Description

TECHNICAL FIELD The present invention relates to the structure of a winding section in a slitter winding machine.

(Prior Art) Conventionally, in the winding portion of this type of slitter winding machine, it is possible to move on a sliding guide base provided in the width direction of the belt-shaped sheet,
Further, there are a type in which it is supported so as not to come off from the base, and a type in which it is movably and detachably supported on a sliding guide base provided in the width direction of the belt-shaped sheet. In this case, any type of winding unit is provided with a base unit supported on the guide base and a drive source provided for each winding unit or for each winding unit on one side or both sides of the distribution. Thus, the portion supporting the winding shaft and the like which is rotatably driven is handled as a unit.

(Problems to be solved by the invention) In a slitter winding machine, there is a strong demand for diversification of division specifications in which thin sheets of various widths are simultaneously and appropriately wound, and therefore, It is necessary to use a winding part having a structure corresponding to each narrow width, but it is extremely difficult to deal with this by using a winding part of the above type.

That is, when dealing with the former form, a large number of winding portions having various specifications are prepared on the sliding base, and the winding portion suitable for winding the narrow sheet is selected from the winding portions. The unit is moved to a predetermined position without being removed from the base.

However, even if it is dealt with as described above, since the winding parts on each side are linearly arranged, it is impossible to replace the adjacent winding parts. The problem is that the specifications are regulated, and division specifications that are not suitable for the arrangement structure of the winding section cannot be performed
Having more than the required number of take-up units at all times means that not only the manufacturing cost but also the take-up unit waiting place in the device is needed, which increases the space occupied by the device. Problem, in relation to the above, if many winding parts on the sliding base are attached from the standby position to the predetermined position, the moving distance becomes longer by that much, and it is not used in the winding. Since the winding section also needs to be moved to a different standby position, it takes a lot of time to move the winding section when the split specification is changed. In some cases, the shaft drive mechanism is provided, and since the winding unit itself is less required to support the wound sheet roll and is necessary, it has a considerable weight. Therefore, a considerable amount of labor is required to push and pull the entire winding section by hand to move it. In addition, since the slitter winding machine is usually structured such that the sheet roll corresponds to the position where the operator can easily perform the work, the base of the winding section exists at a very low position. Therefore, it is very difficult to push and pull this in a bad posture to accurately position it at a predetermined position.

Further, also in the case of dealing with the latter type, the same is done as the former. In the latter type, the winding unit can be detached from the sliding base, so that in principle any division specifications can be dealt with, and many standby positions are not provided. However, even in the case of such a form, the base portion of the winding portion, which is heavy, can be slid in the width direction of the sheet without shaking during the preparation for winding, while the base portion of the winding portion is firmly fixed during winding. Since it must be fixed on the base, the problem that a special structure that meets those requirements is required for the base part and becomes complicated,
If the take-up part is once removed from the base and then installed, the sliding clearance between the take-up part and the position of the heavy take-up part in the seat width direction can be finely adjusted each time it is supported. Since the parallelism and position between the winding shaft and the touch roller, etc., to be secured must be maintained in a state of being accurately maintained, a skilled element for the operator is indispensable,
Also, there is a problem that a considerable amount of work time is required to adjust the sliding clearance and the alignment. As described above, the sliding base of the winding section exists at an extremely low position. Since the mechanism for attaching to and detaching from the base in the winding section is located at a lower position below that, the work is extremely difficult and the workability is extremely high. The problem of being bad, etc. will remain.

(Means for Solving the Problems) Therefore, the present invention divides a wide strip-shaped sheet into a plurality of narrow strips and sorts the strips vertically or horizontally, and distributes each sorted narrow strip in the width direction of the strip-shaped sheet. In a slitter winder that is supported by a winding unit movable to the inside and is wound around a winding shaft or a winding core externally attached to the winding shaft that is rotationally driven by a drive mechanism, each of the winding units is , A base that is movable on a guide base provided in the width direction of the belt-shaped sheet, and a winding support that is supported by the base, and one of the base and the winding support has a projection for alignment. And a concave portion for alignment is formed on the other side.

(Operation) Accordingly, in the winding unit of the present invention, the base movable in the width direction of the strip-shaped sheet and the winding support are detachable,
A winding shaft support portion or a base portion having a structure according to the width of the sheet, the weight of the rolled-up sheet roll, the required torque for winding the sheet, or both can be appropriately combined. When changing the take-up part due to a change in the split specification, remove the reel support part and position only the base part with a small weight first, and then remove the desired reel support part in the noble part. Can be installed.

(Embodiment) FIG. 1 is a first embodiment of the present invention showing a side surface of a winding portion, and FIG. 2 shows a relationship between a winding shaft support portion and a base portion.

The base 1 is supported by a guide base provided along the width direction of the strip sheet S, in this case a slide rail 2, and moves on the guide base 2 in the width direction of the strip sheet S. It is possible. A winding arm that supports a winding shaft C, in this case, a shaft support portion 7 in which a swing arm 5 is swingably supported by a support shaft 6, is detachably attached. 5 and the shaft support portion 7 constitute a winding shaft support portion. The winding shaft C penetrates the base portion 1 and rotates the common drive shaft 8 driven by a motor (not shown) to the gear 9a and the shaft support portion 7 attached to the base portion 1 and engaged with the common drive shaft 8. Mounted gear 9b,
A gear 9c coaxially attached to the support shaft 6, a gear 9d attached to the winding arm 5, and a powder clutch as a winding torque adjusting means.
Transmission is performed via the output shaft 11 of the gear 9e and the pulley 12a, the belt 13 and the pulley 12b at the tip of the gear 9e through the gear 9e so that the gear 9e is rotationally driven with a required winding torque. Reference numeral 14 has one end connected to the take-up arm 5 and the other end connected to the shaft supporting portion 7, and the swing angle of the take-up arm 5 is adjusted to adjust the surface of the sheet roll R and the touch roller T.
It is a fluid pressure cylinder that adjusts the contact pressure on the surface. In this case, the powder clutch 10 controls the winding torque, so
An electric wire therefor can be connected and disconnected by the connector 15. Reference numeral 16 denotes a flexible duct which accommodates electric wires and the like therein and moves together with the base 1. Reference numeral 17 is a concave groove formed on the upper surface of the base portion 1, and 18 is a convex portion formed on the lower surface of the shaft supporting portion 7. Then, by engaging the convex portion 18 with the concave groove 17, the base portion 1 and the shaft supporting portion 7 are aligned, and the bolt 19
Both are fixed by. When the base portion 1 and the shaft support portion 7 are separated, the bolt 19 may be loosened and then the engagement between the two may be released. The gear 9a of the base portion 1 and the gear 9b of the shaft supporting portion 7 are engaged with each other at a predetermined interval by engaging the base portion 1 and the shaft supporting portion 7. Although the common drive shaft 8 of this embodiment penetrates the base portion 1, it may not be penetrated, and the common drive shaft 8 may be supported by another stand that moves together with the base portion 1. In that case, the arrangement of gears and the like may be appropriately changed. The winding torque adjusting means may be not only a powder clutch but also a friction sliding clutch, and the installation location thereof may be obtained in the shaft support portion 7 and the base portion 7.

Although only one type of winding shaft support portion (the winding arm 5 and the shaft support portion 7) is shown in the drawing, the weight of the sheet roll R to be wound varies depending on the width of the wound sheet. Since it changes, for example, a winding portion made of a material that can withstand winding a heavy sheet roll, and a winding portion for winding a normal general weight sheet roll are appropriately prepared.
It goes without saying that they are used properly according to the division specifications.
When applied to the actual winding of the slitter, the winding shaft support portion (the winding arm 5 and the shaft support portion 7) not required for winding is removed, and the base portion 1 is placed between the pair of winding portions during winding. It is possible to make it exist, or when changing the split specification, first move only the base part 1 to a position according to the split specification, and then attach the winding shaft support part (rewinding arm 5 and shaft support part 7) of the required standard. it can.

And K is a slitter blade.

FIG. 3 is a side view of a slitter winding machine including a winding section according to a second embodiment of the present invention, and FIG. 4 is a pair of winding sections for winding one of the divided narrow sheets. FIG. In the slitter winding machine itself, the strip-shaped sheet S fed out from the lower side of FIG. 3 passes through various guide rollers and the slitter blade K
Since it is a well-known structure in which it is divided into a required narrow width by means of and is distributed to the left and right through the touch roller T, detailed description thereof will be omitted.

This embodiment differs from the winding section of the first embodiment in that the winding motor 5 has a drive motor M for driving the winding shaft C attached thereto. The motor M in this case has a torque adjusting function, and transmits its drive to the winding shaft C via the belt 13. Incidentally, also in the case of this embodiment, the shaft support portion 7 and the base portion 1 are separable. The drive motor M may be a hydraulic motor or the like.

FIG. 4 shows a state in which the sheet roll R is wound up by the pair of winding portions. In this case, the motor M is attached only to the left take-up arm 5, and the right take-up arm 5 merely serves to rotatably support the winding shaft.
This is because the sheet to be wound is narrow, and the sheet can be wound by the driving force of only the motor M attached to the left winding arm 5. Therefore, when the torque of the motor M on one side becomes insufficient due to the widening of the narrow sheet due to the change of the split specification, in this drawing, the right winding shaft support portion (the winding arm 5 and The shaft support 7 of the shaft support 7) may be separated from the base 1, and the winding shaft support (the winding arm 5 and the shaft support 7) on which the motor M is mounted may be mounted on the base 1.

FIG. 5 is a side view of the winding portion in the third embodiment of the present invention, and FIG. 6 is an enlarged view showing the engaged state of the base portion 1 and the shaft support portion 7. What is different from the previous embodiment is that firstly, the winding shaft driving motor M is attached to the base portion 1, and secondly, the convex portion 20 is formed on the upper surface of the base portion 1 and the lower surface of the shaft supporting portion 7. That is, a groove 21 is formed in the groove. In addition, the gear 9f of the base 1
It goes without saying that the gear 9g of the shaft support 7 and the gear 9g of the shaft support 7 engage with each other by engaging the projection 20 of the base 1 and the groove 21 of the shaft support 7.

The point of exchanging the winding shaft support portion (the winding arm 5 and the shaft support portion 7) according to the weight of the sheet roll to be wound is the same as in the previous embodiment. When the winding section is actually applied to a slitter winding machine, for example, two types of motors M to be mounted on the base section 1 (motor for high load, motor for normal load) are prepared and appropriately divided into the base section 1. If it is attached, the winding shaft support portion (the winding arm 5) having a structure suitable for the width of the sheet to be wound.
It is possible to combine the shaft support portion 7) and the base portion 1 provided with the motor M capable of generating the required winding torque.

Incidentally, 9f, 9g and 9i are gears.

FIG. 7 is a fourth embodiment of the present invention and shows a side surface of a slitter winding machine including a winding section.

The difference from the above-described embodiment is that the winding support is
It has changed to. That is, this slitter winder
Guide rail 2 which is rotated by the drive of fluid pressure cylinder 23
A support arm 22 detachably attached to the base 1 supported by the
The winding shaft C is rotationally driven by the driving motor M attached to the. Further, the touch roller T is provided for each sheet roll, and the touch roller T is a hydraulic cylinder.
24 is different in that it is pressed against the surface of the sheet roll.

On the other hand, the support arm 22 and the base portion 1 are integrated by engaging the concave groove formed on one side with the convex portion formed on the other side, and are separated by releasing the engagement, which is the same as the above-described embodiment. . A motor may be attached to the base, or the drive of the common drive shaft may be transmitted to the winding shaft via a powder clutch or the like as in the first embodiment.

FIG. 8 is a plan view showing a state in which sheet rolls R ₁ , R ₂ and R ₃ having various widths are wound by a slitter winding machine using the winding portion of the present invention. The winding portion is the second embodiment. I use the one. As is clear from the drawing, the sheet rolls R ₁ , R ₂ and R _{3 in the} order of increasing width are the winding shafts supported by the pair of winding arms 5a and 5a, 5b and 5b, 5b and 5c, respectively. It is wound by C ₁ , C ₂ and C ₃ . And in this case, since the winding Toude 5a is that a drive motor M for each high load (not shown), since suitable for winding a wide sheet width, by supporting the winding axis C ₁ , Used for sheet roll R ₁ . The winding arm 5b is provided with a drive motor M for a normal load, and the winding arm 5c merely has a function of rotatably supporting the winding shaft. A pair of winding Toude 5b, and 5b used the sheet roll R ₂ of the width of moderate accordance connexion to wind winding shaft C _2, winding one to winding shaft C ₃ to wind the narrow sheet roll R ₃ The take-up arm 5b and the other take-up arm 5c. In this case, the winding shaft C ₂ is driven to rotate at both ends.
A motor M for driving a rotary shaft of a winding shaft to wind a sheet having a divided width which is about twice as large as that when driven on only one side like C _3.
Applicable within the rated torque range. Further, since the winding portion not used for winding is separated into the base portion 1a and the winding shaft support portion (the winding arm 5 and the shaft support portion 7), the base portion 1a is provided between the pair of winding portions during the winding of the sheet. Waiting The bases 1 and 1a are common bases, and which base supports which winding shaft support (winding arm 5).
Whether or not to attach the shaft support 7) can be appropriately selected.

Although the present invention has been described above with reference to a few examples, it goes without saying that the embodiments are appropriately changed and applied depending on the well-known technology of the designer and the situation such as the installation site of the apparatus.

For example, a dovetail-shaped convex portion conforming to the shape of the groove formed on the lower surface of the winding shaft support may be inserted into the dovetail groove formed on the upper surface of the base portion, or a knock pin or the like may be used. Good.

The widthwise movement of the belt-shaped sheet of the base may be performed by providing a pinion on the base, laying a rack that meshes with the pinion along the guide base, and turning the pinion with a handle or the like. . The pinion may be driven by a motor, or the drive screw shaft may be rotated.
The base can be moved by a combination of engagement and disengagement operation of the female screw provided on the base, a combination of a non-driving screw shaft, a female screw screwed to the screw shaft provided on each base, and a driving motor thereof. Then, it becomes easy to deal with automatic positioning of the base.

(Effect of the Invention) According to the present invention, the winding shaft support portion can be attached to and detached from the base portion that is movable on the guide base, and the combination according to the narrow sheet can be performed. It is possible to change the specifications of the sheet roll wound by one slitter winder in various ways without restricting the slitter winder due to the convenience of the slitter winder. Since the base portion can be present in a state where the winding shaft support portion is removed, a space for saving the space can be achieved without providing a waiting place for the winding portion. Further, when moving, only the base portion needs to be moved, so that it is possible to reduce the work labor.

Further, since the base is not removed from the guide base, a special structure for that purpose is unnecessary. Moreover, when changing the take-up part due to the change of the split specification, the winding shaft support part is removed, and only the base part having a small weight is moved first to be positioned and fixed at a predetermined position, and then the base part is simply fixed. If a predetermined winding shaft support portion is aligned and fixed by fitting the convex portion and the concave groove to each other, the alignment can be performed easily and accurately. Therefore, it is not necessary for the operator to push and pull the heavy-weight winding portion every time when the reassembling is performed to adjust the position or adjust the sliding gap, as in the conventional case. It will be possible to perform in a comfortable posture, shortening the reassembling work time, improving work efficiency,
It is possible to eliminate the skill element of the operator.
