[0056] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and are not limited to the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the unspecified implementation conditions are usually the conditions in conventional experiments.

[0057] See also Figures 1 to 3 , is a structural schematic diagram of an embodiment of the present invention, which provides an automatic weighing and swinging device for completing the weighing and unloading of tires after tire molding, including a weighing mechanism and a swinging and lifting mechanism.

[0058] The swing lifting mechanism includes a bracket 1, a swing slide 5 slidably connected to the bracket 1, a driving assembly 4 transmission-connected to the swing slide 5, a roller bracket 2 rotatably arranged on the swing slide 5 and a swing lever assembly 6 arranged on the bracket 1. The swing slide 5 slides up and down driven by the driving assembly 4.

[0059] In the process of the roller bracket 2 being lifted and lowered along the support 1, a weighing position, a tire receiving position and a swing position are sequentially arranged from bottom to top; at the tire receiving position, the roller bracket 2 is in a horizontal state to receive the tire blank 9 output from the molding machine side; when the swing slide 5 drives the roller bracket 2 to descend to the weighing position, the roller bracket 2 is in a horizontal state and the tire blank 9 is separated from the roller bracket 2 and placed on the weighing mechanism 3; when the swing slide 5 drives the roller bracket 2 to rise to the position of the swing lever assembly 6, the roller bracket 2 is in the swing position, and the swing lever assembly 6 blocks one end of the roller bracket 2 from rising and switches it from a horizontal state to an inclined state, and the tire blank 9 rolls away from the roller bracket 2 with its back to the molding machine side.

[0060] See also Figure 4The swing slide 5 is slidably connected to the bracket 1 via the slide rail assembly 10. Specifically, the slide rail assembly 10 includes two guide rails 10-1 fixed on the bracket 1 and two sliders 10-2 fixed on the swing slide 5. The sliders 10-2 are slidably matched with the guide rails 10-1.

[0061] Specifically, a rotating shaft 5-1 extending in the horizontal direction is provided on the swing slide 5, and a bearing seat 7 matching the rotating shaft 5-1 is installed on the roller bracket 2. During installation, the rotating shaft 5-1 is supported on the bearing seat 7, and the rotational connection between the roller bracket 2 and the swing slide 5 is realized through the cooperation of the rotating shaft 5-1 and the bearing seat 7.

[0062] See also Figure 8 The center of mass A of the roller bracket 2 deviates from the axis B of the rotating shaft 5-1 and is away from the swing lever assembly 6. When the roller bracket 2 rises to the position of the swing lever assembly 6, the swing lever assembly 6 abuts against the roller bracket 2 to block one end of it from rising, thereby causing the roller bracket 2 to tilt toward the side away from the center of mass A and swing.

[0063] In order to ensure the stability of the roller bracket 2 and facilitate resetting after swinging, an elastic support member 8 is connected between the side of the roller bracket 2 away from the swing lever assembly 6 and the swing slide 5. Correspondingly, a first connecting seat 2-6 is provided on the side of the roller bracket 2, and a second connecting seat 5-4 is provided on the swing slide 5. The two ends of the elastic support member 8 are respectively connected to the first connecting seat 2-6 and the second connecting seat 5-4. Preferably, the elastic support member 8 adopts a spring.

[0064] In order to limit the swing direction and the swing angle of the roller carriage 2, swing limit blocks 5-2 are respectively provided on the radial sides of the rotating shaft 5-1 on the swing slide 5. At the same time, two swing limit holes 2-4b matching the two swing limit blocks 5-2 are provided on the roller carriage 2. The two swing limit holes 2-4b are arranged symmetrically along the axis B of the rotating shaft 5-1. The two swing limit holes 2-4b are arranged up and down, and the swing limit hole 2-4b close to the center of mass A is located on the lower side. Preferably, the swing limit hole 2-4b is an arc-shaped waist hole. When the roller carriage 2 swings, the swing limit block 5-2 moves relatively in the corresponding swing limit hole 2-4b (such as Fig.15 and Fig.16 shown).

[0065] See also Figure 6 and Figure 7The roller carriage 2 includes a support frame 2-1, a plurality of first support rollers 2-2 horizontally rotatably arranged on the support frame 2-1, and a plurality of second support rollers 2-3 vertically rotatably arranged on the support frame 2-1, wherein the plurality of second support rollers 2-3 are located on one side of the axial direction of the plurality of first support rollers 2-2. When the roller carriage 2 swings, the tire blank 9 can roll along the plurality of first support rollers 2-2 and the plurality of second support rollers 2-3 to the next station. Preferably, the plurality of first support rollers 2-2 and the plurality of second support rollers 2-3 are evenly spaced.

[0066] See also Figure 8 A connecting plate 2-4 extending in the vertical direction is provided at the lower end of the supporting frame 2-1, and the connecting plate 2-4 is rotatably connected to the swing slide 5, that is, a bearing seat mounting hole 2-4a and two swing limit holes 2-4b are provided on the connecting plate 2-4.

[0067] In order to improve the stability of the roller bracket 2, a reinforcing rib 2-5 is connected between the support frame 2-1 and the connecting plate 2-4.

[0068] The weighing mechanism is used to complete the weighing of the tire embryo 9, including a weighing component 3-1 and a weighing bracket 3-2 arranged on the weighing component 3-1, wherein the weighing component 3-1 adopts a single electronic platform scale, and the weighing bracket 3-2 is fixed to the upper end of the weighing component 3-1. When the roller bracket 2 descends to the weighing position, the weighing bracket 3-2 can extend to the top of the roller bracket 2 to support the tire embryo 9 to complete the weighing of the tire embryo 9.

[0069] Specifically, the weighing bracket 3 - 2 includes a plurality of support bodies 3 - 2 a arranged at intervals, and the support body 3 - 2 a can extend between two adjacent first support rollers 2 - 2 .

[0070] When the roller bracket 2 descends to the weighing position, the weighing bracket 3-2 extends above the roller bracket 2. In order to prevent the tire blank 9 from rolling on the weighing bracket 3-2 and affecting the weighing, the supporting surface formed by the multiple support bodies 3-2a is a concave surface matching the tire blank 9. Specifically, the height of the multiple support bodies 3-2a gradually increases from the middle to both sides.

[0071] Combination Figure 4 and Figure 5The support 1 includes a base 1-1 and a rectangular frame 1-2 fixed on the base 1-1. The driving assembly 4 is arranged in the rectangular frame 1-2. Specifically, the driving assembly 4 includes a first cylinder 4-1 and a second cylinder 4-2 arranged from bottom to top, wherein the power output end of the first cylinder 4-1 is connected to the base 1-1, the cylinder body of the second cylinder 4-2 is connected to the cylinder body of the first cylinder 4-1, and the power output end of the second cylinder 4-2 is connected to the swing slide 5. When the first cylinder 4-1 is fully extended, the roller bracket 2 rises to the tire receiving position to receive the tire blank 9. When the first cylinder 4-1 is retracted, the roller bracket 2 descends to the weighing position, and the tire blank 9 is supported by the weighing bracket 3-2 for weighing. When the first cylinder 4-1 is fully extended and the second cylinder 4-2 is extended, the roller bracket 2 is blocked by the swing lever assembly 6 and then swings, and the tire blank 9 rolls to a lower position.

[0072] A limit plate 5-3 is provided at the upper end of the swing carriage 5, and the second cylinder 4-2 is connected to the limit plate 5-3. On the one hand, the limit plate 5-3 is used to connect with the driving assembly 4, and on the other hand, it plays a limiting role during swinging. Correspondingly, a buffer block 1-3 matching the limit plate 5-3 is provided on the rectangular frame 1-2. When the roller bracket 2 rises to a certain height, the limit plate 5-3 abuts against the buffer block 1-3 to play a buffering role.

[0073] See also Figure 4 and Figure 5 The swing lever assembly 6 includes a first rod 6-1 fixed on the rectangular frame 1-2 and extending along the conveying direction of the tire blank 9, and a second rod 6-2 arranged perpendicular to the first rod 6-1 and extending above the supporting frame 2-1, see Fig.16 When the roller bracket 2 rises to the swing position, the second rod 6-2 abuts against the support frame 2-1 to block the roller bracket 2 from rising on one side, thereby causing the roller bracket 2 to switch from a horizontal state to an inclined state and swing.

[0074] The working principle of the present invention is:

[0075] like Fig. 9 and Fig.10 As shown, when the first cylinder 4-1 is fully extended, the roller bracket 2 is located at the tire receiving position (i.e., the permanent position) to receive the tire blank 9 from the transfer ring; Fig.11 and Fig.12 As shown, when the first cylinder 4-1 is fully retracted, the roller bracket 2 descends to the weighing position, and the tire blank 9 descends to the position of the weighing mechanism 3, and the weighing is completed by the weighing mechanism 3; Fig.13 and Fig.14As shown, when the first cylinder 4-1 is fully extended and the second cylinder 4-2 is in the process of extending, one side of the roller bracket 2 is blocked by the swing lever assembly 6, and the roller bracket 2 switches from a horizontal state to an inclined state to swing, and the tire blank 9 rolls down to the next station.

[0076] In summary, the automatic weighing and swinging device has a compact structure and is suitable for automated production conveyor lines. It can realize automatic tire unloading and weighing, solve the problem of high labor intensity of manual handling, and improve production efficiency.
