Description

[Detailed description of the invention] Industrial application field The present invention is an automatic container inverter used primarily to invert a container placed on a mounting table and take out a processed product in the final process of an automatic processing device. It is related to the device. Conventional technology Automatic processing equipment using this type of container is as follows:
2. Description of the Related Art There is a plating processing apparatus that processes a large number of small items at one time and performs a dipping process by placing the workpieces after barrel plating into a basket. Looking at the container reversing devices adopted in the final process of these plating post-processing devices, the means for locking the containers in these devices is a manually controlled fixture or a hydraulic cylinder, etc. that locks the baskets placed on the mounting table. A method of restraining the device to the mounting table using a fixture controlled by a drive device was employed. Problems to be solved by the invention Among the conventional techniques, the former requires cumbersome operations each time because it is manually controlled, and has the drawback that it is difficult to adopt it in an automatic processing device aimed at saving labor. Even if the latter can be adopted for automation, it not only requires a dedicated drive device such as a hydraulic cylinder, but also requires an automatic control operation mechanism to operate it at a certain timing. The drawback was that it was extremely expensive. In this respect, the present invention is an automatic container reversing device that can be effectively used for reversing baskets in post-plating processing equipment, and is intended to automate the container locking means therein with an extremely simple structure. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention specifically provides a receiving frame 19 for fitting and holding the container 8 on the mounting table 18, and mounts the container on the rear side of the mounting table 18 in the reversal direction. The lower end of the hook 20 is pivoted to swing between a locked state in which the upper edge 24 of the container 8 is locked and the container 8 is restrained on the mounting table 18, and an unlocked state in an inclined position in which the restraint is released. At the same time, the center of gravity W of the hook 20 when the hook 20 is positioned in the locked state in the initial posture of the mounting table 18 is configured to be located outside the vertical line A passing through the lower end pivot point a. The hook 2 is moved by the movement of the center of gravity W around the pivot point a due to a change in attitude due to the reversal of the table 18.
0 is characterized in that it is configured to operate automatically. Function After the container 8 is placed on the mounting table 18 in the final process of the automatic processing device, when the mounting table 18 is reversed from its initial position, the hook 20 is
The attitude of the robot also changes, and when the tilted attitude in the unlocked state exceeds the vertical attitude and begins to incline to the opposite side, and the center of gravity W moves to the opposite side beyond the vertical line passing through the lower end pivot point a at that point, The actuating force at its center of gravity quickly switches the container 8 into the locked state, causing the container 8 to move to its final inverted position in the locked state restrained relative to the mounting table 18, thereby allowing the container 8 to hold its contents. Discharging is automatic.
Furthermore, when the container 8 is returned to its original initial position together with the mounting table 18 from the inverted position, the center of gravity W of the hook 20 in that state is located outside the vertical line passing through the lower end pivot point a. Therefore, at the same time that the container 8 and the mounting table 18 return to their original positions, the hook 20 is automatically returned to its original unlocked state by its own weight, and as a result, the container 18 This makes it possible to remove the container 18 and bring in the next container 18. Effects As described above, the present invention can be used as an operating means for operating at a fixed timing the movement of the center of gravity W around the pivot point a as the posture of the hook 20 changes as the mounting table 18 is reversed. By using the center of gravity of the hook 20 as a driving force, the hook 20 is automatically switched between the locked state and the unlocked state at a constant timing as the mounting table 18 is reversed. Therefore, it has become possible to easily automate the locking means in an automatic container reversing device using a very simple single hook 20 that only takes into consideration the dynamic posture change of the hook 20 and the overall weight balance associated with it. It is ivy. In other words, the present invention does not require a dedicated drive device such as a hydraulic cylinder or an operating mechanism for operating it at a fixed timing, as is the case in the past. This is extremely remarkable. Embodiment Next, as an embodiment of the automatic container reversing device according to the present invention, a basket reversing device is used in which processed workpieces are taken out by reversing a basket (hereinafter referred to as a container) in a plating post-processing device. Explain in detail. In the figure, 1 is a plating processing device in which a pre-treatment bath, a washing tank, a lock bath, etc. are arranged in a row in a known process, and 2 is a plating processing device in which a washing tank, a chromate bath, etc. are arranged in parallel with the plating processing device 1 in a known process. This is a post-treatment device that is arranged in a row in the process and performs a dipping treatment mainly to prevent discoloration after plating and to impart gloss or (and) coloring. This is a centrifugal dewatering device for final drying of the plated products. To outline the series of steps in these devices, in the plating process, the first carrier 4 reciprocates along the top of each tank of the plating device 1.
The barrel 6 is immersed in each tank such as a pre-treatment tank, a washing tank, and a plating bath in a predetermined order using a lifting device 5 equipped with a barrel drive device to sequentially perform plating treatment. It is. Next, the workpiece after the plating process is placed in the funnel-shaped receiver 7 at the left end in the drawing.
At this point, the sample is discharged from the barrel 6 and placed in the basket 8 located below the receiving part 7, and the basket 8 is then moved back and forth by a driving device such as a cylinder 9 to the starting end position of the post-processing step. be moved to In this state, the suspension member 12 installed on the second carrier 11 reciprocates along the upper part of each tank of the after-treatment device 2, and is suspended from the suspension member 12 to provide a predetermined position in each tank such as a flush tank and a chromium bathtub. The baskets 8 are immersed in order and post-processing is performed in sequence. Also, this second
After completing the post-processing using the carrier 11, a centrifugal dewatering device 3 is located on the opposite side beyond the starting point position.
The whole basket 8 was brought in for drying treatment.
After the final drying process has been completed, the processed products are taken out from the centrifugal dewatering device 3 along with the basket 8 , placed on the adjacent reversing device 13, and then taken out for the packaging process by reversing the basket 8. be. Incidentally, these series of steps are performed continuously and automatically by sequence control each time the set operation in each step is completed. Next, the centrifugal dehydration device 3 will be explained. It has an opening/closing lid 14, a dehydration basket 15 that fits and holds the basket 8 , a forced hot air blower 16 that supplies hot air to the dehydration basket 15, and a steam blower in the initial stage of drying. It consists of a steam jet nozzle 17 that supplies steam to the basket 8 . Then, to explain the reversing device 13 according to the present invention, as a whole, it includes a mounting table 18, a receiving frame 19,
It consists of a hook 20, a crank mechanism 21 for driving the mounting table, and a chute 22, and is mounted on the mounting table 18 which is pivoted 23 to the machine frame at one end on the reversal direction side and slightly above the mounting surface. A cylindrical receiving frame 19 that fits and holds the basket 8 is installed upright, and the upper edge 24 of the basket 8 is locked on the rear side of the mounting table 18 in the reversal direction and at a position close to the mounting surface, so that the basket 8 is placed on the mounting table 18. The lower ends of the pair of hooks 20, 20, which swing between a locked state in which the device is restrained upward and an unlocked state in an inclined position in which the restraint is released, are pivoted, and when the mounting table 19 is in its initial position, Hook 2 when hook 20 is in the locked state
0 is configured so that the center of gravity W of 0 is located outside the vertical line A passing through the lower end pivot point a, and the center of gravity W moves around the pivot point a due to a change in attitude due to the reversal of the mounting table 18. Accordingly, the lift 20 is configured to operate automatically. Therefore, the workpieces after the drying process, which is the final step of the plating post-processing device 2, are taken out from the centrifugal dewatering device 3 along with the basket 8 and transferred to the mounting table 1 of the reversing device 13.
8, the mounting table 18 is placed on the crank mechanism 2.
When the hooks 20, 20 are reversed from the initial position by 1, the positions of the hooks 20, 20 change sequentially as the mounting table 18 is reversed, and the hooks 20, 20 start to tilt from the tilted position in the locked state to the opposite side beyond the vertical position. When the center of gravity W moves to the opposite side beyond the vertical line passing through the lower end pivot point a at that point, the basket 8 is rapidly switched to the locked state by the operating force of its own weight.
are sequentially shifted to the final inverted position in a locked state in which they are restrained relative to the mounting table 18, whereby the processed workpiece is automatically discharged to the packaging process side via the chute 22. It is something. Furthermore, when the basket 8 is returned to its original initial position together with the mounting table 18 from the inverted position, the center of gravity W of each hook 20, 20 in that state is located outside of the vertical line A passing through the lower end pivot point a. Therefore, at the same time as the basket 8 and the mounting table 18 return to their original positions, the hooks 20, 20 are also automatically returned to their original unlocked state by their own weight. This allows the basket 8 to be removed and the next basket 8 to be brought in. The hooks 20, 20 are constructed so that the weight is greater toward the upper end having the engaging portion, and the center of gravity W when the mounting table 18 is in the initial posture and locked state passes through the lower end pivot point a. The further outside the vertical line A is located, the more stable the switching operation due to its own weight becomes. Also, the contact member 2
Regarding the inclination angle (the angle between the line connecting the center of gravity W and the pivot point a and the vertical line) in the unlocked state, which is regulated by 5, the mounting surface of the mounting table 18 becomes vertical and the basket 8 exceeds the horizontal state. The angle is free as long as the center of gravity W moves to the opposite side and switches to the locking means before it is reversed, but considering the overall reversal speed and the operating speed due to its own weight,
It is better to set the angle to around 30°. Further, as the drive device for the mounting table 18, a reciprocating rotation drive device using a chain other than the crank mechanism 21 and a clutch switching may be adopted.
