Definitions

  • the invention relates to coupling devices for so-called power and free towing circuit conveyor with trolley, which on below the towing device, for.
  • B. a continuously revolving conveyor chain or individual running on motor tracks, arranged overhead conveyor can be moved and each have a driving head and a release head for cooperation with the coupling devices attached to the towing device.
  • Such a coupling device for coupling and uncoupling the trolley is described, for example, in DP 26 50 031. It has a driver lever which can be released in a controlled manner and a trigger lever which is operatively connected to it and is pivotably mounted, both of which are articulated to one another via a further toggle lever consisting of handlebar and crank.
  • the driver lever and release lever protrude into the movement path of the organs located on the trolley - driver head and release head.
  • the coupling device has four movably mounted, interconnected levers with a corresponding number of articulation points. All four bearing axes of the Articulation points are transverse to the conveying direction and are also subjected to bending when coupling and uncoupling.
  • the invention is based on the technical problem, while avoiding the shortcomings indicated, of creating a coupling device with only two movable coupling parts, the storage of which is practically wear-free and the method of operation largely avoids rattling noises with the greatest possible safety.
  • the coupling device K consists of two identical coupling shoes 10 and 11, arranged in mirror image, which are supported on the axis 9 with tabs bent at right angles and which, as illustrated in FIG.
  • the coupling jaws 10 and 11, which are designed as sheet metal parts of essentially L-shaped cross section, are provided with bevels 10 "and 11" at both ends of their interacting horizontal webs 10 and 11 'and have recesses 12 and 13 in the central region, respectively extend into the vertical web.
  • the bevels 10 "and 11" of the two clutch shoes together form a V-shaped ramp R or R ', while the recesses 12, 13 together form a rectangular pocket T.
  • the movable on the track 2 trolley 3 consist of a front and a rear roller carrier 14 and 15 with the rollers 16 and 17 and a U-shaped tube bracket 18 connecting the two roller carriers.
  • the front roller carrier 14 in the conveying direction F carries a short Carrying head 19 of suitable length in the pocket T and the roller carrier 15 in the conveying direction an approximately four times as long a trigger head 20.
  • the driving head 19 and trigger head 20 are preferably made of a material which has good sliding and noise damping properties.
  • the operation of the drag circuit conveyor is as follows:.
  • the driving heads 19 of the two trolleys 3 running one behind the other are located in the pockets T of the coupling devices K, so that the trolleys are moved in the conveying " direction by means of the conveyor chain 4.
  • the trolleys are by hand or automatically controlled switches out of the conveyor track, the driving head 19 sliding out of the pocket T of the coupling device K.
  • uncoupling also takes place when the towed trolley 3 with its front roller carrier 14 on the rear roller carrier 15 one on the conveyor route stationary trolley 3.
  • the release head 20 of the stationary trolley enters the front ramp R and laterally pushes the coupling jaws 10 and 11 outwards so far that the pocket T is opened and the driving head 19 of the pulled trolley emerges from the rear of the coupling device
  • the release head 2 0 is longer than the pocket T, the opened coupling device K passes over the release head 20 of the stationary trolley.
  • it arrives in the area of the driving head 19 of the stationary trolley, which in turn now enters the ramp R and laterally urges the clutch shoes 10 and 11 until the driving head 19 finally reaches the area of the pocket T and because it is shorter is as this pivot the clutch shoes 10 and 11 under their own weight back into the closed position, and take the trolley over in the pocket T locked driving head 19 with.
  • each coupling device K overflows all of the pent-up trolleys to the very front, so that the trolleys are taken one after the other.
  • the modified coupling device according to FIG. 3 differs only insignificantly in construction and mode of operation from the previously described device.
  • the coupling jaws 21, 22 are essentially flat sheet metal parts which are mounted on the axis 9 with tabs bent at right angles and which have bevels 24 inclined at both ends toward the centrally provided recess 23.
  • the driving head 19 and the release head 20 'of the trolley 3 as shown in FIG will.
  • the coupling device according to the invention has both structural and functional advantages. It consists of a few easy-to-manufacture parts, which only have to perform simple movements about a longitudinal axis, which do not require springs or locking levers, and which thus ensure the greatest possible safety. With guide rails to be attached to the side of the chain channel or other supporting parts, absolute safety against unintentional uncoupling can be achieved in particularly vulnerable sections, which is not possible with coupling devices with moving parts that move in the conveying direction.
