专利摘要:
Packing machines which manufacture packing containers of the so-called gable-top type from flexible packing laminate frequently handle prefabricated, tubular packing container blanks which are provided with a bottom through folding in and sealing of a number of bottom wall panels. The bottom is pressed down and sealed whilst the blank is supported by a mandrel on a mandrel wheel. In order to avoid the transmission of the pressing-down and selaing forces to, and stressing of, the axle and bearing of the mandrel wheel an arrangement is proposed in accordance with the invention which is designed so that the compressive forces generated by means of the pressure devices (5) are absorbed by a tie rod (30) which connects the pressure application arrangement (14) with the axle (19) of the mandrel wheel (3), so that the forces are absorbed internally without stressing the mandrel wheel axle (19) or other surrounding elements.

专利说明:

The invention relates to a packaging technique, namely, devices for sealing the bottom of a bag of laminated material to a packaging machine comprising rotary disks with radially arranged bag holders.
The purpose of the invention is to increase reliability.
Fig. 1 schematically shows a packaging machine in which a device for sealing the bottom of a bag is used, which is made in accordance with the invention; Fig. 2 shows a device for sealing the bottom of a bag, a side view with a partial section of rotary disks with mandrels and packet blanks placed on them; on fig.Z - the same section.
The packaging machine contains a magazine (not shown) for blanks 1 of packages, from which they are fed to mandrels 2 radially mounted on disks 3, which are mounted with discrete rotation. but the packaging machine has two disks 3, but there may be more.
The machine also contains a device 4 for heating (softening) the material of the workpiece 1, a device for forming the bottom of the bag 5, a device 6 for sealing it, a pipe 7 through which into the bag 5 under; the pressure from the tank 8 by means of the pump 9 supplies the product to be packed. Further along the process are located

a hot air heater 10 that heats the upper unsealed part of the bag 5, whereby the thermoplastic layers acquire the temperature required for sealing, the seal 11 to hold the upper edges of the bag 5, the control device 12 and the exit conveyor 13.
The device 6 for sealing the core of the package 5 is located slightly above the area of rotation of the discs 3 with the mandrels 2 and is attached to the frame 14 of the packaging machine by means of a housing 15 protruding from the frame 14. In the frame 14, a shaft 16 is mounted with a lever 17 attached thereto. - Achkom (not shown), driven by the main shaft of the machine. Shaft 18 is also mounted in frame 14, on which disks 3 with mandrels 2 are fixed. Shaft 18 of disks 3 is also connected to the main shaft of the packaging machine.
A shaft 19 is mounted in the housing 15, on which two eccentrics 20 are fixed, each of which is located above the corresponding disk 3. The shafts 16 and 19 are connected to each other.

peruraura, in which the layers of thermoplastic are fastened. With further rotation of the disk 3, the bottom surface of the workpiece 1 is bent in a known manner along the bending lines, the bottom becomes flat, the bottom walls partially overlap and can be sealed against moisture penetration.
As soon as the blank 1 of the bag 5 with the bottom walls curved downward is located under the device 6 for sealing the bottom, the lever 17 is actuated by a cam connected to the main shaft of the machine, whereby the shaft 16 rotates and at the end of the rotation of its groove 23 is in the plane passing through the shaft 19 eccentrics 20 and the axis of rotation of the disk 3 with mandrels 2. Due to the pin 22, the shaft 19 of eccentrics 20 rotates a certain angle, as a result of which both eccentrics 20 displace the shafts 27 of the presses 24 in the direction from the axis of rotation of the disks 3 mandrels 2 In this position, the plates 26 of the presses 24 lie on the walls of the blanks 1, folded down onto the free edge

22, located at the end of the shaft 19, and the groove 23 at the end of the shaft 16. The groove 23 is located so that in the working position of the device 6 it is located in a plane in which the axis of rotation of the disks 3 and the longitudinal axis of the shaft 19 of eccentrics 20 lie on eccentrics 20 presses 24 are fastened, each of which consists of two plates 26 placed one above the other and connected by a spring 25 and has a shaft 27, one end of which rests on an eccentric 20. One of the plates 26 (lower) of each press 24 is fixed on the shaft 27 by the guide element 28. The end of the shaft 19 eksts The centrics 20 rotate in the sleeve 29 and can slide in the housing 15.
Between the eccentrics 20 is placed the rod 30, which at one end is fixed on the shaft 19 of the eccentrics, and the other - on the shaft 18 of the disks 3.
During operation of the packaging machine containing the proposed device, the workpiece 1, due to the discrete rotation of the disk 2 with the mandrels 2, goes to the device 4, which heats the bottom of the workpiece 1 of the package 5 protruding beyond the edge of the mandrel 2 to 50

Vary together with a predetermined force determined by the spring 2 The shafts 27 of the presses 24 have a slightly larger stroke than the gap between the surfaces of the mandrel 2 and the bottom plate 26 of the press 24, so they make an additional movement in the direction of the axis of rotation of the disks 3 with mandrels 2 under the action of the compressive force of the springs 25. Due to the resistance to this movement, the shafts 27 of the presses 24 slacken the shaft 19 of the eccentrics 20 against the axis of rotation of the discs with the mandrels 2, which is possible because the shaft 19 of the eccentrics 20 is in suspension. The pin 22 of the shaft 19 of the eccentrics 20 slides slightly upward in the groove 23 of the shaft 16, and the other side of the sleeve 29 accordingly slides slightly upward in the groove; made in housing 15. Ba 19 eccentrics 20 is displaced by 0.5-1 mm, and since rod 30 can rotate on the central part of eccentric shaft 19, it also slightly displaces in the same direction. The placement of the rod 30 is limited by a gap in its rotational support, which is about 0.5-1 mm.

together with a predetermined force determined by the spring 25. The shafts 27 of the presses 24 have a slightly larger stroke than the gap between the surfaces of the mandrel 2 and the bottom plate 26 of the press 24, so they make an additional movement in the direction of the axis of rotation of the disks 3 with the mandrels 2 under by compressing the force of the springs 25. Due to the resistance to this movement, the shafts 27 of the presses 24 slightly raise the shaft 19 of the eccentrics 20 relative to the axis of rotation of the discs 3 with the mandrels 2, which is possible since the shaft 19 of the eccentrics 20 is in the suspended ski The pin 22 of the shaft 19 eccentrics 20 slides slightly up in the groove 23 of the shaft 16, and the other side of the sleeve 29 accordingly slides slightly up in the groove; made in the housing 15. The shaft 19 of the eccentrics 20 is displaced by 0.5-1 mm, and since the rod 30 can rotate on the central part of the shaft 19 of the eccentrics, it is also slightly shifted in the same direction. The movement of the rod 30 is limited by a gap in its rotational support, which is about 0.5-1 mm.
Once this gap is selected, the tensile force in the rod 30, equal to the total compressive force on the mandrels 2, increases. Since the rod 30 is also connected to the shaft 19, on which presses 24 are fixed by means of eccentrics 20, and to the shaft 18, on which the disks 3 are mounted with mandrels 2, the forces on the shafts 18 and 19 are balanced.
Due to this design, the forces arising from the operation of presses 24 (sealing the bottom of the bag 5) are prevented from being applied to the mandrels 2, the disks 3, the drive shaft 18 of the disks 3 and the bearing of this shaft located in the frame 14 of the machine. Through the use of the rod 30, it creates an internal balance of forces, as a result of which mechanical stresses do not occur on the shaft 18 of the disc 3 with the mandrels 2 with the bearing in the machine frame 14, on the shaft 17 of the drive shaft 19 of the press 24 with the bearing in the housing 15. Therefore These items may be smaller in size, be cheaper to manufacture and more reliable to operate.
