Description

  The present invention relates to a solid filling method of filling a container with a predetermined amount of solid matter, and in particular, a first step of charging solid matter into a cylinder through an upper end opening of the cylinder, and the first step. After the first step, a second step of measuring the mass of the solid material put into the cylinder in the conveyance process, and after this second step, a part of the runway is retracted in the conveyance process. And a third step of opening the lower end opening of the cylindrical body and dropping and filling solid matter into a container located below the lower end opening.

  Conventionally, there is no particular prior art document in a solid filling process that fills a container with a predetermined amount of solids such as flake meat, apricot tofu, or peeled tangerine. However, for example, after filling a weighing container with an approximate amount of solids, weighing and adjusting to a predetermined amount, the weighing container is turned upside down so that the opening of the weighing container faces downward and is positioned below A method has been adopted in which a solid material is charged into a container.

  However, in the solid filling method as described above, the apparatus becomes complicated because the measuring container is inverted after weighing. Moreover, if the reversing operation speed is increased, the solids will fall from the container. Risk increases.

  The present invention has been made to solve the above-described problems.

  The invention according to claim 1 closes the lower end opening of the cylindrical body by contacting the lower end of a substantially cylindrical cylindrical body having an opening in the vertical direction on a runway having an upper portion formed of a horizontal plane.

By the lowering of 531, the pushing member 54 pushes the solid material b in the cylindrical body 8 into the container 9 and fills it.

  Next, a solid filling method using the solid filling apparatus A configured as described above will be described with reference to FIG. First, as shown in FIG. 5, the turntable 31 is rotated synchronously with the conveyor 2, and the solid material b is supplied onto the turntable 31 from the solid material supply nozzle 32.

  And the supplied solid substance b is thrown into the temporary container 7, and when the turntable 31 rotates to the arrow direction of the figure, the excess solid substance b which protruded from the temporary container 7 is removed by the scraping plate 37. The approximate amount is accommodated in the temporary container 7.

  Then, the temporary container 7 is conveyed to the primary filling part A1, and in the process of conveyance, the solid material b is introduced into the cylinder 8 through the upper end opening 81 of the cylinder 8 (first process). As shown in FIGS. 7A and 7B, when the partition plate 33 that is in contact with the lower side is retracted by the advance / retreat means 34, the solid matter b in the temporary container 7 is stored in the storage space 83 in the cylinder 8. It falls into the inside due to its own weight. At this time, if the pushing means 35 is operated and the pushing member 36 forcibly pushes the solid material b into the cylindrical body 8, the solid material b can be transferred more reliably.

  And after throwing the solid substance b into the cylinder 8 (1st process), when the cylinder 8 conveyed by the conveyor 2 reaches the measurement part A2, it was thrown into the cylinder 8 in the process of conveyance. This is for measuring the mass of the solid material b (second step). As shown in FIGS. 8 and 9, the mass of the solid material b is measured by the measuring instrument 4, and directly with the cylinder 8 and the solid material. The total mass of the object b is measured, but if the mass of the predetermined cylinder 8 is subtracted, the mass of the solid object b can be calculated.

  If the weight of the weighed solid material b is within the predetermined range, the process proceeds to the next process, but if it is outside the predetermined range, it is removed from the conveyor 2 or manually or automatically (not used). The solid material b is replenished into the cylindrical body 8 when the mass is smaller than the predetermined mass, and the solid mass b is reduced from the cylindrical body 8 when the mass is larger than the predetermined mass so as to be within a predetermined range. You may make it adjust.

  Then, after measuring the mass of the solid material b (second step), when the cylinder 8 conveyed by the conveyor 2 reaches the secondary filling part A3, a part of the runway 1 is retracted in the process of conveyance. The lower end opening 82 of the cylindrical body 8 is opened, and the solid material b is dropped and filled into the container 9 located below the lower end opening 82 (third step). Specifically, 11 (a) and 11 (b), the partition plate 51 in contact with the lower end of the cylindrical body 8 is retracted by the advancing / retreating means 54 and stored in the storage space 83 by opening the lower end opening 82. The solid material b that has been dropped falls by its own weight and is filled in the container 9. At this time, if the solid member b is forcibly pushed into the container 9 by the pushing member 54 by operating the pushing means 53, the solid substance b can be filled into the container 9 more reliably.

  And after filling the solid substance b into the container 9, this container 9 is conveyed by the main line B as shown in FIG. 1, and is taken over by the liquid injection process, the heat seal process, etc. which are not shown in figure.

  By the way, in the above-described embodiment, an example in which the four temporary containers 7, the cylinder 8, and the container 9 are operated as one unit has been shown. May be operated as a unit.

  Further, in the above-described embodiment, the example in which the pushing means 35 and 53 are provided is shown, but either one or both may be provided.
