[0043] The above scheme will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0044] Such as Figure 4 and Figure 8As shown in the figure, it is a schematic structural diagram of an embodiment of the present utility model. A special-shaped bottle arranging and grouping device is provided, which includes a bottle feeding mechanism 1, an orientation adjusting mechanism 2 and at least one grouping mechanism 3. The bottle feeding mechanism 1, the orientation adjusting mechanism 2 and the grouping mechanism 3 are respectively connected to the control system by signals. The bottle feeding mechanism 1 and the orientation adjusting mechanism 2 are installed on a frame 5, and the grouping mechanism 3 is installed on the bottle feeding mechanism 1.

[0045] Combined with Figure 5 and Figure 6 As shown in the figure, the orientation adjusting mechanism 2 is close to the feeding end of the bottle feeding mechanism 1 and is used to turn the special-shaped bottle 100 by ninety degrees. It includes a synchronous belt assembly 2-1 and a bottle mouth rubbing assembly 2-2 arranged opposite to the synchronous belt assembly 2-1. The synchronous belt assembly 2-1 and the bottle mouth rubbing assembly 2-2 are respectively arranged on both sides of the bottle feeding direction of the bottle feeding mechanism 1. The bottle mouth rubbing assembly 2-2 includes a support member 2-2a, a guiding member 2-2b arranged in the middle of the support member 2-2a and a bottle mouth rubbing member 2-2c arranged on the upper part of the support member 2-2a. The guiding member 2-2b and the bottle mouth rubbing member 2-2c are arranged in sequence along the bottle feeding direction. The bottle mouth rubbing member 2-2c and the synchronous belt assembly 2-1 clamp and rub the bottle mouth of the special-shaped bottle 100 to make the special-shaped bottle 100 rotate by ninety degrees.

[0046] As Figure 5 shown in the figure, the bottle mouth rubbing member 2-2c includes an introducing part 2-2c1, a bottle rubbing part 2-2c2 and an extracting part 2-2c3 arranged in sequence along the bottle feeding direction. Among them, the distance between the bottle rubbing part 2-2c2 and the synchronous belt assembly 2-1 is the same as the outer diameter of the bottle mouth of the special-shaped bottle 100. The distances between the introducing part 2-2c1, the extracting part 2-2c3 and the synchronous belt assembly 2-1 are greater than the outer diameter of the bottle mouth of the special-shaped bottle 100, that is, the introducing part 2-2c1 is tapered along the bottle feeding direction, and the extracting part 2-2c3 is flared along the bottle feeding direction. The length of the bottle rubbing part 2-2c2 along the bottle feeding direction is one-fourth of the circumference of the bottle mouth of the special-shaped bottle 100. When the special-shaped bottle 100 travels to the position where the introducing part 2-2c1 is connected to the bottle rubbing part 2-2c2, the bottle mouth of the special-shaped bottle 100 contacts the synchronous belt assembly 2-1 and the bottle rubbing part 2-2c2, and rotates under the drive of the synchronous belt assembly 2-1. And the length of the bottle rubbing part 2-2c2 is one-fourth of the circumference of the bottle mouth of the special-shaped bottle 100. When the special-shaped bottle 100 rotates by ninety degrees, it disengages from the bottle rubbing part 2-2c2 and is output by the extracting part 2-2c3, and the special-shaped bottle 100 stops rotating, that is, the special-shaped bottle 100 completes a ninety-degree turn.

[0047] The bottle mouth rubbing member 2-2c is made of soft materials such as silica gel and rubber, which can avoid damaging the bottle mouth of the special-shaped bottle 100, and at the same time can ensure a certain frictional force with the bottle mouth, which is convenient for the special-shaped bottle 100 to rotate and adjust the orientation.

[0048] The guiding component 2-2b includes a guiding portion and a guiding section arranged in sequence along the bottle feeding direction. The distance between the guiding portion and the synchronous belt assembly 2-1 is greater than the width of the special-shaped bottle 100, and the distance between the guiding section and the synchronous belt assembly 2-1 is consistent with the width of the special-shaped bottle 100. Thus, after passing through the guiding component 2-2b, the length direction of the body of the special-shaped bottle 100 is consistent with the bottle feeding direction, facilitating the subsequent bottle mouth rubbing component 2-2c to adjust its orientation.

[0049] As Figure 10 shown, the support member 2-2a includes a first support plate 2-2a1 fixed to the side of the bottle feeding mechanism 1 and extending in the vertical direction, a second support plate 2-2a2 connected to the first support plate 2-2a1 and extending towards the synchronous belt assembly 2-1, and a third support plate 2-2a3 connected to the second support plate 2-2a2 and extending in the vertical direction. The guiding component 2-2b is fixed to the first support plate 2-2a1, and the bottle mouth rubbing component 2-2c is fixed to the third support plate 2-2a3.

[0050] As Figure 7 shown, the synchronous belt assembly 2-1 includes a mounting frame 2-1a, a first driving wheel 2-1b, a first driven wheel 2-1c, and a tensioning wheel 2-1d rotatably mounted on the mounting frame 2-1a, a first motor 2-1c for driving the first driving wheel 2-1b to rotate, and a synchronous belt 2-1f connecting the first driving wheel 2-1b, the first driven wheel 2-1c, and the tensioning wheel 2-1d. The axes of the first driving wheel 2-1b, the first driven wheel 2-1c, and the tensioning wheel 2-1d all extend in the vertical direction. Among them, the mounting frame 2-1a is supported on the machine frame 5 via a mounting column 2-1g.

[0051] The bottle feeding mechanism 1 for conveying the special-shaped bottle 100 includes a bottle feeding track 1-1, a second driving wheel 1-2 and a second driven wheel 1-3 rotatably mounted on the bottle feeding track 1-1, a second motor 1-4 for driving the second driving wheel 1-2 to rotate, and a conveyor belt 1-5 connecting the second driving wheel 1-2 and the second driven wheel 1-3. The special-shaped bottle 100 is placed on the conveyor belt 1-5, and the second motor 1-4 drives the second driving wheel 1-3 to rotate to drive the conveyor belt 1-5 to move, thereby driving the special-shaped bottle 100 to be conveyed forward.

[0052] In order to facilitate the stable conveyance of the special-shaped bottle 100, bottle blocking components 1-6 are respectively provided on both sides of the bottle feeding track 1-1, and the special-shaped bottle 100 adjusted by the orientation mechanism 2 is conveyed forward after being limited by the two bottle blocking components 1-6.

[0053] The grouping mechanism 3 is arranged at the discharge end of the steering mechanism 2 and is used for grouping the positioned special-shaped bottles 100. It includes a counting component 3-1 and a bottle blocking assembly arranged opposite to the counting component 3-1. The counting component 3-1 and the bottle blocking assembly are respectively arranged on the bottle blocking components 1-6 on both sides of the bottle feeding mechanism 1. Preferably, the counting component 3-1 can adopt a counting sensor.

[0054] The bottle blocking assembly includes a first bottle blocking component 3-2 arranged downstream in the bottle feeding direction and a second bottle blocking component 3-3 arranged upstream in the bottle feeding direction. A grouping area is formed between the first bottle blocking component 3-2 and the second bottle blocking component 3-3. The counting component 3-1 is arranged at the inlet end of the grouping area. Preferably, the first bottle blocking component 3-2 and the second bottle blocking component 3-3 adopt air cylinders, and bottle blocking rods are arranged at the power output ends of the air cylinders. When the air cylinders act, the bottle blocking rods extend to block the advancing special-shaped bottles 100. During grouping, the first bottle blocking component 3-2 acts first to block the special-shaped bottles 100 at the position of the first bottle blocking component 3-2. When the counting component 3-2 detects that the number of the passing special-shaped bottles 100 reaches the required grouping number, the second bottle blocking component 3-3 acts to block the subsequent advancing special-shaped bottles 100, and the first bottle blocking component 3-2 retracts. The grouped special-shaped bottles 100 are close to each other and continue to be conveyed to the lower computer working area 6.

[0055] Since the bottom size of the special-shaped bottle 100 is smaller than the bottle body, in order to prevent it from tipping over, a negative pressure bottle sucking mechanism 4 is also provided, which is used to adsorb the special-shaped bottle 100 on the conveyor belt 1-5 and convey it forward, as Figure 9 、 Figure 11 and Figure 12 shown. The negative pressure bottle sucking mechanism 4 includes a negative pressure groove 4-1 arranged below the conveyor belt 1-5, a negative pressure pipe 4-2 connected to the negative pressure groove 4-1, and a negative pressure generating device connected to the negative pressure pipe 4-2. A plurality of adsorption holes 1-5a are arranged at intervals along the conveying direction on the conveyor belt 1-5. The hole pitch of the adsorption holes 1-5a on the conveyor belt 1-5 is the center distance between adjacent two bottle mouths. At the same time, a notch 4-1a corresponding to the plurality of adsorption holes 1-5a is arranged on the negative pressure groove 4-1. When the negative pressure generating device works, the negative pressure pipe 4-2 generates negative pressure, and the negative pressure groove 4-1 makes the contact surface between the conveyor belt 1-5 and the special-shaped bottle 100 maintain a negative pressure state through the notch 4-1a and the plurality of adsorption holes 1-5a, so as to stably adsorb the special-shaped bottle 100 on the conveyor belt 1-5 and prevent it from tipping over.

[0056] Among them, the negative pressure pipe 4-2 is fixed on the support column 4-3, and the support column 4-3 is supported on the frame 5. Both ends of the negative pressure groove 4-1 are respectively supported on the bottle feeding track 1-1 through the negative pressure groove support 4-4.

[0057] The working principle of the present utility model is as follows:

[0058] The irregular bottles 100 sorted by the upper bottle unscrambler are transported to the bottle feeding mechanism 1. The irregular bottles 100 are guided by the guide component 2-2b and then move between the bottle rubbing mouth component 2-2c and the synchronous belt component 2-1. When the irregular bottles 100 move to the position of the bottle rubbing part 2-2c2, as shown in FIG. Figure 5 As shown, the mouth of the special-shaped bottle 100 contacts the synchronous belt 2-1f and the bottle rubbing part 2-2c2, and the synchronous belt 2-1f drives the special-shaped bottle 100 to rotate 90 degrees to complete the adjustment and then be led out by the lead-out part 2-2c3. The adjusted special-shaped bottle 100 continues to be conveyed forward. When the special-shaped bottle 100 reaches the grouping area, the first bottle blocking component 3-2 acts to block the special-shaped bottle 100 in the grouping area. When the counting component 3-1 detects that the number of special-shaped bottles 100 arriving at the grouping area reaches the grouping requirement, the second bottle blocking component 3-3 acts to block the special-shaped bottle 100 behind from continuing to be conveyed (such as Figure 4 As shown), the first bottle blocking component 3-2 is retracted, and the grouped special-shaped bottles 100 are continuously conveyed forward to the working area 6 (e.g., the filling area) of the lower machine for filling, and this process is repeated until the grouping and filling are completed. When the length of the bottle feeding mechanism 1 is large, multiple groups of grouping mechanisms 3 can be set to improve the working efficiency of the lower machine.

[0059] In summary, the device can realize the adjustment and grouping of special-shaped bottles and improve production efficiency.

[0060] The above examples are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
