Description: |
| Abstract:
A linear pallet stop smoothly decelerates a heavy pallet propelled by a conveyance system in a downstream direction and stops the pallet at a predetermined location. The linear pallet stop comprises a catch arm that is translatable and rotatable between three positions. At the first position, the catch arm first end is in the pallets path to be contacted by the pallet and translated in the downstream direction by the pallet momentum. The downstream translation is resisted by a fluid circuit acting through a cylinder and a slide that is in support contact with the catch arm. A stop surface on the catch arm strikes a fixed surface on the conveyance system at a second position of the catch arm. By retracting the slide with the fluid cylinder when the catch arm is in its second position, the catch arm rotates to a third position whereat its first end is out of the pallets path. The catch arm is guided for translation and location by cam followers that are captured within slots in housings. After the pallet has been propelled further downstream, the cylinder is operated to extend the slide and push the catch arm in the upstream direction and return it to its first position. |
