Description

Technology Field

[0001] The present invention relates to a precision weighing device for a fermented feed wrapping packaging machine, and more specifically, to a precision weighing device for a fermented feed wrapping packaging machine that can discharge a precise amount of fermented feed to the outside by having a load cell accurately measure the weight of the fermented feed without interference from vibrations occurring during the packaging process when the fermented feed is introduced into the weighing guide section. Background Technology

[0003] Generally, fermented total mixed feed (TMF), which is used as feed for livestock such as dairy cows, Hanwoo, and beef cattle, consists of main ingredients such as forage, grain feed, and other additives. It contains about 35–40% moisture and a large amount of dried fibrous forage (approximately 30%), so there is a large variation in volume even at the same weight depending on the weight of the feed.

[0004] Recently, methods and devices have been developed and are being used to compress fermented feed and wrap it with a stretch film, such as vinyl, to promote fermentation, enable long-term storage, and maintain the fermented state.

[0005] These conventional feed wrapping devices typically use a method of measuring the weight of the bale on a conveyor or transferring the bale to a weighing scale using a conveying mechanism when packaging and discharging the feed into bales.

[0006] However, these conventional feed wrapping devices have the problem of prolonging the bale manufacturing process because the process of measuring weight is added during the process of moving the packaged bales for storage or use. Furthermore, if the weight of the feed is measured during compression packaging, the bales cannot be formed with the correct amount of feed due to the influence of vibration of the feed wrapping device, and consequently, there is a problem that the weight of the packaged bales is not uniform.

[0007] Therefore, there is a need to improve this.

[0008] A related background technology is Korean Registered Patent Publication No. 10-2263267 (Registered June 4, 2021, Title: Feed Wrapping Device). The problem to be solved

[0010] The present invention was created in response to the aforementioned necessity, and aims to provide a precision weighing device for a fermented feed wrapping and packaging machine that can discharge a precise amount of fermented feed to the outside by having a load cell accurately measure the weight of the fermented feed without interference from vibrations occurring during the packaging process when the fermented feed is introduced into the weighing guide section. means of solving the problem

[0012] To achieve the above-mentioned objective, a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention comprises a fixed frame, a support frame disposed on the upper side of the fixed frame, a weighing guide provided on the support frame and storing fermented feed so as to be discharged so as to enable weighing of fermented feed introduced from the outside, and a load cell provided between the fixed frame and the support frame to measure the weight of the fermented feed stored in the weighing guide.

[0013] The above-described weighing guide is characterized by comprising a hopper member connected to a support frame so as to be received in the fixed frame, a dispersion discharge part provided on the hopper member and capable of discharging the fermented feed in a dispersed manner when the fermented feed is fed into the open upper side of the hopper member, and an opening / closing cover part provided on the hopper member and capable of covering the open lower side of the hopper member so as to be openable / closable.

[0014] The above dispersion discharge unit is characterized by comprising: a rotating shaft member rotatably provided in a pair spaced apart on the inner side of the hopper member; a driving providing member provided on the circumferential surface of the rotating shaft member to provide driving force to the rotating shaft member so that the rotating shaft member rotates collectively; a plurality of dispersion striking members formed protruding spaced apart along the circumferential direction of the rotating shaft member in the middle of the axial direction of the rotating shaft member to strike the fermented feed fed into the hopper member in a dispersion manner; and dispersion screws each extended on both sides of the axial direction of the rotating shaft member based on the dispersion striking members to disperse and discharge the fermented feed fed into the hopper member in the axial direction of the rotating shaft member.

[0015] The above-described opening / closing cover portion is characterized by including a cover member that is hinge-connected to a pair of hopper members to cover the lower side of the hopper member so as to be openable and closable, and an opening / closing guide cylinder that is hinge-connected to the periphery of the hopper member to rotate the cover member.

[0016] The fixed frame is fixed so as to be stackable in a wrapping machine that compresses fermented feed and packages it by wrapping, and the load cell is characterized by first weighing the weight of the fermented feed fed into the hopper member up to a lower limit value, and then secondarily weighing from the lower limit value to a set weighing value at the point when vibration caused by the operation of the wrapping machine is prevented from being transmitted to the fixed frame.

Therefore, the definitions of these terms should be based on the content throughout this specification.

[0025] FIG. 1 is a perspective view illustrating a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention, FIG. 2 is a front view illustrating a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention, FIG. 3 is a side view illustrating a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention, FIG. 4 is a plan view illustrating a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention, FIG. 5 is an operation diagram illustrating the operation state of the opening / closing cover part in a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention, FIG. 6 is a usage state diagram illustrating the usage state of a precision weighing device for a fermented feed wrapping packaging machine according to one embodiment of the present invention, and FIG. 7 is a usage state diagram illustrating the usage state of a precision weighing device for a fermented feed wrapping packaging machine according to another embodiment of the present invention.

[0027] As illustrated in FIGS. 1 to 7, the precision weighing device for a fermented feed wrapping packaging machine according to the present invention includes a fixed frame (100), a support frame (200), a weighing guide (300), and a load cell (400).

[0028] The fixed frame (100) provides a space for the support frame (200) and the load cell (400) to be installed.

[0029] The fixed frame (100) may include a plurality of vertical bars (110) spaced apart along a set trajectory and connecting bars (120) that interconnect the vertical bars (110). At this time, the fixed frame (100) may accommodate a wrapping machine so as to prevent the transmission of vibrations from the wrapping machine.

[0030] And, the support frame (200) is spaced apart from the upper side of the fixed frame (100). This support frame (200) is formed in the shape of a square frame and provides a space where the metering guide (300) is installed.

[0031] In addition, the weighing guide (300) is provided on the support frame (200) and stores the fermented feed so that it can be discharged, enabling weighing of the fermented feed introduced from the outside.

[0032] To this end, the weighing guide (300) includes a hopper member (310) that is supportedly connected to a support frame (200) so as to be received in a fixed frame (100), a dispersion discharge part (320) provided on the hopper member (310) and capable of discharging the fermented feed when the fermented feed is fed into the upper side of the hopper member (310), and an opening / closing cover part (330) provided on the hopper member (310) and capable of covering the lower side of the hopper member (310) so as to be openable / closed.

[0033] At this time, the hopper member (310) is formed with both the upper and lower sides open so that fermented feed is fed from the outside and the load cell (400) discharges the fermented feed to the outside when the weight of the fermented feed is measured.

[0034] Additionally, the dispersion discharge unit (320) comprises a rotating shaft portion (321) that is rotatably provided in a pair spaced apart on the inner side of the hopper member (310), a driving portion (322) that is positioned on the circumferential surface of the hopper member (310) and provides driving force to the rotating shaft portion (321) so that the rotating shaft portion (321) rotates collectively, a plurality of dispersion striking members (323) that are formed protruding spaced apart along the circumferential direction of the rotating shaft portion (321) in the middle of the axial direction of the rotating shaft portion (321) to strike the fermented feed fed into the hopper member (310) so as to disperse it, and a dispersion screw (324) that is formed extending on each side of the axial direction of the rotating shaft portion (321) based on the dispersion striking members (323) to disperse and discharge the fermented feed fed into the hopper member (310) in the axial direction of the rotating shaft portion (321).

[0035] At this time, the drive providing part (322) includes a drive motor (322a) that generates a driving force and a plurality of gear parts (322b) that collectively rotate the rotating shaft part (321) using the driving force of the drive motor (322a). Here, the drive motor (322a) may be an electric geared motor or a hydraulic motor capable of driving the rotating shaft part (321).

[0036] That is, when fermented feed is fed into the hopper member (310) while the rotating shaft member (321) is rotating collectively by the driving force of the driving member (322), the dispersion striking member (323) rotates together along the rotational direction of the rotating shaft member (321) to strike and disperse the fermented feed fed into the interior of the hopper member (310), and the dispersion screw (324) can crush the fermented feed fed into the interior of the hopper member (310) and simultaneously force the fermented feed to be discharged so that the fermented feed is dispersed in the axial direction of the rotating shaft member (321).

[0037] Additionally, the opening / closing cover portion (330) includes a cover member (331) that is hinge-connected to a pair of hopper members (310) to cover the lower side of the hopper member (310) so as to be openable and closable, and an opening / closing guide cylinder (332) that is hinge-connected to the periphery of the hopper member (310) to rotate the cover member (331).

[0038] That is, when the hopper member (310) is filled with a set amount of fermented feed, the cover member (331) is rotated by the operation of the opening / closing guide cylinder (332) to open the lower side of the hopper member (310), thereby supplying a fixed amount of fermented feed to the wrapping packaging machine.

[0039] Meanwhile, a plurality of load cells (400) are provided between the fixed frame (100) and the support frame (200) to measure the weight of the fermented feed stored in the weighing guide (300).

[0040] These load cells (400) are arranged to be connected to the upper part of the fixed frame (100) and the lower corner portion of the support frame (200), respectively.

[0041] That is, the load cell (400) measures the load of the support frame (200) applied to the fixed frame (100) when the fermented feed is filled into the hopper member (310) and measures the weight of the fermented feed.

[0042] At this time, when the measured value of the load cell (400) reaches a set value, the opening / closing guide cylinder (332) operates to contract so that the cover member (331) opens the lower side of the hopper member (310), and when the measured value of the load cell (400) is less than the set value, the opening / closing guide cylinder (332) operates to extend so that the cover member (331) covers the lower side of the hopper member (310).

[0043] Thus, in the precision weighing device for a fermented feed wrapping packager according to the present invention, when weighing fermented feed introduced from the outside while the wrapping packager is housed in a fixed frame (100), vibration effects caused by the operation of the wrapping packager do not affect the weighing of the fermented feed, so the weighing operation of the fermented feed and the wrapping operation of the wrapping packager can be performed simultaneously, thereby reducing working time and improving productivity.

[0044] Meanwhile, as shown in FIG. 7, the fixed frame (100) can be installed so as to be stackable in a wrapping machine that compresses and packages fermented feed.

[0045] At this time, the load cell (400) can first weigh the weight of the fermented feed fed into the hopper member (310) up to a lower limit value, and then, at a time when vibration caused by the operation of the wrapping packaging machine is not transmitted to the fixed frame (100), it can secondarily weigh from the lower limit value to a set weighing value.

[0046] For example, the set weighing value (450 kg) is measured by supplying external fermented feed to the hopper member (310) up to the lower limit value (400 kg), and then supplying external fermented feed to the hopper member (310) until the set weighing value (450 kg) is reached at a time when the vibration of the wrapping packaging machine is temporarily not transmitted to the fixed frame (100).

[0047] Thus, the load cell (400) can perform accurate weighing while preventing interference from vibrations caused by the operation of the wrapping machine when weighing the fermented feed filled in the hopper member (310), thereby improving the weighing precision.

[0049] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0050] Therefore, the true technical scope of protection of the present invention should be determined by the patent claims. Explanation of the symbols
