[20] see figures.1.and.2, described open-width-lapper 1 comprises two banding pattern transmitters 10 and 11, and the banding pattern transmitter 14 of an output.
[21] the banding pattern transmitter 10 of described input comprises a circle transmission band 100, and it is centered around on deflector roll (the rouleaux de guidage) 101a to 101l along a closed path, and wherein at least one deflector roll is power operated, to drive described transport tape 100.According to the present invention, but described transport tape 100 indistinction ground are for that breathe freely or sir-tight.
[22] in described deflector roll, two deflector roll 101a, 101b are contained in going up on the input balladeur train 12 of an activity in a usual manner, and install with respect to described balladeur train 12 by their center shaft with rotating freely.Described deflector roll 101j, 101k and 101l are contained on the following output balladeur train 13 of an activity in a usual manner, and install with respect to described balladeur train 13 by their center shaft with rotating freely.Describedly go up balladeur train 12 and but described balladeur train 13 translations are down moved, and be furnished with and allow described two balladeur trains actuating device (not shown) of moving of translation alternately in two opposite sense D and G.
[23] described banding pattern transmitter 11 comprises a transport tape 110, and it is centered around on the deflector roll 111a to 111j along a closed path, and wherein at least one guide rail is power operated, to drive described transport tape 110.Deflector roll 111a to 111d is contained on the described movable carriage 12 in a usual manner, and installs with respect to described balladeur train 12 by their center shaft with rotating freely.Described deflector roll 111e is contained on the described movable carriage 13, and installs with respect to described balladeur train 13 by its center shaft with rotating freely.
[24] when operation, described balladeur train 12 and 13 and the deflector roll that for this reason is contained on these balladeur trains synchronously carry out motion of translation back and forth along opposite direction D and G.
[25] at the inlet E place of described open-width-lapper 1, described non-woven material WE (it is for example made with a unshowned carding machine in described open-width-lapper upstream) is placed on the surface of described input transport tape 100.This non-woven material WE is regional by the folder bundle that described transport tape 100 is transferred into described non-woven material, and this folder bundle zone is between described two transport tapes 100 and 110 (between described deflector roll 111e and 101j).Because the translation back and forth synchronously of described balladeur train 12 and 13, described non-woven material WE bears alternately moving back and forth on described two opposite sense D and G, this allows alternately described non-woven material WE on the surface of self superimposed transport tape 140 at described output transmitter 14.This transport tape 140 becomes transversal orientation with respect to the Way in (arrow F) of described non-woven material WE, and moves on the direction of arrow K (Fig. 1).Outlet S at described open-width-lapper 1, obtain a thick multilayer non-woven material WS, this multilayer non-woven material is by a plurality of nonwoven layers WEa, WEb, WEc ... form, described nonwoven layers is overlapped mutually, and described multilayer non-woven material WS is output along described direction K in the exit.
[26] with reference to Fig. 2, described input transport tape 100 comprises a straight line portion 100a who rises, and this straight line portion extends between two deflector roll 101d and 101c, and it is labeled as angle A with respect to horizontal inclination angle.The height and position of described deflector roll 101d is preferably adjustable, so that the value scalable of described inclination angle A.Similarly in some cases, the height and position of described deflector roll 101d is transformable in operational process, thereby makes the value of described inclination angle A change in the moving process of described transport tape 100.
[27] slide at the rising part 100a place of described input transport tape 100 for fear of described non-woven material WE, described open-width-lapper 1 of the present invention is furnished with ionization device, and in the special embodiment of accompanying drawing, described ionization device is realized with the form of an ionization bar 15.In this embodiment, described input transport tape 100 is implemented and is used as connected to chassis ground wire (masse) by a conductive material (as metal).
When [28] moving, described ionization bar 15 can produce a powerful electric field 15a who is full of ion, and this electric field is called ionized field, and represents with imaginary point in Fig. 2.Therefore, described ionization bar 15 comprises for example a plurality of electrodes or high potential point, and described a plurality of electrodes or high potential o'clock are by direct current high-voltage generator (not shown) power supply and can produce for example negative ion in the part.
[29] especially, described ionization bar 15 be installed in described transport tape 100 rising part 100a the surface the top and near this surface, and towards the moving direction F lateral extension of the rising part 100a of described transport tape 100.
[30] preferably, go out as depicted in figs. 1 and 2, described ionization bar 15 be positioned at described deflector roll 101d near, promptly in the entrance of described rising part, be right after the downstream of the described transition region between described upstream transmission device T and the described input transmitter 10.
[31] especially, described ionization device 15 produces an ionized field 15a, and described ionized field preferably goes up extension in whole length (L) of described non-woven material WE at least.
[32] when operation, when described non-woven material WE enters in the described ionized field 15a, static on the fiber of described non-woven material WE and/or the long filament band, and be close on the transport tape surface of described rising part 100a by their electrostatic charge.Therefore, described non-woven material WE is attached on transport tape 100 surfaces at described rising part 100a place tightly.The static of described non-woven material WE keeps making can advantageously avoid the sliding phenomenon of described non-woven material WE on this rising transporting part 100a.Therefore, particularly can on described rising part 100a, transmit described non-woven material WE in more speed ground, and/or can transmit heavier non-woven material WE, and/or can increase the inclination angle A of described rising part, can the quality of described non-woven material WE not caused damage simultaneously.
[33] when operation, in case described non-woven material WE passes described ionized field 15a and is with static at it during by described ionized field 15a, described non-woven material WE then discharges gradually by described transport tape 100.
[34] preferably and not necessarily, described ionization device 15 is set, so that the electrostatic charge of described non-woven material WE enough makes the static of described non-woven material WE be attached to the surface of described transport tape 100, at least up to the end of described rising transporting part 100a, promptly in described example up to deflector roll 101c place.
[35] according to application, particularly, can one or more additional ionization bar be set for example at described rising part 100a place according to the length of described rising part, be used for making in case of necessity the described non-woven material WE on the described rising part 100a to be with static.Can also additional ionization device be set in the downstream of described rising part 100a, as the ionization bar among Fig. 2 15.
[36] described ionization bar 15 can by any make described non-woven material WE can be at least static is attached at described transport tape 100 in described rising transporting part 100a equivalent elements replace.Especially, described ionization bar 15 can be replaced by the littler juxtaposed a plurality of ionization sources of size.Similarly, in another modification, be that described transport tape 100 is with static; In another modification, described non-woven material WE and described transport tape 100 can be with static and charged polarity opposite simultaneously.
[37] though preferred described non-woven material WE and/or described transport tape 100 are with static on whole at least length L of described non-woven material WE, yet this feature is dispensable.--for example at their place, two edges partly or in a middle section partly--makes on the described non-woven material band static and its electrostatic adhesion got final product to implement its confirmation in modification at another: only need on the part of described non-woven material WE width, and described middle section wherein is not extended to the edge of described non-woven material.
Therefore [38] in the open-width-lapper of some type, during operation, described input transport tape 100 speed are driven changeably, and bear more or less unexpected and the acceleration and the deceleration that repeat.Because the present invention, described non-woven material WE ideally keeps being close on the surface of described transport tape 100, and it can more easily bear described velocity variations, does not have the danger of sliding or breaking away from respect to described transport tape surface.This result especially realizes in the rising part 100a of described transport tape 100 and is benefited.Yet it also advantageously may be implemented in any such application: a non-woven material (single or multiple lift) is transferred on the transport tape surface in its transporting part that bears velocity variations (quickening or deceleration); Described transporting part can be upstream or downstream (promptly being inclined relative to horizontal), perhaps can be level on the contrary.
More at large, the present invention is not the inlet that limitation is used for one open-width-lapper, can similarly apply to any conveyer belt, described conveyer belt makes and can transport a non-woven material in its surface, and has a transporting part that rise and/or velocity variations when bearing operation.But (as the part 100a of example as described at Fig. 1 and Fig. 2) of the part straight line rising of described transport tape and/or that bear velocity variations, but can partly or entirely be curve also.
