Description

Technical Field

[0001] The invention belongs to the technical field of vacuum packaged egg processing equipment, and in particular relates to a mechanism for loading vacuum packaged eggs into foam boxes. Background Art

[0002] After the eggs are vacuum packed and sealed, they need to be transported to a high-temperature sterilization furnace for high-temperature sterilization. After cooling and standing, they are first placed in a foam box, and then the foam box is placed in a gift box, and finally packed and shipped. Since the vacuum packaging bag will be wrinkled and deformed during the plastic sealing and high-temperature sterilization process, the consistency is poor, and the skirt of the plastic sealing bag occupies a large space, etc., egg packaging manufacturers on the market currently generally use manual vacuum packaging eggs into foam boxes. This method requires multiple workers to manually insert the vacuum-packed eggs into the foam box, which has high labor costs, low efficiency, and product quality fluctuates due to human factors. In order to improve production efficiency, people try to use a vacuum suction cup manipulator to absorb the vacuum-packed eggs and then put them into the foam box. Although this method can improve production efficiency, due to the vacuum packaging bag on the outside of the vacuum-packed eggs, affected by the skirt of the vacuum packaging bag, the vacuum eggs are flat after being packaged. When the vacuum suction cup absorbs and lowers the vacuum-packed eggs, the vacuum eggs are also flat. It has the following technical problems:

[0003] In order to save space, the grids for accommodating vacuum-packed eggs in the foam box are made according to the state that the vacuum-packed eggs are placed vertically. Therefore, the method of using vacuum suction cups cannot adapt to the existing foam boxes. If the grids for accommodating vacuum-packed eggs in the foam box are made according to the state that the vacuum-packed eggs are placed horizontally, affected by the skirt of the plastic bag, the grids for accommodating vacuum-packed eggs in the foam box must be set relatively large to accommodate the skirt of the plastic bag, further increasing the overall size of the foam box. In addition, since the grids for accommodating vacuum-packed eggs in the foam box are large, the vacuum-packed eggs are easily shaken by vibration in the grids, and the shells are easily damaged by shaking in the grids during transportation. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Embodiment 1, the present invention provides a vacuum packaging egg product into the foam box mechanism, see Figure 1-Figure 5, including: a first conveyor belt 1, used to convey the foam box; a blocking device, used to fix the foam box 3 to a predetermined position after the foam box reaches the predetermined position; a shutter mechanism 5, which is arranged corresponding to the blocking device, and the shutter mechanism is located above the first conveyor belt. The shutter blades of the shutter mechanism are used to receive the vacuum-packed eggs placed on the vacuum suction cup, and can be turned over 90° to drive the vacuum-packed eggs to fall vertically to the grid g of the corresponding foam box. In the present application, the size of the grid of the foam box can be made slightly smaller than the edge size of the plastic bag of the vacuum duck egg; a needle plate 6, located on one side of the shutter mechanism, and the needle plate can be turned from a vertical state to a horizontal state , so that the ejector pin on the needle plate presses the corresponding vacuum-packaged eggs into the grid of the corresponding foam box. In this embodiment, the louver blade is preferably provided with a V-shaped notch so that the empty packaged eggs can be stably placed thereon. In order to facilitate timely covering the foam cover on the foam box, the empty packaged eggs into the foam box mechanism may also include a second conveyor belt 1-1, which is arranged parallel to the first conveyor belt and is used to transmit the foam cover 4; the blocking device is also used to fix the foam cover to a predetermined position after the foam cover reaches the predetermined position, so that the foam cover can be conveniently obtained and covered on the foam box after the vacuum-packaged eggs are loaded into the foam box.

[0025] When the above-mentioned mechanism for loading vacuum-packed eggs into foam boxes is in operation, when the foam box arrives at the predetermined position with the first conveyor belt, the blocking device fixes the foam box to the predetermined position, and the vacuum suction cup manipulator loads the flat duck eggs into the shutter blades of the shutter mechanism. The shutter blades flip 90 degrees to drive the vacuum-packed eggs to fall onto the grids of the corresponding foam box. At this time, the flat duck eggs rotate and become vertical. Since the edge size of the vacuum duck eggs is slightly larger than the grid size of the foam box, the vacuum duck eggs will be piled on top of the grid of the foam box. At this time, the needle plate can be controlled to flip from a vertical state to a horizontal state, so that the ejector pins on the needle plate will flip and press the corresponding vacuum-packed eggs into the grids of the corresponding foam box. This structure can adapt to the existing foam boxes made according to the state in which the vacuum-packed eggs are placed vertically, and there is no need to redesign the foam box. Compared with the foam boxes designed according to the state in which the vacuum-packed eggs are placed horizontally, the overall size of the foam box is reduced, and the vacuum-packed eggs are in closer contact with the grids, and are not easily shaken by vibration in the grids, and the shell is not easily damaged during transportation.

[0026] Example 2: Example 2 is a specific implementation of Example 1. Figure 1-Figure 5The vacuum-packed egg loading foam box mechanism also includes a bracket 11, the top surface of the bracket forms a first frame a, and when the shutter blades are turned over, the vacuum-packed eggs can pass through the hollow part of the first frame and fall onto the grid of the corresponding foam box; the shutter mechanism includes a second frame, the second frame is slidably connected to the first frame, at least one row of shutter blades is arranged in the second frame, and a partition e is arranged in the second frame, and the partition separates the internal space of the second frame into a plurality of grids f corresponding to the shutter blades, so that in the process of turning over the shutter blades, the grids block the vacuum-packed eggs on both sides, and the second frame blocks the vacuum-packed eggs on the front side. The vacuum-packed eggs are blocked to prevent them from tilting, and the downward pressure of the needle plate is conducive to the vertical loading of the vacuum-packed eggs into the foam box. In this embodiment, multiple louvers in each row are fixed to the same rotating shaft b, and the rotating shaft is hinged or rotatably connected to the second frame. A first connecting rod c and a second connecting rod d are provided on one side of the second frame. The first connecting rod and the second connecting rod are hinged or rotatably connected. The end of the first connecting rod that is not connected to the second connecting rod is fixedly connected to the rotating shaft, and the end of the second connecting rod that is not connected to the first connecting rod is connected to a driving device for driving the second connecting rod to move, and the driving device can drive Moving the second connecting rod drives the first connecting rod to rotate and then drives the louver blades to flip each other between the horizontal state and the vertical state. Preferably, the length of the first connecting rod is smaller than the length of the second connecting rod to adapt to the thickness of the second frame; the second frame is connected to a support plate, and the driving device is fixed on the support plate. The driving device is preferably a cylinder 9, and the second connecting rod is hinged or rotatably connected to the power output end of the cylinder. The support plate is fixedly connected to the second frame, and the support plate is slidably connected to the first frame. A bearing seat 13 is fixed on the support plate near both sides of the first frame, and the two bearing seats A first gear 7 is arranged between the first gear and the second gear. The first gear is sleeved on the rotating shaft 14. The two ends of the rotating shaft pass through two bearing seats and are rotatably connected with the two bearing seats. The two ends of the rotating shaft are fixed with connecting blocks 15. The needle plate is fixed on the two connecting blocks. A stepper motor 8 is arranged on the support plate. The motor shaft of the stepper motor is fixed with a second gear i. The second gear meshes with the first gear. A support beam h is arranged on the first frame. A through motor 12 is fixed on the support beam. The power output end of the through motor is connected with the second frame to drive the second frame to move forward and backward. In this structure, when the shutter blades are turned over, the cylinder 9 works to drive the second connecting rod, the first connecting rod and the rotating shaft to move, so that the shutter mechanism rotates 90°, and the duck eggs placed flat rotate and become vertical. The stepper motor 8 works to drive the second gear and the first gear 7, so that the needle plate 6 rotates and presses down the duck eggs. After the pressing is completed, the cylinder 9 and the stepper motor 8 are reset to reset the needle plate 6 and the shutter mechanism 5.In actual production, the number of rows of the needle plate is less than the number of rows of the grids of the foam box. Preferably, the number of rows of the needle plate and the louver blades are both two rows. In this way, during the flipping of the needle plate, after the needle plate in the rear row contacts the corresponding vacuum-packed eggs, the distance between the needle plate in the front row and the vacuum-packed eggs is small and can be ignored, which is conducive to the consistency of the force applied by multiple ejectors and the vacuum-packed eggs. The present application can also set the length of the needle plate in the front row to be slightly smaller than the length of the rear row, so that the two rows of ejectors contact the vacuum-packed eggs at the same time so that the force applied to the vacuum-packed eggs is consistent. After the front two rows of vacuum-packed eggs are pressed into the foam box, the needle plate 6 and the louver mechanism 5 are reset, and then the through-type motor 12 works, and the louver mechanism 5 and the needle plate 6 slide to the rear two rows through the slider 10 installed on the bracket 11, and the egg loading and egg pressing operation steps are repeated until the box loading steps of the entire box of vacuum-packed eggs are completed. Taking vacuum-packed duck eggs as an example, the duck egg foam box is generally 4*5 in size, with a louver length of 60mm and a V-shaped notch on it, so that the duck eggs can be stably placed on it. The equipment loads two boxes of eggs at the same time each time. In order to avoid interference between the ejector pins and the louver blades, the two boxes are loaded with eggs in intervals. The first and third rows are loaded first, then the second and fourth rows, and finally a row of eggs is taken separately to load the fifth row. In this way, during the needle plate flipping and pressing down, only one of the two adjacent rows of ejector pins presses down the vacuum-packed eggs, and the other row of ejector pins will not interfere with the corresponding louver blades of the row when rotating. It is especially suitable for structures with two rows of grids in the foam box that are close to each other (such as foam boxes for small firewood eggs). After the eggs are loaded, the blocking cylinder 2 is reset, and the foam box and the foam cover are transferred to the next station through the belt line. During this process, when the needle plate is in a vertical state, the duck egg gripper can be avoided.

[0027] In the present application, the blocking device is preferably a blocking cylinder 2, on which a detection device for detecting a foam box is installed. The detection device is used to detect that the foam box reaches a predetermined position and then start the blocking cylinder to press the foam box against the bracket j of the first conveyor belt. The detection device can use an existing device; the ejector pin on the needle plate is preferably cylindrical, and a force feedback sensor is installed on the ejector pin. The feedback sensor is used to convert the force between the ejector pin and the vacuum-packed eggs into an electrical signal, so as to connect the control system to identify the pressing state of the duck eggs, and then control the ejector pin to flip or stop flipping. This structure is conducive to the automation of vacuum-packed egg boxing.

[0028] The above-mentioned embodiments only express the implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
