A carry-out conveyor 19 carries empty bottles 11 to the bottling process for contents such as medicines and foods, and a bottle ( The carry-in conveyor 21 that carries the filled bottles (hereinafter referred to as filling bottles) 20 to the transshipment conveyor 13 side is such that the carrying direction thereof is the same as the carrying direction of the transshipment conveyor 13, as shown by the arrow in FIG. The carry-in end of the carry-in conveyor 19 is adjacent to the unloading position of the transshipment conveyor 13, and the discharge end of the carry-in conveyor 21 is adjacent to the loading position of the transshipment conveyor 13. They are adjacent to each other. Further, a standby position is set on this carry-in conveyor 21, where the filled bottles 20 are stopped for a certain period of time on the carry-in conveyor 21, and the filled bottles 20 that have reached this standby position are contacted and prevented from being transported. A positioning stopper 2 for stopping the filling bottle 20 at a standby position.
2 is provided on the carry-in conveyor 21,
A phototube may be used as a means for stopping the filling bottle 20 at the standby position, and the operation of the carry-in conveyor 21 may be stopped at the same time the filling bottle 20 reaches the standby position.

On the other hand, a pair of guide rods 23 are installed above the transshipment conveyor 13, the carry-out conveyor 19, and the carry-in conveyor 21, and extend parallel to the conveyance direction of the carry-out conveyor 19 and the carry-in conveyor 21. A transfer arm 25 that interconnects the pair of sliders 24 that is slidably fitted to the guide rod 23 is fixed in a state that straddles the carry-out conveyor 19 and the carry-in conveyor 21. has been done. On this transfer arm 25 above the transfer conveyor 19, a fluid pressure cylinder 26 for lifting and lowering empty bottles is vertically protruded and is provided with a piston rod (not shown) that projects downward from the transfer arm 25. At the tip, there is a suction cup 2 as a support member that grips the empty bottle 11 on the lower end surface.
An empty bottle multi-mounting board 28 is fixed, in which empty bottles 7 are attached in correspondence with the number and spacing of the empty bottles 11 stored in the bottle storage box 12. Correspondingly, a fluid pressure cylinder 29 for lifting and lowering filled bottles, which is provided with a piston rod (not shown) that projects downward from the transfer arm 25, vertically projects from the transfer arm 25 above the carry-in conveyor 21. A filled bottle transfer plate 31 having the same structure as the empty bottle transfer plate 28 is fixed to the tip of the piston rod, and a suction cup 30 as a support member for holding the filled bottle 20 is attached to the lower end surface. has been done. The tips of piston rods 33 of a pair of transfer hydraulic cylinders 32 that reciprocate along the guide rod 23 together with the transfer arm 25 are fixed to the slider 24, and the transfer hydraulic cylinders 32 piston rod 33
The unloading position and the loading position of the reloading conveyor 13 correspond to the empty bottle transfer plate 28 and the filled bottle transfer plate 31 at one reciprocating end, respectively, and the filled bottles at the other reciprocating end correspond to the empty bottle transfer plate 28 and the filled bottle transfer plate 31, respectively. The standby position of the carry-in conveyor 21 corresponds directly below the transfer plate 31.

Next, to describe the operation of the above-mentioned device, when the bottle storage box 12 with the folded lid 14 opened so that the bottom of the empty bottle 11 is facing up is conveyed on the transshipment conveyor 13, first it is transferred to the transshipment conveyor 13. It comes into contact with the extraction stopper 15 protruding above the transfer conveyor 13 and comes to a halt at the extraction position, but at this time, above the extraction position, which is one reciprocating end of the piston rod 33 of the transfer fluid pressure cylinder 32. The fluid pressure cylinder 26 for lifting and lowering empty bottles on the empty bottle transfer plate 28 which has reached
is activated to lower the empty bottle transfer plate 28, and after the empty bottle 11 is sucked by the suction cup 27 at the lower end, the empty bottle transfer plate 28 is raised again and the bottle storage box 12 is lifted.
Pull up the empty bottle 11 from.

When the empty bottle transfer plate 28 reaches its rising end, the piston rod 33 of the transfer hydraulic cylinder 32 expands and moves the empty bottle transfer plate 28 above the unloading conveyor 19, and the other piston rod 33 Stops at the reciprocating end of. At this time, directly below the filled bottle transfer plate 31, the filled bottle 20 filled with the contents in the bottling process is conveyed to the standby position by the carry-in conveyor 21, and is stopped when it comes into contact with the positioning stopper 22. It has become a state.

When the piston rod 33 of the transfer fluid pressure cylinder 32 reaches the other reciprocating end, the empty bottle lifting fluid pressure cylinder 26 operates again to move the empty bottle transfer plate 2
8 is lowered, and the suction force of the suction cup 27 is released at the lowering end, so that the empty bottle 11 is transferred to the conveyor 1 for carrying out.
The empty bottle 11 is carried out to the bottling process side by the operation of the carry-out conveyor 19, and only the empty bottle transfer plate 28 is raised to its original position again. On the other hand, the filled bottle transfer plate 31 is lowered by the fluid pressure cylinder 29 for lifting and lowering filled bottles, which operates at the same time as the hydraulic cylinder 26 for lifting empty bottles, and is fixed on the conveyor 21 for carrying in by the suction cup 30 at the lowering end. After contacting the positioning stopper 22 and adsorbing the filled bottle 20 waiting at the standby position, the filled bottle transfer plate 31 rises again to pull up the filled bottle 20 from above the carry-in conveyor 21. In addition, since the filled bottles 20 filled with contents are carried one after another at regular intervals from the bottling process side on the carrying conveyor 21, the filled bottle transfer plate 31 moves again above the standby position. In the meantime, the next filling bottle 20 is stopped at the standby position.

Meanwhile, during this time, the extraction stopper 15 and the loading stopper 16 rotate 90 degrees to start conveying the empty bottle storage box 12 that had been stopped at the extraction position, and the empty bottle storage box 12 moves to the extraction stopper 16.
After a certain period of time, the unloading stopper 15 and the loading stopper 16 are rotated 90 degrees in the opposite direction and protrude above the reloading conveyor 13. 16 and stops at the loading position, and at the same time, the new bottle storage box 12 containing the empty bottle 11 comes into contact with the extraction stopper 15 and stops at the extraction position.

When the empty bottle transfer plate 28 and the filled bottle transfer plate 31 reach their rising ends, the transfer fluid pressure cylinder 32 is operated again to pull the piston rod 33 back to one reciprocating end, and the empty bottle transfer is completed. The mounting plate 28 and the filled bottle transfer plate 31 with suspended filled bottles 20 are placed above the bottle storage box 12 containing empty bottles 11 at the unloading position waiting on the reloading conveyor 13 and at the loading position, respectively. Move above the empty bottle storage box 12. Thereafter, the fluid pressure cylinder 26 for lifting and lowering empty bottles and the fluid pressure cylinder 29 for lifting and lowering filled bottles are operated, and the empty bottle transfer plate 28 moves the empty bottles 11 from the bottle storage box 12.
This operation is the same as the one described above, so its explanation will be omitted. on the other hand,
The filling bottle transfer plate 31 supporting the filling bottle 20 descends to release the suction force of the suction cup 30 at the lower end, so the filling bottle 20 is waiting at the loading position on the reloading conveyor 13. The bottle is placed in the empty bottle storage box 12, and only the filled bottle transfer plate 31 is raised.

Thereafter, the above-described procedure is repeated, and the filled bottles 20 are transferred into the bottle storage box 12 in which the empty bottles 11 are stored.

As described above, according to the container transshipment device of the present invention, empty containers can be taken out from the container storage box on one transshipment conveyor, and containers filled with contents can be automatically transshipped. Moreover, since the container storage box can be accurately positioned and stopped, there is no need for a temporary storage space for empty containers or the work required to transport them, which is required in the past, making it possible to downsize the device and reduce equipment costs. It is possible.
