Definitions
- the present invention relates to a conveyor compris ⁇ ing a stationary track the extent of which comprises sections at different levels, movable elements which are guided by the track for movement along this, a supporting member on at least some of the movable ele ⁇ ments, and a device for maintaining the supporting mem ⁇ ber in a predetermined angular position regardless of the position of the movable element during its movement along the track, wherein the supporting member is mounted for rotation about a substantially horizontal axis in the movable element, and wherein the device for main ⁇ taining the supporting member in the predetermined posi- tion comprises an actuating mechanism connected with the supporting member, and a guide track arranged wholly or partially along the stationary track to interact with the elements in the actuating mechanism.
- conveyors of this type for the transportation of goods in a predetermined posi ⁇ tion along a track which extends for example between different dwellings in a building.
- transportation we can mention the transportation of pro ⁇ ducts within a factory between different production sta- tions and the conveyance of ready-laid trays in hospi ⁇ tals and similar service arrangements between a central kitchen and different wards.
- a conveyor of the type mentioned above is known previously from DE-OS 2429282 and more particularly re- lates to. the conveyance of batches of newspapers between different processing stations.
- This known conveyor has several disadvantages.
- the supporting member which has to be kept in a predetermined angular position during transportation along the stationary track is not reliab- ly positively-controlled in order to maintain the prede- ter ined (in this case vertical) position along the track.
- the object of the present invention is to provide a conveyor of. the type referred to above, which can easily be run along an arbitrary path extending between different levels and having more or less complicated runs at each level , and in which the movable elements with the supporting members mounted thereon are reliab ⁇ ly and infinitely-variably controlled so as to positive ⁇ ly maintain the predetermined position of the supporting member in each position in the stationary track by means which require minimum maintenance and which eliminate the risk of inadvertent manipulation and the risk of the movable elements binding during their movement or jamming at any point along the movement path.
- FIG 1 is a perspective view of a section of a con ⁇ veyor in accordance with the invention
- FIG 2 is a front view of this section
- FIGS 3 and 4 are enlarged vertical cross sectional views along the lines III - III and IV - IV in FIG 2;
- FIG 5 is a fragmentary front view, partially a ver ⁇ tical cross sectional view, of the conveyor;
- FIG 6 is a corresponding plan view, partially a horizontal cross sectional view, of the conveyor,
- FIGS 5 and 6 being on the same scale as FIGS 3 and
- FIG 7 is a fragmentary front view, partly a verti ⁇ cal cross sectional view, of an alternative embodi- ment with locking arrangement
- FIG 8 is a vertical cross sectional view along the line VIII - VIII in FIG 7;
- FIG 9 is a frontal view of a section of a conveyor in accordance with a modified embodiment of the invention.
- FIG 10 is a front view of a larger section of the conveyor shown in FIG 9.
- FIG 11 illustrates a cross sectional view along the line XI - XI in FIG 9.
- the conveyor shown in FIG 1 comprises a stationary track in the form of a slotted box profile 10 with rear wall 11, upper wall 12, lower wall 13 and two front walls 14 which are in the same plane but are spaced so that they confine a slot 15 which extends along the box pro- file.
- This box profile can be assembled with the rear wall 11 fixed against a wall in a building or can be supported in stationary fashion in some other way. It can be curved in the vertical o r horizontal direction so as to follow the desired transportation path which can extend between different levels and on each level can deflect to one or other- side in an arbitrary pattern.
- Each trolley 16 comprises a plate 18 of rectangular shape which is provided at each corner with a welded-on bearing member 19.
- a support roller 22 is rotably mounted by means of a shaft 21, said roller being arranged to run against the upper and lower walls 12 and 13,respec- ively, and on the outside of the bearing member a roller bearing 23 is provided which is mounted on the bearing member by means of a lock ring 24 and is designed to run against the rear wall or the front walls 11 and 14, respectively.
- each link 17 is designed as a fork 25 which straddles the edge of the plate 18 and which is connected to the plate by means of a universal joint 26, as shown in FIG 6, so that the trolleys are free to move relative to each other without being impeded by the connection between them provided by the links.
- a cylindrical device 27 with an end wall 28 is rotably mounted in a circular aperture centrally in the rectangular plate 18.
- Mounting is provided by means of two lock rings 29 which are accommodated in grooves 30 in the member 27 on each side of the plate 18 and which hold two rings 31 against the opposite sides of the plate with inserts of plain bearing rings 32 made for example of Nylon between the rings 31 and the plate.
- a cylindrical plain bearing bushing 33 made for example
- the end wall 28 which is connected with the member 27 supports centrally a shaft 34 which projects axially from the end wall, the shaft forming the supporting member for a plate 35 which is fastened to the shaft in a recess 36 in the free end thereof.
- a cylindrical gear wheel 37 is rotably mounted, having chamfered ends 38 on the gears, and the shaft 39 of this gear wheel is transverse to the shaft 34 and thus to the rotational axis of the member 27 and it is also transverse to the plane of the plate 35.
- a rack 40 is arranged on the inside of the rear wall 11 of the box profile 10, said rack extending along the rail with the teeth thereof all arranged ver- tically.
- the cylindrical member 27 which is rotably mounted in the plate 18 is constant- ly kept in a certain position in space with the plate 35 in the horizontal position, regardless of whether the trolley changes from the horizontal position to more or less vertical position.
- the gear wheel 37 is always maintained with the teeth vertical , since these engage the vertically arranged teeth on the rack 40.
- the gear wheel 37 In a curve in the vertical direction the gear wheel 37, whilst simultaneously rolling against the rack 40, will be uni pededly moved in the vertical direction relative to the rack together with the trolley as this moves in the vertical direction, and when the trolley proceeds absolutely vertically, the gear wheel will not roll at all but instead will be displaced along the vertical teeth of the rack.
- the plate 35 is maintained constantly in the horizontal position regardless of the position adopted by the trolley, because the location of the plate is fixed as a result of the engagement between the teeth of the gear wheel 37 and the rack 40 in each position of the trolley along the track 10.
- tooth guidance is required only in the curves made by the rails in the vertical direction, whilst guidance can be provided with other and simpler means in the absolutely vertical and the absolutely horizontal portions of the rail.
- end wall 28 there are pins 41 with rotably-mounted cam rollers 42.
- stationary angle profiles 43 are arranged, with one flange fastened to the walls 14, whilst the other flange projects from the angle profile, so that these flanges form a guide groove on the front of the box profile.
- the flanges are arranged at an angle in respect of each other over shorter sections 43'.
- the cam rollers 42 run in between the angle profiles the distance between the projecting flanges being so adjusted that the cam rollers .42, rolling against the flanges, keep the rotable device 27 in the predetermined angle of rotation.
- the guidance function is thus removed completely from the gear wheel/rack and accordingly the rack can in these sections be dispensed with completely, or perhaps also they can be maintained but made considerably narrower if it is wished to main ⁇ tain continuous tooth engagement over the entire length of the track.
- a locking mechanism 141, 142, 143 can be arranged between the trolley 116 and the shaft 134 (FIGS 7 and 8).
- the trolley is shown built up from two side plates 118, which do not prevent the locking mechanism being employed in conjunction with the trolley described
- FIG 7 illustrates the components forming part of the locking mechanism,' such as a detent hook 141, and a circular disc 142 with recesses 143 provided therein.
- the disc 142 is rotary together with the shaft 134.
- the detent hook 141 is loaded by means of the spring 146, so that the detent hook engages reliably the re ⁇ cess 143 when the trolley 116 adopts a horizontal or vertical position, or in transport paths where the in- clination is for example 45°, a position corresponding to this inclination.
- the function of the locking mechanism is as follows Just before the trolley 116 reaches a vertical rail radius, the gear wheel engages with the rack 140 (FIG 8). After reliable engagement has occurred and be ⁇ fore the rail radius starts a pulley 144 which is con ⁇ nected with the detent hook comes into contact with an entrance chamfer 145 of the rack whereby during the continued movement the detent hook is lifted to dis- engage the recess 143 so as to permit rotation of the shaft 134 which is connected with the disc, relative to the trolley 116.
- FIGS 9 - 11 differs from the embodiments previously described mainly in that the rack 40 and the gear wheel 37 with its bearings are replaced by a guide track 243 with teeth designed to interact directly with an external adjustment device 242, 252 forming part of an actuating mechanism also comprising a reduction gear between the adjustment de ⁇ vice and the supporting member 34.
- the track has been made open and consists of two tubes 213 which at a suitable spacing are held together by spacers 211.
- a track of this type can of course also be employed in the embodiment with rack initially described.
- the trolley 216 consists of two plates 218 which are held together partly by a central boss 244 and partly by a distance boss 245 and by two end tubes 246.
- U-shaped straps 246 are rotably mounted at each end of the latter. Each strap functions as a bearing for a runner wheel 222 having a shape adapted to suit the track formed by the two tubes 213.
- the hub 244 of the trolley 216 forms the mounting for the supporting member or shaft 34, on which a plate can for example be provided.
- An internally-toothed wheel rim 254 is fastened to the shaft 34, engaging a smaller gear wheel 248, the shaft 249 of which is mounted in the distance boss 245.
- a larger gear wheel 250 which engages with an internal gear wheel 251 mounted on the hub 244 is fastened to the same shaft.
- a roller holder 252 with four symmetrically arranged pins comprising mountings for four rollers 242 is fastened to the inner gear wheel 251. These rollers together with the roller holder 252 form a 4-toothed "gear wheel" which during the movement of the trolley along the track interact with a guide rail 243. As shown in FIG 10 this rail is straight along
- the guide rail or guide track 243 is designed as a gear rim.
- the gear wheel 242 as a result of its engagement with the gear rim is forced to rotate.
- This rotational movement results in rotation of the gear wheel 251, the pair of gears 250, 248 and of the gear wheel 254 with the shaft 34 fastened therein.
- pitch of the gear rim 243 and of the reduction ratio between the gear wheels 251/250 and 248/254, respectively it is possible to obtain rotation of the shaft 34 which exactly compensates for the rotation .imparted to the trolley during its passage along the curved track.
- the trolleys 216 are held together so as to form an endless chain by means of links 217 and possibly intermediate trolleys 253.
- the "gear wheel” 242 can be designed in the same way as a conventional gear wheel with several teeth. By selecting only four teeth however, two of these can advantageously be employed also for guidance along the straight portions of the track.
- Driving of the endless chain can be brought about by automatically engaging for drive purposes the trolleys with an endless pulling device which extends along the straight portion of the conveyor path or, in the case of the embodiment of the conveyor initially described, by virtue of the fact that the gear wheels 37 are pro- vided with drive motors, at least on some trolleys.
