Abstract

PURPOSE:To miniaturize an internal device of a warehouse by placing the first transmitting device inside the warehouse and the second and the third transmitting devices outside in series, and forming the third device to be able to be driven and stopped by passing of loads to be stocked and shipped through a fixed position, in the case of a device for transmitting drum cans and the like into and out of the warehouse. CONSTITUTION:Detection signals of position detectors PD1-PD7, and signals of position detector 35 of a crane grabbing apparatus 34 and fully open position detector 36 of a door 2 are input to a sequential controller system 33. The sequential controller system 33 makes sequential control on each of roller conveyor C1-C3 and the door 2 according to a fixed program. In particular, if the detector PD1 is operated by a drum can D when it is stocked, the sequential controller system 33 stops a motor M2 and subsequently third roller conveyor C3. On the contrary, operation of detector PD1 in reverse direction drives the motor M2 and the third conveyor C3. An internal transfer device of a warehouse is miniaturized and spacial efficiency can be improved by this system.

Motor M1 for driving C2 and C3. The motor M2 and the door 2 opening/closing motor M3 are controlled to start and stop.

Next, the operation of the loading/unloading device configured as described above will be explained.

The warehousing operation will be explained based on flow chart 1 to (flow chart) shown in FIG.
After arranging them on the 0-lar conveyor C3 using a forklift or by hand, operation is started manually. When the operation starts, as shown in step S1, the sequence control a
m tN 33 is for each motor M1. M,! Start. As a result, the motor M+ causes the 20th lar conveyor C2 and the 10th lar conveyor C1 to move together from the 20th lar conveyor C2 side to the 10th lar conveyor C1 side via the drive transmission means 23. The third
The 0-lar conveyor C3 transports the articles to the 20th-lar conveyor C.
It is driven to transport to the second side. Therefore, the drums on the 30th-largest conveyor C3 are transferred to the warehouse A side, contact the detection roller 29 of the 6th-place detector PD6, and push down the i2 output roller 29. At this time, in
k''A output roller 29 descends while resisting the pressure of the spring 31, and the support rod 30 moves toward the support tube 28, IIi
Since the detection roller 29 descends while being guided by the through holes 27a and 26a, it sinks smoothly from the conveyance path and does not become an obstacle to the conveyance of the drum.

Then, as the detection roller 29 descends, the on (detection) signal of the sixth position detector PDa is transmitted to the sequence control mechanism 3.

Based on this ON signal, each motor M+, M2,
Since no command signal is output to M3, the drum that has reached the position of the sixth position detector PDs is conveyed in that state beyond the position of the sixth position detector PD6.

Next, when the drum comes into contact with the two detection rollers of the first position detector PD+, the 20th roller conveyor C2
When reaching the end on the 30th-ra conveyor C3 side, the detection signal of the first position detector PC)+ is input to the sequence control mechanism 33, as in the case of the sixth position detector PD6 of the cruise speed. However, the sequence control mechanism 33 does not output a signal to each motor M+, M2, and M3 based on this detection signal, so the drum can remains unchanged until the first purchase detection j! :'l p D + is transported beyond the position.

Subsequently, when the drum presses down the two detection rollers of the second position detector PD2 and the detection signal of the second position detector PD2 is input to the sequence control mechanism 33 (see step S2), the sequence control ( The Ikuyoko 33 stops the motor M2 as shown in step S3.
Since the operation of the 30th lar conveyor C3 is stopped, the transport of drums on the 30th lar conveyor C3 is stopped, and only one drum ID on the 20th lar conveyor C2 is transported to the warehouse A side. be done. As a result, even if the third [

Further, when the drum truck moves on the 10th larcon f\a C1 and passes the fourth position detector PDJ, a detection signal is sent from the fourth position detector PD, + to the sequence control mechanism 3.
However, the sequence control mechanism 33 does not output command No. 19 to each motor M+, M2, and lVh. Then, the drum can on the 10th lar conveyor C1 pushes down the detection roller 29 of the 5th position detector PDs (at the bottom of the 10th lar conveyor C1), and the fifth position detector PDs When the detection signal is input to the sequence control side 33 (see step 814), the sequence control 11 isogaku 33 starts the motor M3 for a predetermined period of time and closes the door 2, as shown in step 311.

Note that the process of starting motor M3 and closing door 2 is as follows:
The sequence 111j may be controlled based on the ON signal of the fourth position detector PD40. For example, when the fourth position detector PDJ turns from ON to OFF, the sequence 111j is controlled when the groove 33 is
g to start or when the drum is at door 2.
If there is no contact with rL, then when the fourth position detector PDJ turns on, a command to close door 2 (motor M3 start command) is issued.
It may also be possible to output .

Further, the sequence control mechanism 33 closes the door 2 and stops the motor lVl+ as shown in step 312, thereby stopping the 10th color conveyor C1. Next, as shown in step 313, the crane gripping device 34 is lowered, and the crane gripping device 34 grips and raises the drum that has reached the curved end of the 10th-larger conveyor C1 (see step 814). . When the crane gripping device 34 reaches the upper limit position and the detection signal of the upper limit position detector 35 is input to the sequence control I i +R33 (see step 814), the lifting of the crane gripping device 34 is stopped and the drum truck is moved. While horizontally moving and transporting the drums to the predetermined position 2 (see step S16), the sequence control 1 mechanism 33 determines whether all the drums have been carried into the warehouse A, as shown in step 17 (step S16). (See S17). If the delivery of the drums has been completed, the process is terminated and the person in charge Q manually assists the association, while if the delivery of the drums has not been completed, the process returns to step S1 and each Motor 1v'h.

- 12 is activated, and the processes of steps 82 to 316 are repeated.

In addition, the sequence control n structure 33 is the crane gripping device 3.
When the ON signal of the upper limit position detector 35 of No. 4 is
The motors fVI+ and Mz are set up, but in order to save time, the drum pressure is gripped by the crane gripping device 34 and the 10th roller conveyor C1
If it is removed from the top (that is, when the fifth position detector PD5 turns from on to off) and all the drums have not been presented, motors M+ and M2 are turned off. It may also be started. In addition, the number of storage units for drums CE is counted by sequence system 'QD machine + A 33 to 81, and when the pre-registered number is reached, αl'l is automatically set to J)? It may also be stopped.

Next, the unloading operation will be explained based on the flowchart shown in FIG. When the drum is placed on the conveyor C1, the detection signal of the fifth position detector PDs is input to the sequence control mechanism 33 (see step 820), so the crane gripping device 34 controls the drum f as shown in step S21.

The system 33 starts and stops the motor M3 to fully open the door 2 as shown in step S61.

Subsequently, when the drum on the 20th rack conveyor C2 reaches above the first position detector D1, the first position detector PD+ inputs a detection signal to the sequence system i11 mechanism 33 (step S62). ), the sequence control mechanism 33 receives this signal as 1. t, the motor M2 is then started to operate the 30th color conveyor C3 (see step S63). Therefore, the drum can is the 20th-
Get on the 30th-large conveyor C3 from the large conveyor C2 (there are many).

The 1-ram canister is connected to the sixth position detector PD.
When the detection roller 29 of s is pushed down and the first position detector PDe or one detected word is input to the sequence system 12i1 mechanism 33 (see step S64), the sequence control mechanism 33 starts the motor as shown in step 365. M+
, M2 are stopped, and the first to 30th conveyors C1,
Stop C2 and C3.

Therefore, the drum car stops at the position defined by the first position detector PD6. Then, step 852
The process returns to step 853 to repeat steps 853 to S65 for unloading the next drum.

In this way, the drums END are lined up at a predetermined interval on the 30th-lar conveyor C3, and when the most advanced drum reaches above the first position detector PD, all controls are stopped. be done.

In the second embodiment, instead of providing the 40th lar conveyor C4, the 10th lar conveyor C1 may be made longer. J5 again. As shown in FIG. 12, the first to ninth position detection pins PD+ to PD9 used in each of the above embodiments 1ζ1 are rotated by the support frame 41 instead of the fixed detection roller 29 shown in FIG. Using the detection Kawaguchi-ra-42 provided at eye H, in this case, 1
~Ram ir; When the object to be conveyed M presses against the detection roller 42, the detection roller ll2 rotates and lowers, so that the object to be conveyed moves more smoothly.
There is less possibility that the position detector becomes an obstacle to the conveyed object, and the lowering of the detection roller 42 (t) 81 is carried out smoothly, so that the detection is carried out reliably. Alternatively, an air curtain may be used instead of the automatic door 2. Part 1
9th, 3rd. The fourth position detection 7; PD3°PD4, motor Mq, and all Jul In neck detection '-336'* become unnecessary.

Also, instead of the first position detector PD6, the first position detector PD+
After a predetermined period of time after receiving the detection signal of
VI2 may be floated to reduce the distance between the conveyed objects on the roller conveyor C3 at the time of leaving the warehouse. Furthermore, it goes without saying that another conveyor such as a belt may be used instead of the roller conveyor, and another sensor such as a phototube may be used instead of the position detector.

As explained above, the present invention provides a third
The yQ feed is carried out from (14 to
Since this is a system designed to stop the second transport mechanism (Ill), even if there are multiple objects to be transported irregularly arranged on the 311a transport mechanism, there will be no folding on the second transport mechanism. Only one item to be transported can be loaded and separated from other items to be transported, and transported separately to the ink pad. Therefore, it can be transported within the warehouse.

Sorting allows the device to be made smaller and improves the space utilization efficiency within the storage. Furthermore, when leaving the warehouse, the first position detector detects the transported objects that have been transported one by one from the first transporting side to the second transporting side, and the transported objects are While being transported a predetermined distance on the conveyance groove, the 3rd W1 feed ■
Since the mechanism is designed to be moved υJ, the distance between the objects to be transported on the third transport mechanism can be reduced, and the work of taking out the objects to be transported by a forklift or the like can be easily performed. Furthermore, since the first WI transport mechanism and the second transport mechanism are linked by the drive transmission means, the drive device can be saved, and in this case, the part that constantly passes through the inside and outside of the warehouse is driven by the drive transmission means. The heat transfer through this penetrating portion is small and can be ignored.
