Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a magazine for a bag feeder, which accommodates a large number of bags and supplies them one by one in an automatic packing machine for packing foods and the like.

[0002]

[Prior art]

 As shown in FIG. 4, for example, a packaging system of an automatic packaging machine for foods, etc., takes a bag P one by one from a magazine A containing a large number of bags P filled with a filling material and supplies the bag P (1 ), A marking process (2) for marking the date of manufacture of the product on the bag P, an opening process (3) for opening the mouth of the supplied bag P, a filling process from the storage tank G storing the filling such as food. Filling step (4) for filling the inside of the bag P, closing step (5) for closing the mouth of the bag P, primary sealing step (6) and secondary sealing step (7) for sealing the bag P, packaging completion The bag P is composed of a discharging step (8) for discharging the bag P to the outside or the next step, and the bag P is rotated together with the table T around a table T which is intermittently rotated at a predetermined speed. In this case, the operation for the bag P is continuously performed.

As shown in FIGS. 5 and 6, the magazine A used in the bag feeding step (1) includes a bottom plate 1, a front plate 2, a pair of left and right side plates 3a and 3b, a vertically movable receiving plate 4, and the like. The plurality of bags P stacked on the receiving plate 4 are sucked by the suction cups one by one from above and supplied.

When the number of bags P in the magazine A decreases, the electric motor 5 is driven each time, and the legs 8 of the receiving plate 4 are raised via the pinion 6 and the rack 7 to slightly raise the uppermost surface of the bags P. When the bags P in the magazine A are running low, the bags P are newly replenished. The bags P stacked on the receiving plate 4 in the magazine A are restricted in movement by the front plate 2 in the front-rear direction and by the pair of side plates 3a, 3b in the left-right direction. Therefore, when the size of the bag P changes, it is necessary to adjust the mutual distance between the side plates 3a and 3b according to the size. Regarding the front-rear direction, since the entire magazine A is slightly inclined forward, the bag P is received by the front plate 2, and it is not necessary to adjust even if the size of the bag P changes.

As a means for adjusting the mutual distance between the side plates 3a, 3b, as shown in FIG. 6, the left screw part 9a and the right screw part 9b of the screw shaft 9 are screwed onto the pair of side plates 3a, 3b, respectively. By rotating the handle 10, the two side plates 3a and 3b are moved in opposite directions to adjust the distance.

[0006]

[Problems to be solved by the device]

 In the conventional side plate spacing adjusting means in such a magazine A, the amount of movement of the side plates 3a and 3b for each one rotation of the handle 10 is extremely small, so that a considerable amount of time is required for the adjustment. An object of the present invention is to provide a bag feeder magazine in which the mutual spacing between the side plates can be easily and quickly adjusted according to the size of the bag used.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the bag feeder magazine according to the present invention, the left and right side plates facing each other with the receiving plates on which a large number of bags are placed are rotated about the vertical rotation axis. It is characterized in that it is provided with side plate spacing adjusting means for simultaneously moving in the opposite direction, and drive means for driving the rotating shaft by an electric motor.

[0008]

[Action]

 In the bag feeder magazine having the above-mentioned structure, both side plates are simultaneously moved in opposite directions by rotating the central axis in the vertical direction by the electric motor to adjust the distance between the side plates.

[0009]

【Example】

 The present invention will be described in detail with reference to the embodiments shown in FIGS. The same reference numerals as those in FIGS. 5 and 6 indicate the same members.

FIG. 1 is a front view showing an embodiment of a bag feeder magazine according to the present invention, and FIG. 2 is a plan view thereof. As shown in FIG. 5, the magazine A according to the present invention is also composed of a bottom plate 1, a front plate 2, a pair of left and right side plates 3a and 3b, a receiving plate 4, etc., and a receiving plate 4 in which a large number of bags P are stacked. It is the same as the conventional one, but the rotatable pinion 12 supported by the rotating shaft 11 oriented in the vertical direction is arranged in the center, and the pair of racks 13 a are sandwiched by the pinion 12. , 13b mesh with the pinion 12. The side plates 3a and 3b are erected on the racks 13a and 13b, respectively, and are fixed by bolts 14a and 14b. Further, guides 15a and 15b are provided on the bottom plate 1 to facilitate the movement of the racks 13a and 13b. The rotating shaft 11 is driven by an electric motor (not shown).

In this embodiment, when the pinion 12 is rotated right or left by the rotating shaft 11, the racks 13a and 13b simultaneously move in opposite directions, and the pair of side plates 3a and 3b also move together with the racks 13a and 13b. The mutual distance between the side plates 3a and 3b is adjusted. In this way, the mutual distance between the side plates 3a and 3b can be adjusted according to the size of the bag P to be used.

In the above-mentioned embodiment, the pinion 12 and the pair of racks 13a and 13b meshing with the pinion 12 are used as the side plate spacing adjusting means. However, as another embodiment, a pantograph type as shown in FIG. A link mechanism may be used. In FIG. 3, the two links 20a and 20b are pivotally attached to the centers of the links 20a and 20b by a rotary shaft 21, and the ends of the links 20a and 20b on the side plate 3a side have respective ends of the links 22a and 22b. Is rotatably connected, the other ends of the links 22a and 22b are pivotally attached to the side plate 3a by a pin 23, and the other ends of the links 20a and 20b are the side plates 3b via the links 24a, 24b and the pin 25. Each of them is rotatably pivoted.

Therefore, when the rotary shaft 21 is turned to the right, for example, the side plates 3a, 3b are moved inward by the link mechanism and the mutual distance between the side plates 3a, 3b is narrowed. Conversely, the rotary shaft 21 is moved to the left side. When turned, the side plates 3a, 3b move outward and the mutual distance between the side plates 3a, 3b becomes wider.

Therefore, similar to the previous embodiment, the mutual distance between the side plates 3a and 3b can be easily adjusted according to the size of the bag P to be used.

[0015]

[Effect of device]

 As described above, in the bag feeder magazine according to the present invention, both side plates facing each other can be moved in the same pair and in opposite directions by simply rotating the rotating shaft by the electric motor. It is possible to easily adjust the mutual distance between the left and right side plates according to the above, and the time required for the adjustment can be greatly shortened.
