TECHNICAL FIELD

The invention relates to an innovation in a conveyance system of packaging machines for multi-row and divided solid foods.

BACKGROUND

The solid food packaging machines used today are generally for the packaging of products in multi-layer blocks up to two rows. In these systems, the product is conveyed on a chain up to the jaw by pushers identified as “the soldier”, which are placed sequentially at certain intervals. This conveyor chain makes a U- turn on a gear that gives the movement so that the jaw has a distance to enable the soldiers to be closed while lying down. These pushers, which are selected according to the size of the product to be packaged, are went down lying parallel to the ground just before the jaw where packaging is provided. It will not be possible to push the product with the soldier after this stage because the lower part of the package is heat sealed. Therefore, just before the bottom of the pack is sealed, it is went down lying in the cavity slightly larger than the soldier pushing the product. The space required for this movement of the soldiers and taking them under the line is shown in FIG. 1 , FIG. 2 and FIG. 3. Since these systems in the known technique have a single row of chains and soldiers working as described above, maximum two rows and single layer or single row multi-layer packaging can be made. It is not possible to pack divided products with three or more rows and multiple layers with these systems. Because while the products are pushed by the soldier, the soldier must be in contact with the product in every row. Due to the necessity that the roll up gap in the roll up box must be larger than the size of the soldier, the products left in the middle of the product row will fall down from the space where the soldier will be went down, because of the product which has a width smaller than the soldier's. This means that the packaging process has failed. The solution of this problem with more than one chain is not possible as it requires adjusting the number of chains and the location of the chain each time the number of rows changes. Besides, increasing the number of chains means increasing the drive power and tail width. In product changes, it means that the tail design will be completely changed. These systems in the known technique have a continuous and rapid packaging capacity of 120-130 pieces per minute (horizontal product group with 2 rows from the top). Since 120- ISO packaging per minute requires a rapid work, when the plastic soldiers that push and convey the products start to descend in the lying position, the metal plate in the roll up gap (soldier fall gap) has a friction continuously and rapidly. The plastic soldiers exposed to abrasion, friction and tension of the chain on this guide are broken after a short time due to friction and they are replaced with their spare parts at the end of each break. This situation will cause the loss of some of the soldiers who lined up and the groups to be packaged to be united. As a result, the packing order and process will be disrupted. The necessity of tension in the use of the chain and a second tension resulting from the change of position of the soldier increases the friction coefficient, causing a deformity in the alpolen (UHMW 1000) guide and plastic soldiers over time. The soldier (product pusher), due to its position, cannot be permanently protected from wear and chain tension on the guide. It is necessary to readjust the alpolen (UHMW 1000) chain guides precisely in place during the assembly in order for the fall process to take place, right in the space that provides the fall of the soldier. Due to the lack of support at the bottom of the chain during assembly and the downward weight of the soldiers (product pusher), the chain causes an unwanted deflection towards the ground. In order to correct this deflection, it needs to be adjusted again. This situation causes job loss.

BRIEF DESCRIPTION OF THE INVENTION

The invention is the conveying system of packaging machines used for multi row and multi pieced solid foods that we have developed to solve the technical problems experienced in the state of the art. In the process of packaging multi-row, multi-layer and multi pieced foods, it is a transport system that requires a little more space than the thickness of the soldier to go down, regardless of the size of the soldier, and works by pulling the soldier down without disturbing the vertical position. The drive of the conveying system is provided by two separate chains with off-axis. In this way, without the need for a guide that allows the soldier to stand upright, the tension created by the misalignment of the chains and the same at every point of the system can be provided to stand upright. In the production of soldiers against friction and abrasion (product propellant), sheet metal material was used instead of plastic material. In the Alpolen (UHMW 1000) chain guide, the fall of the soldiers (product pusher) is provided by a double gear system. In the double gear system, there is no sagging because the soldiers are given a vertical descent and the soldiers are not reversed.

DETAILED DESCRIPTION OF THE INVENTION Invention is a conveying mechanism comprising a motor (1.1), at least two opposing big gears (1.2) with off-axis, a small gear (1.3) increasing the rate of fall of the soldier, a transmission gear (1.4) that drives two chains with a single engine, a chain (1,5) placed on the small gear which is placed on the big gear with off-axis carrying soldier car, a soldier (1.6) pushing the product to be packaged into the packaging, a soldier car (1.7) that allows the soldier to be transported in balance between two chains with off-axis, a fall gap (1.8) that allows the soldier to pass under the line after bringing the product to the packaging section, a drive transmission chain tensioner mechanism (1.9) used to tolerate speed differences and the chain tensioner mechanism (1.10) that ensures the chain mechanism carrying the soldier's car is always on the same tension.

The motor (1.1 ) is the component that drives the chains (1.5) that perform the transmission function in the transport mechanism (1) by means of gears. The drive taken from the motor (1.1) is transferred to the large gear (1.2) located close to it. The large gear (1.2) that takes the movement transfers the movement to the transmission gear (1.4) positioned in front of the other shaft with the help of the transmission gear (1.4) located behind it on the same shaft. The motion taken to the opposite large gear (1.2) positioned with the off-axis is transferred in the same way and the movement of the two chains with the off-axis is provided with equal speed. Equal speed operation of at least two off-axis chains (1.5) with a single motor (1.1) enables the conveying mechanism (1) to transport the product up to packaging without any problems. The soldier (1.6) used to move the product is positioned on the soldier's car (1.7), which is tensioned between two chains (1.5) with an off-axis. Thanks to our system that moves the product working in this way, there is no wear as the soldier car (1.7) and the soldier (1.6) do not have a friction surface. In this way, the transport system continuously provides thrust with the same performance, and the problems of early fall of the soldier (1.6) at the packing line are completely eliminated. The circular transport system works by turning the soldier (1.6) back from the packing line. At this line, the assembly set comprising the soldier car (1.7) and the soldier (1.6) is passed through the drop gap (1.8) vertically below the line and its return is provided. While the assembly set comprising the soldier car (1.7) and the soldier (1.6) is taken under the line, it is ensured that it descends quickly because of the small gear’s (1.3) diameter used in the road it will follow. During the return, the assembly set comprising the soldier car (1.7) and the soldier (1.6) comes to the product taking starting section from the bottom of the line in an upright position, not hanging downwards. In the known technique, the problem of the soldier needing a space larger than its own height, as it moves to the packaging line while it is advancing, because it lies backwards to pass under the line, is eliminated with our invention. Thus, it has become possible to use large size soldiers for the packaging of multi-layered or more than two-row products. This transport system, which can be used especially in food products such as wafers, enables the trouble- free packaging of small-piece products with more than two rows or multiple layers. The drive transmission chain tensioning mechanism (1.9) is used to tolerate the speed differences of the chains that provide drive transmission during the drive. Thus, the speed at each point of the system remains the same and the assembly set comprising the soldier car (1.7) and the soldier (1.6) is constantly kept in balance. The chain tension mechanism (1.10) is used to keep the tension of the chain (1.5), which performs the carrying function of the assembly set comprising the soldier car (1 .7) and the soldier (1 .6) on the gears.

As an example, the operation of the transport mechanism (1 ) is as follows; the assembly set consisting of the soldier car (1.7) and the soldier (1.6) comes to the section called the tail of the packing machine. The machine called boxer in this section pushes the product to be packaged in front of the soldier (1.6) going towards the packing point. The soldier (1 .6) advances the product between the guide plates up to the packing point. This motion transmission has been detailed above. When it comes to the packaging section, the product is pushed by the soldier (1.6) until it enters the cellophane. Meanwhile, cellophane is sealed from the bottom with the help of hot discs. Thus, the product is rolled by the cellophane and the movement continues in the cellophane. In the meantime, the assembly set comprising the soldier car (1.7) and the soldier (1.6) is moved on a narrow diameter on the small gear (1.3) and taken under the line from the fall gap (1.8). Here, the assembly set comprising the soldier car (1.7) and the soldier (1 .6) is carried to the very beginning of the tail without changing position around the big gear (1.2). The cycle continues like this.
