Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fully automatic centrifugal barrel polishing device suitable for deburring, surface polishing, etc. of small articles.

(Prior art) Centrifugal barrel polishing devices with barrel pots that perform planetary rotation motion include vertical types with vertical rotational axes and horizontal types with horizontal turret rotational axes. They have also been widely used depending on the purpose of use. However, in small machines, the work of putting trout into the barrel pot is usually done manually, and in large vertical machines, where the lid cannot be opened and closed manually, the bottom lid must be opened.
It requires a complicated process of discharging the mass, opening the top lid, and loading the mass.With large horizontal machines, the turret must be rotated and mass discharging and mass input must be repeated for each barrel pot, making it difficult to polish. There was a drawback that it took a lot of time to discharge and input non-contributing mass.

Furthermore, with centrifugal barrel polishing equipment, it is necessary to sort the mass discharged from the barrel pot into workpieces and media after barrel polishing, and return only the media to the barrel pot. Since the next workpiece cannot be introduced until the sorting is finished, the actual operating rate, which directly contributes to polishing, cannot be increased.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned conventional problems, shortens the time required for mass input and mass discharge,
It was also completed with the aim of creating a centrifugal barrel polishing device that can immediately load the next workpiece into the barrel pot after polishing, thereby increasing the actual operating rate, which directly contributes to polishing.

(Means for Solving the Problems) The centrifugal barrel polishing device of the present invention, which attempts to solve the above-mentioned problems, has two barrel pots that perform planetary rotation motion, one set of two barrel pots, and one set of two barrel pots that perform planetary rotational motion.
A turret with a barrel pot on the other side of the set is pivoted around the horizontal axis of the machine base so that it can be tilted until it assumes a downward position, and the inside is divided by partitions in its lower part, and each compartment has a barrel pot. Receive the mass ejected from 2
Each stocker is installed so that it can be tilted individually.
Further, below both stockers, there is provided a sorter which separates the media from the masses discharged from each compartment of one stocker and then separates the media from the masses discharged individually from each compartment of the other stocker. At the outer periphery of the machine base, there is a bucket which returns media discharged from each compartment of the one stocker, sorted by a sorter, and discharged to each compartment of the one barrel pot, and a bucket from each compartment of the other stocker. The invention is characterized in that a chain-driven conveyor is provided, which is equipped with a bucket for returning the media that has been discharged, sorted by a sorter, and then discharged to each compartment of the other barrel pot.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

1 is a machine base, 2 is a pair of horizontal shafts attached to the machine base 1, 3 is a frame rotatably supported on the horizontal shaft 2, and 4 is rotatably mounted inside the frame 3. The turret 5A is one barrel pot which is attached as a set of two so that a planetary rotation movement can be made on this turret 4, and 5B is one barrel pot that is attached as a set of two pieces so that a planetary rotation movement can be made on this turret 4. This is the other barrel pot, which is attached as a set. As shown in FIG. 3, the turret 4 is revolved by a revolution motor 6 via a chain 7, and the turret 4 is
A sun gear 9 rotatably mounted on the central axis 8 of gear 11
While meshing with this sun gear 9 through the idler gear 11A, planetary rotational motion is performed. Reference numeral 12 denotes a turret tilting motor mounted on the machine base 1, which drives a reducer 14 via a chain 13.
5 to rotate the horizontal axis 2 to move the turret 4 to the first position.
It can be tilted from the vertical position shown in the figure to the downward position shown in Fig. 2. In addition, each barrel pot 5A, 5B has a central axis 8 of the turret 4.
A lid 17 that is opened and closed via a link mechanism 16 by a built-in hydraulic cylinder (not shown) is attached to each. The structure is such that four objects can be moved at the same time. On the other hand, on the machine base 1 in the lower part of the turret 4, as shown in FIG. 21A, 21
They are provided so that they can be tilted individually via B. Each stocker 18A, 18B is divided into two by a central partition 22, and has four compartments in total. These stockists 18
When the turret 4 tilts diagonally downward under the control of a control panel (not shown), the barrel pots 5A and 18B assume the upward position shown by solid lines in each figure.
After receiving the mass discharged from A and 5B, the mass is gradually tilted downward and the mass is transferred to the sorting machine 23 below.
It is now possible to discharge it little by little. The sorting machine 23 is a normal vibrating sieve type driven by a vibrator 24, which sorts the mass discharged from one barrel pot 5A into workpieces and media, drops the media onto the lower vibrating conveyor 25, and separates the workpieces from the workpieces. After discharging from the chute 26, the mass discharged from the other barrel pot 5B is sorted into workpieces and media, and the media are dropped onto the lower vibrating conveyor 25, while the workpieces are discharged from the chute 26. . Furthermore, in the outer peripheral part of such a machine base 1,
A chain-driven conveyor supported by a number of sprockets 27 is provided, and as shown in FIGS.
As shown in FIG. 2, the media are suspended one by one and discharged from the pair of media outlets 29 of the sorting machine 23. A pair of buckets 28A receives the media, and as shown in FIG. The media are then transferred to the upper part of one barrel pot 5A and put into a set of two barrel pots 5A, and the pair of buckets 28B then receive the media discharged from the media outlet 29 and are transferred to the other barrel pot 5B. The structure is such that the barrel pots 5B can be transferred to the upper part of the barrel and put into a set of two barrel pots 5B. Note that 30 is a motor for moving the bucket, and 31 is a workpiece input port.

(Function) The device configured like this first consists of the turret 4.
In the vertical position shown in FIG. 1, the four lids 17 of one barrel pot 5A and the other barrel pot 5B, which are made up of two barrel pots 5B, are simultaneously opened outward, and the lids 17 of the two barrel pots 5A and the other barrel pots 5B, which are made up of two barrel pots 5B, are opened simultaneously, and the lids 17 of the two barrel pots 5A and 5B are opened simultaneously. The squares stored in the other pair of buckets 28B are simultaneously thrown into one set of two barrel pots 5A and one set of two barrel pots 5B, and the buckets are immediately returned to the position shown in FIG. 2. Next, 4 lids 1
7 is closed, the revolution motor 6 causes the turret 4 to revolve, and the motor 10 rotates the sun gear 9, or the rotation of the sun gear is stopped and each barrel pot 5A, 5B is caused to perform planetary rotation motion. Perform normal centrifugal barrel polishing. At this time, the turret 4 may be tilted laterally or downward and its revolution may be stopped, or the pot may be rotated at a low speed to perform rotary barrel polishing. When the barrel polishing is thus completed, the turret 4 is tilted by the turret tilting motor 12 until it assumes an obliquely downward position, as shown in FIG. The cells in the barrel pot 5A and the barrel pot 5B are discharged to respective compartments in the stockers 18A and 18B below. At this time, since the stockers 18A and 18B are each divided into two parts, each barrel pot 5
The cells in each compartment A and 5B are not mixed with each other and are individually accommodated in four compartments. Each barrel pot 5A, which has finished discharging mass in this way,
5B immediately returns to the position shown in FIG. 1 together with the turret 4, receives the masses previously stored in the pair of buckets 28A and the other pair of buckets 28B, and begins the next centrifugal barrel polishing operation. On the other hand, stockers 18A and 18B, which received squares in their respective sections,
First, one stocker 18A is gradually tilted to gradually discharge the mass onto the sorting machine 23.
Sorts between work and media. At this time, the pair of bucket pots 28A suspended on the chain-driven conveyor are located below the pair of media outlet ports 29 of the sorting machine 23, and the barrel pots 5
The media discharged from A and sorted by the sorter 23 are received. Next, the other stocker 18B is gradually tilted to similarly sort the workpieces and media, and the media discharged from the other barrel pot 5B and sorted by the sorter 23 are transferred to the other stocker 18B as shown in FIG. Place in a pair of buckets 28B. Although this sorting work requires a certain amount of time, since the centrifugal barrel polishing work is carried out in parallel during this time, the actual operating rate of polishing is not reduced. In this way, each of the buckets 28A and 28B containing media is loaded with a workpiece and is waiting at the workpiece inputting position shown by the solid line in FIG. Now you can insert the next square. At this time,
The media discharged and sorted from one barrel pot 5A, which is made up of two media, will be put into the original one barrel pot 5A, and the same goes for the other barrel pot 5B, so please note that the two media are not mixed. Should. In this case, two batches of media are always operating in the apparatus. The operation of each part mentioned above is shown in the flowchart of FIG.

(Effects of the Invention) As is clear from the above description, the present invention has two advantages.
A turret equipped with two sets of barrel pots can be tilted around a horizontal axis until it is in a downward position, making it possible to discharge mass from the barrel pots in a very short time, and making it possible to discharge mass from the barrel pots in a very short time. The mass discharged from the barrel pot is separated into workpieces and media without mixing them, and the media can be easily returned to the original barrel pot using each bucket of a chain-driven conveyor, which would require an extremely large amount of work in the past. This system allows the loading and unloading of mass, which previously required time and effort, to be carried out automatically and in an extremely short time.
In addition, by providing two stockers whose interiors are divided into two, which tilt after receiving the mass, it is possible to sort the mass in parallel with polishing, making it possible to significantly improve the actual operating rate. Furthermore, in addition to this,
The apparatus of the present invention can be used for both vertical centrifugal barrel polishing and horizontal centrifugal barrel polishing;
It can also be used as a rotating barrel polisher,
Since two sets of barrel pots are provided, and two stockers with partitioned interiors and a corresponding number of buckets are provided, media can be returned to the original barrel pot from which they were taken out without mixing with each other. It also has many advantages, such as the fact that there is no risk of weight imbalance.

Therefore, the present invention can greatly contribute to the industry by solving the problems of conventional centrifugal barrel polishing devices.
