Abstract
A method for pulling a modular conveyor belt and a belt puller for performing the method. The belt puller has eyelets on one end that interleave with hinge elements on an end of a modular conveyor belt. A rod through the eyelets and the hinge elements connects the belt to the puller, which can then be used to pull the belt. Two ends of an unconnected belt can be pulled together by connecting a belt puller to each end, joining the belt pullers with a ratchet strap or other pulling tool, and tightening the strap to pull the ends together.
Claims18
A belt puller that is attachable to hinge elements of a modular conveyor belt for pulling the modular conveyor belt, the belt puller comprising:
- a puller body including:
- a first side and an opposite second side;
- a first end and an opposite second end extending laterally between the first and second sides;
- a plurality of aligned eyelets spaced apart laterally along the first end and configured to fit into gaps between hinge elements along an open end of a modular conveyor belt;
- a rod having a long segment and a short segment connected by a bend segment maintaining the long segment in non-collinear relation to the short segment;
- wherein the long segment is extendable through the hinge elements and the eyelets fitted into the gaps to attach the belt puller to the modular conveyor belt so that the modular conveyor belt can be pulled by drawing the belt puller in a direction away from the open end of the modular conveyor belt.
A method for pulling an open end of a modular conveyor belt, comprising:
- (a) inserting eyelets along an end of a belt puller into gaps between consecutive hinge elements at an open end of a modular conveyor belt;
- (b) aligning the eyelets with apertures through the hinge elements;
- (c) extending a puller rod through the eyelets and the apertures through the hinge elements;
- (d) drawing the belt puller away from the modular conveyor belt to pull the modular conveyor belt;
- (e) performing steps (a) through (c) with a second belt puller on an opposite open end of the belt across a space between the two open ends;
- (f) attaching a pulling tool between the two belt pullers;
- (g) tightening the pulling tool to pull the two opposite open ends together;
- (h) removing the puller rod from the hinge elements;
- (i) interleaving the hinge elements of the two open ends;
- and
- (i) inserting a hinge rod through the interleaved hinge elements along the two open ends to close the modular conveyor belt.
A belt pulling system that is attachable to hinge elements of a modular conveyor belt separated at opposite ends into two opposite open ends for pulling the opposite open ends of the modular conveyor belt together, the system comprising:
- a pair of belt pullers each including:
- a first side and an opposite second side;
- a first end and an opposite second end extending laterally between the first and second sides;
- a plurality of aligned eyelets disposed and spaced apart along the first end between the first and second sides;
- an attachment point at an opposite second end devoid of eyelets;
- a rod extendable through the eyelets along the first end and through the hinge elements of a modular conveyor belt when the hinge elements are aligned with the eyelets;
- wherein the rod of a first one of the belt pullers is extendable through the eyelets and the aligned hinge elements along or inward of a first one of the opposite open ends and wherein the rod of a second one of the belt pullers is extendable through the eyelets and the aligned hinge elements along or inward of a second one of the opposite open ends;
- a pulling tool attachable between the pair of belt pullers at the attachment points to pull the opposite open ends together.
A method for pulling an open end of a modular conveyor belt, comprising:
- (a) inserting eyelets along an end of a belt puller into gaps between consecutive hinge elements at an open end of a modular conveyor belt;
- (b) aligning the eyelets with apertures through the hinge elements;
- (c) extending a puller rod through the eyelets and the apertures through the hinge elements;
- (d) drawing the belt puller away from the modular conveyor belt to pull the modular conveyor belt;
- (e) before step (a), removing a hinge rod from a hinge joint inward of the open end of the belt;
- and
- (f) lifting the end of a belt module at the hinge joint whose rod has been removed to make its hinge elements at that end accessible;
- (g) then performing steps (c) and (d).
A belt puller that is attachable to hinge elements of a modular conveyor belt for pulling the modular conveyor belt, the belt puller comprising:
- puller body including:
- a first side and an opposite second side;
- a first end and an opposite second end extending laterally between the first and second sides;
- a single opening between the first and second ends and the first and second sides to form a handle;
- a plurality of aligned eyelets spaced apart laterally along the first end and configured to fit into gaps between hinge elements of a modular conveyor belt;
- a rod;
- wherein the rod is extendable through the eyelets and the hinge elements to attach the belt puller to the modular conveyor belt so that the modular conveyor belt can be pulled by drawing the belt puller in a direction away from an open end of the modular conveyor belt.
