Abstract

This utility model discloses an automatic pastry plating device, belonging to the technical field of food processing equipment. It includes a frame and a baking tray conveying mechanism. A contour template is mounted on the frame and positioned above the baking tray conveying mechanism. The contour template has material discharge holes corresponding to the placement points on the baking tray. A dispensing conveying mechanism is located above the contour template, with multiple dispensing channels positioned directly above the material discharge holes. A synchronous pushing mechanism is located between the end of the dispensing conveying mechanism and the contour template, used to push multiple pastry blanks positioned directly above each material discharge hole into the corresponding discharge hole and allow them to fall into the baking tray.

Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to an automatic pastry plating device. Background Technology

[0002] In the processing and production of baked goods such as pastries and cookies, plating is an important step. Currently, most small and medium-sized pastry workshops use manual plating, where workers pick up the raw pastry pieces one by one from the conveyor belt or workbench and then manually and neatly place them into baking pans.

[0003] This traditional manual tray-setting method has significant drawbacks: First, it is cumbersome, labor-intensive, inefficient, and increasingly costly in terms of labor. Second, and most importantly, there is a significant time lag between the placement of the first pastry on the tray and the completion of the last. Pastries placed earlier are exposed to the workshop environment for a longer period, leading to varying degrees of surface moisture evaporation and resulting in differences in initial moisture content compared to later-placed pastries. Baking these trays with inconsistent placement times in the oven using the same process will result in variations in color, crispness, and internal texture of the finished pastries, severely impacting the quality stability and consistency of the same batch.

[0004] Therefore, there is an urgent need for an automated plating device that is simple in structure, low in cost, and can effectively ensure the synchronization of plating and improve the consistency of pastry quality. Utility Model Content

[0005] The purpose of this invention is to overcome the aforementioned technical difficulties and provide an automatic pastry plating device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic pastry plating device, including a frame and a baking tray conveying mechanism. The frame is provided with a contour template located above the baking tray conveying mechanism. The contour template has material discharge holes, which are set corresponding to the placement points on the baking tray. Above the contour template is a material distribution conveying mechanism with multiple material distribution channels located directly above the material discharge holes. Between the end of the material distribution conveying mechanism and the contour template, there is a synchronous pushing mechanism for pushing multiple pastry blanks located directly above each material discharge hole into the corresponding material discharge hole and causing them to fall into the baking tray.

[0007] Furthermore, the material distribution and conveying mechanism also includes a vibrating hopper, the outlet of which is connected to the material distribution channel. The number and arrangement of the material distribution channels are consistent with the number and arrangement of the single-row material dropping through holes on the template. The end outlet of each material distribution channel is aligned directly above the material dropping through hole.

[0008] Furthermore, the material distribution channel is a plurality of conveyor belts arranged in parallel, or a plurality of guide chutes arranged in parallel.

[0009] Furthermore, the synchronous pushing mechanism includes a push plate arranged laterally in front of the end of the material distribution channel and a first driving device that drives the push plate to reciprocate linearly along the conveying direction of the material distribution channel, the length of which covers the material distribution channel.

[0010] Furthermore, the baking tray conveying mechanism is a belt conveyor or a chain conveyor, and is equipped with a second drive device for driving the baking tray to move intermittently in steps.

[0011] Furthermore, the baking tray conveying mechanism is equipped with a limiting block for positioning the baking tray placed on it.

[0012] Furthermore, the contour template is mounted on the frame via a height adjustment device, which adjusts the distance between the contour template and the upper surface of the baking tray.

[0013] Furthermore, the contour template is a quick-release and replaceable installation, and the shape of the material discharge holes on it is adapted to the shape of the pastry embryo to be placed.

[0014] Furthermore, the parts of the device that primarily come into contact with the pastries are made of food-grade stainless steel.

[0015] The automatic pastry plating device provided by this utility model has the following beneficial effects: This invention fundamentally solves the core problem of uneven moisture loss and significant differences in taste caused by manually placing pastries one by one in the same baking pan, through the synergistic effect of the material distribution channel and the "spatial pre-alignment" of the contour template and the "time-forced uniformity" of the synchronous pushing mechanism, thus significantly improving the consistency of product quality. At the same time, through the quick-change contour template design, it has excellent flexible production capabilities, which can quickly adapt to the production needs of multiple varieties and small batches, resulting in significant comprehensive benefits.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] like Figure 1-3 The present invention provides an automatic pastry tray setting device, comprising a frame 1, a baking tray conveying mechanism 2, a contour template 3, a material dispensing conveying mechanism 5, and a synchronous pushing mechanism 6. The frame 1 adopts a rigid welded frame structure, providing a stable installation foundation for each functional module and ensuring that the relative positional accuracy between the material dispensing channel 51 and the contour template 3 remains unchanged when the vibrating hopper 52 is working. This is the fundamental guarantee for achieving subsequent precise coordinated actions. A baking tray conveying mechanism 2 is installed at the bottom of the frame 1. This mechanism is a belt conveyor or chain conveyor, and it is equipped with an "L"-shaped limiting block (not shown in the figure) composed of vertical and horizontal stops, used for precise positioning of the baking trays placed on it in the X and Y directions. The baking tray conveying mechanism 2 is equipped with a second drive device 8. The second drive device 8 uses a three-phase asynchronous motor with a reducer and is equipped with a frequency converter. The device is controlled by the programmable logic controller (PLC) of the equipment to drive the baking tray to perform intermittent stepping movement. Its movement rhythm is strictly linked with the "material distribution-pushing" cycle described later. Each time a synchronous pushing is completed, the baking tray moves one row of distance, thereby realizing the intermittent stepping movement of the baking tray.

[0022] The frame 1 is equipped with a contour template 3, which is located above the baking tray conveying mechanism 2. The contour template 3 has matrix-arranged material discharge holes 4, the layout of which corresponds one-to-one with the placement points on the baking tray. The contour template 3 is installed on the frame 1 through a height adjustment device 7. The height adjustment device 7 can adjust the distance between the contour template 3 and the upper surface of the baking tray. This distance is usually adjusted to be slightly larger than the thickness of the pastry dough to accommodate pastries of different thicknesses and avoid squeezing or bumping during the conveying process. In addition, the contour template 3 is a quick-release and replaceable installation, and the shape of the material discharge holes 4 on it is adapted to the shape of the pastry dough to be placed, so that the equipment can quickly adapt to the production needs of different products.

[0023] Above the contour template 3 is a material distribution and conveying mechanism 5, which includes a vibrating hopper 52 and multiple material distribution channels 51, located directly above the material discharge holes 4. An electromagnetic vibrator is installed at the bottom of the vibrating hopper 52, and its outlet is connected to the inlet of each material distribution channel 51, used to evenly distribute the pastry dough into each material distribution channel 51. The number and arrangement of the material distribution channels 51 are strictly consistent with the number and arrangement of the single row of material discharge holes 4 on the contour template 3, ensuring that the end outlet of each material distribution channel 51 is precisely aligned with the top of a material discharge hole 4, thereby achieving "spatial pre-alignment" of the pastry position. In this embodiment, the material distribution channels 51 are five parallel small synchronous belt conveying units, each driven by an independent micro gear motor, whose start and stop are controlled by a PLC. At the end of each material distribution channel 51, an optical fiber sensor (not shown in the figure) is installed to detect whether the pastry has reached its position.

[0024] The end of the material conveying mechanism 5 is provided with a synchronous pushing mechanism 6 between it and the contour template 3. This mechanism pushes multiple pastry blanks located directly above each discharge hole 4 into the corresponding discharge holes 4 and causes them to fall into the baking pan. The synchronous pushing mechanism 6 includes a push plate 61 horizontally positioned in front of the end of the material distribution channel 51 and a first driving device 62 that drives the push plate 61 to reciprocate linearly along the conveying direction of the material distribution channel 51. The push plate 61 is made of food-grade PP board, and its length covers all material distribution channels 51. In this embodiment, the first driving device 62 is a cylinder, controlled by a PLC through a solenoid valve. When all the pastries at the end of the material distribution channels 51 are in place, the cylinder drives the push plate 61 to simultaneously contact and push the entire row of pastry blanks, forcing them to be pushed through the discharge holes 4 of the contour template 3 in the same motion posture, thereby achieving synchronous falling with "forced uniformity". During this process, the hole wall of the contour template 3 guides and constrains the falling pastries, ensuring that they are neatly arranged.

[0025] The workflow for this application is as follows: 1. Preparation stage: The operator places the empty baking tray into the starting end of the conveyor line. After the equipment is started, it is conveyed to the tray placement station and precisely positioned by the limit block. The vibrating hopper 52 and the material distribution channel 51 are started.

[0026] 2. Distributing and positioning stage: The pastry dough is evenly distributed to each distribution channel 51 by the vibrating hopper 52 and conveyed forward; when the fiber optic sensors at the end of each channel detect that the pastry has arrived, the PLC controls the distribution channel 51 to stop, and the pastry is stationary directly above the discharge hole 4.

[0027] 3. Synchronous pushing and falling stage: After the PLC confirms all signals, it controls the cylinder to drive the push plate 61 to push the entire row of pastries through the feeding hole 4, and the pastries fall into the first row of the baking tray.

[0028] 4. Reset and stepping stage: After the cylinder retracts, the PLC controls the baking tray conveyor 2 to move one row distance in a step, so that the next row of empty spaces moves directly below the material drop hole 4.

[0029] 5. Cycling and Pan Changing Phase: Repeat steps 2-4 until the baking pan is full. After a full pan is output, a new empty pan is sent in, and the cycle begins.

[0030] In the equipment described in this application, all components that come into contact with the raw pastry dough, such as the vibrating hopper 52, the dispensing channel 51, the pusher plate 61, and the contour template 3, must be made of food-grade stainless steel or other materials that meet hygiene standards.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
