[0010]
As shown in FIG. 2, a concave notch (a) is formed on the rising side of each of the left and right moving bodies 16a and 16b and on the opposite side (lower part and upper part) of the vertically moving bodies 18a and 18b. (A) is a size that allows the rotary cutters 12a and 12b described above to pass left and right. Conveying main body portions 20a, 20b comprising guide rails 21a, 21b extending in the front-rear direction at opposite ends (lower end portion and upper end portion) of the vertical moving bodies 18a, 18b and endless toothed conveying belts 22a, 22b. Install.
[0011]
The upper transfer main body 20a and the lower transfer main body 20b have the same structure facing each other vertically, and the upper transfer main body 20a will be described below with reference to FIG. An elongated rectangular guide rail 21a is extended in the front-rear direction and fixed to the lower end of the upper moving body 18a, and toothed pulleys 23a, 23a are attached to the front and rear ends of the guide rail 21a, and the toothed pulleys 23a, 23a The presser pulleys 24a and 24a are rotatably attached to the upper side.
[0012]
A bracket 25a is erected and fixed to an intermediate portion in the front-rear (left and right in FIG. 3) direction of the guide rail 21a, and a pair of inverted L-shaped levers 26a and 26a are back-to-back at the front and rear ends of the bracket 25a. The tension rollers 28a and 28a are rotatably attached to the lower ends of the levers 26a and 26a through the pins 27a.
[0013]
The endless conveyor belt 22a is wound along the upper and lower surfaces of the guide rail 21a, and both front and rear (left and right in FIG. 3) ends are wound around the toothed pulleys 23a and 23a. The upper front and rear intermediate portions are wound from below the tension rollers 28a, 28a, and then wound around the toothed drive pulley 29a on the upper side. The toothed drive pulley 29a is attached to the left and right moving body 16a side via a bracket 30a and is driven by a motor (not shown).
[0014]
A pair of stoppers 31a and 31a are attached downward to the front and rear (left and right in FIG. 3) ends of the lower portion of the bracket 30a, and the upper swinging ends of the levers 26a and 26a are brought into contact with the stoppers 31a and 31a. As a result, when the transport main body portion 20a is moved upward by the up-and-down moving body 18a and thus moved to the toothed drive pulley 29a side, the levers 26a and 26a are tensioned around the pins 27a and 27a by the stoppers 31a and 31a. The rollers 28a and 28a are rotated in a direction in which the rollers 28a and 28a approach each other, and the tension rollers 28a and 28a prevent the transport belt 22a from being loosened. In this case, as shown in FIG. 3, the conveyance main body 20a of the front processing unit 2-1 extends the left (front) side largely to the left with respect to the column 3, while the rear processing unit As shown in FIG. 4, the conveyance main body portion 20 a ′ of 2-2 extends rightward (rear part) side to the right with respect to the column 3 ′, and thereby each conveyance main body portion 20 a, 20 a ′. Are opposed in parallel to the left and right with the same longitudinal length.
[0015]
The front machining unit 2-1 and the rear machining unit 2-2 configured as described above are attached to the machine base 1 in the front-rear direction, and the rear machining unit 2-2 is installed as shown in FIG. It is biased (moved) to the left with respect to the front processing unit 2-1, and the main transfer parts 20a 'and 20b' of the rear processing unit 2-2 are brought close to the fixed ruler 35 on the left side to perform front processing. The transport main body portions 20a and 20b of the unit 2-1 are brought close to the movable ruler 36 on the right side, and the left and right sides of the printed circuit board W are sandwiched between the upper and lower transport main body portions 20a, 20a ′, 20b and 20b ′. This is conveyed from the front side toward the rear side.
[0016]
Both the fixed ruler 35 and the movable ruler 36 are opposed to the left and right in the same longitudinal direction as the main conveying parts 20a, 20b, 20a ′, 20b ′, and restrict the horizontal movement of the printed circuit board W. The fixed ruler 35 is a machine ruler. The movable ruler 36 is fixed to the base 1 side, and is supported on the base 1 side by a servo motor or the like so that it can be moved left and right.
[0017]
Since the present invention has the above-described configuration, the vertical rotary cutters 13a and 13b (13a ′ and 13b ′) of the front and rear processing units 2-1 and 2-2 are transferred to the transport main body portions 20a and 20b (20a′20b ′). When the conveying devices 15a and 15b (15a 'and 15b') are moved in the left and right direction in this state, the left and right moving bodies 16a and 16b and the up and down moving bodies 18a and 18b are notched (a). Through the rotary cutters 13a and 13b, and the conveyance main body portions 20a and 20b (20a 'and 20b') are positioned on the left side or the right side of the rotary cutters 13a and 13b. Become.
[0018]
Thereby, the groove processing of the printed circuit board W by the rotary cutters 13a and 13b can be performed from either the outside or the inside of the transport main body portions 20a and 20b (20a ′ and 20b ′). When the narrow printed board W is to be grooved, the right side of the rotary cutters 13a and 13b is used to transfer the main processing units 20a and 20b of the right side processing unit, in this example, the front side processing unit 2-1. The movable ruler 36 can be moved to the left by passing between the main conveying parts 20a and 20b, and the small printed board W can be moved to the left (front). And the upper and lower cutter units 10a, 10b (10a ', 10b') of the front and rear processing units 2-1, 2-2, while being held and transferred only by the transfer main body parts 20a ', 20b' on the part) side. W groove processing can be performed.
[0019]
In the present invention, the lower cutter device 10b (10b ′) may be omitted, and the groove processing may be performed only by the above-described cutter device 10a (10a ′). Further, in this case, the lower conveying device 15b (15b ′) may be a belt conveyor or a roller conveyor which cannot be moved left and right and up and down.
[0020]
【The invention's effect】
As is apparent from the above description, the present invention has processing units arranged at the front and back, and a transport device for each processing unit is provided so as to be movable to the left and right with respect to the rotary cutter of each processing unit. The conveyor belt can be switched to the left and right positions with respect to the rotary cutter, and the printed circuit board can be grooved at an arbitrary position. The effect which can convey stably is produced.
