[0024] Figure 1 The structure diagram of an automatic parking device for an easily twisted moving device provided in an embodiment of the present application is as follows: Figure 1 As shown, the automatic parking device includes: an operating platform 1, an elastic element 2, a limit switch 3 and a control circuit 4; the operating platform 1 includes a base 101, a connecting portion 102 and a platform 103, one side of the connecting portion 102 is connected to the base 101, and the other side of the connecting portion 102 is hinged to the edge of the platform 103, and the platform 103 is located above the base 101, and an elastic element 2 and a limit switch 3 are provided between the platform 103 and the base 101. When the elastic element 2 is in an unstressed state, the platform 103 does not trigger the limit switch 3, and the control circuit 4 is respectively connected to the limit switch 3 and the easy-to-entangle motion device.

[0025] Easy-to-entangle moving equipment refers to those mechanical equipment that have the risk of clothing, hair, fingers or other objects being caught in rotating parts during operation, such as the eight-mouth packaging machine mentioned above. The embodiment of this application does not limit the shape and size of the operating platform 1. Figure 1 As shown, the base 101 and platform 103 are both rectangular parallelepiped-shaped, and the connecting portion 102 may be a connecting rod or connecting plate, etc. The articulation may be achieved via a rotating shaft or hinge, etc. The embodiment of the present application does not specifically limit the elastic element 2; a spring is typically employed. The elastic element 2 and the travel switch 3 may be disposed on the bottom surface of the platform 103 or on the top surface of the base 101.

[0026] When the operator enters the platform 103, the elastic element 2 is compressed downward by the downward gravity of the operator, and the platform 103 produces a downward displacement, thereby triggering the action of the limit switch 3, the normally open contact is closed, the control circuit 4 obtains the signal, the easily entangled moving equipment can be started normally, and the operator is normally bagged; when the operator leaves the operating platform 1 or is accidentally entangled by the equipment, the downward gravity of the operator disappears on the elastic element 2, the elastic element 2 rebounds, the platform 103 is displaced upward and reset, the limit switch 3 is reset, the closed normally open contact is reset and disconnected, the control circuit 4 obtains the signal, and the easily entangled moving equipment stops.

[0027] An embodiment of the present application provides an automatic parking device for easily entangled moving equipment, comprising: an operating platform, an elastic element, a travel switch and a control circuit; the operating platform comprises a base, a connecting portion and a platform, one side of the connecting portion is connected to the base, and the other side of the connecting portion is hinged to the edge of the platform, and the platform is located above the base, an elastic element and a travel switch are provided between the platform and the base, and when the elastic element is in an unstressed state, the platform does not trigger the travel switch, and the control circuit connects the travel switch and the easily entangled moving equipment respectively. The travel switch and the elastic element cooperate to detect whether there is an operator on the platform. When the operator leaves the operating platform or is accidentally entangled by the equipment, the control circuit controls the easily entangled moving equipment to stop working according to the disconnect signal of the travel switch, thereby effectively preventing the operator from being accidentally entangled in the moving equipment. In addition, the automatic parking device is stable and reliable, has low manufacturing and maintenance costs, a simple structure, is easy to install, and has a wide range of applications.

[0028] Based on the above embodiments, the embodiments of the present application also include a limit tripod 5, which is arranged on the bottom surface of the platform 103 and / or the top surface of the base 101. The limit tripod 5 is located between the base 101 and the platform 103, and the length of the limit tripod 5 is the distance between the platform 103 and the base 101 when the platform 103 triggers the limit switch 3.

[0029] The embodiment of the present application does not specifically limit the number of position limiting legs 5, and multiple positions may be provided. By providing the position limiting legs 5, when the platform 103 triggers the limit switch 3, in addition to the elastic element 2 providing support, the position limiting legs 5 can also provide support, thereby reducing the force exerted by the platform 103 on the limit switch 3, preventing damage to the limit switch 3, and increasing the service life of the limit switch 3. The position limiting legs 5 are fixedly connected to the bottom surface of the platform 103 and / or the position limiting legs 5 are fixedly connected to the top surface of the base 101.

[0030] Based on the above embodiment, the connecting portion 102 of the embodiment of the present application is a connecting plate, one side of the connecting plate is fixedly connected to the edge of the base 101, and the other side of the connecting plate is hinged to the edge of the platform 103 through a hinge.

[0031] like Figure 1As shown, the base 101 and platform 103 are rectangular steel plates of equal size. The lengths of the two sides of the connecting plate are adapted to the edges of the base 101 and the platform 103, respectively. One side of the connecting plate is fixedly connected to the edge of the base 101, and the other side of the connecting plate is hinged to the edge of the platform 103. This design is simple and relatively strong.

[0032] Based on this, and considering the cost, there are two limit legs 5 , and the two limit legs 5 , the limit switch 3 and the elastic element 2 are all located on opposite sides of the connecting plate, and the limit switch 3 and the elastic element 2 are located between the two limit legs 5 .

[0033] like Figure 1 As shown, the two limit legs 5 are respectively located at the two ends of the edge of one side of the platform 103, and the two limit legs 5 are fixedly connected to the bottom surface of the platform 103. The limit switch 3 and the elastic element 2 are arranged between the two limit legs 5, and the limit switch 3 and the elastic element 2 are arranged on the top surface of the base 101. The limit legs 5 located on both sides of the limit switch 3 can well balance the force exerted on the platform 103 by the operator.

[0034] Based on the above embodiment, a pressure sensor is provided at the bottom of the limiting footrest 5 in the embodiment of the present application, and the pressure sensor is connected to the control circuit 4. By providing the pressure sensor to detect the pressure and feeding the pressure back to the control circuit 4, the contact between the operator and the platform 103 can be detected more accurately, thereby preventing other objects from coming into contact with the platform 103.

[0035] Based on the above embodiment, the edge of platform 103 in this embodiment of the present application is detachably connected to a guardrail, and the top surface of platform 103 is provided with an anti-slip layer. Specifically, mounting holes can be provided around the edge of platform 103, and the guardrail can be plugged into the mounting holes. The provision of the guardrail can provide a certain degree of protection. The embodiment of the present application does not specifically limit the anti-slip layer; it can be a rubber layer attached to the surface of platform 103. The provision of the rubber layer can provide sufficient friction to prevent slipping, while also avoiding foot discomfort caused by a hard surface.

[0036] Based on the above embodiment, the embodiment of the present application further includes a lifting platform for carrying the operating platform 1, which is provided at the bottom of the base 101 and is used to adjust the height of the operating platform 1. By providing the lifting platform, the operator can conveniently adjust the height of the operating platform 1 according to his or her own height.

[0037] Based on the above embodiment, the embodiment of the present application also includes an operation box 6, which is provided with a manual switch 7, a start switch 8, a stop switch 9 and an emergency stop switch 10 connected to the control loop 4. The manual switch 7 is used to respond to the user's instruction to temporarily leave.

[0038] Specifically, the normally open contact of the travel switch 3 is connected in parallel with the normally open contact of the manual switch 7, and then connected in series with the start, stop, and emergency stop (normally closed) contacts of the control circuit 4.

[0039] When the operator enters the operating platform 1 (the manual switch 7 is in the automatic position), the elastic element 2 is compressed downward by the downward gravity of the operator, the operating platform 1 is displaced downward, the trigger-type travel switch 3 is actuated, the normally open contact is closed, the easily entangled moving equipment can be started normally, and the operator is normally bagged; when the operator leaves the operating platform 1 or is accidentally entangled by the equipment, the downward gravity of the operator disappears on the elastic element 2, the elastic element 2 rebounds, the operating platform 1 is displaced upward and reset, the travel switch 3 is reset, the closed normally open contact is reset and disconnected, and the easily entangled moving equipment stops; if the operator needs to temporarily leave the operating platform 1 and the equipment needs to continue running, the manual switch 7 can be switched to the manual position, and after returning to the operating platform 1, the manual switch 7 can be switched to the automatic position, and the control circuit 4 can continue to control the start or stop of the easily entangled moving equipment according to the signal of the travel switch 3.

[0040] Based on the above embodiment, the present embodiment further includes a camera and an alarm device connected to the control circuit 4. The camera can be placed next to the operating platform 1 to monitor the operating platform 1 area in real time. Once abnormal behavior or signs of an operator being entangled are detected, the control circuit 4 controls the entanglement-prone moving equipment to pause and simultaneously controls the alarm device to sound an alarm to alert surrounding personnel. In other words, the control circuit 4 can control the start and stop of the entanglement-prone moving equipment based on signals fed back from the limit switch 3 or based on operator behavior detected by the camera, making it safer and more reliable.

[0041] Finally, the present application also provides an anti-entanglement system, comprising an easy-entanglement device and the above-mentioned automatic parking device. Since the automatic parking device has been introduced in detail above, it will not be repeated here.

The automatic parking device includes: an operating platform, an elastic element, a travel switch and a control circuit; the operating platform includes a base, a connecting part and a platform, one side of the connecting part is connected to the base, and the other side of the connecting part is hinged to the edge of the platform, and the platform is located above the base, and an elastic element and a travel switch are provided between the platform and the base. When the elastic element is in an unstressed state, the platform does not trigger the travel switch, and the control circuit connects the travel switch and the moving device that is prone to entanglement respectively. The travel switch and the elastic element cooperate to detect whether there is an operator on the platform. When the operator leaves the operating platform or is accidentally entangled by the equipment, the control circuit controls the moving device that is prone to entanglement to stop working according to the disconnection signal of the travel switch, thereby effectively preventing the operator from being accidentally entangled in the moving device.
