  • Patent number: 10677315
    Abstract: A portable conveyor belt splicing apparatus is provided that includes an upper press assembly and a lower press assembly which include, respectively, upper and lower platen assemblies. The upper and lower press assemblies may each include a forced air cooling system for rapidly cooling platens of the platen assemblies. The upper and lower press assemblies may include insulating assemblies with resilient members that support the upper and lower press assemblies. The resilient members provide structural support and insulate the platens from the frame which reduces the power required to heat the platens. In one form, the apparatus includes a power supply circuit that can alternate between providing power to upper and lower heaters in response to the apparatus being connected to different types of standard power supplies. Further, the power supply circuit permits the use of a single recipe for a particular belt irrespective of the type of power supply.

  • Patent number: 10228043
    Abstract: In one aspect, a vibratory tool is provided for driving a plurality of rivets out from bores of a guide block into an underlying conveyor belt. The tool has a body, a hydraulically operated main drive rod mounted to the body, and a driver aligned with the main drive rod and slidably mounted to the body. The driver has a plurality of elongated drive rod members for engaging and simultaneously driving multiple rivets out of the guide block bores. The driver has an intermediate impact surface for being impacted by the main drive rod impact end as the main drive rod impact end rapidly reciprocates between retracted and extended positions. The driver also has a rearwardly extending spacer wall for axially spacing the driver intermediate impact surface and the main drive rod impact end in the retracted position thereof by at least a predetermined axial distance sized for optimizing energy transfer from the main drive rod to the driver.

  • Patent number: 9884730
    Abstract: A tracking apparatus and method for urging a mistracking conveyor belt towards a correct travel path are disclosed. The apparatus and method utilize downstream shifting of an end portion of an idler roller due to mistracking of the conveyor belt for steering the belt back toward its correct travel path and a reaction force from the belt due to the steering thereof for energizing a tilting action of the idler roller to raise the downstream end portion thereof. The idler roller is mounted to the conveyor structure via a frame assembly including a tilt device mounted internally within the idler roller. The roller is rotatably mounted to an inner tube, and the inner tube member is pivotally mounted to the tilt device, which in combination allow the idler roller to pivot, shift, and tilt to steer a mistracking conveyor belt in relative proportion to degree of mistracking of the belt.

  • Patent number: 9884722
    Abstract: A tracking apparatus and method for urging a mistracking conveyor belt back towards a correct travel path are provided. The apparatus and method both utilize downstream shifting of an end portion of an idler roller due to mistracking of the conveyor belt for directing or steering the belt back toward its correct travel path and a reaction force from the belt due to the steering thereof for energizing a tilting action of the idler roller to raise the downstream end portion thereof. In this manner, the tilting of the idler roller is not mechanically coupled to the downstream shifting of the roller end portion allowing the belt tracking apparatus herein to be bi-directional for use with conveyor belts that may be run in opposite travel directions.
