BACKGROUND OF THE INVENTION The present invention relates to an alumite process in which a material to be surface-treated such as an aluminum mold material is hung on a transfer frame. The present invention relates to improvement of a suspension device.

[0002]

2. Description of the Related Art As a conventional suspension apparatus of this kind, for example,
There is one shown in Japanese Utility Model Publication No. 58-29177. Although not specifically shown, the conventional hanging device is provided with a J-shaped receiving bracket on the transport frame side, and has a T-shaped supporting bracket oscillatingly supported by the hanging jig on the hanging jig side. Assuming that a supporting metal fitting is provided, for the former metal fitting, the lower end is bent upward, and a single slit with an entrance side opened at the bent lower end is formed, and the latter is formed. With respect to the support fitting, a neck engaged in the slit of the receiving fitting and a pair of shoulders engaged with both side walls of the slit are formed, and the neck is connected to the hanging jig. ing.

Therefore, under such a conventional suspending device, the upper portions of the receiving fittings are individually fixed at fixed intervals to a transport frame, and the hanging jigs are inserted into the slits of the receiving fittings. By engaging the shoulders of the support fittings on both side walls of the slit while engaging the neck of the support fittings provided in series, the hanging jigs are spaced apart on the transport frame side by this. Since it can be set, it is only necessary to hold the upper end portion of the surface-treated material with each of the hanging jigs and transport the material on a predetermined processing line in a vertically suspended state.

In addition, when transferring on a predetermined processing line, each surface-treated material vibrates in the front-rear direction corresponding to the moving direction of the transfer frame in conjunction with the movement of the transfer frame. With respect to the vibration in the front-rear direction, a state in which the slit of the shoulder portion of the support fitting is locked to both side walls is obtained, and the neck portion of the support fitting vibrates in the same direction in the slit of the receiving fitting, so that the material to be treated is Vibration can be absorbed, so that the hanging jig can be opened by the leverage principle, preventing the material to be treated from falling and damaging the opening of the hanging jig. There is.

[0005]

However, in the vertical suspension type surface treatment step, the surface treatment is terminated even when the surface treatment material is attached to the hanging jig in order to perform the surface treatment. Even when removing the surface-treated material from the hanging jig, usually, once the transport frame is laid down together with the hanging jig, as is clear from the "Aluminum Surface Technology Handbook" issued by Light Metal Publishing Co., Ltd. It is performed by pushing down the operating lever of each hanging jig with a switchgear by turning it over to the state, especially when the transfer frame moves on a linear processing line. The transfer frame is set so that the falling direction of the transport frame is reversed between when the processing material is attached and when the processing material is removed.

Therefore, in such a situation, it is now assumed that the lower end of the bent of the receiving bracket is turned upward at the time of attachment and the lower end of the bent of the receiving bracket is turned down at the time of removal. When the suspension device is operated, when mounting, the depth of the slit is adjusted, and the neck of the support bracket is brought into contact with the end edge of the slit, so that the suspension jig can be kept in a flat posture. Because it can be regulated, it does not hinder the pressing of the operating lever of the hanging jig by the switchgear. The hanging jig that holds the surface-treated material is not aligned in a horizontal position, so the hanging jig inadvertently interferes with the switchgear and its frame, Supports operation lever pressing by switchgear Fear of causing a has had enough. Note that the same can be said for the case where the mounting and removing directions are reversed.

[0007] In the conventional suspension apparatus, the opening of the entrance side of the slit has an advantage that the supporting bracket can be easily supported by the receiving bracket, but on the other hand, the surface to be treated is provided in each processing tank. When immersing or lifting the material, if the material to be surface treated accidentally hits the processing tank and is pushed upward, the neck of the support bracket will easily come off the slit of the receiving bracket together with the shoulder, and There was also a risk that the treated material would fall. In addition, when the surface-treated material falls into the processing tank, the entire processing line must be temporarily stopped and the dropped surface-treated material must be collected, so that the processing efficiency is significantly reduced.

[0008]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional suspension apparatus. A supporting portion having a neck portion that engages in the slit and a pair of shoulder portions that are engaged with both side walls of the slit. Due to the function of the bent receiving portion, on the premise of a suspending device for the surface-treated material that vibrates the surface-treated material on the transport frame, the opening position of the slit is restricted to a sideways posture of the hanging jig. A configuration is adopted in which the obstruction is closed by an obstruction provided with a restricting means.

Therefore, in the present invention, even if the bent receiving portion faces downward when the transport frame falls down, that is, even if the opening entrance side of the slit faces downward, the neck portion of the support portion opens the slit. Since the suspension jig can be uniformly regulated by contacting the restricting means of the closing body closing the entrance side, it does not hinder the pressing of the operation lever of the suspension jig by the opening / closing device. . Also, even when the material to be treated is immersed in the treatment tank or pulled up, the material to be treated is accidentally bumped upward by hitting the treatment tank.
Due to the presence of the closing body, the neck of the support portion never falls off the slit of the bent receiving portion, so that it is possible to effectively prevent the surface-treated material from falling due to the push-up.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a suspension apparatus according to a preferred embodiment of the present invention. A supporting metal fitting is provided, and a supporting metal fitting serving as a supporting part is provided on the hanging jig side, and the supporting metal fitting is supported by the receiving fitting so as to be able to vibrate. The point is that the configuration is adopted.

First, as shown in FIG. 1, unlike the conventional case, the receiving bracket 1 is formed as a wide body having a fixed width by a copper plate, and its lower end is continuously bent in a substantially V-shape. The entrance 2 at a fixed interval at the lower end of the bend.
A plurality of slits 2 each having an open side a are formed with a desired depth, and an insertion hole 4 for a bolt 16 for fixing a closing body, which will be described later, is formed in a folded wall 3 defined between the slits 2. It has a configuration.

As shown in FIG. 2, a plate-shaped neck 7 engaged in each of the slits 2 is integrally connected to a hanging jig 10 as shown in FIG. A pair of cylindrical shoulders 8 are slidably engaged with both side walls of the slit 2 from the inside on both sides of the upper part, and a pair of outer sides abut against both sides of the slit 2 on both sides of the lower part. The guide roller 9 is rotatably provided.
The suspension jig 10 for connecting the support fittings 6 is not limited to the one shown in the drawing, but at least a clamping claw 11 for clamping the upper end of the material to be treated through spring pressure. Operating lever 1 for opening and closing the holding claws 11
2 is assumed.

Therefore, also in the present embodiment, the neck 7 of the support fitting 6 is individually engaged in each of the slits 2 of the fitting 1, and a pair of shoulders 8 are provided on both side walls of the corresponding slit 2. Is locked, the supporting bracket 6 is supported by the receiving bracket 1 together with the hanging jig 10 at a predetermined interval so as to be able to vibrate.

In this embodiment, on the premise of such a configuration, a closing member 13 for closing the open entrance 2a side of each slit 2 is mounted on the receiving fitting 1 side. Then, as shown in FIG.
It is formed as a thin plate body having a size corresponding to the width dimension of the receiving fitting 1 by a stainless steel plate, and the lower end portion 13a is bent outward at a certain inclination angle to form the lower end portion 1a.
3a is used as a restricting means for restricting the hanging jig 10 from lying down, and an insertion hole 14 for a bolt 16 corresponding to the insertion hole 4 on the receiving bracket 1 side is formed on the upper side.

However, in the present embodiment, the receiving bracket 1 and the closing body 13 are not completely coincident with each other and are mounted on the same width in such a manner that the positions thereof are shifted left and right by half of the folded wall 3. The insertion holes 14 formed at both ends are semicircular in shape, but all the insertion holes 14 may be perfectly circular by completely matching the width dimensions. It is optional depending on the implementation. Further, the straight lower end edge can be used as it is as the above-mentioned regulating means without bending the lower end portion 13a of the closing body 13.

Therefore, in the suspension device according to the present embodiment, as shown in FIG. 3, the receiving bracket 1 is attached to a mounting piece 15a which is continuously provided on the lower surface of the transfer frame 15. Using the upper mounting hole 5, the transfer frame 15 is sequentially fixed in the longitudinal direction, and the neck 7 of the support bracket 6 is engaged in each slit 2 of the receiving bracket 1. By using the insertion hole 4 of the receiving fitting 1 and the closing body 13 is fixed to the folded wall 3 of the receiving fitting 1 via the bolt 16 and the nut 17, the opening 2a side of each slit 2 is continuously connected. At the same time, the respective support fittings 6 are supported by the receiving fittings 1 together with the corresponding hanging jigs 10 so as to be able to vibrate without fear of coming off.

In this case, in the present embodiment, as described above, the receiving metal fitting 1 and the closing body 13 do not completely match in the width dimension, but only half of the folded wall 3. Because of the adoption of a configuration in which the mounting member is shifted left and right, the closing body 13 is fixed to the adjacent receiving brackets 1 with the crotch by the amount of the shift described above.

In the actual operation, when the surface treatment material W is to be attached, the bent lower end of the receiving bracket 1 faces upward, and when the workpiece W is removed, the bent lower end of the receiving bracket 1 faces downward. Assuming the case, at the time of attaching the surface-treated material W, as in the related art, as shown in FIG. 4, the abutment of the neck 7 of the support fitting 6 with the end edge 2 b of each slit 2 causes the hanging jig 10 Even if a large number of hanging jigs 10 are set in the transport frame 15, it is possible to control the operating levers 12 of the hanging jigs 10 by a switch (not shown) because the horizontal posture can be uniformly regulated. There is no hindrance to the pressing F.

When removing the surface-treated material W,
For example, even if the bent lower end of the receiving bracket 1 faces downward, that is, the opening 2a side of the slit 2 faces downward, as shown in FIG.
Abuts on the lower end portion 13a bent at a certain inclination angle, and also the horizontal posture of the hanging jig 10 can be uniformly regulated, so that the hanging jig 10 Does not hinder the pressing F of the operating lever 12.

Therefore, according to the present embodiment, as in the prior art, the neck 7 of the support bracket 6 freely swings in the slit 2 in which the entrance 2a is opened during the overturning process of the transport frame 15, thereby causing a fall. The hanging jig 10 holding the surface treatment material W is not aligned in a sideways posture, and the hanging jig 10 inadvertently interferes with the opening / closing device and its gantry. This can effectively prevent troubles. still,
It is needless to say that the same effect can be expected even when the transport frame 15 is turned upside down during mounting and removal.

When the transport frame 15 is erected and transported on a predetermined processing line, the material W to be treated also coincides with the moving direction of the transport frame 15 in conjunction with the movement of the transport frame 15. However, even in the present embodiment, as shown in FIG. 6, as shown in FIG. Since the neck 7 vibrates in the same direction in the slit 2 of the receiving fitting 1 and can absorb the vibration of the surface treatment material W, the hanging jig 10 is opened and the surface treatment material W Can be prevented from being dropped and the holding claws 11 of the hanging jig 10 can be prevented from being damaged. The vibration of the support fitting 6 is smoothly promoted by the guide roller 9.

Since the vibration of the surface-treated material W is allowed within the range between the terminal edge 2b of the slit 2 and the lower end 13a of the closing body 13, the relationship with the above-described regulation of the sideways posture will be described. In addition, the depth of the slit 2 and the inclination angle of the lower end 13a of the closing body 13 are freely determined.

When the material W to be treated is immersed or pulled up into each of the treatment tanks (not shown), even if the material W to be treated hits the treatment tank and is pushed upward, the slits are formed. Since the neck 7 of the support fitting 6 does not come off from the slit 2 of the receiving fitting 1 together with the shoulder 8 due to the presence of the closing body 13 that closes the opening 2a of the base 2 as in the prior art, Due to the falling of the material W, there is no need to stop the entire processing line once and collect the dropped surface-treated material W. Accordingly, this can also eliminate the concern that the processing efficiency is reduced.

In the above-described embodiment, the receiving fitting 1 is formed as a wide body, and a plurality of slits 2 are perforated in the receiving fitting 1 of the wide body. However, the present invention is not limited to this.
It is also possible to directly apply the configuration of the receiving fitting 1 to the mounting piece 15a or the like of No. 5. In addition, the support jig 6 can be formed separately from the suspension jig 10 without being connected to the suspension jig 10 and connected to the suspension jig 10 later. The shape of the shoulder portion 8 of 6 is not limited to a cylindrical shape, but may be a flat plate shape or another different shape.

[0025]

As described above, according to the present invention, the adoption of the above structure allows the neck portion of the support portion to be connected to the opening entrance side of the slit even if the bent receiving portion is downward when the transport frame is overturned. Since it is possible to uniformly regulate the sideways posture of the suspension jig by contacting the regulating means of the closing body to be closed,
The operation of the operating lever of the suspension jig by the opening and closing device does not hinder the operation.

Further, even when the material to be treated is immersed or pulled up into the treatment tank, even if the material to be treated accidentally collides with the treatment tank and is pushed up, the closing body for closing the open entrance side of the slit is not required. Since the neck portion of the support portion never comes off the slit of the bent receiving portion due to the presence, the fall of the surface-treated material due to the push-up can be effectively prevented.
