Description

  The present invention relates to an apparatus for measuring the width of each roll-like sanitary paper in the middle of a line from cutting to packaging of the roll-like sanitary paper.

  Some roll-type sanitary papers have product widths defined by JIS. For example, in a toilet roll, the product width is defined as 114 mm ± 1 mm. Usually, such roll-like sanitary paper such as toilet rolls and kitchen paper forms a log by winding a predetermined amount of base paper of substantially the same width around a long paper tube in advance. And while conveying this log along the longitudinal direction axis line, after cutting a part located in the conveyance direction most foremost in a cutting process into a predetermined product width by a log cutter, a plurality of rolls in a packaging process Sanitary paper is packaged in an aligned state and shipped as a product. Patent Document 1 discloses a line from such cutting to packaging.

  It is known that the width dimension of the roll-like sanitary paper cut by the log cutter in the cutting process changes depending on the sharpness of the log cutter, that is, the worn state of the cutting blade and the variation in the outer diameter of the log. As a general tendency, the width dimension of the roll-like sanitary paper increases with a decrease in the sharpness of the log cutter, and the width dimension of the roll-like sanitary paper decreases as the outer diameter of the log decreases.

  Conventionally, the management of the width dimension of a roll-like sanitary paper is carried out by periodic sampling inspections rather than full inspections. For this reason, there existed a problem that the roll-shaped sanitary paper which has a dimension outside a specification, such as the edge part of a log which cannot be used as a product, was carried out to the packaging process. Therefore, an inspection apparatus proposed in Patent Document 2 for the purpose of inspecting the entire width of the roll-like sanitary paper is known.

JP 2010-63796 A Japanese Patent No. 3643352

  In the inspection apparatus disclosed in Patent Document 2, a step is formed on two adjacent conveyors to change the conveyance posture of the roll-like sanitary paper by 90 degrees. However, this method is not reliable with respect to the change in the transport posture of the roll-like sanitary paper that is transported at high speed, and may cause an erroneous inspection result in a state where the posture is not changed. Moreover, it is necessary to slightly change the steps and inclination angles of the two conveyors according to the conveyance speed of the roll-like sanitary paper, and there is a problem that the setup work is very complicated.

  The object of the present invention is to reliably change the transport posture of roll-like sanitary paper in any transport speed range, and to measure the width dimension of each roll-like sanitary paper automatically and with high reliability. The object is to provide an apparatus capable of this.

A roll sanitary paper dimension measuring apparatus according to the present invention comprises a bottom wall that rotates at a predetermined speed around a horizontal axis and receives one end surface in the width direction of a cylindrical roll sanitary paper, and a peripheral wall surrounding the bottom wall. A plurality of buckets each having a roll-like sanitary paper, each having a radial position, a roll-in sanitary paper input position, a measurement position at which the width of the roll-like sanitary paper is measured, and a measurement The position where the discharge position where the roll-shaped sanitary paper is discharged after the end is set along the rotation direction and the position of the other end surface in the width direction of the roll-shaped sanitary paper housed in the bucket at the measurement position comprising a sensor for detecting peripheral wall of the bucket has a pair of opposed side walls along the rotational axis of the rotor, and a pair of partition walls facing each other along the rotational direction of the rotor The base end portions of the pair of partition walls positioned on the rotation axis side of the rotor are attached to the rotor so as to be swingable about an axis parallel to the rotation axis of the rotor, and the measurement position is from the charging position. The roll-shaped sanitary paper housed in the bucket in the rotational direction of the rotor is a position leaning against the partition wall located on the rear side in the rotational direction of the rotor. is there.

  In the present invention, the roll-like sanitary paper is put into the bucket at the loading position, and one end surface in the width direction of the roll-like sanitary paper is placed on the bottom wall of the bucket. Then, when the roll-like sanitary paper reaches the measurement position as the rotor rotates, the position of the other end surface in the width direction of the roll-like sanitary paper contained therein is detected by the sensor. The roll-like sanitary paper whose width dimension has been detected is discharged out of the bucket at the discharge position with the further rotation of the rotor.

  In the dimension measuring apparatus for rolled sanitary paper according to the present invention, the bottom wall of the bucket is formed on a flat surface parallel to the rotation axis of the rotor, and the measurement position is the width direction of the rolled sanitary paper accommodated in the bucket. It may be a position where the end face is upward and horizontal.

In this case, the partition wall can be set to rotate within a range of a predetermined angle on the front side in the rotation direction of the rotor from a virtual plane including the rotation axis of the rotor and the swing axis of the base end portion of the partition wall. .

  A plurality of roll-like sanitary papers are transported along a direction parallel to the longitudinal axis in a state where the longitudinal axes thereof are arranged at a predetermined interval so that the longitudinal axes thereof are in a straight line. Receiving the roll-like sanitary paper into the bucket and the roll-like sanitary paper discharged from the bucket that has reached the discharge position so that the longitudinal axis of the roll-like sanitary paper is in a straight line And a carry-out conveyor for carrying it out of the rotor along a direction parallel to the longitudinal axis thereof.

According to the roll-size sanitary paper dimension measuring apparatus of the present invention, the roll-type sanitary paper can be reliably accommodated in a predetermined posture by using a rotor provided with a plurality of buckets in a radial manner. It becomes possible to measure accurately and continuously. In addition, since the base end of the partition wall that constitutes a part of the peripheral wall of the bucket located on the rotation axis side of the rotor is attached to the rotor so as to be swingable about an axis parallel to the rotation axis of the rotor, The wall inclination can be automatically changed according to the rotational phase of the rotor. Furthermore, since the measurement position is set to a position where the roll-like sanitary paper is leaning against the partition wall located on the front side in the rotor rotation direction and the rear side with respect to the rotor rotation direction from the loading position, Measurement of the width dimension can be performed in the same stable posture.

  When the bottom wall of the bucket is formed with a flat surface parallel to the rotation axis of the rotor, and the measurement position is set to a position where the other end surface in the width direction of the roll-like sanitary paper stored in the bucket is upward and horizontal, The width dimension of the roll-like sanitary paper can be measured in a stable state.

  When the partition wall is set to rotate within a predetermined angle range from the imaginary plane including the rotation axis of the rotor and the swing axis of the base end of the partition wall in the rotational direction of the rotor, the roll shape with respect to the bucket Sanitary paper can be carried in and out more reliably.

  When the conveyor bucket is further equipped with a carry-in conveyor for carrying in the roll-like sanitary paper and a carry-out conveyor for carrying it out, the width of the roll sanitary paper in the middle of the line from cutting to packaging Dimensions can be measured continuously and accurately.

In embodiment shown in FIG. 7, it is sectional drawing of the side shape which shows the state which has a roll-shaped sanitary paper in a measurement position.

  A first embodiment in which the roll sanitary paper size measuring device according to the present invention is applied to a toilet roll to be packed will be described in detail with reference to FIGS. In addition, although this embodiment is drawn as a system that processes two logs (see FIG. 6), that is, two rows of rolled sanitary paper in parallel, a system that processes three or more logs in parallel, It goes without saying that the present invention can be applied even to a system that processes only one log.

  The dimension measuring apparatus in this embodiment is schematically shown in FIG. 1, the side shape of the main part is enlarged and shown in a sectional state in FIG. 2, and the planar shape is shown in FIG. That is, the dimension measuring apparatus 10 according to the present embodiment is arranged on the upstream side and the downstream side of the rotor 11, the sensor 13 for measuring the width of the cylindrical sanitary paper sheet 12, and the rotor 11. A carry-in conveyor 14 and a carry-out conveyor 15.

The rotor 11 is connected to a drive motor (not shown) and rotates around a horizontal axis at a predetermined speed. In the rotor 11, a plurality (five in the illustrated example) of buckets 16 that can accommodate the roll-like sanitary paper 12 are provided radially at equal intervals along the rotation direction of the rotor 11. Individual bucket 16 has a bottom wall 16a for receiving the widthwise end surface (the conveyance direction front side facing surface) 12 _F of the rolled sanitary paper 12, a peripheral wall 16b forming a truncated pyramid shape surrounding the bottom wall 16a, and 16c Respectively. The bottom wall 16a is formed at the rotation axis parallel to the flat surface of the rotor 11, thereby being adapted to the width direction end face 12 _F of the rolled sanitary paper 12 can be stably supported. The dimension shape of the bottom wall 16a is a rectangle that is slightly larger than the diameter of the roll-like sanitary paper 12, and the distance between the pair of peripheral walls 16b facing each other along the rotation direction of the rotor 11 increases as the distance from the rotation center of the rotor 11 increases. , These intervals are set to widen. On the other hand, the distance between the pair of peripheral walls 16 c facing each other along the rotation axis of the rotor 11 is set to be slightly larger than the diameter of the roll-like sanitary paper 12. Thereby, the roll-shaped sanitary paper 12 can be smoothly charged into and discharged from the bucket 16 to be described later, and discharged from the bucket 16 to the carry-out conveyor 15. It is considered to be retained. The distances from the rotation axis of the rotor 11 to the bottom walls 16a of the individual buckets 16 are all set equal, and the heights of the peripheral walls 16b and 16c from the bottom wall 16a are lower than the width dimension of the roll-like sanitary paper 12. Is set.

The rotor 11, the loading position P _I of rolled sanitary paper 12 is turned on, and the measurement position P _S where the width dimension of the rolled sanitary paper 12 is measured, rolled sanitary paper 12 is measured after completion of release a discharge position P _O being is set along the rotational direction. These positions P _I , P _S , and P _O are closely related to the carry-out end of the carry-in conveyor 14, which will be described later, the sensor 13, and the carry-in end of the carry-out conveyor 15. Here, the state of the roll-like sanitary paper 12 at the loading position P _I and the discharge position P _O of the rotor 11 is schematically shown in FIG. 4, and the roll-like sanitary paper 12 on the way from the feeding position P _I to the measurement position P _S is shown. This state is schematically shown in FIG.

The sensor 13 is provided on the other end surface in the width direction of the roll-like sanitary paper 12 housed in the bucket 16 at the measurement position P _S (see FIGS. 1 to 3) where the bottom wall 16a is upward and horizontal, that is, on the upper end surface _12R . Detect position. In the sensor 13 in the present embodiment, the upper and lower two light projecting portions 17 _U and 17 _L and the light receiving portions 18 _U and 18 _L are arranged immediately above the rotor 11 along a direction parallel to the rotation axis of the rotor 11. . More specifically, the detection light (not shown) emitted from the upper and lower light projecting units 17 _U and 17 _L toward the light receiving units 18 _U and 18 _L is positioned in a vertical plane including the rotation axis of the rotor 11. It arrange | positions so that a pair of surrounding wall 16c which opposes along the rotating shaft line of the rotor 11 may be pinched. The distance from the rotation axis of the rotor 11 to the two upper and lower detection lights is the sum of the distance from the rotation axis of the rotor 11 to the bottom wall 16a and the minimum and maximum values of the width dimension of the roll-like sanitary paper 12. Is set to be equal to. That is, the upper and lower light projecting portions 17 _U and 17 _L and the light receiving portions 18 _U and 18 _L are distances from the rotation axis of the rotor 11 in association with the maximum allowable tolerance and the minimum allowable tolerance of the width dimension of the roll-like sanitary paper 12. Is set.

Accordingly, when the upper and lower light receiving portions 18 _U and 18 _L detect the detection light in a state where the rolled sanitary paper 12 is at the measurement position P _S , it can be determined that the width of the rolled sanitary paper 12 is too narrow. it can. Further, when the upper and lower light receiving portions 18 _U and 18 _L cannot detect the detection light in a state where the roll-like sanitary paper 12 is at the measurement position P _S , it may be determined that the width of the roll-like sanitary paper 12 is too long. it can. When only the upper light receiving unit 18 _U detects the detection light in a state where the roll-like sanitary paper 12 is at the measurement position P _S , it is determined that the width dimension of the roll-like sanitary paper 12 is within the tolerance range. Can do. Thus, the roll-like sanitary paper 12 at the measurement position P _S has its entire lower end surface 12 _{F in contact with} the bottom wall 16 a of the bucket 16, and its center axis is accurately vertical. It is always possible to accurately grasp whether or not they are within the same posture.

The carry-in conveyor 14 conveys a plurality of roll-like sanitary papers 12 in a state parallel to the longitudinal axis in a state where the longitudinal axes are arranged at predetermined intervals so that the longitudinal axes are aligned. Further, rolled sanitary paper 12 to the bucket 16 located at unloading end of the input conveyor 14 to the loading position P _I must to be carried. For this reason, the position of the carry-out end of the carry-in conveyor 14 with respect to the rotor 11, the rotational phase of the bucket 16 of the rotor 11, and the relative position of the rolled sanitary paper 12 on the carry-in conveyor 14 are appropriately set. In this embodiment, the carry-in conveyor 14 as rolled sanitary paper 12 is smoothly turned against the bucket 16 in the loading position P _I, the bucket 16 in the loading position P _I from the carry-out end of the input conveyor 14 An insertion guide plate 19 that is inclined downward toward the nearest is arranged.

Thus, in this embodiment, the roll-like sanitary paper 12 on the carry-in conveyor 14 is transferred to the bucket 16 of the rotor 11 using gravity. However, it may be transferred to the bucket 16 of the rotor 11 in a rolled sanitary paper 12 that has reached the unloading end of the input conveyor 14 by a known handling device in loading position P _I.

Similarly to the carry-in conveyor 14, the carry-out conveyor 15 also has a plurality of roll-like sanitary papers 12 arranged at predetermined intervals so that the longitudinal axes thereof are aligned with each other in a direction parallel to the longitudinal axis. Convey along. As the rolled sanitary paper 12 accommodated in the bucket 16 in the discharge position P _O at loading end of the discharge conveyor 15 is placed, the position of the loading end of the discharge conveyor 15 for the rotor 11 is properly set .

The carry-out conveyor 15 is driven synchronously with the carry-in conveyor 14 together with the rotor 11, but it is not necessary to match the conveyance speed of the roll-like sanitary paper 12 with the conveyance speed of the roll-like sanitary paper 12 by the carry-in conveyor 14. For example, by making the transport speed of the carry-out conveyor 15 slower than the transport speed of the carry-in conveyor 14, the interval between the roll-like sanitary papers 12 arranged along the transport direction can be set narrower. Moreover, it is also possible to use a known handling device instead of transferring the roll-like sanitary paper 12 accommodated in the bucket 16 of the rotor 11 onto the carry-out conveyor 15 using gravity. In this case, it may be transferred to loading end of the discharge conveyor 15 a rolled sanitary paper 12 accommodated in the bucket 16 in the discharge position P _O by the handling device.

  A cutting unit 21 having a log cutter 20 as shown in FIG. 6 is connected to the upstream side of the carry-in conveyor 14, and a predetermined number of the cut roll-like sanitary paper 12 is provided downstream from the carry-out conveyor 15. A packaging portion (not shown) for bundling and packaging with a resin film or the like is connected.

Log 12L elongated having a cylindrical shape, toward the cutting position P _C is its unloading end by a log conveyor (not shown), it is transported along a direction parallel to its longitudinal axis. The log cutter 20 disposed at the cutting position P _C includes a rotary arm 22 driven and rotated by a drive motor (not shown), and a cutting blade 23 having a disk shape that is rotatably attached to both ends in the radial direction of the rotary arm 22. And have. Each of the cutting blades 23 is also provided with a driving motor (not shown) for driving and rotating the cutting blades 23. That is, the leading end portion in the conveyance direction of the log 12L that has reached the cutting position P _C is moved so that the cutting edge 23 crosses the longitudinal axis of the log 12L by a combination of the rotation of the cutting edge 23 and the rotation of the rotary arm 22. Then, it is cut and sent to the carry-in conveyor 14. In this case, since the transport speed of the carry-in conveyor 14 is set higher than the transport speed of the log 12L, the cut roll-like sanitary paper 12 is arranged in the state of being spaced along the transport direction. It is conveyed to.

Accordingly, the log 12L having a long cylindrical shape is transported by a log transport conveyor (not shown) along a direction parallel to the longitudinal axis. Then, predetermined by the cutting edge 23 of the log cutter 20 conveying direction leading end of the rolled sanitary paper 12 elongated reaches the cutting position P _C is moved transversely to the conveying direction of the rolled sanitary paper 12 Cut to dimensions. The individual roll-shaped sanitary paper 12 that has been cut is conveyed toward the rotor 11 along the direction parallel to the longitudinal axis thereof, with the cut surfaces 12 _F and 12 _R being spaced apart by the carry-in conveyor 14. Rolled sanitary paper 12 that has reached the unloading end of the input conveyor 14 is turned on via the turned guide plate 19 to the bucket 16 of the rotor 11 has reached the loading position P _I. The roll-like sanitary paper 12 placed in the bucket 16 is held at the measurement position P _S of the rotor 11 so that the cut surfaces, that is, the widthwise end faces 12 _F and 12 _R face the up and down direction. The position of the cut surface 12 _R is detected by the sensor 13. Then, whether the width of the rolled sanitary paper 12 in accordance with the detected position of the cutting plane 12 _R is within a predetermined tolerance is determined.

  In this embodiment, when the determination that the width dimension of the roll-like sanitary paper 12 detected by the sensor 13 is smaller than the minimum tolerance, that is, the width dimension is too small, is continued twice and the log is stopped. Replace 12L. In short, in this case, it is determined that the width of the roll-like sanitary paper 12 has become narrow because the diameter of the log 12L is too small, and the log 12L having a larger diameter is replaced with a log 12L having a higher density or the same diameter. Is done. In addition, since the roll-like sanitary paper 12 accommodated in the bucket 16 of the rotor 11 and the roll-like sanitary paper 12 on the carry-in conveyor 14 are likely to have non-standard width dimensions, these are also excluded from the line. .

  If the width dimension is judged to be too small, it is due to the first cutting of the long log 12L, so only the non-standard roll-like sanitary paper 12 is excluded from the bucket 16 of the rotor 11. It is only necessary to replace the log 12L.

  Conversely, the line is also stopped when it is determined that the width dimension of the rolled sanitary paper 12 detected by the sensor 13 is larger than the maximum tolerance, that is, the width dimension is too large. However, in this case, it is determined that the sharpness of the log cutter 20 has deteriorated, and the cutting edge 23 of the log cutter 20 is re-polished or replaced with the polished log cutter 20 and the line is activated again.

When the width dimension of the roll-like sanitary paper 12 is within the allowable tolerance, the operation is continued without stopping the line. Such rolled sanitary paper 12 width is measured in the is unloaded from the measuring position P _S to the discharge position P _O of the rotor 11, is transferred to the loading end of the discharge conveyor 15. The carry-out conveyor 15 conveys the rolled sanitary paper 12 toward the packaging unit along a direction parallel to the longitudinal axis.

  In the above-described embodiment, the plurality of buckets 16 are fixedly arranged with respect to the rotor 11, but the base end portion of the peripheral wall 16 b facing the rotor 11 in the rotational direction is pivotally supported with respect to the rotor 11. It is also possible.

  The schematic structure of another embodiment of the present invention is shown in FIGS. 7 and 8, but the same reference numerals are given to elements having the same functions as those of the previous embodiment, and duplicate descriptions are omitted. 7 and 8 show a state in which the rotation phase of the rotor 11 is shifted by half the arrangement interval of the buckets 16. The peripheral wall of the bucket 16 in the present embodiment has a pair of continuous annular walls (not shown) that face each other along the rotation axis O of the rotor 11 and a pair of partition walls 16 d that face each other along the rotation direction of the rotor 11. . The base end portion of the partition wall 16d positioned on the rotation axis O side of the rotor 11 is arranged on the radially inner side with respect to the outer peripheral surface 11a of the cylindrical rotor 11, and each axis S is parallel to the rotation axis O of the rotor 11. It is attached to the rotor 11 so as to be able to swing around. Therefore, rectangular openings 11b for allowing the partition wall 16d to swing are formed on the outer circumferential surface 11a of the rotor 11 at regular intervals along the circumferential direction. In the present embodiment, the partition wall 16d is within a range of a predetermined angle σ on the front side in the rotational direction of the rotor 11 from a virtual plane F including the rotation axis O of the rotor 11 and the swing axis S of the base end portion of the partition wall 16d. It is set to rotate. However, the range of the rotatable angle σ of the partition wall 16d and the relative position along the circumferential direction of the opening 11b with respect to the swing axis S are not limited to the present embodiment and can be arbitrarily set. It is.

The swinging position of the partition wall 16d automatically changes continuously from its own weight according to the rotational phase of the rotor 11 with respect to the rotational axis O. At the same time, in a state where the roll-like sanitary paper 12 is housed in the bucket 16, the roll-like sanitary paper 12 swings in the bucket 16 as the rotor 11 rotates. Specifically, the rolls are rolled according to the position of the center of gravity of the roll-like sanitary paper 12 and the contact position of the bottom wall of the bucket 16, that is, the end surface 12 _{F in} the width direction of the roll-like sanitary paper 12 with respect to the outer peripheral surface 11 a of the rotor 11. The sanitary sanitary paper 12 swings in the bucket 16 along the rotation direction of the rotor 11. As a result, the rolled sanitary paper 12 is on position P _I side tends to bear against the surface of the partition wall 16d facing the direction of rotation front side of the rotor 11. On the other hand, on the discharge position _PO side, the roll-like sanitary paper 12 tends to lean against the surface of the partition wall 16d facing the direction opposite to the rotation direction of the rotor 11.

Measuring position P _S in the present embodiment, the partition of the rotation direction front side and rolled sanitary paper 12 accommodated in the bucket 16 of the rotor 11 than the loading position P _I is located on the rear side with respect to the rotation direction of the rotor 11 The position leans against the wall 16d. Therefore, the light projecting portions 17 _U and 17 _L and the light receiving portions 18 _U and 18 _L of the sensor 13 for measuring the width dimension of the cylindrical roll-shaped sanitary paper 12 (only one is shown in FIGS. 7 and 8). ) And the vertical position are also tilted with respect to the vertical line as shown. Thus, a portion of the widthwise end surface 12 _F with pressed against the partition wall 16d positioned on the rear side with respect to the rotation direction of the rotor 11 the outer circumferential surface by its own weight of the rolled sanitary paper 12 in the measuring position P _S Is held in contact with the outer peripheral surface 11 a of the rotor 11. That is, since the sensor 13 measures the width dimension of the roll-like sanitary paper 12 held in such a constant posture at the measurement position P _S , a highly reliable measurement result can be obtained.

Conveying surface of the input conveyor 14 in this embodiment is set diagonally downward inclination with respect to the input position P _I, so that it is possible to further smoothly perform the delivery of the rolled sanitary paper 12 to the bucket 16 from the carry-in conveyor 14 Consideration. Similarly, the transport surface of the carry-out conveyor 15 in this embodiment is set to be inclined obliquely upward with respect to the discharge position _PO , and the roll-like sanitary paper 12 is transferred from the bucket 16 to the carry-out conveyor 15 more smoothly. It is considered to be able to.

  In the present embodiment, by adopting such a configuration, the roll-like sanitary paper 12 is more smoothly transferred between the carry-in conveyor 14 and the carry-out conveyor 15 and the bucket 16 of the rotor 11 than in the previous embodiment. Can be done.

  It should be noted that the present invention should be construed only from the matters described in the claims, and in the above-described embodiment, all the changes and modifications included in the concept of the present invention are other than those described. Is possible. That is, all matters in the above-described embodiment are not intended to limit the present invention, and include any configuration not directly related to the present invention.
