Abstract
A kneading machine includes a kneading machine frame with a lower portion and a head movable relative to the lower portion between a lower operating position and an upper cleaning position. A kneading bowl is on the lower portion and a drivable kneading tool and a lid closing an opening of the kneading bowl in the operating position are the head. The lid is surrounded on a circumferential side by a first safety ring of a safety device which projects beyond the lid on an underside thereof, and which is movably fastened to the lid. The safety device includes a detector to detect a relative movement between the lid and the first safety ring. The kneading machine frame includes at least two trunnion bearings, each defined by a trunnion and a matching receptacle.
Claims15
A kneading machine for food doughs, comprising:
- a kneading machine frame with a lower portion and a head movable relative to the lower portion between a lower operating position and an upper cleaning position;
- a kneading bowl capable of being provided on the lower portion;
- and
- a drivable kneading tool and a lid to close an opening of the kneading bowl in the operating position provided on the head;
- wherein
- the lid is surrounded on a circumferential side by a first safety ring of a safety device which projects beyond the lid on an underside thereof and which is movably fastened to the lid;
- the safety device includes a detector to detect a relative movement between the lid and the first safety ring;
- the kneading machine frame includes at least two trunnion bearings, each of which includes a trunnion and a matching receptacle, one of the trunnion and the matching receptacle is on the lower portion and another of the trunnion and the matching receptacle is on the head such that the trunnion and the matching receptacle engage with each other in the lower operating position and secure a position of the head with respect to the lower portion;
- and
- the first safety ring is provided integrally with a pinch protector of the at least two trunnion bearings.
A method of pivoting a kneading tool into a kneading bowl of a kneading machine for food doughs,
- the kneading machine including a kneading machine frame with a lower portion and a head movable relative to the lower portion between a lower operating position and an upper cleaning position;
- the kneading bowl is capable of being provided on the lower portion and a drivable kneading tool and a lid closing an opening of the kneading bowl in the operating position are provided on the head;
- the lid is circumferentially surrounded by a first safety ring of a safety device which projects beyond the lid on an underside thereof and which is movably secured thereto;
- the safety device includes a detector to detect a relative movement between the lid and the first safety ring and the kneading machine frame includes at least two trunnion bearings, each defined by a trunnion and a matching receptacle;
- one of the trunnion and the matching receptacle is on the lower portion and another of the trunnion and the matching receptacle is on the head such that in the lower operating position the trunnion and the matching receptacle interlock and secure the position of the head with respect to the lower portion;
- and
- the first safety ring is a single structure integral with a pinch protector of the at least two trunnion bearings, each of the trunnion bearings includes a further safety ring which surrounds the trunnion or the matching receptacle fastened to the head on a circumferential side, is fastened movably to trunnion or the matching receptacle and projects downwards, so that an overlap is defined,
- the method comprising:
- a) moving the head relative to the lower portion from the upper cleaning position to the lower operating position;
- b) inserting an obstruction into a still open one of the at least two trunnion bearings;
- c) detecting a relative movement between the safety device and the head;
- and
- d) moving the head in a direction of the upper cleaning position.
