  • the invention Device Due to the adjustable design of the shaft walls in the invention Device achieved various effects.
  • the invention Device with very little effort to different Width formats of the band-shaped material to be stored in the buffer be adjusted.
  • a defined, optimal dimensioned gap can be set, which is an exact dosage of the Overpressure section allows the amount of air flowing into the vacuum section. This can cause the tensile stress caused by the pressure difference on the band-shaped material optimally adapted to the given transport conditions so that the material takes on the desired free loop shape, without twisting or curling of the band-shaped material.
  • the device for generating the pressure difference has a blower with overpressure can be generated in the overpressure section.
  • the usage A blower has the advantage that in a comparatively simple way by blowing of air in the overpressure section an air cushion in the buffer can be formed, the band-shaped material in its free loop shape supports.
  • the air extraction is used together with the blower, it is also from Advantage if the air extraction through an air recirculation with the fan in Flow connection can be brought. That way you can Blowers and air extraction support each other in their funding, so that the total power required to generate a sufficient high pressure difference is minimized.
  • the distance between the shaft walls is set by appropriate Adjustment devices, such as set screws or the like.
  • an actuating device be added to the device to provide, which is a very quick change in the distance between the shaft walls.
  • the actuator can do this either manually adjusted or for automatic adjustment with an actuator, such as a pneumatic cylinder, a servomotor or the like his.
  • Embodiment of the device according to the invention at the buffer store two parallel spaced guides are provided, along which the band-shaped material at least with one of its flat sides is performed in sections.
  • the two guides are preferably each made of two guide profiles formed, one of the guide profiles on one shaft wall and the other of the guide profiles on the other shaft wall of the buffer store is attached and the two guide profiles of each guide interlock. Due to the previously described formation of the guides from two guide profiles each it is guaranteed that even with a relative adjustment of the Shaft walls to each other the band-shaped material in any position of the Shaft walls is supported by the guide profiles. A passage of air by minimizing the guides from the buffer store, it is also proposed to design the two leadership profiles of each leadership so that they interlock to form a labyrinth seal. Alternatively, the Appropriate lip seals can be used.
  • the intermediate store arranged so that the band-shaped material is under the action of gravity Formation of the loop shape in the buffer hangs.
  • a device 10 according to the invention is shown in perspective in FIG. 1 shown for the temporary storage of a developed, photographic film 12.
  • the device 10 has a shaft-shaped intermediate storage 14, which in Direction of transport of the film 12 seen between two workstations, for example a prescanner and a main scanner. While the operation of the workstations, the film 12 becomes high, constantly changing Transport speeds through the intermediate storage 14, wherein the length of the portion of the film recorded in the buffer 14 12 constantly changes.
  • FIG. 2 shows, in which a top view of the device 10 is shown, the Buffer 14 made of two parallel spaced apart Shaft walls 16 and 18 as well as two equally spaced, guides defining the side walls of the intermediate storage 14 20 and 22 formed.
  • the rear shaft wall 16 is fixed, while the front shaft wall 18 at a distance from the rear shaft wall 16 starting from one Starting position in which it is mechanically driven by a spring arrangement, not shown is biased against the biasing force of the spring assembly in parallel can be adjusted, as will be explained later.
  • the two guides 20 and 22 are each made of two guide profiles 24 and 26 are formed, the one guide profile 24 of each guide 20 and 22 is attached to the rear shaft wall 6, while the other guide profile 26 is held on the front, adjustable shaft wall 18.
  • the two Guide profiles 24 and 26 are designed in cross section so that they form a labyrinth seal 28 interlock.
  • FIG. 1 further shows, is near the upper open end of the buffer 14 an air injection opening 30 and near the lower end of the buffer 14 an air suction 32 is provided.
  • the air suction 32 is stopped through an air return 34 with a fan 60 in flow communication.
  • a flap not shown, the flow connection between the blower 60 and the air extraction 32 are interrupted, with the closed Flap the air extraction 32 is deactivated.
  • the Device 10 an adjusting device 36 for adjusting the front shaft wall 18 of the buffer memory 14 is provided, the structure of which is described below 1 and 2 will be explained in more detail.
  • the actuating device 36 has at the two ends of the intermediate storage 14 each have two eccentrics 38 and 40 on either side of the shaft-shaped intermediate storage 14 are arranged. Each on one side of the cache 14 arranged pair of eccentrics 38 and 40 is on a common Axis A and B held in rotation, which parallel to the longitudinal direction of the two Well walls 16 and 18 run.
  • the two axes A and B of the two pairs of eccentrics 38 and 40 are operatively connected to one another by a coupling rod 42.
  • the coupling rod 42 has one end at one end of a on the axis B rotatably held coupling lever 44 articulated.
