Description

Fabric pleating machine {Folding machine for fabric}

The present invention relates to a fabric pleating machine, and more particularly, to form irregular pleats in various directions that are not uniform on a fabric to save the aesthetics of the pleated fabric and greatly expand the range of use, while providing the fabric in the process of supplying the fabric. The present invention relates to a fabric pleating machine that maintains a constant supply direction of fabric to prevent reverse flow of the fabric or inability to smoothly supply the fabric, thereby guaranteeing productivity and manufacturing higher quality fabric pleats.

In general, when producing lace, clothing, curtains, duvet covers, bed covers, etc., wrinkles of a certain shape or irregularly wrinkled wrinkles are given by folding the fabric to make a line or inserting a blade vertically.

Conventionally, in order to form wrinkles on the fabric, a method of pushing the fabric into a bag having a certain shape and fixing the wrinkles with high-temperature steam or hot water has been manually performed, but the wrinkles are not formed evenly on the fabric, and the shape of the wrinkles It is simple, wrinkles are easily straightened, and mass production by manual work is impossible, so the unit price of the product rises.

Accordingly, recently, a mold method in which a heating device is provided inside and the fabric is heated when the fabric passes between the rotating forming rollers causes wrinkle patterns to be repeatedly formed by the irregularities of the forming roller, and the surface of the fabric passing through the guide roller. A pleating device such as a knife method in which a knife operates reciprocally to fold the fabric to form wrinkles is used.

At this time, in the case of the knife-type wrinkle forming device, in order to adjust the density or depth of wrinkles in the fabric, the operation of the knife and the feeding speed of the fabric must be appropriately controlled. , Basically, the operating speed of the knife must be operated as fast as that, and the input speed of the fabric must be properly controlled to match this.

However, in the process of feeding the fabric toward the knife, if the fabric is rolled by the roller that moves the fabric due to static electricity or the viscosity of the surrounding rollers, a phenomenon in which the fabric flows backward occurs, making it impossible to smoothly supply the fabric. It was difficult to guarantee the quality of pleats because productivity was lowered and the supply of fabric was irregular.

Opposite to this, the upper roller 30 is rotatably installed on top of the lower roller 20, and both left and right ends are mounted on the long grooves 12 of the support 11, so that the supplied fabric (P) In contact with the upper surface of the fabric (P) is pulled to the rear where the wrinkle forming portion (2) is located.

That is, the fabric P supplied from the side of the fabric supply roll 13 may pass between the lower roller 20 and the upper roller 30 and be continuously supplied to the wrinkle forming unit 2 .

The lower roller 20 does not rotate by a separate power means, and only the upper roller 30 mounted on the long groove 12 of the support 11 is connected to a drive motor 40 to be described later to receive power and rotate. can do. At this time, the lower roller 20 may pull the fabric P by rotating in the reverse direction in conjunction with the rotation of the upper roller 30 in a state in contact with the outer circumferential surface of the upper roller 30.

A lower circumferential groove 21 and an upper circumferential groove 31 may be recessed on outer circumferential surfaces of the lower roller 20 and the upper roller 30 in the circumferential direction, respectively.

Each of the lower circumferential groove 21 and the upper circumferential groove 31 may be formed in plural at equal intervals along the axial direction (left and right), and a main part of the backflow prevention member 80 to be described later may pass therethrough. there is.

Next, the support bracket 50 may be coupled to at least one of the pair of support frames 10 to support the drive motor 40 .

The support bracket 50 is formed in a 'c' shape in which the front, upper and lower sides are simultaneously opened, supports the drive motor 40 to the outside, and can accommodate the drive shaft of the drive motor 40 to the inside. . At this time, the first sprocket 41 may be coupled to the driving shaft of the driving motor 40 .

Next, the connecting chain 60 is installed between the drive shaft of the drive motor 40 provided inside the support bracket 50 and the end of the upper roller 30 to transfer power of the drive motor 40 to the upper roller 30. ) is forwarded to

At this time, the second sprocket 32 may be coupled to the end of the upper roller 30, and the connecting chain 60 connects the first sprocket 41 and the second sprocket 32 to each other. can make it

On the other hand, in the case of the upper roller 30, it is configured to be able to adjust the position in the vertical direction within the formation range of the long groove 12 of the support 11. At this time, the upper roller 30 and the drive motor 40 are connected to the chain 60 Since they are connected to each other by ), even if the position of the upper roller 30 is adjusted in the up and down direction in the direction of the arrow shown in FIG. 8, the power of the driving motor 40 can be provided to the upper roller 30 without interruption. .

As a configuration for adjusting the position of the upper roller 30 in the up and down direction, as shown in FIG. 8, a bearing 33 is coupled to one end of the upper roller 30 and an adjustment handle 34 to the top of the bearing 33 ) is coupled and has a structure coupled to the second screw hole 14 formed on the upper surface of the support 11 in a screwing manner.

The bearing 33 may be in contact with the inner wall surface of the groove 12 and rotatably supports the upper roller 30 therein.

The control handle 34 may be coupled so as to rotate on the coupling table 35 protruding upward from the bearing 33, and extends upward to be exposed to the outside of the support base 11.

A screw thread is formed on the outer circumferential surface of the control handle 34 and can be coupled to the second screw hole 14 in a screwing manner. Accordingly, when the user rotates the control handle 34, the support 11 moves up and down. The upper roller 30 is towed to the control handle 34 whose position is controlled by , so that the height of the upper roller 30 can be adjusted.

Thus, the vertical height of the upper roller 30 can be flexibly adjusted in consideration of the thickness of the fabric P on which wrinkles are to be formed.

On the other hand, when tolerances such as straightness and cylindricity of at least one of the upper roller 30 and the lower roller 20 are large, the upper roller 30 and the lower roller 20 are not in contact with each other in a specific section. phenomenon occurs. In this case, the fabric P cannot be smoothly supplied, and if the fabric P is folded between the upper roller 30 and the lower roller 20, there is a problem in that inaccurate and irregular wrinkles are formed.

Accordingly, the supply unit 1 has a structure in which the upper roller 30 and the lower roller 20 can be more airtightly contacted without being separated by a tolerance by pressing a specific section of the upper roller 30 .

To this end, a pressing bar 15 may be formed in the support frame 10 to connect the upper portions of the respective supports 11 and through which a plurality of first screw holes 16 are formed at regular intervals in the vertical direction.

In addition, the supply unit 1 may further include a pressing member 70 that is coupled to a corresponding location of each of the plurality of first screw holes 16 and presses the upper roller 30 from the top.

That is, the upper roller 30 and the lower roller 20 may be brought into close contact with each other by pressing a specific section of the upper roller 30 from the top using each pressing member 70 .

The pressure bar 15 is provided at the uppermost height of the support 11 and may be spaced apart from the top of the upper roller 30 by a predetermined distance.

Each of the plurality of pressing members 70 may be spaced apart at equal intervals and hung on the pressing bar 15 .

Each of the plurality of pressing members 70 includes a pressing handle 71 coupled to the first screw hole 16 in a screwing manner, a roller carrier 72 coupled to the lower end of the pressing handle 71, and the roller It may be exemplified as including a pressure roller 73 coupled to the carrier 72 so as to be rotatable in place and contacting the outer circumferential surface of the upper roller 30 in a rolling manner.

The pressure handle 71 may be coupled to the roller carrier 72 to idle, and is formed extending upward to be exposed to the top of the pressure bar 15.

A screw thread is formed on the outer circumferential surface of the pressure handle 71 and can be coupled to the first screw hole 16 in a screwing manner.

The roller carrier 72 is formed in a 'ㅗ' shape and can support at least one pair of pressure rollers 73 rotatably in place at both front and rear ends.

Accordingly, when the upper roller 30 and the lower roller 20 are spaced apart from each other in a specific part, the user can manipulate the pressing member 70 at the position where the spaced part is located. That is, when the user rotates the pressing handle 71 of the specific pressing member 70, the roller carrier 72 is pulled to the pressing handle 71, which is positioned vertically on the pressing bar 15, and is positioned in the vertical direction. Therefore, the pressure roller 73 is in contact with at least two points in the front-back direction of the upper outer circumferential surface of the upper roller 30, and in some cases, the pressure applied to the upper roller 30 is adjusted so that the upper It is possible to configure the roller 30 closer to the lower roller 20.

Next, the backflow prevention member 80 is installed in front of the pair of support frames 10, and the fabric P passing between the upper roller 30 and the lower roller 20 is connected to the upper roller 30 and the lower roller 30. It is wound around at least one of the rollers 20 and serves to prevent reverse flow in the reverse direction of the supply direction.

That is, the backflow prevention member 80 is the upper roller 30 and the lower roller 20 in the course of pulling the fabric (P) toward the wrinkle forming unit 2 between the upper roller 30 and the lower roller 20 By preventing the fabric (P) from being arbitrarily wound on and at the same time supplying the fabric (P) in a flat unfolded state, problems caused by the fabric (P) reverse flow, for example, supply disruption of the fabric (P), deterioration in wrinkle quality, etc. It can be prevented.

More specifically, the backflow prevention member 80 largely includes a holder 81, a first support bar 82, a first backflow prevention pin 83, a guide plate 84, and a second backflow prevention pin 85 And it may be illustrated as including a taping member (86).

First, the cradle 81 may be provided as a pair so as to be respectively installed on the upper part of the front of the pair of support frames 10, and may be integrally configured with the support frame 10.

Next, the first support bar 82 crosses between the pair of support frames 10 and is coupled to the pair of holders 81 .

That is, both ends of the left and right sides of the first support bar 82 may be mounted on the cradle 81 spaced apart from each other, and may be spaced upward from the support frame 10 by the height of the cradle 81 .

The first support bar 82 plays a role of fixing and supporting one end of the first backflow prevention pin 83 .

Next, the first backflow prevention pin 83 extends from the first support bar 82 toward the upper circumferential groove 31 of the upper roller 30 and passes through the upper roller 30 in the front and rear directions. .

At this time, one end of the first backflow prevention pin 83 may be fixed to the first support bar 82 and the other end may be formed in the form of a free end at a point passing through the upper roller 30 .

A plurality of first backflow prevention pins 83 may be arranged at equal intervals along the longitudinal direction of the first support bar 82 so as to pass through the plurality of upper circumferential grooves 31 , respectively.

The other end of the first backflow prevention pin 83 extends to the boundary between the supply unit 1 and the wrinkle forming unit 2, so that the upper surface of the fabric P passing through the upper roller 30 and the lower roller 20 can be guided in a straight line.

Next, the guide plate 84 may be coupled between the pair of support frames 10 at a lower position of the first support bar 82 .

The guide plate 84 plays a role of fixing and supporting one end of the second backflow prevention pin 85 and at the same time prevents the fabric P supplied from the fabric supply roll 13 from forming any wrinkles. It plays the role of guiding by spreading it flat. A specific structure of the guide plate 84 for this will be described later.

Next, the second backflow prevention pin 85 crosses the upper part of the guide plate 84 in a state of being in contact with the upper surface of the guide plate 84 but extends toward the lower circumferential groove 21 to form a lower roller ( 20) is composed of a structure passing through.

At this time, one end of the second backflow prevention pin 85 is fixed to the guide plate 84 by the taping member 86 and the other end is formed as a free end at a point passing through the lower roller 20 .

A plurality of second backflow prevention pins 85 may be arranged at equal intervals along the longitudinal direction (left and right direction) of the guide plate 84 so as to pass through the plurality of lower circumferential grooves 21 , respectively.

The other end of the second anti-backflow pin 85 extends to lie on the same line as the other end of the above-described first anti-backflow pin 83, and the fabric P passing through the upper roller 30 and the lower roller 20 The bottom of the can be guided in a straight line.

At this time, a gap exists between the first anti-backflow pin 83 and the second anti-backflow pin 85, at least enough for the far end P to be interposed therebetween.

Accordingly, the fabric P passing between the upper roller 30 and the lower roller 20 is placed on the upper and lower portions to the other end points of the first anti-backflow pin 83 and the second anti-backflow pin 85, respectively. It is guided by the first anti-backflow pin 83 and the second anti-backflow pin 85 and can be supplied in a flatly developed state.

That is, the first backflow prevention pin 83 and the second backflow prevention pin 85 are in front of the upper roller 30 and the lower roller 20, the fabric P is the upper roller 30 and the lower roller 20 The fabric P is guided so that it is accurately supplied between the upper roller 30 and the lower roller 20, and the fabric P passing through the upper roller 30 and the lower roller 20 does not flow backward and is flat. Guides the fabric (P) so that it can be developed and discharged toward the wrinkle forming portion (2).

If the first backflow prevention pin 83 and the second backflow prevention pin 85 are excluded, the original fabric P towed between the upper roller 30 and the lower roller 20 may cause the upper roller ( 30) or reverse flow by being wound around the lower roller 20, or not supplied in a flatly developed state, resulting in unwanted irregular wrinkles being formed between the upper roller 30 and the lower roller 20, or disruption in the supply of the fabric may occur.

Meanwhile, the taping member 86 serves to adhere and fix the second backflow prevention pin 85 in contact with the upper surface of the guide plate 84 to the guide plate 84 .

That is, one end of the second backflow prevention pin 85 may be adhesively fixed on the guide plate 84 by the taping member 86, and a portion of the upper surface of the guide plate 84 is formed by the taping member 86. This can be covered.

More specifically, the guide plate 84 includes a horizontal plate 84a placed horizontally, a first vertical plate 84b bent and extended vertically downward from the front end of the horizontal plate 84a, and the horizontal plate 84a. It may be exemplified as including a second vertical plate 84c bent and extended vertically downward from the rear end of the.

The fabric (P) is supplied in a state of contact with the upper part of the horizontal plate (84a), and the fabric (P) before the fabric (P) is put into the upper roller 30 and the lower roller 20 is the horizontal plate ( 84a) can be supplied in a wide open state.

At this time, the taping member 86 is continuously attached only to the horizontal plate 84a and the first vertical plate 84b so that the second backflow prevention pin 85 is attached to the horizontal plate 84a and the first vertical plate 84b. It is adhesively fixed only to the surface of the plate, and accordingly, the second backflow prevention pin 85 is not exposed to the outside in the horizontal plate 84a and the first vertical plate 84b, and the taping member on the surface of the guide plate 84 (86) is equipped with a covered state.

The reason why the taping member 86 is attached to the first vertical plate 84b is because the fabric P is supplied in the direction in which the first vertical plate 84b faces, so the second backflow prevention member 80 is attached to the fabric P ) in order not to interfere with the supply of

In particular, since the taping member 86 is exemplified in the form of a synthetic resin adhesive film with a relatively lubricated surface, less static electricity is generated and no resistance is generated with the fabric (P), so the fabric (P) guide plate ( 84) is not congested and can pass smoothly.

That is, since the fabric P can be supplied between the upper roller 30 and the lower roller 20 in a flat unfolded state, the fabric P is folded between the upper roller 30 and the lower roller 20, or A phenomenon in which the supply of the fabric P is delayed can be more effectively prevented.

In addition, since the taping member 86 covers one end of the second anti-backflow pin 85 with a sufficient area and adheres to the outer surface of the guide plate 84, it is possible to sufficiently secure the fixing force of the second anti-backflow pin 85. can

Next, the wrinkle forming unit 2 is installed connected to the rear of the supply unit 1, and largely includes a support structure 100, a fabric guide roll 200, a leaf spring 300, a first knife member 400, a knife It may be illustrated as including a drive shaft 500 and a connecting rod 600.

The plate spring 300 is a fabric guided by the fabric guide roll 200 so that the fabric P guided by the fabric guide roll 200 can be guided without separation while in uniform contact with the outer circumferential surface of the fabric guide roll 200. It consists of a structure that wraps around the outside of (P).

One end and the other end of the leaf spring 300 are each fixed on the support structure 100, and at a point passing through the fabric guide roll 200, it is bent so as to be offset from the outer circumferential surface of the fabric guide roll 200 to the outside, so that the fabric It has a certain gap with the guide roll 200, and thus, the paper and laminated fabric P can pass through the gap between the fabric guide roll 200 and the leaf spring 300 while being interposed.

A plurality of leaf springs 300 may be continuously provided along the axial direction of the fabric guide roll 200, and may be removed or added on the support structure 100 depending on circumstances.

A plurality of forming holes 310 are cut in each leaf spring 300 along the longitudinal direction, and the laminated fabric P may be exposed through the forming holes 310 . Then, the first knife member 400, which will be described later, reciprocates toward the forming hole 310 to fold the fabric P inside the forming hole 310.

Next, the first knife member 400 serves to form wrinkles on the fabric P by operating toward the fabric P interposed between the fabric guide roll 200 and the leaf spring 300.

Configurations such as the first knife member 400, the knife drive shaft 500, and the connecting rod 600, which will be described later, operate in conjunction with the fabric P exposed through the forming hole 310 of the leaf spring 300 to fabric ( P) plays a role in wrinkles.

The knife driving shaft 500 may be connected to a knife driving motor (not shown) and rotate by receiving power from the knife driving motor. For example, a first knife driving gear may be integrally formed at an end of the knife driving shaft 500, a second knife driving gear is coupled to the driving shaft of the knife driving motor, and the first knife driving gear and the second knife driving gear can be connected through a connecting means such as a chain, and thus a structure capable of transmitting the power of the blade driving motor to the knife driving shaft 500 is provided.

The connecting rod 600 is eccentrically mounted on the outside of the knife drive shaft 500 to convert the rotary motion of the knife drive shaft 500 into a linear motion and is coupled to the first knife member 400.

One end of the connecting rod 600 is provided to be able to slip on the outside of the eccentric cam 700 provided outside the knife drive shaft 500, and the other end supports the first knife member 400.

Accordingly, as shown in FIG. 10, when the knife driving shaft 500 rotates in place by the knife driving motor, the eccentric cam 700 rotates accordingly, and the connecting rod 600 slips outside the eccentric cam 700. The rotational motion of the knife drive shaft 500 is converted into linear motion to reciprocate the first knife member 400 in a linear direction.
