Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strip-shaped, relatively wide paper sheet or a flexible film such as a resin film which is wound into a roll and unrolled while being split in the width direction. The present invention relates to an automatic core supplying device for automatically supplying a tubular core (such as a paper tube) used as a rewinding core to a winder that performs rewinding.

[0002]

2. Description of the Related Art In a winder as described above, a core used as a core for rewinding is usually of a sheet width to be obtained even if it has the same diameter (the width of each of the slit webs is not limited to the width). Equivalent)
40 to 50 types (approximate length 5
(A wide range of 0 cm to 250 cm) may be used.

In the above-mentioned winder, for example, Japanese Unexamined Patent Publication No.
As described in JP-A-99747 and JP-A-6-40621, a plurality of (not necessarily the same length) cores are required for one winding operation (one wholesale). A posture in which the book cores are laid down side by side manually or by a core automatic feeding device one by one, for example, between a pair of winding drums provided in a winder as described later (horizontal posture).
And the cores are arranged in series along the length direction (if necessary, a spacer for centering and connection is inserted between the inner peripheral portions of the cores). By raising and lowering both ends of the aligned body in accordance with the increase in the winding diameter while holding and rotating the pair of chucks supported in a vertically movable manner, each of the divided slitted webs is placed on the outer periphery of each corresponding core. It is made to wind up at the same time.

[0004] When the winding diameter (roll diameter) of the web wound on the core reaches the set winding diameter, the winding roll with the core is discharged to the outside. Is supplied between the winding drums. The supply of cores to winders as described above has traditionally relied on manual labor, but if it relies on manual labor, productivity is poor, and so-called multi-various types that use various types of cores with different lengths in particular In the case of small-lot production, the type (length) of cores to be supplied frequently changes, so that erroneous supply of cores is likely to occur and a great deal of labor is required for workers. In order to improve productivity and save labor, attempts have been made to automate the supply of such cores.

Several automatic core supplying apparatuses for automatically supplying cores to a winder have been proposed up to now, but the following will briefly describe a representative apparatus as shown in FIG. 27. . It should be noted that those shown in the drawings refer to those described in JP-A-8-99747.

An automatic core supply device 500 shown in FIG.
Is a required number of cores that are arranged in parallel and arranged in parallel, with the upper surface and the left and right side surfaces opened to stow and store the cores c (ca, cb, cc, cd) in a staggered manner in the horizontal position. Containers 600, 600, ... (4 in the figure)
Table), a pickup transport device 510 that sequentially picks up the cores c stacked in the core storage container 600 in a horizontally laid state from above and transports the cores along the arrangement direction of the containers 600, and is not shown. However, there is provided a core delivery device including a tilt table or the like that rolls or moves the core c conveyed by the pickup conveyance device 510 and supplies the core c to the winder.

The pickup transfer device 510 includes a traveling platform 513 that reciprocates on a rail 511 laid on the floor surface by a motor 512 by, for example, a rack-pinion system, and a guide column erected on the traveling platform 513. 515 and a motor 517 along the guide post 515.
An arm 520 that is moved up and down by, for example, a rodless cylinder or a screw feed method by driving, a rodless cylinder 522 attached to the lower surface side of the arm 520, and a carriage 525 that is moved in the left-right direction by the rodless cylinder 522. And a holder 530 attached to the lower surface side of the carriage 525 to hold the uppermost core c in the container 600 by suction, for example, by vacuum suction.

Here, the core storage container 600
Are arranged side by side along the direction in which the rails 511 extend, and each of the containers 600, 600,... Has a different type (having substantially the same diameter but different length) of cores ca, cb. , Cc and cd are stacked in a staggered manner in the vertical direction in the posture of being laid horizontally as described above, in other words, are stored horizontally.

More specifically, only the longest core ca (code is irrelevant to the length) is arranged in one row in the leftmost container 600 in the figure, and the adjacent container 600 is relatively short. The core cb has two rows along the length direction, the adjacent container 600 has two relatively long cores cc along the length direction, and the rightmost container 600 has the shortest core cd. Each of the three rows is stacked along the length direction.

The automatic core supplying apparatus 500 having such a configuration is generally controlled by a computer according to a predetermined program. That is, for example, the type and order of the cores c to be supplied to the winder are programmed in advance, and the core automatic supply device 500 stores the cores c to be supplied by the traveling platform 513 in response to a command from a computer. The arm 520, the carriage 525, and the suction tool 530 are moved and lowered while aiming at the center of one of the cores c located at the uppermost stage of the container 600. The core c is sucked and held by the holding tool 530, and thereafter, the arm 520, the carriage 525, and the sucking tool 530 move and ascend in reverse order, and the traveling platform 513 travels to the front end or the rear end of the rail 511, for example. The core c is transferred to the core sending device or the like, and thereafter, the same operation is repeated, and the core c required in the winder is repeated. One by one and supplies. In this case, the core c is loaded into the winder, for example, by being rolled in a horizontal position in which the core is laid down.

[0011]

However, in the conventional automatic core supplying apparatus as described above, the cores c are stacked and stored in a staggered manner in the vertical direction in a state of being laid horizontally on the container 600. In relation, the following problems have occurred. That is, the cores required in the winder are not necessarily the same kind of core, and in particular, in the case of multi-product small-lot production, in each winding operation and one winding operation, Many types of cores having different lengths are often used, and 40 to 50 types of cores may be required in one day.

However, in the conventional apparatus, since the cores are stacked horizontally in the container, only the uppermost one of the cores stacked in one container or one row can be taken out. For this reason, the degree of freedom at the time of core removal is extremely low, and when dozens of types of cores are required, a considerable number of containers are required, and they are arranged along the rail, or It is required that the row of cores or the container storing the cores be replaced according to the type of core to be supplied to the winder.

In this case, arranging a large number (for example, 15 or more) of containers requires a large space, and especially when the core is placed horizontally as described above, the occupied space on a plane becomes large. This is virtually impossible due to space constraints in the building, and the distance traveled from taking out cores from each container to the winder becomes longer depending on the number of containers. It takes a long time to carry, and there is a possibility that productivity may be significantly reduced.

[0014] Frequent replacement of a row of cores or a container containing the same in accordance with the type of cores to be supplied to the winder requires a great deal of time and effort, and also complicates management and reduces productivity. At the same time, erroneous supply of cores (incorrect type of core supplied to the winder) is likely to occur. If the erroneous supply of the cores occurs, the position of the core used for the current winding operation in the winder shifts as it is, so that the web cannot be properly wound on each core and they are wasted. For this reason, if a mistake is made in the core, such as by checking the type of core that is being supplied, the core is replaced manually, but replacing the core manually requires a great deal of trouble. This is cumbersome, during which time all lines are shut down, resulting in a significant reduction in availability.

In addition to the above, in the conventional automatic core supply device, the outer peripheral portion of the uppermost one of the cores stacked in a staggered shape in the container is sucked and held by the holder and taken out. In such a method, the position of the core is not constant, and the core may be broken and the position may be largely shifted when the core is sucked and held by the holder.
In particular, when the computer is automated to take out the core according to a predetermined program, when the core is taken out, the holding tool (the taking-out tool) and the core do not align with each other.
Problems such as a situation where the core cannot be taken out or a situation where the core is dropped may occur frequently.

[0016] The operation schedule of the winder is greatly restricted due to the above-mentioned problems in the automatic core feeding device. In other words, it is not possible to set an operation schedule that frequently changes the type of core to be supplied to the winder, and it is not possible to completely automate the supply of cores even when performing multi-product small-lot production. There were many parts to rely on. In addition, it was not possible to flexibly respond to changes, corrections, additions, etc., in the operation schedule of the winder.

The present invention has been studied from the stage of storing the cores in order to solve the conventional problems as described above. The purpose of the present invention is to frequently replace cores and containers. The cores of the required type can be taken out without fail, and core management can be performed easily and accurately.Moreover, it is possible to deal with automation and labor saving of multi-product small-lot production, and rational transport of cores. Can be applied to existing winders without modification.
Furthermore, it is possible to flexibly respond to changes, corrections, additions, etc., in the operation schedule of the winder, thereby improving productivity and improving the operation rate of the winder. It is an object of the present invention to provide a core automatic feeding device which is made possible.

[0018]

In order to achieve the above-mentioned object, an automatic core supplying apparatus according to the present invention basically comprises a core for rotating a winding core in an upright posture so as to lie down. A reversing means; and a core sending means for receiving the core laid down by the core reversing means and sending the core to the winder.

As a more preferred specific example, a core extracting / conveying means for extracting a plurality of tubular cores stacked in a vertical position in order from the top, and conveying the extracted core in the front-rear, left-right direction. Core reversing means for receiving and rotating the core conveyed by the core extracting and conveying means to lie horizontally, and core sending means for sequentially sending out the core laid horizontally by the core reversing means to the winder, The core reversing means has an outer peripheral chucking portion composed of a pair of grippers for selectively gripping / releasing the cylindrical outer peripheral portion of the core, and the chucking portion is rotated by about 90 degrees by driving means such as a motor. Let it.

Further, in a preferred aspect, at least one gripping surface of the gripping portions of the chucking portion is in a horizontal plane so that when the core is opened to release the core, the core rolls out therefrom. It is inclined to. In a preferred embodiment of the automatic core supply device of the present invention, the core is placed in an upright posture in a container, that is, a configuration in which a conventionally placed core is placed vertically and stored is taken out. Is pulled out along the length direction, and is rotated so as to lie on the side thereof and sent out to the winder, so that the following operation and effect can be obtained.

[0021] Cores of different types (having substantially the same diameter and different lengths) can be individually stored in a predetermined number of vertical chambers provided in the container. Therefore, various types of cores can be stored in one container. it can. In each of the vertical chambers, cores can be stacked in series along the length direction, so that one vertical chamber can accommodate a plurality of types and a plurality of cores. Specifically, if the height of the vertical chamber is 180 cm, for example, the length is about 75 c
m can be stacked in three levels, and up to about 120 cm in length can be stacked in two levels (more than one level only). If the total length is up to about 240 cm, multiple layers can be stacked. The core can be housed in one vertical room. In this case, even if a part of the core protrudes from the vertical installation chamber, there is no problem in storage, transportation, removal (extraction), and the like.

Since the position of the core accommodated in each vertical chamber is regulated by the members defining the vertical chamber, undesired behavior does not occur and the core is maintained at a fixed position. For this reason,
The correct storage position of the core can be easily grasped, and even when the computer is automated to take out the core according to a predetermined program, the position of the take-out tool is properly matched to the core at the time of taking out the core (at the time of taking out). As a result, the required core can be reliably and quickly removed from the container.

Comparing the case where the core is placed horizontally and the case where the core is placed vertically from the viewpoint of space, the projected area of the vertically placed core is much smaller than that of the horizontally placed core. Since more types of cores can be arranged efficiently within a certain plane space, the number of types of cores that can be selected at the time of core removal increases, and the degree of freedom in selection can be increased. As the degree of freedom in selecting the core is increased, the restrictions imposed on the operation schedule of the winder are reduced. Further, even when the operation schedule of the winder is changed, or when the type of cores to be supplied to the winder is frequently changed and a multi-product small-lot production is performed, it is possible to flexibly respond flexibly.

For the reasons described above, many types of cores do not require a large space, are easy to store and take out, have a high degree of freedom in selection at the time of taking out, and are easy to grasp the storing position. Thus, the core of the required type can be surely taken out without the necessity of frequently changing the core or the container.

In addition to the above, when the core is automatically supplied to the winder by the automatic core supplying apparatus of the present invention, each of the vertical chambers of the container is individually provided in consideration of the order in which a plurality of types of cores to be supplied to the winder are to be supplied. One or more of the cores are stored vertically and core storage position information indicating which core is stored in which vertical storage chamber is stored in any one of the vertical chambers. Using the core storage position information, the vertically stored cores are sequentially extracted according to a supply schedule created based on the operation schedule of the winder and are sent out to the winder, so that the core management is performed. It can be performed easily and without fail, and can flexibly respond to changes, corrections, additions, etc., of the operation schedule of the winder.

Further, by identifying the type of the core moving toward the winder, even if the type of the core is mistakenly stored in the container,
By collating the operation schedule of the winder, the core supply schedule, and the core storage position information,
It is possible to easily find a core that has been erroneously transferred, take a countermeasure quickly, and reduce the possibility of erroneous supply of the core.

On the other hand, the core conveyed by the core extracting / conveying means is rotated so as to lie down on the side, and then sent out toward the winder, so that the core is laid down in a normal posture. Because it can be loaded into the core pocket, it can be applied to existing winders without modification. Further, after the core is rotated, the core can be rationally conveyed by being conveyed via an upwardly-moving elevator, a transfer tilt table, a mounting and transferring means, a buffer means, a pushing and loading means and the like.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an outline of a core supply management system including an embodiment of an automatic core supply device according to the present invention, and FIG. 2 is a flowchart showing a setup for supplying cores.

In the core supply management system of the illustrated embodiment, first, a required number of core storage containers 200 (here, for example, four) are prepared as shown in FIGS. The container 200 is basically composed of a plurality of types for winding (having substantially the same diameter but different lengths) and a plurality of cores c.
(C ₁ , c ₂ , c ₃ ,...) Can be stacked in the length direction and accommodated.
(A total of 72 rooms in 9 rows vertically and 8 rows horizontally) are provided in a grid pattern.

Specifically, the container 200 is assembled so as to have a rectangular box-like outer shape as a whole, and defines a bottom plate 201 made of a flat plate, a rectangular lattice frame 202, and the vertical installation chamber 210. A mesh-shaped partitioning top plate 205, reinforcing rods 219 crossed over four outer peripheral surfaces of the frame 202 to reinforce the frame 202, and casters 220 arranged near four corners of the bottom plate 201, respectively.
The whole is movable.

As can be seen clearly from FIGS. 6 and 7, each of the vertical chambers 2 in the partition
Partition rods 212 that contact the peripheral side surface of the core c and regulate the position thereof are provided upright at predetermined intervals so as to connect them between the central part of the four sides defining the base 10 and the bottom plate 201. Are located.

The partition rod 212 is made of a metal pipe made of aluminum or the like having a circular cross section. A part of the outer periphery of the partition rod 212 protrudes inside each of the vertical chambers 210 defined by the partition top plate 205. . The overhang amount is set according to the diameter of the core c to be stored, and the distance between the partition rods 212 to 212 facing each other in each of the vertical chambers 210 is slightly (1-2 mm) larger than the diameter of the core c. Only about many. Therefore, the core c completely or partially accommodated in the vertical chamber 210 is prevented from behaving and deflecting in the radial direction by the four partition rods 212 surrounding the core c.

The partition rod 212 has a tapered upper end in the vicinity of the partition top plate 205 in order to facilitate the insertion and removal of the core c into and out of the vertical chamber 210. Core storage container 200 as described above
Is prepared, based on the operation schedule of the winder 300 (indicated by a phantom line in FIGS. 1 and 11) that winds up sheets such as strips of paper (sheets) while dividing and slitting the sheets into predetermined width dimensions. Then, a supply schedule of the core is set.

The operation schedule of the winder 300 is as follows.
For example, the production amount, type, production order, etc. of the target day are determined according to the order amount and the delivery date. For example, as shown in FIG. 8 using the personal computer PC3 (FIG. 1) or the like. Is set as a list. The operation schedule of the winder 300 shown in FIG. Indicates the manufacturing order (the order of the winding operation), and six rows (No.
001, 685, 685, 765, 765,...) Indicate the length (unit: mm) of the core used for the winding operation, and the numerical value on the right side thereof (No. 001).
, 4920) indicates the total length, and the rightmost end indicates the number of wholesales (the number of times the winding operation is repeated). As can be seen from this operation schedule, in the winder 300, a maximum of six cores c having different lengths are used in a single winding operation, and multi-product small-lot production is performed.

From the operation schedule, the type of the core c required by the winder 300 on the target date,
The number, the required time (order), and the like are known, and the supply number, type, order, and the like of the cores c are determined based on the information, and the core supply schedule is set. Next, based on the supply schedule, a plurality of types of cores c (c ₁ , c ₂ , c ₃ ,...) Corresponding to the number to be supplied to the winder 300 are prepared,
The prepared plural kinds of cores c (c ₁ , c ₂ , c ₃ ,
..) Are stored in the containers 200, 200,.

In this case, in the container 200, the cores can be stacked in series along the length direction, so that a plurality of types and a plurality of cores c can be stored in one vertical chamber 210. Specifically, for example, as shown in FIGS. 3 to 5 described above, assuming that the storage unit length of the container 200 (the height of the vertical installation room 210) is 180 cm, for example, the length is up to about 75 cm. Objects (for example, core c ₃ ) can be stacked in three layers, and those having a length of up to about 120 cm (for example, core c ₄ ) can be stacked in two layers (more than one layer only). If it is up to about 240 cm, a plurality of cores can be stored in one vertical chamber 210.

When storing the cores c in the containers 200, the order in which the cores c are to be supplied is taken into consideration, that is, different types (lengths) of cores c are stored in one vertical chamber 210.
If for accommodating the (e.g. core c ₁ and c ₂ in FIG. 3-5),
Each of the vertical chambers 210 (there are 72 chambers) of the container 200 is provided with 1
Store in a book or a plurality of books vertically (this work is done manually). And any vertical room 2 of any container 200

The core storage position information is recorded as information represented as a list as shown in FIG. 9 using, for example, the personal computer PC1 (FIG. 1). The core storage position information shown in FIG. 9 indicates how many (how many) cores c are contained in what row and in what column in the container 200.
It also indicates the diameter (mark) and length of the cores, and the core storage position information is recorded on an information recording medium such as a floppy disk, a hard disk, or an MO. In the list shown in FIG. 9, the same type of core c is stored in one vertical chamber 210, but the different types (different in length or diameter) of core c are stored as described above. May be. Further, in the list of FIG. 9, marks having different colors (red and blue) indicate those having slightly different diameters (for example, 109 mm and 110 mm are substantially the same).

On the other hand, as shown in FIG. 1, the core storage position information is transmitted to a personal computer PC2 for performing inventory management and core production management by a communication line via a hub HUB, a server CU, and the like, and to the winder 300. And a computer CC1 for performing core removal and transfer control in the core automatic supply device 10 (exchanging information such as a picking instruction, a picking result, and an abnormality log with the PC). ), A computer CC2 that performs core inversion and transmission control, and the type of core c being transferred to the winder 300 (length,
The mark is also transmitted to a measurement computer CC3 or the like to which sensors VS for detecting and identifying the mark are connected.

As can be clearly understood from FIGS. 12 and 13, the core extracting / conveying device 20 drives a motor 23 on a pair of rails 12 laid in parallel on the machine frame 11. For example, an X-direction moving base 21 that reciprocates in the front-rear direction (XX ′ direction) by a rack-pinion method, and a pair of rails 24, 24 disposed on the X-direction moving base 21 are moved by a motor 27.

The inner peripheral chucking portion 47 is located at a lower position, and the lower limit positions of the inner peripheral chucking portions 37 and 47 are not shown, but the inner peripheral chucking of the pickup mechanism 30 is not shown. The portion 37 is located at a position lower than the inner peripheral chucking portion 47 of the pickup mechanism 40.

As described above, the inner peripheral chucking portions 37 and 47 are provided.
The reason why the ascending limit position and the descending limit position are different is that the ceiling height of the building is limited, and when the relatively long core is extracted and the relatively short core is extracted, the above-mentioned chucking is performed. This is because the positions to be taken by the king portions 37 and 47 are different.
Can pull out a relatively short core c located on the bottom side of the container 200, and
The length of each part is set so that a relatively long core c protruding upward from the container 200 does not collide with the ceiling.

Further, comparing the case where the core c is placed horizontally and the case where the core c is placed vertically, from the viewpoint of space, the planar projection area of the vertically placed core c is much larger than that of the horizontally placed core c. Since it is small, the space efficiency is good, and more types of cores can be arranged in a certain plane space. Therefore, the types of cores that can be selected at the time of core extraction are increased, and the degree of freedom of selection can be increased. When the degree of freedom in selecting the core c is increased, the restrictions imposed on the operation schedule of the winder 300 are reduced. In addition, winder 30
Even when there is a change in the operation schedule of 0, or in the case of performing multi-product small-lot production in which the type of core to be supplied to the winder 300 changes frequently, it is possible to flexibly respond flexibly.

For the reasons described above, many types of cores c do not require a large space, are easy to store and easy to take out, and have a high degree of freedom in selection at the time of taking out. It can be easily stored in a container, and the core of the required type can be surely taken out without frequently changing cores and containers.

Further, the automatic core supplying apparatus 1 of the present embodiment

In consideration of the order in which the containers are to be supplied, one or a plurality of tubes are stored vertically in each of the vertical chambers 210 of the container 200, and which type of core is stored in which vertical chamber in which vertical chamber. Record the core storage position information indicating
Then, in the automatic core supply device 10, the core storage position information is reproduced and used by the computers CC1 and CC2 and the like, and the vertically stored core c is transferred to the winder 300.
The core c can be easily and definitely managed, and the operation schedule of the winder 300 can be changed. , Correction, addition, etc.

Further, a core type identification device V comprising a length measuring sensor VS1, a tip detection sensor VS2, and an outer diameter (mark) identification sensor VS3 attached to the transfer device 100.
S identifies which type (length, diameter) of the core c is sent to the winder 300, and the identification information is used as a personal computer PC for performing the inventory management and the core production management.
2 and the personal computer PC3 for setting the operation schedule of the winder 300, and the computer CC1 for controlling the extraction and transfer of the core c, the computer CC2 for controlling the core inversion and transmission, and the like, and are used there. Incorrect supply of cores is unlikely to occur, and even if the type of the core c is mistakenly stored in the container 200, the operation schedule, the core supply schedule, and the core storage position information of the winder are compared with each other, so that the core c is incorrectly transported. You can easily find out which cores you have and take quick measures.

Further, since the core c is laid on the side of the winder 300 and pushed in along the length direction, it can be applied to the existing winder without any modification. Also, after rotating the core, the elevator 70,
The core can be rationally conveyed by being conveyed through the transfer tilt table 80, the on-board transfer device 100, the buffer device 120, the pushing and loading device 150, and the like.
