It is a lamp that lights up when it is found. This controller 22 is connected to the sensor 23f on the turntable.

The emergency switch 22f is a switch used in an emergency. When the emergency switch 22f is pressed, all operations of the seal mounting unit 20 are stopped.

The turntable 23c is a horizontal flat plate fixed to the upper end of the vertical shaft 23d and rotates by the operation of the driving unit. On the upper surface of the turntable 23c, a fixing jig 23e, a sensor 23f, a sensor hub 23h, and a communication module 23k are provided. The fixing jig 23e serves to maintain a constant relative position of the washing machine part 100 to the turntable 23c. A description of the sensor 23f, the sensor hub 23h, and the communication module 23k will be described later.

The support frame 24 is a structure that is fixed to the support die 21 and provides a support force, and supports the first, second, and third linear motors 25, 26, and 29.

The first linear motor 25 has a first linear guide 25a that is horizontally fixed to the upper end of the support frame 24 and a first slider 25b that slides along the first linear guide 25a. . The position of the first slider 25b is controlled by the controller 22.

Further, the second linear motor 26 has a second linear guide 26a and a second slider 26b. The second linear guide 26a is fixed to the first slider 25b, horizontally extends in a direction orthogonal to the first linear guide, and supports the second slider 26b in a slidable manner. The second slider 26b reciprocates by receiving a control signal from the controller 22.

A description of the third linear motor 29 will be described later.

On the other hand, the guide tube 27 is supported by the second slider 26b, and is guided to the seal groove 101 of the washing machine part 100 by passing downward through the sealing member 110 continuously supplied to the external rotor.

The guide tube 27 has an upper tube 27c, a lower tube 27d, and a hinge 27e. The upper tube 27c is a member vertically fixed to the side of the second slider 26b. In addition, the lower tube (27d) is a member connected to the lower end of the upper tube (27c) through the hinge (27e). In particular, the lower end of the lower tube 27d is bent in the moving direction of the washing machine part 100 moving in the direction of an arrow h, as shown in FIG. 4.

The cross-sections of the upper tube 27c and the lower tube 27d having the above configuration have the shape shown in FIG. 5. That is, as shown in FIG. 5, it takes the shape of an approximately rectangular cross-section and provides a guide slit 27b on one side. The fitting protrusion 110a of the sealing member 110 is transferred in a state accommodated in the guide slit 27b. The sealing member 110 is constrained to the guide tube 27 and is not twisted during transport.

The hinge 27e connects the upper tube 27c and the lower tube 27d, and acts to fold the lower tube in the direction of arrow g. For example, the mounting of the sealing member 110 is completed and the washing machine part 100 is rotated in the direction of arrow g to separate it from the turntable 23c. Before rotating the lower tube (27d), the electric spline (29k) must be moved in advance in the direction of the arrow h.

A pressing gear 28 is installed at the lower outlet portion 27g of the lower tube 27d. The pressing gear 28 is a disk-shaped member having a gear tooth formed on an outer circumferential surface thereof, and is connected to the lower tube 27d through a gear shaft 28a. Of course, the lower tube (27d) rotates around the gear shaft (28a).

This pressing gear 28 pulls the seal member 110 passing downward through the guide tube 27 in the direction of arrow k. The seal member 110 supplied from the outside is pulled by the pressing gear 28 and guided to the seal groove 101. In addition, the seal member 110 guided to the seal groove 101 is pressed by the pressing gear 28 and is embedded in the seal groove 101. At this time, the fitting protrusion 110a is inserted and fixed in the fitting hole 103.

Further, the pressing gear driving means serves to rotate the pressing gear 28 in the direction of the arrow m at the same time as pressing the pressing gear 28 to the bottom of the seal groove 101. The pressing gear driving means includes a third linear motor 29, a gear driving motor 29e, an extended polygonal rod 29f, and an electric spline 29k.

The third linear motor 29 includes a third linear guide 29a installed horizontally below the first linear guide 25a in the vertical direction, and a third slider 29b installed to be slidable on the third linear guide. ). The third slider 29b receives a control signal from the controller 22 and slides along the third linear guide 29a.

The gear drive motor 29e is mounted on the third slider 29b and outputs a rotational force. The gear drive motor 29e is also controlled by the controller 22. The extended polygonal rod 29f is a square rod that is directly connected to the drive shaft of the gear drive motor 29e, and rotates the shaft by receiving axial rotation power from the gear drive motor 29e. The extended polygonal rod 29f extends horizontally toward the pressing gear 28.

The electric spline 29k is a mechanical element having a straight extension groove 29n capable of accommodating the extended polygonal rod 29f in the central axis and meshes with the pressing gear 28. The electric spline 29k is capable of adjusting its position along the length direction of the extended polygonal rod in a state in which the extended polygonal rod 29f is accommodated in the extension groove 29n, and the rotational force of the gear driving motor 29e is pressed by the gear 28 ).

In addition, a sealing direction guiding portion 25p is installed on one side of the upper portion of the first linear guide 25a. The sealing direction induction part 25p serves to guide the guide tube 27 by passing the sealing member 110 supplied from the outside, and includes the support bearing 25g, the swivel guide 25f, and the introduction tube 25k. Equipped.

The support bearing 25g supports the swivel guide 25f so that it can axially rotate. The swivel guider 25f has an approximately cylindrical shape and can rotate in both directions based on a vertical axis (Z axis). In addition, a horizontal passage 25m is provided inside the swivel guide 25f. The horizontal passage (25m) is a through hole through which the sealing member 110 passes.

In addition, the introduction tube (25k) is fixed to one side of the swivel guide (25f) and serves to receive the seal member supplied from the outside and guide it to the horizontal passage (25m).

The first and second linear motors 25 and 26 having the above configuration transfer the pressing gear 28 installed in the lower tube 27d in the front and rear left and right directions (X and Y directions) and seal groove 101 ) To drive. The washing machine part 100 travels along the seal groove 101 while rotating one turn according to the rotation of the turntable.

If the seal groove 101 takes the shape of a ring having a certain diameter, it will not be necessary to move the pressing gear 29 in the front and rear, left and right directions, but as shown in FIG. 2, some part of the seal groove 101 Is a straight line and some parts are arc-shaped, so movement in the front and rear, left and right directions is required.

In any case, the sealing member 110 continuously supplied from the outside is filled in the seal groove 101 of the washing machine part 100 while the turntable 23c rotates one round. The operator cuts the seal member 110 so that the ends of the seal member 110 meet inside the seal groove 101. Insertion of the sealing member 110 is completed.

On the other hand, on the upper part of the turntable 23c, it operates after the insertion of the seal member into the seal groove 101 is completed to determine the accuracy of mounting the seal member 110, and includes a plurality of sensors 23f and a sensor hub. 23h), the communication module 23k is installed. The accuracy of mounting means the accuracy of insertion of the fitting protrusion 110a into the fitting hole 103. If the fitting protrusions 110a are completely inserted into all the fitting holes 103, the accuracy of the shovel is high.

The sensor 23f is disposed vertically below the fitting hole 103 of the washing machine component, and is a sensor that determines whether the fitting hole 103 is blocked by the fitting protrusion 110a. The sensor 23f is an optical sensor.

If the fitting hole 103 is not blocked by the fitting protrusion 110a, the light enters, so if the light is detected, it is determined that the fitting protrusion is not properly inserted. In addition, as shown in FIG. 8, if the fitting hole 103 is completely blocked by the fitting protrusion 110a and does not detect light, it is determined that the insertion of the fitting protrusion 110a for the fitting hole 103 is completed normally. do.

The sensor hub 23h is connected to each sensor 23f through a signal transmission line 23g, and receives the content detected by the individual fit sensor. The communication module 23k is connected to the sensor hub and transmits information (information received from each sensor 23f) collected in the sensor hub to the controller 22.

The controller 22 includes a normal notification lamp 22b that lights up when all of the fitting holes 103 are blocked by the fitting protrusions 110a, and an abnormal notification lamp 22c that lights when some of the fitting holes are not blocked by the fitting protrusions. Has. The operator can check the assembly state of the sealing member 110 to the washing machine part 100 that has finished working on the turntable 23c through the normal notification lamp 22b and the abnormal notification lamp 22c.

On the other hand, when the sealing member 110 is mounted through the seal mounting unit 20, the washing machine component 100 in which the sealing member is mounted is transferred to the static electricity removing unit 40. The static electricity removing unit 40 serves to remove static electricity inherent in the washing machine component 100. The reason for removing static electricity is to allow the foreign matter removing unit 60 to more easily remove fine dust attached to the washing machine part 100.

FIG. 10 is a view for explaining the configuration and operation of the static electricity removing unit 40 and the foreign material removing unit 60 shown in FIG. 1, and FIG. 11 is a plan view of the foreign material removing unit 60 of FIG. 10.

As shown, the static electricity removing unit 40 includes a conveyor 41, a high voltage generator 42, a plurality of position holding hoses 43, and an ion emitter 45. The static electricity removing unit 40 irradiates ions to the washing machine component 100 that is transported on the conveyor 41 to remove static electricity inherent in the component 100.

The high voltage generator 42 supplies a high voltage to an antistatic electrode (not shown) to generate ions, and the ion emitter 45 serves as a kind of nozzle for ejecting the generated ions toward the washing machine part 100. . In addition, the position holding hose 43 is, so to speak, a hose having a property of maintaining a bent state when bent, so that the ion emitter 45 faces an optimum position and direction.

Since the above-described static electricity removing unit 40 is a general matter, further description will be omitted. In addition, as the static electricity removing unit, a voltage application type or a self-discharge type may be applied.

The washing machine component 100 passing through the static electricity removing unit 40 enters the foreign material removing unit 60 in a state in which static electricity is removed. The foreign matter removing unit 60 is to remove dust or contaminants attached to the washing machine part 100 and includes a primary processing unit 60A and a secondary processing unit 60B.

The primary processing unit 60A includes a drum case 64, a porous drum 62, a drive unit 63, an air press-in unit 65, and an intake hood 61.

The drum case 64 is a structure that is open to the top and supports the porous drum 62 so as to be rotatable in the direction of an arrow s. In particular, the bottom surface 64b of the drum case 64 is spaced apart from the outer circumferential surface of the porous drum 62. The narrower the gap between the bottom and the outer circumferential surface, the better. This is because it is good to keep the pressure inside the porous drum 62 as high as possible.

The porous drum 62 is a hollow cylindrical member having a predetermined diameter and has a plurality of air holes 62a on its outer circumferential surface, and is supported by the drum case 64 through a support shaft 62b. As shown in FIG. 10, the porous drum 62 rotates in the direction of an arrow s, receives and transfers the washing machine parts 100 that have passed through the conveyor 48, and transfers them to the secondary processing unit 60B.

The washing machine part 100 receives the pressure of the air ejected through the air hole 62a while riding the porous drum 62. The air ejected through the air hole 62a collides with the washing machine part 100 and blows away fine dust or contaminants remaining in the washing machine part 100.

The support shaft 62b rotatably supports the porous drum 62, and as shown in FIG. 11, the two are disconnected from each other. However, the rotation center axes of the two support shafts 62b naturally coincide. The support shaft 62b is fixed to the porous drum 62 by welding or bolting, and the drum case 64 is bearing-supported.

In addition, a driving part 63 is connected to one of the two support shafts 62b. The drive unit 63 includes a drum drive motor 63a, a drive sprocket 63b, a chain 63e, and a driven sprocket 63c.

The drum driving motor 63a is fixed to the outer surface of the drum case 64 and rotates the driving sprocket 63b by power applied from the outside. The driven sprocket 63c is fixed to the end of the support shaft 62b, and is connected to the driving sprocket 63b through a chain 63e. As a result, the porous drum 62 rotates by receiving the rotational force of the drum driving motor 63a.

The air press-in portion 65 supplies air into the porous drum 62 and includes a blower 65a and a filter 65b. The filter 65b is connected to the support shaft 62b through an air supply hose 62c. The air purified while passing through the filter 65b is supplied into the porous drum 62. Reference numeral 62d in FIG. 11 denotes a swivel joint. The swivel joint 62d is a known component that connects the support shaft 62b that rotates axially and the air supply hose 62c that does not axially rotate.

The air guided into the porous drum 62 by the air press-in portion 65 is discharged through the air hole 62a after filling the inside of the porous drum 62. As mentioned above, since the air hole passing through the inside of the drum case 64 among the air holes 62a receives some resistance from the bottom surface of the drum case 64, most of the air is exposed to the upper portion of the air. It is ejected upward through the hole 62a.

In addition, the air blown out to the bottom of the drum case 64 also goes upward along the gap between the outer circumferential surface of the porous drum 62 and the inner circumferential surface of the drum case 64 (since there is no separate hole to escape from the drum case). Erupts. All air supplied by the blower 65a is blown upward and can be applied to the washing machine part 100.

The intake hood 61 is disposed above the porous drum 62 and inhales air blown out from the porous drum 62 and guides it to the outside. It goes without saying that a vacuum pump (not shown) is installed in the duct extending from the intake hood 61.

The washing machine part 100 from which dust or foreign matter is first removed while riding the porous drum 62 slides down the porous inclined plate 47 and enters the secondary processing unit 60B.

The secondary processing unit 60B includes a horizontal base 66a, a transfer shaft 66c, a transfer roll 66e, a disk 66f, a drive unit, an air press-in unit 65, an upward nozzle unit 65e, and an intake hood 61. ).

The horizontal base 66a is a horizontally extended beam, and two are mutually parallel. Further, the transfer shaft 66c is a rotational shaft that is perpendicular to the horizontal stand 66a and supported at both ends so as to be rotatable on the horizontal stand 66a. A plurality of transfer shafts 66c are disposed parallel to each other and spaced apart. In addition, a transfer roll 66e and a disk 66f are fixed to each transfer shaft 66c.

The conveying roll 66e is a roller that moves the washing machine part 100 in the direction of an arrow t. The number of the transfer rolls 66e mounted on the transfer shaft 66c may vary as necessary.

The disk 66f is a disk-shaped member having a constant diameter, and rotates together with the transfer roll 66e to transfer the washing machine part 100. The disk 66f has a larger diameter than the transfer roll 66e, and one or two are applied per one transfer shaft 66c. However, when the length of the transfer shaft 66c is increased, the number of disks applied is naturally increased.

Such a disk 66f serves to swing the washing machine part 100 back and forth, left and right, while being transported. That is to say, the washing machine part 100 moving in the direction of the arrow t is inclined irregularly in the left and right directions and the front and rear directions during movement. As the washing machine part 100 is tilted in this way, air pressure is applied to a portion that has not received air pressure in the primary treatment unit 60A, for example, a groove or a corner portion. Fine dust or foreign matter remaining in grooves or corners is completely removed.

In addition, as shown in Fig. 11, a dual sprocket 68 is fixed to one end of the transfer shaft 66c. The dual sprocket 68 is connected by a chain 69. Accordingly, all the transfer shafts 66c can rotate in the same direction at the same time. In addition, a shaft driving motor 67 is installed at an end of one side of the horizontal stand 66a. A drive sprocket 67a is fixed to the drive shaft of the shaft drive motor 67. The driving sprocket 67a is connected to the dual sprocket 68 through a chain. Eventually, the transfer roll 66e and the disk 66f rotate by the operation of the shaft driving motor 67.

In addition, an upward nozzle portion 65e is disposed under the transfer shaft 66c. The upward nozzle part 65e blows out the air supplied from the air press-in part 65 to the washing machine parts to blow away dust or foreign matter. Foreign matter separated from every corner of the washing machine part 100 is discharged to the outside through the intake hood 61. The washing machine parts from which foreign substances have been removed through the above process are collected and sent to a subsequent assembly line.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical idea of the present invention.
