Field of the Invention The present invention relates to a chip processing machine for removing chips generated by cutting, cutting and the like. 2. Description of the Related Art The inside of a punching blade is used for cutting or cutting the wall surface of a bottomed tubular molded body made of a thermoplastic resin such as a blood collection tube, or for making a hole with a high frequency or ultrasonic welder. Chips are sucked and removed under a negative pressure, but it is troublesome work to remove the chips because they adhere to the wall surface and are difficult to separate. For this reason, a chip processing machine as shown in FIG. 1 has been conventionally used. [0003] In the chip processing machine 4, first, while pressing the bottomed tubular formed body 1 having the chip 3 adhered to the wall surface with the push rod 2, the molded body 1 is inserted into the insertion hole 7 from the opening thereof, and the chip 3 is cut. Insertion is continued until reaches the suction hole 6. Next, after operating the vacuum pump (not shown) to suck and remove the chips 3 from the suction holes 6, the molded body 1 is inserted into the insertion holes 7 together with the push rod 2.
, And the molded body 1 is taken out. However, in the processing machine 4, there is no problem when the bottomed tubular molded body 1 is inserted into the insertion hole 7, but when the molded body 1 is pulled out from the insertion hole 7 after removing chips.
Since there is only a small gap between the insertion hole 6 and the tubular molded body 1,
There was a case where only the push rod 2 came off and the molded body 1 was left inside the processing machine 4. For this reason, the chip processing machine 4 has a structure capable of being separated from the joining surface 5 into two parts. If the molded body 1 cannot be taken out from the insertion hole 7 properly, the processing machine 4 is connected to the joining surface 5. However, since it is necessary to separate the sheet from the tray 5, the extraction operation is troublesome and time-consuming. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to completely remove chips with a simple operation, and to provide an apparatus which can An object of the present invention is to provide a chip processing machine capable of easily removing a bottomed tubular molded body without disassembly. According to the present invention, there is provided a chip processing machine comprising: an insertion hole for inserting a tubular molded body; a suction hole for sucking chips attached to an outer surface of the molded body; And a discharge tool. [0008] A chip processing machine of the present invention will be described with reference to the drawings. FIG. 2 is a schematic diagram showing an outline of the chip processing machine 14. The chip processing machine 14 has an insertion hole 17 into which the bottomed tubular molded body 11 for removing chips is inserted.
, And a suction hole 16 intersecting with the insertion hole 17. Further, both openings of the suction hole 16 are connected to a vacuum pump (not shown), and have a structure that can be sucked from both openings by operation of the vacuum pump. A method for removing the chips 13 attached to the outer surface of the bottomed tubular molded body 11 using the chip processing machine 14 will be described. First, in order to insert the tubular molded body 11 from the opening below the insertion hole 17, the push rod 12
Is used. The push rod 12 is inserted into the inside of the molded body 11, and the molded body 11 is moved upward by pressing it, and is pushed up until the chips 13 attached to the outer surface of the tubular molded body 11 reach the suction holes 16. When the chips 13 reach the suction holes 16, the pressing by the push rod 12 is stopped and stopped at that position, and then the vacuum pump is operated to suck the chips from both openings of the suction holes 16. By this suction, the chips 13 are sucked and removed from both openings of the suction hole 16. This suction is continued until the chips 13 are completely removed. Next, when the chips 13 are completely sucked and removed from the suction hole 16, the discharge rod 18 is inserted from the opening above the insertion hole 17 with the push rod 12 inserted into the molded body 11. Then, the molded body 11 is pushed down and discharged from the opening below the insertion hole 17. In the chip processing machine of the present invention, since the inside of the suction hole 16 is kept under reduced pressure, the hole diameter of the insertion hole 17 is very small when the molded body 11 is inserted. Since the push rod 12 is simply lowered, the push rod 12 comes out of the molded body 11.
The molded body 11 may be left in the insertion hole 17,
In order to reliably remove the molded body 11 from the insertion hole 17, the molded body 11 is pressed by the discharge rod 18. After the molded body 11 is discharged from the insertion hole 17, another molded body is pressed from the opening below the insertion hole 17 with a push rod and inserted. Is aspirated and removed. The operation method of the push rod 12 and the discharge rod 18 is not particularly limited.
It can be operated by a hydraulic cylinder or the like. In FIG. 2, the insertion hole 17 is provided in the up and down direction, and the suction hole 16 is provided in the left and right direction. However, the present invention is not limited to this. As shown in FIG. Alternatively, suction holes 16 may be provided in the vertical direction. Although only one suction hole 16 is provided in FIGS. 2 and 3, a plurality of suction holes 16 may be formed so as to intersect with each other at the insertion hole 17. An embodiment of the present invention will be described below. (Example 1) 100 parts by weight of vinyl chloride resin and plasticizer 5
When a hole having a diameter of 2 mm was formed on the side surface of a bottomed tubular molded article (outer diameter 6 mm, inner diameter 4 mm) formed from a resin composition consisting of 0 parts by weight using an ultrasonic welder, chips were not completely removed. However, some of the swarf remained adhered in a state protruding from the side surface. Next, a push rod was inserted into the inside of the formed body having the hole, and the formed body was inserted into the insertion hole (diameter 7) of the chip processing machine shown in FIG.
mm), the push rod was moved upward, and the push rod was pushed up until the chips reached the suction holes. When the chips reached the suction holes, the vacuum pump was operated to suction through both openings of the suction holes to remove the chips. Next, after the vacuum pump was stopped, a discharge rod was inserted from the other opening of the insertion hole, and the tube was easily discharged by pushing down the bottomed tube. In addition, the chips were completely removed from the discharged molded body. The structure of the chip processing machine of the present invention is as described above, and it is possible to completely remove the chips of the bottomed tubular molded body and to discharge the molded body with a discharge rod. By extruding, it can be easily taken out of the chip processing machine.
