Abstract

The utility model discloses a tunnel formula stacker is with preventing goods protection system that falls, carry cargo bed, fork, left side laser ranging sensor, right side laser ranging sensor, analog input module, analog output module, alarm and controller including the stacker. The laser ranging sensor monitors the position of goods on the shelf cross beam in real time, when the stacker is getting goods or putting goods, when the goods position changes abnormally, the control system timely generates alarm information at the moment, triggers the alarm to alarm, and the fork stops stretching out, so that the goods are prevented from being taken out to be separated from the shelf cross beam to cause the goods to fall. The scheme is convenient and simple, safe and reliable, and can effectively avoid most conditions of falling of goods.

Description

Tunnel type stacker prevents goods protection system that falls

Technical Field

The utility model belongs to logistics equipment automatic control field, concretely relates to protection system that goods falls is prevented to tunnel formula stacker.

Background

As core equipment in an automatic warehouse logistics system, the stability of a roadway stacker directly influences the stability of the whole system. Most systems are normal when used in the early period, and after the system is used for a period of time, due to the influences of factors such as warehouse foundation settlement, deformation of a shelf beam, inclination of a goods carrying platform of the stacker and the like, when the stacker takes or puts goods on different rows of the same layer of shelves, some places are normal, and the positions of some places are low or high, so that the forks and the goods are rubbed. The condition can lead to the goods to fall seriously, in case of the accident, will bring huge loss.

The prior art does not have a device for automatically monitoring goods aiming at the condition at present.

SUMMERY OF THE UTILITY MODEL

The utility model provides a protection system that tunnel formula stacker prevented goods and fall to the problem that above-mentioned prior art exists, prevents that the goods from falling.

The technical scheme of the utility model:

a protection system for preventing goods from falling for a tunnel type stacker comprises a left laser ranging sensor, a right laser ranging sensor, an analog quantity input module, a field bus and a controller, wherein the left laser ranging sensor is arranged in the middle of the left side of a goods carrying table; the controller is connected with the alarm through the digital quantity output module.

The left laser ranging sensor detects the position of the goods on the left shelf beam in real time, the right laser ranging sensor detects the position of the goods on the right shelf beam in real time, and the information of the positions of the goods is transmitted to the stacker controller in real time through the analog input module and the field bus. When the stacker takes the goods and stretches out the fork, and when the detected goods position change value is larger than 30mm, the controller timely generates alarm information, triggers the alarm to alarm, and the fork stops withdrawing. When the stacker finishes goods placing and withdraws the fork, and when the detected goods position change value is larger than 30mm, the controller timely generates alarm information, triggers the alarm to alarm, and the fork stops withdrawing.

The utility model discloses a method that the goods on laser rangefinder sensor to goods shelves carries out real-time supervision prevents that the goods from falling, and the scheme is convenient simple, and safe and reliable can effectively avoid most goods condition of falling to take place.

Drawings

Fig. 1 is a schematic view of the mechanical structure of the present invention.

Fig. 2 is a schematic diagram of the control structure of the present invention.

In the figure: the system comprises a cargo carrying table 1, a left laser ranging sensor 2, a pallet fork 3, a right laser ranging sensor 4, an alarm 5, an analog input module 6, a digital output module 7 and a controller 8.

Detailed Description

The invention will be further described with reference to the following examples of the drawings.

As shown in fig. 1 and 2: the utility model provides a protection system that tunnel formula stacker prevented goods and falls, is including setting up in the left side laser range sensor 2 of carrying 1 left side intermediate position of cargo bed and setting up in the right side laser range sensor 4 of carrying 1 right side intermediate position of cargo bed, and left side laser range sensor 2 and right side laser range sensor 4 are connected with controller 8, and controller 8 is connected with alarm 5 that is used for exporting alarm information.

Specifically, the left laser ranging sensor 2 and the right laser ranging sensor 4 are connected with the controller 8 through the analog input module 6, and the analog input module 6 is connected with the controller 8 through the field bus. The controller 8 is connected with the alarm 8 through the digital output module 7, and the digital output module 7 is connected with the controller 8 through a field bus. The analog input module 6 and the digital output module 7 adopt a structure form commonly used in the technical field.

During the concrete implementation, be used for detecting the position of the goods on the goods shelves of carrying cargo bed 1 left side through left side laser sensor 2, right side laser sensor 4 is used for detecting the position goods position of the goods on the goods shelves of carrying cargo bed 1 right side. The position information is transmitted to the stacker controller 8 in real time through the analog input module 6 via the field bus.

When the stacker withdraws the fork 3 after goods are put on the left goods shelf, the position value of the goods measured by the left laser ranging sensor 2 cannot be changed. But if the stacker position is lower than normal, after the stacker had put the goods, 3 fork when retrieving rub with the goods, 3 fork can take the goods out, and the position value that left side laser ranging sensor 2 measured will take place great change this moment, if the change value is greater than 30mm, 8 timely production alarm information of controller this moment trigger alarm 5 and report to the police, and the fork stops retrieving, prevents that the goods from being taken out and breaking away from the goods shelves crossbeam and leading to the goods to fall. The detection principle when the stacker puts goods to the right side shelf and the fork 3 is retrieved is similar to that of the left side.

When the stacker is stopped stably and ready to extend out of the fork to take goods from the left goods shelf, the position value of the goods measured by the left laser ranging sensor 2 cannot be changed. But if the stacker position is on the high side, the stacker fork stretches out the in-process, fork 3 and goods friction, and fork 3 can drive the goods, and the position value that left side laser range sensor 2 measured will take place great change this moment, if the change value is greater than 30mm, controller 8 in time produces alarm information this moment, triggers alarm 5 and reports to the police, and the fork stops stretching out, prevents that the goods from being taken out and break away from the goods shelves crossbeam and leading to the goods to fall. The detection principle when the stacker stretches out to the right side goods shelf goods taking fork 3 is similar to that of the left side.

There are many factors that affect the falling of the goods caused by the friction between the fork 3 and the shelf beam when the fork is extended and retracted, and there is no good method for avoiding the accident in the prior art. And the utility model discloses can prevent effectively that the stacker goods when getting goods and putting goods from falling, reduce the loss that does not need.
