Fig. 1 is a perspective view of the roll printer according to the present invention in the rear view direction. Fig. 2 is a sectional view taken at C-C in fig. 1, and in fig. 2, the sectional view is omitted for convenience of illustration. Fig. 3 is a right-side view schematically showing a main part of the internal structure of the roll paper printer of fig. 2. Fig. 4 is a schematic diagram of essential parts in fig. 2, and in fig. 4, the first holding portion 115, the second holding portion 131, the guide roller unit 136, and the detection portion 141 are mainly shown.

Referring to fig. 1 to 4, a printer for a web according to the present embodiment includes: a first holding portion 115, a second holding portion 131, a conveying portion 103, and a printing portion 101. The first holding portion 115 rotatably supports the base material 201 stored in a roll shape. The second holding portion 131 is disposed above the first holding portion 115. The second holding portion 131 has a first driving portion 132 and a rotating shaft 133. The first driving unit 132 is connected to the rotating shaft 133, and drives the rotating shaft 133 to rotate so that the protective film 203 peeled from the surface of the base material 201 is wound around the rotating shaft 133. The conveyance unit 103 is disposed in front of the first holding unit 115, and continuously pulls the base material 201 from which the protective film 203 is peeled. The printing portion 101 is disposed between the first holding portion 115 and the conveying portion 103 in the front-rear direction. The printing unit 101 has a printing table 104, and the base material 201 pulled by the conveying unit 103 is held on the printing table 104.

The web printer according to the present embodiment can be applied to a roll-shaped substrate 201, and can automatically peel off the protective film 203 on the surface of the substrate 201 at least to some extent. Specifically, the surface of the base material 201 is covered with the protective film 203 and is held in the first holding portion 115 in a roll form. When the base material 201 is attached, the worker first peels off the protective film 203 at the leading end of the base material 201, then winds the peeled protective film 203 around the rotation shaft 133, and pulls the base material 201 from which the protective film 203 is peeled to the conveyance unit 103 via the print table 104. Thus, when the print head 112 of the printing unit 101 prints on the base material 201 held on the print table 104, the carrying unit 103 pulls the base material 201 and continues to feed the base material, and at the same time, since one end of the protective film 203 is wound around the rotary shaft 133, the first driving unit 132 of the second holding unit 131 can automatically wind the protective film 203, which is peeled off from the surface of the base material 201 as the base material 201 is fed, around the rotary shaft 133 by driving the rotary shaft 133 to rotate. Therefore, the workload of the operator can be reduced, and the working efficiency can be improved.

With continued reference to fig. 2 and 3, the printer for a web material of the present embodiment may include, for example, a base 109, and the base 109 may be formed by, for example, machining a sheet metal member into, for example, a box shape. A print area 110 is provided in the middle of the base 109 in the left-right direction, and the print table 104 of the print section 101 is provided in the print area 110. The printing area 110 is open in the front-rear direction, thereby facilitating feeding of the base material 201 and the like. The printer 101 further includes a robot 111 driven in the left-right direction, and a print head (for example, a crystal marker or other pattern) 112 for printing on the base material 201 is mounted on the robot 111. While the substrate 201 is continuously fed, the robot 111 can drive the print head 112 to move in the left-right direction, thereby printing a desired crystal mark, a desired pattern, or the like on the substrate 201 placed on the print table 104.

The conveyance unit 103 is provided, for example, directly in front of the print deck 104. The conveyance section 103 includes, for example, a first clamp roller 106 and a second clamp roller 107. The first and second nip rollers 106 and 107 are opposed to each other in the vertical direction and nip the substrate 201. The first clamping roller 106 is arranged above the second clamping roller 107. Both ends in the axial direction of the first clamping roller 106 are rotatably mounted on the left and right sides of the printing area 110 of the base 109. The first clamping roller 106 is driven by a known drive device 108, such as a motor. Thus, when the first grip roller 106 is driven by the driving device 108, the first grip roller 106 and the second grip roller 107 can be continuously fed forward while pulling the base material 201.

With continuing reference to fig. 2 to 4 and with additional reference to fig. 1, the first holding portion 115 is disposed, for example, below and behind the printing platform 104. In order to easily mount the base material 201, the first holding portion 115 may include, for example, a first bracket 117 and a support shaft 116. The first brackets 117 include, for example, a pair, and are respectively attached to the rear surface of the base 109 in the left-right direction so as to face each other, and protrude outside the base 109. The support shaft 116 is detachably supported on the first support 117, and rotatably supports the substrate 201. For example, the support shaft 116 may be inserted into the roll of substrate 201 at the time of installation, and then the support shaft 116 may be placed on the first bracket 117.

The second holding portion 131 is provided, for example, at the upper rear of the printing platform 104. In order to easily collect the protective film 203 and to detach the collected protective film 203, the second holding portion 131 may also include, for example, the second holder 134. The second brackets 134 also include, for example, a pair, and are attached to the rear surface of the base 109 so as to face each other in the left-right direction, and extend out of the base 109. Further, the second bracket 134 is disposed above the first bracket 117. The rotary shaft 133 is mounted on the second bracket 134 via a bearing, for example. In addition, the first driving part 132 may include, for example, a stepping motor 135, and the stepping motor 135 is connected to the rotation shaft 133, thereby driving the rotation shaft 133 to rotate. In the present embodiment, the cost of the roll printer can be reduced by selecting a stepping motor as an actuator to rotate the rotary shaft 133 and thereby collecting the protective film 203.

Referring primarily to fig. 4, with continued reference to fig. 2 and 3, to accurately and reliably wind the peeled protective film 203, in some embodiments, the web printer may further include a guide roller unit 136. The guide roller unit 136 is provided to guide the protective film 203 peeled from the surface of the base material 201 to the rotation shaft 133.

For example, the guide roller unit 136 may include a first guide roller 137 and a second guide roller 138 that are opposite to each other in the up-down direction. A first guide roller 137 and a second guide roller 138 are provided between the first holding portion 115 and the printing portion 101 in the front-rear direction. The base material 201 having the protective film 203 adhered to the surface thereof passes through between the first guide roller 137 and the second guide roller 138, and the protective film 203 is peeled off from the surface of the base material 201 in front of the first guide roller 137 and the second guide roller 138. The first guide roller 137 and the second guide roller 138 are, for example, bridged on the base 109. The second guide roller 138 is disposed directly above the first guide roller 137, and the first guide roller 137 and the second guide roller 138 vertically sandwich the base material 201 having the protective film 203 adhered to the surface thereof. When mounting the substrate 201, the worker first passes the substrate 201 with the protective film 203 attached thereon through the first guide roller 137 and the second guide roller 138, and supports the substrate 201 by the first guide roller 137. The protective film 203 is then peeled off in front of the first guide roller 137 and the second guide roller 138, and the protective film 203 is pulled back along the circumferential direction of the second guide roller 138 and then onto the rotating shaft 133. By providing the first guide roller 137 and the second guide roller 138, the peeled protective film 203 can be guided to the rotation shaft 133 more reliably and accurately.

In addition, in order to buffer more protective film 203, the guide roller unit 136 may further include a third guide roller 139, and the third guide roller 139 is disposed above and behind the first guide roller 137 and the second guide roller 138 to guide the peeled protective film 203. Specifically, the third guide roller 139 is located rearward of the second guide roller 138 in the front-rear direction and above the second guide roller 138 in the up-down direction. The third guide roller 139 is also located forward of the rotation shaft 133 in the front-rear direction and below the rotation shaft 133 in the up-down direction. After the protective film 203 is peeled off in front of the second guide roller 138, the protective film 203 is pulled to the rotation shaft 133 along the second guide roller 138 and the third guide roller 139, and the protective film 203 is lifted relative to the base material 201 in the process of being guided, so that more protective film 203 can be buffered.

In addition, in order to avoid the protective film 203 from largely shaking or the like, the guide roller unit 136 may further include a fourth guide roller 140, and the fourth guide roller 140 is disposed in front of and below the rotation shaft 133 and guides the protective film 203 guided by the third guide roller 139 to the rotation shaft 133.

With continuing reference to fig. 4 and with additional reference to fig. 2, in some embodiments, to detect the amount of peeling (buffer amount) of the protective film 203 that is peeled off, in some embodiments, the web printer may further include a detection portion 141, the detection portion 141 being configured to detect the amount of peeling of the protective film 203 that is peeled off from the surface of the base 201 to be stored to the rotation shaft 133. For example, the detection section 141 may be provided between the third guide roller 139 and the fourth guide roller 140, and detect the peeling amount of the protective film 203 between the third guide roller 139 and the fourth guide roller 140. The detection part 141 may include a detector 142 such as a photo sensor, a proximity switch, etc., and the stepping motor 135 of the first driving part 132 drives the rotation shaft 133 to rotate in a case where the detector 142 detects the protective film 203. For example, in a case where the detector 142 of the detection section 141 detects that the amount of peeling of the buffered protective films 203 reaches a preset amount, the stepping motor 135 of the first driving section 132 is rotated by a preset number of revolutions, thereby causing these buffered protective films 203 to be wound around the rotating shaft 133. By using the detection section 141 in cooperation with the stepping motor 135 to collect the protective film 203 in this manner, a dedicated, expensive torque motor is replaced, and the cost of the printer for a roll material can be greatly reduced. In particular, the roll sheet printer according to the present embodiment can be directed to an individual user, and in this case, the cost of the roll sheet printer can be reduced, thereby eventually reducing the selling price for the individual user. Needless to say, the first driving unit 132 may select a servo motor or a torque motor as an actuator, regardless of the cost.

In order to guide the protective film 203 more accurately and improve the detection of the peeling amount of the protective film 203 by the detector 142 of the detection section 141, the detection section 141 may further include: and a pressing member 143, the pressing member 143 abutting the protective film 203 to be stored in the rotating shaft 133, which is peeled from the surface of the base material 201, from above, and biasing the protective film 203 downward. The pressing member 143 presses the protective film 203 downward as the amount of peeling of the protective film 203 increases. The detector 142 is provided to detect the protective film 203 pressed downward by the pressing piece 143. For example, the pressing member 143 is provided between the third guide roller 139 and the fourth guide roller 140 in the front-rear direction, and the protective film 203 peeled off from the surface of the base material 201 passes around the third guide roller 139, abuts against the pressing member 143 from below the pressing member 143, passes around the pressing member 143, and extends toward the fourth guide roller 140. Since the pressing member 143 always presses the protective film 203 downward, the pressing member 143 continuously presses the protective film 203 downward as the peeling amount of the protective film 203 increases. This ensures that the protective film 203 does not shake, and the protective film 203 can be guided more accurately. When the protective film 203 is pressed against the detection region of the detector 142, the protective film 203 is detected by the detector 142, and the stepping motor 135 of the first driving unit 132 operates to start collecting the protective film 203.

In some embodiments, the pressing member 143 may be, for example, a pressing roller movable in the up-down direction, which is supported on the protective film 203 to be stored to the rotating shaft 133, peeled off from the surface of the base material 201. For example, guide frames 144 that guide in the vertical direction are attached to both sides of the printing area 110 of the base 109 in the horizontal direction. Both ends of the press roller in the axial direction are guided by the guide frame 144 to be freely slidable in the up-down direction, respectively. The pressing roller is supported on the protective film 203, gradually presses the protective film 203 downward as the peeling amount of the protective film 203 increases, and causes the protective film 203 to be detected by the detector 142. In the case where the stepping motor 135 drives the rotation shaft 133 to rotate to collect the protective film 203, the protective film 203 lifts the pressing roller upward.

Although the example in which the pressing member 143 is a pressing roller has been described above, the pressing member 143 is not limited to this example, and an elastic member such as a spring may be used.

Thus, the printer according to each of the above embodiments can automatically peel off the protective film 203 on the surface of the base material 201 at least to some extent. Therefore, the workload of the operator can be reduced, and the working efficiency can be improved.

Further, by using a combination of the detector 142 and the stepping motor 135, the cost of the printer can be reduced.

Further, by using the pressing member 143, the detection of the peeling amount of the protective film 203 by the detector 142 of the detection portion 141 can be improved.

The specific features described in the above embodiments may be combined in any way without contradiction, and various combinations are not separately described in this embodiment for unnecessary repetition.

The above examples are merely illustrative of the technical solutions of the present embodiments and are not intended to be limiting, and any modifications or equivalent substitutions that do not depart from the scope of the present embodiments should be included in the technical solutions of the present embodiments.
