- The present invention relates to an improved apparatus for building up and discharging bulk material.
- The prior art apparatus for handling bulk material as located at a storage site have several versions of the well known stacker-reclaimer apparatus. Many of these apparatuses, as shown in
FIG. 1 , have a central column to which the stacker and reclaimer are connected via bearings. These apparatuses with a central column require at least three bearings to separately operate the reclaimer from the stacker. Bearings of the size needed to function in a stacker-reclaimer apparatus can cost in excess of $100,000.00. A configuration of the apparatus that would reduce the number of bearings without adding additional columns would provide a financial advantage. See also U.S. Pat. No. 4,363,396. In this embodiment, a circular rail functions as the third bearing to support the reclaimer. - Another version of the stacker reclaimer apparatus as described in U.S. Pat. No. 4,629,060 uses an incline column to replace the central column and torque arm. In this configuration there is only one stacker bearing as the stacker weight is carried by the incline column. An additional incline column, however, substantially raises the cost of the apparatus.
- In another embodiment, shown in U.S. Pat. No. 4,244,463 uses a fixed center column attached to a foundation. In this apparatus, the stacker, reclaimer and wing feeder unit each have one bearing which are stationarily mounted to the fixed column to permit all three units to rotate independently.
- The present invention provides an improved stacker-reclaimer apparatus wherein only one stacker bearing separates the stacker machine from the reclaimer machine. This is accomplished by applying the end of a torque reaction member at the column as a loose member around the upper stacker column. More specifically, a stacker-reclaimer apparatus is provided which is made of a stacker machine having an upper column and a lower column, wherein the upper column and lower column are connected through a stacker bearing. The apparatus is also made of a torque reaction member rotatably connected to the stacker upper column. A torque reaction member is rotatably connected to the upper stacker column via a torque arm bearing frame. The torque arm bearing frame is connected to a plurality of rollers. The vertical rollers contact on a circumferential support member which is fixedly attached to the stacker upper column. The horizontal rollers contact the outer periphery of the circumferential support member. In an alternative embodiment, plastic slides can be used instead of rollers. The slewing motion can be controlled by a rotational drive assembly connected to the torque reaction member. Additionally, the apparatus is made of a reclaimer machine positioned to support the stacker lower column.

FIGS. 2A, 2B , and 3, a stacker-reclaimer apparatus 1 is an apparatus for conveying loose bulk material such as wood chips or gravel from a first location to a second location. In the preferred embodiment of the present invention, astacker machine 10 is shown having a stackerupper column 12 and stackerlower column 14. A stacker rotational bearing 20 is mounted to stackerlower column 14. The stackerupper column 12 is rotatably mounted to stacker bearing 20. The stacker bearing 20 allows thestacker machine 10 andreclaimer machine 16 to slew independently. The stacker bearing 20 is ball or a roller bearing. Thereclaimer machine 16 is below, but not shown in detail. - A
torque reaction member 21 is made of anarm portion 18 and a torque arm bearingframe 19. Thetorque arm 18 projects perpendicularly away from the stackerupper column 12 and can be attached to anexternal support leg 28. A torquearm reaction member 21 functions to support and counteract the torque reaction generated whenstacker machine 10 is rotated. Typically referred to in the art of stacker-reclaimers as a torque arm, atorque reaction member 21 connects a portion of the stacker-reclaimer apparatus 1 which should be prevented from rotating to a fixed point relative to the ground. Since large torques can be generated in the operation of the machine, a longtorque reaction member 21 is usually required. Atorque reaction member 21 in the context described herein provides a stationary mount for the stackerrotational drive assembly 25 so that rotational commands can be imported to the stackerupper column 12 andstacker boom 10 without rotational motion being transferred from the stackerlower column 14 orreclaimer 16 or vice versa. Alternatively,torque arm 18 and torquearm bearing frame 19 can be made as one unit rather than as two distinct pieces. - The torque
arm bearing frame 19 is sized to surround and is applied as a loose member around the stackerupper column 12. The term sized to surround the upper stacker column means that the torquearm bearing frame 19 surrounds theupper stacker column 12 but does not contact it. This is accomplished in the preferred embodiment by providing acircumferential support member 29 attached to the stackerupper column 12 fixedly disposed below the torquearm bearing frame 19.Circumferential support member 29 is a substantially horizontal surface fixedly attached to a stackerupper column 12. In a preferred embodimentcircumferential support member 29 is a metal plate stiffened with gussets (not shown) underneath the plate to support the weight of thetorque arm 18 and torque arm bearing frame 19 (which encircles the stacker column 12). Further to the preferred embodiment, thecircumferential support member 29 is constructed of two plates with gusset plates arranged in between the plates to form a stiff structure. Yet further to the preferred embodiment,circumferential support member 29 containsbull gear 31 along its circular periphery. - The
torque reaction member 21 is rotatably connected to the stackerupper column 12. In the preferred embodiment, this rotatable connection is achieved by using a plurality ofvertical rollers 38 connected to the torquearm bearing frame 19. The plurality ofvertical rollers 38 are connected to the torquearm bearing frame 19 by means ofbrackets 39. Thebrackets 39 are sized and positioned to provide support for the plurality ofvertical rollers 38 as they contactcircumferential support member 29. Thevertical rollers 38 rest on the top surface ofcircumferential support member 29. In this embodiment, there are at least two vertical rollers. Additionally, a plurality ofhorizontal rollers 35 are connected to the torquearm bearing frame 19 and roll horizontally on the periphery ofcircumferential support member 29. The plurality ofhorizontal rollers 35 are connected to the torquearm bearing frame 19 by means of brackets or adapter blocks 40. Thebrackets 39 are sized and proportioned so as to position the plurality ofhorizontal rollers 35 to contact the portion of the outer periphery of thecircumferential support member 29 on which the plurality ofhorizontal rollers 35 roll. - The
circumferential support member 29 may have a step or shoulder on which the plurality ofhorizontal rollers 35 make rolling contact that is either larger or smaller in diameter than the exact outer periphery of thecircumferential support member 29. More specifically, the torque armbearing frame portion 19 supports a plurality ofvertical rollers 38 and a plurality ofhorizontal rollers 35 in positions concentric with stackerupper column 12. The plurality ofvertical rollers 38 allow thetorque arm 18 to sit on thecircumferential support member 29. - In this invention, the
torque arm 18 also functions to support stackerrotational drive assembly 25 made up of motor andbrake 22,speed reducer 24 andpinion gear 30. The end of thetorque arm 18 is attached to asupport leg 28, which typically supports the bulk material infeed conveyor, not shown in detail. Thebull gear 31 ofcircumferential support member 29 is attached to theupper column 12 and is in mesh withpinion gear 30. Thus, to control the stackerupper column 12, a motor assembly including a motor andbrake 22,speed reducer 24 andpinion 30 are mounted on the torquearm bearing frame 19 in the preferred embodiment. Thedriver pinion 30 is operably connected to thebull gear 31 of thecircumferential support member 29 to power the rotational movement of the stackerupper column 12 andstacker machine 10. Thehorizontal rollers 35 function to keeppinion gear 30 in proper mesh with thebull gear 31 ofcircumferential support member 29. Thevertical center axis 11 of theupper stacker column 12 and thevertical center axis 23 of thestacker drive assembly 25 are parallel. - The
torque arm 18 does not move since the far end is attached to asupport leg 28 which typically supports the infeed conveyor (not shown). However, the stackerrotational drive assembly 25, which is made of the motor andbrake 22, andspeed reducer 24 andpinion gear 30 are fixedly attached to thetorque arm 18 so that torque from thepinion gear 30 can be applied to thebull gear 31 which connected to the stackerupper column 12, resulting in rotation of stackerupper column 12 and hence thestacker conveyor boom 10. - Now referring to

The plurality of vertical rollers roll on the top ofcircumferential support member 29.Horizontal rollers 35 are connected throughbracket 40 to torquearm bearing frame 19 and roll around outside edge ofbull gear 31. Motor andbrake 22,speed reducer 24 andpinion gear 30 are shown attached totorque arm 18 and torquearm bearing frame 19. - Now referring to
FIG. 4 ,torque arm 18 and torquearm bearing frame 19 can be seen supporting attached plurality ofvertical rollers 38 and plurality ofhorizontal rollers 35 which roll on the top surface and outer edge, respectively ofcircumferential support member 29 andbull gear 31. The stacker-reclaimer drive assembly 25 can be seen from the top attached totorque arm 18 and torquearm bearing frame 19. The plurality ofvertical rollers 38 and the plurality ofhorizontal rollers 35 keep torquearm bearing frame 19 concentrically located with respect to stackerupper column 12. The plurality ofrollers FIG. 3 ) in proper mesh withbull gear 31 ofcircumferential support member 29. - Now referring to

A plurality ofvertical guides 105 support part of the weight of the end oftorque arm 18 and torquearm bearing frame 19. A plurality ofhorizontal guide 100, in the preferred embodiment, are positioned to contact theupper stacker column 12. In an alternate embodiment, the plurality ofhorizontal guides 100 are positioned to contact (not shown) thecircumferential support member 29.
