Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a bottle discharging mechanism of a filling equipment. Background Art

[0002] Conventional filling equipment mostly adopts a conveyor belt mode to move the bottles to be filled, and the bottle discharging is also carried out on the conveyor belt, which is relatively simple. However, in the context of aseptic filling, the conveyor belt form is mostly not applicable, and higher-level mechanisms such as drive modules are required, such as a moving pair with grooves, and the bottle body is positioned in the groove and driven by the moving pair to move between multiple workstations. The existing bottle discharging mechanism of aseptic filling equipment is to remove the bottle body from the moving pair, usually requiring two actions of clamping and rising, so the structure is relatively complex. The utility model patent with the publication number of CN206562297U discloses a liquid filling machine, and a manipulator for transferring the bottle body to the conveyor belt is also adopted as the bottle discharging mechanism in this utility model, so there is also the deficiency of complex structure. Content of the Utility Model

[0003] The existing bottle discharging mechanism of aseptic filling equipment is to remove the bottle body from the moving pair, usually requiring two actions of clamping and rising, so the structure is relatively complex. To overcome this defect, the utility model provides a bottle discharging mechanism of a filling equipment, which is simpler and more reasonable in structure.

[0004] The technical solution of the utility model is: a bottle discharging mechanism of a filling equipment, including a bottle supporting plate and a movable plate that can be lifted and lowered. The bottle supporting plate is installed on the movable plate, and there are at least two bottle supporting plates. A bottle body bayonet is formed between adjacent bottle supporting plates. The bottle discharging mechanism of this filling equipment is applicable to the production of bottle bodies with flanges at the bottle mouths, and is used to remove the bottle bodies from the grooves of the moving pair and transfer them to the next process after the production is completed. When the bottle body is conveyed from the previous process, the bottleneck is aligned with the bottle body bayonet, and the bottle body reaches below the bottle supporting plate as the moving pair moves, and the flange on the bottleneck is located above the bottle supporting plate. The movable plate can be lifted and lowered, driving the bottle supporting plate to do lifting and lowering movements. The bottle supporting plate forms a clamping connection with the flange on the bottleneck through the bottle body bayonet, so the bottle body is grabbed by the bottle supporting plate and lifted and lowered together. When the utility model works, there is only a simple lifting action, and no other clamping structures are required to assist in bottle discharging, so the structure is simpler compared with the prior art.

[0005] Preferably, a connecting rod is provided on the movable plate, and the bottle supporting plate is connected to the connecting rod. Through the connection of the connecting rod, the installation of the bottle supporting plate on the movable plate can be realized.

[0006] Preferably, a support member is provided at the top of the connecting rod, and a spacing adjustment structure is provided between the bottle supporting plate and the support member. If the connecting rod is directly in contact with the bottle supporting plate, the contact points between the connecting rod and the bottle supporting plate will be limited. The provision of the support member can increase the contact area with the bottle supporting plate, correspondingly increase the fixing points of the bottle supporting plate, enhance the stability of the bottle supporting plate, and also facilitate the setting of different forms of spacing adjustment structures. Through the spacing adjustment structure, the spacing between the bottle supporting plates can be adjusted to obtain the required width of the bottle body bayonet to adapt to the bottle mouths of different specifications of bottles.

[0007] Preferably, the spacing adjustment structure includes a positioning slot hole provided on the bottle supporting plate and a fastener threadedly connected to the support member, and the fastener penetrates through the positioning slot hole. Before the fastener is tightened, the adjacent bottle supporting plates can adjust the spacing along the long axis direction of the positioning slot hole to obtain the required width of the bottle body bayonet. This kind of spacing adjustment structure is relatively simple and easy to implement.

[0008] Preferably, a guiding and sealing member is provided on the connecting rod, and a sealing member is provided inside the guiding and sealing member. The connecting rod passes through the guiding and sealing member. When the movable plate and the bottle supporting plate perform lifting and lowering movements, the connecting rod slides inside it, and this guiding and sealing member not only plays a guiding role but also a sealing role.

[0009] Preferably, a lifting driving member is provided below the movable plate, and the output end of the lifting driving member is connected to the movable plate. The lifting driving member is the power source for lifting, driving the movable plate to perform lifting and lowering movements.

[0010] Preferably, the lifting driving member is a cylinder. The cylinder has little pollution and is more suitable for a sterile environment.

[0011] Alternatively, the lifting driving member is an oil cylinder. The oil cylinder has a strong load-bearing capacity and is suitable for operating bottles with a relatively large total weight.

[0012] Preferably, a guiding shaft is further provided on the movable plate. The guiding shaft slidably penetrates through the movable plate and is parallel to the piston rod of the lifting driving member. The lifting driving member drives the movable plate to slide on the guiding shaft to achieve lifting and lowering. The guiding shaft plays a guiding role and, in cooperation with the lifting driving member, accurately defines the lifting path of the movable plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The structure is simple and the cost is low. The present utility model has only one set of lifting actions and does not require any other clamping structures to assist in bottle discharging. Therefore, there are fewer components, the structure is simple, which is conducive to reducing the manufacturing cost.

[0015] It is suitable for a background environment with relatively high cleanliness requirements. The structure of the present utility model is reasonable, and there is a sealing structure at the lifting movement part, which can ensure that the cleanliness of the background environment is not disturbed.

A lifting driving member 1 is fixed on the fixed plate 2, and the output end of the lifting driving member 1 is hinged to the movable plate 3, enabling the movable plate 3 to lift and lower. The lifting driving member 1 is a cylinder. The bottle supporting plate 6 is composed of two pieces and is parallel. Both bottle supporting plates 6 are in the horizontal plane, and the gap between the two bottle supporting plates 6 forms a bottle body bayonet 13.

After the PLC receives the signal that the moving pair 15 is in place, the PLC controls the manipulator of the capping machine and the filling head of the filling machine to successively complete three processes: unscrewing the bottle cap, filling, and screwing the bottle cap tightly. Then, it controls the piston rod of the lifting driving part 1 to eject. The movable plate 3 drives the bottle supporting plate 6 to lift the bottle body 16, disengaging it from the groove of the moving pair 15. Then the moving pair 15 moves away, and the lifting driving part 1 retracts, driving the bottle supporting plate 6 to lower the bottle body 16.

At the same time, a new batch of empty bottle bodies 16 replace the filled bottle bodies 16, starting the next cycle.

When the next moving pair 15 arrives with a new batch of empty bottles, the end of the moving pair 15 pushes the bottle body 16 that has completed filling out of this mechanism. At the same time, a new batch of empty bottle bodies 16 replaces the bottle bodies 16 that have completed filling, starting the next cycle. If the specification of the bottle body 16 is changed and the bottleneck size varies, before the fastener 7 is tightened, the bottle supporting plate 6 is moved along the long axis direction of the positioning slot hole 12 to adjust the distance between the bottle supporting plates 6 to obtain the required width of the bottle body bayonet 13, and then the fastener 7 is tightened.

[0042] Embodiment 7:

[0043] The bottle discharging mechanism of a filling device includes a bottle supporting plate 6, a fixed plate 2, a movable plate 3 and a table plate 14. The movable plate 3 is located above the fixed plate 2, and the table plate 14 is located above the movable plate 3. A lifting driving member 1 is fixed on the fixed plate 2, and the output end of the lifting driving member 1 is hinged to the movable plate 3, so that the movable plate 3 can be lifted and lowered. The lifting driving member 1 is a cylinder. There are two parallel bottle supporting plates 6, both of which are in the horizontal plane, and the gap between the two bottle supporting plates 6 forms a bottle body clamping opening 13. There is a connecting rod 4 at each of the four corners of the top of the movable plate 3. Different from Embodiment 2, in this embodiment, there is no support member 5, and the bottle supporting plate 6 is directly connected to the top end of the connecting rod 4 through a fastener 7, so as to realize the installation of the bottle supporting plate 6 on the movable plate 3. The bottle supporting plate 6 is provided with a positioning slot hole 12, and the fastener 7 is threadedly connected to the top end of the connecting rod 4. The positioning slot hole 12 is oval, and the long axis of the positioning slot hole 12 is perpendicular to the direction of the bottle body clamping opening 13. The fastener 7 passes through the positioning slot hole 12, and the positioning slot hole 12 and the fastener 7 form a spacing adjustment structure, so that the width of the bottle body clamping opening 13 can also be adjusted. Linear bearings 9 and guide shafts 10 are also provided on both sides of the movable plate 3. The linear bearings 9 are fixedly penetrated through the movable plate 3. The bottom ends of the guide shafts 10 are fixed on both sides of the fixed plate 2, and the top ends of the guide shafts 10 are fixed on the bottom of the table plate 14. The guide shafts 10 slide through the linear bearings 9 and are parallel to the piston rod of the lifting driving member 1. The lifting driving member 1 drives the movable plate 3 to slide on the guide shafts 10 to realize lifting and lowering. The guide shafts 10 play a guiding role and cooperate with the lifting driving member 1 to accurately define the lifting path of the movable plate. A guiding seal 8 is sleeved on the connecting rod 4, and the guiding seal 8 is fixed on the surface of the table plate 14, and a seal 11 is arranged inside the guiding seal 8.

[0044] The bottle discharging mechanism of this filling device is located below the capping machine and the filling machine on a filling line, is applicable to the production of bottle bodies with flanges at the bottle mouths, and operates under the control of a PLC. The working process of this mechanism is generally as follows: The empty bottle body 16 is conveyed to this mechanism by a moving pair 15 with grooves. The bottleneck of the bottle body 16 enters the bottle body clamping opening 13, and the flange position of the bottle mouth is higher than the bottle supporting plate 6. After the PLC receives the signal that the moving pair 15 is in place, the PLC controls the manipulator of the capping machine and the filling head of the filling machine to successively complete three processes of unscrewing the bottle cap, filling, and screwing the bottle cap tightly, and then controls the piston rod of the lifting driving member 1 to eject. The movable plate 3 drives the bottle supporting plate 6 to lift the bottle body 16, disengaging it from the groove of the moving pair 15. Then the moving pair 15 moves away, and the lifting driving member 1 retracts, driving the bottle supporting plate 6 to lower the bottle body 16. When the next moving pair 15 arrives with a new batch of empty bottles, the end of the moving pair 15 pushes the filled bottle body 16 out of this mechanism, and at the same time, a new batch of empty bottle bodies 16 replace the filled bottle bodies 16 to start the next cycle. If the specification of the bottle body 16 is changed and the bottleneck size varies, before the fastener 7 is tightened, the bottle supporting plate 6 is moved along the long axis direction of the positioning slot hole 12 to adjust the spacing of the bottle supporting plate 6 to obtain the required width of the bottle body clamping opening 13, and then the fastener 7 is tightened.
