Specifically, a device is known that sets a bag under a hopper, opens the bag under the hopper with wind, and puts vegetables such as leek and leaf ginger bundled through the hopper and performs bagging. Yes.

  However, in such a bagging apparatus, when vegetables are put into the hopper, the roots of the vegetables may be caught in the mouth of the bag or the mouth of the bag may be turned up due to friction between the bag and the vegetable. There was a problem that the bagging of can not be performed smoothly.

  As a method for solving such a problem, for example, it is conceivable that the opening of the bag is made larger than the lower end opening of the hopper. However, when such a solution is taken, the bag becomes large with respect to the vegetables, so there are problems in terms of cost and appearance, and it is not a fundamental solution.

  Thus, for example, in the bag filling described in Patent Document 1, a configuration is disclosed in which the lifting cylinder and the engagement plate are slid down into the bag by stepping on the foot. If such a bagging apparatus is used, a guide cylinder or plate is provided at the opening edge of the bag, so that the possibility of the bag opening being turned up can be reduced.

At this time, as shown in FIGS. 3 and 4, the blower nozzle 51 is arranged at a position that does not overlap the lower end opening 34 of the hopper 30 when viewed from directly above. For this reason, the blowing nozzle 51 is not provided vertically above the lower end opening 34 of the hopper 30, and the blowing nozzle 51 does not exist on the passage path of the packaged object 200, so that the packaged object 200 can be made smooth. It can be put into.

  Further, the hopper 30 is formed so that the side surface opposite to the air blowing nozzle 51 is vertical when the bagging device 10 is placed on a horizontal base 100 as shown in FIG. . A long flap insertion hole 32 is formed in the vertical side wall as a horizontal long hole into which a long flap 60 described later can be inserted. In addition, short flap insertion holes 33 are formed in the left and right side wall portions as viewed from the long flap insertion hole 32 as horizontal long holes into which a short flap 70 described later can be inserted.

(Flap 60, 70)
The bagging apparatus 10 according to the present embodiment includes three plate-like flaps that can swing inside the hopper 30. Specifically, it has one long flap 60 and two short flaps 70.

  The long flap 60 is provided so as to penetrate the long flap insertion hole 32 described above, and is supported swingably on the opening edge of the long flap insertion hole 32. 2 to 4, the long flap 60 is a substantially L-shaped metal fitting refracted at a substantially center, and as shown in FIG. 2, a weight piece 61 and an inner tongue piece 62 with a refracted portion interposed therebetween. And form.

  The long flap 60 is inserted into the long flap insertion hole 32 so that the refracted portion is a peak, and the weight piece 61 protrudes outside the hopper 30 and the inner tongue piece 62 protrudes inside the hopper 30. ing. For this reason, the long flap 60 is swingably supported by the opening edge of the long flap insertion hole 32 with the refracted portion as a fulcrum.

  Since the long flap 60 is formed so that the weight piece 61 is heavier than the inner tongue piece 62, the weight piece 61 is possible in a free state (except when the packaged article 200 is loaded). It hangs down as much as possible. In other words, the inner tongue piece 62 is formed to be lifted up as much as possible, and at this time, the inner tongue piece 62 takes a standby posture above the lower end opening 34 of the hopper 30.

  The short flap 70 is provided so as to penetrate each of the two short flap insertion holes 33 described above, and is swingably supported by the opening edge of each short flap insertion hole 33. 2 to 4, the short flap 70 is a substantially L-shaped bracket that is refracted at a substantially center, and as shown in FIG. 2, the weight piece 71 and the inner tongue piece 72 with the refracted portion interposed therebetween. And form.

  The short flap 70 is inserted into the short flap insertion hole 33 so that the refracted portion becomes a peak, the weight piece 71 protrudes outside the hopper 30, and the inner tongue piece 72 protrudes inside the hopper 30. ing. For this reason, the short flap 70 is swingably supported by the opening edge of the short flap insertion hole 33 with the refracted portion as a fulcrum.

  Since the short flap 70 is formed so that the weight piece 71 is heavier than the inner tongue piece 72, the weight piece 71 is possible in a free state (except when the packaged article 200 is loaded). It hangs down as much as possible. In other words, the inner tongue piece 72 is formed so as to be lifted up as much as possible, and at this time, the inner tongue piece 72 takes a standby posture above the lower end opening 34 of the hopper 30.

  As shown in FIG. 3, the flaps 60 and 70 are provided so as not to interfere with each other, and are formed so as not to touch when swinging.

(Pressing bracket 40)
The pressing metal fitting 40 is for holding the upper end of the bag 300 below the hopper 30 in combination with the locking protrusion 53 described above.

  As shown in FIG. 4, the pressing metal fitting 40 is biased forward by a spring 41 and biases the bag 300 locked to the locking protrusion 53 forward. Specifically, as shown in FIG. 2, a semicircular arc-shaped holding portion 42 is provided in the middle of the pressing metal fitting 40, and the bag 300 extends along the outer peripheral surface of the hopper 30. It is formed so as to press forward. Further, a pressing piece 43 is provided at the tip of the pressing metal fitting 40, and the pressing piece 43 urges the vicinity of the opening 302 of the bag 300 to protrude slightly forward, so that the opening 302 is likely to receive air blow. I am doing so.

  By the way, as shown in FIG. 9, the bag 300 used in the bag filling device 10 according to the present embodiment includes a main body 301 that forms a bag portion, and a holding portion 303 provided at the upper end of the main body 301. Become. A perforation 304 is provided between the main body 301 and the holding portion 303 so that the two can be separated. The bag filling device 10 according to the present embodiment uses a plurality of the bags 300 in a stacked manner. For this reason, when the article to be packaged 200 is inserted into the bagging apparatus 10 and the article to be packaged 200 enters the bag 300, the main body 301 is separated from the perforated line 304 by the weight of the article to be packaged 200. The main body 301 of the next bag 300 is pushed out to the forefront. And since the main body 301 of the frontmost bag 300 is urged forward by the pressing piece 43 of the pressing metal 40 described above, even when the main body 301 is cut off more and more and the number of bags 300 is reduced, Of the remaining bags 300, the air is reliably blown to the opening 302 of the frontmost bag 300 so that the bag 300 opens. That is, as shown in FIG. 9, in the present embodiment, the holding portion 42 of the pressing metal fitting 40 and the pressing metal fitting 43 urge the bag 300 forward below the perforation 304. For this reason, the bag 300 can be pushed forward by the amount that has been cut and thinned while in use, and the bag 300 can be reliably blown into the opening 302 even if the bag is reduced. Thus, the bag 300 is opened.

(Description of the operation of the bagging device 10)
Next, the operation of the bag filling device 10 will be described.

  FIG. 4 is a side cross-sectional view of the bag filling device 10 and shows how air is blown. As shown in FIG. 4, the bag 300 is held obliquely so that the lower portion is pushed forward slightly, and the vicinity of the opening 302 is further urged forward by the pressing piece 43 of the pressing fitting 40. For this reason, the wind blown out from the blowing nozzle 51 hits the portion of the edge of the opening 302 of the bag 300 in the foremost row of the stacked bags. For this reason, the bag 300 in the foremost row is formed so as to open by blowing air, and the bag 300 is opened under the lower end opening 34 of the hopper 30.

  FIGS. 5-8 is a figure for demonstrating the action | operation state of the flaps 60 and 70 when the to-be-packaged object 200 is thrown into the bag filling apparatus 10, Comprising: These are arranged in time series order. Hereinafter, the operating state of the bagging apparatus 10 will be described based on these drawings.

  First, FIG. 5 is an explanatory diagram showing a standby state of the flaps 60 and 70. As shown in FIG. 5, in the standby state, the inner tongue piece 62 of the long flap 60 and the inner tongue piece 72 of the short flap 70 are both lifted upward by their own weights in a direction to close the inside of the hopper 30. It is positioned and takes a standby posture above the lower end opening 34 of the hopper 30.

  In this state, when a packaged object 200 such as a bundle of leek or leaf ginger is inserted, the inner tongue pieces 62 and 72 come into contact with the lower end of the packaged object 200 as shown in FIG. Pushed in.

  Further, when the article to be packaged 200 moves downward in the hopper 30, as shown in FIG. 7, the tips of the inner tongue pieces 62 and 72 swing further downward, and the tips of the inner tongue pieces 62 and 72 are hoppers. It hangs down below the lower end opening 34 of 30. Since the long flap 60 is provided on the vertical side surface of the hopper 30, the inner tongue piece 62 of the long flap 60 hangs down in a substantially vertical direction, and the long flap 60 is placed on the trajectory of the package 200. The tongue piece 62 is formed so as not to protrude.

  When the article to be packaged 200 passes through the hopper 30 in this state, as shown in FIG. 8, the inner tongue pieces 62 and 72 are placed inside the edge of the opening 302 of the bag 300. The object 200 is prevented from touching the edge of the opening 302 of the bag 300.

  And after the to-be-packaged product 200 has completely passed through the hopper 30, the main body 301 of the bag 300 in the front row is separated from the perforation 304 and dropped, and then returns to the standby state shown in FIG. Thereafter, the operations shown in FIGS. 5 to 8 are repeated.

  As described above, according to the bagging apparatus 10 according to the present embodiment, the inner tongue pieces 62 and 72 of the flaps 60 and 70 are pushed and shaken by the package object 200 when the package object 200 passes. It is formed to move and hang down below the lower end opening 34 of the hopper 30. Therefore, the inner tongue pieces 62 and 72 of the flaps 60 and 70 are formed so as to hang down to the inner edge of the opening 302 of the bag 300, and the package object 200 is not caught in the opening 302 of the bag 300. And after the to-be-packaged product 200 passes, the inner tongue pieces 62 and 72 of the flaps 60 and 70 are formed so as to be lifted inside the hopper 30 and take a standby posture above the lower end opening 34 of the hopper 30. Yes. For this reason, the inner tongue pieces 62 and 72 of the flaps 60 and 70 do not obstruct the opening of the bag 300 held below the hopper 30. As described above, the bag filling device 10 according to the present embodiment prevents flaps 60 and 70 from automatically swinging and prevents the article to be packaged 200 from being caught in the opening 302 of the bag 300, and the opening of the bag 300. Thus, the bag can be smoothly filled without causing an operation burden on the operator.

  Further, since the flaps 60 and 70 are formed so as to take the standby posture by their own weight, the operation mechanism of the flaps 60 and 70 can be configured without using a special mechanism such as a spring.

  In addition, since the hopper 30 has a cylindrical shape that tapers as it goes downward, the input port 31 for the package object 200 is formed large, and the package object 200 can be easily input.

  Further, since the long flap 60 is provided on the side surface of the hopper 30 on the side opposite to the side where the bag 300 is held, the long flap 60 is provided at the position farthest from the holding place of the bag 300, in other words, A long flap 60 is provided at a position where the article to be packaged 200 is most easily caught. For this reason, the object 200 can be effectively prevented from being caught.

  Further, since the side surface of the hopper 30 provided with the long flap 60 is formed to be vertical, when the long flap 60 is pushed by the article to be packaged 200 and swings, it faces the vertical direction. Thus, the swinging long flap 60 does not block the path of the article to be packaged 200.

  In the above-described embodiment, the bag 300 is held by the pressing metal fitting 40 and the locking projection 53, but the present invention is not limited to this. That is, the bag 300 may be held by providing a clip or the like, or the bag 300 may be held by a separate holding means.

  Further, in the above-described embodiment, the flaps 60 and 70 are formed by a substantially L-shaped metal fitting, but the present invention is not limited to this. That is, the flap may be swingable so that the straight plate-like flap is pivotally attached to the inner peripheral surface of the hopper 30.

  Further, in the above-described embodiment, the flaps 60 and 70 take the standby posture due to their own weight, but the present invention is not limited to this. That is, it may be formed so as to take a standby posture by the elasticity of the spring or the flap itself.
