Description

Technical Field

[0001] The utility model relates to the technical field of roller conveyor lines, in particular to an accumulation type roller conveyor line. Background Art

[0002] The accumulation roller conveyor line is a common material conveying system, usually used in automated warehousing and logistics systems to handle and transport large quantities of boxed goods, pallets or other materials. This conveyor line has an accumulation function, which can stack and accumulate materials during the conveying process so that they can be sorted, loaded or stored when needed.

[0003] For example, a stacking roller conveyor disclosed in the authorization announcement number CN204021701U includes a support frame, a drive shaft, a conveying roller, a drive belt, and a side plate. The beneficial effect of adopting the above technical solution is that the device can make boxes contact each other one by one and wait in line without stopping the machine, and when a certain number is reached, they are uniformly released to the main conveyor line, thereby greatly reducing the start and stop frequency of the branch conveyor line.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] Although the above patent allows boxes to be placed in contact with each other and queue up one by one without stopping the machine, the distance between each item cannot be adjusted when resuming the conveying of items. This makes it inconvenient for workers to separate and pick up items when manually handling them beside the conveyor line. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A stacking roller conveyor line comprises a frame 1, a plurality of driving rollers 2 are arranged side by side on one side of the frame 1, a first active roller 3 is arranged on the other side of the frame 1, and first driven rollers 4 are arranged on both sides of the frame 1 located on the first active roller 3; a transmission shell 5 is fixedly installed on the outside of one side of the frame 1, a shell 6 is arranged on the side of the transmission shell 5 close to the first active roller 3, a clamping mechanism 7 is arranged on the inner and outer sides of the shell 6, and the clamping mechanism 7 comprises a third motor 701, a movable frame 702 and a clamping rod 703, a third motor 701 is fixedly installed on the top of the shell 6, a threaded rod 8 is fixedly installed on the output shaft of the third motor 701, and both ends of the threaded rod 8 are externally threadedly connected Connected to the movable frame 702, a pair of clamping rods 703 are arranged on both sides of the ends of the two movable frames 702 close to the first active roller 3, and the threads on the two ends of the threaded rod 8 are in opposite directions; a second motor 9 is fixedly installed on the outside of the side of the frame 1 away from the shell 6, and the output shaft of the second motor 9 is fixedly connected to the first active roller 3, and a first single-groove pulley 10 is fixedly installed on the end of the first active roller 3 away from the second motor 9, and a second single-groove pulley 11 is arranged on the ends of the two first driven rollers 4 close to the first single-groove pulley 10, and the first single-groove pulley 10 is movably connected to the second single-groove pulleys 11 on both sides through a toothed belt 12, and the clamping rods 703 at both ends of the movable frame 702 are clamped on the inner and outer sides of the toothed belt 12;

[0027] In this embodiment, during operation, the driving roller 2 is used to control the movement of the article on it. When it is no longer necessary to control the movement of the article from the position of the first active roller 3 to the driving roller 2, the third motor 701 is started. After the third motor 701 is started, it drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, the movable frames 702 at both ends move toward each other. When the two movable frames 702 move toward each other, the toothed belt 12 is opened by the clamping rod 703, so that the toothed belt 12 is withdrawn from the outer side of the second single-groove pulley 11, so that the first driven rollers 4 at both ends will stop rolling. When it is necessary to control the movement of the article again, the movable frames 702 are controlled to move in opposite directions. The moving frame 702 moves in the same direction, so that the clamping rod 703 clamps the toothed belt 12 on the outside of the second single-groove pulley 11 in the opposite direction, so that the first active roller 3 can drive the second single-groove pulley 11 again and drive the first driven rollers 4 at both ends through the toothed belt 12. When the first object is sent to the driving roller 2, the first driven roller 4 is controlled to stop again until the object on the driving roller 2 moves to the specified position and then the first driven roller 4 is controlled to start. The reciprocating movement can adjust the distance between the objects without stopping the machine, so that when workers take the objects, it will not be inconvenient because the objects are too close.

[0028] Furthermore, since the toothed belt 12 is clamped on the outside of the second single-groove pulley 11 by the clamping rod 703, the wrap angle between the toothed belt 12 and the second single-groove pulley 11 is increased, which can improve the torque transmission capacity.

[0029] like Figure 4 As shown, a bracket 15 is fixedly installed on one side of the top movable frame 702, and a fixing bar 16 is fixedly installed on the top of the bracket 15;

[0030] In this embodiment, when the clamping rod 703 at the top opens the toothed belt 12, the rising of the clamping rod 703 will control the bracket 15 to rise synchronously, thereby blocking one side of the object. When the clamping rod 703 is reset, the bracket 15 will fall synchronously, thereby preventing the object from being driven onto the roller 2 by the first active roller 3, thereby achieving the purpose of preventing displacement.

[0031] like Figure 2 As shown, a first motor 13 is symmetrically arranged on the other side of the frame 1 close to the second motor 9, and a double-groove pulley 14 is fixedly installed on one end of the plurality of driving rollers 2 away from the first motor 13, and the plurality of double-groove pulleys 14 are movably connected by belts, and the number of the double-groove pulleys 14 is one more than the number of belts;

[0032] In this embodiment, when the object moves onto the driving roller 2, the first motor 13 is started. After the first motor 13 is started, it controls a driving roller 2 at its end to rotate. Because the other ends of several driving rollers 2 are connected through a double-groove pulley 14 and a belt transmission, and the double-groove pulley 14 is a double-groove structure, through several belt staggered transmissions, all the driving rollers 2 can move synchronously in the same direction.

[0033] Working principle: During operation, the driving roller 2 is used to control the movement of the items on it. When it is not necessary to control the movement of the items from the position of the first active roller 3 to the driving roller 2 again, the third motor 701 is started. After the third motor 701 is started, it drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, the movable frames 702 at both ends move toward each other. When the two movable frames 702 move toward each other, the clamping rod 703 is used to open the toothed belt 12, so that the toothed belt 12 is withdrawn from the outer side of the second single-groove pulley 11, so that the first driven rollers 4 at both ends will stop rolling. When it is necessary to control the movement of the items again, the movable frames 702 are controlled to move in the same direction, so that the clamping rod 703 clamps the toothed belt 12 in the opposite direction to the outside of the second single-groove pulley 11, so that the first active roller 3 can drive the second single-groove pulley 11 again and drive the first driven rollers 4 at both ends through the toothed belt 12. When the first item is sent to the driving roller 2, the first driven roller 4 is controlled to stop again until the item on the driving roller 2 moves to the specified position and then the first driven roller 4 is controlled to start. The reciprocating movement can adjust the spacing of the items without stopping the machine.

[0034] 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 preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
