Abstract

This invention relates to a continuous motion vertical form, fill and seal machine in which an initially flat foil or web of plastics material roll stock is folded and welded into a tube 12.3 which is conveyed through the machine 10. Instead of a single set of gripping jaws, the FFS machine 10 has two sets of gripping and sealing jaws 22 that grip, seal and cut the tube at predetermined intervals to form a plurality of bags 12.4. Each set of jaws 22 is mounted on a tracked carriage 26 that is mounted for reciprocating travel along a set of rails 28 that extend vertically on each side of and parallel to the travel path of the foil tube 12.3. The jaws 22 are horizontally reciprocable by means of hydraulic rams 30 that open and close the jaws 22. The jaws 22 are adapted, when moving with the tube 12.3, to close and grip the tube 12.3 and to open when moving counter to the tube 12.3 and the opening and closing of the jaws 22 is synchronised so that at least one set of jaws 22 is in grip contact with the tube 12.3 at all times (in use) and the opening of the jaws is 22 adapted to allow the jaws 22 that are not in grip contact, when in use they return to their starting position, to bypass the jaws 22 that are in grip contact with the tube 12.3.

Description

CONTINUOUS MOTION VERTICAL FORM, FILL AND SEAL MACHINE
Background to the invention
This invention relates to a continuous motion vertical form, fill and seal machine.
A form, fill and seal (FFS) machine typically takes a flat roll of plastics sheet material, forms it into a tube which is then formed into a plurality of bags. The bags are filled automatically and then sealed. The process is usually fully automated.
Although so-called "continuous motion" FFS machines are known, their operation in reality is no more than semi-continuous.
It is an object of this invention to address this shortcoming.
Summary of the invention
According to this invention a fill and seal machine comprises means to convey a tube of plastics sheet material through the fill and seal machine and at least two sets of gripping and sealing jaws adapted to grip, seal and cut the tube at predetermined intervals to form a plurality of bags, characterised in that:
each set of jaws is mounted for reciprocating travel on each side of the travel path of the tube for travel along the travel path of the tube and for reciprocating travel in a direction normal to the travel path of the tube, in use to close on and grip the tube and to open away from the tube; the jaws being adapted to move, in their reciprocating travel along the travel path of the tube, from a starting position, in synchronicity with the tube and in the travel direction of the tube, to a point remote from the starting position and to return to the starting position in a direction counter to the travel direction of the tube;
the jaws being adapted to move, in their reciprocating travel normal to the travel path of the tube, from a starting position in which the jaws touch, with the tube gripped between them in use, to a position in which they are open and remote from the tube travel path;
the jaws being adapted, when moving with the tube, to close and grip the tube and to open when moving counter to the tube;
the opening and closing of the jaws being synchronised such that at least one set of jaws is in grip contact with the tube at all times in use; and
the opening of the jaws being adapted to allow the jaws that are not in grip contact, when in use they return to their starting position, to bypass the jaws that are in grip contact with the tube.
It stands to reason that the jaws are constrained, when in grip contact with the tube, to move at the tube travel speed.
In the preferred form of the invention, however, the jaws are adapted to move, during return travel, at a speed greater than the tube travel speed, to bypass the jaws in grip contact and to emerge, at their starting position before the jaws in grip contact have released the tube, thereby enabling the jaws at the starting point to close and grip the tube and to start their cycle of movement in grip contact with the tube, thereby to ensure that both sets of jaws are momentarily in grip contact with and moving in the travel direction of the tube. This will ensure continuous tension on the tube.
The fill and seal machine of the invention may include means to convey the tube through the machine, such as a belt drive, but in the preferred form of the invention, no such conveying means is necessary since the jaws draw the tube through the machine.
The machine is preferably a form, fill and seal machine adapted to form plastics sheet material into a tube prior to the conveyance of the tube through the machine and more preferably a vertical form, fill and seal machine.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings in which:
Figure 1 is a diagrammatic front elevation of a form, fill and seal machine according to this invention;
Figure 2 is a diagrammatic section on a line 2 - 2 in Figure 1 ; and
Figure 3 is a diagrammatic section on a line 3 - 3 in Figure 1.
Description of embodiments of the invention
The form, fill and seal (FFS) machine 10 illustrated in the drawings begins with a preprinted roll stock web or foil (illustrated in dotted outline 12 in Figure 1) that is loaded onto material reels (not shown) located at the rear of the form, fill and seal machine 10. The roll stock is initially flat and is fed into the FFS machine 10 over a folding collar 14 that forms the initially flat roll stock 12.1 into a tubular foil preform 12.2.
As can be seen from Figure 2 in particular, the preform 12.2 is then drawn through a vertical heat welding station 16 by means of a belt drive 18 made up of tractor belts that bear against a tubular bag former 20 where the preform 12.2 is sealed longitudinally by means of a vertical heat welding station 16 into a foil tube 12.3.
The foil tube 12.3 is then fed into the grip of a set of gripping and sealing jaws 22 fitted with heat welding elements as well as a guillotine or knife (not shown) by means of which bags 12.4 can be cut loose from the foil tube 12.3 when each bag 12.4 has been formed, filled and sealed. The jaws grip and seal the base of one bag 12.4 and the top of the filled bag 12.4 immediately therebelow, cutting that filled and sealed bag 12.4 free and then opening the jaws 22 to start the cycle over again.
Conventional form, fill and seal machines are provided with a single set of gripping and sealing jaws, but the form, fill and seal machine 10 of this invention is provided with a pair of mechanically independent sets of jaws 22.1 , 22.2.
Each set of jaws 22 is mounted on a tracked carriage 26 that is mounted for reciprocating travel along a set of rails 28 that extend vertically on each side of and parallel to the travel path of the foil tube 12.3 within the FFS machine 10. The reciprocating travel of the jaws along the rails 28 takes place in the travel direction of the tube 12.3.
The jaws 22 on each carriage 26 are horizontally reciprocable across the carriage by means of hydraulic rams 30 that open and close the jaws 22 as and when required (see Figure 3 in particular). The reciprocating travel of the jaws 22 along the carriages 26 takes place in a direction normal to the travel direction of the tube 12.3.
The jaws 22 are fitted with heat welding elements as well as a guillotine or knife (not shown) by means of which bags 12.4 can be cut loose from the foil tube 12.3 when the bag 12.4 has been formed, filled and sealed.
In use and with the jaws 22 in the start position, both sets of jaws are wide open to allow the full diameter of the foil tube 12.3 to pass. The first set of jaws 22.1 is positioned at the top of their vertical stroke and the second set of jaws 22.2 is positioned at the bottom of their vertical stroke on the rails 28.
At startup, the foil tube 12.3 is drawn through the vertical form, fill and seal machine 10 at a predetermined speed by means of the belt drive 18.
When an "eye" mark printed on the foil tube 12.3 passes a photocell located adjacent the travel path of the foil tube 12.3, a signal activates the first set of jaws 22.1. First the rams 30.1 close the jaws 22.1 and the jaws 22.1 then start to move downwards on the rails 26.1.
When fully closed, the first set of jaws 22.1 start a programmed cycle of sealing the base of the bag 12.4 and the top of the filled bag 12.4 immediately therebelow. The downward movement of the first set of jaws 22.1 continues until a signal, prompted by the eye mark passing a photocell, causes the FFS machine 10 to activate the jaws 22.1 to cut the filled and sealed bag 12.4 free and to activate the rams 30.1 to open the first set of jaws 22.1.
The FFS machine 10 is programmed first to open and then to stop the first set of jaws 22.1 which then come to rest at the lower end of the vertical travel of the carriage 26.1 on the rails 28.1.
Once the first set of jaws 22.1 have started their downward movement and are fully closed, the second set of jaws 22.2, still in their open position, starts to move upwards from the lower to the upper end of the vertical travel of the carriage 26.2 on the rails 28.2. Since there is no need to synchronise this reciprocating movement of the second set of jaws 22.2 with that of the foil tube 12.3, the first set of jaws 22.1 can be set to travel upwardly at much greater speed than the downwards movement. Since the second set of jaws 22.2 are open, they bypass the downwardly moving first set of jaws 22.1 around the outside.
At the upper end of the vertical travel of the carriage 26.2 on the rails 28.2. the second set of jaws 22.2 come to rest and await the signal to start their clamping, sealing and cutting cycle. When the next eye mark on the foil tube 12.3 passes the first mentioned photocell, a signal activates the second set of jaws 22.2 to move downwards on the rails 26.2. At the same time, the rams 30.2 close the jaws 22.2.
When fully closed, the second set of jaws 22.2 start a similar programmed cycle to that described above of sealing the base of the bag 12.4 and the top of the filled bag 12.4 immediately therebelow, cutting that filled and sealed bag 12.4 free, opening and then coming to rest at the lower end of the vertical travel of the carriage 26.2 on the rails 28.2.
In the meantime, the first set of jaws 22.1 , still in their open position, starts to move upwards from the lower to the upper end of the vertical travel of the carriage 26.1 on the rails 28.1 , bypassing the downwardly moving second set of jaws 22.2 around the outside.
At the upper end of their vertical travel the first set of jaws 22.1 comes to rest and awaits the signal to start their next clamping, sealing and cutting cycle.
This process is simply repeated thereby providing a continuous forming, filling and sealing process that does not compromise the welding and cooling time required in respect of certain types of plastics sheet materials.
It is also possible, using the continuously operated jaws 22 of the form, fill and seal machine 10 of this invention, to do away with the tractor belt drive 18 and simply to use the jaws 22 to draw the foil tube 12.3 through the form, fill and seal machine 10. This might require manual positioning of the foil tube 12.3 eye mark at startup and the jaws 22 will have to be programmed to ensure that the downward movement of the first set of jaws 22.1 continues until the second set of jaws 22.2 has started its cycle in order to secure continuous tension on the foil tube 12.3.
