Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention, as seen in a rolling bar steel refining facility, provides a long rod-shaped carrier from one end to the other end of a cooling bed composed of a rake device. A new transfer means that improves the transfer content of rod-shaped transfer material on the same cooling floor in the case where natural cooling is performed during successive automatic transfer, and the product is obtained by cold cutting to a fixed size. Regarding the provision of.

(Prior art) Rolled steel bar material that has left the steel bar rolling equipment is transferred to the conditioning equipment side in a long length, and while being conveyed in parallel on a cooling floor composed of a moving rake and a fixed rake in the equipment. It is known that this is naturally cooled, and a plurality of cooled steel bars are transferred as a group to a cold cutting device (cold shear) and cut into a certain size to obtain a product. The outline will be explained with reference to FIGS. That is, in FIG. 6, the length L (m) from the steel bar rolling equipment (not shown)
The steel bar material A ₁ divided into pieces is continuously transferred to the cooling bed B by the run-in roller 1 every time T (sec) (= L / V) at the moving speed V (m / sec). It is carried to the entrance side and is transported to the position A _{4 in the} figure through the alternate lifting and lowering of the first lifter 2 and the second lifter 3 which can be moved up and down installed at the entrance. The cooling floor B is composed of a moving rake 4 and a fixed rake 5 as is known, and both rakes 4 and 5 support one of the steel bars A on each upper edge of a strip plate extending in the transport direction. Bearing grooves 4a and 5a are arranged in a row as shown in FIG.
At this time, the fixed rake 5 is held by the fixed frame 5b, and the moving rake 4 is supported by the eccentric cam 4d of the drive shaft 4c and is given a circular motion. The steel bar material A at the position A _{4 in the} figure will be scooped into the first bearing groove 5 a of the fixed rake 5. Since each of these movements is continuously carried out while the bar steel material A is continuously carried in by the run-in roller 1 to one, each bar steel material A starts from the first supporting groove 5a of the fixed rake 5. , One after another, which are successively transferred in parallel in the bearing groove 5a of the same lake 5 and moved forward in the conveying direction (leftward in the figure) sequentially.
While the steel bar A scooped by the 5a reaches the last bearing groove 5a in the fixed lake 5, its natural cooling is performed. Thus, the steel bar material A reaching the last bearing groove 5a is moved from the groove to a known accumulation conveyor 6 whose conveyance direction is the same as the conveyance direction to the cooling floor B, and a predetermined number of the steel bars A are conveyed on the conveyor 6. The steel bars A are sequentially arranged in parallel, and the steel bars A on these conveyors 6 are collectively scooped by the traverser and carried out on the runout roller. A cold shear (cooling / cutting device) installed on the downstream side cuts a group of steel bars into a product group by cutting it to a certain size, and in FIG. The aligning roller installed by intervention is shown.

(Problems to be Solved by the Invention) The above-described cooling bed has the following problems. Now the length L of the steel bar A = 75 m, its loading speed V = 15 m / s
If ec, the carry-in cycle from the run-in roller 1 T =
Since 75/15 = 5 sec, there is one line every 5 sec.
Further, the take-in speed of the steel bar material A in the moving rake 4 in the cooling floor B used in the current type of steel bar rolling equipment is generally 1 rotation operation = min.4 sec, 2 rotation operation = min.4 sec + 2.
Since it is possible to operate in a cycle of 5 seconds and 3 rotations = min. 9 seconds, if the loading interval time is short as described above, each bearing groove 5a of the fixed rake 5 (the number of bearing grooves is 90). The steel bar A is taken in, and the top bar A passes through the final bearing groove 5a after 90 times. The time required until then is T90 = 5 × 90 = 450 seconds, and it is structurally impossible to make this cooling time variable. On the other hand, there are various types of steel bar A with large, medium, and small diameters. For example, since steel bar with a small diameter is loaded at a high speed, it is impossible to change the intake cycle, while staying on the cooling floor. Since the time (passing time) cannot be shortened, when cutting with a cold cutting device, the temperature is not optimal for cutting, which causes defects such as a cut surface and age cracking.
It is a big problem that it is difficult to obtain the optimum cutting temperature for each steel bar having each diameter.

Still another problem is that the bar-shaped carrier material is bent during the transportation for performing a natural cooling for a long time on such a cooling floor, which is caused by the fact that it is shown in FIGS. 8 (1) to 8 (3). I will teach you. That is, as described above, in such a cooling bed, the rod-shaped carrier A is conveyed by the bearing groove 4a of the moving rake 4 through the circular motion of the moving rake 4 for each groove of the bearing groove 5a in the fixed rake 5. Therefore, the conventional general cooling floor has the transport contents shown in FIG. 8 (1). In the figure, the moving rake 4 is shown as a circular motion locus for avoiding overlap with the fixed rake (5), D is the circular motion radius, O is the circular motion center, and P is the feed pitch, As indicated by the arrow in the figure, the rod-shaped carrier A located in the bearing groove 5a on the left side in the figure is lifted by the bearing groove 4a (not shown) of the moving rake 4 and inside the bearing groove 5a on the right side in the figure. At this time, with P = D, the circular movement center O of the moving lake 4 is moved so that the moving material 4 does not slip between the moving lake 4 ▲ ← → ▼ conveying material A ▲ ← → ▼ fixed rake 5. It is generally installed as the 1 / 2P position. For this reason, as shown in the figure, the point (a) in the conveying material A always faces in a fixed direction, so that bending in the longitudinal direction inevitably occurs during natural cooling for a long time over the entire length of the cooling bed. Further, as shown in FIG. 8 (2), under the condition of P = D, when the position of the circular motion center O of the moving rake 4 is displaced from the 1 / 2P position by Δi as shown in the figure, the left side of the figure Conveying material A in bearing groove 5a
At the time when the moving material is lifted by the bearing groove 4a (not shown) that performs the circular motion of the moving rake 4, the conveying material A is rotated to the right side in the figure, but the next fixed rake bearing on the right side in the figure is moved. When it is housed in the groove 5a, the carrier material A does not rotate so that a sliding rotation is applied on the groove inclined surface of the bearing groove 5a, so that the point (a) in the figure returns to the original position.

For this reason, as shown in FIG. 8 (3), in order to suppress the occurrence of bending, a means of giving rotation to the conveyed material A by only both the moving rake 4 and the fixed rake 5 has been considered. In the figure, D ₁ is the conveying circular motion radius of the moving rake 4, and other symbols are the same as those in FIGS. 8 (1) and 8 (2),
As shown in the same figure, the condition of D ₁ > P is given, and the circular motion center O of the moving rake 4 is Δi in the horizontal direction under the same condition.
₁ , and Δi ₂ is displaced from the center O ₁ of the fixed rake 5 in the vertical direction. In this case, either Δi ₁ = Δi ₂ or Δi ₁ ≠ Δi ₂ may be used. In this way, the circular movement of the moving rake 4 causes the conveying material A in the bearing groove 5a on the left side in the figure to be carried into the bearing groove 5a in the right side in the figure. Center and moving lake 4 bearing groove
By setting the transfer point 5b (not shown) at the same position as the transfer point (b), the carrier material A in the bearing groove 5a on the left side in the drawing is first transferred to the bearing groove 4a (not shown) in the moving rake 4. When it is lifted with, the transport material A that has been rotated to the right when it is stored in the bearing groove 5a of the fixed rake 5 on the left side in the figure, is stored at the point (b) in the figure while the rotation state is maintained and passed. Will be performed. This means is easy to implement in terms of equipment,
Once the cooling floor equipment was designed and manufactured with the ratio of xP = D ₁ determined and manufactured, the ratio cannot be changed. As the rod-shaped carrier A, the rolled size of steel bars and the like is large and small. Therefore, it is not possible to obtain a satisfactory rotation angle for various sizes over a wide range, and in addition, because the conveyance material A always slips in this conveyance content, surface flaws due to sliding friction are prevented. In addition, it is not suitable for a rod-shaped carrier made of a soft material and is not generally used. Therefore, it is an unsolved problem in terms of eliminating the occurrence of bending.

(Means for Solving the Problems) The present invention is to prevent the above-mentioned problems in the cooling floor, that is, the bending that occurs in the rod-shaped conveying material during conveyance, and to make the constant and constant cooling time variable. The present invention is characterized in that the contents of conveyance are improved so that they can be solved simultaneously, and the feature of the first invention is that a fixed rake and a moving rake that moves up and down and moves back and forth with a constant stroke are provided. A transporting device for a rod-shaped transport material on a cooling floor, which transports a rod-shaped transport material on a fixed rake backward by the moving rake, wherein a stroke of forward / backward movement is variable and can be moved up and down, and the transport material on the fixed rake or the movable rake is also movable. Is equipped with a traverser that can be transported backwards.

A feature of the second invention is that the stroke of the traverse of the traverser is made longer than the pitch of the conveying material supporting groove of the fixed rake, and the traverser can fast-forward the conveying material on the fixed rake. is there.

A feature of the third invention is that the stroke of the traverse of the traverser is made shorter than the pitch of the conveying material supporting groove of the fixed rake, and the traverser moves the conveying material on the moving rake onto the fixed rake. It is configured to be transferred.

(Operation) According to the above-mentioned technical means of the present invention, as shown in FIG. 1, the cooling bed B of the steel bar material A shown above is illustrated in the example of FIG. , The first lifter 2 and the second lifter 3 on the inlet side, and in the cooling bed B constituted by the moving rake 4 and the fixed rake 5, the fixed rake 5 is arranged in the fixed rake 5 in parallel with the same. The lifting rake D conveys the rod-shaped conveying material A by the rotary rake and fast-forward traverser 11 in which a plurality of supporting grooves 11a of the steel bar (bar-shaped conveying material) A supported in the respective supporting grooves 5a are arranged at the upper end. By being provided so as to be able to vertically move up and down orthogonally to the direction so that it can project and retract from the transport surface of the fixed rake 5, and further, the traverser 11 is provided in parallel with the transport direction of the rod-shaped transport material A so as to be able to move straight forward and backward by the forward / backward movement device E First of all, for the first purpose, rod-shaped carrier A Then, when performing a 1-pitch transport without giving a bend by giving rotation at an arbitrary angle, as shown in FIGS. 2 (1) to 2 (8), the traverser 11 is rotated and raked. It is possible by exercising as. That is, in FIG. 2 (1), the fixed rake 5 is shown by a solid line, while the moving rake 4 is shown by its circular motion locus, and the rotary rake traverser 11 is shown by a dotted line, as shown in FIG. However, the traverser 11 is located at a fixed position in the figure and below the fixed lake 5. The rod-shaped conveying material A placed on the bearing groove 5a of the fixed rake 5 is moved from the left side to the right side in the drawing as shown by the arrow, and the moving rake 4 is moved.
Through the circular movement of the rake 4, the bearing groove 4a (not shown) of the rake 4 lifts and conveys it as shown in FIG. 2 (2), and the traverser 11 is placed at the same height position as the fixed rake 5 as shown in FIG. , Raise in an overlapped manner and stop at the same position. The point (a) of the conveying material A located at the bottom of the bearing groove 5a in FIG. 2 (1) is unchanged even in the ascended position by the 1/2 pitch conveying shown in FIG. 2 (2). Next, as shown in FIG. 2 (3), while the moving rake 4 is moving to the descending conveying stroke of the remaining 1/2 pitch, the same rake 4 and the traverser 11 overlap each other, and the conveying material A is conveyed by the traverser 11. It contacts the inclined surface of the bearing groove 11a on the left side in the figure, and then the moving rake 4 reaches the descending stop position as shown in FIG. 2 (4).
The conveying material A left on the inclined surface of the bearing groove 11a rolls on the inclined surface and is supported between the inclined surface and the inclined surface of the bearing groove 5a of the fixed lake 5 on the right side in the figure. As a result of this movement, the transport material A is given a quarter rotation of the target rotation angle, as is apparent from the change in the position of point (a) in FIG. Then, as shown in FIG. 2 (5), the traverser 11 is moved from the position shown in FIG. 2 (4).
Is moved upward from the fixed lake 5 shown in the figure to move the conveying material A further from the right inclined surface of the bearing groove 5a of the fixed lake 5 to the right inclined surface of the bearing groove 11a of the traverser 11. / 4 rotations are given, and by these two rotations, the conveyance material A is given 1/2 rotation of the target rotation angle. From this traverser raised position, Fig. 2 (6)
In the illustrated example, the traverser 11 is slightly moved (back) in the direction opposite to the conveying direction of the conveying material A as shown in FIG.
(a) The point position is unchanged. Next, as shown in FIG. 2 (7), the traverser 11 is vertically lowered, so that the traverser 11 overlaps the fixed rake 5 during the downward movement, and the transport material A at the bottom of the bearing groove 11a of the traverser 11 is conveyed.
Partly contacts the inclined surface on the left side in the bearing groove 5a of the fixed lake 5 toward the same figure, and the traverser 11 returns to the lowest position as shown in FIG. While returning to the start position shown in), the bearing groove 11 of the traverser 11 is
The conveying material A on a rolls on the inclined surface on the left side of the bearing groove 5a in the fixed rake 5 toward the figure, is stopped at the bottom of the bearing groove 5a, and rolls along the inclined surface. , Material A
As is clear from the movement of the point (a) in the figure, the remaining half of the target rotation angle is applied and 100% of the target rotation angle is applied, so that the bending of the rod-shaped carrier A in the longitudinal direction is increased. The occurrence of can be suppressed by the same rotation.
In the example shown in the figure, the required rotation (remaining 1/2 rotation) is finally given by the movement progress from FIG. 2 (6) to FIG. 2 (8). ),
FIG. 2 shows the traverser 11 which has been lifted by supporting the conveying material A.
Without moving back like (6), as shown by the arrow, the same effect can be obtained by moving it forward from the raised position to the next fixed rake bearing groove 5a in the traveling direction, from the rolling mill side to the cooling floor. It is effective when the feeding time of the conveying material is fast (the interval is short). In any case, according to the participation of the rotary lake traversers 3 and 11 of the present invention, the rotation angle of the rod-shaped carrier A by one pitch is as follows. It is clear that the degree is as shown in Fig. 2 (9).
However, in the above equation, d represents the diameter of the rod-shaped carrier A, and α represents the angle of the inclined surface in the bearing groove 5a of the fixed rake 5.

Next, for the rod-shaped carrier A, which is the second object, the jump-carrying for varying the natural cooling time on the cooling floor can be performed as follows. By raising the traverser 11 descending to the illustrated C ₁ position to the illustrated C ₂ position by the elevating device D, a plurality of traversers 11 supported in the angular support groove 5a of the fixed lake 5 corresponding to the traverser 11 are supported. The bar-shaped carrier A can be scooped in the bearing groove 11a of the traverser 11 and moved upward without interfering with the fixed rake 5. Then, the traverser 11 is shown from its C ₂ position via the advancing / retreating device E. Move forward to C ₃ position,
Each rod-shaped carrier A on the bearing groove 11a is moved to the front position in the carrying direction, which jumps over the intermediate bearing groove 5a of the fixed rake 5, and then the traverser 11 at the position C ₃ is moved to the C position via the lifting device D. By lowering it to the _4th position, its supporting groove 11a
It is possible to transfer each of the rod-shaped carrier materials A therein to the bearing grooves 5a of the fixed rake 5 corresponding to the C ₃ position,
By returning the traverser 11 at the C ₄ position to the C ₁ position again, the residence time on the cooling floor of the plurality of rod-shaped conveying materials A supported in the supporting groove 5a of the fixed lake 5 can be arbitrarily changed. That is, the natural cooling time can be arbitrarily changed, and it is possible to shorten the cooling time from the first bearing groove 5a to the last bearing groove 5a by moving each bearing groove 5a of the fixed rake 5 sequentially. It is possible. This enables cutting under the optimum temperature adapted to the type and content of the rod-shaped conveying material A, and solves the conventional problems.

By interlocking, a pair of arms 1

A plurality of elevating rails 12, elevating devices D, and advancing / retreating devices E are arranged according to the number of traversers 11.

According to the above-described embodiment, when the traverser 11 formed under the length occupying a part of the entire length of the cooling floor in the transport direction is used as the rotating lake traverser, the traverser 11 may be any of the cooling floors. 2 (1) to 2 (8) (Fig. 2 (9)) at the position and in the state shown in Fig. 2 (1), and at that place, as described above in the section of the action.
It is possible to freely give the rotation to the rod-shaped carrier A as shown by the sequence of movements (including When the traverser 11 used as a rotary rake is required to have a small amount of vertical movement and horizontal movement, a hydraulic servo cylinder equipped with a servo valve, a synchro oscillator, etc. as a drive source is required to perform such a slight movement.

F indicates the groove center of the bearing groove 11a of the traverser 11, and as shown in the figure, there is a positional deviation of Δi ₃ shown in FIG. 2 (9) between them. Further, one side of the drawings showing the movement of the rod-shaped conveying material A, that is, the diagram shown in the right half of the drawing shows the movement of the traverser 11, which moves up and down as shown by the arrow lines. FIG. 3 (1) shows a rod-shaped carrier having a diameter d of 16φ, and FIG. 3 (2) shows a rod-shaped carrier of 25φ.
Fig. (3) shows the same 40φ, Fig. 3 (4) the same 60φ, and Fig. 3 (5) shows the case where rotational motion is given respectively, and the concrete numerical values attached to each figure As shown in

It is possible to give a required rotation angle to the rod-shaped conveying material A of each size over a wide range so that each rotation angle can be obtained. Further, in each drawing, the numerical value between E and F is a specific numerical value of Δi ₃ , which differs depending on the size of the conveying material, and its unit is mm. In addition, the values attached to the traverser operation diagram of each figure show the specific values of the vertical movement distance,
Similarly, the unit is mm.

In each of the above-mentioned embodiments, the operation of the rotary rake traverser 11 and the moving rake 4 is as described above with reference to FIG. 2 (including FIG. 2 (1) to FIG. 2 (6)). Since it is the same, a re-explanation is omitted here, but as is clear from the previous explanations, the conventional moving lake 4 and the fixed lake in which the carrier material supporting grooves 4a, 5a of the same shape and the same size are arranged in a row. At the intermediate position of 5, the traverser 11 having the support grooves 11a similar to the support grooves 4a and 5a arranged in a row is intervened so as to be able to move up and down, and during the rod-shaped transfer operation by the moving rake 4, the rotary lake traverser 11 participates, and By moving up and down and moving along the transport direction, and relaying and transferring the rod-shaped transport material A, the rod-shaped transport material A of each size is rotated about an axis of an arbitrary angle, and thereby the transport material A is generated. Bending in the longitudinal direction can be effectively suppressed Of.

Further, according to the above-described embodiment, when the traverser 11 is used as a fast-forwarding traverser, the rod-shaped carrier material A carried in by the run-in roller 1 passes through the alternate lift of the first lifter 2 and the second lifter 3. , And moving lake 4
Through the circular rotation movement of the fixed rake 5 into the first bearing groove 5a, and the subsequent rod-shaped conveying material A is sequentially loaded and taken in, and the leading rod-shaped conveying material A and the succeeding rod-shaped conveying material A are arranged in parallel in the bearing grooves 5a. In a similar manner, it will move forward in the conveying direction for one groove. If the number of the supporting grooves 5a of the fixed rake 5 is 90, the leading bar-shaped conveying material A is the last 90th supporting groove 5a when 90 bar-shaped conveying materials are taken in. And the rod-shaped carrier A exists in all the supporting grooves 5a. This transportation method is the same as the conventional one, and each natural cooling time of the rod-shaped transportation material A is the time required from the first bearing groove 5a to the last bearing groove 5a. Since the rapid traverser 11 is installed in the present invention, it is used as needed, and when the leading rod-shaped conveyer material A reaches a predetermined position, the traverser 11 is lifted to obtain the required number of rod-like conveyer materials A. Scooping on the bearing groove 11a, the traverser 11 is moved forward to a target position beyond the required number of grooves by a single operation of the traverser 11, and again before the aligning roller 7 shown in the figure, again on the bearing groove 5a of the fixed lake 5, a rod-shaped carrier material. A is moved down, and thereafter, it is moved by one pitch through the movement of the moving rake 4 and transferred onto the illustrated stacking conveyor 6, and the required number of stacks for each group is completed on the same conveyor 6. For example, one group of the rod-shaped conveyance materials A on the conveyor 6 is collectively conveyed onto the runout table 8 by using the traverser 11 in the example shown in the figure, and is sent to the cold cutting device side through the table 8 to measure the size. You will be disconnected. Bearing groove of fixed rake 5 by fast-forward traverser 11
The jumping distance of 5a can be selected to be large or small, which makes it easy to freely change the cooling time.

Further, as a modified embodiment of the present invention, it is possible to use the traverser 11 described above as a traverser 11 having a length over the entire length without having a length which occupies a part of the cooling floor. In this case, the fast-forward function is impossible, but the combination of the fixed rake 5, the moving rake 4, and the rotary rake traverser 11 allows the rotary conveyer type cooling floor to convey the convey material A while giving the rotary movement to the convey material A in the entire length of the cooling floor. It is also possible to use

(Effects of the Invention) According to the present invention, there are two problems, that is, when a rod-shaped conveying material is conveyed and cooled in a cooling floor, a bend occurs in the rod-shaped conveying material, and further, the cooling time of the rod-shaped conveying material is constant. , Which is extremely advantageous in that they can be solved simultaneously. That is, a traverser 11 in which bearing grooves 11a for the rod-shaped carrier A are arranged in the middle of the moving rake 4 and the fixed rake 5 in the conventional cooling floor equipment is vertically moved vertically and horizontally with respect to both lakes 4 and 5. The traverser 11 is used to automatically carry out permutation of each rod-shaped carrier A on the bearing groove 5a of the fixed rake 5 through the bearing groove 4a of the same rake 4 by the circular movement of the movable rake 4 so that it can move forward and backward. As a rotary rake traverse, by slightly moving up and down in the conveying movement and moving back and forth to intervene in synchronization, the carrier material A is relayed between the bearing groove 4a and the bearing groove 5a, and the bearing groove 11a and the bearing groove 5a. By giving the conveyor material A a rotation at an arbitrary angle by utilizing the groove inclined surfaces of the above, it is possible to suppress the one-way bending that occurs when the conveyor material A is conveyed. Large and small in size Without question, it can give without causing smooth and slippery effective rotational movement to bend prevention respectively over a very wide range,
This is extremely advantageous regardless of whether the material of the carrier material is hard or soft. As a result, a uniform carrier product having excellent quality can be obtained.

Furthermore, the cooling time on the cooling bed B of the rod-shaped carrier A can be arbitrarily selected and varied by using it as the fast-forwarding traverser 11 while the cooling time of the rod-shaped carrier A on the conventional cooling floor B is constant. It is extremely advantageous. That is, FIG. 4 shows a timing chart of normal cooling during transportation by moving all the supporting grooves of the conventional method, and FIG.
The figure is the same chart diagram using the fast-forward traverser 11 of the present invention. In both figures, the intake cycle T = 5 sec by the rakes 4 and 5 of the cooling bed B, the rake bearing groove N90 = 90.
This is a comparison under the condition that the number of grooves and the number of grooves to be conveyed by the fast-forwarding traverser 11 are N = 45, and the number of rod-shaped carrier materials A in one group is N = 20.
It takes 580 seconds from the carry-in to the cold cutting device, whereas the time required from the carry-in to the cold cutting device is 380 sec when the traverser 11 of FIG. As is clear from both figures, it is quite clear that the time spent on the fixed lake 5 occupies most of the time from the arrival to the start of cutting, and varying this time is the most reliable and This is an effective control of the cooling time, and is a control factor for obtaining the optimum cooling temperature for cutting, for example, and when the present invention cools the cooling bed sufficiently, it does not use the fast-forward traverser 11 and the moving rake 4 is used. When the groove feed means only with the fixed rake 5 is used, and when the cooling retention time is long in the above means and there is a possibility that the steel bar material etc. becomes too cold, the traverser 11 is skipped over the number of rake grooves corresponding to the required time which is not shortened. It should be transported by the machine to reach the cutting device at the optimum cooling temperature for cold cutting to improve the cut surface shape and prevent age cracking and bending after cutting. become. Of course, the present invention can be used in the case of treatments other than cutting, and is excellent as a solution to the problem of constant cooling time in this type of cooling bed.

Further, the carrying device according to the present invention has a relatively simple required configuration as a means for carrying out both of the above-mentioned means, and can be easily carried out in a conventional cooling floor facility, and has a scale of a cooling floor. Accordingly, it suffices to intervene the rotary rake and fast-forward traverser 11 of a required length, and it is necessary to set the necessary positional deviation of Δi ₃ between the fixed rake 5 and the traverser 11 for one-pitch transport without any particular bending. Depending on the diameter of the rod-shaped conveying material A to be set, an appropriate positional deviation can be set by moving the traverser 11 back and forth horizontally. Therefore, no special complicated movement is necessary for the traverser 11, and only the position and timing are required. Considering the above, it is possible to obtain a movement that does not cause any slippage, there is no risk of scratches on the surface of the rod-shaped conveying material, and smooth conveyance can be realized regardless of whether the material is hard or soft. .
