Description

[Detailed description of the invention] [Industrial application field] This invention is a method for transporting processed workpieces (coated products and other objects to be processed) from barrels such as barrels for barrel plating processes and barrels for barrel polishing. This invention relates to a barrel work unloading device.

More specifically, the present invention provides a barrel having a driven gear including a central driven gear centered on the central axis or an intermediate driven gear meshed with the central driven gear, and a workpiece unloading port bored on the central axis. The present invention relates to a barrel work carrying-out device that tilts a barrel for a punching process or other barrel to carry out a processed work to the outside.

[Background technology]

Originally, barrels for barrel plating processes are roughly divided into horizontal rotation type and tilted rotation type depending on the direction of the rotation axis, but the horizontal rotation type has large processing capacity and ease of automation. things are becoming more widespread. As for such horizontal rotation type,
In general, it has openings at both ends for attaching and detaching the cathode section, a number of perforations on the side wall for the passage of the plating bath, the passage of electrolytic current, and drainage, and a hole for loading and unloading the workpiece. A cylindrical body with an opening and closing part on the side wall is widely known, and a barrel plating method using this barrel is to place a workpiece into the barrel so that the axis passing through both openings is horizontal. The cathode part is immersed in the plating bath and rotated or oscillated about its axis, and the cathode part is inserted through both openings so as to make electrical contact with the internal workpiece, and the side wall of the barrel is inserted into the plating bath so as to be in electrical contact with the workpiece inside. A method has been adopted in which current is passed between anode portions disposed on both sides so as to face each other, that is, parallel to the above-mentioned axis.

However, in the conventional horizontal rotating barrel as described above, (a) the flow of the plating bath and the passage of the electrolytic current are carried out through a large number of perforations in the side wall;
The bath composition inside and outside the barrel tends to be unbalanced, and the electrical conductivity of the bath tends to be poor. (b) It is necessary to open and close the opening/closing part to take in and out the workpiece, which reduces productivity and slows down the barrel plating process. It is difficult to introduce consistent automation and robotization, and previous work tends to get stuck or remain in the opening/closing part.
(c) When washing the workpiece inside the barrel, a large amount of cleaning wastewater is discharged, requiring large-scale wastewater treatment equipment to prevent pollution; (d) When drying the workpiece, it is necessary to transfer the workpiece inside the barrel to a centrifugal dryer, etc., which causes problems such as a decrease in productivity and prevents the introduction of automation and robotization of the series of barrel plating processes. It was hot.

In order to solve the above-mentioned problems, it has recently been developed to have openings at both ends for at least the attachment and detachment of the cathode part, the loading and unloading of the workpiece, the circulation of the plating bath, and the passage of the electrolytic current. A barrel for the barrel plating process has been developed which consists of an empty body having a perforation in the side wall for the purpose of the barrel plating process. In this barrel for barrel plating process, the barrel containing the workpiece is immersed in the plating bath so that the axis passing through both openings is substantially horizontal, and the barrel is rotated or rocked about the axis. While moving the plating bath, electricity is applied between the cathode section inserted through both openings so as to make electrical contact with the internal workpiece, and the anode section placed with both openings facing each other in the plating bath. Barrel plating is then performed.

In the barrel improved in this way, one of the openings at both ends is used as an outlet for carrying out the workpiece, and therefore, when carrying out the workpiece, it is necessary to tilt the barrel so that the outlet is lowered. Furthermore, in order to effectively automate and robotize the workpiece unloading process and a series of processing steps including it, it goes without saying that it is desired to develop a workpiece unloading device that takes these into consideration.

[Problems that ideas should solve]

The present invention aims to provide a barrel work unloading device that can effectively unload processed workpieces from the improved barrel for barrel plating process as described above. In addition, this invention
The present invention aims to provide a barrel work unloading device that can effectively introduce automation and robotization.

[Technical means to solve the problem]

The workpiece unloading device for a barrel according to the present invention has at least a workpiece unloading port located at an end where the central axis passes.
A device for transporting processed workpieces from a barrel that has one or more driven gears around it and is rotatable around a central axis via the driven gears, the barrel is rotated with its central axis in a vertical plane. A barrel support means pivotally supported to be able to swing freely; a first swinging member that is attachable to and detachable from the barrel directly or indirectly and driven to swing in a vertical plane; and pivoted to the first swinging member. a second swinging member which is mounted on the second swinging member and is driven to swing in a vertical plane, and when the first swinging member is attached to the barrel and swings, the second swinging member It is characterized by consisting of a rotary drive gear that can engage with the driven gear of the barrel by swinging.

[Effect]

In the above configuration, when the first swinging member is attached to the barrel and is driven to swing downward, the barrel also swings downward and the workpiece exit of the barrel is lowered, and at the same time or subsequently, the second swinging member The moving member is driven to swing, and the rotary drive gear is engaged with the driven gear of the barrel, so that the barrel is driven to rotate about its central axis. In other words, the workpiece delivery port of the barrel not only moves downward, but also rotates around its central axis, so that the workpieces are effectively delivered to the outside.

In addition, after unloading the workpiece, follow the steps in the reverse order of the above.
That is, the rotational drive gear and the driven gear of the barrel are disengaged, the first swinging member and the barrel return to their normal positions, and the first swinging member is separated from the barrel.

In the present invention, there are no limitations to the configurations or rocking mechanisms of the first swinging member and the second swinging member. For example, if the first swing member is configured such that its swing axis is substantially coaxial with the barrel swing axis when it is attached to the barrel, the mechanism is simple and the first swing member is configured such that its swing axis is substantially coaxial with the barrel swing axis. More reliable rocking of the barrel can be achieved by integrating with the moving member. The first swinging member may be, for example, pivotally connected to a horizontally movable slide member via a hydraulic rotary actuator, and the first swinging member and the second swinging member may be, for example, The air cylinder may be pivotally connected to the cylinder tube and piston rod, respectively.

Further, the barrel support means may adopt a configuration in which the barrel is pivotally supported, for example, via an intermediate support member that supports the barrel rotatably around its central axis. In that case, the first swinging member may be attached to and detached from the barrel via the intermediate support member, and the attachment/detachment means may be, for example, attached to the intermediate support member in the central axis direction on the workpiece exit side of the barrel. This can be carried out by engaging and disengaging a presser plate, which is protruded from the first swinging member and faces the protruding presser plate. In addition, the barrel support means may include a structure in which the barrel is always biased in the direction in which the workpiece exit port is raised after the barrel is lowered, including the case where an intermediate support member such as the one described above is used, such as a spring mechanism or a barrel. If a configuration in which the workpiece is pivoted on an eccentric shaft is adopted, no external driving force is required when the barrel is raised to return to the home position after the workpiece is unloaded. The barrel support means of the present invention that pivots the barrel is useful not only for carrying out the work but also for loading the work, and in this case, as a means for tilting the barrel,
In addition to the same mechanism as the workpiece unloading device according to the present invention, for example, a cam mechanism or the like is used while the barrel is moved along the line together with the barrel support means, so that the workpiece input port is tilted so that it gradually rises. It is possible to adopt means to

In addition, if rotation of the barrel is not required when carrying out the workpiece, among the constituent elements of the present invention, a barrel support means for pivotally supporting the barrel so that its center axis can swing freely in a vertical plane, and a barrel The first rocking member is configured to be removable, driven to rock in a vertical plane, and configured such that its rocking axis substantially coincides with the rocking axis of the barrel when mounted on the barrel. This is sufficient, and it is possible to omit the structure for rotating the barrel when carrying out the workpiece, that is, the structure related to the second swing member and the rotational drive gear.
