DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic box stamping apparatus for automatically printing characters and figures by pressing gold foil or the like on a box lid or the like.

[0002]

2. Description of the Related Art In general, when printing letters or figures of gold foil on the surface of a box, a stamping device for heating and pressing a gold foil tape is used. In this case, when stamping on the surface of the assembled box, conventionally, the operator has to press the boxes one by one in his hand, and the workability is poor. This is the figure
For example, when stamping on the surface of the lid 1 of a box as shown in FIG. 1, since the lid 1 collapses when it is stacked as it is, the upper and lower lids 1, 1 are alternately shifted and stored in an overlapping manner, so that the transport is automated. This is because it was difficult and the stamps were hand-stamped one by one.

[0003]

SUMMARY OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and automatically transports and stamps a plurality of boxes alternately in a stacked state, thereby enabling automatic work stamping. An apparatus is provided.

A stacker pusher that is provided in the section and adjusts the front end stop position of the box back and forth, is provided along the transport direction of the box, and alternately inclines and raises the box stopped by the stopper. And a stock portion for holding a plurality of boxes stacked alternately and alternately.

Further, in the automatic box stamping device according to the second aspect, the suction portion comprises a suction pipe having a suction pad attached to a lower end thereof, and a lifting bracket for supporting the suction pipe vertically and vertically. It is characterized by the following.

Further, inside the guide rails 39, 39, FIG.
As shown in FIG. 5, two stacking pushers 42A and 42B are provided before and after each other in the transport direction so as to be alternately moved up and down. As shown in FIG. 8, four insertion guide plates 43 formed of spring plates are provided on the outside of the guide rails 39 in an inclined manner, and are vertically moved by a cylinder 44. Also this insertion guide plate
Stacking stopper 45 with a flat upper part adjacent to 43
Are attached at an angle to hold the bottom surfaces of the lids 1 stacked one on top of the other. Alignment pushers 46 are provided on the lower side of the upper stock portion 5 so as to align the front and rear of the stacked lids 1 and 1 so as to be aligned.

[0013] The automatic box stamping device having the above configuration is firstly constructed as shown in FIG.
The lids 1... Stacked alternately and stacked as shown in FIG. 10 are set on the lift 6 of the supply unit 2 as shown in FIG. Next, when a switch (not shown) is turned on, the chain rotates and the lift 6 rises by one lid 1 and stops. Thereafter, as shown in FIG.
Extend and support the suction pipe 15
When the suction pad 16 comes into contact with the upper surface of the uppermost lid 1, the lid 1 is sucked. Next, as shown in FIG. 1, the suction pipe 15 of the suction section 8B is raised first, and the suction pipe 15 of the suction section 8A is raised a little later, and the lid 1 is lifted obliquely. At this time, the suction pipe 15 is
The suction pad 16 at the tip can be tilted at any angle because it is swingably supported.

When the lid 1 is further raised, the second-stage lid 1 connected at the fitting portion is also lifted as shown in FIGS. 6 (A) and 6 (B). In this state, when the separation plates 23, 23 are inserted between the uppermost stage and the second stage lids 1, 1, only the uppermost stage lid 1 is held and separated.
3, 23 retreats. Next, as shown in FIG. 6 (C), when the cylinder 21 operates and the guide rails 22, 22 advance to the width of the lid 1 and the suction portions 8A, 8B are released, the lid 1 is moved to the guide rail. 22, supported on 22. Thereafter, when the feed pusher 25 is operated, the lid 1 is moved to the guide rails 22 and 22.
, And is transported forward while being sandwiched between belt conveyors 28, 28 rotating on both sides of the lid 1.

When the lid 1 is further transported to the stamp section 3 as shown in FIG.
And the belt conveyors 28, 28 stop. Thereafter, the cylinder 30 of the stamp section 3 extends, the press plate 32 descends, and the lower die lifting / lowering section 35 rises, sandwiching the lid 1 from above and below, and the shape of the press plate 32 is stamped by the gold foil ribbon 34. Is done. Thereafter, when the press plate 32 and the lower die lifting / lowering unit 35 return, the belt conveyors 28, 28 rotate again and are transported to the stacking unit 4, and as shown in FIG.
9 and 39 are held. Next, when the distribution kicker 40 operates, the lid 1 slides on the guide rails 39, 39 and hits the distribution stopper 41B at the tip and stops.

At this time, as shown in FIG. 8, insertion guide plates 43 are inserted obliquely inside the both side plates along the transport direction of the lowermost lid 1 on which the stock unit 5 has already been stacked. Have been. In this state, as shown in FIG. 4, the stacking pusher 42A of the stacking unit 4 first rises, and after a short time, the stacking pusher 42B rises to raise the lid 1 obliquely. As a result, as shown in FIG. 9, the side plate of the lid 1 is guided by the insertion guide plates 43 formed of a spring plate,
One side is inserted obliquely inside the upper lid 1. Further, when the stacking pushers 42A, 42B rise and stop, the insertion guide plates 43, 43 are lowered and pulled out, and then the stacking pushers 42A, 42B are lowered, so that the lowermost lid 1 is placed above the stacking stoppers 45, 45. Is held.

When the next lid 1 is lifted by the lift 6 of the supply section 2, the suction sections 8A and 8B are lowered to suck the lid 1, and then the suction section 8A is raised first and the suction section 8A is lifted. 8B rises slightly later. Thereafter, the upper lid 1 similarly separated from the lower lid 1 is sent to the stamp unit 3 and the gold foil ribbon 34
Is stamped. When the next stamped lid 1 arrives at the stacking unit 4, at this time, the sorting stopper 41A is raised as shown by the imaginary line in FIG. 4, and stops slightly before the end. Thereafter, contrary to FIG. 4, the stacking pusher 42B rises first, and the stacking pusher 42A rises a little later and lifts up diagonally. Inserted. When several lids 1 are overlapped in this way, the aligning pushers 46, 46 are operated from both sides to align the front and back of the lids 1 and so as to sequentially stack the lids 1 with the stock unit 5 alternately. It has become.

In the above description, the case where the movable portion is operated by the cylinder has been described. However, a structure in which a motor, a link mechanism, a cam mechanism, and the like are combined may be used. Further, the stamp unit 3 is not limited to a structure in which the ribbon is fed and printed, but may have another printing structure.

[0019]

As described above, according to the automatic box stamping apparatus of the present invention, the lids and the like of boxes stacked alternately and alternately are taken out one by one and supplied to the stamp section to print characters and figures. After that, the lids of the stamped boxes can be automatically stacked by shifting them alternately,
Workability can be greatly improved as compared with the conventional manual operation.
