Description

  The present invention relates to a cloth bonding apparatus. More particularly, the present invention relates to a mechanism for adjusting a distance between a nozzle that discharges an adhesive and a cloth conveyance device.

  Conventionally, there is a cloth bonding apparatus that bonds a cloth by discharging an adhesive from a nozzle (see, for example, Patent Document 1). The cloth bonding apparatus discharges a heated liquid adhesive from a nozzle between cloths facing each other, and then presses both cloths together. Since the cloth bonding apparatus bonds the cloth and the cloth with an adhesive, it is possible to eliminate the unevenness of the sewing thread that occurs on the cloth surface when sewing with the sewing thread.

  In the cloth bonding apparatus described in Patent Document 1, a belt is hung over a roller provided near the lower side of a nozzle and a roller provided on the downstream side in the cloth transfer direction with respect to the nozzle. The fabric is placed on the belt. The roller rotates by driving a motor. The cloth bonding apparatus transfers the cloth disposed on the belt by the rotation of the roller. The cloth bonding apparatus can adhere the adhesive to the cloth and bond the cloth to the cloth by transferring the cloth. In the cloth bonding apparatus described in Patent Document 1, the distance between the belt and the nozzle can be adjusted according to the type of cloth in order to keep the adhesive application state stable.

FIG. 6 shows the second position. In the first position, the contact portion 162 moves forward by the biasing force of the spring 166. As the contact portion 162 moves forward, the front portion of the lower belt 27 moves upward. In the first position, the lower belt 27 and the nozzle 17 sandwich the cloth. In the present embodiment, the distance between the lower belt 27 and the nozzle 17 in the vicinity of the first position can be adjusted smoothly and finely by a method described later.

  In the second position, the fourth motor 94 rotates counterclockwise (in FIG. 6) from the first position. Due to the rotation of the fourth motor 94, the contact portion 162 moves rearward. The support arm 160 swings counterclockwise (in FIG. 6) about the rotation shaft 141 by the rearward movement of the contact portion 162. As the support arm 160 swings, the front portion of the lower belt 27 moves downward.

  With reference to FIG. 7, the electrical configuration of the cloth bonding apparatus 1 of the present embodiment will be described. The cloth bonding apparatus 1 includes a CPU 200, a ROM 201, a RAM 202, and a storage device 203. The CPU 200 executes reception processing and control processing. The reception process is a process of receiving input information from the key 209, the pedal 208, and the like. The control process is a process for controlling a motor or the like.

  The ROM 201 stores programs executed by the CPU 200, various initial setting parameters, and the like. The RAM 202 temporarily stores timer values, counter values, flags, and the like. The storage device 203 is configured by a nonvolatile memory such as a flash memory or an HDD.

  As shown in FIG. 8, the setting table 70 includes a setting change film thickness setting value storage area 71, a lower belt interval change position storage area 72, and a lower belt adjustment interval storage area 73. The setting change film thickness setting value storage area 71 stores a reference film thickness for changing the adjustment interval of the distance between the nozzle 17 and the lower belt 27 according to the film thickness of the adhesive discharged from the nozzle 17 onto the cloth. The lower belt interval change position storage area 72 stores a position where the adjustment interval of the nozzle 17 and the lower belt 27 is changed according to the interval between the nozzle 17 and the lower belt 27. The lower belt adjustment interval storage area 73 stores a lower belt adjustment interval (second predetermined value interval) to be changed. In this embodiment, the basic adjustment interval (first predetermined value interval) is fixed to 0.1 mm as an example. The operator can set the setting change film thickness, the lower belt interval change position, and the lower belt adjustment interval by operating the key 209.

  The CPU 200 is electrically connected to the ROM 201, the RAM 202, and the storage device 203, respectively. The CPU 200 can access storage areas of the ROM 201, the RAM 202, and the storage device 203.

  The pedal 208 is electrically connected to the CPU 200. The pedal 208 accepts an adhesive supply instruction and supply stop instruction, and a cloth transfer instruction and transfer stop instruction. When the operator depresses the pedal 208, the pedal 208 accepts an adhesive supply instruction and a cloth transfer instruction. When the operator stops the depression of the pedal 208, the pedal 208 accepts an adhesive supply stop instruction and a cloth transfer stop instruction. The CPU 200 recognizes an instruction received by the pedal 208 according to the state of the pedal 208. The operator uses the pedal 208 to adjust the cloth transfer speed. The CPU 200 can recognize the depression amount of the pedal 208. The CPU 200 determines the rotational speeds of the first roller 22 and the first pulley 25 in proportion to the recognized depression amount of the pedal 208.

  The key 209 is electrically connected to the CPU 200. The operator uses the key 209 when performing various operation settings. The CPU 200 recognizes the pressed state of the key 209. The CPU 200 stores various operation setting information in the storage device 203 based on the recognized depression state of the key 209.

  The display drive driver 205 is electrically connected to the CPU 200. The display drive driver 205 is electrically connected to the liquid crystal display unit 207. The CPU 200 displays desired information on the liquid crystal display unit 207 via the display driving driver 205.

The first motor 91, the second motor 92, the third motor 93, and the fourth motor 94 are electrically connected to the motor drive driver 216, respectively. The CPU 200 controls the first motor 91, the second motor 92, the third motor 93, and the fourth motor 94 via the motor drive driver 216. The first motor 91 drives a gear pump (not shown) that supplies the adhesive in the storage chamber 18 (see FIG. 1) to the nozzle 17. The second motor 92 drives the first roller 22 (see FIG. 5) via a rotating shaft and a belt (not shown).

  The 3rd motor 93 is provided in the right side in the base part 11 shown in FIG. The third motor 93 rotates the first pulley 25 by transmitting the rotational driving force to the first pulley 25 via the rotating shaft 141 and the belt (not shown) shown in FIG. The rotating shaft 141 extends rightward within the pedestal 11. The right end of the rotation shaft 141 is connected to the rotation shaft of the third motor 93. The pedestal portion 11 has a support pedestal 4 therein. The support pedestal 4 supports the rotary shaft 141 in a rotatable manner. The first pulley 25 rotates as the third motor 93 rotates. The fourth motor 94 is as described above.

  The air drive driver 214 is electrically connected to the CPU 200. The air drive driver 214 is electrically connected to the air cylinders 21 and 24. The CPU 200 controls the air pressure sent to the air inlets of the air cylinders 21 and 24 via the air driving driver 214. The first roller 22 (see FIG. 5) moves in the vertical direction based on the operation of the air cylinder 21. A support portion (not shown) that supports the nozzle unit 7 (see FIG. 1) moves to a use position for performing the bonding operation and a maintenance position for performing maintenance based on the operation of the air cylinder 24.

  The position detection sensor 43 is electrically connected to the CPU 200. The CPU 200 recognizes whether or not the position detection sensor 43 has detected the detection plate 66 provided on the eccentric cam 65. The CPU 200 controls the movement of the fourth motor 94 to the origin position when the position detection sensor 43 detects the detection plate 66. The CPU 200 inputs a drive amount signal from the origin position of the fourth motor 94 to the first position and the second position of the second pulley 28 to the motor drive driver 216. The CPU 200 controls the drive of the fourth motor 94 based on the signal input to the motor drive driver 216 and controls the movement of the second pulley 28.

  Next, with reference to the flowcharts of FIGS. 9 and 10 and FIGS. 11 and 12, the setting process of each parameter and the adjustment process of the interval between the nozzle 17 and the lower belt 27 will be described.

  The parameter setting process will be described with reference to FIG. The process starts when the user operates the operation panel 210 to select parameter setting. The user presses the UP key 209A or the DOWN key 209C of the operation panel 210 shown in FIG. The CPU 200 recognizes the pressed state of the key 209 and displays the setting change film thickness screen on the liquid crystal display unit 207 (S1). In general, when the film thickness of the adhesive discharged on the cloth is thick, the distance between the nozzle 17 and the lower belt 27 is increased by the film thickness, so that the application state of the adhesive is affected without fine adjustment of the distance. Few. Therefore, when it is thicker than a certain film thickness, it is not necessary to finely adjust the interval between the nozzle 17 and the lower belt 27. Therefore, as shown in FIG. 11, for example, when the film thickness is 200 μm, the adjustment of the interval between the nozzle 17 and the lower belt 27 may be a basic adjustment interval (as an example, an interval of 0.1 mm). In the present embodiment, it is possible to set a reference for the film thickness of the adhesive that requires fine adjustment of the distance between the nozzle 17 and the lower belt 27.

  The CPU 200 displays on the liquid crystal display unit 207 candidates for the setting change film thickness that serves as a reference for the film thickness. The CPU 200 stores the setting change film thickness as a setting change film thickness setting value in the setting table 70 of the storage device 203 when the user presses the-key 209D or the + key 209E and selects the enter key 209B. Store in area 71 (S2).

  As an example, the liquid crystal display unit 207 displays 100 μm as the default value of the setting change film thickness. The liquid crystal display unit 207 displays 50 μm when the user presses the − key 209D, and displays 200 μm when the user presses the + key 209E. When the user presses the ENTER key 209B, the CPU 200 stores the value displayed on the liquid crystal display unit 207 at that time in the setting change film thickness setting value storage area 71 of the setting table 70 (S2). In the present embodiment, as an example, 100 μm is stored as the setting change film thickness (setting 1).

  The user presses the UP key 209A or the DOWN key 209C on the 210 operation panel shown in FIG. The CPU 200 recognizes the pressed state of the key 209 and displays the lower belt interval change position screen on the liquid crystal display unit 207 (S3). In general, when the gap between the nozzle 17 and the lower belt 27 is wide, it takes time to finely adjust the gap between the nozzle 17 and the lower belt 27. Therefore, when the interval between the nozzle 17 and the lower belt 27 is wider than the reference value, it is desirable not to finely adjust the interval between the nozzle 17 and the lower belt 27. In other words, the interval between the nozzle 17 and the lower belt 27 is set to a predetermined reference value, which is an interval change position. If the interval is smaller than the interval change position, the adjustment interval can be reduced. In the present embodiment, by setting the interval change position, it is possible to adjust the range for reducing the adjustment interval and shorten the adjustment time.

  For example, as shown in FIG. 12, when the adjustment range of the interval between the nozzle 17 and the lower belt 27 is 0 mm to 2.3 mm, the interval change position (reference value) is set to “1 mm”. When the distance between the nozzle 17 and the lower belt 27 is in the range of 1 mm to 2.3 mm, the liquid crystal display unit 207 sets the distance between the nozzle 17 and the lower belt 27 to 0.1 mm, which is a basic adjustment interval (first predetermined value interval). Increase or decrease the unit. When the distance between the nozzle 17 and the lower belt 27 is in the range of 0 mm to 1 mm, the liquid crystal display unit 207 displays the image by increasing or decreasing in units of intervals (second predetermined value intervals) set in the setting 3 process (S6) described later. For example, when the interval is set to 0.05 mm in the setting 3 process (S6), which will be described later, the liquid crystal display unit 207 displays the image by increasing or decreasing in units of 0.05 mm.

  For setting the interval change position, for example, “1 mm” is displayed on the liquid crystal display unit 207 as a default value of the interval change position. The liquid crystal display unit 207 displays “0.5 mm” when the user presses the −key 209D, and displays “1.5 mm” when the user presses the + key 209E. When the user presses the ENTER key 209B, the value displayed on the liquid crystal display unit 207 is stored in the lower belt interval change position storage area 72 of the setting table 70 (S4). In the present embodiment, as an example, “1 mm” is stored as the lower belt interval change position (setting 2).

  The user presses the UP key 209A or the DOWN key 209C of the operation panel 210 shown in FIG. The CPU 200 recognizes the pressed state of the key 209 and displays the lower belt adjustment interval screen on the liquid crystal display unit 207 (S5). In the lower belt adjustment interval screen, when the interval between the nozzle 17 and the lower belt 27 is narrower than the interval change position (reference value) set in the process of S3, the interval between the nozzle 17 and the lower belt 27 is increased or decreased. A second predetermined value interval of a certain lower belt adjustment interval is set. In the present embodiment, by setting the second predetermined value interval, the interval between the nozzle 17 and the lower belt 27 can be easily adjusted to a user's desired interval.

  On the lower belt adjustment interval screen, for example, “0.1 mm” is displayed on the liquid crystal display unit 207 as a default value of the lower belt adjustment interval (second predetermined value interval). The liquid crystal display unit 207 displays “0.05 mm” when the user presses the − key 209D. The liquid crystal display unit 207 displays “0.2 mm” when the user presses the + key 209E. When the user presses the ENTER key 209B, the value displayed on the liquid crystal display unit 207 is stored in the lower belt adjustment interval storage area 73 of the setting table 70 (S6). In the present embodiment, as an example, “0.05 mm” is stored as the lower belt adjustment interval (setting 3). When the user performs the setting process of S1 to S6 and operates the operation panel 210 to select the end of parameter setting, the setting process of each parameter is ended.

  Next, with reference to the flowchart shown in FIG. 10, the adjustment process of the gap between the nozzle 17 and the lower belt 27 will be described. The processing starts when the user operates the operation panel 210 to select the lower belt position adjustment. When the process is started, the CPU 200 determines whether or not the user has pressed the + key 209E or the − key 209D (S11). When the user presses the + key 209E or the − key 209D (S11: YES), the CPU 200 determines whether or not the current film thickness is equal to or less than the setting change film thickness setting value (setting 1) in the setting table 70. (S12). The current film thickness is a value that is set in advance by the user as a film thickness discharged from the nozzle 17 onto the cloth and stored in the storage device 203. When the current film thickness is equal to or less than the setting change film thickness setting value (100 μm as an example) in the setting table 70 (S12: YES), the CPU 200 determines that the current gap between the nozzle 17 and the lower belt 27 is below the setting table 70. It is determined whether or not the belt interval change position is less than the set value (setting 2) (S13). The current interval between the nozzle 17 and the lower belt 27 is the value updated in the previous processing of S14.

  For example, when the current interval between the nozzle 17 and the lower belt 27 is equal to or less than the set value (for example, 1 mm) of the lower belt interval change position (S13: YES), the CPU 200 presses the key 209D or the key pressed by the user in S11. Based on the pressed state of the + key 209E, the interval between the nozzle 17 and the lower belt 27 is moved and changed in units of the setting value (setting 3) of the lower belt adjustment interval of the setting table 70 (S14). For example, when the current distance between the nozzle 17 and the lower belt 27 is 0.7 mm and the user presses the −key 209D, the CPU 200 changes the distance between the nozzle 17 and the lower belt 27 to “0.65 mm”. . When the user presses the + key 209E, the CPU 200 changes the interval between the nozzle 17 and the lower belt 27 to “0.75 mm”. When the user presses the ENTER key 209B (S16: YES), the CPU 200 stores the changed distance between the nozzle 17 and the lower belt 27 in the storage device 203 and ends the process.

  If NO in S12 or NO in S13, the distance between the nozzle 17 and the lower belt 27 is changed in units of “0.1 mm” which is a basic value (S15). For example, when the current distance between the nozzle 17 and the lower belt 27 is 1.3 mm and the user presses the −key 209D, the CPU 200 changes the distance between the nozzle 17 and the lower belt 27 to “1.2 mm”. . When the user presses the + key 209E, the CPU 200 changes the interval between the nozzle 17 and the lower belt 27 to “1.4 mm”. When the user presses the ENTER key 209B (S16: YES), the CPU 200 stores the changed distance between the nozzle 17 and the lower belt 27 in the storage device 203 and ends the process. In the case of NO in S16, the CPU 200 returns the process to S11. If NO in S11, the CPU 200 waits until the user presses the − key 209D or the + key 209E. As shown in FIG. 12, the distance between the nozzle 17 and the lower belt 27 is between 2.3 mm and 0 mm, and increases or decreases in units of 0.1 mm from 2.3 mm to 1 mm, and increases or decreases in units of 0.05 mm from 1 mm to 0 mm. To do.

  In the actual adjustment of the distance between the nozzle 17 and the lower belt 27, the CPU 200 controls the motor drive driver 216 in S14 or S15 to rotate the fourth motor 94 by a necessary angle (number of steps). The eccentric cam 65 rotates as the fourth motor 94 rotates. Due to the rotation of the eccentric cam 65, the contact portion 162 moves in the front-rear direction. The support arm 160 swings about the rotation shaft 141 as the contact portion 162 moves. As the support arm 160 swings, the second pulley 28 and the third pulley 29 move in the vertical direction. The lower belt 27 moves together with the second pulley 28 and the third pulley 29, and changes the distance between the lower belt 27 and the nozzle 17.

  As described above, in the cloth bonding apparatus 1, the current adhesive film thickness is smaller than the setting change film thickness (reference film thickness), and the current gap between the nozzle 17 and the lower belt 27 is the lower belt gap change position ( In the following case, the interval between the nozzle 17 and the lower belt 27 can be adjusted with a fine adjustment interval (second predetermined value interval, for example, 0.05 mm interval). Therefore, when the distance between the nozzle 17 and the lower belt 27 is particularly narrow, the cloth bonding apparatus 1 can finely adjust the distance, and the application state of the adhesive is stabilized. When the current adhesive film thickness is thicker than the set change film thickness (reference film thickness), or when the current gap between the nozzle 17 and the lower belt 27 is wider than the lower belt gap change position (reference value), the interval No fine adjustment is required. In this case, the cloth bonding apparatus 1 can shorten the adjustment time by adjusting the distance between the nozzle 17 and the lower belt 27 at a reference distance (as an example, an interval of 0.1 mm). Since the cloth bonding apparatus 1 can arbitrarily change the setting change film thickness (reference film thickness), the lower belt interval change position (reference value), and the adjustment interval (second predetermined value interval), the interval between the nozzle 17 and the lower belt 27 can be changed. Can be easily adjusted to a desired interval.

  The present invention is not limited to the above embodiment, and can be modified as appropriate. For example, the setting change film thickness (reference film thickness), lower belt interval change position (reference value), lower belt adjustment interval (second predetermined value interval), and basic adjustment interval (first predetermined interval) set in the setting table 70 (Value interval) is an example and can be changed as appropriate. A plurality of setting tables 70 may be provided. In this case, the operator sets the setting change film thickness, the lower belt interval change position, and the lower belt adjustment interval in various patterns. The operator can perform a bonding operation by selecting a setting table having a desired pattern.

  In the above embodiment, when the adhesive film thickness is smaller than the set change film thickness and the current distance between the nozzle 17 and the lower belt 27 is equal to or less than the lower belt distance change position, the distance between the nozzle 17 and the lower belt 27 is changed to the first. Adjusted at two predetermined value intervals. A plurality of lower belt interval changing positions may be provided. In this case, for example, the lower belt interval change position has a first change position and a second change position. When the adhesive film thickness is smaller than the set change film thickness, the distance between the nozzle 17 and the lower belt 27 is equal to or smaller than the first change position, the adjustment interval is set to the second predetermined value interval, and the adhesive film thickness is thicker than the reference film thickness. When the interval between the nozzle 17 and the lower belt 27 is equal to or smaller than the second change position, the adjustment interval is set to the second predetermined value interval. The cloth bonding apparatus can finely adjust the distance between the nozzle 17 and the lower belt 27 as required even if the film thickness of the adhesive is larger than the setting change film thickness. A plurality of setting change film thicknesses may be provided. In this case, the cloth bonding apparatus can finely adjust the distance between the nozzle 17 and the lower belt 27 in accordance with the film thickness, and the application state of the adhesive becomes more stable.
