Problems solved by technology
[0003] The forks used in the existing cargo transfer equipment mostly use encoders to monitor the telescopic speed and positioning limit of the forks. The cost of this type of data-based information monitoring system is relatively high. The noise requirements are high, and the data equipment needs to be repaired and maintained regularly, and the cost of use is also high

Embodiment 1
[0035] Example 1, such as figure 1 As shown, the three-dimensional warehouse roadway stacker adopting the fork control method described in the present application, the three-dimensional warehouse roadway stacker includes a lower beam and ground rail assembly 100 and an upper beam and sky rail assembly 400, a set of opposite The set front column 200 and rear column 500 are movably connected between the front column 200 and the rear column 500, and the cargo platform 300 that can be lifted vertically is arranged on the cargo platform 300 and can reciprocate and transport goods horizontally. Fork 600.
[0036] According to the different conveying directions of goods in and out of the stacker, two sets of fork controls with the same structure are installed on the loading platform 300, which can be respectively extended to both sides (including extending and retracting the fork to the left, extending and retracting the fork to the right). ) fork 600.

The invention discloses a pallet fork control method. An output shaft of a drive motor is sleeved with a coded disc coaxial with a drive sprocket. A plurality of gaps evenly distributed in the circumference are formed in the edge of the coded disc. A proximity switch is oppositely installed on the coded disc. A neutral-position left detection switch, a left in-place detection switch, a right in-place detection switch and a neutral-position right detection switch are installed on a lower fork body. The neutral-position left detection switch and the neutral-position right detection switch are symmetrically installed along the transverse center line of the lower fork body. The distance between the left in-place detection switch and the transverse center line of the lower fork body is equal tothat between the right in-place detection switch and the transverse center line of the lower fork body. A right in-place detection block, a neutral-position detection bar and a left in-place detection block are installed on a middle fork body. The distance between the right in-place detection block and the transverse center line of the middle fork body is equal to that between the left in-place detection block and the transverse center line of the middle fork body. The transverse center line of the neutral-position detection bar coincides with the transverse center line of the middle fork body. Detection signals of the proximity switch form signal sets with intervals due to the fact that the signals are shielded by the coded disc. The fork discharging speed and the fork stretching lengthcan be calculated according to the interval time and the interval number in the signal sets.
Description
technical field [0001] The invention relates to the improvement of a fork control method applied to horizontal or vertical conveying equipment, and belongs to the field of logistics storage. Background technique [0002] With the rapid development of e-commerce logistics and production automation technology, the scale of cargo sorting and conveyor line systems is getting larger and larger. In the horizontal or vertical conveying equipment of the three-dimensional warehouse, forks are widely used for cargo transfer. For example, the roadway stacker uses the fork to lift the goods and transfer them to the loading platform. After reaching the height of the storage work station, the fork will move the goods to the docking equipment or the cargo position, so as to realize the difference between different stations. of transshipment. [0003] The forks used in the existing cargo transfer equipment mostly use encoders to monitor the telescoping speed and positioning limit of the f...
