Definitions

  • the present invention concerns a slat conveyor of the kind where the slats jointly con- stitute the belt/carrier surface of the conveyor, where the slats are interconnected so that they by performing a mutual relative displacement in the longitudinal direction of the belt/carrier surface are rotatable about a vertically oriented axis and by a drive unit are moved in a conveying direction between a rectilinear receiving area and at least one rectilinear delivery area, where the slats are carried on frame surfaces disposed close to the sides of the belt/carrier surface, and where the conveyor includes means for making a parallel displacing of the delivery area in relation to the receiving area in running over curving areas.
  • Such slat conveyors are provided in many designs and find wide application within the food industry, where such conveyors are used for forwarding raw materials and finished articles in a production line.
  • There is often a need for performing a parallel displacement of the belt direction which is possible by using the chain links mentioned in the introduction and which each allow a small deviation from the course, the deviation being determined by the shape of the respective chain links.
  • the said belt may thus be guided in a kind of S-shaped course in fixed guides and perform the said parallel displacement of the transport surface of the belt.
  • chain link conveyor the blocking surface of which appears as an open structure where the single chain links are preferably made of smooth plastic or polymer that relatively easily are cleaned and disinfected.
  • the chain link conveyor according to the invention is of course not limited only for use within the food industry.
  • Such a conveyor is characterized in that the slats/belts across the curving areas and a straight section between the curving areas, between the rectilinear receiving area and the delivery area, are supported by a movable support including a first and a second set, respectively, of interspaced, uniform, tapering, inverted and mutually facing support members in pairs, the mutually facing sides of which being largely rectilinear and extending in parallel, and the side edges of which facing away from each other having a curved course, the support members being pivotably suspended to frame surfaces of the receiving area and to the frame surfaces of the delivery area, respectively, and the tapering ends of which being suspended on a movable frame with transverse frame segments carried and pivotably suspended on longitudinal conveyor structures extending in parallel, the transverse frame segments supporting uniform carrier surfaces, the outer sides of which having a mainly straight course lying in the tangential lines for the curved courses, and which transverse frame segments constituting support surfaces for the tapering, mutually facing ends of the support members, and where respective,
  • the delivery area becomes variably pivoting, and the belt is supported during the entire course under the pivoting, and furthermore it is achieved by the support members being identically shaped and inverted that the turning radius occurring in connection with the approximately S-shaped course of the chain conveyor becomes identical, meaning that the article transported upon the carrier surface of the belt is not turned in relation to the centre axis of the receiving area.
  • effecting the pivoting of the delivering area may be done with known means that may perform a transverse displacement of the delivery area, why these are not mentioned here.
  • the longitudinal conveyor structures extending in parallel of the frame may each be constituted by two mutually axially dis- placeable parts that are pivoting suspended to the receiving area and the delivery area, respectively, close to the uniform, inverted curved sections, as it appears from claim 2.
  • the support members may be further axially and displaceably connected to the frame, as it appears from claim 3.
  • the slat conveyor can be adapted with recesses on the support members interacting with downwards projecting gripping means on the slat links that jointly form the belt/carrier surface, as it appears from claim 4.
  • a mutual axial displacement of the mutually displacing parts of the conveyor structures that implies a longitudinal axial displacement of the belt length, so that the carrier surface of the conveyor belt is longest when the parallel displacement is performed to a maximum, and where the said carrier surface will be shortest when the course between the receiving area and the delivery area runs along a straight line.
  • Fig. 1 is an elementary sketch of a slat conveyor as seen from above with variable parallel offset according to the invention
  • Fig. 2 is a top view of the slat conveyor shown in Fig. 1, showing the means for performing the variable parallel offset of the conveyor belt
  • Fig. 3 is a top view of the slat conveyor of Fig. 2 in pivoted condition
  • Fig. 4 is a side view of the conveyor shown in Fig. 2, including an automatic belt length regulating unit
  • Fig. 5 is a top view of a conveyor structure of a part of the conveyor
  • Fig. 6 is a simplified side view of the slat conveyor according to the invention with the delivery area in different positions in relation to a permanently located re- ceiving area; and
  • Fig. 7 is a section on the line A-A in Fig. 2.
  • Fig. 1 is a top view of a slat conveyor 2 according to the present invention.
  • the carrier surface 4 of the conveyor is constituted by uniform slats/links 3 that are assembled in a known way, and the slats/links 3 are connected so that they by performing a mutual relative displacement in the longitudinal direction of the belt/carrier surface are pivoting about a vertical axis 5.
  • the carrier surface/belt is drawn in the conveying direction 8 by a drive unit 6, cf. Fig. 3.
  • the conveyor 2 includes a rectilinear receiving area 10 and corresponding rectilinear delivery area 12.
  • the delivery area 12 may be displaced in lateral direction, and, as it also appears, to a delivery area situated at the same distance from the receiving area 10.
  • the carrier surface runs over two curving areas 16, 18 and a straight run 19 between the said curving areas 16, 18.
  • Fig. 2 showing the carrier surfaces for the chain link conveyor 2 according to the invention
  • the means for controlling the carrier surface 4 of the belt appear.
  • the belt is guided/supported in the receiving area 10 by carrier faces 14 constituted by plane surfaces/frame parts 38, 40, and in the delivery area 12 of the faces 14' that are constituted by plane surfaces/frame parts 40, 42.
  • the receiving area 10 is fixed, whereas the position of the delivery area in relation to the orientation of the receiving area is variable in lateral direction, as it appears from Fig. 1 and in more detail from Fig. 3.
  • the belt 4 of the slat conveyor is supported/controlled over the course in the curving areas 16, 18 and the straight section 19 between the curving ar- eas, between the rectilinear receiving area 10 and the delivery area 12, by a first and second set of interspaced, uniform, tapering, inverted and flat support members 20, 22, 24, 26 in pairs facing each other, respectively, their side edges 30, 32, 34, 36 facing away from each other having a curved course.
  • the support members are pivotably connected to the frame surfaces 38, 40 of the receiving area and to the frame surfaces 42, 44 of the delivery area.
  • the tapering ends of the support members 20, 22, 24, 26 are pivotably and displaceably connected to transverse frame segments 27 of a frame 28 which is supported on longitudinal conveyor structures 29 oriented in parallel.
  • the conveyor structures 29 are, as seen in Figs. 2, 3 and more detailed in Fig. 5, con- stituted by a first and a second mutually axially displacing part 31, 33, which are pivotably suspended on the receiving area 10 and the delivery area 33, respectively, close to the uniform, inverted curving sections 58, 60, cf. Figs. 2 and 3.
  • the conveyor structures 29 become longitudinally variable, which means that the delivery area 12 can be placed on the same line/vertical plane, irrespectively of its degree of pivoting.
  • the respective rectilinear receiving and delivery areas each include uniform, inverted curving sections 58, 60, 62, 64 with rounded side edges 66, 68, 70, 72 that are disposed at a level over the support members 20, 22, 24, 26, cf. Fig. 4, but below the level for the carrier surface 4 of the conveyor.
  • the curving sections 58, 60 thus contribute to guide the belt from the rectilinear course in the receiving area 10 over to the first curving area 16, and the curving sections 62, 64 contribute to guide the belt 4 from the second curving course 18 to the parallel offset delivery area 12.
  • Displacing the delivery area 12 in lateral direction relative to the receiving area 10 is performed by displacing the frame 28 by known means, such as a piston, drive motor or similar, as outlined in Fig. 1.
  • a lateral displacement of the delivery area 12 in the shown embodiment of the chain link conveyor according to the invention will entail a combination of a lateral and an axial displacement of the first part 31 and the second part 33 of the con- veyor structures 29 and the support surfaces 50, 52, 54, 46 for the support members 20, 22, 24, 26 on the transverse frame segments 27 of the frame 28, respectively, in relation to the conveying direction 8 of the conveyor.
  • the advantage hereby is that the delivery area 12, irrespectively of the degree of the variable pivoting of this will lie on a line or a in a vertical plane, both of which are indicated with line 80 in Figs. 2 and 3.
  • Fig. 7 is a cross-sectional view along the line A-A in Fig. 2, it is seen that at least the curved courses 30, 32, 34, 36 of the support members 20, 22, 24, 26 (but typically all of the support surfaces) on the side facing away from the support surface 4 of the conveyor belt a recess 74 that interacts with gripping means 76 on the side of the links 3 facing the support surfaces.
  • the gripping means 76 engage the recess 74 and thus prevent the belt from lifting during passage of the curved lengths 16, 18.
  • the chain link conveyor 2 includes a lifting/lowering unit (not shown) so that delivery of articles transported on the support surface 4 of the conveyor may take place at several levels by elevating and lowering the delivery area 12.
