[0037] In this embodiment, the suction part may include: a second cylinder 150, a vacuum suction cup seat 151 and a plurality of vacuum suction cups 152. The cylinder body of the cylinder 150 is fixed on the first cylinder seat 123, and the cylinder 150 rotates synchronously with the first cylinder seat 123. The piston rod of the cylinder 150 is connected to the vacuum suction cup seat 151, and the second cylinder 150 can drive the vacuum suction cup seat 151 to move up and down or forward and backward. A plurality of vacuum suction cups 152 are arranged on the vacuum suction cup seat 151, and the vacuum suction cup 152 is used to suck the lowest packaging bag in a stack of packaging bags 108 at the initial position. In some embodiments, 4 or other numbers of vacuum suction cups 152 may be arranged on the vacuum suction cup seat 151.

[0038] According to the embodiment of the present application, when the suction part of the bag taking assembly 10 performs the bag taking action, the rotating part rotates so that the suction part is located below the storage position (such as Figure 3 As shown), at this time, the vacuum suction cup 152 is located directly below the packaging bag, and then the piston rod of the second cylinder 150 extends, the vacuum suction cup 152 approaches the bag supporting plate 102 and contacts the packaging bag 108, and the vacuum suction cup 152 absorbs the lowest packaging bag by vacuum suction, and then the piston rod of the second cylinder 150 retracts, and the vacuum suction cup 152 leaves the bag supporting plate 102. Next, the rotating part rotates and drives the suction part to rotate forward (i.e., toward the direction of the moving component) by 90 degrees, and the suction part performs the bag delivery action, the piston rod of the second cylinder 150 extends, and the vacuum suction cup 152 approaches the transverse movement component 70, and the packaging bag on the vacuum suction cup 152 contacts the transverse movement component 70, and the bag taking component 10 exchanges the packaging bag with the transverse movement component 70, so that the transverse movement component 70 obtains the packaging bag, and then the vacuum suction cup 152 releases the pressure to release the packaging bag, and the suction part completes the bag delivery action. Afterwards, the piston rod of the second cylinder 150 retracts, the rotating part rotates and drives the suction part to rotate 90 degrees upward (ie, toward the bag taking position), and the next bag taking process begins.

[0039] After the transverse moving component 70 acquires a packaging bag, it moves transversely to move the packaging bag to a first bag opening position. The first bag opening position is defined by the first bag opening component 20. In the present embodiment, the first bag opening position is located in the middle position above the first bag opening component 20.

[0040] Combined with reference Figures 5 to 7After the transverse movement assembly 70 transversely moves the packaging bag to the first bag opening position, the first bag opening assembly 20 performs the first bag opening action. The first bag opening assembly 20 may include a first clamping portion and a bag opening portion. Specifically, the first clamping portion may include a bag opening base 201. The bag opening base 201 is fixed on an operating table or an assembly line. Two parallel guide rails are fixed on the bag opening base 201, namely, a first guide rail 202 and a second guide rail 203. For simplicity, in this article, the axial extension direction of the first guide rail 202 and the second guide rail 203 is set as the left-right direction, and the direction perpendicular to the left-right direction in the plane of the bag opening base 201 is set as the front-back direction. Two sliders are respectively arranged on each guide rail, that is, a total of four sliders are included (one slider 204 is shown as an example in the figure), and the above-mentioned multiple sliders can slide left and right on the guide rails. As shown in the figure, the first slider seat 205 is fixed to the two sliders on the right side of the first guide rail 202 and the second guide rail 203, and the second slider seat 206 is fixed to the two sliders on the left side of the first guide rail 202 and the second guide rail 203.

Among them, both groups of clamps can move left and right, but only the second group of clamps (the second right clamp 212 and the second left clamp 214) can move forward and backward, while the first group of clamps (the first right clamp 211 and the first left clamp 213) cannot move forward and backward. In the embodiment of the present application, a clamp 215 is provided at the top of the first right clamp 211, a clamp 216 is provided at the top of the second right clamp 212, a clamp 217 is provided at the top of the first left clamp 213, and a clamp 218 is provided at the top of the second left clamp 214, and rubber pads (not shown in the figure) can also be provided at the top of some or all of the clamps.

[0042] In addition, guide plates 219 are respectively provided at the upper parts of the first left clamping plate 213 and the second left clamping plate 214. The two guide plates 219 define an opening toward the left side (towards the direction of the bag picking assembly 10). After the transverse movement assembly 70 obtains the packaging bag through the bag picking assembly 10, it delivers the packaging bag from between the openings defined by the two guide plates 219 to the position between the four clamps of the first bag opening assembly 20, which is the first bag opening position.

[0043] Continuing to refer to the drawings, the first clamping portion of the first bag opening assembly 20 may also include a rotating arm 221, one end of which is connected to one end of the first translation link unit 222 and the third cylinder 226, and the three are connected through an axis 229.

The other end of the first translation link unit 222 is connected to the first slider seat 205, and the other end of the second translation link unit 223 is connected to the second slider seat 206. The middle part of the rotating arm 221 has a bearing 224, and the bearing 224 is connected to the bag opening suction cup bottom plate 263 through an axis. The rotating arm 221 is generally rhombus-shaped and can rotate within a certain angle, so that the rotating arm 221 can drive the first translation link unit 222 and the second translation link unit 223 to move. Specifically, the first translation link unit 222 may include: a joint bearing 2221, a bolt 2222, a joint bearing 2223, a rotating shaft 2224, etc. Similarly, the second translation link unit 223 may include components similar to the first translation link unit 222, which will not be described in detail here.

[0044] In addition, the first clamping part may also include a buffer 227 for buffering the left-right movement of the first slider seat 205, and a buffer 228 for buffering the left-right movement of the second slider seat 206. The first translational rotation arm unit 224 and the second translational rotation arm unit 226 are driven to move by the rotating arm 221, thereby driving the first slider seat 205 and the second slider seat 206 to move left-right synchronously on the guide rail, so that the four clamping plates and the four clamping heads can move left-right synchronously. It should be noted that the synchronous left-right movement mentioned here refers to synchronous movement in the same direction or in the opposite direction, that is, when the first slider seat 205 moves to the left, the second slider seat 206 moves to the right at the same time; when the first slider seat 205 moves to the right, the second slider seat 206 moves to the left at the same time, that is, the first slider seat 205 and the second slider seat 206 move in the same direction or in the opposite direction at the same time.

[0045] In the embodiment of the present application, the second right clamping plate 212 can move forward and backward relative to the first right clamping plate 211, and the second left clamping plate 214 can move forward and backward relative to the first left clamping plate 213. The second left clamping plate 214 is described in detail below. The first clamping portion may also include an adjustment bolt (or adjustment handle) 242, and the adjustment bolt 242 passes through the second stand 241 and the second left clamping plate 214 respectively. A thin nut 243 and a compression spring 244 are provided on the adjustment bolt 242, and the thin nut 243 contacts the second stand 241, and the compression spring 244 is provided between the second stand 241 and the second left clamping plate 214. By rotating the adjustment bolt 242, the position of the second left clamping plate 214 can be fine-tuned. The first clamping portion may also include two connecting shafts connected between the second stand 241 and the first left clamping plate 213, and the two connecting shafts pass through the second left clamping plate 214, so that the second left clamping plate 214 can move between the second stand 241 and the first left clamping plate 213. The two connecting shafts have the same structure, and the following description will take one of the connecting shafts 245 as an example. The connecting shaft 245 is provided with two linear bearings 246 , and the linear bearings 246 are in close contact with the second left clamping plate 214 .

[0046] In order to drive the second left clamping plate 214 to move forward and backward between the first left clamping plate 213 and the second stand 241, the first clamping part may further include a fourth cylinder (double cylinder) 251, a roller needle seat 252, two roller needle bearings 253 and two moving limit blocks 254 ( Figure 6 Only one roller needle bearing 253 and one movable stop block 254 are shown in the figure. Among them, the fourth cylinder 251 is fixedly arranged on the bag opening base 201, and the fourth cylinder 251 is connected to the roller needle seat 252 by bolts. Two roller needle bearings 253 are respectively installed at both ends of the roller needle seat 252, and the movable stop blocks 254 are respectively close to the corresponding roller needle bearings 253, and each movable stop block 254 is respectively fixedly connected to one of the corresponding second group of clamps (that is, one movable stop block is fixedly connected to the second left clamp 214, and the other movable stop block is connected to the second right clamp 212). When moving, the fourth cylinder 251 drives the roller needle seat 252 to move, and transmits it to the movable stop block 254 through the roller needle bearing 253 on the roller needle seat 252, and then transmits it to the second left clamp 214 and the second right clamp 212, so that the second left clamp 214 and the second right clamp 212 move. Through the above embodiment, the second right clamping plate 212 and the second left clamping plate 214 can move forward and backward relative to the first right clamping plate 211 and the first left clamping plate 213, and because the four clamping plates can move left and right, the four clamps can clamp the packaging bag.

[0047] Continue to refer Figures 5 to 7The bag opening part of the first bag opening assembly 20 may include: two bottom plate supports 261 and 262, a bag opening suction cup bottom plate 263, a fifth cylinder (double cylinder) 264, two bag opening suction cup brackets 265 and 266, and suction cups 256, 257, 258, and 259. Among them, the bottom plate supports 261 and 262 are fixedly arranged on the bag opening base 201, and the bag opening suction cup bottom plate 263 is connected to the bottom plate supports 261 and 262 and is parallel to the bag opening base 201. The fifth cylinder 264 is arranged on the bag opening suction cup bottom plate 263, and two bag opening suction cup brackets 265 and 266 are respectively arranged at the front and rear ends of the fifth cylinder 264, and two vacuum suction cups are respectively arranged at the top of each bag opening suction cup bracket, for a total of four vacuum suction cups 271, 272, 273, and 274. The fifth air cylinder 264 can drive the bag opening suction cup brackets 265 and 266 to move forward and backward synchronously. The synchronous forward and backward movement here means that when the bag opening suction cup bracket 265 moves forward, the bag opening suction cup bracket 266 moves backward at the same time; when the bag opening suction cup bracket 265 moves backward, the bag opening suction cup bracket 266 moves forward at the same time, that is, the bag opening suction cup bracket 265 and the bag opening suction cup bracket 266 move synchronously towards or in the opposite direction. In this way, the four vacuum suction cups move synchronously to suck and open the packaging bag. It should be noted that the height of the four vacuum suction cups of the bag opening part can be consistent with the height of the four chucks of the first clamping part.

[0048] When the first bag opening assembly 20 is performing the bag opening action, the clamps 216 and 218 move synchronously toward the clamps 215 and 217, and the clamps clamp the packaging bag after they come into contact with each other, and the clamping position can be located on the left and right sides of the bag opening.
