Definitions
- Synchronous adjustable tubular bag forming device Synchronous adjustable tubular bag forming device
- the invention relates to a
- Tubular bag forming device for forming a
- Hose from a material web for forming, filling and sealing machines, with an adjustment device.
- Packaging machines which are also known as tubular bag machines or forming, filling and sealing machines, are used to form a flat, flexible material web into a tube. Depending on the direction of the
- Material web in the forming process differentiates between vertical and horizontal tubular bag machines.
- Material web is first curved, and a prism part, on which the curved cross section is formed into a closed tube cross section.
- Forming devices are called form shoulders.
- Shaped shoulders for one and the same tubular bag machine is disadvantageous with this solution that longer downtimes are inevitable when changing the format in order to replace the shaped shoulder, realigning deflection rollers for the material web, etc.
- An object of the invention is to improve
- Specifying shaping devices for tubular bag machines which are adjustable in a manner that an adaptation to changing in a relatively simple manner
- Hose cross sections can be made without the
- a shaping device for forming a hose from a material web is proposed with a first forming area in which the material web is guided from a web inlet straight line to a forming edge and is thereby formed from a flat to a curved state, and one downstream of the first Forming area adjoining second forming area, in which the material web is guided from the forming edge to a web outlet cross-section and is thereby deformed from the curved to a tubular state, which comprises the following: a base frame, two on the base frame
- Forming elements arranged next to one another and slanted relative to the transport direction of the material web, each with a segment of the forming edge, and a seam former for forming, arranged in the region of the web outlet cross section a longitudinal seam in the material web, and a
- Adjustment device that acts synchronously on both shaping elements to change the hose cross section to be produced.
- the adjusting device can comprise, for example, one or more servo motors which act on the shaping elements in order to close them
- the shaping elements each comprise a first partial element and a second partial element, the second partial element abutting the first partial element in a minimum position and the second partial element forming a gap in the forming edge that increases with increasing distance from the first partial element is adjustable to a maximum position, and the adjustment device for changing the
- Hose cross section to be produced also acts synchronously on both second sub-elements.
- the adjusting device for each shaping element comprises an elastic traction means, one end of which is connected to a front end of a shaping element and the other end of which is connected to a rear end of a
- Forming element is connected. That way they can Forming elements on the base plate so back and forth
- Shaping elements are moved back and forth along an adjustment path that runs obliquely to the transport direction of the packages. It is still advantageous
- the traction means is guided by an arrangement of deflection rollers so that the traction means even when the traction means moves the
- Forming element always remains taut.
- the adjustment device for each shaping element
- Shaping elements are arranged on a slide plate, which is displaceable on the base plate in the horizontal plane. In this way, all elements of the
- Sliding plate can be summarized.
- a side guide for laterally guiding the packages is arranged in front of and behind each shaping element
- Transport path of the package-extending adjustment path is shifted with.
- the side guides can advantageously be formed at least partially by the ends of the traction means. For example, on the respective slide plate in front of and behind the
- a fastener for the traction means can be attached, to which the respective end of the
- Traction means is attached so that the front and rear section of the traction means, insofar as these run parallel to the transport path of the packages, simultaneously serve as length-adjustable side guides for the packages.
- the side guides each overlap two
- Forming area i.e. the rear end of the shaping element, to the rear edge of the base plate.
- Traction means are formed, the associated overlapping side guide element, for example by a lateral Housing wall one movable with the molding element
- Housing can be formed.
- Lateral guide elements for example by a side housing wall of a movable with the forming element
- Housing and a side housing wall of an additional housing movable only transversely but not longitudinally to the transport direction of the packages.
- Fig. 1 shows a basic structure of an adjustable
- Fig. 1 is a patent pending at the same time
- Hose cross section is adjustable in two dimensions, so that both the width and the depth of the
- Tubular cross-section can be varied.
- a plate-shaped base frame 2 forms the basis of the device, on which packages 4 are moved in a transport direction, while a material web 1 passes through
- the base frame 2 has slots 21 which serve to bring the side edges of the material web with progressive deformation under the base frame 2, where these side edges are placed one above the other by a seam former 22 arranged on the underside of the base frame 2, so that a fin seam is formed, which then (by a here not shown
- Welding device can be welded, which completes the formation of a packaging tube.
- the shaping elements are designed symmetrically to one another in a manner similar to known devices and by means of an adjustment guide element 33, which is slot-shaped (not shown here)
- the direction of transport of the packages 4 and the material web 1 is displaceable and can be locked at any position, the adjustment tracks being V-shaped and the seam former 22 being arranged at the apex of the V-shaped arrangement of the adjustment tracks.
- the two shaping elements 3 each enter
- Forming edge segment i.e. the forming edge 12 is not formed in one piece. Due to the proposed further subdivision of the shaping elements 3 into a first partial element 31 and a second partial element 32, which is carried by the first partial element 31, the forming edge segments 12 are also divided again, i.e. each of the two shaping elements 3 contains two subsegments of the shaping edge 12.
- the V-shaped adjustability of the two shaping elements 3 relative to the base frame 2 enables the width of the web outlet cross section 13 to be increased, as in the case of known devices vary .
- the proposed device makes it possible to vary the height of the web outlet cross section 13.
- the second sub-element 32 is held on the first sub-element 31 by a telescopic rod 34, which enables the second sub-element to be steplessly adjusted, namely between a minimum position in which the second sub-element 32 touches the first sub-element 31, so that the two sub-segments the forming edge 12
- Bridging element 35 which is a flexible stainless steel wire in the exemplary embodiment, which is attached to the second partial element 32 and is pulled with the movement of the second partial element 32 away from the first partial element 31 from a guide that the first partial element 31 for
- Bridging element at any point by means of a locking element 36, which is realized in the exemplary embodiment by a screw.
- 2 to 5 show improvements to a first embodiment of this shaping device on the one hand, allow the shaping elements 3 to be adjusted synchronously and, on the other hand, thus make the setting possible to be automated.
- 2 and 3 show a first set-up state of the molding device in two
- 4 and 5 show a second set-up state of the molding device in two different views.
- the shaping device has an adjusting device which has an elastic one for each shaping element 3
- Traction means 51 for example a toothed belt or
- the traction means is driven by a drive roller 52, which in turn does not have one here
- the traction means 51 is guided through an arrangement of deflection rollers 53 such that the traction means 51 also through the traction means 51
- Some deflection rollers 53 are arranged on the base plate 2 so that they are perpendicular to
- the shaping elements 3 and some other deflection rollers 53 are each arranged on a sliding plate 54, which is on the base plate 2 in the
- Material path extending adjustment path of the shaping elements 3, is displaceable, which also means that on the
- Shaping elements 3 are moved when the Forming device is reset.
- the two drive rollers 52 can, for example, either with a common or with their own
- Drive roller 52 connected, for example by gears or a belt drive, for example on the
- Bottom of the base frame 2 is arranged.
- the front and rear ends of the two traction means 51 form side guides 23 for the packages 4 on their way through the forming area of the shaping device, in which the packages 4 are enclosed by the tube cross section that is formed.
- the front end of the traction mechanism 51 is fastened to the sliding plate 54 in the immediate vicinity of the front end of the shaping element 3. From this fastening point to the first deflection roller 53 (which can only be moved transversely to the transport direction) on the front edge of the base plate 2, the traction means 51 forms a front side guide 23 for the packages 4. If the shaping element (at an angle to the transport direction)
- the rear end of the traction means 51 is in the immediate vicinity of the rear end of the shaping element 3 on the sliding plate 54 attached. From the last deflection roller 53 (only movable transversely to the transport direction) on the rear edge of the base plate 2 up to this fastening point, the traction means 51 forms a rear side guide 23 for the
- the length of the rear side guide 23 changes and at the same time it moves with the last deflecting roller 53 transversely to the transport direction. Together, the change in length and the transverse movement of the side guide 23 ensure that it always has the required length and is in the correct position.
- the side guides 23 always extend regardless of the current position of the shaping elements 3, 31, 32, 33 from the front edge of the base plate 2 to the entry into the forming area, i.e. the front end of the forming element 3, 31, 32, 33, as well as from the outlet from the forming area, i.e. the rear end of the shaping element 3, 31, 32, 33, to the rear edge of the base plate 2.
- the overlapping side guide elements 23a, 23b are formed by lateral housing walls of a housing 61 which is movable with the shaping element 3, 31, 32, 33 and an additional housing 62 which is movable only transversely but not longitudinally to the transport direction of the packages 4.
