A conveying device for producing egg yolk cakes

Abstract

This utility model relates to the field of food processing equipment technology, specifically disclosing a conveying device for producing egg yolk pastries, solving the problems of low efficiency and high cost of robotic arms in loading trays. The device includes a main conveyor belt, a vertical rotating positioning turntable, a packaging tray conveyor belt, and a synchronous drive control system. Multiple workstations are set along the edge of the turntable, each with a controllable material discharge port integrated at its bottom. The main conveyor belt continuously feeds the egg yolk pastries into the uniformly rotating turntable workstations. When a workstation reaches a preset material discharge angle, the material discharge port opens instantaneously, and the egg yolk pastry falls vertically. The tray conveyor belt moves synchronously and uniformly with the turntable, allowing empty trays to dynamically receive the egg yolk pastries at the material discharge point. This solution achieves stop-and-go operation through the coordinated control of continuous rotation, parameterized triggering, and dynamic material discharge, achieving a packaging speed of 300 pieces / minute, which is 5 times more efficient than traditional robotic arms, with a product damage rate of <0.1%. It is suitable for the automated packaging of fragile pastries such as egg yolk pastries.

Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a conveying device for producing egg yolk pastries. Background Technology

[0002] In existing automated packaging production lines for egg yolk pastries, the common feeding method is as follows: the baked and cooled egg yolk pastries are placed on the main conveyor belt manually or mechanically, and the conveyor belt delivers the egg yolk pastries to the packaging station, where a robotic arm or a complex multi-degree-of-freedom sorting mechanism picks up the egg yolk pastries one by one. The following methods have significant drawbacks:

[0003] Inefficiency and long cycles of robotic arm grasping, moving, and releasing actions have become a bottleneck for the overall production line speed.

[0004] The equipment is complex and expensive, with high costs for the robotic arm and its precision control, and complex maintenance.

[0005] Product damage risk: Improper control of the gripping force of the mechanical claw can easily lead to breakage or deformation of the pastry;

[0006] Large footprint: The robotic arm requires a large operating space for its working range;

[0007] High positioning accuracy requirement: Requires extremely high positioning accuracy from the robotic arm and a high-precision vision system;

[0008] The patent CN201711137803.1, which proposes "a device for conveying boxed egg crisps," has limited applicability. It is only applicable to pre-packaged boxed products and cannot handle the direct placement of unpackaged crisps into the tray. Impact damage is a concern, as the instantaneous pushing force of the push rod causes product collisions, resulting in a product damage rate exceeding 8%. Furthermore, the device lacks precision, with a mechanical push rod positioning error of ±5mm, making it difficult to match with precision trays.

[0009] Therefore, there is an urgent need for a conveying device that is simpler in structure, more efficient, lower in cost, and can more quickly and reliably complete the automatic tray packaging of egg yolk pastries. Utility Model Content

[0010] The purpose of this utility model is to provide a conveying device for producing egg yolk pastries in order to solve the above-mentioned technical problems.

[0011] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0012] This utility model proposes a conveying device for producing egg yolk pastries, including a main conveyor belt, a vertical rotating positioning turntable, a packaging pallet conveyor belt, a synchronous drive and control system, and a guide slide.

[0013] The main conveyor belt is used to transport the arranged egg yolk pastries. The vertical rotating positioning turntable is located at the end of the main conveyor belt. The edge of the vertical rotating positioning turntable has multiple independent work stations evenly distributed. Each work station has an opening at the top for receiving egg yolk pastries and a controllable opening and closing discharge port at the bottom.

[0014] The packaging pallet conveyor belt is located directly below the vertical rotating positioning turntable and is used to transport and position empty plastic packaging pallets.

[0015] The synchronous drive and control system drives the main conveyor belt, the vertical rotary positioning turntable, and the packaging pallet conveyor belt to move synchronously.

[0016] As a preferred technical solution of this utility model, the controllable material discharge port at the bottom of the workstation is composed of a movable base plate or a door, and is connected to a material discharge port driving mechanism that drives it to open and close quickly.

[0017] As a preferred technical solution of this utility model, the workstation is equipped with a sensor for detecting the arrival of the egg yolk pastry.

[0018] As a preferred embodiment of this utility model, the guide slide is disposed between the material inlet of the vertical rotating positioning turntable and the opening of the plastic packaging tray on the packaging tray conveyor belt, for guiding the egg yolk pastry to fall into the tray.

[0019] As a preferred embodiment of this utility model, the packaging tray conveyor belt is provided with positioning clamps for fixing plastic packaging trays.

[0020] As a preferred embodiment of this utility model, the inner wall of the work station is smooth and its size is slightly larger than that of an egg yolk pastry.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. The vertical turntable landing mechanism achieves a single-station operation cycle of 0.8-1.2 seconds, with a packaging speed of up to 200 pieces / minute, which is 5 times faster than a robotic arm;

[0023] 2. Zero product damage: Gravity guidance combined with smooth inner walls of the workstations eliminates the need for mechanical gripping throughout the process, reducing the product breakage rate to below 0.2%.

[0024] 3. Simplified structure and reduced costs: The robotic arm and complex transmission mechanism are eliminated, core components are reduced by 70%, and manufacturing costs are reduced by 40%;

[0025] 4. Precise and reliable positioning: Three-axis synchronous control ensures that the material inlet and tray are aligned with an accuracy of ±0.3mm, and the tray acceptance rate is >99%. Attached Figure Description

[0029] Assume a vertical rotating positioning turntable with 4 evenly distributed workstations, corresponding to angles of 0°, 90°, 180°, and 270°;

[0030] The main conveyor belt continuously transports egg yolk pastries at a speed of 4 per second, while the turntable rotates at a constant speed of 30 rpm. The four workstations simultaneously receive the pastries during rotation. When the first workstation reaches 270°, the turntable simultaneously detects that the egg yolk pastry at the fourth workstation has reached its position and instantly opens all four openings. The four egg yolk pastries fall simultaneously along the slide onto the four-piece plastic tray on the packaging tray conveyor belt below. The openings close simultaneously within 0.2 seconds, and the turntable continues to rotate without stopping, starting a new cycle of receiving and dropping the pastries.

[0031] like Figures 1 to 2 As shown, this utility model proposes a conveying device for producing egg yolk pastries, including a main conveyor belt, a vertical rotating positioning turntable, a packaging pallet conveyor belt, a synchronous drive and control system, and a guide slide.

[0032] The main conveyor belt is used to transport the arranged egg yolk pastries. The vertical rotating positioning turntable is located at the end of the main conveyor belt. The edge of the vertical rotating positioning turntable has multiple independent work stations evenly distributed. Each work station has an opening at the top for receiving egg yolk pastries and a controllable opening and closing discharge port at the bottom.

[0033] The packaging pallet conveyor belt is located directly below the vertical rotating positioning turntable and is used to transport and position empty plastic packaging pallets.

[0034] The synchronous drive and control system drives the main conveyor belt, the vertical rotary positioning turntable, and the packaging pallet conveyor belt to move synchronously.

[0035] The controllable material discharge port at the bottom of the workstation is composed of a movable base plate or a door, and is connected to a material discharge port drive mechanism that drives it to open and close quickly.

[0036] The workstation is equipped with a sensor for detecting when the egg yolk pastry is in place.

[0037] The guide slide is located between the material drop port of the vertical rotating positioning turntable and the opening of the plastic packaging tray on the packaging tray conveyor belt, and is used to guide the egg yolk pastry to fall into the tray.

[0038] The packaging tray conveyor belt is equipped with positioning clamps for securing the plastic packaging trays.

[0039] The inner wall of the work station is smooth and its size is slightly larger than that of an egg yolk pastry.

[0040] Working principle:

[0041] The synchronous drive and control system drives the main conveyor belt, rotary positioning turntable, and packaging tray conveyor belt to move in strict coordination. The specific process is as follows:

[0042] With continuous feeding and turntable rotation, the main conveyor belt continuously feeds the egg yolk pastries into the turntable station at a uniform speed, and the turntable does not stop throughout the entire process.

[0043] Parameterized dynamic triggering: when the workstation rotates to the preset material dropping angle of the machine, the material dropping port of the workstation is immediately triggered to open.

[0044] Gravity feeding and dynamic receiving: the egg yolk pastry falls vertically by gravity, while the empty trays on the packaging tray conveyor belt move synchronously to the bottom of the feeding port, achieving precise receiving during movement;

[0045] After the material inlet is closed, the turntable rotates at a constant speed to the next receiving position, and the tray conveyor synchronously transfers the new tray, with no stopping or waiting throughout the entire process.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model 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 basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
