[Industrial applications]

 The present invention relates to an article reversing device used for the operation of reversing the front and back of an article while the article is being conveyed by a conveyor.

[0002]

[Prior Art]

 With the development and popularization of computers today, the demand for disks as storage media has also grown significantly.

The substrate that is the base of the disk is required to have high flatness accuracy and no surface roughness. Therefore, at the time of manufacturing the substrate, the substrate whose cross section is warped by press working such as punching from the plate material is removed, and the internal stress remaining in the substrate during the annealing process is removed to ensure the flatness of the warped substrate. It has a high flat plate shape.

In this annealing process, a large number of substrates are laminated with the surfaces having the same warp direction facing each other, and the laminated substrates are formed by an annealing jig formed of a material that is not thermally transformed at the annealing temperature of the substrates. In the pressure-loaded state, heat treatment is performed at a predetermined temperature for a predetermined time to correct the warp of each substrate.

By the way, in order to improve the surface accuracy, it is necessary to stack a plurality of substrates so that the surfaces having the same warp direction face each other, but in the past, the warp was carried in the same direction sent by a conveyor. The substrate is divided into two transportation routes, one of the substrates is turned upside down by an article reversing device, and then the other substrate is combined with a surface having the same warpage, for example, a curved concave curved surface.

The conventional article reversing device is installed between the conveyance end of the first conveyor and the conveyance start end of the second conveyor, and rotates about an angle of elevation of about 180 degrees about a horizontal rotation axis. The article is conveyed by the first conveyor and is stored in the article receiving section, and the front and back of the article are turned upside down by rotating through the upper side about the rotation axis and rotating 180 degrees. The item is being moved.

[0007]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, there is a problem that the operating range of the article receiving portion is required to be wide, the configuration is complicated, and the driving cost is high. In addition, there is a problem that it takes time to reciprocate the article receiving section and productivity is poor.

The present invention has been made in view of these points, and an object of the present invention is to provide an article reversing device having a simple configuration, capable of operating in a small space, low cost, and high productivity. To aim.

[0009]

[Means for Solving the Problems]

 The article reversing device of the present invention is located between the first conveyor and the second conveyor, and reverses the front and back of the article conveyed by the first conveyor and sends the article to the second conveyor. The guide roller that faces the first conveyor and is driven by the first conveyor, and the first conveyor and the guide roller temporarily support the article extruded ahead of the conveyance end portion of the first conveyor, and then reverse the article to the second roller. It is characterized in that it is provided with a reversing support member which is provided at a reversible falling position so that it can be dropped onto the conveyor.

[0010]

[Action]

 According to the article reversing device of the present invention, the article is squeezed between the guide roller and the first conveyor and can be extruded in a horizontal state ahead of the conveyance end portion of the first conveyor. The tip portion is placed on the upper side of the reversing support member installed at the reversible dropping position and is temporarily supported. After that, when the article is completely pushed out into the space, the article is reversed by its own weight, and the front and back sides of the article are turned over to the transport start end portion of the second conveyor before settling.

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings.

1 and 2 show the configuration of an embodiment of the present invention. In this embodiment, an article in which a disk substrate is inverted is shown.

In the present embodiment, in order to convey the disk substrate 1 by the conveyor, two belt conveyors 2a, 2b are provided whose ends are orthogonal to each other in the proximity position. Of these, the transport end portion of the first belt conveyor 2a, which is installed at the upper position, which corresponds to the outlet of the disk substrate 1, is the transport start end which corresponds to the receiving end of the disc substrate 1 of the second belt conveyor 2b, which is installed at an appropriate distance below. It is located above the department.

The belt conveyors 2 a and 2 b have a belt 3 wound around a pair of pulleys 5 and 5 arranged at both ends of a pair of side plates 4 and 4, respectively. In the first belt conveyor 2a, a bearing member 6 extending vertically upward is fixed to the end of the side plate 4 in the running direction of the belt 3, and the bearing member 6 has a first bearing member 6a. 1-belt A rotary shaft 8 penetrating through the central portion of a large-diameter guide roller 7 that is pressed against the upper surface of the belt 3 of the conveyor 2a and is driven is supported in a cantilever shape. The guide roller 7 is formed of an elastic material such as sponge or a relatively soft material in order to prevent the disk substrate 1 from being damaged when being pressed against the belt 3. In this embodiment, the guide roller 7 is pressed against the upper surface of the belt 3 of the first belt conveyor 2a as described above. However, depending on the thickness of the article, the guide roller 7 may be spaced apart from the upper surface of the belt 3. In addition, the traveling of the belt 1 may be transmitted to be rotationally driven by a transmission mechanism (not shown).

A bracket 9 is projectingly provided in the transport direction of the disk substrate 1 at the end of the side plate 4 facing the bearing member 6 of the first belt conveyor 2 a. In this bracket 9, a rod-shaped guide rod 10, which is a kind of reversing support member, is ahead of the first belt conveyor 2a in the conveying direction, and the disc substrate 1 is once supported at the upper part and then reversed to turn the second belt. A cantilever-like projection is provided at a position where it can be reversed and dropped onto the conveyor 2b. To explain further, the guide rod 10 is installed in a substantially horizontal plane with the upper surface of the belt 3 of the first belt conveyor 2a, and is substantially parallel to the guide roller 7. The guide rod 10 is formed by covering the outer peripheral surface of a metal rod with plastic or the like in order to protect the guide rod 10 when it contacts the disc substrate 1. In addition, by making the guide rod 10 serving as the reversing support member adjustable and movable in the direction of contacting and separating from the first belt conveyor 2a, various articles having different diameters can be reversed.

Next, the operation of the present embodiment having the above-mentioned configuration will be described.

As shown in FIG. 2, the disk substrate 1 moved by the first belt conveyor 2 a is pinched by the guide roller 7 and the belt 3 at the end of the first belt conveyor 2 a in the traveling direction, and the belt 3 While moving the position supported by the drive of the guide roller 7 driven by the belt 3 and the belt 3, the belt 3 is extruded in a horizontal state into the space beyond the conveying end portion of the first belt conveyor 2a. Immediately before the disc substrate 1 is completely pushed out, the tip of the disc substrate 1 is mounted on the upper portion of the guide rod 10 installed at the reversible dropping position and temporarily supported, and the disc substrate 1 is completely pushed into the space. When it is taken out, the disc substrate 1 is rotated by its own weight as shown by the thick arrow in FIG. 2, and settles on the end of the upper surface of the belt 3 which is the receiving portion of the disc substrate 1 of the second belt conveyor 2b. To do. After that, the disk substrate 1 is conveyed by the second belt conveyor 2b to the lamination position in the next annealing step.

On the other hand, another two belt conveyors (not shown) extending in parallel with the first belt conveyor 2a and the second belt conveyor 2b are arranged, and these two belt conveyors (not shown) are arranged. During this period, goods are delivered without being reversed. Then, the disk substrate 1 is alternately taken out from the downstream end of the second belt conveyor 2b and the downstream end of the downstream belt conveyor (not shown) and sent to the next annealing step.

According to the article reversing device of this embodiment, the guide roller 7 is rotated by being driven by the first belt conveyor 2a, and the reversing of the article utilizes the weight of the article. Therefore, no other power source is required for the driving force of the main body of the apparatus, so that no running cost is required. Further, the materials of the guide roller 7 and the guide rod 10 are carefully selected, the quality of the product is not impaired, the structure is simple, and a large space for driving is not required. In addition, the product can be operated at the speed at which the conveyor is running, and work can be performed without stopping the flow of articles, so that productivity is also good.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but can be modified as necessary. For example, a member having a configuration other than the guide rod 10 can be used as the inversion support member.

[0021]

[Effect of the device]

 As described above, according to the present invention, the guide roller that pushes out the article in the horizontal state ahead of the conveyance end portion of the first conveyor while pressing the article is rotated by following the first conveyor. Since it does not require any other power source, it does not require a running cost, its configuration is simple, and it does not require a large space. Further, the conveyor can be operated at a traveling speed, work can be performed without stopping the flow of articles, and productivity is improved.
