[0005] According to the method of the cited document 1, boxes of various sizes can be efficiently manufactured. However, the cited document 1 requires that the frame be separated from the box template after the box template is wrapped around the frame. In addition, the cited document 1 does not disclose a specific means for controlling the position of the adjustable part according to the size of various cardboard boxes (boxes). If the position is to be automatically controlled, the configuration will be complicated and a considerable amount of time will be required for the position control.

[0010] Hereinafter, a sheet processing device 1 according to an embodiment will be described with reference to the accompanying drawings. The processing device 1 can continuously perform a plurality of processes such as folding cardboard sheets 100 of different dimensions that are transported one after another. The cardboard sheet 100, which is an example of an object to be processed, has a rectangular shape in a plan view, and is transported to the processing device 1 after preliminary processing such as identifying the folding position has been performed.

[0011] [Overview of Processing Device 1: See Figure 1] The outline of a processing device 1 for processing a corrugated cardboard sheet 100 will be described. The processing device 1 includes a first processing area 201 which receives the cardboard sheet 100 upstream U and performs a first processing, and a second processing area 202 which receives the cardboard sheet 100 which has been subjected to a predetermined processing in the first processing area 201 downstream D of the first processing area 201 and performs a second processing.

[0012] In the cardboard sheet 100, a longitudinal direction L and a width direction W are specified. In the processing device 1, the upstream U and downstream D are specified by the direction in which the cardboard sheet 100 is transported. In Fig. 1, the direction in which the cardboard sheet 100 is transported is indicated by a hollow arrow, but the upstream U and downstream D have relative meanings. For example, the most downstream in the first processing area 201 is upstream of the second processing area 202. 1, a first direction X and a second direction Y are specified in the processing device 1. The cardboard sheet 100 is transported in the first direction X from the upstream U side to the first processing area 201, and is transported in the second direction Y from the first processing area 201 to the second processing area 202. In other words, in the processing device 1, the cardboard sheet 100 is transported with its orientation changed by 90°.

[0013] A first positioning reference 203 is defined in the first processing area 201, and a second positioning reference 204 is defined in the second processing area 202. The first positioning reference 203 is a reference for positioning the cardboard sheet 100 in the first direction X, and the second positioning reference 204 is a reference for positioning the cardboard sheet 100 in the second direction Y. A first processing reference position 103 corresponding to the first positioning reference 203 is specified in the cardboard sheet 100. The first processing reference position 103 is formed of a line segment parallel to the width direction W of the cardboard sheet 100. In addition, in the cardboard sheet 100, it is the center line C of the width direction W that is positioned by the second positioning reference 204. This center line C is an example of the second processing reference position of the present disclosure. Note that the second processing reference position of the present disclosure is not limited to the center line C, and for example, either one of the two edge lines in the width direction W of the cardboard sheet 100 can be set as the second processing reference position.

[0014] In the first processing area 201, the conveyance of the cardboard sheet 100 is stopped so that the first processing reference position 103 of the cardboard sheet 100 coincides with the first positioning reference 203. With the first processing reference position 103 coinciding with the first positioning reference 203, the cardboard sheet 100 is subjected to the first processing. As the first processing, the end portion in the longitudinal direction L beyond the first processing reference position 103 is folded at the first processing reference position 103. Note that the cardboard sheet 100 shown in the first processing area 201 in FIG. 1 is depicted in a state before the first processing reference position 103 reaches the first positioning reference 203, but the cardboard sheet 100 shown in the second processing area 202 has the first processing reference position 103 coinciding with the first positioning reference 203.

[0015] In the first processing area 201, the cardboard sheet 100 that has been subjected to the first processing is transported to the second processing area 202 with the first processing reference position 103 coinciding with the first positioning reference 203. When the center line C of the cardboard sheet 100 transported to the second processing area 202 in the width direction W coincides with the second positioning reference 204, the transport is stopped. At this time, the first processing reference position 103 remains coinciding with the first positioning reference 203. With the center line (second processing reference position) C coinciding with the second positioning reference 204, the cardboard sheet 100 is subjected to the second processing. In the second processing area 202, the cardboard sheet 100 is positioned in both the first direction X and the second direction Y, so the second processing is performed on the cardboard sheet 100 whose positions in the first direction X and the second direction Y have been specified.

[0016] 1, the first processing area 201 and the second processing area 202 are depicted with cardboard sheets 100 of the same dimensions, but the processing device 1 can process cardboard sheets 100 of different dimensions in each of the first processing area 201 and the second processing area 202. The dimensions of the cardboard sheet 100 transported to and processed in the first processing area 201 are known. Therefore, when the first processing is performed in the first processing area 201, and when the second processing is performed in the second processing area 202, the cardboard sheet 100 is positioned, i.e., the position is identified, and a necessary operation is performed based on the known dimensions.

[0017] [Outline of processing of cardboard sheets: see Figures 2 and 3] Next, an overview of processing a cardboard sheet as the cardboard sheet 100 will be described. Note that, here, an example of processing a small cardboard sheet 110 (110A, 110B, 110C) having the smallest dimensions and a large cardboard sheet 120 (120A, 120B, 120C) having the largest dimensions using the same processing device 1 will be described with reference to Figs. 2 and 3.

[0018] <Processing of small cardboard sheets 110A to 110C; Fig. 2> 2, it is assumed that the small cardboard sheet 110A, the small cardboard sheet 110B, and the small cardboard sheet 110C are transported in this order. In other words, among the small cardboard sheet 110A, the small cardboard sheet 110B, and the small cardboard sheet 110C, the small cardboard sheet 110A is transported to the processing device 1 first, and then the small cardboard sheet 110B is transported to the processing device 1 next. The small cardboard sheet 110A is processed in the second processing area 202, and the small cardboard sheet 110B is processed in the first processing area 201. The small cardboard sheet 110C is located upstream U of the first processing area 201. When the second processing of the small cardboard sheet 110A is completed in the second processing area 202, the small cardboard sheet 110A is transported toward the downstream D from the first processing area 201. Then, the small cardboard sheet 110B that has completed the first processing in the first processing area 201 is transported to the second processing area 202 and is subjected to the second processing. The waiting small cardboard sheet 110C is transported to the first processing area 201 and the first processing is performed on the small cardboard sheet 110C. In the processing device 1, the small cardboard sheets 110A to 110C ... that are continuously transported as described above are subjected to a predetermined processing in the first processing area 201 and the second processing area 202. The operation of this processing is the same even if the dimensions of the cardboard sheets are different.

[0019] A first folding position 113, a second folding position 115, and a bonding position 117 are specified for each of the small cardboard sheets 110A to 110C. The first folding position 113, the second folding position 115, and the bonding position 117 are parallel to the width direction W, and are specified at intervals in the longitudinal direction L. The first folding position 113 and the second folding position 115 correspond to the first processing reference position 103 and the second processing reference position C, respectively.

[0020] Each of the small cardboard sheets 110A to 110C has a first folding piece 114, a second folding piece 116, and a base piece 118. An adhesive piece 119 is provided at an end edge in the longitudinal direction L of the first folding position 113. The first folding piece 114 and the base piece 118 are separated by the first folding position 113, and the second folding piece 116 and the base piece 118 are separated by the second folding position 115. The adhesive position 117 is provided approximately in the center of the base piece 118 in the longitudinal direction L.

[0021] In the first processing area 201, the small cardboard sheet 110B is stopped from being conveyed when the first folding position 113 coincides with the first positioning reference 203. Then, the first folding piece 114 is folded using the first folding position 113 as a reference so that the first folding piece 114 overlaps the base piece 118. When the first folding piece 114 is folded, the adhesive piece 119 overlaps the adhesive position 117. This process of folding the first folding piece 114 corresponds to the first process, and the small cardboard sheet 110B that has completed the first process is conveyed toward the second processing area 202.

[0022] The small cardboard sheet 110A conveyed to the second processing area 202 has already been folded so that the first folding piece 114 overlaps the base piece 118, and the adhesive piece 119 coincides with the adhesive position 117. The second processing is performed in a state where the center line C of the small cardboard sheet 110A and the second positioning reference 204 are located. That is, after applying an adhesive such as hot melt to the adhesive piece 119, the second folding piece 116 is folded based on the second folding position 115 so that the second folding piece 116 overlaps the base piece 118. Then, the tip portion of the second folding piece 116 is adhered to the first folding piece 114 by the adhesive applied to the adhesive piece 119. This completes the second processing for the small cardboard sheet 110A. The small cardboard sheet 110A with the first folding piece 114 and the second folding piece 116 folded thereon is transported toward the next processing area provided downstream D.

[0023] <Processing of large cardboard sheets 120A to 120C; Fig. 3> The first and second processes of the large corrugated cardboard sheets 120A, 120B, and 120C are performed in the same manner as the first and second processes of the small corrugated cardboard sheets 110A, 110B, and 110C described with reference to Fig. 2. Therefore, the same elements as those in Fig. 2 are given the same reference numerals in Fig. 3, and repeated explanations are omitted here. Although the small corrugated cardboard sheets 110 and the large corrugated cardboard sheets 120, which have different dimensions, are processed by the same processing device 1, it should be noted that the positioning of the first folding position 113 relative to the first positioning datum 203 and the positioning of the center line C relative to the second positioning datum 204 are the same.

[0024] [Summary of processing procedures in processing device 1] <First Processing Region 201> By performing the following STEP 1 and STEP 2, the first folding piece 114 can be folded at the same position even if the cardboard sheets 100 have different dimensions. STEP 1: The first processing reference position 103 (first folding position 113) of the carried-in cardboard sheet 100 is positioned to the first positioning reference 203. STEP 2: A first process is performed to fold the first folding piece 114 at the first process reference position 103 (first folding position 113).

[0025] <Second Processing Region 202> By performing the following STEP 3 and STEP 4, even if the cardboard sheets 100 have different dimensions, the position of the center line C is the same, so that the cardboard sheets 100 can be easily conveyed to the downstream process D. STEP 3: In the second processing area 202, the center line C of the width direction W of the cardboard sheet 100 is positioned to the second positioning reference 204. STEP 4: A second process is performed in which the second folding piece 116 is folded at the second folding position 115 and the adhesive piece 119 is adhered to the second folding piece 116 .

[0026] [Processing device 2: see Figs. 4 to 8] A specific example of processing a corrugated cardboard sheet 100 using the processing device 2 will be described. First, the configuration of the processing device 2 will be described with reference to FIG. The processing device 2 includes a conveying section 20 that conveys the cardboard sheet 100, a first processing section 40 that performs a first processing on the cardboard sheet 100 carried in by the conveying section 20, and a second processing section 60 that performs a second processing on the cardboard sheet 100 that has been subjected to the first processing by the first processing section 40. The processing device 2 includes a control section (not shown) that controls the operations of the conveying section 20, the first processing section 40, and the second processing section 60. The conveying section 20, the first processing section 40, and the second processing section 60 will be described below in that order.

[0027] [Transport section 20: see Figure 4] The conveying section 20 includes an input machine 21 that receives the cardboard sheet 100 from the upstream U and conveys it to the first processing section 40, a conveying machine 23 that conveys the cardboard sheet 100 that has finished processing in the first processing section 40 to the second processing section 60, and an output machine (not shown) that conveys the cardboard sheet 100 that has finished processing in the second processing section 60 toward the downstream D.

[0028] The carry-in machine 21 includes a clamp 21A that grips the adhesive piece 119 of the cardboard sheet 100, and a movable body 21B that holds the clamp 21A and moves in a first direction X. The movable body 21B is capable of reciprocating movement on a conveying path along the first direction X (not shown) by, for example, a servo motor. When the carry-in machine 21 carries the cardboard sheet 100 into the first processing section 40, the moving body 21B travels toward the first processing section 40 with the clamp 21A gripping the adhesive piece 119. When the cardboard sheet 100 is carried in up to the first positioning reference of the first processing section 40, the carry-in machine 21 releases the clamp 21A from gripping the adhesive piece 119, then retreats from the first processing section 40, and holds the adhesive piece 119 of the cardboard sheet 100 to be processed next, waiting to be carried in.

[0029] The conveyor 23 includes a first conveyor 23A and a second conveyor 23B that are provided between the first processing section 40 and the second processing section 60. Each of the first conveyor 23A and the second conveyor 23B is, for example, a conveyor device. This conveyor device uses a servo motor as a driving source and includes a pair of timing pulleys 23C to at least one of which the rotational driving force of the servo motor is transmitted, and a timing belt 23D that is wound around the timing pulley 23C. The cardboard sheet 100 to be processed in the first processing section 40 is placed on the timing belts 23D, 23D of the first conveyor 23A and the second conveyor 23B while the first processing is being performed and while being transported to the second processing section 60.

[0030] The conveyor, not shown, fixes the cardboard sheet 100 in a fixed position in the second processing area 202 by means of, for example, vacuum suction, gripping, or other means, and conveys it further downstream to a process D. Since the cardboard sheet 100 is in a fixed position, the conveyor can perform the conveying operation by targeting, for example, the center line C of the cardboard sheet 100.

[0031] [First processing unit 40: Figs. 4, 5, and 6] The first processing section 40 includes a first folding machine 41 that folds a first folding piece 114 of the cardboard sheet 100 at a first folding position 113, and a first sheet pressing machine 43 that presses the base piece 118 along the first folding position 113 when the first folding machine 41 folds the first folding piece 114.

[0032] The first folding machine 41 includes a first folding plate 41A having a first reversing shaft 41C in contact with the first folding piece 114, and a first driving source 41D that reverses the first folding plate 41A around the first reversing shaft 41C. The first folding machine 41 includes a transmission mechanism 41E that transmits the rotational driving force of the first driving source 41D to the first folding plate 41A.

[0033] In the first processing area 201, until the first processing of the transported cardboard sheet 100 begins, the first folding machine 41 waits with the first pressing surface 41B of the first folding plate 41A facing upward, as shown in Figure 4.

[0034] When the cardboard sheet 100 is transported to a predetermined position, that is, until the aforementioned first folding position 113 coincides with the first positioning reference 203, the first sheet pressing machine 43, which had been waiting above as shown in FIG. 4, moves so as to press the base piece 118 along the first folding position 113 as shown in FIG. 5. When the base piece 118 is pressed by the first sheet pressing device 43, the first driving source 41D starts to apply a rotational driving force. This rotational driving force is transmitted to the first folding plate 41A via the transmission mechanism 41E, and the transmission mechanism 41E rotates around the first reversing shaft 41C. When the first folding plate 41A rotates by 180°, the first folding piece 114 is folded as shown in FIG. 6.

[0035] Upon completing the first process up to folding the first folding piece 114, the first folding machine 41 returns to a standby state and waits for the next cardboard sheet 100 to be processed. In addition, the cardboard sheet 100 with the first folding piece 114 folded is transported to the second processing area 202 by the transport machine 23. Specifically, the cardboard sheet 100 is transported until the center line C of the width direction W of the cardboard sheet 100 coincides with the second positioning reference 204.

[0036] [Second processing unit 60: Figs. 4, 7, and 8] The second processing section 60 includes a second folding machine 61 that folds the second folding piece 116 of the cardboard sheet 100 at the second folding position 115, and a second sheet pressing machine 63 that presses the base piece 118 along the second folding position 115 when the second folding machine 61 folds the second folding piece 116. The second folding machine 61 has a similar configuration and operates in the same manner as the first folding machine 41 of the first processing section 40, so the second folding machine 61 is given the same reference numerals as the respective elements of the first folding machine 41, and the description thereof will be omitted. The same applies to the second sheet pressing machine 63.

[0037] The second processing section 60 includes an adhesive applicator 65 that applies adhesive to the adhesive piece 119 of the cardboard sheet 100. The adhesive applicator 65 is disposed between the first processing area 201 and the second processing area 202, and applies adhesive to the adhesive piece 119 while the cardboard sheet 100 with the first folded piece 114 folded is being transported from the first processing area 201 to the second processing area 202.

[0038] The processing device 2 processes cardboard sheets 100 of different dimensions. Therefore, some of the components of the processing device 2 are configured to be changeable in position according to the dimensions of the cardboard sheets 100 so that the processing device 2 can perform the first and second processes described above for cardboard sheets 100 of different dimensions.

[0039] In the second processing section 60, the second folding position 115 in the first direction X varies depending on the dimensions of the cardboard sheet 100, particularly the dimension in the longitudinal direction L. Therefore, the positions of the second folder 61 and the second sheet presser 63 in the first direction X can be changed according to the dimensions of the cardboard sheet 100 to be processed. This changeable range is shown as an area AA surrounded by a dashed line in FIG. 8. Since the position of the adhesive piece 119 of the cardboard sheet 100 also changes depending on the dimensions, the position of the adhesive applicator 65 in the first direction X can also be changed. In order to accommodate the change in the dimension of the cardboard sheet 100 in the longitudinal direction L, the position of the first conveyor 23A in the first direction X can also be changed. In first processing section 40, the first processing can be performed with first folder 41 and the like remaining in their fixed positions.

[0040] [Processing procedure in processing device 2: see Figs. 4 to 8] <Waiting: Figure 4> A cardboard sheet 100 that has been adjusted to a predetermined specification, including dimensions, is carried into the first processing area 201 by the carry-in machine 21. At this time, the first processing section 40 is in the standby state described above. In the second processing section 60, components are on standby at positions according to the dimensions of the cardboard sheet 100 to be processed.

[0041] <First process: Fig. 5, Fig. 6> The first process begins when the cardboard sheet 100 is transported to a predetermined position in the first process area 201. First, the first sheet presser 43 is operated to press the base piece 118 of the cardboard sheet 100 along the first folding position 113 (FIG. 5). This completes preparation for folding, and then the first folding machine 41 is operated to invert and fold the first folding piece 114 (FIG. 6). The folded cardboard sheet 100 is transported toward the second process area 202. In the first process area 201, the first folding machine 41 is in a standby state until the next cardboard sheet 100 is brought in.

[0042] <Second process: Fig. 7, Fig. 8> When the cardboard sheet 100 is transported to a predetermined position in the second processing area 202, the second processing begins. The second sheet presser 63 is operated to press the base piece 118 of the cardboard sheet 100 along the second folding position 115, and the second folder 61 is operated to invert and fold the second folding piece 116. In addition, while the cardboard sheet 100 is being transported from the first processing area 201 to the second processing area 202, the adhesive applicator 65 applies adhesive AD to the adhesive piece 119.

[0043] While the second process is being performed in the second process area 202, the next cardboard sheet 100 to be processed is transported. When the next cardboard sheet 100 is transported to a predetermined position in the first process area 201, the first process is performed (FIG. 8). The cardboard sheet 100 with the first folding piece 114 and the second folding piece 116 folded is transported to the next process.

[0044] [Effects of the first embodiment (processing device 2)] <First effect> In the first processing area 201, the processing device 2 folds the first folding piece 114 as a first process in a state in which the first processing reference position 103 also serves as the first folding position 113, and these positions are aligned with the first positioning reference 203. Therefore, the processing device 2 can fold the first folding piece 114 efficiently and with high accuracy, because it positions cardboard sheets 100 of different dimensions using the same first positioning reference 203.

[0045] <Second effect> In the processing device 2, the cardboard sheet 100 transported to the second processing area 202 maintains its position in the first direction X, and the second folding position 115 can be easily recognized, so that the second folding piece 116 can be folded with high accuracy.

[0046] <Third Effect> In the processing device 2, the first processing area 201 and the second processing area 202 are aligned in the second direction Y, and the corrugated cardboard sheet 100 is transported from the first processing area 201 to the second processing area 202 in the width direction W of the corrugated cardboard sheet 100. Because the dimension of the width direction W is smaller than the longitudinal direction L, the transport distance from the first processing area 201 to the second processing area 202, i.e., the transport time, can be short. Therefore, according to the processing device 2, by shortening the transport time between the first processing and the second processing, the time required for one cycle of folding can be shortened, thereby improving the efficiency of making a box from the corrugated cardboard sheet 100.

[0047] <Fourth Effect> The processing device 2 applies the adhesive AD to the adhesive piece 119 in the process of transporting it from the first processing area 201 to the second processing area 202. Therefore, according to the processing device 2, since it is not necessary to set aside time for applying the adhesive AD, the time required for one cycle of folding can be shortened, thereby improving the efficiency of making a box from the cardboard sheet 100.

[0048] [Second embodiment (processing device 3): Figs. 9, 10, and 11] Next, a processing apparatus 3 according to a second embodiment will be described with reference to FIGS. In the processing device 2 according to the first embodiment, the cardboard sheet 100 transported in the first direction X to the first processing area 201 is transported in the second direction Y toward the second processing area 202 after the first processing is completed. Although this transport direction is a preferred embodiment in the present disclosure, the present disclosure also allows the cardboard sheet 100 transported in the first direction X to the first processing area 201 as in the processing device 3 to be transported in the first direction X toward the second processing area 202 after the first processing is completed. This is the second embodiment. That is, in the second embodiment, the first processing area 201 and the second processing area 202 are aligned in the first direction X.
