Description

  In the present invention, an adhesive may be applied to a flexible member, for example, a stretchable fabric (planar member) constituting clothing, and the tube shape (hereinafter, the tube shape may be described as an annular shape). In particular, the adhesive member is applied to a planar member (for example, a planar cloth) and then continuously adhered to the tubular member to produce a tubular member (for example, a tubular cloth). The present invention relates to a cylindrical member manufacturing apparatus that can automatically realize this. In addition, the manufacturing object of the manufacturing apparatus which concerns on this invention is not limited to a stretchable fabric.

  In recent years, in the field of clothing (especially underwear), there has been proposed a method and an apparatus for adhering fabrics of respective parts constituting an underwear to each other with an adhesive, rather than sewing (sewing) with needles and sewing threads. By bonding the fabrics with an adhesive, it is possible to eliminate the unevenness of the sewing thread formed on the surface of the fabric by sewing, and to make the front and back surfaces of the underwear smooth. Thus, by making the adhesive part thin, it is possible to manufacture an underwear such as an undershirt that has a good touch and does not resonate with the outer.

In such an apparatus for adhering the cloth, the adhesive is usually heated to be liquid and discharged from a nozzle. The dough is arranged in the vicinity of the nozzle and sequentially transferred. As a result, an adhesive is attached to the cloth, and another cloth is then superimposed on the cloth with the adhesive attached, and the cloths are bonded together by pressure bonding.
An example of such a fabric bonding apparatus is disclosed in Japanese Patent Publication No. 11-512129 (Patent Document 1) and Japanese Patent Publication No. 2003-528227 (Patent Document 2).

  In the bonding method disclosed in Patent Document 1, two pieces of cloth made of a thin and flexible other material such as a woven fabric or leather or a synthetic sheet used for manufacturing clothes, lining articles, furniture and the like are used. A method of adhering with an additional material, wherein an adhesive deposit is formed on at least one piece of cloth along an adhering area provided on at least one of the cloth pieces, and then the adhering area of the two pieces of cloth The adhesive portions are formed by pressing each other together. In this bonding method, heating is performed only from one cloth piece side when pressing.

  The bonding apparatus disclosed in Patent Document 2 is an apparatus for bonding two fibers or similar products with a hot melt layer, and is a means for advancing the hot melt layer together with the fibers. Means for carrying one fiber and a very thin hot melt layer together in a cooled state, and heating to act on the hot melt layer and plasticize the hot melt layer until the surface contacts the first fiber Means and means for carrying the second fiber and pressing the two fibers until the plasticized hot melt layer contacts the first fiber. In this bonding apparatus, the hot melt layer is plasticized by heating means before the first fiber and the second fiber come into contact with each other.

  By the way, in an upper body garment (for example, an undershirt), it is a stretch knitted fabric having a circularly knitted body part and left and right sleeve parts, and the body part and the sleeve part are knitted separately. The armhole of the sleeve is sewn in an annular shape with the shoulder around the arm. Japanese Patent Laid-Open No. 2003-326602 (Patent Document 3) discloses a method of sewing a seam portion (for example, a sleeve portion that is a seam portion between a waistline portion and a sleeve portion) when manufacturing a wet suit or the like, although it is not an undershirt. Further, an apparatus for preventing or reinforcing water leakage by welding a seal tape to a seam portion is disclosed, and it is also disclosed that a seam portion is welded directly without sewing the seam portion.

The welding and bonding apparatus disclosed in Patent Document 3 is a welding and bonding apparatus in which a sheet-shaped material is fed between a pair of rollers, and the sheet-shaped material is heated and bonded by a heating unit while pressing with the rollers. The roller includes a common roller and a first roller and a second roller that are in pressure contact with the common roller, and the first roller is provided at the tip of a cylinder portion disposed in a direction orthogonal to the material traveling direction. The second roller is provided at the tip of the arm portion disposed along the material traveling direction, and the cylinder portion and the arm portion are rotated by a driving source so that the first and second rollers are the common roller. And the heating means is a horn that applies ultrasonic vibration to a material wound around the first or second roller pressed against the common roller. To. According to this welding and joining apparatus, even in the case of welding joining of an annular part of a material such as an armhole part or welding joining of a part along the length direction of a tubular material such as a sleeve part or a crotch part, By alternately switching the arm portion to the operating position, it is possible to continuously weld and bond with one device. Therefore, it is not necessary to divide the work into separate processes using a dedicated machine as in the prior art, and the equipment cost and manufacturing cost can be greatly reduced.

Japanese National Patent Publication No. 11-512129 Special table 2003-528227 gazette JP 2003-326602 A

  In these bonding techniques disclosed in Patent Document 1 and Patent Document 2, the adhesive is applied over almost the entire width of the bonding region along the conveying direction of the cloth or web to be bonded. For this reason, the adhesive is applied to almost the entire area of the bonding region, and the fabrics and the like are bonded to each other. Moreover, although it does not show a prior art document concretely, it is also well-known that the heat bonding adhesive tape is supplied to the cloth and the cloths are bonded to each other.

  However, in such a case, the adhesive is applied in a sheet form and bonded to almost the entire area of the bonding region. For this reason, since the adhesion region is planar, high adhesion strength can be secured between the adhesion surfaces of the fabric, but the stretchability of the fabric is hindered, and the stretchability inherent to the fabric is impaired. . Clothing such as underwear composed of the fabric thus bonded does not have elasticity even if the bonded portion has sufficient strength.

  That is, both of these Patent Documents 1 and 2 only disclose a bonding technique for bonding two sheet-like cloth pieces in a planar and entire manner, and do not disclose a technique for bonding them in an annular shape. In adhering the fabric in a ring shape, it is necessary to match the adhesion start point and the adhesion end point. However, matching the start point and the end point in this manner is an important issue due to the stretchability of the fabric. Adhesion technology that adheres two-dimensionally and entirely does not solve such problems. On the other hand, although patent document 3 discloses welding a seam part directly, without sewing the armhole part which is a seam part of a waist part and a sleeve part, the detail of the technique welded annularly without sewing Is not disclosed at all.

  Hereinafter, a cylindrical member manufacturing apparatus (hereinafter sometimes simply referred to as a manufacturing apparatus) 1000 according to an embodiment of the present invention will be described with reference to the drawings. The cylindrical member manufacturing apparatus 1000 is an apparatus that bonds a planar member, which is an example of a flexible member, into a tubular shape, and more specifically, a planar member having flexibility. An example of an apparatus for producing a cylindrical fabric for sleeves from a flat fabric for clothing, for example, applying a hot-melt (synonymous with thermoplastic) adhesive in a desired adhesive pattern, Adhere in a cylindrical shape. Here, the processing target of the cylindrical member manufacturing apparatus according to the present invention is not limited to the planar member, and may not be planar, and the manufacturing target is not limited to the cylindrical fabric of the sleeve portion. It does not have to be a sleeve.

  Further, the planar member having flexibility is not limited to the fabric having such stretchability, and for example, a planar material (sheet-like) and more preferably a stretchable material (member, material). ), And stretchable fabrics, stretchable materials such as stretch materials, rubber materials, polyurethane films, and composites composed of these materials. Further, since the planar member itself is formed of two materials, it may be used not only when the same material is bonded but also when different materials are bonded. That is, the object to be manufactured in the present invention is not limited to a cloth or the like, and may be a planar member having flexibility so that it can be formed into a cylindrical shape, and preferably has elasticity.

  Although details will be described later as operations, in the following, it is assumed that an object to be bonded by the manufacturing apparatus 1000 according to the present embodiment is a cloth forming an undergarment. For this reason, the planar member is a planar fabric, and the tubular member is a tubular fabric. That is, the manufacturing apparatus 1000 is preferably used when a sleeve portion of an undergarment that is a cylindrical fabric is manufactured by adhering a flat fabric suitably used for such an undergarment in a cylindrical shape. Furthermore, this underwear is a female undershirt that can be worn under an outer garment (for example, a thin knit), feels good, and does not resonate with the outer.

  Here, a preferable adhesive is appropriately selected depending on the material of the fabric, the adhesive strength, the adhesion site, and the like, and the heat melting temperature of the adhesive follows the selection. In some cases, an adhesive having a heat melting temperature close to room temperature may be selected.

[overall structure]
FIG. 1 is a perspective view showing the entire tubular member manufacturing apparatus 1000 according to the present embodiment, FIG. 2 is a front view showing the entire tubular member manufacturing apparatus 1000, and FIG. 3 is a partially enlarged view of FIG. Respectively.

  As shown in these drawings, the tubular member manufacturing apparatus 1000 as a whole has a coating unit 1100 provided near the center of the manufacturing apparatus 1000, a right unit 1000R provided on the right side, and a left side facing. The left unit 1000L provided in the. Note that “toward” means that when an operator operates the manufacturing apparatus 1000 (particularly, when a flat fabric is set in or removed from the manufacturing apparatus 1000), the work is performed. It means the direction based on the position where the person stands.

  In the manufacturing apparatus 1000, the coating unit 1100 is commonly used by the right unit 1000R and the left unit 1000L. That is, the manufacturing apparatus 1000 is largely configured by a right unit 1000R, a left unit 1000L, and a coating unit 1100 shared by the right unit 1000R and the left unit 1000L. The right unit 1000R and the left unit 1000L are It is installed symmetrically. In order to provide such a symmetric structure, it is basic to attach “R” indicating the right unit or “L” indicating the left unit to each component constituting the right unit 1000R and the left unit 1000L. However, these symbols without “R” and “L” indicate either the right unit or the left unit.

  The right unit 1000R and the left unit 1000L each include a first hollow prism (conveying prism) 1010R and 1010L that holds the fabric including the bonding area, and a second hollow prism (inverted prism) that holds the cloth including the bonded region. ) 1210R, 1210L, reversing units 1200R, 1200L for reversing the second hollow rectangular column by approximately 180 °, press units 1400R, 1400L for heating and pressure-bonding (heating set) the bonding area, and press unit 1400R from the position of the coating unit 1100 Conveying units 1300R and 1300L for conveying the cloth to a position of 1400L.

  In the manufacturing apparatus 1000, after the operator sets the cloth and presses the processing start button (start button), the manufacturing apparatus 1000 automatically applies the adhesive to the bonding area and applies the adhesive. When the process is over, one side of the fabric is automatically reversed and temporarily bonded by bringing the bonding area and the bonded area into contact with each other, and the temporary bonding state is automatically conveyed to the press unit to automatically bond the bonding area. Set the heat. As described above, the manufacturing apparatus 1000 continuously and automatically executes the process of manufacturing the cylindrical fabric from the planar fabric, which is a process other than the setting operation of the planar fabric and the removal operation of the cylindrical fabric. For this reason, when the operator sets the planar fabric in the right unit 1000R (takes out the tubular fabric if the processed cylindrical fabric is in the right unit 1000R) and presses the processing start button (start button), the left Move to the unit 1000L, set the flat fabric on the left unit 1000L, and press the processing start button (start button). While the planar fabric is set in the left unit 1000L, the planar fabric is continuously and automatically processed in the right unit 1000R. When a flat fabric is set in the left unit 1000L and a processing start button (start button) is pressed, the operator moves to the right unit 1000R and takes out the processed cylindrical fabric from the right unit 1000R. Then, the next planar fabric is set in the right unit 1000R and a processing start button (start button) is pressed. In this way, the planar dough setting operation and the cylindrical dough taking out operation in one unit and the continuous and automatic processing by the manufacturing apparatus 1000 in the other unit are superposed on each other, thereby efficiently producing the planar dough. A cylindrical fabric can be produced from the fabric.

  However, the present invention is not limited to the cylindrical member manufacturing apparatus provided with such a symmetrical unit, and any coating unit 1100 provided with either the right unit 1000R or the left unit 1000L may be used. Absent. In the right unit 1000R and the left unit 1000L, the press units 1400R, 1400L and the transport units 1300R, 1300L are optional configurations.

[Each component configuration]
・ Coating unit 1100
The application unit 1100 includes an application head 1110 having a nozzle for applying an adhesive to the adhesion region of the first surface of the flat fabric sucked and held by the first hollow prism 1010. Here, to apply means to discharge toward the dough without contact with the dough, but is not limited to non-contact. In addition, the application head 1110 applies adhesive to the fabric in a repeated pattern. The repeated pattern is an adhesive pattern P shown in FIG. 12B described later or an adhesive dot pattern D shown in FIG. 13B. In order to form such an adhesive pattern on the held fabric, the coating unit 1100 includes a coating head driving single-axis robot 1140 that horizontally moves the coating head 1110 in the direction indicated by the arrow X in FIG. 3 and the coating head 1110.

Prepare.

  In this way, the application unit 1100 stores, for example, a necessary amount of adhesive in order to repeatedly apply a thermoplastic resin adhesive to the fabric from the application head 1110, and the adhesive heater controller 1170 allows the adhesive to be applied. From an adhesive storage unit having an adhesive heater whose temperature is maintained so that the temperature becomes a predetermined viscosity, the adhesive heated to a desired viscosity by a gear pump is sent to the application head 1110 and applied. An adhesive is applied from the head 1110 to the fabric. These adhesive storage unit, gear pump motor 1150, gear pump and application head 1110 are basically known ones. The control unit 1500 controls the amount of adhesive that is fed into the coating head 1110 in the coating unit 1100 (that is, the amount of adhesive discharged from the coating head 1110). For example, the rotational speed of the gear pump motor 1150 is changed by the control unit 1500 to control the amount of adhesive sent from the gear pump to the coating head 1110, so that the amount of adhesive applied from the coating head 1110 to the fabric is reduced. Be controlled.

The nozzle diameter of the coating head 1110 is determined by the type of fabric to be coated, the repetitive pattern (for example, the amplitude of the coating head 1110 by the crank motor 1160), the coating amount per unit area of the fabric, and the like.

)), Application start position (1110 (R1), 1110 (L1)), application end position (1110 (R2), 1110 (L2)), reversal standby position (1110 (R3), 1110 (L3)) Is controlled by the control unit 1500. That is, the movement of the coating head 1110 within the XY plane is controlled by the control unit 1500.

  The coating head 1110 is driven by a crank unit that is driven by a crank motor 1160 in the Z direction (arrow Z), and the coating head is driven in the X direction (arrow X (1) -arrow X (2)). The longitudinal direction of the fabric (longitudinal direction of the hollow prism) while being moved reciprocally at a desired amplitude in a direction different from the longitudinal direction of the fabric (longitudinal direction of the hollow prism) as moved by the axis robot 1140. A repetitive pattern is advanced toward, and a desired repetitive pattern is formed. That is, the movement of the coating head 1110 in the XZ plane is controlled by the control unit 1500.

  In this way, the reciprocating movement of the coating head 1110 in the Z direction by the crank unit and the movement of the coating head 1110 from the X (1) direction to the X (2) direction by the coating head driving single-axis robot 1140 are performed on the fabric in a repetitive pattern. Adhesive is applied. More specifically, the reciprocating speed of the coating head 1110 by the crank unit and the moving speed in the X direction by the coating head driving single-axis robot 1140 are related and controlled by the control unit 1500, and will be described later with reference to FIG. Or an adhesive dot pattern D shown in FIG. 13B is formed.

-Reversing unit As shown in FIG. 3, the reversing unit 1200 is a fabric holding means, which is arranged in parallel in the longitudinal direction, and is the first of two hollow prisms that are smaller in cross-sectional area than the cylindrical fabric. 2 hollow prisms (inverted prisms) 1210 are changed in a direction of about 180 ° arrow R (2). As a result of reversing the second hollow rectangular column (reversing rectangular column) 1210 in the direction of arrow R (2) by approximately 180 °, the upper surface (second surface holding surface) of the second hollow rectangular column (reversing rectangular column) 1210 Is brought into contact with the upper surface (first surface holding surface) of the first hollow rectangular column (conveying rectangular column) 1010.

  The reversing unit 1200 reverses the second hollow rectangular column (reversing rectangular column) 1210 and the second hollow rectangular column (reversing rectangular column) 1210 in the direction of arrow R (1) -R (2) by approximately 180 °. The fabric reversing rotary actuator 1220 is configured to be controlled by the control unit 1500 so that the fabric reversing rotary actuator 1220 is normally reversed from the arrow R (1) direction to the R (2) direction and from the arrow R (2) direction. Reverse inversion in the indicated R (1) direction is controlled.

In addition to the second hollow prism (inverted prism) 1210, on the upper surface of the first hollow prism (conveying prism) 1010, an adhesive region (first hollow prism (conveying prism) 1010) and an adherend region (second A suction hole is provided in a portion corresponding to the hollow prism (inverted prism) 1210).
More specifically, a large number of suction holes are provided on the upper surface of the first hollow rectangular column (conveying rectangular column) 1010 and the upper surface of the second hollow rectangular column (reversing rectangular column) 1210, and the bonding region is formed by the cloth to be processed. Since the size and position, and the size and position of the adherend region are different, a thin metal plate that is open only in a portion of the adherence region and the adherend region is used as the upper surface of the first hollow prism (conveyance prism) 1010 and the second metal plate. The hollow prism (inverted prism) 1210 is attached to the upper surface of the hollow prism (inverted prism) (for example, removable by magnetic force). In this case, both the positioning of the thin metal plate and the upper surface of the first hollow prism (conveying prism) 1010 and the positioning of the thin metal plate and the upper surface of the second hollow prism (inverted prism) 1210 are both performed. is important. For this reason, a protrusion for positioning is provided on the upper surface of the hollow prism, and a thin metal plate is brought into contact with the protrusion so that a suction hole (suction hole group) of a correct size is opened at a correct position. ing.

As shown in FIG. 4, for example, a metal plate corresponding to a long sleeve (long sleeve) is attached to the right unit 1000R, and a metal plate corresponding to a short sleeve (short sleeve) is attached to the left unit 1000L. ing. In the right unit 1000R, one suction hole group 1230R corresponding to the position of the bonding region is formed on the upper surface of the first hollow rectangular column (conveying rectangular column) 1010R, and the upper surface of the second hollow rectangular column (reversing rectangular column) 1020R is bonded. One suction hole group 1240R that matches the position of the region is opened. Further, in the left unit 1000L, on the upper surface of the first hollow rectangular column (conveying rectangular column) 1010L, four suction hole groups 1230L aligned with the position of the adhesive region are provided, and on the upper surface of the second hollow rectangular column (reversing rectangular column) 1020R. Four suction hole groups 1240L corresponding to the position of the adherend region are opened. In the right unit 1000R, one long sleeve cylindrical fabric can be manufactured in one process, and in the left unit 1000L, four short sleeve cylindrical fabrics can be manufactured in one process.

A large number of suction holes arranged in this way are provided with a negative pressure pipe inside the hollow rectangular column, and a suction mechanism (for example, a suction mechanism using a blower 1510) connected to the negative pressure pipe causes air from the suction hole. By sucking the dough, the dough is sucked to hold the flat dough.
Conveying unit The conveying unit 1300 maintains a temporarily fixed state in which the bonding area of the first surface and the bonded area of the second surface are brought into contact with each other by the reversing unit 1200, thereby Transport to the position of the press unit 1400. The conveyance unit 1300 advances from the arrow Z (1) direction to the arrow Z (2) direction with respect to the first hollow rectangular column (conveying rectangular column) 1010 and is connected to the first hollow rectangular column (conveying rectangular column) 1010. A dough hand 1310 is provided for holding the dough between them and retreating from the arrow Z (2) direction to the arrow Z (1) direction to release the dough when such holding is unnecessary. The movement of the fabric hand 1310 in the Z direction is realized by a fabric hand holding air cylinder 1330 whose operation is controlled by the control unit 1500.

  The dough hand 1310 and the dough hand holding air cylinder 1330 are formed from the position of the coating unit 1100 or the reversing unit 1200 to the position of the press unit 1400 from the longitudinal direction (arrow X (3) direction to arrow X (4 ) Direction) is moved linearly so that the fabric that maintains the temporarily fixed state temporarily bonded by the contact between the bonded region of the first surface and the bonded region of the second surface is pressed. It is conveyed to the position of the unit 1400. The movement of the cloth hand 1310 and the cloth hand holding air cylinder 1330 in the X direction is realized by a cloth hand moving air cylinder 1320 whose operation is controlled by the control unit 1500.

  In this way, the transport unit 1300 sandwiches the temporarily fixed fabric between the first hollow rectangular column (conveying prism) 1010 and the fabric hand 1310 and conveys it linearly in the direction of the arrow X (4). The first hollow rectangular column (conveying rectangular column) 1010 includes a fixed (non-moving up and down) support portion provided at an end of the coating unit 1100 side (center side of the manufacturing apparatus 1000), and a first air cylinder. It can be supported by 1340 and / or the second air cylinder 1350. Here, in the both-end support system in which the first hollow rectangular column (conveying rectangular column) 1010 is supported by the support unit and the second air cylinder 1350, the length of the first hollow rectangular column (conveying rectangular column) 1010 in the longitudinal direction is long. Then, there is a problem that the horizontal state cannot be firmly maintained by bending.

In order to solve such a problem, it is conceivable that the first hollow rectangular column (conveying rectangular column) 1010 is supported at three points by the support portion, the first air cylinder 1340 and the second air cylinder 1350. In such three-point support, the movement operation of the temporarily fixed fabric in the X (4) direction by the conveyance unit 1300 is hindered by the support of the first hollow rectangular column (conveying rectangular column) 1010 by the first air cylinder 1340. Another problem that the removal of the cylindrical fabric from the manufacturing apparatus 1000 is hindered by the support of the first hollow rectangular column (conveying rectangular column) 1010 by the second air cylinder 1350. is there. In addition, since it is difficult to realize a horizontal state with three-point support and it is assumed that it is not preferable at the time of applying an adhesive, two-point support of the support portion and the first air cylinder 1340 or the support portion and the second air cylinder 1350 It is preferable to support by one of the two-point support. Furthermore, in the case of such two-point support, a problem that the movement operation of the temporarily fixed fabric in the X (4) direction by the conveyance unit 1300 is hindered, and the removal operation of the cylindrical fabric is hindered. To solve the problem, the mode is switched to one of a mode in which the support part and the first air cylinder 1340 are supported at two points and a mode in which the support part and the second air cylinder 1350 are supported at two points. Thus, it is preferable to support the first hollow rectangular column (conveying rectangular column) 1010 (however, three points are supported during hot pressing).

In the case of transporting the fabric temporarily fixed by the transport unit 1300, the first air cylinder 1340 is lowered while the second air cylinder 1350 is raised, and the first hollow rectangular column (conveying rectangular column) 1010 and the fabric hand 1310 is temporarily clamped and conveyed in the direction of arrow X (4).
When the cylindrical dough is taken out from the manufacturing apparatus 1000 after the processing in the manufacturing apparatus 1000 is completed, the second air cylinder 1350 is lowered while the first air cylinder 1340 is raised, and the first hollow rectangular column is removed. (Conveying prism) The cylindrical cloth wound around 1010 is extracted in the direction of arrow X (4).

  Thus, when the adhesive is applied to the fabric by the application unit 1100, the first air cylinder 1340 is in the raised state and the second air cylinder 1350 is in the lowered state. When the fabric in the state is conveyed in the direction indicated by arrow X (4), the first air cylinder 1340 is lowered and the second air cylinder 1350 is raised. As will be described in detail later, at the time of hot pressing, the first air cylinder 1340 and the second air cylinder 1350 are in a raised state, and after the hot pressing, only the second air cylinder 1350 is lowered to form a cylindrical fabric. During the extraction operation, the first air cylinder 1340 is raised and the second air cylinder 1350 is lowered. The state at the time of the extraction operation of the cylindrical fabric is the same as the state at the time of applying the adhesive to the fabric by the application unit 1100 which is the first process. The first air cylinder 1340 is lowered only at the time of transporting the temporarily-fixed fabric by the transport unit 1300, and other than that, the second air cylinder 1350 is lifted. As described above, the first air cylinder 1340 is lowered only when the first air cylinder 1340 is being lowered and during the hot press, and is otherwise lowered. The raising and lowering operations of the first air cylinder 1340 and the second air cylinder 1350 are controlled by the control unit 1500.

Press unit The press unit 1400 heat-presses the fabric temporarily transported by the transport unit 1300 and temporarily bonded by the contact between the bonding area of the first surface and the bonded area of the second surface. Then, the adhesive is heat-melted and finally bonded. This press unit 1400 is for a heater unit 1410 comprising a heater for heating an adhesion region and a holder for the heater, and a press heater for moving the heater unit 1410 in the direction of arrow Y (3) -arrow Y (4). An air cylinder 1420 is provided. The ascending operation (arrow Y (3) direction) and the descending operation (arrow Y (4) direction) of the press heater air cylinder 1420 are controlled by the control unit 1500. Further, the heater of the heater unit 1410 is maintained at a desired temperature by the press heater controller 1430, the press heater air cylinder 1420 is lowered, and the first hollow rectangular column (conveying rectangular column) 1010 and the heater unit 1410 The temporarily fixed dough is pinched and a desired amount of heat is given to the bonding area. The heat transfer surface of the heater unit 1410 is flat, and is in surface pressure contact with the upper surface of the first hollow rectangular column (conveying rectangular column) 1010. In addition to (or instead of) the heater unit 1410, a heater may be provided in the first hollow rectangular column (conveying rectangular column).

[Control block]
The manufacturing apparatus 1000 having such a configuration is controlled by the control unit 1500. For example, the control unit 1500 is mainly configured by a control panel 1502 provided with various instruments including a CPU 1600 described later. A display instrument 1520 and operation buttons 1540 are provided on the surface of the control panel 1502, and a display instrument 1530, operation buttons 1550, and a touch panel 1570 are provided separately from the panel surface of the control panel.

More specifically, the control unit 1500 will be described with reference to the control block diagram shown in FIG. In the control block diagram shown in FIG. 8, for example, a mode including a motor drive driver, a cylinder drive driver, and an output interface is shown. However, even if such a driver and / or interface is not actually provided, It suffices that the manufacturing apparatus 1000 is configured to realize a desired operation. As such a mode, a motor is not provided and the speed of the motor is controlled by a speed controller and the operation is controlled only by ON / OFF control from the CPU, or an air cylinder is adopted as the cylinder. For example, the operation may be controlled only by operating the solenoid valve.

  As shown in FIG. 8, the control unit 1500 receives various input signals according to programs and parameters (various speeds, etc.) stored in advance, performs arithmetic processing, and outputs various control signals (control signals) to various output devices. Between the touch panel 1570 and an input interface 1610 for receiving input signals from the operation buttons 1540 and 1550 and the various sensors 1560 connected to the CPU 1600, respectively. An input / output interface 1620 for transmitting and receiving signals, a cylinder drive driver 1630 for controlling various pneumatic devices such as the above-described air cylinder, and a single-axis robot for controlling the above-described coating head drive single-axis robot 1140 Drive driver 1640 and various motors described above The temperature of the motor driver 1650 for controlling, the output interface 1660 for transmitting an output signal to the blower 1510, the display driver 1670 for displaying the display devices 1520 and 1530, and the temperature of the above-described adhesive heater are set. The controller includes an adhesive heater controller 1170 to be controlled, a press heater controller 1430 for controlling the temperature of the heater of the heater unit 1410 described above, and a memory (program and parameters are not shown).

  An input interface 1610, an input / output interface 1620, a cylinder drive driver 1630, a single-axis robot drive driver 1640, a motor drive driver 1650, an output interface 1660, and a display driver 1670 are connected to the CPU 1600 through a bus or the like. The CPU 1600 is connected to an adhesive heater controller 1170 and a press heater controller 1430.

  The adhesive heater controller 1170 is connected to an adhesive heater and controls energization of the adhesive heater so as to maintain the adhesive in the adhesive storage unit at a desired temperature (viscosity depends on temperature). . The heater for the heater unit 1410 is connected to the press heater controller 1430, and energization to the heater of the heater unit 1410 is controlled so as to give a desired amount of heat to the bonding area of the fabric. Note that the adhesive heater controller 1170 and the press heater controller 1430 may be connected to the CPU 1600 or not connected thereto. When connected, for example, when the measured temperature of both heaters is within a predetermined range of the set temperature (when it is a desired temperature), an permission signal is sent to the adhesive heater controller 1170 and the press heater controller 1430. The CPU 1600 can be controlled to permit the operation of the manufacturing apparatus 1000 by receiving the permission signal. By controlling in this way, it is possible to avoid the operation of the manufacturing apparatus 1000 even when the temperature (viscosity) of the adhesive and the heater of the heater unit 1410 are not desired. In the following description, it is assumed that when a main switch (not shown) is turned on, the temperatures of both heaters are controlled to the set temperature by the temperature controller.

  The cylinder drive driver 1630 includes a coating head moving air cylinder 1120, a nozzle cap actuator 1130, a cloth reversing rotary actuator 1220 (1220R, 1220L), a cloth hand lateral moving air cylinder 1320 (1320R, 1320L), and a cloth hand holding air cylinder 1330 ( 1330R, 1330L), a first air cylinder (inside) 1340 (1340R, 1340L), a second air cylinder (outside) 1350 (1350R, 1350L), and a press heater air cylinder 1420 (1420R, 1420L). As described above, the cylinder driving driver 1630 is described as being connected to an air device such as an air cylinder to control the operation, but may be an electric cylinder instead of an air cylinder, for example. That is, as long as the mechanism required for the manufacturing apparatus 1000 can be realized, an air driving method, an electric driving method, or another driving method may be used.

The single-axis robot drive driver 1640 is connected to a coating head driving single-axis robot 1140 that moves the coating head 1110 in the X direction (arrow X (1) -arrow X (2)).
A gear pump motor 1150, a crank motor 1160, and a conveyor motor 1370 (1370R, 1370L) are connected to the motor drive driver 1650. In addition, as long as it is a mechanism which can implement | achieve the function calculated | required by this manufacturing apparatus 1000, it may not be a single axis | shaft robot and a motor but another drive unit.

  The CPU 1600 that has received the start command signal from the operation buttons 1540 and 1550 controls the manufacturing apparatus 1000 as follows, for example. In the description of this case, reference is mainly made to the timing chart of FIG. In the following, the operation in the left unit 1000L will be described. However, “L” may not be added to the code. Although not limited, the cylinders produced by the manufacturing apparatus 1000 are arranged in ascending order of n in S (n) (n = 0, 1, 2,...) Described in the timing chart shown in FIG. The manufacturing process of the dough is progressing.

  Before the operator presses the start command buttons (start button or the like) of the operation buttons 1540 and 1550, as shown in FIGS. 5 and 6A, the operator can set the first hollow rectangular column (conveying rectangular column) 1010. In the upper surface and the suction hole group portion provided on the upper surface of the second hollow prism (inverted prism) 1210, the flat fabric is set so as to be S-shaped in the cross-sectional direction (see FIG. 6A). ing. It is assumed that the cylindrical fabric manufactured by the manufacturing apparatus 1000 has been removed from the manufacturing apparatus 1000. Also, the air suction operation using the suction mechanism through the suction hole has already started when the flat fabric is set, and the fabric can be easily set including positioning. The suction operation is stopped when the dough hand 1310 is advanced in the direction indicated by the arrow Z (2).

  Upon receiving the start command, the CPU 1600 moves the coating head moving air cylinder 1120 and the coating head driving single-axis robot 1140 to the cylinder driving driver 1630 so as to move the coating head 1110 from the standby position 1110 (0) to the coating start position 1110 (L1). Control is performed via a single-axis robot drive driver 1640. At this time, the coating head 1110 moves in the direction indicated by arrow X (2) and in the direction indicated by arrow Y (2). In addition, the CPU 1600 that has received the start command moves the dough hand 1310 from the standby position (the position of the press unit 1400) to a standby position during application (for example, a position facing the second hollow rectangular column (reversing rectangular column) 1210). The fabric hand lateral movement air cylinder 1320 is controlled via a cylinder drive driver 1630. At this time, the dough hand 1310 moves in the direction indicated by the arrow X (3) while being retracted in the Z (1) direction.

  When the CPU 1600 detects that the application head 1110 has arrived at the application start position by an input signal from the sensor and detects that the fabric hand 1310 has arrived at the standby position at the time of application by an input signal from the sensor. The CPU 1600 outputs an application start command signal (nozzle cap opening, gear pump motor 1150 operation, crank motor 1160 operation) to the application unit 1100 so as to start application of the adhesive to the cloth by the application head 1110 and the application head. The coating head driving single-axis robot 1140 is controlled via the single-axis robot driving driver 1640 so as to move 1110 from the coating start position 1110 (L1) to the coating end position 1110 (L2). As a result, the nozzle cap actuator 1130 of the coating unit 1100 opens the nozzle cap, the gear pump motor 1150 and the crank motor 1160 start operating, and the coating head driving single-axis robot 1140 moves the coating head 1110 to the arrow X (2 ) Direction, and the coating head 1110 is reciprocated in the direction indicated by the arrow Z by the crank motor 1160. By the operations of the crank motor 1160 and the coating head driving single-axis robot 1140, a desired adhesion pattern (here, FIG. Adhesive is applied to the fabric with the adhesive pattern P) shown in (B).

When the CPU 1600 detects from the input signal from the sensor that the coating head 1110 has arrived at the coating end position 1110 (L2), the CPU 1600 ends the coating of the adhesive onto the cloth by the coating head 1110. A coating end command signal (nozzle cap closed, gear pump motor 1150 stopped, crank motor 1160 stopped) is output to the coating head 1110 and the coating head 1110 is moved from the coating end position 1110 (L2) to the reverse standby position 1110 (L3). The head moving air cylinder 1120 and the coating head driving single axis robot 1140 are controlled via a cylinder driving driver 1630 and a single axis robot driving driver 1640. At this time, the coating head 1110 moves in the direction indicated by the arrow X (2) and in the direction indicated by the arrow Y (1).

  When the CPU 1600 detects that the coating head 1110 has arrived at the reversal standby position 1110 (L3) based on the input signal from the sensor, the CPU 1600 moves the second hollow rectangular column (reversed rectangular column) 1210 in the direction of arrow R (2). The fabric reversing rotary actuator 1220 is controlled via the cylinder driving driver 1630 so as to be reversed by approximately 180 °. Then, for example, when a desired time elapses, the CPU 1600 drives the fabric reversing rotary actuator 1220 in a cylinder so that the second hollow prism (reversing prism) 1210 is reversed approximately 180 ° in the direction of arrow R (1). Control is performed via the driver 1630.

  When the CPU 1600 detects that the second hollow rectangular column (reversed rectangular column) 1210 is reversely inverted approximately 180 ° (returned to the original position) in the direction indicated by the arrow R (1) by the input signal from the sensor, the CPU 1600 The fabric hand holding air cylinder 1330 is controlled via the cylinder drive driver 1630 so that the fabric hand 1310 of the unit 1300 is advanced in the direction of arrow Z (2).

  Further, the CPU 1600 controls the conveyor motor 1370 via the motor drive driver 1650 so as to rotate the belt conveyor 1360 of the transport unit 1300 in the arrow C direction. If the temporary dough does not reach the belt conveyor 1360, there is no point in operating the belt conveyor 1360, so the belt conveyor 1360 may remain stopped. Further, when the temporarily fixed fabric does not reach the belt conveyor 1360, the temporarily fixed fabric receiving portion 1312 that moves in the direction of arrow X (3) -arrow X (4) together with the fabric hand 1310 below the fabric hand 1310. It is also preferable to provide (L-shaped angle).

  Further, the CPU 1600 raises the second air cylinder (outside) 1350 of the transport unit 1300 in the direction indicated by the arrow U via the cylinder drive driver 1630. When the CPU 1600 detects that the second air cylinder (outside) 1350 has been raised in the direction indicated by the arrow U by the input signal from the sensor, the CPU 1600 moves the first air cylinder (inside) 1340 of the transport unit 1300 to the cylinder drive driver. It is lowered in the direction of arrow D via 1630.

  At this timing, the CPU 1600 causes the coating head 1110 and the coating head to move the coating head 1110 from the reverse standby position 1110 (L3) to the standby position 1110 (0) for coating processing in the right unit 1000R. The drive single-axis robot 1140 may be controlled via the cylinder drive driver 1630 and the single-axis robot drive driver 1640. At this time, the coating head 1110 moves in the direction indicated by the arrow X (1) and in the direction indicated by the arrow Y (1). In this case, when the Y-axis coordinate of the reverse standby position 1110 (L3) and the Y-axis coordinate of the standby position 1110 (0) are the same, the coating head 1110 moves only in the direction of the arrow X (1). It will not move in the arrow Y direction.

  When the CPU 1600 detects that the first air cylinder (inside) 1340 has been lowered in the direction indicated by the arrow D by an input signal from the sensor, the CPU 1600 moves the fabric hand 1310 of the transport unit 1300 in the direction indicated by the arrow X (4). The fabric hand lateral movement air cylinder 1320 is controlled via the cylinder drive driver 1630 so as to be moved. Thereby, the dough in the temporarily fixed state is moved to the press unit 1400 side. At this time, the cloth temporarily fixed between the first hollow prism (conveyance prism) 1010 and the cloth hand 1310 is sandwiched and conveyed in the direction indicated by the arrow X (4). In this case, the friction coefficient between the fabric and the first hollow prism (conveying prism) 1010 is set to be smaller than the friction coefficient between the fabric and the fabric hand 1310 (for example, the arrow Z (2) of the fabric hand 1310). A rubber having a high coefficient of friction with the cloth is affixed on the surface in the direction), and the cloth frictionally engaged with the cloth hand 1310 is slid and conveyed on the surface of the first hollow rectangular column (conveying prism) 1010. .

When the CPU 1600 detects that the fabric hand 1310 has arrived at the main bonding position based on the input signal from the sensor, the CPU 1600 causes the conveyor motor 1370 to drive the motor drive driver 165 so as to stop the belt conveyor 1360 of the transport unit 1300.
Control through 0. Further, the CPU 1600 raises the first air cylinder (inner side) 1340 of the transport unit 1300 in the direction indicated by the arrow U via the cylinder drive driver 1630.

  When CPU 1600 detects that the first air cylinder (inside) 1340 has been raised in the direction indicated by the arrow U, the CPU 1600 moves the heater unit 1410 of the press unit 1400 in the direction indicated by the arrow Y (4). The press heater air cylinder 1420 is controlled via a cylinder drive driver 1630 so as to be lowered. As a result, the press heater air cylinder 1420 descends, and the temporarily fixed fabric is clamped by the first hollow rectangular column (conveying rectangular column) 1010 and the heater unit 1410. For example, the clamping time is managed by a timer. Thus, a desired amount of heat is applied to the bonded area. As a result, the adhesive is melted and the tubular fabric is permanently bonded. Only at the time of this hot pressing, the first air cylinder 1340 and the second air cylinder 1350 are in a raised state.

  When the CPU 1600 detects that the timer of the heat press has timed up, the CPU 1600 moves the press heater air cylinder 1420 to the cylinder drive driver so as to raise the heater unit 1410 of the press unit 1400 in the arrow Y (3) direction. Control via 1630. Further, the CPU 1600 controls the fabric hand holding air cylinder 1330 via the cylinder drive driver 1630 so that the fabric hand 1310 of the transport unit 1300 is retracted in the direction of arrow Z (1). Further, the CPU 1600 lowers the second air cylinder (outside) 1350 of the transport unit 1300 in the arrow D direction via the cylinder drive driver 1630.

In this state, the operator pulls out the cylindrical fabric that is permanently bonded by the manufacturing apparatus 1000 from the first hollow rectangular column (conveying rectangular column) 1010 toward the open end, and takes out the cylindrical fabric. At this time, the descending second air cylinder (outside) 1350 does not hinder the removal of the cylindrical fabric.
[Operation]
The operation of the manufacturing apparatus 1000 having the above structure will be described. In the description of the operation, a case where a cylindrical long sleeve portion is manufactured from a flat fabric before the sleeve portion of the undershirt is bonded to the body will be described as an example. In the description of this operation, first, an undershirt and an adhesive application pattern (adhesion pattern) will be described.

-Undershirt of operation | movement object The front view of the undershirt 10 is shown in FIG. As shown in FIG. 9, this undershirt 10 has a body part 11 that is circularly knitted and left and right sleeve parts 12. The body part 11 and the sleeve part 12 are stretch knitted fabrics knitted separately, and as will be described later, the body part 11 and the sleeve part 12 are joined at the armhole part by a bonding structure using an adhesive. Thus, the entire undershirt 10 is formed.

  Here, the expansion / contraction direction of the undershirt 10 will be described. The body part 11 is the direction in which the horizontal direction in FIG. 9 is the course direction (relative to the wale direction) and is easy to expand and contract (easily stretches along the waist), and the sleeve part 12 is along the circumference of the arm. The course direction is the course direction (relative to the wale direction), and is the direction that is more easily expanded and contracted (easily stretched around the arm). The course direction means the same direction as the knitting direction in the horizontal knitted fabric, and the wale direction means a direction orthogonal to the course direction.

In the case of using the course direction as described above, the armhole of the body part 11 is difficult to expand and contract with respect to the arm periphery direction of the sleeve part 12 (details will be described later, but there is a difference in elasticity in the armhole). The direction around the arm is easy to expand and contract. In this case, when joining the sleeve portion 12 to the body portion 11 by general sewing, it is necessary to sew the body portion 11 which is difficult to stretch to the sleeve portion 12 which is easy to stretch, so that the arm of the sleeve portion 12 can be sewn. The length in the rotation direction is designed to be shorter than the arm hole of the body part 11. On the other hand, in the case of a bonded structure using an adhesive, which will be described later, if the arm-around direction length of the sleeve portion 12 is designed to be shorter than the arm hole of the body portion 11 in this manner, The direction length may be insufficient. For this reason, the arm portion direction length of the sleeve portion 12 is the same as the arm hole of the body portion 11 or is designed to be longer than the arm hole of the body portion 11. In addition, when using a horizontal knitted fabric for an undershirt, it is as above-mentioned, but when using a warp knitted fabric, a course direction and a wale direction are reverse to the case of a horizontal knitted fabric. Accordingly, the horizontal direction in FIG. 9 is the wale direction, and the direction orthogonal to the wale direction is the course direction.

  Here, the fabric with stretchability (stretchable knitted fabric having a stretch direction) refers to other including a direction in which the stretch rate in one direction out of the above-described directions (course direction and wale direction) is orthogonal thereto. It refers to a stretchable knitted fabric having a direction larger than the direction as the stretch direction. In such a stretch knitted fabric, one of the above-mentioned directions (course direction and wale direction) or a direction in the vicinity of the one direction is the direction (maximum) in which the stretch rate is the largest in the knitted fabric. Stretching direction).

  In addition, the body part 11 may join the front body and the back body by the bonding structure using an adhesive agent. Further, the sleeve 12 may be a circular knitted fabric knitted by a circular knitting machine as it is, or a knitted fabric knitted by a flat knitting machine or a circular knitting machine is cut, and then an adhesive is used. It may be joined in a cylindrical shape by a laminating structure using. The sleeve 12 in the undershirt 10 is assumed to be the latter.

In any case, the body part 11 and the left and right sleeve parts 12 knitted separately are bonded together with an adhesive and are not sewn. Furthermore, this undershirt 10 does not have any sewn part, and each part knitted separately is bonded by a bonding structure.
The upper part of the body part 11 and corresponding to the neck of the wearer is formed with a heel that is struck in a shallow U-shape as an opening, and is below the body part 11 and is the waist part of the wearer. The lower end portion of the body is formed as an opening in the portion corresponding to, and the cuff portion for taking out the hand as the opening is formed in the portion corresponding to the wrist portion of the wearer at the end portion of the sleeve portion 12. Has been. The ends of the fabrics in these openings are made of a fabric (stretchable knitted fabric that does not require peripheral processing) whose peripheral edge is cut off.

Furthermore, the characteristic structure of the undershirt 10 is demonstrated with reference to FIG. 10 and FIG. Here, FIG. 10 is a partially enlarged view of the left half of the undershirt 10, and FIG. 11 is a perspective view showing a wearing state of the undershirt 10.
As shown in these drawings, in this undershirt 10, the upper left and right ends of the body part 11 are provided with a bonding structure 112 using an adhesive in order to form a heel part, and the sleeve part 12 is a flat knitting machine. Alternatively, in order to cut a knitted fabric knitted by a circular knitting machine into a cylindrical shape, a bonding structure 120 using an adhesive is provided, and the body 11 and the sleeve 12 are joined at the shoulder. And a bonding structure 110 using an adhesive.

  These bonding structures 110, 112, and 120 basically have the same structure as described later. Among the bonding structures, the bonding structures 112 and 120 are linear, whereas the bonding structure 110 is characterized by being curvilinear and perimeter. Conventionally, an adhesive is used. Joining was impossible. The bonding structures 112 and 120 including the bonding structure 110 are realized by the bonding structure shown below. In the following, since the bonding structures 110, 112, and 120 have the same structure, the bonding structure 120 will be described.

  This bonding structure 120 is a bonding structure for a fabric in which the sleeve 12 (the stretchable fabric 2) is bonded in a cylindrical shape via an adhesive pattern P formed of an adhesive. The bonding structure will be described in detail with reference to FIG. 12 showing the bonding procedure of the cylindrical sleeve portion 12 (FIG. 12C) from the flat fabric (FIG. 12A). 12B is an enlarged view of a portion surrounded by a circle in FIG. 12A, and FIG. 12D is an enlarged view of a portion surrounded by a circle in FIG.

  As shown in FIG. 12, the adhesive pattern P includes an adhesive portion 3 to which the stretchable fabric 2 is continuously bonded by forming an adhesive in a predetermined shape (zigzag shape in FIG. 12), and the adhesive portion 3. And the non-adhesive part 4 to which the stretchable fabric 2 is not adhered by an adhesive, and the adhesive part 3 and the non-adhesive part 4 are in a predetermined direction (in FIG. 12, the arm direction of the sleeve part 12). In the direction along the line).

As described above, the adhesive pattern P is composed of the adhesive part 3 and the non-adhesive part 4, and as shown in FIG. 12, the adhesive is thermally bonded to the adhesive surface of the stretchable fabric 2 and fixed. The shape in plan view.
Further, the bonding portion 3 is a portion formed by continuously repeating a predetermined shape (a zigzag shape in FIG. 12) in a predetermined direction (a direction along the arm direction of the sleeve portion 12 in FIG. 12).

More specifically, in the case where the shape of the bonding pattern P is a zigzag shape, the bonding portion 3 has a minimum repeating unit U constituting the bonding portion 3 of “<” shape or “>” as shown in FIG. "<" Shape or ">" shape, which is the minimum repeating unit U, is a portion that is repeatedly arranged in a plurality of times in the longitudinal direction of the stretchable fabric 2.
The zigzag shape shown in FIG. 12 repeats a predetermined zigzag amplitude (amplitude orthogonal to the stretchable direction of the fabric) and a predetermined zigzag pitch at a fixed period.

On the other hand, the non-bonding part 4 is an opening formed by the bonding part 3 in a plan view, and the stretchable fabric 2 is not bonded by an adhesive.
More specifically, the non-bonding portion 4 is “<” which is the minimum repeating unit U of the bonding portion 3 in the stretchable fabric 2 as shown in FIG. 12 when the shape of the bonding pattern P is a zigzag shape. It is a portion where the stretchable fabric 2 is not bonded because the adhesive is not applied from the opening end of the shape or “>” shape to the inner predetermined region.

Since the non-adhesive portion 4 is a region where the adhesive is not applied, the non-adhesive portion 4 becomes a stretchable portion that is not hindered by the adhesive even if the fabric is stretched in the stretchable direction.
Specifically, when the non-adhesive portion 4 is pulled in the direction in which the fabric is stretched, the non-adhesive portion 4 extends in a stretchable direction as a stretch, so that the stretch is not hindered by the adhesive.
When bonding the stretchable fabrics with the adhesive pattern P in a zigzag shape, the stretch force and stretchability of the stretchable fabrics can be controlled by changing the above-mentioned predetermined zigzag amplitude and the predetermined zigzag pitch. Can do.

In addition, when making the shape of the adhesion pattern P into a zigzag shape, the period is not particularly limited, and does not need to be a constant period as shown in FIG. The period of the zigzag shape may be appropriately determined depending on the fabric characteristics, the bonding position, the manufacturing conditions, and the like.
Further, the shape of the adhesive pattern P is not particularly limited to a zigzag shape, and various adhesive patterns P can be mentioned. Among various shapes of the adhesive pattern P, a zigzag shape or a curve shape is preferable. This is because the shape is easy to apply when applying (applying) the adhesive to the fabric. The adhesive pattern P applicable to the undershirt 10 is characterized in that it is not strip-like or planar but linear.

In addition, the number of repetitions of the bonding portion 3 and the non-bonding portion 4 constituting the bonding pattern P in a predetermined direction may be at least two times, and is not limited to the predetermined number. In addition, when applying to the bonding structure of the undershirt 10, it becomes the predetermined number of times according to the dimension.
Here, when the number of repetitions is 2, the adhesive pattern P is configured to be arranged in the order of the adhesive 3, the non-adhesive part 4, and the adhesive part 3, when the number of repetitions is 3 times or more. The adhesive pattern P has a configuration in which the adhesive part 3, the non-adhesive part 4, the adhesive part 3, the non-adhesive part 4,.

Furthermore, the arrangement pattern of the bonding part 3 and the non-bonding part 4 constituting the bonding pattern P is not particularly limited, and may be irregularly configured.
Although it does not specifically limit as an adhesive agent, For example, as above-mentioned, a thermoplastic resin (synonymous with a thermomeltable resin) is mentioned.
Examples of such thermoplastic resins include polyurethane hot melt resins, polyester hot melt resins, polyamide hot melt resins, EVA hot melt resins, polyolefin hot melt resins, styrene elastomer resins, and moisture curable urethane resins. A hot melt resin, a reactive hot melt resin, or the like is preferably used, and a reactive hot melt resin is particularly preferable. Reactive hot melt resin has high adhesive strength and can be bonded in a short time, so it has a curved line, such as bonding the entire armhole circumference in the body part and the entire arm circumference in the sleeve part, It is also suitably used in places where the bonded shape does not match. The details of the adhesive that does not have thermoplasticity (heat melting property) will be described later.

The undershirt 10 is formed by bonding the sleeve 12 to the armhole to which the adhesive is applied with the bonding pattern P after the buttock of the body 11 is formed by the bonding structure 112. Is done. At this time, the manufacturing apparatus 1000 is used to manufacture the sleeve 12.
As shown in FIG. 12 (B), a bonding structure 120 is formed as shown in FIG. 12 (D) by adhering the flat fabric with the adhesive applied to the sleeve portion 12 by the manufacturing apparatus 1000. The

-Modification of the undershirt of an operation | movement object Below, with reference to FIG. 13, the modification of the undershirt 10 mentioned above is demonstrated. The undershirt which concerns on this modification differs in the point that the adhesion pattern in a bonding structure is not the adhesion pattern P mentioned above but the dotted | punctate adhesion dot pattern D as shown in FIG. Since the other configuration is the same, the description of the undershirt other than the adhesive pattern will not be repeated here. The bonding structure will be described in detail with reference to FIG. 13 showing the bonding procedure of the cylindrical sleeve 12 (FIG. 13C) from the flat fabric (FIG. 13A). 13B is an enlarged view of a portion surrounded by a circle in FIG. 13A, and FIG. 13D is an enlarged view of a portion surrounded by a circle in FIG. 13C.

  As shown in FIG. 13, the adhesive dot pattern D is a stretchable fabric by forming the adhesive in a dot shape (in FIG. 13, a set of points repeated at a pitch L (1) and an interval L (2)). 2 and a non-adhesive portion 104 to which the stretchable fabric 2 is not adhered by the adhesive. The adhesive portion 103 and the non-adhesive portion 104 are repeatedly provided. . In FIG. 13, the three points of the interval L (2) are repeatedly provided at the pitch L (1) in the direction having the stretchability around the arm of the sleeve 12, but this is limited to this. is not.

  The bonding portion 103 and the non-bonding portion 104 exhibit the same effects as the bonding portion 3 and the non-bonding portion 4, respectively. That is, the non-adhesive portion 104 is an area where the adhesive is not applied and becomes a stretchable portion that is not hindered by the adhesive even if the fabric is stretched in the stretchable direction. The non-adhesive portion 104 extends in a stretchable direction as a stretch, and thus exhibits the same effect as the adhesive pattern P that is not hindered by the adhesive.

  As shown in FIG. 13, the pitch L (1) and the interval L (2) may be appropriately determined depending on the fabric characteristics, the bonding position, the manufacturing conditions, and the like. Further, the shape of the point set of the adhesive dot pattern D is not particularly limited to a shape in which a predetermined number of points is repeated, but it is 3 points, 2 points, 1 point, 2 points, 3 points, 2 points, 1 point, 2 points. It may be a point set made up of repeated dot patterns (staggered patterns) such as three points. Furthermore, the size of the bonded portion 103 (the diameter of the dots = the dot diameter) may be any size with the maximum diameter being that the non-bonded portion 104 can be formed between the adjacent bonded portions 103.

  The pitch L (1), the interval L (2), the dot pattern, and the dot diameter are determined by comprehensively considering the fabric elongation strength in the undershirt, the preferred stretch direction in the undershirt, the peel strength, and the like. It should be. The dot diameter is preferably determined in consideration of the adhesive application amount or / and the application area ratio (area ratio of the bonding portion 103 to the bonding portion 103 and the non-bonding portion 104) per unit area of the cloth. Further, the adhesive pattern may be formed by appropriately combining the adhesive pattern P and the adhesive dot pattern D.

-Adhesive in the undershirt to be operated The adhesive constituting the adhesive pattern (adhesive pattern P, adhesive dot pattern D) is not particularly limited, and as described above, it is made of, for example, a thermoplastic resin. A heat-melted adhesive or hot melt is preferably used, but other adhesives will be described below.

It is also possible to use a liquid adhesive (solvent adhesive or water-soluble adhesive) formed by dissolving a resin in a solvent or water as an adhesive constituting the above-described adhesive pattern (particularly, adhesive dot pattern D). .
In the case of using such a liquid adhesive, it is possible to screen-print the above-mentioned adhesive pattern on one of the objects to be bonded and to bond the other object to be bonded in a room temperature environment. It is also possible to form a single adhesive by dissolving a plurality of resins in a solvent. For example, a resin dissolved in a solvent is formed as a base layer on the fabric, and a different resin dissolved in the solvent is formed thereon. It can also be formed as a single adhesive by printing or application. These adhesive forming methods are not particularly limited. In particular, there is an advantage that the solidification rate can be controlled by their reaction by dissolving a plurality of resins in a solvent and using them as one adhesive. It is also possible to control the solidification rate by irradiating the adhesive with UV. Also, by forming different adhesive layers on each fabric to be bonded and bonding the different adhesive layers (the different adhesives formed on each fabric react to adhere to each other) It is also possible to control the solidification rate.

-Operation of the bonding apparatus Before the sleeve part 12 is bonded to the arm hole of the body part 11 in the undershirt 10 described above, the cylindrical long-sleeved sleeve part 12 is manufactured from the flat fabric by the manufacturing apparatus 1000 according to the present embodiment. The operation to be performed will be described. In the following, the operation of manufacturing apparatus 1000 from time T (0) to time T (7) shown in FIG. 7 will be described with reference to FIG. The undershirt to be operated is not the undershirt shown in FIG. 13 (not the undershirt shown in FIG. 13), but the operation of the manufacturing apparatus 1000 can be performed from the coating head 1110 even for the undershirt shown in FIG. The adhesive is the same except that it is applied intermittently to form dots.

  At time T (0), the worker sets a flat fabric as shown in FIG. 6A and presses a start command button (such as a start button). Between time T (0) and time T (1), the coating head 1110 moves from the standby position 1110 (0) to the coating start position 1110 (L1) in the direction indicated by arrow X (2) and in the direction indicated by arrow Y (2). At the same time, the cloth hand 1310 moves from the standby position (the main bonding position of the press unit 1400) to the standby position at the time of application in the direction of arrow X (3) between time T (0) and time T (2). At time T (1), the coating can be started as shown in FIG.

  Between time T (2) and time T (3), the coating head 1110 moves from the coating start position 1110 (L1) to the coating end position 1110 (L2) in the direction indicated by the arrow X (2) and the gear pump motor 1150. Then, the crank motor 1160 is actuated, and the operation of the crank motor 1160 and the coating head driving single-axis robot 1140 applies the adhesive to the fabric with a desired bonding pattern (here, the bonding pattern P shown in FIG. 12B). The

Between time T (3) and time T (4), the coating head 1110 moves from the coating end position 1110 (L2) to the reverse standby position 1110 (L3) in the direction indicated by arrow X (2) and in the direction indicated by arrow Y (1). Move to.
When the coating head 1110 is retracted to the reversal standby position 1110 (L3), the second hollow rectangular column (reversed rectangular column) 1210 is approximately in the direction indicated by the arrow R (2) between time T (4) and time T (5). When the state is reversed by 180 ° to change from the state shown in FIG. 6C to the state shown in FIG. 6D and a desired time (= time T (5) −time T (4)) has elapsed, the second hollow The prism (inverted prism) 1210 is reversely inverted by approximately 180 ° in the direction of the arrow R (1) and returns from the state shown in FIG. 6D to the state shown in FIG.

  At time T (5), the fabric hand 1310 of the transport unit 1300 is advanced in the direction indicated by the arrow Z (2), and the fabric temporarily secured between the first hollow rectangular column (transport square column) 1010 and the fabric hand 1310. Is held (the fabric hand 1310 and the fabric are frictionally engaged), and the temporarily fixed fabric becomes movable in the direction of the arrow X (4) as shown in FIG. 6 (E). The state in which the fabric hand 1310 and the fabric are frictionally engaged continues until the heat press is completed at time T (7), including the time of conveyance between time T (5) and time T (6).

At time T (5), the belt conveyor 1360 of the transport unit 1300 is rotated in the direction of arrow C, the first air cylinder (inside) 1340 of the transport unit 1300 is lowered in the direction of arrow D, and the transport unit 1300 The dough hand 1310 is moved in the direction of arrow X (4). At this time, the cloth temporarily fixed between the first hollow prism (conveyance prism) 1010 and the cloth hand 1310 is sandwiched (the cloth hand 1310 and the cloth are frictionally engaged), and the arrow X ( 4) It is conveyed in the direction as shown in FIG.

  When the fabric hand 1310 arrives at the main bonding position at time T (6), the belt conveyor 1360 of the transport unit 1300 is stopped, and the first air cylinder (inside) 1340 of the transport unit 1300 is raised in the arrow U direction. The Then, the heater unit 1410 of the press unit 1400 is lowered in the direction indicated by the arrow Y (4), and the temporarily fixed dough is managed by the timer by the first hollow rectangular column (conveying rectangular column) 1010 and the heater unit 1410. Only time (= time T (7) −time T (6)) is held. As a result, as shown in FIG. 6F, a desired amount of heat is applied to the fabric from the heater of the heater unit 1410, the adhesive melts, and the cylindrical fabric is permanently bonded.

At time T (7), the press timer expires, the heater unit 1410 of the press unit 1400 is raised in the arrow Y (3) direction, and the dough hand 1310 of the transport unit 1300 is moved in the arrow Z (1) direction. The second air cylinder (outside) 1350 of the transport unit 1300 is lowered in the direction of arrow D.
In this state, the operator pulls out the cylindrical fabric that is permanently bonded by the manufacturing apparatus 1000 from the first hollow rectangular column (conveying rectangular column) 1010 toward the open end, and takes out the cylindrical fabric.

  As described above, according to manufacturing apparatus 1000 according to the present embodiment, for example, the armhole of the sleeve portion is stretched like a knitted fabric constituting an undershirt, and the arm portion of the sleeve portion is formed in a cylindrical shape at the shoulder portion. Prior to bonding to the fabric, the cloth can be bonded to the tube with sufficient adhesive strength when the cylindrical sleeve is manufactured. Furthermore, it is possible to automatically realize continuous bonding of the fabric in a cylindrical shape after applying the adhesive to the planar fabric. Furthermore, a cylindrical fabric can be produced from a planar fabric by adhering the planar fabric without impairing the stretchability of the fabric while ensuring the adhesive strength.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. An example of modification is shown below.
For example, in the above-described embodiment, the member to be bonded is described as a planar member (planar fabric F) having flexibility. However, the present invention is not limited to this and is flexible. The present invention can also be applied to a process of bonding a non-planar member having a property. Specifically, it is a process of bonding the shoulder part of the front body and the back part of the underwear that does not have a sleeve part, more specifically, in a state where the sleeve part 12 is not provided in FIG. 10 and FIG. The present invention can be applied to the process of forming the laminated structure 112. In addition, after forming this bonding structure 112, the sleeve part 12 is joined by forming the bonding structure 110, and the undershirt provided with the sleeve part 12 is manufactured, or after forming this bonding structure 112, a sleeve is formed. It is possible to manufacture an undershirt (described as a tank top) that does not include the sleeve portion 12 without joining the portion 12. When the bonded structure 112 is formed in such a tank top, the adhesive region of the right shoulder part of the front body and the adhesive region of the left shoulder part of the front body are formed into the first hollow rectangular column (conveying prism) 1010. The adherence area of the right shoulder part of the back body and the adherence area of the left shoulder part of the back body are formed into a second hollow prism (inverted prism) 1210 in an S shape in the cross-sectional direction viewed from the armhole side. As such, each will be held. On the contrary, the back body may be held by the first hollow prism (conveying prism) 1010 and the front body may be held by the second hollow prism (inverted prism) 1210. In addition, since such a tank top forms the cylinder part by the right arm hole and the left arm hole by forming the bonding structure 112, at least a part of the cylindrical member is a cylindrical member. It becomes.

In the above-described embodiment, the first and second surfaces of the planar fabric F are described as being held by the fabric holding means so as to face substantially the same upward direction. It is not limited to this. The second surface to which the adhesive is not applied may be in the range of about 150 ° to about 270 ° including the vertical upward direction (180 °) instead of the upward direction. This angle is set in consideration of ease of setting the dough. In such a case, the second hollow prism 1210 is inverted by about 120 ° to about 300 ° (preferably about 170 ° to about 250 °) according to the inclination angle of the second surface. The reversing unit 1200 is not limited to the one that inverts the second hollow prism 1210 by approximately 180 °. As described above, “reversal” in the present invention not only means that the direction of the cloth is exactly reversed (substantially 180 ° rotation), but also means a wider range of direction change. Further, the second hollow rectangular column (reversing rectangular column) 1210 (and the first hollow rectangular column (conveying rectangular column) 1010) is not limited to the hollow rectangular column, and includes a cavity serving as a passage for suction air inside. Alternatively, it may be a prism (processed so as to have a hollow in a solid prism that is not hollow).

  In the above-described embodiment, the application unit 1100 has been described as applying the adhesive to the adhesive region of the first surface, but the present invention is not limited to this. The adhesion region forming means may be realized by a screen printing unit (a configuration including a screen plate, a squeegee and a doctor, a squeegee moving mechanism, etc.) instead of the coating unit 1100.

  In the present invention, when a tubular member is manufactured by applying an adhesive to a flexible member, for example, the adhesive is automatically applied to a flat fabric and then continuously and continuously bonded into a cylindrical shape. And it can utilize suitably for the apparatus which manufactures a cylindrical member (for example, cylindrical cloth).
