In this case, the packaging means 1 includes a film guide roll 11, a film folding guide 12, a vertical seal mechanism 13, a horizontal seal mechanism 14, and a cutter mechanism 15.

  The film guide roll 11 is guided from the roll-shaped packaging film F, which is detachably attached to a holding roll 11a provided on a machine base (not shown), to the film folding guide 12. In addition, the packaging film F can apply what can be heat-sealed (heat-welded) like the laminated body which consists of nylon and low density polyethylene. In addition, the packaging film F is previously wound in a roll shape, and in this case, the belt-shaped packaging film F can be sent out by being drawn out by the vertical seal mechanism 13.

  The film folding guide 12 forms a bag in half along the longitudinal direction of the packaging film F guided by the film guide roll 11 and transfers the packaging film F to the vertical sealing mechanism 13 in this state.

  The vertical seal mechanism 13 is provided along a drive means 13a composed of a servomotor, a vertical seal roll part 13b which is provided as a pair and is rotationally driven by the drive means 13a, and along the outer periphery of each vertical seal roll part 13b. A vertical seal body 13c and an electric heater (not shown) provided inside each vertical seal roll portion 13b are provided. The vertical sealing mechanism 13 heat-seals in the vertical direction while extending the opening side and the folding side of the packaging film F folded in two by the film folding guide 12 so that the vertical sealing body 3c sandwiches it, thereby forming the vertical sealing portion Fv. A cylindrical bag-shaped packaging film F is obtained.

  The horizontal seal mechanism 14 includes a drive unit 14a composed of a servo motor, a pair of opposed side seal rollers 14b that are rotationally driven by the drive unit 14a, and a horizontal seal body 14c provided in each horizontal seal roll unit 14b. And an electric heater (not shown) provided inside each horizontal seal roll portion 14b.

  In addition, the horizontal sealing mechanism 14 is a cylinder in which a horizontal sealing portion Fh serving as a bottom portion of the packaging bag P is formed and one side is opened by thermally sealing the bag-making film obtained by the vertical sealing mechanism 13 in the horizontal direction. A wrapping film. Further, the horizontal sealing mechanism 14 is filled with the contents W by the filling means 2 and further fed with the packaging film F by the vertical sealing mechanism 13, and then the bag of the packaging film by the horizontal sealing body 14c of the horizontal sealing roll portion 14b. The mouth side is heat-sealed to form a horizontal seal portion Fh, and the contents W are sealed. Therefore, a continuous packaging bag continuous in the vertical direction is formed.

  The horizontal sealing portion Fh of the bag-making film is provided with a cutter mechanism 15, a fixed blade body and a rotary blade body (not shown), and the vertical seal mechanism 13 and the horizontal seal mechanism 14 are formed with the vertical seal portion Fv and the horizontal seal portion Fh. Individual packaging bags P are obtained by cutting the intermediate portion. The cutter mechanism 15 is driven to rotate the rotary blade body by a driving means 15a comprising a servo motor.

  The filling means 2 can intermittently discharge the contents W by a predetermined amount into a cylindrical packaging film F, one of which is opened by heat sealing of the vertical and horizontal sealing mechanisms 13 and 14. As shown in FIG. 2, the filling unit 2 includes a hopper portion 21, a valve chamber 22, a nozzle portion 23, and a suction / pressure feeding portion 24.

  The hopper portion 21 is provided at the upper part of the valve chamber 22 so as to communicate with the valve chamber 22 and is for allowing a certain amount of contents W to be stored and supplied. Moreover, the hopper part 21 can store the content W while stirring it by providing a stirring means (not shown) inside.

  The valve chamber 22 is provided with a rotor body 22a that can be rotated forward and backward by using appropriate means such as air pressure control or a servo motor as a drive source, and the movement direction of the contents W is switched by the operation of the rotor body 22a. To do. For example, as shown in FIG. 2, the rotor body 22 a closes the communication part to the nozzle part 23 side and communicates the hopper part 21 and the suction / pressure feeding part 24 via the valve chamber 22. (Hereinafter, referred to as a suckable position), or as shown in FIG. 3, the communicating portion to the hopper portion 21 side is closed and the suction / pressure feeding portion 24 and the nozzle portion 23 are in communication with each other via the valve chamber 22 ( Hereinafter, it can be switched so as to be in a position capable of being pumped).

  The nozzle portion 23 communicates with the valve chamber 22, and when the rotor body 22 a is at the pressure feedable position, the content W pumped by the suction / pressure feed portion 24 is transferred between the vertical seal mechanism 13 and the horizontal seal mechanism 14. It is formed in a tubular shape so that it can be guided and filled into the packaging film F transferred to the container.

  The suction / pressure feeding unit 24 includes a cylinder 24a communicating with the valve chamber 22 and a piston 24b that moves in the cylinder 24a by a driving means such as a servo motor.

  The suction / pumping unit 24 can suck the contents W into the cylinder 24a by the suction operation of the piston 24b when the rotational position of the rotor body 22a is in the suckable position.

  Further, the suction / pumping unit 24 can pump a predetermined amount of the contents W in the cylinder 24a to the nozzle unit 23 side when the rotational position of the rotor body 22a is at the pumpable position. . When filling the low-viscosity contents W, a so-called suction operation is performed after the pumping operation in order to prevent the contents W from dripping from the nozzle portion 23 after the pumping operation by the piston 24b is completed. A suckback process can also be performed.

  The filling and packaging apparatus also includes control means connected to the driving means and setting means 3 of the packaging means 1 and the filling means 2. As the control means, a microcomputer can be applied, and each drive means can be driven and controlled according to the packaging conditions and filling conditions by the setting means 3. For example, as shown in FIG. 4, a filling start signal is output based on a lateral seal start signal (packaging timing) to the lateral seal mechanism 13, and after the filling start signal is output, the rotational position (suctionable position) of the rotor body 22a. And the operation of switching the pressure feedable position), confirming that the pressure feedable position has been reached, and performing control to feed the contents W by the piston 24b. Further, when the pumping of the contents W is completed, the rotational position of the rotor body 22a is driven and controlled, and it is confirmed that it has become a suckable position, and the piston 24b is driven to suck the contents W of the hopper 21. Control.

  The setting means 3 can be applied with a touch panel that has a display screen and can be set and input by an operator's fingertip operation, and can perform various settings of the packaging means 1 and the filling means 2 in the filling and packaging apparatus. The setting means 3 can perform various displays and setting inputs by switching the display contents. For example, as shown in FIG. 5, the packaging conditions set separately on the filling condition setting screen displayed on the touch panel The production speed setting value 3a showing the same value as above, and various setting values 3b such as the filling amount, filling speed, and suction speed related to the filling conditions can be set numerically. The setting means 3 is connected to a circuit board or wiring having control means (not shown).

  Moreover, every time the setting means 3 inputs various set values and completes the setting on the filling condition setting screen, the setting means 3 calculates whether or not it is within a range that can be appropriately produced based on the set values. In this case, the production time t1 of each packaging bag P and the filling process time that can be predicted from various set values related to the filling process (from the start of the rotation of the rotor body 22a to the pumpable position, the content W of the piston 24b) The time until the suction operation is completed) t2, and if the filling processing time t2 is longer than the production time t1 of each packaging bag P, it is determined that appropriate filling and packaging cannot be performed, and a change of the set value is urged. Display. In addition, when performing a suck back process, an appropriate filling process time can be calculated by calculating this processing time in addition to the filling process time. Therefore, it is possible to prevent filling and wrapping due to inappropriate settings by making a certain prediction before trial operation of the filling and wrapping apparatus.

  Further, for example, as shown in FIG. 6, the control means monitors various control signals such as a filling start signal when the respective driving means are controlled for filling and packaging. In this case, the control means determines whether or not a filling start signal has been issued (step S1), and if a filling start signal has been issued, determines whether or not the filling process is in progress (step S2). . In this case, when determining whether or not the filling process is in progress, the determination is made by confirming whether or not the suction operation is completed by the piston 24b by detecting the drive signal of the drive means of the piston 24b. .

  When it is determined in step S1 or S2 that the filling start signal has been issued during the filling process, the control means controls the driving means of the packaging means and the filling means to stop (step S3), and is set. On the display screen of the means 3, a display for prompting a change in setting of the packaging condition or filling condition is performed (step S4). The operator can take out a defective packaging bag P such as an insufficient filling amount, change the set value as appropriate, and then restart the filling with a more appropriate set value.

  In Steps 1 and 2, when it is determined that a filling start signal is issued during the filling process, the rotor body 22a and the piston 24b are driven and controlled to perform the next filling process as usual, and the inside of the packaging film F Can be filled with a predetermined amount of contents W, and preparations for filling can be made (step S5).

  For example, when filling and wrapping the highly viscous content W, a load may be applied to the rotation of the rotor body 22a, the pressure feeding or suction operation by the piston 24b, and the like, which may be longer than the predicted filling processing time. is there. Even in this case, by repeating the processing from step S1 to step S5, the filling and packaging can be automatically stopped and defective packaging bags can be removed to the minimum, and the setting means 3 displays the appropriate It is possible to prompt the operator to fill and pack with various set values.

  The filling and packaging apparatus includes a packaging unit 1 that continuously forms the packaging bag P by heat-sealing the packaging film F, and a filling start signal that is issued according to the packaging timing of the packaging unit 1. Filling means 2 for supplying fluid contents W intermittently to each other, setting means 3 for setting the packaging conditions of the packaging means 1 and the filling conditions of the filling means 2, and during the filling process by the filling means 2 And a control means for determining whether or not there is a next filling start signal. Therefore, since it is possible to determine filling and packaging under inappropriate conditions, it is possible to reduce troublesome trial operation and filling amount measurement work for the operator, and easily prevent production of defective packaging bags. .

  Further, when it is determined that there is a next filling start signal during the filling process by the filling means 2, the control means stops the packaging means 1 and the filling means 2 and uses the setting means 3 to set the packaging condition or the By performing the display prompting the change of the filling conditions, it is possible to minimize the consumption of the packaging film and the contents due to the defective product and to easily remove the defective product. In addition, by prompting the user to change the set value, filling and packaging due to inappropriate conditions can be easily prevented.

  Further, the setting means 3 calculates the filling processing time t2 based on various set values, and when the filling processing time is longer than the production time t1 per packaging bag P, the packaging condition or the filling condition is set. Display a prompt to change. Accordingly, it is possible to determine that the condition is inappropriate before the trial run and to prompt the user to change the set value, so that filling and packaging due to the inappropriate condition can be easily prevented.
