Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for conveying thin objects such as thin plate coils.

[Conventional technology]

Conventionally, when manufacturing ERW pipes and flexible pipes, etc., a thin plate coil with a diameter (2050 to 1600 mm) x width (2400 to 1800 mm) is generally slit to create a thin plate coil with a small width (with a width of 20 mm or less for small items). This is transported by a chain conveyor or the like and sequentially supplied to an electric resistance welded pipe manufacturing machine and a flexible pipe manufacturing machine. In this case, since the narrow thin plate coil is extremely unstable if placed upright, it is usually transferred onto the conveyor horizontally.

[Problem that the invention attempts to solve]

However, the apparatus of the above transfer method has a low coil accommodating capacity and a low transport efficiency.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an apparatus capable of simultaneously and efficiently conveying a large number of thin articles.

[Means for solving problems]

The device of the present invention for conveying thin articles consists of (a) a pair of rails laid in parallel, (b) a pair of endless conveyor chains running on the rails, and (c) a pair of endless conveyor chains that straddle the endless conveyor chains. (d) a guide frame attached to the conveyor chain between the pair of saddles and extending in a direction perpendicular to the traveling direction; and (e) rotating along the guide frame. (f) a pair of side brackets having threaded holes screwed into the screws and movable along the guide frame, and (f) having a screw with left and right reverse threads that are freely attached; The article is characterized in that the side brackets are close to each other and can hold the article.

〔Example〕

In FIG. 1, a rail 2 having a convex portion 2a and a flat portion 2b is provided on the upper surface of a conveyor frame 1, which is laid parallel to the conveyance direction at appropriate intervals.

The conveying device of the present invention includes a pair of saddles 4 and 5 formed at the link part of a pair of endless conveyor chains 3.
and a guide frame 7 attached between a pair of saddles 4 and 5. Traveling rollers 6 are attached to both ends of the shaft that connects the links of the conveyor chain 3. As shown in FIG. 3, the running roller 6 runs on the flat part 2b while sandwiching the convex part 2a of the rail 2.

Each saddle 4, 5 has an inclined saddle surface 4a, 5a.
The saddle surfaces 4a and 5a face each other so as to form a V-shape.

Lower protrusions 7a and 7b on both sides of the guide frame 7
are fixed to link members 8a, 8b connected to shafts supporting the saddles 4, 5, and the guide frame 7 extends perpendicularly to the traveling direction. As shown in FIG. 2, the guide frame 7 has a T-groove 9, in which the bottom portions 10 of a pair of side brackets 10, 11 are inserted.
a and 11a are slidably fitted together. bottom 10
A, 11a has a presser portion 10 extending vertically at the inner end thereof.
b, 11b are fixed, and each presser part 10b,
Support parts 12a, 12b are fixed to both ends of 11b, and each presser part 10b, 11b is attached to the bottom part 10a, 11b.
It is firmly fixed to a. Each presser part 10b, 11
In b, a slit 13 is formed in the center, and the upper end of the slit 13 is widened.

As shown in FIG. 3, vertical plates 7c and 7d provided at both ends of the guide frame 7 rotatably support a screw 14 extending perpendicular to the traveling direction. The screw 14 is the side bracket bottom 1
By screwing into the screw holes provided in 0a and 11a, and rotating the screw 14, the side brackets 10,
11 is adapted to move along a screw 13. Further, since the screws 14 have left and right reverse threads, the screws 14 move toward or away from each other as the screws 14 rotate. Further, a gear 15 is fixed to the screw 14 at the center.

As shown in FIG. 1, a gear 16 is rotatably attached to the conveyor frame 1. Gear 16 is rotated by a suitable drive (not shown). As shown in FIG.
6 rotates the screw 14. 1st
Although only one gear 16 is shown in the figure, there are two gears for loading and unloading.

As shown in FIG. 3, the side bracket 10,
The holding portions 10b and 11b of 11 are provided with an elastic body 17 and an abutment piece 18 to reduce the impact when gripping the thin plate coil.

Here, the operation of the conveying device of the present invention will be explained.

The conveyance device running on the rail 2 first has a gear 15 attached to the screw 14 and a drive gear 16.
It stops at the position where the coils are engaged (coil loading position). At that time, a pair of side brackets 10, 11
is in the open position. A pair of saddles 4 and 5 have several turns of thin plate coils hooked to rods (not shown).
The rod is placed on the side bracket 10,
It is pulled out laterally through the slit 13 of No. 11.
Alternatively, several turns of the thin plate coil may be held together and placed on the saddles 4 and 5. Next, by rotating the drive gear 16, the screw 14 to which the gear 15 is fixed rotates, and the pair of side brackets 10 and 11 approach each other. When the side brackets 10, 11 hold the thin plate coils, the drive gear 16 stops and the conveyor chain 3 resumes running.

When the transport device reaches the unloading position, gear 15 engages another drive gear (not shown) and the transport device stops. Since the driving gear rotates in the opposite direction to the gear 16, the pair of side brackets 10 and 11 are separated from each other, and the thin plate coil inside can be taken out.
The thin plate coil can be removed by means of a rod or by suitable gripping means.

Since the conveyor chain 3 is endless, it returns to the original carrying position by making one revolution on the endless rail 2. From here on, the process described above is repeated.

[Effect of idea]

With the above configuration, the conveying device of the present invention can efficiently convey a large number of thin articles. In particular, since thin articles are held by rotating the screw, holding can be ensured by appropriately adjusting the rotation of the screw depending on the overall thickness of the article.
