Description

Technical Field

[0001] This utility model relates to the field of bag and luggage processing, specifically to bag and luggage processing equipment. Background Technology

[0002] The vacuum forming process for bags is relatively mature, consisting of a heating station and a forming station. The heating station is equipped with a heating furnace, while the forming station has forming molds, a clamping frame structure, and a trimming knife. A moving frame holding the sheet material moves between the forming station and the heating station. Traditional vacuum forming equipment for bags has the following problems: First, the upper frame of the moving frame is driven by a cylinder. Since gas is compressible, the clamping frame structure must hold the upper frame down during vacuum forming to maintain a tight seal between the upper and lower frames; this structure is complex and occupies valuable operating space in the forming station. Second, the trimming and vacuum forming processes share a single station, resulting in low production efficiency. Third, the trimming knife requires a moving component to move relative to the finished product, leading to congestion in the forming station and limiting the space available for sheet material loading and finished product removal. Utility Model Content

[0003] In view of the technical problems existing in the background art, the technical problem to be solved by this utility model is to provide a bag processing equipment with reasonable structural design and high production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This bag processing equipment is characterized by comprising a forming mechanism, a heating mechanism, an edge trimming mechanism, and a robotic arm; the bag processing equipment is provided with a forming station, a heating station, and an edge trimming station.

[0005] The forming station and the heating station are arranged adjacent to each other, and the forming mechanism includes a movable frame that can move laterally between the forming station and the heating station.

[0006] The trimming mechanism is located at the trimming station and to the side of the forming station, and the trimming mechanism includes a laser cutting head.

[0007] The robotic arm is equipped with a suction device, which drives the suction device to deliver the formed product from the forming station to the trimming station, and the suction device rotates relative to the laser cutting head.

[0008] This utility model features a compact structure with short travel distances between mechanisms. The robotic arm directly delivers the product from the forming station to the trimming station for trimming operations, resulting in a compact structure and high efficiency. Simultaneously, a suction device is used to hold the formed bag, and the robotic arm rotates the bag relative to the laser cutting head. As the bag rotates, the laser cutting head removes excess material, achieving trimming and punching.

[0009] Preferably, the suction component is a suction cup, and several suction cups are provided and mounted on a movable frame, which is connected to a robotic arm. This increases the coverage area of ​​the suction cups, allowing for stable adsorption of the shaped bags.

[0010] Preferably, the robotic arm is a six-axis robotic arm;

[0011] The robotic arm includes a base, a first arm, a second arm, a first connecting seat, a second connecting seat, and a connecting head. The first connecting seat is rotatably connected to the base via a first vertical axis. The first arm is rotatably connected to the first connecting seat via a first horizontal axis. The second connecting seat is rotatably connected to the first arm via a second horizontal axis. The second arm is rotatably connected to the second connecting seat via a first vertical axis. The connecting head is rotatably connected to the second arm via a third horizontal axis. The moving frame is rotatably connected to the connecting head via a second vertical axis. The robotic arm can achieve omnidirectional movement and rotation of the moving frame, and can move and rotate the adsorbed bags relative to the laser cutting head. The laser cutting head remains stationary during operation. As the bags move and rotate, the laser cutting head removes excess waste material from the bags, achieving trimming and punching.

[0012] Preferably, the movable frame includes a base frame and a pressure plate.

[0013] The pressure plate is provided in four pieces, which correspond to the four sides of the bottom frame and are swayed on the bottom frame. The four sides of the bottom frame that are pressed together with the pressure plate are provided with sealing strips.

[0014] When the four pressure plates are pressed together with the four sides of the bottom frame, the four pressure plates form a square that is closed on all four sides.

[0015] This invention uses four pressure plates pressed against the bottom frame to seal and fix the sheet material around its perimeter. The four pressure plates occupy little space, leaving ample operating space at the forming station. Compared to the prior art, the structure is more compact and streamlined, making the forming station more operable. The sealing strip ensures a tight seal between the pressure plates and the bottom frame, preventing air leakage during vacuum forming.

[0016] Preferably, the two ends of the pressure plate are rotatably mounted on the bottom frame via a rotating shaft. The outward-facing side of the pressure plate in a horizontal state is connected to an upwardly inclined drive arm. The drive arm is connected to a first transmission component that drives the pressure plate to swing. The first transmission component is mounted on the bottom frame.

[0017] The first transmission component pulls down the drive arm to make the pressure plate swing outward, and pushes the drive arm upward to make the pressure plate swing inward and press against the bottom frame. The upward tilting drive arm swings at a larger angle than the horizontal drive arm, resulting in a larger rotation angle of the pressure plate, which provides sufficient space for loading and unloading operations.

[0018] Preferably, the first transmission component includes a linear electric cylinder, a lifting seat, a connecting rod, and a guide column. The linear electric cylinder and the guide column are mounted on the base frame. The lifting seat is connected to the lead screw of the linear electric cylinder. The two ends of the connecting rod are rotatably connected to the pressure plate and the lifting seat, respectively. The linear electric cylinder drives the lifting seat to move up and down along the guide column. During vacuum forming, the linear electric cylinder has a self-locking function to prevent retraction, provides excellent clamping effect, and eliminates the need for additional components to apply pressure, resulting in a large operating space above the forming station.

[0019] Preferably, the first transmission component is provided in two sets, and one set of the first transmission component drives two adjacent pressure plates to swing.

[0020] The two adjacent pressure plates are designated as the first pressure plate and the second pressure plate, respectively. The connecting rod is divided into a first connecting rod and a second connecting rod. The first connecting rod is rotatably connected to the first pressure plate, and the second connecting rod has two sections, respectively located at both ends of the lifting seat. The second connecting rod is rotatably connected to the second pressure plate. The two pressure plates share a single first transmission component, resulting in a more compact structure and lower equipment cost.

[0021] Preferably, the movable frame is connected to the drive component;

[0022] The driving component includes a screw, a nut, and a motor. The screw is mounted on the frame and connected to the motor.

[0023] The frame is equipped with a linear guide rail, and a slider is slidably mounted on the linear guide rail. The slider and nut are mounted on the base frame.

[0024] Preferably, the forming station is equipped with an air chamber, and the bottom frame is equipped with a second transmission component that drives it to rise and fall relative to the air chamber;

[0025] During vacuum forming, the second transmission component drives the bottom frame to move downward, and the bottom frame is sealed and pressed together with the air chamber.

[0026] Preferably, the second transmission component includes a pressing component, a power component for driving the pressing component to rise and fall, and a reset component for driving the bottom frame to reset. The power component is mounted on the frame, and the pressing component is located above the outer edge of the bottom frame and can act on the outer edge of the bottom frame.

[0027] The reset assembly includes a column, a spring, and a guide sleeve that matches the column. The column is mounted on the slider, the guide sleeve is mounted on the bottom frame and sleeved over the column, and the spring is sleeved over the column and positioned between the guide sleeve and the slider. During the vacuum forming operation, the power component drives the lower pressure component to move downward, which in turn pushes the bottom frame downward and seals it against the air chamber. After the vacuum forming is completed, the power component drives the lower pressure component to move upward, and the spring pushes the bottom frame upward to reset. Attached Figure Description

[0038] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. This bag processing equipment includes a forming mechanism 3, a heating mechanism 7, an edge trimming mechanism 6, and a robotic arm 5. The bag processing equipment has a forming station 1, a heating station 2, and an edge trimming station 8. The forming station 1 and the heating station 2 are arranged adjacent to each other. The edge trimming station 8 is located to the side of the forming station 1. The robotic arm 5 is located between the edge trimming station 8 and the forming station 1, i.e., the robotic arm 5 is close to both the edge trimming station 8 and the forming station 1. The forming mechanism includes a moving frame that moves laterally between the forming station and the heating station. The edge trimming mechanism 6 is located at the edge trimming station and includes a laser cutting head 61. The robotic arm 5 is equipped with a suction device. The robotic arm 5 drives the suction device to deliver the formed product from the forming station 1 to the edge trimming station 8, and the suction device rotates relative to the laser cutting head 61. Because the trimming and vacuum forming processes are separated, the trimming of the bags is given an independent space and is not affected by other processing parts, making the trimming and punching operations of the bags more operable. This utility model uses a robotic arm 5 to directly enter the forming station 1 and take out the formed bags from the forming station 1 and send them to the trimming station 8, saving the handling and conveying processes, saving space, eliminating manual operation, improving work efficiency, and reducing costs. Furthermore, the robotic arm 5 moves and rotates the vacuum-formed bags relative to the laser cutting head 61. The laser cutting head 61 remains stationary during operation. As the bags move and rotate, the laser cutting head 61 cuts off the excess waste material of the bags, realizing trimming and punching.

[0039] In the figure, there are two forming stations 1 and two trimming stations 8. There are two sets of robotic arms 5. The two sets of forming stations 1 are set on both sides of the heating station 2, and the two sets of trimming stations 8 are respectively set on the sides of the two sets of forming stations 1. Each set of robotic arms 5 corresponds to one set of forming station 1 and one set of trimming station 8. The trimming station 8, forming station 1, and heating station 2 form a processing space. The robotic arms 5 are set in the processing space. Compared with single-station forming, dual-station forming shares one heating station 2, which makes reasonable use of the characteristics of fast heating speed and slow forming speed, greatly improving the overall production speed. At the same time, the overall area occupied is small, and the manual intervention is reduced, thus reducing the production cost.

[0040] The robotic arm 5 is a six-axis robotic arm; it includes two vertical axes of rotation, three horizontal axes of rotation, and one vertical axis of rotation. The six-axis robotic arm 5 meets the requirements for irregularly shaped movement, enabling the trimming and punching of bags of different shapes. To improve the stability of the material suction component, the suction component is a suction cup, and several suction cups are provided. These suction cups are mounted on a moving frame 51, which is connected to the robotic arm 5. The moving frame 51 facilitates the installation of the suction cups and increases their coverage area, achieving stable adsorption of shaped bags. See attached document. Figure 4The robotic arm 5 includes a base 52, a first arm 54, a second arm 56, a first connecting seat 53, a second connecting seat 55, and a connector 57. The first connecting seat 53 is rotatably connected to the base 52 via a first vertical axis 511. The first arm 54 is rotatably connected to the first connecting seat 53 via a first horizontal axis 512. The second connecting seat 55 is rotatably connected to the first arm 54 via a second horizontal axis 513. The second arm 56 is rotatably connected to the second connecting seat 55 via a first vertical axis 514. The connector 57 is rotatably connected to the second arm 56 via a third horizontal axis 515. The moving frame 51 is rotatably connected to the connector 57 via a second vertical axis 516. The robotic arm 5 can realize the omnidirectional movement and rotation of the moving frame 51, and can move and rotate the adsorbed bag relative to the laser cutting head 61. The laser cutting head 61 remains stationary during operation. As the bag moves and rotates, the laser cutting head 61 cuts off the excess waste material of the bag, realizing trimming and punching.

[0041] The movable frame includes a base frame 32 and pressure plates 31. The center of the base frame is empty and is typically square. Four pressure plates 31 are provided, corresponding to the four sides of the base frame 32. The four pressure plates 31 are oscillating on the base frame 32. When the four pressure plates 31 are pressed against the four sides of the base frame 32, they form a closed square. The square opening formed by the pressure plates 31 corresponds to the square opening in the base frame 32, allowing space for the sheet 4 to bulge upwards after heating during molding and for the molding die to be positioned. During loading, the four pressure plates 31 oscillate outwards to allow space for loading. The sheet 4 is placed on the base frame 32, and the four sides of the base frame 32 support the sheet 4. The four pressure plates 31 oscillate in the opposite direction and press against the four sides of the base frame 32, sealing and fixing the sheet 4 around its perimeter. To improve sealing, sealing strips are provided on the four sides where the bottom frame and the pressure plate are pressed together, improving the sealing performance when the pressure plate and the bottom frame are pressed together and preventing air leakage during vacuum forming. The four pressure plates 31 occupy little space when swinging, leaving sufficient operating space at the forming station 1, allowing the robot arm to directly enter the forming station 1 to pick up materials.

[0042] The two ends of the pressure plate 31 are rotatably mounted on the base frame 32 via pivots. The outward-facing side of the pressure plate 31 is connected to the first transmission component 33 that drives its swing. The first transmission component is mounted on the base frame. To allow the pressure plate 31 to swing at a larger angle and to provide sufficient space for feeding the sheet 4 and unloading the finished product, the outward-facing side of the pressure plate 31 in its horizontal state is connected to an upwardly inclined drive arm 35. The drive arm 35 is connected to the first transmission component 33 that drives the pressure plate 31 to swing. When the pressure plate 31 is pressed against the bottom frame 32, it is nearly horizontal. At this time, the drive arm 35 is tilted upward relative to the horizontal plane. The first transmission component pulls down the drive arm to make the pressure plate swing outward. The upward tilting drive arm 35 swings at a larger angle than the horizontal drive arm 35, so that the pressure plate 31 rotates at a larger angle, thus making enough room for the sheet material 4 to be fed and for the robot arm to pick up the finished product. The first transmission component pushes the drive arm upward to make the pressure plate swing inward and press against the bottom frame. The first transmission component does not occupy the position above the bottom frame, so that the upper operating space of the forming station is larger.

[0043] The first transmission component 33 includes a linear electric cylinder 331, a lifting seat 332, a connecting rod, and a guide post 333. The linear electric cylinder 331 and the guide post 333 are mounted on the base frame 32. The lifting seat 332 is connected to the lead screw of the linear electric cylinder 331. The two ends of the connecting rod are rotatably connected to the pressure plate 31 and the lifting seat 332, respectively. The linear electric cylinder 331 drives the lifting seat 332 to rise and fall along the guide post 333. During vacuum forming, the linear electric cylinder 331 has a self-locking function to prevent retraction, provides excellent clamping effect, and eliminates the need for additional components to apply pressure, ensuring that the upper part of the forming station 1 is unobstructed and unobstructed.

[0044] To reduce costs, the first transmission component 33 is provided in two sets, with one set of the first transmission component 33 driving two adjacent pressure plates 31 to swing. See attached document. Figure 7 and 8 The two adjacent pressure plates 31 of the first transmission component 33 are respectively the first pressure plate 31131 and the second pressure plate 31231. The connecting rod is divided into a first connecting rod 334 and a second connecting rod 335. The first connecting rod 334 is rotatably connected to the first pressure plate 31131. The second connecting rod 335 has two rods, which are respectively set at both ends of the lifting seat 332. The second connecting rod 335 is rotatably connected to the second pressure plate 31231. The two pressure plates 31 share a first transmission component 33. When the linear electric cylinder 331 drives the lifting seat 332 to move upward along the guide post 333, the first connecting rod 334 and the second connecting rod 335 respectively drive the first pressure plate 31131 and the second pressure plate 31231 to rotate towards the inner circumference of the bottom frame 32 until the pressure plates 31 and the surface of the bottom frame 32 are pressed together. When the linear electric cylinder 331 drives the lifting seat 332 to move downward, the first pressure plate 31131 and the second pressure plate 31231 rotate towards the outer circumference of the bottom frame 32.

[0045] The moving frame is connected to the driving component 34; the driving component 34 can be a cylinder. To ensure the accuracy and stability of the movement, the driving component 34 includes a screw 343, a nut 342 and a motor 341. The screw 343 is mounted on the frame and connected to the motor 341. The frame is provided with a linear guide rail 344. A slider 345 is slidably mounted on the linear guide rail 344. The slider 345 and the nut 342 are mounted on the base frame 32.

[0046] The forming station is equipped with an air chamber 37, and the bottom frame 32 is equipped with a second transmission component 36 that drives it to rise and fall relative to the air chamber. During vacuum forming, the second transmission component drives the bottom frame 32 to move downward, and the bottom frame and the air chamber 37 are sealed and pressed together. The second transmission component 36 includes a pressing member 362, a power member 361 that drives the pressing member to rise and fall, and a reset component 363 that drives the bottom frame to reset. The power member is mounted on the frame and below the bottom frame. The pressing member 362 is located above the outer edge 321 of the bottom frame and can act on the outer edge of the bottom frame. The reset component 363 includes a column 3631, a spring 3632, and a guide sleeve 3633 that matches the column 3631. The column 3631 is mounted on a slider 345. The guide sleeve 3633 is mounted on the bottom frame 32 and sleeved outside the column 3631. The spring 3632 is sleeved outside the column 3631 and located between the guide sleeve 3633 and the slider 345. During the vacuum forming process, the pressure plate 31 swings and presses against the base frame 32. The power component drives the lower pressure component 362 to move downwards, pushing the outer edge of the base frame to move downwards and seal it against the air chamber 37. At this time, the spring is compressed. After the vacuum forming is completed, the power component drives the lower pressure component 362 to move upwards, and the spring force pushes the base frame upwards to return to its original position. The second transmission component is movable with the base frame, which does not affect the movement of the base frame, while ensuring that the base frame and the air chamber are sealed and pressed together at the forming station.
