つた。 This type of safety device includes a light emitter and a light receiver that are located at appropriate positions in the press equipment and are arranged opposite to each other. If the wire is broken, it will be detected electrically. If the worker's hand is in a dangerous position when operating the press device, the light beam from the emitter to the receiver will be cut off by the worker's hand, thereby preventing the press device from operating. blocked. However, in conventional safety devices, the installation position of the emitter and receiver can be adjusted both horizontally and vertically in order to widen the sensing range, but adjusting only in these two directions can cause problems such as press work. In the case of small-sized presses, there were drawbacks such as insufficient sensing when reaching deep into the press equipment, and depending on the shape of the mold, the light beam could be cut off by the mold.

受光器には複数の受光部がある。 This press device generally has a light projector 11 on one side and a light receiver 12 on the opposite side facing each other at the height of the movement range of the upper mold 3. These light emitter 11 and light receiver 12 are each provided parallel to the side surface so as to be freely adjustable in the lateral and vertical directions. Therefore, the floodlight 11 is mounted on an upright support 1 as shown in FIGS. 3 and 4.
3, and a long hole 13' formed in the column 13.
It can be freely adjusted up and down along the support column by means of adjustment bolts 14. In addition, the support column 13 is freely adjustable on a horizontal guide 15 attached to the frame 1 or a bracket fixed to the frame 1, and for example, as shown in the figure, a leg 16 projecting laterally is provided at the lower end of the support column 13, Its legs 16
is fitted into the horizontal guide 15.
Similar to the emitter 11, the receiver 12 also has an upright support 1.
3 and horizontal guides 15. In order to ensure that the emitter 11 and the receiver 12 are accurately aligned with each other, the column 13 and the horizontal guide 15 or leg 16 are respectively graduated. Note that, as in the past, in most cases, the projector is provided with a plurality of optical axes, and correspondingly, the light receiver is provided with a plurality of light receiving sections.
