Allowing a worker to put materials into the blanking space 11 through the opening opened by the cover structure 12 under the condition that the blanking space 11 is opened; with the blanking space 11 closed, the blanking box 10 isolates the blanking space 11 from the staff activity area. The main body of the blanking box 10 may be made of a metal material, or may be at least partially made of a relatively strong transparent material (e.g. tempered glass), so as to be convenient for a worker to observe the situation in the blanking space 11. Depending on the actual operating environment, the cover structure 12 may be designed in the form of a sliding door or a hinged flip door.

The isolation device 20 is disposed between the blanking space 11 and the automated production or delivery area, and is used for selectively isolating or communicating the blanking space 11 and the automated production or delivery area. The cover structure 12 is in an open state, and the isolating device 20 cannot communicate the blanking space 11 with the automatic production or conveying area, so that workers are isolated from the automatic production or conveying area in the blanking process; and/or the isolation device 20 is in communication, the limiting cover structure 12 cannot be opened to prevent safety hazards from being created by incorrect operation of personnel.

The above-mentioned unloading safety mechanism is provided with isolating device 20 one side be used for with the production line or transfer chain of mill adjacent, isolating device 20 is used for keeping apart unloading space 11 and automated production or transport region under the isolation state to provide safety protection in the unloading in manual work or other modes, prevent that automated production or transport region's work from influencing the unloading.

Preferably, when the isolation device 20 is in the connected state, the cover structure 12 is defined as unopened by a safety mechanism associated with the isolation device 20; when the cover structure 12 is open, a worker or a gripping device can put or take out material into or from the blanking space 11, at which time the separating apparatus 20 cannot be opened. According to the blanking safety mechanism, workers can be prevented from directly contacting the production or conveying process, the blanking work is finished under the condition of being always isolated from the production or conveying line, and the safety is improved.

In the isolated state of the isolating device 20, the safety lock 14 is used for selectively locking the box 13 and the cover structure 12 in the closed state of the cover structure 12, i.e. whether the safety lock 14 is locked or not can be controlled manually; while in the isolation device 20 connected state, the safety lock 14 remains only in the locked state. The safety lock 14 may be an electromagnet or other automatically controlled mechanical locking device, or may be a manual locking pin or shackle for use with the locking device.

To determine whether the case 13 and the cover structure 12 are accurately closed, at least one of the case 13 and the cover structure 12 is preferably provided with a sensor (a pressure sensor, a proximity switch, or the like) for detecting whether the cover structure 12 and the case 13 are closed; and/or as shown in fig. 1 and 2, the safety lock 14 preferably comprises a first detection unit 15, which first detection unit 15 is adapted to detect whether the safety lock 14 is in a locked state. The sensor or the first detecting unit 15 is associated with (electrically or communicatively connected to) a controller or a driver for controlling the operation of the isolation device 20, so that the isolation device 20 can only communicate when the sensor or the first detecting unit 15 detects that the case 13 and the cover structure 12 are closed or the safety lock 14 is locked, and otherwise the isolation device 20 remains in a closed state. In particular, the isolation device 20 may comprise an isolation door that remains closed in the non-actuated state, which is actuated to open only when the housing 13 is closed with the cover structure 12 or the safety lock 14 is locked, the actuation mechanism or its controller receiving an electrical or communication signal sent by the sensor or the first detection unit 15.

The first detection unit 15 may be part of the safety lock 14, i.e. the safety lock 14 itself has a lock detection function, or the first detection unit 15 may be provided separately in the vicinity of the safety lock 14 to be able to detect. As shown in fig. 2, the safety lock 14 preferably includes a locking pin structure 141 and a locking groove structure 142, one of the case 13 and the cover structure 12 is mounted with the locking pin structure 141, and the other is mounted with the locking groove structure 142 at a position corresponding thereto; the first detecting unit 15 is disposed in the locking groove structure 142 or adjacent to the locking groove structure 142, and is used for detecting whether the locking pin structure 141 is locked with the locking groove structure 142. Preferably, the safety lock 14 may further comprise a locking device 143, the locking device 143 being configured to maintain the safety lock 14 in a locked state in the connected state of the isolation device 20, the locking device 143 being an electromagnet acting on the locking pin structure 141 to energize the electromagnet to attract the locking pin structure 141 into the locking slot structure 142 when locking is required; alternatively, the locking device 143 may be a snap or pin of an automatic switch capable of locking engagement with the locking pin, and in the case where the locking pin structure 141 is inserted into the locking groove structure 142, further mechanical locking with the locking pin structure 141 is formed so as not to be disengaged from the locking groove structure 142.

According to the discharging safety mechanism of the above embodiment, as shown in fig. 1, the isolating device 20 preferably includes a driver 21, an isolating door 22, and a second detecting unit 23. Wherein the driver 21 is fixed relative to the blanking box 10 for driving the isolation door 22 to open or close between the blanking space 11 and the automated production or transport area. The second detecting unit 23 is disposed at a neighboring position of the driver 21 and/or the isolation door 22, and is used for detecting an operation state of the driver 21 and/or detecting a position of the isolation door 22. The second detection unit 23 is preferably electrically or communicatively connected to the locking device 143 described above, and when the second detection unit 23 detects that the actuator 21 and/or the isolation door 22 is in the open state, the isolation device 20 is in the connected state, and the safety lock 14 is only kept in the locked state under the locking of the locking device 143.

Wherein the actuator 21 may be an electric actuator or the actuator 21 may comprise a solenoid valve and a hydraulic or pneumatic actuator controlled by the solenoid valve. The electric drive or solenoid valve is preferably associated (electrically or communicatively connected) with the first detection unit 15 as described above, and is only energized or operable to open the isolation door 22 when the first detection unit 15 detects that the safety lock 14 is locked, as a result of the electric drive or solenoid valve receiving an electrical signal or communication signal from the first detection unit 15. The opening and closing actions of the isolation door 22 may both be controlled by the actuator 21, or preferably the isolation door 22 remains closed in the non-actuated state. In particular, the isolation door 22 may be provided with an elastic member that keeps it closed, or the closing direction of the isolation door 22 is close to or coincident with the direction of gravity. When the driver 21 drives the isolation door 22 to open, the elastic force of the elastic member and/or the gravity of the isolation door 22 need to be overcome, so that even when the driver 21 is powered off or fails, the isolation door 22 can be automatically closed, and the reliability of the isolation door 22 is improved.

According to any of the above embodiments, the present application further provides a manual feeding system, as shown in fig. 3, where the manual feeding system includes the feeding safety mechanism according to any of the foregoing embodiments; and the conveying mechanism 30 is arranged in the blanking space 11, and is used for conveying the materials in the blanking space 11 to an automatic production or conveying area under the communication state of the isolating device. Under the protection of the blanking safety mechanism, when a worker performs blanking through the blanking space 11, the cover structure 12 needs to be opened, and the isolation device 20 is limited in the open state so as not to be communicated with the blanking space 11 and an automatic production or conveying area, so that the blanking working process of the worker is isolated from the production or conveying area. And when the material in the unloading space is transported to the production or the transportation area through the isolation device in the communication state, the cover structure 12 can not be opened, thereby preventing the occurrence of safety risks caused by the misoperation of staff, and realizing the isolation of the staff from the automatic production or the transportation area all the time in the manual unloading process.

According to the manual blanking system, as shown in fig. 3, the conveying mechanism 30 preferably includes a base 31 and a supporting frame 32. The base 31 is fixedly disposed in the blanking space 11, the support frame 32 is slidably mounted on the base 31, at least one bearing position 321 for bearing materials is disposed on the support frame 32, a linear driver for driving the support frame 32 to move is disposed on the base 31, and the linear driver can be an air cylinder, a hydraulic cylinder, an electric cylinder or a motor matched transmission mechanism.

During the manual blanking operation, the worker places the material on the carrying position 321, then closes the cover structure 12 and communicates the isolation device 20, and at this time, the support frame 32 moves toward the automated production or transport area under the action of the linear driver, so that the transport equipment (automatic gripping or lifting mechanism) in the automated production or transport area takes away the material. Preferably, the conveying mechanism 30 further includes a secondary slide 33, the secondary slide 33 being mounted on the base 31 and being slidable between a position close to the isolation device 20 and a position close to the cover structure 12, and the support frame 32 being mounted on the secondary slide 33 and being slidable between a feeding position and a discharging position.

In the blanking position, the bearing position 321 of the support frame 32 is in the projection range of the vertical direction of the secondary sliding table 33, so that the bearing position 321 is close to the cover structure 12, and blanking operation is facilitated. In the feeding position, the carrying position 321 of the supporting frame 32 extends out of the projection range of the secondary sliding table 33 in the vertical direction. The linear drive preferably acts on the secondary slide 33, and the movement between the feed position and the discharge position of the support 32 is preferably controlled manually, further reducing the direct contact of the staff with the automation. Preferably, a positioning member (a buckle, a spring pin, a magnet, or the like) acting on the support 32 is provided at the feeding position and the discharging position of the support 32, respectively, so as to assist the support 32 to maintain at the feeding position or the discharging position. In the case that the worker slides the support frame 32 to the feeding position, the secondary slide table 33 itself does not need to pass through the isolation device 20, and the carrying position 321 of the support frame 32 extending out of the projection range of the secondary slide table 33 in the vertical direction can also pass through the isolation device 20, so that the space occupation range of the conveying mechanism 30 is reduced.

According to the manual blanking system of the preferred embodiment of the present application, the worker is allowed to open the cover structure 12 to perform the blanking operation only when the isolation device 20 is in the closed state. After the material is placed in the bearing position 321 of the supporting frame 32, the worker moves the supporting frame 32 from the discharging position to the feeding position, so that the bearing position 321 is separated from the projection range of the secondary sliding table 33 in the vertical direction, and the projection range is close to the isolation device 20. The cover structure 12 of the blanking box 10 is then closed and the locking pin structure 141 of the safety lock 14 is locked in cooperation with the locking groove structure 142, at which time the first detection unit 15 detects that the locking pin structure 141 enters the locking groove structure 142, thereby allowing the driver 21 of the isolation device 20 to control the isolation door 22 to open, and thereby the blanking space 11 to communicate with the automated production or transport area. After the second detection unit 23 detects that the driver 21 and/or the isolation door 22 are in the open state, the locking device 143 of the safety lock 14 locks the locking pin structure 141 in the locking groove structure 142 to prohibit the cover structure 12 from being opened by a wrong operation. At the same time, the linear driver of the conveying mechanism 30 drives the secondary sliding table 33 to move towards the isolating device 20, and the supporting frame 32 at the feeding position extends the bearing position 321 to an automatic production or conveying area through the opened isolating device 20, so that the blanking process that whole personnel are isolated from equipment for automatic work is realized.

The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solutions of the present application within the scope of the technical concept of the present application, and all the simple modifications belong to the protection scope of the present application.

In addition, the specific features described in the foregoing embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described in detail.

Moreover, any combination of the various embodiments of the present application may be made without departing from the spirit of the present application, which should also be considered as disclosed herein.
