Description

Technical Field

[0001] This utility model relates to the testing technology of food packaging machinery and equipment, and in particular to a device for detecting the position of the cutter of a filling machine. Background Technology

[0002] The Tetra Pak TBA200 series pillow pack filling machine has won market favor due to its superior production efficiency and wide applicability. Traditional Tetra Pak filling machines have certain limitations, typically lacking a cutter position detection device. In actual operation, the cutter inside the filling machine inevitably faces various wear and tear due to prolonged and high-frequency use, making it prone to malfunction. Once the cutter malfunctions, its position is highly likely to shift and fail to automatically return to the normal working position. Under normal operating conditions, the cutter is located inside the equipment and cannot be directly observed by the operator, which may lead to the cutter being exposed, resulting in incomplete cutting or poor sealing of the packaging material.

[0003] Currently, the Tetra Pak pillow pack filling machine TBA200 series generally adopts manual timed unpacking and inspection to address this issue. This process is not only cumbersome and increases the workload of workers, but also has randomness and cannot guarantee 100% detection of leakage caused by cutter problems.

[0004] To address the aforementioned shortcomings and problems, there is an urgent need to design a cutting blade position detection device for filling machines, so as to accurately determine the working status of the cutting blade in the filling machine in real time, thereby providing strong support for food packaging production.

Detailed Implementation

[0027] To make the technical solutions and advantages of the embodiments of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0028] Example 1, Reference Figure 1-4 This embodiment describes a filling machine cutter position detection device, which includes a filling machine gripper device and a cutter detection device;

[0029] The filling machine gripper device includes a cutter 13 and a gripper frame 14. The gripper frame 14 is provided with grippers that reciprocate on a chain, and the front end of the grippers holds the cutter 13.

[0030] The cutter detection device includes a shaft 1, a bushing 2, a support plate 3, a clamping block 4, a contact plate 5, an L-shaped transverse side plate 6, a contact plate rod 7, an insulating sleeve 12, and a signal transmission device.

[0031] The two ends of the shaft 1 pass through the gripper frame 14 and are locked in relative position by nuts. A bushing 2 is fitted on the shaft 1.

[0032] The support plate 3 is fixedly connected to the bushing 2, and the contact plate 5 is clamped on the support plate 3 by the clamping block 4. The clamping block 4 and the support plate 3 are fixedly connected by the fastening screw 9.

[0033] The L-shaped transverse side plate 6 is fixedly connected to the shaft 1. The contact plate rod 7 is installed at the front end of the L-shaped transverse side plate 6 and is covered with an insulating sleeve 12. The contact plate rod 7 and the contact plate 5 are at a 90-degree angle and are in contact with each other.

[0034] The signal transmission device includes a wiring screw 10 and a wiring nut 11. The wiring nut 11 is connected to the wiring screw 10 and installed on the front side plate of the L-shaped horizontal side plate 6. A sensor is provided at the position where the contact plate rod 7 is connected to the L-shaped horizontal side plate 6. The sensor is connected to the PLC via the wiring nut 11 and the wiring screw 10 through a signal line.

[0035] Furthermore, retaining rings 8 are provided at both ends of the bushing 2.

[0036] Furthermore, the gap between the contact plate 5 and the gripper is set to 1.2-1.5mm.

[0037] Furthermore, the PLC is connected to the filling machine equipment.

[0038] Furthermore, the cutter detection device is externally equipped with a waterproof photoelectric monitor, a power distribution box, and a buzzer alarm system connected to the PLC.

[0039] Furthermore, the material of the cutter detection device is food-grade stainless steel.

[0040] The present invention utilizes mechanical contacts to monitor the status of the cutter 13. The specific method is as follows:

[0041] When the cutter 13 is operating normally, the contact plate rod 7 is in contact with the contact plate 5, and the monitoring device is in a normally closed state. When the cutter 13 is not reset, the chain drives the contact plate 5 to rotate through the cutter 13, causing the contact plate rod 7 to separate from the contact plate 5. At this time, the monitoring device is in a normally open state. The sensor detects the abnormality and feeds the signal back to the PLC through the signal transmission device to achieve the alarm effect.

[0042] When an alarm occurs in this device, the indicator light corresponding to the PLC output point will light up, and at the same time, the buzzer alarm system will sound an alarm. The PLC outputs a feedback signal to the filling machine to stop it. The buzzer alarm sound allows operators to detect the alarm information in a timely manner and respond quickly, even from a distance.

[0043] This utility model device has low modification cost. It achieves high-precision and low-cost detection through mechanical contact monitoring, which can effectively avoid problems such as incomplete cutting or poor sealing of packaging materials caused by the cutter not resetting, and reduce the labor cost caused by manual monitoring.

[0044] The ease of operation of this device further ensures production stability and provides a solid guarantee for improving product quality.
