Abstract

Reconfiguring a rotary table (1) significantly increases flexibility in rotary cycle assembly systems since the rotary table (1) can be retooled in a single configuration step to be able to process workpieces of a different type by providing the rotary table with two holders (A, B) and turning said holders (A, B) by a configuration angle (K). It is no longer necessary to dismount the entire rotary table (1) and replace the same with another rotary table (1) to process an different class of workpieces. The rotary table (1) therefore opens up new possibilities for combining circular indexing tables in automatic rotary cycle systems, thus satisfying the need for more flexibility in "design for flexibility" and "plug & produce" contexts. Reconfiguring the rotary table (1) allows the production units (F1, F2) to be used in a more flexible manner and thus also render the extent and duration of manual operations significantly more flexible so that manual and mechanical operations can be synchronized to a high degree and the whole process can be made more efficient.

Turntable, circular table, assembly system and operating procedures

The invention relates generally to assembly conveyor systems. These usually consist of various functional areas such as the transport of workpieces, the repeatable positioning of workpieces, various processing methods used on the workpieces, as well as the use of appropriate sensors and associated data processing. The workpieces are, for example, components.

Turntables and circular tilt tables are used with high efficiency in the assembly of individual parts to complex components. The assembly consists of different and numerous individual steps for the processing of components and their assembly. The term "Kreisteiltisch" is used here to include not only the turntable itself but also those elements that do not belong to the turntable as a plate in the narrower system, but are directly required for its attachment, management and operation. For the entirety of this device, the term Kreisteiltisch is in common use.

As a rule, the turntables are equipped with workpieces and fed successively to different production stations. Individual processes can be automated. Are known turntable, the rotational movement is operated automatically. Since very complex operations are carried out when assembling component systems that are carried out on turntables, a comprehensive check of these processes with regard to the optimal execution is desirable. In addition, machining operations are possible whose automation causes great difficulties. From DE 10 2010 042 086 AI a Kreisteiltisch is known, which provides a so-called indexing or indexing of the turntable for accurate and repeated positioning of workpieces. This generally means the adjustment of workpieces at a predetermined repeatable position. From the publication is also known to mark the division on the turntable by the distribution of firmly connected to the turntable cam rollers. By means of an indexing unit, a cam roller is usually picked up, damped and centered at a specific graduation which corresponds to a corresponding machining operation. For this purpose, a freewheel is provided in the turntable bearing, which prevents a turntable movement after retraction into the damping against the rotational movement. After machining at such an indexed position of the turntable and according to the components thereon, the cam roller is released within the indexing unit, so that the turntable can be initiated for a further rotation by one pitch with subsequent re-positioning of the following cam follower. In doing so, a cam roller entering the indexing unit is gently indexed, ie braked and centered.

In conventional rotary indexing machines, the machining of a workpiece takes place by exactly one revolution in the rotary indexing system. Here, manual and mechanized operations are fixed and run in parallel. Furthermore, the manual and mechanized operations usually have different process times.

The workpieces are positioned and fixed on the turntable in so-called receptacles (workpiece carriers) for processing by the automated production units. Here, the images are permanently assigned to the corresponding production units.

It turns the task, a turntable, a Kreisteiltisch, a mounting system and a method of operation indicate which increase the flexibility of manufacturing.

This object is achieved by a turntable for receiving, transport and fixation of workpieces, in which a division is predetermined on the turntable, which divides this with a pitch angle into segments, the number of segments multiplied by the pitch angle results in 360 ° and wherein the turntable is in particular circular and the segments are in particular circular sectors. The turntable is rotatable in a working operation in each case by the pitch angle. It is characterized in that an integer factor is given, which is at least 2. A configuration division on the turntable is predetermined, which subdivides this with a configuration angle into configuration segments, the configuration angle multiplied by the factor giving the pitch angle. For each configuration segment, recordings for workpieces are set up on the turntable offset by the configuration angle. Furthermore, the turntable is set up to rotate all recordings in a single configuration step by the configuration angle, so that they are positioned offset in the operating mode of the turntable to the configuration angle.

The following effects and advantages need not necessarily be achieved by the subject matters of the independent claims. Rather, these may also be effects and advantages, which are achieved only by individual embodiments, variants or developments.

The turntable allows easy reconfiguration. This is also suitable for multi-stage joining processes, in which a workpiece is fed to its circulation around the turntable several automated production units. The pitch angle is for example 120 °, resulting in three circular sectors as circle segments. As a factor, for example, 2 is selected, resulting in a configuration angle of 60 °. The recordings on the turntable are rotated by the configuration angle, whereby in each case other recordings come under the automated production units. This assumes that the automated production units for workpieces of a different type can be converted or reprogrammed.

The fact that the turntable can be converted to workpieces of a different type in a single configuration step significantly increases the flexibility of use and, as a result, the efficiency of the round - clocked mounting system. By no longer supplying all the recordings on the turntable to the manufacturing units during operation, the versatility of the rotary indexing machine with respect to a harmonious balance of the assembly stations (i.e., the production units and the manual workstation) is significantly increased. Here, the fact is used that the production units are often used flexibly for a variety of joining processes and also have suitable process times for this purpose. The reconfigurable turntable allows various operations to be carried out

To realize workpieces with a single turntable. To achieve a comparable effect, you had to remove the entire turntable and replace it with a new turntable with suitable recordings. The turntable thus opens up a new combinatorial

Potential of circular tilt tables in rotary indexing machines, which meets the requirements for increased flexibility in the context of a "Design for Flexibility" and "Plug &Produce". Furthermore, the contents and, consequently, the duration of the manual operations can now be made much more flexible, which enables a high synchronization of manual and mechanical work in terms of process efficiency. The combinatorial potentials of a turntable or Kreisteiltisches be systematically developed with the turntable with regard to its positioning. This means that multi-stage processes can now be implemented efficiently on a system without having to change the rotary table. Multi-level here means that a workpiece is fed to its circulation around the turntable several automated production units. The combinatorial potentials result from the reconfiguration of the turntable, the stage of the assembly process and possibly also multiple rotations of a workpiece in the mounting system.

According to one embodiment, a first receptacle for receiving a workpiece of the first type is set up on the turntable offset by the pitch angle for each segment. Furthermore, on the turntable, offset from the first recordings by the configuration angle, second recordings are each set up to record a second type of work piece. This embodiment has the advantage that the turntable can be configured in a single configuration step optionally for machining the workpieces of the first or the second type. The types are, for example, different types of components. Alternatively, a workpiece of the first type can be converted into a workpiece of the second type by one or more joining processes.

In a further development, for each segment, first recordings for receiving a plurality of workpieces of a first group in mutually adjacent relative positions are arranged on the turntable offset by the pitch angle. Furthermore, on the turntable, offset from the first recordings by the configuration angle, second recordings for a record of a plurality of workpieces of a second group are set up in mutually adjacent relative positions. This development has the advantage that the inclusion of several workpieces allows processing of these workpieces with multiple revolutions around the turntable. According to one embodiment, the turntable on an upper part, in particular a support plate on which the receptacles are mounted. The turntable further consists of a lower part which is equipped with at least one cam roller, wherein the pitch is indicated on the turntable by the arrangement of the at least one cam roller. Furthermore, the turntable is set up in the single configuration step to rotate and lock the upper part relative to the lower part by the configuration angle.

In a development of this embodiment, the upper part has a slot which extends along a circular arc of a circle segment with the configuration angle as the midpoint angle. Further, the turntable on a pin, which is firmly anchored in the lower part and protrudes into the slot in the upper part, so that the upper part abuts against the lower part against rotation about the configuration angle with one end of the slot on the pin. Furthermore, the turntable has an upper bore in the upper part and at least two lower bores in the lower part, which are arranged so that the upper part relative to the lower part after rotation by a fastening means, in particular a screw or a pin, can be locked ,

The circle table includes the turntable. It is equipped with a bearing and a freewheel through which the turntable is rotatably mounted. He is also equipped with at least one cam roller. The circular tilt table contains at least one indexing unit for automatically receiving and centering the at least one cam roller. The division on the turntable is determined by the arrangement of at least one cam roller. The at least one Cam follower cooperates with the indexing unit in such a way that the turntable is released only after processing of the workpieces for a next rotational movement. According to one embodiment of the Kreisteiltisches the turntable is mounted with the storage and the freewheel together with the indexing on a support, so that the turntable is rotatable relative to the indexing unit and the at least one cam roller during rotation of the turntable by the indexing is feasible.

It is advantageous to turn the turntable further depending on upcoming work processes at the optimum time, or to initiate further rotation. After the further rotation corresponding to a pitch on the turntable, the next cam follower moves against a stop of the indexing unit. The stop is spring-mounted in the tangential direction to the turntable and can be advantageously used for damping by a damping element is used as a basis for the stop.

The use of a freewheel in conjunction with the turntable prevents the turntable from turning back when braking a cam follower when entering the indexing unit. By means of a centering element, which piston-supported radially to the turntable, on both sides of the currently located in the indexing unit cam roller and retractable, the cam roller is centered. In this state, the workpieces inserted in the receptacles on the surface of the turntable are located exactly in front of a production unit, or exactly in a desired working position in front of an operator.

The mounting system includes the turntable and / or the circular tilt table. It also comprises a plurality of production units, in particular welding units, Lotbandvorschübe and / or drilling units. The production units are optional for machining the workpieces of the first type or the workpieces second type configurable. Accordingly, a reconfiguration of the production units in the course of the single configuration step or in addition to this feasible. In an alternative embodiment, the mounting system is equipped with a first production unit, which is optionally configurable to edit a first group of a first workpiece inserted in the first group or an inserted into a second left recording workpiece of the second group. Furthermore, the mounting system is equipped with a second production unit, which is optionally configurable to edit a workpiece inserted in a first right receiving the first group or a second right-hand recording workpiece of the second group. A corresponding reconfiguration of the first production unit and the second production unit is in the course of the single configuration step or in addition to this feasible. According to one embodiment of the mounting system, the factor is greater than 2, wherein a corresponding number of additional receptacles on the turntable and associated configurations of the production units are set up. In the method for operating the turntable, the Kreisteiltisches and / or the mounting system, the turntable is fitted in work operation in a first phase of operation with workpieces and rotated by the pitch angle. The first operating phase may comprise a plurality of rotations or operating hours until, for example, a predetermined quantity of workpieces has been processed. Then the work operation is terminated. All recordings are rotated in the single configuration step by the configuration angle. Subsequently, the turntable is in work operation in a second phase of operation equipped with workpieces and the

Split angle rotated, where the images are positioned offset by the configuration angle. According to one embodiment, the manufacturing units are reconfigured in the course of the single configuration step or in addition to this. In a further development of the turntable is loaded in work operation in a first phase of operation with workpieces of the first type and rotated by the pitch angle, the manufacturing units edit the workpieces of the first type. The first operating phase may comprise a plurality of rotations or operating hours until, for example, a predetermined quantity of workpieces of the first type has been processed. Then the work operation is terminated. All recordings are rotated in the single configuration step by the configuration angle. The manufacturing units are reconfigured in the course of the single configuration step or in addition to this for machining workpieces of the second type. In turn, the turntable is loaded in work operation in a second phase of operation with workpieces of the second type and rotated by the pitch angle, the recordings are positioned offset by the configuration angle and the manufacturing units edit the workpieces of the second type.

In an alternative development of the turntable is loaded in work operation in a first phase of operation with workpieces of the first group and rotated by the pitch angle. In this case, a first production unit processes workpieces of the first group that are inserted into the first left-hand receptacle and a second production unit processes workpieces of the first group that are inserted into the first right-hand receptacle. The first operating phase may include a plurality of rotations or operating hours until, for example, a predetermined amount of workpieces of the first group has been processed. Then the work operation is terminated. All recordings are rotated in the single configuration step by the configuration angle. The production units are reconfigured in the course of the single configuration step or in addition to this for processing workpieces of the second group. riert. The turntable is then fitted with workpieces of the second group in work operation in a second operating phase and rotated by the pitch angle, wherein the recordings are positioned offset by the configuration angle. In this case, the first production unit processes workpieces of the second group which are inserted into the second left-hand receptacle and the second production unit processes workpieces of the second group which are inserted into the second right-hand receptacle. The assembly of components and their joining is advantageously carried out by the use of the turntable in conjunction with several production units, which together form a mounting system. Manual and automated processes are mixed.

The turntable and the Kreisteiltisch can be used in conjunction with automated manufacturing units, in particular

Welding units, Lotbandvorschüben or drilling units, for semi and fully automatic machining of workpieces, in particular components, are used. Here, several production units, each with a turntable to assemble a mounting system and operate several such mounting systems side by side with a cross-material flow.

Exemplary embodiments will be described below with reference to the schematic figures which do not limit the invention. The figures show in detail: FIG. 1 a mounting system 13 with a turntable 1 and automated production units F1 and F2,

FIG. 2 shows the top view of a circular tilt table with turntable 1, mounting and freewheel 2 and indexing unit 8 with cam follower 3 positioned therein, the turntable 1 being shown completely and transparently, 3 shows a turntable 1 for a two-stage joining process for workpieces of a first type, FIG.

4 shows a turntable 1 for a two-stage joining process for workpieces of a second type, a reconfigurable turntable 1 for workpieces of a first type and workpieces of a second type in a first configuration, the reconfigurable turntable 1 of Figure 5 in a second configuration, a reconfigurable Turntable 1 for workpieces of a first and a second group, wherein the workpieces in a single-stage joining process each pass through several revolutions around the turntable 1, Figure 8 shows an example of a hybrid mounting system 13 with a variably indexable turntable 1, which after further rotation by one pitch 9 is an example of a hybrid mounting system 13 with a reconfigurable turntable 1,

FIG. 10 shows a section through a reconfigurable turntable 1,

11 shows a plan view of a reconfigurable turntable. 1

Figure 1 shows a mounting system 13, which is composed of honeycomb arranged manufacturing carrier modules 21. The manufacturing carrier modules 21 have a trapezoidal shape and are connected to each other. In the middle of the honeycomb arrangement there is a turntable 1 or a circular part. table on which workpieces are used in recordings. The turntable 1 is then rotated by an operator 26 in the arrow direction in a clockwise direction, whereby the inserted workpiece successively different automated production units Fl and F2, which are mounted on the operator 26 opposite the production carrier modules 21, respectively. For example, a soldering of two workpieces is carried out by a first production unit F1 and a further machine operation by a second production unit F2.

Furthermore, FIG. 1 shows arrows on the left and right side of the operator 26. These indicate that the operator 26 receives workpieces from the left for processing and then forwards them to the right. As can be seen from FIG. 1, the operator 26 in each case accesses the production units F1, F2 via the turntable 1, which are not located on the production carrier module 21 on which the operator 26 stands. On the contrary, the operator 26 can also operate the production units F1, F2 on the production carrier modules 21 opposite to him by means of the turntable 1. The working radius of the operator 26 is thereby significantly increased. The turntable 1 forms the mounting system 13 in conjunction with the surrounding six production carrier modules 21 and the production units F1, F2.

The turntable 1 shown in the following figures, which can be at a determinable time in a rotary motion, here simultaneously a transport movement, can be placed in the end position of the rotational movement, d. H. if he has rotated by one pitch, automatically fixed. After the rotational movement, for example, with other manual or automatic welding or soldering, bending or similar procedures can be started.

Figure 2 shows a Kreisteiltisch with a turntable 1 in a sectional side view in detail, distributed on the cam rollers 3 in a predetermined pitch over the circumference are. FIG. 2 also shows a bearing and a slide 2, a centering element 5 and an indexing unit 8 and a common carrier 11. In the operating state shown in FIG. 2, the cam roller 3, which has moved into the indexing unit 8, is not through the centering element 5 centered and fixed. Thus, the cylinder 6 is retracted and has the centering element 5 offset relative to the turntable 1 radially outward in the position shown. In a basic position not shown in Figure 2, the cam roller 3 of the turntable 1 in the indexing unit 8 can be centered and fixed, whereby the turntable 1 can be positioned. In the indexing unit 8 are also a stop 4 and a damping element. To monitor the stop 4, the indexing unit 8 contains an initiator.

FIG. 2 clearly shows that neither the stop 4 nor the centering element 5 obstruct the path of the cam roller 3 within the indexing unit 8. Thus, the triggering or initiation of a rotary movement of the turntable 1 can be retrieved by an actuating handle 10. If this rotational movement is triggered, the turntable 1 continues to rotate by one pitch, so that the next cam roller 3 enters the indexing unit 8.

At the start of a rotary movement, a cam roller 3 located in the indexing unit 8 is released in each case. For this purpose, the completion of machining of the workpieces by the automated production units around the turntable 1 is normally necessary. Only then can the turntable 1 be released and a new rotary motion initiated. The spring-supported in the radial direction stop 4 presses in the released state against the cam roller. 3

By manually tapping the turntable 1, for example, the adhesion between stop 4 and cam roller 3 can be solved. The turntable 1 rotates by one pitch and the stop 4 takes on the next cam roller 3, the is braked in the stop 4 by means of the damping element. The stop 4 is mounted in the tangential direction to the turntable 1 and is held in the home position via the damping element.

If the cam roller 3 hits the stop 4, the turntable 1 is braked via the damping element. A turning back of the turntable 1 during the braking phase is prevented by the freewheel 2 in the turntable storage. By the centering element 5, which is driven by an example pneumatic cylinder / piston, the cam roller 3 and the turntable 1 is centered. The automated production units start to work. By the indexing unit 8 and the cam rollers 3 on the turntable 1, the turntable 1 is depending on its pitch, which correlates with the position of the recordings, which are located on the turntable 1, automatically captured in the indexing unit 8 by a cam roller 3, damped and centered. For this purpose, a freewheel 2 is necessary in the turntable bearing, which prevents a turntable movement after retraction into the damping counter to the direction of rotation. If the rotation is initiated manually, it makes sense to use a two-hand release for safety or to use a foot switch.

In Figure 3, a turntable 1 is shown, on which a division is given, which divides this with a pitch angle T = 120 ° in three circular sectors as segments. As previously described, the turntable 1 is rotatable about the pitch angle T in a work operation. The rotation is initiated by an operator 26. The operator 26 also inserts workpieces of a first type into first receptacles A on the turntable 1. These are supplied by the rotation of a first production unit F1 and a second production unit F2, so that this is a two-stage joining process. FIG. 4 shows, analogously to FIG. 3, a further turntable 1, which is likewise divided into three segments by a pitch angle T of 120 °. Notwithstanding Figure 3, the turntable 1 has second receptacles B, which receive workpieces of a second type. These are also supplied in a two-stage joining process by the rotation of the turntable 1 of a first production unit Fl and a second production unit F2. In order to change from the two-stage joining process of FIG. 3 to the two-stage joining process of FIG. 4, it has hitherto been necessary to exchange the entire turntable 1 in order to obtain the required second receptacles B.

Figure 5 shows an embodiment of a umkonfigurierba- ren turntable 1, which is equipped with both first recordings A for workpieces of a first type and with second receptacles B for workpieces of a second type. Also, this reconfigurable turntable 1 has a pitch with a pitch angle T = 120 °. In the configuration shown in FIG. 5, in each case the first receptacles A are fed to a first production unit F1 and to a second production unit F2 in a two-stage joining process. The turntable 1 from FIG. 5 fulfills the same function as the turntable shown in FIG. 3 in this configuration.

As can be seen from FIG. 5, the graduation on the turntable 1 is subdivided once again by the integer factor 2 into a configuration division. The configuration angle K is thus 60 °. The second receptacles B for workpieces of the second type are arranged offset on the turntable 1 to the first receptacles A by the configuration angle K. The turntable 1 allows all recordings A, B to rotate in a single configuration step by the configuration angle K.

As a result, the turntable 1 shown in FIG. 6 is obtained, in which, in operation, the second receptacles B are in each case assigned to the operator 26 and to the first production unit F1 and F1 be supplied to the second production unit F2. The configuration state of the turntable 1 shown in FIG. 6 is functionally identical to the turntable shown in FIG. The first manufacturing unit F1 and the second manufacturing unit F2 are optionally configurable for machining the workpieces of the first type or the workpieces of the second type. The necessary reconfiguration takes place in the course of the single configuration step or in addition to this. For example, the configured according to Figure 5

Turntable 1 in working mode in a first phase of operation equipped with workpieces of the first type and rotated by the pitch angle T, the production units Fl and F2 edit the workpieces of the first type in a two-stage joining process. After the operator 26 has processed in this way a predetermined number of workpieces of the first type, the turntable 1 is rotated by the configuration angle K in the single configuration step. For this purpose, for example, a screw is released, which is located in a radial slot in an upper part of the turntable 1. Then, the upper part of the turntable 1 is rotated by the configuration angle K. Subsequently, the screw is tightened in the radial slot again, whereby the upper part is locked against a lower part of the turntable 1 again.

In addition, the production units F1, F2 are reconfigured. The turntable 1 according to FIG. 6 is then equipped with workpieces of the second type in a second operating phase and rotated by the pitch angle T, with the recordings A, B being offset by the configuration angle K compared with the configuration from FIG Manufacturing units Fl, F2 edit the workpieces of the second type.

In particular, it is also possible to workpieces of the first type by the operation in the first phase of operation Assemble workpieces of the second type. After the operator 26, for example, has produced 1000 workpieces of the second type in the first operating phase, the turntable 1 is reconfigured to continue the operation of the turntable 1 in the second operating phase and to further process the workpieces of the second type.

Figure 7 shows a turntable 1, which is also divided with a pitch angle T of 120 ° in three circular sectors as segments. Again, the integer factor is 2, by which the pitch on the turntable 1 is divided into a configuration pitch with a configuration angle of 60 °. The turntable 1 of Figure 7 allows a one-step joining process, since each workpiece per revolution about the turntable 1 only one production unit Fl, F2 is supplied. Each workpiece is processed with two revolutions around the turntable 1. For this purpose, the turntable 1 has first recordings AI, A2 for receiving a plurality of workpieces of a first group in mutually adjacent relative positions, each offset by the pitch angle T for each

Segment are arranged on the turntable 1. Furthermore, on the turntable to the first recordings AI, A2 offset by the configuration angle K second recordings Bl, B2 set up for receiving a plurality of workpieces of a second group in zueinan- adjacent adjacent relative positions. The first recordings AI, A2 are a first left record AI and a first right record A2. Correspondingly, the second recordings Bl, B2 are a second left record Bl and a second right record B2. In this case, the first left-hand receptacle AI can be executed separately from the first right-hand receptacle A2 or be formed integrally therewith. The same applies to the second recordings Bl, B2. The turntable 1 is fitted in working operation in a first phase of operation with workpieces of the first group in the first recordings AI, A2 and rotated by the pitch angle T, wherein the first production unit Fl in the first lin- Ke record AI inserted workpieces of the first group and the second manufacturing unit F2 processed in the first right receiving A2 inserted workpieces of the first group. After a certain time, the work operation is terminated, whereupon all recordings AI, A2, B1, B2 are rotated by the configuration angle K in a single configuration step.

For this purpose, for example, a screw is released, which is located in a radial slot in an upper part of the turntable 1. Then, the upper part of the turntable 1 is rotated by the configuration angle K. Subsequently, the screw is tightened in the radial slot again, whereby the upper part is locked against a lower part of the turntable 1 again. The upper and lower parts are each formed, for example, as round plates or plates.

In addition, the production units F1, F2 are reconfigured for processing workpieces of the second group. Subsequently, the turntable 1 is fitted during operation in a second phase of operation with workpieces of the second group, which are used in the second record Bl, B2, and rotated by the pitch angle T. In this case, all images AI, A2, B1, B2 are positioned offset by the configuration angle K, with the second images Bl, B2 coming to lie in front of the production units F1, F2 in each case. In this case, the first production unit F1 processes workpieces of the second group inserted into the second left holder Bl and the second production unit F2 processes workpieces of the second group which are inserted into the second right holder B2.

FIG. 7 shows the first configuration state of the turntable 1 for processing the first workpiece group. After each rotation, the operator 26 removes a workpiece of the first group from the first left shot AI facing it. Then, the operator 26 removes a workpiece from the first right-hand receptacle A2 facing it and sets it in the first left shot AI facing him. Subsequently, the operator 26 inserts a new workpiece of the first group into the first right-hand receptacle A2 facing it. In conclusion, the operator 26 initiates a rotation of the turntable 1. Parallel to the manual actions of the operator 26, the first production unit F1 processes a workpiece in the first left holder AI positioned in front of it and the second production unit F2 processes a workpiece in the first positioned in front of it right shot A2. The process efficiency is significantly increased because during the operator's manual operations 26 two machine operations are performed in parallel.

There are two relative positions of the first images AI, A2 (and also of the second images B1, B2): right and left. Corresponding to the number of relative positions or the number of actively used receptacles per segment, a workpiece of the first group requires two revolutions on the turntable 1 until it is completely processed on the mounting system.

FIG. 8 shows an example of the use of a circular tilt table with a turntable 1. This example shows a hybrid mounting system 13 with a turntable 1, which is manually triggered and can be set in a rotary motion. For transport and indexing of components, this turntable 1 serves as a means of transport and interacts with an indexing unit. The turntable 1 shown in Figure 8 is listed as a rotatable support plate to accommodate components. Furthermore, storage and freewheel 2 are outlined. Cam rollers 3 are partially visible. The overall view shows, in addition to the workstation of an operator 26, a first production unit F1 and a second production unit F2, which are integrated in the mounting system 13, which in turn can be connected in series several times in succession. The turntable 1 shown in Figure 8 is equipped with three cam rollers 3. The turntable 1 is thus divided with a pitch angle of 120 ° in three circular sectors as segments. The limits of the circular sectors result, for example, from the positions of the cam rollers 3. The operator 26 inserts workpieces 14 into a first left receptacle AI and a first right receptacle A2 on each boundary between the three segments of the turntable 1 and guides them by rotation of the turntable 1 of the first production unit Fl and the second production unit F2, which are, for example, automated soldering or welding stations. In this case, the mounting system 13 is set up such that the first production unit F1 accesses the workpiece 14 in the first left holder AI and the second production unit F2 accesses the workpiece 14 in the first right holder A2.

Although not all elements of FIG. 7 are shown in FIG. 8, the turntable 1 of FIG. 8 is identical to the turntable shown in FIG. 7 in terms of features and function, so that the description of FIG. 7 is to be used in the same way for FIG ,

Figure 9 shows a mounting system 13 with a turntable 1, which is divided with a pitch angle of 120 ° in three circular sectors as segments. According to a first configuration, respective first receptacles A are fed to a first production unit F1 and to a second production unit F2 in a two-stage joining process. After reconfiguration of the turntable 1, wherein all recordings A, B by one

Configuration angle of 60 ° are rotated, an operation of the turntable 1 according to a second configuration is possible in which the second images B are each an operator and the first production unit Fl and the second manufacturing unit F2 supplied. Furthermore, the turntable 1 shown in Figure 9 is identical in equipment and function to the turntable 1 shown in Figures 5 and 6, so that the Description of the figures 5 and 6 in the same way for Figure 9 is to be used.

Figure 10 shows a section through a reconfigurable turntable 1. A lower part 32 of the turntable 1 is mounted with a bearing and a freewheel 2 and equipped with cam rollers 3, which are captured by an indexing unit 8 and centered. On the lower part 32 is an upper part 31, for example, a plate whose diameter corresponds to that of the lower part 32 or exceeds this, as shown in Figure 10. The upper part 31 is rotatable relative to the lower part 32.

In the upper part 31 extends a slot 33, which is shown in Figure 10 in cross section. A pin 34 is firmly pressed into the lower part 32 and protrudes into the slot 33, so that the upper part 31 abuts against the lower part 32 after rotation with the respective end of the slot 33 on the pin 34.
