Description

Technical Field

[0001] The utility model belongs to the technical field of drum conveying equipment and relates to a conveying line device. Background Technique

[0002] On an automated production line, a conveying roller track line composed of drums is used. The conveying roller track line is generally driven by an independent reduction motor. A sprocket on the output shaft of the reduction motor drives the driven rollers on the track to rotate, so as to convey workpieces or materials to the target position. During operation, according to the requirements of the production process, a single workpiece or material needs to stay briefly at a certain position. At this time, generally the motor is stopped and the whole line stops running. If the rollers are not allowed to stop rotating, the surface of the workpiece will be worn due to friction with the rollers.

[0003] To solve the above technical problems, the patent document with the application number 202220723806.3 provides an accumulative drum conveying line, which includes a driver, a first roller guide rail and a second roller guide rail. The first roller guide rail includes a first linkage shaft, a plurality of first roller groups and a plurality of first bearing members. The first linkage shaft is provided with a plurality of first linkage gears. The first roller group includes a first roller body and a first bevel gear. The first roller body is used for conveying materials. The first roller body and the first bevel gear are connected. The first bevel gear is meshed with the first linkage gear. When the first roller body is subjected to a limiting force, the first linkage shaft rotates idly.

[0004] The above accumulative drum conveying line can automatically accumulate materials without stopping the machine. However, in order to adapt to different occasions, those skilled in the art hope to propose more accumulative drum devices with different structures. Summary of the Invention

[0005] In view of the above problems existing in the prior art, the utility model provides an accumulative drum. The technical problem to be solved by the utility model is: how to make a single workpiece stay briefly without stopping the motor.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] An accumulative drum includes a first cylinder. A first support seat and a second support seat are arranged inside the first cylinder. A first core shaft that can rotate relative to the first support seat and the second support seat is arranged on the first support seat and the second support seat. A friction plate and a rotatable driven sprocket are sleeved on one end of the first core shaft. The friction plate and the driven sprocket are located outside the first support seat. An extrusion member one for extruding the second support seat and elastically pressing the friction plate and the driven sprocket by the first support seat is arranged on the other end of the first core shaft.

[0008] Its working principle is:

[0009] The mandrel 1 is fixed on the aluminum profiles on both sides of the raceway, and the fixing method is different. The friction plate is arranged between the support base 1 and the driven sprocket. The extrusion part 1 presses the support base 2 on the cylinder 1, causing the support base 1 and the support base 2 to axially move to the right. After that, the support base 1 contacts the friction plate, and the friction plate contacts the driven sprocket. Under the action of the extrusion part 1, the support base 1 elastically compresses the friction plate and the driven sprocket. When the driven sprocket rotates, it drives the cylinder 1 to rotate through the friction plate; when the workpiece on the cylinder 1 is blocked and stops running, the driven sprocket and the friction plate slip, the driven sprocket still rotates, but the cylinder 1 stops rotating, making the workpiece and the cylinder 1 relatively stationary.

[0010] In this kind of accumulation roller, without the motor stopping, a single workpiece can stay briefly under the action of the stopper, without affecting the continuous operation of other workpieces. Moreover, the stationary workpiece will not cause friction to the cylinder 1, avoiding damage to the cylinder 1.

[0011] The so-called accumulation roller drives the workpiece to run by the friction between the driven sprocket and the cylinder 1. When the friction between the blocked workpiece and the surface of the cylinder 1 is greater than the friction between the driven sprocket and the cylinder 1, the driven sprocket and the cylinder 1 will slip, the driven sprocket continues to rotate while the cylinder 1 and the workpiece remain stationary.

[0012] In the above-mentioned accumulation roller, the extrusion part 1 includes an adjusting nut and a spring. The adjusting nut is threadedly connected to one end of the mandrel 1, and the spring is located between the adjusting nut and the support base 2 and is in a compressed state.

[0013] The spring is in a compressed state. Under the elastic force of the spring, the support base 1 elastically compresses the friction plate and the driven sprocket.

[0014] In the above-mentioned accumulation roller, the support base 1 is bearing 1, and the support base 2 is bearing 2.

[0015] Setting bearing 1 and bearing 2 can well improve the stability when the cylinder 1 rotates.

[0016] As an embodiment, bearing 1 and bearing 2 are rolling bearings.

[0017] In the above-mentioned accumulation roller, a rubber layer is provided on the cylinder 1.

[0018] The rubber layer can increase the friction between the workpiece and the cylinder 1, enabling the roller to better convey the workpiece.

[0019] In the above-mentioned accumulation roller, a bearing 3 is installed on the end of the mandrel 1, and the driven sprocket is installed on the bearing 3.

[0020] The provision of Bearing III can ensure the stability of the driven sprocket during rotation.

[0021] The present utility model also provides a conveyor line device, which includes a frame and a driving roller. The driving roller includes a cylinder body II, within which a support base I and a support base II are provided. A mandrel II that can rotate relative to the support base I and the support base II is arranged on the support base I and the support base II. A friction plate and a driving sprocket are sleeved on one end of the mandrel II. The friction plate and the driving sprocket are located outside the support base I. An extrusion member II is arranged on the other end of the mandrel II for extruding the support base II and enabling the support base I to elastically compress the friction plate and the driving sprocket. A motor is arranged on the frame, and the output shaft of the motor is connected to the mandrel II. A number of the above-mentioned accumulation rollers are also arranged on the frame. A chain is connected between the driving sprocket on the driving roller and the driven sprocket of an adjacent accumulation roller, and a chain is connected between the driven sprockets of adjacent accumulation rollers.

[0022] The motor can be a reduction motor. The mandrel II is rotatably installed on the aluminum profiles on both sides of the raceway through a self-aligning bearing seat. The motor drives the mandrel II to rotate, and the driving sprocket rotates with the mandrel II. The friction plate is arranged between the support base I and the driving sprocket. The extrusion member II presses and pushes the support base II on the cylinder body II, causing the support base I and the support base II to axially move in the right direction. Then, the support base I comes into contact with the friction plate, and the friction plate comes into contact with the driving sprocket. Under the action of the extrusion member II, the support base I elastically compresses the friction plate and the driving sprocket. When the driving sprocket rotates, it drives the cylinder body II to rotate through the friction plate; when the workpiece on the cylinder body II is blocked and stops running, the driving sprocket and the friction plate slip, the driving sprocket still rotates, but the cylinder body II stops rotating, making the workpiece and the cylinder body II relatively stationary;

[0023] The driving sprocket drives the driven sprocket of an adjacent accumulation roller to rotate through a chain, and the driven sprocket drives the driven sprockets of other accumulation rollers to rotate through a chain. Under the action of the extrusion member I, the support base I elastically compresses the friction plate and the driven sprocket. When the driven sprocket rotates, it drives the cylinder body I to rotate through the friction plate; when the workpiece on the cylinder body I is blocked and stops running, the driven sprocket and the friction plate slip, the driven sprocket still rotates, but the cylinder body I stops rotating, making the workpiece and the cylinder body I relatively stationary.

[0024] In the above-mentioned conveyor line device, the extrusion member II includes an adjusting nut and a spring. The adjusting nut is threadedly connected to one end of the mandrel II, and the spring is located between the adjusting nut and the support base II and is in a compressed state.

[0025] The spring is in a compressed state. Under the elastic force of the spring, the support base I elastically compresses the friction plate and the driving sprocket.

[0026] In the above-mentioned conveyor line device, the first support seat is the first bearing, and the second support seat is the second bearing.

[0027] The setting of the first bearing and the second bearing can well improve the stability of the second mandrel during rotation and better perform transmission.

[0028] As an embodiment, the first bearing and the second bearing are rolling bearings.

[0029] Compared with the prior art, the advantages of the present utility model are as follows:

[0030] In the case where the motor of this accumulation roller does not stop rotating, a single workpiece can stay briefly under the action of the stopper, and at the same time, it does not affect the continuous operation of other workpieces, and the staying workpiece will not cause friction to the first cylinder, avoiding damage to the first cylinder.
