Description

Technical Field

[0001] This utility model relates to the field of case packing machine technology, specifically a multi-functional case packing machine gripping mechanism that can position and place a pad. Background Technology

[0002] A case packer is a device that semi-automatically or automatically loads unpackaged or small-packaged products into transport packaging. Its working principle involves arranging and quantitatively loading products into boxes (corrugated cardboard boxes, plastic boxes, pallets) and then closing or sealing the openings. According to requirements, a case packer should have functions for box forming (or opening), weighing, and packing; some also include sealing or strapping functions.

[0003] For example, Chinese patent CN221316865U discloses a gripping mechanism for a case packing machine, including a support frame. The bottom surface of the support frame is equipped with a gripping mechanism and a clamping mechanism. A first hydraulic rod drives a first slider to move, which in turn moves the first support frame, thus adjusting the position of the first support frame according to the different materials. A third hydraulic rod drives a second slider and a fixed plate to move, thereby adjusting the height of the second support frame according to the height of different materials. A first motor drives a double-ended threaded rod to rotate, which in turn moves two third sliders, which in turn move a first baffle and a fixed column. A second hydraulic rod drives a fourth slider to deflect, thereby adjusting the angle of the inclined plate according to the size of different materials. A clamping plate is used to clamp the materials, facilitating better material gripping operations for the case packing machine.

[0004] However, the gripping mechanism of the aforementioned case packing machine can only perform biaxial gripping and cannot extend vertically. In actual case packing scenarios, materials may be placed on shelves, pallets, or workbenches at different heights, making it difficult to grip materials at higher or lower positions. Furthermore, during the material gripping process, there is no automatic identification of the gripped materials and their placement positions. This requires frequent manual adjustment of equipment parameters or manual movement of the gripping mechanism when gripping different materials or placing them in different positions, resulting in a discontinuous operation process, increased idle time of the equipment, and reduced actual working efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional packing machine gripping mechanism with a positioning and placement pad, so as to solve the problem mentioned in the background art that it does not have automatic identification of the material being gripped and the placement position, and requires frequent manual adjustment of equipment parameters or manual movement of the gripping mechanism when gripping different materials or placing them in different positions, resulting in a discontinuous operation process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-functional box packer gripping mechanism with a positioning and placement pad includes: a guide rail and two sets of hangers. Two sets of first linear modules are fixedly installed at one end of the inner side of each of the two sets of hangers. A second linear module is fixedly installed between the moving blocks of the four sets of first linear modules. A gripping mechanism is fixedly installed on the lower surface of the moving block of the second linear module. An n-shaped groove is opened on the lower surface of each of the two sets of hangers. A support wheel is rotatably installed in the n-shaped groove and the support wheel rolls in the guide rail.

[0008] Preferably, an arc cover is fixedly installed between the two sets of hangers, and a drive wheel is rotatably installed inside the arc cover, the drive wheel rolling within the guide rail.

[0009] Preferably, the drive wheel is fixedly connected to the output shaft of the motor, and the motor is fixedly installed at one end of the arc cover, so that the drive wheel can drive the two sets of hangers to move linearly within the guide rail by being driven by the motor.

[0010] Preferably, the gripping mechanism can perform triaxial gripping through the transmission of the drive wheel, the first linear module, and the second linear module.

[0011] Preferably, a camera is fixedly installed on the lower surface of the hanger to monitor the internal area between the two sets of guide rails.

[0012] Preferably, the camera is electrically connected to a computer.

[0013] Preferably, the clamping mechanism includes a mounting plate, which is fixedly mounted on the lower surface of the moving block of the second linear module. Connecting plates are fixedly mounted on the four corners of the lower surface of the mounting plate, and each of the four sets of connecting plates is rotatably mounted with a gripper, and the grippers of each pair of sets are opposite to each other.

[0014] Preferably, an electric push rod is fixedly mounted on the lower surface of the mounting plate, a push plate is fixedly mounted on the lower surface of the piston rod of the electric push rod, and connecting arms are rotatably mounted on both ends of the push plate, with the other end of the connecting arm rotatably mounted on the outer surface of the gripper.

[0015] Preferably, this allows the connecting arm to be lifted or pushed by an electric push rod via a push plate, and the lifted connecting arm can pull the gripper to rotate inward and retract, while the pushed connecting arm can push the gripper to rotate outward and expand.

[0016] Preferably, the lower surfaces of all four sets of grippers are equipped with half-toothed parts by means of bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Through the design of the first linear module, the second linear module, the camera, the drive wheel, and the gripping mechanism, during use, the material to be gripped can be conveyed to the area between the hangers, placing it within the monitoring range of the camera. The camera then transmits the captured image data to a computer via a wired connection. Image processing software extracts key information such as the material's features, contours, position coordinates, and orientation angles. Based on the material's coordinate information, the computer sequentially controls the second linear module and the motor. The second linear module drives the gripping mechanism on the lower surface of the moving block to move laterally, while the motor drives the drive wheel to roll within the guide rail, thus enabling… The drive wheel can move the gripping mechanism inside the hanger longitudinally, positioning it directly above the material. Then, the first linear module can be activated to move the gripping mechanism on the lower surface of the second linear module vertically downward. This allows the gripping mechanism to lift and pick up the material, which is then moved to the designated placement position by the second linear module and the drive wheel. This automates the entire material grabbing and placement process, eliminating the need for manual intervention in positioning and operation. This significantly saves time and improves work efficiency. In large-scale production scenarios, it can quickly and continuously complete material grabbing and packing tasks, significantly increasing the overall capacity of the production line.

[0019] 2. Through the design of the electric push rod, push plate, connecting plate, grippers, and connecting arm, when gripping materials, the electric push rod can be activated to pull the push plate on the lower surface of the piston rod, which pulls the connecting arm upward. This allows the connecting arm to synchronously pull the grippers at both ends to rotate and retract inward, thereby clamping the material within the grippers. For different types of materials, the operator can adjust the orientation of the half-tooth of the gripper to better fit the contour of the material and find a suitable point of force, thus firmly gripping the material. For smooth materials, adjusting the orientation of the half-tooth of the gripper can change the contact angle and friction distribution between the gripper and the material, preventing the material from slipping during the gripping process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This embodiment provides the following technical solution:

[0027] like Figures 1-3 As shown, a multi-functional box-packing machine gripping mechanism capable of positioning and dispensing pads includes: a guide rail 101 and two sets of hangers 1. Two sets of first linear modules 105 are fixedly installed at one end of the inner side of each set of hangers 1. A second linear module 106 is fixedly installed between the moving blocks of the four sets of first linear modules 105. A gripping mechanism 2 is fixedly installed on the lower surface of the moving block of the second linear module 106. An n-shaped groove 102 is formed on the lower surface of each set of hangers 1. A support wheel 108 is rotatably installed within the n-shaped groove 102 and rolls within the guide rail 101. An arc-shaped cover 103 is fixedly installed between the two sets of hangers 1. A drive wheel 109 is rotatably installed within the arc-shaped cover 103 and rolls within the guide rail 101. The drive wheel 109 is fixedly connected to the output shaft of the motor 104. The motor 104 is fixedly installed at one end of the arc cover 103, so that the drive wheel 109 can drive the two sets of hangers 1 to move linearly within the guide rail 101 through the drive wheel 109, the first linear module 105 and the second linear module 106. The gripping mechanism 2 can perform triaxial gripping through the transmission of the drive wheel 109, the first linear module 105 and the second linear module 106. A camera 107 is fixedly installed on the lower surface of the hanger 1 and monitors the internal range between the two sets of guide rails 101. The camera 107 will transmit the collected image data to the computer through a wired connection, and extract key information such as the characteristics, contour, position coordinates and attitude angle of the gripped material through image processing software.

[0028] Through the design of the first linear module 105, the second linear module 106, the camera 107, the drive wheel 109, and the gripping mechanism 2, in use, the material to be gripped can be conveyed to the range between the hangers 1, placing it within the monitoring range of the camera 107. The camera 107 can then transmit the acquired image data to a computer via a wired connection. Image processing software can then extract key information such as the material's features, contours, position coordinates, and attitude angles. Based on the material's coordinate information, the computer can sequentially control the second linear module 106 and the motor 104. The second linear module 106 drives the gripping mechanism 2 on the lower surface of the moving block to move laterally, while the motor 104 drives the drive wheel 109 on the guide rail 1. The internal rolling mechanism 101 enables the drive wheel 109 to drive the gripping mechanism 2 within the hanger 1 to move longitudinally, positioning the gripping mechanism 2 directly above the material. Subsequently, the first linear module 105 is activated, causing the gripping mechanism 2 on the lower surface of the second linear module 106 to move vertically downward. This allows the gripping mechanism 2 to lift and grip the material, and then, through the second linear module 106 and the drive wheel 109, move the material to the designated placement position. This automates the entire material gripping and placement process, eliminating the need for manual intervention in positioning and operation, significantly saving time and improving work efficiency. In large-scale production scenarios, it can quickly and continuously complete the material gripping and packing tasks, significantly increasing the overall production capacity of the production line.

[0029] like Figure 4 As shown, the clamping mechanism 2 includes a mounting plate 201, which is fixedly mounted on the lower surface of the moving block of the second linear module 106. Connecting plates 204 are fixedly mounted at the four corners of the lower surface of the mounting plate 201. Each of the four sets of connecting plates 204 is rotatably mounted with a gripper 205, and each pair of grippers 205 is in a relative position. An electric push rod 202 is fixedly mounted on the lower surface of the mounting plate 201. A push plate 203 is fixedly mounted on the lower surface of the piston rod of the electric push rod 202. Connecting arms 206 are rotatably mounted on both sides of the push plate 203. The other end of the connecting arm 206 is rotatably mounted on the outer surface of the gripper 205, so that the connecting arm 206 can be lifted or pushed by the electric push rod 202 through the push plate 203. The lifted connecting arm 206 can pull the gripper 205 to rotate inward and retract, and the pushed connecting arm 206 can push the gripper 205 to rotate outward and expand. Half teeth 207 are detachably mounted on the lower surface of each of the four sets of grippers 205 by bolts.

[0030] Through the design of the electric push rod 202, push plate 203, connecting plate 204, gripper 205, and connecting arm 206, when gripping materials, the electric push rod 202 can be activated to pull the push plate 203 on the lower surface of the piston rod, which in turn pulls the connecting arm 206 upward. This allows the connecting arm 206 to synchronously pull the grippers 205 at both ends to rotate and retract inward, thereby clamping the material within the grippers 205. For different types of materials, the orientation of the half-tooth 207 of the gripper 205 can be adjusted by the operator to allow the gripper 205 to better conform to the contour of the material and find a suitable point of force, thus firmly gripping the material. For materials with smooth surfaces, adjusting the orientation of the half-tooth 207 of the gripper 205 can change the contact angle and friction distribution between the gripper 205 and the material, preventing the material from slipping during the gripping process.

[0031] Based on the above technical solution, the working steps of this solution are summarized as follows: In use, the material to be gripped can be conveyed to the area between the hangers 1, placing it within the monitoring range of the camera 107. The camera 107 then transmits the collected image data to a computer via a wired connection. Image processing software extracts key information such as the material's features, contours, position coordinates, and orientation angles. The computer then controls the second linear module 106 and the motor 104 sequentially based on the material's coordinate information. The second linear module 106 drives the gripper 205 on the lower surface of the moving block to move laterally, while the motor 104 drives the drive wheel 109 to roll within the guide rail 101. This causes the drive wheel 109 to drive the gripper 205 within the hanger 1 to move longitudinally, allowing the gripper to... 205 is moved directly above the material. Then, the first linear module 105 is activated to move the gripper 205 on the lower surface of the second linear module 106 vertically downward and fit around the material. Then, the electric push rod 202 is activated to pull the push plate 203 on the lower surface of the piston rod to pull the connecting arm 206 upward. This allows the connecting arm 206 to synchronously pull the grippers 205 at both ends to rotate and retract inward, thereby clamping the material in the grippers 205. Then, the material can be moved to the set placement position again by the second linear module 106 and the drive wheel 109. The electric push rod 202 is activated to push the push plate 203 to push the connecting arm 206 out, thereby allowing the connecting arm 206 to synchronously push the grippers 205 at both ends out, so that the clamped material is positioned and placed in the set placement position.

[0032] In summary, this system automates the entire material grabbing and delivery process, eliminating the need for manual intervention in positioning and operation. This significantly saves time, improves work efficiency, and enables rapid and continuous material grabbing and packing in large-scale production scenarios, thereby significantly increasing the overall production line capacity.
