Description

Technical Field

[0001] The present invention relates to an air curtain structure, and particularly to an air curtain structure for reducing interference in mechanical operations.

Background Art

[0002] The mechanical equipment required for factory production had to be frequently customized according to the needs of production operations or modified with additional components. For example, after the device was customized or modified separately with additional components, its upper end protruded to obtain an awning structure. Also, when the production conditions of the product required isolation from fine dust and moisture, an air curtain had to be attached to the awning structure.

[0003] However, when an air curtain structure is attached to the awning structure, the mechanical operation space decreases. In mechanical operations, when performing operations such as inserting and picking up or placing on the device, problems may occur where mechanical members easily hit the air curtain structure or the operation becomes difficult, which may lead to production losses and a decrease in production efficiency. Also, even if the air curtain structure is modified to adapt to the awning structure, if the mounting relationship of the component members of the air curtain structure is not properly designed, the modified air curtain structure may easily collide with the operation position of the working machine.

[0007] As shown in Figures 1 to 4, the air curtain structure for reducing interference with machine work provided by the first embodiment of the present invention is assembled in the mounting space 200 of the outwardly projecting canopy structure 201.

[0008] Refer to Figures 1 and 2. The air curtain structure 100 has an air guide device 1 and an air curtain device 2. The air guide device 1 has a body 11 and at least one air guide member 12 installed inside the body 11. The number of air guide members 12 installed can be adjusted according to production requirements. In this embodiment, four air guide members 12 are installed, and the air guide members 12 are fans. The body 11 has at least one intake port 111 for injecting gas, and its bottom surface communicates with at least one connection port 13. The connection port 13 is used as a gas transport path, with one end connected to an air guide member 12 and the other end forming at least one air outlet 131, sending the gas inside the body 11 to the connection port 13 via the air guide member 12, guiding the airflow and causing it to be output from the air outlet 131.

[0009] As shown in Figure 2, the air guide member 12 is ensured to be securely attached to the connection port 13. One end of the connection port 13 has an assembly platform 14, which has a through hole 141 positioned opposite the end opening 132 of the connection port 13. A mounting seat 15 for attaching the air guide member 12 is provided on the assembly platform 14. The assembly platform 14 and the mounting seat 15 enlarge the mounting space at the end of the connection port 13, ensuring that the air guide member 12 is securely assembled on the connection port 13 and stably installed on the connection port 13, thereby ensuring that the airflow is transported stably during operation.

[0010] Next, refer to Figures 2 and 3. The air curtain device 2 has a casing 21 formed by extending along the longitudinal direction and a plurality of air guide spaces 22 formed within the casing 21, and the bottom of the casing 21 has at least one air outlet 23 that communicates with the air guide space 22. In this embodiment, the air outlet 23 is formed along the longitudinal direction of the casing and communicates with the air guide space 22. An assembly tank 212 is formed recessed on the inside of the longitudinal side surface 211 that extends along the longitudinal direction of the casing 21, into which the connection port 13 is fitted and installed, and the inner wall 213 of the assembly tank 212 has at least one air inlet 214 that communicates with the air outlet 131. By installing the connection port 13 inside the assembly tank 212, the length of the air guide device 1 protruding from the casing 21 to the outside is reduced, thereby reducing interference when operating the machine.

[0011] In this embodiment, the connection port 13 has an air outlet 131 formed on one side facing the long side 211, and an air inlet 214 communicating with the air outlet 131 is formed on the inner wall 213 of the assembly tank 212. The air guide member 12 sends the gas injected into the body 11 to the connection port 13, causes it to flow into the air inlet 214 via the air outlet 131, and enters the inside of the casing 21.

[0012] As shown in Figure 3, the casing 21 contains at least one vertical air guide plate 215 and at least one horizontal air guide plate 216. The vertical air guide plate 215 and the horizontal air guide plate 216 each have a plurality of pores (not shown), and the vertical air guide plate 215 and the horizontal air guide plate 216 divide the space inside the casing 21 into a plurality of air guide spaces 22. In this embodiment, the casing 21 is provided with a vertical air guide plate 215 and two horizontal air guide plates 216. The vertical air guide plate 215 and the air inlet 214 are positioned opposite each other, and the internal space of the casing 21 is divided into an air intake space 221, and gas is guided laterally into adjacent air guide spaces 22. Each lateral air guide plate 216 is positioned sequentially at intervals opposite the air outlet 23, dividing the internal space of the casing 21 into two mixing spaces 222, organizing the gas that flows into the air intake space 221, and forming a uniform airflow layer that flows out vertically.

[0013] Refer to Figure 4 as well. When using the air curtain device 2 of this embodiment, the top surface of the casing 21 is fixed to the bottom surface of the canopy structure 201 and placed in the mounting space 200, and the air guide device 1 is installed facing the external machine work space. In order to reduce interference between the air guide device and machine work, the dimensional relationship between the air guide device 1 and the air curtain device 2 and the canopy structure 201 and mounting space 200 will be described in detail below.

[0014] The bottom surface of the shielding structure 201 has an extended length L. A safety distance D for preventing operation interference is provided between the mounting space 200 and the working machine. The casing 21 has two short side surfaces 218 adjacent to the long side surface 211. The short side surface 218 defines the maximum length in the horizontal direction as the casing width W. The connection port 13 has two connection side surfaces 133 that are arranged oppositely and contact the inner wall 213 of the assembly tank 212. The connection side surface 133 defines the length in the horizontal direction as the connection length R. The distance for inserting the connection side surface 133 into the assembly tank 212 is defined as the insertion depth Z. The relational expression among the casing width W, the connection length R, the insertion depth Z, the safety distance D, and the extended length L is: W + R - Z < D + L.

[0015] As can be seen from looking at the above relational expression, when the above relational expression is satisfied, the entire present invention is within the range of the safety distance D, and there is little interference with mechanical operations. When the insertion depth Z is equal to the connection length R, when the connection port 13 is completely inserted into the assembly tank 212, the proportion of the present invention occupying the safety distance D is minimized, and it is possible to effectively reduce the interference of the air guide device with mechanical operations.

[0016] Figs. 5 to 7 show a second embodiment of the air curtain device for reducing interference in mechanical operations according to the present invention. The difference from the above-described first embodiment is that the body 11 communicates with at least one air guide column 16, the air guide column 16 has a hollow shape, one end of the air guide column 16 away from the body 11 is the connection port 13, and at least one air flow outlet 131 is formed. As shown in Fig. 7, the air guide device 1 of the present embodiment increases the distance in the vertical direction between it and the air curtain device 2 through an air guide column 16 having a certain length to accommodate mechanical operations. In other possible embodiments, as shown in Fig. 8, air flow outlets 131 are provided on each connection side surface 133 of the connection port 13, and air flow inlets 214 communicating with the air flow outlets 131 are correspondingly formed on the inner wall 213 of the assembly tank 212. When the air flow introduced into the casing 21 has different flow velocities and flow directions, and the air flows with different flow velocities and flow directions collide with each other, it is convenient for quickly adjusting the flow velocity of the air flow and arranging subsequent discharges for the laminar flow.

[0017] FIG. 9 shows yet another feasible embodiment of the second embodiment, in which the connection port 13 is provided on the long side surface 211 of the casing 21, and at least one air inlet 214 communicating with the air outlet 131 of the connection port 13 is formed on the long side surface 211. At this time, the relational expression among the casing width W, the connection length R, the safety distance D, and the extension length L is W + R ≤ D + L. At this time, the air curtain structure of the present invention effectively gives way to mechanical operations and can reduce mechanical interference.

[0018] FIG. 10 shows a third embodiment of an air curtain device for reducing interference in mechanical operations according to the present invention. The difference from the second embodiment is that two horizontal air guide plates 216 are provided in the casing 21 of this embodiment. Each horizontal air guide plate 216 is arranged opposite to the air ejection port 23 at intervals in sequence, dividing the internal space of the casing 21 into two mixing spaces 222, sorting the gas introduced into the casing 21 by the connection port 13, and forming a uniform air flow layer flowing out in the vertical direction.

[0019] The present invention adjusts the insertion depth of the connection port based on the allowable distance of different machines, installs an elastic member with an air guide flow path between the connection port and the casing, and both ends of the elastic member communicate with the air outlet and the air inlet respectively. The connection port is connected to the casing by a screwing member such as a screw, and the screwing member adjusts the insertion depth of the connection port with respect to the assembly groove, and the size of the concession space can be adjusted based on the operation space required for mechanical operations.

[0020] As can be seen from the above description, the feature of the present invention is that the assembly groove recessed on the side surface of the casing shortens the length by which the air guide device protrudes, reduces the safety distance occupied by the working machine, gives way to a sufficient operation space, reduces the interference in mechanical operations, and can reduce production losses.
