Description

Technical Field

[0001] This invention relates to the field of door opening technology devices, and more specifically, to a two-way flip-type door opening machine and its usage method. Background Technology

[0002] A door opener is a mechanical device used in modern society to replace manual door opening. It typically includes a geared motor as the power source and a limiting structure for the door opening track. There are many different ways to classify door openers, and the flip-type door opener, as a type of door opener, also includes a flip-type door body in addition to the standard configuration of a door opener, which allows the door body to rotate as the door opener operates.

[0003] Current flip-type gate openers can only move and rotate along the direction of the gate under the guidance of the power source. Moreover, the gate usually moves from bottom to top in a direction away from the ground. This makes the size and shape of the opening area fixed. When an object exceeds the height allowed after the gate is opened, the object will not be able to pass through the gate area.

[0004] In actual production applications, the height and width of objects that need to pass through a gate are generally not measured precisely. Instead, operators often estimate and judge based on experience, arriving at a conclusion that the object should be able to pass. In fact, this experience-based judgment is indeed effective, and operators can often filter out most objects that are obviously impossible to pass through. However, when actually passing through the gate, the height and width of some objects fall within the error range of the experience-based judgment. This requires rearranging the objects or using other more labor-intensive and resource-intensive methods to get them through the gate, affecting work efficiency and increasing transportation costs. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a two-way flip-type door opener and its usage method.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a two-way flip-plate door opener, comprising a door body, a power source, and a signal component mounted on a wall. The door body includes a plurality of flip plates, adjacent flip plates being rotatably connected to each other. Two mutually perpendicular active channels are provided at one corner of the top surface of the door body. The plane where the extension trajectory of any active channel lies is perpendicular to the cross-section with the largest area of ​​the door body. A metal active slider is fixedly connected to the door body. The metal active slider is slidably connected within any active channel. The power source is located between the two active channels. The power source is driven by two linkage assemblies. An electromagnet is provided on the side of the linkage assembly away from the power source. The signal component controls the electromagnet to be energized and the power source to be energized. The electromagnet abuts against the metal active slider.

[0007] By adopting the above technical solution, the gate can obtain two selectable directions of movement, the flap can obtain two rotation modes to adapt to the selected direction of movement of the gate, and the area that the gate can pass through changes with the direction of movement of the gate. Through the mutual compensation of height and width, it can adapt to the objects that need to pass through. This improves the accuracy of operators in estimating the obtained allowable passage range, thereby improving work efficiency and transportation efficiency, and reducing additional manpower and financial consumption.

[0008] The present invention is further configured such that the rotation axis of the adjacent flaps is located on the side closer to the active channel.

[0009] By adopting the above technical solution, when the door panel moves to the top, the mutual compression and support between adjacent flaps stabilizes the flap state.

[0010] The invention is further configured such that: each of the four sides of the flap is provided with an installation groove, a fixed column is fixedly connected in the installation groove, the installation grooves of adjacent flaps are connected, a connecting column is provided between the fixed columns in adjacent installation grooves, and the fixed column and the connecting column are rotatably connected.

[0011] By adopting the above technical solution, the rotation between adjacent flaps is achieved through the rotational connection of the fixed column and connecting column in the installation groove. The embedded rotation hides the rotation area inside, protecting the rotation-related components, while ensuring that the rotation in two directions does not interfere with each other.

[0012] The present invention is further configured such that: the active channel includes a slightly curved channel near the door panel and a straight channel away from the door panel; when the door panel is in the closed state, the metal active slider is located outside the entrance of the active channel.

[0013] By adopting the above technical solution, the metal active slider will not be affected by the other active channel when it moves towards one active channel.

[0014] The invention is further configured such that: a connector is fixedly connected to the metal active slider near the door body; the metal active slider is fixedly connected to the door body through the connector; the active channel has a through groove 1 and a through groove 2 respectively opened on the symmetrical wall surface; the extension trajectory of the through groove 1 and the through groove 2 is the same as the extension trajectory of the active channel; the connector is slidably connected to the through groove 1; and the connecting rod assembly is slidably connected to the through groove 2.

[0015] By adopting the above technical solutions, the cooperation between connector one and through groove one, the cooperation between slider and active channel, and the cooperation between linkage assembly and through groove two ensure the correctness and stability of the door panel's movement direction.

[0016] The present invention is further configured to include at least two driven channels with the same shape as the straight channel and at least two driven sliders. At least one driven slider is fixedly connected to the top surface and the side surface of the door panel, and the driven slider is slidably connected in the driven track. The driven channel is parallel to the active channel, and at least one driven channel parallel to the active channel is provided for each active channel.

[0017] By adopting the above technical solution, the cooperation between the driven channel and the driven slider assists the cooperation between the active channel and the metal active slider, making the movement of the door panel smoother and more stable, and providing support for the door panel.

[0018] The invention is further configured such that: an installation plate is fixedly connected between the outer walls of the two active channels; the power source is fixedly connected to the end of the slide plate away from the door panel; two limiting grooves are provided on the installation plate; and the connecting rod assembly is slidably connected to the limiting grooves.

[0019] By adopting the above technical solution, the power source and supporting linkage assembly are fixed by the mounting plate, while the linkage assembly moves smoothly with the power source.

[0020] The present invention is further configured such that: the metal active slider is cylindrical, and the contact point between the electromagnet and the metal active slider is claw-shaped and conforms to the curved surface of the metal active slider.

[0021] By adopting the above technical solution, the contact area between the electromagnet and the slider is increased, thereby increasing the force on the slider.

[0022] The invention is further configured to include a magnet block, which is disposed on a wall away from the active channel, and the magnet block and the flap are on the same plane perpendicular to the ground, and the flap is made of metal.

[0023] By adopting the above technical solution, the magnet block can fix the door panel when it is closed.

[0024] This invention also provides a method for using a two-way flip-type door opener, the specific steps of which are as follows:

[0025] Step 1: The operator judges the size and shape of the object that will pass through the area where the door panel is located, and sends the corresponding door opening signal to the signal component through a conventional signal transmitting device;

[0026] Step 2: When the signal component receives the door opening signal, it selects the appropriate electromagnet to be energized according to the door opening signal, and at the same time starts the power source;

[0027] Step 3: The electromagnet attracts the metal active slider, and the power source drives the linkage assembly to slide. The flap slides in the direction of the working electromagnet as the power source rotates, and at the same time, the adjacent flaps rotate to adapt to the movement trajectory.

[0028] Step 4: When an object passes through the area where the door panel is located, the operator sends a closing signal to this embodiment. When the signal component receives the closing signal, the power source reverses its rotation to drive the flap to slide and rotate, so that the door panel is reset. Finally, the electromagnet is de-energized, completing one door opening and closing cycle. If the object cannot pass through the area where the door panel is located, proceed to step 5.

[0029] Step 5: Repeat steps 1 to 4, this time changing the door opening direction in step 1.

[0030] By adopting the above technical solution, the entire process does not require any professional knowledge and can be used by ordinary operators. Through the operator's initial judgment of the objects, a batch of objects that are obviously impossible to pass through the area where the door is located are filtered out. For the remaining objects that can pass through the area where the door is located based on experience, the door's allowable passage area is changed by moving and rotating the flap in different directions, thereby adaptively increasing the range of the door's allowable passage area.

[0031] In summary, the present invention has the following beneficial effects:

[0032] The present invention discloses a bidirectional flip-type door opener and its method of use. By changing the area of ​​the allowable passage zone of the door, the possibility of objects that could pass through the door after the operator's initial visual inspection and screening experience is further increased. This is achieved by the rotational connection between the flip plates and the attraction of the slider by an electromagnet. The operator only needs to send corresponding signals to control it. Therefore, the present invention has better adaptability to the shape of the passing object, and the way to change the opening direction is simple and easy, saving manpower, material resources and financial resources.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example

[0045] A type of two-way flip-up door opener, such as Figure 1As shown, the device includes a square door 11, a power source, and a signal component 13 mounted on the wall. The door 11 comprises nine flaps 14, each with a square cross-section. These nine flaps 14 are arranged in a square array, with adjacent flaps 14 rotatably connected to each other. Two mutually perpendicular active channels 15 are located at one corner of the top surface of the door 11. The plane containing the extension trajectory of any active channel 15 is perpendicular to the cross-section with the largest area of ​​the door 11. A metal active slider 16 is fixedly connected to the door 11 and slidably connected within any active channel 15. The power source is a geared motor 12, which is positioned between the two active channels 15. The geared motor 12 is connected to two linkage assemblies. An electromagnet 17 is located on the side of the linkage assembly away from the power source. The signal component 13 controls the on / off state of the electromagnet 17 and the power source. The electromagnet 17 is connected to the metal active slider 16. When the sliding block 16 abuts, and a person or object wants to pass through the door 11 and sends a signal to the signal component 13, the signal component 13 energizes an electromagnet 17 and a geared motor 12 according to the signal. The signal component 13 includes an infrared signal sensor and a PLC controller. External operators send two different infrared signals to the signal component 13. When the first infrared signal is sent, the infrared signal sensor and the PLC controller read the signal and control the geared motor 12 to start, while energizing one of the electromagnets 17. When the second infrared signal is sent, the infrared signal sensor and the PLC controller read the signal and control the geared motor 12 to start, while energizing the other electromagnet 17. The geared motor 12 outputs power, driving the flap 14 to move along one of the two active channels 15 and causing the flaps 14 to rotate relative to each other to adapt to the shape of the active channel 15, thereby opening the door 11.

[0046] like Figure 2 and Figure 3 As shown, the rotation axis of adjacent flaps 14 is located on the side closer to the active channel 15. Therefore, when the door 11 moves to the top, the rotational connection on only one side between the flaps 14 ensures that the door 11 will not deform due to the movable flaps 14. The flaps 14 can rotate in one direction, either horizontally or vertically. The angle between two adjacent flaps 14 is 115° to 180°. Each of the four sides of the flap 14 on the side closer to the active channel 15 has a mounting groove 18. The mounting groove 18 is square and passes through two adjacent surfaces of the flap 14. A fixing post 19 is fixedly connected in the groove 18. The mounting grooves 18 of adjacent flaps 14 are connected. A connecting post 20 is provided between the fixing posts 19 in adjacent mounting grooves 18. The fixing post 19 and the connecting post 20 are rotatably connected. The fixing post 19 is fitted with and rotatably connected to two elliptical rotating rings 40. The rotating rings 40 have two through holes on the surface with the largest area. The fixing post 19 is rotatably connected to one through hole, and the connecting post 20 is rotatably connected to the rotating ring 40 in the other through hole. Locking elements 41 are also provided at both ends of the connecting post 20 to prevent the connecting post 20 from falling off.

[0047] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the active channel 15 is fixedly connected to the wall where this embodiment is installed. The active channel 15 includes a slightly curved channel 21 near the door 11 and a straight channel 22 away from the door 11. The angle of the slightly curved channel 21 is 90°. When the door 11 is closed, the metal active slider 16 is outside the entrance of the active channel 15. At this time, the metal active slider 16 abuts against the slightly curved channel 21, so that the metal active slider 16 will not be blocked or affected by the other active channel 15 when sliding towards one active channel 15, thereby ensuring the stability of the movement stroke of the door 11 and the flap 14. A connector 25 is fixedly connected to the side of the metal active slider 16 near the door 11. The connector 25 is cylindrical in shape, and its two circular surfaces are respectively connected to the door 11 and the metal active slider 16. The active slider 16 is fixedly connected. The two closest surfaces of the connecting piece 25 and the contacting flap 14 are at 135°. The metal active slider 16 is fixedly connected to the door body 11 through the connecting piece 25. The active channel 15 has through slots 23 and 24 respectively on the symmetrical wall surface. The extension trajectory of through slots 23 and 24 is the same as the extension trajectory of the active channel 15. That is, the shapes of through slots 23 and 24 are both composed of a 90° arc and a straight line. The connecting piece 25 is slidably connected to through slot 23, and the connecting rod assembly is slidably connected to through slot 24. The cooperation between the connecting piece 25 and through slot 23, the slider and the active channel 15, and the connecting rod assembly and through slot 24 ensure the correctness and stability of the movement direction of the door body 11.

[0048] like Figure 1 and Figure 6As shown, it also includes at least two driven channels 26 with the same shape as the straight channel 22 and at least two driven sliders 27. At least one driven slider 27 is fixedly connected to the top surface and side surface of the door body 11, respectively. The driven sliders 27 are slidably connected within the driven track. The driven channels 26 are parallel to the active channel 15, and at least one driven channel 26 parallel to each active channel 15 is provided. In this embodiment, the number of driven channels 26 and driven sliders 27 are both two. One driven slider 27 is located at a corner of the top surface of the door body 11 away from the metal active slider 16, and the other... The driven slider 27 is positioned on the bottom side of the metal active slider 16 and maintains a distance of three flaps 14 from the metal active slider 16. The driven channel 26 is fixedly connected to the wall and is adapted to the position of the driven slider 27 to ensure that the movement trajectory of the driven slider 27 is smooth. A second connector 42 is provided between the driven slider 27 and the closest flap 14. The shape of the second connector 42 is the same as that of the first connector 25. The two circular surfaces of the second connector 42 are fixedly connected to the door body 11 and the driven slider 27, respectively. The second connector 42 is used to fix the driven slider 27 and the flap 14.

[0049] like Figure 4 , Figure 5 and Figure 6As shown, an installation plate 28 is fixedly connected between the outer walls of the two active channels 15. The width and thickness of the installation plate 28 form an L-shaped cross section and connect the outer walls of the two active channels 15. The power source, namely the geared motor 12, is fixedly connected to the end of the slide plate away from the door body 11. The geared motor 12 is driven by a pulley 37. A pulley 38 is provided at the end of the installation plate 28 away from the first rotating shaft. The pulley 37 and the pulley 38 are connected by a belt 39. Two limiting grooves 29 are provided on the installation plate 28. The length extension direction of the limiting grooves 29 is parallel to the rotation direction of the straight section of the belt 39. The two limiting grooves 29 are respectively opened on two mutually perpendicular surfaces of the installation plate 28, and the angle formed by these two surfaces in the L-shaped cross section is 270°. The length of the limiting groove 29 is equal to the movement distance of the door body 11 driven by the geared motor 12. The linkage assembly is slidably connected to the limiting groove 29. The linkage assembly includes a sliding member 31 slidably connected to the limiting groove 29. 31 is fixedly connected to belt 39, thereby driving the linkage assembly by geared motor 12. The two linkage assemblies are fixedly connected to each other through sliding member 31, that is, the two sliding members 31 are fixedly connected to each other. The surface of sliding member 31 away from the limiting groove 29 is fixedly connected to connecting shaft 1 32. Connecting rod 1 33 is rotatably connected to connecting shaft 1 32. Connecting shaft 2 34 is fixedly connected to the end of connecting rod 1 33 away from connecting shaft 1 32. Connecting rod 2 35 is rotatably connected to the end of connecting shaft 2 34 away from connecting rod 1 33. 5. A connecting rod block 36 is fixedly connected to the end away from the second connecting shaft 34. The connecting rod block 36 is slidably connected to the second through groove 24, and one end of the connecting rod block 36 is supported by the second sliding groove and the mounting plate 28. The other end of the connecting rod block 36 enters the active channel 15 and is connected to the metal active slider 16. The part of the connecting rod block 36 entering the active channel 15 is L-shaped, so as to achieve the effect that the connecting rod blocks 36 belonging to the two linkage mechanisms will not collide and rub against each other, thus affecting the normal operation of this embodiment.

[0050] like Figure 8 As shown, the metal active slider 16 is cylindrical, and the contact point between the electromagnet 17 and the metal active slider 16 is claw-shaped and conforms to the curved surface of the metal active slider 16. It also includes a magnet block 30, which is set on the wall away from the active channel 15. The magnet block 30 and the flap 14 are on the same plane perpendicular to the ground. The flap 14 is made of metal. The magnetic force of the magnet block 30 on the door 11 is less than the magnetic force of the electromagnet 17 on the door 11. The magnet block 30 serves to fix the door 11 when it is in the closed state.

[0051] The usage method of this embodiment is as follows:

[0052] Step 1: The operator judges the size and shape of the object that will pass through the area of ​​the door 11. In this step, the operator has completed the first rough screening of the object. Only objects that the operator has the experience of having the possibility of passing through the area of ​​the door 11 will be allowed to be sent to the door. The operator uses a conventional signal transmitting device to send the corresponding upward or side opening signal to the signal component 13.

[0053] Step 2: When the signal component 13 receives the door opening signal, it selects the corresponding electromagnet 17 to be energized according to the door opening signal, and at the same time starts the power source, i.e., the geared motor 12. This step is a manifestation of conventional technical means in this field and will not be described in detail.

[0054] Step 3: Electromagnet 17 attracts metal active slider 16. The magnetic force of electromagnet 17 on door body 11 exceeds the magnetic force of magnet block 30 on door body 11. Gear motor 12 drives linkage assembly to slide. Flip plate 14 slides in the direction of movement of working electromagnet 17 as the power source rotates. At the same time, adjacent flip plates 14 rotate to adapt to the movement trajectory. The angle between adjacent flip plates 14 rotates from 180° to 135° and then rotates again from 135° to 180° along minor arc channel 21 to complete the door opening.

[0055] Step 4: When an object passes through the area where the door 11 is located, the operator sends a closing signal to this embodiment. When the signal component 13 receives the closing signal, the power source reverses its rotation to drive the flap 14 to slide and rotate, so that the door 11 is reset. Finally, the power supply to the electromagnet 17 is disconnected, completing one door opening and closing cycle. If the object cannot pass through the area where the door 11 is located, proceed to step 5.

[0056] Step 5: Repeat steps 1 to 4. In this step, the opening direction of door 11 will be changed. In this step, the shape of the area that door 11 allows to pass through will be changed by adjusting the opening direction of door 11, in order to try to allow the object to pass through. Since the object has already been preliminarily screened in step 1, the probability of the object passing through after changing the shape of the area that door 11 allows to pass through is high, and the probability of needing to reorganize the object by using other methods that consume manpower and resources is low. Therefore, step 5 increases the allowable range of door 11, improves the efficiency of the object passing through, and reduces additional expenses and consumption.

[0057] This embodiment can be divided into two working states: closed and open. The open state is further divided into top-open and side-open states. In the closed state, the magnet 30 fixes the door 11, and the metal active slider 16 is in its initial position. When the operator sends a signal to open the top surface, this embodiment enters the top-open state. Simultaneously, the reduction motor 12 rotates, driving the linkage assembly via the belt 39. At the same time, the electromagnet 17 in the active channel 15 near the top surface of the door 11 attracts the metal active slider 16. The adjacent flap 14 rotates its axis parallel to the ground and moves towards the active channel 15 near the top, opening the door 11. When a signal is sent to open the side, the reduction motor 12 moves in the same open state as the top surface. The electromagnet 17 in the active channel 15 near the side of the door 11 attracts the metal active slider 16. After the adjacent flap 14 rotates its axis perpendicular to the ground, it moves towards the active channel 15 near the top to open the door 11. Therefore, this embodiment can change the shape of the allowable passage area of ​​the door 11 by changing the opening direction, thereby meeting the needs of different objects to pass through. With the help of the operator to screen the objects, the transportation efficiency is increased and the personnel, money and time costs of replanning and moving the arrangement of objects are reduced.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.

A method of using a two-way flip-type door opener, characterized in that: According to any one of claims 1-6, the method of using a two-way flip-type door opener includes the following steps: Step 1: The operator judges the size and shape of the object that will pass through the area of ​​the door (11) and sends the corresponding door opening signal to the signal component (13) through a conventional signal sending device; Step 2: When the signal component (13) receives the door opening signal, it selects the corresponding electromagnet (17) to be energized according to the door opening signal and starts the power source at the same time; Step 3: The electromagnet (17) attracts the metal active slider (16), the power source drives the linkage assembly to slide, and the flap (14) slides in the direction of the working electromagnet (17) as the power source rotates. At the same time, the adjacent flaps (14) rotate to adapt to the motion trajectory. Step 4: When an object passes through the area where the door (11) is located, the operator sends a closing signal. The signal component (13) receives the closing signal and the power source reverses to drive the flap (14) to slide and rotate, so that the door (11) is reset. Finally, the electromagnet (17) is de-energized to complete one door opening and closing. If the object cannot pass through the area where the door (11) is located, proceed to step 5. Step 5: Repeat steps 1 to 4. In this step 1, the opening direction of the door (11) will be changed.
