Description

[Detailed description of the invention] [Summary] The display body presser of the flow indicator is formed from a film.

[Industrial application field]

The present invention relates to a flow indicator, and more specifically, to a flow indicator in which a plastic film is used as a display holder instead of a conventional glass plate.

[Conventional technology]

The flow indicator shown in a plan view in FIG. 2 is a known one, and in the same figure, 11 is a conveyance belt that rotates clockwise as seen in the figure, and 12 is a display body (also called a rotating body). , 13 is a display body holder made of a glass plate, and 14 is an R part holder made of, for example, a stainless steel plate. In this display, the display surface 15 is the surface on which the display presser 13 is located.

As shown in the perspective view of FIG. 3, the display 12 has a rectangular parallelepiped shape and is rotatably attached to the shaft 16. For example, one display 12a is white and the back side 12b is black. In display, either the display surface 12a or the back surface 12b is exposed to the outside (front) of the display surface 15, and characters, symbols, etc. are displayed in a white and black arrangement. Shaft 16
A plurality of display bodies are arranged vertically at intervals, and the shaft 16 is connected to a mounting bracket 17, and is fixed to the conveyor belt 11 by the mounting bracket 17, so that one-way movement of the conveyor belt 11 is prevented. At the same time, the shaft 16 and therefore the display body 12 also move. Display body 16
A magnetic piece 18 is embedded in one side of.

In operation, the display objects 12 passing through the R section of the display surface are attracted by the magnetic pieces 18 to the permanent magnet placed in the erasing head 19, so that all the display objects are lined up in the same direction and erased. Next, an electromagnet placed in the write head 20 selectively writes the magnetic piece 1.
Writing is performed by attracting 8 and changing the direction of only the specific display body, and then the display body turns to the display surface 15 to display a specific display (characters, symbols, etc.).

[Problem that the invention attempts to solve]

During display, the conveyor belt 11 undergoes considerable vibration, which may change the orientation of the display 12 and cause the display to not be accurate or clean. Therefore, a display body presser 13 made of a glass plate is placed on the display surface 15 to bring the glass plate and the surface of the display body into contact to prevent the display body from changing its orientation.

However, it is difficult to arrange the glass plate in contact with all the display bodies, and if the glass plate is misaligned, this will result in malfunction of the display body. In particular, if the connecting portions of the glass plate and the stainless steel plate do not match, the glass plate will not come into proper contact with the display body, resulting in erroneous display.

The present invention was created in view of these points, and an object of the present invention is to provide a display body holder that can prevent erroneous display of the display body of a flow indicator.

[Means for solving problems]

FIG. 1 is a plan view of an embodiment of the present invention, in which numeral 21 is a plastic film display body holder according to the present invention, and other parts are the same as in the conventional example.

In the present invention, a display body presser 21 made of plastic film is placed so as to surround the display body 12 while being in contact with the display body 12.

[Effect]

In the present invention, the plastic film is used to wrap and press the display body 12, and also serves as a presser for the R portion, so that the display body is closely attached to the display body and the display effect is improved without requiring adjustment as in the conventional example.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In this invention, the shaft 1 shown in FIG.
A plastic film having a width approximately equal to the length of the display body 6 is prepared and used as a display body presser 21.
To do this, one end of the plastic film is fixed to the support rod 22, the plastic film is spread along the display 12, and then fixed to the other support rod 22. The surface of the plastic film that comes into contact with the display body 12 may be coated with glass to prevent wear.

As mentioned above, the plastic film is used as display body 1.
2, unnecessary rotation of the display body 12 is completely prevented. Also,
Since the R section presser 14 also contacts the display 12 and forms the R section presser, there is no need for a stainless steel R section presser as in the conventional example, and a single plastic film is used to hold the display surface 15 and the R section presser. It becomes the display body presser of 14.

As described above, the plastic film only needs to be fixed at one end to one of the support rods 22 and stretched along the display body 12, and no adjustment process is required, so it can be easily installed or replaced. . Traditionally, glass plates were adjusted during assembly and maintenance.
This solves the problem of having to check whether or not there is proper contact with the display.

In the conventional case, the glass plate cost several thousand yen, and in addition, it was necessary to prepare a stainless steel plate to hold the R part display body, but according to the present invention, the plastic plate cost less than 1,000 yen. The display body holder can be made from film, which is advantageous in terms of cost.

[Effect of idea]

As described above, according to the present invention, by making the display body holder using plastic film, accurate and clear display is possible, and installation, replacement, and maintenance are easy, and costs are reduced. .
