ben çözüm buldum:

from scrapy.utils.project import get_project_settings 
from scrapy.crawler import CrawlerRunner 
from twisted.internet import reactor 
from twisted.internet import task 


timeout = 60 


def run_spider(): 
    l.stop() 
    runner = CrawlerRunner(get_project_settings()) 
    d = runner.crawl('spider_name') 
    d.addBoth(lambda _: l.start(timeout, False)) 


l = task.LoopingCall(run_spider) 
l.start(timeout) 

reactor.run()
