Definitions

  • mills are provided with a series of large flaps or doors pivotably hinged to the machine housing, via which the inside of the mill, in particular the rollers and the screens, is accessible for inspection, cleaning and repair purposes.
  • These are access doors which are generally used in machine and apparatus construction for similar purposes, which are hinged to hinges and can be locked on the edge opposite the hinges by means of commercially available rotary lever locks.
  • Usually only such a closure is provided; in exceptional cases, however, such as in the case of doors with a particularly large area, two such locks are occasionally used, which are generally to be operated individually or in succession.
  • Unauthorized opening of the doors should be avoided for safety reasons - locks or corresponding screw connections that can be actuated using a separate socket wrench are also used.
  • Devices of this type are known as so-called six-roll mills.
  • six-roll mills In their basic structure they are described in DE-PS 236 485 and US-PS 4,225,093. Characteristic of these mills are essentially three pairs of rollers arranged in a triangular configuration and two mostly multi-layer screening devices, the upper of which covers approximately the area from below the first to above the second pair of rollers and the lower approximately the area from below the second to above the last pair of rollers. Most of the time, the first and the last pair of rollers lie approximately one above the other in a vertical line, while the middle pair of rollers is located in an intermediate plane and laterally offset by the length of the screening devices.
  • the invention in a device according to the preamble of claim 6 is intended to enable it to be attached to other parts without the flow of force being disturbed or being transmitted to these parts.
  • the features of claim 3 represent a practical design of the individual locking points, the movable locking elements being arranged in the form of bolts in a practical manner within the machine housing, where there are more favorable spatial conditions for accommodating the mechanics required for mobility with simultaneous weight relief the flaps or hoods of this mechanism.
  • the malt grist mill shown in Fig. 1 consists essentially of two upstanding from a base plate 1 supporting columns 2 of the machine housing 3, between which three roller packages 4, 5 and 6 formed as self-contained units by indicated screw connections 4 ', 5', 6 ' are fixed (see also FIG. 2) and from two screen units 7, 8 arranged between the second roll package 5 and the lowermost roll package 6, with a counter-rotating drive 9.
  • the material to be ground is fed to the roller package 4 via a feed roller 18 and a guide plate 19, where it - like in the subsequent roller package 5 - is crushed.
  • the meal is evenly distributed by a distribution device 20 to the two sieve units 7 and 8 or their sieve compartments 10 and 12, where semolina and flour portions are already sieved, while the husks remain above the sieve surface (cf. also FIG. 10).
  • This process continues in the lower sieve compartments 11 and 13, after which flour is finally drawn off through the outlet shafts 21 and 22 and through the shafts 23 and 24 husks.
  • the semolina reaches the lowest roller package 6 via guide devices 25, 26, where they are also ground to flour.
  • the arrangement of the sieve units is such that the sieve unit 7 on the one hand on two identical link levers 27, 28 (Fig. 3, 4), which in turn are connected with corresponding drive levers 27 ', 28' and in an extended area 2 'of the columns 2 of the machine housing 3 are pivotally mounted, is arranged hanging; on the other hand, the sieve unit is supported by two further articulation levers 29, 30 such as to support swinging outgoing arms (not shown) relative to, for example, the extended region 2 'of the columns 2 (FIG. 5).
  • the articulation of the sieve unit 8 is designed in an analogous manner, that is to say with corresponding articulation levers 31, 32 and drive levers 31 ′, 32 ′ associated therewith, and articulated levers 33, 34 arranged “standing”.
  • each of the sieve units 7, 8 the center of gravity is approximately the same distance from all of their articulation points and in a plane with these (FIGS. 1, 3), namely the center of gravity 35 of the sieve unit 7 with respect to the lower articulation points of the levers 27, 28 and the upper articulation points of the levers 29, 30 and the center of gravity 36 of the sieve unit 8 with respect to the lower articulation points of the levers 31, 32 and the upper articulation points of the levers 33, 34. All of these levers have restoring forces due to their storage in rubber spring elements, which is yet to be described which, in the rest position, that is to say when the drive 9 is not switched on, bring about a vertical position of all the levers.
  • the push rods 42, 43, 44 and 45 are provided with fork-shaped dropouts 42 ', 43', 44 'and 45' for detecting the specially designed ends of the link levers 27 ', 28', 31 'and 32' (see Fig. 4) and each supported by means of a ball bearing 50 on the eccentrics 38 to 41. Key connections 51 ensure simple axial adjustment of all eccentrics.
  • the simple articulation levers 29, 30, 33, 34 which do not serve to drive the sieve units 7, 8, are designed in a similar technology, as can be seen in FIG. 5 from the example of the articulation lever 29.
  • the flange 74 is screwed to the machine housing and the flange 72 to the sieve unit 7.
  • rectangular recesses are provided, through which the hooks 197 pass or which surround the flanges 197' of the hooks.
  • displaceable latches 198 are provided, one each in the zones of the edge region 191 'adjacent to the pivot axis and two in the part of the edge region 191' opposite the pivot axis.
  • the bars 198 are designed as flat profiles which are guided by means of longitudinal slots 199 on the machine housing 191 or the edge region 191 'fastened pins 200 longitudinally.
