Abstract

PROBLEM TO BE SOLVED: To mount a load onto a load mounting shelf of a moving body without needing large driving force and advanced synchronous control for a driving motor of a charging conveyor. SOLUTION: Loads delivered from an upper reaches device are stored on a storage part 41 of a charging conveyor 4. One case of load is delivered to a delivery mechanism part 4 at specified timing from the time of detecting a load mounting shelf 3 or a circulating horizontal rotary moving body 2 by a position detecting device 6. In this state, when the load mounting shelf 3 passes through the lower part of the delivery mechanism part 42, a transfer arm 31 provided at the load mounting shelf 3 at specified height pushes out the load on the delivery mechanism part 42 into the moving direction of the load mounting shelf 3. The pushed-out load is transferred onto the load mounting shelf 3 while sliding along an inclined face 46 of a charging part 47.

FIG. 1 is a plan view showing a sorting apparatus according to an embodiment of the present invention. As shown in the figure, the sorting apparatus 1 includes a horizontal rotating moving body 2 that circulates and sorts packages such as packing goods and containers by circulating on a horizontal plane, a plurality of loading shelves 3 attached to the horizontal rotating moving body 2, Loading conveyor 4 and a plurality of payout chutes 5a to 5k for transferring goods to the loading rack 3
Having. As shown in the perspective view of FIG.
It has a transfer arm 31 provided at a constant height on the upstream side in the rotation direction of the horizontal rotary moving body 2. The loading conveyor 4 is provided orthogonal to the moving direction of the horizontal rotary moving body 2, and has a storage unit 41 and a cutting-out mechanism unit 42. The storage unit 41 is formed of, for example, a storage-type conveyor called an accumulator, and is provided on the upstream side of the charging conveyor 4 and stores packages such as packaged goods and containers transported from the upstream apparatus. The cut-out mechanism 42 is provided on the downstream side of the storage unit 41, and has a leading end protruding above the loading rack 3, and cuts out the luggage stored in the storage unit 41 one by one into the loading rack 3. A vertical stopper 44 that moves up and down by the drive cylinder 43 is provided at the boundary with the storage unit 41, and a tip stopper 45 that positions and stops the load is provided at the tip. At a position corresponding to the position of the loading shelf 3 at a side end of the tip of the cutout mechanism 42 in the moving direction of the horizontal rotary moving body 2, there is provided an input section 47 whose upper surface is formed by an inclined surface 46. A position detecting device 6 for detecting the loading shelf 3 moving on the traveling path of the horizontal rotary moving body 2 by a certain distance upstream from the loading conveyor 4 is provided.

As shown in the block diagram of FIG. 3, the position detecting device 6 transmits a rotational position signal to a loading conveyor drive control unit 8 which inputs a speed signal from a moving unit drive control unit 7 which drives and controls the horizontal rotary moving unit 2. Enter The input conveyor drive control unit 8 controls the operations of the storage drive unit 411 that drives the storage unit 41 of the input conveyor 4, the cutout mechanism drive unit 421 that drives the cutout mechanism unit 42, and the drive cylinder 43 that moves up and down the vertical movement stopper 44. It controls the cylinder driving unit 431.

The horizontal rotating moving body 2 configured as described above
The operation of transferring packages, containers, and other packages to the loading rack 3 by the loading conveyor 4 will be described.

For example, the luggage 9 cut out from an upstream device such as an automatic warehouse or a flow rack is transported by a conveyor or the like to the input conveyor 4 of the sorting device 1, and as shown in FIG.
It is stored in the storage unit 41 of the charging conveyor 4. When the luggage 9 is stored in the storage unit 41, as shown in FIG. 2, the vertical movement stopper 44 is raised by the drive cylinder 43 of the cutout mechanism 42, and the accumulated luggage 9 is stored.
Is positioned and stopped. As described above, since the storage unit 41 for stopping and storing the load 9 is constituted by a storage type conveyor called an accumulator, it is not necessary to apply a certain load or more to the stopped load 9. When the position detecting device 6 detects the loading rack 3 of the horizontal rotating moving body 2 circulating in this state, the position detecting device 6 sends a rotation position signal to the input conveyor drive control unit 8. When the input conveyor drive control unit 8 receives the rotation position signal, the loading rack 3 detected by the position detection device 6 reaches the position of the input conveyor 4 based on the speed of the horizontal rotating mobile unit 2 sent from the mobile unit drive control unit 7. The timing is calculated, and the drive timing of the cutout mechanism 42 is calculated from the calculated timing. Thereafter, the input conveyor drive control unit 8 lowers the vertical movement stopper 44 by the cylinder drive unit 431 in accordance with the calculated operation timing, drives the cutout mechanism drive unit 421, and cuts out one case of luggage 9 into the cutout mechanism unit 42. . When the luggage 9 of one case is cut out to the cutout mechanism section 42, the vertical movement stopper 44 is raised again, and the drive of the cutout mechanism drive section 421 is stopped. This cutting mechanism 42
When the luggage 9 of one case is cut out, the cut-out luggage 9 is positioned by the tip stopper 45 of the cutout mechanism 42 and stopped there. Can be positioned. In this state, when the load carrying shelf 3 passes below the cut-out mechanism section 42, the transfer arm 3 provided on the load carrying shelf 3 at a constant height.
1 hits the side surface of the load 9 on the cut-out mechanism 42 and pushes the load 9 in the moving direction of the load rack 3 with the movement of the load rack 3. The pushed-out luggage 9 is placed on the inclined surface 46 of the input section 47.
Is transferred to the loading rack 3 while sliding along. The luggage 9 transferred to the loading rack 3 is conveyed to the payout chutes 5a to 5k by the horizontal rotary moving body 2, and is discharged from a predetermined payout chute and sorted.

The transfer arm 3 provided on the loading rack 3 moving the load 9 cut out to the cutout mechanism 42 in this manner.
Since the transfer is performed to the loading rack 3 in step 1, there is no need to apply a large driving force to the loading conveyor 4 and no advanced synchronization control is required, and the load 9 is reliably transferred to the loading rack 3 with a simple configuration. can do.

In the above-described embodiment, the case in which the luggage 9 is cut out from the storage section 41 to the cut-out mechanism section 42 one by one by the vertical movement stopper 44 which moves up and down by the drive cylinder 43 has been described. You may. Further, the input section 47 having the inclined surface 46 may be constituted by a belt or the like.

[0015]

As described above, the present invention uses the transfer arm attached to the moving loading rack when loading the load from the loading conveyor to the loading rack of the horizontally rotating moving body. The load is transferred from the loading conveyor to the loading rack, so that a large driving force is not required for the drive section of the loading conveyor and sophisticated synchronization control is not required, and a simple configuration ensures reliable operation. Luggage can be loaded onto the loading rack of the horizontally rotating mobile unit. In addition, since excessive force is not applied to the luggage, it is possible to reduce the damage of heavy goods to the product, and it is possible to stably load the luggage.

[0016] Further, since the luggage is loaded into the loading rack by sliding the inclined surface of the loading section of the loading conveyor, it is possible to smoothly transfer even products that are easily overturned without overturning.
