スプリングである。The rear end portion of the lug stand-up linear guide portion 33c and the front end portion of the lug guide rail 34 are provided in an overlapped state with a predetermined length, and the connecting surfaces of the conveying lugs that are slidably contacted with each other have no step. It is configured to be a surface. The movement adjustment of the lug standing guide body 33 is performed within the range of the overlap with respect to the lug guide rail 34. Further, the lug standing guide body 33 is provided so as to be slidable forward and backward with respect to the lug guide rail 34 fixed to the transport case 22 together with the sprocket shaft 27, and the tension of the transport chain 21 wound around the sprocket 23. It is structured so that it can be adjusted. Reference numeral 35 is a bearing body that holds the sprocket shaft 27 as a bearing, 36 is a tension rod, and 37 is a tension spring.

図ることができる。The lug guide rail 34 is also made of resin, and the rear end portion (conveying end side portion) of the rail 34 is bifurcated 34a, 34b so as to sandwich the drive sprocket 24. The bifurcated portions 34a and 34b are thin-walled so as to have appropriate elasticity. Therefore, even if the lug is overloaded during operation, breakage of the lug can be prevented by the escape of the forked portions 34a and 34b, and the durability can be improved.

低下並びに摩耗の減少を図ることができる。Conventionally, the lug stand-up guide body around the sprocket shaft center uses a roller which rotates integrally with the sprocket. Therefore, since the gap between the roll and the roller is opened, noise is generated when the roll comes into contact with the roll. Further, since the lug once falls between the roller and the lug guide, noise is generated and a large impact is generated, which may cause early wear and accidental damage. According to the above-mentioned lug standing guide body 33, the lug standing start guide portion 33a and the lug standing arc guide portion 33b.
Since the lug rising straight line guide portion 33c is integrally connected, the lug rising guide is smooth, and noise and wear can be reduced.
