Description

[Detailed description of the invention] Industrial field of application This invention is used in the field of manufacturing conveyors or conveyor-type shelving devices by constructing a frame using pipes, etc., and attaching rotating bodies such as rolls or wheels to this frame. The invention relates to a rotating body support device used as a means for attaching a rotating body such as a wheel (roller) to a skeleton in a certain manner, and more specifically, the above-mentioned Utility Model Application Publication No. 184123/1984 (November 1988)
This article concerns improvements to the rotating body support device (released on the 17th).

Prior Art A typical example of the rotating body support device described in the above-mentioned Japanese Utility Model Application Publication No. 184123/1988 is shown in FIGS. 10 and 11.

This comprises a base member 2 which is fixedly attached to a main body 1 such as a pipe, and a support shaft member 3 which is connected to the base member 2 so as to be detachable and replaceable. The base member 2 is attached to the main body 1
It has a fixing part 5 fixed to the outer diameter surface of the fixing part 5, and an engagement protrusion 8 for coupling the support shaft member 3 to ride on the top of the fixing part 5. On the other hand, the support shaft member 3 has an engagement groove 1 for coupling to the engagement protrusion 8.
1, and a shaft 14 that rotatably supports a rotary body 4 such as a wheel (or roll) is protruded in a symmetrical arrangement.

Problems to be Solved by the Present Invention In the above-described conventional rotating body support device, the direction in which the support shaft member 3 is attached to and removed from the base member 2 (the engagement direction) is the same as the axial direction of the attached main body 1. If this is used as a component of a conveyor, there is a risk that the support shaft member 3 may come off the base member 2 and fall off as the frequency of sliding of transported articles increases.

Furthermore, since the conventional device has a structure in which the base member 2 is first mounted on the main body 1 to be attached, and the support shaft member 3 is further mounted on top of the base member 2, the rotating body 4 can be moved from the axis line position of the main body 1 to be attached. The mounting position is quite high. In other words, the substantial thickness of the conveyor including the frame formed by the attached main body 1 is large, so there is a lot of wasteful space.

In order to make the support shaft 14 of the support shaft member 3 horizontal, it is important to install the base member 2 horizontally with respect to the main body 1 to which it is attached, but the installation work to achieve the horizontality is technically difficult and time-consuming. This is considered a problem because it takes a lot of time.

Means for Solving the Problems As a means for solving the problems of the prior art described above, a rotating body support device according to the present invention is provided as preferred embodiments are shown in FIGS. 1 to 9 of the drawings. (a) It consists of a base member 2 that is attached and fixed to an attached main body 1 such as a pipe, and a support shaft member 3 that is detachably connected to the base member 2.

(b) The base member 2 has a fixed part 5 that is attached to the outer diameter surface of the main body 1 to which it is attached, and a side part of the fixed part 5 is supported in the vertical direction perpendicular to the axis of the main body 1 to which it is attached. Engagement receiving portion 8 to which the shaft member 3 is coupled
has been established.

(C) The support shaft member 3 has an engagement portion 11 that is engaged and coupled to the engagement receiving portion 8 of the base member 2, and also has a shaft 14 or a bearing that rotatably supports the rotating body 4. The structure is such that it is arranged perpendicular to the axis of the main body 1 to be attached.

Function: The fixing portion 5 of the base member 2 is attached and fixed to the main body 1 to be attached such as a pipe, and then the engaging portion 11 of the support shaft member 3 is engaged with the engaging receiving portion 8 of the base member 2. Rotating body 4 such as a wheel or roll
By attaching it to the shaft 14 (or attaching the rotating body 4 to the support shaft member 3 in advance), the rotating body support device can be assembled and used.

If the support shaft member 3 and the rotating body 4 are damaged, they can be removed from the base member 2 and replaced at any time.

Since the support shaft member 3 is engaged and coupled to the base member 2 in the vertical direction perpendicular to the axis of the main body 1 to which it is attached, it will not come off and fall off regardless of the frequency of sliding of the transported article W. There is no risk of it happening.

In addition, the support shaft member 3 is engaged with and coupled to an engagement receiving portion 8 provided in the vertical direction on the side of the base member 2, so that the support shaft member 3 is arranged side by side with the base member 2. Therefore, the height of the rotating body 4 will not be very high.

By attaching the fixed portion 5 along the rib 20 of the main body 1 to which the base member 2 is attached, the base member 2 can be attached in a proper posture without using a ruler or the like, and for example, it is possible to achieve levelness. It's easy.

Example Next, the illustrated embodiment will be explained.

FIG. 1 shows an exploded view of each component of the rotating body support device according to the invention, and FIGS. 2 to 4 show the assembled state in use.

In the figure, 2 is a base member that is attached and fixed to the outer diameter surface of the pipe 1, which is the main body to be attached.
It is said to be an injection molded product of AAS resin. Further, numeral 3 in the figure is a support shaft member that is detachably connected to the base member 2, and this is made of PA (nylon 66).
It is considered to be a resin injection molded product. In the figure, 4 is a wheel as an example of a rotating body, which is also an injection molded product of synthetic resin.

The pipe 1 is a type of structural material that constructs the framework of, for example, a wheel conveyor shown in FIG. 5 or a roller conveyor shown in FIG. Approximately 1
It is coated with synthetic resin such as AAS with a layer thickness of about mm, and is constructed as a synthetic resin-coated metal pipe with an outer diameter of about φ28. Of course, the pipe 1 may be a solid bar, or may be a square pipe, a shaped steel, etc. with a non-circular cross section.

The base member 2 has a fixed portion 5 formed as a substantially C-shaped concave surface having substantially the same shape and size as the cross-sectional outline of the pipe 1 when viewed in the cross-sectional direction of FIG. The base member 2 is attached by fitting the fixing part 5 laterally into the outer diameter surface of the pipe 1 in a tight state, and bonding (fixing) it by injecting a resin adhesive (or solvent) between the two surfaces. (Figure 3). For this purpose, three thin and shallow injection grooves 6 for injection of adhesive are formed at equal intervals in the axial direction of the concave surface serving as the fixed portion 5.

One side (or both sides are also acceptable) of the outer diameter surface of the fixed portion 5 in the base member 2, specifically, a horizontal line passing through the center of the pipe 1 at the top and bottom when used as a conveyor (FIGS. 5 and 6) A bottomed bag-shaped engagement receiving portion 8 with an open top surface is integrally formed in a vertical direction perpendicular to the axis of the pipe 1 (FIG. 3) at a right angle to the axis of the pipe 1. The shaft member 3 is detachably engaged and coupled. That is, the engagement receiving portion 8 has an engagement groove 7 formed in the vertical direction, and a small rectangular locking hole 9 formed at the center of the bottom thereof. Further, in the front wall of the engagement receiving portion 8, a notch 10 having a width and depth into which the shaft root 13 of the support shaft member 3 is closely fitted is formed at a predetermined depth from the upper edge.

On the other hand, the support shaft member 3 has a vertical plate-shaped engagement portion 11 that closely engages and is coupled to the engagement groove 7 of the engagement receiving portion 8 . Further, a horizontal lid part 12 bent at a substantially right angle is provided at the upper end of the engaging part 11, and is formed into a substantially inverted L-shape when viewed in the cross-sectional direction of FIG.

A retaining protrusion 16 is provided downwardly at the substantially central portion of the lower end of the engaging portion 11, and this protrusion 16 fits into the locking hole 9 of the engagement receiving portion 8 to perform a retaining function. That is, by aligning the engaging portion 11 with the engaging groove 7,
When the shaft root portion 13 is pushed in along the notch portion 10, the retaining protrusion 16 finally fits into the locking hole 9 and becomes completely connected. At this time, the horizontal cover portion 12 of the support shaft member 3 is approximately at the same level as the top of the base member 2.

In addition, if the retainer 16 is removed from the edge of the locking hole 9 and pushed up, the connection is broken, and the support shaft member 3 can be easily removed and replaced or repaired.

The support shaft member 3 has a shaft root portion 13 that is a substantially rectangular convex portion protruding from the front side of the engagement portion 11, and a shaft 1 that rotatably supports the wheel 4 is provided approximately at the center of the front surface thereof.
4 is provided in a direction perpendicular to the axis of the pipe 1. A screw hole 14a is provided in the center of the shaft 14 in the axial direction, and the wheel 4 fitted with the shaft hole 4a is rotatably mounted by being held down by a screw 15 screwed into the screw hole 14a. wheel 4
is sized to protrude above the horizontal cover portion 12 of the support shaft member 3 by a size appropriate for sliding of the transported article W.

FIG. 5 shows a wheel conveyor completed using the rotating body support device configured as described above. In the illustrated example, the wheels 4 are alternately arranged in opposite directions to increase the effective sliding width of the transported article W on the wheels 4. In addition, the conveyor frame has a double pipe structure in which two pipes 1 and 1' are arranged vertically, increasing strength and rigidity. In particular, the upper and lower pipes 1 and 1' are ribbed pipes having concave and convex ribs 20 and 20' that fit into each other in the axial direction, as shown in detail in FIG. 3, to enhance the integration of both pipes. The base member 2 attached to the pipe 1 is designed so that the verticality of the engagement groove 7 of the engagement receiving part 8 can be obtained by bringing the lower edge of the fixed part 5 into contact with the rib 20. Therefore, the ease of mounting the base member 2 and high standards can be ensured, and on the other hand, the wheels 4 can
It has a high load-bearing structure that reliably transfers the load received from other sources to the pipe 1.

Different Embodiments FIGS. 6 and 7 show an embodiment in which a roller 17 is used as the rotating body of the rotating body supporting device.

That is, a bearing hole is provided in the central axial direction of the shaft 14 of the support shaft member 3 in place of the above-described screw hole 14a, and on the other hand, the shaft 1 is provided at both ends of the roller 17.
A roller conveyor is constructed by fixing and protruding the shaft 17a and fitting the shaft 17a into the bearing hole and rotatably supporting the shaft 17a.

Second Embodiment The rotating body support device shown in FIGS. 8 and 9 has an engagement protrusion 7' symmetrically provided as the engagement receiving portion 8 of the base member 2, and A groove-shaped engaging portion 11' into which the engaging protrusion 7' is closely fitted is provided on one side. Further, a locking hole 9' is provided in the cover part 12 of the support shaft member 3, and a locking hole 9' is provided in the cover part 12 of the support shaft member 3.
A notch 2 is provided at approximately the center of the engagement receiving portion 8 in
1, a retaining protrusion 16' is provided upward, and the base member 2 and the support shaft member 3 are completely connected and fixed by fitting together.

Effects of the present invention As explained above in conjunction with the embodiments, the rotating body support device of this invention is capable of attaching the roller 17 or wheel 4 as a rotating body to the base member 2 on the attached main body 1 such as a pipe. It can be used easily and reliably by attaching and fixing it.

Moreover, since no processing is required on the attached body 1, not only can man-hours be saved and work efficiency is improved when manufacturing wheel conveyors and wheel conveyor-type shelving devices, etc., but the attached body 1 is It contributes to the economical design of the frame because it can be used to increase strength.

In addition, if the wheel 4, roller 17, or shaft 14 of the support shaft member 3 is damaged, the base member 2 can be left as is and only the support shaft member 3 can be replaced, allowing easy and quick repair whenever necessary. It can be economical.

Moreover, since the support shaft member 3 is engaged with and coupled to the base member 2 in a direction perpendicular to the axis of the main body 1 to which it is attached, the amount of sliding frequency of the transported article W, sliding resistance, or sliding resistance can be reduced. Regardless of the magnitude of the impact, there is no fear that the support shaft member 3 will come off and separate or move unstablely, contributing to the provision of a conveyor or the like with high structural stability.

In addition, the shaft 14 supporting the rotating body 4 is located on the side of the attached main body 1, and the position of the rotating body 4 is not very high, so the conveyor can be configured to be thin (conventional example shown in FIGS. 10 and 11). In this case, the thickness is approximately twice the outer diameter of the main body 1 to be attached, but the thickness of this invention is
(approximately 1.2 to 1.3 times), contributing to the provision of a conveyor with less detox base.
