[0001] The invention relates to the technical field of bottle blowing machines, and in particular to a preform inserting and unloading mechanism of a bottle blowing machine and the bottle blowing machine. Background Art

[0002] The main processes of the bottle blowing machine to form the bottle preform into a bottle are preform sorting, heating and blow molding. After the preform is heated, it is transported to the blow molding station by a robot for blowing.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the description of this embodiment, the terms "upper", "lower", "left", "right", "front", "rear" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] The present invention discloses a preform inserting and unloading mechanism for a bottle blowing machine (hereinafter referred to as the preform inserting and unloading mechanism for convenience of description), referring to Figure 1 and Figure 3As shown, the embryo insertion and unloading mechanism includes an upper cam guide rail 100 and a lower cam guide rail 200, a movable roller 300, a sliding assembly 400 and a driving member 500. The upper cam guide rail 100 is movably installed on a heating frame of the bottle blowing machine along a first direction, and is spaced apart from the lower cam guide rail 200. The upper cam guide rail 100 is provided with two cam portions 101 spaced apart along a second direction, and each cam portion 101 is provided with a descending section, a straight section and an ascending section sequentially arranged along the second direction. The lower cam rail 200 has a groove portion 201 corresponding to the cam portion 101, the movable roller 300 is movably installed between the upper cam rail 100 and the lower cam rail 200, the sliding assembly 400 is movably installed on the turntable 20 of the bottle blowing machine along the first direction, the sliding assembly 400 is connected to the movable roller 300, and is connected to the warming head 10 through the fork 600, and the driving member 500 is connected to the upper cam rail 100, and drives the upper cam rail 100 to reciprocate between the working position and the standby position. When the upper cam rail 100 is in the working position and the turntable 20 drives the sliding assembly 400 to rotate, the movable roller 300 can roll between the upper cam rail 100 and the lower cam rail 200, and the cam portion 101 can drive the movable roller 300 to move to drive the sliding assembly 400 to move along the first direction, so that the warming head 10 is inserted into or pulled out of the preform.

[0035] First of all, it should be noted that during the actual process of the bottle blowing machine, the preform transport mechanism transports the preform to a position corresponding to the preform insertion and unloading mechanism. At this time, the preform insertion and unloading mechanism drives the heating head 10 to descend, insert it into the preform and make the preform detach from the preform transport mechanism. Then, the turntable 20 drives the preform on the preform insertion and unloading mechanism to move to a position corresponding to the preform handling robot. After the preform insertion and unloading mechanism pulls the heating head 10 out of the preform, the preform handling robot can move the preform away. In the prior art, if the preform transport mechanism fails to transport the preform to the right position, or the preform handling robot and the heating head 10 are not synchronized in movement, it is very easy for the heating head 10 to hit the preform or the preform handling robot.

[0036] It can be understood that during the operation of the preform insertion and unloading mechanism of this embodiment, the driving member 500 drives the upper cam guide rail 100 to move downward in the first direction, so that the cam portion 101 protrudes from the heating frame. During the movement of the sliding assembly 400 driven by the turntable 20, the movable roller 300 moves between the upper cam guide rail 100 and the lower cam guide rail 200. When the movable roller 300 moves to the first cam portion 101, the movable roller 300 will first descend and then rise under the drive of the cam portion 101. During the downward movement of the movable roller 300, the sliding assembly 400 will descend accordingly, so that the heating head 10 descends from a high position to insert the preform, and during the upward movement of the movable roller 300, the heating head 10 will drive the preform to separate from the preform transportation mechanism. The turntable 20 continues to rotate, and when the movable roller 300 moves to the second cam portion 101, driven by the cam portion 101, the movable roller 300 first descends and then rises. During the descent of the movable roller 300, the preform is driven to be inserted into the preform handling robot. During the ascent of the movable roller 300, the heating head 10 can pull out the preform, and the handling robot can move the preform away. If during the preform insertion process, it is detected that the preform and the heating head 10 are misaligned, the driving member 500 drives the upper cam guide rail 100 to move upward in the first direction, so that the cam portion 101 is hidden inside the heating frame, and even if the turntable 20 continues to rotate, the heating head 10 will not drop, thereby avoiding the phenomenon of the heating head 10 and the preform colliding with the preform. During the preform unloading process, it is detected that the movement of the turntable 20 and the preform handling robot is not synchronized. The driving member 500 drives the upper cam guide rail 100 to move upward in the first direction, so that the cam portion 101 is hidden inside the heating frame, and even if the turntable 20 continues to rotate, the heating head 10 will not drop, thereby avoiding the phenomenon of the preform colliding with the preform handling robot. This can reduce the probability of damage to parts when a fault occurs, which is beneficial to improving the performance of the bottle blowing machine and reducing the scrap rate.

[0037] It should be noted that, since the cam structure driving the movable roller 300 is split into two parts, the upper cam guide 100 and the lower cam guide 200, the installation flexibility is strong, the tolerance for parts processing is high, and the docking adjustment is convenient. The split cam structure has good accuracy and stability, which is conducive to improving the reliability of the entire embryo insertion and removal mechanism.

[0038] It should be additionally explained that, in order to improve working efficiency, there are multiple sliding assemblies 400 , which are arranged at intervals along the circumference of the turntable 20 .

[0039] refer to Figure 2 and Figure 4As shown, the sliding assembly 400 includes a slider 410, a first slider 420 and a second slider 430. The slider 410 is connected to the roller pin 310 of the movable roller 300. The first slider 420 is arranged in the rotating disk 20 and is connected to the slider 410. One end of the first slider 420 is connected to the fork 600. The second slider 430 is arranged in parallel with the first slider 420. The second slider 430 is arranged in the rotating disk 20 and is connected to the slider 410. One end of the second slider 430 is connected to the fork 600. It can be understood that the fork 600 is connected by setting the first slider 420 and the second slider 430. The fork 600 is used to install the heating head 10. The double slider sliding structure composed of the first slider 420 and the second slider 430 has good stability and reliability, which can ensure that when the movable roller 300 moves up and down under the drive of the cam portion 101, the heating head 10 can move up and down synchronously under the drive of the sliding assembly 400.

[0040] Optionally, the first slide bar 420 is provided in the slider 410 and is locked by the connecting bolt 440, and one end of the first slide bar 420 passing through the slider 410 is connected to the shift fork 600. The second slide bar 430 is provided in the slider 410 and is locked by the fixing pin 450. It can be understood that the first slide bar 420 is connected to the slider 410 by the connecting bolt 440, and the second slide bar 430 is connected to the slider 410 by the fixing pin 450. The fixing method of the combination of the connecting bolt 440 and the fixing pin 450 can tolerate the processing error of the parts while ensuring the accuracy of the relative position of the parts. Further optionally, the second slide bar 430 is provided with a mounting groove 431, and the mounting groove 431 is used to install the retaining spring 460, and the retaining spring 460 is stopped on the slider 410. The retaining spring 460 can further improve the connection strength between the slider 410 and the second slide bar 430, and withstand the high-frequency impact force, thereby facilitating the service life of the sliding assembly 400. It should be supplemented that, in other embodiments of the present invention, the connection method of the first sliding rod 420 and the second sliding rod 430 and the slider 410 can be selected according to actual needs. For example, the first sliding rod 420 and the second sliding rod 430 and the slider 410 can be directly connected by welding, or by key connection, etc., and is not limited to the above limitations.

[0041] refer to Figure 2 and Figure 4As shown, the sliding assembly 400 further includes an elastic member 470, which is sleeved on one end of the first sliding rod 420 away from the shift fork 600, one end of the elastic member 470 is fixedly arranged with the first sliding rod 420, and the other end is stopped at the turntable 20. It can be understood that when the upper cam guide rail 100 is in the working position and the turntable 20 is rotating, the movable roller 300 moves along the surface of the upper cam guide rail 100 under the elastic force of the elastic member 470, and the tension of the elastic member 470 acts as an upward thrust of the sliding assembly 400 composed of the first sliding rod 420 and the second sliding rod 430, so that the sliding assembly 400 can move up quickly during the working process, and can even move up in a cliff-like manner, and can be suitable for the rising section curve of the upper cam guide rail 100 with a larger pressure angle, and is better suitable for high-output bottle blowing machines. In addition, according to the above, in the actual working process, the lower cam guide rail 200 always remains stationary. If the elastic member 470 breaks, the groove portion 201 on the stationary lower cam guide rail 200 can play a protective role to prevent the sliding assembly 400 from having insufficient upward thrust, which causes the fork 600 to collide with the core shaft of the heating head 10. Further optionally, the elastic member 470 is a spring. Of course, in other embodiments of the present invention, the elastic member 470 can also select other elastic structural members according to actual needs.

[0042] Optionally, the other end of the first slide bar 420 is connected to an end cap 480, one end of the elastic member 470 abuts against the end cap 480, and the other end abuts against the turntable 20. Compared with directly fixing one end of the elastic member 470 to the first slide bar 420, in this embodiment, by providing the end cap 480 on the first slide bar 420, it is possible to reduce the distortion of the elastic member 470 that may occur during the actual working process, and reduce the probability of damage to the elastic member 470. It should be supplemented that the end cap 480 can be connected to the first slide bar 420 by a connection structure such as a screw, a fixing pin, a buckle or a connection key, and the specific connection method between the first slide bar 420 and the end cap 480 is not limited here.

[0043] Optionally, a first bearing 30 is provided between the first slide bar 420 and the turntable 20, and a second bearing 40 is provided between the second slide bar 430 and the turntable 20. It is understandable that, in the actual working process, driven by the movable roller 300, the first slide bar 420 and the second slide bar 430 will move relative to the turntable 20 along the first direction, and the additional first bearing 30 and the second bearing 40 can reduce the sliding friction between the first slide bar 420 and the second slide bar 430 and the turntable 20, thereby reducing the wear of the first slide bar 420, the second slide bar 430 and the turntable 20, which is conducive to extending the working life of the first slide bar 420, the second slide bar 430 and the turntable 20. It should be supplemented that, in the embodiment of the present invention, the model and type of the first bearing 30 and the second bearing 40 can be selected according to actual needs, and the specific parameters of the first bearing 30 and the second bearing 40 are not limited here.

[0044] refer to Figure 2 and Figure 4 As shown, the embryo insertion and unloading mechanism also includes an upper guide rail 700 and a lower guide rail 800. The lower guide rail 800 is fixed on the heating frame of the bottle blowing machine. The upper guide rail 700 is connected to the lower guide rail 800 through a connecting rod 900 and is spaced apart from the lower guide rail 800. The upper cam guide rail 100 is movably mounted on the upper guide rail 700, and the lower cam guide rail 200 is fixed to the lower guide rail 800. It can be understood that by setting the upper guide rail 700 and the lower guide rail 800, the upper guide rail 700, the connecting rod 900 and the lower guide rail 800 constitute the frame of the entire embryo insertion and unloading mechanism. In the actual assembly process, the embryo insertion and unloading mechanism can be assembled into a module first, and then installed on the heating frame of the bottle blowing machine, so as to realize the modular assembly of the embryo insertion and unloading mechanism, which is beneficial to the assembly of the entire bottle blowing machine. It should be noted that, in the embodiment of the present invention, the connection mode between the lower guide rail 800 and the heating rack can be adjusted according to actual needs, and the connection mode between the lower guide rail 800 and the heating rack is not limited here. The connection mode between the lower guide rail 800 and the upper guide rail 700 and the connecting rod 900 can also be adjusted according to actual needs, and the connection mode between the lower guide rail 800 and the upper guide rail 700 and the connecting rod 900 is not limited here.

[0045] Optionally, the upper cam guide 100 includes an upper cam guide 110 for embryo insertion and an upper cam guide 120 for embryo unloading, and the upper cam guide 110 for embryo insertion and the upper cam guide 120 for embryo unloading are spaced apart along the second direction, the upper cam guide 110 for embryo insertion and the upper cam guide 120 for embryo unloading are respectively provided with a cam portion 101, and there are two driving members 500, which are respectively provided corresponding to the upper cam guide 110 for embryo insertion and the upper cam guide 120 for embryo unloading. It can be understood that, compared with setting a driving member 500, the upper cam guide 100 is split into two parts, the upper cam guide 110 for embryo insertion and the upper cam guide 120 for embryo unloading, and the upper cam guide 110 for embryo insertion and the upper cam guide 120 for embryo unloading are driven by a driving member 500 respectively, so that in the actual working process, the working positions of the upper cam guide 110 for embryo insertion and the upper cam guide 120 for embryo unloading can be adjusted separately according to the faults occurring in the embryo insertion process and the embryo unloading process, that is, if the embryo insertion process fails, but the embryo unloading process is normal, the driving member 500 drives the upper cam guide 110 for embryo insertion to move to the standby position, which will not affect the normal progress of the embryo unloading process. Conversely, if the embryo unloading process fails, but the embryo insertion process is normal, the driving member 500 drives the upper cam guide 120 for embryo unloading to move to the standby position, which will not affect the normal progress of the embryo insertion process.

[0046] It should be noted that, in the present embodiment, both driving members 500 are cylinders. Of course, in other embodiments of the present invention, both driving members 500 may be motor push rods, or one of the two driving members 500 may be a cylinder and the other a motor push rod.

[0047] Optionally, the lower cam guide 200 includes a lower cam guide 210 for inserting embryos and a lower cam guide 220 for unloading embryos, and the lower cam guide 210 for inserting embryos and the lower cam guide 220 for unloading embryos are arranged at intervals along the second direction, and the lower cam guide 210 for inserting embryos and the lower cam guide 220 for unloading embryos are respectively provided with a groove portion 201. It can be understood that when the upper cam guide 100 includes the upper cam guide 110 for inserting embryos and the upper cam guide 120 for unloading embryos, the lower cam guide 200 is also split into the lower cam guide 210 for inserting embryos and the lower cam guide 220 for unloading embryos, and they are respectively arranged corresponding to the upper cam guide 110 for inserting embryos and the upper cam guide 120 for unloading embryos, so that in the manufacturing process, it is convenient to process in pairs, that is, the upper cam guide 110 for inserting embryos and the lower cam guide 210 for inserting embryos are processed as a group of corresponding parts, and the upper cam guide 120 for unloading embryos and the lower cam guide 220 for unloading embryos are processed as a group of corresponding parts.

[0048] Of course, additional explanation is needed here. According to the foregoing, since the lower cam guide rail 200 remains stationary during the process, in an alternative embodiment of the present invention, the lower cam guide rail 200 can be an integrated structure and is not split.

[0049] The advantages of the embryo insertion and removal mechanism of this embodiment are as follows:

[0050] First, the upper cam guide rail 110 for inserting embryos and the upper cam guide rail 120 for unloading embryos are split structures, and the lower cam guide rail 210 for inserting embryos and the lower cam guide rail 220 for unloading embryos are split structures, which are more flexible, can tolerate the processing errors of parts, and are convenient for docking and adjustment of various parts;

[0051] Second: The combination of the split cam guide rail and the sliding assembly 400 can meet the accuracy and stability of the embryo insertion and unloading action under high-speed production;

[0052] Third: it avoids the collision between the heating head 10 and the preform when the preform and the heating head 10 are misaligned during the preform insertion process, and avoids the collision between the preform and the preform handling robot due to the asynchronous movement of the turntable 20 and the preform handling robot during the preform unloading process;

[0053] Fourthly, the lower guide rail 800 and the embryo insertion lower cam guide rail 210 and the embryo removal lower cam guide rail 220 do not participate in the embryo insertion and removal actions, and play a protective limit role to prevent the sliding assembly 400 from having insufficient upward thrust when the elastic member 470 breaks, thereby causing the shift fork 600 to collide with the core shaft of the heating head 10;

[0054] Fifth: The tension of the elastic member 470 acts as an upward thrust for the sliding assembly 400 composed of the first sliding bar 420 and the second sliding bar 430, so that the sliding assembly 400 can move up quickly during operation, and can even move up a cliff-like, and can be suitable for the rising curve of the upper cam guide rail 100 with a larger pressure angle, and is better suitable for high-output bottle blowing machines.

[0055] The present invention also discloses a bottle blowing machine, comprising the preform insertion and unloading mechanism of the bottle blowing machine, a turntable 20, a preform transport mechanism and a preform handling manipulator, wherein the preform insertion and unloading mechanism of the bottle blowing machine can insert the heating head 10 into the preform transported by the preform transport mechanism and make the preform detach from the preform transport mechanism, the turntable 20 can drive the preform on the preform insertion and unloading mechanism of the bottle blowing machine to move to a position corresponding to the preform handling manipulator, and after the preform insertion and unloading mechanism of the bottle blowing machine pulls the heating head 10 out of the preform, the preform handling manipulator can move the preform away. It can be understood that, due to the preform insertion and unloading mechanism described above, the phenomenon of the heating head 10 colliding with the preform when the preform and the heating head 10 are misaligned during the preform insertion process is avoided, and the phenomenon of the preform colliding with the preform handling manipulator due to the asynchronous movement of the turntable 20 and the preform handling manipulator during the preform unloading process is avoided, thereby improving the stability and reliability of the bottle blowing machine, reducing the probability of damage to parts when a fault occurs, and reducing the scrap rate.
