Most automated carousel plant in Ireland takes shape at Kilsaran

In early 2021, Kilsaran commissioned their new precast plant in Kilcullen, Co. Kildare, which is the most automated precast concrete plant in Ireland. Kilsaran is Ireland’s largest independent manufacturer of a wide range of concrete products. Founded in 1964 by the late Patrick McKeown in the village of Kilsaran in County Louth, this family-owned and run business mines raw materials from its own quarries and manufactures products at its various manufacturing plants across Ireland.

The new precast concrete production facility in Kilcullen, Co. Kildare, features a new carousel plant that includes automated reinforcement and precast element production machinery as well as modern software from companies of the Progress Group.

Precast concrete produced to suit the Irish market perfectly

The carousel plant was planned in a very detailed manner and only took a short time to construct. Kilsaran spent a lot of time perfecting the efficiency of the plant as well as the precast elements it produces. It is completely BIM-oriented and not constrained by static molds. One of the most important features of the new plant is that the building dictates what precast elements are produced and not the plant itself. The plant can produce a full range of precast elements for the Irish market including solid walls, double walls, flooring solutions, as well as façade solutions.

“We manufacture the products to suit the building of the Irish market and not so suit our production,” explains James Murphy, Business Development Manager at Kilsaran Precast. Key to this vision is a production facility offering quality-assured, traceable precast elements that are manufactured with precision. Cost and environmental benefits are delivered with on-time production requiring minimal storage. Each component is constructed individually, avoiding redundant processes, to achieve maximum cost benefits. James Murphy refers to the selection of the machinery supplier: “When searching for a precast plant installer we were guided towards Progress Group by experts in the industry who noted that Progress Group were established and recognized as a market leader in precast machinery manufacture. Following our initial meetings it was clear that Progress possessed the mindset that we required. Progress demonstrated very quickly a willingness to provide an innovative plant that could manufacture multiple products efficiently at the same time. It was important for us to have an innovative partner who understands the need for development in the precast industry.”

Automation leads to high-end efficiency and quality

Progress Group came up with a carousel plant that allowed Kilsaran to produce the required range of products efficiently and automatically. The level of automation is one of its kind in Ireland and was one of the main drivers Kilsaran focused on while developing the plant together with Progress Group companies Ebawe Anlagentechnik as well as Progress Maschinen & Automation and Progress Software Development. Automation saves time on-site and guarantees dimensional accuracy, resulting in better and consistent quality. Kilsaran made sure to place robotics and automation wherever it was possible. Automation was implemented throughout the production process to make sure the quality is consistently high. At the same time, every step should be traceable, from the very inception right through to completion.

Precast concrete elements production at its best

The Progress Group shuttering system includes one for solid elements as well as one for half slabs and double walls. To produce high-quality precast concrete elements, a storage robot is used, which selects the required shutters from the shuttering storage according to the CAD data transmitted by the Ebos control system. The plotter draws outlines or other information, such as the position of built-in parts, on the shuttering surface. The Form Master shuttering robot then positions the shutters precisely on the pallet, according to the elements to be produced, and activates the integrated magnets of the shutterings. The electric sockets and magnets are installed automatically from specialized gripping tools, which ensure a highly automated outcome. Additionally, the spacers for bespoke mesh are automatically positioned on a production pallet by a robot system called Mesh Spacer. During production, a positioner takes the required number of spacers from the magazine and places them on the exact points defined by the CAD/CAM data.

The patented Infinity Line Notch-Free shuttering system of the Form Master makes centimeter-precise shuttering a reality, without the need for adding elements such as polystyrene fillers, which also complies perfectly with the various sustainability efforts of Kilsaran in general. A sophisticated combination system reduces the number of shuttering lengths used to a minimum.

A fully automatic eCon Drive concrete spreader from Ebawe Anlagentechnik accelerates the filling of the shuttering and ensures an additional level of safety for the machine operators, while at the same time saving material through exact dosing. For compaction of the freshly poured concrete, two compacting devices are installed that are suitable for variable and particularly heavy loads ensuring a high-quality element surface at the same time. For half slabs, roughing equipment is available. After curing, the pallets containing the finished precast elements are destacked from the curing rack by means of an automatically controlled pallet stacker. For the manufacture of double walls, turning equipment serves for turning the first cured skin and connecting it to the freshly poured second skin. Afterwards, the pallets still containing the finished precast panels are fed to the deshuttering robot recognizing the shutters by scanning the pallet surface and picking up the shutters fully automatically. In the next step, the wall elements are lifted by means of the tilting equipment with a movable ladder simplifying the demolding process for the operators.

The pallets are then fed to a pallet cleaning device for cleaning and the subsequent application of a release agent. The cleaned and oiled shutters are deposited length-sorted by the LPR robot back into the shuttering storage.

For insulated wall elements, the new plant at Kilsaran is equipped with an insulation material cutter that cuts the insulation plates with precision in a specially developed water-jet cutting method. The necessary CAD data are supplied by Ebos. A special 3D cutting head also allows for three-dimensional cutting processes. The advantages for Kilsaran lie in huge cost savings in material and staffing as well as less waste.

M-System  BlueMesh welding plant with integrated bending system

In order to achieve a very good reinforcement solution for the needed precast concrete elements, an automatic M-System BlueMesh mesh welding plant was installed. The mesh welding plant is operated by an MSR multirotor straightening-cutting machine for the reinforcement bars. The bars can also be cranked up lengthwise and crosswise for element slabs and welded for walls. The MSR straightening machines straighten, cut and bend rebar as well as process the reinforcing wire with a diameter of up to 16 mm directly from the coil, thus optimizing production. The strengths of the machine lie in its versatility as well as high efficiency and cost effectiveness due to low power connection values, which are achieved by inverter welding.

Innovative automated special mesh transport

Within the completely new carousel plant, equipped with the latest models of reinforcement systems, a novel concept was created together with Progress Maschinen & Automation. The requirement for the reinforcement production part of the plant was that the machine needed to produce not only straight mesh but also bent mesh for solid wall applications. Therefore, a new logistics concept was developed and implemented. This concept ensures that specially bent mesh and cages can be transported onwards automatically with a new flexible gripper. Normally, the storage gantry robot grips the mesh with the help of magnets and transports it to the next station. However, this was not possible with multi-bent mesh and overlapping reinforcement as the magnets cannot react this flexibly. With the new traverse gripper, the tongs can now flexibly access exactly where needed and can move the mesh into storage or directly into the prepared shuttering on the pallet. This new traverse system adds enormous value to Kilsaran since fewer additional bars need to be integrated by hand afterwards, and the mesh is placed automatically in the pallet, thus reducing labor requirement. This also made it possible to automate the transport to the next processing step of mesh/special mesh bent on all sides.

Software – Ebos and Stabos

Automation begins very early on in the planning phase thanks to the advanced software solutions and is implemented in the plant up until the final steps of preparing the elements for transportation. Not only is the production facility itself fully automated, but the information is delivered using the advanced PXML system. Punch Consulting works in collaboration with Kilsaran to provide BIM support and structural analysis for each building project with direct information supply to the factory. The Stabos software solution, which is now implemented with every progress reinforcement machine as a standard software since 2021, is used to record and evaluate production data. The centrally collected data can be used to increase the productivity and quality of the plant. In combination with Ebos, a comprehensive software solution for process planning, production, and process analysis that addresses all aspects of the manufacturing process from start to finish, it is possible to replace a large number of stand-alone software solutions with a perfectly integrated system. Since complex interface problems are eliminated, all work processes can be carried out in one user-friendly system.

James Murphy states: “We have faced numerous challenges during the commissioning of the plant including COVID, and we recognize the commitment from Progress Group to deliver a state-of-the-art facility for the manufacture of multiple precast products, which will serve the Irish and UK market.”
