DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hopper for receiving grains supplied by a supplier, discharging means for discharging the grains received by the hopper, and supplying the grains discharged from the discharging means to a grain processing unit. And a control means for switching the discharge means between a discharge state and a discharge prohibition state.

[0002]

2. Description of the Related Art Conventionally, in such a receiving section,
As the supplier puts the grain into the hopper, the discharging means is switched to the discharging state by manual operation (for example, operation by the supplier), and the grain received by the hopper is discharged to the feeding means. And a supply grain detection means for detecting the presence or absence of the supply grain supplied by the supply means, wherein the supply grain detection means detects a state where there is no supply grain supplied by the supply means. The control means is configured to automatically switch the discharge means to the discharge prohibition state based on this.

[0003]

In such a conventional apparatus, since the switching of the discharging means to the discharging state is performed manually, there is a problem that the operation is not only complicated but also may be forgotten. there were.

[0004] In addition, the feeding of grain to the hopper may not always be continuous but may be in an intermittent state. In such a case, the state in which the grain supplied by the feeding means is temporarily interrupted may occur. As a result, the supplied grain detection means detects the absence of the supplied grain, so that the control means erroneously switches the discharge means to the discharge prohibited state even though the supplier has not yet input the grain. there were.

[0005] The present invention has been made in view of such circumstances, and an object of the present invention is to solve the above-mentioned problems at once.

[0006]

According to a first feature of the present invention, there is provided a grain processing facility comprising: a receiving grain detecting means for detecting the presence or absence of a grain received by the hopper; Supply grain detection means for detecting the presence or absence of supply grain to be supplied is provided, and the control means switches the discharge means to a discharge state based on the reception grain detection means detecting a state with the reception grain. The receiving grain detecting means detects the absence of the receiving grain and the supplied grain detecting means detects the absence of the supplying grain, and switches the discharging means to the discharging prohibited state. The point is that it is configured as follows.

[0007] A second characteristic configuration is that command means is provided for instructing completion of charging of the cereal into the hopper based on a command from a supplier, and the control means determines that the received cereal detecting means has no received cereal. The state is detected, and the supplied grain detecting means is configured to switch the discharging means to a discharge prohibiting state after a lapse of a set waiting time after detecting the state where there is no supplied grain, and the feeding from the command means is performed. The point is that the setting wait time is configured to be shorter when there is a completion command than when there is no input completion command.

[0008]

According to the first characteristic configuration, the control means is automatically controlled based on the fact that the receiving grain detecting means detects the state of the receiving grain as the supplier starts to feed the grain into the hopper. Since the discharging means is switched to the discharging state, the grains received by the hopper are automatically discharged to the supplying means. Also, with the completion of grain input into the hopper of the supplier,
Based on the receiving grain detecting means detecting the state without the receiving grain and the supplying grain detecting means detecting the state without the supplying grain, the control means switches the discharging means to the discharging prohibited state.

According to the second characteristic configuration, when there is no input completion command from the command means, the control means detects that the receiving grain detecting means has no receiving grain and the supplied grain detecting means determines whether or not the supplied grain is detected. When a predetermined waiting time elapses after detecting the absence state, it is determined that the charging has been completed, the discharging means is switched to the discharge prohibiting state, and when there is a charging completion command from the command means, the control is performed. The means switches the discharge means to a discharge prohibited state after a lapse of a set waiting time shorter than when there is no input completion command.

[0010] When the input of the grain is intermittent, the receiving grain detecting means and the supplied grain detecting means simultaneously detect the section where the grain input is interrupted, and set the discharging means to the discharging prohibited state. The predetermined set waiting time is set in consideration of a time in which the state in which the grain is interrupted is expected to be continued when the grain is in an intermittent state so as not to switch.

[0011]

According to the first characteristic configuration, the discharging means is automatically switched to the discharging state, so that the manual operation conventionally performed becomes unnecessary, the work efficiency can be improved, and the operation is forgotten. The problem that there is a danger can be surely solved.

[0012] In addition, when the receiving grain detecting means detects a state where there is no receiving grain and the supplied grain detecting means detects a state where there is no feeding grain, the discharging means is switched to a discharge prohibiting state. Even if the input is intermittent, while any of the receiving cereal detecting means or the supplied cereal detecting means detects the presence of the grain, the discharging means maintains the discharging state and is switched to the discharging prohibited state. When the receiving grain detection means and the supplied grain detection means both detect the absence of grain and the grain input is completed, the discharging means is switched to the discharge prohibited state, so the grain input of the supplier is completed. It is possible to minimize the problem that the discharging unit is erroneously switched to the discharging prohibition state when the discharging is not performed.

[0013] According to the second characteristic configuration, after a lapse of a predetermined set waiting time since the receiving grain detecting means detects a state without the receiving grain and the supplied grain detecting means detects a state without the supplying grain. By switching the discharge means to the discharge prohibition state, even if the receiving grain detection means and the supply grain detection means are simultaneously in a state of detecting no grain,
When the continuation time of the detection state is within the predetermined set waiting time, that is, when the input of the cereal is merely an intermittent state, the switching of the discharging means to the discharge inhibition state is prevented, and the detection state is stopped. When the continuation time exceeds the predetermined set waiting time, that is, only when the cereal feeding is completed, the discharging means is switched to the discharge prohibiting state. Erroneous switching of the means to the discharge prohibition state can be reliably eliminated.

Further, even if the erroneous switching is surely eliminated by switching the discharge means to the discharge prohibition state after the elapse of the predetermined set waiting time, when the completion of the charging is clear, that is, when the delivery is completed, When the completion of charging is instructed, the delay of the control can be minimized by switching the discharger to the discharge prohibition state after a lapse of the set waiting time shorter than the predetermined set waiting time.
