In recent years, with the continuous popularity of the Internet, e-commerce has developed rapidly. Customers’ order commodities show the characteristics of many varieties, few batches and short delivery period, which makes the storage density of the shelves in the supplier’s logistics distribution center continuously improve. The frequency of materials entering and leaving the warehouse is increasing. The number of small parts picking is increasing day by day. More and more logistics distribution centers use the shuttle car based goods to people picking system.

Clamping telescopic forks are widely used in automatic storage equipment such as stereo warehouse multi-layer shuttle cars, shelf type bins AGV, RGV, and mini load. The maximum weight of the material box held by HEGERLS can reach 50Kg. The clamping width of the fork arm can be adjusted arbitrarily within the range of 200~600mm. The maximum picking travel is 840mm. The maximum operating speed of the telescopic fork is 1.5m/s, and the acceleration is 1.2m/s ²。 The operating noise is controlled within 75dB, which can meet the requirements of most single and double extension racks. HEGERLS can also customize the multi-layer shuttle car stereoscopic warehouse of the gripping telescopic fork box according to the specific requirements of customers, such as the gripping width, picking stroke and other parameters.
The parts in the Hiygris HEGERLS gripped telescopic fork box multi-layer shuttle car stereo warehouse The telescopic fork is a telescopic mechanism used in the stereo warehouse and the logistics automatic storage system for material storage or transfer. It has flexible two-way automatic expansion function and accurate limit function! It can be directly mounted on the stacker, or mounted on a fixed lifting mechanism, or mounted on a mobile lifting platform. The stacker runs through the roadway between shelves to automatically access or transfer items! It can be connected with production line system and enterprise management system. It uses computer and barcode technology (encoder) to realize information intelligent management and operation!
About HEGERLS Clamping Telescopic Fork
HEGERLS telescopic gripper fork is a unique kind of fork in the series of telescopic forks of stackers, namely, a two-way automatic telescopic gripper fork, also known as a holding gripper fork or a holding gripper fork, a fork fork or a fork fork. It is a fork specially used for the transfer of small bins. It can be directly assembled on a multi-storey picking AGV or other working platforms, with the expansion of the fork arm and the clutch of the lever (hook), Complete the access or transfer action!
The HEGERLS gripper fork is mostly made of aluminum alloy, featuring small size, light weight, fast running speed and smooth expansion. At the same time, it also adopts the principle of multi motor synchronization, realizing that the same telescopic fork mechanism can be used to transfer or access boxes of different specifications. It not only effectively improves the storage efficiency, but also greatly improves the space utilization rate of storage, especially for high-rise intensive Intelligent warehousing!
HEGERLS clip on telescopic fork structure
The structure of HEGERLS gripper fork can be divided into deep storage location and shallow storage location. A deep storage location is a storage location with two material boxes, and a shallow storage location is a storage location with one material box. That is, a deep storage location can clamp two material boxes at a time, while a shallow storage location can only clamp one material box at a time. The difference between the HEGERLS gripper fork and the ordinary duplex telescopic fork is that the finger pulling fork is still composed of three fork bodies, namely, the inner fork body, the middle fork body and the outer fork body, except that the front fork body has one more pull rod (hook), which is matched with the guide rail (slide rail), roller bar, synchronous wheel, synchronous belt, fluent bar, shift rod (hook), jacking shaft, wheel bar, drive motor (servo), shift rod motor The detection instrument and other components form a complete telescopic mechanism, which cooperates with the telescopic fork arm and the clutch of the lever (hook) to complete the access or transfer action!
Working principle of HEGERLS clip on telescopic fork
The fork arm of the HEGERLS gripper fork is side standing and connected laterally by guide rail. Through control, the guide rail can slide back and forth to adjust the distance between the two fork arms of the fork, so as to achieve the common use of a fork for multi specification material boxes! When picking up materials, the fork extends to the material storage position, the retaining hook (lever) automatically lowers and blocks the end face of the carton or plastic box, and then the fork retracts, dragging the carton or plastic box to the middle of the fork, and then moves out in reverse according to the degree requirements, the hook (lever) is pulled back, and the fork retracts again to complete the task of picking up or transferring! Although the principle of the gripper fork is the same as that of the ordinary telescopic fork, the transmission parts, connecting rods and other components of the finger fork are greatly different. It is used to describe that the chain wheel, chain, gear, rack, etc. are all replaced by synchronous wheels, synchronous belts, etc., while the sliding arm uses guide rails, and the fork body materials are all replaced by metal sheets or aluminum alloy materials, so the weight of the gripper fork is only about 80kg.
In addition, it should be noted that during the design of the gripper type telescopic fork, the size of the dense storage shelves, the vertical position of the shelves with boxes, the track level and the size of the boxes should be combined to determine the overall parameters of the extension forks (extension fork movement, box spacing, fork width, fork internal width, fork height, etc.), so as to meet the needs of containers on the shelves. Clamping fork can only transfer or access the products packaged in cartons or plastic boxes effectively, and cannot transfer irregular materials. In addition, the volume and weight of the transferred material box should not be too large, and the load weight should not exceed 100KG! The height of the clamping fork is generally designed according to the height of the bin!
