Definitions
- the invention relates to the technical field of packaging of various products and, more particularly, food products in the context of artisanal or semi-industrial manufacturing.
- a device having a base provided with a housing for receiving at least one container or tray. On this base is fixed a tilting frame from a raised position, called rest, to a lowered position, called working, in which heating means are pressed against the cover and the container to be closed.
- the maneuvering of the movable chassis is more generally ensured by an operator who determines, by the intensity and the duration of the force which he exerts manually on the chassis, the sealing pressure and the heating time of the heat-sealable cover.
- a lack of control of these parameters by an operator, inexperienced, or having to ensure a high rate of work can lead to poor sealing of the seal. This poor closure can then lead, over time, to degradation of the product packaged in the container.
- the above sealing device has, given the tilting movement of the movable frame, a relatively large size. Indeed, it is necessary, so that the raised chassis occupies a stable position without risk of inadvertent closure on the hands of the user, during the placement of the container, provide a movement with an amplitude greater than 90 °.
- air springs can also be used to hold the tilting chassis in the raised position, in which case the movement has an amplitude of approximately 60 °. If such a design makes it possible to reduce the operating space requirement of the device, it does not make it possible to release, in a satisfactory manner, the receiving housing for the positioning of the container and of the cover. In addition, given the position of the chassis in the raised position, the user is liable to burn himself on the heating means when handling the container.
- the invention relates to a new device for lidding various containers, of the type having a base provided with a housing. for receiving at least one container and a frame which is provided with at least one means for fixing a cover or the like on the container and which is movable, between a so-called rest position and a position above the housing, called of work.
- this device is characterized in that it comprises means for connecting the chassis with the base, allowing movement of the chassis between the working position and a position offset on the side of the housing which corresponds to the position of rest and in which the fastening means has, relative to the vertical, an orientation substantially similar to its orientation in the working position.
- the connecting means comprise:
- the device comprises at least one means for balancing the weight of the chassis, so that the chassis occupies a stable position anywhere in its travel path.
- the device comprises at least one means for controlling the intensity of the pressure exerted by the fixing means and, insofar as the fixing means comprises at least one heating means, the device comprises, according to yet another characteristic of the invention, means for controlling the temperature of the heating means as well as means for controlling the duration of pressure exercise.
- the device comprises, at the level of the housing, an adjustable cradle as a function of the size of the container to be sealed.
- the receptacle for receiving the container is open laterally and includes an opening cradle to allow lateral introduction of the container.
- Figs. 1 and 2 are perspective views showing an embodiment of the sealing device according to the invention, respectively in the rest position and in the working position.
- Fig. 3 is an elevation along the plane m-DI of FIG. 1 of the sealing device according to the invention.
- Fig. 4 is a section along the TV-TV plane of FIG. 1 showing a detail of the mobile chassis constituting the device according to the invention.
- Figs. 5 and 6 are elevations showing the device according to FIG. 1 respectively in the rest position and in the working position.
- Fig. 7 is an axial section showing a preferred but not exclusive embodiment of the connection means between the base and the chassis of the device according to the invention.
- Fig. 8 is an elevation similar to FIGS. 5 and 6 showing an intermediate position of the mobile chassis of the sealing device.
- Fig. 9 is a top view showing an adjustable cradle system according to the invention.
- Fig. 10 is a perspective similar to FIG. 1 showing an opening cradle according to the invention.
- Fig. 11 illustrates in section an embodiment of the invention, of an automatic device for cutting the cover.
- Fig. 12 illustrates another embodiment of the sealing device according to the invention.
- the device for sealing various containers comprises a base 2 provided with a housing 3 for receiving a container 4 intended to be sealed .
- the container 4 is constituted by a tray, of substantially parallelepiped shape, having a wing or peripheral area 5 for sealing a seal.
- the device 1 comprises, for the reception of such a container at the level of the housing 3, a cradle 6 in which the container 4 engages to come to rest in the cradle 6 by its peripheral surface 5.
- the device 1 for the sealing of the container 4 also comprises a frame 7 which is provided with at least one means 8 for fixing a cover or the like on the container 4.
- the fixing means 8 is designed for heat sealing a thermoplastic cover on the container 4.
- the fixing means 8 then comprises a pressure plate 10 carrying at least one heating element 11, such as for example an electrical resistance.
- the heating element 11 is connected to a regulation block 12 which is connected by lines 13 to a temperature sensor 14 in relation to the plate 10.
- the chassis 7 is movable relative to the base 2 and connected to the latter by connecting means 15 which allow movement of the chassis 7 between a rest position A offset on the side of the housing 3, such that 'illustrated in fig. 1 and 5, and a working position B located above the housing 3, as shown in FIGS. 2 and 6.
- the fixing means 8 has, with respect to the vertical, substantially the same orientation in the rest position A and in the working position B.
- the fixing means 8 has a horizontal extension plane in the rest position A and in the working position B.
- its face carrying the means fixing 8 preferably has always substantially the same orientation directed downwards.
- the connecting means 15 can be produced in any suitable manner and the movement of the chassis 7, when it moves between positions A and B, can be a translation, a rotation or even a combination of one or more of these two types of movement.
- the connecting means 15 can, for example, be made so that the frame 7 moves in translation between position A and position B.
- the connecting means 15 comprise a sliding pivot with a substantially vertical axis XX ′.
- the chassis 7 then moves between a high rest position A and a low working position B by performing a combination movement of a translation of direction X-X 'and of a rotation around this same direction X-X'
- the connecting means 15 comprise a hinge pin 16 secured to the frame 7.
- the hinge pin 16 is, moreover, guided in translation and in rotation by bearings 17 arranged in a bore 18 of axis XX 'arranged in the chassis 2.
- the axis XX ′ and the bore 18 are offset with respect to the housing 3, so that the connection means
- the hinge pin 16 is hollow to form a passage for the power cables of the heating element 11.
- the connecting means 15 comprise at least one means 19 for balance the weight of the chassis 7.
- This balancing means 19 comprises, for example, a helical spring interposed between the chassis 7 and the base 2 while being mounted coaxially with the articulation axis 16.
- the means of balancing 19 could be achieved in another way and include, for example, an air spring.
- the sliding pivot thus formed is, moreover, completed by a helical cam 20 carried by a flange 21 secured to the hinge pin 16.
- the helical cam 20 cooperates with a roller secured to the base 2, so that the rotation of the chassis 7, from the rest position A in the direction of the arrow Fi, brings the chassis 7 into an intermediate waiting position C, illustrated in FIG. 8, in which the chassis 7 is in a position superimposed on that of working B but at a distance therefrom.
- the connecting means 15 then comprise at least one means 23 for moving the chassis 7 between the waiting position C and the working position B.
- the means 23 are motor and are, for example but not exclusively, constituted by an electromagnet which, when excited, attracts the flange 21 in the direction of arrow F 2 , so as to lower the chassis 7.
- the displacement means 23 constitute an electromagnetic lock.
- the electromagnet 23 is connected by lines 25 to a control unit 26 carried by the base 2.
- the 23 is inserted in a fixed flange 28, complementary to the plate 21 and integral with the base 2.
- the two flanges 21 and 28 each have two flanges, respectively internal 29] and external 29 2 , defining a housing for the coil and channeling the lines magnetic field during operation of the electromagnet.
- the internal flanges 29 2 have, at their opposite ends, a complementary step.
- the electromagnet makes it possible to obtain a calling force at the level of the articulation axis 16, when the chassis is in intermediate position C, of the order of 15 to 17 daN, then reaching 200 daN when the flanges are close together and the chassis in working position B.
- the displacement means 23 could not be motorized and constituted for example by a lever acting on an eccentric cam pressing on the flange 21 to lower the chassis 7 in the direction of the arrow F 2 .
- the sealing device according to the invention and as described above, is implemented in the following manner.
- the tray 4 to be sealed is placed in the cradle 6 of the housing 3.
- a cover 30, shown in phantom in FIG. 1 is placed on the tray 4 and its content, not shown.
- the cover 30 is formed by a length of heat-sealable film delivered by a reel 31 carried by a reel 32 fitted to the base 2.
- the frame 7 overhangs the reel 32 in the rest position A, as shown in fig. 5.
- the chassis 7 is then moved in rotation, in the direction of the arrow Fi, by an operator so as to come and place the chassis 7 in the standby position C.
- the control means 26 then supply the electromagnetic suction cup 23 to move the chassis in the direction of the arrow F 2 and press the fixing means 8, and more particularly the heating plate 10, against the heat-sealable film and the surface. 5 of the tray 4.
- the hinge pin 16 bears against an adjustable stop 33, so as to allow an adjustment of the downstroke between positions C and B.
- the stop 33 is, in addition, equipped with an elastically deformable damping element 34 which reduces the noise resulting from the impact between the hinge pin 16 and the stop 33.
- the implementation of the electromagnet, illustrated in fig. 7, makes it possible to exert, at the end of the call stroke, a force of the order of 150 daN at the level of the chassis 7.
- the operation of the heating element 11 and the temperature to which the plate 10 is brought are controlled by the regulating block 12 which includes adjustment means, in order to be able to adjust the temperature of the plate 10 as a function of the material and the thickness of the film forming the cover 30.
- the control block 12 maintains the plate 10 at an appropriate temperature, of the order of 160 ° C for example.
- the regulating block 12 comprises adjustment means making it possible to fix the temperature at a value between 0 and 250 ° C.
- control means 26 maintain the supply of the electromagnetic lock 23 for a given duration, in order to perfectly control the duration of application of the heat to the cover 30. So preferred, the control means 26 have adjustment means to allow an adjustment of the duration of application of the heating plate 10 on the cover 30.
- the invention provides, according to a preferred but not strictly necessary characteristic, to implement means 35 for controlling the intensity of the pressure exerted by the fixing means 8 on the cover 30.
- these control means 35 are constituted by elastically deformable elements, such as for example helical springs, interposed between the fixing means 8 and the chassis 7.
- these springs 35 are prestressed , so that the optimum sealing pressure is reached with a relatively reduced chassis travel 7.
- the means 35 for controlling the pressure exerted could be produced in another form, making use, for example, of jacks or the like.
- the chassis 7 has a rotational stroke, between positions A and B, of approximately 90 °. It should be noted that, taking into account the presence of the compensation spring 19, the chassis 7 occupies, in all places of its movement between A and C, a stable position.
- the kinematics according to the invention of the connection between the base 2 and the chassis 7, allows to obtain, in the rest position A, complete clearance of the housing 3 and the cradle 6, so that, on the one hand, the establishment of the container and its cover and, on the other hand, the removal of the closed container are simple and without risk for the user.
- the kinematics used makes it possible to obtain a semi-automatic sealing device 1 having a small footprint in operation.
- the cradle 6, equipping the housing 3, has a single imprint intended to receive a single container.
- the cradle 6 could be multi-fingerprints and allow the simultaneous establishment of several containers in the housing 3.
- the cradle 6 could be interchangeable with cradles of different sizes.
- the cradle 6 is adjustable, so as to be able to take care of containers having different sizes and, in particular, a different length, while keeping a constant width.
- the cradle 6 comprises two half-cavities, one of which 6 ⁇ is integral with the base 2, while the other 6 2 is movable in translation between a position G in maximum extension illustrated in dashed lines in FIG. 9 and a position P of minimum retraction illustrated in solid lines in this same figure.
- the immobilization of the movable half-footprint 6 2 is then achieved by blocking means not shown.
- the fixed half-imprints 6 1 and mobile 6 2 have an "L" shape, but they could have another shape.
- the minimum extension position p of the movable half-impression is located at a distance from the fixed half-impression 61, but it could also be envisaged that the minimum extension position of the mobile half-impression 6 2 is in contact with the fixed half-impression 6d.
- the movable half-imprint 6 2 can pivot in the plane of the cradle 6, so as to open the latter to allow lateral introduction, in the direction of the arrow Fj 0 as illustrated in FIG. 10, of the container 4 in the housing 3.
- the housing 3 is also open laterally.
- the half-cavity 6 2 could not be sliding, so that the cradle 6 could be opened without being adjustable in size.
- the opening and / or adjustable cradle 6 is integrated into the base 2.
- the cradle 6 could be produced independently and attached removably to the base 2.
- the device for sealing various containers presented above implements a seal constituted by a film delivered by the reel 31.
- the device 1 preferably, but not necessarily, includes an automatic cutting system involving a fixed knife 36 secured to the chassis 7 and a cutting groove 37 secured to the base 2 as illustrated in FIG. 11.
- the stationary knife 36 is completed by retractable blank clamps 38.
- the groove 37 defines a section plane P raised relative to the opening plane of the housing 3, so that it is not necessary to arrange grooves in the movable cavity 6 2 to take into account the stroke of the knife 36.
- Fig. 12 illustrates another embodiment of a device 1 according to the invention for vacuum packaging or under controlled atmosphere of various containers.
- the device 2 implements the same kinematics as that of the device described above for the connection 15 and the movement of the chassis 7 relative to the base 2.
- the receiving housing 3 forms a tank intended to be closed in the working position of the chassis 7 by a complementary cover 40 carried by the chassis to form a substantially sealed enclosure.
- the fixing means 8 are placed at a distance from the container 4 and from the cover 30.
- the chassis 7 then comprises means 41 for pressing the fixing means 8 against the cover and / or the container and to raise them after fixing the cover.
- the device 1 is supplemented by means 42 for bringing the chamber formed by the tank and the cover 40 into relative depression.
- the means 41 are connected to the tank by at least one pipe 43 and the base 2 comprises a pipe 44 connecting the tank 3 to the volume defined by the cover 40, so as to allow the establishment of the vacuum in the whole of the sealed enclosure.
- the latter also comprises means 45 for injecting a fluid, such as an inert gas such as nitrogen, into the sealed tank. These means 45 are then connected to the tank 3 by a pipe 46.
- the operation of the device 1 thus formed is carried out as follows. After introducing the container 4 into the tank 3 and fitting the cover 30, the operator places the chassis 7 in the intermediate waiting position C.
- the block 26 then controls the supply of the electromagnet 23 to lower the chassis 7 to the working position, close the tank 3 by the cover 40 and form the sealed enclosure.
- the means 42 then ensure a vacuum of the sealed enclosure.
- the means 45 inject a gas into the enclosure.
- the pipe 46 opens into the tank 3 and under the cover 30 to ensure the injection of gas directly between the cover 30 and the container 4.
- the means 41 press the fastening means 8 to secure the cover 30 to the container 4.
- the fixing means 8 preferably comprise a knife 47 constituting a cookie cutter in the shape of the container, so that the the lid is cut when it is fixed to the container.
- the fixing means are constituted by a heating plate 10 without imprint, but they could also be constituted by a single or multi-imprint heating plate having, for example, the cutting means in the form of the sealed lids.
- the fixing means could also be constituted by a crimping head, insofar as the container calls for this type of closure, or even by a simple non-heating pressure plate.
- the cover is not necessarily formed by a heat-sealable film, but could be constituted in any suitable manner, depending on the type of container used.
- the cover could, for example, be made of treated cardboard or even in the form of a plastic cover, integral or not with the container.
- the entire movement between positions A and B could be motorized.
- the movement of the chassis could also involve no motor and be provided manually by the user of the device 1 according to the invention.
- the invention finds a preferred industrial application for the packaging of food products.
