According to this aspect, the explosive and the charge are supplied from the supply device to the first system of the delivery system constituting the delivery device, and the explosive and the charge are delivered to the charge hole by the delivery means through the second system. Efficient loading operation can be realized by feeding and loading continuously or simultaneously (once).
Here, the system is provided with a feeder (explosive feeder, fill feeder) specific to the explosive and the fill, and the explosive feeder and the fill feeder are arranged in series along the first line. Alternatively, one supply device may be provided with an explosive supply section and a filler supply section, and the explosive and filler may be supplied to the first system from the single supply device.
For explosives, there are cases where a parent die (including an explosive and a detonator) and an additional die are used, and cases where only an additional die is used. A parent die supply device and an additional die supply device may be provided in series along the first system. Further, in order to cope with the case of loading a plurality of filling dies into the charge hole, a plurality of filling dies supply devices may be provided in series along the first system.

In addition, it is desirable that the first system, in which explosives and fillers are continuously supplied and which feeds the supplied explosives, etc. to the second system, has linearity, so the first system is relatively rigid. It is preferably formed by a pipe. On the other hand, the second system, which delivers explosives, etc. supplied from the first system to the charge hole, has a length corresponding to the distance to the charge hole provided in the face, making it easy for workers to handle. Since it is preferable to have a certain degree of rigidity and ensure linearity as in the first system, it is preferably formed by a combination of a hose and a pipe.

For example, the design weight of each load P is displayed on a display device that constitutes the input/output IF 45 . Further, among the charging holes H in the face K stored in the control device 40, the charging hole H into which the object to be charged P is to be loaded is displayed on the display device.

As shown in FIG. 6, the control device 40 performs various functions of at least a communication section 402, a feeding device driving section 404, a delivery device driving section 406, a weight determination section 408, and a storage section 410 by executing a program by the CPU 41. offer. At least part of the processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), etc. Similarly, at least a part of the processing functions may be provided by an FPGA (Field-Programmable Gate Array), a dedicated LSI (large scale integration) such as a numerical processor, an image processor, or other digital circuits.

The communication unit 402 is communicatively connected to the communication IF provided in each supply device 20, the first force-feeder 35, the second force-feeder 36, the control valve 34, and the weighing scale 38 via a network.

The storage unit 410 stores the design weight data of each charged material P (the parent die E1, the additional die E2, and the loaded material C) to be loaded into one charging hole H. As shown in FIG.

The number of explosives E to be loaded into one charge hole H, the number (weight) of fillings C, and the specifications of these manufacturers differ from one construction site to another. If the explosives E, etc. are not supplied to the first system 32 due to the When an explosive or the like is supplied to the first system 32, it is important to prevent the supply of a charge P different from the design specifications to the first system 32.

First, as shown in FIG. 7, a drive command signal S0 is transmitted from the supply device driving section 404 of the control device 40 to the supply mechanisms 22 (the actuators 27 constituting the supply devices 20A to 20D) of the supply devices 20A to 20D. The material to be charged P is supplied to the first system 32 from the supply devices 20A to 20D.

Then, the weight of the material to be loaded P supplied to the first system 32 from each supply device 20A to 20D is measured by the weight scale 38 unique to each supply device 20A to 20D, and the measurement data S1 is obtained from each weight scale 38. It is transmitted to the communication unit 402 of the control device 40 .

The weight determination unit 408 of the control device 40 collates the design weight data regarding each load P stored in the storage unit 410 with the measurement data S1 of each weighing scale 38 received by the communication unit 402, and determines that both are the same. If they do not match, the worker or manager is informed that the weight of the load P does not match the design weight by, for example, a buzzer or a lighting display.

As described above, the step of supplying the designed weight of the explosive E and the charge C from the supply devices 20A to 20D to the delivery system 31 (the first system 32 thereof) constituting the delivery device 30 is the A process of the explosive loading method. becomes.

When it is confirmed that the weight of each material to be loaded P supplied to the first system 32 is the design weight, as shown in FIG. A command signal S2 is transmitted. The first pressure feeder 35 that has received the drive command signal S2 supplies pressure air to the first system 32, and the supplied pressure air causes the main die E1, the two additional dies E2, and the filling C to move in series. , from the first system 32 through the check valve 34 to the middle position of the loading pipe 33a of the second system 33 in the Y5 direction.

In this feeding, in synchronization with the driving of the first pressure feeder 35, a stopper 36b is automatically protruded in the Y10 direction at a midway position of the loading pipe 33a (predetermined position for stopping the parent die E1, etc.), and pressure feed air is The parent die E1 and the like sent out by the motor can be stopped at a predetermined position. It should be noted that this stop control is only an example. The pressure-feeding force and pressure-feeding time of the pressurized air by the machine 35 may be set.

When the parent die E1 and the like are stopped at a predetermined position in the second system 33, as shown in FIG. The drive command signal S3 is transmitted, and the control valve 34 receiving the drive command signal S3 is completely closed.

Next, a drive command signal S4 is transmitted from the delivery device drive unit 406 of the control device 40 to open the control valve 36a in the flow path connecting the second pressure feeder 36 and the second system 33. , a drive command signal S5 is transmitted from the delivery device drive unit 406 to the second pressure feeder 36 .

The second pumping machine 36 that has received the drive command signal S5 supplies pressure air, and the pressure air stops at a predetermined position while sending lubricating water supplied from the water tank 37 in the Y6 direction to the second system 33. The main die E1, the additional die E2, and the filling material C are pushed from the rear in the Y7 direction, and the main die E1 and the like are continuously sent out from the second system 33 to the charging hole H of the face K in the Y8 direction to be loaded. Load the object P.

As described above, the step of continuously moving the explosive E and the charge C through the second system 33 constituting the delivery system 31 and sequentially loading them into the charging hole H is the B step of the explosive loading method.

By using the face piercing machine 100 equipped with the illustrated explosive loading system 50 and applying the illustrated explosive loading method, workers do not have to perform explosive loading work in close proximity to the face K, which is highly painful. Therefore, in the work of loading the charged material P such as the explosive E into the charge hole H drilled in the face K, the work is highly safe and the work is freed from the difficulty of work. Moreover, since the explosive loading system 50 can continuously or simultaneously load a predetermined amount (predetermined weight) of the explosive E and the charge C into the charging hole H, an efficient loading operation can be realized.

It should be noted that other embodiments may be possible in which other components are combined with the configurations described in the above embodiments, and the present invention is not limited to the configurations shown here. Regarding this point, it is possible to change without departing from the gist of the present invention, and it can be determined appropriately according to the application form. For example, although the illustrated example is a form in which each component is controlled using the explosive loading system 50 mounted on the face boring machine 100, it is a form in which each component is controlled using a remote control (remote control). good too.
