Description

自動適應包裝箱外型的列印系統Printing system that automatically adapts to the shape of the box

本發明係有關於列印系統，尤指一種針對不同尺寸或不同造型的包裝箱的表面進行列印的列印系統。The present invention relates to a printing system, especially a printing system for printing the surfaces of packing boxes of different sizes or shapes.

按，人們越來越常使用網路商場來購買各種產品，而大型的網路商場通常將各種產品存放在大型物流倉庫，再利用各種自動化設備來運送及包裝產品，讓產品可以盡快的交到消費者手上。對於物流倉儲業者而言，每天數以萬計的產品需要進行運送及包裝，如何將產品可以加快包裝及運送，乃是目前最常被提出來的問題，例如，物流倉儲業者的倉庫中，可能存放各家廠商或網路商場的產品，因此將大小不一的產品放入適當大小的各式包裝箱後，需要在包裝箱的表面印製不同的廠商或網路商場的名稱、商標或產品名稱等圖文，但是包裝箱大小不一，要印製的圖文也不相同，印製的位置也不一樣，如何才可以讓印製包裝箱表面圖文的速度快、品質好呢？Press, people use online shopping malls more and more often to buy various products, and large-scale online shopping malls usually store various products in large logistics warehouses, and then use various automated equipment to transport and package products, so that products can be delivered as soon as possible in the hands of consumers. For the logistics and warehousing industry, tens of thousands of products need to be shipped and packaged every day. How to speed up the packaging and transportation of products is the most frequently asked question. For example, in the warehouse of the logistics and warehousing industry, there may be Store products from various manufacturers or online shopping malls. Therefore, after placing products of different sizes into various packaging boxes of appropriate size, it is necessary to print the names, trademarks or products of different manufacturers or online shopping malls on the surface of the packaging box. Name and other graphics, but the size of the packaging box is different, the graphics and text to be printed are also different, and the printing position is also different. How can we make the printing speed and quality of the graphics and text on the surface of the packaging box fast and good?

基於上述的問題，已有業者提出不同的解決方案，舉例而言，里明多尼克公司(V.L. Limitronic, S.L.，網址：www.limitronic.com)的V5、V6及V7系列的產品，可以將客製化的圖文印製在包裝箱的表面。但是前述的產品只能在單一規格的包裝箱表面進行各種圖文的列印工作，而且只能列印在固定的位置，這樣並不適合應用在不同規格大小的包裝箱。Based on the above problems, the industry has proposed different solutions. For example, the V5, V6 and V7 series products of VL Limitronic, SL (website: www.limitronic.com) can be used by customers. The customized graphics are printed on the surface of the box. However, the aforementioned products can only print various images and texts on the surface of a single-size box, and can only be printed in a fixed position, which is not suitable for packaging boxes of different sizes.

而中國專利第CN104553359B號發明專利提出了「用於在多種不同類型的產品上進行打印的傳送打印系統及方法」(以下稱中國專利前案)，中國專利前案的摘要提到「系統包括模組化托盤，具有可互換的托盤嵌入物，構造為保持不同類型的產品。印表機系統還包括高度調整機構，調整托盤中產品的目標列印表面和打印頭噴嘴之間的距離。」。意即，中國專利前案是對不同規格大小的產品(並非包裝箱)印製圖文，而且在印製圖文時，需要依照產品的規格利用高度調整機構調整托盤高度，此外，托盤需要托盤嵌入物固定產品，才能讓托盤上不同規格的產品面對噴印頭的列印位置(請參閱中國專利前案說明書第0059段落)。但是升降托盤的高度，勢必會影響列印的速度，需要不同的托盤嵌入物固定產品，不僅引響包裝速度，也會增加額外的成本。And Chinese Patent No. CN104553359B proposed "Transfer printing system and method for printing on a variety of different types of products" (hereinafter referred to as the Chinese patent case), the abstract of the Chinese patent case mentioned that "the system includes a mold The modular tray, with interchangeable tray inserts, is constructed to hold different types of products. The printer system also includes a height adjustment mechanism that adjusts the distance between the target printing surface of the product in the tray and the print head nozzles.” That is to say, the previous Chinese patent case is to print pictures and texts on products of different sizes (not packaging boxes), and when printing pictures and texts, it is necessary to use a height adjustment mechanism to adjust the height of the tray according to the specifications of the product. In addition, the tray needs a tray. The product is fixed by the insert, so that the products of different specifications on the tray can face the printing position of the print head (please refer to paragraph 0059 of the description of the Chinese patent case). However, the height of the lifting tray will inevitably affect the printing speed. Different tray inserts are required to fix the product, which not only affects the packaging speed, but also increases the extra cost.

換言之，里明多尼克公司的產品及中國專利前案，都不能同時解決包裝箱大小不一，要印製的圖文也不相同，印製的位置也不一樣的問題，也就是說不同包裝箱的表面印製圖文的工作的問題，乃是目前亟待解決的問題。In other words, neither the products of Liminic Company nor the previous Chinese patent case can solve the problems of different sizes of packaging boxes, different graphics and texts to be printed, and different printing positions, that is to say, different packaging The problem of printing graphics and text on the surface of the box is an urgent problem to be solved at present.

有鑑於先前技術的問題，本發明之一目的係為了解決印製包裝箱表面圖文的問題，尤其是可以針對不同大小規格之包裝箱進行印製，而且可以將圖文印製在包裝箱的一定區域的範圍內，減少影響物流包裝的速度。In view of the problems of the prior art, one of the purposes of the present invention is to solve the problem of printing graphics and texts on the surface of the packaging boxes, especially for packaging boxes of different sizes and specifications, and the graphics and texts can be printed on the surface of the packaging boxes.

請參閱圖1及圖2所示，本發明係一種自動適應包裝箱外型地列印系統，包括輸送單元1及列印單元2，其中輸送單元1係接收及運送不同規格大小之包裝箱。輸送單元1包括第一輸送部10、第二輸送部12、第三輸送部14及第四輸送部16，其中第二輸送部12設在第一輸送部10的一端(亦可稱為第一輸送部10的入口)，第二輸送部12將包裝箱3送入到第一輸送部10，第三輸送部14設在第一輸送部10的另端(亦可稱為第一輸送部10的出口)，且第三輸送部14將包裝箱3送出。第四輸送部16設在第二輸送部12的入口，第四輸送部16之一側設有檢測器160，此檢測器160係檢測包裝箱3要印製圖文的一面(以下稱列印面30)是否朝向正確方向，當檢測器160感應到包裝箱3要印製圖文的一面並未朝向正確方向時，則經由自動適應包裝箱外型的列印系統的控制單元(例如：電腦，圖中未示)發送轉向訊號給第二輸送部14，令第二輸送部14將包裝箱3的列印面30朝向正確方向，在本發明中，圖文包括條碼(Bar Code)、快速響應矩陣圖碼(Quick Response Code，簡稱：QR Code)、標誌(logo)、商標、文字、數字、符號、照片或任何客製化資訊等，而且列印單元2可以接受外部來的操作而即時更新圖文。Please refer to FIG. 1 and FIG. 2 , the present invention is a printing system that automatically adapts to the shape of the packaging box, including a conveying unit 1 and a printing unit 2 , wherein the conveying unit 1 receives and transports packaging boxes of different sizes. The conveying unit 1 includes a first conveying part 10 , a second conveying part 12 , a third conveying part 14 and a fourth conveying part 16 , wherein the second conveying part 12 is provided at one end of the first conveying part 10 (also referred to as the first conveying part 10 ). The entrance of the conveying part 10), the second conveying part 12 sends the packaging box 3 to the first conveying part 10, and the third conveying part 14 is provided at the other end of the first conveying part 10 (also called the first conveying part 10). outlet), and the third conveying part 14 sends the packing box 3 out. The fourth conveying part 16 is arranged at the entrance of the second conveying part 12 , and a detector 160 is arranged on one side of the fourth conveying part 16 . 30) Whether it is facing the correct direction, when the detector 160 senses that the side of the packaging box 3 to be printed with graphics and text is not facing the correct direction, the control unit of the printing system (for example: computer, (not shown in the figure) send a steering signal to the second conveying part 14, so that the second conveying part 14 directs the printing surface 30 of the packaging box 3 to the correct direction. In the present invention, the pictures and texts include bar codes, quick response matrix Image code (Quick Response Code, referred to as: QR Code), logo (logo), trademark, text, numbers, symbols, photos or any customized information, etc., and the printing unit 2 can accept external operations to update the image in real time Arts.

本發明在實際實施時，輸送單元1只要在第二輸送部12可以調整包裝箱3方向的位置之前放置檢測器160，讓檢測器160可以檢測到列印面30是否朝向正確方向的一段區間者，即可稱為第四輸送部16。再者，本發明在包裝箱3的列印面30的預定位置(例如：列印面30的相鄰輸送單元的位置，或者列印面30的角落等位置)設有辨識標記(例如：一維條碼或二維碼)，而檢測器160係為標記辨識器(例如：條碼讀取器或二維條碼讀取器)，如此，當檢測器160沒有讀取到辨識標記，則檢測器160會發出檢測訊號到控制單元，讓控制單元可以發出轉向訊號到第二輸送部12，令第二輸送部12將包裝箱3轉向。In the actual implementation of the present invention, as long as the conveying unit 1 places the detector 160 before the second conveying part 12 can adjust the position of the packing box 3, so that the detector 160 can detect whether the printing surface 30 is facing the correct direction, That is, it can be called the fourth conveying part 16 . Furthermore, in the present invention, identification marks (for example, one-dimensional barcodes or two-dimensional code), and the detector 160 is a mark recognizer (for example, a barcode reader or a two-dimensional barcode reader), so, when the detector 160 does not read the identification mark, the detector 160 will send a detection The signal is sent to the control unit, so that the control unit can send a turning signal to the second conveying part 12 to make the second conveying part 12 turn the packing box 3 .

在此需要特別說明的是，一般包裝箱大多為矩形的紙箱，無論要在紙箱較長的一面或較短的一面印製圖文，都只要一個辨識標記在其中較長或較短的一面即可，原因是只要將紙箱轉動一次就會將紙箱從較長的一面轉向較短的一面。但若一定要將圖文印製在包裝箱特定的一面，則在第二輸送部12完成第一次轉動包裝箱3後的位置需要有另一檢測器，讓另一檢測器可以利用是否讀取到辨識標記來判斷包裝箱是否轉到列印面30，若另一檢測器尚未檢測到印製標記，則讓第二輸送部再次轉動包裝箱3，包裝箱3的列印面30即可朝向正確方向。It should be noted here that most of the general packing boxes are rectangular cartons. No matter if you want to print pictures on the longer side or the shorter side of the carton, you only need an identification mark on the longer or shorter side. Yes, because only one turn of the carton will turn the carton from the longer side to the shorter side. However, if the graphics and text must be printed on a specific side of the packaging box, another detector is required at the position after the second conveying part 12 completes the first rotation of the packaging box 3, so that the other detector can use whether to read or not. Get the identification mark to judge whether the packing box is turned to the printing surface 30. If another detector has not detected the printing mark, let the second conveying part rotate the packing box 3 again, and the printing surface 30 of the packing box 3 can be oriented correctly. direction.

在本發明中，第一輸送部10係為皮帶輸送帶，第二輸送部12係為萬向輸送帶，第三輸送部14係為皮帶輸送帶。第四輸送部16係可為皮帶輸送帶或者可為萬向輸送帶的一部份。再者，根據包裝箱的尺寸、數量以及列印單元2的列印速度等進行計算，而調整第一輸送部10、第二輸送部12第三輸送部14及第四輸送部16之間的運送速度及列印單元2的列印速度，藉以達到較高的列印效率。In the present invention, the first conveying portion 10 is a belt conveying belt, the second conveying portion 12 is a universal conveying belt, and the third conveying portion 14 is a belt conveying belt. The fourth conveyor portion 16 may be a belt conveyor belt or may be part of a universal conveyor belt. Furthermore, according to the size and quantity of the packaging boxes and the printing speed of the printing unit 2, etc., the distance between the first conveying part 10, the second conveying part 12, the third conveying part 14 and the fourth conveying part 16 is adjusted. The conveying speed and the printing speed of the printing unit 2 can achieve higher printing efficiency.

在該實施例中，請參閱圖1所示，第二輸送部12在檢測器160之後的預設距離設有一活動檔桿120及一驅動器122，驅動器122連接活動檔桿120，並且可以被驅動器122帶動朝向該第二輸送部12突伸，而當第二輸送部12可以是輸送帶或萬向輸送帶，包裝箱3往第二輸送部12的一側邊靠齊，當檢測器160沒有讀取到辨識標記，則檢測器160會發出檢測訊號到控制單元，讓控制單元可以發出轉向訊號到驅動器122，令活動檔桿120突伸到第二輸送部12上，讓包裝箱3被第二輸送部12帶動的過程，包裝箱3經過活動檔桿120時會逐漸轉向。但本發明實際實施時，並不限於此，例如：當第二輸送部12係為萬向輸送帶，可以由第二輸送部12直接將包裝箱轉向，意即，只要是在第二輸送部能夠將包裝箱轉向之手段皆是本發明所欲主張者。In this embodiment, please refer to FIG. 1 , the second conveying portion 12 is provided with a movable lever 120 and a driver 122 at a preset distance behind the detector 160 , and the driver 122 is connected to the movable lever 120 and can be driven by the driver 122 . 122 is driven to protrude toward the second conveying part 12, and when the second conveying part 12 can be a conveyor belt or a universal conveyor belt, the packing box 3 is aligned with one side of the second conveying part 12, when the detector 160 does not After reading the identification mark, the detector 160 will send a detection signal to the control unit, so that the control unit can send a turn signal to the driver 122, so that the movable lever 120 can protrude onto the second conveying part 12, so that the packing box 3 can be transported by the first During the driving process of the second conveying part 12 , the packing box 3 will gradually turn around when passing through the movable lever 120 . However, the actual implementation of the present invention is not limited to this. For example, when the second conveying part 12 is a universal conveyor belt, the packaging box can be directly turned by the second conveying part 12, that is, as long as the second conveying part 12 is in the second conveying part Means capable of turning the box are all claimed by the present invention.
