[0030] The embodiments of the utility model are only used for explaining the utility model, and are not used for limiting the scope of the utility model. In the following paragraphs, the utility model is described in a more specific manner with reference to the drawings. It should be noted that the drawings are in a very simplified form and all use non-precise proportions, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the utility model.
[0031] In the related art, the conveyor further comprises guide strips for guiding the chain, the guide strips have upper long grooves, and the chain is inserted into the upper long grooves of the two guide strips in the width direction. The guide strips are usually installed on the support through buckles, however, during the linear movement of the chain, the chain drives the guide strips to move, and when the guide strips move to the sprocket position, the guide strips are wound into the sprocket, thereby causing the conveyor to stop. For example, the guide strips have bottom long grooves, the buckles are buckled on the bottom long grooves, and the support is provided with clamping grooves for cooperating with the buckles, and the guide strips are limited in the width direction and the height direction of the guide strips through the cooperation of the buckles and the clamping grooves. When the friction between the chain and the upper long groove is greater than the friction between the buckle and the bottom long groove, the guide strips slowly move along the direction of movement of the chain, and when the guide strips move to the sprocket position, the guide strips are wound into the sprocket, thereby causing the conveyor to fail to work normally.
[0032] To solve the above problems, the chain guide assembly and the conveying device are provided.
[0033] In a first aspect, with reference to Figures 1 to 4 The chain guide assembly provided by the embodiment of the present application comprises a guide strip 1 and a limiting piece 2, the guide strip 1 comprises a guide main body 11, the guide main body 11 is formed with a guide groove 12, the guide groove 12 is used for cooperating with a chain 3, the limiting piece 2 is located at least on one side of the guide strip 1 along the direction of movement of the chain 3, the limiting piece 2 comprises a limiting plate 21, the limiting plate 21 has a limiting section 211 close to the guide strip 1, along the length direction of the guide strip 1, the orthogonal projection of the limiting section 211 overlaps the orthogonal projection of the guide main body 11, and the orthogonal projection of the limiting section 211 and the orthogonal projection of the guide groove 12 are staggered.
[0034] The chain guide assembly is applied to a conveying device, and the conveying device can be an accumulatingsystem pallet conveyor (APC). The number of the guide strips 1 is usually two, the chain 3 is located in the guide grooves 12 in the two guide strips 1 in the width direction of the chain 3, and the guide strips 1 are used for guiding and limiting the chain 3.

[0035] The direction of movement of the chain 3 can refer to Figure 1The direction of the arrow A is shown. The limiting piece 2 is preferably located on one side of the guide strip 1 along the running direction of the chain 3. The number of the limiting piece 2 is preferably equal to the number of the guide strip 1. The orthogonal projection of the limiting segment 211 and the orthogonal projection of the guide groove 12 are offset from each other, which means that the orthogonal projection of the limiting segment 211 and the orthogonal projection of the guide groove 12 do not overlap.

When the distance between the limiting piece 2 and the guide strip 1 is greater than 0 mm, the guide strip 1 can have a small amount of movement along the length direction thereof.

In addition, the orthogonal projection of the limiting segment 211 and the orthogonal projection of the guide groove 12 do not overlap along the length direction of the guide strip 1, therefore, the limiting segment 211 will not contact the chain 3, and will not affect the normal operation of the chain 3.
