Next, several examples of the swing movement of the upper conveyor 10 will be described.

Figures 4a to 4c show the first position (Figure 4a), the second position (Figure 4b), and the third position (Figure 4c) of the first example of the swing movement of the upper conveyor 10. ) Is a schematic front view, and FIG. 5 is a view showing the conveyor 10 superimposed on the first position, the second position, and the third position. By the swinging motion moving from the first position to the third position, the pressing position of the cluster D on the lower bottom surface 10fa of the arc of the upper conveyor belt 10f is moved from the upstream side to the downstream side. Generally speaking, at a certain point in time, the pressing position is near the lower bottom surface 10fa of the arc where the distance from the lower conveyor 4 is the smallest. Therefore, the pressing position is represented by the lowermost position 24 of the lower bottom surface 10fa of the arc, and is displayed with a black circle. In the first example, the trajectory 26 at the lowest position 24 is a straight line, and the vertical distance between the trajectory 26 and the reference line 20 decreases from the upstream side to the downstream side (please refer to Fig. 5). That is, when the pressing point moves from the upstream side to the downstream side, the distance between the upper conveyor 10 and the lower conveyor 4 located at the pressing point becomes smaller. Next, perform a swing motion moving from the third position to the first position in the opposite motion.

Figures 6a to 6c show the first position (figure 6a), the second position (figure 6b), and the third position (figure 6c) of the second example of the swing movement of the upper conveyor 10 The schematic front view, and Fig. 7 is a view showing the conveyor 10 superimposed on the first position, the second position, and the third position. By the swinging motion moving from the first position to the third position, the pressing position of the cluster D on the lower bottom surface 10fa of the arc of the upper conveyor belt 10f is moved from the upstream side to the downstream side. Generally speaking, at a certain point in time, the pressing position is near the lower bottom surface 10fa of the arc where the distance from the lower conveyor 4 is the smallest. Therefore, the pressing position is represented by the lowermost position 24 of the lower bottom surface 10fa of the arc, and is displayed with a black circle. In the second example, the trajectory 26 at the lowest position 24 is a straight line, and the vertical distance between the trajectory 26 and the reference line 20 is constant from the upstream side to the downstream side (please refer to Fig. 7). That is, when the pressing point moves from the upstream side to the downstream side, the distance between the conveyor 10 above the pressing point and the lower conveyor 4 is constant. Next, perform a swing motion moving from the third position to the first position in the opposite motion.

Figures 8a to 8b are schematic front views showing the fourth position (Figure 8a) and the fifth position (Figure 8b) of the third example of the swing motion of the upper conveyor 10. In the third example, the swing movement from the first position to the third position is the same as the first or second example. Next, the upper conveyor 10 is raised, and the lowermost position 24 of the lower bottom surface 10fa of the arc is moved away from the raw mass D by the swing motion toward the fourth position and the fifth position, and the lowermost position 24 moves from the downstream side to the upstream side. Next, the upper conveyor 10 is lowered and returned to the first position.

Next, the operation of the corpus extension device 1 will be described.

The first lower conveyor 6 is operated at a speed V1, and the second lower conveyor 8 is operated at a speed V2 faster than the speed V1. In addition, the upper conveyor belt 10f is driven at the same speed with respect to the lower conveyors 6, 8. Specifically, when the mass D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the first lower conveyor 6, the speed of the upper conveyor belt 10f is set to be the same as that of the first lower conveyor 6. The speed V1 of the machine 6 is the same speed. Also, when the mass D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the second lower conveyor 8, the speed of the upper conveyor belt 10f is set to be the same as that of the second lower conveyor 8. The speed V2 of 8 is the same speed. The switching of the speed of the upper conveyor belt 10f is performed when, for example, the lowermost position 24 comes between the first lower conveyor 6 and the second lower conveyor 8.

In addition, the swing movement of the upper conveyor 10 is performed. The swing speed, that is, the moving speed in the flow direction F of the lowermost position 24 of the lower bottom surface 10fa of the arc, is determined to be faster than the speed V2 of the second lower conveyor 8 at least. Assuming that the moving speed of the lowermost position 24 is the same as the speed of the lower conveyor 4, the location of the cluster D pressed by the upper conveyor 10 (imaginary large-diameter roller 22) remains unchanged. By accelerating the moving speed of the lowermost position 24, the imaginary large-diameter roller 22 rolls to press a wide range of the raw mass D, which improves the extension efficiency.

In the case of the swing movement of the first example shown in Fig. 4a to Fig. 4c and Fig. 5, when the upper conveyor 10 swings from the first position to the second position, the upper conveyor 10 and the first lower conveyor 6 are The distance between them becomes smaller, so the cluster D is effectively extended. In addition, when the upper conveyor 10 swings from the first position to the second position, the lowermost position 24 moves from above the first lower conveyor 6 operating at speed V1 to the second lower conveyor 8 operating at speed V2 Above, since the speed of the upper conveyor belt 10f of the upper conveyor 10 is switched from V1 to V2, the cluster D is stretched toward the flow direction F to be efficiently extended. When the upper conveyor 10 swings from the second position to the third position, since the distance between the upper conveyor 10 and the second lower conveyor 8 becomes smaller, the cluster D is effectively extended. On the other hand, when the upper conveyor 10 returns from the third position to the first position, it will slightly push the raw mass D back to the upstream side. In addition, since the distance between the upper conveyor 10 and the first lower conveyor 6 becomes larger, the cluster is not stretched much. By repeating the above-mentioned operations, the cluster expansion device 1 conveys and expands the cluster D between the upper conveyor 10 and the lower conveyors 6, 8 at the same time.

When the upper conveyor 10 swings from the first position to the second position in the case of the swing movement of the second example shown in Fig. 6a to Fig. 6c and Fig. 7, the difference between the upper conveyor 10 and the first lower conveyor 6 The distance between is constant, and the cluster D is extended corresponding to this distance. In addition, when the upper conveyor 10 swings from the first position to the second position, the lowermost position 24 moves from above the first lower conveyor 6 operating at speed V1 to the second lower conveyor 8 operating at speed V2 Above, since the speed of the upper conveyor belt 10f of the upper conveyor 10 is switched from V1 to V2, the cluster D is stretched toward the flow direction F to be efficiently extended. When the upper conveyor 10 swings from the second position to the third position, the distance between the upper conveyor 10 and the second lower conveyor 8 is constant, and the cluster D is extended corresponding to the distance. When returning from the third position to the first position, there will be a slight effect of pressing the raw mass D back to the upstream side, but the raw mass D will be extended corresponding to the distance between the upper conveyor 10 and the second lower conveyor 8. . By repeating the above-mentioned operations, the cluster expansion device 1 conveys and expands the cluster D between the upper conveyor 10 and the lower conveyors 6, 8 at the same time.

In the case of the swing movement of the third example, when the upper conveyor 10 swings from the first position to the third position, it is the same as the first or second example. When the upper conveyor 10 is raised and swung from the 4th position to the 5th position, since the upper conveyor belt 10f of the upper conveyor 10 leaves the cluster D, the cluster D is not stretched. On the other hand, unlike the first and second cases, there is no effect of pressing the raw mass D back to the upstream side. By repeating the above-mentioned operations, the cluster expansion device 1 conveys and expands the cluster D between the upper conveyor 10 and the lower conveyors 6, 8 at the same time.

Next, referring to Fig. 9, the cluster spreading device 30 according to the second embodiment of the cluster spreading device of the present invention will be described. The cluster spreading device 30 has the same configuration as the cluster spreading device 1 of the first embodiment except for the first lower conveyor 32. Therefore, in the second embodiment, components other than the first lower conveyor 32 are assigned the same reference numerals as in the first embodiment, and their description is omitted.

The first lower conveyor 32 is provided with a small diameter entrance roller 32a, a conveyor plate 32b, and a small diameter exit roller 32c, a driving roller 32d, and a revolving roller 32a, 32c, 32d The first lower conveyor belt 32e and the drive motor 32f connected to the drive roller 32d. The entrance roller 32a, the exit roller 32c, and the drive roller 32d. The first lower conveyor belt 32e in between is arranged at an inclination angle α with respect to the reference line 20; the conveyor plate 32b is The angle α supports the first lower conveyor belt 32e located between the entrance roller 32a and the exit roller 32c. The diameter of the entrance roller 6a and the exit roller 6c is, for example, 10 to 20 mm. The first lower conveyor belt 6e is made of urethane, for example.

The swing motion of the upper conveyor 10 is the same as in the first embodiment. The oscillating motion of the first example is shown in Figures 10a to 10c instead of Figures 4a to 4c; the oscillating motion of the second example is shown in Figures 11a to 11a instead of Figures 6a to 6c. Figure 11c, and its description is omitted. Regarding the swing motion of the third example, the description is omitted by referring to Figs. 8a to 8b.

Next, the operation of the corpus extension device 30 will be described.

The first lower conveyor 32 is operated at a speed V1, and the second lower conveyor 8 is operated at a speed V2 faster than the speed V1. Moreover, the upper conveyor belt 10f is driven at the same speed with respect to the lower conveyors 32 and 8. Specifically, when the pellet D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the first lower conveyor 32, the speed of the upper conveyor belt 10f is set to be the same as that of the first lower conveyor 32. The speed V1 of the machine 32 is the same speed. Also, when the raw mass D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the second lower conveyor 8, the speed of the upper conveyor 10 is set to be the same as that of the second lower conveyor 8. The speed V2 is the same speed. The speed of the upper conveyor belt 10f is switched, for example, when the lowermost position 24 is between the first lower conveyor 32 and the second lower conveyor 8.

In addition, the swing movement of the upper conveyor 10 is performed. The swing speed, that is, the moving speed in the flow direction F of the lowermost position 24 of the lower bottom surface 10fa of the arc, is determined so as to be faster than the speed of the second lower conveyor 8 at least. Assuming that the moving speed of the lowermost position 24 is the same as the speed of the lower conveyor 4, the location of the cluster D pressed by the upper conveyor 10 (imaginary large-diameter roller 22) remains unchanged. By accelerating the moving speed of the lowermost position 24, the rolling effect of the imaginary large-diameter roller 22 can be used to press a wide range of the pellet D, which improves the extension efficiency.

When the upper conveyor 10 swings from the first position to the second position in the case of the swing movement of the first example shown in Fig. 10a to Fig. 10c, due to the distance between the upper conveyor 10 and the first lower conveyor 32 As it becomes smaller, the so-called group D is effectively extended. In addition, when the upper conveyor 10 swings from the first position to the second position, the lowermost position 24 moves from above the first lower conveyor 32 operating at the speed V1 to the second lower conveyor 8 operating at the speed V2. Above, since the speed of the upper conveyor belt 10f of the upper conveyor 10 is switched from V1 to V2, the pellet D is stretched toward the flow direction F to be efficiently extended. When the upper conveyor 10 swings from the second position to the third position, since the distance between the upper conveyor 10 and the second lower conveyor 8 becomes smaller, the cluster D is effectively extended. On the other hand, when the upper conveyor 10 returns from the third position to the first position, it will slightly push the raw mass D back to the upstream side. In addition, since the distance between the upper conveyor 10 and the first lower conveyor 32 becomes larger, the cluster is not stretched much. By repeating the above-mentioned operations, the cluster expansion device 1 conveys and expands the cluster D between the upper conveyor 10 and the lower conveyors 32 and 8.

In the case of the swing movement of the second example shown in Figures 11a to 11c, when the upper conveyor 10 swings from the first position to the second position, due to the inclination of the first lower conveyor 32, the upper conveyor 10 The distance from the first lower conveyor 32 becomes smaller, so the cluster D is efficiently extended. In addition, when the upper conveyor 10 swings from the first position to the second position, the lowermost position 24 moves from above the first lower conveyor 32 operating at the speed V1 to the second lower conveyor 8 operating at the speed V2. Above, since the speed of the upper conveyor belt 10f of the upper conveyor 10 is switched from V1 to V2, the pellet D is stretched toward the flow direction F to be efficiently extended. When the upper conveyor 10 swings from the second position to the third position, the distance between the upper conveyor 10 and the second lower conveyor 8 is constant, and the cluster D is extended corresponding to the distance. When the upper conveyor 10 returns from the third position to the second position, it will slightly push the raw mass D back to the upstream side, but the raw mass will correspond to the distance between the upper conveyor 10 and the second lower conveyor 8. And be stretched. In addition, when the upper conveyor 10 returns to the first position from the second position, it will slightly push the raw mass D back to the upstream side. In addition, since the distance between the upper conveyor 10 and the first lower conveyor 32 becomes larger, the cluster is not stretched much. By repeating the above-mentioned operations, the cluster expansion device 1 conveys and expands the cluster D between the upper conveyor 10 and the lower conveyors 32 and 8.

In the case of the swing movement of the third example, when the upper conveyor 10 swings from the first position to the third position, it is the same as the first or second example. When the upper conveyor 10 is raised and swung from the 4th position to the 5th position, since the upper conveyor belt 10f of the upper conveyor 10 leaves the cluster D, the cluster D is not stretched. On the other hand, unlike the first and second cases, there is no effect of pressing the raw mass D back to the upstream side. By repeating the above-mentioned operations, the cluster expansion device 1 conveys and expands the cluster D between the upper conveyor 10 and the lower conveyors 32 and 8.

Next, with reference to Figs. 12 and 13, the corpus expansion device 40 according to the third embodiment of the corpus expansion device of the present invention will be described. The cluster extension device 40 has the same configuration as the cluster extension device 1 of the first embodiment, except that the swing mechanism 14 is changed to a sliding mechanism. Therefore, in the third embodiment, components other than the sliding mechanism are denoted by the same reference numerals as in the first embodiment, and their description is omitted.

As shown in FIGS. 12 and 13, the cluster expansion device 40 includes a sliding mechanism 44 that slides the upper conveyor 10.

Next, an example of the sliding movement of the upper conveyor 10 will be described.

Figures 14a to 14f are the first position (Figure 14a), the second position (Figure 14b), the third position (Figure 14c), and the fourth position showing examples of sliding movement of the upper conveyor 10 (Figure 14d), a schematic front view of the fifth position (Figure 14e), and the sixth position (Figure 14f). By the sliding motion moving from the first position to the fourth position, the pressing position of the raw mass D contacted by the lower bottom surface 10fa of the arc of the upper conveyor belt 10f moves from the upstream side to the downstream side. The pressing place is generally speaking, at a certain point in time, near the bottom surface 10fa under the arc where the distance from the lower conveyor 4 is the smallest. Therefore, the pressing position is represented by the lowermost position 24 of the lower bottom surface 10fa of the arc, and is displayed with a black circle. In this example, the trajectory 26 of the lowest position 24 is a straight line, and the vertical distance between the trajectory 26 and the reference line 20 is constant from the upstream side to the downstream side. That is, when the pressing point moves from the upstream side to the downstream side, the distance between the upper conveyor 10 and the lower conveyor 4 located at the pressing point is constant. Next, in the opposite operation, a sliding movement is performed to move from the fourth position to the sixth position and from the sixth position to the first position.

Next, the operation of the corpus extension device 40 will be described.

The first lower conveyor 6 is operated at a speed V1, and the second lower conveyor 8 is operated at a speed V2 faster than the speed V1. In addition, the upper conveyor 10 is slid from the first position to the fourth position (from the upstream side to the downstream side) with respect to the main frame 2 at a sliding speed V3, and then the upper conveyor 10 is moved from the fourth position to the sixth position and It slides with respect to the main frame 2 at a sliding speed V3 from the sixth position toward the first position (the downstream side is from the upstream side).

The upper conveyor belt 10f is driven at the same speed with respect to the lower conveyors 6, 8. Specifically, when the sliding of the upper conveyor 10 stops, and the raw mass D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the first lower conveyor 6 (the first position in Fig. 14a) ), the speed of the upper conveyor belt 10f is set to the same speed as the speed V1 of the first lower conveyor 6. When the upper conveyor 10 slides from the upstream side to the downstream side at a speed of V3, the cluster D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the first lower conveyor 6 (Figure 14b) The second position), the speed V4 of the upper conveyor belt 10f relative to the upper conveyor 10 is made V1-V3. When the upper conveyor 10 slides from the upstream side to the downstream side at a speed of V3, the raw mass D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the second lower conveyor 8 (Figure 14c) 3rd position), the speed V5 of the upper conveyor belt 10f with respect to the upper conveyor 10 is made V2-V3. When the sliding of the upper conveyor 10 stops and the cluster D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to the position above the second lower conveyor 8 (the fourth position in Fig. 14d), the upper The speed of the conveyor belt 10f is the same as the speed V2 of the second lower conveyor 8. When the upper conveyor 10 slides from the downstream side to the upstream side at a speed of V3, the raw mass D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the second lower conveyor 8 (Figure 14e) 5th position), the speed V6 of the upper conveyor belt 10f with respect to the upper conveyor 10 is made V2+V3. When the upper conveyor 10 slides from the downstream side to the upstream side at a speed of V3, the cluster D pressed by the lower bottom surface 10fa of the upper conveyor belt 10f mainly comes to a position above the first lower conveyor 6 (Figure 14f) The sixth position) is set to V1+V3 relative to the speed V7 of the conveyor belt 10f on the upper conveyor 10. The switching of the speed of the upper conveyor belt 10f during the sliding of the upper conveyor 10, for example, at the lowermost position 24 of the lower bottom surface 10fa of the upper conveyor belt 10f, to the first lower conveyor 6 and the second lower conveyor 8 In between.

The sliding speed V3 of the upper conveyor 10, that is, the moving speed in the flow direction F of the lowermost position 24 of the lower bottom surface 10fa of the arc, is set at least faster than the speed V2 of the second lower conveyor 8. Assuming that the moving speed of the lowermost position 24 is the same as the speed of the lower conveyor 4, the location of the cluster D pressed by the upper conveyor 10 (imaginary large-diameter roller 22) remains unchanged. By accelerating the moving speed of the lowermost position 24, the imaginary large-diameter roller 22 can roll-like action to press a wide range of the cluster D, so that the extension efficiency is improved.

When the upper conveyor 10 slides from the first position to the second position, the distance between the upper conveyor 10 and the first lower conveyor 6 is constant, and the cluster D is extended corresponding to the distance. When the upper conveyor 10 slides from the second position to the third position, due to the lowermost position 24, it moves from above the first lower conveyor 6 operating at speed V1 to above the second lower conveyor 8 operating at speed V2 , The speed of the conveyor belt 10f on the upper conveyor 10 is switched from V4 to V5, so the cluster D is stretched toward the flow direction F to be efficiently extended. When the upper conveyor 10 slides from the third position to the fourth position, the distance between the upper conveyor 10 and the second lower conveyor 8 is constant, and the cluster D is extended corresponding to the distance. When returning from the fourth position to the first position, there will be a slight effect of pressing the raw mass D back to the upstream side, but the raw mass D is extended corresponding to the distance between the upper conveyor 10 and the lower conveyors 6, 8. Therefore, the cluster spreading device 1 spreads the cluster D between the upper conveyor 10 and the lower conveyors 6 and 8 while conveying it.

If a swing mechanism is used, the space of the upper conveyor 10 can be reduced, and the swing motion can be set relatively freely, but the mechanism itself is more complicated. If a sliding mechanism is used, the space of the upper conveyor 10 will become longer in the flow direction, the degree of freedom of sliding movement is small, and the mechanism itself is relatively simple.

Next, referring to Fig. 15, it will be described that it is a cluster spreading device 50 according to the fourth embodiment of the cluster spreading device of the present invention. The raw mass spreading device 50, in addition to the upper roller unit 52 of the upper conveyor 10, the lower roller unit 54 of the second lower conveyor 8, and the raw mass pressing roller 56, is provided with the same raw material as the first embodiment. The group spreading device 1 has the same configuration. Therefore, in the fourth embodiment, components other than the upper roller unit 52, the lower roller unit 54, and the dough pressing roller 56 are assigned the same reference numerals as in the first embodiment, and the description is omitted.

The raw mass spreading device 50 is provided with an upper roller unit 52 instead of the upper conveyor plate 10c of the upper conveyor 10 of the raw mass spreading device 1 of the first embodiment. The upper roller unit 52 of the upper conveyor 10 is equipped with a large number of small-diameter rollers 52a; a large number of small-diameter rollers 52a are used to support the upper conveyor belt 10f, so that the upper conveyor belt 10f has an upstream The side faces the lower bottom surface 10fa of the arc driven on the downstream side. The upper roller unit 52 further includes: a shaft 52b supporting a large number of small diameter rollers 52a, a bracket 52c supporting a large number of shafts 52b, and a base 52d on which a large number of brackets are attached. The outer diameter of the small-diameter roller 52a is, for example, 30 to 40 mm. In order to increase the arrangement density of the small-diameter rollers 52a, it is preferable to arrange the small-diameter rollers 52a in a staggered arrangement (please refer to Fig. 16).

In addition, the cluster spreading device 50 is provided with a lower roller unit 54 instead of the entrance roller 8a and the conveyor plate 8b of the second lower conveyor 8 of the cluster spreading device 1 of the first embodiment. The lower roller unit 54 of the second lower conveyor 8 includes an entrance plate 54a having a small diameter entrance roller, a large number of small diameter rollers 54b, and an intermediate plate 54c. The inlet plate 54a, the small diameter roller 54b, the intermediate plate 54c, and the outlet roller 8c support the second lower conveyor belt 8e located in between, and the second lower conveyor belt 8e is linear ( Horizontal) configuration. The lower roller unit 54 further includes: a plurality of shafts 54d for supporting the small diameter roller 54b, a bracket 54e for supporting the plurality of shafts 54d, and a base 54f on which the plurality of brackets are attached. The outer diameter of the small-diameter roller 54b is, for example, 30 to 40 mm. In order to increase the arrangement density of the small-diameter rollers 54b, similarly to the upper roller unit 52, it is preferable to arrange the small-diameter rollers 54b in a staggered arrangement (illustration omitted).

In addition, the cluster extension device 50 is provided with a cluster pressing roller 56 for pressing the cluster D entered on the upper conveyor 10. The raw dough pressing roller 56 is arranged above the first lower conveyor 6 and on the upstream side of the upper conveyor 10. The raw ball pressing roller 56 is installed on the main frame 2 in a manner that the height relative to the first lower conveyor 6 can be adjusted. In addition, the raw ball pressing roller 56 is driven by the motor 56a in a manner that the rotation speed can be adjusted.

Next, the operation of the corpus extension device 50 will be described.

The first lower conveyor 6 is operated at a speed V1, and the second lower conveyor 8 is operated at a speed V2 faster than the speed V1. The raw dough pressing roller 56 is operated at a peripheral speed slightly faster than the speed V1 of the first lower conveyor 8 to prevent the raw dough D from staying in front of the raw dough pressing roller 56. In addition, the upper conveyor 10 is driven at a speed V3 faster than the speed V1 of the first lower conveyor 6. In addition, the speed V2 of the second lower conveyor 8 is set to be faster than the speed V3 of the upper conveyor 10. The upper roller unit 52 of the upper conveyor 10 and the lower roller unit 54 of the second lower conveyor 8 prevent sliding of the driving rollers 10e, 8d of the upper conveyor belt 10f and the second lower conveyor belt 8e , And make the extension of Sheng Tuan D improve.

In addition, there are many places where the lower bottom surface 10fa of the arc of the upper conveyor belt 10f is supported by a large number of small-diameter rollers 54b and where there is no support. Therefore, when the cluster D is pressed, the upper conveyor belt The lower bottom surface 10fa of 10f is formed with projections and depressions to prevent sliding of the cluster D on the arcuate bottom surface 10fa of the conveyor belt 10f, and to increase the extension of the cluster D. In addition, by forming irregularities on the surface of the lower bottom surface 10fa of the arc of the conveyor belt 10f, the cluster D pressed by the majority of the convex portions can escape to the adjacent concave portion, and the extension of the cluster is increased.

In addition, the swing movement of the upper conveyor 10 is performed. The swing speed, that is, the moving speed in the flow direction F of the lowermost position 24 of the lower bottom surface 10fa of the arc, is set to approximately 8-17 times the speed V2 of the second lower conveyor 8. By making the imaginary large-diameter roller 22 act like a rolling, it presses a wide range of the raw mass D, so that the spreading efficiency is improved. In addition, by accelerating the swing speed of the upper conveyor 10, the unevenness of the surface of the cluster D generated by the swing motion can be reduced. Since the speed V3 of the upper conveyor 10 is constant, the speed switching of the upper conveyor 10 performed in the first to third embodiments can be omitted.

Figures 17a to 17c show the first position (figure 17a), the second position (figure 17b), and the third position of the same swing motion as shown in figures 4a to 4c (Figure 17c). When the upper conveyor 10 swings from the first position to the second position, since the distance between the upper conveyor 10 and the first lower conveyor 6 becomes smaller, the expansion of the cluster D of the imaginary large-diameter roller 22 can be achieved. Do it efficiently. Furthermore, since the speed V3 of the upper conveyor 10 is faster than the speed V1 of the first lower conveyor 6, the raw mass D (especially the upper side) between the upper conveyor 10 and the raw mass pressing roller 56 is directed to flow Stretching in the direction F, the cluster D is effectively stretched. When the upper conveyor 10 swings from the second position to the third position, since the distance between the upper conveyor 10 and the second lower conveyor 8 becomes smaller, the imaginary large-diameter roller 22 of the cluster D Stretching can be carried out efficiently. Furthermore, since the speed V2 of the second lower conveyor 8 is faster than the speed V3 of the upper conveyor 10, the raw mass D (especially the lower side) between the upper conveyor 10 and the raw mass pressing roller 56 is directed toward The flow direction F is stretched, and the cluster D is effectively stretched. That is, the extension of the upper and lower sides of the cluster D is performed alternately. In addition, when the upper conveyor 10 returns to the first position from the third position, it has the effect of pressing the raw mass D back to the upstream side, and has the effect of pressing and releasing the gas in the raw mass D. On the other hand, since the distance between the upper conveyor 10 and the first lower conveyor 6 becomes larger, the extension of the cluster D by the imaginary large-diameter roller 22 is not obvious, but the upper conveyor 10 and the cluster The stretching between the pressing rollers 56 will proceed, so the cluster D is effectively stretched. Repeating the above-mentioned actions, the cluster extension device 50 extends the cluster D between the upper conveyor 10 and the lower conveyors 6, 8 while conveying it.

The above-mentioned convex wheel shape may also be a combination of a plurality of arcs, curves and/or straight lines.
