Description

Technical Field

[0001] The present invention relates to a cleaning device for meat and bodies of pigs, cows, etc., and particularly to a cleaning brush and a jig attached to the cleaning device.

Background Art

[0002] In meat processing plants that process pigs, cows, etc. into meat products, a series of lines are used to process from the slaughter process of pigs and cows to the shipment of the carcasses as products. In this processing line, first, a process of cutting a female knife into the throat of the body to bleed is required. Bleeding is important as it affects the quality of the meat. As a method, it is generally practiced to hang the body upside down and let the blood flow down and be released from the part where the female knife is inserted.

[0003] This bleeding is carried out while transporting the body on a trolley suspended using a hook on an overhead rail line. However, in the bleeding process, there was a problem that in addition to blood adhering to the surface of the body, dirt such as feces and urine remained attached.

[0004] In the cleaning of the body, conventionally, since an operator manually carried out the cleaning one by one using a hose with a nozzle that sprays high-pressure cleaning water, it was necessary to temporarily stop the line in the cleaning process. Even when simply spraying high-pressure cleaning water, it was insufficient to clean each part evenly, and there was a problem of low productivity in terms of hygiene and the large amount of cleaning water used.

[0005] Therefore, for example, as disclosed in Patent Document 1, a device has been proposed that cleans by bringing a pair of rotating cleaning brushes arranged in parallel into sliding contact with the cut surface of a meat block. Also, a structure has been proposed in which a pair of cleaning brushes are rotatably arranged at a position sandwiching the path line of the overhead rail in a cleaning chamber, a plurality of hard nylon ropes are arranged radially with respect to the rotating shaft on this cleaning brush, and a plurality of stages are provided in the vertical direction of the rotating body (see Patent Document 2). Incidentally, the material of the cleaning brush is not particularly mentioned in Patent Document 1.

[0006] Furthermore, there were methods that involved drilling spiral holes in an iron pipe, threading a safety rope through them, and rotating the pipe while the rope was wrapped around the body, causing the bumps on the rope to rub against the body, or methods that replaced the safety rope with a ring of rubber or synthetic resin blades that rotated to knock off the dirt. However, these types had problems: the rope did not make full contact with the body, resulting in a weak cleaning effect; the blades were prone to breaking; and the blades could not be replaced without disassembling the device.

[0007] [Patent Document 1] Japanese Utility Model Publication No. 57-158286 [Patent Document 2] Japanese Utility Model Publication No. 63-101087 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, the device described in Patent Document 1 requires the entire cleaning brush to be replaced even if only a part of it is worn out, which is not only cost-ineffective but also makes it difficult to separate for disposal. Furthermore, devices using hard nylon rope or safety rope cannot thoroughly and carefully clean the carcass, and there is a problem that the carcass surface may be hit too hard, potentially damaging the flesh.

[0009] In view of the problems of the prior art described above, this invention aims to provide a brush structure for washing meat and body that is soft and delicate to the body surface, exhibits thorough and high cleaning power, has a long lifespan, is easy to replace the brush, and is easy to separate when discarded. [Means for solving the problem]

[0010] Therefore, the first feature of the present invention is that the meat and body washing brush jig is composed of a brush holding plate, a lid that is joined to the holding plate, and a nylon thread bundle, and the nylon thread bundle is made by bundling multiple nylon threads having a predetermined length and thickness, bending them approximately in the middle, and clamping and fixing this bent portion between the holding plate and the lid. The second feature is that the device consists of a brush-holding plate with at least two grooves, a lid that is joined to the holding plate, and a nylon thread bundle, wherein the nylon thread bundle is made by bundling multiple nylon threads of a predetermined length and thickness, tying them together at approximately the center, and bending the whole into an approximately U-shape, and this bent portion is detachably fitted into the grooves of the holding plate, and the nylon thread bundle is clamped and fixed by the lid so that it protrudes radially from the pipe through through holes drilled in the pipe, which is provided along the axial direction of the rotation axis of the meat and body washing device. The third characteristic is that the nylon thread is used as fishing line. [Effects of the Invention]

[0011] As this invention is configured as described above, it has the following excellent effects. (1) A nylon thread band is made by cutting fishing line to a certain length, bundling several strands together, and bending the central part into a roughly U-shape before tying them together. It will not come off even when swung around or hit against the body. (2) Fishing line is strong, has a long lifespan, is gentle on the body surface, and can provide delicate and thorough cleaning without damaging the skin surface. (3) When replacing the brushes, only the worn-out parts of the brush fixture need to be replaced. It is cost-effective. (4) Brush replacement is a simple operation that only requires tightening and loosening the bolts and nuts on the brush jig, making it highly efficient. (5) The nylon bundle can be easily separated from the brush jig, making it easy to separate when disposing of the brushes. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described based on the examples shown in the drawings. For the sake of simplicity of explanation, the meat and body of pigs, cows, etc. to be cleaned are simply described as body B.

Example

[0014] Hereinafter, the features of the present invention will be specifically described based on the examples shown in the drawings. First, the body cleaning device C in which the cleaning brush of the present invention is used will be described based on FIGS. 7 to 8. In the meat processing line, an overhead rail L is arranged from the slaughterhouse to the end, and the carcass B is suspended and conveyed by a trolley with a hanger that slides on this overhead rail L. In the slaughterhouse, the carcass B is put into a state of suspended animation and then its throat is cut with a knife for bloodletting. For this bloodletting process, as shown in Fig. 7, the carcass B is suspended upside down on the trolley and conveyed while discharging blood. And a carcass washing device C is arranged in the middle of the processing line so as to be located after the bloodletting process step.

[0015] This carcass washing device C is a box-shaped body that forms a washing chamber W inside, and the overhead rail L is arranged on its upper part, and has a structure that allows a trolley suspending the carcass B to pass through. Fig. 7 is a front view showing the internal structure, Fig. 8(a) is a plan view of the carcass washing device C seen from above, Fig. 8(a) is a plan view of the carcass washing device C seen from above, and (b) is a side view.

[0016] Inside the washing chamber W, a pair of washing brushes 7, 8 are rotatably arranged at positions sandwiching the pass line of the overhead rail L. These washing brushes 7, 8 are provided around a pair of rotating shaft bodies S1, S2, and the rotating shaft bodies S1, S2 are supported by motors 11, 12 provided on the upper part of the washing device C.

[0017] As shown in Figs. 5 to 6, the washing brushes 7, 8 are arranged radially on the side surfaces of the rotating shaft bodies S1, S2 following long plate-shaped liners 9, 10 extending radially, and the brush fixtures 1 are installed on the long plate-shaped liner 9 and the long plate-shaped liner 10 at different height positions and evenly arranged on each rotating shaft body S1, S2. Then, by the motors 11, 12, the respective rotating shaft bodies S1, S2 are driven to rotate in opposite directions to each other. [[ID=1十三]]

[0018] Furthermore, inside the washing chamber W, a plurality of washing nozzles 13 for injecting washing water are provided at appropriate positions. A pipe (not shown) for supplying washing water from the outside is connected to this washing nozzle 13, and washing water is injected while the carcass B is inside the washing chamber W.

[0019] The operation of the cleaning brushes 7, 8 and the cleaning nozzle 13 is controlled by drive-on / off switches and drive-off / discharge switches provided on the elevated rail L at the inlet and outlet sides of the cleaning chamber W. These inlet / discharge switches are activated each time a trolley (not shown) traveling on the elevated rail L engages with them. That is, when the cart B enters the cleaning chamber W, solenoid valves (not shown) provided in the piping to the motors 11, 12 and the cleaning nozzle 13 are activated, causing the rotating shafts S1, S2 to rotate and cleaning water to be sprayed from the cleaning nozzle 13. Also, when the trolley engages with the discharge switch, the power supply to the motors 11, 12 is stopped and the spraying of cleaning water stops.

[0020] In the above configuration, when the carcass B travels along the elevated rail L on the trolley and enters the washing chamber W, the rotating shafts S1 and S2 begin to rotate, and washing water is sprayed from the washing nozzle 13. At this time, since the rotation directions of the rotating shafts S1 and S2 are opposite to each other, the carcass B moves while rotating. During this time, the washing brushes 7 and 8 wipe away blood and feces and urine adhering to the surface of the carcass B due to the rotation of the rotating shafts S1 and S2. In addition, this waste is washed away by the spray of washing water.

[0021] As shown in Figures 1 to 4, the meat and body washing brush jig 1 according to the present invention consists of a substantially rectangular brush holding plate 2 with at least two grooves 3a, a lid 3 that closes the holding plate 2, and a nylon thread bundle 4. The nylon thread bundle 4 is made by bundling multiple nylon threads of a predetermined length and thickness, securing the approximate center with a cable tie 5, and bending the entire bundle into a substantially U-shape. This bent portion is detachably fitted into the grooves 2a of the holding plate 2. The number of grooves 2a can be arbitrarily changed according to the design, as long as there are at least two even grooves. In this embodiment, four grooves are provided on one brush holding plate 2, allowing two bundles of nylon thread bundle 4 to be attached.

[0022] The lid 3 and the liners 9 and 10 are fastened and clamped together with bolts 6 and nuts 6a so that the nylon thread bundles 4 protrude radially from the rotating shafts S1 and S2 through through holes 9a and 10a provided along the length direction of the liners 9 and 10 of the rotating shafts S1 and S2 of the cleaning device.

[0023] Here, it is preferable to use fishing line for the nylon thread bundle 4. The nylon thread bundle 4 is made by cutting fishing line to a certain length (about 150 pieces), bundling them together, bending the central part into a roughly U-shape, and tying them together. Even when swung around, it will not come off when it hits the carcass B. In addition, fishing line has high strength and a long lifespan, and it is gentle on the surface of the carcass B, allowing for thorough cleaning without damaging the skin surface of the carcass B. Furthermore, brush replacement is a simple operation that only requires removing the worn bolts 6 and nuts 6a of the jig. It is economical as it can be directly attached to existing cleaning machines.

[0024] The fishing line used in this embodiment is made of nylon and conforms to the "No. 1 = standard diameter 0.165 mm" standard set by the Japan Fishing Tackle Manufacturers Association. While nylon, fluorocarbon, polyester, etc., are used as materials for nylon fishing lines, for convenience, this invention refers to all of these materials together as "nylon fishing line." Furthermore, it goes without saying that the line size (thickness) and strength are not particularly limited as long as they can achieve the same desired effect as this invention, regardless of the material.
