Definitions

  • Each swivel or hinge joint mechanism embodies at least two components which are rotatable relative to one another, wherein one component is fixed with the suspension mechanism of the traveling carriage and the other free component is at least partially enclosed by the associated support holder.
  • These components of each swivel joint mechanism and the associated support holder are constructed in such a way that the suspended load container is centered with respect to the suspension mechanism in two directions which are approximately perpendicular to one another.
  • load containers conveying material which require a continuous vertical or perpendicular position of the load container are transported at overhead conveyors or trolleys, the track rails of which are not situated solely in one plane, rather are spatially arranged, i.e., possess horizontal, inclined and vertically extending track rails with suitable transfer or transition locations, then it is necessary that the mounting of the load container at the travelling carriage or the like of the suspension or overhead conveyor be constructed in such a fashion that this load container always assumes a vertical position independent of the momentary position of the travelling carriage.
  • Another, more specific object of the present invention relates to an improved apparatus for pivotably mounting a load container at a travelling carriage or the like of overhead conveyors or similar systems which afiords for quick, reliable, and easy mounting and dismantling of the load container at the travelling carriage, affords adequate centering of the load container at the suspension mechanism of the traveling carriage, provides for safe transport and carrying of the loads without danger of the load container dropping off of the system when the conveying operation occurs in different positions or requires the load container to move through different spatial directions, and finally, ensures for a conveying system which is not readily subject to breakdown and extremely capable of performing its intended function.
  • the inventive apparatus of the aforementioned type is generally manifested by the features that it comprises two support holders arranged at the load container and two swivel or hinge joint devices arranged at the suspension mechanism of the travelling carriage or the like.
  • Each of the swivel joint mechanisms advantageously consists of at least two components rotatable relative to one another, one such component being fixedly connected with the suspension mechanism of the travelling carriage of the overhead conveyor and the other free component of which is at least partially surrounded or enclosed by the associated support holder.
  • these components of each swivel joint mechanism and the associated support holder are constructed in such a way that the suspended load container is centered with respect to the suspension mechanism in two directions which are approximately perpendicular to one another.

  • FIG. 3 is a schematic representation of a preferred embodiment of inventive mounting or support apparatus for the load container of an overhead conveying system or the like;
  • FIG. 4 is an enlarged vertical sectional view showing details of one of the schematically depicted swivel joint devices and its associated support holder used in the mounting apparatus for a load container of a travelling carriage of overhead conveyors employed in the system of FIG. 6, and taken substan tially along the line IV-IV thereof;
  • FIG. 5 schematically illustrates in top plan view details of DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Describing now the drawings, in FIGS. 1 and 2 there is represented a known type of mounting arrangement for load containers 1 through the use of hook members 2.
  • the load container 1 will be seen to possess two fixed pin members 3 by means of which the load container 1 can be suspended at the hook members 2.
  • overhead or suspension conveying systems utilizing vertical and horizontal rails, such positional changes of the suspension mechanism with respect to the load container occur, so that a hook-like suspension of the load container is not possible with such type conveying installations.
  • FIGS. 3-6 there is depicted a preferred embodiment of inventive apparatus for the pivotal mounting of a load container at a travelling carriage or the like of suspension or overhead conveyors, trolleys or equivalent structure.
  • reference numeral 4 designates the load container equipped at two sides at its upper edge with a respective support or carrier holder 5 in the form of a trough 5a.
  • Reference numeral 6 designates a frame portion of the partially illustrated suspended travelling carriage at which there is secured a suspension mechanism 7.
  • Suspension mechanism 7 for the travelling carriage arrangement will be seen to comprise a horizontally disposed support element 8 and a respective vertically depending support arm member 9 and 10 arranged at each end of this horizontally extending support element 8. Furthermore, at the free end of each support arm member 9, 10 there is arranged a respective swivel or hinge joint mechanism, designated in its entirety by reference character 50, and composed of the two components 11, 12, wherein the component 11 constitutes a pin member fixed to the suspension mechanism 7, and the other component of each swivel joint mechanism comprises a rotatable disc or plate member 12 secured to the free end of the associated pin member 11.
  • the elements 8-12 collectively 'form the suspension system or mechanism 7 for the load container 4 or the like.
  • each troughshaped support holder 5 when the load container 4 is suspended encircles or encompasses at least partially the associated plate or disc member 12 and bears at two locations upon such associated plate member 12, all as will be more fully explained hereinafter with respect to the discussion of the arrangement of FIGS. 4 and 5.
  • the load container 4 is raised at the loading and unloading station to such an extent that it can travel beneath the suspension mechanism 7 without the plate members 12 contacting the associated support holders 5. Thereafter, this load container 1 is lowered onto and in contact with the plate members l2 and therefore is ready to be transported.
  • F urthermore one noteworthy advantage of thesystem heretofore disclosed and described is the fact that it is not necessary to exactly align and center the load container 4 in order to introduce the plate members 12 into the associated support holders 5. Rather, the load container 4 can be offset by a certain amount and nonetheless the swivel joint mechanisms 50 can be properly joined with the support holders 5, again as will be more fully explained hereinafter.
  • FIGS. 46 inclusive there is precisely described the cooperative relationship of each swivel joint mechanism 21, 18 with its associated support holder 19, corresponding to the support holders 5 of FIG. 3.
  • Support holder 19 is composed of a component forming a substantially roof-shaped trough 22 which is attached to the relevant sides of the load container 23 and reinforced by the wall members 24.
  • FIG. 5 showing in plan view the roof-shaped trough 22, such is composed of four inclined walls 22, 22" and forms a downwardly open pocket for receiving from below the associated plate member 18.
  • each trough 22 having the mutually inclined walls 22', 22" affords a centering of the load container, upon suspension of the load, in two directions which are perpendicular to one another.
  • the wall portions 22 there occurs a lateral centering while the inclination of the transverse wall portions 22" ensure for a centering in a direction which is perpendicular thereto. Consequently, the load containers 23 upon being suspended need not be exactly aligned with the suspension mechanism. It is sufficient if, upon lowering the load container 23, that the plate member 18 extends somewhat into the opening of each associated trough 22 of the associated support holder 19, so that the mutual position of the plate member 18 and trough 22 will automatically occur upon lowering of the load container 23.
  • the plate member 18 bears at the locations 19 (FIG. 4) against the walls or wall portions 22" of the trough 22, whereas at the apex of the trough such plate member 18 is not contacted and is freely disposed by a small amount designated by reference character 51in FIGS. 4 and 6.
  • FIG. 6 there is schematically illustrated one suitable form-of dampening mechanism, designated in its entirety by reference numeral 41, ancl constituting a springloaded friction brake arrangement, thespring tension of which can be adjusted in suitable manner, for instance through an adjustment screw as is well known to the art.
  • the adjustment of the friction brake 41 is advantageously undertaken when the load container is empty and can only be so strong that the empty container always again returns into the vertical or perpendicular position.
  • the plate member 18 should not move relative-to the associated support holder 19 and the associated trough 22.
  • This can be obtained in that the inclination of the walls 22 of the trough 22 (FIG. 5) is chosen such that the braked disc or plate member 18 cannot rotate in its associated trough 22 so that the desired braking action is not relinquished.
  • FIG. 7 A further solution for dampening device is depicted in FIG. 7 wherein a rotatable vane drive is mounted in a circular cylindrical hollow compartment of the disc or plate member of one of both swivel or hinge joint mechanisms.
  • reference numeral 30 designates one of the plate or disc members and reference numeral 31 the closed hollow compartment or space arranged inside or outside of the associated plate or disc member 30, yet fixedly connected therewith and filled with a suitable viscous liquid 32.
  • a rotary vane member 33 is arranged within the hollow space 31, and
  • This rotary vane member33 together with a further web member 31a disposed at the wall of the hollow compartment 31, subdivides this hollow compartment into two chambers or regions 34, 35 communicating with one another via a channel or variable orifice 38.
  • Channel 38 can be throttled to a greater or lesser extent through the agency of a suitable screw member 39.
  • suitable sealing means 36, 37 ensure that the dampening liquid or fluid medium 32, during relative movement of the rotary vane member 33 with respect to the housing 31, can only circulate via the bore or channel 38.
  • the rotary vane drive illustrated in FIG. 7 renders possible relative movements between the load container and the suspension mechanism greater than 180.
  • a weight 40 is advantageously arranged at the plate member 30, this weight serving to always maintain the plate member 30 in the illustrated position independent of the position of the rotary vane arrangement 33. If, for instance, a load container is suspended at a vertical conveying rail or track, then the rotary vane arrangement 33 assumes a position which is displaced by from the position depicted in FIG. 7. When the load is transferred to a horizontal rail or track, then the rotary vane 33 moves back into the position of FIG. 7. Of
  • the weight 40 can be arranged in a different form, for instance, instead of radially enlarging the marginal portion of the plate member 30, as shown in FIG. 7, to axially widen same. While the weight member 40 is shown as an integral part of the associated disc or plate member in the arrangement of F IG, 7, it would of course be possible to use a separate weight.
