Definitions

  • Transport device for the removal of film rolls from a film winding machine
  • the present invention relates to a transport device for the removal of film rolls from a film winding machine and to a method for the operation of a transport device formed in this way.

  • a lifting table, z. B. at the end of a such inclined plane the rolled out rolls of film raises to a removal height.
  • a disadvantage of known transport devices is that a relatively high design effort must be operated. In addition, only a single roll of film from the film winding machine can always be removed, so that an acceleration or automation of removal is not possible or very difficult. Similarly, it is a disadvantage that an additional transport away from the film winding machine for z. B. an automatic drop station is necessary. This leads to a further increase in the complexity and the corresponding costs of such an entire film winding machine.
  • a transport device serves to remove film rolls from a film winding machine.
  • the transport device has an inlet section for the shrinkage of the film rolls in the transport device.
  • a conveyor belt with conveying means is provided for conveying the film rolls along the transport direction.

  • the inlet section as well as the laying section may preferably have their own transport devices.
  • there own conveyor belts may be provided to perform the running in or the drop.
  • inlet section and / or removal section likewise have an inclined plane with a negative gradient, that is to say with a gradient in the conveying direction.

  • the conveyor belt together with the bottom surface and the corresponding lifting height preferably form a right-angled triangle.
  • the depositing section is z. B. formed as a depositing table and serves to receive one or preferably more than one film roll. For two or more rolls of film z. B. by semi-automatic or automatic sampling systems, eg. B. robot systems, even two or more film rolls removed simultaneously from the depositing section become. This leads to a further improvement in the use of a transport device according to the invention.
  • the pitch angle which results from the translation distance and the lifting height, is preferably in the range of up to about 35 °. It is preferred if the corresponding pitch angle is formed in the range between approximately 10 ° and approximately 35 °.

  • the gradient angle in this range is preferably in the range between about 0.5 ° and about 5 °.
  • the gradient angle can be variably changed by an adjusting device.
  • Conveying means can be designed in many different ways. It is preferred if the conveying means have geometrical formations which allow a striking of the film rolls. The stop is provided so that the film rolls can not roll over the conveyor. Rather, the conveying means push the film rolls, so to speak, together with the conveyor belt in the transport direction.
  • the conveyor belt z. B. formed as a chain link conveyor belt.
  • the conveying means can accordingly be individual chain links. Accordingly, as it were, a one-piece or integral design of the conveyor with the conveyor belt.
  • a buffer effect can be generated. So z. B. of the film winding machine in a machine cycle at certain times in a defined time manner always provided a film roll. However, the removal from the depositing section may have a different tact, in particular per clocking step also remove two or more film rolls. Accordingly, a buffer can be made available by the transport device, which serves, so to speak, as a clock interface or compensation possibility between the different cycles of the removal and the film winding machine. Due to the correlation between translational distance and lifting height of this buffer is combined with an increase in the film rolls to a particular ergonomically advantageous lifting height.
  • the conveyor belt has a length at which at least two film rolls can be arranged on the conveyor belt at the same time. This leads to the improvement of the already described buffer effect.

  • the conveyor belt Located on the stowage section, z. B. by a semi-automatic or automatic removal device, after the direct removal of the film rolls no more film roll more, the conveyor belt can be operated with a Räumfunktion.
  • the conveyor belt is transported until the depositing section is completely filled again with film rolls.
  • individual conveyor positions can run empty on the conveyor belt and accordingly again provide free capacity on the conveyor belt for the next film rolls available.
  • the conveyor belt can also be operated counter to the transport direction, so that from below the conveyor belt is always completely filled with incoming film rolls becomes. It is therefore fundamentally possible to operate the conveyor belt in both directions, if this is necessary in particular with regard to maximizing the buffer function.

  • a stiffening angle may additionally have a stiffening rib. The stiffening takes place counter to the conveying direction, ie against kinking or folding of the conveyor against the conveying effect.
  • the conveying means have a conveying height which is in a functional relationship with the diameter of the film rolls to be conveyed and the pitch angle of the conveyor belt.
  • the conveyor height can be calculated explicitly in this way, depending on the current operational situation. The steeper a conveyor belt is formed, the larger the conveying means and their funding height must be formed. The larger the film rolls are in terms of their diameter, the larger the conveying means must be, in particular with regard to the conveying height.
  • the conveying effect is achieved in that there is sufficient support of the torque, which results from the weight of the film rolls and their point of application in the center of the film roll, relative to the support of the upper edge of the conveyor.

  • at least two conveying means are provided per conveying position, in order to be able to provide a substantially symmetrical support with higher security. The more conveying means are formed, the finer can also be formed corresponding inlet and Ablegekarmme which allow passage of the funding.
  • the depositing section has a geometric extension for depositing at least two film rolls. Accordingly, an increased buffering effect is also provided on the depositing section.
  • a combination with semi-automatic or fully automatic removal devices is possible in this way. So z. B. all provided on the depositing film rolls are simultaneously cleared by a robot arm.

  • a parking trough is provided in the inlet section, as will be explained in more detail below.
  • a Parkmulde is formed between the inlet section and the conveyor belt. This can be seen in particular as the lowest point of the transport device for a film roll. So runs z. B. by gravity, the film roll along the inlet section to this Parkmulde on a downgrade.
