A spring conveying device 2 and a coil spring supply device 3 for supplying a coil spring to the coil spring conveying device 2 are configured.
[0007]
The coil spring conveying device 2 includes rails 7 and 7 extending horizontally through the spring carry-in port 5 and the spring carry-out port 6 of the cabinet 1, and the rails 7 and 7 extending along the rails 7 and 7. Three rotating rolls 9 and 9 (see FIG. 3) for rotating coil springs placed between and placed horizontally, and coils on the rotating rolls 9 and 9 running on the rails 7 and 7 A plurality of cages 4 and 4 with wheels 33 for accommodating and moving springs, and a cage feeding device 8 which is arranged in the vicinity of the spring inlet 5 of the cabinet 1 and sequentially feeds the cages 4 with wheels 33 onto the rails 7 and 7. And the cage reduction device 10 for returning the cage 4 with the wheels 33 after the coil spring is carried out to the original position. The cage 4 with wheels 33 has a U-shape when viewed from above, and connects the pair of side portions 4a and 4a to which the wheels are mounted and the leading ends of the pair of side portions 4a and 4a. It is comprised with the part 4b.
[0008]
As shown in FIGS. 4 and 5, the cage feeding device 8 includes two endless roller chains 12 having a plurality of locking mechanisms 11 and 11 that can be locked to the protrusions of the cage 4 with the wheels 33. It is composed of two pairs of chain wheels 13, 13, 14, 14 over which two endless roller chains 12, 12 are bridged, and driving means 15 that rotationally drives one chain wheel 14, 14. The driving means 15 includes a motor 16 with a speed reducer, a chain wheel 17 fitted to the rotary shaft 16 fitted with the chain wheel 14 and 14, and a chain wheel 18 fitted to the output shaft of the motor 16 with the speed reducer. The endless roller chain 19 spans the two chain wheels 17 and 18. The two pairs of chain wheels 13, 13, 14, and 14 are attached to the machine base 22 via two rotating shafts 20 and 14 and two pairs of bearings 21 and 21. The motor 16 with a reduction gear is also mounted on the machine base 22.
[0009]
Further, as shown in FIG. 1, the spring supply device 3 is disposed directly above the cage feeding device 8 and circulates between the plurality of spring transport vehicles 23 and 23 and the spring transport vehicles 23 and 23. As shown in FIG. 5, the bottom of the spring transport vehicle 23 is configured to open a double door.
[0010]
Further, as shown in FIG. 1, the cage reduction device 10 includes rails 25 and 25 that extend along and directly below the cage feeding device 8 and the rails 7 and 7, and the rails 7 and 7. Cage lowering mechanism 26 for lowering cage 4 with wheel 33 on the right end of rail 7 to the position of rails 25 and 25, and cage for raising cage 4 with wheel 33 on the left end of rails 25 and 25 to the position of rails 7 and 7 The ascending mechanism 27 and two pairs of upper and lower cylinders 28, 28, 29, and 29 for horizontally moving the cages 4 and 4 with the wheels 33 are configured.
[0011]
In the figure, reference numeral 30 denotes a shot centrifugal projection device, and 31 denotes a shot collecting screw conveyor.
[0012]
Next, a procedure for continuously shot blasting the coil spring W using the equipment configured as described above will be described. First, the endless roller chains 12 and 12 are continuously rotated in the clockwise direction via the two pairs of chain wheels 13, 13, 14, and 14 by driving the motor 16 with a speed reducer of the cage feeding device 8. The cages 4 and 4 with 33 are sequentially fed into the cabinet 1. Moreover, the bottom part of the several spring conveyance vehicles 23 * 23 of the spring supply apparatus 3 is opened sequentially, and the horizontal coil spring W is intermittently inserted in the cage 4 with each wheel 33 on the three rotating rolls 9 * 9. To supply. Along with this, the supplied coil spring W passes through the cabinet 1 so as to be pushed by the cage 4 with the following wheels 33, and while passing through the cabinet 1, It is rotated in the vertical plane by the rotation, and is further sharpened upon receiving a shot from the shot centrifugal projection devices 30 and 30. Thus, the coil spring W that has been cleaned and transferred to the right is pushed out from the right end of the equipment and discharged.
[0013]
On the other hand, the cage 4 with wheels 33 transferred to the right end of the facility is lowered to the position of the rails 25 and 25 by the cage lowering mechanism 26 of the cage reduction device 10, and subsequently sequentially leftward by the cylinders 29 and 29. Transport. The cage 4 with the wheel 33 moved to the left end of the equipment is raised to the position of the rails 7 and 7 by the cage raising mechanism 27 and then sent to the endless roller chains 12 and 12 by the cylinders 28 and 28. By repeating the above operation, the coil spring W can be continuously cleaned.
[0014]
In the above embodiment, the cage 4 with wheels 33 is configured to be moved by being pushed by the cylinders 28, 28. However, as shown in FIG.・ Four wheels 33 and 33 that are engageable with 9 and supported by a support shaft inclined at a required angle with respect to the extending direction of the rotary rolls 9 and 9 are mounted on the lower surface, and the rotary roll 9 -A projecting part that can be loosely inserted between 9 may be formed at the lower end. In this case, the cage 4 with wheels 33 rotates via the wheels 33, 33 as the rotating rolls 9, 9 rotate. The rails 7 and 7 and the cylinders 28 and 28 can be omitted because they travel on the rolls 9 and 9.
[0015]
【The invention's effect】
As is apparent from the above description, the invention of claim 1 is a method for continuously conveying coil springs in an equipment for continuously shot blasting coil springs, wherein the cabinet constituting the polishing chamber is horizontally disposed. Since the coil spring is rotated on the side of the rotating roll extending through, the coil spring rotates, and the coil spring on the rotating roll is moved by a wheeled cage that moves along the rotating roll. The coil springs can be transferred without using a chain conveyor, which makes maintenance much easier and increases the operating rate of equipment compared to this type of device. Excellent practical effect.
