Definitions

  • the invention relates generally to conveyor belts. More particularly, the invention relates to belting mechanical splice.
  • One common configuration of the mechanical splice is an elongated metal plate through which a plurality of fasteners are extended.
  • the elongated metal plate reduces the potential of the fasteners tearing through the ends of the conveyor belt when the conveyor is used.
  • a drawback of the metal plate mechanical splice is that it can reduce the flexibility of the conveyor belt such as when the conveyor belt passes around the rollers at the end of the conveyor.
  • An embodiment of the invention is directed to a mechanical splice for belting that is fabricated from belting material.
  • FIG. 1 is an end view of a conveyor belt having a mechanical splice.
  • FIG. 2 is an enlarged view of the mechanical splice
  • FIG. 3 is another view of the mechanical splice where the mechanical splice has a curved configuration.
  • Fig. 4 is a first side view of the mechanical splice proximate an edge of the conveyor belt.
  • Fig. 5 is a second side view of the mechanical splice proximate the end of the conveyor belt.
  • Fig. 6 is an end view of the mechanical splice at the end of the conveyor belt.
  • the invention relates to a mechanical splice 20 used to connect ends of a conveyor belt 10 as illustrated in Figs 1-6.
  • the mechanical splice 20 utilized in this invention is fabricated from a non-metallic material.
  • the material of the mechanical splice 20 is similar to or identical to material that is used in the conveyor belt 10.
  • the conveyor belt 10 includes opposite ends 30 that are turned upwardly as illustrated in Figs. 2-6. In certain embodiments, the conveyor belts ends 30 are oriented generally perpendicular to the other portions of the conveyor belt 10.
  • the width of the conveyor belt end 30 that is turned upwardly is at least as wide as the flexible clamping connector 60 that is intended to be used with the conveyor belt 10. In other embodiments, the width of the upwardly turn conveyor belt end 30 is approximately equal to the width of the flexible clamping connector 60.
  • each of the conveyor belt ends 30 has a plurality of apertures formed therein through which fastening devices are extended when attaching the conveyor belt ends 30 to each other.
  • the fastening devices include a screw 40 and a nut 50 that is detachably engagable to the screw 40.
  • the number and size of the fastening devices is determined by factors such as the anticipated load to which the conveyor belt 10 will experience during the operation of the conveyor.
  • the flexible clamping connector 60 is fabricated from a piece of material that is similar to the material used in the conveyor belt 10. In other embodiments, the flexible clamping connector 60 is fabricated from the same material as the material used to fabricate the conveyor belt 10.
  • the flexible clamping connector 60 can be fabricated from material that is thicker or thinner than the thickness of the material used in the conveyor belt 10.
  • the flexible clamping connector 60 may be fabricated by folding over the end of the conveyor belt 10 proximate the conveyor belt end 30 so that the flexible clamping connector 60 is positioned against the conveyor plate end 30. In this configuration, the flexible clamping connector 60 is attached to the other portions of the conveyor belt 10.
  • a benefit of the mechanical splice 20 of this invention is that the tension on the mechanical splice 20 is substantially equal across the width of the conveyor belt 10. Using such a configuration reduces stresses on the conveyor belt 10 and/or the mechanical splice 20 caused by the force not being substantially equal across the width of the conveyor belt 10 as such locally elevated stresses may lead to premature degradation of the conveyor belt 10.
  • Figs. 1 and 2 illustrate that the mechanical splice 20 has a generally linear configuration even if the mechanical splice 20 is oriented at an angle other than 90 degrees with respect to the edge of the conveyor belt 10, it is possible for the mechanical splice 20 of this invention to have other non-linear configurations.
  • An example of one such alternative configuration is a V-shape.
  • a significant benefit of the mechanical splice 20 of this invention is that the mechanical splice 20 may be oriented in an angled configuration as illustrated in Fig. 1 such that when the mechanical splice 20 is over the roller (which while not illustrated in Fig. 1 is located along the edge of the conveyor) at the end of the conveyor, the mechanical splice 20 does not open where the conveyor belts ends 30 are pulled apart from each other.
  • Fig. 3 illustrates the mechanical splice 20 being curved such that the center of the mechanical splice 20 is lower than opposite end of the mechanical splice 20. This type of curvature happens when the mechanical splice 20 is passing over the roller at the end of the conveyor.
  • angle configuration means that an angle between the mechanical splice 20 and an edge of the conveyor belt 10 is not 90 degrees. In certain embodiments, the angle is between about 40 degrees and about 80 degrees.
  • An advantage of the invention as compared to conveyors utilizing metal mechanical splices is that the mechanical splice 20 of this invention reduces noise emitted from the conveyer while the conveyor is being used.
  • Another advantage of the invention as compared to conveyors utilizing metal mechanical splices is that the weight of the mechanical splice 20 is reduced as compared to mechanical splices with metal connector plates and this reduces the centrifugal force that occurs as the splice moves around the roller.
  • the invention is adapted for use on conveyors used in a variety of applications.
  • One field in which the invention is particularly suited is conveyors used in the agricultural field such a drapers.
  • the techniques described herein relate to a conveyor belt (10) including: a first belt end (30) of the conveyor belt having an upper side and a lower side; a second belt end (30) of the conveyor belt having an upper side and a lower side; and a flexible clamping connector (60) attached to the lower side of the first belt end and the lower side of the second belt end and configured to attach the first belt end (30) to the second belt end and form a splice (20), the flexible clamping connector (60) is nonmetallic.
  • the techniques described herein relate to a conveyor belt (10), the flexible clamping connector (60) using a plurality of fasteners.
  • the techniques described herein relate to a conveyor belt (10), the flexible clamping connector (60) including a plurality of segments positioned at the first belt end (30) and the second belt end (30).
  • the techniques described herein relate to a conveyor belt (10) , the flexible clamping connector (60) having a first side at the first belt end (30) and a second side at the second belt end (30).
  • the techniques described herein relate to a conveyor belt (10), the flexible clamping connector (60) included of the same flexible material as the conveyor belt (10). [0036] In some aspects, the techniques described herein relate to a conveyor belt (10), the flexible clamping connector (60) is thinner than the conveyor belt.
  • the techniques described herein relate to a conveyor belt (10), the flexible clamping connector (60) extends across an entire width of the belt (10).
  • the techniques described herein relate to a conveyor belt (10), the flexible clamping connector extends across only a portion of the width of the belt (10). [0039] In some aspects, the techniques described herein relate to a conveyor belt (10), the first belt end including a turned up portion.
  • the techniques described herein relate to a conveyor belt (10), the first belt end and the second belt end including a plurality of apertures for a plurality of fasteners. [0041] In some aspects, the techniques described herein relate to a conveyor belt (10), the splice (20) formed at an angle of 90 degrees with respect to an edge of the conveyor belt.
  • the techniques described herein relate to a conveyor belt (10), the splice formed having a V-shape.
  • the techniques described herein relate to a conveyor belt (10), wherein a center of the splice is lower than an opposite end of the splice.
  • the techniques described herein relate to a conveyor belt (10), the splice formed at an angle between 40 and 80 degrees with respect to an edge of the belt.
