JPS59145789A - Continuous surface treating device for small parts - Google Patents

Abstract

PURPOSE:To enable simple and perfect surface treatment of small parts by conveying small parts into feeder troughs by a vibration feeder and running a surface treating liquid in the feeder troughs. CONSTITUTION:Small parts 6 are supplied through a feed port 4 into a vibration trough cylindrical vessel 1 under application of oscillation by an excitor 8 so that the parts are forced to ascend in vibrator troughs 2. On the other hand, a treating liquid such as for plating or washing is fed through a feed port 7 into the troughs 2 where the liquid is run down to treat the parts 6 and is discharged through an outlet 3. The treating liquid is discharged to the outside through an overflow hole 5. The troughs 2 upper than the port 5 play the role of draining the liquid from the parts 6 by oscillation.

Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, when plating or cleaning small parts, the small parts are placed in a basket or barrel and subjected to rocking, vibration, rotation, etc. so that the processing liquid comes into uniform contact with the small parts. In contrast to the sequential processing, in the present invention, small parts are placed in a 3-1 vibration trough cylindrical type (Fig. 1) or a straight 411 pipe (Fig. 1) and are vibrated (vibration direction is indicated by ■ in Fig. 1). (The movement path of the parts is ■ in Figure H) Using a continuous feeding device 1~, by flowing the processing liquid into the trough and by causing the small parts to vibrate in the liquid, complete contact with the liquid can be achieved. This is a surface treatment method that is characterized by the following features:

3-2 Next, the small parts removed from the processing liquid are continuously vibrated in the remaining trough to drain the liquid, so less liquid is brought into the next process compared to conventional processing methods.

3-3 The vibration trough can easily make continuous adjustments such as raising, lowering, and reversing small parts by adjusting the current, switching the circuit, and changing the slope of the return spring, so it can be adjusted under the best conditions according to the small parts. Surface treatment is possible.

FIG. 1 is a longitudinal sectional view of a cylindrical trough. Figure 1 is a longitudinal cross-sectional view of a straight trough. The small parts 6 inputted from the input port 4 are placed in a vibrator/
It rises in the trough 2 and is discharged from the outlet 3. The processing liquid flows in from the press-fitting lower, flows down in the trough, temporarily accumulates in the container 1, and exits from the overflow hole 5. The trough above the injection lower is useful for vibrating liquid drainage. 8 is a vibrator. In FIG. 1, ■ indicates the motion path of the small parts, and ■ indicates the direction of vibration.
