Description

[Detailed description of the invention] (Industrial application field) This invention consists of making a frame mainly of synthetic resin pipes (including pipes with iron cores), attaching rotating bodies such as rolls or wheels to this, and using a conveyor system. In the field of manufacturing shelving devices, etc., it is particularly concerned with the rotating body support device used as a means of attaching the rotating body to the frame, and more specifically, regarding the rotating body support joint according to the aforementioned Utility Model Application No. 60-34374, as maintenance. This invention relates to a rotating body support device that is improved so that the rotating body can be easily replaced and repaired.

(Prior Art) As one of the effective means for attaching a rotating body such as a roll or a wheel to a synthetic resin pipe frame, a rotating body support joint according to Japanese Utility Model Application No. 60-34374 has been developed. As shown in Fig. 19, it has a substantially C-shaped holding part b that is tightly adhered to the outer diameter surface of the attachment body a such as a pipe, and has a bearing part c on its back part. , a rotating body d is attached to this bearing part c.

However, if a conveyor or conveyor-type shelving device manufactured using this rotating body support joint is used for a long period of time, the rotating body often becomes worn out or damaged, or the shaft becomes bent or damaged. . However, with the structure of the rotating body support joint described above, it is not possible to replace or repair the rotating body etc. as part of maintenance, and in the end, the rotary body is either left in poor condition and used, or even though other parts are healthy. Despite 1
There were inconveniences and uneconomical aspects, such as having to dispose of a piece of equipment and replace it with a new one simply because the condition of a part had deteriorated.

(Purpose of the invention) Therefore, the purpose of this invention is to make it extremely easy to partially replace, repair, or modify only the defective parts of the damaged rotating body or its shaft or bearing in the above-mentioned conveyor, etc. It is therefore an object of the present invention to provide a rotating body support device that has an improved structure that can significantly improve the maintainability and economical efficiency of the conveyor and the like.

(Structure of the invention) As a means to achieve the above object, the rotating body support device of this invention includes: (a) a base member that is attached and fixed to an attached body such as a pipe; It is made up of a support shaft member connected to the shaft member so as to be detachable and replaceable.

(b) The base member includes a fixed part that is tightly attached to the outer diameter surface of the pipe, etc., which is the main body to which it is attached, and is fixed with an adhesive, etc., and an engaging protrusion (or reverse (including the case where the engagement groove is used as an engagement groove (the same applies hereinafter)).

(c) On the other hand, the support shaft member may be an engagement groove (or conversely, an engagement protrusion) for slidably and tightly engaging (coupling) the engagement protrusion.
The same applies hereinafter), and a shaft that rotatably supports the rotating body (or a bearing that supports the shaft of the rotating body; the same applies hereinafter). In other words, by attaching and detaching the support shaft member to and from the base member that is attached and fixed to the main body to which it is attached, such as a pipe, it is possible to easily replace, repair, or modify damaged parts.

(Example) Further details will be explained based on the illustrated example. In Figures 1 to 3, 1 is the main body to be attached, for example, a synthetic resin pipe with an iron core of about φ28 that forms the framework of a wheel conveyor, and 2 is attached and fixed to the outer diameter surface of the pipe 1 in a desired direction. The base member 3 is a support shaft member detachably connected to the base member 2. Base member 2 is AAS resin, support shaft member 3 is PA (nylon 66)
Manufactured as a resin injection molded product. Also,
4 in the figure is a wheel as an example of a rotating body,
This is also considered to be a synthetic resin molded product.

In the base member 2, reference numeral 5 in the figure is a fixed portion 5 which is approximately C-shaped when viewed from the front, has a concave surface having approximately the same diameter as the outer diameter of the pipe 1, and has an equal cross section in the axial direction. This is brought into close contact with the outer diameter surface of the pipe 1. The axial length l of this fixed portion 5 is usually about 23 mm. The base member 2 is attached by pushing its fixing portion 5 into the pipe 1 from the lateral direction, and is fixed by injecting a resin adhesive between the two surfaces. For this reason, about two thin and shallow grooves 6 are formed in the axial direction of the concave surface serving as the fixed portion 5 for injection of the adhesive.

At the center part of the outer diameter side of the fixed part 5 of the base member 2, the thickness of the overlapping part (usually about 2.5 mm) is approximately the same, and the width is set parallel to the axis of the fixed part 5. A flat plate portion 7 of about 30 mm is integrally formed. Approximately parallel both side edges of this flat plate portion 7 are provided as engaging protrusions 8, 8. When the flat plate part 7 is viewed from the front, it is integrally molded with the fixed part 5 in a substantially T-shape.

At the rear end of the engagement protrusion 8, there is a flat plate part 7 and a fixed part 5.
A rib shaped like connecting the outer diameters of the two is provided as a dead end stopper 9. Note that the outer width of the left and right engaging protrusions 8, 8 is such that the width W ₁ on the engagement starting end side is narrow and the width W ₂ on the deep end side is slightly wider (for example, 1 mm).
difference in position) is sloped. That is, when the support shaft member 3 is connected, it is configured so that it can be easily slid and ultimately the two are tightly connected with each other in a state of tight fit due to the wedge effect.

On the other hand, approximately at the center of the flat plate portion 7 on the engagement starting end side, two narrow notches are provided parallel to the engagement direction (same direction as the engagement protrusion 8) with an interval of approximately 6 mm. Groove 1
0 and 10 are provided with a length of about 10 mm, and the part between the grooves is formed into an elastic flexible plate part 11 by cutting the wall thickness from the back side to about 1.5 mm (Fig. 3),
A stopper 12 for preventing slipping off is provided at the tip thereof and protruding upward.

On the other hand, the support shaft member 3 has both side walls 1
The inner dimensions of the shafts 14, 13 are approximately equal to the spacing between the engaging protrusions 8, 8, and the side wall 13 has sufficient height and depth dimensions (usually a=20
mm, b=about 21 mm), and the support shaft member 3 has a hollow box-shaped structure. Projections 15, 15 having a square cross section are provided in the depth direction of the lower ends of the inner surfaces of both side walls 13, 13, and a bottom plate 16 is formed above the projections 15, 15 at intervals approximately equal to the wall thickness (approximately 3 mm) of the flat plate portion 7. Engagement grooves 17, 17 are formed between the engagement grooves 17, which are slidably and closely engaged with the engagement protrusions 8, 8.

Therefore, when the retaining stopper 12 is slightly pushed down to align the engagement grooves 17, 17 of the support shaft member 3 with the engagement protrusions 8, 8 of the base member 2 and slide, the front end surface of the support shaft member 3 and base member 2
It comes to a dead end when the rear end surface of the support shaft member 3 is flush with the rear end surface (Figs. 2 and 3), and at the same time, the retaining stopper 12 is caught on the rear end surface of the support shaft member 3 (Fig. 3), and the two members are integrally connected. A binding relationship is established. In order to facilitate such an operation, an inclined surface 19 that escapes from the retaining stopper 12 is provided on the lower surface of the bottom plate 16 at a substantially central portion on the engagement starting end side.

On the other hand, by pushing down the retaining stopper 12 and moving the support shaft member 3 backward in the opposite direction,
The support shaft member 3 can be easily separated (removed) from the base member 2. Therefore, if the shaft 14 or the wheel 4 is damaged, anyone can easily separate the support shaft member 3 from the base member 2 as described above, whenever necessary, without requiring any skill. It can be replaced or repaired.

In addition, in the support shaft member 3, the shafts 14, 14 are
As a pair of symmetrical pieces arranged on the same center line on the outer surfaces of both side walls 13, 13, and with an outer diameter of φ8,
It is formed as a hollow shaft with a length of about 14.5mm. The wheel 4 is attached by pins 18, 18 (FIG. 1) pushed into the hollow portion 14a.

(Second Embodiment) In the rotating body support device shown in FIGS. 4 and 5, the support shaft member 3 is the same as that of the first embodiment, but the base member 2 is The protrusions 8, 8 are the axis of the base member 2 (therefore, the axis of the pipe 1)
It is characterized by a configuration in which the direction is orthogonal to the .

That is, the flat plate part 7 has two parallel plates protruding in a direction perpendicular to the axis of the base member 2 at approximately the center of the outer diameter side of the fixed part 5 which is approximately C-shaped when viewed from the front direction. It is formed in a shape that is supported by supporting walls 20, 20 to ensure a slightly higher height, that is, a height sufficient to prevent the wheel 4 from coming into contact with the pipe 1.

As in the case of the first embodiment, the engagement groove 17 of the support shaft member 2 is brought into alignment with the engagement protrusions 8, 8 of the base member 2 and the two are slid to form a coupling relationship. However, as a result, the wheels 4, 4 are supported on the support shaft member 3 in such a manner that the rotation center line is in the same direction as the axis of the pipe 1.

(Third, Fourth, Fifth, and Sixth Embodiments) Only the base member 2 is shown in each of FIGS. 6 to 9, but the reason is that the supporting shaft of the first embodiment is This is because the member 3 can be used in common (however, as long as the engagement groove has a common specification, the shape and structure of other parts may be different to some extent), and together they constitute a rotating body support device.

First, the base member 2 shown in FIG. 6 has a fixed portion of approximately C.
An example is shown in which the shape is not limited to the shape of a letter. That is, this fixed part 5' is a cylindrical body through which the pipe passes (however,
It is characterized by being formed as a cylindrical body (including the case of a cylindrical body with one end closed). Other configurations are the same as in the first embodiment.

In the base member 2 shown in FIG. 7, the fixed portion 5' is a cylindrical body, and the engaging protrusions 8, 8 are formed by a support wall 20 protruding in the axial direction of the outer diameter surface of the fixed portion 5'. They are provided as both side edges of the flat plate portion 7 which is supported slightly higher by the support members.

The base member 2 shown in FIG. 8 is an example in which the flat plate portion does not necessarily have to be in a simple flat plate state.
That is, this flat plate part 7' has a shape in which the central part is cut into a circular arc groove shape, and both side edges thereof are provided as engaging protrusions 8, 8. Moreover, the engaging protrusion 8 is characterized in that it is formed into a bilaterally symmetrical acute-angled shape.

The base member 2 in FIG. 9 shows an extreme example in which the so-called flat plate portion described above is apparently almost completely omitted. That is, the left and right engaging protrusions 8, 8 are characterized by a structure in which they are almost completely independent and protrude as having an inverted L-shaped cross section.

It should be noted that the fixing portion 5' of the base member 2 shown in FIGS. 6 to 9 can also be formed into a substantially C-shape when viewed from the front.

(Seventh Embodiment) In the case of the rotating body support device shown in FIGS. 10 to 12, the base member 2 has a fixed portion 5' having a cylindrical shape, and its outer diameter surface is approximately 180° (however, 180° (The engagement ridges 8, 8 are provided as independent ridges in the axial direction at symmetrical positions separated from each other.) Then, an elastic flexible plate part 11 formed by cut grooves 10, 10 is provided on the engagement starting end side, which is approximately the middle part between the engagement protrusions 8, 8 in the same fixed part 5'.
A retaining stopper 12 is provided at the distal end thereof to protrude upward.

On the other hand, the support shaft member 3 has a shape with a width and depth that extends to the upper half of the cylindrical fixed portion 5', and has an angular cross section in the depth direction of the lower end of the inner surface of both side walls 13, 13. Two protrusions 15, 15 are provided in parallel to each other at intervals substantially equal to the height of the engagement protrusions 8, and the intermediate portion thereof is formed as an engagement groove 17. Further, an inclined surface 19 that escapes from the slip-off prevention stopper 12 is provided approximately at the center of the lower surface of the upper surface wall on the engagement starting end side.

Therefore, in the case of this rotating body support device, although the form and structure of the base member 2 and the support shaft member 3 are different from those of the first embodiment, the method of use and operation and effect are almost the same. Incidentally, the fixed portion 5' of the base member 2 may of course be formed into a substantially C-shape.

(Eighth Embodiment) In the case of the rotating body support device shown in FIGS. 13 to 15, the base member 2 is approximately on the outer diameter side of the cylindrical fixed portion 5' as shown in FIG.
Flat plate parts 7, 7 are provided in parallel to the axial direction at symmetrical positions separated by 180 degrees, and both side edges of each are formed as engaging protrusions 8, 8. In addition, an elastic flexible plate portion 11 is provided at the center portion of each of the flat plate portions 7, 7 on the engagement starting end side.
A retaining stopper 12, 12 is provided at the.

On the other hand, the support shaft member 3 has a substantially flat plate shape as shown in FIGS. 14A and 14B, and engagement grooves 17, 17 having a U-shaped cross section are provided on both side edges thereof. Further, one hollow cylindrical shaft 14 is provided protruding from approximately the center of the outer surface.

Therefore, when the two supporting shaft members 3, 3 are used, it is possible to support the two rolls 4', 4', which are rotating bodies, as shown in FIG. When the roll 4' is damaged, by removing only the corresponding support shaft member 3, replacement and repair can be carried out more efficiently and economically. Note that this support shaft member 3 can also be used in combination with the base member 2 shown in FIG. 9.

The engagement groove 17 of the support shaft member 3 can be formed in a V-shaped groove shape as shown in FIG. 16, and can be used, for example, with a common specification with the base member 2 of FIG. 8.

(Others) By the way, for example, in the support shaft member 3 shown in FIG. 14, the shaft 14 is used as a bearing, as shown in FIGS. 17 and 18, by using the shaft 20 fixed to the roll 4' Alternatively, it can be implemented by inserting and supporting the shaft 21 into the hollow portion 14a of the shaft 14. Of course, other embodiments can also be implemented in a similar manner.

(Function and Effect) As described above in detail in conjunction with the embodiments, the rotating body support device of this invention has the following advantages: It is not limited to things with a circular cross section such as pipes.It may also be things such as angle or channel steel.
In that case, the form of the fixing portion of the base member is modified accordingly. ) can be used by attaching and fixing the base member 2 to the base member 2, and can be used without requiring any processing on the main body to which it is attached.

Therefore, when manufacturing wheel conveyors, wheel conveyor-type shelving devices, etc., it is particularly convenient as a means for attaching rotating bodies, and the attached body can utilize its original strength by making use of it, contributing to economical design of the frame. If the wheel 4 or roll 4' or the shaft 14 of the support shaft member 3 is damaged, anyone can simply and easily remove the support shaft member 3 while leaving the base member 2 as is. Can be quickly replaced or repaired.

Therefore, for wheel conveyors, wheel conveyor-type shelving devices, etc. in which this rotating body support device is used, replace only the relevant support shaft member 3 and the attached wheel 4, etc. for the part that has deteriorated. Therefore, it is possible to continue using the device in good condition, and it is possible to eliminate the waste of discarding it when a part becomes unwell. Alternatively, by replacing the support shaft member 3, the wheel 4 or roll 4'
It is also possible to change the direction and position of the rotation axis, and by doing so, it is possible to realize a mode of use that is suitable for the intended use. Thus, a conveyor or the like using the rotating body support device of this invention can significantly improve its maintenance serviceability, economic efficiency, and flexibility in use.
