DESCRIPTION:
BRIEF SUMMARY
SPECIFICATION
The invention relates to a packaging device for reels of magnetic tape.
BACKGROUND ART
Magnetic tape reels that usually exhibit a diameter of up to approximately 40 cm and comprise a plurality of precisely stacked tape windings are called pancakes. These pancakes represent with respect to their fabrication and the kind of the materials used a cost intensive intermediate product, which must be transported over sometimes very far distances from the manufacturer to the further processing operations. During such transport, however, it must be guaranteed that the pancakes wound with great precision do not warp due to excessive jolts or become damaged due to dirt. For this reason time-consuming packaging of the magnetic tape reels is necessary for safe transport.
Packaging devices that are suitable for receiving a single pancake are known, for example, from the prior art. These packaging devices are usually made of vibration- and impact-absorbing material, for example Styropor, so that the pancake is protected against dangerous vibrations and impact shock. Moreover, such a packaging material has the property that it deforms elastically upon impact and thus the energy that could result in the pancake being damaged is absorbed. The packaging design according to the prior art anticipates that the packaging will be intentionally deformed or even destroyed upon impact in order to protect its content and is designed consequently in principle as a disposable packaging. However, such a packaging creates in light of the required quantities a significant disposal problem; also high packaging costs or packaging material costs are associated with this method.
DISCLOSURE OF THE INVENTION
The invention is based on the problem of providing an inexpensive, reusable packaging device for safe transport of magnetic tape reels or socalled pancakes.
This problem with a packaging device of its class is solved by means of the present invention. The packaging volume for each pancake is drastically reduced by packing several pancakes into a collecting tank, thus reducing the packaging costs. Transfer of the outer vibrations to the collecting tank is damped by means of the force-absorbing positioning of the collecting tank within the support frame. In addition, forces acting from the outside are absorbed by the support frame, so that the collecting tank is not significantly deformed or even destroyed during normal transport operations. Thus, the packaging device can be reused multiple times.
By means of the embodiment of the present invention, shearing strains, which can result in small warping or small deformation of the collecting tank, are introduced predominantly into the rear-sided panel of the collecting tank when the support frame deforms slightly due to impact shock. Thereafter the entire packaging device remains functional for renewed use. Moreover, such a design of the packaging device allows the collecting tank to be cleaned in a simple manner.
Furthermore, it is advantageous that according to the present invention the receiving mechanisms for the pancakes within the collecting tank are designed as self-supporting mandrels with at least one longitudinal groove and a moveable stop and are freely accessible from a front side, since in this manner an automatic loading and unloading of the collecting tank and thus the introduction of the packaging device into the integrated flow of material is rendered possible in an inexpensive manner.
One embodiment according to the present invention allows a dust-free storage of the pancakes to be transported, so that thus the danger of damage by means of soiling is virtually eliminated.
