Abstract
Abstract The tube conveyor according with the invention is made of: wheeled containers with main rolling swivel wheels in form of solid or pneumatic tires disposed like a bicycle - one in front and one in the back, also the wheeled containers have lateral stabilizing swivel wheels; the said container having rotation shafts to allow rotation around a longitudinal axis, this shafts being supported on some journal bearings resting on the said main rolling swivel wheels; the wheeled containers having a cruise position where the said rotation shafts are fixed/indexed to the said bearings by indexing/fixing dogs, these dogs being released/deindexed by cams rigidly associated with the mobile/rotary part of the main rolling swivel wheels, by this being possible to rotate the said containers around the said rotation shafts by the action of a stationary spatial cam when the container are moving in a curve or on a some curved rails, for this, the containers having in their median part some median rollers which could engage the said stationary spatial cam; also, the tube conveyor has transfer loop and a transfer and unloading loop made of rails to guide the container and cams or guide rails for unloading or transfer it from one cube to another; also the tube conveyor has a tubular guideway for loaded containers, a tubular guideway for unloaded containers, a loading unit based on vibratory or apron feeders characterized by the fact that the loading is made either via an unversed y-shaped two legged manifold with diverter flap valve or via a successive set of feeders, the loading itself being made by laying/loading successive layers of material to be transported into the said containers; also, the tube conveyor having pneumatic propulsion means to propel the wheeled containers along the tubular guideway.
The way of operation of the tube conveyor is in principle as follows: the wheeled containers are rolling inside the tubular guideways by the effect of pneumatic forces generated by the pneumatic propulsion means because of the swivel wheels and particularly because of the indexed/fixed shafts to the main rolling wheels, the containers are stable, then center of gravity bringing them back to rolling equilibrium; at the end of the tubular guideway the containers get out from it and enter into the transfer loops, where they are guided/kept in equilibrium by the guiding rails or rollers or unloaded by rotating the body of containers on the said notation shafts, this being possible because these shafts are deindexed from the bearings and because of the action of the spatial cam acting on the said median rollers; also the wheeled containers are loaded by vibratory or apron feeders in motion by feeding successive layers of material into the containers enter into the tubular guideways and continue the cycle.
The invention will be apparent from the following detailed description of invention, reference being made to the accompanying drawings.

TUBE CONVEYOR WITH WHEELED CONTAINERS
~ack~round of the invent1on The present inventlon relates to closed loop tube or plpellne conveyors wlth wheeled contalners w1th dynamlc loading/unloadlng and pneumatlc propul~lon.
Prlor Art There are known ln the art tube conveyors wlth dynamlc loadlng/unloadlng and pneumatlc propulsion.
These tube conveyors use for loading one feeder whlch 1s stopped and started when the contalner passes ln front of lt. That l~ when the gondola of the contalner 19 ln front of the loadlng feeder th1s ls worklng but when the gondola 1~ not ln front of the loadlng feeder, thls ls stopped.
,;Attempts to use a flap valve to commute the loadlng flow from one contalner to another when the bogle~ area was ~,'15 exposed to feeder falled, because of the overlapplng effect of loadlng of the gondolas-wh1ch 1s acceptable ,at the unlt ..;
traln but not at the tubular transport becau~e of the s1ze of containers ~cca 6 - 10 tonnes maxlmum now (1990) compared wlth l0Q tonnes for the unlt traln gondolas). ',~
~0 Al-~o another disadvantage of the one feeder loadlng ;' ' sy~tem ls that thls ls llmlted ln termq of flow rate - 2 0 2 ~ ~ ~
(say cca 3000 tph). Thls because there ls a lImltatlon of the gondola speed and also of the feeder speed.
Also there are known tube conveyors wlth dynamlc unloadlng essentla11y lnvo1vlng a follower assoclated wlth gondola whlch together rotate to dump or bottom dump the gondola.
Thls unloadlng system operates ln stralght 1lne and It ls difflcu1t to operate the follower because Its extractlon ls lnterferlng with the gaskets of the wheeled contalners.
The above dIsadvantages are ellminated by the present lnventlon by the fact that the tube conveyor according wlth the lnventlon Is made of: wheeled contalners wIth maln rolllng swlvel wheels ln form of solid or pneumatlc tlres dlsposed lIke a blcycle - one ln front and one ln the back, a1so the wheeled contalners have lateral stabi1lzlng swlvel wheels; the saId contalner havlng rotatlon shaft~ to allow ~otatlon around a longltudlnal axIs, thls shafts belng supported on some ~ournal bearlng~ restlng on the saId maln rolllng swlve1 wheel~; the wheeled contalners havlng a crul~e position where the said rotation shafts are flxed/lndexed to the sald bearlngs by lndexlng/fixlng dogs, these dogs belnq released/deindexed by cams rigidly assoclated wlth the moblle/rotary part of the maln rolllng ~wlvel wheels, by thIs belng possIble to rotate the saId ~5 contalners around the ~ald rotatlon shafts by the actlon of a statlonary spatlal cam when the contalner are movlng ln a .. . - . .. . . .. - .. ~ :. ~ . , - . . .

havlng ln thelr medlan part some medlan rollers whlch could engage the sald statlonary spatial cam; also, the tube conveyor has transfer loop and a tran~fer and unloadlng loop S made of ralls to gulde the contalner and cams or gulde ralls for unloadlng or tran~fer lt from one cube to another; also the tube conveyor has a tubular guldeway for loaded contalners, a tubular guldeway for unloaded contalners, a loadlng unlt based on vlbratory or apron feeders characterlzed by the fact that the loadlng ls made either vla an lnversed y-shaped two legged manlfold wlth dlverter flap valve or vla a successlve set of feeder~, the loadlnq ltself belng made by laylng/loadlng successlve layers of materlal to be transported lnto the sald contalners; also, lS the tube conveyor havlng pneumatlc propulslon means to propel the wheeled contalners along the tubular guldeway.
The way of operatlon of the tube conveyor ls ln prlnclple as follow~: the wheeled contalners are rolllng `~ lnslde the tubular guldeways by the effect of pneumatlc ~; : 20 forces generated by the pneumatlc propulslon means because of the swlvel wheels and partlcularly because of the lndexed/flxed shafts to the maln rolllng wheels, the .contalners are stable, then center of gravlty brlnglng them back to rolling e~ulllbrlum; at the end of the tubular :

~ack~round of the invent1on The present inventlon relates to closed loop tube or plpellne conveyors wlth wheeled contalners w1th dynamlc loading/unloadlng and pneumatlc propul~lon.
Prlor Art There are known ln the art tube conveyors wlth dynamlc loadlng/unloadlng and pneumatlc propulsion.
These tube conveyors use for loading one feeder whlch 1s stopped and started when the contalner passes ln front of lt. That l~ when the gondola of the contalner 19 ln front of the loadlng feeder th1s ls worklng but when the gondola 1~ not ln front of the loadlng feeder, thls ls stopped.
