[0001]
[Industrial application fields]
The present invention relates to an automatic ticketing apparatus using a continuous medium, particularly a roll-shaped continuous medium.
[0002]
[Prior art]
FIG. 2 is a schematic side view showing the prior art of this type of automatic ticketing apparatus.
In the figure, 1 is a continuous medium, 1 'is a roll of medium 1, 2 is a loading section for loading the roll 1', 10 is a printing section for printing on the medium, and the printing section 10 is a thermal head 4 , A platen 5 and an ink ribbon 6. 7 is a cutter as a cutting means for cutting the printed medium 1 to a predetermined length, 8 is a discharge roll for discharging the cut medium, 9 is a discharge port, and 3 and 3 'convey the medium to these parts. At the same time, it is a feed roller as a conveying means for feeding the front end of the medium back to the standby position.
[0003]
Here, in order to print on the medium 1, the feed rollers 3 and 3 ′ are driven by a driving source such as a motor (not shown) to draw out and convey the medium from the roll 1 ′. Therefore, it takes time to start the conveyance. For this reason, the following mechanism is provided for smoothly supplying the medium length corresponding to the start-up time to the transport system.
[0004]
That is, 31 is a tension arm, which gives the medium supplied from the roll a sag for the length of the start-up time of the supply of the roll and gives tension to the sag. Reference numeral 32 denotes a tension spring. The tension spring 32 pulls the tension arm 31 and resets it to the return position, and applies an appropriate tension to the tension arm 31.
[0005]
Reference numeral 23 denotes a medium cueing sensor, and reference numeral 24 denotes a standby position finding sensor, which are provided on the traveling path of the medium.
The operation of the conventional example having the above configuration will be described.
First, an initial command is issued by a control unit (not shown), whereby the medium 1 is transported to the standby position sensor 23 by the feed roller 3 and waits until a ticketing command is issued.
[0006]
Next, when a ticket issuing command is issued, the medium 1 is sent to the printing unit 10 by the feed rollers 3 and 3 '. In the printing unit, the medium cue sensor 23 takes a print timing, and the medium 1 is pressed against the ink ribbon 6 by the thermal head 4 and the platen 5 to perform predetermined printing on the surface.
At this time, the slack held by the tension arm 31 is fed while being given an appropriate tension by the tension spring 32 until the roll supply start-up time, so that the medium 1 can be stably conveyed.
[0007]
Thereafter, the medium 1 is cut into a predetermined length by the cutter 7 and discharged from the discharge port 9 by the discharge roller 8, and a series of ticket issuing operations is completed.
After the ticket issuing operation is completed, a timer (not shown) is monitored, and if there is no next ticket issuing command within a predetermined time, it is determined that the ticket issuing operation is not performed continuously, and the feed rollers 3 and 3 'are driven in the reverse direction. Then, the front end of the cut medium 1 is retracted to the standby position detection sensor 24.
[0008]
At this time, the tension arm 31 is reset to the return position by the tension of the tension spring 32.
[0009]
[Problems to be solved by the invention]
However, according to the prior art having the above-described configuration, the medium is always tensioned via the tension arm regardless of whether the printing is on standby or when the apparatus is stopped. There was a problem that it was easy.
[0010]
In view of the above problems, the present invention obtains a configuration in which the medium is released from the tension from the tension arm when the medium is stopped for a long time, such as when waiting for printing or when the apparatus is stopped, to prevent curling. An object of the present invention is to provide a device that is less likely to cause a jam or the like.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, when a medium is stopped for a long time, the medium is slackened so that the medium does not receive the tension of the tension arm.
That is, the present invention provides a loading unit for loading a roll of continuous medium, a printing unit for printing on a supplied medium, a cutting unit for cutting the printed medium into a predetermined length, and a cut medium. A discharge port for discharging, a transport means for transporting the medium to each of these parts and reversely feeding the front end of the medium to the standby position, and a slack of the start-up time of the supply of the same roll to the medium supplied from the roll In an automatic ticketing apparatus having a tension arm that holds and applies tension to the slack, a return detecting means for detecting the return of the tension arm and a clearance for allowing slack in the medium are provided, and the leading end of the medium is waited by the transport means. In the case of reverse feed to the position, the reverse feed of the transport means is stopped after a predetermined time after the tension arm has completely returned.
[0012]
[Action]
With the above configuration, in the present invention, when the medium front is reversely fed to the standby position by the conveying means, the return detecting means detects the return of the tension arm, and the transport is performed at a predetermined time after the tension arm has completely returned. Since the reverse feed of the means is stopped, the medium is fed into the clearance and a predetermined slack is generated with respect to the tension arm.
[0013]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic side view showing an embodiment of the present invention.
In the figure, 1 is a continuous medium, 1 'is a roll of medium 1, 2 is a loading section for loading the roll 1', 10 is a printing section for printing on the medium, and the printing section 10 is a thermal head 4 , A platen 5 and an ink ribbon 6. 7 is a cutter as a cutting means for cutting the printed medium 1 to a predetermined length, 8 is a discharge roll for discharging the cut medium, 9 is a discharge port, and 3 and 3 'convey the medium to these parts. At the same time, it is a feed roller as a conveying means for feeding the front end of the medium back to the standby position.
[0014]
Reference numeral 31 denotes a tension arm having the same function as that of the prior art. The medium supplied from the roll 1 'has a slack of a length corresponding to the start-up time of the supply of the roll 1' and gives tension to the slack. The tension arm 31 is attracted by the tension spring 32 and reset to the return position as in the conventional case, and is given an appropriate tension.
[0015]
Reference numeral 25 denotes a tension reset sensor as return detection means for detecting the return of the tension arm 31. Reference numeral 33 denotes a clearance provided behind the tension arm 31 so as to allow the slack of the medium.
Reference numeral 23 denotes a medium cueing sensor, and reference numeral 24 denotes a standby position finding sensor, which are provided on the traveling path of the medium.
[0016]
FIG. 2 is an operation flowchart showing the operation of the present embodiment having the above-described configuration. The operation of the present embodiment will be described below with reference to FIG.
First, when an initial command is issued by a control unit (not shown) (S1), the medium 1 is transported to the standby position sensor 24 by the feed roller 3 (S2 to S4), and waits until a ticketing command is issued (S5). ).
[0017]
Next, when a ticket issuing command is issued, the medium 1 is sent to the printing unit 10 by the feed rollers 3 and 3 '(S6). The printing unit 10 takes a printing timing by the medium cue sensor 23, and the medium 1 is pressed against the ink ribbon 6 by the thermal head 4 and the platen 5, and predetermined printing is performed on the surface (S7).
At this time, the slack held by the tension arm 31 as in the conventional case is sent while being given an appropriate tension by the tension spring 32 until the start-up time of the supply of the roll 1 ', so that the medium 1 can be stably conveyed. can get.
[0018]
Thereafter, the medium 1 is cut into a predetermined length by the cutter 7 (S8), and is discharged from the discharge port 9 by the discharge roller 8 (S9), and the series of ticket issuing operations is completed.
After the ticket issuing operation is completed, a timer (not shown) is monitored. If there is no next ticket issuing command within a predetermined time (S10), it is determined that the ticket issuing operation is not performed continuously, and the feed rollers 3 and 3 'are reversed. The front end of the medium 1 cut by driving in the direction is moved back to the standby position detection sensor 24 (S11 to S12).
[0019]
At this time, the tension arm 31 is reset to the return position by the tension of the tension spring 32.
Here, although the tension reset sensor 25 detects the tension arm 31 (S13), it does not stop the rotation of the feed rollers 3 and 3 'immediately but detects a time of several tens of milliseconds to several hundreds of milliseconds. The rotation is stopped (S14 to S15). As a result, the medium is reversely fed to the clearance 33 behind the tension arm 31 to cause a slight slack.
[0020]
At the time of the next printing, the slack behind the tension arm 31 is sent until the start-up time of the supply of the roll 1 ′, and after the medium 1 comes into contact with the tension arm 31, an appropriate tension is applied by the tension spring 32. Therefore, the medium 1 can be stably conveyed.
The backward movement is performed even when the apparatus is stopped. That is, when the power is turned off, the feed rollers 3 and 3 'are reversely rotated for several tens of milliseconds to several hundreds of milliseconds to reversely feed the medium 1 to the clearance 33 behind the tension arm 31 and have a slight sag. After that, turn off the power.
[0021]
【The invention's effect】
