JPS5863620A - Carrier for surface treatment apparatus - Google Patents

Abstract

PURPOSE:To provide a carrier where two pairs of hooks the interval of which can be adjusted are mounted on one slider, which can convey works in separate tanks at the same time by both hooks so as to heighten treatment efficiency. CONSTITUTION:A slider 16 is lowered to the lowermost position, and a truck 11 is travelled until hooks 22 of a fixed arm 17 are positioned just under engaging portions 27. An arm 18 is moved through a motor 19 and a speed reducer 19' by the motor 19 so that hooks 22 of the arm 18 are located just under the engaging portions 27 of another carrier bar 30. Subsequently, the slider 16 is lifted up so that the hooks 22 are engaged with the engaging portions 27 to pull up both works W together with holders 26 above tanks TK. After that, the truck 11 is travelled to move both works W above other two tanks TK, and the slider 16 is lowered to soak both works W in separate tanks TK, both ends of the carrier bar 30 being seated on saddles 32.

Description

[Detailed Description of the Invention] Final step #) is plating treatment, etc.! ! The present invention relates to a transport machine for sequentially transporting workpieces to a series of processing tanks in a surface processing process.

As shown in @limb, which is a partially cutaway diagram, in general plating treatment, there are many (7 in 1st) 0 tanks Tk1 s T kl...7 arranged in - row. . Tanks 7k and 47k are used for alkali cleaning, water washing, plating, etc.
Immersed in yKMM. The conveyor l is equipped with a trolley 3 that runs along a rail 2 above the tank group, and a slider 5 that can be raised and lowered below the trolley 3. It is designed to lock and transport items (tools). However, in the conventional product of the 1st [iJ], only 7 6 of the transport machine IKI group are installed, so it takes a long time to transport the workpiece, such as the tank y.
k,,rk.

When transferring the workpiece W%V in tank T'', 71cs, the transfer machine first travels empty to tank Tk, holds the workpiece V and transfers it to tank Tk, and then transfers it to tank Tk.
After returning to tank 1 empty, the workpiece W in tank 7kI must be transferred to tank Tk. As described above, since the conventional product has low conveyance efficiency, the mulberry processing efficiency is also low.

In order to eliminate the above-mentioned conventional problems, two sets of hooks are installed on the conveyor, so that workpieces in separate processing tanks can be held and conveyed at the same time. The explanation is as follows.

In the second perspective partial view, a series of tanks rks
1 supported by 7 frames not shown above y
A pair of rails 1o is arranged parallel to the tank Tkli, and the drive 1 guide plate 120 of the rail IQKd platform 11 is placed on its shoulder. Travel amount for driving the workpiece 12 -! and a speed reducer (both not shown) are housed in the truck 11. Vertical plumb 1 on trolley 11
5 is fixed, and the slider 16 is raised to the column 15. It can be installed freely.

The slider 16 is a motor for lifting and lowering the trolley II and a reduction gear 11.
are connected to each other via a chain (kl).

are approximately the bogie running direction F, l<forward and backward) Kj, respectively.
faiTh stands out. The pair of arms 17 are
) 4F16, but it is attached in such a way that it can be moved in the bogie running direction F%R with respect to the other pair of arms 1m11-j and the spacer flit. Arm 1
The base end of the 80 is connected to a motor 19 attached to the slider 16 via a reducer 19' (both have 1lii joint mechanisms), and the motor 19 moves the arm 18 in the bogie running direction F.
, H. Each pair of arms 17, 17, and 18.8 are spaced apart in the tank width W direction, and their tips are connected to the rod 21, and seven arms are connected in the opposite direction to the rod 21. There are 22 or more. The 7-piece 22 is, for example, a member in which a groove with a V-shaped cross section is formed by a front inclined wall 23 and a rear inclined wall 24 in the direction of carriage movement, and the retainer A26 is locked in the groove s2.
7 can be seated.

The holder 26 holds the plate-like workpiece W vertically and in the direction of carriage movement F%.
The frame 29 is held perpendicular to the frame 29, and a pair of vertical ends 31 extend upward from the upper edge of the frame 29 (carrier bar 30).
It protrudes toward the center.

Both sides of the carrier bar 30 are seated on saddles 32 provided on the upper edge of the wall of the tank T. Reference numeral 33 is a handle for the two adjacent tanks.

When moving the gear wt*, first lower the swing 16 to the lowest position, and run the carriage 11 in position 1, where the 7 hooks 22 of the wA constant arm 17 are directly below the lock 1127+LD. After #i7, the arm 18 is moved via the gear reducer 19' to the motor 1''-9 and the hook 22 of the arm 18 is locked to the other carrier bar 30C. so that it is directly below section 270. Next, the slider 16 is raised, the small locking capital 27 is locked with the seventh hook 22, and the yarn work W is pulled up together with the holder 26 above the tank rk. Next, the trolley 11 is run to move the Ayana work W above another 2N tank tko, and the slider 1
6, lower both work pieces W into separate tanks TkK, and place the 300M end of the carrier bar? , seat it on the Fru 32. In this operation, if the two pairs of newly seated 32.3zfkJo distances are different from the previously seated t dollars 32.32SekiO distance, then slider 1
6 before lowering, move the IIC movable 7-118 so that both carrier bars 30 are directly above the saddle 32. After the carrier bar 30 is seated on the saddle 32 and separated from the seventh link 22, the carrier bar 30 travels above the workpiece W to be transported next.

In addition, one arm (for example #
The locking portion 27 is locked with only the seven hooks 22 of f17), and the conveyance work can be performed with the other arm 18 in an empty state.

Next, the specific conveying feel will be explained. 3rd C is a transport process diagram, the horizontal axis is time, the vertical axis is tank 7, ~Tk,

The movement of arms 17, 18 and 7 links 22 during transportation is checked. Symbols M and B respectively indicate the movement of arm 17.1g (or 18.17). The head is arm 17,1
The time it took for B to lower the carrier 39 to the Vle 32 from 7Fkjl on the tank, 'τ was the time the trolley was running, and AT number showed its chest when stirring the 0W in the tank. There is. As is clear from No. 3, both arms (mu, ``) simultaneously pull up the workpieces in the tank ``l s T ``l and send them to the tank Tkh71c, for a certain period of time aT&j.
! After i, only the work in tank 7ks is pulled up and sent to tank Tjc4, then the work in tank Tk and tank T
After simultaneously transferring the workpieces of k, to tank rk,, Tk, only the workpiece of tank Tk is transferred to tank Tk, and from tank ik, it returns empty to tank T'hT'S and works on the same machine again. Repeat. Therefore, each time is AT-10 seconds, tm5 seconds, ? -10 seconds, the transport cycle time is (, dTX4) + (tXl) + (T

It becomes 0 seconds + 160 seconds - 270 seconds, and the third i10 Yang match is longer by sigs seconds.

That’s all! As explained above, according to the present invention, it is possible to produce 11 iL of mackerel.One slider 1GK is equipped with 2kk1tD7ts 22, and both 7ts 22 can simultaneously transport the inner O work W to separate tanks τ. Therefore, it is possible to shorten the transfer @O operation cycle time and reduce the waste movement◆, and it is possible to prevent the workpiece W from being immersed in the tank Tk for a long time unnecessarily, thereby increasing the processing efficiency. can.

In addition, the lifting platform that embodies the present invention is 7kuku22 of 2111%.
It is also possible to move the O-arms 17 and 18 in the traveling direction of the bogie in order to narrow the distance between them.
