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 opening of a conveyor frame.

[0002]

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

[0003] As shown in FIG.
It is a flat plate formed by forming ridges 101 along the longitudinal direction of the cover 100. As shown in FIGS. 6 and 7, the support 104 is bolted in the recess 103 of the conveyor frame 102 and elastically clamps the support 104. The pieces 105 are attached in such a manner that the ridge 101 is held between the pieces 105 and 105.

Therefore, when the above-mentioned type is adopted, the attachment and detachment of the side cover to the conveyor frame becomes easy.

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, in the above-described apparatus, a screw hole is formed in the side cover at each position where the support member is attached. It requires work and is troublesome. And, when accuracy is required for the mounting position of the device or the like, the work becomes more troublesome.

[0006] Therefore, in the industry using this type of conveyor, equipment such as guides and optical sensors can be easily attached, and further, even in the case of attachment requiring positional accuracy, a conveyor that does not require difficult work is required. The development of a frame side cover is desired.

[0007]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a conveyor such as a guide and an optical sensor can be easily attached, and even if the installation requires a high positional accuracy, a difficult operation is not required. It is an object to provide a frame side cover.

[0008]

SUMMARY OF THE INVENTION This invention provides a support member for holding the device, such as guides and sensors in the side cover of the conveyor frame to be screwed cover backside
A contact piece that abuts against the inner surface of the conveyor frame,
Grooves along the length of the conveyor frame on the cover surface
Formed and formed in this groove and conveyor frame respectively
Screwed side cover using bolts
Further, a dovetail groove is formed on the cover surface side along the longitudinal direction of the conveyor frame, and a female screw body is provided in the dovetail groove so as to slide along a groove locus. The screw body serves as a screwing portion of the support member.

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

When the side cover of the present invention is adopted,
A support member for holding a device such as a guide or a sensor may be screwed to the female screw body through the open portion of the dovetail groove, so that 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, the minute position of the support member can be adjusted. Can be easily attached to

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 according to an embodiment of the present invention. A conveyor belt 7 is mounted on a pulley 8 rotatably mounted between a pair of conveyor frames 9. Is shown in a stretched state. In FIG. 1, reference numeral 6 denotes a support member, and reference numeral 5 denotes a guide.

The structure of the side cover SC and members directly related thereto will be described below. [About Conveyor Frame 9] Conveyor Frame 9
As shown in FIG. 1 and FIG. 2, the cross section is formed of a U-shaped section steel (generally referred to as a channel material) in which horizontal pieces 91, 91 are provided at upper and lower portions of a vertical piece 90. Vertical piece 9
0 is a through hole 9 used for coupling with the side cover SC.
2 are formed. [About Guide 5] As shown in FIGS. 2 and 3, the guide 5 is composed of a pipe 50 and a male screw rod 51 welded thereto.
And two nuts 52 screwed into the male screw rod 51. [Supporting member 6] As shown in FIGS. 1 and 2, the supporting member 6 has through holes 60, 6 formed in upper, middle and lower portions.
It is constituted by a so-called flat bar having 1,62.

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

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

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 connection with the conveyor frame 9.

As shown in FIG. 2, the side cover SC by the bolt B1 is
When the bolt B1 is connected to the side cover S
The depth is set so as not to protrude from the surface of C. Thus, when the support member 6 is moved in the lateral direction, the bolt B
The head of one does not disturb this movement. [Work to attach the guide 5 to the side cover SC ...
One Embodiment] First, as shown in FIG.
Using the through holes 20 and 92, screws are used to fix the screws.

Next, as shown in FIG. 2 and FIG.
1 and 62 and washer W to bolt N
And the guide 5 is attached to the side cover SC.
The support member 6 is moved to an appropriate position, and when the positioning is completed, the bolt B is screwed into the nut N to perform the final tightening. The work is now completed.

FIG. 5 shows a state in which the optical sensor S (not limited to this, but may be another device) is attached to the side cover SC instead of the guide 5. In this case, the mounting of the optical sensor S requires positional accuracy, but when the side cover SC is used, fine positional adjustment is possible by fine adjustment.

Here, the above-mentioned conveyor is of a belt type, but this side cover SC can also be used for a so-called roller type conveyor and other types of conveyors.

[0022]

Since the present invention has the above configuration, the following effects are obtained.

From the contents described in the section of the means for solving the problems, when the side cover of the conveyor frame of the present invention is employed, devices such as guides and optical sensors can be easily attached, and furthermore, the positional accuracy can be improved. Even in the case of the installation requiring the above, a difficult operation is not required.
