Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for separating meat attached to bones from bones.

The press piston is introduced from below into the press chamber of the nSl axis, and the upper end of the press chamber can be closed by a stopper during pressing, and the meat mass that has been turned into a paste is passed through the press chamber v>A/l&j niblets. However, it has an opening that does not allow bone to pass through.

The stopper can be moved between a position that closes the press chamber and a position that opens the press chamber; in the latter position the stop is a device on the side of a horizontal plate that connects to the upper end of the press chamber.

Although such a device is known (Auth IJA Patent No. 371,314), it has been shown in practice to be of value to companies processing large bones with attached flesh that place an emphasis on automation. There is. With this known device, therefore, the costs associated with automation, which require precisely guiding the movement of the stopper between the closing position and the opening position of the press chamber within 1%, are not a problem.

For small and medium-sized enterprises, equipment costs must be kept as low as possible, and some of the work is done by hand, so the cost of automation becomes an issue.

However, even in companies like this, only bones with a single piece of meat attached are pressed and left behind! ] The task of obtaining meat cannot be abandoned.

An object of the present invention is to provide an apparatus that can easily and reliably process bones with meat attached to obtain remaining meat lumps, although the cost is lower than that of the apparatus C with the known configuration described at the beginning. The goal is to provide the following.

The present invention solves this problem because the plate is wide in terms of the cross-sectional area of the press chamber (and can be freely approached from above).

A ms+v surface is formed for bones with meat attached, and the bones on this plate can be pushed into the press chamber by hand.

The solution is provided by a device characterized in that the stopper can be pivoted between a position for closing the press chamber and a position for opening the press chamber. [1] In the configuration of the present invention, the bone to be pressed with one hand is placed on the loading surface formed by the plate, and the stopper is located at a position where the press chamber is released. After turning to.

He was forced into the press room by hand. After the stopper is turned to a position that closes the press chamber and the press time and pressure are adjusted, the press operation is performed. After releasing the press pressure, the stopper is pivoted again to the position where it opens the press chamber. By means of the press piston, the pressed bone mass is forced out of the press chamber and removed manually from the loading surface.

This cycle is repeated after the press piston returns to its original starting position. These steps are carried out quickly and without any hesitation.
Moreover, it can be done without any training.

The operating speed of this device is substantially comparable to the automated loading f mentioned at the beginning. The swivel stop according to the invention costs substantially less than a stop moving along the guide of a straight riser, since it can be produced cheaper for the same 1.1 degree. Due to the large area of the loading surface formed by the plates, it is also easy to bring bones with meat into the device.

According to an advantageous embodiment of the invention - the stop can be pivoted about a vertical axis along the plate.

This is an advantage over stops that pivot about a horizontal axis. What happened - Horizontal axis rotation is basically possible, but the stopper suddenly rotates due to the influence of the press pressure caused by shutting off in the press-based closed position, resulting in a loss!
- This incurs additional costs.

Within the scope of the invention, it is advantageous for the stop to be located at a position which opens the pressing chamber on the six edges of the plate, avoiding the place where the pressed residual mass is discarded. In this way, the stopper does not prevent the removal of the remaining lumps.

The stopper touches the edge of the grate and edges the plate S7. 13. Make a series of 1"b. Conveniently, this enclosure forms a shallow dish with the plate. This is effective when the stopper is at the other end without closing the press chamber. A shallow dish, a loading surface formed as an enclosure that does not rise too high 1) prevents the pressing bones from accidentally scraping 1) from the loading surface.

In another configuration of the invention, the stopper is 1f from the plate.
fIZ can be rotated around the cylinders of the frame of this device, and which cylinders can be rotated together with other cylinders of the frame.

The horizontal main girder that supports the stopper is supported at P when the press room is closed. (As the bending force is absorbed by the lateral main girder, the turning part of one stopper is released from the bending force, and a large press pressure can be obtained without stress being applied to the turning part.

Within the scope of the invention, it is advantageous if the plate is rectangular and has an opening for the press chamber on the short side.

In particular, on the short side of the plate there is provided a slider for removing the pressed bone. This reduces the labor of the operator.

In order to prevent a work error in which the press piston moves before the stopper reaches its final position, the present invention provides terminal switches at both ends of the stopper rotation range to stop or cancel the piston movement. In order to facilitate manual rotation of the stopper, it is provided with a handle according to the invention.

Next, embodiments of the present invention will be described with reference to the drawings.

This device has a frame l, to which a hydraulic cylinder 2 is vertically fixed. The piston of the cylinder 2 is a press piston 3 that suppresses the bone 5 to which meat is attached. This press piston 3 is vertically introduced into the press chamber 4 from below. In the circular cross-section wall 6 of the press chamber 4 there are a number of small holes 7, which are shown here only by horizontal lines. These small holes 1 allow the flesh of the pressed mass, which has been transformed into a paste by the pressure of the press piston 3 in the press chamber 4, to pass through, but leave the pure bone behind. The pasty meat passes through the small hole 7 and enters the annular ring 8 between the outer wall of the wall 6 and the tube 9 surrounding the wall 6 - there it is collected and transferred to a connecting tube 10 (no. From Figure 3).

It is led out to the hose 11 connected to this.

During pressing, the stop 12 provides the necessary cradle for the pressed mass. This stopper 12 consists of a hollow cylinder and is closed at the bottom by a solid bottom wall 14. The stopper 12 is disposed on a first wide-surface plate 16 whose upper portion serves as a platform for manually pushing the bone 5 with meat attached into the press chamber 4, and is located coaxially with the press chamber 4. It can rotate around the vertical axis 17 between the press chamber 4 and a remote position. The first digit is shown in solid lines in FIGS. 1 and 2, and the first order position is shown in dotted lines.

This second position f4 is the position in which the terminal switch 18,19 is activated. The stopper 12 is connected to a vertical cylinder 21 (second.
It is fixed to two arms 20 that can rotate the rotation 1) in Fig. 3). A handle 22 is attached to the outside of one hollow cylinder 13 to facilitate turning. Cylinder 21
Together with the other cylinder 23 of the frame (1), it serves as a support for one horizontal main girder 24, and this horizontal main girder forms a smooth surface 25 with a flat lower surface on which the flat upper end 26 of the stopper 12 can slide.

Since the stopper 12 is supported by the horizontal main beam 24 at the upper part of the press chamber 4, the horizontal main beam 24 is supported by the press piston 3.
subject to press pressure. Therefore, the turning portion 2L21 of the stopper 12 is released from bending stress.

The plate 16 has a loading surface that is wider than the cross section of one press chamber 4 in order to place the pressed bone thereon. This loading surface can be freely reached from above, so that it can be placed on the plate 16 by hand from above 27.

The opening 28 of the pressing chamber 4 is provided on the narrow side of the plate, on which side there is a slide 29 for ejecting the remaining pressed bone. An upright enclosure 30 is provided on both the narrow and wide sides of the plate on the opposite side, forming, together with the plate 16, a flat plate bordered by an enclosure 80. The long side of the plate 16 is the enclosure 3 that is in contact with the cylinder 23.
0] - the other long side ends in an end position which opens the press chamber 4 some distance in front of the stopper 12. In these terminal positions the stops 12 - form an extension of the enclosure 80 and prevent the pressed bone from being forced out of the plate 16 unexpectedly.

Since the stopper 12 cannot be moved vertically, the wall 6 of the press chamber must be moved upwards while the press pressure is applied for one filling. For this purpose, the wall 6, together with the tube 9 surrounding it, is connected to a ring 31 which can be moved vertically into a circular opening 32 of one plate 16. Component 6.
9 are connected to each other at the bottom with an annular grate 33 on a raising member 34, which is further fixed to a piston rod 35 of a hydraulic cylinder 36 fixed to the frame 1. By means of this hydraulic cylinder 36 - the wall 6 which lifts the press piston 36 - one component 9-313
3-34 by a distance h (FIG. 3) - so that the outlet 28 of the press chamber 4 between this wall 6 and the stop 12 can be closed. The bottom wall 14 of the narrow cylinder 13 forms a one-step reduced portion 37 so that when the one wall 6 is lifted, it can be properly inserted into the press Y4.

This reduction part 37 is provided in order to ensure complete sealing.

O-ring 38 is inserted.

The functions of this device are as follows. The meat-bone mass to be pressed is carried by hand onto the plate 16 at 27 locations. On this plate, the stopper 12 is swiveled to the final position shown in broken lines, and one press chamber 4 is released. The bone to be pressed is manually dropped into the pressing chamber 4 through one opening 28. During this time, the stopper 12 is controlled by a terminal switch 18 integrated in the electrical control circuit of the device so that the press piston 3 cannot rise until the press chamber 4 is filled. In this case - the press piston 3 is in its rest position and the wall 6 recesses exactly into the plate 16, so that the pressing of the mass to be pressed into the press chamber 4 is not hindered. This pushing operation is also alleviated by the loading surface formed by the otherwise wide plate 16. In this case, when the enclosure 30 and the stopper 12 are turned away from the press chamber 4, fi? Guide the joint in the direction r31028 of the press chamber 4 at i:. After the press chamber 4 is completely filled.

The stopper 12 is pivoted by hand to the position shown in real life.

This position is above the press chamber 4 - this essentially closes the press chamber 4. This final position is arm 2
0 and is monitored by the terminal switch 19. In contrast, the terminal switch 18 is actuated by the outer wall of the hollow cylinder 3. The terminal switch 19 deactivates the press cylinder 2 and the other cylinders 36, and by the automatic control of one device, the cylinder 36 is first
Since the press chamber 4 acts to be lifted upward by a certain amount, the upper part of the press chamber 4 is closed. The cylinder 2 is then activated to press the fleshy bone into the press chamber 4. Due to the pressing pressure, the pulp of the pressed material in paste form leaves the pressing chamber 4 or the annular chamber 8 through the hose 11 and is collected in a container, not shown.

Pressing time and pressure can be effectively adjusted. After the end of the press, the pressure in the cylinder 2-36 is released, on the one hand the press chamber 4 becomes depressurized, and on the other hand the wall 6 is lowered again.

After the downward movement of the wall 6 has ended, the stop 12 is swiveled out of the hand again into its end position, shown in broken lines, and abuts the terminal switch 18. As a result, the movement of the cylinder 2 which had been interrupted by the terminal switch 19 resumes, and the impulse aimed at starting the press piston 3 by means of the electrical stop 111 of the device is released. And Presvington 3 is-
As soon as the pressed residual mass of 1"J" is lifted into the press chamber 4 and pushed upwards from the press chamber 4, the pressed residual mass is manually pushed from the plate 6 to the slide - from the slide to the figure. It is poured into a container, not shown.After the piston 3 has returned to its lower rest position - the cycle is repeated.

As is clear from the figure, the one-end switches 18 and 19 prevent the movement of the mass to be pressed on the loading surface 16 and the pushing of the remaining mass of pressed bone onto the slide 29.VCIII
[There are 18 locations. For the latter reason, the end-of-life switch 19
Advantageously, it acts on the arm 2o and not on the outer wall of the hollow cylinder 13 forming the stop 12.
