Description of the Related Art A cereal mill for milling grains such as rice and barley includes a friction type mill for removing a bran layer on the grain surface by a frictional force acting between the grains, and a mill roll. There is a grinding type grain milling device which forcibly removes a bran layer on the grain surface by a large number of abrasive grains formed on the surface of the grain. Hereinafter, the outline of each apparatus will be described. However, since the grinding type milling apparatus will be described in detail in the embodiments of the present invention, it will be briefly described here.

FIG. 6 shows a conventional vertical friction milling device 13.
0 is shown in a vertical sectional view. As shown in this figure, the vertical friction milling device 130 has a driving mechanism 132 forming a lower portion of the device, a friction milling portion 134 forming an upper portion of the device, and a grain forming an upper end of the device. The particle transport unit 136 is a main part. A rotating spindle 138 is provided upright at the center of the vertical friction milling device 130. A spiral 140A is provided at the upper end of the rotating spindle 138.
And a grain feed roll 140 that rotates integrally with the rotary spindle 138 is provided in a state housed in the housing 142. In addition, a friction type milling roll 144 having a pair of key-shaped protrusions 144A and rotating integrally with the rotary spindle 138 is provided below the rotary spindle 138 at the grain feeding roll. Around the friction type milling roll 144, a perforated cylindrical milling cylinder 146 is provided.

The partition plate 148, which is also the top plate of the drive mechanism 132, has a tapered cutout port 150 formed therein. At the position where the discharge port 150 is formed, a dish-shaped annular resistance valve 152 that is vertically movably fitted to the rotating main shaft 138 is disposed. This annular resistance valve 15
A milling resistance adjusting motor 158 is connected to 2 via a link 154 and a milling resistance adjusting spring 156. In addition, below the annular resistance valve 152, a discharge gutter 160
Is provided with a bottomed cylindrical discharge case 162 to which the base end is connected. The discharge case 162 accommodates a dish-shaped discharge plate 164 that rotates integrally with the rotating main shaft 138.

According to the above configuration, when the rotary main shaft 138 rotates around its axis, the grain feeding roll 140, the friction type milling roll 144, and the discharge board 164 are integrally rotated. In this state, when the grains are supplied from the grain feeding pipe (not shown) into the grain feeding chamber 166 of the grain transport unit 136, the grains are fed to the grain feeding roll 1
By receiving the conveying force downward from the apparatus by the spiral 140A of 40, the spiral is transported into the friction milling chamber 168 of the friction milling unit 134. On the other hand, the annular resistance valve 152 is urged by the milling resistance adjustment motor 158 to a predetermined pressure, and
50 is closed so that a predetermined pressure acts on the grains in the friction milling chamber 168. Under these circumstances,
By rotating the friction milling roll 144, the ridge 1
The grains in the friction milling chamber 168 are stirred by 44A,
The bran layer on the grain surface is torn away by frictional force acting between the grains. Thereafter, the cereal-processed grains push the annular resistance valve 152 to open the outlet 150.
, Falls on the rotating discharge plate 164, and is discharged out of the apparatus from the discharge gutter 160.

[0006] When the pressure applied to the grains conveyed into the friction milling chamber 168 by the grain feed roll 140 exceeds a predetermined pressure set by adjusting the annular resistance valve 152, the grains cause an annular resistance. The valve 152 is pushed downward against the urging force of the milling resistance adjusting spring 156, and the opening area of the outlet 150 is increased. Accordingly, the pressure acting on the grains in the friction milling chamber 168 is maintained at a predetermined pressure.

On the other hand, FIG. 7 shows a schematic configuration of a conventional vertical grinding type grain mill 170 in a vertical sectional view. As shown in this figure, a vertical grinding type grain mill 170 includes a driving mechanism 172 constituting a lower part of the apparatus, a grinding type grain processing part 174 constituting an upper part of the apparatus, and a grain constituting an upper end of the apparatus. The particle transport unit 176 is a main part.

Further, the grinding type mill roll 18 on the rotating spindle 178 is provided.
A discharge plate 190 accommodated in the discharge case 188 is disposed below the discharge case 4. A discharge port 192 is formed on a side portion of the discharge case 188, and a discharge gutter 194 is connected to a position where the discharge port 192 is formed. Further, in the vicinity of the discharge port 192, a plate-shaped resistance valve 196 has a support shaft 198.
It is attached so that it can rotate around. A milling resistance adjusting motor 204 is connected to the plate-shaped resistance valve 196 via a link 200 and a milling resistance adjusting spring 202.

[0008] According to the above configuration, when the rotating main shaft 178 rotates around its axis, the grain feeding roll 180, the grinding type milling roll 184, and the discharge board 190 are integrally rotated. In this state, when the grains are supplied from the grain feeding pipe (not shown) into the grain feeding chamber 206 of the grain transport unit 176, the grains are fed to the grain feeding roll 1
By receiving the conveying force downward from the apparatus by the spiral 180A of the 80, the helical material is conveyed into the grinding and milling chamber 208 of the grinding and milling unit 174. On the other hand, a predetermined pressure is applied to the plate-shaped resistance valve 196 by the milling resistance adjustment motor 204, and the discharge port 1
92 is closed, so that a predetermined pressure acts on the grains in the grinding and milling chamber 208. Under these circumstances,
By rotating the grinding-type milling roll 184, the bran layer on the grain surface is scraped off by a number of abrasive grains formed on the outer peripheral surface of the grinding-type milling roll 184. Thereafter, the cereal-processed grains push the plate-shaped resistance valve 196 and open the outlet 192.
, Falls onto the rotating discharge plate 190 and is discharged from the discharge gutter 194 to the outside of the apparatus.

Therefore, in order to solve such a problem, the discharge case 16
The drain gutters 160 and 194 can be attached to both sides of the apparatus 2 and 188 (the left and right sides of the apparatus in FIGS. 6 and 7). It is conceivable that the remaining outlet is closed with a lid or the like.

[0011] However, even with the above configuration, another problem still remains. That is, the conventional vertical friction milling device 130 and the vertical grinding milling device 1
In 70, the operation panel is fixedly installed at the center of the front of the friction type milling processing section 134 and the grinding type milling processing section 174 which can be said to be the main body of the apparatus. The distance between the operation for grasping the actual state of the grain after the grain processing (the operation by visual inspection, the operation by touch, etc.) is widened, which is a troublesome operation. Therefore, in this respect, the conventional grain mill has room for improvement.

The discharge chamber is provided with a pair of discharge openings at two opposite positions, one of which is connected to discharge means, and one of the discharge openings is closed. Since the means is attached and the other discharge opening is closed, the grain processed by the grain processing unit is sent to the discharge chamber and then discharged to the discharge means connected to the discharge means. The liquid is discharged from the discharging means to the outside of the apparatus through the opening.

Here, in the present invention, the operation panel for controlling the operation of the grain milling apparatus is itself movable, and is installed on the side where the discharge means is connected around the grain processing section. The distance between the discharge means and the operation panel is reduced, and both the discharge means and the operation panel are located within the reach of one worker. Therefore, the operator can operate the operation panel with the other hand while checking the state of the crushed grain discharged from the discharger after the crushing process with one hand.

0 is only placed on the top plate 18A), and the operation panel 80 is slidably supported by supporting means such as guide rails installed on the top plate 18A. The operation panel 8 can be moved by moving the panel 80 along the supporting means or by a predetermined operation performed by an operator.
And a sensor such as a limit switch around the secondary outlet 82 (in a broad sense, "detection means" for detecting the presence or absence of the discharge gutter 84). When the sensor detects that the discharge gutter 84 is attached, the driving means such as a motor is automatically driven to attach the operation panel 80 to the discharge gutter 84. This is a meaning including a configuration for moving to the side that has been set.

In this embodiment, two types of discharge chambers (the primary discharge chamber 64 and the secondary discharge chamber 60) are provided in the discharge processing section 52.
Has been described by way of example, but is not limited to this, and may be applied to a configuration having only one type of discharge chamber (for example, a configuration as shown in FIG. 7 described in the section of the prior art). The present invention may be applied.

Further, in the present embodiment, the present invention is applied to a so-called vertical grinding machine 10 of a so-called descending type in which grains move downward along the rotating spindle 20 by operating the apparatus. However, the present invention is not limited to this, and the present invention is applied to a so-called ascending type vertical grinding type grain mill in which grains move upward along the rotary spindle when the apparatus is operated. You may. Further, the present invention can be applied to a vertical friction milling machine outlined in the section of the prior art. Furthermore, the present invention is not limited to being applied only to a vertical grain mill, but is also applicable to a horizontal grain mill.
