Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention involves creating accordion-like folds in a fabric to form a number of parallel series flaps that taper toward one edge in width; It relates to a machine that performs so-called sunflower-shaped pleating.

BACKGROUND TECHNOLOGY In order to produce the pleated fabric described above, there is provided a conveyor arm that swings at a constant angle and is designed to give an intermittent forward movement to the fabric to be pleated, and the arm moves the flaps or pleats. Pleating machines have previously been developed with movable contact walls that form pleating walls.

In effect, the contact wall acts as an anvil for pleating the fabric at the forward end of the arm's forward range of motion, and then rises and transfers so that the formed pleats move toward the guide member of the pleated fabric. It is configured to allow movement to.

Although this prior art technique appears to work well on the surface, it has been found to be inadequate for providing pleated fabrics of acceptable quality. That is, upward movement of the contact wall has a tendency to drag the pleated fabric therealong if the arm is held in a position near the wall. In the opposite case, the position of the folded flap will be indeterminate and the edges of the fold will be formed incorrectly. Moreover, when the wall returns to its starting position from above, it often interferes with the just-formed flap and pinches it, or at least shifts it into an incorrect position.

In the case of very soft fabrics, the arm cannot move it precisely in a given arcuate direction, and the portion of fabric caught between the arm and the contact wall does not follow a straight path, but rather It tends to approach the contact wall following an arcuate path.

Finally, many of the components of this prior art machine have complex structures that cannot be easily adapted to the need to change the depth or slope of the pleats.

For these reasons, pleated fabrics with so-called "sunflower" folds are produced mostly by hand, by inserting the fabric between a pair of pleated paperboards, then compressing the paperboards into an accordion shape, and The fabric is treated by placing it in a suitable device, applying a load and heat treating it to set the fabric in a pleated state.

However, this technique is unsatisfactory in terms of time and effort, and such empirical methods are practically unacceptable in mass production.

Object and Structure of the Invention The first object of the present invention is to provide a pleating machine capable of forming a fabric having sunflower-shaped folds quickly, economically, and in a satisfactory state in terms of quality. Therefore, the purpose is to solve the problems of the prior art.

Another object of the present invention is to be able to operate reliably, i.e. to obtain pleated fabrics of high quality accurately, even with soft fabrics, without the need for skilled workers and without critical adjustments. The object of the present invention is to provide a pleating machine that can be operated as follows.

Yet another object of the invention is to provide a pleating machine which is basically simple and relatively inexpensive, but which has pleating capabilities that can be applied to a variety of patterns.

These objects, and others which will become apparent from the following description, are intended to provide a working platform, said platform being adapted to impart intermittent forward motion to the fabric placed thereon. A fixed-angle swinging arm on the foot form, a contact wall that can be raised and lowered to bring the fabric into contact with the arm adjacent to the limit of movement, and a contact wall that has the function of guiding the pleated fabric and is connected to the arm. A pleating machine for creating sunflower-like converging folds in a fabric, the pleating machine having a guide member positioned adjacent to said wall on the opposite side, said contact wall as well as said arm interdigitating. said contact wall has a comb-like shape, and after the contact wall has been moved above the folded flap by said arm, said contact wall is pressed against said guide member to form a pleated fabric. This is achieved by means of a pleating machine which is provided with a control and guidance device for periodically oscillating movement of the wall along a path leading to the insertion position within said arm.

Other features and advantages of the invention will be readily understood from the description of preferred embodiments of the invention, which are not limited thereto, and taken in conjunction with the accompanying drawings, in which: FIG.

Means for Solving the Problem In the figures, the pleating machine of the present invention is generally designated by 1. The machine is for making pleated fabrics having sunflower convergent folds of the type shown in FIG. Pivotally mounted transport arm 4, said arm 4
, and a guide member 7 for the pleated fabric 2 .

Platform 3 is particularly shown in FIGS. The fabric is circular in shape and has been preformed but not yet pleated8
It extends around a pin 5 which is suitable for placing the arm 4 and forms the pivot center of the arm 4. Furthermore, the platform 3 is adapted to have its own oscillation in synchronism with the arm 4 about the same pin.

More specifically, the platform 3 has a main cylinder 9 which has the function of reciprocating the arm 4.
The arm 4 rotates intermittently in synchronization with the forward motion of the arm 4 driven by the arm 4 (FIG. 1). During the return movement of arm 4, platform 3 remains stationary.

Preferably, the main cylinder 9 itself controls both the reciprocating movement of the arm 4 and the forward movement of the platform 3. That is, as shown in FIG.
is connected to the pin 5 by a plate 10 connected to the center 11 of the pin 5, which pin 5 is connected to the platform 3 via a free gear mechanism 12 which can rotate in only one direction. . The free gear mechanism 12 is fixed to the platform 3 by a cup-shaped extension 13, also shown in FIG. Furthermore, the pin 5 is connected to the various elements connected to the pivot pin, in particular the fixed storage deck 14 lying on the platform 3 and the pivot pin 5 as well as the foundation 15 which provides a means of support for the entire machine, as will be explained below. It should be noted that it includes a pair of mating bearings.

The foundation 15 is particularly featured in FIGS. 4 and 5 and includes a grid for installation directly on the floor.

As shown, it is not only the foundation 15 that supports the pin 5, but also a pair of side plates extending substantially vertically and carrying substantially all parts of the machine 1. I support it. More specifically, as shown in FIGS. 4 and 5, the outer side plate 1 engages the main cylinder 9 and one end of the arm 4.
6 and an inner side plate 17 extending beyond the platform 3 from the pin 5 parallel to said side plate 16 and connected to the foundation beam 15a by a major section member 17a.
and is provided. The side plates 16, 17 also carry the control and guide device 49 of the wall 6. On the other hand, the control means for the arm 4 is provided only on the outer side plate 16. This is because arm 4 has inner side plate 17.
This is because it is simply connected to the pin 5 by the pin 5.

As shown in FIG. 6, the control means for the arm 4, in addition to the main cylinder 9, are constituted by a sliding groove 18 and are controlled by a pivot pin 19 projecting from the second end plate 20 of the arm. 4 can slide within the groove. The sliding groove 18 extends substantially parallel to the platform 3 and is lifted perpendicularly therefrom by an auxiliary cylinder 21 supported on the outer side plate 16. The stroke length of the sliding groove 18 is limited by an adjustable mechanical travel limit stopper 22 and a micro switch 23. For vertical movement of the arm 4, the main cylinder 9 has at least one pivotably connected end 9a (FIG. 1).

The aforementioned control guide device 49 for the wall 6 is configured to act on the upper crosspiece 24 of the wall 6 and comprises a lifting cylinder 25. The cylinder 25 is suspended from an upper pivot mount 26 and is supported by a lower pivot mount 27 with its working rod directly engaging the crosspiece 24. The device 4
9 further comprises a transverse cylinder 28 acting on a vertical tube 29 fixed to the crosspiece 24, perpendicular to the lifting cylinder 25. Finally, guiding means 30 are provided which define the path of the periodic movement of the crosspiece 24. The crosspiece 24 engages the guide means 30 by means of a projection 31 . All movements of the lifting cylinders 25 and the lateral cylinders 28 on each side plate 16, 17 are controlled by microswitches 32.

Figures 1, 2 and 6 show the structure of the arm 4 and wall 6.

The arm 4 is defined between its ends by an angle crosspiece 33 which extends perpendicularly to the angle crosspiece 33 and supports in a particular manner equidistantly spaced segments 34. It should be noted that Further, the spacing between each segment 34 is made substantially equal to the thickness of each segment 34 in a direction parallel to the angle crosspiece 33, that is, in the longitudinal direction of the arm 4.
The segment 34 overlaps a lower blade 35 which is also attached to the angled crosspiece 33.

Blades 35 are preferably formed by a set of side-by-side, partially independent small blades as shown in FIG. The blade 35 is located at a slight distance from the segment 34;
Preferably, it is pivotable relative to the latter. Overall, the front part of the arm 4 has a comb-like shape extending in the height direction to match the length of the pleat in which the segment 34 is to be formed.

The contact wall 6 also has a comb shape. That is, the wall 6 is constituted by the aforementioned cross piece 24 and a set of rods 36 attached to the cross piece 24. Preferably, the rod 36 extends primarily in a substantially vertical direction and resiliently engages the crosspiece 24. As shown in Figure 6,
Each rod 36 is connected at its top to a compression spring 37 inside crosspiece 24. The position of the spring 37 is adjustable by means of a screw 38. Each rod 36 is retained by a pin 39 passing through crosspiece 24 and a vertical slot formed in the rod itself.

As shown in FIGS. 2 and 6, the rod 3
6 is quite thin and parallel to the crosspiece 24,
It extends over a distance less than but comparable to the distance to segment 34. Furthermore, the rod 36 is such that the crosspiece 24 is always connected to segment 3.
It extends in the height direction so as to be held above 4. In this way the rod 36 can be inserted between the segments 34 of the arm 4.

The original or lower position of the crosspiece 24 is the position of the rod 3 when the arm 4 is in its most advanced position.
6 is chosen to be at the front end of segment 34. Furthermore, in this original position, the rod 36 and the plate 35 of the arm rest on the storage deck 14 mentioned above. The deck 14 is close to the rotating platform 3 and is connected to it by a ramp 40. The storage deck 14 is stationary, and the side plates 16,
The region between 17 and 17 is crosslinked.

As shown in FIG. 6, storage deck 14 includes a channel 41 adjacent wall 6 connected to an air jet supply member. The supply member is not shown in the figures as it is known. Additionally, the storage deck 14 includes an internal resistance heater in its midsection for processing prepleated fabric.
The guide member 7 comprises a cover 42, the structure of which is shown in FIG. The cover 42 includes an upper plate 43 which is supported by an elevating member 47 on the outer side plate 16 and whose other end is pivoted by a hinge 44 provided on the large section member 17a of the inner side plate 17.
It is substantially composed of.

As shown in FIG.
6 to the hinge 44. The central portion of the top plate 43, like the intermediate portion of the storage deck 14, has an electrical resistor mounted therein.

FIG. 2 shows how the upper plate 43 abuts the contact wall below the crosspiece 24, which is provided with a notch 24 designed to be inserted between the rods 36 of the contact wall 6. Segment 34 of arm 4 is only close to upper plate 43, but segment 34 is partially located where the teeth of plate 43 extend beyond rod 36.
It is also possible to insert it below the plate 43.

Figures 14 to 18 show a second embodiment of the machine 1, in which the guide member 4 is shaped to constitute a device suitable for heat treating and guiding a folded fabric 2. There is. Both the storage rod 14 and the upper plate 43 are heated directly and selectively.
It is divided into transverse sections connected to cooling elements.

As shown in FIG. 14, first transverse sections 11
3a and 113b are provided, which are enclosed points which cooperate to maintain the folded flap in a compact position. These first sections are followed by second transverse sections 114a, 114b forming suitable plate heaters that reach very high temperatures. The second transverse portions 114a, 114b include electrical resistance heaters as shown schematically in FIG. Second transverse portions 114a, 114b
The heat generated by the first transverse portion 113a, 1
13b as well.

Following the second transverse section are storage decks 1, respectively.
4 and the third transverse section 11 relative to the upper plate 43
5a and 115b are provided. These parts are formed by thin sheets interposed with a heat insulating material.

Finally, there is a fourth transverse section 116a, 116b with a unique construction as best shown in FIGS. 14, 15 and 17. These transverse sections preferably include a pair of fans that supply cool or room temperature air across the pleated fabric in a direction substantially perpendicular to the top plate 43 and substantially parallel to the flaps of the pleated fabric. It is immediately connected to a cooling member with 117.

Cooling air is supplied to the upper plate 43 and the storage deck 14.
is guided to flow along a straight path through both of the pleats without deviation or deviation in the direction perpendicular to the formed pleats. For this purpose, one side (outer side) of the fourth transverse section 116b
A hood 118 having the function of restricting the air flow generated by the fan 117 is provided on the side, and a first grid 119 tailored to fit the hood 118 is provided on the other side (inner surface). There is. Of course, the fourth transverse section 116b is formed by a hollow structure between the first grid 119 and the hood 118.

Air flow from.

Of course, the first grid 119 and the second grid 1
20 is arranged so as not to impair the continuity of the surfaces of the storage deck 14 and the upper plate 43.

The pleated fabric responds to the impact from the comb-like arms 4 which, by oscillating periodically, continuously press newly formed flaps onto the storage deck 14 in cooperation with the contact wall 6. and travels between the storage deck 14 and the upper plate 43 at a proportional speed necessary for heat treatment.

In order to carry out the appropriate heat treatment at the beginning and end of the processing step and at the moment each part of the fabric is processed,
In the present invention, the storage deck 14 and the top plate 43 are engaged with auxiliary elements that control the movement of the fabric. These auxiliary elements are shown in FIGS. 17 and 18.

As shown in FIG. 17, two racks 121 are installed on both sides of the storage deck 14 and together with a cross rod 122 and a motor unit 123 form a conveying device 134. The device 134 (when all the fabrics 2 have been conveyed past the contact wall 6)
Insertion of cross rod 122 and motor unit 12
It is activated by starting 3. The cross slot 122 is inserted between the arm 4 and the contact wall 6 after the contact wall 6 has been raised.

Specifically, rack 121 extends across and is axially driven by a gear 125 mounted on a control rod 126 located downstream of top plate 43.

The control rod 126 is rotated by a motor unit 123 including a pair of pulleys 127, a belt 128 and a motor 129. Motor 123
is located lower than the storage deck 14 on the side of the machine.

The cross rod 122, which is shaped to fit the formed folding flap and is replaceable, is attached to the rack 12.
1. The front ends of the two are engaged in a snap-like manner. For this purpose, the cross rod 122 contacts at one end a projection 130 projecting from the front end of one of the racks 121, and at the other end a compression spring 130.
The other rack 121 is engaged by a manually operated movable blade 131 against the biasing force of the second rack.

The speed provided by motor 129 is functionally related to the heat treatment applied to the fabric and is therefore slower if the heat treatment is more intense.

Finally, the stopping position of the conveyor 134 is determined by a pair of microswitches mounted on the side members 124 and adapted to sense the position of small pegs projecting from the ends of the racks 121.

In cooperation with, but independently of, the conveying device 134 described above, a slide 135 is provided for restraining the pleated fabric to the opposite side of the crossrod 122. The conveying device 134 is actuated at the end of each working step, and the slide 135 is actuated at the start of each working step, so that the flaps are folded up to a number that does not require any supporting action. To maintain a compact folded state of the flap by providing resistance to prevent the flap from slipping. The slide 135 can have a variety of shapes and dimensions, and includes a front element 136 and rack 12 shaped to match the flap being formed.
1 comprises a guide track 137 which is substantially slidable along one side. The running path 137 can have various lengths, and the slide 13 can have various lengths as required.
It can also be equipped with wheels and bearings to prevent tripping.

14 to 16, the degree of mutual compression of the pleats is increased, and the compression member 139 is attached to the upper plate 43.
2 shows how to increase the resistance to the forward movement of a pleated fabric by providing an additional auxiliary element for fabric movement control in the form of a . More specifically, the plurality of blades 140
are provided in conjunction with supporting members each designed to form an arcuate shape. The blade 14
0 is arranged in parallel with the lower piece of the fourth transverse portion 116b of the upper plate 43. The blade 1
40 straddles the first grid 119 and preferably includes a notch 141 so as not to impede airflow. For example, the support member is provided with a member 142 serving to lock one end of the blade 140 and a tension spring 14 on the opposite side of the member 142.
a bridging element 143 that engages each blade 140 by means of a spring 1;
The tensile force of 44 is adjustable by means of a screw element 145.

FIG. 14 also shows a peephole 148 or aperture devised to permit direct observation of the just-formed pleat, which aperture 148 is located in the contact wall 6.
It is provided on the upper plate 43 near the.

The aperture 148 includes a distinct fabric-limiting element. Finally, Figure 17 shows platform 3.
The jaws 150 are shown for controlling the movement of the. In particular, a first pair of electromagnetic traction jaws 150 mounted on and moving with the arm 4 and a second pair of stationary electromagnetic retention jaws 150 are provided (FIG. 17).

The traction or pulling electromagnetic jaw is positioned to engage and rotate the platform, while the holding or braking electromagnetic jaw is held open, and the latter is likewise brought into the open position by the traction electromagnetic jaw. done to. The jaw 150 cooperates with the free wheel mechanism 12,
It may also be replaced with this.

The operation of the pleating machine will be explained based on FIGS. 1 to 13.

First, the machine is in the position shown in FIG. 8 with the arm 4 positioned at its rearmost displacement limit from the wall 6.
The part 8 of fabric to be pleated is placed on the platform 3. The contact wall 6 is in its lower position and serves as a stop for the raw part of the fabric. The raw portion is lifted from the platform 3 and stacked on the storage deck 14 through the ramp 40. Any pleated fabric emerging beyond the wall 6 is retained there by the top plate 43 of the cover 42. The upper plate 43 enters the space between the rods 36 of the wall 6 from the front, and the lifting member 4
7 formed by the upwardly sprung position (fourth
Figure).

In order to form pleats or folded flaps in the fabric, the main cylinder 9 (FIG. 1) moves the arm 4 in arcuate directions closer to the wall 6. During this movement, the arm 4 rotates around the pin 5 connected to it via the plate 10, and the opposite side runs along the running groove 18 via the pin 19. During this working step, the running groove 18 is held downward by the auxiliary cylinder 21, and the arm 4 engages its blade 35 with the fabric part 8. The blade 35 is preferably held apart from the segment 34, so that any inaccuracies are absorbed by the deflection of the blade 35, so that the lower position of the arm 4 can be determined without special problems of operating tolerances. Can be done. Moreover, in that way the blade 35 itself can accommodate fabrics of various thicknesses and even overcome irregularities in the fabric's surface. In such a case, the second
It is particularly advantageous to divide blade 35 into a plurality of parallel blades as shown.

While the arm 4 is approaching the wall 6, an air jet is fed through the channel 41, which helps form the pleats even when using very soft fabrics (FIG. 9).

At the same time, the platform 3 is rotated together with the arm 4 by means of a conveying action exerted by the arm 4 via a free wheel mechanism 12 attached to the pin 5. In this way, the fabric stored on the platform 3 is not subjected to any tensile action and can therefore maintain its position without wrinkling, even if it is particularly soft.

As shown in particular in FIGS. 2, 6 and 10, the arms 4 form flaps of fabric with segments 34 aligned with the gaps between the rods 36;
It is positioned at its displacement limit so as to press against it.

While the new flap is formed and (preferably) held in place by specially provided channels 41 and segments 34,
The wall 6 has a lifting cylinder 25 and a lateral displacement cylinder 2
It is raised and displaced by the periodic oscillation caused by the action of 8. The path of movement of the wall 6 is defined by the running groove 18, and the rod 36 moves above the just formed flap and enters in a unique way the space between the segments 34 behind the flap itself.

This rocking movement is shown in FIGS. 11 and 12 and is achieved only by the comb-shaped configuration of the rods 36 and segments 34. This comb-like shape not only allows the rod 36 to be inserted between the segments 34, but also allows the rod itself to be raised without displacing the newly formed flap.

That is, the segment 34 does not in any case press the flap in question against the rod 36, but presents an overall very small contact surface to the flap.

At the end of the periodic oscillation, the rod 36 moves the just formed flap onto the guide member 7 of the pleated fabric 2.
The fabric is then subjected to a heat treatment carried out by a heating zone provided in the upper plate 43 of the storage deck 14.

In the final part of the cyclic rocking, the rod 36 moves against the blade 35 of the arm 4 and/or the storage deck 1.
It may interfere with the force due to 4. This is because, according to the invention, the rod 36 is attached by a spring and can easily absorb the periodic oscillations and the thickness of the pleated fabric applied thereto.

Finally, the arm 4 is moved rearward and raised by the action of the main cylinder 9 and the auxiliary cylinder 21. It acts to lift the running groove 18 on the auxiliary cylinder 21. During this movement, the platform 3 remains stationary. This is because the free wheel mechanism 12 is configured to transmit only the movement of the arm 4 toward the wall 6 to the platform 3 (FIG. 13).

In this way, the pleating machine 1 returns to its original position as shown in FIGS. 1 and 8.
The pleating is continued until all fabric sections 8 are completed, preferably in a continuous manner so as to pleat without interruption each fabric section 8 placed one after the other on the platform 3. This continuous processing is possible due to the rotational movement of the platform 3, whereby the fabric to be pleated is fed in succession and tensions and tensions thereof are avoided.

In the embodiment shown in FIGS. 14-18, sufficient heat treatment of the pleated fabric is also performed. The machine of the invention first applies heat to the fabric and then cools it. Cooling is very effective, as practical tests have shown that mere heating is not sufficient; upon exiting the machine, the "upright" pleats open and the fabric becomes flat. Since the fabric is still hot, this partial pleat collapse creates a permanent defect. It is therefore necessary to complete the entire heat treatment cycle by not only heating but also cooling before the pleat leaves the machine that formed it.

Effects of the Invention The apparatus of the present invention provides extremely excellent results in terms of quality. The pleats obtained are permanently stable. When the machine processes individual fabric sections or multiple garment products, the machine stops while the majority of the pleated fabric is still moving through the aforementioned heat treatment equipment. Do not remove the fabric by hand under any circumstances. This is because it causes pleat collapse and incomplete control of the length of time the fabric remains in the heat treatment area.

This situation must be carefully considered when adjusting the heat treatment equipment and feeding individual fabric products into it for testing purposes.

Adjustment of device operating parameters via transfer device 134 and slide 135 is also useful when processing very short sections of fabric. Since the running of the fabric is adjusted as desired by the pegs 146 acting on the blade 140, the handling of hemmed fabrics also presents no problems.

The edges of pleated fabrics include hem stitches, which tend to fan out the pleated fabric due to its thickness. Therefore, it is necessary to apply a stronger frictional force to prevent the mutual compression of the flaps from decreasing.

The disclosed invention is capable of many variations without departing from the scope of the inventive idea. Furthermore, the details of each part can also be replaced with other technically equivalent elements.

In carrying out the present invention, the materials and dimensions used can be appropriately selected according to each need.
