Description

Technical Field

[0001] This utility model relates to the field of transport machinery technology, specifically a roller conveyor with variable direction conveying capability. Background Technology

[0002] Roller conveyors, as a common material conveying equipment, are mainly composed of a frame, rollers, and other structures.

[0003] In processes such as laser engraving and visual inspection of sheet metal, roller conveyors need to be able to change the conveying direction to transport sheets of different grades to their corresponding storage areas for easy sorting and processing. Therefore, existing roller conveyors are equipped with a manual or electric rotating platform on their underside. After processing or inspection, the conveying direction of the roller conveyor is changed, and the sheet metal is manually pushed out to the corresponding storage area. The change of conveying direction is achieved by rotation. To ensure that the sheet metal can be placed stably, the speed of rotating the roller conveyor is relatively slow. After completion, it needs to be reset before it can be used again, which cannot match the production schedule well.

[0004] Therefore, in order to solve the above problems, a roller conveyor with variable direction is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a roller conveyor with variable direction, which directly changes the conveying direction of the plate by changing the force applied to the plate, resulting in higher working efficiency and thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reversible conveying roller conveyor, comprising a base plate, four roller tables fixedly mounted on the upper side of the base plate via support columns, the four roller tables being arranged in a rectangular array; each roller table comprising a U-shaped seat, a roller shaft, and rollers, the roller shaft being uniformly rotatably mounted inside the U-shaped seat, and several sets of rollers being rotatably mounted on the circumferential side of the roller shaft via a rotating seat; a transmission assembly for connecting the roller shaft is mounted on the front side of the U-shaped seat, and a reduction motor is fixedly mounted on the rear side of the U-shaped seat, the output end of the reduction motor penetrating the side wall of the U-shaped seat and connected to one of the roller shafts.

[0007] Specifically, the distance between the inner rollers of each U-shaped seat shall not exceed 20 cm, and the distance between several sets of rollers on each roller shall not exceed 15 cm.

[0008] Specifically, each group of rollers consists of at least six rollers arranged in a circumferential pattern.

[0009] Specifically, the included angle between the roller axis and the roller shaft axis is ∠a, and the range of ∠a is 45° to 60°.

[0010] Specifically, the rollers in the left and right roller tables are symmetrically arranged, and the rollers in the front and rear roller tables are also symmetrically arranged.

[0011] Specifically, the circumferential side of the roller is an arc-shaped circumferential surface that protrudes outward from the middle.

[0012] Specifically, the transmission assembly includes a synchronous belt and a double-groove synchronous pulley. The same end of the roller extends out of the U-shaped seat and is fixedly mounted with a double-groove synchronous pulley. Adjacent double-groove synchronous pulleys are connected by a synchronous belt, and adjacent synchronous belts are installed in a staggered manner.

[0013] Furthermore, protective covers are fixedly installed on both the front and rear sides of the U-shaped seat, and the geared motor and transmission components are located inside the protective covers on the same side.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The rollers and wheels driven by the geared motor and transmission components can apply forces in different directions to the sheet metal. The four roller tables can integrate the forces to give the sheet metal direct directional movement, making the conveying faster and eliminating the need for the traditional methods of rotating, pushing, and resetting the sheet metal, thus enabling faster production.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figure 1 This utility model provides a variable-direction conveying roller conveyor, including a base plate 1. The base plate 1 is a rectangular plate structure with countersunk holes. In use, it is fixed at the work station with screws as an installation base. Four roller tables are fixedly installed on the upper side of the base plate 1 by support columns. The four roller tables are distributed in a rectangular array and support and transport the plate together.

[0019] Each roller table includes a U-shaped seat 2, a roller shaft 4, and rollers 3. The U-shaped seat 2 is a support component that is integrally stamped from a steel plate and bent upward at both ends. The roller shaft 4 is uniformly mounted inside the U-shaped seat 2 through bearings. Several sets of rollers 3 are rotatably mounted on the circumference of the roller shaft 4 through a rotating seat. When the roller shaft 4 rotates, it can drive the rollers 3 to rotate circumferentially, and the rollers 3 will rotate with the placed plate due to friction.

[0020] A transmission assembly 5 for connecting roller shafts 4 is installed on the front side of the U-shaped seat 2, and a geared motor 7 is fixedly installed on the rear side of the U-shaped seat 2. The output end of the geared motor 7 passes through the side wall of the U-shaped seat 2 and is connected to one of the roller shafts 4. The geared motor 7 can provide rotational power to one of the roller shafts 4, while the transmission assembly 5 is used to connect all the roller shafts 4 in the same U-shaped seat 2, so that the roller shafts 4 in each roller table have the same speed and direction of rotation.

[0021] For details, please refer to Figure 3 The distance between the inner roller shafts 4 of each U-shaped seat 2 shall not exceed 20 cm, and the distance between several sets of rollers 3 on each roller shaft 4 shall not exceed 15 cm; so as to ensure that several sets of rollers 3 can be distributed in a rectangular array and provide uniform support for the placed plate.

[0022] Please see Figure 2 Each set of rollers 3 consists of at least 6 rollers arranged in a circular pattern to ensure that the rollers 3 can support the board material more smoothly in sequence when the roller shaft 4 rotates.

[0023] Please see Figure 3 The included angle between the axis of roller 3 and the axis of roller 4 is ∠a, and the range of ∠a is 45° to 60°. This angle setting is more conducive to the interaction of frictional forces between the plate and roller 3.

[0024] The rollers 3 on the left and right sides of the roller table are symmetrically arranged, and the rollers 3 on the front and rear sides of the roller table are also symmetrically arranged, so that the rollers 3 in adjacent roller tables (i.e., the two on the front side, the two on the back side, the two on the left side, or the two on the right side) can be distributed in a figure-eight shape.

[0025] In addition, the circumferential side of roller 3 is an arc-shaped circumferential surface that protrudes outward from the middle, and roller 3 is made of rubber material, which ensures that reliable friction can be generated between roller 3 and the plate, thereby ensuring the generation of mutual force.

[0026] Please see Figure 4 The transmission assembly 5 includes a synchronous belt 51 and a double-groove synchronous pulley 52. ​​The same end of the roller shaft 4 extends out of the U-shaped seat 2 and is fixedly mounted with a double-groove synchronous pulley 52. ​​Adjacent double-groove synchronous pulleys 52 are connected by a synchronous belt 51, and adjacent synchronous belts 51 are installed in a staggered manner. When one of the roller shafts 4 is driven, the double-groove synchronous pulleys 52 on the same roller shaft 4 are also driven. After being driven by the synchronous belt 51, they can rotate synchronously with other double-groove synchronous pulleys 52, thereby achieving the purpose of synchronously rotating the roller shaft 4.

[0027] Protective covers 6 are fixedly installed on both the front and rear sides of the U-shaped base 2. The geared motor 7 and the transmission assembly 5 are located inside the protective cover 6 on the same side. The protective cover 6 is used to protect the geared motor 7 and the transmission assembly 5 inside, to prevent foreign objects from entering and interfering with normal transmission, and to prevent operators from accidentally touching them, thus ensuring operational safety.

[0028] The geared motor 7 is electrically connected to an external industrial host, which controls the forward and reverse rotation of the geared motor 7. The industrial host can also perform human-machine interaction through its control panel.

[0029] The working principle of this embodiment: Please see Figure 5 Method 1, conveying the board forward: that is, the roller shaft 4 on the left rear roller table and the right front roller table rotates clockwise, while the roller shaft 4 on the right rear roller table and the left front roller table rotates counterclockwise. This allows the lateral (left-right direction) forces acting on the board by the rollers 3 in the left and right roller tables to cancel each other out, while the longitudinal (front-back direction) forces in the same direction can convey the board forward.

[0030] Method 2, conveying the board backward: The rotation direction of the roller shaft 4 in each roller table is opposite to that in Method 1. This allows the lateral forces acting on the board by the rollers 3 in the left and right roller tables to cancel each other out, while the longitudinal forces in the same direction can convey the board backward.

[0031] Please see Figure 6Method 3, conveying the plate to the right: All roller tables rotate clockwise, so that the longitudinal forces of the rollers 3 in the front and rear roller tables acting on the plate can cancel each other out, while the lateral forces in the same direction can convey the plate to the right.

[0032] Method 4, conveying the plate to the left: All roller tables rotate counterclockwise, so that the longitudinal forces of the rollers 3 in the front and rear roller tables acting on the plate can cancel each other out, while the lateral forces in the same direction can convey the plate to the left.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. 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 embodiments that can be understood by those skilled in the art.
