Uppfinnare: A Broberg Uppfinningen avser en anordning vid manglar med tva over varandra anordnade och i tomgang direkt mot varandra under fjadertryck anliggande valsar och ett under dessa anordnat, andlost transportband for, aterforing av manglat gods till mangelns inmatningssida. For underlattande av atermangling av manglat gods dr enligt uppfinningen en av ett antal brytrullar, Over vilka transportbandet dr fort och medelst vilka detta halles anliggande mot den undre valsen, anordnad bakom och i niva med valsarnas tangeringslinje, sa att vid omkastning av valsarnas rotationsriktning mellan transportbandet och den undre valsen befintligt mangelgods aterinmatas mellan valsarna. Anordningen enligt uppfinningen medfOr den fordelen, att atermangling av mellan valsarna passerat gods kan ske genom reversering av valsarnas rotation, utan att darvid reverseringen maste ske just ogonblicket innan valsarna slappa gods et.
Inventor: A Broberg The invention relates to a device for defects with two rollers arranged one above the other and at idle directly against each other under spring pressure and a breathable conveyor belt arranged below them for feeding back of defective goods to the feed side of the defect. According to the invention, in order to facilitate the re-assembly of defective goods, one of a number of breaking rollers, over which the conveyor belt is fastened and by means of which it is inclined abuts against the lower roller, arranged behind and level with the rollers tangent line, so that when reversing the rollers and the shortage of existing lower roll is re-fed between the rolls. The device according to the invention has the advantage that re-mangling of goods passed between the rollers can take place by reversing the rotation of the rollers, without the reversal having to take place just the moment before the rollers release the goods.
Uppfinningen beskrives i det foljande under hanvisning till bifogade ritning, som visar ett vertikalsnitt genom en. mangel innefattan,de en utforingsform av anordningen enligt uppfinningen. The invention is described in the following with reference to the accompanying drawing, which shows a vertical section through a. lack an embodiment of the device according to the invention.
De bada mangelvalsarna 1 och 2 aro lagrade i gavelhus 3, vilka innesluta lagren jamte fjadrar for den byre valsens 1 paverkan i riktning mot den undre, fast lagrade valsen 2, och aro sinsemellan sammanfogade medelst bultar 4 for att bilda mangelns stativ. Gavelhusen 3 aro vid flitter 5 fastskruvade vid ett underrede 6, som dr forsett med hjul 7 och lampligen utfort av stalror. Mangelvalsarna aro anordnade att drivas av en lampligen pa ett av gavelhusens insida placerad, pa ritningen icke visad, elektrisk motor, som kan startas for rotation at ena eller andra ballet och stoppas med den nedtill pa underredet 6 plac,erade trampan 8. Motor. kan via exempelvis en kuggtransmission driva den undre mangelvalsen 2, medan den ovre valsen 1 kan vara anordnad att drivas av friktionen mot det mellan valsarna passerande mangelgodset eller eventuellt av en mellan valsarnas axlar anordnad, i och for sig kiind kuggtransmission med speciellt langa kuggar for medgivande av variabelt axelavstand. Ett inmatningsbord 9 dr pa vanligt satt anordnat framfor valsarna 1, 2. En andlos duk eller ett transportband 10, som aven kan tankas ersatt av flera ph in-hordes avstand jamlopande band, dr fort Over brytrullar 11, 12 13, sa att det anligger mot undre halften av den undre valsens 2 omkrets. Av brytrullarna dr den lagst placerade anordnad som spannrulle for transportbandet, genom att dess lagringspunkter 15 aro paverkade av vid underredet 6 fastade skruvfjddrar 16. Transportbandet 10 kan vara anordnat att drivas av friktionen mot den undre valsen 2 resp. det av denna framforda mangelgodset, men dr lampligen anordnat att med en hastighet ungefar motsvarande valsarnas periferihastighet drivas av en ay brytrullarna, exempelvis den owe 11, som da dr kopplad till drivmotorn exempelvis via den undre valsen 2. I bekvam arbetshojd under inmatningsbordet 9 dr en uppsamlingsskal. 17 for manglat och av transportbandet 10 avldmnat gods 18stagbart fastsatt vid underredet 6, genom att den med krokar 18 kan gripa om med underredet 6 fast fOrbundna tappar 19. Uppsamlingsskalen 17 dr ldmpligen utford ay rostfri plat. The two deflection rollers 1 and 2 are mounted in end housing 3, which enclose the bearings and springs for the action of the byre roller 1 in the direction of the lower, fixed bearing roller 2, and are joined together by means of bolts 4 to form the deflection stand. The gable housings 3 are screwed to the chassis 5 by a chassis 5, which is provided with wheels 7 and is suitably made of racks. The defective rollers are arranged to be driven by an electric motor located on one of the gable housings, not shown in the drawing, which can be started for rotation at one or the other ball and stopped with the pedal 8 placed at the bottom of the chassis. can drive the lower defect roller 2 via, for example, a gear transmission, while the upper roller 1 can be arranged to be driven by the friction against the defective material passing between the rollers or possibly by a tooth transmission arranged between the shafts, per se with a particularly long teeth for allowing of variable wheelbase. A feed table 9 is usually arranged in front of the rollers 1, 2. A breathless cloth or a conveyor belt 10, which can also be refueled replaced by several ph in-hordes spaced apart belts, where fast Over break rollers 11, 12 13, so that it abuts towards the lower half of the circumference of the lower roller 2. Of the breaking rollers, the lowest position is arranged as a clamping roller for the conveyor belt, in that its bearing points 15 are affected by coil springs 16 attached to the chassis 6. The conveyor belt 10 can be arranged to be driven by the friction against the lower roller 2 resp. the defective goods conveyed therefrom, but which is suitably arranged to be driven at a speed approximately corresponding to the peripheral speed of the rollers by an ay breakers, for example the owe 11, which is then connected to the drive motor, for example via the lower roller 2. At a comfortable working height below the feed table collection shell. 17 for missing and disassembled goods 18 removed from the conveyor belt 10 attached to the chassis 6, in that it can grip with hooks 18 firmly connected pins 19 with the chassis 6.
Anordningen fungerar vid mangling sa, att det pa inmatningsbordet 9 infijrda mangelgodset 14, efter passerandet mellan valsarna 1 och 2, gripes av transportbandet 10 och ddrigenom bringas folja den undre valsens 2 omkrets till den punkt yid mangelns inmatningssida, ddr transportbandet 10 lamnar valsen 2. Ph grund av sin tyngd foljer mangelgodset darefter transportbandet Over den framre brytrullen 12, men laninar sedan transportbandet 10 och glider ned i skalen 17. For den handelse mangelgodset haftar yid den undre valsen 2 och icke av sin tyngd lamnar denim, lossas det frau valsen 2 och fores ned pa transportbandet 10 av en vid valsens framsida anordnad ledplat 20. Om mangelgodset 2— — skall foras saval fram som Ater mellan valsarna, underlattar transportbandet mangling-en darigenom, att reversering av mangeln ken site aven efter det godset helt passerat mellan valsarna, eftersom darvid transportbandet ombesorjer aterinmatningen. The device functions in the event of a defect so that the defective goods 14 introduced on the feed table 9, after passing between the rollers 1 and 2, are gripped by the conveyor belt 10 and thereby the circumference of the lower roller 2 is brought to the point on the feed side of the defect. Due to its weight, the defective material then follows the conveyor belt over the front breaker roller 12, but then lines the conveyor belt 10 and slides down into the shells 17. and is lowered onto the conveyor belt 10 by a baffle 20 arranged at the front of the roller. , since the conveyor belt takes care of the re-feeding.
