Temporarily invertible pallet tilter

The Temporary Inverted Pallet Turner is a specialized equipment used in logistics, warehousing, and production processes. Its core function is to temporarily invert the pallet and its contents to achieve tasks such as pallet replacement, cargo detachment, surface cleaning, or packaging adjustment. It combines efficiency and safety and is widely used in industries such as food, medicine, chemical, and e-commerce that require frequent stacking of goods.

1、Core working principle

The equipment completes the processing of pallet goods through the process of "mechanical clamping flip drive temporary inversion reset/unloading". The core logic is to use "temporary inversion" to solve the operational requirements that are difficult to achieve through traditional manual operations. The specific steps are as follows:

Cargo positioning and clamping: Transport pallets carrying goods (such as plastic pallets, wooden pallets) to the clamping area of the flipping machine. The equipment firmly fixes the pallets and goods through two sides or upper and lower clamping arms (equipped with anti slip rubber pads) to prevent the goods from shifting or scattering during the flipping process.

Flip drive and temporary inversion: The flipping mechanism is driven by a hydraulic motor or servo motor (usually a "0-180 ° adjustable flipping frame") to slowly flip the pallet and goods until they reach a completely inverted state of 180 °, and maintain a "temporary inversion" time of several seconds to tens of seconds according to the operation requirements (such as waiting for the old pallet to fall off when replacing the pallet, and waiting for surface impurities to fall off when cleaning).

Target homework execution: Complete core tasks in an inverted state, such as:

Replacing pallets: The old pallets are separated from the goods by gravity, and after manual or automatic removal, they are placed in new pallets;

Unloading operation: After inversion, the goods naturally detach from the pallet and fall directly into the downstream conveyor line or silo;

Surface cleaning: When inverted, dust, debris, and other impurities on the surface of the goods fall to the collection device below due to gravity.

Reset and Unloading: After the target task is completed, the flipping mechanism runs in reverse to flip the goods back to the initial forward state with the new pallet (or goods without pallets), and finally the processed goods are transported to the next stage by the conveyor line.

2、Core structure composition

The equipment structure is designed around "stable clamping, precise flipping, and safety protection", mainly consisting of 5 modules:

3、Main classifications and applicable scenarios

According to the load capacity, flipping method, and degree of automation, temporarily inverted tray flipping machines can be divided into the following categories, each with its own emphasis on applicable scenarios:

1. Classified by load capacity

Lightweight flipping machine: With a load capacity of ≤ 500kg, it is commonly used for pallet replacement or surface cleaning of lightweight goods such as small items in e-commerce (such as cardboard box stacking) and medical reagent boxes. The equipment has a small volume and is flexible to move (partially movable).

Medium sized flipping machine: with a load of 500kg-2 tons, suitable for the food industry (such as bagged flour, bottled beverage stacks), daily chemical products (laundry detergent, shampoo stacks), and often linked with production lines or storage conveyor lines.

Heavy duty flipping machine: With a load of 2-10 tons, it is used for heavy goods such as chemical (barrel coatings, adhesives), building materials (tiles, panels), etc. It adopts hydraulic drive and reinforced clamping arm to ensure stability under heavy weight.

2. Classified by degree of automation

Manual/semi-Automatic flipping machine: requires manual assistance in locating goods, operating flipping buttons, and replacing or cleaning inverted pallets. It is suitable for flexible work scenarios with small batches and multiple categories (such as small warehouses).

Fully automatic flipping machine: linked with AGV, automatic conveyor line, and pallet automatic supply device, it realizes the unmanned process of "goods entering the machine - automatic clamping - flipping inversion - pallet replacement - reset output", suitable for high-frequency operation scenarios such as large factory assembly lines and e-commerce sorting centers.

3. Classify by flipping direction

Unidirectional flipping machine: only supports a single flipping path of "forward → 180 ° inversion → forward", with a simple structure and low cost, suitable for fixed job requirements (such as only needing to replace trays).

Bidirectional flipping machine: capable of flipping at any angle from 0 to 180 degrees (such as first flipping 90 degrees to adjust the posture of the goods, and then flipping 180 degrees upside down), suitable for complex operational requirements (such as surface cleaning and pallet removal combined operation of goods).

4、Core advantages and precautions

1. Core advantages

Improve homework efficiency: Replace the traditional process of "manual disassembly pallet replacement re stacking", shorten the single homework time from 30-60 minutes to 1-5 minutes, and increase efficiency by more than 10 times.

Protecting the safety of goods and personnel: Mechanical clamping and smooth flipping prevent damage to goods caused by manual handling (such as fragile items and precision instruments), while reducing personnel bending over and carrying heavy loads, and lowering the risk of work-related injuries.

Adapt to multiple scenario requirements: Compatible with trays of different sizes (such as 1200 × 1000mm standard trays, customized shaped trays), materials (plastic, wood, metal), as well as various cargo forms such as bags, boxes, and barrels.

Reduce labor costs: Fully automatic models can reduce 1-2 full-time operators, especially suitable for regions or enterprises with high labor costs.

2. Precautions

Stability assessment of goods: Before flipping, it is necessary to confirm whether the stacking of goods is firm (such as whether the boxed goods are tightly sealed and whether the bagged goods are tied), in order to avoid the scattering of goods when flipping; Goods that are prone to deformation and leakage (such as liquid food and powder) require additional protective packaging.

Equipment parameter matching: Select the machine model with corresponding load capacity and clamping range based on the weight of the goods and the size of the pallet, to avoid overloading operation (which may cause damage to the flipping mechanism) or loose clamping (cargo displacement).

Daily maintenance: Regularly check the wear of the anti slip pad on the clamping arm (if it is severely worn, it needs to be replaced in a timely manner), the oil leakage of the hydraulic system (hydraulic oil needs to be replaced periodically), the sensitivity of the safety grating (ensure immediate shutdown after covering), and extend the service life of the equipment.

Operator training: Pre job training is required for operators to familiarize themselves with equipment operation procedures, parameter settings, and fault handling (emergency shutdown in case of cargo displacement), in order to avoid safety accidents caused by misoperation.

5、Typical application cases

Food industry: flour tray replacement

The bagged flour purchased by flour mills is usually transported on disposable wooden pallets and needs to be replaced with recyclable plastic pallets when stored. By temporarily reversing the tray flipping machine, the wooden tray and flour stack are inverted. The wooden tray falls off under the action of gravity and is manually placed on a plastic tray before resetting. A single operation only takes 2 minutes to avoid flour bag damage and dust pollution caused by manual unpacking.

Pharmaceutical industry: Surface cleaning of reagent kits

After the pharmaceutical reagent kit is produced offline, there may be residual dust or packaging debris on the surface, which needs to be cleaned before it can be stored. The flipping machine flips the stack of reagent boxes upside down for 10 seconds, allowing dust to naturally fall into the collection box below without the need for manual wiping. This not only improves cleaning efficiency but also avoids the risk of contamination caused by manual contact with the reagent boxes.

E-commerce industry: sorting and unloading of express boxes

The express box stack received by the e-commerce warehouse (loaded on wooden pallets) needs to be unloaded and enter the sorting line. The fully automatic flipping machine flips the pallet stack upside down, separates the express box from the wooden pallet, and falls into the downstream belt conveyor. The wooden pallet is automatically recycled, achieving a seamless connection between "arrival, removal, and sorting".
