Description

Technical Field

[0001] The invention belongs to the technical field of bottle making machines, in particular to a direct-drive bottle making machine and a direct-drive bottle making method. Background Art

[0002] When the bottle making machine is working, the bottle making part A and the bottle making part B respectively revolve around the axis of their chuck discs, and at the same time, the chucks of the bottle making part A and the bottle making part B respectively rotate around the axis of their chucks. Under the revolution of the chuck disc of the bottle making part A and the rotation of the chuck, the bottle making part A processes the material tube into a semi-finished bottle; under the revolution of the chuck disc of the bottle making part B and the rotation of the chuck, the bottle making part B processes the semi-finished bottle body input from the bottle making part A to the chuck of the bottle making part B into a finished bottle.

[0003] Since some processing stations of bottle making part A and part B, such as bottle mouth making station, bottle receiving station, flat bottom station, bottle unloading station and trimming station of pre-filled bottle making machine, need the chuck to stop rotating to complete the corresponding processing procedures. Therefore, the structure currently used to control the chuck rotation of bottle making part B or part A not only includes a self-rotation driving mechanism for driving the chuck to rotate, but also includes a clutch control mechanism for controlling the chuck to stop rotating. Among them, the self-rotation driving mechanism is a motor, an upper clutch connected to the power output end of the motor and connected to the outer sleeve bearing, and the clutch control mechanism is a lower clutch matched with the upper clutch, a linear moving component for controlling the upper and lower linear movement of the lower clutch, and a reset mechanism connected to the lower clutch for controlling the lower clutch to move to a contact position with the upper clutch. When the structure is used to drive the B or A chuck to rotate, the motor drives the upper clutch to rotate, the upper clutch is in close contact with the lower clutch, and the upper clutch drives the lower clutch to rotate, so that the lower clutch drives the bottle drop tube to rotate through the outer sleeve; when the clutch control mechanism is used, the linear moving component drives the lower clutch to move downward, so that the upper clutch is separated from the lower clutch, and the bottle drop tube stops rotating.

[0004] The structure for controlling the self-rotation of the bottle making part A or B in the prior art has the following defects in practical application:

[0005] The first is the complex structure. In the existing bottle making part A or B self-rotation structure, it includes a self-rotation drive mechanism for driving the B part chuck to rotate, and an additional clutch control mechanism for controlling the chuck to stop rotating is required. The overall two parts of the structure need to cooperate to realize the self-rotation control of the bottle making chuck, which makes the existing bottle making chuck self-rotation structure relatively complex, requires high precision in machine processing, and is difficult to manufacture.

[0006] The second is the low positioning accuracy. As the existing chuck control structure is relatively complex, the control of self-rotation and braking can only be achieved through the cooperation between various components. Wear is easy to occur between various mechanical components, especially the wear between the upper clutch and the lower clutch. After long-term non-stop operation and force, the gap between the two gradually increases, which greatly affects the accuracy of the rotation position of the chuck discs of the bottle making part A and part B, thereby affecting the production quality of the bottle body processed by the bottle making machine, resulting in an increase in unqualified products and reducing the production efficiency of the enterprise.

[0007] The third is that it is not easy to control. Due to the complex structure and low positioning accuracy of the existing bottle making part B, it is not easy to control the speed, rotation angle and start and stop of the chuck plate and chuck of the bottle making part B, so that the chuck plate indexing and station setting, bottle making bottom mechanism, chuck lifting and closing mechanism, chuck clutch control mechanism, bottle dropping mechanism and other components of the bottle making part B are not adjustable, so the processing accuracy of the machine parts is high, which makes the assembly and debugging of the bottle making machine difficult.

[0008] Fourth, it is impossible to produce special bottles with complex structures. Due to the poor adjustability of the mechanical components of the existing bottle making machines, when the chuck cooperates with the corresponding processing mechanism to make special bottles, bottles with complex structures or bottles with high quality requirements, especially when processing special bottles with threads, special-shaped bottles or bottles with strict product quality requirements, the existing bottle making machines are difficult to meet the production requirements, and the types of bottles processed are limited, and the scope of application is limited.

[0009] The fifth is that it is easy to cause noise pollution. The upper clutch and the lower clutch in the existing self-rotating structure have a large force running-in during operation, which will produce a large noise and easily cause noise pollution in the workshop.

[0010] Sixth, it is easy to cause energy waste. The existing bottle making part A and part B self-rotation structure does not directly convert the motor's kinetic energy into the kinetic energy to drive the chuck to rotate. Not only does it need to go through multiple levels of transmission, but when the chuck stops rotating through the clutch control mechanism, the motor continues to transmit power to the upper clutch, which obviously consumes more electricity and maintenance costs, greatly increasing the company's operating costs.

[0011] Seventh, it is easy to malfunction and inconvenient to maintain. In the production workshop, the production equipment is in a 24-hour non-stop operation most of the time, and needs to be checked and maintained frequently. After half a year or a cycle of use, the clearance and accuracy between the upper clutch and the lower clutch in the chuck self-rotation structure need to be adjusted, which greatly increases the maintenance cost; and when the rotation positioning accuracy of the chuck cannot meet the requirements, the clutch control mechanism and the self-rotation drive mechanism must be replaced, and the service life of the parts is short, which greatly increases the operation and production costs of the enterprise. Summary of the invention

[0012] In order to solve the above deficiencies in the prior art, the present invention aims to provide a direct-drive bottle making machine and a direct-drive bottle making method, so as to achieve the purpose of improving the positioning accuracy of the chuck and facilitating control.

[0013] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a direct-drive bottle making machine, comprising a bottle making part A and a bottle making part B fixedly mounted on a frame, each bottle making part A chuck and / or bottle making part B chuck is correspondingly equipped with a part A self-rotating direct-drive motor fixedly mounted on the part A chuck disk and / or a part B self-rotating direct-drive motor fixedly mounted on the part B chuck disk.

[0014] As a limitation of the present invention, the main shaft of the B-part chuck disc is fixedly mounted on the power output end of the B-part revolving direct-drive motor, and the B-part revolving direct-drive motor is fixedly mounted on the frame.

[0015] As another limitation of the present invention, the main shaft of the chuck disk of part A is fixedly mounted on the power output end of the revolving direct-drive motor of part A, and the revolving direct-drive motor of part A is fixedly mounted on the frame.

[0016] As a third limitation of the present invention, the outer sleeve of the bottle making B part chuck is assembled on the B part chuck plate through an outer bearing, a bottle drop tube key-connected to the outer sleeve is sleeved inside the outer sleeve, and an inner bearing is assembled between the outer sleeve and the bottle drop tube.

[0017] As another limitation of the present invention, the inner bearing is a linear bearing, and the outer bearing is a ball bearing.

[0018] The present invention also provides a direct-drive bottle making method implemented by the above-mentioned direct-drive bottle making machine, and its technical solution is as follows: it comprises the following steps: under the revolution of the A part chuck disk and / or the B part chuck disk, the PLC sends a signal to the corresponding A part self-rotating direct-drive motor and / or the B part self-rotating direct-drive motor to control the rotation and braking of the corresponding bottle making part A chuck and / or the bottle making part B chuck to process the bottle body.

[0019] As a limitation of the present invention, the following steps are included:

[0020] S1.PLC sends signals to the direct drive motor of part A and the direct drive motor of part B to control the revolution of the chuck plate of part A and the chuck plate of part B respectively;

[0021] S2. Under the revolution of the chuck plate of part A, the PLC sends a signal to the self-rotating direct drive motor of part A to control the self-rotation of the chuck of part A of the bottle making, and the bottle making part A processes the bottle body, and inputs the processed semi-finished bottle body into the chuck of part B of the bottle making at the bottle receiving position;

[0022] S3. Under the revolution of the chuck plate of part B, the PLC sends a signal to the self-rotating direct-drive motor of part B to control the self-rotation of the chuck of part B, and part B processes the bottle body and unloads the processed finished bottle body.

[0023] The present invention is an improvement on the existing bottle making machine. The main improvement is to improve the original mechanical transmission driving mode of the bottle making machine's rotation and revolution into a driving mode directly controlled by a direct drive motor. Due to the adoption of the above technical solution, the direct drive bottle making machine of the present invention has the following beneficial effects compared with the existing technology:

[0024] (1) The present invention adopts a direct-drive motor to directly control the rotation of the chucks of the A and B parts of the bottle making machine. There is no need to set up an additional clutch control mechanism, nor is there a need for multi-stage mechanical transmission. It can simultaneously realize automatic control of the rotation and braking of the chucks, and can directly transmit the motor driving force to the chucks. Compared with the prior art, the overall structure is simpler, which is convenient for the production and processing of machine parts, and also greatly reduces energy consumption and reduces the maintenance cost of the enterprise.

[0025] (2) Compared with the prior art in which positioning deviation exists due to multi-stage mechanical transmission, the present invention can reduce the wear between various components and greatly reduce the noise generated during operation. At the same time, it overcomes the situation in which the positioning accuracy is reduced due to wear caused by mechanical friction, improves the repeatable positioning accuracy of the chuck plate and the chuck, ensures that the chuck plate and the chuck can be repeatedly and accurately positioned to the required working position, ensures the consistency of product specifications, and improves the production quality of the processed bottle body.

[0026] (3) The present invention adopts a direct drive control method for the revolution of the chuck disc and the rotation of the chuck. The present invention facilitates the adjustment of the rotation speed, rotation angle, and start and stop of the revolution and rotation of the chuck disc and the chuck. It also enables the chuck disc indexing and station setting, bottle bottom making mechanism, chuck lifting and closing mechanism, chuck clutch control mechanism, bottle dropping mechanism and other components to be adjusted according to production needs, so that the present invention can meet the production needs of special bottles, bottles with complex structures or high quality requirements, and has a wide range of applications. At the same time, it reduces the difficulty of assembly and debugging of the bottle making machine, reduces the number of manual regular maintenance times, reduces labor, and greatly reduces production costs.
