[0021] In the figure, the overall outline of the filling and packaging machine is configured such that a film roll R wound with a packaging film F is mounted and supported on a holding frame 1 provided on the side of the filling and packaging machine. The packaging film F drawn and guided from the film roll R is guided to the upper side of the filling and packaging machine through the film guide mechanism 2 while being given a predetermined tension, and is guided to the upper side of the filling and packaging machine. The film F fed out and guided to the upper side of the filling and packaging machine by 2 is folded in half along the longitudinal direction of the packaging film F by the film folding mechanism 3 and is guided to be drawn out downward. Yes.

In the first embodiment, the bi-fold film F drawn out and conveyed downward is guided to the vertical seal mechanism 4. The vertical seal mechanism 4 is rotatably provided by a drive means Ml that also has a servo motor force, and the film F folded back in half by a vertical seal roll member 4B provided on the outer periphery of a pair of opposed vertical seal rolls 4A. The vertical seal FH is formed by heat-sealing in the vertical direction, and then heat-sealed by the horizontal seal mechanism 5 arranged below the vertical seal mechanism 4, that is, downstream of the film F being conveyed. The horizontal seal FS location is formed.

[0023] The horizontal seal mechanism 5 is rotatably provided by, for example, a drive means M2 having a servo motor force, and is provided by a horizontal seal member 5B provided along the width direction of the outer periphery of a pair of opposed horizontal seal rolls 5A. A horizontal seal FS point is formed on the packaging film F by heat-sealing at a predetermined interval in the horizontal direction, and the bottom part is formed into a bottomed cylindrical shape that becomes the packaging bag P by this horizontal seal FS point. The packaging film F formed in the bottom cylindrical shape is filled with the contents W from the filling nozzle 6A of the filling mechanism 6 through the pump 6B, and then the packaging film F is fed out, and then the horizontal sealing mechanism 5 Provided on seal roll 5A The part which becomes the bag mouth part of the packaging film F is laterally heat-sealed by the lateral sealing member 5B, and the contents W are sealed by the lateral sealing FS by this lateral heat sealing, and the contents W are continuously in a continuous state. The packaging bag P filled with is continuously conveyed downward.

[0024] In this case, as the lateral seal mechanism 5, the lateral seal roll 5A of the first lateral seal mechanism and the lateral seal roll 15A of the second lateral seal mechanism are vertically moved along the longitudinal direction of the packaging film F. Two pairs of equipment are provided, and the product W filled by the filling nozzle 6A of the filling mechanism 6 is sandwiched and pushed out into the packaging film F that is fed out while being formed into a cylindrical shape by the vertical seal mechanism 4 After the horizontal seal FS by heat sealing with the horizontal seal member 5B provided on the pair of horizontal seal rolls 5A by the first horizontal seal mechanism, the horizontal seal FS is then sealed by the first horizontal seal mechanism. At the FS location, the horizontal seal member 15B provided on the horizontal seal roll 15A of the second horizontal seal mechanism is pressed again in a low temperature overheated or normal temperature condition to seal the horizontal seal FS location. The stopping state is kept good. In some cases, the second side sealing mechanism may be configured without the step of pressure sealing the side seal FS location.

[0025] The filling mechanism 6 is provided with, for example, a pump 6B for supplying the contents W. The pump 6B can be charged and supplied with the contents W by rotating the driving means M3 including a servo motor. Is provided.

[0026] Further, on the lower side of the horizontal seal mechanism 5, there is a cutter blade for all cuts that can be separated and carried out with the substantially central portion of the horizontal seal FS portion of the filling and packaging bag P in a continuous state in the vertical direction. Cutter mechanism 7 having a receiving blade is disposed, and a notch is formed with a cutting edge for forming a notch for facilitating opening of the packaging bag P between the lateral seal mechanism 5 and the cutter mechanism 7 Mechanism 8 is provided. In this embodiment, only the cutter mechanism 7 provided with a cutter blade for all cuts is provided. In some cases, the first cutter mechanism for perforating is provided, and in the subsequent processes, the first cutter mechanism is provided for all cuts. A second cutter mechanism with a cutter blade may be provided.

[0027] The cutter mechanism 7 is rotatably provided by a driving means M4 including a servo motor for rotationally driving one of the cutter blades. Is provided rotatably by driving means M5 which is a motor force for rotationally driving the blade edge for forming the notch.

By the way, for the present embodiment, a sensor for detecting the state of feeding of the film F at the position of the previous process of the vertical sealing mechanism 4, that is, a part of the film feeding mechanism 2, for example, a rotary encoder. A film feeding detection means 9 that also has force is arranged. The film feed detection means 9 is configured to output the rotation amount data accompanying the rotation drive to the control means described later as an output signal.

Next, the electrical configuration and control method in the filling and packaging machine of the present invention will be described with reference to FIG.

[0030] The main power switch 10A is for turning on and off the power of the filling and packaging machine, and is configured by setting means 10 that also has power, such as a switch operation group provided on the operation panel and a switch group of a touch panel. When the power switch 10A is turned on, a heater (not shown) for the vertical seal mechanism 4 or a heater for the horizontal seal mechanism 5 is used based on the predetermined control of the control means 11 that is a control device such as a microcomputer. It is configured so that power is supplied to electrical components such as (not shown).

[0031] In addition to the main power switch 10A, an operation start switch 10B that also operates the filling and packaging machine is provided in the setting means 10, and the operation switch 10B is turned on. Then, based on the predetermined control by the control means 11, the supply mechanism W is supplied via the filling mechanism 6 force drive means M3, or the vertical seal rolls provided in the vertical seal mechanism 4 and the horizontal seal mechanism 5 are provided. The drive means Ml, M2 of 4A and the transverse seal roll 5A and the drive means M4, M5 of the cutter mechanism 7 and the notch forming mechanism 8 are electrically operated to rotate respectively.

Therefore, in the filling and packaging machine of the present invention having the above-described constitutional force, the longitudinal seal mechanism 4 disposed downstream of the film folding mechanism 2 is folded in half by the operation of the driving means Ml. Since the folded edges (left and right edges) are sandwiched between the vertical seal roll members 4B, the vertical seal FH is applied along the vertical direction of the film F while the film F is fed out, and then the first and second The lateral seal mechanisms 5 and 15 are driven along the width direction of the outer periphery of the pair of opposed lateral seal rolls 5A and 15A by the operation of the driving means M2. The lateral seal members 5B and 15B are provided to form a lateral seal FS location on the packaging film F, thereby filling the packaging film F formed into a bottomed cylindrical shape as the driving means M3 rotates. After the contents W are filled from the filling nozzle portion 6A of the mechanism 6 via the pump 6B and then the packaging film F is sent out, the horizontal sealing member provided on the horizontal sealing roll 5A of the horizontal sealing mechanism 5 is similarly applied. The part that becomes the bag mouth of packaging film F is laterally heat-sealed by 5B, and the contents W are sealed by the lateral seal FS by this lateral heat sealing, and the notch forming mechanism 8 forms the notch by the operation of the driving means M5. The cutting edge is rotated and a notch is formed in the approximate center part (appropriate position) of the horizontal seal FS. Subsequently, the cutter mechanism 7 is driven by the driving means M4, and one of the opposing cutter blades rotates. As a result, the substantially intermediate portion of the horizontal seal portion is cut, and as a result, the packaging bags P filled with the contents W in a continuous state are separated and transported downward continuously. The The above-described operation control of the filling and packaging machine is performed by the control means 11. The control means 11 inputs movement amount data indicating the movement amount of F of the film from the film feeding detection means 9, and The position control processing in the lateral seal mechanism 5, the notch forming mechanism 8 and the cutter mechanism 7 is executed in accordance with the movement amount data.

In addition, when the operation of the filling and packaging machine is stopped, that is, when the operation switch 10B is in the OFF state, the control unit 11 stops filling the content W by the filling mechanism 6 with the OFF signal input as a base point. When the off signal is input, the side seal mechanism 5 performs the horizontal seal FS point force The process of discharging the continuous packaging bag P located between the cutter mechanism 7 from the cutter mechanism 7 Execute. That is, the control means 11 corresponds to the cutting position of the cutter mechanism 7 (substantially central portion of the lateral seal FS) from the reference position LS (substantially central portion of the lateral seal FS) corresponding to the lateral seal FS location by the lateral seal mechanism 5. After feeding the continuous length of the packaging bag P corresponding to the distance L to the position LE from the cutter mechanism 7, the feeding of the film F is controlled to be stopped. More specifically, the distance L from the reference position LS corresponding to the horizontal seal FS location by the horizontal seal mechanism 5 to the position LE corresponding to the cutting location of the cutter mechanism 7 and the horizontal seal of the continuous packaging bag P Based on the dimensions of the pitch L1 between the FS, when the filling and packaging machine is stopped. Packaging until the packaging bag P (packaging bag P with lateral seal FS) that exists between the distance L from the lateral seal mechanism 5 to the cutter mechanism 7 reaches the cutting position of the cutter mechanism 7 By calculating the number of bags P and counting this number based on the movement amount data from the film feed detection means 9, the packaging bag P positioned at the side seal FS location It can be determined that the cutting position of mechanism 7 has been reached. In the control described above, the cutting operation of the cutter mechanism 7 can be made into individual packaging bags P by enabling the cutting operation of the cutter mechanism 7 in the same manner as the normal operation, and the cutting process of the cutter mechanism 7 can be disabled after the counting process is completed. By doing so, it becomes possible to discharge the packaging bag P filled with an inappropriate amount of the content W after the filling mechanism 6 is stopped in the form of a continuous packaging bag P.

[0034] The filling and packaging machine and the driving method thereof are the longitudinal seal FH along the longitudinal direction of the film F while sandwiching the continuously transported film F by the pair of longitudinal seal roll members 4B. A sealing mechanism 4; a filling mechanism 6 for filling the contents W in the cylindrical film F which has been vertically sealed FH by the vertical sealing mechanism 4; and the bottom side of the film F and the bag mouth while feeding the cylindrical film F. The side seals are paired along the width direction of the film F. Horizontal seal roll 5A horizontal seal member 5B. When the off-signal input indicating that the operation of the filling and packaging machine is stopped is input, the transverse seal of the packaging bag P sealed with the cutter mechanism 7 that cuts the appropriate position of the FS location. When the filling of the contents W by the filling mechanism 6 is stopped and the off signal is input, at least when the transverse seal FS position force by the transverse seal mechanism 5 is also located between the cutter mechanism 7 and the continuous packaging bag P is discharged from the cutter mechanism 7.

[0035] With this configuration, the packaging bag P existing at least between the lateral seal FS position by the lateral seal mechanism 5 and the cutter mechanism 7 is fed to the cutting position of the cutter mechanism 7 and cut. This makes it possible to commercialize packaging bags P that have been handled as defective products as good products, thereby reducing the number of defective products, and increasing the productivity and control methods of filling and packaging machines. Become.

[0036] The cutter mechanism 7 is formed by individually cutting and discharging the continuous packaging bags P. [0037] Therefore, the packaging bag P that has been handled as a defective product until now can be commercialized as a non-defective product, thereby reducing the number of defective products, and a method for controlling a highly productive filling and packaging machine. It becomes.

[0038] When the film feeding of the filling and packaging machine is stopped, the vertical seal mechanism 4, the horizontal seal mechanism 5 and the cutter mechanism 7 are stopped, and the vertical seal roll member 4B of the vertical seal mechanism 4 is opened. It works.

[0039] With this configuration, the operation of the vertical seal mechanism 4, the horizontal seal mechanism 5, and the cutter mechanism 7 is stopped in accordance with the feeding of the film F when the operation that is the main power source of the filling and packaging machine is stopped. can do. In addition, the heat of the vertical seal roll member 4B of the vertical seal mechanism 4 is not transmitted directly to the film F of the packaging bag P, and the fusion layer inside the film F melts! / The problem of damaging the film F itself can be solved.

[0040] As the film feed of the filling and packaging machine is stopped, the horizontal seal member 5B of the horizontal seal roll 5A is stopped without pressing the film F when the horizontal seal mechanism 5 is stopped. It is what

[0041] With this configuration, the lateral seal member 5B of the lateral seal roll 5A does not directly contact the film F of the packaging bag P when the lateral seal mechanism 5 is stopped. The problem that the inner fusing layer itself melts and damages the film F itself can be solved.

[0042] Further, a notch forming mechanism 8 is provided on the downstream side of the vertical seal mechanism 4 to make a notch for opening at the vertical seal FS location sealed by the vertical seal mechanism 4.

[0043] By configuring in this way, at least the lateral seal FS location force by the lateral seal mechanism 5 can be notched to the packaging bag P existing between the cutter mechanism 7 and the opening of the packaging bag P can be improved. It can be carried out.

[0044] Further, as the horizontal sealing mechanism 5, a first horizontal sealing mechanism 5 that performs horizontal sealing FS in the heated state along the width direction of the film F at the bottom side and the bag mouth side of the film F; This is composed of a second horizontal seal mechanism 5 that presses and seals a portion that has been laterally sealed FS by the first horizontal seal mechanism 5 downstream from the first horizontal seal mechanism 5. .

[0045] With this configuration, the packaging bag P can be well sealed laterally. The That is, the first horizontal seal mechanism 5 performs the ironing action of the contents W and heat fusion of the horizontal seal FS locations, and further pressurizes and seals the same heat-sealed locations, whereby the horizontal seal FS The horizontal seal FS can be stabilized quickly in a short time by heat-curing the part.

[0046] Further, as the cutter mechanism 7, although not shown, a first cutter mechanism for cutting a perforated cut portion at a substantially central portion which is an appropriate position of the lateral seal FS location, and the first cutter By providing a second cutter mechanism 7 to cut the approximate center of the horizontal seal FS location at the downstream side of the mechanism, at least the horizontal seal force by the horizontal seal mechanism A perforation, which is a partial cut, is made by the first cutter mechanism at the side seal portion of the packaging bag that exists in the packaging bag, or the packaging bag is separated and carried out by a full cut by the second cutter mechanism. be able to.

[0047] In addition, as the vertical seal mechanism 4, the film F is sandwiched between at least a pair of vertical seal roll members 4B attached to the pair of vertical heat seal rolls 4A, and the vertical seal FH is used. The drawer can be guided.

[0048] With such a configuration, the vertical seal FH is formed by the pair of vertical seal roll members 4B mounted on the pair of vertical heat seal rolls 4A provided in the vertical seal mechanism 4 for feeding the film F. At the same time, film F can be sent out.

In the embodiment of the present invention, a force using a rotating mechanism as the driving means of the cutter mechanism 7 In the present invention, a cutter mechanism by a reciprocating operation may be used.
