[0014]

[Operation] The carry-out conveyor carries the take-up roll to the machine side,
The machine-side conveyor receives the take-up roll from the carry-out conveyor, passes it to the above-mentioned transfer conveyor, and conveys it downstream by the transfer conveyor, so that the operator does not have to load and unload the take-up roll, and together with the take-up roll. There is no need to move. In addition, the transport path can be evacuated from the installation space of the winding roll processing equipment in the center of the building.

When the loading platform is conveyed to the take-up roll receiving position by the unloading conveyor, the work of individually carrying the loading platform to each winding roll receiving position on the unloading conveyor becomes unnecessary.

[0016]

EXAMPLE 1 Example 1 of the present invention will be described with reference to FIGS. 1 is a schematic plan view of the first embodiment, and FIG. 2 is a schematic side view of a sheet dividing and winding machine. The winding roll R is formed by dividing the strip-shaped sheet 2 into a plurality of strips by the slitter 3 in the sheet dividing and winding machine 1 and alternately allocating the strips to the front and rear winding positions, and winding the roll at the tip of the winding arm 4. Made Then, each winding roll R that has been wound up is removed from the winding arm 4, and is a device such as a weighing device or a packaging device (not shown) located downstream of the sheet dividing and winding machine 1 by the winding roll conveying device of the present invention. Be transported to.

The take-up roll conveying device is a sheet dividing winder 1
Along with the winding positions before and after the conveyor roll 5, the conveyor 5 extends in parallel with the width direction of the winding roll R, that is, the central axis direction, and the conveyor 5 is provided in series on the machine side of the sheet dividing and winding machine 1. The machine-side conveyor 6 and the transfer conveyor 7 extending in the crossing direction of the machine-side conveyor 6 are provided.

The carry-out conveyor 5 receives the wound-up take-up rolls R from the respective take-up arms 4 all at once on a loading platform P placed on the carry-out conveyor 5, and carries the received take-up rolls R in the width direction thereof. It can be carried out to the machine side of the sheet split winding machine 1.

The machine-side conveyor 6 can receive the take-up roll from the unloading conveyor 5 in a state where it is placed on the loading platform P, and deliver it to the transport conveyor 7 in that state. In this embodiment, the machine-side conveyor 6 is composed of an intermediate conveyor 8 adjacent to the carry-out conveyor 5 and an intersecting conveyor 9 intersecting with the transfer conveyor 7. The carry-out conveyor 5, the intermediate conveyor 8 and the cross conveyor 9 are belt conveyors,
The transport conveyor 7 is a chain conveyor. Further, the carry-out conveyor 5, the cross conveyor 9 and the intermediate conveyor 8 are
In order to carry an empty cargo bed P to the take-up roll receiving position, it is possible to carry it in the opposite direction.

At the intersection with the conveyor 7, the cross conveyor 9 is a conveyor endless belt 1 as shown in FIG.
0 is avoided below the endless chain 11 of the conveyor 7. Further, the take-up roll R placed on the loading platform P may be lowered onto the conveyor 7 and handed over.
It is supported on the elevating mechanism 12 so that it can lift and receive the upper platform P, and can be moved up and down by being driven by the elevating drive device 13.

The sheet dividing and winding machine 1 shown in FIG. 1 divides the strip-shaped sheet 3 into four product sheets and four winding rolls R are provided.
However, the sheet dividing and winding machine 1 can variously change the division number and the division width of the strip-shaped sheet. Therefore, a large number of winding rolls can be obtained by one winding operation, and the width of the winding roll can be variously changed.

When the take-up rolls having various widths are placed on the individual carriers and conveyed by the conveyor, the stability of the take-up roll during the conveyance is maintained and the space occupied for the conveyance is not increased. It is desirable to prepare several types of bed P having a length corresponding to the width of the winding roll. However, doing so complicates the handling such as preparation, storage, and recovery of the loading platform P, and thus requires a lot of one type of loading platform P in this embodiment. That is, the sizes of the cargo beds P are substantially the same, and the respective cargo beds P have compatibility with each other. Then, the winding rolls R are placed on the number of loading platforms P corresponding to the width and conveyed. That is, if the width of the take-up roll R is below a certain value, it is supported by one loading platform P, and if it exceeds a certain value, it is supported by two loading platforms P.

As shown in FIG. 2, the loading platform P has a concave portion on its upper surface for preventing the winding roll placed thereon from rolling down. In order to prevent the take-up rolls placed on the loading platform P from falling down, protrusions may be provided on both edges of the loading platform instead of the recesses, or the rollers may be placed on rollers arranged in parallel. Further, in order to convey the information about each winding roll R together with each winding roll R to each loading platform P, and to save the trouble of handling the information, data is written in the center of the lower surface of the loading platform P in a non-contact manner. A commercially available readable data carrier M is attached. If the data carrier M is provided at the center of the lower surface of the luggage carrier P, the handling of the luggage carrier P does not become complicated because there is no problem even if the front and rear of the luggage carrier P are interchanged. When the change range of the width of the take-up roll is wider, one take-up roll may be supported by three or more beds P.

Further, in the sheet dividing winder, a large number of take-up rolls can be wound up at one time, but even if they are supplied to the next processing equipment all at once, they are stored near the processing equipment in order to wait for the processing. Need to be kept. Therefore, in FIG. 1, the conveyor 7 conveys the take-up roll R received from the machine-side conveyor 6 in the radial direction thereof, that is, in the direction intersecting the central axis of the take-up roll R. Since the radius of the take-up roll R is generally smaller than the width of the take-up roll and does not change so much, a large number of take-up rolls R can be placed on the conveyor 7 even in a short conveying path.

Further, the transport conveyor 7 is provided with a four-end transport endless chain 11 for transport, which is circulated and driven during transport, so that no problem occurs even if the number of the load platforms P supporting the winding roll R changes. Are provided in parallel at intervals shorter than the length. Then, when the width of the winding roll is small, one loading platform P on which the winding roll R is mounted is supported by the two endless chains 11 on the inner side, and when the width of the winding roll is large, two loading rolls R are mounted. The platform P is supported by a pair of endless chains 11 on both sides.

When all of the take-up rolls R wound up by the sheet dividing and winding machine 1 are unloaded onto the loading platform P, the carry-out conveyor 5 conveys the winding roll R together with the loading platform P to the machine side conveyor 6 one after another. Send out. At this time, in the machine-side conveyor 6, the intermediate conveyor 8 is driven and driven in the same direction and at the same speed as the unloading conveyor 5 in order to smoothly receive the winding roll R. When the intermediate conveyor 8 receives the take-up roll R and conveys the take-up roll R by the width of the take-up roll and a necessary distance from the next take-up roll R, the conveyance is stopped, and the take-up roll R and the next take-up roll R are stopped. When the distance from the take-up roll R reaches a required distance, the conveyance is restarted. Then, the transporting drive is repeated intermittently in this way to reduce the mutual interval between the received winding rolls R.

All the take-up rolls R are the sheet-dividing winder 1
When it is sent out from the unloading conveyor 5, the sheet dividing winder 1 can proceed with the preparation work for starting the next winding operation. On the other hand, the machine-side conveyor 6 sequentially sends the received take-up roll R to the transport conveyor 7 with the take-up roll R placed on the platform P. Information about the winding roll is written in the data carrier M of the loading platform P by the data writing device 14 provided in the intermediate conveyor. The sent-out winding roll R is transferred to the transport conveyor 7 while being placed on the loading platform P, and is transported downstream by the transport conveyor 7.

The loading platform P may be prepared by the operator carrying it to the take-up roll receiving position, but in this embodiment, the loading platform is placed on the unloading conveyor 5 in order to reduce the burden on the operator. Place P and carry it into the take-up roll receiving position.
Further, the loading platform 15 is used to store the loading platform P so that it can be supplied when needed.

FIG. 4 is a schematic side view of the bed feeder.
The loading platform supply device 15 replaces the empty loading platform P returned by the loading platform returning conveyor 16 with the loading platform returning conveyor 16.
And a storage unit 17 for receiving and storing from the storage unit 17
It is provided with a stopper device 18 capable of sending out the loaded beds P stored one by one in a timely manner, and a transport mechanism 19 for carrying the delivered cargo beds P to the transport conveyor 7.

The storage unit 17 is the conveyor 1 in the embodiment of FIG.
7 and is provided below the conveyor 7 to save the installation space. The conveyor 17 comprises an endless chain 20 driven in the direction of arrow A. There are a pair of the endless chains 20 as shown in FIG.
As shown in FIG. 5, a large number of rollers 21 that are capable of slipping and rotating in the transport direction of the conveyor 17 are mounted at a predetermined pitch to support the loading platform P at 0. When the stopper device 18 does not prevent the conveyance of the load platform P, the transport resistance of the load platform P is small, so that the roller 21 does not slip and rotate, and the load platform P moves together with the roller 21. However, when the stopper device 18 blocks the conveyance of the loading platform P, the conveyance resistance increases and the roller 21 slips and rotates. Then, the roller 21 moves with the endless chain 20 while rolling on the lower surface of the stopped loading platform P. Therefore, the loading platform P transferred from the loading platform returning conveyor 16 to the conveyor 17 is moved by the conveyor 17 to the stopper device 1.
8 is sent to the stopper device 18 from the beginning.
Therefore, the conveyance is stopped, and the sheets are stored on the conveyor 17 at close intervals.

As a storage unit, instead of the conveyor 17 shown in FIG. 4, for example, a large number of shafts arranged in parallel,
The free roller and the driving roller are mounted coaxially, and the other roller fixed to the shaft is brought into contact with the drive belt to rotate the shaft, thereby rotating the free roller so that the free roller can slip. It is possible to use a known conveyor, commonly called accumaflow, etc., in which an object to be conveyed is placed and conveyed.

As shown in FIG. 5, the stopper device 18 is provided so that the cargo beds P can be sent out from the storage section 17 one by one, as shown in FIG.
A rod-shaped first stopper 22 that engages with the second loading platform P, a rod-shaped second stopper 23 that engages with the second loading platform P, and an oscillating plate 24 that pushes out the loading platform P and assists the delivery.
The end portion of the first stopper 22 is fixed to the tip of an arm 26 that can swing about the fulcrum shaft 25, and the second stopper 2
The three-end portion is fixed to the tip of an arm 28 that can swing around the fulcrum shaft 27. The swing plate 24 can swing around the shaft 28. A connecting rod 29 between the arm 26 and the arm 28
Because they are connected with each other, they work together. The arm 26 is oscillated by the fluid pressure cylinder 30 and oscillates.
The stopper 22 and the second stopper 23 can be provided at the position shown by the solid line and the position shown by the chain line in FIG. 5, respectively. Therefore, when the first stopper 22 blocks the movement of the leading bed P, the second stopper 23 moves up and does not engage with the second loading bed P, and the first stopper 22 moves up and lifts the leading bed. When P is released, the second stopper 23
Can engage the second carrier P and prevent the second carrier P from being delivered. The rotation of the shaft 25 is not shown on the shaft 28 so that the rocking plate 24 can move from the position shown by the solid line to the position shown by the broken line while the arm 22 swings from the position shown by the solid line to the position shown by the chain line. It is adapted to be transmitted via a transmission device.

When the first stopper 22 is moved up, the top loading platform P is released, pushed by the swing plate 24 swinging to the position shown by the chain line, and sent out by receiving the carrying force of the conveyor 17. When the top loading platform P is sent out, the first
The stopper 22 descends and the second stopper 23 rises. Further, at that time, the rocking plate 24 comes to the position shown by the solid line. Then, the second loading platform P is released and advances with the subsequent loading platform P, reaches the first stopper 22, and is blocked from moving. Then, in this state, the loading platform P on the conveyor 17 stands by until the first stopper 22 moves up.

The transport mechanism 19 is composed of a known vertical slat conveyor or a slat of the vertical slat conveyor replaced with a belt piece. Then, it becomes possible to operate in synchronization with the stopper device 18 and place the loading platforms P sent out from the conveyor 17 one by one on the slats or belt pieces 31 and lift them up and send them out onto the carrying conveyor 7 during the carrying drive. There is.

According to the luggage carrier supply device shown in FIG. 4, the storage unit 17 stores the received luggage carrier P at a narrow interval.
Since the loading device P can be sent out by operating the stopper device 18 at a necessary time, the number of loading devices that are not in operation due to non-collection is reduced, and the total number of loading devices prepared in advance in the winding roll transfer device can be reduced. When recovering the loading platform, the empty loading platform can be placed on the loading platform return conveyor at any time, which simplifies the loading platform recovery work and allows multiple sheet platforms to be loaded at once in the sheet split winder. If you need it, you can deal with it. In addition, it is possible to store many cargo beds in a small space and save space. Further, since the carrier is supplied by using the transport conveyor 7, it is not necessary to separately provide a conveyor for sending the carrier to the unloading conveyor 5.

The carrier conveyor 7 supplied with the carrier P by the carrier feeder 15 can automatically convey the carrier P onto the machine side conveyor 6. Then, the loading platform P conveyed onto the machine-side conveyor 6 stands by on the machine-side conveyor 6 so that it can be supplied to the take-up roll receiving position immediately after the winding roll R is completed.

FIG. 6 shows a side view of the cross conveyor 9. According to this embodiment, the upper part of the downstream frame 32 provided along the longitudinal direction of the endless belt 10 of the cross conveyor 9 has the loading platform P.
Is a stopper member 33 for correcting the posture of the. The cross conveyor 9 is driven from a lowered position shown in FIG. 3 to a raised position by being driven by a dual process cylinder serving as a lifting drive device 13, and reaches a raised position shown by a chain line in FIG. 6 and an intermediate position shown by a solid line in FIG. be able to. The stopper member 33 of the cross conveyor 9 that has risen to the intermediate position projects into the path of the loading platform P on the transport conveyor 7. At this time, the upper end of the upstream frame 34 is lower than the upper surface of the endless chain 11 in order to pass the cargo bed P.
Further, the cross conveyor 9 is elevated to reach an intermediate position when the loading platform P is received from the transport conveyor 7.
Then, when the loading platform P reaches the intersection conveyor 9 and hits the stopper member 33, the transport conveyor 7 stops the transport after a predetermined time has elapsed. Therefore, the loading platform P transported by the transport conveyor 7 is prevented from being transported by the stopper member 33 and is pressed against the stopper member 33. Thereby, the platform P takes a fixed posture along the stopper member 33, and the posture is corrected. When the transportation of the transportation conveyor 7 is stopped, the crossing conveyor 9 is at the raised position,
The loading platform P is placed on the endless belt 10, lifted from the transport conveyor 7, and then transported to the intermediate conveyor 8.

In FIG. 1, when the intermediate conveyor 8 receives the loading platform P from the crossing conveyor 9, it waits until the loading platform P reaches the end of the crossing conveyor 9 on the side of the intermediate conveyor 8 and waits. The transport drive is started every time the loading platform P is sent out. Then, the received loading platform P is transported by a distance corresponding to the length and a predetermined spacing between the loading platforms, and the transport drive is stopped. By operating intermittently in this way, the mutual space between the loading platforms P received from the cross conveyor 9 can be reduced.

When the winding roll R is completed, the machine side conveyor 6 sends the loading platform P to the unloading conveyor 5. At the same time, the carry-out conveyor 5 carries the loading platform P sent from the machine-side conveyor 6 toward the take-up roll receiving position. Then, the machine-side conveyor 6 is driven and stopped so that the loading platform P sent out from the machine-side conveyor 6 is sequentially arranged from the furthest take-up roll receiving position to have an interval equal to the mutual interval of the take-up roll receiving positions. By repeating the above, the loading platform P is intermittently sent out. That is, the machine-side conveyor 6 functions as a loading platform supply mechanism for the carry-out conveyor 5. Then, the carry-out conveyor 5 is
When the loading platform P first sent out from the machine-side conveyor 6 reaches the furthest take-up roll receiving position, the transport drive is stopped.

FIG. 7 shows an embodiment of a control device for the machine side conveyor when the take-up roll is carried out. In FIG. 7, the control device 35 is configured by using a commercially available programmable sequence controller, and outputs a detection signal from a winding roll detection device 36 provided near the exit of the carry-out conveyor 5.
Further, it receives detection signals from detection devices 37 and 38 for individually detecting the transport distances of the carry-out conveyor 5 and the intermediate conveyor 8, respectively, and controls the motor 39 for driving the intermediate conveyor 8. The winding roll detection device 36 is a photoelectric switch, and the detection devices 37 and 38 are the motors 3 for driving the conveyance.
It is a pulse generator that outputs a pulse signal for each predetermined rotation angle of each of the output shafts 9 and 40.

The control device 35 includes a winding roll detection device 36.
When receiving the detection signal from the motor 39, the motor 39 is started and
The counting of the pulse signal from the detection device 37 is started. Then, the winding roll R1 obtains this count by the winding roll detection device 3
The width w1 of the winding roll R1 passing through the detection device 36 is detected by continuing until the winding roll detection signal is not input after passing through 6. Further, when receiving the detection signal from the winding roll detection device 36, the counting of the pulse signal from the detection device 39 of the conveyance distance of the intermediate conveyor 8 is started, and the conveyance distance of the intermediate conveyor 8 is obtained every moment. Then, when the conveyance distance of the intermediate conveyor 8 reaches a value obtained by adding the detected width w1 of the winding roll R1 and the preset gap d between the winding rolls, the rotation drive of the motor 39 is stopped. Then, when the next take-up roll R3 reaches the take-up roll detector 36 and a detection signal is output, the take-up roll R1 and the motor 39 are started, and the take-up roll R1 is received in the same manner as when the take-up roll R1 is received. When R3 is conveyed by the width w3 and the length of the gap d, the rotation drive of the motor 39 is stopped.

FIG. 8 shows an embodiment of a bed supply control device for automatically supplying the bed P to the take-up roll receiving position. FIG. 8 exemplifies a case in which four winding rolls are wound by the sheet dividing winding machine. Luggage supply control device 4
Reference numeral 1 denotes an input device 42 for inputting data relating to the split winding specifications for each split winding cycle, a central processing unit 43 for determining the number of necessary loading platforms and a target position of each loading platform based on the data, and a central processing unit. Necessary loading platform P found in 43
The stopper control unit 44 for controlling the stopper device 19 so as to send out the cargo bed P from the cargo bed supply device 15 based on the number of the above, the intermediate conveyor 8 and the carry-out conveyor for positioning the cargo bed P at the desired target position. 5 is composed of a conveyor control unit 45 for controlling the operation.

In the case of the embodiment shown in FIG. 8, the sheet dividing winder automatically controls the dividing position and the like by the slitter 3 when the division winding specification is changed.
6, the control computer 46 stores information about the width of the take-up roll, the length of the take-up roll, and the like. The data relating to the input device 42 via the data communication line, and the data is input to the input device 4
2 to the central processing unit 43.

The central processing unit 43 includes winding rolls R1 and R.
Data concerning the respective widths of 2, R3, R4, the dividing position by the slitter 3, and the winding position of each winding roll is received from the control computer 46, and based on the data, the winding rolls R1, R2, R3, R4 Position and
The number of loading platforms P required for each support is calculated by comparing a fixed reference value with the winding roll width. It should be noted that the position of each winding roll and the required number of loading platforms may be input via the input device 42. Further, since the front side winding position and the rear side winding position of the sheet split winding machine are the same in supplying the bed and unloading the winding roll, the description of the rear side winding position is omitted. In FIG. 8, since the width w1 of the take-up roll R1 is equal to or smaller than the reference value, the take-up roll R1 is formed by one loading platform P1.
Since the width w3 of the take-up roll R3 exceeds the reference value, the case where the take-up roll R3 is supported by the two platforms P2 and P3 is illustrated.

When the number of loading platforms on which the winding rolls R1, R2, R3 are placed is determined, the winding roll receiving position of each loading platform P1, P2, P3, that is, the target position of each loading platform is determined. Since the winding roll R1 is placed on the loading platform P1, the loading platform P1 is attached at the same position as the winding roll R1. Since the winding roll R3 is placed on the two loading platforms P2 and P3, the loading platforms P2 and P3 are positioned so as to be distributed equidistant from the center of the winding roll R3. At this time, the loading platforms P2 and P on which the winding roll R3 is placed
The distance d1 of 3 is equal to the distance b of each pair of both sides of the four endless chain of the conveyor 7 shown in FIG. Platform P
The distance d2 between 2 and the platform P1 is equal to one half of the sum of w1 and w3 minus d1 plus w2.
The distance l1 from the detection position of the detection device 49 to the target position of the loading platform P1 is equal to the distance a and w1 from the detection position of the detection device 49 to the slit position at the left end plus one half. Further, from the detection position of the detection device 49 to the loading platform P2,
The distances l2 and l3 of P3 are the sum of l1 and d2, respectively.
It becomes the sum of l2 and d1, and the transport distance l of the loading platform P3 is l3.
Is equal to the value obtained by adding one half of the length of the loading platform P3 to.

The stopper control section 44 commands the fluid pressure cylinder 30 at the time of supplying the cargo bed to operate the stopper device 18 to send out the cargo bed P. And stopper device 1
When the loading platform P sent out from No. 8 is detected by the detecting device 47, the fluid pressure cylinder 30 is instructed to prevent the loading platform P from being sent out. This operation is repeated until the detection signal of the detection device 47 is counted by the counting circuit and the count value reaches the number instructed by the central processing unit 43. By doing so, the necessary number of loading platforms P1, P2, P3 are sent out from the loading platform supply device 15. After that, the loading platforms P1 and P sent out
2, P3 are prepared on the intermediate conveyor 8 with a small mutual spacing as shown by the chain line.

The conveyor controller 45 controls the carry-out conveyor 5
The carrying distance of the cargo bed can be detected moment by moment by counting the pulse signal from the detecting device 37 with the counting circuit. In addition, the loading device P is detected by the detection device 48 including a photoelectric switch provided near the exit of the intermediate conveyor 8.
2, P3 can be detected. When the start signal is received, the motor 3 for driving the conveyance of the intermediate conveyor 8
9 is driven to rotate, and at the same time, the transport driving motor 40 of the carry-out conveyor 5 is driven to rotate.

Then, at the same time that the top loading platform P3 is sent to the unloading conveyor 5 side, at the same time, the loading platforms P2 and P3 are also transported by the intermediate conveyor 8, and then the loading platform P2 moves to the vicinity of the exit of the intermediate conveyor 8 and the detecting device. Detected at 48. In addition, the discharged cargo bed P3 is a conveyor 5 for unloading.
Is transported to the receiving position. It is detected by the detection device 49.

Thereafter, the conveyor control unit 45 determines that the loading platform P
2. Whenever P2 is detected by the detection device 48, the motor 39
The motor 39 is stopped each time it is detected based on the pulse signal from the detection device 37 that the loading platforms P3 and P2 have been conveyed by d1 and d2 from the position P3 shown by the chain line in FIG. Restart the rotation drive of. Then, after the load P3 is detected by the detection device 49, the drive of the motor 40 is stopped when the transport distance becomes equal to 1, and the drive of the motor 39 is stopped when the last load P1 is sent out. With this, each of the loading platforms P3, P2, and P1 comes to the take-up roll receiving position. It is possible that detection of the transport distance by the unloading conveyor 5 is started at the same time when the transport of the intermediate conveyor 8 is started and the detection device 49 is not provided, or that the transport distance of the intermediate conveyor is detected. In addition, the method of detecting the transport distance of the loading platform and the method of obtaining the target position of the loading platform can be variously changed.

A second embodiment of the winding roll conveying device is shown in FIGS. 9 and 10. In this embodiment, the loading platform P is supplied from a loading platform supply device 15 provided at the end of the unloading conveyor 5 opposite to the transport conveyor 7 side. In FIG. 10, the loading platform feeder 15 lowers the loading stations P one by one from the lower end onto the unloading conveyor 5 and a storage unit 17 that stacks and stores the loading platforms P so as not to fall along the vertically extending guide member 17a. It is composed of a stopper device 18 which is released by releasing. The stopper device 18 has a pair of forks 51 that can move up and down and move horizontally.

The fork 51 is slidably supported by a horizontal guide mechanism 53 which is provided on a vertical guide mechanism 52 and which is driven to move up and down.

The present invention has been described above with reference to a few examples, but the embodiments can be variously changed without changing the gist of the invention. For example, in the above-described embodiment, the cross conveyor in the machine side conveyor is a belt conveyor and the transfer conveyor is a chain conveyor. However, the cross conveyor is a chain conveyor capable of moving up and down, and the transfer conveyor is shown in FIG.
A belt conveyor having a belt that is stretched under the endless chain at the intersection with the endless chain as shown in FIG. Further, in the above embodiment, the machine side conveyor and the carry-out conveyor are belt conveyors, but they may be replaced with roller conveyors. The transport conveyor shown in FIG. 1 is a common chain conveyor that intersects the front and rear machine side conveyors and is driven by one transport driving motor (not shown), so the structure is very simple. Not limited to this, the chain conveyor may be used only at the intersection with the machine-side conveyor, and the others may be belt conveyors or roller conveyors.

Further, in FIG. 2, the carry-out conveyor 5 is
It is located below the take-up roll R supported by the take-up arm 4, moves from the retracted position shown by the chain line to the lower side of the take-up roll R supported by the take-up arm 4, receives the take-up roll, and winds it. Arm 4
However, although the carry-out is started after retracting from the released take-up roll R, the carry-out conveyor 5 may be provided on the front side of the take-up position of the sheet split winder 1 as shown in FIG. In FIG. 11, the sheet split winder 1 winds by supporting a winding roll R on the tip end of a winding arm 4 which is swingable around a shaft 54 parallel to the width direction of the strip-shaped sheet. When the roll is wound up, the take-up arm 4 is tilted toward the front as shown by the chain line, and the take-up roll R is released on the loading platform P prepared on the carry-out conveyor 5. Further, the carry-out conveyor 5 shown in FIG.
Is provided on the conventional unloading carriage 55, and the winding roll R
When the sheet is received, it is moved to the machine side of the sheet dividing and winding machine 1 together with the unloading carriage 55 and is connected to the machine side conveyor.

Further, the delivery of the take-up roll from the sheet dividing winder to the carry-out conveyor is not always performed directly from the take-up arm to the loading platform on the carry-out conveyor. As described in No. 217452, a take-out device for hoisting and taking out the take-up roll is simultaneously hoisted above the take-up arm 4 and prepared as shown in FIG. 11 along the front and back take-up positions. After being conveyed above the conveyor 5, it may be moved in the horizontal direction and lowered onto the conveyor for unloading. Also, instead of the lifting device, a forklift or other transfer mechanism may be used.

Further, the sheet dividing winder may be one in which the take-up roll is supported by the lower end portion of the take-up arm and is wound up, and the take-up roll is released on the carry-out conveyor arranged below the take-up arm. . Further, as the carry-out conveyor, depending on the structure of the sheet dividing and winding machine, it is possible to employ one that can be moved up and down to receive the winding roll and one that is fixed along the winding position. Further, the winding rolls are not limited to be received all at once and may be received one by one.

The transport conveyor may be commonly provided between the two sheet dividing winders arranged in parallel. Further, in the above-described embodiment, the winding roll is conveyed in the radial direction, but the present invention is not limited to this, and a roll that conveys the winding roll in the central axis direction can be used. When the transport conveyor transports the take-up roll in the central axis direction, the machine-side conveyor receives the take-up roll carried in the central axis direction from the carry-out conveyor, and the take-up roll is placed in the crosswise conveyor conveyor. Since it is fed in the direction of the central axis, a belt conveyor, a chain conveyor, a roller conveyor or the like provided on a turntable rotatable about a vertical axis can be provided instead of the cross conveyor shown in FIG. And, in that case, the belt conveyor or the chain conveyor or the roller conveyor on the turntable is in series with the carry-out conveyor to receive the take-up roll from the carry-out conveyor together with the loading platform, and the take-up roll is taken from the carry-out conveyor. After receiving, it rotates together with the above-mentioned table and contacts the conveyor, and sends out the winding roll in the direction of its central axis.

The machine side conveyor may be provided with a movable conveyor as shown in FIG. 11 instead of the intermediate conveyor and the cross conveyor shown in FIG. Then, this conveyor is made movable to a position connected to the carry-out conveyor and a position connected to the transfer conveyor. In that case,
A turntable is provided at the intersection of the longitudinal axes of the transport conveyor and the unloading conveyor, and after the winding roll sent from the unloading conveyor is received on the conveyor, the conveyor is moved to the turntable, The take-up roll may be transferred to the conveyor by connecting the conveyor to the tip of the conveyor by rotating the turntable. Further, in place of the intermediate conveyor and the cross conveyor shown in FIG. 1, a carry-out conveyor movable to the machine side as shown in FIG. 11 is provided, and the carry-out conveyor is placed on the above-mentioned turntable and rotated to carry out the carry-out conveyor. The take-up roll may be passed directly from the transfer conveyor to the transfer conveyor, and the intermediate conveyor and the cross conveyor shown in FIG. 1 may be eliminated. Further, the machine side conveyor may be manually operated when the take-up roll is passed to the transfer conveyor.

The carrier does not necessarily have a data carrier regardless of its shape. Further, instead of the loading platform supply device 15 shown in FIG. 9, it is also possible to employ, for example, one equipped with a loading platform lifting mechanism as described in the first embodiment.

In FIG. 1, the loading platform P is supplied to the conveyor 7 from the lifting mechanism 19 of the loading platform feeder 15, but the loading platform feeding unit feeds the loading platform to one end of the crossing conveyor 9 opposite to the unloading conveyor 5. It is efficient to provide each of them and to simultaneously supply the loading platform P to the carry-out conveyors at the front and rear winding positions. Then, instead of the machine side conveyor including the intermediate conveyor 8 and the cross conveyor 9 in the first embodiment, a cross conveyor having the same structure as the cross conveyor of the first embodiment may be provided as the machine side conveyor. Also, in FIG.
In the case where the loading platform is fed from the machine-side conveyor 6 shown in FIG. 9 or a conveyor provided adjacent to the unloading conveyor 5, the mutual distance between the take-up roll receiving positions is smaller than the feeding spacing of the loading platform P from the loading platform feeder 15. Getting smaller,
If it becomes larger, compare the spacing between the take-up roll receiving positions and the delivery interval of the loading platform from the loading platform feeding device, and find the mutual spacing between the loading platforms fed from the loading platform feeding device than the mutual spacing between the winding roll receiving positions. When is large, the drive of the machine side conveyor may be temporarily stopped to reduce the mutual space between the loading platforms received from the loading platform supply device.

Further, the loading platform supply device is not limited to the one that feeds the loading platform from above the unloading conveyor or on the extension line of the unloading conveyor, and the loading platform may be transferred in the intersecting direction of the unloading conveyor. Moreover, in order to supply the loading platform to the take-up roll receiving position, a conveyor provided on the trolley is used, and the loading platform is placed on the unloading conveyor at the intervals corresponding to each winding roll receiving position. Place it on the machine side of the take-up machine in advance, and immediately before releasing the take-up roll, move the carry-out conveyor with the carriage to a position where the take-up roll is released, and place the loading platform placed on the carry-out conveyor at each take-up roll receiving position. You may turn it on.

According to the present invention, the take-up roll can be carried out to the machine side in a short time, and the take-up roll carried out to the machine side of the sheet divided winding machine can be conveyed without handing over by the worker. As a result, it is possible to increase the transportation efficiency without increasing the labor and to increase the operation rate of the sheet dividing winder. In addition, the transport conveyor transports the take-up roll that has been unloaded to the machine side of the sheet split winder in the crossing direction of the unloading conveyor, so that the transport route avoids the installation space for the winding roll processing equipment in the center of the building. Can be arranged. Therefore, it is possible to effectively use the equipment space without the labor of the operator.

When the take-up roll is placed on the carrier and conveyed, the take-up roll, which is easy to roll, can be stably supported and can be conveyed without damaging the take-up roll or equipment. Further, it is not necessary to lower the take-up roll from the loading platform and load it on another loading platform, and the identity of the loading platform and the winding roll can be reliably maintained. Therefore, it is suitable for the case where the loading platform is equipped with a storage device and a large amount of information about each winding roll is conveyed together with the winding roll.

When the carry-out conveyor carries the take-up rolls in the central axis direction and the carry conveyor carries the take-up rolls in the radial direction, a large number of take-up rolls are placed on the carry conveyor even if the short carry path is short. Since it can be temporarily stored, the take-up roll does not have to be unloaded from the transport conveyor in the next apparatus to wait for processing, and the floor area can be saved, which is convenient.

When the machine side conveyor is provided with a crossing conveyor that intersects with the above-mentioned transporting conveyor, the transfer position of the take-up roll on the transporting conveyor can be adjusted by the crossing conveyor. It can be mounted securely at the required position.

When the machine side conveyor is provided with an intermediate conveyor between the crossing conveyor or the rotary conveyor and the unloading conveyor, the take-up roll can receive the loading platform from the unloading conveyor regardless of the operation of the transport conveyor. When completed, the take-up roll can be carried out from the carry-out conveyor at any time.

When the carry-out conveyor is provided movably between the machine side and the inside of the sheet dividing and winding machine, the carry-out conveyor can be moved to the machine side when receiving the take-up roll. Since the withdrawal of the carry-out conveyor from the winding position can be completed at the same time, the waiting time until the start of the next winding preparation can be shortened, and the apparatus can be simplified.

If the take-up rolls are placed on one or a plurality of loading platforms according to their widths and transported, the loading platforms can be made compatible with each other, thereby stabilizing the winding rolls during transportation. It is possible to maintain the property, and further, to increase the space occupied for transportation without increasing the space, and to simplify the handling such as preparation, storage, and recovery of the loading platform.

When the loading platform is conveyed to the take-up roll receiving position by the unloading conveyor, the operator does not need to carry the loading platform to the winding roll receiving position, which saves labor and facilitates automatic feeding of the loading platform. become.
