VACUUM FOLDING CREAM SPREADER MACHINE

Abstract

The invention relates to a vacuum folding cream dispensing machine that performs folding, alignment, and pressing functions in wafer production lines without the need for a blower system, operating solely on the principle of precise vacuum, preserving product integrity, and significantly reducing maintenance downtime. In this system, a localized pressure difference is created through multi-point micro-holes in a vacuum plate that contacts the bottom surface of the wafer sheets. The wafer sheets are then folded and aligned in a controlled manner without breakage or geometric distortion. By completely eliminating the blower, energy consumption, maintenance requirements, clogging, and contamination problems are eliminated; stable, repeatable product quality is achieved at high speeds in the production line.

PREVIOUS TECHNIQUE 10 In current cream spreading machines, the folding of wafer sheets is generally servo-controlled mechanical arms, pneumatic pushers, alignment units, and pressure balls. This is done through these systems. In these systems, the folding process is not stable, especially 3 It is known that suppression is insufficient in lines that form blocks of kg and above. Alignment units require constant maintenance, as the leaves are in contact with the cream. 15 Slip and geometric distortions are frequently observed, and the product during block formation... Ensuring proper arrangement becomes difficult. In known vacuum-assisted systems, the blower operates continuously and production... The intense cream and chocolate vapor in the environment accumulate at the blower inlets, causing blockages. This leads to flow rate loss and line shutdowns. 20 resulting from blower blockage. Pressure fluctuations reduce folding quality, resulting in differences between the blocks produced. It creates porous surfaces, and the machine requires constant cleaning. Due to its fragile and low-strength structure, it does not homogeneously adhere to a vacuum surface. When not unwrapped, the leaves often break or crack during folding. It is a problem. 25 For these reasons, existing systems need to operate stably at high speeds. It supports continuous production with low maintenance requirements and is suitable for delicate materials like wafer sheets. It is not possible to fold the products without breaking them. This situation leads to a more homogeneous It has pressure distribution, is non-clogging, has low energy consumption, and all functions are integrated. This has necessitated a new folding method that brings them together in between. 30 A BRIEF DESCRIPTION OF THE INVENTION The invention involves the use of a vacuum plate alone, without the use of an air blower. integrated into a folding system that operates using a localized pressure difference created on its surface. 2 It relates to a vacuum folding cream dispensing machine. The many features located on the vacuum plate... Thanks to the dotted micro-holes, the vacuum applied to the wafer surface is homogeneous. The product is distributed in this way, and it folds and aligns without breaking or being crushed. By eliminating mechanical folding and alignment units, the system becomes more... It has become compact; maintenance requirements have decreased, energy consumption has dropped, and there are 5 in the production line. Stable product output has been achieved. Our invention involves folding, alignment, and pressing. by bringing together the processes seen in previous techniques in a single vacuum-based module It simplifies the fragmented functional structure and significantly improves the performance of the production line. It improves in this way. LIST OF FIGURES Figure 1. General view of the Cream Dispensing Machine. Figure 2. Discrete View of the Folding Module. Figure 3.

It consists of three main sections, including the printing section. The first section is... wafer sheet folding mechanism fixed chassis section (1); fixed chassis top plate (1.1), drive mechanism (1.2), servo motor (1.3), pneumatic piston cylinder (1.4), system management sensor (1.5), limit and reference sensor (1.6), belt control and limit sensor (1.7) parts and sections, the second part being the wafer sheet folding mechanism 10 movable section (2); movable section chassis (2.1), open / close movable flap system (2.2) from the sensor parts and sections, the third section is the vacuum and pressure section (3); folding section carrier plate (3.1), pressure plate (3.2), vacuum pads (3.3), printing pistons (3.4), z-directional movement wheel (3.5), positioner (3.6) part and It consists of sections. 15 System manager sensor (1.5) pair single layer cream-filled wafer sheet It involves recognizing and controlling the fact that the system has a lid. The product, which is arranged like a single-layer wafer with a cream filling in the middle, comes off the conveyor belt with a lid. if it is not delivered or arrives as a single wafer sheet covered with cream The system does not start the vacuuming and folding process. Single-layered sheets, centered at 20, are coming from the conveyor belt. cream-coated wafer sheet system manager sensor (1.5) pair If detected and verified by this, the machine starts the cycle and It is activated. Pneumatic piston cylinder (1.4) y-direction stepped open / close movement. By lowering the flap system (2.2) in the y direction, single-layer cream-filled center print Stops the unapplied wafer sheet. Drive mechanism (1.2) vacuum and pressure 25 lowers section (3) in the y direction. Vacuum and pressure of the drive mechanism (1.2) Band control and limit sensor (1.7) confirming that section (3) is going down in the y direction. stops the belt. The pressure pistons (3.4) move the pressure plate (3.2) downwards in the y direction. and applies pressure to the single-layered, cream-filled wafer sheet that has been stopped. Along with the pressure... A single-layer wafer sheet with cream filling adheres. The pressure pistons (3.4) press the pressure plate (3.2) 30 It lifts upwards in the y direction. Vacuum pads (3.3) are necessary for vacuuming the pressure plate (3.2). It is positioned at a point below. Airflow to the vacuum pads (3.3) begins. Air As the flow begins, single-layer wafer sheets with cream filling are placed in vacuum pads. (3.3) is held by vacuuming. The servo motor (1.3) drives the drive mechanism (1.2). 4 By passing it through, it lifts the vacuum and pressure section (3) upwards in the y direction. From this moment on The folding process has begun. Here, as the folding process starts, open and close. The movable flap system (2.2) opens its flaps during each landing and take-off movement in the y direction. By opening and closing it, it prevents damage to the delicate wafer sheets. To achieve the desired number of layers in the wafer block, 5 layers of cream-covered wafers are passed through the conveyor belt. A new wafer sheet arrives. A freshly whipped wafer sheet, topped with cream, comes off the conveyor belt. The sensing system manager sensor (1.5) command drives the servo motor (1.3). by activating the mechanism (1.2) the vacuum and pressure section (3) downwards in the y direction The pressure pistons (3.4) move the pressure plate (3.2) downwards in the y-direction and The machine applies pressure to the cream-covered wafer sheet, which has been stopped. This process is repeated for wafer 10. The number of repetitions is sufficient according to the number of layers in the block. The target wafer block layer Once the number is reached, the servo motor (1.3) activates the drive mechanism (1.2). By passing it through, it lifts the vacuum and pressure section (3) upwards in the y direction. Pneumatic piston The cylinder (1.4) lifts the flap system (2.2) which performs an open / close movement upwards in the y direction. Air The system is cut off and the vacuum ends. The system has lifted upwards in the Y direction. 15 Our invention, the cream dispensing machine, uses a vacuum pad without the need for a blower. It has a special vacuum plate consisting of drainage channels and multi-point micro-holes. and this plate is in direct contact with the underside of the wafer sheets. The leaf is approximately 350×730×3 mm in size and has a brittle, low elastic modulus. Due to its structure, the even distribution of vacuum pressure across the surface is of critical importance. 20 It carries. Therefore, the diameter of the holes in the vacuum plate (40-80mm), distribution The spacing (9-15 channels) and geometry of the drainage channels are porous to the wafer sheet. It is designed to support its structure. While the system is operating, the negative pressure created in the vacuum chamber is applied to the vacuum plate. It acts on the wafer foil through micro-holes on its surface. This effect affects the foil's 25 It is designed to prevent sudden pressure surges that could cause it to break. It creates a constant holding force below the wafer fracture limits. The folding motion is caused by a pressure difference applied to specific areas of the vacuum plate. This is made possible thanks to, and thus, the familiar mechanical folding arms or pneumatic The leaves are folded by controlled manipulation without the use of pushers. Folding 30 The position of the wafer sheets afterward is maintained by the surface geometry of the vacuum plate. This eliminates the need for an alignment unit. With the blower removed, the machine does not draw in polluting air from the outside environment. This prevents cream and chocolate residue from accumulating in the system, thus preventing clogging and ensuring thorough cleaning. Downtime is eliminated, and a significant reduction in energy consumption is achieved. Furthermore... Thanks to the multi-point structure of the vacuum plate, the leaf is formed during the block formation phase. This prevents slippage and increases the geometric stability of the resulting wafer blocks. 10 20 30
