LT6172B - Automatic packaging line of gloove products - Google Patents

Abstract

The automatic packaging machinery for finger type products is designed to collect randomly falling products on a transporter of the packaging machinery, where all the group of finger type products is transferred onto a sectional lifting mechanism by pushing them from behind with minimal impact to each product. Sectional lifting mechanism transfers groups of finger type products into openings of a frame with configuration of package matrix, without any impact on individual finger type products. Further the frame filled with finger type products is transferred via food grade polymer belt transporter; therefore surfaces of finger type products are not adversely affected during discharge from the frame into a nest package. In order to allow packaging of different size products, the technological configuration of the frame is same as configuration of a nest package block. Number of rows in a layer is formed on a threshold system of the lifting mechanism, while required number of layers is formed by repeated layer formation in the frame nest, without changing the position of the frame. In order to ensure a minimal overload of the package nest a length of each product is measured; products with wrong dimensions are eliminated. In order to achieve maximum packaging efficiency, packaging process is separated into few different packaging operations. Side sensors are integrated into technological frames, which are loaded, one by one, into the machinery by an operator, after the machinery is prepared for exploitation. A sensor identification system is integrated into a reception station of the machinery. This system assures that only appropriate and correctly oriented frames are accepted by the machinery. Finger type product grouping systems at each flow line have finger type product counters and group traps are configured to maintain 40-60 mm gap between last finger type product and its group. Such finger type product group is transported up to the support.

Description

The invention relates to the packaging of food industry products and other finger-shaped articles.

Currently known U.S. firms F.R. The sausage packaging lines manufactured by Drake Company are described in US 2013/0105035 A1, US 2013/0092510 A1, US 2010/0133065 A1, US 2005/0249577 A1, of which US 2010/0133065 A1 can be considered as the closest analogue.

The packaged sausages in the lines described in these patents are chaotically thrown into the line stacker; from the bottom of the store, a conveyor with transverse tabs “carries” sausages to the orientation of the sausages in the conveyor slots of the machine. With mechanical brushes, the sausages are oriented to the nests. Non-nesting sausages are returned to the hopper. The sausage slots are filled by hand and strips of sausages are formed in the slots. From the strips of sausages in the slots, the sausages are mechanically moved to the slots of the package.

These lines have the following disadvantages:

- sausage casings are susceptible to repeated mechanical stress;

- this line can only pack in two column packing slots;

- The line cannot pack in multiple layers;

- packing only of fixed gauges, the dimensions of which are determined by the design of the line;

- Line packing performance by only one-third meets today's sausage production performance of 30 sausages per second;

- the line does not have a length control of the sausages, which would allow the formation of minimum overweight packaging slots.

The proposed packaging line for finger-shaped products does not have the disadvantages mentioned above.

The proposed line has the following advantages:

- the wrappings of packaged products (eg sausages) are not damaged;

- maintaining a constant weight of packages with a minimum excess weight in the package;

- packing into packing matrices of any configuration having any number of columns in the packing matrix;

- It is possible to pack products of any size (eg sausages);

- products (eg sausages) are placed in the slots of the package in the desired order according to the number of layers, the number of sausages in each layer, the number of rows of sausages in each layer;

- products (eg sausages) are packed in a very compact manner in a packing box;

- the packaging capacity corresponds to the production capacity.

Operation of packing line

The operation of the packaging line is illustrated in FIG. 2.

The sausages are packaged in conveyors 1, 2 and 3. The sausages transported by each conveyor are arranged along the conveyor, two adjacent to each other.

The dividers 4, 5 and 6 form the streams of sausages with the sausages arranged one on the other on conveyors 7, 8, 9, 10, 11 and 12. When transporting the sausages on conveyors 7, 8, 9, 10, 11 and 12, the length of each sausage is evaluated. . Evaluation and removal of unsuitable sausages is carried out at nodes 13, 14 and 15. Evaluation is performed by optical measuring systems located at nodes 13, 14 and 15.

Suitable sausages are placed on grouping conveyors 16, 17, 18, 19, 20 and 21 by stacking them across the bands of the grouping conveyor. There is a conveyor for each sausage flow. Above each grouping conveyor there is a grouping unit 22, 23, 24, 25, 26 and 27. The grouping unit consists of a sausage counter, a trap positioned, assembling! the right group of sticks.

The initial fill of the line with empty frames is executed at post 28. It evaluates the frame provided by the operator, determines whether it is the frame of the required configuration and whether it is properly oriented. A suitable frame is pushed by an empty frame positioner onto the conveyor 30. This conveyor provides empty frames for each frame fill line serving one of the sausage flows. The empty frame 32 is positioned by the guiding gates 33, 34, 35, 36, 37 and 38 at the respective fill line of the frames. The empty frames (32) positioned along the respective frame filling line are placed on the frame filling line by the empty frame positioning devices 39, 40, 41, 42, 43 and 44. Thus, all frame filling sausage lines are filled with empty frames 45, 46, 47, 48, 49 and 50, which are positioned in a single row of the frame during their filling.

The filling of the frames is carried out as follows: the grouping of sausages by grouping conveyors enters their stops 51, 52, 53, 54, 55 and 56. Each station consists of guided barriers for stopping each group and pushers pushing the groups of sausages into the guides.

The sausage-filled guides on the elevator-operated shutter are unloaded into the rows of frames at the filling stations 57, 58, 59, 60, 61 and 62. The interaction between the conveyor and the lift mechanism is adjusted so that the displacement effect on each product is minimal. The lift-threshold mechanism for moving the glove product groups to the frame having the package matrix configuration is so adjusted that the glove product groups are moved into the frame windows without the force of the individual glove product being applied to all surfaces of the product group. The sausage-filled frames 69, 74, 73, 75, 77, 79, and 80 with positioners 63, 64, 65, 66, 67, and 68 are placed on the filled-frame conveyor 82. The technology frame configuration is identical to that of the blister pack unit, what size glove products. The organized delivery of the filled frames 69, 71, 73, 75, 77, 79 and 80 by the conveyor 82 j is secured by guiding barriers 70, 72, 74, 76, 78 and 81. The filled sausage frame from the conveyor 82 by positioner 83 having a filled frame locking node 84 is provided to a frame unloading station 86. The number of rows per layer is formed on the threshold system of the lift mechanism, the glove product groups are formed by the size of the row layer, the entire socket layer having one or more product rows is formed on the elevator mechanism, frame socket repeatedly, placing layers without frame positioning.

The unloading frame is positioned on a control damper located above the package. Unloading of the frame takes place at the unloading station 86 by opening the valve and pushing the existing sausages out of each slot into the packaging slots. In order to ensure maximum packing speed, the packing process is divided into separate packing operations: 1) grouping, 2) placing groups into a lift-threshold mechanism, 3) moving groups into sockets of the technology frame, 4) uniform technology frames in each of six or more streams 5) placing the glove product-filled frame above the packaging matrix; 6) placing the glove product from the process frame into the packaging matrix slots.

The empty frame is returned by positioner 83 to the conveyor 29.

The unloading frame can be rotated 90 ° by means of the mechanism 85.

Technological frames that the operator puts into the line one at a time after line preparation for packing have side sensors, and the line technology frame pickup station has a scanning system for these sensors, which prevents an inappropriate or slightly repaired frame from entering the line.

On the line, the acceptance, sorting and packaging of sausages takes place in automatic mode with the automatic control system (control cabinets 87, 88, 89 and 90 and control panel 91).

Line re-alignment is accomplished by replacing the frames (Frame Containers 93, 94, and 95) and replacing the reordering parts (Containers 92 and 96).

The glove product grouping systems on each flow, with glove product counters and group traps, are formed such that the last group of glove products is 40-60 mm behind the entire group, thereby transporting the formed glove product group to the supports, locking the group out onto the supports. the sliders of the lift-threshold mechanism, and the lagging glove product, when hit by a suspended group, would compact it while providing better group formation.
