Definitions

  • the invention relates to a belt section for transporting and slowing down folding products between two successive stations of a folding apparatus, in particular between a folding jaw cylinder and a longitudinal folding device or a delivery station, with at least two successive sections driven at mutually graded speeds, each consisting of an upper and a lower one
  • Belt sets each with a plurality of parallel belts and in each case at least one belt roller at the front in the transport direction and one belt roller at the rear in the transport direction, of which at least one of the belt rollers at the front in the transport direction of the section running at the rear, which runs faster in the transport direction, is height-adjustable.
  • the sections driven at mutually graded speeds can be pushed into one another in a prong-like manner such that the distance between the overlapping belt rollers on both sides of the belt section differs, preferably in the area of the upper belt set than in the area of the lower belt set .
  • These measures advantageously result in a mutual displacement of the belt rollers, so that the elasticity of the belt guide is retained over its entire length despite the overlap of its sections according to the invention.
  • the front belt roll of the rear section provided on the side of the larger belt roll spacing can expediently be adjustable in height. This measure advantageously results in a relatively long wedge between the adjacent, spaced-apart band rollers and thus enables the delay and transfer of the products to be adjusted very gently.
  • the smaller belt roll spacing can suitably correspond approximately to the maximum product length to be processed.
  • the height adjustable ge stored front belt roll of the rear section adjacent rear belt roll of the front section also adjustable in height, preferably pivotally mounted about the same axis. This measure enables the delays to be fine-tuned even further and the transfer to be carried out smoothly.
  • the use of a shaft advantageously allows a high degree of structural freedom, since in this case the rollers that hold the tapes can penetrate between two cams to form a kink.
  • these cams can each be designed as radially protruding fingers of disks arranged on the continuous shaft and set in a gap with respect to the belts.
  • Another useful measure can be that the peripheral speed of the cams is slightly reduced compared to the transport speed of the associated front section, which results in a secure stop.
  • the drawing contains a schematic representation of a tape guide according to the invention with two nested sections.
  • the belt section shown in the drawing can be arranged downstream of a folding jaw cylinder of a folding apparatus (not shown in more detail) and lead to a bucket wheel of a delivery station (also not shown in more detail) or under a folding sword to produce a third fold.
  • the direction of transport is indicated by the arrow R.
  • the basic structure and the mode of operation of a folder or the elements of a folder outlined above are known per se and therefore require no further explanation.
  • the transport speed of the rear section 1 in the transport direction corresponds to the working speed of the upstream organ, here the peripheral speed of the upstream folding jaw cylinder.
  • the speed of the further section 2 of the belt section shown should be graduated compared to this speed of section 1, which results in a 50% delay in the products to be transported.
  • the element acted upon by the illustrated belt section here the paddle wheel of the delivery station or the sword folding mechanism, can therefore advantageously run at a speed which is reduced by half compared to the working speed of the jaw cylinder, which is very desirable.
  • the product stream length is shortened in accordance with the ratio of the speed gradation between sections 1 and 2. There must therefore be sufficient gaps between the individual, undelayed products.
  • collective production in which every second product is missing, a 50% reduction and therefore a 50% product delay is possible, even if only one belt section is available.
  • two or more belt sections, which are acted upon alternatively must be provided in order to generate corresponding gaps between two successive products. Based on simple production without gaps between two successive products, the number of belt sections required results from the fact that this corresponds to the reciprocal work of the ratio of the speed between the first and the last section of a belt section.
  • Sections 1 and 2 of the belt section each consist of an upper and a lower belt set, which in turn consist of a plurality of parallel endless belts 3, which are arranged next to one another at a distance.
  • the distance between two adjacent bands should at least correspond to the bandwidth.
  • the belts 3 of the upper and the respectively associated lower belt set are placed against one another in such a way that the products that come between them are transported in the direction of the arrow R.
  • the course of the belts 3 is defined by belt rollers, of which, in the present context, the belt rollers at the front, designated by 4, of the rear section 1 in the transport direction and the belt rollers at the rear, designated 5 in the transport direction, of the front section 2, are of importance in the present context .
  • Sections 1 and 2 are not spaced one behind the other in the joint area, but are pushed together like tines.
  • the bands 3 of the front section 2 engage in the gaps formed by the band gap between the bands 3 of the rear section 1 and vice versa.
  • the strips 3 of sections 1 and 2 are accordingly set to a gap, that is to say they are arranged at least laterally offset from one another by the respective strip width, which results in the galvanizing mentioned.
  • the sections 1 and 2 are expediently pushed into one another so far that the rear belt rollers 5 of the front section 2 are encompassed by the loop formed by the belts 3 running around the front belt rollers 4 of the rear section 1 and vice versa. This he possible to use continuous rollers in an advantageous manner.
  • the above measures advantageously result in a practically seamless transition from sections 1 and 2, which no longer has any protruding edges, which not only has a gentle effect on the products to be transported, but also proves to be extremely easy to maintain.
  • the associated upper and lower belt rollers 4 and 5 are advantageously not arranged opposite each other, but offset in the direction of transport, which results in a high elasticity of the belt section, so that differently strong products can be transported in an advantageous manner without significant adjustment work.
  • the respectively adjacent upper and lower belt rolls 4, 5 are offset from one another in such a way that there is a greater roll spacing in the area of the upper belt sets of the belt section than in the area of the lower belt sets of the belt section.
  • the distance between the two lower belt rolls 4, 5 suitably corresponds approximately to the maximum product length that can be processed on the upstream folding jaw cylinder, which results in a reliable intervention.
  • the height provided on the side of the larger belt roll spacing, in this case the front upper belt roll 4 in the transport direction, of the rear section 1 in the transport direction is adjustable .
  • this is accomplished by means of a swivel arm 7 which receives the band roller 4 and is pivotably mounted about the axis 6. All other belt rollers can be mounted practically unadjustable.
  • an outlet wedge can be set in the region of the rear section 1 of the belt section in the transport direction, the tip of which practically forms the rear belt roll 5 of the front section 2 adjacent to the height-adjustable roll 4.
  • the products to be transported can be transferred smoothly from one section to the next section running at a lower speed.
  • the rear upper belt roller 5 of the front section 2 in the direction of transport is also mounted in a height-adjustable manner in the exemplary embodiment shown, which is likewise accomplished here by means of a swivel arm 7 which can be pivoted about the axis 6.
  • the axis 6 is located in the middle between the two rollers 4 and 5, so that the swivel arms 7 are of approximately the same length.
  • swivel-mounted belt rollers can also be provided, as indicated at 8.
  • the transfer area formed by the mutual overlap of sections 1 and 2 is followed by a start stop designated as a whole by 9, the stop edge 10 of which intersects the transport path of the belts 3 of the front section 2 in the transport direction .
  • the start stop 9 consists of a continuous shaft 11, onto which disks 12 are placed at a distance from the gaps between the bands 3 of the section 2, which in turn form one or more fingers projecting in the radial direction to form a start edge 10, which fingers extend between the Reach bands 3 through. These fingers of adjacent disks 12 are aligned so that the desired stop results. At the same time, the products approaching the leading edge 10 experience an alignment, if this is necessary.
  • the peripheral speed of the leading edge 10 is slightly reduced, approximately by 1-2%, compared to the transport speed of the section 2, which results in a reliable stop of the products.
  • the speed of the start stop 9 can expediently be adjustable, which enables an individual adaptation to the circumstances of the individual case.
  • the use of disks 12 placed on a continuous shaft 11 advantageously allows a very compact design.
  • other elements can advantageously be arranged between the disks 12, as is indicated in the exemplary embodiment shown with the aid of the belt rollers 13, by means of which the belts 3 of the transport direction of the front section 2 are deflected such that there is an overlap of the sections 1 and 2 about the same band directions, d.
  • opaque transport levels result in what is important for a smooth, seamless handover of the products.
  • the tape rolls 13 can expediently be mounted individually on tabs which engage between the disks 12 and are not shown in detail here, preferably pivotably mounted and are adjustable in their pivoting position.
  • the belt section described above comprises only two sections, the speeds of which are graded by 50% against one another. However, it would also be conceivable to arrange a plurality of such belt sections with corresponding overlaps one behind the other, with an even greater overall speed reduction being achieved with a smaller individual gradation of the speed.
