Forming a packaging bag. In order to obtain such a packaging bag, there is known a filling and packaging apparatus for automatically feeding out a film from a film roll wound in a roll shape and packing the film in a three-sided or four-sided seal. 1 and Patent Document 2).

[0003] Generally, as a filling and packaging apparatus for producing a packaging bag with a three-sided or four-sided seal, a pair of holding frames are provided on a side portion of a machine base (main body), and the holding frames are formed into a roll shape. The original film on which the film is wound is held detachably and replaceably. In addition, a film guide mechanism and a film folding mechanism are disposed on the upper part of the machine, and a vertical seal mechanism, a horizontal seal mechanism and a cutter mechanism are provided on the front part of the machine from the upper side. The filling and packaging apparatus guides the film from the film source through the film guiding mechanism and the film folding mechanism, and the opening end of the folded film folded in two along the longitudinal direction of the film by the film folding mechanism. Alternatively, the open end and the folded side are vertically sealed by a pair of vertical seal rolls provided in the vertical seal mechanism. The filling and packaging apparatus feeds the tubular packaging film, which has been vertically sealed by the vertical sealing mechanism, while sandwiching the packaging film, and horizontally wraps the packaging film by a pair of horizontal sealing rolls provided in the horizontal sealing mechanism. Seal horizontally in the direction. And the filling and packaging apparatus forms a bottom portion that becomes a packaging bag by the horizontal sealing mechanism, The packaging film formed into a bottomed cylindrical shape is filled with an object to be packaged (contents) such as a sauce and soy sauce by a filling mechanism, for example, and the film is further fed and the horizontal sealing mechanism of the horizontal sealing mechanism is again fed. A continuous filling packaging bag is formed by horizontally sealing the bag opening side of the packaging film with the roll portion to seal the packaged object. The filling and packaging apparatus obtains individual packaging bags by cutting the intermediate portion of the horizontal sealing portion of the continuous filling and packaging bags with the cutter mechanism.

[0005] Incidentally, when changing the filling amount of the granular material, it is necessary to replace or set the volume meter provided on the rotary disk in accordance with the supply amount. However, there is a problem that it takes time and the like. Further, since the powdery material is intermittently supplied to the filling and packaging device by using the rotating mechanism of a rotating disk, the production efficiency cannot be increased, and the horizontal sealing mechanism cannot be improved. It is also difficult to adjust the timing of supplying the granular material in accordance with the horizontal seal timing.In some cases, there is a problem that, at the horizontal seal portion of the packaging bag, the bag is formed while the granular material is being caught. . In addition, a part of the powder material stays in the weighing box or the charging chute for sending the powder material to the packaging bag, and stays after the filling of the powder material is stopped. A part of the granules is spilled on the packaging film to form the package. When the bag opening of the film is horizontally sealed, there is a problem that a part of the granular material may be inserted and a sealing failure may occur.

[0006] Therefore, the present invention has been made in view of the above-described problems, and even when the packaged object is a granular material, the supply amount and supply timing of the granular material are arbitrarily changed.

Since the supply amount of the granular material can be arbitrarily changed without changing the mechanical configuration, the conversion and setting work accompanying the change can be simplified, and the productivity can be improved. Further, as compared with the conventional method, the charging start timing of the powder and granules can be set only by adjusting the driving start timing of the screw conveyor member based on the input of the detection signal from the horizontal seal detecting means.

Next, the setting means 11 will be described in detail with reference to FIG. The setting means 11 is composed of a touch panel, and sets the drive start timing (operation timing) of the screw conveyor 6c3 to supply the powder K in accordance with the timing of the horizontal sealing of the horizontal sealing mechanism 4. Adjustment switch for controlling the forward rotation (rotation amount) of the screw conveyor 6c3 of the granular material supply mechanism 6 to adjust the supply amount of the granular material K. 12b, a forward rotation speed adjustment item switch 12c for setting the rotation speed of the screw conveyor 6c3, and a scraper 6a3 for setting the conveyance speed of the screw conveyor 6a2 provided in the hopper section 6a and stirring the granular material K. An adjustment switch operating section 12 is provided which includes a transport and stirring motor (hereinafter referred to as a transport and agitating motor) adjustment item switch 12d for setting a rotation speed. The adjustment switch operation unit 12 has a filling correction item switch 12a, a normal rotation amount adjustment item switch 12b, and a normal rotation speed adjustment item switch 12c, which are adapted to the supply condition of the powder K, that is, the packaging form for each type.

It depends on the production conditions consisting of the rotation speed of the conveyor 6c3. The setting means 11 is not limited to the above-described configuration of the setting means 11 as long as it can set at least the production conditions.

Next, the processing operation of the control means 10 will be described in detail with reference to FIG. Delivered, and the horizontal sealing interval (sealing) predetermined by the horizontal sealing mechanism 4 (Rubich) will be described on the assumption that the horizontal sealing is performed.

After the power switch of the system in the filling and packaging apparatus A is turned “ON”, the control means 10 switches the signal input from a dedicated switch (not shown in the figure) for which filling is permitted from “ΔN” to “OFF”. Until then (time Tx), the processing operation described later is executed (FIG. 4 (a)).

The control means 10 inputs a horizontal seal timing signal (hereinafter, referred to as a horizontal seal signal) S from the horizontal seal detection means 4d input at a predetermined cycle T1 (FIG. 4 (b)), and outputs the horizontal seal signal S Based on the input (rising of the pulse signal), the filling correction item (filling correction item switch 1 la) of the setting means 11, the forward rotation amount adjustment item (forward rotation amount adjustment item switch 1 lb), and the forward rotation speed The rotation of the screw conveyor 6c3 of the granular material supply mechanism 6 is controlled by the time tl, the rotation amount, and the rotation speed set in advance in the degree adjustment item (the forward rotation speed adjustment item switch 11c) (FIG. 4 (c)).

When the time tl in the filling correction item is "0", the screw conveyor 6c3 rotates substantially simultaneously with the input of the horizontal seal signal S (ignoring the delay time of the electrical control and the mechanical control), As the time tl becomes longer, the rotation start time of the screw conveyor 6c3, that is, the supply time of the powder K is delayed. Needless to say, this depends on the type of the powder K (powder type or slightly moist). An internal counter provided in the control means 10 is used for measuring time.

On the other hand, the control means 10 controls the hopper section 6a and the transport trough section 6b of the granular material supply mechanism 6 as follows.

[0058] The control means 10 detects the staying state of the granular material K in the receiving portion 6cl provided in the transport pipe 6c2 of the granular material supply mechanism 6 by the granular material detecting means 6d, and detects the staying state of the granular material K. The driving means 6al of the screw conveyor 6a2 and the scraper 6a3 is controlled based on the control. That is, when the state of retention of the granular material K is smaller than a predetermined amount (when the signal input by the granular material detection means 6d is “〇FF”) (FIG. 4D), the control means 10 The screw conveyor 6a2 and the scraper 6a3 provided in the inside are controlled by the rotation speed based on the voltage value preset in the carrying and stirring motor adjustment items of the setting means 11 (the carrying and stirring motor adjustment item switch 1 Id). One Then, it is immediately rotated via the driving means 6al to supply a predetermined amount of the granular material K to the transport trough 6b. Further, when the state of retention of the granular material K in the receiving unit 6cl is larger than a predetermined amount (when the signal input by the granular material detecting means 6d is “ON”) (FIG. 4 (d)), The rotation drive of the screw conveyor 6a2 and the scraper 6a3 is stopped after a lapse of a predetermined time t2 from the “ON” of the input signal, and the driving means 6al is controlled so as to stop the supply of the granular material K (FIG. 4 (e)). It is desirable that the rotation speed based on the above-mentioned transport and stirring motor adjustment items be set in accordance with the type of the granular material K.

[0059] The control means 10 controls the vibration generator 6b2 provided in the transport trough section 6b so as to interlock with the driving means 6al for controlling the starry conveyor 6a2 and the scraper 6a3. During the time Ty during which the 6a2 and the scraper 6a3 operate, the vibration generator 6b2 is operated to apply vibration to the transport conveyor 6bl, and the granular material K is transported and supplied to the receiving unit 6cl side, and the screw conveyor 6a2 and the scraper 6a3. When is not operating, the vibration generator 6b2 is not operated, and the granular material K is not transported and supplied to the receiving unit 6cl (FIG. 4 (f)).

Within the time Ty during which the vibration generator 6b2 of the section 6b operates, the drive control is performed so as to intermittently apply vibration to the hopper section 6a at a predetermined cycle T2, and the powder K is discharged from the hopper section 6a. In addition to supplementing the feeding operation, it compensates for the stirring action of the powder K in the hopper 6a (Fig. 4 (g)).

A drive signal is output to an electromagnetic valve 6c7, which is a driving means of the knocker member 6c6 (FIG. 7 (d)), and pneumatic pressure is supplied to the cylinder of the knocker member 6c6 to move the hammer back and forth to transfer the pipe. Vibration is imparted by squeezing at least one or more hits around the carry-out port 6c5 of the 6c, and the powder K retained around the carry-out port 6c5 is carried out toward the input chute 5a. Further, after detecting the completion of the operation of the screw conveyer 6c3 in FIG. 7 (c), the control means 10 inserts after time t4, that is, after the screw conveyer 6c3 is stopped and the knocker member 6c6 starts driving. A drive signal is output to a solenoid valve 5d, which is a driving means of a knocker member 5c provided near the chute 5a (FIG. 7 (e)), and air is supplied to the cylinder of the knocker member 5c to remove the hammer. By moving the feeding chute 5a back and forth and applying at least one or more blows to the input chute 5a, vibration is imparted and the powder K retained in the feeding chute 5a is carried out toward the bag making film. Note that the time t3 and the time t4 may be the same time, and the knocker member 6c6 for the carry-out port 6c5 and the knocker member 5c for the input chute 5a may be configured to be driven synchronously. .
