conveyor retracts as far as the selected pair of rolls. One of the rolls moves down until it is below the level of product feed and the conveyor then moves back to its working position close to the outfeed conveyor.
- the film is tensioned by an overhead crossbeam supported by the end of the conveyor and a tensioning roller lower down associated with the end of the conveyor which together cause the section of film that will be intercepted by the products to be positioned vertically at the outfeed area in the vicinity of the sealing devices.
- the first solution has a rather complex and costly structure comprised of a large number of components such as a power-driven frame, parallel rails, etc.
- the machine has to be shut down even if only one pair of rolls has to be changed. Moreover, the rolls are located quite high up and when new, are very heavy, which means that changing them involves some risk and requires suitable lifting equipment (such as a hoist). The same applies to splicing the film web after the rolls have been changed. This operation, by which the free ends of the new pair of rolls are joined is also carried out at the top of the portal frame.
- the present invention therefore has for an aim to overcome the above mentioned drawbacks through an apparatus for packaging products with heat-shrink film having a simple structure which is safe and practical not only during operation but also when changing the film rolls, without reducing productivity and flexibility.
- an apparatus for packaging products with film comprising the following: a first and a second conveyor for transporting products along a feed line; the first conveyor is equipped with an end section that is adjustable in length so that it can move towards and away from the second conveyor; a portal frame positioned at the first conveyor and designed to mount a plurality of pairs of rolls; actuating means for moving a selected pair of rolls away from each other in a vertical direction in such a way as to position a section of film transversely to the feed line; means for guiding the selected film so it forms a broken-line configuration that is intercepted by the products; a part of the portal frame located under the first, infeed conveyor, is equipped with housings for accommodating respective pairs of film rolls; one of the rolls in each pair is fitted with actuating means that move it away from the other roll and raise it towards the top of the portal frame, that is to say, to a position above the first conveyor.
- the apparatus 3 may be used to package products 1 consisting of parts of furniture units.
- the apparatus 3 essentially comprises:
- infeed conveyor 4 As shown in Figures 1 and from 4 to 7, a part of the portal frame 6 located under the first, infeed conveyor 4 is equipped with housings 11 for accommodating respective pairs of film 2 rolls 7 and 8.

Abstract
Description
- The present invention relates to an apparatus for packaging single or grouped products with heat-shrink film. In particular, but without restricting the scope of the invention, the products may be parts of furniture units.
- Prior art machines of this type come in two different constructional types: a first solution (see patents
IT-1.273.200 IT-1.273.201 - A portal frame sliding in a direction parallel to the feed direction mounts at the top of it a plurality of heat-shrink film rolls arranged in pairs of different width. The pair of rolls used for wrapping the products is transported by the sliding portal frame to the wrapping area (that is, close to the film sealing device) and one of the rolls is then made to move below the product feed conveyor (thanks to the possibility of telescopically adjusting the conveyor). Once the film has been positioned vertically in this way, the products moving along the conveyor intercept the film and push it forward in such a way as to unwind it from the rolls and cause it to be drawn around the products as the latter continue moving forward.
- A second solution, described in patent
EP-939.031 - In practice, depending on size, the infeed conveyor retracts as far as the selected pair of rolls. One of the rolls moves down until it is below the level of product feed and the conveyor then moves back to its working position close to the outfeed conveyor. As the conveyor moves forward, the film is tensioned by an overhead crossbeam supported by the end of the conveyor and a tensioning roller lower down associated with the end of the conveyor which together cause the section of film that will be intercepted by the products to be positioned vertically at the outfeed area in the vicinity of the sealing devices.
- The solutions outlined above are not, however, free of disadvantages.
- The first solution has a rather complex and costly structure comprised of a large number of components such as a power-driven frame, parallel rails, etc.
- Further, in both solutions, changing the rolls positioned at the top of the portal frame is a troublesome task.
- The machine has to be shut down even if only one pair of rolls has to be changed. Moreover, the rolls are located quite high up and when new, are very heavy, which means that changing them involves some risk and requires suitable lifting equipment (such as a hoist). The same applies to splicing the film web after the rolls have been changed. This operation, by which the free ends of the new pair of rolls are joined is also carried out at the top of the portal frame.
- Consequently, the above machine configuration makes changing the film rolls a slow, arduous and even dangerous task. Changing even just a single pair of rolls thus involves considerable machine down time. The present invention therefore has for an aim to overcome the above mentioned drawbacks through an apparatus for packaging products with heat-shrink film having a simple structure which is safe and practical not only during operation but also when changing the film rolls, without reducing productivity and flexibility.
- According to the invention, this aim is achieved by an apparatus for packaging products with film and comprising the following: a first and a second conveyor for transporting products along a feed line; the first conveyor is equipped with an end section that is adjustable in length so that it can move towards and away from the second conveyor; a portal frame positioned at the first conveyor and designed to mount a plurality of pairs of rolls; actuating means for moving a selected pair of rolls away from each other in a vertical direction in such a way as to position a section of film transversely to the feed line; means for guiding the selected film so it forms a broken-line configuration that is intercepted by the products; a part of the portal frame located under the first, infeed conveyor, is equipped with housings for accommodating respective pairs of film rolls; one of the rolls in each pair is fitted with actuating means that move it away from the other roll and raise it towards the top of the portal frame, that is to say, to a position above the first conveyor.
- 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 schematic side view, with some parts cut away to better illustrate others, of an apparatus according to the present invention for packaging products with heat-shrink film; -
Figure 2 is a schematic front detail view, with some parts cut away, showing a unit forming part of the apparatus ofFigure 1 ; -
Figure 3 is a schematic top plan view, with some parts cut away in order to better illustrate others, showing a part of the unit ofFigure 2 ; -
Figures 4 to 7 are schematic side views illustrating a succession of steps by which the film is prepared by the apparatus illustrated in the drawings listed above; -
Figure 8 is a schematic top view of a part of the apparatus illustrated in the drawings listed above. With reference to the accompanying drawings, in particularFigures 1 and8 , the apparatus according to the invention, labelled 3 in its entirety, is used to package single or groupedproducts 1 with heat-shrink film 2. - In particular, but without restricting the scope of the invention, the
apparatus 3 may be used to packageproducts 1 consisting of parts of furniture units. - The
apparatus 3 essentially comprises: - a first and a
second conveyor products 1 along a feed line (indicated by the arrow A); thefirst conveyor 4, that is, the product infeed conveyor, is equipped with anend section 4a that is adjustable in length between a retracted position where it away from the end of the second, outfeed conveyor 5 (seeFigure 4 ), and an advanced position where it is close to the second conveyor 5 (seeFigure 5 ); - a
portal frame 6 positioned at the first conveyor 4 (when it is in the advanced position) and designed to mount a plurality of pairs ofrolls - actuating means 9 for moving the
rolls film 2 transversely to the feed line A when thefirst conveyor 4 is in the retracted position; - means 10 for guiding the
selected film 2 so it forms a broken-line configuration that is intercepted by theproducts 1 moving forward and when thefirst conveyor 4 is in the advanced position. - As shown in
Figures 1 and from 4 to 7, a part of theportal frame 6 located under the first, infeedconveyor 4 is equipped withhousings 11 for accommodating respective pairs offilm 2rolls - In this "low" configuration each
roll 8 of eachpair actuating means 9 which move it away from theother roll 7 so that, when selected, theroll 8 is raised towards the top of theportal frame 6, that is to say, above thefirst conveyor 4. - As clearly shown in
Figures 1 and8 , eachroll respective bin aforementioned housings 11. - Each
bin mounting rollers respective roll - In addition to this, each pair of
bins rolls rolls Figure 8 ) and an idle position in which the pair ofbins first conveyor 4 and the portal frame 6 (see dashed line inFigure 8 ). - At a structural level, the pairs of
bins wheels 17 on thelower bin 13 for sideways movement, whilst theupper bin 14 rests on thelower bin 13 and is locked to it, for example, by pins housed in respective holes made in the lower bin 13: in this way, when therolls bins new rolls - Obviously, the forward and return movement of the
bins - As shown in
Figures 1 ,2 and 3 , eachbin 14 containing theupper roll 8 of eachpair carriages 27, to respectivevertical guides 18 forming part of theportal frame 6 for moving theupper roll 8 in itsbin 14 vertically up and down. - Further, each
bin 14 containing anupper roll 8 is equipped with anindependent motor 19 acting on the pair ofrollers film 2 when it is intercepted by theproducts 1. - Similarly, each
lower roll 7 may be power-driven by arespective motor 7m acting on the pair ofrollers film 2 when selected. - For driving each
carriage 27 and hence therespective bins 14, the invention contemplates the provision of a kinematic drive system 20 (for example a transmission chain system) equipped with amotor 21 at the top of theportal frame 6, which together form the aforementioned actuating means 9. The aforementioned means 10 for guiding the film 2 (see alsoFigures 2 and 3 ), comprise at least one pair ofrods vertical drive carriage 27a, in particular with the carriages positioned at the zone of contact between themobile end 4a of thefirst conveyor 4 and the infeed end of thesecond conveyor 5. - Each of these
rods rods Figure 2 and the dashed line inFigure 3 ) and a working position in which therods selected film 2 when thefirst conveyor 4 is in the advanced position. - The
carriage 27a equipped with the guide means 10 has means 25 for engaging it with and disengaging it from therespective bin 14 containing theupper roll 8 so that therods mobile end 4a of thefirst conveyor 4, this forms a vertical section T of the broken-line configuration of thefilm 2 at the outfeed area of theportal frame 6. - For
carriage 27 modularity, each of thecarriages apparatus 3 is fitted with theaforementioned means 25 for engagement with and disengagement from therespective bin 14. - By way of example, the
means 25 may consist of a pair ofhooks 25a hinged to thesupport 27a of thecarriage 27 and rotationally driven about ahorizontal axis 25b (seeFigures 2 and 3 ) by respective means 25c, such as, for example, a cylinder. Thehooks 25a may be engaged inrespective slots 14a made in thecorresponding bin 14 below, so as to permit the vertical movement of the latter. - The
numeral 30 inFigure 1 denotes a customary unit for cutting and sealing thefilm 2 wrapped around theproduct 1, positioned between the twoconveyors portal frame 6. This unit secures thefilm 2 around the wrappedproduct 1 before the latter enters a shrink tunnel which stabilises the package. -
Figures 4 to 7 show how thefilm 2 is selected and prepared before the product to be packaged passes through. - First of all, the
first conveyor 4 is retracted (see arrow F,Figure 4 ) to leave a gap through which theroll 8 can pass as it moves upwards. - Next, the
carriages 27 of theselected roll 8 are actuated in order to raise the latter to its topmost position (see arrow F1,Figure 4 ). - At this point, the
first conveyor 4 is advanced until it is close to the sealing and cutting unit 30 (see arrow F2,Figure 5 ). The movement of thefirst conveyor 4 causes thefilm 2 to be intercepted and pushed as far as the aforementioned area, thefilm 2 being unwound in the process, if necessary using the motors on theselected rolls - Once this has been done, the
rods film 2 on both sides of the latter, in the vicinity of the sealing and cutting unit 30 (seeFigure 6 ), whilst thecarriage 27a that supports them is disengaged from thebin 14 below it by turning thehooks 25a. - Lastly the
carriage 27a carrying therods Figure 7 ), thereby forming the aforementioned vertical section T offilm 2 to form a C-shaped broken line with thefilm 2 so as to allow theproduct 1 to intercept thefilm 2 correctly as it passes. - An apparatus made in this way achieves the preset aims thanks to an optimised and practical portal frame structure that does not unduly encumber the machine as a whole.
- Placing the film rolls under the conveyor has undeniable advantages since, compared to prior art machinery of this kind, it is much easier, safer and quicker to change finished rolls of film without using special equipment.
- Another indubitable advantage of mounting the rolls in a low position is that they can be changed without necessarily shutting down the apparatus: in practice the rolls can be changed in "masked time". Yet another advantage of the configuration of the apparatus according to the invention is that the portal frame structure as a whole is lighter, which means the apparatus is much safer to work with.
- Furthermore, the apparatus according to the invention offers the same production quality and speed as prior art apparatus of the same kind.
- 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.
