Japanese Patent Publication No.51-32155

  The automatic packaging machine disclosed in Patent Document 1 has a high speed because the long film 1, the nozzles 107, 107. It is difficult to do and the productivity is bad. Other conventional powder packing and packaging devices can generally produce only 80 bags per minute.

  Then, this invention makes it a subject to provide the filling packaging apparatus of the granular material which enabled it to be filled with a granular material in the flat bag part formed in a long film at high speed.

  The powder filling and packing apparatus according to the present invention is configured to fold a long film conveyed in the length direction into two in a bottomed shape, and seal the long film in the width direction so that an upward insertion port is formed. It is a powder filling device that continuously forms a plurality of flat bag portions provided and fills each flat bag portion from the insertion port, and a fixed amount of powder particles falling from above is provided. A barrel in which a wide chute portion to be received and a flat nozzle portion for discharging the particles are continuously provided in the vertical direction, a number of the barrels are connected in an annular shape, and each barrel is connected to the flat bag portion. And a drive device that inserts the nozzle portion into the flat bag portion only while the powder in the barrel is filled into the flat bag portion. .

  According to this powder filling and packaging apparatus, the powder falling from above the chute is received in the barrel. A constant amount of powder is received in each barrel by keeping the amount of the powder falling at a constant time constant and the conveying speed of the barrel constant. The fixed amount of the powder particles falls from the nozzle portion into the flat bag portion by its own weight while the nozzle portion is inserted into the flat bag portion. The barrel translates with the flat bag portion by the driving device, that is, is conveyed at the same conveyance direction and at the same speed as the flat bag portion. Therefore, the nozzle portion is inserted into the flat bag portion by descending. When the powder in the barrel is completely filled in the flat bag portion, the nozzle portion is discharged from the flat bag portion. In other words, the time during which the nozzle portion is inserted into the flat bag portion and the transport distance are set from the time when all of the powder in the barrel is filled into the flat bag portion.

  In the powder filling and packaging apparatus, it is preferable that the barrel has a forward inclined posture of the chute.

  According to this powder filling and packaging apparatus, the chute part is inclined forward, so that the powder received in the barrel does not accumulate on the inner wall on the rear (upstream) side of the chute part, It can be dropped toward the nozzle part. That is, when the barrel is transported at a high speed, the powder particles falling into the chute are pressed against the inner wall on the rear side of the chute. Therefore, when the chute portion is in a vertical posture, the particulate matter may accumulate on the inner wall on the rear side of the chute portion. However, if the chute part is in the forward tilted posture, the powder particles all fall toward the nozzle part without accumulating on the inner wall on the rear side of the chute part.

  In the powder filling and packaging apparatus, it is preferable that the barrel has a chute portion and a nozzle portion separated, and only the nozzle portion moves up and down.

  According to this powder filling and packaging apparatus, only the nozzle part moves up and down, that is, the chute part does not move up and down. The transport mechanism can be simplified. In the case where the chute is in a vertical posture, the barrel may be formed by integrating the chute and the nozzle, and the chute may be moved up and down.

  In the powder filling and packaging apparatus, it is preferable that the driving device includes an endless belt that holds the barrels and a slide mechanism that moves the nozzle portion up and down.

  According to this powder filling and packaging apparatus, each barrel is held by an endless belt such as a timing belt, whereby each barrel is circulated and conveyed at a constant speed. Further, the belt does not generate metal powder as in the case of using a chain, and is excellent in hygiene. The nozzle portion can be inserted into the flat bag portion only when the nozzle portion moves up and down by the slide mechanism and the powder body is filled in the flat bag portion.

  Further, in the powder filling and packaging apparatus, the slide mechanism holds the base plate fixed to the belt at the same interval as the intervals between the barrels, the nozzle portion, and moves up and down along the base plate. And a plate cam that supports the lower end portion of the slider and moves the nozzle portion up and down so that the nozzle portion is positioned outside and inside the flat bag portion.

  According to this powder filling and packaging apparatus, since the lower end portion of the slider is supported by the plate cam, the slider moves up and down along the plate cam. As the slider moves up and down, the nozzle portion held by the slider moves up and down. The plate cam is displaced downward at the position where the powder is filled in the flat bag portion, and the slider is lowered, whereby the nozzle portion is inserted into the flat bag portion. In addition, when the chute part and the nozzle part are separated as described above, the chute part is held by the base plate, and only the nozzle part moves up and down, and the chute part and the nozzle part are integrally formed The chute also moves up and down integrally with the nozzle.

  Further, in the powder filling and packaging apparatus, it is preferable that the barrel is in contact with the open upper ends of adjacent chute portions.

  According to this powder filling device, the opening edges of the chute portions of each barrel are in contact with each other, so that even if the powder falls continuously into the chute, the powder is adjacent to each other. All are received in the barrel without spilling between the matching chute parts of the barrel.

  In the powder filling and packaging apparatus, the long film is sealed in the width direction in a state where the nozzle portion of the barrel descends and is sandwiched between the two folded long films, and the flat bag It is preferable that a sealing device for forming the part is provided.

  According to this powder filling and packaging apparatus, the nozzle part is not inserted from the insertion port of the flat bag part already formed, but the nozzle part is sandwiched between the long films folded in half. In this state, the sealing device seals the downstream side of the long film in the width direction to form the flat bag portion, whereby the nozzle portion can be inserted into the flat bag portion.

  Moreover, it is preferable that the filling and packaging apparatus for the powder is provided with a fixed amount supply device for discharging a certain amount of the powder falling in the chute in a certain time.

  According to this powder filling and packaging apparatus, the fixed quantity supply device is provided, so that the powder can fall into the chute part for a certain amount of time, and in each flat bag part A certain amount of powder is filled and quality control can be performed accurately.

  According to the present invention, the nozzle portion of the barrel for receiving a certain amount of powder is inserted into the flat bag formed in the long film, and all the powder received in the barrel is a flat bag. By filling the inside of the portion, a certain amount of powder is filled in the flat bag portion. Therefore, productivity can be improved by conveying a barrel and a flat bag part at high speed. As a result, the cost of a product made of a bag body encapsulating particles such as health food and powdered food produced using the powder filling and packaging apparatus according to the present invention can be reduced.

  A powder filling and packaging apparatus according to a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 2, the barrel 10 is provided with a chute portion 11 that receives the particulate matter F falling from above and a nozzle portion 12 that discharges the particulate matter F downward in a vertical direction. It is. The chute 11 is integrally formed with a receiving port 11a that gradually narrows downward from an upper end that opens wide in a rectangular shape, and a connecting portion 11b having a narrow and flat rectangular tube shape. The receiving port 11a is shaped so as to be inclined forward. Moreover, the boundary part of the receiving port 11a and the connection part 11b is made into circular arc shape.

  And the nozzle part 12 is a square cylinder shape one size larger than the said connection part 11b, and is fitted in the state which inserts the connection part 11b. The chute 11 does not move up and down, but the nozzle 12 moves up and down by a slide mechanism 22 described later. Moreover, as shown in FIG. 3, the clearance gap 13 for venting air is provided between the nozzle part 12 and the connection part 11b.

  A large number of such barrels 10 are connected in a track shape by the driving device 20 so that the upper ends of the receiving ports 11a of the adjacent chute portions 11 are joined to each other. That is, the drive device 20 is provided with a line for causing the barrel 10 to go straight. Further, this straight line overlaps with the transport line of the long film 1.

  The drive device 20 includes an endless belt 21 and a slide mechanism 22. The endless belt 21 is hooked by a pair of drive rollers 23, 23, and circulates a large number of barrels 10, 10,. Therefore, it is preferable to use, for example, a timing belt that does not slip. In addition, by using the endless belt 21 as the driving device 20, it can be carried out more hygienically than a chain in which metal dust or the like may be generated.

  On the other hand, as shown in FIG. 3, the slide mechanism 22 includes a base plate 24 fixed to the belt 21 at the same interval as the intervals between the barrels 10, 10,..., A slide rail 25 fixed to the base plate 24 in a vertical posture, A slider 26 that is guided by the slide rail 25 and moves up and down, and a plate cam 27 for inserting and discharging the nozzle portion 12 into and from the flat bag portion 3 are provided. The slide rail 25 may be a groove formed in the base plate 24 in addition to the one protruding from the base plate 24 as shown in the figure, and the slider 26 may be a protrusion formed in the groove.

  The base plate 24 holds the chute 11 by the holder 24a and conveys the chute 11 while maintaining a certain height. The slider 26 holds the nozzle portion 12 by a holder 26a, and the nozzle portion 12 moves up and down when the slider 26 moves up and down. A roller 28 is attached to the lower end portion of the slider 26 so that the slider 26 moves on the plate cam 27 smoothly. As shown in FIG. 2, the plate cam 27 is disposed below the belt 21, and is offset downward only in a range where the nozzle portion 12 is inserted into the flat bag portion 3.

  And the fixed_quantity | feed_rate supply apparatus 30 which drops the granular material F in the barrel 10 in the position where the nozzle part 12 is inserted in the flat bag part 3 is arranged. As shown in FIG. 1, the fixed amount supply device 30 is provided with a hopper 32 for storing the powder F on an electronic balance 31, and a duct 33 for discharging the powder F is attached to the bottom of the end plate of the hopper 32. Thus, the discharge port 34 at the tip of the duct 33 is disposed on the transport line of the chute 11 and above the position where the nozzle 12 is inserted into the flat bag 3.

  Further, the electronic balance 31 confirms the reduced state of the particulate matter F in the hopper 32, and a certain amount (hereinafter referred to as “constant speed”) of the particulate matter F is continuously discharged from the duct 33 at a certain time. The Further, a screw (not shown) is incorporated in the hopper 32 and / or the duct 33 so that the powder F is discharged from the duct 33 at a constant speed.

  The granular material F falling from the duct 33 of the fixed amount supply device 30 is filled in the flat bag portion 3, and the flat bag portion 3 is formed in the width direction by the long film 1 by the sealing device 40. It is formed by being sealed. As shown in FIG. 1, the sealing device 40 includes first and second longitudinal sealing devices 41 and 42 that seal the long film 1 in the width direction, and both side edges of the long film 1 that are separated from each other. There is a lateral sealing device 43 for sealing.

  The long film 1 is drawn out from a roll R arranged on the upstream side, and is formed into a bottomed double fold with a center line as a fold in the middle. The long film 1 folded in half is conveyed so that it goes straight alongside the line where the barrel 10 goes straight.

  The first and second longitudinal sealing devices 41 and 42 are constituted by a pair of rollers 41a, 41a, 42a, and 42a that sandwich the long folded film 1 from both sides, and the surfaces of the rollers 41a and 42a. Heater bars 41b, 41b, 42b, and 42b are provided in a protruding manner. A pair of heater bars 41b, 41b, 42b, and 42b are projected from the surfaces of the rollers 41a and 42a, for example, as shown. In this case, each time the rollers 41a and 42a rotate halfway, the heater bars 41b and 42b heat-seal in the width direction with the long film 1 sandwiched from both sides. Therefore, the heater bars 41b and 42b can be only one or three or more depending on the rotation speed of the rollers 41a and 42a and the width of the flat bag portion 3 to be formed.

  However, it is difficult to insert the nozzle part 12 from the insertion port 3a of the flat bag part 3 after the flat bag part 3 is formed. Therefore, the first vertical sealing device 41 is located at a position where the nozzle portion 12 can be sealed in a state of being sandwiched between the long films 1 folded in half, as indicated by phantom lines in FIG. Be placed.

  Since the long film 1 is conveyed in the length direction, the portion sealed by the first vertical sealing device 41 is conveyed downstream. Therefore, when the first vertical sealing device 41 seals the long film 1 in the width direction in a state where the nozzle portion 12 is sandwiched between the long films 1, the flat bag portion in a state where the nozzle portion 12 is inserted. 3 is formed.

  The second vertical sealing device 42 is disposed downstream of the first sealing device 41, and the surface of the heater bar 42b is formed with irregularities such as knurls to increase the sealing strength and the appearance. The above decorative effect is exhibited. In addition, when the required sealing strength is obtained by the first vertical sealing device 41, the second vertical sealing device 42 can be omitted.

  The horizontal sealing device 43 is composed of a pair of bars 43a and 43a having a length equal to or longer than the interval sealed by the first and second vertical sealing devices 41 and 42. When 43a sandwiches both side edges of the long film 1, this portion is sealed in the lateral direction, and the bag body 2 sealed on three sides is formed.

  On the downstream side of the lateral sealing device 43, rollers 43b and 43b for forming irregularities such as knurls are disposed in the laterally sealed portion. Furthermore, a cutter (not shown) that cuts the portion sealed in the vertical direction is disposed on the downstream side. Further, a dust collector 50 having a groove-like air inlet for sucking in fine particles is disposed along the belt 21 as shown in FIG.

  The powder filling and packaging apparatus according to the first embodiment is configured as described above. Next, a method of filling the powder F into the bag 2 will be described.

  The long film 1 fed out from the roll R is folded in two at the center line, and is conveyed in the length direction as having a bottomed shape, that is, a state in which the upper side is separated. And the flat bag part 3 which sealed in the width direction and provided the upward insertion port 3a by the 1st vertical direction sealing apparatus 41 is formed.

  At this time, as shown in FIG. 2, the nozzle portion 12 of the barrel 10 is lowered and inserted into the flat bag portion 3. That is, the base plate 24 is fixed to the belt 21 that goes straight at the same speed as the long film 1, and the slider 26 that moves up and down along the base plate 24 holds the nozzle portion 12, and the position where the flat bag portion 3 is formed. When the plate cam 27 is displaced downward, the slider 26 is lowered, and the nozzle portion 12 held by the slider 26 is also lowered and inserted into the flat bag portion 3.

  At this time, the chute part 11 receives the particulate matter F falling from the upper duct 33. The powder F falls from the hopper 32 of the fixed amount supply device 30 through the duct 33 at a constant speed and continuously into the barrel 10 by its own weight. Since the barrel 10 is transported at a constant speed, a fixed amount of powder F is supplied into each barrel 10 while the chute 11 passes through the dropping point of the powder F. At this time, since the nozzle portion 12 is inserted into the flat bag portion 3, the powder F does not spill out of the flat bag portion 3.

  Then, as shown in FIG. 2, the powder F falls into the chute 11 due to its own weight, but is pressed against the inner wall of the rear side plate 11c of the chute 11 because the barrel 10 is conveyed at high speed. It will be in the state to be. However, since the chute part 11 is in the forward tilted posture, the particulate matter F falls toward the nozzle part 12 without accumulating on the inner wall of the rear side plate of the chute part 11. Further, since the boundary portion between the receiving port 11a of the chute portion 11 and the connecting portion 11b is formed in an arc shape, the particulate matter F does not accumulate in this portion.

  Moreover, since air venting is provided between the nozzle part 12 and the connection part 11b, the granular material F is smoothly filled in the flat bag part 3 from the nozzle part 12. FIG. It should be noted that even if the fine powder rises after the powder F falls from the nozzle portion 12 and is filled in the flat bag portion 3, the fine powder is sucked into the dust collector 50. It is.

  And all the powder F which fell in the barrel 10 falls in the flat bag part 3, and the predetermined amount of powder F is filled in the flat bag part 3. FIG. Although the barrel 10 and the flat bag portion 3 are conveyed at high speed, a straight line is provided, so that all the powder F that has fallen into the barrel 10 is filled into the flat bag portion 3. . In other words, the straight line is set to a length necessary for filling all the powder F in the barrel 10 into the flat bag portion 3.

  After the powder F is completely discharged from the barrel 10, the slider 26 is guided by the plate cam 27 and is raised, whereby the nozzle portion 12 is discharged above the flat bag portion 3. In FIG. 2, the case where the nozzle portion 12 rises at two pitches is schematically illustrated, but in reality, the nozzle portion 12 may rise at three pitches or more.

  .. Are connected to the belt 21, and the nozzle portions 12 of the barrels 10 are inserted into the flat bag portions 3 formed one after another. Are filled with the powder F one after another.

  In this way, the long film 1 filled with the powder F in the flat bag portion 3 is conveyed to the downstream side, and the second vertical sealing device 42 is already sealed in the width direction. The width direction seal is put on top of. The second vertical sealing device 42 forms irregularities in the seal portion in the width direction and enhances the seal strength. Further, on the further downstream side, the insertion port 3a of the flat bag portion 3 is sealed by the bars 43a and 43a of the horizontal sealing device 43, and the unevenness is formed by the rollers 43b and 43b. Further, on the downstream side, when the cutter is cut in the longitudinally sealed portion, the bag body 2 in which the powder F is enclosed is completed. The bag body 2 can be manufactured, for example, at least 2,000 bags per minute.

  Next, a second embodiment of the powder filling and packaging apparatus according to the present invention will be described with reference to FIG. The powder filling and packaging apparatus according to the second embodiment is characterized in that the rear plate 11c of the receptacle 11a of the barrel 10 and the upper end portion 11d of the front plate are in a vertical posture.

  In such a chute portion 11, the rear plate 11c of the barrel 10 and the upper end portion 11d of the front plate of the barrel 10 are in close contact with each other, and no gap is generated between the side plates 11c and 11d. Therefore, the powder F falling from the discharge port 34 of the duct 33 disposed above the conveyance path of the barrel 10 is surely dropped into the chute 11 without spilling between the adjacent chute 11. In the barrel 10, a certain amount of powder F is received.

  However, when such a barrel 10 is conveyed at high speed, the powder F may be deposited on the inner wall of the rear side plate of the chute portion 11. Therefore, the chute part 11 is made of a material that allows the powder F to slide down. Alternatively, the barrel 10 is transported at a speed at which the powder F does not accumulate on the inner wall of the rear side plate of the chute 11.

  Since the other structure of 2nd Embodiment is the same as 1st Embodiment, the description is abbreviate | omitted.

  Next, a third embodiment of the powder filling and packaging apparatus according to the present invention will be described with reference to FIG. The powder filling and packaging apparatus according to the third embodiment is characterized by using a barrel 10 in which a chute 11 and a nozzle 12 are integrated.

  Therefore, in this barrel 10, the chute 11 is not held by the base plate 24, and the entire barrel 10 is moved up and down by the slide mechanism 22. That is, the chute part 11 and the nozzle part 12 may be held by the slider 26, or only one of the chute part 11 or the nozzle part 12 may be held by the slider 26.

  In addition, the chute portion 11 may have a shape as shown in the first or second embodiment, but may have a funnel shape as shown in FIG. However, the funnel-shaped chute part 11 is more likely to accumulate the particulate matter F on the inner wall than the chute part 11 described in the second embodiment. Therefore, when such a chute | shoot part 11 is used, when the barrel 10 is conveyed at low speed, it can implement suitably.

  Moreover, since the chute | shoot part 11 raises / lowers integrally with the nozzle part 12, the chute | shoot parts 11 of the barrel 10 which adjoins cannot be contact | adhered. Therefore, the cover 14 is provided to prevent the powder F from spilling into the gap even if a gap is generated between the adjacent chute portions 11 and 11.

  The cover 14 is provided by extending the rear side plate 11c so as to cover the upper part between the adjacent chute portions 11, 11. The cover 14 can have an arbitrary shape such as a shape in which the tip portion is bent downward, in addition to the rectangular shape as illustrated.

  Since the other structure of 3rd Embodiment is the same as 1st Embodiment, the description is abbreviate | omitted.

  Note that the present invention is not limited to the above-described three embodiments, and can be variously modified within the scope of technical matters described in the claims. For example, the powder F may not be continuously dropped from the duct 33 but may be dropped intermittently. In this case, a gap may be generated between the chute portions 11 and 11 of the adjacent barrels 10 and 10. Moreover, although the said embodiment demonstrated the case where the barrel 10 which circulates in a track | truck shape fills the granular material F in the flat bag part 3 in an outward path | route, it can implement similarly in a return path | route.
