Definitions

• the invention relates to a device for loading layering screws with wax according to the generic term of claim 1.
• a coating agent e.g. paints, synthetic resins, but also chemicals or Wax.
• capacitors are coated with a electrically conductive metal track or smaller components with Paint or screws with wax, just to name a few to call.
• Wax-coated screws for example, reseal The screw holes opposite the screwing in, e.g. Moist better than screws without such a coating.
• the object of the present invention is therefore to provide a one direction for the automatic coating of screws with Provide wax with the also non-magnetic screw exercise comfortably regardless of their length can be layered.
• the cradle connections can be formed, for example, by the fact that the outer Lugs are angled on one side of the chain.
• the bent part is according to the invention with at least ei nem, preferably two to three, to the outer longitudinal edge Reaching slots provided.
• the slots on the side adjacent parts of the receiving device support the screw heads, while the screw shank through the slot through pointing down.
• the continuous feeding of the screws to the Auf Pick-up devices take place in a known manner via e.g.
• a Feed chute upstream of which, for example, a sorting unit in which the screws are aligned. After this the screws passed through the plunge pool with the wax you can easily get them back out of the Slots are removed. It is sufficient, for example, to keep the chain tight over an edge which is oriented so that it in contact with the screw reaching through the slots benbolzen comes and this, while the chain continues to be moves away, pushes further and further outwards until the coated ones Finally screw it out at a predetermined point Recordings fall out and can be caught.
• the screws are coated in a plunge pool, the height adjustable in one embodiment of the invention ge can be stored.
• the storage can e.g. via two the Un Underside of the basin supporting waves are made, the ends of which are fastened in four slots provided with slots.
• the waves can be in the elongated holes by adjusting screw ben move in the vertical direction, increasing the distance the dip tank can be changed to the conveyor chain. This is necessary, for example, if the system has a time long for partial wax coating of very short screws ben was used, but afterwards longer screws ben are to be partially coated.
• a particularly preferred embodiment provides a height adjustment adjustable plunge pool, which can be heated and thermally insulated is, contains a paddle wheel and in which a bulkhead it is provided that the plunge pool is divided into two chambers Splits.
• the paddle wheel is arranged in one chamber, the wax from this chamber over the bulkhead to the other Chamber conveyed through which the conveyor chain the screws leads.
• the coating process turns this Kam More wax is continuously removed.
• the arrangement of the show felrades in combination with the bulkhead and diving Basin causes, however, in addition to a thorough mixing of the wax furthermore that the wax level is used for coating the chamber remains constant at the height of the bulkhead.
• the paddle wheel slightly more wax in the cam used for coating More promoted than removed from this by the screws becomes.
• the excess wax flows in over the bulkhead back the chamber with the paddle wheel. It is still think bar to train the bulkhead so that it is wholly or partially wise is height adjustable, what a fine adjustment of the Ab enable the wax surface to stand on the conveyor chain would.
• the coating device according to the invention according to FIG. 1 comprises a conveyor chain 10 which is endless over several rollers is passed circumferentially over an immersion bath 11.
• the sub side of the immersion bath 11 is mounted on shafts 12, which in Recordings 13 are arranged.
• the recordings 13 have with Threaded vertical slots for storing the hori zontal shafts 12.
• In the thread of the elongated holes are respectively a lower and an upper set screw 14 is provided which be fixed with a nut 15.
• the distance of the plunge pool 11 can be changed by the conveyor chain 10.
• Tauchbek ken 11 is a paddle wheel 16 with a dashed line interpreted blades 17 arranged.
• FIG. 2 shows further details of the preferred embodiment of the invention.
• a longitudinal one Bulkhead 18 arranged that the basin in a first Kam mer 19 and a second chamber 20 divided. That shovel wheel 16 is arranged in the second chamber 20 and conveyed from this continuously over a stripping plate 17 wax in the chamber 19.
• a part of the chain 10 is with a erfindungsge Moderate receiving device shown in detail.
• the invent proper receiving device consists of an angle th outer tab 21. This has a part 21a, the fulfills the link function in the chain and another thereof angled part 21b with slots 22.
• the slots 22 are used to hold the screws. More resp. Fewer slots can be included, the flap can still be 21 can also be made longer in the chain direction if there is not impaired by the mobility of the chain.
• Fig. 4 finally shows the recording according to the invention direction again from the side.
• the coating of screws with wax is in this one direction very easy. If you follow the process in funding direction of the chain 10, it is first carried out in a known manner Assign a feed of the screws to be coated the side mounts 21. These take the screws by using the side delimiting the slots Divide the screw head while supporting the screws shaft extends down through the slot, and perform it with a previously determined immersion depth the wax located in the chamber 20 of the dip tank 11. Depending on the size and number of screws or the running speed The chamber 19 is characterized by a difference in the ability of the chain removed amount of wax.
• the speed of rotation of the Paddle wheel 16, which is for a subsequent delivery of the wax in the chamber 19, must therefore be adjusted so that that there is always at least a small amount of wax in operation the chamber 19 back into the chamber 20 via the bulkhead 18 flows. Only in this way can the wax level in the chamber 19 in same height with the end edge of the bulkhead 18 con be kept constant.
• One in the conveying direction behind the Plunge pool arranged device, not detailed here is to be described, finally ensures that the screws removed from the receptacles and caught become.
