Abstract

PURPOSE:To make it possible to turn an article to be conveyed by an angle of 180 deg. in a small space, by winding and suspending a flexible and touch disc- like mat around and from the drive shafts of two outgoing and oncoming conveyers which are arranged in parallel with each other, between end parts of both conveyers. CONSTITUTION:A drive motor 13 rotates an outgoing conveyer 2. Further, the rotation of a drive sprocket wheel 15 fitted on a motor shaft 14 is transmitted to an outgoing drive shaft 9 journalled to the upper edge 7 of a table 6 through a chain 17 and a driven sprocket wheel 16, and is also transmitted to an oncoming drive shaft 10 through bevel gears 11, 12 so that sprocket wheels 20, 21 are rotated in opposite directions with respect to each other. Then, a disc-like mat 18 meshed with the wheels 20, 21 through a curved chain 19 is rotated while it slides on the table 6, and therefore, an article to be conveyed is shifted onto the oncoming conveyer 3 from the outgoing conveyer 2 through the disc-like mat 18, thereby it is possible to turn the conveying direction of the article to be conveyed by an angle of 180 deg..

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a 180' turn system with a unique structure that can be widely used in the distribution and conveyance industry when changing the conveyance direction of an article by 180 degrees using a simple device. It is related to conveyors.

(Prior art) Conventionally, in order to change the running direction of a conveyor by 180 degrees, a large number of rollers are arranged in a fan shape at the tips of parallel conveyors on the outbound and return trips, and each of these rollers is driven to rotate. A conveyor was used, but this not only increased equipment costs (but also had a large turning radius and required wasted space, making it uneconomical).

(Problems to be Solved by the Invention) The present invention is a device that can change the traveling direction of a conveyor by 180' using a simple device and in as little space as possible, and its development has been desired.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides two conveyors installed in parallel on the outbound and return trips, each of which has a horizontal surface at the base end of the table. Drive shafts that rotate in opposite directions are provided, and a curved chain is attached to the outer periphery of a strong and flexible disc mat made of synthetic resin, leather, or canvas, with the drive shaft surface as a boundary, and the outer end of the drive shaft is This curved chain is meshed with a sprocket wheel that is fixed to a sprocket wheel.

(Structure of the invention) The configuration of the present invention will be explained based on drawings of embodiments.

Embodiment 1 As shown in FIGS. 1 to 5, the 180° turn conveyor 1 has an outbound conveyor 2 and a return conveyor 3, and a distal end 4 of the outward conveyor 2 and a base end 5 of the return conveyor 3. The ends 4 of both conveyors 2 and 3 are aligned and arranged in parallel.
, 5 with a slight gap between them, a table 6 is installed with its upper surface slightly lower (horizontally) than the upper surface of both conveyors 2.
A vertical intermediate rotating shaft 8 is reversibly vertically disposed at the center of the upper edge 7 of the table 6 facing the ends of both the conveyors 2 and 3, and the outbound conveyor 2 and the return conveyor 2 are attached to the upper edge 7 of the table 6. An outgoing drive shaft 9 and a return drive shaft 10 are rotatably attached to each other in close proximity to each end 4.5 of the conveyor 3, and a bevel gear 11.11 fixed to the inner end of each is attached to the vertical intermediate rotation shaft 8. Bevel gear 12 fixed to the upper end
A chino 17 is disposed between a drive sprocket wheel 15 which is simultaneously engaged with the motor shaft 14 of the drive motor 13 provided on the side of the outbound conveyor 2, and a driven sprocket wheel 16 which is fixed to the outbound drive shaft 9. Hang it up.

On the other hand, a sprocket wheel 20 having a curved chain 19 attached to the outer periphery of a strong and flexible disk mat 18 made of canvas, leather, or synthetic resin is fixed to the outer end of the outgoing drive shaft 9, and a sprocket wheel 20 is fixed to the outer end of the return drive shaft 10. The fixed sprocket wheels 21 are meshed with each other, and ten of the disk mats 18 are placed on the upper surface of the table 6, and the lower half is allowed to hang vertically downward by its own weight.

Embodiment 2 Embodiment 2 is equipped with another example of a drive device, and as shown in FIG. A bevel gear 1 is defined at the upper end of a vertical drive rotation shaft 23 that is upright so as to be rotatable through the drive shaft.
1. Mesh 11 together. -Other structures are the same as in Example 1.

In the figure, 25 is a guide case, 26 is a conveyor rotating shaft of the outward conveyor '2, 27 is a conveyor rotating shaft of the returning conveyor '3, and 28 is the underframe of the table 6 in red.

(Operation of the invention) Example 1 The operation of the invention will be explained based on the drawings of the embodiment. As shown in FIGS. 1 to 5, the outgoing conveyor 2 is driven and rotated by the drive motor 13, and the motor shaft The rotation of the drive sprocket wheel 15 attached to the
The forward drive shaft 9 supported on the upper edge 7 of the table 6 is rotated in the direction of arrow R via the driven sprocket wheel 16, and the return drive shaft 10 is rotated relative to each other in the direction of arrow R' via the bevel gears 11 and 12. Rotate in the opposite direction. Sprocket wheels 20, 21 fixed to the respective outer ends of the forward drive shaft 9 and the return drive shaft 10 rotate at the same speed in the direction of arrow R and arrow R', respectively.

A disc mat 18 made of pliable and strong Larino (registered product name) has an upper half and a lower half hanging down on the table 6, and a curved chain 19 provided on the outer periphery of the disc mat l-18 is attached to the sprocket. Wheel 20.21
Since they are in mesh with each other, the disc mat 18 rotates in the direction of arrow S while sliding on the table 6.

After leaving the table 6, the disc mat 18 is flexible and sag, but the curved chain 19 on the outer periphery maintains its engagement with the sprocket wheels 20, 21, so the disc mat 18 rotates in the direction of arrow S. persists.

Since the outbound conveyor 2 and the return conveyor 3, which are arranged close to the upper edge 7 of the table 6 with a gap between them, run in the directions of arrows A and B, respectively, they are continuous in the direction of rotation of the disc mat 18. The conveyed object W, which has been conveyed in the direction of the arrow on the outgoing conveyor 2, is transferred at the tip 4 onto the disk mat 18 which is rotating in the direction of the arrow S, and the transferred object W is transferred to the disk mat 18, which is rotating in the direction of the arrow S. At the same time, it is guided by the guide case 25 in a semicircle in the direction of the arrow S, and rotates to the return conduit 73.
The base end 5 of the object W is transferred onto the return conveyor 3 running in the direction of arrow B, and the object W is transported 180 degrees in the direction of conveyance. 'Converted.

Embodiment 2 As shown in FIG. 6, a bevel gear meshes with a hel gear 24 at the upper end of a vertical drive rotating shaft 23 rotated by a drive motor 13' below the center of the upper edge 7 of a table 6 via a reducer 22. 11.11, the forward drive shaft 9 and the return drive shaft 10 rotate in opposite directions at the same speed to rotate the disc mat 18 in the direction of arrow S. Other operations are the same as in Example 1.

(Effect of the invention) Since the present invention has the above-described configuration, it has the following advantages.

(1) A flexible and strong disc mat is hung around the small-diameter forward drive shaft and return drive shaft, so that objects to be transported can move smoothly.

(2) Since the return belt and the return belt are vertically lowered, it does not take up much space and does not require a return mechanism. (self-weight tension) (3) Turning radius is O
~ Mats can be manufactured to any size possible.

(4) Since it is rotated by a carburetor, no load is applied to the disc mat.

(5) The table does not necessarily have to be horizontal.

(6) Due to its simple structure, it can be manufactured at extremely low cost.

(7) Maintenance is very easy.

(8) The surface is clean without being touched.
