[Detailed Description of the Invention] The present invention relates to a printing machine that can imprint a mark on a moving subject.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Representative embodiments of the present invention will be described below with reference to the drawings.

The first section 1 is equipped with a holder 3 approximately in the center thereof, to which typefaces 2 can be attached interchangeably, and both ends are rotatably connected to two cranks 4, 5.

The cranks 4, 5 are connected to central portions 8, 9 of two gears 6, 7 arranged at a predetermined interval.

The auxiliary joint 10 is disposed parallel to the first joint 1, and is connected to the cranks 4, 5 at the center portions 8, 9 of the gears 6, 7.
The two auxiliary cranks 11. are connected at different angles.
12 is rotatably connected to both ends thereof.

In this way, the auxiliary crank 11. 12 is crank 4,
5 is attached to the gears 6 and 7 at different angles of rotation, so that it functions to determine the direction of rotation when the first joint 1 is at the relative point of the cranks 4 and 5.

That is, gear 6 is driven by the rotation of gear 7, and when the cranks 4 and 5 come to a mutually important point, gear 6 tries to rotate in the opposite direction to gear 7, but the auxiliary crank 11, 12 and the auxiliary joint 10, the rotational force of the gear 7 is transmitted to the gear 6 via the auxiliary crank 12, the auxiliary joint 10, and the auxiliary crank 11, and the movement of the gear 6 at the point of consideration is The gear 6 is rotated in the same direction as the gear 7, and smooth rotational movement is possible.

The second section 13 is a plate of substantially the same type as the first 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 section 13 is arranged in parallel with the first section 1 at the center part 20. of the two gears 18, 19. 21
Two cranks 16 and 17 are rotatably connected to both ends thereof.

The auxiliary joint 22 is a plate of the same type as the auxiliary joint 10 and is arranged parallel to the second joint 13, and is connected to the gear 18,
The cranks 16, 17 are attached to the central portions 20, 21 of the cranks 19.
and two auxiliary cranks 23. which are connected at different angles.
24 is rotatably connected to both ends thereof.

In this way, the auxiliary crank 23. 24 is crank 1
6 and 17 are gears 18 with different rotation angles. Since it is attached to crank 19, the position of second section 13 is at crank 16, 1.
7. It acts to determine the direction of rotation when at the mutual consideration point.

That is, the gear 18 is driven by the rotation of the gear 19, and the crank 16. 17 When the mutual consideration point is reached, the gear 18 tries to rotate in the opposite direction to the gear 19, but since the auxiliary cranks 23, 24 and the auxiliary joint 22 are provided, the rotation of the gear 19 is prevented. The force is transmitted to the gear 18 via the auxiliary crank 24, the auxiliary joint 22 and the auxiliary crank 23, regulating the movement of the gear 18 at the point of consideration, and
is rotated in the same direction as the gear 19 to enable smooth rotational movement.

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.

Next, the operation of the present invention 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 first section 1 and the auxiliary section 1
0, the crank 4 and the auxiliary crank 11 rotate.

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

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 first section 1 and the second section 13 is adjusted so that the rotating first section 1 and the second section 13 come closest to each other so that the type 2 and the type support rubber 14 overlap. At the same time, if the object is supplied in accordance with the speed of superimposition and separation of the first 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 has arbitrary patterns, characters, figures, etc. to be printed on the lower surface, a handle on the side for easy insertion and removal, and a projection 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.

For example, FIGS. 2 and 3 show the present apparatus combined with a conveyor, in which the conveyor 31 is installed on a stand 42, and the present apparatus A is attached to the rear side of the conveyor 31.

Then, a guide 3 is placed on the side of the conveyor 31 so that the ear 30' of the subject 30 is between the type 2 and the type receiving rubber 14.
A movable plate 33 protrudes from the side of the conveyor 31 so as to be movable at a distance corresponding to the width of the subject 30.

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 in the direction of the apparatus A.

This movable piece 34 has one end connected to a guide 35 of the conveyor 31.
A rod 37 is connected to a mounting portion 36 which is movably supported on the outside of the guide 35 of the conveyor 31, and whose other end is movably supported on the outside of the guide 35 of the conveyor 31. You can adjust the length to set the required course change angle.

Furthermore, the movable plate 33 has two rods 38 and 39, and these rods 38 and 39 are connected to a mounting portion 40 provided on the outer side of the guide 35 of the conveyor 31. 41, and the subject 30
The guide 32 can be brought closer or further away depending on the size of the guide 32.

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

＼ The object 30 flowing on the conveyor 31 is moved toward the apparatus by the movable plate 34 on the way, and then pushed by the movable plate 33 so that the ears of the object 30 can pass between the type 2 and the type support rubber 14. The subject 30 is guided by 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,
The clutch inside this device A is activated and the stamping operation begins.

Then, when the subject 30 passes between the type 2 and the type support rubber 14, the speeds of the type 2, the type support rubber 14, and the conveyor 31 are adjusted so that the print 2 can be imprinted on the ear 30' of the subject 30. Since the adjustment has been made in advance, the type 2 and the type support rubber 14 begin to approach each other immediately before the subject 30's ear 30' comes between the type 2 and the type support rubber 14, and the type 2
And the type support rubber 14 approaches the subject 30 perpendicularly, and when the position where the type 2 and the type support rubber 14 overlap, the edge 30 of the subject 30 is applied with equal force by the type 2 and the type support rubber 14. At the same time as it is supported, it is stamped with 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 edge 3σ.

As described above, in the printing machine according to the present invention, the type 2 and the type support rubber 14 are brought close to each other in the vertical direction perpendicularly to the surface of the subject 30 by the two pairs of upper and lower crank movements without consideration. It has the following effects.

The type 2 may be a flat type, and when printing a mark with the length of the subject moving as the length, as with a conventional rotary printing machine,
There is no need for any processing such as attaching the type around the rotating body or making the type into a fan shape.

In addition, it is possible to imprint a large area in both the longitudinal and width directions, and of course it is possible to imprint a moving subject like the rotary type.

Furthermore, since the type 2 and the type support rubber 14 are in contact for a short time, there is little deviation due to the difference between the speed of the object 30 and the same speed of the crank, and there is no deviation because the object 30 is sandwiched from above and below.

Further, when the type 2 and the type support rubber 14 are separated from each other, the distance between them is wide, so that objects 30 with poor shapes can be pushed in smoothly.

Furthermore, since the pressure applied when the type 2 and the type support rubber 14 are superposed is strong, it is possible to imprint the image on the subject 30 under adverse conditions in terms of specific effectiveness.

In addition, the vertical movement of the type 2 and the type receiving rubber 14 and the conveyor
Since the speed can be synchronized with that of the object 31, the object 30 can be imprinted automatically while flowing without stopping with a stopper or the like, and even a soft object will not be damaged.
