Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to a bottle pushing device for a cartoning machine. Background Art

[0002] Bottles of medicines, cosmetics, etc. need to be placed in boxes before being sealed and packaged. The traditional manual boxing mode is inefficient, labor-intensive, and has poor hygiene and safety. It is no longer suitable for modern automated production lines. The boxing machine can realize the full process automation of bottle conveying, box conveying, box loading, and box sealing. There are many ways to implement the process of putting bottles into boxes, such as dropping the bottles directly into the boxes, pushing the bottles horizontally into the boxes, and other methods. Most of the existing bottle pushing devices use a power-driven push rod to move the bottle, but the intermittent working mode of the push rod leads to slow bottle pushing speed and low efficiency, which is difficult to adapt to high-speed bottle transportation production lines. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a bottle pushing device for a cartoning machine which has a fast and stable bottle pushing speed and can cooperate with an automated cartoning production line.

[0004] The present invention is achieved through the following technical solutions:

[0005] A bottle pushing device for a cartoning machine comprises a support assembly, a power assembly, a bottle pushing guide groove assembly, a bottle pushing assembly and a chain assembly, wherein the power assembly and the bottle pushing guide groove assembly are mounted on the support assembly, and the chain assembly comprises two parallel chains, which are respectively and parallelly arranged at the left and right ends of the bottle pushing guide groove assembly and connected to the power assembly.

[0006] There are several bottle pushing assemblies, each of which includes a bottle pushing block, a push rod, a bottle pushing linear guide and a bottle pushing driven wheel. One end of the push rod is connected to the bottle pushing driven wheel, and the other end of the push rod is connected to the bottle pushing block. The push rod is arranged on the bottle pushing linear guide and can slide back and forth along the bottle pushing linear guide. Several bottle pushing linear guides are arranged horizontally and parallel on the outer surface of the bottle pushing guide groove assembly, and the two ends of the bottle pushing linear guide are respectively connected to two chains at the left and right ends of the bottle pushing assembly. The bottle pushing assembly moves circumferentially along the outer surface of the bottle pushing guide groove assembly as the chain rotates.

[0007] A bottle pushing slide and a bottle pushing guide groove are arranged on the outer surface of the bottle pushing guide groove assembly, and the bottle pushing slide and the bottle pushing guide groove are connected to each other to form an annular slideway surrounding the outer surface of the bottle pushing guide groove assembly, the bottle pushing slide groove is ringed on the front surface, the lower surface and the rear surface of the bottle pushing guide groove assembly and is parallel to the chain, the bottle pushing guide groove is arranged on the upper surface of the bottle pushing guide groove assembly, and the bottle pushing slide and the bottle pushing guide groove are located on a side close to the bottle pushing driven wheel and away from the bottle pushing block; the bottle pushing guide groove includes a planar bottle pushing V-shaped guide groove, and the V-shaped bottom of the bottle pushing V-shaped guide groove extends toward the direction of the bottle pushing block; the bottle pushing driven wheel on the bottle pushing assembly is arranged in the annular slideway surrounded by the bottle pushing slide and the bottle pushing guide groove and slides along the slideway as the chain rotates.

[0008] The above-mentioned bottle pushing process is as follows: as the chain rotates, the bottle pushing driven wheel slides along the slideway, and when it slides into the bottle pushing V-shaped guide groove on the upper surface of the bottle pushing guide groove assembly, the bottle pushing driven wheel moves along the bottle pushing V-shaped guide groove to the side of the bottle pushing block, driving the push rod to move linearly along the bottle pushing linear guide rail, and the bottle pushing block at the other end of the push rod then pushes the bottle on the conveyor line (located on the outside of the device) into the packaging box. When the bottle pushing driven wheel slides out of the bottle pushing V-shaped guide groove, the bottle pushing driven wheel drives the push rod and the bottle pushing block to return to their positions, and when the bottle pushing driven wheel returns to the bottle pushing slideway, a bottle pushing action is completed, and several bottle pushing assemblies are arranged in sequence to complete the bottle pushing action one after another, and reciprocate with the rotation of the chain, which greatly improves the speed of bottle pushing.

[0009] Furthermore, in order to reduce unnecessary bottle pushing actions, a non-bottle pushing guide groove is also provided on the upper surface of the bottle pushing guide groove assembly, and the bottle pushing guide groove and the non-bottle pushing guide groove are arranged in parallel, one end of the non-bottle pushing guide groove and one end of the bottle pushing guide groove are simultaneously connected to the bottle pushing slide groove through a bottle pushing selector, and the other end of the non-bottle pushing guide groove and the other end of the bottle pushing guide groove are simultaneously connected to the other end of the bottle pushing slide groove, and the extension direction of the non-bottle pushing guide groove does not exceed the vertical plane where the bottle pushing slide groove is located, and the bottle pushing driven wheel enters the bottle pushing guide groove or the non-bottle pushing guide groove through the selection state of the bottle pushing selector to slide to drive the bottle pushing block to push the bottle or not push the bottle. When there are bottles to be pushed at the corresponding station on the conveyor belt (located outside the device), the bottle pusher selector selects to make the bottle pusher guide groove and the bottle pusher chute unblocked, and the bottle pusher driven wheel enters the bottle pusher guide groove, driving the bottle pusher block to push the corresponding bottle; if there are no bottles or boxes at the corresponding station of the conveyor belt, and the bottle pusher block does not need to move, the bottle pusher selector selects to make the non-bottle pusher channel connected to the bottle pusher chute, and the bottle pusher driven wheel enters the non-bottle pusher guide groove, and the bottle pusher block does not move. The bottle pusher selector is controlled by the control system of the cartoning machine, and the control system senses whether there are bottles or boxes through sensors such as electric eyes.

[0010] Furthermore, in order to make the bottle more stable and more accurately oriented during the bottle pushing process, the device also includes a bottle pressing guide groove assembly and a bottle pressing assembly, the bottle pressing assembly includes a bottle pressing plate, a bottle pressing rod, a bottle pressing driven wheel, a bottle pressing linear guide rail, a bottle pressing lifting driven wheel and a bottle pressing lifting guide rail, the bottle pressing lifting guide rail is fixed on the bottle pushing linear guide rail, the bottle pressing linear guide rail can be slidably connected to the bottle pressing lifting guide rail and can move up and down along the bottle pressing lifting guide rail, the bottle pressing lifting driven wheel is arranged on the bottle pressing linear guide rail; the bottle pressing rod can be slidably connected to the bottle pressing linear guide rail and can slide left and right along the bottle pressing linear guide rail, the bottle pressing driven wheel is fixed to one end of the bottle pressing rod, the bottle pressing plate is fixed to the other end of the bottle pressing rod, and the bottle pressing plate is located directly above the bottle pushing block. The function of the bottle pressing plate is to press the bottle from above so that the bottle does not shake or slip during the bottle pushing process of the bottle pushing rod, so that the bottle is conveniently and accurately put into the box. The bottle pressing plate extends above the entire bottle pushing channel. The bottle pressing plate can also be used to push small items such as drug instructions, cosmetic instructions, and certificates of conformity. Before the bottle pushing block pushes the bottle, the instructions and the like are pushed into the box first.

[0011] The bottle pressing guide groove assembly includes a support frame and a bottle pressing path selector arranged on the support frame. The support frame surrounds the upper and lower front and rear parts of the bottle pushing guide groove assembly, and the bottle pushing assembly is located between the support frame and the bottle pushing guide groove assembly.

[0012] A bottle pressing chute, a bottle pressing guide groove, a non-bottle pressing guide groove, a bottle pressing lifting chute and a bottle pressing lifting guide groove are arranged on the inner surface of the support frame. The bottle pressing chute, the bottle pressing guide groove and the non-bottle pressing guide groove are arranged on the side close to the bottle pressing driven wheel, and their structures are similar to the above-mentioned bottle pushing chute, bottle pushing guide groove and non-bottle pushing guide groove. The difference is that the former is arranged on the inner surface and is a chute in an open groove, while the latter is arranged on the outer surface and is a chute opening outward. The bottle pressing slide surrounds the inner front surface, inner lower surface and inner rear surface of the supporting frame, and is parallel to the chain, and the bottle pressing guide groove and the non-bottle pressing guide groove are arranged on the inner upper surface of the supporting frame; one end of the bottle pressing guide groove and one end of the non-bottle pressing guide groove are connected to the bottle pressing slide through the bottle pressing selector, and the other end of the bottle pressing guide groove and the other end of the non-bottle pressing guide groove are simultaneously connected to the other end of the bottle pushing slide, and the bottle pressing guide groove or the non-bottle pressing guide groove is connected with the bottle pressing slide to form an annular slideway, and the bottle pressing driven wheel on the bottle pressing assembly is arranged in the annular slideway surrounded by the bottle pressing guide groove or the non-bottle pressing guide groove and the bottle pressing slideway and slides along the slideway with the rotation of the chain, and the bottle pressing selector is used to control the bottle pressing slideway to be connected with the bottle pressing guide groove or the non-bottle pressing guide groove, so as to control the bottle pressing driven wheel to enter the bottle pressing guide groove or the non-bottle pressing guide groove. The bottle pressing plate can be moved to press the bottle or not moved, and can be coordinated with the bottle pushing action or no bottle pushing action of the bottle pushing driven wheel, the bottle pushing slide groove and the bottle pushing guide groove.

[0013] The bottle pressing guide groove includes a planar bottle pressing V-shaped guide groove, the V-shaped bottom of which extends toward the bottle pressing plate, and the V-shaped bottom has a first straight section, which is used to enable the bottle pressing plate to move and hold the bottle for a period of time after pressing it, so as to facilitate the bottle pushing block to push the bottle smoothly; the extension direction of the non-bottle pressing guide groove does not exceed the vertical plane where the bottle pressing slide groove is located, so that the bottle pressing plate does not produce a forward pushing action when the bottle pressing driven wheel slides on it.

[0014] The bottle pressing lifting chute is a vertical chute, which is annularly arranged on the side of the support frame close to the bottle pressing lifting driven wheel and parallel to the chain. The bottle pressing lifting driven wheel is arranged in the bottle pressing lifting chute and slides along the bottle pressing lifting chute in a vertical plane. The bottle pressing lifting chute is provided with a bottle pressing lifting guide groove at the part above the bottle pushing guide groove assembly. The bottle pressing lifting guide groove includes a descending section, a second straight section and an ascending section in sequence. The second straight section on the bottle pressing lifting guide groove is opposite to the first straight section on the bottle pressing V-shaped guide groove. When the bottle pressing driven wheel reaches the first straight section of the bottle pressing V-shaped guide groove to drive the bottle pressing plate to the top of the bottle to be pushed, the bottle pressing lifting driven wheel passes through the descending section of the bottle pressing lifting guide groove and reaches the second straight section. Due to the decrease in the height of the second straight section, the bottle pressing lifting driven wheel descends to drive the bottle pressing plate to descend and press on the bottle to be pushed. When the bottle is pushed by the bottle pushing block, the bottle pressing driven wheel slides out of the bottle pressing V-shaped guide groove, and the bottle pressing lifting driven wheel rises through the rising section, and the bottle pressing plate exits the bottle pushing channel and rises and lifts up at the same time. The bottle pressing driven wheel pushes the bottle pressing plate to the top of the bottle, and the bottle pressing lifting driven wheel pushes the bottle pressing plate down to press on the bottle. The bottle pressing driven wheel and the bottle pressing lifting driven wheel cooperate to complete a bottle pressing action.

[0015] Furthermore, the starting position of the V-shaped bottom of the bottle pressing V-shaped guide groove is located at the front end of the running direction compared to the V-shaped bottom of the bottle pushing V-shaped guide groove, so that the bottle pressing plate reaches the pushing position before the bottle pushing block; the first straight section of the V-shaped bottom of the bottle pressing V-shaped guide groove and the second straight section of the bottle pressing lifting guide groove on the bottle pressing lifting slide are opposite and have the same length, which is equal to the product of the circumferential running speed of the bottle pressing assembly and the bottle pressing residence time of the bottle pressing plate. In this way, the bottle pressing plate reaches the pushing position and descends to press on the bottle, and stays for a certain time to facilitate the bottle pushing block to complete the bottle pushing action. After the bottle pushing is completed, the bottle pressing plate rises and returns to its position.

[0016] The working process of the above-mentioned bottle pushing device is as follows: the power component drives the sprocket to rotate, and the chain connected to the sprocket runs around the left and right sides of the bottle pushing guide groove component, driving the bottle pushing component to run along the surface of the bottle pressing guide groove component. When the bottle pushing action is required, the bottle pushing path selector connects the bottle pushing guide groove with the bottle pushing slide groove, and the bottle pressing path selector connects the bottle pressing guide groove with the bottle pressing slide groove. The bottle pressing driven wheel first enters the bottle pressing guide groove, drives the bottle pressing plate to move to the bottle pushing position, and the bottle pressing lifting driven wheel enters the bottle pressing lifting guide groove at the same time, drives the bottle pressing plate to descend and press on the bottle, and the bottle pushing driven wheel enters the bottle pushing guide groove, drives the bottle pushing block to move to the bottle pushing position for pushing the bottle. After the bottle pushing is completed, the bottle pushing driven wheel slides out of the bottle pushing guide groove, the bottle pressing driven wheel slides out of the bottle pressing guide groove, the bottle pressing lifting driven wheel slides out of the bottle pressing lifting guide groove at the same time, and the bottle pressing plate rises The bottle pushing block and the bottle pressing plate have no bottle pushing and bottle pressing actions, until the bottle pushing driven wheel slides out of the non-bottle pushing guide groove, and the bottle pressing driven wheel slides out of the non-bottle pressing guide groove; in this way, the bottle pushing driven wheel, the bottle pressing driven wheel, and the bottle pressing lifting driven wheel on each bottle pressing assembly are arranged and slid in sequence on the bottle pushing guide groove assembly and the bottle pressing guide groove assembly, and enter the bottle pushing guide groove, the bottle pressing guide groove, and the bottle pressing lifting guide groove, so as to cooperate to complete the continuous bottle pushing process.

[0017] Further, in order to adapt to bottles of different heights, the support frame of the bottle pressing guide groove assembly is a height-adjustable structure. The difference in bottle height will cause the distance between the bottle pushing block and the bottle pressing plate to change. In particular, when the change is large, it is necessary to adjust the distance between the bottle pushing guide groove assembly and the bottle pressing guide groove assembly. The support frame includes a lower support frame, an upper support frame and a height servo adjustment assembly. The lower support frame and the upper support frame are connected by two groups of the height servo adjustment assemblies located on the front side and the rear side, respectively. The bottle pressing lifting chute and the bottle pressing chute at the connection are smoothly transitioned. The height servo adjustment assembly includes a first servo motor assembly, a screw rod and a transmission nut assembly. The first servo motor assembly is connected to the screw rod to drive the screw rod to rotate. The transmission nut assembly is screwed on the screw rod. The transmission nut assembly is fixedly connected to the upper support frame. The rotation of the screw rod drives the upper support frame to rise and fall relative to the lower support frame to adjust the distance between the upper support frame and the bottle pushing guide groove assembly, and then adjust the distance between the bottle pushing guide groove and the bottle pressing guide groove, and between the non-pushing bottle guide groove and the non-pressing bottle guide groove, so as to adapt to bottles of different heights.

[0018] Furthermore, a bottle pressing protection rod is provided on the bottle pressing V-shaped guide groove, and the bottle pressing protection rod is arranged at the V-shaped turning point of the bottle pressing V-shaped guide groove and becomes the inner side of the guide groove there. The connection between the bottle pressing protection rod and the bottle pressing V-shaped guide groove has a certain elasticity, and the protection rod is connected to the bottle pressing overload protection cylinder. When the bottle pressing driven wheel gets stuck, jammed, etc. at the V-shaped turning point of the bottle pressing V-shaped guide groove, resulting in increased resistance, the resistance is transmitted to the bottle pressing overload protection cylinder through the bottle pressing protection rod to trigger a system alarm or automatic shutdown.

[0019] Furthermore, a bottle pushing protection rod is provided on the bottle pushing V-shaped guide groove, and the bottle pushing protection rod is arranged at the V-shaped turning point of the bottle pushing V-shaped guide groove and becomes the inner side of the guide groove there. The connection between the bottle pushing protection rod and the bottle pushing V-shaped guide groove has a certain elasticity, and the bottle pushing protection rod is connected to the bottle pushing overload protection cylinder. When the bottle pushing driven wheel is stuck or jammed at the V-shaped turning point of the bottle pushing V-shaped guide groove, resulting in increased resistance, the resistance is transmitted to the bottle pushing overload protection cylinder through the bottle pushing protection rod to trigger a system alarm or automatic shutdown.

[0020] Furthermore, two chain guide grooves are relatively arranged on the left and right sides of the bottle pushing guide groove assembly, and chain guide wheels are respectively installed at both ends of the bottle pushing linear guide rail on each bottle pushing assembly. The chain guide wheels are arranged in the chain guide grooves and slide along the chain guide grooves. The two ends of the bottle pushing linear guide rail are respectively connected to the two chains at the same time. The rotation of the chain drives the bottle pushing linear guide rail to move, and it rotates smoothly along the direction of the chain guide groove under the action of the chain guide wheels.

[0021] Furthermore, the push bottle selector and the pressure bottle selector have the same structure, both including a selector plate and a selector cylinder, the selector plate can be rotatably arranged at the connection between the push bottle guide groove, the non-push bottle guide groove and the push bottle slide groove, or at the connection between the pressure bottle guide groove, the non-pressure bottle guide groove and the pressure bottle slide groove, the selector cylinder is connected to the selector plate, and drives the selector plate to rotate to connect different channels. The selector can also adopt any existing structure that can realize the selector function.

[0022] Furthermore, the power assembly includes a second servo motor assembly, a driving sprocket assembly and a driven sprocket assembly, the driving sprocket assembly includes a driving shaft and two driving sprockets connected at both ends of the driving shaft, the driven sprocket assembly includes a driven shaft and two driven sprockets connected at both ends of the driven shaft, the driving sprocket assembly and the driven sprocket assembly are arranged parallel to and opposite to each other on the bracket assembly, the second servo motor assembly is connected to the driving shaft on the driving sprocket assembly to drive the two driving sprockets to rotate, and the two chains pass around the driving sprocket and the driven sprocket respectively.

[0023] It should be noted that the device of the present invention, in addition to being used as a mechanism in a cartoning machine for pushing bottles, can also be used for pushing functions in other fields, such as pushing boxes and bags, and the shape and size of the bottle pushing block and the bottle pressing block can be designed according to the specific category of the pushed items. The pushing functions realized by applying the structure of the present invention are applied to other fields and still fall within the scope of protection of the present invention.

[0024] The invention drives the bottle pushing assembly to and fro by a chain, and the bottle pushing assembly can be arranged in multiple groups according to actual conditions. The multiple groups of bottle pushing assemblies can continuously reciprocate to push the bottle, so that the bottle pushing action is realized continuously, the bottle pushing speed is improved, the production efficiency is improved, and the production requirements of the high-speed conveyor line are adapted. The bottle pushing assembly cooperates with the bottle pushing guide groove assembly, and the bottle pushing function is realized by a cam structure, so that the bottle pushing action is stable and the power consumption is low. By setting the no-bottle-pushing function, the bottle pushing action is reduced and the efficiency is high. At the same time, a bottle pressing assembly is arranged, and the bottle pressing assembly is realized by a cam structure. When pushing the bottle, the bottle is first pressed, and the bottle does not produce displacement in other directions and does not shake, so that the bottle can be accurately positioned during the pushing process, and the success rate of the bottle pushing is improved.

One end of the push rod 512 is connected to the bottle pushing driven wheel 513, and the other end of the push rod 512 is connected to the bottle pushing block 511. The push rod 512 is arranged on the bottle pushing linear guide 514 and can slide back and forth along the bottle pushing linear guide 514; a plurality of the bottle pushing linear guides 514 are arranged horizontally and parallel on the outer surface of the bottle pushing guide groove assembly 3, and the two ends of the bottle pushing linear guide 514 are respectively connected to the two chains at the left and right ends of the bottle pushing assembly 51.

[0044] like Figure 6The bottle pressing assembly 52 includes a bottle pressing plate 521, a bottle pressing rod 522, a bottle pressing driven wheel 523, a bottle pressing linear guide 524, a bottle pressing lifting driven wheel 525 and a bottle pressing lifting guide 526. The bottle pressing lifting guide 526 is fixed to the bottle pushing linear guide 514. The bottle pressing linear guide 524 is slidably connected to the bottle pressing lifting guide 526 and can move up and down along the bottle pressing lifting guide 526. The bottle pressing lifting driven wheel 525 is arranged on the bottle pressing linear guide 524; the bottle pressing rod 522 is slidably connected to the bottle pressing linear guide 524 and can slide left and right along the bottle pressing linear guide 524. The bottle pressing driven wheel 523 is fixed to one end of the bottle pressing rod 522, the bottle pressing plate 521 is fixed to the other end of the bottle pressing rod 522, and the bottle pressing plate 521 is located directly above the bottle pushing block 511. The function of the bottle pressing plate 521 is to press the bottle from above so that the bottle does not shake or slip when the bottle pushing rod pushes the bottle, so that the bottle can be put into the box accurately. The bottle pressing plate 521 extends above the entire bottle pushing channel. The bottle pressing plate 521 can also be used to push small items such as drug instructions, cosmetic instructions, and certificates of conformity. Before the bottle pushing block 511 pushes the bottle, the instructions are pushed into the box first.

[0045] like Figure 8 , Fig. 9 A bottle pushing chute 31, a bottle pushing guide groove 32 and a non-bottle pushing guide groove 33 are arranged on the outer surface of the bottle pushing guide groove assembly 3. The bottle pushing guide groove 32 and the non-bottle pushing guide groove 33 are arranged in parallel. One end of the non-bottle pushing guide groove 33 and one end of the bottle pushing guide groove 32 are simultaneously connected to the bottle pushing chute 31 through a bottle pushing path selector. The other end of the non-bottle pushing guide groove 33 and the other end of the bottle pushing guide groove 32 are simultaneously connected to the other end of the bottle pushing chute 31. The bottle pushing guide groove 32 or the non-bottle pushing guide groove 33 and the bottle pushing chute 31 are connected to each other to form an annular slideway surrounding the outer surface of the bottle pushing guide groove assembly 3. The bottle pushing chute 31 The bottle pushing guide groove 32 and the non-bottle pushing guide groove 33 are arranged on the upper surface of the bottle pushing guide groove assembly 3, and the bottle pushing slide groove 31, the bottle pushing guide groove 32 and the non-bottle pushing guide groove 33 are located on a side close to the bottle pushing driven wheel 513 and away from the bottle pushing block 511; the bottle pushing guide groove 32 includes a planar bottle pushing V-shaped guide groove, and the V-shaped bottom of the bottle pushing V-shaped guide groove extends toward the direction of the bottle pushing block 511; the extension direction of the non-bottle pushing guide groove 33 does not exceed the vertical plane where the bottle pushing slide groove 31 is located. The bottle pushing driven wheel 513 is arranged in the annular slideway formed by the bottle pushing guide groove 32 or the non-bottle pushing guide groove 33 and the bottle pushing slide groove 31 and slides along the slideway as the chain rotates, and enters the bottle pushing guide groove 32 or the non-bottle pushing guide groove 33 to slide through the selection state of the bottle pushing selector to drive the bottle pushing block 511 to push the bottle or not push the bottle. The non-bottle pushing guide groove 33 is provided for reducing unnecessary bottle pushing actions.

[0046] The process of pushing or not pushing the bottle is as follows: when there is a bottle to be pushed at the corresponding station on the conveyor belt (located outside the device), the bottle pushing path selector selects to make the bottle pushing guide groove 32 and the bottle pushing slide groove 31 unblocked, and as the chain rotates, the bottle pushing driven wheel 513 slides along the slideway, and when it slides into the bottle pushing V-shaped guide groove on the upper surface of the bottle pushing guide groove assembly 3, the bottle pushing driven wheel 513 moves toward the bottle pushing block 511 along the bottle pushing V-shaped guide groove, driving the push rod 512 to move linearly along the bottle pushing linear guide rail 514, and the bottle pushing block 511 at the other end of the push rod 512 pushes the bottle on the conveyor line (located outside the device) into the packaging box; the bottle pushing driven wheel 5 In the process of sliding out of the bottle pushing V-shaped guide groove, the bottle pushing driven wheel 513 drives the push rod 512 and the bottle pushing block 511 to return to their positions. When the bottle pushing driven wheel 513 returns to the bottle pushing chute 31, the bottle pushing block 511 returns to its position, completing a bottle pushing action; if there is no bottle or box on the corresponding station of the conveyor belt, the bottle pushing block 511 does not need to move, then the bottle pushing path selector selects to connect the non-bottle pushing channel with the bottle pushing chute 31, and the bottle pushing driven wheel 513 enters the non-bottle pushing guide groove 33, and the bottle pushing block 511 does not move; a plurality of bottle pushing assemblies 51 are arranged in sequence to complete the bottle pushing action or no action, and reciprocate with the rotation of the chain, which greatly improves the speed of bottle pushing. The bottle pushing path selector is controlled by the control system of the cartoning machine, and the control system senses whether there is a bottle through a sensor device such as an electric eye.

[0047] like Figures 10 to 12 The bottle pressing guide groove assembly 4 includes a support frame 41 and a bottle pressing selector arranged on the support frame 41. The support frame 41 surrounds the upper and lower front and rear parts of the bottle pushing guide groove assembly 3. The bottle pushing assembly 51 is located between the support frame 41 and the bottle pushing guide groove assembly 3.

[0048] like Fig.10 , Fig.11The inner surface of the support frame 41 is provided with a bottle pressing chute 49, a bottle pressing guide groove 42, a non-bottle pressing guide groove 43, a bottle pressing lifting chute 48 and a bottle pressing lifting guide groove 410. The bottle pressing chute 49, the bottle pressing guide groove 42 and the non-bottle pressing guide groove 43 are arranged on the side close to the bottle pressing driven wheel 523, which are similar to the above-mentioned bottle pushing chute 31, the bottle pushing guide groove 32 and the non-bottle pushing guide groove 33. The difference is that the former is arranged on the inner surface and is a chute in the open groove, and the latter is arranged on the outer surface and is a chute opening outward. The bottle pressing chute 49 surrounds the inner front surface, the inner lower surface and the inner rear surface of the support frame 41 and is parallel to the chain. The bottle pressing guide groove 42 and the non-bottle pressing guide groove 43 are arranged on the inner upper surface of the support frame 41; one end of the bottle pressing guide groove 42 and one end of the non-bottle pressing guide groove 43 are connected to the bottle pressing chute 49 through the bottle pressing selector, and the other end of the bottle pressing guide groove 42 and the other end of the non-bottle pressing guide groove 43 are simultaneously connected to the other end of the bottle pushing chute 31. The bottle pressing guide groove 42 or the non-bottle pressing guide groove 43 is connected with the bottle pressing chute 49 to form an annular slideway, and the bottle pressing driven wheel 523 on the bottle pressing assembly 52 is arranged in the annular slideway surrounded by the bottle pressing guide groove 42 or the non-bottle pressing guide groove 43 and the bottle pressing chute 49 and slides along the slideway with the rotation of the chain, and the bottle pressing path selector is used to control the bottle pressing chute 49 to communicate with the bottle pressing guide groove 42 or the non-bottle pressing guide groove 43, so as to control the bottle pressing driven wheel 523 to enter the bottle pressing guide groove 42 or the non-bottle pressing guide groove 43. Further, the bottle pressing plate 521 is moved to press the bottle or not to move, and the bottle pushing action or no bottle pushing action of the bottle pushing driven wheel 513, the bottle pushing chute 31 and the bottle pushing guide groove 32 are coordinated simultaneously.

[0049] like Fig.11 , Fig.13 The bottle pressing guide groove 42 includes a planar bottle pressing V-shaped guide groove, the V-shaped bottom of which extends toward the bottle pressing plate 521, and the V-shaped bottom has a first straight section 421, which is used to enable the bottle pressing plate 521 to move and hold the bottle for a period of time after pressing it, so as to facilitate the bottle pushing block 511 to push the bottle smoothly; the extension direction of the non-bottle pressing guide groove 43 does not exceed the vertical plane where the bottle pressing slide groove 49 is located, so that the bottle pressing plate 521 does not produce a forward pushing action when the bottle pressing driven wheel 523 slides thereon.

[0050] like Figure 4 , Fig.11 , Fig.14 The bottle pressing lifting chute 48 is a vertical chute, which is annularly arranged on the side of the support frame 41 close to the bottle pressing lifting driven wheel 525 and parallel to the chain. The bottle pressing lifting driven wheel 525 is arranged in the bottle pressing lifting chute 48 and slides in a vertical plane along the bottle pressing lifting chute 48. The bottle pressing lifting chute 48 is provided with a bottle pressing lifting guide groove 410 at the part above the bottle pushing guide groove assembly 3. Fig.14The bottle pressing lifting guide groove 410 includes a descending section 4101, a second straight section 4102 and an ascending section 4103 in sequence. The second straight section 4102 on the bottle pressing lifting guide groove 410 is opposite to the first straight section 421 on the bottle pressing V-shaped guide groove.

[0051] When the bottle pressing driven wheel 523 reaches the first straight section 421 of the bottle pressing V-shaped guide groove and drives the bottle pressing plate 521 to reach the top of the bottle to be pushed, the bottle pressing lifting driven wheel 525 passes through the descending section 4101 of the bottle pressing lifting guide groove 410 and reaches the second straight section 4102. Due to the decrease in the height of the second straight section 4102, the bottle pressing lifting driven wheel 525 descends and drives the bottle pressing plate 521 to descend and press on the bottle to be pushed. After the bottle is pushed by the bottle pushing block 511, the bottle pressing driven wheel 523 slides out of the bottle pressing V-shaped guide groove, and the bottle pressing lifting driven wheel 525 ascends through the ascending section 4103, and the bottle pressing plate 521 exits the bottle pushing channel and rises and lifts. The bottle pressing driven wheel 523 pushes the bottle pressing plate 521 to reach the top of the bottle, and the bottle pressing lifting driven wheel 525 pushes the bottle pressing plate 521 to descend and press on the bottle. The bottle pressing driven wheel 523 and the bottle pressing lifting driven wheel 525 cooperate to complete a bottle pressing action. The functions of the bottle pressing guide groove assembly 4 and the bottle pressing assembly 52 are to make the bottle more stable and more accurately oriented during the bottle pushing process.

[0052] The starting position of the V-shaped bottom of the bottle pressing V-shaped guide groove is located at the front end of the running direction compared to the V-shaped bottom of the bottle pushing V-shaped guide groove, so that the bottle pressing plate 521 reaches the pushing position before the bottle pushing block 511. Figure 4 , Fig.11 The first straight section 421 of the V-shaped bottom of the bottle pressing V-shaped guide groove and the second straight section 4102 of the bottle pressing lifting guide groove 410 on the bottle pressing lifting slide are opposite and have the same length, which is equal to the product of the circumferential running speed of the bottle pressing assembly 52 and the bottle pressing residence time of the bottle pressing plate 521. In this way, the bottle pressing plate 521 reaches the pushing position and simultaneously descends to press on the bottle, and stays for a certain time to facilitate the bottle pushing block 511 to complete the bottle pushing action. After the bottle pushing is completed, the bottle pressing plate 521 rises and returns to its original position.

[0053] In order to adapt to bottles of different heights, the support frame 41 of the bottle pressing guide groove assembly 4 is a height-adjustable structure. The difference in bottle height will cause the distance between the bottle pushing block 511 and the bottle pressing plate 521 to change. In particular, when the change is large, it is necessary to adjust the distance between the bottle pushing guide groove assembly 3 and the bottle pressing guide groove assembly 4. Fig.10 , Fig.11The support frame 41 includes a lower support frame 412, an upper support frame 411 and a height servo adjustment component 413. The lower support frame 412 and the upper support frame 411 are connected by two groups of the height servo adjustment components 413 located on the front side and the rear side respectively. The bottle pressing lifting chute 48 and the bottle pressing chute 49 at the connection are smoothly transitioned. The height servo adjustment component 413 includes a first servo motor component 4131, a screw rod 4133 and a transmission nut component 4132. The first servo motor component 4131 is connected to the The screw rod 4133 is connected to drive the screw rod 4133 to rotate, and the transmission nut assembly 4132 is screwed on the screw rod 4133. The transmission nut assembly 4132 is fixedly connected to the upper support frame 411. The rotation of the screw rod 4133 drives the upper support frame 411 to rise and fall relative to the lower support frame 412 to adjust the distance between the upper support frame 411 and the bottle pushing guide groove assembly 3, and then adjust the distance between the bottle pushing guide groove 32 and the bottle pressing guide groove 42, and the non-bottle pushing guide groove 33 and the non-bottle pressing guide groove 43 to adapt to bottles of different heights.

[0054] like Figure 8 , Fig. 9 The bottle pressing V-shaped guide groove is provided with a bottle pressing protection rod 44, which is arranged at the V-shaped turning point of the bottle pressing V-shaped guide groove and becomes the inner side of the guide groove there. The connection between the bottle pressing protection rod 44 and the bottle pressing V-shaped guide groove has a certain elasticity (such as Figure 8 , Fig. 9 As shown in the figure, one end is used as a fulcrum and the other end can rotate elastically), the protection rod is connected to the bottle pressing overload protection cylinder 45. When the bottle pressing driven wheel 523 is stuck or jammed at the V-shaped turning part of the bottle pressing V-shaped guide groove, resulting in increased resistance, the resistance is transmitted to the bottle pressing overload protection cylinder 45 through the bottle pressing protection rod 44 to trigger a system alarm or automatic shutdown.

[0055] Similar to the V-shaped guide groove for pressing bottles, Fig.11 , Fig.13 The push bottle V-shaped guide groove is provided with a push bottle protection rod 34, which is arranged at the V-shaped turning point of the push bottle V-shaped guide groove and becomes the inner side of the guide groove there. The connection between the push bottle protection rod 34 and the push bottle V-shaped guide groove has a certain elasticity (such as Fig.11 , Fig.13 As shown in the figure, one end is used as a fulcrum and the other end can rotate elastically), the bottle pushing protection rod 34 is connected to the bottle pushing overload protection cylinder 35. When the bottle pushing driven wheel 513 is stuck or jammed at the V-shaped turning part of the bottle pushing V-shaped guide groove, resulting in increased resistance, the resistance is transmitted to the bottle pushing overload protection cylinder 35 through the bottle pushing protection rod 34 to cause a system alarm or automatic shutdown.

[0056] like Figure 8 , Fig. 9 , Fig.11 , Fig.13 The pushing bottle selector and the pressing bottle selector have the same structure, both of which include a selector plate and a selector cylinder, which are respectively a pushing bottle selector plate 36 and a pushing bottle selector cylinder 37, and a pressing bottle selector plate 46 and a pressing bottle selector cylinder 47. The selector plate can be rotatably arranged at the connection between the pushing bottle guide groove 32, the non-pushing bottle guide groove 33 and the pushing bottle slide groove 31, or at the connection between the pressing bottle guide groove 42, the non-pressing bottle guide groove 43 and the pressing bottle slide groove 49. The selector cylinder is connected to the selector plate, and the selector cylinder drives the selector plate to rotate and selects different channels to be connected.

[0057] like Figure 8 , Fig. 9 Two chain guide grooves 38 are arranged on the left and right sides of the bottle pushing guide groove assembly 3. Chain guide wheels 515 are respectively installed at both ends of the bottle pushing linear guide rail 514 on each bottle pushing assembly 51. The chain guide wheel 515 is arranged in the chain guide groove 38 and slides along the chain guide groove 38. The two ends of the bottle pushing linear guide rail 514 are respectively connected to the two chains at the same time. The rotation of the chain drives the bottle pushing linear guide rail 514 to move, and under the action of the chain guide wheel 515, it rotates smoothly along the direction of the chain guide groove 38.

[0058] like Fig.15 The power assembly 2 includes a second servo motor assembly 21, a driving sprocket 222 assembly 22 and a driven sprocket 232 assembly 23, the driving sprocket 222 assembly 22 includes a driving shaft 221 and two driving sprockets 222 connected at both ends of the driving shaft 221, the driven sprocket 232 assembly 23 includes a driven shaft 231 and two driven sprockets 232 connected at both ends of the driven shaft 231, the driving sprocket 222 assembly 22 and the driven sprocket 232 assembly 23 are parallel to each other and relatively arranged on the bracket assembly 1, the second servo motor assembly 21 is connected to the driving shaft 221 on the driving sprocket 222 assembly 22 to drive the two driving sprockets 222 to rotate, and the two chains pass around the driving sprocket 222 and the driven sprocket 232 respectively.

[0059] The working process of the bottle pushing device of the present invention is as follows: the power assembly 2 drives the sprocket to rotate, and the chain connected to the sprocket runs around the left and right sides of the bottle pushing guide groove assembly 3, driving the bottle pushing assembly 51 to run along the surface of the bottle pressing guide groove assembly 4. When the bottle pushing action is required, the bottle pushing path selector connects the bottle pushing guide groove 32 with the bottle pushing chute 31, and the bottle pressing path selector connects the bottle pressing guide groove 42 with the bottle pressing chute 49. The bottle pressing driven wheel 523 first enters the bottle pressing guide groove 42, driving the bottle pressing plate 521 to move. When the bottle is pushed, the bottle pressing and lifting driven wheel 525 enters the bottle pressing and lifting guide groove 410 at the same time, driving the bottle pressing plate 521 to descend and press on the bottle, and the bottle pushing driven wheel 513 enters the bottle pushing guide groove 32, driving the bottle pushing block 511 to move to the bottle pushing position to push the bottle. After the bottle pushing is completed, the bottle pushing driven wheel 513 slides out of the bottle pushing guide groove 32, the bottle pressing driven wheel 523 slides out of the bottle pressing guide groove 42, and the bottle pressing and lifting driven wheel 525 slides out of the bottle pressing and lifting guide groove 410 at the same time, and the bottle pressing plate 521 rises. The bottle pushing block 511 returns to its original position at the same time; if there is no bottle or box at the corresponding station, no pushing action is required, the non-pushing bottle guide groove 33 of the bottle pushing selector is connected to the bottle pushing chute 31, the non-pressing bottle guide groove 43 of the bottle pressing selector is connected to the bottle pressing chute 49, the bottle pushing driven wheel 513 enters the non-pushing bottle guide groove 33, and the bottle pressing driven wheel 523 enters the non-pressing bottle guide groove 43, and no displacement in the left and right lateral directions toward the bottle pushing block 511 is generated. Accordingly, the bottle pushing block 511 and the pressing bottle selector are connected to the non-pressing bottle guide groove 43. The bottle plate 521 does not have any bottle pushing and bottle pressing actions until the bottle pushing driven wheel 513 slides out of the non-bottle pushing guide groove 33, and the bottle pressing driven wheel 523 slides out of the non-bottle pressing guide groove 43; in this way, the bottle pushing driven wheel 513, the bottle pressing driven wheel 523, and the bottle pressing lifting driven wheel 525 on each bottle pressing assembly 52 are arranged and slide in sequence on the bottle pushing guide groove assembly 3 and the bottle pressing guide groove assembly 4, and enter the bottle pushing guide groove 32, the bottle pressing guide groove 42, and the bottle pressing lifting guide groove 410, thereby completing a continuous bottle pushing process.

[0060] It should be noted that the device of the present invention, in addition to being used as a mechanism in a cartoning machine for pushing bottles, can also be used for pushing functions in other fields, such as pushing boxes and bags, etc. The shape and size of the bottle pushing block 511 and the bottle pressing block can be designed according to the specific category of the pushed items, and the solutions in which the pushing functions realized by applying the structure of the present invention are applied to other fields still fall within the protection scope of the present invention.
