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. Further, the horizontal seal mechanism 14 includes horizontal seal detection means (not shown) including a proximity sensor and a transmission type sensor in order to detect the timing of heat sealing by the horizontal seal body 14c.

  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 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. 4, in the filling condition setting screen displayed on the touch panel, filling according to the production speed is possible. The quantity, filling speed, suction speed, etc. can be set numerically. The setting unit 3 is connected to various driving units via a circuit board or wiring having a control unit (not shown), and can perform drive control based on various settings.

  In this filling condition setting screen, an approximate margin time (margin time) 3a calculated based on various setting values related to the filling process and a separately set production speed is displayed together with various setting values related to the filling process. The estimated margin time 3a is determined from the production time of each packaging bag P determined from the production speed to the filling processing time based on the filling conditions (from the start of the rotation of the rotor body 22a to the pressure feedable position, the contents W by the piston 24b). The time to complete the suction operation is subtracted. In addition, when performing a suckback process, the rough allowance time 3a can be calculated by calculating this processing time in addition to the filling processing time.

  Since the operator can set the filling conditions while checking the numerical values using the approximate margin time 3a as a guideline, it is possible to reduce the work of judging whether or not filling is possible by a trial run or making a judgment by himself. .

  Also, during trial operation and production operation, the input time of various sensors and the output time of control signals are sampled and stored as past data, and an actual measurement margin time (margin time) 3b based on the actual filling processing time is calculated and displayed. can do. For example, as shown in FIG. 5, by displaying the measured margin time 3b together with the time chart 3c based on the actual past data for the process related to the filling process, the adjustment location can be visually determined quickly, It will be convenient for the person. In this case, the filling start signal based on the signal from the horizontal seal detection means provided in the horizontal seal mechanism 13, the rotational position of the rotor body 22a (switching operation between the suckable position and the pressure feedable position), and the pressure feed of the piston 24b. The suction operation is sampled and displayed on the time chart 3c.

  For example, when filling and wrapping the highly viscous content W, a load is applied to the rotation of the rotor body 22a, the pumping and suctioning operation by the piston 24b, etc. It may become long. Also in this case, the set value of the filling condition can be easily adjusted using the actual measurement allowance time 3b as a guide. In addition, when setting the filling conditions in consideration of the viscosity change due to the temperature change of the contents W, the measured margin time 3b and the approximate margin time 3a can be numerically confirmed, so that the adjustment work is easy for the operator. Can be.

  Such a filling and packaging apparatus includes a packaging means 1 for continuously forming a packaging bag P by heat-sealing the packaging film F, and a filling means for intermittently supplying a flowable content W into the packaging bag P. 2 and setting means 3 for setting the packaging conditions of the packaging means 1 and the filling conditions of the filling means 2, wherein the setting means 3 includes the packaging conditions (packaging bags P The adjustable range of the filling condition (filling processing time) with respect to the production time per bag) is displayed as margin times 3a and 3b. Therefore, it becomes a filling and packaging apparatus that allows an operator to easily set appropriate filling conditions by checking the margin times 3a and 3b displayed numerically.

  Also, the approximate margin time 3a is calculated from the difference between the production time per bag P and the filling time of the contents W, so that the approximate margin time 3a can be confirmed numerically before operation. Therefore, it is possible to easily set an appropriate filling condition by an operator.

  In addition, since the setting means 3 displays the time chart 3c relating to the operation of the filling means 2 together with the margin times 3a and 3b, the adjustment location can be visually determined. Filling and packaging can be performed.

  Further, the setting means 3 samples the filling process time when the last filling and packaging process is actually performed, calculates the actual margin time 3b based on this filling process time, and displays the actual filling process time. Even if it is different from the filling processing time calculated by calculation, the actual margin time 3b can be numerically confirmed. Therefore, since it can be determined how much adjustment is required, the adjustment work is simplified.
