As shown in FIG. 1 to FIG. 3, when most of the devices of the present invention in which a set of pedals are installed between two belts 2 are completely assembled, a method of setting up such pedals in a group between two belts 2 includes the following steps:

Step 1: The belts 2 are respectively set on the runner groups 12 and the tension groups 18 are activated. Through the tension groups 18 (pressure cylinders), the upper rollers 122 can be made to extend. The distance from the corresponding lower runner 121 becomes larger, and the belts 2 can be adjusted to have a predetermined tension.

Step 2: Start the power source 14 and rotate two of the lower wheels 121 and the detent wheels 13 at the same time. The lower wheels 121 drive the belts 2 in a running direction (clockwise as shown in FIG. 1) Direction) turns intermittently.

Step 3: When the belts 2 stop:

(1) The first installation station 15 performs: As shown in FIG. 1, the screws 103 of the pedals 1 are passed through the perforations 202 of the belts 2, and the body 101 is abutted against the outside of the belts 2. Side, and using the screws 103 to pass through the perforations 202, the pedals 1 can be temporarily positioned relative to the belts 2. When the detent wheels 13 continue to drive the belts 2 to rotate intermittently in the running direction, the pedals 1 can be guided smoothly by the guide portion 173 of the guides 17 and can smoothly move. As the belts 2 move below the lower runners 121 and the rollers 172 can be used to smoothly move to the second installation station 16.

(2) The second installation station 16 performs: the pedals 1 that have been moved to the second installation station 16, the screws 103 substantially correspond to the pneumatic rotary tool 51 of the reclaiming device 50. At this time, the pushing units 60 are extended to push up the pedal 1 and the belts 2 of the nut 4 to be locked upward, and make the belts 2 relative to the Y along the second axis. The base 11 is positioned. With reference to FIGS. 7 and 9, the second magnet 252 of the loading part 25 can be sent to the second installation station by using the cooperation of the lifting and lowering cylinder 21 and the laterally moving cylinder 23 of the plywood feeding unit 20. 16 (can be fed through the vibrating feeder, not shown), take up the clamp plate 3 when the clamp plate 3 is already located above the screws 103, start the pushing cylinder 253 (as shown by the solid line to the imaginary line in FIG. 9 ), And the plywood 3 is placed toward the belts 2, and the screws 103 are passed through the through holes 301. Meanwhile, as shown in FIG. 8, the nut feeding units 2 sequentially convey the nut 4 to The second installation station 16. At the same time, the third driving member 47 of the driving unit 40 is activated to drive the pneumatic rotary tool 51 from a first rising position (see working step A of FIG. 8) to a first lowering position (see FIG. 8). Working step B), after taking up the nut 4, the driving unit 40 drives the reclaiming unit 50 to return from the first lowering position to the first raising position, and uses the first magnet 513 at the reclaiming end 512 Pick up the nut 4 that has reached the end of the feeding track 312 (see working step C of FIG. 8), and then start the second driving member 46 and the first driving member 43 to enable the pneumatic rotary tool 51 to be lifted The nut 4 moves toward the screws 103 located at the second installation station 16, so that the take-up end 512 approaches the screws 103, and the nuts 4 abut against the top of the corresponding screws 103. Then, The picking unit 50 rotates the picked nut 4 relative to the screws 103, locks the nut 4 to the screws 103, and clamps the clamping plate 3 on the belts 2. Finally, The driving unit 40 drives the reclaiming unit 50 away from the screws 103 (see FIG. 10).

Step 4: Repeat steps 2 to 3, and the pedals 1 can be continuously locked and fixed on the belts 2.

Step 5: Start the tension group 1 again. Through the tension group 18 (pressure cylinder) to retract, the distance between the upper rollers 122 and the corresponding lower rollers 121 can be reduced. When the tension of the belt 2 becomes small, the belts 2 on which the pedals 1 have been assembled can be detached from the runners 12 respectively.

Therefore, by using the method and the device for setting most pedal sets between two belts of the present invention, it is possible to set the pedals 1 on the belts 2 in a continuous and consistent automatic operation, which can increase productivity and reduce labor costs. Purpose.

It is worth mentioning that in the above embodiment of the method in which the majority of pedal sets of the present invention are provided between two belts, when the belts 2 are stopped in step three, the pushing units 60 are extended, and The pedal 1 and the belts 2 to be locked with the nut 4 are pushed upward. However, because the main function of the push unit 60 is to provide a support when the pedal 1 is locked to the belt 2, as long as the belt is attached and the lock nut is in front, the push unit 60 can be operated to extend. Action and push up on these belts 2. Generally, the pushing unit 60 can be driven after the belt 2 is hung and before the tension group 18 performs tension tensioning or after tension tensioning.

In summary, the method and device for setting most pedal sets between two belts of the present invention can be applied to the automatic assembly operation of the pedals of the belt of the belt-type treadmill, and can indeed achieve the purpose of the present invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
