Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and in particular to a sausage processing production line. Background Technology

[0002] In the sausage production process, to ensure even heating, raw sausages are typically skewered onto hanging rods before being steamed or smoked in equipment such as steamers. After steaming or smoking, the sausages are separated from the hanging rods, and the empty rods are then transported to the front of the production line to continue skewering and steaming other raw sausages.

[0003] Currently, after a round of sausage steaming or smoking, the hanging rods are typically collected manually into a storage cart. The cart is then manually pushed back to the front of the production line. For the next round of sausage steaming or smoking, the hanging rods are removed one by one from the storage cart, and sausage strings are threaded onto them. The skewered rods are then placed onto a rack, which is pushed into the individual furnace. Once the sausages are cooked, the individual furnace releases steam for further cooling, thus achieving the desired steaming or smoking and cooling process. This production method requires a large area to store the individual furnaces, storage carts, and cooling carts. Furthermore, the rod sorting process is cumbersome, labor-intensive, and inefficient. In addition, each individual furnace consumes a large amount of steam, resulting in low steam utilization.

[0004] Therefore, it is necessary to provide a sausage processing production line that realizes automatic feeding and processing of sausages and automatic cyclic conveying on hanging rods, reducing manual labor intensity and energy consumption, while reducing equipment footprint and improving production efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a sausage processing production line that realizes automatic feeding and processing of sausages and automatic cyclic conveying of hanging rods, reducing manual labor intensity and energy consumption, while reducing the equipment footprint and improving production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a sausage processing production line, including a composite conveyor line, a loaded hanging rod conveyor line, a tunnel conveyor furnace, an unloaded hanging rod conveyor line, a rod feeding device, and a sausage feeding mechanism.

[0007] The composite conveyor line includes an upper conveyor layer and a lower conveyor layer. The upper conveyor layer and the lower conveyor layer have opposite conveying directions. The lower conveyor layer is provided with a delivery port adapted to an unloaded hanging rod.

[0008] The rod feeding device is located below the feeding port and is used to receive the empty hanging rod from the feeding port and pass the empty hanging rod through the sausage string to form a loaded hanging rod;

[0009] The sausage feeding mechanism is used to move the loaded hanging rod on the feeding rod device to the upper conveying layer;

[0010] The loaded hanging rod conveyor line is connected to the discharge end of the upper conveying layer and is used to convey the loaded hanging rod on the upper conveying layer to the feed end of the tunnel conveyor furnace.

[0011] The empty hanging rod conveyor line is used to transport the empty hanging rod at the discharge end of the tunnel conveyor furnace to the feed end of the lower conveyor layer.

[0012] As an improvement to the above solution, the composite conveyor line includes a first rotary conveyor line and a slide block. The first rotary conveyor line is provided with a lever, which moves with the first rotary conveyor line and drives the unloaded hanging rod on the slide block to slide in a preset direction.

[0013] As an improvement to the above solution, the slide includes a fixed base and a movable guide bar. The delivery port is disposed on the fixed base, and the movable guide bar is movably disposed on the delivery port so that the unloaded hanging rod slides over the movable guide bar or falls into the delivery port.

[0014] As an improvement to the above solution, a rod storage and splitting device is also included. The rod storage and splitting device includes a discharge rack, a first discharge hopper and a splitting mechanism. The discharge rack, the splitting mechanism and the first discharge hopper are arranged in sequence. The discharge rack is located below the feeding port and is used to arrange empty hanging rods and to make the empty hanging rods move sequentially toward the splitting mechanism.

[0015] The rod-splitting mechanism includes a first flipping drive mechanism and a rod-splitting piece. The rod-splitting piece is provided with a slot adapted to the unloaded hanging rod. The rod-splitting piece is flipped by the first flipping drive mechanism, and the unloaded hanging rod located at the discharge end of the discharge rack is inserted into the slot and falls into the first discharge hopper as the rod-splitting piece flips.

[0016] As an improvement to the above solution, the rod feeding device is located below the first hopper and includes a positioning bracket and a linear drive mechanism. The positioning bracket is provided with a positioning groove that is adapted to the unloaded hanging rod, and the linear drive mechanism is used to drive the positioning bracket to move back and forth to receive and transport the unloaded hanging rod.

[0017] As an improvement to the above solution, the movable guide bar is driven by the guide bar driving mechanism, and at least two delivery ports are arranged along the sliding direction of the unloaded hanging rod. A counting sensor is provided below each delivery port, and the counting sensor is electrically connected to the guide bar driving mechanism of the corresponding delivery port.

[0018] As an improvement to the above scheme, the discharge end of the lower conveying layer is provided with a collecting bucket.

[0019] As an improvement to the above solution, the split rod mechanism is set at the discharge end of the material discharge rack, the discharge end of the material discharge rack is inclined downward, and the arrangement direction of the unloaded hanging rods on the material discharge rack is the same as the moving direction of the unloaded hanging rods.

[0020] The slot includes an arc-shaped groove adapted to the unloaded hanging rod, and a flat portion tangent to the arc-shaped groove. When the first flipping drive mechanism drives the split rod to flip, the unloaded hanging rod located at the discharge end of the discharge rack contacts the flat portion first.

[0021] As an improvement to the above solution, the end of the loaded hanging rod conveyor line away from the upper conveyor layer is inclined downwards;

[0022] The empty hanging rod conveyor line includes a first empty hanging rod conveyor line and a second empty hanging rod conveyor line. The conveying direction of the first empty hanging rod conveyor line intersects the axial direction of the empty hanging rods on it. The second empty hanging rod conveyor line is located below the first empty hanging rod conveyor line and the lower conveyor layer. The conveying direction of the lower conveyor layer intersects the conveying direction of the second empty hanging rod conveyor line. The conveying direction of the second empty hanging rod conveyor line is the same as the axial direction of the empty hanging rods on it. A lifting mechanism is provided between the feed end of the lower conveyor layer and the second empty hanging rod conveyor line. The lifting mechanism is used to lift the empty hanging rods on the empty hanging rod conveyor line onto the slide block.

[0023] As an improvement to the above solution, the second unloaded hanging rod conveyor line includes a second rotary conveyor line and a third rotary conveyor line. Above the second rotary conveyor line is a second discharge hopper that connects to the discharge end of the first unloaded hanging rod conveyor line. The third rotary conveyor line is located directly below the loaded hanging rod conveyor line.

[0024] The lifting mechanism includes a second flipping drive mechanism and at least two lifting plates. The lifting plates are provided with hook grooves that are adapted to the unloaded hanging rods. The lifting plates are disposed at both ends of the third rotary conveyor line. The second flipping drive mechanism is used to drive the lifting plates to flip.

[0025] Implementing this invention has the following beneficial effects:

[0026] This invention discloses a sausage processing production line, which achieves automatic rod threading, continuous feeding of loaded rods into the tunnel conveyor furnace, and rod return by setting up a composite conveyor line, a loaded hanging rod conveyor line, a tunnel conveyor furnace, an unloaded hanging rod conveyor line, a rod feeding device, and a sausage feeding mechanism. While the sausage is being automatically fed and processed, the hanging rods are automatically conveyed in a cyclic manner, which improves production efficiency and steam utilization. In addition, the automatic conveying of the hanging rods in a cyclic manner eliminates the need for investment in individual furnaces, rod storage racks, and cooling racks, as well as the floor space they occupy.

[0027] The composite conveyor line uses an upper conveyor layer to transport loaded hanging rods and a lower conveyor layer to transport unloaded hanging rods. The upper and lower conveyor layers have opposite conveying directions, and the unloaded hanging rods are automatically recovered, making it convenient to string the unloaded hanging rods together. At the same time, the production equipment has a compact structure, which further saves the equipment's floor space.

[0028] The upper and lower conveyor layers are driven by the same rotary drive mechanism, which has low energy consumption and can help reduce production costs. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 10As shown, this invention discloses an embodiment of a sausage processing production line, including a composite conveyor line 1, a loaded hanging rod conveyor line 2, a tunnel conveyor furnace 3, and an unloaded hanging rod conveyor line 4. In this embodiment, a high-torque sausage conveyor line 5 is provided on the side of the composite conveyor line 1 for conveying strings of sausages.

[0041] The composite conveyor line 1 includes an upper conveyor layer a and a lower conveyor layer b located below the upper conveyor layer a, wherein the upper conveyor layer a and the lower conveyor layer b have opposite conveying directions.

[0042] Preferably, the upper conveying layer a and the lower conveying layer b of the composite conveyor line 1 are driven by the same rotary drive mechanism. In this embodiment, the composite conveyor line 1 includes a first rotary conveyor line 11 and a slide block 12. A first transport channel for accommodating sausage skewers is provided between the upper conveying layer a and the lower conveying layer b of the first rotary conveyor line 11. The slide block 12 is located below the lower conveying layer b, and a second transport channel for accommodating empty hanging rods is formed between the lower conveying layer b and the slide block 12. A lever 111 is provided on the first rotary conveyor line 11. The lever 111 moves with the first rotary conveyor line 11 and drives the empty hanging rods in the second transport channel to slide in a preset direction. The loaded hanging rod conveyor line 2 is connected to the discharge end of the upper conveying layer a and is used to transport the loaded hanging rods on the upper conveying layer a to the feed end of the tunnel conveyor furnace 3. The empty hanging rod conveyor line 4 is used to transport the empty hanging rods from the discharge end of the tunnel conveyor furnace 3 to the feed end of the second transport channel.

[0043] It should be noted that the loaded hanging rod in this embodiment is a hanging rod with sausage skewers on it, and the unloaded hanging rod is a hanging rod after it has been separated from the sausage skewers.

[0044] The tunnel conveyor 3 can be a sausage processing device, such as a steaming oven or a smoking oven, but is not limited to these. The discharge end of the tunnel conveyor 3 is equipped with a cutting mechanism for separating the sausages from the carrying rod.

[0045] In this embodiment, a slide 12 is installed below the first rotary conveyor line 11, and a lever 111 is installed on the first rotary conveyor line 11. A first transport channel is formed between the upper conveying layer a and the lower conveying layer b of the first rotary conveyor line 11. A loaded hanging rod is erected on the upper conveying layer a of the composite conveyor line 1, and sausage strings on the loaded hanging rod are transported through the first transport channel. At the same time, a second transport channel is formed between the lower conveying layer b and the slide 12. The lever 111 of the lower conveying layer b causes the empty hanging rod in the second transport channel to move in the opposite direction. The discharge end of the loaded hanging rod in the upper conveying layer a is the feed end of the empty hanging rod in the lower conveying layer b. The transport of loaded hanging rods and the recovery of empty hanging rods can be achieved through a single rotary conveyor line, which is convenient for empty hanging rods. The sausage skewers are threaded through the rod again for the next round of sausage processing. The loaded hanging rods of the upper conveyor layer a are transported to the tunnel conveyor furnace 3 for processing via a loaded hanging rod conveyor line 2 that connects to the discharge end of the upper conveyor layer a. The processed sausage skewers are separated from the hanging rods at the discharge end of the tunnel conveyor furnace 3. The unloaded hanging rod conveyor line 4 transports the unloaded hanging rods from the discharge end of the tunnel conveyor furnace 3 to the second transport channel of the composite conveyor line 1. The paddle 111 on the first rotary conveyor line 11 drives the unloaded hanging rods on the slide block 12 in the opposite direction to the transport direction of the loaded hanging rods on the upper conveyor layer a. The unloaded hanging rods are automatically recovered. This production equipment has a compact structure, low energy consumption, and can help improve production efficiency and reduce production costs.

[0046] To improve the production efficiency of sausage skewering and feeding, this embodiment is provided with at least two sets of sausage feeding mechanisms 61 along the conveying direction of the upper conveying layer a, as well as a rod storage and distribution device 7 and a rod feeding device 8 corresponding to the sausage feeding mechanism 61. The rod feeding device 8 is used to pass an empty hanging rod through the sausage skewer on the high-torsion sausage conveyor line 5 to form a loaded hanging rod. The sausage feeding mechanism 61 is used to transfer the loaded hanging rod passing through the sausage skewer on the rod feeding device 8 to the upper conveying layer a of the composite conveyor line 1.

[0047] Combination Figure 4 In this embodiment, the slide 12 includes a fixed seat 121 and a movable guide bar 122. The fixed seat 121 is provided with a delivery port 123 adapted to the unloaded hanging rod. The movable guide bar 122 is movably disposed in the delivery port 123 so that the unloaded hanging rod slides over the movable guide bar 122 or falls into the delivery port 123.

[0048] The rod storage and distribution device 7 and the rod delivery device 8 are both located below the delivery port 123.

[0049] Combination Figure 5 and Figure 6The rod storage and distribution device 7 specifically includes a discharge rack 71, a first discharge hopper 72, and a rod distribution mechanism 73. The discharge rack 71, the rod distribution mechanism 73, and the first discharge hopper 72 are arranged sequentially. The discharge rack 71 is located below the feeding port 123 or the rod collecting hopper and is used to arrange unloaded rods and to move the unloaded rods sequentially toward the rod distribution mechanism 73.

[0050] In this embodiment, the lever-splitting mechanism 73 is disposed at the discharge end of the discharge rack 71. Preferably, the discharge end of the discharge rack 71 is inclined downwards. The arrangement direction of the unloaded hanging rods on the discharge rack 71 is the same as the direction of movement of the unloaded hanging rods. In this embodiment, the discharge rack 71 moves towards the discharge end by pushing against each other under its own weight, until the unloaded hanging rods at the discharge end abut against the lever-splitting mechanism 73.

[0051] The rod-splitting mechanism 73 specifically includes a first flipping drive mechanism and a rod-splitting piece. The rod-splitting piece is provided with a slot adapted to the unloaded hanging rod. The rod-splitting piece is flipped by the first flipping drive mechanism. The unloaded hanging rod located at the discharge end of the discharge rack 71 is inserted into the slot and falls into the first discharge hopper 72 as the rod-splitting piece flips.

[0052] The unloaded hanging rod is cylindrical and can roll smoothly on the inclined discharge rack 71. The slot includes an arc-shaped groove 731 adapted to the unloaded hanging rod and a flat portion 732 tangent to the arc-shaped groove 731. When the first flipping drive mechanism drives the rod segment to flip, the unloaded hanging rod at the discharge end of the discharge rack 71 contacts the flat portion 732 first. The arc-shaped groove 731 is preferably a semi-cylindrical surface. When the first flipping drive mechanism drives the rod segment to flip, the unloaded hanging rod at the discharge end contacts the flat portion 732 first. Under the guidance of the flat portion, the unloaded hanging rod smoothly falls into the slot, and after the rod segment flips at a certain angle, the unloaded hanging rod slides from the flat portion 732 into the discharge hopper.

[0053] Preferably, the segment is provided with two or more slots. When the first flipping drive mechanism 31 and the linear drive mechanism work together, the flipping stroke of the segment can be reduced, thereby reducing the flipping speed, so that the unloaded hanging rod can be inserted into the slot more smoothly and orderly.

[0054] The first tilting drive mechanism includes a geared motor and a first rotating shaft connected to the power output end of the geared motor. The split rods are arranged in at least two configurations, and the split rods are arranged axially along the first rotating shaft to keep the unloaded hanging rod lifted by the split rods balanced.

[0055] The rod feeding device 8 is located below the first hopper 72 and includes a positioning bracket 81 and a linear drive mechanism 82. The positioning bracket 81 is provided with a positioning groove adapted to the unloaded hanging rod. The linear drive mechanism 82 is used to drive the positioning bracket 81 to reciprocate so as to receive and transport the unloaded hanging rod.

[0056] The linear drive mechanism 82 includes a transmission belt 821, a guide rail 822, and a slider 823 connected to the transmission belt 821. The slider 823 is in sliding engagement with the guide rail, and one end of the positioning bracket 81 is connected to the slider 823.

[0057] The direction of reciprocating movement of the positioning bracket 81 is parallel to the axial direction of the unloaded hanging rod located in the positioning groove.

[0058] In this embodiment, the positioning bracket 81 is provided with two oppositely arranged material support blocks 811, and the positioning groove is provided on the material support blocks 811. The positioning bracket 81 is provided with a positioning sensor. When the automatic rod feeding mechanism senses that an empty hanging rod has fallen into the positioning groove, it drives the rod feeding reducer 824 connected to the transmission belt 821 to move. The transmission belt 821 drives the slider 823 on the guide rail 822 to send the positioning bracket 81 out of the through-hole.

[0059] The cross-sectional area of ​​the positioning bracket 81 at the end away from the slider 823 gradually decreases so that the sausage skewer can pass through smoothly.

[0060] Accordingly, to improve the efficiency of the empty hanging rod return and further enhance the sausage feeding efficiency, at least two feeding ports 123 are provided along the sliding direction of the empty hanging rod, and a counting sensor (not shown in the figure) is provided below each feeding port 123. Combined with... Figure 7 The movable guide bar 122 is driven by the guide bar driving mechanism 124, and the counting sensor is electrically connected to the guide bar driving mechanism 124 corresponding to the delivery port 123.

[0061] The guide bar drive mechanism 124 can linearly drive the movable guide bar 122 to translate and open the delivery port 123, allowing the unloaded hanging rod to fall into the delivery port 123.

[0062] The guide bar driving mechanism 124 in this embodiment includes a third rotating shaft and a third flipping driving mechanism. The movable guide bars 122 are arranged in at least two groups on the third rotating shaft, and the movable guide bars 122 are connected to the third rotating shaft through connecting arms thereon.

[0063] When the lever 111 drives the empty hanging rod to slide near a dispensing port 123, and the counting sensor detects that the number of items dispensed at the current dispensing port 123 has reached a preset value, the third flipping drive mechanism keeps the movable guide bar 122 flush with the top surface of the fixed base 121, so that the empty hanging rod can smoothly pass through the current dispensing port 123 via the movable guide bar 122. The lever 111 continues to drive the empty hanging rod forward to the next dispensing port 123. When the lever 111 drives the empty hanging rod to slide near a dispensing port 123, and the counting sensor detects that the number of items dispensed at the current dispensing port 123 has not reached a preset value, the third flipping drive mechanism drives the movable guide bar 122 to flip and open the current dispensing port 123, and the empty hanging rod falls into the dispensing port 123. After the preset number is reached, the third flipping drive mechanism drives the movable guide bar 122 to reset so that the empty hanging rod can continue to pass.

[0064] In addition, the discharge end of the second transport channel in this embodiment is also provided with a rod collection hopper 9. When the number of rods in all the feeding ports 123 reaches the preset value, the empty rods are finally collected in the rod collection hopper 9.

[0065] This embodiment achieves automatic rod threading, feeding, rod return, and rod collection by setting up a composite conveyor line 1, a loaded hanging rod conveyor line 2, a tunnel conveyor furnace 3, an unloaded hanging rod conveyor line 4, a rod feeding device 8, a sausage feeding mechanism 6, and a rod storage and distribution device 7. While the sausage is being automatically fed and processed, the hanging rods are automatically conveyed in a cyclical manner, resulting in high production efficiency.

[0066] In this embodiment, the tunnel conveyor furnace 3 is equipped with a circulating conveyor line (not shown in the figure), which uses chain drive. Raw sausages enter the tunnel conveyor furnace 3 and directly undergo the entire process of steaming, air drying, smoking, and cooling, resulting in cooked sausages. The circulating conveyor line ascends and descends in an S-shape within the furnace cavity, ensuring more uniform heating of the sausage skewers. The inlet and outlet ends of the tunnel conveyor furnace 3 are relatively low. To transfer the loaded hanging rod from the upper conveyor layer a to the lower inlet end of the tunnel conveyor furnace 3, the end of the loaded hanging rod conveyor line 2 away from the upper conveyor layer a is inclined downwards.

[0067] Among them, combined Figure 8 The loaded hanging rod conveyor line 2 includes at least two sets of parallel and synchronously operating fourth rotary conveyor lines 21. Each fourth rotary conveyor line 21 is equipped with baffles 211. Loaded hanging rods located at the discharge end of the upper conveying layer a slide down onto the fourth rotary conveyor line 21 and abut against the baffles 211. The baffles 211 ensure that the loaded hanging rods on the inclined loaded hanging rod conveyor line 2 are conveyed at a specific interval.

[0068] In this embodiment, at least two first rotary conveyor lines 11 and four rotary conveyor lines 21 are provided. Each first rotary conveyor line 11 moves synchronously, and each fourth rotary conveyor line 21 moves synchronously. During transportation, the loaded hanging rod spans across two first rotary conveyor lines 11 or two fourth rotary conveyor lines 21.

[0069] Preferably, both the first rotary conveyor line 11 and the fourth rotary conveyor line 21 are conveyor chains and are driven by the same drive sprocket, which can further reduce energy consumption. In order to ensure that the first transport channel has sufficient space to accommodate the sausage skewers threaded on the carrying rod, this embodiment has a tensioning wheel fitted inside the first rotary conveyor line 11, and the tensioning wheel is located below the drive sprocket.

[0070] In this embodiment, an empty hanging pole transfer mechanism 62 is provided between the tunnel conveyor furnace 3 and the empty hanging pole conveyor line 4.

[0071] In this embodiment, both the sausage feeding mechanism 61 and the empty hanging rod transfer mechanism 62 can be robotic arms with hanging rod grippers.

[0072] To avoid interference between the unloaded hanging rod conveyor line 4 and the downwardly inclined loaded hanging rod conveyor line 2, the unloaded hanging rod conveyor line 4 includes a first unloaded hanging rod conveyor line 41 and a second unloaded hanging rod conveyor line 42. The conveying direction of the first unloaded hanging rod conveyor line 41 intersects the axial direction of the unloaded hanging rods on it. The second unloaded hanging rod conveyor line 42 is located below the first unloaded hanging rod conveyor line 41 and the lower conveying layer b. The conveying direction of the lower conveying layer b intersects the conveying direction of the second unloaded hanging rod conveyor line 42. The conveying direction of the second unloaded hanging rod conveyor line 42 is the same as the axial direction of the unloaded hanging rods on it.

[0073] Among them, combined Figure 9 A lifting mechanism 10 is provided between the lower conveying layer b and the feeding end of the second unloaded hanging rod conveying line 42. The lifting mechanism 10 includes a second flipping drive mechanism 101, a second rotating shaft 102, and at least two lifting plates 103 provided on the second rotating shaft 102. The lifting plates 103 are provided with hook grooves adapted to the unloaded hanging rod. The second flipping drive mechanism 101 is used to drive the lifting plates 103 on the second rotating shaft 102 to flip.

[0074] Specifically, in combination Figure 10The second unloaded hanging rod conveyor line 42 includes a second rotary conveyor line 421 and a third rotary conveyor line 422. A second discharge hopper, which connects to the discharge end of the first unloaded hanging rod conveyor line 41, is located above the second rotary conveyor line 421. The third rotary conveyor line 422 is located directly below the loaded hanging rod conveyor line 2. Lifting plates 103 are located at both ends of the third rotary conveyor line 422. The length of the unloaded hanging rod is greater than the conveying length of the third rotary conveyor line 422. During the process of the unloaded hanging rod being conveyed from the second rotary conveyor line 421 to the third rotary conveyor line 422, it passes through the groove of the lifting plate 103 and extends to both ends of the third rotary conveyor line 422. When the lifting plate 103 flips, it lifts the unloaded hanging rod onto the slide block 12.

[0075] The lifting mechanism 10 lifts the empty hanging rods on the empty hanging rod conveyor line 4 onto the slide block 12. On the one hand, this reduces the distance requirement between the empty hanging rod conveyor layer and the loaded hanging rod conveyor layer, thus reducing the cost of the composite conveyor line 1. On the other hand, it prevents the empty hanging rods on the empty hanging rod conveyor line 4 from puncturing or knocking down the sausage strings on the loaded hanging rod conveyor line 2. The arrangement of the empty hanging rod conveyor line 4 and the lifting mechanism 10 facilitates the spatial layout of the equipment and saves space and equipment costs.

[0076] To achieve directional and stable transmission of loaded and unloaded hanging poles, this embodiment provides guide plates on both sides of the first transport channel and the second transport channel, as well as on both sides of the top of the second rotary conveyor line 421 and the fourth rotary conveyor line 21.

[0077] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
