[0016]

An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a schematic configuration of a refuse supply apparatus having a refuse bag breaking function according to the present invention.

In FIG. 1, reference numeral 1 denotes a housing of a refuse supply device, in which an input port 11 is formed at the top of the housing 1, a refuse supply port 12 is provided at one end of a bottom, and a foreign substance discharge port 13 is provided at the other end. Is formed.

Screws 3 are arranged in the housing 1 in parallel with each other, and both ends of the screw 3 are rotatably supported on the side wall of the housing 1 via bearings 3a.

Further, a first partition plate 4 is disposed in the housing 1 in a direction substantially perpendicular to the direction in which the screws 3 are disposed. The first partition plate 4 is disposed closer to the dust supply port 12 than the input port 11.
The interior of the housing 1 is divided into a receiving portion 15 for receiving the dust input from the input port 11 and a supply portion 16 on the dust supply port 12 side.

The first partition plate 4 has a through hole 41 through which the screw 3 is disposed. The diameter of the through hole 41 is slightly larger than the diameter of the screw blade 31 of the screw 3.

A second partition plate 2 for separating the left and right screws 3, 3 is provided in the supply section 16.

The screw 3 is, as shown in FIG.
The screw blade 31 is formed in a spiral shape on the peripheral surface of the shaft portion 32. The screw 3 has a portion arranged in the receiving portion 15 formed continuously and integrally, and a portion arranged in the supply portion 16 is formed intermittently by a plurality of blades 31a.

Here, the plurality of blades 31a are arranged such that the adjacent blades 31a overlap each other in the axial direction of the screw 3 as compared with the trajectory of the continuously formed screw blades (see the two-dot chain line). In the illustrated example, the end A of the blade 31a and the start B of the adjacent blade 31a are arranged.
Are substantially matched in the axial direction of the screw 3.

By forming the plurality of blades 31a in this manner, a gap is formed between the adjacent blades 31a, and the gap causes the dust bag to be broken when the screw described later is driven. The ability to bag is obtained. Note that the plurality of blades 31a also have the original transfer capability of the screw 3.

A plurality of fixed blades 51 and 52 are provided on the inner wall of the housing 1 forming the supply section 16.
The fixed blade 51 is fixedly arranged on the bottom of the housing 1 formed by the supply unit 16, and the fixed blade 52 is fixedly arranged on the side wall of the housing 1 formed by the supply unit 16 and the second partition plate 2. These fixed blades 51 and 52 are for breaking a garbage bag between the plurality of blade bodies 31a, and also serve to roughly crush large garbage.

The two screws 3 configured as described above are separately and independently driven by drive motors 6 provided on respective sides of the housing 1. Drive motor 6
The output shaft 61 is connected to one end of the shaft of the screw 3. By driving the drive motor 6, the screw 3 can be driven to rotate in the forward and reverse directions.

The drive motor 6 is driven by an overload current when the drive of the drive motor 6 is loaded with a predetermined load or more, that is, when the drive of the screw 3 is loaded with a predetermined load or more. 3 is configured to rotate in the reverse direction. The drive motor 6 normally rotates the screw 3 so as to convey dust from the receiving unit 15 to the supply unit 16.

Further, as shown in FIG. 3, the housing 1 is vertically divided into an upper housing 1a and a lower housing 1b from a portion located substantially at the center of the screw 3 to be provided, and a bolt or the like is provided. Is released by releasing the appropriate securing means. By separating the housing vertically, maintenance and repair can be easily performed.

Next, the operation of the refuse supply device provided with the refuse bag function according to the present invention will be described.

First, waste is put into the housing 1 through the input port 11.
Into the receiving unit 15. At this time, the screw 3 is rotationally driven so as to convey the dust from the receiving unit 15 to the supply unit 16, and the dust input into the receiving unit 15 is rotated by the screw 3 and is conveyed by the screw blade 31. It is transported to the supply unit 16.

In the supply section 16, the plurality of blades 31a formed on the screw 3 transport the garbage bag containing the garbage to the garbage supply port 12 while breaking the bag, and carry out the garbage from the garbage supply port 12. Specifically, in the supply unit 16, the garbage bag is transported by being rotated by the screw 3 while entering the gap formed between the plurality of blade bodies 31a, so that the garbage bag is transported while being caught in the gap between the blade bodies 31a, Further, in combination with the action of the fixed blades 51 and 52, the bag is further broken and carried out from the refuse supply port 12.

Then, the conveyed refuse is conveyed to an appropriate subsequent device such as a sorting device or a drying device.

Further, the fixed blades 51 and 52 have the function of breaking the garbage bag described above, and can also roughly crush the large-sized garbage between the garbage bag and the screw 3.

Since the plurality of blades 31a are arranged such that the adjacent blades 31a are overlapped in the axial direction of the screw with respect to the trajectory of the continuously formed screw blade, the transfer capability is increased. Can be prevented from remarkably lowering, and refuse can be transported smoothly.

As described above, the refuse introduced into the receiving section 15 is conveyed from the receiving section 15 to the supply section 16 by the screw 3, and a through hole 41 is provided from the receiving section 15 to the supply section 16. It has been inserted and transported. At this time, large dust that does not pass between the through-hole 41 and the screw 3 is clogged by the through-hole 41 and hinders rotation of the screw 3. In such a case, the drive motor 6 generates an overload current, so that the screw 3 is rotated in the reverse direction by the overload current, and the dust clogged in the through-hole 41 is regarded as foreign matter, and the foreign matter discharge port 13
Discharged from

More specifically, for example, when dust is clogged in the through hole 41 and an overload current is generated, the operation of rotating the screw 3 slightly in the reverse direction and then rotating it forward again is repeated about three times. If the clogging cannot be released at 41, the screw 3 is rotated in the reverse direction for a time sufficient to be regarded as foreign matter and discharged from the foreign matter discharge port 13.

As described above, by controlling the rotation of the screw 3 in the forward / reverse direction, it is possible to provide a refuse supply device having a foreign matter sorting function.

Further, since the two screws 3 are separately and independently driven by different driving devices, the driving of the other screw 3 can be continued even if one of the screws 3 has a problem or failure. It can be operated efficiently.
