  FIG. 4 is an external side view of the filling chute 7 according to the present invention as viewed from the direction of the mounting screw member 43. FIG. 5 is a side view of the filling chute 7 according to the present invention as viewed from the direction of the mounting screw member 43 in a longitudinal sectional state. As shown in FIG. 4, the filling chute 7 includes a funnel-shaped upper chute 21 and a substantially oval cylindrical lower chute 22, and a mounting screw member 43 of the crushing chute 40 is fitted into the upper chute 21. An incision groove 44 is provided for inserting and fixing. As a result, the filling chute 7 and the grinding chute 40 can be easily attached and detached. 4 includes a crushing chute 40 and a crushing plate member 42 attached with a gap 45 provided therebetween, which are represented by dotted lines.

  On the other hand, as shown in FIG. 5, the filling chute 7 is composed of a funnel-shaped upper chute 21 and a substantially oval cylindrical lower chute 22. The positional relationship between the existing crushing chute 40 and the crushing plate member 42 is easy to understand. Then, a crushing bar member 41 expressed by a dotted line is spanned inside the inlet of the crushing chute 40. In the case of the crushing bar member 41 expressed in FIG. 5, a round bar shape is adopted. .

  4 to 6, the arm 20 shown in FIG. 3 is omitted for the sake of clarity, and only the main body of the filling chute 7 is shown and described.

  FIG. 6 is a side view of the filling chute 7 according to the present invention as viewed from the direction opposite to the surface on which the crushing bar member 41 is stretched in the longitudinal cross-sectional state. As shown in FIG. 6, the filling chute 7 is composed of a funnel-shaped upper chute 21 and a substantially oval cylindrical lower chute 22. In the state where 45 is held, it is fixed by the mounting screw member 43. Further, a grinding rod member 41 represented by a dotted line is spanned inside the inlet of the grinding chute 40, and a grinding plate member 42 extends at the outlet of the grinding chute 40 as shown in FIG. . The crushing plate member 42 has a partially curved shape along the funnel-shaped wall surface of the filling chute 7.

  FIG. 7 is a top view of members taken out from the grinding chute 40 of the present invention. FIG. 8 is a side view of the members associated with the grinding chute 40 of the present invention taken out and viewed from the direction of the mounting screw member 43. FIG. 9 is a side view of a member related to the crushing chute 40 of the present invention taken out from a direction facing the surface on which the crushing bar member 41 is stretched. As shown in FIGS. 7 to 9, a crushing bar member 41 is stretched inside the inlet of the crushing chute 40, and a crushing plate member 42 extends at the outlet of the crushing chute 40. Further, in order to fix the grinding chute 40 to the upper chute 21 of the filling chute 7, an attachment screw member 43 is provided on the side surface of the grinding chute 40.

  Although the crushing bar member 41 shown in FIGS. 7 to 9 has a round bar shape, the invention is not limited to this, and any cross-sectional shape can be adopted. For example, a case where a crushed rod member having a triangular cross-section is attached with one corner facing up, or a case where a crushed rod member having a long cross-sectional shape is mounted on a short side is conceivable. Moreover, although the crushing chute 40 shown in FIG. 7 thru | or FIG. 9 demonstrated in the example in which the one crushing bar member 41 was spanned inside the insertion port, it is not limited to this, Arbitrary crushing bar members Can be handed over. For example, a case where two crushed rod members are crossed at right angles and a case where a plurality of crushed rod members are arranged in parallel can be considered.

  Thus, the cross-sectional shape and the mounting arrangement of the pulverizing rod member can be arbitrarily selected as a means for pulverizing as finely as possible in accordance with the properties of the powder content.

  FIG. 10 shows the powder chute 7 being charged into the filling chute 7 based on the side face of the filling chute 7 according to the present invention as viewed from the direction opposite to the surface across which the grinding bar member 41 is stretched. It is the operation | movement schematic explaining the process grind | pulverized. As shown in FIG. 10, the powder content 50 weighed by the content supply device is dropped at the inlet of the filling chute 7 as shown by a locus a <b> 1. Thereafter, the powder content 51 divided into two parts by the crushing bar member 41 of the crushing chute 40 falls as shown by a locus a2, collides with the funnel-shaped wall of the crushing chute 40, and bounces as a locus a3. . Then, the powder content rolls down the funnel-shaped wall surface of the crushing chute 40 and the lump state is further broken on the crushing plate member 42. As a result, the powder content 52 pulverized to be smaller than the size of the funnel-shaped outlet of the filling chute 7 can easily pass through the filling chute 7, and clogs the funnel-shaped outlet of the filling chute 7, so-called clogging problem. Can be eliminated.

  On the other hand, the finely pulverized powder content 52 is introduced into the bag portion 12 via the filling chute 7. At this time, the air in the bag portion 12 rises up the filling chute 7 for an outlet. As a result, it collides with the falling powder content and causes a phenomenon of powder rising. For this reason, a gap 45 is provided between the filling chute 7 and the crushing chute 40 in order to quickly exhaust the air in the rising bag portion 12, and the rising exhaust is the route indicated by the trajectory b1 and the trajectory b3. Passes through the gap 45 and is discharged (exhaust) along the routes indicated by the trajectory b2 and the trajectory b4. Thus, by providing the gap 45 between the filling chute 7 and the crushing chute 40, it becomes possible to replace the falling powder content 52 and the air in the bag portion 12 without colliding with each other, thereby suppressing the phenomenon of powder rising. It becomes possible.

  Although the pulverization plate member 42 of the pulverization chute 40 has been described as adopting a plate shape, the pulverization plate member 42 is not limited to this, and any pulverization plate member 42 may be used as long as it has an action of pulverizing a lump of powder contents. For example, the same effect can be expected even when a comb-shaped or net-shaped member is used.

  FIG. 11 is a top view of another filling chute 77 and arm 120 that are inserted into the folded packaging film in the rotary automatic packaging machine of the present invention. As shown in FIG. 11, the filling chute 77 has a double structure in which the upper surface side is closed, and the funnel-shaped main body of the upper chute 121 that is the outer filling chute can be seen.

  Note that the double structure of the filling chute 77 has a fitting shape, and in a regular cleaning operation, the mounting screw member 143 is loosened so that it can be disassembled into an external filling chute and an internal filling chute.

  Further, in the top view shown in FIG. 11, the concept of the cooling mechanism is illustrated, and cooling air before use is sent into the inside of the filling chute 77 from an inlet 148 disposed below the filling chute 77 in the figure. The used cooling air is discharged from the inside of the filling chute 77 through an outlet 149 disposed above the filling chute 77 in the figure. That is, the cooling air feeding operation described above is performed by the charging chute 77 rotating on the turntable 4 from the jet cylinder in which the compressed and cooled clean air is fixed to the center portion of the turntable 4. It is discharged toward the inlet 148 and sent.

  FIG. 12 is an external side view of another filling chute 77 of the present invention viewed from the inside of the turntable. FIG. 13 is a side view of another filling chute 77 according to the present invention as viewed from the outside of the turntable in a longitudinal sectional state. As shown in FIG. 12, the filling chute 77 is composed of a funnel-shaped upper chute 121 and a substantially oval cylindrical lower chute 122, and the upper chute 121 has an attachment screw for fixing the internal filling chute. There is a member 143.

  An inlet 148 through which cooling air is sent is disposed between the upper chute 121 and the lower chute 122. In addition, inside the external side view of the external filling chute constituted by the upper chute 121 and the lower chute 122 in FIG. 12, the internal filling chute fitted with a gap is represented by a dotted line.

  On the other hand, as shown in FIG. 13, the filling chute 77 is constituted by an external filling chute composed of an upper chute 121 and a lower chute 122 and an internal filling chute 146 in which the size of the external filling chute is reduced. Because of the longitudinal cross-sectional state, the positional relationship of the internal filling chute 146 fitted into the external filling chute is easy to understand. The inner filling chute 146 is fitted to the outer filling chute while holding the gap 145, and a mounting screw member 143 is provided to fix the inner filling chute 146 to the upper chute 121.

  A spacer member 147 is provided to fix the inner filling chute 146 to the lower chute 122, and cooling air is sent between the upper chute 121 and the lower chute 122 of the outer filling chute as in FIG. An inlet 148 is provided.

  In FIGS. 12 to 14, the arm 120 shown in FIG. 11 is omitted for the sake of clarity, and only the filling chute 77 main body is shown and described.

  FIG. 14 is a schematic operation diagram illustrating the flow of cooling air with another filling chute 77 of the present invention in a longitudinal cross-sectional state including an inlet 148 and an outlet 149 for cooling air. As shown in FIG. 14, cooling air before use is sent from the inlet 148 disposed in the lower chute 122 into the gap 145 from the ejection cylinder fixed to the center portion of the turntable 4 and disposed in the upper chute 121. The used cooling air is discharged from the outlet 149. The cooling air plays a role of cooling the internal filling chute 146 itself while passing through the gap 145. In particular, the constricted portion of the internal filling chute 146 in which the powder contents in the middle of dropping tend to melt and adhere. The cooling is intensive.

  In addition, a spacer member 147 is provided so that the cooling air sent into the gap 145 does not go below the filling chute 77, and flows from the inlet 148 toward the outlet 149.

  In the rotary automatic packaging machine of the present invention, there are a case where the cooling air discharged from the jet cylinder fixed to the center portion of the turntable 4 is continuously controlled and a case where the cooling air is controlled intermittently. In this intermittent discharge control case, the cooling air is controlled to be discharged only when the charging chute 77 rotating on the turntable 4 comes just before the fixed ejection cylinder. The consumption of cooling air can be suppressed. Naturally, the cooling capacity increases as the set temperature of the cooling air decreases, and at the same time increases as the amount of cooling air released increases.

  In this way, by lowering the temperature of the internal filling chute 146 itself with which the powder content in the middle of dropping falls, the dissolution of the oil component contained in the powder content is suppressed and the powder content adheres inside the filling chute. To prevent the situation. As a result, there is no obstacle to the melted powder content clogging the funnel-shaped outlet of the filling chute, and the powder content filling operation in the rotary automatic packaging machine can be maintained for a long time.

  As described above, the rotary automatic packaging machine according to the present invention has a structure that is easy to clean, and has a filling chute that is devised to solve the problem of clogging due to powder contents and the problem of powder rising. A rotary automatic packaging machine can be provided.
