Description

  The present invention relates to a technique for adhering a sheet-like material such as a film or a cloth constituting a garment, and in particular, adhering two or more sheet-like materials with sufficient adhesive strength when adhering such a sheet-like material. The present invention relates to an apparatus for adhering a sheet-like material.

  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.

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

  However, in the bonding method disclosed in Patent Document 1, when pressing, only two cloth pieces are bonded by heating only from one cloth piece side to melt the adhesive. The amount of heat may be insufficient due to heating only from the heat source. In such a case, the adhesive may be bonded without sufficiently melting, and the adhesive strength may not be sufficient. This possibility is particularly high in the case of British sewing shown in FIG. 3 of Patent Document 1 or when the cloth piece is thick. In order to eliminate such a possibility, it is conceivable to increase the amount of heat for heating, but in this way, even if the adhesive can be sufficiently melted by applying a large amount of heat, it is bonded. It may be necessary to cool later.

Furthermore, in the bonding apparatus disclosed in Patent Document 2, since heating is performed before the first fiber and the second fiber are in contact with each other, if the hot melt layer is sufficiently plasticized before the contact, the hot melt layer becomes the first one. There is a possibility that the adhesive strength may not be sufficient due to separation from one fiber, or if a small amount of heat is applied so as to avoid such separation, the hot melt layer is adhered without sufficiently plasticizing and the adhesive strength is It may not be enough.

  In addition, the bonding techniques disclosed in the above-described patent documents all apply an adhesive over the entire width of the bonding region along the conveyance 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.

[Each component configuration]
・ Belt transport unit 1100
The belt conveyance unit 1100 sandwiches the fabric to be bonded with the roller conveyance unit 1200, and conveys the fabric in the arrow T direction while heating the bonding region. The belt conveyance unit 1100 includes an endless conveyance belt 1110 that abuts against the fabric and feeds the fabric in the arrow T direction, a pressure contact roller 1120 that abuts the conveyance belt 1110 on a part of the outer peripheral surface of the conveyance roller 1210, A driving roller 1124 and a plurality of driven rollers 1122 that drive the conveyance belt 1110 in the direction indicated by the arrow R, and a surface opposite to the fabric contact surface of the conveyance belt 1110, are heated through the conveyance belt 1110. The arrow Y (1) between the elevator heater 1130 and the retracted position of the elevator heater 1130 (the prepared position is the same as the retracted position and these may be collectively referred to as the retracted / prepared position) and the operating position. ) Heater lifting / lowering air cylinder 1142 (described only in FIG. 8 to be described later) moved in the -Y (2) direction, and the belt conveying portion 1100 as a retracted position. A retracting air cylinder 1140 that moves in the direction of arrows X (1) -X (2) between the positions (the operation position is the same as the preparation position and may be collectively referred to as the preparation / operation position). (Described only in FIG. 8 described later) and a conveyor belt motor 1150 (described only in FIG. 8 described later) for driving the driving roller 1124 to rotate.

  The belt conveyance unit 1100 is mounted on the belt conveyance unit frame 1410 and is retracted by the retraction air cylinder 1140 for each belt conveyance unit frame 1410 (arrow X (1) side) and preparation / operation position ( Move to arrow X (2) side). If the mechanism can realize the retracted position where the conveyor belt 1110 and the conveyor roller 1210 are separated from each other and the preparation / operation position where the conveyor belt 1110 is wound around the conveyor roller 1210, for example, only the pressure roller 1120 is used as an arrow. A mechanism for moving in the direction indicated by X (1) -X (2) may be used. Furthermore, the moving device is not limited to an air cylinder.

  The conveyance belt 1110 has a belt width corresponding to the width direction length of the adhesion region (length in a direction perpendicular to the conveyance direction of the fabric), and preferably has a belt width longer than the width direction length of the adhesion region. The conveyor belt 1110 is made of a material having excellent heat resistance because the elevating heater 1130 comes into contact therewith, and the fabric contact surface is preferably made of a material that has a high coefficient of friction with the fabric and does not slip during conveyance.

  Two pressure rollers 1120 are provided so as to be symmetric about the conveying roller 1210. The pressure roller 1120 is in contact with the conveyance roller 1210 through the conveyance belt 1110 (and through two sheets of cloth) at the preparation position and the operation position (both indicated by the arrow X (2)). In this case, the position of the pressure roller 1120 is set based on the length of the dough held by the transport roller 1210, the outer diameter of the transport roller, and the like. Since the total length of the conveyor belt 1110 in the preparation / operation position is longer than the total length of the conveyor belt 1110 in the retracted position, the conveyor belt 1110 has elasticity or at least one position of the driven roller 1122 is movable. It is preferable that

The conveyance belt 1110 is driven by a driving roller 1124, and a driving path is defined by a pressure roller 1120 and a driven roller 1122. Note that the position and number of the driven rollers 1122 are not limited to those illustrated.
The elevating heater 1130 is provided between the two pressure rollers 1120, and abuts against the surface of the conveyor belt 1110 opposite to the fabric contact surface at the operation position (arrow Y (2) side) to cause the conveyor belt 1110 to move. Heat the bonding area through. The tip side of the elevating heater 1130 has a shape corresponding to the outer peripheral surface of the transport roller 1210. The length in the width direction of the elevating heater 1130 corresponds to the length in the width direction of the conveyor belt 1110. The elevating heater 1130 is maintained at a desired temperature by a heater temperature controller 1520 (described only in FIG. 8 to be described later), and applies a desired amount of heat to the bonding area of the fabric via the transport belt 1110.

  The heater elevating air cylinder 1142 causes the elevating heater 1130 to approach the conveyor belt 1110 and the elevator heater 1130 abuts the conveyor belt 1110 (moves from the arrow Y (1) side to the arrow Y (2) side. This is limited to the case where the belt conveyance unit 1100 is in the preparation / operation position (arrow X (2) side). The device that moves the elevating heater 1130 in the directions indicated by arrows Y (1) -Y (2) is not limited to the air cylinder.

・ Roller transport unit 1200
The roller transport unit 1200 sandwiches the fabric to be bonded with the belt transport unit 1100, and transports the fabric in the arrow T direction while heating the bonding region. The roller transport unit 1200 has a roller width corresponding to the width of the transport belt 1110 in the width direction, a transport roller 1210 having a built-in heater, and a part of the transport roller 1210 is exposed to contact the transport belt 1110. A cylindrical dough holding portion 1220 provided with a notch (opening) so as to be able to carry out, an illumination lamp 1230 for facilitating the operator to superimpose the dough at the retracted position, and an adhesive region In conjunction with the conveyance of the fabric in the arrow T direction, the cylindrical fabric rotation holding unit 1240 that holds the fabric other than the bonding region and rotates in the arrow R direction, the conveyance roller 1210, and the fabric rotation holding Conveying roller motor 1250 (described only in FIG. 8 to be described later) configured to rotate part 1240.

  The transport roller 1210 has a built-in heater that can heat the outer peripheral surface thereof. Further, since the outer peripheral surface of the transport roller 1210 is a fabric contact surface, it is preferable that the transport roller 1210 is made of a material that has a high coefficient of friction with the fabric and does not slip during transport. The transport roller 1210 is rotated in the direction indicated by the arrow R, and the rotational peripheral speed is synchronized with the speed of the transport belt 1110. In other words, the transport roller 1210 operates in synchronization with the transport belt 1110 when the bonding apparatus 1000 is in the operating position (the arrow X (2) side and the arrow Y (2) side). Transport in the direction.

  The cloth holding portion 1220 has a cylindrical shape that does not rotate, and includes a notch portion having a width corresponding to the width of the transport roller 1210 and a length at which the upper portion of the transport roller 1210 is exposed. The exposed length of the upper part of the conveying roller 1210 corresponds to the installation interval of the pressure roller 1120 so that the conveying belt 1110 contacts the conveying roller 1210 at the preparation / operation position (arrow X (2) side). Is set. Here, the length of contact between the conveying belt 1110 and the conveying roller 1210 is set based on the amount of heat given by the two heaters, the set temperature of the two heaters, the characteristics of the adhesive, and the like. Moreover, since the outer peripheral surface of the cloth holding portion 1220 serves as a cloth sliding surface, it is preferable that the cloth holding section 1220 is made of a material that has a low coefficient of friction with the cloth and that is easily slipped during conveyance.

The dough rotation holding unit 1240 has a cylindrical shape that rotates in the arrow R direction. For example, when the cloth is bonded in the bonding apparatus 1000, there is a roller driving system frame 1400 in which the driving system of the roller conveyance unit 1200 is arranged on the right side while the left side is an open end in the cloth traveling direction. It cannot be an open end and is a non-open end. For this reason, the cloth is caught on the frame 1400 of the roller drive system, and the nipping and conveying are hindered. Moreover, even if it is not caught, if the clamping width of the fabric is small because it corresponds to the width direction length of the adhesion region, the clamping conveyance force does not reach the fabric on the non-open end side. Inhibit. In such a case, the cloth on the non-open end side is pulled so that the bonded area sandwiched and overlapped by the transport belt 1110 and the transport roller 1210 is shifted. In other words, since the fabric on the non-open end side is not conveyed, the adhesion region is conveyed, so that twisting occurs and the adhesion region is pulled out of alignment. In this way, when doughing is not preferable, the bonding area may be shifted, and as a result, the quality of the undershirt may vary. In order to avoid such a problem, the dough rotation holding unit 1240 rotates in the arrow R direction and conveys the dough. Since the cloth rotation holding unit 1240 rotates the cloth that is not the bonding area and is also held at the non-open end side, the cloth can be favorably spread. Specifically, for example, when two sheets of cloth are bonded by the bonding apparatus 1000, the cloth on the open side can be combed by the operator's hand, and the cloth on the non-open side can be combed by the cloth rotation holding unit 1240. The bonding operation can be performed easily and accurately. In addition, since the bonding apparatus 1000 further includes a mechanism for gripping and rotating the open side cloth, the operator can concentrate on the bonding work (work for feeding the cloth while overlapping the bonding areas of the two cloths). It is preferable at the point which can do.

  Moreover, since the outer peripheral surface of the cloth rotation holding unit 1240 is a cloth contact surface, it is preferable that the cloth rotation holding part 1240 is made of a material that has a high coefficient of friction with the cloth and does not slip during conveyance. The cloth rotation holding unit 1240 is rotated in the direction indicated by the arrow R, and the rotation is linked to the nipping and conveyance of the cloth by the conveyance belt 1110 and the conveyance roller 1210. That is, the dough rotation holding unit 1240 operates in conjunction with the transport belt 1110 and the transport roller 1210 when the bonding apparatus 1000 is in the operating position (arrow X (2) side and arrow Y (2) side). And rotating in the direction indicated by the arrow R, the dough is not hindered from being nipped and conveyed in the direction indicated by the arrow T.

The conveyance roller motor 1250 applies a rotational force to the conveyance roller 1210 and the dough rotation holding unit 1240 with a belt (not shown) via the rotation pulley 1242. A cover 1244 is provided to prevent the fabric from being caught.
In the roller conveyance unit 1200 configured as described above, the dough holding unit 1220 may be rotated in the arrow R direction in the same manner as the conveyance roller 1210. If it does in this way, it will be divided into the conveyance roller 1210 provided with the heater, and the cloth holding part 1220 which is not provided with a heater, and will receive cloth. That is, the material to be bonded is conveyed separately into a rotating roller with a heater and a rotating roller without a heater. This point is significantly different from the above-described configuration in which the entire surface of the bonding object is received by a single roller in Patent Document 2. In the bonding apparatus 1000, the fabric receiving portion is divided into a rotating roller that includes a heater and receives the fabric and a rotating roller that does not include the heater and receives the fabric. If comprised in this way, only the contact part with the upper raising / lowering heater 1130 will be exposed, and the conveyance roller 1210 used as high temperature becomes a structure which is not provided with a heater. For this reason, it is difficult for an operator to touch the portion of the conveying roller 1210 that is at a high temperature when performing the work of feeding the dough into the heat press section (the contact portion between the elevating heater 1130 and the conveying roller 1210), and the workability and safety aspects are reduced. Is preferable. In addition, a preferable effect in terms of workability and safety is manifested when the dough holding portion 1220 rotates or does not rotate.

[Control block]
The bonding apparatus 1000 having such a configuration is controlled by the control unit 1300. The control unit 1300 includes, for example, a control panel 1310 provided with various instruments (here, the control panel 1310 is built in some frames 1400) and various operations that are input devices of the operator. Buttons 1320, various display instruments 1330 that are output devices to the operator, two first foot switches 1340 (for approaching) and second foot switch 1350 that are input devices operated by the operator's feet (For separation).

More specifically, the control unit 1300 will be described with reference to the control block diagram shown in FIG.
As shown in FIG. 8, the control unit 1300 receives various input signals according to a program and parameters (such as a conveyance speed) stored in advance, executes arithmetic processing, and outputs output signals (control signals) to various output devices. An arithmetic unit (CPU 1500 in this case) for output, an input interface 1510 for receiving input signals from the operation buttons 1320 and the foot switches 1340 and 1350, and the heaters built in the elevating heater 1130 and the conveying roller 1210 Heater temperature controller 1520 to be controlled, motor drive driver 1530 for controlling the various motors described above, cylinder drive driver 1540 for controlling the various air cylinders described above, and output for turning on / off the illumination lamp Interface 1550 and display instrument 1 A display driver 1560 for displaying various kinds of information 30, and a memory (storing a program and parameters), not shown.

  An input interface 1510, a motor drive driver 1530, a cylinder drive driver 1540, an output interface 1550, and a display driver 1560 are connected to the CPU 1500 via a bus or the like. The heater temperature controller 1520 is connected to the elevating heater 1130 and the heater built in the transport roller 1210, and controls energization of the heater so as to maintain these heaters at a desired temperature. Note that the heater temperature controller 1520 may or may not be connected to the CPU 1500. In the case of connection, for example, when the measured temperature of the heater is within a predetermined range of the set temperature (when it is a desired temperature), the permission signal is output from the heater temperature controller 1520 to the CPU 1500. The received CPU 1500 controls the bonding apparatus 1000 to operate (moving the elevating heater 1130 in the direction indicated by the arrow Y (2) and conveying the fabric in the direction indicated by the arrow T by the conveyance belt 1110 and the conveyance roller 1210). be able to. By controlling in this way, it is possible to prevent the bonding operation from being performed even when the temperature of the heater is low.

In the following description, when the main switch (one of the operation buttons 1320) is turned on, the temperature of the heater (the heater built in the elevating heater 1130 and the conveyance roller 1210) is set to the set temperature by the heater temperature controller 1520. Shall be controlled.
Operation buttons 1320 and foot switches 1340 and 1350 are connected to the input interface 1510, a conveyor belt motor 1150 and a conveyor roller motor 1250 are connected to the motor drive driver 1530, and retracted air is connected to the cylinder drive driver 1540. A cylinder 1140 and a heater elevating air cylinder 1142 are connected, an illumination lamp 1230 is connected to the output interface 1550, and a display instrument 1330 is connected to the display driver 1560. The illumination lamp 1230 is assumed to be lit at any of the retreat position, the preparation position, and the operation position. As described above, the cylinder drive driver 1540 is described as being connected to an air cylinder to control the operation, but may be an electric cylinder instead of an air cylinder. That is, as long as the above-described moving function can be realized, an air driving method, an electric driving method, or another driving method may be used.

The CPU 1500 that has received the input signals from the foot switches 1340 and 1350 controls the bonding apparatus 1000 as follows, for example.
When the CPU 1500 detects that the first foot switch 1340 for approaching is pressed once, the CPU 1500 outputs an approach command signal to the retracting air cylinder 1140, and the belt transport unit 1100 moves to the retracted position (arrow X (1 ) Side) to the preparation / operation position (arrow X (2) side).

  When the CPU 1500 detects that the first foot switch 1340 for approach has been pressed once more, the CPU 1500 outputs an approach command signal to the heater lift air cylinder 1142, and the lift heater 1130 is in the retracted / prepared position (indicated by an arrow). Y (1) side) to the operating position (arrow Y (2) side). At the same time, the CPU 1500 outputs an operation command signal to the conveyance belt motor 1150 and the conveyance roller motor 1250, the conveyance belt 1110 is driven in the direction indicated by the arrow R, and the conveyance roller 1210 and the cloth rotation holding unit 1240 indicate the arrow. Rotated in the R direction. The belt conveyor 1100 moves to the operating position (arrow Y (2) side) of the elevator heater 1130, drives the conveyor belt 1110, and rotates the conveyor roller 1210 and the cloth rotation holding unit 1240. The CPU 1500 executes the interlock control so as to be permitted only when it is on the (arrow X (2) side).

In this state, when the CPU 1500 detects that the second foot switch 1350 for separation is pressed once, the CPU 1500 outputs a separation command signal to the heater lifting / lowering air cylinder 1142, and the lifting / lowering heater 1130 is moved to the operating position. It is moved from the (arrow Y (2) side) to the retreat / preparation position (arrow Y (1) side). At the same time, the CPU 1500 outputs a stop command signal to the conveyor belt motor 1150 and the conveyor roller motor 1250 to stop driving of the conveyor belt 1110 in the direction indicated by the arrow R, and the conveyor roller 1210 and the cloth rotation holding unit 1240. The rotation in the direction of arrow R is stopped.

When the CPU 1500 detects that the second foot switch 1350 for separation has been pressed once more, the CPU 1500 outputs a separation command signal to the retracting air cylinder 1140 so that the belt conveyance unit 1100 can move to the preparation / operation position (arrows). X (2) side) is moved to the retracted position (arrow X (1) side).
When the CPU 1500 detects that both of the foot switches 1340 and 1350 have been pressed for emergency use, a separation command signal is output to the heater ascending / descending air cylinder 1142 and the retracting air cylinder 1140 to convey the conveyor belt motor 1150 and the conveyor roller. The operation of the bonding apparatus 1000 may be urgently stopped by outputting a stop command signal to the motor 1250 for use.

  Control using such a foot switch is an example, and the number of foot switches and the control when the foot switches are pressed are not limited to the above description. In any case, by adopting a foot switch, the operator can use both hands to grip and position the two pieces of fabric to be bonded, and to feed and feed each fabric during nipping and conveying the fabric. The feeding position can be adjusted with both hands.

[Operation]
The operation of the bonding apparatus 1000 having the above structure will be described. In the explanation of the operation, in order to adhere the sleeve part of the undershirt to the body (this body is provided with a cloth double part), the sleeve part (with no adhesive applied) to the armhole of the body (adhesive is pre-applied) As an example, the case of bonding is described. 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 shoulder 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.

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 110 will be described.

  The bonding structure 110 is a method of attaching a fabric by bonding a body part 11 (elastic fabric 1) and a sleeve 12 (elastic fabric 2), which are elastic fabrics, through an adhesive pattern P formed by an adhesive. It is a mating structure. With reference to FIG. 12 which shows the adhesion procedure of the body part 11 and the sleeve part 12, this bonding structure is demonstrated in detail. In FIG. 12, the body joint part of the sleeve part 12 is superimposed on the front side of the sleeve joint part of the body part 11 (the sleeve part 12 is on the upper side). It does not matter even if the garment joint part of the sleeve part 12 is overlapped on the back side (the garment part 11 is up).

  As shown in FIG. 12, the adhesive pattern P includes an adhesive portion 3 to which the stretchable fabric 1 and the stretchable fabric 2 are continuously bonded by forming an adhesive in a predetermined shape (zigzag shape in FIG. 12). The adhesive portion 3 is formed with an opening in a plan view, and the stretchable fabric 1 and the stretchable fabric 2 are not bonded by an adhesive, and the adhesive portion 3 and the nonbonded portion 4 are in a predetermined direction ( In FIG. 12, it is repeatedly provided in a direction having stretchability around the arm of the sleeve 12.

As described above, the adhesive pattern P is composed of the adhesive portion 3 and the non-adhesive portion 4, and the adhesive is bonded to the adhesive surfaces 1a of the stretchable fabric 1 and the stretchable fabric 2, as shown in FIG. It means the shape in plan view of the bonded portion that is thermally bonded to the surface 2a.
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 having elasticity along the arm of the sleeve 12 in FIG. 12). is there.

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 in which the stretchable fabric 1 and the stretchable fabric 2 are repeatedly and repeatedly arranged in a direction having stretchability. That's it.

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-adhesive part 4 is an opening formed by the adhesive part 3 in a plan view, and the stretchable fabric 1 and the stretchable fabric 2 are not bonded by an adhesive.
More specifically, the non-bonding portion 4 is the minimum repetition of the bonding portion 3 in each of the stretchable fabric 1 and the stretchable fabric 2 as shown in FIG. 12 when the shape of the adhesive pattern P is a zigzag shape. This is a portion where the adhesive fabric is not applied from the opening end of the “<” shape or “>” shape, which is the unit U, to the inner predetermined region, and the stretchable fabric 1 and the stretchable fabric 2 are not bonded.

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 undershirt 10 is formed by bonding the sleeve portion 12 to the armhole to which the adhesive is applied with the bonding pattern P after the buttock of the body portion 11 is formed by the bonding structure 112. Is done. At this time, the bonding apparatus 1000 is used. In addition, it is also preferable that the bonding structures 112 and 120 are bonded using the bonding apparatus 1000. In addition, when the periphery is folded and bonded as a peripheral processing instead of bonding the fabrics of different parts, the peripheral edge of one fabric having an adhesive applied to the peripheral portion is bonded using the bonding apparatus 1000. It is also preferable to do.

As shown in FIG. 12A, the bonding structure 110 is bonded as shown in FIG. 12B by bonding the sleeve portion 12 and the arm hole of the body portion 11 to which the adhesive is applied by the bonding apparatus 1000. Is formed. In the following description, it is the same direction as the direction shown in FIG. 12A, and the body part 11 is on the right side (the cloth rotation holding part 1240 side) in the cloth conveying direction in the bonding apparatus 1000.
The sleeve part 12 is set on the left side (conveying roller 1210 side) in the cloth conveying direction.

-Operation | movement of an adhesion | attachment apparatus Adhesive agent is previously apply | coated to the armhole of the body part 11 in the undershirt 10 mentioned above, and the operation | movement which adhere | attaches the sleeve part 12 on the armhole of the body part 11 by the adhesive device 1000 which concerns on this Embodiment is demonstrated. . In the following, the operation from the state in which the bonding apparatus 1000 is in the retracted position (FIGS. 2A, 6A, and 7A) and the illumination lamp 1230 is lit is performed. explain.

  First, as shown in FIG. 6A, an operator prepares a body part 11 and a sleeve part 12 and sets the body part 11 and the sleeve part 12 in the vicinity of the conveying roller 1210 of the bonding apparatus 1000. An operator puts the adhesive region of the sleeve 12 on the adhesive region where the adhesive is applied in the body part 11, and positions and sets the adhesive region on the transport roller 1210. At this time, the illumination lamp 1230 is lit and can be easily positioned.

  When the operator depresses the first foot switch 1340 in this state, the belt conveyance unit 1100 is moved from the retracted position (arrow X (1) side) to the preparation / operation position (arrow X (2) side). As shown in FIG. 6B, at the position of the transport roller 1210, from the transport roller 1210 side to the body part 11, the adhesive part 3, and the sleeve part 12, the transport roller 1210 and the transport belt 1110 The sleeve part 12 is clamped. At this time, the conveyor belt 1110 and the elevating heater 1130 are at the positions shown in FIGS. 2 (B) and 7 (B).

  When the operator depresses the first foot switch 1340 in this state, the elevating heater 1130 is moved from the retracted / prepared position (arrow Y (1) side) to the operating position (arrow Y (2) side) Further, the conveyance belt 1110 is driven in the direction indicated by the arrow R, and the conveyance roller 1210 and the fabric rotation holding unit 1240 are rotated in the direction indicated by the arrow R, so that the two fabrics are nipped and conveyed in the direction indicated by the arrow T. At this time, the conveyor belt 1110 and the elevating heater 1130 are at the positions shown in FIGS. 2 (C) and 7 (C).

  In this way, when two fabrics are being held and conveyed, the thermoplastic resin (adhesive) interposed between the stretchable fabrics is heated and pressurized from both sides of the two fabrics to melt. As a result, the adhesive is liquefied, and then the stretchable fabrics are joined by cooling and solidification. More specifically, in the bonding apparatus 1000, the bonding surfaces 1a and 2a of the stretchable fabric 1 and the stretchable fabric 2 are combined to form a predetermined adhesive pattern P between the stretchable fabric 1 and the stretchable fabric 2. A thermoplastic resin is interposed and placed on the bonding device 1000, and the thermoplastic resin interposed between the stretchable fabric 1 and the stretchable fabric 2 is heated and pressed from both sides of the two fabrics to melt. By doing so, the thermoplastic resin is melted by heat, and then the elastic fabric 1 and the elastic fabric 2 are fixed by being removed from the heater, cooled and solidified.

In this bonding apparatus 1000, in order to heat the fabric from both the upper and lower directions of the fabric (both directions in which the fabric is sandwiched), a large amount of heat is applied to the fabric from the heater in which the elevating heater 1130 and the conveyance roller 1210 are built. Even if not, the thermoplastic resin (adhesive) can be sufficiently melted by heat. When this is heated from a heater disposed only on one side, it is necessary to apply a large amount of heat from this one heater so that the thermoplastic resin can be sufficiently melted by one heater. Therefore, it is necessary to increase the set temperature of the heater. If it does in this way, the temperature of cloth | dough will become high temperature too much, and the cooling and solidification of the thermoplastic resin after passing a heater will become inadequate, and if it removes | pinches, an adhesion part may be taken off. In order to avoid this, a cooling mechanism is required. However, since this bonding apparatus 1000 is heated by a relatively low temperature heater from both sides, such a cooling mechanism is not required, and the thermoplastic resin is sufficiently cooled and solidified by natural cooling after passing through the heater. . The bonding apparatus 1000 can simplify the apparatus configuration in that it does not require a cooling mechanism.

  When the operator recognizes the end of the bonding area to be bonded in this operation (recognizes that the sleeve portion 12 is bonded to the entire circumference of the armhole of the body portion 11), the operator presses the second foot switch 1350. To do. The elevating heater 1130 is moved from the operation position (arrow Y (2) side) to the retreat / preparation position (arrow Y (1) side), and further, the driving of the conveyor belt 1110 in the arrow R direction is stopped. At the same time, the rotation of the transport roller 1210 and the dough rotation holding unit 1240 in the arrow R direction is stopped.

When the operator further depresses second foot switch 1350, belt conveyance unit 1100 is moved from the preparation / operation position (arrow X (2) side) to the retracted position (arrow X (1) side). Thereafter, the operator removes the body part 11 to which the sleeve part 12 is bonded from the bonding apparatus 1000, whereby the work of bonding the sleeve part 12 to the arm hole of the body part 11 is completed.
In addition, when the operator recognizes that the bonding area has shifted in the middle of the bonding work by sandwiching and transporting the two pieces of fabric in this way and wants to temporarily stop the bonding work, the worker can move the second foot. A switch 1350 is pressed. The elevating heater 1130 is moved from the operation position (arrow Y (2) side) to the retreat / preparation position (arrow Y (1) side), and further, the driving of the conveyor belt 1110 in the arrow R direction is stopped. At the same time, the rotation of the transport roller 1210 and the dough rotation holding unit 1240 in the arrow R direction is stopped. For this reason, the bonding operation is temporarily stopped.

  Further, when releasing and setting the sandwich of the two pieces of fabric, the operator further depresses the second foot switch 1350 to set the belt conveying unit 1100 to the preparation / operation position (arrow X (2) side). ) To the retracted position (arrow X (1) side), the two fabrics are reset, and when the operator presses the first foot switch 1340, the two fabrics are clamped. When the operator further presses down the first foot switch 1340, the nipping and conveying of the two pieces of fabric is restarted, and the bonding operation is resumed.

  In this way, the bonding pattern P intervening between the stretchable materials can be formed in a zigzag shape, and a fabric bonding structure capable of controlling the stretch force and stretchability of the stretchable materials can be realized. By finishing the bonded portion very thinly compared to stitching, it is possible to realize an undershirt 10 that is comfortable to touch and does not resonate with the outer.

  In addition, when the body part 11 and the sleeve part 12 to which the adhesive is applied are bonded by the bonding apparatus 1000, as shown in FIG. 12, it is bonded to the peripheral edge on the front side of the armhole without turning the undershirt 10 upside down. The agent is applied, and the sleeve portion 12 is bonded to the upper side. By doing in this way, even if the adhesion pattern protrudes to the end side with the coating device, even if the adhesion portion shifts with the adhesion device 1000, it can be hidden by the sleeve portion 12 so that it cannot be seen from the table. Even if it protrudes to the opposite side of the end portion, it is preferable that the sleeve portion 12 is slightly overlapped and adhered so that it cannot be seen from the front.

  Further, in the bonding of the arm holes and the like as described above, when the fabrics are overlapped and heated and bonded together, the appearance of the overlapped portion may be deteriorated depending on the shape of the fabric or / and the overlapping portion. In such a case, in the step before the bonding by the bonding apparatus 1000, the material is preliminarily bonded and superposed without giving a sufficient amount of heat for bonding to the fabric (the thermoplastic resin adhesive is not completely melted). In this state, the cloth temporarily bonded to the bonding apparatus 1000 may be supplied, and in the bonding apparatus 1000, the operator may perform the main bonding while finely adjusting the overlapping position as necessary. For temporary bonding, the dough may be set in a frame similar to the dough shape, overlapped automatically or manually in a state where the dough is not generated so much, and pressed without applying (so much) heat.

As described above, according to the bonding apparatus 1000 according to the present embodiment, when bonding doughs having stretchability through an adhesive, heat and pressure are applied from both sides of the two doughs, so that sufficient bonding is achieved. Can be bonded with strength. Furthermore, since the cloth rotation holding unit also rolls and conveys the cloth other than the bonding area, the two cloths can be bonded without shifting the predetermined bonding position. Furthermore, since the adhesive is applied in a desired adhesive pattern, it is possible to adhere 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.

  In the present invention, when sheet-like materials having elasticity such as films, webs, and fabrics are bonded to each other via an adhesive, adhesion without interfering with the elasticity of the fabrics is ensured while ensuring the adhesive strength. It can utilize for the adhesion | attachment apparatus of the sheet-like material which can do.
