Description
Technical Field
[0001] The present invention relates to a technical field of plate sheet processing, and in particular to a plate sheet bending device capable of avoiding interference between the plate sheet and a folding knife during bending to cause a skewed bending line. Background Art
[0002] Bending is a common process in sheet material processing. For example, to make a carton from cardboard, the cardboard must first be bent at a predetermined position by a bending machine and then assembled into shape. The existing bending machine feeds the cardboard through a folding knife and then pushes the cardboard to bend at the blade of the folding knife.
[0003] However, since the tip of the blade is in an arc shape from a microscopic point of view, when the cardboard contacts the blade of the folding knife, it will bend at the end of the arc of the blade close to its top, so the bending point of the cardboard corresponds to the end of the arc of the blade close to its top. However, after the cardboard is bent, as its bending angle gradually increases, the bent and drooping cardboard part will gradually approach the other end (the lower end) of the arc of the blade of the folding knife and eventually interfere with the other end of the arc of the blade, causing the bending point of the cardboard to be skewed. In this way, the cardboard cannot be made according to the originally designed folding line, which will cause errors in the size or structure of the final product. Summary of the invention
[0004] In view of this, an object of the present invention is to provide a plate sheet bending device, which solves the problem of skewing of the folding line when the plate sheet is bent by a folding knife in the prior art.

The pushing module comprises a pushing member, which is arranged adjacent to the folding knife module, and the angle between the pushing member and the conveying member gradually increases from front to back according to the moving direction of the plate sheet.

[0006] In another embodiment, the folding knife module further includes a first moving mechanism connected to the first position of the folding knife member, so that the portion of the blade corresponding to the first position moves along a third direction, and the third direction is perpendicular to the first direction and the second direction at the same time.

[0011] In another embodiment, the pushing member is a belt-shaped object, and the pushing module further includes a driving wheel and a driven wheel. The pushing member is disposed on the driving wheel and the driven wheel, and the rotating shaft of the driving wheel and the rotating shaft of the driven wheel are disposed perpendicular to each other.
[0012] In another embodiment, the conveying module further includes a plurality of pressing rollers disposed above the conveying member, pressing against the plate sheet to keep the plate sheet on the conveying member.
[0013] In another embodiment, the distance between the portion of the blade portion corresponding to the first position and the portion of the blade portion corresponding to the second position in the second direction is less than 1 / 2 of the thickness of the plate.
[0014] In another embodiment, the front end of the blade portion has a guiding slope, and the plate material moving along the first direction abuts against the guiding slope.

[0091] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , which shows an embodiment of the plate sheet bending device of the present invention. The plate sheet bending device of this embodiment includes a machine platform 10, a conveying module 20, a folding knife module 30, a pushing module 40, a first moving mechanism 50 and a second moving mechanism 60.
[0092] The machine 10 includes a lower machine 11 and an upper machine 12. The lower machine 11 is a platform-like structure, and the conveying module 20, the folding knife module 30, the first moving mechanism 50 and the second moving mechanism 60 are all arranged on the lower machine 11. The upper machine 12 is a long plate-like structure, which forms a mutually perpendicular configuration with the platform structure of the lower machine 11, and the pushing module 40 and part of the conveying module 20 are arranged on the upper machine 12. There is a gap G between the lower machine 11 and the upper machine 12, and the sheet material P can move between the lower machine 11 and the upper machine 12 when being conveyed by the conveying module 20.
[0093] The conveying module 20 includes a conveying member 21 and a driving mechanism 22, and the driving mechanism 22 drives the conveying member 21 to move along a first direction L1. The conveying member 21 of the present embodiment is a conveying belt, and the driving mechanism 22 includes a driving wheel 221, a plurality of transmission rollers 222, a plurality of supporting rollers 223, and a plurality of pressing rollers 224. The conveying belt as the conveying member 21 is arranged on the driving wheel 221, the transmission rollers 222, and the supporting rollers 223, and is driven by the driving wheel 221 to move continuously. The conveying member 21 has a working section arranged on the platform portion 111 of the lower platform 11, and the supporting rollers 223 are arranged on the platform portion 111 of the lower platform 11, and the sheet material P is carried by the conveying member 21 through the platform portion 111 of the lower platform 11. The pressing roller 224 is disposed on the upper machine table 12 and is located at a position corresponding to the supporting roller 223. The sheet material P moves between the supporting roller 223 and the pressing roller 224. The pressing roller 224 can press against the sheet material P to keep the sheet material P on the conveying member 21. Fig.11 As shown, the supporting roller 223 is provided with a convex rib 2231, which can form an indentation on the plate sheet P and pre-indent the predetermined bending position of the plate sheet P, which is beneficial to the subsequent bending process. The driving wheel 221 and the plurality of transmission rollers 222 of this embodiment are arranged on the side 112 of the lower machine 11, and the side 112 is arranged adjacent to the platform part 111. The above-mentioned gap G is formed between the platform part 111 of the lower machine 11 and the upper machine 12, so that the plate sheet P can protrude from the platform part 111 to the side through the gap G when the conveyor 21 moves.
[0094] The folding knife module 30, the first moving mechanism 50 and the second moving mechanism 60 are all arranged on the side 112 of the lower machine table 11. The folding knife module 30 includes a folding knife member 31. The folding knife member 31 is arranged on one side of the conveying member 21 according to the movement of the plate sheet P along the first direction L1. The first moving mechanism 50 is connected to a first position of the folding knife member 31, and the second moving mechanism 60 is connected to a second position of the folding knife member 31. The folding knife member 31 includes a blade portion 311 and a handle portion 312. The blade portion 311 is located on one side of the conveying member 21, and the plate sheet P is bent when the conveying member 21 moves through the blade portion 311. The blade portion 311 of the folding knife member 31 of this embodiment can form an inclination angle θ (such as θ) along a second direction L2 relative to the first direction L1. Fig.13 As shown in FIG. 1 ), the blade portion 311 gradually approaches the conveying module 20 along the moving direction of the plate sheet P. The second direction L2 is perpendicular to the first direction L1. Figure 8 and Fig.13 As shown, the blade portion 311 corresponding to the second position is closer to the conveying member 21 than the blade portion 311 corresponding to the first position, thereby forming a clearance distance D between the front and rear portions of the blade portion 311 corresponding to the first position and the second position.
[0095] Please refer to Figures 1 to 5 , the pushing module 40 is arranged on the upper machine table 12 and close to the above-mentioned gap G. The pushing module 40 includes a pushing member 41, a driving wheel 42 and a driven wheel 43. The pushing member 41 is arranged on the driving wheel 42 and the driven wheel 43. The rotating shaft of the driving wheel 42 and the rotating shaft of the driven wheel 43 are arranged perpendicular to each other. The pushing member 41 of this embodiment is a belt-shaped object, which is arranged adjacent to the folding knife module 30, and the angle between the pushing member 41 and the conveying member 21 gradually increases from front to back according to the moving direction of the plate sheet P, that is, the pushing member 41, which is a belt-shaped object, is twisted from the driving wheel 42 to the driven wheel 43, whereby when the plate sheet P passes through the pushing module 40, the plate sheet P and the pushing member 41 interfere with each other, so that the plate sheet P is bent at the blade portion 311 and the handle portion 321 according to the angle between the pushing member 41 and the conveying member 21.
[0096] See also Figure 6 The first moving mechanism 50 includes a first seat 51, a first cam 52 and a first guide member 53. The first seat 51 is movably disposed on the lower platform 11 and abuts against the first guide surface 531 of the first guide member 53. The first guide surface 531 is parallel to a third direction L3, and the third direction L3 is perpendicular to the first direction L1 and the second direction L2. The first seat 51 has a coupling fork (not shown in the figure), which is clamped on the outer circumference of the first cam 52. The first cam 52 is an eccentric wheel. The distances between each point on the outer circumference of the first cam 52 and the rotating shaft are different. The first cam 52 rotates to drive the first seat 51 to generate a moving stroke. At the same time, the first seat 51 is guided by the first guide surface 531 of the first guide member 53 to move in the third direction L3. The handle portion 312 of the folding knife 31 corresponding to the first position is coupled to the first base 51 , whereby the portion of the folding knife 31 corresponding to the first position moves along with the first base 51 in the third direction L3 .
[0097] See also Figure 7The second moving mechanism 60 includes a second seat 61, a second cam 62 and a second guide member 63. The second seat 61 is movably disposed on the lower platform 11 and abuts against the second guide surface 631 of the second guide member 63. The second guide surface 631 is parallel to a fourth direction L4. The fourth direction L4 is perpendicular to the first direction L1 and has an angle less than 90 degrees with the second direction L2. The second seat 61 has a coupling fork (not shown in the figure), which is clamped on the outer circumference of the second cam 62. The second cam 62 is an eccentric wheel. The distances between each point on the outer circumference of the second cam 62 and the rotating shaft are different. The second seat 61 is driven to generate a moving stroke by the rotation of the second cam 62. At the same time, the second seat 61 is guided by the second guide surface 631 of the second guide member 63 to move in the fourth direction L3. The handle portion 312 of the folding knife 31 corresponding to the second position is coupled to the second base 61, whereby the portion of the folding knife 31 corresponding to the second position moves along the second base 61 in the fourth direction L4. Since the fourth direction L4 and the second direction L2 have an angle less than 90 degrees, the portion of the folding knife 31 corresponding to the second position moves upward along the third direction L3 and also generates a displacement along the second direction L2 and is closer to the conveying member 21.
[0098] in addition, Figure 8 The clearance distance D between the first position and the second position of the blade portion 311 shown is related to the thickness of the plate sheet material. Preferably, the clearance distance D is less than 1 / 2 of the thickness of the plate sheet material P. Therefore, the second guide surface 631 of the second guide member 63 is configured as an inclined surface (the angle with the second direction L2 is less than 90 degrees), so that the moving distance of the portion of the blade portion 311 corresponding to the second position along the third direction L3 (related to the thickness of the plate sheet material P) is linearly related to the clearance distance D generated by the portion of the blade portion 311 corresponding to the second position along the second direction L2, thereby achieving a linear correlation between the clearance distance D and the thickness of the plate sheet material P. Of course, in other embodiments, for different types of plate sheets, the clearance distance D and the thickness of the plate sheet material P may also be nonlinearly related, so the second guide surface 631 of the second guide member 63 may also be configured as a curved surface, so as to achieve a nonlinear correlation between the clearance distance D and the thickness of the plate sheet material P.
[0099] like Fig. 9As shown, in addition to being connected to the folding blade 31 corresponding to the second position, the second moving mechanism 60 of this embodiment can be provided with another third moving mechanism 60' at a third position between the first position and the second position. The third moving mechanism 60' also causes the portion of the blade 311 corresponding to the third position to generate a clearance distance D' along the second direction L2, and the clearance distance D' corresponding to the third position is smaller than the clearance distance D corresponding to the second position, and the angle between the third guide surface 631' of the third guide member 63' of the third moving mechanism 60' and the second direction L2 is larger than the angle between the second guide surface 631 of the second guide member 63 of the second moving mechanism 60 and the second direction L2. The front end of the blade portion 311 of the folding knife member 31 of this embodiment has a guiding slope 319, and the plate sheet P moving along the first direction L1 abuts against the guiding slope 319. The guiding slope 319 enables the plate sheet P to enter the blade portion 311, thereby preventing the plate sheet P from abutting against the front edge of the folding knife member 31 and being unable to smoothly enter the blade portion 311, or even causing damage to the plate sheet P.
[0100] See also Fig.10 A first connecting protrusion 313 is provided at the portion of the folding knife member 31 corresponding to the first position. The first connecting protrusion 313 is disposed in a first accommodating groove 511 of the first seat body 51. The first connecting protrusion 313 has a through hole 314 for a bolt M to pass through and connect the first connecting protrusion 313 and the first seat body 51. The through hole 314 of the present embodiment is a circular hole.
[0101] See also Fig.11 A third connecting protrusion 315 is provided on the portion of the folding knife member 31 corresponding to the third position. The third connecting protrusion 315 is arranged in a third accommodating groove 611' of the third seat body 61'. The third seat body 61' moves along the third guide surface 631' of the third guide member 63'. The third connecting protrusion 315 is provided with a long slot hole 316 for a bolt M to pass through and connect the third connecting protrusion 315 and the third seat body 61'. The long axis direction of the long slot hole 316 of this embodiment is parallel to the first direction L1. The long slot hole 316 can be used for fine-tuning the position of the connecting component during assembly.
[0102] See also Fig.12 A second connecting protrusion 317 is provided on the portion of the folding knife member 31 corresponding to the second position. The second connecting protrusion 317 is arranged in a second accommodating groove 611 of the second seat body 61. The second seat body 61 moves along the second guide surface 631 of the second guide member 63. The second connecting protrusion 317 is provided with a long slot hole 318 for a bolt M to pass through and connect the second connecting protrusion 317 and the second seat body 61. The long axis direction of the long slot hole 318 of this embodiment is parallel to the first direction L1. The long slot hole 318 can be used for fine-tuning the position of the connecting component during assembly.
[0103] See also Fig.14Before the sheet material P enters the folding knife module 30, it will be pre-rolled by a pair of pre-pressing rollers 225 and 226 to produce folds, so as to facilitate the subsequent bending process of the folding knife module 30. The pre-pressing roller 225 is provided with a flat surface 2251, and the pre-pressing roller 226 is provided with a convex rib 2261 on the wheel surface. The flat surface 2251 provides support for the sheet material P, and the convex rib 2261 can form folds on the sheet material P.
[0104] See also Fig.15 and Fig.16 , which respectively represent the states in which the blade portion 311 of the folding knife 31 bends the plate sheet P with smaller thickness and that with larger thickness. For the plate sheet P with larger thickness, the blade portion 311 of the folding knife 31 will move to a higher position along the third direction L3.
[0105] See also Fig.17 and Fig.18 , which indicates the state where the plate sheet P is bent by the folding knife 31. The plate sheet P is bent by the folding knife 31. As the bending angle of the plate sheet P gradually increases, before the plate sheet P interferes with the folding knife 31, the plate sheet P moves through the portion of the blade 311 corresponding to the second position. Since there is a clearance distance D between the portions of the blade 311 corresponding to the first position and the second position, when the plate sheet P passes through the blade 311, due to the clearance distance D generated by the blade 311 between the first position and the second position, when the bending angle of the plate sheet P continues to increase, the plate sheet P will not interfere with the blade 311 and can continue to bend accurately along the original bending position to finally be formed.
[0106] The plate sheet material bending device of the present invention is provided with a folding knife member and a clearance distance is formed between the first position and the second position of the folding knife member, that is, the part of the folding knife member corresponding to the second position is closer to the conveyor belt, so that the plate sheet material just enters the range of the blade part during the movement. Since the blade part corresponding to the second position and the blade part corresponding to the first position have a clearance distance, the plate sheet material will not interfere with the folding knife during the continuous bending process and can be bent accurately according to the predetermined position, so that the final product can be completed accurately according to the designed structure without any error.
