Description

Fork device with flow prevention function}

The present invention relates to a fork device equipped with a flow prevention function. More specifically, the present invention relates to a fork device equipped with a flow prevention function. More specifically, when meat is picked up and fixed with a fork member or when the fork member is moved upward to fix meat, the operating lever may not cross an arbitrary center line. It relates to a fork device equipped with a flow prevention function that ensures safety by locking the fork member when the fork member is locked.

Generally, when meat is handled in stores, it is processed (cut) into appropriate sizes and distributed or stored. Such meat processing was carried out manually by workers using cutting knives.

Therefore, the size of the meat pieces being processed (cut) varied depending on the personal opinions and tastes of the workers, resulting in a lack of uniformity in the product. Additionally, in the case of poultry meat containing bones (pheasant, duck, chicken, etc.), there was a problem in that it was difficult for workers to perform the work manually.

As shown in FIG. 1, a conventional meat cutting device includes a work table 110 with a groove 160 on which meat is placed and a saw blade is moved, and is rotated by a drive motor and moved perpendicularly to the surface of the work table 110. A band saw 120 that cuts meat, a positioning device 130 that determines the position of the meat, and a protective cover 14 that protects the operator and the band saw 120 when the band saw 120 rotates. , It consists of a stand 150 that supports the above-described devices.

In the meat cutting method of the conventional meat cutting device configured as described above, the band saw 120 is rotated and moved in the vertical direction with respect to the surface of the work table 110 according to the driving of the drive motor, and the band saw 120 and the positioning device 130 ) By adjusting the spacing, the cutting thickness of the meat to be cut is adjusted. The meat is placed on the work table 110, placed in close contact with the positioning device 130, and the rotational force of the drive motor is transmitted to rotate the band saw 120. Cut the meat by pushing and moving in the direction.

Since the above-described conventional meat cutting device grabs and pushes low-cost meat and cuts it into small pieces, the applicant has a safety accident risk problem, and in order to solve the conventional problem, the applicant uses a meat cutting device as described in Korea Utility Model Registration No. 0477132 (see FIG. 2). A work table 100 on which a work table 100 is placed and which is formed with a groove through which the saw blade moves, a band saw 200 that is rotated by a drive motor and moves perpendicularly to the surface of the work table 100 to cut meat, and a position that determines the position of the meat. It consists of a crystal device 300, a protective cover 400 that protects the operator and the band saw 200 when the band saw 200 rotates, and a stand 500 that supports the devices.

Meanwhile, the worktable 100 has a structure in which a table 700 on which meat to be cut is placed and a guide member 600 that moves the table 700 in the front and rear direction of the worktable 100 is installed.

As shown in FIG. 3, the cutting method of the conventional meat cutting device configured as above is to pull and move the table 700 toward the operator before cutting, place the meat on the table 700, and then move the table 700 to the table 700. When the band saw 200 is pushed to a position, the table 700 is moved by being guided by the guide member 600.

When the table 700 is moved, the meat to be cut is pressed by the positioning device 300 using the moving pressing member 710, and then the table 700 is pushed, and the meat is cut by the band saw 200. It is cut.

In the conventional meat cutting device configured as above, the meat must be held by hand and pushed toward the band saw 120 while the band saw 120 is rotating. Therefore, if the operator makes a mistake, his or her fingers, etc., will be hit by the saw blade of the band saw 120. There is a problem that damage occurs due to cutting.

In addition, in order to avoid this problem, there are many parts where the worker holds the meat, so a large amount of meat is not cut when cutting, so the part of the meat held by the worker must be cut by the worker directly using a separate cutting tool, such as a knife. There was a hassle.

In consideration of the above-mentioned problems, the present applicant proposes that the method of fixing the meat to be cut is to rotate the meat using tongs rotating means having a fork shape, as shown in Korean Patent Registration No. 1908106. It was simply fixed.

This conventional meat cutting device simply rotates the fork member to fix the meat, so that when the fork member is touched when cutting the meat or fixing the meat, the fork member easily rotates and moves, causing the problem of the meat being separated during cutting. There is also a major problem of safety accidents occurring due to movement of the fork member.

Republic of Korea Patent Registration No. 1908106 Republic of Korea Utility Model Registration No. 0477132

The purpose of the present invention, which was devised in consideration of the above-described conventional problems, is to

First, it prevents safety accidents by allowing you to safely cut meat without holding it with your hands while the band saw is rotating.

Second, since there is no part for the worker to hold the meat being cut, it eliminates the hassle of the worker cutting it separately using a knife, etc., and then manufacturing it.

Third, to prevent the fork member from being easily moved by an external force or the fixing force holding the meat to be released, and furthermore, to prevent the fork member from easily moving when fixing the meat, the safety operating lever must not cross any center line. The object is to provide a fork device with a flow prevention function that has the advantage of preventing the fork member from being easily released by providing a safety device that locks the fork member when the fork member is locked.

The object of the present invention described above is a fork device for fixing cut meat, comprising: a fork member for fixing the meat; A moving plate on which the fork member is fixed and installed by bolts; Slide guide members installed at both ends of the moving plate and moving on the main frame; An L-shaped operating connection member on the opposite side of the position where the fork member is installed centered on the moving plate; an operating lever that raises and lowers the fork member; a rod member that reciprocates up and down by the operating lever; an operating plate fixed to an end of the rod member; a connecting member installed between the operating member and the rod member; The connecting member is installed on a fixed bracket fixed to the main frame and includes a spring installed while connecting the operation plate and the moving plate; This is achieved by a fork device with a flow prevention function, wherein the operating plate and the L-shaped operating connection member are partially installed overlapping each other.

This is achieved by a fork device with a flow prevention function, wherein a soft and elastic shock absorbing member is further installed in the guide hole of the fixing bracket.

This is achieved by a fork device equipped with a flow prevention function, wherein the fork member is fixedly installed with bolts and can be separated and coupled.

According to the present invention, when meat is picked up and fixed with a fork member or when the fork member is moved upward to fix meat, when the operating lever crosses an arbitrary center line, the fork member is moved by an external force. It has the effect of preventing the fork member from moving easily when the meat is being fixed, thereby preventing safety accidents.

Hereinafter, a preferred embodiment of the present invention will be described in detail based on the attached drawings.

The attached drawing, Figure 4, is an exploded perspective view showing the structure of a fork device equipped with a flow prevention function to which the technology of the present invention is applied, and Figure 5a is a front perspective view showing the structure of a fork device equipped with a flow prevention function to which the technology of the present invention is applied. Figure 5b is a rear perspective view showing the structure of a fork device equipped with a flow prevention function to which the technology of the present invention is applied, and Figure 6 is a structure of a fork device equipped with a flow prevention function according to the present invention and its operating state when meat is fixed. As a cross-sectional view showing, the fork device (1) equipped with a flow prevention function according to the present invention has a slide guide member ( 20) is installed, and an L-shaped operating connection member 15 is bolted to the opposite side of the position where the fork member 12 is installed.

The slide guide member 20 is preferably made of a strong synthetic resin material or rubber material. The reason is that since the main frame (not shown) is made of metal, it prevents the generation of noise due to friction and can also have a shock absorption effect due to shaking.

The structure of the slide guide member 20 is provided with a guide groove 21, so that it moves according to the operation of the movable plate 10 and prevents the movable plate 10 from shaking and easily guides the up and down movement.

An operating lever 11 for raising and lowering the fork member 12 is rotatably installed on a connecting member 17 installed on a fixing bracket 16 fixed to a main frame (not shown), and the connecting member 17 Basically, it is made of one piece and is installed in connection with a rod member 18 that reciprocates up and down, and the rod member 18 is installed to penetrate the guide hole 16a formed in the fixing bracket 16.

Meanwhile, as shown in Figure 9, a shock absorbing member 30 made of an elastic material is installed in the guide hole 16a to absorb the shock and vibration of the rod member 18 that reciprocates up and down, and the rod member ( 18) is formed in a rod shape with a circular cross section.

In the present invention, the structure is explained in that the operating lever 11 is connected to the connecting member 17 and rotates, but a cylinder can also be used, and it moves up and down and stops when a certain torque is applied when fixing the meat. It can be used by replacing it with a structure that can be used by changing it to .

Meanwhile, an operating plate 19 is installed at the end of the rod member 18, and both ends of the operating plate 19 are connected by springs 19a, and the operating plate 19 and the L-shaped operating connection member are connected. (15) is a structure in which parts are installed overlapping.

The operating states of the fork device (1) with a flow prevention function of the present invention having the structure described above include three operations: an operation to fix meat, an operation to unfix meat, and a direction change operation to clean and release meat. It can be explained by dividing it into operations.

First, the operation of fixing the meat is performed by rotating the operating lever 11 rotatably installed on the fixing bracket 16 to the right as shown in FIG. 6 and pressing the rod member 18 combined with the connecting member 17. ) moves downward, and at the same time, the operating plate 19 installed at the end of the rod member 18 also moves downward.

When the operating plate 19 moves downward, the moving plate 10 is pulled downward because the spring 40 is connected to the operating plate 19. As the movable plate 10 moves, the fork member 12 and the L-shaped operating connection member 15 fixed to the movable plate 10 move downward at the same time. Therefore, the meat moving to the lower part is fixed by the fork member (12). In addition, meat is prevented from being pushed by being in close contact with the moving plate 10.

On the other hand, when the size of the meat to be cut is small, the rod member 18 is moved downward, as shown in Figure 5a of the attached drawing, and the operating plate 19 installed at the end of the rod member 18 is also moved downward. Since the moving plate 10 moves by the spring 40 connected to the operating plate 19, it is fixed by the fork member 12.

However, when the size of the meat is large, the rod member 18 moves downward and the operating plate 19 installed at the end of the rod member 18 also moves downward, and the spring 40 connected to the operating plate 19 ) Because the movable plate 10 moves, it is primarily fixed by the fork member 12, and as the moving distance of the rod member 18 becomes shorter, the moving distance of the fork member 12 naturally becomes shorter and comes into contact with the meat. I do it.

When the size of the meat is large, the fork member 12 fixes the meat by the elastic force of the primary spring 40, but the operating lever 11 rotates further even when fixed by the primary fork member 12. When the operating plate 19 and the L-shaped operating connection member 15 partially overlap, the operating plate 19 presses the L-shaped operating connecting member 15, thereby increasing the fixing force.

On the other hand, as shown in Figure 6 of the attached drawing, when the operating lever 11 is rotated counterclockwise by a certain angle to release the fork member 12 from holding the meat, or the operator fully operates the operating lever 11. When you need to rotate but forget to do this for a moment

Since the operating lever 11 rotates counterclockwise, the rod member 18 moves upward a certain distance according to the principle of link operation, thereby releasing the fixing force. However, even if the rod member 18 moves a certain distance, the fork member 12 maintains the state of fixing the meat until this time.

That is, even if the rod member 18 is moved upward, the spring 40 is compressed and if the moving plate 10 cannot be moved upward due to the compressive force, the fork member 12 maintains the state of fixing the meat. do.

As shown in Figure 6, when the operating lever 11 is stopped while partially rotating counterclockwise, the fork member 12 or the rod member 18 maintains its current state. In other words, it means that the operating lever 11 is maintained in the rotated state as shown in Figure 6 of the attached drawing.

It does not rotate or move downward due to the self-weight of the operating lever 11 and the rod member 18 and maintains its current state. The method of maintaining the current state is when the position of the hinge axis where the operating lever 11 and the connecting member 17 are hinged is moved to one side of the center line rather than any vertical center line.

Because the center of gravity changes position due to the angle between the vertical center line and the center line of the hinge axis, and movement is restricted, the operating plate 19 or the moving plate 10, rather than the operating lever 11, is pressed by external force. It will remain in safe mode, where it will not be moved.

Meanwhile, as shown in Figure 9 of the attached drawing, the rod member 18 penetrating the shock absorber 30 made of rubber or synthetic resin can be maintained in a stationary state by a certain frictional resistance, and the force exceeding the certain resistance is When transmitted, the rod member 18 moves the shock absorber 30 up and down. The main factors of the safe mode state are realized by friction force and center line misalignment.

Meanwhile, the operation of lifting the fork member 12, which was expressing the fixing force by cutting the meat, to the top is performed by rotating the operating lever 11 counterclockwise, as shown in Figure 8 of the attached drawing, and operating the operating lever 11 located on the right. ) is moved to the left, the rod member 18 is pulled upward and moved by the rotational force of the operating lever 11, and at the same time, the operating plate 19 moves upward and pressurizes the spring 40, thereby compressing it. When the spring 40 lifts and moves the movable plate 10 upward, the fork member 12 that was fixing the meat breaks away from the meat, thereby terminating the fixing force.

According to the present invention, when meat is picked up and fixed with a fork member or when the fork member is moved upward to fix meat, when the operating lever crosses an arbitrary center line, the fork member is moved by an external force. It has the effect of preventing the fork member from moving easily when the meat is being fixed, thereby preventing safety accidents.
