Description

DETAILED DESCRIPTION OF THE INVENTION 1. The present invention relates to a sampling method and apparatus for collecting a cylindrical sample by cutting out a sheet material such as rubber.

As a method of cutting out a sheet material and collecting a sample, a method as described in, for example, Japanese Patent Publication No. 13895-1982 is known. This method is
With the sheet material placed on a pedestal in which a rectangular opening is formed, a rectangular hollow cutter blade is inserted into the opening while penetrating the sheet material, and the cutter blade cuts out a rectangular sample from the sheet material. I have to.

However, in such a method, in order to avoid interference between the cutter blade and the pedestal, it is necessary to form an appropriate clearance between the cutter blade and the pedestal. In the case of a sticky material, a small portion of the sheet material adheres to the opening each time it is cut, thereby blocking the clearance and reducing sharpness. Therefore, the adhered sheet material must be removed at regular intervals, resulting in a problem of low work efficiency. In order to solve this problem, a roughly cylindrical cutter with a cutting edge at the tip is moved along its axis until it comes into contact with a flat pedestal on which the sheet material is placed. One possible method is to cut the sheet material into a cylindrical shape using a blade and collect the sample.

However, in this sampling method, if the cutting edge of the cutter has irregularities in the circumferential direction or the surface of the pedestal is uneven, the cutter's cutting edge may not touch the pedestal. Even when they are in contact with each other, there is a slight gap partially between them, which causes a problem in that a thin skin-like uncut portion is partially formed in the circumferential direction.

4. First, there is the process of moving a substantially cylindrical cutter with a cutting edge at the tip to the sampling position perpendicular to its axis, and the process of moving the cutter to the sampling position. cutting the sheet material into a cylindrical shape with the cutting blade of the cutter by moving the cutter along the axis until it comes into contact with a flat pedestal on which the cutter is placed; Second, a flat pedestal on which the sheet material is placed, and a cutting blade for cutting the sheet material. a substantially cylindrical cutter having a tip at its tip, a rotating means for rotating the cutter about its axis, and an approaching/separating means for moving the cutter toward and away from the sheet material by moving the canter along its axis. and a moving means for moving the cutter in a direction perpendicular to its axis.

First, a substantially cylindrical cutter is moved perpendicularly to its axis by a moving means and transported to a predetermined sampling position.Next, the approaching/separating means is activated to move the cutter along its axis until it abuts on the pedestal. move along. As a result, the sheet material placed on the pedestal is cut into a cylindrical shape by the cutting blade provided at the tip of the cutter. Here, if there is a slight gap between the cutting edge of the cutter and the pedestal, a thin skin will remain partially in the circumferential direction at the boundary between the cylindrical sample and the sheet material. Therefore, in the present invention, the cutter is rotated about its axis by the rotation means while being in contact with the pedestal. As a result, the thin uncut portion is cut off, and the sample is reliably separated from the sheet material.

The thickness of the lower part of 2 gradually becomes thinner as it goes towards the lower end.
A cutting edge 43 extending in the circumferential direction is formed at the lower end, that is, the tip. A vertical cylinder 44 is screwed and fixed to the rotary plate 33, and a cylindrical pusher 48 housed in the cutter 42 is connected to the tip of a piston rod 45 of the cylinder 44. As a result, when the cylinder 44 is actuated, the bushing 46 moves up and down within the cutter 42. Reference numeral 51 denotes a holding block housed in the cutter 42 between the intermediate block 41 and the pusher 46, and this holding block 51 has a block that passes through the pusher 4G and has a lower end positioned at approximately the same height as the cutting blade 43. A holding needle 52 is fixed. A slight gap is formed between the holding block 51, the intermediate block 41, the canter 42, and the pusher 46, and as a result,
The holding block 51 and the holding needle 52 are allowed to move slightly in three dimensions. In FIG. 1.5, the collection mechanism 15.

Configure.

Next, the operation of one embodiment of the present invention will be explained.

Now, it is assumed that the sheet material S from which the sample P is to be collected is carried into the sampling device and placed on the pedestal 56, 57.Next, the drive motor B is activated to run the chain 11, and the sampling mechanism 15. Move the support plate 5 horizontally along the rails 2, 3 until the lfi reaches directly above the pedestal 56.57, that is, until it reaches the sampling position. Next, move the cylinder 19 of each sampling mechanism 15.16. The actuation causes the piston rod 22 to protrude, and the cylindrical body 2], the transmission rod 34. The cutter 42 is lowered together along the axis of the cutter 42 to bring the cutter 42 closer to the sheet material S. Then, even after the cutting blade 43 of each cutter 42 contacts the sheet material S, the cutter 42 is further lowered,
The sheet material S is pressed into a cylindrical shape by the cutting blade 43.

At this time, the lower end of each holding needle 52 pierces the sheet material S, and the cutting blade 43 is inserted into the pedestal 56 as shown in FIG.
．． 57, the operation of the cylinder IS is stopped. At this time, if there is a gap at even one location on the circumference between the cutting edge 43 and the upper surface of the pedestal 56, 57, a thin skin-like uncut portion will be generated in the gap. The cylinder 3B is actuated to protrude the piston rod 39, and the cutter 42 is moved through the transmission rod 34, the cylinder 21, and the intermediate block 41 at a predetermined angle around the axis of the cutter 42 while it is in contact with the pedestal 5[i, 57]. Rotate. As a result, the aforementioned thin skin-like uncut portion is cut off, and the cylindrical sample P stored in the cutter 42 is completely separated from the sheet material S. Here, when the sample P rotates integrally with the cutter 42, for example, when the sample P is pierced by the holding needle 52 that rotates together with the cutter 42, as in this embodiment, the thin skin-like The uncut portion is torn off and cut. On the other hand, if the sample P does not rotate integrally with the cutter 42, the thin skin-like uncut portion is cut by the cutting blade 43. After the piston rod 22 of the cylinder 19 is retracted and the cylindrical body 21 and cutter 42 are raised, the drive motor θ is operated to move the support plate 5 to the right in FIG. 1 and stop it at the ejection position. During this transfer, since the holding needle 52 is stuck into the sample P, the sample P does not fall out from the cutter 42. Next, the piston rod 4 of the cylinder 44
5 and lower the pusher 4B.

As a result, the sample P stored in the cutter 42 is pushed out by the pusher 46 and discharged. The sample P discharged in this way slides down on a shooter (not shown) and is stored in a storage can.Next, the piston rod 45 of the cylinder 44 and the piston rod 38 of the cylinder 38 are retracted, and the initial state is Returning to 0 or more is one cycle of the present invention, and thereafter this cycle is repeated and samples P are taken one after another from the sheet material S.

1+ and circle] As explained above, according to the present invention, a sample can be easily and reliably separated and collected from a sheet material.
