DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a conveyor device.

[0002]

2. Description of the Related Art Conventionally, when a conveyor device is constructed by arranging at least two independently driven conveyors in the front-rear direction, a conveyor having at least four support legs and capable of being independently installed on a floor surface is simply used. They were arranged in the front-back direction.

[0003]

Disadvantages of the prior art The conventional conveyor apparatus has the following disadvantages. Since at least four support legs are provided for each conveyor, there is a disadvantage that the number of support legs becomes unnecessarily large.

[0004]

The present invention employs the following means to solve the above-mentioned drawbacks. The invention of claim 1 includes a support frame having required support legs and at least two conveyors having no support legs attached to the support frame. The left and right side plates of the support frame are formed of L-shaped side plates having a horizontal portion and a vertical portion, and the left and right side plates of the conveyor have a flat portion mounted on an upper end of the vertical portion, and a flat portion. An upper connecting portion that contacts the vertical portion connected to the vertical portion, a hanging portion that is connected to the flat portion and faces the vertical portion at a predetermined interval, and a hanging portion that is connected to the lower end of the hanging portion and contacts the horizontal portion. 2. The device according to claim 1, further comprising a lower connecting portion which is in contact with the lower connecting portion. The invention of claim 3 is
A driving source shaft for a conveyor drive is provided for each conveyor, a meshing clutch device is provided for each driving source shaft, and a driving force of a clutch device having an engaging portion rotatably fitted to the driving source shaft. The member is rotated by one motor, and the driven member of the clutch device having an engaging portion facing the engaging portion of the driving member does not rotate relative to the driving source shaft but slides in the axial direction. 3. The device according to claim 1, which is movably provided.

[0005]

According to the present invention, the following effects can be obtained by the above configuration. According to the first aspect of the present invention, since at least two conveyors having no support legs are attached to the support frame having the required number of support legs, at least four support legs are provided for each conveyor. The number of supporting legs can be reduced as compared with the case. Further, since the conveyor is attached to the support frame, the support frame exerts a function such as a positioning jig, and it is easy to install the conveyor in a straight line. According to the invention of claim 2, the flat portion of the side plate of the conveyor is placed on the vertical portion of the side plate of the support frame, and the lower connecting portion of the side plate of the conveyor is placed on the horizontal portion of the side plate of the support frame to support the upper connecting portion. The conveyor can be easily attached to the support frame because it is sufficient that the conveyor is fixed to the vertical portion of the side plate of the frame and the lower connecting portion is fixed to the horizontal portion of the side plate of the support frame. According to the invention of claim 3, since the number of motors can be reduced, the conveyor device can be manufactured at low cost.
