Description

DEVICE FOR CONTROLLING THE DESCENT OF DELICATE PRODUCTS INSIDE THE FORMING TUBE OF A VERTICAL PACKAGING MACHINE
TECHNICAL FIELD
The present invention relates to the technological field of machinery for forming, filling and sealing bags starting off from a roll of flexible material. INTERNATIONAL REFERENCE CLASSIFICATION B 65 D.
BACKGROUND ART
It is well known that when it comes to packaging delicate products the current gravity fed packaging machines with a vertical forming tube manifest all of the
problems deriving from the fragility of the products handled. In packaging machines with vertical forming tubes there continues to be a problem of products breaking as they fall freely inside the forming tube. As the product drops to the bottom of the bag breakage is in fact likely to occur, also resulting in the formation of dust, which compromises the heat-sealing process.
The problem to be solved is precisely that of limiting the drop of the product, i.e. of minimising the height of its free fall to the bottom of the bag. The solution proposed by the present invention enables the product to be accompanied in its descent inside the forming tube and gently conveyed toward
the bottom of the bag to be filled.
The device of the present invention represents a valid solution for the above- described problem. The solution is moreover easy and economical to implement and in prolonged, rigorous trials with highly fragile products it has shown excellent reliability, even at elevated output speeds.
DESCRIPTION
The invention will now be described referring to the figures in the appended drawings, intended as non-restrictive examples.
Figure 1 shows in vertical cross-section the functional layout of the device in question inserted inside the forming tube of a vertical packaging machine. In particular it may be noted that the bottom (5) of the bag, situated at the lower end of the forming tube (2), is already heat-sealed. Also to be noted is the presence of a horizontal shelf (3), stationary in proximity to the upper end of the same forming tube (2). Moreover, particular attention will be drawn to the fact that said shelf (3) is integral with the conveyor belt (1 ), inserted deep inside the forming tube in proximity to the bottom (5) of the bag to be filled. Again in figure 1 one may note the presence of transverse sealing clamps (9) and drive belts (8) driven by their respective motors C and controlled by a computer (7) that also controls in synchronism motor N, which drives the up and down movement of the belt (1). It may be noted that the belt travel (1 ) is reversed by the return roller (4) located in proximity to the bottom (5) of the bag to be filled.
Figure 2 schematically illustrates the start of the phase in which the product is introduced into the forming tube (2). It may be noted that the product, resting upon the horizontal shelf (3) integral with the belt (1), has begun its controlled descent toward the bottom (5) of the bag to be filled. This descent is not a free drop but is rather guided by the computer (7), which electronically controls the speed of motor
N.
Figure 3 schematically illustrates the continuation of the product feed phase. It may be noted that the shelf (3) has been duly lowered according to the quantity of product fed in.
Figure 4 schematically illustrates the arrival of the product, resting upon the shelf
(3), which is still in a horizontal position, in proximity to the return roller (4). It should be noted that the conveyor belt (1 ) has not yet stopped but is slowing down, as clearly shown by the arrows which indicate the controlled rotation of motor N.
Figure 5 schematically illustrates the very particular circumstance in which the shelf (3) is turning downward to allow the gradual transfer of the product to the bottom (5) of the bag.
It shall be highlighted that the gradual angular motion of the shelf (3) is always governed by the computer (7), which controls the rotation speed of motor N.
Particular attention will be drawn to the fact that the transfer of material to the bottom (5) of the bag is not obtained by a gravity-induced free fall but is rather kinematically optimised by the computer (7), which regulates the discharge of the product into the bag.
Figure 6 schematically illustrates the synchronism between the product feed and
simultaneous positioning of the bottom (5) of the bag. This refined synchronism is a further element bringing to light the distinctive functional characteristics of the device of the present invention. The dynamic effects implicit in the variable speed phases are minimised and the fragile, delicate products retain their physical and aesthetic integrity. It shall be noted that both motor N and motors C run under the synchronised control of the computer (7).
Figure 7 schematically illustrates the end of the bag filling phase and the start of
the transverse heat-sealing operation. It may be noted that the transverse sealing clamps (9) have just begun their approach toward the filled bag.
Figure 8 schematically illustrates the completion of the heat-sealing and cutting operation carried out by the transverse clamps (9).
At this point it is worth highlighting the circumstance that the shelf (3) integral with the belt (1), whose motion has been suitably reversed as shown by the new direction of the arrows, is returning into a horizontal position and getting ready to move back up inside the forming tube (2).
Figure 9 schematically illustrates the upward travel of the shelf (3) in the horizontal position. It may be noted that the clamps (9) open simultaneously and the resulting package (6) is detached and lowered onto the conveyance deck in transit below.
Figure 10 schematically illustrates the return of the shelf (3) into the raised position, i.e. the initial phase exactly as shown in figure 1 above.
It may be noted that the resulting package (6) is conveyed away to the dispatch
area.
Figure 11 schematically illustrates a variant and indicates the presence of a
conveyor belt extending as far as the lower end of the forming tube. Figure 12 schematically illustrates a twin solution whereby two conveyor belts are introduced inside a forming tube of double the size. The operating procedure is obviously analogous to the one described with reference to figure 2. In the figures each individual item is marked as follows:
1 indicates the vertical section of a conveyor belt inserted inside a vertical forming tube
2 schematically represents a vertical forming tube
3 indicates a shelf integral with the conveyor belt
4 indicates the lower return roller of said conveyor belt
5 indicates the heat-sealed bottom of a bag to be filled
6 indicates an already formed, filled and sealed bag
7 indicates a computer
8 indicates the drive belts of the flexible material
9 indicates the heat-sealing clamps
10 indicates the collar for wrapping the film around the forming tube
11 indicates the film of flexible material
12 indicates the cutting device
The figures bring to light the simplicity of execution of the solution proposed in the present invention.
In terms of its practical realisation the invention naturally lends itself to many variants, both as regards the dimensions and structural proportions of the various components, as well as the technological choices in respect of the materials to be used in their manufacture. It is evident that the scope of protection of this patent shall extend to all devices for optimising the handling of delicate products during their introduction into a flexible bag which display characteristics as substantially described, illustrated and claimed below.
On being acquainted with the inventive combinations disclosed herein, any technician with average skill in these branches of the art will be able to produce similar devices having functional characteristics derivable by means of simple logical deductions, requiring no inventive effort, but which nonetheless fall within the scope of protection of the present patent industrial patent, simply by reproducing the distinctive inventive characteristics as substantially described,
illustrated and claimed below.
