Device for transferring bearing shell-like workpieces from a delivery location to a further location.

The invention relates to a device for transferring individual, Bearing shell-like workpieces, in particular connecting rod bearing caps, from one delivery location to another, for transfer to a processing machine suitable transfer layer,

whereby in the delivery system of the workpieces, both of them are at the open workpiece side at a distance from one another, the support or separation surfaces are essentially horizontal Level and in their transfer position are essentially in the vertical plane and face the processing machine, with an actuating mechanism for changing the position of the workpieces, one of which can be driven by means of a drive device Has slide, with the help of which the respective workpiece along a transport path in the direction of the processing machine can be transported to a transfer point.

A device with the structural features of the construction described above is already known (see feeder from W + M, Automation Karl Müller). With their help, connecting rod bearing caps can be transferred from their delivery position, in which their legs are directed downwards, into a processing position, in order to be able to make a screw hole in each of their support or parting surfaces with the help of a corresponding boring machine. The slider of the operating mechanism of this known device is Settin g in the horizontal plane from a transfer position in a Übergabest ^ controllable, said slider having a ve about a horizontal pivot axis ^r pivotable turntable, whose axis of rotation in one SChv / enkendlage, ie, in the transfer position of the Slide, in the horizontal plane and in its other pivot end position, or in its transfer position, is in the vertical plane. In the takeover position of the turntable, the connecting rod bearing caps are individually brought into contact with one of their end faces on the turntable, whereupon the turntable is pivoted through 90 ° about its horizontal pivot axis. Accordingly, there is

the connecting rod bearing cap taken from the turntable after the Pivoting movement of the turntable in a position changed by 90, i.e. the face of the conical bearing cover resting on the turntable is in a horizontal plane. After the turntable has been swiveled 90 degrees, the slide that carries it becomes transported in the direction of the boring mill producing the screw holes, but after the 90-degree pivoting has taken place the connecting rod bearing cap whose contact or parting surfaces are now on the side facing away from the boring mill. The position of the connecting rod bearing caps must accordingly be changed again in such a way that their supports or parting surfaces pointing legs to the liohrwerk. This change in position is brought about by the fact that the turntable also executes another 180 rotation around its axis. The 180 turn is superimposed on the 90 turn.

The actuating mechanism of the known device thus has a total of three different movements, namely a linear movement his sled, a swiveling movement of his turntable and to perform a self-rotation of the latter, in particular the necessary pivoting and rotating movement of the Turntable including the? Itsprechondt :? Drive mechanisms overall to require a finite and correspondingly expensive construction.

The invention is now based on the object of converting a device which is distinguished by a simple structure individual bearing shell-like workpieces from one delivery system to another for transfer to a processing machine to create a suitable transfer layer that can be used to change the position of such workpieces with fewer movements or

Here one becomes this fork, what the mutual distance their fork arms, choose in relation to the shape and dimensions of the workpieces to be handled in such a way that the Workpieces after they have tipped over with their one side of the workpiece as well as with their support or separation surfaces before the Overturning come to rest on the conveyor belt. The distance between the fork arms is therefore to be chosen so that especially for The conrod bearing caps cover the fork arms and hold them between them in the tipped position, i.e. in their transfer position. Here it is advantageous if at the rear end of the fork at least one stop surface extending upwards from the fork it is provided on which the workpiece comes to rest after it has tipped over into its transfer position for further entrainment, in this workpiece position, the fork legs can secure the workpiece against lateral displacement. Appropriate are here the fork legs to form an each

finished is designed. A prerequisite for such a stationary arrangement of the stop is that the height of the workpiece in its delivery position is greater than its height in the overturned state, ie in its transfer position. However, in order to make the device usable for those workpieces that have the same or a greater height in a lying position than in a standing position, a further advantageous embodiment of the invention provides the stop by a preferably flap-shaped, around one to the transport direction to form vertically and parallel to the transport path, horizontal axis pivotable lever, the lower pivot end position defines its stop position. The lower pivoting end position of this lever is advantageously adjustable in order to be able to adapt it to different workpiece heights, and in this context it is also advantageous to also provide the fork arms on the slide appropriately adjustable and fixed, so that their mutual spacing \ certain physical dimensions of corresponding workpieces \ can be customized. In addition, it is expedient to arrange the drive device of the slide and the lever-shaped stop on a common, preferably height-adjustable carrier, the former preferably being provided on its upper side and the latter preferably being provided on its lower side.

The inventive device offers the further significant advantage that they fell, in installing a lagerschalenförnuge workpieces transporting transport device and can be used in particular as an integrable in oinen Wippförderer supply, return purity. In the case of one in such,

to 7 are schematic representations to explain the How the device works.

The device shown in FIGS. 1 to 3 is designed as a feeder integrated into a rocker conveyor known per se, with the aid of which connecting rod bearing caps delivered by the rocker conveyor can be fed to a processing machine in individual cases. In a manner known per se, the rocking conveyor has a horizontal transport beam 10, which is advantageously formed by a cylindrical tube. This performs a recurring, circular movement, as indicated in Fig. 1 by the dash-dotted circle. The side of the Transportbalkcns are support strips 12 _f 14 on which the person seated on the transport bar connecting rod cap are placed in the correct position with its supporting or separating surface. During the downward movement of the transport bar, the connecting rod bearing caps are gradually moved further in a circular arc-shaped movement in the transport direction. At the right-hand end of the transport bar according to FIG. 1, a lifting device designated as a whole with 16 is provided, which has a correspondingly semicircular Plouellagerdeekel receiving piece 18 which is adapted to the cross-sectional shape of the bearing shell recess and which, by means of a transport member 20, moves from a position aligned with the transport bar to a position shown in FIG. 1 can be controlled upward in the feed position in which the support surfaces located to the side of the receiving piece 18 are located
