Conveyor belt splicing system and method
View Patent ↗A system of splicing ends of conveyor belts is provided that enables a splice installer to install splices in an easy and fast manner. In one aspect, the system includes a base having a recess extending therealong configured to fit fastener members of conveyor belt fasteners therein so that the fastener members do not shift as the belt fasteners are attached to the belt ends. In another aspect, removable rivet guide blocks are provided which significantly reduces the weight of an alignment bar having upper plate members of the belt fasteners secured thereto. In addition, the removable guide blocks allow the installer to secure the upper plate members to the alignment bar without having to deal with the heavy weight of multiple guide blocks fixed thereto. A method of splicing belt ends is also provided which includes indexing the removable guide block along the alignment bar during for riveting operations.
1. A system for splicing conveyor belt ends together, the system comprising:
conveyor belt fasteners having fastener members including scalloped end edges with alternating projections and recesses;
an applicator tool for securing conveyor belt ends together;
a base of the applicator tool;
an upwardly facing, elongate recess extending lengthwise along the base sized to fit the belt fastener members therein; and
locating projections extending into the elongate recess on either side thereof configured to be fit into the edge recesses and between the edge projections of the belt fastener members for keeping the fastener members substantially stationary as the belt fasteners are secured to the belt ends, wherein the conveyor belt fasteners include upper plates and lower plates with the lower plates being the belt fastener members having the scalloped end edges and snugly fitting in the elongate recess, and
an elongate alignment bar to which the upper plates are secured for being mounted to the base to position the upper plates in alignment over the lower plates in the elongate recess with the belt ends therebetween.
2. A system for splicing conveyor belt ends together, the system comprising:
conveyor belt fasteners having fastener members including scalloped end edges with alternating projections and recesses;
an applicator tool for securing conveyor belt ends together;
a base of the applicator tool; an upwardly facing, elongate recess extending lengthwise along the base sized to fit the belt fastener members therein; and
locating projections extending into the elongate recess on either side thereof configured to be fit into the edge recesses and between the edge projections of the belt fastener members for keeping the fastener members substantially stationary as the belt fasteners are secured to the belt ends, wherein the elongate recess has substantially vertical side walls on either side thereof with the locating projections formed on the side walls to extend into the elongate recess generally transverse to the lengthwise extent thereof, and the elongate recess includes a bottom anvil surface and the recess including the bottom anvil surface is formed integrally with a separate stepped anvil plate including the substantially vertical side walls and the locating projections formed thereon.
3. A system for splicing conveyor belt ends together, the system comprising:
conveyor belt fasteners having fastener members including scalloped end edges with alternating projections and recesses;
an applicator tool for securing conveyor belt ends together;
a base of the applicator tool;
an upwardly facing, elongate recess extending lengthwise along the base sized to fit the belt fastener members therein; and
locating projections extending into the elongate recess on either side thereof configured to be fit into the edge recesses and between the edge projections of the belt fastener members for keeping the fastener members substantially stationary as the belt fasteners are secured to the belt ends, wherein the elongate recess includes a bottom anvil surface having rivet head forming cups thereon aligned with rivet receiving apertures of the belt fasteners.
4. The system of claim 3 wherein the bottom anvil surface is formed on a separate anvil plate that is secured in the elongate recess, and edge recesses on either side edge of the anvil plate configured to receive the locating projections therein.
5. A system for splicing conveyor belt ends together, the system comprising:
conveyor belt fasteners having fastener members including scalloped end edges with alternating projections and recesses;
an applicator tool for securing conveyor belt ends together;
a base of the applicator tool;
an upwardly facing, elongate recess extending lengthwise along the base sized to fit the belt fastener members therein; and
locating projections extending into the elongate recess on either side thereof configured to be fit into the edge recesses and between the edge projections of the belt fastener members for keeping the fastener members substantially stationary as the belt fasteners are secured to the belt ends, wherein the base includes raised guide surfaces adjacent either side of the elongate recess to allow the belt ends to slide on the guide surfaces and over the belt fastener members without interference from the belt fastener members in the elongate recess.
6. The system of claim 5 including an elongate alignment bar having alignment posts spaced therealong, and a guide block for guiding rivets driven through apertures of the fastener plates and the belt ends and having locating bores with the posts sized to be in clearance with the bores to allow the guide block to be easily placed on the posts and removed therefrom for repositioning of the block along the bar to rivet all of the belt fasteners to the belt ends using the same guide block.
7. The system of claim 5 wherein the elongate recess has substantially vertical side walls on either side thereof with the locating projections formed on the side walls to extend into the elongate recess generally transverse to the lengthwise extent thereof.
8. The system of claim 7 wherein the elongate recess, the vertical side walls and the locating projections are integrally formed with the base.
