Description

Technical Field

[0001] This utility model belongs to the technical field of degumming machines, and specifically relates to a manual discharge safety system for degumming machines. Background Technology

[0002] The feeding and discharging actions of the degumming machine's discharge trolley are entirely controlled by the air source that drives the cylinder, which is switched by a manual air exchange valve. During the process of the robotic arm placing the basket and the trolley moving, the trolley's feeding and discharging actions are manually controlled by the operator. Sometimes, if the operator chooses the wrong time, it can cause interference between the robotic arm's lifting and lowering actions and the trolley's feeding and discharging actions, resulting in mechanical accidents and serious damage to the crystal rod products.

[0003] Therefore, it is necessary to completely avoid the trolley entering and exiting during the basket-laying operation of the robotic arm, and to prevent employee operation from interfering with the mechanical operation of the equipment, which could lead to collision accidents. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a manual discharge safety system for degumming machines. The specific technical solution is as follows: The manual discharge safety system for the degumming machine includes: A material receiving and transferring device is used for reciprocating motion between the infeed position and the discharge position; A drive device, the output of which is connected to the material receiving and transferring device, is used to drive the material receiving and transferring device to reciprocate between the infeed position and the discharge position. A material loading device is installed above the infeed position and is used to load materials into the material receiving and transfer device; A detection device is used to detect whether the material loading device is in a descending state and generate a detection signal; A gas supply channel has an external gas source connected to its input end and a drive device connected to its output end to form a gas supply. The gas path on / off controller is installed on the gas supply channel and communicates with the detection device. It is used to switch the on / off state according to the detection signal of the detection device. When the detection device detects that the material loading device is descending, the gas path on / off controller is closed to cut off the gas supply to the drive device. When the detection device detects that the material loading device is rising to a designated position, the gas path on / off controller is opened to restore the gas supply.

[0005] As a further technical solution of this utility model, the driving device includes a first air passage interface and a second air passage interface, wherein when air enters through the first air passage interface, the driving device performs a return stroke to transfer the material receiving and transferring device from the discharge position to the inlet position, and when air enters through the second air passage interface, the driving device performs a stroke stroke to transfer the material receiving and transferring device from the inlet position to the discharge position.

[0006] As a further technical solution of this utility model, the detection device is a pressure sensor, which is set between the top of the material loading device and the mounting surface. When the material loading device rises to a designated position, it presses the pressure sensor to generate an opening signal, and when the material loading device descends, it releases the pressure to generate a closing signal.

[0007] As a further technical solution of this utility model, the detection device is a photoelectric sensor, which is set on the same plane as the material loading device. When the material loading device rises to a designated position, it blocks the light signal to generate an open signal, and when the material loading device descends, it releases the light signal to generate a close signal.

[0008] As a further technical solution of this utility model, it also includes a gas path switching valve, which is installed on the gas supply channel and connected in series between the gas path on / off controller and the drive device. The gas path switching valve has two outlets, which are respectively connected to the first gas path interface and the second gas path interface of the drive device, and are used to controllably switch the gas path to select the stroke or return action of the drive device.

[0009] As a further technical solution of this utility model, the air path switching valve is a manually operated valve or an electromagnetically driven valve, which controls the stroke and return actions of the drive device by switching the air path direction.

[0010] The beneficial effects of this utility model are as follows: In this application, the position status of the material loading device is monitored in real time by a detection device. Combined with the rapid response of the air circuit on / off controller, the air supply of the drive device is immediately cut off when the material loading device is detected to be descending, which effectively avoids the risk of mechanical interference between the material receiving and transfer device and the material loading device.

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0014] Figure 1 A schematic diagram of the overall structure of the manual discharge safety system for the degumming machine is shown. Figure 1The manual discharge safety system of the degumming machine includes a material receiving and transferring device 100, a drive device 200, and a material loading device 300. The material receiving and transferring device 100 receives material and can transfer the received material to the outside. Specifically, the material receiving and transferring device 100 reciprocates between the infeed position and the discharge position. In an empty state, it reaches the infeed position to receive material, and in a fully loaded state, it moves from the infeed position to the discharge position. The output end of the drive device 200 is connected to the material receiving and transferring device 100 and is used to drive the material receiving and transferring device 100 to reciprocate between the infeed position and the discharge position. The drive device 200 has a first air passage interface 210 and a second air passage interface 220. That is, when… When air enters through the first air inlet 210, the drive device 200 performs a return stroke, transferring the material receiving and transferring device 100 from the discharge position to the inlet position. When air enters through the second air inlet 220, the drive device 200 performs a stroke stroke, transferring the material receiving and transferring device 100 from the inlet position to the discharge position. The material loading device 300 is located above the inlet position of the material receiving and transferring device 100 and is used to load material into the material receiving and transferring device 100. That is, when the material receiving and transferring device 100 reaches the inlet position in an empty state, the material loading device 300 lowers and places the material into the material receiving and transferring device 100 for loading. The drive device 200 is a drive cylinder.

[0015] It should be noted that the above are all the working processes of degumming machines in the existing technology.

[0016] See also Figure 1 The manual discharge safety system of the degumming machine also includes a detection device 400, a gas supply channel 500, and a gas path on / off controller 600. The detection device 400 is used to detect whether the material loading device 300 has fallen and to send a detection message. The input end of the gas supply channel 500 is connected to an external gas source, and the output end is connected to the drive device 200. The gas path on / off controller 600 is installed on the gas supply channel 500 and is communicatively connected to the detection device 400. The gas path on / off controller 600 can receive the detection message sent by the detection device 400 to switch between open and closed states. The gas path on / off controller 600 can be one of a solenoid valve, a solenoid directional valve, or a speed regulating throttle valve.

[0017] There are two types of detection information: if the material loading device 300 has already fallen, a shut-off signal is issued; if the material loading device 300 has not yet fallen, an open signal is issued. Both shut-off and open signals are electrical signals.

[0018] The gas path on / off controller 600 has an on state and a off state to respond to the on and off signals issued by the detection device 400, respectively. That is, when the detection device 400 detects that the material loading device 300 has moved down, it issues a off signal. At this time, the gas path on / off controller 600 receives the off signal from the detection device 400 and enters the off state, cutting off the gas supply to the drive device 200 and forcing the drive device 200 to shut down, thereby avoiding interference between the material receiving and transferring device 100 and the material loading device 300. When the detection device 400 detects that the material loading device 300 has risen to a designated position, it issues an on signal. At this time, the gas path on / off controller 600 receives the on signal from the detection device 400 and enters the on state, restoring the gas supply to the drive device 200. At this time, the drive device 200 can drive the material receiving and transferring device 100 to move again.

[0019] In one embodiment, the detection device 400 is a pressure sensor disposed between the top of the material loading device 300 and the mounting surface; when the material loading device 300 rises to a designated position, the material loading device 300 presses the detection device 400 to generate a pressure signal and sends an opening signal; when the material loading device 300 moves down, the pressure state of the material loading device 300 on the detection device 400 changes and sends a closing signal.

[0020] In another embodiment, the detection device 400 is a photoelectric sensor disposed on the same plane as the material loading device 300; when the material loading device 300 rises to a designated position, the material loading device 300 blocks the light signal emitted by the detection device 400 and sends an open signal; when the material loading device 300 moves down, the material loading device 300 releases the light signal emitted by the detection device 400 and sends an close signal.

[0021] See also Figure 1 The manual discharge safety system of the degumming machine also includes a gas path switching valve 700. The gas path switching valve 700 is installed on the gas supply channel 500 and connected in series between the gas path on / off controller 600 and the drive device 200. The gas path switching valve 700 has two outlets corresponding to the first gas path interface 210 and the second gas path interface 220, respectively. The gas path switching valve 700 is driven to switch the gas path between the two outlets. That is, the inlet of the gas path switching valve 700 is connected to the outlet of the gas path on / off controller 600, and the two outlets of the gas path switching valve 700 are connected to the first gas path interface 210 and the second gas path interface 220, respectively. When the gas path switching valve 700 is driven, the gas can be switched between the two outlets of the gas path switching valve 700 to correspond to the stroke and return actions of the drive device 200.

[0022] The pneumatic switching valve 700 is either a manually operated valve or a solenoid-driven valve.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
