Description
15 20 25 30 35 mâtásvarande pinnar eller andra organ, "14 a . som förs in fran matrisens motsatta sida. Den fullständiga rensningsanordningen omfattar då en horisontellt monterad matris med ett antal hål_ svarande mot de avfallsbitar, som skall rensas ut ur de stan- sade arken, vidare en patris med en horisontellt monterad 'lä skiva försedd med ett antal nedåt utstickande organ i form av fingrar eller skivor. Slutligen finns mot patrisens utstickande 1.» organ svarande liknande organ, som är monterade på lämpliga hållare och sträcker sig uppåt genom hålen i matrisen mot de utstickande organen hos patrisen på ett sådant sätt, att avfallsbitarna från arkmaterialet kläms fast mellan dessa underifrån kommande organ och de utstickande organens hos patri- sen. För att avlägsna en spillbit krävs då en rad operationer, nämligen att utstickande organ förs in underifrån genom hålen i matrisen, att patrisen förs ned så att spillbitarna kläms fast, att patrisen och de underifrån utstickande organen samtidigt förs nedåt och därvid för med sig spillbitarna genom hålen i matrisen, att de utstickande organen hos patrisen och underifrån kommande utstickande organ förs från varandra så att avfalls- bitarna frigörs och slutligen att patrisen åter förs upp, så att dess utstickande organ befinner sig i ett läge ovanför matrisen, så att ett nytt stansat ark kan föras in över matrisen. 15 20 25 30 35 measuring sticks or other means, "14 a. Which are inserted from the opposite side of the matrix. The complete cleaning device then comprises a horizontally mounted matrix with a number of holes_ corresponding to the pieces of waste to be cleaned out of the punched the sheets, furthermore a patris with a horizontally mounted 'reading disc provided with a number of downwardly projecting members in the form of fingers or discs. means corresponding to similar means, which are mounted on suitable holders and extend upwards through the holes in the matrix towards the protruding means of the patris in such a way that the pieces of waste from the sheet material are clamped between these from below coming means and the protruding means of the patrician. In order to remove a waste piece, a series of operations is then required, namely that protruding members are inserted from below through the holes in the matrix, that the patrician is lowered so that the waste pieces are clamped, that the patrician and the bottom-protruding members are simultaneously moved downwards. the holes in the matrix, that the protruding members of the patrician and protruding members coming from below are moved apart so that the pieces of waste are released and finally that the patrician is brought up again so that its protruding members are in a position above the matrix so that a new punch sheets can be inserted over the matrix.
Föreliggande uppfinning avser att eliminera de nackdelar, som är förbundna med ovan beskrivna anordningar för rensning av stansat arkformigt material. Det är sålunda med en anordning enligt uppfinningen möjligt attavlägsna avfallsbitarna utan risk för att de hänger kvar i någon kant och därmed ställer till problem i den fortsatta hanteringen. Genom uppfinningen undviks också komplicerade anordningar och flera arbetssteg för atthålla fast avfallsbitarna under avlägsnandet. Detta uppnås genom att utforma matrisen med de särdrag, som anges i den kännetecknande delen av patentkrav 1.The present invention aims to eliminate the disadvantages associated with the above-described devices for cleaning punched sheet material. Thus, with a device according to the invention it is possible to remove the waste pieces without risk of them remaining in any edge and thus posing problems in the continued handling. The invention also avoids complicated devices and several work steps for holding the pieces of waste during removal. This is achieved by designing the matrix with the features set out in the characterizing part of claim 1.
Uppfinningen skall i det följande beskrivas i anslutning till bifogade figurer.The invention will be described in the following in connection with the accompanying figures.
Fig. 1 visar exempel på en matris enligt uppfinningen.Fig. 1 shows an example of a matrix according to the invention.
Fig. 2 visar en mot den i fig. 1 visade matrisen svarande patris. 10 15 20 25 30 35 462 524 Fig. 3 visar i genomskärning utmed linjen A - A matrisen i fig. 1.Fig. 2 shows a matrix corresponding to the matrix shown in Fig. 1. Fig. 3 shows in section along the line A - A the matrix in Fig. 1.
Fig. 4 visar i genomskärning utmed linjen B - B patrisen i fig. 2.Fig. 4 shows in cross-section along the line B - B the pattern in Fig. 2.
Fig. 5 och 6 visar i princip i genomskärning utmed linjen C - C matrisen enligt fig. 1 under en arbetscykel, varvid patrisen förts så långt mot avfallsbiten som skall avlägsnas att denna börjat lossa från ämnet. I figuren visas ocksådelar av från patrisen utstickande delar.Figs. 5 and 6 show in principle in cross-section along the line C - C the matrix according to Fig. 1 during a work cycle, the patrician being moved so far towards the piece of waste that is to be removed that it has begun to detach from the blank. The figure also shows parts of parts protruding from the patrician.
Den i fig. 1 visade matrisen enligt uppfinningen består av en skiva 1. I skivan finns upptaget ett antal hål 3, 4, 5, 6, vilkas form svarar mot de avfallsbitar, som skall avlägsnas från de stansade arken. På matrisskivans ovansida finns vid varje hål två flikar 7 - 14. Den i figuren visade skivan är även fàßemímed fyra hål 15, 16, 17, 18, vilka är avsedda för fastsättning eller styrning av matrisen- Dessa hål kan givetvisa variera både vad gäller antal och placering beroende på den avsedda tillämpningen.The matrix according to the invention shown in Fig. 1 consists of a disc 1. A number of holes 3, 4, 5, 6 are accommodated in the disc, the shape of which corresponds to the pieces of waste which are to be removed from the punched sheets. On the upper side of the matrix plate there are at each hole two tabs 7 - 14. The plate shown in the figure is also fàßemímed four holes 15, 16, 17, 18, which are intended for fixing or guiding the matrix- These holes can of course vary both in terms of number and location depending on the intended application.
Figur 2 visar en mot matrisen i fig. 1 svarande patris.Figure 2 shows a matrix corresponding to the matrix in Figure 1.
Denna består av en skiva 2, försedd med ett antal utstickande organ, i detta fall tunna skivor 20, 21, 22 och 23. Skivornas form motsvarar i princip formen hos hålen i patrisen men med något mindre utsträckning i längd och betydligt mindre bredd.This consists of a disc 2, provided with a number of protruding members, in this case thin discs 20, 21, 22 and 23. The shape of the discs corresponds in principle to the shape of the holes in the patricia but with a somewhat smaller extent in length and considerably less width.
Av figur 3 framgår, att matrisskivan 1 består av en platta 24, som är belagd med en tunn skiva 19, i vilken flikarna 7, 9 och 11 utformats utstickande över hålen 3, 4 och 5.From figure 3 it can be seen that the matrix disc 1 consists of a plate 24, which is coated with a thin disc 19, in which the flaps 7, 9 and 11 are formed projecting over the holes 3, 4 and 5.
Figur 4 visar på samma sätt ett tvärsnitt genom patrisen enligt figur 2, varav framgår de mot hålen svarande skivorna 20, 21, 22.Figure 4 similarly shows a cross section through the partition according to figure 2, from which the discs 20, 21, 22 corresponding to the holes can be seen.
Figurerna 5 och 6 visar i princip arbetssättet hos en matris enligt uppfinningen. Figurerna visar i tvärsnitt utmed linjen C - C i figur 1 bottenplattan 24 hos matrisen och den ovan- på denna liggande tunnare skivan 19, vari utformats flikar 7 och 8. På matrisen är placerad ett ark 29, ur vilket skall avlägsnas en avfallsbit 28. Detta uppnås genom att den i figur 5 visade skivan 25, som är fastsatt på en i figuren ej visad 10 15 20 25 30 401 324 _4 patris, förs i riktning nedåt. Härvid kläms avfallsbiten 28 fast mellan flikarna 7 och 8 och skivan 25. Då skivans rörelse fortsätter nedåt böjs flikarna 7 och 8 och ytter- kanterna av avfallsbiten 28. Skivans rörelse nedåt fortsätter så långt att avfallsbiten helt har passerat flikarna 7 och 8.Figures 5 and 6 show in principle the working method of a matrix according to the invention. The figures show in cross section along the line C - C in figure 1 the bottom plate 24 of the matrix and the thinner disc 19 lying on top of it, in which tabs 7 and 8 are formed. A sheet 29 is placed on the matrix, from which a piece of waste 28 is to be removed. This is achieved by moving the disc 25 shown in Figure 5, which is attached to a partition not shown in the figure, in a downward direction. In this case, the piece of waste 28 is clamped between the tabs 7 and 8 and the disc 25. As the movement of the disc continues downwards, the tabs 7 and 8 and the outer edges of the piece of waste 28 are bent downwards so far that the piece of waste has completely passed the tabs 7 and 8.
Genom att avfallsbiten på detta sätt i början av sin nedåt- riktade rörelse är fastklämd mellan flikarna och skivan, lossas avfallsbiten med säkerhet utmed hela sin omkrets från det arkformiga materialet. I figur 6 visas en alternativ utföringsform, där den i patrisen fastsatta skivan 25 har bytts ut mot två pinnar 26 och 27. Funktionen är i övrigt densamma som beskrivits ovan.Because the piece of waste is in this way at the beginning of its downward movement clamped between the flaps and the disc, the piece of waste is securely detached along its entire circumference from the sheet-shaped material. Figure 6 shows an alternative embodiment, where the disc 25 fixed in the partition has been replaced with two pins 26 and 27. The function is otherwise the same as described above.
Det har visat sig lämpligt att låta de på patrisen fastsatta skivorna ha en utsträckning i längdled, som är så stor att, då skivorna förs ned i motsvarande tomma hål, de precis går fria från flikarna, dvs. skivans längd är obetydligt mindre än längden hos den fria öppningen i hålet. Flikarnas största nedböjning under rensningsoperationen är då ca 300 hos rensningsanordningen erhålls. och en mycket säker och tillförlitlig funktion Flikarna kan utföras i olika material, från fall till fall. packningar har det t.ex. vilket får väljas Vid stansning av kartong för mindre för- visat sig lämpligt att välja flikar av en några tiondels millimeter tjock, styv plastfolie. Flikarna har ovan beskrivits såsom utgörande en del av ett ytskíkt på matrisen, men de kan naturligtvis också utgöras av mindre Flikarna kan bitar, som är fastsatta på matrisens ovansida. också vara utförda i annat material än plast. Matrisen i övrigt kan vara gjord exempelvis av en 10 till 25 mm tjock lamellträskiva, vars längd och bredd ofta ligger inom inter- vallet 200 till 900 mm. att variera flikarnas längd inom förhållandevis vida gränser.It has proved appropriate to allow the discs attached to the pad to have a longitudinal extent which is so great that, when the discs are lowered into the corresponding empty holes, they just go free from the flaps, i.e. the length of the disc is slightly less than the length of the free opening in the hole. The largest deflection of the flaps during the cleaning operation is then about 300 of the cleaning device is obtained. and a very safe and reliable function The tabs can be made of different materials, from case to case. gaskets have it e.g. which may be chosen When punching cardboard for less, it has proved appropriate to choose tabs of a few tenths of a millimeter thick, rigid plastic foil. The flaps have been described above as forming part of a surface layer on the matrix, but they can of course also consist of smaller flaps can be pieces, which are attached to the top of the matrix. also be made of a material other than plastic. The matrix can otherwise be made, for example, of a 10 to 25 mm thick lamella board, the length and width of which are often in the range of 200 to 900 mm. to vary the length of the flaps within relatively wide limits.
