Description

A sorting device for warehouse logistics supply chain

technical field

The utility model relates to the technical field of logistics equipment, in particular to a sorting device for warehouse logistics supply chain.

Background technique

In the express logistics industry, it is an important workflow to separate and store packages in different cities according to different regions. Existing automated or semi-automated logistics parcel sorting equipment, especially semi-automatic parcel sorting equipment is a very common way to place several parcels on the electric conveyor line of the sorting equipment from front to back through other equipment or manually When different packages pass through multiple detection stations on the conveyor line of the sorting equipment, the main control circuit board identifiers of the sorting equipment based on QR codes or radio frequency tags at the upper end of the multiple detection stations respectively pass through the lower end in turn. The package is identified according to the corresponding address information of different two-dimensional barcodes or radio frequency tags. After the identification is correct, the main control circuit board then controls the matching cylinder of the sorting equipment to push the corresponding package to the left or right through its piston rod and detect it on the conveyor line. The discharge port of the station falls (when the package and the main control circuit board of the detection station need to be pushed down from the discharge port of the detection station, according to the different installation positions, the first channel of the main control circuit board The output terminal of the power supply outputs power for a period of time to the power input terminal of the solenoid valve at the left or right end of the cylinder, and then after the solenoid valve at the left or right end of the cylinder is energized, the compressed air enters the left or right end of the cylinder, and the piston rod moves to the right. Or move to the left to push the package into the box, and then the second power output terminal of the main control circuit board outputs power for a period of time to the solenoid valve power input terminal at the right or left end of the cylinder, and then the solenoid valve at the right or left end of the cylinder gets After power on, compressed air enters the right or left end of the cylinder and the piston rod moves to the left or right to return to the initial position, ready for the next time the package is pushed into the box), and the upper end of the side end of the station is open In the sorting box of the formula structure (for example, each station sorting box corresponds to a package in a city and other areas, and the cylinder piston rod returns to the initial position after pushing), and then completes the sorting and storage of packages by address.

The movement mode of the existing sorting equipment to push the goods generally adopts the cylinder, because the working mode of the cylinder is driven by compressed air, so, because it needs to be equipped with air compressors and other equipment, it also needs to be connected to the corresponding pipelines, which not only occupies a valuable sorting area space, the overall equipment cost will also increase, and more importantly, the compressed air drives the cylinder piston rod to move faster, so that if the items in the pushed package are vulnerable to damage, it is easy to cause damage to the product ( For example, if the package contains items packed in cartons, there is a chance that the packaging box and the items inside will be damaged due to excessive driving force and too fast speed, etc.) and will adversely affect the sorting work. Finally, after the sorting equipment is filled with the sorted items in the matching sorting box (the upper end is open), the staff needs to manually replace the empty sorting box. Since the existing sorting equipment does not have a package The function of reminding the staff when it is full, so that when the staff does not find out the situation in the sorting box in time, the package will fall on the ground, which will also have an adverse effect on the sorting work. To sum up, it is particularly necessary to provide a sorting device that can reduce the impact of pushing items into the sorting box, and can promptly prompt the staff to replace the empty sorting box after the parcels in the sorting box are full. .

As shown in Figures 1 and 2, other working principles and working processes of the semi-automatic parcel sorting equipment body of the present utility model are completely consistent with the existing semi-automatic parcel sorting equipment. In the new model, a number of packages are placed on the electric conveyor line 1 of the sorting equipment from front to back through other equipment or manually, and are transported forward. At the same time, the identifier 10 of the main control circuit board A7 of the main control circuit board A7 based on the two-dimensional code or the radio frequency tag sorting device at the upper end of the multiple detection stations (located in the upper middle of the rear end of the support frame) respectively checks the packages that pass through the lower end sequentially according to the Identify the address information corresponding to different two-dimensional barcodes or radio frequency tags, and then separately control the flexible conveying mechanism to move the corresponding packages from the corresponding detection stations on the conveyor line according to the corresponding address information of different two-dimensional barcodes or radio frequency tags The discharge port of the station falls and enters the sorting box with an open structure at the upper end of the side of the station (for example, each station sorting box corresponds to a package in a city and other regions), and then completes the sorting and storage of the parcels by address.

As shown in Figures 1 and 2, in this model, after the 220V AC power enters the power input pins 1 and 2 of the stabilized power supply A1, the stabilized voltage power supply A1 outputs stable DC 12V power from pins 3 and 4 under the action of its internal circuit. The control circuit, the prompt circuit, and the power supply input terminal of the main control circuit board A7. When the conveying roller or conveyor belt of the electric conveyor line 1 transports several packages at a certain distance from the back to the front, the front package passes the lower end of the identifier 10, and the package needs to be released at the detection station after the main control circuit board A7 recognizes it. The power supply (such as 4 seconds) output by the first power supply output terminal of the main control circuit board A7 for a certain period of time after the material port is discharged will enter the 3 and 4 pins of the time relay module A4, so the time relay module A4 will be triggered by its 9 Under the action of the internal circuit and the output power time set by the technician, the pin will output power for a certain period of time (such as 6 seconds) into the positive power input terminals of photoelectric switches A2 and A3, and enter the positive pole of relay K4 through unidirectional conduction through diode VD1 The power input terminal, therefore, the relay K4 is energized and closed, and within 6 seconds when the control power input terminal and the normally open contact end are closed, the two sets of motor reduction mechanisms M2 will be energized to work, and the power output shaft drives the endless belt clockwise Rotate (the guide roller guides the belt movement and ensures that the belt has a certain tension), ready for the subsequent push of the package.

As shown in Figures 1 and 2, when the photoelectric switches A2 and A3 are energized, when the package is located at the lower end of the photoelectric switch A2 and A3, if the distance between the upper end of the package and the detection head of the photoelectric switch A2 is too large (for example, more than 3 cm ), the pin 3 of the photoelectric switch A2 will output a high level and enter the positive power input terminal of the relay K1, so the relay K1 is powered and its two control power input terminals and the two normally open contact terminals are closed respectively, and then the two sets of electric The positive and negative poles of the telescopic rod M1 are energized, and the piston rod drives the housing 3 and the endless belt to move downward and the distance between the upper end of the package and the upper end of the package is close. Pin 3 stops outputting high level, and then the relay K1 loses power and no longer pulls in its control power input terminal and normally open contact terminal to open the circuit, then the shell 3 and the endless belt will no longer move and are at a suitable height to ensure that the follow-up is effective for the package Push from right to left (at this height, when the package is continuously conveyed forward to the lower end of the housing by the electric conveyor line, the upper end of the package is just in effective contact with the lower end of the belt). In reality. When the package is located at the lower end of the photoelectric switch A2 and A3 (the height of the lower end of the detection head of the photoelectric switch A2 and A3 and the height of the upper end of the conveying line are greater than the height of the package), if the distance between the upper end of the package and the detection head of the photoelectric switch A3 is too small (such as less than 2.8 cm), the pin 3 of the photoelectric switch A3 will output a high level and enter the positive power input terminal of the relay K2, so the two control power input terminals and the two normally open contact terminals of the relay K2 are energized and closed respectively, and then the two The negative and positive poles of the set of electric telescopic rod M1 are energized, and the piston rod drives the housing 3 and the ring belt to move upward and the distance between the upper end of the package is slightly enlarged. When the distance between the upper end of the package and the detection head of the photoelectric switch A2 is greater than 2.8 cm, the photoelectric Pin 3 of switch A3 stops outputting high level, and then relay K2 loses power and no longer pulls in its control power input terminal and normally open contact terminal to open the circuit, then the shell 3 and the endless belt will no longer move and are at a suitable height to ensure the follow-up Effectively push the package from right to left (at this height, when the package is continuously conveyed forward to the lower end of the housing by the electric conveyor line, the upper end of the package just touches the lower end of the belt). Through the above, within 6 seconds, the new model can make the lower end of the belt and the upper end of the package (generally plastic packaging bag or paper packaging bag, with better elasticity) be at a suitable distance, and the lower end of the subsequent belt can effectively contact the upper end of the package ( Slightly press the package down) and act on the package to ensure that subsequent packages are pushed into the sorting box. When the electric conveying line continues to push the package forward (usually 2 seconds) to the lower end of the rotating belt 6, the lower end of the belt 6 will push the corresponding package horizontally from right to left through the outlet of the corresponding detection station and drop it at the corresponding point. Pick box. After 4 seconds, the first power supply output terminal of the main control circuit board A7 stops outputting power, and the 3 and 4 pins of the corresponding time relay module A7 will stop outputting power after 6 seconds because there is no trigger power supply, and the photoelectric switch A2, A3, relays K1, K2 and motor reducer M2 (electric telescopic rod M1 does not work) all lose power and no longer work, and get ready for pushing the next package.

As shown in Figures 1 and 2, when the sorted packages enter the sorting box at a certain time interval, if the corresponding number of packages is small and the height is low Every time a single package falls into the sorting box, it will temporarily block the infrared beam emitted by the photoelectric switch AA5, and the pin 3 of the photoelectric switch AA5 outputs a high level to charge the capacitor C1 through the resistor R1 to reduce the voltage and limit the current, but every two A package falls at a certain time interval, which will cause the power supply charged by the capacitor C to be released last time, and the subsequent stage relay K3 will not lose power. In the present model, in the initial state of the trigger composed of time base integrated circuit A6, diode VD (providing a bypass for the discharge of capacitor C), resistor R1, etc., because capacitor C is not fully charged, pin 2 of time base integrated circuit A6 is at low Potential, then the trigger is in the set state, and the pin 3 of the time base integrated circuit A6 outputs a high level through the resistor R2 to step down and limit the current to enter the base of the NPN transistor Q1, and the NPN transistor Q1 is turned on and the collector outputs a low level to enter the relay K3 Negative power supply input terminal, the relay K3 is energized and its control power supply input terminal and the normally closed contact end are open, so the sounder B will not be energized and sound. In practice, when the sorting box is full of parcels and the distance between the upper parcel and the lower end of the detection head of the photoelectric switch AA5 is less than 35 cm, the pin 3 of the photoelectric switch AA5 will continuously output a high level through the resistor R1 to reduce the voltage and limit the current. Charge the capacitor C with an interval of 3 seconds. After the capacitor C is fully charged, the trigger is reset, and the pin 3 of the time-base integrated circuit A6 stops outputting high level, and then the base of the NPN transistor Q1 is cut off, and the relay K3 loses power and no longer absorbs it. If the control power input terminal and the normally closed contact terminal are closed, then the buzzer B will give a loud prompting sound, reminding the staff that the parcels in the sorting box are about to be full, and a new sorting box should be replaced in time to prevent the parcels from falling On the ground (after replacing the new sorting box, the detection head of the photoelectric switch AA5 has no continuous package blocking, so the sounder B will no longer make a sound).

In Fig. 2, relays K1, K2, K3, K4 are DC12V relays. Photoelectric switch A2, A3 and photoelectric switch A5 are PNP type infrared reflective photoelectric switch products of model E3K50-50, the working voltage is DC 12V, and it has three connecting wires, two of which 1 and 2 pins are power input wires, and the other 3 The foot is the signal output line. The lower end of the photoelectric switch has a detection head. When it is working, the emission head of the detection head will emit infrared beams. Blocking, after receiving by the receiving head parallel to the detection head, the signal output line 3 pin will output high level or not output high level (photoelectric switch A3 output, photoelectric switch A2 does not output, photoelectric switch AA5 output) or there is no object blocking At this time, pin 3 of the signal output line does not output high level or output high level (the photoelectric switch A3 does not output, the photoelectric switch A2 outputs, and the photoelectric switch AA5 does not output). The detection distance of its detection head becomes closer when it is adjusted to the left, and the detection distance of its detection head becomes farther when it is adjusted to the right. The electric telescopic rod M1 is a reciprocating electric push rod with a working voltage of DC 12V and a power of 100W. The models of diodes VD1 and VD are 1N4007 and 1N4148 respectively.
