Definitions
- the present invention relates to an enhanced palletizer apparatus, in particular an apparatus designated to consolidate large tiles on a pallet in view of the subsequent packaging and/or use on building sites.
- a palletizer is an apparatus that serves to stack in an automatic way on a pallet, a series of products for the subsequent packaging.
- the transfer operation of a plurality of products from a production line to one or more pallets, with an accurate and orderly stacking, can be very tiring and burdensome when carried out manually.
- each of the products - in particular, in the context of the present application boxes each containing a plurality of tiles - must be picked up individually and transferred to one of a plurality of loading pallet, the pallet being chosen (preferably in an automatic way) for example depending on the batch or to the dimensions of the product.
- the various pallet waiting to be loaded are distributed along a line located in an area next to the end of the production line, which implies considerable displacements.
- palletizer equipment which comprise one or more gripping heads movable on suitable raised guides, suitable to pick up the individual products and transfer them quickly on the pallets to be loaded, arranging the individual products into the appropriate position in the stack on the pallet.
- the system provides an appropriate signal (acoustic and/or visual) to the operator, who can thus remove the loaded pallet, replacing it with an empty one, and send it on to the next step of packaging (typically performed by heat-shrink or stretch plastic film).
- IT1408944 in the name of the same Applicant, suggests to lay progressively the packaging boxes in the upright position, one next to the other, by applying strapping loops between the already arranged material and the new load gradually added.
- This work mode - that can be similarly applied to boxes comprising few tiles or to individual products - has a series of advantages and has resulted therefore in a remarkable success.
- a challenging aspect of this process relates to the step of deposition of the products, prior to the strapping.
- a plurality of per se unstable objects as the tiles in a vertical attitude
- the underlying problem of the present invention is therefore to provide an apparatus which overcomes the above drawbacks, i.e. to provide a palletizer for large-format tiles capable to complete the entire operation of deposition and consolidation on pallets, in a fully automatic manner, without the risk for some tile to laterally reverse.
- a palletizer comprises, in a per se known manner, a manipulator (not shown) designed to transfer a plurality of items (such as for example individual large surface tiles or boxes containing some tiles) in sequence to a single or a plurality of deposition stations, wherein the items are arranged in a vertical position (i.e. with the larger surface on the vertical plane) on a pallet.
- a manipulator not shown
- a plurality of items such as for example individual large surface tiles or boxes containing some tiles
- a strapping unit globally indicated with 1, of which in fig. 1 it is shown a quadrilateral frame 2 guiding the strapping, which embraces the plane area 3 of a pallet.
- Each object that is deposited therefore has a variable footprint width from 12 mm (the single tile) to, for example, approximately 48 mm (a box with four tiles), which constitutes a very narrow standing edge on the pallet.
- this edge has a size that - due to the effect of the other dimensions of the box and the weight contained in itself - is not able to ensure the stability needed, that otherwise it is possible to reach only when the footprint width is in the order of 130-150 mm.
- a strapping operation is carried out on the group of items, i.e. a strapping ring is applied - represented by the line 5 in bold in figure 1 - which has the function of tighten together the last deposited item 4a with already existing ones 4b; in this way the group of adjacent items becomes practically a single body that, having globally a much wider footprint, is certainly more stable on the pallet.
- the single item deposited on the pallet is highly unstable and, on the other hand, any further item that is added on the pallet, before initiating any strapping, is still unstable.
- the strapping unit 1 is equipped with a movable pressure member, globally indicated as 10.
- the movable pressing member is integral to the strapping unit, in particular to the guiding frame 2, so as to not interfere either with the pallet displacement, nor with the palletizer movement.
- the pressing member, mounted integral to the strapping unit does not occupy any fixed bulk in the deposition station.
- the presser member is attached to the guiding frame 2, but it is relevant that it is integral in motion with the strapping guiding track, which is that part of the strapping unit that defines the launch and recall path of the strap.
- the pressing member comprises two extendable arms 10 and 10' (one of them is only partially visible in fig. 1 ) laterally arranged by two opposite parts of the pallet area, i.e. so as to face the opposed major surfaces of the tiles laid vertically on the pallet.
- each extendable arm has ( figures 2 and 3 ) a horizontal roller 11, carried at the distal end of a pantograph system 12, whose other proximal end is attached to a supporting frame 13 integral to the guiding frame 2 of the strapping machine.
- the roller with a horizontal axis 11 is preferably mounted to idly rotate.
- the drive assembly 14 On the frame 13 is also arranged a drive assembly 14 that - in a manner known per se and therefore not described in detail - controls the opening and closing of the pantograph system 12, to let it pass from the open working position, shown in fig. 2 , the closed home position, shown in fig. 3 .
- the drive assembly 14 may preferably be of the pneumatic or mechanical type.
- the pantograph When the drive assembly 14 is in the home position, the pantograph is completely closed against the frame 13, as shown in fig. 3 . In this way it does not interfere with the space above the pallet.
- the pantograph 12 is extracted to a sufficient extent to bring the pressing roller 11 in contact with the side of the last of the items 4a present on the pallet.
- the drive assembly is arranged in such a way as to push with a certain force, for example less than 1 kg, the pressing roller 11 against the items, so as to ensure that the last deposited item is maintained against the other.
- each arm there is also provided proximity detection means, such as control photocells 15, that feedback control the drive 14.
- proximity detection means such as control photocells 15, that feedback control the drive 14.
- the first item 4a is deposited on the pallet, holding it with a gripping head of the palletizer.
- the two pantograph systems of the pressing members are closed.
- the two opposing pressing members 10 and 10' are extended, so as to bring the respective rollers 11 in working position against the lateral surfaces of the item, with the stroke of the drive also determined by detecting means 15. Therefore, when the gripping head (not shown) of the palletizer moves away, the first item 4a remains perfectly balanced.
- the second item 4b is brought above the pallet, causing it to descend downwards close to the side of the first item 4a.
- the photocell 15 of the pressing member 10 on the side of the second item 4b detects the insertion of the item and controls the drive 14 to withdraw for a short distance the pantograph system: the retraction of the roller 11 - for a predetermined stroke depending on the thickness of the items - leaves space for the insertion of the second item 4b.
- the step of vertical descent of the gripping head preferably stops at the time in which the added item partially overlaps the previous one of a few centimetres: in a short period of time, the pantograph on the same side wherein the added item is deposited detaches, while on the opposite side, the other pressing member remains in position, so that the product cannot fall.
- the free rotation of the roller 11 cooperates to the downwards slipping of the added item 4b.
- the drive 14 again pushes the roller 11 under pressure against the added item 4b so that it is held against the previous item 4a and cannot overturn laterally.
- a strapping ring 5 is applied consolidating together the two items 4a and 4b. Because - as shown - the launching track 2 of the strap is placed below the pressing members 10 and 10', there is no interference.

Description
- The present invention relates to an enhanced palletizer apparatus, in particular an apparatus designated to consolidate large tiles on a pallet in view of the subsequent packaging and/or use on building sites.
- As is known, a palletizer is an apparatus that serves to stack in an automatic way on a pallet, a series of products for the subsequent packaging. The transfer operation of a plurality of products from a production line to one or more pallets, with an accurate and orderly stacking, can be very tiring and burdensome when carried out manually. In fact, each of the products - in particular, in the context of the present application, boxes each containing a plurality of tiles - must be picked up individually and transferred to one of a plurality of loading pallet, the pallet being chosen (preferably in an automatic way) for example depending on the batch or to the dimensions of the product. Inter alia, so as not to hinder the operations, the various pallet waiting to be loaded are distributed along a line located in an area next to the end of the production line, which implies considerable displacements.
- In the art, there are thus available palletizer equipment, which comprise one or more gripping heads movable on suitable raised guides, suitable to pick up the individual products and transfer them quickly on the pallets to be loaded, arranging the individual products into the appropriate position in the stack on the pallet. Once a certain pallet is fully loaded, the system provides an appropriate signal (acoustic and/or visual) to the operator, who can thus remove the loaded pallet, replacing it with an empty one, and send it on to the next step of packaging (typically performed by heat-shrink or stretch plastic film).
- An very particular application for packaging on pallets can be found in the tile industry. In fact, currently there is an increasing demand for tiles in the form of slabs of very large format, for example 1200x600 and beyond: a stable stacking, with the larger surface lying horizontally, would easily cause breakage of these tiles (due to their flexibility and under the weight of the stack).
- It was therefore already proposed to stack the tiles with their major surfaces placed vertically, i.e. by resting them on the pallet with their larger edge. To this end,
IT1408944 - A challenging aspect of this process, relates to the step of deposition of the products, prior to the strapping. In fact, when there is a need to place on the pallet a plurality of per se unstable objects (as the tiles in a vertical attitude), because equipped with a very small footprint with respect to their total volume, it arises the need to keep them balanced as long as they have not been consolidated to a body with a wider and more stable support. Let's consider, for example, that a box typically containing three tiles having dimensions of 600 x 1200 mm and a thickness of 12 mm, will have a standing edge 36 mm wide, which certainly makes it susceptible to a reversal. The problem is even worse when supposing to place the single tiles on the pallet.
- In
IT1408944 - In the field of automatic industrial systems, there are several devices that utilize pushing and pressing mechanisms suitable to act on the products in formation, e.g. see
US2015/175283 . However these known members are intended to apply a slight pressure on the products, for example to guide them in their movement or to keep away some parts during processing. Therefore they are not applicable in palletizing stations of large tiles, because they would be ineffective to support the heavy tiles, or excessively bulky and expensive if repeated on the various stations of a palletizer. - The underlying problem of the present invention is therefore to provide an apparatus which overcomes the above drawbacks, i.e. to provide a palletizer for large-format tiles capable to complete the entire operation of deposition and consolidation on pallets, in a fully automatic manner, without the risk for some tile to laterally reverse.
- This objects are achieved by the features mentioned in the main appended claim. The dependent claims describe preferred features of the present invention.
- Further features and advantages of the invention will anyhow become more evident from the following detailed description, given by mere way of non-limiting example and illustrated in the accompanying drawings, wherein:
-
Figure 1 is a schematic, perspective view of an embodiment of the invention; -
Figure 2 is a schematic, perspective view of an exemplary embodiment of a pressing member, in working position; and -
Figure 3 is a similar view to that offig. 2 , with pressing member in resting position. - A palletizer comprises, in a per se known manner, a manipulator (not shown) designed to transfer a plurality of items (such as for example individual large surface tiles or boxes containing some tiles) in sequence to a single or a plurality of deposition stations, wherein the items are arranged in a vertical position (i.e. with the larger surface on the vertical plane) on a pallet.
- According to the teaching of
IT 1408944 fig. 1 it is shown aquadrilateral frame 2 guiding the strapping, which embraces theplane area 3 of a pallet. - On the pallet it is provided that a plurality of tiles or of the
respective boxes - Each object that is deposited, therefore has a variable footprint width from 12 mm (the single tile) to, for example, approximately 48 mm (a box with four tiles), which constitutes a very narrow standing edge on the pallet. As it can easily understood, this edge has a size that - due to the effect of the other dimensions of the box and the weight contained in itself - is not able to ensure the stability needed, that otherwise it is possible to reach only when the footprint width is in the order of 130-150 mm. There is therefore the need to artificially keep individual items balanced, at least in the initial phase of deposition, but also subsequently as other items are added.
- According to the packaging procedure, known per se, other than the first item that is alone on the pallet, after each following item which is brought up to the previous one, a strapping operation is carried out on the group of items, i.e. a strapping ring is applied - represented by the
line 5 in bold infigure 1 - which has the function of tighten together the last depositeditem 4a with already existingones 4b; in this way the group of adjacent items becomes practically a single body that, having globally a much wider footprint, is certainly more stable on the pallet. - At least in the initial step of loading of the pallet, the single item deposited on the pallet is highly unstable and, on the other hand, any further item that is added on the pallet, before initiating any strapping, is still unstable.
- According to the present invention, to ensure the stability of the load on the pallet throughout the step of deposition on the pallet, it is provided that the strapping
unit 1 is equipped with a movable pressure member, globally indicated as 10. The movable pressing member is integral to the strapping unit, in particular to the guidingframe 2, so as to not interfere either with the pallet displacement, nor with the palletizer movement. The pressing member, mounted integral to the strapping unit, does not occupy any fixed bulk in the deposition station. For the purposes of the invention, it is not so essential that the presser member is attached to the guidingframe 2, but it is relevant that it is integral in motion with the strapping guiding track, which is that part of the strapping unit that defines the launch and recall path of the strap. - According to a preferred embodiment, the pressing member comprises two
extendable arms 10 and 10' (one of them is only partially visible infig. 1 ) laterally arranged by two opposite parts of the pallet area, i.e. so as to face the opposed major surfaces of the tiles laid vertically on the pallet. - In particular, each extendable arm has (
figures 2 and 3 ) ahorizontal roller 11, carried at the distal end of apantograph system 12, whose other proximal end is attached to a supportingframe 13 integral to the guidingframe 2 of the strapping machine. The roller with ahorizontal axis 11 is preferably mounted to idly rotate. - On the
frame 13 is also arranged adrive assembly 14 that - in a manner known per se and therefore not described in detail - controls the opening and closing of thepantograph system 12, to let it pass from the open working position, shown infig. 2 , the closed home position, shown infig. 3 . Thedrive assembly 14 may preferably be of the pneumatic or mechanical type. - When the
drive assembly 14 is in the home position, the pantograph is completely closed against theframe 13, as shown infig. 3 . In this way it does not interfere with the space above the pallet. - When the
drive assembly 14 is located in the working position, thepantograph 12 is extracted to a sufficient extent to bring thepressing roller 11 in contact with the side of the last of theitems 4a present on the pallet. The drive assembly is arranged in such a way as to push with a certain force, for example less than 1 kg, thepressing roller 11 against the items, so as to ensure that the last deposited item is maintained against the other. - The same type of action occurs with the two
opposing arms 10 and 10', therefore even a single item can be maintained stably upright between the two opposite pressing actions acting on the two opposite faces of the item. - At the distal end of each arm there is also provided proximity detection means, such as
control photocells 15, that feedback control thedrive 14. With this construction it is possible to detect when an item is approaching the distal end of the pantograph arm from the top, so as to produce a slight backward movement of theroller 11 and to allow the introduction of a new item between the ones already deposited and thepressing roller 11. - The operation of the palletizer according to the invention is as follows.
- At beginning, the
first item 4a is deposited on the pallet, holding it with a gripping head of the palletizer. The two pantograph systems of the pressing members are closed. - Before releasing the grip, the two opposing pressing
members 10 and 10' are extended, so as to bring therespective rollers 11 in working position against the lateral surfaces of the item, with the stroke of the drive also determined by detectingmeans 15. Therefore, when the gripping head (not shown) of the palletizer moves away, thefirst item 4a remains perfectly balanced. - After that, the
second item 4b is brought above the pallet, causing it to descend downwards close to the side of thefirst item 4a. - During the descent, the
photocell 15 of the pressingmember 10 on the side of thesecond item 4b, detects the insertion of the item and controls thedrive 14 to withdraw for a short distance the pantograph system: the retraction of the roller 11 - for a predetermined stroke depending on the thickness of the items - leaves space for the insertion of thesecond item 4b. The step of vertical descent of the gripping head preferably stops at the time in which the added item partially overlaps the previous one of a few centimetres: in a short period of time, the pantograph on the same side wherein the added item is deposited detaches, while on the opposite side, the other pressing member remains in position, so that the product cannot fall. Also the free rotation of theroller 11 cooperates to the downwards slipping of the addeditem 4b. Before the gripping head moves away again, thedrive 14 again pushes theroller 11 under pressure against the addeditem 4b so that it is held against theprevious item 4a and cannot overturn laterally. - In this condition, while the gripping head starts a new gripping cycle, a strapping
ring 5 is applied consolidating together the twoitems launching track 2 of the strap is placed below thepressing members 10 and 10', there is no interference. - Said operation is repeated as long as items tied each other generally have not a supporting base wide enough (for example with a width of 150 mm) as to be able to remain autonomously stable. Thereafter the pressing members can also be disabled if the strapping of the new items is performed while the gripping head is still engaged on the pallet; vice versa, if reasons of working cycle optimization suggest to rapidly release the gripping head, it is possible to continue to use the pressing members for all the subsequent items that have to be deposited on the pallet.
- To accommodate various items on the pallet it is possible to proceed alternatively or in sequence. To proceed alternatively, action is alternated on the opposite pressing
members 10 and 10', supporting an item after another alternately on one side and the other of the preceding items (which are necessarily positioned starting from the centre of the pallet, as shown infig. 1 ). To proceed in sequence, the operation is applied always from only one side of thefirst item 4a, arranging the additional items always alon said side: in this case the first item must be positioned in proximity of one of the edges of the pallet. - According to an alternative embodiment, the palletizer is provided with only one pressing member on one of the sides of the strapping unit. In this case a contrast element integral to the pallet can be provided, apt to define an abutment support for the side of items which is opposite to the pressing member. The contrast element is preferably a rib or wall that projects perpendicularly to the plane of the pallet, arranged on one side (thereby forming a pallet with L shaped vertical section) or centreline (thus forming a pallet with reversed T shaped vertical section). The contrast element can be made of the same material as the pallet (typically made of wood or plastic), or may be manufactured separately from other materials.
- As can be seen from the above description, the device according to the invention perfectly solves the objects set forth in the premise. The pressing members are integral to the strapping track and allows to stabilize the load while waiting for the strapping to be completed and, at the same time, do not interfere with any member intended to complete the palletizing process, nor causing an unwanted bulk in the area of the loading station.
- It is understood, in any case, that the invention is not to be considered as limited by the particular embodiment illustrated above, which represent only one possible exemplary embodiment of the same, but different variants are possible, all within the reach of a person skilled in the art, without departing from the scope of the invention itself, as defined by the following claims.
- In particular, although it has always been described a pressing member in the form of a roller carried by a pantograph system, it is not excluded to be possible to use any other pressing member, also constructively simpler than a pantograph.
- Further, the pressing members were shown opposite at the two lateral parts of the items, but it is not ruled out that the pressing arms can be installed on a front end area of the items, for example in proximity of the strapping head. In this way, the arms would be mounted in rotation (with vertical axis) on a rotating system, so they can be opened and closed on the load with a swinging movement on the horizontal layer. In this variant, the lateral stroke of the pressing members would not be limited by the need to attach them to the structure of the guiding track 2: mounting in rotation would result in fact in spacing them apart each other to the point of bringing them completely outside of the area of the side projection of the items. The advantage of this configuration lies in the fact that an accidental overturning of the items - obviously on their side - cannot cause significant damage to the pressing arms, that would simply be pushed away from their operating position.
- Furthermore, the
end roller 11 can be replaced by any other element that represents an effective guide for the item coming from above so as to prevent jam operation: for example a flare connected flap, of self-lubricating material (Teflon type), can perform an equivalent function. The same means for proximity detection could take the shape of a feeler instead of a photocell.
