Description

Technical Field

[0001] This utility model relates to the field of toy processing technology, specifically to a switching feeding device with a counting function. Background Technology

[0002] Some small toys, such as gashapon toys or ball toys, are typically conveyed to packaging equipment via conveyor belts for centralized packaging after quality inspection. Since these types of toys are not individually packaged, hundreds of similar toys are usually placed in the same box for packaging. During packaging, manual counting of toys is easily affected by external factors, and the accuracy of the count cannot be completely guaranteed. Therefore, electronic counting equipment is generally introduced to solve the above problems.

[0003] For example, patent CN201210130420.2, "Photoelectric Counting Automatic Bag Counting and Packing Machine," describes a photoelectric counting automatic bag counting and packing machine that uses a photoelectric counting device to record the number of bags entering the main lower bag channel and inputs the detection information into a controller. The controller then controls the drive device to rotate the switching plate, thereby switching the bag distribution channel connected to the main lower bag channel, achieving automatic bag counting and packing. The use of a photoelectric counting device ensures accurate counting and eliminates packing errors. However, this type of photoelectric counting automatic bag counting and packing machine is not suitable for counting and conveying small toys. The main reason is that the packaging boxes are relatively large, and the output end of the packing machine is generally at a certain height difference from the bottom of the packaging box. After falling from these distribution devices, small toys undergo a period of free fall, resulting in a very rapid change in the toy's falling speed. Collisions between the falling toys and the bottom of the packaging box or other toys can easily cause deformation or scattering, directly affecting the subsequent sale of these toys. In response to this situation, the common industry practice is to adjust the distance between the bottom of the packaging box and these dispensing devices to reduce the impact of toys falling. However, this requires the packaging box to continuously descend as the number of toys increases, necessitating the use of an external lifting platform for loading, making the overall operation relatively cumbersome. Another method is to install a funnel-shaped mesh between the output end of these dispensing devices and the bottom of the packaging box, with the bottom of the funnel-shaped mesh extending into the packaging box. This funnel-shaped mesh helps to cushion the falling speed of the toys. However, this method of receiving toys with a funnel-shaped mesh can prevent toys from spreading outwards in the top area of ​​the packaging box, causing toys to accumulate inside the funnel-shaped mesh. Later, the funnel-shaped mesh needs to be manually removed and the toys sorted, which is quite troublesome. Utility Model Content

[0004] In order to overcome one of the shortcomings of the prior art, the purpose of this utility model is to provide a switching feeding device with a counting function. This switching feeding device with a counting function can reduce the falling speed of toys and protect them.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Reference Figures 1 to 4The illustrated switching feeding device with counting function is connected to the output end of the conveyor belt 10. It includes a feeding box 20 and a photoelectric counter 30. The feeding box 20 is provided with a feeding cylinder 21, and the photoelectric counter 30 is installed inside the feeding cylinder 21. The feeding cylinder 21 is connected to the output end of the conveyor belt 10. The lower end of the feeding box 20 is provided with two retractable discharge cylinders 22. The feeding box 20 is equipped with a feeding switching mechanism 40. The photoelectric counter 30 is electrically connected to the feeding switching mechanism 40. The feeding switching mechanism 40 can switch between the feeding cylinder 21 and one of the two discharge cylinders 22. Each discharge cylinder 22 is provided with a damping roller plate 23.

[0027] Specifically, the photoelectric counter 30 controls the material switching mechanism 40 using conventional technology. The system schemes used by both can be referenced in CN201210130420.2 - Automatic Counting and Packing Machine with Photoelectric Counter. The photoelectric counter 30 can adopt the technical solution in patent CN201220315484.5 - Photoelectric Counter. The working principle of both can be based on patent CN201910119232.1 - A Method and Device for Determining the Output Speed ​​of a Driver Using a Photoelectric Encoder, which will not be detailed here. Furthermore, the discharge cylinder 22 is designed to be telescopic, and can be either a corrugated pipe design or a telescopic cylinder structure. If a telescopic cylinder structure is used, it can be driven by a telescopic cylinder or manually operated. In some embodiments, the discharge cylinder 22 can also be fitted with flexible hoses, depending on the actual needs. In one embodiment of this application, each telescopic cylinder 22 consists of at least two interlocking cylinders, with the damping roll plate 23 provided on the sloping bottom surface of the lowest cylinder.

[0028] Furthermore, the lower end of the discharge cylinder 22 is connected to a packaging box, which is used to catch the dropped toys. The feed cylinder 21 is specifically connected to the frame at the output end of the conveyor belt 10 and can be fixed with screws. The feed cylinder 21 has a certain slope relative to the output end of the conveyor belt 10, allowing the toys to slide naturally on the feed cylinder 21 due to inertia after being fed from the conveyor belt 10. In addition, the damping drop plate 23, in this application, not only reduces the rolling speed of the toys but also acts as a buffer. When a toy falls from the feed cylinder 21 into the distribution box 20 and the discharge cylinder 22, the damping drop plate 23 can catch the falling toy.

[0029] This counting-function switching feeding device features a distribution box 20 to receive toys output from the conveyor belt 10, which also acts as a steering mechanism. A switching mechanism 40 switches the connection between the feed cylinder 21 and the two discharge cylinders 22, allowing for material drop in different directions and facilitating the transfer of full packaging boxes by workers. The discharge cylinders 22 are designed to be extendable, allowing workers to adjust their length to meet dropping needs, ensuring toys roll along the inner wall of the discharge cylinder 22 and reducing their falling speed. Furthermore, damping drop plates 23 are installed inside each discharge cylinder 22 to further reduce the toy's falling speed and protect it.

[0030] See Figures 1 to 2 In one embodiment of this application, to facilitate separate material feeding and adapt to packaging box switching, and to utilize the middle of the discharge cylinder 22 to catch the dropped toys, the two discharge cylinders 22 are designed in a herringbone shape, and the damping drop plate 23 is disposed on the inclined surface of the two discharge cylinders 22. In this application, the cross-section of the discharge cylinder 22 is rectangular, therefore the bottom surface of the discharge cylinder 22 is actually inclined, and the damping drop plate 23 is actually installed on the bottom surface of the discharge cylinder 22.

[0031] In one embodiment of this application, since the damping drop plate 23 is inclined, in order to better reduce the rolling speed of toys on the damping drop plate 23, the damping drop plate 23 is provided with several pairs of V-shaped damping strips 24 along its length. The distance between the closest ends of each pair of damping strips 24 gradually decreases along the guiding direction of the damping drop plate 23. The height of the ends of each pair of damping strips 24 that are far apart from each other is greater than the height of the ends that are close together. This arrangement can automatically center toys falling onto the damping drop plate 23, which is beneficial for reducing the falling speed.

[0032] In the above embodiment, in order to further reduce the rolling speed, elastic flaps 25 are provided on the ends of the bottom pair of damping strips 24 that are close to each other.

[0033] In the above embodiments, to prevent the toy from scattering or being damaged due to hard contact with the inner wall of the telescopic cylinder 22, protective plates 26 are provided on both sides of the damping roll plate 23, and a flexible padding layer is provided on the facing side of the two protective plates 26. The flexible padding layer can be a sponge layer or a rubber layer. Similarly, a protective padding layer is provided on the inner wall of the dispensing box 20, which can be a sponge layer or a rubber layer.

[0034] In the above embodiments, since the damping drop plate 23 is used as an intermediate transition to receive toys falling from the feed cylinder 21, the toys have a certain impact after rolling out of the feed cylinder 21. Therefore, relying solely on the material properties of the damping drop plate 23 to buffer the impact of the toys is difficult in practice and cannot guarantee that the toys will not be damaged. See also Figure 3 Therefore, in an improved embodiment of this application, a guide post 28 is provided on the back of the damping roll plate 23. The guide post 28 is movably inserted into the inclined surface of the discharge cylinder 22. A shock-absorbing spring 29 is fitted on the area between the back of the damping roll plate 23 and the inclined surface of the discharge cylinder 22. A locking nut 2a is provided on the end of the guide post 28 that protrudes from the inclined surface of the discharge cylinder 22. Through the shock-absorbing effect of the shock-absorbing spring 29, the impact caused by the toy falling can be effectively absorbed. At the same time, the tension of the shock-absorbing spring 29 can be adjusted by the locking nut 2a to adapt to the impact of toys of different weights.

[0035] In the above embodiment, to facilitate subsequent maintenance by staff, the side walls of the material distribution box 20 and the two discharge cylinders 22 are provided with openable and closable inspection doors 27. The inspection doors 27 are installed at corresponding positions on the material distribution box 20 and the two discharge cylinders 22 via hinges, and can also be closed via a snap-fit ​​structure.

[0036] See Figure 1 , Figure 3 and Figure 4 In one embodiment of this application, the material distribution and switching mechanism 40 includes a driver 41 and a swing plate 42. One end of the swing plate 42 is hinged to the area between the inlet ends of the two discharge cylinders 22. The mounting end of the driver 41 is connected to the material distribution box 20, and the driving end of the driver 41 is connected to the rotation center of the swing plate 42. The driver 41 is electrically connected to the photoelectric counter 30. The driver 41 can drive the swing plate 42 to swing to switch and block the inlet end of either discharge cylinder 22. In this application, the driver 41 is a motor, and the swing of the swing plate 42 can be achieved by rotating the motor in both directions to switch and block either of the two discharge cylinders 22.

[0037] Of course, in some improved embodiments, the driver 41 is a driving cylinder. In this case, the telescopic end of the driver 41 is hinged to the outward end of the swing plate 42, so that the swing plate 42 can also be driven to swing.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
