[0009] [Patent Document 1] JP 2008-150170 A [Patent Document 2] JP 2016-94274 A [Patent Document 3] JP 2011-178511 A [Patent Document 4] Registered Utility Model No. 3050167 [Patent Document 5] Japanese Patent Application Publication No. 8-40522 [Patent Document 6] Patent No. 2900496 [Patent Document 7] Japanese Patent Application Publication No. 5-132122 Summary of the Invention [Problem to be solved by the invention]

[0010] Currently, in order to align O-rings, large-scale devices such as those described in Patent Documents 1 to 7 are required. Small and medium-sized enterprises, in particular, cannot afford large-scale, expensive O-ring alignment devices and are largely dependent on manual labor. Furthermore, small and medium-sized enterprises must also be able to handle small quantities of a wide variety of O-rings, and they believe that nothing beats manual labor.

[0011] In the aligning and feeding device described in Patent Document 1, a delivery groove is formed, and in order to handle a wide variety of O-rings in small quantities, multiple alignment devices are required, resulting in a problem of increased costs. Next, the aligning and conveying device described in Patent Document 2 can untangle O-rings, but cannot align a wide variety of O-rings in small quantities. Furthermore, in the separation device of the parts feeder for supplying O-rings described in Patent Document 3, the delivery port is fixed, and in order to handle a wide variety of O-rings in small quantities, multiple alignment devices are required, resulting in the problem of increased costs.

[0012] In the automatic rubber O-ring transport device described in Patent Document 4, a separation claw is formed, which makes it possible to prevent the transport of multiple O-rings. However, this requires multiple alignment devices to handle small quantities of a wide variety of O-rings of different thicknesses, resulting in the problem of increased costs. Next, the ring-shaped packing supplying method described in Patent Document 5 requires a parts feeder and a belt conveyor, which poses the problem of requiring a vast space. Furthermore, in the component receiver of the vibratory component feeder described in Patent Document 6, a vibrating parts feeder is required, making the device large-scale. Finally, the device for aligning and transferring annular members such as O-rings described in Patent Document 7 also requires a parts feeder, making the device large-scale.

[0013] A primary object of the present invention is to provide a perforated seal part alignment device and a perforated seal part alignment method that are inexpensive enough for even small and medium-sized enterprises to purchase and that can realize the alignment of perforated seal parts. Another object of the present invention is to provide an apparatus and method for aligning perforated seal parts which can align perforated seal parts in a space-saving and inexpensive manner. [Means for solving the problem]

[0014] (1) A perforated seal part alignment device according to one aspect is a perforated seal part alignment device that aligns perforated seal parts, and includes a rotating device, a drum portion having an internal space that is rotated by the rotating device around a horizontal axis or within a range of an acute angle inclination from the horizontal axis, a lifting claw portion provided on the inner surface of the drum portion for lifting the perforated seal part, and a rod-shaped member that receives the perforated seal part lifted by the lifting claw portion.

[0015] In this case, a large number of perforated seal parts are placed inside the drum, and the drum is rotated by a rotating device. The perforated seal parts are lifted by lifting claws provided on the inner circumferential surface of the drum, and when they come into contact with a rod-shaped member, they are dropped so that they are inserted into the rod-shaped member. In other words, there is no need for a parts feeder and / or a conveying unit corresponding to the size of the perforated seal parts. As a result, alignment of the perforated seal parts can be achieved at low cost. Furthermore, even if the type of perforated seal part is changed, alignment of the perforated seal parts can be achieved by changing the diameter of the rod-shaped member and the relative position with respect to the lifting claw part, so alignment of the perforated seal parts can be achieved cheaply and easily.

[0016] (2) A perforated seal part alignment device according to a second aspect of the present invention is a perforated seal part alignment device according to one aspect, wherein the drum portion has a conical or barrel shape sloping downwardly near the center, one or more lifting claw portions are provided near the center of the inner surface of the drum portion, or the inner surface of the drum portion may have one or more stirring protrusions provided on it so that the perforated seal part moves near the center of the inner surface.

[0017] In this case, the one or more stirring protrusions move the perforated seal parts to the center of the drum part and can eliminate the adhesion of the perforated seal parts. Also, since the lifting claw parts for lifting the perforated seal parts are provided in the center of the drum part, the perforated seal parts can be efficiently aligned.

[0018] (3) In the perforated seal part alignment device according to a third aspect of the present invention, it is desirable that the tip of the rod-shaped member is positioned inside the inner circumference of the perforated seal part held by the lifting claw portion.

[0019] In this case, the perforated seal part held by the lifting part is smoothly inserted into the tip of the rod-shaped member.

[0020] (4) In a perforated seal part alignment device according to a fourth aspect of the present invention, it is preferable that the lifting claw portion obliquely projects the perforated seal part onto the tip of the rod-shaped member at an angle in the range of 0 degrees or more and 45 degrees or less from the top of the rotation of the drum portion.

[0021] In this case, by projecting the perforated seal component obliquely, the perforated seal component can be reliably aligned with the tip end of the rod-shaped member.

[0022] (5) A method for aligning perforated seal parts according to another invention is a method for aligning perforated seal parts having a circular or elliptical shape, and includes a rotation step of rotating the perforated seal parts housed in a drum part having an internal space around a horizontal axis or within a range of an acute angle inclination from the horizontal axis, a lifting step of lifting the perforated seal parts using lifting claws provided on the inner surface of the drum part, and a receiving step of receiving the perforated seal parts lifted by the lifting step with a rod-shaped member.

[0023] In this case, a large number of perforated seal parts are placed inside the drum, and the drum is rotated by a rotating device. The perforated seal parts are lifted by lifting claws provided on the inner circumferential surface of the drum, and when they come into contact with a rod-shaped member, they are dropped so that they are inserted into the rod-shaped member. In other words, there is no need for a parts feeder and / or a conveying unit corresponding to the size of the perforated seal parts. As a result, alignment of the perforated seal parts can be achieved at low cost. Furthermore, even if the type of perforated seal part is changed, alignment of the perforated seal parts can be achieved by changing the diameter of the rod-shaped member and the relative position with respect to the lifting claw part, so alignment of the perforated seal parts can be achieved cheaply and easily.

[0024] (A) In the perforated seal part alignment device according to one aspect of the present invention, the lifting claw portion preferably holds 70% or more and 120% or less of the thickness of the perforated seal part at the rotating top of the drum portion.

[0025] In this case, at the rotating top of the drum section, the perforated seal part is easily detached from the lifting claw part, and by coming into contact with the rod-shaped member, the perforated seal part is separated from the lifting claw part and can be aligned with the rod-shaped member. In particular, even if the lifting claw portion is more than 30 degrees from the top, the perforated seal part moves away from the lifting claw portion, and the lifting claw portion can again align the perforated seal part with the rod-shaped member. In addition, since the angle between the movement direction of the lifting claw and the axial direction of the rod-shaped member is about 90 degrees, the perforated seal part can be delivered efficiently. Note that the angle between the movement direction of the lifting claw and the axial direction of the rod-shaped member is preferably 60 degrees or more and 120 degrees or less.

[0026] (B) The perforated seal part alignment device according to the Bth aspect of the present invention is a perforated seal part alignment device according to one aspect, in which the rod-shaped member has a rod shape that is equal to or smaller than the radius of the perforated seal part, and the distance from the lifting claw portion is preferably equal to or larger than 1 / 4 of the diameter of the perforated seal part and equal to or smaller than the radius.

[0027] In this case, since the distance between the rod-shaped member and the lifting claw portion is greater than 1 / 4 the diameter of the perforated seal part and less than the radius, the rod-shaped member can reliably come into contact with the perforated seal part, and the perforated seal part can be handed over to the rod-shaped member.

[0028] The perforated sealing parts include resin packings, resin ring-shaped members, elastic members such as U-packings, V-packings, O-rings, and other perforated members made of any material. [Brief description of the drawings]

[Figure 7] FIG. 11 is a schematic cross-sectional view showing another example of an O-ring alignment device according to another embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. Hereinafter, the present invention will be described in detail.

[0031] [O-ring alignment device 100 according to this embodiment] FIG. 1 is a schematic diagram showing an example of an O-ring alignment device 100 according to this embodiment. In this embodiment, an O-ring is used as an example, but the present invention can be equally applied to resin gaskets, resin ring-shaped members, elastic U-gaskets, V-gaskets, O-rings, and other perforated sealing parts made of any material.

[0032] As shown in FIG. 1, the O-ring alignment device 100 mainly includes a stirring drum unit 200, a rod-shaped alignment jig 500, an electric motor unit 600, and an electric shaft unit 650. The motor unit 600 rotates the stirring drum unit 200 around the axis of the motor shaft unit 650 via the motor shaft unit 650 . At least one side of the stirring drum unit 200 is opened, and a rod-shaped alignment jig 500 is inserted into the inside of the stirring drum unit 200 through the opening. In this embodiment, the rod-shaped alignment jig 500 is illustrated as a rod-shaped member having a uniform diameter, but is not limited to this, and may have a small diameter at the front end and a large diameter at the rear end, and may be not only a column but also a cylinder, a square column, or a square pipe, and any member may be used as long as it can receive and align the O-ring OR. In the case of a square column or a square pipe, the directionality of the alignment can be improved. Furthermore, rod-shaped alignment jig 500 only needs to have rod members that satisfy the above conditions, and may be used in combination with other jigs.

[0033] In this embodiment, the electric motor 600 is a motor. However, it is not limited to a motor, and any rotating device may be used. In particular, the electric motor 600 may be a combination of a motor capable of 50 rotations per minute and a gear head, or a variable speed motor may be used. In this embodiment, the motor unit 600 uses a combination of a 21K6A-A motor manufactured by Oriental Motor Co., Ltd. and a gear head unit 2GN36K.

[0034] Moreover, it is preferable that the stirring drum part 200 has a cylindrical barrel shape and the capacity of the stirring drum part 200 is the total capacity of the O-rings that are the work, that is, a capacity that is 8 to 12 times the input amount. Moreover, it is preferable that the stirring drum part 200 has a conical or barrel shape with an inclined inner surface, and it is preferable that the inner surface is inclined downward toward the location where the lifting claw part 300 is arranged. This makes it easy to move the O-ring OR, which is the workpiece, to the location where the lifting claw portion 300 is disposed.

[0035] Moreover, from the viewpoint of preventing static electricity, it is preferable that the rod-shaped alignment jig 500 is made of metal. Furthermore, it is preferable that the diameter of the tip end of the rod-shaped alignment jig 500 is equal to or greater than ¼ the diameter and equal to or less than the radius of the O-ring to be the work, and it is desirable that the diameter of the rear end of the rod-shaped alignment jig 500 is equal to or greater than the diameter of the O-ring to be the work. As a result, the O-rings can be aligned on the rod-shaped alignment jig 500 efficiently. In this embodiment, since the diameter of the O-ring is φ15, the tip of the rod-shaped alignment jig 500 has a diameter of φ3 mm or more and φ6 mm or less. Furthermore, in this embodiment, even when the diameter of the O-ring was φ25, alignment was possible even though the tip of the rod-shaped alignment jig 500 used had a diameter of φ3 mm or more and φ6 mm or less.

[0036] Next, FIG. 2 is a schematic cross-sectional view showing an example of a partial cross-section of the O-ring alignment device 100 shown in FIG. 1, FIG. 3 is a schematic horizontal cross-sectional view showing an example of the AA cross-section of FIG. 2, and FIG. 4 is a schematic vertical cross-sectional view showing an example of the BB cross-section of FIG. 2.

[0037] FIG. 5 is a schematic diagram for explaining an example of alignment of O-rings OR by the O-ring alignment device 100, and FIG. 6 is a schematic enlarged view for explaining an example of alignment of O-rings OR by the O-ring alignment device 100.

[0038] 2, the stirring drum portion 200 is barrel-shaped and has an internal space formed therein. Furthermore, a large number of O-rings OR of the same type, which serve as workpieces, are accommodated in the internal space. 2 and 3, a plurality of lifting claws 300 are formed on the inner peripheral surface at the center of the stirring drum unit 200. In this embodiment, eight lifting claws 300 are arranged at 45 degree intervals. Note that, although eight are used in this embodiment, the number is not limited to eight, and one, multiple, or any number of claws may be provided. 5, the lifting claw portion 300 is formed of a claw portion 320 and a claw holder portion 340. The claw holder portion 340 is fixed to the inner circumferential surface of the stirring drum portion 200.

[0039] Further, an agitation convex portion 250 is formed on the inner peripheral surface of the agitation drum portion 200. The agitation convex portion 250 is formed to eliminate adhesion of the O-ring OR, which is the workpiece. 2 to 4, in this embodiment, four stirring protrusions 250 are provided on the left, right, top and bottom, but this is not limited to this and one, two, three, four, or any number may be provided. Furthermore, in this embodiment, it is formed of the same material as the stirring drum part 200, but this is not limited to this and any material such as brush, rubber, etc. may be used, or they may be interwoven. As shown in Figure 4, the stirring convex portion 250 formed on the inner surface of the stirring drum portion 200 is angled so that, when rotated, the O-ring OR, which is the workpiece, is gathered in the center of the inner surface of the stirring drum portion 200.

[0040] (O-ring alignment method) As shown in FIG. 3, the stirring drum unit 200 is rotated in the direction of arrow R by the motor unit 600 . In this case, a plurality of O-rings OR housed inside the stirring drum portion 200 are stirred by the stirring convex portion 250. Next, the O-ring OR is lifted up by the lifting claws 300 attached to the inner circumferential surface of the stirring drum 200. In this embodiment, the claw portion 320 of the lifting claw portion 300 has a width of 2 mm to 4 mm and a thickness of 2 mm to 3 mm.

[0041] Next, when the lifting claw portion 300 reaches the top, as shown in Fig. 5, the claw portion 320 of the lifting claw portion 300 is supporting the O-ring OR by 1 mm, so when it comes into contact with the tip of the rod-shaped alignment jig 500, it can drop the O-ring OR towards the rod-shaped alignment jig 500. Note that when the lifting claw portion 300 reaches the top, it is desirable that it supports 70% to 120% of the thickness of the O-ring OR.

[0042] In addition, since the direction in which the lifting claw portion 300 moves and the axial direction of the rod-shaped alignment jig 500 intersect at 90 degrees, the tip of the rod-shaped alignment jig 500 comes into contact with the inner side of the O-ring OR, and as the lifting claw portion 300 moves further, the O-ring OR moves away from the claw portion 320, and the O-ring OR is handed over to the rod-shaped alignment jig 500. Here, a space is formed inside the stirring drum part 200 where the O-rings OR can be individually separated from the group. Also, the O-ring OR moved onto the tangent circumference of the lifting claw part 300 is lifted up, and while the top of the rotation of the stirring drum part 200 is rotated within a range of 0 degrees to 45 degrees, the obliquely projected O-ring OR is brought into contact with the tip of the rod-shaped alignment jig 500, and the O-ring OR is released from the claw part 320 and thrown into the tip of the rod-shaped alignment jig 500, where it is handed over. Also, when the claw portion 320 exceeds the top of the rotation, the O-ring OR may be allowed to freely fall in a predetermined posture due to gravity. In this case, the rod-shaped alignment jig 500 may be adjusted so as to be inserted into the inner diameter of the O-ring OR immediately before the O-ring is allowed to freely fall. As a result, the O-ring OR can be easily aligned on the rod-shaped alignment jig 500.

[0043] Next, an example of the transfer of the O-ring OR will be described as shown in Fig. 6. When the mixing drum part 200 rotates by an angle of Θ1 from the top of the mixing drum part 200, the O-ring OR may be transferred or a method similar to quoit tossing (hereinafter referred to as the quoit tossing method) may be used. 6, in the quoit toss method, the O-ring OR is obliquely projected from the lifting claw portion 300, and while tracing a trajectory, it comes into contact with the tip of the rod-shaped alignment jig 500. The O-ring OR is then inserted into the rod-shaped alignment jig 500 while rotating. In this case, by locating the tip of the rod-shaped alignment jig 500 near the center of the obliquely projected O-ring OR, the O-ring OR can be reliably aligned on the rod-shaped alignment jig 500 through the tip of the rod-shaped alignment jig 500.

[0044] A method of calculating the position of the tip of the specific rod-shaped alignment jig 500 will be described below. First, the O-ring OR to be obliquely projected is positioned at an angle Θ1 rotated from the top of the stirring drum part 200. In this case, the angle Θ1 was set to 20 degrees. Next, the rotational speed of the stirring drum section 200, i.e., the peripheral speed V of the lifting claw section 300, was set to 286 mm / S, the gravitational acceleration G was set to 9.8 m / S (squared), and it was assumed that the O-ring OR contacted the tip of the rod-shaped alignment jig 500 t seconds (t = 0.01) after the oblique projection. Here, the horizontal direction of the desired trajectory of the O-ring OR after being obliquely projected is defined as A and the vertical direction as B.

[0045] In this case, the horizontal trajectory A of the O-ring OR is calculated by A=V*COS(Θ1)t. In addition, the vertical trajectory B of the O-ring OR is calculated by B=V*SIN(Θ1)t-(1 / 2*gt2). As a result, the horizontal trajectory A is A=2.574mm and the vertical trajectory B is B=2.574-0.00049=2.57351mm. Therefore, it is preferable that the tip of the rod-shaped alignment jig 500 is positioned 2.574 mm horizontally and 2.573 mm vertically from the position where the O-ring OR is obliquely projected from the tip of the claw portion 320 of the lifting claw portion 300.

[0046] In this embodiment, a case is described in which the lifting claw portion 300 moves one O-ring OR to the top, but this is not limited to this, and the length of the claw portion 320 may be adjusted so as to move two O-rings OR to the top.

[0047] (Regarding high-mix, low-volume production) FIG. 7 is a schematic cross-sectional view showing another example of an O-ring alignment device 100 according to another embodiment. As shown in Figure 7, even if the type of O-ring OR is changed to an O-ring PR, the O-ring PR can also be easily aligned to the rod-shaped alignment jig 510 by changing the diameter and arrangement of the rod-shaped alignment jig 500 to a rod-shaped alignment jig 510 and / or changing the shape of the claw portion 320 of the lifting claw portion 300 to claw portion 321.

[0048] In this embodiment, the O-ring OR and O-ring PR correspond to the "perforated sealing parts", the O-ring alignment device 100 corresponds to the "perforated sealing part alignment device", at least the electric unit 600 corresponds to the "rotating equipment", the stirring drum unit 200 corresponds to the "drum unit", the lifting claw unit 300 corresponds to the "lifting claw unit", the rod-shaped alignment jig 500 and the rod-shaped alignment jig 510 correspond to the "rod-shaped member", and the stirring protrusion 250 corresponds to the "stirring protrusion".

[0049] Although a preferred embodiment of the present invention is as described above, the present invention is not limited thereto. It is understood that various other embodiments can be made without departing from the spirit and scope of the present invention. Furthermore, although the actions and effects of the configuration of the present invention are described in this embodiment, these actions and effects are merely examples and do not limit the present invention.
