[0021] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.
[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a minimalist passive container clamping device includes: a pair of clamps, the two clamps are a first clamp 1 and a second clamp 2, each clamp includes a clamping side plate and a driving side plate, wherein the first clamp 1 includes a first clamping side plate 11 and a first driving side plate 12, and the second clamp 2 includes a second clamping side plate 21 and a second driving side plate 22.
[0023] Each clip has a gripping portion on its inner side for gripping the container's mouth. In this embodiment, each gripping portion is an inwardly recessed gripping groove. Specifically, the first gripping side plate 11 of the first clip 1 has a first gripping groove 111 on its inner side, and the second gripping side plate 21 of the second clip 2 has a second gripping groove 211 on its inner side.
[0024] In this embodiment, a pair of clips are stacked crosswise, wherein the first clip 1 is located at the top and the second clip 2 is located at the bottom. The front end of the first clamping side plate 11 of the first clip 1 located at the top is bent downward, and the first clamping groove 111 of the bent first clamping side plate 11 and the second clamping groove 211 of the second clamping side plate 21 of the second clip 2 can clamp the container. Figure 1 、 Figure 3 shown.
[0025] In this embodiment, the front end of the first clamping side plate 11 of the upper first clamping piece 1 is bent downward as an example. Of course, the second clamping side plate 21 of the lower second clamping piece 2 can also be bent upward so that the two clamping grooves can clamp the container.
[0026] The first clamping piece 1 and the second clamping piece 2 are intersected and stacked up and down, and the clamping pieces are directly hinged on the rotary disk 10 at the intersection position, and the clamping side plate and the driving side plate of each clamping piece are respectively located on both sides of the intersection position. Figure 5 As shown, for simplicity, Figure 5 Only one container clamping device is arranged. In this embodiment, the hinge connection structure between a pair of clips and the turntable 10 includes: a positioning stud 4, which is sequentially passed through the first clip mounting hole 101 on the first clip 1, the second clip mounting hole 201 on the second clip 2, and the support sleeve 5 located below the two clips from top to bottom, and then extends into the turntable mounting hole 1001 on the turntable 10 and is threadedly fixed thereto. A bearing is provided between each clip mounting hole and the positioning stud 4. The bearing between the first clip mounting hole 101 and the positioning stud 4 is a first bearing 6, and the bearing between the second clip mounting hole 201 and the positioning stud 4 is a second bearing 7.
[0027] To ensure reliable connection, in this embodiment, a stud retaining ring 41 is provided on the positioning stud 4, a first bearing retaining ring 61 is provided on the first bearing 6, and a second bearing retaining ring 71 is provided on the second bearing 7. The positioning stud 4 is threadedly fixed to the turntable mounting hole 1001 so that the stud retaining ring 41 is pressed against the first bearing retaining ring 61, and the second bearing retaining ring 71 is pressed against the support sleeve 5. In addition, a gasket 8 is provided on the positioning stud 4 between the first bearing 6 and the second bearing 7. The provision of the gasket 8 can reduce the installation gap and effectively reduce bearing wear.
[0028] A tension spring 3 is disposed between the drive-side plates of the pair of clips. The elastic force of the tension spring 3 causes the clamping grooves of the clamping side plates of the pair of clips to always tend to move toward each other, thereby clamping the container mouth. Specifically, the connection structure between the tension spring 3 and the drive-side plates includes: a first tension spring retaining groove 121 is disposed on the outer side of the outer end of the first drive-side plate 12, and a second tension spring retaining groove 221 is disposed on the outer side of the outer end of the second drive-side plate 22. A hook 31 is disposed at each end of the tension spring 3, and the hooks 31 at each end of the tension spring 3 are respectively hooked and retained in the first tension spring retaining groove 121 and the second tension spring retaining groove 221. The connection structure between the tension spring and the drive-side plates via the hook 31 and the retaining groove is extremely simple, facilitating the installation and replacement of the tension spring 3.
[0029] A positioning column 9 is also provided between the driving side plates of a pair of clips. The positioning column 9 is fixedly provided on the rotary disk 10. Under the action of the tension spring 3, the first driving side plate 12 and the second driving side plate 22 move closer to each other until they respectively abut on both sides of the positioning column 9, thereby making the first clamping groove 111 and the second clamping groove 211 move closer to each other to the initial state position. In the initial state, a notch 100 is provided between the outer ends of the clamping sides of the pair of clips. Figure 1 、 Figure 2 As shown in the figure. The clamping centers of the pair of clamping grooves in the initial position, the axis of the positioning column 9, and the hinge center between the clip and the base 10, that is, the axis of the positioning stud 4, are projected on a straight line in the top view. This straight line is the center line OO of the container clamping device, as shown in the figure. Figure 2 shown.
[0030] In addition, the first clamping piece 1 is provided with a container mouth guard 112 for protecting the container mouth. The container mouth guard 112 is located above the innermost end of the first clamping groove 111. The outer end of the container mouth guard 112 is an inwardly concave arc-shaped stop surface 1121 that conforms to the container mouth. The stop surface 1121 is centered relative to the centerline OO of the container clamping device. The provision of the container mouth guard 112 can protect the container mouth during the container transfer process, thereby effectively preventing the container from tilting.
[0031] The working principle is as follows: when the mouth of the container needs to enter the container clamping device, the mouth of the container squeezes the pair of driving side plates through the notch 100, so that the pair of clamping side plates move away from each other, and at the same time, the pair of driving side plates move away from each other and disengage from the positioning column 9, until the mouth of the container completely enters the first clamping groove 111 and the second clamping groove 211. Due to the provision of the container mouth ear 112, the stop surface 1121 thereon is located above the first clamping groove 111 and the second clamping groove 211. When the mouth of the container completely enters the first clamping groove 111 and the second clamping groove 211, the stop surface 1121 on the container mouth ear 112 will simultaneously block the mouth of the container, thereby adjusting the posture of the container to ensure that the container remains upright and does not tilt, which can greatly improve the accuracy of container grasping and transfer.
[0032] When the container gripping device passes the container, the container mouth is squeezed through the notch 100. During this process, the stop surface 1121 on the container mouth protection ear 112 ensures that the container remains upright during the transfer. When the container is completely released from the notch 100, the pair of clamping pieces of the container gripping device return to their original state.
[0033] The advantages of this new device are that, compared to traditional container clamping devices, it eliminates the need for a base, resulting in fewer parts, a significantly simpler structure, and extremely easy installation, effectively reducing equipment production and maintenance costs. Furthermore, the assembly contact area with the turntable is significantly reduced, significantly reducing installation gaps and effectively avoiding blind spots, thus better meeting the cleanliness requirements of filling production.
