DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for feeding pieces of dough, which have for instance been made on a cambering machine, to dough trays of a pre-proofing cabinet.
A suchlike device that is used to practice comprises a first conveyor which conveys the pieces of dough from the cambering machine to a second conveyor. The second conveyor can be driven intermittently or can have a sinusoid conveying velocity. Pieces of dough on the second conveyor are pushed off this by a pusher mechanism in a direction transverse to the conveying direction of the second conveyor into dough trays which are placed along the second conveyor. The pieces of dough are pushed off the second conveyor when the conveying velocity of the second conveyor is at its lowest. With the help of a suchlike device approximately 6000 pieces of dough per hour can be placed in dough trays, without extensive and expensive additions.
An object of the present invention is to provide a device for feeding pieces of dough to dough trays of a pre-proofing cabinet, with the help of which 8000 pieces of dough can in a simple manner be fed to dough trays per hour, the device remaining compact and cheap.
For this purpose the invention provides a device for feeding pieces of dough to dough trays of a pre-proofing cabinet, which device is provided with a first conveyor belt for continuously conveying pieces of dough in a conveying direction and at a conveying velocity, which first conveying belt has a dough bearing surface, and an opposing driving surface, an incoming end and an outgoing end, which first conveyor belt contains at least four driving rolls, in which a first of the driving rolls defines the incoming end and a second of the driving rolls defines the outgoing end, the first and the second driving roll contacting the driving surface of the first conveyor belt and lying in one plane, in which a third of the driving rolls lies under the plane and between the first and second driving rolls and contacts the dough bearing surface of the first conveyor belt, in which a fourth of the driving rolls lies beneath the third driving roll and contacts the driving surface of the first conveyor belt, the third driving roll being located between the first and the fourth driving roll, a first driving means for driving at least one of the driving rolls of the first conveyor belt, a second conveyor belt for continuously conveying pieces of dough in a conveying direction and at a conveying velocity, which second conveyor belt is placed on the extension of the first conveyor belt, which second conveyor belt has a dough bearing surface and an opposing driving surface, an incoming end and an outgoing end, which second conveying belt contains at least four driving rolls, in which a first of the driving rolls defines the incoming end and a second of the driving rolls defines the outgoing end, the first and the second driving roll contacting the driving surface of the second conveyor belt and are in one plane, in which a third of the driving rolls lies under the plane and between the first and second driving rolls and contacts the dough bearing surface of the second conveyor belt, in which a fourth of the driving rolls lies beneath the third driving roll and contacts the driving surface of the second conveyor belt, the third driving roll being located between the second and the fourth driving roll, in which the incoming end of the second conveying belt connects to the outgoing end of the first conveyor belt, a second driving means for driving at least one of the driving rolls of the second conveyor belt independant of the drive of the first conveyor belt, a trolley moving reciprocally in conveying direction from a starting position to a farthest position, on which trolley the second and the third driving roll of the first conveyor belt and the first and third driving roll of the second conveyor belt are mounted, a third driving means for driving the trolley independant of the drive of the conveyor belts, the second driving means being a driving means for increasing the
