  In addition, when the bottle product (A) (A) stocked at the relay station (4) is pushed by the transfer rod (12) and transferred to the filling conveyor (15), the bottle product (A) (A) is transferred to the end. When the front row slides on the relay station (4) or transfers from the relay station (4) to the filling conveyor (15), there is a concern that the front row may fall. In particular, in the case of high-speed packaging or in a pressure-resistant bottle (bottle filled with carbonated beverage or the like) in which the lower part is formed in a five-leg shape or the like, it is extremely easy to fall down because of poor stability. If the bottle products (A) and (A) fall during high-speed packaging, the subsequent bottle products (A) and (A) that are being transported fall one after the other, and the fall bottle fills the transport path. However, much time is required for the subsequent recovery work.

The transfer crane (5) is controlled so as to fill the bottle products (A) and (A) from the end on the packing side with respect to the semi-shaped case (25) conveyed by the case conveyor (21). The

In addition, on the side of the case conveyor (21), there is a fall prevention guide (61) (61) that moves while facing each other while approaching the lower part of the boxed side end of the case (25) in a semi-shaped state. A guide conveyor (6) is provided.
Further, flap folding devices (7) such as flap folding swing plates (71) to (74) and inclined top plates (75) are disposed in the vicinity of the traveling area of the case conveyor (21). .

Details of each part will be described below.
[Grouper (G)]
As shown in FIGS. 1 and 2, the supply conveyor (10) hangs seven unit belts (100) (100) having a narrow width on the outer periphery of the drive roller (14) and the driven roller (19) in a parallel state. The bottle products (A) and (A) can be conveyed in six rows by the unit belts (100) and (100). The bottle product (A) (A) is supplied to the supply conveyor (10) from a wide carry-in conveyor (not shown).

  Above the supply conveyor (10), there are provided seven lane guides (13) (13) arranged side by side in the conveyor width direction at an interval substantially equal to the width of the bottle product (A), The bottle products (A) and (A) pass through the six bottle lanes (130) and (130) between the seven lane guides (13) and (13).

  The grouper body (3) constituting the grouper (G) together with the supply conveyor (10) and the lane guides (13) and (13) is a bottle that passes through the bottle lanes (130) and (130) closely in the conveying direction. Underer provided with fingers (31) and (31) that sequentially enter between the products (A) and (A) at a predetermined pitch (in this embodiment, four bottle products (A) and (A)). A chain (30) is hung around a drive sprocket (36) and driven sprockets (37) (37). The under chain (30) travels at a slower speed than the supply conveyor (10).

  The fingers (31) and (31) are arranged between the unit belts (100) and (100) in the width direction from below the traveling area of the unit belts (100) and (100) constituting the supply conveyor (10). The bottle products (A) and (A) are inserted between each other in the conveying direction. When the fingers (31) (31) that move at a lower speed than the supply conveyor (10) enter between the conveying directions of the bottle products (A) (A), the bottle products on the unit belts (100) (100) (A) The movement speed of (A) is decreased.

  Accordingly, the operation of inserting the finger (31) from below between the bottle products (A) and (A), and the other finger (31) preceding the finger (31) is lowered and the bottle products (A) and (A). 4 bottle products (A) and (A) between fingers (31) and (31) adjacent in the transport direction are transported at the transport speed of the unit belt (100) and (100) by the operation of removing from the downstream direction. Can be taken out to station (4). That is, when the finger (31) is lowered from between the bottle products (A) and (A), the bottle products (A) and (A) whose movement speed is regulated by the fingers (31) are the unit belt (100). It moves at a conveying speed of (100) and gradually moves away from the finger (31), whereby the bottle products (A) and (A) are taken out to the relay station (4).

  The bottle products (A) and (A) taken out to the relay station (4) were grouped in a matrix of 4 rows and 6 columns by the lane guides (13) and (13) and the fingers (31) and (31). At the same time, the front row of the bottle products (A) and (A) is stocked in the relay station (4) while being blocked by the relay stopper (40).

[Transport crane (5)]
As shown in FIG. 1, the transfer crane (5) for taking out the bottle products (A) (A) from the relay station (4) is arranged on the base (50) and the base (50) so as to be freely rotatable. The holding column (54) through which the advancing / retracting arm (53) is slidably inserted at the upper end of the rotating column (51) is vertically and horizontally mounted by the support shaft (55). It is attached so as to be rotatable in the direction. Further, a head block (56) (corresponding to the holding body as the above-described invention specific matter) is swingably attached to the tip of the advance / retreat arm (53) by a support shaft (57).

  Accordingly, the horizontal rotation of the swivel column (51) relative to the base (50), the vertical rotation of the holding cylinder (54) relative to the swivel column (51), and the axial direction of the advance / retreat arm (53) relative to the holding cylinder (54) By moving and swinging the head block (56) at the tip of the advance / retreat arm (53), the bottle product (A) (A) of the relay station (4) is moved to a specific case on the case conveyor (21) ( 25) Can be transferred to part.

The head block (56) is specifically configured as shown in FIGS. 3 to 5. FIG. 3 is a longitudinal sectional view of the head block (56), and FIG. 4 is a bottom view thereof.
The outer frame (560) of the head block (56) is formed in a rectangular box shape opened downward, and a cylinder (563) is formed on the outer surface of the pair of opposing side walls (561) (562) of the outer frame (560). (564) are installed separately. Then, by means of piston rods (563a) (564a) of the cylinders (563) (564), a head mounting base (82) for grip heads (81) (81) holding bottle products (A) (A) described later. ) (82) are pushed in a direction approaching each other.

Parallel guide rods (565) (566) are installed between the opposing side walls (561) (562) of the outer frame (560), and the guide rods (565) (566) are connected to the head mounting base (82 ) (82) is inserted through a guide insertion hole (82a) penetrating in the side wall so as to be relatively slidable.
Further, four grip heads (81) (81) are mounted in the longitudinal direction on the lower surface of each head mounting substrate (82), and the grip heads (81) (81) are attached to the bottle product (A). (A) When the vacuum device (not shown) is externally fitted to the upper end of the bottle mouth, the grip head (81) (81) presses and grips the bottle mouth from the outer peripheral direction. The products (A) and (A) can be held in a suspended state by the grip heads (81) and (81).

  On the other hand, standing flanges (82b) and (82b) project from the upper end of the side surface of the head mounting base (82). Then, the interval setting shaft (83) is inserted into the through holes (820) (820) penetrating through the upright flanges (82b) (82b) located on the facing surfaces of the adjacent head mounting bases (82) (82). (83) is loosely inserted, and stoper nuts (84) and (84) are screwed to both ends of the interval setting shafts (83) and (83). Further, the upright flanges (82b) and (82b) are urged in directions away from each other by kick springs (85) and (85) bent in a U-shape.

  Therefore, when the piston rods (563a) (564a) of the cylinders (563) (564) are advanced with the grip heads (81) (81) holding the bottle products (A) (A), the head mounting substrate (82) (82) slides on the guide rods (565) (566) and approaches each other (the state of FIG. 5), thereby the bottle products (A) (A) on the relay station (4). Even if there is a gap (gap equivalent to the thickness of the lane guide (13)) between each row, it will disappear and the bottle products (A) and (A) will be densely packed. Easy to do.

  On the other hand, when the piston rods (563a) and (564a) are retracted after the bottle products (A) and (A) are filled in the case (25), the head mounting bases (82 ) (82) returns from the approaching state of FIG. 5 to the separated state of FIG. 3, so that the bottle products (A) (A) stocked in the relay station (4) (lane guides (13 ) (13) is formed in the gap corresponding to the thickness)).

[Case conveyor (21)]

On the conveyor belt (210), upright plates (211) (211) provided at positions where the case (25) is sandwiched from the front and rear in the conveying direction are arranged at a predetermined pitch. And between these upright plates (211) (211) is a bucket part (212) that conveys the case (25), and a sheet stock part that holds the blank sheet that unfolds the case (25) (25) ( When one blank sheet is taken out from 22), it is shaped into a half-shaped case (25) in which one side in the horizontal direction (conveyor width direction) and the upper side are opened by a shaping guide (not shown) and the case conveyor (21 ) Is set in the upper bucket section (212).

  As shown in FIGS. 6 and 7, front and back lower flap guides (201) and (202) extending along the case conveyor (21) are provided on both sides of the case conveyor (21). As shown in FIG. 7, the lower flap (252) located at the box side end of the case (25) moves in the conveying direction while contacting the front lower flap guide (201) while being folded downward. It is like that. On the other hand, the back lower flap guide (202) is moved in the conveying direction while being in contact with the rear lower flap (253) of the case (25) in the upwardly folded state. Further, in the semi-shaped state shown in FIG. 7 (in this state, the bottle products (A) and (A) are filled), the rear side flaps (254) and (255) are also bent inward, When the bottle product (A) (A) is put into the case (25) from the transfer crane (5), the bottle product (A) (A) falls backward (side flap (254) (255) side). I am less worried.

  Further, as shown in FIG. 1, swing folding plates (71) to (74) and an inclined top plate (75) for folding the flap are arranged in a range along the traveling area of the case conveyor (21). These sets constitute a folding device (7).

The swing plate (71) is a pair of side flaps (250) (251) (a pair of side plates bent up from the front and rear ends in the transport direction of the bottom plate (259) ( 260) and (261) are folded in the closing direction. Similarly, the swing plates (72) and (73) are upper flaps (257) and (258) extending from both ends of the cover plate portion (256) in the conveyor width direction, and the swing plates (74) are lower flaps (252). Each has a function of folding in the closing direction. In addition, the lid plate portion (256) connected to the upper side of the side plate portion (261) bent up from the front end of the bottom plate portion (259) in the conveying direction passes through the inclined top plate (75) portion. The top plate (75) is pressed down and closed.
Although not shown, a glue spray gun for adhering the adhesive to each flap is disposed in the traveling area of the case conveyor (21), and the flaps are overlapped with the adhesive from the glue spray gun. The mating portion is configured to be adhesively fixed.

[Guide conveyor (6)]
As shown in FIG. 1, the guide conveyor (6) arranged side by side on the case conveyor (21) hangs an endless belt (65) between the driving roller (62) and the driven roller (63). It is a turn. As shown in FIGS. 1, 8, and 9, the endless belt (65) freely penetrates between the side flaps (250) and (251) when the driven roller (63) is raised. Flap release plates (66) (66), which are flap release means for holding in an open posture gradually separated toward the end side, are disposed at a predetermined pitch. The pair of flap release plates (66) and (66) are arranged in plan view so that the distance between them becomes narrower as they approach the case conveyor (21) so that the side flaps (250) and (251) can be held in the opened posture. And it is slanted into a square shape.

  Therefore, the bottle product (A) (A), in particular, the rectangular tube-shaped bottle product (A) (A) is moved from the boxed side end into the case (25) while being suspended by the transfer crane (5). In this case, since the side flaps (250) (251) that move away toward the free end side function as guides for the bottle products (A) (A) that move toward the case (25), the bottle products ( A) (A) can be filled smoothly.

Also, the endless belt (65) is transported to the case while facing the lower end of the boxed side end (S) (the end of the transfer crane (5) side) of the case (25) in a semi-shaped state. A fall prevention guide (61) (61) that moves in the direction is provided. Specifically, the overturn prevention guides (61) and (61) are bent in a direction approaching each other from the lower ends of the pair of flap opening plates (66) and (66).
FIG. 10 is an operation explanatory diagram when the bottle product (A) (A) is filled in the case (25) in the semi-shaped state.

  The bottle product (A) (A) suspended from the head block (56), which is the holder of the transfer crane (5), crosses the upper adjacent part of the fall prevention guide (61) horizontally to the case (25) side. After that, the head block (56) of the transfer crane (5) descends by almost the height of the fall prevention guide (61). Then, the bottom surfaces of the bottle products (A) and (A) land on the bottom plate portion (259) of the case (25), and in this state, the bottle holding state by the grip heads (81) and (81) is released. Thereby, the bottle products (A) and (A) can be filled from the boxed side end (S) into the case (25) in the semi-shaped state.

In this case, when the bottle holding state by the grip head (81) (81) is released, especially when filling at high speed, the bottle product (A) (A) becomes unstable temporarily and easily falls, but the bottle product ( A) The fall prevention guide (61) faces the lower side surface of (A) (see FIG. 9). Therefore, it is possible to prevent the bottle products (A) and (A) from being overturned by the overturn prevention guides (61) and (61) that face the lower side surfaces of the bottle products (A) and (A).
In the above embodiment, the fall prevention guides (61) and (61) are connected to the flap release plates (66) and (66) disposed on the case conveyor (21), but as shown in FIG. A fall prevention guide (67) independent of the flap release plates (66, 66) may be fixed to the case conveyor (21).

<< Second Embodiment >>
