Description
本發明整體而言係關於用於施配熱熔黏膠之系統。更明確而言,本發明係關於將固態黏膠顆粒饋送至用於施配熱熔黏膠之一系統中。 The present invention generally relates to systems for dispensing hot melt adhesives. More specifically, the present invention relates to feeding solid adhesive particles into a system for dispensing a hot melt adhesive.
熱熔物施配系統一般係用於製造組裝線中自動地施配用於構造包裝材料(諸如盒、紙箱等等)中之黏膠。熱熔物施配系統習知上包括一材料儲槽、加熱元件、一幫浦及一施配器。可使用一加熱元件在該儲槽中熔化固態聚合物顆粒,此後藉由該幫浦將該等顆粒供應至該施配器。由於若熔化顆粒被允許冷卻,則其將重新固化成固體形式,因此自該儲槽至該施配器必須維持該等熔化顆粒之溫度。此一般需要於該儲槽、該幫浦及該施配器中放置加熱元件,此外需要加熱連接此等組件之任何管件或軟管。此外,習知熱熔物施配系統一般使用容積大之儲槽,使得可延長容納在該等儲槽中之顆粒熔化之後之施配時段。然而,該儲槽內之顆粒體積大則完全熔化需要相當長時間,此增加該系統之啟動時間。例如,一典型之儲槽包含內襯於一矩形、重力饋送儲槽之壁之複數個加熱元件,使得沿該等壁之熔化顆粒阻止該等加熱元件有效地熔化該容器之中心之顆粒。此等儲槽中之顆粒需要更長之時間熔化導致由於黏膠熱曝露時間長而增加「焦化」(charring)或發黑之可能性。 Hot melt dispensing systems are typically used in manufacturing assembly lines to automatically dispense adhesives for use in constructing packaging materials such as boxes, cartons, and the like. The hot melt dispensing system conventionally includes a material reservoir, a heating element, a pump, and a dispenser. A solid heating element can be used to melt the solid polymer particles in the reservoir, after which the particles are supplied to the dispenser by the pump. Since the molten particles will re-solidify into a solid form if they are allowed to cool, the temperature of the molten particles must be maintained from the reservoir to the dispenser. This generally requires the placement of heating elements in the reservoir, the pump, and the dispenser, and in addition to heating any tubing or hoses that connect the components. In addition, conventional hot melt dispensing systems typically use a reservoir having a large volume such that the dispensing period after the particles contained in the reservoirs are melted can be extended. However, it takes a considerable amount of time for the particles in the tank to be completely melted, which increases the startup time of the system. For example, a typical reservoir includes a plurality of heating elements lined into a rectangular, gravity-fed reservoir wall such that the molten particles along the walls prevent the heating elements from effectively melting the particles in the center of the container. The particles in such tanks take longer to melt, increasing the likelihood of "charring" or blackening due to the long exposure time of the glue.
根據本發明,一熱熔物施配系統包含,一容器,其用於儲存黏膠顆粒;一熔化系統,其用於對黏膠顆粒加熱而使之熔化成液體;及一饋送系統,其將該容器連接至該熔化系統。該饋送系統包含一可逆之流體引導器,其具有用於將黏膠顆粒自該容器饋送至該熔化系統之一第一位置。該可逆之流體引導器亦具有用於使黏膠顆粒自該饋送系統返回該容器之一第二位置。 According to the present invention, a hot melt dispensing system includes a container for storing adhesive particles, a melting system for heating the adhesive particles to melt into a liquid, and a feeding system that will The container is connected to the melting system.

饋送總成22係一饋送系統,其經流體地連接至容器20之顆粒出口50,以將黏膠顆粒52自容器20運輸至熔化系統30(如圖1中所示)。饋送總成22之入口28為真空總成24之一顆粒入口。真空總成24係用於引導氣流及黏膠顆粒流52之一流體引導器。在所圖解之實施例中,真空總成24係一文氏管真空總成,其具有文氏管進氣口54及文氏管出氣口56。配送通路58將文氏管進氣口54流體地連接至文氏管出氣口56,其等相互形成角度,以透過饋送總成22將空氣導向下游。來自空氣軟管35B之空氣流經文氏管進氣口54、流經配送通路58且以一角度流經文氏管出氣口56。真空總成24在饋送總成22中產生一真空,以將黏膠顆粒52吸取至真空總成24中,且所得之氣流繼續推動黏膠顆粒52通過饋送軟管26。由真空總成24產生之真空係饋送總成22中之一低壓區,其用於引導來自容器20之黏膠顆粒流。在所圖解之實施例中,真空總成24為一可逆之流體引導器,如下文將參考圖3A及圖3B進一步描述。 The feed assembly 22 is a feed system fluidly coupled to the particle outlet 50 of the container 20 to transport the adhesive particles 52 from the container 20 to the melting system 30 (as shown in Figure 1). The inlet 28 of the feed assembly 22 is a particle inlet for the vacuum assembly 24. The vacuum assembly 24 is used to direct one of the airflow and fluid flow of the glue particles 52. In the illustrated embodiment, the vacuum assembly 24 is a venturi vacuum assembly having a venturi inlet 54 and a venturi outlet 56. The distribution passage 58 fluidly connects the venturi inlet 54 to the venturi outlet 56, which are angled to each other to direct air downstream through the feed assembly 22. Air from air hose 35B flows through venturi inlet 54, through distribution passage 58 and through venturi outlet 56 at an angle. The vacuum assembly 24 creates a vacuum in the feed assembly 22 to draw the viscous particles 52 into the vacuum assembly 24, and the resulting gas stream continues to push the viscous particles 52 through the feed hose 26. The vacuum system produced by vacuum assembly 24 feeds a low pressure zone in assembly 22 for directing the flow of adhesive particles from container 20. In the illustrated embodiment, vacuum assembly 24 is a reversible fluid guide, as will be further described below with reference to Figures 3A and 3B.
圖3A係作為饋送總成22之一部分之真空總成24之位於一第一位置之一示意性側視圖。真空總成24包含噴嘴60及把手62。噴嘴60包含噴嘴本體64,其係一實質上曲面本體,其界定文氏管出氣口56、配送通路58及顆粒通路66。配送通路58係圍繞噴嘴本體64延伸之一通道。配送通路58係與文氏管進氣口54對準,以將文氏管空氣配送至文氏管出氣口56,此於一可選擇方向上將文氏管氣流引導至真空總成24中。文氏管出氣口56係圍繞顆粒通路66徑向向外且圓周地定位。顆粒通路66包含顆粒通路入口68及顆粒通路出口70。文氏管出氣口56係於顆粒通路66之最為鄰近顆粒通路出口70之一端之附近。文氏管空氣流出文氏管出氣口56在顆粒通路出口70之下游之真空總成24中產生一低壓區,以在自顆粒通路入口68至顆粒通路出口70之一方向上通過顆粒通路66引導氣流及黏膠顆粒流(如圖2中所示)。當真空總成24係位於該第一位置時,真空總成24產生一吸力,以自容器20將黏膠顆粒52吸取至真空總成24,且接著在一第一方向上自真空總成24將黏膠顆粒52吹動至熔化系統30(如圖1中所示)。 3A is a schematic side elevational view of the vacuum assembly 24 as part of the feed assembly 22 in a first position. The vacuum assembly 24 includes a nozzle 60 and a handle 62. Nozzle 60 includes a nozzle body 64 that is a substantially curved body that defines a venturi outlet 56, a dispensing passage 58, and a particulate passage 66. The dispensing passage 58 extends through one of the passages of the nozzle body 64. The distribution passage 58 is aligned with the venturi inlet 54 to distribute the venturi air to the venturi outlet 56, which directs the venturi flow into the vacuum assembly 24 in a selectable direction. The venturi outlet 56 is positioned radially outwardly and circumferentially about the particle passage 66. The particle passage 66 includes a particulate passage inlet 68 and a particulate passage outlet 70. The venturi outlet 56 is located adjacent one of the most adjacent particle passage outlets 70 of the particle passage 66. The venturi air outflow venturi outlet 56 creates a low pressure zone in the vacuum assembly 24 downstream of the particulate passage outlet 70 to direct the flow through the particulate passage 66 in one direction from the particulate passage inlet 68 to the particulate passage outlet 70. And the flow of viscose particles (as shown in Figure 2). When the vacuum assembly 24 is in the first position, the vacuum assembly 24 generates a suction to draw the adhesive particles 52 from the container 20 to the vacuum assembly 24, and then in a first direction from the vacuum assembly 24 The viscose particles 52 are blown to the melting system 30 (as shown in Figure 1).
噴嘴60係能夠在第一位置與第二位置之間移動之一可逆之噴嘴。如圖3A中所圖解,噴嘴60係位於一第一位置,以沿饋送軟管26將氣流導向熔化系統30。把手62係經由軸桿72連接至噴嘴60,以使噴嘴60在第一位置與第二位置之間移動。軸桿72係由軸承74支撐,以允許把手62、軸桿72及噴嘴60圍繞軸桿72之一軸線而相對於真空總成殼體76樞 轉。噴嘴60係可樞轉地定位於真空總成殼體76內之一袋中。在所圖解之實施例中,文氏管進氣口54延伸至真空總成殼體76中且與軸桿72之軸線實質上對準。 The nozzle 60 is configured to move a reversible nozzle between the first position and the second position. As illustrated in Figure 3A, the nozzle 60 is in a first position to direct airflow along the feed hose 26 to the melting system 30. Handle 62 is coupled to nozzle 60 via shaft 72 to move nozzle 60 between a first position and a second position. The shaft 72 is supported by bearings 74 to allow the handle 62, the shaft 72 and the nozzle 60 to pivot about the axis of the shaft 72 relative to the vacuum assembly housing 76. turn. The nozzle 60 is pivotally positioned in a pocket within the vacuum assembly housing 76. In the illustrated embodiment, the venturi inlet 54 extends into the vacuum assembly housing 76 and is substantially aligned with the axis of the shaft 72.
在系統10之正常操作期間(如圖1中所示),真空總成24之噴嘴60可位於該第一位置,以在該第一方向上引導氣流。在該第一位置,真空總成24可通過饋送總成22自容器20將黏膠顆粒引導至熔化總成30。在系統10已經在一段時間內完成正常操作之後,系統10可暫停或者關閉。在正常操作時段之間,饋送總成22中可能仍存在殘留之黏膠顆粒52。當系統10再次啟動時,可藉由真空總成24將該等黏膠顆粒52吹動至熔化總成30,以由熔化總成30熔化。 During normal operation of system 10 (as shown in FIG. 1), nozzle 60 of vacuum assembly 24 can be positioned at the first position to direct airflow in the first direction. In this first position, the vacuum assembly 24 can direct the adhesive particles from the container 20 to the melting assembly 30 through the feed assembly 22. System 10 may be suspended or turned off after system 10 has completed normal operations for a period of time. Between the normal operating periods, residual adhesive particles 52 may still be present in the feed assembly 22. When the system 10 is again activated, the viscose particles 52 can be blown to the melting assembly 30 by the vacuum assembly 24 to be melted by the melting assembly 30.
在一些應用中,系統10可用於針對不同應用之不同類型之黏膠顆粒52。在正常操作時段之間,可斷開容器20且用容納不同類型之黏膠顆粒之一替換容器予以更換。在此等情形下,需要移除饋送總成22中之殘留黏膠顆粒52,以避免(殘留黏膠顆粒)污染用於不同操作中之新的黏膠顆粒。 In some applications, system 10 can be used for different types of adhesive particles 52 for different applications. Between normal operating periods, the container 20 can be disconnected and replaced with a container that accommodates one of the different types of adhesive particles. In such cases, the residual viscose particles 52 in the feed assembly 22 need to be removed to avoid (residual adhesive particles) contaminating new viscose particles for use in different operations.
圖3B係真空總成24在噴嘴60係位於該第二位置時之一示意性側視圖。在該第二位置,文氏管出氣口56及顆粒通路66係在與該第一方向相反之一第二方向上指向容器20。在該第二位置,文氏管空氣流出文氏管出氣口56造成顆粒通路出口70之下游之真空總成24中產生一低壓區,以引導空氣流及黏膠顆粒流52(如圖2中所示)自饋送軟管26在第二方向上通過顆粒通路66、通過顆粒通路入口68、通過顆粒通路出口70且進入容器20中。當真空總成24係位於該第二位 置時,真空總成24產生一吸力,以自饋送軟管26將黏膠顆粒52吸取至真空總成24,且接著自真空總成24將黏膠顆粒52吹動至容器20。因此,真空總成24使黏膠顆粒52自總成22返回容器20。此為在更換容器20之前自饋送總成22移除黏膠顆粒52之一相對便利之方式。在黏膠顆粒52已經返回容器20之後,可用容納不同黏膠顆粒之一替換容器來更換容器20。在一些實施例中,容器20可包含一關閉閥(圖中未繪示)或用於閉合顆粒出口50之其他機構。 3B is a schematic side view of the vacuum assembly 24 when the nozzle 60 is in the second position. In the second position, the venturi outlet 56 and the particulate passage 66 are directed toward the container 20 in a second direction opposite the first direction. In the second position, the venturi air flows out of the venturi outlet 56 to create a low pressure zone in the vacuum assembly 24 downstream of the particulate passage outlet 70 to direct the air flow and the flow of the viscous particles 52 (see Figure 2). The self-feeding hose 26 passes through the particle passage 66 in the second direction, through the particle passage inlet 68, through the particle passage outlet 70, and into the container 20. When the vacuum assembly 24 is in the second position At the time, the vacuum assembly 24 produces a suction to draw the adhesive particles 52 from the feed hose 26 to the vacuum assembly 24, and then the adhesive particles 52 are blown from the vacuum assembly 24 to the container 20. Thus, the vacuum assembly 24 returns the adhesive particles 52 from the assembly 22 to the container 20. This is a relatively convenient way to remove one of the adhesive particles 52 from the feed assembly 22 prior to replacing the container 20. After the adhesive particles 52 have been returned to the container 20, the container 20 can be replaced by replacing the container with one of the different adhesive particles. In some embodiments, the container 20 can include a closure valve (not shown) or other mechanism for closing the particle outlet 50.
把手62允許使用者視需要手動地使真空總成24在第一位置與第二位置之間移動。在替代性實施例中,在真空總成24中,可省略把手62且真空總成24可自動地或者經由適於使真空總成24中之氣流之方向逆轉之另一機構來逆轉方向。 The handle 62 allows the user to manually move the vacuum assembly 24 between the first position and the second position as needed. In an alternative embodiment, in the vacuum assembly 24, the handle 62 can be omitted and the vacuum assembly 24 can be reversed automatically or via another mechanism adapted to reverse the direction of the airflow in the vacuum assembly 24.
