本发明提供一种布粘接装置。布粘接装置(1)包括将粘接剂朝布排出的喷嘴(45)。板状的盖部件(51)固定于支撑喷嘴(45)的支撑部(40)。布的粘接作业时，盖部件(51)位于喷嘴(45)与操作者之间，从而防止气体从喷嘴(45)朝操作者侧直接流动。盖部件(51)包括第一气体传感器(53)和第二气体传感器。基座部(11)在喷嘴(45)的正面侧下方包括送出风扇(56)。送出风扇(56)通过孔部(55)从操作者侧吸入空气，并从孔部(57)朝喷嘴(45)侧送出空气。在由第一气体传感器(53)和第二气体传感器检测出的气体浓度中的至少一方为规定值以上时，布粘接装置的CPU增大送出风扇(56)的输出。因此，布粘接装置(1)能高效地除去喷嘴(45)排出的粘接剂产生的气体。

Description

布粘接装置
技术领域
本发明涉及一种布粘接装置。更具体而言，本发明涉及在布上附着粘接剂并压接、从而将布与布粘接的布粘接装置。
背景技术
布粘接装置不是用针和缝线来缝制布，而是用粘接剂将布与布粘接。布粘接装置将常温下固化的粘接剂加热、熔融，并将熔融后的液态粘接剂从喷嘴排出、使其附着在布上。布粘接装置利用滚筒来加压并移送附着有粘接剂的布，从而将布与布粘接。由于粘接的布不使用缝线，因此布上不产生凹凸。这种布粘接装置中，从喷嘴排出的熔融状态的粘接剂有时会产生气体。因此，这种布粘接装置中，为了防止操作者长时间吸入气体，较为理想的是除去气体。
日本特许公开1993年第269336号公报披露了一种收集从粘接剂的容器释放出的气体状释放物的收集装置。日本特许公开1996年第252405号公报披露了一种除去熔融材料产生的蒸汽的蒸汽除去装置。
上述公报记载的装置构造复杂，且无法根据气体的产生状况而将该气体除去。因此，上述公报记载的装置无法高效地除去熔融粘接剂产生的气体。
发明内容
本发明的目的在于提供一种能高效地除去从喷嘴排出的粘接剂产生的气体的布粘接装置。
技术方案1记载的布粘接装置包括：将粘接剂朝布排出的喷嘴、以及根据操作者的操作朝上述喷嘴供给上述粘接剂的供给部，包括：切断气体从上述喷嘴朝上述操作者流动的盖部件、从上述操作者侧朝上述喷嘴侧送出空气的送出机构、检测上述喷嘴排出的上述粘接剂产生的气体的浓度的浓度检测部、以及根据上述浓度检测部的检测结果来控制上述送出机构的动作的送出控制部。
技术方案1记载的布粘接装置中，即使在喷嘴排出的粘接剂产生气体时，也能以盖部件这样的简易结构容易地降低朝操作者侧流动的气体的量。此外，布粘接装置能根据粘接剂产生的气体的浓度来控制送出机构的动作，因此，能根据气体浓度高效地除去气体。
技术方案2记载的布粘接装置还包括：吸引并排出上述气体的吸引机构、以及根据上述浓度检测部的检测结果来控制上述吸引机构的动作的吸引控制部。
技术方案2记载的布粘接装置中，通过送出机构和吸引机构动作，能更可靠地除去气体。此外，布粘接装置能根据气体浓度来控制吸引机构的动作，因此，能根据气体浓度高效地除去气体。
技术方案3和4记载的布粘接装置中，在由上述浓度检测部检测出的上述气体的浓度为规定值以上时，上述供给部停止朝上述喷嘴供给上述粘接剂。因此，布粘接装置能将气体浓度抑制成较低。
技术方案5记载的布粘接装置还包括检测上述送出机构是否正在动作的动作检测部，在上述动作检测部检测出上述送出机构未在动作时，上述供给部停止朝上述喷嘴供给上述粘接剂。送出机构未在动作时，不产生气体。因此，布粘接装置能更可靠地将气体浓度抑制成较低。
技术方案6记载的布粘接装置中，上述送出控制部和上述吸引控制部能分别按至少大输出和小输出这两个等级来控制上述送出机构和上述吸引机构的输出，在由上述浓度检测部检测出的上述浓度为第一规定值以上时，上述送出控制部和上述吸引控制部分别将上述送出机构和上述吸引机构的输出控制成大输出，在由上述浓度检测部检测出的上述浓度不到上述第一规定值时，上述送出控制部和上述吸引控制部分别将上述送出机构和上述吸引机构的输出控制成小输出。布粘接装置以第一规定值为基准，按两个等级来切换送出机构和吸引机构的输出。因此，布粘接装置能以简便的处理高效地除去气体。
技术方案7记载的布粘接装置中，在由上述浓度检测部检测出的上述气体的浓度为比上述第一规定值大的规定值、即第二规定值以上时，上述供给部停止朝上述喷嘴供给上述粘接剂。也就是说，即使将送出机构和吸引机构的输出设为大输出时气体浓度也较高时，布粘接装置停止粘接剂的供给。因此，布粘接装置能更可靠地将气体浓度抑制成较低。

具体实施方式
下面，参照附图来说明本发明的布粘接装置1。
参照图1～3，对布粘接装置1的结构进行说明。将图1的右斜下方、左斜上方、右斜上方、左斜下方分别作为布粘接装置1的前方、后方、右方、左方。
如图1和图2所示，布粘接装置1包括：基座部11、立柱部12、臂部13。基座部11呈将左右方向作为长边方向的大致长方体形状。基座部11固定于工作台(未图示)。立柱部12从基座部11的右端朝铅垂上方延伸。臂部13与立柱部12的上端连接，并朝立柱部12的左侧面的左方突出。
基座部11在其内部包括按压并移送布的下移送滚筒25、第三马达93(参照图4)等。下移送滚筒25与后述的上移送滚筒24一起按压并移送布。第三马达93驱动下移送滚筒25。基座部11作为支撑立柱部12的基座起作用，立柱部12支撑臂部13。如图1所示，臂部13的左端部从后方起依次对梁部14、贮存室26、泵壳体31予以支撑。臂部13在其内部包括第一马达91(参照图4)、第二马达92(参照图4)等。第一马达91驱动齿轮泵35(参照图4)。第二马达92驱动上移送滚筒24。
下面，对梁部14、贮存室26、泵壳体31依次进行说明。对梁部14和与梁部14连接的滚筒保持部20进行说明。如图1所示，梁部14包括：主体部15、弹簧支撑部16、柱部17。主体部15是从臂部13的左侧后端部朝左方水平延伸的部件。主体部15的左右方向的长度是基座部11的左右方向的长度的大致三分之一。弹簧支撑部16呈板状，从主体部15的左端部朝前方水平延伸。弹簧支撑部16的前后方向的长度是基座部11的前后方向的长度的大致二分之一。如图1和图3所示，柱部17以与水平面成大致45度的角度从主体部15朝前下方延伸。如图3所示，柱部17的下端部从基座部11离开。
如图1所示，弹簧支撑部16在其前方侧的前端部上具有孔(未图示)。弹簧支撑部16将轴部19支撑成能上下移动。轴部19插通弹簧18。轴部19的上端部分插入弹簧支撑部16的孔内。柱部17在其下端部分的左侧具有沿左右方向延伸的轴部。轴部对滚筒保持部20的后端部21予以支撑。滚筒保持部20以上述轴部为摆动中心使前端部22在上下方向上摆动。主体部15在弹簧支撑部16的右侧包括气缸41。气缸41移动后述支撑部40的位置。
如图3所示，滚筒保持部20的前端部22将上移送滚筒24支撑成能旋转。上移送滚筒24呈圆柱状。上移送滚筒24位于喷嘴45的后方附近。喷嘴45从支撑部40朝左方突出。滚筒保持部20在比中央稍靠前方侧的上表面具有支撑部23。支撑部23对插通于弹簧18的轴部19的下端予以支撑。弹簧18介于弹簧支撑部16与轴部19的下部之间。弹簧18通过将轴部19朝下方施力，将与轴部19连接的滚筒保持部20朝下方施力。
下面对贮存室26进行说明。如图1和图2所示，贮存室26呈将上下方向作为长边方向的大致长方体形状。贮存室26从臂部13左侧的泵壳体31的后方部分朝上方延伸。贮存室26包括：主体部27、盖部28、盖轴部29。主体部27的形状呈上部开口的有底筒状。盖部28覆盖主体部27的上部开口。盖轴部29将盖部28支撑成能开闭。贮存室26将粘接剂贮存于主体部27的内部。贮存室26根据需要将所贮存的粘接剂朝齿轮泵35(参照图4)和喷嘴45供给。
下面对泵壳体31和与泵壳体31连接的支撑部40进行说明。如图1和图2所示，泵壳体31包括第一泵壳体32和第二泵壳体33。第一泵壳体32是大致立方体形状的部件。第一泵壳体32利用四个螺钉固定于臂部13的左侧面。第一泵壳体32在其左侧具有凹部(未图示)。第一泵壳体32在其凹部内包括齿轮泵35(参照图4)。齿轮泵35将适量的粘接剂高精度地朝喷嘴45供给。第二泵壳体33利用四个螺钉固定于第一泵壳体32的左侧，从而覆盖齿轮泵35。第一泵壳体32和第二泵壳体33形成泵室。齿轮泵35将粘接剂朝喷嘴45加压供给。
如图2所示，第二泵壳体33在其下部的左侧包括轴部39。轴部39将支撑部40支撑成能摆动。第一泵壳体32的上下方向的长度与臂部13的上下方向的长度大致相同。第二泵壳体33的左右方向的位置与基座部11的左右方向中央的位置大致相同。虽未图示，但泵壳体31在其内部包括两个路径。第一路径将粘接剂从贮存室26朝齿轮泵35引导。第二路径将粘接剂从齿轮泵35朝支撑部40引导。
支撑部40的形状呈将上下方向作为长边方向的大致长方体状。支撑部40的下端部与基座部11之间存在极小的间隙。支撑部40在其上端部包括驱动传递部43。驱动传递部43对气缸41的可动部42的前端部予以支撑。气缸41的可动部42前后移动时，支撑部40以轴部39为摆动中心在前后方向(图3的箭头A方向)上摆动。
如图1和图3所示，喷嘴45从支撑部40的下端部朝左侧突出。喷嘴45呈圆筒形。通过气缸41的可动部42前后移动，喷嘴45在操作者进行布的粘接作业时的位置(使用位置)与操作者进行维护时的位置(维护位置)之间移动。喷嘴45包括排出粘接剂的排出口(未图示)。喷嘴45位于使用位置时，排出口与基座部11相对。操作者进行粘接作业时，在相对配置的两层布之间插入喷嘴45。齿轮泵35通过支撑部40内部的路径(未图示)将粘接剂朝喷嘴45供给。喷嘴45从排出口朝布排出粘接剂。其结果是，粘接剂附着在位于喷嘴45下方的布的表面上。
如图1～图3所示，布粘接装置1包括盖部件51。板状的盖部件51的右端部利用三个螺钉52固定于支撑部40的正面。盖部件51从支撑部40朝左方延伸。盖部件51与喷嘴45相对。因此，盖部件51防止气体从喷嘴45朝操作者侧直接流动。盖部件51的材质是透明的合成树脂。因此，操作者能容易地从盖部件51的正面侧观察确认在盖部件51的背面侧进行的布的粘接工序。操作者通过拆下螺钉52，能将盖部件51拆下。因此，操作者能容易地进行布粘接装置1的清扫和零件更换等。
如图1和图2所示，盖部件51在其正面侧的中心包括第一气体传感器(gas sensor)53。第一气体传感器53对熔融的粘接剂产生的气体的浓度进行检测。第一气体传感器53是周知的气体传感器。如图3所示，盖部件51在第一气体传感器53的配设位置的背面侧、也就是在盖部件51的背面包括第二气体传感器54。第二气体传感器54是与第一气体传感器53相同的气体传感器。一般而言，将常温下固化的粘接剂加热、熔融时，有时粘接剂会产生气体。布粘接装置1利用第一气体传感器53来检测操作者侧的气体浓度，并利用第二气体传感器54来检测喷嘴45侧的气体浓度。布粘接装置1通过准确地检测出盖部件51的正面侧和背面侧的气体浓度，能进行更合适的动作。第一气体传感器53和第二气体传感器54与CPU101(参照图5)电连接。
布粘接装置1在其基座部11内包括送出风扇56。如图1所示，基座部11在其上表面上具有孔部57，且在其正面具有孔部55。孔部57位于上移送滚筒24的下方，且位于处在使用位置的喷嘴45的后方。下移送滚筒25(参照图4)的一部分从孔部57朝上方稍微突出。孔部55位于基座部11的正面上部。孔部55的左右方向位置与孔部57的左右方向位置相同。如图3所示，送出风扇56通过孔部57以从前下方面对喷嘴45的角度配置于孔部55。送出风扇56从基座部11的正面侧(操作者侧)吸入空气。送出风扇56从孔部57朝喷嘴45侧送出空气。因此，即使在熔融的粘接剂产生气体时，布粘接装置1也能以简易的结构来降低朝操作者侧流动的气体的量。
布粘接装置1包括吸引机构60。吸引机构60包括管61和吸引风扇62。如图1所示，管61位于梁部14的左后方，沿上下方向延伸。管61的下部朝斜前方弯曲。管61的下端部的开口朝向喷嘴45侧。吸引风扇62安装于管61的下端部的开口。吸引风扇62吸入空气，将该空气送入管61内。因此，即使在熔融的粘接剂产生气体时，布粘接装置1也能快速除去气体。如图3所示，吸引风扇62配置在送出风扇56的空气送出方向上。因此，布粘接装置1能高效地除去气体。
参照图4，对布粘接装置1的内部构造进行说明。如图4所示，布粘接装置1在其内部包括第一马达91、第二马达92、第三马达93等。第一马达91驱动齿轮泵35。第二马达92驱动上移送滚筒24。第三马达93驱动下移送滚筒25。
第一马达91通过转轴121将旋转驱动力传递给齿轮泵35，从而驱动齿轮泵35。第一马达91位于臂部13的内部，且位于泵壳体31与臂部13连接的部分的右方。转轴121在泵壳体31内从第一马达91的转轴朝左方延伸。齿轮泵35将适量的粘接剂朝喷嘴45(参照图1～图3)供给。
第二马达92通过转轴126、127、128和皮带129、130将旋转驱动力传递给上移送滚筒24，从而驱动上移送滚筒24旋转。第二马达92位于臂部13的内部，且位于梁部14与臂部13连接的部分的右方。转轴126从第二马达92的转轴朝左方延伸，在主体部15内贯穿。转轴126的左侧前端部位于柱部17内。转轴126的左侧前端部对带轮予以支撑。转轴127的右侧前端部延伸到柱部17的下侧端部内，转轴127的左侧前端部延伸到滚筒保持部20的后端部21内。转轴127的右侧前端部和左侧前端部分别对带轮予以支撑。

第三马达93通过转轴96和皮带95将旋转驱动力传递给下移送滚筒25，从而驱动下移送滚筒25。第三马达93位于基座部11的右端部内。下移送滚筒25呈圆柱形状，固定于转轴96。下移送滚筒25位于上移送滚筒24的下方，且位于基座部11内。基座部11在其内部具有支撑基座4。支撑基座4将转轴96支撑成能旋转。皮带95在基座部11内张设于第三马达93的转轴的带轮与转轴96右端的带轮之间。下移送滚筒25通过第三马达93的旋转而旋转。上移送滚筒24和下移送滚筒25通过旋转来按压位于上移送滚筒24与下移送滚筒25之间的布并沿着从前方朝向后方的进给方向移送布。
参照图5，对布粘接装置1的电气结构进行说明。如图5所示，布粘接装置1包括CPU101、ROM102、RAM103和存储装置155。CPU101接收输入信息和检测信息，并执行控制处理等。输入信息是输入后述的键112等输入装置的信息。检测信息是由各种传感器、编码器等检测出的信息。控制处理是控制各种马达、送出风扇56和吸引风扇62等的处理。ROM102存储由CPU101执行的程序和各种初始设定参数等。RAM103临时存储计时器、计数器、标志等。存储装置155存储操作者输入的各种设定信息。CPU101与ROM102、RAM103、存储装置155分别电连接。CPU101能访问ROM102、RAM103、存储装置155的存储区域。
踏板111、键112和温度传感器113分别与CPU101连接。踏板111配置于设置布粘接装置1的工作台(未图示)的下方。操作者能用脚来操作踏板111。CPU101识别踏板111的踩下量。CPU101根据识别出的踏板111的踩下量来确定上移送滚筒24和下移送滚筒25的旋转速度。键112配置于工作台上。CPU101识别操作者对键112的按下状态。CPU101根据识别出的键112的按下状态来进行各种处理。温度传感器113配置于贮存室26、泵壳体31和支撑部40。CPU101通过识别由温度传感器113检测出的温度来识别贮存室26、泵壳体31和支撑部40内部的粘接剂的温度。
第一编码器121、第二编码器122和第三编码器123分别与CPU101连接。第一编码器121检测第一马达91的旋转量。第二编码器122检测第二马达92的旋转量。第三编码器123检测第三马达93的旋转量。CPU101通过识别由编码器121～123检测出的旋转量的信息来识别马达91～93的实际旋转速度。
第一气体传感器53和第二气体传感器54分别与CPU101连接。如上所述，第一气体传感器53检测盖部件51正面侧的气体浓度。第二气体传感器54检测盖部件51背面侧的气体浓度。CPU101识别由第一气体传感器53和第二气体传感器54检测出的气体浓度。CPU101根据识别出的气体浓度来控制送出风扇56和吸引风扇62的动作。CPU101还能在气体浓度达到规定值以上时停止粘接剂从喷嘴45的排出。处理的细节将在后面说明。
显示驱动用驱动器131与CPU101连接。液晶显示部141与显示驱动用驱动器131连接。CPU101通过显示驱动用驱动器131使期望的像显示于液晶显示部141。液晶显示部141配置于工作台上，显示操作者进行的设定的信息等。空气驱动用驱动器132与CPU101连接。气缸41与空气驱动用驱动器132连接。CPU101通过空气驱动用驱动器132来控制朝气缸41送入的空气的压力。CPU101根据操作者的操作来驱动气缸41，使支撑部40的位置朝使用位置和维护位置移动。
马达驱动用驱动器133与CPU101连接。马达91～93分别与马达驱动用驱动器133连接。CPU101通过马达驱动用驱动器133使马达91～93分别以期望的旋转速度旋转。加热器143与CPU101连接。加热器143配置于贮存室26、泵壳体31和支撑部40。CPU101根据由温度传感器113检测出的温度来控制加热器143的接通/断开，从而将粘接剂的温度调整为期望的温度。
送出风扇驱动器134和吸引风扇驱动器135分别与CPU101连接。送出风扇驱动器134与送出风扇56连接。CPU101通过送出风扇驱动器134来控制送出风扇56的马达的动作。送出风扇驱动器134将表示送出风扇56的动作状态的信号发送给CPU101。吸引风扇驱动器135与吸引风扇62连接。CPU101通过吸引风扇驱动器135来控制吸引风扇62的马达的动作。吸引风扇驱动器135将表示吸引风扇62的动作状态的信号发送给CPU101。CPU101根据由第一气体传感器53和第二气体传感器54检测出的气体浓度、送出风扇56和吸引风扇62的动作状态(是否正常动作)，来控制送出风扇56和吸引风扇62的动作。
参照图6，对由布粘接装置1进行的气体除去控制处理进行说明。气体除去控制处理是根据气体浓度来控制送出风扇56和吸引风扇62的动作以及粘接剂排出的停止、允许的处理。操作者接通布粘接装置1的电源时，CPU101根据存储在ROM102内的程序来执行气体除去控制处理。
如图6所示，CPU101以“小”输出来驱动送出风扇56(S1)。CPU101以“小”输出来驱动吸引风扇62(S2)。CPU101从送出风扇驱动器134和吸引风扇驱动器135接收信号。CPU101根据接收到的信号来判断送出风扇56和吸引风扇62的动作是否均正常(S3)。送出风扇56和吸引风扇62的动作均正常时(S3：是)，CPU101判断由第一气体传感器53检测出的气体浓度(第一浓度)和由第二气体传感器54检测出的气体浓度(第二浓度)中的至少一方是否为第一阈值以上(S4)。第一阈值是比后述的第二阈值大的值。第一阈值是为了判断是否停止粘接剂从喷嘴45的排出而使用的值。
第一浓度和第二浓度两者均比第一阈值低时(S4：否)，CPU101判断第一浓度和第二浓度中的至少一方是否为第二阈值以上(S5)。第二阈值是为了判断将送出风扇56和吸引风扇62的输出设为“小”还是“大”而使用的值。
第一浓度和第二浓度两者均比第二阈值低时(S5：否)，CPU101返回步骤S1的处理。CPU101将送出风扇56和吸引风扇62的输出维持在“小”的状态。若气体浓度上升，第一浓度和第二浓度中的至少一方为第二阈值以上且比第一阈值低(S5：是)，则CPU101将送出风扇56的输出设为“大”(S6)，并将吸引风扇的输出设为“大”(S7)。CPU101返回步骤S3的处理。若气体浓度下降，第一浓度和第二浓度两者均比第二阈值低(S5：否)，则CPU101使送出风扇56和吸引风扇62的输出均返回“小”(S1、S2)。布粘接装置1以第二阈值为基准，在“大”与“小”之间切换送出风扇56和吸引风扇62的输出。因此，布粘接装置1能以简便的处理高效地除去气体。
送出风扇56和吸引风扇62中的至少一方的动作不正常时(S3：否)以及第一浓度和第二浓度中的至少一方成为第一阈值以上时(S4：是)，CPU101停止粘接剂的排出(S11)。具体而言，CPU101通过停止第一马达91来停止齿轮泵35的驱动。其结果是，粘接剂从喷嘴45的排出停止。即使将送出机构和吸引机构的输出设为“大”时气体浓度也较高时，布粘接装置1停止粘接剂的供给。因此，布粘接装置1能更可靠地将气体浓度抑制成较低。CPU101使表示气体浓度较高的警告消息显示于液晶显示部141(S12)。CPU101判断是否有解除警告的指示(S13)。若没有解除指示(S13：否)，则CPU101在停止粘接剂排出的状态下继续输出警告消息(S12)。
操作者操作键112、输入解除警告的指示时(S13：是)，CPU101再次判断第一浓度和第二浓度中的至少一方是否为第一阈值以上(S14)。若第一浓度和第二浓度中的至少一方为第一阈值以上(S14：是)，则CPU101返回步骤S12的处理，继续输出警告消息。若第一浓度和第二浓度两者均比第一阈值低(S14：否)，则CPU101解除对粘接剂排出的停止，允许排出(S15)。具体而言，CPU101驱动第一马达91。CPU101将液晶显示部141中显示的警告消息清除，解除警告(S16)，并返回步骤S1的处理。另外，送出风扇56和吸引风扇62在为“小”输出时，送风力、吸引力比为“大”输出时小。
如上所述，本实施方式的布粘接装置1包括盖部件51。盖部件51防止气体从喷嘴45侧朝操作者侧直接流动。因此，即使在粘接剂产生气体时，布粘接装置1也能以简易的结构容易地降低朝操作者侧流动的气体的量。布粘接装置1包括从操作者侧朝喷嘴45侧送出空气的送出风扇56。布粘接装置1能根据粘接剂产生的气体的浓度来控制送出风扇56的动作。因此，布粘接装置1能根据气体浓度高效地除去气体。布粘接装置1还包括吸引排出气体的吸引机构60，因此，能更可靠地除去气体。布粘接装置1能根据气体浓度来控制吸引机构60的动作。因此，布粘接装置1能高效地除去气体。
在检测出的气体浓度为第一阈值以上时，布粘接装置1停止粘接剂从喷嘴45的排出。因此，布粘接装置1能将气体浓度抑制成较低。送出风扇56未正常动作时，布粘接装置1停止粘接剂从喷嘴45的排出。送出风扇56未正常动作时，不产生气体。因此，布粘接装置1能更可靠地将气体浓度抑制成较低。
在上述实施方式中，齿轮泵35、第一马达91和CPU101相当于本发明的“供给部”。送出风扇56相当于“送出机构”。第一气体传感器53和第二气体传感器54相当于“浓度检测部”。执行图6的步骤S1和S6的CPU101作为“送出控制部”起作用。
吸引机构60相当于本发明的“吸引机构”。执行图6的步骤S2和S7的CPU101作为“吸引控制部”起作用。在图6的步骤S3中检测送出风扇56是否正常动作的CPU101作为“动作检测部”起作用。CPU101为了判断设为“小”还是“大”而使用的第二阈值相当于“第一规定值”。CPU101为了判断是否停止粘接剂的排出而使用的第一阈值相当于“第二规定值”。
上述实施方式所示的结构和处理只是例示，可进行各种变更。例如，上述实施方式的盖部件51利用螺钉52固定于支撑部40。但是，盖部件51的结构可适当变更。例如，盖部件51也可与支撑部40一体形成。盖部件51与支撑部40一体形成时，能可靠地减小气体朝操作者侧流动的可能性。
布粘接装置1也可对盖部件51是否正常安装于支撑部40进行检测。布粘接装置1也可在未正常安装盖部件51时停止粘接剂的排出。例如，支撑部40具有槽，盖部件51具有插入槽内的导电性的销。电流只在将销插入槽内时、也就是将盖部件51安装于支撑部时导通。CPU101判断电流是否导通。若电流未导通，则CPU101停止粘接剂的排出。布粘接装置1也可利用设置于支撑部40的微动开关等来检测盖部件51的安装状态。
盖部件51的形状可进行变更。例如，盖部件也可以是包括收容气体的空间的箱状。箱状的盖部件也可配置成从上部围住喷嘴45并将其覆盖。此例的盖部件能在粘接剂产生的气体相对于空气的比重较小时收集气体。因此，此例的盖部件能减小气体朝操作者侧流动的可能性。此例的盖部件中，若在上部设置开口部并连接吸引机构60的管61的前端，则能更高效地除去气体。
送出风扇56和吸引风扇62的控制方法可进行变更。为了更可靠地除去气体，较为理想的是送出风扇56和吸引风扇62始终动作。但是，例如也可以这样：送出风扇56在布粘接装置1的电源接通时动作，吸引风扇62在气体浓度成为规定值以上后与送出风扇56一起动作。上述实施方式中，送出风扇56和吸引风扇62的输出为“小”和“大”这两个等级。但是，输出的等级和用于确定输出的气体浓度的阈值也可有很多。变更送出风扇56和吸引风扇62的输出的时刻也可彼此不同。
用于确定送出风扇56和吸引风扇62的输出的气体浓度的阈值和用于确定是否停止粘接剂排出的气体浓度的阈值也可根据第一气体传感器53和第二气体传感器54各自的检测结果分别设定。通常，第一气体传感器53检测出的气体浓度比位于盖部件51背面侧的第二气体传感器54检测出的浓度低。因此，通过将与第一气体传感器53对应的阈值设定成比与第二气体传感器54对应的阈值低，能更适当地控制布粘接装置1的动作。气体传感器的数目不局限于两个。例如，盖部件51也可只包括位于操作者侧的第一气体传感器53。气体传感器的配置位置可适当变更。
吸引机构60的结构可进行变更。例如，吸引装置也可配置于布粘接装置1的外部。上述情况下，吸引装置包括管，该管配置于喷嘴45的附近。一个吸引装置也可对多个布粘接装置1吸引气体。布粘接装置1也可不包括吸引机构。也就是说，布粘接装置1也可只包括送出风扇56。
在步骤S11中，CPU101也可同时停止第二马达92、第三马达93。此时，在步骤S15中，CPU101同时驱动第二马达92、第三马达93。
