Description

Technical Field

[0001] This utility model relates to the field of luggage accessory production equipment, specifically to an assembly structure for a rib removal device for injection-molded luggage handle parts. Background Technology

[0002] The handle of a suitcase is the grip part installed on its pull rod. It has a U-shaped structure and is assembled with the pull rod at both ends. The current production of handle parts is usually carried out by injection molding. In order to improve production efficiency, multi-part injection molding is adopted. During injection molding, flow channel connecting ribs are generated between multiple handle parts to facilitate mold design and product demolding, while ensuring the consistency of material flow of each part during molding.

[0003] The problem with existing technology is that after injection molding, the runner connecting ribs need to be manually cut and separated from the various handle components, and then the handle components need to be collected and stored in an orderly manner for transfer to the subsequent painting and assembly workshops for further processing. Manual operation is not only inefficient, but also requires careful hand protection during the cutting and separation process.

[0004] If automated segmentation equipment is designed to replace manual operation, production efficiency will be significantly improved. However, it is necessary to consider that the shape and size of the handle will change with the production batch. Therefore, the equipment should be able to adapt to the changes in handle components and collect handle components in an orderly manner. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a device for removing the ribs from injection-molded luggage handle parts.

[0006] A further feature of this utility model: a rib removal device for injection-molded luggage handles, comprising a guide rail, a stopping mechanism, and a cutting mechanism. The injection-molded handle includes several handle components and flow channel connecting ribs connecting each handle component. Each handle component has a "U" shaped structure and is provided with a groove for the palm to penetrate deeply. The guide rail includes a base and a pair of guide slides. The pair of guide slides are spaced apart corresponding to the width of the groove. The guide slides are provided with a feeding station, a cutting station, and a discharging station along the axial direction. The guide slides are inclined, with the discharging station located at the lowest point. The stopping mechanism is located vertically below the guide slide bar at the cutting station, and includes an intercepting block and an intercepting cylinder. The intercepting cylinder works in conjunction with the intercepting block to drive the intercepting block to approach the guide slide bar and intercept the handle injection molded part sliding down from the feeding station. The cutting mechanism is located vertically above the guide slide of the cutting station and includes a lifting seat, a lifting cylinder, several limiting blocks, and several cutting tools. The limiting blocks are arranged in an encircling pattern on the lifting seat, and the encircling outline corresponds to the outline of the handle injection molded part that is stopped at the cutting station. The several cutting tools are arranged on the lifting seat corresponding to the connection positions of each handle component and the runner connecting rib, with the cutting edge facing the guide slide. The lifting cylinder is linked with the lifting seat and is signal-activated with the intercepting cylinder. The lifting cylinder drives the lifting seat to move closer to or away from the cutting station. The encircling limiting blocks press down and fix the handle injection molded part, and the cutting tools cut the runner connecting rib. The separated handle components slide along the guide slide to the discharge station for arrangement.

[0007] A further feature of this invention is that each of the pair of guide slide rods is vertically provided with a first support column, and the base is provided with a plurality of first elongated grooves along the width of the groove. The first support column is provided with threads and passes through the first elongated grooves to be fixed with a nut.

[0008] A further feature of this invention is that the flow channel connecting ribs of the injection molded handle are arranged in a fishbone shape, and the plurality of handle components are arranged in two rows mirror images on both sides of the flow channel connecting ribs. The guide rail includes two pairs of guide slide rods corresponding to the two rows of handle components.

[0009] A further feature of this invention is that the lifting seat has several second elongated grooves corresponding to the contour of the handle injection molded part, and the limiting block has a second support column passing through the second elongated groove. The second support column is threaded and passes through the second elongated groove to be fixed with a nut.

[0010] A further feature of this invention is that the lifting seat is provided with several third elongated grooves corresponding to the connection points between each handle component and the flow channel connecting rib. The punching tool is provided with a third support column passing through the third elongated groove. The third support column is threaded and passes through the third elongated groove and is fixed with a nut.

[0011] A further feature of this invention is that the lifting seat is provided with several fourth elongated grooves corresponding to the middle section of each flow channel connecting rib, and a punching tool is provided at each of the fourth elongated grooves.

[0012] Further features of this invention: The base is fixedly connected to the intercepting cylinder and is located vertically below the guide slide rod. The base is provided with a through hole for the piston rod of the intercepting cylinder to pass through and a waste channel corresponding to the cutting station. The flow channel connecting rib of the handle injection molded part falls into the waste channel.

[0013] The beneficial effects of this utility model are as follows: Existing technology uses a robotic arm to grip the injection molded handle part from the injection molding machine. By controlling the robotic arm's movement coordinates, the handle part is positioned at the feeding station of the guide rail, aligning the groove of the handle component with a pair of guide slides. The handle part can then slide along the guide slides to the cutting station. An intercepting block driven by an intercepting cylinder stops the handle part at the cutting station. Then, a signal-linked lifting cylinder drives a lifting seat to approach the handle part. Several surrounding limit blocks press down to fix the handle part. The lifting seat's punching cutter cuts the flow channel connecting ribs, and the separated handle components slide along the guide slides to the discharge station for arrangement.

[0014] The design of the elongated grooves on the base and lifting seat allows the guide slide to adjust to changes in the groove width of the handle component, the limit block to adjust to changes in the overall outline size of the handle injection molded part, and the punching cutter to adjust to changes in the flow channel connecting rib structure design, thereby enabling the punching and separation of handle components of different sizes.

[0015] A punching cutter is installed at the middle section of each flow channel connecting rib to cut the flow channel connecting ribs into finer pieces, so that they fall from the guide slide into the waste channel to complete the separation. The device design of this application enables convenient automated processing of the handle injection molded parts by removing the ribs, and allows for the orderly collection of the separated handle parts for subsequent packaging and transfer processing.
