Description

Description: TECHNICAL FIELD The present invention relates to a belt-shaped member winding device capable of automatically winding the tip of the belt-shaped member around a bobbin with an air jet output from a rotary nozzle.

[Prior Art] As a winding device for a belt-shaped member of this type, there is a device described in, for example, Japanese Patent Application Laid-Open No. 1-176761.

This conventional technique is a web winding shaft having a suction hole for adsorbing a web on a peripheral surface thereof, and a web winding blade having a web end scooping claw providing a web end on the peripheral surface of the web winding shaft, A web winding belt characterized by comprising a web winding belt that is moved by being in contact with a peripheral surface of the winding shaft for winding a web end provided by a web winding blade on the peripheral surface of the web winding shaft. It is a device.

In addition to this, there is one described in JP-A-60-15340.

In this prior art, a web continuously running at a substantially constant speed is cut into a plurality of narrow strips by dividing the web into a plurality of narrow strips. Adjacent strips of web are alternately distributed to two or more winding sections and are individually separated. In a multi-strand winding device for a web wound around a winding core, a turret arm that swivels around a central portion and a gripping portion that is pivotally supported at both ends of the turret arm and is expandable and contractible in a radial direction are provided. A chuck part that holds the strip, a cutter that travels in the traveling direction of the strip web to cut the strip web at a predetermined length, and a winding core that winds around the strip leaving at least the entrance path of the strip web. A power transmission system for connecting a chuck portion and a rotary drive source by arranging a winding belt by juxtaposing a narrow web between the winding belt and a wrapper belt for winding the elongated web around a winding core. Each of the wafers is provided with a torque varying device. Which is a multi-start winding device.

[Problems to be Solved by the Invention] Of these conventional examples, the former, that is, JP-A 1-17
No. 6761 is complicated by an air suction type web winding shaft that requires a complicated and expensive rotary seal bearing, a web winding belt that is largely displaced by a large number of displacement control members, and a complicated cam shape. The web winding is finally started to be wound around the suction type winding shaft by the extremely complicated and diverse play of the above-mentioned respective members of the web winding blade and the rake blade which are displaced to each other.

Therefore, this conventional example has a problem that the operation becomes complicated and diversified, requires a large operation space, the apparatus becomes large and heavy, and the apparatus becomes expensive in combination with the complicated structure. There is also a big problem in the roll paper shipping and distribution system that the web cannot be wound around the bobbin of the hole.

Further, the latter conventional example, that is, JP-A-60-15340.
Since the direction and position of the air nozzle with respect to the winding core are fixed at the time of winding the web, the air jetting direction is set at the web winding starting point of the winding core, It is a trumpet belt that is laid over a roller and that is displaced in a wide variety of ways so that the starting end of the web can be wound onto the core.

Therefore, this conventional example also requires a trumpet belt and an air nozzle that are displaced in a wide variety of complicated ways. Therefore, a large operation space is required and the overall size is increased.
There is an essential and big problem that the weight is increased and the apparatus becomes complicated and expensive.

In order to eliminate the above-mentioned problems, the present invention uses an air jet output from a simple air nozzle rotating around the bobbin and a folding action by a pressing arrow to automatically move the vicinity of the end of the belt-shaped member to the outer peripheral surface of the bobbin. It is intended to be wrapped around.

[Means for Solving the Problems] An object of the present invention described above is to provide a support member at a position for receiving a hanging portion of a band-shaped member wound in a roll shape in a device that starts winding while pressing the band-shaped member against a rotating bobbin. A rotating shaft rotated by a motor is horizontally provided horizontally by a cantilevered support, and a pressing roller for contacting / separating the strip-shaped member with an outer peripheral surface of an elongated bobbin fitted on the rotating shaft is attached to a bracket and a fluid cylinder. An air nozzle, which is arranged on the support member by a drive source, and which rotates most of the periphery of the bobbin planetarily by a motor, is arranged by a bracket in parallel with the rotation axis, and further rotates around the bobbin. A pressing force for folding the tip of the strip-shaped member wound around most of the periphery of the bobbin by the air jet output from the air nozzle between the strip-shaped member coming from above and the outer peripheral surface of the bobbin. This can be achieved by disposing the arrowhead on the support member above the rotary shaft via a drive source such as a bracket and a fluid cylinder.

Alternatively, the air nozzle may be cantilevered by a bracket rotatably fitted to the bobbin insertion member support shaft, and a plurality of air outlets may be provided in the length direction.

Further, the air outlet opened in the air nozzle may be opened in a position where an air jet is generated in a tangential direction with respect to the bobbin inserted into the rotary shaft.

Further, the supporting member may be configured such that a belt-shaped member supply reel mounting member and a cutter for cutting the belt-shaped member are provided above the supporting member.

[Operation] The belt-shaped member winding device according to the present invention is a tangential air jet output to the bobbin from the air nozzle that planetarily rotates around the horizontally installed bobbin in the rotation direction of the bobbin.
It is possible to wind a part of a predetermined range of the lower part of the strip member that hangs parallel to the bobbin around the outer peripheral surface of the bobbin while blowing it up against the gravity.

After that, the pressure roller presses the strip-shaped member with the action of the drive source such as the fluid pressure cylinder into pressure contact with the bobbin that rotates at a low speed, and slowly starts to feed the strip-shaped member. However, it is possible to start winding the band-shaped member around the bobbin by folding the tip end portion of the band-shaped member between the band-shaped member coming from above and the low-speed rotating bobbin.

After that, the bobbin insertion member is rotated at a high speed by the motor to wind the strip-shaped member.

The pressing arrow and the nozzle have been returned to the positions before the start of the operation before that, and are ready for the next winding.

When a certain amount of the strip-shaped member is wound around the bobbin, the rotation of the bobbin is stopped, the strip-shaped member is cut by the cutter, and the wound bobbin can be replaced with a new one to perform the next winding.

The cutter 17 is attached to one surface of the support member 1 as shown in FIG. 1, and has a construction in which a drive source such as a plunger is installed so that a cutter blade 28 wider than the width of the belt-shaped member a can be inserted and removed.

The stopper pin is designated by reference numeral S in each of FIGS. 1 and 6 to 11.

The belt-shaped member winding device according to the present invention has the above-described structure. The operation of this device will be described below.

A belt-shaped portion wound in a pre-roll (for example, a thin synthetic resin sheet, a thin, slippery paper having a silicon resin processed on the surface) a has its lower portion started to rotate as shown in FIGS. 1 and 6. As shown in FIG. 7, the weight 8 hangs between the nozzle 8 at the point and the bobbin b attached to the rotary shaft 3.

This hanging means may be self-weight hanging as described above, but may be forced hanging.

As shown in FIG. 7, when it is detected by a sensor (not shown) that the supply reel 16 is rotating to the predetermined position by the rotation of the arrow, the motor 7 is started and the bracket 8A is rotated at a low speed.
The air nozzle 8 attached to this rotates around the bobbin b.

Air is ejected from the air outlet 14 of the nozzle 8 in the tangential direction of the bobbin b, and the lower predetermined length of the belt-like member a is blown up by the air ejection force from the nozzle, as shown in FIG. The bobbin b can be started to be wound with the rotation with respect to the surface.

Along with this winding operation, the drive source 5 such as a fluid pressure cylinder operates to press the pressing roller 6 against the bobbin b with the strip-shaped member a interposed therebetween.

Around the end of this pressure contact, the motor 2 is started to rotate the rotating shaft 3 and the bobbin b at a low speed.

Therefore, the strip-shaped member a can be forcibly pulled out from the supply reel this time, and the vicinity of the tip thereof is the pressing roller 6
Just before contacting the strip-shaped member a between the bobbin b and the bobbin b, that is, when the nozzle 8 reaches the turning end point, a sensor (not shown) detects this state and drives the fluid pressure cylinder or the like shown in FIG. Operate source 10.

Then, as shown in FIG. 9, the bracket 9 to which the pressing arrow 11 is attached is rotated toward the contact point between the bobbin b and the pressing roller 6, and as shown in FIG. While being folded back in a V shape by the jetting force and the pressing force of the pressing arrow 11, it is folded between the peripheral surface of the bobbin b and the belt-shaped member a coming from above, and the winding of the belt-shaped member a around the bobbin peripheral surface is completed.

When the winding of the belt-shaped member a onto the bobbin b is completed, the drive source 10 such as a fluid pressure cylinder is operated again, and the bracket 9 is attached to the shaft.
It rotates counterclockwise about 35 as a fulcrum, and the pressing arrow 11 retracts.

When this backward movement is detected by the sensor, the motor 2 rotates at a high speed to wind the belt-shaped member a from the belt-shaped member supply reel 39 onto the bobbin b at a high speed.

This winding amount is detected by a sensor (not shown), and the motor 7 starts to rotate at a low speed just before the winding of the predetermined amount is completed, and the motor 7 is stopped after the winding of the predetermined amount is completed.

The air nozzle 8 that has already stopped the ejection of air when the motor 7 is stopped returns to the pre-start position when the motor 2 is reversed, and the bracket 4 is operated by the operation of the drive source 5 such as a fluid pressure cylinder.
Moves clockwise around the shaft 30 as a fulcrum, and separates the pressing roller 6 from the belt-shaped member a as shown in FIG.

When the pressing roller 6 separates from the belt-shaped member a, the cutter 17 operates to cut the belt-shaped member a which is taut, as shown in FIG.

After this, the bobbin b on which the winding of the belt-shaped member a is completed is rotated by the rotary shaft 3
Then, the next bobbin is inserted and the strip member a is again wound on the bobbin b from the strip member supply reel 39 in a fixed amount.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

The tangential air jet output to the bobbin from the air nozzle that planetarily rotates around the horizontally installed bobbin in the rotation direction of the bobbin, and the predetermined range of the lower part of the belt-like member that hangs parallel to the bobbin , The bobbin can be wound around and intimately attached to most of the outer peripheral surface while blowing up against the gravity.

After that, the pressure roller is pressed by the operation of the drive source such as the fluid pressure cylinder to the bobbin which rotates at a low speed with the belt-shaped member interposed therebetween, and the belt-shaped member is slowly fed, and the pressing force is applied by the action of the drive source such as the fluid pressure cylinder. By folding the front end of the belt-shaped member between the belt-shaped member coming from above and the low-speed rotating bobbin, the belt-shaped member can be started to be wound around the bobbin.

Therefore, the air suction winding shaft and the web winding belt that move in various ways with the complicated structure required in each of the above-mentioned conventional examples, the wrapper belt with a large number of rollers, the large displacement, the large size, the large weight, and the expensive price. The present invention has the first and second effects that the member can be completely dispensed with in the present invention and that smooth paper can be properly automatically wound even on a bobbin having no holes.

In particular, according to the present invention, even in the first stage, the lower predetermined length portion of the belt-shaped member immediately after the start is automatically brought into close contact with most of the bobbin peripheral surface by the air jet output by the air nozzle that revolves around it, and the tip of the belt-shaped member is By folding the part between the bobbin and the belt-shaped member coming from above, the winding can be started reliably and automatically, and even long paper with extremely slippery surface treatment such as silicon-coated paper can be securely wound. It is possible to start winding, and it is easy to link with the winding process after that,
In particular, it is possible to reliably cut the wound sheet that is tensioned by applying tension only with the cutter blade, and it is possible to fully automate the winding, thus reducing the cost of winding roll paper etc. There is also a third effect to say.

In addition, a wide strip-shaped member can be pressed evenly and closely to the outer peripheral surface of the bobbin with the air jetting force evenly over the entire width of the bobbin so that the strip-shaped member can start winding automatically without any scratches or wrinkles. There is a fourth effect that can be done.
