Description

[Detailed description of the invention] This invention relates to a belt-type trolley conveyor in which a belt with beads formed on the side edges is applied to the trolley conveyor, and its purpose is to reduce the noise generated from the conveyor. To prevent this, to enable the conveyor to run horizontally, vertically, and in a stable manner without scattering oil, and to simplify the construction of the conveyor device.

In conventional trolley conveyor devices, rollers are attached to the chain so that the rollers run along guide rails, and a hook or the like is attached to the chain so that the conveyed object is suspended.

However, since the chenos and guide rails are made of metal parts, not only do the chenos come in contact with the guide rails, which causes a lot of noise, but also when the conveyor is curved, the effective radius required for the curve is 300 mm. 50
It needed to be as large as 0 mm, which was disadvantageous for movement with many curves.

Furthermore, since the conveyor device is mostly composed of metal parts, the weight of the device itself increases, which poses great difficulties during construction.

Therefore, this invention eliminates the drawbacks of these conventional trolley conveyor devices.

Conveyor belts are known in which a bead is formed on the side edge of the belt, and the belt is held and guided by rollers arranged in parallel from both sides of the bead, and it is also used as a bending guide device of a conveyor belt device. It has already been put into practical use.

This invention is an application of the above conveyor belt to a trolley conveyor, and will be explained below with reference to the drawings shown as one embodiment.

FIG. 1 shows a conveyor belt guide device 1 used in this invention, in which a holder 2 is fixed to a pedestal 3 with bolts 4.

The holder 2 has two opposed ball bearings 5, 5.
A bead 7 with a raised lower part and a substantially U-shaped cross section is provided on the upper end of the belt 6, and the raised portion 8 of the bead 7 is attached to the side surfaces 9, 9 of the ball bearings 5, 5.
is maintained.

This bead 7 has appropriate elasticity and is made of a wear-resistant material.

The ball bearings 5 are disposed opposite to the belt 6 in symmetrical positions, and are mounted on the holder 2 at an appropriate angle with respect to the belt 6.

Further, a hanging tool 10 is attached to the lower end of the belt 6, and a hook 11 is hung thereon.

A plurality of guide devices 1 configured as described above are fixed with bolts 4 to a pedestal 3 which is constructed from a ceiling 12 by hanging tools 13 and 13 as shown in FIG.

A drive pulley 15 supported by a bearing 14 is provided at the front end of the pedestal 3 (left side in the drawing).
5 is driven and rotated by a motor 16 placed on the pedestal 3.

Furthermore, a rubber lining 1 is provided on the surface of the drive pulley 15.
7 is applied to increase the frictional force with the belt 6, and the part located on the raised part 8 of the bead 7 of the belt 6 is
A recessed portion 18 is formed.

In addition, the rear end of the pedestal 3 (on the right side of the drawing)
9 is supported by a bearing 20, and this return pulley 19
A concave portion 21 is formed on the surface of the belt 6 at a portion located at the raised portion 8 of the bead 7 of the belt 6 in the same way as the drive pulley 15, but no rubber lining is provided.

Next, the operating state of the belt type trolley conveyor configured as described above will be explained.

The belt 6 with the bead 7 formed on the upper edge is attached to the ceiling 12.
When the range of the frame 3 suspended from the frame 3 is guided and rotated by a plurality of guiding devices 1, the raised portions 8 of the beads 7 come into contact with the side surfaces 9, 9 of the ball bearings 5, 5. , this raised portion 8 is held on the side surfaces 9,9.

The force that the ball bearing 5 receives from the bead 7 is the force that is applied to the side surface 9 of the hall bearing 5, and the weight of the belt 6 body is applied in the vertical direction, so the force from the bead 7 is perpendicular to the side surface 9. It does not act and becomes a resultant force that is closer to the belt 6 side.

However, as an effect of the hall bearing 5, even if a force from the belt 6 is applied from a direction perpendicular to the side surface 9, the rotation of the ball bearing 5 is not impaired, and the belt 6 is guided smoothly.

Further, since the bead 7 has appropriate elasticity and is made of a wear-resistant material, the degree of wear caused by contact with the side surface 9 of the ball bearing 5 is small, and noise is also small.

Further, a rubber lining 17 is provided on the surface of the drive pulley 15, and a large frictional force acts between the drive pulley 15 and the belt 6 to help drive the belt 6.

Furthermore, a recess 1 is provided in the portion of the bead 7 located at the raised portion 8.
8, the entire bead 7 enters into this recess 18, so that the drive pulley 15 can operate smoothly.

Therefore, the drive pulley 15 is operated by the power of the motor 16, and the belt 6 with the bead 7 is moved between the drive pulley 15 and the return pulley 1 through the plurality of guide devices 1.
It will rotate between 9 times.

In addition, since pulleys are used for the drive and return positions, the turning radius required when turning the conveyor can be significantly smaller than when using a checker 7, etc., and even when the conveyor is curved, Since a belt is used, there is no need to form the guide rail to match the curve, and this can be done simply by changing the arrangement of the guide device 1.

Furthermore, due to the structure of the chain type trolley conveyor device, it is not easy to move it in the left/right or up/down directions because the lubricating oil scatters, but in this invention, the guide device '1 and the pulley Depending on how they are arranged, the running direction of the belt can be freely changed horizontally, vertically, and horizontally without causing the supplied oil to scatter.

Furthermore, since the belt 6 on which the bead 7 is formed is relatively lightweight, it can be easily attached during construction.

As mentioned above, the belt type trolley conveyor according to this invention is very advantageous in terms of noise prevention, range of use of the conveyor device, environment, construction of the conveyor device, etc., and has excellent practical effects.
