Description

Technical Field

[0001] The utility model relates to the technical field of plate moving, in particular to a small plate feeding device. Background Art

[0002] The frame of the tricycle is mainly welded with various square tubes, angle steels, plates, etc. The square tube is mainly used to produce the frame part of the frame, and the angle steel is used to support or connect the frame part. The square tube and angle steel are used after being cut into the designed length, and the plate is used after shearing or CNC cutting. Among them, the raw materials of the square tube and angle steel are generally of uniform length, such as 6m or 8m, and the required design length is not fixed, so after cutting the square tube or angle steel of the designed length, it is inevitable to produce various lengths of surplus. These surpluses are difficult to be used in the production of the frame, and are mainly treated as waste in the later stage, which will form a waste of resources and is not conducive to production cost control. The plates used are mostly plates with a thickness of about 2mm. This kind of plate is easy to bend due to its own weight, so in production, it is generally cut into specified small-sized plates by a shearing machine, and then the small plates are moved to a CNC cutting machine for cutting or other machining processes for further processing. This kind of small plate with a thickness of about 2mm is mostly 1 to 3m long, 0.5 to 2m wide, and weighs from a dozen to dozens of kilograms. It is difficult to move it manually, so only mechanical assistance can be considered. The existing permanent magnetic lifter is not convenient to use in this small plate loading occasion because it is easy to absorb multiple plates in the stack at one time and the shaking problem is obvious during the moving process. The inventor tends to use a multi-point negative pressure adsorption loading device to load this small plate, but this kind of special loading device that can be adapted to small plates within the above size range is not easy to purchase on the market. For this reason, the inventor combined the actual situation of existing materials in the production process and designed and manufactured a loading device that is convenient to use pipe surplus materials and can be adapted to small plates of multiple sizes for loading, in order to optimize production cost control while facilitating the auxiliary loading of small plates. This invention was born. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0022] like Figures 1 to 7 As shown in the figure, the small plate feeding device includes a longitudinal main pipe 1 made of a square tube, and the longitudinal main pipe 1 provides a structural layout space for adsorption in the length direction of the small plate. The length of the longitudinal main pipe 1 is set according to the maximum length of the small plate to be adsorbed, and specifically, the length of the unadsorbed end of the small plate in the length direction does not have a droop that affects the movement. If the longest length of the small plate is about 3m, and the droop of the 2mm thick plate does not affect the movement when the longest length is about 0.6m or less, then the longitudinal main pipe 1 can be designed to be 1.8m long.

[0023] The longitudinal main pipe 1 includes an intermediate pipe 11 and extension pipes 12 located at both ends of the intermediate pipe 11. Accordingly, the longitudinal main pipe 1 is composed of three sections, and the total length of 1.8m can be divided into three square tubes of no more than 1m, which is convenient for making with pipe scraps. A plug-in pipe 13 is fixedly welded inside the extension pipe 12, and the part of the plug-in pipe 13 extending out of the extension pipe 12 is inserted into the intermediate pipe 11. The extension pipe 12 and the intermediate pipe 11 are connected by the plug-in pipe 13. The plug-in pipe 13 is a square tube with an outer side length equal to or slightly less than the inner side length of the intermediate pipe 11 and the extension pipe 12 to achieve reliable plug-in. The principle of the set fit that appears later in this embodiment is equivalent to this, and will not be repeated later. The lap length between the plug-in pipe 13 and the extension pipe 12 and the intermediate pipe 11 is small, and a shorter length can be achieved, which is also convenient for making with pipe scraps.

[0024] A plug-in limiting structure 14 is provided between the plug-in tube 13 and the intermediate tube 11, and the plug-in limiting structure 14 enables the extension tube 12 and the intermediate tube 11 to be reliably maintained as an integral longitudinal main tube 1. The plug-in limiting structure 14 in this embodiment includes a limiting installation hole 15 provided on the side wall of the plug-in tube 13, a limiting installation nut 16 is welded at the inner end of the limiting installation hole 15 on the plug-in tube 13, a plug-in limiting screw 17 with its head located at the outer end of the limiting installation hole 15 is installed on the limiting installation nut 16, and a plug-in limiting hole 18 with its head matched with the head of the plug-in limiting screw 17 is provided on the intermediate tube 11.

[0025] After the plug-in tube 13 is inserted into the intermediate tube 11, the limit installation hole 15 and the plug-in limit hole 18 are aligned, and the plug-in limit screw 17 is screwed into the limit installation nut 16 through the plug-in limit hole 18 until the head thereof abuts against the outer end of the limit installation hole 15. At this time, the head of the plug-in limit screw 17 is in the plug-in limit hole 18, forming a boss that blocks the plug-in limit hole 18, and the withdrawal of the plug-in tube 13 from the intermediate tube 11 is restricted, and the extension tube 12 forms a reliable connection with the intermediate tube 11. Of course, the head of the plug-in limit screw 17 should not protrude or not obviously protrude from the outer surface of the intermediate tube 11, so that the intermediate tube 11 and the extension tube 12 can form a longitudinal main tube 1 with a relatively flat outer surface together, so as to facilitate the position adjustment of the structure thereon. The plug-in tube 13 is provided with a welding avoidance 19 for conveniently welding the limit installation nut 16.

[0026] At least two cross - tube mounting sleeves 2 are sleeved on the longitudinal main tube 1, and a longitudinal position positioning structure 21 is provided on the cross - tube mounting sleeve 2. The longitudinal position positioning structure 21 is realized by radial bolts. By loosening the radial bolts, the cross - tube mounting sleeve 2 can change its position on the longitudinal main tube 1, and by re - tightening the radial bolts, the cross - tube mounting sleeve 2 is fixed at a specified position, thereby realizing the adjustment of the longitudinal position, which is convenient for adapting to small plate members of different lengths for use; the above - mentioned radial bolt means belongs to the common means in the pipe - shaft fit and is well - known to those skilled in the art, so it will not be elaborated here. The length of the cross - tube mounting sleeve 2 is very short, and it is also convenient to be made of the remaining materials of the pipe.

[0027] A transverse tube 3 that intersects with the longitudinal main tube 1 is fixedly welded on the cross - tube mounting sleeve 2. The transverse tube 3 provides a structural layout space for adsorption in the width direction of the small plate member. Its length is also set according to the maximum width dimension of the small plate member to be adsorbed. For example, if the maximum width of the small plate member is about 2m, and based on the fact that for a 2 - mm - thick plate with a length of about 0.6m or less, the sag does not affect the handling, so the length of the transverse tube 3 can be set to 0.8m. A length less than 1m is also convenient to be made of the remaining materials of the pipe. In this embodiment, there are three cross - tube mounting sleeves 2, so the main body composed of the longitudinal main tube 1 and the transverse tube 3 is arranged in a shape like the Chinese character "丰" (feng).

[0028] Adsorption mounting sleeves 4 are respectively sleeved on both sides of the longitudinal main tube 1 on the transverse tube 3, and a transverse position positioning structure 41 is provided on the adsorption mounting sleeve 4. The transverse position positioning structure 41 is also realized by radial bolts and will not be elaborated here; through this transverse position adjustment, it is convenient to adapt to small plate members of different widths for use. The length of the adsorption mounting sleeve 4 is also very short, and it is also convenient to be made of the remaining materials of the pipe.

[0029] An adsorption assembly 5 is respectively provided on each adsorption mounting sleeve 4. The adsorption assembly 5 is used to adsorb the small plate member. The adsorption assembly 5 includes an adsorption guide tube 51 fixedly welded on the adsorption mounting sleeve 4. An adsorption guide bolt 52 is vertically slidably mounted on the adsorption guide tube 51. The head of the adsorption guide bolt 52 is restricted to be arranged at the upper end of the adsorption guide tube 51. A suction cup 53 is fixedly installed at the lower end of the adsorption guide bolt 52. An adsorption buffer spring 54 is sleeved on the adsorption guide bolt 52 between the suction cup 53 and the adsorption guide tube 51.

[0030] When not adsorbing, the suction cup 53 is kept at the lowest position under the action of its own weight and the adsorption buffer spring 54, and the head of the adsorption guide bolt 52 abuts against the upper end surface of the adsorption guide tube 51, forming a position limit for this lowest position. When adsorbing, the suction cup 53 descends to the surface of the small plate with the main body, and is pressed down by the weight of the main body, etc. At this time, the adsorption buffer spring 54 is compressed, and the adsorption guide bolt 52 extends upward in the opposite direction relative to the adsorption guide tube 51. In this process, the adsorption buffer spring 54 prevents the weight of the main body from rigidly pressing the suction cup 53, which is conducive to extending the life of the suction cup 53.

[0031] The longitudinal main pipe 1 is detachably mounted with a pump assembly mounting member 61. The pump assembly mounting member 61 in this embodiment is an angle steel integrally welded to the middle transverse pipe mounting sleeve 2, and is mounted on the longitudinal main pipe 1 together with the transverse pipe mounting sleeve 2. Two symmetrically arranged load-bearing angle steels 62 are fixedly welded to the pump assembly mounting member 61, and a vacuum pump assembly 6 is mounted on the load-bearing angle steels 62. The vacuum pump assembly 6 is small in size, and the load-bearing angle steels 62, i.e., the angle steels in the pump assembly mounting member 61, do not need to be of a large length, and are also conveniently made with angle steel scraps.

[0032] The pipeline between the air inlet of the vacuum pump assembly 6 and each of the adsorption assemblies 5 is connected with an adsorption control valve 63. When the vacuum pump assembly 6 is in operation, its air inlet forms an air suction, and after the adsorption control valve 63 is opened, it extracts the gas at the suction cup 53; when the suction cup 53 is pressed against the surface of the small plate, this negative pressure air suction causes the suction cup 53 to produce an adsorption effect on the small plate. When the main body rises and moves, the small plate is moved. The adsorption control valve 63 can be implemented by a hand sliding valve or the like.

[0033] The longitudinal main pipe 1 is provided with two hanging and mounting sleeves 7, which are also short in length and convenient to be made with pipe scraps. The hanging and mounting sleeves 7 are provided with a hanging position positioning structure 71, which is also implemented with radial bolts and will not be described in detail here. The hanging and mounting sleeves 7 are respectively welded with hanging risers 72, and the tops of the hanging risers 72 are welded with hanging cross pipes 73, and the hanging cross pipes 73 are fixedly welded with hanging ears 74, so that the main body of this embodiment can be used in conjunction with other lifting mechanisms or equipment. The hanging risers 72 and the hanging cross pipes 73 constitute a connecting frame for the hanging ears 74, which are short in length and convenient to be made with pipe scraps. Moreover, since they do not need to be fitted with other pipe fittings, the cross-sectional size is less restricted, which is convenient for the use of pipe scraps different from the longitudinal main pipe 1, the cross pipe 3, etc.

[0034] Two handle mounting plates 8 are fixedly mounted on the longitudinal main pipe 1, and the fixed mounting here can be directly fixed by bolts. A handle extension pipe 81 extending laterally is welded on each of the handle mounting plates 8, and an operating handle 82 is fixedly welded on the ends of the two handle extension pipes 81. By setting the operating handle 82, it is convenient for manual control of the deflection direction of the main body during the moving process, and it is convenient to cooperate with the moving to place the small panel in the required posture to the specified position. The handle extension pipe 81 is not long, which is convenient for production with pipe waste, and there is no need for set matching, which is also convenient for flexible selection of other pipe waste for production.

[0035] A valve mounting tube 83 is fixedly welded between the two handle extension tubes 81, and the adsorption control valve 63 is mounted on the valve mounting tube 83. The valve mounting tube 83 is also conveniently and flexibly made of various pipe material residues, and it is close to the operating handle 82, which is convenient for manual control of adsorption.

[0036] The main body of this embodiment is mainly made of square tubes, and each component structure is formed into a shorter size by means of plug-in and set-fitting, so that it is convenient to use the pipe surplus material for manufacturing, which is conducive to optimizing production cost control. The set connection allows the longitudinal and lateral positions of each adsorption component 5 to be flexibly adjusted, so that it can be adapted to small panels of various sizes for use. The load capacity of this embodiment can reach 300kg, which can meet the needs of moving small panels.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
