Description

  The present invention relates to a flexible work winding method and a winding apparatus that can be suitably used when a flexible work such as a fabric product is folded in a compact manner.

When wrapping a flexible workpiece such as a fabric product in a compact manner, one end of the flexible workpiece placed in a stretched state on a work table by a winding core comprising a pair of two parallel bars. An apparatus is known in which a flexible work is wound around a winding part by rotating the winding core (see Patent Document 1 and the like).
In this apparatus, the winding core is rotated on the spot, and the flexible work is moved toward the winding core side while sliding on the work table as the winding progresses.
No. 1-265565 gazette

  In the above-described conventionally known apparatus, the winding core rotates on the spot, and the flexible work is brought close to the winding core. Sliding friction with respect to the table will occur. If the flexible workpiece is a fabric knitted with delicate fibers (for example, pantyhose), these tensile action and sliding friction may cause damage to the fabric.

In addition, in order to wrap a flexible work wound around a core in the next process, it is necessary to move a long distance to deliver the flexible work extracted from the core to the next process. It affected the operation efficiency of the entire line and sometimes caused a bottleneck in speeding up the cycle time.
The present invention has been made in view of the above circumstances, and in making a flexible work into a compact folded shape for packaging or the like, a flexible work that can be quickly executed without damaging the flexible work. An object is to provide a winding method and a winding device.

In order to achieve the above object, the present invention has taken the following measures.
That is, in the method for retracting a flexible work according to the present invention, the aspect ratio of the cross-sectional shape is flattened by repeatedly folding the flexible work held in the stretched state from one end side along the stretched direction. While winding on the core, move the core along the direction of stretching of the flexible work so that it is substantially synchronized with the winding speed with respect to the core, and after the flexible work has been wound, The flexible work is taken out in the extending direction of the moving direction and stored in the packaging member.

Since the winding core is moved while winding the flexible work around the winding core in this way, the winding core is inevitably moved by a considerable distance when the winding is completed. The work can be quickly transferred to the next process for storing the work in the packaging member. That is, the operation efficiency is improved accordingly.
In addition, since the winding speed and the moving speed when winding the flexible workpiece on the winding core are substantially synchronized, even if the flexible workpiece is wound on the work table, the flexible workpiece and the work table There is no relative movement between Therefore, the tensile action and the sliding friction affected by the self-load do not occur with respect to the flexible work, and the flexible work is not likely to be damaged.

Even after the winding of the flexible work is completed, it is preferable that the flexible work and the winding core reach each other separation position while continuing the winding operation and movement of the winding core.
In this way, as a continuous operation of the winding operation of the flexible workpiece, the wound flexible workpiece can be smoothly transferred to the delivery operation to the next process, and the operation efficiency can be further improved. Moreover, since there is no possibility that the flexible work wound around the winding core will loosen the wound state, there is also an advantage that it can be securely stored in the packaging member in the next step.

In addition, when the winding core is configured to have two pairs of forks, the flexible work winding method according to the present invention is embodied as follows.
That is, the crotch part of a pair of forks is inserted near one end of the flexible work held in the stretched state so that the different forks are distributed on both sides of the flexible work. Set the fulcrum shaft around the other fork and move the other fork around, stop the fork moving around when the fork moving in contact with the flexible workpiece, and then move this fork around. The stopped fork is set as a fulcrum shaft, and the fork that has been used as a fulcrum shaft is moved in the same direction as the above-mentioned circumferential movement. At that stage, the fork is stopped from moving in the circumference, and the alternate circumferential movement by these two forks is repeated as many times as necessary so that the flexible work is moved along the direction of stretching. Wrapped Ri, taken out flexible workpiece that is a wound state thereafter.

  Here, the fork whose center is between both forks and whose rotation axis is provided on an extension line that is parallel to and horizontal with both forks and whose trajectory of the fork that moves in the circumference is a fulcrum shaft The rotation axis is raised during the circumferential movement of the first half of the circumference in the upper half circumference area, and during the circumferential movement of the second quarter of the circumference By lowering the rotating shaft, the fork serving as the fulcrum shaft can be held at a constant height.

Also, the movement time required for the fork to move the circumference moves the pitch circle diameter of the circumferential movement trajectory, and the rotation axis that rotates both forks moves the same distance along the extension direction of the flexible workpiece By making the times to coincide with each other, the fork on the fulcrum shaft can be held in a stationary state relative to the flexible workpiece.
The flexible work is set to the forward position indicated by each fork while the flexible work extending direction is perpendicular to the fork longitudinal direction of the pair of forks. It is possible to carry in the winding work position by moving it toward the end, and then start a series of flexible work winding operations by both forks.

By doing so, the flexible workpiece can be set easily and quickly, and automatic operation can also be handled.
On the other hand, the retractor for a flexible work according to the present invention includes a work table for supporting a flexible work in a stretched state, and the vicinity of the work table along the stretch direction of the flexible work supported by the work table. A slide mechanism having a movable base that can be moved back and forth, a lift mechanism having a lift base that can be moved up and down with respect to the movable base of the slide mechanism, and a lift base of the lift mechanism A fork support that couples a pair of forks and a pair of forks on a work table in a cantilever projecting state and with a parallel spacing that allows a flexible workpiece to be sandwiched between them. And a core rotation drive unit that rotates the core around a rotation axis that is connected to the fork support unit in a direction opposite to the protruding direction of each fork. To have.

By setting it as such a structure, the winding method of the flexible workpiece | work concerning this invention can be implemented, and a concise structure can be implement | achieved.
In the fork support portion of the take-up mechanism, the rotation shaft may be provided on an extension line that is at the center position between both forks and is parallel to and parallel to both forks.
In this way, the structure can be simplified. In addition, in the fork support portion, in addition to the above-described structure in which the rotation shaft is located at the center position between the two forks, it is also possible to adopt a structure that can move so as to be the same fulcrum shaft as each fork. In this case, the lifting mechanism can be omitted, but this is merely an example as an embodiment.

  With the flexible work winding method and the winding apparatus according to the present invention, the flexible work can be quickly performed without damaging the flexible work in making the flexible work into a compact folded shape for packaging or the like.

As shown in FIGS. 1 to 4, the retracting device 1 includes a work table 2, a slide mechanism 3, an elevating mechanism 4, and a winding mechanism 5.

The work table 2 supports the flexible work W in a stretched state, and the flexible work W is supplied by manual operation by an operator or automatic conveyance by a conveyor device or the like.
The slide mechanism 3 has a moving base 10 that reciprocates in the vicinity of the work table 2, and the moving base 10 is provided along the extending direction of the flexible work W supported by the work table 2. It is slidably held in the horizontal direction with respect to the guide rail 11 and is driven by a linear motion drive means 12 such as a winding drive means or a rodless cylinder. For these reasons, the movable base 10 can move along the direction in which the flexible workpiece W extends.

  In this embodiment, the moving base 10 reciprocates below one side of the work table 2, and the linear motion driving means 12 drives an endless belt 12a such as a timing belt, a V belt, a van cord belt, etc., by a motor 12b. The belt mechanism is configured such that the guide rail 11 is fixed on the installation frame 13 of the linear motion driving means 12, and the movable base 10 is mounted on the guide rail 11 via the slide unit 14.

The winding mechanism 5 is provided with respect to the lifting base 18 of the lifting mechanism 4 and is lifted and lowered together with the lifting base 18. The winding mechanism 5 includes a core 25 and a core rotation drive unit 26.

The winding core 25 has a pair of forks 30 and a fork support portion 31 that couples the forks 30 together. The fork support portion 31 is provided with a rotating shaft 32 that is coupled in the direction opposite to the protruding direction of each fork 30.
The fork support portion 31 is configured to hold both forks 30 in a cantilevered state toward the work table 2, and allows the forks 30 to be parallel to each other so that the parallel interval can be inserted between the flexible workpieces W. The dimensions are set to various dimensions. The rotating shaft 32 is located at the center position between the forks 30 and on an extension line that is parallel to and parallel to the forks 30.

  In this embodiment, the fork 30 is a round bar, and its tip is chamfered in a hemispherical shape so that the flexible work W can be prevented from being damaged without being caught when contacting the flexible work W. It is. Further, the smoothness of the surface is enhanced by performing plating treatment, polishing or the like over the entire length as well as the tip of the fork 30, and the effect of preventing damage to the flexible workpiece W is further enhanced.

The straight rod portion may be the fork 30 and the bent rod portion connecting the crotch may be the fork support portion 31). Further, the fork 30 may be a square bar material or a strip-like material other than the round bar material.

The core rotation drive unit 26 is a place where the core 25 is rotated about the rotation axis 32. The rotating shaft 32 is held horizontally, and therefore the two forks 30 move around the rotating shaft 32 while maintaining the horizontal state.

However, these may be reversed (the guide rail 43 is on the upper substrate 42 side and the slide unit 44 is on the lower substrate 41 side). Further, for driving to move the lower substrate 41 and the upper substrate 42 relative to each other, a method of driving a belt mechanism, a meshing mechanism of a rack and a pinion, or the like, a method of driving by a fluid pressure cylinder, or the like may be adopted. it can.

Next, a method for retracting the flexible workpiece W according to the present invention will be described with reference to FIGS. 5 and 6 on the basis of the operation status of the retractor 1 having the above-described configuration.
First, as shown in FIGS. 1 and 5A, the flexible work W is set in a stretched state on the work table 2 (set). At this time, the flexible work W is positioned at the tip position indicated by each fork 30 in the core 25. Further, the longitudinal relationship of the pair of forks 30 and the extending direction of the flexible work W are arranged so as to be orthogonal to the winding core 25.

The flexible work W is moved toward the core 25 in the stretched state, and is inserted into the crotch portions of both forks 30 as shown in FIG. Another fork 30 is arranged and distributed. This state is a winding work position for the flexible work W and the core 25.
Next, as shown in FIGS. 5B to 5C, one fork 30 (the fork 30 that is visible above the flexible work W) is set as a fulcrum shaft, and the other fork 30 is set around this fork 30. Move around the circumference. As shown in FIG. 6A, when the circumferentially moving fork 30 comes into contact with the flexible work W, the circumferential movement of the fork 30 is stopped.

Here, using one fork 30 as a fulcrum shaft means that the fork 30 is rotated but not moved up and down or horizontally. That is, the relative movement does not occur between the fork 30 serving as the fulcrum shaft and the flexible work W.
Next, as shown in FIGS. 6A to 6C, the fork 30 whose circumferential movement has been stopped in the above description is set as a fulcrum shaft. In addition, the fork 30 that has been used as a fulcrum shaft is moved in the same direction as the circumferential movement, and the circumferentially moving fork 30 comes into contact with the flexible workpiece W (strictly, In this stage, since the fork 30 has a part of the flexible work W wound around it, the circumferential movement of the fork 30 is stopped.

  At this stage, as shown in FIG. 6C, one turn of the flexible work W is wound around the core 25 (two forks 30). That is, the flexible workpiece W held in the stretched state is folded twice from the one end side along the stretch direction, and the folded flexible workpiece W has a cross-sectional aspect ratio. Is wound around a flat core 25 to form a flat folded shape.

Further, since the relative movement between the fork 30 serving as the fulcrum shaft and the flexible work W does not occur, the winding core 25 moves along the extending direction of the flexible work W substantially in synchronization with the winding speed. It has become a state.
Thereafter, the flexible work W can be wound around the core 25 along its extending direction by repeating the alternate circumferential movement of the core 25 by the two forks 30 as many times as necessary.

Finally, after all the flexible workpieces W have been wound, the flexible workpiece W and the core 25 that have been wound are separated, and the flexible workpiece W is taken out and stored in a packaging member. do it.
As described above, the winding core 25 moves along the extending direction of the flexible workpiece W while being substantially synchronized with the winding speed of the flexible workpiece W, so that the winding core 25 has a considerable distance when the winding is completed. By moving the flexible workpiece W in the direction of extension of the moving direction, the flexible workpiece W can be quickly transferred to the next process, and the operating efficiency of the retractor 1 can be increased accordingly. It will be excellent.

As described above, in the core 25, one fork 30 is used as a fulcrum shaft (rotates but does not move up and down or horizontally), and the other fork 30 is moved around the circumference. The operation control as shown in the time chart of FIG. 7 is employed.
That is, it is assumed that at the standby time, the core 25 is in a standby state so that the two forks 30 are in a vertical positional relationship with each other, and the crotch between both forks 30 passes through in the horizontal direction.

In this standby state, the forward / backward movement mechanism 40 is advanced in advance, and the flexible workpiece W is already inserted into the crotch portions of both forks 30. The flexible work W is positioned at the center position between the two forks 30 (the position of the rotating shaft 32).
Now, in this standby state, the fork 30 in the upper position (shown by ●) is called “fork A”, and the fork 30 in the lower position (shown by ○) is called “fork B”. Say.

In the time chart of FIG. 7, the description will be made with the portion indicated by “first rotation” on the horizontal axis at the top. First, the winding mechanism 5 rotates the core 25 by 90 ° from the standby state to the START time. As a result, the forks A and B are arranged in a substantially horizontal state, side by side, and the fork A contacts the upper surface of the flexible work W and the fork B contacts the lower surface of the flexible work W.
Next, when the winding mechanism 5 rotates the winding core 25 by 90 ° from the START position to the 90 ° position, the lifting mechanism 4 raises the rotating shaft 32 of the winding mechanism 5 and the slide mechanism 3 moves. Start. The moving speed of the winding core 25 by the slide mechanism 3 at this time is substantially synchronized with the winding speed when the flexible work W is wound on the winding core 25.

  That is, if the core 25 rotates on the spot, the fork A moves downward to the position below the rotating shaft 32 and moves backward from the moving direction. Since the rotary shaft 32 is raised, the fluctuation in height is canceled, and the rotary shaft 32 is moved, so that the horizontal positional fluctuation is canceled. As a result, an absolute positional fluctuation occurs in the fork A. Absent. Therefore, the fork A does not move at all with respect to the flexible work W, and the contact state is maintained.

  On the other hand, in the case of the fork B, as it tries to move to the position directly above the rotating shaft 32 and to move forward from the horizontal position and move forward in the moving direction, this is accompanied by the ascending and moving of the rotating shaft 32 as it is. Will be amplified. Accordingly, the fork B moves to a position directly above the fork A and rises above the flexible work W, and the forks A and B are vertically aligned with each other (the fork A is below and the fork B is opposite to the standby time). Is above).

Next, when the winding mechanism 5 rotates the winding core 25 by 90 ° from the 90 ° position to the 180 ° position, the lifting mechanism 4 lowers the rotating shaft 32 of the winding mechanism 5. Note that the moving state of the slide mechanism 3 is maintained in a constant state.
In the rotation of the winding core 25 at this time, the fork A moves up and backwards in an attempt to move to the right lateral position on the rear side in the moving direction of the rotating shaft 32, but the height varies with the lowering of the rotating shaft 32. Are offset and horizontal positional fluctuations are canceled as the rotary shaft 32 moves, and absolute positional fluctuations do not occur in the same manner as described above. Therefore, the fork A still has no relative movement with the flexible work W, and the contact state is further maintained.

On the other hand, the fork B moves downward and advances in an attempt to move to the lateral position on the side of the moving direction of the rotating shaft 32, and this is amplified as the rotating shaft 32 moves up and down. . Accordingly, the fork B moves to a position just beside the fork A and comes into contact with the upper surface of the flexible work W, so that the forks A and B are in a substantially horizontal state in which they are arranged side by side.
As is apparent from the above description, when the winding core 25 is rotated by 180 °, the fork A has neither absolute position fluctuation nor relative position fluctuation with respect to the flexible work W, and the fork A does not change. The fork B moves circumferentially in the upper half circumference region around it.

  Here, the rotary shaft 32 is raised during the circumferential movement of the former half of the fork B in the upper half circumferential region, and the rotational shaft 32 is moved during the circumferential movement of the latter quarter of the circumference. In this process, as shown in FIG. 9, the fork B travels the pitch circle diameter P of the circumferential movement trajectory, and the rotation axis 32 extends the flexible workpiece W in the extending direction. And the time for moving by the same distance S (S = P) along the same distance. This means that “the moving speed of the core 25 by the slide mechanism 3 is substantially synchronized with the winding speed when the flexible work W is wound on the core 25”.

  In the same manner as the 180 ° rotation of the winding core 25 described above, the upper half-circumference around the fork B while preventing the absolute position fluctuation of the fork B and the relative position relative to the flexible work W from occurring. By moving the fork A in the region (rotating the core 25 in the range of 180 ° to 360 °), the flexible work W for one round is wound around the core 25.

  The rotary shaft 32 is raised during the circumferential movement of the first half of the fork A in the upper half circumference region, and the rotary shaft 32 is lowered during the circumferential movement of the second quarter of the circumference; The movement time required for the fork A to move the pitch circle diameter P of the circumferential movement locus, and the time for moving the rotating shaft 32 by the same distance S (S = P) along the extending direction of the flexible work W Are the same as those of the fork B described above.

  In this way, the winding core 25 is appropriately rotated so that the entire extending direction of the flexible work W is wound around the winding core 25. As a result, the flexible work W is wound around the core 25 without moving on the work table 2, so that the tensile action and sliding friction affected by the self-load on the flexible work W are not affected. It does not occur, and there is no possibility that the flexible work W is damaged.

  Note that it is preferable that the flexible work W and the core 25 reach the separation positions from each other while the winding operation and movement of the core 25 are continued even after the winding of the flexible work W is completed. Thereby, as the continuous operation of the winding operation of the flexible workpiece W, the wound flexible workpiece W can be smoothly transferred to the delivery operation to the next process, and the operation efficiency can be further improved. Moreover, since there is no possibility that the flexible work W wound around the winding core 25 loosens the winding state, there is an advantage that the packaging member can be surely accommodated in the next step.

As shown in FIG. 8, after the flexible work W has reached the separation position from the winding core 25 and the longitudinal movement mechanism 40 is moved backward to separate the winding core 25 from the flexible work W, the slide mechanism 3 is removed. The reverse movement by is started to return to the standby position. During this return, the lifting mechanism 4 and the winding mechanism 5 are also returned.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.

  The work table 2 can be configured by a belt conveyor that conveys the flexible work W toward a position where the core 25 reciprocates. In this case, the belt surface may be provided with a recess for allowing one fork 30 of the winding core 25 to be inserted in the axial direction between the upper surface and the lower surface of the flexible work W. This recess may be provided endlessly along the direction in which the belt belt is formed endlessly. Such a recess can also be formed by fitting two band cord belts parallel to each other at a predetermined interval with respect to a belt belt having a flat belt surface.
