Furthermore, a paper input tray 20 and an upper conveyance path 3 are provided.
Above A, a paper feed mechanism 30 that also serves as a lid for the upper transport path 3A is arranged so as to cover the upper surfaces of the upper transport path 3A and the paper input cradle 20, respectively. The paper feeding mechanism 30 is pivotally attached to the machine frame 1 at its base end so as to be swingable in the vertical direction.

Further, a stamp mechanism 50 including a stamp drum 52 is disposed above the upper conveyance path 3A near the reversing mechanism 80, and a drive unit 85 including a motor 86 etc. is provided in the machine frame 1 below the lower conveyance path 3B. , a power supply section (not shown) such as a transformer, and a control section 90 are arranged so that the overall weight balance of the machine frame 1, which has a substantially inverted L-shaped side surface shape, is maintained.

As shown in FIGS. 4 and 5, the paper input cradle 20 is placed on the machine frame 1 with the edge of the upper conveyance path 3A slightly downward so that it has a slight inclination with respect to the upper conveyance path 3A. It is arranged between the side plates 2 so that it can be raised and lowered freely by fitting into a guide groove 22 bored in the side plates 2. The raising and lowering is achieved by transmitting the driving force of a motor 23 fixed to the side plates 2 to a gear or the like. The transmission is transmitted to the pinion 25 via the transmission means 24, and the rack 26 that engages with the pinion 25 is fixed to the paper loading pedestal 20. In particular, the lowering is carried out by a clutch using a spring or the like provided in the transmission means 24. This is done by opening 24A and letting it fall under its own weight.

A magnetic synthetic resin sheet 27 is pasted on the top surface of the paper input cradle 20, and a magnetically sensitive metal paper holding piece 28 with an approximately L-shaped cross section is used to hold the sheet. 27, and is formed so that the paper can be clamped and held by the paper clamping pieces 28.

The paper feeding mechanism 30 is pivotally supported by a feed roller 31 disposed above the upper end portion of the upper conveyance path 3A, and a bracket 32 disposed above the upper end portion of the upper conveyance path 3A and pivotally connected to the shaft of the feed roller 31.

The contact pressure of the sheet roller 34 to the paper is made variable by changing the elastic force of the coil spring 39. Therefore, the contact thickness can be selected and set as appropriate depending on the paper thickness, surface roughness, etc., and is designed to ensure reliable conveyance of the paper.

The feed roller 31 is formed of a rubber-like elastic body, and a plurality of circumferential grooves 31A are provided around the circumferential surface thereof. In the circumferential groove 31A, a non-slip member 31B formed in a substantially rectangular parallelepiped shape is fixed at a suitable pitch, and its tip is connected to the circumferential groove 31A.
It is installed outside A. In addition, the tip portions of the anti-slip portions 31B are made to protrude in a direction opposite to the direction of rotation of the feed roller 31 so as to be aligned with each other.

Further, a concave surface having substantially the same curve as the circumferential surface of the feed roller 31 is formed in the portion of the upper conveyance path 3A that contacts the feed roller 31, and a synthetic resin brush body 43 is attached to this concave surface. That is, the combination of the concave surface and the brush body 43 increases the friction between the paper surface and the peripheral surface of the feed roller 31, so that the paper can be reliably drawn in.

Then, the paper feed mechanism 30 feeds only the uppermost paper from the paper input cradle 20 into the machine frame 1, and the paper is stopped by a stopper 70 provided in the upper conveyance path 3A. That is, a paper stopper 70 that can be moved intermittently into and out of the upper transport path 3A is disposed at a portion of the upper transport path 3A before the paper passes the stamp drum 52.

By the way, there is a paper feeding mechanism 30 in the upper conveyance path 3A.
A first paper sensing section 94 and a second paper sensing section 95, each consisting of a light emitting and light receiving diode, are located at two locations, immediately after the feed roller 31 and immediately before the stopper 70.

, an electromagnetic clutch 55 disposed at one shaft end of the stamping shaft 51 , a rotation control section 56 disposed at the other shaft end, and an ink roller 57 that applies ink to the printing plate 53 of the stamping drum 52 . and the paper stopper 70, and is controlled by the rotation control unit 56 so that the stamping shaft 51 rotates once every time one paper passes.

The rotation control unit 56 has locking notches 58A, 5 on the periphery.
A cam plate 58 having a diameter of 8B and formed in a disc shape, a locking pawl 59A that locks into locking notches 58A and 58B of this cam plate 58 at one end, and the other end is connected to a plunger 60A of a solenoid 60. A locking lever 59, whose intermediate portion is pivotally attached to the side plate 2 and whose locking lever 59A is pressed against the periphery of the cam plate 58 by a coil spring 61 fitted onto the plunger 60A, is installed in parallel with the cam plate 58.

The stopper 70, which is operated in conjunction with the rotation control section 56, has its shaft portion 70B mounted between the side plates 2 so that the stopper pawl 70A protrudes at a position immediately before the stamping drum 52 on the upper conveyance path 3A. Then, the stopper claw 7 is always pressed by the coil spring 71.
A lever 72 is fixed to one shaft end, and a plunger 73A of a solenoid 73 is connected to the tip of the lever 72.
By the operation of this solenoid 73, the upper conveyance path 3

In order to forcibly press the conveyance roller 10 only during operation, a presser lever 75 is provided between the side plates 2 with the presser lever 75A pivoted thereon, and the presser lever 75
The shaft end of the stopper 70 is connected to the shaft end of the stopper 70 via a ring 74. Therefore, the paper that is stopped in front of the stamping drum 52 by the stopper 70 is forcibly brought into contact with the transport roller 10 as the presser roller 13 is pressed in the direction of the transport roller 10 as the stopper 70 is released. Therefore, the paper is reliably fed from the inside of the stopper 70 to the stamp drum 52. Immediately after the stopper 70 is activated, the presser roller 13 remains free even if the transport roller 10 rotates, so the paper is not sent forward.

The reversing mechanism 80 has a reversing roller 81 mounted between the side plates 2 so as to be located at the folded portion of the paper conveyance path, and presser rollers 82 that rotate in opposing contact near the upper and lower tops of the reversing roller 81 are disposed, respectively. A guide plate 83 having an arcuate cross section is disposed between the upper and lower pressing rollers 82, 82.

The drive unit 85 has a motor 86 disposed at the bottom of the machine frame 1, and drives the motor 86 to each conveyance roller 1.
0, a paper feeding mechanism 30, a reversing roller 81, and a transmission means 84 for transmitting information to each of the stamping shafts 51.

As shown in FIGS. 3 and 4, the transmission means 87 connects the drive shaft 86A of the motor 86 to the belt 87A.
First, the conveyance roller 10D of the lower conveyance path 3B
is rotated and transmitted from the conveying roller 10D to the conveying roller 10E via the intermediate gear 87B and to the reversing roller 81 via the intermediate gear 87C, and from the reversing roller 81 to the intermediate gears 87D, 87E, 87.

Rotation is transmitted to each of the four.

This transmission means 87 may be used by appropriately selecting transmission nodes such as chains, belts, gears, etc. in consideration of installation space, etc., and is not limited to the illustrated example.
It is sufficient if the speed of the circumferential surface of each stamp drum 52 is the same.

The control unit 90 is composed of electronic components with quick response, and includes a start switch 91, a stop switch 92, a continuous/stop switch 93 provided on the surface of the machine frame 1, and an upper conveyance path 3A immediately after the feed roller 31 and immediately before the stopper 70. On the other hand, the first and second paper sheets each have a light emitting diode and a light receiving diode arranged in the vertical direction.
control units 90 and 95, a sensing unit 63 for detecting the rotational position of the stamping shaft 51, a limit switch 96 for confirming that the sheet roller 34 has contacted the uppermost sheet;
The motor 86 and the motor 2 of the lifting mechanism 21 are connected to a double paper feed sensing section 97 provided as necessary.
3. Electromagnetic clutch 35 and electromagnetic brake 36 of paper feeding mechanism 30, solenoid 73 of stopper 70,
Electromagnetic clutch 55 and locking claw 59A of stamping shaft 51
This is to operate the release solenoid 60 and the like.

That is, by turning on the start switch 91, first the motor 23 of the elevating mechanism 21 is turned on, and the paper loading tray 20 is raised. As the paper rises, the top paper comes into contact with the sheet roller 34, and when it reaches a position where it can be pulled onto the paper transport path, the limit switch 96 is turned on, the motor 86 is activated, and the transport roller 10 is rotated. At the same time, the electromagnetic clutch 35 of the paper feed mechanism 30 is turned on. Therefore, the feed roller 31 and the sheet roller 34 each rotate to draw the paper into the machine frame 1.
The drawn paper is gripped by the first transport roller 10A and blocks the paper first sensing section 94, which turns on the paper and causes the paper feed mechanism 30 to shut off.
The electromagnetic clutch 35 is turned off to stop drawing in the paper. However, since the conveyance roller 10 is rotating, the paper runs on the upper conveyance path 3A, and eventually turns on the second paper sensing section 95 and is stopped by the stopper 70.

When the second sensing section 95 turns on, the electrode clutch 55 of the stamping shaft 51 turns on, and the solenoid 60 of the rotation control section 56 also turns on, and the stamping shaft 51 turns on.
is released from its binding and rotates.

Inside the control unit 90, there is a variable resistor 9 provided in the machine frame 1.
8 forms a timer circuit (not shown) whose set time is freely variable, and after the time set by this timer circuit has elapsed, the solenoid 73 of the stopper 70 is turned ON to release the paper from locking. At the same time, the press roller 13 is forcibly pressed against the conveying roller 10C near the stopper 70, and the paper is sent between the stamp drum 52 and the platen 54 and stamped. The stamped paper is reversed by a reversing mechanism 80 and sent into a stamped paper receiving tray 100 located at the bottom of the machine frame 1 by transport rollers 10D and 10E.

Further, when a paper jam or the like occurs on the upper conveyance path 3A, the paper jam is detected based on the difference in operating time of the first and second sensing sections 94 and 95, and the control section 90 activates the solenoid 60 of the rotation control section 56 and the electromagnetic clutch. 55 is turned OFF, and therefore the locking pawl 59A engages with the locking notch 58B of the cam plate 58, and the stamping shaft 5
1 is stopped mid-rotation. The signal from the sensing section 63 that senses the shielding section 62B of the rotation control section 56 is linked within the control section 90 to generate a continuous operation signal, and if the stamping shaft 51 stops mid-rotation, Said signal is not generated and therefore no continuous operation takes place and the device is stopped.

(Effects of the Invention) Therefore, in the continuous stamping device of the present invention, an appropriate number of conveyance rollers 10 are disposed between the side plates 2 facing each other, so that the paper can be transferred to the upper conveyance path 3A, the folded portion, and the lower conveyance path. 3B is conveyed in the order of paper conveyance path having an approximately U-shaped longitudinal section, and a paper reversing mechanism 80 is disposed at the turning part of this paper conveyance path, and the upper end of the upper conveyance path 3A of the paper conveyance path is formed. A paper input cradle 20 that can be automatically raised as the number of paper decreases is provided in the section.
A paper feed mechanism 30 is provided which is swingably pivoted to the machine frame 1 so as to span over the paper input cradle 20 and the upper conveyance path 3A, and above the upper conveyance path 3A near the reversing mechanism 80. A stamping mechanism 50 is provided with a stamping drum 52 that can be fixed at any position in the axial direction on a stamping shaft 51 that is mounted between the side plates 2, and the paper passes through the stamping drum 52 in the upper conveyance path 3A. A paper stopper 70 that intermittently protrudes into the upper conveyance path 3A is disposed in the front part of the paper feeder, and an operation switch provided on the machine frame 1 controls the paper loading cradle 2.

The feed roller 31 is driven in conjunction with the sheet roller 34 and is disposed above the upper end portion of the upper conveyance path 3A.
is formed of a rubber-like elastic body, and a plurality of circumferential grooves 31A are provided on the circumferential surface of the circumferential groove 31A.
1A, a plurality of anti-slips 31B made of a rubber-like elastic body are arranged at uniform pitches, and the tips of the anti-slips 31B are formed so as to protrude from the circumferential surface of the feed roller 31. A concave surface curved approximately in the same manner as the circumferential surface of the feed roller 31 is formed at the portion of the path 3A that contacts the feed roller 31, and the brush body 43 is attached to this concave surface.
When paper is placed on the paper input cradle 20 and the start switch 91 is turned on, the stamp is automatically stamped in a predetermined position and reversed, and the stamped paper cradle 100 below the paper input cradle 20 is automatically stamped. will be placed in sequence.

In particular, an appropriate number of conveyance rollers 10 are arranged between the opposing side plates 2, so that the paper can be transported through the upper conveyance path 3A,
A sheet conveyance path having an approximately U-shaped longitudinal section is formed, and the sheet is conveyed in the order of the folding section and the lower conveyance path 3B, and a sheet reversing mechanism 80 is disposed at the folding section of this paper conveyance path, which is different from the conventional machine. The overall depth of the device can be halved compared to the previous model, making the device configuration more compact and requiring less installation space.In addition, paper input and stamped paper removal can be installed on the same side, making it easier to use. This makes a good continuous stamping device. Furthermore, when stamping consecutive numbers, etc., the sheets are fed into the stamped paper tray 100 while being inverted by the reversing mechanism 80, and stacked in ascending order of numbers, so that the stamped paper sheets are stacked in ascending order. Handling becomes very easy.

In addition, at the upper end of the upper conveyance path 3A of the paper conveyance path,
A paper input cradle 20 that can be automatically raised as the number of sheets decreases is provided, and this paper input cradle 20
The machine frame 1 is placed so that it covers the upper surface of the upper conveyance path 3A.
Since the paper feed mechanism 30 is pivotally connected to the paper feed mechanism 30, even when the volume of the paper decreases as the stamp is stamped, the paper input cradle 20 rises in response to the change, and the paper feed mechanism 30 paper can be fed with constant pressure. Then, the paper feeding mechanism 30

Since the brush body 43 is attached to this concave surface, the stacked sheets are first shifted in the conveying direction by the sheet roller 34, and then the topmost sheet is surely straightened one by one by the anti-slip 31B of the feed roller 31. This makes it possible to feed paper in a straight line, preventing paper from being fed crooked or fed in multiple sheets overlapping each other, making it difficult for paper jams to occur.

By the way, since the paper feed mechanism 30 is pivotally attached to the machine frame 31 so as to span over the paper input cradle 20 and the upper conveyance path 3A, the paper feed mechanism 30 can be pivoted upwardly. By doing so, even if a paper jam occurs in the paper feed mechanism 30, the
Defective paper can be easily taken out.

Incidentally, above the upper conveyance path 3A in the vicinity of the reversing mechanism 80, a stamping mechanism 50 including a stamping drum 52 that can be fixed at any position in the axial direction on a stamping shaft 51 that is mounted between the side plates 2 is disposed. In the upper conveyance path 3A, before the paper passes the stamp drum 52,
