Description

Technical Field

[0001] The utility model relates to the technical field of machine processing feeding, in particular to a feeding device which is convenient for operators to feed materials on a production line. Background Art

[0002] At present, automated loading devices are often needed in the process of industrial production. The stacked materials are arranged in order and transported to the designated location one by one through the loading device. For example, a loading device for conveying screws is provided in the Chinese utility model patent "A Screw Loading Device" with reference to patent number CN202321982814.0 (publication number CN220222753U).

[0003] However, the above-mentioned feeding device often requires an operator to approach and feed the material into the material bin of the feeding device before it can operate, which makes this type of feeding device have certain defects when used in some production lines. Figure 1 Use under the conditions shown, Figure 1 The loading device 1' can arrange the materials 12' in the silo 11' in order and transport them to the discharge port 13' one by one, so that the robot arm 2' can continuously grab the materials 12' at the discharge port 13' and transfer them to the processing equipment 3'. The loading device 1' and the robot arm 2' are both part of the entire production line, so the above devices are surrounded by the grid fence 4' within the range of the production line.

[0004] When the material 12' in the silo 11' of the feeding device 1' is completely consumed and needs to be replenished by the operator, the following two solutions can usually be adopted: first, the operator directly enters the range surrounded by the grid fence 4' and comes to the vicinity of the feeding device 1' to feed the material, but there is a risk of the operator being accidentally injured by the working robot arm 2' in this solution; second, the production line is suspended to stop the robot arm 2' from working, and then enters the range surrounded by the grid fence 4' and comes to the vicinity of the feeding device 1' to feed the material, but this solution will cause the robot arm 2' to be unable to work non-stop, which will affect the production rhythm and even lead to a reduction in production efficiency, especially when there are some equipment with a long startup time on the production line, which is more likely to lead to a reduction in production efficiency. Therefore, further improvements are needed. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a feeding device that can ensure that operators can safely feed materials while the production line is working continuously, in view of the above-mentioned existing technical status.

[0006] The second technical problem to be solved by the utility model is to provide a production line using the feeding device in view of the above-mentioned existing technical status.

[0007] The technical solution adopted by the utility model to solve the first technical problem is: a loading device, which is located on the inner side of the fence and includes a silo for containing materials to be processed, and is characterized in that: it also includes a feeding mechanism that allows operators to directly feed materials into the silo from the outside of the fence, and the feeding mechanism includes a feeding part exposed on the outside of the fence, a discharging part located on the inside of the fence, and a material channel connecting the two, and correspondingly, the fence is provided with an opening for the feeding part to at least partially pass through.

[0008] In order to avoid damage to the material to be processed when it falls into the silo, preferably, the discharge portion is at least partially connected to the silo. Such a design is based on the consideration that the silo usually has an opening facing upwards, and the discharge portion is arranged above the silo without being connected to ensure that the material to be processed can fall into the silo. However, due to the high drop, the material to be processed may cause greater damage due to collision when falling into the silo, especially the material to be processed made of metal materials is more likely to be damaged. Therefore, the discharge portion is arranged to be at least partially connected to the silo to minimize damage to the material to be processed when it falls into the silo.

[0009] In order to enable the material channel to transport the material to be processed, preferably, the material channel is in the shape of a tube, and the feed part and the discharge part are openings located at both ends of the material channel. According to actual needs, the material channel can also be set as a structure such as a track, and then the material to be processed is transported by a moving part that can move along the track. The material channel is set as a tube because this structure is relatively simpler and more reliable under the premise of being able to meet the use requirements.

[0010] It is further designed that in order to enable the material to be processed to slide relatively smoothly into the silo along the material channel, preferably, the material channel is inclined upward around the discharge portion and has an inclination angle α relative to the horizontal plane, and 5°≤α≤60°. As is well known, static friction will be generated between the material to be processed and the material channel, and only by destroying this static friction can the material to be processed slide along the material channel. The friction coefficient is usually related to the friction angle. Under a certain friction coefficient, when the material channel is tilted to the friction angle, the material to be processed can slide down along the material channel at a uniform speed. In industrial production, depending on the material, the friction coefficient between the material to be processed and the material channel is usually in the range of about 0.1 to 1.6, and the corresponding friction angle range is about 5° to 60°. Therefore, the inclination angle α of the material channel relative to the horizontal plane is set to 5°≤α≤60°. In addition, according to actual conditions, for example, according to the materials of the material to be processed and the material channel, and the shape of the material to be processed, a suitable angle can be selected within this range to set the material channel. For example, if the material to be processed is a sphere, a relatively small angle can be selected.

[0011] In order to facilitate the operator to put the material to be processed into the feed part, preferably, the periphery of the feed part at least partially expands outward to form a trumpet shape with the opening facing upward. Such a design enables the operator to easily put as much material as possible into the feed part.

[0012] In order to support the feeding mechanism, preferably, the feeding part is connected to the periphery of the opening. With such a design, a first support point is formed between the feeding part and the periphery of the opening, and no additional support structure is required to support the feeding mechanism, which is relatively simple and convenient. In addition, according to actual needs, the discharging part can be connected to a part of the silo to form a second support point to further enhance the stability of the feeding mechanism support.

[0013] The technical solution adopted by the utility model to solve the second technical problem is: the production line includes a plurality of working stations located inside the fence, including:

[0014] The loading station is provided with a loading device for loading the materials to be processed;

[0015] The processing station is provided with a processing mechanism for processing the material to be processed fed by the feeding device;

[0016] Features:

[0017] The feeding device is the feeding device as described above;

[0018] The workstation also includes:

[0019] A feeding station is arranged upstream of the loading station, and the feeding station is provided with a feeding mechanism of the loading device;

[0020] The transfer station is provided with at least one robot, which constitutes a transfer component for transferring the material to be processed between the above-mentioned loading station and the processing station.

[0021] In order to be able to process the material to be processed, preferably, the processing mechanism includes an installation platform for placing the material to be processed, the installation platform has a correspondingly installed pressing part and a driving part connected to the pressing part, and the driving part can drive the pressing part to move between an initial position and a final position to complete the assembly action of the material to be processed.

[0022] In order to facilitate the robot to grab the material to be processed, preferably, the loading device includes a feeding mechanism for the robot to grab the material to be processed, and the feeding mechanism is located at the upper part of the silo. Correspondingly, the loading device also includes a feeding mechanism for loading the material to be processed onto the feeding mechanism. The feeding mechanism can arrange the materials to be processed one by one to the designated position, and the feeding mechanism is provided to load the materials to be processed from the silo to the feeding mechanism, and the feeding mechanism will arrange the materials to be processed one by one to the designated position so that the robot can grab them.

[0023] Further design, in order to be able to load the material to be processed from the silo to the unloading mechanism, preferably, the bottom surface of the silo is inclined toward the direction close to the unloading mechanism, and correspondingly, the loading mechanism also includes a loading piece located between the unloading mechanism and the silo, the upper surface of the loading piece is parallel to the bottom surface of the silo, and the loading mechanism also includes a driving mechanism for switching the loading piece between the receiving station and the unloading station: when the loading piece is located at the receiving station, the upper surface of the loading piece is engaged with the bottom surface of the silo; when the loading piece is located at the unloading station, the upper surface of the loading piece is engaged with the upper surface of the unloading mechanism. Since the bottom surface of the silo is inclined toward the direction close to the unloading mechanism, the material to be processed moves toward the unloading mechanism to the loading piece located at the receiving station, and then the loading piece is driven to the unloading station by the driving mechanism to unload the material to be processed to the unloading mechanism.

[0024] Compared with the prior art, the advantages of the utility model are: through the feeding mechanism of the feeding device, the operator can directly feed materials into the silo of the feeding device outside the fence, so that the production line using the feeding device can work continuously while ensuring the safety of the operators in feeding work, thereby ensuring the safety of the operators and the production efficiency of the production line.

[0035] The present invention is further described in detail below in conjunction with specific embodiments.

[0036] like Figures 2 to 8 As shown in FIG. , it is a preferred embodiment of the present utility model. Figure 2 As shown, the feeding device 1 in this embodiment is located inside the fence 2, including a silo for containing the material M to be processed, and also includes a feeding mechanism 12 that allows operators to directly feed materials into the silo 11 outside the fence 2. The feeding mechanism 12 includes a feeding portion 13 exposed outside the fence 2, a discharging portion 14 located inside the fence 2, and a material channel 15 connecting the two. Correspondingly, as shown in FIG. Figure 3 As shown, the fence 2 is provided with an opening 21 for the feed portion 13 to at least partially pass through. In order to enable the material channel 15 to transport the material M to be processed, the material channel 15 in this embodiment is in the shape of a tube, and the feed portion 13 and the discharge portion 14 are openings located at both ends of the material channel 15. Figure 4 As shown, in order to facilitate the operator to put the material M to be processed into the feed part 13, the outer periphery of the feed part 13 is at least partially expanded and extended outward to form a trumpet shape with the opening facing upward. Furthermore, in order to enable the material M to be processed to slide relatively smoothly along the material channel 15 into the silo 11, the material channel 15 is inclined upward around the discharge part 14 and has an inclination angle α relative to the horizontal plane, and 5°≤α≤60°. Since the friction coefficient between the material M to be processed and the material channel in this embodiment is about 0.5, and the material M to be processed is a cylindrical bushing, setting α to 20° can make the material M to be processed slide relatively smoothly into the silo 11. In order to avoid damage to the material M to be processed when it falls into the silo 11, as shown in FIG. Figure 4As shown, the silo 11 in this embodiment extends upwardly and obliquely toward the fence 2 to form a receiving plate, and the discharge portion 14 is partially connected to the receiving plate of the silo 11, so as to prevent the material M to be processed from falling directly into the bottom of the silo 11 and causing unnecessary damage. In addition, the discharge portion 14 is partially connected to the receiving plate to form a first support point, and the feed portion 13 is connected to the periphery of the opening 21 to form a second support point. The first support point and the second support point work together to ensure the stability of the feed mechanism 12.

[0037] Furthermore, the production line in this embodiment includes a plurality of workstations located inside the fence 2, including: a loading station provided with a loading device 1 for loading the material M to be processed; a processing station provided with a processing mechanism 3 for processing the material M to be processed loaded by the loading device 1; a feeding station provided upstream of the loading station and provided with a feeding mechanism 12 of the loading device 1; a transfer station provided with at least one robot 4, the robot 4 constituting a transfer component for transferring the material M to be processed between the loading station and the processing station. Figure 7 As shown, the processing mechanism 3 in this embodiment includes an installation platform 31 for placing the material M to be processed. The installation platform 31 has a correspondingly installed pressing part 32 and a driving part 33 connected to the pressing part 32. The driving part 33 can drive the pressing part 32 to move between the initial position and the final position to complete the assembly action of the material M to be processed.

[0038] See also Figure 8In order to facilitate the robot 4 to grab the material M to be processed, the feeding device 1 in this embodiment includes a feeding mechanism 16 for the robot 4 to grab the material M to be processed. The feeding mechanism 16 is located on the upper part of the silo 11 and can arrange the materials M to be processed one by one to the designated position for the robot 4 to grab. Correspondingly, the feeding device 1 also includes a feeding mechanism 17 for feeding the material M to be processed to the feeding mechanism 16. The bottom surface of the silo 11 in this embodiment is inclined toward the direction close to the feeding mechanism 16. Correspondingly, the feeding mechanism 17 also includes a feeding piece 171 located between the feeding mechanism 16 and the silo 11, and the upper surface of the feeding piece 171 is parallel to the bottom surface of the silo 11. The unloading mechanism 16 in this embodiment is also provided with four unloading platforms 161 whose upper surfaces are parallel to the bottom surface of the silo 11. The upper surface of each unloading platform 161 is also parallel to the bottom surface of the silo 11. Correspondingly, the number of loading pieces 171 is the same as the number of unloading platforms 161, and the two are arranged alternately and spaced apart from each other. At the same time, the two correspond to each other and gradually rise toward the designated unloading position of the unloading mechanism 16. The unloading platforms 161 are fixedly connected to the housing of the loading device 1, and each loading piece 171 is connected to the guide rail G and can move up and down along the guide rail G at the same time under the drive of the driving mechanism 172, so that the loading piece 171 can switch between the material receiving station and the unloading station. When the loading piece 171 is located at the material receiving station, the upper surfaces of the four loading pieces 171 are respectively engaged with the bottom surface of the silo 11 and the upper surfaces of the corresponding next-level unloading platforms 161; when the loading piece 171 is located at the unloading station, the upper surfaces of the four loading pieces 171 are respectively engaged with the upper surfaces of the corresponding next-level unloading platforms 161.

[0039] Taking the loading member 171 at the lowest position as an example, the use process of the loading mechanism 17 of the loading device 1 provided in this embodiment is as follows:

[0040] like Fig. 9 As shown, at this time, the loading piece 171 is located at the material receiving station, and the upper surface of the loading piece 171 is engaged with the bottom surface of the silo 11. Since the bottom surface of the silo 11 is inclined toward the direction close to the unloading mechanism 16, the material M to be processed can slide onto the upper surface of the loading piece 171; under the drive of the driving mechanism 172, the loading piece 171 moves upward along the guide rail G to the unloading station, as shown in FIG. Fig.10 As shown, at this time, the upper surface of the loading member 171 is engaged with the upper surface of the corresponding unloading platform 161 at the same level. Since the upper surface of the loading member 171 is parallel to the bottom surface of the silo 11, the material M to be processed can be moved from the upper surface of the loading member 171 to the upper surface of the unloading platform 161. Therefore, the loading mechanism can load the material M to be processed in the silo 11 step by step upward to the designated unloading position of the unloading mechanism 16.
