[ distracting part 400]

Fig. 5 is a schematic perspective view of spreader portion 400 and blanking portion 600, and referring to fig. 5, in some embodiments, spreader portion 400 includes: a second suction member 401, a distraction drive section 402, and an elastic buffer section 403. Wherein the second suction member 401 sucks the upper portion of the box blank. The expansion drive unit 402 drives the second suction member 401 obliquely upward in the Y-axis direction. The elastic buffer 403 is connected to the second suction member 401 and the expansion drive unit 402, and is stretchable in the Z-axis direction. Specifically, the second suction member 401 is, for example, a vacuum cup or a vacuum plate. For example, an air cylinder may be selected as the expanding drive unit 402, and the air cylinder of the expanding drive unit 402 is driven to be inclined upward in the Y-axis direction in order to simulate the expanding operation of the folder. The elastic buffer portion 403 includes an expansion link 404 and a buffer spring 405, the second suction member 401 is connected to the cylinder of the expansion drive portion 402 through the expansion link 404, and the second suction member 401 is cushioned in the Z-axis direction by the buffer spring 405. Thus, the second suction tool 401 can be adapted in the Z-axis direction by the driving operation of the air cylinder of the expansion driving unit 402, and can reliably suck the box material.

By providing the first suction member 201 for sucking the lower portion of the box blank and the second suction member 401 for sucking the upper portion of the box blank, and by extending the second suction member 401 obliquely upward in the Y-axis direction by being driven by the expanding drive unit 402, the box can be easily expanded by simulating the expanding operation of the box blank.

[ Flanging case sealing part 300]

After the box blank is spread by the suction of the first suction tool 201 and the second suction tool 401, the seal 501 of the box 500 can be hemmed. As described above, the folding and sealing portion 300 is provided at least on one side of the folding position 102, and integrally folds and seals the seal of the opened box blank to form the box 500.

Fig. 6 is a plan view of an embodiment of the hemmed box portion 300 (having a second box portion 323, described later), fig. 7 is a bottom view of the hemmed box portion 300, and fig. 8 is a plan view of the hemmed box portion 300 (omitting the second box portion 323) from another view. Fig. 9 is a schematic view of the hemming-seal box section 300 in a state of hemming the cover plate 503.

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

The two flap folding pieces 302 are respectively located on two sides of the seal 501 in the Y-axis direction, and are respectively connected to the first driving portion 301 through the link portion 305, and extend and retract in the Y-axis direction along with the driving of the first driving portion 301 in the X-axis direction, so as to fold the two flaps 502.

Here, board folding portion 303 is provided on one side of seal 501 in the X-axis direction, and includes board folding piece 306 and torsion spring piece 307, torsion spring piece 307 abuts board folding piece 306, and when first driving portion 301 is driven toward seal 501 in the X-axis direction, board folding piece 306 is driven by torsion spring piece 307 to swing in the first direction (clockwise direction in the drawing) to fold board 504.

The first box-sealing part 304 is arranged on one side of the seal 501 in the X-axis direction and connected with the first driving part 301, the first box-sealing part 304 is provided with a cover folding piece 308 and a Z-axis limiting piece 309, the cover folding piece 308 is driven by the first driving part 301 to approach the seal 501 along the X-axis direction so as to fold the cover 503, and the Z-axis limiting piece 309 is arranged to limit the position of the insert plate 504 in the Z-axis direction so that the insert plate 504 is inserted into the seal 501 along with the folded cover 503.

In the hem seal box part 300 of the present embodiment, the number of driving elements can be reduced, and therefore the structure can be simplified. Specifically, since the first driving portion 301 drives the two flap folders 302 to fold the two flaps 502 of the cassette 500 while driving in the X-axis direction. And plate hemmer 306 is released and driven by torsion spring 307 to hem plate 504. Further, the first box sealing portion 304 is connected to the first box sealing portion 304, and the first box sealing portion 304 is folded toward the cover 503 and seals the seal 501. That is, the first driving unit 301 can be combined with other mechanical mechanisms (for example, the link unit 305 and the torsion spring 307) to reduce the number of driving elements and simplify the structure. And then can reduce cost, be convenient for the maintenance of device simultaneously.

Referring to fig. 6, the cartridge 500 is held on the substrate 101 in an open state, that is, the cartridge 500 is held on the substrate 101 with its main body substantially in the shape of, for example, a rectangular parallelepiped. This facilitates folding of the flap 502, the lid plate 503, and the insert plate 504. The folded edge seal box portion 300 is also mounted on the base plate 101 and faces 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 along the X-axis direction. Specifically, the first driving element 310 may be selected from a cylinder or a motor, and a cylinder is preferable from the viewpoint of cost. The first mounting base 311 is mounted on a first linear slide assembly 312 that is guided in the X-axis direction. Thereby, the first mounting base 311 can slide along the X-axis direction along with the slider of the first linear guide assembly 312.

Referring to fig. 6, 8 and 9, the link portion 305 includes two positions, one position where the link portion 305 connects one flap folder 302 and the first driving portion 301, and the other position where the link portion 305 connects the other flap folder 302 and the first driving portion 301. The two link portions 305 have substantially the same structure, and one link portion 305 will be described as an example.

In some embodiments, the link portion 305 includes: a first slider 313 and a link 314. The flap folder 302 is provided on a first slider 313, and the first slider 313 is slidable in the Y-axis direction. The link member 314 has one end connected to the first mounting base 311 and the other end connected to the first slider 313. The link member 314 slides the first slider 313 in an extensible manner in the Y-axis direction as it is driven toward the seal 501 in the X-axis direction by the first driving unit 301. Specifically, the first slider 313 is mounted on a second linear slide assembly 315 that is guided in the Y-axis direction. Thereby, the first slider 313 can slide along the Y-axis direction along with the slider of the second linear slide assembly 315. The flap flange 302 can be either fastened to the first slide member 313 by, for example, screws, or can be integrally formed with the first slide member 313. The flap folding piece 302 is preferably fastened to the first slide 313 by screws from the viewpoint of cost reduction and simplification of the structure of parts.

One end of the link member 314 is mounted to the first mounting base 311 by a screw, and the mounting position of the 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, thereby adjusting the position and distance by which the first slider 313 moves in the Y-axis direction in accordance with the movement of the first mounting base 311 in the X-axis direction.

In this process in which the air cylinder as the first driving member 310 drives the first mounting base 311 to extend toward the seal 501 of the cassette 500 in the X-axis direction, the first slider 313 (flap folder 302) goes through a process of extending toward the seal 501 in the Y-axis direction and then retracting. That is, the first slider 313 (flap folder 302) first projects from the initial position in the Y-axis direction toward the flap 501 of the box 500, and folds the flap 502 of the flap 501. And then withdrawn from the seal 501 of the cassette 500 in the Y-axis direction to facilitate folding of the cover plate 503.

In some embodiments, in order to achieve the expansion and contraction of the first slider 313 (flap folder 302) with respect to one of the extending movements of the first mounting base 311, the first slider 313 is provided with a first guide portion 316 having an arc shape, and a distance of a middle portion of the first guide portion 316 in the X-axis direction with respect to the Y-axis direction at the seal 501 is larger than a distance of both ends of the first guide portion 316 in the X-axis direction with respect to the Y-axis direction at the seal 501. The link member 314 slides along the first guide 316.

Specifically, the first guide portion 316 includes, for example, a guide groove 317 opened 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 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 away from the opening seal 501 in the X-axis direction. When the first mounting base 311 is extended toward the seal 501 of the cartridge 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 has a circular arc shape, the link 314 pushes the first slider 313 to slide in the Y-axis direction through the second linear guide assembly 315 while moving in the X-axis direction. Meanwhile, the flap folder 302 gradually approaches the seal 501 of the box 500 in the Y-axis direction, and abuts against the flap 502 at the seal 501 to fold it. When the roller 318 of the link member 314 slides to the middle of the guide groove 317 (i.e., the position where the distance from the flap 501 in the Y-axis direction is the largest), the flap folding member 302 also reaches the extended 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 flap 501), the flap folding member 302 also moves in the Y-axis direction toward a position away from the flap 501 of the box 500. Thus, the flap folder 302 retracts from the seal 501 of the box 500 after the flap 502 is folded.

In the present embodiment, by providing the guide groove 317 having an arc shape, the operation of extending and retracting the flap hemmer 302 can be easily realized by only one operation (e.g., 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 realized, but also no additional driving member is required, the structure is simple and compact, and the control is also simple. Further, the apparatus cost can be reduced.

Although the guide groove 317 has been described as the first guide 316, the present invention is not limited to this. For example, a cam (not shown) or another link hinged to the link 314 may be provided on the first slider 313.

Referring to fig. 7, with reference to fig. 3, as described above, board folding edge portion 303 is provided on one side of seal 501 in the X-axis direction, and when first driving portion 301 is driven toward seal 501 in the X-axis direction, board folding edge piece 306 is driven by torsion spring piece 307 to swing in the first direction (clockwise in the drawing) to fold board 504. Specifically, board break 306 is swingably mounted to base plate 101, and one end of torsion spring 307 abuts board break 306 and the other end abuts base plate 101. Cassette 500 is also held on base 101 with insert plate hem 306 restrained, with insert plate 504 at seal 501 of cassette 500 positioned above insert plate hem 306. For example, drive plate 319 is mounted on first mounting base 311, and when first mounting base 311 is in the initial position, drive plate 319 presses insertion plate hemming member 306 so that swinging movement of insertion plate hemming member 306 is restricted. When first drive element 310 drives first mounting base 311 in the X-axis direction toward seal 501, drive plate 319 releases the restraint of fork strap folding member 306 and fork strap folding member 306 swings under the action of torsion spring member 307. This allows the insert plate 504 to be folded. When the first driving portion 301 is driven in a direction away from the seal 501, the board folding member 306 is driven by the first driving portion 301 to swing in a second direction (counterclockwise direction in the drawing) opposite to the first direction. I.e. drive plate 319 is driven back to the initial position and pressed against flashboard crimping piece 306.

Thus, in the present embodiment, the first driving element 310 can drive and release or restrict the insert plate hemming member 306, so that the hemming operation of the insert plate 504 connected to the cover plate 503 of the cassette 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 the seal 501 of the cassette 500 in the X-axis direction, the driving board 319 releases the restriction of the insertion board folder 306, and the flap folder 302 folds the flap 502. In this process, it is necessary to set a timing at which the driving board 319 releases the restriction of the insertion board hemmer 306 and a timing at which the flap hemmer 302 hems the flap 502. Specifically, by adjusting the mounting position of the link 314 to the first mounting base 311, the timing when the driving plate 319 releases the restriction of the insertion plate hemer 306 and the timing when the flap hemer 302 hems the flap 502 are set. For example, by adjusting the position of the link member 314, the time for the flap hemmer 302 to hem the flap 502 is earlier than the time for the drive plate 319 to release the restriction on the insertion plate hemmer 306. That is, after the flap hemmer 302 starts to hem the flap 502, the driving plate 319 starts to release the restriction of the insertion plate hemmer 306, and swings the insertion plate hemmer 306 clockwise to hem the insertion plate 504.

Further, it should be noted that while flap hemmer 302 begins to hem flap 502, insert hemmer 306 also hems insert 504. This is in addition to allowing for improved efficiency, and also to prevent cover plate 503 from lifting when insert plate hemmer 306 hems insert plate 504. Specifically, the flap folding member 302 is provided with a restricting portion 320 (see fig. 8 and 10 for assistance) at one end of the flap 502 for folding, and the restricting portion 320 restricts the cover plate 503 in the Z-axis direction while the flap folding member 302 folds the flap 502. The restriction portion 320 includes, for example, a protruding piece provided at one end of the flap folder 302, and the protruding piece is located above the cover plate 503 while the flap folder 302 is extended. This prevents the cover plate 503 from being lifted when the insert folding piece 306 folds the insert 504.

Fig. 10 is a partially enlarged view of a portion a in fig. 9, with reference to fig. 10 and with continued reference to fig. 8 and 9, as described above, the first box section 304 has the cover folding piece 308 and the Z-axis restricting piece 309, the cover folding piece 308 is driven by the first driving section 301 to approach toward the seal 501 in the X-axis direction to fold the cover 503, and the Z-axis restricting piece 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 plate 503 is folded.

Specifically, the cover folder 308 is also attached to the first mounting base 311, and moves in the X-axis direction along with the first mounting base 311. In order to reliably fold the cover plate 503, the cover plate folding member 308 is provided with a second guide 321 having an arc shape at an end opposite to the cover plate 503, and the cover plate folding member 308 pushes the cover plate 503 to slide along the second guide 321, so that the cover plate 503 is folded in the Z-axis direction. The second guide portion 321 includes, for example, a guide surface in a circular arc shape, and the guide surface is provided behind the driving plate 319. That is, the guide surface abuts the cover plate 503 (specifically, the joint between the cover plate 503 and the insert plate 504) after the drive plate 319 releases the restriction of the insert plate hemming member 306 so that the insert plate hemming member 306 hems the insert plate 504.

Note that, by adjusting the position of the link 314, the guide surface as the second guide portion 321 abuts on the cover plate 503 after the roller 318 of the link 314 rides over the middle portion of the guide groove 317 of the first slider 313. That is, the guide surface abuts the cover plate 503 after the flap folding member 302 finishes folding the flap 502, retracts from the seal 501 of the cassette 500, and releases the restriction of the cover plate 503 by the restriction portion 320 of the flap folding member 302. After the guide surface abuts the cover 503, the cover 503 slides along the guide surface and swings (e.g., clockwise) relative to the seal 501 as the cover folder 308 is further fed in the X-axis direction. This allows the cover 503 to be folded.

The Z-axis restricting member 309 may be mounted above the cover flap member 308 to suppress the height of the insert plate 504 in the Z-axis direction that swings as the seal 501 swings. The height of the Z-axis restricting member 309 in the Z-axis direction is lower than the position of 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 inserted into the seal 501.

In some embodiments, since the height of the insert plate 504 in the Z-axis direction changes constantly while sliding along the guide surface as the second guide portion 321, in order to prevent the Z-axis restriction member 309 from pressing the cover plate 503 or the insert plate 504 in the Z-axis direction, the Z-axis restriction member 309 is provided above the Z-axis direction of the second guide portion 321 and is slidable in the Z-axis direction. Specifically, for example, the Z-axis restriction member 309 may be attached above the cover flap 308 via the slide shaft 322, and when the cover plate 503 swings, the Z-axis restriction member 309 slides adaptively in the Z-axis direction in accordance with the swing of the cover plate 503, thereby preventing the cover plate 503 or the insert plate 504 from being pressed while restricting the height of the insert plate 504. By the restriction of the Z-axis restricting member 309, the insert plate 504 is gradually inserted into the seal 501 as the cover plate 503 is pushed by the cover plate flange member 308.

This completes the sealing of the seal 501 of the cartridge 500.

With continued reference to fig. 6 and 9, further, while the closure 501 of the cassette 500 can be sealed by the cover flap 308 and the Z-axis limiter 309, there may be instances 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, the sealing device further includes a second sealing box part 323, the second sealing box part 323 is mounted on the first mounting base 311, and the second sealing box part 323 has: a second driving element 324 and a sealing member 325, wherein the second driving element 324 drives the sealing member 325 to extend and retract along the X-axis direction, and the sealing member 325 pushes the cover plate 503 to make the cover plate 503 cover the seal 501 in a state that the insert plate 504 is inserted into the seal 501. Specifically, the second driving element 324 selects, for example, an air cylinder, and the box sealing member 325 is located behind the second guide portion 321 of the cover folding member 308 in the initial state, and after the cover folding member 308 finishes folding the cover 503, the box sealing member 325 is driven by the second driving element 324 and pushes the cover 503 to swing further with respect to the seal 501 of the box 500. This enables the cover 503 to further reliably seal the seal 501.

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

The operation flow of the hem seal box 300 of the present embodiment will be described below. Specifically, the hem seal box 300 performs the following steps:

at S10, the first driving member 310 is driven toward the seal 501 of the cartridge 500 in the X-axis direction, and the first mounting base 311 slides linearly in the X-axis direction.

S11: the flap folder 302 is driven by the link 314 to slide linearly in the Y-axis direction, and folds the flap 502 of the flap 501 of the cassette 500.

S12: after flap hemmer 302 begins to hem flap 502, drive plate 319 begins to relax the constraint on insert plate hemmer 306, and insert plate hemmer 306 hems insert plate 504.

S13: after the flap folding member 302 finishes the folding action of the flap 502, the flap folding member 302 is driven by the link member 314 to retract from the seal 501 of the box 500;

s14: the cover folding piece 308 abuts against the cover 503 and folds the cover 503 as the first mounting base 311 slides, while the Z-axis restriction piece 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 capsule 325 against the cover plate 503 so that the cover plate 503 completely seals the closure 501.

This completes the folding of the seal 501 on one side of the box 500.
