Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a barrel polishing device having a watch frame support, and particularly to a barrel polishing device having a watch frame support which is applied to an article whose entire surface of the watch frame is to be uniformly polished. Regarding equipment. [Prior Art] Conventionally, several types of barrel polishing devices of this type are known. Patent No. 131479 (August 4, 1948) states that ``A rotating cylinder that rotates in a constant direction is provided with an object holding frame that rotates in the same direction as the cylinder in the axial direction of the cylinder. A "rotary sander pivotably mounted on a shell wall in close proximity to the shell wall" is described. Further, Japanese Utility Model Publication No. 51-41403 describes a "(polishing) cleaning device in which a wire mesh drum and a blade plate are rotated inside a rotating drum." These barrel polishing devices generally perform polishing by rotating the material to be polished together with the abrasive material without fixing the material within the drum. However, it is not necessarily suitable for objects that are easily deformed or workpieces with complicated shapes, etc. from the viewpoint of processing finish, work efficiency, etc. For this reason, a method is adopted in which the material to be polished is fixed within the barrel. For example, eyeglass frame holders for simultaneously holding a plurality of eyeglass frames have been proposed, such as Japanese Utility Model Publication No. 54-27671 and Japanese Utility Model Publication No. 56-14038. [Problems to be Solved by the Invention] However, although the above-mentioned holder is excellent for glasses, it cannot be applied to small and precise metal structures such as watch frames. Also, when taking out the eyeglass frame holder from inside the barrel,
It is difficult to remove the object to be polished when it is in the reverse position. Furthermore, when judging the polishing situation during polishing, it is inconvenient because it cannot be seen if the object to be polished is reversed. The present invention has been achieved from the above viewpoints. SUMMARY OF THE INVENTION An object of the present invention is to provide a barrel polishing device having a watch frame support for holding a workpiece of a watch frame within the barrel. Still another object of the present invention is to provide a barrel polishing device having a watch frame support that allows the support for holding a workpiece of a watch frame within the barrel to be easily taken out from the barrel. [Means for solving the above problems] In order to solve the above problems, the present invention takes the following measures. The first invention comprises: a) a rotationally driven barrel 10; b) a polished part support rod 110 that rotates on an axis parallel to the rotational axis of the barrel 10 and is mounted inside the barrel 10; c) of the barrel 10. The barrel 10 and the part-to-be-polished support rod 110 are arranged so as to roll in proportion to the rotation.

This is a barrel polishing device having a clock frame support consisting of and m. [Operation of the embodiment] The polishing medium 15 is charged into the barrel 10. The part to be polished is attached to the mounting devices 80 at eight locations within the barrel 10 using support rods 110 and 160 for the part to be polished.
Next, when the barrel polishing device is rotated in the direction R shown in FIG. 6, the polishing medium 15 within the barrel 10 circulates within the barrel 10 as shown by arrow F. The polishing medium 15 inside the barrel 10 is lifted in the rotation direction R by the rotation of the barrel 10, slides down by gravity near the central axis, and reaches the lowest apex (the lowest apex) of the polygon of the barrel 10. Beyond 16) in Figure 6, the side of barrel 10 (17 in Figure 6)
, and is further lifted up and circulated by the rotation of the barrel 10. In this case, since the part-to-be-polished support rod 110 is provided near the apex of the barrel polygon, the polishing medium 110
The part to be polished will be uniformly polished at the reflux point where the plate 5 falls, turns over and is lifted up. This will be explained in comparison with the conventional example in FIGS. 6-a and 6-b. FIG. 6-a is a diagram schematically illustrating the present invention, and shows that the part-to-be-polished support rod 110 is well polished at the recirculation point of the fall and reversal of the polishing medium 15. FIG. 6-b shows a support rod 110 as in the conventional case.
is attached near the center of the polygonal side of the barrel 10, and in this case, the polishing medium 15 falling inside the barrel 10 hits the apex 16 of the polygon.
After colliding with the side 17 beyond the point and consuming energy, the part to be polished reaches the support rod 110.
Since the present invention is configured as described above, the part to be polished can be polished satisfactorily and uniformly. Further, in the present invention, the driving sprocket of the support rod can be always stopped at a fixed position by a fixed position stop mark.

Another embodiment 172 of the support member 0 is shown.
This is done by arranging a pair of support rods 168 facing each other, and connecting the main rods 161 and 16 with bolts 171 and 171, respectively.
It screws onto 2. Safety Means 70 Next, an embodiment of the safety device of the present invention will be described. This safety means 70 is schematically illustrated in FIG. Since the mounting device 80 and the polished part support rods 110, 160 of the present invention are made of metal, and the polished parts 150, 180 are also made of metal, it is possible to ensure electrical safety. .
FIG. 2 shows one side of the barrel polishing rod of the present invention on which the driving force transmission means 50 is not provided, and the outside of the mounting members 71, 72 of the eight mounting devices 80 is visible. The mounting members are divided into two groups 71 and 72, and each group is electrically connected by conductive wires 73 and 74, respectively. The terminal end of this conducting wire 78 is connected to a rotating ring 76 of a bearing 75 of the barrel 10, and from this rotating ring 76 to a fixed terminal 78 by a sliding contact 77 having elastic force. On the other hand, the conductive wire 74 is connected to the rotating shaft by a suitable sliding contact (not shown) inside the barrel 10, and is connected to the other fixed terminal 79. If an electrical short circuit between the terminals 78 and 79 is detected, the piece to be polished comes off and rolls inside the barrel 10, or the support rod comes off.
When the terminals 78 and 79 are short-circuited, an abnormality can be detected and the drive can be stopped. In addition, if the part to be polished is small and does not have enough dimensions to straddle the support rods 110 and 160 for the part to be polished even if it falls off, a weak current is constantly passed through the part to be polished. It is also possible to adopt a method of detecting falling off. Drive Transmission Means 50 FIG. 1 shows the drive force transmission means 50 of the barrel polishing apparatus of the present invention. The driving force from the drive motor M is transmitted to a barrel drive pulley or sprocket 52 via a first transmission belt 51. A first transmission pulley 58 is keyed on the rotating shaft coaxially with this barrel drive pulley 52. This first transmission pulley 58 rotates the support rod via a second transmission belt 54, a third transmission pulley 56 keyed coaxially with this second transmission pulley 55, and a third transmission belt 57. Pulley 5
8,...58. A tension roller 59 is provided in the middle of the third power transmission belt 57. The rotation speed of the barrel 10 is preferably about 20 rpm, but the rotation speed can be adjusted using an inverter. As the barrel 10 rotates, the support rods 110 and 160 for the part to be polished also roll according to the part to be polished.
The rotation speed is 1/2. In other words, barrel 10 is 1
When rotated, the part-to-be-polished support rods 110, 160 are reversed, and the part to be polished can be polished uniformly. Here, a chain may be used instead of a belt, and a sprocket may be used instead of a pulley. At least one of the support rod rotation pulleys 58 is marked with a mark 60, and depending on this position,
It can be determined whether the mounting position of the support rod mounting device 80 mounted inside the barrel 10 is a normal position or a reversed position. That is, the mark 60 can be taken out by stopping at an angle that makes it easy to attach and take out the barrel when the polished part support rods 110, 160 are attached and taken out. This support rod mounting device 80 is mounted within the barrel 10 as shown in FIG. That is, for the lid 11 of the barrel 10, each support space 89, ... 89 of the mounting devices 81 to 84 faces the lid 11 side, and for the lid 12 of the barrel 10, each support space of the mounting devices 85 to 88 faces toward the lid 11 side. 89,...89 are attached facing the lid 12 side, and the lids 11, 1
2 to facilitate the work of attaching the polished part support rods 110, 160 to the attaching devices 80, 81-88. In FIG. 8, support pieces 167 of the watch frame,...
An example of a structure in which the mounting angle of 167 can be adjusted is shown. In this case, the support member 167 is screwed onto the adjustment pieces 173, 173 and is supported so as to be able to pivot relative to the main rod 162. The other end of this adjustment piece 173 is connected to the adjustment rod 1.
74 by a pin 178, and the end of the adjustment rod 174 has a threaded portion 175 into which nuts 176, 177 are screwed to adjustably support the connection 164. ing. This makes it possible to adjust the attachment to the optimum angle depending on the part to be polished. Although the mounting angle adjustment mechanism has been described for only one embodiment, this is not limited to this example, and can be applied to any part to be polished. Operation When operating the barrel polishing device of the present invention,
It is carried out according to the following steps. (1) Turn on the power switch. (2) Pour the polishing medium into the barrel 10. (3) Set the piece to be polished on the support rod and attach it to the eight mounting devices 80 inside the barrel 10. (4) Close the barrel lid and turn off the emergency stop lamp.
(Emergency stop light is on)
If it remains in the NO state, there is a problem with the support rod setting). (5) Press the barrel polishing device start button to start polishing work. (6) Set the polishing time (e.g. 24hr) and forward/reverse timer (e.g. 6hr). (7) When taking out the part to be polished after polishing,
The mark 60 on the sprocket 58 is adjusted manually or the like so that it is at a predetermined position. (8) Remove the lid of the barrel 10, take out the piece to be polished, and complete one cycle. Even if the polishing machine stops midway through work due to a power outage, the timer will not advance and the work can continue for the remaining time after restarting. [Effects of the Invention] As described in detail above, the barrel polishing device having a watch frame support according to the first aspect of the present invention can now uniformly and efficiently polish even a watch frame that could not be barrel-polished in the past. In addition, the barrel polishing device having a watch frame support according to the second aspect of the present invention has marks on the support rod rotating pulley, so that the watch frame support rod can be taken out from the barrel at a fixed angle position, resulting in efficient work. Can be done.
