The invention relates to a device for exchanging a numbering and imprinting device provided with a numbering shaft for receiving numbering units with an associated inking unit in printing machines for one on another Numbering shaft mounted other numbering and imprinting device by means of a about a horizontal pivoting device that can be pivoted parallel to the axis of the numbering shaft

It is known, for example, to use sheet-fed offset printing machines in special designs with a Equip numbering station so that the machine can be used not only for printing, but also for combined printing and numbering jobs. One ο such a numbering station consists of one that can be coupled to the drive of the machine Numbering shaft with seat rings on which one or more numbering machines depending on Print job can be mounted. The digits of the numbering units are colored by a numbering inking unit assigned to them, while the numbers are incremented via switching curves.

The numbering shaft is equipped with the individual numbering machines usually outside the machine. The entire numbering station must therefore be switched off the machine, or the numbering shaft is in the Machine asu equipped or preset, which usually means a longer masthead standstill. For the purpose of better handling, numbers are usually used rierwellö and numbering inking unit separately from each other out of the machine acceptable (DE-PS 22 21 3 * 3).

fell vttradvtadenen numbering orders such as the printing of checks, for what QbUdterweise special ecprint machines are used, can with the Iftwifewertt of the machine the personal data like name, address etc., in the Scheefclorimulare are imprinted »while with the downstream numbering machine the variable numbered hatchback numbers are applied. There Seheckeindrueke are often only required in very low support heights is a _ Constant changing of the numbering data required within shorter periods of time.

In order to avoid the resulting longer machine downtimes, the

Checkfucker usually with two numbering waves, one of which is at Edition pressure is in the machine, while the second wave is pre-set outside the machine for the (lactase application) in the meantime.

So special check printing machines are known in which the numbering station already consists of two numbering waves, which look alternately in the working position in the Machine or in the presetting position in front of the machine.

In one application, the two shafts are each supported by only one axle journal on a common support arm Storage of this support arm in the middle of the same on a horizontal bearing axis takes place, which is rotatable on at least one side wall of the machine and around a a certain amount can be extracted from this. To change the numbering shaft, the two shafts are pulled out from the side of the machine frame and, to IS ^ * rotated, reinstalled (US-PS 3,728,960). A comparable procedure can also be found in machine tool construction for changing tools their brackets.

Another known type of application is the pivoting out of a double-shaft storage system that accommodates both numbering machines from the machine by a horizon " tale axis, with the double-shaft bearing for the two numbering shafts as well rotated 180 * and swiveled back into the machine. For this purpose a, pivotable about an axis of rotation running parallel to the numbering shaft axis Swivel device. (A.B. Dick)

Both of the above-mentioned design variants have the serious disadvantage that the presetting position of the 2WeI ¹ Mn numbering shaft is extremely unfavorable because the machine operator must also work, for example, on the main printing unit or on other units located in this frontal area of the machine from this point on the machine and the printed sheets must also be observed when they are placed on the delivery pile »

On this basis, it is the object of the present invention to provide a device for exchanging numbering and imprinting devices in which the The second numbering shaft intended for presetting is located at a presetting station suitable for this purpose outside the operating and monitoring area of the machine units.

According to the invention, the task at hand is achieved by a device according to
