Definitions
- the present invention relates to a conveyor belt connection.
- the invention relates to joining by junction of conveyor belts by sewing along particular trajectories forming a seam field.
- Conveyor belts are industrial-scale treadmills. They consist of one or more textile sheets whose function is to transmit the force, and of a rubber coating whose function is to protect the textile plies from wear and shocks.
- the belt sections are manufactured in rolls weighing up to 10 tonnes. These rolls have a length of 200m on average. The strip sections are then assembled on the carrier assembly site to form a strip up to several tens of kilometers. This results in a large number of junctions.
- junctions of the state of the art are made by vulcanization (hot junction), with patches (mechanical junction) or by bonding (cold junction). These junctions require time to be performed. In the case of rupture of the junction during operation of the latter, considerable losses are caused by stopping the conveyance.
- the assembly is a real problem, especially as it weakens the band. In fact, a 75% resistance to the tensile strength of the web is obtained in the best case with a strength of 50% of the tensile strength of the web in many cases, the joint is the weak point of the conveyor belt.
- the stapling is to perforate the ends of strips, then assemble said strips by very strong metal elements staples that connect the holes of the two strips. Unlike gluing, this process allows small areas for joining. But the passage holes of the staples weaken the band (the document DE.41 18 946 A1 has holes of bands adapted to the stapling where are used uses threads instead of staples for joining by bonding) Finally, the plaintiff found that the seam join has better results. It is a mechanical junction by wire over a long area (see document JP 2002 372106 A)
- the present invention is in the field of seam junctions.
- the present invention aims to solve this technical problem with a solution that damages the carcass as little as possible.
- the aim of the invention is to meet these needs, and to solve at least some of the problems posed by the state of the art, in particular to obtain a universal band junction adapted to all types of conveyor belt carcasses.
- the plaintiff connects the male carcass to the female carcass throughout the thickness with a distribution of efforts by the following steps:
- This document aims to join an aramid band. It is a very thin band with a layer of tissue without matrix.
- the invention distributes the forces by a surface seam and a coating on the teeth.
- the teeth of JP 2002 372106 A have a different function. They serve to avoid the hinge effect and not to distribute the efforts. They are not combined with a coating.
- this known document does not aim at a universal junction; but is limited to only one particular type of tape. It does not seek a distribution of forces by a coverage of the band junction but an end join.
- the holes are placed in accordance with a staple connection structure.
- the teeth of the teeth do not have the geometry of the invention, the wires are not the wires of high toughness of the invention, this without the way to cover the angles of the junction of the invention.
- the invention meets the need to improve these junctions, improving their strength and strength.
- the invention aims to meet these needs, and to solve at least some of the problems posed by the state of the art; in particular to obtain a universal band junction adapted to all types of conveyor belt carcasses.
- Both ends of the conveyor belt comprise at least one carcass, and a coating, by stitching.
- the assembly process comprises the following steps:
- This method is particular in that the seam is made according to a predetermined sewing field according to the type of conveyor belt.
- the conveyor belts are formed of a fold or several folds.
- the fold (or assembly of folds) is referred to as the carcass.
- the strips formed in a single fold, called monoplies, are assembled by cutting the two ends in the form of complementary teeth.
- the seam serves to secure all the material thus obtained.
- multiplies The strips formed of several folds called multiplies are assembled with an alternative solution. It consists of the two ends of the band to be assembled to cut the plies individually, in a staggered position at each fold, to obtain a kind of staircase, complementary on one end with respect to the other, which also gives interpenetration of the carcasses. The seam will mechanically secure the entire junction obtained.
- This method is particular in that the mechanical assembly is obtained in a uniform manner thanks to the sewing field. Indeed, the seam in the form of vertical suture or zigzag does not allow to have a satisfactory assembly. The high density of sewing threads and perforations in the material will result in low efficiency of the assembly.
- the solution of the seam field according to the invention allows a transmission of forces from one end to the other in a homogeneous manner.
- the teeth and the floors are used to obtain a good dynamic behavior, knowing that the assembly with stretches or diagonals can be carried out through a reinforcement woven or not, stitched at both ends; but the dynamic behavior of this junction is less efficient.
- the conveyor belt is composed of at least the carcass, an interstice and the coating.
- an additional step of laying by reinforcing seams in woven or nonwoven is provided between the steps of removing the coatings and seam for assembling the carcasses.
- said teeth have a length ranging from 10 mm to 5000 mm depending on the thickness and the width of the conveyor belt to be joined, preferably of the order of 200 mm.
- the outfit improves if the length is increased,
- said stages have a length defined according to the type of band, the number of folds, the width and the thickness of the band, ranging from 1mm to 5000mm, preferably of the order of 50mm, the holding improving if the length is increased.
- said seam has a seam density of 1 thread / cm to 100 thread / cm, depending on the thickness, width and type of the conveyor belt to be junction preferably of the order of 15 to 20 threads / cm .
- the yarn material is a typically liquid crystal polymer. Indeed, this material has a good compromise between specific strength, breaking strain, heat resistance and knot strength.
- the coefficient of friction of the wire is important.
- the angle complementary to the angle of the threads of the seam with respect to the longitudinal axis of the strip is between 0 to 90 °, preferably of the order of 45 °.
- the complementary angle is the complement at 90 °.
- the angle of the seam with respect to the longitudinal axis of the strip is 60 °.
- the length of the stitching point has a length ranging from 1 to 200 mm, preferably from 3 to 20 mm.
- the angle of the teeth relative to the longitudinal axis of the strip is between 0 ° and 90 °, preferably defined as a function of the width and the thickness of the conveyor belt to be joined, preferably of the order of 7 °.
- the goal is to get a larger number of teeth than larger angles, while maintaining sufficient strength.
- the present invention also relates to the use of a sewing method according to those described above to obtain an assembly of two conveyor belt ends consisting of a carcass and a coating.
- the invention also relates to a conveyor belt comprising a carcass and a coating.
- the conveyor belt is formed of ends comprising at least one carcass and a coating, said ends being assembled by a seaming field of defined density, in symmetrical or asymmetrical cut, that is to say with offset teeth.

- ç the width of the junction which is the same as that of the band to be joined.
- g the stitch length that influences the sewing efficiency.
- h the sewing density expressed in number of threads / cm.
- the sewing is performed according to determined trajectories and characterized by the angle between the seam trajectory and the longitudinal axis of the strip.
- the sewing field formed by a large number of sewing passages, defined by the sewing density, must be longer than the teeth and as wide as the band to be joined.
- the possible tooth profiles according to the invention shown in Figures 3, 4 and 5 have ends 7 and 8 are cut in asymmetrical profiles with respect to the median plane of the strip.
- the ends 9 and 10 are cut in profiles symmetrical with respect to the median plane of the strip.
- the tips 1 1 and 12 are cut with non-homogeneous angles on both sides of the teeth.
- Cutting teeth can be done with a cutter, a rotary cutter, a shear or any other cutting object, electrical or not.
- Figure 6 shows two junction ends of a monopli conveyor belt whose pins 13 and 14 respectively represent the carcass monopli and its rubber coating.

- the second step shown in Figure 7 is to remove the coating. This step can be performed using a cutter by removing strips of coating or by sanding the coating with a sanding disc for example.
- the length of uncovered liner should be longer than the length of the teeth.
- the third step is to cut the teeth according to the chosen profile.
- the different profiles shown in FIGS. 3 to 5 can be used without the list of possible profiles being fixed; the essential according to the invention is to have decreases of slow section at the teeth to ensure a gradual transfer of the tensile force from one end of the tape to the other.
- the cutting can be performed using a cutter or any other cutting object, electric or not.
- the fourth step shown in FIG. 9 consists of sewing the assembled teeth along defined trajectories shown in FIG.
- the objective is to obtain the filled sewing field in a homogeneous way in order to distribute the tensile stresses. Sewing can be performed using so-called heavy sewing machine, for example the 204 of the so-called Durkopp-Adler brand. This type of machine is suitable for thicknesses up to 14 mm material.
- the fifth step is to cover the seam with a piece of coating 15.
- This step can be performed by gluing or vulcanization for example. This step will help protect the sewing threads including wear caused by the material transported by the conveyor belt.
- the piece of conveyor belt called plywood 17 shown in FIG. 11 comprises carcass plies 18, interplies 19 made of rubber material for example and rubber coating 20 for example.
