Postopek za pripravo svinčenih akumulatorskih plošč za formiranje in priprava za čiščenje ploščnih ušescProcedure for the preparation of lead-acid battery plates for forming and for preparing the eyelet

Izum spada v področje elektrotehnike, nanaša pa se na pripravo svinčenih akumulatorskih plošč za formiranje s pomočjo premazovanja in sušenja plošč, čiščenja njihovih ušesc in ločevanje dvojnih rešetk. Izum se prav tako nanaša na pripravo za čiščenje ušesc.The invention relates to the field of electrical engineering, and relates to the preparation of lead-acid battery plates for forming by coating and drying the plates, cleaning their ears and separating the double bars. The invention also relates to a device for cleaning the ears.

Tehnični problem, ki ga rešuje predloženi izum, je v tem, kako določiti postopek za pripravo svinčenih akumulatorskih plošč za formiranje in tako konstrukcijsko rešiti pripravo za čiščenje ušesc na ploščah, s katerima bi se omogočilo zmanjšanje število operacij med pripravo za formiranje svinčevih akumulatorjev ob hkratnem bistvenem zmanjšanju poškodovanja in izgub paste zaradi mehaničnih obremenitev med manipulacijami z rešetko in ploščami in s katerima bi se nadalje omogočila enostavnejša in zaneslivejša izdelava.A technical problem solved by the present invention is how to determine the procedure for preparing lead-acid battery plates for forming, and thus to constructively resolve the device for cleaning the eyelets on the plates, which would allow to reduce the number of operations during preparation for the formation of lead-acid batteries at the same time substantially reducing the damage and loss of the paste due to mechanical stresses during the grate and plate manipulations, which would further allow for simpler and more reliable manufacturing.

Znano je da se pri izdelavi svinčevih akumulatorjev najprej premažejo dvojne rešetke z aktivnim materialom in se zatem premazane plošče sušijo v raznih pripravah za sušenje, ki so poznane na tem področju. Po sušenju plošč se le-te vnašajo v priprave za čiščenje in snemanje po sinhroniziranih operacijah, kjer se odstranjuje aktiven material z neustreznih mest, dvojne plošče pa se razločujejo, to se pravi, lomijo.It is known that in the manufacture of lead-acid batteries, the double grilles are first coated with the active material and then the coated plates are dried in various drying preparations known in the art. After drying the plates, they are introduced into the devices for cleaning and recording after synchronized operations, where the active material is removed from the inappropriate places and the double plates are distinguished, that is, broken.

V zgoraj opisanih operacijah se dvojne rešetke mehanično dostavljajo v potrebne delovne položaje s prijemom ušesc 5, ki se nahajajo na dvojnih rešetkah 14, ki so prikazane na sl. 1. V skladu s tem je končna operacija ločevanje dvojnih rešetk oz. njihovo lomljenje na posamezne plošče.In the operations described above, the double grilles are mechanically delivered to the required working positions by gripping the ears 5 located on the double grilles 14 shown in FIG. 1. Accordingly, the final operation is the separation of the double lattices, respectively. their breaking into individual panels.

Ta izdelovalni postopek, ki je na splošno poznan in ki se izkorišča v tem postopku, ima nekoliko resnih pomanjkljivosti. Ločevanje dvojnih plošč namreč zahteva posebno enoto, takoimenovani sinhronizator, predpripravo za čiščenje in ločevanje, pri Čemer se razločevanje, to se pravi lomljenje dvojnih plošč 14 vrši, vsaj teoretično po geometrijski osi 2 takoimenovanih muljnih nožič 3 dvojnih plošč. Izreza 4 muljnih nožič se med premazovanjem zapolnjujeta s pasto, ki se uporablja v običajnem postopku. Pasta, ki se je med premazovanjem prilepila na ušesci 5, se mora ob čiščenju ušesc odstraniti.This manufacturing process, which is generally known and utilized in this process, has some serious drawbacks. The separation of double plates requires a special unit, the so-called synchronizer, a pre-treatment for cleaning and separation, whereby differentiation, that is, breaking of the double plates 14, is carried out, at least theoretically along the geometric axis 2 of the so-called sludge blades 3 of the double plates. The cutouts of the 4 sludge blades are filled with the paste used in the normal process during coating. The paste adhered to the eyelet 5 during the coating must be removed when cleaning the eyelets.

Obstojijo pa različne vrste defektov, ki se pojavljajo pri delovanju sinhronizacijske enote, tako da lahko do lomljenja dvojnih plošč pride tudi izven osi 2, zaradi izmikanja pa se plošče lahko neznatno deformirajo, lahko pa pride tudi do odstopanja muljnih nožič 3 od ravnine, v kateri se nahajajo plošče. Njihovi negativni učinki se lahko pojavljajo med sestavljanjem akumulatorja, pri čemer se zmanjšuje učinkovitost postopka izdelave. Te pomanjkljivosti mehaničnega značaja se dopolnjujejo z visoko obremenitvijo, do katere prihaja med razločevanjem in zaradi odpadanja aktivnega materiala ter delcev svinca zaradi velike hitrosti ščetk za čiščenje v čistilniku, kar ne onesnažuje le priprave temveč tudi in predvsem okolico na resen in nevaren način.However, there are different types of defects that occur during the operation of the synchronization unit, so that the breaking of the double plates can occur even outside the axis 2, and due to the displacement, the plates may be slightly deformed and the sludge blades 3 may deviate from the plane in which there are panels. Their negative effects can occur during assembly of the battery, thus reducing the efficiency of the fabrication process. These deficiencies of mechanical character are compounded by the high load that arises during the separation and the depletion of the active material and lead particles due to the high speed of the cleaning brushes in the scrubber, which not only contaminates the preparation but also, and especially the environment, in a serious and dangerous way.

Zaradi navedenih razlogov so defekti pri sinhronizaciji enot za čiščenje in razločevanje dvojnih plošč zelo pogosti, njihovo delovanje pa zahteva neprekinjeno in pozorno nadzorovanje.For these reasons, defects in the synchronization of double-panel cleaning and differentiation units are very common, and their operation requires continuous and careful monitoring.

Naloga izuma je, da se razdela postopek in priprava, s katerima bi se omogočilo zmanjšanje števila operacij med pripravo za formiranje svinčevih akumulatorjev ob hkratno bistvenem zmanjšanju poškodb in izgub v pasti zaradi mehaničnih obremenitev med manipulacijami z rešetko in ploščami in s katerima bi nadalje bila omogočena enostavnejša in zaneslivejša izdelava.It is an object of the invention to separate a process and apparatus that would allow the reduction of the number of operations during preparation for the formation of lead accumulators while significantly reducing the damage and losses in the trap due to mechanical loads during the manipulation of the grid and plates and which would further enable simpler and more reliable manufacturing.

Izum je zasnovan na spoznanju, da se navedeni cilj lahko doseže in da se sinhronizacija (pozicioniranje) lahko izogne, če se dvojne rešetke razločujejo neposredno pred premazovanjem, to se pravi plošče se premazujejo samo po razločevanju dvojnih plošč, ušesca pa se čistijo neposredno po sušenju.The invention is based on the realization that the stated goal can be achieved and that synchronization (positioning) can be avoided if the double bars are distinguished immediately before coating, that is, the plates are coated only after the double plates are distinguished and the ears are cleaned immediately after drying. .

Nadaljnja osnova izuma je v spoznanju, da se aktiven material, ki se lepi na ušesca plošč, ki se razločujejo pred premazovanjem, lahko dobro in ekonomično sname s posebno pripravo in tako odpravi pomanjkljivost nemožnosti dovajanja plošč s prijemanjem za njihova ušesca, pri čemer pa se ta postopek v glavnem izkorišča z običajno opremo.A further basis of the invention is in the knowledge that the active material that adheres to the ears of the panels that differ before coating can be removed well and economically by a special device, thus eliminating the disadvantage of not being able to feed the plates by gripping their ears, it mainly utilizes this process with conventional equipment.

Na osnovi navedenega se izum nanaša na postopek za pripravo svinčenih akumulatorskih plošč za formiranje s premazovanjem, sušenjem plošč, čiščenjem ušesc po premazovanju in sušenju plošč, pri čemer se eliminira postopek sinhronizacije.Based on the foregoing, the invention relates to a process for the preparation of lead-acid battery plates for forming by coating, drying plates, cleaning the ears after coating and drying the plates, eliminating the synchronization process.

Priprava je opremljena s pogonom, s transportnima stezama, nosilnima stezama in s ščetkami. Priprava je značilna po tem, da se sestoji iz vodoravno razporejenih vzporednih spodnjih nosilnih plošč 15 in zgornjih nosilnih plošč 15a, ki se nahajajo na spremenljivi razdalji, spodnjih togih stez 12 in zgornjih elastičnih transportnih stez 16, ki se nahajajo med nosilnima ploščama in 15a, vendar v ravninah, ki sta vzporedni z njima, na spremenljivi oddaljenosti, togih nosilnih stez 19, ki se nahajajo v isti ravnini kot spodnje transportne steze v eni polovici priprave, vendar z zgornjimi transportnimi stezami 16 v drugi polovici priprave, pri čemer so zgornje elastične transportne steze 16 ločene z elastičnimi nosilnimi okviri 21 od zgornje nosilne plošče 15a, pri čemer so transportne steze 12 in in toge nosilne plošče 19 sinhronizirano poganjane, in da priprava nadalje obstoji iz ščet 13 za čiščenje, ki omejujejo spodnjo togo transportno stezo 12 in zgornjo elastično transportno stezo 16 z leve in desne strani, pri čemer so elastični nosilci 21 pritijeni v eni polovici priprave za spodnjo nosilno ploščo 15, v drugi polovici pa za zgornjo nosilno ploščo 15a, pri čemer so elastični nosilci 21, ki so pritrjeni na spodnjo nosilno ploščo 15, nameščeni pod povezanimi ščetkami 13, medtem ko so elastični nosilci, ki so pritrjeni na zgornjo nosilno ploščo 15, nameščeni nad povezanimi ščetkami 13, in pri čemer so toge nosilne steze 19 nameščene v tisti polovici priprave, v kateri so elastični nosilci 21 pritrjeni na spodnji nosilni plošči 15 nad ščetkami 13, medtem ko so v drugi polovici priprave nameščeni pod ščetkami 13.The invention further relates to a device for cleaning the ears of lead-acid battery panels. A schematic drawing is shown in FIG. 2a and 2b. The machine is equipped with a drive, conveyor belts, carrier lanes and brushes. The device is characterized in that it consists of horizontally spaced parallel lower support plates 15 and upper support plates 15a located at a variable distance, lower rigid lanes 12 and upper elastic transport lanes 16 located between the carrier plates and 15a, however, in planes parallel to them at a variable distance, rigid support lanes 19 located in the same plane as the lower conveyor lanes in one half of the device, but with the upper conveyor lanes 16 in the other half of the device, with the upper elastic ones conveyors 16 separated by resilient carrier frames 21 from the upper carrier plate 15a, the conveyor tracks 12 and and the rigid carrier plates 19 being synchronously driven, and the apparatus further comprising cleaning brushes 13, which restrict the lower rigid conveyor belt 12 and the upper an elastic conveyor belt 16 on the left and right sides, wherein the elastic carriers 21 are fastened to one half of the device for the lower carrier plate 15 and the other half for the upper carrier plate 15a, wherein the elastic carriers 21 which are attached to the lower carrier plate 15 are positioned under connected brushes 13 while the elastic carriers which are attached to the upper support plate 15 mounted above the connected brushes 13 and the rigid carrier tracks 19 are arranged in that half of the device in which the elastic carriers 21 are attached to the lower carrier plate 15 above the brushes 13 while being mounted in the second half of the device under the brushes 13.

V primeru izvedbenega primera priprave po izumu, ki se priporoča, so ščetke 13 in nosilne steze 19, ki ustrezajo tem ščetkam 13, izdelane samo v eni polovici priprave.In the case of the embodiment of the device according to the invention which is recommended, the brushes 13 and the supporting lanes 19 corresponding to these brushes 13 are made in only one half of the device.

Izvajanje postopka po izumu, ki se priporoča, je podrobno opisano s sklicevanjem na priložene slike.The implementation of the process according to the invention which is recommended is described in detail with reference to the accompanying drawings.

Slika 1 prikazuje dvojno rešetko.Figure 1 shows a double grid.

Sliki 2/a in 2/b prikazujeta shemo priprave za čiščenje ušesc, ki je pritrjena na sušilnik.Figures 2 / a and 2 / b show the scheme of the ear cleaning device attached to the dryer.

Slika 3 prikazuje izgled priprave na sliki 2 s spodnje strani.Figure 3 shows the layout of the device in Figure 2 from the bottom.

Priprava po izumu ima vodoravno konfiguracijo, pri čemer se razdalja med njegovimi vzporedno nameščenimi spodnjimi osnovnimi ploščami 15 in zgornjimi nosilnimi ploščami 15a lahko spreminja. Prav tako se lahko spreminja razdalja med spodnjo togo transportno stezo 12 in zgornjo elastično transportno stezo 16, ki sta nameščeni med nosilnimi ploščami v vzporednih ravninah druga nad drugo. Elastične zgornje transportne steze 16 so ločene od zgornje nosilne plošče 15a s pomočjo nosilnih konstrukcij 21. Transportne steze 12 in 16 imajo sinhronizirani pogon, to se pravi njihove hitrosti dostavljanja so identične.The device according to the invention has a horizontal configuration, and the distance between its parallel base plates 15 and the upper carrier plates 15a can be varied. Also, the distance between the lower rigid conveyor 12 and the upper elastic conveyor 16 arranged between the support plates in parallel planes may be varied above each other. The elastic upper conveyor lanes 16 are separated from the upper carrier plate 15a by means of load-bearing structures 21. The conveyor lanes 12 and 16 have a synchronous drive, i.e. their delivery rates are identical.

Toge nosilne plošče 16 se nahajajo v isti ravnini kot spodnja toga transportna steza v isti polovici priprave, pri čemer pa je zgornja elastična transportna steza 16 v drugi polovici priprave. Transportne steze 12 in 16 so lahko izvedene bodisi v obliki verige bodisi v obliki traku.The rigid carrier plates 16 are located in the same plane as the lower rigid conveyor belt in the same half of the device, with the upper elastic conveyor belt 16 in the second half of the device. Transport lanes 12 and 16 may be made either in the form of a chain or in the form of a belt.

Ščetke 13 za čiščenje so povezane v eni polovici priprave s spodnjo nosilno ploščo 15, v drugi polovici priprave pa z zgornjo nosilno ploščo 15a preko elastičnih nosilcev 21.The cleaning brushes 13 are connected in one half of the device with the lower carrier plate 15 and in the other half of the preparation with the upper carrier plate 15a via elastic carriers 21.

Ščetke so lahko izdelane bodisi iz kovine bodisi iz umetnih vlaken. Spodnja toga transportna steza 12 in zgornja elastična steza 16 sta z obeh strani omejeni s ščetkami 13.Brushes can be made of either metal or man-made fibers. The lower rigid conveyor lane 12 and the upper elastic lane 16 are bounded on each side by brushes 13.

V tisti polovici priprave, v kateri so elastični nosilci 21 pritijeni na spodnjo nosilno ploščo 15, se toge nosilne steze 19 nahajajo nad ščetkami 13, medtem ko se v drugi polovici priprave toge nosilne steze nahajajo pod ščetkami 13.In that half of the device in which the elastic beams 21 are attached to the lower carrier plate 15, the rigid carrier strips 19 are located above the brushes 13, while in the second half of the rigid carrier strips arrangement they are located below the brushes 13.

Vsak transportni element priprave za čiščenje ušesc se lahko poganja s pomočjo centralnega pogona z zvezno spremenljivo hitrostjo.Each conveyor element of the ear cleaning device can be driven by a variable speed centralized drive.

Na slikah so izpuščene tiste enote, ki so zelo pomembne za delovanje, npr. stikala, motoiji, pogoni, zbiralniki odpadkov in podobno, ki pa niso nujne za razumevanje izuma, bi pa zapletale razumevanje izuma.The pictures omit those units that are very important for operation, e.g. switches, motoes, actuators, waste collectors and the like, which are not essential for understanding the invention but would complicate the understanding of the invention.

Priprava za čiščenje ušesc deluje na naslednji način. Dve plošči 14 se ločeno odvzemata s stezama 12 in 16 po njunem ločevanju v separatoiju in se nato dostavljata z isto hitrostjo. Vsaka plošča se dostavlja s pomočjo dveh parov transportnih stez 12 in 16. Ušesci 5 plošč 14 se naslanjata na po eno togo nosilno stezo 19, v sprednjem vhodnem delu priprave pod (slika 2a), v izstopnem delu pa nad njo (slika 2b). V teku dostavljanja plošč se ušesca 5 gibajo najprej pod ščetkami 13, kot je prikazano na sliki 2a, zatem pa prihajajoč naprej v drugi del priprave, kar je prikazano na sliki 2b, nad ščetkami 13, tako da se aktiven material, ki se je prilepil na obe strani ušesc 5 snema s ščetkami 13. Odstranjeni aktivni material pada v zaprti zbiralnik, ki na sliki 2 ni prikazan.The ear cleaning device works as follows. The two plates 14 are separated separately from lanes 12 and 16 after their separation in the separatio and then delivered at the same speed. Each panel is delivered by means of two pairs of transport lanes 12 and 16. The lugs 5 of the panels 14 rest on one rigid carrier lane 19, in the front inlet of the device below (Fig. 2a) and in the outlet portion above it (Fig. 2b). During the delivery of the plates, the lugs 5 move first under the brushes 13, as shown in Fig. 2a, and then coming forward into the second portion of the preparation, as shown in Fig. 2b, above the brushes 13, so that the active material adhered on both sides of the ears 5 is removed by brushes 13. The removed active material falls into the closed reservoir, which is not shown in Figure 2.
