Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a register stamp printing device that facilitates the replacement of ink rolls.

Conventionally, in a register stamp printing device, a stamp stand drum is placed facing a pressing body, an ink roll is provided so as to circumferentially surround this drum, and a store name, etc. is printed above the stamp stand drum, that is, on the exit side of the printing paper. It has a structure in which a stamp is arranged and a solenoid is connected to the stamp via an arm.

However, in the above structure, parts that drive the stamp, such as an arm and a solenoid, are placed above the ink roll, making the structure complicated, so it is difficult to install and remove the ink roll, which requires frequent replacement, making it difficult to work. There was a bad problem.

The present invention was devised in view of the above, and is a register stamp that simplifies the structure by arranging the solenoid that drives the stamp on the opposite side of the stamp via the ink roll, making it easier to replace the ink roll. The present invention provides a printing device.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the figures, reference numeral 1 denotes a pressing body, the upper end of which is mounted on a shaft 2 and is rotatably supported.

Reference numeral 3 denotes a printing stand drum disposed opposite to the pressing body 1, between which printing paper 4 such as a receipt passes.

Further, an ink roll 5 is provided in circumferential contact with the printing stand drum 3, and both ends of the ink roll 5 are supported by bearing grooves 7 formed in a frame 6.

Further, reference numeral 9 denotes a presser arm, the lower end of which is rotatably attached to the frame 6, and both left and right presser arms 9゜9.
A plate-shaped presser spring 10 is used to elastically press the proximal end side of the
The ink roll 5 is provided with an ink roll 5 supported by the bearing groove 7.
Both ends of the ink roll 5 are pressed from the outside by press arms 9, 9 to prevent the ink roll 5 from coming off.

Further, reference numeral 11 denotes a guide plate provided along the pressing body 1, which guides the printing paper 4 and also serves as a surface for receiving the stamp 12 placed opposite to the guide plate.

The stamp 12 is housed in a stamp case 13, and a stamp holder provided above the ink roll 5 is detachably attached to a stand 14.

This stamp case 13 has a bulge 1 provided on its upper part.
The stamp receiver can be removed from the stand 14 by pulling up the stamp receiver 5.

In addition, the stand 14 of this stamp holder is made of a plate material bent into a rectangular frame shape as shown in FIG.
a, 16b, and 16C are formed, and an oval-shaped support hole 17 is further formed in the top plate 14C.

Reference numeral 18 denotes a base provided below the stand 14, and this base 18 is provided with guide protrusions 19 and 19 along the moving direction of the stamp 12, and stepped pins 18a and 18a are provided on both sides of the guide protrusions 19 and 18. is provided.

The guide protrusion 19.19 fits into a guide groove 16b formed in the center of the bottom plate 14b of the stamp holder 14, so that the stamp holder moves the stamp holder 14 perpendicularly to the printing paper 4. .

In addition, the stepped pins 18a, 18a are connected to the guide grooves 1 on both sides.
6a, 16C, and when the stamp case 13 is removed, the stamp holder reduces the force applied to the stand 14, and also functions to position the stand 14.

Further, 20 is a connecting member formed in the shape of the shaft 2
The stamp arm 22 is rotatably attached to the stamp arm 22 at the top.
It is said that

A stud 23 is provided protruding from the tip side of the stamp arm 22, and this stud 23 is fitted into an oval-shaped support hole 17 formed in the top plate 14C of the stamp holder 14. is supported and receives the weight of this and the stamp case 13 so that no weight is applied to the stamp base 18.

In this case, if the stamp base 18 supports the stamp 12, weight will be added and the operation of the stamp 12 will become unstable.

Further, a solenoid 24 is provided below the ink roll 5, and the tip of this plunger 25 is connected to the lower arm 26 of the connecting member 20.
5 is pressed and compressed, the connecting member 20 rotates about the shaft 21 as a fulcrum.

Further, due to this rotational movement, the rounded end portion 22a of the stamp arm 22 presses the center of the stamp holder 14, that is, the center of the stamp case 13, as shown by arrow F in the figure. .

In the figure, 27 is a coil spring attached to the shaft 21, which functions to return the connecting member 20 and the plunger 25, 28 is a feed roll, 29 is an auxiliary roll arranged opposite to this feed roll 28, Further, numeral 30 indicates a cover that covers the ink roll 5, respectively.

Next, the operation of the apparatus having the above structure will be explained.

The printing paper 54 is guided from below to above through between the feed roll 28 and the auxiliary roll 29, passes between the press body 1 and the stamp stand drum 3, and is then guided between the guide plate 11 and the stamp 1.
It is led between the two.

When a print command to print a store name or the like is given in this state, the solenoid 24 is energized and the plunger 25 contracts.

When the connecting member 20 is rotated in recognition of this, the rounded end portion 22 a of the stamp arm 22 formed on the upper portion of the stamp arm 22 rotates.
The stamp holder presses the center of the front plate 14a of the stand 14,
A stamp 12 integrally attached to this moves forward to print the store name, etc. on the printing paper 4.

In this case, since the stamp holder 14 is guided by a guide protrusion 19 protruding from the base 18, it moves perpendicularly to the printing paper 4, and the pressing force F of the stamp arm 22 is applied to the center of the stamp 12. As a result, the printing of the stamp 12 is clear and has no shading.

Next, the printing stand drum 3 is rotated based on a printing command, and when the pressing body 1 is ejected at a predetermined position, numbers and characters are sequentially printed on the printing paper 4.

If it is necessary to replace the ink roll 5 while using the register in this way, pull up the presser arm 9°9, which is biased by the presser spring 10, and remove the ink roll 5 together with the cover 30 from the bearing. Remove from groove 7.

In this device, since no drive part for the stamp 12 is provided above the ink roll 5, the ink roll 5 can be easily installed, removed, or replaced.

Although the above embodiment shows the configuration in which the printing paper 4 is sent upward, the present invention is not limited to this, and the ink roll 5 and the printing stand drum 3 are arranged vertically, and the stamps 12 are sent to the left and right through these. Alternatively, a solenoid 24 may be arranged to feed the printing paper 4 horizontally.

As explained above, according to the register stamp printing apparatus according to the present invention, the solenoid is placed on the opposite side of the stamp via the ink roll, and the stamp and the solenoid are connected via the connecting member. There is no stamp driving part in the direction in which the ink roll is removed, so the ink roll can be easily replaced, and the structure can be simplified and the device can be made smaller.
