Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a chuck mechanism for sandwiching and locking a group of tapes arranged in parallel at a predetermined interval, and withdrawing the group of tapes in a uniform state. For drawer device for
It can be used for a device for producing a lattice-like web by drawing out the transverse tape group in the cross direction with respect to the sequentially fed vertical tape group, and fusing the intersecting portions to each other.

[Background technology]

Some synthetic resin materials of recent years have extremely high strength only in a specific direction. When using such a material with strong directionality in a sheet shape, it is necessary to secure strength in two directions along a plane. There is. For this purpose, the material is formed into a film and laminated so that the respective strength directions intersect with each other, and the material is formed into an elongated tape shape extending in the strength direction, and the resin tapes are crossed with each other. They are arranged in a direction to form a grid-shaped web.

Here, in order to manufacture a grid-like web from such a resin tape, a method of weaving using a loom has been generally used. However, when using a loom, horizontal tapes are fed one by one between vertical tapes by a so-called shuttle, so that the basic operation speed is slow and improvement in manufacturing efficiency has been required.

On the other hand, the applicant of the present invention has proposed a device for manufacturing a grid-like web by fusing a resin tape at a high temperature by utilizing the thermoplasticity of the resin material instead of weaving the resin tape.

In this device, a plurality of resin tapes are arranged in parallel at a predetermined interval to form a vertical tape group, and a similar horizontal tape group is pulled out in the cross direction with respect to this vertical tape group, and the crossing portions of each other are heated to high temperature. It is constructed by fusing with a press etc., separating the horizontal tape group, and then sequentially feeding the vertical tape group to wind up the lattice web in the vertical direction, which requires shuttle operation like a loom. Since it does not exist, the work speed is high, and extremely efficient manufacturing is possible.

[Problems to be Solved by the Invention]

By the way, in the above-mentioned fusion-type lattice-shaped web manufacturing apparatus, the steps of pulling out the lateral tape group, fusing, and cutting are sequentially repeated.

Of these, in the drawing step, it is required that all the tapes forming the lateral tape group be reliably drawn until the tip reaches the opposite side of the vertical tape group. It is necessary to consider tension, posture, etc. so that the tape is stretched evenly.

In addition, in the resin tape used for these grid-like webs, the tip portion may be warped or twisted due to cutting before drawing, and if the state or posture of many tapes is not uniform, At that time, it was difficult to securely lock each tip.

For this reason, in these drawing steps, it is necessary to manually adjust each tape or to perform the drawing itself, but it is not possible to obtain a constant result manually, and work efficiency or burns at the time of fusion heating are caused. From the viewpoint of safety, it has been required to develop a mechanism or device that can automate these operations.

An object of the present invention is to provide a chuck mechanism for a plurality of parallel tape groups capable of automatically performing a reliable locking even if the states of a plurality of tapes are not uniform, and a plurality of tapes automatically in a reliable and uniform state. An object of the present invention is to provide a pull-out device for pulling out a plurality of parallel tape groups.

[Means for Solving the Problems]

The parallel tape group chucking mechanism of the present invention is provided with a pair of holding members capable of holding the tip portions of the parallel tape groups in close proximity to each other, and these elastic members are formed on the inner surface of each of them. Providing an aligning means for engaging the protrusions and recesses with the convex and concave grooves and advancing toward the tip side along the sandwiched tape group to align the tip end portion of the tape group,
The aligning means is configured to be inserted between the holding members when advancing.

Further, the parallel tape group drawing device of the present invention is provided with a pinch roll mechanism for sandwiching and sending the parallel tape group between the rigid surface roll on the driving side and the rolling elastic surface roll, and feeding from this pinch roll mechanism. A chuck mechanism for sandwiching and locking each tip of the tape group to be held and a pull-out mechanism for moving the chuck mechanism in parallel in the pull-out direction are provided.

Here, the chucking mechanism of the parallel tape group of the present invention described above can be used as it is as the chucking mechanism of the drawing device.

Further, as a more specific configuration of the drawer mechanism,
It is possible to adopt a configuration in which a pair of driving means for reciprocally driving both end portions of the chuck mechanism and a tuning means for matching the moving positions of the both end portions are provided. Of these, a rodless cylinder can be used as the driving means, a combination of a guide and an electric motor can be used, and the tuning means is a pair of chains or belts arranged along the movement paths of the both ends. It is possible to use a configuration in which a circulation transmission mechanism is provided, these are interlocked with each other, and a part of each of them is connected to corresponding both ends.

[Action]

In the chucking mechanism of the parallel tape group of the present invention configured as described above, when the plurality of tapes to be locked are uneven with warping or twisting at the tip portions, the holding members are separated from each other to the full extent. Although it may not be possible to insert the leading end of each tape as it is, the leading end portion of each tape is aligned by advancing the aligning means before sandwiching, and each tape is inserted by the aligning means. The tip of the tape can be surely inserted between the holding members.

In this state, the aligning means is retracted to bring the holding members close to each other, so that the respective tapes are held between the respective holding members. At this time, the sandwiching member is engaged with each of the tapes by the ridges and the grooves so that the tapes are partially curved so that the tape is firmly locked. However, by making the ridge an elastic body, damage to each tape can be avoided.

Therefore, according to such a parallel tape group chucking mechanism, even irregular tape groups can be reliably clamped, and strong locking is performed with the clamping, and reliable locking is automatically performed by these. The purpose of doing is achieved.

On the other hand, in the parallel tape group drawing apparatus of the present invention, the chuck mechanism holds and holds the respective tip portions of the plurality of tapes, and the chuck mechanism is moved in parallel in a predetermined direction by the pulling mechanism to move the tape from the tip side. In addition to pulling out like this, by positively and evenly feeding out each tape to be pulled out by the pinch roll mechanism, the burden of clamping by the chuck mechanism is reduced and locking failure etc. are avoided, and pinch of each tape The tension and posture of the portion between the roll mechanism and the chuck mechanism are constant.

Especially when feeding by the pinch roll mechanism,
The rigid surface roll is used as the driving side to maintain the peripheral speed accurately, and the elastic surface roll ensures that each tape follows the surface of the rigid surface roll for accurate feeding operation. Twisting is prevented.

Therefore, according to such a parallel tape group pulling device, it is possible to reliably pull out all the tapes forming the tape group until the tip ends reach the opposite side of the vertical tape group, and , It becomes possible to stretch each pulled-out tape in a state in which tension, posture, etc. are uniform, and by these, the purpose of performing reliable and uniform pull-out automatically is achieved.

The chuck 80 and the alignment member 87 constitute a chuck mechanism.

The manufacturing operation of the lattice web 13 in this embodiment will be described below.

First, by heating the tape group 11 passed through the table 52 and the tape group 12 superposed on the table group 52 while lowering the heating plate 53 and sandwiching it between the tape group 11 and the table 52, The resin tapes 10 constituting 12 are pressed against each other at their intersecting portions, and are melted and fused by heating,
The grid-shaped web 13 is formed on the table 52.

The fusing is followed by cutting with the cutter 55 (cutting line C in FIG. 4), whereby the web 13 on the table 52 is separated from the tape group 12 on the side of the feeding device 40. At the time of this cutting, the tape group 12 is pressed by the pressing member 65 of the guide mechanism 62, and the tip end portion is maintained at the cut position.

Next, the feed roll 24 of the supply device 20 is rotated for a predetermined time, and the tape group 11 is fed. Where the tapes
The tip end side of 11 is wound around the winding roll 33 of the winding device 30 and a constant tension is applied by the torque motor 35, and the tape group 11 is fed by a predetermined feed amount S1 (see FIG. 4). The feed amount S1 matches the width of the tape group 12, and the webs 13 formed on the table 52 are sequentially fed to the winding machine 30 side S1 one by one and wound around the coil 13A. On the table 52, a new tape group from the supply device 20 side
11 will be sent. Each tape in this tape group 11
Motor 26 on the sending side and motor 35 on the winding side
A uniform tension is applied according to the rotating force of the tapes 10, and the posture and position of each tape 10 are adjusted by the guide grid 27 and the guide mechanism 61 of the supply device 20.
Are maintained on the table 52 in a uniform state.

Then, the cylinder 71 of the pull-out mechanism 70 is operated to move the chuck 80 to the supply device 40 side, and the tip of the tape group 12 is locked by the chuck 80.

As shown in FIG. 9, each of the tapes 10 of the tape group 12 is warped or twisted apart due to the cutting by the cutter 55. There is no.

As shown in FIG. 10, by advancing the aligning member 87 toward the tip end side by the cylinder 88, the tape group 12 is sequentially leveled and the respective tapes 10 are roughly grouped and can be inserted into the opening 84 of the chuck 80. Becomes In this state, the chuck 80 is brought closer.

As shown in FIG. 11, as the chuck 80 approaches, the aligning member 87 is inserted into the opening 84, whereby the tip of the tape group 12 is introduced into the opening 84. When the cylinder 82 of 80 is contracted to bring the sandwiching members 81 and 83 close to each other and the aligning member 87 is retracted by the cylinder 88 at an appropriate stage, the leading end of the tape group 12 is left sandwiched in the opening 84. .

As shown in FIG. 12, when the sandwiching members 81 and 83 come closer to each other, the front end of the tape group 12 is sandwiched between the sandwiching members 81 and 83. At this time, the sandwiched tape group 12 is bent in a wavy shape by the ridges 85 and the groove 86, and the edge portions of the tape groups 12 reliably lock the tape group 12.

When the chuck 80 has locked the tip,
80 is moved to the opposite side of the tape group 11 to pull out the tape group 12. That is, the cylinder 71 is operated in the reverse direction to apply the driving force to the chuck 80 in the direction opposite to the supply device 40. In this state, the chuck 80 does not move because the tape group 12 is restricted in movement, but the holding member 65 of the guide mechanism 62 is lifted to release the nipping of the tape group 12, and the feed roll 44 of the supply device 40 is moved to a predetermined position. By rotating for a time, the chuck 80 moves to the opposite side of the tape group 11 with the front end of the tape group 12 locked,
12 is sent by a predetermined feed amount S2 (see FIG. 4). The feed amount S2 is set to be slightly larger than the width of the tape group 11, and a new tape group 12 is superposed on the tape group 11 stretched on the table 52 previously. A uniform tension is applied to each tape 10 according to the driving force of the motor 46 and the cylinder 71 on the delivery side, and the tape grid 12 and the guide mechanism 62 of the supply device 40 are applied to each tape group 12.
The posture and position of each tape 10 are adjusted by
Each tape 10 is brought into a uniform state. In practice, since the tape group 12 is stretched between the chuck 80 and the aligning member 87, there is a space between the tape group 11 and each tape group 11,
12 can be pressed against each other by lowering the heating plate 53.

As a result, new tape groups 11 and 12 are prepared on the table 52, and thereafter, the same fusing, cutting, feeding operation of the tape group 11, and pulling-out operation of the tape group 12 are repeated to perform the web operation.

And can be fully automated for manufacturing the web 13.

Further, the feeding operation of the tape group 11 can be controlled by the motor 26 of the supply device 20 and the torque motor 35 of the winding device 30.

Among them, in the supply device 20, the pinch roll mechanism by the pinch roll 23 and the feed roll 24 can accurately perform the intermittent feeding operation of the tape group 11. Therefore, even if the pull-out resistance from the coil 11A is large, the winding device 30 is not overloaded, or the tape group 11 and the web 13 in the middle are not overloaded, and a stable feeding operation is performed. Can be realized.

In addition, since the guide grid 27 is provided in the supply device 20 and the guide mechanism 61 is provided immediately before the table 52, the state of the tape group 11 to be fed can be adjusted to prevent the tapes 10 from being twisted or biased.

As a result, the entire feeding operation of the tape group 11 can be accurately and reliably performed, and the tape group 11 stretched along the table 52 can be brought into a predetermined uniform state.

On the other hand, the pulling operation of the lateral tape group 12 is performed by the feeding device 40.
Can be controlled by the motor 46, the holding member 65 of the guide mechanism 62, the cylinder 71 of the pull-out mechanism 70, and the chuck 80.

Among these, in the supply device 40, the intermittent feeding operation of the tape group 12 can be accurately performed by the pinch roll mechanism including the pinch roll 43 and the feed roll 44. Therefore, even if the pull-out resistance from the coil 12A is large, an excessive load is not applied to the pull-out mechanism 70, an excessive tension is not applied to the tape group 12 in the middle, and a stable feeding operation can be realized.

Further, since the guide grid 47 is provided in the supply device 40 and the guide mechanism 62 is provided immediately in front of the table 52, the state of the tape group 12 to be fed can be adjusted to prevent the tapes 10 from being twisted or biased.

Further, the guide mechanism 62 is provided with a pressing member 65 so that the tip end of the tape group 12 after cutting can be maintained at the position as it is, and the chuck 80 can reliably lock the tape group 12 when it is pulled out.

Further, since the alignment member 87 is provided at the tip of the tape group 12,
Even if the tape 10 at the tip end is twisted or warped, it can be put together by the aligning member 87, so that it can be easily and surely inserted into the opening 84 when being locked by the chuck 80.

Further, the tip end of the tape group 12 has a holding member 81 of the chuck 80,
It is sandwiched by 83, and is caught in a wavy shape by the convex strip 85 and the concave groove 86 to be securely locked. At this time, since the ridge 85 is made of an elastic material, it is appropriately deformed according to the rigidity of each tape 10, and there is no risk of damaging the tape 10 by being bitten more than necessary.

Further, the chuck 80 that locks the tip of the tape group 12 can be moved to the opposite side of the tape group 11 by each cylinder 71 of the drawing mechanism 70. At this time, the chuck 80 can be moved in parallel by the synchronizing means by the sprocket 73, the roller chain 74, and the connecting shaft 75, the tapes 10 of the tape group 12 can be evenly pulled out, and the tension of each tape can be kept constant. Can be maintained at

With these, the entire feeding operation of the tape group 12 can be accurately and surely performed, and the tape group 12 pulled out on the tape group 11 can be carried out.
Can be in a predetermined uniform state.

Therefore, according to the present embodiment, the automation of each process can be performed easily and reliably, and no manual pulling out work or adjustment is required for manufacturing the latticed web 13, and the work efficiency is improved by eliminating the manual work. And the product accuracy can be greatly improved.
