Description

Technical Field

[0001] The present application relates to the technical field of container production, and in particular to a container conveying device with a safety anti-pinch mechanism. Background Art

[0002] A container is a group of tools that can be used to transport packaged or unpackaged goods and is easy to load, unload and transport using mechanical equipment.

[0003] refer to Figure 1 The container conveying device includes two conveyor belts mounted on the ground and an inspection platform 2 located on one side. The bottom of the container 4 has a roller structure that cooperates with the two conveyor belts. The container has a protrusion 41 on the side near the inspection platform 2. When a worker stands on the side of the inspection platform 2 facing the input direction of the container 4, this area is defined as a danger zone 5. The protrusion 41 can easily strike the worker's feet, causing them to trip and become trapped between the container 4 and the inspection platform 2, posing a safety hazard.

[0004] In view of the above-mentioned related technologies, the inventors have devised a container conveying device with a safety anti-pinch mechanism. Utility Model Content

[0005] In order to reduce the probability of operators being pinched by containers and inspection platforms, the present application provides a container conveying device with a safety anti-pinch mechanism.

[0006] The container conveying device provided in this application has a safety anti-pinch mechanism and adopts the following technical solutions:

[0007] A container conveying device with a safety anti-pinch mechanism comprises a conveying mechanism, a detection platform located on one side of the conveying mechanism, and a safety anti-pinch mechanism installed on the detection platform; the detection platform has a first side surface perpendicular to the conveying direction of the conveying mechanism and close to the entrance side of the conveying mechanism; the safety anti-pinch mechanism is arranged on the first side surface; the safety anti-pinch mechanism comprises a safety plate, a touch switch installed on the detection platform and electrically connected to the conveying mechanism, and a control connecting rod connecting the touch switch and the safety plate; the safety plate is rotatably installed on the detection platform and has a first workstation and a second workstation, the second workstation being located on a side of the first workstation close to the detection platform; when the safety plate is in the first workstation, the touch switch is in an on state; when the safety plate is in the second workstation, the touch switch is in a off state.

[0008] By adopting the above technical solution, during the normal transportation and maintenance of the container, the safety piece is in the first position and the touch switch is in the on state, so the conveying mechanism operates normally to transport the container. When an operator is tripped by the protruding locking component of the container, the operator's fall will cause the safety piece in the safety anti-pinch mechanism to tilt toward the direction close to the detection platform, so that the safety piece is in the second position, thereby closing the touch switch and stopping the conveying mechanism, reducing the probability of the operator being pinched by the container and the detection platform, and helping to improve the safety of the operator's operation during the transportation and maintenance of the container.

[0009] Optionally, the control link has a first mounting post and a second mounting post at both ends, the safety plate has a mounting slot for arranging the first mounting post, and the touch rod of the touch switch has a strip hole for slidably arranging the second mounting post.

[0010] By adopting this technical solution, the first and second mounting posts at each end of the control link respectively mate with the mounting slots of the safety plate and the strip-shaped holes of the touch switch, ensuring that the safety plate accurately triggers the state changes of the touch switch at different working positions, improving the response speed and reliability of the safety anti-pinch mechanism. This structural design also makes installation and maintenance more convenient and reduces the failure rate.

[0011] Optionally, the control link is provided with rubber sleeves at the first mounting post and the second mounting post.

[0012] By adopting the above technical solution, the rubber sleeve can effectively reduce the probability of the control link loosening or falling off during operation, thereby ensuring a stable connection between the control link, the safety plate and the touch switch, and improving the reliability and safety of the system.

[0013] Optionally, the safety piece includes a first straight piece extending in a direction away from the detection platform and a second straight piece connected to the first straight piece and bent toward the detection platform.

[0014] By adopting the above technical solution, the second straight piece is bent toward the detection platform, so that when an operator encounters a safety accident, the touch switch can be triggered more sensitively, ensuring that the conveying mechanism is stopped in time and reducing the probability of pinching accidents.

[0015] Optionally, the second straight piece sleeve is provided with a protective sleeve.

[0016] By adopting the above technical solution, the provision of the protective cover helps to reduce the probability of the second straight piece causing harm to the operator when the safety anti-pinch mechanism is triggered.

[0017] Optionally, a mounting seat for mounting the safety sheet is provided on the first side surface of the detection platform, and a rotating torsion spring is provided in the mounting seat for driving the safety sheet to always have a tendency to be in the first working position.

[0018] By adopting this technical solution, the mounting base allows the safety plate to be stably mounted on the first side of the detection platform, ensuring that the safety plate can be smoothly switched between the first and second positions. The rotating torsion spring provides a continuous force to keep the safety plate in the first position when no external force is applied, thereby ensuring that the touch switch remains in the open state and improving the reliability and safety of the system.

[0019] Optionally, the detection platform has a second side surface arranged opposite to the first side surface, and the second side surface is provided with a safety anti-pinch mechanism.

[0020] By adopting the above technical solution, a safety anti-pinch mechanism is also set on the second side of the detection platform, which further improves the safety performance of the entire device, reduces the probability of pinching accidents when the container enters or leaves the conveying mechanism, and ensures the personal safety of the operator.

[0021] Optionally, the detection platform has a mounting plate for arranging the touch switch, the mounting plate is provided with a guide rail, and the touch switch has a guide slider for cooperating with the guide rail.

[0022] By adopting the above technical solution, the detachable connection between the touch switch and the mounting plate is achieved through the cooperation between the guide rail and the guide slider, which is helpful for repairing and replacing the touch switch.

[0023] Optionally, the guide rail is provided with a positioning groove, the guide slider is provided with a plunger hole and a ball spring plunger is provided in the plunger hole. When the touch switch is installed on the mounting plate, the plunger ball head of the ball spring plunger is clamped in the positioning groove.

[0024] By adopting the above technical solution, the plunger ball head of the ball head spring plunger is clamped in the positioning groove, thereby achieving precise positioning and stable fixation, thereby ensuring the reliability and stability of the touch switch during use.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A container conveying device with a safety anti-pinch mechanism. By installing the safety anti-pinch mechanism on the side of the inspection platform, if an operator is tripped by the protruding locking component, the safety anti-pinch mechanism is triggered, immediately stopping the conveying mechanism from transporting the container, thus reducing the probability of the operator being injured by the container and the inspection platform.

[0027] 2. A rotating torsion spring is installed in the mounting seat for the safety plate, which helps to keep the safety plate in the first position when no external force is applied, thereby ensuring that the touch switch is in the open state and improving the reliability and safety of the system;

[0028] 3. By arranging a guide rail on the mounting plate, arranging a positioning groove on the guide rail, arranging a guide slider on the touch switch, and arranging a ball head spring plunger in the guide slider, the touch switch and the mounting plate are detachably connected, which is helpful for maintenance and replacement of the touch switch.

[0039] The following is combined with Figure 1-9 This application is described in further detail.

[0040] The embodiments of the present application disclose a container conveying device having a safety anti-pinch mechanism.

[0041] Reference Figure 2 A container conveying device with a safety anti-pinch mechanism includes a conveying mechanism 1, a detection platform 2 located on one side of the conveying mechanism 1, and a safety anti-pinch mechanism 3 mounted on the detection platform 2. The conveying mechanism 1 is a conveyor belt mounted on the ground and used to arrange rollers for containers 4. In this embodiment, the conveying direction of the conveying mechanism 1 is from left to right.

[0042] Reference Figure 2 and Figure 3 The inspection platform 2 includes a flat inspection plate 21 for an operator to stand on and flat support legs 22 for supporting the inspection plate 21. The bottom of the inspection plate 21 has a sliding gap 27 for the sliding arrangement of the locking assembly 42 of the container 4, which helps reduce the probability of the operator being tripped by the protruding locking assembly 42 of the container 4. The inspection platform 2 has a first side surface 23 perpendicular to the conveying direction of the conveyor mechanism 1 and close to the entrance of the conveyor mechanism 1, and a second side surface 24 opposite the first side surface 23. Both the first side surface 23 and the second side surface 24 of the inspection platform 2 are provided with a safety anti-pinch mechanism 3.

[0043] Reference Figure 4 and Figure 5The anti-pinch safety mechanism 3 includes a safety plate 31, a touch switch 32 mounted on the inspection platform 2 and electrically connected to the conveying mechanism 1, and a control link 33 connecting the touch switch 32 and the safety plate 31. When the touch switch 32 is on, the conveying mechanism 1 is ready for operation; when the touch switch 32 is off, the conveying mechanism 1 is inoperative. In other words, the touch switch 32 is connected in series to the control circuit of the conveying mechanism 1. The safety plate 31 includes a first straight plate 311 extending away from the inspection platform 2 and a second straight plate 312 connected to the end of the first straight plate 311 away from the inspection platform 2 and bent toward the inspection platform 2. To reduce the probability of the second straight plate 312 causing harm to the operator, a protective cover 34 is provided over the second straight plate 312 of the safety plate 31.

[0044] Reference Figure 4 and Figure 6 The detection platform 2 is provided with a mounting seat 25 for rotatably mounting a safety plate 31 on the first side 23 and the second side 24. After rotation, the safety plate 31 has a first position and a second position, and the second position is located on the side of the first position close to the detection platform 2. When the safety plate 31 is in the first position, the touch switch 32 is in the on state; when the safety plate 31 is in the second position, the touch switch 32 is in the off state. A rotating torsion spring 251 is also provided in the mounting seat 25 for driving the safety plate 31 to always have a tendency to be located in the first position. The safety anti-pinch mechanism 3 installed in the first side 23 has the same structure as the safety anti-pinch mechanism 3 installed in the second side 24, except that the direction in which the rotating torsion spring 251 in the mounting seat 25 drives the safety plate 31 to rotate is opposite to the direction in which the rotating torsion spring 251 in the second side 24 drives the safety plate 31 to rotate.

[0045] Reference Figure 4 and Figure 7 The first and second side surfaces 23 and 24 of the detection platform 2 are further provided with a mounting plate 26 for mounting a touch switch 32. The mounting plate 26 is provided with a guide rail 261. The touch switch 32 is provided with a guide slider 321 for engaging with the guide rail 261. The engagement between the guide rail 261 and the guide slider 321 enables a detachable connection between the touch switch 32 and the mounting plate 26, facilitating maintenance and replacement of the touch switch 32. The guide slot is a T-shaped slot, and the guide slider 321 is a T-shaped slider.

[0046] Reference Figure 7 and Figure 8In order to further stably fix the touch switch 32 arranged on the mounting plate 26, a positioning groove 2611 is provided on the guide rail 261, a plunger hole 3211 is provided on the guide slider 321, and a ball head spring plunger 3212 is provided in the plunger hole 3211. When the touch switch 32 is installed on the mounting plate 26, the plunger ball head of the ball head spring plunger 3212 is clamped in the positioning groove 2611.

[0047] Reference Figure 9 The control link 33 connects the safety plate 31 and the touch switch 32. The control link 33 has a first mounting post 331 and a second mounting post 332 at each end. The safety plate 31 has a mounting slot 313 on the first straight plate 311 for inserting the first mounting post 331. The touch switch 32 has a strip hole 322 on the touch rod for sliding the second mounting post 332. To reduce the possibility of the first and second mounting posts 331 and 332 being dislodged from the mounting slot 313 and strip hole 322, the control link 33 is provided with rubber sleeves 333 on the first and second mounting posts 331 and 332.

[0048] The implementation principle of a container conveying device with a safety anti-pinch mechanism in an embodiment of the present application is as follows: during normal transportation and maintenance of the container 4, the safety plate 31 of the safety anti-pinch mechanism 3 is in the first position, the touch switch 32 is in the on state, and the conveying mechanism 1 operates normally. When an operator is tripped by the protruding locking component 42 in the container 4, the operator's fall will drive the safety plate 31 to tilt toward the detection platform 2, so that the safety plate 31 is in the second position. By controlling the transmission of the connecting rod 33, the touch switch 32 is closed, and the conveying mechanism 1 stops conveying the container, thereby reducing the probability of the operator being pinched by the container 4 and the detection platform 2.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
