DESCRIPTION of the invention which has as its title: PROCEDURE AND DEVICE FOR STORING PIECES PI A ON A SUPPORT "

SUMMARY

Procedure for depositing or applying pieces

in support, characterized by the fact that the pieces are grasped at their ends? front and come? no dragged with their extremity? free rear?

blown against 1 support itself

example a transporter or a Support, as well as? a di- [

I.? imp ilation of flat bags produced by a special *

in a given formation, on a support or on a conveyor. This deposit must take place with severance and in the position and s.ati a, _sopr_at.tu.t.to se? flat pieces are made of thin materials,: .light and prone to wrinkle,! What, if sufficient fastening on conveyors and supports cause it to move, deform and form folds. The aim of the present invention? then to raise a deposit or application of pieces Flat of a conveyor or on a support in a safe way, stopped and in position c or r e t t a

This task is solved in a procedure of the type mentioned at the beginning with the s? that the pezi are grasped at their ends? front and are dragged over the support with their ends? dangling rear and are sucked in or? offered against support itself. According to the process according to the invention, the pieces can be deposited in a safe and stably stopped manner on devices which carry on their transport or on supports, or spread over these. since? the pezj; the plates adhere ^ gi? due to the effect of the sucked air, or of the air I blew at, at the [support _od al

traction on this developed. Since? the pieces-. to the plates, according to the procedure conforming to the invention_ are ... dragged .by effect of abstraction-. exercised ... on their ends. -front. above.appog gi. to which they adhere .. with the. their ends? .that.

in the sense of motion, they come means in. voltage- * ion cos? which, particularly light material, can wrinkle, and can be limp. be ferene handled.

In further perfection of the invention pieces, to be deposited in imbricated formation on a conveyor with suction belts, are released free at their ends. front as soon as they have been dragged over the last piece of the place previously, and aspirated to its extremity? posterior, of a stretch equal to the length of reco-? _ riment. The flat pieces thus deposited in an exact position and in a stationary manner on top of a suction belt conveyor, can be conveyed to further processing stations or to a stacking apparatus.

For example, to produce shirt-type bags, made of flexible tube, with side folds with gussets and closed at both ends? by means of transverse welded sutures, they can be dragged to their e-f Stremit? anteriorly on a support, being approached under pressure by means of a current of blown air. a_contr_o_ll support itself. tube ~? lessibl? the above 1. support, i r i t agl i_a _c amie loia ,.

From the suction belt 46, the overlapping pieces 15 are detected by the overlapping suction belt conveyor 48, the suction belt of which run on the driving drums. vio 49,50,51. Through the individual separate suction belts 48, the teeth_of a collision 52 protrude. bile, which are fixed on a tree 53.

Under the collision 52 tipper? disposed a feed belt 54, which runs around the drive and return drums 55 56, 11 stacking belt 54? shaped in such a way that it can be lowered and approached against the belts of the overlapping suction belt conveyor 48 * Correspondingly, the transport ator / n superimposed suction belts, the belts of which run around the drive and return drums 58, 59? detects the separate group of pieces 15 superimposed on each other in an overlapping manner carried by the conveyor 30 with suction belts beyond the return drum * These pieces are deposited? ? iap? lament? which runs around the drive and return drums 62 and 63 * As soon as the battery adduced? been deposited in front of the folding collision 60? this rotates upwards around the shaft 64? so that the completed stack can? be removed * Even the tape 61 of foil can? be lowered as the height of the pile increases and can to be approached against the belts of the conveyor 57 with overlapping suction belts? the air is expelled by pressure from the completed pile and this can be extracted from the plant by simultaneously activating the commands of the two conveyors upstream, the finished piles can then be taken from the conveyor belt conveyor for piles 54 * 61 * The modalities? of work of the installation device described above have been illustrated more? more specifically in the previous German patent application P 2 $ 32660 * 5-27 of the Applicant * In practice, the details of implementation and realization may in any case vary without departing from the scope of the invention and therefore from the domain CLAIM 1} Procedure for depositing or applying flat pieces on a support, or example? a carrier or a support, characterized by the fact that the pests are grasped at their front end and are dragged with their extremities. free rear? leaning over the support, and sucked plug blown oohtro the support itself *> S) Process according to claim i? Ca * reaffirmed by the fact that? pieces to be deposited in imbricated formation on a conveyor with suction belts, are left free at their ends. front as soon as layers are dragged over the last piece deposited previously cd aspirated at its extremity? back for a section equal to the covering length * 3) Process according to claim 1, characterized in that in order to smoothly deposit a single piece on a support, this piece is blown against said support and is dragged by its front edge over the support itself * 4) Process according to claim 3, characterized by the fact that during the dragging of the piece onto the support, the piece is ejected from it. 5) Device pcs for carrying out the procedure according to claim 1, characterized by the fact that? provided with a conveyor and / or belts, belts or chains without conveyor belts, cbs run over t rollers or wheels for return chains, to which belts, belts or chains are fixed transversely to the direction of advancement, retention rules, whose retaining equipment are provided equipped with controls to free 1 pieces from them rulers grasped at their estrosit? anterior, and which, due to the inferior branch of the conveyor, at a distance less than the length of the possible,? I * displace a suction belt conveyor * 6) Device according to claim 5, characterized by the fact that the suction belt conveyor is followed by a double belt conveyor * whose entrance slit? equipped with an * appo? guide enclosure for the whole of the imbricated pieces * overlapping * and a second conveyor to the no? on which a return drum, shaped as a suction roller, of a third suction belt conveyor can be lowered? !! which nanny * bure can? accompany the motion of the second conveyor to suction belts at least with the same speed? of transport of this little suit, or can? come lifted? and that the suction belts of the conveyors are equipped with suction holes whose suction cria can? be regulated in such a way that the transporters can * separately aspirate successive countries? overlapping one another? on the first conveyor? 7) Device for carrying out the method according to claim 30 4, characterized in that? provided for a conveyor with belts, belts or endless transport chains, which run over drums, rollers or wheels for return catane, to which belt? belts or chains are fixed transversely to the direction of advancement of the retention rules, which in the area of the * end rear and / or under the lower section of the conveyor? arranged a support with a window, on which? oriented at least one nozzle blowing an air stream which is inside the conveyor, and which? provided a profiled line fixed to a controlled oscillating lever? which crosses the support passing through the cutout according to the rate of removal of the pieces, 8) Device according to claim 7 characterized by the fact that the support? consisting of a grid formed by bars. 9) Device according to claim 7 or 8, characterized by the fact that the cutout of the support and the profiled blade, have the shape of re? cuts of shirt bags?
