Description

[Detailed description of the invention] (Field of industrial application) The invention uses a rotating blade in which the blade is installed obliquely to the rotation axis and the outer diameter of the cutting edge at the inner end is larger than that at the outer end. This is an anti-slip machine that makes incisions at the tips of bamboo shoots, and is used in the pre-process of peeling the bamboo shoots.

(Prior art and its problems) The applicant has proposed a device in Japanese Patent Laid-Open No. 57-198076 in which a rotary blade is placed above a conveyor belt in order to prevent the tips of the bamboo shoots from breaking during the process of peeling the bamboo shoots. I am proposing it first.

As shown in FIG.
A blade with an inner end higher in height than the outer end is installed on the outer peripheral surface of a cylindrical roll, or a blade with approximately equal height on both the inner and outer ends is installed on the outer peripheral surface of a truncated conical roll. A rotary blade 5 is arranged such that the outer diameter of the cutting edge on the inner end side is larger than that on the outer end side, and a large number of diagonal cuts are made at the tip of the bamboo shoots that are advanced on the endless belt 4. It is used to loosen the densest parts of the skin.

This device is effective in preventing the tip of the bamboo shoots from breaking during the post-process peeling work using rollers, etc., by preventing the tips of the bamboo shoots from getting wedged together with the skin, but the bamboo shoots collide with each other around the rotating blade. This caused the inconvenience of having to adjust the arrangement of the bamboo shoots because the arrangement of the bamboo shoots would be disturbed or run over.

This is because the bamboo shoots are automatically moved forward by an endless belt.

In other words, when the rotary blade bites into the tip of the bamboo shoot, the tip is momentarily rotated and pressed to both sides of the belt, and the forward speed of the bamboo shoot becomes smaller than the advancing speed of the belt, causing the root side of the bamboo shoot to swing and tightening the belt. The bamboo shoots may be located diagonally to the direction of movement of the bamboo shoots, and if the bamboo shoots are slightly thin or light, the degree of shaking is large, and the shaken bamboo shoots will collide with the bamboo shoots that are moving forward one after another on a belt. This causes the bamboo shoots to form a dumpling in front of the rotary blade, and the tips of the bamboo shoots are removed from the position of the rotary blade, resulting in bamboo shoots that cannot be cut.

(Technical issue) The present invention involves cutting into the tip of a bamboo shoot using a rotary blade with a blade set diagonally to the axis of rotation and the outside diameter of the cutting edge at the inner end being larger than that at the outer end. The object of this invention is to use a pre-fold prevention machine to smoothly unravel the tips of a large number of bamboo shoots.

(Technical means) The technical means for solving this technical problem are (a) disposing a rotating guide roller below the rotary blade, and (b) enabling the guide roller to move up and down. .

(Effect of technical means) The bamboo shoots are held by the root side in the hand and guided between the rotating blade and the guide roll.

Since the guide roll rotates, there is no resistance to the movement of the bamboo shoots, and the tips of the bamboo shoots that are moved by holding the root side are surely cut.

Moreover, since the guide roller can be moved up and down,
This means that the tips of bamboo shoots, from thin to thick, can be unraveled smoothly regardless of their size.

(Effects of the present invention) As a result of being able to smoothly unravel the tips of the bamboo shoots, the bamboo shoots do not collide around the rotary blade, and the tips of all the bamboo shoots can be cut and loosened.

Therefore, unresolved bamboo shoots will not be transferred to the subsequent peeling process, and at the stage of peeling the bamboo shoots,
It has the advantage of producing bamboo shoots that do not break.

Also, compared to an endless belt, it does not require large-scale equipment to raise and lower, and has the advantage that it can process everything from large bamboo shoots to small bamboo shoots with one machine.

(Embodiment) The guide roller in the above technical means may rotate freely and follow the movement of the bamboo shoots, or
The bamboo shoots may be rotated on their own axis to promote the movement of the bamboo shoots together with the rotary blade.

(Example) Next, a specific example of the above technical means will be described with reference to the drawings.

In FIGS. 1 and 2, the rotary blade 15 is located inside and pivotally supported by a support frame 12 having a U-shaped cross section that projects from the upper part of the frame 11, and is rotated by a drive means (not shown).

The rotary blade 15 has a blade 17 on the outer circumferential surface of the cylindrical roll 16, with the blade height on the inner end 18 side being higher than the outer end 19.
are planted diagonally with respect to the shaft 20 of the roll 16.

A guide roller 21 is arranged below the rotary blade 15. The roller 21 in this embodiment is an idle roller, and as shown in FIGS. 1 and 3,
Guide rods 22, 22 are fixed to the frame, a nut 24 is formed at one end of the support shaft 23, and this is connected to the spiral rod 2.
5, and the roller 21 is raised and lowered by turning the spiral rod 25 with a handle 26.

When driving the roller 21, care must be taken not to interfere with the drive transmission mechanism, such as by raising and lowering it together with the driving means.
