Abstract

In order to optimize the performance of rotary fixed-cycle assembly systems, a circular indexing table is loaded with a plurality of workpieces, thus making it possible to adjust the assembly systems to variable process times for manual and mechanical operations. Since a plurality of workpieces is assembled in each segment, a plurality of mechanical operations can be performed in parallel with manual operations even in a one-stage joining process, thus significantly increasing process efficiency. Furthermore, functional flexibility is considerably increased because even in a one-stage joining process, different production units can access the rotary table simultaneously, a dedicated workpiece holder or the relative position thereof being assigned to each production unit. The rotary table 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. As the workpiece holders are loaded with a plurality of workpieces and a plurality of workpiece holders is arranged in each segment, production units can be used in a more flexible manner and the number of passes of the workpieces can be increased by transferring the workpieces to an adjacent workpiece holder in the same segment after each pass. Moreover, the extent and thus also the duration of manual operations can be managed in a significantly more flexible manner, making it possible to synchronize manual and mechanical operations to a high degree and render the whole process 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. 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 in the assembly of component systems which are accomplished on turntables, a comprehensive control of these operations in terms of 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 An indexing unit is usually taken up, damped and centered on a cam roller at a certain pitch corresponding to a corresponding machining. 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 further rotation by one pitch followed by re-positioning of the following cam roller. 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.

It has as its object to provide a turntable, a Kreisteiltisch, a mounting system and an operating method thereof, which increase the efficiency of manufacturing.

This object is achieved by a turntable for receiving, transporting and fixing workpieces, in which a division is predetermined on the turntable, which divides this into equal segments, and wherein the turntable is in particular circular and the segments in particular

Circular sectors are. The turntable is rotatable by a respective angle of rotation, which is predetermined by the pitch on the turntable. The turntable is characterized in that for each segment on the turntable workpiece carriers are arranged for receiving a plurality of workpieces in mutually adjacent relative positions. There is thus provided a multiple occupancy of the segments of circular tilt tables. This is achieved for example by several separate workpiece carrier, which are mounted side by side on each segment of the turntable (or at the transitions between see the segments). Alternatively, a workpiece carrier with multiple occupancy is used, ie a continuous component which can be equipped with different workpieces at the same time. Furthermore, the workpiece carrier can also be part of the turntable or made of a cast with this.

The advantages mentioned below need not necessarily be achieved by the subject-matter of the independent patent claims. Rather, these may also be advantages that are achieved only by individual embodiments, variants or developments.

The fact that more workpieces per segment can be used on the turntable, a power adjustment in round-clocked mounting systems is made possible, since now can be adapted to different process times manual and mechanical operations. By assembling several workpieces per segment, even in a one-step joining process, several mechanical operations can be performed in parallel to the manual operations, which significantly increases process efficiency. Furthermore, the functional flexibility is increased considerably, since now also in a single-stage joining process different production units can access the turntable at the same time by assigning a separate workpiece carrier or its relative position to each production unit. In this case, one-stage means that only one mechanical operation is performed on each workpiece during one revolution at the circular table.

The turntable thus opens up a new combinatorial potential of Kreisteiltischen in rotary indexing machines, which meets the requirements for increased flexibility in the context of a "Design for Flexibility" and "Plug &Produce". Due to the multiple occupancy or multiple arrangement of the workpiece carrier per segment not only manufacturing units can use more flexible, but also increase the number of revolutions of the workpieces by these are transferred after each cycle in an adjacent workpiece carrier on the same segment. Furthermore, the contents and consequently the duration of the manual operations can now be made much more flexible, which enables a high degree of synchronization of manual and mechanical work in terms of process efficiency.

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 Kreisteiltisch includes at least one indexing unit for automatically receiving and centering the at least one cam roller. The pitch on the turntable is predetermined by the arrangement of the at least one cam roller. The at least one cam roller 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. 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 support plate in the strict sense, but are directly required for its attachment, management and operation. For the entirety of this device, the term circular table is generally used.

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 on the surface in workpiece carriers (receiving units) 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 or the circular dividing table. It also comprises a plurality of production units, in particular welding units, Lotbandvorschüben and / or drilling units. These and the workpiece carriers are arranged such that there is a clear association between the relative positions of the workpiece carriers and the production units. Each production unit is set up to process a workpiece inserted into its relative position after each rotation of the turntable.

The assembly of components and their assembly can be advantageous by the use of a turntable in

Connection with multiple manufacturing units, which together form a mounting system, are performed. Manual and automated processes are mixed. According to one embodiment of the mounting system, this comprises a first production unit which is set up to machine a workpiece inserted in a workpiece holder arranged on the right. It also comprises a third production unit, which is set up to machine a workpiece inserted into a left-hand workpiece carrier. Optionally, it also comprises a second production unit, which is set up to machine a workpiece inserted in a centrally arranged workpiece carrier. Of course, further workpiece carriers and production units can be provided in an analogous manner.

In the method for operating the turntable, the circular dividing table or the mounting system, the turntable is rotated by a rotation angle which is predetermined by the pitch on the turntable. A workpiece is removed from a left-hand workpiece carrier. A workpiece is removed from a right-hand workpiece carrier. A workpiece is inserted into the workpiece carrier on the left. A workpiece is inserted into the right-hand workpiece carrier. These operations are done manually or by machine, for example by a robotic arm. The turntable is then rotated again by the angle of rotation, which is determined by the pitch on the turntable.

In a further development of the method, the workpiece, which is arranged on the right-hand side of the workpiece carrier, is inserted into the workpiece carrier arranged on the left.

Alternatively, a workpiece is removed from a centrally located workpiece carrier and inserted into the workpiece carrier arranged on the left, and the workpiece removed from the workpiece carrier arranged on the right is inserted into the centrally arranged workpiece carrier. According to one embodiment of the method, after each rotation of the turntable and temporally parallel, a first production unit processes a workpiece inserted into a workpiece carrier arranged on the right and a third production unit processes a workpiece inserted into a workpiece carrier arranged on the left. Optionally, a second production unit also processes a workpiece inserted into a centrally arranged workpiece carrier. In one development of the method, a workpiece is first inserted into the workpiece carrier arranged on the right. The workpiece is fed during each revolution of the turntable of another manufacturing unit and processed by this. After each full revolution of the turntable, the workpiece is folded into the left hand nearest lying relative position, in particular the centrally arranged workpiece carrier or the left-hand workpiece carrier. Finally, the workpiece is removed from the left-hand workpiece carrier.

The turntable or the Kreisteiltisch can 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,

2 shows the top view of a circular tilt table with turntable 1, storage and freewheel 2 and Indexierein- 8 with a cam roller 3 positioned therein, wherein the turntable 1 is shown completely and transparently, FIG. 3 shows an example of a hybrid mounting system 13 with a variably indexable turntable 1, which after further rotation is decelerated and centered again by a pitch, a mounting system 13 the segment per turntable 1 exactly one workpiece on the Drehtel ler is used, and two temporal processes associated manual and mechanical process steps, a mounting system 13, in which per segment of a turntable 1 exactly two workpieces on the turntable 1 are used, and a temporal From associated manual and mechanical process steps,

6 shows a mounting system 13, in which per segment of a

Turntable 1 exactly three workpieces on the turntable 1 can be used, as well as a temporal sequence of associated manual and mechanical process steps.

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 is a turntable 1 and a Kreisteiltisch on which workpieces are inserted into the workpiece carrier. The turntable 1 is then rotated by an operator 26 in the arrow direction in a clockwise direction, whereby the inserted workpiece successively different production units, which are mounted on the operator 26 opposite the production carrier modules 21, respectively. For example, a soldering of two workpieces by a first production unit 221, to which a second production unit 222 fully automatically feeds a soldering tape. Furthermore, Figure 1 shows arrows on the left and right

Operator's side 26. These indicate that the operator 26 is picking up workpieces from the left for processing and passing them to the right. As can be seen in FIG. 1, the operator 26 in each case accesses production units via the turntable 1, which units are not located on the production carrier module 21 on which the operator 26 stands. Rather, the operator 26 can operate the production units on the production carrier modules 21 opposite thereto by means of the turntable 1. The working radius of the operator 26 is thereby significantly increased. The turntable 1 in this case forms in connection with the surrounding six production carrier modules 21 and the production units 221, 222, 223, the mounting system 13. The turntable 1 shown in the following figures, which at a determinable time in a rotational movement, here simultaneously a transport movement is in the final position of the rotational movement, d. H. if he has rotated by one pitch, automatically fixed. After the rotation, for example, further manual or automatic welding or soldering, bending or similar processes can be started.

Figure 2 shows a Kreisteiltisch with a turntable 1 in a sectional side view in detail, are distributed on the cam rollers 3 in a predetermined pitch over the circumference. FIG. 2 also shows a bearing and a freewheel 2, a centering element 5 and an indexing unit 8 and a common carrier 11. In the operating state illustrated in FIG. 2, the cam roller 3, which is inserted into the

Indexing unit 8 is retracted, not centered by the centering element 5 and fixed. This is the cylinder 6th retracted and has the centering element 5 in the position shown offset relative to the turntable 1 radially outward.

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.

It is clearly visible in FIG. 2 that neither the stop 4 nor the centering element 5 obstruct the path of the cam roller 3 within the indexing unit 8. Thus, by an actuating handle 10, the triggering or initiation of a

Rotary movement of the turntable 1 are retrieved. If this rotational movement is triggered, the turntable 1 continues to rotate by one pitch, so that the next cam roller 3 moves into 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 frictional connection between stop 4 and cam roller 3 can be released. The turntable 1 rotates by one pitch and the stop 4 receives the next cam roller 3, which 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 8 and the cam rollers 3 on the turntable 1, the turntable 1 is automatically depending on the division or depending on the position of the workpiece carrier, which are located on the turntable 1, captured in the indexing 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.

FIG. 3 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 3 is designed 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 next to the workplace of an operator 26, a first production unit 221 and a second production unit 222, 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 3 is equipped with three cam rollers 3. The division on the turntable is 120 °, resulting 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 sets working means 14 in a left-hand workpiece carrier 201 and a right-hand workpiece carrier 203 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 221 and the second manufacturing unit 222, 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 221 accesses the workpiece 14 in the workpiece carrier 201 arranged on the left and the second production unit 222 accesses the workpiece 14 in the workpiece carrier 203 arranged on the right.

Figure 4 shows a round-clocked mounting system 13. A turntable 1 of a Kreisteiltisches is divided into three segments or circular sectors, each covering an angle of 120 °. An operator 26 places a workpiece in a centrally arranged workpiece carrier 202 facing it which, after rotation of the turntable 1, is positioned in front of a first production unit 221.

FIG. 4 also shows a time sequence for a single-stage joining process according to a first case 41. In this case, the operator 26 removes a workpiece from the center-facing workpiece carrier 202 facing it in a depositing step 31. Subsequently, the operator 26 inserts a new workpiece in an inserting step 33 the centrally arranged workpiece carrier 202 a. This is followed by a rotation 34 of the turntable 1. Parallel to the depositing step 31, the first production unit 221 begins a first operation 51, which comes to a conclusion somewhat faster than the insertion step 33. In the second case 42, the first operation 51 is completed only after the insertion step 33.

FIG. 5 shows the round-clocked hybrid mounting system 13 from FIG. 3 in a schematic plan view. The turntable 1 of Kreisteiltisches is clearly visible divided into three segments or circular sectors, each covering an angle of 120 °. Workpieces which are inserted into the workpiece carrier 203 arranged on the right are positioned after rotation of the turntable 1 in front of the first production unit 221. Correspondingly, workpieces 201 in the left-hand arranged workpiece carrier 201 come to lie after rotation of the turntable 1 in front of the second production unit 222. FIG. 5 also shows a time sequence for a one-step joining process with the mounting system 13. In this case, the operator 26 removes a workpiece from the workpiece carrier 201 arranged on the left in a depositing step 31. The operator 26 then removes a workpiece in a reversing step 32 the workpiece carrier 203 arranged on the right-hand side and inserts this into the workpiece carrier 201 arranged on the left-hand side facing it. Subsequently, in an insertion step 33, the operator 26 inserts a new workpiece into the workpiece carrier 203 arranged on the right-hand side thereof. This is followed by a rotation 34 of the turntable 1. Parallel to the depositing step 31, the first production unit 221 starts a first operation 51 and the second production unit 222 a second operation 52, both of which come to a conclusion somewhat faster than the insertion step 33. Compared to the example shown in FIG. 4, the process efficiency is thus significantly increased since two mechanical operations are carried out in parallel during the manual operations. There are two relative positions for the workpiece carriers: right and left. According to the number of relative positions or the number of workpiece carriers per segment, a workpiece requires two revolutions on the turntable until it is completely processed on the mounting system 13.

FIG. 6 shows a further round-clocked hybrid assembly system 13 in a schematic plan view. A turntable 1 of a circular tilt table is here divided into six segments or circular Sectors are divided, each covering an angle of 60 °. Workpieces which are inserted into a workpiece carrier 203 arranged on the right are positioned after rotation of the turntable 1 in front of a first production unit 221. Correspondingly, workpieces come to lie in a centrally arranged workpiece carrier 202 after rotation of the turntable 1 in front of a second production unit 222. Furthermore, workpieces 201 come to lie in a left-hand workpiece carrier 201 after rotation of the turntable 1 in front of a third production unit 223.

FIG. 5 also shows a time sequence for a single-stage joining process with the mounting system 13. In this case, an operator 26 removes a workpiece from the workpiece carrier 201 arranged on the left in a depositing step 31. The operator 26 then removes a workpiece in a reloading step 32 from the center-facing workpiece carrier 202 facing it and places it in the workpiece carrier 201 arranged on the left-hand side facing it. In the same step, the operator 26 removes a workpiece in a relocation step 32 from the workpiece carrier 203 arranged on the right-hand side thereof and inserts it into the centrally arranged workpiece carrier 202 facing it. Subsequently, in an insertion step 33, the operator 26 inserts a new workpiece into the workpiece carrier 203 arranged on the right. The first production unit 221 begins a first operation 51, the second production unit 222 a second operation 52 and the third production unit 223 a third operation 53, which come faster than the insertion step 33 to completion , Compared with the examples shown in FIGS. 4 and 5, the process efficiency is significantly increased because during the manual operations three machine operations are performed in parallel.

There are three relative positions for the workpiece carriers: right, center and left. According to the number of Relative positions or the number of workpiece carriers per segment requires a workpiece three revolutions on the turntable until it is completely processed on the mounting system 13. The described embodiments, developments and embodiments can be freely combined with each other.
