Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side cover for closing an open portion of a conveyor frame.

[0002]

2. Description of the Related Art As a side cover of a conveyor frame of this type, there is, for example, one disclosed in Japanese Patent Application No. 60-93539, entitled "Microfilm".

This side cover, as shown in FIG.
A flat plate-shaped member formed by forming a ridge 101 along the longitudinal direction of the cover 100, and elastically sandwiching a support body 104 bolted in a recess 103 of a conveyor frame 102 as shown in FIGS. 6 and 7. The ridges 101 are attached in such a manner that they are held by the pieces 105, 105.

Therefore, when the above-mentioned form is adopted, the side cover can be easily attached to and detached from the conveyor frame.

However, when it becomes necessary to attach a device such as a guide or an optical sensor held by the support member to the side cover, a screw hole is formed in the side cover at each position where the support member is attached. It requires work and is troublesome. Further, the work becomes more troublesome when the mounting position of the device or the like requires accuracy.

Therefore, in the industry where this type of conveyor is used, devices such as guides and optical sensors can be easily attached, and even in the case of attachment requiring positional accuracy, the conveyor does not require difficult work. The development of frame side covers is desired.

[0007]

In view of the above, according to the present invention, a device such as a guide or an optical sensor can be easily mounted, and even if the mounting requires positional accuracy, it does not require a difficult operation. The task is to provide a side cover for the frame.

[0008]

According to the present invention, in a side cover of a conveyor frame to which a supporting member for holding devices such as guides and sensors is screwed, a dovetail groove along the longitudinal direction of the conveyor frame is provided on the cover surface side. A female screw body is formed in the dovetail groove while being formed and slides along the groove locus, and the female screw body serves as a screw fixing portion of the support member.

It is preferable that a plurality of dovetail grooves are provided and set parallel to each other.

When the side cover of the present invention is adopted,
A support member that holds a device such as a guide or a sensor may be screwed to the female screw body through the opening of the dovetail groove, and thus the guide or the like can be easily attached.

Since the female screw body is provided so as to slide along the groove locus of the dovetail groove, it is possible to adjust the position of the supporting member by a small amount. Therefore, the proper position of the device such as the guide or the sensor can be adjusted. Can be easily attached to.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows one end of a conveyor having a side cover SC which is an embodiment of the present invention. A conveyor belt 7 is provided on a pulley 8 rotatably installed between a pair of conveyor frames 9. Shows the state of being stretched. In FIG. 1, reference numeral 6 is a support member and reference numeral 5 is a guide.

The structure of the side cover SC and the members directly related thereto will be described below. [Conveyor frame 9] Conveyor frame 9
As shown in FIG. 1 and FIG. 2, each of the vertical bars 90 is formed of a cross-section U-shaped section steel (generally referred to as a channel member) having horizontal pieces 91, 91 provided on the upper and lower portions thereof. Vertical piece 9
Reference numeral 0 indicates a through hole 9 used for connection with the side cover SC.
2 is formed. [About Guide 5] As shown in FIGS. 2 and 3, the guide 5 includes a pipe 50 and a male screw rod 51 welded to the pipe 50.
And two nuts 52 screwed into the male screw rod 51. [Regarding Support Member 6] As shown in FIGS. 1 and 2, the support member 6 includes through holes 60, 6 formed in the upper, middle, and lower portions.
It is configured by a so-called flat bar having 1, 62.

As shown in FIG. 3, the guide 5 is attached so that the male screw rod 51 is inserted into the through hole 60 and is sandwiched by the nuts 52 and 52. Further, the through holes 61 and 62 are formed at positions corresponding to the dovetail groove 1 described later, as shown in FIG. [Regarding Side Cover SC] The side cover SC is formed by extruding an aluminum alloy, and as shown in FIG. 1, a dovetail groove 1 that is parallel to the longitudinal direction of the conveyor frame 9 in the mounted state on the surface side thereof. , 1 are formed, and a groove 2 is formed in the middle portion between the dovetail grooves 1, 1. Further, as shown in FIG. 2, on the back surface side of the side cover SC, a contact piece 4 that abuts on the inner surface of the vertical piece 90 is provided in the middle thereof.

As shown in FIGS. 2 and 3, the dovetail groove 1 comprises a narrow portion 10 and a large portion 11, and the large portion 1
1, a nut N (corresponding to the female screw body described in the column of means for solving the problem) is inserted. The nut N described above can freely slide along the substantial portion 11 shown in FIGS. 3 and 4.

As shown in FIGS. 2 and 4, the groove 2 has a through hole 20 formed at a predetermined position on the bottom surface thereof for use in coupling with the conveyor frame 9.

In this groove 2, as shown in FIG. 2, the side cover SC by the bolt B1 is formed by the conveyor frame 9
, The bolt B1 is attached to the side cover S.
The depth is set so as not to project from the surface of C. Thereby, when the support member 6 is moved laterally, the bolt B
The head of 1 does not interfere with this movement. [Work to attach the guide 5 to the side cover SC ...
One Mode] First, as shown in FIG. 2, the side cover SC is
The through holes 20 and 92 are used for screwing with bolts or the like.

Next, as shown in FIGS. 2 and 3, the through hole 6
Bolt B through nuts 1, 62 and washers W
Then, the guide 5 is attached to the side cover SC.
The support member 6 is moved to a proper position, and when the positioning is completed, the bolt B is screwed into the nut N to be fully tightened. The work is now completed.

FIG. 5 shows a state in which the optical sensor S (not limited to this, other devices) may be attached to the side cover SC instead of the guide 5. In this case, position accuracy is required for mounting the optical sensor S, but when this side cover SC is used, fine position adjustment enables high-level position adjustment.

Although the above-mentioned conveyor is of the belt type, the side cover SC can be applied to a so-called roller type conveyor and other types of conveyors.

[0022]

Since the present invention has the above-mentioned structure, it has the following effects.

From the contents described in the column of means for solving the problems, when the side cover of the conveyor frame of the present invention is adopted, devices such as guides and optical sensors can be easily attached, and further, the positional accuracy can be improved. However, even in the case of a required installation, a difficult work is not required.
