In order to make the arm extendable and contractable, the base of the telescopic arm having an indicator at the distal end is attached to the motor so as to rotate and scan the component pick-up surface. Motor control means for controlling the rotation of the motor so as to be able to face the unit parts shelf to be taken out, and arm expansion / contraction control means for controlling the expansion and contraction of the arm so that the indicating unit faces the unit parts shelf to be taken out at the position where the rotation is controlled. Attach.

[Action]

In response to the production instruction signal, the motor control means controls the rotation of the arm to a rotation position facing the corresponding unit shelf. Further, the light emission control means also causes the light emitting element facing the corresponding unit component shelf to emit light in response to the production instruction signal.

When making the arm extendable and contractible, the motor is controlled to rotate so that the indicating unit can face the unit parts shelf to be taken out in response to the production instruction signal, and the arm is controlled to extend and contract at this rotationally controlled position. Control is performed so that the indicating unit faces the unit parts shelf to be taken out.

〔Example〕

FIG. 1 shows a component removal instruction apparatus according to one embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a parts shelf provided with 4 × 4 unit parts shelves, and a motor 5 is mounted at the center thereof. This motor has a base end of the arm 6 arranged light-emitting elements 8 _{1-8 3} is attached, has become possible recoverable rotated by a certain angle from the original position by the coil spring 7. The light emitting element 8 _{1-8 3,} light emission control circuit 18 to emit light either in response to a light emission instruction signal is supplied. The motor 5 has a rotation position sensor and a motor control circuit 19 for driving the motor 5 to rotate to an angle corresponding to the input rotation position signal.

Reference numeral 10 denotes a CPU provided with an I / O port 11, a ROM 12 storing a program, a nonvolatile memory for teaching data, a RAM 13 having a work area, and the like. The CPU 10 cooperates with a light emission control circuit 18 and a motor control circuit 19. Together, they constitute the motor rotation control means and the light emission control means of the present invention. In the teaching pendant 2, this CPU is previously taught which unit component shelf should be instructed for the specification instructed on the production line, and is stored in the RAM 13. The RAM also stores motor rotation position data and light emitting element instruction data corresponding to the arrangement of all unit component shelves in the component shelf 1 in the same manner. Then, in response to the production instruction signal transmitted from the production line, a motor rotation signal and a light emission control signal that are adapted to the arrangement position of the corresponding unit component shelf on the component shelf 1 are sequentially output with reference to the teaching data.

The operation of the component pointing device thus configured is as follows.

Every time the production instruction signal is input, the CPU 10 decodes the specification and outputs the corresponding motor rotation signal and light emission control signal. For example, when to instruct the unit component shelf 1 _1, to the light-emitting element ₈₁ at the location of the illustrated lighting predetermined time. Next, when to instruct the unit parts shelves 1 _2, to light the light emitting element ₈₁ to rotate the arm 6 along the rotational path A to × mark P _1.
Further, when to instruct the unit parts shelves 1 ₃ lights the light-emitting element ₈₁ at a position where the tip of the arm 6 reaches the floor surface. When to instruct the unit parts shelves 1 _4, turns on the light emitting element 8 ₃ rotates the arm 6 in a substantially horizontal position, if it is to be instructed to the unit component shelf 1 _5, slightly above the position shown is rotated to turn on the light-emitting element ₈₂ at its bottom position.

Thus rotation controls the rotation scannable arm 6 to the designation position in the range of arrow A, the light emitting element ₈₁ of one each time
8 ₃ by lighting the can instruct all the units parts shelves. If the arm 6 is in the way when taking out a part or pulling out a pallet therein, the arm 6 is automatically returned by rotating the arm 6 against the spring force.

In the above-described embodiment, if the arm 6 is rotated until the attached limit switch is actuated each time a component is taken out, the component take-out can be automatically confirmed by the detection signal. In response, the arm 6 can be returned to the original rotational position each time.

As shown in FIG. 2, so the arms 36 can complete rotation, the densely arranging the light emitting element can unify the instruction signal to the to all parts shelves for example, the center position P _C and the like. At this time, a degoder circuit is attached to each light emitting element without wiring one line for each light emitting element in addition to a common line, thereby reducing the number of wires required for sending a binary signal. You can also. Further, in order to indicate the unified position without lifting the component shelf in this way, it is conceivable to provide a joint on the arm 36 to perform bending control. Further, as shown in FIG.
37 need not necessarily be located in the center of the parts shelf. Further, in these embodiments, the length of the arm and the number of light emitting elements are given a margin, and the CPU 10 is also provided in advance or later, so that it is possible to easily cope with the addition of a shelf due to a process change. it can. Further, such an arm with a motor can be easily attached to and detached from the component shelf 1.

FIGS. 4 and 5 show still another embodiment of the present invention, in which an arm 40 is provided with a fifth stage sleeve 40 ₅ provided with a pointer 41 at the tip and a first stage mounted on a motor 45. including sleeve 40 ₁ is telescopically formed five stages sleeve type. Sleeve 40 ₁ can be rotated up to a predetermined angle so as to be restored in same way spring 46. As shown in FIG. 5, these sleeves replace the light emission control circuit 18 of FIG.
It is controlled by arm extension / contraction control means using the wire 42. That is, the wire 42 is wound around a winding drum 47 that is driven to rotate by a motor 48, and the motor 48 is controlled by a motor control circuit 49 so that the hands 41 indicate the unit shelves to be taken out. Take or rewind.

〔The invention's effect〕

As described above, according to the present invention, the number of parts and the number of wirings of the apparatus can be reduced and the parts shelf can be directly specified, which is extremely advantageous in manufacturing cost. It is possible to easily cope with a process change or an addition of a component shelf only by changing the control circuit portion.
Since the device only supports the base of the arm, it can be detachably mounted on the component shelf.
