[Problem to be Solved by the Invention] For this reason, conventionally, the supply of roll paper has been stopped for a considerable period of time at the time of connection, resulting in a reduction in the operating efficiency of corrugators, container manufacturing equipment, etc. Ta. This not only causes a loss of operating time, but also causes variations in the quality of cardboard, containers, and the like.

[Means for Solving the Problems] Therefore, in view of the above points, the present inventor has developed the present invention device as a result of intensive research. In an apparatus for continuously supplying sheets by joining a leading end portion of a rolled sheet with another rolled sheet, a support body rotatably supports a plurality of rolled sheets arranged in a fixed direction, and the support body a gripping tool that supports the leading end of the rolled sheet supported at least when the rolled sheet is moved to a position facing the transport path, and a leading end of each sheet supported by the supporting body by moving the supporting body a drive device for positioning the sheet in the supply section of the transfer path; a detector for detecting the end of one rolled sheet; and a detector for detecting the end of the one rolled sheet and the leading end of the other rolled sheet; A coupling device which is connected by a coupling part provided in the transfer passage, and an output part which is provided in the discharge part of the transfer passage and which transfers the end of one rolled sheet to the coupling part. A splicing device is provided in the supply section of the passage and includes an inlet drive section that transports the leading end of another rolled sheet to the joining section, and the IF is controlled to operate and stop by the detector. , by a feeding device provided on the connecting lid device to continuously feed the rolled sheet, or by combining the end portion of one rolled sheet with the leading end portion of another rolled sheet. A device for continuously supplying sheets includes a support that rotatably supports a plurality of rolled sheets arranged in a fixed direction, and a rolled sheet supported by the support that faces at least a transport path. a gripper that supports the leading end of the rolled sheet when moving to a position where the rolled sheet is to be moved; a drive device located in the supply section of the passage; and a slide for positioning the leading end of each sheet in the supply section of the transfer passage by sliding the rolled sheet supported by the support along the spindle. a device, a detector for detecting a distal end of one rolled sheet 1, and a coupling for connecting the distal end of the one rolled sheet and the leading end of another rolled sheet at a joint provided in the transfer path. an apparatus, an output side drive section provided in the discharge section of the transfer passage for transferring the end of one rolled sheet to the joining part, and a leading end of the other rolled sheet provided in the supply section of the transfer passage; a paper splicing device consisting of an inlet drive unit that transports the paper to the joining part, and a feeder that is operated and stopped by the detector and is provided in front of the paper splicing device and continuously feeds out the rolled sheet. The reason lies in the fact that it is configured from a device.

Here, the term "rolled sheet" as used herein refers to a tape-shaped paper rolled into a roll. It is something. This rolled sheet is obtained by winding the sheet around a drum or the like, and is rotatably supported by a shaft provided on a support body and fed out from the tip to be supplied to a container manufacturing machine or the like. The rolled sheet is fed out by an ejecting device such as a separately provided drive roller.

"Support" refers to something that rotatably supports a plurality of rolled sheets arranged in a certain direction. By sliding along the axis, it is moved to a position facing the transport path, that is, a position for feeding the sheet into the transport path. At this time, the roll is supported by the gripper so that the leading end of the sheet is located at the supply section of the transport path.

The movement of the support body is vertical, horizontal, braking, rotation, etc. For example, in the case of rotation, the rolled sheet is supported on a turntable. In the case of left and right, the table supporting the rolled sheet is reciprocated on the rail to sequentially position new rolled sheets in the supply section.

Therefore, arranging the rolled sheets in a certain direction means arranging them radially in the case of rotation, and arranging the rolled sheets adjacently in an upright state in the case of left and right. Moreover, in the case of top and bottom, the rolled sheets are vertically stacked and arranged either in an upright state or in a horizontal state. Of course, the order in which the rolled sheets are placed in the supply section may be any method as long as they can be reciprocated or rotated in whole or in part.

In order to move the rolled sheet with the support body fixed, the rolled sheet provided on the support body is moved along a support shaft that rotatably supports the rolled sheet. in this case,
By pushing or pulling the rolled sheet laterally or vertically with a slide device, it is positioned in the supply section of the transfer path. Here, the slide device ε refers to a device that moves the rolled sheet supported on a support shaft so that its tip is located in the supply section of the transfer passage. The width adjustment plate is moved by moving the width adjustment plate that presses the width, or the width adjustment plate is moved by rotating a rod with threads using a motor and screwing the width adjustment plate onto this.

Rolled sheets do not need to be directly supported on a support;
The rolled sheet may be supported on a separate truck or the like, and the truck may be placed on the support.

The "grip" is a device that supports the leading end of the rolled sheet to position the leading end in the supply section of the transfer path. The gripping tool is provided at a position facing the supply section of the transfer passage. In other words, it is sufficient that it is between the rolled sheet sent to a position facing the supply section of the transfer path and the supply section of the transfer path. Therefore, the gripper may be provided independently, or may be provided on a support or a trolley. For example, when moving the support to make each rolled sheet face the transport path, the support may be provided on the support or a truck for each rolled sheet. In this case, when setting the rolled sheet on a support or a trolley, the leading end of the rolled sheet is gripped by a gripping tool, and in this state, the roll is placed with the leading end of the sheet into the supply section of the transport path. position so that it engages with the inlet (III drive section) provided in the supply section.

If only one gripping tool is provided, the gripping tool is activated when the rolled sheet is sent to a position opposite to the transport path, and supported so that the leading end of the rolled sheet is positioned at the supply section of the transport path. . Therefore, in order to support the leading end of the rolled sheet with the gripping tool, the leading end is fixed or supported by the gripping tool so that the leading end slightly protrudes from the gripping tool. When the rolled sheet is transferred by the entry side drive unit, the gripping tool is used to release the gripping, or to hold it loosely so as not to affect the transport.

"Drive device" refers to a device that moves the support.

This may be a motor, a hydraulic cylinder, a pneumatic cylinder, a chain conveyor, a belt conveyor, etc.

The "transfer path" is a traveling path for sending out the rolled sheet. One end of this has a supply section for receiving the tip of the rolled sheet, and a drive section (111) provided in the supply section pulls out the sheet and transports the tip to the joining section. Further, at the other end of the transfer passage, there is provided an output (11) drive unit that transfers the end portion of one rolled sheet to the joining part when all the rolled sheets are fed out. The drive unit and the output side drive unit need only be driven when the rolled sheets are combined, and are left free when the sheets are continuously transported by the delivery device.The input side drive unit is a roller that moves in the vertical direction, for example, and pinches the tip of the rolled sheet supported by the gripper and sends it out.The output side drive section may also have the same structure as the input side drive section.This transfer The passage is provided with various detectors for detecting the presence or absence of sheets around the passage, and a coupling device that connects the end and the tip of the rolled sheet.The transfer passage is also branched into multiple sections on the supply side. However, each supply section may be provided with an inlet drive section, and the rolled sheets may be merged, connected, and transported from these drive sections.

"Paper splicing device" is a general term for the above-mentioned transfer path and equipment such as a joining device provided around it. In other words,
This device is activated when all rolled sheets supported by a support are sent out and combined with the next rolled sheet.

Therefore, this paper splicing device is provided with a detector that detects the presence or absence of a rolled sheet. The detector is generally a so-called photoelectric switch that detects when the end of the rolled sheet has passed, but it may also be a mint switch or the like. Further, the location to be detected is usually the transfer path, but it may also be the area around the gripping tool. A signal from this detector causes the feeding device that is continuously feeding out the rolled sheet to be stopped. The end of the sheet that has stopped running is transported to the joining section by the exit drive section.

On the other hand, the leading end of the next newly rolled sheet is sent to the supply section of the transfer path by moving the support with a drive device or by moving it with a slide device. Then, the leading end is transferred to the joining section by the entry side drive section (if the supply section and entry side drive section are branched into multiple parts, one of the new rolled sheets located in the supply section is transferred to the joining section). (transferred to the department). The positioning of the distal end and the leading end of the sheet at the joining section is usually achieved by providing a photoelectric switch to control the exit drive section and the input drive section. In addition, the output side drive section and the input side drive section may be operated for a preset time, controlled by a timer, or a photoelectric switch and a timer may be combined. After the end and tip of the sheet are joined at the joint, the two are connected using a joining device. The distal end and tip may be somewhat shaped or gapped. A coupling device generally connects the two by pasting tape, but
The two may be overlapped and attached using an adhesive. When the connection is completed in this way, the output side drive section and the input side drive section are made free, and the delivery device is driven again to continuously send out the sheets.

Incidentally, since the end portion of the rolled sheet has a tendency to bend, this portion may be cut to some extent at the stage of transporting the end portion to the joint portion.

Therefore, in this case, a cutter, a positioning device, a device for removing cut pieces, etc. may be provided. Further, a device or the like may be provided for pressing from the opposite side when joining by the joining device.

The "feeding device" is a device that continuously feeds out rolled sheets. This is a roller rotationally driven by, for example, a motor, and uses this row arm to draw out the rolled sheet rotatably supported on the support. The sending device is
Any device may be used as long as it is provided in front of the paper splicing device, that is, on the opposite side of the support, and continuously pulls out rolled sheets. Therefore, this delivery device does not necessarily need to be provided in the apparatus of the present invention, and a delivery device provided in the container manufacturing machine may be used.

[Embodiments] Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

FIG. 1(a) (B and B respectively show an embodiment of the continuous feeding device 1 according to the present invention, and a turntable 2 and paper splicing device 3 supporting a plurality of roll winding sheets) (C) are the main components. This is what I did. The turntable 2 rotatably supports 28 rolled sheets (C), and is provided with a gripper 21 for supporting and fixing the tip of the solid rolled sheets (C). Then, a motor A22 is provided which rotates the turntable 2 in order to position the solid raw J rolled sheet (C) in the supply section of the transfer passage 31. The limit switch 23 provided at the bottom of the motor A
This is done by controlling 22. Then, the cylinder A24 is operated to fix the turntable 2.

The gripping tool 21 is configured such that when the leading end of the rolled sheet (C) is located at the supply section of the transfer path 31 and is driven by the entrance roller 35, the sheet is gripped by the cylinder B25 provided at the lower part of the gripping tool 21. I am trying to get it removed. That is, by operating the cylinder 825, the pressing plate 20 pressed by the spring is pushed up and the rolled sheet (C) is pushed up.
The tip is made to be open.

The roll winding sheet (C) is normally driven continuously on the transfer path 31 by a delivery device (as shown).

When this rolled sheet (C) is used up, the next new rolled sheet (C) is positioned at the supply section of the transfer road 31 by the operation described above, and the previous rolled sheet (C) is
) and then continuously fed out again by the feeding device. Therefore, the delivery device is stopped while the paper splicing process is in operation.

The paper splicing device 3 is equipped with a detector 32 in the supply section of the transfer path 31 to detect when the running rolled sheet (C) is gone (in this figure, only the floodlight is shown among the phototube switches). >, the paper splicing process is started by this signal. When the end of the rolled sheet (C) passes below this detector 32, the detector 32 detects this and stops the feeding device. Then , out (11) Raise the out side roller 33 which is the drive unit and move out out 01lJ drive roller 50

be transported to. Next, the roll sheet (C) positioned in the supply section of the transfer passage 31 is raised by raising the entrance roller 35, which is the entrance drive section, and driving the entrance drive roller 51. ) is transferred to the joining part 34. In this way, the rolled sheet (C)
With the ends and tips joined, a tape 37 is attached by a connecting device 36 to connect the two. The outgoing drive roller 50 and the incoming driving roller 51 are driven by a motor B52 and a motor C53, respectively, and transfer the rolled sheet (C) by pressing the outgoing roller 33 and the incoming roller 35 from below.

The positioning of the end and the leading end of the rolled sheet (C) at the joint 34 is performed by an end detector 38 and a leading end detector 39, which are optical switches, and these are used to control the motor B5, respectively.
2 and motor C53. After connecting the rolled sheets (C), the output roller 33 and the input roller 35 are lowered, the feeding device is operated again, and the rolled sheets (C) are connected.
Start sending out C).

Figure 2+8) (bl shows another example of the support,
Four carts 26 supporting seven rolled sheets (c) are placed on the turntable 19.

The cart 26 is provided with a support shaft that rotatably supports the rolled sheet (C) and a gripper 21 that supports the tip of the rolled sheet (C). After all the rolled sheets (C) supported on one cart 26 are sent out, the cart 26 is lowered from the turntable 20, and the cart 26 with the newly set rolled sheet (C) is transferred to the turntable 20.
I'll put it on. For this reason, an example of a turntable IS is provided with a ramp 27 for getting on and off. The rolled sheet (C) supported by the truck 26 is supplied to the transfer passage 31 in the same manner as in the embodiment described above.

FIG. 3 (al (b)) shows another example of the support, in which seven rolled sheets (C) are placed on a lifting table 18. This lifting table 18 has a screw shaft 17 is rotated by a motor D1B to move up and down.The rolled sheet (C) placed on the lifting platform 18 is
They are pushed up into the supply section of the transfer passage 31 in order from the top and sent to the transfer passage 31 by the entrance drive roller 51. In this example, two lifting tables 18 are provided so as to be movable in the lateral direction, and when the rolled sheet (C) on one lifting table 18 runs out,
The other lifting platform 18 is moved to supply a new rolled sheet (C).

In this embodiment, the rolled sheet (C
) are guided by the transport path 31 so that the sheets (C) are horizontal, but the rolled sheets (C) may be combined and sent out vertically.

FIGS. 4(a) and 4(b) show still another embodiment of the support, in which a rolled sheet (C) is supported in two stages on a table 28 that reciprocates from side to side. this table 2
8 is driven by a chain 29, and the supported rolled sheet (C) is sequentially positioned in the supply section of the transfer passage 31.0 In this example, the rolled sheet (C) is supported in two stages, Transfer passages 31 corresponding to the upper and lower stages are provided. Therefore, when the table 28 is moved by the chain 29, the two rolled sheets (C) of the upper and lower stages are located in the supply sections of the upper and lower transfer passages 31, respectively. In this operating state, first, the upper rolled sheet (C) is transported by the unloading device. Next, after all of the upper rolled sheets (C) are sent out, the lower rolled sheets (C) are connected to the ends of the upper corrugated poles and sent out by the delivery device. If the rolled sheet (C) is supported in two stages in this way, the upper rolled sheet (C)
) and the lower rolled sheet (C) are already located in the supply section when the lower rolled sheet (C) is connected, so there is an advantage that the time for the paper splicing process can be shortened. Furthermore, if the upper roll winding sheet (C) and the lower roll winding seam (C) are supported on separate tables 28 and are made to move independently, it is possible to While the sheet (C) is being fed out if, the rolled sheet (C) of the other stage can be positioned in the supply section of the transfer path 31, and this can be done continuously.

FIG. 5 (al (bl) shows still another embodiment of the support body, in which the rolled sheet (C) rotatably supported on the table 28 is placed in a position facing the transfer path 31 by the width shifting plate 15. This width shifting plate 15 is moved laterally by rotating a screw shaft 14 provided at the top of the table 28 with a motor E13. 28. In this example,
The guide plate 11 is pressed by a cylinder E12 as a gripping tool, and the tip of the rolled sheet (C) placed on the entry roller 35 is brought into contact with the entry drive roller 51 and sent out. The cylinder E12 and the guide plate 11 are provided at the end of the table 28 and are activated after the roll sheet (C) has been sent to this position. For this reason, when supporting the rolled sheet (C) on the support shaft, the end of the rolled sheet (C) is
Place it at 0. In this way, table 2 on the right
After all of the 8 roll winding sheets (C) are used, the table 28 is moved to the right by the motor F9. and,
The leading rolled sheet (C) on the left table 28 is moved by the motor F9 until it reaches a position facing the transport path 31, and the rolled sheet (C) is supplied to the transport path 31. The table is fixed in this position, and the width plate 15
The rolled sheet (C) is supplied by the following steps. During this time, the rolled sheet (C) is supported on the table 28 on the right side.

Further, as shown in FIG. 6(a), when the upper rolled sheet (C) is being fed out, the lower rolled sheet (C) may be transported to the joining part 34. good. In this case, the detector 32 detects the end of the upper rolled sheet (C) and stops the feeding device, and the exit roller 33 transports the end to the joining part 34, and the two are connected with the tape 37. Conversely, the lower rolled sheet (C)
When the rolled sheet (C) is being fed out, the upper rolled sheet (C) is transported to the joining part 34 as shown in FIG. 6(b), and the lower rolled sheet (C)
The distal ends of the two are transferred to the joint 34 and connected.

The positioning of the end and tip of the rolled sheet (C) at the joint portion 34 is performed by motors B52 and C53 using a timer.
However, as shown in FIG. 7(a), the upper roll sheet (
C), and the limit switch 55 may be used to position the end of the lower rolled sheet (C). Further, when using a phototube swift, the upper and lower rolled sheets (C) may be shifted in the lateral direction so that they do not overlap, as shown in FIG. 7(b). In this case, the guide A56 is pushed out to position the upper rolled sheet (C) on the leading edge detector 39. Conversely, when positioning the lower rolled sheet (C) on the leading edge detector 38, the guide B57 is pushed out. After detecting the tip, they are returned and connected.

The end portion of (C) may be curled and warped. For this reason, an error occurs in the detection by the end detector 38, and reliable connection may not be possible. Therefore, as shown in FIG. 8, a cover 58 covering the upper surface of at least the coupling portion 34 of the transfer passage 31 is provided to prevent the distal end portion from warping and to perform detection and coupling. Further, as shown in FIG. 9, a cutter 40 for cutting off the end portion of the rolled sheet (C) may be provided. Cutting is performed by detecting the end of the rolled sheet (C) with a cutting position detector 41, stopping the operation of the output roller 33, and then operating the cut cylinder 42. Therefore, the length to be cut is
It is determined by the distance between the position where the cutting position detector 41 is provided and the cutting position detector 41. After cutting the end of the rolled sheet (C) in this way, the drive roller 50
are connected and sent out in the same manner as in the previous embodiment. In this example, the canted portion is discharged by a flapper 43. This flapper 43 is the tenth
As shown in the figure, a part of the transfer passage 31 is made detachable, and is tilted diagonally by a cylinder C44 so that the cut part can be slid down. Of course, the flapper 43 may not be provided and the air may be used to blow it off.

As shown in FIG. 11, the coupling device 36 includes a rolled tape 37, a taping unit 45 equipped with a tape feeding device and a tape cutter, a vacuum pad 47 connected to a vacuum pump 46, and a vacuum pad 47 that moves the vacuum pad 47 up and down. It consists of a cylinder D48 and a cylinder E49 in which the cylinder D48 is located below the coupling part 34. The tape 37 sent out for a certain length from the team pink unit 45 onto the vacuum pad 47 is adsorbed by the vacuum pad 47 and then cut by a tape cutter. Then, the vacuum band 47 that has attracted the tape 37 is lowered, and then the vacuum band 47 of the cylinder 048 is positioned below the joint portion 34 using the cylinder E49. At this position, actuate the cylinder D48 to remove the tape 37 adsorbed to the vacuum band 47 into a sheet (C
) is attached to the end and tip of the In this example, when pasting the tape 37, the buffer 5S for pressing the sheet (C) from above is lowered by the cylinder F60.
