Problems solved by technology

[0007] However, in the conveying device described in the above-mentioned Patent Document 1, since the cam mechanism for changing the peripheral speed of the workpiece holding member includes a plurality of links, the drive plate for supporting the cam mechanism, and the connection between the cam mechanism and the cam mechanism The cam follower is a component composed of various heavy objects such as the flange plate combined with the cam, so the structure is complicated and it is difficult to reduce the cost

Embodiment 1

[0063] Such as figure 1 As shown, the conveying device 1 is installed between the conveyor 2 of the previous process and the conveyor 3 of the subsequent process. In the conveyor 2 of the previous process and the conveyor 3 of the subsequent process, sheet-shaped workpieces 4 such as disposable diapers are conveyed in a state of vacuum suction on a conveyor belt having a plurality of through holes. The transport device 1 receives the workpiece 4 from the conveyor 2 in the preceding process at a predetermined receiving position X, changes the orientation of the workpiece 4, and transfers the workpiece 4 to the conveyor 3 in the succeeding process at a predetermined transfer position Y.

[0064] Such as figure 1 and figure 2 As shown, the conveying device 1 includes a housing 11; a rotating body 20; a plane groove cam body 30 for displacement; a plurality of conveying units 40, and the like. In addition, in figure 1 in, omit figure 2 Among the shown parts, those that are ...

Embodiment 2

[0091] In addition, in the above-mentioned first embodiment, the configuration is as follows: the cam follower 25 for changing direction protruding inward on the inner peripheral surface of the fitting hole 22a of the rotary cylinder 22 and the cam follower 25 formed on the shaft portion 42 are configured as follows: The direction-changing cylindrical cam groove 42a on the outer peripheral surface of the large diameter portion 42b is cam-connected to move the pad 41 in the direction of the normal line L2, and at the same time make the pad 41 rotate around the normal line L2, but the following method can also be used instead of this way, such as Figure 8 (A), Figure 8 As shown in (B), for example, the direction-changing cam follower 146 protruding outward on the outer peripheral surface of the large-diameter portion 142b of the shaft portion 142 and the inner peripheral surface of the fitting hole 122a formed in the rotary cylinder 122 The upper direction-changing cylinder c...

Embodiment 3

[0095] In addition, in the above-mentioned Embodiment 1, the rotational movement of the pad 41 around the normal line L2 caused by the direction-changing cam follower 25 and the direction-changing cylindrical cam groove 42d as the direction-changing member is utilized. 2, the rotational movement of the pad 41 about the normal line L2 caused by the direction-changing cam follower 146 and the direction-changing cylindrical cam groove 122c as the direction-changing member is utilized, but the following method may be used instead of this method ,Such as Figure 9 As shown, a threaded connection between ball screw 242 and nut 222 is utilized, for example. At this time, the ball screw 242 (screw) is fixed to the pad 41 , and the nut 222 is fixed to the rotary cylinder 22 . Then, the ball screw 242 is rotationally driven by, for example, an electric motor 150 such as a stepping motor or a servo motor, and the driving of the electric motor 150 is controlled by the control unit 8 .

Abstract

This conveyance device (1) is provided with a pad (41) (workpiece holding member) that is rotatable about an axis (L1) along with a rotating drum (22) of a rotating body (20). The conveyance device (1) is further provided with: a displacement cam follower (45) that moves the pad (41) within the range of a prescribed distance in a normal line (L2) direction being the radial direction of the rotating drum (22); a displacement flat-surface groove cam body (30) or the like (displacement member); a shaft section (42) that rotates the pad (41) within the range of a prescribed angle about the normalline (L2) along with the movement of the pad (41) in the normal line (L2) direction; and a diversion cam follower (25) or the like (diverting member). The amount of displacement (DeltaP) of the pad (41) outward in the normal line (L2) direction is different at a receiving position (X) where the pad (41) receives the workpiece (4) and at a transfer position (Y) where the workpiece (4) is transferred, and the peripheral speed about the axis (L1) of the pad (41) is set to be different at the receiving position (X) and the transfer position (Y). A conveyance device, which can exhibit the same performance as conventional products while simplifying the structure thereof, is thereby inexpensively provided.

Description

technical field [0001] The invention relates to a conveying device, in particular to a conveying device suitable for conveying sheet-shaped workpieces such as disposable diapers. Background technique [0002] As such a transfer device, as described in Patent Document 1 below, there is known a cam mechanism including a cam mechanism capable of changing the peripheral speeds of a plurality of workpiece holding members. The cam mechanism includes a crank arm, which is held in a freely rotatable manner relative to a drive wheel connected to a rotating shaft; a connecting rod, whose one end is connected to the front end of the crank arm through a pin, and the other end of the connecting rod is connected to the conveying part through a pin. The shift cam roller protruding from the position deviated from the rotation center of the crank arm moves along the shift guide formed on the flange plate. [0003] Existing technical literature [0004] patent documents [0005] Patent Doc...
