Abstract

(57) [Summary] [Object] The present invention is characterized in that full bobbins can be arranged and packed one by one from the bottom to the top of the collection box without any gap. [Structure] A full bobbin sent by a conveyor is changed in direction by a guide of a chute, kept horizontal by a straightening plate of the chute 6, and dropped into a recovery box. The chute is speed-controlled according to the number of full bobbins detected by an optical sensor installed near the conveyor, and when the proximity switch detects the end of the chute, the recovery box mounting table with the recovery box is one step higher. Can be lowered. Therefore, the chute is reversed and moved in the opposite direction, and the full bobbins sent by the conveyor are sequentially inserted into the next stage. Then, when a full number of bobbins are inserted into the collection box up to a predetermined number of stages, the collection box mounting table is lowered to a position where the collection box can be taken out, and the process ends. In this way, since the full bobbins are sequentially inserted into the collection box, it is possible to fill them without manpower, and it is possible to eliminate the manpower shortage.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. First, when the activation switch 35 is turned on, the CPU 34 determines whether or not the limit switch 32 operates and the collection box mounting base 30 is at a predetermined position,
If the limit switch 32 is not operating, it waits until the limit switch 32 is turned on (step 1).

Then, when the limit switch 32 is turned on and the collecting box 31 reaches a predetermined position, a full bobbin collecting conveyor (not shown) of the auto doffer is activated (step 2).

Next, the conveyor drive motor 4 is activated to drive the conveyor 3 (step 3).

It is determined whether or not the full bobbin 20 has been detected by passing between the light emitting element 18 and the light receiving element 19, and the process waits until the full bobbin 20 is detected (step 4).

When the optical sensor detects the full bobbin 20, the traverse motor 16 is normally rotated to move the chute 6 in the same direction as the conveyor 3, that is, in the positive direction (step 5).

In this case, the moving speed of the chute 6 is controlled according to the number of full bobbins 20 detected by the optical sensor.

Then, it is judged whether or not the proximity switch 25 has been operated by the operating member 24 of the chute 6 (step 6), and the chute 6 moves in the forward direction until the proximity switch 25 is operated.

When the proximity switch 25 is actuated, the CPU 34 determines whether the collection box 31 has a predetermined number of full bobbins 20 according to the number of full bobbins 20 detected by the optical sensor (step 7).

If the collection box 31 does not have a predetermined number of stages, the mounting table drive motor 29 is driven to collect the collection box mounting table 3
Decrease 0 by one step (step 8).

Then, the traverse motor 16 is rotated in the reverse direction to move the chute 6 in the reverse direction (step 9).

Here, the CPU 34 determines whether or not the proximity switch 26 has operated, and waits until the proximity switch 26 operates (step 10).

When the proximity switch 26 operates, the collection box 3
It is determined whether or not the number of full bobbins 20 has reached a predetermined number in 1 (step 11).

If the predetermined number of steps is not entered, the mounting table drive motor 29 is driven to lower the collection box mounting table 30 by one step (step 12).

Then, the process jumps to step 5 and moves until the proximity switch 25 operates, and when the proximity switch 25 operates, it is judged whether or not the full bobbin 20 has entered a predetermined number of stages in the collection box 31, and if the predetermined number of steps has been entered, The collection box mounting base 30 is moved to a position where the collection box 31 can be taken out (step 13).

Here, it is judged whether or not the limit switch 33 has operated (step 14), and if not operating, it waits until it operates, and if the limit switch 33 operates, the mounting table drive motor 29 is stopped. The collection end indicator lamp 39 is turned on to notify the end of collection.

The optical sensor including the light emitting element 18 and the light receiving element 19 plays a role of counting the number of collected full bobbins 20 and blocking the flow of the full bobbins 20 (trouble detection).

If the light from the light emitting element 18 is blocked for a predetermined time or longer, the CPU 34 determines that the flow of the full bobbin 20 is blocked and stops the apparatus.

Further, if the full bobbin 20 does not block the light from the light emitting element 18 for a predetermined time or more, it means that the recovery device of the auto doffer has a trouble or the recovery of the full bobbin 20 is completed. In the case of, the equipment is repaired, and when the collection is completed, the equipment is stopped.

Limit switches can be used instead of the proximity switches 25 and 26, and proximity switches can be used instead of the limit switches 32 and 33.
