Description

[Detailed Description of the Invention] The present invention relates to an apparatus for automatically cleaning carcasses of cows, pigs, etc.

Carcasses of cows, pigs, etc. immediately after being produced at a slaughterhouse must be washed and frozen for storage, but conventionally, workers used a fountain gun to clean the carcasses by hand.

For this reason, there are problems such as requiring a great deal of labor and the possibility that some parts cannot be sufficiently cleaned, and there has been a demand for automation of cleaning.

It is an object of the present invention to provide an automatic carcass washing apparatus that can meet the above-mentioned needs, and that can perform reliable washing with a relatively small amount of water and can be operated economically.

In order to achieve this purpose, the automatic carcass cleaning device of the present invention installs spouting pipes on both sides of the carcass conveyance path carried by the trolley, and makes these spouting pipes inclined in the front and rear direction of the carcass conveyance. The spout pipe is divided into a plurality of upper and lower parts at approximately regular intervals and arranged in a straight line, and each of the jet pipes is provided with nozzles at approximately regular intervals for spraying washing water toward the carcass. The upper and lower parts of the ejection pipe are separated and branched through electromagnetic valves, and the solenoid valves are configured to be sequentially and alternately opened and closed from the ejection pipe at the rear of the carcass conveyance direction to the ejection pipe at the front. It is something.

Hereinafter, an embodiment in which the present invention is applied to a pig carcass cleaning device will be described with reference to the drawings.

In the drawing, reference numeral 1 denotes a trolley rail, and a trolley hanger 2 suspended from this rail 1 is driven by a drive device 3, and a pair of left and right pig carcasses 4 are attached to the hanger 2.
, 4 are transported along the left and right transport paths 5, 5 in a suspended state.

There are four lines of ejection pipes 61 to 6 on both sides of the conveyance paths 5 and 50.
9 are installed respectively.

The ejection pipes are divided into three groups, 6□~63.64~66.67~69, and the ejection pipes of each group are inclined in the front and back direction of the carcass conveyance direction, and are divided into three parts: upper, middle, and lower. The ejection pipes 61 to 6. are arranged in a straight line. are each provided with several spray nozzles such that washing water is sprayed onto the carcass 4.4.

Further, a pump 9 is provided in the water pipe 8, nine branch pipes 101 to 109 are branched from the discharge side of this pump 9, and electromagnetic valves 111 to 119 are provided to these, respectively. Ejection pipes 61 to 69 of each series on the downstream side
are connected to each other.

The nozzle 7 injects water into a vertically long oblong cross section, and a set of jetting pipes 6□~63. They are arranged so that water can be sprayed without any gaps between them.

In order to prevent the carcasses 4, 4 from coming into contact with each other, a guide 12 is provided between the transport paths 5, 5, which is inclined vertically along the transport direction.

The electromagnetic valves 111 to 119 are connected to the carcass 4 by means of ties 7-, etc.
In synchronization with the conveying speed of
They are opened and closed sequentially and alternately from the one on the side to the one on the front side of the ejection pipe 69.

One side wall of the cleaning device is constructed of a building wall 13, and the other side wall is constructed of an accordion-type curtain 14, thereby preventing the cleaning water from scattering to the outside.

Next, the operation of the automatic cleaning device configured as above will be explained.

When the carcasses 4, 4 suspended from the hanger 2 and transported enter or approach the spraying range of washing water from the nozzle 7 of the masu spouting pipe 6□, the solenoid valve 11□ opens and the spouting pipe 6□
Washing water is sprayed from the nozzle I onto the carcasses 4, 4 to wash them.

When the carcass 4.4 comes out of the spraying range of washing water from the nozzle I of the spouting pipe 6□, the carcass 4, 4 enters the spraying range of washing water from the nozzle 7 of the next spouting pipe 6°.At this time, the solenoid valve 11□ closes and solenoid valve 112 opens.

Therefore, the injection of cleaning water from the nozzle I of the injection pipe 6□ is stopped, and the injection of cleaning water from the nozzle 7 of the injection pipe 6□ is performed.

Furthermore, when the carcass 4.4 exits the spraying range of washing water from the nozzle 7 of the spouting pipe 62 and enters the spraying range of washing water from the nozzle 7 of the spouting pipe 63, the solenoid valve 112 closes and the solenoid valve 11
3 opens, cleaning using the jet pipe 62 is completed, and the jet pipe 6
Washing is carried out using 3.

As described above, the first cleaning of the entire length of the carcasses 4, 4 in the vertical direction is completed, and then the second cleaning is performed in the same manner using the jetting pipes 64 to 66, and the jetting pipes 6□ to A third wash is performed using 69.

Therefore, according to this embodiment, the ejection pipes 61~63°64~
If the cleaning water spray range in the carcass transport direction by the nozzles 66 and 67 to 69 is made longer than the length of the carcasses 4, 4 in the transport direction, the washing water can be sprayed three times in the vertical direction while transporting the carcass 4, 4. Washing can be done separately three times before and after, ie, nine times in total.

Since the solenoid valves 11□ to 119 of the jet pipes 6□ to 69 are sequentially opened and closed for cleaning, only one of the solenoid valves 111 to 119 is always open during cleaning, and the others are closed. Therefore, there is no wasted water jet that does not hit the carcasses 4, 4, and the amount of water used is small.

Furthermore, since the amount of cleaning water used at the same time is small, even the pump 9 with a relatively small capacity can inject cleaning water with sufficient water pressure, resulting in low power consumption.

In this embodiment, when the carcass is small, it is preferable to suspend the carcass 4 from the hanger 2 via the auxiliary hanger 15, as shown on one side of FIG.

In the case of a beef carcass, the present invention can be applied in substantially the same manner as the case of a pig carcass in the above-described embodiment by using a single conveyance path and providing ejection pipes on both sides thereof.

Further, the direction of the inclination angle of the ejection pipe into nine divisions, the number of nozzles provided on the ejection pipe, and the interval can be changed as appropriate.

When a plurality of linearly arranged ejection pipes are provided in front and rear sets, it is preferable that the dividing portions of the different sets of ejection pipes are made different from each other as in the above embodiment.

The switching operation of a solenoid valve is not limited to a timer, but may also be a limit switch, a proximity switch, a phototube switch, etc. that are activated by the movement of a trolley hanger. It is also possible to keep the pump running all the time, and when there is no carcass in the washing device, all the solenoid valves are closed and the washing water is circulated accordingly.

As explained above, according to the present invention, the spout pipe is made into a straight line that is inclined in the front and back direction of carcass transportation and divided into multiple upper and lower parts, and the solenoid valves of these spout pipes are sequentially and alternately opened and closed. Washing water is sprayed from a provided nozzle, and while the carcass is being transported, it is divided into multiple parts in the vertical direction and washed, so the carcass can be washed automatically, and not only does it require less labor. The present invention has the effect of providing an automatic carcass washing device that can be operated economically with a small amount of washing water and power consumption, and that can spray washing water with sufficient water pressure and perform reliable washing.
