Description

Technical Field

[0001] This invention relates to a transport vehicle. Background Technology

[0002] The core function of a conveyor is to provide a connection and adaptation structure for items with a high center of gravity or a small bottom support structure, so as to ensure that the items are placed stably on the conveyor and can be driven by the conveyor to complete the conveying operation.

[0003] Existing conveying carriers are mostly one-piece structures with internal perforations for accommodating or limiting items. These perforations are designed to mimic the shape of the items and are often adapted by combining the shapes of two different items. For example, the continuous conveying carrier described in the Chinese patent (publication number: CN110844505B) authorized on October 29, 2024, can not only establish a stable connection between the conveying surface and the cup-shaped product, but also adapt to cup-shaped products with different cup body types.

[0004] However, existing conveyor systems based on contour design have significant limitations: First, they are compatible with a limited range of items. Even with contour designs that incorporate more item shapes within the perforated structure, they are still limited by the space and structural characteristics of the perforated structure, making it impossible to achieve full coverage of multiple categories. Second, their poor versatility leads to high operating costs. If a certain type of item cannot be placed using existing systems, the entire batch of systems must be discarded and replaced with entirely new, compatible systems. This undoubtedly increases the company's operating costs and is detrimental to cost control and efficient production. Summary of the Invention

[0005] The technical problem to be solved by this invention is how to expand the types of articles compatible with transport vehicles.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: the conveying carrier includes a mold sleeve and a mold box. The top of the mold sleeve is provided with a groove I for installing the mold box. The bottom of the mold box is embedded in the groove I. The mold box and the mold sleeve are limited by a slot structure. The top of the mold box is provided with a groove II for accommodating items. The mold box is provided with a limiting part I. The limiting part I is located on both sides of the groove II and protrudes above the groove II. The area for accommodating items between the limiting parts I is located above the groove II. The inner surface of the limiting part I is continuously transitioned to the inner surface of the mold box at the groove II.

[0007] The overall design concept of the above technical solution is to improve the conveyor carrier from an integrated structure to a modular composite structure, with the mold sleeve and mold box assembled using a quick-release method. The mold sleeve serves as the support for the entire carrier, while the mold box serves as the carrying structure; the two can be flexibly assembled. The groove II of the mold box can be designed as a one-to-one dedicated structure or a one-to-many compatible structure. When the existing mold box cannot adapt to the target item, only the compatible mold box needs to be replaced, and the original mold sleeve can be retained for continued use. In this way, the carrier can be adapted and updated at a lower cost, effectively improving its compatibility. It is worth noting that the volume of the mold box is much smaller than that of the mold sleeve, and its manufacturing cost accounts for a very small percentage of the overall carrier production cost. Compared to replacing the entire carrier, partially replacing the mold box maximizes the expansion of the compatibility range while optimally controlling costs. Therefore, this composite structure can achieve compatibility with multiple categories of items.

[0008] The area between limiting parts I and the groove II together form the space for containing the item. The core function of the groove II is to provide a limiting structure that fits the bottom contour of the item, so that the bottom of the item is supported in the vertical direction and limited in the horizontal direction. The area between limiting parts I further strengthens the limiting effect of the item in the horizontal direction.

[0009] To ensure the stability of the limiting part I, its mechanical strength needs to be improved. Therefore, the mold sleeve is provided with supporting parts, which are located on both sides of the groove I and protrude above the groove I. The limiting part I is located between the supporting parts and is movably connected to the supporting parts. The supporting parts fit tightly against the limiting part I, which is equivalent to increasing the structural dimension at the limiting part I, thereby improving the mechanical performance of the limiting part I.

[0010] To further enhance the tightness of the connection between the limiting part I and the supporting part, a limiting protrusion is provided on the outer side of the limiting part I, and a limiting groove is provided on the inner side of the supporting part. The limiting protrusion is movably installed within the limiting groove. This design not only ensures a firm fit between the two but also restricts their relative movement around the circumference of the groove II, preventing misalignment.

[0011] Based on the limiting part I, a clamping function for the object can be added to improve the horizontal limiting stability. The preferred structure for achieving the clamping function is that the inner side of the limiting part I is provided with an inner flange I for clamping the object. The inner flange I fits tightly against the object, and the clamping effect is formed at this position by the elastic deformation of the limiting part I.

[0012] To enhance the connection between the mold and the item, the mold is equipped with a limiting part II. The limiting part II is located on both sides of the groove II and protrudes above it. The limiting part II and the limiting part I are alternately distributed around the groove II. The inner surface of the limiting part II is disconnected from the inner surface of the mold in the groove II. An inner flange II for clamping the item is provided on the inner side of the limiting part II. The limiting part II can elastically deform relative to the mold body. Due to the design that the inner surface of the limiting part II is disconnected from the inner surface of the mold in the groove II, the free range of elastic deformation of the limiting part II is greater than that of the limiting part I. Although the limiting part II reduces the open area above the groove II, the relatively closed area formed in the middle after its combination with the limiting part I can act as an extension of the groove II in the vertical direction. The item is not only effectively constrained by the groove II but also by the dual constraints of the limiting parts I and II. Furthermore, when the item is between the two limiting parts II, the limiting parts II are in a deformed state and tend to move towards the middle of the groove II. The inner flange II forms a clamping effect on the item, thereby improving the connection stability between the item and the mold box.

[0013] This technical solution features a quick-release assembly design, suitable for both conveyor chain and magnetic levitation conveying scenarios. The magnetic levitation conveying equipment has a moving part structure; adaptation can be achieved simply by designing the connection structure between the carrier and this moving part. Therefore, the conveying carrier also includes a base, and the mold sleeve is movably connected to the base using a quick-release mechanism.

[0014] A preferred quick-release structure includes unlocking components on both sides of the base. Each unlocking component comprises a positioning block, a trigger, and a spring. The trigger is movably mounted on the positioning block in a swing-like manner. The spring is located between one end of the trigger and the positioning block. The bottom of the mold sleeve has a positioning groove with a cross-sectional profile identical to that of the positioning block. The mold sleeve has a connecting rod located within the positioning groove. The other end of the trigger is movably connected to the connecting rod. The working principle of this quick-release structure is as follows: when the trigger is pulled, the engagement between the trigger and the connecting rod is released, allowing the mold sleeve to be directly removed from the base. When the trigger is in its natural state, placing the mold sleeve on the base and pressing it will engage the connecting rod with the reset trigger, achieving a quick connection between the mold sleeve and the base. The base can be fixedly connected to the moving part of a magnetic levitation conveyor.

[0015] Precise alignment between the mold sleeve and the base is a prerequisite for the reliable operation of the quick-release structure. Therefore, the optimized design adds a positioning guide structure. The base has positioning posts, and the mold sleeve has positioning holes, with the positioning posts embedded in the positioning holes. This structure, together with the positioning guide structure composed of positioning grooves and positioning blocks, ensures smooth alignment between the mold sleeve and the base.

[0016] The present invention adopts the above-mentioned technical solution: by combining structural design, the loading structure and support structure that adapt to the outline of the item are separated, and only the loading structure needs to be replaced to expand the types of compatible items; at the same time, the partial replacement method effectively reduces the cost of use.

Detailed Implementation

[0018] The first embodiment of the present invention, as follows: Figure 1 , 2 As shown in Figures 3, 4, and 5.

[0019] The conveying carrier includes a mold sleeve 1, a mold box 9, and a base 16. The mold sleeve 1 and the base 16 are assembled in a quick-release manner.

[0020] The outer dimensions of the mold sleeve 1 are larger than those of the mold box 9, and the mold box 9 is mounted on top of the mold sleeve 1. The top of the mold sleeve 1 has a groove I2 for mounting the mold box 9, and the bottom of the mold box 9 is embedded in the groove I2. On the side of the mold box 9, near the bottom, there is a protrusion 3, which is spaced apart around the center line of the mold box 9. The mold sleeve 1 has an annular groove 4 around the bottom of the groove I2. The protrusion 3 and the annular groove 4 are correspondingly fitted together. The protrusion 3, when embedded in the annular groove 4, secures the mold box 9 to the mold sleeve 1. The protrusion 3 and the annular groove 4 form a retaining groove structure.

[0021] The top of the mold box 9 has a groove II 10 for accommodating items. The groove II is designed based on the contour of the bottom of the item, so that the item fits snugly against the mold box 9 when its bottom is placed in the groove II 10. The upper part of the mold box 9 has two limiting parts I 11 and two limiting parts II 14, which are alternately distributed around the center line of the groove II 10. The limiting parts I 11 are located on both sides of the groove II 10 and protrude above it, and the limiting parts II 14 are located on both sides of the groove II 10 and protrude above it. An area for accommodating items is formed between the limiting parts I 11 and the limiting parts II 14, and this area is located above the groove II 10. The inner surfaces of the limiting parts I 11 and II 14 are designed to fit the item. The contour-following design ensures a continuous transition between the inner surface of the limiting part I11 and the inner surface of the mold 9 at the groove II10. A gap is provided between the limiting part II14 and the lower part of the mold 9, which disconnects the inner surface of the limiting part II14 from the inner surface of the mold 9 at the groove II10. Due to the gap structure, the elastic deformation capacity of the limiting part II14 relative to the lower part of the mold 9 is greater than that of the limiting part I11 relative to the lower part of the mold 9. Therefore, the free range of elastic deformation of the limiting part I11 is smaller than that of the limiting part II14.

[0022] The mold sleeve 1 is provided with support parts 5, which are used to enhance the mechanical strength of the limiting parts I11. The support parts 5 are located on both sides of the groove I2 and protrude above the groove I2. There are two support parts 5. When the bottom of the mold box 9 is embedded in the groove I2, the two limiting parts I11 are located between the two support parts 5, and the limiting parts I11 are movably connected to the support parts 5. The limiting parts I11 are subject to the limiting and supporting effects of the support parts 5 on their outer sides. A limiting protrusion 12 is provided on the outer side of the limiting part I11, and a limiting groove 6 is provided on the inner side of the support part 5. When the limiting part I11 is connected to the support part 5, the limiting protrusion 12 is movably installed in the limiting groove 6.

[0023] The inner side of the limiting part I11 is provided with an inner flange I13 for clamping the item, and the inner side of the limiting part II14 is provided with an inner flange II15 for clamping the item. When the item is placed in the groove II10, the inner flanges I13 and II15 will clamp the item.

[0024] The base 16 has a flat structure and is movably connected to the mold sleeve 1 via a quick-release mechanism. This quick-release mechanism includes unlocking components distributed on the base 16 and a positioning groove 7 and connecting rod 8 disposed on the mold sleeve 1. Specifically, unlocking components are provided on both sides of the base 16. Each unlocking component includes a positioning block 17, a trigger 18, and a spring. The positioning blocks 17 are fixedly mounted on the base 16, with two symmetrically distributed blocks 17 on the base 16. The trigger 18 is movably mounted on the positioning blocks 17 in a swinging manner. The spring is located between one end of the trigger 18 and the positioning block 17, and the spring is always in a compressed state. In its natural state, the trigger 18 is pushed to its limit position by the spring, and the trigger 18 is tilted relative to the positioning blocks 17, with one end of the trigger 18 away from the positioning blocks 17 and the other end close to them. Pressing one end of the trigger 18 moves the other end away from the positioning blocks 17. The other end of the trigger 18 has a protruding structure for attaching the connecting rod 8.

[0025] The bottom of the mold sleeve 1 has two symmetrically distributed positioning grooves 7, the cross-sectional profile of which is the same as that of the positioning block 17. A connecting rod 8 is provided on the mold sleeve 1, located within the positioning grooves 7. The mold sleeve 1 is placed on the base 16, with each positioning block 17 embedded in a positioning groove 7. Pressing the mold sleeve 1 causes the connecting rod 8 to slide relative to the other end of the trigger 18 until the protruding structure at the other end of the trigger 18 catches the connecting rod 8, thus achieving a movable connection between the other end of the trigger 18 and the connecting rod 8. The base 16 has four positioning posts 19, and the mold sleeve 1 has four positioning holes 20. The positioning posts 19 are embedded in the positioning holes 20. After the trigger 18 is connected to the connecting rod 8, the mold sleeve 1 and the base 16 are combined, with the positioning posts 19 embedded in the positioning holes 20. By pressing one end of the trigger 18 and disengaging the other end from the connecting rod 8, the mold sleeve 1 can be removed, thus detaching the mold sleeve 1 from the base 16.
