Description

Technical Field

[0001] The utility model relates to the technical field related to industrial production and transportation, and more precisely to a turning conveying device. Background Art

[0002] In the process of industrial production and processing, it is often necessary to transfer workpieces from the previous process device to the next process device. In this process, the workpieces need to be transported by conveying devices. Most existing conveying devices are in the form of linear conveying, which is relatively mature. However, the use of linear conveying devices requires that the process devices be arranged in sequence according to the process sequence. For production lines that require multi-process processing, the process devices arranged in sequence result in the production line length being too long, which is more demanding on the production site and is not conducive to production arrangement preparation.

[0003] In order to reduce the length of the production line, one way is to combine different process devices together and reduce the length of the production line by reducing the number of process devices. This method is difficult to design, and the combined process devices have disadvantages such as complex structure and difficult maintenance. Another way is to improve the conveying device, such as designing a curved conveying device so that adjacent process devices can be staggered to reduce the length of the production line. However, how to ensure the stable conveying of the workpiece in the curved section of the curved conveying device is a major problem. The conveying chain plate is prone to misalignment and jamming in the curved section of the conveying device.

[0004] In addition, the existing conveyor chain plates and brackets are in sliding contact, which generates sliding friction during operation and causes greater resistance. The resistance is even greater when conveying workpieces with heavier mass, resulting in low operating efficiency of the conveying device, and is not suitable for transporting large mass workpieces.

[0005] In summary, the art needs to design a conveying device that can turn and operate stably, which is arranged between adjacent process devices to transfer workpieces so as to shorten the overall length of the production line. Utility Model Content

[0026] 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.

[0027] like Figure 1 and Figure 2 As shown, the present application provides a turning conveying device including a frame 1, a plurality of chain plates 2 connected end to end, and a driving assembly 3. The frame 1 includes straight sections 10 at both ends and a turning section 11 connecting the two straight sections 10. The plurality of chain plates 2 are arranged on the frame 1 in a chain-like manner, and the plurality of chain plates 2 are connected to the driving assembly 3. The driving assembly 3 drives the chain plates 2 to move along the frame 1. The upper end of the frame 1 has a platform 100 for supporting the chain plates 2, the bottom of the chain plates 2 has a roller assembly 21 rollingly connected to the platform 100, the side of the turning section 11 has a turning guide rail 112, and the side of the chain plates 2 has a turning roller 22 docking with the turning guide rail 112. Preferably, the turning guide rail 112 is arranged on the inner ring side of the turning section 11. By setting a rolling connection between the chain plate 2 and the platform 100, instead of the sliding connection method in the prior art, the friction between the chain plate 2 and the platform 100 can be reduced to transport workpieces with larger mass; by setting the chain plate 2 to dock with the turning guide rail 112 through the turning roller 22, the chain plate 2 can be guided during the turning process to make it turn smoothly and prevent the chain plate from being dislocated, stuck, etc.

[0028] For more information, see Figure 3 and Figure 4 The chain plate 2 includes a plate body 20, and the bottom of the plate body 20 has two roller assemblies 21 arranged symmetrically and in parallel. A turning roller 22 is provided on one side of the bottom of the plate body 20, and the side of the turning roller 22 protrudes from the side plane of the plate body 20. The bottom of the plate body 20 also has a connecting assembly 23, and the connecting assembly 23 includes a protruding connecting member 231 and a connecting seat 232 arranged in sequence. The protruding connecting member 231 of the chain plate 2 is hinged to the connecting seat 232 of the previous chain plate 2, and the protruding connecting member 231 of the next chain plate 2 is hinged to the connecting seat 232 of the chain plate 2. It is worth noting that after the protruding connecting member 231 is connected to the connecting seat 232, it has a certain tilting range of motion to meet the turning requirements.

[0029] The plate body 20 can be designed to be thicker than the plate body of the chain plate in the prior art. Due to the rolling connection method, the plate body 20 can support a heavier weight. The thicker plate body 20 has greater strength and is more suitable for supporting workpieces with heavier weight.

[0030] Furthermore, it is preferred that the width of the middle portion of the plate body 20 is greater than the width of the two ends, so as to reduce the mutual obstruction between the plate bodies 20 of adjacent chain plates 2 when turning, thereby ensuring the stability of the turn.

[0031] See also Figure 2 and Figure 5 The straight section 10 is combined with a plurality of straight tension rollers 101, and the chain plate 2 at the bottom is connected to the straight tension rollers 101. The straight tension rollers 101 squeeze the chain plate 2 of the straight section 10 and tension the surrounding chain plate 2. The turning section 11 is combined with a plurality of turning tension rollers 111, and the turning tension rollers 111 squeeze the chain plate 2 of the turning section 11 and tension the surrounding chain plate 2. Specifically, the diameter of the turning tension rollers 111 gradually increases from the inner ring of the turning section 11 to the outer ring of the turning section 11, so as to balance the centrifugal force when the workpiece is transported, and ensure the stability of the workpiece when it is turned.
