1. Field of the Invention
The invention relates to a buckle folding machine having two side walls arranged at a distance from each other, between which at least one lower folding pocket is arranged.
2. Description of the Background Art
DE 32 17 711 C1 discloses a buckle folding machine whose folding pockets can be displaced, together or individually, in their longitudinal direction in order to permit adjustment of the folding pockets, the removal of blade shafts, or the insertion of sheet deflectors. The displacement is carried out via a shaft running at right angles to the long sides of the folding pockets, on which gears are arranged which can be engaged in a tooth profile on the long side of the folding pockets.
Even though the folding pockets can be displaced in their longitudinal direction, the access to the region of the folding rolls is restricted, so that an operator has to go under the buckle folding machine in order to carry out the adjustment work. The adjustment work is therefore awkward and time-consuming.
The invention is based on the object of using constructionally simple means to provide a buckle folding machine which makes it possible to carry out adjustment work in the region of the folding rolls quickly and simply.
This object is achieved by a buckle folding machine comprising an operator facing side wall and a side wall remote from an operator, said side walls being arranged at a distance from each other and at least one lower folding pocket being arranged between said side walls, wherein said lower folding pocket is guided in a cassette for displacement from an operating position, in which it adjoins folding rolls, into a release position, in which it is located at a distance from said folding rolls, wherein said lower folding pocket is located outside a coverage of said operator facing side wall when in said release position, and wherein said cassette is guided such that it can be displaced, perpendicular to said operator facing side wall, from an inserted position, in which said lower folding pocket is located within said buckle folding machine, into a withdrawn position, in which said lower folding pocket is located outside said buckle folding machine.
The design of the buckle folding machine according to the invention makes it possible to move the lower folding pockets out of the region of the buckle folding machine, so that the region of the folding rolls is freely accessible. This makes it possible to carry out adjustment work in a simple manner, such as the adjustment of the folding pockets or the fitting of sheet deflectors.
The lower folding pocket can preferably be moved from the operating position into the release position and back by means of a pneumatic device. A telescopic guide is preferably used for the lateral displacement of the cassette. The telescopic guide comprises two three-part telescopic rods, for example.
An exemplary embodiment of the invention will be explained in more detail below by using the drawings, in which:

As the side views of
The displacement of the folding pockets 22, 24 in their longitudinal direction can be effected by a pneumatic device.
The cassette 28 is in turn guided by three-part telescopic rods 32, which extend at right angles to the side walls 14, 16 of the buckle folding machine 10, adjacent to the right-hand edge of the lower leg 15. The telescopic rods 32 are fixed by one end to the sidewalls 16, go through the side plate 34 of the cassette 28 and are connected by the other end to the side plate 30.
In
In order that it is possible to carry out adjustment work or other work in the region of the folding rolls 26, the lower folding pockets 22, 24 can be moved out in their longitudinal direction by means of the pneumatic device, as indicated in
