Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transporting an engine on an engine transport line that follows, for example, an engine assembly line, an engine test line, and an engine shipping line.

The engine delivered to the test bench on the engine test line is equipped with various pipes, etc. on the test bench side in order to ignite the engine.
That is, it is necessary to connect various piping and various electrical wirings for supplying or circulating engine cooling water, fuel, oil, etc. If these various types of piping, etc. are connected directly to the engine, it is difficult to automate the connection work of these various types of piping. The various piping, etc. held at one end by this connecting member are connected to the specified positions of the engine before entering the engine test line, and on the test bench, various piping, etc. on the test bench side are automatically connected to the connecting member on the pallet. It was configured to connect to In other words, to transport engines on the engine test line, a pallet dedicated to the engine test line, which is equipped with connection members such as the various pipings, has been used. In this conventional method,
The engine supported on a general transport pallet is transferred to the special engine test line pallet before the test line, and after the engine test is completed, the engine is transferred again to the general transport pallet and transferred to the shipping line. It was necessary to send it to
Therefore, it is necessary to install means for transferring the engine before and after the engine test line, which poses problems such as increasing the cost of the entire equipment.

The present invention provides a method that can solve the above-mentioned problems, and one embodiment thereof will be described below with reference to the attached illustrative drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a conveyance pallet equipped with a support member 3 for supporting an engine 2, and holes 5a and 5b for positioning connecting members 4 such as piping are provided at appropriate locations around the pallet. It is provided. The connecting member 4 for piping, etc. is, for example, a connector 6 that holds one end of the engine cooling water circulation piping 6, 7 and the fuel circulation piping 8, 9, and communicates with these piping 6 to 9.
A to 9a are provided horizontally, and pins 10a and 10b are provided protruding from the lower side to fit into positioning holes 5a and 5b on the pallet 1 side. Connectors 6b to 9b are attached to the free ends of each of the pipings 6 to 9, and are detachable from the piping connection portion on the engine 2 side.

Instead of providing the positioning holes 5a and 5b directly on the pallet 1, as shown in FIG.
It can also be installed horizontally on a bracket 11 that is erected from the ground. In this case, the positioning hole 5a,
The pins 10a and 10b that fit into the bracket 11 and the pallet 1 will be provided protrudingly.
Since the connecting member 4 comes into contact with the surface, it is also possible to have one positioning hole and one pin. Especially the 4th
When using the bracket 11 as shown in the figure, when the end connector 12a of the piping 12 on the test bench side is fitted and pressed into the corresponding connectors 6a to 9a on the connecting member 4, as shown by the imaginary line in FIG. , the pushing force can be received by the bracket 11, and there is no need to apply unreasonable force to the pins 10a, 10b that fit into the positioning holes 5a, 5b.

In addition, pins 10 for positioning holes 5a and 5b
If there is a risk that the connecting member 4 may come off unexpectedly or shake unduly by simply fitting a and 10b, a means for fixing the connecting member 4 to the pallet 1 may also be used. The fixing means in this case is preferably, for example, a conventionally known magnetic suction fixing means, which can be switched between a fixed state and a fixed release state with a single touch. Furthermore, a fixing means that can be switched between the fixed state and the fixed release state with a single touch can be incorporated into the pin.

The method of the present invention using the pallet 1 and the connecting member 4 as described above will be explained based on FIG.
13 is an engine assembly line, 16 is a turntable-type engine test device that constitutes a circular engine test line 14 following the engine assembly line 13, and 15 is the engine test line 14.
These are the shipping lines following 13.
As shown in FIG. Then, as shown in FIG. 3, the connecting member 4 is attached to the pallet 1, and the free end connectors 6b to 9b of the pipes 6 to 9, one end of which is held by the connecting member 4, are connected to predetermined locations of the engine 2. The work will be done. Thereafter, the engine 2 is placed on the test bench 16a of the engine test device 16 while being supported by the pallet 1.
The piping 1 on the test bench 16a side
The two end connectors 12a are connected to the corresponding connectors 6a to 9a on the connection member 4 side by an automatic connection mechanism.

The engine 2 on the engine test device 16 is operated with ignition as in the past, and a predetermined test is performed. At a work place 18 set in the
The connecting member 4 is removed from the holder. Thereafter, the engine 2 is transported to the shipping line 15 while being supported by the pallet 1.

In addition, in the embodiment, cooling water and fuel circulation piping 6
Although one connecting member 4 that holds one end of the pipes 9 to 9 has been illustrated, various other connecting members for piping and electric wiring can be used in the same way. Also, it is possible to have one connecting member hold the connectors for all the piping and wiring, or conversely, it is also possible to use a plurality of independent connecting members for each piping and wiring. Furthermore, in the embodiment, the engine transport line before the engine test line 14 was used as the engine assembly line 13;
It may be a mere engine transport line where parts are not assembled to the engine, or it may be a storage line for waiting time before entering the test line.

The method of the present invention can be carried out in the same manner as in the above embodiments, in which connecting members such as piping that hold one end of various piping used during engine testing are attached and detached from a fixed position on the pallet for supporting and transporting the engine. In the conveyance line before the engine test line, the engine is supported and conveyed by the pallet with the connecting members such as piping removed, and when this pallet reaches just before the engine test line, The piping, etc. connecting member is set in a fixed position on the pallet, and the other end of the piping, etc. held by the connecting member is connected to a predetermined position of the engine, and after the engine test is completed, the piping, etc. connecting member is set in a fixed position on the pallet. Since this method is characterized in that the engine is supported and transported by the same pallet in a state in which the engine is removed from the pallet, according to the method of the present invention, between the engine transport line before and after the engine test line and the engine test line, It is no longer necessary to transfer the engine between the transport pallet and the engine test line dedicated pallet as in the past, and the engine can be transported on the transport line including the engine test line while the engine is supported on the same pallet. At the same time, we were able to conduct the necessary engine tests.

As described above, according to the method of the present invention, there is no need for a special pallet for the engine test line, and there is no need for engine transfer means, so it is possible to significantly reduce the cost of the entire equipment, and the pallet This also eliminates the time loss associated with engine transfers and the risk of accidents due to transfer errors.

Note that, as shown in FIG. 5, a layout in which the connection member attachment/detachment work areas 17 and 18 are adjacent to each other is advantageous because a means for conveying the connection member 4 that holds one end of the pipe or the like is not required.
