Abstract

A device for linking a conveyor belt includes an upper plate and a lower plate. The upper plate includes a highly extendable armature and the lower plate includes an inextensible or quasi inextensible armature. The two plates can be fastened onto the ends of a conveyor belt inserted between the two plates, which as such transforms this conveyor belt into an endless belt.

Abstract

The invention relates to a junction device for a conveyor belt, comprising an upper plate (2) and a lower plate (3). The upper plate (2) comprises a highly expandable frame (7) and the lower plate (3) comprises a non-expandable or almost non-expandable frame (8). The two plates (2, 3) can be attached to the ends of a conveyor belt which are inserted between the two plates, thereby transforming said conveyor belt into an endless belt.

Abstract

A conveyor belt joining staple including upper and lower staple plates situated at different levels joined by knuckles. The upper staple plate has through-holes for passage of staple attaching clip claws and the lower staple plate has bridges that form a recess between a bar of the bridge and an upper surface of the lower plate. The lower staple plate has two shearing lines corresponding to the recess of the bridge, and inlet and outlet toboggans that each have a curved tab. The toboggans are symmetrical with respect to the longitudinal axis of the bridge. Each toboggan has a boss that has an upper round portion and base rounded portions. A portion of the boss is connected to a portion of the tap. Each inlet toboggan-boss is situated in vertical alignment with a corresponding hole of the upper plate for the passage of the clip claws.

Abstract

The proposed device comprises chain links alternately connected to upper fastening plates and to lower fastening plates. These plates comprise fastening claws of which some are arranged on the front and/or rear edges of the plates and others inside the surface of the plates. Stops are provided for blocking the chain links along the edge of the end of a conveyor belt. Another series of similar chain links are placed against the other end of the conveyor belt. The two series of chain links and plates are braced against the upper and lower sides of the respective conveyor belt ends, the claws fastening them to these ends. A connecting rod is then fitted into the chain links of the two pre-interleaved series, bringing together the conveyor belt ends in the process.

Abstract

Tooling intended for fixing hooks connecting the ends of belt conveyors including a fixed lower part forming an anvil linked to a movable upper part by positioning and centering fingers, a main punch, and a complementary punch. The main punch includes a head provided with enlarged parts and can slide in a vertical channel. The complementary punch can slide in a vertical channel. A vertical guiding groove staple is arranged on the side of the complementary punch. A pneumatic hammer provided with a head hammers the main punch which drives the staple in and drives, or hammers, the complementary punch which simultaneously hammers the upper of the hook.

Abstract

A clip for attaching a staple that joins conveyor belt ends that comprises a top portion and a plurality of claws that extend substantially perpendicular from the top portion and are adapted to extend through corresponding holes in the staple. The top portion is formed of a metal sheet, the configuration of which corresponds to that of an accommodation recess provided in a top plate of the staple. The top portion bears at least two claws of the plurality of claws. Each of the claws is connected to the top portion by a bend and each bend includes a re-entrant reinforcing rib embossed therein. Each reinforcing rib is provided in the longitudinal direction of the respective claw approximately in the middle of the width of the respective claw. The claws are formed either by bending the metal sheet at the bends or by attaching the claws to the metal sheet.

Abstract

The invention relates to equipment for fastening conveyor belt joining clips (5) to the ends of a conveyor belt (BT) that includes: a stationary lower portion (3) forming an anvil (31) connected to an upper movable portion (2) by positioning and centering fingers, a main punch (1), and a complementary punch (4). The main punch (1) comprises a head (1') having widened portions (Va) and (1'a). The main punch (1) is slideable into a vertical channel (2'), and the complementary punch (4) is slideable into a vertical channel (2''). A vertical guiding groove (4'') for guiding the clamp (7) is provided on the side of the complementary punch (4). An air hammer having a head (8, 8') strikes the main punch (1) that sinks the clamp (7) and drives the complementary punch (4) by striking thereon, simultaneously striking the upper plate (5') of the clip (5).

Abstract

The proposed device comprises knuckles (CH) alternately connected to upper fastening plates (PS) and to lower fastening plates (PI). These plates comprise fastening claws (7a, 7b) of which some (7a) are arranged on the front and/or rear edges of the plates (PS, PI) and others (7b) inside the surface of the plates. Stops (9) are provided for blocking the knuckles along the edge of the end of a conveyor belt. Another series of similar knuckles (CH) are placed against the other end of the conveyor belt. The two series of knuckles (CH) and plates are braced against the upper and lower sides of the respective conveyor belt ends, the claws (7a, 7b) fastening them to these ends. A connecting rod is then fitted into the knuckles (CH) of the two pre-interleaved series, bringing together the conveyor belt ends in the process.
