Abstract

The invention relates to a melf varnishing machine (6) in which the melfs (1), fitted in holders in a transport device (11), are moved with the aid of the latter by means of a conveyor drive on a transport device (11) moving on a closed conveyor path in a transport direction past at least one varnishing station (33, 34) and then through at least one drying region (35). The melfs (1) roll in the transport direction on at least a surface of a conveyor section of the conveyor path adjacent to the varnishing station (33, 34) on their capped ends (3) by rotating around a longitudinal axis lying transversely to the transport direction.

Description

 Melf painting machine

The invention relates to a Melf painting machine according to the preamble of claim 1.

"Melf" is understood to mean an electrical component, for example an electrical resistor, which has an essentially circular-cylindrical component body which is provided at both ends with a cap which forms the electrical connection. These components have extremely small dimensions. When implemented as a micro-melf, the axial length is, for example, in the order of 2 mm and the diameter on the caps is in the order of 1.1 mm.

In the production of such melfs it is, among other things, also required, after capping, to provide the part of the peripheral surface of the component body which is exposed between the caps with a protective and electrically insulating coating made of lacquer or another suitable material. Furthermore, it is usually also necessary to apply coding in the form of colored rings to the part of the component body which is exposed between the caps. The application of the coating and / or the application of the color coding rings is referred to as "painting" in the sense of the invention. With this painting, it is necessary to apply evenly without any imperfections, such as "paint noses" etc., and to apply the paint only to the area free of the caps, which has an axial length, for example, of the order of 1.5 mm has, remains limited, so no paint gets on the caps.

A machine has already been proposed for painting Melfs, but not in their training as micro-Melfs, in which the Melfs are used in a feed station in receptacles of a transport element formed by an endless conveyor belt, then with this conveyor belt formed by a steel belt at painting stations are moved past and then conveyed through drying zones in which the paint applied to the painting stations is dried under the influence of heat. By appropriately designing the receptacles in the conveyor belt, it is ensured that the Melfs roll on a surface of the conveyor line about their longitudinal axis in order to maintain a uniform coating application after painting.

This Melf coating machine has considerable disadvantages which, among other things, consist in the fact that the part of the transport route running through the drying zone must be relatively long, particularly in the case of high output, ie with a fast-moving conveyor belt, in order to achieve the required drying time. This means that the conveyor belt must have a great length. However, the production of the conveyor belt with the required length and the necessary recesses is very complex. The recording can only be made in the conveyor belt, which is designed as a steel belt, by punching out. This results in very rough, high-friction contact surfaces for the Melfs or their caps in the area of each receptacle, so that a perfect rolling off of the Melfs after painting to maintain a uniform layer of paint and to avoid paint noses, etc. is not guaranteed. Furthermore, it is not possible, among other things, to guide the conveyor belt at the painting stations with an extremely high level of accuracy required when processing micro-melts. In order to avoid the problems with regard to driving and guiding a very long conveyor belt, a separate conveyor belt is provided for the drying zones in the known machine, in particular at higher outputs. However, this means that the Melfs must be removed from one transport and used in the other.

Figure imgf000004_0001

Finally, cleaning and / or repairing the transport system of this Melf coating machine is not only complex, but also requires the entire machine to be shut down. The invention is based on the object of demonstrating a Melf coating machine which avoids the abovementioned disadvantages and, despite a lower design outlay, enables coating of Melfs, in particular also of MicroMelfs, with high precision.

To solve this problem, a Melf painting machine is designed in accordance with the characterizing part of protection claim 1.

The particular advantage of the Melf varnishing machine according to the invention is that the transport system is formed by cassettes moving on a transport or conveyor line. As a result, the transport system is subdivided into small units, each unit or each cassette being able to be guided very precisely, at least where necessary, by appropriately guiding the conveyor line.

Since the cassettes are rigid, a further advantage is that any suitable material can be used for these cassettes. In addition, manufacturing techniques can be used for the production of the cassettes and in particular also for the production of the receptacles, which ensure optimal surface design of the cassettes, in particular also in the area of the receptacles.

It is also advantageous with the Melf coating machine according to the invention that, for cleaning or repair purposes, individual cassettes can be removed from the system without the need to shut down the coating machine. The cassettes removed for cleaning or repair purposes can be replaced by replacement cassettes. Furthermore, in the Melf coating machine according to the invention it is also possible, for example for test purposes, to remove a cassette equipped with a large number of Melfs practically at any point in the transport system. Further developments of the invention are the subject of the subclaims.

The invention is explained in more detail below with reference to the figures using an exemplary embodiment. Show it:

In the figures 1 are electrical components, for example in the form of resistors, which are also referred to as Melf and have an essentially circular-cylindrical component body 2, which is provided at both ends with a cap 3 forming an electrical connection. The Melfs 1 are micro-Melfs that are extremely small Have dimensions. The axial length is, for example, on the order of 2 mm. The diameter in the area of the caps 3 is, for example, 1.1 mm.

After the caps 3 have been applied to the component body 2, the latter must be provided with a coating 4 formed by one or more layers on its peripheral surface lying between the two caps 3. In further work steps, a plurality of color rings 5 forming a color coding are then to be applied to this paint 4. In order to be able to carry out this work cleanly with the extremely small and light Melfs 1, and in fact without a coating application to the caps 3, the Melf coating machine 6 described in more detail below in connection with FIGS. 2 to 7 is used.

This Melf coating machine 6 essentially consists of a self-contained transport section which, in the embodiment shown, is composed of a total of four sections which are essentially arranged in a common horizontal plane and adjoin one another, namely the longitudinal conveyor section 7, from the transverse conveyor section 8 adjoining it vertically in the transport direction A, from the longitudinal conveyor section 9 adjoining it in the transport direction and from the transverse conveyor section 10 adjoining this in the conveying direction. The conveyor section or the aforementioned sections of this conveyor section are provided with a A large number of elongated cassettes 11 are occupied, each of which can accommodate a total of forty Melfs 1 in the embodiment shown and which close together in the longitudinal direction L and on the transverse conveyor sections 8 on the longitudinal conveyor sections 7 and 9 with their end faces 12 and 10 are moved with their long sides 13 close to one another in the transverse direction, that is to say transversely to their longitudinal extension L. The cassettes 11 together with the conveyor line or their conveyor sections 7 to 10 form a transport system or a transporter with which the Melfs 1 are moved past the various negotiating stations. Each cassette 11 essentially consists of two parallel strips 14 which extend in the longitudinal direction L and each have the same cross-sectional profile, which is composed in one piece from a rectangular profile section 15 and a strip-like profile section 16. The strip-like profile section 16 stands laterally in the middle of one of the longer cross-sectional sides of the profile section 15 and also has a rectangular cross-section, so that each bar 14 is symmetrical with respect to a central plane designated Ml in FIG. 4 is. The two strips 14 of each cassette 11 are connected to one another at the two end faces 12 of the cassette by connecting webs 17, in such a way that the strip-like profile sections 16 of the two strips 14 face one another and lie in the common plane M1, with a mutual spacing , which is smaller than the axial length of the Melfs 1, ie approximately corresponds to the exposed or not covered by the caps 3 axial length of the component body 2. The connecting webs 17 which connect the strips 14 to one another are made from a flat material with a thickness which is smaller than the diameter which the Melfs 1 have in the region of the caps 3. Furthermore, in the embodiment shown, the thickness of the profile sections 16 of the strips 14 perpendicular to the plane M1 is the same or slightly smaller than the diameter of the caps 3.

Between the two strips 14 and the profile sections 16, a plurality of receptacles for the melfs 1 are formed, which are then arranged in these receptacles with their longitudinal axis perpendicular to the longitudinal extension L of the cassette 11 and parallel to the plane M1. Each receptacle is formed by two recesses 18, which are opposite each other in pairs in an axial direction perpendicular to the central axis M2 and are formed in the profile sections 16. Each recess 18 is open both to the central plane M2 and to the top and bottom of the profile section 16. As FIG. 6 shows, each recess 18 has cross-sectional planes parallel to the central axis M2, a cross-sectional width that decreases towards the lower side 16 ″ of the profile section 16 in such a way that the opening width of each recess 18 on the upper side 16 ′ is larger than the diameter of the caps 3, on the lower side 16 However, is smaller than this diameter of the caps 3. The length of each recess 18 in the axial direction perpendicular to the central axis M2 is at most equal to the axial length of the caps 3, so that the Melfs inserted into the cassette 11 from above are only in the area their cap 3 are in the recesses 18. Due to the above-described cross-section of the recesses 18, which of course each have a constant cross-sectional shape in the axial direction perpendicular to the central axis M2, it is possible to remove a cassette 11 equipped with Melfs 1 from the conveyor line without the Melfs 1 from the cassette 11 fall out. Rather, these are then supported with their caps 3 on the boundary wall 19 of the respective recess 18.

In the area of the longitudinal conveyor sections 7 and 9, the conveyor track is formed by a profile rail which, at least in its upper area, has a rectangular or square cross section with an upper guide or sliding surface 21. The cassettes 11 with the respective underside 16 ″ rest on this sliding surface 21, which has a groove 21 ′ extending in the middle in the transport direction A. For lateral guidance, the profile rail 20 is overlapped on the two long sides of each cassette 11 or by the parts of the profile sections 15 projecting beyond the undersides 16 ″. The profile sections 15 and 16 thus form sliding and guiding surfaces with which an exact guidance of the cassettes 11 along the longitudinal conveyor sections 7 and 9 or the profile rails 20 there is possible with small tolerances.

When the cassettes 11 are moved on the longitudinal conveyor section 7 and 9, the caps 1 rest with their caps 3 on the sliding surface 21 and thereby roll on a sliding surface, so that a continuous rotary movement of the caps about their axis is achieved, as indicated by arrow B in Fig. 6. This rolling movement is necessary in order to avoid the formation of drops or paint noses in the various painting processes, and as long as the respective paint has not yet been sufficiently predried.

If particularly precise guidance of the cassettes 1 and / or arrangement of the melfs in the cassettes 11 is required at certain workstations, the profile rail 20 is inclined at an acute angle a transversely to the conveying direction A at least in these regions of the longitudinal conveying sections 7 and 9 . As a result, the Melfs 1 move in the respective cassette 11 (also supported by their rolling movement on the surface 21) in such a way that all Melfs 1, each with a cap 3, lie against the end of the respectively lower recess 18, so that all Melfs in with respect to a common plane, namely with respect to the plane of the closed ends of the deeper recesses 18 are exactly positioned. Due to the inclination of the profile rail 20, it is also achieved that all the cassettes 11 with the corresponding profile section bear against the higher longitudinal side of the profile rail 20, thus also to the extent that an exact positioning of all the cassettes 11 in relation to a certain plane or area is achieved.

For exact positioning of the cassettes 11, resilient rollers 22 can also be provided on corresponding areas of the conveying path, pressing the respective cassette 11 with a profile section 15 against a predetermined longitudinal side of the profile rail 20.

If there is a danger in certain areas of one or both longitudinal conveyor sections 7 or 9, for example at the work or painting stations there, that the Melfs 1 are affected by forces acting from below, for example by a painting wheel shown in FIG. 7, acting from below 23 so far that the Melfs 1 with the caps 3 are lifted out of the recesses 18, it may be expedient or necessary to provide an upper support in such areas to be provided, but only for the caps 3, while the peripheral surface of the component body 2 which is exposed between these caps 3 does not touch the support. This support is preferably an element which forms support surfaces for the caps 3 which move in the transport direction A or counter to the transport direction. This support is, for example, a wheel 24 which is rotatably mounted about an axis 25 which is perpendicular to the transport direction A and parallel to the sliding surface 21. The wheel 24 has an axial width that is equal to or slightly smaller than the distance that the parts of the profile sections 15 of the two strips 14 of a magazine 11 projecting above the top side 16 'of the profile sections 16 are at a distance from one another. In the central region, the wheel 24 is provided with a circumferential groove 26, in such a way that the wheel 24 only forms the contact surface with the circumferential regions 27 formed on both sides by this circumferential groove 26, and only for the caps 3. that the wheel with the peripheral regions 27 runs against the Melfs 1 properly arranged in the receptacles or recesses 18, but on the other hand to ensure that the peripheral regions 27 of the wheel 24 act reliably as contact surfaces for the caps 3 of the Melfs 1 is the thickness of the Profile sections 16 (distance from top 16 'to bottom 16'') equal or slightly larger than the diameter of the caps 3.

Since the cassettes 11 connect closely to one another on the longitudinal conveyor sections 7 and 9 during normal operation, the upper sides 16 * of the profile sections 16 of the adjoining cassettes 11 form continuous surfaces on which the wheel 24 in question can roll. Since the connecting webs 17 on the two end faces 12 do not protrude above the upper side 16 'or the lower side 16''of the profile sections 16, vibration-free rolling without lateral deflection of the wheel 24 is possible. At the transverse conveyor sections 8 and 10, the cassettes 11 are moved further with their longitudinal axis L perpendicular to the transport direction A and are guided in guides 28 on both end faces 12 for this purpose.

The further movement of the cassettes 11 on the longitudinal conveyor sections 7 and 9 and the transverse conveyor sections 8 and 10 is carried out by thrust elements 29 and 30, which in the embodiment shown are each formed by hydraulic cylinders, the thrust elements 29, each on the The beginning of the longitudinal conveyor sections 7 and 9 are provided, for example have a stroke which corresponds to a length of the cassettes, while the stroke of the thrust elements 30 provided at the beginning of the transverse conveyor sections 8 and 9 is the same or slightly larger than the width of the cassettes 11.

In the painting machine shown in FIG. 2, a feed station 31 is provided at the beginning of the longitudinal conveyor section 7, at which the melfs 1 in a bunker or storage container 32 are placed in the required orientation in a cassette 11 provided at the feed station 31. This insertion is preferably carried out in such a way that a group having a plurality of Melfs 1 is simultaneously inserted into the cassette 11, for example a group of twenty Melfs 1, so that the required number of Melfs 1 is introduced into the cassette 11 in two work cycles.

In the transport direction A, the painting station 31 is followed by two painting stations 33 and 34, in each of which a layer of paint is applied to the component body 2 between the caps 3 with a wide painting wheel 23. In the area of this painting wheel 23, the profile rail 20 has an opening 20 '. Since the melts 1 of the above-described manner continuously roll with their caps 3 on the sliding surface 21 when the cassettes 11 are moved further, a uniform distribution of the paint film applied to the coating stations 32 and 33 is ensured, in particular also in a pre-drying zone 35 adjoining the coating station 34, in which the applied coating layer is pre-dried at least to the extent that the coating no longer runs or drips by the action of heat or infrared.

The predrying zone 35 extends to the end of the longitudinal conveyor section 7. In the transverse conveyor section 8, the cassettes 11 are moved by a drying oven 36 which has infrared radiators 37 above and below the path of movement of the cassettes 11.

The cassettes 11 with the dried melts 1 then arrive at the longitudinal conveyor section 9, at which a plurality of coding stations 38, i.e. In the illustrated embodiment, a total of five coding stations 38 are provided in succession in the transport direction A. A color ring is applied in each coding station 38, specifically by means of a painting wheel 23 ', which is narrower than the painting wheel 23 and is tapered on its circumference like a knife edge. All coding stations 38 are located on the longitudinal conveyor section 9. After the cassettes 11 have been transferred to the transverse conveyor section 10, the cassettes 11 are moved by a drying oven 39 corresponding to the drying oven 36. At the end of the cross conveyor section 10, an unloading station 40 is formed, at which the Melfs 1 of the respective cassette 11 are removed, which then finally arrives at the loading station 31 as they move further in the transport direction A.

The invention has been described above using an exemplary embodiment. It goes without saying that numerous changes and modifications are possible without thereby departing from the inventive idea on which the invention is based. In particular, it is also possible to design the transport route, which is composed of longitudinal and transverse conveyor sections, and the type and distribution of the work stations on this transport route, in accordance with the respective product, differently than described. Furthermore, it is also possible, instead of the cross conveyor sections 8 and 10 conveyor sections to be provided, on which the cassettes are moved in the vertical direction or in the vertical and horizontal directions in order to achieve the longest possible drying distances in a small space or space requirement and thus to achieve sufficient drying times even with high performance of the coating machine.

Basically, the cassettes 11 and / or the guide profile for the cassettes on the longitudinal conveyor sections can also be designed differently than described, but while maintaining the basic principle that the melfs 1 arranged in the cassettes 11 move with their caps 3 when moving along the longitudinal conveyor sections pass on. However, the cassettes 11 described above have the advantage that they are symmetrical both with respect to the central plane M2 and also essentially with respect to the central plane M1. Neither during predrying nor during drying can the cassettes 11 warp due to the action of heat. The described profile of the strips 14 not only results in the possibility of simple and reliable guidance on the profile rail 20, but also results in a stable construction in mechanical and thermal terms for the cassettes 11.

Furthermore, it is not only possible to design the transport or conveying path of the respective machines in terms of their length in accordance with the respective requirements, but it is also possible to design in particular the transverse conveying sections 8 and 10 in several levels or floors so that the effective length of these transverse conveyor sections is variable, depending on the product and / or depending on the output.

The use of the cassettes 11 not only has the advantage that exact guidance is ensured with relatively simple structural means, but that the cassettes 11 and also the cassette guides on the conveyor sections can be easily cleaned. Furthermore, in the case of repairs or cleaning, it is possible to remove from the machine only those cassettes 11 which actually do cleaning or require repair, while the remaining cassettes 11 remain in the machine and the operation of the machine is not interrupted.
