[Industrial applications]

 The present invention relates to a wheel reversing transfer device that transfers wheels while reversing them on conveyors having different heights in a wheel conveying process.

[0002]

[Prior art]

 In wheel manufacturing lines that use conveyors to transfer wheels between processes, the working height is adjusted by providing steps on the conveyors during transfer as necessary. Also, if you want to weld a wheel with the disc surface facing down, and want the disc surface to face up, or conversely, turn the wheel with the disc surface facing up with the disc surface facing downward for inspection of the wheel. If you want, flip the wheels.

[0003] Conventionally, as a method of transferring the wheels onto the conveyors having different heights while reversing the wheels, as shown in FIG. 5, a substantially L-shaped frame body 18 in which the discharge side of the wheels is opened, A wheel receiver 15 formed on the lower surface of the frame body 18 from an open side and an inclined plate 17 arranged downward, and a guide vertically arranged on the open side of the wheel receiver 15. A transfer device is configured with the plate 16, and the wheel sent on the carry-in side conveyor 13 is dropped into the wheel receiver 15 of the transfer device, and the wheel receiver 15 is moved to a predetermined position along the guide plate 16. To raise. When the wheel came off the guide plate 16, the wheel fell down and was inverted by the inclined plate 17 arranged on the lower surface of the wheel receiver 15, and was transferred to the carry-out side conveyor 14 arranged on the exit side.

[0004]

[Problems to be solved by the device]

 In the above conventional technique, the wheel is dropped from the conveyor 13 on the inlet side to the wheel receiver 15 located below the conveyor 13, so that the wheel, the wheel receiver 15, the guide plate 16, or the inclined plate 17 is damaged or damaged. It is easy and moreover, the wheel is laid down on the conveyor 14 on the exit side and transferred, so that there is a problem that the conveyor is damaged or the wheel is scratched. Furthermore, there was a problem that the work environment was poor because of the large noise.

The present invention has been made in order to eliminate the above-mentioned problems, and suppresses noise to improve the working environment, and does not damage the wheel or each device, so that the space is limited. It is an object of the present invention to provide a wheel reversing transfer device that reverses the wheel while changing the height at which the wheel is conveyed.

[0006]

[Means for Solving the Problems]

 The present invention relates to a transfer device in which a wheel is inverted and transferred onto a conveyor having a different height during wheel conveyance, and at least a wheel feeding opening into which the wheel is fed and the wheel feeding opening. A frame with a wheel discharge opening on the opposite side of the wheel, and guide rails on both sides, and a frame on both sides of the wheel discharge opening facing the transfer direction of the wheel. It is composed of a fixed rack arranged, a feed port into which the wheel is fed, a stopper for preventing the wheel from falling, and a reversing box having a plurality of rollers rotatably arranged on the upper and lower surfaces. The shafts provided on both sides of the reversing box are integrally provided with pinions that mesh with the fixed rack, and the guide rail The present invention provides a wheel reversing transfer device having a cylinder that supports a guide block and a bearing that slide with a bearing, and that is connected to the bearing and that moves a reversing box in a vertical direction along a guide rail. .

[0007]

[Action]

 The wheels are sent from the conveyor located on the inlet opening side of the wheel reversing transfer device to the reversing box and roll over the rollers arranged in the reversing box. The pinion fixed to the box moves upward while rotating along the fixed rack, and at the same time, the reversing box rotates half a turn. In this way, the half-turned reversing box reaches the height of the conveyer located on the discharge opening side, and the wheels in the reversing box turn upside down due to the rotation of the reversing box, and Rolls out on the conveyor. When the inside of the reversing box becomes empty, the cylinder rod descends, the reversing box makes a half turn in the opposite direction to the above, and then descends back to its original position, waiting for the next wheel to roll in.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the frame 2 is formed of four columns. The four faces of the frame 2 are open, a wheel feed opening is formed on the wheel entrance side into which the wheel is fed, and a wheel is provided above the facing face of the wheel feed opening. A wheel discharge opening is formed on the wheel exit side where the wheel is sent out. Although each of the openings is formed by opening the entire surface of the frame 2, it is also possible to cover each surface and form the necessary portion.

Fixed racks 3 are arranged and fixed on both sides of the wheel discharge opening of the frame 2 so as to face the wheel transfer direction. Guide rails 11 having guide grooves in the up-down direction are arranged and fixed so as to face each other on both side surfaces of the frame 2.

Further, a reversing box 4 is arranged in the frame 2 so as to be vertically movable by a fixed rack 3 and a cylinder 5. The reversing box 4 has a feed port into which the wheel is fed on one side and a stopper 6 on the opposite side to prevent the wheel from falling, and a plurality of rollers 7 for loading and unloading the wheel are provided on the upper and lower surfaces respectively. As shown in FIG. 3, a pinion 8 that meshes with the fixed rack 3 is integrally fixed to a shaft provided on both sides of the reversing box 4, as shown in FIG. A bearing 9 and a guide block 10 are axially supported via bearings 12 at the ends.

The pinions 8 are arranged so as to mesh with the fixed racks 3, respectively, and the reversing box 4 is rotatably supported by the frame 2 via the pinions 8. At the lowest position, the reversing box 4 is arranged at an angle substantially the same as the inclination angle θ of the carry-in side conveyor 13, as shown in FIG.

As a means for moving the reversing box 4 up and down, cylinders 5 are arranged on both sides of the frame 2, and the wheel reversing transfer device 1 is configured by being connected to the bearings 9.

Further, as shown in FIG. 4, the inclination angle θ of the carry-in side conveyor 13 and the carry-out side conveyor 14 is preferably about 5 ° to 8 °, but may be about 3 ° to 15 °. However, if it is less than 3 degrees, the wheel does not move by its own weight, and if it is more than 15 degrees, the moving speed of the wheel increases, which is dangerous.

Next, the operation of the wheel reversal transfer device 1 configured as described above will be described.

As shown in FIGS. 1 and 2, a wheel W moving on a carry-in side conveyor 13 provided with an inclination θ of 5 degrees rolls into a reversing box 4 arranged with an inclination θ of 5 degrees, and a stopper 6 is provided. When it hits and stops, the passage of the wheel W is detected by a sensor such as a limit switch and a photoelectric sensor, the cylinder 5 is activated, and the cylinder rod rises. As the cylinder rod rises, the pinion 8 fixed to the reversing box 4 moves upward while rotating along the fixed rack 3, and at the same time, the reversing box 4 makes a half rotation while rising. In this way, the reversing box 4 half-turned reaches the height of the carry-out side conveyor 14 arranged on the discharge opening side, and the wheel W in the reversing box 4 is turned upside down by the rotation of the reversing box 4, Rolls out from the reverse box 4 onto the conveyor 14 on the unloading side. When the inside of the reversing box 4 becomes empty, the cylinder rod descends in response to the signal that the passage of the wheel W is detected by a sensor such as a limit switch and a photoelectric sensor, and the reversing box 4 rotates halfway in the opposite direction and descends. Then return to the original position and wait until the next wheel rolls in.

In the above embodiment, the cylinder 5 is operated by hydraulic pressure, pneumatic pressure, etc., but pressure supply means such as a hydraulic pump and an air compressor are omitted.

Further, although the reverse transfer method from the low place to the high place is shown in the above embodiment, the reverse transfer from the high place to the low place is also possible.

[0019]

[Effect of device]

 With the above configuration, the present invention allows the wheel to be smoothly put in and taken out of the reversing box without being dropped or knocked down, so that the conveyor can be prevented from being damaged and the wheel can be prevented from being scratched. The transfer height of the wheel can be changed in the space, and at the same time, the wheel can be reversed and transferred, which has an excellent practical effect.
