Description

Technical Field

[0001] This utility model relates to the field of automated packaging, specifically to a feeder. Background Technology

[0002] The applicant previously filed a Chinese utility model patent with application number "2025204544728" entitled "A Multi-Piece Packaging Equipment," which described a device where a discharge track is connected to the upper outlet of a vibratory feeder. Above the discharge track are a first stop assembly and a second stop assembly. The first stop assembly includes a pressing cylinder located above the discharge track and a pressing rod driven by the pressing cylinder to descend. The second stop assembly includes a stop cylinder located at the outlet of the discharge track and a stop rod driven by the stop cylinder to extend and retract. The cooperation of the first and second stop assemblies ensures that the vibratory feeder outputs only one product at a time. However, in actual use, the applicant found that the pressing rod often applies excessive pressure to the product during the pressing action, resulting in product damage. Utility Model Content

[0003] Based on this, and in response to the above problems, this utility model provides a feeder.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A feeder includes a chain conveyor and multiple vibratory feeders located on both sides of the chain conveyor. Multiple receiving boxes for receiving products output from the vibratory feeders are spaced apart on the closed chain of the chain conveyor. Each vibratory feeder has an outlet connected to a discharge track, with the outlets of the discharge tracks facing the chain. Above the discharge tracks are mutually cooperating first and second stop assemblies. The first stop assembly includes a pressing cylinder located above the discharge track and a pressing rod driven downwards by the pressing cylinder. The second stop assembly includes a stop cylinder horizontally positioned at the outlet of the discharge track and a stop rod driven to extend and retract by the stop cylinder. When the stop rod extends to stop the product at the foremost position, the pressing rod is driven to press down the next product. Both the stop rod and the pressing rod are fitted with rubber sleeves.

[0006] By adopting the above technical solution, rubber sleeves are fitted on both the stop bar and the pressure bar, which can play a buffering role and protect the product from being crushed.

[0007] In a specific embodiment of this utility model, a controller is also included, and a counter is provided above the discharge track. The stop cylinder, the pressing cylinder, and the counter are all electrically connected to the controller.

[0008] In a specific embodiment of this utility model, it also includes two cabinets spaced apart, a chain conveyor device installed between the two cabinets, and eight vibratory feeders, with four vibratory feeders installed on the top surface of each of the two cabinets.

[0009] In a specific embodiment of this utility model: a guide component is provided below the outlet of the discharge track of the vibratory feeder to guide the product smoothly into the material container.

[0010] In a specific embodiment of this utility model: the guiding component includes a support plate and a tube. The support plate is placed above the stopping position on the chain conveyor. The support plate has an inclined insertion port. One end of the tube is inserted into the insertion port of the support plate, and the other end is connected to the outlet of the discharge track through a connector.

[0011] In summary, this invention ensures that only one product is output from each vibratory feeder at a time by placing different types of products in different vibratory feeders and by setting a first stop assembly and a second stop assembly that cooperate with each other above the discharge track of each vibratory feeder. Rubber sleeves are fitted onto the pressing rod of the first stop assembly and the stop rod of the second stop assembly to provide cushioning and protect the product from being crushed. The drive collection box sequentially passes through each vibratory feeder to receive and collect the products output by that feeder, thus ensuring that no product of any type is missed in a set.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 As shown, this utility model is a feeder, including a chain conveyor 10 and multiple vibratory feeders 20 located on both sides of the chain conveyor 10. Multiple material collection boxes 12 are spaced apart on the chain of the chain conveyor 10. The material collection boxes 12 are used to receive the products output from the vibratory feeders 20.

[0022] Combination Figure 2 As shown, each vibratory feeder 20 includes a vibratory base 21 and a vibratory feeder body 22 mounted on the vibratory base 21. The inner wall of the vibratory feeder body 22 has a spirally rising inner track, and a discharge track 23 is connected to the upper outlet of the inner track. A first stop assembly 24 and a second stop assembly 25 are provided on the discharge track, cooperating with each other. In this embodiment, the first stop assembly 24 includes a pressing cylinder 241 located above the discharge track 23 and a pressing rod 242 driven downward by the pressing cylinder 241. The second stop assembly 25 includes a stop cylinder 251 horizontally positioned at the outlet of the discharge track and a stop rod 252 driven to extend and retract by the stop cylinder 251. Thus, when the stop cylinder 251 drives the stop rod 252 to extend, the stop rod 252 can block the product reaching the discharge track. When the pressing cylinder 241 drives the pressing rod 242 to descend, it can press down the product below the pressing rod 242. When the stop bar is driven to extend and block the product at the foremost position of the discharge track outlet, the pressing cylinder 241 drives the pressing rod to press down the next product.

[0023] In this embodiment, both the pressure rod 242 and the stop rod 252 are fitted with food-grade rubber sleeves. These sleeves provide cushioning and prevent the product from being crushed.

[0024] This also includes a controller (not shown in the figure). A counter 13 is also installed above the discharge track. The stop cylinder 251, the pressing cylinder 241, and the counter 13 are all electrically connected to the controller.

[0025] It also includes two cabinets 14 spaced apart. There are eight vibratory feeders, with four vibratory feeders 20 mounted on the top surface of each of the two cabinets 14. A first stop assembly 24, a second stop assembly 25, and a counter 13 are mounted on the cabinets via brackets 27. A chain conveyor 10 is installed between the two cabinets. In this embodiment, the chain conveyor is a motor-driven sprocket that drives a closed chain to rotate, thus moving the material container. The chain-driven material container has a stopping position when it moves under each vibratory feeder. The chain rotates intermittently driven by the motor, causing the material container to stop at each stopping position to ensure that the material container can receive the product output from the vibratory feeder. Here, the extension and retraction time of the stop cylinder-driven stop rod is matched to the chain running speed. The chain conveyor is prior art and will not be described in detail here.

[0026] like Figure 2 As shown, a guide assembly 15 is provided below the outlet of the vibratory feeder's discharge track to guide the product smoothly into the collection box. In this embodiment, the guide assembly 15 includes a support plate 151 and a tube 152. The support plate 151 is placed above the corresponding stopping position and has an inclined insertion port 154. One end of the tube 152 is inserted into the insertion port 154 of the support plate 151, and the other end is connected to the outlet of the discharge track via a connector 153. In use, each support plate 151 is placed on the two fixed plates 11 of the chain conveyor above the corresponding stopping position. One end of the tube 152 is connected to the outlet end of the vibratory feeder 20's discharge track via a connector 153, and the other end is inserted into the insertion port 154 of the support plate 151. In this way, the product falls from the outlet of the discharge track, passes through the tube, and falls into the arriving collection box 12.

[0027] To clearly illustrate this invention, a four-pack containing four different colored products will be used as an example. Eight vibrating discs, labeled 20a to 20h, are used. Vibrating disc 20a holds the yellow product, vibrating disc 20b holds the white product, vibrating disc 20c holds the red product, and vibrating disc 20d holds the blue product. Before the dispensing process begins, the products in these four vibrating discs (20a, 20b, 20c, and 20d) move sequentially along the inner track towards the outlet track by the vibration of the vibrating base. Figure 3 As shown, taking the vibratory plate 20a as an example, the yellow products will move one by one along the inner track towards the outlet of the discharge track under the vibration of the vibratory plate. The stop cylinder 251 drives the stop rod 252 to extend and intercept the yellow product at the front. This yellow product is the current product A. The pressing cylinder 241 will drive the pressing rod 242 to descend and press down the next product B that follows the current product A, so as to ensure that product B will not fall prematurely due to vibration.

[0028] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, when material needs to be separated, the stop cylinder 251 drives the stop rod 252 to retract, allowing the current product A to fall freely and enter the receiving box 12 via the guide assembly. Subsequently, the stop cylinder 251 drives the stop rod 252 to extend, blocking the outlet of the discharge track, while the pressing cylinder 241 drives the pressing rod 242 to rise, releasing the pressed product B. Product B continues to move forward under the continuous vibration of the vibrating chassis until it is intercepted by the stop rod 252. The pressing cylinder 241 then drives the pressing rod 242 to descend, pressing down the next product C following product B. This process is then repeated continuously. Thus, through the cooperation of the first and second stop components, the vibrating plate 20a outputs only one yellow product at a time. After the material container receives a yellow product from vibratory feeder 20a, the chain drives it forward to receive a white product from vibratory feeder 20b, a red product from vibratory feeder 20c, and a blue product from vibratory feeder 20d. Finally, the material container collects all the products for one package. Then, it is conveyed to the next process step.

[0029] In summary, this invention ensures that different types of products are placed in different vibratory feeders, and that a first stop assembly and a second stop assembly are installed above the discharge track of each vibratory feeder to ensure that only one product is output from each vibratory feeder at a time. The drive cassette sequentially passes through each vibratory feeder to receive all the required products, thus ensuring that no product is missed. The rubber sleeves on the stop rods and pressure rods provide cushioning, protecting the products from damage.

[0030] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
