Detailed Description

The invention is further described with reference to the following figures and examples:

the first embodiment is as follows: see fig. 3-7 for an illustration:

a temporary storage device for a lid of an easy open can comprises a frame 1, wherein the frame 1 is a base frame structure, as shown in figures 3-5, the frame 1 is composed of a front frame and a rear frame, the front frame and the rear frame are identical in structure and are composed of two upright posts and a transverse connecting rod connected between the two upright posts. In practice, the frame 1 may be of other structure, and it is only a fixed mounting body of the temporary storage device for the lid body of the pop can.

As shown in fig. 3 to 7, the frame 1 defines a first vertical surface on the front side and a second vertical surface on the rear side, the first vertical surface and the second vertical surface being parallel, and as an example, the first vertical surface and the second vertical surface are perpendicular to the horizontal plane.

Referring to fig. 3-7, two sets of belt or chain mechanisms 2 are provided on the frame 1; each set of belt or chain means 2 comprises at least two belt or chain means 2, two being exemplified in the figure.

Each belt or chain mechanism 2 comprises an upper drive wheel 21, a lower drive wheel 22 and a belt or chain 23 trained around the upper drive wheel 21 and the lower drive wheel 22.

In the two groups of transmission belts or chain mechanisms 2, one group is arranged in a first vertical plane at the front side of the frame 1, the upper transmission wheels 21 of the two groups are coaxially arranged, and the lower transmission wheels 22 are also coaxially arranged; the other group is arranged in a second vertical plane at the rear side of the frame 1, and the upper driving wheels 21 and the lower driving wheels 22 of the other group are coaxially arranged.

Referring to fig. 3-7, a plurality of guide bars 3 are connected between the belts or chains 23 of the front set of belts or chain mechanisms 2, and a plurality of guide bars 3 are connected between the belts or chains 23 of the rear set of belts or chain mechanisms 2. In addition, in the space between the first vertical surface and the second vertical surface of the frame, the guide strips 3 on the front side transmission belt or chain mechanism 2 correspond to the guide strips 3 on the rear side transmission belt or chain mechanism 2 one by one in the front and rear directions, and the distance between each corresponding guide strip 3 is smaller than the diameter of the cover body 001, so that each corresponding two guide strips 3 form a track for placing the cover body.

And, referring to fig. 3-7, the two belts or chain mechanisms 2 on the front side are driven by the driving member to move synchronously, and the two belts or chain mechanisms 2 on the rear side are driven by the driving member to move synchronously, and the linear velocity of the belts or chains is the same as that of the two belts or chain mechanisms on the front side, but the moving direction is opposite, so that a plurality of tracks for placing the cover bodies are formed between the first vertical surface and the second vertical surface, and the tracks can move up and down in a reciprocating manner.

Specifically, as shown in fig. 3 to 7, each of the two sets of transmission belts or chain mechanisms 2 is identical, the upper transmission wheel 21 of the front set of transmission belts or chain mechanisms 2 is fixed on the same transmission shaft 24, and the lower transmission wheel 22 of the front set of transmission belts or chain mechanisms 2 is also fixed on the same transmission shaft 24; the upper driving wheels 21 of the rear group of driving belts or chain mechanisms 2 are fixed on the same transmission shaft 24, the lower driving wheels 22 of the rear group of driving belts or chain mechanisms 2 are also fixed on the same transmission shaft 24, and the upper driving wheels 21 of each driving belt or chain mechanism 2 are driving wheels, the ends of the transmission shafts 24 of the driving wheels are connected together at the same rotation speed ratio by a synchronous belt group 25 (see fig. 4 for details), and are connected to the same driving member, so as to achieve the effect of synchronous driving, wherein the driving member is exemplified by a servo motor 26.

Referring to fig. 6, the contact portion of the conducting bar 3 and the cover 001 is a placing surface 31 in the shape of an oblique plane or a circular arc surface, which is an example of an oblique plane in the drawing. The guide strips 3 are provided with elastic flanges 32, when the two corresponding guide strips 3 form a rail for placing the cover body, the elastic flanges 32 on the two guide strips 3 are in an upward inclined extending state, and the bottom surface of the upward inclined extending position is used as a pressing surface 321 acting on the cover body. In addition, when the elastic flange 32 is in a free state, a connecting line from the abutting surface 321 of the elastic flange 32 to the center of the cover 001 placed on the rail is smaller than the diameter of the cover 001, even if the abutting surface 321 of the elastic flange 32 abuts against the edge of the cover 001 to play a supporting role, and the cover 001 is kept in a vertical state on the rail.

Referring to fig. 7, a pressing block 33 is disposed at each end of the guide bar 3, and the pressing block 33 is hinged to the guide bar 3 by a vertical pivot 331. When the two corresponding guide bars 3 form a track for holding the cover body 001, the pressing blocks 33 on the two corresponding guide bars correspondingly form an anti-falling transition structure; in the anti-falling transition structure, the opposite surfaces of the two pressing blocks 33 are guiding inclined surfaces 332, and the end parts thereof facing the middle part of the guide bar 3 are anti-falling blocking parts 333. The elastic element 334 acts on the pressing blocks 33, the elastic force of the elastic element 334 enables the two corresponding pressing blocks 33 to have a closed natural state, in the closed natural state, the distance between the anti-falling blocking parts of the two pressing blocks 33 is smaller than the diameter of the cover body 001, and the two guide slopes 332 thereof are mutually close and gradually reduced in the cover body conveying direction along the track formed by the guide strips 3. The function of this pressing block 33 is: the two ends of the guide strip 3 play a role of blocking the cover body 001, and the cover body 001 is ensured to be overlapped into a long strip to be arranged on the track. When the long cover 001 is pushed into the track formed by the two guide bars 3, the front end of the long cover 001 touches the guiding inclined plane 332, the two pressing blocks 33 overcome the elastic force of the elastic element to open, so that the long cover 001 can smoothly enter the track formed by the two guide bars 3, and after the rear end of the long cover 001 passes through the two pressing blocks 33, the two pressing blocks 33 are reset due to the elastic force of the elastic element, and the anti-falling blocking part 333 blocks the rear end of the long cover 001.
