Next, an operation mode of the transfer device M of the embodiment will be described. Note that the four rotary arms 14 are already on standby below the cutter 1 at positions along the horizontal direction.
At that position, the contact surface 29 separates the holding surfaces 19 and 22 of the fixed claw 18 and the moving claw 21 from the guide surfaces 20 and 23 from each other.

First, when the four packaged articles W cut by the cutter 1 fall, they are guided by the guide surfaces 20 and 23, respectively, and the lower part of the packaged article W passes between the sandwiching surfaces 19 and 22. Each packaged product W placed on the bottom surface 18a of the fixed claw 18
Will be housed in the holder 17, respectively.

Thereafter, as the rotating shaft 12 rotates, each rotating arm 14 rotates counterclockwise in FIG. 1 to dispose the holding portion 17 directly above the conveyor 5. At that time, when each holding portion 17 separates from the arrangement portion of the cutter 1, the restriction seat 26

To the side, and the seal portion C of each packaged product W has the sandwiching surface 19.2.
It is sandwiched by 2 and held by the holding portion 17. Then, in that state, each packaged product W is transferred to the vicinity above the conveyor 5.

At this time, when the rotating arms 14 rotate in the counterclockwise direction in FIG. 1 about the rotating shaft 12 so as to move the holding portions 17 from near the cutter 1 to above the conveyor 5, respectively. The cylindrical cam portion 15a has a cam groove 15a into which the cam follower 11 is inserted, so that the rotating shaft 12
Slide in the axial direction.

Since each cam groove 15a is formed in such a shape as to separate the respective rotary arms 15 from each other, the respective holding portions 17 are separated from each other and the packaged product W is conveyed by the conveyor 5. Will be transferred to the top.

That is, as shown in FIG. 3, each packaged product W is rotated by the rotary shaft 1 while being held by the respective holding portions 17.
Since they are separated from each other along the axial direction of the rotary shaft 12 while rotating around the center of the rotating shaft 12, the same uniform posture (longitudinal direction of the package B in the longitudinal direction of the conveyor 5 can be obtained only by increasing the mutual separation distance. (Posture) along the transport direction).

Further, when each holding part 17 is placed just above the conveyor 5 past the lowest point, the abutting part 30 placed above the conveyor 5 is inserted into the central hole 27 and the restriction seat 26 is inserted. Abut. Further, each rotating arm 14
1 rotates counterclockwise in FIG. 1, the contact portion 30 resists the urging force of the coil spring 28 and causes the contact surface 30 of the moving claw 21 to grip.
2 is separated from the holding surface 19 of the fixed claw 18. Then, at that time, each packaged product W is placed on the conveyor 5 while sliding on the guide surface 20 and away from the holding unit 17.

Thereafter, each rotating arm 14 rotates in the clockwise direction in FIG. 1 so as to arrange the holding portion 17 below the cutter 1 in order to hold the next packaged product W, and the original position is obtained. (The position shown by the solid line in FIG. 1) is restored.

The moving speed of the holding unit 17 is faster than the carrying speed of the conveyor 5, and since the holding unit 17 rotates until it comes close to the conveyor 5 and then separates, each packaged product W is transferred to the conveyor 5. When returning to the initial position after being placed, there is no risk that the holding unit 17 will catch the packaged product W.

Therefore, in the transfer device M of the embodiment, a plurality of parallel packaged products W cut by the cutter 1 are transferred onto the conveyor 5 in a uniform posture and separated from each other. Therefore, it can be smoothly sent to the next step.

Further, in the embodiment, the holding portion 17 is brought into contact with the left and right sides of the packaged product W on both sides of each holding portion 17 at the position where the holding portion 17 comes closest to the conveyor 5, and the opened holding portion 17 is surely contacted. A regulation plate 31 for removing the packaged product W is arranged. Therefore, each packaged product W can be placed on the conveyor 5 in a more uniform posture.

In the transfer device M of the embodiment, the fixed claw 1
8 and the moving claw 21 that is biased to the fixed claw 18 side and provided with the regulation seat 26 are used to configure the holding portion 17 at the tip of the rotating arm 14 and to abut the contact portion 29 at a predetermined position. Thirty
It is possible to transfer the packaged product W with a simple configuration in which the package W is arranged. Therefore, the structure of the transfer device can be simplified as compared with the conventional case where the packaged product W is suctioned and held. By the way, with the conventional transfer device that sucks and holds a packaged product, not only a mechanism for pressing the suction site against the packaged product,
Various sensors for detecting the position of the suction site, and for adjusting the timing of conduction / blocking between the suction site and suction means such as a suction blower for holding the packaged product or separating the packaged product. Sensor was required, and the configuration was complicated.

Further, in the transfer device M of the embodiment, the seal part C around the packaged product W is gripped and transferred, and the seal part C is constructed by stacking the wrapping paper in a double layer. Therefore, even if it is gripped, it does not cause a scratch that impairs the sealing property of the packaged product W. By the way, if it is a transfer device that sucks and holds a packaged product, a backing plate is arranged on the rear side of the packaged product, so that the packaged product is pressed against the backing plate,
Since the suction part is pressed against the central part of the packaged product, the packaged product may be damaged.

In the embodiment, the transfer device M provided with the holding portion 17 for holding the packaged product W is shown, but it goes without saying that the holding part 17 may be configured to suck and hold the packaged product W. Of course, even in that case, the effects of the present invention can be obtained.

Further, in the embodiment, the cam groove 15a formed in each cylindrical cam portion 15 has a shape in which the respective rotary arms 14 are widened to the left and right sides, but of course, the respective rotary arms 14 are the same. The cam grooves 15a may be configured so as to widen the mutual distance while moving in the direction, and the shape of each cam groove 15a is not limited to the embodiment as long as the rotary arms are separated from each other.
