But in some purposes, it is suitable using the rewinding machine of moderate dimensions, specifically will meet the needs of the emerging market that does not need high production speed.
In order to satisfy these needs, in WO-A-97/32804, described and developed the moderate especially peripheral rewinding machine of a kind of size.This rewinding machine is provided with a kind of special reel system, and has the device of the final free edge that is used for the gluing volume that is positioned at coiling support downstream.In general, the unloading of finished product volume and gluingly need the manufacturing line circulation slack-off so that obtain the correct location of free edge of the gluing Web materials wanted so that can seal this volume.
Summary of the invention
The object of the present invention is to provide particularly a kind of but be not unique be the machine of periphery or surface type, thereby therefore it has moderate size and carries especially easily and occupies little space in use.
The present invention is to provide a kind of rewinding machine that is used to produce coiling Web materials volume, it comprises: a peripheral reel system, this system comprises a coiling support, this support has first take up roll and second take up roll that forms a gap betwixt of carrying Web materials thereon, and described Web materials is transported in the described gap; A system that is used to cut off Web materials, this system cut off Web materials when the coiling of each volume is finished, thereby form free final edge and free initial edge; With an adhesives applicator that is used for application of adhesive, this adhesives is used to seal the free final edge of every volume Web materials, described applicator comprises some nozzles, and these nozzles are directly injected to described adhesives on the described Web materials of upstream of the volume that is in the stage of finishing in the coiling support; Provide described nozzle with suitable quantity and suitable interval, guaranteeing bonding Web materials on whole width, described nozzle when the winding portion of described volume finishes under the situation that the feed rate of the described Web materials by described gap does not slow down application of adhesive.
According to a concrete aspect, a further object of the invention is to produce a kind of small-sized machine, and wherein the delivery speed of Web materials needn't reduce at last in each circulation of reeling.
In fact, those of ordinary skills can realize at a kind of rewinding machine by the these and other objects and the advantage of reading following content and will understand that, this rewinding machine is equipped with the reel system of the center of being substantially or peripheral type and has and is used at each coiling on-cycle final cutting Web materials so that produce final edge and the system of initial edge, and wherein the adhesives applicator is coated in adhesives in reel system on the final free edge of each volume of the upstream position that is arranged in the volume that is in the coiling final stage.
Desired opposite with the present invention, when unloading this volume from described system, the general adhesives that will be used to seal free edge in the downstream of reel system is coated on the final edge or volume.For this reason, be typically provided with the sizing machine that matches, it and rewinding machine are provided with in line, perhaps are inserted with memory storage.This makes this manufacturing line complicated and huge.
On the contrary, adhesives is coated on the end of Web materials before being wound on Web materials on the volume and before from reel system, this volume being unloaded according to the present invention.This makes that this machine is compacter and can realize other advantage, and it is clear that these advantages will become at the appropriate time.
US-A-4487377 has described a kind of system, wherein before finishing volume adhesives is coated on the final edge of Web materials.But in this case, adhesives directly is not coated on the Web materials by applicator.On the contrary, adhesives is transported on the coiling core, and this core when it is inserted in reel system with coated some adhesive transfer thereon to final edge so that realize its involution.This known solution has tangible limitation.
Specifically, it can only be applied to special reel system and can only be applied to cut off this Web materials and introduce the particular system of new coiling core.In addition, it can not be applied in these situations, promptly is wound under the situation that does not have central core and carries out.What also should keep firmly in mind is, for the final free edge of volume use identical adhesives and initial free edge is anchored on the coiling core so as starting subsequently the coiling of volume not necessarily feasible or suitable.

Shown in the embodiment of embodiment in, be provided with layer adhering device 101 along path from the Web materials N of lamination/embossing device 61, this device comprise one with layer adhering roll 105 an interactional cylinder 103, this layer adhering roll with expand into high-voltage expansion tank 107 and be squeezed on the cylinder 103 under the pressure by one or more.Layer adhering device 101 can use outside embossing device 61, when for example operating under knurling rolls are not having the situation of adhesives, because it does not have distributing box 83 or because of embossing device withdraw from use.This does not get rid of the possibility that this machine lacks embossing device 61 and only is equipped with layer adhering device 101, described layer adhering device be used for for example by on around the roller 91 by and suitably be transported to two-layer V1 on layer adhering device 101, V2 links together.Can also arrange like this that a layer adhering device 101 do not have fully and this machine is provided with embossing individually with laminater 61 and have relevant adhesive dispenser 83.In this case, the path of Web materials N will change a little.
Along the path of Web materials N, between layer adhering device 101 and coiling support 5, be provided with perforating device 111, this perforating device comprises the insert supporting roller 113 of rotation and the stationary roll 115 that is carrying counter blade.Perforating device 111 can be traditional type and be not elaborated.
The Web materials that passes perforating device 111 has a series of perforated lines vertical with vertical direct of travel of Web materials, and these perforated lines are divided into a series of paper slips or the scraps of paper so that use to the end user subsequently with Web materials N.
Punching Web materials from perforating device 111 passes through on cylinder 117, and therefrom round first take up roll 7 so that advance on the coiling support.
Interactional with first take up roll 7 is series of spray nozzles 121, and they are used for adhesives is coated in that Web materials N goes up so that separately during coiling end of volume carrying out the involution of the final free edge of Web materials at each by cutting off parts 27 after cutting off these Web materials.
As the same shown in clearly among Fig. 1, nozzle 121 is (with suitable quantity and proper spacing setting with the All Ranges on the length of guaranteeing correctly to be adhesive in volume, in other words on the width of Web materials) be arranged in such a way, therefore promptly before described Web materials enters in the passage that is limited by take up roll 7 and rolling surface 25 and be used to cut off before parts 27 effects thereon of Web materials, the desired moment with adhesive spray to Web materials.The adhesives that is used for sealing this volume like this, subsequently was applied to before Web materials is cut off on this Web materials.
Be easily, these nozzles 121 can relative to each other be spaced from each other by this way, thereby the adhesives that is distributed can not influence those zones that contact with cut-out parts 27 of Web materials N, cuts off parts like this and just can not made dirty by adhesives in each cycle period of reeling.
And be that the suitable timing of the effect by these two parts can prevent to cut off parts 27 and be made dirty by the adhesives that is ejected by nozzle 121 more easily.Specifically, the same as known from the prior art obtained, cutting off parts 27 can be with respect to the perforated lines location that is formed on Web materials N by perforating device 115, thereby by be wound between cylinder 7,9 and 11 volume and and cut off position between the contact point between parts 27 and the described Web materials and tear and cut off this Web materials, in other words be clipped in the position that cuts off between the parts 27 and first take up roll 7 at Web materials.Because the adhesives that is applied by nozzle 121 will be retained on the end or afterbody that is being wound on the Web materials on the volume that to be ready finishing, so nozzle 121, beam bear 111 and cut-out parts 27 can be located so mutually, thereby carry out when described perforation is positioned at the position enough far away from the zone of action of described parts at the cutting action that carries out on the Web materials by cutting off parts 27, Web materials along described perforated area owing to the clamping action that cuts off parts 27 separate, thereby spray to adhesives on the Web materials in advance reliably at Web materials with cut off outside the contact area between the parts 27 by nozzle 121.
Used series of spray nozzles 53 adhesives to be coated to the explanation of the possibility on the tubular core A before tubular core being inserted between rolling surface 25 and the take up roll 7 though the front provides, this does not get rid of by described nozzle 121 coatings and is used for the initial free edge of Web materials is anchored at the possibility that coiling core A goes up required adhesives.For this reason, described nozzle can be actuated twice, once be used for adhesives is coated on the zone of Web materials N, this zone will form afterbody or the end of rolling up by cutting off parts 27 after cutting off, and be coated to the second time with Web materials that tubular winding core A contacts on.Also have in this case, can also interrupt the conveying of adhesivess, made dirty by adhesives so can prevent to cut off parts 27 by nozzle 121.In practice, cutting off parts will act between two linearity region of adhesives, and more forward one is used for sealing the finished product volume, and a coiling that is used for starting subsequently more backward.
When the adhesives at the final edge that is used to seal volume is anchored at adhesives on the core when having different character and characteristics with being used for initial edge, using two kinds of nozzles 53 and 121 is easily.This depends on the product type and/or the winding speed of being reeled.
Fig. 2,3 and 4 demonstrates three continuous stages in the operating winding of a volume Web materials.
In Fig. 2, volume R is in the intermediary of formation.In this embodiment, new core A has located to prepare insertion subsequently.Fig. 3 shows the ending phase of the coiling that makes the test, and has partition member, and it rotates and enter the passage that is limited between rolling surface and the last take up roll 7 along the direction of arrow f27.Nozzle 121 sprays the adhesives that is used to seal final edge.On also demonstrating before Web materials cuts off by Web materials N, Fig. 3 adhesives is transported to stage on the new core A by nozzle 53.This conveying is compared with the conveying of being undertaken by nozzle 121 to be simultaneously or staggered in time and especially to shift to an earlier date.Fig. 4 demonstrates the stage subsequently, wherein new core A is inserted in the passage that is limited between rolling surface 25 and the take up roll 7, thereby contacts with described rolling surface and contact with the Web materials N that passes through on take up roll 7.In the downstream that cuts off parts, Web materials N has been torn the final edge LF that will be wound up at last on the R to form, and is coated with adhesive C by nozzle 121 on it.LI represents to be wound up into the initial edge on the new core.Unloading volume R carries out in a kind of known mode from the coiling support.
In an illustrated embodiment, this machine also has printing device 131, this device comprises and is coated with black device 133, screen drum 135 and plate cylinder 137, and this plate cylinder is carrying and is being printed on layout, decorative pattern, text etc. on it other will be printed on the forme of the information on the Web materials.In this embodiment, have only the layer V1 of Web materials N will advance on the pass rotary drum 139, this cylinder and plate cylinder 137 mutual actions, and another layer V2 do not advance to embossing device with printing or may directly advance on layer adhering device.
