On the other hand, in the case of FIGS. 5(a) and 5(b), the difference in width is used, and the width regulating plate 5a,
Separated material 3 that does not pass between 5b and 5b is automatically removed from the conveyor 1.

[Problems to be Solved by the Invention] In the conventional method as described above, a thin product such as a plus deck film, for example, a floppy film with a thickness of 0.1 mm as shown in FIG. It was difficult to separate the disk (product) 6 from the punched-out (small part) 7 at the center of the floppy disk 6 as shown in FIG. 6(b). This is because they are thin and tend to overlap as shown in FIG.

This invention solves these problems.

[Means for Solving the Problems] A device for separating small parts in a transported product according to the present invention is a device for separating small parts in a transported product, which separates small parts mixed in a thin product during transportation of the product. The carry-in side of the rear conveyance line is positioned below the product discharge side of the front conveyance line that conveys the product, and a guide is provided between the carry-in side of the front conveyance line and the carry-in side of the rear conveyance line. The guide body is provided with an arcuate inner circumferential surface that receives the product carried out from the upper front conveyance line, moves it downward, turns it upside down, and transfers it onto the lower rear conveyance line, It is characterized by a hole that allows small parts in the transported product to fall downward.

[Function] The device for separating small parts in conveyed parts of the present invention separates the small parts conveyed together with the product by turning the product upside down using the guide body.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. This embodiment is an application example in which the apparatus is installed in a floppy disk manufacturing line in order to separate the floppy disk 6 and the punching waste 7 described above.

First, an overview of the entire floppy disk manufacturing line will be explained based on FIG. 3.

The floppy disk 6 is formed by punching out a polyester film 9 into a circular shape using a press body 8. At the same time as the punching, punching scraps 7 are produced. The polyester film 9 enters the press body 8 from the uncoiler lO through the accumulator 11, and is intermittently fed by the feed device 12. The remaining polyester film 9 after being punched out is wound up by a coiler 13. The floppy disks 6 punched out by the press body 8 are transferred to the accumulating device 15 into the pin container 14, and are stacked onto the bin container 14 in predetermined numbers so that the pins of the pin container 14 are inserted into the central hole. The pin containers 14 and the pin containers 14 are then conveyed onto the stacking device 15 to the left in the figure. The punched scraps 7 are conveyed from the press body 8 to the accumulating device 15 together with the floppy disk 6, and are automatically separated from the floppy disk 6 during the conveyance.

As a device for separating the punching residue 7, a separating device 16 according to the present invention is employed.

The separation device 16 is constructed as shown in FIGS. 1 and 2.

A conveyance line for conveying the floppy disk 6 is provided with a belt conveyor 17 located above and a belt conveyor 18 positioned below.The belt conveyor 17 forms a front conveyance line, and the belt conveyor 18
This forms the rear conveyance line. The belt conveyor 17 has two belts 1 separated by a predetermined distance e.
7a and 17b are configured to circulate in the direction of arrow A. Similarly, the belt conveyor 18 is configured to circulate two belts 18a and 18b separated by a predetermined distance e in the direction of arrow B. The interval e is larger than the punching dregs 7, and forms a hole through which the punching dregs 7 fall downward.

The upper belt conveyor 17 has an output side on the left side in the figure, and the lower belt conveyor 18 has an input side on the left side in the figure, and a guide body 19 is provided between the output side and the input side. It is provided.

The guide body 19 is composed of two semicircular arc-shaped guide members 19a and 19b supported by a base (not shown). These guide members 19a and 19b are spaced apart from the punched scraps 7 by a large distance, their upper ends are located slightly above the delivery side of the belt conveyor 17, and their lower ends are located on the delivery side of the belt conveyor 18. The floppy disk 6 from the upper heald conveyor 17 is dropped along the inner peripheral surface of the arc and transferred onto the lower belt conveyor 18.

In addition, in this example, below the belt conveyor 18,
A belt conveyor (not shown) is provided for conveying the floppy disk 6 from the right to the left in FIG. A similar guide body 19 is provided.

Next, the effect will be explained.

The floppy disk 6 from the press body 8 is conveyed along with the punched scraps 7 by a belt conveyor 18 in the direction of the arrow. During the conveyance, the belts 17a, 1
The punching scraps 7 located between the floppy disks 7b fall from between the floppy disks 7b and are automatically separated from the floppy disk 6. Second
As shown in the figure, the punching scraps 7 on the belts +7a, 17b and the punching scraps 7 on the floppy disk 6 are conveyed as they are together with the floppy disk 6 and are carried out from the left side of the belt conveyor 17.

The floppy disk 6 carried out from the belt conveyor summer 7 is received by the inner peripheral surfaces of the circular arcs of the guide members 19a and 19b, falls while being guided along the inner peripheral surfaces, and is placed on the belt conveyor 18 below. . The floppy disk 6 is turned upside down while moving along the guide members 19a, 19b. At this time, the punched scraps 7 carried out together with the floppy disk 6 separate from the floppy disk 6 and fall from between the guide members 19a and 19b. Therefore, the punching scraps 7 as shown in FIG. 2 are separated from the floppy disk 6, and the floppy disk 6 is conveyed in the direction of arrow B by the belt conveyor 18 while being upside down. The belt conveyor 18 has the function of separating the punching scraps 7 similarly to the belt conveyor 17 described above.

The floppy disk 6 carried out from the belt conveyor 18 is further turned upside down by a guide body 19, and then conveyed to the stacking device 15 by a belt conveyor (not shown). Therefore, the guide body 19 also has the same effect of separating the punching dregs 7 as described above.

By such multi-stage separation action, the punching dregs 7 are completely separated from the floppy disk 6.

[Effects of the Invention] As explained above, the device for separating small parts in conveyed parts of the present invention is configured to separate the small parts conveyed together with the product by turning the product upside down using the guide body. , the target is a thin product, such as a polyester film such as a floppy disk, and the thickness is 0.
