Description

INNOVATION IN PACKAGING MACHINE

Technical Field

The invention relates to a new packaging machine developed for making auger handles for paper bags.

The invention particularly relates to a packaging machine in which the auger handle paper is cut, twisted and transferred to a conveyor system for adhering to a paper bag by means of a turret group vacuum system together with reinforcing paper.

State of the Art

Nowadays, when the protection of the environment is becoming increasingly important, the use of plastic bags has started to be abandoned. The use of paper bags, which are much easier and faster to recycle instead of plastic in shopping, provides great benefit in reducing pollution. After the design is selected in the production of paper bags, the production of the bag is started and printing and coating are made according to the design. Then the handle parts are attached to the bag. Paper bags are divided into flat handle, auger handle and bottom paper bags. If a paper bag with auger handle is desired, the handles called cords are attached with manpower at this stage.

In order to reduce the labour requirement in the production of paper bags with auger handles, mechanical systems have started to be used today. In these systems, the auger handle is adhered to the paper bag together with the reinforcing paper by moving on a line. However, when a poor quality rope is used, the rope cannot be held and the line is skipped when the desired form is not available in the system that proceeds by holding the rope. In addition, when the rope breaks, the reinforcement paper is scattered everywhere. Apart from these problems, there is also a space problem. The rope and reinforcing paper glued together can follow a long way to be glued to the bag. The problems experienced in the current technique cause disadvantages such as the inability to produce paper bags quickly and the need for a large area for machine placement due to the large machine dimensions.

As a result, the existence of the need for an improved packaging machine for making auger handles for paper bags that eliminates the disadvantages of the existing technique and the inadequacy of the existing solutions made it necessary to make a development in the relevant technical field.

Brief Description of Invention

The present invention relates to a new packaging machine for making a auger handle for a paper bag, which fulfils the above - mentioned requirements, eliminates all disadvantages and brings some additional advantages.

Based on the state of the art, the aim of the invention is to ensure that the auger handle paper is cut and twisted and transferred to the conveyor system to be glued to the pouch bag together with the reinforcing paper, by means of the vacuum operation of the developed packaging machine.

The aim of the invention is to ensure that the packaging machine can be easily installed and used in narrow I limited spaces by means of its compact structure.

Another aim of the invention is to enable the packaging machine to work faster by means of the short working distance and thus to eliminate the space problem.

Another aim of the invention is to ensure that the auger handle and the reinforcing paper are adhered to the paper bag with a vacuum system by means of two turret groups positioned opposite each other.

Detailed Description of the Invention

In this detailed description, the packaging machine (1000) developed for making an auger handle (B) for a paper bag is described only as an example for a better understanding of the subject matter and without any limiting effect.

The packaging machine (100) shown in Figure-1 comprises a stacking unit (3000) positioned at the inlet; a tear - off unit (4000) where the paper raw material is cut to the desired dimensions; a folding unit (5000) where the cut paper is folded to form a paper bag; and an auger handle unit (2000) operating with a vacuum system where the twisted handle paper is cut, twisted and transferred to the conveyor system to be glued to the paper bag together with the reinforcing paper. In the said auger handle unit (2000) shown in Figure-2, there are two turret groups (2100) shown in Figure-3 for adhering the auger handle (B) and the reinforcing paper to the paper bag with the vacuum system. The turret groups (2100) shown in Figure-4 are positioned mutually in the auger handle unit (2000). At the top of each turret group (2100) shown in Figure-5, the reducer (2101) which drives the cam is positioned. At the bottom of the said reducer (2101), there is a sleeve assembly (2102), which acts as a bearing for the twisted turret drum shaft (2136) to rotate around its axis. The aforementioned turret group (2100) is connected to the body of the auger handle unit (2000) by means of the fixing slat (2103). In the lower part of the fixing slat (2103) shown in Figure-6, there is a reducer shaft (2104) which is connected to the reducer (2101) at one end and to the drive gear (2105) at the other end and which turns the drive gear (2105). Said drive gear (2105) is rotated by the reducer (2101) for adjusting the first side lug cam (2107) depending on the size of the paper bellows. Said drive gear (2105) is connected to the gear (2106) which rotates the twisted clamping part (2109). Said drive gear (2105) and the first side lug cam (2107) located at the lower part of the gear (2106) push the upper vacuum group including the first vacuum body pin (2115) downwards, so that the auger handle (B) is released from the first vacuum part (2132). The second side lug cam (2108) positioned at the end of the said first side lug cam (2107), which moves together with the twisted clamping part (2109) positioned at its lower part, pushes the upper vacuum group including the first vacuum body pin (2115) coming to it in a slightly downward direction, so that the auger handle (B) is pulled away from the first vacuum part (2132) and the paper is removed from the conveyor and transmitted to the first side lug cam (2107). A bearing (2110) is positioned for rotation of said twisted clamping part (2109). In the lower part of said twisted clamping part (2109), the turret lug camshaft (2111) is positioned, which connects the first vacuum cam (2112) to the fixing slat (2103). The first vacuum cam (2112), which traces the path to be followed by the assembly containing the first body pin (2115), is connected to the turret lug cam shaft (2111). The lug cam bearing (2113) moves on the first side lug cam (2107) and the second side lug cam (2108) for vacuum pulling and releasing the auger handle (B). The lug cam bearing (2113) and the first vacuum body pin (2115) are fixed by the pin (2114). Said first vacuum body pin (2115) carries the lug cam bearing (2113) for movement of the vacuum assembly on the first side lug cam (2107) and the second side lug cam (2108). For rotation of said first vacuum body pin (2115), a body pin bearing (2116) is used. For rotation of said vacuum group, a vacuum group gear (2117) is connected to the lug cam bearing (2113). Inside said vacuum group gear (2117), a spring (2118) is positioned which pushes the vacuum group, which descends when passing through the first side lug cam (2107) and the second side lug cam (2108), upwards when idle. In order to prevent the said vacuum group gear (2117) from moving upwards, a snap ring (2119) is positioned at its lower part. The idler bottom roller (2120), which is the shaft of the vacuum group, is connected to the vacuum group gear (2117).

In the turret group (2100) shown in Figure-7, the sheel (2122), which connects the vacuum group to the rack and pinion (2135), is connected to the rack and pinion (2135) with the fastener (2121). A vacuum shaft fixing bearing (2123) is used to prevent the said first vacuum body pin (2115) from rotating to the right and left. Roller bearing (2124) is connected for rotation of said idler bottom roller (2120). A vacuum part (2125) is connected to the sheel (2122) for the air outlet. On the aforementioned vacuum part (2125) and the twisted turret drum shaft (2139), a hose connector (2126) is positioned between which an air hose is connected. The fourth vacuum part (2127), which is connected to the vacuum part (2125), is in the down position when the vacuum group passes through the first side lug cam (2107) and the second side lug cam (2108), and in the up position when in the gap. Said fourth vacuum part (2127) is provided with the second vacuum part (2128), the spring (2129), a third vacuum part (2130) and a sealing O-ring (2131) to prevent air leakage. The first vacuum part (2132), which holds and releases said auger handle (B), moves together with the fourth vacuum part (2127). The lama bearing (2133), which moves in the groove in the vacuum cam (2112), is coupled to the rack and pinion (2135). The rack and pinion (2135), which is connected to the linear rail (2134), moves to the right and left with the help of the linear bearing (2137) below it. The second linear rail (2136), which is used to ensure that the aforementioned rack and pinion (2135) can follow a comfortable path in the vacuum cam (2112), enables the rack and pinion (2135) to move with the help of the linear bearing (2137). The second linear rail (2136) moves on the linear bearing (2137). While the aforementioned rack and pinion (2135) rotates following the path of the first vacuum cam (2112), the linear rail (2134) rotating the vacuum group gear (2117) also rotates the first vacuum part (2132).

The first turret plate (2138) shown in Figure-8 preferably carries 6 vacuum groups and rotates together with the twisted turret drum shaft (2139). Said twisted turret drum shaft

(2139) rotates the turret group (2100) by means of the sprocket (2140). Said sprocket

(2140) rotates in connection with the chain and rotates the turret assembly (2100). Said sprocket (2140) is fixed to the twisted turret drum shaft (2139) by means of a conical lock

(2141). For the air flow, a pneumatic rotary joint fitting (2142) is positioned at the bottom of the turret group (2100). In the inventive packaging machine (1000), the auger handle (B) is transferred to the turret group (2100) by the conveyor system. In the turret group (2100), it is taken in the desired position with the vacuum and cam system and left to the other conveyor in the desired position. The first turret group (2100) rotates with the help of sprocket (2140). The first turret plate (2138), which is connected to the twisted turret drum shaft (2139), also carries 6 vacuum stations on it. These stations have continuous vacuum but cannot hold the paper. In order to catch the auger handle (B) coming to the turret group (2100), the vacuum groups first come to the second side lug cam (2108). Here, the second side lug cam (2108) pushes the vacuum group including the following lug cam bearing (2113) slightly downwards. At the same time, the first vacuum part (2132) also moves downwards in a pulsating manner towards the auger handle (B) and catches the paper. As the auger handle (B) moves towards the first side lug cam (2107), it has to rotate around its axis in order to be released at the right place. This is done with the help of the group including the linear rail (2134) and the first vacuum cam (2112). The lama bearing (2133) rotates together with the first turret plate (2138). The lama bearing (2133) moves on the groove on the first vacuum cam (2112). Due to the shape of this groove, the second linear rail (2136), the linear bearing (2137) and the linear rail (2134) also reciprocate. The linear rail (2134) rotates the vacuum group gear (2117) working together with itself. Thus, the auger handle (B) is also rotated. At this stage, the rotating suction cup group has reached the stage of releasing the auger handle (B). The suction cup group coming to the first side lug cam (2107) is pushed a little further downwards due to the shape of the part and the vacuum is cut off. Thus, the auger handle (B) is left in the desired position. The first side lug cam (2107) is adjusted depending on the bellows size of the paper and this adjustment is made by turning the twisted clamping part (2109) connected to the gear (2106) as a result of the reducer (2101) turning the drive gear (2105) and gear (2106).
