The flowchart of each operation program is as shown in FIG. 5, and the operation of this embodiment will be explained below while explaining the 70-chart.

When the article 1 is sent by the conveyor device 2, it passes through the detection area of the article recognition detector 3. During this passage, the article recognition detector 3 recognizes the shape of the article 1 and the characters and patterns appearing on the surface of the article 1 as patterns. Control the recognition result It MM&
Output to 49. Upon receiving this output, the control program (b) determines that the recognition information has been input in step (1), and executes the next step (2). In step (2), it is determined in which inclined chute 4 the sent cargo 1 should be stored based on the recognition information, and the feeding speed of the conveyor device 2 is determined to take the time required for the cargo 1 to arrive in front of the inclined chute 4. The switching valve 7 and the bifurcated conveyor device 1 should be determined based on the relationship between
0 along with the index time. Based on the designated information, timer settings for n controllers are executed in step (3). At the time set by the timer, the cargo 1 is sent by a conveyor 2 to a place in front of the inclined chute 4 where it is stored. Here, the control subtraction 'J!' is applied to the switching valve 7 specified in step 7 (4). ! , 49 output an opening operation signal via the computer 51, and in the next step (5), a start signal is similarly output to the motor of the specified bifurcated conveyor device 10.

When the pressure from the air pressure source 5 is fed from a designated switching valve 7 to the piston/cylinder arrangement 9, the cylinder rond of the piston/cylinder arrangement 9 is pushed out by the feeding pressure. Therefore, the load 1 is pushed by the push plate 8 and transferred from the conveyor device 2 to the bifurcated conveyor device ff!+101
Move to. Bifurcated conveyor device] When one load is transferred onto O,
The load 1 is sent to the rotary blade 11 side by a conveyor device 10. When the load 1 sent by the conveyor device l'ii' 10 is positioned on the rotary blade 11, the load 1 blocks the detection light beam 21 of each photoelectric detection device, so the detection operation of the photoelectric detection device Sae is activated. Ru. The detection signal for each photoelectric detection device is determined by the computer 5.
1 to the control computer 49, and in step (6) it is determined that the photoelectric detection device has caused a detection operation, and in step (7) the control computer 49 inputs the information to the computer 51. A stop command signal is sent to the motor via
At the same time, a start signal is output to the motor 5. Therefore, the load 1 stops at the upper blade of the rotor blade 11, and the rotor blade 11 begins to rotate by the motor δ. Every time the computer 51 receives a signal from the detector, the number of stored loads in the designated inclined chute 4 is counted up by +1 from the current number of stored loads, and updated and stored in the data memory 46. As the rotary blade 11 rotates, the load 1 is scooped up from the conveyor device IO by the rotation y41 and sent to the inclined chute 4 side. When the rotor blade 11 rotates to the position facing toward the inclined chute 4,
A detector n detects the rotational position of the simultaneously rotating striker row by an angle corresponding to the rotational angle, and outputs a detection signal. When the rotor blade [1] rotates in this manner, the load 1 slides off the rotating gll and is sent into the inclined chute 4. The load 1 slides down inside the inclined chute 4 and is packed downward. The detection signal from the detector n is input into the control computer 49 via the computer 51. When this happens, based on the input of the detection signal, the control subtractor 49 determines in step (8) that the rotation 'R11 has rotated to the set angle, and in step (9) A stop command is output to the motor 6. Therefore, the motor stops and stands by for feeding the next load 1 to the inclined chute 4.

Next, shipping of the cargo 1 will be explained.

First, when inputting the product type and number Np to be taken out from the setting block 56 into the control computer 49, the program set in the program memory 47 of the computer 51 starts flowing (
B) starts to be executed at each step, first step +8
), the initial conditions of the control device a are set. control i
The 1-layer adhesive 9 determines in which inclined chute 4 the variety is stored based on the information from the set wave interval, and determines the position of the chute.

Run to the determined position! A start command is output from the control computer 49 to the traveling control unit 55 so that the kIR 14 stops, and the traveling device 14 travels on the rail 13. While traveling, the traveling position detector of the traveling device H14 detects the traveling position and continues to control δl辅a49, and when the determined position is detected, a stop command is given to the traveling control unit 55, and the traveling device 14 stops. When the traveling device stops at the indexed position, the controller 49 generates standby information. Information such as standby information and the number of extractions (1) is sent from the control computer 49 side to the computer 51 side, and step (b)
), it is determined whether information for retrieval has been input from the control n4 calculator, and if it has been input, the traveling device 14 stops traveling in front of the target inclined chute 4 in the next step (C). When the standby information is input to the computer 51, the next step (dl) is executed. In the step (dl, the number of takeouts ftN, is calculated from the information of the takeout slot inputted to the computer 51. It is stored and set in the data memory 46. Next, in step (e), the stored quantity M of loads in the inclined chute 4 at the position where the traveling device a14 is stopped is read out from the data memory 46, and in the next step (f) The arithmetic processing unit 45 determines whether Np≦M.If N≦M, it is known that the entire desired number htNp can be taken out from one inclined chute 4.

If N, ≦M in step +f), the automatic picking flow (g) is executed. Automatic picking 70-(g
) consists of each step from step (8) to step σ().

At a step, a start command is output from the computer 51 side to the motor 3o side, and the motor starts rotating. Since the load 1 in the inclined seat 4 is sliding downward due to its own weight, as the motor force rotates and the rotor blade 15 rotates,
Only one load 1 in the inclined chute 4 is scooped up onto the rotary blade 15. As the rotary blades 15 continue to rotate, the scooped-up load 1 is transferred onto the bifurcated conveyor device 16. When the rotary blades 15 rotate until the load 1 is transferred onto the conveyor device 16, the striker rotating at the same time
The detector 37 reacts and the detector a37 outputs a detection signal to the computer 51 side. Upon receiving this output result, the computer 51 determines that the detector 37 has performed the detection operation in step (B), and executes the next step (q).

In step (q, the motor (capital) is transferred from the computer 51.
A stop command is output to the motor side, and a start command is then output to the motor side. Therefore, the rotor 15 stops and the conveyor device 16
is driven, and at the same time, the roller 17 is also rotationally driven. When the load 1 is transferred onto the conveyor device 16, the detection light 1j32 is blocked by the load 1, so the detection device 35 outputs a detection signal to the computer 51 side.

After receiving this output result, the computer 51 (step)
In step 8, it is determined that the detection device has activated the detection operation, and in the next step (step 8), a 2-second timer is set and activated. Within the second 2 seconds, the load 1 is sent to the roller 17 side by the conveyor device 16. , the load 1 is further subjected to a feeding force by the rotation of the rollers 17, and finally the load 1 is thrown into the recovery container 12 from the sliding plate 18.

After that, the computer 51 reads out the number target N written in the data memory 46 by the stesoge (g), and every time the computer 51 receives a detection signal from the detection device, the computer 51 reads out the number N, written in the data memory 46.
Subtract 1 from , and write N, -1 as a new Np into the data memory. In the next step (read the newly written Np in q and determine whether Np is O or not, if N, = 0, combine with Nutesop σ force,
- A stop command is output to the motor 51 to stop the conveyor device 16 and rollers 17. If it is not N, -0, the automatic picking flow (
g) is executed to take the load 1 into the recovery container 18 until N,=0. After all Mp items have been taken in, the process returns to step fb) and waits for the next command from the controller n unit 49, and if the next command is to transport the Mp items collected at shipping port 1, the process returns to step fb). , the collection container 12 is moved to the shipping port by the traveling device 14.

Next, a case where Np≦M is not satisfied in step (f) will be described. In this case, only less than N9 loads 1 are stored in the inclined chute 4 at the position where the traveling device is stopped, which means that N1 loads cannot be taken out. In this case, the number M of loads in the inclined chute 4 at the current position is determined in step (h).

Then, calculate the insufficient number Ap by N,, -M, (c, and set N, = Mp at the same time. Next, step (g
), the automatic picking flow (gl is executed and the load l is taken into the collection storage a12) until Np=M, =o, and then in step (i), the control subtraction machine When this happens, the control tl calculation a49 implements the program (b) to replenish the load 1 into the tilting chute 4, and the refilled load 1 is transferred to the Ap
Only the individual pieces are taken out and added into the collection container 12,
Collection container 1 contains N1 pieces of cargo that you want to take out as a whole.
Collect and take out within 2 hours.

According to this embodiment, the inclined chute is automatically replenished with cargo, and furthermore, the specified quantity is automatically taken out from the inclined chute, making it possible to easily perform the replenishing and unloading operations. Efficiency is high because the work can be carried out continuously by linking the work and extraction work. In particular, each time the computer 51 receives a detection signal from between the detection devices between step (g) and step (q), the computer 51 writes Mp-1 into the data memory 46 as a new M. By adding this, you can always know where the cargo is temporarily stored in the inclined chute.

As described above, according to the present invention, it is possible to mechanically replenish cargo into the tilting chute and store it temporarily, and then mechanically take out the stored cargo from inside the tilting chute. This has the effect of providing equipment that allows a series of storage and retrieval operations to be carried out efficiently.
