DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus capable of removing burrs generated at the end of a core during the molding of a cylindrical core such as an electronic component.

[0002]

2. Description of the Related Art As shown in the sectional views of FIGS. 7 to 10, a cylindrical core 21 has a pot shape shown in FIG. 7, a cylindrical shape shown in FIG.
There are various types such as the ring type in FIG. 9 and the drum type in FIG.
During molding, burrs 22 are formed near the ends and near the chamfers. It is necessary to remove these burrs 22. For this reason, the molded article is once transferred to a deburring step, and after removing the burrs, the molded article is transferred to a predetermined place.
The deburring operation in the deburring step was not easy to immediately adapt to various shapes of the cylindrical core 21, and was extremely inefficient.

[0003]

SUMMARY OF THE INVENTION The present invention incorporates a cylindrical core taken out of a molding process into a line for transporting the same, and burrs around the end of the cylindrical core and the entire periphery of the chamfered portion while transporting the core. An object of the present invention is to provide a deburring device which can be effectively removed in response to a change.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a traveling belt which is provided with an elastic barrier along a side edge of a conveyor and rotates the outer peripheral surface of a cylindrical core conveyed against the elastic barrier by preloading the outer peripheral surface. A deburring device is provided, wherein a deburring brush is disposed and is in contact with upper and lower outer peripheral portions of a cylindrical core conveyed along the elastic barrier.

[0005]

[Function] Conveyor 3 for taking out the molded cylindrical core 21
1 and the unloading conveyor 3
The cylindrical core 21 taken out by the conveyor 1
Between the elastic barrier 3 and the traveling belt 5, a preload is applied to the outer peripheral surface of the elastic barrier 3 by the traveling traveling belt 5, so that the rotating deburring brushes 8 ₁ and 8 ₂ rotate. To the burr removing brush 8
_1, passes between 8 _2, the entire periphery of the burr end and the chamfered portion is dropped. At this time, depending on the size of the cylindrical core 21,
Elastic barrier 3, running belt 5, deburring brush 8 ₁ , 8 ₂
And the preload of the running belt 5 are adjusted, and depending on the properties of the cylindrical core 21, for example, a wire brush or the like for a fired core, a brush of nylon or bristles for a raw core, a burr, or the like. The deburring brushes 8 ₁ , 8 ₂ are exchanged, and the deburring brushes 8 ₁ , 8 are adapted to cope with the shape of the cylindrical core 21, for example, the deburring of the inner end of the ring shape in FIG.
Make ₂ exchangeable or mobile.

Further, by providing the core guide 9 for guiding the conveyed cylindrical core 21 in a line between the elastic barrier 3 and the traveling belt 5 at the entrance side of the conveyer 1, the cylindrical core 21 can be surely secured. , The gap between the core guides 9 can be adjusted to correspond to the size of the cylindrical core 21, and the alignment guide 11 for aligning the cylindrical core 21 carried out to the outlet side of the conveyor 1 is provided. If provided, the cylindrical core 21 that has reached the outlet side of the conveyor 1 after being deburred is carried out to a predetermined position while being aligned by the alignment guide 11.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. 1 to 3. Reference numeral 1 denotes a work which is installed near the end of a take-out conveyor 31 in a molding step (not shown) and is taken out by the take-out conveyor 31. A transport conveyor on which the end face of the cylindrical core 21 is placed and transported. The transport conveyor is driven by a drive motor 2 and has an elastic barrier 3 made of an elastic material such as rubber along one side edge of the transport conveyor 1 for height adjustment. A possible pressure receiving member 4 is provided,
Inside of the belt, a traveling belt 5 of a round belt is
6. The belt 5 is installed so as to be able to run endlessly by a preload roller 7.7, and the outer peripheral surface of the conveyed cylindrical core 21 is preloaded against the elastic barrier 3 and rotated.
The height and the preload by the spring force can be adjusted. Further, deburring brushes _81, 82 are arranged vertically along the elastic barrier 3, these deburring brush 8 _1,
8 ₂ can be replaced on the outer circumferential upper and lower portions in a height adjustment and horizontal movable into sufficient contact, also in response to the properties of the cylindrical core 21 suitable deburring brush various cylindrical core 21 to be conveyed It has become.

Further, a core guide 9 for guiding the conveyed cylindrical core 21 in a line between the elastic barrier 3 and the traveling belt 5 is provided at the entrance side of the conveyer 1. The gap can be adjusted by moving the adjusting plate 10 by adjusting the bolt and the long hole in accordance with the size of the cylindrical core 21. The cylindrical core 21 after the deburring is completed is aligned with the exit side of the conveyor 1. An alignment guide 11 is provided for adjusting the gap, and is directly transferred to the sagger.

[0009]

As described above, according to the present invention, deburring is performed during transport of the cylindrical core, so that a separate step for deburring is not required, and handling is not required. It is possible to cope with it, productivity is improved, and it is also possible to deburr the chamfer at the same time as the end of the cylindrical core,
Adjustment functions such as a deburring brush, a preload running belt, and a core guide make it possible to support a wide range of products, and by replacing the deburring brush, it becomes possible to handle both fired cores and raw cores. Align the cylindrical core,
It has many beneficial effects, such as direct transfer to the sagger and reduction of equipment costs.
