Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an individual piece cutting apparatus that cuts a hoop-shaped material into individual pieces and conveys and supplies the cut individual pieces to a predetermined location.
[0002]
[Prior art]
Conventionally, as a configuration in which a hoop-shaped material is cut into pieces having a predetermined shape and the cut piece material is conveyed and supplied to a predetermined portion, a slider or the like that can be reciprocated by sliding on a lower mold in a mold is used. It is configured to be mounted and transported to a predetermined location while positioning and holding the cut piece material on the slider or the like.
[0003]
[Problems to be solved by the invention]
However, in the conventional configuration, since the cut piece material cut from the hoop-shaped material is conveyed and supplied to a predetermined location, it is conveyed and supplied by a linear reciprocating motion such as a slider. Due to the time required for the linear reciprocating movement of the slider or the like, it has been difficult to make the tact of the piece cutting device faster than a certain level.
[0004]
The present invention is intended to solve the above-mentioned problems, and the time required to convey and supply the cut piece material to a predetermined location can be shortened compared to a linear reciprocating operation such as a slider, and high-speed tact can be achieved. The object is to provide a possible piece cutting device.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, an individual piece cutting apparatus according to the present invention includes a cutting die and a cutting die that cut a hoop material into a cut individual piece material , a lower die, and a position immediately below the cutting die. a rotatably disposed, circular buried a plurality of holding and transporting pin for mounting the cutting pieces material around at predetermined intervals or in singulation device and a carrier of polygonal shape, The holding and conveying pins are provided with air holes for vacuum suction, the cutting punch is provided with air holes for exhausting air, and the holding and conveying pins are vacuum-sucked and air is exhausted from the cutting punch. After the piece material is detached and sucked and held by the holding and conveying pins, the carrier is rotated to convey the cut piece material to the next process .
[0006]
Since the individual piece cutting device having the above-described configuration is used to convey and supply the cut piece material by the rotational movement operation, the time required to convey and supply the cut piece material is compared with a linear reciprocating movement operation such as a slider. Can be shortened and the tact time can be increased.
[0007]
The invention according to claim 1 of the present invention has a cutting punch and a cutting die for cutting a hoop material into a cut piece material, and is rotatable freely below the lower die and the cutting die. provided, circle buried a plurality of holding and transporting pin for mounting the cutting pieces material around at a predetermined interval or a singulation apparatus having a carrier of polygonal shape, said The holding and conveying pins are provided with air holes for vacuum suction, and the cutting punch is provided with air holes for exhausting air. The holding and conveying pins are vacuum-sucked and air is exhausted from the cutting punches, so that the cut pieces are separated. After the suction and holding to the holding and conveying pins, the carrier is rotated to convey the cut piece material to the next process , and the cut piece material is attached to the tip of the cutting punch. To prevent sticking In, it has an effect of capable of carrying supplies cut pieces materials, fast and reliably held by the holding transport pins.

[0013]
Reference numeral 6 denotes an upper backing plate that is in close contact with the upper surface of the punch plate 5, and 7 is a punch holder that can be moved up and down so that the upper backing plate 6 is in close contact with the lower surface. An air hole 26 connected to the air hole 23 is provided.
[0014]
14 is a material presser plate in which a hole 21 through which the cutting punch 2 is inserted and a processing hole 22 through which the processing portion 15 slides and is connected are provided, and an insertion hole for the post 4 is provided at one end.
[0015]
9 is a suspension bolt whose lower end is fixed to the upper end portion of the material presser plate 14, and its main body portion is inserted vertically through insertion holes provided in the punch plate 5 and the upper backing plate 6, and its upper end portion is It moves through a hole provided in the punch holder 7 and is regulated by the lower surface of the punch holder 7, that is, the upper surface of the upper backing plate 6, and holds the material pressing plate 14 at a predetermined position in the vertical direction.
[0016]
A compression spring 10 is disposed in a hole provided in the punch holder 7. The upper end is held by the punch holder 7 by a set screw 11, the lower end abuts on the upper surface of the suspension bolt 9, and the suspension bolt 9 is lowered. It is energizing in the direction. As described above, the upper mold is formed by the configuration excluding the die plate 12 and the die holder 8.
[0017]
As described above, 12 is a die plate in which a cutting die 3 made of super steel material is embedded and fixed. Similarly, 8 is a die holder which is in close contact with the lower surface of the die plate 12 and has a hole 27 connected to the processed portion 16.
[0018]
Reference numeral 17 denotes a base, the upper end of which is closely fixed to the four corners of the lower surface of the die holder 8 to hold the die holder 8. Reference numeral 18 denotes a shaft which is rotatably installed on the base 17 and is fixed to the center of a circular or polygonal carrier 19 at the upper end.
