Abstract

PURPOSE:To prevent the increase of the load from a belt-like semi-finished product in guide bodies and to prevent the damage of a pelletizer by releasing the locking action of a locking means by the detection signal of a detecting means. CONSTITUTION:A limit switch 37 is attached to a cylindrical body 31. The switch 37 is normally off but when the belt-like semi-finished product C pushes an actuating shaft 32 to the prescribed extent or above by overcoming the energizing force of a spring 35, the switch 37 turns on. The signal indicating the generation of the clogging by the product C is outputted to each cylinder via an electrical circuit when both the switches 37 in the means 14 turn on. An recessed member for engagement is thereby retreated to release the locking between the guide plates.

In the industrial field, etc., it relates to a compression roll type granulator that forms various powder raw materials into briquettes of desired shape. It relates to a processing device.

(Prior Art) Conventionally, there is a device configured to form granular material into briquettes of a desired shape, for example, as disclosed in Japanese Patent Application Laid-open No. 59-153599.

That is, a pair of forming rolls with concave pockets that rotate in opposite directions are provided, and the powder material is continuously sandwiched between these forming rolls and compressed to form a band-like intermediate product made of briquettes interconnected by ribs. be done. Further, a rotary hammer is provided which strikes this belt-shaped intermediate product at predetermined intervals and breaks the rib portion to separate it into individual pieces.

However, in the above configuration, during the briquette manufacturing process, the hammer hits the shell formed on the surface of the briquette, so the impact force is transmitted to the inside of the briquette, causing the briquette itself to break without breaking the rib part. There is a risk.

Therefore, a device has been proposed that divides the intermediate belt-shaped product and forms individual briquettes without applying impact force.
This includes the one shown in FIG.

The upper guide 16 includes guide plates 19 and 19 which are a pair of guide bodies that face each other across the belt-shaped intermediate product C in the thickness T direction thereof.
' Consists of '. These guide plates 19 and 19' have a cross section H
shape, and the grooves face each other so that both guide plates 1
A guide hole is formed between 9 and 19'. Further, a storage cage 21 formed in a downwardly convex semicircular shape when viewed from the front is provided so as to surround both guide plates 19 and 19'.

20.20 is Laerte, Ko (7) Leh Jl/20, 2
0 extends in the horizontal direction, and the storage cage 21 is movably supported on this rail 20.20 via rollers 23.

The accommodation cage 21 is divided in the direction of the thickness T of the belt-shaped intermediate product C, with the position where the belt-shaped intermediate product C passes as a boundary. These divided cages 21a and 21a each consist of a frame member 21b and a wire mesh 21c that is attached to these frame members 21b and constitutes the outer shell of the divided cage 21a, and both frame members 21b and 21b are screwed together by a pole 21d. It's stopped.

The upper ends of each of the guide plates 19, 19' are pivotally supported by a pivot shaft 21e on each of the divided cages 21a, and these can be freely expanded by rotating the guide plates 19, 19'. That is, when a misroll occurs within the guide means 13, both the guide plates 19, 19'
is expanded, and this belt-shaped intermediate product C is accommodated in the storage cage 21.

A locking means 24 is provided for releasably locking the guide plates 19 and 19' in a hanging position when guiding the band-shaped intermediate product C toward the intermediate guide 17 side.

In FIGS. 5 and 6, the locking means 24 has a pair of air cylinders 25, 25 positioned to sandwich the guide plate 19, 19'. Each air cylinder 25 is removably screwed across the frame members 21b, 21b of the redivided cages 21a, 21a, and these two frame members 21
The piston rod 25a is inserted between b and 21b,
A U-shaped engagement concave member 26 is attached to the protruding end of the piston rod 25a. In addition, corresponding to the engagement concave member 26, engagement protrusions 19a, 19a are formed on both sides of the guide plates 19 and 19', respectively.

Then, when the air cylinder 25 extends with the guide plates 19.19' in the hanging position, the engagement concave member 26 pinches the re-engagement protrusions 19a, 19a, thereby causing the guide plates 19.19' to is locked. On the other hand, the contracting action of the air cylinder 25 causes the engagement recessed member 26 to move back and release the locked state, whereby both guide plates 1
9°19' can be expanded.

Further, an opening 21f through which the band-shaped intermediate product C passes is formed in the lower part of the storage cage 21, and this opening 21
A pair of lid members 27.27 are provided to open and close f. The end of each of these lid members 27 on the side far from the band-shaped intermediate product C is pivoted to the storage cage 21 via a hinge 28,
Further, the end portion on the side closer to the band-shaped intermediate product C is connected to the frame member 21b by a stopper 29. Then, when the opening 21f is opened by rotating the lid member 27, the strip-shaped intermediate product C accommodated in the storage cage 21 due to misrolling can be discharged from the opening 2Lf.

Further, when the band-shaped intermediate product C becomes clogged in the guide means 13 due to a misroll, a pair of detection means 14.14 detects the misroll by receiving a pressing force of a predetermined amount or more from the band-like intermediate product C. provided. These detection means 14.14 are attached to the upper end of the intermediate guide 17, sandwiching the band-shaped intermediate product C in the thickness direction T, and in the vicinity of these detection means 14.14, the horizontal direction of the intermediate guide 17 is The gap is the thickness T of the strip-shaped intermediate product C as above.
It is said to be more than twice that of the previous year.

The detection means 14 will be explained based on FIGS. 1 and 7. A cylindrical body 31 having a horizontal axis is screwed to the intermediate guide 17. An operating shaft 32 is fitted into the cylindrical body 31 so as to be slidable in the axial direction, and the end of the operating shaft 32 on the side of the band-shaped intermediate product C has a pressed portion that can come into contact with the band-shaped intermediate product C. A barrel sphere 33 is attached.

This sphere 33 is connected to the through hole 1 formed in the intermediate guide 17.
It projects into the intermediate guide 17 through 7a. This spherical body 33 is urged toward the belt-shaped intermediate product C by a spring 35 installed between the operating shaft 32 and the cylindrical main body 31.

On the other hand, a tapered surface is formed on the other end side of the operating shaft 32, and a limit switch 37 that comes into contact with this tapered surface
is attached to the cylindrical body 31.

This limit switch 37 is OFF in the normal state, but when the band-shaped intermediate product C pushes the operating shaft 32 by a predetermined amount or more against the biasing force of the spring 35, this pushing force causes the limit switch 37 to be turned off. Turn it ON. In this case, when each limit switch 37 in the detection means 14.14 is turned ON, a signal indicating that a clogging phenomenon has occurred due to the band-shaped intermediate product C is outputted to each of the air cylinders 25 via the electric circuit 38, As a result, the engaging concave member 26 retreats, and the locked state of the guide plates 19 and 19' described above is released.

Note that the cylindrical body 31 is formed into a double pipe, and cooling water is passed through the inside thereof through nozzles 40 and 40, thereby cooling the detection means 14.

In addition, as shown in FIGS. 1 and 3, one guide plate 1
9' with a pressing force of more than a predetermined amount from the belt-shaped intermediate product C,
A detection means 43 for outputting a signal is provided, and this detection means 43 has the same structure as the detection means 14 and is attached to the cylindrical body 31. It has an operating shaft 32, a limit switch 37, etc. The end of this actuating shaft 32 is inserted between both guide plates 19.19', and this detection means 43 is also connected to the air cylinder 25.25 via the electrical circuit 38. When the limit switch 37 of this detecting means 43 is turned on, the air cylinders 25, 25 operate and the guide plate 19.
19' are unlocked.

In the granulator A having the above configuration, the operation during operation will be explained based on FIGS. 8 to 11 and FIG. 1.

FIG. 8 shows the state immediately after the start of operation. in this case,
The lower end of the strip-shaped intermediate product C formed by the compacting rolls 7, 7' is usually bent, and therefore, it is pressed against one of the detection means 14, 14 on one side of the detection means 14, 14. , the limit switch 37 of this detection means 14 may be turned on. In this case, since the limit switch 37 of only one of the detection means 14 is turned on, a signal indicating that a clogging phenomenon has occurred due to the belt-shaped intermediate product C is not outputted from the electric circuit 38. In this case, in the vicinity of the detection means 14, the gap between the intermediate guides 17 is the thickness T of the strip-shaped intermediate product C, as described above.
Since the detection means 1 is secured more than twice as much as the
4.14 both being turned ON is more reliably prevented, and therefore, the molding of the band-shaped intermediate product C is continued.

FIG. 9 shows a normal operating condition. In this case, the limit switches 37 of each detection means 14.43 are both OFF.
Then, the strip-shaped intermediate product C is continuously divided between the dividing rolls 10 and 10, and the briquettes B are formed normally.

FIG. 1O shows a state in which a misroll occurs within the intermediate guide 17. In this case, as the band-shaped intermediate product C is bent and jammed within the intermediate guide 17, the sphere 33 of each detection means 14 is pressed by the band-shaped intermediate product C, and the limit switch 37 of each detection means 14 is pressed. are both turned on. In this case, a signal is output from the electric circuit 38 connected to these limit switches 37. Once the misroll condition occurs, the electric circuit 38 is electrically self-maintained to output the signal.

The components of the granulator A are operated by the output signal from the electric circuit 38 as described below.

In FIG. 11, first, the reducing furnace discharge port (not shown) connected to the supply port 3 is closed, and the supply of the powder M is stopped. Further, the locked state of the guide plates 19 and 19' is released, allowing them to be expanded.

Next, a reversal command is outputted from the electric circuit 38 to the drive means of the pinch roll 6.6, whereby the pinch roll 6.6 is rotated in the opposite direction to the normal operating state (Fig. 11). (center arrow shown). For this reason, the intermediate guide 1
7 and the band-shaped intermediate product C in the lower guide 18 are pushed upward. On the other hand, the compacting rolls 7 and 7' continue to operate, and the remaining powder M from the outlet of the reduction furnace to the supply port 3 is continuously formed into a strip-shaped intermediate product C. Then, each guy 1 plate 19, 19' is expanded by the pressing force from this belt-shaped intermediate product C, and the molded belt-shaped intermediate product C is accommodated in the storage cage 21.

In addition, the reversal and command for the pinch roll 6.6 are as follows:
When the belt-shaped intermediate product C is discharged from these pinch rolls 6.6 and the load on these pinch rolls 6.6 is reduced, the release is automatically released. Also, compacting roll 7.7
By reducing the load at ', the self-holding in the electric circuit 38 described above is released, and preparations for normal operation are made.

Also, the limit switch 37 of the detection means 43 is turned ON.
In this case, the granulator A operates in the same manner as above.

Next, the band-shaped intermediate product C stored in the storage cage 21 as described above is shown by the imaginary line in FIG.

It is discharged from the granulator A by manual operation.

To explain this, first, the storage cage 21 is moved along the rail 20 (arrow S in the figure) and stopped at a predetermined position (shown by a chain double-dashed line in the figure). Next, the stopper 29
are removed, the lid members 27 and 27 are respectively rotated downward (mark E in the figure), and the band-shaped intermediate product C of the storage cage 21 is removed.
is discharged from the opening 21f (indicated by a chain line in the figure), thereby completing the processing of the belt-shaped intermediate product C at the time of misrolling.

In this case, the discharged belt-shaped intermediate product C is divided into briquettes B by using a separate means or the like.

Note that, as described above, since the storage cage 21 can be divided, the belt-shaped intermediate product C at the time of misrolling is attached to this storage cage 2.
If it becomes difficult to open and close each cover member 27 due to jamming inside the storage cage 1, the band-shaped intermediate product C can be discharged by dividing the storage cage 21.

Further, in the above embodiment, the operation of moving the accommodation cage 21 along the rail 20 and the operation of opening the lid member 27 are performed manually, but instead of this, each of the above operations is performed by each detection means 14. This may be done automatically via an actuator that is linked to the angle 43.

The following figures show other embodiments, and the different configurations from the above embodiments will be explained.

(Second example) FIG. 12 shows a second embodiment.

In the figure, the accommodation cage 21 is in an upper and lower position than in the first embodiment. A pair of detection means 47.47 having the same structure as the detection means 14.14 is also provided in the lower guide 18. Therefore, the detection of misroll is performed using the intermediate guide 1.
This is more reliable than being done with only the 7 position.

In addition, in the said structure, the accommodation cage 21 in 1st Example may be applied instead of the accommodation cage 21 of this structure.

(Third example) FIG. 13 shows a third embodiment.

In the figure, one guide plate 19, 19' is supported by a rail 20 via rollers 23 so as to be movable in the horizontal direction. These two guide plates 19.19' each detect means 14, 43.4.

Furthermore, a back-up plate 58 is provided between each of the belt pulleys 52, 53, and 54. The upper belt pulley 52. Intermediate belt pulley 54 and back-up plate 5
8 is supported by a rotating arm 59, and this rotating arm 59 is rotatable around the axis of the upper belt pulley 52. Also.

These pivot arms 59,59 are locked together by the locking means 24.

When guiding the belt-shaped intermediate product C between both belts 55 and 55, the intermediate belt pulley 54 and the back-up plate 58 are used to prevent each belt 55 from bending due to the pressing force from the belt-shaped intermediate product C. The pressure is stopped from being received from the back side of the belt 55.

Further, when the detecting means 14 , 43 , 47 detects a clogging phenomenon in the belt-shaped intermediate product C, the locked state by the locking means 24 is released. and both bells) 55.55
When a clogging phenomenon begins to occur between the belts, the rotating arm 59.59 expands due to the pressing force of this belt-shaped intermediate product C (arrow F in the figure).
, Accordingly, the bell) 55.55 is bent so as to expand (indicated by a chain double-dashed line in the figure). In this case, the tension arm 57 rotates due to the load from the belt 55 (
A predetermined tension force is applied to the belt 55 by a tension wheel 56 (arrow G in the figure). And the above bell) 5
The belt-shaped intermediate product C is accommodated between 5.55 and 55.

In the above case, if the detecting means 14, 43, 47 detects a clogging phenomenon in the belt-shaped intermediate product C, the belt 55
The drive of the tension wheel 56 may be stopped, and the biasing force of the tension wheel 56 against the belt 55 may be released. The belt 55 may also be a silent roller chain, a metal belt, a gamma belt made of rubber, or the like.

(Fifth Embodiment) FIGS. 15 and 16 show the locking means 24 in a fifth embodiment.

In the figure, a shaft 61 is screwed to the engaging concave member 26, and this shaft 61 is attached to a bracket 6 that is protruded from the frame member 21b.

(Effects of the Invention) According to the present invention, at least a part of the guide means is constituted by a pair of guide bodies facing each other with the band-shaped intermediate product in between,
A housing cage surrounding these guide bodies is provided, and both of the guide bodies are configured to be expandable within the housing cage, and a locking means for releasably locking the guide bodies to each other is provided. Since a pressing force detection means for detecting the pressing force from the belt-shaped intermediate product is provided in the middle part in the longitudinal direction, and the locking operation of the locking means is released by the detection signal of this detection means, mis-rolling occurs and the belt-like part against the detection means is When the pressing force of the intermediate product becomes larger than a predetermined value, both guide bodies can be expanded. Therefore, even if a misroll occurs and the weight of the belt-shaped intermediate product begins to increase between the guide bodies, the guide body expands accordingly, and the belt-shaped intermediate product is consolidated within the guide body, and the load from this belt-shaped intermediate product is increased. This prevents the granulator from becoming too large, thereby preventing damage to the granulator.

In addition, since the band-shaped intermediate product is not compacted within the guide body as described above, it is easy to discharge the band-shaped intermediate product from the guide body.

Moreover, in this case, since a storage cage surrounding both guide bodies is provided, the strip-shaped intermediate product accommodated during mis-rolling can be integrally carried out of the granulator system by this storage cage. Processing of the product is made easier.
