Sauce Bottling Equipment

This sauce bottling equipment integrates the liquid-filling station with the pump-dispenser installation station, linked by a conveying system. This allows bottles to move directly from the filling stage to the installation area, eliminating the need for manual or intermediate transfers between separate machines.

The system utilizes a single-station filling process, with the filling head precisely controlling the output volume based on pre-set parameters. Downstream, a specialized capping mechanism-designed for pump dispensers-secures the pump to the bottle's threaded neck through a combination of mechanical gripping and rotation. The entire workflow is structured according to the standard packaging sequence for such products, making it ideal for manufacturers of items that utilize dispensing pumps, such as those for lotions, hand soaps, or shampoos.

Unlike equipment designed solely for standard bottle caps, this machine's capping unit is engineered to account for the specific external dimensions of the pump dispenser, its optimal gripping points, the bottle's thread specifications, and the required tightening depth. Consequently, the capping tooling can be custom-designed to suit the unique structure of any specific pump dispenser.

Empty bottles are conveyed into the workstation, where a positioning mechanism secures the bottle body and aligns the bottle opening. Once the presence of a bottle is confirmed, the filling unit is activated; the filling nozzle descends into the bottle, and filling begins. Upon reaching the target volume, the nozzle retracts, and an anti-drip valve closes. A brief pause follows to allow any residual liquid at the bottle opening to drain back, minimizing the risk of product residue on the threaded area.
Following the completion of the filling process, the pump supply system releases the pump head. The pump head is transported along a guided track to the assembly station, where a flexible pre-assembly mechanism gently lowers it onto the bottle opening. The pump head is aligned with the opening, allowing the dip tube to hang naturally and ensuring coaxial alignment; at this stage, the threads are only loosely engaged, with no tightening force applied.
Once the components are correctly positioned, a signal triggers the servo-driven capping unit to descend, with gripping jaws securing the outer wall of the pump head. The servo system continuously monitors the torque as the pump is screwed onto the threads at a constant speed. When the torque reaches a pre-set threshold, the capping motion stops immediately, and the servo motor releases its force to prevent any excessive torque from damaging the pump structure.
Once capping is complete, the gripping jaws release, the bottle positioning mechanism disengages, and the finished product moves downstream. The system then resets, awaiting the arrival of the next bottle.

Servo-driven metering pumps ensure a consistent volumetric output, with a valve assembly providing independent control over dispensing and cut-off; the filling nozzles support a submerged, slow-dispensing mode to minimize liquid foaming.

Filling, conveying, and capping operations are carried out in a set sequence, with clearly defined tasks for each workstation. By monitoring the equipment during operation, one can inspect specific stations-facilitating the diagnosis of issues such as incomplete filling, bottle misalignment, or improper installation of pump heads.

This component controls the vertical movement of the filling head, allowing the filling nozzle to align with the bottle opening for dispensing. Adjusting the height of the filling head enables the system to accommodate bottles of various heights.

Guide rails are used to restrict the movement path of bottles and reduce wobbling during transport. The gap between the guide rails on either side can be adjusted based on the width or diameter of the bottles.
