DEVICE FOR CUTTING BREAD OD.DGL. INTO DISKS

The invention refers to a device for cutting bread od.dgl, in disks. Such a device exhibits a gumption rack as well as a number of relative to the gumption rack hinund moved measurers, that divide them by a feed organ supplied bread od.dgl, in disks. The measurers move in to each other parallel levels and are arranged at least one framework. The framework is moved by an engine and a crankshaft-and-connecting-rod drive. Devices of this kind are well-known in many Ausflihrungsformen. The framework of a group of measurers is either over a parallel guide with that gesture] - [coupled or he is endanggeführt at a guide way. All these well-known designs have the disadvantage that they work because of the many joints in the transmission or suspension only with relatively low speeds. If the speed were increased, the wear increases disproportionately. Besides balancing is complicated, complex and thus expensive with the well-known constructions. It is the task of the Erf'mdung, a device for cutting bread od.dgl to create with which the cut speed is in relation to the well-known construction substantially more highly. In order to make possible, the invention plans that each framework with that or the connecting rod (n) of the crankshaft-and-connecting-rod drive rigidly connected and in the proximity of the inertia center of the mass formed by connecting rod, framework and measurer is tiltable stored, whereby the drag axis parallel to the crank axle is essentially straight-lined led relative to the gumption rack. On this device according to invention it is possible to cut bread without having to lubricate the measurers. The latter is necessary at low speeds, because otherwise bread at the sides of the measurers adheres. Furthermore it became possible by the ErPmdung, warm bread, to freshly cut i.e. from the furnace coming bread. Thus that the framework is rigidly connected with the connecting rod, it is omitted the unfavorable joints. The connecting rod and the framework with the group of measurers is to be understood thus as a unit, which unit is set directly by means of the crank from the engine in motion. The invention uses the realization that, if a body at any point is exposed to an impact outside of its emphasis the body turns not around its emphasis, but around its inertia center. If now, as during the device according to invention, a framework with connecting rod is propelled by a crank: the free end of the connecting rod will describe a circulation, which can be divided into two directions, i.e. a unit going and perpendicularly to it an arranged managing mentioned by the emphasis that. The movement arranged by the emphasis is hiebei as hinund the working cut movement, to understand which the measurers would drive out, and whom movement perpendicularly to the same as one hinund working rotation or oscillation around the Rir each unit empirically or inertia center which can be determined by computation. This center becomes a straight-line movement ausfiihren due to aufund the abwärtigen cut movement, possesses however the large advantage that with at the steep one concerned will not arise suspension reaction force arranged which can be arranged transverse to the cut movement. The absence of the ReaktionsIcraft means thus an extremely wearful suspension. It will also be clear that balancing the moved parts needs to extend only to the crank mechanism on the drive shaft of the engine. As favourable arrangement of the invention is suggested forming the Schweukachsenführung by the deflection movement of a leaf spring between frameworks and rack essentially perpendicularly to the Schnlttebenen extended. If as suspension at the framework a such smooth joint is used in form of a leaf spring, their sheet perpendicularly to the cut movement extended, becomes a still better vibration-free and noiseless device obtains. Hiebei proves it as favourable, if the leaf spring is connected with the framework in its center and falls themselves at their ends at the rack. In a preferential execution form of the device according to invention, which exhibits two measurer-equipped frameworks, whose movement phases are against each other transferred by 7r and whose measurer on gap is arranged, whereby between two measurers each the way of a feed tappet lies, rings the way of the drag axis of the frameworks determined by the mass distribution completely within the range between • the crank and the way of the feed tappets. Owing to this arrangement of the leaf spring the measurers within their framework lead not nttr one aufund outgoing Schneidebewegtmg, select at the same time toward the article which can be cut seen cutting movement forward. This results in the large advantage that with that so far well-known devices the pressure plate, which holds bread which can be cut at its place this used, kind can escape. During the cutting downward movement of the measurer penetrates the knife more deeply into bread, while it separates during the upward motion from the Schnittspalt. The function of the pressure plate above bread is taken over in this way by the measurers themselves. The description of the invention is abgepaßt on the basis the designs. Represent: Fig.1 a cut of the effindtmgsgemäßen bread cut device, after which line II in Fig.2, Fig.2 a cut of the same 3 NR,334003 device after the line II-II in Fig.1, Fig.3 an opinion of the frameworks with associated Messergru£pen, in which the movement of the measurers is represented during the cut procedure. The Ausffthrungeform of the Schneidevorrlchrung according to invention represented in the designs is generally used standing fashion]] bread cut device. This type device works with two groups of measurers --1, 2--, whereby each group within an own framework --3, 4-- is set in. Each framework --3, 4-- is rigid over one to the same fastened connecting rod --5 and/or 6-- with a crank --7-- on the AbtriebsweUe of an electric motor --9-- coupled. The crankpins --7 and/or 8-- are against each other transferred by 180°, so that with the rotation of the cranks by the electric motor --9-- the frameworks --3 and/or 4-- at any time movements directed each other opposite would drive out. Each group of measurers --1, 2-- covers an amount of parallel, vertically arranged measurer. Each knife consists of an oblong thin narrow sheet, its lower end over a yoke --10-- to the lower bar of the associated framework is fastened, while the upper end in a tiltable yoke --la-- in the upper bar of the framework is hung up. The yoke --11-- is at his other end by a compression spring --12-- it loads in such a manner that the measurer sheet of nnter pre-loading stands. The application of this Jochaufhängung makes it possible, the measurers of both groups --1, 2-- to arrange alternating next to each other, as evident from the Fig.1 and 2. Each framework --3, 4-- is with his lower bar at the center of a leaf spring --13-- fastened, along the level by the framework extends and with its ends at a horizontal bar rectangle --14-- , that falls the two frameworks --3, 4-- surround. The bar rectangle --14-- rests over shock-mounts --! 5-- on bars of the rack --16--. The leaf spring --13-- a such form (s.Fig.1) possesses that this permits one by the crank determined vertical excursion of the center of the feather/spring. Bread which can be cut, that by a dotted line --17-- in Fig.2 is represented, rests on a plattenförmigen carrier --18--, which forms a part of the rack. Above and along this plate --18-- is a printing organ --19-- perpendicularly to the level by the frameworks --3, 4-- adjustably. The impact of the device is the following: By running the engine --9-- become the cranks --7, 8-- fast rotate, so that at the same time the lower ends of the Sehubstangen --5, 6-- a fast rotation to be suspended. By a correct distribution of the masses of each unit, i.e. the group of measurers, the framework and the connecting rod the inertia center lies in the height of the upper surface of the lower bar of the frameworks --3 and/or 4--. This point is only straight-lined vertically moved. The measurers become not only a straight Aufund downward movement, but in addition also a tilting motion ausführe.n, which movement is represented in Fig.3 in increased yardstick. From this figure it is evident that the lower ends of the measurers, those almost with the Außängepnnkt of the framework at the leaf spring --13-- lies, a straight Aufund downward movement would drive out, while the upper ends of the measurers describe a horizontal Hinund moving at the same time. The upper ends of the measurers go through an elliptical course, those in Fig.3 also --34-- designation and something is exaggerated represented, in order to show the Schueidebewegung of the groups of measurers more clearly. The cranks of the engine turn in a such direction that the measurers cut during the downward movement bread and during the upward motion withdraw themselves and from the Schnittspah loosen. The advantage of this cut movement is, da/3 now no more in former times necessary pressure plate --37--, which is represented dotted in Fig.3, is necessary, around bread during the cut procedure on the carrier --18-- to hold. The measurers take over this function, because bread during the cut procedure continual downward, i.e. on the carrier --18-- one presses.
