Description

Technical Field

[0001] The present invention relates to a refrigeration control technology, and particularly to an industrial chiller controller. Background Art

[0002] The cold storage system is a very commonly used refrigerated storage technology in modern industrial and commercial applications. A cold storage is a storage device that can maintain a constant temperature and humidity, which is particularly important for the short-term and long-term storage of items such as food, liquids, chemicals, medicines, and vaccines, and is more closely related to people's daily commercial activities and life. The industrial chiller is mainly used for the refrigeration function of the cold storage. Nowadays, people's requirements for the refrigeration effect of the cold storage are getting higher and higher, which is also because the temperature sensitivity of the stored items is getting higher. In places where goods are transported, temporarily stored, and long-term stored, if better storage effects can be achieved, it is an essential element for future cold storages to meet the needs of goods. In the use of cold storages, generally, before the goods are transported to the front of the cold storage, the operator directly opens the cold storage door, places the goods inside the cold storage, and then closes the cold storage door for refrigeration. During this process, the temperature of the goods entering the cold storage is very likely to be higher than the temperature inside the cold storage. Sometimes, there is a large temperature difference between the temperature of the goods just sent into the cold storage and the temperature inside the cold storage. During long-term use, especially for goods that are sensitive to temperature inside the cold storage, the quality of the goods may be reduced due to the influence of the temperature of the newly entered goods. Cold storages vary in size. When storing goods, in order to avoid the temperature influence during the goods-in process, the goods are first placed at a position separated from other goods inside the cold storage by a certain distance, which greatly reduces the space utilization rate of the cold storage; in order to reduce space waste, the goods are moved to a stacking position closer to other goods after the temperature of the entered goods reaches the overall temperature level of the cold storage. Although it can achieve the purpose of saving space and storing more goods, it wastes more manpower and material resources and greatly reduces the refrigerated storage efficiency of the cold storage. Summary of the Invention

[0003] The technical problem solved by the present invention is to provide an industrial chiller controller, which can effectively improve the temperature synchronization of goods by separating and stacking them first after entering the cold storage, and then automatically centrally stack the goods, improving the refrigeration effectiveness of cold storage goods and the stacking efficiency of cold storage goods.

[0031] In a preferred embodiment of an industrial chiller controller of the present invention, please refer to Figures 1 to 3As shown in the figure, the industrial chiller controller of the present invention is provided with an input module, a data acquisition module, a main control module and a relocation control module; the input module includes a parameter input component and a parameter display component; the data acquisition module is signal-connected to sensors arranged in the cold storage to acquire parameters inside the cold storage; the main control module receives the data signals of the data acquisition module and the input module, analyzes and processes the data signals, and outputs control signals; the control signals include a cold storage total control signal and a relocation control signal; the cold storage total control signal is mainly used to adjust the cold air output of the cold storage to stably control the refrigeration temperature of the cold storage.

[0032] The relocation control module receives the relocation control signal to control the action of the relocation supporting components arranged in the cold storage; the relocation supporting components include a support frame 1 arranged at the bottom of the cold storage, and the bottom support frame 1 is a grid frame structure with grids of a set size, and the set size can be determined according to the specific use of the cold storage. Generally, the size of the grid should be smaller than and close to the area size when the goods are stacked, so as to control the goods stacked above to have a certain angle of inclination for movement. At the bottom of each grid, a support rotating disk 2 is fixedly arranged, and at least three jacking devices 3 are evenly distributed on the periphery of the support rotating disk 2. A movable rolling ball 6 is arranged at the top of the jacking device 3, and a rolling support wheel 7 is arranged at the bottom thereof to rotate around the support rotating disk 2 and support the jacking device 3; a rotation driver is arranged in the middle of the support rotating disk 2, and the jacking device 3 is connected to an external pressure source; the external pressure source is used to drive the jacking device 3 to rise or fall by a specified height; the rotation driver and the external pressure source are signal-connected to the relocation control module; preferably, the external pressure source can control each jacking device 3 respectively through a plurality of control valves. Through the power input of the external pressure source, each jacking device 3 can realize the control of rising and falling, so that the goods supported by the top of the jacking device 3 can be jacked up or put down.

[0033] The relocation supporting components include a supporting plate 5 for supporting goods, and the size of the supporting plate 5 is larger than twice the grid size; the bottom of the supporting plate 5 is a smooth plane for contacting the top of the support frame 1 or the rolling ball 6; preferably, the goods can be stacked as much as possible according to the set area by using the supporting plate 5 and then sent into the cold storage. After being sent into the cold storage, with a proportion of about twice the area of the grid, it can better ensure that the supporting plate 5 can be transported between multiple grids and finally reach the edge position.

[0034] A stock-in monitoring sensor is provided inside the support frame 1. The data acquisition module is signal-connected to the stock-in monitoring sensor. The stock-in monitoring sensor monitors the temperature of the goods newly delivered into the cold storage. Preferably, the stock-in monitoring sensor can be a temperature monitor respectively arranged under each grid, or an infrared imaging temperature monitor, etc., which can accurately obtain the temperature state of the incoming goods. More preferably, it is a stock-in monitoring sensor that can obtain the current position of the goods. When the temperature of the goods has not dropped to the cold storage temperature, the main control module sends a non-action shifting control signal to the shifting control module; when the temperature of the goods drops to the cold storage temperature, the main control module sends a shifting control signal for a shifting action to the shifting control module. The shifting control module controls the external pressure source and the support rotating disc 2 located under the supporting plate 5 of the goods to act according to the shifting control signal. The support rotating disc 2 rotates to a specified angle. At this time, the support rotating disc 2 forms an inclined plane in cooperation with the already moving jacking device 3 according to the direction in which the goods need to move. For example, when the jacking device 3 is located on the side opposite to the moving direction of the goods, the height of the previously jacked-up jacking device 3 adjacent to it is higher than that of the current jacking device 3 until the highest height; and for the jacking device 3 located in front of the moving direction, it gradually jacks up until the rear side of the goods moves to the current position. Therefore, of course, if the jacking device 3 rises to a specified height according to the shifting direction of the goods, the rolling beads 6 on the top of the jacking device 3 jack up the bottom of the supporting plate 5. The supporting plate 5 slides obliquely in the specified direction under the support of the plane formed by the plurality of rolling beads 6. Thus, through the jacking linkage action of the support rotating discs 2 of multiple grids, the goods can finally be moved to the centralized stacking position.

[0035] In the preferred embodiment of the industrial chiller controller of the present invention as described above, pressure sensors are provided on each of the grids of the support frame 1 to form a pressure sensing grid structure. Preferably, pressure sensors are provided on the support frame 1. By detecting the pressure states at various positions on the support frame 1, the positions and weights of the goods that have been stacked and have not yet performed the shifting action can be obtained. Thereby, the main control module can send a more accurate shifting control signal based on the above position information.

[0036] In the preferred embodiment of the industrial chiller controller of the present invention as described above, when the jacking device 3 acts, the shifting control signal includes a control instruction for controlling the external pressure source to perform a vibration action control every time the jacking device 3 rises by a set height. Preferably, during the jacking process of the jacking device 3 of the present invention, the control of the vibration of the jacking device 3 is also carried out to ensure that the supporting plate 5 can slide more timely and accurately in the inclined direction.

[0037] In the preferred embodiment of the industrial chiller controller of the present invention as described above, contact sensors are provided on the outer periphery of the support plate 5, each of the contact sensors is provided with direction and sequence coding, the contact sensors are connected to the data acquisition module signals, and the main control module outputs the goods storage map according to the contact signals of the contact sensors and the signals of the pressure sensors. Preferably, by providing contact sensors on the support plate 5, and setting the direction and sequence coding for each periphery, so that each support plate 5 touches each other after being moved, and obtains contact signals, which are sent to the data acquisition module, so that the direction and position information of the goods that have been stacked in place can be effectively obtained. Furthermore, a gyroscope device can be provided on the support plate 5 to better know the direction and position of the support plate 5.

[0038] In the preferred embodiment of the industrial chiller controller of the present invention as described above, when the goods storage diagram shows that there are goods that are spaced from other goods by a distance greater than a fixed distance, the main control module sends a total control signal for the cold storage, including increasing the cold air output by a set value, and gradually reducing the cold air output at a set reduction rate until the cold storage returns to the original set cold air output value. In this way, the present invention can effectively determine whether there are goods in the cold storage that need to be temperature assimilated in addition to the judgment signal of the temperature sensor, thereby achieving a double insurance judgment effect.

[0039] In a preferred embodiment of the industrial chiller controller of the present invention as described above, a plurality of cold air nozzles are provided on the top of the cold storage, and the cold air nozzles are connected to the main control module by signal; according to the position of the goods storage diagram, the main control module controls the opening of the designated cold air nozzles to spray cold air toward the goods newly entering the cold storage until the temperature of the goods is consistent with the temperature of the cold storage.

[0040] In the preferred embodiment of the industrial chiller controller of the present invention as described above, the peripheral edge of the supporting plate 5 is provided with an arc-shaped edge that bends upward. Preferably, the peripheral edge of the supporting plate 5 is provided with an arc-shaped edge that bends upward, which can prevent the edge of the inclined supporting plate 5 from hitting and getting stuck with the edge of the grid after moving.

[0041] In a preferred embodiment of the industrial chiller controller of the present invention as described above, a distance detector 4 is provided outside one side of the lifting device close to the center of the supporting rotating disk 2, and the distance detector 4 is signal-connected to the data acquisition module. After the main control module sends an instruction for the lifting device 3 to perform a lifting action, when the distance value detected by the distance detector 4 is greater than a shielding distance value, the lifting action of the lifting device 3 is suspended until the distance detected by the distance detector 4 is vertically equal to the shielding distance value, and then the lifting action instruction of the lifting device 3 is executed. The distance detector 4 is mainly used to detect whether the supporting plate 5 has reached above the lifting device 3. If it has reached, the lifting action instruction of the lifting mechanism can be executed. Thus, accurate protection of the lifting operation is achieved, and it is further ensured that the supporting plate 5 can move the goods to the designated position with the goods.

[0042] The industrial chiller controller of the present invention is different from general conventional chiller controllers. It is configured with a displacement supporting component, which is used to prevent the newly incoming goods from being directly pushed against the corners or being close to other already entered goods after the newly incoming goods enter the cold storage. Instead, the handling personnel can directly place the goods into the cold storage, and there is a certain distance between the goods and other goods stacked on the edge, so that the newly incoming goods can be quickly cooled to the set temperature of the cold storage. At the same time, it also avoids the temperature of the newly incoming goods from affecting the refrigeration effect of the goods already stored in the cold storage, and avoids the problem of deterioration of product quality. Further, when the temperature of the goods is assimilated to the temperature of the cold storage, through the control and position adjustment and movement functions of the displacement control module and the displacement supporting component of the industrial chiller controller of the present invention, the goods that have completed temperature assimilation can be automatically moved closer to the corners or next to other goods that have been stacked in place, and finally centralized stacking is completed. The present invention can better assist the newly incoming goods in temperature assimilation, protect the quality of the goods, and at the same time reduce the operation of manually stacking the goods again, making the storage space in the cold storage utilized most efficiently.
