Further, it is sent to the second heating means 50b through the introduction path 23.

  The heating means 50 (the first heating means 50a and the second heating means) heats the overlapping portion between the end portion of the currently fed belt-like sheet LB and the starting end portion of the newly fed belt-like sheet. Activate the adhesive of the thermally active adhesive layer LBk configured on the sheet LB, and connect the end of the currently fed belt-like sheet and the start of the newly fed belt-like sheet, for example The heating wire coil is heated to the fan and the hot air is blown and heated, or the thermal head is heated and moved in the direction of transporting the belt-like sheet or in the opposite direction, and the connection method can be considered. A heating means may be used.

A control system in the belt-like sheet feeding apparatus having the above-described structure is configured as shown in FIG.
A first paper edge detection sensor 40 a and a second paper edge detection sensor 40 b are connected to the control unit 100. The control unit 100 includes a first motor 31, a feed roller 211a, 211b, and a feed roller 231 that serve as a drive source for the feed roller 241 of the feed mechanism 24 in response to detection signals from the paper edge detection sensors 40a, 40b. Drive control of the second motor 32 serving as a drive source of H.232 is performed. The control unit 100 also performs drive control of each of the first heating unit 50a and the second heating unit 50b in accordance with detection signals from the respective sheet edge detection sensors 40a and 40b.

  The control unit 100 executes processing according to the procedure shown in FIG. In the belt-like sheet feeding device, as shown in FIG. 2, the first belt-like sheet LBa from the first holding roller 11a reaches the feeding mechanism 24 via the first feeding path 21a and the introduction path 23. The first belt-like sheet LBa can be fed to the subsequent printer by the feeding mechanism 24, and the second belt-like sheet LBb from the second holding roller 11b is fed to the feeding roller 211b and the pressing roller 212b of the second feeding path 21b. It is assumed that the start end portion is sandwiched between the second delivery path 21b.

  In FIG. 4, the control unit 100 determines whether or not there is a request for feeding the belt-like sheet LB from the printer (S1). When there is a feed request from the printer (YES in S1), the control unit 100 further confirms that there is no feed stop request for the belt-like sheet LB from the printer (NO in S2), and performs the first drive. The motor 31 is driven (S3). As a result, the first motor 31 rotates the feeding roller 241 of the feeding mechanism 24 and sequentially feeds the first belt-like sheet LBa toward the printer (see the state shown in FIG. 2). Thereafter, the control unit 100 determines whether or not the end portion of the first belt-like sheet LBa is detected based on the detection signal from the first paper edge detection sensor 40a (S4), and the detection signal from the second paper edge detection sensor 40b. The driving state of the first motor 31 is maintained while determining whether the end portion of the second belt-like sheet LBb is detected based on the above (S5) and whether there is a feed stop request from the printer (S2). (S3). As a result, the feeding of the first belt-like sheet LBa to the printer is continued.

  In the course of such processing, as shown in FIG. 5A, when the end portion of the first belt-like sheet LBa fed to the printer reaches the installation position of the first paper end detection sensor 40a, On the basis of the detection signal output from the first paper end detection sensor 40a, the control unit 100 recognizes that the terminal portion of the first belt-like sheet LBa has reached the installation position of the first paper end detection sensor 40a ( YES in S4). Then, the control unit 100 determines that the second belt-like sheet LBb from the second holding roller 11b before the terminal portion of the first belt-like sheet LBa that has already been fed enters the introduction path 23 from the first feeding path 21a. The second motor 32 is driven so that the starting end portion of the motor enters the introduction path 23 from the second delivery path 21b (S6). As shown in FIG. 5 (b), the start end of the second strip sheet LBb is the end portion of the first strip sheet LBa by the feed roller 211b of the second feed path 21b that is rotationally driven by the second motor 32. It is sent from the second sending path 21b to the introducing path 23 earlier. Then, the first belt-like sheet LBa is fed by the feeding roller 241 of the feeding mechanism 24 that is rotationally driven by the first motor 31, and the second belt-like sheet LBb is fed by the feeding rollers 231 and 232 that are rotationally driven by the second motor 32. However, the first belt-like sheet LBa is fed through the introduction path 23 in a state where it overlaps the upper side of the second belt-like sheet LBb.

  The control unit 100 recognizes the distance from the position where the end portion of the first belt-like sheet LBa is detected to the first set position Pc1 of the first heating means 50a, and the end portion of the first belt-like sheet LBa is the first set. When the position Pc1 is reached, the first motor 31 is stopped (S7: corresponding to the feed stop control means). Further, the control unit 100 recognizes the distance from the set position in the second delivery path 21b of the start end portion of the second strip sheet LBb to the first set position Pc1, and the start end of the second strip sheet LBb. When the section reaches the first set position Pc1, the second motor 32 is stopped (corresponds to the sheet introduction control means together with S8: S6). Thereby, as shown in FIG. 5C, the overlapping portion where the end portion of the first belt-like sheet LBa overlaps the upper side of the start end portion of the second belt-like sheet LBb is set at the first set position Pc1. Become.

  Actually, the end portion of the first belt-like sheet LBa and the end portion of the second belt-like sheet LBb have a certain length, and the substantially central portion of the overlapping portion formed by overlapping the certain length is the first. Control is performed so as to coincide with the set position Pc1.

  In this way, when the end portion of the first belt-like sheet LBa and the start end portion of the second belt-like sheet LBb are overlapped with the first belt-like sheet LBa facing upward, the overlapped portion is set at the first set position Pc1. The control unit 100 activates the first heating means 50a (S9). Then, under the control of the control unit 100, the first heating means 50a uses a hot air fan, a thermal head, or the like on the portion where the end portion of the first strip sheet LBa and the start end portion of the second strip sheet LBb are overlapped. Heating is performed to heat and bond the heat-activatable adhesive layer LBk provided at the end portion of the first belt-like sheet LBa and the start end portion of the second belt-like sheet LBb (heating control means).

  Returning to FIG. 4, when the overlapping portion between the end portion of the first strip sheet LBa and the start end portion of the second strip sheet LBb is connected by the operation of the first heating unit 50 a (see S <b> 9), the control unit 100 is thereafter processed. Determines whether there is a feed stop request from the printer (S2). If there is no feed stop request from the printer (NO in S2), the first motor 31 is driven again (S3). As a result, the feeding roller 241 of the feeding mechanism 24 rotates and the feeding of the first belt-like sheet LBa toward the printer is resumed. At that time, as shown in FIG. 3C, the overlapping portion between the terminal end portion of the first belt-like sheet LBa and the start end portion of the second belt-like sheet LBb is pressed by the feeding roller 241 and the pressing roller 242 to be connected. Further, the second belt-like sheet LBb is fed to the subsequent printer following the feeding of the first belt-like sheet LBa by the feeding roller 241.

  In this manner, while the second belt-like sheet LBb is being fed by the first motor 31 following the first belt-like sheet LBa, the new first belt-like sheet LBa is fed to the first holding roller 11a. And the starting end can be stopped on the first delivery path 21a. Then, the control unit 100 repeatedly executes the same processing (S2 to S5) as described above. In the process, when the terminal portion of the second sheet LBb fed to the printer reaches the installation position of the second paper end detection sensor 40b, the detection signal output from the second paper end detection sensor 40b at that time Then, the control unit 100 recognizes that the terminal portion of the second belt-like sheet LBb has reached the installation position of the second paper end detection sensor 40b (YES in S5). Then, the control unit 100 detects the first belt-like sheet LBa from the first holding roller 11a before the terminal portion of the second belt-like sheet LBb already fed enters the introduction passage 23 from the second sending-out route 21b. The second motor 32 is driven so that the starting end portion of the motor enters the introduction path 23 from the first delivery path 21a (S10). By the feed roller 211a of the first feed path 21a that is rotationally driven by the second motor 32, the starting end portion of the first belt-like sheet LBa comes from the first feed path 21a before the end portion of the second belt-like sheet LBb. It is sent out to the introduction path 23. The second belt-like sheet LBb is fed by the feeding roller 241 of the feeding mechanism 24 that is rotationally driven by the first motor 31, and the first belt-like sheet LBa is fed by the feeding rollers 231 and 232 that are rotationally driven by the second motor 32. However, the first belt-like sheet LBa is fed through the introduction path 23 in a state where it overlaps the upper side of the second belt-like sheet LBb.

  The control unit 100 recognizes the distance from the position where the end portion of the second belt-like sheet LBb is detected to the second set position Pc2 (see FIG. 2) of the second heating means 50b, and the end of the second belt-like sheet LBb. When the section reaches the second set position Pc2, the first motor 31 is stopped (S11: corresponding to the feed stop control means). Further, the control unit 100 recognizes the distance from the set position in the first delivery path 21a of the starting end portion of the first strip sheet LBa to the second set position Pc2, and the starting end of the first strip sheet LBa. When the section reaches the second set position Pc2, the second motor 32 is stopped (corresponding to the sheet introduction control means together with S12: S10). As a result, the overlapping portion where the start end portion of the first belt-like sheet LBb overlaps the terminal portion of the second belt-like sheet LBb is set at the second set position Pc2.

  In this way, the end portion of the second belt-like sheet LBb and the start end portion of the first belt-like sheet LBa are overlapped with the first belt-like sheet LBa facing upward, and the overlapping portion is set at the second set position Pc2. Then, the control unit 100 activates the second heating unit 50b (S13). Then, the second heating means 50b is substantially the same as the first heating means 50b described above. Under the control of the control unit 100, the second heating means 50b is configured such that the end portion of the second belt-like sheet LBb and the first belt-like sheet LBa. Is heated by a hot air fan or a thermal head, and the thermally activated adhesive layer LBk provided at the terminal end of the second belt-like sheet LBb and at the start edge of the first belt-like sheet LBa. Are heated to activate and connect the adhesive (heating control means).

  Returning to FIG. 4, when the overlapping portion between the end portion of the second strip sheet LBb and the start end portion of the first strip sheet LBa is connected by the operation of the second heating means 50b (see S13), the control unit 100 is thereafter connected. Determines whether there is a feed stop request from the printer (S2). If there is no feed stop request from the printer (NO in S2), the first motor 31 is driven again (S3). As a result, the feeding motor 241 of the feeding mechanism 24 rotates and the feeding of the second belt-like sheet LBb toward the printer is resumed. At that time, as shown in FIG. 3C, the overlapping portion of the terminal end portion of the second belt-like sheet LBb and the start end portion of the first belt-like sheet LBa is pressed by the feeding roller 241 and the pressing roller 242 to be connected. Further, the first belt-like sheet LBa is fed to the subsequent printer following the feeding of the second belt-like sheet LBb by the feeding roller 241.

  Thereafter, the same operation is continuously repeated by alternately setting the belt-like sheets LB on the first holding roller 11a and the second holding roller 11b.

  In the belt-like sheet feeding device according to the first embodiment as described above, the first belt-like sheet LBa from the first holding roller 11a is fed to the subsequent printer by the feeding mechanism 24 via the introduction path 23. When the end portion is detected based on the detection signal from the first sheet end detection sensor 40a, the end portion of the first strip sheet LBa and the start end portion of the second strip sheet LBb from the second holding roller 11b are detected. Is positioned at the first set position Pc1, and the first heating means 50a heats the overlapping portion of the first belt-like sheet LBa and the second belt-like sheet LBb, and is feeding the first belt-like belt The starting end portion of the second belt-like sheet LBb is connected to the terminal end portion of the sheet LBa and fed. Further, when the second belt-like sheet LBb is fed from the second holding roller 11b through the introduction path 23 to the subsequent printer by the feeding mechanism 24, the second belt-like sheet LBb is detected based on the detection signal from the second sheet end detection sensor 40b. When the end portion is detected, the end portion of the second belt-like sheet LBb and the start end portion of the first belt-like sheet LBa from the first holding roller 11a are overlapped and positioned at the second set position Pc2. The heating unit 50b heats the overlapping portion of the first belt-like sheet LBa and the second belt-like sheet LBb, and the end of the second belt-like sheet LBb being fed is connected to the starting end of the first belt-like sheet LBa. Sent. As described above, the start end portion of the other belt-like sheet LB is connected to the end portion of one belt-like sheet LB by a series of operations, so that the plurality of belt-like sheets LB are not interrupted without particularly troublesome work. It becomes possible to feed.

  Moreover, the overlapping part of 1st strip | belt-shaped sheet | seat LBa and 2nd strip | belt-shaped sheet | seat LBb is heated, the adhesive of the thermally active adhesive layer LBk provided in the start end part and termination | terminus part of a strip | belt-shaped sheet | seat is activated, and these strip | belt-shaped sheets Since LBa and LBb are connected, other connection members such as a connection seal are not required when connecting the strip sheets LBa and LBb. Therefore, for example, work for replenishing the connecting member to the attaching device for attaching the connecting member to the terminal end and the starting end of the two belt-like sheets LBa, LBb, work for managing the connecting member, etc. Without being performed, the plurality of belt-like sheets LB can be fed without being interrupted.

Next, a belt-like sheet feeding device according to a second embodiment of the present invention will be described.
The belt-like sheet feeding apparatus according to the second embodiment of the present invention is configured as shown in FIG. The belt-like sheet feeding apparatus according to the second embodiment has the above-mentioned first feature in that it has only a single heating means 50 and a paper end retracting mechanism (60, 61). It is different from the belt-like sheet feeding device according to the embodiment. In FIG. 6, the same members as those shown in FIG. 2 are denoted by the same reference numerals.

  In FIG. 6, this belt-like sheet feeding device is similar to the belt-like sheet feeding device according to the first embodiment described above, from the first holding roller 11a to the roller 12a, the first feeding path 21a, and the introduction path. The first belt-like sheet LBa that reaches the feeding mechanism 24 through 23 is fed to the subsequent printer by the rotational driving of the feeding roller 241 of the feeding mechanism 24. Further, the starting end portion of the second belt-like sheet LBb from the second holding roller 11b through the roller 12b to the second delivery path 21b is stopped in the second delivery path 21b. Although not shown in FIG. 6, as in the first embodiment described above, the second belt-like sheet LBb from the second holding roller 11b is sent to the second delivery similarly to the first belt-like sheet LBa. The feed path 24b leads to the feed mechanism 24 via the introduction path 23. The feed mechanism 24 enables feeding to the subsequent printer, and the first feed roller 11a sends the first feed via the roller 12a. The starting end portion of the first belt-like sheet LBa reaching the path 21a is stopped in the first sending path 21a.

  A heating means 50 is installed at a position adjacent to the feeding mechanism 24 in the introduction path 23. The heating unit 50 has the same structure as the first heating unit 50a and the second heating unit 50b (see FIG. 2) in the first embodiment described above.

  In the introduction path 23, a feed roller 231 and a pressing roller 233 facing the feed roller 231 are provided at a position adjacent to the connection portion between the first feed path 21 a and the second feed path 21 b, and a position adjacent to the heating unit 50. The feed roller 232 and the presser roller 234 facing the feed roller 232 are provided. The feed roller 241 in the feed mechanism 24 and the feed roller 232 provided in the introduction path 23 are coupled to the first motor 31. The feed rollers 211 a and 211 b in the first feed path 21 a and the second feed path 21 b and the feed roller 231 in the introduction path 23 are coupled to the second motor 32.

  A paper end retracting mechanism is provided at a predetermined position between the feed roller 231 and the feed roller 232 in the introduction path 23. This sheet end retracting mechanism switches between a claw body 61 and an initial position where the claw body 61 does not protrude into the introduction path 23 and a protruding position where the claw body 61 inclines obliquely downward and protrudes into the introduction path 23. The switching mechanism 60 is configured to be provided.

A control system in the belt-like sheet feeding apparatus having the above-described structure is configured as shown in FIG.
As in the case of the belt-like sheet feeding device according to the first embodiment, upstream of the first sheet end detection sensor 40a and the second feeding path 21b provided at the upstream end of the first feeding path 21a. A second sheet edge detection sensor 40 b provided at the side edge is connected to the control unit 100. The control unit 100 includes a first motor 31 serving as a drive source for the feeding roller 241 of the feeding mechanism 24 and the feeding roller 232 in the introduction path 23 in response to detection signals from the respective sheet edge detection sensors 40a and 40b. Drive control of the second motor 32 serving as a drive source for the feed roller 211a in the first feed path 21a, the feed roller 211b in the second feed path 21b, and the feed roller 231 in the introduction path 23 is performed. The control unit 100 also performs drive control of the heating mechanism 50 and the switching mechanism 60 in the paper end retracting mechanism based on detection signals from the paper edge detection sensors 40a and 40b.

The control unit 100 executes processing according to the procedure shown in FIGS.
In FIG. 8, the control unit 100 determines whether or not there is a feeding request for the belt-like sheet LB from the printer (S21). When there is a feed request from the printer (YES in S1), the control unit 100 further confirms that there is no feed stop request for the belt-like sheet LB from the printer (NO in S22), and performs the first drive. The motor 31 is driven (S23). As a result, the first motor 31 rotates the feeding roller 241 of the feeding mechanism 24 and sequentially feeds the first belt-like sheet LBa toward the printer (see the state shown in FIG. 6). Thereafter, the control unit 100 determines whether or not the end portion of the first belt-like sheet LBa is detected based on the detection signal from the first paper edge detection sensor 40a (S24), and the detection signal from the second paper edge detection sensor 40b. The driving state of the first motor 31 is maintained while determining whether the end portion of the second belt-like sheet LBb is detected based on the above (S25) and whether there is a feed stop request from the printer (S22). (S23). As a result, the feeding of the first belt-like sheet LBa to the printer is continued.

  In the course of such processing, if the control unit 100 determines that the end portion of the first belt-like sheet LBa has been detected based on the signal from the first paper end detection sensor 40a (YES in S24), the control unit 100 is fed. It is determined whether or not the end portion of the first belt-like sheet LBa has reached a predetermined reverse feed position (S26). This reverse feed position is set slightly upstream of the pawl 61 of the paper end retracting mechanism. For example, the control unit 100 uses the first paper end detection sensor 40a to set the end of the first belt-like sheet LBa. Based on the rotation speed (rotation angle) of the first motor 31 from the detected timing, it is determined whether or not the first belt-like sheet LBa has reached the reverse feed position.

  The control unit 100 determines that the terminal portion of the first belt-like sheet LBa being fed has reached the reverse feed position as shown in FIG. 10 (a) and enlarged in FIG. 11 (a). When this is done (YES in S26), the process proceeds to the process shown in FIG. 9, and the drive control of the switching mechanism 60 is performed so that the claw body 61 is switched to the projecting position projecting into the introduction path 23 as shown in FIG. (S27: equivalent to first switching control means) Then, the control unit 100 causes the first motor 31 to reversely rotate and then stop so that the first belt-like sheet LBa is reversely fed by a predetermined distance (S28: equivalent to sheet reverse feed control means). By the reverse rotation of the first motor 31, the feeding roller 241 of the feeding mechanism 24 and the feeding roller 232 of the introduction path 23 are reversed, and the first belt-like sheet LBa is fed backward. And the terminal part of 1st strip | belt-shaped sheet | seat LBa reversely fed rides on the nail | claw body 61 in a protrusion position, as shown in FIG.10 (b) and expanded in FIG.11 (c).

  When the reverse rotation drive control (S28) for the first motor 31 is completed, the control unit 100 switches the switching mechanism so that the claw body 61 returns to the initial position retracted from the introduction path 23 as shown in FIG. 60 is controlled (S29: equivalent to second switching control means). By switching the nail body 61 back to the initial position, the end portion of the first belt-like sheet LBa is held by the nail body 61 and the guide plate 251a provided in the vicinity of the pressing roller 234, and the first belt that has run on the nail body 61 is retained. The end portion of the belt-like sheet LBa is retracted from the introduction path 23 (see FIG. 12A).

  Thereafter, the control unit 100 drives the second motor (S30). The second belt-like sheet LBb from the second holding roller 11a is fed from the second feed path 21b by the feed roller 211a of the second feed path 21b and the feed roller 231 of the introduction path 23 that are rotationally driven by the second motor 32. Further, it is sent through the introduction path 23. Then, as shown in FIG. 12B, the start end portion of the second strip sheet LBb enters the lower side of the first strip sheet LBa whose end portion is retracted from the introduction path 23. Then, for example, the control unit 100 drives the first motor 31 at the timing when the start end portion of the second belt-like sheet LBb reaches the feed roller 232 of the introduction path 23 (S31). Accordingly, as shown in FIG. 12C, the first belt-like sheet LBa is driven to rotate by the first motor 31 in a state where the end portion of the first belt-like sheet LBa and the start end portion of the second belt-like sheet LBb overlap each other. Are fed by the feed roller 232 and the feed roller 241 and the second belt-like sheet LBb is rotated by the second motor 32. The feed roller 211b of the second feed path 21b, the feed roller 231 of the introduction path 23, and The feed roller 232 is driven to rotate by the first motor 31.

  The control unit 100 stops the second motor 32 at the timing when the start end of the second belt-like sheet LBb (new belt-like sheet LB to be replenished) is expected to reach the set position Pc of the heating means 50 (S32: S30). And equivalent to the sheet introduction control means). Further, the control unit 100 stops the first motor 31 at a timing when it is expected that the terminal portion of the first belt-like sheet LBa (the feeding belt-like sheet LB) has reached the set position Pc (S33: overlapping with S31). Equivalent to feed control means). As a result, the overlapping portion between the end portion of the first strip sheet LBa and the start end portion of the second strip sheet LBb is positioned at the set position Pc as shown in FIG. The feeding of the LBa and the second strip sheet LBb is stopped.

  In this state, the control unit 100 drives the heating unit 50 in a state where the overlapping portion of the first belt-like sheet LBa and the second belt-like sheet LBb is set at the set position Pc (S34). As a result, the heating means 50 is controlled by the control unit 100 in the same way as in the first embodiment described above, and the heating means 50 is connected to the end of the first belt-like sheet LBa and the second belt-like sheet LBb. The portion where the start end portion is overlapped is heated by a warm air fan or a thermal head, and the thermally active adhesive layer LBk provided at the end portion of the first strip sheet LBa and the start end portion of the second strip sheet LBb Heat to activate and connect the adhesive (heating control means). Thereafter, the control unit 100 returns to the processing shown in FIG. 8 and determines whether or not there is a feed stop request from the printer (S22). If there is no feed stop request from the printer (NO in S22), The first motor 31 is driven again (S23).

  As a result, the feeding roller 241 of the feeding mechanism 24 rotates and the feeding of the first belt-like sheet LBa toward the printer is resumed. At that time, as in the case of the first embodiment described above, the second belt-like sheet LBb is fed to the subsequent printer following the feeding of the first belt-like sheet LBa by the feeding roller 241.

  In this manner, while the second belt-like sheet LBb is being fed by the first motor 31 following the first belt-like sheet LBa, the new first belt-like sheet LBa is fed to the first holding roller 11a. And the starting end can be stopped on the first delivery path 21a. Then, the control unit 100 repeatedly executes the same processing (S22 to S25) as described above. In the process, when the end portion of the second sheet LBb fed to the printer is detected by the second sheet end detection sensor 40b (YES in S25), the same processing as described above (S26 to S34). (S22 to S25) are performed. As a result, the overlapping portion between the end portion of the second belt-like sheet LBb and the start end portion of the first belt-like sheet LBa is connected, and when the feeding of the second belt-like sheet LBb is resumed, it is connected to the second belt-like sheet LBb. The first belt-like sheet LBa is continuously fed.

  Thereafter, the same operation is continuously repeated by alternately setting the belt-like sheets LB on the first holding roller 11a and the second holding roller 11b.

  In the belt-like sheet feeding device according to the second embodiment as described above, the plurality of belt-like sheets LB are not interrupted without particularly troublesome work as in the case of the first embodiment described above. In this case, it is not necessary to use a connection member for connecting the two belt-like sheets LB. Further, unlike the case of the first embodiment, it is not necessary to prepare two heating means, and only a sheet end retracting mechanism (switching mechanism 60 and claw body 61) having a relatively simple structure is added. Well, the structure of the device can be relatively simple.

In the above-described embodiment, the belt-like sheet LB is fed as a belt-like sheet. However, the belt-like sheet is not limited to this, and is a sheet-like one that should be fed continuously to a subsequent apparatus or the like. If it is, it will not specifically limit. In addition, the two sheet edge detection sensors 40a and 40b are provided corresponding to the belt-like sheets LBa and LBb, but they are introduced upstream of the common path, for example, the claw body 61 in the introduction path 23. A single sheet edge detection sensor 40 that detects the end portion of the belt-like sheet (which may be either the first belt-like sheet LBb or the second belt-like sheet LBb) moving in the path 23 can be used. In this case, the control system 100 recognizes by any method using, for example, a flag or a counter whether the belt-like sheet LB to be fed is from the first holding roller 11a or the second holding roller 11b. Can be easily implemented.
