  • This turning conveyor 13 possesses a plurality of entrainment members constructed as grippers 14, in the exemplary embodiment there being shown 26 such grippers 14. These grippers 14 are secured at a uniform spacing from one another to an endless revolving transport chain 15 or equivalent structure.
  • the transport chain 15 is guided over two sprocket wheels 16 and 17, the sprocket wheel or gear 17 being driven by any suitable and therefore not particularly illustrated drive in the direction of the indicated arrow '18.

  • the one run of the duplex chain 22 extends directly neighboring the right-hand run of the transport chain 15 of FIG. 1, as best seen by referring to such Figure. This run of the duplex chain 22 is guided in a rail 24.
  • peripheral velocity or speed of the transport chain 15 is in the same sense but somewhat greater than that of the duplex chain 22.
  • the grippers 14 are opened with their mouth openings directed rearwardly with respect to the direction of revolving motion, and such grippers travel in this condition into the path of movement of the fish-scale stream 10 delivered with approximately the same velocity. Since, however, the path of movement of the grippers 14 at this location is curved, and that of the individual product examples 1 1 is linear, the leading edges of the individual products travel into the open grippers 14 whereas the path of movement of such grippers approaches in its direction that of the direction of travel l2'of the fish-scale product stream 10.
  • the sprocket wheels associated with the grippers 14 come out of engagement with the duplex chain 22 and the grippers are returned back into the starting position, for instance through the action "of a suitable restoring or return spring, in other words, are rotated back into the position where the mouth of each such gripper is directed towards the rear, and in which position these grippers now travel back along the lefthand run of the transport chain depicted in FIG. 1.
  • FIG. 2 there is illustrated in the same manner as the illustration of FIG. 1, however, in somewhat simplified form, an exemplary embodiment of apparatus which to a certain extent can be considered to be like the embodiment of FIG. 1 but divided into two mirror-image arranged halves.
  • the twelve grippers 14 are secured to the transport chain 15 in three groups each of which has four such individual grippers, and wherein between each group there is present a space or gap corresponding to the spatial requirements for one such gripper group.

  • the transport chains 15 and 15' possess revolving paths of travel which are mirror-image symmetrical to one another and are rotated with regard to one another such that the gripper groups of one chain fit into the gaps or spaces between two gripper groups of the other chain.
  • duplex chain like the duplex chain of FIG. I and therefore not particularly shown in the illustration of FIG. 2 is associated with each of the transport chains 15 and 15' and each such run moves in the same general direction, indicated by the arrow 12, as the fish-scale stream 10 of the individual products 11.
  • These duplex chains similarly serve the purpose of rotating through 90 the grippers l4 and 14' which pass through the corresponding run of the associated duplex chain, and specifically rotate the grippers 14 in the clockwise direction and the grippers 14' in the counterclockwise direction.
  • the mode of operation of this exemplary embodiment of equipment is basically the same as that considered above with regard to the arrangement of FIG. 1, with the difference that here alternately four grippers of the one chain and four grippers of the other chain are effective.
  • the individual products 11 and 11 which are present at the fish-scale stream 10 in each case have four rotated towards the one side and the successive four such products to the other side.
  • the individual products wherein the originally leading edge or fold have been rotated towards the right as viewed in the direction of conveying have been designated by reference character 11 and those where the fold or edge has been rotated towards the left have been designated by reference character 11.

  • This ball bearing 54 is arranged so as to be axially parallel to the ball bearing 34 and likewise travels at the inside of the hollow rail 30, however somewhat lower than the ball bearing 34.
  • the carriage 31 is guided in the rail 30 in such a manner that it is only displaceable along such rail 30, however cannot be rotated relative to such rail.
  • the shaft 33 is always disposed perpendicular to the lengthwise direction of the rail 30.

  • the axes of these'rollers 64 and 65 are located at right angles to one another. These rollers 64 and 65 serve the purpose of opening the gripper jaws or jaw members 60 and 62, and specifically at such time as they travel upon an associated stationary block or cam, and in FIG. 4 there is shown such block or cam 66 in phantom lines for'the roller 65.
  • this roller 65 serves the purpose of bringing about opening movement of the associated gripper upon travelling onto the block or cam 66 when the gripper jaw members 60 and 62 are in the position depicted in FIGS. 3 and 4.

  • this spring 73 is to rotate the shaft member 33 and the sprocket wheel 58 associated therewith to such an extent that the end of the slot 69 impacts against'the contact or impact pin 70, that is to say, serves to hold the gripper jaw members 60 and 62 in a position where they are directed towards the rear.
  • FIGS. 3 and 4 there is also illustrated the duplex chain 22 which was discussed in conjunction with the embodiments of FIGS. 1 and 2, and wherein the lower row of link elements are guided in a substantially U- shaped rail 24 lined with a sliding layer or coating 74.

  • the jaws 60 and 62 are automatically rotated about the axis of the shaft member 33.
  • the speed of rotation and therefore also the path through which the gripper 14 moves during a certain rotation, for instance through an angle of 90 is dependent upon the difference of the revolving speed of movement of the transport chain 15 and the duplex chain as well as-the diameter of the sprocket wheel 58.
  • the gripper construction described in conjunction with FIGS. 3 and 4 can not only be employed for the arrangements of turning apparatus depicted in conjunction with FIGS. 1 and 2 but also for similar constructional embodiments in which the gripper jaws or jaw members 60 and 62 so to speak depend from the rail 30. Moreover, the illustrated gripper construction can also be employed for embodiments in a conventional fish-scale stream of turning conveyors in which the trailing edge, that is to say the lower edge of the individual products, is engaged.
  • FIG. 5 Such type of embodiment has been schematically depicted in FIG. 5.
  • the grippers 14 are secured at a uniform spacing at the transport chain 15 and are each equipped with a respective sprocket wheel or gear 58 which in conjunction with the chain member, not here particularly illustrated, and which can move slower or quicker, brings about the rotation of the gripper jaw members or jaws 60 and 62.
  • the transport chain 15 is driven with the speed of rotation V which is somewhat greater than the velocity or speed of movement V, of an infeed conveyor band arranged above the grippers l4 and which delivers thereto the fish-scale formation. Since the grippers 14 are moved quicker than the delivery or infeed speed of the fish-scale formation 10, the gripper jaws 60 and 62 which are opened by means of the associated block or cam overtake each individual product of the fish-scale stream and engage such at its trailing edge.
