Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a feeding mechanism for feeding an underlaying paper from a roll body on a rolling table prior to rolling a dough and a rolling machine using the same.

  Conventionally, in this type of spreading machine, it is provided at the rear end in the advancing movement direction of the spreading machine main body of the spreading table prior to spreading the fabric by the spreading machine main body moving forward and backward on the spreading table. It is known that the underlaying paper from the rolled body is fed forward toward the advancing movement direction of the spreader main body through the nip between the nips by the pair of delivery rollers of the delivery mechanism. (See Patent Document 1). At this time, the advancing movement direction of the spreader main body is the forward direction of the spread table where the base paper from the roll body at the rear end of the spread table is fed through the nip of the delivery roller.

Then, the underlaying paper to be fed onto the spread table is made of a material that is slippery and slippery, and the spread fabric is placed on the spread table to perform the spread operation on the spread table, and It is sent to the apparatus of the next process in the mounted state. At this time, as a process following the spreading operation, in the case of being subjected to a cutting operation or the like of the cloth by the cutting machine, the cutting table of the cutting machine is configured by the brush surface. For this reason, in order to prevent the cloth from being caught on the brush surface of the cutting table, it is necessary to transfer the cloth from the spreading table to the cutting table in a state of being placed on the base paper. In this case, the underlaying paper fed onto the spread table is subjected to the feeding length and the tip position of the underlaying paper by counting the feeding amount of the underlaying paper by the feed roller with an encoder or measuring the feeding time. Control.
Patent No. 3594665

  However, in the case of an underlayment sheet drawn out between the feed roller nips, slippage may occur between the feed roller nips. In this case, an error occurs in the feeding amount of the base paper, and the accuracy of the feeding length and the tip position of the base paper is lowered.

  In such a case, it is only necessary to be able to accurately detect the leading end position of the base sheet being fed onto the spread table, but because the base sheet is wound around the roll body, the tip of the base sheet is placed on the spread table. There will be a left-over curl that is in the direction of contact. Therefore, for example, when the base material placed on the underlaying paper is moved in the advancing direction on the spreading table and transferred to the device of the next process, the leading end of the underlaying paper is in contact with the spreading table. The leading end of the base paper may be caught in a gap existing between the devices, and the front end of the base paper may be difficult to detect on the spread table. Alternatively, if the table surface from which the base sheet is fed is not provided with a feed mechanism such as a conveyor, there may be a problem that the leading end of the base sheet curls downward due to the friction with the table surface during feeding. Such underlaying mechanism is not limited to being provided in a spreader, but can also be used when delivering the underlayment on the table surface of various devices such as a cutting machine and a labeling device.

  From this point, there is a demand to correct the curling of the underlaying paper and to reliably solve the problems associated with the curling, such as the sticking of the leading end of the underlaying paper and the detection of the leading end.

  The present invention has been made in view of such a point, and the purpose thereof is to correct the curling of the underlaying paper and to reliably solve the problems associated with the curling, and a feeding mechanism and the same. It is to provide the used spreader.

In order to achieve the above object, according to the present invention, prior to spreading the fabric by the spreading machine main body moving forward and backward on the spreading table, the underlayment paper from the roll body supported on the spreading table is the spread table. In the above, it is assumed that the spreader machine is configured to be fed in the advancing movement direction of the spreader main body by the feeding mechanism. The feeding mechanism is provided with a cutting means for cutting the underlaying sheet along with movement in a direction perpendicular to a plane parallel to the spreading table with respect to the advancing movement direction of the spreading machine main body, and the cutting means A correction means provided on the upstream side of the extending direction of the spreading machine main body, and correcting the curl of the underlaying sheet so that the tip of the underlaying sheet cut by the cutting means is separated upward from the spreading table. It is Bei Ete the door.

Furthermore, the correction means is provided on a movable body that moves relative to the spread table, and a protrusion whose tip projects toward the spread table, and the spread table are provided on the tip of the protrusion There has been characterized Rukoto a groove-like recess is pressed in a state of pressing down the vicinity of the front end of said underlay paper from above.

  Further, the movable body may be provided so as to be movable in a direction perpendicular to the advancing movement direction of the spreading machine main body in a plane parallel to the spreading table.

  On the other hand, the movable body may be provided so as to be vertically movable with respect to the spread table.

  Further, the spreader main body includes detection means for detecting the leading end of the dough when spreading the dough on the spread table. The detection means may detect the leading end of the base paper corrected so as to be separated upward from the spread table by the correction means.

On the other hand, as a reference of the present invention, even in the case of the delivery mechanism in which the base paper from the roll body supported on the table is delivered onto the table, the table is parallel to the delivery direction of the base paper. Cutting means for cutting the underlaying sheet along with movement in a direction orthogonal to one another in a flat plane, and a leading end of the underlaying paper which is provided upstream of the cutting means in the delivery direction of the underlaying paper and cut by the cutting means And correcting means for correcting the curl of the base paper so as to be separated upward from the table.

  As described above, in summary, the correction means separates the tip of the underlaying sheet to be cut by the cutting means upward with respect to the spreading table on the upstream side in the advancing movement direction of the spreading machine main body than the cutting means for cutting the underlaying paper. By correcting the curl of the base paper, the front end of the base paper does not come in contact with the spread table. As a result, the leading edge of the underlaying paper is not caught in the gap existing with the device of the next step, and the detection of the leading edge of the underlaying paper on the spread table becomes easy to understand, and the problems associated with curling are reliably ensured. It can be eliminated.

  In addition, pressing the tip of the projection provided on the moving body moving relative to the spread table into the recess of the spread table while pressing the vicinity of the tip of the underlaying sheet from above, the correction means It can be easily configured.

  Further, by movably providing the movable body in a direction orthogonal to the advancing direction of the spreading machine body in a plane parallel to the spreading table, the moving body is parallel to the spreading table with respect to the advancing direction of the spreading machine body. The projection can be made compact without requiring a large projection extending across the entire area in the direction orthogonal to the plane.

  On the other hand, by providing the movable body so as to be movable in the vertical direction with respect to the spreading table, the protrusion is moved downward when correcting the leading end of the underlaying sheet to be separated upward with respect to the spreading table. Therefore, the correction of the base paper by the projection can be performed instantly.

  Furthermore, the spreader main body is provided with detection means for detecting the front end of the cloth, and the detection means detects the front end of the base paper by detecting the front end of the underlaying sheet which is separated upward from the spread table. It is not necessary to provide a new sheet, and the front end position of the underlay can be detected easily and inexpensively using the detection means for detecting the front end of the fabric.

On the other hand, as a reference of the present invention, the leading end of the underlaying paper is on the table even if it corrects the curl of the underlaying paper so that the leading end of the underlaying paper cut by the cutting means There is no contact with As a result, even if the table surface for feeding the underlaying paper is not provided with a feeding mechanism such as a conveyor, the leading end of the underlaying paper will not be curled downward due to the friction with the table surface at the time of feeding. In addition, the leading end of the base paper does not get caught in the gap existing between the apparatus of the next step and the front end of the base paper on the table can be easily detected. Therefore, the subject accompanied by a curl can be eliminated reliably.

And 24. The cutting means 23 includes a disk-shaped rotary blade 231 rotatably supported by the moving body 22 and a block-shaped fixed blade (not shown) whose blade edge is always in sliding contact with the rotary blade 231. . The rotary blade 231 is drivably connected to the shaft of a motor (not shown) and rotates.

  The correction means 24 is provided on the movable body 22 and has a substantially arc-shaped projection 25 whose tip projects downward toward the spreading table 12, and the spreading table 12 across the entire width direction via the housing 21. A groove-like recess 26 is provided, which is provided so that the tip of the protrusion 25 is pressed in a state in which the vicinity of the tip of the base paper D is pressed from above.

  The correction means 24 is provided at a predetermined distance (about 5 to 30 mm) away from the cutting means 23 on the upstream side (right side in FIG. 4) of the advancing movement direction of the carriage 14 and corrects the curl of the underlaying sheet D at that position. The leading end of the underlaying paper D to be cut by the cutting means 23 is spaced upward from the spread table 12. At this time, the curl of the underlaying paper D pressed into the recess 26 by the tip end of the protrusion 25 is creased and corrected on the underlaying paper D, whereby the front end of the underlaying paper D against the spreading table 12 It is made to space up upwards.

  In addition, while the protrusion 25 is formed in a flat plate shape whose tip has the same cross-sectional shape from the base, the recess 26 has an interval of about 3 to 4 times the protrusion 25 in the advancing movement direction of the carriage 14. Are formed by vertical walls facing each other. 3 and 4, reference numeral 27 denotes a presser plate, which presses the underlaying paper D against the spreading table 12 when the underlaying paper D is cut by the rotary blade 231, thereby suppressing deviation at the time of cutting. doing. As shown by the alternate long and short dash line in FIG. 4, the pressing plate 27 presses the leading end of the underlaying sheet D which is going to be separated upward with respect to the spreading table 12 when the underlaying sheet D is corrected by the correction means 24. After the pressing plate 27 passes, the leading end of the underlaying sheet D is separated upward from the spread table 12.

  Further, the carriage 14 is provided with a distance measurement sensor 28 as a detection means for detecting the front end of the material S drawn onto the spread table 12. The distance measurement sensor 28 is provided to measure the height of the tip of the dough S on the spread table 12 to detect that the tip of the dough S has reached. In the present embodiment, the distance measuring sensor 28 is provided to measure the height of the tip of the underlaying sheet D fed onto the spread table 12 and to detect that the tip of the underlaying sheet D has reached. .

  Next, the procedure from the feeding of the underlaying paper D by the spreading machine 1 to the spreading operation of the dough S will be described based on FIGS. 5 and 6. FIG. 5 is an explanatory view showing the procedure of the feeding operation of the base sheet D by the feeding mechanism 20, and FIG. 6 is an explanatory view showing the procedure from the feeding of the base sheet D by the spreading machine 1 to the spreading operation of the fabric S. ing.

  First, as shown in FIG. 6A, the carriage 14 is stopped at the spreading operation start position of the rear end of the spreading table 12 to be in a standby state. At this time, the underlaying paper D is fed from the roll body K through the nip between the rollers 201 and 202 to the rear end of the spreading table 12 and is cut by the rotary blade 231 of the cutting means 23.

  At this time, the underlaying paper D fed out from the roll body K to the rear end of the spread table 12 through the nip between the both rollers 201 and 202 is cut by the rotary blade 231 of the cutting means 23 when the rotary blade 231 is cut. The position near the front end of the underlaying paper D is pressed from above by the front end of the projection 25 of the correction means 24 from the one side in the width direction with the movement of the movable body 22 at a position separated by a predetermined amount It is pushed into the recess 26 in a warped state, and the leading end of the underlaying paper D is corrected to be spaced upward from the spread table 12. In this case, the cutting of the base paper D by the rotary blade 231 of the cutting means 23 and the correction of the base paper D by the correcting means 24 are simultaneously performed.

  Then, as shown in (a) of FIG. 5 and (b) of FIG. 6, the required length of the underlaying sheet is detected so that the distance measurement sensor 28 comes to the tip position where the required length of the underlayment D is obtained. Move forward to the position. Thereafter, the underlaying paper D from the roll body K is passed through the nip between the both rollers 201 and 202, and jointly with the conveyor on the unfolding table 12 the underlaying paper D on the unfolding table 12 in the advancing movement direction of the carriage 14 Feed out. Then, as shown in (b) of FIG. 5 and (c) of FIG. 6, when the distance measuring sensor 28 detects the leading edge of the underlaying sheet D which is fed out onto the spread table 12 in the advancing movement direction, the drive roller 201 and The drive of the conveyor on the spread sheet table 12 is stopped, and the leading end of the base sheet D is stopped at the position for detecting the base sheet required length.

  Thereafter, as shown in (c) of FIG. 5 and (d) of FIG. 6, the carriage 14 is advanced to advance to the planned spreading position of the underlaying sheet D for spreading operation. At this time, the rear end of the underlaying paper D for which the required length is obtained is cut by the rotary blade 231 of the cutting means 23, and the leading end separates the underlaying paper D at the next point following this from the spreading table 12. The correction means 24 corrects the

  Then, the conveyor on the spreading table 12 is driven, and the base paper D is moved in the advancing movement direction on the spreading table 12. Then, as shown in (d) of FIG. 5 and (e) of FIG. 6, when the distance measuring sensor 28 detects the leading edge of the underlaying sheet D moved on the spread table 12 in the advancing movement direction, the spread table The driving of the conveyor on 12 is stopped, and the leading edge of the underlayment D is stopped at the spreading operation scheduled position.

  Thereafter, as shown in (f) of FIG. 6, the carriage 14 is retracted to the spreading start position of the fabric S. Then, as shown in FIG. 6G, the carriage 14 is retracted from the spreading operation start position to perform the spreading operation. At this time, the dough S of a desired length is drawn out from the feeding port 13 onto the spreading table 12, and in this state, when the holder 16 is moved forward along the rail 15, the dough S is cut by a cutting device The dough S is placed on the underlaying paper D of the spread table 12.

  Then, as shown in (h) of FIG. 6, the carriage 14 is advanced to the spreading start position of the fabric S, and then, as shown in (i) of FIG. The fabric S is stacked one by one on the underlaying paper D of the spread table 12 by retracting and repeating the spread operation.

  FIG. 7 is an explanatory view for explaining the position detection of the front end of the base sheet D by the distance measuring sensor 28, wherein (a) is a detection position of the base D without correcting the front end, and (b) is a correction of the front end. The detection positions of the base paper D are shown in the respective states.

  As shown in FIG. 7 (a), the curls remaining on the base paper D wound around the roll body K are in the vicinity of the surface layer (represented by a broken line in FIG. 7) and in the vicinity of the core (represented by a solid line in FIG. 7). A difference has occurred. For this reason, since the distance measuring sensor 28 detects the height (shown by the alternate long and short dash line in FIG. 7), when the front end of the base sheet is in contact with the spread table, detection of the front end of the base sheet D It can be seen that a large difference occurs in the position in the front-rear direction. At this time, the detection position of the underlaying sheet D in the state corrected by the correction means 24 is, as shown in (b) of FIG. It can be seen that there is only a slight gap in the front-rear direction at the detection position of the tip of the. As a result, the detection accuracy of the leading edge of the base sheet D by the distance measurement sensor 28 becomes very high without being affected by the curl.

  Therefore, in the present embodiment, the correction means 24 spreads the tip of the underlaying sheet D to be cut by the rotary blade 231 on the upstream side in the advancing movement direction with respect to the rotary blade 231 of the cutting means 23 for cutting the underlayment sheet D. Since the correction is made to space the table 12 upward, the tip does not touch the spread table 12. As a result, the leading end of the underlaying paper D is not caught in the minute gap existing with the cutting table of the subsequent cutting machine, and the detection of the leading end of the underlaying paper D on the spreading table 12 is easy to understand And the problems associated with curling can be solved with certainty.

  Further, the leading end of the protrusion 25 is pushed into the recess 26 at the rear end of the spreading table 12 with the vicinity of the tip of the underlaying paper D pressed from above, whereby the protrusion 25 and the recess 26 correct the correction means 24. Can be configured easily.

  In addition, since the projection 25 is provided on the movable body 22 movable in the width direction of the carriage 14, a large projection which covers the entire area in the width direction of the carriage 14 is not necessary. Can be implemented.

  Further, a distance measuring sensor 28 is provided on the carriage 14 to measure the heights of the tips of the underlaying paper D and the dough S on the spreading table 12 to detect that the tips of the underlaying paper D and the dough S have reached. Therefore, it is not necessary to newly provide detection means for detecting the leading edge of the base sheet D, and the leading end position of the base sheet D can be detected easily and inexpensively using the distance measurement sensor 28.

  The present invention is not limited to the above embodiment, and includes various other modifications. For example, although the projection 25 of the correction means 24 is provided on the movable body 22 movable in the width direction of the carriage 14 in the above embodiment, the projection of the correction means is provided over the entire width direction of the carriage The projection may be provided on a movable body that can move in the vertical direction with respect to the spreading table. In that case, when correcting the front end of the underlaying sheet so as to separate it upward from the spreading table, the moving body provided with the projection may be advanced downward and the correction of the underlaying paper by the projection can be instantaneously performed. It can be carried out. At this time, the projection does not have to be provided across the entire width of the carriage, and the base sheet may be straightened in at least one of the widthwise ends of the carriage. Is only required to be provided on a movable body that can move up and down with respect to the spreading table.

  In the embodiment, the recess 26 extending in the width direction is provided at the rear end of the spread table 12. However, the elastically deformable urethane resin material is used at the rear end of the spread table 12, and the tip of the protrusion is May be pressed into the urethane resin material while holding the vicinity of the front end of the underlaying paper D from above, and even in that case, the underlaying paper is corrected so that the front end is separated upward from the spreading table. Ru. At this time, the underlaying paper is corrected to be in a creased state if the tip of the protrusion is a relatively thin plate, but the tip of the protrusion is a plate having a thicker end or a cross section If it is formed in a U-shape, when it is immersed in a urethane resin material, it is corrected so that a loose substantially U-shaped bending is inserted.

  In the above embodiment, the leading edge of the base sheet D is detected by the distance measuring sensor 28 provided on the carriage 14. However, a plurality of optical sensors are vertically arrayed and shielded on one side in the width direction of the spreading table. The height of the tip of the base paper may be detected, or a camera may be installed to detect the height of the tip of the base paper by image processing.

  Furthermore, in the above embodiment, the tip of the protrusion 25 is formed in a flat plate shape having the same cross-sectional shape from the base, while the recess 26 is approximately 3 to 4 times as large as the protrusion 25 in the advancing movement direction of the carriage 14. The front end and the recess of the projection may be formed in a substantially V-shaped or substantially U-shaped cross section.

  Further, in the above embodiment, the cutting of the underlaying paper D by the rotary blade 231 of the cutting means 23 and the correction of the underlaying paper D by the correcting means 24 are simultaneously performed. Underlaying sheet cutting and underlaying sheet correction may be performed with a time difference from each other by, for example, creating a mechanical phase difference. At this time, if the correction of the base sheet is delayed as compared with the cutting of the base sheet by the cutting means, it is possible to smoothly separate the tip upward from the spreading table when the base sheet is corrected.

  Moreover, in the said embodiment, although the cutting machine as an apparatus of the following process was continued in a row in front of the spreading table 12 of the spreading machine 1, it is not limited to this, The spreading table of a spreading machine A labeling device as a device of the next process may be continuously provided in front of the device, and even in this case, a minute gap of about several millimeters exists between the table of the labeling device and the spreading table. It is assumed that

  Furthermore, in the present embodiment, the case where the delivery mechanism 20 is used for the spreader 1 has been described, but it is used when delivering the base paper on the table surface of various devices such as a cutting machine and a labeling device It goes without saying that it is good. In that case, the leading edge of the underlaying paper does not touch the table by correcting the curl of the underlaying paper so that the leading edge of the underlaying paper is separated upward with respect to the table. As a result, even if the table surface for feeding the underlaying paper is not provided with a feeding mechanism such as a conveyor, the leading end of the underlaying paper will not be curled downward due to the friction with the table surface at the time of feeding. In addition, the leading end of the base paper does not get caught in the gap existing between the apparatus of the next step and the front end of the base paper on the table can be easily detected. Therefore, it is possible to reliably solve the problems associated with curling.
