Description

The present invention relates to a switching arrangement for controlling the individual devices movable with respect to an associated bookbinding machine, in particular the supercharger movable on a collecting machine and the transfer device. As is known per se, the known collecting machines or other bookbinding machines have a multiplicity of stacking stations or compartments. These known collecting machines require an equal number of loaders, the same being the signatures to be stacked, folded sheets or the like. deliver. Depending on the format of the signatures to be stacked or the like, it is therefore necessary to position or regulate each loader in relation to the collecting machine or the like. Up to now, this positioning has been carried out manually by shifting each loader onto its steering or carrying wheels, i.e. each supercharger was manually pushed on the floor in any direction in the manner of a chassis.

The applicant has proposed a supercharger (Italian patent application no. 22806 A / 79, filed on May 18, 1979), in which an upper supporting frame is provided, which the supply and the

Lifting straps and the transfer device carries and is mounted on a base on wheels. In one embodiment, these rolling means consist of wheels, preferably ball bearings, the latter being mounted on a support frame and drive means being provided which cause the displacement or movement of these superchargers or the upper support frames thereof. The present invention has for its object to provide a switching arrangement for controlling the individual superchargers, the proposed switching arrangement being able to drastically reduce the times required for shifting or regulating the individual superchargers when changing the format of the signatures, folded sheets or the like belittling.

In the case of the supercharger proposed by the applicant, the transfer device provided with disks or transfer cords, which cooperates with the supercharger lifting belts, is also advantageously provided in a remotely controllable manner, and the switching arrangement according to the invention which is now proposed can also be used to control the transfer devices just mentioned.

In addition to the advantage of a drastic reduction in the regulation or equipment times of the bookbinding machine, the solution according to the invention also achieves the further advantage with regard to minimal labor expenditure. Another advantage that can be achieved with the switching arrangement according to the invention is that the entire intended superchargers, or the entire proposed transfer devices of the signatures or the like, are positioned correctly and at the same time, or in succession.

The object on which the present invention is based is characterized by a switching arrangement for controlling the individual devices movable in relation to an associated bookbinding machine, in particular the supercharger movable on a collecting machine and the transfer device, characterized in that a device which drives or returns the devices Selector switch is provided, which is parallel to the control devices assigned to the drives, in order to bring about a feed or a return of the devices by the same amount. According to a first variant, the switching arrangement according to the invention is characterized in that in the parallel connection of the control devices assigned to the drives mentioned, a reference element is provided for each device, which comprises an active part and a corresponding passive part cooperating with it, the reference element being capable of to interrupt directly or indirectly the power supply of the assigned drive when the active part of a reference element is in precise alignment with respect to the respective passive part of the reference element which cooperates with it.

Further developments and variants of the switching arrangement according to the invention can also be found in the subclaims. Further features, advantages and details of the switching arrangement according to the invention can be clearly seen from the following description, which relates to the switching arrangement according to the invention and to a variant thereof, the specified embodiments being shown only by way of example and not in a restrictive manner in the drawing shown.

on which can be shifted e.g. cooperates with a spindle, not shown.

In the switching arrangement according to the invention from FIG. 2, the motors 3 are supplied with current in parallel, a known remote switch 4 or the like being provided in series with each motor 3, these remote switches being connected in parallel and a selector switch 5 in their supply circuit o. Like. Contain, the latter makes it possible to effect the desired direction of rotation of the motors 3 clockwise or counterclockwise via the remote switch 4 mentioned.

For the sake of simplicity, the representation of the switches and other conventional components has been omitted in the switching arrangement because they are already known per se and are readily accessible to the person skilled in the art.

In the switching arrangement shown, it is possible to actuate the selector switch 5 to effect the simultaneous rotation of the motors 3 with subsequent subsequent displacement of the superchargers 2 in one or the other direction and for exactly the same amount.

This embodiment is particularly simple and reliable. In the circuit arrangement shown in FIG. 3, the active part 6 of a retroreflective photocell, the passive part 7 of which is attached to the adjacent charger 2, is inserted in the circuit of each charger 2. The circuit is designed such that after the first regulation carried out in the first supercharger 2 or in a master or control cell, the supply circuit of the remote switch 4 or the like is switched on, as a result of which the excitation of the motor of each supercharger takes place until the active part 6 of the associated photocell arrives in precise alignment with respect to the interacting passive part 2. The passive part 2 itself is advantageously provided as a retroreflective element. The direction of rotation of the motors 3 is similarly determined via a selector switch provided in the first supercharger 2 or in the master or control cell. There is thus a subsequent and automatic control of the supercharger 2, namely from the first supercharger 2 against the last one on the right side of the drawing. Although the switching arrangements shown have a great simplicity in terms of design and functionality, they make it possible to easily achieve the stated object and achieve the advantages mentioned.

In the illustration of FIG. 1, a switching arrangement as shown in FIG. 3 is provided, 8 being a master or control cell or a control cabinet. In Fig. 1, the first three and the dashed line supercharger 2 s are already positioned, the two remaining superchargers 2 still being set to the older or earlier format.

The switching arrangements according to the invention which are shown and provided for the displacement of the superchargers can likewise advantageously be used for controlling the transfer devices which interact with the supercharger lifting belts and are provided with rope pulleys or guide cords. The rope pulleys and guide cords serve to guide the movement of the transfer device, the direction of movement being determined by the selector switch and the amount of movement by the circuit arrangement according to the invention.

It is emphasized that the active part of the reference element or the passive part thereof can each be provided on the adjacent supercharger, or it is also possible to have a single active part or a passive part on a stationary part, e.g. 20 to be provided on the master or control cell in a controllable or movable manner, the active part or the passive part serving for the entire intended supercharger.

If pneumatic or hydraulic busbars e.g. Piston-cylinder units are provided as drives, the remote switches can be replaced with drives known per se as control devices. The use of the photocells can then be easily maintained.

As already mentioned, it is advantageous to also use the switching arrangement according to the invention for the transfer devices provided with disks or guide cords. In this way, a perfect, quick and accurate remote control of the entire individual charger 2 is achieved. All the features that can be inferred from the description, the claims and the attached drawing are considered to be essential to the invention both individually and in any combination with one another.

Although the above description relates to the superchargers assigned to a collecting machine, it goes without saying that the switching arrangement according to the invention can also be easily used with other bookbinding machines which correspond to similar requirements.
