DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
The invention relates to soundproofing for a machine.
DESCRIPTION OF THE PRIOR ART
It is known from DE-Gm 90 07 329.0 to arrange sound-absorbing separating walls vertically between two adjoining print units, or between a print unit and a folding device, and to orient these walls with their sound absorbing means toward the above mentioned sound emission sources.
It is disadvantageous in connection with these protective devices that it is necessary to dismantle the sound-proofing device in an awkward manner for the purpose of maintenance and adjustment work.
FR-A-2359271 describes doors for the cargo space of a semi-trailer. These doors can be selectively pivoted around a right or left pivot axis.
SUMMARY OF THE INVENTION
The invention is based on the object of creating soundproofing for a machine or parts of a machine, which allows easy access.
In accordance with the invention this object is attained by the provision of soundproofing for a rotary printing press. This soundproofing has at least one door with a lining of a soundproofing material. This door has both left and right vertical pivot axes and can be selectively pivoted about either one of these two axes.
The advantages which can be attained by means of the present invention consist in particular in that, because of its division, the protective device for protection against sound and contact can be quickly removed without additional aids by one person for performing maintenance, adjustment and repair work. In the process it is only necessary, following the required insertion or removal of hinge bolts, to pivot the respective parts of the soundproofing around one of their longitudinal axes in order to make a part of the contact protection, behind which the corresponding components are located, accessible and to subsequently dismantle it. Possibly only the cover of a control opening needs to be removed. Because of the pivotability of the doors, a necessary access width is assured.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the invention is represented in the drawings and will be described in more detail in what follows.
Shown are in:
FIG. 1, a front view of a protective device in accordance with the present invention with partially opened portions of the soundproofing, and with a view of the portions of the contact protection plate disposed behind the soundproofing on a folding device of a web-fed rotary printing press, for example,
FIG. 2, a representation analogous to FIG. 1, but with the contact protection plate partially opened and with a view of the gear elements of the folding device,
FIG. 3, a front view of the protective device with closed soundproofing and a representation, by means of dashed lines, of the elements of the contact protection plate located behind the soundproofing, with a representation, by means of dashed lines, of fastening strips as well as the moldings of the lateral frames,
FIG. 4, a section IV - IV in accordance with FIG. 1, with an enlarged representation of the hinge arrangement of the doors of the soundproofing on the lateral frame,
FIG. 5, a section V--V in accordance with FIG. 1, with an enlarged representation of a cross section of the protective device as well as of the lateral frame with the gear chamber.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A protective device 1 for covering, for example, a gear chamber 3 located in a lateral frame 2, as seen in FIG. 5, in a folding device of a rotary printing press, is shown generally in FIG. 1, and consists of a multi-piece contact protection plate, identified as a whole by 4, and a multi-piece soundproofing door, identified as a whole by 6, which can be handled independently of the contact protection plate 4. The reference arrows for the plates 4, and for the doors 6 in this case respectively point to only one part of the plate 4 or the doors 6, as show in FIG. 1. The protection plate 4 consists of several mainly rectangular plate elements 9, 10, 11, 12, 13 of equal width "b," as seen in FIG. 2, and a right element 1
