The drive unit 15 and the motor 23 with a speed reducer can be controlled by operating the control button 33 and the touch panel 34.

Next, functions and effects of this embodiment will be described.

In the briquette machine 01, when the drive unit 15 is driven, the rotational driving force of the drive unit 15 is first transmitted to the first roll shaft 13. Since the first gear 29 provided on the first roll shaft 13 and the second gear 30 provided on the second roll shaft 14 are engaged, the rotational driving force of the first roll shaft 13 is the second. It is transmitted to the roll shaft 14 and rotates in opposite directions. In this state, when the motor 23 with a speed reducer is rotated, the rotational force generated from the motor 23 with a speed reducer is transmitted to the feeder screw 19 to rotate the feeder screw 19, and the raw material in the hopper 18 is fed to the feeder. The screw 19 is pushed between the first roll 11 and the second roll 12. And the pocket formed in each outer peripheral surface of the 1st roll 11 and the 2nd roll 12 cooperates, and a briquette is compression-formed by pressurizing and solidifying a raw material.

The hydraulic cylinder 31 is operated by hydraulic oil supplied from the manual hydraulic pump 35. In order to press the movable bearing unit 17 against the cylinder rod 51 in the hydraulic cylinder 31, the following operation is performed. First, as shown in FIG. 6, the manual hydraulic pump 35 and the valve 36 are connected by a hose that is a pipe line 52. Next, the valve 36 is opened, and the lever 37 is manually reciprocated up and down. By the above operation, the hydraulic oil stored in the manual hydraulic pump 35 is sent to the hydraulic cylinder 31 and the cylinder rod 51 moves in the direction toward the movable bearing unit 17. Thereby, the cylinder rod 51 presses the movable bearing unit 17 through the load cell 32. Here, by closing the valve 36, even if the manual hydraulic pump 35 and the hose are removed, the force by which the cylinder rod 51 presses the movable bearing unit 17 by the hydraulic pressure is maintained. In this embodiment, when the briquette machine 01 is operated, the manual hydraulic pump 35 and the hose that is the pipe line 52 are disconnected from the valve 36.

In order to release the force that the cylinder rod 51 in the hydraulic cylinder 31 presses the movable bearing unit 17, the following operation is performed. First, as shown in FIG. 6, the manual hydraulic pump 35 and the valve 36 are connected by a hose that is a pipe line 52. Next, the valve 36 is opened. With the above operation, the hydraulic oil fed into the hydraulic cylinder 31 returns into the manual hydraulic pump 35, so that the force with which the cylinder rod 51 presses the movable bearing unit 17 can be released.

When a raw material is supplied between the first roll 11 and the second roll 12 and a pressing force is applied between the first roll 11 and the second roll 12, it acts between the cylinder rod 51 and the movable bearing unit 17. The pressure to be detected is detected by the load cell 32. A signal corresponding to the pressure is input to a feeder control unit in the control panel 20 via an adder and an amplifier.

The feeder control unit determines whether or not the pressure detection value by the load cell 32 is within a predetermined range. When the pressure detection value is within a predetermined range, the rotation speed of the feeder screw 19 is maintained as it is.

On the other hand, when the pressure detection value is outside the predetermined range, the feeder control unit determines whether the pressure detection value is larger or smaller than the predetermined range. When the detected pressure value is larger than a predetermined range, the motor 23 with speed reducer is controlled so that the rotational speed of the feeder screw 19 is reduced. On the other hand, when the pressure detection value is smaller than a predetermined range, the motor 23 with speed reducer is controlled so that the rotational speed of the feeder screw 19 is increased.

If foreign matter is mixed between the first roll 11 and the second roll 12 and an abnormal pressing force acts between the first roll 11 and the second roll 12, this impact is transferred to the movable bearing unit 17. And transmitted to the cylinder rod 51 through the load cell 32. The impact is absorbed by the cylinder rod 51 being moved against the resistance force of the hydraulic pressure.

The operation of the drive unit 15 and the motor 23 with a speed reducer can be performed by the touch panel 34 provided in the control panel 20. The operation using the touch panel 34 is a manual operation. Here, the manual operation means that the operator performs each operation of the drive unit 15 and the motor 23 with a speed reducer, which will be described later, on the touch panel 34.

The operation of the drive unit 15 can be performed by the touch panel 34 electrically connected to the drive control unit. Specifically, the operation of the drive unit 15 includes starting, stopping, and increasing / decreasing the rotational speed.

The operation of the motor 23 with a reduction gear can be performed with the touch panel 34 electrically connected to the feeder control unit. Specifically, the operation of the motor with a reduction gear includes starting, stopping, and increasing / decreasing the rotational speed.

Further, the operation of the drive unit 15 and the motor 23 with a speed reducer may be performed with the control button 33. The operation by the control button 33 is an automatic operation. Here, the automatic operation is to set the above-described operation items on the touch panel 34 in advance for the drive unit 15 and the motor 23 with a speed reducer, and start or stop based on the settings. By pressing a start button (not shown) in the control button 33, the drive unit 15 and the motor 23 with a speed reducer are started as described above, and by pressing a stop button (not shown) in the control button 33, The drive part 15 and the motor 23 with a reduction gear are stopped according to the setting mentioned above.

Furthermore, when an abnormality occurs in the above-described device operated by the control panel 20, the device is set to automatically stop. At the same time, the touch panel 34 displays that an abnormality has occurred in the device and that the device has been automatically stopped.

According to this briquette machine 01, the installation space of the load cell 32 can be reduced as compared with the prior art. When connecting the load cell 32 to the briquette machine 01, no fixture is required, so the total weight of the briquette machine 01 can be reduced.

Moreover, according to this briquette machine 01, when operating the drive part 15 and the motor 23 with a reduction gear, starting, stopping, various settings, etc. can be operated with the control button 33 and the touch panel 34. In particular, the touch panel 34 visually recognizes information such as various settings and abnormalities, and is easy to operate. This significantly improves workability.
