Definitions

  • This invention relates to conveyors formed by a pair of spaced, substantially parallel belts, and more particularly, to such conveyors having reversed or zigzag travel.
  • Conveyor belts are used for two principal pur ⁇ poses: to transport materials from one point to a different point or to carry materials through a processing zone.
  • the length of a conveyor is obviously fixed by the distance between the two points when the purpose of the conveyor is simply to transport material therebetween.
  • time becomes an important factor in determining the length of the conveyor. For example, to achieve a desired processing " result and at the same time to maintain a desired production rate (pounds or other units per hour) a conveyor with a length of 150 feet may be required.
  • This conveyor not only will take up a great deal of valuable floor area in a building but worse yet will require a building having at least one dimension in excess of 150 feet. Consequently, such a long process ⁇ ing conveyor is burdened with high capital and overhead costs.
  • a principal object of this invention is to reduce the floor length requirement of a processing conveyor.
  • Another important object is to hold ' the material on the processing conveyor in place while undergoing treatment.
  • a further object is to turn the material on the conveyor upside down during treatment.
  • a conveyor is " formed by a pair of spaced, substantially parallel belts having at least one reversal or U-turn in their travel.
  • the conveyor of this invention will generally have several U-turns so that it travels along a zigzag course.
  • the belts used in the conveyor of this invention are preferably perforated or reticular.
  • Bulletin 148 of Cambridge Wire Cloth Company in Cambridge, Maryland shows metal mesh belts in various weaves which are well suited for the conveyor of this invention.
  • Wire Belt Company of America in Winchester, Massachusetts, selLs a belt under the registered trademark Flat-Flex which is formed of stainless steel wire into a mesh having roughly rectangular openings approximately 0.4 inch wide and 2 or more inches long.
  • Flat-Flex belt is particularly preferred for many uses of the conveyor of this invention.
  • the inner, belt at each U-turn is wrapped around a driven gear or sprocket, the teeth of which.mesh with openings in the belt.
  • the inner belt at each U-turn or reversal is positively driven.
  • the outer belt at each U-turn slides around a fixed arcked member or shoe which keeps the outer belt spaced from the inner belt at the U-turn the same distance that is maintained between the two belts in their straight parallel portions or stretches.
  • each shaft on which the belt sprockets are mounted is provided with rotational drive means such as an electric motor but preferably a power sprocket with a power chain. It is essential that all the belt sprockets in the conveyor system be driven at the same rotational speed. For this reason, power sprockets with power chains forming a single power train driven by one electric motor are preferred for achieving synchronous rotation of all the belt sprockets or gears.
  • Means for rotating several shafts in synchronism are well known and need no further explanation herein, particularly inasmuch as the drive for the shafts at the several U-turns in the paired belt con ⁇ veyor is not part of this invention.
  • the inner belt driven at one U-turn becomes the outer belt sliding around the shoe of the next U-turn in the travel of the conveyor
  • the outer belt sliding around the shoe of the first- mentioned U-turn becomes the inner belt driven at the second-mentioned U-turn.
  • the two belts will again change positions relative to the belt sprocket and shoe of' the U-turn.
  • the belt sprockets and shoes may be made of metal or plastic as known for such drive and guide means.
  • belt sprockets may be positioned in the central portion as well as in the marginal portions of the inner belt at a U-turn-, two arcked guides or shoes are positioned to contact only the two marginal portions of the outer belt so that the two shoes do not obstruct the material being carried around the U-turn by the central portion of the paired belts.
  • the straight portion of the paired, spaced belts extending from one U-turn to the next U-turn will herein be referred to as a pass of the novel conveyor.
  • the paired, spaced belts forming the conveyor with zigzag travel according to this invention may also be simply referred to as the multipass conveyor.
  • the portion of a single conveyor belt extending from one rotary device to another rotary device will be called a run which is a conventional term. While the multiple passes of the novel conveyor are usually horizontal, they may in some cases be vertical or at any desired angle thereto.

  • Position 27 of belt run 2B provides the place where material is deposited for treatment while being transported by the conveyor.
  • Sprockets 20,21 rotate clock-- wise so that material placed on belt run 2B at position 27 is carried under sprocket 10.
  • the material is captured between parallel belt runs 2A,2B which travel at the same speed toward the U-turn around sprocket 21.

Likewise, a pair of rectangu ⁇ lar containers 63 may be positioned adjacent wall 45 and on opposite sides of the conveyor pass moving toward belt sprocket 49 in zone Y. Containers 63 may be filled with insulation so that heat stored in the cooked ravioli and conveyor coming from zone X is not dissipated to the water in zone Y but rather is transferred to the cold water flowing from zone Y into zone X.

  • the up-and-down zigzag path of the conveyor shown in Fig. 6 can also be used in a liquid bath. If such a vertical arrangement would be applied to the two- zone tank of Fig. 4, it would be possible to have dividing wall 45 without slots 60,61 by having the last upward pass of the conveyor in zone X adjacent wall 45 travel around a belt sprocket positioned above the top of wall 45 so that the next downward pass of the conveyor enters zone Y adjacent the other side of the wall 45. This arrangement is desirable when different liquids are used in zones X and Y. Accordingly, only such limitations should be imposed on the scope of the invention as are set forth in the appended claims.

Abstract

Un convoyeur suivant un cheminement en zigzag se compose de deux bandes transporteuses continues (A, B) et est particulièrement utile dans le traitement de matériaux. Chaque bande (A, B) présente des ouvertures le long de ses parties marginales et un ensemble de roues dentées entraînées (10-15, 20-26) en prise avec les ouvertures. Une partie de la longueur de cette bande est maintenue parallèle et écartée d'une partie de la longueur de l'autre bande ou les deux bandes forment ensemble un cheminement en zigzag présentant un ou plusieurs virages en U. A chaque virage en U, une bande (A, B) tourne sur les roues dentées (10-15, 20-26) et l'autre tourne en faisant coulisser ses parties marginales autour de guides courbes (34). Les parties restantes des deux bandes (A, B) sont séparées l'une de l'autre et forment des emplacements permettant de déposer un matériau sur le convoyeur ou de l'en retirer.
