Vynález sa týká zariadenia pre reguláciuchodu zhadzovacieho vozíka zakladača hro-mad najma rudišťa a rieši problém rovno-měrného nasýpania a homogenizácie rúd narudišti.BACKGROUND OF THE INVENTION The present invention relates to a device for regulating the discharge carriage of a stacker of a stacker, and solves the problem of equalization and homogenization of ore.

Pri zakladaní hromád pomocou velkostro-jov s krokovým alebo plynulým pojazdomje materiál z prísuvného pásu cez smyčkupresýpaný na pozdlžny pás prechádzajúci pocelej dlžke velkostroja, z ktorého je materiálďalej presýpaný za pomoci pojazdného vozí-ka so smyčkou na krátký vysýpací pás alebonohavicovú výsypku. Rovnoměrný pojazdzhadzovacieho vozíka třeba přerušit vždy, keďdojde k prerušeniu přísunu materiálu na pá~soch, čo sa často nerobí, takže dochádza k ne-rovnoměrnému zakladaniu a tým zlej homo-genizácii materiálu v dósledku porušenia zá-kladných vrstiev. Sú známe pokusy so sní-máním přítomnosti materiálu na páse zapomoci fotobuniek, na ktoré však pósobia inévplyvy a rýchle sa zanášajú prachom. Rov-nako nie je výhodné pre všetky druhy mate-riálov používat kapacitnej elektromagnetic-ké j sondy. Naj častéjšie používaná mechanic-ká regulácia za pomoci páky so závažímpoloženým na ploché gurty v mieste rozety,ktorá je zdvíhaná ku koncovému spínačů prechádiaiúcím mteeriálom, je rovnáte) ne- výhodná. Zariadenie je poruchové a nespo- 1’ahlivé, pretože je vypínač poškodzovanýzvýšenou úrovňou materiálu alebo pri jehokusovosti dochádza k častému vypínaniu.When stacking piles with stepper or stepless traverses, the material from the conveyor belt is slipped through the loop into the longitudinal belt passing through the entire length of the machine, from which the material is further slipped with the help of a trolley with a loop for a short hopper belt. The uniform displacement carriage must be interrupted whenever the supply of material to the rods is interrupted, which is often not done, so that uneven loading occurs and hence poor homogeneity of the material due to the failure of the base layers. Attempts have been made to reduce the presence of material on the belt by obstructing the photocells, but which are affected by other effects and rapidly clogged with dust. It is also not advantageous to use capacitive electromagnetic probes for all kinds of materials. The most frequently used mechanical control by means of a lever with a weight placed on the flat gurts at the point of the rosette, which is lifted to the limit switch by the passing meter, is not advantageous. The device is malfunctioning and unreliable because the switch is damaged by increased material levels or frequent shutdowns when it is bent.

Uvedené nedostatky odstraňuje a problémrieši zariadenie pre uvedený účel podl’a vy-nálezu. Podstata vynálezu spočívá v tom, žezariadenie pozostávajúce z nekonečného pásupřevedeného cez smyčkové bubny pojazdné-ho zhadzovacieho vozíka, pozostáva ďalejz blokovacieho kolesa a zo snímača otáčokna ňom umiesteného, ktorý je zapojený napohon zhadzovacieho vozíka a na pohon po-jazdu zakladača. Blokovacie koleso je ulože-né výkyvné v polohe medzi výškami maxi-málneho zdvihu nezaťaženého a maximálne-ho prehybu zataženého pozdížneho pásu a jevybavené regulátorom snímacej polohy, kto-rý le výholdne umiestený nad ramenom z prí-suvnej strany na konštrukcii zhadzovacie-ho vozíka. Pre automatizáciu šířky zaklada-nej hromady je zariadenie s výhodou vy-bavené koncovými vypínačmi krajných polohhromady umiestnenými na konštrukcii mos-tu přísunového pásu, ktoré sú súčasne zapo-jené na pohon zhadzovacieho vozíka a na po-hon posunu zakladača. Výhodou vynálezu voči doterajšiemu stavu techniky je využitie rotačného plynulého pohybu vyvolaného nutným zdvihom neza- ťaženého pásu v prehybe smyčky a z toho 201304The above mentioned drawbacks are remedied and solved by the device for the stated purpose according to the invention. SUMMARY OF THE INVENTION The present invention is based on a device consisting of an endless belt which is transferred through the loop drums of a traveling dropping carriage, further comprising a locking wheel and a rotary encoder connected to the drive of the dropping carriage and to the drive of the stacker. The locking wheel is mounted pivotally in a position between the maximum stroke heights of the unloaded and the maximum fold of the retracted longitudinal belt and is equipped with a sensing position regulator, which is located above the arm from the sliding side on the shovel carriage structure. To automate the width of the foundation pile, the device is preferably equipped with limit switches of the end positions located on the structure of the feed belt, which are simultaneously connected to the drive of the truck and to the post-feed of the stacker. An advantage of the present invention over the prior art is the use of a rotary continuous motion induced by the necessary lifting of the unstretched belt in the loop fold, and of which 201304

Claims

An apparatus for controlling the operation of a pusher carriage of a pile stacker, comprising a continuous belt conveyed through the loop drums, characterized in that it comprises a pivot wheel (10) pivotably mounted in a semi-elevation with the maximum folding height of the pile and a maximum stroke of the unloaded longitudinal belt (40), further a speed sensor (20) disposed on the blocking wheel (10), which is connected to the drive (31) of the truck (30) and the drive (71) of the stacker. the end position switches 50 of the stack stacked on the stacker drive 71 are positioned. The locking wheel 10 is tilted to the optimum stroke sensing position of the unloaded longitudinal belt 40 by means of the regulator 13. When retracted by the material to be conveyed, the strip 40 folds, with the locking wheel 10 and the roller 11 not rotating. After the belt 40 has been pulled off by the action of the loop springs 33, the belt is pivoted, rotated on the roller 11. The sensor 20 captures the pulse generated between the pulse magnet 14 and the sensing magnet 21, which amplifies the pulse in the amplifier 22a, switches the relay 23, while the pulley drive 31 and the backstop drive 71 are switched off for the duration of the rotation of the ballast 11. In the case of the stacking of stepped stacks, but also of the stacker, a stopping of the operation and returning to the back of the stacker at the end of the determined stack width is provided by end switches 50 which switch the drive 71 of the traveler. The invention can be used for all types of stackers and transports free-wheeling or free-folding belts, which must either be stopped or driven by other overload devices. THE INVENTION

Apparatus according to claim 1, characterized in that the locking wheel (10) is provided with a sensing position controller (13) located above the arm (12) from the infeed side on the demolding structure (32).

2, an electrical pulse is applied, thereby ensuring a reliable positioning of the trolley according to the actual amount of material to be transferred. It will allow the carriage to be switched off and on automatically by any device failure. At the same time, the stacker moves away from the stack stack. An example of an apparatus according to the invention is shown in the accompanying drawings, wherein FIG. 1 illustrates schematically the location of the stripper and the drive carriage, the figures 2 and 3 show the details of the blocking wheel construction with the encoder of the sensing position controller, and FIG. 4 shows the circuit diagram of the limit switch encoder for the drives, including the supply belt bridge. The locking wheel 10 consists of a pulley 11 with a pulse magnet 14 on a circumference located in the swinging arm 12, which is simultaneously suspended on the sensor position controller 13 and on the structure 32 of the collapsing carriage 30 from the feed side. The speed sensor 20 is disposed on the arm 12 or the mounting 32 and comprises a sensing magnet 21, a pulse amplifier 22 and a trip relay 23, which is further connected to the drive 31 of the dropping carriage 30 and the feed mechanism 71 of the stacker 70. 62 of the feed belt 60 are OBJECT

3. Apparatus according to claim 1, characterized in that the limit switches (50) of the extreme positions of the pile located on the structure of the bridge (62) of the feed belt (60) are connected to the drive (71).
