Description

Technical Field

[0001] This utility model relates to the field of metal coil processing technology, and in particular to a sleeve guiding device. Background Technology

[0002] Currently, in existing cold rolling or finishing production lines for sheet and strip metal, coilers are used to wind up the sheet and strip metal at the discharge end. After the coiler finishes winding up the entire roll of sheet and strip metal, it needs to be unloaded and a new sleeve installed for the next roll. Currently, both the unloading and sleeve installation processes of the coiler use a loading trolley. When placing a new sleeve, an overhead crane is first used to lift the sleeve from the stack on the workshop floor and place it on the V-shaped frame of the loading trolley. The loading trolley then horizontally transports the sleeve to the winding shaft, thus loading the sleeve. However, using an overhead crane to place the sleeve onto the loading trolley results in prolonged crane occupation, and because the sleeve is a round tube, it is not conducive to hoisting, increasing the risk of hoisting accidents. Furthermore, there is a lack of a centralized unloading device for the sleeves.

[0003] Therefore, a sleeve-infeeding device needs to be developed to address the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a sleeve feeding device that collects the sleeves to be loaded and feeds them one by one to the loading trolley according to production needs, without occupying the overhead crane for a long time and with good safety.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model relates to a sleeve guiding device, installed at the feeding end of a winding machine. It includes a base, a sliding frame, an actuating cylinder, a gantry frame, and a sleeve guide mechanism. Multiple sleeves are placed on the base. The sliding frame is slidably connected downwards to an opening on the base facing the winding machine. The actuating cylinder is installed at the bottom of the base, with its piston rod end connected to the bottom of the upper end of the sliding frame. The outward-facing bottom end of the sliding frame is...

[0007] A bottom stop block is provided to block the sleeve; the sleeve blocking mechanism is set above the opening end of the base through the gantry frame, and the sleeve blocking mechanism can release the sleeve one by one.

[0008] Furthermore, rollers are provided on the inner side wall of the base longitudinal beam, and side guide grooves matching the rollers are provided on the outer side wall of the sliding frame longitudinal beam.

[0009] Furthermore, the number of rollers is four, with two rollers arranged as a group on the inner side wall of the base longitudinal beam; the two rollers are respectively arranged in the middle and the open end of the base longitudinal beam; the side guide groove is arranged along the length of the sliding frame.

[0010] Furthermore, the top surfaces of both the base and the sliding frame are inclined, and the top surface of the protruding portion of the sliding frame extends to support the bottom of the top surface of the base; an upper stop is provided at the high end of the top surface of the base to prevent the sleeve from falling upward.

[0011] Furthermore, the baffle mechanism includes an actuating cylinder two, a tilting frame, a rotating rod, and bearing seats. The gantry frame includes two parallel gantry frames arranged front and rear. The bottom of the actuating cylinder two is mounted on the bottom of the crossbeam of the higher gantry frame at the rear via a pin seat. The rotating rod is mounted on the top of the column of the lower gantry frame via bearing seats at both ends. The rotating rod is horizontally arranged and mounted on the tilting frame. The piston rod of the actuating cylinder two is connected to the swing arm on the rotating rod via a pin. The tilting frame can block and release the downward rolling sleeve.

[0012] Furthermore, there are two sets of both the second actuating cylinder and the tilting frame, and they are symmetrically arranged along the vertical center plane of the base.

[0013] Furthermore, the flipping frame is a C-shaped welded structure with the opening facing downwards. The front bottom surface and the rear end surface of the flipping frame are respectively welded with baffle plates, and the baffle plates are in contact with the outer wall of the sleeve. The surface of the baffle plates is coated with a rubber pad layer.

[0014] Furthermore, a proximity switch bracket is installed on the bottom surface of the base longitudinal beam, and a proximity switch is installed on the proximity switch bracket. The proximity switch is electrically connected to the equipment's electrical control system; the bottom surface of the sliding frame...

[0015] The end is connected to a hinge support via an adapter plate, and the proximity switch can detect the position signal of the adapter plate.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] This utility model of a sleeve guiding device utilizes a sliding frame that slides downwards at an angle on the base. This sliding frame transports sleeves downwards to the loading trolley at one end of the winding machine. A sleeve-stopping mechanism installed on the gantry allows sleeves to be released one by one, ensuring that only one sleeve is transported to the V-shaped frame of the loading trolley at a time. This utility model of a sleeve guiding device centrally collects the sleeves to be loaded and feeds them one by one to the loading trolley according to production needs, eliminating the need for long-term occupation of the overhead crane and ensuring good safety.

[0018] Furthermore, the cooperation of rollers and side guide grooves reduces the sliding resistance between the sliding frame and the base. The four symmetrically arranged rollers ensure stable sliding of the sliding frame relative to the base, preventing tilting and overturning. By designing the top surfaces of both the base and the sliding frame as sloped surfaces, multiple sleeves arranged side-by-side can roll down under their own weight after the stop mechanism is activated, without the need for an additional pushing mechanism. The sleeves are released one by one by using a rotating rod to drive the tilting frame. The second actuating cylinder drives the tilting frame to swing repeatedly, releasing one sleeve with each swing, coordinating with the sliding frame's movement to load the sleeves. The two sets of actuating cylinders and the tilting frame create synchronous blocking and release at both ends of the sleeves, ensuring a smooth downward roll without tilting or overturning. The composite rubber pad on the stop plate surface reduces collision and scratch damage to the sleeve surface during the tilting frame's operation. By adding two proximity switches to the bottom surface of the base longitudinal beam, the position signal of the sliding frame can be detected, and two extreme positions are defined as the retraction preparation position and the ejection feeding position, which ensures that the feeding position is accurate and enters directly above the loading trolley.

[0028] The core of this utility model is to provide a sleeve feeding device that collects the sleeves to be loaded and feeds them one by one to the loading trolley according to production needs, without occupying the overhead crane for a long time and with good safety.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0031] This implies that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main structure of the sleeve inlet device of this utility model; Figure 2 This is a schematic diagram of the left side of the sleeve inlet device of this utility model; Figure 3 This is a top view of the sleeve inlet device of this utility model; Figure 4 This is a schematic diagram of the main structure of the sleeve feeding device of this utility model in the sleeve feeding state; Figure 5 This is a schematic diagram of the main structure of the base of this utility model; Figure 6 This is a schematic diagram of the main structure of the sliding frame of this utility model; Figure 7 for Figure 1 A magnified schematic diagram of the structure of part I in the middle.

[0033] In one specific implementation, such as Figures 1-7As shown, the sleeve guiding device of this utility model is installed at the feeding end of the winding machine, including a base 1, a sliding frame 2, an actuating cylinder 3, a gantry frame 4, and a sleeve blocking mechanism. The base 1 is a welded C-shaped frame, and multiple sleeves 9 are placed on the top surface of the base 1. The sliding frame 2 is inclined downward and slidably connected to the opening of the base 1 facing the winding machine. The actuating cylinder 3 is installed at the bottom of the base 1, and the piston rod end is connected to the bottom of the upper end of the sliding frame 2. A bottom stop block 205 is provided at the outward-facing bottom end of the sliding frame 2 to block the sleeves 9, preventing the bottommost sleeve 9 from rolling downward. The sleeve blocking mechanism is set above the opening end of the base 1 via the gantry frame 4, and the sleeve blocking mechanism can release the sleeves 9 one by one.

[0034] By installing a downward-sliding sliding frame 2 on the base 1, the sliding frame 2 can convey the sleeves 9 downwards to the loading trolley at one end of the winding machine; by installing the sleeve-stopping mechanism on the gantry frame 4, the sleeves 9 can be released one by one, ensuring that only one sleeve 9 is conveyed to the V-shaped frame of the loading trolley at a time by the sliding frame 2. This utility model sleeve guiding device centrally collects the sleeves to be loaded and feeds them one by one to the loading trolley according to production needs, eliminating the need for long-term occupation of the overhead crane and ensuring good safety.

[0035] In one specific embodiment of this utility model, such as Figures 1-6 and Figure 7 As shown, rollers 103 are provided on the inner side wall of the longitudinal beam of the base 1, and a side guide groove 201 matching the rollers 103 is provided on the outer side wall of the longitudinal beam of the sliding frame 2. The side guide groove 201 is inclined with the outer side lower and the inner side higher. In a specific embodiment, the side guide groove 201 is welded together with the frame longitudinal beam of the sliding frame 2.

[0036] Specifically, such as Figure 7 As shown, the roller 103 is mounted on the inner side wall of the longitudinal beam of the base 1 via a bearing and a short shaft, and the outer contour of the roller 103 is adapted to the cross-sectional contour of the side guide groove 201.

[0037] Specifically, such as Figures 1-5 As shown, there are four rollers 103, arranged in groups of two on the inner wall of the longitudinal beam of the base 1. The two rollers 103 are respectively located at the middle and open end of the longitudinal beam of the base 1. The side guide groove 201 extends continuously along the length of the sliding frame 2. Specifically, detachable stop pins or baffles can also be provided at both ends of the side guide groove 201 to prevent the sliding frame 2 from detaching from the base 1 when it moves beyond its limit position.

[0038] The cooperation of rollers 103 and side guide grooves 201 reduces the sliding resistance between the sliding frame 2 and the base 1. At the same time, the four symmetrically arranged rollers 103 ensure that the sliding frame 2 slides stably relative to the base 1 without tilting or overturning.

[0039] In one specific embodiment of this utility model, such as Figure 1 and Figures 4-6 As shown, the top surfaces of both the base 1 and the sliding frame 2 are inclined, and the protruding part of the sliding frame 2 extends to support the top surface of the base 1. An upper stop 101 is provided at the high end of the top surface of the base 1 to prevent the sleeve 9 from falling upwards. Multiple sleeves 9 are arranged side-by-side on the inclined top surface of the base 1.

[0040] By setting the top surfaces of both the base 1 and the sliding frame 2 to be inclined, it can be ensured that multiple sleeves 9 arranged side by side will roll down by their own gravity after the baffle mechanism is activated, without the need for an additional pushing mechanism.

[0041] In one specific embodiment of this utility model, such as Figures 1-4 The stop mechanism includes an actuating cylinder 5, a tilting frame 6, a rotating rod 7, and bearing seats 8. The gantry frame 4 includes two parallel gantry frames, both vertically arranged. The bottom of the actuating cylinder 5 is mounted to the bottom of the crossbeam of the higher gantry frame via a pin. The rotating rod 7 is mounted to the top of the column of the lower gantry frame via bearing seats 8 at both ends; the rotating rod 7 is horizontally positioned and mounted on the tilting frame 6. The piston rod of the actuating cylinder 5 is connected to the swing arm 701 on the rotating rod 7 via a pin. The tilting frame 6 can block and release the downward-rolling sleeve 9.

[0042] Obviously, the stop cylinder mechanism can also be achieved by installing two stop gates on two gantry frames respectively, with the distance between the two gates being exactly the diameter of a sleeve 9. By having the two gates work alternately to release the sleeves 9 one by one, a similar technical effect can be achieved. This simple replacement of the technical solution also falls within the protection scope of this utility model.

[0043] Specifically, such as Figures 1-4 As shown, there are two sets of the second action cylinder 5 and the tilting frame 6, which are symmetrically arranged along the vertical center plane of the base 1.

[0044] Specifically, such as Figures 1-4 As shown, the tilting frame 6 is a C-shaped welded structure with the opening facing downwards. A baffle plate 601 is welded to the front bottom surface and the rear end surface of the tilting frame 6, respectively. The baffle plate 601 contacts the outer wall of the sleeve 9. A rubber pad layer is laminated to the surface of the baffle plate 601, and the rubber pad layer is installed by adhesive bonding.

[0045] The sleeves 9 are released one by one by using a rotating rod 7 to drive the tilting frame 6 to tilt. The second actuating cylinder 5 drives the tilting frame 6 to swing repeatedly, releasing one sleeve 9 with each movement. This, combined with the movement of the sliding frame 2, enables the sleeves 9 to be fed. The two sets of actuating cylinders 5 and the tilting frame 6 create synchronous blocking and release at both ends of the sleeves 9, ensuring that the sleeves 9 roll smoothly downwards without tilting or tipping over. The composite rubber pad on the surface of the blocking plate 601 reduces collision and scratch damage to the surface of the sleeves 9 during the movement of the tilting frame 6.

[0046] In one specific embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, a proximity switch bracket 102 is mounted on the bottom surface of the longitudinal beam of the base 1, and a proximity switch is mounted on the proximity switch bracket 102. The proximity switch is electrically connected to the equipment's electrical control system. The front end of the bottom of the sliding frame 2 is connected to a hinge support 204 via an adapter plate 203, and the proximity switch can detect the position signal of the adapter plate 203.

[0047] By adding two proximity switches to the bottom surface of the longitudinal beam of the base 1, the position signal of the sliding frame 2 can be detected, and two extreme positions are defined as the retraction preparation position and the ejection feeding position, which ensures that the feeding position is accurate and enters directly above the loading trolley.

[0048] The working process of the sleeve guiding device of this utility model is as follows: Figures 1-4 As shown, the metal strip on the unwinding machine

[0049] After the material roll is collected, it is unloaded by the loading trolley and transported to the unloading position. After unloading, the loading trolley moves to the front of the sleeve guide device of this utility model. The piston rod of the second cylinder 5 retracts, the tilting frame 6 tilts backward, the bottom sleeve 9 is released and rolls to the front end of the sliding frame 2 and is blocked by the bottom stop 205, and the second to last sleeve 9 is blocked by the blocking plate 601 at the rear end of the tilting frame 6. The first cylinder 3 is activated, the piston rod retracts, the sliding frame 2 slides forward and downward, the proximity switch at the front end detects the position signal of the adapter plate 203, and the sliding frame 2 enters the top feeding position. The bottom sleeve 9 is transported to the top of the loading trolley, that is, directly above the V-shaped frame. The loading trolley pushes upward, the V-shaped frame lifts the bottom sleeve 9 and detaches it from the sliding frame 2. The piston rod of the first cylinder 3 pushes out, and the sliding frame 2 returns to the return preparation position. When the piston rod of cylinder 5 extends, the tilting frame 6 tilts forward, and the bottom sleeve 9 rolls forward a short distance and enters directly below the tilting frame 6. Then, the piston rod of cylinder 5 retracts, the tilting frame 6 tilts backward, and the bottom sleeve 9 is released and rolls to the front end of the sliding frame 2, where it is stopped by the bottom stop block 205. Preparation for the next feeding.

[0050] In summary, this utility model's sleeve guiding device, by setting an inclined downward sliding frame 2 on the base 1, can convey sleeves 9 downward to the loading trolley at one end of the winding machine; by installing the aforementioned baffle mechanism on the gantry frame 4, sleeves 9 can be released one by one, ensuring that only one sleeve 9 is conveyed to the V-shaped frame of the loading trolley at a time by the sliding frame 2. This utility model's sleeve guiding device centrally collects the sleeves to be loaded and feeds them one by one to the loading trolley according to production needs, eliminating the need for long-term occupation of the overhead crane and ensuring good safety. In addition, the cooperation of the rollers 103 and the side guide grooves 201 reduces the sliding resistance between the sliding frame 2 and the base 1, and the four symmetrically arranged rollers 103 ensure that the sliding frame 2 slides stably relative to the base 1, without tilting or overturning. By setting the top surfaces of both the base 1 and the sliding frame 2 to be inclined, multiple sleeves 9 arranged side by side can be ensured to roll down under their own gravity after the baffle mechanism is activated, without the need for an additional pushing mechanism. The sleeves 9 are released one by one by using a rotating rod 7 to drive the tilting frame 6 to tilt. The second cylinder 5 drives the tilting frame 6 to swing repeatedly.

[0051] Each action releases one sleeve 9, coordinating with the movement of the sliding frame 2 to load the sleeve 9. The two sets of actuating cylinders 5 and the tilting frame 6 create synchronized blocking and release at both ends of the sleeve 9, ensuring its smooth downward roll without tilting or tipping. The composite rubber pad on the surface of the blocking plate 601 reduces impact and scratch damage to the sleeve 9 surface during the tilting frame 6's movement. By adding two proximity switches to the bottom surface of the longitudinal beam of the base 1, the position signal of the sliding frame 2 can be detected, defining two extreme positions: the retraction preparation position and the ejection feeding position, ensuring accurate feeding directly above the loading trolley.
