In FIG. 1 First, the principle of action of an electromagnetic switch 7 is shown according to a particular embodiment. One or more ferromagnetic articles 1 are conveyed via a feed path (see inflow 20) of the switch W fed and depending on the control or energization of an electromagnet 3 and / or an opposite electromagnet 4, the ferromagnetic objects 1 are deflected in a predetermined or predeterminable deflection 11-1 and 11-2, eg laterally (eg, to the left or right) deflected for example, to be passed by a separating device 23 accordingly laterally (eg, to the left or right). In this case, the ferromagnetic objects 1 can for example be supplied substantially from above in order to exploit the gravitational force of the ferromagnetic objects 1, so that the ferromagnetic objects 1 are supplied to the switch 7 by gravity.

In FIG. 2 the electromagnet 3, 4 is shown in detail. The electromagnet 3, 4 has a magnet housing 5 and a magnetic core 6. By applying a suitable voltage to the magnet core 6 provided with windings, it becomes magnetic and can thus attract ferromagnetic objects arranged in its magnetic field. By switching off the electrical voltage, the magnetic field of the magnetic core 6 is substantially completely reduced or removed or removed, so that an attraction of ferromagnetic objects 1 no longer occurs. Here are, as in FIG. 2 is shown, the magnetic core 6 and the magnet housing 5 is formed substantially arcuate or circular segment-like, so that the objects 1 along the (arc) arc of the electromagnet 3, 4 can slide.

In FIG. 3 a braiding machine according to a particular embodiment with at least two impellers 10 is shown. Each of the impellers 10 has at least one feed groove 9 into which a clapper 12 can at least partially enter to be rotated by the impeller 10. For this, each clapper 8 has a baton foot 14 and a guide groove 15. When the feed groove 9 of the impeller 10 engages in the guide groove 15 of the clapper 8, the clapper 8 is positively connected or coupled to the impeller 10 and by the rotation of the impeller 10th taken or transported. Furthermore, a switch 7 is disposed at a position between the vaned wheels 10. This position allows a transfer of a bobbin 8 of one of the impellers 10th on the other of the impellers 10th

As further in FIG. 3 is shown, the clapper 8 has a guide member 12 which is arranged substantially coaxially with the bobbin base 14 with guide groove 15. However, the invention is not limited thereto. The guide element 12 may also not be arranged coaxially with the guide groove 15. The guide member 12 serves to deflect the bobbin 8 within the switch 7, as in the FIGS. 4 and 5 is shown.

In the FIGS. 4 and 5 is arranged between the vanes 10 switch 7 is shown enlarged. This switch 7 has a two-way or paths or deflection paths 11a and 11b branched track 11, which has a circular arc shape corresponding to the circular arc shape of the vanes 10. This means that a raceway 11 of one of the two impellers 10 strikes a further raceway 11 of the adjacent impeller 10, so that two raceways 11 are arranged or provided corresponding to the impellers 10 within the switch 7. The guide element 12 can pass through the raceway 11 of the switch 7 and be deflected depending on the energization of one of the two electromagnets 3, 4, to enter the respective other raceway 11 of the adjacent impeller 10. In other words, the guide element 12 selectively deflected by means of the targeted energization of the switch 7 in a corresponding output path 11 a and 11 b and thus the corresponding impeller 10 are supplied.

It shows FIG. 4 the activation of the left magnet 3, so that the guide member 12 maintains its track 11 on the left vane 10 (not shown). In this case, the cylindrical guide member 12 rolls on or on a guide surface 3a of the left magnet 3 to run (in particular with low friction) over the electromagnet 3 away or to slide or to roll.

Preferably, for this purpose, the guide element 12 is cylindrical and more preferably rotatably mounted on the clapper 8. According to a simpler embodiment, however, can also be applied to the rotatable mounting of the Guide element 12 can be omitted.

FIG. 5 shows a handover of the bobbin 8 with the guide member 12 from the raceway 11 of the right vane 10 (not shown) to the raceway 11 of the left vane 10 (not shown). After the entry of the guide element 12 into the switch 7, the guide element 12 initially rolls on the guide surface 4a of the right electromagnet 4. However, since the right electromagnet 4 is deactivated and only the left electromagnet 3 is energized to generate an electromagnetic field, the guide member 12 of the clapper 8 is attracted by the left electromagnet 3 and thus changes to the left side to rest on the guide surface 3a to unroll the left electromagnet 3. In this way, the guide member 12 is transferred into the raceway 11 of the left impeller 10.

FIG. 6 now shows a reversal of direction of a bobbin 8 with the guide member 12. In this case, the adjacent vanes 10 rotate in the region of the switch 7 in opposite directions. This means that the vaned wheels 10 actually rotate in the same direction, ie, as in FIG FIG. 6 is shown, clockwise. This means that the left part of the arc of the right vane 10 located inside the switch 7 moves upward while the right arc of the left vane 10 is moving down. Thus, the movement within the raceway 11 of the left impeller 10 is opposite to that within the raceway 11 of the right impeller 10.

Now, when a clapper 8 enters with its guide element 12 in the switch 7, the guide member 12 is attracted by the activated left electromagnet 3 of this and is passed from the right impeller 10 to the left impeller 10.

The transfer means that the guide groove 15 exits from the feed groove 9 of the right impeller 10 and enters a corresponding feed groove 9 of the left impeller 10. Accordingly, the clapper 8 is now released from the right impeller 10 and advanced by the left impeller 10, so that, as in FIG. 6 is shown, the guide member 12 (eg, approximately in the middle of the switch 7) its direction substantially reverses and down the track 11 of the left impeller 10 follows.

It is understood that in the application of a plurality of impellers 10, which are each connected by a plurality of switches 7, by means of the guide elements 12 in conjunction with the guide groove 15 which is moved by a feed groove 9 of the impeller 10, a very flexible Type of movement of a clapper 8 can be achieved. In particular, a movement pattern of the bobbin 8 can be easily changed by energizing either the left solenoid 3 or the right solenoid 4 of one of the plurality of switches 7, around the ferromagnetic guide member 12 and thus the respective beater 8 guided thereby to divert left or right.

In this case, each of the impellers 10 may have at least one feed groove 9 or a plurality of feed grooves 9. The energization of the electromagnets 3, 4 need only be adapted to the speed of the impellers 10 and clocked accordingly. A manual intervention for the conversion of a switch 7 or a mechanical switching of the switch 7 is omitted in this construction. In this way, a deflection or web change of a bobbin 8 can be carried out in a very fast manner and very flexibly.

In FIG. 7 a preferred embodiment of a clapper 8 is shown. This clapper 8 has concentric with the bobbin leg 14 with the guide groove 15, a connecting shaft 13 to which the guide member 12 is rotatably supported by means of a pair of ball bearings 12a. Such a rotatably mounted guide member 12 can roll in a very gentle manner and friction on the corresponding guide surfaces 3a, 4a of the electromagnets 3, 4.

However, the invention is not limited to such a rotatable arrangement of the guide member 12. For example, it is possible to dispense with the ball bearings 12a when the guide element 12 is made of one particular low-friction material, such as Teflon or a chromium-coated metal surface exists or has.

FIG. 8 shows a modification of the guide member 12, in which the guide member 12 is not cylindrical, but rectangular or polygonal with pointed ends 12c. Due to the sharpened ends 12c, the guide element 12 is easily inserted into the web 11 of the switch 7. Side surfaces 12b slide along the corresponding guide surfaces 3a, 4a of the electromagnets 3, 4. Here, the entire guide element 12 is made in particular of a corresponding low-friction plastic or metal. It is also conceivable that the ends 12c are at least partially rounded.

As further in FIG. 8 is shown, the electromagnets 3, 4 at a corresponding pivot point 3b, 4b be pivotally mounted to be moved with the guide member 12 a certain amount. Preferably, the electromagnet 3, 4 for this purpose by a spring (not shown) positioned in its center or rest position or biased toward this. By appropriate loading or frictional force of the electromagnet 3, 4 is displaced out of its center position, in particular pivoted about the pivot point 3b, 4b. After the contact between the guide member 12 and the guide surface 3a, 4a is released, the solenoid 3, 4 returns due to the spring force of the spring (not shown) in its central position or rest or initial position.

This embodiment of the displaceable or pivotable electromagnets 3, 4 is preferably applied to a non-rotatably mounted guide member 12. The application is not limited thereto, but can also be applied to a rotatably mounted guide member 12.

In the FIGS. 9 to 15 Different types of round braiding machines with corresponding points 7 according to the invention are shown.

In FIG. 9 a braiding machine is shown, in which a plurality of impellers 10 on a (only partially shown) circle is arranged with the center M. Between two adjacent impellers 10, a switch 7 is arranged according to a particular embodiment in each case. Each of the impellers 10 has in each case by about 90 ° along its circumference offset a conveyor groove 9, thus a total of four conveyor grooves 9 to move the clapper 8 along the circumference of the impeller 10. According to the invention, however, a different number of feed grooves 9 (eg, one, two, three, or five or more feed groove (s)) per impeller 10 are also conceivable. In this way, the clappers 8 can be moved along the circumference of a single one of the impellers 10 or, alternatively, passed to the adjacent impeller 10. It is understood that in this way a very flexible braiding process can be carried out without the machine having to be converted or rebuilt. Furthermore, the transfer of a bobbin 8 through the switch 7 in a very fast manner, only by driving or energizing one of the two electromagnets 3, 4 done.

In FIG. 10 another embodiment of a particular embodiment of a braiding machine is shown, in which a second concentric circle of impellers 10 around the center M is arranged around. In this way, the clappers 8 can be moved along one of the two concentric circles formed by the plurality of vanes 10, respectively. In addition, at least one switch 7 is preferably arranged between adjacent vaned wheels 10 of one of the circles and one impeller 10 of the other circle. In the presentation of FIG. 10 in each case a switch between adjacent vanes 10 of the one circle and the other circle is arranged. In this way, a clapper 8 can be transferred from one of the concentric circles to the other of the concentric circles. In this way, the braiding becomes even more flexible.

It will be understood that the invention is not limited to the arrangement of two concentric circles on impellers 10 but may be arranged on a plurality, three, four, five or even more concentric circles of impellers 10. Furthermore, the invention is not based on impellers 10 limited with four conveyor grooves 9, but it can be arranged any number of conveyor grooves 9 on the impeller 10 or on a plurality of impellers 10.

Another possible embodiment is the placement of a single impeller 10 between two concentric circles of a plurality of impellers 10, as in FIG FIG. 11 is shown. In this way, a transfer of a bobbin 8 from one of the concentric circles on the other of the concentric circles on the individual between the two concentric circles arranged impeller 10 can take place. It is understood that by such an arrangement of a single impeller 10 between concentric circles of impellers 10 further flexibility of a braiding process is possible.

However, the invention is not limited to the arrangement of concentric circles of impellers 10. Rather, the impellers 10 can also be arranged according to a rectangle or a predetermined or predeterminable pattern or matrix in rows and columns, such as in FIG. 12 is shown. Furthermore, the plurality of impellers 10 may be arranged with the interposed switches 7 along the circumference of a cylinder, such as in FIG. 13 is shown. It is understood that a variety of in FIG. 13 shown cylindrical circles of impellers 10 can be arranged side by side. For simplicity, in FIG. 13 however, only a cylindrical circle of vanes 10 is shown. FIG. 14 shows an example of two cylindrical circles of impellers 10. In this case, the adjacent cylindrical circles in turn can each be connected by one or more switches 7.

Furthermore, it is possible to arrange the vanes along the surface of a hemisphere, as in FIG FIG. 15 is shown.

The invention is not limited to an arrangement of impellers 10 according to the FIGS. 9 to 15 but any other arrangements of a plurality of impellers 10 may be made within the scope of the invention become.

The invention is not limited to an electromagnetic switch 7 for a braiding machine, but it can also other ferromagnetic objects 1 than the clapper 8 with the guide elements 12 are influenced by such an electromagnetic switch 7 in its trajectory.

Conceivable here is, for example, a sorting device for ferromagnetic objects 1, which are alternatively conducted in one or another way. For this purpose, a corresponding sorting device, as in FIG. 1 is shown, for example, a feed 20, which is preferably formed in a substantially funnel-shaped, and in which a plurality of ferromagnetic objects 1 is supplied from above. Further down within a path of movement of the ferromagnetic objects 1 is a pair of electromagnets 3, 4, depending on the energization of the ferromagnetic objects 1 to the left (deflection 11a) to the left electromagnet 3 or to the right (deflection 11 b) to the right electromagnet 4th divert laterally. In this way, the ferromagnetic objects 1 are discharged to the left or right in a discharge 21 of the sorting device. Below the drain 21 may be a separating device 23, which has a drain path to the left or right or branches.

Preferably, the sorting device may further comprise a slider 22, in particular upstream of the electromagnets 3, 4, to control a supply of the electromagnetic objects 1 due to the gravity of the same. In other words, the slider 22 may selectively block or release the passage of one or more ferromagnetic articles 1 by at least partially inserting or pulling the slider 22 into or out of the path of the ferromagnetic articles 1.

In this way, the sorter can separate the ferromagnetic articles 1, for example, according to good parts and bad parts. However, the invention is not limited thereto, but ferromagnetic articles 1 can also according to completely different criteria in at least two Lanes or even multiple lanes are divided. For this purpose, for example, a plurality of corresponding sorting devices with a pair of electromagnets 3, 4 are arranged one behind the other to have a plurality of branches or sorts.

By the electromagnetic force sorter directing an article to a corresponding path, for example, "good" and "bad parts" may be separated.

Thus, a switch 7 is provided for selective sorting, deflection, feeding of ferromagnetic elements 1. In this case, the switch 7 has at least two electromagnets 3, 4, which are configured substantially arcuate or circular. The magnets 3, 4 may be fixed or fixedly mounted in the switch 7 or, alternatively, movably mounted or displaced on an axle 3a. The ferromagnetic elements 1 are moved by a guide or conveying element 12 through the switches 7. Advantageously, the switch 7 can also be used to guide bobbins 8 of a braiding machine. In this case, the clapper 8 can be flexibly transferred to another impeller 10. This opens up new possibilities with regard to the flexibility of braids. Further, this invention provides a significant reduction in braiding time in complex braids.
