The present invention relates to a clamp bar jig for making an object movable.

Conventionally, in order to perform uniform coating on cosmetic containers, exterior bodies of mobile phones, etc., a rotatable spindle is continuously provided on a moving means passing near the painting means, and a holder is placed above the spindle. In addition, a method is used in which a workpiece is attached to the holder, and a coating process is performed while rotating the spindle.
For example, Patent Document 1 discloses a method of performing a coating process while rotating a spindle as a method of performing multicolor coating on an exterior body of a mobile phone.
More specifically, as shown in FIG. 21, the holder 305 is fixed to the exterior body 310 of the mobile phone after the first color paint is applied above the spindle 304 that is continuously provided on the conveyor line 303. It is attached to. Next, after placing the masking die 311 for the second color coating on the exterior body 310 of the mobile phone, the second color is carried by the spray nozzle 302 of the spray gun coating apparatus while rotating the spindle 304 described above. The surface of the telephone 310 is sprayed and painted.
Such a coating method is used in many fields because it can continuously and uniformly apply a large number of objects to be processed and the productivity is very high.
Then, as a method of rotating the spindle moving in the horizontal direction by the moving means, a method of rotating the spindle by bringing the forced rotation member into contact with the moving spindle, or by providing a rotation motor on the spindle itself. A method of rotating is performed. Among these rotation methods, since the configuration is easy and it is suitable for processing a large amount of objects to be processed, there is a wide range of methods for rotating the forced rotation member in contact with the moving spindle. It has been adopted.

However, when using a method in which a forcible rotating member is brought into contact with the moving spindle and rotated, the processed objects must be removed from the spindle one by one and moved to the next process. The problem was seen. That is, there has been a problem that the production efficiency of the product is remarkably lowered at the stage of moving the processed object after the treatment to the next process, for example, the vapor deposition process.
In view of this, a so-called long object-integrated spindle is used in which the structure of the spindle is simplified and reduced in weight, and a plurality of such spindles are arranged so as to be rotatable with respect to a long object.
In other words, with this type of spindle, a plurality of processed objects to be processed can be easily removed from the moving means together with the long object while the processed objects are still mounted on the spindle. This is because the processed product can be moved to the next step.

2. Usage Mode (1) Spinning Spindle The driving spindle to which the clamping rod jig of the present invention is applied is, as shown in FIG. 2 (a), a moving means 150 included in a workpiece conveying apparatus (not shown). On the other hand, it means the spindle 110 that is rotatably fixed and moving in the horizontal direction (A).
Such a spindle is a jig having excellent rotational stability for rotating an object to be processed, for example, a cosmetic bottle, etc., and is applied to the object to be processed by rotating the object to be processed. It is a jig for carrying out processing and drying processing uniformly.
The spindle and the workpiece transfer apparatus will be described in detail in the second embodiment and the third embodiment, respectively.
Needless to say, the clamping rod jig of the present invention can be applied to a spindle that is not driven.

(2) Object to be processed including the holder The object to be processed including the holder to be removed from the driving spindle by the clamping rod jig of the present invention is shown in FIG. As shown to a), the to-be-processed object 157 of the state mounted with respect to the holder 156 is meant.
The holder 156 is configured to be detachably mounted on the spindle 110. By replacing only the holder 156, the holder 156 can handle various types of workpieces 157, and the spindle The workpiece 157 can be stably placed on the 110.
In addition, when the workpiece to be processed including the holder is removed from the driving spindle, the holder part is removed from the spindle. It becomes possible to move to the process.
In addition, as a to-be-processed object in the state including the holder, a to-be-processed object in a state where the holder is removed later falls within this category in a broad sense.

(3) Mounting of Clamp Bar Jig As a usage mode of the clamp bar jig of the present invention, in order to simultaneously remove a plurality of workpieces including a holder from a driving spindle, first, FIG. As shown in b), the clamping rod jig 10 of the present invention is attached to the workpiece 157 including the holder 156.
That is, as shown in FIG. 3, the clamp 20 of the clamping rod jig 10 is pressed against the holder 156 portion of the workpiece 157 including the holder 156 with a predetermined force. 20 is attached to the holder 156.

Accordingly, after a plurality of objects to be processed including the holder are removed at the same time, the plurality of objects to be processed are efficiently moved to the next process such as a vapor deposition process, for example. be able to.

3. Long Object (1) Shape As shown in FIG. 1, the long object 30 is shaped like a bar.
This is because the handleability of the clamping rod jig can be improved by making the shape of the long object a rod.
That is, if the shape of the long object is a rod, the clamp bar jig can be easily held by hand, so that the work including mounting to the workpiece including the above-described holder and subsequent removal from the spindle are performed. This is because it can be performed quickly and accurately.
In addition, such a simple shape can contribute to easy and inexpensive production of a clamp bar jig.
The cross-sectional shape of the long object is not particularly limited, and various shapes such as a square, a rectangle, and a circle can be selected as appropriate.

(2) Size Moreover, it is preferable to make the length of a long thing into the value within the range of 20-200 cm.
The reason for this is that when the length of such a long object becomes a value of less than 20 cm, the number of objects that can be removed from the driving spindle at the same time is excessively reduced, which may reduce the production efficiency of the product. Because there is. On the other hand, when the length of the long object exceeds 200 cm, the handleability of the clamp bar jig may be excessively lowered.
Therefore, the length of the long object is more preferably set to a value within the range of 50 to 150 cm, and further preferably set to a value within the range of 80 to 120 cm.
In addition, the diameter in the cross section of a long thing will not be restrict | limited especially if it is a range which can hold | maintain sufficient intensity | strength and does not hinder handling property, However, It is set as the value within the range of 5-50 mm. It is preferable that the value be within a range of 10 to 30 mm.

(3) Material The material of the long object is not particularly limited as long as it has a predetermined strength, but the next step includes, for example, a step involving heating such as a vapor deposition step. In such a case, predetermined heat resistance is also required.
Therefore, metals such as aluminum, steel, stainless steel, brass, and copper are preferably used. Among them, aluminum is a particularly preferable material because it can contribute to weight reduction of the clamp jig and is excellent in workability.

4). Clamp (1) Basic Configuration The clamp according to the present invention can be securely attached to the holder portion of the workpiece including the holder by pressing with a predetermined force, and used repeatedly. Even if it is a case, as long as it has the characteristic that composition deformation is difficult, it will not be restrict | limited.
As such a clamp, as shown in FIGS. 4A to 4D, an L-shaped fixture 21 for an elongated object, an L-shaped leaf spring material 22, and the leaf spring material cooperate with each other. It is preferable that the clamp 20 has a workpiece holding portion 23 for holding the workpiece including the holder in pressure contact with the L-shaped fixture 21.
Moreover, as shown in FIG.4 (d), with respect to a long thing, the edge part of the L-shaped fixing tool 21 and the edge part of the L-shaped leaf | plate spring material 22 are the same fixing tools 40a and 40b. In addition, it is preferable that the workpiece holder 23 is fixed to the L-shaped leaf spring material 22.
The reason for this is that by configuring the clamp with such three members, a plurality of objects to be processed including the holder can be simultaneously obtained regardless of the size of the object to be processed including the holder. This is because it can be easily clamped and removed from the spindle. Moreover, it is because it can prevent effectively that a clamp carries out plastic deformation by comprising in this way.
That is, when the clamp is attached to the holder portion of the object to be processed including the holder, the L-shaped fixture and the object holding portion, which are members that directly sandwich the holder part, Each L-shaped leaf spring material for imparting elastic force is prepared separately, and fixed to a long object so as to have a predetermined configuration, so that each member has effective characteristics. This is because it can be exhibited.
Furthermore, it is possible to easily assemble the clamp and replace it when it is damaged.
In addition, as a fixture for fixing the edge part of an L-shaped fixing tool and the edge part of an L-shaped leaf | plate spring material with respect to a long thing, it is preferable to use a screw and a nut, for example.
Moreover, as a method of fixing the workpiece holding portion to the L-shaped leaf spring material, for example, it is preferable to perform spot welding.

(2) L-shaped fixture (2) -1 shape As shown in FIG. 4A, the shape of the L-shaped fixture 21 is a shape in which a plate-like member is bent in a generally L-shape. It only has to be.
The reason for this is that if it is such an L-shaped shape, it effectively cooperates with the workpiece holding part 23 fixed to the L-shaped spring member 22 so that the holder part can be sandwiched reliably and easily. This is because it can.
In addition, such a simple shape can contribute to easy and inexpensive production of a clamp bar jig.
In addition, as shown to Fig.4 (a), by bending the upper end part of the L-shaped fixing tool 21 outside, a holder part can be pinched more reliably and easily.

(2) -2 Size The height (m1) of the L-shaped fixture is preferably set to a value within the range of 10 to 150 mm, for example, and the horizontal length (m2) of the L-shaped fixture. ) Is preferably set to a value within a range of 10 to 100 mm, for example.
Moreover, it is preferable to make the width | variety of an L-shaped fixture into the value within the range of 5-50 mm, and to make thickness (m3) in an L-shaped fixture into the value within the range of 0.5-3 mm. preferable.
The reason for this is that by setting the size of the L-shaped fixture in such a range, the holder part can be securely and easily sandwiched while maintaining the handleability as a whole of the clamping rod jig. This is because the character member, and thus the entire clamp, can be stably fixed to the long object.

(2) -3 Material The material of the L-shaped fixture is not particularly limited as long as it has a predetermined strength. For example, the next step involves heating such as a vapor deposition step. When the process is included, predetermined heat resistance is also required.
Accordingly, examples of a material that can be suitably used include metals such as S steel, stainless steel, aluminum, brass, and copper, and thermosetting resins and photocurable resins such as epoxy resins, acrylic resins, and polyesters. On the other hand, since the L-shaped fixture and the workpiece holding portion described later are members that directly sandwich the holder portion, the deformation of the member immediately leads to instability of the sandwiching.
Therefore, it is more preferable to use S steel that is particularly high in hardness and hardly deforms.

(3) L-shaped leaf spring material (3) -1 shape As shown in FIG. 4 (b), the shape of the L-shaped leaf spring material 22 is a shape obtained by bending a plate-like member into a generally L-shape. It only has to be.
The reason for this is that the L-shaped spring material 22 and the L-shaped spring material 22 are placed on the L-shaped fixture 21 as shown in FIG. This is because the fixed object holder 23 can be easily overlapped without any gap.
And as shown in FIG.4 (d), predetermined | prescribed mobility can be provided with respect to the to-be-processed object holding | maintenance part 23, although it is a simple structure by superimposing each of these members. Because.
The spring material may be configured other than the L-shaped leaf spring. Examples of such a spring material include a conventionally known spring material such as a spring.

(3) -2 Size The height (n1) of the L-shaped leaf spring material is preferably set to a value within the range of 5 to 80 mm, for example, and the lateral length of the L-shaped leaf spring material. (N2) is preferably set to a value in the range of 10 to 100 mm, for example.
The width of the L-shaped leaf spring material is preferably set to a value within the range of 5 to 50 mm, and the thickness (n3) of the L-shaped leaf spring material is set to a value within the range of 0.1 to 3 mm. It is preferable.
This is because the mobility of the workpiece holder can be easily adjusted by setting the size of the L-shaped leaf spring material within such a range.
Therefore, the force with which the clamp sandwiches the holder portion can be easily adjusted.

(3) -3 Material In addition, as a material of the L-shaped spring plate material, a material capable of imparting a predetermined mobility to the workpiece holding portion, that is, exhibiting a predetermined elastic force. The material is not particularly limited as long as it is a material that can be used. However, when the next step includes a step involving heating, such as a vapor deposition step, a predetermined heat resistance is also required.
Therefore, as a material suitably used, stainless steel (SW-C (80C), SWP-A, SWP-B, SWOCV-V, SWOSC-V, SWOSC-B, SUP-10, SUS304WPB, SUS316WPA, SUS304, SUS316 And the like.
In particular, even when used repeatedly, it is more preferable to use SUS304 which is a kind of stainless steel because the excellent elastic force can be maintained.

(4) Shape to be processed holding part (4) -1 shape As shown in FIG. 4C, the shape of the object to be processed holding part 23 is not particularly limited, but at least to introduce the holder portion. The outer curved portion 23a and the holding portion 23b for sandwiching and holding the holder portion are preferably provided.
Therefore, it is preferable that the cross-sectional shape of the contact surface of the workpiece holding portion with the workpiece including the holder is a wavy shape.
The reason for this is that, by making the cross-sectional shape of the contact surface corrugated, a plurality of objects to be processed including the holder can be simultaneously obtained regardless of the size of the object to be processed including the holder. This is because it can be easily clamped and removed from the spindle.
That is, if the cross-sectional shape of the nodal surface is corrugated, it is possible to obtain the workpiece holding portion having the above-described outer curved portion and holding portion in spite of the simple configuration. is there.
In addition, when the cross-sectional shape in the to-be-processed object holding | maintenance part 23 is made into a wave shape, the angle ((theta) 1) for forming the outer curved part 23a shall be a value within the range of 90-150 degrees, for example. The angles (θ2 and θ3) for forming the holding portion 23b are preferably set to values within the range of 90 to 150 °, for example.

(4) -2 Size The height (o1) of the workpiece holder is preferably set to a value within the range of 10 to 150 mm, for example, and the width of the workpiece holder is, for example, 5 It is preferable to set it as the value within the range of -50 mm, and it is preferable to set the thickness (o2) of the to-be-processed object holding | maintenance part to the value within the range of 0.5-3 mm, for example.
The reason for this is that by setting the size of the workpiece holding portion within such a range, it becomes easy to form the predetermined outer curved portion and the holding portion, so that the holder portion can be easily sandwiched and fixed. This is because it can be easily removed thereafter.

(4) -3 Material The material of the workpiece holder is not particularly limited as long as it has a predetermined strength, but basically, the material of the L-shaped fixture described above. And can be similar.

(5) Other aspects In addition, the aspect of the clamp in this invention is not limited to what was shown in FIG.
For example, as shown in FIGS. 5A to 5C, an L-shaped fixture 21 ′, an L-shaped leaf spring material 22 ′, and a workpiece holding portion 23 ′, FIG. The clamp 20 ′ of another mode as shown in FIG. 9 may be configured, and various other modes can be adopted.

(6) Arrangement Further, as the arrangement of the clamps on the long object described above, a plurality of clamps 20 are arranged on the same side of the long object 30 as shown in FIG. It is preferable to protrude in the short direction.
The reason for this is that by arranging the clamps in this way, the clamp bar jig can be more easily and accurately applied to the plurality of spindles connected to the moving means of the workpiece transfer apparatus. Because.
In addition, it is also preferable to provide a location for changing the arrangement of the clamp in advance for the long object.
More specifically, it is preferable to previously provide a screw hole or the like that is used when the arrangement of the clamp is changed.
The reason for this is that by providing a location for changing the arrangement of the clamps in advance, even if the interval between the spindles to be applied is changed, the distance between the spindles can be adjusted according to the interval between the spindles. This is because the arrangement of the clamps can be corrected.

As another arrangement, for example, as shown in FIG. 6, it is also preferable that a plurality of clamps 20 are arranged on both sides of the long object 30.
The reason for this is that if the distance between the clamps arranged on both sides is the same distance as shown in FIG. 6 (a), the workpiece to be processed is doubled by one clamp bar jig. This is because it can be removed from the spindle and moved.
In addition, if the distance between the clamps arranged on both sides is different as shown in FIG. 6B, it is possible to easily cope with the change in the distance between the spindles with one clamp bar jig. This is because it can be done.

5). Positioning member Further, when the clamp jig according to the present invention is configured, the end of the long object is in contact with the object to be processed including the holder in the driving spindle and includes the holder. It is preferable to have a positioning member for guiding the object to be processed to a predetermined place of the clamp.
The reason for this is that by providing such a positioning member, the positioning between the workpiece including the holder and the clamp can be easily and accurately even though the spindle is driven. It is because it can do.
That is, in order to apply the clamp rod jig to the driving spindle, as a previous step, an operation of accurately facing the respective clamps to the corresponding driving spindle, that is, positioning is performed. There is a need to.
On the other hand, the positioning efficiency of the clamp rod jig is determined by the position of the spindle located at the head of the driven spindle to which the clamp rod jig is applied and the clamp disposed at the end of the long object. It depends on the efficiency of the texture.
Therefore, by providing a positioning member at the end of the long object, the positioning of the clamp disposed at the end of the long object, and hence the positioning of the entire clamp bar jig, can be easily and accurately performed. be able to.

More specifically, as shown in FIG. 1, the end 30a of the long object 30 to be applied to the spindle located at the head of the driving spindles to which the clamping rod jig 10 is to be applied. It is preferable to make the positioning member 50 by setting the height of the L-shaped fixture in the clamp 20a arranged at the position higher than the height of the L-shaped fixture in the other clamps.
The reason for this is that, by adopting a configuration in which the positioning member is integrated with the L-shaped fixture, the clamping rod jig positioned by the positioning member is pressed against the spindle being driven as it is, This is because a plurality of clamps can be easily attached to the holder on each spindle.
Furthermore, because of the simple configuration, it can be easily manufactured as a variation of the L-shaped fixture.
In addition, it is preferable that the positioning member is configured by extending the height of a normal L-shaped fixture by a value within a range of 10 to 200 mm, for example. Moreover, the width | variety and thickness can be made the same as that of an L-shaped fixing tool. Further, the material can be the same as that of the L-shaped fixture.

It is also preferable to configure the positioning member as a positioning member 50 'as shown in FIG.
The reason for this is that, as shown in FIG. 7, if the positioning member includes the vertical positioning portion 50a ', not only the longitudinal direction of the clamping rod jig but also the vertical positioning is easy. This is because it can contribute to performing accurately.
However, in order to apply such a positioning member 50 ', as shown in FIG. 8A, a holder 156 having a convex portion 156a with which the vertical positioning portion 50a' abuts, or FIG. As shown in b), it is necessary to use a removal assisting member 156b as a part of the holder 156.

[Second Embodiment]
Next, as a second embodiment, a spindle to which the clamping rod jig according to the first embodiment is applied will be specifically described.
That is, as shown in FIGS. 9 and 10, the first bearings 132 and 134 and the second bearings 116, 119, and 136 are provided as a plurality of bearings, and are mounted on the moving means 150 and moved in the horizontal direction. In addition, the spindle 110 is rotatable by contact with a forced rotation member of the forced rotation device, and includes the following members (a) to (c).
(A) A rotation support member 110a that is rotatably mounted on a rotation shaft 139 fixed to the moving means 150 via first bearings 132 and 134.
(B) It has a contact surface 120b that comes into contact with the forced rotation member, and has second bearings 116, 119 (upper) and 136 (lower) above and below the contact surface 120b, respectively, and the rotation support member 110a. Contact drive member 110b fixed to
(C) A support bar member 110c for placing an object to be processed directly or via a holder, which is fixed to the contact drive member 110b.
That is, not only the first bearing but also the second bearings provided at two upper and lower portions can stably rotate or convey the object to be processed.
Therefore, not only a heavy object can be processed effectively, but also the clamping rod jig can be applied more stably to the driving spindle.
Hereinafter, the spindle according to the first embodiment of the present invention will be specifically described for each configuration requirement with reference to the drawings as appropriate.

1. Rotation Support Member As shown in FIGS. 9 and 10, the rotation support member 110 a is rotatably mounted on a rotation shaft 139 fixed to the moving means 150 via first bearings 132 and 134. .
This is because the rotating shaft is fixed to the moving means, and the rotating shaft and the rotation support member are in contact with each other via the first bearing. It is because it becomes easy to exhibit.
That is, with such a configuration, the rotating shaft directly fixed to the moving means does not operate even when the spindle is rotated. This is because the rotation of the spindle is not adversely affected.

Further, as shown in FIGS. 9 and 10, the rotation support member 110a is preferably fitted with a hole in the contact drive member 110b and fixed with a screw 120d or the like.
The reason for this is that the rotation mechanism composed of the rotation support member and the rotation shaft is covered from above by the contact drive member, so that even when a coating process or the like is performed, excellent rotation performance is exhibited. It is because it can do.
That is, since the workpiece placed on the spindle is positioned above the rotation support member, the paint or the like during the coating process falls from above the spindle. However, since the rotation mechanism is covered from above by the contact drive member, it is possible to effectively prevent the paint or the like from entering there.

Further, the first bearings 132 and 134 are not particularly limited as long as they can make the rotary shaft 139 and the rotation support member 110a contact with each other in a rotatable manner, but reduce the friction more. Therefore, it is preferable to use a ball bearing.
It should be noted that the diameter (outer diameter) of the first bearing depends on the size of the spindle and the like, but is generally preferably a value in the range of 20 to 30 mm.

As shown in FIGS. 9 and 10, the rotation support member 110 a includes a plurality of bearings 132 and 134 as first bearings, and contacts the rotation shaft 139 between the plurality of bearings 132 and 134. It is preferable to provide a boss member 133 that does not.
The reason for this is that by providing a plurality of contact points between the fixed rotating shaft and the first bearing, a predetermined interval can be provided between the plurality of first bearings, and as a result, more stable. This is because the spindle can be rotated.
That is, because there are a plurality of first bearings in the rotation support member and they are arranged at a predetermined interval, the rotation shaft and the spindle are more stably mounted. Therefore, even when a heavy object is placed as an object to be processed, it can be stably rotated and transported.
Moreover, since the force concerning a 1st bearing can be disperse | distributed effectively by comprising in this way, it can contribute also to the lifetime improvement of a spindle including a 1st bearing.
In addition, as a space | interval between 1st bearings, although a suitable range changes with the magnitude | sizes of a spindle etc., it is generally preferable that it is a value within the range of 10-100 mm, and within the range of 15-80 mm. It is more preferable that the value is.

Moreover, it is preferable to use brass as a material substance of the boss member 133.
The reason for this is that even if the rotation support member and the contact drive member are fitted together or separated by using brass having excellent smoothness and thermal conductivity as the material material of the boss member Even so, it is because excessive friction between the metal members can be prevented.
In addition, as shown in FIG. 9, it is preferable to make the length (p3) of the rotation support member 110a into the value within the range of 50-100 mm, for example. Moreover, although it is an example, it is preferable to make the diameter into the value within the range of 20-30 mm.

2. Contact Driving Member As shown in FIGS. 9 and 10, the contact driving member 110b has a contact surface 120b that contacts a forced rotation member described later, and a second bearing 116 above and below the contact surface 120b. 119 (upper) and 136 (lower), respectively, and fixed to the rotation support member 110a.
The reason for having the contact surface for the forced rotation member in this way is to rotate the spindle by the frictional force generated when the side surface of the spindle and the forced rotation member are brought into contact with each other through the contact surface.
In addition, the reason why a plurality of bearings are provided as the second bearings at two locations above and below the contact surface is that the second bearing and the guide member provided on the side are in contact with each other so that it is stable. This is because the workpiece can be rotated and transported. In addition, by changing the arrangement of the guide members, even when a heavy object or the like is transported in a transport process including a process of forced rotation, the guide member can be transported stably.

The second bearings 116, 119 (upper) and 136 (lower) are not particularly limited as long as they can rotateably contact the guide member, but the friction is further reduced. Therefore, it is preferable to use a ball bearing.
The diameter (outer diameter) of the second bearing depends on the size of the spindle and the like, but it is generally preferable that the value be in the range of 25 to 40 mm.
As shown in FIG. 10, the contact drive member 110b and the rotation support member 110a are fixed by screws 120d or the like, so that the frictional force generated on the contact surface 120b of the contact drive member 110b is caused by the rotation support member 110a. Thus, the rotation is made around the rotation shaft 139.

Further, as shown in FIGS. 9 and 10, a plurality of bearings 116 and 119 are provided as second bearings above the contact surface 120b of the contact driving member 110b, and intervals between the plurality of bearings 116 and 119 are set. A value in the range of 5 to 50 mm is preferable.
This is because not only the stability of the spindle is improved by arranging the second bearing in this manner, but also paint or the like infiltrates between the second bearings when the coating process is performed. This is because even if it is cured, it can be easily washed to maintain the rotation function.
That is, by providing a plurality of second bearings above the contact surface of the contact driving member, the upper part of the spindle can be supported from both sides with respect to the traveling direction of the spindle, and the spindle is moved. This is because the second bearing can rotate. Therefore, even when a heavy object or the like is placed on the spindle, it can be transported sufficiently stably.

In addition, it is preferable that the interval between the plurality of second bearings 116 and 119 is a value within the range of 5 to 50 mm. With such an interval, the stability of the spindle is further improved, and This is because a predetermined detergency can be obtained.
Accordingly, the interval between the plurality of bearings 116 and 119 is more preferably set to a value within the range of 10 to 40 mm, and further preferably set to a value within the range of 15 to 30 mm.

Moreover, it is preferable that the material substance which comprises the contact surface 120b is an aluminum-type metal.
This is because the weight of the spindle can be easily adjusted within a suitable range in terms of stability and load on the moving means, and the workability can be improved.
That is, conventionally, since a material substance mainly composed of iron has been used as a material substance constituting such a contact surface, there has been a problem that the spindle is very heavy. For this reason, particularly when the traveling path of the spindle is curved, there is a case where the spindle is inclined and cannot be stably conveyed due to the centrifugal force generated in the spindle itself.
Also, a very large load is applied to the moving means on which the spindle is placed, and particularly fatigue of the pulley portion below the moving means and the rail member on which the pulley travels is significant.
Therefore, the use of a relatively light aluminum-based metal can solve such problems of conveyance stability and weight.
However, when pure aluminum is used as the aluminum-based metal, although it is excellent in lightness, mechanical strength and workability are poor, and on the contrary, there are cases where it cannot be stably conveyed.
Therefore, as described later, a predetermined amount of copper (Cu), silicon (Si), iron (Fe), manganese (Mn), chromium (Cr), zinc (Zn), titanium (Ti), etc. as an aluminum-based metal. It is preferable to use contained aluminum.

In addition, the aluminum-based metal is particularly preferably an aluminum-based metal containing 3 to 8% by weight of copper with respect to the total amount.
The reason for this is that by adding copper in the range of 3 to 8% by weight to aluminum, the hardness is remarkably improved (Brinell hardness (HB)> 100), and mechanical properties (tensile strength> 400 N / mm). ² and shear strength> 200 N / mm ² ) and workability (elongation 10-45%).
That is, when the copper content is less than 3% by weight, the effect of adding copper is not sufficiently exhibited, and the mechanical characteristics may not be sufficiently improved. This is because, for example, the Brinell hardness (HB) may be about 1/5, such as 20 or less. Further, the strength of 70N / mm ² or less tension, or becomes about 1/5, the shear strength of 50 N / mm ² or less, there are cases that may become about 1/4.
On the other hand, when the copper content exceeds 8% by weight, the hardness may become excessively high or blue rust may be easily generated.
Therefore, as an aluminum-type metal, it is more preferable to make content of copper with respect to whole quantity into the value within the range of 4-7 weight%, and it is further more preferable to set it as the value within the range of 5-6 weight%.

In addition, as shown in FIG. 9, it is preferable to make the length (p4) of the contact drive member 110b into the value within the range of 100-150 mm, for example.
Moreover, it is preferable that the length (p5) of the support rod member mounting portion 120a is, for example, in the range of 50 to 70 mm, and the diameter thereof is in the range of 5 to 30 mm.
Furthermore, the length (p6) of the contact surface 120b is preferably set to a value in the range of 25 to 40 mm, for example.

3. Support Bar Member As shown in FIGS. 9 and 10, the support bar member 110c is fixed to the above-described contact drive member 110b as a member for placing an object to be processed directly or via a holder.
This is because the distance between the object to be processed and a processing apparatus such as a spray gun can be within a suitable range by placing the object to be processed on the support rod member. . Moreover, it is because it can suppress that a coating material etc. adhere directly with respect to the contact drive member mentioned above and the moving means mentioned later by providing this support bar member.
More specifically, as shown in FIGS. 9 and 10, the support rod member 110c and the contact drive member 110b are fixed by screws 120c or the like, so that the rotation support member 110a and the contact drive member 110b described above are fixed. This is because the support rod member 110c can be rotated in conjunction with the rotation of.

Further, as a form of fixation between the contact drive member 110b and the support rod member 110c, the contact drive member 110b and the support rod member 110c are fitted and fixed, and the depth of the fit can be adjusted. Is preferred.
This is because the length of the support bar member can be changed without separately preparing a support bar member having a different length even when the workpiece transfer device, the processing means and the workpiece to be mounted are changed. This is because it can be adjusted.
That is, since it is not necessary to prepare a plurality of support bar members having different lengths, it is not only economically advantageous, but also the length of the support bar member can be easily changed.
More specifically, as shown in FIGS. 11A and 11B, a support bar member 110c ′ provided with a plurality of groove portions abutting against a screw 120c for fixing to the contact drive member at an arbitrary interval is used. Thus, the depth of fitting between the contact drive member and the support bar member can be easily adjusted.

Moreover, when performing a coating process etc., it is preferable to attach a cover member with respect to a support bar member.
The reason for this is to prevent the paint or the like from adhering directly to the support bar member.
That is, when paint or the like enters and hardens a fixed portion of the support rod member and the contact drive member, it becomes difficult to separate the support rod member and the contact drive member or to fix them again. This is because there are cases.
Therefore, for example, as shown in FIG. 12A, it is preferable to attach a cylindrical cover member 155 that can cover the entire support bar member 110c to the support bar member 110c. In addition, as shown in FIG.12 (b), after finishing a coating process etc., the cover member 155 can be removed and only the cover member 155 can be wash | cleaned.

Further, when placing the object to be processed on the support bar member via the holder, for example, as shown in FIG. 13A, the holder 156 for placing the object to be processed is attached to the spindle. It is preferable to attach it to.
That is, it is preferable that the holder 156 can be detachably attached to the upper portion of the support rod member 110c of the spindle 110.
This is because it is possible to deal with various types of objects to be processed by replacing only the holder.
Further, the holder preferably has a shape suitable for the shape of the object to be processed in order to stably place the object to be processed. For example, as shown in FIGS. 13B and 13C, it is preferable to provide a protrusion 156a or the like that matches the shape of the workpiece 157a.
As shown in FIG. 9, the length (p2) of the support bar member 110c is preferably set to a value in the range of 100 to 500 mm, for example.

In addition, the clamp can be easily and securely attached to the holder part, and the holder part can be easily and reliably removed from the spindle. It is preferable to attach a removal assisting member.
The reason for this is that by providing such a removal assisting member between the holder and the spindle, it is possible to easily provide a clamp location with respect to the holder, making it easier to position and mount the clamp jig. This is because it can be made accurate.
In addition, the holder portion can be easily detached from the spindle by adjusting the degree of fitting between the holder and the tip of the spindle.
More specifically, as shown in FIG. 8C, the removal assisting member 156b basically has a first fitting portion 156c for the spindle tip, a clamp location 156d, and a holder for fitting with the holder. It is preferable that the second fitting portion 156e having a wing spring is included.
Further, it is preferable that the clamp location 156d is a recess.
The reason for this is that the positioning by the positioning member can be made easier and more accurate and the holder part can be removed from the spindle more easily by configuring the clamping part to be a recess. is there.

4). Moving Means and Forced Rotating Means The spindle in the present invention is a spindle that is placed on the moving means, moves in the horizontal direction, and can be rotated by contact with the forced rotating means.
This is because the spindle is fixed to the moving means and moves in the horizontal direction.For example, a spray gun as a coating device, an infrared drying device as a drying device, etc. are arranged on the side of the traveling path of the spindle. This is because the desired treatment can be carried out continuously and stably.
Moreover, it is because a coating process, a drying process, etc. can be performed uniformly with respect to a to-be-processed object by rotating a spindle by a forced rotation means.
Note that these moving means and forced rotation means will be described in detail in the third embodiment.

[Third Embodiment]
Next, as a third embodiment, a workpiece transfer apparatus including a spindle to which the clamping rod jig according to the first embodiment is applied will be specifically described.
That is, as shown in FIGS. 9 and 10, the first bearings 132 and 134 and the second bearings 116, 119, and 136 are provided as a plurality of bearings, and are mounted on the moving means 150 and moved in the horizontal direction. In addition, the workpiece transfer device includes a spindle 110 that can rotate by contact with a forced rotation member of the forced rotation device, and includes a guide member that contacts the second bearing, and the spindle 110 includes: It is a to-be-processed object conveying apparatus provided with member (a)-(c).
(A) A rotation support member 110a that is rotatably mounted on a rotation shaft 139 fixed to the moving means 150 via first bearings 132 and 134.
(B) It has a contact surface 120b that comes into contact with the forced rotation member, and has second bearings 116, 119 (upper) and 136 (lower) above and below the contact surface 120b, respectively, and the rotation support member 110a. Contact drive member 110b fixed to
(C) A support bar member 110c for placing an object to be processed directly or via a holder, which is fixed to the contact drive member 110b.
That is, with this configuration, the rotational performance and stability of the spindle can be improved more effectively.
Further, even when the clamping rod jig is pressed against the driving spindle by the guide member with which a predetermined bearing abuts, the shake of the spindle can be suppressed.
Therefore, not only heavy objects can be processed more effectively, but also the clamp bar jig can be applied more stably to the driving spindle.
Hereinafter, the workpiece transfer apparatus according to the third embodiment will be specifically described with a focus on differences from the first and second embodiments.

1. Basic Configuration As shown in FIG. 14, a workpiece transfer apparatus 500 according to the present invention includes a specific spindle 110 described in the second embodiment, a moving unit 150 for moving the spindle 110, and a spindle 110. A forced rotation device 200 for rotating and guide members 160, 161, and 163 for contacting the second bearing in the spindle 110 are basically provided.
Therefore, the workpiece transfer apparatus according to the present invention includes a spindle provided with a plurality of second bearings at predetermined locations and a guide member that comes into contact with the plurality of bearings, so that the forced rotation member of the forced rotation device is brought into contact with the workpiece. Even if it is a case, a to-be-processed object can be rotated and conveyed stably.
Moreover, even if it is a case where a heavy article is conveyed in the conveyance process including the process of forcedly rotating, it can be conveyed stably. More specifically, spindle inclination and excessive vibration can be suppressed.
Furthermore, since the spindle is mounted in a form that covers the rotating shaft fixed to the moving means from above via the first bearing, the rotating shaft can be used even when a coating process or the like is performed. In addition, since the paint or the like does not enter the rotation mechanism including the first bearing, stable rotation can be effectively maintained.
Therefore, the processing object transport apparatus according to the present invention can stably and efficiently process the processing object even if the processing object is a heavy object or the like.
In FIG. 14, an arrow B indicates the traveling direction of the spindle 110, and an arrow C indicates the rotational direction of the spindle 110.

2. Forced Rotation Device As shown in FIG. 14, in the workpiece transfer apparatus 500 according to the present invention, a forced rotation having a forced rotation member for rotating the spindle 110 by contacting the moving spindle 110. A device 200 is provided.

(1) Rotating Belt Type Forced Rotating Device As shown in FIG. 15, the forced rotating device 200 used in the present invention is a rotating belt type forced rotating device provided with a belt member 171 that is rotated by a driving means as a forced rotating member. 200a is preferred.
This is because the forced rotation device can have a simple configuration by configuring in this way. Therefore, the spindle can be efficiently rotated even if the number of driving means is one.
In other words, since a belt having an arbitrary length can be rotated by a single driving means, it is easy to obtain a forced rotation device having a simple configuration and a scale as required.
In addition, since the forced rotation member is a belt member that is rotated by the driving means, the rotation speed of the spindle is arbitrarily adjusted by adjusting the rotation speed of the belt so that the rotation speed is suitable for the processing to be performed. Because it can.
In addition, the forced rotation apparatus of such a form is used suitably in the process process as which a rotational speed (100-400 rpm) more than predetermined is requested | required like a coating process.

Moreover, the structural example of the rotating belt type forced rotation apparatus 200a is demonstrated using FIG.
First, the rotating belt type forced rotating device 200a has a rotating roller 174 that is rotated by a driving means (not shown). And it has the belt member 71 which rotates with rotation of this rotation roller 174. As shown in FIG.
The material constituting the belt member 171 is not particularly limited as long as it has predetermined elasticity, wear resistance, heat resistance, and the like. , Urethane rubber, nitrile butadiene rubber, chloroprene rubber, EPDM rubber, silicone rubber, fluorine rubber and the like. In order to improve durability, mechanical strength, etc., it is also preferable to add carbon black, silica, titanium oxide, fiber, glass fiber, metal powder, cross-linking agent, etc. to these rubber materials.
Further, it is preferable that a plurality of pressing rollers 167 are provided for pressing the rotating belt member 171 in the direction of arrow D against the contact surface 120b of the spindle 110 by the spring 170.
Furthermore, it is preferable to have an adjusting member 172 for adjusting the distance between the entire rotating belt type forced rotating device 200a and the spindle 110.
The reason for this is that, with this configuration, the belt can be stably rotated, and the rotating belt can be pressed against the spindle without difficulty and with certainty.

(2) Fixed Forced Rotating Device Further, as another forced rotating device, a fixed forced rotating device 200b including an elastic body 164 fixed to a support member 166 as shown in FIG. 17 is also preferable.
This is because the forcible rotating member is an elastic body fixed to the support member at the side in the traveling direction of the spindle, so that a rotational force is generated simply by pressing the elastic body against the traveling spindle. is there. Accordingly, it is possible to rotate the spindle at a low speed, stably and silently without damaging the spindle with a simpler configuration without separately providing a driving means such as a motor.
That is, when the contact surface of the spindle that is moved by the moving means comes into contact with the elastic body fixed to the support member, a rotational force is generated and the spindle automatically rotates. The spindle can be rotated with a simple configuration. Further, by adjusting the moving speed of the spindle, the diameter of the contact driving member, the pressure contact force, and the like, the rotating speed of the spindle can be accurately adjusted within a range of, for example, 10 to 60 rpm. Furthermore, since the elastic body 164 is used as a rotational drive source, it can be rotated stably at low speed and silently without damaging the spindle, unlike contacting a metal plate or the like.
And the fixed type forced rotation apparatus of such a form is for drying the to-be-processed object (not shown) after a coating process, for example using the infrared rays drying apparatus 175 attached as shown in FIG. It is suitably used in the drying process.
The reason for this is that by rotating the workpiece after coating treatment relatively slowly, uniform and efficient heating can be performed on the whole, and the resulting coating film strength can be increased, This is because it can be stabilized. On the other hand, when rotating at an excessively high speed in the drying process, the predetermined centrifugal force acts, resulting in drying of only the surface, and the solvent tends to remain inside, resulting in uneven drying. It is.
In addition, as shown in FIG. 17, such a fixed forced rotation device uses an electrostatic removal device 176 provided thereto, and removes static electricity to prevent dust from adhering to the object to be processed before painting processing. It is also preferably used in the process.
This is because, when rotating at high speed in the static electricity removing step, the amount of charged particles reaching the object to be processed is reduced, and the static electricity removing effect may be significantly reduced.
In FIG. 9, the arrow B indicates the traveling direction of the spindle 110, and the arrow C indicates the rotational direction of the spindle 110.

In addition, a configuration example of the fixed forced rotation device 200b will be described in more detail with reference to FIG.
First, the shape of the elastic body 164 is preferably a plate shape as shown in the figure.
This is because it is easy to adjust the degree of pressure contact with the spindle 110 by changing the thickness and width of the plate.
The material of the elastic body 164 is not particularly limited as long as it has predetermined elasticity, wear resistance, heat resistance, and the like. Examples thereof include silicone rubber and fluororubber having heat resistance.
In addition, the support member 166 that fixes the elastic body 164 preferably has an angle (θ4) for pressing the elastic body 164 against the contact surface 120b from an oblique direction.
This is because the elastic body 164 is brought into a pressure contact from an oblique direction so that the elastic body 164 is gently curved during the pressure contact, and a force can be stably applied to the contact surface 120b.
In addition, it is preferable to make this angle ((theta) 4) into the value within the range of 30-70 degrees, for example.

3. Guide Member As shown in FIG. 14, the workpiece transfer apparatus 500 according to the present invention includes guide members 160, 161, and 163 that can rotatably contact the second bearing provided on the spindle 110. .
And this guide member can exhibit another effect in two processes shown below, respectively.

(1) Forced Rotation Step As shown in FIGS. 16 and 18, the guide members 160 and 163 are provided on the side opposite to the side where the forced rotation devices 200 a and 200 b are installed with respect to the traveling direction of the spindle 110. Is preferred.
This is because even when the forced rotation member is pressed against the contact surface, the spindle can be stably rotated and moved while effectively preventing the spindle from tilting.
That is, when the forcible rotating member comes into pressure contact, the spindle is pushed toward the side opposite to the side where the forcible rotating device is installed with respect to the moving direction of the spindle.
However, the plurality of second bearings provided above and below the contact surface of the spindle are in contact with the guide member provided on the side opposite to the side where the forcible rotation device is installed with respect to the traveling direction of the spindle. By touching, the pushed spindle can be rotatably supported.

Further, as shown in FIGS. 16 and 18, the guide members 160 and 163 are preferably fixed with respect to the side wall 160 a fixed to the workpiece transfer apparatus.
The material of the guide members 160 and 163 is not particularly limited as long as it has a predetermined strength, and metal, ceramic, resin, or the like can be used.
The length of the guide members 160 and 163 can be any length as long as it corresponds to the length of the forced rotation devices 200a and 200b, but for example, a value within the range of 10 to 1000 cm. Preferably there is.

(2) Conveying process including a forced rotation process As shown in FIG. 19, the second bearing provided above the contact surface 120b includes a plurality of bearings 116 and 119, and a plurality of bearings that abut each from one side. The guide members 160 and 161 are provided, and one of the guide members is the above-described guide member 160, and the other guide member 161 is provided with the above-described guide member in the traveling direction of the spindle. It is preferable to provide it on the opposite side to the other side.
This is because the upper part of the spindle can be supported from both sides with respect to the traveling direction of the spindle, and the second bearing can be rotated as the spindle moves. Therefore, even when a heavy object is placed on the spindle, it can be transported more stably.
That is, by supporting the upper part of the spindle from both sides with respect to the moving direction of the spindle, even when a heavy object is transported, it can be transported stably while preventing the spindle from shaking.

Further, it is preferable that the guide member abuts only on one side with respect to the moving direction of the spindle with respect to each second bearing.
This is because the second bearing rotates and the spindle can be smoothly moved by this configuration. On the other hand, when a guide member is brought into contact with one second bearing from both sides, each guide member exerts a force to reversely rotate the second bearing. This is because the rotation of the second bearing becomes difficult.
Note that the fixing method, material, length, and the like of the guide members 160 and 161 are the same as those in the guide member in the forced rotation process described above.

4). Moving means The workpiece transfer apparatus according to the present invention includes moving means having a rotating shaft for moving the spindle in the horizontal direction and rotatably mounting the spindle.
The moving means is not particularly limited as long as it can move the spindle in the horizontal direction and can stably fix the rotation shaft for rotatably mounting the spindle. Particularly preferably, it is preferable to use a conveyor chain 150 as shown in FIG.
This is because if the moving means is a conveyor chain, it is easy not only to fix the rotation axis of the spindle, but also to easily curve the traveling path of the spindle in an arbitrary direction.
That is, as shown in FIG. 10, it is easy to integrate the rotating shaft 139 of the spindle and the components 140 and 141 of the conveyor chain. In addition, this configuration is because it becomes easy to provide the rotation axis of the spindle perpendicular to the horizontal plane. Furthermore, as a result of such a configuration, it is easy for the conveyor chain and the spindle to exert their respective characteristics in a coordinated manner without restricting the functions of each other.

As shown in FIG. 20, it is preferable that a pulley 152 and rail members 162 and 162 ′ are provided below the moving means 150, and that the cross-sectional shape of the rail members 162 and 162 ′ is convex upward. .
This is because the stability of the spindle against the force applied from the side surface with respect to the traveling direction of the spindle can be further improved.
In other words, a pulley is provided at the lower part of the moving means, and the cross-sectional shape of the rail member for the pulley to travel is convex upward so that the spindle can be seen from the side in the direction of spindle movement. This is because even if this force is applied, it becomes difficult for the pulley to derail from the rail member.
As shown in FIG. 20 (a), the rail member has a cross-sectional shape such as a rail member 162 bent at an angle per plate, a rail member 162 welded at an angle per plate, or As shown in FIG. 20B, a rail member or the like in which a square member 162 ′ is fixed on a sleeper 177 is preferably used. FIG. 20C is a side view of the rail member and the like shown in FIG.
The angle (θ5) shown in FIG. 20 is preferably set to a value in the range of 70 to 110 °, for example, and more preferably set to a value in the range of 80 to 100 °.

According to the clamp rod jig of the present invention, the predetermined jig having a plurality of clamps arranged along the longitudinal direction of the long object can hold the holder even from a driving spindle having excellent rotational stability. A plurality of objects to be processed can be removed at the same time, and the plurality of objects to be processed can be directly moved to the next process.
Therefore, the clamp bar jig of the present invention is expected to contribute significantly to the improvement of the manufacturing efficiency of products manufactured through a painting and drying process using a spindle.
