Description

Technical Field

[0001] The utility model relates to the field of intelligent warehousing, in particular to a full-automatic intelligent warehousing system. Background Art

[0002] With the development of technology, intelligent warehousing technology has become more and more mature. Inside a manufacturing enterprise, the on-site warehousing and distribution center is integrated with the enterprise production workshop to establish a warehousing and logistics management system integrating functions such as material inbound and outbound, online inventory management, and intelligent material automatic distribution, which has become a new type of intelligent warehousing system model. When integrating the warehousing and distribution center and the enterprise production workshop, an air shower room needs to be set at the integration point. Especially in workshops with high cleanliness requirements, it is necessary to strictly control that there is no direct air convection between the enterprise production workshop and the warehousing and distribution center to reduce the pollution problems brought by entering and leaving the workshop. To achieve automatic material distribution, it is necessary to ensure that the passage between the enterprise production workshop and the warehousing and distribution center can be connected at any time when the material arrives. After the material enters the air shower room, the doors on both sides are closed, and at the same time, the incoming material is blown. In the prior art, both the outer door and the inner door of the air shower room are manually opened and closed, and cannot be automatically opened and closed. Moreover, the existing air shower room does not have a communication interface and cannot realize the signal connection between the air shower door and the peripheral system. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a full-automatic intelligent warehousing system that can effectively integrate the warehousing and distribution center and the production workshop and realize the automatic opening and closing of the passage.

[0004] The technical solution adopted by the utility model is that the utility model includes a warehousing and distribution center, a clean workshop, and an AGV. The AGV is driven to operate through the RCS system of the warehouse. The AGV shuttles between the warehousing and distribution center and the clean workshop to transport materials. An air shower room is arranged at the entrance of the clean workshop. An outer door and an inner door are respectively arranged on the outer side and the inner side of the air shower room. Automatic door closers are arranged on both the outer door and the inner door. An air shower door controller is arranged at the air shower room. The air shower door controller is electrically connected to the RCS system and the automatic door closer respectively.

[0005] As can be seen from the above solution, by setting a cargo shower door controller in the cargo shower, the cargo shower door controller is used to control the outer door and the inner door of the cargo shower, so as to realize the automatic opening and closing control of the inner and outer doors of the cargo shower; in addition, the cargo shower door controller is signal-connected to the RCS system, that is, the control of the cargo shower is connected to the RCS system, and the control of the inner door and the outer door of the cargo shower is coordinated with the RCS system. When the AGV arrives outside the outer door of the cargo shower, the cargo shower door controller can be automatically triggered to send a control signal, and finally the RCS system and the cargo shower are linked to form a whole, so that the cargo shower door can execute according to the signal of the RCS system and feedback the execution result; effectively integrating the warehousing and distribution center and the production workshop, and realizing the automatic opening and closing of the passage.

[0006] Further, the following are installed on the cargo shower door controller:

[0007] A switch door circuit for controlling the opening and closing of the outer door and the inner door of the cargo shower door through the automatic door closer;

[0008] An opening-in-place signal feedback circuit for sensing whether the outer door and the inner door of the cargo shower door are in place when opened;

[0009] A double-door interlock circuit for controlling the opening and closing of the outer door and the inner door of the cargo shower door to keep the internal space of the cargo shower clean; and

[0010] An air shower circuit for controlling the start and stop of the blower of the cargo shower door.

[0011] As can be seen from the above solution, through the automatic control device of the warehousing cargo shower door composed of the switch door circuit, the opening-in-place signal feedback circuit, the double-door interlock circuit and the air shower circuit, the connection between the RCS system of the warehousing and the cargo shower door is established. When the outer door is opened from outside the workshop by using the work of the automatic control device of the warehousing cargo shower door, the inner door is automatically locked. After entering the cargo shower and closing the outer door, the air shower is automatically started inside the cargo shower and stops when the set time is reached. During the air shower, the inner door and the outer door are locked at the same time and neither side can open the door. After the air shower ends, both the inner door and the outer door are unlocked, and the inner door is opened to enter the workshop. The moment the inner door is opened, the outer door is automatically locked. After the inner door is closed, the cargo shower door enters the standby state and the inner and outer doors are unlocked; when the inner door is opened from inside the workshop, the outer door is automatically locked. After entering the cargo shower and closing the inner door, the inner door is unlocked. The moment the outer door is pushed open from inside the cargo shower, the inner door is automatically locked. After walking out of the cargo shower and closing the outer door, the inner door is automatically unlocked and returns to the standby state; it can be seen that the structure of the present utility model is simple, and only a controller needs to be added to the existing cargo shower door to realize the above automation functions; compared with the prior art, both the outer door and the inner door of the cargo shower door realize automatic opening and closing, providing guarantee for the subsequent automatic and safe passage of the AGV car through the cargo shower door and avoiding collision.

[0012] Further, the door opening and closing circuit includes a controller terminal connected to the RCS system of the warehouse, a fifth intermediate relay, and a sixth intermediate relay. The 5th contact of the fifth intermediate relay is connected to the 1st contact of the sixth intermediate relay. Light-emitting diodes are provided on both the fifth intermediate relay and the sixth intermediate relay.

[0013] As can be seen from the above solution, the door opening signal sent by the RCS system of the warehouse acts on the fifth intermediate relay and forms a self-locking through the sixth intermediate relay, which is equivalent to the automatic door closer always executing the door opening instruction to keep the door in the normally open state. The door closing signal sent by the RCS system of the warehouse will act on the sixth intermediate relay. After the sixth intermediate relay operates, the self-locking is released, "COM" and the "access control signal" are disconnected, and the automatic door closer can start to execute the door closing action; the outer door or the inner door of the air shower door realizes the opening or closing action.

[0014] Further, the door opening in-place signal feedback circuit includes a door opening in-place position sensor. The door opening in-place position sensor is connected to the RCS system of the warehouse through the controller terminal. When the door opening in-place position sensor detects a metal object, it outputs a low level, indicating that the door is opened in place. As can be seen from the above solution, the position sensor is used to sense the opening position of the door. When the door opening in-place position sensor detects a metal object, it outputs a low level, indicating that the door is opened in place; the generation of the feedback signal is realized, so that the process of opening and closing the door forms a closed-loop process, ensuring the use safety of the air shower door.

[0015] Still further, the double-door interlock circuit includes a first intermediate relay and an inner door position sensor. A light-emitting diode is connected to the inner door position sensor. The first intermediate relay and the inner door position sensor are connected to the RCS system of the warehouse through the controller terminal. By using the interlock circuit, the interaction between the inner door and the outer door of the air shower door is realized to ensure that the air inside the air shower door cannot circulate directly, ensuring the cleanliness of the air shower room.

[0016] In addition, the air shower circuit includes a second intermediate relay, a first time relay, and an outer door position sensor. The power supply circuit of the AC contactor of the blower of the air shower door is connected in series between the normally open contact of the second intermediate relay and the normally closed contact of the first time relay. The second intermediate relay, the first time relay, and the outer door position sensor are respectively connected to the RCS system of the warehouse through the controller terminal. The air shower circuit is used to control the opening and closing of the blower in the air shower door, combined with the rhythm of the opening and closing of the outer door and the inner door of the air shower door, to ensure that the air shower room is always dust-free. At the same time, the compact linkage of the blower, the outer door, and the inner door ensures the time rhythm and reduces the time cost.

[0017] Furthermore, the full-automatic intelligent warehousing system further includes a lamp control circuit, which includes a seventh intermediate relay, an eighth intermediate relay, and a second time relay. The seventh intermediate relay, the eighth intermediate relay, and the second time relay are connected in sequence. The normally open contact of the eighth intermediate relay is linked to the lamp control circuit to control the lighting and extinguishing of the lamp tube. The second time relay is an electrified delay relay, and the seventh intermediate relay is driven by a logical OR gate circuit composed of the first intermediate relay and the second intermediate relay. Thus, it can be seen that since the lights do not need to be turned on for a long time, they only need to be turned on when there are people or goods passing through the air shower door, and the lights are turned off when the air shower door is on standby. When the inner door or the outer door is opened, the lights are always on. After both the inner and outer doors are closed, the lamp tube lights up for a set period of time and then turns off automatically, thereby enabling the air shower room to have better energy-saving effects.

[0025] As Figures 1 to 7 shown, it includes a warehousing and distribution center 1, a clean workshop 2, and an AGV 3. The AGV 3 is driven to operate through the RCS system of the warehouse. The AGV 3 shuttles between the warehousing and distribution center 1 and the clean workshop 2 to transport materials. An air shower room 4 is provided at the entrance of the clean workshop 2. An outer door and an inner door are respectively arranged on the outer side and the inner side of the air shower room 4. Automatic door closers are arranged on both the outer door and the inner door. An air shower door controller is arranged at the air shower room 4. The air shower door controller is respectively electrically connected to the RCS system and the automatic door closer.

[0026] Here, an electric door closer is installed on each door of the air shower room, and the action of the door closer drives the opening and closing of the door leaf. The door closer can be controlled by manual push sensing, buttons, and remote control. The automatic door closers are paired in pairs and are connected through the double-door synchronization function. Controlling one of them will cause the other to act synchronously.

[0027] When the "COM" and "access control signal" output by the RCS system in the warehouse are short-circuited, the door closer performs the opening action. The two interfaces are respectively connected to normally open buttons. When the buttons are pressed, the two places are connected, and the door closer performs the opening action. When these two contacts are disconnected, the door closer automatically performs the closing action after a delay period, and the delay time is adjustable. The present utility model also controls the opening and closing of the door by controlling the on-off of these two contacts.

[0028] The air shower door controller is equipped with:

[0029] A switch door circuit for controlling the opening and closing of the outer door and the inner door of the air shower door through the automatic door closer;

[0030] An opening-in-place signal feedback circuit for sensing whether the outer door and the inner door of the air shower door are in place when opened;

[0031] A double-door interlock circuit for controlling the opening and closing of the outer door and the inner door of the air shower door to keep the internal space of the air shower door clean; and

[0032] An air shower circuit for controlling the start and stop of the blower of the air shower door.

[0033] As Figure 2 and Figure 3 shown, the switch door circuit includes a controller terminal connected to the RCS system in the warehouse, a fifth intermediate relay KA5, and a sixth intermediate relay KA6. The 5th contact of the fifth intermediate relay KA5 is connected to the 1st contact of the sixth intermediate relay KA6, and light-emitting diodes are provided on both the fifth intermediate relay KA5 and the sixth intermediate relay KA6. Specifically, the opening signal of the RCS system in the warehouse acts on the fifth intermediate relay KA5 and forms a self-lock through the sixth intermediate relay KA6, which is equivalent to the automatic door closer always executing the opening instruction and keeping the door in the normally open state. During the time when the door is normally open, people, goods, etc. can safely pass through the door without the risk of collision. The closing signal output by the RCS system in the warehouse will act on the sixth intermediate relay KA6. After the sixth intermediate relay KA6 acts, the self-lock is released, "COM" and "access control signal" are disconnected, and the door closer can start to execute the closing action.

[0034] As Figure 2 and Figure 4As shown, the door-opening-in-place signal feedback circuit includes a door-opening-in-place position sensor S3. The door-opening-in-place position sensor S3 is connected to the RCS system of the warehouse through the controller terminal. When the door-opening-in-place position sensor S3 detects a metal object, it outputs a low level, indicating that the door is opened in place.

[0035] When the outer door and the inner door of the air shower door are fully opened, the door-opening-in-place position sensor S3 detects metal, and the signal line outputs a low level. Its signal line is connected to the corresponding input port of the terminal hardware, and the low level is valid.

[0036] As Figure 2 and Figure 5 As shown, the double-door interlock circuit includes a first intermediate relay KA1 and an inner door position sensor S1. A light-emitting diode is connected to the inner door position sensor S1. The first intermediate relay KA1 and the inner door position sensor S1 are connected to the RCS system of the warehouse through the controller terminal.

[0037] An inner door position sensor S1 is installed on the inner door. When the door is closed, it detects metal and outputs a high level (12V), driving the first intermediate relay KA1 to act and turning on the outer door opening signal. At this time, if there is an outer door opening signal, the opening action can be normally responded to; if the inner door is opened (such as manually opening the door), the first intermediate relay KA1 does not act. Since the outer door opening signal circuit is connected to the normally open contact of the first intermediate relay KA1, even if the outer door terminal controller issues an outer door opening signal at this time, the door closer cannot respond. Similarly, the inner door position sensor of the outer door controls the inner door opening signal circuit, thus forming an interlock.

[0038] As Figure 2 and Figure 6 As shown, the air shower circuit includes a second intermediate relay KA2, a first time relay KT1, and an outer door position sensor S2. The power supply circuit of the AC contactor P8 of the fan of the air shower door is connected in series with the normally open contact of the second intermediate relay KA2 and the normally closed contact of the first time relay KT1. The second intermediate relay KA2, the first time relay KT1, and the outer door position sensor S2 are respectively connected to the RCS system of the warehouse through the controller terminal.

[0039] When entering the air shower room from the outside, at the moment of closing the door, the outer door position sensor S2 of the outer door drives the second intermediate relay KA2 and the first time relay KT1 (delay-action type). The second intermediate relay KA2 acts immediately, the contactor is energized, and the fan starts to work. After 6 seconds, the first time relay KT1 acts, the normally closed contact is disconnected, the fan stops working, and at the same time, the normally open contact of the first time relay KT1 is closed, and the inner door closer can start to respond to the opening signal.

[0040] Among them, the function of the second intermediate relay KA2 is to ensure that the AC contactor of the fan can only be powered on after the outer door is closed. Otherwise, without the second intermediate relay KA2, as soon as the outer door is opened, the coil of the first time relay KT1 loses power and the fan will start immediately.

[0041] As Figure 2 and Figure 7 shown, the automatic control device for the storage goods shower door further includes a lamp control circuit, and the lamp control circuit includes a seventh intermediate relay KA7, an eighth intermediate relay KA8 and a second time relay KT2. The seventh intermediate relay KA7, the eighth intermediate relay KA8 and the second time relay KT2 are connected in sequence. The normally open contact of the eighth intermediate relay KA8 is connected to the lamp control circuit to control the on and off of the lamp tube. The second time relay KT2 is a power-on delay relay, and the seventh intermediate relay KA7 is driven by a logical OR gate circuit composed of the first intermediate relay KA1 and the second intermediate relay KA2.

[0042] Here, the light is off in the standby state, the light is always on when the inner door or the outer door is opened, and after both the inner and outer doors are closed, the lamp tube turns off automatically after 3 minutes.

[0043] Since the light does not need to be turned on for a long time and only needs to be turned on when there are people or goods passing through the goods shower door, the states sensed by the position sensors installed at the inner and outer doors are used as trigger conditions. At the same time, a set of contacts of the first intermediate relay KA1 and the second intermediate relay KA2 designed in the double-door interlock circuit are used. The normally open contact of the eighth intermediate relay KA8 is connected to the light control circuit to control the on and off of the light. The second time relay KT2 is a power-on delay relay, and the set time is 3 minutes.

[0044] At the moment when the inner door or the outer door is opened, the eighth intermediate relay KA8 is powered on and operates, the light is on, and at the same time, self-locking is formed through a set of normally closed contacts of the second time relay KT2. The light is always on during the door opening period. At the moment of closing the door, the normally open contact of the first intermediate relay KA1 closes, "TIMER_ENABLE" enables the seventh intermediate relay KA7, the second time relay KT2 starts to be powered on, and after 3 minutes, the second time relay KT2 operates, disconnecting the self-locking of the eighth intermediate relay KA8, and the light goes out.

[0045] Here, the first intermediate relay KA1 and the second intermediate relay KA2 form a logical OR gate circuit and can both drive the seventh intermediate relay KA7.

[0046] Through specific design, the eighth intermediate relay KA8 and the second time relay KT2 are in a power-off state in the standby state, extending their service life.

[0047] The structure of the utility model is simple. An automation function can be achieved by adding a controller to the existing air shower door. Compared with the prior art, both the outer door and the inner door of the air shower door can be automatically opened and closed, providing guarantee for the subsequent automatic and safe passage of the AGV car through the air shower door.

[0048] Finally, it should be emphasized that the above are only the preferred embodiments of the utility model, and are not used to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
