Description

Technical Field

[0001] The utility model belongs to the technical field of liquid filling production lines, and particularly relates to a half clamp for a filling machine. Background Art

[0002] The filling and bottling of liquid beverages is one of the most technically demanding and quality-critical processes in the entire food and beverage production process. Taking the beer industry as an example, bottling equipment is the most technologically complex, requires the largest investment, and requires the highest management standards of all brewery production equipment. Improving equipment components in the filling process plays a significant role in optimizing operations and increasing production efficiency.

[0003] In the liquid filling production process, because the filling objects and filling containers will change, for example, in the beer canning process, the height of the filling machine's material cylinder (such as a wine cylinder) needs to be adaptively adjusted for different bottle types to meet the filling needs of beer bottles of different heights, such as raising or lowering the filling machine's material cylinder (such as a wine cylinder). This process is generally called a line change in the filling process of the filling machine. Therefore, during each line change of the filling machine, the operator needs to stop the filling machine first, and then use tools such as wrenches or pliers to unscrew or tighten the fastening screws on the half clamp to operate the half clamp so that the half clamp cooperates with the lugs of the clamping part of the material cylinder (such as a wine cylinder) to complete the line change of the filling machine. However, because existing half clamps are secured with screws, and each filling machine cylinder has at least six half clamps, each with two screws on either side, a single line change requires adjusting the half clamp's screws up to 24 times. This is cumbersome, time-consuming, and labor-intensive. Furthermore, the removed screws are scattered and easily scattered or lost, leading to frequent screw damage, thread stripping, slipping, and other faults and potential safety hazards, seriously impacting the overall line change schedule and production safety of the filling machine. Furthermore, traditional half clamp operation is labor-intensive and results in significant downtime. Utility Model Content

[0004] In order to solve the above-mentioned defects of the screw fixing method of the Huff clamp in the prior art, the purpose of the present utility model is to provide a new Huff clamp for a filling machine, which adopts a new structure and a string pin fixing method to solve the above-mentioned technical problems. The present utility model provides a new Huff clamp.

[0005] Generally, the working states of a filling machine can be divided into two types: one is the filling state; the other is the line change state. In actual filling operations, the filling machine needs to be adaptively debugged and the material cylinder (such as a wine cylinder) needs to be lifted and lowered according to the shape changes of the specific filling object container to meet different filling needs. Among them, the filling state is the working state in which the filling machine starts the filling operation after being debugged in place, such as filling beer, beverages, etc. At this time, the position of the filling machine's material cylinder (such as a wine cylinder) remains fixed; the line change state is when it is necessary to switch to filling containers of different shapes, such as for different bottle shapes, the filling machine's material cylinder (such as a wine cylinder) is debugged and lifted. At this time, the filling machine is in a stopped state. It can only resume the filling operation after the switching and debugging are completed. The shorter this process is, the smaller the impact on filling efficiency. Huff clamps are often required during the line change process. Huff clamps are commonly used devices on filling machines in the fields of beverage, beer, condiments, and oil filling.

[0006] The utility model provides a half clamp for a filling machine, comprising a clamping device 17, a supporting device 18 and a positioning pin 7, and is characterized in that the clamping device 17 comprises a movable rod 3 and a clamping head 2 fixedly connected to one end of the movable rod 3, and a positioning hole 5 is provided on the movable rod 3 for receiving the positioning pin 7; the supporting device 18 comprises a support rod 6 and a limiting portion 4 fixedly connected to one end of the support rod; wherein the movable rod 3 passes through the limiting portion 4 and is installed in cooperation with the supporting device 18, and the positioning pin 7 is used to position the displacement of the movable rod 3 relative to the limiting portion 4.

[0007] In some specific embodiments, after the positioning pin 7 is installed in the positioning hole 5 , the minimum distance between the center line of the positioning hole 5 and the tangent line of the movable rod 3 and the limiting portion 4 on the side close to the positioning hole 5 is 1-5 mm.

[0008] In some specific embodiments, the limiting portion 4 is a hollow structure that matches the outer contour of the movable rod 3 .

[0009] In some specific embodiments, at least one operating handle 13 is provided on one side of the free end of the movable rod 3 for operating the movement of the movable rod 3 in the limiting portion 4 .

[0010] In some specific embodiments, the positioning pin 7 is provided with an anti-loss component 15 , and both ends of the anti-loss component 15 are detachably connected to the pin head of the positioning pin 7 and the limiting portion 4 .

[0011] Furthermore, the anti-loss component 15 is one of a rope, a chain, a belt, and a steel wire.

[0012] In some specific embodiments, the diameter of the positioning hole 5 is 2 to 10 mm.

[0013] In some specific embodiments, a limiting groove 8 is provided on the movable rod 3, and a limiting hole 16 is provided on the limiting portion 4. The limiting member 14 cooperates with the limiting groove 8 through the limiting hole 16 to limit the displacement of the movable rod 3 and the limiting portion 4.

[0014] In some specific embodiments, the positioning hole 5 is a blind hole or a through hole.

[0015] In some specific embodiments, the positioning pin 7 is one of a cylindrical pin, a conical pin, a pin with a hole, and a cotter pin.

[0016] like Figure 5 、 6 As shown, the control ring 10 is an annular stainless steel bracket (partially shown in the figure) for installing filling control components such as the filling valve pneumatic opening / closing components, electrical detection components, bottle bursting nozzle system, and half clamps around the material cylinder (such as a wine cylinder) of the filling machine. Its cross-section is generally rectangular. The half clamp 1 is fixedly connected to the control ring 10 by fastening screws and a fixing plate 11. Specifically, a threaded hole for installing and fixing the half clamp 1 is provided on the support rod 6 of the half clamp 1, and a movable "ㄈ"-shaped fixing plate 11 is provided on the control ring 10. One side opening of the fixing plate 11 is clamped on the control ring 10, and a fastening threaded hole corresponding to the threaded hole of the support rod 6 of the half clamp 1 is provided on the fixing plate 11. The fastening threaded hole is generally a blind hole for fastening screws to pass through the connecting fixing plate 11. Of course, it can also be a through hole, but generally a blind hole is more preferred. The fastening screw passes through the threaded hole on the support rod 6 of the half clamp 1 and is connected to the fastening threaded hole on the fixing plate 11, and cooperates with the fixing plate 11 to fix the half clamp 1 on the control ring 10. In addition, in addition to the connection method disclosed above, other commonly used connection methods in the art that can achieve a stable connection between the control ring 10 and the support rod 6 are applicable to this patent.

[0017] During the specific line change process, the operator needs to use the half clamp 1 to clamp the lug 12 of the cylinder 9 ( Figure 5 ), the filling machine loading cylinder (such as a wine cylinder) 9 is relatively fixedly connected to the control ring 10 through the half clamp 1, and then the operator operates the motor on the cylinder (such as a wine cylinder) to drive the transmission gear to lift the cylinder (such as a wine cylinder). The half clamp 1 and the lug 12 are tightly engaged with each other under the drive of the motor of the cylinder 9, and the cylinder 9 and the control ring 10 are synchronously lifted and lowered through the half clamp 1 to complete the line change operation of filling.

[0018] When the line is changed, the filling machine switches to the filling state. At this time, the clamping part 2 of the half clamp 1 needs to be disengaged from the lug 12 and as far away from the lug 12 as possible. At the same time, the positioning pin 7 needs to be used to position the half clamp 1 on the limit part to prevent the clamping head 2 from accidentally extending during the filling process and damaging the control components on the filling machine, such as the pneumatic opening / closing assembly of the filling valve, the electrical detection element, the bottle explosion nozzle system, etc. In addition, the positional relationship and connection method of components such as the material cylinder, support rod, and control ring can be connected using the conventional filling machine connection method commonly used in the filling machine industry (as described in the utility model patent CN202152270U, which is incorporated herein by reference in its entirety).

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. It effectively simplifies the operation steps and processes of the half clamp during the line change process, making the operation simpler, more convenient and faster, greatly reducing the downtime of line change and improving filling efficiency;

[0021] 2. Reduce the labor intensity of operators and improve the safety and reliability of half clamp operation.

[0022] 3. It avoids the possibility that the operation time may be affected by the occasional loss of the half clamp screws, as well as the risk of safety accidents.

[0033] Example 1

[0034] like Figure 1 and 4As shown, the half clamp for a filling machine of this embodiment is applied to the field of beer filling technology. The half clamp 1 is divided into three parts: a clamping device 17, a supporting device 18 and a positioning pin 7. Among them, the clamping device includes: a clamping head 2 and a movable rod 3. The movable rod 3 has a cylindrical outer contour, and the clamping head 2 and the movable rod 3 are welded together to form an integrated structure; the supporting device includes: a limiting part 4 and a support rod 6. The limiting part 4 is a hollow ring-shaped structure, and the limiting part 4 and the support rod 6 are welded and fixed to form an integrated structure. Of course, the clamping device 17 and the supporting device 18 can also be integrally formed by a casting process, as long as the strength and size meet the filling requirements. The movable rod 3 passes through the limiting portion 4, and one end connected to the clamping head 2 is used to cooperate with the lug 12 to complete the clamping work during the line change process. The other end is a free end, and one or more operating handles 13 can be provided on the side of its end to push or pull back the movable rod 3 during the actual line change process to facilitate the operation of the clamping device 17 clamping and disengaging the lug 12. If the free end of the movable rod 3 is provided with an operating handle 13, the movable rod 3 needs to be assembled into the limiting portion 4 during the half clamp processing. Otherwise, after the processing is completed, the assembly of the clamping device 17 and the supporting device 18 will not be completed due to the existence of the operating handle 13. Alternatively, one side of the limiting portion 4 is provided as an open structure to facilitate the installation and removal of the movable rod 3, but the stability of the half clamp is worse than that of the one-piece structure. In addition, a positioning hole 5 is also provided on the movable rod 3 to receive the positioning pin 7 to limit the relative movement of the movable rod 3 in the limiting portion 4.

[0035] When the filling machine needs to change lines, that is, the filling machine is working in the line change state, the operator first needs to remove the positioning pin 7 to release the movable rod 3, and then the operator can use the free end of the movable rod 3 (that is, the other end of the movable rod 3 connected to the clamping head 2) One or more operating handles 13 set on the side to push the movable rod 3 toward the material cylinder 9, so that the clamping head 2 is combined with the lug 12 of the clamping part of the material cylinder, so that when changing the line and adjusting the position of the material cylinder 9, other devices such as the control ring 10 can be adjusted at the same time. Of course, if the operating handle 13 is not set, the movable rod 3 itself can also be directly pushed and pulled to complete the engagement and disengagement of the clamping head 2 and the lug 12.

[0036] In the line-changing state, the clamping head 2 needs to be combined with the lug 12 of the clamping part of the cylinder. The operator pulls out the positioning pin 7 from the positioning hole 5 and puts it down gently. Since the positioning pin 7 is connected to the limiting part 4 through an anti-loss component 15, such as a stainless steel chain, rope, chain, belt, steel wire, etc., the positioning pin will not be lost or slipped. Of course, the length of the anti-loss component 15 should not be too long, so that the operator can easily take and place the positioning pin 7.

[0037] The position and connection relationship of the half clamp and other related parts are as follows Figure 5As shown. After the filling machine line change is completed, it enters the normal filling working state. The operator needs to separate the half clamp 1 from the clamping lug 12 of the material cylinder (such as a wine cylinder) 9. The operator can use the operating handle 13 to retract the clamping head 2 and make it close to the limiting part 4. At this time, the movable rod 3 moves in the annular hollow structure of the limiting part 4. When the clamping head 2 is as close to the limiting part 4 as possible, the positioning hole 5 is also exposed from the outside of the limiting part 4 (close to the other side of the clamping head) or is a distance away from the edge of the limiting part 4 close to the positioning hole 5 side. At this time, the operator inserts the positioning pin 7 into the positioning hole 5 to position the movement of the movable rod 3 to prevent the movable rod 3 from extending forward and damaging the control components on the filling machine due to machine vibration and other reasons during the filling state.

[0038] Since the positioning hole 5 is a through hole, the positioning pin 7 is exposed from the other end after being inserted. At the same time, because the pin head of the positioning pin 7 is a large ring structure, the size is significantly larger than the aperture of the positioning hole 5 (such as the aperture is 5mm), so the pin head of the positioning pin 7 can be stuck outside the aperture of the positioning hole 5 and will not slide out through the positioning hole 5. Since the positioning hole 5 is precisely drilled, after the positioning pin 7 is installed in the positioning hole 5, the minimum distance between the center line of the positioning hole 5 and the tangent of the movable rod 3 and the limiting part 4 on the side close to the positioning hole 5 is 1-5mm, that is, the minimum straight-line distance between the positioning pin 7 and the clamping head 2 after being inserted into the positioning hole 5 should not be too large. Therefore, after the positioning pin 7 is inserted, the various components of the half clamp 1 can maintain a relatively tight and stable structure.

[0039] Example 2

[0040] On the basis of embodiment 1, this embodiment further provides a limiting groove 8 (such as Figure 2 As shown), the limiting portion 4 is provided with a limiting hole 16 and a limiting member 14 (as shown Figure 3 As shown, the limiting member 14 can be a limiting pin or other component that can cooperate with the limiting slot 8 to achieve rapid limiting and removal. The limiting slot 8 is provided corresponding to the limiting hole 16. The limiting member 14 is inserted into the limiting slot 8 through the limiting hole 16 provided on the limiting portion 4 and abuts against the limiting slot 8, thereby achieving relative fixation between the limiting portion 4 and the half clamp movable rod 3, and preventing the half clamp from rotating relative to the limiting portion 4.

[0041] Example 3

[0042] comparison Figure 1 In this embodiment, the through hole of the positioning hole 5 of embodiment 1 can be set as a blind hole, and the hole diameter can be set to 10 mm, which can also achieve the effect of the utility model.

[0043] The new half clamp provided by the utility model eliminates the need for on-site operators to repeatedly loosen and tighten up to 24 screws on the half clamp when changing lines. A single line changing operation can save at least 10 minutes of line changing time and downtime. According to the overall line changing standard of 80 minutes for the wine filling machine, the line changing time of the wine filling machine can be shortened by 12.5%, thereby improving the production efficiency of filling, reducing the labor intensity of on-site operators, and avoiding unexpected downtime caused by accidents such as loss and damage of screws during the line changing process.

[0044] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
