A fixed throttle member 5 is fixed to the inner peripheral surface of the distal end of the compression cylinder 2, and a throttle outlet 6 is opened in the center of the fixed throttle member 5.
Further, a cylindrical die 7 having the same diameter as the compression die 2 is integrally connected to an opening front end thereof, and a discharge port 9 is opened at a front end of the cylindrical die 7. On the inner peripheral surface of the cylindrical die 7, ribs 8 for preventing rotation of a plurality of workpieces are fixed along the axial direction at intervals in the circumferential direction.

The transport cylinder 1 and the compression cylinder 2 of the casing C
A rotary shaft 11 having a single screw blade 12 integrally provided on the outer peripheral surface thereof extends vertically across the inside thereof, and the base end of the rotary shaft 11 has a slightly larger diameter than this. A drive shaft 14 rotatably supported by the casing C via a bearing 13 is integrally connected to the casing C. The drive shaft 14 is connected to a drive motor 15. Accordingly, the rotating shaft 10 is supported in a cantilever manner by the driving shaft 14 and is driven to rotate in the cylindrical portion of the casing 1 by the driving of the driving motor 15.

A homing head HF is fixed to the free end of the rotating shaft 11 and the screw blade 12
A straight cylindrical portion 11c composed of the outer peripheral surface of the rotating shaft 11 is formed between the end portion of the rotary shaft 11 and the homing head HF. An annular pre-compression chamber 16 is formed by the cylindrical portion 11c and the compression cylinder 2. Is formed.

As shown clearly in FIG. 2, the homing head HF has an outer 20o made of a spiral having a pitch of approximately 360 ° and having a pitch of about 360 ° on the outer peripheral surface of a cylindrical inner 20i fixed to the rotating shaft 11. It is configured to be fixed, its diameter is larger than the screw blade 12, and
Its width is thicker than the screw blade 12.
A cutout portion 21 is formed on one side in the radial direction of the outer body 20o of the head main body 20 so as to extend along the screw surface. The cutout portion 21 is open to the front and rear end surfaces of the head main body 20, Sharp front and rear edge portions 21Ef and 21Er are formed at the front and rear edges.

The lower part of the wall of the casing C corresponding to the pre-compression chamber 16, that is, the lower part of the compression cylinder 2, is provided with a device for regulating an object to be treated, which is a feature of the present invention.

Next, the structure of the apparatus for regulating an object to be treated will be described with reference to FIGS. 3 to 5. At the lower part of the compression cylinder 2, a rectangular opening 25 which is long in the axial direction is opened. A lid plate 24 for opening and closing the opening 25 is hingedly connected so as to be openable and closable, and a regulating member 27 that can enter or exit the pre-compression chamber 16 is erected on the inner surface of the lid 24 by welding or the like. It is fixed. The restricting member 27 is formed in a plate shape, and

Now, after rotating the rotating shaft 11 in the direction of arrow A in FIG. 1 by driving the drive motor 15, the light-weight waste such as paper waste and fiber waste, that is, the waste to be processed, which is selected from the municipal waste, is transferred to the hopper 4. When the processing object is put into the processing object, the processing object is conveyed forward while being compressed by the screw blade 12, and is gradually stored in the pre-compression chamber 16 and temporarily pre-compressed (primary compression). Is filled in the pre-compression chamber 16.

The pre-compressed workpiece is further transported forward and taken in by the rotating homing head HF, and cut by the notch 21 of the homing head HF.
Is further compressed (secondary compression) and transferred to the cylindrical die 7 in the cylindrical die 7.
The idle rotation is prevented by the ribs 8 and further transported forward, and is discharged to the outside through the discharge port 9. During this time, the object to be processed is solidified in a molten state during the primary and secondary compression. , And becomes a solidified molded product.

By the way, in the above-mentioned process of compressing and solidifying the object, if it is assumed that the object regulating device is not provided, the homing of the object pre-compressed in the pre-compression chamber 16 is performed. If the frictional force on the head HF is larger than the frictional force on the inner wall surface of the compression cylinder 2, the workpiece rotates together with the homing head HF, and cannot be taken into the homing head HF. An adverse effect occurs in that the processing efficiency of the object to be processed is reduced. In this embodiment, however, such an adverse effect can be eliminated by the presence of the object-to-be-processed control device. The precompression chamber 16
By restricting the control member 27 into the
After entering the workpiece, the workpiece and the homing head HF in the pre-compression chamber 16 are prevented from rotating together, and the workpiece is smoothly taken into the homing head HF. Can speed up the processing work. The arcuate surface 27o of the regulating member 27 helps to smoothly advance the workpiece to the homing head HF.

FIG. 6 is a sectional view of the apparatus for regulating an object to be treated. In FIG. 6, the same elements as those in the first embodiment are denoted by the same reference numerals.

In the second embodiment, a regulating member 27 welded to a cover plate 124 separated from a casing C is detachably attached to a plurality of bolts 33 on the wall surface of the casing C. Then, the regulating member 27
Is inserted into the pre-compression chamber 16 and the bolt 33 is removed, so that the regulating member 27 can be separated from the casing C together with the cover plate 124.

The second embodiment also has the first embodiment.
The same operation and effect as those of the embodiment can be obtained.

The first and second embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, and various embodiments are possible within the scope of the present invention.

For example, in the above-described embodiment, the object regulating device is provided at one place of the casing, but these may be provided at a plurality of places of the casing. Further, in the above embodiment, the regulating member is provided integrally with the cover plate, but they may be detachably attached.

[0028]

As described above, according to the first aspect of the present invention, in the volume reducing machine, the co-rotation of the homing head and the object to be processed is prevented, so that the homing head cuts the object to be processed. And the speed of the processing of the object can be greatly increased.
