Definitions
- the present invention is in the field of conveying objects. It relates more particularly to an object transfer device.
- a packaging line generally includes a blower-filler-labeller, a shrinkwrapper and a palletizer.
- the objects, to be moved from one machine to another, are usually transferred to single-wire or multi-wire conveyors.
- Accumulation tables can be arranged on the processing line to manage the flow of objects.
- Such a type of transfer has significant disadvantages, such as the high risk of falling objects and jamming at high rates.
- the whole line must be stopped.
- each line can only work to produce pallets with identical and uniform layers, composed of uniform packs.
- WO201 1 131704 proposes a transfer device comprising a closed loop, on which move carts for transferring between two machines, the carriage being actuated by a linear motor.
- the system is not flexible, and the unavailability of one of the machines blocks the entire processing line.
- the present invention aims to overcome at least in part these disadvantages by providing a flexible system for individual transfer of each object, allowing a transfer of objects from one line to another.
- a device for transferring objects of an installation comprising at least two lines each comprising an upstream machine of the blower-filler-labeller type, an intermediate machine in the form of a shrinkwrapper or packager, and a palletizer downstream.
- Said transfer device is particular in that it comprises for each line at least one linear stator, a plurality of carriages, each provided with means for holding at least one object, and each secured to a rotor configured to moving along one of said linear stators according to the principle of a linear motor, and in that it comprises at least one switch, configured to allow a choice between a transfer limited to the same line, and a transfer with change line. Thanks to these provisions, it is possible to transfer objects from one line to another, for example in the event of a prolonged stoppage of a machine or to meet particular needs, such as the realization of packs composed of objects.
- the movement of the objects between the different machines of the line can be controlled individually, the switching commands can be realized in a centralized manner for example by loops or by lines, and adjusted in real time at high speeds without risk of falls , stuffing and jamming objects.
- said holding means may be disposed above or below said rotor, so as to enable said rotor to be guided by one or both of two opposite lateral sides, the rotor thus being guided by two different stators in the same horizontal plane, and simultaneously, especially at the point of a switch,
- said switch may be magnetically controlled, said rotor being guided on a lateral side by a first stator, and by its opposite lateral side by a deflection stator, the switch thus requires no room displacement, and may be automated to individually process each rotor, and a centralized control can handle all the switches of the device,
- each line may comprise, on the one hand, between the upstream machine and the intermediate machine and, on the other hand, between the latter and the downstream palletizer, two stators in a closed circuit in a horizontal plane, arranged in alignment with each other; the other, this constituting a simple means of carrying out the invention, and making it possible to manage the mixing zones between empty trolleys and loaded trolleys,
- said device can comprise
- At least one stator connecting by switches o firstly the first closed circuit stator of the first line to that of the second line so as to allow the carriage of the carriages from the first line to the second line, and o secondly the second closed circuit stator from the first line to the second line so that cars can move from the second line to the first line, allowing transfers between two successive machines from any line to any other line ,
- the said switch may be mechanically controlled, comprising a mechanical transfer device for guiding a first stator (5) to a deflecting stator, this constituting an inexpensive and robust means of carrying out the invention.
- the present invention also relates to a method of transferring objects in an installation comprising at least two lines each comprising an upstream type blower-filler-labeller machine, an intermediate machine in the form of a shrinkwrapper or packager, and a palletizer in downstream, characterized in that it is implemented by a device according to one of the preceding claims.
- said device may comprise at least two lines, an intermediate machine being stationary on a line, and the objects being distributed towards the other intermediate machines, then a similar number of objects being brought back to the palletizer of said line, as well as the upstream machine and the palletizer of the line on which the intermediate machine is stationary may continue to operate,
- the upstream machine of the first line can produce objects different from the one of the second line, and some of the objects of the first line are transferred before the palletizer to the second line, and some of the objects of the second line are transferred before the palletizer to the first line, so as to allow the palletizer to produce pallets with layers of different objects, this type of pallet being useful for example to deliver drinking places with little storage space,
- the machine upstream of the first line can produce objects different from the one of the second line, and some of the objects of the first line to be transferred before the intermediate machine to the second line, and some of the objects of the second line to be transferred before the palletizer to the first line, so that the shrinkwrapper or packager can produce packs of at least two separate objects, for example to insert a promotional object in a pack of conventional objects, or to realize packs containing a bottle of syrup and 5 bottles of water, or making packs with different juices as long as the bottle sizes are consistent.
- FIG. 1 is a schematic view of a device according to the invention
- FIG. 2 is a view of a detail of FIG. 1.
- FIG. 3 is a sectional view of an object being transported by a rotor according to the invention.
- the transfer device comprises at least two object processing lines 1.
- Each line comprises an upstream machine 2, which can be a blower-filler-labeller, a machine intermediate 3, which is a shrinkwrapper or a packager, and a palletizer 4 downstream, and a flow of products is preferably installed in this line during normal operation.
- An object may for example consist of a bottle or a brick of fruit juice or milk that leaves the machine upstream. These objects are then fardelés or cashed on the intermediate machine 3, and we obtain packs or crates, which are then transferred as a single entity to the palletizer. Such packs or boxes will also be considered as objects within the scope of the present invention, objects which are then transferred individually to the palletizer 4 downstream.
- the device also comprises for each line at least one linear stator, on which rotors 6 move according to the principle of a linear motor. As illustrated in fig. 3, on each rotor 6 is fixed a carriage 7, provided with a holding means 8 of an object 1.
- the objects 1, in the form of bottle or individual brick on the one hand, or in the form of packs produced by the shrinkwrappers, or crates produced by the case packers on the other hand, can therefore be transferred individually along the stators 5, via the rotors 6 controlled in a centralized manner.
- the holding means 8 being individual for each object 1, such as a tray or clamp gripping a container by its neck, the risk of falling objects 1 is very small, and the usual jamming or jamming when using conveyors is removed.
- the device finally comprises at least one switch 9.
- the switch 9 can be configured either to leave the objects 1 on the same line, or to transfer the objects 1 to another line.
- the holding means 8 is disposed above or below the rotor 6.
- the rotor 6 can be guided by one of its lateral sides, cooperating with the stator 5. This allows for example to achieve a switch 9 to magnetic control, the implementation can take place, as shown in FIG. 2, according to the following steps:
- the rotor 6, at the approach of the switch 9, moves along an upstream stator 5 via the contact of one of its lateral sides with the upstream stator 5,
- the rotor 6 comes into magnetic contact with a deflecting stator 5 ', via its opposite lateral side,
- the switch 9 with magnetic control makes it possible to switch each rotor 6 individually, and thus provides a very great flexibility to the device according to the invention. For example, it is possible to transfer one out of every two objects to the deflection stator 5 'and to leave one object out of two on its original stator, or any other type of distribution required.
- the switch 9 may be mechanically controlled.
- the switch 9 then comprises a mechanical transfer device for guiding a first stator (5) to a deflection stator.
- This embodiment has the disadvantage that it requires moving parts to actuate the switch 9.
- each line of the device according to the invention comprises, on the one hand, between the upstream machine 2 and the intermediate machine 3 and, on the other hand, between the intermediate machine 3 and the palletizer 4 downstream, two stators 5 in a closed circuit in a horizontal plane.
- These two stators 5 can be arranged in alignment with one another and connected by switches 9.
- the objects 1 to be transferred between two successive machines 2, 3, 4 of the same line pass over the two stators 5 It can then be provided, as illustrated in FIG.
- an object 1 from an upstream machine 2 it is then possible, for an object 1 from an upstream machine 2, to continue on the same line and to be processed by the intermediate machine 3 of the same line, or to change lines and to be processed by the machine. intermediate machine 3 from any other line. Similarly for an object 1 from an intermediate machine 3, and which can be transferred to the palletizer 4 of any line.
- FIG. 1 allows that when on a given line, only one of the machines 2, 3, 4 is stopped, the objects 1 present upstream on the same line can be transferred to another line, or distributed over several other lines if the device has at least three lines. However, this transfer method can also work with at least two lines.
- the objects 1 can then be processed by the corresponding machine 2, 3, 4 of another line.
- the rotors 6 being individually controlled in a centralized manner, the distribution of the objects 1 to other lines is flexible: it can be done according to the level of load that the other lines already support, and can be reconfigured in real time. Once objects 1 processed by the corresponding machine 2, 3 of another line, they can be retransferred or not to their original line for the next machine 3, 4.
- the objects 1 from the upstream machine 2 of the second line can be distributed to the wrappers 3 of the first and the third line, or a fourth or fifth line, then redirected out of wrapping machine 3 to the palletizer 4 of the second line.
- the centralized individual control of the carriages 7 makes it possible, when restarting a machine 2, 3, 4, to send a reduced flow of objects 1 for test the machine 2, 3, 4, then gradually increase the load to the normal production rate.
- the palletizer 4 of the first line is stopped, it is possible to imagine that the objects 1 at the end of the shrinkwrapper 3 of the first line are transferred to the palletizers 4 of the second and third lines, or even more lines.
- the restart of the palletizer 4 of the first line we can continue to send most of the objects 1 to the palletizers 4 of the second and third lines so that the palletizer 4 of the first line resumes at a low rate, before gradually increasing the rate of the palletizer 4 of the first line until there is no longer need to transfer the objects 1 to the palletizers of the second and third lines.
- Another advantage of the present invention is that in case of installation of an additional line in the device, each machine can start independently of the other machines of the line and particularly of the machine which precedes, which allows a much more flexible the new line, and easier to organize.
- the device according to the embodiment of FIG. 1 can also be used to produce pallets whose layers each comprise at least two different objects 1, for example according to the following method:
- the upstream machine 2 of the first line produces objects A, that of the second line of objects B, and that of the third line of objects C.
- pallets By partially transferring the object packs of each line to the palletizers of the other lines, pallets can be obtained, one layer of which is composed of packs of objects A, the next layer of packs of objects B and the next layer of C object packs You can also get different packs of objects in the same layer or palette.
- the wrappers 3 of the different lines can also produce packs of objects 1 of different formats.
- the wrappers 3 of the different lines can also produce packs of objects 1 of different formats.
- the shrinkwrapper 3 of the first line produces packs of 6 bottles, that of the second line packs of 12 and that of the third line packs of 24.
- By judiciously distributing the packs to the palletizers 4 thanks to the individual control of the movement of each pack, it is possible to produce pallets alternately comprising a layer of packs of 6 objects 1, a layer of packs of 12 objects 1 and a layer of packs of 24 objects 1.
- Such multi-format pallets can be particularly useful for supplying intermediate stocks, from which the adapted packs can leave for each final destination.
- such multi-format pallets make it possible to avoid repackaging, that is to say that the pallet no longer has to go through an intermediate packaging company, the pallet is ready directly for the final seller.
- the device can finally be used to make packs with different products.
- the method for arriving at different product packs includes a step of transferring objects 1 of different types from different lines to a bundling machine or a common packager. It is thus possible to produce packs comprising a promotional product, for example according to the following method implementing a device comprising five lines:
- the upstream machine 2 of the first line produces objects Xi, that of the second line of objects X 2 , that of the fourth line of objects X 3 , that of the fifth line of objects X4, while that of the third line produces promotional Y objects.
- Y objects at the output of the upstream machine 2 are partially distributed to the wrappers 3 of the other lines.
- the individual control of the displacement of each object 1 makes it possible, for example, for each shrinkwrapper to receive 5 objects X1 of the first line and then an object Y of the third line. - Some Y objects remain on the third line and are processed by the third-line shrinkwrapper 3 to produce complete packs of Y-products.
- the wrapper 3 of the first line then produces packs of six objects 1, consisting of five objects Xi and a Y object. This is similar in the second, fourth and fifth lines.
- each line comprises, on the one hand, between the upstream machine 2 and the intermediate machine 3 and, on the other hand, between the latter and the downstream palletizer 4, two closed-circuit stators 5 in one horizontal plane, arranged in alignment with each other.
- two stators 5 that follow can include:
- switches 9 are arranged at the crossings between the two stators 5 to be able to go from the first stator 5 to the second and vice versa.
