Description

Cutting and adhering unit of roll fabric processing system {CUTTING ATTACHING UNIT FOR ROLL PROCESSING SYSTEM}

The present invention relates to a cutting and bonding unit of a roll fabric processing system, and more specifically, to a roll fabric processing system equipped with a knife member that has a structure to prevent bending when heated when the knife member that performs cutting and bonding of roll fabric is heated. It relates to a cutting and adhesive unit.

Generally, roll fabric is manufactured into products such as packaging plastic bags, disposable packaging bags, rolling bags, head polybags, etc. by using side sealing, back sealing, three-side sealing, M-room sealing, automatic band sealing, shrink film sealing, and OPP half-folding. And it is processed by methods such as full processing, head processing, and roll cutting.

As disclosed in Korean Patent Nos. 0313033 and 0351587, the conventional roll fabric processing system supplies film fabric wound on a fabric roller by changing the direction using a tripod or by folding the film fabric in half.

Referring to Figure 1, the cutting and adhesive unit 10, as described above, is reciprocated by the base roller 13 rotatably installed on the frame 12 and the support bar 15, and is attached to the base roller 13. It is provided with a knife member 14 that selectively contacts to cut and adhere the film fabric (not shown) located on the surface of the base roller 13.

The knife member 14 moves back and forth at high speed with respect to the base roller 13 in a state heated to 450°C to 600°C for cutting and adhesion of the roll fabric, and comes into contact with the base roller 13 to cut and adhere the roll fabric. do.

At this time, the knife member 14 expands due to heating, causing bending in various directions. Accordingly, there is a problem in that the cutting and adhesion of the roll fabric is formed unevenly.

In addition, since the knife member 14 contacts the base roller 13 at high speed, the central portion of the base roller 13 has a high tendency to bend downward due to such contact force. Therefore, when the cutting and adhering unit 10 is operated at high speed for a long time, the efficiency of the cutting and adhering work is reduced, such as a phenomenon in which the central part of the film fabric is not cut due to bending or sloshing in the longitudinal direction of the base roller 13. There is a problem with falling.

In addition, when cutting and adhering work is performed at high speed, the residue of the film fabric sticks to the base roller 13, making it difficult to stop the work and clean the surface of the base roller 13 to remove it. there was.

Here, the take-out motor 142 is a normal electric motor capable of servo control and with a built-in electronic clutch brake.

As shown in FIGS. 3 and 4, the cutting and adhesive unit 150 cuts the base roller 152 rotatably installed on the frame 102 and the film fabric 122 supplied onto the base roller 152. At the same time, it is provided with a support member 155b to prevent deformation of the knife member 154 and the base roller 152 that are thermally compressed.

The knife member 154 has a structure to prevent bending when it expands by heating.

Figure 5 is a front view of the knife member 154 provided in the cutting and adhesive unit of the roll fabric processing system, and Figure 6 is a side view of the knife member 154 of Figure 5.

As shown in FIGS. 5 and 6, the knife member 154 cuts the rectangular bar-shaped body portion 1541 and the film fabric 122 forming the body of the knife member 154 and simultaneously cuts the base roller 152. A blade portion 1543 formed on the bottom of the body portion 1541 to interact with and adhere the film fabric 122 folded in two by thermal compression, and an upper portion forming the back of the body portion 1541. A bending-prevention convex portion 1547 formed on the surface to prevent bending of the knife member 154, and a heating wire 1548 and a heating wire (1548) inserted through the body portion 1541 and the blade portion 1543 along the longitudinal direction. A plurality of hot wire portions 1550 including hot wire terminals 1549 formed on both exposed ends of 1548 and the upper surface of the body portion 1541 to secure the knife member 154 to the knife block 153. It is comprised of three or more fixing parts 1553 spaced apart from each other at intervals.

The bending-prevention concave-convex portion 1547 is located in a direction perpendicular to the longitudinal direction of the body portion 1541 in the area between the fixing portions 1553 formed on the upper surface of the body portion 1541 forming the back of the knife member 154. It is composed of a plurality of recessed portions 1545 and convex portions 1547 formed by a plurality of slots.

At this time, when the ratio of the width of the concave portion 1545 (or the width of the convex portion 1547) to the depth of the concave portion 1545 (or the height of the convex portion 1547) is 1: 1.1 to 1.3, the heating portion 1550 ) was confirmed to be excellent in preventing warping due to thermal expansion when heated. That is, when the length of the knife member 154 is 800 mm, the width of the recessed portion 1545 (or the width of the convex portion 1547) is 10 mm, and the depth of the recessed portion 1545 (or the height of the convex portion 1547) is 12 mm. When formed, the least amount of bending of the knife member 154 due to thermal expansion occurred.

This means that the bending-prevention convex-convex portion 1547 functions as a heat dissipation fin to cool the upper surface of the knife member 154, and at the same time performs the function of a beam, so that the bending-prevention convex-convex portion 1547 of the body portion 1541 This is because thermal deformation in the adjacent area of the bending-prevention convex-convex portion 1547 of the body portion 1541 is minimized by cooling and fixing the adjacent area.

When the fixing parts 1553 are formed in three pieces, they are formed on both sides and the center of the upper surface of the body part 1541, and the fixing parts 1553 are formed on both sides and the center of the upper surface of the body part 1541. By connecting and fixing the knife block 153, bending deformation due to thermal expansion at both sides and the center of the knife member 154 is prevented.

Figure 7 is a front view showing the cutting and adhering unit of the roll fabric processing system equipped with the bending prevention cap portion 1560 according to another preferred embodiment of the present invention, and Figure 8 is provided in the cutting and adhering unit of the roll fabric processing system of Figure 7. FIG. 9 is a front view of the knife member 154 provided with the bending prevention cap portion 1560, and FIG. 9 is a side view of the knife member 154 of FIG. 8.

7 to 9, the cutting and adhering unit 150' of the roll fabric processing system of another embodiment of the present invention has a knife member 154 in addition to the configuration of the knife member 154 of FIGS. 4 to 6. It may be configured to further include a bending prevention cap portion 1560 that is coupled.

The bending-prevention cap portion 1560 includes a plurality of recessed portions 1565 and convex portions 1566 formed by a plurality of slots to engage with the recessed portions 1545 and convex portions 1546 of the bending-prevention convex portion 1547. It is composed of an anti-bending cap uneven portion (1567).

As shown in FIGS. 8 and 9, the bending-prevention cap portion 1560 of the above configuration is coupled to engage with the bending-prevention concave-convex portion 1567 of the knife member 154 and then fixed by a fixture such as a bolt or welded as one piece. By minimizing thermal deformation of the knife member 154, bending phenomenon is minimized when the film fabric 122 is heated for cutting and bonding.

To this end, the bending-prevention cap portion may be made of a material with a high heat distortion temperature, such as CCM (Carbon Ceramic) material that does not undergo heat distortion at 1300°C.

As described above, the bending-prevention cap portion 1560 is manufactured from a material with high thermal strain such as CCM, and then combined with the bending-prevention convex portion 1567 of the knife member 154, and then the knife member 154 is heated. In this case, the bending prevention cap portion 1560 supports the thermal deformation of the convex and convex portion 1567 to prevent bending of the knife member 154, making it possible to further minimize thermal deformation of the knife member 154 due to heating.

In addition, the cutting and adhesive unit 150' of the present invention has a bolt hole so that the bending deformation can be adjusted to the original shape by pressing the upper surface of the knife member 154 when the knife member 154 is bent in the downward or upward direction. A support 1571 is formed and fixed to the fixing rod 153a connecting the fixing part 1553 and the knife block 153 and is coupled to the bolt hole to press or pressurize the upper surface of the knife member 154 when necessary. It may be configured to further include a pressing portion 1570 consisting of a pressing bolt 1573 that releases to finely adjust the height of the blade portion 1543.

In the case of FIG. 7, the pressing part 1570 is shown as being configured to press the bending-prevention cap part 1560, but the pressing part 1570 is provided in the cutting and adhesive unit 150 of FIG. 4 and the knife member 154 It may be configured to pressurize the anti-bending convex portion 1547.

The pressurizing portion 1570 of the above configuration prevents bending with the pressurizing bolt 1573 coupled to the fixing rod 153a located in the center when cutting or adhesion defects occur in the central portion of the film fabric 122 to be cut and bonded. The concavo-convex portion 1547 or the bending-prevention cap portion 1560 is pressed, and the bending-prevention convex-convex portion 1547 or the bending-prevention cap portion 1560 of the pressure bolt 1573 coupled to the fixing rod 153a on both sides is pressed. By releasing it, the height of the center of the blade portion 1543 can be lowered to finely adjust the height of the center of the blade portion 1543 so that the blade portion 1547 and the base roller 152 are in close contact over the entire area.

In contrast, the pressing portion 1570 bends the pressing bolt 1573 coupled to the fixing rod 153a located in the center when cutting or adhesion defects occur on both sides of the film fabric 122 to be cut and bonded. The pressure of the anti-bending and protruding portion 1547 or the anti-bending cap portion 1560 is released, and the anti-bending and protruding portion 1547 or the anti-bending cap portion 1560 is secured with the pressurizing bolt 1573 coupled to the fixing rod 153a on both sides. By pressing, the height of the center of the blade portion 1543 is slightly raised and the height of both sides is lowered so that the blade portion 1547 and the base roller 152 are in close contact over the entire area. Allow it to be adjusted.

The knife member 154 is fixed to the knife block 153 by the fixing part 1553 and the fixing rod 153a, and is then positioned on the base roller 152 while reciprocating vertically with respect to the base roller 152. At the same time as cutting the film fabric 122, the film fabric 122 folded in two is adhered by heat compression.

The knife member 154 is made up of a motor 156 installed on the frame 102, a link unit 190 connected to an eccentric cam 158 rotated by the motor 156, and a link unit 190 of approximately A rotating part 192 installed on the frame 102 to rotate 10 mm, and a rotating part connected to the rotating part 192 to accelerate the rotating force of the rotating part 192 by about 5 times to reciprocate the knife member 154 by about 50 mm It reciprocates by the pressing part 194 and the buffering part 196 to cushion the rotational movement of the rotating part 192.

The pressurizing unit 194 is operated by hydraulic or pneumatic pressure and uses a conventional cylinder controlled by a control unit. In addition, when the system 100 is stopped, the pressurizing unit 194 raises the support bar 157 to space the knife member 154 and the base roller 152. Therefore, it is possible to prevent the base roller 152 and the take-out rollers 144 and 146 from being damaged by the high-temperature knife member 154.

The buffer unit 196 is used to relieve the shock applied to the knife member 154 and the base roller 152 by alleviating the impact force when the rotating unit 192 rotates, and a normal shock absorber is used.

The knife member 154 has a heating wire 154a installed therein and is controlled by a control unit to be heated to about 600°C. In addition, the knife member 154 is installed on the knife block 153 with its horizontal position adjusted by the position adjustment member 155. Both ends of the knife block 153 are rotatably supported by the knife frame 159, and the knife frame 159 is supported by the support bar 157. The support rod 157 is connected to the pressing portion 194 and moves.

The knife member 154 operates at a high temperature, and in particular, when working at high speed, the residue from the film fabric 122 easily sticks to the blade of the knife member 154, so the knife member 154 must be cleaned at regular time intervals. . Therefore, it is preferable that the knife member 154, together with the knife block 153, be installed so as to be rotatable by 90 degrees or 180 degrees with respect to the knife frame 159. For this purpose, a lever (153a) is installed on the knife block (153).

It is provided with a motor (161). Here, the conveyor drive motor 161 is a normal servo electric motor and is controlled by a control unit. Since the conveyor unit 160 is disclosed in Korean Patent Registration No. 0313033 and Korean Patent Registration No. 0351587, detailed description will be omitted here.

Next, the operation process of the cutting and adhering unit 150 of the roll fabric processing system according to the preferred embodiment of the present invention will be described. Since the cutting and adhering unit 150 is installed and operated in the roll fabric processing system 100, the operating process of the roll fabric processing system 100 will be described together.

First, turn on the power of the system 100 and input the necessary data into the control unit. The pull-out motor 142 rotates the pull-out rollers 144 and 146 to pull out the film fabric 122 stored in the storage unit 130 to suit the length of the product according to the control value of the control unit. At the same time, the supply motor 127a drives the supply rollers 123 and 125 to supply the film fabric 122 to the storage unit 130. In this process, the direction of the film fabric 122 is changed by the tripod 128 and folded into two layers, and is pressed by the pressing rollers 127 and 129. In addition, the adhesive liquid is applied to the film fabric 122 by the adhesive liquid application means 121 and then dried.

The process of withdrawing the film fabric 122 stored in the storage unit 130 is disclosed in Korean Patent Registration No. 0313033 and Korean Patent Registration No. 0351587, so description will be omitted here.

When the film fabric 122 flows into the base roller 152, the control unit operates the motor 156 to lower the support rod 157.

Then, the raised knife member 154 is lowered to cut and bond a predetermined portion of the film fabric 122. At the same time, the support portion 155c of the support member 155b rises to support the base roller 152. In addition, the cleaner 155h provided on the support portion 155c removes residues from the film fabric 122 stuck to the base roller 152.

That is, the motor 156 rotates the eccentric cam 158, and the link unit 190 moves back and forth a predetermined distance by the rotation of the eccentric cam 158. Then, the rotating part 192 is rotated a predetermined distance by the link part 190, and the pressing part 194 increases the rotating force of the rotating part 192 to raise and lower the support bar 157. The knife frame 159 is raised and lowered by the elevation of the support bar 157, and the knife block 153 and the knife member 154 installed in conjunction with it reciprocate at a predetermined period. In this process, the take-out rollers 144 and 146 move the film fabric 122 again at a predetermined distance.

In addition, the support portion 155c of the support member 155b receives driving force from the motor 156 and supports the base roller 152 while reciprocating at the same cycle as the knife member 154. That is, at the same time that the knife member 154 contacts the base roller 152, the support portion 155c supports the base roller 152 to prevent deformation of the base roller 152.

The product 162 cut and bonded through this process is discharged through a pair of conveyors 168 and 169 driven by the conveyor motor 161 and stored in the discharge tray 166.
