The present invention relates to a rollback sealing and tear line forming device.

In general, the rollback is made by continuously winding the plastic bag so that it can be cut into the branch pipe.

This rollback is produced by sealing the vinyl fabric continuously fed in a tube shape at regular intervals, forming a cut line in the sealed one side direction, and then winding the paper tube.

At this time, the sealing is to seal one end of the plastic bag, the perforation line is to be used to tear off the plastic bag one by one.

As shown in FIG. 1, the rollback sealing and tearing line forming apparatus 1 is wound up while pulling and transporting the vinyl fabric from the supply part 2 and the supply part 2 for continuously supplying the vinyl fabric V. FIG. It is installed between the transfer windings 3, and is combined in this way, to constitute one rollback manufacturing apparatus.

However, since the sealing roll 1a and the cutting line 1b are separately installed apart from each other in the conventional rollback sealing and tearing line forming apparatus 1, the apparatus must be enlarged and occupy a limited work space. There is a problem.

In addition, since the sealing means (1a) and the cutting means (1b) are installed separately from each other, there is a problem that an error occurs in the gap between the sealing shoe and the cutting line forming part due to the transfer state of the vinyl fabric or by the error generated in the interlocking process. There is this.

In addition, since the sealing line and the cut line forming portion should be changed according to the length (size) of the plastic bag, there is a problem that the setting operation by adjusting it is required, and thus, there is a problem that the manufacturing process must be stopped.

In addition, since the elevating drive unit for the lifting operation of the sealing means (1a) and the elevating drive unit for forming the cut line must be provided separately, there are many problems in the component.

Particularly, in the technical contents of the prior art domestic registered utility model publication No. 20-0367824 and Japanese Utility Model Utility Publication No. 53-005567, there is a need to separately provide a lift driver for forming a cut line, and the sealing line and the cut line forming part are adjusted. Problems such as setting work to be separately required are pointed out.

The present invention comprises a sealing means for forming a sealing line by heat-sealing the vinyl fabric continuously supplied by the winding unit in the lifting operation by the drive unit in the upper and lower surfaces; In the rollback sealing and tearing line forming apparatus including a cutting means for forming a cutting line on one side adjacent to the sealing line while the elevating operation by the drive unit, the sealing means and the cutting means are provided integrally, at the same time the sealing line and the cutting line with respect to the vinyl fabric Forming sealing / cutting section 1; A sealing / cutting part 2 having the same configuration provided at intervals on one side of the sealing / cutting part 1; An upper part is fixed to both sides of a lifting part of the sealing means, and a lower part is provided on both sides of the fixing part of the sealing means, and holding parts for holding both ends of the vinyl fabric according to the lifting of the sealing means; A sealing / cutting interval adjusting part which is provided to be elevated in the middle portion of the sealing / cutting part 1 and the sealing / cutting part 2 and adjusts the length of the vinyl fabric through the seal; It characterized in that it comprises a; control unit for controlling the conveying length of the vinyl fabric of the winding.

According to the present invention, since the sealing means and the cutting means are installed adjacent to each other independently of each other, the device can be extremely miniaturized.

In addition, the present invention, since the sealing means and the cutting means are installed adjacent to each other without being separately installed apart, even though the sealing water unit and the cut line forming portion is changed according to the length of the plastic bag, the sealing water unit and the cutting line forming portion without the separate setting work The spacing can always be made constant.

Further, according to the present invention, since the cutting line is naturally formed by the lifting operation of the sealing means, it is not necessary to separately provide the lifting driving unit for the sealing line and the lifting driving unit for the cutting line to reduce the component.

In addition, the present invention provides a plurality of seals / cuts, by adjusting the length of the vinyl fabric located between each seal / cuts by adjusting the sealing and cutting interval, a plurality of seals and cut lines in the lifting operation of one cycle In this way, the productivity can be improved, and the gap between the sealing and the cutting line can be adjusted without moving the position of the sealing / cutting part itself, thereby improving the operability according to use.

The present invention will be described below with reference to the accompanying drawings presented as above.

First, the present invention, as shown in the accompanying drawings, Figure 3, sealing means 11 for sealing by heat-sealing while lifting the vinyl fabric (V) continuously supplied by the winding unit 20 by the drive unit 12 ; The rollback sealing and cutting line forming device 10, which includes a cutting line 13 which forms a cutting line on one side adjacent to the sealing line while the elevating operation by the driving unit, wherein the sealing means 11 and the cutting means 13 are integrated. A sealing / cutting portion 1 (10a) formed at the same time to form a sealing line and a cutting line at the same time with respect to the vinyl fabric (V); Sealing / cutting part 2 (10b) of the same configuration provided at intervals on one side of the sealing / cutout part 1 (10a); The upper part is fixed to both sides of the lifting portion of the sealing means 11, the lower part is provided on both sides of the fixing portion of the sealing means 11, both ends of the vinyl fabric (V) in accordance with the lifting and lowering of the sealing means (11). A gripping portion 14 for gripping; A sealing / cutting interval adjusting part 15 provided to be elevated in an intermediate portion of the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) to adjust the length of the vinyl fabric (V). And a control unit 16 for controlling the length of transport of the vinyl fabric of the winding unit 20.

Here, the sealing means 11 of the present invention, as shown in Figure 4, a heater block (11a) is built-in heater that generates heat through the power supplied by the drive unit 12 is raised and lowered; It may be configured to include; a pressing block (11b) for providing a pressing surface of the heater block (11a).

On the surface facing the crimping block 11b of the heater block 11a, a sealing surface for forming a sealing line on the vinyl fabric V may be formed.

In this case, the double-ply tube type vinyl fabric V supplied and transported between the heater block 11a and the compression block 11b may be heated and fused while being pressed / released through a lifting operation.

In this case, the lifting operation may be a heater block 11a or a crimping block 11b.

In addition, the heater block 11a may be located above the sealing means 11 and the compression block 11b may be located below the sealing means 11, and the heater block 11a may be the sealing means 11. Located at the bottom of the compression block 11b may be located at the top of the sealing means (11).

If necessary, that is, when a strong compression is required, the relatively heavy heater block 11a is lifted from the top to the bottom, and in order to reduce the load of the driving unit 12, the relatively light weight of the compression block 11b. The elevating from top to bottom means that the design can be changed selectively.

However, the present invention will be described by applying a structure for elevating the heater block (11a) from the top to the bottom in a preferred embodiment.

On the other hand, the drive unit 12 of the present invention is a power generating means (12a) for converting the rotational movement into a linear reciprocating motion in the vertical direction while eccentric rotation by a motor (not shown); An operation period 12c connected to the power generating means 12a and being lifted while being supported by the support bracket 12b; It may be configured to include; a fixed frame (12d) is fixed to one end of the operation period (12c), the lifting means to elevate the sealing means 11 in a fixed state.

At this time, the power generating means (12a) may be a cam integrally formed with a shaft connected to one end of the operation interval (12c) on the bearing eccentrically installed on the rotating shaft.

In addition, the support bracket 12b may be fixed to both sides of the main body of the apparatus and vertically penetrated blocks.

In addition, the operation period 12c may be a lifting rod (piston) connected to the shaft of the power generating means (12a).

In addition, the fixed frame 12d may be a square pipe that crosses the upper portion of the vinyl fabric V that is supplied and conveyed.

Here, in the structure in which the lifting portion of the sealing means 11 is fixed to the fixed frame 12d, the pins protruding integrally perpendicularly to the upper surface of the heater block 11a of the sealing means 11 are fixed to the fixed frame 12d. Stopper penetrates vertically, but has a stopper formed at the distal end thereof to prevent separation from the fixing frame 12d, and is formed between the upper surface of the heater block 11a of the sealing means 11 and the lower surface of the fixing frame 12d. An elastic spring can be provided in the.

In this case, not only the lifting part of the sealing means 11 can be fixed to the fixed frame 12d, but also the cushioning operation is performed during the lifting compression process for sealing.

In this case, when the power generating means 12a is eccentrically rotated by the motor, the operation interval 12c linked to the upper portion of the power generating means 12a is lifted up and supported by the support bracket 12b. The heater block 11a of the sealing means 11 fixed to the lower surface of the fixed frame 12d fixed to one end of the side 12c is lifted with respect to the crimping block 11b located below.

On the other hand, the cutting means 13 of the present invention is a sawtooth-type blade (13a) fixed to the lower space of the vinyl fabric (V) to be supplied and supplied; And a compression pad 13b provided on one side lower surface of the grip portion 14 positioned above the blade 13a with the vinyl fabric V supplied therebetween.

At this time, the pressing pad 13b is elevated to the blade portion 13a, but can only be lifted up to half of the toothed portion.

 In this case, the pressing pad 13b is lowered in the direction of the blade 13a to press the vinyl fabric V to form a cut line. At this time, since only the tooth half of the blade 13a penetrates through the pressing pad 13b, a cut line is formed. If the whole tooth portion of the blade 13a penetrates through the pressing pad 13b, the vinyl fabric Is cut off.

On the other hand, the gripping portion 14 of the present invention is provided on both sides of the lower portion of the sealing means (11) and the cutting means (13), the gripping openings 1, 2 (14a) (14b) being shot by a spring; A gripper 3 (14c) provided at one side of the heater block (11a) of the sealing means (11), and lifting and crimping while being elasticized by a spring corresponding to the gripper (1a); It is provided in the other direction of the gripper 3 (14c) provided on one side of the heater block (11a) of the sealing means 11, and is lifted and crimped corresponding to the gripper 2 (14b), but the cutting means 13 The gripper 4 (14d) is provided with a pressing pad (13b) to move up and down corresponding to the blade (13a) included in the) may be configured to include.

The grippers 1, 2 (14a) and 14b may include a square bar that is in close contact with the bottom surface of the vinyl fabric V while crossing the vinyl fabric V, and a spring that springs the square bar upward. It can be configured, the lower end can be fixed to the device body.

In addition, the gripper 3 (14c) may be configured to include a square bar that is in close contact with the upper surface of the vinyl fabric (V) while crossing the vinyl fabric (V), and the spring to the upper side of the bar to be shot upwards. The saga rod may be bolted to one side of the fixing frame 12d by a shaft passing through the spring.

In addition, the gripper 4 (14d) is a square bar that is fixed to the pressing pad (13b) that is in close contact with the upper surface of the vinyl fabric (V) while traversing the vinyl fabric (V), and shot the square bar upwards It may be configured to include a spring, wherein the square bar is one side of the bullet block 12e is fixed to the operating interval (12c) between the fixing frame 12d and the support bracket 12b by a shaft passing through the spring It may be fixed to the surface and bolted directly below the support frame 12f positioned in parallel with the fixed frame 12d.

At this time, the carbon block 12e is provided with a spring between the fixed frame 12d, the buffer of the heater block 11a and the crimp block 11b, as well as the grip 4 (14d) and grip 2 ( Buffering with 14b) can be provided simultaneously. In this case, the gripper 4 (14d) is lowered to compensate for the error between the pressing force of the heater block (11a) and the pressing block (11b) is also lowered in the process of being pressed in response to the gripper 2 (14b).

That is, when the height of the gripper 4 (14d) is adjusted so as to lower than the heater block (11a), the heater block (11a) does not provide sufficient pressing force to the compression block (11b), on the contrary, the heater block (11a) If the height is adjusted to be lower than the gripper 4 (14d), the pressing pad of the gripper 4 (14d) does not provide sufficient pressing force to the gripper 2 (14b). Perform the reward function.

At this time, the gripper 1 (14a) and the gripper 3 (14c) is located on the side in which the vinyl fabric (V) is supplied, the gripper 2 (14b) and the gripper 4 (14d) is a vinyl fabric (V) ) May be located on the side of the winding direction.

Here, the blade (13a) is located lower than the top surface of the gripper 1, 2 (14a) 14b, the vinyl positioned between the gripper 2 (14b) by the downward compression of the gripper 4 (14d) The distal line V is pushed downward and guided toward the teeth of the blade 13a so that a cut line is formed.

Thus, the blade 13a should be positioned lower than the uppermost surface of the grippers 1, 2 (14a) and 14b, so as not to interfere with the conveyed vinyl fabric (V), but also to cut the vinyl fabric (V) to form a perforation line. This is because the gripper 1 (14a) and the gripper 4 (14d) can be pushed away from the blade 13a by the vinyl fabric V stamped on the blade 13a.

On the other hand, the sealing / cutting interval adjusting unit 15 of the present invention, as shown in Figure 5, the vinyl fabric positioned between the sealing / cutting 1 (10a) and the sealing / cutting 2 (10b) An elevator 15a for directing (V) upwards, and adjusting the height thereof to vary the length of the diesel fuel V; A spacing indicator (15h) for displaying the interval (sealing between the sealing line and the cutting line and the next sealing line and the cutting line) of the vinyl fabric (V) with respect to the lifting height of the elevator (15a) in length units; It may be configured to include.

At this time, the elevator (15a) is a vertical guide rod (15b); A lead screw 15c disposed parallel to the guide rod 15b at intervals; A lifting body 15d supported by the guide rod 15b and engaged with the lead screw 15c to move up and down along the lead screw 15c by a handle operation; An induction roller 15e which is arranged in the lifting body 15d to elevate the position of the vinyl fabric V; The vinyl fabric V drawn out through the sealing / cutting section 1 (10a) to the guide roller 15e and the vinyl fabric V via the roller 1 (15f ') and the guide roller 15e. And a roller 2 (15f ") leading to the sealing / cutting section 2 (10b); a display opening (15g) displaying a lifting position on the interval display (15h).

The elevator 15a may be provided in a pair symmetrically in a direction crossing the vinyl fabric (V).

In addition, the interval indicator 15h may be a ruler provided vertically on one side of the elevator 15a. At this time, the interval indicator (15h) may be a ruler 1/2 (for example 10mm is 5mm) of the size of a conventional ruler, the installation position, that is, the position of the start point of the scale is the seal / cutout 1 (10a) Length to roller 1 (15f '), length corresponding to circumference 1/4 of roller 1 (15f'), length corresponding to circumference 1/2 of guide roller 15e, and roller 2 (15f ") It is positioned at a certain height in the horizontally running position of the vinyl fabric V, taking into account the length corresponding to the circumferential ratio of 1/4 and the length of the roller 2 (15f ") to the sealing / cutting portion 2 (10b). Can be done.

The reason for this is that the sum of the lengths also includes the length of the vinyl fabric V positioned between the sealing / cutting part 1 (10a) and the sealing / cutting part (2b).

That is, the sum of the sum of the lengths and the length from the roller 1 (15f ') to the guide roller 1e and the length from the guide roller 15e to the roller 2 (15f ") is a seal / cutout portion 1 (10a). This is because it corresponds to the total length of the vinyl fabric (V) located between the c) and the sealing / cutting part 2 (10b).

 As a result, since the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) have the same length with respect to the guide roller (15e), the scale of the interval indicator (15h) is the scale of the ordinary ruler It is preferable to set it as 1/2 with respect to.

On the other hand, in the present invention, the control unit 16 transfers the winding part to transfer 2/3 of the length of the vinyl fabric V from the sealing / cutting part 1 (10a) to the sealing / cutting part 2 (10b). It may include a controller for controlling (20).

Then, it can be processed into a rolled plastic bag, forming a sealing line and a perforation line at a predetermined interval on the vinyl fabric (V).

For example, if you want to continuously process the rolled plastic bag with a 300mm interval, the length of the vinyl fabric (V) located between the sealing / cutout 1 (10a) and the sealing cutout 2 (10b) is set to 900mm, The winding unit 20 controlled by the controller 16 transfers the vinyl fabric V by 600 mm.

As described above, the length of the vinyl fabric V positioned between the sealing / cutting part 1 (10a) and the sealing cutting part 2 (10b) is 900 mm, and the winding part 20 controlled by the controller 16 is The reason for transferring the vinyl fabric V by 600 mm is to prevent the sealing / cutting portion 2 (10b) from re-taking the sealing line and the cutting line taken from the sealing / cutting portion 1 (10a).

Referring to the operation of the present invention configured as described above are as follows.

First, the present invention is pulled while the vinyl fabric (V) wound on the supply unit is wound by the winding unit 20, the sealing / cutting unit 1 (10a) and the sealing / cutting interval adjusting unit 15 and the sealing / cutting unit 2 Continuous conveyance is supplied while sequentially passing through 10b.

Here, the vinyl fabric (V) forms a sealing line and a cutting line at a predetermined interval while the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) interlock with each other.

In this case, the lifting and lowering operations of the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) are as shown in FIGS. 6 and 7.

First, when the cam, which is the power generating means 12a, is eccentrically rotated, the operation rod 12c connected to the upper side of the power generating means 12a is lowered while being supported by the support bracket 12b.

When the operation 12c is lowered as described above, the fixed frame 12d fixed to the upper end of the operation is lowered, and eventually the heater block 11a of the sealing means 11 fixed below the fixed frame 12d. This will descend.

In this process, the grippers 3 14c and the grippers 4 14d fixed to both sides of the heater block 11a constituting the saling means 11 are lowered accordingly.

The grippers 3 (14c) and grippers 4 (14d), which are lowered as described above, are pushed downward on both ends of the vinyl fabric (V), that is, the supply part and the take-up feeder part. To 14b).

That is, by holding both the vinyl material (V) in the outward direction of the sealing means 11 and the cutting means 13 during the formation of the sealing line and the cutting line, it is gripped tightly so that the vinyl fabric (V) does not sag. The far end (V) is guided while pushing toward the blade (13a) side of the cutting means (13).

In this process, the heater block 11a is heat-sealed while pressing the vinyl fabric V on the crimping block 11b, and the sealing block 11a is pressed while pressing the vinyl fabric V in the direction of the blade 13a. To form a perforation line.

At this time, between the sealing / cutout part 1 (10a) and the sealing / cutout part 2 (10b) to form a sealing line and cutting line at a predetermined interval on the vinyl fabric (V), while the sealing / to adjust the width of the predetermined interval The cutting interval adjusting part 15 is provided as mentioned above.

As shown in FIGS. 8 and 9, the length of the rolled plastic bag is adjusted by adjusting the length of the vinyl fabric V between the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) while raising and lowering. To adjust.

That is, as shown in FIG. 8, when the guide roller 15e portion of the elevator 15a of the sealing / cutting interval adjusting unit 15 rises, between the sealing / cutting section 1 (10a) and the sealing / cutting section 2 (10b). The length of the vinyl fabric (V) can be lengthened to lengthen the length of the rolled plastic bag, and when the guide roller (15e) is lowered, the vinyl fabric between the sealing / cutting 1 (10a) and the sealing / cutting 2 (10b). The length of (V) is shortened and the length of a roll plastic bag can be lengthened.

The criterion for determining the length of the vinyl fabric V between the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) is as shown, the cutting means 13 of the sealing / cutting part 1 (10a). ) Is the sum of the length of the "A" point at which is located, the "B" point at the highest point of the guide roller 15e, and the "C" point at which the cutting means 13 of the sealing / cutting part 2 (10b) are located. .

At this time, the length of the "B" point in the "A" point and the "C" point in the "B" point is the same.

Therefore, the scale of the interval indicator 15h is 1/2 as compared with the scale of a normal ruler.

At this time, the installation position of the interval indicator 15h, that is, the starting point position of the scale, is the length from the sealing / cutting portion 1 (10a) to the roller 1 (15f ') and the circumferential ratio of the roller 1 (15f') 1 /. The length corresponding to 4, the length corresponding to the circumferential ratio 1/2 of the guide roller 15e, the length corresponding to the circumferential ratio 1/4 of the roller 2 (15f "), and the sealing / cutting off the roller 2 (15f"). In consideration of the length of the sum up to the second (10b), it may be located at a certain height in the horizontal progress position of the vinyl fabric (V).

The reason for this is that the sum of the lengths also includes the length of the vinyl fabric (V) located between the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b), the length being invariant. Since only the length by the lifting and lowering of the guide roller 15e is variable, only the variable length is indicated by the scale.

That is, the length from the sealing / cutting part 1 (10a) to the roller 1 (15f '), the length corresponding to the circumferential ratio 1/4 of the roller 1 (15f'), and the circumference of the guide roller (15e) 1/2 The scale corresponding to the sum of the length corresponding to the circumferential ratio 1/4 of the roller 2 (15f ") and the length from the roller 2 (15f") to the sealing / cutting part 2 (10b) is zero. If the reference point is assumed, and the guide roller 15e moves up and down, only the variable length is checked with a scale, and the length of the vinyl fabric V between the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) is determined. You can check it.

In this manner, the length of the vinyl fabric V between the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) is indicated by the interval display part 15h indicated by the display part 15g provided in the lifting body 15d. You can check it with the scale of.

Thus, the feeding value of the winding part 20 is set through the control part 16 in the state which adjusted the length of the vinyl fabric V between the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b).

At this time, the feeding value is set to transfer 2/3 of the length of the vinyl fabric V from the sealing / cutting part 1 (10a) to the sealing / cutting part 2 (10b).

For example, assuming that the length of the vinyl fabric V positioned between the sealing / cutting part 1 (10a) and the sealing cutting part 2 (10b) is set to 900 mm, and the desired length of the rolled plastic bag is 300 mm, The winding unit 20 is set and controlled by the controller 16 to transfer the vinyl fabric V by 600 mm.

As described above, the length of the vinyl fabric V positioned between the sealing / cutting part 1 (10a) and the sealing cutting part 2 (10b) is 900 mm, and the winding part 20 controlled by the controller 16 is The reason for transferring the vinyl fabric V by 600 mm is to prevent the sealing / cutting portion 2 (10b) from re-taking the sealing line and the cutting line taken from the sealing / cutting portion 1 (10a).

That is, as shown in FIG. 10, the sealing / cutting part 1 (10a) forms a sealing line and a cutting line at the left part of the vinyl fabric V, and the sealing / cutting part 2 ( 10b) forms a sealing line and a cut line.

Subsequently, after the winding unit 20 transfers 600 mm while winding the vinyl fabric V by the control signal of the controller 16, as shown in FIG. 11, the sealing / cutting unit 1 (10a) again. ) And the sealing / cutting part 2 (10b) form a sealing line and a cutting line at the respective positions.

Subsequently, after the winding unit 20 transfers 600 mm by winding the vinyl fabric V by the control signal of the controller 16, as shown in FIG. 12, the sealing / cutting unit 1 (10a) is again present. ) And the sealing / cutting part 2 (10b) form a sealing line and a cutting line at respective positions.

Then, the sealing / cutting part 1 (10a) and the sealing / cutting part 2 (10b) do not form the sealing line and the cutting line at the same position, but form the sealing line and the cutting line at 300 mm intervals, and this state is continuously You can iterate over and over again.

Such a rollback is wound up to the branch pipe which rotates by the winding-up part 20, and is provided to a consumer.
