する必要がある。 However, in that case, when estimating the movement of garbage,
It is thought that when the dust is tumbled in the vessel, some of the dust becomes a group and is sucked into the storage tank through the communication pipe by negative pressure. Therefore, if there is still trash left in the vessel in this state, one cycle of dust suction is performed, from the introduction of negative pressure and secondary air into the vessel to suction of a group of garbage into the storage tank. ”
will be repeated again. However, in order to perform this repeat timing appropriately, it is necessary to
It is necessary to detect when the cycle's "dust suction" is completed.

管を介して吸引、輸送されていく。 Therefore, the inventor of the present invention looked at the change in the negative pressure value on the suction side during the "one cycle of dust suction" and found the following. In other words, while the negative pressure in the Betsu cell and the garbage storage tank progresses, the negative pressure value increases, and when the secondary air of the Betsu cell is introduced and the tumbling of garbage begins, the negative pressure value suddenly decreases to below a predetermined value. It settles down to the value of . Then, at some negative pressure value during the descent, a group of dust is sucked and transported through the communication pipe.

>Pa, open the inlet valve Vm in step S9 ,
Immediately after that, the input gate Im is opened (state shown in FIG. 6). As a result, secondary air is introduced from the secondary air introduction pipe Am to the Betsu cell Tm, and tumbling of dust begins, the negative pressure value drops all at once, and a group of dust begins to enter the communication pipe D (Fig. 6). The state of)). When a group of garbage has entered the communication pipe D, the negative pressure value becomes approximately constant, and the group of garbage is sucked and transported to the garbage storage tank 10 via the communication pipe D (states of ~ in Fig. 6). ). Furthermore, when a group of garbage begins to enter the garbage storage tank 10 and the garbage in the communication pipe begins to break off, the negative pressure value begins to decrease, and when the communication pipe D is emptied after transporting the garbage,
The negative pressure value becomes a substantially constant value (states of - in Fig. 6). In this way, "one cycle of dust suction" is performed, from the introduction of negative pressure and secondary air into the vessel Tm to the suction of a group of dust into the storage tank 10.

に延びることになる。 Here, the pattern of the negative pressure value on the suction side during the "one cycle of dust suction" will be explained based on FIG. 7. First, the larger the amount of a group of garbage that is sucked into the garbage storage tank 10 through the communication pipe D and transported, the greater the negative pressure value (negative pressure value that takes a substantially constant value) during transportation becomes (7th solid line group in the figure). This is thought to be because as the amount of dirt in the communication pipe D increases, a negative pressure commensurate with the running resistance of the dirt is required.
Further, it is considered that the time required for a group of garbage to be sucked into and transported to the garbage storage tank 10 via the communication pipe D is approximately determined by the length of the communication pipe D. However, if the amount of garbage in a group increases further and the communication tube D is filled, but the garbage continues to enter the communication tube D from Bethel Tm, as shown by the broken line in Fig. 7, the group of garbage This means that the time required for the waste to be sucked into and transported to the waste storage tank 10 via the communication pipe D will be extended.

After starting, wait for a certain period of time to pass in step S10 . Then, after a certain period of time has elapsed, the negative pressure value P N and the differential values P' N and P' N-1 are taken in at step S 11 , and the rate of change of the differential value |P' N −
Wait until P′ N-1 | exceeds the predetermined rate of change “a”,
When "|P' N -P' N-1 |>a", the process advances to step S13 . Here, the rate of change of the differential value exceeds the predetermined rate of change when (1) the negative pressure value drops suddenly and then becomes a substantially constant negative pressure value (state shown in Fig. 6);

Then, when "P N ≧ Pb", it is determined that "case (1) or (2)" is not the case "(3)" above, and in this case, "1 cycle of dust suction" is still not possible.
Since this is in the middle of the process, the process proceeds to step S14 , where the negative pressure value P N and the differential values P' N and P' N-1 are taken in again, and in step S15 , the rate of change of the differential value |P' N −P' N Wait until -1 | exceeds the predetermined rate of change “a”, and then calculate “|P′ N −P′ N-1
|>a”, proceed to step S16 . Then,
In this step S16 , wait until the negative pressure value P N becomes smaller than the predetermined value Pb, and when "P N <Pb","1 cycle of dust suction" corresponds to the above "case (3)". It is determined that the process (in FIG. 8) has been completed. That is, in step S17 , the input gate Im is closed in preparation for air suction in the next "one cycle of dust suction", and the introduction valve Vm is closed, and then step S8
We will return to ``1 cycle of dust suction'' (shown in Figure 8) again.

る。 In this way, while repeating "one cycle of dust suction", if it is determined in step S13 that "P N <Pb","one cycle of dust suction" is repeated.
Since the negative pressure value P N has become smaller than the predetermined value Pb when the rate of change |P′ N −P′ N-1 | of the differential value exceeds the predetermined change rate “a” for the first time, “1” In the case of ``cycle dust suction'', ``cases (1) and (2)'' do not exist, and suddenly it becomes ``case (3).'' This means that there is no more dust in the Bethel Tm, and in that case, not only has "one cycle of dust suction" (shown in Figure 8) been completed, but also the dust has been sucked out of the Bethel Tm. It is determined that this has been completed, and the process proceeds to step S18 , where the discharge gate Em is closed, the introduction valve Vm is closed, and the process moves on to suction of dust from the next vessel. That is, step
In S19 , determine whether the subscript m is the final number,
If it is not the final number, the process returns to step S3 and the above process is repeated for the next numbered vessel. On the other hand, if it is the final number, the process advances to step S20 , where the suction device 23 is turned off and air suction is stopped.

している。 In the above flow, in steps S3 to S10 , the pressure in the garbage storage tank 10 and the vessel Tm is made negative, and then secondary air is introduced into the vessel Tm, and the garbage in the vessel Tm is transferred to the garbage storage tank through the communication pipe D. A transportation control means 42 is configured to control the suction device 23 and the secondary air introduction means 41 so as to transport the air to the secondary air introduction means 10. Also, steps S 11 to S 20
In response to the output of the negative pressure detection means (pressure sensor) 25, when the rate of change of the negative pressure gradient exceeds a predetermined rate of change and the negative pressure value becomes smaller than a predetermined value, one cycle is performed by the transport control means 42. This constitutes a completion signal output means 43 for outputting a dust suction completion signal.

ることになる。 When collecting rubber, the transportation control means 42 controls the suction device 23 and the secondary air introduction means 41 to make the garbage storage tank 10 and the vessel Tm negative pressure, and then introduces secondary air into the vessel Tm. Since the garbage in Tm is tumbled and transported to the garbage storage tank 10 via the communication pipe D, the garbage is reliably collected in the garbage storage tank 10.

行われる。 In that case, based on the negative pressure value detected by the negative pressure detection means (pressure sensor) 25, the completion signal output means 43 indicates that the rate of change in the negative pressure gradient exceeds the predetermined rate of change and the negative pressure value is lower than the predetermined value. Since it is determined that one cycle of dust suction has been completed when the dust has become smaller, it is possible to accurately detect when one cycle of dust suction has been completed, and when repeating one cycle of dust suction again, the repetition timing can be determined. Done properly.
