DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supplying a sample and an ignition wire to a calorific value measuring device capable of automatically supplying a sample and an ignition wire to a bomb of the calorific value measuring device.

[0002]

2. Description of the Related Art A calorific value is measured by enclosing a sample and high-pressure oxygen in a metal container called a bomb, immersing the sample in a water tank, and energizing an ignition wire inside the bomb to burn the sample.
This is performed by a method of detecting a rise in water temperature at that time. Therefore, conventionally, a sample was manually set on the bomb, and a new ignition wire was set in place of the burnt-out ignition wire.

However, recently, an attempt has been made to automate a part of the calorific value measurement process. For example, in a coal analysis system, a method in which a sample is chucked by a robot hand and supplied to a bomb is adopted. However, this required a large-scale robot, and it was not possible to automatically supply soft and hazy ignition wires, and even when sample supply was automated, all ignition wires were set manually. . For this reason, it was impossible to carry out the calorific value measurement device unattended.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and automatically supplies not only a sample but also an ignition wire to a bomb of a calorific value measuring apparatus without requiring a large-scale robot. The present invention has been completed in order to provide a device for supplying a sample and an ignition wire to a calorific value measuring device capable of performing calorific value measurement completely unattended.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an L-shaped arm which swings in a horizontal plane on the side of a bomb of a calorific value measuring device. A sample chuck for transferring a sample from a sample conveyor to a bomb is provided at a tip, and an ignition wire chuck for transferring an ignition wire from an ignition wire supply device to an electrode of a bomb is provided at a tip of the other arm. .

[0006]

According to the present invention, when the L-shaped arm is swung right and left in the horizontal plane, the sample chuck at the tip of one arm transfers the sample container containing the sample from the sample conveyor to above the bomb. The ignition wire chuck at the end of the other arm takes out the ignition wire from the ignition wire supply device. And L
The sample chuck returns to above the sample conveyor when the squib arm is swung to the opposite side and the igniter chuck has transferred the igniter wire above the bomb. Further, as shown in an example described later, an operation of taking out an empty sample container from a bomb and discarding it can be performed. Therefore, it is possible to automatically supply the sample and the ignition wire to the bomb of the calorific value measuring device.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the illustrated embodiments. 1 and 2, 1 is a bomb of the calorific value measuring device, 2 is a vertical axis provided on the side thereof, and 3 is an L that swings left and right in a horizontal plane about the vertical axis 2.
It is a U-shaped arm. One arm of this L-shaped arm 3
A sample chuck 4 is attached to the tip of 3a, and an ignition wire chuck 5 is attached to the tip of the other arm 3b.

The sample chuck 4 receives a sample container 7 containing a sample from the sample conveyor 6 and transfers it to a position above the bomb 1. The sample conveyor 6 has a U-shaped receiving member 9 and a cylinder at the end of a belt conveyor 8 for transferring the sample containers 7 in a line.
A slide plate 11 driven by 10 is provided.
The sample containers 7 are received in the pockets of the slide plate 11 and slid to the receiving members 9, and the sample chuck 4 can chuck the sample containers 7 at this position. The shape of the sample container 7 is as shown in FIG.

The ignition wire chuck 5 supplies the ignition wire 12 from the ignition wire supply device 13 to the electrode 14 of the bomb 1. As shown in FIG. 3, the ignition wire chuck 5 has two cylinders 15 and 16 which move at right angles to each other, and has a head 17 which can be moved obliquely by these cylinders. The head 17 has a first chuck 18 and a second
A chuck 19 is provided. The ignition wire supply device 13 includes a drum 20 around which a continuous cord-like ignition wire 12 is wound, and a pipe-shaped guide 21. The ignition wire 12 passes through the inside of the guide 21 and protrudes from its tip.

The operation of the ignition wire chuck 5 is as follows. First, at the position indicated by the imaginary line in FIG. 3, the first chuck 18 of the ignition wire chuck 5 chucks the end of the string-like ignition wire 12 protruding from the guide 21 and moves the head 17 together with the head 17 to the position indicated by the solid line. The ignition wire 12 is pulled out of the drum 20 by moving the chuck 18 obliquely. Next, the second chuck 19 chucks the rear part of the ignition wire 12 at the position shown in the figure, and the scissors (not shown) operate to cut the ignition wire 12. Since the cutting point is located at a position slightly distant from the tip of the guide 21, the remaining ignition wire 12 is in a state where the face comes out of the guide 21.

Next, the rotation of the L-shaped arm 3 causes the first chuck 18 and the second chuck 19 of the ignition wire chuck 5 to move the ignition wire.
The bomb 12 is transferred to the upper side of the bomb 1, and the ignition wire 12 is set to the electrode 14 of the bomb 1 (see FIG. 4). At this time, the ignition wire chuck 5 opens the first chuck 18 and the second chuck 19 after lowering the cylinder 16. In order to prevent the ignition wire 12 from sticking to one side of the chuck even when the first chuck 18 and the second chuck 19 are opened, a sticking prevention guide 23 is provided between them.

The operation of the entire apparatus is as follows. First, the slide plate 11 of the sample conveyor 6 is moved to the belt conveyor 8.
Slide one sample container 7 from the end to the U-shaped receiver 9. At this position, the sample chuck 4 at the tip of one arm 3a of the L-shaped arm 3 descends as shown in FIG. Next, as shown in FIG. 2, the L-shaped arm 3 pivots, and the sample chuck 4 sets the sample container 7 on the holder 24 of the bomb 1 (see FIG. 4).

When the sample chuck 4 is located above the bomb 1 in this manner, the ignition wire chuck 5 at the tip of the other arm 3b of the L-shaped arm 3 is moved from the ignition wire supply device 13 to the ignition wire 12 as described above. Is pulled out, cut and chucked. Then, the L-shaped arm 3 turns to the position shown in FIG. 1 again, and the ignition wire chuck 5 sets the ignition wire 12 to the electrode 14 of the bomb 1. Thereafter, the L-shaped arm 3 stops at the intermediate position between FIG. 1 and FIG. 2, and the bomb 1 is calorimetrically measured by an automatic calorimeter.

After the measurement, the bomb 1 returns to the original position. Then, the L-shaped arm 3 moves to the position shown in FIG. 2, chucks the empty sample container 7, and drops the empty sample container 7 into the empty container inlet 25. This completes one cycle,
Hereinafter, the same cycle is repeated.

[0015]

As described above, according to the apparatus for supplying a sample and an ignition wire to the calorific value measuring apparatus of the present invention, the sample container and the ignition wire can be automatically supplied to the bomb. The calorific value measurement can be performed completely unattended.
In addition, since the chucks are provided at both ends of the L-shaped arm, it is possible to supply the sample container and the ignition wire without using a large-scale robot.
