The first separation mechanism 12 consists of an edge 14 at the front end of the supply table 11 and a feed roller 15 facing the edge, and the distance between the edge 14 and the roller 15 is formed to such an extent that several stamped objects can fall at the same time. ing. The second separating mechanism 13 is composed of a feed roller 16 and a reversing roller 17, and a spacing adjustment screw 18 sets the spacing between the rollers 16 and 17 to a spacing that allows only one stamped object to pass through. The first separation mechanism 12 separates the paper into a plurality of sheets, and the second separation mechanism further separates the sheets one by one.

A stamp section 20 is provided below the second separation mechanism 13.

This stamping section 20 corresponds to a printing unit 25 and printing rollers 23, 24, which are equipped with two pairs of feed rollers 21a, 21b, 22a, 22b and two printing rollers 23, 24, which sandwich and feed the stamped object. It has platen rollers 26 and 27. And upper feed rollers 21a, 21b
By detecting the object to be stamped by a photoelectric sensor (not shown) provided below, the printing rollers 23 and 24 are rotated so that the stamp is stamped at a predetermined position on the object.

This automatic stamping machine incorporates a stamped object alignment device 30 according to the present invention below the stamping section 20 described above.

This stamped object alignment device 30 has a table 31 whose front end is inserted into a position where the stamped objects fall after being stamped. As shown in FIGS. 3 and 4, this table 31 has rotatable drums 32 and 33 for hanging belts arranged in parallel at the front and rear ends, and three belts hung on both drums 32 and 33 on the top surface of the table 31. belts 34 are arranged, and objects to be stamped are dropped onto each belt 34.

Further, a slit 35 is formed on the top surface of the table 31 at a position between each belt 34, and the slit 35
A screen plate guide rail 36 is provided therein, and a screen plate 37 is erected so as to be slidably supported by this rail 36.

On the other hand, a pushing means 40 is provided at the top of the tip of the table 31 and on the back side of the place where the stamped object falls, for pushing the stamped object toward the screen plate 37 every time it falls. The extrusion means 40 is supported by frames 41, 41 constituting the main body of the automatic stamping machine, and has a drive shaft 44 to which rotation of a motor (not shown) is transmitted via a belt 42 and a pulley 43. . A frame 46 is rotatably suspended from the drive shaft 44 via bearings 45, 45, and a swing shaft 47 is supported by the frame 46 in parallel with the drive shaft 44 via bearings 48, 48. has been done. The rotation of the drive shaft 44 is connected to the swing shaft 47 through gears 49a and 49.
It is made to be transmitted via b.

Two pairs of stamped object extrusion rollers 50 are mounted on the swing shaft 47.
is fixed, and the outer periphery of this roller 50 projects forward from a window 51 formed in the frame 46. Further, the swing shaft 47 is caused to swing by a swing means 52 according to its rotation. Fifth
This figure and FIG. 6 are a main part sectional view and a partial sectional view showing the swinging means 52, respectively.

The swinging means 52 includes a frame 46 whose upper portion is swingably supported on a drive shaft 44 via a bearing 45, and a frame 46.

The swing shaft 47 has the above-mentioned imprinted material extrusion rollers 50, 50 arranged concentrically, and a gear 49a at the end of the shaft.
Eccentric sleeves 53, 53 having circular outer peripheries are fixed at locations corresponding to the swing arms 55, 55.

The swinging arm 55 has a bushing 54 fitted concentrically into a hole on the tip side.
is loosely fitted around the outer periphery of the eccentric sleeve 53,
It is pivotally supported at a predetermined location of the frame 41 in a direction substantially perpendicular to the swing axis 47 via a support pin 56 at the base end, and is swingable about the support pin 56 .

Thus, the swing shaft 47 is rotated by the gears 49a, 49b.
By its own rotation, it rotates at a substantially constant speed while swinging in the front-rear direction, that is, in the direction facing the screen plate 37, within the range of angle α along an arc concentric with the drive shaft 44. As a result, the speed of the outer circumference of the extrusion roller 50 is approximately constant without fluctuation.

Note that at this time, the swing arm 55 is attached to the support pin 56.
It swings up and down by an angle γ with .

The stamped object pushed out by the stamping section 20 is pulled down by the rotation of the extrusion roller 50, and at the same time is pushed out toward the screen plate 37 by its back and forth rocking, and then the stamped object falls. Create a space for objects to fall.

The stamped object alignment device of the automatic stamping machine of the present invention is constructed as described above, and is equipped with a separation mechanism that separates the stamped objects one by one and sends them to the stamping section, thereby ensuring that each stamped object is stamped securely. The extrusion means includes a frame body that is swingable around a drive shaft to which the drive of the motor is transmitted, and a frame body that is supported by the frame body and is swingable around the drive shaft. A swing shaft to which rotation is transmitted, a stamped object extrusion roller fixed concentrically to the swing shaft, and a swing arm that swings freely to support the swing shaft eccentrically at a position near the tip. By providing this, the outer periphery of the extrusion roller maintains a substantially constant speed with no fluctuations, allowing each object to be stamped to be smoothly pulled down one by one after stamping. By swinging in the direction opposite to the screen plate, the effect of hitting the stamped object unlike in the past is eliminated, and moreover, a falling space is accurately formed each time the stamped object falls, so there is no noise, and the stamped object can be easily moved. No more damage to things.
