Description

  The present invention conveys the number of supply rows forming a set of product groups by reducing the number of conveyance rows while conveying various products such as a plurality of roll-shaped articles in a plurality of rows by a conveyance means such as a conveyor. The present invention relates to a reduced column type product supply apparatus.

Conventionally, as this type of reduced-column product supply device, for example, there is one described in Patent Document 1 below.
This product supply device stops the biscuits in a process of transporting along a plurality of rows of transfer paths, puts the plurality of biscuits into a stacked state by a stopper provided in each row, and regulates the transfer order. The next linear vibratory feeder is constituted by a reduction train transition portion and a reduction track portion excluding the partition between the tracks in each row. It is said that biscuit will be supplied to the next process at low cost and high efficiency by repeating the same reduction.
Further, in a conventional reduced-column-type product supply apparatus that packs a plurality of rows of toilet paper while transporting them, for example, the toilet paper rows separated into four rows are reduced to three rows, so that one or two rows are provided. 2. Description of the Related Art A packaging device that wraps a toilet paper group stacked in stages is known. In the toilet paper reduction type supply device in this apparatus, as shown in FIG. 14, for example, all the toilet paper groups in the four rows are temporarily stopped for the four toilet paper groups to be supplied, and then the previous stop in the four rows is performed. The conveyance timing was adjusted by simultaneously starting only three rows including the one row.
Japanese Patent Laid-Open No. 7-144745

However, both the product supply device described in Patent Document 1 as the former and the reduced-column type supply device as the latter both stop only all of the product rows and then only recycle the necessary product rows. Since it is the structure which starts and carries out a reduction | decrease conveyance, the product conveyance speed in a product conveyance process became slow, and there existed a malfunction that manufacturing efficiency was inferior. Once the product is stopped and then restarted, if the increase / decrease acceleration is increased in order to recover the transport delay due to the temporary stop, some or all of the product being transported will slip and each product in the subsequent process There arises a problem that the conveyance and stop timing of the row shifts.
In this case, when packaging after reducing transport, the product stop position of each row will be shifted, and it will not be possible to carry out clean packaging with good appearance, or some products may protrude from the packaging film. There were problems such as being unable to do so. Even in this case, there is a problem that the manufacturing efficiency such as the packaging efficiency is inferior.

  In view of such circumstances, the present invention provides a reduced-column-type product supply device that can efficiently transfer to the next process by reducing the number of products that are conveyed in a plurality of rows without stopping all of the products. The purpose is to do.

The reduced-column-type product supply apparatus according to the present invention includes a first transport unit provided with a plurality of rows of supply paths for transporting a plurality of products, and a second transport including a plurality of carry-out paths for receiving the products of the supply paths. And a control conveyor that is provided in each supply path and sends the product in each supply path to the carry-out path side of the second transport section, and the product sent out from the supply path by the control conveyor is carried out at a higher speed than the control conveyor. A speed increasing conveyor for transferring to the road, and stopping a part of the product conveyed through the supply paths of the first conveying section by the control conveyor and delivering the products of other supply paths to the second conveying section. And a reduced-type product supply device that transfers the product of the other supply path to the second carry-out path while changing a part of the supply path for stopping the product in the first transfer unit, Any of the first transport units Stop train judgment means for making a drive stop judgment of the product on the road and outputting a stop signal of the control conveyor; drive stop means for stopping a preset product to be stopped ahead of the time when the stop signal is generated; A detection sensor which is provided in each supply path of the first transport unit and detects that each product is in a stopped state or a transport state, and a control conveyor in each supply path of the first transport unit by a signal from the detection sensor The relationship between the start availability check means for judging whether or not the product can be started, the control conveyor information of the supply path of the product to be stopped next time output from the stop train judgment means and the start signal of the control conveyor confirmed by the start availability confirmation means and a startup sequence determination means for setting a control conveyor supply channel product should stop control conveyor and the next supply passage of the product to be activated next from of launch the product in the stopped state When that product of the stopped state is activated by the control conveyor at a timing earlier than the other products being continuously transported to another supply path, the second from the first conveying unit in synchronization with the product of another supply channel It is characterized by being transferred to the transport unit.
According to the present invention, the products transported in the plurality of supply paths of the first transport section are transferred to the respective transport paths of the second transport section while being reduced, so that the products in the other supply paths are not stopped. The product can be transferred from the first transport unit to the second transport unit at high speed, and at that time, the previously stopped product is caught up with the continuously transported product by starting it earlier than the continuously transported product. Can be delivered synchronously with the second transport path.
Then, by stopping some products in the transport state in other supply channels in connection with the activation of the product in the previous stop state, the necessary number of rows of products to be transported in the reduced state while replacing the products to be reduced Can be reliably secured, and products can be delivered efficiently at high speed by continuous conveyance.
In addition, the activation sequence determination means determines whether or not the activation signal of the control conveyor provided in the supply path of the product to be activated from the stop state can be activated in response to the preset information of the control conveyor of the supply path of the product to be deactivated next time. If it can be confirmed by the confirmation means, the control conveyor for the product to be stopped set in advance is stopped and the control conveyor in the supply path of the product to be activated is started.
In this way, after confirming the start signal of the control conveyor scheduled to start from the stop state, it is determined whether to drive or stop the control conveyor of the product supply path to be stopped next time, so the number of product rows to be conveyed in the reduced state And one set of products can be transported reliably.
In addition, if the activation signal cannot be confirmed, the conveyance of the product scheduled to be stopped is not stopped, that is, the control conveyor is not stopped. Can be secured and continuous conveyance can be executed for one set of product groups.

Further, a pusher member that pushes out the product transferred to each carry-out path of the second transfer unit is provided, and the product stopped by the drive stop means is in the vicinity of the speed-up conveyor by the stop after the control conveyor is decelerated. Therefore, it is preferable to stop at a position where it does not interfere with the pusher member.
Products that are continuously transported without stopping and products that are transported in synchronization with products that are started and accelerated from a stopped state at an earlier timing than these products and that are continuously transported are the supply paths of the first transport unit. Is sent out by the control conveyor, and is transferred to each carry-out path of the second transfer unit at a higher speed by the speed-increasing conveyor to be separated from the subsequent product. On the other hand, the product to be stopped is stopped and held on the supply path that does not interfere with the pusher member in the vicinity of the speed increasing conveyor by the deceleration stop of the control conveyor. Therefore, when a stopped product starts up in the next process from the supply path, it can catch up with other products that are continuously accelerated by accelerating the product to the extent that slip does not occur without rapidly accelerating, The product can be transported smoothly synchronized with the continuous supply line of products. The processing operation can be continuously and smoothly executed while sequentially changing the supply path of the product to be stopped and started.

Further, a circuit that holds the pusher member and moves the product transferred to the second transport unit through the space between the first transport unit and the second transport unit and moved further forward by the pusher member. Means, a detection sensor which is arranged downstream of each control conveyor and detects the passage of the product in each supply path, and the rotation angle of the pusher member by the rotation means corresponding to the detection signal of the product by the detection sensor Detecting and detecting the product by means of a synchronous sensor, which detects and synchronizes the pusher member to synchronize the product transported on each carry-out path of the second conveyance path so as to push the product, and the detection sensor. Drive stop means for detecting the turning angle of the pusher member by the turning means in response to the signal and correcting the deceleration speed by the control conveyor that decelerates the product to be stopped. It is preferred.
According to the present invention, when the product is transferred from the first transport unit to the second transport unit, the pusher member that circulates by the circulating means has the product on each supply path of the first transport unit transferred to the second transport unit. After that, the product on each carry-out path of the second transport unit is pushed and chased. When there is a deviation in the circular motion of the control conveyor or speed-up conveyor for the product conveyance and the pusher member, the speed of the control conveyor is corrected by the synchronization operation means so that the product and the pusher member are synchronized without interference. adjust. Moreover, when the product stops, the product can be stopped at a position where it does not interfere with the pusher member by correcting the deceleration speed of the control conveyor to be stopped by the drive stop means.

Further, the first transport unit may be provided with a detection sensor for detecting a product on each supply path, and the control conveyor may be activated when the detection sensor maintains a detection state for a predetermined time. .
After confirming that the product is continuous or continuously conveyed in the supply path, the control conveyor is driven to convey the product. As a result, the products can be continuously reduced and conveyed.
Each time after the product reduction transfer is turned off, each set of product groups located in the plurality of supply paths selected by the first transfer unit is transferred to the second transfer unit by the drive control means. It is preferable to end the operation of the control conveyor of the supply path.
When product row transfer is turned off, if all control conveyors are turned off at that time, a part of a set of product groups may remain in the supply path, so these may end. The product is stopped after being transferred to the second transport section.

According to the reduction-type product supply device according to the present invention, in each supply path of the first transfer unit, the product that is intermittently transferred by the stop and start and the product that is continuously transferred are sequentially changed and sequentially synchronized. In addition, since it can be transferred to the second transport section, the operation speed can be efficiently supplied to the next process at a higher speed than the conventional apparatus. In addition, the required number of products to be transported in the reduced state can be ensured while replacing the products to be reduced by stopping the products in the supply state in other supply paths in connection with the activation of the previously stopped product. The product can be delivered at high speed and efficiently by continuous conveyance.
In addition, after confirming the start signal of the control conveyor that is scheduled to start from the stop state of some products, it is determined whether to drive or stop the control conveyor of the product supply path that should be stopped next time. The number of product rows to be performed and the number of products in one set can be reliably conveyed.
In addition, if the activation signal cannot be confirmed, the conveyance of the product scheduled to be stopped is not stopped, that is, the control conveyor is not stopped. Can be secured and continuous conveyance can be executed for one set of product groups.

A reduced column type product supply apparatus 1 shown in FIG. 1 is a device that conveys various products, for example, toilet paper P, while decreasing the number of products, and in the next process, for example, packs a set of a plurality of toilet paper P columns. is there. In the reduced column type product supply apparatus 1 shown in FIG. 1, for example, three rows, that is, three toilet papers P connected in series are reduced from four columns to three columns to obtain nine toilet papers of 3 rows × 3 columns. Packed in the next process as a set of P arranged in one row. Instead of this, 18 sets of 2 stages may be set as one set, or 8 sets of 2 rows × 2 columns × 2 stages may be set as one set. The number of rows, the number of columns, the number of stages, and the total number of sets The number is arbitrary.

The reduced-column-type product supply device 1 is a continuous supply conveyor (hereinafter simply referred to as a conveyor) 2 in which a plurality of rows, for example, four rows of conveyors 2a, 2b, 2c, and 2d constituting substantially parallel supply paths are arranged. One transport unit 3, four rows of substantially parallel carry-out passages 4a, 4b, 4c, 4d, a reduction row 5 in which these are reduced to three rows in the middle, and a reduced-column carry-out in which these three rows are integrated And a second transport unit 7 composed of a path 6. In the 1st conveyance part 3, the partitions 8 and 8 are provided in the both sides for each conveyor 2a, 2b, 2c, 2d.
Each of the conveyors 2a, 2b, 2c, and 2d is basically kept in an always operating state by using the motor M3 as a driving source. A pair of control conveyors 10 and 10 are provided on both sides of the downstream sides of the conveyors 2a, 2b, 2c, and 2d so as to sandwich the toilet paper P that is conveyed in contact with each other. Controls switching between speed setting and stop. Each pair of control conveyors 10 is disposed so that the distance between the pair of control conveyors 10 becomes narrower toward the front so as to have a substantially C shape, and the front end portion protrudes from each conveyor 2 (see FIG. 2).
And in the 1st conveyance part 3, the pool sensor 11, the lower limit sensor 12, and the detection sensor 13 are sequentially located above each conveyor 2a, 2b, 2c, 2d from the conveyance direction upstream of the toilet paper P toward the downstream. Is provided. The pool sensor 11 and the lower limit sensor 12 together with the timers 11a and 12a detect that the toilet paper P is positioned or continuously conveyed on the conveyors 2a, 2b, 2c and 2d, respectively. The detection sensor 13 detects the front end of the toilet paper P protruding in front of the control conveyors 10 and 10.

Next, in the second transport unit 7, partitions 15 and 15 are provided on both sides of the carry-out paths 4a, 4b, 4c, and 4d, respectively. A pair of speed-increasing conveyors 14 and 14 sandwiching both sides of the toilet paper P in each row to be transported are provided upstream of the carry-out paths 4a, 4b, 4c, and 4d, and are transported by the control conveyors 10 respectively. Each toilet paper P that has been received is received and transported from the unloading paths 4a to 4d to the reduction path 5 at a higher transport speed.
As a result, a gap S is formed between the toilet paper P at the front end sandwiched between the control conveyors 10 and 10 in each row and the toilet paper P sandwiched between the speed-increasing conveyors 14 and 14 (see FIG. 1).

Each speed-increasing conveyor 14 is arranged in a substantially square shape whose interval narrows toward the front in the transport direction in plan view. And the control conveyor 10 in the state which the front-end | tip of 1 row of toilet paper P hold | maintained in the stop state among the product rows on 4 rows conveyor 2a, 2b, 2c, 2d adjoins between the speed-increasing conveyors 14 and 14 10 is held. As a result, when the toilet paper P in a specific row in a stopped state is restarted by the control conveyor 10 and conveyed, it is quickly nipped by the speed-increasing conveyor 14 and transferred at a high speed, and separated from the subsequent toilet paper P.
Further, in the reduction path 5, each partition 15 on the downstream side of each carry-out path 4a, 4b, 4c, 4d is curved or bent inward, and further, a partition on the front side of each adjacent carry-out path 4a, 4b, 4c, 4d. For example, three guides 17 are disposed between 15 and 15 so that the distance between the guides 17 becomes narrower toward the downstream side, and are supported so as to be swingable with the central portion in the longitudinal direction as a fulcrum. Therefore, in the second transport unit 7, the three rows of toilet paper P supplied to any three of the four carry-out paths 4 a, 4 b, 4 c, and 4 d are guided by the guide 17, and the reduced-line carry-out path 6 And are aligned in close proximity to each other.

Further, a shift drive mechanism 16 that drives the control conveyor 10 and the speed-increasing conveyor 14 in each row at different speeds is provided between the first transport unit 3 and the second transport unit 7. In this speed change drive mechanism 16, a large-diameter pulley 18 and a small-diameter pulley 19 are wound by an endless belt 20, and are interlocked by a motor M2 as a drive source.
The motor M2 is coaxially connected so that the shaft portion 21 connected coaxially with the output shaft rotates the drive wheel 22 and the large-diameter pulley 18 of each control conveyor 10 together. The small-diameter pulley 19 is coaxially connected to the drive wheel 23 of each speed increasing conveyor 14.
Therefore, the control conveyor 10 and the speed-increasing conveyor 14 are interlocked with each other by the rotation of the motor M2, and the feed speed of the speed-up conveyor 14 is made higher than the feed speed of the control conveyor 10.

And a pair of surrounding means 25 and 25 are arrange | positioned in the front-back direction on both sides of the 2nd conveyance part 7. FIG. Each circulating means 25 is composed of a pair of pulleys 26a and 26b and an endless belt 27 wound around them. A pusher rod 28 as a pusher member is connected to the belts 27, 27 of the pair of circulating means 25, 25 so as to make a circular motion. One pusher rod 28 is connected because the toilet paper P is one stage.
Note that two sets of toilet paper P may be connected at equal intervals, for example, two at intervals of 180 °, for example, three at intervals of 120 °, for example. Alternatively, a single pusher rod 28 may be provided, and when the toilet paper P has two stages, it may be synchronously fed by two rotations (720 °) and three rotations (960 degrees) in the case of three stages. Further, one rotation of the circulating means 25 is made to correspond to the conveyance of one set of toilet paper P group. However, a plurality of pusher lots 28 are provided in the rotating means 25 at a predetermined interval, and two or three sets of the rotating means 25 are rotated by one rotation. You may make it respond | correspond so that a group of toilet paper P groups may be sent out sequentially.
In the circular motion, the pusher rod 28 is rotated upward from the space S between the first and second transport units 3 and 7 via the pulley 26a on the rear side in the toilet paper feed direction, so that the second transport unit 7 The three rows of toilet paper P delivered to any three carry-out paths 4 are simultaneously pushed forward. And it rotates below through the cutting space 7a of the 2nd conveyance part 7 shown in FIG. 2 via the pulley 26b of the feed direction front side.

The rotating means 25 rotates the pusher rod 28 at a predetermined speed by using the motor M1 connected to one pulley 26b as a driving source, and the pusher rod 28 passes through the space S and the cutting space 7a and rotates in an elliptical locus. To do. The encoder 30 is connected to the motor M1, and the angle θa of the pusher rod 28 at the timing when the detection sensor 13 detects the front end of the row of toilet paper P with 360 ° of the circumference of the pusher rod 28 is measured.
The preset reference angle of the pusher rod 28 at this time is θ0, and the speed of the control conveyor 10 is adjusted according to the difference from the actual measurement value θa, so that the pusher rod 28 reaches the space S at the time. An error or interference with the position of the toilet paper P is eliminated.

When stopping the toilet paper P, the speed of the control conveyor 10 is corrected to increase or decrease so that the front end of the toilet paper P stops at a predetermined position (angle θs) close to the speed increasing conveyor 14 (referred to as correction during stop deceleration). The stopped toilet paper P does not interfere with the circular motion of the pusher rod 28.
When the toilet paper P is continuously conveyed, the pusher rod 28 enters the space S and pushes the rear end of the toilet paper P after the row of toilet paper P is transferred to the carry-out path 4. Thus, the speed of the control conveyor 10 is corrected to increase or decrease (referred to as correction during continuous supply). In this case, the speed increase / decrease correction of the control conveyor 10 differs depending on the number of toilet papers P (rows) in a row.
As described above, when the toilet paper P is detected by the detection sensor 13, the rotation angle measured value θa of the pusher rod 28 and the difference between the preset reference angle θ0 (θ0−θa), the number of toilet paper P in a row, and each control conveyor The speed of each motor M2 is adjusted by the control device 32 so that the speed of each pair of control conveyors 10 is corrected and controlled in relation to 10 continuous running speeds or stop positions.

Next, the control conveyor 10 for transporting the toilet paper P, the speed increasing conveyor 14, and the control device 32 for the pusher rod 28 will be described with reference to FIG.
In the control device 32, an input means 34 and a storage means 35 are connected to a control calculation means (CPU) 33. The input means 34 includes the type of product to be transported, such as the toilet paper P, the size thereof, the number of transported columns, the number of columns to be transported, the number of rows, that is, the number of products in one row, the number of stacked stages at the time of packaging, the rotational speed of the pusher rod 28, A product push-out timing and the like in the second transport unit 7 are set and input, respectively.

Moreover, the control calculating means 33 is provided with the following control function for every conveyor 2a, 2b, 2c, 2d of the 4th 1st conveyance part 3, for example.
That is, each conveyor 2a to 2d (1st to 4th rows) includes a pool sensor 11, a timer T2, a lower limit sensor 12, a timer T1, and a sensing sensor 13, and further drives and stops each pair of control conveyors 10, 10. A motor M2 is provided.
Also, in each of the conveyors 2a to 2d, the driving speed of each motor M2 is determined based on the difference between the measurement angle θa of the pusher rod 28 by the encoder 30 synchronized with the detection of the tip position of the toilet paper P by the detection sensor 13 and the reference angle θ0. That is, the stop signal to the control conveyor 10 having the synchronous operation means 36 for correcting and controlling the speed of each control conveyor 10 (referred to as correction during continuous supply) and the toilet paper P in the transport state of one conveyor 2 of the first transport unit 3. Driving stop means for stopping the toilet paper P row at a predetermined position by decelerating and correcting the driving speed of the motor M2, that is, the speed of the control conveyor 10 (referred to as correction during stop deceleration) in response to the output of the sensor and the position detection signal from the sensor 13. 38 is connected to the control calculation means 33.
Further, in response to signals from the pool sensor 11 and the timer 11a, the lower limit sensor 12 and the timer 12a, the start signal indicating whether or not each conveyor 2 in the first transport unit 3 can transport the next toilet paper P is output. An activation permission confirmation unit 37 is connected to the control calculation unit 33. Moreover, the control calculation means 33 is connected to the motor M2 of the control conveyor 10 and detects whether or not the motor M2 is actually driven.

Further, the control calculation means 33 performs a process of transferring the toilet paper P to the second transport unit 7 by the control conveyors 10 and 10 when the toilet paper P is in the middle of operation when the reduced-column product supply device 1 is OFF. A drive control means 39 is connected to terminate the operation after the termination.
Further, regarding the toilet paper P in the four rows of conveyors 2 a to 2 d in the first transport unit 3, a stop is made to determine whether to stop driving the toilet paper P in any one of the conveyors 2 and output a stop row signal to the control calculation means 33. A column determining unit 41 and an activation column determining unit 42 for outputting an activation column signal for activating the toilet paper P in the conveyor 2 in a different stopped state to the control arithmetic unit 33 are provided.
The stop train determination means 41 confirms whether or not the conveyor 2 stopped last time is actually moving and outputs a signal for stopping another conveyor 2 to be stopped next time.
When the activation sequence determination unit 42 confirms the activation signal for the control conveyor 10 for another conveyor 2 to be activated from the stopped state by the activation availability confirmation unit 37, the one for the conveyor 2 stored in the storage unit 35 is stored. The control conveyor 10 is selected to be stopped and rewritten. When the activation signal cannot be confirmed by the activation availability confirmation means 37, the information in the storage means 35 is maintained as it is as the control conveyor 10 that should stop the control conveyor 10 for the other conveyor 2 in the stopped state.
Thereby, in these two judgment means 41 and 42, regarding the four rows of conveyors 2a to 2d, the control conveyor 10 of the toilet paper P to be stopped from the conveyance state and the control conveyor 10 of the toilet paper P to be started from the stop state Are controlled so as to be sequentially changed for each transport of a set of toilet paper P groups.
When the activation signal of the control conveyor 10 to be activated cannot be confirmed, the control conveyor 10 of another conveyor 2 in the stopped state is set as the control conveyor 10 to be stopped as it is, and the control conveyor of one conveyor 2 scheduled to be stopped next time 10 is maintained in the driving state without stopping.

The reduced-column-type product supply device 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next.
Description will be made along the timing charts of FIGS. 4 to 6 and the flowcharts of FIGS. FIG. 7 is a main flowchart, and FIGS. 8 to 11 are subroutine charts.
First, toilet paper P sequentially manufactured by a manufacturing apparatus for toilet paper P (not shown) is cut, for example, every predetermined length and supplied to the reduced-column product supply device 1. In the reduced column type product supply device 1, a plurality of toilet paper P groups are sequentially distributed to, for example, four rows of conveyors 2a to 2d provided in the first transport unit 3, and the conveyors 2a to 2d are always driven by a motor M3 to be The toilet paper P groups in a row are conveyed in the direction of the downstream control conveyor 10 in a state where they are in contact with each other.
Here, as shown in the main flow of FIG. 7, various input values such as the product type, the number of conveyance columns, the number of rows, the number of steps, the number of column reductions are set in advance from the input unit 34 of the column reduction type product supply apparatus 1. (Step 101). In the first embodiment, a set of toilet paper P to be packaged is 1 column 3 rows (3) × 3 columns × 1 stage.

Next, regarding the toilet paper P that is continuously transported from the first transport unit 3 to the second transport unit 7 without stopping, depending on the length of the toilet paper P alone, the number of rows in one column, etc. Based on the difference between the measurement angle θa of the pusher rod 28 in the rotating means 25 when the detection sensor 13 detects P and the reference angle θ0 set in advance, all the toilet paper P in one row is pushed by the pusher rod 28 to the second transport unit 7. The speed of each control conveyor 10 is corrected by, for example, one set or one stage of toilet paper P to be packaged by the synchronous operation means 36 so that it can be pushed by each of the carry-out paths 4a to 4d. (Correction during continuous supply).
Further, when the toilet paper P in one row of the conveyor 2 to be stopped by the first transport unit 3 is decelerated and stopped by the control conveyor 10, in the circulation means 25 when the toilet paper P at the tip of the row is detected by the sensor 13. Based on the difference between the angle θa of the pusher rod 28 and the theoretical angle θx, the control conveyor 10 is decelerated by the drive stop means 38 so that the toilet paper P corresponds to a predetermined position in the space S, that is, the stop angle θs of the pusher rod 28. Stop at a predetermined position (refer to FIG. 12: correction during stop deceleration). This stop position is a non-contact position where the first toilet paper P enters between the C-shaped speed increasing conveyors 14 and 14.

Stop deceleration correction will be described with reference to FIG. The horizontal axis in FIG. 12 indicates the position of the detection sensor 13 from the time when the tip of the toilet paper P is at the position of the shaft portion 21 of the drive wheel 22 of the control conveyor 10 (the rotation angle of the pusher rod 28 at this time is 0 °). The distance from the pusher rod 28 to the stop position of the toilet paper P (stop angle θs of the pusher rod 28) via the theoretical angle θx of the pusher rod 28 at the timing when the tip of the toilet paper P is detected by the detection sensor 13 is determined. This is indicated by the change in angle. The vertical axis indicates the speed of the control conveyor 10.
On the horizontal axis, the distance from the shaft portion 21 (angle 0 ° of the pusher rod 28) to the stop position (also the angle θs) is L1, and from the shaft portion 21 (angle 0 °) to the sensing sensor 13 (angle θx). Is L2, the distance from the sensing sensor 13 to the stop position is (L1-L2). In FIG. 12, L1 and L2 are represented by areas.
The angle from the sensing sensor 13 to the stop position is θs−θx. for that reason,
θs−θx: θs = √ (L1-L2): √ (L1)
It becomes.
Therefore, θx = θs {1−√ (L1−L2) ÷ √ (L1)}
It becomes.

Therefore, when the measurement angle of the pusher rod 28 measured by the encoder 30 corresponding to detecting the toilet paper P decelerating for stopping by the detection sensor 13 is θa and the theoretical angle is θx, the angles θx and θa From this difference, the deceleration speed of the control conveyors 10 and 10 is corrected by the drive stop means 38 so that the toilet paper P stops at the stop angle θs (the speed change is indicated by a one-dot chain line or two-dot chain line in FIG. 12). Good. This is correction during stop deceleration of the control conveyor 10.
Based on these correction calculations (step 102), by performing correction during continuous supply and correction during stop deceleration, the three rows of control conveyors 10 in the first transport unit 3 are moved continuously, and the other row is controlled. The conveyor 10 is decelerated and stopped. The control conveyor 10 of the conveyor 2 to be stopped and the control conveyor 10 of the conveyor 2 to be started are set in advance, and each time a set is packed from the stop row determination unit 41 and the start row determination unit 42, the stop row signal and the start row The signal is output to the control calculation means 33 as a signal.
Thus, after each of the three rows of toilet paper P that have been reduced passes through the space S without interfering with the pusher rod 28 that continuously moves around, it is transferred from the first transfer unit 3 to the second transfer unit 7. The pusher rod 28 can be pushed.
On the other hand, the toilet paper P of the conveyor 2 that is stopped in a reduced row is stopped from the control conveyor 10 at a predetermined position in the space S without interfering with the rotating pusher rod 28, and the vicinity between the pair of speed increasing conveyors 14 and 14 is stopped. Held without contact. As a result, when restarted, it can catch up with the other two rows of toilet papers P that run continuously and can run synchronously.

Under such a control state, when the toilet paper P is sequentially supplied to the respective conveyors 2a to 2d of the first transport unit 3 of the reduced-type product supply device 1 in which the control conveyor 10 is stopped, the respective conveyors 2a to 2d are Since the control conveyor 10 that is always driven and is located in front of the conveyor 2 is stopped or driven at a lower speed than the conveyors 2a to 2d, the toilet papers P on the conveyors 2a to 2d are in a linear close contact state in which the end surfaces are in contact with each other. The moving pressure is applied to the downstream side.
Then, in step 103 (startability determination flow), it is determined whether or not the reduced-column product supply device 1 can be started. That is, in each of the conveyors 2a to 2d, when the toilet paper P is detected by the lower limit sensor 12 and the pool sensor 11, and the detection state is maintained for a predetermined time T1 and T2 by the timers 12a and 11a, the control conveyor 10 Is activated and the activation signal is turned on (see FIG. 4). Then, in the operation request flow of the control conveyor 10 in step 104, the operation request signal of each control conveyor 10 is maintained in the ON state.

Then, the activation line determination means 42 determines the line to be activated next time by detecting the activation signal relating to each control conveyor 10 of each conveyor 2 (step 105). Further, the stop train determination means 41 receives the output of the signal from the motor M2 of the control conveyor 10 that was stopped last time, and determines whether the control conveyor 10 of the remaining conveyor 2 is stopped (step 106). Based on these signals, the pair of control conveyors 10 and 10 of each conveyor 2 is activated and stopped (step 107).
In steps 105 to 107, the activation signal of the control conveyor 10 in the stopped state in the conveyor 2 to be activated next is determined by the activation availability confirmation means 37 (activation determination), and if it can be activated, it is activated by the motor M2. Further, it is determined by the stop train determination means 41 whether the control conveyor 10 of the conveyor 2 to be stopped next should be stopped (stop determination), and is decelerated and stopped by the motor M2.
Thus, the start and stop determinations are made before and after, and the control conveyors 10 and 10 for two rows that are continuously operated and the control conveyors 10 and 10 for the other two rows that are started and stopped are sequentially switched. This switching means is defined as a virtual clutch.
In the present embodiment, as shown in FIG. 5, the control conveyor 10 first activates and transports the toilet paper P rows of the conveyors 2a to 2c in the first set, and stops the toilet paper P row of the conveyor 2d. . In the next round, the toilet paper P row of the conveyor 2d is activated to synchronize with the conveying state of the conveyors 2b and 2c, and the toilet paper P of the conveyor 2a is stopped. In this way, starting and stopping of the control conveyor 10 in each conveyor 2 are sequentially switched. And the toilet paper P of each conveyor 2a-2d is each conveyed by each control conveyor 10, maintaining the reduced state which consists of 3 rows.

The main flow is performed in this way. Next, main operations of the main flow will be described along the subroutines shown in FIGS.
First, the activation permission determination flow in step 103 will be described with reference to the flowchart of FIG. For the conveyors 2a to 2d in each operating state, the lower limit sensors 12 below detect the toilet paper P and turn on (step 201). In this state, the timer 12a is activated and a predetermined time T1 elapses (step 202). . In this case, if each conveyor 2a-2d is an operation state, it will confirm that each toilet paper P is supplied continuously in either a conveyance state or a stop state.
Next, the toilet paper P on each of the conveyors 2a to 2d is detected by the rear pool sensor 11 and turned on (step 203). In this state, the timer 11a is activated and a predetermined time T2 elapses (step 204). Also in this case, if each conveyor 2a-2d is an operation state, it will confirm that each toilet paper P is supplied continuously in either a conveyance state or a stop state.

As shown in FIGS. 4 and 5, when both the sensors 12 and 11 are in the ON state and the times T1 and T2 have elapsed (step 205), the activation signal of the control conveyor 10 is turned on (step 206). Thereby, each pair of control conveyors 10 and 10 in the conveyors 2a to 2d determines that the toilet paper P in each row can be transported.
After that, when the lower limit sensor 12 is turned off, it is determined that the toilet paper P is not being conveyed and the activation signal is turned off (step 208). And the control conveyor 10 of the row | line | column determines that it is a conveyance impossible state.

Next, the start determination of the control conveyor 10 will be described along the start / stop determination and instructions shown in FIGS.
First, in the activation determination flow shown in FIG. 9, after each activation signal ON in the timing chart of FIG. 6 and the flow of FIG. 8 is output, whether the operation request of the control conveyor 10 in the four conveyors 2a to 2d is in the ON state. It is confirmed whether or not the supply device 32 (including all of the plurality of conveyors 2) is at the start determination timing (step 301).
In the case of NO, there is no need to start up, so the process returns to the main flow. In the case of YES, when the virtual clutch connection request OFF is issued for all the control conveyors 10 in the conveyors 2a to 2d in all rows (step 302), the virtual clutch connections in the row that is initially activated as the start of operation. The request is turned ON (step 303), and the toilet paper P to be reduced can be activated, and an initial stop row flag is set (step 311). On the other hand, when the virtual clutch connection request OFF has not been issued (step 302), the supply device 32 is in a switchable state for the toilet paper P to be reduced during operation.

If the clutch connection request OFF of all rows is not issued in step 302, it is determined whether the remaining conveyor 2 that should be in a stopped state (conveyor 2d in this embodiment) has already been started or stopped (step 304). . If it has been activated, it is determined that there is an abnormality because it is in the four-row transport state based on the signal from the motor M2 (step 305), and all four rows of virtual clutch connection requests are turned off and the process is terminated (step 306).
Here, when the control device 32 is activated, the control conveyors 10 and 10 of the conveyors 2a, 2b and 2c are operated as shown in FIG.
In the speed change drive mechanism 16, the speed-increasing conveyors 14 and 14 are operated at a higher speed in conjunction with the operation of the control conveyors 10 and 10 using the motor M2 as a drive source, and the toilet paper P of each conveyor 2a, 2b and 2c is operated. The row is transferred to the carry-out paths 4a, 4b, and 4c of the second transfer unit 7. The toilet paper P speeded up by the speed-increasing conveyor 14 is separated from the subsequent set of toilet paper P in the space S.
When the leading toilet paper P protrudes into the space S, the detection sensor 13 detects this, and according to this, the encoder 30 detects the angle θa of the pusher rod 28 of each circulating means 25. When the angle θa is different from the theoretical angle θx, the speed of each control conveyor 10 is corrected during the continuous supply by the synchronous operation means 36, and the row of toilet paper P of each conveyor 2a, 2b, 2c becomes the carry-out path 4a, 4b. After being transferred to 4c, the pusher rod 28 floats from the space S and goes around, and pushes its rear end.

In step 304, if the toilet paper P row of the conveyor 2 (2d) is in a stopped state, it is determined whether or not the control conveyors 10 and 10 can be activated (step 307). When the activation signal is detected, the virtual clutch connection request is turned ON (step 308), the stopped conveyor 2 (2d) is activated, and the column to be stopped next time is changed (step 309).
Further, as shown in FIGS. 5 and 6, the next set of toilet paper P of the control conveyors 10 and 10 of the conveyor 2d to be activated is earlier than the next set of toilet paper P of the control conveyor 10 that is continuously driven. Start activation on the control conveyor 10.

If the activation signal ON from the activation line availability confirmation means 37 cannot be detected in step 307, the conveyor 2 (2d) in the stopped state cannot be activated, so the three conveyors 2a and 2b currently in the conveying state cannot be activated. 2c is continued and it is judged whether it can convey with the control conveyor 10, ... (step 310). When the control conveyors 10 of the three conveyors 2a, 2b, and 2c are in the continuous conveyance NO, it is abnormal, so that all the control conveyors 10 are turned off (step 306), and each control of the three conveyors 2a, 2b, and 2c is controlled. If the conveyor 10 is capable of continuous conveyance (YES), the process continues and the toilet paper P of these conveyors 2a, 2b, 2c is transferred to the unloading path 4a. 4b. Transfer to 4c.
As a result, even if the control conveyor 10, the speed change drive mechanism 16, the conveyor 2 or the like in one row out of the four rows has a defect, the reduced row conveyance can be performed reliably (see FIG. 6).
In this way, the conveyors 2a to 2d to be stopped and the conveyors 2a to 2d to be started from the stopped state can be sequentially transferred while being switched by the virtual clutch.

Next, a stop determination flow of the control conveyor 10 will be described with reference to FIGS.
First, as in step 301, it is determined whether or not an operation request ON has been output for the control conveyors 10 and 10 in each of the conveyors 2a to 2d (step 401). In the case of NO, there is no need to drive the control conveyor 10. Therefore, all virtual clutch connections are turned off (step 402). If an operation request is made at step 401 (YES), a timing check is performed (step 403) to determine whether or not it is time to determine stop (step 404). Return to the main flow (step 107).

In step 404, when it is the timing of stop determination (YES), it is determined whether or not the control conveyor 10 to be stopped (control conveyors 10 and 10 of the conveyor 2a in this embodiment) is already stopped (step 405). If already stopped (YES), the process returns to the main flow. If it is not stopped (NO), that is, if it is in the transport state, it is confirmed based on the signal from the motor M2 that the control conveyors 10 and 10 of the conveyor 2 (conveyor 2d) stopped last time are in the activated state ( (YES) (Step 406) The virtual flag connection request is turned OFF to stop the control conveyors 10 and 10 of the conveyor 2a (Step 407) (see FIG. 6), and the drive stop means 38 corrects the deceleration for stopping.
Here, the control conveyor 10 of the conveyor 2a to be stopped detects the leading end of the toilet paper P with the sensor 13, measures the angle θa of the pusher rod 28, and stops and decelerates the control conveyors 10 and 10 with the drive stop means 38. Medium correction is performed, and the front end of the first toilet paper P is stopped at a predetermined position where it does not interfere with the pusher rod 28 in the vicinity between the speed increasing conveyors 14 and 14. The row of toilet paper P to be stopped advances forward from the time when the stop signal is generated by the stop after the deceleration correction, and stops at an accurate stop position. Therefore, when the next start-up is performed, the toilet paper of the other two rows of conveyors 2b and 2c is not required to increase in acceleration speed (and is started at a timing earlier than the other two rows of toilet paper rows of the conveyors 2b and 2c). It can catch up to the par line early and can carry it at a constant speed. Thereby, the slip of the control conveyor 10 at the time of starting acceleration can be prevented.
If it is determined in step 406 that the control conveyor 10 of the conveyor 2d is not in the activated state (NO), it is determined that the control conveyor 10 of the conveyor 2d is activated in the activation determination flow of FIG. It judges (step 408), controls the virtual clutch connection request OFF of all the conveyors 2a-2d (step 402), and stops the control conveyor 10. FIG.

In addition, when the operation is turned off during the operation of the reduced-column product supply device 1, the toilet paper P in each row is packaged as one set of 2 rows, 1 row, 3 rows, 1 row, 3 rows, 2 rows, etc. In this case, a control conveyor operation request flow for discriminating one of these and outputting an operation request for the control conveyor 10 until the processing is completed to end the operation will be described with reference to FIG.
When the operation of the reduced-column product supply device 1 is turned off, it is first determined whether or not there is an operation request for the next process, here, the packaging process (step 501). If there is an operation request (YES), it is determined whether or not the control conveyors 10 of all rows are already stopped (step 502). If all the rows are stopped, the operation request for the control conveyors 10 in all rows is output (ON) at the start of operation (step 503), and the process returns to the main flow (step 105). If the control conveyors 10 in all rows are not in a stopped state in step 502 (NO), it is determined that the supply device 1 is in operation and the process returns to the main flow (step 105).

On the other hand, if an operation request for the next process is not issued in step 501 (NO), it is determined whether or not there is an operation request for the control conveyors 10 in all rows (step 504). Returning to the main flow, if the operation request is ON, it is determined whether or not the two-row operation of each of the control conveyors 10 and 10 of the four-row conveyors 2a to 2d is performed (step 505). In the case of YES, it is determined as a set of two rows of toilet paper P, and in the case of NO, it is determined as a set of three rows of toilet paper P.
Next, it is determined whether or not one row is packaged as a set for two rows (step 506), and in the case of two rows and one row, an operation request OFF of the control conveyor 10 is output (step 507). The control conveyor 10 is finished without performing the next operation.

Further, if NO is determined in step 506, they are packaged as a set in two rows and two stages, so in the next step 508, the pusher rod 28 of the circulating means 25 is rotated by the encoder 30 by a reference angle (for example, one rotation). It is determined whether or not the angle exceeds 180 °. When it is determined that one set of toilet paper P has two stages, two pusher rods 28 are attached to the belt 27 of the circulating means 25 at intervals of 180 °. Therefore, if the rotation of the belt 27 synchronized with the rotation of the control conveyor 10 exceeds 180 ° from the reference angle, it is determined that the second pusher rod 28 has already pushed the second row of toilet paper P, The operation request of the control conveyor 10,... Is turned off (step 507).
In step 505, if the two-row operation is not being performed (NO), the three-row operation is recognized as described above. Next, it is determined whether or not three rows and one stage are packaged as one set (step 509). In the case of three rows and one stage, it is determined whether or not the start determination timing has been exceeded (step 510). If yes (YES), the operation request of the control conveyors 10 and 10 is turned off (step 511).

Further, when it is determined in step 509 that the operation is not the three-row / first-stage operation, the third-row / two-stage operation is recognized. Then, it is determined whether or not the chain conveyors 28, 28 provided on the belt 27 of the circulating means 25 at 180 ° intervals exceed the reference angle (angle 0 °) by 180 ° (step 512). If it is determined that the angle exceeds 180 °, it is determined that the second-stage three-row toilet paper P has been pushed out, and the control conveyor 10 and the 10 operation request OFF are ended (step 513). When it is determined that the angle does not exceed 180 °, the control conveyors 10 and 10 are kept in the operation request ON state in order to push out the second-stage three-row toilet paper P, and the process returns to the main flow (step 105).
When the operation request is OFF, the clutch connection request for all rows is turned OFF in the stop determination routine, and each control conveyor 10 is stopped.

FIG. 13 shows a timing chart when the toilet paper P is packaged as one set in three rows and two stages. In the figure, when the control device 32 is activated, the toilet paper P of the conveyors 2a, 2b, and 2c is conveyed in three rows. When the first three rows are transferred to the second transport unit 7, the toilet paper P of the conveyor 2a is decelerated and stopped by the control conveyors 10 and 10 after confirming the activation of the toilet paper P of the conveyor 2d. Therefore, the toilet paper P in the second row and the third row is conveyed by the conveyors 2b, 2c, and 2d, and is transferred to the carry-out paths 4b, 4c, and 4d of the second conveyance unit 7.
Next, the control conveyor 10 of the conveyor 2a in the stopped state is activated, and the activation is confirmed, and the control conveyor of the conveyor 2b is decelerated and stopped. When the activation of the control conveyors 10 and 10 of the conveyor 2a is confirmed, if the signal from the motor M2 of the conveyor 2a cannot be confirmed, it is determined as abnormal and the control conveyors 10 of all the conveyors 2 are stopped.
Such operations are sequentially repeated to carry out the reduced transport of the toilet paper P in a set of 3 rows and 2 stages, and packaging is performed in the next process.

As described above, according to the present embodiment, when a plurality of toilet papers P are transported in a reduced row, the toilet paper trains that are continuously transported without being stopped and are started from a stopped state Since the toilet paper rows that are to be stopped are sequentially replaced and supplied, it is not necessary to stop the toilet paper P in all rows, and the toilet paper rows that are activated are started earlier than the toilet paper rows that are continuously conveyed. Therefore, since it is possible to follow and perform synchronous conveyance, the conveyance speed can be increased and efficient line-reduction conveyance can be performed.
In addition, prior to starting deceleration for stopping the line to be reduced and stopped for the toilet paper line, check whether or not the stopped line can be activated, and if the activation signal cannot be confirmed, the line is stopped. Since the continuous conveyance is performed without decelerating and stopping the row, the reduced row conveyance of the required row can be reliably performed.
In addition, when the vehicle is stopped prior to the start-up acceleration, the toilet paper train is gradually decelerated to the pusher rod 28 in the vicinity of the speed increasing conveyors 14 and 14 in the second transport unit 7 protruding from the control conveyors 10 and 10 in the first transport unit 3. Since it can be held at a position where it does not interfere and the stop position is set in the vicinity of the speed-up conveyors 14 and 14 by decelerating conveyance, it quickly catches up with other continuous conveyance toilet paper rows without rapid acceleration at the next start-up acceleration, and is synchronously conveyed It can be smoothly supplied to the next process, and no slippage occurs in the toilet paper line during acceleration.

Further, the first transport unit 3 can smoothly adjust the two toilet paper rows to be stopped and started for the reduced column replacement by the start-up row determination unit 42 and the stop-row determination unit 41, and the second transport unit 7 can push the pusher rod 28. By pressing a plurality of toilet paper rows at the same time, the length and supply speed of the plurality of toilet paper rows to be supplied to the next process do not vary and stable supply can be performed.
By measuring the angle θa of the pusher rod 28 in the circulating means 25 in synchronization with detection of the front end of the toilet paper row by the detection sensor 13, it is possible to perform correction during stop deceleration of the control conveyors 10 and 10 and correction during continuous supply. In addition, the continuous conveyance speed and stop position of the toilet paper line can be controlled with high accuracy.
Further, the pool sensor 11 and its timer 11a, the lower limit sensor 12 and its timer 12a determine whether or not continuous conveyance or activation can be performed while confirming the subsequent toilet paper row, so that continuous supply to the next process can be performed with high accuracy.

  Further, in the embodiment, toilet paper P composed of a set of one or more stages in a plurality of rows is adopted as an article to be packaged, but the number of rows, the number of stages, and the number of toilet paper in one set are arbitrary. Although toilet paper P is used as an article to be packaged, other various roll-like articles and other arbitrary articles can be employed.
