Description

Technical Field

[0001] The utility model belongs to the technical field of sprout auxiliary equipment, in particular to a sprout carrier control system. Background Art

[0002] The sprout processing process includes multiple processes such as washing, frying, and filling. Due to the limited factory area and the rigid requirement that raw and cooked food circulation channels must be processed separately during food processing and production, the sprout processing process is separated upstairs and downstairs. In order to facilitate the transportation of sprouts upstairs and downstairs, a conveyor is set up between the floors. After the processing upstairs is completed, the sprouts are moved to the conveyor and transported downstairs to the later process through the conveyor. Conversely, the conveyor is transported upstairs.

[0003] The conveyor is a transport box that can move up and down, and the transport box is always in an open state. There are start switches on the upper and lower floors respectively. By operating the start switches on the upper or lower floors, the conveyor can be controlled to move upward or downward. However, since workers are not clear about the loading status of the other floor when loading sprouts, there is a great safety hazard: when the workers upstairs are loading, the workers downstairs may easily start the conveyor without knowing it. If the workers stand between the transport box and the platform at this time, the sudden movement of the transport box will be dangerous. Utility Model Content

[0004] In view of the above problems existing in the prior art, the utility model provides a sprout carrier control system, which indicates the loading status of the carrier through an indicator light to avoid starting the loader during the loading process.

[0016] like Figure 1 The sprout carrier control system shown includes a first inverting rod 3, a first proximity switch, a second proximity switch, a first indicator light, a second indicator light and a PLC controller.

[0017] Platforms are provided for carriers on the upper and lower floors of the factory. The platforms are provided corresponding to the transport boxes 11, and the transport boxes 11 can be loaded and unloaded on the platforms. Transport passages are provided outside the platforms. An upper gate 2 is installed in the upper passage 1 leading to the upper platform. The upper gate 2 is a side sliding door. The right side of the upper gate 2 is installed on the right wall of the upper passage 1. When the upper gate 2 is pulled outward, the upper passage 1 is opened. When the upper gate 2 is pushed outward and inward, the upper passage 1 is closed and locked by the locking device on the left wall of the upper passage 1. A first inverted rod 3 is installed on the left side of the upper gate 2. A first proximity switch transmitter 5 is installed in the middle of the first inverted rod 3, and a first proximity switch receiving head 4 corresponding to the first proximity switch transmitter 5 is installed on the left wall of the upper passage 1.

[0018] A lower gate 7 is installed in the lower passage 6 leading to the lower platform. The lower gate 7 is a side sliding door. The right side of the upper gate 2 is installed on the right wall of the lower passage 6. When the lower gate 7 is pulled outward, the lower passage 6 is opened. When the lower gate 7 is pushed inward, the lower passage 6 is closed and locked by a locking device on the left wall of the lower passage 6. A second inverted rod 8 is installed on the left side of the lower gate 7. A second proximity switch transmitter 10 is installed in the middle of the second inverted rod 8, and a second proximity switch receiving head 9 corresponding to the second proximity switch transmitter 10 is installed on the left wall of the lower passage 6.

[0019] The first proximity switch transmitter 5, the first proximity switch receiver 4, the second proximity switch transmitter 10 and the second proximity switch receiver 9 are connected to the PLC controller, and the PLC controller is used to receive the proximity switch signal. The PLC controller is also connected to two indicator lights, the No. 1 indicator light within the visible range of the carrier start switch on the upper layer and the No. 2 indicator light within the visible range of the carrier start switch installed on the lower layer. After all the sprouts to be transported are moved to the platform, the staff observes the lighting of the indicator lights and determines whether to start the loader to make the transport box 11 reach the corresponding floor based on the indicator lights.

[0020] When the upper channel 1 is not in operation, the upper gate 1 closes the upper channel 1, and the first proximity switch transmitter 5 on the first inverted rod 3 contacts the first proximity switch receiver 4 to generate a signal; when the staff enters the upper channel 1, the upper gate 2 is pulled open, and the first inverted rod 3 rotates outward with the gate, and the first proximity switch transmitter 5 on the first inverted rod 3 is disconnected from the first proximity switch receiver 4, and the first proximity switch has no signal transmitted to the PLC controller. When the staff performs loading or unloading operations, the upper channel 1 is continuously opened, and the whole process is in a no-signal state. When the staff enters the lower channel 6, the lower gate 7 is pulled open, and the second inverted rod 8 rotates with the gate, and the second proximity switch transmitter 10 on the second inverted rod 8 is disconnected from the second proximity switch receiver 9, and the second proximity switch has no signal transmitted to the PLC controller. When the staff performs loading or unloading operations, the lower channel 6 is continuously opened, and the whole process is in a no-signal state.

[0021] The PLC controller receives the signals from the first proximity switch and the second proximity switch and feeds back through the indicator light. When there is no signal from both proximity switches, it means that the channels on both floors are in the open state and are in operation. At this time, the red light is on and the carrier is prohibited from being started. When only one proximity switch has a signal, it means that the channel on the other floor is in the closed state and there is no loading operation. At this time, the green light is on and the transportation operation can be started.

[0022] The staff is located in the lower channel 6. After opening the lower channel 6 and moving the sprouts to the lower platform, he observes the indicator light. If the indicator light is green, it means that there is no loading operation on the other floor and the carrier can be started. At this time, the transport box 11 moves downward to the lower platform, and the sprouts are moved to the transport box 11 and then transported to the upper platform to complete the transportation operation; the indicator light is red, indicating that the upper channel 1 is open and loading operations are in progress, and the carrier cannot be started.

[0023] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
