    EXCHANGEABLE ULTRASONIC WELDING MODULE FOR WELDING LONGITUDINAL REINFORCING FOLDS IN PACKAGING FILM INSIDE PACKAGING MACHINE AND METHOD OF ITS USE
    Technical Field
    This invention relates to an exchangeable ultrasonic welding module for welding longitudinal reinforcing folds in packaging film inside packaging machine and to a method of its use. The invention belongs to a technical field involving machines, appliances or equipment for packaging products or commodities. The invention can be used with both vertical and horizontal form-fill-seal flat film packaging machines.
    Background Art
    Where products or commodities are packaged in tubular-shape sachets using packaging machines, a requirement often arises for reinforcing such sachets with longitudinal folds. Sachets with such folds effectively retain their shape. These sachets generally contain two, three or four longitudinal reinforcing folds.
    In packaging machines, longitudinal reinforcing folds, arc shaped using forming elements and welded by means of electrically-heated welding modules or ultrasonic welding modules or various types.
    An advantage of ultrasonic welding modules over electrically-sealed devices is their small size. Due to their use in a form-fill-seal flat film packaging machine does not increase the machine's total installation height or the drop height of tire product or commodity, which might otherwise pose a greater risk of damage to the product or commodity. Another advantage is that they are easy to arrange around the filling tube, which allow filling tubes with optimum cross-sections to be used, and thus eliminate problems with products or commodities clogging in the filling tube.
    Disadvantages of ultrasonic welding devices include their higher price, the need for precise relative adjustment of welding tools, i.e. the horn and the anvil, and the need for precise positioning of said ultrasonic welding modules with respect to the filling tube and the forming elements. The solution according to this invention eliminates these disadvantages to a considerable extent.
    Disclosure of Invention
    The essence of the invention is the design of an exchangeable ultrasonic welding module for welding longitudinal reinforcing folds in a packaging film inside a packaging machine. In particular, it relates to the design solution for said modules disposed around the filling tube and to the method of their use or, more specifically, the method of their exchange.
    The exchangeable ultrasonic welding module contains a standard ultrasonic transducer assembly with a horn. The horn is oriented opposite to an amil and the path of the film to well-done passes between them. In this arrangement, the horn can be adjusted with repeatable precision with respect to the anvil, and therefore can operate trouble-free.
    The module also contains a member provided with a guideway for guiding a sliding motion along one axis within the mating guide provided on the filling tube frame. One particular embodiment of the mating guideway involves a shaped groove with one end open to allow the member's guidewav or an analogous shape to slide in and out. The guidewav or the member is inserted all the way into the mating guidewav.
    The member and / or the frame contain a locking element which secures the member and the frame in a fixed position relative to each other. The locking element may take the form of a screw or a clamping joint. The member is further provided with an element for linear motion of a sliding carriage and with an adjustable stop which restricts the movement of the carriage or, more specifically, defines its end position. The element for linear motion of the carriage may include, in particular, a pneumatic cylinder, a servo drive with a threaded rod, or a similar device. A less advantageous but functional solution involves a hand-operated device, e.g., a hand-operated threaded rod. The ultrasonic transducer assembly is firmly affixed to the carriage, whereas the anvil is affixed to the frame. Utilities are supplied to the module via a combined connector with a cable. The linear motion of the carriage with the ultrasonic transducer assembly with respect to the anvil is particularly desirable for repair tasks or for introducing new film. Thanks to the principle of ultrasonic welding, the module is not hot and there is no risk of undesirable damage to the film, thus it is not necessary to open the module after the end of welding.
    Preferably, the frame contains an adjustable stop to secure the member in a defined position as the member is inserted in the mating guideway. This is important for achieving a correct position of the module with respect to that filling tube. If no adjustable stop is provided, the end of the mating guide can determine the position of the inserted member. However, this is only possible when the contact surfaces of the guidewav and its mating guidewav (more specifically, the member and the frame) have been produced to great precision.
    Such arrangement allows the exchangeable ultrasonic welding module to be adjusted with repeatable precision with respect to the filling tube and to the forming elements, and therefore allow its use with multiple filling tubes for producing various formats or sachets by the user. The specific arrangement of exchangeable ultrasonic welding modules around the filling tube and their number depends on the desired shape of the transverse cross-section of the sachet, on the transverse cross-section of the filling tube, and is outside the scope of this invention.
    The designs described above enable costly ultrasonic welding modules to be employed using a newr and effective method according to the invention. This invention relates to a method of use of this exchangeable ultrasonic notification module or, more specifically, to a method of exchanging it between different filling tubes. The number of filling tubes is not limited. The procedure comprises the following steps: - removing a complete first filling tube, which is fitted with forming elements and exchangeable ultrasonic welding modules, from a packaging machine, - unlocking the locking elements and sliding out the exchangeable ultrasonic welding modules from the mating guide on the frame of the first filling tube, - sliding the exchangeable ultrasonic w elding modules all the way into the mating guide on a second filling tube, - placing the second filling tube, which is fitted w ith forming elements and exchangeable ultrasonic welding modules, into the packaging machine.
    The stop in the mating guide way on the filling tube frame may preferably take the form of an adjustable stop.
