Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chip distribution device for collecting chips emitted from a machine tool into a chip box.

[0002]

[Prior art]

 As is well known, a large amount of cutting chips are produced from the machine tool during the product making process, but in order to remove these chips from the machine room, they are continuously discharged from the machine room using an automatic conveyor, and these chips are continuously discharged. The method of putting into a chip box that can be run is generally adopted.

In such a conventional chip collecting method, the chips falling from the conveyor accumulate in a conical shape in the chip box. The piles of chips that have risen are broken down by hand, and the chips are evenly distributed in the chip box to improve the storage efficiency in the chip box.

[0004]

[Problems to be solved by the device]

 However, since such a conventional method of collecting chips is carried out as described above, the work of breaking the pile of chips rising in the above-mentioned conical shape is performed manually, which is a heavy burden on the operator. In addition, the efficiency of chip discharge is poor, and the efficiency of storing chips in the chip box is extremely poor. For example, when mixing curled chips, 1/5 to 1/1 / of the box volume There was a problem such as about 6.

The present invention has been made by paying attention to the above-mentioned conventional problems, and by distributing the cutting chips into the chip box and automatically charging them, the burden on the operator is eliminated and the cutting chips It is an object of the present invention to provide a chip distribution device capable of enhancing both storage efficiency and delivery efficiency.

[0006]

[Means for Solving the Problems]

 A chip distribution device according to the present invention is provided at a lower end of a hopper which is arranged above a chip box and receives chips fed from above, and a chip distribution pipe curved outward from a center line of the hopper. The hopper is supported so as to be horizontally rotatable, and a drive source is connected to the hopper via a transmission mechanism so as to be rotatable. Further, the chip distribution device according to the present invention is provided at the lower end of a hopper which is arranged above the chip box and receives chips introduced from above, and which is curved outward from the center line of the hopper. A distribution pipe is rotatably connected in series, and a driving source is connected to the chip distribution pipe through a transmission mechanism to enable rotation. Further, the chip distribution pipe is characterized in that a chip crushing member for crushing the chips in the chip box is continuously provided.

[0007]

[Action]

 The hopper is supported so as to be horizontally rotatable, and is rotated because it is connected to a drive source via a transmission mechanism. Therefore, the chip distribution pipe connected to this hopper also rotates together with the hopper (Claim 1). Further, since the chip distribution pipe is rotatably connected to the hopper and is connected to the drive source through the transmission mechanism, the chip distribution pipe is rotated (claim 2). By the rotation of the chip distribution pipe, the chips introduced into the hopper are introduced almost uniformly toward the entire periphery of the inside of the chip box. Therefore, the chips are evenly distributed over the entire area of the chip box, and the efficiency of storing the chips is improved.

Further, when the chip distribution tube is rotating, the chip distribution tube that rotates even if the cutting chips thrown into the chip box partially rise up collapses. Uniformity is achieved over the entire area of the box, increasing storage efficiency. The efficiency of this chip crushing is further enhanced if a chip crushing member is connected to the chip distribution pipe (claim 3).

[0009]

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the whole of the chip distribution device of the present invention. In FIG. 1, reference numeral 1 is a conveyor device for automatically conveying the chips discharged from a machine tool from a work site. It consists of conveyors such as belts, buckets, chains, etc. It functions to transport chips from the bottom to the top and drop them from the top to the hopper.

Reference numeral 2 denotes the hopper that is open toward the upper end of the conveyor device 1. At the lower end of the hopper 2, a curved portion that is partially curved outward from the center line of the hopper 2. A chip distribution pipe 3 having 3a is integrally connected. Reference numeral 4 is an upper end portion of the chip distribution pipe 3, which is a ring-shaped roller chain attached to a non-curved portion, and 5 is a rotary table which supports the roller chain 4.

Further, 6 is a gear that meshes with the roller chain 4 and horizontally rotates it. The gear 6 is rotatably supported on a mounting base 7 mounted on the conveyor device 1. Reference numeral 8 denotes a hopper turning motor that drives the gear 6 to be horizontally rotatable.

Further, 9 is a bearing mount provided so as to surround a part of the chip distribution pipe 3, which is fixed to one end of the mount 7 by a bolt 11 or the like. Reference numeral 10 designates bearings provided at a plurality of positions on the bearing mount 9, and these bearings support a rotary base 5 integrated with the roller chain 4 so as to be horizontally rotatable.

Reference numeral 12 denotes a chip crushing member protrudingly provided at the lower end portion of the chip distributing pipe 3, which has a rod shape and extends horizontally in the upper part of the chip box 13 as necessary. The horizontal portion 12a may be located inside the chip box 13. The chip breaking member 12 is not always necessary, but if it is present, the effect is further improved.

In the chip distribution device having such a configuration, first, the chips collected from the periphery of the machine tool are placed on the conveyor of the conveyor device and conveyed upward. Then, the chips fall from the conveyor, are thrown into the hopper 2 facing the lower part of the conveyor, and fall inside the chip distribution pipe 3 so as to slide obliquely downward at the curved portion.

On the other hand, at this time, since the roller chain 4 is horizontally rotated by the gear 6 by the driving of the motor 8, the hopper 2 and the chip distribution pipe 3 are supported by the bearing 10 and similarly smoothly horizontally rotate, The chips are discharged (input) from the lower end of the chip distribution pipe 3 to the periphery inside the chip box 13.

Therefore, the chips are distributed and stored in the entire chip box 13 substantially uniformly. Further, even if the chips are swelled in the swarf box 13, the swarf distribution pipe 3 and the swarf breaker member 12 forcibly collapse the tops of these swelled mountains by rotation, and The powder is distributed and stored almost uniformly in the entire chip box 13.

In the above embodiment, the chip distribution tube 3 is fixed to the hopper 2 and the chip distribution tube 3 is rotated by rotating the hopper 2. However, the present invention is not limited to this. The chip distribution pipe 3 may be rotatably connected to the lid 2, and a motor may be connected to the chip distribution pipe 3 via a transmission mechanism so as to rotate.

[0018]

【The invention's effect】

 As described above, according to the present invention, since the chip distribution pipe is rotated so that the chips are distributed in the entire chip box in a substantially uniform manner, the chips are formed in one place. The advantage is that chips can be efficiently stored in the chip box, and that this can be easily realized with a simple and inexpensive structure.
