Description

Technical Field

[0001] The present application relates to luggage handling equipment, and in particular to a packaging device and an automatic sealing device. Background Art

[0002] To support the pilot program for the "preliminary machine inspection" inspection model for inbound checked baggage and the "image interpretation, classification and control, and focused supervision" approach, customs electronic locks (also known as active electronic locks) are required to mark checked baggage identified as suspicious through X-ray scanning and then seal it using an automatic sealing device. The automatic sealing device uses a strapping device, such as a strapping machine, to seal the suspected checked baggage with disposable flexible strapping and the customs electronic lock.

[0003] like Figure 1 As shown, the belt feeding motor 1 of the packaging equipment in the automatic sealing device of the related technology is arranged near the movement 3 below the frame 2 for conveying the flexible packaging belt. After the flexible packaging belt passes through the belt feeding wheel driven by the belt feeding motor 1, the road section it needs to travel includes 4 nearly 90° turns: the first turn A, the second turn B, the third turn C and the fourth turn D. It is easy for the belt feeding to get stuck and the belt cannot be delivered in place. The belt feeding success rate is about 95%. Figure 1 In the figure, the direction of the arrow is the moving direction of the flexible strapping tape.

[0004] The strapping machine in the automatic sealing device passes through four turns during the feeding process. This can easily cause the strap to get stuck in the final stage, leading to a strapping failure. Once a strapping jam occurs, it must be manually corrected. Since most airports are unmanned around the automatic sealing device, any malfunction requires immediate attention. This results in poor real-time handling, impacting the delivery of baggage for the entire flight and negatively impacting the passenger's customs clearance experience.

[0005] like Figure 2 As shown in the related art, the movement 3 includes an upper slider 31, a lower slider 32, and a slide rail base 33 with a slider receiving slot 33A. The upper slider 31 is slidably mounted on the slide rail base 33. The lower slider 32 is slidably connected below the upper slider 31 and positioned within the slider receiving slot 33A. When the flexible strapping tape 4 is delivered into position, a detection device detects the position of the strapping tape. Figure 2To facilitate illustration of the detection device, the rail base 33 schematically illustrates only the sidewalls 331 on either side, indicating their locations. The detection device comprises a paddle 91, a trigger rod 92, and a metal-sensing magnetic switch 93' serving as a detection element. The trigger rod 92 is positioned between the paddle 91 and the magnetic switch 93' and extends through the sidewall 331 of the rail base 33. The end of the trigger rod 92 closest to the paddle 91 faces the paddle 91. A nut 921 is mounted on the end of the trigger rod 92 closest to the magnetic switch 93'. The paddle 91 is mounted on the lower slider 32 through the opening 32A in the lower slider 32. Once the flexible strapping tape 4 is in place, the paddle 91 is triggered, pushing the trigger rod 92 along its length toward the magnetic switch 93'. The magnetic switch 93' detects the arrival of the flexible strapping tape 4 by detecting whether the nut on the trigger rod 92 reaches the sensing position of the magnetic switch 93'. Since the stroke of the trigger rod 92 is short and the trigger rod 92 cannot be guaranteed to move in only one direction during normal operation, there is a certain probability that the actual conveyor belt is in place during operation but the detection device cannot be triggered to output the in-place information.

[0006] The above statements are only used to provide background technical information related to the present application and do not necessarily constitute prior art. Summary of the Invention

[0058] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0059] In order to clearly illustrate the embodiments of the present application, in the description of the present application, Figure 2 The direction corresponding to the left and right directions in is called the left and right directions. Figure 2 The direction perpendicular to the paper is called the front-back direction, in which the direction entering the paper is the front, and the back is opposite to the front. Figure 2 The direction corresponding to the up-down direction is called the up-down direction.

[0060] like Figure 3 and Figure 4 As shown, the present application provides a packaging device for packaging articles, including a frame 2, a first belt feeding device, a second belt feeding device and a movement 3.

[0061] The frame 2 is annular and includes a belt groove for conveying a flexible strapping tape 4. A first belt feeder is disposed at a first position of the frame 2 and is configured to drive the flexible strapping tape 4 so that the flexible strapping tape 4 moves along the belt groove. A second belt feeder is disposed at a second position of the frame 2 spaced apart from the first position and is configured to drive the flexible strapping tape 4 so that the flexible strapping tape 4 moves along the belt groove. The movement 3 is located on the frame 2 and is configured to tighten the flexible strapping tape 4 around the outer periphery of the article after the head 41 of the flexible strapping tape 4 reaches the target position, cut the flexible strapping tape 4, and fuse the flexible strapping tape 4 into a belt loop.

[0062] The packaging equipment in the embodiment of the present application is provided with a first belt feeding device and a second belt feeding device. When conveying the flexible packaging belt 4, the first belt feeding device and the second belt feeding device work synchronously, which can achieve a more stable drive of the flexible packaging belt 4, facilitate the smooth conveying of the flexible packaging belt 4 into place, reduce the phenomenon of the flexible packaging belt 4 being stuck during conveying, and improve the success rate of conveying.

[0063] like Figure 3 As shown, in some embodiments of the packaging equipment, the second belt feeding device is located downstream of the first belt feeding device along the moving direction of the flexible strapping belt 4. When the second belt feeding device independently feeds the flexible strapping belt 4, the moving speed of the flexible strapping belt 4 is greater than or equal to the moving speed of the flexible strapping belt 4 when the first belt feeding device independently feeds the flexible strapping belt 4. Figure 3 In the figure, the direction of the arrow is the moving direction of the flexible strapping tape.

[0064] When the second belt feeding device is located downstream of the first belt feeding device, the moving speed of the flexible strapping belt 4 when the second belt feeding device independently feeds the flexible strapping belt 4 is equal to the moving speed of the flexible strapping belt 4 when the first belt feeding device independently feeds the flexible strapping belt 4, which is beneficial for stably feeding the flexible strapping belt 4 when the flexible strapping belt 4 is flat, thereby improving the success rate of belt feeding.

[0065] When the second belt feeding device is located downstream of the first belt feeding device, the moving speed of the flexible strapping belt 4 when the second belt feeding device independently feeds the flexible strapping belt 4 is greater than the moving speed of the flexible strapping belt 4 when the first belt feeding device independently feeds the flexible strapping belt 4, which is beneficial for the flexible strapping belt 4 located in the first belt feeding device and the second belt feeding device to be pulled by the second belt feeding device when the flexible strapping belt 4 is uneven, thereby facilitating the stable conveyance of the flexible strapping belt 4 under uneven conditions and improving the success rate of belt feeding.

[0066] In some embodiments of the packaging equipment, the first tape feeding device includes a first tape feeding motor 1 and a first tape feeding wheel driven by the first tape feeding motor 1, and the first tape feeding wheel is configured to contact the flexible packing tape 4 to drive the flexible packing tape 4 to move along the tape groove; and / or the second tape feeding device includes a second tape feeding motor 5 and a second tape feeding wheel driven by the second tape feeding motor 5, and the second tape feeding wheel is configured to contact the flexible packing tape 4 to drive the flexible packing tape 4 to move along the tape groove.

[0067] The first tape feeding device includes a first tape feeding motor 1 and a first tape feeding pulley driven by the first tape feeding motor 1, and / or the second tape feeding device includes a second tape feeding motor 5 and a second tape feeding pulley driven by the second tape feeding motor 5, so that the first tape feeding device and / or the second tape feeding device has a simple structure, is easy to control, and has a stable tape feeding effect.

[0068] like Figure 3 As shown, in some embodiments of the packaging device, the second tape feed device is located downstream of the first tape feed device along the moving direction of the flexible strapping belt 4. The first tape feed device includes a first tape feed motor 1 and a first tape feed pulley drivingly connected to the first tape feed motor 1; the second tape feed device includes a second tape feed motor 5 and a second tape feed pulley drivingly connected to the second tape feed motor 5; the rotation speed of the second tape feed pulley is greater than or equal to the rotation speed of the first tape feed pulley.

[0069] By making the rotation speed of the second tape feeding wheel greater than or equal to the rotation speed of the first tape feeding wheel, the moving speed of the flexible tape 4 when the second tape feeding device independently feeds the flexible tape 4 can be equal to the moving speed of the flexible tape 4 when the first tape feeding device independently feeds the flexible tape 4, which is beneficial for stably feeding the flexible tape 4 when the flexible tape 4 is flat, thereby facilitating the stable feeding of the flexible tape 4 and improving the success rate of tape feeding.

[0070] In some embodiments of the packaging device, along the moving direction of the flexible packaging belt 4, the distance between the first position and the second position is approximately half the length of the belt slot.

[0071] Along the moving direction of the flexible strapping belt 4, the distance between the first position and the second position is approximately half the length of the belt groove, which is conducive to making the conveying force borne by the first belt feeding device and the second belt feeding device less different, thereby facilitating the stable conveying of the flexible strapping belt 4 and improving the success rate of belt feeding.

[0072] like Figure 3 As shown, in some embodiments of the packaging device, the frame 2 is arranged vertically. The core 3 is located at the bottom of the frame 2, with the first position being at the bottom of the frame 2 and the second position being at the top of the frame 2.

[0073] The first position is located at the bottom of the frame 2. The second position is located at the top of the frame 2, so that the first belt feeding device and the second belt feeding device are separated by a large distance, and the path for conveying the flexible strapping belt 4 from the first belt feeding device to the second belt feeding device includes two turns, and the path for conveying the flexible strapping belt 4 from the second belt feeding device to the first belt feeding device includes two turns, which is beneficial for the first belt feeding device and the second belt feeding device to have a small difference in conveying force, thereby facilitating the stable conveying of the flexible strapping belt 4 and improving the success rate of belt feeding.

[0074] like Figures 5 to 8 As shown, in some embodiments of the packaging device, the movement 3 includes an upper slider 31, a lower slider 32 and a slide base 33 with a slider accommodating groove 33A, the upper slider 31 is slidably mounted on the slide base 33, and the lower slider 32 is slidably connected to the bottom of the upper slider 31 and is located in the slider accommodating groove 33A. The packaging device also includes a detection device, which is configured to detect the arrival information of the head 41 of the flexible packaging tape 4 at the target position. The detection device includes a first detection part and a second detection part. The first detection part is arranged outside the slide base 33 and is configured to detect the first information that the head 41 of the flexible packaging tape 4 has arrived at the target position. The arrival information includes the first information. The second detection part is arranged inside the slider accommodating groove 33A and is configured to detect the second information that the head 41 of the flexible packaging tape 4 has arrived at the target position. The arrival information includes the second information.

[0075] Two detection parts are used to detect the first information and the second information respectively. The first information and the second information are detected at different positions and verify each other, which is beneficial to improving the accuracy of the information of the head 41 of the flexible strapping belt 4 reaching the target position.

[0076] like Figures 5 to 8As shown, in some embodiments of the packaging device, the detection device also includes a paddle 91 located within the slider accommodating groove 33A and a trigger rod 92 that passes through the side wall 331 of the slide rail base 33 and is movable relative to the side wall 331. The first detection unit is mounted on the outside of the side wall 331 of the slide rail base 33 and obtains first information by detecting the movement of the trigger rod 92 after the paddle 91 is triggered by the strap head 41 of the flexible strapping strap 4 and then the paddle 91 triggers the trigger rod 92. The second detection unit is mounted on the lower slider 32 and obtains second information by detecting the movement of the paddle 91 after the paddle 91 is triggered by the strap head 41 of the flexible strapping strap 4.

[0077] The second detection part is directly triggered by the action of the paddle 91 without going through the trigger rod 92, thereby reducing the information transmission links, especially reducing the information transmission link of the trigger rod 92 which is most likely to cause detection errors, thereby helping to improve the accuracy of the arrival information of the head 41 of the flexible strapping tape 4 at the target position detected by the second detection part.

[0078] In some embodiments of the packaging device, the first detection part includes a first microswitch 93, and the end faces of the trigger rod 92 at both ends are opposite to the paddle 91 and the first trigger piece 93A of the first microswitch 93, respectively; and / or the second detection part includes a second microswitch 95, and the detection device also includes a touch piece 94, which is fixedly arranged relative to the paddle 91, and the touch piece 94 is opposite to the second trigger piece 95A of the second microswitch 95.

[0079] The end faces of the trigger rod 92 at both ends are respectively opposite to the paddle 91 and the first trigger piece 93A of the first micro switch 93, which helps the trigger rod 92 to accurately transmit the movement of the paddle 91 to the first trigger piece 93A of the first micro switch 93, thereby helping to reduce and improve the accuracy of the second detection part in detecting the first information.

[0080] The touch member 94 is fixedly arranged relative to the paddle 91, and the touch member 94 is opposite to the second trigger piece 95A of the second micro switch 95. As long as the paddle 91 moves, the touch member 94 will move accordingly and trigger the second trigger piece 95A of the second micro switch 95, thereby helping to improve the accuracy of the second detection unit in detecting the first information.

[0081] The trigger 94 and the paddle 91 can be integrally provided, for example, they can be formed by cutting and bending the same metal sheet. The trigger 94 and the paddle 91 can also be separately provided and then fixedly connected together.

[0082] In some embodiments of the packaging device, the relative position of the first microswitch 93 and the trigger rod 92 can be adjusted so that the first trigger piece 93A is opposite to the end face of the trigger rod 92; and / or the relative position of the second microswitch 95 and the trigger member 94 can be adjusted so that the second trigger piece 95A is opposite to the trigger member 94.

[0083] This arrangement facilitates that after the head 41 of the flexible strapping tape 4 triggers the paddle 91, the trigger rod 92 accurately transmits the action of the paddle 91 to the first trigger piece 93A, thereby allowing the first micro switch 93 to obtain the first information and / or the trigger member 94 accurately transmits the action of the paddle 91 to the second trigger piece 95A, thereby allowing the second micro switch 95 to obtain the second information. This facilitates improving the accuracy of obtaining the in-position information.

[0084] The present invention also provides an automatic sealing device for sealing articles, including the packaging equipment of the present invention. The automatic sealing device has the advantages of the packaging equipment of the present invention.

[0085] The following combination Figures 3 to 8 The packaging device of this embodiment is described.

[0086] like Figure 3 and Figure 4 As shown, the packaging device of the embodiment of the present application includes a frame 2, a first belt feeding device, a second belt feeding device, a movement 3 and a detection device.

[0087] The frame 2 is annular and vertically arranged. The core 3 is located at the bottom of the frame 2. The frame 2 includes a belt groove for conveying a flexible strapping belt 4.

[0088] The first belt feed device is disposed at a first position of the frame 2, the first position being located at the bottom of the frame 2, next to the movement 3. The first belt feed device is configured to drive the flexible strapping belt 4 so that the flexible strapping belt 4 moves along the belt groove. The first belt feed device includes a first belt feed motor 1 and a first belt feed pulley drivingly connected to the first belt feed motor 1. The first belt feed pulley is configured to contact the flexible strapping belt 4 to drive the flexible strapping belt 4 to move along the belt groove.

[0089] The second tape feeding device is arranged at a second position of the frame 2 spaced apart from the first position. Figure 3 and Figure 4 As shown, the second position is located at the top of the frame 2, so that the flexible packing belt 4 moves in the direction ( Figure 3 The distance between the first position and the second position is approximately half the length of the belt slot. The second belt feed device is configured to drive the flexible strapping strap 4 to move along the belt slot. The second belt feed device is located downstream of the first belt feed device in the direction of movement of the flexible strapping strap 4.

[0090] When the second belt feeding device independently feeds the flexible strapping belt 4, the moving speed of the flexible strapping belt 4 is greater than or equal to the moving speed of the flexible strapping belt 4 when the first belt feeding device independently feeds the flexible strapping belt 4.

[0091] When the second belt feeding device is located downstream of the first belt feeding device, the moving speed of the flexible strapping belt 4 when the second belt feeding device independently feeds the flexible strapping belt 4 is greater than the moving speed of the flexible strapping belt 4 when the first belt feeding device independently feeds the flexible strapping belt 4, which is beneficial for the flexible strapping belt 4 located in the first belt feeding device and the second belt feeding device to be pulled by the second belt feeding device when the flexible strapping belt 4 is uneven, thereby facilitating the stable conveyance of the flexible strapping belt 4 under uneven conditions and improving the success rate of belt feeding.

[0092] The second tape feeding device includes a second tape feeding motor 5 and a second tape feeding wheel connected to the second tape feeding motor 5, and the second tape feeding wheel is configured to contact the flexible strapping belt 4 to drive the flexible strapping belt 4 to move along the belt groove. Figure 4 As shown, the second belt feed motor 5 is mounted on a mounting bracket 6 fixedly connected to the side of the frame 2. The second belt feed pulley is located in the belt slot of the frame 2. The rotating shaft of the second belt feed motor 5 passes through the groove wall of the belt slot and is connected to the second belt feed pulley. The wheel surface of the second belt feed pulley presses against the surface of the flexible strapping tape 4, thereby conveying the flexible strapping tape 4 through friction.

[0093] In this embodiment, the first tape feeding device and the second tape feeding device have similar structures and working principles.

[0094] The rotation speed of the second tape feed wheel is greater than the rotation speed of the first tape feed wheel, so that the moving speed of the flexible tape 4 when the second tape feed device independently feeds the flexible tape 4 is greater than the moving speed of the flexible tape 4 when the first tape feed device independently feeds the flexible tape 4.

[0095] The movement 3 is located on the frame 2 and is configured to tighten the flexible strapping belt 4 around the periphery of the article after the head 41 of the flexible strapping belt 4 reaches the target position, cut the flexible strapping belt 4, and weld the flexible strapping belt 4 into a belt ring.

[0096] like Figure 3 As shown, in this embodiment, when items need to be packaged, the items are transported to the ring of the annular frame 2, and the flexible packaging belt 4 on the pulley (not shown) first moves to the left from the first belt feeding device under the drive of the first belt feeding device, passes the first corner A, and moves upward toward the second corner B. After passing the second corner B, it moves to the right and passes the second belt feeding device and continues to move toward the third corner C under the drive of the second belt feeding device. After passing the third corner C, it moves downward toward the fourth corner D. After passing the fourth corner D, it moves to the left. After the belt head 41 reaches the target position in the movement 3, the movement 3 tightens the flexible packaging belt 4 to the outer periphery of the item, cuts the flexible packaging belt 4, and welds the flexible packaging belt 4 into a belt ring to complete an item packaging action.

[0097] like Figures 5 to 8As shown, the movement 3 includes an upper slider 31, a lower slider 32 and a slide rail base 33 with a slider receiving groove 33A. The upper slider 31 is slidably mounted on the slide rail base 33 in the front-to-back direction. The left and right ends of the upper slider 31 are mounted in the base slide grooves extending in the front-to-back direction on the upper part of the two side walls 331 of the slide rail base 33. The lower slider 32 is slidably connected to the bottom of the upper slider 31 in the front-to-back direction and is located in the slider receiving groove 33A. The left and right ends of the lower slider 32 are mounted in the upper slider slide grooves extending in the front-to-back direction on the left and right ends of the upper slider 31. The lower slider 32 can follow the upper slider 31 to move relative to the slide rail base 33 in the front-to-back direction when there is no obstruction, and can move relative to the upper slider 31 in the front-to-back direction when there is an obstruction.

[0098] The detection device is configured to detect the arrival of the head 41 of the flexible strapping tape 4 at the target position. The detection device includes a paddle 91, a trigger rod 92, a first micro switch 93 as a first detection part, and a second micro switch 95 as a second detection part.

[0099] The first detection portion is mounted on the outer side of the left side wall 331 of the rail base 33. The second detection portion is mounted on the lower slider 32.

[0100] The paddle 91 is located within the slider receiving groove 33A. The paddle 91 is installed on the lower slider 32 through the opening 32A therein. Once the flexible strap 4 is in place, the paddle 91 is triggered to operate. A trigger rod 92 is installed on the slide rail base 33 through the side wall 331 thereof. The trigger rod 92 is located between the paddle 91 and the first microswitch 93. The end of the trigger rod 92, which is closest to the paddle 91, faces the paddle 91. The side of the trigger rod 92, which is closest to the first microswitch 93, faces the first triggering piece 93A of the first microswitch 93.

[0101] The first micro switch 93 is configured to detect first information that the tape head 41 of the flexible strapping tape 4 reaches the target position, and the arrival information of the tape head 41 of the flexible strapping tape 4 at the target position includes the first information.

[0102] The first micro switch 93 is mounted on the outer side of the side wall 331 of the slide rail base 33 through the first fixing bracket 96 matched therewith. The relative position of the first micro switch 93 and the trigger rod 92 is adjustable so that the first trigger piece 93A is opposite to the end face of the trigger rod 92. Figures 5 to 8As shown, the first fixing frame 96 includes a first frame body 961 and a second frame body 962. The first frame body 961 has a first oblong hole 961A. The second frame body 962 has a second oblong hole 962A. The second frame body 962 is connected to the outer side of the side wall 331 of the slide rail base 33 via bolts passing through the second oblong hole 962A. The first frame body 961 is connected to the second frame body 962 via bolts passing through the first oblong hole 961A. The first micro switch 93 is mounted on the first frame body 961. The second oblong hole 962A extends perpendicularly to the first oblong hole 961A. By adjusting the relative position of the second oblong hole 962A and the bolt that cooperates therewith, and / or adjusting the relative position of the first oblong hole 961A and the bolt that cooperates therewith, the position of the first microswitch 93 relative to the trigger rod 92 can be adjusted so that the position of the first trigger piece 93A is aligned with the end face of the corresponding end of the trigger rod 92, thereby improving the accuracy of the first microswitch 93 in obtaining the first information.

[0103] The first micro switch 93 obtains the first information by detecting the action of the trigger lever 92 when the head 41 of the flexible strapping belt 4 triggers the paddle 91 and then the paddle 91 triggers the trigger lever 92 .

[0104] like Figures 5 to 8 As shown, when the paddle 91 is triggered by the lead 41 and moves, the paddle 91 pushes the trigger rod 92 to move along its length toward the direction of the first micro switch 93 (from right to left in this embodiment), so that the end face of the trigger rod 92 contacts the first trigger piece 93A, and the first micro switch 93 can detect the first information.

[0105] The second micro switch 95 is configured to detect second information indicating that the tape head 41 of the flexible strapping tape 4 has reached the target position. The arrival information of the tape head 41 of the flexible strapping tape 4 at the target position includes the second information. The detection device further includes a trigger 94, which is integrally formed with the paddle 91. The trigger 94 is opposite to the second trigger piece 95A of the second micro switch 95.

[0106] The second microswitch 95 is mounted below the lower slider 32 via a second mounting bracket 97. The second microswitch 95 can be adjusted relative to the trigger 94 so that the second trigger piece 95A is opposite the trigger 94. When the relative position of the second microswitch 95 and the trigger 94 is adjustable, the second mounting bracket 97 can have a structure similar to that of the first mounting bracket 96, and further description thereof will not be given here.

[0107] The second micro switch 95 triggers the paddle 91 by detecting the head 41 of the flexible strapping tape 4. The movement of the paddle 91 drives the touch piece 94. The touch piece 94 moves toward the second micro switch 95 (from left to right in this embodiment) to trigger the second trigger piece 95A. The second micro switch 95 can obtain the second information.

[0108] like Figure 8 As shown, in this embodiment, the portion of the paddle 91 below the lower slider 32 is mounted on a connecting shaft 98 and is rotatable relative to the connecting shaft 98. A trigger lever 92 and a contact element 94 are located on the left and right sides of the paddle 91, respectively. In the front-to-back direction, the first microswitch 93 and the trigger lever 92 are located behind the connecting shaft 98, while the second microswitch 95 and the contact element 94 are located in front of the connecting shaft 98. The portion of the paddle 91 above the lower slider 32 is located behind the connecting shaft 98. When the belt head 41 moves from right to left and reaches the target position, it contacts the portion of the paddle 91 above the lower slider 32, causing the paddle 91 to rotate about the connecting shaft 98. The portion of the paddle 91 below the lower slider 32 and behind the connecting shaft 98 moves leftward, contacting the trigger lever 92, thereby triggering the first microswitch 93. Simultaneously, the contact element 94 located behind the connecting shaft 98 moves rightward under the action of the paddle 91, triggering the second microswitch 95.
