Description

Technical Field

[0001] The utility model relates to the technical field of circulating conveying guide rails, in particular to a circulating conveying device. Background Art

[0002] Existing linear conveying systems, such as augers, gear racks, and walking beams, can directly convey materials for a certain distance in a straight line, and their positioning accuracy is high. However, for some materials that cannot be directly transported, such as cartridge bottles, a carrier is usually required to fix the material and then convey it. After the material is in place, it needs to be separated from the carrier and the carrier is reset, which leads to the development of existing circulating drive mechanisms, such as synchronous belts. However, due to the transmission characteristics of the synchronous belt itself, the positioning accuracy is insufficient, and the bottle mouth diameter of the cartridge bottle is only a few millimeters. When the cartridge bottle is filled and plugged, the positioning accuracy of the synchronous belt is difficult to meet the requirements of the cartridge bottle. In order to improve the positioning accuracy of the synchronous belt, a steel belt structure is currently used. However, when the speed is fast, the carrier vibrates greatly at the bend of the synchronous belt, which can easily cause the steel belt to break. There is also a secondary positioning method. After the carrier is in place, the positioning mechanism acts to position the carrier. The conveying and positioning of the carrier cannot be carried out at the same time, which is inefficient.

[0003] To solve the above problems, there are technologies that combine circulating tracks with linear conveying. For example, the patent application number 201910456561.5 is "Equipment for controlling the movement of an independent mover along a certain path". It uses rack and pinion conveyors and uses synchronous belts for conveying at turning positions to solve the problems of accuracy and efficiency. However, it uses synchronous belts for conveying, and the transition between gears and synchronous belts may cause problems such as tooth jumping, and the structure is complicated. Utility Model Content

[0004] The purpose of the utility model is to provide a circulating conveying device, which solves the problems of tooth jumping and complex structure in the prior art when the gear and the synchronous belt are transitionally connected.

[0005] The utility model is implemented as follows: a circulating conveying device includes a circulating guide rail and a mounting block placed on the circulating guide rail, the circulating guide rail is provided with a driving mechanism and a magnetic traction mechanism that can drive the mounting block to slide, the driving mechanism is used to drive the mounting block from the input end to the output end of the processing station; the magnetic traction mechanism is used to drive the mounting block from the output end to the input end of the processing station.

[0006] In the present invention, after the mounting block is output from the output end of the processing station, the magnetic traction mechanism and the mounting block are matched in a magnetic connection manner. The matching method is simple and can be matched together without high-precision processing. Then the magnetic traction mechanism transports the mounting block from the output end of the processing station to the input end. During the movement, the mounting block can move continuously without affecting the intermittent action of other mounting blocks on the drive mechanism. The number of mounting blocks on the circulating guide rail is loose and there is no requirement for the spacing between the mounting blocks. The control system design for the circulating conveying device is also simpler. A further technical solution of the present invention is that at least one straight section is provided on the circulating guide rail, the processing station is arranged along the straight section, and the drive mechanism is arranged on one side of the straight section of the circulating guide rail and can transport the mounting block along a straight line. The mounting block is positioned in the straight section, which is convenient for operating the product transported on the mounting block; when there are multiple mounting blocks that need to be positioned, the drive mechanism repeatedly moves between the processing stations, and the mounting blocks are positioned in sequence according to the corresponding positions on the drive mechanism.

[0007] A further technical solution of the present invention is that the conveying mechanism is any one of a gear rack, a walking beam, an auger, and a magnetic levitation.

[0008] A further technical solution of the present invention is that the magnetic traction mechanism and the circulating guide rail portion from the output end to the input end of the processing station are of the same shape. Thus, the magnetic traction mechanism can drive the mounting block from the output end of the processing station back to the input end, and cooperate with the drive mechanism to move the mounting block from the input end to the output end of the processing station, thus realizing the circular conveyance of the mounting block.

[0009] A further technical solution of the present invention is as follows: the circulating guide rail comprises a first straight segment, a second straight segment, and an arcuate segment connecting the ends of the first and second straight segments. The drive mechanism is positioned in the first straight segment, and the magnetic traction mechanism is positioned adjacent to the second straight segment. The circulating guide rail has a circulating structure, with the drive mechanism transporting the mounting block on the first straight segment. The magnetic traction mechanism is positioned adjacent to the second straight segment, driving the mounting block in the second straight segment. The mounting block in the arcuate segment can be squeezed and pushed by the mounting block below.

[0010] A further technical solution of the present invention is that the magnetic traction mechanism includes an endless conveyor belt and a magnet mounted on the endless conveyor belt. The magnet cooperates with the mounting block to drive the mounting block in the area where the magnet is close to the mounting block. The magnet on the magnetic traction mechanism can achieve continuous movement of the magnet while the drive mechanism moves intermittently. The mounting block at the processing station is not affected by other mounting blocks, and the mounting blocks are continuously transported from the output end to the input end of the processing station. The number of mounting blocks required is small and there is no spacing requirement.

[0011] A further technical solution of the present invention is that the magnetic traction mechanism and the circulating guide rail are both elliptical, and the magnetic traction mechanism is disposed within the circulating guide rail. The elliptical circulating guide rail is more suitable for the positioning requirements of the pre-potting in the present invention, and the magnetic traction mechanism is disposed within the circulating guide rail to facilitate the movement of the mounting block along the circulating guide rail.

[0012] The beneficial effects of the present invention are as follows: in the present invention, after the mounting block is output from the output end of the processing station, the magnetic traction mechanism and the mounting block are matched in a magnetic connection manner. The matching manner is simple and can be matched together without the need for high-precision processing. Then the magnetic traction mechanism transports the mounting block from the output end of the processing station to the input end. During the movement, the mounting block can move continuously without affecting the intermittent action of other mounting blocks on the driving mechanism. The requirements for the number of mounting blocks on the circulating guide rail are loose and there is no requirement for the spacing between the mounting blocks. The control system design of the circulating conveying device is also simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1:

[0027] Figure 1-6 A circulating conveying device is shown, comprising a circulating guide rail 1 and a mounting block 2 placed on the circulating guide rail 1, characterized in that the circulating guide rail 1 is provided with a driving mechanism 3 and a magnetic traction mechanism 4 that can drive the mounting block 2 to slide, the driving mechanism 3 is used to drive the mounting block 2 from the input end to the output end of the processing station; the magnetic traction mechanism 4 is used to drive the mounting block 2 from the output end to the input end of the processing station.

[0028] In the present invention, after the mounting block is output from the output end of the processing station, the magnetic traction mechanism and the mounting block are matched in a magnetic connection manner. The matching method is simple and can be matched together without high-precision processing. Then the magnetic traction mechanism transports the mounting block from the output end of the processing station to the input end. During the movement, the mounting block can move continuously without affecting the intermittent action of other mounting blocks on the drive mechanism. The number of mounting blocks on the circulating guide rail is loose and there is no requirement for the spacing between the mounting blocks. The control system design for the circulating conveying device is also simpler. In this embodiment, at least one straight section is provided on the circulating guide rail 1, and the processing station is arranged along the straight section. The drive mechanism 3 is provided on one side of the straight section of the circulating guide rail 1 and can transport the mounting block 2 along a straight line. The mounting block is positioned in the straight section, which is convenient for operating the product transported on the mounting block; when there are multiple mounting blocks that need to be positioned, the drive mechanism repeatedly moves between the processing stations, and the mounting blocks are positioned in sequence according to the corresponding positions on the drive mechanism.

[0029] In this embodiment, the mounting block is used to mount a carrier, materials, a bottle, etc.

[0030] In this embodiment, the conveying mechanism 3 is a walking beam. Specifically, the conveying track of the driving mechanism 3 is a parallelogram. The driving mechanism moves between the processing stations, so that the mounting block is transported and positioned along the circulating guide rail at the same time; in the case of multiple mounting blocks, the mounting block can be driven to move and the mounting block can be positioned in turn at the corresponding position on the driving mechanism; the driving mechanism 3 is connected to the driving assembly 6 through the connecting rod mechanism 5. The driving assembly drives the connecting rod mechanism to move, so that the conveying track of the driving mechanism connected to the connecting rod mechanism is a parallelogram; the driving assembly includes a first driving motor and a second driving motor, and the first driving motor and the second driving motor are both connected to the driving assembly; the driving mechanism 3 is provided with at least one positioning part 31 that can cooperate with the mounting block 2. After the driving mechanism cooperates with the mounting block through the positioning part at the input end of the processing station, the driving mechanism drives the mounting block to move synchronously to the set position. The driving mechanism not only drives the mounting block to move but also positions the mounting block. Compared with the prior art solution, the present utility model is more efficient and more accurate; the positioning part on the driving mechanism is a groove, and the mounting block is provided with a positioning member 21 that cooperates with the groove. Mounting block

[0031] As another embodiment, the conveying mechanism is any one of a rack and pinion, an auger, and magnetic levitation.

[0032] In this embodiment, the arrangement direction of the positioning portions is linear, consistent with the shape of the circulating guide rail between the input end and the output end of the processing station.

[0033] In this embodiment, the magnetic traction mechanism 4 is partially identical in shape to the circulating guide rail 1. Thus, the magnetic traction mechanism can drive the mounting block from the output end of the processing station back to the input end, and cooperate with the driving mechanism to realize the cyclic transportation of the mounting block.

[0034] In this embodiment, the shape of the circulating track portion between the output end and the input end of the processing station includes a straight line segment and arc segments at both ends of the straight line segment.

[0035] In this embodiment, the circulating guide rail 1 includes a first straight segment 13, a second straight segment 14, and an arcuate segment 15 connecting the ends of the first straight segment 13 and the second straight segment 14. The drive mechanism 3 is located in the first straight segment 13, and the magnetic traction mechanism 4 is located near the second straight segment 14. The circulating guide rail has a circulating structure. The drive mechanism transports the mounting block on the first straight segment, and the magnetic traction mechanism is located near the second straight segment to drive the mounting block in the second straight segment. The mounting block in the arcuate segment can be squeezed and pushed by the mounting block below.

[0036] In this embodiment, the magnetic traction mechanism 4 includes an endless conveyor belt and magnets 41 mounted on the endless conveyor belt. The magnets cooperate with the mounting blocks, driving the mounting blocks in the area where the magnets are close to the mounting blocks. The magnets on the magnetic traction mechanism enable continuous movement of the magnets while the drive mechanism moves intermittently. The mounting blocks at the processing stations are not affected by other mounting blocks, and the mounting blocks are continuously transported from the output end to the input end of the processing station. This requires a small number of mounting blocks and no spacing requirements.

[0037] In this embodiment, a magnet 22 is provided on the mounting block 2 and is magnetically connected to the magnet 41 on the magnetic traction mechanism 4 .

[0038] In this embodiment, the magnetic traction mechanism 4 and the circulating guide rail 1 are both elliptical, and the magnetic traction mechanism 4 is arranged inside the circulating guide rail 1. The elliptical circulating guide rail is more suitable for the positioning requirements of the pre-potting in the utility model, and the magnetic traction mechanism is placed inside the circulating guide rail to facilitate the movement of the mounting block along the circulating guide rail.

[0039] In this embodiment, the circulating guide rail is a runway type.

[0040] In this embodiment, the driving mechanism operates intermittently, while the magnetic traction mechanism operates continuously, so that the mounting block can be quickly recycled without affecting the operation of the driving mechanism on the mounting block.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
