[0016]
Next, the dedicated jig J when the product W is a connecting rod will be described with reference to FIGS. In FIG. 5, the dedicated jig J has a schematic skeleton structure. For this reason, the projection material is projected onto the connecting rod through the gap. In addition, a reflector M2 can be provided on the lower surface of the dedicated jig J. The reflected projection material is projected onto the lower part of the connecting rod by the reflector M2.
[0017]
Further, in FIG. 6, there is a gap S1 between the product W and the vertical bar J1 or the horizontal bar J2 of the dedicated jig J, and the optimum dimensional design is taken into consideration of the carry-in / out performance and projectability of the product. FIG. 7 shows the pinning site P. FIG. 8 is a perspective view of a dedicated jig.
[0018]
Next, a procedure for performing shot pinning by sequentially feeding a plurality of products W · W into the cabinet 1 using the equipment configured as described above will be described. The motor with a speed reducer (not shown) of the driving means 10 of the cart supply means 3 is driven to rotate the endless roller chains 7 and 7 so that the claw members 8 and 8 advance toward the cabinet 1, and the cart is carried out and circulated. Under the state where the means 4 is driven, the lateral cylinder 3C with the arm 3B of the carriage supply means 3 is contracted to supply the carriage 3B on the roller conveyor 3A of the carriage supply means 3 to the endless roller chains 7 and 7 sequentially. Then, the supplied carts 2 and 2 are moved on the rails 6 and 6 so as to be pushed into the cabinet 1 by being pushed by the claw members 8 and 8 as the endless roller chains 7 and 7 rotate.
[0019]
In this case, as shown in FIG. 4, the claw members 8 and 8 are rotated in the clockwise direction as they move toward the cabinet 1, and the tip is moved to the protrusion 2 a of the carriage 2 via the roller R. They are locked and separated after moving a predetermined distance. The above operation is sequentially performed on the plurality of carriages 2 and 2, and the plurality of carriages 2 and 2 are continuously transferred in the cabinet 1 in a continuously connected state.
[0020]
While passing through the cabinet 1, the products W · W on the carts 2 and 2 are shot-pinned by receiving the projection material from the projection devices 11 and 11.
In this shot pinning, as shown in FIGS. 2 and 3, a projection device is provided at an angle of 30 to 60 degrees with respect to the traveling direction of the carriage 2 of the cabinet 1 and projects a projection material from the vertical direction toward the product. From 11 and 11, a projection material is projected. Then, a part of the projected projection material directly shot-pins the product W, and a part of the projected projection material is above and below the product W, and above and below the cabinet 1. After being reflected by the reflecting plate M of the projection material provided on the product W, the product W is shot-pinned. In this way, the shot pinning process can be performed without inverting the product W.
[0021]
At this time, by providing one or a plurality of dedicated jigs J for the product W on the carriage and holding the product W, shot pinning according to the product W can be performed.
[0022]
Further, as shown in FIGS. 5 to 8, when the product W is a connecting rod, the connecting rod is continuously set at a slight interval in a vertical position on the head other than the pinning portion (FIG. 3). In this example, 10 connecting rods are held by one carriage). For this reason, the projection material is directly projected onto the pinning portion P and the play of the product W can be reduced, so that stable pinning quality can be obtained. Further, since the product W is continuously set at a slight interval, the projection time on the product can be lengthened. Furthermore, since many products W can be thrown into the cabinet 1, the inside of the cabinet 1 can be used effectively. In addition, by providing the reflecting plate M2 on the lower surface of the dedicated jig J, the projection material is projected onto the connecting rod through the gap of the dedicated jig J having a schematic skeleton structure (see FIG. 8). By this projection, the projection material reflected by the reflecting plate M2 is projected to the lower part of the connecting rod, and the scale below the connecting rod can be removed simultaneously with the pinning. That is, a gap S1 is provided between the connecting rod and the dedicated jig J, and the connecting rod is received by the lower rod J3 as a receiving portion provided above the lower surface of the dedicated jig J. This connecting rod can remove the scale of the gap and obtain a stable pinning effect.
[0023]
In addition, the projection apparatuses 11 and 11 project from the side inclined by the previous projection, so that the product W is pinned while being slightly inclined, and the scale can be removed.
[0024]
Subsequently, the trolleys 2 and 2 include a roller conveyor 4A with a first drive mechanism, a chain conveyor 4B with a first drive mechanism, a roller conveyor 4C with a second drive mechanism, The chain conveyor 4D with the drive mechanism is returned to the carriage supply means 3 again, and during this time, the product W / W is removed by an operator (not shown) or a robot. As shown in FIG. 3, the carriages 2 and 2 are tilted immediately before the carriage carrying-circulation means 4, and the projection material on the carriage is dropped by the impact of the carriages 2 and 2 colliding with the stopper. It is recovered by the projection material recovery screw conveyor 12 provided at the bottom of the cabinet 1 of the type shot pinning apparatus. For this reason, a working environment improves without taking out a projection material out of a pinning apparatus. Further, the entrances to the cabinet 1 of the carriages 2 and 2 are orthogonal to the transport route, further preventing the shots from being scattered.
