Description

[0038] The invention will now be elucidated into more detail with reference to the following figures. Herein:

[0039] FIG. 1 shows a part of a device according to the prior art;

[0040] FIG. 2 shows a part of a device according to the invention;

[0041] FIG. 3 shows a side view of a device according to the invention; and

[0042] FIG. 4 shows dough pieces moved according to the invention.

[0043] FIG. 1 shows a part of a device according to the prior art. The device comprises engaging means for a dough piece, comprising an equilateral triangular base plate 2 provided with pins 3 and rotatably mounted on a support 5 about a central point of rotation 4, centrally positioned in the triangular base plate 2. The device according to the prior art can be suspended in a so called carousel, allowing it to move to a position engaging a dough piece, to rotate the dough piece by pushing it with the pins 3, and to move to a position where the dough piece is released again. Such carousel may comprise multiple identical engaging means, positioned behind each other in a length direction and next to each other in a width direction.

[0044] FIG. 2 shows a part 6 of a device according to the invention comprising several engaging means 7, arranged next to each other in the width direction W for gripping dough pieces located in parallel rows extending in the length direction L of a carrier. The engaging means 7 comprise eccentrically placed rotation points 8 for supporting the engaging means 7 with respect to a support 9, for effectively both displacing dough pieces engaged by the engaging means 7 in the length L and width W directions during rotation of the engaging means 7. When placed in a device according to the invention, the support 9 extends in a width direction of the carrier. A device according to the invention may comprise a plurality of these parts 6, each comprising several engaging means 7, arranged one behind the other in the length direction L for gripping successive dough pieces.

[0045] Herein respective subsequent engaging means 7 in the longitudinal direction L may be alternately configured for rotating a piece of dough in a first direction of rotation and moving said piece of dough in a first direction in the width direction, respectively for rotating a next piece of dough in a second direction opposite to the first direction and moving said piece of dough in a second direction opposite to the first side.

[0046] Due to its construction, the device is configured for simultaneously performing the steps of moving the at least one dough piece in the length direction relative to the carrier, moving the at least one dough piece in the width direction relative to the carrier and rotating a dough piece to a predetermined final orientation during movement in the length and/or width direction.

[0047] The engaging means 7 are provided with a (common) mechanical operating member 10, coupled by a rod 11 to transmission members 12 for controlling the movement of the engaging means 7 in the length direction relative to the carrier and for moving the engaging means 7 in the width direction relative to the support carrier and to rotate the engaging means 7 with respect to their support, and therewith a dough piece engaged by the engaging means 7 with respect to the carrier. The device is further provided with a guide 13 (visible in FIG. 3) that is configured for operating the operating member 10 by mechanical contact during movement of the engaging means 7. The operating member 10 is coupled to all engaging means 7 of the part 6.

[0048] FIG. 3 shows a side view 14 of a device according to the invention for spacing dough pieces 15 positioned adjacently in a length L direction on a carrier 16, 17 that extends in a length L and a width W direction, comprising engaging means 7 for a dough piece, said engaging means 7 movable by a drive system formed by a looped chain 18 (which may also be a belt) between a position engaging at least one dough piece (when the engaging means 7 are within region A) and a position releasing the at least one dough piece (when the engaging means 7 are within region B), configured for moving the dough engaging means 7 to the position engaging at least one dough piece 15, moving the at least one dough piece 15 in the length direction L relative to the carrier 16, 17, moving the at least one dough piece 5 in the width direction W relative to the carrier 16, moving the engaging means 7 to the position releasing the at least one dough piece 15, and while doing so, rotating the at least one dough piece to a predetermined final orientation during movement in the length and/or width direction. The device is configured for continuous operation, and so repeating the steps of moving dough pieces 15 in the length L and width W direction and alternately rotating subsequent dough pieces clockwise and counter-clockwise. The carrier 16, 17 comprises a first conveyor 16, configured for transporting the dough pieces in the length L direction, and a second conveyor 17, arranged in length direction L downstream adjacent to the first conveyor 16 and configured for transporting the dough pieces 15 in length direction L during use at a higher speed than the first conveyor 16. The engaging means 7 are coupled to a drive system 18 for moving the engaging means 7 from a starting point S to an end point E in the length direction while in the position engaging a dough piece and subsequently moving the engaging means from the end point back to the starting point while in the position that releases the at least one dough piece and wherein the device is configured for moving and rotating the dough pieces 15 between the starting point S and the end point E. The starting point S is above the first conveyor 16 and the end point E is above the second conveyor 17.

[0049] FIG. 4 shows dough pieces 15 moved according to the invention. The dough pieces are engaged or gripped by engaging means 7 as described above, and then moved or displaced in the length direction L relative to the carrier 16, 17, as well as moved or displaced in the width direction W relative to the carrier 16, 17 and at the same time rotated a quarter turn. This is repeated for each subsequent dough piece 15 positioned adjacently in a length direction on the carrier, wherein subsequent dough pieces are alternately rotated counterclockwise and clockwise and alternately moved in a first direction F in the width direction and in a second direction opposite to the first direction. This way one row 19 of dough pieces 15 is doubled into two lanes 20, 21. In the embodiment shown, this is done for four parallel rows 19, 22, 23, 24 of dough pieces 15.
