Fig. 1 is a schematic perspective view in a top view of an embodiment of an automatic box folding machine, and fig. 2 is a schematic perspective view in a bottom view of the automatic box folding machine. Referring to fig. 1 and 2, the automatic box folding machine according to the present embodiment includes: the substrate 101, the substrate 101 is provided with a material storage part 100, a material loading part 200, a spreading part 400, a hemming box sealing part 300 and a material unloading part 600. The stock unit 100 is provided above the substrate 101, and a plurality of cassettes (cassette blanks, i.e., cassettes which are not formed by unfolding) 500 are stacked in the Z-axis direction. The loading unit 200 is provided below the storage unit 100, and suctions the lower portion of the box blank and conveys the box blank to the box folding position 102. The opening part 400 is provided above the folding position 102, and upwardly sucks the upper part of the box blank in a state in which the lower part of the box blank is sucked by the feeding part 200, so as to open the box blank. The folded edge sealing part 300 is provided at least at one side of the folded box position 102 for integrally folding and sealing the seal 501 of the opened box blank to form the box 500. The blanking portion 600 conveys the cassette 500 from the cassette folding position 102 and performs blanking.

In the automatic box folding machine of the present embodiment, not only the edge folding and box sealing step can be completed, but also the structure can be simplified. Specifically, for example, by providing the stock unit 100 in which a plurality of box blanks are stacked in the Z-axis direction, the structure of the stock can be simplified, and the structure of the stock can be made more compact. By sucking the box blank at the bottom, the box blank can be kept at a position where it can be sucked by the loading unit 200 by its own weight, and the structure for lifting and lowering the box blank can be omitted. The upper main plate 505 and the lower main plate 506 of the box blank are simultaneously sucked by the feeding part 200 and the spreading part 400 to spread the box blank, so that the seal of the box blank can be easily opened, and the structure is compact. The structure of the edge folding and box sealing can be reduced by integrally completing the edge folding and box sealing of the seal through one edge folding and box sealing part 300, and the structure of the automatic box folding machine can be further simplified.

The following describes each component of the automatic box folding machine in detail.

[ stock Material portion 100]

Fig. 3 is a schematic perspective view of the stock unit 100, and referring to fig. 3, the stock unit 100 is disposed on the substrate 101, specifically, the stock unit 100 includes, for example, a first plate 103 for defining a stock space 106 and second plates 104 located on both sides of the first plate 103 in the X-axis direction. The first plate 103 and the two second plates 104 are connected to each other to form a U-shape. One side of the two second plates 104 in the Y-axis direction is connected to the first plate 103, and the other side is provided with an adjusting plate 105 adjustable in the Y-axis direction. By providing the adjusting plate 105, the size of the storage space 106 can be adjusted according to box blanks of different sizes, so that box blanks of different sizes can be stored.

Further, each of the second plate members 104 is also provided with a support block 107 extending into the storage space 106, and the support blocks 107 are used for supporting box blanks stacked in the up-down direction (Z-axis direction). The height of the support blocks 107 from the base plate 101 is greater than the thickness of the box blank. After the loading portion 200 is sucked to the box blank, the box blank is pulled downward, whereby the box blank is deformed and straddles the supporting block 107. The loading section 200 then transfers the cassette blank to the tuck position 102. In this embodiment, since the supporting block 107 is provided, and the box blank can cross the supporting block 107 when being pulled down, not only is the feeding easy, but also the initial position of the box blank during the feeding can be ensured, so that a complex feeding structure can be omitted, and the structure of the automatic box folding machine can be simplified.

[ feeding portion 200]

Fig. 4 is a schematic perspective view of the feeding portion 200, referring to fig. 4 with additional reference to fig. 2, in some embodiments, the feeding portion 200 includes: a first adsorbing member 201, a first adsorbing member driving section 202, and a feeding driving section 203. Wherein the first suction member 201 sucks the lower portion of the box blank. The first suction member driving section 202 drives the first suction member 201 in the Z-axis direction. The feeding driving portion 203 drives the first adsorbing member driving portion 202 and the first adsorbing member 201 in the Y-axis direction. Specifically, the loading unit 200 is disposed below the substrate 101, and the first suction member 201 may be, for example, a vacuum chuck or a vacuum plate, and the substrate 101 is provided with a first escape groove 108 (see fig. 2), and the first suction member 201 penetrates the first escape groove 108 to suck the cassette blank. The first suction member driving section 202 may select, for example, an air cylinder, thereby driving the first suction member 201 to rise and fall. When the first suction member 201 is lifted, the box blank is sucked, and when the first suction member 201 is lowered, the box blank is deformed so as to cross the supporting block 107, and the box blank can be easily transported. The feeding drive section 203 can select, for example, a combination of a motor and a timing belt conveying mechanism, whereby the cassette blank can be easily transferred to the cassette folding position 102 in the Y-axis direction.

[ Prop-off portion 400]

Fig. 5 is a schematic perspective view of the spreader portion 400 and the blanking portion 600, and referring to fig. 5, in some embodiments, the spreader portion 400 includes: a second absorbing member 401, a spreader driving portion 402, and an elastic buffer portion 403. Wherein the second suction member 401 sucks the upper portion of the cassette blank. The opening drive section 402 drives the second adsorbing member 401 obliquely upward in the Y-axis direction. The elastic buffer 403 connects the second suction member 401 and the expansion driving member 402, and is stretchable in the Z-axis direction. Specifically, the second suction member 401 is, for example, a vacuum chuck or a vacuum plate. The opening drive unit 402 may be, for example, an air cylinder, and the air cylinder of the opening drive unit 402 is driven to incline upward in the Y-axis direction in order to simulate the opening operation of the folding box. The elastic buffer 403 includes a telescopic rod 404 and a buffer spring 405, the second absorber 401 is connected to the cylinder of the spreader driving part 402 through the telescopic rod 404, and the second absorber 401 is cushionable in the Z-axis direction by the buffer spring 405. Accordingly, the second suction member 401 can be adapted in the Z-axis direction in accordance with the driving operation of the cylinder of the expansion driving unit 402, and the cassette blank can be reliably sucked.

By providing the first suction member 201 that sucks the lower portion of the box blank and the second suction member 401 that sucks the upper portion of the box blank and driving the second suction member 401 by the opening driving portion 402 to extend obliquely upward in the Y-axis direction, the opening operation of the box blank can be simulated, and the box can be easily opened.

[ hemming box sealing portion 300]

After the box blank is opened by the suction of the first suction member 201 and the second suction member 401, the hemming of the seal 501 of the box 500 can be performed. As described above, the hemming-sealing portion 300 is provided at least at one side of the hemming position 102 for integrally hemming and sealing the seal of the opened box blank to form the box 500.

Fig. 6 is a top view of one embodiment of hemmed box portion 300 (having second box portion 323, described later), fig. 7 is a bottom view of hemmed box portion 300, and fig. 8 is a top view of another view of hemmed box portion 300 (second box portion 323 is omitted). Fig. 9 is a schematic view of the hemmed box portion 300 in a state where the cover plate 503 is hemmed.

Referring to fig. 6-9, the hemmed box portion 300 is for hemming and sealing a seal 501 of a box 500, and includes: the first driving part 301 that drives in the X-axis direction, the two flap hemming members 302 that hem the two flaps 502, the insert panel hemming part 303 that hem the insert panel 504, and the first box sealing part 304 that hem the cover panel 503 and seal the seal 501.

Wherein, two flap hemming members 302 are respectively located at two sides of the Y-axis direction of the seal 501, and are respectively connected with the first driving portion 301 through the connecting rod portion 305, and extend and retract along the Y-axis direction along with the driving of the first driving portion 301 along the X-axis direction, so as to hem the two flaps 502.

The board folding part 303 is disposed at one side of the seal 501 in the X-axis direction, and has a board folding part 306 and a torsion spring part 307, the torsion spring part 307 abuts against the board folding part 306, and when the first driving part 301 is driven towards the seal 501 in the X-axis direction, the board folding part 306 is driven by the torsion spring part 307 to swing towards the first direction (clockwise direction in the drawing) to fold the board 504.

The first box portion 304 is disposed on one side of the seal 501 in the X-axis direction and connected to the first driving portion 301, the first box portion 304 has a cover flange member 308 and a Z-axis limiting member 309, the cover flange member 308 is driven by the first driving portion 301 to approach the seal 501 in the X-axis direction to flange the cover 503, and the Z-axis limiting member 309 is disposed to limit a position of the insert plate 504 in the Z-axis direction so that the insert plate 504 is inserted into the seal 501 as the cover 503 is flange-folded.

In the hemming box portion 300 of the present embodiment, the number of driving elements can be reduced, and thus the structure can be simplified. Specifically, since the first driving portion 301 drives the two flap hemming members 302 to hem the two flaps 502 of the box 500 while driving in the X-axis direction. And, the board hemming member 306 is released and driven by the torsion spring member 307 to hem the board 504. Further, the first sealing part 304 is connected to the first sealing part 304, and the first sealing part 304 folds the cover plate 503 and seals the seal 501. That is, the first driving unit 301 can realize a combined operation by combining other mechanical mechanisms (for example, the link unit 305 and the torsion spring 307), thereby reducing the number of driving elements and simplifying the structure. And further, the cost can be reduced, and the maintenance of the device is convenient.

Referring to fig. 6, the cassette 500 is held on the substrate 101 in an open state, that is, the cassette 500 is held on the substrate 101 in a shape of a substantially rectangular parallelepiped, for example, as a main body thereof. This facilitates folding of the flap 502, the cover 503, and the insert 504. The folded edge seal box portion 300 is also mounted on the substrate 101 opposite the seal 501 of the box 500.

Referring to fig. 6 and 7, in some embodiments, the first driving part 301 includes a first driving element 310 and a first mounting base 311, and the first driving element 310 and the first mounting base 311 are connected and drive the first mounting base 311 to slide in the X-axis direction. Specifically, the first driving member 310 may be a cylinder or a motor, and the cylinder is preferable from the viewpoint of cost. The first mounting base 311 is mounted on a first linear slide assembly 312 that is oriented in the X-axis direction. Thus, the first mounting base 311 can slide in the X-axis direction along with the slider of the first linear slide rail assembly 312.

Referring to fig. 6, 8 and 9, the link portion 305 includes two places, one link portion 305 connecting one flap hemming member 302 and the first driving portion 301, and the other link portion 305 connecting the other flap hemming member 302 and the first driving portion 301. The configuration of the two link portions 305 is substantially the same, and one of the link portions 305 will be described as an example.

In some embodiments, the shaft portion 305 includes: a first slider 313 and a link 314. The flap hemming member 302 is provided at a first slider 313, and the first slider 313 is slidable in the Y-axis direction. One end of the link member 314 is connected to the first mounting base 311, and the other end is connected to the first slider 313. The link member 314 is driven in the X-axis direction by the first driving unit 301 toward the seal 501, and thereby slides the first slider 313 in a telescopic manner in the Y-axis direction. Specifically, the first slider 313 is mounted on the second linear slide rail assembly 315 that is guided in the Y-axis direction. Thus, the first slider 313 can slide in the Y-axis direction along with the slider of the second linear slide rail assembly 315. Flap hemming member 302 may be either locked to first slider 313 by, for example, a screw or integrally formed with first slider 313. From the viewpoints of cost reduction and simplification of the structure of the parts, the flap hemming member 302 is preferably screwed to the first slider 313.

One end of the link member 314 is mounted to the first mounting base 311 by a screw, and the mounting position of one end of the link member 314 with respect to the first mounting base 311 is adjustable in the X-axis direction. Thereby, the positional relationship between the first mounting base 311 and the first slider 313 can be adjusted as needed, so that the position and distance of the first slider 313 along the Y-axis direction along with the movement of the first mounting base 311 in the X-axis direction can be adjusted.

In this process in which the cylinder as the first driving member 310 drives the first mounting base 311 to protrude toward the seal 501 of the box 500 in the X-axis direction, the first slider 313 (flap hemming member 302) is subjected to a process of protruding toward the seal 501 in the Y-axis direction and then retracting. That is, the first slider 313 (flap hemming member 302) first protrudes from the initial position in the Y-axis direction toward the seal 501 of the box 500, and hemms the flap 502 of the seal 501. Then, it is retracted in the Y-axis direction from the seal 501 of the cassette 500, thereby facilitating the hemming of the cover plate 503.

In some embodiments, in order to extend and retract the first slider 313 (flap hemming member 302) with respect to one of the first mounting bases 311, the first slider 313 is provided with a first guide portion 316 having an arc shape, and a distance in the X-axis direction of the first guide portion 316 with respect to the Y-axis direction at the seal 501 is greater than a distance in the Y-axis direction of both ends of the first guide portion 316 with respect to the seal 501. The link member 314 slides along the first guide 316.

Specifically, the first guide 316 includes, for example, a guide groove 317 formed in the first slider 313. The track of the guide groove 317 is substantially semicircular or slightly smaller than semicircular. The middle of the guide groove 317, i.e., the middle of the guide groove 317 in the X-axis direction, is the greatest distance from the seal 501 in the Y-axis direction. One end of the link member 314 may be provided with a roller 318, and the roller 318 is received in the guide groove 317 and slides along the guide groove 317. When the first mounting base 311 is at the initial position, the roller 318 of the link member 314 is at one end of the guide groove 317 in the X-axis direction away from the seal 501. When the first mounting base 311 protrudes toward the seal 501 of the box 500 in the X-axis direction, the roller 318 of the link member 314 slides in the guide groove 317. Since the guide groove 317 is arc-shaped, the link member 314 pushes the first slider 313 through the second linear slide rail assembly 315 while moving in the X-axis direction, thereby sliding in the Y-axis direction. At the same time, the flap hemming member 302 gradually approaches the seal 501 of the box 500 in the Y-axis direction and hemms it against the flap 502 at the seal 501. When the roller 318 of the link member 314 slides to the middle of the guide groove 317 (i.e., the position at the greatest distance from the seal 501 in the Y-axis direction), the flap hemming member 302 also reaches the protruding limit position in the Y-axis direction. Then, as the roller 318 of the link member 314 extends from the middle of the guide groove 317 toward the other end of the guide groove 317 (the end near the seal 501), the flap hemming member 302 also moves in the Y-axis direction toward a position away from the seal 501 of the box 500. Thus, the flap hemming member 302 is retracted from the seal 501 of the box 500 after the flap 502 is hemmed.

In the present embodiment, by providing the guide groove 317 having an arc shape, the operation of extending and retracting the flap hemming member 302 can be easily performed by only one operation (for example, an extending operation) of the first driving member 310, and not only the hemming operation of the flap 502 of the cassette 500 can be completely and efficiently performed, but also the structure is simple and compact, and the control is simple without adding an additional driving member. Further, the cost of the apparatus can be reduced.

In the above, the guide groove 317 has been described as an example of the first guide portion 316, but the present invention is not limited thereto. For example, a cam (not shown) or another link hinged to the link member 314 may be provided to the first slider 313.

Referring to fig. 7, with additional reference to fig. 3, as described above, the board folding portion 303 is provided on one side in the X-axis direction of the seal 501, and when the first driving portion 301 is driven in the X-axis direction toward the seal 501, the board folding piece 306 is driven by the torsion spring member 307 to swing in the first direction (clockwise direction in the drawing) to fold the board 504. Specifically, the board edge folding member 306 is swingably mounted to the base board 101, and one end of the torsion spring member 307 abuts against the board edge folding member 306 and the other end abuts against the base board 101. Box 500 is also held on base plate 101 with insert plate 504 at seal 501 of box 500 above insert plate hemming member 306 with insert plate hemming member 306 restrained. First mounting base 311 is provided with, for example, drive plate 319, and when first mounting base 311 is in the initial position, drive plate 319 presses against fork strap section 306 such that the swing of fork strap section 306 is limited. When first drive element 310 drives first mounting base 311 in the X-axis direction toward seal 501, drive plate 319 releases the restriction of insert plate hemming member 306, and insert plate hemming member 306 swings under the influence of torsion spring member 307. This enables the insert plate 504 to be folded. When the first driving portion 301 is driven in a direction away from the seal 501, the fork strap hemming member 306 is driven by the first driving portion 301 to swing in a second direction (counterclockwise in the drawing) opposite to the first direction. I.e., drive plate 319 is driven back to the original position and presses against fork strap hemming member 306.

Thus, in this embodiment, the first driving member 310 is driven while releasing or restricting the board hemming member 306, so that the hemming operation of the board 504 connected to the cover 503 of the box 500 can be completely and efficiently performed, and the structure is simple and compact.

That is, in the present embodiment, as the first mounting base 311 approaches toward the seal 501 of the box 500 in the X-axis direction, the drive plate 319 releases the restriction of the insert plate hemming member 306, and the flap hemming member 302 hemms the flap 502. In this process, it is necessary to provide timing at which the drive plate 319 releases the restriction on the insert panel hemming member 306, and timing at which the flap hemming member 302 hemms the flap 502. Specifically, by adjusting the mounting position of the link member 314 on the first mounting base 311, the timing at which the drive plate 319 releases the restriction on the insert plate hemming member 306 and the timing at which the flap hemming member 302 hemms the flap 502 are set. For example, by adjusting the position of link member 314, flap hemming member 302 is caused to hem flap 502 for a period of time that precedes the period of time that drive plate 319 releases the restriction of insert panel hemming member 306. That is, after flap hemming member 302 begins to hem flap 502, drive plate 319 begins to unblock insert hemming member 306, causing insert hemming member 306 to swing clockwise to hem insert 504.

In addition, it should be noted that, at the same time as flap hemming member 302 begins to hem flap 502, insert panel hemming member 306 also hem insert panel 504. This allows for increased efficiency and also prevents the cover plate 503 from tilting when the insert plate 504 is folded by the insert plate folding piece 306. Specifically, the flap hemming member 302 includes a restricting portion 320 (see fig. 8 and 10 for assistance) at one end of the flap 502 that is hemmed, and the restricting portion 320 restricts the cover plate 503 in the Z-axis direction while the flap hemming member 302 hemms the flap 502. The restricting portion 320 includes, for example, a protruding block provided at one end of the flap hemming member 302, the protruding block being located above the cover plate 503 while the flap hemming member 302 is extended. Thus, the cover plate 503 can be prevented from tilting when the board 504 is folded by the board folding piece 306.

Fig. 10 is a partially enlarged view at a in fig. 9, and with reference to fig. 10 and with continuing reference to fig. 8 and 9, as described above, the first box portion 304 has the cover flange member 308 and the Z-axis restriction member 309, the cover flange member 308 is driven by the first driving portion 301 to approach the seal 501 in the X-axis direction to flange the cover 503, and the Z-axis restriction member 309 is provided to restrict the position of the insert plate 504 in the Z-axis direction so that the insert plate 504 is inserted into the seal 501 as the cover 503 is flange-folded.

Specifically, the cover hemming member 308 is also mounted to the first mounting base 311, moving in the X-axis direction with the first mounting base 311. In order to perform reliable hemming on the cover plate 503, the cover plate hemming member 308 is provided with an arc-shaped second guide portion 321 at an end opposite to the cover plate 503, and the cover plate hemming member 308 pushes the cover plate 503 to slide along the second guide portion 321 so that the cover plate 503 is folded in the Z-axis direction. The second guide portion 321 includes, for example, an arcuate guide surface provided at the rear surface of the drive plate 319. I.e. the guiding surface abuts the cover plate 503 (in particular the connection of the cover plate 503 and the insert plate 504) after the drive plate 319 has released the restriction of the insert plate hemming member 306 to hem the insert plate 504 by the insert plate hemming member 306.

Further, by adjusting the position of the link member 314, the guide surface as the second guide portion 321 is brought into contact with the cover plate 503 after the roller 318 of the link member 314 rides over the middle portion of the guide groove 317 of the first slider 313. That is, the guide surface abuts against the cover plate 503 after the flap hemming member 302 completes hemming the flap 502, and is retracted from the seal 501 of the box 500 to release the restriction of the cover plate 503 by the restriction portion 320 of the flap hemming member 302. After the guide surface abuts the cover plate 503, the cover plate 503 slides along the guide surface and swings (e.g., clockwise) with respect to the seal 501 as the cover plate hemming member 308 continues to be fed in the X-axis direction. Thereby, the cover plate 503 can be hemmed.

A Z-axis limiter 309 may be mounted above the cover flange 308 to inhibit the Z-axis height of the insert plate 504 that swings as the seal 501 swings. The height of the Z-axis limiter 309 in the Z-axis direction is lower than the upper portion of the seal 501, thereby ensuring that the highest height of the insert plate 504 is within the range of the seal 501 so as to be able to be inserted into the seal 501.

In some embodiments, since the height of the board 504 in the Z-axis direction varies continuously as it slides along the guide surface as the second guide portion 321, in order to prevent the Z-axis limiter 309 from pressing the cover 503 or the board 504 in the Z-axis direction, the Z-axis limiter 309 is disposed above the Z-axis direction of the second guide portion 321 and slidable in the Z-axis direction. Specifically, for example, the Z-axis limiter 309 may be mounted above the deck hemming member 308 by a slide shaft 322, and when the deck 503 swings, the Z-axis limiter 309 adaptively slides in the Z-axis direction according to the swing of the deck 503, thereby preventing the deck 503 or the board 504 from being pressed while limiting the height of the board 504. The insert plate 504 is gradually inserted into the closure 501 as the cover plate 503 is pushed by the cover plate hemming member 308 by the restriction of the Z-axis restriction member 309.

Thereby, the sealing of the box 500 at the seal 501 can be completed.

With continued reference to fig. 6 and 9, in addition, although the closure 501 of the cassette 500 can be sealed by the cover flange member 308 and the Z-axis limiter 309, there may be cases where the cover 503 does not completely seal the closure 501. In some embodiments, in order for the cover plate 503 to reliably seal the seal 501, a second box portion 323 is further included, the second box portion 323 being mounted on the first mounting base 311, the second box portion 323 having: the second driving element 324 and the sealing box 325, the second driving element 324 drives the sealing box 325 to stretch along the X-axis direction, and in the state that the plugboard 504 is inserted into the seal 501, the sealing box 325 pushes the cover plate 503 so that the cover plate 503 covers the seal 501. Specifically, the second driving member 324 is, for example, a selection cylinder, and the closure member 325 is located behind the second guide 321 of the cover flange member 308 in the initial state, and after the cover flange member 308 completes the flange of the cover 503, the closure member 325 is driven by the second driving member 324 and pushes the cover 503 to swing further with respect to the closure 501 of the box 500. This can further reliably seal the cover plate 503 to the seal 501.

With continued reference to fig. 8, in some embodiments, to make the structure more compact, the cover flange member 308 is provided with a third guide portion 326 extending in the X-axis direction, and the third guide portion 326 guides the box seal member 325. The third guide 326 is, for example, a guide groove or a guide hole formed in the cover flange 308, and guides the box seal 325.

Hereinafter, the operation flow of the hemming box 300 of the present embodiment will be described. Specifically, the hemming box section 300 performs the steps of:

s10, the first driving element 310 is driven towards the seal 501 of the box 500 along the X-axis direction, and the first mounting base 311 slides linearly along the X-axis direction.

S11: the flap hemming member 302 linearly slides in the Y-axis direction by the driving of the link member 314 and hemms the flap 502 of the seal 501 of the box 500.

S12: after flap hemming member 302 begins hemming flap 502, drive plate 319 begins to unblock insert hemming member 306 and insert hemming member 306 hemms insert 504.

S13: after flap hemming member 302 completes the hemming operation of flap 502, flap hemming member 302 is retracted from seal 501 of box 500 by the actuation of link member 314;

s14: the cover hemming member 308 abuts against the cover 503 as the first mounting base 311 slides, and hemms the cover 503 while the Z-axis restricting member 309 restricts the height of the insert plate 504 so that the insert plate 504 is inserted into the seal 501.

S15: the second driving element 324 drives the sealing member 325 to abut against the cover plate 503, so that the cover plate 503 completely seals the seal 501.

Thereby, the hemming seal of the seal 501 to one side of the box 500 is completed.
