ES246330U - A transportable automatic weighing packer (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

1.a transportable automatic weigher-weigher, characterized by being constituted by a frame of welded metal profiles, which will support the main and auxiliary conveyor belts, parallel to each other, driven by separate electric geared motor units located on an upper external support, having both belts in its free lower pulleys a tensioning device, on channels formed in the frame itself, both ribbed profile ribbons and with side walls, especially for the dragging and lifting of materials. 2.the bottling-weigher itself, according to the previous claim, characterized in that in the lower part of the frame and on the head of the tapes, the receiving hopper of material is placed, provided with a grid of rods and tubes of rigid and soft material and interchangeable, which will serve as a buffer in the pouring of the material inside the aforementioned receiver hopper. 3. The bottling-weigher itself, according to the preceding claims, characterized in that in the front of the frame is located the weighing hopper, of square shape and stably coupled to a scale, which hopper receives the materials transported by the lifting belts, provided of an automatic opening unloading door and with a lower packaging hopper, on which it opens, this latter hopper having its lower base suitable for the easy coupling of the container to be filled. 4. The bottling-weigher itself, according to the preceding claims, characterized in that the weighing hopper has in its interior a rubber skirt, interchangeable, which will serve as a buffer to the fall of the materials discharged by the lifting belts. 5. The bottling-weigher itself, according to the preceding claims, characterized by having a mechanism for automatic opening of the discharge door, consisting of a double lever located on both sides of the hopper, on a horisontal shaft horizontally a pusher latch, fixed to the axis of an electromagnet, so that when the electromagnet is activated the latch will be raised by pushing the double lever and releasing the door that will open by the weight of the materials located in the hopper, which will be emptied, closing again by the action of a counterweight located on a support fixed to the axis of the discharge door itself. 6. The own weigher-packing machine, according to the preceding claims, characterized in that it has micro-switches located on the scale, which are activated when a certain weight is reached in the weighing hopper, by actuating one of the microswitches to the gearmotor of the main belt, just when reaching a weight close to the quantity to be packed, weight completed by the material poured by the auxiliary tape that continues to work until the total weight causes the scale to activate another microswitch that stops the second belt and activates the electromagnet of the opening of the hopper door. 7. The weigher-filler itself, according to the previous claims, characterized by having as a variant a pedal device for opening the unloading door, mechanically, consisting of a hook lever and counterweight at its rear end, which will descend to the the pedal is activated and the door that will open by the push of the material of the hopper will be released. 8. The bottling-weigher itself, according to the previous claims, characterized by having the frame some wheels for comfortable movement, as well as being all the sides of the frame adequately coated for greater protection. 9.a transportable automatic weigher-weigher.
