Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to the process from removing tubes from packaging to heat exchangers (
It is used in the technical field of automatic insertion of U-bend tubes for atomic steam turbine auxiliary equipment, high-low water feed water heaters, moisture separation heaters, etc. (functions with U-bend tubes).

Conventional heat exchangers use various types of tubes made of materials with good heat transfer as the lifeblood of heat transfer. 31) is used (mainly due to heat transfer performance, copper-based tubes are used, so they are easily deformed).

In order to insert U-pend tubes into heat exchangers, the tubes are received from the tube manufacturer, are unpacked, and then the tubes are transported and inserted to the heat exchanger to be inserted, as shown in Figure 3, which traditionally involves the manual work of many people. It was done.

For this reason, the tube may be deformed due to handling during installation from the box, transportation, or insertion, and there is a possibility that the performance and value of the product may not be guaranteed.

Problems to be Solved by the Invention The present invention eliminates the unstable work caused by manual handling as described above, and at the same time solves problems such as deformation of the U tube during insertion. , U
The pendotube automatic insertion system and insertion force setting detection function can be quantified.

Means to solve the problem: A tube lifting and transporting device that has a tube lifting function, a tube U diameter adjustment function, a lifting blade span function, and a tube transport function, a tube receiving function, a tube U diameter adjustment function, and a receiving blade span adjustment. Function, 90 degree rotation function and number of inserted tubes classification are functions Tube receiver rotation classification is device, traverse trolley, tube guide support device with tube droop correction function, tube guide support device, tube, tube pushing device and tube R receiver It consists of a tube insertion device and a tube insertion device.

According to the means described above, a series of repeated automatic operations are performed from unpacking tubes as received to completing insertion of all tubes up to the time of vertically inserting the tubes.

Embodiment Next, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

The automatic insertion device of the present invention includes a tube lifting and conveying device 1.
(Fig. 1), tube holder rotation section is device 2 (Fig. 1)
and a tube insertion device 3 (FIG. 1).

The tube lifting and transporting device 1 has a tube lifting function (id, 1u), a tube U diameter adjustment function (IC), a lifting blade span adjustment function (1d), and a tube transporting function (1e).

The tube holder rotation section is device 2, which has a tube holder function (
2a), tube U diameter adjustment function (2b), receiving blade span adjustment function (2c), 90 degree rotation function (2d), and insertion tube number classification function (2e).

It consists of three tube insertion devices, a traversing cart 4, a tube guide support device 5 with a tube sagging correction function, a tube guide support device 6, a tube pushing device 7, and a tube R receiving device 8.

The traversing cart has a 4-tube receiving function 4a and a tube arrangement movement function 4b.

5 tube guide supports with tube sagging correction function,
Tube droop correction function 5a, tube U diameter adjustment function 5b
, and a support evacuation function 5C.

Tube guide support 6 has tube U diameter adjustment function 6
a. It has a support evacuation function 6b.

The tube pushing device 7 includes a pushing portion 7a1 consisting of several pushing rods, a pushing portion U diameter adjustment function 7b, a pushing device driving traveling cart 7c1 a pushing force setting detection function 7d, a tube R receiving function 7e, and a tube R receiving retracting function 7f. have.

A U-tube placed horizontally in a box is adjusted to its U diameter using the U-diameter adjustment function 1c of the tube lifting and transporting device 1 (Fig. 2, 11), and lifted (Fig. 2, 1).
2) The tube receiving rotating section is not transported to the device 2.
Fig. 13), hanging (Fig. 2, 14).

The tube receiving rotation section has two devices, and before receiving the tube, the U diameter adjustment function 2b is used to adjust the U diameter (Fig. 2 15).
), hanging and set tubes can be rotated 90 degrees 2
a (FIG. 2, 16), and the section is transferred by function to the tube guide support of the receiving tube insertion device 3 (FIG. 2, 17).

The tube transferred to the tube guide support on the traversing cart 4 is adjusted to the U diameter of the tube by the push rod of the tube pushing device 7, and then the tube R receiving guide support of the pushing device 7 is set, and the tube is The tube is inserted onto the traversing carriage 4 with the tube being supported by the tube insertion device 3 (FIG. 2, 18).

5 tube guide supports with tube sagging correction function,
In order to correct the amount of tube sag so that the tube can be correctly inserted into the product's tubing system, the support is moved and corrected by the tube sag correction function 5a (FIG. 2, 19).

This correction function is canceled when a tube is inserted into the 8-tube system.

As the tube is pushed in, the tube guide supports are sequentially retracted (FIG. 2, 20), and finally the tube R receiving portion of the pushing device is retracted, completing the insertion.

The above operation is repeated until all the tubes are inserted.
Each time the operation is repeated, the tube arrangement movement function 4b of the traversing trolley 4 works, and the tubes are inserted in the correct arrangement (second
Figure, 21). Also, during insertion, is the pushing force setting detection function of the pushing device 7? The pushing force is detected by dK and controlled in the limiting pushing direction to prevent tube deformation.

Note that these series of operations and effects are controlled by a microcomputer.

Effects of the Invention According to the device of the present invention, a tube package received from a tube manufacturer (packaged horizontally) is unpacked as it is, and the tubes are inserted vertically until all tubes are inserted. This can be done through repeated automatic operations.

However, by mechanizing this device, the unstable work caused by manual handling can be eliminated and the tube deformation that could occur with conventional manual insertion can be resolved.

Furthermore, a one-limit pushing force is set and the pushing force is constantly controlled so as not to exceed the pushing force during insertion, thereby preventing tube deformation due to the generation of excessive pushing force as in the case of manual insertion.
