[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

As shown in FIGS. 1 and 2, two rows of belt-driven roller conveyors 1 are connected to a belt-driven roller conveyor 2 that is faster than this roller conveyor 1, and this roller conveyor 2 is moved up and down by an air cylinder or the like. The three converters 4 and 5 are successively connected through a stopper 3. These three converters 4,5
is formed by a movable stopper 6 and a fixed stopper 7 that are moved up and down by an air cylinder or the like, and empty cases A _s ,
It consists of a chain conveyor 8 that conveys A _c , and a roller conveyor 9 that is moved up and down above or below this chain conveyor 8. For example, as shown in FIG. It is moved up and down by an air cylinder 11 via a crank 10 or the like.

Further, a roller conveyor 12 is connected to the output side of the converter 5 in the center, and a chain conveyor 13 and a belt conveyor 14 are sequentially connected to the output sides of the converters 4 on both sides. In the middle of the chain conveyor 13, as shown in FIG. A turn stopper 18 is protruded from the inner frame at a fixed position on the belt in the middle of the belt. Further, a stopper 19 that is moved up and down by an air cylinder or the like is provided at the tip of the belt conveyor 14 on both sides, and an interlocking stopper 20 is provided at the tip of the roller conveyor 12.

This interlocking stopper 20 is connected to the empty case in the connected state.
As shown in _Fig . 4, a lever 23 is rotatably attached to a frame 21 with a support shaft 22, and cam follower rollers 24 are attached to both ends of this lever 23. In addition, the upstream side locking plate 28 and the downstream side locking plate 29 are each attached to the frames 25 and 26 by a plurality of sets of guide rollers 27 so as to be movable up and down, and the locking plates 2 on both sides
The cam follower roller 24 is fitted between a pair of upper and lower L-shaped plates 30 fixed to opposing surfaces of the cam follower rollers 8 and 29, respectively. A piston rod 32 of an air cylinder 31, which is pivotally supported at the lower part of the frame 26, is connected to the downstream locking plate 29 by a pin 33. Note that this downstream locking plate 29 has a concave lower portion, so although it appears to overlap with the air cylinder 31 in the drawing, they do not interfere with each other. Then,
When the air cylinder 31 causes the downstream side locking plate 29 to protrude above the roller 12a as shown in the figure, the upstream side locking plate 28 is moved by the action of the lever 23 with the support shaft 22 as a fulcrum. The downstream locking plate 29 locks the empty case A _c1 as shown in the figure. When the upstream locking plate 28 is retracted until the roller 12
It protrudes slightly above a and locks the rear empty case A _c2 . There is a risk that the previous empty case A _c1 will be subjected to the pushing up action of the upstream locking plate 28, but due to the short action time and the ratio of the lever 23, the pushing stroke of the upstream locking plate 28 will be Since it is shorter than the protrusion stroke of the side locking plate 29, the previous empty case A _c1 is carried out from the conveyor 12 by the belt-driven rollers 12a without any problem.

In addition, small belt conveyors 35 are provided at the tips of the belt conveyors 14 on both sides and the roller conveyor 12 in the center via the stopper 19 or interlocking stopper 20, and in front of each belt conveyor 35, as shown in FIG. As shown, there are transport receiving plates 36 as transport receiving bodies that support the empty cases A _s on both sides, and stepped receivers that support the central empty case A _c at a slightly higher level than the transport receiving plates 36 on both sides. A stepped receiving plate 37 is provided.

Furthermore, as shown in FIG. 3, an endless chain frame 38 is provided on both sides of the receiving plates 36 and 37 from the three belt conveyors 35 to the entire receiving plates 36 and 37.
is arranged on the upper side, and the chain frame 38 on both sides of this
An endless chain 40 is wound around the sprocket foil 39 along the sprocket wheel 39, and a plurality of push shear bars 41 for pushing the three empty cases A _s and A _c are strung at a constant pitch around the chain 40 on both sides. Handle it over and install it. In the center of this push shear bar 41,
As shown in FIG. 5, a rotating body 42 is provided as a convex portion that positions the central empty case A _c slightly forward of the empty cases A _s on both sides. Furthermore, a chain drive roller conveyor 43 is provided at the tip of the conveyance receiving plates 36 on both sides and the stepped receiving plate 37 in the center, and as shown in FIGS. The above roller conveyor 43 from the side

will be established. The guide 45 on one side has a parallel portion cut out.

Further, as shown in FIGS. 2 and 3, a stopper 46 is provided at the end of the roller conveyor 43, and an unloading roller conveyor 47 is provided parallel to one side of the roller conveyor 43, and both rollers Motor 48 between conveyors 43 and 47
A rotating shaft 49 is provided, which is rotated by a rotating shaft 49, and a reversing arm 50 is provided protruding from the rotating shaft 49 in a cross shape.
This arm 50 is inserted between the rollers of the conveyors 43 and 47.

Next, the operation of this embodiment will be explained.

First, empty cases are placed on belt-driven roller conveyor 1.
Bring in two rows of A _s and A _c and lock them with stopper 3.

Next, when the stopper 3 is released, the connected empty cases A _s and A _c are separated and sent to the front of the belt-driven roller conveyor 2 due to the speed difference between the belt-driven roller conveyors 1 and 2 . In this way, three empty cases A _s and A _c per row are carried onto the three converters 4 and 5, respectively, and are stopped by the fixed stopper 7 and the movable stopper 6, respectively.

Next, empty cases A _s on these three converters 4 and 5,
A _c is transferred from this roller conveyor 9 to the chain conveyor 8 by the descent of the roller conveyor 9,
This chain conveyor 8 carries out the product laterally.

Next, on the lines on both sides, the empty cases A _s sent upward from the converter 4 to the chain conveyor 13 are overturned forward one by one by the reversing machine 17, and then Empty cases A _s are turned around so that the openings face inside the line by stopping only the opposite sides by turn stops 18 on the belt conveyor 14, and are stopped by stoppers 19.

Parallel to that, in the middle line, the empty case
A _c is conveyed on the roller conveyor 12 while facing upward and is locked by the downstream side locking body 29 of the interlocking stopper 20 .

Next, when the stopper 19 on both sides and the downstream locking body 29 of the interlocking stopper 20 are retracted downward at the same timing as the push shear bar 41 supported by the endless chains 40 on both sides, this stopper 1
With the release of 9 and 20, the three empty cases A _s and A _c are sent to the belt conveyor 35, respectively, and by these drives, the empty cases A _s and A _c are sent to the front of the belt conveyor 35, and the empty cases A _s , A _c is brought into contact with the push shear bar 41. At this time, as shown in FIG. 5, the central empty case A _c is moved ahead of the empty cases A _s on both sides by a distance slightly larger than the thickness t ₁ of the side plates of the empty cases A _s on both sides by the rotating body 42, and As shown in FIG. 6, the stepped receiving plate 37
Therefore, the empty case A _s on both sides floats above the empty case A _s on both sides by a distance slightly larger than the thickness t ₂ of the lower side plate.

Next, the push shear bar 41 is rotated, and the push shear bar 41 moves the three cases A _s and A _c
When the rear end surface of the A s is pressed, the empty case A _s on both sides is
While being carried onto the receiving plate 36, it gradually moves toward the center along the guides 44 and 45 on both sides, and is fitted into the left and right sides of the central empty case A _c .

Further, when the push shear bar 41 is avoided upward, the chain drive roller conveyor 43
The distance between the empty cases A _s on both sides (the receiving plate 3
6, the width cannot be made smaller than the width of the rotating body 42. ) is narrowed, and finally the open end surfaces of the empty case A _s on both sides come into contact with each other. In this way 3
The empty cases A _s and A _c are combined.

Next, when this combined object is transferred from the roller conveyor 43 to the roller conveyor 47 by the reversing arm 50, the combined object is overturned by 90 degrees, and both sides of the case A _c in the center, which were previously located on the left and right sides, are The case of A _s
position them up and down. This makes it difficult to disassemble the three cases.

Note that the push shear bar 41 has a receiving plate 36,
37 and return to the original position.

〔Effect of the invention〕
