Abstract
Abstract A bypass for production lines for diverting blanks advanced on the line, particularly polygonal blanks of fiber material or a similar light material, past a working unit incorporated in the line. The bypass comprises a diversion path extending in a vertical plane, and at least at the beginning of the diversion path a switch unit is provided for connecting the path with the production line, the switch unit being displaceable in a vertical plane.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
A bypass system for a production line, incorporating a processing unit, for diverting blanks advanced on the line, for example, polygonal blanks of fibre or similar light material, past the processing unit incorporated in the production line, said bypass system comprising a diversion path extending in a vertical plane and including a blank ascending part and a blank descending part, the ascending part comprising a conveyor and the descending part comprising a chute adjustable in a vertical plane, a substantially horizontal band conveyor means for receiving blanks from the uppermost portion of the conveyor of the ascending part, said conveyor means comprising an accumulating unit adapted to accumulate a number of blanks advanced along the bypass, and a switching unit located at the inlet of the conveyor of the ascending part connecting the production line with the diversion path for diverting blanks from the production line to the diversion path, the said switching unit being displaceable in a vertical plane.
Claim 2
Dependent Claim
160 words
A bypass system for a production line, incorporating a processing unit, for diverting blanks advanced on the line, for example, polygonal blanks of fibre or similar light material, past the processing unit incorporated in the production line, said bypass system comprising a diversion path extending in a vertical plane and including a blank ascending part and a blank descending part, the ascending part comprising a conveyor and the descending part comprising a chute adjustable in a vertical plane, a substantially horizontal band conveyor means for receiving blanks from the uppermost portion of the conveyor of the ascending part, said conveyor means comprising an accumulating unit adapted to accumulate a number of blanks advanced along the bypass, and a switching unit located at the inlet of the conveyor of the ascending part connecting the production line with the diversion path for diverting blanks from the production line to the diversion path, the said switching unit being displaceable in a vertical plane.
Claim 3
Dependent Claim
149 words
A bypass system according to claim 1, wherein the accumulating unit comprises a stop for blanks positioned above the forward moving part of the band conveyor means at a point between two revolving rollers thereof, the band conveyor means at least constituting the upper part of the bypass system, the distance from the stop to the forward moving part being smaller than the height of the blank to be conveyed, a pressure member arranged in advance of the stop in the travelling direction of and above the band conveyor means, said pressure member being displaceable from a position where the distance from the lower end of the pressure member to the forward moving part of the band conveyor means is greater than the height of the blank, and at least to a position where the lower end of the member is flush with the lower end of the stop.
Claim 4
Dependent Claim
146 words
A bypass system according to claim 1, wherein the switching unit comprises a band conveyor operating on rollers, the foremost revolving roller in the conveying direction of the conveyor being located in the production line path, the switching conveyor being swingable in a vertical plane about the axis of said foremost roller from a position where the free end of the conveyor is in the production line path to a position where said free end is in the diversion path of the bypass, a band conveyor in the production line path positioned to receive blanks from the free end of the switching conveyor, a revolving drive roller at the free end of the switching conveyor and at the intake end of the production line conveyor, a tensioning roller located below said drive rollers, and a belt drive extending around said drive rollers and said tensioning roller.
