Description

[Detailed Description of the Invention] The present invention relates to an information processing cable connection device for a rail type universal parallel ruler.

The amount of movement of the scale in a rail type universal parallel ruler is the amount of movement of the horizontal rail moving body relative to the horizontal rail in the horizontal direction, and the amount of movement of the vertical rail moving body relative to the vertical rail in the vertical direction, so for example, A light-emitting element and a light-receiving element on a moving object are placed opposite to equally spaced slits provided along the rail, and the amount of movement of the moving object is electrically detected based on the output signal of the light-receiving element, and the amount of movement is digitally detected. It is possible to display numerical values. In this case, these movement amount display parts may be displayed simultaneously on the head section, on a connecting part integrated with the moving body, or on a vertical rail, or they may be moved in advance to match the actual scale movement detection value. A control unit is installed in one place, such as on the head, to compare the set values stored in It is also convenient for drafting work to provide an information processing cable for connecting the vertical rail moving body and the horizontal rail moving body. However,
If the information processing cable is connected outside the vertical rail, the cable tends to slack as the vertical rail moving body moves, which not only hinders the drafting work but also causes wire breakage.

Therefore, the present invention aims to provide an information processing cable connecting device for a rail-type flexible parallel ruler that allows information processing cables to be connected within the vertical rail without changing the conventional vertical rail format. The gist of the patent is as stated in the claims for utility model registration.

The apparatus of the present invention will be explained in detail below with reference to the illustrated embodiment. In FIG. 1, numeral 1 denotes a drawing board, which is generally installed at an angle with respect to the horizontal. 2 is drawing board 1
A horizontal rail fixed along the upper edge of the horizontal rail movably guides the horizontal rail moving body 3 via rollers. The horizontal rail moving body 3 is provided with a vertical rail 5 via a connecting case 4 so as to maintain a perpendicular relationship to the horizontal rail 2 and move on the drawing board 1. Vertical rail 5
A vertical rail moving body 6 is movably guided through rollers, and a scale operating head portion 7 is connected to the vertical rail moving body 6 via a parallel lifting link mechanism or the like. 8a and 8b are scales operated on the drawing board 1 by the head section 7. As shown in FIG. 2, the vertical rail 5 is divided into two sections, upper and lower, and the hollow interior of the upper section serves as a weight running frame 9 for running a balance weight. Reference numeral 10 denotes a balance weight, which is configured to be able to move freely within the weight traveling frame 9 by means of its traveling rollers 11. At the bottom of the vertical rail 5 is a rail frame 12 for the rollers of the vertical rail moving body 6.
The roller 1 shown in FIGS. 3 and 4 is provided with
3 are rotatably engaged with these rail frames 12 and guide the vertical rail moving body 6 along the lower surface of the vertical rail 5. At both upper and lower ends of the vertical rail 5, cable guide pulleys 14 and 15 having rotating surfaces spanning the upper and lower sections are rotatably provided, and the cable guide pulley 14 at the upper end has a central guide groove 14a.
A wire rope 16 with one end connected to the balance weight 10 is wound and the other end is fixed to the attachment part 6a of the vertical rail moving body 6,
Two wire ropes 17, one end of which is fixed to the balance weight 10 through the guide grooves 15a at both ends, are wound around the cable guide pulley 15 at the other end. It is fixed to the mounting part 6b. Therefore, the vertical rail moving body 6 and the balance weight 10 are connected to the wire rope 1.
6 and 17, and are configured to interlock along the vertical rail 5. The balance weight 10 is attached to a head portion 7 provided on the vertical rail moving body 6.
It is constructed so that the weight can be balanced. Although not shown in the figure, a linear scale consisting of equally spaced slits, etc. is provided along the longitudinal direction of the horizontal rail 2 and vertical rail 5, and the amount of movement of the light emitting element, light receiving element, etc. relative to the linear scale is determined. By providing the detection section on the horizontal rail moving body 3 and the vertical rail moving body 6, it is possible to detect the amount of movement of the moving body along the rail. It is possible to provide an electromagnetic brake device that acts on the moving body, and to operate the electromagnetic brake device to stop the movable body at a predetermined position by operating a keyboard-type control unit provided on the head portion or the like.

Here, the device of the present invention uses a flat cable as an information processing cable connecting between the horizontal rail moving body 3 and the vertical rail moving body 6. The cable 18 is introduced into the weight traveling frame 9 from the upper end of the vertical rail 5, and the cable 18 is inserted into the weight traveling frame 9, leaving a length sufficient for the traveling distance of the balance weight 10.
Attach to. In the case of the embodiment, information processing cable 1
8 is provided with a U-shaped folded portion 18a in front of the center of the balance weight 10 passing above it, and then a fixing portion 18b is provided on the upper surface of the balance weight 10. The folded portion 18a and the fixed portion 18
b is configured to pass between the running roller 11 of the balance weight 10 and the two wire ropes 17. On the other hand, the information processing cable 18 extends from the fixed part 18b toward the cable guide pulley 14 at the upper end of the vertical rail 5, and is introduced into the rail frame 12 of the vertical rail 5 after being wound around the cable guide pulley 14. It is stretched along the upper surface of the lower opening edge 12a of the rail frame 12, and its end is connected to the vertical rail moving body 6.
It is attached to the cable connection part 6c of.

In addition, the balance weight 10 and the vertical rail moving body 6
The information processing cable between the two may be connected via the lower cable guide pulley 15. Further, it is also possible to omit the wire rope 16 or 17 that overlaps the information processing cable 18.

In the embodiment configured as described above, when the vertical rail moving body 6 is moved along the vertical rail 5, the balance weight 10 connected to the wire ropes 16 and 17 is moved in the weight traveling frame 9 in conjunction with the movement. At this time, the information processing cable 18 stretched between the vertical rail moving body 6 and the balance weight 10 via the upper cable guide pulley 14 maintains a connected state in the same way as the wire rope 16. Further, the information processing cable 18 introduced from the horizontal rail moving body 3 into the weight traveling frame 9 and fixed to the balance weight 10 is connected to the leftover folded part when the balance weight 10 approaches the upper end of the vertical rail 5. 18a is stored in the weight traveling frame 9 below the balance weight 10, and when the balance weight 10 approaches the lower end of the vertical rail 5,
The information processing cable of the folded part 18a is stretched through the upper center of the balance weight 10,
In either case, the connection state of the information processing cable between the horizontal rail moving body 3 and the balance weight 10 will be maintained.

As described above, according to the device of the present invention, the information processing cable connected to the horizontal rail moving body is introduced into the weight traveling frame from the upper end of the vertical rail, and is given slack so as not to obstruct the traveling of the balance weight. Since the configuration is such that it is first connected to the balance weight and then operably connected to the vertical rail moving body via a cable guide pulley provided at one end of the vertical rail, there is no need to make any changes to the conventional vertical rail format. Information processing cables can be connected within the vertical rails, and there is no risk of interfering with drafting work or disconnection, and the original purpose can be achieved.
