Description
- This invention concerns improvements to an apparatus for creating a vacuum in containers, both flexible like bags, and rigid like jars or canisters, designed to preserve vacuum-packed products.
- To create a vacuum in containers in general and for the abovementioned use, an apparatus, among others, is already available that basically comprises a base plate defining at least a part of a suction chamber, and a casing or overhanging cover, that defines a remaining part of said suction chamber and that is provided with
- a vacuum pump,
- a sealing bar, and also
- control and management devices of the various functions of the apparatus.
- The upper casing or cover is associated with the base plate and is moveable by rotating it above the latter between an opening and closing positions of the suction chamber whereas the lower plate, if required, can be completely removed so as to be washed separately from the casing or cover, consequently without involving the vacuum pump or even more important the electric or electronic components that always remain closed and protected in the casing or cover.
- Such an apparatus, agreed that its overall configuration with the vacuum pump, sealing bar and control and management apparatus of the various functions present in the upper casing or cover, was however found to be susceptible to improvements to increase its performance plus its functionality and practicality.
- On the other hand the documents U.S.20051050856; DE 34 03534; EP 1990 280; EP 1564 14 8 appear to be indicative of the present state of the technique.
- It is therefore an objective of this invention to provide a apparatus that meets the abovementioned type for the formation of a vacuum, at least in flexible containers such as bags, incorporating a decomposable flat base, an original closing and releasing blocking device between the base plate and upper casing or cover, a roll carrier space on the base plate and a cutter associated with the casing or cover and which can move towards the flat base.
- This objective is achieved, according to the invention with an apparatus for the formation of the vacuum in bags or canister according to at least claim 1.
- In this way, the base plate instead of being completely separable from the casing or cover, can comprise only a removable and washable part, in particular a part defining a basin to collect the fluids or substances that may flow out of the container during the suction phase to create a vacuum.
- Furthermore, for its operation, the blocking and releasing apparatus can be provided with one or more maneuvering levers or knobs which can be used individually or both at the same time, so that the closing of the apparatus to be used and then opening it after being used can both be carried out either using only one hand or using two. In addition, the block and release devices can be associated with means for the control of other functions, such as the control of a micro switch provided to enable the functioning of the device only after it has been trimmed and blocked on closing and, where required, the command of an air valve so as to close it when the equipment is in use and to immediately open it before the equipment is opened following use.
- The invention will however be described in greater detail in the following making reference to the attached explicative drawings, in which:

FIGS. 10 , 11 and 12 show a detail of the control system of the air valve in the open, intermediate and closed positions respectively, according to the section line B-B inFIGS. 5 and 6 ; -
FIG. 13 shows a view of the apparatus open in an extraction and cutting phase of a length of tubular element; -
FIG. 14 shows a view of the apparatus in which the base plate is completely separated from the upper casing or cover; -
FIG. 15 shows a version of the apparatus in which the base plate has only one removable portion; -
FIGS. 16 and 17 show in sequence the separable part in the extraction phase and totally removed from the flat base: and -
FIG. 18 shows an enlarged detail of the sealing bar and the respective packing. - The apparatus represented comprises a
base plate 11 to which is coupled anupper casing 12, or cover, rotating between a raised opening position above the base plate and a lowered closed position, that is to say operative, in which the upper casing or cover, becomes blocked on the base plate by means of aclamping device 13 which will be described further on. - According to an embodiment, the
base plate 11 and the casing orcover 12 are connected to each other, but separable one from the other, as shown inFIG. 14 , to enable the manipulation and the washing of the first independently from the second. - The
base plate 11 carries on its upper face, adjacently to its front side, a profiledcontrary gasket 14 and parallel, behind the latter, it has anoblong slot 15, possibly enclosed by aseal 16 facing upwards. Basically, theslot 15 can act as a receptacle for collecting possible fluid substances that can be sucked and exit from a container during the formation of the vacuum. However, in theslot 15 there could be provided, even though not shown, a tank for collecting fluid substances. This tank will preferably be removable so as to be cleaned and provided, or not, with a rod to hold the mouth of a flexible container in position. - In the casing or
cover 12 are positioned—FIGS. 5 and 6—a vacuum pump P, a pressure switch T, at least one solenoid valve EV and all the functional components, pneumatic and electric commands and controls of the various work phases of the apparatus. Furthermore, these components could be integrated that is to say pre-assembled on a support panel to facilitate the realization of the machine. On an upper wall of said casing or cover 12 aninstrument board 17 is provided with instruments and pushbuttons which enable the user to manage the machine and its functions according to requirements. - The casing or
cover 12 delimits, in a part of its lower face, anaspiration chamber 18 that, for example, is connected by means of amulti-way block 118—FIGS. 10-12—to the vacuum pump P according to the F arrow, to a pressure switch T according to arrow G and to a breather pipe S according to the H arrow. Thesuction chamber 18 is in turn, surrounded by aseal 19 which faces towards and coincides with theseal 16 placed either around theslot 15 or, where envisaged, the tank on thebase plate 11. Furthermore, on the front of thesuction chamber 18, the casing orcover 12 holds asealing bar 20 which, when the machine is closed, coincides with a profiledcontrary gasket 14 on thebase plate 11. Preferably, thesealing bar 20 rests on flexible means, forexample leaf springs 120—FIG. 18—operating to push said sealing bar towards thecontrary gasket 14 supported by thebase plate 11. This layout enables the sealing operation to be carried out more easily even in the lack of suction on the part of the pump that is to say that the vacuum pump not operating. In fact the thrust of the flexible means 120 on the sealing bar permits, in all cases, to maintain the two opposite faces near each other so that they can be sealed. - Between the
base plate 11 and the upper casing, a space designed to house aroll 22 of a tubular element is provided in addition and is gradually extractable from the front of the apparatus which from time to time cuts alength 22′—FIG. 13—for the preparation of a bag at the required length at the time of packaging the products that need to be preserved. As shown—FIG. 4—this space is delimited by anotch 21 on the back of itsslot 15, or tank, together with aroll cover element 21′, which is reclining, and is mounted inside theupper casing 12. On the other hand, acutter 23 is associated with the upper casing orcover 12, which in the example illustrated has a frame associated with theabovementioned roll cover 21′ and in the illustrated example has a frame associated with the abovementionedroll cover element 21′ and is a turn-up with the latter. Practically, with the apparatus open the cutter moves into a vertical idle position, accosted to thecasing 12, whereas when turning the roll-cover element 21′ moves towards thebase plate 11, the cutter moves into a horizontal rest position on the tubular element which from time to time is taken from theroll 22 for the transversal cutting of the latter. - In a variation in construction as shown in
FIGS. 15-17 , thebase plate 11 is not completely separable from the casing or cover above, but only partially. It, in fact has an autonomous front portion, 111, which is for example coupled like a drawer with the remaining part of thebase plate 11 and which is extractable to be washed separately from other parts of the apparatus. In this case, the placing of the roll carrier space being understood, it is thefront portion 111 that is configured to carry theprofiled packing 14 that acts as a locator for thesealing bar 20 and to delimit theslot 15 surrounded by theseal 16 facing thesuction chamber 18 defined by the upper casing. - The connecting
device 13 mentioned above for blocking the casing orcover 12 when closing on thebase plate 11—FIG. 7-9—consists in twofixed hooks 25 and in two correspondingswivel hooks 26. Thefixed hooks 25 extend upwards from opposite parts of thebase plate 11 close to its front side or, when present, from theremovable portion 111. For their rotation, theswivel hooks 26 are mounted onrespective pins 29 and are connected to aturning control shaft 27 by means of an articulation made up ofrelay rods - The control shaft extends crossways and is supported in rotation in the casing or
cover 12, by means of bushings or bearings. - The
swivel hooks 26 are movable between an inactive unblocked position, in which they are at a distance from the fixed hooks—FIG. 7—, and an active blocked position, in which they are drawn near and are closely connected with the fixed hooks—FIG. 9—, by means of a possible intermediate position—FIG. 8—in which hooks and swivel hooks ensure, not so much a clamping, but simply a nearing of the casing or cover on the base plate. - As represented, the
control 27 shaft of theswivel hooks 26 can be a sole item and provided for its manual rotation with levers orend grips 28 positioned externally on the casing orcover 12. - The rotation of the shaft can be carried out manually on one or the other lever or grips or on both at the same time.
- As an alternative, in the place of a single control shaft there can be provided two independent semi-shafts each designed to control a
counter hook 26 and each provided with a relative lever orgrip 28; the two semi-shafts with the relative swivel hooks will in this case be independent, but the block and release of the apparatus when closed may be carried out only by operating on both the levers or grips. - According to another aspect of the invention and regarding a first set up—FIG. 5—to the apparatus to create a vacuum is also keyed a
cam 127 to theshaft 27 or to one of the two semi-shafts, provided to control the block/release 26 swivel hooks. - This cam is set up to engage with a
cursor 128—FIGS. 10-12—which is placed in the casing orcover 12 of the apparatus and helped by means of arelative guide support 129 and configured to control at the same time a bleedvalve 130 associated with the bleed hole on a level with the multiway block and amicro switch 131. In a different set up, the apparatus can be without a bleed valve; in this case the cam fixed to theshaft 27 or to one of the two control semi-shafts of the block/release swivel hooks is always controlled by a cursor, but this is provided only to interact with a micro-switch. - In both cases the micro-switch is inserted in the electric circuit of the apparatus with the aim of enabling the start of the functions of the apparatus itself only when it is blocked and closed, releasing them on the other hand when the apparatus is open.
- The apparatus described above can be programmed to carry out, by means of appropriate selection controls available on the
instrument board 17, for example: all the automatic vacuum formation cycle and sealing starting from a bag with a closed bottom; a shortened soldering and sealing cycle in advance before reaching the maximum vacuum allowed in a flexible container; a soldering cycle without precautionary starting of the vacuum pump when initial sealing of a tubular element to dissect for the preparation of bags is required; a shortened cycle only for the formation of a vacuum in containers that are rigid, positioned outside of the apparatus and connected to it by means of a suction tube. - When the apparatus is not needed, it can be closed, positioning the connecting device in an intermediate blocked condition—
FIG. 8 , and laid down horizontally as inFIG. 1 or placed vertically against the rear side, as inFIG. 2 . - When required for use, the apparatus is opened by using at least one of the levers or grips 28—according to the arrows in FIG. 3—in the direction to release the connecting
device 13 and turn the casing or cover 12 above thebase plate 11—FIG. 4 . At that point, if present, it is possible to extract a length of tubular element from theroll 22 until the end is almost in line with the rear side of the base plate; then close and block the casing or cover 12 on thebase plate 11 using the connectingdevice 13. With the closing of the apparatus, thecam 127 sets, by means of theslider 128, the closing of themicro switch 131 to enable the use of the apparatus. Therefore it is possible to select and proceed with a soldering cycle only, without starting the vacuum pump, to seal the initial part of the tubular element; then re-open the apparatus so as to extract aportion 22′ of tubular element at the required length—FIG. 13—and be able to then lower thetrimmer 23 to trim crossways the length of theportion 22′ from the tubular element so as to be able to have a bag with a closed bottom available. This bag can then be used to arrange the product to be wrapped, after which its open entrance can be placed between the base plate and the casing or cover so as to be in line with the suction chamber. Now, the casing or cover is lowered onto the base plate and blocked on closing by means of a connecting device. So, on the one hand thebleed valve 130 is moved into the closed position of the bleed hole; on the other hand, the micro-switch is closed to enable the operation of the apparatus; consequently the vacuum pump can be started to remove the air from the bag through the suction chamber and, once the empty level required in the bag has been reached, the soldering phase for the final sealing of the mouth of the bag is started before releasing the connecting device again to be able to re-open the apparatus and remove the sealed packet.
