US 5,771,586 A · Apparatus for skiving belt ends

Abstract

A belt skiving apparatus is provided having a free-standing blade-carrying carriage mounting a pair of rollers defining a nip into which a belt end to be skived is passed. The rollers press together about the belt end to securely grip the belt, with at least one of the rollers being driven, preferably manually, through a crank arm. Rotation of the rollers advances the carriage relative to the belt to advance the carriage across the width of the belt. As the carriage is advanced, the belt is passed through the rollers and through a cutting blade disposed adjacent the rollers, with the blade slicing a thin strip of the upper portion of the belt adjacent its upper face from the remainder of the belt. The rollers may be driven by a ratchet arm to move the carriage along the belt end. Preferably, two pairs of rollers are employed on the carriage, one forward and one rearward of the blade to cut the uncut portion remaining at the trailing side of the belt after the belt passes through the forward roller pair. An adjustable fence can be employed for selective variability of the width of the cut from the belt. A quick-acting cam operated by a lever locks the adjustable fence in various positions for different widths of cuts.

Dependent claims

An apparatus for skiving a conveyor belt having upper and lower faces with a belt thickness therebetween with operation of the skiving apparatus removing a narrow transverse strip having a predetermnined width from the upper face of the conveyor belt at a transverse end portion thereof from a first, leading side of the belt end portion to a second, trailing side of the belt end portion, the apparatus comprising:

a carriage for traveling across the belt end portion in a transverse direction;
a belt cutting blade mounted on said carriage, said belt cutting blade having a forward cutting edge for cutting away the narrow transverse strip from the upper face of the conveyor belt at the belt end portion;
first drive means on the carriage forming a first nip forward of said belt cutting blade to clamp on both faces of the belt at the belt end portion and for driving the carriage in the transverse direction across and along the belt end portion from said leading side of the belt toward said traiing side of the belt end portion, with the belt cutting blade cutting the belt end portion during said driving of the carriage relative to the belt, with the belt end portion passing out of engagement with the first drive means upon the trailing side of the belt end portion passing through said first nip which leaves a small uncut portion of the narrow transverse strip adjacent the trailing side of the belt end portion;
and
second drive means on the carriage forming a second nip rearward of said belt cutting blade for continuing said driving of the carriage in the transverse direction across and along the belt end portion subsequent to said trailing side of the belt end portion passing through said first nip, to drive the forward cutting edge of the cutting blade past said trailing side of the belt end portion to cut said small uncut portion remaining adjacent the trailing side of the belt end portion.

A small free standing apparatus for easy portability to allow the apparatus to be easily moved to a conveyor belt location for skiving a conveyor belt having upper and lower faces with a belt thickness therebetween with operation of the skiving apparatus removing a narrow transverse strip having a predetermined width from the upper face of the conveyor belt adjacent an end portion of the belt to form a transverse groove in the belt end portion, the apparatus comprising:

a carriage for traveling across the belt end portion in a transverse direction;
a carrying handle mounted to the carriage to allow the carriage to be easily lifted and moved from one conveyor belt location to another belt location for operation of the skiving apparatus thereat;
a belt cutting blade mounted on said carriage in a fixed and stationary position thereon during a cutting operation with the blade having a rigid cutting edge for cutting away the narrow transverse strip from the upper face of the conveyor belt at the belt end portion;
a drive on the carriage forming a nip to clamp on both faces of the belt at the belt end portion and for driving the carriage transversely across the belt end portion to force the fixed and stationary cutting blade against the belt end portion with sufficient force to allow the blade rigid cutting edge to cut the transverse strip from the belt end portion thereby skiving the belt;
and
an adjustable guiding surface on the carriage for engaging and guiding an end edge of the end portion of the belt to maintain proper alignment of the belt with respect to the carriage during the skiving operation and being selectively adjustable in a direction for selective variability of the predetermined width of the transverse strip cut from the belt.
