It will be manufactured as a package.
Japanese Patent No. 2759586 (see pages 2 to 7, see FIG. 1)

  However, in general, the contents are not composed of only one type of granule, but are often composed of a plurality of granules mixed therein. For example, when the content is a medicine, A granules for relieving the affected area and B granules for protecting the stomach, for example, are included, and the amount contained is generally determined as the filling ratio.

  In the conventional metering and filling apparatus, the contents stored in the hopper are collectively stored in the hopper with the filling ratio already determined. And since it is supplied in the state which A granule and B granule were mixed when it is supplied to a measurement part from a hopper, the content finally manufactured as a packaged product is A granule and B granule. Are not necessarily mixed at a predetermined filling ratio. Depending on the contents, this filling ratio has to be mixed almost accurately, which necessitates weighing two granules separately and filling them into a packaging bag.

  Further, in the measuring section of the conventional metering and filling apparatus, the rotating rotor is fitted in a sliding contact state over the entire periphery between the outer peripheral surface and the housing that covers the outer peripheral surface of the rotor. A part of the contents that have been moved from the storage part of the rotor to the measurement recess enters the gap between the outer peripheral surface of the rotor and the housing and is sent to the back. Some of the contents inserted into the gap have a large contact area between the rotor and the housing, and are in a state of being kneaded by the rotating rotor, which may cause the rotor to move poorly or in some cases the housing Will cause damage.

The present invention solves the above-mentioned problems, and the contents produced by mixing two or more types of granules are measured and filled in a packaging bag for each granule without reducing the movement of the rotor. An object of the present invention is to provide a weighing and filling apparatus in a packaging machine that can be used. For this purpose, the weighing and filling apparatus in the packaging machine of the present invention is configured as follows. That is, in the invention described in claim 1, in order to fill a packaging bag formed in a bag shape with a content composed of at least two types of granules, a hopper for storing each granule, and each granule A rotor that can be housed and rotated in a housing, a weighing recess for weighing the contents supplied from the hopper for each granule, and a shutter member that can open the weighing recess from below, and each weighing A filling unit that collects the granules weighed from a part and fills them in a lump, and a weighing and filling device in a packaging machine,

The filling unit is provided with a filling tube that collects each granule flowing out from the measuring unit and fills the packaging bag as one content.

According to a second aspect of the present invention, the partition plate is inserted into the groove and is fixed to the rotor by being engaged with an engagement recess formed in the partition plate by a stopper member. It is characterized by.

In the invention according to claim 3, in order to fill a bag formed in a bag shape with a content composed of at least two types of granules, a hopper for storing each granule, and a container for each granule are stored. A weighing unit comprising a rotor rotatable inside the housing and a weighing recess for weighing the contents supplied from the hopper for each granule and a shutter member capable of opening the weighing recess from below; and from each weighing unit A weighing and filling device in a packaging machine comprising: a filling unit for collecting and filling the weighed granules,
The rotor is formed in a cylindrical shape having an opening at the top and at least two chambers that are partitioned by a partition plate and separately store the granules. An inflow hole for inflow is formed and a granule supply pipe for supplying and guiding the granules into the chambers is disposed through the opening, and the inner peripheral surface of the rotor is arranged along the circumferential direction along the circumferential direction. A groove into which the partition plate is inserted is formed, and the partition plate is inserted into the groove and is fixed to the rotor by being engaged with an engagement recess formed in the partition plate by a stopper member. The filling portion is provided with a filling tube that collects each granule flowing out from the measuring portion and fills the packaging bag as one content .

According to a fourth aspect of the present invention, the shutter member is disposed so as to be movable between a position where a plurality of granules stored in the measuring recess are simultaneously opened and a position where one kind of granule is opened. And

  According to the first aspect of the present invention, the granules stored in each hopper are guided to the granule supply pipe inserted into each chamber from the opening of the rotor and supplied to each chamber of the rotor. When each granule is supplied into each chamber, the granule supplied to each chamber in the rotor by rotating the rotor is moved to the respective measuring recess through the inlet hole of the rotor and weighed to a certain amount. The When each granule is weighed to a predetermined amount, the shutter member moves to open the metering recess, and each granule is filled into the packaging bag through the filling tube.

  Therefore, each granule that constitutes the contents is weighed to a predetermined amount according to the contents, so even if the contents are composed of a plurality of granules, the filling ratio of each granule is accurately ensured. can do.

In addition , since the partition plate is inserted into the groove on the inner peripheral surface and partitioned for each chamber, the rotor is formed in a cylindrical shape, so that a wide hollow portion is formed inside, and the granules connected to the hopper The supply pipe can be inserted deep into the lower part of each room. As a result, the granule can be stored in the vicinity of the inflow hole as much as possible, and can be quickly moved from the inflow hole to the measurement recess by the rotation of the rotor.

After that, the stopper member is fastened with bolts from the outside of both end wall surfaces of the rotor. Moreover, it is desirable to insert the stopper member on both the left and right sides with respect to the central axis of the partition plate. As a result, the bolts for fixing the partition plate can be eliminated in each chamber of the rotor, and the space can be increased by that amount, and foreign materials can be prevented from entering the chamber due to, for example, dropping of bolts or the like. can do.

According to invention of Claim 4 , each granule can be measured independently besides normal measurement filling operation | work. That is, for example, if a first position for forming a filling hole for passing all the granules through the shutter member and a second position for forming a filling hole for passing one kind of granule are provided, each granule in normal operation is weighed. In the case of filling, the shutter member is moved to the position opposite to the measurement recess from the first position, and only one of the granules is measured. The shutter member is moved from the second position to a position facing the measurement recess.

The position of the second row, the position of the second row, and the position of the third row are adjusted as necessary. Adjustment for moving the position of the first row, the position of the second row, and the position of the third row is performed by moving the fulcrum portion 221 connected to the link mechanism of the connecting plate 22 along the moving direction of the shutter member 20. Done. The drive mechanism is not particularly limited, but the drive source may be driven by rotation of a cam via a link mechanism, or the link mechanism may be driven using a servo motor. When driven by a servo motor, it automatically moves to the position of the first row where each granule is weighed during normal continuous driving and the position of the second row or third row where only one single granule is weighed. Can be adjusted.

  As shown in FIG. 3, the filling unit 25 includes a filling tube 26 and a moving mechanism 27 that moves the filling tube 26 toward and away from the measuring recess 14. The filling tube 26 has a hopper portion 261 and a guide portion 262 and is formed in a vertically long shape. The filling tube 26 fills the contents into the two packaged articles 100, so that the filling hole 21 of the shutter device 20 is formed in the measuring recess. Opposite the position where 154 is opened, two places will be arranged side by side.

  The moving mechanism 27 is driven by a cam 271 (or a servo motor) and, when receiving the contents, moves the filling tube 26 upward to approach the measuring recess 14 and fills the packaging bag F with the contents. In this case, the filling tube 26 is moved downward to be separated from the measuring recess 14.

  Next, the operation of the apparatus 10 configured as described above will be described.

  As shown in FIGS. 3 to 4, each kind of granule mixed into one content is stored in each hopper 11, and each granule is supplied into each chamber 151 of the rotor 15 through the granule supply pipe 133. ing. For example, the main purpose granule mixed in the packaged products 100A and 100B is stored in the hopper 11B, and the sub target granule is stored in the hopper 11A and the hopper 11C. The granules stored in the hopper 11A and the hopper 11B constitute one content to be manufactured as a packaged product 100A, and the granules stored in the hopper 11B and the hopper 11C constitute one content and packaged. Manufactured as 100B.

  In the state of FIG. 10A, the granules supplied to the respective chambers 151 are moved to the measuring recesses 14 to measure the volume of the granules, and the rotor 15 rotates the inlet hole 154 from the bottom dead center position to the clockwise position. In the state of being rotated in the direction, the inflow hole 154 and the measurement recess 14 are not aligned. The shutter member 20 uses the filling holes 21D arranged in the first row, and in this state, the shutter member 20 is moved to a position where the measuring recess 14 is closed. Further, the adjusting member 141 is adjusted and moved, and the capacity of the measuring recess 14 is set to a predetermined capacity.

  The packaging film F <b> 1 is sent out from the supply reel 3 in FIG. 1, and is formed as a packaging bag F in the bag making unit 5. On the other hand, as shown in FIG. 10B, when the rotor 15 is rotated counterclockwise, each inflow hole 154 of the rotor 15 communicates with the measuring recess 14 and is supplied into each chamber 151 of the rotor 15. Each granule that has been moved is moved to the metering recess 14.

  As shown in FIG. 11A, when the rotor 15 rotates in the clockwise direction and the inflow hole 154 exceeds the measuring recess 14, the scraped portion 155 formed at the peripheral edge around the inflow hole 154 becomes the measuring recess 14. The upper surface is ground and the granules are weighed.

  Then, as shown in FIG. 11B, the shutter member 20 is moved to a position where the filling hole 21 </ b> D communicates with the measurement recess 14. As a result, the measuring recess 14 is opened, and the granules fall toward the filling tube 26 and are filled in the packaging bag F.

  Each granule accommodated in the measurement concave portion 14A and the measurement concave portion 14B1 is filled into the packaging bag F through the filling tube 26A, longitudinally sealed and laterally sealed by the bag making portion 5, and cut by the cutter device 7, and then packaged. Manufactured as a product 100A. Each granule stored in the weighing recess 14B2 and the weighing recess 14C is filled into the packaging bag F through the filling tube 26B, vertically sealed, laterally sealed, cut by the cutter device 7, and cut into the package 100A together with the package 100A. Manufactured.

  Note that the timing when the granules flow out from the measuring recess 14 is performed when the filling tube 26 comes closest to the measuring recess 14.

  As a result, one cycle is completed, and the state returns to the state shown in FIG.

  In addition, in this apparatus 10, it can be checked whether each granule is measured correctly. For example, when the weight of only the main target granules stored in the hopper 11B is confirmed, the filling holes 21E1, 21E2 in the second row are used instead of the filling holes 21D1, 21D2. That is, the shutter member 20 is moved to move the filling holes 21E1 and 21E2 to positions where they can face the measurement recesses 14B1 and 14B2.

  Since the lower surfaces of the measurement recess 14A and the measurement recess 14C are not opened, the granules stored in the measurement recesses 14B1 and 14B2 can be taken out independently by performing the same operation as the above-described one cycle. .

  According to the apparatus 10 configured and operated as described above, when filling the packaging bag F with the contents mixed with at least two kinds of granules, the granules constituting the contents are Since each is measured to a predetermined amount according to the contents, the filling ratio of each granule can be ensured accurately.

  That is, the rotor 15 having the partition plate 16 inserted into the engagement groove 152a on the inner peripheral surface and partitioned for each chamber 151 forms a wide hollow portion inside, and the granule supply pipe 133 connected to the hopper 11 is formed. Can be inserted deep into the bottom of each chamber 151. As a result, a minimum amount of granules can be stored in the vicinity of the inflow hole 154 of the rotor 15, so that the rotation of the rotor 15 can quickly move the inflow hole 154 to the measuring recess 14, and each granule is almost Configured as one content weighed at an accurate fill ratio.

  Further, when the granule stored in the measuring recess 14 is scraped by the scraping portion 155 of the rotor 15, the scraping portion 155 of the rotor 15 is in sliding contact so as to reduce the contact area. Granules that have entered the gap between them are less likely to be kneaded due to the rotation of the rotor 15. Accordingly, the measurement can be performed without reducing the movement of the rotor 15 and without damaging the housing portion 131.

  Further, when the partition plate 16 is assembled in the rotor 15, it is not necessary to fix the partition plate 16 to each chamber of the rotor 15 with bolts, so that the rotor 15 can be formed compactly and the rotor It is possible to prevent foreign matters from being mixed into the 15 chambers 151 due to the drop of bolts or the like.

  In addition, the shutter member 20 that can open the measuring recess 14 has a first position where a filling hole 21 through which all the granules pass is formed, and a second or third where a filling hole 21 through which one kind of granule passes is formed. Therefore, in addition to the usual metering and filling operation, each granule can be weighed independently.

  In addition, the apparatus of this invention is not limited to said form. For example, the configuration for weighing each granule may be a square disk weighing type having a box-shaped case that reciprocates instead of a cylindrical weighing type whose rotor shape is rotatable. Can be weighed for each granule by mounting it according to the shape of the case.

  In the above form, the package is formed with two pieces, but even if there are three or more pieces, the rotor chamber is formed in the same manner as the above form according to the package. can do. Furthermore, even if there are two or more types of granules, the number of rotor chambers and the number of filling tubes can be configured to match each granule.
