Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-array rotation speed indicator for use as an ink adjustment knob for a letterpress rotary press or an offset form rotary press.

[Conventional technology]

This type of rotational speed indicator rotatably supports a weight oriented in the direction of gravity within a case, and a scale plate is fixed to the weight and rotates with respect to the weight as the case rotates. It is common to have a pointer and a handle fixed to the case.

[Problem that the invention attempts to solve]

The above-mentioned weight-type rotational speed indicator has restrictions on the mounting direction, and it is necessary to tilt the entire device at approximately 60 degrees from the side so that the weight points in the direction of gravity, and it cannot be mounted vertically. The present invention aims to eliminate the above defects.

[Means to solve problems]

In order to achieve the above object, the present invention includes a cylindrical handle 2 for attachment to a rotating member, a pair of magnets 18 and 19 located on both sides, and rotatably supported within the handle 2. Reference body 14
a scale plate 16 fixed to the reference body 14; a shaft 10 fixed in the handle 2; and a pointer 32 attached to a gear 30 rotatably supported by the shaft 10. It consists of a gear mechanism that transmits the rotational movement of the shaft body 10 relative to the reference body 14 to the pointer 32 at a predetermined reduction ratio.

[Effect]

A handle 2 is attached to the rotating member adjacent to the handle of another rotation speed indicator. At this time, the reference body 1
Even if the center axis of rotation of 4 is perpendicular, the reference body 14
are oriented in a predetermined direction by magnets in adjacent handles. When the handle 2 is rotated, this rotation is transmitted to the pointer 32 by a gear mechanism, and the handle 2
a scale plate 16 whose rotation amount is interlocked with the reference body 14;
This is indicated by interaction with the pointer 32 opposite thereto.

〔Example〕

The configuration of the present invention will be described below with reference to embodiments shown in the accompanying drawings. 2 is a cylindrical handle;
A transparent cover plate 8 made of a glass plate is fitted into one part of the handle 2 and positioned by a ring. Reference numeral 10 denotes a shaft body fixed to the partition wall of the handle 2 with a nut, and a reference body 14 is rotatably fitted to the outer peripheral surface of the large diameter portion of the shaft body via a ball bearing 12. The reference body 1
A scale plate 16 is fixed to 4 by a mounting shaft 15. A pair of rare earth high performance magnets 18 and 19 are fixed to both sides of the reference body 14 by adhesive. Reference numeral 20 denotes a shaft body erected on the reference body 14, and a two-step gear having a large diameter gear 22 and a small diameter gear 24 formed thereon is rotatably fitted into the shaft body. The large diameter gear 22 meshes with a small gear 26 fixed to the small diameter portion of the shaft body 10. The small gear 24 meshes with a large diameter gear 30 that is rotatably fitted into the small diameter portion of the shaft body 10 via a pipe 28. The pipe 28 is a large diameter gear 30
A pointer 32 is attached to the tip of the pipe 28 . The pointer 32 faces the scale of the scale plate 16. The gears 26, 22, 24, and 30 constitute a speed reduction mechanism. Incidentally, the magnets 18 and 19 may be covered with iron plates.

In the above configuration, the recessed part of the handle 2 of the rotation speed indicator E1 is inserted into a rotating member such as a knob (not shown), and the fixing screw is screwed into the handle 2.
is fixed to the rotating member. Similarly, the rotation speed indicator E
Rotation speed indicators E2 and E3 having the same structure as 1 are attached to adjacent rotating members. In this state, the magnet 19 of the rotation speed indicator E1 and the magnet 18 of the adjacent rotation speed indicator E2 face each other at the shortest distance due to the attractive magnetic force acting between them, and the reference body 14 is oriented in a certain direction. do. When the handle 2 is rotated, the small gear 26 rotates in conjunction with the handle 2. The rotation of the small gear 26 causes the large diameter gear 22 to rotate, and the rotation is transmitted to the pointer 32 via the small gear 24, the large diameter gear 30, and the pipe 28. The amount of rotation of the handle 2 is displayed by the action.

〔effect〕

As mentioned above, in the present invention, the reference body is oriented in a certain direction by magnetic force, and the amount of rotation of the rotating member is measured using this reference body as a reference, so even if the rotating member is vertical, the rotation It is possible to measure the amount of rotation of a member, and is particularly suitable for multiple adjacent arrangements.
