Description

TECHNICAL FIELD

[0001] The present application relates to a kind of product and processing method, in particular to a kind of convenient use of carbonless copy bill book and its production process. BACKGROUND

[0002] Carbonless copy paper is widely used in commercial bills such as bank, tax, telecommunications, postal, insurance, catering and other invoices, forms and other aspects due to its convenience, cleanliness, multiple copies, clear handwriting, easy processing, neat printing, and other advantages. Currently commonly used bill books such as receipt books and menu sheets are usually composed of two to three carbonless copy papers, which are used for handwriting in the work site and are particularly convenient to use. When using this bill book, the customer copy is often torn off and given to the customer, and a copy is left as a record of the transaction. The customer copy of the existing bill book is torn by hand, which often causes damage, an unattractive appearance, and makes it difficult to use the remaining paper. The new production process is designed for the improved bill book.

[0003] Carbonless copy paper, also known as pressure-sensitive printing paper, is composed of upper paper, middle paper and lower paper. The back of the upper paper and the middle paper is coated with a color former (CB coating), and the front of the middle paper and the lower paper is coated with a color former (CF coating). The front of the upper paper and the back of the lower paper are the original paper surface without coating. It is a chemical reaction principle of color development using microcapsule color former layer and acid clay in color former layer. When printing, the printing needle is pressed on the paper surface, crushing the microcapsule to react with the color former and achieve color development. The common color development layer is 2 to 6 layers (each layer is usually referred to as a copy, the first copy can also be referred to as the upper copy, the second layer is the second copy, and so on). It is mainly used for continuous printing of needle type printers and can also be handwritten to achieve the effect of copying multiple copies at the same time.

[0004] The carbonless copy paper separating glue (referred to as "separating glue" in this patent document) is a water-soluble adhesive specially used for processing carbonless copy paper. When processing printed carbonless copy paper, it is often necessary to make upper, middle and lower paper sets of carbonless copy paper prints. When the separating glue is applied to the edge of the already collated carbonless copy paper bundle, the carbonless copy paper sets can be separated after drying. The principle of the separating glue is that the separating glue is difficult to spread on the original paper surface but easy to spread on the CB and CF coatings. When the separating glue is applied to the edge of the already collated carbonless copy paper bundle, the separating glue is easy to penetrate into the "CB coating-CF coating" gap and difficult to penetrate into the "original paper surface-original paper surface" gap. Therefore, the "CB coating-CF coating" gap will absorb more glue and make the CB-CF coating firmly bonded, and vice versa. The "original paper surface-original paper surface" gap will absorb less glue and cannot form effective bonding. Therefore, the carbonless copy paper bundle treated with the separating glue can be separated into sets after being slightly tapped. Moreover, the adhesion of the separating glue will not cause mutual penetration and bonding between the paper, that is, the paper can be easily separated with a tearing force without damaging the paper, and the paper can remain flat after being torn.

[0026] BRIEF DESCRIPTION OF DRAWINGS: 1-core, 2-backing plate, 3-complete bill, 4-separating glue, 5-staple, 6-cover, 7-glue. DETAILED DESCRIPTION

[0027] In order to make the implementation purpose, technical scheme and advantages of the present application more clear, the present application scheme is described in detail in the form of embodiments in combination with the drawings.

[0028] The embodiment one, as shown in Fig. 1, the convenient carbonless copy bill book includes the bill core 1 and the backing plate 2; the bill core 1 is composed of the neatly stacked sets of bill 3, the right side of the bill core 1 is the glued edge 11, and the left end is the binding end 12; the separating glue 4 is brushed on the side of the glued edge 11, and the binding end 12 is bound to the backing plate 2 by the staple 5; the set of bill 3 is composed of the upper paper 31, the middle paper 32 and the lower paper 33 of carbonless copy paper, wherein the upper paper 31 and the middle paper 32 are shorter than the lower paper 33 at the binding end 12, and are not bound by the staple 5; the width of the backing plate 2 is the same as the width of the bill core 1, the backing plate 2 has two folds 21 in the middle, which divide the backing plate 2 into the plate bottom 22, the plate side 23 and the plate face 24, wherein the length of the plate bottom 22 is equal to the length of the lower paper 33, the length of the plate side 23 is equal to the thickness of the bill core 1, and the length of the plate face 24 is equal to the length of the upper paper 31. The shape of the finished product is shown in Fig. 2. Figure 2

[0029] The number of layers of the middle paper 32 can be 0-6, when the number of layers of the middle paper 32 is 0, the set of bill 3 is composed of the upper paper 31 and the lower paper 33, that is, a two-copy bill; when the number of layers of the middle paper 32 is 1, the set of bill 3 is composed of the upper paper 31, the middle paper 32 and the lower paper 33, that is, a three-copy bill; when the number of layers of the middle paper 32 is 2, the set of bill 3 is composed of the upper paper 31, two layers of the middle paper 32 and the lower paper 33, that is, a four-copy bill, and so on, which can form various multi-copy bills.

[0030] Because the bill core 1 has the separating glue 4 brushed on the side of the glued edge 11, according to the working principle of the separating glue 4, under the action of the separating glue 4, the upper paper 31, the middle paper 32 and the lower paper 33 of the set of bill 3 can be bonded together, and the set of bill 3 and the set of bill 3 are in contact with the back of the lower paper 33 and the front of the upper paper 31 (i.e. "original paper face - original paper face"), and will not be bonded by the separating glue 4. When used, the set of bill 3 is bonded by the separating glue 4, which achieves the effect of neat writing of each copy. The sets of bill 3 are bound together by the staple 5 at the binding end 12 to form the bill core 1 of the whole book. At the same time, the backing plate 2 is also bound below the bill core 1, the backing plate 2 is made of hardboard, and when used, the plate face of the backing plate 2 is inserted into the set of bill 3 to be written below to write, and the bill below the backing plate 2 will not develop color by bearing the writing pressure with the backing plate 2. Because the upper paper 31 and the middle paper 32 are shorter than the lower paper 33 at the binding end 12, and are not bound by the staple 5, the upper paper 31 and the middle paper 32 can be quickly torn off after writing, without damaging the paper, and the torn paper can keep the integrity and flatness of the paper, with good aesthetics. When the whole bill book is used up, because the binding end 12 is not affected by the residual paper head after tearing of the traditional bill book, the thickness is consistent, and it is more convenient to stack and store.

[0031] ​In the second embodiment, as shown in FIG3, this convenient carbonless copy bill book further includes a cover 6 based on the first embodiment. The cover 6 is bonded to the core 1 and the backing plate 2 at the binding end 12 with glue 7. After bonding, the upper portion forms a front cover 61 and the lower portion forms a back cover 62. The front cover 61 and the back cover 62 are flush with the four sides of the bill set 3. The finished product is shaped like this. Figure 4 shown.

[0032] After using the cover 6, information related to the product identification can be printed on the cover 6, which is convenient for users to write labels when using the product, thereby increasing the integrity of the product. For the product without the cover 6 in the first embodiment, information related to the product identification can be printed on the backing plate 2.

[0033] This convenient carbonless copy receipt book is often a form receipt with pre-printed images, text and serial numbers. The following is a production process designed for this product.

[0034] Example 3, as shown in the attached Figure 5 The figure shows a production process flow chart for realizing the product of Example 1. This production process includes the following steps:

[0035] Process 100, Multi-row Printing: Using roll-type carbonless copy paper as the raw material, a rotary printing press prints multiple rows of sheets of paper in separate sheets, which are then collected as a semi-finished roll. The separate sheets here refer to the upper sheet 31, the middle sheet 32, and the lower sheet 33 being printed separately. Multi-row printing involves printing multiple sheets side by side when the width of the set of bills 3 is small. This process greatly increases production efficiency for printing and post-printing. After processing, the sheets are cut to the final size to form multiple finished products.

[0036] Process 200, collating and cutting: the roll type semi-finished product is collated by a rotary collating machine according to the stacking order of the upper paper 31, the middle paper 32 and the lower paper 33, and at the same time, numbering, division of the book mark, cutting and vibration paper collecting are performed. The numbering method is to print serial numbers on each bill by a mechanical rotary numbering machine, the numbering machine includes a steel number machine, a number dialer, an ink device and a numbering bottom roller, the number dialer dials a number once for the number machine every rotation, and the number machine contacts the ink device to print ink once, and the number machine prints the number on the semi-finished product when it rotates to the semi-finished product, wherein the upper paper 31 is printed with the number by the ink, and the middle paper 32 and the lower paper 33 are colored by the pressure generated by the contact between the number machine and the numbering bottom roller to print the number; the division of the book mark is to divide a mark line on the semi-finished product by a counting device according to the number of the complete set of bills 3 contained in each book core 1, for example, if 30 bills are set in each book core 1, a division mark line is drawn every 30 bills, the line is on the edge of the paper, and manual identification can be performed on the side after stacking; the cutting is to cut the continuous collated semi-finished product into single semi-finished products by a rotary cutting device, and the cut single semi-finished products fall on the conveying belt and are conveyed backward; and the vibration paper collecting method is to stack the single semi-finished products in order by high-frequency vibration on a vibration paper collecting table, and the semi-finished products are taken out according to the set number, and the number of the semi-finished products in each stack is generally a multiple of the number of the book core 1, for example, 20 books are stacked, and if 30 bills are in each book, 600 bills are stacked, so that the number control in the subsequent process is facilitated.

[0037] Process 300, cutting and edge gluing: the edge gluing 11 of each stack of semi-finished products is cut by a paper cutter. In order to ensure that the separation glue 4 is uniformly distributed and penetrated in the subsequent brushing, the brushing surface must be neat, so that the whole stack is cut at one time to ensure that the cutting surface is flat and has no burrs.

[0038] Process 400, brushing separation glue: the separation glue 4 is brushed on the side of the edge gluing 11 of each stack of semi-finished products by a brush, and is naturally dried. When the air temperature is low and the drying speed is slow, a fan can be used for drying.

[0039] Process 500, division of books and pad plate: the semi-finished products with brushed separation glue 4 are divided according to the division mark line, and a pad plate is arranged under each book. After the pad plate is arranged, the pad plate should be aligned with the semi-finished product, and the semi-finished products are stacked neatly.

[0040] Process 600, binding: the semi-finished products of each book are bound together with the pad plate by a binding machine, two staples 5 are arranged on each book to bind the semi-finished products, and the semi-finished products are stacked neatly.

[0041] Process 700, cutting: the finished product is cut to the size of the finished product by a cutting machine. Here, cutting also includes the removal of the excess margin on both sides of the semi-finished product, ensuring that the finished product is neat and uniform in width, meeting the requirements of the finished product.

[0042] Process 800, film packaging: the finished product is stacked according to the set number, and is packaged with a heat-shrinkable film by a heat-shrinkable film packaging machine to form a package of finished products. Generally, 10 books are packaged, which is convenient for sales counting and pricing. When the finished product is stacked, the base plate 2 should be folded on the base plate 1 according to the style of the finished product (as shown in the accompanying drawings). Figure 2

[0043] Example four, as shown in the accompanying drawings, is a production process flow chart for realizing the product of example two. This production process is based on the production process of example one described above, and further includes the following processes after the binding process in process 600. Figure 6

[0044] Process 650, paste the cover: the printed cover 6 is pasted on the binding edge of the core 1 and the base plate 2 by glue 7. The pasting operation can be done manually or by special equipment, and the cover 61 should be aligned with the glue binding edge 11 after pasting.

[0045] The subsequent processes are the cutting process 700 and the film packaging process 800 described above. In the film packaging process, when the finished product is stacked, the base plate 2 should be folded on the cover 61 and the core 1 according to the style of the finished product (as shown in the accompanying drawings). Figure 4

[0046] The technical solution described in the present application uses ordinary materials and is suitable for industrial production, and has realizability and practicality.​​​
