Abstract
Description
- The present invention relates to a folding machine to fold a web material along transverse folding lines. More specifically, the invention relates to a folding machine of the type comprising a pair of adjacent counter-rotating folding cylinders having parallel axes, each of which has at least one gripping member to grasp the web material along transverse lines and make folds along said lines.
- The invention also relates to a means to perform folding of a continuous web material according to transverse zigzag lines.
- In many folding machines used in the field of paper converting to produce, for example, folded paper napkins, a continuous web material - optionally previously folded along a longitudinal line - is fed to a pair of counter-rotating folding cylinders, disposed adjacent to each other to define a nip through which the web material passes and having parallel axes. Disposed on each cylinder are members that make the fold in the web material. The aforesaid members are disposed and controlled so that the web material is folded in a zigzag manner, adhering alternately first to one and then to the other of the two counter-rotating folding cylinders. The pack formed of the zigzag folded web material is then cut by a blade and divided into two piles of paper napkins or similar folded products.
- A machine of this type is described for example in
WO-A-9728076 US-A-4 332 583 and inWO-A-0162651 US patent 3.195.882 , inUS patent 3.229.974 , inUS patent 3.820.774 , inUS patent 3.689.061 , inGerman patent 4.446.753 and inGerman patent 429.288 . - The folding members of these folding machines include, disposed on each folding cylinder, a gripping member, which grips the web material along a folding line at each turn of the cylinder. To insert the web material into the gripping member, respective folding blades or wedges are disposed on the two folding cylinders, in positions angularly staggered with respect to the gripping members. To make a fold a folding blade of one of the two folding cylinders and a gripping member of the other folding cylinder are disposed in angular positions so that they correspond with each other in the nip defined between the two folding cylinders, so that the web material is pushed by the folding blade inside the gripping member.
- Typically, each of the two folding cylinders has at least one folding blade and one gripping member, so that for each complete turn of the pair of folding cylinders at least two folds are made on the web material.
- The presence of folding blades and gripping members on the counter-rotating folding cylinders makes these machines particularly complex from a mechanical viewpoint. Moreover, the mechanical action of the folding blade or wedge on the web material tends to damage it. The folding blades are subject to rapid wear with consequent maintenance costs.
- Folding machines of another type and with a different configuration to those to which the present invention relates are described in
US-A-5,356,131 ;US-A-4,921,235 ;WO-A-03016184 - The object of the present invention is to produce a folding machine of the aforesaid type, which is simpler, white at the same time efficient and reliable.
- This and further objects and advantages, which shall be apparent to those skilled in the art by reading the text hereunder, are obtained essentially with a folding machine according to
independent claim 1. - The continuous web material (typically and preferably tissue paper for producing handkerchiefs or napkins and the like) is thus engaged alternately on one and on the other of the counter-rotating folding cylinders by suction, and said suction which engages the web material in equidistant areas causes the zigzag folding thereof, without the need to use complex mechanical members to grip the material with relative cam mechanisms to control them. This simplifies the machine, also making it efficient and reliable.
- To facilitate folding and, optionally, to obtain particularly reliable operation even at high speeds, according to the invention each of the folding cylinders is provided with a wedge element in phase with the gripping member of the opposed cylinder, to produce a line which facilitates folding in the web material, at the level of said gripping member. The line which facilitates folding is in substance a sort of crease and can be obtained in a particularly efficient way by providing, for each wedge element, a corresponding notch produced on the opposite cylinder, associated with the suction gripping member.
- According to a different aspect, the invention relates to a method for producing folded articles from a continuous web material advantageously and preferably in tissue paper, according to independent claim 8.
- Further advantageous characteristics and embodiments of the machine and of the method according to the invention are indicated in the appended claims and described in greater detail hereunder, with reference to an example of embodiment.
- The invention shall be better understood by following the description and accompanying drawing, which shows a non-limiting example of embodiment of the invention. In particular, in the drawing:
- Figure 1 is a plan view of a folding machine incorporating the invention;
- Figure 2 is a front view of the folding cylinders of the machine;
- Figure 3 is a plan view according to III-III in Figure 2;
- Figure 4 is a longitudinal section of one of the folding cylinders;
- Figure 5 is a schematic cross section according to V-V in Figure 2 of the two folding cylinders;
- Figures 6A and 6B are enlargements, in two subsequent positions, of the gripping members of one of the folding cylinders in the point in which the folded web material starts to detach from the folding cylinder;
- Figure 7 is a section according to VII-VII in Figure 2;
- Figure 8 is an enlargement in longitudinal section of the suction area of one of the folding cylinders;
- Figure 9 is a plan detail of the assembly flange of the suction unit; and
- Figure 10 is an enlarged local section according to a plane orthogonal to the axes of rotation of the folding cylinders at the level of the folding area, in the instant in which the crease is formed on the web material.
- With initial reference to Figure 1, the folding machine has a pair of
folding cylinders rotation folding cylinders nip 5. Thefolding cylinder 1 is supported byshanks 1C and 1D (Figure 2) in corresponding supports 7, 9. The foldingcylinder 3 is supported in a similar way by shanks 3C and 3D insupports - The two
folding cylinders toothed wheel 14 which meshes with atoothed wheel 15 keyed onto the shaft of the foldingcylinder 1, and which in turn meshes with a toothed wheel 17 keyed onto the shaft of the foldingcylinder 3. - An eccentric 19 is mounted at the upper end of the
shaft 1C of the foldingcylinder 1, and, by means of a connectingrod 21, provides an alternate movement to a rocker 23 (see Figures 2 and 3). Therocker 23 is keyed onto avertical shaft 25, parallel to the axes of the twofolding cylinders shaped bars 26 which are inserted into correspondingannular grooves 27 of the folding cylinder 1 (see in particular Figure 2). - Hinged to the
rocker 23, at the opposite end to the end at which the connectingrod 21 is hinged, is a further connectingrod 29, the opposite end of which is hinged to abracket 31 keyed onto ashaft 33, parallel to theshaft 25. Integral with theshaft 33 are threebars 35, analogous to thebars 26, which are inserted intocorresponding grooves 37 provided on the foldingcylinder 3. The number ofbars folding cylinders - As can be seen in particular in the cross section in Figures 5 and, limited to the folding
cylinder 3, in the section in Figure 4, a longitudinal seat or cavity, indicated as a whole for both cylinders with 41, is produced inside each of thefolding cylinders cavities 41 are symmetrical to each other as can be seen in particular in Figure 5 and the folding cylinders are in phase with each other so that the cavities are in diametrically opposite positions. - The
cavities 41 emerge on the cylindrical surface of each of the twofolding cylinders cylinder nip 5 between the twofolding cylinders members 43 are symmetrical to each other and only one of them shall be described in detail hereunder with particular reference to Figure 4. - The
gripping member 43 is essentially composed of a block provided with a series of through holes 45 (disposed in the example shown on four rows parallel to the axis of the folding cylinder). The holes emerge on an essentially flat internal orrear surface 47 of theblock 43 and on an essentially cylindricalouter surface 49 positioned flush with the cylindrical surface of the respective folding cylinder 3 (or 1). Thecylindrical surface 49 is interrupted at the level of the grooves 37 (or 27) of thefolding cylinders areas 51, to allow passage of thebars - The
seat 41 of bothcylinders suction duct 53 extending coaxially to the axis of rotation of the respective cylinder and emerging on the upper front surface thereof, where (as shall be described hereunder) it is carried for a certain angle of rotation of the respective cylinder in communication with a suction line. In this way, through theholes 45 of each block 43 a suction is produced - for a predetermined angle - the purpose of which, as shown in greater detail hereunder, is to temporarily retain the web material to be folded along a transverse folding line. - On the
cylindrical front surface 49 of eachblock 43, a cut ornotch 55 is produced (see enlargement in Figure 10), into which awedge 57, produced on aninsert 59 disposed on the opposed cylinder, penetrates. As can be seen in Figure 5, on each of the twofolding cylinders block 43 and theinsert 59 are disposed in diametrically opposed positions, so that during rotation of the twocylinders nip 5 eachnotch 55 of ablock 43 mounted on one of the two cylinders comes to correspond with thewedge 57 of theinsert 59 mounted on the other cylinder. - The machine described hereinbefore operates in the following way. When the folding machine is operating, a web material N, optionally folded longitudinally upstream of the
folding cylinders nip 5 between thefolding cylinders blocks 43 with the relative suction holes 45. - Suction through the
holes 45 is activated, for eachcylinder holes 45 farthest forward with respect to the direction of rotation of therespective cylinder nip 5, so that the web material is drawn and retained on the cylindrical surface of the respective folding cylinder. The plurality of lines of suction holes 45 guarantees efficient retention of the web material when this passes through thenip 5 and moves therebeyond, following the movement of rotation of the cylinder. - Suction through the
holes 45 is maintained until theblock 43 is in an angular position approximately 45-60° farther forward than the position of thenip 5. In this way, the web material N, which advances at essentially the same peripheral speed as thefolding cylinders folding cylinder cylinder 3 is shown). In the position in Figure 5 suction has been interrupted and the folded edge of web material N is detached from thefolding cylinder 3, facilitated in this by the oscillatory movement of thebars 35, the oscillating movement of which is advantageously synchronized with the angular position of thefolding cylinders member 43 associated with thefolding cylinder 3 is indicated with P. - Continuing rotation in opposite directions of the two
folding cylinders suction gripping member 43 is in proximity to the nip 5 suction is activated therethrough to form a fold on the material N, analogous to the fold P produced by thefolding cylinder 3. - With continual rotation of the
folding cylinders gripping members 43, a zigzag fold is obtained on the web material N. This thus forms a pack of material P which is fed (Figure 1) according to the arrow F towards and against a cuttingmember 60 with a cutting edge parallel to the axes ofrotation folding cylinders - To facilitate forming of the folds at the level of the gripping
members 43wedges 57 cooperating with thenotches 55 are provided. These two elements are inserted inside each other at the level of the nip 5 (Figure 10), deforming the web material N between them. This forms a line to facilitate folding, essentially in the form of a crease. To obtain this, it is not necessary for particularly high pressure to be exerted between the twoelements notch 55 to be produced in a removable and replaceable portion of theblock 43. This removable portion can advantageously be made of a yielding material, such as rubber, which may be relatively hard although with greater elasticity than the metal material of which the remaining part of theblock 43 is composed. As can be seen in the drawing, for eachblock 43, thenotch 55 is positioned at the level of the row of suction holes 45 farthest forward with respect to the direction of rotation of therespective folding cylinder - To connect the
suction duct 53 of each of the twofolding cylinders folding cylinder 1 and with 3F for thefolding cylinder 3. This arrangement is shown in detail in Figures 7, 8 and 9 for thefolding cylinder 3. A symmetrical arrangement is provided for thefolding cylinder 1. - By means of a
plate 83 in a material with a low coefficient of friction, ashoe 81 rests on thefront surface 3F of thecylinder 3. Theshoe 81 is connected slidingly to twovertical guide columns 85 clamped inrespective sleeves 87. These are in turn fixed on aflange 89 clamped on a portion 91 of the fixed structure of the machine. Two compression springs 93 (one of which can be seen in Figure 8) stress theshoe 81 against the front surface of therespective folding cylinder - The
flange 89 is shown in a plan view in Figure 9. Two sets of three holes of the fixing screws 97 of thesleeves 87 to retain theguide columns 85, are indicated with 95. As can be seen in Figure 9, theflange 89 is provided with twocurved slots 99. Two screws (one of which is indicated with 101 in Figure 8) are inserted in these slots to fix theflange 89 to the structure 91 of the machine. Thanks to thecurved slots 99, by loosening thescrews 101 the angular position of eachflange 89 can be modified with respect to the axis of therelative folding cylinder respective shoe 81. - The structure of the
shoe 81 is shown in detail in Figures 7 and 8. It has a main body in which a loweredseat 103 is produced, inside which theplate 83 is housed. The main body and theplate 83 of theshoe 81 have a hole with anoblong section 105, which extends parallel to the axis of thefolding cylinder oblong hole 105 is joined to aside hole 107 connected to asuction pipe 109 in turn connected to a fan or other suitable suction member, not shown. Theoblong hole 105 extends angularly, corresponding to the angle of rotation of thecylinder holes 45 of theblock 43. - With this arrangement, when the
folding cylinder suction duct 53 for the entire rotation of the cylinder to which thesuction duct 53 is connected with theoblong hole 105 produced in theshoe 81. The possibility to adjust the angular position of theflange 89 allows adjustment of the angular positions in which suction starts and terminates inside thesuction duct 53. - It is clear from the above description that with the suction system associated with the
folding cylinders wedge 57 cooperating with the notch 55) without the need for mechanical gripping members controlled and operated by particularly complex cam systems, as is the case in conventional devices. - Compared to conventional machines (such as the type described in
WO-A-0162651 - It is understood that the drawing purely shows a possible embodiment of the invention, which may vary in forms and arrangements without however departing from the scope of the concept on which the invention is based. Any reference numerals in the appended claims are provided for the sole purpose of facilitating reading in the light of the description hereinbefore and the attached drawings and do not in any way limit the scope of protection.
