ある。(Description of Embodiment) Hereinafter, one embodiment of the present invention will be described based on FIGS. 3 to 5. The chuck body 1 has an upper side 1a,
It has a U-shaped cross section with a lower side 1b, and the lower side 1b constitutes one chuck pawl as a fixed pawl 41 . The movable claw 42 constituting the other chuck claw is tapered to match the taper of the spool S, as shown, and is directly connected to the drive shaft 3 passing through the upper side 1a of the chuck body 1. The chuck pawl of the present invention is thus composed of a fixed pawl 41 on the main body side and a movable pawl 42 connected to the drive shaft 3, and the chuck pawl S is connected to the spool S with its axis pointing in the U-shaped opening direction of the chuck body 1. The structure is such that the check is perpendicular to the vertical direction. When releasing the spool, as shown in FIG. 5, the hollow shaft 2 is swung in the direction opposite to the opening direction of the chuck body, and the chuck pawl 4 is opened by moving the movable pawl 42 upward. The spool S is released, allowed to fall under its own weight, and discharged to a predetermined location.

きる。(Effects of the Invention) As is clear from the above embodiments, the present invention is a horizontal chuck in which the chuck pawl has the same slope as the taper of the spool. When the spool is released, the opening of the chuck pawl faces downward, allowing reliable spool discharge. Therefore, it is possible to reliably prevent spool chuck errors and spool drop errors during continuous automatic operation of the resin molding machine.
