For example, in the case of the present embodiment, by setting the set number of packages 1 to 30, it is possible to automatically form an aggregate 5 in which 30 packages 1 are integrated.

In the counting automatic integration sorting device 10 of the present embodiment, first, as shown in FIG. 5, the packaging body 1 cut by the cutter portion 6 of the filling and packaging apparatus and discharged one by one is vertically ejected by the guide belt conveyor portion 26. It is inserted between the facing belt surface 28b and the guide member 21.

In the guide belt conveyor section 26, as shown in FIG. 5, the guide belt conveyor section 26 is introduced between the vertical belt surface 28b of the guide belt conveyor section 26 and the guide member 21 by suction from the suction port 29a of the blower suction section 29. The package 1 is held on the vertical belt surface 28b of the belt portion 28 of the guide belt conveyor portion 26. Further, by the rotation of the belt portion 28, the package 1 held on the vertically oriented belt surface 28b is conveyed downward and dropped toward the screw conveyor portion 30 in a vertical posture.

At this time, the photoelectric sensor of the measuring unit 11 detects the package 1 falling from the guide belt conveyor 26 to the screw conveyor 30, and measures the number of packages 1 sent out to the screw conveyor 30 (packaging). Count body 1). Further, the blade portion 60 is on standby in a state of being stopped at the reference stop position.

In the screw conveyor portion 30, the package 1 that falls from the guide belt conveyor portion 26 is inserted between the screw blades 32b of the left and right screw portions 31 in a vertical posture. At the same time, the vertically oriented package 1 inserted between the screw blades 32b is placed and supported on the belt portion 42 of the conveyor belt conveyor portion 40. As a result, the orientation (posture) of the package 1 can be aligned in a certain vertical direction.

At this time, the rotation speed of the belt portion 28 in the guide belt conveyor portion 26 (that is, the transport speed of the package 1) and the rotation speed of the screw portion 31 in the screw conveyor portion 30 are appropriately controlled in correspondence with each other. As a result, the package 1 can be smoothly inserted between the screw blades 32b of the left and right screw portions 31. In particular, in the case of the present embodiment, by controlling the rotation speed of the guide belt conveyor portion 26 and the rotation speed of the screw portion 31, one package 1 is provided at each interval provided between the screw blades 32b of the screw portion 31. It is inserted one by one. As a result, the plurality of packages 1 can be arranged and held in a row at regular intervals along the rotation axis direction of the screw conveyor portion 30 (transfer direction of the package 1).

Further, in the screw conveyor portion 30, the left and right screw portions 31 are rotated at a predetermined speed, and the belt portion 42 of the conveyor belt conveyor portion 40 is rotated according to the transfer speed of the package 1 by the screw conveyor portion 30. As a result, the package 1 inserted between the screw blades 32b is smoothly transferred at a constant speed along the rotation axis direction of the screw portion 31 while maintaining the vertical posture, and as shown in FIG. 6, left and right. Can be guided between the brush portions 51 of the resistance applying portion 50.

The resistance applying portion 50 applies resistance to the package 1 guided between the left and right brush portions 51, and holds the package 1 in a vertical posture. At the same time, the transfer speed of the packages 1 is slowed down to narrow the space between the packages 1. As a result, the package 1 introduced into the resistance imparting portion 50 can be accumulated and put together in a lump.

Then, when the number of packages 1 measured by the measuring unit 11 reaches the set number of 30, the blade units 60 standing by at the reference stop position are bladed as shown in FIG. The drive unit 61 moves the package 1 in the transfer direction. At this time, the blade portion 60 transfers the package 1 by the screw conveyor portion 30 within the installation area of the screw conveyor portion 30 while sliding the pedestal portion 64 fixing the blade portion 60 to the sliding contact plate 65. It moves at the same first movement speed as the speed. As a result, the blade portion 60 is inserted between the 30 packaging bodies 1 and the packaging body 1 subsequently introduced into the screw conveyor portion 30, whereby the blade portion 60 causes the 30 packaging bodies 1 to be inserted. Can be sorted (sorted) from the subsequent packaging body 1.

Further, the blade portion 60 moving at the first moving speed passes through the installation area of the screw conveyor portion 30 and then enters the installation area of the resistance applying portion 50. In the present embodiment, when the blade portion 60 enters the installation area of the resistance applying portion 50, the moving speed of the blade portion 60 is increased, and the blade portion 60 is moved at a second moving speed faster than the first moving speed described above. Move. As a result, as shown in FIG. 7, the 30 packaging bodies 1 are easily separated from the succeeding packaging body 1, and a space portion is provided between the 30 packaging bodies 1 and the succeeding packaging body 1. Can be provided. At the same time, 30 packages 1 can be put together to form one aggregate 5, and the aggregate 5 can be extruded to the downstream side of the resistance applying portion 50 as shown in FIG.

Then, the aggregate 5 of the package 1 extruded to the downstream side of the resistance applying portion 50 as described above is collected by the operator. Further, the aggregate 5 of the 30 packages 1 collected by the worker is then boxed, wrapped with a film, or the like. In the present embodiment, for example, the left and right conveyor belt conveyors 40 are formed by extending them for a long time, and at the downstream end of the conveyor belt conveyor 40, storage boxes for accommodating the formed aggregates 5 are arranged one by one. It is also possible to automatically pack the aggregates 5 one by one into the storage box by sending them to the storage box.

On the other hand, the blade portion 60, which is the assembly 5 of the package 1 pushed out from the resistance applying portion 50, reaches a position where the pedestal portion 64 fixing the blade portion 60 exceeds the tip of the sliding contact plate 65 by the blade driving portion 61. When it moves, it rotates and is conveyed so as to fall backward as shown by a virtual line in FIG. 8 due to the weight of the blade portion 60 or when the blade portion 60 comes into contact with one end of the support plate portion 43. It moves below the belt portion 42 of the belt conveyor portion 40. Further, the blade drive unit 61 stops the other blade unit 60 (the other blade unit 60 of the two blade units 60) provided in the automatic counting and sorting device 10 as a reference as shown in FIG. Move to the position and stop.

In the counting automatic accumulation sorting device 10 of the present embodiment, as described above, 30 packages are sequentially received by the introduction unit 20 (see FIG. 5) from the work of sequentially receiving the packages 1 that fall one by one from the filling and packaging device. By continuously and repeatedly pushing the aggregate 5 of 1 to the downstream side of the resistance applying portion 50 by the blade portion 60 (see FIG. 8), the aggregate 5 of the package 1 is pushed one after another at regular intervals. It can be formed automatically.

Therefore, according to the counting automatic accumulation sorting device 10 of the present embodiment, the work of forming a predetermined number of aggregates 5 by aligning the orientations of the plurality of packages 1 as conventionally performed manually is performed. It can be done automatically and stably. As a result, the burden on the operator can be significantly reduced, and the work speed and work efficiency in the work of accumulating the package 1 can be greatly improved.
