Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for feeding a colored tape at a fixed pitch for each marking operation in a marking machine that presses a type ring onto a material to be marked through a colored tape.

This type of fixed pitch tape feeding device consists of a feeding roller such as a pressure roller that is placed between the tapes, and a feeding roller that rotates the feeding roller at a predetermined angle intermittently when the bundle that has been pushed down for marking is released and returns. It is separated from the drive means for rotational driving.

In the prior art, this drive means is separated from the gear mechanism, so the structure is extremely complicated because the gears must be changed in order to change the tape feed pitch, and the drive means is always connected to the bundle and the feed roller. Therefore, if the tape is loaded during transportation, the tape will be fed and the tape will be wasted, which is uneconomical.

The purpose of this invention is to provide a marking machine that can change the tape feeding pitch with a simple structure, and also prevents unnecessary tape feeding by disconnecting the bundle from the feeding roller during transportation. An object of the present invention is to provide a fixed pitch tape feeding device.

The embodiments of the present invention will be described in detail with reference to the drawings.
The figure shows a fixed pitch tape feeding device 10 of a marking machine according to the present invention, in which a marking machine 12 is used to print printed characters to be pressed onto a material (not shown) to be marked (for example, an insulated wire) on a pedestal (not shown) via a colored tape 14. A pivot frame 20 with a bundle 18 to which a ring 16 is attached is provided.

This pivot frame 20 is attached to a side plate 24 on a base 22 at a fulcrum 24a.

Note that the colored tape is sent from a tape roll attached to the pivot frame 20 to the feeding device 10 through the marking position.

The fixed pitch tape feeding device 10, as shown in FIG.
A pressure roller 26 and a feeding roller 28 arranged to sandwich the tape 14, and a driving means 3 that rotationally drives the feeding roller 28.
I have been admonishing it since 0.

The shaft 26a of the pressure roller 26 passes through the through hole 27a of the fixed frame 27 of the gantry, and is supported by a spring 29 so as to be pressed against the feed roller 28.
a is rotatably supported by a fixed frame 27 by a bearing.

As shown in FIGS. 1 to 3, the driving means 30 includes a one-way clutch bearing 32 mounted on the shaft 28a of the feed roller 28.
The connection is made up of a swinging rod 34 supported via a swinging rod 34, a connecting arm 36 pivotally supported at the lower end of the pivot frame 20, and a connecting ring 38 attached to the free end of this connecting arm 36. The ring 38 has a through hole 38a through which the swinging rod 34 is relatively slidable.

Therefore, the connecting arm 36 can be connected to a predetermined position of the swinging rod 34 by sliding the connecting ring 38.

The connecting ring 38 is fixed to the swinging rod 34 at a predetermined position by a set screw 40.

In addition, in FIGS. 1 and 2, the reference numeral 34a indicates the swinging rod 34.
, and reference numeral 42 indicates the shaft 28a of the feed roller 28.
Shows the tape insertion knob secured to.

Therefore, when the handle 18 is pressed down for a marking operation, the type ring 16 marks the material to be marked via the colored tape 14, but at this time the pivot frame 20 moves toward the arrow a.
As the connecting arm 36 pivots in the direction, the connecting arm 36 is pulled up, and the swinging rod 34 swings upward about the shaft 28a, so that the enlarged base 34a moves from the stroke of the connecting arm 36 and the shaft 28a, which is the fulcrum, to the swinging rod 34. It rotates in the direction of arrow a' at an angle corresponding to the distance to the connection point.

In this case, since the one-way clutch bearing 32 idles, the feeding roller 28 does not rotate, so the tape 14 is not fed.

Next, when the handle 18 is released, the pivot frame 20 pivots in the direction of the arrow by a spring (not shown), and the connecting arm 36
and its enlarged base 34a via the swinging rod 34 as shown by the arrow b'
1, the feeding roller 28 is rotated to feed the colored tape 14 in the direction of the arrow in FIG.

Note that the rotation angle of the enlarged base 34a at this time is also the same as that of the connecting arm 36.
It is determined by the stroke and the distance from the shaft 28a that supports the swinging rod 34 to the connection point with the swinging rod 34.

Thus, a new tape section reaches the marking position and is used for the next marking operation.

As can be seen from the above, the feeding pitch of the tape 14 is
Determined by the position of 8.

That is, although the swinging angle of the handle 18 and therefore the stroke of the connecting arm 36 is constant, the enlarged base 34 of the swinging rod 34
The rotation angle of a changes depending on the position from the shaft 28a, which is the fulcrum, to the connecting ring 38.

Therefore, as the connecting ring 38 moves to the right on the swinging rod 34, the distance from the shaft 28a, which is the fulcrum, to the connecting ring 38 increases, so the rotation angle of the feeding roller 28 becomes smaller, and conversely, as the connecting ring 38 moves to the left, The rotation angle of the feed roller 28 increases.

Furthermore, during transportation, if the connecting ring 38 is pulled out from the swinging rod 34 and disconnected from the connecting arm 36, the feeding roller 28 will not rotate even when the handle 18 is being carried and the tape will not be fed unnecessarily. It is possible to prevent

According to the present invention, as described above, the tape feeding pitch can be easily changed by simply sliding the connecting ring along the swinging rod and screwing it into a predetermined position, and the structure is extremely simple. It is simple and economical because unnecessary rotation of the feeding roller is prevented by removing the connecting ring from the swinging rod during transportation, and unnecessary feeding of the tape is avoided.
