The present invention relates to an apparatus for collecting a sample from a sheet rubber rolled with refining rubber, and in particular, a sampling unit for collecting a sample is separately installed in a feeding conveyor to which sheet rubber is transported to increase the reliability of the sampling process. The present invention relates to a sampling device for sheet rubber, which can be unmanned.

In general, the refining rubber required for the manufacture of tires is composed of natural rubber and additives of various chemicals in a half-barrier mixer, and thus the refining rubber is rolled in a sheet form through a rolling mill to feed the feeding conveyor. The ride is carried to the next process.

However, the sheet rubber compounded and rolled in the half-barrier mixer is sampled once per batch by a sampling unit integrally installed in the feeding conveyor while being transported in the feeding conveyor.

That is, the equipment for collecting the sample as described above is arranged in the feed conveyor 23 is inclined slightly below the single mill (Single Mill) 21 to roll the refining rubber as shown in (a), (b) of FIG. On this feeding conveyor 23, a batch separating device 24 for dividing one batch of the sheet rubber 22 rolled by the single mill 21 is provided, and a predetermined distance from the batch separating device 24 is provided. Some of the sheet rubber 22 conveyed by the feeding conveyor 23 is provided with a sampling unit 25 for collecting.

Here, the sampling unit 25 is LM (Linear Motion) installed in the transverse direction to the frame 27 extending upward from both sides of the feeding conveyor 23, as shown in (a), (b) of FIG. A guide rail 27a in the form of a guide, a first transfer member 31 mounted on the guide rail 27a so as to be slidable left / right via a first air cylinder 30, and the first transfer member ( 31, a second transfer member 35 which can slide up and down via a guide member 34 installed vertically by a second air cylinder 33 installed on the upper portion of the second transfer member 35, and is mounted on the bottom of the second transfer member 35. Feeding conveyor 23 so that the vacuum cylinder 36 and the hollow knife 32 at its tip, and the sheet rubber 22 which is transported by the feeding conveyor 23 to the lower portion of the knife 32 It consists of a lower plate 37 fixed to the lower side of the frame.

In addition, a sample feeding conveyor 38 is provided at the lower side of the feeding conveyor 23 to transfer a sample of the sheet rubber 22 collected from the sampling unit 25.

Therefore, in the process of taking a sample from the sheet rubber 22, first, the sheet rubber 22 rolled by the single mill 21 is transported on the feeding conveyor 23, and then transported on the feeding conveyor 23. One batch of the sheet rubber 22 is detected by the batch separator 24 on the feeding conveyor 23, and the feeding conveyor 23 is stopped. At this time, the sampling unit 5 has a first air cylinder 30. The first conveying member 31 is moved in parallel to the upper space of the feeding conveyor 23 by the operation of the guide rail 27a, and then the second conveying member 35 is operated by the operation of the second air cylinder 33. Is lowered along the guide member 34 so that the knife 32 abuts against the lower plate 37 to cut the sheet rubber 22 while being cut by the operation of the vacuum cylinder 36 supporting the knife 32. The sample is sucked into the hollow knife 32, and the above operation is performed in the reverse order. The sample sucked into the knife 32 is moved to the upper part of the sample feeding conveyor 23 and dropped on the sample feeding conveyor 38 by the discharge of the compressed air after the vacuum release of the vacuum cylinder 36. The sample feeding conveyor 38 transfers the sample to the workshop for inspecting the sample.

However, in the equipment for collecting the sample from the sheet rubber 22 on which the refined rubber is rolled as described above, since the sampling unit 25 itself is installed integrally on the feeding conveyor 23, When collecting, the exact position setting is disturbed between the lower plate 37 which is in contact with the knife 32, so that the sampling is difficult, and even when the sample is cut off, the viscosity of the rubber is not completely cut off from the sheet rubber 22. The sampling unit 25 in the sheet rubber 22 which is stronger than the suction force of the sample by the vacuum cylinder 36 and is not smoothly sucked into the knife 32 and is transferred onto the feeding conveyor 23. There was a problem that an unreasonable shock is transmitted to the feeding conveyor 23 due to the impact applied when taking the sample through the medium.

The present invention has been invented to solve the above problems, by separately installing a sampling unit for taking a sample separately from the feeding conveyor for transporting the rolled sheet rubber, the position between the knife and the lower plate is exactly the same It is an object of the present invention to provide a sampling device for sheet rubber that can improve the reliability of sampling.
