Definitions

the invention relates to a method and a device for preparing the parallel production of in particular tubular bag packs with a small width from a packaging material web cut into several strips of the same width, the strips being molded continuously and clocked onto a corresponding number of shaped tubes and being longitudinally sealed.
Parallel production is understood to mean that a corresponding number of tubular bag packs are produced simultaneously and next to one another on a number of parallel shaped tubes.
tubular bag With regard to the tubular bag, reference is made to DE-U-93 12 664. These tubular bag packs have relatively small dimensions, i.e. a width of only about 2 cm and a length of about 10 to 15 cm.
Such tubular bags are manufactured with a device which consists of packaging material web transport elements arranged on a device frame, a strip cutting device with molded tubes arranged behind one another in series, each with a strip width and corresponding in circumference of the strip width, to which guiding elements, provided that there is no overlap sealing for the sealing strips and from packaging material web-forming elements which can be placed on both sides of the cylindrical shaped tubes, longitudinal sealing tools being arranged behind them in the conveying direction and behind the shaped tube ends a transverse cutting device, which is followed by a transverse sealing tool which can be moved up and down.
the cut strips are formed in such a way that the abutting edges of each strip lie centrally over the inserted sealing strips and are sealed longitudinally with them, after which the packaging tubes formed are sealed behind the ends of the molding tubes, pulled off the desired bag length and cut off from the following packaging tube become.
the invention is therefore based on the object to provide a method and a device for preparing the actual parallel production of tubular bag packs of the type mentioned or to improve the devices used hitherto in such a way that the previously difficult and relatively time-consuming process of forming the strips on the shaped pipes is eliminated .
this object is achieved according to the invention in that the longitudinal cuts for the strip division of the packaging material web only begin after an uncut advance of the packaging material web, the beginning of cuts in the packaging material web with this led to at least the ends of the shaped tubes, then first the strips in the middle and then the strip edges are applied to the shaped tubes and sealed longitudinally and the uncut lead of the packaging material web is cut off after a first transverse sealing.
the difficult and time-consuming threading and shaping work of the individual strips on the shaped tubes in the confined space conditions is eliminated, i.e. the packaging material web to be cut into strips can be inserted into the device as in the production of normal tubular bag packs be introduced and this then continues in the normal way as before after the start cycle to be controlled in particular.
the whole thing is bought with a small loss of packaging material, but this is out of all proportion to the difficulties that have so far been encountered in order to be able to start such devices at all.
the strips created as a result of the subsequent cut are held together, no longer hang freely downwards and extend exactly parallel to the molded tubes.
An essential prerequisite for this is that the cutting knives and their counter element can be separated from each other and kept apart until the lead length is at least as far as the ends of the shaped tube. Only then is the cutting device brought into effect by moving it together and the packaging material web is conveyed on until the beginning of the cut is at or somewhat behind the ends of the shaped tube. Since packaging material strips are now present in the area of the packaging material molding elements, the molding elements can be applied to the molding tubes by molding the strips, in which position these, as before, also, remain until the respective packaging material web supply roll is used up.
the method according to the invention and the associated device are intended in particular for tubular bag packs of small width and those which are longitudinally sealed with an inner sealing strip in the region of their packaging material edges.
an inner sealing strip in the region of their packaging material edges.
the method and device there is nothing to prevent the method and device from being used even if the tubular bags to be produced should have larger widths, as mentioned above, and also if the longitudinal seam sealing is carried out in a manner other than with an inserted inner sealing strip, that is to say overlapping, for example Striped edges.
the device for carrying out the method consists, as hitherto, of packaging material web guide elements 2 arranged on a device frame 1, a strip cutting device 3 with molded tubes 4 arranged behind one another in series, each with a strip width, corresponding to the width of the strip, and with which the packaging material molded elements can be placed on both sides of the cylindrical molded tubes 4 6 are assigned, a longitudinal cutting device 8 being arranged behind these longitudinal sealing tools 7 in the conveying direction and behind the shaped tube ends 4 ', which is followed by a transverse sealing tool 9 which can be moved up and down.
1 shows a device in which a sealing strip SS is guided from the other side and guided by a guide element 2 'to the respective shaped tube 4 in order to seal longitudinally sealed strip edges SR.
the elements of the cutting device 3 involved in the strip cut are designed such that they can be separated relative to one another with respect to the pass plane E of the packaging material web P and that the elements 6 'which directly and centrally capture the strips S of the packaging material molding elements 6 Molded tube diameter corresponding to semi-cylindrical molded surface F and the elements 6 '' corresponding to the strip edges SR detecting quarter-cylindrical molded surface F 'and these two elements 6' 'are coupled to actuators SG such that their abutment on the strip edges SR and the molded tube 4 with already applied semi-cylindrical molding surface F takes place.
the elements involved in the strip cut are formed from paired circular cutting knives 10 with reference to FIG. 4A.
FIG. 4B all circular cutting knives 10 sit together on shafts 11, which are supported on both sides on linkages 12 that are adjustable like scissors.
the actuating means and drives for the actuation of one or the other shaft 11 are not particularly shown, since there are various constructive possibilities for this, it being pointed out that the scissor-like assignment of the linkages 12 is advantageous but not mandatory.
FIGS. 5A, B With regard to the design of the packaging material molding elements, reference is made to FIGS. 5A, B.
the dashed lines indicate how the relevant strip is from this element 6' on Shaped tube 4 is deformed or applied to this.
These elements 6 ' all sit together on a carrier T which is vertically adjustable back and forth against the plane of passage of the packaging material web or the packaging material strip.
the counter elements for forming the strip edges SR are illustrated as an exemplary embodiment in FIG. 5B.
the quarter-cylindrical shaped surfaces F ' are designed as shells which are pivotably mounted on both sides at the height of the molded tube axis 4''. These shells, too, are seated on back and forth movable supports which, for example, can be constructed in a computational manner for all shells. These shells are moved to the strip edges SR (see FIG. 5A) with the opening position shown in dashed lines and closed by means of an actuating linkage SG, the strip edges SR being applied to the shaped tubes 4.
the quarter-cylindrical contact surfaces F ' can, however, also be parts of block-like elements in the sense of FIG.
strip edges SR are not butted but are to be sealed longitudinally overlapping, they are designed to remain in the embodiment according to FIG. 5B in the sense of FIG. 5C, that is, on the side of the strip edge to be placed SR the shell is somewhat shorter in its arc length and the other is held somewhat longer for the overlapping strip edge SR, the closure or application of this longer shell having to lag somewhat.
the cutting blades 10 of the strip cutting device 3 are opened in preparation for the machine for continuous running, as are the shaping elements 6 ', 6' 'and also the transverse sealing tool 9 with its sealing jaw, so that the packaging material web is uncut and is guided over the guide 2 until something can be pulled under the transverse sealing tool 9.
the closing and starting of the cutting device 3 is coupled, and the packaging material web, now cut into strips S, is retightened until the beginning of the cut is under the shaped tube ends 4 '.
the packaging material molding elements 6, namely the elements 6 'first are placed against the shaped tubes 4 while deforming the strips according to FIG.
a cross-cutting device 8 is arranged which cuts off the packaging tube strand formed directly below the cross-sealing seam formed, ie, in this case there are cross-sealed and open ends at other ends Packaging material tubes for further processing, ie filling and closing.
