Description

Technical Field

[0001] This application relates to the field of automatic material dispensing technology, and in particular to a conveyor and automatic material dispensing equipment. Background Technology

[0002] When pre-packaging materials such as candy and pharmaceuticals, it is typically necessary to accurately weigh the materials according to a predetermined amount, divide them into multiple portions, and then transport these portions to a packaging machine via a conveyor belt. The packaging machine then fills each portion into a specific bag. However, most existing conveyor belts only separate adjacent portions using dividers. This type of conveyor belt makes it difficult to precisely control the quantity of each portion, making flexible quantity settings impractical. Furthermore, when the conveyor belt changes direction, materials can easily slip off, which not only reduces the accuracy of material distribution but also results in material waste. Utility Model Content

[0003] This application discloses a conveyor and an automatic material dispensing device to solve the problem that existing transmission belts cannot accurately control the amount of each material when conveying multiple materials, which easily leads to material waste.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] In a first aspect, this application provides a conveyor, which includes a conveying device and a tray. The conveying device includes a conveying surface, and a plurality of trays are spaced apart under the conveying surface. The trays are used to carry a preset amount of material. The conveyor includes a feeding area located at the end of the conveyor along the running direction of the conveying surface. The feeding area is provided with a first monitoring device, which is used to monitor at least the amount of material in the trays located in the feeding area.

[0006] The conveyor device features multiple trays on its conveyor surface, each capable of holding a preset amount of material. These trays prevent material from slipping off the conveyor belt, thus improving the accuracy of material handling. Furthermore, the unloading area of ​​the conveyor is equipped with a first monitoring device. This device monitors the amount of material in the trays located in the unloading area, allowing non-compliant trays to be rejected and compliant trays to be filled with the predetermined amount of material into packaging bags, thereby improving the accuracy of material packaging.

[0007] Furthermore, the first monitoring device is selected from at least one of a visual inspection system and a weight sensor.

[0008] Furthermore, the pallet includes a bottom plate and side plates arranged circumferentially around the bottom plate, the bottom plate and side plates forming a boat-shaped cavity.

[0009] Furthermore, the surface of the bottom plate facing away from the conveyor surface is flat, and the side plates form an angle with the bottom plate toward the boat-shaped chamber.

[0010] Furthermore, the conveyor also includes a feeding area, which is located at the front end of the conveyor along the running direction of the conveying surface. The feeding area is equipped with a second monitoring device, which is used to monitor at least the status of the material in the tray located in the feeding area.

[0011] Furthermore, the conveying device also includes a frame supporting the conveying surface. The frame includes a first frame, a second frame, and a third frame. The first frame is located in the loading area, the second frame is located in the unloading area, and the third frame is located between the first frame and the second frame. The conveying surfaces corresponding to the first frame and the second frame are both planar.

[0012] Furthermore, the second frame is higher than the first frame; and / or, the conveyor also includes a servo motor for controlling the running speed of the conveyor surface.

[0013] Furthermore, the conveyor also includes a transparent protective shell that forms a receiving cavity, within which the conveying surface and the tray are located.

[0014] Secondly, this application provides an automatic material dispensing device, which includes a front-end device and a conveyor as described in the first aspect. The front-end device is located at the front end of the conveyor and is used to place a preset amount of material into a tray.

[0015] Because of the conveyor included in this application, when the pallet is in the loading area, the front-end device places the material in the pallet so that the pallet carries a preset amount of material. During the conveying process, the material is placed directly on the conveying surface, which can prevent the material from slipping and thus avoid material waste. Moreover, when the pallet arrives at the unloading area, the first monitoring device monitors the amount of material in the pallet, rejects pallets that do not meet the standard, and packs the material in the pallets that meet the standard into specific packaging bags, so that each packaging bag is filled with a preset amount of material, thereby improving the accuracy of material packaging.

[0016] Furthermore, the automatic material dispensing equipment also includes a rear-end device. Along the running direction of the conveyor surface, the rear-end device is located at the rear end of the conveyor and is used to put a preset amount of material into a packaging bag.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Existing quantitative packaging machines can accurately dispense materials, such as candy and medicine, into predetermined quantities and pack them into bags of specific shapes and sizes. However, existing quantitative packaging machines typically have difficulty flexibly setting the quantity of each material or changing the shape and size of the packaging bags. Therefore, existing quantitative packaging machines struggle to meet consumers' personalized needs.

[0030] In view of this, embodiments of this application provide a conveyor. Figure 1 This is a schematic diagram of the structure of a conveyor according to one embodiment of this application. Figure 2This is a schematic diagram of the structure of a conveyor according to one embodiment of this application. Figure 3 This is a schematic diagram of the structure of a conveyor according to one embodiment of this application. Figure 4 This is a schematic diagram of the structure of a transmitter according to one embodiment of this application. Please refer to it as well. Figures 1 to 4 The conveyor 10 includes a conveying device 100 and a tray 200. The conveying device 100 includes a conveying surface 01, and a plurality of trays 200 are spaced apart under the conveying surface 01. The trays 200 are used to carry a preset amount of material. The conveyor 10 includes a feeding area 04. Along the running direction of the conveying surface 01, the feeding area 04 is located at the end of the conveyor 10. The feeding area 04 is provided with a first monitoring device (not shown in the figure). The first monitoring device is used to monitor at least the amount of material in the trays 200 located in the feeding area 04.

[0031] The first monitoring device includes, but is not limited to, a weight sensor and a vision inspection system. This device can detect the weight of the materials in the pallet 200, rejecting materials and corresponding pallets 200 that do not meet the weight requirements, and only processing pallets 200 whose material weight meets the preset requirements. Furthermore, when the first monitoring device is a vision inspection system, it can also detect the type, volume, color, or shape of the materials in the pallet 200 to ensure that the materials in the pallet 200 meet specific requirements.

[0032] Therefore, the conveyor 10 in this application can monitor the quantity, type, color, or shape of the materials in each tray 200 to ensure they meet preset requirements. When packaging materials, the conveyor 10 directly transports the materials divided into several portions through multiple corresponding trays 200 to the unloading area 04. The first monitoring device in the unloading area 04 monitors the materials in each tray 200 and removes materials that do not meet the requirements, thereby achieving accurate and convenient packaging. Compared to existing conveyor belts, the conveyor 10 significantly improves the efficiency of material packaging, and placing each portion of material within a tray 200 reduces or prevents material slippage, minimizing waste.

[0033] Reference Figures 1 to 3 The conveyor 10 also includes a loading area 02 located at the front end of the conveyor 10 along the running direction of the conveying surface 01. The pallet 200 moves along the conveying surface 01 from the loading area 02 to the unloading area 04. The loading area 02 is equipped with a second monitoring device (not shown in the figure). The second monitoring device is used to monitor the state of the material in the pallet 200 located in the loading area 02. The state of the material includes, but is not limited to, the quantity, color, volume, and shape of the material. Based on the detection results of the second monitoring device, materials that do not meet the requirements are removed so that the material in the pallet 200 meets the preset requirements.

[0034] The second monitoring device includes at least one of a weight sensor and a visual inspection system.

[0035] In some optional embodiments, the conveyor 10 further includes a positioning element (not shown) located in the unloading area 04. When the positioning element detects that the tray 200 has reached a preset position, the tray 200 stops moving to unload the material from the tray 200. The positioning element may be a photoelectric sensor.

[0036] Reference Figure 1 and Figure 2 The conveying device 100 also includes a frame 110 supporting the conveying surface 01. The frame 110 includes a first frame 111, a second frame 112 and a third frame 113. The first frame 111 is located in the loading area 02, the second frame 112 is located in the unloading area 04, and the third frame 113 is located between the first frame 111 and the second frame 112.

[0037] The first frame 111, the second frame 112 and the third frame 113 can be detachably connected or be a one-piece molded structure.

[0038] In some optional embodiments, the conveying surface 01 corresponding to the first frame 111 is a plane to facilitate the installation of a second monitoring device for monitoring the materials in the pallet 200.

[0039] In some optional embodiments, the conveying surface 01 corresponding to the second frame 112 is a plane, so as to facilitate the transfer of materials in the pallet 200 to subsequent processing equipment, and also to facilitate the first monitoring device to monitor the materials in the pallet 200.

[0040] In some alternative embodiments, the conveying device 100 further includes a conveyor belt or a conveyor chain. Preferably, a conveyor chain is provided on the frame 110, and multiple trays 200 are fixed to the conveyor chain and can move forward as the conveyor chain rotates. Compared to a conveyor belt, the connection between the conveyor chain and the trays 200 is more secure, such as... Figure 1 As shown, the frame 110 may include an upper surface and a lower surface. A pallet 200 containing materials is conveyed from the loading area 02 to the unloading area 04 via the upper surface of the frame 110. Then, in the unloading area 04, the materials in the pallet 200 are transferred to the processing equipment at the rear end. After unloading the materials, the pallet 200 can be conveyed from the unloading area 04 to the loading area 02 via a conveyor chain. Therefore, the pallet 200 can be recycled by rotating the conveyor chain.

[0041] It is understandable that the heights of the first frame 111 and the second frame 112 can be the same, or they can be different. For example... Figure 1As shown, the second frame 112 is higher than the first frame 111, meaning that materials are conveyed from a lower position to a higher position. Of course, the second frame 112 can also be lower than the first frame 111, depending on the actual needs.

[0042] When the heights of the first frame 111 and the second frame 112 are not equal, the conveyor 10 also includes a servo motor to control the running speed of the conveyor surface 01 in order to make the pallet 200 run more smoothly on the conveying surface 01. When the pallet 200 passes through the connection between the first frame 111 and the third frame 113, or through the connection between the second frame 112 and the third frame 113, the servo motor controls the running speed of the conveyor surface 01 to slow down, so that the pallet 200 passes through the corner smoothly and avoids the material falling off the pallet 200 due to a change in the running direction of the pallet 200.

[0043] In this application, the pallet 200 is used to carry materials, preventing adjacent materials from getting mixed up or slipping off the conveyor surface 01. The specific shape and structure of the pallet 200 can be set according to actual needs. Furthermore, the number of pallets 200 on the conveyor surface 01 and the spacing between adjacent pallets 200 can be set according to actual needs. For example, 20, 30, 50, or 100 pallets 200 can be set on the conveyor surface 01.

[0044] Figure 5 This is a schematic diagram of the structure of a tray according to one embodiment of this application, with reference to... Figure 5 The pallet 200 includes a base plate 210 and side plates 220 arranged circumferentially around the base plate 210. The base plate 210 and side plates 220 form a boat-shaped chamber 03. When materials are placed in the boat-shaped chamber 03, the pallet 200 can protect the materials and prevent them from falling or becoming contaminated.

[0045] Continue to refer to Figure 5 The surface of the base plate 210 facing away from the conveyor surface 01 is flat, and the side plate 220 forms an angle with the base plate 210 toward the boat-shaped chamber 03. The flat surface of the base plate 210 facing away from the conveyor surface 01 facilitates the monitoring of the materials in the pallet 200 by the first monitoring device or the second monitoring device.

[0046] In some optional embodiments, the angle between the side plate 220 and the bottom plate 210 toward the boat-shaped chamber 03 is greater than or equal to 90°, which facilitates the placement of materials into the tray 200 and the unloading of materials from the tray 200.

[0047] In some alternative embodiments, the conveyor 10 further includes a transparent protective shell 300 forming a receiving cavity in which the conveying surface 01 and the tray 200 are located. The transparent protective shell 300 can prevent contaminants from entering the tray 200 without affecting the observation of the materials in the tray 200.

[0048] Based on the same technical concept, this application also provides an automatic material dispensing device. Figure 6 This is a schematic diagram of the structure of an automatic material dispensing device according to an embodiment of this application. Figure 7 This is a schematic diagram of the structure of a material transfer component according to an embodiment of this application. Figure 8 This is a top view of an automatic material dispensing device according to an embodiment of this application, with reference to... Figures 6 to 8 The automatic material dispensing equipment includes a front-end device 20 and a conveyor 10 in various possible embodiments of this application. The front-end device 20 is located at the front end of the conveyor 10 and is used to place a preset amount of material in a tray 200.

[0049] Among them, the automatic material dispensing equipment can be used to dispense medicines, candies, etc. When dispensing medicines, the front-end device 20 can be a dispensing machine, which divides the medicine into multiple portions according to customer requirements. Each portion of medicine is conveyed to a tray 200 through the dispensing machine.

[0050] Reference Figure 6 The front-end device 20 includes a body 21, which has a discharge port 05. Optionally, the bottom of the discharge port 05 is higher than the conveying surface 01 of the loading area 02 of the conveyor 10.

[0051] In some optional embodiments, the automated material dispensing equipment further includes a material transfer assembly 40 disposed between the front-end device 20 and the conveyor 10. (See also...) Figure 7 The material transfer assembly 40 includes a material transfer trough 41 and a valve 42. One end of the material transfer trough 41 is connected to the discharge port 05, and the other end of the material transfer trough 41 is located above the conveying surface 01 of the feeding area 02. Optionally, the material transfer trough 41 can be a U-shaped trough or a V-shaped trough, and the specific shape and structure can be set according to actual needs.

[0052] In some alternative embodiments, valve 42 is located at the end of the feed chute 41 near the conveying surface 01. Valve 42 includes an open state and a closed state. When valve 42 is open, material can fall from feed chute 41 into tray 200; when valve 42 is closed, it can prevent material from falling further.

[0053] Continue to refer to Figure 7The material transfer assembly 40 also includes a cylinder 43, which includes a piston rod. The valve 42 includes a valve seat and a valve plate. The piston rod and the valve plate are connected and can drive the valve plate to move so that the valve plate and the valve seat contact or separate, thereby putting the valve 42 in a closed state or an open state.

[0054] In some alternative embodiments, the material transfer assembly 40 further includes a solenoid valve, which is connected to the cylinder 43 via a circuit to control the cylinder 43 to open and close the valve 42.

[0055] You can continue to refer to Figure 7 The material transfer assembly 40 also includes a proximity switch and a controller. Both the solenoid valve and the proximity switch are signal-connected to the controller. The proximity switch is located to the side front of the discharge port 05 of the front-end device 20. The proximity switch detects the opening and closing of the discharge port of the front-end device and generates an electrical signal, which is then transmitted to the controller. The controller then controls the opening and closing of the solenoid valve accordingly.

[0056] Understandably, the controller can calculate the time it takes for all the material to reach the end of the conveyor trough 41 based on the material's sliding time, and then control the solenoid valve to open and close the valve 42 accordingly. The material's sliding time is determined through extensive testing, showing the time it takes for the material to slide from the outlet of the front-end device to the valve 42.

[0057] It should be noted that if the material flows freely from the feed chute 41 into the tray 200, the time it takes for the material to reach the tray 200 will vary slightly. Since the tray 200 has a limited dwell time at the end of the feed chute 41, if the material arrives slightly earlier or later, it can easily fall out of the tray 200. Therefore, the valve 42 is designed to collect a preset amount of material so that the preset amount of material can all fall into the tray 200 together, thereby preventing material overflow.

[0058] In some alternative embodiments, the controller may be a programmable logic controller (PLC).

[0059] The structure and composition of the material transfer assembly 40 have been described in detail above. The working process of the material transfer assembly 40 is explained in detail below:

[0060] When the discharge port 05 of the front-end device 20 is opened, the material enters the conveying trough 41 from the discharge port 05 and slides down from the upstream of the conveying trough 41 to the downstream valve 42. At the same time, the proximity switch senses that the discharge port 05 is open and transmits an electrical signal to the controller. The controller calculates the sliding time of the material and controls the valve 42 to be in the open state through the solenoid valve, so that the material can enter the tray 200 through the valve 42.

[0061] Continue to refer to Figure 6 and Figure 8 The automatic material packaging equipment also includes a rear-end device 30. Along the running direction of the conveyor surface 01, the rear-end device 30 is located at the rear end of the conveyor 10. The rear-end device 30 is used to pack a preset amount of material into a packaging bag.

[0062] Depending on the process flow of the packaged materials, the back-end device 30 can be a packaging machine or other processing equipment.

[0063] For example, the back-end device 30 can be a single-row sealing bag packaging machine, which can seal a roll of film into a packaging bag of a specific shape and size, with each packaging bag containing one item of material. When the pallet 200 runs to the preset position of the unloading area 04, the material in the pallet 200 is tilted downwards, and the material falls into the hopper 31 of the packaging machine connected below the conveyor surface 01, and is then wrapped in a packaging bag.

[0064] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
