Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a display device for a platform scale that displays the weight of an object to be weighed measured by a platform scale.

``Prior Art'' Conventionally, display devices for platform scales have been either body-mounted type that is attached to the top of a support vertically installed on the platform scale body, or floor scale display devices that are attached to the top of a stand placed on the floor near the platform scale. There were stand-alone models, wall-mounted models that could be hung on the wall, and table-top models that could be placed on a tabletop, and each of these models was manufactured individually. Therefore, each part used is different, making inventory control and maintenance of the parts troublesome, and high-mix low-volume production results in high costs.

In order to solve these problems, the present applicant first developed a weighing scale display (Utility Application No. 58-28579) that can be used in any of the above-mentioned floor-standing, wall-mounted, and table-top types.
No.) was proposed.

``Problems to be solved by the invention'' However, in the above-mentioned scale display, when the column with the display device attached is installed vertically on the platform scale body, a part is required to attach the column to the platform scale body. In addition, if the display device is a floor-standing type and is placed near the scale body, a separate stand must be prepared to support the column to which the display device is attached, and it is also necessary to prepare a stand to support the column on which the display device is attached. In such cases, the object to be weighed and the support may come into contact with each other, making it impossible to accurately detect the weight, or when weighing a long object, the support may get in the way, making it difficult to lift and lower the object onto the weighing pan. However, it has not been possible to completely resolve the problems encountered.

In view of the above-mentioned circumstances, the present invention can not only be used separately from the scale body if necessary, but also can be attached to the scale body, is inexpensive, easy to use, and has parts in stock. The object of the present invention is to provide a display device for a platform scale that is extremely easy to manage and maintain.

"Means for solving the problem" The present invention uses a hollow member in the fixed frame that constitutes the support mechanism that supports the load detection part of the platform scale.
A leg part that is removably inserted into the hollow member, a fixing member that fixes the leg part to the hollow member, a column that is maintained in an upright state by the leg part, and a column that is attached to the top of the column. , and a display section that displays the weight detected by the load detection section.

The display unit can be used as a floor-standing type because the support is kept upright by the legs, and can also be used as a body-mounted type by attaching the legs to the hollow member using fixing members. can do.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a perspective view showing the structure of an embodiment of the present invention. In this figure, 1 is the platform scale body;
The platform scale body 1 consists of a pair of fixed frames 2a and 2b formed by bending a pipe material having a square cross section into a U shape.
, a connecting member 4 that interconnects these fixed frames 2a, 2b, support legs 6, etc., which are arranged above the fixed frames 2a, 2b, and are made of pipe material in a U-shape like the fixed frames 2a, 2b. A pair of movable frames 8a and 8b bent into a shape, a connecting member 10 that interconnects these movable frames 8a and 8b, and a load cell 12 that is provided between the connecting members 4 and 10 and constitutes a load detection section. , and a weighing pan 14 placed on movable frames 8a and 8b. On the other hand, 16a and 16b are a pair of legs made of pipe material that can be inserted into and removed from the fixed frames 2a and 2b. Wing bolts 18 and 16b are inserted into elongated holes 2c formed in the fixed frames 2a and 2b, respectively. Fixed frame 2a, 2 by 18
b (see Figure 2). Leg portion 16a,
16b are mutually connected by a connecting pipe 16c, and in the center of the connecting pipe 16c is a lower pipe material 20a, an upper pipe material 20b slidably inserted into the lower pipe material 20a, A column 20 consisting of a butterfly bolt 20c for fixing an upper pipe material 20b to a lower pipe material 20a is vertically fixed. A display section 22 for displaying the weight detected by the load cell 12 is detachably attached to the upper end of the upper pipe material 20b of the support column 20. In this case, the lower surface of the display section 22 has an insertion hole 22a into which the upper end of the upper pipe 20a is inserted.
A butterfly bolt 22b for fixing the upper pipe 20a inserted into the insertion hole 22a is attached to the rear surface, and locking holes 22c for hanging the display section 22 on a wall surface etc. are formed. has been done.

In the above configuration, by using the display unit 22 alone, it can be used as a wall-mounted type or a tabletop type, and by attaching the display unit 22 to the upper end of the upper pipe material 20b of the support column 20, it can be used as a floor-standing type. Furthermore, by inserting the legs 16a, 16b into the fixed frames 2a, 2b and fixing them with wing bolts 18, it can be used as a body-mounted type. In this case, by loosening the butterfly bolt 18, the display section 22
horizontally, and by loosening the butterfly bolt 20c, the display section 22 is moved vertically,
Further, by loosening the butterfly bolt 22b, the display section 22 can be horizontally rotated, thereby making it possible to freely adjust the position of the display section 22.

Next, other embodiments of the present invention will be described. FIG. 3 shows an embodiment in which the display section 22 is configured to be vertically swingable by loosening the butterfly bolts 25, and FIG. 4 shows an embodiment in which the support column 20 is configured from a single pipe material. An example is shown in FIG.
B shows an embodiment in which the legs 16a, 16b and the support 20 are made of a single pipe material, and the display part 22 is configured to be vertically swingable by loosening the butterfly bolts 27. . In addition, in FIG. 6, the leg portion 16a is formed by a pair of substantially L-shaped pipe members.
This shows an embodiment in which the support column 20, the leg portion 16b, and the support column 20 are respectively configured, and the display section 22 is fixed to the upper end of the pair of support columns 20 using butterfly bolts 29. As shown in Figures A to C, a pair of insertion holes 30a, 30b, and 31 are inserted into the lower surface of the display section 22 into which the upper end of each support column 20 is inserted, respectively.
By providing a and 31b, it becomes possible to fix the display section 22 at a position horizontally rotated by 90 degrees from the state shown in the figure.

Note that the fixing method for fixing the legs 16a, 16b to the hollow member is not limited to the above-mentioned method.
It doesn't matter how you press down 6b, the key is to press down on leg 1.
Any method may be used as long as it securely fixes 6a and 16b. Furthermore, the leg portion 16a,
The material 16b is not limited to pipe material, but may also be solid material or shaped steel.

"Effects of the Invention" As explained above, according to the present invention, a hollow member is used for the fixed frame constituting the support mechanism that supports the load detection part of the platform scale, and the legs are removably inserted into the hollow member. a fixing member that fixes the leg to the hollow member; a support that is maintained in an upright state by the leg; and a support that is attached to the top of the support and that is detected by the load detection unit. Since it is equipped with a display section that displays the weight, it can of course be used separately from the scale body if necessary, but it can also be used with the scale attached to the body, and in either case, new parts are required. It can be used without the need for. Therefore, when the support is in the way when weighing something larger than the weighing pan, it can be removed from the scale body, making it inexpensive, easy to use, and extremely easy to manage inventory of parts and maintain. Obtainable.
