Bakery flexible belt carrying plate

Claim 1

A device for automatically conveying and transferring at a transfer position semi-manufactured dough products such as bread and doughnuts to a subsequent process stage such as a fryer or a band oven, comprising a carrying plate assembly having a core plate, support means supporting said core plate, an endless flexible belt made of material provided with evenly distributed laterally extending ridges on its exterior surface in contact with said dough products positioned around said core plate, a roller having projections around it, means for brinGing the roller into or out of meshing relationship with the lower exterior surface of the belt at the transfer position where the dough products are transferred, and means for rotating the roller in the backward direction relative to the direction in which the dough products are to be transferred so as to rotate the belt around the core plate for transferring the dough products, comprising further a swingable conveyor for conveying said carrying plate assembly to said transfer station for transferring said dough products, said conveyor having a belt wound around two rollers positioned at the foremost and rearmost ends thereof, swingable around said foremost roller between a horizontal position and an inclined position, with said rearmost roller at a level below said foremost roller and coming into contact with driving means, which is adapted to reverse the direction of rotation of said conveyor belt.

Claim 2

A device for automatically conveying and transferring at a transfer position semi-manufactured dough products such as bread and doughnuts to a subsequent process stage such as a fryer or a band oven, comprising a carrying plate assembly having a core plate, support means supporting said core plate, an endless flexible belt made of material provided with evenly distributed laterally extending ridges on its exterior surface in contact with said dough products positioned around said core plate, a roller having projections around it, means for brinGing the roller into or out of meshing relationship with the lower exterior surface of the belt at the transfer position where the dough products are transferred, and means for rotating the roller in the backward direction relative to the direction in which the dough products are to be transferred so as to rotate the belt around the core plate for transferring the dough products, comprising further a swingable conveyor for conveying said carrying plate assembly to said transfer station for transferring said dough products, said conveyor having a belt wound around two rollers positioned at the foremost and rearmost ends thereof, swingable around said foremost roller between a horizontal position and an inclined position, with said rearmost roller at a level below said foremost roller and coming into contact with driving means, which is adapted to reverse the direction of rotation of said conveyor belt.

Claim 6

A device for automatically transferring semi-manufactured dough products such as bread and doughnuts to a subsequent processing stage at a transfer position such as a fryer or a band oven, comprising: a carrying plate assembly having an endless flexible belt rotatable around a core plate, means to support said core plate; a first conveyor for the forwarding of the carrying plate assembly when carrying dough products; a second conveyor having a foremost and a rearmost roller and being for the discharge of the dough products located at the transfer position on the extension of the first conveyor and swingable around its foremost roller and having around it a belt arranged to reverse the direction of rotation upon the completion of the swinging motion; a third conveyor for the return of the carrying plate assembly portioned underneath the first and the second conveyor, a first and a second approach switch each positioned at said transfer position; a core plate belt roller and a reciprocal shaft supporting said core plate belt roller, an electromagnet arranged to move said shaft reciprocally and being activated by the first approach switch when the carrying plate assembly approaches the transfer position so as to elevate the roller for engaging the belt; and an arm with its upper end connected to a joint fixed relative to the second conveyor and with its lower portion being slidable in a geared motor electrically connected to the first and the second approach switches, a first and a second time switch each connected to said motor, said arm being arranged to retract after a predetermined length of time from the time the carrying plate assembly approaches the transfer position by the coaction of the first approach switch, the first time switch and the gEared motor, and to extend after a predetermined length of time by the coaction of the second approach switch, the second time switch and the geared motor.

Claim 7

A device for automatically transferring semi-manufactured dough products such as bread and doughnuts to a subsequent processing stage at a transfer position such as a fryer or a band oven, comprising: a carrying plate assembly having an endless flexible belt rotatable around a core plate, means to support said core plate; a first conveyor for the forwarding of the carrying plate assembly when carrying dough products; a second conveyor having a foremost and a rearmost roller and being for the discharge of the dough products located at the transfer position on the extension of the first conveyor and swingable around its foremost roller and having around it a belt arranged to reverse the direction of rotation upon the completion of the swinging motion; a third conveyor for the return of the carrying plate assembly portioned underneath the first and the second conveyor, a first and a second approach switch each positioned at said transfer position; a core plate belt roller and a reciprocal shaft supporting said core plate belt roller, an electromagnet arranged to move said shaft reciprocally and being activated by the first approach switch when the carrying plate assembly approaches the transfer position so as to elevate the roller for engaging the belt; and an arm with its upper end connected to a joint fixed relative to the second conveyor and with its lower portion being slidable in a geared motor electrically connected to the first and the second approach switches, a first and a second time switch each connected to said motor, said arm being arranged to retract after a predetermined length of time from the time the carrying plate assembly approaches the transfer position by the coaction of the first approach switch, the first time switch and the gEared motor, and to extend after a predetermined length of time by the coaction of the second approach switch, the second time switch and the geared motor.
