Description

Technical Field

[0001] The utility model relates to the technical field of hanging conveying systems, in particular to a full inspection device. Background Art

[0002] In the intelligent hanging conveying system, it is necessary to determine whether the vehicles on the main rail, branch rail or track are full. When the vehicles are full, new vehicles are not allowed to enter to avoid problems such as vehicles falling and causing equipment damage.

[0003] A common solution to the full station problem is to install an infrared or metal proximity switch sensor at the front end of the track entrance, which can detect whether the vehicles have accumulated to the entrance position. If the sensor detects the vehicle, it means that the station is full. If no vehicle is detected, it is considered not full and vehicles can continue to enter. However, the sensor has shortcomings such as short reading range and lack of sensing, which leads to many malfunctions.

[0004] Therefore, how to provide a full inspection device that can effectively determine whether the station is full to prevent carrier backlog and improve production efficiency is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0007] The base is provided with a receiving groove, a photoelectric sensor is installed in the receiving groove, and the photoelectric sensor is provided with a groove;

[0008] The trigger member is located above the accommodating groove. The trigger member is movably connected to the base through a connecting rod assembly. A trigger rod corresponding to the groove is provided at the bottom of the trigger member, so that the trigger member pressed down by the carrier drives the trigger rod to move into the groove to trigger the full detection signal. The connecting rod assembly is provided with an elastic member abutting against the base, so that the trigger member moves out of the groove when the carrier is lifted.

[0009] Preferably, the connecting rod assembly includes at least one first connecting rod and at least one second connecting rod arranged at an interval from each other, one end of the first connecting rod and the second connecting rod are hinged to the trigger member, and the other ends of the first connecting rod and the second connecting rod are hinged to the base, so that the rotating first connecting rod and the second connecting rod drive the trigger member to move downward and upward, and there is at least one elastic member, and the other end of the elastic member abutting against the base abuts against one of the first connecting rod and the second connecting rod.

[0010] Preferably, there are at least two full inspection components, and the full inspection device further comprises at least one connecting piece, and two adjacent full inspection components are fixedly connected via one connecting piece.

[0011] Preferably, each trigger member includes two connecting parts, and the two connecting parts are respectively located at the two ends of the trigger member in the first direction. Both ends of the connecting member in the first direction are provided with connecting heads that cooperate with the connecting parts to enable the same connecting member to be connected to adjacent trigger members.

[0012] Preferably, the connecting portion is provided with a through hole extending along the second direction, and the connecting head is provided with columnar protrusions on both sides in the second direction that can be snap-fitted with the through hole;

[0013] The connecting part also includes two vertical plates and a cover plate located between the two vertical plates. The cover plate is detachable relative to the vertical plates so that the connecting head can be inserted into the connecting part for snap-fitting between the through hole and the columnar protrusion.

[0014] Preferably, the connecting member is further provided with a top plate capable of contacting the vertical plate, and the top plane of the top plate and the top plane of the trigger member are arranged coplanarly.

[0015] Preferably, at least one of the first connecting rod and the second connecting rod is provided with a limiting protrusion, and a limiting piece is correspondingly provided on the base, and the limiting protrusion can abut against the limiting piece to limit excessive rotation of the first connecting rod and the second connecting rod reset by the elastic piece.

[0016] Preferably, a distance between two sides of the groove in the first direction is greater than a length of the trigger rod in the first direction.

[0017] Preferably, the bottom of the trigger rod is a tapered structure, and the tapered structure includes a smaller first end and a larger second end, and the distance between the first end and the groove is smaller than the distance between the second end and the groove.

[0018] Preferably, the base is also provided with a card joint detachably connected to the slide rail.

[0019] Compared with the above-mentioned background technology, the full inspection device provided by the utility model includes at least one full inspection component, which includes a base and a trigger member.

An elastic member abutting against the base is provided on the connecting rod assembly, so that the trigger member moves out of the groove when the carrier is lifted.

[0020] Specifically, when the carrier moves onto the trigger member, the gravity of the carrier drives the connecting rod assembly to rotate relative to the base, and the trigger member moves downward, causing the trigger rod at the bottom of the trigger member to move into the groove, triggering a full detection signal. When the full detection signal continues for a certain period of time, the full detection state is triggered, thereby preventing subsequent carriers from entering. When the carrier moves away, the connecting rod assembly returns to its initial position under the action of the elastic member that has been elastically deformed, and the trigger rod at the bottom of the trigger member moves out of the groove when the carrier is lifted away, releasing the full detection signal. By changing the elastic force of the elastic member, the stroke of the trigger rod in the photoelectric sensor can be changed, avoiding shortcomings such as short reading range and lack of sensing, and can effectively determine whether it is full to prevent carrier backlogs and improve production efficiency.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] In the description of the present invention, it should be understood that the terms "top" and "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0039] The utility model aims to provide a full inspection device, which can effectively judge whether the station is full to prevent the backlog of carriers and improve production efficiency.

[0040] It should be noted that, in this embodiment, the X direction in the drawings is defined as the first direction, and the Y direction is defined as the second direction, and the first direction and the second direction are perpendicular to each other.

[0041] See also Figures 1 to 4 To achieve the above-mentioned purpose, the utility model provides a full inspection device, including at least one full inspection component, and the full inspection component includes a base 1 and a trigger member 2.

[0042] The base 1 is provided with a receiving groove with a receiving space, and a photoelectric sensor 11 is installed in the receiving groove. The photoelectric sensor 11 is provided with a groove 12. The groove 12 is formed by connecting two first vertical plates spaced apart in a first direction and a second vertical plate connecting the two first vertical plates. The two first vertical plates are respectively used to install a light transmitter and a receiver. The light transmitter is used to emit infrared light or visible light. The light receiver can receive the light without obstruction. However, when the object to be detected passes through the groove, the light is blocked, and the photoelectric switch is activated to output a signal.

[0043] The trigger member 2 is located above the accommodating groove, and the trigger member 2 is movably connected to the base 1 through a connecting rod assembly. A trigger rod 21 corresponding to the groove 12 is provided at the bottom of the trigger member 2, so that the trigger member 2 pressed down by the carrier drives the trigger rod 21 to move into the groove 12 to trigger a full detection signal. An elastic member 31 abutting against the base 1 is provided on the connecting rod assembly, so that the trigger member 2 moves out of the groove 12 when the carrier is lifted.

[0044] In this embodiment, the distance between the two sides of the groove 12 in the first direction (the two first vertical plates) is greater than the length of the trigger rod 21 in the first direction, so as to provide the required moving space for the trigger rod 21 when the trigger member 2 moves downward. Preferably, the distance between the two sides of the groove 12 in the first direction is three times the length of the trigger rod 21 in the first direction. The length relationship can also be determined according to the displacement of the trigger rod 21 in the first direction in actual conditions. For example, in the initial state, the trigger rod 21 is located above one side of the groove 12 in the first direction. In the fully loaded state, the trigger rod 21 is spaced smaller than the other side of the groove 12 in the first direction.

[0045] See also Figures 5 to 8 The bottom of the trigger rod 21 adopts a tapered structure 211, and the tapered structure 211 includes a smaller first end and a larger second end. In the initial state, the distance between the first end and the groove 12 is smaller than the distance between the second end and the groove 12. The bottom of the trigger rod 21 with the tapered structure 211 can reduce the size of the trigger rod 21 to avoid collision with other components during the movement of the trigger rod 21. At the same time, reducing the size of the trigger rod 21 can cooperate with a narrower photoelectric sensor 11 to release the accommodation space in the base 1.

[0046] When the carrier moves onto the trigger member 2, the gravity of the carrier drives the connecting rod assembly to rotate relative to the base 1, and the trigger member 2 moves downward, causing the trigger rod 21 provided at the bottom of the trigger member 2 to move into the groove 12, triggering a full detection signal. When the full detection signal continues for a certain period of time, the full detection state is triggered, thereby preventing subsequent carriers from entering. When the carrier moves away, the connecting rod assembly returns to its initial position under the action of the elastic member 31 that has been elastically deformed. The trigger rod 21 provided at the bottom of the trigger member 2 moves out of the groove 12 when it is not pressed down by the carrier, and the full detection signal is released. By changing the elastic force of the elastic member 31, the stroke of the trigger rod 21 in the photoelectric sensor 11 can be changed, avoiding the shortcomings of short reading range and lack of sensing, and can effectively judge whether it is full to prevent carrier backlog and improve production efficiency.

[0047] The connecting rod assembly includes at least one first connecting rod 3 and at least one second connecting rod 4 which are spaced apart from each other, one end of the first connecting rod 3 and the second connecting rod 4 are both hinged to the trigger member 2, and the other ends of the first connecting rod 3 and the second connecting rod 4 are hinged to the base 1, so that the rotating first connecting rod 3 and the second connecting rod 4 drive the trigger member 2 to move downward and upward, at least one elastic member 31 is provided, and the other end of the elastic member 31 abutting against the base 1 abuts against one of the first connecting rod 3 and the second connecting rod 4, the elastic member 31 can be a spring, etc., the first connecting rod 3 and / or the second connecting rod 4 are both provided with a first boss on one side abutting against the elastic member 31, and a second boss is provided on the base 1 on one side abutting against the elastic member 31, and the first boss and the second boss extend into the axial ends of the elastic member 31 to radially limit the elastic member 31, avoid radial movement of the elastic member 31 during the force deformation process, and ensure that the elastic member 31 is only elongated or shortened along the axial direction.

[0048] In some embodiments, at least one of the first link 3 and the second link 4 is provided with a limiting protrusion 32, and a limiting member 13 is correspondingly provided on the base 1. The limiting protrusion 32 can abut against the limiting member 13 to limit the movement of the first link 3 and / or the second link 4 with the limiting protrusion 32, thereby preventing the first link 3 and the second link 4 reset by the elastic member 31 from excessive rotation, thereby ensuring the initial position of the trigger member 2 when no vehicle enters.

[0049] Taking into account the convenience of production and installation, the first link 3 and the second link 4 can adopt the same structure, that is, the first link 3 and the second link 4 only differ in the installation position. The first link 3, the second link 4, the base 1 and the trigger member 2 constitute a parallelogram structure, and the four sides of the parallelogram are hinged. When the vehicle enters the trigger member 2, the parallelogram is pressed and tilted to one side, causing the trigger rod 21 to move into the groove 12 of the photoelectric sensor 11. When the vehicle moves out of the trigger member 2, the two side sides of the parallelogram return to the initial position under the elastic force of the elastic member 31, and the trigger rod 21 moves out of the groove 12 of the photoelectric sensor 11.

[0050] In addition, in order to avoid excessive downward movement of the trigger member 2 due to its gravity when there are too many vehicles, it is possible to consider adding a limiting top block to the base 1, and at least one of the first connecting rod 3, the second connecting rod 4 and the trigger member 2 is provided with an abutment. When the first connecting rod 3 and / or the second connecting rod 4 are provided with an abutment, after the trigger member 2 moves down to a certain position, the first connecting rod 3 and the second connecting rod 4 rotate until the abutment abuts the limiting top block. At this time, the trigger member 2 cannot move further downward, and the limiting top block can support the abutment. At the same time, it is possible to consider appropriately increasing the structural strength of the first connecting rod 3 and the second connecting rod 4 to avoid deformation or breakage in this process; when the trigger member 2 is provided with an abutment, after the trigger member 2 moves down to a certain position, the abutment abuts the limiting top block. At this time, the trigger member 2 cannot move further downward, and the base 1 supports the abutment through the limiting top block to avoid excessive force on the abutment and / or the connecting rod assembly.

[0051] In another embodiment, there are at least two full inspection components, and the full inspection device also includes at least one connecting member 5. Two adjacent full inspection components are fixedly connected by a connecting member 5. The trigger member 2 includes two connecting parts 22, and the two connecting parts 22 are respectively located at the two ends of the trigger member 2 in the first direction. Both ends of the connecting member 5 in the first direction are provided with connecting heads that cooperate with the connecting parts 22, so that the same connecting member 5 is connected to adjacent trigger members 2.

[0052] Taking two full-inspection components as an example, the bases 1 of the two full-inspection components are arranged adjacent to each other in the first direction, and a connecting part 22 is provided at one end close to the trigger components 2 of the two full-inspection components. The connecting heads provided at both ends of the connecting member 5 are snap-fitted with the corresponding connecting part 22, so that the two full-inspection components are fixedly connected. The length of the connecting member 5 in the first direction can be adjusted according to the gap requirements between the two adjacent full-inspection components.

[0053] Among them, the connecting part 22 is provided with a through hole 221 extending along the second direction, and the connecting head is provided with columnar protrusions 51 on both sides in the second direction that can be snap-fitted with the through hole 221; the connecting part 22 also includes two vertical plates 222 and a cover plate 223 located between the two vertical plates 222, and the cover plate 223 is detachable relative to the vertical plate 222. When the connecting member 5 is required to connect adjacent full-inspection components, the corresponding cover plate 223 is removed to allow the connecting head to be inserted into the corresponding connecting part 22 for snap-fitting between the through hole 221 and the columnar protrusion 51.

[0054] In this embodiment, the connecting member 5 is also provided with a top plate 52 capable of contacting the vertical plate 222, and the vertical plate 222 supports the top plate 52, thereby supporting the carrier located above the top plate 52. The top plane of the top plate 52 and the top plane of the trigger member 2 are arranged coplanarly to facilitate the movement of the carrier on adjacent full-inspection components. The trigger members 2 of each full-inspection component are interconnected as a whole through the connecting member 5, and can move down and up at the same time to increase the length of the full-inspection component in the first direction, so as to expand the number of carriers accommodated on the full-inspection device. The base 1 is also provided with a card joint 14 detachably connected to the slide rail to facilitate the installation and disassembly of the full-inspection device.

[0055] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0056] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0057] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
