Description

Technical Field

[0001] The utility model relates to the technical field of ready-to-wear system equipment, and particularly relates to a Hall recognition hanger induction device. Background Art

[0002] The ready-to-wear system is applied in garment manufacturing enterprises and is used to run hangers holding fabrics. The structure of the ready-to-wear system includes a main track. Along the direction of the main track, several workstations are provided. The hanger holding the fabric enters the target workstation from the main track. After the corresponding process is completed on the fabric, the hanger still needs to enter the main track so as to enter the next target workstation. In actual operation, to ensure the working efficiency of the ready-to-wear system, there are many hangers running on the ready-to-wear system. And due to the high requirement for the sequence during the operation of the ready-to-wear system, it will inevitably lead to the backlog of hangers in front of some bottleneck processes. If too many hangers are backlogged and more hangers continue to enter, the hangers will fall off, thus bringing trouble to the work.

[0003] For example, in the patent - ready-to-wear system hanger induction device with the publication number CN104055260A, it includes a micro switch and a trigger mechanism. The trigger mechanism is used to contact the hanger. The position change generated after the trigger mechanism contacts the hanger acts on the contact point on the micro switch. Its characteristics are that the trigger mechanism includes a sheet-shaped trigger plate. One end side of the trigger plate has a pivot point, the other end of the trigger plate is a free end. A limiting structure for limiting the position of the trigger plate is provided on the inner side in the width direction of the trigger plate. Under the action of gravity, the position of the free end of the trigger plate is lower than the position of the hinged end. An inclined opening is formed at the lower corner of the free end of the trigger plate. The micro switch is essentially a mechanical trigger. The contact point on the micro switch is triggered by the trigger mechanism. However, occasionally when the hanger passes through the induction device, the trigger mechanism is prone to not trigger the contact point and the hanger just passes by, resulting in non-triggering.

[0004] For example, in the patent - a hanger induction device with the publication number CN220578215U, it includes a front cover and a rear cover. The rear cover is detachably arranged on the front cover. Avoidance grooves corresponding to each other are formed on both the front cover and the rear cover. An induction sheet is rotatably arranged in the front cover and the induction sheet can rotatably pass through the two avoidance grooves. A groove-shaped photoelectric switch is arranged in the front cover and the notch of the groove-shaped photoelectric switch faces the rear cover. The groove-shaped photoelectric switch includes induction points arranged on two opposite side walls. An induction foot is fixedly arranged on the induction sheet and the induction foot is rotatably arranged in the notch of the groove-shaped photoelectric switch. The photoelectric switch is seriously affected by the environment. The light in the workshop easily affects the photoelectric switch, resulting in false triggering or non-triggering. Summary of the Utility Model

[0005] Technical Problems to be Solved by the Utility Model

[0006] In view of the technical problems that existing hanger induction devices are prone to false triggering or non-triggering, the present utility model provides a Hall recognition hanger induction device, which can be triggered within a certain distance range, avoiding the non-triggering situation caused by insufficient triggering distance, and the triggering is not easily affected by the environment, greatly reducing the situation of false triggering.

[0007] Technical solution

[0008] To solve the above problems, the technical solution provided by the present utility model is as follows:

[0009] A Hall recognition hanger induction device includes a U-shaped frame and a guide rail. The guide rail is installed on the U-shaped frame. It also includes a Hall sensor and a trigger plate. An induction magnet is provided on the trigger plate and cooperates with the Hall sensor to trigger. The trigger plate faces the guide rail. The trigger plate is provided with a moving trigger structure for cooperating with the hanger, and the moving trigger structure converts the movement of the hanger into the vertical movement of the trigger plate.

[0010] The U-shaped frame is the basic frame of the whole device, used to support other components. The guide rail is installed on the U-shaped frame and is used to guide the hanger to move along the path of the guide rail. The Hall sensor is a magnetic sensor that can sense the change of the magnetic field and convert it into an electrical signal output. Using the Hall sensor as the trigger mechanism can avoid the disadvantage that the photoelectric switch is easily affected by the photoelectric environment. The Hall sensor is only affected by the electromagnetic environment, and the electromagnetic environment in general workshops is very stable and will not affect the Hall sensor. Therefore, its performance is stable and reliable. The trigger plate is a plate member equipped with an induction magnet. When it moves into the effective induction range of the Hall sensor, it will trigger the Hall sensor. The trigger plate is touched and pushed by the hanger and can move into the effective induction range of the Hall sensor. The vertical movement trigger of the trigger plate can be reset by its own gravity and continue to receive the trigger of the next hanger. The design allows triggering within a certain distance range, which means that even if the hanger is not completely aligned with the sensor, it can still be detected, thus avoiding the undetected problem caused by position deviation.

[0011] Optionally, the moving trigger structure is an inclined surface at the bottom of the trigger plate. One end of the trigger plate is a hinge point, and the other end is a free end. The induction magnet is located at the free end, and one end of the trigger plate is hinged to the induction cover.

[0012] The inclined surface will be contacted and pushed during the movement of the hanger, causing the trigger plate to rotate a certain angle around the hinge point. One end of the trigger plate is a fixed hinge point, which is connected to the induction cover, enabling the trigger plate to rotate around this point. The other end of the trigger plate is a free end, and an induction magnet is installed on it to trigger the Hall sensor.

[0013] Optionally, a limiting hole is provided on the trigger plate, and a limiting pin is provided in cooperation with the limiting hole.

[0014] The limit pin is inserted into the limit hole to limit the movement range of the trigger plate.

[0015] Optionally, a first repulsive magnet is provided on the trigger plate, and a second repulsive magnet is provided at the corresponding position of the induction cover, and the first repulsive magnet and the second repulsive magnet repel each other.

[0016] Reset is carried out by using the gravity of the trigger plate. When the trigger plate is pushed too hard and quickly by the clothes hanger, it may get stuck. At this time, it is impossible to reset by using the gravity of the trigger plate. The first repulsive magnet and the second repulsive magnet can provide repulsive force to help reset, and can accelerate the reset speed to adapt to the rapid movement and rapid triggering of the clothes hanger.

[0017] Optionally, the trigger plate rotates in the induction cover. A strip-shaped groove for accommodating the trigger plate is provided in the induction cover. Limit stop edges are provided on both sides of the trigger plate, and the width of the strip-shaped groove is the same as that of the limit stop edges.

[0018] The strip-shaped groove is used to accommodate the trigger plate. Limit stop edges with the same width as the strip-shaped groove are provided on both sides of the trigger plate, so that the trigger plate can slide smoothly in the strip-shaped groove without shaking left and right.

[0019] Optionally, a clamping edge is provided on the outside of the induction cover, and a clamping groove for cooperating with the clamping edge is provided on the C-shaped frame.

[0020] The clamping edge and the clamping groove are used for clamping connection. Compared with screw connection, quick disassembly and quick assembly can be realized, saving assembly time.

[0021] Optionally, a wear-resistant coating is provided on the inclined surface.

[0022] The wear-resistant coating can significantly reduce the wear of the inclined surface caused by long-term use, thereby prolonging the overall service life of the trigger plate.

[0023] Optionally, the trigger plate is of an integrally formed structure.

[0024] The integrally formed structure has higher strength and rigidity compared with the spliced or welded structure, and can better resist external impacts and stresses.

[0025] Beneficial effects

[0026] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0027] The technical solution provided by the present utility model includes a Hall sensor and a trigger plate. An induction magnet is provided on the trigger plate and cooperates with the Hall sensor to trigger. The trigger plate faces the guide rail. The trigger plate is provided with a moving trigger structure that cooperates with the clothes hanger. The moving trigger structure converts the movement of the clothes hanger into the vertical movement of the trigger plate. By precisely setting the trigger conditions, the probability of false triggering caused by environmental factors (such as the approach of other metal objects) can be effectively reduced. The Hall sensor is sensitive to magnetic fields but is relatively unaffected by non-magnetic substances, so its performance is stable and reliable. The design allows triggering within a certain distance range, which means that even if the clothes hanger is not completely aligned with the sensor, it can still be detected, thus avoiding the problem of undetected due to position deviation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the drawings and embodiments.

[0035] Embodiment

[0036] Combined with the attached Figure 1A Hall recognition hanger sensing device includes a 匚-shaped frame 1, a guide rail 3, and a sensing box 2. The 匚-shaped frame 1 is a frame with a 匚-shaped cross section. The 匚-shaped frame 1 has an upper end side and a lower end side, and the middle is connected by a vertical wall. The sensing box 2 includes a sensing cover 201 and a trigger plate 202. The sensing cover 201 is provided with a clamping edge 2011 on the outside. The 匚-shaped frame 1 is provided with a clamping groove 101 that is engaged with the clamping edge 2011. Figure 3 As shown. The card slot 101 is located at the upper end side, and the induction box 2 is inserted and connected from the axial direction of the shaped frame 1. The guide rail 3 is connected to the lower end side, and the guide rail 3 is arranged in parallel with the trigger plate 202. The trigger plate 202 is opposite to the guide rail 3, and the hanger moves along the guide rail 3, which makes it convenient to push the trigger plate 202.

[0037] Combined with Figure 2 , the trigger plate 202 is provided with limiting ribs 206 on both sides, and the strip groove has the same width as the limiting ribs 206. The trigger plate 202 rotates in the sensing cover 201, and the sensing cover 201 is provided with a strip groove for accommodating the trigger plate 202. The cooperation between the limiting ribs 206 and the strip groove limits the moving track of the trigger plate 202, ensuring that the trigger plate 202 can only rotate in a predetermined direction, such as Figure 3 shown.

[0038] Combined with Figure 4 , the trigger plate 202 is provided with an induction magnet 204 and cooperates with the Hall sensor 203 to trigger. The induction magnet 204 is located at the top of the free end of the limit retaining edge 206, and the Hall sensor 203 is set at this position of the induction cover 201. The Hall sensor 203 is fixed by the sensor cover, and the sensor cover is fixed by screws. If the Hall sensor 203 is damaged, it can be quickly removed and replaced by using the card slot 101 and the card edge 2011 of the 匚-shaped frame 1. The Hall sensor 203 can adjust the sensing distance range to adapt to the actual distance that the hanger pushes the trigger plate 202, avoiding the problem of non-detection due to position deviation. Combined with the attached Figure 3 , 5 The card slot 101 and the card edge 2011 are mutually engaged structures, and the card edge is below the card slot 101. Below the card edge 2011 is the card slot, and one end of the card slot is provided with a contact wall 2014 for limiting, and the other end is an opening, and the induction cover 201 is inserted from the opening end.

[0039] The trigger plate 202 is provided with a repulsive magnet 205, and a corresponding position on the induction cover 201 is provided with a repulsive magnet 2012. The repulsive magnet 205 and the repulsive magnet 2012 repel each other. The mutual repulsion of the two magnets helps the trigger plate 202 to automatically reset in the non-activated state. Once the clothes hanger is removed, the trigger plate 202 automatically returns to its initial position under the action of the repulsive force between the repulsive magnets. Select appropriate magnet types and sizes to ensure that the repulsive force is sufficient to stably trigger the trigger plate 202, while not being too strong to make the trigger plate 202 difficult to be activated. Ensure that the positions of the repulsive magnet 205 and the repulsive magnet 2012 are accurate so that the correct repulsive force can be generated when the trigger plate 202 resets.

[0040] The trigger plate 202 is provided with a moving trigger structure that cooperates with the clothes hanger. The moving trigger structure converts the movement of the clothes hanger into the vertical movement of the trigger plate 202. The moving trigger structure is an inclined surface 2013 at the bottom of the trigger plate 202. One end of the trigger plate 202 is a hinge point, and the other end is a free end. The induction magnet 204 is located at the free end. One end of the trigger plate 202 is hinged to the induction cover 201. When the clothes hanger moves on the guide rail 3 and contacts the inclined surface 2013 at the bottom of the trigger plate 202, the pressure received by the inclined surface 2013 causes the trigger plate 202 to start rotating around the hinge point. The rotation of the trigger plate 202 makes the induction magnet 204 on the free end approach the Hall sensor 203.

[0041] The hinge point is a rotating shaft 2010 and a rotating hole 209. The rotating shaft 2010 is fixedly connected inside the induction cover 201, and the rotating hole 209 is located at the hinge point end of the trigger plate 202. The trigger plate 202 is provided with a limiting hole 207, and a limiting pin 208 is cooperatively arranged in the limiting hole 207. The limiting hole 207 is a vertical waist-shaped hole, and the limiting pin 208 moves up and down in it. Since the length of the limiting hole 207 is small, the rotation amplitude of the trigger plate 202 is also small and can be regarded as a vertical movement. Similarly, the mechanism of the trigger plate 202 can be designed as a true vertical movement structure composed of a vertical guide rail 3. The bottom of the trigger plate 202 is also an inclined surface 2013, which is pushed upward by the movement of the clothes hanger.

[0042] The surface of the inclined surface 2013 is provided with a wear-resistant coating. Commonly used wear-resistant coating materials include but are not limited to polyurethane, polytetrafluoroethylene (PTFE), tungsten carbide, etc. Select appropriate wear-resistant coating materials according to the use environment and expected use frequency. For example, in applications that require high wear resistance, tungsten carbide may be a better choice; while in cases where a lower coefficient of friction is required, PTFE may be a better choice.

[0043] The trigger plate 202 is an integrally formed structure to improve the structural strength.

[0044] The above has schematically described the present utility model and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design without creative efforts a structural mode and an embodiment similar to the technical solution, they shall fall within the protection scope of the present utility model.
