Description

  The present invention belongs to the technical field of an automatic packaging machine for automatically filling and packaging powder raw materials (contents) using a packaging film (packaging material). Specifically, the packaging film has a substantially cylindrical cross section. The present invention relates to a raw material supply device in a vertical multi-row automatic packaging machine that forms a stick packaging bag by forming into a shape.

  2. Description of the Related Art Conventionally, there is a vertical multi-row automatic packaging machine configured so that a plurality of stick-type packaging bags can be continuously sealed at a time. Each of the packaging films cut into a plurality of pieces is wound around each former pipe configured in a multi-row form, formed into a cylindrical shape, and then longitudinally sealed against the seam of the packaging film by a longitudinal heat sealer. To form a cylindrical shape, and then a horizontal seal is applied to a specified position of the cylindrical packaging film by a horizontal heat sealer.

  The vertical multi-row automatic wrapping machine fills the raw material (contents) with a filling pipe into the finished bag-shaped packaging film, and then seals the raw material inlet by sealing it horizontally. It is separated by using a cutter device near the center of the sealed horizontal seal portion, and finally the stick-shaped packaging bags in individual packaging form are multi-row and continuously sealed. . An example of such a vertical multi-row automatic packaging machine is disclosed in Patent Document 1.

FIG. 7 is a schematic side view of a raw material supply apparatus in a conventional vertical multi-row automatic packaging machine. As shown in FIG. 7, the structure of the conventional raw material supply apparatus is as follows.
(1) The powder raw material is contained in the hopper 102, and a gap is opened between the lower outlet of the hopper 102 and the slide supply board 107. The powder raw material contained in the hopper 102 is gradually sent out to the slide supply board 107 from this gap.
(2) A front scraper 104 and a rear scraper 105 are provided above the slide supply board 107 with the hopper 102 interposed therebetween.
(3) The slide supply board 107 has an opening for adjusting the measurement mass 118, and a shutter 108 for closing the lower part of the measurement mass 118 is provided below the slide supply board 107.
(4) A connection chute 109 and a filling pipe 110 are installed under the shutter 108 of the slide supply board 107.

The operation of such a conventional raw material supply apparatus is as follows.
(1) A series of operations from weighing the powder raw material in the hopper 102 to putting the measured powder raw material into the filling pipe 110 is realized by moving only the slide supply board 107 and the shutter 108 back and forth. The other components are fixed.
(2) First, the slide supply board 107 is driven so as to be located on the rightmost side when viewed from the side, and the weighing mass 118 is located immediately below the lower outlet of the hopper 102. Further, the lower side of the measuring mass 118 is closed by the shutter 108.
(3) As a result, the powder raw material is piled up into the weighing mass 118, and from this state, the slide supply board 107 and the shutter 108 are driven to the left as viewed from the side.
(4) During this driving, the weighing mass 118 of the slide supply board 107 is cut by the front scraper 104. That is, by the mass cutting operation by the previous scraper 104, the pile portion of the powder raw material contained in the measuring mass 118 is pushed away and the volume value of the measuring mass 118 is measured.
(5) Further, the movement of the shutter 108 is set to be smaller than the movement of the slide supply board 107, and the slide supply board 107 is stopped while moving in the left direction as viewed from the side. For this reason, when the slide supply board 107 is located on the leftmost side when viewed from the side, the shutter 108 that has closed the lower side of the weighing mass 118 is opened.
(6) The connecting chute 109 and the filling pipe 110 are located immediately below the measuring mass 118 when the slide supply board 107 comes to the leftmost side when viewed from the side, and the weighing is measured to a correct value. The powder raw material in the mass 118 falls into the connection chute 109 and is filled into the packaging bag via the filling pipe 110.
Japanese Patent Laid-Open No. 9-272511

  When the powder raw material is charged into the individual packaging bag using the raw material supply apparatus in such a conventional vertical multi-row automatic packaging machine, the filling situation greatly varies depending on the properties of the powder raw material to be charged. In particular, when the input raw material is a granular dry powder raw material, the raw materials rub against each other to generate a large amount of static electricity, and this static electricity causes the powder raw material to pass through the gap between the lower outlet of the hopper 102 and the slide supply board 107. When it is sent to the slide supply board 107, it shows a behavior of repelling and jumping.

  For this reason, the powder raw material once entered into the measuring mass jumps out of the measuring mass, and the mass-measured value decreases. Therefore, the packaging bag filled with such a powder raw material has a problem that the amount of contents is insufficient.
