Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, specifically to a multi-bar automatic feeding, cutting, self-closing, stacking, and counting system. Background Technology

[0002] Currently, in the field of long bar cutting, individual operations are usually performed using various devices. For example, the cutting operation is carried out using the "A Bar and Tube Cutting Production Line" disclosed in Publication No. CN117754340A, and the stacking operation after cutting is carried out using the "A Copper and Aluminum Rod and Profile Stacking Device" disclosed in Publication No. CN210480127U. The equipment integration is not high, the functions are limited, and it cannot meet the diversified production needs.

[0003] A search revealed no production line that integrates feeding, conveying, automated precision cutting, chip removal, marking, and stacking functions. In particular, existing equipment typically only feeds one bar stock at a time, making it impossible to simultaneously feed and cut multiple bars, primarily due to difficulties in control.

[0004] Based on this, the present utility model is proposed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an automatic multi-bar feeding, cutting, self-closing, stacking, and counting system. The technical solution is as follows:

[0006] The multi-bar automatic feeding, cutting, self-compacting stacking, and counting system includes a chain conveyor for transporting bar stock, a mobile lifting trolley, an alignment pusher, a yielding feed roller conveyor, a front-fixed gripper pushing mechanism, a cutting mechanism, an discharge roller conveyor, a self-compacting stacking system, and a counting and lifting platform. Bar stock on several chain conveyors is aligned by the alignment pusher and then transported by the mobile lifting trolley to the yielding feed roller conveyor. The bar stock on the yielding feed roller conveyor is driven forward by the front-fixed gripper pushing mechanism to the cutting mechanism for cutting. The cut bar stock is then transported by the discharge roller conveyor to the self-compacting stacking and counting and lifting platform for automatic arrangement, stacking, and counting.

[0009] As a further embodiment of this invention, it also includes a positioning fixture for stacking the stacked bar stock.

[0010] As a further embodiment of this utility model, the alignment pusher includes a pusher plate, a fixed plate, a mounting frame for mounting the pusher plate and the fixed plate, and a guide cylinder for driving the pusher plate to perform reciprocating translational motion.

[0011] As a further embodiment of this utility model, the yielding feed roller conveyor includes a frame and multiple sets of lifting support rollers mounted on the frame. Each lifting support roller includes a roller shaft, side retaining rings respectively mounted at both ends of the roller shaft, a support plate for fixed connection with the side retaining rings, a crankshaft located below the roller shaft, a crank, and a cylinder. The cylinder seat of the cylinder is hinged to the frame, the telescopic end of the cylinder is hinged to one end of the crank, the other end of the crank is fixedly connected to the middle of the crankshaft, the end of the crankshaft is rotatably connected to the frame via a bearing, and the end of the crankshaft is fixedly connected to the lower end of the support plate.

[0012] As a further embodiment of this utility model, the front fixed gripper pushing mechanism includes a rack-type guide rail base arranged along the forward direction of the feed roller conveyor and two front fixed grippers.

[0021] The present invention will be described in detail below with reference to specific embodiments. These embodiments are merely some, not all, implementations of the present invention. All other implementations obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1-3 As shown, the multi-bar automatic feeding, cutting, self-compacting stacking, and counting system includes a chain conveyor 10 for transporting bar stock, a mobile lifting trolley 20, an alignment pusher 30, a yielding feed roller conveyor 50, a front-fixed gripper pushing mechanism, a cutting mechanism 60, an discharge roller conveyor 70, and a self-compacting stacking and counting lifting platform 80. Bar stock on several chain conveyors 10 is aligned by the alignment pusher 30 and then transported by the mobile lifting trolley 20 to the yielding feed roller conveyor 50. The bar stock on the yielding feed roller conveyor 50 is driven forward by the front-fixed gripper pushing mechanism to the cutting mechanism 60 for cutting. The cut bar stock is then transported by the discharge roller conveyor 70 to the self-compacting stacking and counting lifting platform 80 for automatic arrangement, stacking, and counting.

[0024] The alignment pusher plate 30 is used to align all the bars at the end of the chain conveyor 10, and then the mobile lifting trolley 20 is used to transport them onto the yielding feed roller conveyor 50.

[0025] The mobile lifting trolley 20 includes a guide rail base 21 and a lifting trolley 22 that moves back and forth along the guide rail base 21. The lifting trolley 22 is used to lift and lower the bar stock.

[0026] Based on the layout of the production line and the rational design of the movement, the forward direction of the chain conveyor 10 is perpendicular to the forward direction of the yielding feed roller conveyor 50, and the forward direction of the discharge roller conveyor 70 is parallel to the forward direction of the yielding feed roller conveyor 50.

[0027] The alignment push plate 30 includes a push plate 31, a fixed plate 32 arranged along the forward direction perpendicular to the chain conveyor 10, a mounting bracket 34 for mounting the push plate 31 and the fixed plate 32, and a guide cylinder 33 for driving the push plate 31 to perform reciprocating translational motion.

[0028] The guide cylinder 33, which operates with greater precision and stability, drives a single pusher plate 31 to push, thereby enabling the alignment pusher plate 30 to perform its function of aligning multiple bars.

[0029] The yielding feed roller conveyor 50 includes a frame 54 and multiple sets of lifting support rollers mounted on the frame 54. Each lifting support roller includes a roller shaft 51, side retaining rings 52 respectively mounted at both ends of the roller shaft 51, a support plate 55 for fixed connection with the side retaining rings 52, a crank shaft 53 located below the roller shaft 51, a crank 56, and a cylinder 57. The cylinder seat of the cylinder 57 is hinged to the frame 54, the telescopic end of the cylinder 57 is hinged to one end of the crank 56, the other end of the crank 56 is fixedly connected to the middle of the crank shaft 53, the end of the crank shaft 53 is rotatably connected to the frame 54 by a bearing, and the end of the crank shaft 53 is fixedly connected to the lower end of the support plate 55.

[0030] Traditional roller conveyors often use screw lifting for adjustment. This invention replaces this with segmented control, with each segment controlled by a cylinder 57 connected to a CNC center for segment-by-segment control. Furthermore, this invention employs a "side-lying" lifting mechanism, allowing the roller conveyor to provide both clearance and support. Specifically, the cylinder 57 drives the crank 56, rotating the crankshaft 53. This rotation, in turn, drives the roller shaft 51 around the bearing via the support plate 55, achieving small-amplitude lifting. This lifting method is smoother, more suitable for simultaneous movement of multiple bars, and facilitates segment-by-segment control.

[0031] The front fixed gripper pushing mechanism includes a rack and pinion guide base 41 arranged along the forward direction of the feed roller conveyor 50 and two front fixed grippers 42. The two front fixed grippers 42 perform translational reciprocating motion along the direction defined by the rack and pinion guide base 41. The two front fixed grippers 42 include a lifting gripper head and a gripper seat. The lifting gripper head includes an upper clamping plate, a lower clamping plate and a rear baffle.

[0032] Existing technologies mostly use rear-mounted grippers, which may result in material loss or misalignment during cutting. In this invention, a front-mounted gripper is used, which is more precise and allows multiple pieces of material to be fed at the same time, improving efficiency. By raising and lowering the gripper head, and then using the upper clamping plate, lower clamping plate, and rear baffle, the gripping position on three sides is controlled simultaneously from the top, bottom, and rear, ensuring that materials of various specifications and quantities can be clamped.

[0033] As multiple bars are aligned for the first time by the alignment pusher plate 30, and then aligned again by the two front fixed grippers 42, the multiple bars on the feed roller conveyor 50 are driven by the two front fixed grippers 42 in a "push" manner, and driven to the cutting mechanism 60 for cutting. The cut bars are then transported to the self-closing stacking and counting lifting platform 80 through the discharge roller conveyor 70 for automatic arrangement, stacking and counting.

[0034] The self-closing palletizing and counting lifting platform 80 includes a lifting limit plate, palletizing equipment, marking machine and counter.

[0035] Because the cut bar stock needs to be automatically and neatly stacked for marking, it must be arranged in a single, orderly row. A lifting limit plate at the top restricts the height of only one row. A palletizing device that moves along the platform pushes the stock into this neat arrangement. The palletizing device can be a three-axis / six-axis robot or a gantry-type robotic arm. This neat arrangement of the bar stock facilitates subsequent marking. After marking, the stock moves to a temporary storage table, then to the unloading table, where a counter determines the quantity based on the diameter, allowing for easy retrieval of the corresponding quantity.

[0036] Example 2

[0037] The automatic multi-bar feeding, cutting, self-closing, stacking, and counting system also includes a positioning fixture 90 for stacking the stacked bars. After counting, the stacked bars are placed in the positioning fixture 90, awaiting the next process.

[0038] Example 3

[0039] The cutting mechanism 60 is also equipped with a chip suction machine 61 at the cutting point to remove the cutting debris.

[0040] The chip removal machine 61 removes the waste chips from the cutting process and processes them centrally.

[0041] Furthermore, it should be understood that those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
