Description

Technical Field

[0001] The utility model relates to the field of conveying equipment for workpiece production and processing, in particular to automatic sorting and feeding equipment for metal pipe fittings. Background Art

[0002] As an important industrial raw material, metal pipe fittings are widely used in various fields, including petrochemical, shipbuilding, electricity, natural gas, medicine and food, water conservancy technology, and construction. In these fields, metal pipe fittings are mainly used to connect, transport and control various media, such as liquids, gases and electricity. In addition, metal pipe fittings are processed into products such as welding pipe fittings, socket welding, threaded pipe fittings, flange pipe fittings, etc., which are used to build and maintain various systems and equipment. In the process of producing these products, there is usually a stage in which the hollow slender rod-shaped raw material is first cut into a shorter tubular workpiece that meets the processing requirements of stamping or extrusion equipment before the subsequent processing process can be carried out. For these metal pipe fittings that are randomly stacked after the initial cutting process, some special equipment is needed to grab and arrange them so that they can be processed efficiently.

[0003] Currently, there are some devices that can perform corresponding processing on such tubular members. For example, a Chinese utility model patent document with application number CN201310175969.8 discloses an automatic discharging and feeding device for pipe fittings, comprising a discharging mechanism capable of embedding pipe fittings, a driving mechanism capable of driving the displacement of pipe fittings on the discharging mechanism, and a feeding mechanism capable of grabbing and conveying pipe fittings on the discharging mechanism, wherein the discharging mechanism has two side-by-side chain rings, which are jointly mounted on two side-by-side main shafts through a set of sprockets, and the two chain rings respectively fix a plurality of pairs of pipe fitting clamps capable of embedding the same pipe fittings, and the driving mechanism is mounted on one of the main shafts, comprising a ratchet wheel fixed to the main shaft, a ratchet fixing plate with one end movably sleeved on the main shaft and parallel to the ratchet wheel, and a driving cylinder capable of driving the other end of the ratchet fixing plate to reciprocate, and the ratchet fixing plate is also provided with a ratchet wheel capable of unidirectionally meshing with the ratchet wheel and driving the ratchet wheel to rotate in conjunction with the main shaft, and the feeding mechanism comprises two supporting dies and a feeding cylinder capable of driving the two supporting dies to push out the pipe fittings on the corresponding pipe fitting clamps. The device can realize continuous placement of pipe fittings and can automatically deliver the pipe fittings, thereby improving work efficiency and reducing labor intensity.

[0004] However, the applicant found that in the equipment similar to the above scheme, a grabbing method is used to arrange and load the pipes as raw materials or products. However, for some smooth-surfaced raw material sections of pipes such as metal, since the metal pipes themselves have a large weight and a very smooth surface, they are prone to slipping and falling off during the grabbing process. At the same time, since the above equipment adopts a grabbing material collection method, the raw materials need to be sorted and combed before processing, which greatly increases the labor input and reduces production efficiency.

[0005] In view of the above problems, the utility model provides an automatic sorting and feeding equipment for metal pipe fittings. In view of the fact that the metal pipe fittings used as raw materials have smooth surfaces and are difficult to grasp, and even when these metal pipe fittings are stacked and placed in a disorderly manner, they can be automatically and efficiently sorted and fed without prior arrangement, thereby greatly reducing labor input and improving the feeding effect.

[0030] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0031] This solution is achieved through the following technical means:

[0032] Embodiment: In this embodiment, an automatic sorting and feeding device for metal pipes is provided. In view of the smooth surface and difficult-to-grasp characteristics of metal pipes as raw materials, and even when these metal pipes are stacked and placed in a disorderly manner, they can be automatically and efficiently sorted and fed without prior arrangement, which greatly reduces the labor input and improves the feeding effect. From the perspective of functional structure, the device includes an arranging and sorting mechanism 1 for taking out individual workpieces 7 from a pile of materials in sequence, and a positioning and feeding mechanism 2 for pushing the workpieces 7 into a specific extrusion work position in the extrusion equipment. A transfer and conveying mechanism 3 for moving the workpiece 7 between the two mechanisms is also provided between the arranging and sorting mechanism 1 and the positioning and feeding mechanism 2.

[0033] Specifically, the structure of the device can refer to the attached manual. Figure 1 As shown, a detailed description will be given. First, the arrangement and sorting mechanism 1 mentioned above mainly includes a hopper 101 located at the bottom position close to the ground. The hopper 101 is open upward and is in the shape of a hopper that contracts from top to bottom. A groove is provided at the bottom position in the center of the hopper 101, and the groove extends upward and protrudes to the edge of the hopper 101, and a chain plate assembly 102 is fixedly installed at the groove. The chain plate assembly 102 here includes a movable chain plate 103 and a driving device 104, wherein the movable chain plate 103 is formed by a plurality of section plates that are connected to each other by hinges to form a ring shape, and a rotating shaft is installed at the bottom of the aforementioned groove and at its upper end, respectively, and the movable chain plate 103 surrounds the two rotating shafts and can perform conveying movement following the rotation of the rotating shaft. The driving device 104 here can be realized by using a stepper motor. It only needs to connect the aforementioned rotating shaft arranged on the output shaft through a gear assembly or a coupling to realize the continuous rotating motion of the movable chain plate 103 in the power-on state. It should also be noted that since the cross-section of the workpiece 7 to be transported and moved is a smooth circle, an outer convex extension 105 for supporting and pushing the workpiece 7 needs to be formed on each section plate. As each section plate moves upward along the moving direction of the movable chain plate 103, the outer convex extension 105 will first perform a translational motion at the bottom of the hopper 101, and then gradually change into an upward lifting motion. In this process, only a workpiece 7 that is exactly engaged between the two section plates can be separated and taken out from the material pile, and gradually moves upward with the section plates. For those workpieces 7 with deviations in position, they will fall back into the hopper 101 and wait for the subsequent material collection process.

[0034] At the rear side of the upper part of the arrangement and sorting mechanism 1, a transfer and conveying mechanism 3 is provided for moving the workpieces 7 screened out one by one from the hopper 101 by the arrangement and sorting mechanism 1 to the next processing mechanism. The transfer and conveying mechanism 3 includes a conveyor belt assembly 301 capable of pushing and conveying the workpiece 7 to one side in the horizontal direction, and a transition guide plate 302 provided between the upper rear side of the chain plate assembly 102 and the front section of the conveyor belt assembly 301. The conveyor belt assembly 301 here is in an inclined shape with the front higher and the back lower, and an upright blocking plate 4 is also provided at the rear side of the conveyor belt assembly 301 to play a role of abutting and blocking the workpiece 7 located on the conveyor belt assembly 301. Then, when a workpiece 7 is lifted to the top flip position along with the aforementioned conveyor chain plate, the metal pipe fitting used as the conveying workpiece 7 will slide down under the action of its own gravity and separate from the section plate, and fall onto the transition guide plate 302. With the guidance of the inclined transition guide plate 302, the cylindrical tubular workpiece 7 will continue to roll and fall onto the conveyor belt in the conveyor belt assembly 301. Since the conveyor belt assembly 301 also has a certain inclination angle, the workpiece 7 will move forward along the conveyor belt while the side surface is continuously abutted by the aforementioned blocking plate 4.

[0035] Here, the inventor also considers that when the workpiece 7 falls onto the surface of the conveyor belt, it is still possible that due to the instability of the operation of the previous mechanism or the excessively fast one-time material dropping speed, at least two workpieces 7 may be moved with the conveyor belt in a state of being stacked and interlaced with each other. In such a conveying state, the workpiece 7 cannot be accurately allowed to enter the processing position, and further control and processing of the workpiece 7 in this state is required. Therefore, as a preferred structure, on the basis of the above structure, a screening material shifting rod 401 protruding outward is formed on the blocking plate 4, and the screening material shifting rod 401 can shift outward the upper workpiece 7 of the two workpieces 7 stacked on each other on the conveyor belt assembly 301; at the same time, a return material guide plate 5 is also provided between the conveyor belt assembly 301 and the hopper 101, which can guide the workpiece 7 shifted outward by the screening material shifting rod 401 and separated from the conveyor belt assembly 301 and make it fall back into the hopper 101.

[0036] The automatic sorting and feeding equipment for metal pipes provided in this embodiment is located at the rear side, and is used to finally position and place the cylindrical pipe-shaped workpiece 7 on a movable mechanism, and then feed it into the interior of the extrusion molding equipment, and then undergo the final processing of the molding equipment to obtain the final processed and molded parts or semi-finished products. Figure 4In the structure shown, the positioning feeding mechanism 2 is arranged at the rear end of the conveyor belt assembly 301, which includes a support bracket 201 that plays a supporting and fixing role, and a sliding feeding frame 202 that is movably arranged on the support bracket 201. A guide rail mechanism 204 is formed between the sliding feeding frame 202 and the support bracket 201, and a drag chain assembly or a cylinder device can be used as a power source to drive the sliding feeding frame 202 to move, so that the sliding feeding frame 202 can move back and forth in the horizontal direction, and the front end of the sliding feeding frame 202 is formed with a receiving slot 203 for inserting the workpiece 7, and the opening of the receiving slot 203 is opposite to the rear end of the conveyor belt assembly 301. In this embodiment, with reference to the drawings of the specification, a structure of two parallel rows of receiving slots 203 is designed here. Of course, according to the working efficiency and requirements of the actual equipment, a three-row or more arrangement structure can also be adopted.

[0037] Further preferably, a discharge guide rail 6 for guiding the pressed product outward is fixedly installed on the top of the positioning and feeding mechanism 2, and is used to receive the extruded finished product or semi-finished component and guide it to fall.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
