Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a barrel in a lubricating film treatment device, more specifically, materials to be treated such as pressed materials are charged into the barrel and sequentially immersed in a chemical treatment tank, thereby forming a phosphoric acid film on the material to be treated. It relates to barrels used in lubricant coating treatment, such as treatment, plating, or polishing.

Conventionally, the barrels used in this type of lubricant film processing apparatus include a cup-shaped swinging barrel 48 as shown in FIG. 10A, a rotary barrel 49 as shown in FIG. A rotary barrel 51 having a hinged lid 50 and a rotary barrel 54 secured to the lid 53 with bolts 52 as shown in FIG. 2 are used. However, in the conventional barrel described above, first of all, ta} In the case of the swinging barrel 48 of A above,
Because of the cup shape, processing liquid accumulates inside the barrel 48, resulting in very low processing efficiency and a drawback that it is easily deteriorated.

'b- In the case of the rotary barrel 49 with the above-mentioned opening, depending on the shape and dimensions of the material to be processed (workpiece), the workpiece may get caught on the blocking wall 55, making it impossible to completely eject the workpiece, and the efficiency is extremely low. There were flaws. {c' In the case of the rotary barrel 51 having the hinge lid 50 as shown in C above, the hinge structure lacks structural strength and has the disadvantage of being susceptible to corrosion and deterioration.

Furthermore, in the case of the rotary barrel 54 having the bolt-type lid 53 mentioned above, it is necessary to remove the bolt 52 and open/close the diamond 53 each time a workpiece is loaded or unloaded, which has a serious drawback in terms of workability. there were.

As described above, conventional barrels of this kind, especially barrels with lids, have the above-mentioned difficulties in the opening/closing structure of the barrel body and the lid, and this has been an obstacle to achieving continuous automation of the lubrication processing apparatus.

The object of the present invention is to solve these conventional problems5, and in particular, by improving the opening and closing structure of the barrel body and lid, it is possible to achieve continuous automation of the fishing slurry processing equipment, thereby saving manpower and labor. By streamlining work such as chlorination and by making it possible to immerse the barrel in liquid when adding materials, we aim to prevent damage to the workpiece and the barrel body.In addition, the lid can be opened and closed according to the rotation angle of the barrel body. The object of the present invention is to provide a barrel for a lubrication processing device that has particularly good workability in opening and closing the opening of the barrel body and has a mechanism that does not exist heretofore. That is, the present invention connects the sprocket wheel 7 provided on the driving shaft 1 side and the sprocket wheel 41 provided on the barrel main body 34 side with a transmission band, and also connects the sprocket wheel 11 provided on the driven shaft 8 side with the sprocket wheel 41 provided on the barrel main body 34 side. A sprocket wheel 38 provided on an opening/closing lid 35 that allows the closing part 32 to be opened and closed is connected by a transmission band, and the rotation of the driving shaft 1 is transmitted to the driven shaft 8 between the driving shaft 1 and the driven shaft 8. Provide a switching means such as a dog clutch that can freely switch between non-transmission,
The barrel body 34 and the opening/closing lid 35 are rotated simultaneously or separately.

That is, the present invention transmits the rotational force of the driving shaft 1 to the driven shaft 8 side by turning on the switching means, and transmits the rotation of the driving shaft 1 to the driven shaft 8 side by turning the switching means OFF. The driving shaft 1 and the driven shaft 8 whose transmission has been stopped
By making it possible to rotate each barrel individually, the barrel body 34 and the barrel body 34 can be easily rotated during processing steps in the lubricating film processing apparatus, such as loading material into the barrel 31, transferring the barrel 31 to each processing tank, and discharging the material from the barrel 31. The structure is such that each operation of the opening/closing lid 35 can be performed integrally or individually.

Therefore, according to the present invention, since the rotation of the barrel body and the rotation of the opening/closing lid can be performed simultaneously or separately, the entire processing process in the lubricant film treatment device can be automated, and as a result, work efficiency is dramatically improved compared to the conventional method. It becomes possible to process large quantities of materials,
Furthermore, we were able to achieve rationalization through labor savings and labor savings.

In addition, since material can be introduced while the barrel is submerged in the liquid, it has great practical effects, such as preventing damage to the material and the inner wall surface of the barrel body.

Embodiments of the present invention will be described below according to examples shown in the drawings.

Fig. 1 is a plan view showing the rotational drive mechanism of the barrel. In the figure, 1 is a driving shaft with a sprocket wheel 3 fixed to one end that engages with the lower rotation chain 2, and the other end is one pawl of the dog clutch. 4 are provided protrudingly on the outer periphery at predetermined intervals.

5 is a sprocket wheel that meshes with the upper rotation chain 6 provided in front of the clutch of the driving shaft 1; 7 is the sprocket wheel 5 and the sprocket wheel 3;
A sprocket wheel is a rotating body having a smaller diameter than both sprocket wheels 5 and 3 provided between them, and 8 is a driven shaft provided coaxially with the driving shaft 1 via a meshing clutch, and one end is connected to the driving shaft side. The other pawl 4', which is provided so as to be able to engage with one pawl 4 of the dog clutch that is protruding from the other end, is provided on the outer periphery of the clutch at a predetermined interval. A handle 10 is provided.

A rotary punch 56 is mounted on a motor shaft 58 of a motor 57, and has a notch 59 for inserting the lever 9 so that the lever 9 can be rotated 90'.

11 is a sprocket wheel fixed to the driven shaft 8, which is an example of a rotating body.

Reference numeral 12 designates a circular stopper plate fixed to the driven shaft 8, with a hole 13 formed in a portion thereof.

Reference numeral 14 designates a locking device consisting of shafts 17 and 17' that support a plate 16 having a pin 10 that can freely protrude and retract from the hole 13, and the shafts 17 and 17' are configured to be able to reciprocate.

Reference numeral 18 denotes a dog clutch as an example of a switching means configured to freely transmit or not transmit the rotational force of the driving shaft 1 to the side of the driven shaft 8. 4
When the pawl 4' on the driven shaft 8 side is engaged, the rotational force of the driving shaft 1 is transmitted to the driven shaft 8 side, and when the engagement is released, the rotational force of the driving shaft 1 is not transmitted to the driven shaft 8 side, and the driving shaft is axis 1
In this configuration, only the driven shaft 8 rotates, and the rotation of the driven shaft 8 is stopped.

19, as shown in Fig. 3, one end of the lower plate 20 is mounted between bearing plates 22 and 22' protruding from the frame 21 by means of a pin 23, and the end of the lower plate 20 is attached to a rod 24 that can freely move back and forth. This is a rocking body that is axially mounted on a connecting plate 25 and is integrally provided with an upper plate 26 of approximately the same shape as the lower plate 20, and the upper and lower portions of the approximately central portion are driven by the dog clutch 18. On one outer peripheral surface on the shaft 8 side,
Bolts 28 are fixed to recesses 27 and 27' provided below. Reference numeral 29 denotes a spring that normally pulls and biases the rod 24 toward the driving shaft 1 side.

Reference numeral 30 indicates a device for engaging and withdrawing the dog clutch 18, which is comprised of the rocking body 19 and a rod 24 biased by a spring 29.

31, as shown in FIG. 6, consists of a cylindrical barrel body 34 having a closing part 32 on the top surface and side walls 33, 33', and a side crescent-shaped opening/closing lid 35 which allows the closing part 32 to be opened and closed freely. The shafts 42, 42' on both sides are the pillars 36.
, 36', the barrel 31 is rotatably supported by bearings 37.

38 is a sprocket wheel fixed to one support piece 39' of the support pieces 39, 39' on both sides of the opening/closing lid 35, and the sprocket wheel 11 provided on the driven shaft 8
and are connected via an endless chain band 40 as a transmission band.

A sprocket wheel 41 is fixed to a shaft 42 on one side wall of the barrel body 34, and is connected to the sprocket wheel 7 on the drive shaft 1 via an endless chain band 43.

In the above embodiment, when the rod 24 is pulled in the direction of the mark A by the spring 29 as shown in FIG. 1, the swinging body 19 rotates in the direction of the arrow via the fulcrum pin 23. The driven shaft 8 to which the rocking body 19 is fixed with a bolt 28 is pulled in the direction of arrow A, and the driven shaft 8
The pawl 4' at one end and the pawl 4 at the other end of the driving shaft 1 are brought into engagement.

Therefore, when driving shaft 1 is rotated in this state, driving shaft 1
The rotation of the sprocket wheel 7 of the driving shaft 1 is transmitted to the sprocket wheel 41 of the barrel body 34 side via the endless chain band 43, and the rotation of the sprocket wheel 7 of the driving shaft 1 is transmitted to the sprocket wheel 41 of the barrel body 34 side via the dog clutch 18. At the same time as rotating the sprocket wheel 34, the rotation of the sprocket wheel 11 of the driven shaft 8 is transmitted to the sprocket wheel 38 on the opening/closing lid 35 side via the endless chain band 40, and the opening/closing diamond 35 is also rotated at the same time. Therefore, when the dog clutch 18 is in the ON state, the rotation of the driving shaft 1 is transmitted to the driving shaft 8, and the barrel body 34 and the opening/closing lid 36 can also rotate.

On the other hand, when the rod 24 is pulled in the direction of the arrow C against the tensile force of the spring 29, the swinging body 19 swings in the direction of the arrow D via the fulcrum, and at the same time the pawl 4' on the driven shaft 8 side is driven. It is detached from the pawl 4 on the shaft 1 side, and the dog clutch 18 is disengaged as shown in FIG. 8, turning OFF. Therefore, in this state, the rotation of the driving shaft 1 is not transmitted to the driven shaft 8 side and is blocked, so that the rotation of the sprocket wheel 7 due to the rotation of the driving shaft 1 is transferred to the sprocket on the barrel body 34 side via the chain band 43. It is transmitted to the wheel 41 and the barrel body 34
rotates, but the driven shaft 8 stops rotating and becomes able to rotate completely separately from the driving shaft 1.

That is, when the dog clutch 18 is in the OFF state as described above, if the motor 57 is driven to rotate the rotation village 56 by 90 degrees, the handle 10 will rotate 900 degrees by the lever 9, and only the driven shaft 8 will rotate. Therefore, the opening/closing lid 35 can be rotated independently of the barrel body 34 via the sprocket wheel 11.

In this way, by turning the dog clutch 18 ON or OFF to transmit or not transmit the rotation of the driving shaft 1 to the driven shaft 8 side, the barrel body and the opening/closing lid can be rotated simultaneously or individually. The series of processes of loading materials into barrels, rotating the barrels in each chemical treatment tank after loading, and discharging materials after treatment are extremely smooth and efficient, resulting in extremely high work efficiency and workability. It turned out to be excellent.

The operation of the barrel in a lubricating film processing apparatus will be described below as a specific example of its use.

First, explanation will be given according to FIG. ■ At station A in the same figure, the opening/closing lid 35 rotates 900 degrees clockwise around the outer circumference of the barrel body 34 to open the closing part 32 of the barrel body 34, and the dog clutch 18 is turned ON and as shown in FIG. Pin 1 with locking device 14 advanced toward driving shaft 1 as shown in FIG.
5 enters the hole 13 of the stopper plate 12 to stop the rotation of the driven shaft 8 and the driving shaft 1, resulting in a locked state.

Therefore, with the barrel 31 positioned in this manner and the barrel body 34 opened, the lower half of the barrel 31 is immersed in the water or hot water tank 44 as shown in FIG.

In this state, a workpiece 46 is charged into the barrel body 34 through the opening 32 of the material (workpiece) inputting chute 45 .

At this time, since the barrel 31 is partially submerged in the water or hot water bath 44 as described above, it is possible to prevent damage to the workpiece and the generation of noise that conventionally occur when charging the workpiece, and also to prevent damage to the barrel body due to impact. There are practical benefits that can alleviate this.

■ Next, after loading the material into the barrel at the A station, the chute 45 stops loading the material, and at the A station, the dog clutch 18 is turned OFF, and the rotation by the motor 57 is transferred through the rotation village 56. transmitting the rotation force to the handle 10 side by the lever 9 to rotate the driven shaft 8,
Contrary to the above, the opening/closing lid 35 is rotated 900 degrees counterclockwise to close the opening 32 of the barrel body 34, and in this state, the dog clutch 18 is turned on again.

Thereafter, the locking device 14 is moved backward as shown by the two-dot chain line in FIG. 1, and the protruding pin 15 is inserted into the hole 13 of the stopper plate 12 to release the lock.

As a result, the barrel 31 assumes a position in which it can freely rotate in any direction. (It will be in the state of A' station). (2) Next, lift the barrel 31 from the A station to the B station.

■ Next, while transferring from station B to station C, the barrel 31 is lowered and raised repeatedly, and the barrel is repeatedly diluted (during descent) and drained (drained (as raised)) in each chemical treatment tank. Perform the film treatment.

(2) Next, when the barrel 31 containing the film-treated workpiece reaches the C station, the barrel 31 is lowered to the next D station.

Thereafter, the barrel 31 is rotated 9 degrees counterclockwise at the D station (circle state). Thereafter, the dog clutch 18 is turned OFF at the D station, and the handle 10 is rotated via the lever 9 by the rotation of the rotation village 56 driven by the motor 57, and the driven shaft 8 is rotated to open and close only the lid 35. Rotate 900 degrees clockwise again and remove the barrel body 3.
4 is opened. After that, turn on the dog clutch 18 again (state D'').Furthermore, rotate the driving ball 1 at the D station, and rotate the barrel 31.
When the barrel body 34 is rotated clockwise, the film-treated workpiece stored in the barrel body 34 is discharged onto the next belt conveyor 47 (state D...).

After ejection, if the barrel 31 is rotated 330 degrees clockwise from the D'' position of the D station, D''
The posture becomes .

In this state, when the locking device 14 is moved forward and the protruding pin 15 is inserted into the hole 13 of the stopper plate 12 again, the barrel 31 will be in the locked state. ■ Next, after ejecting the workpiece.

The loaded barrel 31 is raised from station D to station E, then transferred to station F, and lowered from station F to station A, which is the waste material input position. Thereafter, by repeating the steps (1) to (2) above, all steps of material input, material coating treatment, and material discharge are performed. In the above embodiment, since it is possible to input the material with the barrel placed in the liquid, it is possible to automatically input the material, and it is also possible to prevent damage to the material and the barrel, as well as to prevent noise. There are advantages. Moreover, since the barrel body and the opening/closing diamond can be rotated or rotated simultaneously or separately, unmanned operation through automation is possible, and even in unmanned conditions, the barrel rotation is very smooth, which is a practical benefit. Further, in the above embodiment, a dog clutch is used as a means for switching between the driving shaft and the driven shaft. It may be possible to switch the rack and the ratchet by placing them next to each other or by disengaging them, or by connecting the barrel body and the opening/closing lid with a pin so that the switching can be performed by moving the pin in and out, or by other means.

In short, the switching means is by no means limited to the above-mentioned embodiments, as long as the rotation of the driving shaft can be freely switched between transmitting or not transmitting the rotation of the driving shaft to the driven shaft side between the driving shaft and the driven shaft. Furthermore, the rotating body and transmission body used as a means of transmitting the rotation of the driving shaft, barrel body, driven shaft, and opening/closing diamond are not limited to sprocket wheels and endless chain bands, but also known means such as small gears and large gears, or rotating bodies and belts. The key point is that the rotation of the driving shaft or the driven shaft is transmitted to the barrel body or the opening/closing lid side.
