Description

Technical Field

[0001] The present invention relates to a track positioning device and method for a bin transfer machine. More specifically, it relates to a multi-bin parallel dynamic composting process that utilizes a unique bin transfer machine track surface structure, in conjunction with a universal current monitoring instrument, to accurately and reliably complete the bin transfer process without manual on-site operation. Background Art

[0002] Composting technology is divided into two categories: dynamic composting and static composting. Dynamic composting uses compost turning equipment to achieve the mixing and stacking of compost materials. When multiple bins are connected in parallel, the compost turning equipment must use a bin transfer machine to complete the bin transfer process to achieve the purpose of one machine serving multiple bins.

[0003] Traditionally, the positioning of a transfer machine is achieved manually on-site. This method offers the advantage of high reliability, but the disadvantage is the high temperature, high humidity, and toxic and hazardous gases surrounding the fermentation chamber, posing a high risk to the operator's occupational health and safety.

[0004] In recent years, some industrial composting projects have adopted optical, electromagnetic and other precision sensors in an attempt to achieve unmanned automatic transfer of warehouses. However, due to the harsh on-site environmental conditions, the service life and reliability of the sensors are insufficient, making them prone to failures and even accidents. Summary of the Invention

[0005] In view of this, the main purpose of the present invention is to provide a transfer machine track positioning device and method, which, through the unique transfer machine walking track surface structure, cooperates with the universal current monitoring instrument, and can accurately and reliably complete the transfer process without manual work on site.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a transfer machine track positioning device is provided, including: a main positioning groove, a slave positioning groove, and a transfer machine horizontal track. The transfer machine carries the turning equipment and walks on the horizontal track surface of the transfer machine. The current of the transfer machine walking motor is in a stable state of horizontal walking. When the driving wheel of the transfer machine passes through the slave positioning groove, the current of the transfer machine walking motor first decreases and then increases relative to the horizontal track surface. When the driving wheel of the transfer machine passes through the slave positioning groove, the current returns to a stable state of horizontal walking, and the transfer machine carries the turning equipment and continues to walk on the horizontal track surface. When the driving wheel of the machine enters the main positioning groove, the current of the travel motor of the transfer machine decreases significantly relative to the horizontal track surface. The control system of the transfer machine automatically stops after sensing the current change, and the transfer machine is put into position. The compost turning equipment carried by the transfer machine automatically enters the fermentation bin to work. After completing the work in the fermentation bin, the compost turning equipment automatically returns to the transfer machine, and the transfer machine automatically starts to move. At this time, the current of the travel motor of the transfer machine increases first and then decreases relative to the horizontal track surface. When the driving wheel of the transfer machine passes the main positioning groove, the current returns to a stable horizontal walking state, and the transfer machine carries the compost turning equipment to the next fermentation bin. The above process achieves the following goals: (1) The transfer machine realizes unmanned automatic control. (2) While increasing the system reliability through mechanical positioning, the current signal is associated. (3) The current signal can be transmitted and collected through the travel motor cable, which greatly increases the reliability.

[0007] Among them, the above-mentioned main positioning groove is a groove on the walking track surface of the transfer machine. Its overall shape is an arc. The radius of the arc is the same as the radius of the walking wheel of the transfer machine. The height of the positioning groove is 1-100mm. The position of the main positioning groove is calibrated by the positioning of the fermentation bin it serves to achieve precise positioning of the transfer machine.

[0008] Among them, the above-mentioned secondary positioning groove is a groove on the walking track surface of the transfer machine. Its overall shape is horizontally stretched on the basis of the main positioning groove, and the bottom is horizontal, so as to reduce the processing and installation of the transfer machine and the accuracy requirements of the transfer machine position calibration. The arc radius is the same as the radius of the walking wheel of the transfer machine. The length of the horizontal part of the bottom is 5-500mm and the height of the positioning groove is 1-100mm.

The transfer machine 4 carries the turning equipment and walks on the horizontal track surface of the transfer machine. The current of the transfer machine 4 walking motor is in a stable state of horizontal walking. When the driving wheel of the transfer machine 4 passes through the secondary positioning groove 2, the current of the transfer machine 4 walking motor first decreases and then increases relative to the horizontal track surface. When the driving wheel of the transfer machine 4 passes through the secondary positioning groove 2, the current returns to a stable state of horizontal walking. The transfer machine 4 carries the turning equipment and continues to walk on the horizontal track surface. When the driving wheel of the transfer machine 4 enters the main positioning groove 1, the current of the transfer machine walking motor increases relative to the horizontal track surface. When the road surface is significantly lowered, the control system of the transfer bin machine senses the current change and automatically stops, completing the placement of the transfer bin machine 4. The compost turning equipment carried by the transfer bin machine 4 automatically enters the fermentation bin to work. After completing the work in the fermentation bin, the compost turning equipment automatically returns to the transfer bin machine 4, and the transfer bin machine 4 automatically starts to move. At this time, the current of the transfer bin machine's walking motor increases first and then decreases relative to the horizontal track surface. When the driving wheel of the transfer bin machine 4 passes through the main positioning groove 1, the current returns to a horizontal walking stable state, and the transfer bin machine 4 carries the compost turning equipment and moves to the next fermentation bin. The above process achieves the following purposes: (1) The transfer bin machine realizes unmanned automatic control. (2) While increasing the system reliability through mechanical positioning, the current signal is associated. (3) The current signal can be transmitted and collected through the walking motor cable, which greatly increases the reliability.
