Pod koTajnicou 1 je umiestnená pohonná jednotka 1.6, ktorá cez převody poháňa navíjací bubon, resp. reťazové koleso 17, z kterého vedie cez vodiace kladky, resp. retazové kolesa lano, resp. reťaz 18 pozdíž kolajnice 1 k obidvom stranám vozíka.Under the rail 1 is located a drive unit 1.6, which drives the winding drum or the winding drum. a sprocket 17 from which it guides via guide rollers, respectively. chain wheels rope, resp. a chain 18 along the rail 1 to both sides of the trolley.

Pričom jeden koniec lana, resp. retaze 18 ukončenej lanom, je vedený cez vodiacu kladku, resp. reťazové koleso na začiatku kolejnice 1 a vodiace kladky 11, 12, 13, 14, 15 pod základovou doskou 4 a, na jej boku a cez vodiacu kladku G na konzole 5 ku sklopnej narážke 3, kde je lano 18 ukotvené. Druhý koniec lana, resp. reťaze 18 od navíjacieho bubna alebo reťazového kolesa 17 je vedený cez pevné vodiace kladky, respektive reťazové kolesá 23, 24 a pohyblivá vodiacu kladku, resp. reťazové koleso 25 so závažím 26 uložená vo vedení na spodku kolajnice 1, ďalej je lano, resp. reťaz 18 vedené cez vodiacu kladku, resp. reťazové koleso 27 na konci kolajnice 1 spát k druhému konců vozíka, kde je ukotvené.One end of the rope, respectively. chain 18 terminated by a rope, it is guided through a guide pulley, respectively. the sprocket at the beginning of the rail 1 and the guide pulleys 11, 12, 13, 14, 15 below the base plate 4a, on its side and via the guide pulley G on the bracket 5 to the hinged stop 3 where the rope 18 is anchored. The other end of the rope, respectively. of the chain 18 from the winding drum or the sprocket 17 is guided via the fixed guide rollers, respectively the sprockets 23, 24 and the movable guide roller, respectively. a sprocket 25 with a weight 26 mounted in a guide at the bottom of the rail 1; a chain 18 guided via a guide pulley, respectively. the sprocket 27 at the end of rail 1 sleep to the other end of the carriage where it is anchored.

Vo východzej polohe vozíka je na kolajnicl 1 uchytená pevná konzola 28 s dorazom 29, ktorý má zakončeme.In the starting position of the carriage, a fixed bracket 28 with a stop 29 to be terminated is mounted on the rail 1.

Na základovej doske 4 vozíka je západka 30 vyčnievajúca před vozík smerom k pevnej konzole 28. Západka 30 je súčasťou dvojramennej páky výkyvné uloženej na základovej doske 4 a druhé rameno tejto páky cez otvor v základovej doske 4 zasahuje zo spodu pod rameno sklopnej narážky 3.On the base plate 4 of the trolley there is a latch 30 protruding in front of the trolley toward the fixed bracket 28. The latch 30 is part of a two-arm lever pivotally mounted on the base plate 4 and the second arm of this lever extends through the opening in the base plate 4.

Funkcia zariadenia spočívá v tom, že vozík nachádzajňci sa v svojej východzej polohe, pri pevnej konzole 28 má sklopnú narážku 3 sklopenú v žlabe prisúvacieho dopravníka 2. Kmeň pri pohybe po dopravníku 2 svojim čelom posúva sklopnú narážku 3 před sebou a prostredníctvom tejto aj vozík po kolajnici 1. S vozíkom sa posúva. aj lano, resp. reťaz 18 s lanom na jednom konci, ktorá je připevněná k vozíku z obidvoch stráň v smere jeho pohybu. Prostredníctvom lana, resp. reťaze 18 sa pri posuve vozíka otáča aj na ví jací bubon, resp. reťazové koleso 17 a pohonná jednotka 16, ktorá je vypnutá. Keď koniec kmeňa přejde miestom, kde je uložená narážka 19, vyšle táto impulz k zapnutiu pohonnej jednotky 16, ktorá prostredníctvom lana, resp. reťaze vyvíja, tah na vozík v smere protipohybu kmeňa. Pri sklopnej narážke 3 však excentér 21, ktorý je dntláčaný na kolajnici 1 pružinou, bráni spatnému pohybu vozíka. Možné je aj také riešenie, že medzi excentrom 21 a kolajnicou 1 je vola aj při sklopnej polohe sklopnej narážky 3 a excenter 21 sa do záběru s kolajnicou 1 uvedie ťahom lana 18 (napr. pootočením dvojramennej páky 10}, alebo elektromagnetom. Pri tomto převedení je možný obojsmerný pohyb vozíka aj pri sklopenej polohe sklopnej narážky 3.The function of the device is that the trolley in its initial position, with the fixed bracket 28, has a hinged stop 3 tilted in the trough of the feed conveyor 2. The trunk moves the hinged stop 3 in front of it by means of this and rails 1. It moves with the trolley. also rope, respectively. a chain 18 with a rope at one end which is attached to the trolley from both sides in the direction of its movement. Through the rope, respectively. When the carriage is moved, the chain 18 also rotates on the winding drum or the winding drum. a sprocket 17 and a drive unit 16 which is switched off. When the end of the trunk passes through the location where the cushion 19 is stored, it sends this impulse to turn on the drive unit 16, which by means of a rope or a cable, respectively. The chain develops, pulling on the trolley in the direction of the trunk counter movement. However, in the folding stop 3, the eccentric 21, which is pressed on the rail 1 by a spring, prevents the carriage from moving incorrectly. It is also possible for the eccentric 21 to be driven between the eccentric 21 and the rail 1 at the folding position of the hinge 3, and the eccentric 21 is brought into engagement with the rail 1 by pulling the rope 18 (eg by turning the two-arm lever 10) or by an electromagnet. a two-way movement of the truck is possible even when the folding stop 3 is folded down.

Ťahová sila v lané 18, ktorej je vedené cez pevné vodiace kladky 12, 13 a vodiacu kladku 11 uloženú na jednom ramene dvojramennej páky 10, pootočí dvojramennú páku 10, čím sa rameno s vodiacou kladkou 11 zdvihne smerom hoře a druhé rameno dvojramennej páky 10 s výsuvným kolíkem 9 sa pohybuje smerom dole. Výsuvný kolík 9, na ktorý posobí rameno sklopnej narážky 3 silou v smere pohybu kmeňa sa zasunie pod hornú stranu základovej došky 4 a sklopná narážka 3 sa pootočí okolo zvislého čapu v smere pohybu kmeňa a zároveň je ťahom v lané 18 dvíhaná do svojej hornej polohy, t. j. nad skosený výsuvný čap 7 na zvislej stene konzoly 5. Pri zdvíhaní sklopnej narážky 3 do hornej polohy je jej pohyb usměrňovaný vodiacou lištou 8, ktorá je v hornej časti tvarovaná tak, aby bránila pootáčaniu sklopnej narážky 3. Zdvíháním sklopnej narážky 3 lanom, resp. retazou 18 pri zastavenom vozíku sa predížuje spodná vetva lana, resp. reťaze 18. Toto predlženie je eliminované pohybom pohyblivej kladky, resp. reťazového kolesa 25 so závažím 26 smerom dole, takže lano, resp. reťaz 18 ostává stále napnuté.The tensile force in the rope 18, which is guided through the fixed guide pulleys 12, 13 and the guide pulley 11 mounted on one arm of the two-arm lever 10, rotates the two-arm lever 10, thereby raising the arm with the guide pulley 11 upwards and the other arm of the two-arm lever 10 s the pull-out pin 9 moves downwards. The extension pin 9, on which the arm of the hinge 3 is pushed by force in the direction of trunk movement, is inserted under the upper side of the foundation thatch 4 and the hinge 3 rotates around the vertical pivot in the direction of trunk movement. t. j. above the bevelled extension pin 7 on the vertical wall of the bracket 5. When raising the hinged stop 3 to its upper position, its movement is guided by a guide bar 8, which is shaped at the top so as to prevent the hinged stop 3 from rotating. With the chain 18 when the trolley is stopped, the lower strand of the rope is extended. This elongation is eliminated by the movement of the movable pulley, respectively. of the sprocket 25 with a weight 26 downwards, chain 18 remains tensioned.

Pri příchode sklopnej narážky 3 do hornej polohy pootočí táto dvojramennou pákou 22, ktorá pootočí exentrom 21 tak, že sa tento zdvihne nad kolajnicu 1, čím sa vozík odbrzdí a pohybuje sa do východzej polohy k pevnej konzole 28. Před príchodom vozíka k pevnej konzole 28 sa posobením vozíka na spínač 20 vypne pohonná jednotka a vozík zotrvačnosťou dojde k pevnej konzole 28,. o ktorú sa uzamkne západkou 30 proti spatnému odrazeniu. Dojazd vozíka k pevnej konzole 28 je tlmený dorazom 29, ktorý má pružné zakončeme, Doraz 29 pri dojazde vozíka k pevnej konzole 23 zatlačí pružným koncom jedno rameno dvojramennej páky so skoseným výsuvným čapom 7, ktorá je umiestnená na zvislej stene konzoly 5. Skosený výsuvný čap sa zasunie, čím sa odistí pohyb sklopnej narážky 3 do sklopenej polohy a zároveň sa zapnú reverzně otáčky pohonnej jednotky 16, ktorá zdvihne pohyblivú vodiacu kladku, resp. reťazové koleso 25 so závažím 2S do takej výšky, aby sa sklopná narážka 3 sklopila do žlabu dopravníka 2 vlastnou váhou. Potom sa reverzně otáčky pohonnej jednotky vypnú. Pád sklopnej narážky 3 je tlmený závažím, resp. pružinou 26. Po sklopení sklopnej narážky 3 zatlačí táto kolík, ktorý vyčnieva zo spodnej strany základovej došky 4 a ktorý je upevněný na opačnom ramene tej istsj dvojramennej páky ako západka 30, pričom sa západka 30 zdvihne a odistí pohyb vozíka v smere pohybu kmeňa. Zariadenie je připravené na meranie dlžky ďalšieho kmeňa, resp. výřezu.Upon arrival of the hinged stop 3 to the upper position, it rotates the two-arm lever 22, which rotates the eccentric 21 so that it is lifted above the rail 1, thereby releasing the carriage and moving to the fixed position 28 before the carriage arrives. by powering the carriage to the switch 20, the drive unit is switched off and the carriage inertia leads to a fixed bracket 28. by which it is locked by a latch 30 against false reflection. The approach of the trolley to the fixed bracket 28 is damped by a stop 29 having a resilient end. When the trolley reaches the fixed bracket 23, the stopper 29 pushes one arm of a double-arm lever with a bevelled slide 7 is retracted, thereby releasing the movement of the hinged stop 3 to the stowed position and at the same time reversing the revolutions of the drive unit 16, which lifts the movable idler pulley or the pulley. a sprocket 25 with a weight 2S to a height such that the folding stop 3 is lowered into the conveyor trough 2 by its own weight. Then the reverse drive speed is switched off. The fall of the hinge 3 is damped by the weight, respectively. When the folding stop 3 is lowered, it pushes the pin which protrudes from the underside of the base that is fixed to the opposite arm of the two-arm lever as the pawl 30, the pawl 30 raising and unlocking the carriage movement in the direction of trunk movement. The device is ready to measure the length of another strain, respectively. viewport.

Ďalší příklad činnosti, resp. prevedenia vyššie popísaného zariadenia je taký, že sklopná narážka 3 je v svojej sklopenej polohe dotláčaná napr. pružinou smerom ku konzole 5, teda smerom k čelu kmeňa. Vychýlením sklopnej narážky 3 čelom kmeňa k výsuvnému kolíku 9, resp. k inému dorazu na jeho úrovni sa zapne elektrický spínač, ktorý zapne pohonnú jednotku 16 a vozík sa odsunie od čela kmeňa. Sklopná narážka 3 sa vrátí ku konzole 5 a vypínač sa znovu vypne pohonnú jednotku 16, ktorou by pre tento příklad bol najvhodnejší krokový motor. Po ukončení merania dlžky može pohonná jednotka 16 dostat impulz, aby na určitej dížke dráhy vozíka, resp. v určitom časovom intervale zvychýleným pohybem posunula vozík v smere pohybu kmeňa, čím by vozík kmeň pradbehol a až po tomto dížkovom, resp. časovom úseku by sa zapli reverzně otáčky pohonnej jednotky 16, čiže zdvíbanie klopnej narážky 3 a spatný pohyb vozíka do východzej polohy. Pri tomto režime činnosti zariadenia nie je nutné, aby sklopná narážka 3 bola na základovej doske 4 otočné uložená a na mieste výsuvného kolíka 9 méže byt pevný doraz.Another example of action, respectively. An embodiment of the device described above is such that the hinged stop 3 is pressed in its hinged position e.g. spring towards the console 5, i.e. towards the trunk face. By tilting the hinged stop 3 with the trunk face toward the pull-out pin 9, respectively. to another stop at its level, an electric switch is switched on that turns on the drive unit 16 and the carriage is moved away from the trunk face. The hinged stop 3 returns to the bracket 5 and the switch switches off the drive unit 16 again, which would be the most suitable stepper motor for this example. Upon completion of the length measurement, the drive unit 16 may be given an impulse so that, at a certain length of the carriage path, respectively. within a certain period of time with an accelerated movement, it moved the trolley in the direction of movement of the trunk. for a period of time, the revolutions of the drive unit 16, i.e. the raising of the tilting stop 3 and the wrong movement of the truck to the starting position, would be switched on. In this mode of operation of the device, it is not necessary that the hinged stop 3 is rotatably mounted on the base plate 4 and a fixed stop can be provided in place of the pull-out pin 9.

V případe, že pohyb a velkost posunutia kmeňa na dopravníku 2 třeba sledovat v obidvoch smeroch, napr. v níektorých prípadoch pri nameriavaní dlžky výrezov, možno to popísaným zariadením urobit tak, že převedeme zariadenia by bolo ako v predchádzajúcom případe, ale elektrický spínač ovládaný sklopnou narážkou 3 by bol na základovej doske 4 na straně konzoly 5 a v případe, že by tento bol počas merania dlžky zapnutý, t. j. ked' čelo kmeňa netlačí na sklopná narážku 3, pohonná jednotka tahá vozík smerom k čelu kmeňa, t. j. proti pohybu kmeňa. Po dotlačení sklopnej narážky 4 čelom kmeňa k výsuvnému kolíku 9, respektive dorazom na jeho úrovni vypne elektrický vypínač pohonnú jednotku 16 a vozík je tlačený kmeňom.In the case that the movement and the displacement amount of the trunk on the conveyor 2 need to be monitored in both directions, e.g. in some cases, when measuring the length of the slots, this can be done by transferring the device as in the previous case, but the electric switch operated by the hinged stop 3 would be on the base plate 4 on the side of the bracket 5 and length measurement on, t. j. when the trunk face does not press on the folding stop 3, the drive unit pulls the trolley towards the trunk face, t. j. against the movement of the trunk. After pushing the folding stop 4 towards the pull-out pin 9 or the stop at its level, the electric switch switches off the drive unit 16 and the trolley is pushed by the log.

256720 protrudes from the bottom side of the base plate 4 and which is fixed to the opposite shoulder of the two-arm lever as a pawl 30, wherein the pawl 30 is raised and unlocks the movement of the carriage in the direction of movement of the stem. measuring the next strain, respectively. cutout. Another example of activity, respectively. The device described above is such that the hinged stop 3 is pressed in its tilted position by, for example, a spring towards the console 5, i.e. towards the front of the stem. By deflecting the hinge stop 3 by the head end to the extendable pin 9, respectively. The electric switch is switched on at its level, which switches on the drive unit 16 and the vehicle moves away from the front of the trunk. The collapsible stop 3 returns to the bracket 5 and the switch shuts off the drive unit 16, which for this example is the most suitable stepping motor. Upon completion of the measurement of the length, the drive unit 16 can be pulsed to a certain length of the carriage path, respectively. in a certain time interval, the carriage moved in the direction of movement of the trunk in an angular motion, whereby the trolley would run through and then the trolley or trolley. the time slot would reverse the speed of the drive unit 16, that is, the raising of the tilting stop 3 and the poor movement of the carriage to the initial position. In this mode of operation of the device, it is not necessary for the tilting stop 3 to be rotatably mounted on the base plate 4 and a stop can be fixed at the location of the withdrawable pin 9. In the event that the movement and size of the shifter on the conveyor 2 need to be observed in two directions, e.g. in some cases when measuring the length of the cuts, the device described can be made to transfer the device as in the previous case, but the electric switch controlled by the hinged stop 3 would be on the base plate 4 on the sulfur console 5, and if this would be switched on during the length measurement, ie when the stem front does not push the stop 3, the drive unit pulls the tow bar towards the stem face , ie, against strain movement. After pushing the hinge stop 4 against the stem 9 to the retractable pin 9, the resistor stops at its level, the electric switch switches off the drive unit 16 and the carriage is pushed by the trunk. The construction of the device for measuring the stamens according to the present invention allows for a very precise measurement of the length of the stem or cut at relatively small production costs.
