Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a conveyor frame, and particularly facilitates the removal of a return conveyor.

[Conventional technology]

Examples of conventional conveyor frames include those shown in FIGS. 3 and 4. Figure 3 is a perspective view of the overall structure of the roller chain conveyor with a part of the conveyor frame CF cut away;
The figure is a cross-sectional structural diagram of the conveyor frame CF. In the figure, 1 is an endless conveyor chain equipped with freely rotating rollers 2;
is the sprocket that drives this conveyor chain. The conveyor frame CF in which the conveyor chain 1 is housed is integrally molded by extrusion of aluminum material into two sections, upper and lower, and is supported on pillars 4 as a pair of left and right sections at a predetermined distance. Reference numeral 5 denotes an upper feeding conveyor chamber that accommodates the feeding side 1a of the conveyor chain 1, and has an open structure with an opening 6 facing inward. Reference numeral 7 denotes a lower return conveyor chamber that accommodates the return side 1b of the conveyor chain 1, and has a sealed structure surrounding the top, bottom, left and right sides of the conveyor.

Both ends of the conveyed object W are inserted into the feeding conveyor chamber 5 through openings 6 of a pair of opposing conveyor frames CF, and placed on the rollers 2.
Then, it is conveyed by a conveyor chain 1 that is fed through a sprocket 3 that is rotationally driven by a drive motor (not shown). Moreover, if you use external force,
Independently from conveyor chain 1 as necessary,
It is also possible to freely move back and forth on the roller 2 and to stop it.

[Problem that the invention attempts to solve]

However, in such a conventional conveyor frame, the conveyor frame CF is
Since the stage was an integral structure and the return conveyor chamber 7 had a sealed structure, the return conveyor chain 1b
The problem was that it was difficult to connect the conveyor to extend it as needed, or to shorten it by cutting it apart.

This idea was made by focusing on these conventional problems, and is a conveyor in which the outside wall of the conveyor chamber is formed to be openable, and one side of the chain rail for guiding the conveyor chain is provided inside the side wall. The aim is to solve the above problems by providing a frame.

[Means for solving problems]

This invention, which achieves the above object, has an endless conveyor chain that is stretched between sprockets arranged at specific intervals, and has a feeding conveyor chamber that houses the sending side of the conveyor chain, and a feeding conveyor chamber that houses the return side of the conveyor chain. In a conveyor frame integrally formed with vertically divided return conveyor chambers, an outer wall of at least the return conveyor chamber of both the conveyor chambers is formed separately from the conveyor frame main body, and the outer wall The chain rail that guides the conveyor chain is divided into parts, and one part is provided inside the outer wall and the other part is provided inside the main frame. This is a conveyor frame featuring:

[Effect]

With the above configuration, if necessary, by removing and separating the subframe from the main frame, the return frame chamber opens outward, so that the return conveyor chain can be extended, shortened, replaced, etc.
Repair work etc. can be done easily.

By dividing the chain rail that guides the conveyor chain and installing one inside the outer wall and the other inside the main frame, work can be carried out without interfering in the conveyor room without lifting the conveyor chain.

〔Example〕 This invention will be explained below based on the drawings.

FIG. 1 is a diagram showing an embodiment of this invention.

In addition, the same reference numerals are attached to the same or equivalent parts as in the conventional art.

First, to explain the configuration, CF1 is a main frame as a conveyor frame body, which is an extrusion molded product of aluminum, and forms the inner side wall of the conveyor frame CF. CF2 is a sub-frame extruded separately from the inner side wall CF1, and in this embodiment, the entire outer wall of the conveyor frame CF covers both the upper and lower chambers of the feed conveyor chamber 5 and the return conveyor chamber 7. or constitute a part of it. Reference numeral 10 denotes a tightening bolt that uses a T-slot 11 to fasten the base of the main frame CF1 and the lower part of the sub-frame CF2. Reference numeral 12 denotes a frame stay made of, for example, a hexagonal metal material, which is interposed between the main frame CF1 and the subframe CF2, and is connected to both frames CF by a fastening bolt 13.
1. CF2 is fixed. Tightening bolt 10 and
Connect the outer wall to the main frame CF with the bolt 10.
1, when the outer wall is tightened, the outer wall comes into contact with the main frame CF1, and the outer wall is fixed by a positioning section consisting of a vertical contact surface 17 and a mounting direction contact surface 18, which determine the position in the vertical direction and the installation direction, respectively. It is configured so that it can be positioned in the vertical direction and in the mounting direction with respect to the conveyor frame body CF, and even when the chain is reinstalled, the vertical height and mounting direction of the chain rails 14 on both sides can be surely matched. Reference numeral 14 is a chain rail made of, for example, ultra-high density polyethylene, and rollers 2 are rotatably mounted in the middle of the free flow chain 1.
is adapted to roll on the rail 14. Reference numeral 15 denotes a side guide that prevents the transported object W from shifting laterally, and is bolted to the upper end of the subframe CF2. 16 is a plastic cover that is fitted into the main frame CF1.

Next, the effect will be explained.

If necessary, loosen and remove the tightening bolts 10 on the outside wall, and attach the subframe CF2 to the main frame CF.
Easily remove and separate from 1. As a result, the return conveyor chamber 7 opens outward, and
Since one of the chain rails 14 provided on the outer wall is removed, work such as extending, shortening, replacing, or repairing the return conveyor chain 1b can be done extremely easily from outside the conveyor frame without having to lift the chain 1. It can be carried out. Note that if the side wall is removed, the chain can be easily removed and removed, and the height of the ceilings of the conveyor rooms 5 and 7 can be increased, and if the sub-frame CF2 is removed, the support of the rollers 2 by the chain rail 14 can be increased. Although it is only on one side, both ends of chain 1 are hung over sprocket 3, so the entire chain will not come off, and it will not be necessary to lift chain 1 while it is still within the chain rail 14. The work can be carried out even if Of course, the conveyor chambers 5 and 7 can also be cleaned easily.

In addition, even when repeatedly attaching and detaching, we have provided a positioning part that positions the outer wall with respect to the conveyor frame main body CF in the vertical direction and the installation direction.
Even when remounting, the vertical heights and mounting directions of the chain rails 14 on both sides can be reliably matched, improving maintainability.

Note that since the chain rail 14 is made of synthetic resin, the running noise of the chain roller 2 can be significantly reduced. Also, plastic cover 1
6, it is possible to improve safety and prevent falling objects from getting caught in the chain.

FIG. 2 shows another embodiment.

This embodiment differs from the first embodiment in that the subframe CF2 is used only as an outer wall of the return conveyor chamber 7. There are advantages such as the fact that the subframe CF2 can be more easily attached and detached when performing work on the return conveyor chain 1b.

[Effect of idea]

As explained above, according to this idea,
The outer wall of the conveyor frame can be separated from the frame body and opened, and since one chain rail is provided on the outer wall, the conveyor chain can be extended without removing it from the frame.
Work such as shortening can be easily carried out, and since the conveyor chain can be installed and removed without lifting it, the chain can be replaced without interfering with the conveyor room, which has the effect of lowering the height of the conveyor room. can get.
