Description

The present invention relates to a method for manufacturing a conical body formed so as to taper from one end in the longitudinal direction toward the other end, and a transfer device thereof.

For vehicles such as automobiles, for example, a bump stopper provided on a shock absorber of a suspension for the purpose of absorbing the impact when the vehicle body sinks, the whole direction from one end to the other end in the longitudinal direction. A conical body formed so as to form a conical shape that gradually tapers is used (for example, Patent Document 1). The bump stopper, which is an example of this conical shape, is formed so as to be elastically compressively deformed in the longitudinal direction from a foamed resin material such as polyurethane resin, and is interposed in the cylinder rod of the hydraulic damper constituting the shock absorber. When the cylinder rod moves into the cylinder due to the sinking of the vehicle body, the longitudinal direction of the bump stopper is compressed to cushion the impact.

A series of manufacturing processes for such a conical body such as a bump stopper is completed by performing post-treatment in a post-molding process such as removal of burrs generated during molding and quality inspection. In order to efficiently perform post-treatment of such a conical shape, it is required to align the molded conical shapes in a certain direction. In such alignment of the conical shapes, the conical bodies may be temporarily stored in a predetermined storage case or the like, and the work may be performed while the operator confirms each one. Such manual work is not highly efficient, and work mistakes are likely to occur. Therefore, as a means for automatically performing such an operation, a picking robot as in Patent Document 2 is used to take out the conical body of the storage case in a predetermined direction while checking the direction with a camera. Further, as another means, the conical shaped bodies are aligned in a predetermined direction by using a parts feeder as in Patent Document 3.

Japanese Patent No. 471235 Japanese Patent No. 5533727 Japanese Unexamined Patent Publication No. 8-2653

However, when the conical body is taken out by using a picking robot as in Patent Document 2, a camera or various sensors are used to identify the posture of the conical body stored in the storage case and the position / height in the case. Etc. are required, and there is a drawback that the equipment cost becomes high. Further, due to physical restrictions such as the size and shape of the hand of the picking robot, it becomes difficult to take out the conical body at the corner of the case, and it is not realistic to align the directions of all the conical bodies. In addition, there is a problem in work efficiency because the picking robot takes out the items one by one. Further, in the case of a parts feeder as in Patent Document 3, since it is difficult to naturally align them in a certain direction, the orientation of the aligned conical bodies is confirmed by a camera, various sensors, etc. as in the case of a picking robot. Conical bodies in incompatible postures need to be recirculated until aligned in the proper posture. For this reason, even when the conical bodies are aligned by the parts feeder, there is a problem that the equipment cost of the camera and the like increases as in the picking robot, and the conical bodies are recirculated until the orientation is completed. There is a problem that the cycle time is extended.

That is, an object of the present invention is to provide a method for manufacturing a conical body and a transfer device thereof, which can be produced by transporting the conical body to a post-molding process in a fixed posture.

That is, in the mold closed state, the molded body 16a of the medium mold 16 is separated from the mold surfaces 12a and 14a of the lower mold 12 and the upper mold 14 and crosses the space formed by the lower mold 12 and the upper mold 14. By extending 16a, a cavity having the same spatial shape as the shape of the conical body 100 is formed in the molding die 10, and the conical body 100 is formed by foaming and hardening the foam raw material in the cavity. It has become like.

Further, as shown in FIG. 1, the transport device 18 transports the conical body 100 stored in the storage portion in an arbitrary (disordered) posture so that the conical body 100 is in a recumbent posture with the longitudinal direction (central axis) facing the transport direction. An aligned transport unit (aligned transport means) 20 that aligns and transports on the (transport path) 24, and a conical body 100 provided on the terminal side of the transport chute 24 in the aligned transport unit 20 and passing through the transport chute 24. It is provided with a rolling support portion (supporting means) 30 that rotatably supports the body, and a posture changing portion 34 that changes the posture of the conical body 100 moved to the rolling support portion 30 from the lying posture to the standing posture. ..

Here, since the conical body 100 may be stored in the storage unit 22 of the aligned transport unit 20 in an arbitrary (disordered) posture, the storage work of the conical body 100 in the aligned transport unit 20 can be extremely simplified. There are advantages that can be done. When feeding by a transfer device such as a belt conveyor, it is preferable to provide a chute member at the end of the transfer device to guide the conical body 100 toward the storage unit 22.

Then, in the support step, the bottom plate of the storage unit 22 is vibrated by the vibrating unit 26 in a state where the conical body 100 is stored in the storage unit 22 of the aligned transportation unit 20, and the patient is in a lying posture or standing up with the longitudinal direction facing the transportation direction. The conical body 100 is conveyed onto the transfer chute 24 through the spiral passage of the alignment transfer unit 20 so as to be aligned in the posture (see FIGS. 1 and 4). When transported to the transport chute 24, the conical body 100 moves so as to slide down in a lying posture or an upright posture due to the inclination of the transport chute 24. Then, as shown in FIG. 3, when the conical body 100 moves with the transport chute 24 in an upright posture, the tip end side of the conical body 100 comes into contact with the contact portion 28b of the movement restricting member 28, whereby the conical shape is formed. The body 100 is tilted on the transport chute 24 to be in a lying position. That is, in the aligned transport unit 20, the conical body is in the recumbent posture of either the first recumbent posture S1 or the second recumbent posture S2 in which either the large diameter portion 102 or the small diameter portion 104 faces the front side in the transport direction. 100 moves from the end of the transport chute 24 to the rolling support portion 30 and supports it.

Then, in the standing step, as shown in FIG. 4, a conical body moved from the end of the transport chute 24 onto the rolling support portion 30 in either the first lying posture S1 or the second lying posture S2. When the detection sensor 42 detects 100, the rolling motion unit 40 moves from the standby position to the pressing position and presses the conical body 100 on the rolling support portion 30 so as to push it out from the side. The conical body 100 rolls on the rolling support portion 30 in an arc. The conical body 100 rolled in an arc on the rolling support portion 30 corresponds to the movement locus of the conical body 100 in the first lying posture S1 and the second lying posture S2. It falls from any of the provided posture conversion units 34 toward the carry-out unit 50. At this time, as shown in FIG. 5, since the small diameter portion 100a side of the conical shape body 100 is supported by the rolling support portion 30 and the large diameter portion 100b side faces the posture changing portion 34, the conical shape body 100 With the small diameter portion 100a side hooked on the rolling support portion 30, the position of the center of gravity of the conical body 100 is located above the opening of the posture conversion unit 34, and the conical body 100 in the recumbent posture changes its posture from the large diameter portion 102 side. The conical body 100 in the standing posture is placed on the carrying-out portion 50 while falling to the portion 34 and changing the posture to the standing posture.

Here, as shown in FIG. 5, when the conical body 100 falls from the posture changing unit 34, it falls through the guide portion 36 provided in the posture changing unit 34. When the conical body 100 moves so as to slide on the auxiliary portion 36a when passing through the guide portion 36, the conical body 100 temporarily changes its posture from the recumbent posture to the inclined inclined posture, and the guide portion 36 (auxiliary). When falling from the lower end of the portion 36a), the posture changes from an inclined posture to an upright posture. In this way, the conical body 100 in the recumbent posture temporarily changes to the tilted posture and then gently changes to the standing posture so that the posture becomes unstable as the body falls. The shape 100 can be stably placed in an upright posture. Further, by providing the posture suppressing portion 36b of the guide portion 36 at a position where the small diameter portion 104 of the conical body 100 can come into contact with the posture changed to the standing posture, the conical shape is provided so as to tilt beyond the standing posture. The body 100 is restricted from changing its posture. In this way, the conical body 100 that has fallen from the posture changing unit 34 passes through the guide unit 36, so that the conical body 100 can be stably placed on the carry-out unit 50 in an upright posture. Then, by repeating the operation of rolling the conical body 100 moved on the rolling support portion 30 so as to draw an arc on the rolling support portion 30, the posture changing unit 34 changes the posture to the standing posture. The conical body 100 is placed on the carry-out portion 50 and sequentially sent to the post-molding process.

As described above, in the method for manufacturing the conical body 100 and the transport device of the present embodiment, the first recumbent posture S1 in which the large diameter portion 102 faces the front side in the transport direction, and the small diameter portion 104 faces the front side in the transport direction. The conical body 100 in any of the lying postures S2 of 2 is rolled so as to draw an arc on the rolling support portion 30, and the rolling support portion 30 supports the small diameter portion 104 side. By falling from the diameter portion 102 side, the conical body 100 can be changed to a constant standing posture even in a state where the first lying posture S1 and the second lying posture S2 are mixed. Therefore, it is not necessary to individually identify the posture of the conical body 100 with a camera or the like, and the conical body 100 can be manufactured by efficiently transporting the conical body 100 at low cost. Then, by aligning the conical bodies 100 stored in the storage unit 22 of the alignment transport unit 20 in a lying position by vibration, the entire amount of the conical body 100 in the storage unit 22 can be transported, such as a picking robot. It is possible to prevent the occurrence of the conical body 100 that cannot be transported as in the case of taking out the conical body 100, and it is possible to continuously align and transport the conical body 100, so that the manufacturing efficiency can be improved. Further, since it is only necessary to make the conical body 100 into the first recumbent posture S1 or the second recumbent posture S2 in which the longitudinal direction faces the transport direction, it is not necessary to monitor the posture of the conical body 100, and the cone is conical. The amount of the shaped body transported per hour can be increased, and the manufacturing efficiency can be improved.

Further, as long as the longitudinal direction is the lying posture facing the transport direction, either the large diameter portion 102 or the small diameter portion 104 may be in a posture facing the front side in the transport direction, so that the selection of the posture of the conical body 100 can be omitted, and the cone can be omitted. It is possible to improve the manufacturing efficiency by increasing the transport amount of the shaped body 100 per hour. Further, by putting the conical body 100 in the upright posture into the lying posture during the transporting process by the transporting chute 24, the large-diameter portion 102 and the small-diameter portion 104 can be in the lying posture facing the front side in the transporting direction. Therefore, there is an advantage that the selection of the posture of the conical body 100 can be further omitted and the amount of transportation of the conical body 100 per hour can be increased.

Further, by providing the guide portion 36 in the posture changing unit 34, it is possible to regulate the tilting of the conical body 100 which has been dropped from the posture changing unit 34 and changed to the standing posture. In this way, by providing the guide portion 36, it is possible to prevent the conical body 100, which has changed from the lying posture to the standing posture in the process of falling from the posture changing portion 34, to fall down and become the lying posture with that momentum. Therefore, it becomes possible to stably change the posture of the conical body 100 that has fallen from the posture changing unit 34 into an upright posture and place it on the carrying-out unit 50.

Further, the rolling support portion 30 is configured to be movable in the X direction and the Y direction, and the posture is set in a direction intersecting the extending direction of the central axis of the conical body 100 at the end of the transport chute 24 in the aligned transport unit 20. By configuring the conversion unit 34 to be movable, the posture conversion unit 34 can be positioned at a position corresponding to the turning radius of the conical body 100 that rolls so as to draw an arc on the rolling support unit 30. That is, by moving the posture changing unit 34, it is possible to convert various types of conical bodies 100 having different turning radii when rolling on the rolling support portion 30 from the lying posture to the standing posture. Further, by making the carry-out part 50 movable according to the movement of the posture change part 34, the conical body 100 that has fallen from the posture change part 34 and changed its posture to the standing posture is surely stabilized in the carry-out part 50. It will be possible to place it.
