Description

Technical Field

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

[0002] Existing linear conveying systems, such as augers, gear racks, walking beams, etc., can directly convey materials along a straight line for a distance, 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 materials and then convey them. After the materials are in place, they need to be separated from the carrier and the carrier is reset, which leads to the existing circulating drive mechanisms, such as synchronous belts, etc. However, due to the transmission characteristics of the synchronous belts themselves, 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. 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, and the efficiency is low.

[0003] To solve the above problems, there is a technology that combines a circulating track with a linear conveyor. For example, the patent application number 201910456561.5 for "Equipment for controlling the movement of an independent mover along a certain path" uses a gear rack to convey the carrier and a synchronous belt to convey the carrier at the turning position to solve the problems of accuracy and efficiency. However, it uses a synchronous belt for conveying, and the transition between the gear and the synchronous belt may cause problems such as tooth jumping, and the structure is complicated. Summary of the invention

[0004] The purpose of the invention 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 in transition.

[0005] The present invention 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 of the processing station to the output end; the magnetic traction mechanism is used to drive the mounting block from the output end of the processing station to the input end.

[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 driving 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 of the circulating conveying device is also simpler. A further technical solution of the present invention is: at least one straight section is provided on the circulating guide rail, the processing station is arranged along the straight section, and the driving 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 multiple mounting blocks need to be positioned, the driving mechanism repeatedly moves between the processing stations, and the mounting blocks are positioned in sequence according to the corresponding positions on the driving 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 suspension.

[0008] A further technical solution of the present invention is that the magnetic traction mechanism has the same shape as the circulating guide rail portion from the output end to the input end of the processing station. Thus, the magnetic traction mechanism can drive the installation block from the output end of the processing station back to the input end, and cooperate with the driving mechanism to move the installation block from the input end to the output end of the processing station, thereby realizing the cyclic transportation of the installation block.

[0009] A further technical solution of the present invention is: the circulating guide rail comprises a first straight segment, a second straight segment and an arc segment for connecting the end of the first straight segment and the end of the second straight segment, the driving mechanism is placed in the first straight segment, and the magnetic traction mechanism is arranged close to the second straight segment. The circulating guide rail is a circulating structure, the driving mechanism completes the conveyance of the mounting block on the first straight segment, the magnetic traction mechanism is arranged close to the second straight segment, and can drive the mounting block to move in the second straight segment, and the mounting block of the arc segment can be squeezed and pushed by the mounting block below.

[0010] A further technical solution of the present invention is: the magnetic traction mechanism includes a circulating conveyor belt and a magnet disposed on the circulating conveyor belt. The magnet cooperates with the mounting block, and can drive the mounting block to move in the area where the magnet is close to the mounting block; the magnet is on the magnetic traction mechanism, and can realize continuous movement of the magnet, while the driving mechanism moves intermittently, the mounting block on the processing station is not affected by other mounting blocks, and the mounting blocks from the output end to the input end of the processing station are continuously transported, and the number of mounting blocks is required to be 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 arranged in the circulating guide rail. The elliptical circulating guide rail is more suitable for the positioning requirements of the pre-filled package in the present invention, and the magnetic traction mechanism is placed in the circulating guide rail to facilitate the movement of the mounting block along the circulating guide rail.

[0012] Beneficial effects of the present invention: 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 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

[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 by magnetic connection. 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 driving 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 of 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 driving mechanism 3 is arranged on one side of the straight section of the circulating guide rail 1 and can transport the mounting block 2 along a straight line.

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

[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 arc segment 15 for connecting the end of the first straight segment 13 and the end of the second straight segment 14. The driving mechanism 3 is disposed in the first straight segment 13, and the magnetic traction mechanism 4 is disposed near the second straight segment 14. The circulating guide rail is a circulating structure, the driving mechanism completes the conveyance of the mounting block on the first straight segment, the magnetic traction mechanism is disposed near the second straight segment, and can drive the mounting block to move in the second straight segment, and the mounting block of the arc segment can be squeezed and pushed by the mounting block below.

[0036] In this embodiment, the magnetic traction mechanism 4 includes a circulating conveyor belt and a magnet 41 arranged on the circulating conveyor belt. The magnet cooperates with the mounting block, and can drive the mounting block to move in the area where the magnet is close to the mounting block; the magnet is on the magnetic traction mechanism, which can realize the continuous action of the magnet, while the driving mechanism moves intermittently, the mounting block on the processing station is not affected by other mounting blocks, and the mounting blocks from the output end to the input end of the processing station are continuously transported, and the number of mounting blocks is required to be small and there is no spacing requirement.

[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 in the circulating guide rail 1. The elliptical circulating guide rail is more suitable for the positioning requirements of the pre-filled in the present invention, and the magnetic traction mechanism is placed in 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.
