Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention moves a long work in a vertical and longitudinal direction along a carrier rail erected above a plurality of surface treatment tanks, and moves it above a predetermined surface treatment tank. The present invention relates to a carrier that can raise and lower a long work.

[0002]

2. Description of the Related Art For example, an apparatus shown in FIG. 3 has been conventionally used as an apparatus for conveying a work which is an object of surface treatment and raising or lowering it. In FIG. 2, above a plurality of aligned processing tanks 1 and 1, a carrier rail 2 on which a carrier 3 for conveying a work 6 moves is installed. The carrier 3 is composed of a vehicle body provided with a pair of front and rear wheels, and a moving motor 35, a lift truck lifting motor 36, and the like are mounted on the upper surface thereof. An elevating guide 31 is hung from the vehicle body of the carrier 3, and an elevating carriage 32 provided with a hanger suspension portion 33 extending laterally is provided on the elevating guide 31 so as to be able to elevate. And, in the hanger suspension portion 33,
The hanger 4 to which the work 6 is attached is suspended. The work 6 attached in this way is conveyed together with the hanger 4 to the upper side of the desired processing tank 1 by the carrier 3, and the elevator carriage 32 is lowered there to lower the work 6 so that the work 6 is removed from the processing tank 1. A desired surface treatment can be performed by immersing in a treatment liquid.

However, when it is necessary to surface-treat a tip of a long work,
The work itself is attached to a hanger 4 as shown in FIG. 4 for processing. That is, the hanger body 4 provided by being suspended from the hanger receiving portion 40 provided with the hanger pin 41.
If the work 6 is properly attached to the frame body 5 with the longitudinal direction being up and down, and the hanger pin 41 is engaged with the hanger suspending portion 33 extending from the side of the lifting carriage 32 and suspended,
The surface treatment of the tip of the long work 6 can be performed in the same manner as in the above case.

However, in such a case, the long work 6
Is transported in a state of being suspended in the longitudinal direction below the carrier 3, so that it is inevitable that the distance between the processing tank 1 and the carrier rail 2 is increased by the length of the long work 6. Therefore, the carrier rail 2 must be installed at a high position, and by extension,
There was a problem that the height of the factory building that houses the processing system had to be increased.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and is capable of moving a long work in a vertical direction while suspending the carrier rail. The purpose of the present invention is to provide a carrier that does not need to be installed higher than usual.

[0006]

The above-mentioned problem is a carrier that moves on two parallel carrier rails, and is provided along the carrier rail from both sides of the body of the vehicle body. It consists of a pair of left and right elongated body parts equipped with wheels at the tip, and an elevating carriage is attached to the elevating guide fixed to the body of the body so that it can be raised and lowered. A hanger suspension part for suspending the attached hanger is arranged so as to be able to move up and down inside a recess formed by the pair of elongated body parts and the body part. It can be solved by a work carrier.

[0007]

Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. First, FIG. 1 is a plan view of a long work carrier according to an embodiment, and FIG. 2 is a side view of the same including a processing tank 1. Here, above the plurality of processing tanks 1 and 1, two parallel carrier rails 2 and 2 on which a transport carrier 3 for transporting the work 6 moves are installed. The carrier 3 is the body 3
b and a pair of left and right elongated vehicle body portions 3a, 3a extending along the carrier rail 2 from both sides of the vehicle body 3b and provided with wheels 34, 34 at their tip portions. further,
An elevating guide 31 is provided in the up-down direction on the vehicle body 3b, and an elevating carriage 32 having a hanger suspension portion 33 protruding horizontally is provided on the elevating guide 31 so as to be able to elevate. At the same time, the hanger suspension portion 33 has a recess 3 formed on a plane from the vehicle body 3b and a pair of elongated vehicle portions 3a, 3a extending from both sides thereof.
It is arranged so that it can move up and down inside 0.

That is, the hanger suspension portion 33 of the present invention is a portion that can be raised and lowered as a part of the lifting carriage 32, and is configured so as not to interfere with the structural portion of the carrier 3 when performing the raising and lowering operation. Of.
Therefore, by engaging the hanger suspension portion 33 with the hanger pin 41 provided on the hanger receiving portion 40 on the hanger side,
The hanger receiving portion 40, the hanger body 45, and the work 6 attached to the hanger can be hung while the longitudinal direction thereof is vertically changed as shown in FIG. 2 and one end of the work 6 is projected above the carrier rail 2. You can do it.

The work 6 attached in this manner is transferred to the desired processing tank 1 by the carrier 3 together with the hanger 4.
The workpiece 6 is conveyed to the upper side of the workpiece, and the elevator truck 32 is lowered there to lower the workpiece 6, so that the front end portion of the workpiece 6 can be immersed in the treatment liquid in the treatment tank 1 to perform a desired surface treatment. According to the transport carrier 3, the hanger suspension portion 33 has the recess 30 as described above.
Since it is arranged so as to be able to move up and down inside the container, there is no component that interferes with the long work 6 on one side of the recess and in the vertical direction. There is also an advantage that loading and unloading work can be easily performed.

[0010]

As described in the above embodiment, in the present invention, the hanger suspension part for suspending the hanger to which the long work is attached is located inside the concave portion where there is no component that interferes with the long work. Since it can be raised and lowered, it can be hung while the long work is set up and down in the longitudinal direction and one end of the work is projected above the carrier rail by an appropriate length, and the work can be easily loaded or unloaded. Can be done. Further, since the suspending position of the long work in the recess corresponds to the position close to the center of gravity of the transport carrier, the load can be stably suspended without bias.

[0011]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it is not necessary to install a carrier rail at a higher position than usual in a carrier carrier for suspending and moving a long work, and a building can be constructed. There is an excellent effect that the equipment cost of the transport structure including the same can be suppressed as usual. Therefore, the present invention has an extremely great industrial value as a long work carrier that solves the conventional problems.
