Description

Technical Field

[0001] The utility model relates to a conveying device for automobile parts, in particular to a conveying device for long strip products such as I-beams. Background Art

[0002] In the processing of auto parts, long products such as I-beam structures are often transported. Under normal circumstances, the transportation of I-beams is sometimes done manually. When more I-beams are required, a special conveying device is often designed for the conveying process to achieve automatic conveying. For example, the Chinese invention patent application with patent application number CN202011041700.7 (application publication number CN112171118A) "An automatic welding conveying device for I-beams" is used to convey I-beams placed side by side. Figure 1 The long strip workpiece 1' shown, in order to ensure that each workpiece is transported in an orderly manner during the conveying process, adopts a telescopic component and an abutment component at the end of the conveying body. Although the automated conveying equipment improves the efficiency of conveying, the telescopic component and the abutment component require independent assembly stations, which increases the complexity of the conveying device. In summary, the existing technology needs to be further improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a conveying device capable of reducing the complexity of assembly in view of the above-mentioned existing technical status, especially a conveying device for long strip products.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: the conveying device includes:

[0005] The frame is provided with a material unloading station, which is used to unload the product pieces to be transported; and

[0006] A conveying mechanism, arranged on the frame, for conveying product pieces;

[0007] It is characterized by also including:

[0008] The conveying mechanism is arranged at intervals along the conveying direction and perpendicular to the conveying direction and has at least two independent carrier elements for placing single product pieces. The center of the carrier element has a partially downwardly recessed groove, and the preset direction of the carrier element is the vertical direction perpendicular to the conveying direction.

[0009] In order to improve the fit between the product and the groove of the carrier element, the carrier element is further connected to the conveying mechanism through a first adjustment mechanism, the first adjustment mechanism includes a first adjustment platform engaged with the carrier element and a second adjustment platform located below the first adjustment platform, and a first adjustment hole with a length direction parallel to the conveying direction is provided on the first adjustment platform and / or the second adjustment platform. When the product with an incorrect posture is transferred from the unloading station to the conveying mechanism, the two ends of the product will collide with the carrier element, and the carrier element can move relative to the conveying mechanism in the same direction as the deviation direction of the two ends of the product through the first adjustment mechanism, so that the two ends of the product fall into the groove of the carrier element, preventing the long strip product from tipping over.

[0010] In order to achieve flexible adjustment of the first adjustment mechanism, preferably, the first adjustment hole is opened on the first adjustment platform, and correspondingly, the second adjustment platform is provided with a first mounting hole, and a limit screw is installed on the first mounting hole, the limit screw is threadedly connected in the first mounting hole and the head is exposed outside the first adjustment hole for adjustment, so that the first adjustment platform can be adjusted relative to the second adjustment platform in parallel to the transmission direction. In this technical solution, the setting of the exposed head of the limit screw facilitates the operator to adjust the tightness between the first adjustment mechanism and the transmission mechanism without completely releasing the connection between the two, thereby enabling the first adjustment mechanism to move flexibly while maintaining the connection between the first adjustment mechanism and the transmission mechanism.

[0011] In order to further increase the adjustment range of the carrier element, preferably, the carrier element can also be adjusted relative to the first adjustment platform in parallel to the conveying direction. This technical solution enables the carrier element to increase its movement range in parallel to the conveying direction based on the movement range of the first adjustment platform. At the same time, the relative movement between the first adjustment mechanism and the carrier element, and the first adjustment platform and the conveying mechanism reduces the shear force transmitted to the conveying mechanism caused by the deviation of the two ends of the product, protects the conveying mechanism, and has the advantage of "one object for two purposes".

[0012] In order to ensure stable transportation of products on the conveying mechanism, preferably, the cross section of the first adjustment platform is in the shape of a Chinese character "J", including a joining platform directly joined to the carrier element, a first adjustment foot arranged in parallel with the joining platform, a second adjustment foot, and a connecting wall respectively connecting the joining platform and the corresponding adjustment foot, and the first adjustment hole is respectively arranged on the first adjustment foot and the second adjustment foot. The Chinese character "J" structure of the first adjustment platform in this technical solution increases its own structural strength, so that the first adjustment platform and the carrier element can stably receive both ends of the product, avoiding deformation of the first adjustment platform due to excessive weight of the product.

[0013] In order to enable the carrier element and the first adjustment platform to move relative to each other, preferably, the carrier element is located at the joint and / or the joint platform is provided with a second adjustment hole whose length direction is parallel to the conveying direction. The second adjustment hole in this technical solution provides the carrier element with a movable space relative to the first adjustment platform.

[0014] In order to flexibly adjust the carrier element relative to the first adjustment platform, preferably, the bottom of the groove of the carrier element is provided with the second adjustment hole, and correspondingly, the joint platform is provided with a second mounting hole that is connected to the second adjustment hole at the joint, and the limit screw is installed on the second mounting hole, and the limit screw is threadedly connected in the second mounting hole and the head is located in the second adjustment hole, so that the carrier element can be adjusted relative to the first adjustment platform in parallel to the conveying direction. This technical solution can adjust the tightness of the limit screw so that the carrier element and the first adjustment platform can be flexibly moved in parallel to the conveying direction while maintaining the connection.

[0015] In order to ensure that the first adjustment platform and the carrier element do not separate during the transmission of the conveying mechanism, preferably, the second adjustment hole is set vertically through the junction of the bottom of the carrier element groove and the bonding platform, and the lower peripheral edge of the hole wall of the second adjustment hole extends inward to form a resting platform for the head of the limit screw to rest. In this technical solution, the head of the limit screw is fixed in the second adjustment hole through the resting platform, which enhances the firmness of the connection between the bonding platform and the carrier element.

[0016] In order to keep the long strips of products balanced when transported on the conveying mechanism, since the products are prone to tipping over due to their own weight when being unloaded onto the carrier element, preferably, the conveying mechanism is a first conveying chain and a second conveying chain located on both sides of the frame and driven by their own driving sources. Correspondingly, the carrier elements are also arranged on the first conveying chain and the second conveying chain, and the two are symmetrically distributed. In this technical solution, the carrier elements on the first conveying chain and the second conveying chain fix the two ends of the product, so that the center of gravity of the product falls in the center of the conveying mechanism, avoiding the phenomenon of the product sliding to one side when the product is transferred to the conveying mechanism.

[0017] Compared with the prior art, the advantages of the present invention are: the telescopic assembly and the abutment assembly in the prior art are replaced by a carrier element, so that it can be directly connected to the conveying mechanism perpendicular to the conveying direction, saving installation space while directly placing product parts with the help of its own groove structure. The overall structure is simpler to reduce the complexity of assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 11As shown, it is a preferred embodiment of the utility model. The conveying device of this embodiment is mainly used for products on the transportation assembly line. When the transported product is a long strip product such as an I-beam, the support unit on the conveying device must provide the user with the function of adaptive adjustment or correction of the incorrect posture of the product during transportation to prevent the product from tipping over. The frequent contact between the support unit and the product increases the maintenance frequency of the support unit. Therefore, the simplicity of the support unit structural design is conducive to daily maintenance and cost reduction. For example, when the manipulator clamps the center of the long strip product and transports it to the top of the conveying device, due to the horizontal movement of the manipulator, the product will be offset at a random angle with the manipulator clamping as the rotation center. At this time, the user hopes that the carrier element can be adaptively adjusted with the offset of the two ends of the product to prevent the product from tipping over. The adjustment action is generated by the collision between the product and the support unit. After the transportation is completed, the maintenance personnel stop the machine to repair the support unit. The simple structure improves the maintenance efficiency of the support unit when the maintenance personnel stop the machine for inspection. Therefore, it will be beneficial to provide a conveying device with a simple structure. The structural description of this conveying device will be expanded as follows:

[0031] See also Figures 1 to 7 The conveying device includes a frame 1 with a material unloading station 2, which is used to unload the product to be transported; and a conveying mechanism 3 arranged on the frame 1 for conveying the product, the conveying mechanism 3 is arranged at intervals along the conveying direction and perpendicular to the conveying direction and has at least two independent carrier elements 4 for placing a single product, the center of the carrier element 4 has a groove 40 partially concave downward, and the preset direction of the carrier element 4 is a vertical direction perpendicular to the conveying direction. The unloading station 2 is set in the middle of the frame 1, the carrier element 4 is made of nylon, the groove 40 is a "U"-shaped structure with an opening upward, and the size of the groove 40 is larger than the size of the product, so that the product can fall into the groove 40 smoothly.

[0032] In this embodiment, the carrier element 4 is connected to the conveying mechanism 3 through the first adjustment mechanism 5. The first adjustment mechanism 5 includes a first adjustment platform 51 engaged with the carrier element 4 and a second adjustment platform 52 located below the first adjustment platform 51. The first adjustment platform 51 and the second adjustment platform 52 are provided with first adjustment holes 53 whose length direction is parallel to the conveying direction. When the product with an incorrect posture is transferred from the unloading station 2 to the conveying mechanism 3, the two ends of the product will collide with the carrier element 4. The carrier element 4 can move in the same direction as the deviation direction of the two ends of the product relative to the conveying mechanism 3 through the first adjustment mechanism 5, so that the two ends of the product fall into the groove 40 of the carrier element 4, which prevents the long strip product from falling over and improves the fit between the product and the groove 40 of the carrier element.

[0033] In this embodiment, the first adjustment hole 53 is formed in the first adjustment platform 51. Correspondingly, a first mounting hole 54 is formed in the second adjustment platform 52, and a limit screw is mounted on the first mounting hole 54. The limit screw is threadedly connected in the first mounting hole 54 and its head is exposed outside the first adjustment hole 53 for adjustment, so as to realize the adjustment of the first adjustment platform 51 relative to the second adjustment platform 52 in the direction parallel to the conveying direction. By the arrangement of the exposed head of the limit screw, it is convenient for the operator to adjust the tightness between the first adjustment mechanism 5 and the conveying mechanism 3 without completely releasing their connection relationship, so that they can move flexibly while maintaining the connection relationship between the first adjustment mechanism 5 and the conveying mechanism 3. The limit screw is a common component and is not drawn in the figure, for the flexible adjustment of the first adjustment mechanism 5.

[0034] In addition, the adjustment range of the carrier element 4 is further increased to adapt to more skewed posture blanking workpieces. Therefore, in this embodiment, the carrier element 4 can also be adjusted relative to the first adjustment platform 51 in the direction parallel to the conveying direction. Specifically, the carrier element 4 can increase the moving range in the direction parallel to the conveying direction on the basis of the moving range of the first adjustment platform 51. At the same time, the relative movement between the first adjustment mechanism 5 and the carrier element 4, and between the first adjustment platform 51 and the conveying mechanism 3 also reduces the shear force transmitted to the conveying mechanism 3 caused by the offset at both ends of the product, protecting the conveying mechanism 3, and having the advantage of "one thing with two uses". See Figure 5 , the cross-section of the first adjustment platform 51 is in a "ji" shape, including a joint platform 511 directly connected to the carrier element 4, a first adjustment support leg 512, a second adjustment support leg 513 parallel to the joint platform 511, and connection walls 514 connecting the joint platform 511 and the corresponding adjustment support legs respectively. The first adjustment holes 53 are respectively arranged on the first adjustment support leg 512 and the second adjustment support leg 513. The "ji" shape structure of the first adjustment platform 51 increases its own structural strength, so that the first adjustment platform 51 and the carrier element 4 can stably support both ends of the product, avoiding the deformation of the first adjustment platform 51 due to the overweight of the product, and can also ensure the stable transportation of the product on the conveying mechanism 3 and improve the operation rate of the automatic production line.

[0035] In this embodiment, the carrier element 4 is provided with a second adjustment hole 6 at the joint and on the joint platform 511, and the length direction of the second adjustment hole 6 is parallel to the conveying direction. The setting of the second adjustment hole 6 in this technical solution provides an activity space for the carrier element 4 relative to the first adjustment platform 51, so that the carrier element 4 and the first adjustment platform 51 can move relative to each other.

[0036] In this embodiment, the bottom of the groove 40 of the carrier element 4 is provided with a second adjustment hole 6. Correspondingly, the joint platform 511 is provided with a second mounting hole 515 which is connected with the second adjustment hole 6 at the joint, and a limit screw is installed on the second mounting hole 515. The limit screw is threadedly connected in the second mounting hole 515 and the head is located in the second adjustment hole 6, so that the carrier element 4 can be adjusted in parallel to the conveying direction relative to the first adjustment platform 51. The tightness of the limit screw can be adjusted so that the carrier element 4 and the first adjustment platform 51 can be flexibly moved in parallel to the conveying direction while maintaining the connection, which facilitates the flexible adjustment of the carrier element 4 relative to the first adjustment platform 51.

[0037] The first adjustment platform 51 and the carrier element 4 need to be assembled firmly on the conveying mechanism 3 to ensure stable transportation of the product. Therefore, in this embodiment, the second adjustment hole 6 is set up and down through the joint of the bottom of the groove of the carrier element 4 and the joint platform 511, and the lower peripheral edge of the hole wall of the second adjustment hole 6 extends inward to form a resting platform 61 for the head of the limit screw to rest. In this technical solution, the head of the limit screw is fixed in the second adjustment hole 6 through the resting platform 61, which enhances the firmness of the connection between the joint platform 511 and the carrier element 4.

[0038] Finally, in order to keep the long strip products balanced when transported on the conveying mechanism, since the products are prone to tipping over when being unloaded onto the carrier element due to their own weight, the conveying mechanism 3 in this embodiment is a first conveying chain 31 and a second conveying chain 32 located on both sides of the frame 1 and driven and conveyed by their respective driving sources. Correspondingly, the carrier element 4 is also arranged on the first conveying chain 31 and the second conveying chain 32, and the two are symmetrically distributed. The carrier elements 4 on the first conveying chain 31 and the second conveying chain 32 fix the two ends of the product, so that the center of gravity of the product falls in the center of the conveying mechanism 3, avoiding the phenomenon that the product pieces slide to one side when the product is transferred to the conveying mechanism 3.

[0039] In summary, the carrier element 4 can be adjusted as follows according to the deviation of the two ends of the product with incorrect posture:

[0040] a. The product falls on the edge of the groove wall of the groove 40 of the carrier element 4, and the second adjustment platform 52 and the first adjustment platform 51 are adjusted adaptively: please refer to Figures 8 to 9, before unloading, the carrier element 4, the second adjustment platform 52, and the first adjustment platform 51 on the first conveying chain 31 and the second conveying chain 32 are aligned perpendicular to the conveying direction. Since the product is long and the posture of the robot arm is unstable when grasping the material, the product is not necessarily aligned on the horizontal plane at both ends perpendicular to the conveying direction when unloading, so that the two ends of the product and the notch of the groove 40 of the carrier element 4 are offset parallel to the conveying direction. When the product at the unloading station 2 first contacts the inner side of the groove wall of the groove 40 of the carrier element 4, the carrier element 4 is subjected to the force of the product in the same direction of the offset, and the first adjustment platform 51 connected to it moves in the offset direction of the product through the second adjustment hole 6 relative to the second adjustment platform 52, so that the notch of the groove 40 of the carrier element 4 is aligned with the two ends of the product, and the product falls into the carrier element 4 after being subjected to the reaction force of the carrier element 4;

[0041] b. Please refer to Figures 10 to 11 The sliding friction force generated by the above movement drives the first adjustment platform 51 to move in the same direction as the second adjustment platform 52 through the first adjustment hole 53, and the carrier element 4 is adjusted as a whole. At this time, the carrier elements 4 on the first conveying chain 31 and the second conveying chain 32 are staggered with each other in a direction perpendicular to the conveying direction; the displacement generates friction between the first adjustment platform 51 and the second adjustment platform 52, and is transmitted to the connection between the second adjustment platform 52 and the conveying chain on the conveying mechanism 3;

[0042] The conveying device reduces the structural complexity of the conveying device by arranging multiple carrier elements 4 for fixing single products on the conveying mechanism, and only uses threaded screw holes for connection, which is convenient for maintenance personnel to stop the machine for maintenance, thereby improving the efficiency of maintenance; the carrier element 4 is made of nylon material and is designed to be wider than the size of the product, so that the product can be stably placed in the discharge trough 41 and has a long service life and is not easy to curl inward; a first adjustment hole 53, a first adjustment platform 51, a second adjustment hole 6, and a second adjustment platform 52 are arranged between the carrier element 4 and the first conveying chain 31 and the second conveying chain 32. When the carrier element 4 is adaptively adjusted in the process of the product with relative posture displacement, the arrangement of the first adjustment hole 53 and the second adjustment hole 6 not only expands the adjustment range of the carrier element 4 but also shares the shear force transmitted by the product to the conveying mechanism 3 parallel to the conveying direction, so that the conveying mechanism is not damaged by the chain during the unloading process of the product, and there is no need to frequently stop the machine for maintenance, thereby improving the stability of transportation.
