Description

 Production plant and its parts

The invention relates to a production plant comprising a

 Production rack with four vertical feet enclosing a rectangle. The invention further relates to a workstation, in particular for use in a production plant or production line. Furthermore, the invention relates to a disc spool magazine, in particular for a workstation, in particular for use in a production line or production line, comprising a holder for a plurality of adjacently arranged disc spools for rolling up delivered in a blister strip items. Furthermore, the invention relates to a method for producing at least approximately rotationally symmetrical assembly parts made of several individual parts as well as an assembly component produced therewith.

DE 197 41 671 B4 describes a production plant which is composed of several workstations, wherein the workstation has a body which can be carried on a trolley, wherein several of the workstations in the production plant can be arranged along a conveyor belt. A disadvantage of the known production plant or the known workstations is the fact that they must always group along a conveyor belt, and that the workstations here form part of the production line or the production line, so that when replacing the workstation is the respective production plant. With each conversion, it is necessary to completely rebuild the production line or the production line, whereby the work stations within the production line form modules that are then transferred to another

Order can be recycled. The conveyor belt has, among other things, the disadvantage that round parts due to vibrations and / or

 Mass inertia does not remain lying and so against each other and possibly. Damaged.

CONFIRMATION COPY From practice, workstations are known which are used in a production plant for the production of printed circuit boards in which the

Workstation a disc spool magazine is connected, in which a plurality of adjacently arranged disc coils are provided in a holder, on each of which a blister with delivered

 Individual parts, in particular electronic and electrical components that are to be mounted on a circuit board, is provided. Here are the

Conductor tracks along a conveyor path, for example, arranged on a conveyor belt, usually formed as an endless large circuit board, and a handling apparatus populates the circuit boards with the delivered

Items. The disadvantage here is that the production plant must have a conveyor for the contiguous large or individual small circuit boards, and that the production only works as long as the promotion of printed circuit boards works.

It is the object of the invention, a production plant or a

Workstation or a disc spool magazine or a method for producing at least approximately rotationally symmetrical

Specify assembly parts of several items that have a great deal of flexibility.

Furthermore, according to the invention, the line creation time is to be reduced to release, as well as the production production time and especially the set-up time. The required space requirement should remain low and

Cleanliness-related quality issues are eliminated as much as possible.

This object is achieved by a production plant or a workstation or a disc coil magazine or a method for producing at least approximately rotationally symmetrical assembly components according to the features of an independent claim.

According to one aspect of the invention, there is provided a production facility comprising a production rack with four enclosing a rectangle vertical feet or uprights, wherein two pairs of the four feet are interconnected at their upper end with an upper horizontal cross member, the two pairs of the four feet spaced from the upper horizontal cross member and from a lower end of the feet with a lower horizontal cross member are interconnected, wherein the two cross members are connected to each other by two mutually parallel and perpendicular to the horizontal cross members longitudinal beams. In this way, a production plant is advantageously provided which has in the region which is enclosed by the vertical feet, two recessed indentations, can be used in the workstations, the workstations are advantageously interchangeable. It is possible that the two side members are each still connected to each other with a cover in the manner of a work table, or that on the upper cross members or side rails power supply facilities such as compressed air or electricity or

Refrigeration units are positioned. These are then usually connected to the machines connected to the upper side members or handling equipment. Similarly, below the lower side rail a

Energy supply, so at least one provided with electrical voltage and / or compressed air, which can be fed to the workplaces.

Conveniently, the production frame is made of steel, and has, for example, side members, cross members and feet with a rectangular profile or with a square cross-section, so that the production frame as a whole has a high rigidity and stability. Conveniently, at the lower ends of the feet are still adjustable, that is adjustable in height, screw-provided spacers provided, which it also

make it possible to align the production rack exactly plan position and to compensate for any unevenness of the floor. Conveniently, at least one workstation can be suspended on at least one of the two lower longitudinal members. In general, at least two workstations will be suspended or connectable on both sides of the lower side members, so that the production plant with several Connected to workstations that are loading or unloading

Entladestationen or workstations can act in the true sense of the word, namely those in which a transformation or a

Processing of a workpiece by a machine or a test by a test device is done.

Conveniently, the workstation or arranged thereon

Machine or equipment selected from the group comprising a component feeder, a pressing station, a laser welding station, a concentric optical mixing station, a sealing ring joining station, a

 Leak test station, a functional test station and an ultrasonic welding station. It is understood that more than one of the mentioned stations can be connected to the production plant, for example, if the

Production plant is not used for a sorted operation, but for a mixed operation.

Preferably, the two mutually parallel cross member connecting longitudinal members are arranged in a common horizontal plane. Alternatively, the two side members may also be arranged in different horizontal planes, for example one above the other. Here, the two side members are preferably spaced from each other by a gap, so that each of the two side members can be encompassed by an attachment. Instead of a gap but other openings may be provided, such as holes or slots.

Preferably, at least one handling device can be connected to at least one of the two upper side members. It is possible that the handling device is connected to both upper side members, in particular in the gap between the two upper side members is fixed - usually the handling device or the

Handling device to be connected to an outwardly facing side of an upper side member. The handling device is used here, items, intermediates or end products of the Work stations or deliver to the workstations, the workstations as a buffer or buffer at the

Production plant itself can be provided. In this case, the handling facilities also take over the promotion of the intermediate product or the final product, so that a belt conveyor that is pollution intensive and affects the accuracy of provided on the production plant assembly and forming equipment can be omitted. Consequently, the production in the production plant and the promotion in the production plant is the same sequence of movements.

The extent in the direction of the side members of the production plant is suitably greater than their extension in the direction of the cross member. As a result, a rectangular profile in plan view is provided that provides two indentations in which the workstations can be received by the provided in a central region of the longitudinal beam provided in the production plant.

Preferably, a workpiece holder can be connected to the lower longitudinal members, which makes it possible that of several individual parts, the

For example, be taken from a disc spool magazine, an assembly part can be made without this

Handling device must hold the parts themselves.

Appropriately, below the lower side rail and / or above the upper side rail a power supply and / or a

Plant control arranged. The plant control is sent to the

Workstation control connected to the workstations and there loads instructions on how the workstations have to process. It is possible from a plurality of in the direction of the longitudinal member

arranged in series one after another production line (or production line) along which, however, no conveyor belt or the like runs, but that essentially a road in the sense forms that along this road from the individual parts on the intermediate product to the final product and the final product tests, the various steps can be performed automatically in succession, and at low cycle times. As a result, the production line is very flexible, since their production plants remain arranged one behind the other, even when the production line is being serviced or retrofitted for another product to be produced. It is even possible to simply skip unused workstations on a less complex production without degrading them. As a result, a production line is created in which no conveyor belt runs in the direction of the side members, and also does not have to be readjusted each time and must be removed by the customer when switching to another end product. Thus, it is advantageously possible to provide a production line that is equipped for the production of a plurality of products, depending on the utilization of different products along the production line can be made without the production line must be set again, calibrated and removed in case of changes in the product , Appropriately, the transfer of products takes place in the direction of the longitudinal members without the use of a conveyor belt; this means that the products or components are essentially made up of handling equipment only

Handling device to be handed over, either directly or with the interposition of at least one workpiece holder. As a result, a continuous flow of products is achieved that does not depend on a conveyor belt, so neither the setting of a continuous conveyor speed requires nor a permanent start and deceleration. It is possible that a conveyor belt is provided exclusively transversely to the longitudinal members.

In accordance with one aspect of the invention, there is provided a production facility on which various assemblies can be made comprising at least one handling system equipped with a gripping system, each assembly being associated with at least one specific workpiece fixture and / or tool Workpiece mounts of several different modules are arranged in a row and wherein the row is designed to be displaceable in order to move the workpiece assembly associated with the selected assembly to the relevant point for the operation. This advantageously achieves that several products can be produced on the same production line, and if the product line is, for example, homologated by the customer, it does not have to be disassembled if another product is to be produced on the production line. Rather, they are

Workpiece holders for the handling apparatus or their

Gripping systems arranged optimal positions, or on the

 Work stations arranged, and depending on which module is to be produced, the associated workpiece holders or

associated tools to the selected deployment position spent.

As a result, it is not necessary, individual tool devices before

Commissioning, but the production line is permanently homologated for each individual assembly. Moreover, a particularly simple conversion is possible because the handling devices or their gripping systems can make the shift of the series in response to a corresponding command of the controller itself. As a result, can be retrofitted in a very short time during operation to a new assembly, without requiring manual parts of the production line would have to be replaced.

Conveniently, the series is on a common support

arranged so that all workholding containers are moved together when the support is moved. Moving a support is less risky than moving a loose row, because the support can only move in one direction or the other. The support is thus equipped with a longitudinal guide, which also carries all workholding containers.

According to a favorable variant, the row is moved by the handling apparatus, so that no separate drives for moving the row or the support required. Preferably, however, the series has its own drive, with which the row can be moved. This own drive can then be controlled in a change in production to the effect that the row is changed in position so that the appropriate and homologated workpiece holder is used. It is possible to monitor the correct position with a sensor.

Appropriately, a system control is provided, which automatically adapts the workpiece holders when retrofitting to another product.

This advantageously achieves that an input sequence of the

 Plant control already causes the conversion of the production line. In addition, when restarting or cold-starting, auto-tuning will not accidentally produce a wrong part or with the wrong part pickups.

The workpiece holder is expediently at a pre-assembly station, a machine or at a transfer station between two

Handling devices arranged, and takes up items that are stacked in one another. By depositing in a transfer station, the handling devices or their gripping systems can work quickly because they do not have to hold individual parts on their gripping system longer, so that a short cycle time is achieved.

Alternatively, the workpiece holder on a pressing tool, in which the semi-finished product is inserted as a workpiece and formed or further processed. The plant control then ensures that the tool, for example the pressing tool, is reshaped with the pressing force required for the corresponding assembly. In most cases, it is driven on a production plant sorted, that is, it is at the same time always produced the same assembly, so that the specific parts for the assembly are provided in a disc spool magazine and then on pre-assembly, forming and Final assembly, an assembly in an end product output, for example, a so-called tray can be stored. However, it is alternatively possible for at least two different assemblies or more than two assemblies to be produced simultaneously, in particular if the production plant or production line is sufficiently long. For example, one production line may contain several production plants and several

Have inputs on which either the same assembly is produced twice, or in which two disc spool magazines with different parts two different end products are produced.

Conveniently, the blister straps that provide the individual parts of an assembly on the disc spool magazines are inserted into a delivery assembly that lifts and removes a cover sheet from the blister strip

Removal of the item from a suitably trained cavity then cuts off the empty supernatant of Blistergurts and crushed, for example, for recycling. The feeder arrangement ensures that the blister straps are correctly inserted and the items contained therein are fed correctly. It is possible to carry out a first optical quality control in the area of the feed arrangement.

According to one aspect of the invention, a work station is provided, in particular for use in a production plant or production line as explained above, comprising a body with a projecting cantilever region, wherein the cantilever region is designed to be hooked into a production plant. The cantilever allows the workstation to be used, for example, for purposes of maintenance or repair

Production plant can be replaced, or can be connected to the production plant. The connection is in this case such that the workstation is stored on a trolley or pallet truck, which is adjustable in height, so that the workstation is moved to a raised position, in which the projecting Kragbereich a lower

Longitudinal beam of the production plant towers above and by lowering the Transport trolley is connected to the lower side member of the production plant. Here, the workstation no longer touches the ground, so that the plane orientation of the production line for the

Workstation without special adjustment work is achieved. By the

Overlapping of cantilever and side member will be a stable and

created small-scale connection, and the workstation can be compactly realized.

Appropriately, the Kragbereich for this purpose has two downwardly facing centering, which are countersunk into a corresponding bore of the longitudinal member, with further holes can be used on the Kragbereich and on the longitudinal members for screwing the two parts.

Preferably, perpendicular to the Kragbereich a Kragbereich limiting vertical end wall is arranged, which also forms an abutment. If the cantilever area over the entire surface resting on the longitudinal member and the end wall is located on the suitably equipped with a rectangular cross-section of longitudinal members and thus prevents unwanted

Bending the workstation. But it is possible that the end wall is spaced from the side rail, such as when a flat

Liner is provided.

If the workstation is connected to the production line, the trolley or pallet truck can be lowered further and pulled away below the workstation so that the workstations for the production of end products can also be accessed by operators.

Conveniently, the end wall has an opening for a

Power supply such as electrical power supply and compressed air, so that the power supply through the opening can be fed to a control cabinet of the workstation. As a result, it is not necessary to provide the workstation separately with energy, the corresponding power supply lines pose a risk of tripping for operators would.

Conveniently, the body has a side wall, at the one

Control cabinet is connected by means of a guide. The side wall is substantially perpendicular to the end wall and to the Kragbereich or a work table, which is arranged at least parallel to the Kragbereich provided. Are several workstations to each other at one

Provided a production line, closes the side wall of the adjacent workstation access to the cabinet so that the connection of the cabinet to the side wall by means of a guide advantageously allows the cabinet can be pulled out, for example, for inspection purposes, without the workstation for the production plant must be solved. The guide is preferably designed as a telescopic roller guide with two guide rails, wherein the two guide rails

are arranged one above the other and parallel to each other. This makes it advantageously possible to pull the cabinet with little effort from a stowed in an extended position and push back into it. Thus, adjacent workstations can also be arranged close together, and the respective cabinets remain accessible. Expediently, an emergency stop switch is then provided on an end face on which, for example, a handle for pulling out the control cabinet is located. It is possible in the fully extended and / or fully retracted position of the

Provide a lock of the guide cabinet to prevent unwanted movement.

In this case, an access to the control cabinet is preferably arranged on a side opposite the guide rails, so that when the control cabinet is completely pulled out, which by correspondingly long enough telescopic roller guides, as for example for connecting drawers of dishwashers or furniture already in use, can be easily achieved that the access can be opened completely and not just a crack.

The body expediently has a working surface on which a machine can be arranged, for example a pressing machine or a laser welding machine. The associated control is then housed in the above-explained cabinet, with individual

Tools or tool groups of the machine can also be arranged on the work surface or the Kragbereich.

In plan view, the body expediently has a rectangular basic shape, wherein the Kragbereich is arranged on a narrow side of the rectangular basic shape. This arrangement is particularly space-saving and is sufficient to achieve a stable and substantially torsion-resistant connection of the workstation to the production plant. It is possible, however, too

 To connect workstations to the production plant, the Kragbereich is arranged on a broad side of the rectangular basic shape. In this case, it is not absolutely necessary to use a

Roller guide to connect to the body, since the access exhibiting broadside of the cabinet then also facing the operator

can be arranged.

The body expediently consists of several together

connected steel plates, which in particular can be screwed or welded together, so that the body has a high rigidity and does not tend to kralkl mounting on the side member of the production plant to a tolerance of the product to be produced impairing vibration or twisting. According to one aspect of the invention, a disc spool magazine

created, in particular for an aforementioned workstation or for use in an aforementioned production plant or production line, comprising a holder of a plurality of juxtaposed Disc coils for rolling up delivered in a blister belt

Individual parts, wherein the disc coils each have two side discs with circular circumference, which define a tubular core frontally, wherein the holder has two at least one disc coil radially supporting support cylinder on which the at least one

 Disc coil is supported. In this way, a disc spool magazine is advantageously created that can also deliver comparatively heavy parts in blister straps, without the high weight of the individual disc spools or their wound blister straps inhibiting unrolling from the holder. While in the prior art, the disc coils rest substantially on a base of the bracket, the support with two support cylinders allows safe and reliable radial guidance of the

Disc coil, whereby a possible stick-slip effect is avoided and the holder is not damaged by the relative movement of the disc coils. The disc coil is essentially on the two

 Placed support cylinders, in which the weight forces of the disc coil is introduced substantially vertically.

Conveniently, the two support cylinders not only support one

Disk coil, but a plurality of the disk coils radially, so that a plurality of disk coils can be arranged adjacent to each other in the holder. Unlike in the prior art, where the reliable run by intermediate layers between the facing disks of the

As disk spools are reached, the radial guidance causes each spool to move at its own speed.

Conveniently, the support cylinders have at least one radial

Survey on whose extension in the direction of the axis of the support cylinder is dimensioned such that they can be fitted between two side windows of the at least one disc coils. As a result, the elevations are also supported against the inside of the side windows of the side coil, and also guide them axially, so that the provision by separating layers is not required. Preferably, the support cylinders have as many radial elevations as disc coils can be arranged in the holder, so that all

Disk coils are supported radially on the two support cylinders, but also axially.

The radial protrusions do not necessarily all have the same

Extension or width in the direction of the axis of the support cylinder, it is possible different width disc coils on the same bracket

provide, for this purpose expediently the support cylinder can also be modularly composed of individual support cylinder segments, which can be adapted to the specific requirements of the disc coils in the holder.

Conveniently, the radial elevation at its end a radial chamfer, so that the survey does not form a step with sharp edges, but centered with a slant defined by the phase, the discs of the disc coils.

Preferably, the support cylinders are designed as hollow bodies, so that they have a not too high mass. The support cylinders are usually provided as stationary, so non-rotating parts. However, it is also possible to provide rotating support cylinders as an alternative, if the rotational movement of the disk coils is to be supported thereby. Conveniently, the support cylinders are made of steel to experience only a slight deflection under the comparatively high load of a disk coil equipped with individual parts in the blister belt.

The support cylinders are preferably arranged in a bottom region of the holder and have a distance from each other, which makes up at least half the diameter of the side window of the disk coil.

As a result, a particularly reliable support of the disc coil is achieved. Preferably, the holder of the disc spool magazine is mounted on rollers, so that the disc spool magazine can be replaced quickly. For this purpose, a guide handle can be connected to the disc spool magazine further. The change occurs, for example, when at least one of the disc coils is empty, which can happen, for example, that the items contained in the associated Blistergurt were consumed. To avoid being on the individual disc coils

different lengths of blister straps with individual parts remain is

expediently provided that a batch on one

Disc coil magazine or a holder is arranged, is designed for about the same process duration. Alternatively, it is possible to replace the individual disc coils during operation, in which case either two disc spool magazines on the production line

are connected, which provide alternately the supply of individual parts, or the items are redundantly available on the same disc spool magazine, that is, on the same disc spool magazine in each case two disc spools are included with the same items. In order to minimize set-up times, it may be advantageous to allow the production line to operate in which several are at the front

Disc spool magazines is equipped starting.

According to one aspect of the invention, a method for producing at least approximately rotationally symmetrical assembly parts,

In particular, a magnet assembly, created from several individual parts, with the steps of feeding each item in each one on one

Disk reel rolled up blister, and mounting an assembly of the assembly part by sequentially removing and mating the items by means of at least one equipped with a gripping system handling apparatus. As a result, rotationally symmetrical assembly components are created cost-effectively, in an automatic production

arise without requiring manual work steps. Preferably, the mating of the individual parts takes place in one

Workpiece receptacle, which is adapted to an outer housing forming an individual part of the assembly. The housing, the assembly is also fed in a blister strip, so there is no separate feed from

There are housing parts that could make a separate conveyor unit such as a conveyor belt required. The equipped with a gripping system

Handling apparatus takes rather the individual parts of the assembly and arranges them in a meaningful order in a workpiece holder, and thus forms a Vorverbund or an intermediate product that through

Forming, for example pressing, can still be joined into a single unit.

Conveniently, therefore, after the mounting step the

Assembly component in a workstation at least partially reshaped, in particular pressed. This allows the items that are in the

Workpiece holder were plugged together, no longer lost.

Particularly favorable results from this that the displacement of the module or the assembly part is done exclusively by handling equipment and an additional conveyor system, such as a conveyor belt, is not required. This will be accompanied by conveyor belts

Vibration, dust and noise advantageously avoided.

While rotationally symmetric components are difficult to convey via a conveyor belt, they can be handled by different handling devices either by mutual transfer or by transfer in

Workpiece holders are simply passed on, since the angular orientation is of little or no importance here.

The assembly component is expediently designed as an assembly containing electromagnetic means; in particular, the assembly component is selected from the group comprising electromagnets, electromagnetically actuatable actuators, electromagnetically operable valves,

Electromagnetically driven metering pumps, electromotive

Stellsysteme, electric motors and assemblies and magnetic assemblies in particular for the aforementioned assembly components. The mentioned

Assembly components are substantially rotationally symmetrical, almost cylindrical, at least elongated, and therefore can

in particular assembled with the same handling equipment or gripping systems or fed to individual workstations. Also, the processing steps at the workstations are often similar. Furthermore, they form a common product family, which may include other electromagnetically driven parts, which has a similar structural design and partly uses the same components and manufacturing processes. Due to the commonality of the components, according to which the

Assembly contains an electromagnetic means, various related products of this genus can be produced on the same line.

The gripping system of the handling apparatus preferably has at least two grippers, but gripping systems with three are particularly suitable

Grippers, which are arranged rotatably about an axis in the manner of a gripper star. Here, the angle between the grippers with two grippers 180 degrees, with three grippers 120 degrees. It is also possible to provide more than three grippers, for example four, five or six. As a rule, however, three grippers are sufficient, and often even two grippers are sufficient. Preferably, all handling devices or handling devices are the same and / or at least equipped with an equal number of grippers, whereby a production plant can be easily adapted to other components. Preferably, the handling apparatus is designed as a robot system and / or as an axle system, which is particularly preferably connected to upper longitudinal members of a production plant. This allows the gripping systems to intervene in the area of the workstations, the

Handling apparatuses are expediently spaced apart from each other so that they are either directly or via a trained example as a workpiece holder transfer station, the components or

Submit pre-assembly groups. Preferably, one of the parts supplied in the blister straps is one

Housing part, so housing parts do not need to be introduced separately in the production process. Appropriately, handling devices are connected in a production plant to which at least one workstation is connected. As a result, a particularly space-saving arrangement of

achieved interacting parts. Preferably, after at least one method step, an examination of the assembly part is provided so that statistical process control is possible even during production.

The assembly part is preferably a

Magnetic assembly containing at least two and preferably three or four of the following items: a sleeve, an armature, a pole core, and an anchor rod. Such magnet assemblies are part of a plurality of end products, wherein the dimensions of the individual parts vary. It may occasionally happen that identical items in different magnet assemblies are used, for example, the same

Anchor rod.

Conveniently, for example, the sleeve of the first

Handling apparatus taken from the front of a first blister freed from a cover and a first blister in the appropriate cavity

 Workpiece holder used. Then, in the next step, the armature is removed from the frontmost compartment of a second blister which has been removed from a covering film and inserted into the sleeve arranged in the workpiece receptacle, which due to an excess of its rotationally symmetrical inner circumference with respect to the rotationally symmetrical outer circumference of the armature, this armature without applying a force or without previous

Twisting one of the items can pick up; in fact, due to its mass, the anchor easily slides into the sleeve, and the Handling apparatus does not have to apply force for this purpose. Therefore, the use of handling devices is possible, which allow a certain amount of play, for example, in order not to injure them in interaction with operators. In a further step, a handling apparatus picks up an anchor rod from the frontmost compartment of a third blister which has been removed from a cover film and places it in the sleeve in an associated, coaxial bore of the armature, where it lies loosely. In yet another step, a handling apparatus removes a pole core from the frontmost compartment of a third blister which has been removed from a cover film and arranges it in the sleeve above the armature, wherein a central bore of the pole core is penetrated by the anchor rod. The inner circumference of the sleeve may for this purpose have an annular step to the rotationally symmetrical pole core of the armature

spaced to arrange. Since the handling apparatuses have several, for example three, grippers, these steps are preferably carried out partly in parallel: the first one

Handling apparatus sequentially engages with a first and second gripper sleeve and anchor and puts them in the workpiece holder. Almost at the same time. The second handling apparatus engages with a first and second gripper pole core and anchor rod and puts them in the armature-equipped sleeve. Then take the third gripper of the second

Handling apparatus, the sleeve filled with anchor, pole core and anchor rod out of the workpiece holder and puts them, without the items fall out, in a next workstation. In time, the next sleeve is used again in the workpiece holder. It is easily possible, the individual steps differently on the gripper and

Distribute handling devices, e.g. the first and second grippers always hold one or two empty tubes, and while the third gripper of the same handling device removes the filled tube. The other handling apparatus then grips with its three grippers the other three items. It is also possible to use the production plant with only one

Operate handling apparatus. The preassembled magnet assembly is compressed after assembly in a pressing station in that the pole core is pressed against the sleeve. As a result, the armature can no longer escape from the sleeve having a closed bottom relative to the pole core. In further steps, the magnet assembly is supplemented by other parts, such as a coil, housing parts, inlets and outlets, etc.

The longitudinal members 16 have a square, in any case a rectangular cross section and are connected by welding, alternatively by screwing to the cross members 14, 15. It can be seen that the upper side members 16 lie with the upper cross members 14 in a horizontal plane, and that the lower side members 16 with the lower

 Cross beams 15 lie in a distance from the aforementioned level further horizontal plane parallel to the aforementioned plane. Both the feet 13 and the cross members 14, 15 and the longitudinal members 16 are formed from a steel sheet having a sufficient thickness to

to be largely rigid. It can be seen that a recessed area is provided in an area between legs 16 spaced by side members 16, in the work stations 30 and others for the

Production required parts can be arranged. It also recognizes that above the upper side rail 16 and the cross member 14 still

Structures can be set up. Finally, it can be seen that the spacing of the lower longitudinal member 16 and the lower cross member 15 from the lower region of the foot 13 also provides space for laying cables or for providing power supplies.

In Fig. 3 to 5, the production plant 10 is shown connected to the production rack 11 work stations 30 and disc spool magazine 50, wherein a workstation 30, which will be explained in more detail below, is mounted on one of the two lower side members 16. It can also be seen that on the lower side member 16, a worktop 16a is connected, which projects above the lower cross member 15. Further, it can be seen that on the workstation 30 opposite lower side rail 16 a further workstation 30 'is mounted, the present as

Blister belt conveyor and cutter is formed, which will be explained in more detail below.

It can be seen in Fig. 3 that on the upper side member 16 two

Handling devices 20 are connected, each end having a gripping system 20a. The gripping system 20a has a total of three grippers with which items can be used. In about the middle of the longitudinal members 16 in the region of the gap 17, a workpiece holder 60 is provided, in which the handling apparatuses 20 with the grippers of

Gripping system 20a can store items.

Above the upper side members, a frame 18 is constructed, in which a power supply, including a power supply and a compressed air supply and optionally a

 Hydraulic fluid supply and various cooling units are housed. Feeder lines can be lowered from a ceiling, for example, so that the corresponding lines the process of the

Production plant does not stand in the way. In Fig. 3 it can be seen that the workstation 30 does not rest on the ground on which the production rack 11 is supported, but this one

Distance has. A body 31 of the workstation 30 is with a

Kragbereich 32 equipped, which is arranged from above on the right in Fig. 3 lower side rail 16 and fixed there. A perpendicular to the Kragbereich 32 this limiting, in Fig. 3 to the left-facing end wall 33 is also on the lower side member 16, so that the angle of Kragbereich 32 and end wall 33 of the body 31 additionally stabilized by the likewise formed with an angle side rail 16 is. The cantilever 32 extends a work surface 34, on which a machine 40, which in the present case is a press, is attached. The press 40 is designed as a commercially available electric press, and has a press die 41 which is arranged coaxially to a workpiece holder 61, which forms a lower press tool.

It can be seen in Fig. 3 further that below the blister belt conveyor and - cutter 30 'trained workstation, which also has a

Kragbereich 32 'is connected to a lower side member 16, a movable over rollers 51a disc coil magazine 50 is arranged, which will be explained in more detail below.

Further details of the production facility 10 are shown in Fig. 4 as

perspective view and in Fig. 5 as a view from the side recognizable.

In particular, in FIG. 4 it can be seen that a system controller 18a as well as a power supply 18b and a cooling unit 18c are held in the frame 18.

Fig. 6 shows a top view of the workstation 30 without press 40 constructed thereon. It is understood that other machines may be placed on the workstation 30, such as a workstation 30

Laser welding machine, a concentricity testing machine, a

Leak tester, or other joining and forming machines. The work station 30 comprises the body designated 31, which has a projecting Kragbereich 32 which extends substantially horizontally. The Kragbereich is intended to mount the workstation 30 in a production plant 10 as shown above. For this purpose, the Kragbereich 32 has two downwardly extending centering mandrels 32a, further four holes 32b, with which the workstation 30 can be fixed to the side rail 16 or attached to the side rail 16 work table 16a. By hanging in the longitudinal member 16 is the

Workstation 30 not only fixed to the production rack 11 of the production plant 10, but also still spaced from the ground, so that no relative movements between the production rack 11 and workstation can arise due to vibrations. Moreover, the workstation 30 is exactly in relation to that connected to the upper side rails 16

Handling devices 20 positioned so that the tolerances are minimized here. As a result, the production line 1 or the

Production plant 10 can be operated without requiring optical

Recognition system must be provided, which determine whether the

Workstation 30 or built thereon machines 40 and then recorded workpiece holders 60, 61 are in the correct position. It goes without saying, however, that optical recognition systems can be used.

The Kragbereich 32 is arranged in extension of the horizontal working surface 34, are provided on the bores 34 a, 34 b, for the

Connection of a machine such as the press 40 are provided. It can further be seen that the end wall 33 lies in a plane perpendicular to the plane of the cantilever region 32 and the working surface 34, and extends over a narrow side of the body 31. In the end wall 31 a in Fig. 4 partially detectable opening 34a is provided, through which a power supply, illustrated via a cable 35 which is coupled to a cabinet 36, can be passed therethrough. In Fig. 6, the opening 34a is indicated only by broken lines. It can be seen in Fig. 6 that the cabinet 36 includes an electrical control 45 for the machine 40, which is connected to the cable 35. The

Electric control 45 also contains software-based control commands for the machine 40 and is connected via the cable 35 to a (not shown).

Connected system control, so not only the power supply via the cable 35 takes place, but also the connection to a

Plant control level.

The control cabinet 36 has a provided in the region of its longitudinal side door 36 a for access to the controller 45. Furthermore, the control cabinet 36 has an emergency stop switch 36b, which is arranged on a narrow side of the control cabinet 36, which is accessible to an operator. On the

Narrow side of the cabinet 36, a handle 36 c is further arranged, which serves to pull out of the cabinet 36, as will be explained in more detail below.

In a plane perpendicular to the end wall 33 and to the working surface 34, a side wall 37 is provided on the working surface 34 and on the end wall 33

connected, which is just like the working surface 34 with Kragbereich 32 and end wall 33 designed as a steel plate. On the side opposite the side wall 37 a web-like extension 38 is parallel to the

Side wall 37 connected to the underside of the work surface 34, which extends approximately only up to the height of the cabinet 36. The control cabinet 36 is received in the substantially cuboidal body 31, and pulled out of the body 31. For this purpose, a guide 38 is fixed on the one hand to the side wall 37, the other end of which is coupled to the rear side of the switching cabinet 36 facing away from the door 36a. The guide is formed as a telescopic roller guide with two guide rails, wherein the guide rails are arranged one above the other, so that the pair of guide rails connects the cabinet 36 to the body 31, and the cabinet 36 as well as the body 31 does not rest on the floor.

As a result, the cabinet 36 with little effort from the body 31 are pulled out, and once pulled out its door 36 are opened to gain access to the controller 45. As a result, the workstation 30 can be made quite narrow, whereby several

Workstations 30 side by side on the production plant 10th

can be connected, and at the same time the station control is easily accessible, without the cabinet must be kept outside of the work stations for this purpose.

It can be seen that the Kragbereich 32 as lying in the same plane

Extension of the working surface 34 is formed, which can be realized in a particularly simple manner, but it is also possible to offset the Kragbereich opposite the working surface 34 vertically, for example by providing a step. In the same way, for example, the blister belt conveyor and cutter 30 'are equipped with a cantilevered area 32', resulting in a high degree of flexibility with respect to the connection possibilities of workstations 30, 30 ', which are also connected differently in their order to the production rack 11 of the production facility 10 can. The replacement of a workstation is simple, since it is sufficient to solve through the openings 32b guided through screws and then lift the entire workstation with a pallet truck from the production rack 11. In this way, a defective workstation 30 can be replaced with machine 40 quickly and easily. The entire production line 1 can thus easily be converted to another product by moving the workstations 30, even if it is advantageously provided that the workstations 30 are arranged on the production line 1 in such a way that different assemblies can be manufactured without the entire workstation 30 or arranged on the workstation 30 machine 40 must be replaced for this purpose. In the area of the workstation 30, advantageously on the working surface 34, a workpiece holder 61 can be arranged, which can be designed as explained below with reference to the workpiece holder 60. In Fig. 7 to 11, the disc spool magazine 50 is shown in more detail. The disc spool magazine 50 has a holder 51 which, in the view shown in FIG. 7, can arrange a plurality of adjacently arranged disc spools 52 side by side. The disk spools 52 are used to wind up items delivered in a blister belt, each disk spool 52 having two side disks 52a which define a tubular core 52b at the front. On the core 52b, a blister strip is spirally wound, so that in each

Blister belt recording each a single item is provided. The blister strip is withdrawn from the blister belt conveyor and cutter 30 'while rotating the pancake coil 52, withdrawing a blister film picking film in the area of the blister belt conveyor and cutter 30' from the blister belt pickup, thereby allowing the picking system 20a access to the item. The blister belt conveyor and cutter 30 'ensures that the item always in the field of

 Blister belt receptacle is arranged, where a gripper of the gripping system 20a can receive it.

The individual parts are elongate, at least predominantly or substantially rotationally symmetrical parts which are transverse to the

 Are fed rotation axis, so that the gripper finds each item always in a predetermined orientation and can accommodate this.

Since the items have a fairly high weight, it is not sufficient to insert a cutting disc between adjacent disc coils in the holder 51, which prevents adjacent disc coils 52 obstruct each other, for example, if they are bent or have another defect. Furthermore, it is expedient, a disc coil 52 with due to the weight of the items very high mass, the

Substantially about the blister belt is rotated to arrange as low friction and reliable in the axis of the blister belt conveyor and cutter 30 to damage or elongation of the

Avoid blister straps. For this purpose, the holder has two disc coils 52 radially supporting support cylinder 53 on which the disc coil 52 is supported. The two support cylinders 53 are arranged parallel to each other in a horizontal plane and spaced from each other in the horizontal plane that they rest radially on the circular periphery having side discs 52 of the disc coil 52, wherein approximately centrally between the axes 53 a of the support cylinder 53 of the tubular core 52b of the disk coil 52 is located. As a result, the disk coil 52 rests securely on the support cylinders 53, and upon rotation of the disk spool 52, the friction that arises is merely that of the support cylinder 53.

If each disc coil 52 is assigned an individual support cylinder 53, the friction can be further reduced by the support cylinder 53 itself being rotatably mounted, so that the support cylinder 53 also rotates counter to the disc coil 52. For this purpose, it can be advantageously provided that a plurality of support cylinders 53 each supporting a disk coil 52 are arranged independently rotatably on a shaft or are coupled to a shaft via a roller bearing, so that each has a disk coil 52

supporting support cylinder 53 individually rotates. In the view of FIG. 8, which shows the disc spool magazine 20 from the front, without a frontal lining of the holder 51, it can be seen that the disc coils 52 extend vertically quite far up and also vertically

Overhang bracket 51. It will be understood that the rotational speed of the disk coils 52 will vary, even after whether the blister strip is remote from or adjacent to the tubular core 52b.

Fig. 9 shows the holder 51 along the line IX - IX of Fig. 7 in a cross section. It can be seen the tubular core 52b indicated by dashed lines of the disk coil 52 and the circular outer periphery of the

Side plate 52a of the disc coil 52. Furthermore, you can see how the

Support cylinder 53, the disk coil 52 radially supported. The rollers 51a (see Fig. 3) of the holder 51 of the disk reel magazine 50 are not shown in Fig. 9, nor is one for a pushchair-type transport trained, bow-shaped folding handle 54, which is clearly visible in Fig. 3.

It can be seen in FIGS. 7 and 8 that the two support cylinders 53 can radially support a plurality of disk coils 52, namely one in the region of each of their radial elevations 530. The extent of the radial elevation 530 in the direction of the axis 53a of the support cylinder 53 is dimensioned such that in that the elevation 530 can be inserted between the two side windows 52a of a respective disk coil 52. This can be seen in Fig. 7, from which further shows that the survey 530 also a bit shorter than the

Distance between the two side windows 52a of a disk coil 52 may be performed in order to be used reliably in the intermediate area. The support cylinders 53 have a plurality of radial elevations 530, so that a total of 51 disc coils 52 can be arranged in the holder 51. In the illustration according to FIGS. 7 and 8, the radial elevations 530 each have the same axial extension. However, it is possible that the radial elevations 530 of the same support cylinder 53 also

different axial extensions, so widths, may have to accommodate different width disc coils 52 in a holder 51 can.

10 and 11 show enlarged in side view and longitudinal section

Pad cylinder segment 53 ', from which the support cylinder 53 are assembled. Here, the support cylinder segments 53 'each have (not shown) coupling portions in the direction of the axis 53a

plugged together, as can be clearly seen in particular in Fig. 11. The

Coupling sections may in this case be provided as hollow cylinders whose inner diameter approximately corresponds to that of an inner diameter 531 of the support cylinder segment 53 '. The coupling sections are covered by end-face annular extensions 532 of the support cylinder segment 53 'and thus form a positive connection. It can be seen in FIGS. 10 and 11 that a radial chamfer 534, which falls down outwards onto the level of the front-side annular extensions 532, is provided on the radial elevation 530, which has a substantially continuous transition between the outer sides the smaller outer diameter annular projections 532 and the larger outer diameter radial projections 530. The chamfers 534 center the support cylinder segment 53 'at the area between the side disks 52a of the disk coil 52, so that the disk coil 52 does not migrate in the direction of the axis 52a. Thus, the support cylinder 53 also forms an axial support for the disk coil 52 by its profiling.

It can be seen that the support cylinder 53, from the

Pad cylinder segments 53 'are assembled, are formed as a hollow body. In this way, a shaft or a shaft can be guided through its central bore 531, with which the support cylinder 53 are fixed to the holder 51. The support cylinders 53 are made of steel, so that they hardly occur even with prolonged use and the relative movement of the heavy disc coils 52 damage. The

Platen cylinder 53 are disposed in a bottom portion of the holder 51 and have a distance which is smaller than the diameter of the side window 52a, but preferably at least half the diameter of the side window 52a and preferably still a little larger, the disk coil 52 a stable Stop. It can be seen in Fig. 9 that by providing the support cylinder 53, the disc coil 52 does not come into contact with a bottom of the holder 51 or with another wall of the holder 51, whereby a free rolling is enabled. Fig. 12 illustrates a detail of the production plant 10 which results in that various assemblies can be manufactured on a production line. Here, the workpiece holder 60 of FIG. 1 is shown schematically enlarged. The workpiece holder 60 has a support 63, which is slidably connected via a provided on the support 63 guide 63a in the direction of the double arrow 64 on the longitudinal member 16. On the support 63 four different workpiece receiving vessels 601, 602, 603 and 604 are arranged side by side in the direction of the double arrow 64, wherein the workpiece receiving vessels 601-604 each to a concrete of is adapted to several producible on the production plant 10 assemblies. In particular, the workpiece receptacles 601-604 have the task of housing the housing to be manufactured, which is the largest of the individual parts of the assembly, in which then the other parts are arranged to receive. For a better illustration, the

 Workpiece receiving cavity of the workpiece receiving vessel 601 shown cut. This is, as will be explained in more detail below, a housing defining sleeve A. The support 63 is designed to be displaceable overall, whereby the series of workpiece receiving vessels 601-604 can also be moved in the direction of the double arrow 64 along the longitudinal member 16. The displacement of the support 63 is required if the production plant is to be converted from one specific assembly to the other. In most cases, it will be necessary to supply different items for this, so that the disc spool magazine 50 therefor against another

Disc Coil Magazine 50 is exchanged with other items. In order not to have to re-set up the entire production line 1 or production plant 10 with tool holders 60 adapted to the assembly to be produced, it is sufficient to move that workpiece holder to a working position that is assigned to the assembly to be produced. This advantageously achieves that a new

Overall equipment of the production plant is not required, and

In particular, a once granted approval for series production, which would extend to the displacement of the support 63, even in the interim production of other modules inventory. This is the

Production plant 10 can be used with maximum flexibility, whereby the conversion from one assembly to the other assembly does not need to be done manually.

It is possible that the handling apparatus 20 with its gripping system 20a, the displacement of the support 63 with the connected thereto

Workpiece receiving vessels 601-604 in the direction of the double arrow 64th shifts, wherein the projections 63a of the support 63 are held in such a clamping manner in the region of the longitudinal member 16 that vibrations do not lead to a displacement in the direction of the double arrow 64. In the present case, however, the support 63 has its own drive, which is not shown, which displaces the respectively to be loaded workpiece receiving vessels 601-604 to an optimal position for the handling apparatuses 20. As a result, the particular adapted to the module specific is advantageous

Workpiece receptacle 601-604 is arranged with its axis in the correct position. Accordingly, the workpiece receiving receptacles of a workpiece holder 61 in the region of a machine 40 are changed in their position when it comes to the production of another module on the

Production plant 10 is coming. The plant control system causes the drive to automatically shift the support 63 when it is retrofitted to another product or another subassembly, so that no

separate handles of an operator are required. A sensor associated with the support may be provided to check that the correct workpiece receptacle 601-604 is in the working position.

As an alternative to an arrangement of the workpiece receiving containers 601-604 on a support, these can also be arranged in each case on a separate support, wherein by moving the then together

even the entire row is moved. Above all, the advantage of a single arrangement on a support 63 is that the workpiece receiving containers can be removed without interrupting the ongoing operation when the specific assembly is not being built.

The workpiece holder 60 is arranged at a transfer station between the two handling apparatuses 20 of a production facility 10, cf. 1 so that individual parts received by the gripper system 20a of the handling apparatus 20 can be deposited in the workpiece holder 60 in the associated workpiece holder 601-604. Does that know

Gripping system 20a of the handling apparatus 20 on three grippers, for example, only three items from the blister straps 80 recorded and then these are stacked in the correct order in the workpiece holder 60 stacked together, so that the number of

Movements of the handling apparatus 20 itself is reduced, and that designed in the manner of a revolver or star gripping system 20a connects the items together in the tool holder 60 substantially in rapid succession. Here are between two and eight items in the

Workpiece holder 60 connected to each other, suitably between three and six items. It can be seen that the production plant 10, if it is equipped, for example, with a plurality of disc spool magazines 50, can also produce two different assemblies simultaneously. Appropriately, then the specific workpiece holders are each at the

Production plant 10 is provided, but it is also possible that this support 63 is moved during operation in the direction of the double arrow 64 back and forth.

FIG. 12 further shows how one executed on the production plant 10

Method for producing at least approximately rotationally symmetrical components of several individual components works:

Illustrated schematically are four blister straps 80, which are covered with a cover film, not shown, and which have successively arranged cavities 81, the foremost one of which is exposed in FIG. 12. In the cavity 81 of the blister straps 80, a rotationally symmetrical component A, B, C, D is respectively arranged, which have an axis which is substantially transverse to the

The conveying direction 83 of the blister strip 80 runs.

The gripping system 20a with a total of three grippers now engages in a first step, the three items A, B, C, each with a gripper of the gripping system 20a. The item A is a case forming a sleeve, the item B to a cylindrical anchor, the item C to a perforated pole core and the item D to an anchor rod, which also is referred to as a piston rod. The individual parts form, assembled and then optionally pressed, a core assembly or magnet assembly, which in a component such as a magnetic pump or a solenoid valve, which on the

Production plant is assembled and connected in further steps, is used.

The gripping system 20a places first the largest item A in the at

Working position moved workpiece holder 601 of

Workpiece holder 60 a (shown in Fig. 12 as a sectional view), then the component B, the component D and the component C are inserted into the component A, which is particularly favored by the fact that the components A, B, C , D substantially elongated,

are rotationally symmetrical components, with their axis transverse to

Be provided conveying direction of the blister straps 80 so that the gripper of the gripping system 20a can pick them up quickly and then insert in the direction of its axis in the workpiece holder.

In fact, first, the sleeve A is inserted into the workpiece holder 601 by one of the grippers, the tolerances being such that the sleeve A is clamped under its own weight without jamming

 Workpiece receptacle 601 can slide (see Fig. 12). Then, by another gripper, preferably the same handling apparatus 20, the anchor B is inserted into the sleeve A (see Fig. 12A). Again, the anchor B slides without external force in the sleeve A. Thereafter, from another gripper possibly belonging to another handling apparatus 20, the anchor rod D is inserted into a central bore of the sleeve A (see Fig. 12B). Again, the application of a force is not required because the fit of the bore of the armature A and anchor rod D has enough clearance. Finally, the pole core C is inserted into the sleeve A by another gripper, with an annular step formed on the circumference of the pole core C.

avoids that the pole core C rests on the armature B. It is understood that in the workpiece holder 601 other items can be used, such as springs, such as coil springs or Disc springs, housing parts, dosing cylinders, valves, etc.

It can be seen in FIG. 12 that an optical monitoring device 70, which together form a light barrier or which is designed as a CCD line or matrix camera, is arranged on upper lateral stops 63a of the support 63. The optical monitoring device 70 checks whether the individual parts were each successfully installed. In particular, the optical monitoring device 70 can stop the continuation of the assembly if a part is not designed according to the default, for example inserted wrongly or not in alignment, so far the optical monitoring device 70 also monitors the function of the gripping systems 20a. The optical monitors 70 are equipped with an antenna 71 for wireless communication, but may also be connected to the controller via cables.

If an intermediate product is formed from the individual parts A, B, C, D, the gripping system 20a of another handling apparatus 20 can grasp it and feed it into the workpiece holder 61 of a press 40 which is arranged on a workstation 30, which is described below in FIG Fig. 13 will be explained in more detail. The assembled magnetic assembly of the items A, B, C, D is from a gripper 20 a of the

Workpiece receiving vessel 601 taken out together and fed to a workpiece holder 61 of a press 30. Fig. 13 shows a arranged on a work table 30 press 40, wherein the work table 30 is disposed opposite to the production plant 10 with respect to the blister 80 promotional disk spool magazines 50 opposite. Also in the press 30, the workpiece holder 61 is corresponding to the to

producing component, in this case the composite magnet assembly adapted.

The workpiece receiving vessels 601-604 is further associated with at least one separate sensor, which at least detects whether in the Workpiece receiving vessel an item as a housing or a sleeve A is arranged. This sensor may be pneumatic, electronic or capacitive. If no sleeve A is detected in the vessel 601 in the correct position by the sensor, the control prevents the depositing of one of the parts B, C or D. It is also detected whether the armature B is in the sleeve before the anchor rod D is inserted , And whether the anchor rod is inserted before the pole core C is used. This monitoring is performed in addition or in addition by the optical monitoring devices 70. Especially with rotationally symmetrical parts there is an increased risk that an item in the blister 80 was accidentally placed the wrong way round. Therefore, it is expediently provided that the items are coordinated so that they show a different, so optically detectable silhouette when installed incorrectly when installed correctly. This is achieved for the sleeve A in that the bottom is closed at one end and open at the other end. This is achieved for the armature B in that either the bore for receiving the anchor rod is only provided on one side, or provided on only one end face cone, this is achieved for the anchor rod C in that eccentrically a radial collar is provided , This is achieved for the pole core C by a radial step or a counter-cone to the armature B.

Is the preassembled intermediate in the workpiece holder 60th

completely, the gripping system 20a of the adjacent takes

Handling apparatus 20 on this and leads it to a workpiece holder 61 of the machine 40 designed as a press, wherein the workpiece holder 61 then forms the lower tool of the two-part pressing tool, while the ram 41 forms the upper tool of the pressing tool. In the best case, the upper tool 41 for all the individual

Workpiece receiving containers of the workpiece holder 61 the same, so that no conversion must be done here; Alternatively, the upper tools may be arranged in the manner of a carousel, which is used in each case adapted to the assembly to be built. It can be seen in FIG. 13 that the four lower tools 61 of the workpiece holder are mounted on a support 65 which can be moved transversely to the pressing direction, where they can be displaced together by a separate drive (not shown) or under the action of a handling apparatus 20. The displacement movement is by a driven belt 66, which is in engagement with the support 65 and between

End pieces 67 is clamped, transmitted to the support 65. Also, the support 63 may be equipped with such a drive. It can further be seen in FIG. 13 that the workpiece holder 61 on the right is aligned with the upper tool 41 connected to the press 40 and is ready for pressing the magnet assembly A, B, C, D, which is not yet inserted into the workpiece holder 61. It can also be seen that the belonging to the immediately adjacent workpiece holder 61

Upper tool 41 during the production of other parts in the

 Workpiece holder 61 rests and thus a separate tool magazine is not required. The upper half of the upper tool 41 is designed as a tapered tool guide, which can be accommodated in the downwardly displaceable press part of the press 30.

In the workpiece holder 61, the pressing step is then carried out to the effect that, with the upper tool 41 designed as a caulking tool, the pole core C is at a distance from the armature B with that in FIG

Workpiece holder 61 recorded caulked A is.

After pressing, the same gripper 20a takes the pressed or

caulked component and exchanged it for another intermediately produced intermediate product so that it can be pressed. The compressed product is transferred from the gripping system 20a to a next one

Workstation 30 or a next workpiece holder 60 or a next handling apparatus 20 passed, or if it is already a finished product, placed on a corresponding tray. The manufacturing method described above is particularly suitable for producing assembly parts that are selected from the group consisting of electromagnets, electromagnetically actuated actuators, electromagnetically actuated valves, electromagnetically driven

Metering pumps, electric motor control systems, electric motors and

Assemblies and magnet assemblies of the aforementioned components assembly. These components are characterized by their essentially

rotationally symmetrical shape, which also for the invisible

Components applies. Moreover, the processing steps, ie in

Essentially assembling, pressing, laser welding, and the

Test steps, for example optical measurement, tightness measurement,

Function measurement, executable on the same machines, so that a

Production plant can be used for various of the assembly components. Different members of a product family can be produced on the same production plant 10 with very little setup effort.

It can be seen that the method advantageously without a direction of the

Side member 16 extending conveyor belt is executable, and that

In particular, the handling devices that receive the items and equip the machines are also used for the removal of the finished components. In this case, very favorable cycle times are achieved, which leads to a shortened production time of the products. Moreover, the set-up time is reduced to a fraction of the otherwise incurred time. Furthermore, by the

Production plant 10 or production line 1 only a small one

Land use given so that the production line 1 and the

Production plant 10 very compact fails. By avoiding driven belts and the like, the production plant 10 is extremely clean and can also be used under clean-room conditions. The production plant achieves a fully automatic

Assembly of products with low conversion costs and cheaper

Expandability. The production facility 10 can be used for very high outputs, in particular for the fully continuous production of the named products.
