DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport device that automatically transports objects such as cylinders.

In assembly work where cylinders are conveyed by a trolley conveyor while being painted, dried, etc., the work of attaching and detaching the conveyed cylinders to and from the conveyor's hanging fixture was previously done manually, but now this work can be done automatically. It would be convenient if it could be installed and removed. In particular, in cases where the processed material is at a high temperature, such as during baking painting, it is difficult to handle it manually, so the effect is significant.

The present invention has been made in view of the above two circumstances, and provides a conveying device that can automatically load and remove articles from a conveyor.

That is, the conveying device according to the present invention includes a moving body that is driven along a predetermined trajectory, and a hanging tool attached to the moving body, and the hanging tool has an engagement notch that is open in one direction. A hanging fitting for the transported object having a shaft-shaped hanging fitting is fitted into the notch, and a large-diameter locking part provided at the top of the shaft is locked to the peripheral edge of the notch. This is a conveyance device that rotatably suspends and conveys a conveyed object in a horizontal plane, and the hanging tool has a rod-shaped projection that projects laterally, and a ship's corner shape with a smooth curve at the end. is provided with a guide plate that is sharpened to protrude in a direction perpendicular to the bar-shaped projection, and if the engagement notch is oriented in the opposite direction to the predetermined direction at a predetermined position j6 of the conveyance path, the bar-shaped A fixed protrusion that makes contact with the protrusion causes the hanging holder to rotate approximately 1/4; and the end of the guide plate of the hanging holder, which is rotated approximately 1/4 by the fixed protrusion, abuts and rotates the hanging holder in the same direction. It is characterized in that a fixed guide with four parts is provided to further rotate approximately 1/4 of a turn.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings. FIG. 1, FIG. 2, and FIG. 3 show an example of a conveyance device according to the present invention, and this conveyance device 1 includes a moving body 3, which moves along a track 2 provided on a conveyance path, It consists of a removable hanging tool 4 that can be attached to the movable body 3, and a fixed guide tool 5 that is provided at a predetermined position on the movement path of the hanging tool 4.

The movable body 3 includes front and rear hanging plates 12 that are pivotally supported by rollers 11 that are pulled by a chain 10 and rotated within a track 2, and a flat plate 9 to which the hanging plates 12 are pivotally connected. A pair of plates 15, 15 are pivotally attached to the portion. Plate 1
A shaft 14 is fixed to the lower part of the shaft 14, and a gear 17 having a roughly U-shaped hanger 16 fixed to its lower surface is provided at the lower part of the shaft 14 so as to be rotatable in the horizontal direction. Shaft 14 and gear 1
A bushing is interposed between gear 17 and a bearing 18 is mounted on the lower side of gear 17, so gear 1
7 can be smoothly rotated around an axis 14.

The hanging tool 4 is a hanging plate whose tip is curved to form a hook part 21a at the upper end of a support column 20 which is bent at the center and shifted in the left-right direction from the axes of the upper and lower parts. 21 is fixed to the movable body 3, and is hung from the movable body 3 by hooking the hook portion 21a of the hanging plate 21 to the hanging tool 16 of the movable body 3. A rod-shaped protrusion 22 is provided on the back of the hanging plate 21 and protrudes in the t4 water direction, and at the upper part of the support column 2o below the rod-shaped protrusion, both ends are shaped like a bow with a smooth curve. A guide plate 23 which is sharpened and has a spindle shape in plan view is provided horizontally at an angle of 1η with the rod-shaped projection 22. The suspension plate 24 welded to the lower end of the support column 2o has a V-shaped notch 25 that opens to one side, and the deep part of the notch 25 is a U-shaped locking hole 2B. There is. This locking hole 2
The innermost part 2 [1a of the support 21 is formed in the shape of a round hole concentric with the upper part 2'Oa of the support 21, and a dish-shaped chamfer 27 is applied to the circumference thereof. The shaft portion 31 of the hanging fitting 6 attached to the top of the transported object 29 is connected to the locking hole 26.
By fitting the slanted bottom surface of the large-diameter flange-like locking part 32 provided at the upper end of the hanging fitting 6 to the chamfered part 27, the transported object 28 can be reliably suspended. It has become.

The fixed guide plates 5 are a set of two arranged in series, one at two locations, one at the start position and one at the end of transport of the transported object.
They are set up in groups. The two fixed guide plates 5.5' consist of a straight line part 33 parallel to the moving path of the fourth hanging tool, and a front end part 34 and a rear end part 35 formed by an arcuate curve. It is attached to a hanging attachment member 40. An appropriate distance is set between the two 5.5' so that the pivoting movement of the guide plate 23, which will be described later, can be carried out smoothly. Further, the fixed guide plate 5 on the front side of the transfer path is provided with a fixed protrusion 3B protruding upward near the rear end.

The fixed guide plate is not limited to the one shown in the illustration, but the guide plate 2
It may be of any shape as long as it guides 3 to turn well. 2 and 6 show the conveying device l near the conveyance start position, and the fixed guide plate 5.5' at the conveyance end position is as shown in FIGS. 3 and 7. The fixed guide plates 5, 5' at the transport start position are provided on the opposite side to the route.

The transport device 1 of this embodiment is for transporting gas cylinders, and the hanging fitting 6 is attached to the top of a gas cylinder 29 as an object to be transported, as described above. This cylinder 2
8 are sequentially supplied to a predetermined transport start point S by mechanical force or manually. Each hanger J44,4. ... flows along the track with its suspension plate 24 facing various directions, but when the ~ part of the guide plate 23 comes into contact with the front part 34 of the fixed guide plate 5, the suspension plate 24 is oriented in various directions. X4 rotates around the axis 14 of the movable body 3, and the side edge of the guide plate 23 comes to align with the straight part 33 of the fixed guide plate 5. At this time, the hanging plate 24 of the hanging fixture 4 has a V-shaped notch. When B25 is facing the normal direction in the direction of travel (D), the hanging holder 4 remains in the 1-

reach. However, when the hanging plate 24 faces in the opposite direction (A), the rod-shaped protrusion 22 of the hanging fixture 4 hits the fixed protrusion 36 of the fixed guide plate 5, and the hanging fixture 4 moves while rotating (B). ). As it continues to move further, the guide plate 23, which is inclined with respect to the direction of movement, comes into contact with the front end of the fixed guide plate 5' (C), rotates further in the same direction, and finally the hanging tool 4 is just It will be reversed (rotated 180 degrees) and will now face the normal direction. The suspension plate 24 facing in the direction of 1 waits at the transport start point S and guides the shaft part 31 of the hanging fitting 6 of the cylinder 211 from the νJ missing part 25 to the locking hole 26, and lifts the cylinder 28. It is lifted up.

The lifted cylinder 28 is conveyed along the track, and during the conveyance route, it is subjected to treatments such as pretreatment such as LF sandblasting, painting (P), and drying (Q).

If a rack that meshes with the gear 17 is installed as necessary at the position where these processes are performed, the gear 17 will move as the process progresses.
7 rotates f, so that the suspended conveyance object can be rotated within a horizontal plane.

Regarding orientation alignment at the transport end position, the same explanation as for the transport start position can be made. In other words, the force of the hanging tool 4 (F) facing in any direction (when it reaches the conveyance end point G, the rod-shaped projection 22, the fixed projection 36, and the guide plate 23
Due to the function 1 of the fixed guide plates 5 and 5', it faces in the normal direction (in this case, the direction opposite to the V-shaped notch 25 force-progressing direction). Since a blocking device 41 for the cylinder 29 is provided at the conveyance end point G, the suspension plate 24 with the notch 25 facing backward is automatically removed from the suspension fitting 6 of the cylinder 29. In this way, the conveyance is completed. Immediately after baking the cylinder is heated to about 100°C, it is difficult to handle it manually.

It would be extremely convenient if it could be automatically removed like this device 1.

In addition, in this conveying device t, the rod-shaped projection 22 and the fixing projection 38, which are members for orientation alignment, and the guide plate 23 and the identification guide plate 5.5' engage with each other to hold the hanging tool 4 in a fixed direction. The shapes and positions of these members are not limited to those shown in the figures, as long as they can be aligned. For example, instead of the hanging tool 24, a roughly V-shaped support 24' as shown in FIG. 8 may be used to suspend the conveyed object.

Further, by providing a new orientation control member at a different position, orientation can be controlled in multiple stages.

As is clear from the following description, the conveying device according to the present invention includes: - a hanging device that allows the conveyed object to be attached and removed only in summer orientation; and a direction control device that aligns the conveyed object in a fixed direction. This makes it possible to automatically remove transported objects. Further, this conveyance device can also be used as an article orientation device depending on the case.
