Figure 5 As shown, the bottle body 3 has a syringe-like structure, with an vent 31 on the bottom surface and an elastic positioning pin 21 inside the positioning cup holder 2. The elastic positioning pin 21 can use the vent 31 to position the corner of the bottle body 3, thus facilitating the control of the angle of the bottle body 3 during later assembly. Our company has applied for a patent CN221606483U for this special positioning cup holder 2. However, in previous uses, the bottle body 3 and the positioning cup holder 2 relied on manual control. That is, if the vent 31 was not aligned with the elastic positioning pin 21, the bottle body 3 would be lifted up. In this case, an operator was required to manually rotate the bottle body 3 to align the two, which increased labor costs.

[0003] Therefore, it is necessary to design an automatic alignment device to automate the above operations. Summary of the Invention

[0029] The utility model will be further explained in detail in combination with specific embodiments.

[0030] Embodiment:

[0031] As shown in Figure 1 and Figure 2 The utility model discloses an automatic bottle rolling machine 1 of cooperation positioning cup holder, including conveying unit 11, positioning unit 12, bottle rolling unit 13 and waste discharge unit 14, and conveying unit 11 passes through bottle rolling station, and positioning unit 12 is located at both sides of bottle rolling station, and bottle rolling unit 13 is located above bottle rolling station.

[0032] As shown in Figure 2 and Figure 5As shown, the conveying unit 11 includes a guide rail 111 guiding the horizontal movement of the positioning cup holder 2, a front sensor 112a sensing the arrival of the positioning cup holder 2 at the exit of the bottle rubbing station, a rear sensor 112b sensing the arrival of the positioning cup holder 2 at the entrance of the bottle rubbing station, and a front stop mechanism 113a and a rear stop mechanism 113b respectively located at the front and rear sides of the bottle rubbing station. The positioning cup holder 2 is used to position the bottle body 3, the bottom of which is provided with a vent hole 31, and the positioning cup holder 2 is provided with an elastic positioning pin 21 matching the vent hole 31.

[0033] When the bottle body 3 is placed in the positioning cup holder 2, the bottle mouth is upwardly directed, but the vent hole 31 has a high probability of not being aligned with the elastic positioning pin 21, and at this time the elastic positioning pin 21 will abut against the bottom surface of the bottle body 3, causing the bottle body 3 to be in a relatively high position. The purpose of the bottle rubbing is to rotate the bottle body 3 to an angle so that the vent hole 31 is aligned with the elastic positioning pin 21, and when the two are aligned, the elastic positioning pin 21 will automatically pass through the vent hole 31 to cause the bottle body 3 to be in a determined angle, so that the subsequent filling and assembly can be facilitated. The conveying unit 11 will cause the positioning cup holders 2 to be arranged in a row through the guide rail 111. The front sensor 112a and the rear sensor 112b will count the positioning cup holders 2 passing through the guide rail 111. In this embodiment, the automatic bottle rubbing machine 1 can rub six bottle bodies 3 at a time, so the front stop mechanism 113a and the rear stop mechanism 113b will put six positioning cup holders 2 into the bottle rubbing station to complete the bottle rubbing each time.

[0034] As shown, Figure 3 Each positioning unit 12 includes a fixed plate 121 located at the side of the bottle rubbing station and two clamping cylinders 122 provided at both ends of the fixed plate 121, each clamping cylinder 122 driving an elastic clamping block 123 used to clamp the positioning cup holder 2, the contact part of the elastic clamping block 123 with the positioning cup holder 2 matching the shape of the positioning cup holder 2, and the middle part of the fixed plate 121 being rotatably fixed at the side position of the conveying unit 11.

[0035] The positioning unit 12 precisely positions the positioning cup holder 2 entering the bottle rubbing station in a clamped manner, thereby assisting the bottle rubbing unit 13 to align each bottle mouth. The fixed plate 121 has a certain degree of rotational freedom, and when the two clamping cylinders 122 drive the respective elastic clamping blocks 123 to contact the positioning cup holder 2, the positioning cup holder 2 will exert a reaction force on the first contacting elastic clamping block 123 and cause the fixed plate 121 to rotate, so that the second contacting elastic clamping block 123 also has good contact therewith.

[0036] As shown, Figure 4As shown, the bottle-rubbing unit 13 includes multiple columns 131 located outside the bottle-rubbing station, a cylinder mounting plate 132 fixed to the top of all columns 131, a lifting cylinder 133 located below the cylinder mounting plate 132, a lifting plate 134 driven by the lifting cylinder 133, a bottle-rubbing motor 135 located on the upper part of the lifting plate 134, multiple bottle-rubbing gears 136a arranged in a single row along the conveying direction of the conveying unit 11 on the lifting plate 134, bottle-rubbing heads 137 connected to the lower part of each bottle-rubbing gear 136a, and multiple transmission gears 136b that respectively drive adjacent bottle-rubbing gears 136a. One transmission gear 136b located in the middle of the lifting plate 134 is driven by the bottle-rubbing motor 135, and the center distance between adjacent bottle-rubbing heads 137 is fixed. The lifting plate 134 is passed through by all columns 131, and the lifting plate 134 is provided with linear bearings 138 that cooperate with the columns 131.

[0037] Each bottle-rubbing head 137 corresponds to a bottle neck. Because the bottles 3 are neatly arranged in a row and spaced close together under the guidance of the positioning cup holder 2, the center distance of the bottle-rubbing heads 137 matches the conveying distance of the bottles 3. When all the bottles 11 have reached the bottle-rubbing station, the lifting cylinder 133 drives all the bottle-rubbing heads 137 to descend synchronously. The bottle-rubbing motor 135 is used to control the rotation and stopping of all the bottle-rubbing heads 137. The transmission gear 136b and the bottle-rubbing gear 136a are not necessarily equal in size or collinear in position, but all the bottle-rubbing gears 136a must rotate at the same angular velocity. The bottle-rubbing motor 135 drives the bottle-rubbing heads 137 to rotate 360°, so that when the bottles 3 and the positioning cup holder 2 are in normal condition, the elastic positioning pin 21 can definitely be inserted into the vent hole 31. After the two are positioned, the rotation of the bottles 3 stops, thus automatically rotating the bottles 3 to achieve angular positioning with the positioning cup holder 2, reducing labor costs. Linear bearing 139 allows lifting plate 134 to rise and fall with low resistance. Bottle-rubbing motor 135 can drive bottle-rubbing heads 137 one by one, but driving them through gear sets can reduce the number of bottle-rubbing motors 135 used and reduce equipment costs.

[0038] like Figure 2 As shown, each bottle-rubbing head 137 is equipped with a pressure sensor 139. The pressure sensor 139 is used to sense whether the bottle body 3 has an abnormal height after rubbing. The waste discharge unit 14 includes a waste discharge guide rail 141 located on one side of the outlet section of the guide rail 111 and a kick-out cylinder 142 located at the opposite position of the waste discharge guide rail 141. The kick-out cylinder 142 kicks out the corresponding positioning cup holder 2 according to the detection result of the pressure sensor 139.

[0039] If the bottle body 3 cannot be lowered during the rotation of the bottle rolling unit 13, the pressure sensor 139 will sense abnormal pressure, indicating that at least one of the bottle body 3 or the positioning cup holder 2 has a problem, so for this situation, when the positioning cup holder 2 reaches the front of the kicking cylinder 142, it will be pushed onto the waste removal guide rail 141 in the vertical direction of the conveying direction of the guide rail 111 for temporary storage, waiting for manual processing, without affecting the continuity of the filling and bottling work.

[0040] The working process of the automatic bottle rolling machine 1 is as follows: the front stop mechanism 113a extends into the guide rail 111 and blocks the front of the bottle rolling station, the positioning cup holder 2 carrying the bottle body 3 enters the bottle rolling station in turn, and when the rear sensor 112b counts reaches the processing capacity of the bottle rolling station (6 in the embodiment), the rear stop mechanism 113b blocks the last positioning cup holder 2; then the clamping cylinder 122 drives the elastic clamping block 123 to extend, so that the elastic clamping block 123 clamps all the positioning cup holders 2; then the lifting cylinder 133 drives all the bottle rolling heads 137 to descend, and then one by one adhere to the corresponding bottle mouth of the upper part of the bottle body 3, the bottle rolling motor 135 controls all the bottle rolling heads 137 to rotate 360° in the same direction, so that the elastic positioning needle 21 is inserted into the exhaust hole 31; during the rising of the bottle rolling head 137, the pressure sensor 139 detects whether there is a bottle body 3 that cannot completely enter the positioning cup holder 2; after the bottle rolling is completed, the positioning unit 12 releases all the positioning cup holders 2, the front stop mechanism 113a and the rear stop mechanism 113b are opened together, the positioning cup holders 2 continue to move along the guide rail 111, and when the front sensor 112 counts all the detected positioning cup holders 2, the front stop mechanism 113a and the rear stop mechanism 113b are blocked again to roll the next batch of bottle bodies 3; when the positioning cup holder 2 with a problem reaches the waste removal unit 14, the kicking cylinder 142 quickly pushes the positioning cup holder 2 with a problem onto the waste removal guide rail 141, and the remaining positioning cup holders 2 continue to move along the guide rail 111.

[0041] The above only describes some embodiments of the present application. Those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these all belong to the protection scope of the present application.
