Description

A smart shelf

technical field

The invention belongs to the technical field of medical equipment, and in particular relates to an intelligent shelf.

Background technique

Ordinary drug shelves have a fixed frame structure and are arranged in layers. The bottom of each layer is a fixed baffle, and medicines and other goods are placed on the fixed baffle. At present, stainless steel shelves are generally used in operating rooms to store sterile bags in layers, which has the following deficiencies:

1) Completely rely on manual operation, which consumes manpower.

2) The order of placing and picking up items requires manpower to perform multiple operations and guidance, and the process is complicated.

3) Because the instructions are not clear enough and the operation is complicated, when personnel discharge and take items, the compliance with the regulations of "take in order of expiration date" is poor.

Based on the above reasons, in clinical work, the phenomenon of incorrect ordering of items and incorrect order of personnel taking items often occurs, resulting in sterile items not being used reasonably according to the expiration date, resulting in expired items and waste.

Contents of the invention

In order to overcome the deficiencies of the prior art above, the object of the present invention is to provide an intelligent shelf, which has the characteristics of high degree of automation, labor saving, simple structure and convenient operation.

In order to achieve the above object, the technical solution adopted by the present invention is: an intelligent shelf, including a three-dimensional frame composed of four support rods, and several left transmission shafts are arranged upwardly and upwardly between the two support rods on the left side; Between the two support rods on the right side, several right transmission shafts corresponding to the position of the left transmission shaft are arranged upwardly; a transmission belt is arranged between the left transmission shaft and the right transmission shaft; the left transmission shaft is connected with the motor; Connected to the main switch.

A relay is connected between each motor and the main switch.

The support rod on the right side is provided with an in-position detection switch.

The master switch adopts three gear knobs.

There are three groups of motors, and the three groups of motors are connected to the frequency converter through three groups of AC contactors; the frequency converter is connected to the three-phase AC power supply through the power switch; The contactors are all connected with the channel selection switch; the three sets of motors are all connected with the position detection switch 6 .

The beneficial effects of the present invention are:

The present invention adopts electromechanical shelves to have the following advantages:

1) Realize automatic mechanized operation and save manpower: Using electromechanical technology, the automatic transmission of items can be realized by button operation.

2) The material and structure of the device and all components of the present invention meet the hospital infection specification requirements and performance requirements.

3) The present invention is equipped with speed control and brake induction to avoid falling objects, and is easy to operate, safe and reliable.

4) It is convenient to discharge and take items on the transmission belt, and the compliance of the staff to take them in order is improved.

Through clinical practice, electromechanical shelves have greatly saved labor, optimized the workflow, solved the long-term difficult problem of unreasonable sorting and taking order of sterile packages, and improved the management quality of sterile items.

Detailed ways

The structural principle of the present invention will be described in further detail below in conjunction with the accompanying drawings.

Referring to Figure 1, a smart shelf includes a three-dimensional frame composed of four support rods 1, and several left transmission shafts 2 are arranged upwardly and upwardly between the two support rods on the left; two support rods on the right Between the rods, several right transmission shafts 3 corresponding to the left transmission shaft 2 positions are provided at an upward interval; a transmission belt 4 is provided between the left transmission shaft and the right transmission shaft; the left transmission shaft is connected with the motor 5; The motor is connected with the main power switch. The main switch adopts three-speed knob.

A relay is connected between each motor and the main switch.

The position detection switch 6 is arranged on the support rod on the right side.

The supporting rods are made of stainless steel.

The conveyor belt is made of food-grade material.

The left transmission shaft, the right transmission shaft and the transmission belt all have three layers, the transmission mode of the transmission belt is from left to right, the speed of the transmission belt is adjustable, the support rod, the left transmission shaft, the right transmission shaft, the motor and the position detection All switches can be combined on site.

Referring to Fig. 2, there are three groups of motors, and the three groups of motors are connected to the frequency converter through three groups of AC contactors; the frequency converter is connected to the three-phase AC power supply through the power switch; the frequency converter is also connected to the reversing control switch and the speed control knob ; Three groups of AC contactors are connected with the channel selection switch;

Put the newly-incoming goods at the end of the shelf, and the shelf uses a conveyor belt to transport the goods forward. When picking up the goods, take them out from the front. Through the shelf function, the goods can be first-in-first-out.

The working principle of the present invention is:

Referring to Figure 3, after turning on the main switch, judge which shelf is to be transported according to the position of the 3rd gear knob. At this time, the relay of the corresponding shelf layer will be closed, and the relays of other layers will be disconnected. The closed relay will control the AC contactor to connect the frequency converter with the motor of the corresponding shelf layer. Adjust the speed control knob on the inverter to adjust the transmission speed of the conveyor belt according to the actual situation. Turn the 2nd gear knob of the main switch to the open position, at this time the inverter will start the three-phase motor, the three-phase motor drives the rotating shaft, and the rotating shaft drags the conveyor belt; after the conveyor belt reaches the position, the position detection switch on the shelf senses the signal, and then The induction signal will turn off the work of the conveyor belt, and the motor will stop automatically.
