Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment technology, specifically to a carrier conveying device and method. Background Technology

[0002] Currently, in the production process of injection pens, pen caps and metering units need to be transported between the front-end feeding mechanism and the rear-end picking mechanism. Currently, the transport of pen caps and metering units between these two mechanisms is generally done manually. This manual method is inefficient, labor-intensive, and has poor transport accuracy, easily causing the picking mechanism to fail to pick up the units successfully. While some systems use carrier conveyor systems for transporting pen caps and metering units, existing systems either employ single or multiple carrier conveyor mechanisms or circular carrier conveyor mechanisms. Since the carriers are all mounted on the conveyor mechanism, if a carrier runs out of material, it will be difficult to replenish the rows of injection pens being transported, thus failing to meet the requirement of the rear-end picking mechanism to pick up units in rows. This makes it difficult to avoid the rear-end picking mechanism picking up empty carriers. Furthermore, multi-carrier conveyor mechanisms and circular carrier conveyor mechanisms, due to the need for carrier recycling, result in large volumes and occupy a lot of space, making it difficult to meet the installation requirements of limited spaces. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a carrier conveying device and method that meets the requirements of the material picking mechanism to pick up materials in rows, avoids the material picking mechanism picking up empty carriers with insufficient materials, improves the utilization rate of carriers, has a small size, occupies little space, and is conducive to meeting the installation requirements of limited space.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A vehicle conveying device includes a first vehicle conveying mechanism, a second vehicle conveying mechanism, a first return area, and a second return area. The first and second vehicle conveying mechanisms are arranged in parallel and connected through the first and second return areas to form a vehicle circulation loop. The first return area is provided with a first vehicle positioning mechanism and a first pushing mechanism. The second return area is provided with a second vehicle positioning mechanism and a second pushing mechanism. The first pushing mechanism is used to push rows of vehicles on the second vehicle conveying mechanism toward the first vehicle positioning mechanism and the first vehicle conveying mechanism. The second pushing mechanism is used to push the entire row of vehicles on the first vehicle conveying mechanism and a designated serial number toward the second vehicle positioning mechanism and the second vehicle conveying mechanism.

[0006] As a further improvement to the above technical solution:

[0007] The first vehicle positioning mechanism includes a positioning platform and multiple positioning components. The positioning platform is connected between the first vehicle conveying mechanism and the second vehicle conveying mechanism. Each of the positioning components is disposed on the positioning platform and arranged side by side along the conveying direction of the first vehicle conveying mechanism and the second vehicle conveying mechanism.

[0008] The positioning component includes a linear guide and a locking element. The linear guide is provided on a positioning platform and is perpendicular to the first and second vehicle conveying mechanisms. The bottom of the vehicle is provided with a mating part that slides with the linear guide. The locking element is provided on the positioning platform and is used to lock and release the vehicle.

[0009] The linear guide portion is groove-shaped, and the locking element is located on the bottom wall of the linear guide portion.

[0010] The second vehicle positioning mechanism has the same structure as the first vehicle positioning mechanism.

[0011] The second pushing mechanism includes multiple independently operating telescopic pushing components. Each telescopic pushing component is arranged side by side along the conveying direction of the first carrier conveying mechanism and the second carrier conveying mechanism. Each telescopic pushing component is provided with a material detection mechanism on one side to detect whether there is a shortage of material on the corresponding carrier.

[0012] The first pushing mechanism includes a push plate and a telescopic drive assembly. The telescopic drive assembly is connected to the push plate and is used to drive the push plate to push the carriers in rows.

[0013] Both the first and second vehicle conveying mechanisms are mesh belt conveying mechanisms, and the rotating shaft of the mesh belt conveying mechanism is arranged horizontally.

[0014] The second vehicle conveying mechanism is provided with a suction mechanism on the other side of the second vehicle positioning mechanism. The suction mechanism is used to suction and convey the vehicle on the second vehicle positioning mechanism to the second vehicle conveying mechanism.

[0015] A vehicle transport method, using the aforementioned vehicle transport device, wherein the first vehicle transport mechanism and the second vehicle transport mechanism transport in opposite directions, includes the following steps:

[0016] S1. The rows of empty vehicles are positioned by the first vehicle positioning mechanism before being loaded with materials;

[0017] S2. The rows of loading carriers are pushed by the first pushing mechanism or transferred by other mechanisms to the first carrier conveying mechanism, and then conveyed by the first carrier conveying mechanism to the side of the second pushing mechanism;

[0018] S3. Detect whether the row of carriers on the side of the second pushing mechanism is short of material. If there are empty carriers that are short of material, the empty carriers are pushed by the second pushing mechanism to the second carrier conveying mechanism until the row of carriers on the side of the second pushing mechanism are not short of material. Then the second pushing mechanism pushes the row of carriers on the side as a whole to the second carrier positioning mechanism. The carriers are then positioned by the second carrier positioning mechanism and unloaded.

[0019] S4. After unloading, the empty carrier is pushed by the second pushing mechanism or transferred to the second carrier conveying mechanism by other mechanisms, and then conveyed by the second carrier conveying mechanism to the side of the first pushing mechanism.

[0020] S5. The first pushing mechanism pushes the row of empty vehicles to the first vehicle positioning mechanism;

[0021] S6. Repeat S1 to S5.

[0022] Compared with the prior art, the advantages of the present invention are as follows:

[0023] In the carrier conveying device of the present invention, the first carrier conveying mechanism and the second carrier conveying mechanism are connected through the first return area and the second return area to form a carrier circulation loop. That is to say, the carrier is not installed on the first carrier conveying mechanism and the second carrier conveying mechanism. During conveying, the carrier is simply placed on the first carrier conveying mechanism and the second carrier conveying mechanism and conveyed by the first carrier conveying mechanism and the second carrier conveying mechanism. In this way, if there are empty carriers lacking material in the row of carriers on the side of the second pushing mechanism, the empty carriers can be pushed to the second carrier conveying mechanism by the second pushing mechanism. The first carrier conveying mechanism then conveys the carriers forward so that the carriers behind fill the positions of the original empty carriers until there are no empty carriers in the row of carriers on the side of the second pushing mechanism. The second pushing mechanism then pushes the row of carriers on the side as a whole to the second carrier positioning mechanism for unloading. In other words, this carrier conveying device can remove empty carriers and fill them on the first carrier conveying mechanism, ensuring that all carriers entering the material handling station (where the second carrier positioning mechanism is located) are not short of material, meeting the requirement of the material handling mechanism to handle materials in rows, and avoiding the material handling mechanism picking up empty carriers that are short of material. Furthermore, empty carriers can be returned for recycling, improving the utilization rate of the carriers. Moreover, the carrier circulation loop, mainly formed by the first carrier conveying mechanism, the second carrier conveying mechanism, the first return area, and the second return area, is small in size and occupies little space, making it suitable for installation in limited spaces.

[0024] In the carrier conveying method of the present invention, if there are empty carriers lacking material in the row of carriers to the side of the second pushing mechanism, the empty carriers can be pushed by the second pushing mechanism to the second carrier conveying mechanism. The first carrier conveying mechanism then conveys the carriers forward, so that the carriers behind fill the positions of the original empty carriers, until all the carriers to the side of the second pushing mechanism are free of material. The second pushing mechanism then pushes the entire row of carriers to the second carrier positioning mechanism for unloading. In other words, empty carriers can be removed and filled on the first carrier conveying mechanism, ensuring that all carriers entering the picking station (where the second carrier positioning mechanism is located) are free of material, meeting the requirements of the picking mechanism for picking up materials in rows, and avoiding the picking mechanism picking up empty carriers lacking material. Furthermore, empty carriers can be returned for recycling, improving the utilization rate of the carriers. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Example 1:

[0039] Figures 1 to 6An embodiment of the vehicle conveying device of the present invention is shown. The vehicle conveying device of this embodiment includes a first vehicle conveying mechanism 1, a second vehicle conveying mechanism 2, a first return area and a second return area. The first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 are arranged in parallel and connected through the first return area and the second return area to form a vehicle circulation loop. The first return area is provided with a first vehicle positioning mechanism 3 and a first pushing mechanism 5. The second return area is provided with a second vehicle positioning mechanism 4 and a second pushing mechanism 6. The first pushing mechanism 5 is used to push a row of vehicles 7 on the second vehicle conveying mechanism 2 toward the first vehicle positioning mechanism 3 and the first vehicle conveying mechanism 1. The second pushing mechanism 6 is used to push the entire row of vehicles 7 on the first vehicle conveying mechanism 1 and a designated serial number toward the second vehicle positioning mechanism 4 and the second vehicle conveying mechanism 2.

[0040] The production process of this carrier conveying device is as follows: First, rows of empty carriers 7 are positioned by the first carrier positioning mechanism 3 and then loaded; Second, the loaded rows of carriers 7 are pushed by the first pushing mechanism 5 or transferred to the first carrier conveying mechanism 1 by other mechanisms, and then conveyed by the first carrier conveying mechanism 1 to the side of the second pushing mechanism 6; Third, it is detected whether the rows of carriers 7 on the side of the second pushing mechanism 6 are missing material. If there are empty carriers 7 missing material, the empty carriers 7 are pushed by the second pushing mechanism 6 to the second carrier conveying mechanism 2, until the second pushing mechanism 6... If all the rows of vehicles 7 on the side are in good condition, the second pushing mechanism 6 will push the rows of vehicles 7 on the side to the second vehicle positioning mechanism 4. After the vehicles 7 are positioned by the second vehicle positioning mechanism 4, they will be unloaded. In the fourth step, the unloaded empty vehicles 7 will be pushed by the second pushing mechanism 6 or transferred by other mechanisms to the second vehicle conveying mechanism 2, and then conveyed by the second vehicle conveying mechanism 2 to the side of the first pushing mechanism 5. In the fifth step, the first pushing mechanism 5 will push the rows of empty vehicles 7 to the first vehicle positioning mechanism 3. In the sixth step, the first to fifth steps will be repeated.

[0041] In this carrier conveying device, the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 are connected through the first return area and the second return area to form a carrier circulation loop. That is to say, the carrier 7 is not installed on the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. During conveying, the carrier 7 is simply placed on the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 and conveyed by the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. In this way, if there is an empty carrier 7 lacking material in the row of carriers 7 on the side of the second pushing mechanism 6, the empty carrier 7 can be pushed by the second pushing mechanism 6 to the second carrier conveying mechanism 2. The first carrier conveying mechanism 1 then conveys the carrier 7 forward so that the material-carrying carrier 7 behind fills the position of the original empty carrier 7, until there is no shortage of material in the row of carriers 7 on the side of the second pushing mechanism 6. Then the second pushing mechanism 6 pushes the row of carriers 7 on the side as a whole to the second carrier positioning mechanism 4 for unloading. In other words, this carrier conveying device can remove empty carriers 7 and fill them on the first carrier conveying mechanism 1, ensuring that all carriers 7 entering the material picking station (where the second carrier positioning mechanism 4 is located) are not short of material, meeting the requirement of the material picking mechanism to pick up materials in rows, and avoiding the material picking mechanism picking up empty carriers 7 that are short of material. Furthermore, empty carriers 7 can be returned for recycling, improving the utilization rate of carriers 7. Moreover, the carrier circulation loop, mainly formed by the first carrier conveying mechanism 1, the second carrier conveying mechanism 2, the first return area, and the second return area, is small in size and occupies little space, which is beneficial for meeting the installation requirements of limited space.

[0042] Furthermore, the first vehicle positioning mechanism 3 and the second vehicle positioning mechanism 4 are located between the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 (the "between" can be within the gap between the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2, or on the first vehicle conveying mechanism 1 or the second vehicle conveying mechanism 2). The conveying directions of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 are opposite, and the first return area and the second return area are arranged at intervals along the conveying direction of the first vehicle conveying mechanism 1. Preferably, the first return area and the second return area are located at both ends of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2, that is, the first vehicle positioning mechanism 3 and the second vehicle positioning mechanism 4 are located at both ends of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2, respectively. This can be explained as follows: the first return area and the second return area are two regions located between the two ends of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2, respectively. Alternatively, the first return area can be located between one end of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2, and the second return area can be located between the other ends of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. Or, one end of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 can be located in the first return area, and the other end of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 can be located in the second return area. In other words, the first carrier positioning mechanism 3 and the second carrier positioning mechanism 4 can be located between the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2, thus spacing them apart, or they can be located on the first carrier conveying mechanism 1 and / or the second carrier conveying mechanism 2, reducing the spacing between the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2.

[0043] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the first carrier positioning mechanism 3 includes a positioning platform 31 and multiple positioning components 32. The positioning platform 31 is connected between the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. Each positioning component 32 is disposed on the positioning platform 31 and arranged side by side along the conveying direction of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. The positioning platform 31 is connected between the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2, which facilitates the conveying of the carriers 7 on the second carrier conveying mechanism 2 to the first carrier positioning mechanism 3. The arrangement of each positioning component 32 along the conveying direction of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 facilitates the first pushing mechanism 5 to push the rows of carriers 7 on the second carrier conveying mechanism 2 to the rows of positioning components 32, and also facilitates the pushing of the rows of carriers 7 on the rows of positioning components 32 to the first carrier conveying mechanism 1. That is, it facilitates both the discharge of the rows of carriers 7 from the second carrier conveying mechanism 2 and the feeding of the rows of carriers 7 into the first carrier conveying mechanism 1.

[0044] Furthermore, in this embodiment, the positioning component 32 includes a linear guide portion 321 and a locking member 322. The linear guide portion 321 is mounted on the positioning platform 31 and is perpendicular to the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. The bottom of the carrier 7 is provided with a mating portion 71 that slides with the linear guide portion 321. The locking member 322 is mounted on the positioning platform 31 and is used to lock and release the carrier 7. The linear guide portion 321 facilitates the guiding of the carrier 7 between the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2, allowing the carrier 7 to be directionally guided along the linear guide portion 321.

[0045] Furthermore, in this embodiment, the linear guide portion 321 is groove-shaped, and the locking member 322 is disposed on the bottom wall of the linear guide portion 321. The linear guide portion 321 is T-shaped, dovetail-shaped, or the like.

[0046] Furthermore, in this embodiment, the second vehicle positioning mechanism 4 has the same structure as the first vehicle positioning mechanism 3, which facilitates manufacturing. However, the number of positioning components 32 in the second vehicle positioning mechanism 4 and the first vehicle positioning mechanism 3 may be different.

[0047] Furthermore, such as Figure 5 As shown, in this embodiment, the second pushing mechanism 6 includes multiple independently operating telescopic pushing components 61. Each telescopic pushing component 61 is arranged side by side along the conveying direction of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. Each telescopic pushing component 61 is provided with a material detection mechanism 62 on one side to detect whether there is a shortage of material on the corresponding carrier 7.

[0048] On the one hand, each telescopic pushing component 61 can operate independently, allowing for the selective deployment of carriers 7. When pushing an empty carrier 7 on the first carrier positioning mechanism 3, a loaded carrier 7 is not pushed. Only after all carriers 7 in the row are fully loaded are they simultaneously pushed to the second carrier positioning mechanism 4. On the other hand, the material detection mechanism 62 is signal-connected to the corresponding telescopic pushing component 61, facilitating the operation of the telescopic pushing component 61 corresponding to the specified number of carrier 7 (empty carrier 7), thus pushing the specified number of carrier 7. The telescopic pushing component 61 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0049] Furthermore, such as Figure 6 As shown, in this embodiment, the first pushing mechanism 5 includes a push plate 51 and a telescopic drive assembly 52. ​​The telescopic drive assembly 52 is connected to the push plate 51 and is used to drive the push plate 51 to push the carriers 7 in rows. The structure is simple and easy to manufacture. The telescopic drive assembly 52 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0050] Furthermore, in this embodiment, both the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 are mesh belt conveying mechanisms, and the rotation axis of the mesh belt conveying mechanism is arranged horizontally.

[0051] Furthermore, in this embodiment, the second carrier conveying mechanism 2 is provided with a suction mechanism 8 on the other side opposite to the second carrier positioning mechanism 4. The suction mechanism 8 is used to suction and convey the carrier 7 on the second carrier positioning mechanism 4 to the second carrier conveying mechanism 2. Because of the suction mechanism 8, the pushing distance of the second pushing mechanism 6 can be reduced, making it easier to select this mechanism.

[0052] Furthermore, in this embodiment, the second pushing mechanism 6 is used to push the entire row of vehicles 7 and the designated serial number on the first vehicle conveying mechanism 1 toward the second vehicle positioning mechanism 4 and the second vehicle conveying mechanism 2. The so-called designated serial number refers to the serial number of the empty vehicle 7 in the original row of vehicles 7. That is, the second pushing mechanism 6 can push only the empty vehicle 7, or it can push the row of vehicles 7 on one side at the same time.

[0053] Furthermore, in this embodiment, the locking element 322 is an adsorption element or an electric locking element.

[0054] Example 1:

[0055] Figure 7 This illustration shows an embodiment of the vehicle transport method of the present invention. The vehicle transport method of this embodiment uses the vehicle transport device of Embodiment 1, wherein the first vehicle transport mechanism 1 and the second vehicle transport mechanism 2 have opposite transport directions, and includes the following steps:

[0056] S1. The rows of empty vehicles 7 are positioned by the first vehicle positioning mechanism 3 before being loaded with materials;

[0057] S2. The loading carrier 7 is pushed by the first pushing mechanism 5 or transferred by other mechanisms to the first carrier conveying mechanism 1, and then conveyed by the first carrier conveying mechanism 1 to the side of the second pushing mechanism 6.

[0058] S3. Check if the rows of carriers 7 on the side of the second pushing mechanism 6 are short of material. If there are empty carriers 7 short of material (such as...) Figure 7 As shown in a1), the empty vehicle 7 is pushed by the second pushing mechanism 6 to the second vehicle conveying mechanism 2 (as shown in a1). Figure 7 As shown in a2), there is no shortage of materials up to the row of vehicles 7 on the side of the second pushing mechanism 6 (as shown in a2). Figure 7 As shown in a3), the second pushing mechanism 6 then pushes the row of vehicles 7 on the side as a whole to the second vehicle positioning mechanism 4 (as shown in a3). Figure 7 As shown in a4), the carrier 7 is unloaded after being positioned by the second carrier positioning mechanism 4;

[0059] S4. After unloading, the empty carrier 7 is pushed by the second pushing mechanism 6 or transferred by other mechanisms to the second carrier conveying mechanism 2, and then conveyed by the second carrier conveying mechanism 2 to the side of the first pushing mechanism 5.

[0060] S5, the first pushing mechanism 5 pushes the row of empty vehicles 7 to the first vehicle positioning mechanism 3;

[0061] S6. Repeat S1 to S5.

[0062] In this carrier conveying method, if there are empty carriers 7 lacking material in the row of carriers 7 on the side of the second pushing mechanism 6, the empty carriers 7 can be pushed by the second pushing mechanism 6 to the second carrier conveying mechanism 2. The first carrier conveying mechanism 1 then conveys the carriers 7 forward, so that the following carriers 7 fill the positions of the original empty carriers 7, until there is no shortage of material in the row of carriers 7 on the side of the second pushing mechanism 6. Then, the second pushing mechanism 6 pushes the row of carriers 7 on the side as a whole to the second carrier positioning mechanism 4 for unloading. In other words, empty carriers 7 can be removed and filled on the first carrier conveying mechanism 1, ensuring that the carriers 7 entering the picking station (where the second carrier positioning mechanism 4 is located) are all not lacking material, meeting the requirements of the picking mechanism for picking up materials in rows, and avoiding the picking mechanism picking up empty carriers 7 lacking material. Furthermore, empty carriers 7 can be returned for recycling, improving the utilization rate of the carriers 7.

[0063] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
