PURPOSE:To make the follow-up moving direction of a push bar convertible with simple operation, by installing each cam roller in both upper and lower parts of a vertical shaft at the rear end of a rocking bar, moving this vertical shaft up and down, and engaging it with two upper and lower cam plates in a selective manner. CONSTITUTION:In a block 22 to which the rear end of a rocking bar 17 is attached, there is provided with a rearward projecting part 23. In this part, a vertical shaft 26 fitted with cam rollers 24 and 25 at both vertical ends is installed so as to be fixable with a spring pin 27 at two upper and lower positions. In this vertical shaft 26, there are provided with projections 28 and 29 so as to perform alignment easily, and two upper and lower cam plates 30 and 31 are horizontally attached onto a machine frame in and around the rear end part of the rocking lever 17. These cam plates 30 and 31 are used in accord with either of the c.w. or c.c.w. driving direction of a cross conveyor. Therefore, with the spring pin 27 attached or detached, these cam rollers 24 and 25 are able to engage either of the upper and lower cam plate, thus the follow-up moving direction of a push bar is simple convertible. |
