[0024] Figure 11 It means succession Figure 10 A side view of the processing steps involved in the second embodiment. Detailed Implementation

[0025] Hereinafter, with reference to the accompanying drawings, the cardboard processing apparatus 1 according to the embodiment will be described. The processing apparatus 1 is capable of continuously performing multiple processes, such as folding corrugated cardboard 100 of different sizes that are continuously conveyed. As an example of the object to be processed, the corrugated cardboard 100 is rectangular in shape when viewed from above, and is conveyed to the processing apparatus 1 in a state where preparatory processes such as determining the folding position have been performed.

[0026] [Summary of Processing Device 1: Reference] Figure 1 ]

[0027] An overview of the processing apparatus 1 for processing corrugated cardboard 100 will be described.

[0028] The processing apparatus 1 includes: a first processing area 201, upstream U, for receiving corrugated cardboard 100 and performing a first processing; and a second processing area 202, downstream D of the first processing area 201, for receiving corrugated cardboard 100 that has undergone a predetermined processing in the first processing area 201 and performing a second processing.

[0029] In the corrugated cardboard 100, the length direction L and the width direction W are defined.

[0030] In processing device 1, the upstream U and downstream D are determined according to the direction in which the corrugated cardboard 100 is conveyed. Figure 1 In the diagram, white arrows indicate the direction in which the corrugated cardboard 100 is conveyed, but upstream U and downstream D have relative meanings. For example, the downstreammost part of the first processing area 201 is located further upstream than the second processing area 202.

[0031] Furthermore, in processing device 1, such as Figure 1 As shown, a first direction X and a second direction Y are defined. The corrugated cardboard 100 is conveyed along the first direction X from one side of the upstream U to the first processing area 201, and along the second direction Y from the first processing area 201 to the second processing area 202. That is, in the processing device 1, the corrugated cardboard 100 is conveyed after changing direction by only 90°.

[0032] 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 corrugated cardboard 100 in the first direction X, and the second positioning reference 204 is a reference for positioning the corrugated cardboard 100 in the second direction Y. A first processing reference position 103 corresponding to the first positioning reference 203 is defined on the corrugated cardboard 100. The first processing reference position 103 is composed of a line segment parallel to the width direction W of the corrugated cardboard 100. Furthermore, the center line C in the width direction W is positioned at the second positioning reference 204 in the corrugated cardboard 100. This center line C is an example of the second processing reference position of the present invention. In addition, the second processing reference position of the present invention is not limited to the center line C; for example, either of the two edge lines in the width direction W of the corrugated cardboard 100 can also be used as the second processing reference position.

[0033] In the first processing area 201, the conveying of the corrugated cardboard 100 is stopped such that the first processing reference position 103 of the corrugated cardboard 100 aligns with the first positioning reference 203. With the first processing reference position 103 aligned with the first positioning reference 203, the corrugated cardboard 100 undergoes the first processing. As part of the first processing, a portion of the cardboard 100 folded at the end further along the length direction L from the first processing reference position 103. Furthermore, Figure 1 The corrugated cardboard 100 shown in the first processing area 201 depicts the state before the first processing reference position 103 reaches the first positioning reference 203, but the corrugated cardboard 100 shown in the second processing area 202 depicts the state where the first processing reference position 103 is consistent with the first positioning reference 203.

[0034] In the first processing area 201, with the first processing reference position 103 aligned with the first positioning reference 203, the corrugated cardboard 100, having undergone the first processing, is transferred to the second processing area 202. If the centerline C in the width direction W aligns with the second positioning reference 204, the corrugated cardboard 100 transferred to the second processing area 202 stops being transferred. At this time, the first processing reference position 103 remains aligned with the first positioning reference 203. With the centerline (second processing reference position) C aligned with the second positioning reference 204, the corrugated cardboard 100 undergoes the second processing. In the second processing area 202, the corrugated cardboard 100 has been positioned in both the first direction X and the second direction Y; therefore, the second processing is performed on the corrugated cardboard 100 whose positions in the first direction X and the second direction Y are determined.

[0035] exist Figure 1In this embodiment, corrugated cardboard 100 of the same size is depicted in the first processing area 201 and the second processing area 202, but the processing apparatus 1 is capable of processing corrugated cardboard 100 of different sizes in the first processing area 201 and the second processing area 202 respectively. The dimensions of the corrugated cardboard 100 conveyed 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 the second processing is performed in the second processing area 202, the required actions are performed on the corrugated cardboard 100 that is positioned, i.e., has a defined position, based on its known dimensions.

[0036] [Overview of Corrugated Cardboard Processing: Reference] Figure 2 , Figure 3 ]

[0037] Next, as for corrugated cardboard 100, an overview of the processing of corrugated cardboard will be explained. Additionally, please refer to [reference needed]. Figure 2 and Figure 3 An example will be given of using the same processing apparatus 1 to process the smallest size small corrugated cardboard 110 (110A, 110B, 110C) and the largest size large corrugated cardboard 120 (120A, 120B, 120C).

[0038] Treatment of small corrugated cardboard 110A-110C; Figure 2 >

[0039] exist Figure 2 In this embodiment, it is assumed that corrugated cardboard 110A, corrugated cardboard 110B, and corrugated cardboard 110C are conveyed sequentially. That is, among corrugated cardboard 110A, corrugated cardboard 110B, and corrugated cardboard 110C, corrugated cardboard 110A is conveyed to processing device 1 first, followed by corrugated cardboard 110B. Corrugated cardboard 110A is processed in the second processing area 202, and corrugated cardboard 110B is processed in the first processing area 201. Corrugated cardboard 110C is located upstream of the first processing area 201.

[0040] If the second processing of the corrugated cardboard 110A is completed in the second processing area 202, the corrugated cardboard 110A is conveyed to a position D further downstream than the first processing area 201. Then, the corrugated cardboard 110B, whose first processing has ended in the first processing area 201, is conveyed to the second processing area 202 and subjected to the second processing. The corrugated cardboard 110C, which is in standby mode, is conveyed to the first processing area 201 and subjected to the first processing. In the processing apparatus 1, as described above, the continuously conveyed corrugated cardboard 110A~110C… are subjected to prescribed processing in the first processing area 201 and the second processing area 202.

[0041] The processing procedure remains the same regardless of the size of the corrugated cardboard.

[0042] In each of the corrugated cardboard pieces 110A to 110C, a first fold position 113, a second fold position 115, and a bonding position 117 are defined. The first fold position 113, the second fold position 115, and the bonding position 117 are parallel to the width direction W and are defined at intervals in the length direction L. The first fold position 113 and the second fold position 115 correspond to the first processing reference position 103 and the second processing reference position C, respectively.

[0043] Corrugated cardboard 110A to 110C each have a first fold sheet 114, a second fold sheet 116, and a base sheet 118. An adhesive sheet 119 is provided at the end edge along the length L of the first fold position 113. The first fold sheet 114 and the base sheet 118 are distinguished by the first fold position 113, and the second fold sheet 116 and the base sheet 118 are distinguished by the second fold position 115.

[0044] The bonding position 117 is located approximately at the center of the length direction L of the substrate 118.

[0045] In the first processing area 201, if the first fold position 113 coincides with the first positioning reference 203, the conveying of the small corrugated cardboard 110B stops. Then, the first fold piece 114 is folded with the first fold position 113 as a reference, so that the first fold piece 114 overlaps with the base sheet 118. If the first fold piece 114 is folded, the adhesive piece 119 overlaps with the adhesive position 117.

[0046] The process of folding the first fold 114 corresponds to the first process, and the corrugated cardboard 110B, which is the end of the first process, is conveyed toward the second process area 202.

[0047] The corrugated cardboard 110A, conveyed to the second processing area 202, is folded so that the first fold 114 overlaps with the base sheet 118, and the adhesive sheet 119 aligns with the adhesive position 117. With the centerline C of the corrugated cardboard 110A aligned with the second positioning reference 204, the second processing is performed. That is, after applying a hot melt adhesive or other adhesive to the adhesive sheet 119, the second fold 116 is folded with the second fold position 115 as a reference, so that the second fold 116 overlaps with the base sheet 118. The leading edge of the second fold 116 is then bonded to the first fold 114 using the adhesive applied to the adhesive sheet 119. This completes the second processing of the corrugated cardboard 110A. The corrugated cardboard 110A, with the first fold 114 and the second fold 116 folded, is conveyed towards the next processing area located downstream D.

[0048] Treatment of corrugated cardboard 120A-120C; Figure 3 >

[0049] Reference Figure 2 The first and second treatments of the small corrugated cardboard 110A, 110B, and 110C, which are described herein, are similarly performed on the large corrugated cardboard 120A, 120B, and 120C. Therefore, regarding the... Figure 2 The same requirements, in Figure 3 The same symbols are marked in the text, and repeated explanations are omitted here. Of course, small corrugated cardboard 110 and large corrugated cardboard 120 of different sizes are processed by the same processing device 1, but it should be noted in advance that the positioning of the first fold position 113 relative to the first positioning reference 203 and the positioning of the center line C relative to the second positioning reference 204 are common.

[0050] [Summary of processing steps in processing device 1]

[0051] <Processing Area 1 201>

[0052] By following steps 1 and 2, even corrugated cardboard 100 of different sizes can be folded in the same position to form the first fold piece 114.

[0053] Step 1: Position the first processing reference position 103 (first fold position 113) of the corrugated cardboard 100 that has been moved in to the first positioning reference 203.

[0054] Step 2: Perform the first process of folding the first fold piece 114 at the first processing reference position 103 (first fold position 113).

[0055] <Processing Area 202>

[0056] By following steps 3 and 4, even corrugated cardboard 100 of different sizes can be easily moved to the downstream process D because the center line C is in the same position.

[0057] Step 3: In the second processing area 202, position the center line C of the width direction W of the corrugated cardboard 100 to the second positioning reference 204.

[0058] Step 4: Perform the second process of folding the second fold piece 116 at the second fold position 115 and attaching the adhesive piece 119 to the second fold piece 116.

[0059] [Processing device 2: Reference] Figures 4-8 ]

[0060] An example of using a specific processing device 2 to process corrugated cardboard 100 will be described.

[0061] First, according to Figure 4The structure of the processing device 2 will be explained.

[0062] The processing apparatus 2 includes: a conveyor unit 20 for conveying corrugated cardboard 100; a first processing unit 40 for performing a first processing on the corrugated cardboard 100 brought in by the conveyor unit 20; and a second processing unit 60 for performing a second processing on the corrugated cardboard 100 that has undergone the first processing by the first processing unit 40. The processing apparatus 2 includes a control unit (shown incompletely) that controls the operation of the conveyor unit 20, the first processing unit 40, and the second processing unit 60. Hereinafter, the conveyor unit 20, the first processing unit 40, and the second processing unit 60 will be described in that order.

[0063] [Transportation Department 20: Reference] Figure 4 ]

[0064] The conveying unit 20 includes: a receiving machine 21 that receives corrugated cardboard 100 from upstream U and conveys it to the first processing unit 40; a conveyor 23 that conveys the corrugated cardboard 100 that has finished processing in the first processing unit 40 to the second processing unit 60; and a receiving machine (not shown) that removes the corrugated cardboard 100 that has finished processing in the second processing unit 60 towards the downstream D.

[0065] The loading machine 21 includes a clamp 21A that holds the adhesive sheet 119 of the corrugated cardboard 100 and a moving body 21B that holds the clamp 21A and moves along a first direction X. The moving body 21B can, for example, reciprocate along a conveying path along the first direction X (not shown) by a servo motor.

[0066] Regarding the loading machine 21, when the corrugated cardboard 100 is loaded into the first processing unit 40, the moving body 21B moves toward the first processing unit 40 while the clamp 21A holds the adhesive sheet 119. If the corrugated cardboard 100 is loaded to the first positioning reference of the first processing unit 40, it retracts from the first processing unit 40 after the clamp 21A releases the grip on the adhesive sheet 119, and holds the adhesive sheet 119 of the corrugated cardboard 100 to be processed next while waiting to be loaded.

[0067] Conveyor 23 includes a first conveyor 23A and a second conveyor 23B spanning between the first processing unit 40 and the second processing unit 60. As an example, the first conveyor 23A and the second conveyor 23B are each constructed by a conveying device. This conveying device includes: a pair of synchronous pulleys 23C, a servo motor serving as the drive source, and the rotational driving force of the servo motor being transmitted to one of them; and a synchronous belt 23D wound around the synchronous pulleys 23C. During the first processing and during the transfer to the second processing unit 60, the corrugated cardboard 100 processed in the first processing unit 40 is placed on the synchronous pulleys 23D of the first conveyor 23A and the second conveyor 23B.

[0068] The conveying machine (not shown) secures the corrugated cardboard 100, located at a predetermined position in the second processing area 202, using methods such as vacuum suction or gripping, and then moves it further downstream towards the process D. Since the corrugated cardboard 100 is in the predetermined position, the conveying machine can, for example, perform the conveying operation with the centerline C of the corrugated cardboard 100 as the target.

[0069] [Processing Section 1, Unit 40:] Figure 4 , Figure 5 , Figure 6 ]

[0070] The first processing unit 40 includes: a first folding machine 41, which folds the first folding piece 114 of the corrugated cardboard 100 at the first folding position 113; and a first cardboard pressing machine 43, which presses the substrate 118 along the first folding position 113 while the first folding piece 114 is folded by the first folding machine 41.

[0071] The first folding machine 41 includes: a first folding plate 41A having a first flipping shaft 41C that contacts the first folding piece 114; and a first drive source 41D that flips the first folding plate 41A around the first flipping shaft 41C. The first folding machine 41 includes a transmission mechanism 41E that transmits the rotational driving force of the first drive source 41D to the first folding plate 41A.

[0072] In the first processing area 201, such as Figure 4 As shown, the first folding machine 41 is in standby mode with the first pressing surface 41B of the first folding plate 41A facing upwards until the first processing of the corrugated cardboard 100 that has been moved in begins.

[0073] If the corrugated cardboard 100 is moved to the designated position, that is, the position where the first fold position 113 and the first positioning reference 203 are consistent, then as Figure 5 As shown, previously Figure 4 The first cardboard press 43, which is waiting above, moves along the first fold position 113 to press the substrate 118.

[0074] If the substrate 118 is pressed by the first cardboard press 43, the first drive source 41D begins to rotate. This rotational driving force is transmitted to the first folding plate 41A via the transmission mechanism 41E, which rotates around the first flipping axis 41C. If the first folding plate 41A rotates 180°, then... Figure 6 As shown, the first fold piece 114 is folded.

[0075] If the first processing step, up to the folding of the first folding piece 114, is completed, the first folding machine 41 returns to the standby state and awaits the arrival of the next corrugated cardboard 100 to be processed. The corrugated cardboard 100 after folding the first folding piece 114 is then conveyed to the second processing area 202 via conveyor 23. Specifically, the corrugated cardboard 100 is conveyed until the centerline C of the width direction W of the corrugated cardboard 100 aligns with the second positioning reference 204.

[0076] [Second Processing Section 60:] Figure 4 , Figure 7 , Figure 8 ]

[0077] The second processing unit 60 includes: a second folding machine 61, which folds the corrugated cardboard 100 at the second fold position 115 to form a second fold sheet 116; and a second cardboard pressing machine 63, which presses the base sheet 118 along the second fold position 115 while the second fold sheet 116 is folded by the second folding machine 61. The second folding machine 61 has the same structure as the first folding machine 41 of the first processing unit 40 and performs the same operation; therefore, the second folding machine 61 is marked with the same symbols as the first folding machine 41, and its description is omitted. The same applies to the second cardboard pressing machine 63.

[0078] The second processing unit 60 includes an adhesive coating machine 65 that applies adhesive to the bonding sheet 119 of the corrugated cardboard 100. The adhesive coating machine 65 is positioned between the first processing area 201 and the second processing area 202, and applies adhesive to the bonding sheet 119 during the process of the corrugated cardboard 100 after the first fold sheet 114 is folded and conveyed from the first processing area 201 to the second processing area 202.

[0079] The processing device 2 processes corrugated cardboard 100 of different sizes. Therefore, the processing device 2 is configured such that the position of the components corresponding to the size of the corrugated cardboard 100 can be changed so that the first and second processing described above can be performed on corrugated cardboard 100 of different sizes.

[0080] In the second processing unit 60, the second folding position 115 in the first direction X varies depending on the dimensions of the corrugated cardboard 100, particularly its length direction L. Therefore, the positions of the second folding machine 61 and the second cardboard pressing machine 63 in the first direction X are variable depending on the dimensions of the corrugated cardboard 100 to be processed. The range of variable positions is as follows: Figure 8 The area AA, enclosed by a dotted line, is shown. The position of the adhesive sheet 119 of the corrugated cardboard 100 changes depending on its size, therefore the position of the adhesive coater 65 in the first direction X is also variable. To accommodate changes in the length direction L of the corrugated cardboard 100, the position of the first conveyor 23A in the first direction X is also variable.

[0081] The first processing unit 40, the first folding machine 41, etc., can perform the first processing while still in the predetermined position.

[0082] [Processing steps in processing device 2: Refer to] Figures 4-8 ]

[0083] <Standby: Figure 4 >

[0084] The corrugated cardboard 100, including its dimensions, is adjusted to the specified specifications and then fed into the first processing area 201 via the feeder 21. At this time, the first processing unit 40 is in the aforementioned standby state. The components of the second processing unit 60 are in standby positions corresponding to the dimensions of the corrugated cardboard 100 to be processed.

[0085] <First Process: Figure 5 , Figure 6 >

[0086] If the corrugated cardboard 100 is conveyed to the designated position in the first processing area 201, the first processing begins. First, the first cardboard press 43 is activated to press the base sheet 118 of the corrugated cardboard 100 along the first fold position 113. Figure 5 Thus, the folding preparation is complete, and therefore, the first folding machine 41 is then activated, thereby causing the first folding piece 114 to flip and fold. Figure 6 The folded corrugated cardboard 100 is conveyed toward the second processing area 202.

[0087] In the first processing area 201, the first folding machine 41 is in standby mode until the next corrugated cardboard 100 is conveyed.

[0088] <Second Process: Figure 7 , Figure 8 >

[0089] If the corrugated cardboard 100 is conveyed to the designated position in the second processing area 202, the second processing begins.

[0090] The second cardboard press 63 is operated to press the base sheet 118 of the corrugated cardboard 100 along the second fold position 115, and the second fold sheet 116 is flipped and folded by operating the second folding machine 61. Figure 7 ).

[0091] In addition, during the process of corrugated cardboard 100 being transferred from the first processing area 201 to the second processing area 202, adhesive AD is applied to the adhesive sheet 119 by the adhesive coating machine 65.

[0092] During the second processing in the second processing area 202, the next corrugated cardboard 100 to be processed is conveyed in. If the next corrugated cardboard 100 is moved into the designated position in the first processing area 201, the first processing is performed. Figure 8 The corrugated cardboard 100, after being folded by the first fold piece 114 and the second fold piece 116, is moved toward the next process.

[0093] [Effects based on the first embodiment (processing device 2)]

[0094] <First Effect>

[0095] In the first processing area 201, the first processing reference position 103 also serves as the first folding position 113, and the processing device 2 performs the folding of the first folding piece 114 as the first process while aligning these positions with the first positioning reference 203. Therefore, even with corrugated cardboard 100 of different sizes, the processing device 2 can be positioned on the same first positioning reference 203, thus enabling efficient and high-precision folding of the first folding piece 114.

[0096] <Second Effect>

[0097] In the processing device 2, the corrugated cardboard 100 conveyed to the second processing area 202 is still in the position of maintaining the first direction X, and the second fold position 115 can be easily identified, so the second fold piece 116 can be folded with high precision.

[0098] <Third Effect>

[0099] In the processing apparatus 2, the first processing area 201 and the second processing area 202 are arranged along the second direction Y, and the corrugated cardboard 100 is conveyed from the first processing area 201 to the second processing area 202 along the width direction W of the corrugated cardboard 100. The dimension of the width direction W is smaller than the dimension of the length direction L, therefore the conveying distance from the first processing area 201 to the second processing area 202, i.e., the conveying time, is shortened. Therefore, according to the processing apparatus 2, by shortening the conveying time between the first and second processing, the time required for one cycle of folding can be shortened, thereby improving the boxing efficiency of the corrugated cardboard 100.

[0100] <Fourth Effect>

[0101] During the transfer from the first processing area 201 to the second processing area 202, the processing device 2 applies adhesive AD to the adhesive sheet 119. Therefore, according to the processing device 2, there is no need to set a time for applying adhesive AD, thus shortening the time required for one cycle of folding and thereby improving the boxing efficiency of the corrugated cardboard 100.

[0102] [Second Embodiment (Processing Device 3):] Figure 9 , Figure 10 , Figure 11 ]

[0103] Next, refer to Figure 9 and Figure 10 The processing apparatus 3 according to the second embodiment will be described.

[0104] In the processing apparatus 2 according to the first embodiment, the corrugated cardboard 100 conveyed along the first direction X to the first processing area 201 is conveyed towards the second processing area 202 along the second direction Y after the first processing is completed. This conveying direction is preferred in the present invention, but the present invention can also be: as in the processing apparatus 3, if the first processing is completed, the corrugated cardboard 100 conveyed along the first direction X to the first processing area 201 is conveyed towards the second processing area 202 along the first direction X. This is the second embodiment. That is, in the second embodiment, the first processing area 201 and the second processing area 202 are arranged along the first direction X.

[0105] [Transfer from Processing Area 1 201 to Processing Area 202: Reference] Figure 9 ]

[0106] In the processing apparatus 3, the first processing region 201 and the second processing region 202 are arranged along the first direction X. The first processing region 201 is located on one side of the upstream U, and the second processing region 202 is located on one side of the downstream D.

[0107] In the first processing area 201, the first processing is performed with the first processing reference position 103 of the corrugated cardboard 100 aligned with the first positioning reference 203. After the first processing, the corrugated cardboard 100 is transferred to the second processing area 202 for the second processing. The second processing is performed with the centerline C of the corrugated cardboard 100 aligned with the second positioning reference 204. When the second processing is performed in the second processing area 202, the first processing reference position 103 of the corrugated cardboard 100 is aligned with the first positioning reference 203.

[0110] The first processing unit 70 includes, for example, a third conveying unit 71 consisting of a conveying device and a third folding machine 73 for folding the corrugated cardboard 100 placed on the third conveying unit 71. Although not shown in the figure, the first processing unit 70 includes a pressing machine that presses the corrugated cardboard 100 when it is folded by the third folding machine 73. The same applies to the second processing unit 80.

[0111] The second processing unit 80 includes, for example, a fourth conveyor unit 81 composed of a conveying device and a fourth folding machine 83 for folding the corrugated cardboard 100 placed on the fourth conveyor unit 81. In the first processing unit 70 and the second processing unit 80, a third folding machine 73 and a fourth folding machine 83 are disposed between the third conveyor unit 71 and the fourth conveyor unit 81. The corrugated cardboard 100 is folded by the third folding machine 73 in the first processing unit 70 and then conveyed to the second processing unit 80, where it is folded by the fourth folding machine 83. Hereinafter, reference will be made to... Figure 10 and Figure 11 The steps of the folding process in the processing device 3 will be explained.

[0112] [ Figure 10 Step 11, Step 12]

[0113] The corrugated cardboard 100 is conveyed by the third conveyor unit 71 until the first processing reference position 103 of the corrugated cardboard 100 (not shown in the figure) aligns with the first positioning reference 203. Then, the first folding piece 114 of the corrugated cardboard 100 is folded by flipping the third folding machine 73.

[0114] [ Figure 11 Steps 13 and 14]

[0115] If the folding of the first fold piece 114 is completed, the corrugated cardboard 100 is conveyed by operating the third conveyor 71 and the fourth conveyor 81 until the third processing reference position 105 is aligned with the third positioning reference 205. If the conveying of the corrugated cardboard 100 is completed, the second fold piece 116 of the corrugated cardboard 100 is folded by rotating the fourth folding machine 83 clockwise as shown in the figure.
