If, for example, the swivel arm is in a change position, that is, swung out of the processing machine, the starting of the processing machine is prevented. At best, the monitoring of this limit switch can also initiate a maintenance or changeover mode, which only involves a few specific ones

Manipulation of the processing machine allows. All signals of the limit switches can be transferred to a corresponding machine control, which evaluates the signals and releases or blocks corresponding functions and / or generates error messages, which are forwarded to a user or to another controller.

Another aspect of the present invention relates to a method for changing a tool of a processing machine, in particular on a processing machine as described herein. In particular, the method relates to changing a tool of a Cable processing machine, preferably a crimping press. The

Processing machine includes a tool changer, the one

Tool table and a swivel arm for pivoting the

Includes tool table. In particular, the processing machine comprises a tool changer as described herein. To change the tool, the tool table is rotated from a first position to a second position. The tool changer is rotated before turning

Tool table swung from a working position to a change position. The pivoting of the tool changer allows moving a located on the tool changer tool from a

Work item in a change position. In other words, one

Tool table can be swung out by the pivoting of the tool changer from the immediate sphere of influence of the machine, so that the tool changer is accessible.

Preferably, the pivot arm of the tool changer on the

Processing machine, in particular with a mounting base attached. This allows the precise and pinpoint pivoting of the tool changer as described herein. Preferably, a protective hood of the processing machine is opened before pivoting the tool changer.

By opening the guard, for example, the

Processing machine are turned off.

It may also be provided that before pivoting the

Tool changer a lock of the swing arm is released. This lock is released in particular before turning the tool table.

This allows the free pivoting of the tool changer.

To lock the swivel arm can be a

Position clamping device may be provided. It can be provided that only the release by opening the guard the Positionsklemmvorrichtu ng active sets and d ies this is actu bar, so that a lock or locking the tool changer in a certain position, in this case in a working position, can be solved. Preferably, before pivoting the tool changer a

In the case that the processing machine is a crimping press, is used to retool the tool, which is in the operating state of

Processing machine is located outside the protective hood, first removes a contact strip from the crimping tool. After that, the

Contact coil taken from the contact coil station. Also, a paper strip spool is removed from the paper winder. Afterwards an operating lever of a quick-release device is actuated and the tool is removed from the tool changer. The tool space outside the protective hood is empty afterwards. Thus, from this point on, a new tool can be placed on the tool changer. For this purpose, the quick-release device is also actuated and the tool is moved to the tool changer, in this case to the corresponding one

Tool place, put on. The paper reel corresponding to this tool as well as the corresponding contact reel are used in the corresponding paper winder, respectively contact reel place. Of the

Tool changer is thus ready to perform the method described here for changing a tool. For this purpose, only the protective cover of the processing machine must be opened, the

Tool changer can be swung out of the processing area, then the tool table can be rotated by 180 °

Tool changer swung back into the working position and the

Guard be closed. It can be provided that the tool is inserted and / or clamped, for example, in a plunger receptacle or a holder of the crimping press before closing the protective hood. For this purpose, the tool by means of Quick release device released from the tool table. A corresponding clamping device can be provided on the crimping press. This process can be done manually. However, it is also conceivable, for example, that when the tool table is pivoted back, the tool is inserted directly into the plunger receptacle or a holder of the crimping press.

If the crimping press and the corresponding tool within the crimping press as described hereinbefore are released from the tool table, it is necessary to first release the tool from the clamping device of the crimping press after the end of operation with the protective hood open and before turning the tool table, then onto the tool table of the crimping press

The baffles 123, 123 'are designed and arranged such that they extend around the pivot arm 20 around, that is, a

Contact band corresponding to the pivot arm 20 or one

corresponding extension of the pivot arm 20 is guided. In other words, the baffles 123, 123 'offset relative to a longitudinal extent of the pivot arm 20. Since the baffles 123, 123 'extend from a plane below the pivot arm 20 to a plane above the pivot arm 20, this embodiment of the baffles 123, 123' allows the rotation of the tool table 10 by +/- 180 °.

FIG. 3 shows the tool changer 1 from FIG. 2 in one

Top view. The tool stations 11, 11 'are arranged on the tool table 10 centrally symmetrical about a pivot pin 17 (see FIG. 5). The tool table 10 is connected to the pivot arm 20 via a pivot pin 25 with the mounting base 24 and thus pivotally mounted on the mounting base 24. The mounting base 24 is connected at the appropriate place with the processing machine 100 (see Figure 1). Thus, the tool changer 1 is pivotally mounted on the processing machine 100.

FIG. 4 shows a side view of the tool changer 1 from FIG. 3 in the direction of the arrow X (see FIG. 3), wherein the tool changer 1 is shown in its operating position. In the operating position extends the

Swivel arm 20 in a substantially horizontal position between the mounting base 24 and the tool table 10th FIG. 5 shows a partial view of the view according to FIG

sliced illustration. The cutaway view extends to the section A-A according to the figure 4. In the figure 5 it is visible that within the pivot arm 20, the locking device 23 is located and extends through the pivot arm 20. The

Locking device 23 is presently designed as a push rod. This push rod has two front ends, wherein one of the front ends has a head, which is designed as a counterpart 21, 22. The counterpart 21, 22 is in the representation according to FIG. 5 in contact with a first stop 15, which is formed on the pivot pin 17. The first stop 15 is present as a milled on

Pintle 17 is formed and has a flat surface. Accordingly, the counterpart 21, 22 has a likewise flat surface. These flat surfaces are in operative connection with each other. By this arrangement, a rotation of the tool table 10 is prevented, since this is fixedly connected to the pivot pin 17. The locking device 23 is held in the position shown in Figure 5 by means of an unspecified spring which is presently in a recess of the locking device 23. This unintentional unlocking of the tool table 10 is prevented.

FIG. 6 shows a detail view from FIG. 5 in a position of the swivel arm 20 rotated relative to FIG. 5. In FIG. 6, the swivel arm 20 is pivoted relative to the mounting base 24 along the arrow P2. Within the mounting base 24 is an actuating pin 26th

arranged, which has a fixed to the mounting base 24 position. The locking device 23 is in contact with the front end opposite the counterpart 21, 22

Actuating pin 26. Since the locking device 23, that is, the front end, which is in contact with the actuating pin 26, is arranged eccentrically to the pivot pin 25, the

Locking device 23 moves by pivoting the pivot arm 20 relative to the pivot arm 20 in the direction of arrow PI. In this case, the compression spring in the recess of the locking device 23rd pressed together. Accordingly, the head on the second end face of the locking device 23 moves with the counterpart 21, 22 relative to the pivot arm 20 and releases the first end stop 15. The pivot pin 17 and thus the tool table 10 (see Figure 5) can thus, in this case rotate counterclockwise. It can the

Tool table 10 can be rotated by 180 °, so that the second

End stop 16 at the position of the first shown in Figure 6

End stop 15 occurs. By pivoting back the pivot arm 20 against the direction of the arrow P2 thus the counterpart 21, 22 are brought into engagement with the second end stop 16. Thus, the

Tool table 10 is rotated in a position shown in Figure 5 by 180 °.

The position which the tool changer 1 has in FIG. 6 is referred to as a change position. To define this exchange position can

For example, in the region of the mounting base 24, a first

End position stop 40 may be provided.

A second limit stop 41 for defining the working position can also be provided. Both limit stops 40, 41 each have a limit switch 42. This makes it possible to transmit the respective position, for example, to the control of the processing machine. These

However, limit stops 40, 41 for defining the working position and / or the change position represent only one of the possible alternatives or combinations. A second alternative is described below

Referring to Figure 7 explains. FIG. 7 shows a detailed side view in the direction of arrow Y from FIG. 4. The view according to FIG. 7 is partially cut open as far as the section line B-B according to FIG. In the partially cutaway view of Figure 7, the pivot pin 17 is visible, which is connected to the tool table 10. The two tool stations 11, 11 'are one

Turned clockwise in the direction of the arrow.

FIG. 8D shows the tool changer 1 after the turning process of the tool table 10. The position shown in FIG. 8D corresponds to that however, with the difference that the tools 50 and 50 'have changed places. From the position according to FIG. 8D, the tool changer 1 can be pivoted into the position according to FIG. 8A. For the finished setting up of the present crimping press, the tool 50 'in the position according to FIG. 8D is lifted off the tool table 10 and inserted into a corresponding holder and / or clamping device and / or plunger holder of the crimping press. The contact coil 121, 121 'and the paper winder 13, 13' (see Figure 2) remain substantially unchanged. After that, the protective hood 101 can be turned against the

Arrow direction P3 (see Figure 1A) to be moved. This now is the tool 50 'within the protective cover 101 and the tool 50 can be replaced accordingly. The replacement of the tool 50 is done by opening the quick release device 14 (see Figure 9) and by the replacement of the corresponding contact coils and the

corresponding paper winder.

FIG. 9 shows the view according to detail D from FIG. 2. A tool 50 is arranged on the tool place 11. The tool 50 is held by the quick release device 14. The quick-release device 14 has a retaining claw 141, which is actuated by the actuating lever 142. The operating lever 142 is by a spring, not shown here

biased such that it permanently assumes the position shown in the figure 9, even if no tool 50 is clamped on the tool place 11. By operating the actuating lever 142, the retaining claw 141 is released and moved in the view according to the figure 9 to the left front.

As a result, the tool 50 can be removed from the tool space 11.
