The present invention having the above-described structure has the following functions. When the disc on which the blade is attached is driven and the raw material is supplied into the hopper, the pusher in the hopper pushes the raw material toward the outer surface of the disc by the pressing means, and accordingly, the blade of the disc is cut. Cut into the raw material, and this cutting force tends to pull it in the direction of rotation of the disk, that is, downward, and the pulling force pushes the pusher back against the pushing force of the pushing means. The raw material is directly exposed to the blade.

Then, the raw material is fed to the outer surface of the disk by the pressing means along with the cutting by the cutting tool, and the cutting progresses sequentially.

When the cutting is completed or near the end of cutting, the raw material is re-supplied between the pusher and the disc, so that the pusher retracts along with the cutting of the disc blade and the raw material faces the blade. Cutting is continued by repeating this operation, and automatic and continuous knot cutting can be performed.

Therefore, it is possible to perform joint cutting without interruption while the push lever is still in the pressed state by the pressing means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a raw material feeding method for a scraping machine and a scraping machine according to the present invention will be described below with reference to the drawings.

In FIGS. 1 and 3, A is a knot shaving machine,
Thin sliced pieces using raw material b such as bonito flakes and mackerel flakes,
For example, in the case of continuously mass-producing flower bonito and the like, a disk 3 supported by a machine body 1 and attached with a large number of blades 2,
The hopper 4 for the raw material b provided in the machine body 1, a pusher 5 provided in the hopper 4, and a pressing means 6 of the pusher 5 are basically configured.

The disk 3 is supported by a support shaft 7 horizontally extending over the machine body 1 such that its outer surface 8 is vertical, and is rotated at a predetermined speed by a drive means c such as a motor. A large number of blades 2 are attached to the outer peripheral portion at intervals in the radial direction by adjusting the protrusion of the blade according to the thickness of the shavings to be manufactured, and facing the blade edge from the outer surface 8.

The hopper 4 accommodates the raw material b in a vertical direction, and is attached to the machine body 1 so as to correspond to the blade 2 on the outer surface 8 of the disk 3, and the raw material b is placed below the hopper 4. Bottom part 4a that regulates falling and holds it in place
And a receiving blade 2a for the blade 2 attached to the disk 3 is fixed to the front edge of the bottom portion 4a.

The push lever 5 is attached to the inside of the hopper 4 so as to move back and forth toward the outer surface 8 of the disk 3, and is formed in a plate shape as shown in FIGS. 1 and 4. A blade 2 protruding from the outer surface 8 of the disk 3
A corresponding portion of the parallel surface 5a which is substantially parallel to the outer surface 8 and first and second inclined portions 5b and 5c which are inclined backward as going upward from the parallel portion 5a, The parallel portion 5a faces the position when the blade 2 is in a horizontal posture due to the turning of the disk 3, so that the yield of the raw material b is not shortened or the shavings are shortened due to an unbalanced cutting load. Then, it is possible to further cut the raw material b to the end.

The first inclined portion 5b is rearward inclined by about 10 degrees with respect to the parallel portion 5a, and the raw material b is cut between the outer surface 8 of the disk 3 and the push lever 5 by cutting. A posture is formed in which the raw material b is easily drawn downward, and the excessive supply of the raw material b is prevented. Further, the second inclined portion 5c is further 16 to 17 relative to the first inclined portion 5b. Since it is provided with an inclination of less than 30 degrees with respect to the parallel portion 5a, a large opening for charging the raw material b is formed above the hopper 4 when it is stored in the hopper 4. To be done.

A reinforcing piece 5d of substantially the same shape is attached to the back side of the parallel portion 5a of the push lever 5.

The pressing means 6 is linked to the pusher 5 to press the raw material b at a constant pressure, and the raw material b introduced into the hopper 4 is cut by the cutting resistance of the blade 2. The push lever 5 retreats in response to pulling in, and can be adopted by bullets such as pneumatic cylinders and springs. In the present embodiment, an example of pneumatic cylinder is shown.

In this example, an advancing / retreating plate 10 is attached to a hopper base 9 attached to the machine body 1, a pneumatic cylinder 11 is fixed on the advancing / retreating plate 10, and the push bar 5 is attached to the outer end of the rod 12. Is attached so as to obtain the above-mentioned predetermined angle, and the relief valve 13 is linked to the pneumatic cylinder 11, and the pressing force by the air pressure is always kept constant, and the blade 2 group By appropriately releasing the pressurization in the cylinder caused by the material b being drawn downward by the cutting by the relief valve 13, the rod 12 retracts and the material b
Can be automatically supplied to the blade 2.

The forward / backward movement of the push lever 5 by the operation of the pressing means 6 is appropriately controlled by the detection signals generated by the detecting means 14 and 16.

Of these, the detection means 16 detects the forward limit position of the push lever 5, and uses a proximity switch such as a magnet switch, a photoelectric tube, a limit switch or the like. In this embodiment, the cylinder is used. 11 is a proximity switch that reacts with the piston, and shows a state in which the cutting of the raw material b is completed and the parallel portion 5a of the pusher 5 is close to the cutting edge of the cutting tool 2 on the outer surface 8.
When the detection means 16 detects for a certain time while the
Since there is an abnormal state such as a bridge in the hopper 4,
This detection signal is transmitted to the pressing means 6 and causes the push lever 5 to retract so that a large opening is generated between the disk 3 and the push lever 5, and the raw material b that has become a bridge is dropped to correspond to the abnormal state. ..

Further, the above-mentioned detecting means 14 is provided with a push lever 5
For detecting the range immediately before the forward limit and the backward limit in the movement of the rod, using a photoelectric tube, a proximity switch, a limit switch, etc.
When the detector 15 attached to 12 or the like corresponds to this, since the specified amount of the raw material b is being supplied into the hopper 4, the raw material supply means W is stopped while this detection signal is issued.

Further, when the detection by the detecting means 14 is not carried out, the raw material b in the hopper 4 is almost finished with the cutting or the cutting is finished, so the raw material supplying means W is driven. The raw material b is supplied to the hopper 4.

The supply means W for supplying the raw material b is formed in a cylindrical shape and rotatably supported on the machine body 1 by a driving member (not shown). A predetermined amount is retained, and the spiral wall 18 is wound from the inlet side toward the outlet side on the inner circumference of the drum 17 arranged at an upper slope where the outlet side is higher than the inlet side, A spiral path 19 is formed in between, and the raw material b moving along the spiral path 19 continuously drops from the outlet side through the chute 20 to the hopper 4 one by one.

In FIG. 2, 21 is the hopper 4 described above.
The raw material detecting means provided above the device uses a photoelectric tube, a proximity switch, a limit switch or the like, and when the raw material b is accumulated above the hopper 4, this detection is performed in parallel with the detection of the detecting means 16. At some time, the driving of the supply means W is stopped.

Next, the operation of the knot shaving machine A according to the embodiment of the present invention will be described. The disk 3 having a large number of blades 2, 2 ... Attached thereto is rotated by the drive means c continuously at a predetermined speed and down-cutting with respect to the raw material b in the hopper 4, and the supply means W is rotated. Then, when the raw material b is charged into the hopper 4, the raw material is supplied vertically between the push lever 5 in the hopper 4 and the outer surface 8 of the disk 3, and the raw material supply means is detected by the raw material detecting means 21. Stop W.

Then, the pneumatic cylinder in the pressing means 6
Since the push lever 5 attached to the rod 12 of 11 pushes the raw material b toward the outer surface 8 of the disk 3 with a predetermined pressure, the blade b is moved to the outer surface 8 of the raw material b by the rotation of the disk 3. Cut in the lower part, and this cutting resistance causes disk 3
The pulling force of the push lever 5 is pushed back against the pneumatic pressure of the pneumatic cylinder 11 in the pushing means 6, so that the raw material b is pulled by this pulling force. The raw material b is stored in the bottom part 4a of the hopper so that the raw material b faces the group of swiveling blades 2 in a vertical vertical position and is pressed by the push lever 5 so as not to move due to resistance during cutting. It

Then, in this state, the raw material b is cut by the rod 12 of the pneumatic cylinder 11 by the pressing means 6 having a constant pressing force and the outer surface 8 of the disk 3 is cut by the rod 12 of the pneumatic cylinder 11. Is gradually fed out, and a vertically long non-defective shaving with a constant blade thickness is continuously manufactured.

When the raw material b held between the disk 3 and the push lever 5 has been cut in this manner, the detecting means 14 causes the detector
The detection is canceled because it goes out of the detection range of 15, and the supply means W is activated by this, and the drum 17 starts to turn, so that the raw material b moved upward along the spiral path 19
The raw material b is supplied again between the push lever 5 and the disc 3 while being guided to the second inclined portion 5c of the push lever 5 from the exit side of the terminal end to the chute 20.

The supplied raw material b is the rotating disk 3
Since it is drawn below the hopper 4 as the group of blades 2 is cut, the pressing lever 5 resists the pressing force of the pressing means 6.
Moves backward by the thickness of the raw material b, and the raw material b is at the bottom of the hopper 4.
4a is reached and the cutting is continuously faced to the blade 2, and the replenishment of the new raw material b is carried out one after another by the slight retreat of the pusher 5, and the presser is repeated by repeating this operation. No. 5 can automatically and continuously produce a shaving in a pressed state.

In the above-mentioned operation, when the raw material b is not drawn into the hopper 4 and bridges (deposits) on the upper part of the hopper 4, the raw material detecting means 21 provided on the upper part of the hopper 4.
Detects the accumulation of the raw material b and stops the supply means W accordingly.

In this case, after a certain period of time, about 1 to 2
By moving the pusher 5 to the retreat limit for a second and opening the inside of the hopper 4 largely, the raw material spontaneously falls, the bridge is eliminated, and the cutting operation is restarted.

Further, when the bridge is not eliminated by the above operation, or when the raw material b is not supplied even if the detection means 21 detects that the raw material b is not present, the blade 2 is further cut.
When the cutting ability is lowered due to the influence of the raw material b or the like, an alarm means (not shown) for visual and auditory senses is activated.

[0037]

As described above, the method for feeding a raw material for a scraping machine and the scraping machine of the present invention are for re-feeding after finishing the scraping of a raw material. As the material is retracted, the material is retracted by the necessary amount so that it can be accommodated between the disc and the pusher, and the blade is immediately used for cutting.Therefore, there is no useless movement to move the pusher back and forth. Can always perform continuous and efficient scraping in the pressed state.

Further, in the supply of the raw material, as described above, since the push lever is not opened greatly but is closed as described above, in cooperation with the inclined portion formed on the push lever,
The lower part of the raw material is cut and drawn into the hopper, and the material is correctly inserted vertically according to the gap,
Sliced pieces that are scraped without causing the raw material to be clogged can yield a vertically long good product. It has special effects such as.
