After the arm 314 is pulled toward the proximal end and the opening of the inner bag B is sucked by the suction pad 315, the arm The opening of the inner bag B is opened by returning 314 to the original position. At this time, the bag chuck 53 of the holding jig 50 is moved inward by the bag chuck.

<Configuration-5 of Filling Unit 30 (Filling Nozzle 32)>
When the mouth of the inner bag B is opened, the support 33 is removed from the tip of the filling nozzle 32 by rotating on the plane. When the sagging receptacle 33 is removed, the filling nozzle 32 starts to descend, but filling starts before the tip of the filling nozzle 32 is inserted into the outer container P near the top opening P1 of the outer container P. At that time, the small filling is initially performed, and then the tip of the filling nozzle 32 is inserted into the outer container P and inserted to the vicinity of the bottom (the height within 10 cm from the bottom) to start the large filling. By making small filling first, even if the lower end of the inner bag B is outside the outer container P, the lower end of the inner bag B is dropped into the outer container P and the opening of the bag is steadily performed. It can be. In accordance with the first small filling, the inner bag B expands by the small filling, and the inner bag B is expanded while the holding jig 50 holds the opening of the inner bag B while the jig operating head 312 holds the opening. The holding jig 50 is raised until the lower end of the container rises from the bottom surface of the outer container P, and large filling is started. Thereby, the center line (bottom side heat seal line) of the inner bag B and the filling nozzle 32 can be aligned.

<Configuration-1 of Sealing Portion 40>
Next, the sealing part 40 will be described. As shown in FIG. 7, in addition to the second jig transfer mechanism 41 that transfers the holding jig 50 that holds the inner bag B from the opening of the outer container P onto the return path 70, the sealing part 40 includes: A deaeration mechanism 42 for removing air above the granular material or liquid filled in the inner bag B, a sealing chuck 43 for moving the inner bag B from the holding jig 50, and the inner bag B are heat-sealed. And a sealing mechanism 44. The second jig transfer mechanism 41 is only required to be installed downstream of the sealing part 40 including the sealing part 40, and is not necessarily provided in the sealing part 40, but is provided in the sealing part 40. Then, since the filling packaging machine 1 can be made into a compact design, it demonstrates as what is provided in the sealing part 40 here.

<Configuration-2 of sealing part 40>
The arrangement relationship of these elements is as follows. In the right side view in the figure, a deaeration mechanism 42 that can move up and down is located above the fixed position of the outer container P, and a seal chuck 43 that can move left and right is located on the left side of the fixed position of the outer container P. A sealing mechanism 44 that can be moved to the left and right is located on the left side of the fixed position of P and above the sealing chuck 43. A second jig transfer mechanism 41 that is movable and movable left and right is provided.

<Configuration-3 of Sealing Portion 40 (Deaeration Mechanism 42)>
The outer container P has the holding jig 50 mounted on the top opening P1 of the outer container P, the opening of the inner bag B is held by the holding jig 50, and the granular material is contained in the inner bag B. Or it is conveyed in the state filled with the liquid. In the sealing part 40, before sealing the inner bag B, the air inside the powder or liquid is deaerated, but the inner bag B in the outer container P that has been conveyed is deaerated. The mechanism 42 descends and degass the internal air above the powder or liquid. The deaeration mechanism 42 may be one that inserts a nozzle into the inner bag B and sucks it, or one that pushes out from the outer side of the inner bag B, but the former may suck in the filled powder or liquid. In view of this, the latter is preferred in this respect.

<Configuration-4 of sealing portion 40 (deaeration mechanism 42)>
For pushing out air, it is preferable to provide a pair of substantially triangular or semicircular plate portions 421 at the tip of the deaeration mechanism 42. The plate portion 421 is flexibly attached to the up and down drive so as to come into contact with the shape of the inflated inner bag B without difficulty. The descending amount of the plate portion 421 is configured to be adjustable according to the amount of powder or liquid filled in the inner bag B. Further, the amount of air to be deaerated is such that the lid of the outer container P can be closed after the mouth of the inner bag B is sealed.

<Configuration of Sealing Portion-5 (Deaeration Mechanism 42)>
When degassing, the holding jig 50 holds the opening of the inner bag B, that is, the opening is relatively with respect to the filling portion of the inner bag B filled with powder or liquid. Since it is in the lifted state, air can be extracted without disturbing the opening of the inner bag B to be sealed in the next stage.

<Configuration-6 of Sealing Portion 40 (Sealing Mechanism 44)>
When the degassing from the inner bag B is completed, the sealing chuck 43 advances toward the inner bag B (to the right in the drawing). Then, the opening of the inner bag B is held around the position held by the holding jig 50 (see FIG. 8). When the sealing chuck 43 holds the opening of the inner bag B, the holding jig 50 opens the opening of the inner bag B held by the bag chuck 53, and the bag guide 54 spreads. The holding jig 50 is retracted from the fixed position of the outer container P by the second jig transfer mechanism 41. The seal chuck 43 receives the inner bag B as it is when the bag chuck 53 pulls the opening left and right (longitudinal direction of the opening) when the opening of the inner bag B is changed from the holding jig 50, or Further, it may be pulled left and right.

<Configuration 7 of Sealing Portion 40 (Sealing Mechanism 44)>
As shown in FIG. 8, the sealing chuck 43 is configured such that a pair of U-shaped holding portions 431 face each other so as not to interfere with the bag chuck 53 and the sealing mechanism 44. The inner bag B passed from the bag chuck 53 is held by the two horizontal line portions of “Ko”, and the sealing mechanism 44 can be positioned in a space between the vertical lines. Thereby, the sealing mechanism 44 can be heat-sealed over the entire section including both ends of the opening of the inner bag B. Further, the sealing chuck 43 detects that the sealing chuck 43 holds the inner bag B securely, for example, in the vertical line portion of “U”, as in the holding jig 50 described above. More preferably, there is a holding confirmation sensor.

<Structure of Sealing Portion-8 (Sealing Mechanism 44)>
The sealing mechanism 44 is provided above the sealing chuck 43 and waits for the holding jig 50 to be retracted, and then toward the upper part of the position where the sealing chuck 43 of the inner bag B is held (in the right direction in the figure). Go forward. The tip of the sealing mechanism 44 is formed in a crab-like shape, and when it comes to the corresponding position of the inner bag B, it includes both ends of the opening of the inner bag B at a position corresponding to the U-shaped space of the sealing chuck 43. The heat seal is started by sandwiching the entire section from both sides. The sealing method is not particularly limited as long as it is a heat sealing method, but an impulse sealing method is preferable from the viewpoint of sealing strength.

<Configuration of Sealing Portion-9 (Second Jig Transfer Mechanism 41)>
Here, the second jig transfer mechanism 41 will be described. As shown in FIG. 7, the second jig transfer mechanism 41 can be moved left and right along the rail 411 installed on the left and right in the drawing and the rail 411 in the right side view, and can move up and down. And a jig transfer head 412 configured. The jig transfer head 412 is provided with a jig chuck and a coupler for detachably holding the holding jig 50, and the jig transfer head 412 operates the holding jig 50 via the coupler. Supply the air to make it happen.

<Configuration of Sealing Portion-10 (Second Jig Transfer Mechanism 41)>
The holding jig 50 opens the inner bag B, is retracted from the top opening P1 of the outer container P by the second jig transfer mechanism 41, and is then moved as it is to the return path 70 on the right side in the figure. 70 is transferred. And the holding jig 50 is returned to the inner bag supply part 20 one by one by operation of the filling and packaging machine 1. Although FIG. 1 shows an example in which seven holding jigs 50 are prepared, this does not cause a transfer blank for six outer containers P on the conveyance path 60. Plus one. When the operation is stopped, there are still six spaces on the return path 70, so the seventh holding jig 50 is provided with a lifter 71 provided above the return path 70 behind the sealed standby portion 304. ing.

<Effect of sealing part 40>
With the above-described series of configurations, even if the inner bag B is disposed in the outer container P and does not have a special spout or the like, the amount of air can be reduced and the outer container P can be covered, and a sealing failure or the like can occur Without it, it becomes possible to fill the powder or liquid almost full.

<Matters common to each part>
In the inner bag supply unit 20, the filling unit 30, and the sealing unit 40, the range of vertical movement of the holding jig 50, the filling nozzle 32, the deaeration mechanism 42, etc., and the height of the outer container P are the same as those of the outer container P. Depending on the container size (for example, as described above, 10L, 16L, etc.), it is stored in a non-volatile memory in a control mechanism such as a separate computer. When the filling and packaging machine 1 is operated, the container size and By setting the filling amount, an appropriate numerical value is automatically set. Furthermore, when an outer container P having a height that cannot be handled by the filling and packaging machine 1 is sometimes thrown in, it is detected by the control mechanism, and the filling and packaging machine is informed that the outer container P has been erroneously put. The operation of 1 is not started or stopped.

<Description of filling packaging method>
(Operation of the embodiment)
Next, as an operation of the present embodiment, a powder or liquid filling and packaging method using the filling and packaging machine 1 having the above-described configuration will be described.

<Overall configuration of filling and packaging method>
The filling and packaging method according to the present embodiment is roughly divided into an outer container supply step S10 for supplying the outer container P, an inner bag supply step S20 for supplying the inner bag B to the inside of the outer container P, and the inner bag B. Filling step S30 that fills the inside of the granular material or liquid, and sealing step S40 that heats the inner bag B by removing the air above the granular material or liquid filled in the inner bag B are provided. ing. Hereinafter, each step will be described in detail.

<Outer container supply step S10>
First, the outer container supply step S10 will be described with reference to FIGS. The outer container P is placed on the outer container stocker unit 11 of the outer container supply unit 10 in a stacked state (step S11). Outer containers P are separated from the lowermost stage one by one from the lowermost stage in the stage separation part 112 adjacent to the payout part 12 in the outer container stocker part 11, and the lowermost stage outer container is cut out. P is supplied to the dispensing unit 12 by the conveyor 111 (step S12). When the outer container P is placed on the dispensing unit 12 of the outer container supply unit 10 in a state of facing the downstream conveyance direction, the inner bag supply unit 20 has a pair of top surface openings P1 of the outer container P. The outer container P may be rotated 45 degrees between the outer container supply unit 10 and the inner bag supply unit 20 so that one of the angular directions is substantially parallel to the transport direction (step S13).

<Inner bag supply step S20-1>
Next, the inner bag supply step S20 will be described with reference to FIG. At the time before the work is started, the holding jig 50 is placed on the return path 70 behind the inner bag supply unit 20 (the right side in the figure), and the first jig transfer mechanism. 21 of the jig transfer head 212 is located directly above the holding jig 50 placed on the return path 70 (step S21). In this state, when the outer container P is conveyed to the inner bag supply unit 20 by the conveyance path 60, the supply of the inner bag B to the inside of the outer container P is started by the following procedure.

<Inner bag supply step S20-2>
In the return path 70 behind the inner bag supply unit 20, the jig transfer head 212 descends, closes the jig chuck, fixes the holding jig 50, and then rises. At this time, the jig transfer head 212 connects the coupler with the holding jig 50 to open the air supply path. Then, air is supplied from the jig transfer head 212 to the holding jig 50 to open the bag chuck 53 of the holding jig 50 and the inner bag guide of the bag guide 54. In combination with these operations, the suction pad 231 of the inner bag cutting mechanism 23 descends toward the bundle of inner bags B continuously placed on the inner bag stocker unit 22, and the suction pad 231 is evacuated. Thus, the uppermost inner bag B is adsorbed (step S22).

<Inner bag supply step S20-3>
When the vacuum value of the suction pad 231 reaches a predetermined value, the suction pad 231 turns 90 degrees upward about the fulcrum with the inner bag cutting mechanism 23 toward the back side of the apparatus (right side in the figure), or a rotating chuck Pass the inner bag B to 232. When the rotary chuck 232 receives the inner bag B, the suction pad 231 does not rotate, and the rotary chuck 232 moves 90 degrees upward about the fulcrum with the inner bag cutting mechanism 23 toward the back side of the apparatus (right side in the figure). Make a turn. At this time, neutralization of the inner bag B is started by the ionizer 24. In combination with these operations, the jig transfer head 212 has moved forward from the return path 70 side on the rear side of the apparatus (right side in the figure) toward the front of the apparatus (left side in the figure) while holding the holding jig 50. When the container P passes over the transport path 60 through which the container P is transported, the container P descends to a position corresponding to the suction pad 231. When the holding jig 50 comes to a position where the inner bag B sucked by the suction pad 231 comes into contact with the surface of the bag chuck 53 of the holding jig 50, the bag chuck 53 is closed and the inner bag B is held and sucked. The vacuum of the pad 231 is broken to release the suction (step S23).

<Inner bag supply step S20-4>
The jig transfer head 212 retracts once with the position where the center of the inner bag B and the center of the outer container P coincide with each other while the holding jig 50 holds the inner bag B. When the retreat is completed, the charge removal by the ionizer 24 is completed. And air is sprayed by the 1st air blow 25 with respect to the inner bag B which is in the state which covers the top | upper surface opening part P1 of the outer container P, and the bottom part of the inner bag B is dropped inside the outer container P ( Step S24).

<Inner bag supply step S20-5>
The jig transfer head 212 moves forward to a position where the holding jig 50 is directly above the back side (right side in the figure) of the top surface opening P1 of the outer container P (step S25).

<Inner bag supply step S20-6>
The jig transfer head 212 descends and mounts (transfers) the holding jig 50 on the two sides on the back side of the top opening P1 of the outer container P. At this time, air is sprayed between the holding jig 50 and the top surface opening P1 of the outer container P by the second air blow 26 provided under the return path 70, and the holding jig 50 and the outer container P are The inner bag B is prevented from being caught between the top opening P1. At the same time, the bag guide 54 is closed. When the bag guide 54 is closed, the coupler is disconnected from the jig transfer head 212 and the holding jig 50. Then, the jig chuck is released to release the holding jig 50 from the jig transfer head 212 (step S26).

<Inner bag supply step S20-7>
The jig transfer head 212 moves up and retracts toward the return path 70 after releasing the holding jig 50. The retreat position is a range that does not interfere with the next holding jig 50 that is next conveyed on the return path 70 (step S27).

<Inner bag supply step S20-8>
When the next holding jig 50 arrives at a position corresponding to the inner bag supply unit 20 on the return path 70, the jig transfer head 212 is directly above the next holding jig 50 that has arrived on the return path 70. Move (step S28). When the movement is completed, the state returns to step S21. The outer container P is transported to the next filling step S30.

<Filling step S30-1>
Next, the filling step S30 will be described with reference to FIG. At the time before the work is started, the filling nozzle 32 and the jig operating mechanism 31 are on standby so as not to interfere with the outer container P and the holding jig 50 (step S31). In this state, when the outer container P is transported by the transport path 60 in a state where the holding jig 50 is mounted on the two sides on the back side of the top surface opening portion P1, to the filling unit 30, according to the following procedure. Filling of the powder or liquid into the inner bag B is started.

<Filling step S30-2>
When the outer container P is transported to a fixed position by the outer container transport chuck 61, the jig operating mechanism 31 is lowered, and the bag opener 313 is lowered to just above the opening of the inner bag B (step S32). By providing such a stop time, shaking when the outer container P and the holding jig 50 are transported by the outer container transport chuck 61 is suppressed.

<Filling step S30-3>
Next, the outer container transfer chuck 61 is released one side at a time to perform tare measurement (step S33). By releasing one side at a time, it is possible to reduce the shaking generated by removing the outer container conveyance chuck 61.

<Filling step S30-4>
When the tare measurement is completed, the outer container P is fixed again by the outer container conveyance chuck 61, the jig operation mechanism 31 is lowered, and the bag opener 313 reaches the opening of the inner bag B. The arm 314 is pulled toward the proximal end, and the suction pad 315 of the bag opener 313 is pulled toward the jig operating mechanism 31. After the suction pad 315 sucks the opening of the inner bag B, the arm 314 is returned to its original position. Returning the suction pad 315 to the advanced position widens the opening of the inner bag B. At that time, the bag chuck 53 of the holding jig 50 is narrowed (step S34).

<Filling step S30-5>
The dripping receptacle 33 that has covered the tip of the filling nozzle 32 until then is removed. Then, the filling nozzle 32 descends toward the opening of the inner bag B spread by the bag opener 313. At this time, the tip of the filling nozzle 32 is stopped near the top surface opening P1 of the outer container P until it is inserted into the outer container P, and small filling is started, and the inner bag B is inserted into the outer container P. Drop into the bag and make sure the bag opens. Thereafter, the tip of the filling nozzle 32 is inserted to the vicinity of the bottom of the outer container P (at a height within 10 cm from the bottom), and at the same time, the holding jig 50 is raised by the jig operating mechanism 31 and the inner bag B is small-filled. The lower end of the inner bag B moves away from the bottom surface of the outer container P and starts large filling (step S35).

<Filling step S30-6>
In this state, filling proceeds by the filling nozzle 32. During filling, the jig operating mechanism 31 is lowered so that the inner bag B does not wrinkle, sag, tear or the like. Moreover, the filling nozzle 32 moves up in order to keep the distance between its tip and the surface of the powder or liquid to be filled constant. Filling is performed in two stages, large filling (coarse filling) and small filling (adjustment filling). During the large filling, the outer container transport chuck 61 is released and the holding jig 50 is mounted on the outer container P. Then, the jig chuck of the jig operating mechanism 31 is opened, and the small amount is filled until the target filling amount is reached while measuring the filling amount in consideration of the tare measurement result by the measuring device 34 (step S36). ).

<Filling step S30-7>
When the filling is completed, the filling nozzle 32 rises to the standby position in step S31, and the drooping receptacle 33 returns to a position covering the tip of the filling nozzle 32. On the other hand, the jig operating mechanism 31 closes the jig chuck and is reconnected to the holding jig 50, releases the suction of the suction pad 315 of the bag opener 313, and widens the bag chuck 53 of the holding jig 50. Close the opening of the inner bag B. Thereafter, the jig chuck of the jig operation mechanism 31 is released, and the holding jig 50 is separated from the jig operation mechanism 31 (step S37).

<Filling step S30-8>
The jig operation mechanism 31 is raised to the standby position. When the increase is completed, the state of step S31 is established (step S38). The outer container P is transported to the next sealing step S40.

<Sealing step S40-1>
Next, the sealing step S40 will be described with reference to FIG. At the time before the work is started, the plate portion 421 of the deaeration mechanism 42 and the jig transfer head 412 of the second jig transfer mechanism 41 are moved upward so as not to interfere with the outer container P and the holding jig 50. Waiting at. Further, the sealing chuck 43 and the sealing mechanism 44 for sealing the inner bag B are waiting in front of the apparatus (left side in the drawing) (step S41). In this state, when the outer container P is conveyed by the conveyance path 60 in a state where the holding jig 50 is placed on the two sides on the back side of the top surface opening P1, the following procedure is performed. Then, deaeration and sealing of the inner bag B are started. The holding jig 50 only needs to be removed from the outer container P in the steps after the sealing step including the sealing step, and the second jig transfer mechanism 41 is not necessarily provided in the sealing portion 40. If the sealing part 40 is provided, the filling and packaging machine 1 can have a compact design, and therefore, here, description will be made assuming that the sealing part 40 is provided.

<Sealing step S40-2>
When the outer container P is transported to a fixed position, the plate portion 421 descends to an arbitrary height necessary for removing air above the powder or liquid in the inner bag B. The sealing chuck 43 moves forward toward the outer container P and rises around the bag chuck 53 of the holding jig 50 to hold the inner bag B. When the inner bag B is held by the sealing chuck 43, the bag chuck 53 and the bag guide 54 of the holding jig 50 are opened (step S42).

<Sealing step S40-3>
When the plate portion 421 returns to its original height, the seal chuck 43 is on the front side of the device (left side in the figure) when the lower end of the plate portion 421 comes to a position higher than the upper end of the inner bag B. Next, it moves within a range that does not intersect the bag chuck 53 of the holding jig 50 (step S43).

<Sealing step S40-4>
The holding jig 50 is moved backward by the jig transfer head 412 to avoid the intersection of the sealing chuck 43 and the holding jig 50 on the plane of the bag guide 54 (step S44).

<Sealing step S40-5>
The holding jig 50 is raised by the jig transfer head 412. As a result, when the lower surface of the holding jig 50 exceeds the height of the sealing mechanism 44, the sealing mechanism 44 advances to a position corresponding to the sealing chuck 43. The bag chuck 53 and the bag guide 54 of the holding jig 50 are closed, and the coupler is removed from the jig transfer head 412 to disconnect the air (step S45).

<Sealing step S40-6>
In this state, the sealing mechanism 44 that has moved forward heat seals with the opening of the inner bag B interposed therebetween. The sealing conditions can be, for example, heating for 1.9 seconds, cooling for 2.7 seconds, and applied pressure of 2 kg / cm ² , but these conditions can be adjusted. During this time, the jig transfer head 412 transfers the holding jig 50 onto the return path 70 and then returns to above the outer container P (step S46).

<Sealing step S40-7>
After cooling, the sealing chuck 43 opens the inner bag B and returns to the original position. At the same time, the sealing mechanism 44 that has finished cooling also returns to its original position. When both positions return, the state of step S41 is established (step S47). The outer container P is paid out from the filling and packaging machine 1.
