DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip processing device for collecting and processing metal chips generated by a machine tool such as a lathe.

[0002]

2. Description of the Related Art Generally, chips are generated when a metal material is processed by a processing machine such as a lathe and a drilling machine. In particular, when an aluminum material is processed, continuous chips are generated in a thread shape. Since the chips have elasticity, the volume is large in proportion to the weight, and a great deal of labor is required for processing the chips. Therefore, various chip processing apparatuses have been proposed.

[0005] A chip processing apparatus 50 shown in FIG. 5 includes a processing tank 51 and a dust collector 55, and chips generated by a processing machine such as a lathe and a drilling machine (not shown) pass through a transport duct 52. It is sucked into the processing tank 51. The processing tank 51 is provided with a bucket 53 for temporarily storing chips, the air that has sucked the chips is separated from the chips by a filter 54, introduced into a blower motor 56 of a dust collector 55, and provided with an exhaust port with a silencer 57. It is discharged to the outside from 58. This chip processing device 50 carries out the bucket 53 from a door (not shown) of the processing tank 51 to a chip processing site when the bucket 53 is full of chips.

[0006] A chip processing apparatus 60 shown in FIG. 6 is provided with a chip crusher 62 in a dust collector 61. The swarf processing device 60 sucks swarf generated by a cutting machine such as a lathe (not shown) into a crusher 62 via a transport duct 63, and cuts a continuous thread-shaped swarf with the crusher 62. It is sent into the bucket 64 and temporarily stored. The air for sucking the chips is introduced into a blower motor 65 and discharged to the outside through an exhaust port 66. Since the chip processing device 60 cuts the thread-shaped continuous chips in a short length, the bucket 64 can be reduced in size and the whole device can be made compact. , Which are carried out from a door (not shown) to a chip processing site.

[0005]

However, the above-mentioned conventional chip processing apparatus has the following problems. First, in the chip processing device 50, since the thread-shaped continuous chips are long and elastic, the volume occupied by the chips becomes very large in proportion to the weight thereof, and the bucket 53 immediately becomes full. In addition, there is a problem that the operator has to frequently take out the chips and process the chips, and the processing operation is troublesome. Also, in the chip processing device 60, even if a long continuous thread-shaped chip is cut and shortened, the volume is reduced to some extent, and the bucket 6
Since the chip 4 is downsized, the chips are immediately filled up, and the operator must frequently take out and process the chips, which is a problem in that the processing work is troublesome. Further, the chip processing device 60 has a problem that the cost of the device is increased because the crusher 62 is provided.

The present invention has been made in view of such a situation, and the processing is simplified by compressing the chips generated by the cutting process, thereby simplifying the processing. An object of the present invention is to provide an inexpensive chip processing apparatus which is unnecessary and inexpensive.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view showing the configuration of the entire chip processing apparatus according to the present invention, FIG. 2 is a partially cutaway front view showing a pre-tank of the chip processing apparatus shown in FIG. 1, and FIG. 3 is a chip shown in FIG. FIG. 4 is a partially cutaway side view showing a pre-tank of the processing apparatus, and FIG. 4 is an explanatory view showing a state of chip processing by the chip processing apparatus of FIG.

As shown in FIG. 1, the chip processing apparatus according to the present invention includes a pre-tank A for temporarily storing and processing chips and a dust collecting apparatus B for sucking chips. The pre-tank A and the dust collector B are connected by a duct C. As shown in FIGS. 2 and 3, the pre-tank A has a main body 1 having an upper portion formed in a cylindrical shape and a lower portion formed in a hopper shape, and a suction port 2 is provided in an upper portion of the main body 1. And a transport duct 3 for sucking chips generated by a processing machine such as a lathe (not shown). A connection port 4 is provided at a substantially central portion of the upper surface of the main body 1, and a duct C communicating with the dust collecting device B is connected to the connection port 4. Further, a filter 5 is mounted in the main body 1 of the connection port 4 to prevent chips from flowing into the dust collector B.

At the lower part of the main body 1, a side plate of the main body 1 is partially hung down to form a mounting plate 1a.
A caster 6 is attached to the lower end of the caster. The main body 1 is movable together with casters 7 and 8 attached to a screw type chip conveyor 10 described later. Further, a screw type chip conveyor 10 which is a means for transporting chips is attached to the input port 9 at the lower end of the main body 1 formed in a hopper shape. The screw tip conveyor 10 includes a screw shaft 12 which thus times <br/> rotation to the drive motor 11 forward, and discharge tube 13 which is inclined <br/> obliquely upward is provided in the rear, this Discharge cylinder part 1
A lid 14 having a predetermined weight is attached to the outlet 13a of the third.

The function of the lid 14 is that if there is no lid 14 and there is no swarf in the discharge cylinder 3, the dust collecting device B
This prevents the air from being sucked into the main body 1 from the outlet 13a, thereby lowering the suction ability from the suction port 2, and is compressed by the screw shaft 12 as shown in FIG. cuttings discharge tube 13
It does not open until it is full. Chips extruded by the screw shaft 12 in this state are:
Since the chips are compressed to a predetermined pressure, the volume of the chips is gradually reduced, and elasticity is lost. The discharge tube is compressed by the screw shaft 12
The swarf sequentially pushed out to the part 13 pushes the lid 14 open as shown in FIG. At this time, discharge
Since the cylindrical portion 13 is full of chips, air is not sucked from the outlet 13a. From this state, the chips are discharged from the outlet 13
It is extruded from outside a and falls and is accommodated in the bucket 15.

As shown in FIG. 1, in the chip processing apparatus thus configured, chips are sucked into the pre-tank A together with air through a duct C by a blower motor (not shown) of a dust collector B. Then, the chips fall downward in the main body 1, and the sucked air passes through the filter 5, is sucked from the duct C by the dust collecting device B, and is discharged to the air. The chips that have fallen in the main body 1 are introduced into the screw type chip conveyor 10 through the introduction port 9. Then, the swarf fed into the screw type chip conveyor 10 is
Since the chips 2 are forcibly conveyed by rotation, the chips may collide with each other or may be compressed by the screw shaft 12 and may be partially cut. As a result, the volume of the discharge cylinder 13 is further reduced.

In this way, the chips fed into the screw type chip conveyor 10 are cut while being compressed by the screw shaft 12 during transportation. Since it is compressed to 1/20 or less of the volume of the swarf, the storability is extremely excellent, and the work of taking out the bucket 15 frequently becomes unnecessary. In addition, the screw type chip conveyor 10
The pre-tank A to which is attached has a simple structure and can reduce the cost of the chip processing device. In addition,
It is a matter of course that the transporting means may be of another type as long as the chips are compressed and transported.

[0014]

As described above, in the chip processing apparatus of the present invention ,
Has chips sucked from the suction port of the main body of Puretanku is Ri by the screw tip conveyor is conveying means
When it is discharged to the outside of the body, the discharge tube portion which is inclined upward
Press and open the lid while being compressed by the lid of the specified weight to discharge
Is done. Therefore, according to the chip processing apparatus of the present invention,
For example, the volume of the chips discharged from the main body of the tank to the bucket is greatly reduced, and the frequent removal of the bucket is not required.
