Description
本發明係有關於一種紙容器發泡裝置。 The present invention relates to a paper container foaming device.
一般習知的隔熱拋棄式容器常用於盛裝熱飲或熱湯等，而其隔熱層通常是以發泡層為主，係於成型的紙容器外壁塗布發泡材料，再施以高溫使其發泡膨脹。 Conventionally known heat-insulating disposable containers are often used for hot drinks or hot soups, and the heat-insulating layer is usually a foamed layer, which is coated with a foamed material on the outer wall of the formed paper container, and then applied at a high temperature. Bubble expansion.
目前已知的技術中，係以輸送帶方式承載複數個塗布發泡材料的紙容器通過加熱裝置來進行發泡，發泡、冷卻完成後再集中收集堆疊。然而，此類結構中，由於加熱裝置對加熱空間中各處的加熱程度並不均勻，可能造成同一紙容器中其中一側過熱而過度發泡甚至破泡的情形，但另一側卻溫度不足而發泡不完整，進而影響良率，若要施以較長時間的發泡或較高溫度的發泡，又可能使過度發泡的情形更為嚴重，甚至熱量穿越容器壁面到達內面，使內面塗覆的淋膜層受熱破壞分解，導致毒素釋出的危害。 In the currently known technology, a paper container carrying a plurality of coated foam materials in a conveyor belt manner is foamed by a heating device, and after foaming and cooling are completed, the stack is collectively collected. However, in such a structure, since the heating means does not uniformly heat the heating space, it may cause one side of the same paper container to overheat and excessively foam or even foam, but the other side is insufficient in temperature. The foaming is incomplete, which in turn affects the yield. If a longer period of foaming or higher temperature foaming is applied, the excessive foaming may be more serious, even if the heat passes through the wall of the container to reach the inner surface. The inner coating of the coating layer is decomposed by thermal damage, resulting in the release of toxins.
本發明之主要目的在於提供一種紙容器發泡裝置，能使紙容器上各處的發泡材料能均勻受熱發泡，以提升良率。 The main object of the present invention is to provide a paper container foaming device which can uniformly foam the foamed material on the paper container to improve the yield.

The unfoamed paper containers 80 are transported to the feed ports 111, wherein the openings of the unfoamed paper containers 80 face downward and the bottom faces upwards. The arrangement of the nozzles 111 corresponds to the arrangement of the sockets 51, that is, each of the inlets 111 corresponds to one of the sockets 51, and when the carrier 50 is moved to the feeding portion 10, The sockets 51 respectively receive the unfoamed paper containers 80 output from the feed ports 111.
該加熱部20具有至少一加熱裝置21與至少一氣流導引裝置，該加熱裝置21較佳地為設置於該加熱部20頂部的一加熱板，該氣流導引裝置包含複數個供氣口22與至少一回氣口23，各該供氣口22位於該加熱部20之頂部，該回氣口23位於該加熱部20之底部，該供氣口22能對該加熱部20輸出氣流(例如噴嘴噴出氣流)，而該回氣口23能將氣流自加熱部20吸出以將該加熱裝置21產生的熱量往下導引，較佳地，該些供氣口22與該回氣口23以一外部管道相連通而形成一氣流循環系統，此外，該加熱裝置21下方更具有一擋板24，用以阻擋該加熱裝置21產生的熱直接往下輻射傳遞。特別要說明的是，當攜帶未發泡紙容器80的載物座50進入該加熱部20，各該供氣口22的位置恰對應於其中二相鄰的承座51之間，使得該供氣口22所噴出的氣流能攜帶熱量到達該二相鄰的承座51上所承載之 未發泡紙容器80的外壁，以確實將發泡材料進行加熱發泡。 The heating unit 20 has at least one heating device 21 and at least one airflow guiding device. The heating device 21 is preferably a heating plate disposed on the top of the heating portion 20, and the airflow guiding device includes a plurality of air supply ports 22 And at least one gas return port 23, each of the gas supply ports 22 is located at the top of the heating portion 20, and the gas return port 23 is located at the bottom of the heating portion 20, and the gas supply port 22 can output an air flow to the heating portion 20 (for example, nozzle ejection The air return port 23 can suck the air flow from the heating portion 20 to guide the heat generated by the heating device 21 downward. Preferably, the air supply ports 22 are connected to the air return port 23 by an external pipe. A gas circulation system is formed in the air. In addition, a baffle 24 is further disposed under the heating device 21 to block the heat generated by the heating device 21 from directly radiating downward. In particular, when the carrier 50 carrying the unfoamed paper container 80 enters the heating portion 20, the position of each of the air supply ports 22 corresponds to between two adjacent sockets 51, so that the supply The airflow from the port 22 can carry heat to the two adjacent sockets 51. The outer wall of the unfoamed paper container 80 is heated and foamed by the foaming material.
該冷卻部30係用以將已加熱發泡完成的紙容器80'冷卻以利後續收料、包裝等製程，也就是說，當攜帶已加熱發泡完成的紙容器80'的載物座50進入該冷卻部30，該冷卻部30即對該些紙容器80'進行冷卻。 The cooling portion 30 is used for cooling the paper container 80' which has been heated and foamed to facilitate subsequent processes such as receiving, packaging, etc., that is, carrying the carrier 50 of the paper container 80' which has been heated and foamed. The cooling unit 30 enters the cooling unit 30, that is, the paper containers 80' are cooled.
該收料部40包含複數個收料管41，該些收料管41依序縱向且平行排列，各該收料管41底端形成一收料口411，該些收料口411分別對該些承座51上已發泡完成的紙容器80'進行回收，並經由該些收料管41往上輸送以進行後續包裝作業。其中該些收料口411與該些收料管41的排列方式與該些承座51的排列方式相對應，當該載物座50攜帶該些已發泡完成的紙容器80'入該收料部40，該些收料口411與該些承座51位置分別相對應，使各收料口411能分別對其中一承座51上的紙容器80'進行回收。換句話說，該些紙容器80所對應的進料口111與收料口411排序一致而彼此相對應，使同一群組的紙容器80'能被同一進料口111輸出、被同一位置的承座51攜帶並進行發泡、以及被同一收料口411回收，製程前後均維持同一群組而不會混亂。 The receiving portion 40 includes a plurality of receiving tubes 41, which are arranged longitudinally and in parallel, and a receiving port 411 is formed at the bottom end of each receiving tube 41, and the receiving ports 411 respectively The paper containers 80' which have been foamed on the sockets 51 are recovered and transported upward through the receiving tubes 41 for subsequent packaging operations. The arrangement of the receiving ports 411 and the receiving tubes 41 corresponds to the arrangement of the sockets 51. When the carrier 50 carries the foamed paper containers 80' into the collection The material receiving portion 411 corresponds to the positions of the plurality of sockets 51, so that the receiving ports 411 can respectively recover the paper containers 80' on one of the sockets 51. In other words, the feed ports 111 corresponding to the paper containers 80 are aligned with the receiving ports 411 so as to correspond to each other, so that the same group of paper containers 80' can be output by the same feed port 111 and be in the same position. The socket 51 is carried and foamed, and is recovered by the same receiving port 411, and the same group is maintained before and after the process without confusion.
實際操作時，如圖6搭配圖2所示，使用者可於各進料管11中置入同一群組的未發泡紙容器80、80a(例如同樣大小、同樣顏色、同一樣式或同一客戶訂單的商品)，經由進料口、承座與收料口的彼此對應，此同一群組的各未發泡紙容器80、80a能被同一位置的承座51攜帶並發泡，再被同一收料口411回收、疊合甚至進行包裝，如此一來，如圖6搭配圖2所示，不同群組的紙容器能藉由放置於不同的進料管11而可同時進行輸送、發泡、冷卻以及回收，且不會與其他群組的紙容器彼此混雜，僅有同 一群組的紙容器會被回收、堆疊在一起，相當利於後續加工、包裝與分類的作業，更可應用於小量製作，也就是說，當每個進料管所置入的紙容器均分屬不同群組，即可以短時間進行多樣式的小量製作。 In actual operation, as shown in FIG. 6 and FIG. 2, the user can place the same group of unfoamed paper containers 80, 80a in each feeding tube 11 (for example, the same size, the same color, the same style or the same customer). The unfilled paper containers 80, 80a of the same group can be carried and foamed by the socket 51 at the same position, and the same is received by the feed port, the socket and the receiving port. The material port 411 is recovered, stacked, and even packaged. Thus, as shown in FIG. 6 and FIG. 2, different groups of paper containers can be simultaneously transported and foamed by being placed in different feeding tubes 11. Cooling and recycling, and will not mix with other groups of paper containers, only the same A group of paper containers will be recycled and stacked together, which is quite conducive to subsequent processing, packaging and sorting operations, and can be applied to small quantities, that is, when the paper containers are placed in each feeding tube. It belongs to different groups, that is, it can make small-scale production of multiple styles in a short time.
至於本發明中的氣流導引裝置能有效地將加熱裝置所產生的熱量快速且均勻地往下傳遞，避免局部過於高溫以及局部溫度不足的問題，進而避免受熱較多區域發泡過度而破泡、甚至高溫穿透紙容器破壞內層淋膜層、而受熱較少區域又發泡不完全的情形；再者，由於氣流導引裝置的供氣口恰好對準於二相鄰的承座之間，也就是說，供氣口噴出的氣流攜帶熱量後直達該二相鄰承座的外壁，加熱效率因此提高；甚至，由於氣流朝下流動，能使紙容器更為牢靠地撐置在承座上，不易翻覆而影響良率。 The airflow guiding device in the invention can effectively transfer the heat generated by the heating device downwards quickly and uniformly, avoiding the problem of local excessively high temperature and insufficient local temperature, thereby avoiding excessive foaming and foaming in a region with more heat. Even the high temperature penetrating paper container destroys the inner laminating layer, and the less heated area is incompletely foamed; further, since the air supply port of the air guiding device is just aligned with the two adjacent seats In other words, that is, the airflow from the air supply port carries heat and reaches the outer wall of the two adjacent sockets, thereby improving the heating efficiency; even, because the airflow flows downward, the paper container can be more firmly supported on the bearing. On the seat, it is not easy to overturn and affect the yield.
另一方面，由於該承座於移動的同時進行自轉，使得所承載的紙容器外壁可被均勻受熱，即使加熱部的加熱仍未能均勻，該承座仍能經由自轉降低紙容器外壁各處發泡程度的差異。 On the other hand, since the socket rotates while moving, the outer wall of the carried paper container can be uniformly heated, and even if the heating portion is not heated uniformly, the socket can still reduce the outer wall of the paper container through the rotation. The difference in the degree of foaming.
此外，該承座能撐高紙容器，使紙容器的開口與外界連通而呈開放狀，也就是說，熱氣能進入紙容器內部，內外同時加熱而可加速發泡、並使加熱更為均勻。 In addition, the socket can support the paper container so that the opening of the paper container communicates with the outside to be open, that is, the hot air can enter the inside of the paper container, and the inside and the outside are simultaneously heated to accelerate foaming and make the heating more uniform. .
綜上所述，本發明具有複數個間隔排列的載物座持續地藉該鍊條輸送結構往前移動，而能達到快速、大量的生產，且不同群組的產物不會彼此混雜，又藉由可自轉與撐高的承座以及攜帶熱風的高速氣流提高加熱速率與均勻度，大幅提高良率、產量與生產效率，極具進步之效。 In summary, the present invention has a plurality of spaced-apart carrier holders that are continuously moved forward by the chain transport structure to achieve rapid, high-volume production, and products of different groups are not mixed with each other. The self-rotating and high-bearing sockets and the high-speed airflow carrying hot air increase the heating rate and uniformity, greatly improving the yield, output and production efficiency, and are highly effective.
