Description

Technical Field

[0001] The utility model relates to the technical field of food and drug packaging machinery and equipment, and particularly relates to a carrier conveying device. Background Art

[0002] At present, in the production process of injection pens, it is necessary to transport the pen caps and pen dosages of the injection pens between the front-end feeding mechanism and the rear-end material taking mechanism. At present, the transportation of pen caps and pen dosages between the front-end feeding mechanism and the rear-end material taking mechanism is generally carried out manually. The manual efficiency is low, the labor intensity is high, the transportation accuracy is poor, and it is easy to cause the material taking mechanism to fail to take materials successfully. There are also carrier conveying systems used for transporting pen caps and pen dosages. However, the existing carrier conveying systems either adopt one or more rows of carrier conveying mechanisms or adopt a circulating carrier conveying mechanism. The carriers are all installed on the conveying mechanism. After the carriers are out of stock, it will be difficult to replenish the injection pens conveyed in rows, so it is difficult to meet the requirements of the rear-end material taking mechanism for taking materials in rows, and it is difficult to avoid the rear-end material taking mechanism from taking an empty carrier out of stock; moreover, in order to recycle the carriers, the multi-row carrier conveying mechanism and the circulating carrier conveying mechanism will be large in volume and occupy a large space, and it is difficult to meet the installation requirements of limited space. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a carrier conveying device that meets the requirements of the material taking mechanism for taking materials in rows, avoids the material taking mechanism from taking an empty carrier out of stock, improves the utilization rate of the carriers, is small in volume, occupies a small space, and is conducive to meeting the installation requirements of limited space.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A carrier conveying device includes a first carrier conveying mechanism, a second carrier conveying mechanism, a first carrier return area and a second carrier return area. The first carrier conveying mechanism and the second carrier conveying mechanism are arranged in parallel and are connected through the first carrier return area and the second carrier return area to form a carrier circulation loop. The first carrier return area is provided with a first carrier positioning mechanism and a first pushing mechanism, and the second carrier return area is provided with a second carrier positioning mechanism and a second pushing mechanism. The first pushing mechanism is used to push the row of carriers on the second carrier conveying mechanism towards the first carrier positioning mechanism and the first carrier conveying mechanism, and the second pushing mechanism is used to push the whole row of carriers on the first carrier conveying mechanism and the specified serial numbers towards the second carrier positioning mechanism and the second carrier conveying mechanism.

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

[0007] The first vehicle positioning mechanism includes a positioning platform and a plurality of positioning components. The positioning platform is docked between the first vehicle conveying mechanism and the second vehicle conveying mechanism. Each of the positioning components is arranged on the positioning platform and arranged side by side along the conveying directions of the first vehicle conveying mechanism and the second vehicle conveying mechanism.

[0008] The positioning component includes a linear guiding part and a locking member. The linear guiding part is arranged on the positioning platform and perpendicular to the first vehicle conveying mechanism and the second vehicle conveying mechanism. A mating part that slidably cooperates with the linear guiding part is provided at the bottom of the vehicle. The locking member is arranged on the positioning platform and is used to lock and release the vehicle.

[0009] The linear guiding part is in a groove shape, and the locking member is arranged on the bottom wall of the linear guiding part.

[0010] The structure of the second vehicle positioning mechanism is the same as that of the first vehicle positioning mechanism.

[0011] The second pushing mechanism includes a plurality of independently operating telescopic pushing components. Each of the telescopic pushing components is arranged side by side along the conveying directions of the first vehicle conveying mechanism and the second vehicle conveying mechanism. A material detection mechanism is provided on one side of each of the telescopic pushing components for detecting whether there is a shortage of materials on the corresponding vehicle.

[0012] The first pushing mechanism includes a push plate and a telescopic driving component. The telescopic driving component is connected to the push plate and is used to drive the push plate to push the vehicles in a row.

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

[0014] An absorbing mechanism is provided on the other side of the second vehicle conveying mechanism relative to the second vehicle positioning mechanism. The absorbing mechanism is used to absorb the vehicles on the second vehicle positioning mechanism and convey them to the second vehicle conveying mechanism.

[0015] A vehicle conveying method is carried out by using the above-mentioned vehicle conveying device. The conveying directions of the first vehicle conveying mechanism and the second vehicle conveying mechanism are opposite, and the method includes the following steps:

[0016] S1. The empty vehicles in a row are positioned by the first vehicle positioning mechanism and then loaded.

[0017] S2. The loaded vehicles in a row are pushed by the first pushing mechanism or transferred to the first vehicle conveying mechanism by other mechanisms, and then conveyed by the first vehicle conveying mechanism to the side of the second pushing mechanism.

[0018] S3. Detect whether there is a shortage of carriers in the row of carriers on the side of the second pushing mechanism. If there is an empty carrier with a shortage of materials, the empty carrier is pushed by the second pushing mechanism to the second carrier conveying mechanism until there is no shortage of materials in the row of carriers on the side of the second pushing mechanism. Then, the second pushing mechanism pushes the row of carriers on the side as a whole to the second carrier positioning mechanism, and the carrier is unloaded after being positioned by the second carrier positioning mechanism.

[0019] S4. The empty carrier after unloading is pushed by the second pushing mechanism or transferred by other mechanisms to the second carrier conveying mechanism, 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 carriers to the first carrier positioning mechanism.

[0021] S6. Repeat S1 to S5.

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

[0023] In the carrier conveying device of the present utility model, the first carrier conveying mechanism and the second carrier conveying mechanism are connected through the first carrier return area and the second carrier return area to form a carrier circulation loop. That is to say, the carriers are not installed on the first carrier conveying mechanism and the second carrier conveying mechanism. During transportation, the carriers are only placed on the first carrier conveying mechanism and the second carrier conveying mechanism and are conveyed by them. In this way, if there is an empty carrier with a shortage of materials in the row of carriers on the side of the second pushing mechanism, the empty carrier can be pushed by the second pushing mechanism to the second carrier conveying mechanism, and the first carrier conveying mechanism then conveys the carriers forward, so that the rear loaded carriers fill the position of the original empty carrier until there is no shortage of materials in the row of carriers on the side of the second pushing mechanism. Then, the second pushing mechanism 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 the empty carriers and fill the empty spaces on the first carrier conveying mechanism, ensuring that the carriers entering the material taking station (the position where the second carrier positioning mechanism is located) are not short of materials, meeting the requirement of the material taking mechanism to take materials in a row, and avoiding the material taking mechanism taking an empty carrier with a shortage of materials. Moreover, the empty carriers can be recycled for reuse, improving the utilization rate of the carriers. Furthermore, the carrier circulation loop mainly formed by connecting the first carrier conveying mechanism, the second carrier conveying mechanism, the first carrier return area and the second carrier return area is small in volume and occupies little space, which is conducive to meeting the installation requirements of limited space.

[0024] For the vehicle conveying method of the present utility model, if there are empty vehicles lacking materials among the row of vehicles on the side of the second pushing mechanism, the empty vehicles can be pushed by the second pushing mechanism to the second vehicle conveying mechanism, and then the first vehicle conveying mechanism conveys the vehicles forward, enabling the loaded vehicles at the rear to fill the positions of the original empty vehicles until there is no lack of materials in the row of vehicles on the side of the second pushing mechanism. Then, the second pushing mechanism pushes the row of vehicles on the side as a whole to the second vehicle positioning mechanism for blanking. In other words, the empty vehicles can be removed and the empty positions can be filled on the first vehicle conveying mechanism, ensuring that the vehicles entering the material taking station (the position where the second vehicle positioning mechanism is located) are not lacking materials, meeting the requirement of the material taking mechanism to take materials in a row, and avoiding the material taking mechanism taking empty vehicles lacking materials. Moreover, the empty vehicles can be recycled by being transported back, improving the utilization rate of the vehicles. Brief Description of the Drawings

[0038] Embodiment 1:

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

[0040] The production process of this vehicle conveying device: First step, a row of empty vehicles 7 are positioned by the first vehicle positioning mechanism 3 and then loaded. Second step, the loaded row of vehicles 7 are pushed by the first pushing mechanism 5 or transferred by other mechanisms to the first vehicle conveying mechanism 1, and then conveyed by the first vehicle conveying mechanism 1 to the side of the second pushing mechanism 6. Third step, check whether the row of vehicles 7 on the side of the second pushing mechanism 6 is short of materials. If there are empty vehicles 7 lacking materials, the empty vehicles 7 are pushed by the second pushing mechanism 6 to the second vehicle conveying mechanism 2 until there is no shortage of materials in the row of vehicles 7 on the side of the second pushing mechanism 6. Then the second pushing mechanism 6 pushes the whole row of vehicles 7 on the side to the second vehicle positioning mechanism 4, and the vehicles 7 are positioned by the second vehicle positioning mechanism 4 and then unloaded. Fourth step, the empty vehicles 7 after unloading are 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. Fifth step, the first pushing mechanism 5 pushes the row of empty vehicles 7 to the first vehicle positioning mechanism 3. Sixth step, repeat the first step to the fifth step.

[0041] In this vehicle conveying device, the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 are connected through the first vehicle returning area and the second vehicle returning area to form a vehicle circulation loop. That is to say, the vehicle 7 is not installed on the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. During conveying, the vehicle 7 is only placed on the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 and is conveyed by the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. In this way, if there are empty vehicles 7 lacking materials among the row of vehicles 7 on the side of the second pushing mechanism 6, the empty vehicles 7 can be pushed by the second pushing mechanism 6 to the second vehicle conveying mechanism 2, and then the first vehicle conveying mechanism 1 conveys the vehicle 7 forward, enabling the loaded vehicle 7 behind to fill the position of the original empty vehicle 7 until there is no lack of materials among the row of vehicles 7 on the side of the second pushing mechanism 6. Then, the second pushing mechanism 6 pushes the row of vehicles 7 on the side as a whole to the second vehicle positioning mechanism 4 for material unloading. In other words, this vehicle conveying device can pick out the empty vehicles 7 and fill the empty spaces on the first vehicle conveying mechanism 1, ensuring that the vehicles 7 entering the material taking station (the position where the second vehicle positioning mechanism 4 is located) are not lacking materials, meeting the requirement for the material taking mechanism to take materials in a row, and avoiding the material taking mechanism taking an empty vehicle 7 lacking materials. Moreover, the empty vehicles 7 can be recycled by being returned, improving the utilization rate of the vehicles 7. Furthermore, the vehicle circulation loop mainly formed by connecting the first vehicle conveying mechanism 1, the second vehicle conveying mechanism 2, the first vehicle returning area, and the second vehicle returning area is small in volume and occupies little space, facilitating meeting the installation requirements in a limited space.

[0042] Further, 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 so-called "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 vehicle return area and the second vehicle return area are arranged at intervals along the conveying direction of the first vehicle conveying mechanism 1. Preferably, the first vehicle return area and the second vehicle return area are respectively 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 respectively located at both ends of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. It can be explained that: the first vehicle return area and the second vehicle return area are two areas respectively located between both ends of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. It can be that the first vehicle return area is located between one end of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2, and the second vehicle return area is located between the other end of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. Or it can be that one end of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 is located in the first vehicle return area, and the other end of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 is located in the second vehicle return area. That is to say, the first vehicle positioning mechanism 3 and the second vehicle positioning mechanism 4 can be arranged between the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 to make the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 spaced apart, or can be arranged on the first vehicle conveying mechanism 1 and / or the second vehicle conveying mechanism 2 to reduce the interval between the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2.

[0043] Further, as Figure 3 and Figure 4 shown, in this embodiment, the first vehicle positioning mechanism 3 includes a positioning platform 31 and a plurality of positioning components 32. The positioning platform 31 is docked between the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. Each positioning component 32 is arranged on the positioning platform 31 and is arranged side by side along the conveying directions of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2. The positioning platform 31 is docked between the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2, which is convenient for guiding the vehicle 7 on the second vehicle conveying mechanism 2 to the first vehicle positioning mechanism 3. Each positioning component 32 is arranged side by side along the conveying directions of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2, which is convenient for the first pushing mechanism 5 to push the row of vehicles 7 on the second vehicle conveying mechanism 2 to the row of positioning components 32 in a row, and is also convenient for the row of vehicles 7 on the row of positioning components 32 to be pushed to the first vehicle conveying mechanism 1 in a row, that is, it is convenient for both the second vehicle conveying mechanism 2 to discharge the row of vehicles 7 and the first vehicle conveying mechanism 1 to feed the row of vehicles 7.

[0044] Further, in this embodiment, the positioning assembly 32 includes a linear guiding portion 321 and a locking member 322. The linear guiding portion 321 is provided on the positioning platform 31 and is perpendicular to the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. A mating portion 71 slidably engaged with the linear guiding portion 321 is provided at the bottom of the carrier 7. The locking member 322 is provided on the positioning platform 31 and is used to lock and release the carrier 7. The linear guiding portion 321 facilitates guiding the carrier 7 between the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2, so that the carrier 7 is directionally guided along the linear guiding portion 321.

[0045] Further, in this embodiment, the linear guiding portion 321 is in a groove shape, and the locking member 322 is provided on the bottom wall of the linear guiding portion 321. The linear guiding portion 321 is in a T-shaped groove shape, a dovetail groove shape, etc.

[0046] Further, in this embodiment, the second carrier positioning mechanism 4 has the same structure as the first carrier positioning mechanism 3. This is convenient for manufacturing. However, the number of positioning assemblies 32 of the second carrier positioning mechanism 4 and the first carrier positioning mechanism 3 may be different.

[0047] Further, as Figure 5 shown, in this embodiment, the second pushing mechanism 6 includes a plurality of independently operating telescopic pushing assemblies 61. The telescopic pushing assemblies 61 are arranged side by side along the conveying direction of the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2. A material detection mechanism 62 is provided on one side of each telescopic pushing assembly 61 for detecting whether there is a lack of material on the corresponding carrier 7.

[0048] On the one hand, each telescopic pushing assembly 61 can operate independently, so that the carrier 7 can be selectively pushed out. When pushing the empty carrier 7 on the first carrier positioning mechanism 3, the loaded carrier 7 is not pushed. After all the carriers 7 in a row are not lacking in material, they are simultaneously pushed to the second carrier positioning mechanism 4. On the other hand, the material detection mechanism 62 is in signal connection with the corresponding telescopic pushing assembly 61, which is convenient for operating the telescopic pushing assembly 61 corresponding to the carrier 7 (empty carrier 7) with a specified serial number to push the carrier 7 with the specified serial number. The telescopic pushing assembly 61 can be a cylinder, an oil cylinder or an electric cylinder.

[0049] Further, as Figure 6 shown, in this embodiment, the first pushing mechanism 5 includes a push plate 51 and a telescopic driving assembly 52. The telescopic driving assembly 52 is connected to the push plate 51 and is used to drive the push plate 51 to push the carriers 7 in a row. The structure is simple and the processing is convenient. The telescopic driving assembly 52 can be a cylinder, an oil cylinder or an electric cylinder.

[0050] Further, in this embodiment, both the first carrier conveying mechanism 1 and the second carrier conveying mechanism 2 are mesh belt conveying mechanisms, and the rotating shafts of the mesh belt conveying mechanisms are horizontally arranged.

[0051] Further, in this embodiment, a suction mechanism 8 is provided on the side of the second vehicle conveying mechanism 2 opposite to the second vehicle positioning mechanism 4. The suction mechanism 8 is used to suck and convey the vehicle 7 on the second vehicle positioning mechanism 4 to the second vehicle conveying mechanism 2. Since the suction mechanism 8 is provided, the pushing distance of the second pushing mechanism 6 can be reduced, which is convenient for the selection of this mechanism.

[0052] Further, in this embodiment, the second pushing mechanism 6 is used to push the row of vehicles 7 on the first vehicle conveying mechanism 1 as a whole and the specified serial number in the direction of the second vehicle positioning mechanism 4 and the second vehicle conveying mechanism 2. The so-called specified 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 can also push the row of vehicles 7 on one side at the same time.

[0053] Further, in this embodiment, the locking member 322 is a suction attachment or an electric plug lock.

[0054] Embodiment 1:

[0055] Figure 7 An embodiment of the vehicle conveying method of the present utility model is shown. The vehicle conveying method of this embodiment is carried out by using the vehicle conveying device of Embodiment 1. The conveying directions of the first vehicle conveying mechanism 1 and the second vehicle conveying mechanism 2 are opposite, and the method includes the following steps:

[0056] S1. A row of empty vehicles 7 are loaded after being positioned by the first vehicle positioning mechanism 3;

[0057] S2. The loaded row of vehicles 7 are pushed by the first pushing mechanism 5 or transferred by other mechanisms to the first vehicle conveying mechanism 1, and then conveyed by the first vehicle conveying mechanism 1 to the side of the second pushing mechanism 6;

[0058] S3. Detect whether the row of vehicles 7 on the side of the second pushing mechanism 6 is short of materials. If there is an empty vehicle 7 lacking materials (such as Figure 7 shown as a1), the empty vehicle 7 is pushed by the second pushing mechanism 6 to the second vehicle conveying mechanism 2 (such as Figure 7 shown as a2) until there is no shortage of materials in the row of vehicles 7 on the side of the second pushing mechanism 6 (such as Figure 7 shown as a3). Then the second pushing mechanism 6 pushes the row of vehicles 7 on the side as a whole to the second vehicle positioning mechanism 4 (such as Figure 7 shown as a4), and the vehicle 7 is unloaded after being positioned by the second vehicle positioning mechanism 4;

[0059] S4. The empty vehicle 7 after unloading is 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;

[0060] S5. The first pushing mechanism 5 pushes the row of empty carriers 7 to the first carrier positioning mechanism 3;

[0061] S6. Repeat S1 to S5.

[0062] In this carrier conveying method, if there are empty carriers 7 lacking materials among 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, and then the first carrier conveying mechanism 1 conveys the carriers 7 forward, so that the rear loaded carriers 7 fill the positions of the original empty carriers 7 until there is no lack of materials 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 blanking. In other words, the empty carriers 7 can be removed and the empty positions can be filled on the first carrier conveying mechanism 1, which can ensure that the carriers 7 entering the material taking station (the position where the second carrier positioning mechanism 4 is located) are not lacking materials, meet the requirement of the material taking mechanism to take materials in a row, and avoid the material taking mechanism taking the empty carriers 7 lacking materials. Moreover, the empty carriers 7 can be recycled for reuse, improving the utilization rate of the carriers 7.

[0063] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
