Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a vertically suspended surface treatment apparatus, in which a large number of long materials are horizontally attached to or removed from a carrier bar, and the long materials are hung vertically on the carrier bar. The receiver relates to a table used for passing between the upper transport means and the transport means.

Generally, in order to mass-produce surface treatment of aluminum shapes used for building materials, etc., a large number of long materials are held on a carrier bar with a jig, and the carrier bar is suspended by a transportation means such as a crane or a conveyor. It moves between tanks and performs surface treatments such as pretreatment, anodizing, and painting.

The vertical hanging method is seen as promising because it is superior to the horizontal hanging method in terms of liquid drainage in the treatment tank and uniformity of the coating film during the dip coating process.

By the way, in vertically suspended surface treatment, it is necessary to attach a large number of long materials to a carrier bar before treatment, lift the carrier bar to hang it vertically, and deliver the carrier bar to a conveying means. After processing, on the contrary, it is necessary to receive the carrier bar suspending the long material from the conveyance means, place the long material in a horizontal state, and remove the long material from the carrier bar.
In particular, the work of attaching or removing a large number of long materials to or from a carrier bar, and the work of transferring a long material attached or an empty carrier bar to a conveyance means,
The vertical suspension method has not yet been put into practical use because no device has been devised that can perform this with high efficiency and safety.

This invention has been made in view of the above points, and in particular, it is possible to quickly carry a large number of long materials to a carrier bar, carry them to a position, attach them, or carry them out from a detached position. A table that can safely move a long material attached to a carrier bar from the installation position to the position where it is handed over to the conveyance means in a vertically suspended state, or from the position where it is picked up while vertically suspended from the conveyance means to the position where it is removed. The purpose of the present invention is to improve the production efficiency of surface treatment using a vertical hanging method.

Next, embodiments of the invention will be described based on the drawings.

As shown in FIG. 1, the table A according to the present invention has a frame 6 formed by framing a vertical frame 6a and a horizontal frame 6b in a rectangular shape.
The frame 6 is connected to the frame 6 via a conveyor 10 that is provided on the upper surface of the frame 6 and rotated by a motor fixed to the frame, and a rotating shaft 5 that is provided approximately at the center of the frame 6.
It is comprised of driving means 7, 8 and 9 for rotating and reciprocating between a horizontal state and a vertical state.

Table A is used by being installed on the floor at each of the material attachment and material removal positions of the surface treatment equipment.

In other words, as shown in Fig. 2, the material is installed on both the left and right sides near the front end (if the material is installed on the side) or the rear end (in the case of the material removal side) of the recess 2 provided in the floor 1 at the position or material removal position. Bearings 3 and 4 are provided protruding from the floor 1 on the outside, and a rotary shaft 5 perpendicular to the vertical frame provided approximately at the longitudinal center of the vertical frame 6a of the frame 6 is rotatably supported on the bearings 3.4. ing.

A gear 7 fixed to the rotary shaft 5 is meshed with a gear 9 fixed to a motor 8 fixed to the floor, so that the drive means consisting of the motor 8, gears 9, 7, etc. can drive the table. A can be rotated from a horizontal position shown by a solid line in FIG. 2 to a vertical position shown by a chain line, and can also be rotated in the opposite direction by reversing the motor.

Note that a fluid pressure cylinder or other known means may be used as the table driving means.

The conveyor 10 includes a plurality of bearings 1 protruding from each vertical frame 6a.
Rotating shafts 13, 14 are rotatably supported in parallel to 1..., 12..., and a plurality of conveyor belts are attached to the booths IJ 15, 16,... of each village fixed on each rotating shaft. 17 is stretched, and a motor 18 fixed to the frame 6 and one rotating shaft 14 are connected by a transmission belt 19 or the like, and each belt 17 is arranged parallel to the horizontal frame 6b of the frame. It extends from the outside of one vertical frame to the outside of the other vertical frame, and is driven by the motor 18 along a common plane.

In the horizontal state of the table, this conveyor 10 constitutes a material placement surface when attaching or removing a long material to or from a carrier bar, which will be described later.

Therefore, the height of the rotary shaft 5 from the floor is set so that when the table A is in a horizontal state, the top surface of the conveyor 10 is at a height suitable for manual attachment and removal of materials.

At one end of each vertical frame 6a of the frame 6, there is a carrier bar support portion 20 that removably supports the carrier bar B.
is provided.

The carrier bar support part 20 holds the carrier bar B without falling off when the table is in a horizontal state, and when the table is in a vertical state, the carrier bar support part 20 holds the carrier bar B without dropping it, and when the table is in a vertical state, the carrier bar support part 20 does not transfer the carrier bar B to the upper carrier bar conveying means described later. It is set up so that it can be done.

For this purpose, in the illustrated example, the vertical frame 6 of the frame
The carrier bar support portion 20 is formed by having one end portion of a protrude obliquely upward, and having a square groove opened in the horizontal direction (when the table is in a horizontal state) at the tip thereof.

The carrier bar B has a cross-sectional shape that prevents its rotation when it is fitted into the carrier bar support part 20, and a conductor 22 is fixed to it via a mounting piece 21, and a hook 23 is attached to the conductor. A large number of jigs 24 are arranged at required intervals for gripping a long material to be processed through the jigs 24.

The effect based on the above configuration will be explained.

First, to explain the effect of the table installed in the material mounting position, after the carrier bar B is fitted and supported on the carrier bar support part 20, the conveyor 10 is rotated at a constant speed, and the material made of the conveyor belt is Materials are carried in by placing long materials one by one on the loading surface in a direction perpendicular to the conveyor belt near the front end of the conveyor belt.

This material loading can also be done manually.

In that case, for example, two people can hold both ends of each long material from a freight car brought close to one of the vertical frames of table A, and place each material on a rotating conveyor one by one. They can be arranged in parallel with an interval approximately equal to that of the jigs.

Further, for carrying in materials, a carrying-in conveyor (not shown) having the same structure as the conveyor 10 is installed parallel to the conveyor 10 adjacent to one vertical frame side of the table A, and a large number of materials are placed on the carrying-in conveyor in advance. The long materials are placed at intervals equal to the jig spacing of the carrier bars, and the carrying conveyor and the conveyor 10 on the chifur are rotated at the same speed, so that the first long material is the carrier bar supported on the table. By stopping both conveyors when they reach the position corresponding to the frontmost jig, the material can be placed on the table automatically.

In any case, since the conveyor 10 is provided on the table, a large number of long materials can be sequentially placed on the table and moved to the position corresponding to each jig on the carrier bar. Aligning and placing the length materials on the table and attaching them to the carrier bar can be done easily and quickly.

When all the elongated materials have been attached to the carrier bar, the driving means 8 is driven to rotate the table from a horizontal position to a vertical position.

Thereby, the long material rotates while being placed on the conveyor and is automatically suspended vertically as the carrier bar 8 is lifted.

Therefore, the long material is suspended vertically without unnecessary swinging, so there is no risk of damage due to material collision or falling off from the jig.

Next, the lifted carrier bar B is lifted by a crane or a conveying means such as the illustrated lift conveyor 25, conveyed above the processing tank 21, and is sequentially lowered and raised while vertically suspended. Surface treated.

The carrier bar B that has undergone surface treatment is lowered by the lift conveyor 25 at the material removal position, and is placed on the carrier of another table that is waiting in the same vertical position as the above-mentioned table A installed at the same position. It is received by the bar support part 20.

The table is rotated from a vertical position to a horizontal position, and the processed material is manually removed from the jig.

Then, by rotating the conveyor on the table in the opposite direction or the same direction as when carrying in the material, the processed material is transferred from the material placement surface onto the connected conveyor,
Or transport it onto a transport vehicle.

After removing the surface-treated material, the empty carrier bar is transported by a crane or the empty carrier bar transport conveyor 26 to the position where the material is to be installed, and then returned to the lift conveyor 25 and lowered, where it stands in a vertical position. The carrier bar support portion 20 of the table A is fitted into the carrier bar support portion 20 of the table A.

The table is returned to the horizontal position and the previously described operation is repeated from the beginning.

As explained above, according to the present invention, the following effects can be obtained.

First, the material placement surface of the table is made up of a conveyor that can be driven by a motor, so when this table is installed in the material mounting position, the conveyor does not have to be driven. By placing long materials on the next conveyor, it is possible to easily carry in a large number of long materials on the material placement surface in a state where they are aligned with each jig of the carrier bar at equal intervals, and each Since long materials can be gripped by corresponding jigs, work efficiency in material attachment is significantly improved.

Further, if this table is installed and used at the material removal position, the processed materials removed from the carrier bar can be sequentially and quickly carried out from the table by driving the conveyor.

Secondly, when attaching or removing materials, the table can be held horizontally and the material can be placed on the material placement surface while being attached to or removed from the carrier bar. Even with heavy materials, work can be done easily and efficiently, with very little fatigue.

Thirdly, this table can be rotated and reciprocated between a horizontal state and a vertical state in which the carrier bar support part is upward by the driving means, and the carrier bar is detachable from the carrier bar support part. When the material is installed in the position, the table can be rotated from the horizontal position to the vertical position after the material is installed on the carrier bar, and the long material in the horizontal position can be quickly and safely vertically suspended. At the same time, the carrier bar can be transferred to the upper transport means.

In addition, when this table is installed in the material removal position, the carrier bar that vertically suspends the long material after surface treatment is removed from the carrier bar support part of the table in the vertical position, and then By rotating the material to a horizontal position, a vertically suspended long material can be quickly and safely brought to a horizontal position.
