DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-7 As shown, the present invention is a conveying buffer turntable mechanism for round bottles, comprising a turntable assembly 1 and a labeling machine 2 connected to the turntable assembly 1, wherein the turntable assembly 1 comprises:

[0041] A turntable 12, wherein the turntable 12 is used to drive the round bottles to be transported along the rotation direction of the turntable 12;

[0042] A guide assembly 13, wherein the guide assembly 13 is mounted on the turntable 12 and is used to adjust the clearance of the round bottle conveying channel;

[0043] The guide assembly 13 includes a first guide arm 131, which is rotatably mounted at the center of the turntable 12, and is used to drive the guide assembly 13 to rotate 360 ​​degrees on the turntable 12; a second guide arm 132 is slidably connected to the first guide arm 131, and the second guide arm 132 is radially telescopic along the axis on the first guide arm 131 to increase or decrease the gap in the round bottle conveying channel; a third guide arm 133 is provided at the end of the second guide arm 132;

[0044] The first guide arm 131 includes a guide arm housing 1311. A support column 155 is rotatably connected at the center of the bracket 15. The support column 155 passes through the cam 1312 and is connected to the guide arm housing 1311 through a screw. A sleeve 154 is sleeved on the outside of the support column 155. A tightening bolt fixing hole is provided on the sleeve 154. The bolt enters the tightening bolt fixing hole to fix the support column 155. The support column 155 and the outer turntable 12 are separated, so they do not rotate at the same time, and each rotates according to the needs; 360° fixed, because it is bolt-tightened and fixed, so 36 0° can be fixed at any angle and fixed in position as needed; the guide arm housing 1311 is provided with a cam 1312 fixedly mounted on the turntable 12, and the cam 1312 is fixed on the turntable 12, and the turntable 12 rotates continuously; the guide arm housing 1311 is similar to a cover, covering the cam 1312; the cam 1312 is provided with a cam groove 1314, and a follower 1315 is embedded in the cam groove 1314, and a slide rail 1313 is installed on the follower 1315, and the end of the slide rail 1313 is movably connected with the second guide arm 132;

[0045] The first guide arm 131 is rotated on the turntable 12 to reach the specified position, and then the support column 155 is fixed by bolts, and then the first guide arm 131 is fixed. Then, when the turntable 12 rotates, the cam 1312 is driven to rotate, and the cam 1312 drives the slide rail 1313 to reciprocate through the follower 1315, thereby pushing the second guide arm 132 to expand and contract radially along the axis, thereby continuously increasing or reducing the product channel gap between the guardrail and the guardrail to avoid material jamming and achieve the effect of smooth material feeding.

[0046] A first rotating block 1321 is fixedly installed at one end of the second guide arm 132, and a connecting disk 1323 is rotatably connected to the first rotating block 1321. The connecting disk 1323 is connected to the slide rail 1313, and the connecting disk 1323 and the first rotating block 1321 can be locked by a knob 1322. Both the connecting disk 1323 and the first rotating block 132 are provided with threaded holes that cooperate with the knob 1322.

[0047] Loosen the knob 1322, rotate the second guide arm 132, and then the second guide arm 132 and the third guide arm 133 are tilted, and then tighten the knob 1322 to adjust the size of the product channel gap between the guardrail and the guardrail to adapt to round bottles of different diameters.

[0048] A second rotating block 1331 is fixedly mounted on one end of the third guide arm 133 , the second rotating block 1331 is rotatably connected to the second guide arm 132 , and a return spring 1332 is obliquely arranged on the second rotating block 1331 , one end of the return spring 1332 is fixedly connected to the second guide arm 132 .

[0049] A return spring 1332 is provided between the second guide arm 132 and the third guide arm 133, which can automatically compensate for the product channel gap between the guardrail and the guardrail when the product inventory changes, thereby achieving a better guiding effect.

[0050] The guide assembly consists of three sections of guide arms to meet the guidance requirements of different product specifications and different product inventories. For example, when there are fewer products, the product channel is Fig. 9 When the output is large or the product inventory is large, the product channel is as follows: Fig.10 The width is 127mm. The second guide arm and the third guide arm are compressed inwards by the slide rail and spring, so that the product can pass smoothly even when the output is large. When the product inventory becomes smaller, it will return to the original position under the action of the slide rail and spring. Fig. 9 The turntable keeps the product in its natural state, always guiding it to the feed track to complete the transportation, while allowing the product to be buffered smoothly and steadily in the turntable.

[0051] The curvatures of the first guide arm 131 , the second guide arm 132 and the third guide arm 133 increase sequentially, and the first guide arm 131 , the second guide arm 132 and the third guide arm 133 form a crescent shape.

[0052] A guide guardrail 17 is fixedly mounted on the outer circumference of the turntable 12 , and a product channel 16 is formed between the guide guardrail 17 and the third guide arm 133 .

[0053] Example 2

[0054] Based on Example 1, see Figure 4 As shown, it also includes a driving mechanism, which is arranged at the bottom of the turntable 12 and is used to drive the turntable 12 to rotate smoothly;

[0055] The driving mechanism includes a bracket 15, a motor 151 is fixedly mounted on one side of the bracket 15, and a pinion 152 is fixedly mounted on the output shaft of the motor 151; a slewing bearing 153 is sleeved on the upper part of the sleeve 154, and the gear in the slewing bearing 153 is meshedly connected with the pinion 152, and a turntable 12 is fixedly mounted on the top of the slewing bearing 153.

[0056] In this embodiment, the motor is used to drive the slewing bearing to increase the contact area, so that the turntable runs more smoothly and the disk surface does not have any high and low jumps. The motor is connected sideways to increase the stability of the turntable operation, and the turntable with a diameter of φ500-φ1500 is universal.

[0057] See also Fig.12 As shown: When the original turntable has a larger diameter, the motor is directly connected, so the disk surface jumps and the operation is unstable. It is suitable for turntables below φ800.

[0058] Example 3

[0059] Based on Example 1, Figure 8 shown.

[0060] The turntable 12 is equipped with a feed guardrail specification assembly 14, which can be replaced according to needs, and a discharge channel 142 is formed between the feed guardrail specification assembly 14 and the turntable 12. The feed guardrail specification assembly 14 is provided with a rejection hole 141, and a rejection receiving box 18 is provided on one side of the rejection hole 141. The rejection receiving box 18 is usually designed to reject the inverted bottles on the conveying line after the turntable is fed, which will occupy the conveying station. This design adds the inverted bottle rejection to the turntable feeding track stage, so that the products after feeding are completely qualified and no inverted bottle rejection is required.

[0061] The fallen products are pushed by the products behind them and can only move in a straight line. They cannot turn with the guardrail and are pushed and squeezed down and fall into the rejection box, thus realizing the rejection of the fallen bottles.

[0062] A labeling machine 2 is installed on one side of the turntable assembly 1, and a manual feeding place 11 is provided on the turntable assembly 1. In this embodiment, the feeding platform can fully adapt to the forward and lateral directions in the figure, thereby meeting the manual feeding requirements in different directions.

[0063] See attached Figure 11-12As shown, the block has a height limit, the universality of products of different specifications is low, and different specifications also require replacement of feed guardrail specifications; it is inconvenient to change the loading position, because in the existing technology, a loading tray support assembly is required below the loading position, which can only be installed in a specific position but not in all positions. In addition, a position must be reserved in advance, and the feed position of the guardrail changes but the discharge position remains unchanged, and the guardrail must be replaced. It is not that the technology does not allow it, but the position, cost, etc. do not allow it.

[0064] The pad at the previous chassis loading position was directly welded to the main chassis, so there was no way to change the position. This time it was changed to a bolt connection that can be replaced;

[0065] In this embodiment, the stopper is removed, which increases the versatility of products of different specifications. Different specifications only require replacing the feed guardrail specification components; the feeding position can be adapted in different directions; and a function of rejecting inverted bottles is added.

[0066] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
