[Example] In FIG. 1, which is a schematic vertical cross-sectional view, a rod-shaped work W is held in a holding mechanism 1 in a vertical position, and in that state, a plating tank 2, a pre-processing tank (not shown), and a post-processing tank are installed. They are crushed one after another by the processing liquid L in the processing tank pile.

A large number of plating tanks 2, pre-processing tanks, and post-processing tanks are each provided, and such cypresses are arranged in a row, for example, in a U shape. The workpiece W and the holding mechanism 1 are
It is transported along a group of shaped processing tanks as will be described later. Further, a loading area is provided above the population of the area (processing area) where such a group of processing tanks are installed, and an unloading area is provided below the exit of the processing area. In the loading area, the workpiece W is attached to the holding mechanism 1 as will be described later. In the unloading area, the processed workpiece W is removed from the holding mechanism 1 as will be described later. Also, in the unloading area, the work W
The holding mechanism 1 from which it has been removed is sent to a loading area in order to mount a new workpiece W thereon.

Next, the details of the holding machine ++Si 1 will be explained. The mechanism 1 includes a support arm 10 extending above the plating tank 2 in the width direction (left-right direction in FIG. 1). A vertical fixed rod 11 and a cylindrical rod support portion 12 are provided at the tip and middle portions of the support arm 10, respectively.
is fixed. The fixing rod 11 is constructed such that its lower half enters the inside of the plating treatment tank 2, and a bracket 1 protrudes horizontally from its lower end.
A lower holder 14 is fixed to the upper surface of 3. The lower holder 14 has four parts 15 on the upper side. The lower end of the workpiece W enters the four parts 15, and the lower end is seated on the inner surface of the recess 15, and the outer periphery of the lower end is held by the tapered inner peripheral surface of the four parts 15 so as not to move in the radial direction.

A movable rod 16 is perpendicular to the circumference of the rod support portion 12.
is held so that the JFI can move freely in the vertical direction.

The lower end of the movable rod 16 is a block-shaped upper holder 1
7 is connected as shown below. The upper holder 17 is a hollow member, and a small block 18 is housed inside the upper holder 17 so as to be slidable in the vertical direction.

The lower end of the movable rod 16 passes through a hole in the upper end wall of the upper holder 17 and is rigidly connected to the block 18. A shouting part is provided in the center of the lower surface of the block 18,
The recessed surface is seated on the upper end surface of the workpiece W. or,
The lower wall of the upper holder 17 is provided with a hole 19 into which the workpiece W is inserted. At the bottom of one hole is a taber rIH20 that expands downward.
is provided. The upper end portion of the workpiece W has a smaller diameter than the middle portion, and an annular step portion is formed between the small diameter upper end portion and the large diameter middle portion. The outer periphery of this annular stepped portion comes into contact with the tapered surface 20 to perform a masking function, thereby preventing plating from concentrating on the outer periphery of the stepped portion during electroplating work. Of course, when the tapered surface 20 comes into contact with the outer periphery of the stepped portion,
The upper part of the workpiece W is positioned in the radial direction.

As is clear from the above description, the block 18 descends due to its own weight and that of the movable rod 16, and is seated on the upper end of the workpiece W. Further, since the upper holder 17 can be moved up and down with respect to the movable rod 16 and the block 18, the holder 17 descends due to its own weight and is seated on the tapered surface 20 on the outer periphery of the stepped portion of the workpiece W. Therefore, even if the length of the work W is long or short, the upper holder 1
7 and the block 18 keep the upper end of the workpiece W sharply and dynamically as described above by their own weight.

In this way, the length of the workpiece W can be changed, and therefore the overall vertical position of the workpiece W within the processing tank 2 changes, so that the processing state of the workpiece W can be made uniform in accordance with this change. In order to do this, the length of the workpiece W, that is,
It is necessary to adjust the vertical position of the anode 30 in the plating tank 2. For this purpose, the following mechanism is adopted.

As mentioned above, each support arm 10 has two sets of fixed rods 1.
1 and rod support part 12 are provided, each holding mechanism 1 holds two works W at intervals in the longitudinal direction of the plating tank 2.

In the plating tank 2, the anode 30 is provided between each workpiece W and the adjacent side wall 31 of the plating tank 2 and between both works W. The anode 30 is a rod-shaped or band-shaped member extending vertically, and a large number of such anodes 30 are arranged in the longitudinal direction of the processing tank group, and each
The upper end portion is held by an anode holding member 32 or 33. A14 Power is supplied to the node 30 from a mechanism (not shown) above the anode holding parts 32, 32.

The upper ends of a net-like cage 35 surrounding the anode 30 are attached to the anode holding portions 32 and 33.

The cages 35 are continuous near the bottom of the plated plate 2.

The anode holding members 32 on both sides are fixed to the upper ends of the vertical members 36 at portions extending outward from the side walls 31 . Each vertical member 36 is held movably up and down by a vertical support 37 located near it. Although not shown, the vertical member 36 is provided with a female threaded portion, and a threaded shaft 38 perpendicular to the female threaded portion is connected. screw 1
The lower end of i+l+38 is connected to a drive mechanism 40 of motor e. via three transmissions. The drive mechanism 40 is provided near one transmission 39, and the drive mechanism 40 is provided near the other transmission 39.
and the drive mechanism 40 are connected via a horizontal intermediate shaft 41.

According to this configuration, when the screw shaft 38 is rotated by the drive mechanism 40, the vertical member 36 moves up and down, and the vertical position of the anode 30 changes, causing the anode 30 to correspond to the overall vertical position of the workpiece W. You can adjust it to the optimal vertical position.

Next, the holding mechanism 1 and the transport mechanism 3 for transporting the workpiece W will be explained. As described above, the holding mechanism 1 is transported so as to circulate through the loading area, the processing area, and the unloading area, and the transport mechanism 3 includes a pair of upper and lower drive chains 45 disposed along the transport path. ing. Each drive chain 45 is guided and supported by a suitable guide rail on a device fixing frame fixed to the base frame, and is driven by a motor or the like (not shown). A vertical column 46 is installed in the upper and lower drive chains 45. The column 46 is provided with rollers 47 at its ends, which run on rails provided on the fixed frame.

An elevating section 50 of the holding mechanism 1 is supported on this column 46 via rollers 51 so as to be movable up and down.

The elevating part 50 is a vertically long member, and the rollers 51 are attached to both ends thereof. The aforementioned support arm 16 has its base end rigidly fixed to the elevating section 50.

According to this structure, by driving the drive chain 45 to move the column 46 horizontally, the holding mechanism 1 and the workpiece W held therein are also moved between the column 46 and the elevating section 50 through the various areas. .

In addition to such horizontal movement, the workpiece W and the holding mechanism 1 must also be moved in the vertical direction, and for this purpose, the transport mechanism 3 is provided with a lifting mechanism 53.

The elevating mechanism 53 includes a vertical guide column 54 fixed to the frame, an elevating section 55 that is guided by the guide column 54 to be able to rise and fall freely, and a chain, a motor, etc. (not shown) for elevating the elevating section 55. It is equipped with Lifting section 5
5, a rail 56 extending horizontally is fixed. An arm 57 that protrudes above the rail 56 is provided at the upper end of the elevating section 50, and a roller 58 is attached to the tip of the arm 57.

When the lifting section 55 is raised by a motor and a chain (not shown), the rail 56 engages the rollers 58 from below and raises the lifting section 50 along the column 46, thereby causing the support mechanism 1 and the workpiece W to be raised. It is moved to a raised position above the processing tank 2. Also, the lifting section 55
When the holding mechanism 1 and the workpiece W are lowered together with the lifting section 10, the workpiece W is crushed by the processing liquid L from the plating processing tank 2.

The above-mentioned elevating mechanism 53 is provided only at the position where the holding mechanism 1 needs to be lifted, and at other positions (sections), it is provided similarly to the rail 56 in order to hold the holding mechanism 1 at a constant height. The rails are rigidly fixed to a suitable frame.

As described above, according to the present invention, the length of the workpiece W can be changed, so it is necessary to adjust the vertical position of the workpiece W in the plating tank 2 in accordance with the length.

For such position adjustment, the structure shown includes columns 46.
A vertical position adjustment mechanism 60 is provided for adjusting the lowering limit position of the lifting section 50, that is, the holding mechanism 1.

18 The vertical position adjustment mechanism 60 includes a vertical position adjustment part 61 provided near the back surface of the column 46 (the surface opposite to the holding mechanism 1). The vertical position adjustment member 61 is supported by the elevator 71 by a guide 62 fixed to the column 46. A rod-shaped member having a rack 63 is fixed to the surface of the vertical position adjustment member 6 opposite to the holding mechanism 1. The guide 62 is provided with a bracket l-65 (stopper support part) that protrudes to the vicinity of the rack 63.
An intermediate portion of a one-way stopper 66 is rotatably supported by the bracket 65. The stopper 66 is the rack 6
It is a lever-like member with a pawl at one end that engages with the rack 63, and the pawl and the rack 63 form a kind of ratchet mechanism. This ratchet mechanism allows the vertical position adjustment member 61 to move up relative to the column 46 in the operating state (meshing state), but prevents it from going down.

Further, the vertical position adjustment mechanism 60 includes a vertical position adjustment member 6
1, etc., a drive mechanism 70 and release mechanisms 19 and 71 are provided. The drive mechanism 70 is the vertical position adjustment member 6
1, and includes a vertical air cylinder 72 and a pusher t-73, which is driven upward by its rod, supported by a suitable frame. The upper end of the pusher 73 comes into contact with the bracket 74 at the lower end of the vertical position adjustment member 61 from below, and the pusher 7
When 3 is pushed upward, the vertical position adjustment part +4'61 is pushed upward, and from this, part 4'61 pushes up the arm 57 (or other suitable part) and lifts and lowers the elevating part 50. That is, the holding mechanism is raised above the column 46. After the vertical position (lowering limit raised position) is adjusted in this way, the stopper 66 engages with the rack 63 to prevent the holding mechanism 1 and the lifting section 50 from descending relative to the column 46. . As a result, the pair of workpieces W are always crushed by the processing liquid L in the plating tank 2 at predetermined vertical positions during a series of processing operations.

For a new work, it may be necessary to change the vertical position 20 of the holding machine drawing 1, and for this purpose the above-mentioned release mechanism 71 is provided. The release mechanism 71 is an air cylinder supported by a frame (not shown), and six brackets are fixed to the upper end of the cylinder rod. This bracket 69 protrudes above the end opposite to the claw of the stopper 66, and by operating the release mechanism 71, the bracket 1/69 pushes down the end of the stopper 66, thereby causing the stopper 66 to move upward. 1.Tuber 66
is removed from the rack 63, and the buzzer 61, that is, the holding part 5
A fall of 0 is allowed.

As is clear from the above description, the height adjustment of the holding mechanism 1 may be performed only in the loading area, and therefore the drive mechanism 70 and the release mechanism 71 are provided only in the loading area (or in the loading area and the unloading area). There is.

In order to mount the workpiece W between the holders 14 and 17 as described above, it is necessary to widen the gap between the holders 14 and 17 in advance. For this purpose, a holder position adjustment mechanism (rod control mechanism 75) for raising the upper 21 part holder 17 is provided in the loading area, unloading area, and franging area.

The rod control mechanism 75 includes a vertical air cylinder 76 supported by a frame and a pair of vertical guide rods 77. The guide rod 77 is raised and lowered with respect to the frame at a ratio of 1:1 (1:. The proximal ends of claws 79 are supported on both sides of the elevating part 78 via appropriate support shafts.The claws 79 are rotated between a horizontal position and a vertical position protruding upward. Although not clearly shown in the figure, a rotary actuator for rotation is also attached to the elevating section 78.

The pair of movable rods 16 protrude above the rod support portion 12, and have arms 80 at their upper ends that protrude in a direction toward each other.

A roller 81 is attached to the tip of each arm 80, and the claws 7 can be held on the roller 22 from below in a horizontal position.

According to this structure, the upper holder 17 and the block 18
When pulling up upward, first, with the claw 79 in a vertical position, the air cylinder 76 moves the H descending part 78 from above through between both rollers 81 to the bottom of the roller 81. Then, lower the claw 79 to a horizontal position,
Thereafter, the elevating section 78 is raised by the air cylinder 76. As a result, the claw 79 engages with the roller 81, the movable rod 16 is pulled up, and the upper holder 17 is raised. In this state, place the workpiece W between both holders 14 and 17, and then press 't+' IP? When the f section 78 is opened, the movable rod 16 and the like move down due to their own weight, and the upper holder 17 and block 18 engage with the upper end of the workpiece W as described above. After this fixation, the lifting portion 78 can be pulled up above the roller 81 by returning the claw 79 to the vertical position.

In this way, the workpiece W is mounted on the holding mechanism 1 in the loading area.
The mechanism for transferring the material up to the point will be explained with reference to FIG. 2 and FIG.

In FIG. 2, a work transfer mechanism 4 and a cotton supply mechanism 5 are provided as devices for attaching the work W to the holding mechanism 1.

Each holding mechanism 83 has a pair of fingers 85 that perform opening and closing operations.
and an appropriate cylinder mechanism to drive it,
The outer periphery of the workpiece W can be gripped from both sides by a pair of fingers 85. Although not shown, the holding mechanism 83 has a mechanism for raising and lowering it, a mechanism for moving it in the horizontal direction, and a mechanism for changing the distance between the pair of holding mechanisms 83. It is marked 1 digit. In the operation of holding the workpiece W on the workpiece supply mechanism 5, first, both holding mechanisms 8
3 has a narrow space between them, and descends from the upper position to the vicinity of the workpiece W with the fingers 85 open. When the finger 85 closes and grasps the workpiece W after descending, the holding mechanism 83 rises and moves horizontally to above the holding mechanism 86 of the workpiece transfer mechanism 4, during which (or after) the interval between both holding mechanisms 83 is reduced. The transfer mechanism 4's phantom holding machine slide 86
Expand until it matches the spacing between. The holding mechanisms 86 have a similar structure to the holding mechanisms 83, and a pair of fingers 87 protrudes upward from each holding mechanism 86. The holding mechanism 83 that has reached above the holding mechanism 86 then descends and holds the workpiece W.
