Description

Technical Field

[0001] This utility model relates to the field of automated packaging equipment technology, and in particular to a partition lifting device for auxiliary conveying. Background Technology

[0002] In modern beer and beverage bottling lines, automated palletizers stack products layer by layer. To enhance stack stability and prevent collapse and wear during transport, a partition plate (pad) is typically placed between each layer. Currently, partition plates are mostly supplied manually or by semi-automatic equipment, which presents the following problems: manual placement is labor-intensive, inefficient, and difficult to match with high-speed production lines; while common semi-automatic supply equipment lacks effective partition storage and automatic lifting mechanisms. When a partition plate is removed, the stack height decreases, requiring frequent shutdowns for manual replenishment, affecting production continuity; furthermore, partition plates are prone to shifting or tipping during stacking and lifting, leading to retrieval failures and affecting the stable operation of the production line. Utility Model Content

[0003] (1) Technical solution

[0004] To solve the above-mentioned technical problems, this utility model provides a partition plate lifting device for auxiliary conveying, including a frame, a partition plate positioning assembly fixed on the frame for positioning the partition plates, a lifting platform disposed inside the frame for carrying stacked partition plates, and a drive unit for driving the vertical movement of the lifting platform. The drive unit includes a lifting motor and a lead screw mechanism driven by the lifting motor.

[0005] Preferably, the frame includes a first frame, a second frame, and a crossbar. The first frame and the second frame are arranged vertically and symmetrically. The crossbar is located on the back of the frame and connects the first frame and the second frame.

[0006] Preferably, the partition positioning assembly includes a set of partition positioning rods, which are vertically arranged and fixed on the crossbar.

[0007] Preferably, the lead screw mechanism is installed on both the first frame and the second frame. The lead screw mechanism is a ball screw pair, which includes a lead screw and a nut. The output shaft of the lifting motor is connected to the lower end of the lead screw, and the two nuts are fixedly connected to both sides of the lifting platform.

[0008] Preferably, the drive unit further includes guide rails, and a pair of guide rails are installed on both the first frame and the second frame. The two sides of the lifting platform are slidably connected to the guide rails by sliders.

[0009] (2) Beneficial effects

[0010] This utility model provides a partition plate lifting device for auxiliary conveying. Compared with the prior art, this utility model has the following advantages:

[0011] 1. By controlling the lifting platform with the drive unit, the drop in material pile height caused by the removal of the partition can be compensated, so that the top partition is always kept at a fixed optimal material picking height, realizing continuous automated supply of partitions, reducing downtime and improving production efficiency.

[0012] 2. The platform adopts a dual ball screw synchronous drive combined with a four-rail structure, which makes the lifting platform more stable during the lifting process, can withstand heavy-duty partition stacks, and has good rigidity, making it less prone to shaking or tilting.

[0013] 3. The partition stack is constrained from the rear by the partition positioning rod fixed on the crossbar. This structure is particularly suitable for partitions that do not have positioning holes, effectively solving the problem that partitions without holes are prone to displacement and tipping during lifting and lowering, and has higher versatility.

[0014] 4. The first and second frames are connected by crossbars at the back, forming a robust frame structure that ensures the stability and reliability of the equipment under long-term heavy-load operation. Attached Figure Description

[0020] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1-4As shown, the partition plate lifting device for auxiliary conveying of this utility model includes a frame, a partition plate positioning assembly fixed on the frame for positioning the partition plates, a lifting platform 5 disposed inside the frame for carrying stacked partition plates, and a drive unit for driving the lifting platform 5 to move vertically. The drive unit includes a lifting motor 10 and a lead screw mechanism driven by the lifting motor 10.

[0022] The frame includes a first frame 1, a second frame 2, and a crossbar 3. The first frame 1 and the second frame 2 are placed vertically and symmetrically on the left and right. The crossbar 3 is welded to the middle of the back of the first frame 1 and the second frame 2, which firmly connects the two into an integral frame, greatly enhancing the rigidity of the frame.

[0023] The partition positioning assembly includes a set of partition positioning rods 4, which are vertically arranged and fixed to the crossbar 3. The partition positioning rods 4 extend vertically downward, with their bottom ends close to but not in contact with the lowest position of the lifting platform 5. They are arranged behind the load-bearing area of ​​the lifting platform 5, forming an invisible "guardrail".

[0024] The lead screw mechanism is installed on both the first frame 1 and the second frame 2. The lead screw mechanism is a ball screw pair, which includes a lead screw 6 and a nut 7. The output shaft of the lifting motor 10 (a servo motor) is connected to the lower end of the corresponding lead screw 6 through a coupling. The two nuts 7 are fixedly connected to both sides of the lifting platform 5. The two lifting motors 10 are respectively fixed to the bottom of the first frame 1 and the second frame 2.

[0025] The drive unit also includes guide rails 8. A pair of guide rails 8 are installed on both the first frame 1 and the second frame 2. The two sides of the lifting platform 5 are slidably connected to the guide rails 8 through sliders 9.

[0026] Working Principle: Initially, the lifting platform 5 is in a lower position. The operator places a stack of partition boards on the lifting platform 5 and positions the stack against the back of the frame, ensuring its sides contact the partition positioning rod 4. After the system starts, the lifting motor 10 rotates synchronously, driving the lifting platform 5 vertically upward along the guide rail 8 via the transmission of the lead screw 6 and nut 7, until the top partition board reaches the preset material handling height and stops. Throughout the lifting process, the partition positioning rod 4 always abuts against the stack of partition boards from the side and rear, preventing it from tilting backward or shifting position due to inertia or vibration.

[0027] After the robotic arm removes one or more partitions, the control system (such as a PLC) restarts the lifting motor 10, precisely raising the lifting platform 5 a corresponding distance so that the new top partition returns to the preset picking height. This cycle repeats, achieving uninterrupted material supply. This invention also includes a sensor for detecting the height of the top layer of the partition stack. The sensor is electrically connected to the control system, which controls the start / stop and rotation of the lifting motor 10 based on the sensor's feedback signal. The sensor is either an ultrasonic sensor or a photoelectric sensor.

[0028] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
