The first adsorber 23 is in a forwardly inclined position in which the first link 18 is inclined most in the rotational direction (the direction of the arrow) of the first rotor 12 and the cam follower 37 is at one end 35a of the cam groove 35. Then, the standby posture A before taking out the folding box 3 from the magazine 1 is maintained. When the first link 18 swings in the rising direction, the cam follower 37 of the second link 20 moves to the other end 35b of the cam groove 35 and passes through the peak 35c of the cam groove 35. The first adsorbent 23 moves substantially in parallel and approaches the magazine 1 most, and assumes the take-out posture B. At this time, the suction port of the first adsorbent 23 contacts the folding box 3 evenly. Further, when the first link 18 is swung until the first link 18 is in the backward tilted posture,
The cam follower 37 further moves to the other end 35b of the cam groove 35, and the first adsorbent 23 moves in a direction away from the magazine 1 to be in the transport posture C.

As described above, the second link 20 swings in conjunction with the swing of the first link 18, so that the first adsorbent 23 can be moved up and down (approaching or separating from the magazine 1). It becomes possible. In addition, the cam groove 35 of the cam 34 and the cam groove 32a of the fixed cam body 32 provided on the first rotor 12 are each set to a predetermined shape so that the first adsorbent 23 can be moved substantially in parallel. Have been.

In the outer peripheral portion of the first rotor 12 and in the vicinity of each of the first suction means 13, an open box as a raising means for raising and opening the folding box 3 sucked and held by the first adsorbent 23 is provided. An arm 38 is attached. The opening arm 38 swings about a pivot shaft 38a by a cam mechanism (for example, a cam follower provided to roll on the outer periphery serving as the cam surface of the fixed cam 32). ing. A pressing portion 39 is provided at the tip of the opening arm 38, and the pressing portion 39 presses the folding box 3 that is not completely open to open the box 3 in a predetermined shape.

In the box opening assist device 5, a second rotor 40 is rotatably supported by a machine base. The second rotor 40 rotates in a direction opposite to the direction of rotation of the first rotor 12. The second rotor 40 is provided with a second suction means 41 so as to correspond to each of the first suction means 13. In the second suction means 41, an arm 43 to which the second suction body 41a is fixed is supported so as to be swingable about a pivot 44. Each arm 43 is provided with the arm 43
There is provided a cam follower 45 for swinging. The cam follower 45 is engaged with an annular cam groove 46a of a swing cam 46 fixed to the machine base.

The transporting device 6 comprises a plurality of transporting bodies 50 projecting from a circulating chain 48 at predetermined intervals. One of the transporting devices 6 is disposed below the unloading device 9, and in the process in which the opened folding box 3 is transported to the transporting body 50, an object is accommodated in the folding box 3. Later, the lid of the folding box 3 is folded and sealed as appropriate.

Next, an example of use of the above-mentioned device will be described. First, a large number of flat folding boxes 3 are accommodated in the magazine 1 in a stacked manner. Each folding box 3 separates the pieces 3a and 3b to be brought into contact with each other into the unloading device as shown in FIG. 9 and the adsorbents 23, 41 of both the open box assisting device 5
a is folded so that it can be separated while adsorbing.

In the folding box take-out section D, the first adsorbent 23 of the take-out device 9 sucks one of the pieces to be sucked 3a of the folding box 3 housed in the magazine 1 as described above. Specifically, the rotation of the first rotor 12 causes the first adsorbent 23 (see FIG. 5A), which was in the standby posture A, to fold with the first adsorbent 23 when approaching the magazine 1. The first adsorbent body 23 is at a right angle to the box 3 (see FIG. 5B), and the first adsorbent 23 sucks one of the pieces 3a of the folding box 3 in the front row in the take-out posture B (FIG. 6A) And (b)).

Further, since the first adsorbent body 23 retreats in a substantially right angle posture and separates from the magazine 1, the folding box 3 is taken out of the magazine 1 in a uniform state (FIGS. 7A and 7B). reference). That is, when the first adsorbent 23 is taken out of the folding box 3 from the magazine 1, the cam mechanism causes the first adsorbent 23 to move substantially in parallel and perform a retreating movement. The first adsorbent member 23 can reliably take out the folding box 3 without catching the stopper 1a of the magazine 1 and causing a mistake in taking out, and without causing a displacement of the suction position of the folding box 3.

The folding box 3 taken out as shown in FIG.
By the rotation of the first rotor 12 together with the first adsorbent body 23 in the transfer posture C, the sheet is transferred to the folding box opening section E provided with the open box assisting device 5. On the other hand, the second adsorbent 4 of the
1 a approaches the folding box 3 held by the first adsorbent 23 of the take-out device 9. Further, when the second adsorbent 41a adsorbs the other adsorbed piece 3b of the folding box 3 adsorbed by the first adsorbent 23, the second adsorber 41a swings in the direction opposite to the rotation direction with the rotation of the second rotor. The second adsorbent 41a can adsorb for a long time to open the folding box 3.

Further, the second adsorbent 41a of the open box assisting device 5
Is released, and the respective adsorbents 23 and 41 are released.
Since a is separated, the folding box 3 held by the first adsorbent 23 is transported in a slightly opened state. Further, in the folding box raising portion F, the opening arm 38 is swung by the cam mechanism. Piece 3c between 3b
Is forcibly pressed to open the box securely so that the opening shape becomes rectangular, and that state is maintained.

The folded box 3 in the open state is the first rotor 12
And is supplied between the transport bodies 40 of the transport device 6 in the folding box transfer section G. In the process of being conveyed by the unloading device 9, the folding box 3 is once opened by cooperation with the unpacking assisting device 5, and furthermore, the unfolding arm 38.
As a result, the open state is maintained, so that the sheet is transported to the subsequent process by the transport body 40 in a state where the box is securely opened.

It should be noted that immediately before or immediately after the folding box 3 is supplied from the first suction body 23 of the take-out device 9 to the conveyance body 40 of the conveyance device 6, the opening arm 38 returns to the original position. Also,
While the first suction means 13 moves from the folding box transfer section G to the folding box take-out section D, the first adsorbent 23 that has been in the transport posture C returns to the standby posture A. Then, each step of taking out the folding box from the magazine 1 again and supplying it to the transport device 6 is sequentially performed.

The present invention is not limited to the above embodiment. For example, in the present embodiment, it is possible to provide a contact member as in the case of the conventional device. Since the folding box 3 can be more reliably opened, it is not always necessary to provide the opening assistance device 5. In addition, although the case where the unloading device 9 supplies the folding box 3 directly to the transport device 6 has been illustrated, another intermediate transfer device may be provided between the unloading device 9 and the transport device 6. In addition, in the present invention, the specific configuration of each part can be freely changed in design.

[0028]

As described above, the first suction means of the present invention comprises:
A first link rotatably provided to the rotating first rotor by the rotation of the first rotor, a second link rotatably provided to the first link, and a second link attached to the second link. A suction mechanism, and a link mechanism is provided between the second link and the first rotor so that the first adsorbent of the suction head can be moved substantially in parallel with the swing of the first link. As a result, the folding box can be reliably taken out of the magazine at a predetermined position by suction, and the yield can be improved, so that a series of processes from the removal of the folding box to packing can be accelerated. Can be.

Further, second suction means for sucking the other piece to be sucked of the flat folding box held by the first adsorbent of the first suction means to open the folding box, In the case where a box-opening assisting device including a second rotor for rotating the two suction means is provided, there is an additional advantage that the folding box can be reliably opened and supplied to the transport device.
