塊状物５０が残留することはほとんどない。In general, a kneaded product or the like has low fluidity, but has a property that it tends to be lumped due to its own weight in the hopper. On the other hand, the blades 21 of the screw 20 are discontinuous, the pitch of the blades 21 is wider near the rear end 20b than near the tip 20a, and the size of the blade 21 is larger than near the tip 20a. Since the vicinity of the portion 20b is made larger and the pitch of the blades 21 is made smaller than the forward / backward stroke of the screw 20, the blades are better caught in the lump, and the forward / backward movement of the screw 20 allows the screw 20 to move forward and backward. The lumps scraped out by the blades 21 near the front end portion 20a are sequentially sent to the blades 21 near the rear end portion 20b. Therefore, even the lumps in the inner part of the hopper can be pulled toward the opening portion side and scraped out. At this time, the lumps scraped out by the blades 21 in the vicinity of the tip end portion 20a are located behind the lumps. It becomes integrated with the lumps scraped out by the blades 21, and the amount thereof gradually increases.
As a result, the scraping efficiency is improved as compared with the case where the blades of the screw 20 are continuous, and the supply of the kneaded product to the granulating device or the like is stabilized. Moreover, since the mass of the kneaded product scraped out is not so large, the flowability of the kneaded product in the granulating device or the like is good. In addition, the bottom surface 13 of the hopper 10 is provided with an opening 12
Since the neighborhood is inclined so as to be the lowest, the lump 50 tends to slide on the inclined bottom surface 13 by the action of gravity. Therefore, the scraping load by the screw 20 becomes small, and the torque required to drive the screw 20 becomes small. In addition, since the bottom surface 13 of the hopper 10 is formed into a substantially fan shape and the opening 12 side is narrowed, the swinging operation of the screw 20 can cover almost the entire bottom surface 13 of the hopper 10 without waste, and the entire portion. The lumps of can be scraped out. As a result, the lumps 50 hardly remain in the hopper 10.

塊状物供給装置に供給することができる。As described above, according to the present invention, the lumps such as the kneaded material temporarily stored in the hopper are gradually rotated from the front end to the rear end of the screw by the rotation of the screw. Since they are scraped out one by one and discharged from the opening to the outside of the hopper, it is possible to continuously scrape out a lump such as a kneaded product and automatically supply it to a cylindrical extrusion granulator or the like. At this time, by moving the screw back and forth in a direction substantially orthogonal to the opening, the lumps at the corners of the bottom of the hopper can be scraped out and the discharge of the lumps can be promoted. In addition to this operation, the screw can be swung parallel to the bottom surface of the hopper by a predetermined angle to scrape out the lump of the next portion. Since the lump in the hopper is dug in a tunnel shape and a fan shape by a screw, the dug portion is sequentially lowered by its own weight. Therefore, by swiveling the screw in a predetermined direction as much as possible, and then repeating the same operation while swinging in the opposite direction, almost all the lumps temporarily stored in the hopper are not left. It can be continuously scraped out and supplied to an agglomerate supply device such as a cylindrical extrusion granulator.

Also, by making the pitch of the blades of the screw smaller than the stroke of forward and backward movement of the screw, the forward and backward movement of the screw causes the lumps scraped by the blades at the front end of the screw to be sent to the blades at the rear end in order. You can
Therefore, even a lump in the inner part of the hopper can be pulled toward the opening and scraped out. Further, at this time, the lumps scraped out by the blades at the leading end are integrated with the lumps scraped by the blades at the rear end, and the amount thereof gradually increases. As a result, the scraping efficiency can be improved as compared with the case where the blades of the screw are continuous. Further, by making the pitch of the blade of the screw wider in the vicinity of the rear end than in the vicinity of the front end, and making the size of the blade larger in the vicinity of the rear end than in the vicinity of the front end,
The scraping efficiency can be further improved.

を防止することができる。Further, by inclining the bottom surface of the hopper so that the vicinity of the opening is the lowest, the lump tends to slide on the inclined bottom surface due to the action of gravity, so that the scraping load by the screw can be reduced. . As a result, the torque required to drive the screw is reduced, and the motor of the screw drive device can be reduced in size. In addition, the bottom of the hopper is made into a fan shape,
By narrowing the opening side, it is possible to scrape out the lumps of almost the entire portion without wasting the bottom surface of the hopper by the swinging operation of the screw. As a result, few lumps remain in the hopper. Further, among the respective operations of the screw by the screw drive device, by driving at least forward and backward and swinging with compressed air,
Even if the load of the screw fluctuates due to the lumps attached to the screw, the fluctuation of the load can be easily absorbed, and the seizure of the motor as in the case of using an electric motor can be prevented.

状物を常に一定のレベルに保つことができる。Further, the lump can be continuously supplied by arranging the hopper of the lump supply device such as a cylindrical extrusion granulating device for receiving the lump supply below the opening of the hopper. In addition, a level detector is provided in the hopper of the lump feed device, and the screw rotates, moves forward and backward, and swings according to the remaining amount of lump in the hopper of the lump feed device detected by the level detector. By controlling the above, it is possible to prevent excessive supply or insufficient supply of the lumps to the lump supply device, and it is possible to always keep the lumps in the hopper of the lump supply device at a constant level.
