[0010] In the following, an example will be described in which the part to be separated is a gasket. Generally, gaskets, which are shaped like eyeglass frames bent into a U-shape, are components that tend to become tangled. However, they are shipped in nylon bags without consideration for preventing tangling, so they are already tangled. The gaskets, which are shaped like glasses bent into a U-shape, are tangled together, making it difficult to remove just one. Furthermore, the gasket is a very delicate and important part, and if it is scratched, deformed, or the surface plating is worn down, it will cause oil leaks and the brakes will not work.

[0011] Therefore, in the following embodiment, taking these problems into consideration, a separation device will be described that prevents the components from re-entangling and is less likely to be damaged.

[0012] First embodiment Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is an internal plan view of a separation device according to the first embodiment. Fig. 2 is an internal plan view and an internal side view of the separation device according to the first embodiment. Fig. 3 is an internal rear view of the separation device according to the first embodiment. Fig. 4 is a top view and an internal side view of the separation device according to the first embodiment.

[0013] 1 to 4, the separating device 100 includes a motor 101, a driving gear 102, eccentric gears 103-1 and 103-2, a transmission gear 104, free rollers 105-1 to 105-4, a top plate 106, a component jump-out prevention plate 107, a Teflon (registered trademark) tape 108, and a control unit (not shown). The swing mechanism is composed of the motor 101, the driving gear 102, the eccentric gears 103-1 and 103-2, and the transmission gear 104.

[0014] The motor 101 is an electric motor having a rotating shaft connected to a drive gear 102. The motor 101 rotates the drive gear 102.

[0015] The drive gear 102 transmits the rotational motion to the eccentric gear 103-1 by meshing its teeth with the eccentric gear 103-1. Similarly, the eccentric gear 103-1 transmits the rotational motion to the transmission gear 104 by meshing its teeth with the transmission gear 104. The transmission gear 104 transmits the rotational motion to the eccentric gear 103-2 by meshing its teeth with the eccentric gear 103-2.

[0016] The eccentric gear 103-1 has an eccentric pin 131-1 that protrudes at a position away from the rotation axis. Similarly, the eccentric gear 103-2 has an eccentric pin 131-2 that protrudes at a position away from the rotation axis. The eccentric pins 131-1 and 131-2 are in contact with the top plate 106. The positions where the eccentric pins 131-1 and 131-2 are in contact with the top plate 106 are higher than the positions where the free rollers 105-1 to 105-4 are in contact with the top plate 106.

[0017] When the eccentric gears 103-1 and 103-2 rotate, the eccentric pins 131-1 and 131-2 rotate about the rotation axis, As a result, the positions at which the eccentric pins 131-1 and 131-2 contact the top plate 106 change, causing the top plate 106 to swing.

[0018] The free rollers 105-1 to 105-4 are ball bearings, and support the top plate 106 so that it is approximately horizontal.

[0019] The top plate 106 is a plate-shaped body with an uneven upper surface. The top plate 106 is preferably an embossed plate with smooth unevenness on the surface. With this configuration, the smooth unevenness moves eccentrically so as to lightly catch the parts, and the parts can be separated without being damaged. After separation, the parts move so as to slide on the convex parts at points of contact and remain in place within the eccentricity. Figure 5 is a diagram showing an example of a separation pattern by the separation device according to the first embodiment. As shown in Figure 5, the parts move eccentrically so as to lightly catch the convexities and are separated.

[0020] In the unlikely event that dust falls onto top plate 106, if it is a flat plate, the dust will be on the surface and may rub against the components, causing damage. In contrast, by using an embossed plate with bumps for top plate 106, dust will collect in the depressions and fall outside the outer frame by the centrifugal force of the eccentric motion along the recesses, preventing the components from being scratched.

[0021] The component jump-out prevention plate 107 is a plate having a hole penetrating the center. The component jump-out prevention plate 107 is placed on the top plate 106. The space formed by the component jump-out prevention plate 107 and the top plate 106 has an open top.

[0022] A control unit (not shown) controls the power supplied to the motor 101. For example, the control unit changes the voltage applied to the motor 101 or reverses the polarity. Specifically, the gear ratio is adjusted so that the eccentric gears 103-1 and 103-2 to be eccentric rotate at an appropriate speed, and a fine adjustment volume is provided in the control unit. In this way, the parts can be disassembled with an appropriate rotational motion without damaging them. Furthermore, by providing a fine adjustment volume for the rotational motion in the control unit, the rotational motion can be finely adjusted to obtain an optimal rotational motion.

[0023] Also, eccentric gears 103-1 and 103-2 with eccentric pins are installed in positions where the top plate 106 can rotate stably so that they move synchronously in the vertical direction. In this way, as shown in FIG. 4, multiple eccentric pins 131-1 and 131-2 rotate, and the top plate 106 can rotate eccentrically while stabilizing its movement. In addition, since the top plate 106 is oscillated by eccentric movement, it is quieter than the vibration of a vibrator. Furthermore, while the top plate 106 may vibrate if there is only one eccentric gear, by providing multiple eccentric gears that rotate simultaneously, the eccentric pins 131-1 and 131-2 eccentrically move along the same orbit, and the top plate 106 can rotate stably.

[0024] In addition, the free rollers 105-1 to 105-4 that support the top plate 106 are installed parallel to each other at an appropriate height so that the eccentric pin will not fall out. This provides stable eccentric movement without tilt or rattle. The plate into which the eccentric pins 131-1 and 131-2 fit and the top plate 106 are fixed with bolts from a cylinder made of a soft material that is larger than the hole diameter of the parts at the top. With this configuration, the parts can be disassembled without damaging them by making a countersink to prevent the bolt heads from protruding. Also, because it is larger than the hole diameter, the parts will not fit into the holes.

[0025] In addition, a flat material that absorbs shock is attached to the area of ​​the underside of the top plate 106 that the free rollers contact. For example, Teflon tape 108 having a predetermined thickness is attached to the area of ​​the underside of the top plate 106 that the free rollers contact. This configuration prevents the free rollers from picking up unevenness and causing up-and-down movement when they are directly applied to the embossed plate, and achieves smooth rotation. Damage to the parts due to up-and-down movement can be prevented. Vibrations and noise due to up-and-down movement can be prevented. Wear of the eccentric pins 131-1 and 131-2 and the parts that contact them (such as the eccentric pins and pin holes) can be prevented. Furthermore, since the parts do not move up and down, they do not get tangled after being disassembled.

[0026] It is preferable that the component jump-out prevention plate 107 is made of a soft material. As shown in FIG. 4, the thickness of the component jump-out prevention plate 107 is greater than the height of the components. The component jump-out prevention plate 107 is fixed to the outer frame so as not to move in the same manner as the top plate 106. This configuration can prevent the components from jumping out and damage to the components. By fixing the plate to the outer frame, the weight of the parts related to the eccentric movement can be reduced. The weight reduction can also prevent vibration and noise. The jump-out prevention plate 107 fixed to the outer frame surrounds the periphery, and when a tangled component hits it, it applies a different change to the component than two cylinders that move with the top plate 106, thereby breaking up the tangled components. The weight reduction can also prevent wear on the parts related to sliding and the parts in contact with them (such as eccentric pins and pin holes).

[0027] The thickness of the top surface of anti-jump-out plate 107 is such that the edges of top plate 106 are hidden even when top plate 106 is rotated eccentrically. With this configuration, top plate 106 can move eccentrically with the corners always hidden. It also prevents parts from hitting the edges and being damaged. It also prevents fingers, etc. from hitting the edges and getting pinched. In addition, since parts do not protrude from the outer frame, it prevents parts from hitting hands, etc.

[0028] Also, the gap between the component jump-out prevention plate 107 and the top plate 106 is narrower than the thickness of the component. It is installed as low as possible to prevent rubbing against the top plate 106. With this configuration, the components do not enter the gap between the component jump-out prevention plate 107 and the top plate 106, and the occurrence of up and down movement of the top plate 106 during eccentric movement can be suppressed. Also, it is possible to prevent the components from entering the gap between the component jump-out prevention plate 107 and the top plate 106 and being damaged. Also, it is possible to prevent fingers, etc. from entering and being pinched in the gap between the component jump-out prevention plate 107 and the top plate 106. Also, since the components do not protrude from the outer frame, it is possible to prevent them from hitting the hands, etc. Furthermore, by suppressing the occurrence of up and down movement, it is possible to prevent the components once disassembled from becoming entangled again.

[0029] Next, the mechanism for preventing re-entanglement after disassembly will be described. Figure 6 is a diagram for explaining the mechanism for preventing re-entanglement after disassembly.

[0030] In FIG. 6, first, the device is started in an entangled state (S601). The eccentric motion causes the bottommost part in contact with the top plate 106 to move, causing other entangled parts to swing and move (S602).

[0031] Then, the other entangled parts start to come apart (S603). As other parts are also tilted, they are more likely to get caught on the protruding parts (S604).

[0032] Once the parts have been disassembled, they become lighter as individual parts, and the frictional resistance with the top plate 106 also decreases, so that the parts simply slide parallel to the convex shape of the top plate 106 within the rotation range of the eccentric motion (S605).

[0033] Even if the parts collide with each other due to eccentric motion, the ring surfaces only come into contact with each other, and the parts do not become entangled (S606).

[0034] After that, the parts continue to slide over the protrusions of the top plate 106 and do not become entangled with each other (S607).

[0035] In this way, according to the separation device of the first embodiment, the components do not become entangled again, and the components are less likely to be damaged.

[0036] The present invention is not limited to the above embodiment, and can be modified as appropriate without departing from the spirit of the invention. For example, the rotation direction of the eccentric gears 103-1 and 103-2 may be changed between forward and reverse rotation during one cycle of disassembling the parts. With this configuration, even if the entangled parts cannot be disassembled by rotating only in the same direction, the disassembly direction can be changed by rotating in the reverse direction when the parts cannot be disassembled, and the effect on the parts, such as the way the protrusions of the top plate 106 are caught, can be changed, and the entangled parts can be disassembled.
