Description

Technical Field

[0001] The invention relates to the technical field related to beverage bottle production, in particular to an automatic clamping bottle blowing machine and application thereof in beverage bottle production. Background Art

[0002] The production of beverage bottles needs to be completed by a bottle blowing machine, which is a machine that can blow plastic particles (softened into liquid) or finished bottle preforms into bottles. Specifically, the heated bottle preforms are placed in the open mold of the bottle blowing machine. After the mold is closed, compressed air is immediately introduced into the bottle preforms to inflate the bottle preforms and cling to the inner wall of the mold. The cooling water is recycled, and after the bottle preforms are inflated, they contact the mold to complete cooling. After demolding, they become beverage bottles.

[0003] During operation, after the bottle body is cooled and formed and the mold is opened, a corresponding transfer mechanism is required to transfer the formed bottle body for the convenience of subsequent processing steps. However, when some existing transfer mechanisms transfer the bottle body, the clamping arm applies a clamping force to the bottle body. In order to prevent the clamp from falling off, the clamping force needs to be large enough, which can easily cause the bottle body to deform during the transfer process. Since the bottle body has just been cooled, the shape of the bottle body is easily affected irreversibly, causing unnecessary losses. Summary of the invention

The through groove includes a spirally arranged second groove section and a first groove section and a third groove section arranged along the axial direction of the horizontal cylinder.

[0024] When the mold is opened, a support tray is arranged under the two molds. When the bottom distance between the two molds is sufficient for the support tray to rise but insufficient for the bottle body to fall, the support tray cooperates with the height adjustment mechanism to be triggered, so that the support tray is driven to rise between the two molds when the mold is opened, so as to support the formed bottle body, thereby preventing the bottle body from falling after the mold is opened, resulting in the inability of the clamping mechanism to accurately clamp the bottle mouth position of the bottle body;

[0025] Then, the clamping mechanism can clamp the bottle mouth on the supporting tray, reduce the adverse effect of the clamping force on the bottle during transportation, and reduce unnecessary losses. After the clamping mechanism clamps the bottle mouth by cooperating with the lifting mechanism, the blowing tube can be smoothly separated from the bottle.

[0026] In addition, the clamping of the bottle mouth by the clamping mechanism can be divided into two stages. In the first stage, the blow tube remains stationary, and the cylindrical spring has a certain amount of compression. The stationary blow tube can stabilize the bottle mouth, improve the fit between the clamping part and the bottle mouth, avoid slight displacement of the bottle body during the clamping process, and reduce the clamping error.

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] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0041] See also Figure 1-Figure 11 In an embodiment of the present invention, an automatic clamping type bottle blowing machine includes a frame 1 and further includes:

[0042] Two molds 2 are movably provided on the frame 1. The two molds 2 are arranged opposite to each other and are connected to a pneumatic mechanism installed on the frame 1. The pneumatic mechanism is used to drive the two molds 2 to perform mold closing and mold opening actions;

[0043] A support tray 5 is movably arranged on the frame 1, located below the two molds 2, and connected to two sets of height adjustment mechanisms respectively installed on both sides of the frame 1, the height adjustment mechanisms are connected to the sliding matching mechanisms, and the height adjustment mechanisms can drive the support tray 5 to rise between the two molds 2 when the mold is opened, so as to perform a supporting action on the formed bottle body;

[0044] A blowing pipe 22, movably disposed on the frame 1, for blowing gas into the preform, the blowing pipe 22 is connected to a lifting mechanism installed on the frame 1, and the lifting mechanism is connected to a clamping mechanism installed on the frame 1;

[0045] After the mold is opened, the clamping mechanism clamps the bottle mouth of the bottle body on the receiving tray 5 and can trigger the lifting mechanism so that the lifting mechanism drives the blowing pipe 22 to move upward and separate from the formed bottle body.

[0046] It should be noted that the air blowing pipe 22 should be connected to an external air pump so that the external air pump can blow compressed gas through the air blowing pipe 22. In addition, since the air blowing pipe 22 moves in the vertical direction during operation, the air blowing pipe 22 and the external air pump are connected via a telescopic hose.

[0047] Specifically, during operation, the robot places the preheated preform between the two molds 2, and then performs mold locking, that is, the pneumatic mechanism drives the two molds 2 to approach each other and lock them, so as to avoid the two molds 2 from opening during the blowing process;

[0048] Subsequently, compressed air is introduced through the blowing pipe 22, so that the preform is inflated and closely attached to the inner wall of the mold 2 (it should be supplemented that cooling water continuously flows into the interior of the mold 2 for cooling);

[0049] After the beverage bottle is cooled and formed, the pneumatic mechanism drives the two molds 2 to move away from each other. During this process, when the bottom spacing of the two molds 2 is greater than the diameter of the support tray 5 but smaller than the bottom diameter of the beverage, the height adjustment mechanism is triggered, and the height adjustment mechanism drives the support tray 5 to move up. Therefore, the support tray 5 rises between the two molds 2 to support the bottom of the formed beverage bottle, thereby preventing the beverage bottle from falling directly after the mold is opened, which makes it inconvenient for the clamping mechanism to clamp and transfer the bottle body;

[0050] After the mold opening process is completed, the clamping mechanism works to clamp the bottle mouth position of the bottle body. After the bottle mouth is clamped, the lifting mechanism will be triggered, and the lifting mechanism will drive the blowing tube 22 to lift up and separate from the bottle body. Finally, the clamping mechanism can transfer the bottle body from the supporting tray 5 to the bottom, and another robot will transfer it to the next processing line.

[0051] Please refer again Figure 6 The pneumatic mechanism includes a double-headed cylinder 12 installed on the frame 1, and the two movable ends of the double-headed cylinder 12 are respectively fixed with a connecting arm 13, and the two connecting arms 13 are respectively fixed to the sides of the two molds 2, and the double-headed cylinder 12 is a locking cylinder.

[0052] During the production of beverage bottles, compressed air is introduced to inflate the preform and make it close to the inner wall of the mold 2, and then the bottle body is stably formed after cooling. Therefore, the stability of the mold-closing state of the two molds 2 is highly required. It should be ensured that the two molds 2 will not open due to poor stability during the inflation of the preform, which will lead to the failure of blowing, the production of defective products, and phase loss.

[0053] In this regard, in the present application, the double-headed cylinder 12 is a clamping cylinder;

[0054] The clamping cylinder is a pneumatic component used for mold locking. It is usually used in automated production lines and robotics to achieve precise control and operation while having high safety and automated control capabilities.

[0055] Please refer again Figure 7 , Figure 8 as well as Fig. 9 The height adjustment mechanism includes a sliding fit component mounted on the frame 1 and a circumferential drive structure connected to the sliding fit component. The sliding fit component can be triggered when the mold is opened and drive the support tray 5 to move up through the circumferential drive structure to perform a support action on the bottle body located between the two molds 2. The frame 1 is provided with two first guide grooves 101, and a first slider 6 is slidably engaged in each of the two first guide grooves 101. The two first sliders 6 are respectively fixedly connected to a cross arm 8. The support tray 5 is fixed between the two cross arms 8, and the end of the cross arm 8 away from the support tray 5 is connected to the circumferential drive structure. The circumferential drive structure includes a disc 10 rotatably mounted on the side of the frame 1, and the rotation axis of the disc 10 is connected to the sliding fit component. The end of the cross arm 8 away from the support tray 5 is connected to the eccentric part of the disc 10 through a push-pull rod 11, and the two ends of the push-pull rod 11 are rotatably connected to the disc 10 and the cross arm 8.

[0056] After the beverage bottle is cooled and formed, during the mold opening process, when the bottom spacing between the two molds 2 is greater than the diameter of the supporting tray 5 but smaller than the bottom diameter of the beverage (that is, the spacing between the two molds 2 is sufficient for the supporting tray 5 to rise between the two molds 2 to support the bottom of the bottle body. At the same time, before the bottom of the bottle body is supported by the supporting tray 5, the bottle body will not fall due to the excessive bottom spacing between the two molds 2), the sliding fit assembly moves, and then the sliding fit assembly drives the disc 10 to rotate half a circle. Therefore, under the guiding action of the first guide groove 101 and the first slider 6, the disc 10 drives the cross arm 8 to rise through the push-pull rod 11, and accordingly, the supporting tray 5 rises between the two molds 2 through the spacing between the two molds 2 to support the bottom of the bottle body.

[0057] The sliding fit assembly comprises a transverse cylinder 4 rotatably mounted on the frame 1 and a transverse shaft 3 slidably fitted with the transverse cylinder 4, the transverse cylinder 4 is connected to the rotating shaft of the disc 10 via a transmission belt 9, and one end of the transverse shaft 3 located outside the transverse cylinder 4 is fixedly connected to the mold 2;

[0058] Among them, a convex column 301 is fixedly provided at one end of the horizontal axis 3 away from the mold 2, and a through groove adapted to the convex column 301 is provided on the horizontal cylinder 4. The convex column 301 passes through the through groove and is slidably connected to the horizontal cylinder 4. The through groove includes a spirally arranged second groove section 402 and a first groove section 401 and a third groove section 403 arranged along the axial direction of the horizontal cylinder 4. The two ends of the second groove section 402 are respectively connected to the first groove section 401 and the third groove section 403.

[0059] It should be added that, in conjunction with the accompanying drawings, the mold 2 is connected to multiple groups of horizontal axes 3 and horizontal cylinders 4 structures, but the boss 301 and the through groove are arranged on one of the groups for transmitting the disc 10, while the other groups can guide the movement of the mold 2 and improve the accuracy of mold closing.

[0060] During the mold opening process, the mold 2 will drive the horizontal axis 3 to slide toward the inside of the horizontal barrel 4. Accordingly, the boss 301 will pass through the first slot section 401, the second slot section 402 and the third slot section 403 in sequence. Since the first slot section 401 and the third slot section 403 are arranged along the axial direction of the horizontal barrel 4, the horizontal barrel 4 will not rotate when the boss 301 passes through the first slot section 401 and the third slot section 403. During the process of the boss 301 passing through the second slot section 402, the bottom spacing of the two molds 2 is greater than the diameter of the supporting tray 5 but smaller than the bottom diameter of the beverage. The boss 301 slides with the horizontal barrel 4 through the second slot section 402, so that the horizontal barrel 4 rotates. Then, the horizontal barrel 4 drives the disc 10 to rotate half a circle through the transmission belt 9, so that the supporting tray 5 is lifted to support the bottle body between the two molds 2, so as to prevent the bottle body from falling after the mold opening is completed, resulting in the inability of the clamping mechanism to accurately clamp the bottle mouth position of the bottle body.

[0061] Please refer again Figure 5 , Figure 6 , Fig.10 as well as Fig.11 The frame 1 is symmetrically provided with two telescopic arm groups, the telescopic arm groups include a guide arm 14 fixed to the frame 1 and a telescopic arm 15 slidably connected to the guide arm 14, and a single-head cylinder 16 is also installed on the frame 1, and the movable end of the single-head cylinder 16 is fixed to the telescopic arm 15. The clamping mechanism includes a clamping member 18 movably provided on the telescopic arm 15, the clamping member 18 is arranged in an arc shape, and is connected to an elastic component installed on the telescopic arm 15, and the elastic component is connected to the lifting mechanism.

[0062] The elastic component includes a movable block 17 movably arranged on the telescopic arm 15, two cross bars 19 slidably arranged on the movable block 17, and two cylindrical springs 20 respectively sleeved on the outer circumferences of the two cross bars 19, the clamping member 18 is fixed to the two cross bars 19, and the two ends of the cylindrical spring 20 are respectively connected to the clamping member 18 and the movable block 17, and the movable block 17 is connected to a threaded driving member installed on the telescopic arm 15.

[0063] In detail, the telescopic arm 15 is fixedly provided with a guide rail 1501, and the movable block 17 is slidably engaged with the guide rail 1501. The threaded driving member includes a driving motor 26 installed on the telescopic arm 15 and a screw rod 27 connected to the output end of the driving motor 26, and the screw rod 27 passes through the movable block 17, and the movable block 17 is threadedly connected to the screw rod 27;

[0064] The lifting mechanism includes a connecting plate 21 and a transverse block 23 slidably arranged on the frame 1, the blowing pipe 22 is fixed on the connecting plate 21, a driven plate 24 is fixed on the connecting plate 21, a sliding groove is arranged on the driven plate 24, a driving column 2301 adapted to the sliding groove is fixed on the transverse block 23, the driving column 2301 extends into the sliding groove and is slidably connected to the driven plate 24. The sliding groove includes a straight groove 2401 and an inclined groove 2402 connected to each other, and the transverse block 23 is also fixedly connected with a follower rod 25, and the follower rod 25 passes through a lug 1701 fixedly arranged on the movable block 17 and is slidably connected to the lug 1701.

[0065] Furthermore, the frame body 1 is further provided with two second guide grooves 102, in which a second slider 7 is slidably engaged respectively, and the connecting plate 21 is fixedly connected to the two second sliders 7;

[0066] After the mold is opened, the single-head cylinder 16 works to drive the telescopic arm 15 to slide toward the inside of the guide arm 14 until the clamping piece 18 reaches the side of the bottle mouth. Correspondingly, the lug 1701 slides on the follower rod 25 close to the transverse block 23. Then, the drive motor 26 works. Under the guidance of the guide rail 1501, the movable block 17 is threadedly matched with the screw rod 27, and the movable block 17 slides along the guide rail 1501. After the clamping piece 18 contacts the bottle mouth, as the movable block 17 continues to slide, the cylindrical spring 20 will be compressed. Under the elastic action of 20, the bottle body is clamped, and accordingly, the lug 1701 drives the transverse block 23 to slide on the frame body 1 through the follower rod 25, and the driving column 2301 slides in the straight groove 2401 and the inclined groove 2402 in sequence. When the driving column 2301 slides along the straight groove 2401, the driven plate 24 does not move, and when the driving column 2301 slides along the inclined groove 2402, the driving column 2301 will slide with the driven plate 24, and the driven plate 24 will drive the connecting plate 21 and the blowing pipe 22 to lift up, so that the blowing pipe 22 is separated from the bottle body;

[0067] It should be pointed out that, according to the sliding process of the driving column 2301 in the straight groove 2401 and the inclined groove 2402, the compression of the cylindrical spring 20 is divided into a first compression stage and a second compression stage. After the first compression stage, the cylindrical spring 20 has a certain amount of compression. After the second compression stage, the blowing tube 22 is separated from the bottle body. In this way, during the process of effective clamping of the bottle body, the blowing tube 22 can have a certain stabilizing effect on the bottle body, ensure the fit between the clamping member 18 and the bottle mouth, avoid slight displacement of the bottle body during the clamping process, and reduce the clamping error.

[0068] As another embodiment of the present invention, an application of the automatic clamping-type bottle blowing machine in the production of beverage bottles is also proposed.
