Case palletizers are mainly used for secondary packaging applications. Most of them come as automated or robotic machines that are used to package items like bottles, bags, cases, bundles, jugs, bottles, and trays. Case palletizers are sometimes combined with case packers, conveyors, case erectors, or automatic guided vehicles for multiple handling operations.

Applications of Case Palletizers
Case palletizers are used to lift items from production lines and place or stack them perfectly onto a pallet for shipping, moving, or storing. The items can be stacked in different configurations like column-stacked, interlocked, or pin-wheel configurations. Automated case palletizers allow complex palletizing routines to be completed without the need for multiple handling operations and do not require a lot of manual labor or human supervision. These palletizers are developed to help manufacturers reallocate labor to tasks in less harmful environments, meet aggressive production requirements, and save production area floor space. The design incorporates zero pressure, non-contact accumulation roller conveyors to gently position cases prior to palletizing.
Case Palletizer Design and Customization
There are several methods used to customize the case palletizers to the needs of the manufacturing facility in which it is to be used. These customizable features can include HMI panels and data software options. Case palletizing systems provide increased line efficiency, increased production, improved quality of finished units, greater line flexibility, reduction in labor injuries, and reduction in staffing requirements.
Benefits of Using Case Palletizers
Case palletizers come either as high level or low level palletizers. High level palletizers are machines that have an infeed elevation higher than the floor or ground level, usually about 100” to 144” higher. Advantages of high level palletizers include a higher throughput relative to size of the footprint, high speed applications above 40 or 50 cases per minute, and a higher footprint than some low level palletizers. Low level palletizers (also known as floor level palletizers) usually have an entry level of about 30” to 36”. Advantages of the low level palletizers include being generally lower in cost and do not require a work platform. The maintenance for a floor palletizer is easier than a high level palletizer because the parts are easier to access. Lastly, the infeed elevation makes the low level palletizer ideal for close coupling to the case packers and case sealers.
