Definitions

  • a radiation heating element for cooking purposes has become known in which helical heating resistors are attached to the surface of an insulating material consisting of a pressed silica airgel by means of U-shaped clamps which are driven into the carrier material. These clips are attached by means of pneumatically operated clip-setting devices, also called nailers below, which are guided and operated by hand. This is not only very time-consuming, but requires qualified workers who have to work with great care, because otherwise either damage to the support layer or improperly driven clips and thus the possibility of short-circuits in the operation of the heating element are given.
  • the object of the invention is to provide a method and a device with which the attachment of the heating resistors is facilitated by means of brackets and preferably also enables automation.
  • the heating resistors can be pre-positioned outside of the carrier area in their final form, for example a spiral course.
  • the application tool is then brought up to the carrier so that the heating resistors assume their desired position on the carrier.
  • the clamps can then be placed using clamp guide means.
  • the clip guide means can be formed directly by parts of the clip setting device, ie contain a guide or shot channel of the setting device.
  • the attachment tool could already contain several clip-setting devices at the intended locations. Since in such an embodiment the staple feeding to so many staple positions is quite complex, it can be useful to move one or more staple setting devices by hand or by automatic handling devices (industrial robots) to the staple guiding means, which in this case position the staple setting device.
  • the attachment tool contains only part of the firing channel.
  • the staple guiding means can be bores or sleeves in the application tool, to which the nose of the nailer containing the firing channel only has to be fed relatively roughly.
  • the nailer then positions itself or the clip properly.
  • an elastic insertion aid which is otherwise provided on the nailer, for example two spring plates compressed at their tips, can be provided on the attachment tool.
  • the helix looks for the right position by sending it away from the spring plates formed tip between the turns of the heating coil, engages and if necessary moves axially.
  • the clamp is therefore always placed between two heating coil turns over the wire section resting on the carrier.
  • the firing channel itself can also be integrated in the attachment tool, and the nailer can only use his drive and the staple feed e.g. with a shortened nose, to be positioned over it.
  • the heating coil guide can consist of a corresponding guide groove, in the area of which the heating coils are held, for example, by magnetic force.
  • the attachment tool is designed so that the magnetic force is weakened when lifting so that it becomes weaker than the holding force of the clips, so that the heating coils remain on the carrier when the attachment tool is lifted off.
  • Heating elements especially radiant heating elements, which are produced by the method according to the invention. They differ from other heating elements in that the clamps are repetitively regular and precisely aligned. With them, the heating resistor can be attached directly and without an intermediate layer on the surface of a very little abrasion-resistant carrier pressed from powder-like material.
  • an electric radiant heater 11 which is arranged, for example, for heating a hotplate below a glass ceramic plate 10. It contains, in a sheet metal shell 12, a carrier made of highly heat-resistant insulating material, in particular a slightly compressed molded body made of a very light pourable, mineral insulating material such as fumed silica airgel. This material has very good thermal insulation properties with good heat resistance, but with low mechanical strength properties and low abrasion resistance.
  • the material is introduced into the sheet metal shell 12 as bulk material and pressed there with a stamp or introduced as a pre-compact where it forms a layer, ie a flat bottom 15.
  • a peripheral edge 14 is inserted after the helix attachment by a separate ring made of material with better mechanical strength properties, such as fibrous insulating material (Fiberfrax). It is also possible to attach the heating resistor to a carrier outside the sheet metal shell and to insert the resulting unit.
  • a separate ring made of material with better mechanical strength properties, such as fibrous insulating material (Fiberfrax). It is also possible to attach the heating resistor to a carrier outside the sheet metal shell and to insert the resulting unit.
  • brackets 20 are driven at intervals between the spiral windings 18, which are essentially U-shaped and engage with their two free legs in the carrier material. From Fig. 2 it can be seen that the brackets are set somewhat obliquely to reach between two turns 18.
  • a clamp arrangement which extends over an upper section of the heating resistor and thereby encloses practically the entire coil, is possible, but less advantageous, because it does not allow reliable axial fixing and receives greater self-heating.
  • the heating coils can be arranged in the usual way in a spiral or in another pattern on the surface 17 and preferably lie in slight groove-like depressions.
  • the arrangement on the surface and the definition only by means of the brackets is also possible.
  • One or more heating resistors per radiant heater can be provided.
  • Fig. 3 shows an attachment tool 21 which has the basic shape of a disk which fits into the interior 22 formed within the sheet metal shell 12 of the radiant heater. It has on its upper, essentially flat working surface in FIG. 3 23 guide means 24 in the form of grooves or grooves which are designed in accordance with the desired spiral course of the heating resistors and accommodate the heating resistors 16 therein.
  • the application tool is made of a disc 30 made of non-ferromagnetic material, e.g. Gunmetal, and a disc 31 made of ferromagnetic material.
  • magnets 45 are arranged below the guide means or grooves 24 on the disc 31 in recesses of the disc 30, which hold the heating elements 16 in the grooves with a predetermined force that is sufficient, in order to keep the heating resistors in the groove when they are upside down.
  • Other types of fastening are also possible here, for example slight lateral clamping in the groove or the like.
  • clamp guide means 25 are provided at intervals from one another, which in the present example have openings which pass through the attachment tool designed as a double disc.
  • a sleeve 27 is inserted, which holds resilient positioning plates as the positioning device 28.
  • These positioning plates are two resilient plates which run parallel to one another and which are fastened to the sleeve 27 in the region of the lower collar in FIG.
  • the positioning device 28 thus formed is arranged under such a slope that its tip can grip between two turns 18 of a heating resistor.
  • the gap 29 which is formed between the two metal sheets and is closed when it is inserted is arranged such that it lies just below the working surface 23.
  • the attachment tool 21 is in the position shown in Figure 3, i.e. with the working surface 23 facing upwards, with the heating resistors 16 prepared for insertion, by inserting them into the grooves 24. They are fixed there by the magnets 45 held between the two disks 30, 31.
  • the lower disk 31 is made of ferromagnetic material and serves as a magnetic holding disk or as a yoke.
  • the resilient positioning device 28 ensures that its wedge-shaped tip engages with the gap 29 between two heating coil turns 18. An additional relief for the even insertion of the heating coil into the grooves 24 could be achieved if the positioning device 28 is moved out of the area of the groove 24 during the insertion by mechanically withdrawing the plate 31 with the sleeves 27 downward.
  • the positioning device After insertion, the positioning device is then retracted into the groove area and is threaded between the turns, e.g. this can be made even easier by applying a vibration to the attachment tool. Whether this additional measure is necessary depends on the spiral pitch and the flexibility of the heating resistors.
  • the attachment tool 21 is then pivoted through 180 °, for example by a schematically indicated pivoting device 46 (FIG. 4), and is placed with the working surface 23 down on the surface 17 of the carrier 13.
  • a schematically indicated pivoting device 46 FIG. 4
  • the heating coil can be pressed into the surface 17 of the carrier 13 at the same time, so that they are already from itself receives a certain lateral guidance.
  • Such a groove 33 in the carrier can also be provided when the carrier material is pressed. If the groove 24 is approximately as deep as the helix diameter, the heating resistor is arranged on the surface 17.
  • the nail nose is wedge-shaped at its end corresponding to these sheets. It reaches through the opening 26.
  • the slot 29 opens slightly and a U-shaped bracket 20 is driven into the carrier 13 through the shot channel 35 and the guide channel 40 between the spring plates.
  • Both the transverse positioning of the nail nose and its height position are determined by the engagement in the clamp guide means 25.
  • the surface 37 adjoining the nose 36 can rest against the sleeve 27 in the correct positioning. It is also possible, for example, to determine the orientation of the nailer by means of a cooperating profile on the nailer and attachment tool in such a way that the clamp 20 is set at the correct incline (FIG. 2) corresponding to the helix pitch.
  • an automatic handling device industrial robot
  • any other to remove the nailer 34 mechanical device.
  • a corresponding number of the clamp guide means 25 are provided, which are operated in succession by the nailer.
  • the application tool is lifted off again, the heating resistor, which is now held by the clips which have penetrated into the carrier, being released from the grooves.
  • the ferromagnetic plate 31 is lifted, on which the magnets adhere, so that the magnetic force acting on the heating resistor is reduced or canceled. After turning the application tool, it can be loaded again.
  • Fig. 5 shows a particularly simple embodiment, where the clamp guide means each consist of a hole in the attachment tool 21 and a positioning device 28 ', which consists of two spring plates, which are attached to the working surface 23 opposite surface of the attachment tool 21 and in the area the opening 26 to run in a V-shape.
  • Fig. 6 shows an embodiment in which the clamp guide means 25 b in a sleeve 27 b contain part of the shot channel of the nailer.
  • Positioning devices 28 are again provided on the underside of the sleeve in the form of two spring plates which are pressed together and pressed together in a spring manner.
  • the nailer 34 has a shortened shot channel 35 a and the driver 37 of the nailer, ie the tool that moves the clip down in the shot channel, penetrates into this extended shot channel 35 b in the sleeve 27 b and drives the clip 20 in their final position. It must be ensured that the weft channels 35 a in the nailer and 35 b in the sleeve are well aligned, for example by centering means, not shown, between nailer 34 and sleeve 27 b.
  • This embodiment would also be suitable for use on the nailing tool provided with nailing tools, the nailing nose instead of the sleeve 27b reaching into the end position.
  • This version is very advantageous for particularly economical series production if the number of clips is not too large.
  • FIG. 7 the shot channel 35 b can be seen with insertion bevels.
  • This version is very advantageous for the automatic guidance of the nailer because the nailer must be guided by a handling device 48 (FIG. 6) only in one plane and the nailer nose does not have to be immersed in the attachment tool.
