SU63364A1 - Safety device for moving parts of machines against tilting fences on the go - Google Patents

Description

The invention relates to safety devices that block access to moving parts of machines on the go in dangerous places.

The fixture consists of a rotating, slotted disc, driven from any part of the machine, and a locking hook on the fence.

The essence of the invention is that the locking hook of the guard, or the door of any mechanism or machine, is inserted through the slot into the rotating disk (cup) in a resting or running state of the machine; The output of this hook from a rotating disk is possible only after a complete stop of the machine.

In FIG. 1 is a side view in section of a tool for moving parts of a machine; FIG. 2 is a top view of the fixture of FIG. 1, fig. 3 - side view of the locking hook in a different design; FIG. 4 shows a safety device in section in another embodiment; FIG. 5 is a front view of the fixture of FIG. four.

In housing 1 (FNG. 1), mounted on bracket 2 to the frame of the machine, spindle 3 mounted on ball bearings, carrying a cup disk 4 and block 5 on itself. Disk 4 is mounted on spindle 3 freely and is driven by a pin 6 through pin 7 The pin b is pressed in the washer 8, tightly seated on the spindle 3, and the pin 7 is integral with the disk 4. The disk 4 has a slot 9 and with a counterweight 10; the latter establishes the disk 4 with a slot 9 above the locking hook 11 at the time of stopping the machine, thereby achieving the ability to remove the hook from the disk cavity and remove the guard.

FIG. 3 depicts a hinged type locking hook, the structure of which allows the cover to be closed while the machine is moving. The dog 12 of the locking hook 13 is articulated and spring-loaded, which makes it possible for it to deflect when entering the disk cavity as it rotates.

FIG. 4 and 5 depict the safety device in a different design. A locking hook 14 is inserted into the cavity of the disk 15 according to the invention in the direction of the axis of rotation of the disk. The device in this design of the design, as well as in the previous one, has a hollow slatted disk 15 with a slot 16, driven by a block

17from any part of the machine with the help of driver pins

18 and 19. Disk Chy and block 17 are movably mounted on a fixed spindle 20 of the machine.
