Description

Technical Field

[0001] This utility model particularly relates to an automatic feeding machine for ultra-thin products. Background Technology

[0002] In the production of cookies or potato chips, stacked cookies or chips need to be separated individually for subsequent processing steps such as drying and filling. Existing sorting machines typically include a frame with a material transfer device on it, and feeding and unloading channels on both sides of the frame. The function of the material transfer device is to transfer the stacked material in the feeding channel to the unloading channel one by one, which is achieved by extending into the feeding channel to pick up the cookies or potato chips one by one.

[0003] However, in actual production, as the transfer device continuously picks up and transfers materials, the horizontal height of the top surface of the stacked cookies or potato chips constantly changes. The existing transfer device has a fixed position extending into the feeding channel, which means it cannot automatically adapt to changes in the height of the material's top surface. Therefore, to ensure the transfer device can successfully pick up the first cookie or potato chip from top to bottom, operators need to continuously manually adjust the position of the stacked cookies or potato chips so that their height is suitable for the transfer device.

[0004] This manual adjustment method presents several problems: First, operators need to perform continuous sorting work, which is physically demanding and prone to fatigue, thus affecting work efficiency and product quality stability. Second, for the increasing number of ultra-thin biscuits and potato chips on the market, which are thinner and more fragile, existing automated equipment is insufficient to meet their sorting needs, requiring almost entirely manual handling. This not only significantly increases labor costs but also easily leads to higher scrap rates and reduced production efficiency due to the instability of manual operation. Furthermore, frequent manual handling poses a risk of product contamination, potentially threatening food safety and hygiene standards. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic feeding machine for ultra-thin products.

[0006] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0007] An automatic feeding machine for ultra-thin products includes a frame, on which a material transfer device is installed. A conveying mechanism for stacking and conveying multiple materials is provided on one side of the frame. The conveying mechanism defines an operating station into which the material transfer device extends. A detection device is provided on the frame. When the detection device detects that there is no material at the operating station, it sends an electrical signal to the conveying mechanism, which then moves to move the material into the operating station.

[0008] Preferably, the conveying mechanism includes a feeding channel mounted on a frame, a chain conveyor mounted in the feeding channel, a limit bar connected to the chain conveyor, and multiple baffles spaced apart on the limit bar. Adjacent baffles and the limit bar together form a storage trough for stacking multiple materials. The chain conveyor drives the limit bar to move, thereby moving the materials in the storage trough into the operating station.

[0009] Preferably, the feeding channel includes an arc-shaped section and a horizontal section, the upper end of the arc-shaped section is located below the material transfer device, and the lower end of the arc-shaped section is connected to the horizontal section.

[0010] Preferably, a feeding channel is connected to the frame, and the feeding channel is inclined downward from the frame.

[0011] Preferably, a guide plate is provided in the feeding channel, and the guide plate and the feeding channel together form a guide trough, the cross-section of which is triangular.

[0012] Preferably, the material transfer device includes a connecting pipe, one end of which is connected to a vacuum pump and the other end to a silicone suction nozzle. A mounting frame is connected to the silicone suction nozzle, and a swing mechanism is provided on the mounting frame. A rotary motor is connected to the swing mechanism, and the rotary motor drives the mounting frame to swing back and forth through the swing mechanism.

[0013] Preferably, the swing mechanism includes a swing rod connected to a rotary motor, a movable plate connected to the swing rod, the movable plate being slidably mounted on a frame, a rack being provided on the movable plate, a gear meshing with the rack being provided on the frame, a swing arm being connected to the gear, and the swing arm being connected to a mounting frame.

[0014] The beneficial effects of this utility model are:

[0015] To reduce operational complexity, this application incorporates a material transfer device on the frame. A conveying mechanism for stacking and transporting multiple materials is located on one side of the frame. This conveying mechanism defines an operating station into which the material transfer device extends. A detection device is mounted on the frame. When the detection device detects no material at the operating station, it sends an electrical signal to the conveying mechanism, causing the mechanism to move and move the material into the operating station. This design allows for timely material delivery to the operating station, ensuring continuous material transfer. Throughout the process, frequent manual handling and material pushing are unnecessary, reducing material handling time and labor intensity. Reduced manual operation lowers the risk of material damage due to improper handling, contributing to lower scrap rates and improving product quality stability and consistency. It also reduces reliance on manual labor, especially when handling ultra-thin, fragile, and irregularly shaped products, avoiding high scrap rates and low efficiency caused by unstable manual operation. This high flexibility reduces labor costs in the production process. Furthermore, it minimizes direct contact between workers and materials, reducing the risk of product contamination.

[0026] An automatic feeding machine for ultra-thin products, referring to Figures 1-4 The system includes a frame 1, on which a material transfer device is provided. A conveying mechanism for stacking and conveying multiple materials 2 is provided on one side of the frame 1. The conveying mechanism defines an operating station 3 into which the material transfer device extends. A detection device is provided on the frame 1. When the detection device detects that there is no material 2 in the operating station 3, the detection device sends an electrical signal to the conveying mechanism, and the conveying mechanism moves to move the material 2 into the operating station 3.

[0027] Furthermore, the conveying mechanism includes a feeding channel 41 set on the frame 1, a chain conveyor is set in the feeding channel 41, a limit bar 42 is connected to the chain conveyor, and multiple baffles 43 are spaced apart on the limit bar 42. Adjacent baffles 43 and limit bars 42 together form a storage trough for stacking multiple materials 2. The chain conveyor drives the limit bar 42 to move, so as to move the materials 2 in the storage trough into the operating station 3.

[0028] Furthermore, the feeding channel 41 includes an arc-shaped section 411 and a horizontal section 412. The upper end of the arc-shaped section 411 is located below the material transfer device, and the lower end of the arc-shaped section 411 is connected to the horizontal section 412.

[0029] Furthermore, a feeding channel 5 is connected to the frame 1, and the feeding channel 5 is inclined downward from the frame 1.

[0030] Furthermore, a guide plate 51 is provided inside the feeding channel 5. The guide plate 51 and the feeding channel 5 together form a guide trough, and the cross-section of the guide trough is triangular.

[0031] Furthermore, the material transfer device includes a connecting pipe 61, one end of which is connected to a vacuum pump 62, and the other end is connected to a silicone suction nozzle 63. A mounting frame 64 is connected to the silicone suction nozzle 63, and a swing mechanism is provided on the mounting frame 64. A rotary motor 65 is connected to the swing mechanism, and the rotary motor 65 drives the mounting frame 64 to swing back and forth through the swing mechanism.

[0032] Furthermore, the swing mechanism includes a swing rod 71 connected to a rotary motor 65, a movable plate 72 connected to the swing rod 71, the movable plate 72 being slidably mounted on the frame 1, a rack 721 being provided on the movable plate 72, a gear 722 being provided on the frame 1 and meshing with the rack 721, a swing arm 723 being connected to the gear 722, and the swing arm 723 being connected to the mounting bracket 64.

[0033] The working principle of this utility model is as follows:

[0034] Material 2, taking cookies as an example, involves placing stacked cookies onto a conveyor mechanism, which then moves the stacked cookies upwards. Figure 1As shown, cookies are stacked sequentially from top to bottom. When the topmost cookie is moved into operating station 3, the transfer device adsorbs the topmost single cookie in the stack and then moves it into the feeding channel 5 (moving into means that the transfer device moves the adsorbed cookie to the top of the feeding channel, then releases the adsorption, and the cookie falls into the feeding channel 5 under gravity). As an embodiment 1, this application sets the feeding channel 41 as an arc-shaped section 411 and a horizontal section 412. The lower end of the arc-shaped section 411 is connected to the horizontal section 412, and the upper end of the arc-shaped section 411 is located below the transfer device. The position of the topmost end of the arc-shaped section 411 is defined as operating station 3. The detection device on the frame 1 is used to detect whether there are cookies on operating station 3. When there are cookies, the transfer device extends into operating station 3 to adsorb cookies one by one, and then moves the cookie out of operating station 3 and into the feeding channel 5. When the detection device detects that there are no cookies on operating station 3, it sends an electrical signal to the conveying mechanism, which then moves the cookies upwards to operating station 3. Thus, each time a cookie is removed by the transfer device, the conveying mechanism, under the action of the detection device, promptly pushes the cookie to operating station 3, ensuring continuous cookie transfer. Throughout the process, manual pushing of cookies into operating station 3 is unnecessary, reducing labor intensity. In embodiment 1, the conveying mechanism can be a combination of a chain conveyor and a limiting bar 42. Multiple baffles 43 are spaced apart on the limiting bar 42, and adjacent baffles 43 and the limiting bar 42 together form a storage trough. This storage trough is used to stack multiple cookies. When the chain conveyor starts, it can activate the limiting bar 42, thereby moving the storage trough and transferring the cookies within to operating station 3.

[0035] Based on the above technical solution, the material transfer device mentioned in this application includes a connecting pipe 61, one end of which is connected to a vacuum pump 62, and the other end is connected to a silicone suction nozzle 63. A mounting frame 64 is connected to the silicone suction nozzle 63, and a swing mechanism is connected to the mounting frame 64. As shown in the figure, the swing mechanism drives the mounting frame 64 to move, so that the silicone suction nozzle 63 on the mounting frame 64 extends into the operating station 3 to adsorb the biscuit in the operating station 3. Then, the swing mechanism moves the biscuit to the designated position, releases the silicone suction nozzle 63 from the biscuit, and the biscuit falls into the feeding channel 5. The swing mechanism depends primarily on the desired position of the biscuit, as shown in the figure. For example, to move the biscuit from the feeding channel 41 of the frame 1 into the unloading channel 5, a swing arm 723 can be installed on the frame 1. Mounting brackets 64 are connected to the swing arm 723. A gear 722 connected to the swing arm 723 is connected to the frame 1. The gear 722 meshes with a rack 721. A moving plate 72 is connected to the rack 721. A swing rod 71 is connected to the moving plate 72. A rotary motor 65 is connected to the swing rod 71. When the rotary motor 65 drives the swing... When the lever 71 swings, the swing lever 71 drives the moving plate 72 to swing back and forth. The moving plate 72 is slidably mounted on the frame 1. Therefore, the rack 721 on the moving plate 72 meshes with the gear 722, thereby driving the swing arm 723 to rotate (the rotation range of the swing arm 723 is 0-180 degrees). The mounting frame 64 is also rotatably mounted on the swing arm 723, so the mounting frame 64 will swing back and forth. The silicone suction nozzle 63 is also mounted on the mounting frame 64, so the silicone suction nozzle 63 can adsorb the biscuits in the operating station 3 and transfer them into the feeding channel 5.

[0036] Based on the above technical solution, this application provides a guide plate 51 within the feeding channel 5. The guide plate 51 and the feeding channel 5 together form a guide trough. The cross-section of the guide trough is triangular, and the guide trough guides the movement of the biscuit. This design prevents the biscuit from getting stuck in the feeding channel 5. The feeding channel 5 of this application is inclined downwards from the frame 1. When the biscuit is released from the adsorption connection with the silicone nozzle 63, the biscuit falls into the feeding channel 5 and slides to the designated position under the action of gravity. Figure 4 This is a schematic diagram of the movement of the biscuit within the feeding channel 5.

[0037] In the above technical solution, the detection device can be implemented using a photoelectric sensor. The materials in this application are not limited to biscuits, but also include chip products such as potato chips.

[0038] To reduce operational complexity, this application includes a material transfer device on the frame 1. A conveying mechanism for stacking and transferring multiple materials 2 is located on one side of the frame 1. This conveying mechanism defines an operating station 3 into which the material transfer device extends. A detection device is installed on the frame 1. When the detection device detects no material 2 at the operating station 3, it sends an electrical signal to the conveying mechanism, causing the mechanism to move and move the material 2 into the operating station 3. This allows for timely delivery of materials to the operating station, ensuring continuous material transfer. Throughout the process, there is no need for frequent manual handling and pushing of materials into the operating station, reducing the time spent on material handling and lowering labor intensity. Reduced manual operation lowers the risk of material damage due to improper handling, helping to reduce scrap rates and improve product quality stability and consistency. It also reduces reliance on manual labor, especially when handling ultra-thin, fragile, and irregularly shaped products (ultra-thin biscuits can be as thin as 1.2cm-1.7cm), avoiding the high scrap rates and low efficiency caused by unstable manual operation. This high flexibility reduces labor costs in the production process. Furthermore, it reduces direct contact between workers and materials, lowering the risk of product contamination.

[0039] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
