Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a disc cutter that revolves around a base axis while rotating on its own axis, and a rod-shaped m 9J @ object that is transported below the base axis in the axial direction by the disc cutter. This invention relates to an apparatus for cutting two pieces of blade-like objects 9J that can be sequentially cut into predetermined sizes.

In the conventional rotary knife-type rod-shaped object cutting machine EaH of this plate, the rod-shaped workpiece is intermittently transferred one after another by a predetermined size below the base axis, which is the public center of the disk blade. In parallel, the wave-cutting object is sequentially cut by the disc cutter according to the size of each feed, but in this conventional low-speed cutter blade-shaped object cutting device, the workpiece is cut 91VR111.

It has a mounting plate tOb with a vertical plane in one direction.

The disc cutter rotary casting spout t has base bals at both ends of the rotary frame 3/.
They are installed at symmetrical positions with +27 in between, so that the balance of the rotating frame 3/ is maintained when the base shaft 2/ rotates.

This disc knife surface transformation r:! iV is a flat plate lI of plywood tO
N! , 21 and rotated by the motor lIl, and a disc cutter 11.3 attached to the tip of the rotation shaft 11.2.
It is made up of spring. The disc blade 11711/-3 rotates on its own axis when the rotating shaft 2 is rotated, and also revolves around the base shaft 2 when the base shaft 2 is rotated. When the disk cutter I13 rotates downward, the wave-cutting Ur object transfer device [/
It is designed to cut a log 2 that is continuously transported over the log. In addition, in this embodiment, the disc cutter 3 is the rotary frame 3.
/ is provided at each end of the disk blade rotating device t, so that the cutting action is performed twice each time the base shaft 21 rotates once. However, in other embodiments, the disk blade rotating device t is installed only on one end of the rotating frame 3/, and the base @2/7
Seven cutting operations may be performed in one rotation. Incidentally, the opening to the motor tag / is through a slip ring 20 provided on one end of the base shaft 2/, and further through the inside of the hollow base shaft 2/ to the motors II/ and 4L/.

Rotating frame shaking equipment! is for displacing the disc blade 9113 in the transport direction of the log 2 in synchronization with the transport progress during the cutting action by the disc blade ≠ 3. Specifically, the rotation frame 3/ is moved from the base axis 2/ While rotating the rotating frame 3
This is done by swinging / along the axial direction of the base shaft 21.

This rotary frame rocking casting spout 3 is installed upstream of the rotary frame 3 in the log feeding direction, and when the rotary frame is rocking, an operating rod 3g provided on the rotary frame 3 is used. , Excited Hinoki s at the tip of 3r
A cam spout S/ from which o and so rotate and exit is provided.

This cam socket 5/ is formed by removably casting a dish-shaped cam member 3 on a circular mounting base 3.2 fixed to a fixed bearing 2.2. Note that this cam member S3 is attached to the mounting base 51 by, for example, a bolt! t/I (1,2[ff
1), and in this embodiment, the cam member 53 is divided into two to facilitate its removal. The cam surface 53 of the cam member 3 is located on the rotating frame 31 side, and the cam surface 3cc has cam peaks and cam valleys formed at opposing positions across the base shaft 2. . In addition, in this cam portion master 3, when the rotating frame 3/ is in a horizontal position as shown in FIG. The rotor O of the operating rod 3g on the upward swing side is positioned so that it rides on the cam ridge of the cam surface 336.

The rollers 01!0 of each operating lever 3t13g of the rotating frame 31 are in a state in which both rollers 5o1so are in simultaneous contact with the cam surface 53G of the cam member 33, no matter what rotation position the rotating frame 3/ is in. 3ea't@m

The rotating frame 3/ is prevented from wobbling in the axial direction of the base IF+f1.2/. In addition, each roller (7, evening O) is
That - the power roller! When O is in the upward stroke toward the cam peak of the cam member 53 (or the downward stroke toward the cam valley), the other roller 50 is in the downward stroke toward the cam valley (or the upward stroke toward the cam peak). It is set as follows. Therefore, during the upstroke, the end of the rotating frame 3 on the roller jO side gradually moves forward (arrow 1) with the pivot point E*3j in the middle.
3] At the same time, the end side of the rotating frame on the opposite side (roller SO side during the downward stroke) begins to lean toward the rear side (direction), and the rotating frame The disc cutter 'A3.113 designed on both pant parts of 3/ moves forward and backward in the handling direction (arrow λl, N direction) along with the concave opening of rotating frame 3/. In addition, when the circular transmission 3/ is excited, the rotation @I1.λ is always maintained parallel to the base axis 2/, so the disc blade II3 is always It is oriented in the overlapping direction with respect to the base IN+2/.

The cam surface 3Φ of the cam member 3 is located slightly above the position in the revolution direction of the circle 1 on the downward rotation side and the position where the plate edge 3 contacts the log 2, as shown in the figure and the guide diagram. flB (
From a position rotated downward by an angle of approximately 33" from the position G directly above the base shaft, through the position directly below the base shaft 2/ (position C), slightly below the position in the revolution direction from which it separates from the engagement with the log 2. The revolution angle range ε (
In this example, the range C' corresponds to the angle (approximately the range of the tag)
Now, a linear up-sloping surface with the same inclination angle e (this linear up-sloping surface is a part that moves the disc cutter t3 forward at a constant speed in the transport direction of the log 2, as described later, so the following 1.
When the downwardly rotating side disk cutter t3 passes through the revolution angle range C from the position B to the position i1D, the other upwardly rotating side disk cutter t3 passes through the revolution angle range C from the position B to the position i1D. In the range C' corresponding to the revolution angle range C in which 3 revolves (the range of angle about qO'' from position faF to position WIH, which is symmetrical with the revolution angle range C), there is a linear downward slope with the same inclination angle e. (This linear downward slope is a part that acts to move the other disc knife 13 back at a constant speed in the direction opposite to the transport direction of the log 2 in response to the disc knife t3 that is moving forward at a constant speed.) In the following, it is referred to as a cam surface portion for constant velocity backward movement).In addition, cam surface!; Two cam surface portions formed between the cam surface portion for constant speed forward movement and the cam surface portion for constant speed backward movement at 3cL. (Intermediate cam surface part) b', a
'A disc blade'j! 1jl13. In front of l13, it is formed into a gently curved shape in order to prevent excessive acceleration from occurring during reverse drive.

By setting the shape of the cam surface 33cz of the cam member 53 as described above, the rotating frame 3/ is placed in the horizontal position (
The disk cutter t3 is rotated in the direction of arrow R from positions A and E), and the downward rotating disk cutter ≠3 is at position B.
In the revolution angle range α (angle range of approximately waO@), which rotates from the direction @C directly below the base axis λ/ to the position, the downward rotation side disc blade @J1/-3 is rotated in the log transfer direction (arrow N direction) at a speed equal to the transport speed of the logs, and during that time the logs z and z are cut. Fig. r) is called the cutting revolution angle range), and the disc blade '13 is at
Diagonally upward direction g from ftD through lateral ME of base axis λl
In the revolution angle range that rotates up to 1F, the disc blade t13
from the forward direction (arrow N direction) to the backward direction (arrow N direction)
You will be able to change direction smoothly.

In addition, the other disc cutter 4!3 (the disc cutter l13 on the side that rotates upward from the horizontal position of the rotation frame 31) is in the revolution angle ranges C and d that are symmetrical with the revolution angle ranges C and b. The action of the disk cutter 13 in the revolution angle ranges a and b is opposite to that in the respective revolution angle ranges a and b.

1 Here, the transport speed of the log 2 (31111 per minute), the length of the 7 products obtained by cutting the log 2 (P), the rotation speed of the rolling frame 31 (n revolutions per minute), and the cam To clarify the relationship between the range Φ' and the inclination angle θ of the cam surface portion for constant velocity advancement on the surface j3α, 11! of the cam surface portion for constant velocity advancement on the cam member j3! ! The surrounding float ' and its inclination angle e are determined and selected as follows. That is, now disc knife 1
/-3 revolves by an angle γ < VV diagram), a cutting action is performed on one log 2, and during that
Suppose that it moves forward at a constant speed by a distance Fif (Figure W),
The cam member 53 has an inclination angle θ of the cam surface portion for constant velocity advancement so that the disc cutter lI3 can be uniformly advanced by the same length as the above-mentioned @f within the angular range V' corresponding to the angular range ν. is determined, and furthermore, the disk cutter ≠ 3 should move forward at the expected speed (distance The height range C' of the cam surface for constant velocity advancement is determined so as to maintain M e ).

Expressing this mathematically, the log 2 moves forward by a distance of 2P while each disc cutter≠3゜13 revolves (3゜O), so while cutting one log 2 (revolution angle range p)
The distance that log 2 moves forward is 8... (1
)! =2PX-g-5-.

The cam member 33 moves the disc cutter ≠ in accordance with the forward movement of the log 2.
3 must be moved forward, so the disk blade '1lt3
It is necessary to obtain a cam height f' corresponding to the log advancement amount f in an angular range t' on the cam surface corresponding to a revolution angle range t. Therefore, f'oe y' ・ta
nθ --- (, 2) holds, and since f' and V' are equal to or directly proportional to V, respectively, and from equation (1), Since v3O, the inclination angle e of the constant velocity advancing cam surface is determined according to the relationship tenθcf-Pcc-- (4m).

Next, the cam parts! In 3, the range of the entire range (angular range C', height range t') of the uniformly advancing cam surface should be determined by the sliding speed of the log Z, the PE plate blade I/, and the cutting of 3. It is determined by the number of rows of logs 2 to be processed (two rows in the illustrated embodiment), etc., and in reality, the disc cutter 13 cuts all the rows of logs z,
The range required to cut z (angular range X in Figure 9)
/, height range e/).

Regarding the same cutting device, the number of log rows is usually fixed, so in order to correspond to changes in the product length P, the rotation speed n of the rotary rod 3/or the floating of the log 2 is changed. It is only necessary to change the speed S and change the shape of the broom speed forward cam surface portion on the left cam member 3 (replace the cam member 33).
