Protection device and edge sealing equipment

Abstract

The utility model discloses a protection device and edge sealing equipment. The protection device comprises a first bearing piece, a protection switch and a moving piece. The first bearing part is suitable for bearing the materials output to the first bearing part by the output part; the protection switch is suitable for enabling the output piece to stop working when being triggered; the moving part is located at the tail end of the first bearing part, and the moving part is suitable for stopping at the first position and moving in the direction close to the protection switch when the thrust of the materials is larger than a first threshold value till the moving part triggers the protection switch. In the using process, when materials are stacked on the first bearing piece, a plate output by the output piece collides with the plate, close to the output piece, on the first bearing piece, and due to the fact that the speed is high and inertia is large when the output piece outputs the materials, thrust of the plate to the moving piece is suddenly increased and exceeds a first threshold value; therefore, the moving part moves in the direction close to the protection switch until the protection switch is triggered, the protection switch enables the output part or the whole protection device to stop acting, and danger caused by material accumulation is prevented.

Description

Technical Field

[0001] The utility model relates to the field of plate production equipment, in particular to a protective device and edge sealing equipment. Background Art

[0002] In the existing edge banding equipment, the edge banding machine transports the edge-banded panels to the conveyor belt, and the conveyor belt transfers the panels. When multiple panels pass through the conveyor belt closely one after the other, panel accumulation may occur. At this time, if the equipment does not stop, when the edge banding machine outputs the next panel, the panel will hit the panel on the conveyor belt close to the edge banding machine. Since the edge banding machine outputs panels at a fast speed and has a large inertia, the kinetic energy of the panel farthest from the edge banding machine will also increase, which can easily damage the equipment or cause personal danger. If the equipment cannot be shut down in time at this time, the loss will be further expanded. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and to provide a protective device and an edge sealing device.

[0004] To achieve the above objectives, the present invention and its preferred embodiments adopt the following technical solutions, but the embodiments are not limited to the following solutions:

[0005] Solution 1: A protective device, adapted to prevent danger caused by materials outputted by an output member in a first direction, comprising a first carrier adapted to receive materials outputted thereon by the output member;

[0007] The moving part is located at the end of the first bearing member, is suitable for stopping at a first position, and moves in a direction close to the protection switch when the thrust of the material is greater than a first threshold value until the moving part triggers the protection switch.

[0008] Solution 2, based on Solution 1, further includes a damping member, which is suitable for applying a force to the moving member so that the moving member stops at a first position when the thrust of the material is less than or equal to a first threshold.

[0009] Solution three, based on solution two, the damping member is a cylinder, an elastic member or mutually repelling magnets.

[0010] Solution 4: Based on Solution 1, the moving part is suitable for sliding or rotating to trigger the protection switch.

[0011] Solution five, based on solution one, the first carrier is suitable for transporting the material thereon along the first direction.

[0012] Solution six, based on solution one, further includes a second carrier and a pushing member, wherein the pushing member is suitable for pushing the material on the first carrier to the second carrier.

[0013] Option seven, based on option six, also includes a sensor, which is suitable for sensing whether there is material along the second direction to determine whether the material interferes with the first carrier or the second carrier when the pushing member pushes the material. The pushing member is suitable for pushing the material when the sensor determines that there is no interference.

[0014] Solution eight, based on solution six, the second carrier is suitable for transporting the material thereon along a second direction intersecting with the first direction.

[0015] Option 9, an edge banding device, comprising an output component and a protective device as described in any one of Options 1 to 8, wherein the output component is an edge banding machine.

[0016] Solution 10: Based on Solution 9, the protection switch is suitable for shutting down the edge banding equipment when triggered.

[0017] From the above description of the present invention and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0018] 1. Solution 1 and its preferred embodiment, a protective device, which is suitable for preventing dangers caused by materials outputted by an output member along a first direction, includes a first bearing member, a protective switch, and a moving member.

[0019] The first carrier is suitable for receiving the material outputted thereto by the output member; the protection switch is suitable for stopping the output member from working when triggered; the moving member is located at the end of the first carrier, the moving member is suitable for docking at a first position, and moves in a direction close to the protection switch when the thrust of the material is greater than a first threshold value until the moving member triggers the protection switch.

[0020] During use, when material accumulates on the first carrier, the plate member discharged by the output member will impact the plate member on the first carrier that is adjacent to the output member. Due to the high speed and high inertia of the output member when discharging material, the thrust of the plate member on the moving member suddenly increases and exceeds a first threshold, causing the moving member to move toward the protective switch until the protective switch is triggered. The protective switch then stops the output member or the entire protective device, preventing danger caused by material accumulation. The moving member is adapted to rest in the first position, preventing it from easily moving and triggering the protective switch during normal use.

[0021] 2. In Option 2 and its preferred embodiment, the damping element is adapted to apply a force to the moving element, causing it to rest at a first position when the thrust of the material is less than or equal to a first threshold. Consequently, when the protection condition is not met, the moving element automatically returns to or remains in the first position, preventing movement of the moving element due to machine vibration or thrust from the plate during normal use. Furthermore, when the protection condition is met and the moving element moves, a certain degree of cushioning is achieved.

[0022] 3. In scheme three and its preferred embodiment, the damping member is a cylinder, an elastic member or mutually repelling magnets. The cylinder can adjust the value of the first threshold according to the air pressure.

[0023] 4. In the fourth solution and its preferred embodiment, the moving part is suitable for sliding or rotating to trigger the protection switch, and the corresponding movement is easy to achieve.

[0024] 5. In solution five and its preferred embodiment, the first carrier is suitable for conveying the material thereon in a first direction, so that the material can be conveyed to other locations, reducing material accumulation and increasing the degree of automation.

[0025] 6. In the sixth solution and its preferred embodiment, the pushing member is suitable for pushing the material on the first carrier to the second carrier, thereby reducing the possibility of material accumulation on the first carrier.

[0026] 7. In Option 7 and its preferred embodiment, the sensor is suitable for sensing whether there is material along the second direction to determine whether the material interferes with the first carrier or the second carrier when the pushing member pushes the material. The pushing member is suitable for pushing the material when the sensor determines that there is no interference, thereby protecting the first carrier or the second carrier or the material.

[0027] 8. In solution eight and its preferred embodiment, the second carrier is suitable for transporting the material thereon along a second direction intersecting with the first direction, so that the material can be transported to other locations, reducing material accumulation and increasing the degree of automation.

[0028] 9. In the ninth solution and its preferred embodiment, an edge banding device includes an output component and the above-mentioned protective device, and the output component is an edge banding machine, thus having the beneficial effects brought by the above-mentioned protective device.

[0029] 10. In the tenth solution and its preferred embodiment, the protection switch is suitable for shutting down the edge banding equipment and the entire equipment when triggered, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In the claims, description and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0045] refer to Figure 1-Figure 5 A protective device is provided for preventing hazards caused by materials being delivered by an output member in a first direction 8. The protective device may be used in edge banding equipment, where the output member is an edge banding machine. Of course, in other embodiments, the protective device may also be used in other equipment, such as packaging lines, where the output member is adapted to deliver packaged products.

[0046] refer to Figure 1 The protection device includes a first bearing member 1, a protection switch 2, a moving member 3, a damping member 4, a second bearing member 5, and a pushing member 6.

[0047] refer to Figure 1 、 Figure 2 In this embodiment, the output part is an edge banding machine, which performs edge banding on the plate, and the output part is suitable for outputting the edge-banded material along the first direction 8. The first direction 8 is as follows: Figure 2 shown.

[0048] The first carrier 1 is suitable for receiving materials outputted onto the first carrier 1 by the output member. In this embodiment, the first carrier 1 is also suitable for conveying panels thereon along the first direction 8. The first carrier 1 is a conveyor belt.

[0049] refer to Figure 3The protection switch 2 is suitable for stopping the output part or the entire protection device when it is triggered. Preferably, when the protection switch 2 is triggered, the power elements of the entire edge banding equipment are shut down, and the power elements include the first carrier 1, the second carrier 5 and the output part, etc.

[0050] The moving member 3 is located at the end of the first carrier 1, which is the side of the first carrier 1 away from the output member. The moving member 3 is adapted to rest at a first position and, when the thrust of the plate exceeds a first threshold, move toward the protective switch 2 until the moving member 3 triggers the protective switch 2. The method of triggering the protective switch 2 depends on the type of protective switch 2. If the protective switch 2 is mechanical, the moving member 3 may trigger the protective switch 2 by contacting the protective switch 2. If the protective switch 2 is sensor-based, the moving member 3 may trigger the protective switch 2 by blocking or dislodging the sensor path. In this embodiment, the moving member 3 is adapted to slide or rotate to trigger the protective switch 2. In the scenario of this embodiment, when multiple panels pass closely together through the first carrier 1, panel accumulation occurs. If the device does not stop at this time, when the output member outputs the next panel, it will collide with the panel on the first carrier 1 that is closest to the output member. Because the output member outputs the panel at a high speed and has greater inertia (the thrust on the panel is greater than that on the first carrier 1), the thrust of the panel on the moving member 3 suddenly increases and exceeds the first threshold, causing the moving member 3 to move in a direction closer to the protective switch 2. In this embodiment, the moving member 3 is adapted to slide in the first direction 8 to trigger the protective switch 2.

[0051] refer to Figure 3 The damping member 4 is suitable for applying a force to the moving member 3 so that the moving member 3 stops at the first position when the thrust of the plate is less than or equal to the first threshold value, preventing the moving member 3 from triggering the protection switch 2 under normal circumstances. For example, when the first carrier 1 normally transports the plate, the plate also generates a thrust on the moving member 3 under the action of the transmission of the first carrier 1. At this time, the thrust of the plate should prevent the moving member 3 from moving, or although it causes the moving member 3 to move, the moving member 3 cannot move to trigger the protection switch 2.

[0052] The damping member 4 is a cylinder, an elastic member or mutually repelling magnets. When the damping member 4 is a cylinder, the output end of the cylinder is fixedly connected to the moving member 3, and the cylinder body is installed on the frame (which can be the frame of the first supporting member 1 or can be installed separately). When the damping member 4 is an elastic member, the two ends of the elastic member act on the moving member 3 and the frame respectively. When the damping member 4 is a mutually repelling magnet, one magnet is installed on the moving member 3 and the other is installed on the frame. The cylinder can adjust the value of the first threshold value according to the air pressure. Similarly, by changing the compression of the elastic member and the distance between the two mutually repelling magnets, the same effect can be achieved. A certain buffering can also be achieved by the damping member 4, so that when the protective switch 2 is contact-type, the possibility of the moving member 3 damaging the protective switch 2 can be reduced. In this embodiment, the damping member 4 is a cylinder.

[0053] refer to Figure 2 The second carrier 5 is adapted to transport the panels thereon along a second direction 9 intersecting the first direction 8. The second carrier 5 is connected to the end of the first carrier 1 and is used to transfer the panels on the first carrier 1 to ensure the continued operation of the first carrier 1. The second carrier 5 may also be a conveyor belt. The second carrier 5 is located at the end of the first carrier 1.

[0054] refer to Figure 1 、 Figure 2 The pushing member 6 is suitable for pushing the plate on the first supporting member 1 to the second supporting member 5.

[0055] refer to Figure 2 、 Figure 4 、 Figure 5 , the sensor 7 is adapted to sense whether there is a plate along the second direction 9, so as to determine whether the plate interferes with the first carrier 1 or the second carrier 5 when the pusher 6 pushes the plate. The sensor 7 can be a set of beam sensors, one for emitting light and the other for receiving light. In other embodiments, the sensor 7 can also be a distance sensor, etc. In the first direction 8, as Figure 6 , when the sensor 7 is located at the front end of the pusher 6, when the sensor 7 changes from sensing the plate to not sensing the plate, it can be regarded as non-interference; Figure 7 When sensor 7 is located at the end of pusher 6 and sensor 7 switches from not sensing the panel to sensing the panel, it is considered non-interference. Whether or not interference exists can be determined based on the actual installation situation. Pusher 6 only operates to push the panel when sensor 7 determines there is no interference, ensuring safety. In this embodiment, sensor 7 is a through-beam sensor.

[0056] During use, when abnormal material accumulation occurs, the thrust of the plate on the moving part 3 suddenly increases and exceeds the first threshold, causing the moving part 3 to move in the direction close to the protection switch 2 and triggering the protection switch 2 to shut down the equipment.

[0057] Compared with the prior art, this embodiment has the following beneficial effects:

[0058] In an exemplary embodiment, a protective device is provided, which is suitable for preventing danger caused by materials outputted by an output member along a first direction 8 , and includes a first carrier 1 , a protective switch 2 , and a moving member 3 .

[0059] The output member is suitable for outputting materials along a first direction 8; the first carrier 1 is suitable for receiving materials outputted thereto by the output member; the protection switch 2 is suitable for stopping the output member from working when triggered; the moving member 3 is located at the end of the first carrier 1, and the moving member 3 is suitable for docking at a first position and moving in a direction close to the protection switch 2 when the thrust of the material is greater than a first threshold value until the moving member 3 triggers the protection switch 2.

[0060] During use, when material accumulates on the first carrier 1, the plate delivered by the output element will impact the plate adjacent to the output element on the first carrier 1. Due to the high speed and high inertia of the output element when delivering material, the thrust of the plate on the moving element 3 suddenly increases and exceeds a first threshold, causing the moving element 3 to move toward the protective switch 2 until the protective switch 2 is triggered. The protective switch 2 then stops the output element or the entire protective device, preventing the danger caused by material accumulation. The moving element 3 is adapted to be parked in the first position, preventing it from easily moving and triggering the protective switch 2 during normal use.

[0061] In one exemplary embodiment, the damping element 4 is adapted to apply a force to the moving element 3, causing the moving element 3 to stop at a first position when the thrust of the material is less than or equal to a first threshold. Consequently, when the protection condition is not met, the moving element 3 can automatically return to or remain in the first position, preventing movement of the moving element 3 due to machine vibration or thrust from the plate during normal use. Furthermore, when the protection condition is met and the moving element 3 moves, a certain degree of cushioning is achieved.

[0062] In an exemplary embodiment, the damping member 4 is a cylinder, an elastic member or mutually repelling magnets. The cylinder can adjust the value of the first threshold according to the air pressure. The same effect can be achieved by changing the compression of the elastic member and the distance between the two mutually repelling magnets.

[0063] In an exemplary embodiment, the moving part 3 is suitable for sliding or rotating to trigger the protection switch 2, and is easy to achieve corresponding movement.

[0064] In an exemplary embodiment, the first carrier 1 is suitable for conveying the material thereon along the first direction 8, so that the material can be conveyed to other locations, thereby reducing material accumulation and increasing the degree of automation.

[0065] In an exemplary embodiment, the pushing member 6 is adapted to push the material on the first carrier 1 onto the second carrier 5 , thereby reducing the possibility of material accumulation on the first carrier 1 .

[0066] In an exemplary embodiment, the sensor 7 is suitable for sensing whether there is material along the second direction 9 to determine whether the material interferes with the first carrier 1 or the second carrier 5 when the pushing member 6 pushes the material. The pushing member 6 is suitable for pushing the material when the sensor 7 determines that there is no interference, thereby protecting the first carrier 1 or the second carrier 5 or the material.

[0067] In an exemplary embodiment, the second carrier 5 is suitable for conveying the material thereon along a second direction 9 intersecting with the first direction 8, so that the material can be conveyed to other locations, reducing material accumulation and increasing the degree of automation.

[0068] In an exemplary embodiment, an edge banding device includes an output member and the above-mentioned protective device, and the output member is an edge banding machine, thereby having the beneficial effects brought by the above-mentioned protective device.

[0069] In an exemplary embodiment, the protection switch 2 is adapted to shut down the edge banding device and the entire device when triggered, thereby making the device safer.
