Definitions
- the present invention relates to an automatic machine for filling and sealing bag-shaped containers made of flexible material, formed by a circular carousel comprising at least two horizontal coaxial discs, the lower disc of which, for conveying the containers, rotates with a continuous circular movement, and the upper disc of which, for supplying the product and sealing the container, is actuated with an alternate circular movement.
- This plant while envisaging that the filling and sealing machine should function with the continuous forward movement of the containers from a first filling carousel to a second sealing carousel, has a few drawbacks due to the fact that the means for gripping and holding the containers themselves are integral with the individual filling and sealing carousels, thereby making it necessary to pick up and release the container itself several times during the course of its travel path inside the machine.
- the said packaging machine has a substantially horizontal extension and is better suited for dimensions intended for high hourly outputs.
- a further type of automatic machine according to the first part of claim 1 is known from FR-A-1.377.643 that discloses a rotating machine equipped with two coaxial discs respectively holding the devices for gripping/opening the bags and the devices for filling/sealing the bags.
- the complexity of the assembly may not allow high production output.
- the technical problem which is therefore posed is that of providing a machine for the filling and automatic sealing of bag-shaped containers made of flexible material, which is suitable for achieving a high production output with minimum dimensions, which does not generate production waste resulting from the spillage of liquid from the containers themselves, which is easy and economical to install and can be supplied with individual bags picked up by suitable loaders associated with the machine itself.
- the machine 100 is substantially composed of a fixed base 101 which has mounted on it a carousel 102 which comprises two circular coaxial surfaces, i.e. a lower one 200 and upper one 300 respectively.
- the lower surface 200 which forms the surface for supporting and conveying the containers 1 removed from a feeder 2 by means of a synchronising loader 400, is made to perform a continuous rotating movement while the upper surface 300, to which the devices for metering the product to be supplied to the container 1 and the devices for sealing the latter are rigidly connected, is made to rotate in accordance with an alternate movement.
- the machine according to the invention is moreover provided with a conveyor belt 500 for conveying away the sealed containers, which are removed from the carousel 102 and deposited onto the belt 500 by means of a synchronising arm 600.
- the base 101 has rigidly connected to it a motor 101a which, via the drives 102a, actuates a splined shaft 103, arranged parallel to the vertical axis of the carousel 102, by means of which the surface 200 supporting the containers 1 is made to rotate with a continuous movement.
- the disc 200 in the region of its external edge, carries devices 201 for gripping and holding the container 1, which devices form the subject of a contemporary patent application in the name of the same Applicant and will be described only briefly.
- Said devices 201 are arranged at regular angular intervals along the entire circumference of the disc 200 and are rigidly connected to the latter by means of a threaded shank 201a and a ring-nut 201b; in this way the holding devices 201 rotate rigidly with the disc 200, travelling simultaneously via rollers 201c on a further disc 202 which is locked in rotation and the upper surface 202a of which has a cam profile designed to cause actuation of the gripping and holding devices 201 by means of the symmetrical movement towards/away and closing/opening of the jaws 201d onto/from the sides of the container 1 (see Figure 4a).
- the disc 202 is moreover rigid in the axial direction with the disc 300 and together with the latter adjustable heightwise with respect to the surface 200 by means of a screw 301 actuated by a motor 301a and acting on a female screw 301b connected to a hollow shaft 302, the upper end of which is fixed to the disc 300.
- the hollow shaft 302 is moreover connected to a first transmission 104 actuated via suitable means 105 by the splined shaft 103 and with a second transmission actuated by a cylinder designed to cause a counter-rotation through a predetermined angle of the surface 300 with respect to the surface 200.
- the hollow shaft 302 is moreover keyed onto a bush 307 provided with a radial arm 307s at the end of which there is arranged a cylinder 307b, the rod of which actuates a stud 307c movable axially for coupling with a corresponding seat 104c formed in the transmission 104.
- the devices 310 for opening the upper mouth of the container 1 are integral with the disc 300 and substantially consist of a bracket 311 movable along a circumferential arc concentric with the carousel and defined by a guide 311a along which the support travels via rollers 311b and as a result of the thrusting and recall action of the rod 312a of a cylinder 312.
- Said suction cups can therefore be actuated symmetrically in the radial direction both towards and away from the surfaces of the front sides of the container 1 so as to cause opening thereof prior to filling.
- Figures 1 and 2 also show the devices 320 for sealing the container, substantially consisting of heat-welding grippers 321 actuated so as to open/close via a motor 322 arranged on the plate 300 and drives only schematically indicated by 323 and designed to cause the said grippers to open and close symmetrically with respect to the container.
- the containers 1 are removed from a feeder 2 via a synchronising loading arm 400 consisting of a horizontal arm 401 which rotates through a predetermined angle about an axis parallel to the axis of the carousel and the end of which opposite to the end hinged with the base 101 has mounted on it an arm 402 perpendicular to the arm 401 and rotating about its own axis of vertical symmetry.
- the suction cups 403, arranged in the transverse direction with respect to the vertical arm, are rigidly connected to said vertical arm.
- the containers 1 are removed from the feeder 2 ( Figures 1 and 3) by means of the suction cups 403 arranged on the arm 402 of the synchronising loader 401 and from here brought into a predetermined angular position with respect to which the container is arranged in a tangential position at a relative speed of zero compared to the disc 200 carrying the gripping devices 201 which, in said angular position, close around the lateral edges of the container ( Figure 4a), removing it and starting to convey it along the circular path inside the carousel.
- the container passes underneath the device 310 ( Figure 4a) for opening the mouth of the container 1, the device actuated by the cylinder 312 follows the container along a section of the circumference, causing opening thereof by means of actuation of the suction cups 315 towards and then away from each other in the radial direction ( Figures 4b, 4c).
- the container is ready to be filled and is brought by the disc 200 underneath the filling station 303 rigid with the disc 300 which during this stage is rigidly connected to the splined shaft 103 by means of the transmission 104 so that the conveying disc 200 and the upper disc 300 carrying the metering devices 303 and the sealing grippers 321 travel integrally along a predetermined circumferential arc corresponding to the production capacity of the machine.
- This circumferential arc is determined by the time required to carry out filling and sealing of the container. As can be seen from the Figures and as is obvious for a person skilled in the art, in the example shown this circumferential arc is divided up, filling and sealing also being divided up so as to allow simultaneous filling and sealing of a plurality of containers in order to increase the productivity of the machine.
- the transmission 104 is disengaged from the shaft 103 and at the same time the stud 307c is retracted from the seat 104a which caused coupling of the disc 300 to the disc 200 and instead the transmission 106 activated which, actuated by the cylinder 107, brings the disc 300 back into the initial position with a counter-rotational movement, while the disc 200 for conveying the containers 1 proceeds along its continuous path transporting the containers 1 as far as the arm 600 for unloading them onto the belt 500.
