DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover device having a cover for covering an opening.

[0002]

2. Description of the Related Art Conventionally, for example, in a conveyor such as a roller conveyor or a belt conveyor, a conveyor frame is arranged on both sides, and the conveyor frames on both sides are integrally connected by a plurality of crossover members. A plurality of rollers and belt tensioning rollers are arranged side by side between the conveyor frames on both sides.

[0003] The conveyor frame is formed, for example, in a substantially C-shaped cross section having an opening on the outer surface side, and through the opening, a bolt for fixing the conveyor frame and the end of the transit member, or a shaft attached to the conveyor frame. The end of the supported roller is exposed.

In the conveyor, electric wiring such as a power line for supplying electric power to a motor for rotating and driving the rollers or a signal line of a conveyed object detection sensor, air for stopper of the conveyed object and air for accumulation are provided. Piping and the like for the working fluid are wired and piped along the conveyor. These wirings and pipes are generally fixed along the conveyor frame with dedicated stoppers, or housed in a dedicated duct attached to the conveyor frame or legs supporting the conveyor frame. There is also a structure in which wiring and piping are passed through the inside of the conveyor frame, and the opening is closed by a metal metal cover that is fixed to the side surface of the conveyor frame by, for example, screws.

[0005]

However, in the conventional structure, dedicated fasteners and ducts are required for wiring and piping, and since the opening of the conveyor frame is opened, the conveyor frame is opened through the opening. The bolts that fix the end of the conveyor and the ends of the rollers that are supported by the conveyor frame are exposed, and the appearance of the conveyor is impaired.

In a structure in which wiring and piping are passed through the inside of the conveyor frame and closed by a cover, the opening of the conveyor frame is closed to improve the appearance of the conveyor. , And the wiring and piping to be drawn to the outside, it is necessary to provide holes and notches in the conveyor frame and the closing cover, and these need to be processed, there is a problem that the processed part is exposed and the appearance is impaired, At the time of maintenance of the wiring and piping passed inside the conveyor frame, it is necessary to remove the closing cover screwed and fixed to the conveyor frame, which has a problem of poor maintainability.

Embodiments of the present invention will be described below with reference to the drawings.

First, FIGS. 1 to 3 show a first embodiment.

FIG. 3 shows a roller conveyor for linear conveyance as a conveyor. Conveyor frames 1 are arranged on both sides.
Are integrally connected by a plurality of crossover members (not shown), and a plurality of rollers 2 constituting a transport surface are arranged in parallel between the conveyor frames 1 on both sides in a freely rotatable manner. Although not shown, a driving force is transmitted to each of the rollers 2 by a driving mechanism using a motor as a driving source, and each of the rollers 2 is driven to rotate so that a conveyed object placed on these rollers 2 is conveyed. You.

In FIG. 1 and FIG. 2, a conveyor frame 1 has an inner surface portion 3 facing the other conveyor frame 1, and an upper surface portion 4 extending outward from upper and lower edges of the inner surface portion 3.
And upper and lower edge portions 6 on the outer surface side which protrude from the outside of the upper surface portion 4 and the lower surface portion 5 so as to face each other.
7, an opening 8 is provided between the upper and lower edges 6 and 7 along the longitudinal direction of the conveyor frame 1 and has a substantially C-shaped cross section, is formed to be long in the transport direction, and has a space 9 inside. Is formed. The end of the cross-connecting member is bolted to the inner surface 3 and the end of the roller 2 is attached to the inner surface 3.

A cover device (conveyor cover device) that covers the opening 8 is attached to the conveyor frame 1. The cover device 10 includes a fixture 11 and a cover 12.
It has.

The attachments 11 are arranged at intervals at a plurality of positions along the longitudinal direction of the conveyor frame 1.
For example, it is made of metal and has a substantially U-shaped cross section opened upward. One end of the fixture 11 is bent into a substantially U-shape that opens downward, and the lower edge 7 of the conveyor frame 1 is bent.
A frame mounting portion 14 having an engaging groove 13 detachably engaged from above is formed, and a projecting portion 15 is formed outward from the frame mounting portion 14, and the other end of the projecting portion 15 has A cover mounting portion 16 is formed, which is bent into a substantially L-shape and to which the cover 12 is removably mounted. A space 17 is formed between the conveyor frame 1 and the cover 12 by the attachment 11, and a lower surface opening 18 is formed in the lower surface of the space 17 between the plurality of attachments 11.

The cover 12 covers the opening 8 along the longitudinal direction of the conveyor frame 1, and is provided on one edge side of the opening 8 of the conveyor frame 1, that is, on the side of the lower edge 7 via a fixture 11. Mounting part 19 to be attached to
It has a cover part 20 protruding from 19 and a mounting part.
Between the cover 19 and the cover 19, the mounting portion 19 and the cover 20
And a soft layer 21 connecting the mounting section 19 and the cover section.
20 is made of, for example, a hard resin, and the soft layer 21 is integrally formed with a composite structure made of a soft resin, such as soft vinyl chloride, which is softer than the mounting portion 19 and the cover portion 20.

The mounting portion 19 of the cover 12 has a holding structure that is detachably mounted by holding, and is formed in a substantially U-shaped cross section that opens downward, and is attached to the cover mounting portion 16 of the mounting tool 11 from above.

Thus, the problem that the aesthetic appearance is impaired can be solved, and the cover portion 20 can be easily opened and closed even after the cover 12 is attached, so that maintenance can be facilitated.

Since the soft layer 21 which is softer and more flexible than the mounting portion 19 is formed integrally between the mounting portion 19 of the cover 12 and the cover portion 20, the cover portion 20 can be easily attached to the mounting portion 19. The cover 20 can be easily opened and closed.

Since the cover portion 20 of the cover 12 is formed in a convex curved shape on the opposite side to the opening portion 8 from the base end on the mounting portion 19 side to the tip end, elasticity in the closing direction of the opening portion 8 can be obtained. Thus, the state in which the opening 8 is closed can be reliably maintained.

The mounting portion 19 of the cover 12 has a clamping structure that is detachably mounted by clamping.
Can be easily attached to and detached from one edge of the opening 8.

One end is detachably attached to the lower edge 7 of the opening 8 of the conveyor frame 1, the other end is separated from the side of the conveyor frame 1, and the other end is provided with an attaching portion 19 of the cover 12. Removable mounting fixture 11
Are arranged along the longitudinal direction of the conveyor frame 1, so that a plurality of
A lower surface opening 18 opening downward is formed between the lower cover 18 and the cover 12.
Wiring and piping can be easily taken in and out from below.

Conveyor frame 1, cover 12, and fixture 11
The space portion 17 is formed between the space portion 17 and the wiring portion and the piping can be housed in the space portion 17. For example, the power line is housed in the space portion 9 inside the conveyor frame 1, and the space portion outside the conveyor frame 1 is formed. 17 can be stored separately, such as storing signal lines. Further, in this divided storage, the wiring and the piping may be stored separately.
