Description

Predloženi izum se nanaša na napravo za avtomatično razdeljevanje proizvodov (končnih ali polizdelanih) od zbirnega mesta k nadaljnjim mestom obdelave. Razdeljevanje poteka tako, da krožnik ali posoda, kjer so zbrani proizvodi, začne vibrirati, tako da le-ti izstopijo iz samega krožnika in krenejo po določenih vodilnih linijah k omenjenim mestom obdelave.The present invention relates to a device for the automatic distribution of products (finished or semi-finished) from a collection point to further processing points. The distribution is carried out in such a way that the plate or container where the products are collected begins to vibrate so that they exit from the plate itself and proceed along specified guide lines to the points of treatment mentioned.

Posebno prednost med takšnimi pripravami ima konfiguracija, pri kateri je predvidena osnovna plošča, na kateri je s pomočjo listnato-vzmetne obese pritrjen vibrirajoči krožnik.A particular advantage of such arrangements is the configuration in which the base plate is provided, on which a vibrating plate is attached by means of a leaf-spring suspension.

Pri znani tehniki so listnate vzmeti položene na v bistvu vertikalnih ravneh in pritrjene na opore na osnovni plošči s pomočjo vijakov privitih v luknje, ki so pravokotne na ravnine listov, ki tvorijo samo listnato vzmet.In the prior art, the leaf springs are arranged at substantially vertical levels and secured to the supports on the base plate by means of screws screwed into holes perpendicular to the plane of the leaves forming only the leaf spring.

Takšna naprava ima zelo enostavno konstrukcijo, vendar pa izkazuje tudi pomanjkljivosti, ki jih ni mogoče zanemariti. Tako, med obratovanjem dodajalnika, v posebnih pogojih obratovanja, listnata vzmet lahko prenese na pritrdilni vijak znatne upogibne obremenitve. Ker pa vijak po svoji strukturi ne more prenesti visokih upogibnih obremenitev, prihaja pogostokrat do lomov prav v zvezi s pritrdilnimi sredstvi listnatih vzmeti.Such a device has a very simple construction, but also shows defects that cannot be neglected. Thus, during the operation of the feeder, under special operating conditions, the leaf spring can transfer considerable flexural load to the retaining screw. However, since the bolt cannot withstand high bending loads in its structure, it is often the case that fractures occur precisely in connection with the mounting means of leaf springs.

Poleg tega, ker sam pritrdilni vijak obenem izvede tudi paketiranje listov listnate vzmeti, je jasno, da mora biti delovni postopek vložitve in pritrditve vijaka izveden s posebno natančnostjo.In addition, since the fastening screw itself also packs the leaf of the leaf spring, it is clear that the working process of inserting and fixing the screw must be carried out with particular precision.

Splošni cilj predloženega izuma je, izogniti se zgoraj omenjenim pomanjkljivostim s tem, da nudi pritrdilno spono za listnato-vzmetno obeso pri vibracijskih napravah, pri katerih sredstva za pritrditev listnate vzmeti omogočajo primerno odpornost tudi pri visokih upogibnih obremenitvah.The general object of the present invention is to avoid the aforementioned disadvantages by providing a leaf clamp for leaf-spring suspension in vibrating devices, in which the means for fixing leaf-springs provide adequate resistance even at high bending loads.

Dodaten cilj izuma je, da le-ta nudi pritrdilno spono za listnato-vzmetno obeso, pri kateri sta privijanje paketa listov, ki oblikujejo listnato vzmet, in popolna pritrditev na osnovno ploščo izvedena ločeno.An additional object of the invention is that it provides a fastener for the leaf-spring suspension, in which the packing of the leaf-forming leaves of the leaf spring and the complete attachment to the base plate are made separately.

Glede na takšne cilje, smo se v skladu z izumom namenili izdelati pritrditev za listnato- vzmetno obeso na osnovno ploščo vibracijske naprave, ki je označena s tem, da obsega zatični vijak, ki sega iz fiksne opore pritrjene na osnovno ploščo, s koncem, ki sega v premično oporo in gre s svojim srednjim delom pravokotno skozi listnato vzmet, pritrdilna sredstva, ki v sodelovanju z zatičnim vijakom privijejo premično oporo in listnato vzmet k fiksni opori in pritrdilna sredstva predvidena za pritrditev premične opore na osnovno ploščo na odstranljivi način.In view of such objectives, it is an object of the invention to provide a leaf-spring suspension mounting to a vibration device base plate, characterized in that it comprises a bolt extending from a fixed support attached to the base plate with an end that extends into the movable support and extends perpendicularly through the leaf spring through its middle part, fastening means which, in conjunction with the bolt, screw the movable support and leaf spring to the fixed support, and the fastening means provided for attaching the movable support to the base plate in a removable manner.

Poleg tega smo izvedli vibracijsko napravo opremljeno z listnato-vzmetno obeso pritrjeno v skladu z izumom.In addition, a vibration device equipped with a leaf-spring suspension attached in accordance with the invention was implemented.

Za jasnejšo razlago inovacijskih principov predloženega izuma in njegovih prednosti glede na že znano tehniko, bomo v nadaljevanju opisali s pomočjo priloženih risb primer ene od možnih izvedb, ki aplicirajo takšne principe.In order to provide a clearer interpretation of the innovation principles of the present invention and its advantages in the light of the prior art, we will hereinafter describe, by way of the accompanying drawings, an example of one of the possible embodiments applying such principles.

S. 2 prikazuje v tlorisu povečani detajl naprave za pritrditev listnate vzmeti v skladu z izumom, pogled z ravnine ll-ll iz slike 1.S. 2 is an enlarged detail of a plan view of a leaf spring mounting device according to the invention, a plan view 11b-ll of Figure 1.

Sl. 3 prikazuje izgled vzdolž prereza lll-lll iz slike 2.FIG. 3 shows the layout along the section lll-lll of Figure 2.

Nanašajoč se na sl. 1 vidimo, da shematsko prikazuje napravo 10 za avtomatsko vibracijsko razdeljevanje proizvodov proti nadaljnim obdelovalnim mestom ali skladiščenju.Referring to FIG. 1 shows a schematic representation of a device 10 for automatically vibrating the distribution of products against further processing sites or storage.

Naprava 10 obsega vibrirajoči krožnik ali posodo 11, v kateri se zbirajo proizvodi za razdeljevanje in ki je povezana s fiksno osnovno ploščo 13 s pomočjo vzmetne obese 12.The apparatus 10 comprises a vibrating plate or container 11 in which the products for distribution are collected and connected to the fixed base plate 13 by means of a suspension bracket 12.

Listnate vzmeti 12 so razporejene na v bistvu vertikalnih ravneh in so pritrjene na osnovno ploščo 13 in na krožnik 11 z zatičnimi vijaki ali vložki z navojem 14, 15, ki jih privijemo v opore 16 oziroma 17 pravokotno na same listnate vzmeti.The leaf springs 12 are arranged at substantially vertical levels and are fixed to the base plate 13 and to the plate 11 by means of screws or threaded inserts 14, 15, which are screwed into the supports 16 and 17 respectively perpendicularly to the leaf springs themselves.

Kot vidimo na slikah 2 in 3, ki detajlno prikazujeta pritrditev listnate vzmeti 12 na osnovno ploščo 13, je vložek z navojem 14 speljan s srednjim delom svojega stebla skozi luknjo 18 v listih vzmeti in se privije na enem svojem koncu v luknjo z navojem 19 opore 16, ki je del osnovne plošče. Na drugem koncu gre vložek 14 skozi luknjo 20 premične kovinske opore 21. Na ta zadnji konec vložka z navojem 14 je privita matica 22 za privijanje premične opore in liste vzmeti k fiksni opori 16.As seen in Figures 2 and 3, which detail the attachment of the leaf spring 12 to the base plate 13, the threaded insert 14 is guided by the middle part of its stem through the hole 18 in the leaf springs and screwed at one end of it to the threaded hole 19 of the support 16, which is part of the baseplate. At the other end, the insert 14 passes through the hole 20 of the movable metal support 21. At this rear end of the insert with thread 14 there is a screw 22 for fastening the movable support and the spring leaves to the fixed support 16.

Predvidena je še druga izvrtina 23, ki sega skozi premično oporo 21, za vložitev vijaka 24 za pritrditev same opore, ki je nameščena pravokotno na vložek 14 na v bistvu vertikalni ravnini, na osnovno ploščo 13.A second bore 23 extending through the movable support 21 is provided for inserting a screw 24 for securing the support itself, which is perpendicular to the insert 14 on the substantially vertical plane, to the base plate 13.

Za montažo obese privijemo prvi konec vložka z navojem 14 v fiksno oporo 16, nato pa nastavimo listnato vzmet 12 proti tej opori tako, da centriramo luknjo 18 na navzven segajoči zatični vijak 14, nato pa postavimo premično oporo 21, da zapremo listnato vzmet na sandvvich-način. Nazadnje privijemo matico 22 na prosti konec vložka 14 in jo pritegnemo tako, da dosežemo želeno stopnjo paketiranja listov listnate vzmeti. Na tej točki pritrdimo premično oporo 21 na osnovno ploščo 13 z vijakom 24. Prednostno ima luknja 23 v smeri vložka 14 večjo dimenzijo kot premer vijaka 24, tako da omogočimo kompenzacijo eventuelnih položajnih sprememb premične opore, ki bi lahko nastopite zaradi različnih obremenitev pri pritegovanju matice 22.For mounting the suspension, screw the first end of the threaded insert 14 into the fixed support 16, then adjust the leaf spring 12 against this support by centering the hole 18 on the outwardly-securing pin 14, and then install the movable support 21 to close the leaf spring on the sandwich way. Finally, tighten the nut 22 to the free end of the insert 14 and tighten it to achieve the desired packing rate of the leaf spring springs. At this point, attach the movable support 21 to the base plate 13 with the screw 24. Preferably, the hole 23 in the direction of the insert 14 has a larger dimension than the diameter of the screw 24, so as to compensate for any positional changes in the movable support that could occur due to different loads when tightening the nut. 22.

V skladu z izumom je jasno, da je vložek z navojem 14 izpostavljen v glavnem strižnemu delovanju, proti kateremu pa je po svoji strukturi dobro odporen, medtem ko kovinska opora 21 prenese upogibne obremenitve. Zato so v bistvu odpravljeni vzroki za lom pritrdilnega elementa vzmeti, ki so tipični za naprave izdelane po znani tehniki.According to the invention, it is clear that the threaded insert 14 is exposed in the main shear action, but is well resilient in its structure, while the metal support 21 can withstand bending loads. Therefore, the causes of fracture of the spring fastener, which are typical for devices manufactured by known techniques, are essentially eliminated.

Poleg tega stopnjo privijanja paketa listov, ki tvorijo vzmet, ne spreminjamo v primeru, ko moramo zaradi kateregakoli vzroka popustiti pritrdilni vijak premične opore 21.In addition, we do not change the rate of tightening of the bundle forming the spring when the retaining bolt of the movable support 21 is loosened for any reason.

Zgoraj opisana izvedba z aplikacijo inovacijskih principov predloženega izuma je seveda podana kot primer takšnih inovacijskih principov in se ne sme oceniti kot omejitev obsega izključne pravice, ki se tu zahteva.The embodiment described above with the application of the innovation principles of the present invention is, of course, given as an example of such innovation principles and should not be construed as limiting the scope of the exclusive right claimed herein.

Podrobneje, pritrdilna naprava prikazana na razdeljevalcu proizvodov se lahko uporablja pri katerikoli vibracijski napravi z listnato-vzmetno obeso. Poleg tega, pritrdilno napravo lahko uporabljamo po potrebi tudi za povezavo listnate vzmeti z vibrirajočim krožnikom.In particular, the mounting device shown on the product distributor can be used with any leaf-spring vibrating device. In addition, the attachment device can also be used to connect the leaf spring to a vibrating plate as needed.

Število pritrdilnih elementov z navojem raznih komponent bilo prikazano, in tudi njihov položaj je lahko različen.The number of threaded fasteners of the various components was shown, and their position may also be different.
