Description

Machine for processing folded printed fabrics

This invention relates to a machine for processing folded printed fabrics.

In particular, but not limited to, the invention may be advantageously applied to a machine or apparatus for steam processing printed cloth.

As is known to us, the steam treatment operation is used to stably fix the dye to the fibers of a fabric by utilizing the combination of the action of the condensed moisture and the action of the ambient heat to cause the dye on the surface of the material and all of the formulated products from the surface layer. Diffusion towards the interior of the fiber, thus fixing the dye and all of the formulated product to the fiber.

One such machine for processing (eg, preparation, steaming, dyeing, conditioning, strengthening, and the like) of folded fabrics generally includes a processing chamber in which an annular (continuous) conveyor belt is supported to support the fabric to be treated An inlet side of one of the chambers (one of which supports and feeds the cloth) is delivered to one of the outlet sides of the processing chamber.

The conveyor belt includes a pair of endless chains that are supported to the chamber and move near the longitudinal wall of the chamber, and the propulsion and return branches of the pair of endless chains are respectively adjacent to the top and bottom of the chamber Extended.

The fabric is foldedly supported within the processing chamber by a plurality of rollers (in the prior art and in the present invention, the ends of the plurality of rollers) coupled to the opposing links of the chain.

In general, one of the conveyor belts of this type is continuously advanced to facilitate the formation of a continuous fold of the fabric on the continuous rod near the inlet side and the formation of the folded fabric in the processing chamber The time required.

An international patent application WO 2004/074567, filed in the name of the Applicant, describes a system for moving a rod and forming a respective fold, wherein the rods are connected to the respective links by a pair of arms, each arm being constrained to one One of the first ends of one of the links is constrained to a second end of one of the corresponding ends of the rod.

This system uses a forming plate on which the arms carrying the rods can slide. As the fabric advances, the arms are turned over, thereby raising the rods and moving the rods from one of the rods to the transport chain in which the rods are moved to the condition in which the rods are placed The chain actively advances one of the conditions on the track above the branch.

The Applicant has noticed that this machine, as well as other similar machines, in which feed is achieved by supporting a chain of folded cloth rods, will be used to process inkjet printed fabrics, or more generally, has previously been subject to a number of digits. There was a problem with the fabric of the printing program.

More specifically, Applicants have demonstrated that even after very slight contact, digitally printed fabrics that have not been subjected to treatment (such as, for example, steam treatment) can transfer the applied dye to other fabrics or other parts of the same fabric. .

Applicants have also observed that an overly narrow fold promotes accidental contact between adjacent portions of the same fold, whereby the dye can be transferred from a folded surface to the surface facing the folded surface (i.e., belonging to the same fold) An inner surface), thus causing problems on some of the cloth parts that are not to be copied.

Accordingly, it is an object of the present invention to prevent undesired duplication after a digital printing process while still employing a reliable lever flipping technique using one of the small spaces.

This and other objects are substantially achieved by a machine for processing a folded printed fabric as in the accompanying technical solution.

Referring to the drawings, a machine for processing a folded printed fabric, in particular, for subjecting a printed cloth to a steam treatment, is generally designated as a component symbol 100.

Figure 1 shows a known machine 100 to which the present invention is applicable.

Thus, the features of machine 100 may be part of the present invention.

Machine 100 (Fig. 1) includes a parallelepiped chamber 1 having longitudinal walls or side walls 2, 3, a top plate 4 and a bottom 5.

At the front, the chamber 1 has a means for entering the fabric to be treated into one of the openings 6; at the rear, the chamber 1 has an opening 7 for withdrawing the treated cloth.

Preferably, the two openings are located in the upper portion of the chamber 1.

The chamber 1 is bounded by a frame 200 which may include the side walls 2, 3, the top plate 4 and the bottom 5 described above.

A cloth support and feed roller 8 is supported at the opening 6 in the chamber 1, and the idle roller 9 supporting the cloth is located close to the outlet opening 7.

Preferably, the two rollers 8, 9 have their horizontal axes perpendicular to the walls 2, 3.

A conveyor belt T is also supported in the chamber 1, and the conveyor belt T includes a pair of endless chains 10, 11.

The chains 10, 11 can be of a conventional type commonly used in the industry.

In the vicinity of the longitudinal wall 2, the chain 10 is supported and towed by the respective chain gears 12, 13, 14, 15 and all of the chain gears 12, 13, 14, 15 have a horizontal axis perpendicular to the wall 2. Preferably, the wheel 12 supported at the vicinity of the opening outlet 7 is directly controlled by a driver M3 to drive the wheel.

Driver M3 and gears 12, 13, 14, 15 form a moving structure that is adapted to facilitate the advancement of chain 10.

The active or advancing upper branch 16 of the chain 10 extends horizontally between the cloth inlet opening 6 and the cloth outlet opening 7, while the return lower branch 17 of the chain 10 is located below the chamber 1 and extends horizontally near the bottom 5 of the chamber 1.

The symbol 18 indicates the upstream front branch of the chain 10; the upper branch 18 extends vertically adjacent the cloth feed roller 8.

The symbol 19 indicates the vertical downstream post branch of the same chain 10.

The chain 11 is substantially identical to the chain 10 and is supported in the same manner adjacent the longitudinal wall 3 of the chamber 1. In particular, the chain 11 is supported by a set of gears (e.g., four gears) that include a drive wheel. Preferably, the above-described kinematic structure also includes all of the elements for facilitating the advancement of the chain 11. For the sake of simplicity, all components associated with the chain 11 have the same component symbols as the components associated with the chain 10.

In the following description, the terms "upstream" and "downstream" should be understood with reference to the direction of movement of the chains 10, 11.

Within the chamber 1, at the proximity of the top plate 4 of the chamber 1, a plurality of horizontal bars 20 are configured to support the folded fabric. The ends of the rods 20 are connected to opposite pairs of chains 10, 11. Specifically (see Figures 2 and 3), each rod 20 has its end supported by a pin 21.

Each pin 21 is freely mounted to a corresponding end 23 of an arm 24. The opposite ends of the arms 24 are free to pivot through a pin 25 into the respective links of one of the chains 10 or 11.

Thus, under normal conditions, each rod 20 is rotatably constrained to the chains 10, 11 and there is a possibility of rotating in two directions about the axis defined by the pin 25.

The rods are held substantially horizontally perpendicular to the walls 2, 3.

The arm 24 is pivoted via a pin 25 to the opposite link of the chains 10, 11; on the opposite side of the links, the arm 24 carries a lever 34 having a crank 35.

In other words, the link is interposed between the arm 24 and the lever 34.

The crank 35 can be, for example, a cylindrical type.

This configuration causes a corresponding rotation of one of the arms 24 to be produced around the same pin 25 when the control lever 34 is rotated about the pin 25. Thus, the lever 20 pivoted to the opposite end of the arm 24 will experience a rotational movement.

During the steaming process, the printed cloth fed into the chamber 1 by the support drum 8 is supported by the rods F running along the branches 16 continuing to advance the chains 10, 11 into a fold F.

The steam treatment procedure is carried out in a manner known per se, and therefore the steam treatment procedure will not be described in detail herein.

At the end of the upper branch 16, the cloth is picked up in a conventional manner and the cloth is unloaded from the steam processing chamber through the opening 7. The rod 20 travels along subsequent branches 19 and 17 of the chains 10, 11 in a suspended condition. In this condition, the rod 20 is raised along the upstream front branch 18 of the same chain 10, 11.

When the upstream branch 18 ends and the active upper branch 16 begins, the condition from which the arms are suspended to one of the chains 10, 11 (first position) is moved to a condition in which the arms are suspended above the propulsion branch 16. (second position).

In this manner, the rod 20 can be folded and positioned onto the upper rail 28 as it reaches the propulsion branch 16.

In particular, the wheel 26 is mounted on a pin 21 of each rod 20 that is intended to engage the respective track 28. The upper track 28 extends over the active branches 16 of the chains 10 and 11.

The distance between each of the upper rails and the respective active branches is shorter than the length of the arms 24; preferably, the distance is about half of the length.

In an embodiment, the wheel 26 is a gear and the track 28 is comprised of respective chains.

Machine 100 includes an inverting structure 300 (Figs. 7-11) for moving rod 20 from a first suspended position to a second suspended position.

1 shows a flipping structure of a known type that continuously rotates all of the rods from the ascending lane 18 to the propulsion branch 16.

In accordance with the present invention, the flip structure 300 is substituted to selectively move the rod 20 from the first position to the second position.

Preferably, the flip structure 300 moves the rod 20 in an alternating manner. In other words, if a given rod is turned from the first position to the second position, the one rod and the next rod will remain in the first position in the active branch 16 immediately before the rod.

In this manner, a wider fold (e.g., twice as wide as a machine-made fold) can be produced, thereby significantly reducing the risk of ink being undesirably transferred from one portion of the cloth to another as the cloth advances.

It should be noted that, in general, selective flipping of the rod 20 may also be achieved depending on a different solution depending on one of the fold widths to be obtained.

Preferably, the flip structure 300 includes at least one first active element 310 positioned in an initial track of the active branch 16 and adapted to flip the rod 20.

The flip structure 300 further includes a first auxiliary component 610 associated with the first active component 310.

The first auxiliary element 610 is adapted to selectively allow the first active element 310 to act on the rod 20 to move the rod 20 from the first position to the second position.

In fact, if the first auxiliary element 610 is not present, the first active element 310 will cause all of the rods 20 to flip from the first position to the second position to result in the results shown in FIG.

Preferably, the first active component 310 includes a shaped panel adapted to cooperate with the rod 20 through a respective lower profile 311.

In fact, the forming plate has a substantially rectangular shape, wherein the lower profile 311 Adapted to cause a lever 20 to move from the first position to the second position.

8 shows a possible embodiment of the first active component 310: the shaped profile 311 can continuously include a first straight track 311a, a curve 311b, a convex portion 311c, and below the first height q1. One of the heights q1 is one of the second straights 311d at the second height q2.

FIG. 9 shows one possible embodiment of the first auxiliary component 610.

Preferably, the first auxiliary element 610 has a respective lower profile 611 through which the first auxiliary element 610 selectively acts on the rod 20.

Preferably, the lower profile 611 has a substantially straight second track 611b at one of the third heights q3 and substantially one of the straight first track 611a and the fourth height q4.

Preferably, the third height q3 is substantially equal to the first height q1.

Preferably, the fourth height q4 is substantially equal to the second height q2.

Preferably, the first track 611a and the second track 611b of the first auxiliary component 611 are connected by a joint 611c.

Preferably, the land 611c engages the first track 611a and the second track 611b along a contour that is substantially straight or otherwise inconspicuously concave as the curve 311b of the first active component 310.

Preferably, a first auxiliary element 610, such as the same forming plate, is provided, the forming plate having the shape shown by way of example in FIG.

From a practical point of view, the first auxiliary component 610 can be similar to the first active component 310 having a portion of the fill curve 311b.

Preferably, the first active component 310 and the first auxiliary component 610 are disposed relative to each other (eg, side by side) such that the connecting portion 611c is located at the curve 311b. In other words, in a side view, the portion of the first auxiliary member 610 delimited by the connecting portion 611c at the bottom closes the gap created by the curve 311b.

As will become more apparent hereinafter, the connecting portion 611c of the first auxiliary element 610 prevents some of the rods 20 (preferably, one of the two) from being bent by the first active element 310 311b and flipped.

Figure 10 is a schematic side view showing a side view from the inside of the machine, wherein we can see in the foreground that the first active element 310 covers almost completely the first, except for the terminal part 611d and the portion corresponding to the connecting portion 611c. Auxiliary element 610.

Preferably, an arm 24 is mounted to at least one end of each of the rods 20; the arm 24 has a first end that is pivoted to one of the corresponding ends of the rod 20, and a link that is pivoted to one of the respective chains 10, 11 One of the second ends.

Preferably, the first active element 310 cooperates with the arm 24 to move the respective rod from the first position to the second position.

In more detail, the first active component 310 intercepts the crank 35 of the lever 20 to move the lever 20 from the first position to the second position.

Suitably, the crank 35 is subdivided into a first group and a second group.

The crank of the first group (Fig. 16a) has a longer longitudinal extension and the crank of the second group (Fig. 16b) has a shorter longitudinal extension.

It should be noted that the longitudinal extension is preferably measured in a direction substantially parallel to one of the rods 20.

In principle, the first active component 310 is adapted to intercept the cranks 35 of the two groups; the first auxiliary component 610 instead ensures that only the cranks of the second group (ie, the shorter cranks) will be intercepted by the first active component 310.

Thus, the rods 20 that cooperate with the cranks of the second group rotate about the respective pins 25 and are positioned on the guides 28 at the transitions from the uphills 18 of the chains 10, 11 to the advancement branches 16.

In particular, the shaped profile 311 of the first active component 310 is adapted to intercept the second group of cranks 35 to cause one of the respective levers 34 to rotate and thus cause one of the respective arms 24 to rotate to facilitate the respective levers 20 from the first Move to one of the second positions.

The first group of cranks will be intercepted by the first auxiliary element 610 instead of by the first active element 310, and the respective rods 20 will not flip, thus remaining in the first position, ie, along The propulsion branch 16 is suspended to the chains 10, 11.

In any event, the first auxiliary element 610 is shaped to dispose an arm associated with the crank of the first group in one of the initial positions of the advancement branch 16 in a substantially horizontal position so as not to interfere with the folding forming procedure.

Preferably, the first auxiliary element 610 is positioned at a distance from one of the respective chains 10 to intercept the first group of cranks 35 and not to intercept the second group of cranks 35.

In effect, the first active component 310 has a flat extension that is substantially parallel to the flat extension of the first auxiliary component 610; the planar extensions are preferably substantially parallel to the chains 10, 11 and substantially orthogonal to the crank 35 longitudinal extension.

Thus, the second group of cranks 35 (which are shorter) will not be able to reach the first auxiliary element 610 and will only be guided by the first active element 310; conversely, the first group of cranks 35 (which are longer) will Reaching the first auxiliary element 610 will prevent the cranks from rotating and flipping their respective levers.

Preferably, the first active component 310 and the first auxiliary component 610 are substantially integrated with each other.

Preferably, the flip structure 300 also includes a first moving member 320 that acts on the first active component 310 to cause the first active component 310 to travel back and forth (specifically, in one of the directions of advancement substantially parallel to the branch 16) Direction) alternately moves.

For example, the first moving member 320 (FIG. 11) can include an electric motor 321 associated with a cam 322 that is appropriately sized to move the first active between the travel proximal position and the travel distal position. Element 310 and first auxiliary element 610.

It should be noted that, for simplicity, FIG. 11 shows only the first active component 310; as previously described, the first active component 310 is preferably disposed immediately adjacent to the first auxiliary component 610 (outside) and with the first auxiliary component 610 integration.

As shown schematically in Figures 14a-14d, the first active element 310 is initially located in a stroke distal position (on the left side of the drawing).

In a schematic cross-sectional view, black circles indicate the first group of cranks 35, and (hollow) white circles indicate one of the second group of cranks 35.

The crank of the second group travels following the contour of the first active element 310, as shown in Figures 14a-14f.

When the crank of the second group is located at the second straight 311d of the lower contour 311 of the first active component 310, the first moving member 320 will move the first active component 310 toward a proximal end position to enable the first group The set of cranks 35 are guided all the way to the guides 29a, as shown in Figure 14f.

Next, the first active element 310 will be returned to the distal end position of the stroke to intercept a crank below the second group.

The black circle instead travels following the contour of the first auxiliary element 610, as shown in Figures 15a through 15f.

As previously mentioned, due to the connecting portion 611c, the cranks do not enter the curve 311b of the first active member 310, and their respective levers do not flip.

After following the contour of the first auxiliary element 610, the crank of the first group towed by the advancement branch 16 will be by using the available intermediate space H between the end of the second straight 611b and the guide 29b (Fig. 15c) The terminal part 611d following the same first auxiliary element 610 travels to Fig. 15d).

Subsequently (Fig. 15e to Fig. 15f), the first auxiliary element 610 integrated with the first active element 310 will be moved from the stroke distal position in which the first auxiliary element 610 is initially positioned to the proximal end position of the stroke, thus the first group The crank of the set moves all the way to the guide 29b.

It should be noted that the position of the first auxiliary component 610 shown in Figures 15a through 15f corresponds to the position of the first active component 310 shown in Figures 14a through 14f.

Preferably, the flip structure 300 further includes a first guiding element 330 that is substantially integrated with the frame 200 and has an arched profile.

The first guiding element 330 is substantially located on the upgoing track 18 and the propulsion branch 16 of the chain 10, In the transition zone between.

The first guiding element 330 performs the task of rotating the rod 20 about the pin 25 to direct the crank 35 such that the lever 34 and the arm 24 will self-contain one of the substantially vertically oriented horizontal configurations presented in the ascending track 18. .

The contour of the first guiding element 330 is substantially adjacent to the contour of the first active element 310 and, in particular, adjacent to the first straight 311a.

Preferably, the first guiding element 330 is located at the same distance from the chain 10, 11 as the first active element 310. In this manner, before all of the cranks 35 (both the first group of cranks and the second group of cranks) are selectively intercepted by the first active component 310 and the first auxiliary component 610, the first guiding component 330 can be Guide the cranks.

In fact, at the upper end of the front branch 18, the crank 35 of the lever 34 will first encounter the contour of the first guiding element 330 and then the contour 311 of the first active element 310. The combination of the action of the first guiding element 330 and the first active element 310 with the advancement of the chain will prevent the rod 20 from remaining in the suspension condition presented in the vertical track 18 and will force the arm 24 to rotate to self-suspend the rod 20. Move to the suspended configuration.

The above applies to the lever associated with the crank of the second group; for the lever 20 associated with the crank 35 of the first group, the first active element 310 will be inactive: the respective crank will follow the first guiding element 330 The arched contour travels, and then the cranks will follow the contour 611 below the first auxiliary element 610 instead of being flipped by the shaped profile 311 of the first active element 310; subsequently, the rod will be by gravity Return to the suspended position to remain in this position along the entire advancement branch 16.

Advantageously, when the cranks 35 of the second group undergo a rotation that causes the respective levers 20 to flip, the motion structure imparts an acceleration (a so-called "pull") to the chains 10, 11 to facilitate the formation of the fold and prevent the cloth from being on the pole. slide.

The timing of the accelerations can be determined to vary depending on the angular position of a reference axis (e.g., the axis of the drive M3 described above).

It should be noted that, in practice, the lever 20 associated with the crank of the first group does not perform the function in the machine thus designed: the lever is only deactivated without being physically removed and still available for future operation, There is a need/requirement to make a narrower fold.

In order for the lever associated with the crank of the first group to operate again, displacement of the first auxiliary component 610 will be sufficient in such a manner that the first auxiliary component 610 no longer intercepts one of the cranks of the first group. For example, the first auxiliary element 610 can be translated away from the chain 11. Preferably, the first active element 310 is also translated integrally; the first active element 310 will intercept all of the cranks (ie, the first group of cranks and the second group of cranks) such that all of the rods will be flipped.

It is contemplated that the first auxiliary component 610 (and preferably the first active component 310) can be displaced by a respective actuator (e.g., a hydraulic or electromechanical actuator) based on a manual or automatic command.

Preferably, this displacement occurs in a direction orthogonal to one of the displacements applied by the first moving member 320.

It should be noted that the above description is preferably only for one end of each rod 20. By way of example only, with reference to the schematic top view of FIG. 7, the description is preferably only with respect to the right end of each of the rods 20, ie, the end of the first active element 310.

Preferably, the flip structure 300 can include a second active element 340 that operates at the opposite end of the rod 20.

The shape and position of the second active component 340 is completely similar to the shape and position of the first active component 310.

The second active element 340 acts on the opposite end of the rod (eg, the left end, still referring to FIG. 7), thereby intercepting the respective cranks 35 and causing the levers 34 and arms 24 to rotate about the pin 25, much as with reference to the first active element 310 description.

The second active component 340 is positioned and structurally designed in a manner that causes the same lever to be flipped by the first active component 310.

In fact, the crank 35 has one of a radial/longitudinal axis relative to one of the machines 100 substantially Symmetrical design. The first active device 310 and the second active device 340 are symmetrically arranged with respect to the axis. Therefore, the first active component 310 and the second active component 340 will intercept the cranks belonging to the second group, however, do not interact with the cranks of the first group, so that the poles 20 associated with the cranks of the first group will remain In the hanging position.

Advantageously, the second active element 340 is associated with a second auxiliary element 620.

Preferably, the second auxiliary element 620 has a shape that is substantially the same as the shape of the first auxiliary element 610.

The second auxiliary element 620 ensures that only the second group of cranks will be intercepted by the second active element 340 and that only the second group of cranks will be rotated.

The cranks of the first group will travel along the contour of the second auxiliary element 620 such that the respective levers do not flip.

Preferably, the second active component 340 and the second auxiliary component 620 are symmetric with respect to the first active component 310 and the first auxiliary component 610 with respect to the radial/longitudinal axis of the machine 100.

Preferably, the flip structure 300 further includes a second moving member 350.

Preferably, the structure and operation of the second moving member 350 are the same as the structure and operation of the first moving member 320.

The second moving member 350 imparts a motion to the second active element 340 and preferably to the second auxiliary element 620, the motion being similar to being given to the first active element 310 by the first moving member 320 and preferably to the first auxiliary element The movement of 610.

Furthermore, the second active element 340 and the second auxiliary element 620 can be preferably displaced in a direction orthogonal to the longitudinal extension of the active branch 16 and parallel to one of the bottom plates 5 of the machine 100 such that the second auxiliary element 620 does not intercept Any cranks, and all cranks are intercepted by the second active element 340 to flip all the bars.

The motion imparted by the first moving member 320 and the second moving member 350 is schematically shown in Figs. 14a to 14f and Figs. 15a to 15f.

The first moving member 320 and the second moving member 350 operate in a synchronous manner to phase The first active component 310 (and preferably the first auxiliary component 610) and the second active component 340 (and preferably the second auxiliary component 620) are simultaneously applied to the same motion.

In this manner, machine 100 can act on both ends of each rod in a substantially simultaneous manner, thereby causing the rod to flip or continue its stroke in suspension conditions.

Advantageously, machine 100 further includes at least one of processing units 400 associated with first motion structures M3, 12, 13, 14, 15 and first moving member 320 to cause them to be synchronized.

Preferably, the processing unit 400 is also associated with the second moving member 340 to synchronize the second moving member 340 with the moving structures M3, 12, 13, 14, 15 and the first moving member 320.

In particular, processing unit 400 can be input with a parameter that represents the current angular position of a crankshaft (e.g., the axis of drive M3 that causes the chain 10, 11 to advance) as a reference.

Accordingly, processing unit 400 can determine when it is necessary to move the first (and possibly second) moving member and thus the first (and possibly second) active element by comparing the parameter to a previously stored reference.

In particular, based on the predetermined angular position of the reference axis, the processing unit 400 will command the first (and possibly second) moving member to move between the distal end position and the proximal end position of the stroke according to the above description (and possibly 2) Active components.

To this end, the processing unit 400 transmits one or more activation signals S to the first moving member 320 and possibly the second moving member 340.

In an embodiment, processing unit 400 first performs one step of aligning the various motors/drivers (eg, drive M3, first moving member 320, and possibly second moving member 340) controlled thereby. In this way, the machine can begin to operate correctly and its various components can be moved in synchrony as appropriate.

If any problems or malfunctions are detected (eg, an improper positioning bar), processing unit 400 will stop the machine and perform a new alignment operation to allow the machine to properly resume its operation.

Preferably, processing unit 400 can be structurally designed to manage one of the entire machine 100 PLCs.

Advantageously, the flip structure 300 can include a second guide element 360 that is similar to the first guide element 330 that is positioned upstream of the second active element 340 and the second auxiliary element 620.

Preferably, the cranks of the first group and the cranks of the second group are alternated.

In other words, each rod 20 is associated with a pair of cranks 35, each crank itself being associated with a respective end of one of the rods; both of these cranks 35 belonging to the first group or the second group. If the crank of the first group is mounted at the end of a given rod, the crank of the second group will be mounted at the end of the immediately adjacent rod and at the end of the next rod.

Similarly, if the crank of the second group is mounted at the end of a given rod, the crank of the first group will be mounted at the end of the immediately adjacent rod and at the end of the next rod.

In this way, one of the two rods will be involved in the folding formation procedure, while the other rods will remain in the suspension condition, ie, ready for use.

In accordance with a variation of the present invention, the flip structure 300 can selectively flip the rod 20 without moving the first active element 310, the first auxiliary element 610 (and possibly the second active element 340 and the second auxiliary element 620).

This variation is shown in Figures 21a-21b, 22a-22b, 23a-23f, 24a-24f, 25a-25b, 26a-26b, 27-30.

In this variation, the first active component 310, the first auxiliary component 610, and preferably the second active component 340 and the second auxiliary component 620 are substantially fixed, i.e., integrated with the chassis 200 of the machine 100. The location of the components is the aforementioned distal stroke.

The machine 100 includes a main guide G1 disposed adjacent the active branch 16 and adapted to engage the crank 35 such that the respective lever 20 remains in the second position along the active branch 16 (i.e., flipped).

In fact, the main guide G1 (which can replace the aforementioned guides 29a, 29b) can be formed as a self-side The walls 2, 3 extend horizontally as one of the cantilevers.

The flip structure 300 further includes a structural design to selectively allow the crank 35 to reach one of the first guides 370 of the main guide G1.

In more detail, the first guiding device 370 is designed in such a manner that the gap between the first active component 310 and the main guiding member G1 is closed: when the first guiding device 370 closes the gap, the crank of the second group 35 can follow the contour of the same first guiding device 370 and reach the main guide G1; when the first guiding device 370 opens the gap, the first group of cranks 35 "fall" into the gap (due to the respective The weight of the rods) and the respective rods 20 are maintained in suspension conditions to maintain this condition along the active branches 16.

It should be noted that in the previously disclosed variations, the gap between the first active element 310 and the guide 29a is dynamically filled by the movement of the first active element 310 and the first auxiliary element 610 as needed.

In this variant, at least the first guiding device 370 is envisaged.

21a-21b schematically show perspective views of the first guiding device 370.

Preferably, the first guiding device 370 includes a guiding portion 371 adapted to intercept the first group of cranks 35.

Preferably, the first guiding means 370 includes a closed portion 372 that selectively closes the gap between the first active element 310 and the main guide G1 and allows the second group of cranks 35 to reach the same main guide G1.

Preferably, the first guiding device 370 is pivotally mounted (preferably with its first end 370a) mounted to the frame 200, in particular, to the side walls 2, 3.

Preferably, the first guiding device 370 includes a reset element 373 adapted to return the first guiding device 370 to an initial position after the first guiding device 370 has been moved by one of the first groups of cranks 35.

Preferably, the reset element 373 acts on a second end 370b of the first guide 370 opposite the first end 370a.

For example, the reset element 373 can be changed to a resilient element (e.g., a spring, as shown schematically in Figures 21a-21b).

As an alternative, the reset element 373 can be made a push element (e.g., a pneumatic push element).

Alternatively or in addition to the above, the reset element 373 can include a weight suspended from the first end 370a to facilitate clockwise rotation of the first guide element 370 (in the view of Figure 21a).

Preferably, the first guiding device 370 is configured such that the closing portion 372 closes the gap between the first active element 310 and the main guide G1.

Preferably, the first guiding device 370 is substantially disposed at a lower level than the first active component 310 and the main guiding member G1.

Preferably, the first guiding device 370 is positioned to intercept the first group and the second when the first group and the second group of cranks 35 slide along the lower edge of the first active element 310 or the first auxiliary element 610 Group crank 35.

Preferably, the first guiding means 370 are disposed at a distance from one of the respective chains 11 such that the guiding portion 371 intercepts the first group of cranks 35 and does not intercept the second group of cranks 35.

In summary, the first guide 370 essentially becomes a pivoting lever that includes portions having different widths (measured in a direction parallel to one of the rods 20) associated with a reset element. The portions having different widths are the guiding portion 371 and the closing portion 732.

Figure 25a schematically shows one of the first group of cranks 35a, one of the second group of cranks 35b, the first active element 310, the first auxiliary element 610, the chain 11, the first guiding device 370 and the main guide G1. In this configuration, the first group of cranks 35a are sufficiently long to be intercepted by the first auxiliary element 610 and the leading portion 371 of the first guiding element 370. Accordingly, the respective levers are not turned over. Conversely, the second group of cranks 35b are short enough not to be intercepted by the first auxiliary component and thus cooperate with the first active component 310 and the closed portion 372 of the first guiding component 370 To reach the main guide G1. Accordingly, the respective levers are turned over and maintained in the suspended position.

Preferably, the first guiding element 370 is substantially integrated with the first active element 310 and the first auxiliary element 610.

Preferably, the first guiding means 370 is generally located in the position schematically represented in Figure 24a. In particular, the first guiding device 370 is maintained in this position by the reset element 373.

When one of the cranks 35 of the first group towed by the chain 11 reaches the first guiding device 370 (Figs. 24b to 24c), the first guiding device 370 is intercepted by the guiding portion 371 (Fig. 24d). As the crank continues forward, the first guide 370 rotates counterclockwise (Fig. 24e) and opens the path toward the gap for the same crank. The cranks of the first group enter the gap under the weight of the respective rods. The cranks, which are always towed by the chain 11, and the respective rods are advanced along the active branches 16 in the suspension condition, rather than cooperating to form any folds.

When the first guiding device 370 no longer experiences the crank of the first group, the first guiding device 370 is returned to the initial position by the reset element 373 (Fig. 24f).

When one of the cranks 35 of the second group dragged by the chain 11 reaches the first guiding device 370 (Figs. 23a to 23d), the crank 35 is not intercepted by the guiding portion 371 because the guiding portion 371 is disposed at a distance from each other. One of the chains is too long. Thus, the crank of the second group advances until it reaches the closed portion 372 (Fig. 23e), which allows the same crank to reach the main guide G1 (Fig. 23f).

Accordingly, in this case, the first guiding device 370 is not displaced.

Due to the constraint imposed by the main guide G1 to the respective cranks and the constraint applied by the chain 11 to the pins 25, the rods 20 associated with the cranks 35 of the second group remain in the flip condition.

It should be noted that the above disclosure relates only to one side of the machine 100, wherein only one end of the rod 20 is involved. Advantageously, it is contemplated that a similar structure is also provided at the opposite side of the machine, the similar structure comprising a guide member G1 and a second auxiliary guide G1 and a second guide 370 that are completely analogous to the above. Guide device 380.

Figure 26a schematically shows one of the cranks 35a of the first group, one of the cranks of the second group 35b, a second active component 340, a second auxiliary component 620, a chain 10, a second guiding device 380, and an auxiliary guiding member G2. The same statement presented above with respect to Figure 25a also applies to Figure 25a.

Figure 26b shows a different configuration of the same element, similar to the configuration shown in Figure 25b, in which all the bars (the bars associated with the cranks 35a of the first group and the cranks 35b of the second group are associated) Both of them are flipped.

Preferably, the second guiding element 380 is substantially integrated with the second active element 340 and the second auxiliary element 620.

It should be noted that, with respect to the lateral displacement of the first active component 310, the first auxiliary component 610, the second active component 340, and the second auxiliary component 620, FIGS. 25a-25b and 26a-26b may also be applied to the machine 100. Previous variants.

22a-22b schematically show perspective views of a second guide 380.

It should also be noted that the main guide G1 and preferably the auxiliary guide G2 can also be advantageously used in the previous variant to replace the guides 29a, 29b.

As has been disclosed in the previous variations, the operation of the machine can be modified and all rods can be made by displacing the first active element 310 and the first auxiliary element 610 in a direction substantially orthogonal to one of the longitudinal extensions of the active branch 16. Flip.

Figure 25a schematically shows the configuration of the elements when only the lever associated with the crank 35b of the second group is flipped.

Figure 25b schematically shows the configuration of the elements when all the bars are turned over: the first auxiliary element 610 no longer intercepts any cranks, while the first active element 310 intercepts all the cranks, ie the first group of cranks and the second group Both cranks.

The same applies to the second active component 340 and the second auxiliary component 620 shown in Figures 26a-26b.

Referring to Figures 4-6, the operation of the machine 100 during formation of the fold will be described below, wherein the first active element 310 can intercept all of the cranks 35.

However, it should be noted that in accordance with the present invention, the rod is selectively (preferably based on a replacement) Flip). The following description of the description with reference to Figures 4 to 6 is only intended to illustrate in detail the flipping motion of the rod 20 and the formation of the respective folds.

When the conveyor belt T is in motion, the crank 35 of the upright rod 20a first contacts the arched profile of the guiding element 330; a rod 20b is located in the immediate vicinity of the upper rail 28 and in this position by the second straight of the active element 310 311d support. In the space between the drum 8 and the rod 20b, the pre-humidification nozzle 33 prevents the cloth from sliding and forms an open fold Fi, which refers to the running direction of the conveyor belt T, and the front edge 60 of the open fold Fi contacts the rod 20c, the edge being located relative to Downstream of the rod 20c. The symbol 20a indicates the rod following the above rod 20b.

This forward motion simultaneously causes the movement of the rod 20a through the sliding action of the corresponding crank 35 along the guiding element 330 and the interaction of the corresponding crank 35 with the first active element 310 (and possibly with the second active element 340). One of the pins 25 (where the arms 24 of the pins 25 are attached to the chains 10, 11) moves substantially in a single pendulum manner. The rod 20c is pushed forward to open the folded front edge 60, which is in contact with the front edge 60 on the back (unprinted portion) of the cloth. When the crank 35 of the rod 20c continues to advance along the arcuate profile of the guiding element 330 and interacts with the first active element 310 (and possibly with the second active element 340), the crank 35 of the rod 20c causes the rod to begin to rotate upwardly, thereby causing the rod to begin to rotate upwardly The rod is brought into position 20b, i.e., substantially at the same level as the track 28.

When the movement ends, although the previously considered folded Fi will be closed and supported by the rods 20b to 20d (which will now occupy the initial position of the active branch 16 of the conveyor T), a new open fold will be formed. Between the drum 8 and the rod 20c, the folding is repeated to form a loop.

Due to the cooperation between the first active element 310 and the first auxiliary element 610, the operation of the machine according to the invention will be similar to that described above, the only difference being that not all of the rods 20 will be flipped (preferably As previously mentioned, one of the two rods is flipped) and thus the fold will only be formed by the flip lever.

12 and 13a to 13c are shown to illustrate the operation of the machine according to the present invention, wherein The swivel structure 300 operates as described above.

The symbol 20' indicates the rod associated with the crank of the first group, i.e., the rod that will not be flipped and will remain downstream of the flip structure 300 in a position suspended from the chain.

The component symbol 20" indicates the lever associated with the crank of the second group that is not flipped while traveling in accordance with the contour of the first active component 310.

In particular, Figure 13b shows how the first group of cranks associated with the rod 20' will "fall" into the available free space downstream of the first active element 310, since the first active element 310 will be located In the distal position of the stroke.

Figure 13c shows how the second group of cranks associated with the rod 20" will "follow" the first active element 310 toward the guide 29a after having been rotated by the lower contour of the first active element 310; in fact, The first active element 310 will be moved towards the beginning of the guide 29a, i.e., into its proximal end position so that no gaps will be available for the crank and will maintain the rod 20" in the arriving position.

It should be noted that, as previously mentioned, the machine 100 in accordance with the present invention may be modified to have all of the bars 20 (i.e., the bars associated with the cranks of the first group and the bars associated with the cranks of the second group) )) flipped.

To this end, the first auxiliary element 610 is removed (or at least the first auxiliary element 610 is moved into an inoperative position); preferably, the second auxiliary element 620 is also removed, or at least the second auxiliary element 620 is moved Into a non-operating position.

For a machine thus designed, it will no longer be necessary to move the first active component 310 (and the second active component 340) as described above.

The first active component 310 (and preferably the second active component 340) can be moved by a respective actuator to impart an acceleration to the rotation of the crank. This promotes the formation of the fold and also avoids the need to give the above-mentioned "pull" to the chains 10, 11.

The present invention provides significant advantages.

First of all, the machine according to the invention prevents formation of defects after the digital printing process To copy.

The same machine can also be implemented with reliable and small lever tilting technology.

It should be noted that the above described lever flipping mechanism may be advantageously employed, which not only does not require selective flipping of the lever, but also ensures that the feed chain will move at a substantially constant speed.

In this way, the chain can be prevented from being subjected to a sudden acceleration ("pull") of the rod for the force required to turn it over.

The possibility of folding fluctuations can be reduced by moving the chain at a substantially constant speed, and thus the likelihood that the prints made on the different folds can contact each other (and thereby destroy each other) can be reduced.

Preferably, the first actuator (320) is adapted to place the first active element (310) into a position in which the first active element (310) intercepts the crank (35) and then The first active element (310) moves the first active element (310) in a manner that drags the crank (35) and facilitates rotational movement of the respective rod (20).

Preferably, the second moving structure (300) further comprises a guiding element (330) substantially integrated with the frame (200) and having an ascending channel substantially located on one of the chains (10, 11) ( 18) One of the arched contours at one of the upper ends.

Preferably, the machine (1) further includes a processing unit (400) associated with the first motion structure (M3, 12, 13, 14, 15) and the second motion structure (300) such that the A moving structure (M3, 12, 13, 14, 15) and the second moving structure (300) are synchronized.

Preferably, the processing unit (400) is structurally designed to transmit one or more enable signals (S) to the second motion structure (300), the one or more enable signals (S) being based on the first The position of the moving structure changes.

Preferably, after receiving at least one of the enable signals (S), the first actuator (320) implements the first active component (310) to the first active component (310) intercepting the crank (35) a first movement of one of the positions, and a second movement of one of the first active elements (310) to cause the respective arm (24) to rotate and thereby cause the corresponding rod (20) to move.

Preferably, the second moving structure (300) is structurally designed to move the rods (20) from the first position to the second position as the chains (10, 11) are advanced.

Preferably, a respective arm is pivoted to each end of the rod (20), and then the opposite ends of the respective arms are pivoted to one of the respective links of the chains (10, 11), wherein The first active component (310) cooperates with one of the arms, the machine further comprising a third moving structure (500) that is at least partially movable relative to the frame (200) and opposite the other arm An action is applied to facilitate movement of the rod from the first position to the second position.

The general structure of the machine according to this embodiment is similar to that shown in Figures 1 to 6; the features described above with reference to these figures may also be included in the machine according to this second embodiment.

In this second embodiment, the first auxiliary element 610 and the second auxiliary element 620 are not used.

Therefore, obtained by the second motion structure 300 and preferably the third motion structure 500 The pole is flipped.

Preferably, the second motion structure 300 is positioned and operated in the terminal portion of the upgoing track 18 and the initial track of the propulsion branch 16.

Preferably, the second motion structure 300 is positioned and operated at the gear 15.

Preferably, the first active component 310 (Fig. 18) has a contour 311 that is adapted to cooperate with the arm 24.

In the preferred embodiment, the contoured profile 311 is adapted to intercept the crank 35 to cause one of the levers 34 to rotate and thereby cause one of the arms 24 to rotate, thus facilitating movement of the lever 20 from the first position to the second position.

Preferably, the shaped profile 311 can be a lower profile of one of the first active components 310. For example, the first active component 310 can be implemented as a suitably shaped plate.

The forming profile 311 may continuously include a first straight track 311a, a curve 311b, a convex portion 311c, and a second one lower than the second height q2 at the first height q1. Straight 311d.

Under the action of the first actuator 320, the first active element 310 is first positioned (Figs. 18a, 18b) in such a manner that the first active element 310 will intercept the crank 35. In fact, the crank 35 will be intercepted by the curve 311b.

Subsequently, the first actuator 320 will facilitate the first initiative in a manner that causes the first active element 310 to drag the crank 35 and will facilitate the rotational movement of the rod 20 through the mechanism including the control rod 34, the pin 25 and the arm 24. Element 310 acts (Fig. 19a, 19b).

Preferably, the motion of the first active component 310 is an alternating linear motion, i.e., a so-called reciprocating motion.

The position at which the first active element 310 intercepts the crank 35 corresponds to one of the linear proximal positions of the linear track (Figs. 18a, 18b). Movement toward the distal end position of the stroke (Figs. 19a, 19b) causes the rod 20 to move as described above.

The movement of the first active component 310 after it has intercepted the crank 35 occurs at the advancement point The direction of advancement of the branch 16 is in the opposite direction.

The combined movement of the active element 310 (which drags the crank 35 to the left side of the drawing) and the chains 10, 11 (which drag the pin 25 to the right of the figure) will cause the rod 20 to rotate about the pin 25.

In more detail, the following motion steps can be generally defined:

1. The crank 35 dragged by the chains 10, 11 follows the first straight 311a (Figs. 20a to 20d);

2. Next, the crank 35 is intercepted by the curve 311b (Fig. 20e).

3. Moving the first active element 310 from the stroke proximal position X1 to the stroke distal position X2, and the crank 35 constrained to the curve 311b undergoes a sudden acceleration opposite to the forward movement of the propulsion branch 16 of the chain ( Figure 20f).

4. The crank 35 continues to be dragged by the chains 10, 11 to follow the convex portion 311c (Fig. 20g, Fig. 10h).

5. The crank 35 continues to be dragged by the chains 10, 11 to follow the second straight 311d (Fig. 20i).

Preferably, the first height q1 of the first straight track 311a is substantially equal to the height of the pin 25. In fact, during step 1, the lever 34 and the arm 24 are substantially horizontal (or only slightly inclined anyway).

As previously mentioned, the second height q2 of the second straight track is preferably lower than the first height q1 and thus lower than the height of the pin 25. During step 5, the lever 34 and arm 24 are tilted such that the lever 20 is above the advancement branch 16, in particular, high enough to position the wheel 26 onto the guide 28.

Preferably, at the beginning of step 1, the first active component 310 is located in the distal end position X2 of the stroke that is reached at the end of the motion of the previous lever (Fig. 20a). When the crank 35 will reach the curve 311b (Fig. 20b), the first actuator 320 moves the first active element 310 into the stroke proximal position X1 (Fig. 20c). Therefore, the crank 35 will travel again following the first straight 311a (Figs. 20c, 20d) until the crank 35 is intercepted by the curve 311b (step 2, Fig. 20e).

Preferably, step 3 occurs in such a manner that the movement of the first active element 310 allows the rod 20 to rise above its minimum height relative to the propulsion branch 16.

As shown schematically in Figure 19c, the rotation of the giving rod 20 is opposite to the general direction of advancement (clockwise) of the chains 10, 11 (counterclockwise).

In particular, the arrows A1, A2, A3 indicate the direction of movement of the first active element 310, the direction of movement of the chains 10, 11, and the direction of rotation of the arm 24, the direction of rotation of the arm 24 defining the rotation of the rod 20 about the axis of the pin 25. motion.

It should be noted that the dimensional ratios of the various components shown in Figure 19c do not correspond to actual scales: the ratios have been changed to merely characterize the components shown.

Preferably, the second flip structure 300 further includes a guide member 330 that is substantially integrated with the frame 200 and has an arched profile.

The guiding element 330 is situated substantially in the transition region between the upcomer 18 of the chain 10, 11 and the advancement branch 16.

The guiding element 330 performs the task of initiating rotation of the rod 20 about the pin 25 to cause the lever 35 to be guided in such a manner that the lever 34 and the arm 24 will themselves exhibit one of the substantially vertically oriented horizontal configurations present in the ascending channel 18.

When the first active component 310 is in the distal end position X2, the contour of the guiding element 330 is substantially adjacent to the first straight 311a of the first active component 310.

In fact, near the upper end of the front branch 18, the crank 35 of the lever 34 will first encounter the contour of the guiding element 330 and then the contoured profile 311 of the first active element 310. The combination of the action of the first guiding element 330 and the first active element 310 with the advancement of the chain will prevent the rod 20 from remaining in the suspension condition presented in the vertical track 18 and will force the arm 24 to rotate to self-suspend the rod 20. Move to the suspended configuration.

The first actuator 320 can include an electric motor 321 associated with a cam 322 that is appropriately sized to move the first active element 310 between the stroke proximal position X1 and the stroke distal position X2.

It should be noted that the above description preferably applies only to the second motion structure 300 that, through its own first active element 310, acts on one of the arms 24 that are constrained to one of the first ends of the rod 20 (borrowed) By the respective control lever 34 and crank 35). Machine 100 advantageously includes a third motion structure 500 that is substantially similar to one of second motion structures 300. The third kinematic structure 500 is at least partially movable relative to the frame 200 and acts on an arm that is itself constrained to the second end of the rod 20.

The third motion structure 500 operates in the same manner as the second motion structure 300 and is synchronized with the second motion structure 300 to collectively facilitate rotational movement of the rod 20 about the pin 25 and move the rod 20 from the first position to the second position.

Preferably, the third moving structure 500 comprises: a. a second active element 510 movable relative to the frame 200 and acting on the arm 24 pivoting to the second end of the rod 20; b. A second actuator 520 is associated with the second active component 510 to move the second active component 510.

The structure and shape of the second active component 510 is completely similar to the structure and shape of the first active component 310.

The motion imparted to the second active component 510 is completely similar to the motion imparted to the first active component 310.

The second actuator 320 can be implemented in the same manner as the first actuator 520.

The third motion structure 500 can also have a guiding element 530 that is completely similar to the guiding element 330 of the second moving structure 300.

In short, when it is desired to rotate a rod 20 about the pin 25 such that it can be placed onto the guide 28, the second moving structure 300 and the third moving structure 500 will pivot to one of the corresponding ends of the rod 20. The respective arms 24 act to effect the described movement.

Advantageously, the machine 100 further includes a processing unit 400 associated with at least the first motion structures M3, 12, 13, 14, 15 and the second motion structure 300 to cause the first motion The structures M3, 12, 13, 14, 15 and the second motion structure 300 are synchronized.

Preferably, the processing unit 400 is also associated with the third motion structure 500 to synchronize the third motion structure 500 with the first motion structure and the second motion structure.

In particular, processing unit 400 can be input with a parameter that represents the current angular position of a crankshaft (e.g., the axis of drive M3 that causes the chain 10, 11 to advance) as a reference.

Processing unit 400 can determine when it is necessary to move the first (and possibly second) active component by comparing the parameter to a previously stored reference.

In particular, based on the predetermined angular position of the reference axis, the processing unit 400 will command the first (and possibly second) actuator to move the first (and possibly second) active element into the proximal end position of the stroke, and then The same active element moves into the distal position of the stroke.

To this end, processing unit 400 transmits one or more enable signals S to a second (and possibly third) motion structure.

In an embodiment, processing unit 400 initially performs one of the steps of aligning the various motors/drivers (eg, drive M3, first actuator 320, and possibly second actuator 520) controlled thereby. In this way, the machine can begin to operate correctly and its various components can be moved in synchrony as appropriate.

If any problems or malfunctions are detected (eg, an improper positioning bar), processing unit 400 will stop the machine and perform a new alignment operation to allow the machine to properly resume its operation.

Preferably, processing unit 400 can be structurally designed to manage one of the entire machine 100 PLCs.
