Patent number: 7287641Abstract: The invention relates to a drive device for intermittent driving of a conveyor that partly surrounds a drum rotatable around a centre axis. The drive device includes drive member and motion transmission member. According to the invention, the drive member is arranged to execute a reciprocating motion. The motion transmission member, in the motion of the drive member in a first direction, is arranged to impart the drum a rotary motion in a first rotary direction and impart the conveyor a motion. Further, the motion transmission member, in the motion of the drive member in a second direction, is arranged to impart the drum a rotary motion in a second rotary direction in such a way that the conveyor is at rest. The invention also relates to a corresponding method.Type: GrantFiled: October 14, 2004Date of Patent: October 30, 2007Inventor: Tommy Lindvall

Patent number: 7051680Abstract: The invention relates to an animal keeping device comprising a floor (1), a tending device and a drive means (4) for the tending device. The tending device may be intended for cleaning or feeding. The purpose of the invention is to automate this work in a cost-effective manner. In accordance with the invention the floor (1) is vertically movable for the absorption of energy and is provided with energy-absorbing means (5) arranged to take up energy generated when an animal (2), due to its movement, subjects the floor to dynamic loading (F). The dynamic loading effects vetical movement of the floor (1). The energy-absorbing means (5) is arranged to provide the drive means (4) with energy. The invention also relates to a method for animal keeping wherein tending is performed using the device claimed.Type: GrantFiled: March 11, 2002Date of Patent: May 30, 2006Inventor: Tommy Lindvall

Patent number: 6851390Abstract: A livestock pen with ends and long sides for permanently restricting the freedom of movement of animals kept therein. The livestock pen contains a moving, endless belt that supports all the weight of the animals. The belt is arranged to move from an inlet end towards an outlet end. An outlet end panel forms a gap between the belt and the outlet end panel's lowermost transverse member. At the belt's outlet end, a sensing means, when actuated, stops any ongoing belt movement. An additional aspect relates to a method for stopping the movement of an endless belt in a livestock pen, whereby a sensing means registers when a part of an animal is in a restricted area of the livestock pen. A signal from the sensing means then stops the belt's drive mechanism.Type: GrantFiled: November 26, 2001Date of Patent: February 8, 2005Inventor: Tommy Lindvall
