Description

 The invention relates to a packaging technique for food products, and in particular to devices forming a dose and dispensing it into containers.

 The invention can be used in the meat, fish, dairy, fat and confectionery industries for volumetric group dosing of pasty food products, for example, meat or fish creams and pastes, processed cheeses, sour cream and confectionery products, while mainly in the packaging machines.

 A device for the packaging of fluid materials (ed. St. N 608706, class B 65 B 3/12), containing a metering cylinder with a piston and mounted at the outlet of it cork valve, made in the form of a housing and cork. A drain channel is formed in the crane body. Structurally, this device provides dosing of only one dose per cycle. For several doses per cycle, it is necessary to have the appropriate number of dispensers. This complicates the design of the dispenser and requires a sophisticated control system. In addition, when the dispenser stops beyond the permissible time according to sanitary standards, for example, when the packaging machines on which they are mounted fail, the dosed product can be damaged and sanitizer must be sanitized and completely disassembled.

 Similar disadvantages are possessed by devices for auth. N 870250, N 908658, N 1017595, N 1364534, N 1439037, MKI B 65 B 3/06, B 65 B 3/12, dispenser of automatic filling and packaging machine M6-ORK-1, M6-ORK-2 (see. 621.7984-139.2-52 Automatic filling and packing machine M6-ORK-1, M6-ORK-2. Technical specifications TU 27-32-2293-79 and Technical description and operating instructions for the automatic machine M6-ORK-1, M6-ORK-2 , Kapsukas, Lit.SSR, SKB RUA, 1985).

 For the prototype, you can take the volumetric group dispenser of pasty food products, consisting of the following main parts: the case with valves, the metering cylinder block, in which the disk jumpers and pistons of the plugs are mounted, the valve drive, the inlet manifold.

This dispenser has two significant disadvantages:
1. For short stops of the packaging machine, the dispenser must be stopped, as a result of which the product may stagnate in the latter.

 2. When starting the automatic packing machine to warm the dispenser with the product, it is necessary to put the pallet under the dispenser manually and manually change it when filling with the product.

 The aim of the invention is to eliminate the above disadvantages, namely improving operational properties by simplifying the process of preparing for work and eliminating stagnation of the product during short stops of the packaging machine.

 The goal is achieved by the fact that in the dispenser of the packaging machine containing a block of measuring cylinders, a housing with gates and gate drives, additional taps are mounted on the outlet channels behind the distribution gates, having longitudinal flats forming longitudinal channels associated with the outlet collector with the surface of the holes for the taps and having transverse channels; taps are mounted with the possibility of connecting the outlet channels from the distribution valve or with the outlet openings of the dispenser through the transverse channels of the crane, or with the outlet collector through the longitudinal channels in the crane.

 Figure 1 shows a General view of a filling and packaging machine with a metering device; figure 2 is a section aa in figure 1; figure 3 - view A; in FIG. 4 is a section BB of FIG. 3; figure 5 is a view along arrow G in figure 4; figure 6 - node I of figure 2.

 Volumetric group dispenser of pasty food products mainly for packaging machines has a housing 1 with valves 2 and valves 3, graduated cylinders 4, actuator 5 valves 2 and actuator 6 cranes 3.

 Measuring cylinders 4 are grouped into a single unit and are made in the form of a plate 7 with four through holes in which pistons 16 are installed in the form of sealing washers between the disk jumpers 14 with stops 21 on the central rods 15. The cranes 3 have longitudinal flats 12, forming longitudinal channels with the surface of the holes for the cranes connected to the outlet manifold 8 and having transverse channels 9, while the cranes 3 are mounted with the possibility of connecting the outlet channels 13 from the distribution valves or with the outlet openings 11 of the dispenser through the transverse channels 9 of the crane 3, or with a by-pass collector 8 through the longitudinal channels in the crane 3.

 The dispenser works as follows. The paste-like food product under pressure created by the pump, through the inlet manifold 17 enters the five cylindrical channels 18 of the housing 1. In each of these channels there are four cylindrical holes 10 through which the product enters the valves 2. The shutter 2 through the left channel 20 and the left hole 19 directs the product into the graduated cylinder 4. The product begins to move the piston 16 to the right, filling the resulting volume and displacing the product from the right side of the graduated cylinder 4 through the right hole 19, right channel 20, shutter 2, transverse channel 9 to ana 3 and an outlet opening 11 in the package. When the piston 16 reaches the stop 21, actuator 5 is activated, which has two working positions.

 In position No. 1, the volume of the graduated cylinder 4 was filled to the left of the piston (Fig. 6) and the product was squeezed to the right of the piston. Next, the product through the shutter 2 and the exhaust channel 13 enters the crane 3, which has two working positions. At the time when the piston 16 is moving, the valve 3 is in the operating position, in which the product through the transverse channels 9 of the valve 3 moves to the outlet 11 and through it into the package. When all the pistons 16 reach the stop 21 of the extreme right position, the actuator 6 is actuated. The actuator 6 turns the cranes 3 to the N 2 position (idle), at which the product passage to the outlet 11 is blocked and the channel 13 is connected with the longitudinal channel 12 of the crane 3. After this, the filled packages are replaced with empty ones. If any of the pistons 16 begins to pass the product, i.e. "bleeding" occurs, the product through the valve 2, the exhaust channel 13 and the longitudinal channel 12 of the crane 3 enters the manifold 8 and through it and the pipeline into the truck. After replacing the packages, actuators 5 and 6 are actuated, turning the valves 2 and 3, respectively. In this case, the cranes 3 by transverse channels 9 connect the channels 13 with the openings 11, the closures 2 close the volumes of the measuring cylinders 4, right from the pistons, with the channels 18 supplying the product, and the volumes of the measuring cylinders 4, left of the pistons, with the outlet holes 11.

 As a result, the piston 16 begins to move to the left under the pressure of the supplied product, displacing the product from the left part of the graduated cylinder 4. When the piston 16 reaches the stop 21, the valve 3 will turn the actuator 6 in the opposite position, and the packages filled will be replaced with empty ones. Next, the cycle repeats.

 In case of short stops of the packaging machine, the dispenser continues to work. At this point, the actuator 6 turns the cranes 3 to the “idle” position and the product through the bypass collector 8 enters the truck. Similarly, the dispenser works at the beginning of the shift when the dispenser and the packaging machine are started.

Thus, the proposed technical solution allows to improve operational properties, namely:
- carry out the warming up of the dispenser with hot water or hot steam when the additional valve is idle, when the waste water or steam is discharged from the machine through the dispenser by-pass collector into a separate container;
- start the machine and the dispenser with the supply of the product also when the additional valve is idle, when air is displaced from the dispenser through the manifold;
- flush and sanitize the internal cavities of the dispenser without removing the dispenser from the machine, since the disinfectant is discharged into a separate container through a separate collector;
- eliminate stagnation of the product in the dispenser during short-term stops of the packaging machine.
