Description

[Technical Field]

[0001] The present invention relates to a safety device for a meat cutting machine, which is fixed to a work table that can be moved horizontally and vertically using a fork means, and then allows the operator to easily and conveniently cut meat to a specified size while moving the work table, and also protects the operator's body when cutting meat. [Background technology]

[0002] Generally, when meat is sold in stores, it is processed (cut) into suitable sizes for distribution or storage. This meat processing is done manually by workers using cutting blades.

[0003] Therefore, the size of the meat pieces to be processed (cut) varies widely depending on the individual opinions and preferences of the workers, making it difficult to achieve uniformity in the products. Also, when using domestic meats containing bones (pheasant, duck, chicken, etc.), it is difficult for workers to work manually.

[0004] As shown in FIG. 1, a conventional meat cutting device is composed of a work table 110 on which meat is placed and which has a groove 160 formed therein along which the saw blade moves, a band saw 120 which is rotated by a drive motor and moves perpendicularly to the surface of the work table 110 to cut the meat, a positioning device 130 which determines the position of the meat, a protective cover 140 which protects the operator and the band saw 120 when the band saw 120 rotates, and a support stand 150 which supports the above devices.

[0005] In the conventional meat cutting device configured as above, the band saw 120 is driven by the drive motor to move vertically on the surface of the work table 110 to cut meat.

[0006] The meat is placed on the surface of the work table 110, and the position and thickness of the meat to be cut are determined using the meat positioning device 130. For example, the thickness of the meat to be cut is determined by the gap between the positioning device 130 and the band saw 120.

[0007] When an operator applies power to the drive motor, the band saw 120 moves vertically relative to the work table 110. At this time, the operator places meat in close contact with the positioning device 130 and pushes it toward the band saw 120, causing the meat to be cut by the band saw 120. After that, the operator uses the positioning device 130 to reposition the meat, and continues cutting the meat by pushing the meat.

[0008] In the conventional meat cutting device configured as described above, the operator must directly pick up meat with his / her hand and push it towards the band saw 120 while the band saw 120 is rotating, which poses a problem in that if the operator is not careful, his / her fingers or other parts of his / her body may be cut by the saw blade of the band saw 120.

[0009] Furthermore, if the worker cuts more meat to avoid such problems, a large amount of meat will not be cut during cutting, and the worker will have to cut the meat using a separate cutting tool, such as a knife, which is a hassle. [Prior art documents] [Patent documents]

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] As shown in FIG. 1 of the accompanying drawings, the installation structure of the stabilizing device for a meat cutting device of the present invention is installed on the work table 110 of the meat cutting device and fixes the meat with the fork means, which has the advantage of providing stability and preventing safety accidents for the operator. In addition, the safety device 1 with the meat fixed thereon can be moved in the X and Y directions on the work table 110 to cut the meat into a certain size, which is a convenient and safe device.

[0023] 2 and 3 of the accompanying drawings, the structure of the safety device 1 for a meat cutting machine of the present invention is comprised of: a fixing means 10 that moves the fork members 12 up and down with an operating lever 11 to fix the meat so that it does not move; a safety moving frame 20 that has moving rollers 23 that make it easy to move when the fixing means 10 is pushed and pulled by gripping a handle 25 provided on a main frame 21 on which the fixing means 10 is installed; a base table 30 that has guide parts 32 that guide the safety moving frame 20 and moves in the Y direction perpendicular to the X direction when the direction of movement of the safety moving frame 20 is left and right, i.e., the X direction; and a base table guide means 40 that has connecting plates 41 at both ends of a guide rod 42 inserted into the guide part 32 of the base table 30 and that are fixed to the work table 110 of the meat cutting machine with bolts, and that guides the movement of the base table 30.

[0024] As shown in Figures 4 and 5a of the accompanying drawings, the structure of the fixing means 10, which is the technical gist of the present invention, is such that sliding guide members 14 are installed on both ends of a movable plate member 13 to which fork members 12 for fixing meat are fixed by bolts, and an L-shaped operating connecting member 15 is fixed by bolts on the opposite side of the position where the fork members 12 are installed.

[0025] The sliding guide member 14 is preferably made of a strong synthetic resin or rubber, because this prevents noise caused by friction since the main frame 21 is made of metal, and also has the effect of absorbing shock caused by vibration.

[0026] The sliding guide member 14 has been described as having a groove made of synthetic resin that moves along the main frame 21, but the structure of the sliding guide member 14 may be modified so that it moves along the main frame 21 using a pair of moving rollers.

[0027] An operating lever 11 for raising and lowering the fork member 12 is rotatably mounted on a connecting member 17 mounted on a fixed bracket 16 fixedly mounted on a safety moving frame 20, and a rod member 18 that moves up and down is connected to the connecting member 17, and the rod member 18 is installed by passing through a guide hole 17a formed in the fixed bracket 16.

[0028] In the present invention, the operating lever 11 is connected to the connecting member 17 and rotates, and its structure has been described. However, a cylinder may be used, and the structure may be changed so that the lever stops when a certain torque is applied while the lever moves up and down to fix the meat.

[0029] Meanwhile, an actuating plate 19 is installed at the end of the rod member 18 and is connected to form a T-shaped cross section, and both ends of the actuating plate 19 are connected by springs 19a, and the actuating plate 19 and the L-shaped actuating connecting member 15 are installed so that they partially overlap.

[0030] As mentioned above, the structure in which the actuating plate 19 and the L-shaped actuating connecting member 15 are partially overlapped is intended to flexibly accommodate different sizes of meat. That is, although the present invention has been described assuming a minimum size of meat, as shown in Figure 5a of the accompanying drawings, when the piece of meat to be cut is large, the actuating plate 19 and the L-shaped actuating connecting member 15 are spread apart, and the fork members 12 hold the meat.

[0031] As shown in Figures 6 and 7a of the accompanying drawings, the structure of the safety moving frame 20 described above is a structure comprising: a main frame 21 on which fixing means 10 having fork members 12 is installed, which is fitted into the groove of the sliding guide member 14 to provide a guiding effect for the sliding guide member 14 to move up and down; a space frame 22 installed at the lower end of the main frame 21 to prevent overturning and maintain a constant distance; separation prevention plates 24 fixed to both ends of the space frame 22 to prevent separation of the moving rollers 23; and a moving roller 23 rotatably mounted between the main frame 21 and the separation prevention plates 24, which runs along the bent portion 33 of the table member 31.

[0032] The space frame 22 has the effect of preventing the main frame 21 from tipping over and stably holding the lower end of the main frame 21 when the safety moving frame 20 is moved by pushing or pulling it.

[0033] An unexplained reference numeral 25 denotes a handle. The handle 25 is used when moving the safety moving frame 20 in the X or Y direction. At this time, as shown in Figure 8 of the accompanying drawings, a second fork member 27 is further rotatably installed on the safety moving frame 20, which enables the meat to be firmly fixed, thereby minimizing the shaking of the meat when it is cut by the band saw 120.

[0034] When the meat is secured using only the fork member 12, there is an advantage that the meat can be cut to the maximum extent possible, but if the meat block itself is large, there is a risk of vibration occurring during cutting, so the second fork member 27 is used as an auxiliary.

[0035] When the meat has been cut up to the portion fixed by the second fork member 27, the second fork member 27 can be rotated on its hinge to separate from the band saw 120 so as not to collide with it, allowing the meat to be cut up to the portion fixed by the fork member 12. This prevents the operator from picking up the meat with their hands and cutting it, which has the advantage of preventing safety accidents. Meanwhile, the space frame 22 has a structure in which fixing pins 26 for fixing the meat are further formed on the upper surface of the end portion thereof.

[0036] As shown in Figures 9 and 10a of the accompanying drawings, the structure of the base table 30 is such that both ends of a table member 31 are bent upward to integrally form bent portions 33 through which the movable rollers 23 are guided, and the safety moving frame 20 is mounted between the bent portions 33 to prevent loose movement. A moving wheel 35 is installed on the bottom surface of one side of the table member 31, and a guide portion 32 into which a guide rod 42 is inserted is formed in the direction opposite to the moving wheel 35. At this time, stoppers 34 are formed on both ends of the bent portion 33 of the table member 31, so that the movable rollers 23 are engaged with the stoppers 34 to prevent the safety moving frame 20 from coming off.

[0037] The moving wheel 35 has a structure consisting of a cap and a spherical ball that partially passes through a through-hole of the cap. The moving wheel 35 has the advantage of being freely movable without any directionality. Of course, the structure of the moving wheel 35 is not limited as long as the base table 30 can be moved.

[0038] To secure and release the meat in accordance with the present invention having the above-described structure, as shown in Figure 7b of the accompanying drawings, the handle 25 of the safety moving frame 20 is taken to the dotted line position and moved away from the band saw 120 to ensure safety, and then the meat to be cut (edible meat) is secured downward using the securing pin 26 formed on the space frame 22, and then the operating lever 11 is taken downward and pressed to secure the meat, as shown in Figures 5a and 12b.

[0039] As described above, as shown in Figures 5a and 12b, when the operating lever 11 is pressed downward to fix the meat, one end of the operating lever 11 rotates downward while being hinged by the connecting member 17 installed on the fixing bracket 16, and presses the rod member 18 connected to the end downward.

[0040] At this time, the rod member 18 that has been pressed downward moves along the guide hole 17a formed in the fixed bracket 16 while being prevented from moving freely, and since the operating plate 19 is installed at the end of the rod member 18 that has moved downward as described above, the operating plate 19 connected in a T-shape also moves downward at the same time.

[0041] When the actuation plate 19 moves downward, the actuation connecting member 15, which is installed so as to overlap a part of the actuation plate 19, is pulled downward, and accordingly, the spring 19a connected to the actuation plate 19 is also pulled.

[0042] Therefore, when the spring 19a and the operating connecting member 15 move downward, the movable plate 13 connected to the connecting member 17 and the fork members 12 installed on the movable plate 13 also move downward in unison. At this time, the sliding guide members 14 installed on both ends of the movable plate 13 move along the main frame 21 to fix the meat.

[0043] As described above, after the meat is secured using the fork members 12, the handles 25 of the safety moving frame 20 are taken and the safety moving frame 20 is brought into close contact with the side of the meat positioning device 130.

[0044] When the safety moving frame 20 moves toward the meat positioning device 130, the meat (edible meat) fixed to the fork members 12 is tightly attached to the positioning device 130. At this time, the safety moving frame 20, as shown in FIG. 7b of the accompanying drawings, is structured to include a space frame 22, separation prevention plates 24 fixedly installed at both ends of the space frame 22 to prevent the separation of the moving rollers 23, and the moving rollers 23 rotatably installed between the main frame 21 and the separation prevention plates 24 and running along the bent portion 33 of the table member 31.

[0045] Meanwhile, fixing pins 26 for fixing meat are further formed on the upper surface of the end of the space frame 22, and the fixing pins 26 fix the meat at the bottom and are fixed at the top by the fork members 12, so that the meat is firmly fixed.

[0046] Once the meat is secured as described above, the operator takes the handle 25 provided on the main frame 21, first places the secured meat tightly against the positioning device 130 provided on the meat cutting machine, and then pushes it toward the band saw 120. The distance between the positioning device 130 and the band saw 120 becomes the thickness of the meat, and the meat is cut.

[0047] If the movement of the safety moving frame 20 to come into close contact with the positioning device 130 provided in the meat cutting machine is defined as movement in the X direction, the operator uses the handle 25 to push it to one side in the drawing to come into close contact with the positioning device 130. At this time, if the movement of the safety moving frame 20 is defined as movement in the X direction, it moves along the bending portions 33 provided on both ends of the table member.

[0048] 11 of the accompanying drawings, the moving rollers 23 rotatably mounted between the main frame 21 and the anti-detachment plate 24 move along the bent portion 33. At this time, stoppers 34 are formed on both ends of the bent portion 33 of the table member, and the moving rollers 23 are hooked onto the stoppers 34 to prevent the safety moving frame 20 from coming off.

[0049] Meanwhile, pushing the safety device of the present invention in the band saw direction to move it can be defined as movement in the Y direction. The movement in the Y direction is achieved by horizontal movement along a guide rod 42 that is installed at one end of a table member 31 constituting the base table 30 by a connecting plate 41 that is fixed to the work table of the meat cutting machine with bolts and that penetrates the guide portion 32.

[0050] When the table member 31 moves horizontally along the guide rod 42, the base table 30 can move easily since the moving wheel 35 is installed on the other bottom surface of the table member 31.

[0051] When replacing the cut meat with new meat or removing the remaining chunk of meat after cutting, the safety device is moved away from the installation location of the band saw, and then the operating lever 11 shown in Figure 5 of the accompanying drawings is rotated upward in the opposite direction, and the rod member 18 connected to the end thereof is moved upward.

[0052] At this time, the rod member 18 that has been pressed downward moves upward along the guide hole 17a formed in the fixed bracket 16 while being prevented from moving freely, and an operating plate 19 that is connected in a T-shape to the end of the rod member 18 that has moved upward as described above also moves upward at the same time.

[0053] When the actuating plate 19 moves upward, the actuating connecting member 15, which is installed so as to overlap with the actuating plate, is pulled upward and presses the spring 19a connected to the actuating plate 19.

[0054] Therefore, when the spring 19a and the operating connecting member 15 move upward, the movable plate 13 connected to the operating connecting member 15 and the fork members 12 attached to the movable plate 13 also move upward in unison. At this time, the sliding guide members 14 attached to both ends of the movable plate 13 move along the main frame 21, thereby releasing the force that has been holding the meat in place. [Industrial Applicability]

[0055] This invention is a useful invention that has the advantages of being able to move the fork means used to cut the meat in the direction of the band saw used as the cutting means, and using the fork means to hold the meat in place provides stability and prevents safety accidents for the worker, and also has the advantages of being able to move the work table on which the meat is placed in a direction perpendicular to the direction of movement of the fork means, allowing the meat to be cut into a set size simply and conveniently.
