In this way, the auxiliary crank 11.12 is connected to cranks 4 and 5.
Since it is attached to gears 6 and 7 by changing the rotation angle,
It functions to determine the direction of rotation when the position of node 1 is at the mutual consideration point of cranks 4 and 5.

The second section 13 is a plate of substantially the same type as the above-mentioned section 1, and is equipped with a holder 15 on which a type support rubber 14 is attached at a position facing the type 2.

The second joint 13 connects two cranks 16.17 to the center portions 20.21 of the two gears 18.19 at both ends thereof, so as to be arranged parallel to the second joint 1. It is rotatably connected to.

The auxiliary joint 22 is a plate of the same type as the auxiliary joint 10, is arranged parallel to the second joint 13, and is connected to the gear 18.1.
Two auxiliary cranks 23.24, which are connected to the central portion 20.21 of the crank 16.17 at different angles, are rotatably connected to both ends thereof.

In this way, the auxiliary crank 11.12 is connected to the crank 16
．． 17 is attached to the gears 18 and 19 with different rotation angles, so that it functions to determine the direction of rotation when the second joint 13 is at the relative point of the cranks 16 and 17.

The drive gear 25 meshes with the gear 19 and drives the gear 19, and also drives the gear 7 via the idler gear 26.

The idler gear 26 transmits a rotational force opposite to that of the gear 19 to the gear 7.

The printing printer tape 27 is attached to the type 2 and the type support rubber 14.
It is wound around a supply reel 28 so as to travel between the two, and is wound around a take-up reel 29.

After the printing type 2 and the type support rubber 14 are polymerized, the printing printer tape 27 is transferred to the supply reel 28 by a predetermined width.
A drive device (not shown) can be adjusted according to the size of the type 2 so that the type 2 is unrolled from the outside.

The operation of this printing machine A will be explained.

First, when the gear 19 is driven by the drive gear 25, the crank 17 and the auxiliary crank 24 rotate with the rotation of the gear 19, and the crank 16 and the auxiliary crank 23 rotate via the second joint 13 and the auxiliary joint 22. do.

At the same time, the idler gear 26 is driven by the drive gear 25, the gear 7 rotates, and along with this rotation, the crank 5
and the auxiliary crank 12 rotates, and the - node 1 and the auxiliary node 1
0, the crank 4 and the auxiliary crank 11 rotate.

In this way, the type 2 attached to the second node 1 via the holder 3 and the type support rubber 14 attached to the second node 13 via the holder 15 are attached to each crank 4, 5, 16, 17.
Draw a rotation locus with the same radius as .

At this time, the same rotational motion can be obtained no matter which point on the plane of the tip of the type character 2 or any point on the plane of the tip of the type support rubber 14.

Therefore, the interval between the rotating first section 1 and the second section 13 is adjusted so that the type 2 and the type support rubber 14 overlap at the position where the rotating second section 1 and the second section 13 are closest to each other. At the same time, if the object is supplied in accordance with the speed of superimposition and separation of the second section 1 and the second section 13, the printed characters 2 can be lowered perpendicularly to the desired surface of the object and stamped.

The typeface 2 is engraved with arbitrary patterns, characters, figures, etc. to be printed on the lower surface, has a handle on the side for easy insertion and removal, and has a protrusion with a substantially trapezoidal cross section on the upper surface.

The holder 3 on which the type 2 is attached has a notch on the bottom surface that matches the protrusion in order to attach the protrusion on the upper surface of the type 2, and to prevent the type 2 attached to the side from falling off during use. A stopper is provided.

Further, the type 2 is connected to a heating mechanism so that it can be printed on the ear 30' of the subject 30 via a burn-on printer tape 27.

2 and 3 show the present invention in which this printing machine A is combined with a conveyor 31 and a guide mechanism B. The conveyor 31 is installed on a stand 42, and the printing machine A is installed on the rear side of the conveyor 31. is installed on.

The guide mechanism B installed on the conveyor 31 includes guides 32 and 35 provided on both sides of the conveyor 31 in the longitudinal direction.
and a movable piece 34 that changes the course of the carried object 30 in the direction of one guide 32, and a movable piece 34 located next to the movable piece 34,
It is comprised of a movable plate 33 whose distance from the guide 32 can be adjusted according to the size of the subject 30 and which restricts movement of the subject 30 outside the direction of movement.

To explain this guide mechanism B in detail, the type 2 and the type support rubber 1
A guide 32 is arranged on the side of the conveyor 31 so that the ear 30' of the subject 30 is between the guide 32 and the movable plate 33 so that the distance corresponding to the width of the subject 30 is set from the side of the conveyor 31. Protruding and movable.

Further, in front of the movable plate 33, a movable piece 34 is provided for changing the course of the subject 30 carried on the conveyor 31 toward the printing machine A.

The movable piece 34 has a negative end movably pivoted on the outer side of the guide 35 of the conveyor 31, and the other end of the movable piece 34
A rod 37 is connected to a mounting portion 36 movably supported on the outer side of the guide 35, and the length of the rod 37 can be adjusted depending on the size of the subject 30 to set a necessary course change angle.

Furthermore, the movable plate 33 has two rods 38 and 39, which are connected to mounting portions 40 and 41 provided on the outer side of the guide 35 of the conveyor 31. The guide 32 can be approached or moved away from it.

The movable plate 33 includes the type 2 and the type bone rubber 1.
A detection unit 43 such as a limit switch or a phototube is provided on the entrance side of 4 to notify the printing machine A of the entry of the subject 30.
It is set to work.

The object 30 flowing on the conveyor 31 is placed on the movable plate 3 along the way.
4 toward the direction of the printing machine A, and then pushed by the movable plate 33 so that the ears of the subject 30 can pass between the type 2 and the type bone rubber 14, and the subject 30 moves between the guide 32 and the movable plate 3.
3, it is conveyed along the flow direction while being regulated on both sides.

The detection unit 43 detects that the subject 30 approaches,
When the clutch inside printing machine A is activated, printing operation begins.

Then, the speeds of the type 2, the type bone rubber 14, and the conveyor 31 are set in advance so that when the subject 30 passes between the type 2 and the type bone rubber 14, the type 2 can imprint the ear 30' of the subject 30. Since it is adjusted, the ear 3 of the subject 30
Immediately before 0' enters between the type 2 and the type bone rubber 14, the type 2 and the type bone rubber 14 begin to approach each other, and the type 2 and the type bone rubber 14 approach perpendicularly to the subject 30.
When the printing type 2 and the printing type bone rubber 14 come to a position where they overlap,
The ear 30' of the subject 30 is held with equal force by the type 2 and the type bone rubber 14, and at the same time is stamped by the type 2, and then carried out of the conveyor 31.

In the above embodiment, a container packed with tofu was described as the subject 30, but the present invention is not limited to this, and any type of sealed pack may be used as long as it has an ear 30'.

As described above, the printing device according to the present invention uses a printing machine in which the type 2 and the type bone rubber 14 are vertically approached and separated from each other perpendicularly to the surface of the subject 30 by the movement of two pairs of upper and lower cranks. Type 2 can be a flat type, and if you want to make a mark where the length of the subject is the same as with a conventional rotary printing machine, you can attach the type around the rotating body or make the type fan-shaped. It is no longer needed at all, and
It is possible to imprint a wide area in both the longitudinal and width directions, and of course it is possible to imprint on a moving subject like the rotary type.Furthermore, since the time that the type 2 and the type bone rubber 14 are in contact for a short time, it is possible to imprint on a moving subject.
There is little deviation due to the difference between the speed of
Object 30 whose distance is wide and the shape is not good
The press of the type 2 and the type bone rubber 14 is smooth, and the pressure when the type 2 and the type bone rubber 14 overlap is strong, so it is possible to stamp the object 30 under relatively bad conditions.
Since the vertical movement with the conveyor 31 and the speed with the conveyor 31 can be synchronized,
The object 30 can be automatically stamped while flowing without stopping the object 30 with a stopper or the like, and the object 30 is conveyed on a conveyor without damaging even a soft object.
are regulated to flow sequentially in a predetermined direction by a preset guide mechanism B, so even if the objects 30 are supplied at random, they can be guided to the printing machine A while being individually aligned. Since B can be moved according to the size of the subject 30, it has the advantage of being able to cope with changes in the size of the subject 30.
