Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deflection compensating mechanism for a carrier guide that is installed on columns at both ends to move a carrier.

[0002]

[Prior art]

 For example, when performing a process of dipping a work in several tanks such as cleaning / etching or plating, there is a carrier as a means for moving the work contained in a basket or the like from tank to tank. . The carrier moves along carrier guides installed on columns at both ends.

The carrier guide and the supporting column supporting the carrier guide are welded and integrated with each other. By having such a tough structure, the carrier guide and the carrier guide's own weight, etc. The conveyor guide was designed so that it would not easily bend.

[0004]

[Problems to be solved by the device]

 However, there is a limit to the weight that does not cause the conveyor guide to bend, and if the limit is exceeded, the conveyor guide will sag, causing the workpiece to move on each tank as the conveyor moves along the conveyor guide. The stop position of the basket containing a mark shifts downward. In particular, the deviation becomes large at the central position of the guide of the transporting machine.

As a countermeasure, conventionally, a height adjusting tool attached to the lower part of the column has been used to adjust the height of the column to raise the stop position of the basket containing the work. With the method, since the height of the entire carrier guide is changed and the deflection remains as it is, there is a problem that the stop position of the basket by the carrier varies up and down in each part of the carrier guide.

The present invention is to provide a deflection correction mechanism for a transport guide, which is capable of correcting the deflection of the transport guide itself due to the weight of the transport and the weight of the transport guide itself.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the invention according to claim 1 is a deflection correcting mechanism of a carrier guide which is installed on columns at both ends to move the carrier, and is a connecting portion between the column and the carrier guide. In addition, the present invention is characterized in that a flexure correction mechanism for providing a warp in a direction for correcting the flexure of the guide is provided.

According to a second aspect of the present invention, in the first aspect of the present invention, a carrier guide mounting portion for mounting the carrier guide is provided on the support column, and the deflection correction mechanism described above is provided. The apparatus is characterized in that it is provided with a deflection correcting means that is externally adjustable and is attached to the supporting portion to correct the deflection of the guide of the transporting machine.

Further, in the invention according to claim 3, in the invention according to claim 2, the deflection correcting means is attached to the carrier guide mounting portion to vertically move the carrier guide. An adjustable fixing means for fixing the carrier guide in a state in which the warp can be given, and a deflection compensation screw member for pushing up the lower surface of the carrier guide to give the warp to the carrier guide in the up and down directions. It features a configuration.

[0010]

[Action]

 According to the invention as set forth in claim 1, since the deflection itself of the conveyor guide can be corrected by the deflection correction mechanism at the connection portion between the support column and the conveyor guide, for example, the conveyor guide can be kept horizontal. Therefore, it is possible to prevent the vertical stop position of the basket containing the work and the like on each tank from being vertically displaced due to the movement of the carrier.

According to a second aspect of the present invention, there is provided flexure correction means fixed to the support column and movably assembled to a support portion on which the carrier guide is placed, for correcting the flexure of the carrier guide. Since the flexure correction mechanism is formed by operating the flexure correction means, the flexure itself can be corrected by deflecting the guide of the transport machine in the direction opposite to the flexure generated in the guide of the transport machine.

Further, according to the invention of claim 3, the carrier guide is fixed by the adjustable fixing means in a state where the warp can be given, and the lower surface of the carrier guide is pushed up by the screw member to convey the carrier guide. Deflection of the conveyor guide can be corrected by giving the guide an upward warp.

【Example】

 An embodiment of a deflection adjusting mechanism of a guide for a transporting machine according to the present invention will be described below with reference to FIGS. 1 to 5.

First, FIG. 1 shows an overall configuration of a carrier device as an example to which the present invention is applied. 1, 2, 3 are tanks, 4 is a floor surface, 5 is a pillar, 6 is a carrier guide, and 7 is a guide. Is a carrier, and 8 is a basket containing a work (not shown).

In the illustrated example, the transfer device is incorporated in equipment for performing a process of sequentially immersing a workpiece in three tanks 1, 2, 3 such as a cleaning tank, such as cleaning / etching and plating. The carrier 7 is movably assembled to the carrier guides 6 that are installed on the left and right columns 5 and 5 standing on the floor 4.

A basket 8 containing a work is suspended and supported by the transport device 7 so as to be vertically movable. When the transport device 7 is moved along the transport guide 6, the basket 8 is suspended and supported by the transport device 7. A predetermined process can be performed by sequentially immersing the work contained in the basket 8 in three tanks 1, 2, and 3 such as a cleaning tank while the vertical movement of 8 is performed.

On the left and right struts 5 and 5 of this carrying device, the bending correction mechanism 50 of the carrying machine guide according to the present invention is provided.

FIG. 2 is an enlarged view showing a supporting portion of a support column which constitutes the deflection correcting mechanism 50 of the conveyor guide according to the present invention. In the upper part of the support column 5 made of a metal square pipe, the same metal is used. A plate-shaped carrier guide mounting table 52 is fixed by welding or the like.

The central portion of the carrier guide mounting table 52 is a flat surface on which the carrier guide 6 is placed, and both side portions thereof are inclined pieces 52a and 52a which are slanted downward. . Screw holes 52b and 52b are formed in the inclined pieces 52a and 52a, respectively.

As shown in FIG. 3, correction bolts 54 and 55 as deflection correction screw members are screwed into the screw holes 52b and 52b, respectively.

Further, as shown in FIG. 2, a plate-shaped carrier guide mounting portion 56 made of the same metal is erected by welding or the like on the upper rear side end of the carrier guide mounting base 52 of the support column 5. There is.

The carrier guide mounting portion 56 has mounting holes 56a, 56a, 56a, 56a formed by so-called stupid holes at four corners of its vertical surface.

As shown in FIG. 2, mounting bolts 57 for fixing the carrier guide 6 to the carrier guide mounting portion 56 are respectively inserted into the mounting holes 56a in a playable state, and the tips thereof are shown in FIG. As shown, it is screwed into the screw hole 62 in the side wall of the carrier guide 6. The carrier guide 6 is fixed to the carrier guide mounting portion 56 while adjusting the carrier guide 6 in a state where the four mounting bolts 57 and the four mounting holes 56a can give a vertical warp to the carrier guide mounting table 52. The adjustable fixing means 60 is obtained.

Next, the left supporting column 5 shown in FIG. 2 shows how to set the deflection of the carrier guide 6 by using the deflection correcting mechanism 50 of the carrier guide according to the present invention configured as described above. The deflection adjusting mechanism 50 for the upper transport guide will be described.

Since the deflection adjusting mechanism 50 of the conveyor guide on the right support 5 is symmetrical to the left one, it can be operated in a completely symmetrical manner with the left one. The description of the operation for correcting the deflection of the guide for the transport machine is omitted.

In order to preliminarily correct the possible deflection of the transport guide 6, the four mounting bolts 57 of the deflection correcting mechanism 50 are first loosened and the four mounting bolts 57 descend in the mounting hole 56a. After making the state, tighten only one mounting bolt 57 at the lower left.

In this state, the correction bolt 54 on the left side is loosened to retract the tip side thereof, while the correction bolt 55 on the right side is tightened to project the tip side, and the carrier guide 6 is predicted at the tip. When pushed up from the lower surface side to such an extent that the obtained deflection can be eliminated, the conveyor guide 6 rotates counterclockwise around the lower left mounting bolt 57 as an axis, and the middle portion thereof bends upward. Then, in that state, the other three bolts 57 are also tightly tightened. Further, the correction bolt 54 on the left side is also tightened so that the tip of the correction bolt 54 is in contact with the lower surface of the conveyor guide 6.

The deflection adjusting mechanism of the guide of the conveyor on the right column 5 also performs a symmetrical operation according to this in parallel.

By setting in this way, the warp in the opposite direction is given by the amount of deflection expected due to the self-weight of the transport device 7 and the transport device guide 6, and the deflection of the transport device guide 6 is corrected. Therefore, unlike the conventional one that does not use the deflection correction mechanism 50 of the carrier guide, the stop position of the basket containing the work on each tank due to the movement of the carrier 7 along the carrier guide 6 is lowered. You don't have to slip.

On the contrary, when it is desired to correct the warp (upward warp) in the reverse direction of the conveyor guide 6, loosen the four mounting bolts 57 of the deflection correction mechanism 50 shown in FIG. After the four mounting bolts 57 are lowered in the mounting hole 56a, only one mounting bolt 57 at the lower right is tightened.

In this state, the correction bolt 55 on the right side in FIG. 2 is loosened, while the correction bolt 54 on the left side is tightened to push up the conveyor guide 6 from its lower surface side to the extent that the sled is returned by the tip. Then, the transporter guide 6 is rotated clockwise around the mounting bolt 57 at the lower right as an axis to reduce upward warpage of the intermediate portion. In this state, tighten the other three mounting bolts 57.

With respect to the carrier guide on the right column 5, the symmetrical operation according to this is also performed in parallel.

By setting in this way, it is possible to correct the excess warp of the transporting machine guide 6 above and to correct it.

In the above embodiment, one of the four correction bolts 57 is used as a shaft center to rotate the end of the guide 6 of the conveyor to correct the deflection of the guide 6 of the conveyor. However, the present invention is not limited to this, and, for example, a portion of the conveyor guide 6 located in the middle of the four correction bolts 57 shown in FIG. (Not shown) may be rotated about the axis.

With this configuration, the deflection can be adjusted more easily.

According to a second aspect of the present invention, there is provided flexure correction means fixed to the support column and movably assembled to a support portion on which the carrier guide is placed, for correcting the flexure of the carrier guide. Since the flexure correction mechanism is formed by operating the flexure correction means, the flexure itself can be corrected by deflecting the guide of the transport machine in the direction opposite to the flexure generated in the guide of the transport machine.

Further, according to the invention of claim 3, the carrier guide is fixed by the adjustable fixing means in a state where the warp can be given, and the lower surface of the carrier guide is pushed up by the screw member to lift the carrier guide.
