Definitions

  • the invention relates to a motor drive according to the The preamble of claim 1, wherein the rotational movement of the Drive shaft in a reciprocating linear motion is implemented.
  • Such a motor drive is preferably used in a Pass-through dishwasher used in which goods to be washed by a jack transport through the various Treatment zones of the machine such as pre-wash zone, main wash zone, Rinse zone, drying zone is transported.
  • the dishes is used in washware containers (baskets).
  • the Washware containers are designed so that the pawls of the Intervene jack transport and intervene in the movement of the Jack transport rail can be taken. When returning the Jack transport rail fold the jacks and the The handle transport rail runs empty under the washware container by. So that the wash ware with the wash ware containers is completely through the machine is transported are several single strokes required.
  • the drive via crank arm is such that from one Motor a rotating drive shaft, usually over a Gear transmission, protrudes upwards and has a bearing a turntable is connected, which is eccentrically on Outer circumference a projecting pin or the like.
  • This drive pin is in one straight U-rail, which is transverse to the longitudinal movement of the Transport rail runs. The rotation of the drive shaft will this results in a reciprocating linear movement of the Transport rail implemented.
  • Transport rail can cause significant forces that too Hazards to fragile goods in transit, but also to Operators can guide. The forces that occur must therefore be limited.
  • the invention has for its object a motor drive According to the preamble of claim 1 so that the transverse forces occurring to the longitudinal axis of the drive shaft regardless of the location of the transmission facilities in a linear movement, such as a transport rail, and with can be reliably limited with little technical effort.
  • the motor drive is said to make minor changes to the most existing systems can be adapted.
  • the drive shaft is off two partial shells with a semi-cylindrical cross-section existing warehouse provided that with a switching device that interacts when a certain limit is exceeded lateral deflection of at least one partial or half shell switches, in particular switches off the motor drive.
  • the lateral deflection can be done via external lateral Bearing plates on a side arranged next to it Switching device, in particular with a push button, be transmitted.
  • the release force can be adjusted accordingly Preloading the partial shells of the bearing easily and precisely adjust, for example via fastening bolts on which Compression springs are screwed adjustable. At least on one These plates are in place with a stationary facility connected to the overall system.
  • a limit switch bracket or one Limit switch holding plate and a limit switch release plate or a limit switch trip plate is provided on or on which is a limit switch which, if the preset force triggers.
  • FIG. 1 On the left side of Figure 1 is the schematic Jack drive with the upper end of the drive shaft 20, the attached to a turntable 60 and below the Transport rail 70 arranged is shown in dashed lines.
  • a U-shaped straight channel 72 at the bottom of the Transport rail 70 receives a cross bolt 62 which on The outer circumference of the turntable 60 is fixed and at the rotation of the transport carriage 70 back and forth reciprocated. Due to the forces involved, this can Items to be washed can be damaged or destroyed in the event of incorrect operation the operating personnel can also be endangered. This can be prevented by measures as described at the beginning is.
  • FIG. 2 shows a cross section through the transport rail 70 shown, on which the foldable hook 74 are arranged, the washware container 80 in the direction Move the dishwasher.
  • Figure 2 also shows stationary lateral limiting rails 82 for the washware containers 80.
  • FIG 3 shows the motor 8, generally designated 10 Motor drive, a common motor mounting 21 for the Turntable 60.
  • the engine mount 21 is fixed with connected to the stationary device of the machine.
  • Figure 4 shows the invention from a left and a right half-shell 22, 24 existing bearings for the rotating Drive shaft 20, each by a lateral Bearing plate 30, 32 are limited.
  • a screw bolt 44 is passed through to the machine, on the left side carries a compression spring 43, the Pressure is adjustable via the adjusting nut 47.
  • the power for the forward and reverse of the Transport rail 70, which over the engaging pin 62nd is initiated, supported with the bias of the springs. If the pretensioning forces are exceeded, they shift the half shells.
  • FIG. 5 on the one shown in FIG Front view shown clearly shows the two Half shells 22, 24 for the drive shaft guided between them 20, the support 46 of the bearing shells to the machine is arranged between the two half-shells, which by two bolts 44 over compression springs 43, 45 and adjustable nuts 47 are pressed together.
  • the Bearing plate 32 is bent laterally in an L-shape and contains a trigger switch 28 mounted thereon Switching device and trigger button 29.
  • Figure 6 differs from that Representation of Figure 4 essentially by the additional Arrangement of a right bolt 44 respectively an extension of the left bolt with its own Compression spring 43 'and its own adjusting screw 47.
  • the bolts are in the support 46 attached to the machine. This allows the preload for the left bearing shell 22 on the left springs and for the right bearing shell 24 separated on the right springs can be set.
  • FIG. 7 The top view of FIG. 7 on the representation of the in FIG. 6 shown bearing sees two adjacent left and right independently adjustable compression springs for the triggering forces in the working stroke and in the return idle stroke in front.
