Description

纸容器发泡装置 技术领域
本发明有关于一种纸容器发泡装置。
背景技术
一般已知的隔热抛弃式容器常用于盛装热饮或热汤等，而其隔热层 通常是以发泡层为主， 于成型的纸容器外壁涂布发泡材料， 再施以高温 使其发泡膨胀。
目前已知的技术中，以输送带方式承载复数个涂布发泡材料的纸容 器通过加热装置来进行发泡，发泡、冷却完成后再集中收集堆叠。然而， 此类结构中， 加热装置所产生的热量并无法均匀地分布， 也就是说， 离 加热装置远的地方温度较低， 而离加热装置较近的地方温度较高， 可能 造成同一纸容器中其中一侧过热而过度发泡甚至破泡的情形，但另一侧 却温度不足而发泡不完整，进而影响良率， 更由于加热装置必定仅位于 加热空间中的一特定位置， 热量仅靠空气传导而更难传递到较远处， 使 得温度差异过大， 不利于发泡均匀。
发明内容
本发明的主要目的在于提供一种纸容器发泡装置，能使同一纸容器 上受热平均， 还能提升加热速率与使热量分布更为均匀。
为达成上述目的，本发明提供一种纸容器发泡装置， 用以将至少一 未发泡纸容器的发泡材料进行加热发泡，该纸容器发泡加热装置包含一 加热部与至少一承座。
该加热部具有一加热装置与一气流导引装置，该气流导引装置能将 该加热装置产生的热量导向一特定方向以将该未发泡纸容器进行加热 发泡； 该承座包含一转动机构， 该未发泡纸容器能被该承座承载并于该 加热部被该转动机构转动。
进一步地，
所述加热装置为一加热板， 设置于所述加热部的顶部，所述气流导 引装置包含至少一供气口与至少一回气口，该供气口位于所述加热部的 顶部， 该回气口位于所述加热部的底部， 该供气口能输出气流， 而该回 气口能将气流吸出所述加热部以将所述加热装置产生的热量往下导弓 I， 以便于将该未发泡纸容器进行加热发泡。
包含复数个间隔排列的承座，所述气流导引装置包含复数个供气口 与至少一回气口， 各该供气口位置对应于其中两相邻的承座之间。
所述加热装置下方还具有一挡板，用以阻挡所述加热装置产生的热 直接往下辐射传递。
所述供气口与所述回气口以一管道相连通而形成一气流循环系统。 以此，通过转动的承座使纸容器于发泡过程中持续转动， 而能使纸 容器各处的发泡材料均匀受热， 进而提升良率， 再者， 气流导引装置还 能携带加热装置所产生的热量至各处，进而提升发泡速率与发泡均匀程 度。

具体实施方式
以下仅以实施例说明本发明可能的实施例，然并非用以限制本发明 所欲保护的范畴， 事先声明。
请参考图 1至图 5， 本发明提供一种纸容器发泡装置， 用以将复数 个未发泡纸容器 80的发泡材料进行加热发泡， 其中该发泡材料涂布于 各未发泡纸容器 80的外壁面， 于本发明的主要实施例中， 纸容器发泡 装置包含一进料部 10、 一加热部 20、 一冷却部 30、 一收料部 40与复 数个可移动的载物座 50， 其中进料部 10、 加热部 20、 冷却部 30与收 料部 40依序连续排列于一机具中，该些载物座 50即位于该机具中而能 依序通过进料部 10、 加热部 20、 冷却部 30与收料部 40。
各载物座 50供承载未发泡纸容器 80且载物座 50沿其移动的方向 间隔依序排列， 各载物座 50包含一移动机构与复数个承座 51， 承座 51 沿一与载物座 50移动方向垂直的方向排列，各承座 51包含一转动机构， 当各载物座 50经移动机构移动时，转动机构使承座 51绕一预定转轴转 动， 该预定转轴与载物座 50的移动方向垂直。 更详细来说， 该移动机 构包含一炼条输送结构 70， 载物座 50固定于炼条输送结构 70而能被 炼条输送结构 70携带往一预定方向移动，其中炼条输送结构 70延伸至 进料部 10、 加热部 20、 冷却部 30与收料部 40并呈循环状， 以将载物 座 50 自进料部 10往加热部 20、 冷却部 30与收料部 40输送并绕回进 料部 10。另一方面，本发明提供的纸容器发泡装置具有复数个轨道 60， 各承座 51的转动机构包含一与承座 51同轴设置的齿轮 52， 齿轮 52与 其中一轨道 60彼此抵顶， 当移动机构带动载物座 50移动时， 承座 51 因齿轮 52与轨道 60之间的摩擦力而转动， 更明确来说， 各轨道 60位 于任两相邻的承座 51之间而相对两侧分别具有一抵顶面 61，各轨道 60 两侧的齿轮 52分别抵顶于两抵顶面 61。 此外， 各承座 51 的顶部具有 一外径较大的撑置部 511， 承座 51能伸入未发泡纸容器 80内部， 撑置 部 511顶撑未发泡纸容器 80的底部， 使未发泡纸容器 80被撑起， 未发 泡纸容器 80的开口与外界连通而呈开放状， 以利热气进入未发泡纸容 器 80的内部而助于加快发泡速度， 还能使热气同时自内部对较内层的 发泡材料进行加热发泡，避免较外层的发泡材料已过度发泡但较内层的 发泡材料却发泡不完全的情形。
进料部 10包含复数个进料管 11， 该些进料管 11依序纵向且平行 地排列， 各进料管 11底端形成一进料口 111， 该些进料管 11供容纳未 发泡纸容器 80并将未发泡纸容器 80往进料口 111输送，其中各未发泡 纸容器 80的开口朝下而底部朝上， 另外， 进料口 111排列方式与承座 51的排列方式相对应， 也就是说， 各进料口 111对应其中一承座 51， 当载物座 50移动至进料部 10时， 承座 51分别承接进料口 111输出的 未发泡纸容器 80。
加热部 20具有至少一加热装置 21与至少一气流导引装置，加热装 置 21较佳地为设置于加热部 20顶部的一加热板，气流导引装置包含复 数个供气口 22与至少一回气口 23，各供气口 22位于加热部 20的顶部， 回气口 23位于加热部 20的底部，供气口 22能对加热部 20输出气流（例 如喷嘴喷出气流）， 而回气口 23能将气流自加热部 20吸出以将加热装 置 21产生的热量往下导引， 较佳地， 供气口 22与回气口 23以一外部 管道相连通而形成一气流循环系统， 此外， 加热装置 21下方还具有一 挡板 24， 用以阻挡加热装置 21产生的热直接往下辐射传递。 特别要说 明的是， 当携带未发泡纸容器 80的载物座 50进入加热部 20， 各供气 口 22的位置恰对应于其中两相邻的承座 51之间， 使得供气口 22所喷 出的气流能携带热量到达该两相邻的承座 51上所承载的未发泡纸容器 80的外壁， 以确实将发泡材料进行加热发泡。
冷却部 30用以将已加热发泡完成的纸容器 80'冷却以利后续收料、 包装等制程， 也就是说， 当携带已加热发泡完成的纸容器 80'的载物座 50进入冷却部 30， 冷却部 30即对该些纸容器 80'进行冷却。
收料部 40包含复数个收料管 41， 该些收料管 41依序纵向且平行 排列， 各收料管 41底端形成一收料口 41 1， 该些收料口 411分别对承 座 51上已发泡完成的纸容器 80'进行回收， 并经由收料管 41往上输送 以进行后续包装作业。 其中收料口 411与收料管 41的排列方式与承座 51 的排列方式相对应， 当载物座 50携带已发泡完成的纸容器 80'入收 料部 40， 收料口 411与承座 51位置分别相对应， 使各收料口 411能分 别对其中一承座 51上的纸容器 80'进行回收。 换句话说， 纸容器 80'所 对应的进料口 1 11与收料口 411排序一致而彼此相对应，使同一群组的 纸容器 80'能被同一进料口 111输出、被同一位置的承座 51携带并进行 发泡、 以及被同一收料口 411回收， 制程前后均维持同一群组而不会混 乱。
实际操作时， 如图 6搭配图 2所示， 使用者可于各进料管 11中置 入同一群组的未发泡纸容器 80、 80a (例如同样大小、 同样颜色、 同一 样式或同一客户订单的商品），经由进料口、承座与收料口的彼此对应， 此同一群组的各未发泡纸容器 80、 80a能被同一位置的承座 51携带并 发泡， 再被同一收料口 411回收、 叠合甚至进行包装， 如此一来， 如图 6搭配图 2所示， 不同群组的纸容器能通过放置于不同的进料管 11而 可同时进行输送、 发泡、 冷却以及回收， 且不会与其他群组的纸容器彼 此混杂， 仅有同一群组的纸容器会被回收、 堆叠在一起， 相当利于后续 加工、 包装与分类的作业， 还可应用于小量制作， 也就是说， 当每个进 料管所置入的纸容器均分属不同群组，即可以短时间进行多样式的小量 制作。
至于本发明中的气流导引装置能有效地将加热装置所产生的热量 快速且均匀地往下传递， 避免局部过于高温以及局部温度不足的问题， 进而避免受热较多区域发泡过度而破泡、甚至高温穿透纸容器破坏内层 淋膜层、 而受热较少区域又发泡不完全的情形； 再者， 由于气流导引装 置的供气口恰好对准于两相邻的承座之间， 也就是说，供气口喷出的气 流携带热量后直达该两相邻承座的外壁， 加热效率因此提高； 甚至， 由 于气流朝下流动， 能使纸容器更为牢靠地撑置在承座上， 不易翻覆而影 响良率。
另一方面， 由于承座于移动的同时进行自转， 使得所承载的纸容器 外壁可被均匀受热， 即使加热部的加热仍未能均匀，承座仍能经由自转 降低纸容器外壁各处发泡程度的差异。
此外，承座能撑高纸容器，使纸容器的开口与外界连通而呈开放状， 也就是说， 热气能进入纸容器内部， 内外同时加热而可加速发泡、 并使 加热更为均匀。
综上所述，本发明具有复数个间隔排列的载物座持续地通过炼条输 送结构往前移动， 而能达到快速、 大量的生产， 且不同群组的产物不会 彼此混杂，又通过可自转与撑高的承座以及携带热风的高速气流提高加 热速率与均匀度， 大幅提高良率、 产量与生产效率， 极具进步之效。
以上所述是本发明的较佳实施例及其所运用的技术原理，对于本领 域的技术人员来说，在不背离本发明的精神和范围的情况下，任何基于 本发明技术方案基础上的等效变换、简单替换等显而易见的改变， 均属 于本发明保护范围之内。
