Description
Technical Field
[0001] The utility model relates to a clamping and transferring device, in particular to a clamping and transferring device for clamping flexible objects such as gloves. Background Art
[0002] At present, the clamping and transferring devices supporting dipping glove production lines all clamp gloves with clamping rollers and then place them on a conveyor belt for clamping and transferring.

One end of the supporting rotating shaft 30 is also provided with a drive pulley 34 on the outside of the driving pulley 35. A clamping bracket lifting drive mechanism is provided between the frame and the end plate 31. See [link / reference missing]. Figure 5 , Figure 6As shown, the lifting drive mechanism of the clamping bracket includes: an lifting drive block 52, an lifting transmission rod 54, and an lifting motor 5 mounted on the frame via a support 500. In this embodiment, the motor is mounted on the frame via a motor mounting base plate 50 through the support 500 (this is a common technique in the art and will not be described further here).

The lower end of component 1 is provided with a lower loose connecting part 5411, which is sleeved on the support shaft 53. The upper loose connecting part 5421 is movably mounted on the end plate 31 through a connecting shaft 55 passing through the upper loose connecting part 5421. Specifically, the end plate 31 is provided with a connecting seat 312, which includes a connecting base plate 3120 mounted on the end plate 31 and a pair of connecting ear plates 3121 mounted on the connecting base plate 3120. The connecting ear plates 3121 have mounting holes corresponding to the connecting shaft 55, and the two ends of the connecting shaft 55 pass through the mounting holes on the corresponding connecting ear plates 3121 (this is a conventional technique in the art and will not be described in detail here). The two rotating sliders 321 are respectively provided with a clamping rotary shaft 326 and a clamping rotary drive mechanism for driving the corresponding clamping rotary shaft 326 to rotate. Figure 1 , Figure 2 and Figure 4As shown, the specific configuration is as follows: a rotary seat 324 is provided on the rotating slider 321, and a rotary bearing 325 is provided on the clamping rotary shaft 326, with the rotary bearing 325 disposed in the rotary seat 324; the clamping rotary drive mechanism includes: a pair of rotary transmission plates 483, a rotary drive cylinder 48 movably mounted on the rotating slider 321 via the rotary drive seat 322, a rotary drive rod 482 provided on the piston rod 481 of the rotary drive cylinder 48, a rotary loop connecting part 4821 provided at the end of the rotary drive rod 482, a rotary connecting shaft movably passing through the rotary loop connecting part 4821, and both sides of the rotary connecting shaft passing through the rotary loop connecting part 4821 and movably passing through one end of the corresponding rotary transmission plate 483, with the other end of the pair of rotary transmission plates 483 locked in place. On the outer end of the clamping rotary shaft 326; on the inner end of the two clamping rotary shafts 326, clamping mounting plates 40 are provided, that is, the two ends of the clamping mounting plates 40 are respectively connected to the inner end of the corresponding clamping rotary shaft 326. Six gripper cylinders 4 are equally spaced on the clamping mounting plates 40 along a direction parallel to the axis of the support rotary shaft 30, and each gripper cylinder 4 is provided with a pair of gripping plates 41. On the frame, between the support rotary shaft 30 and the end plate 31, a guide rail 22 parallel to the axis of the support rotary shaft 30 is provided. A guide adjustment slider 24 is provided on the guide adjustment slider 22, and a guide mounting plate 26 is provided on the guide mounting plate 26. Guides 28 corresponding one-to-one with the gripper cylinders 4 are provided on the guide mounting plates 26. Figure 3 As shown, the specific structure of the guide 28 includes: an upward-opening U-shaped guide groove 280, with outwardly inclined side guide portions 281 at the edges of its two side walls and an outwardly inclined bottom guide portion 283 at the edge of its bottom wall, forming an upward-opening trumpet mouth.
[0030] In practical applications, the frame is also equipped with a low-position sensor 58, which corresponds to the lower loose sleeve connection part 5411 of the lower transmission rod 541 when it is in a low position, via a sensor bracket 57.
[0031] In actual use, the hand molds on the dipped glove production line continuously move along direction F. When the gloves on the hand molds reach the aforementioned gripping and transfer device, they are already in a semi-detached state. The six gripper cylinders 4 simultaneously grip the gloves on the corresponding hand molds. Then, the rotary drive cylinders 48 on both sides work simultaneously. The piston rods 481 of the rotary drive cylinders 48 extend forward, driving the gripping rotary shaft 326 to rotate via the rotary drive rod 482 and a pair of rotary transmission plates 483, thus pulling the gloves off the hand molds. The drive pulley 34 drives the driving pulley 35, synchronous transmission belt 37, and driven pulley 36 to rotate together. This causes the slider 321, which is locked on the synchronous transmission belt 37, to move the glove to the right along with the six gripper cylinders 4. The glove is guided to the right when it passes the guide 28, and then it is transferred to the right end. After it reaches the right end, the gripper cylinders 4 release, and the glove is put down for subsequent stacking and transfer. At this time, the lifting motor 5 works, and the lifting drive block 52 rotates, causing the lifting transmission rod 54 to move from the driving pulley 35 to the driven pulley 36. Figure 5 The low bit shown is switched to Figure 6 The high position shown raises the gripper cylinder 4. Then, the drive pulley 34 reverses, causing the gripper cylinder 4 to move to the left. During the movement, the piston rod 481 of the rotary drive cylinder 48 retracts until the gripping plate 41 of the gripper cylinder 4 faces the hand mold again, entering the next cycle. This cycle repeats continuously.
[0032] In summary, the above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent variations and modifications made to the shape, structure, features and spirit described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
