Description

PACKAGING MACHINE FOR VACUUM PRODUCTS
The present invention refers to a packaging machine for vacuum products.
As known, the art proposes machines and equipment for packaging products inside a vessel and vacuum sealed: in fact, by removing air, and consequently also oxygen, from the vessel in which the products are laid, vacuum is created and by hermetically sealing said vessel, the product benefits from a storage thereof in time.
For such purpose, the techniques of making' the above machines can be different and several. In fact, they can be both of the manual and of the automatic type. Similarly, the product vessel can be different: in fact, it can be composed of a simple bag made of plastic material where the product to be put under vacuum is inserted, as well as a real vessel made of suitable solid material, resistant to vacuum depression that is formed inside it.
The same both manual and automatic machines can insert in the vessel (after having removed air through vacuum) a specific gas for storing foodstuffs .
These vacuum-forming machines are mainly made of stainless steel in order to resist to material oxidation and the structural stresses deriving from the presence of vacuum inside them, in addition to guarantee the maximum hygiene for foodstuffs. In fact, they must guarantee the chance of being cleaned in all their parts in contact with the product, realising smooth and rounded surfaces. Normally these machines are composed of a tank with suitable sizes, where the product in its vessel is inserted. In this tank there are also the devices adapted for welding and sealing the vessel (in this case the open bag part containing the product under vacuum) . By then closing the tank cover, vacuum is automatically generated inside it, and then consequently also inside the bag containing the product. Automatically, after having reached the desired vacuum, the welding bars rise on the open bag part against an abutment, and they take care of sealing the product under vacuum inside the bag. Afterwards, opening of a suitable valve introduces external air in the tank, freeing the tank closing cover held by vacuum. The operator can then extract the bag with the product put under vacuum.
Other known vacuum packaging systems are composed of automatic machines that work products put on a line. These automatic machines contain a complex mechanical technology and need a frequent and specialist preventive maintenance.
Other manual machines, with a simpler arrangement, are given by systems operating with product-bearing planes and oscillating vacuum domes. In particular, these machines are used for packaging usually bulky and heavy products.
Object of the present invention is solving the above prior art problems by providing a packaging machine for vacuum products that is simpler and more rational under practical and functional points of view with respect to what is proposed by the known prior art.
Another object of the present invention is providing a packaging machine for vacuum products exclusively made of plastic material, resulting practical for the washing operation of parts in contact with the product.
Moreover, an object of the present invention is providing a packaging machine for vacuum products in which the product to be packaged is visible during its whole operating packaging cycle.
Another object of the present invention is providing a packaging machine for vacuum products with reduced overall sizes and low energy consumption .
Another object of the present invention is providing a packaging machine for vacuum products with modular configuration, since it can possibly be equipped with a module adapted to be assembled and suitable for forming small bags of plastic material for vacuum packaging.
The above and other objects and advantages of the invention, as will result from the following description, are obtained with a packaging machine for vacuum products as claimed in claim 1. Preferred embodiments and non trivial variations of the present invention are the subject matter of the dependent claims.
It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) can be made to what is described, without departing from the scope of the invention as appears from the enclosed claims. The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:
FIG. 1 shows a top perspective view of a preferred embodiment of the packaging machine according to the present invention;
FIG. 2 shows a front view of the packaging machine of FIG. 1;
FIG. 3 shows a side view of the packaging machine of FIG. 1 and 2;
FIG. 4 shows the packaging machine of FIG. 3 without a side bulkhead;
FIG. 5 shows the packaging machine of the previous Figures equipped with a module for forming small bags made of plastic material;
FIG. 6 shows a front view of the packaging machine of FIG. 5;
FIG. 7 shows a sectional view of the packaging machine of FIG. 6 along section line A-A;
FIG. 8 shows a plan view of the packaging machine of FIG. 5; and
FIG. 9 shows an enlarged view of the part contained in window B of FIG. 6.
With reference to the Figures, it is possible to note that the packaging machine 1 for vacuum products 31 according to the present invention comprises a base plane 3 made of plastic material on which at least one oscillating dome 5 and its related actuating device 7 are inserted: in particular, the actuating device 7 of the dome can be of the torsion bar type or with extendible springs. On the same base plane 3, the packaging machine 1 further comprises at least one welding bar 9, possibly at least one delivering nozzle 11 for a gas, at least one air inlet mouth 13, possibly at least one switching-on unit composed of a feeler 15b, preferably integral with the dome 5 and a corresponding micro-switch 15a arranged on the base plane 3 and possibly at least one control keyboard 17. Depending on specific needs, the welding bar 9 can be both linear and angular. Possibly, the packaging machine 1 could comprise at least one welding machine for envelopes.
In particular, the packaging machine 1 can also comprise a double dome (not shown) with separate or synchronous descent. In particular, the dome 5 can be made of steel or transparent plastic material .
Below the base plane 3 a room can be obtained, circumscribed by a protecting fairing 19 inside which there are the necessary devices for operating the packaging machine 1 according to the present invention: in particular, with reference to FIG. 4 that shows the machine 1 lacking a bulkhead of the protecting fairing 19, it can be noted that the above devices comprise at least one pump 21 for generating vacuum inside the dome 5, at least one connection duct 25 with the air inlet mouth 13 and related filter, a membrane assembly 27 for lifting the welding bar 9, at least one control solenoid valve 23 of the membrane assembly 27 and obviously a transformer for the welding bar 29.
As described above, a possible operating process, either automatic or manual, of the packaging machine 1 according to the present invention is the following:
- a product 31 to be packaged is placed (FIG. 3 and 4) inside a bag 33 made of a plastic film on the base plane 3 with the upper open edge arranged on the welding bar 17; possibly, the edge of the bag 33 can also be arranged around the delivering nozzle 11;
- the dome 5 is then lowered, by possibly operating on a handle 5a of this latter one, till it is taken against the base plane 3;
- if present, the feeler 15b then actuates the micro-switch 15a that operates the pump 21 which, through a suitable circuit, produces vacuum inside the dome 5; alternatively, the pump 21 could be manually actuated by an operator once having closed the dome 5. Possibly a specific gas for storing the product 31 can be introduced inside the bag 33 through the delivering nozzle 11;
- after having reached the desired vacuum level, possibly set by a control card, the membrane assembly 27 automatically starts operating through the solenoid valve 23 that, by lifting the welding bar 9, is automatically heated through pulses, or, by closing the edges of the bag 33 against a corresponding abutment 35 arranged inside the dome 5, the edges of the bag 33 are welded in a vacuum environment; also in this case, the membrane assembly 27 could be manually actuated by an operator;
- after having ended the welding, outside air is manually or automatically inserted inside the dome 5 through the air inlet mouth 13: the dome 5 will then be opened to allow extracting the bag 33 with the product 31 arranged under vacuum. Possibly, it can be provided to introduce, through known means, hot air inside the dome 5 in order to thermoform the bag 33.
As previously described, the packaging machine 1 according to the present invention is inexpensive and practical both for the production cycle, and for cleaning the machine that gets in contact with foodstuffs. Since in particular the part subjected to vacuum is very small (only the internal volume of the dome 5) , the machine is very quick in performing its own operating packaging cycle.
In particular, the packaging machine 1 according to the present invention can be manufactured both in a version for bench and can be equipped with a suitable support stand 37 that can be moved with adequate wheels, such stand 37 being for example the support structure disclosed in Utility Model Patent Application n. IT-A-TO2005U132 of the same Applicant.
Advantageously, the packaging machine 1 according to the present invention can also have a modular configuration, and then be equipped with at least one module 40 adapted for forming small bags 33 made of plastic material for vacuum packaging the product 31. With reference in particular to FIG. 5 to 8, it is possible to note that the module 40 is composed of a working plane 41 on which at least one pulse-type welding machine 43 is placed, equipped with due welding bands and a hot cutting blade or a small, manually or automatically translating knife for cutting a plastic film 44 arranged in the centre of the two welding bands.
The single-bend plastic film 44, preferably wound on coils 45 with different sizes at choice, is taken under the pulse-type welding machine 43 and, after having operated with the first spot welding, the film is moved, aligning it with at least one cursor 47 that points out ' the desired size of the bag 33.
By lowering the pulse-type welding machine 43 possibly through a handle 43a down to at least one corresponding abutment 43b placed on the working plane 41, at least one micro-switch 48 is automatically actuated and in turn activates the pulse-type welding machine 43 that welds the film 44 closed between the welding machine 43 and the below abutment 43b. In this way, a bag 33 of the plastic film 44 will be obtained with three closed sides and one open side for inserting the product 31 to be afterwards placed under vacuum through the packaging machine 1.
The welding machine 43 can also be manually oscillating or fixed and parallel to the working plane 41 with a closing movement of the vertical pedal type or with sucking electromagnets or with possible other mechanical systems.
The module 40 could also be equipped with means adapted to perform a double welding and an engraving by cutting on the film 44.
The control keyboard 17 of the packaging machine 1 can be connected to the module 40 through a suitable electric circuit 49.
Obviously, similarly to what has been arranged for the packaging machine 1 to which it must be able to be coupled, also the module 40 can be made both for a bench and equipped with a support trolley 51 with two or more legs and equipped with wheels; in a preferred embodiment thereof, the support trolley 51 has one or more coils 45 of single-bent plastic film 44 with different widths arranged by the operator according to various operating needs.
Moreover, the module 40 can' be equipped with coupling means 53 to the packaging machine 1 in order to make it integral with this latter one: preferably, such coupling means, as shown for example in FIG. 6 and 9, can be made as at least one first "U"-shaped profile 53a integral with the packaging machine 1 inside which a leg of at least one second inverted "U"-shape profile 53b, integral with the module 40, can be inserted. Obviously, the working base plane 3 can be both planar and of the embedded type.
As clearly appears from what has been previously described, the chance of providing the packaging machine 1 with at least one module 40 adapted for forming the small bags 33 is extremely advantageous both for the operator, that can form small bags 33 of the desired sizes, and as regards the consequent savings of expenses for such bags that otherwise would have to be purchased as already formed.
