When the carrying-in conveyor 16 sends out the received work Wa, the next work Wa is transported to the carrying-in position at the same time, and the next work Wd is loaded to the inspection position of the inspecting machine body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a workpiece feeding and discharging system for a gear inspection machine.

b. Conventional technology Conventionally, in order to inspect the gear meshing sound of a workpiece (final gear), which is a gear to be inspected, using a gear inspection machine, for example, the workpiece and a reference gear (master gear) are rotated in a meshed state. At this time, the distance between gear axes, etc. is measured with an electronic micrometer, and after amplifying the output of the electronic micrometer with an amplifier, it is converted into a digital signal using a digital converter.
By comparing this digital signal with standard values for tooth vibration, dents, etc., abnormalities such as tooth vibration, dents, etc. on the workpiece are detected.

Then, all the workpieces that have been inspected by the inspection machine are delivered onto the same conveyor, and are sorted into acceptable and rejected products by a sorting machine installed at the rear of the conveyor.
Alternatively, acceptable products and rejected products are delivered to separate conveyors using an X-Y type loader for sorting.

C9 Problems to be Solved by the Invention - However, in the above-mentioned gear meshing sound inspection process, a workpiece sorter is used to classify the workpieces into three types: acceptable products, rejected products with unevenness, and rejected products with dents. According to this method, the sorting machine becomes complicated and the equipment cost increases. In addition, according to this method, the inspection results of the previous work must be memorized even while the next work is being inspected, from the time the work is delivered to the container until the sorting is completed, making the control circuit complicated. It had the disadvantage of becoming

Further, around the inspection machine main body 1, a carry-in device I2 and a carry-out device 13 are arranged in association with the loader 3.

Carrying equipment! F1.2 is installed on the front side of the inspection machine main body 1, and transports the workpiece W to be inspected at a predetermined interval to the loading position (and passing workpiece loading position) where a vertically movable striker 14 is provided. It has a drive device 15 and a carry-in conveyor belt 16.

The carry-out device 13 is installed on the side of the inspection machine main body 1, and is used to transport the workpiece W after the inspection to the end opposite to the inspection machine main body 1, and is driven by a drive device (not shown). It is equipped with two unloading conveyors 17.1819. In other words, these carry-out conveyors include a first carry-out bucket conveyor 7 for carrying the accepted work-a, a second carry-out slat conveyor I8 for carrying the rejected work Wb with dents, and a 1st carry-out bucket conveyor I8 for carrying the dented rejected work-○. Consists of 3 unloading slat conveyors 19, in this order the front side (lower side in Figure 1)
