Description

  The present invention relates to a frozen meat cutting apparatus for cutting block-shaped frozen meat into small pieces. Specifically, the frozen meat cutting and frozen parts are integrated into a unit, and this frozen meat cutting unit is supported on a gantry so that it can be moved between the cutting work position and the frozen meat charging position. Relates to the device.

  A conventional frozen meat cutting machine related to the present invention includes Patent Document 1 by the present applicant. The frozen meat cutting machine described in this publication is of the most standard form, and is a transfer formed on the upper surface of the machine base toward a rotating cylinder supported by one end of the machine base. The frozen meat placed on the table is pressed with a pressing plate and cut with a cutting blade provided on the peripheral surface of the cylindrical body.

Normally, in this type of frozen meat cutting machine, the meat piece cut by the cutting blade provided on the peripheral surface of the cylindrical body is directly received by a trolley wagon (moving container) or the like, and the outlet for the cut meat piece is fixed. Requires ground clearance.
Even in the frozen meat cutting machine described in Patent Document 1, the discharge port is configured to maintain a certain ground height, and therefore a frozen meat transfer table is formed on the upper surface of the machine base at a relatively high position. It took labor to lift the transfer table to the upper surface height position when putting frozen meat.

  In addition, since the machine base is formed by a box-shaped body whose periphery is covered with a wall plate, the impact sound generated when the frozen meat collides with the rotating cutting blade is amplified by the resonance phenomenon and noise is generated. Sometimes it grew.

  The frozen meat (thing) cutting device disclosed in Patent Document 2 has a configuration in which a cylindrical body (drum) having a cutting blade on the peripheral surface is provided at the front of an inclined transfer (supply) table.

  Design Literature 1 discloses a configuration in which a frozen meat cutting device and a rocking lift device that lifts frozen meat up to the frozen meat input (supply) port of the cutting device are incorporated in the same machine at the top of the chopper.

Also in the configuration of Patent Document 2, the transfer table is inclined, and a lifting labor is required for feeding frozen meat to the upper end of the transfer table.
Or, as disclosed in Design Literature 1, a lift device is required.

In addition, when the transfer table is steeply inclined as in Patent Document 2 and Design Document 1, when frozen meat is thrown in, frozen meat falls down to the cylinder body by its own weight. There are concerns about blade spills due to collision.
Furthermore, since the frozen meat is not fixed, the cutting thickness is not stable because the frozen meat moves backward when the cutting blade bites into the frozen meat. This tendency is prominent when the degree of pressing of the frozen meat against the cutting blade changes depending on the remaining amount of frozen meat.
In addition, the retraction of the frozen meat when it is cut leads to the freezing of the frozen meat on the transfer table and causes noise.

Further, in the inclined transfer table as described above, when the operation is stopped while the frozen meat placed on the table remains in the cutting state, the frozen meat being cut can be taken out of the machine. It was difficult.

Easy to input.

  In addition, when a work state in which the unit is inclined downward toward the cylinder body is selected, the frozen meat has a cutting blade provided on the circumferential surface of the cylinder body by a combined force of its own weight due to the inclination and the pressing force of the pressing plate by the air cylinder. Since the frozen meat does not move backward and move freely during cutting, stable cutting is possible and noise generation can be suppressed.

  Further, when the cutting operation is stopped and the frozen meat being cut out is taken out of the machine, the pressing plate is lowered when the unit is moved to the frozen meat charging position and the piston rod of the air cylinder is contracted. As the pressing plate is lowered, the frozen meat supported by the pressing plate slides down to the stop position of the pressing plate.

  According to the invention of claim 2, the gantry is composed of a frame having an open wall surface, and noise generated when cutting frozen meat is not amplified unlike a conventional box-type gantry.

Can be combined.

As described above, in the present invention, a set of functional parts for frozen meat cutting such as transporting, cutting, pressing, driving motor, and operation panel of frozen meat is combined into a unit so that combinations with various mounts are possible. Easy.
If the assembly-related parts of the gantry and unit are standardized, compatibility will occur and it will contribute to rationalization in terms of production, sales and distribution, and will also improve convenience.

  A frozen meat cutting apparatus embodying the present invention will be described with reference to the drawings. FIG. 1 is a side view of a first embodiment according to the present invention, and FIG. 2 is a front view of FIG. FIG. 3 is a side view of the second embodiment.

  First, the structure of the frozen meat cutting unit 1 will be described in detail with reference to FIGS. 1 and 2. At the tip (left side in FIG. 1) of a frozen meat cutting unit (hereinafter simply referred to as “unit”) 1, a cylindrical body 2 having a known peripheral surface with a frozen meat cutting blade (not shown) is cut. The chamber 3 is rotatably supported.

  In the cutting chamber 3, a frozen meat feed port (not shown) is provided on the inlet side, and a cut meat outlet 3 a is provided on the outlet side, as in a conventional cutting machine. It is opened over.

  A motor box 4 is connected to one side of the cutting chamber 3, and a motor 6 with an orthogonal speed reducer in which an output shaft is directly mounted on the shaft end of the cylindrical body 2 is housed in the motor box 4. Yes. The cylindrical body 2 can be rotated / stopped via the motor 6 by operating an operation tool such as an operation button provided on a driving operation panel described later.

  A control panel 22 composed of a PLC (programmable controller) that controls operation of the unit 1 is housed in the space of the rear extension (right side in FIG. 1) of the motor box 4 although detailed display is omitted.

  A transfer table 7 made of a plate material on which the frozen meat is placed is extended from the bottom of the frozen meat inlet of the cutting chamber 3 toward the rear (right side in FIG. 1). A cover 8 is attached to the transfer table 7, and the cover 8 is configured to be opened when frozen meat is put in or taken out as indicated by a virtual line in FIG. 2.

On the rear end side (right side in FIG. 1) of the transfer table 7, a flat plate-shaped rear supply table 9 having a slight difference from the transfer table 7 and having a slip-preventing plate 9a at the open end is provided. However, the width of the transfer table 7 is provided.
This machine has a configuration in which frozen meat can be placed on the rear supply table 9 and frozen meat can be fed onto the transfer table 7 also from the rear end of the transfer table 7.
In this case, when the unit 1 is tilted forward after placing the frozen meat on the rear supply table 9, the frozen meat slides on the transfer table 7 by its own weight.

  A pressing air cylinder 10 is horizontally mounted on the lower side of the rear supply table 9. At the tip of the piston rod of the cylinder 10, a pressing plate 11 that presses the frozen meat placed on the transfer table 7 of known technology toward the cylindrical body 2 is mounted.

As described above, a frozen meat cutting unit in which functional parts for cutting frozen meat such as the cylindrical body 2, the motor 6, the transfer table 7, the pressing plate 11, the pressing cylinder 10, and the control panel 22 are integrally incorporated in the same body. 1 is configured.
Furthermore, the operation panel 12 provided with operation tools, such as a button switch which performs operation operation of the frozen meat cutting apparatus, is attached to this unit 1.
Therefore, the unit 1 is configured so that frozen meat can be cut if it is supported on a later-described pedestal and a power source and a high-pressure air source are connected by appropriate wiring and piping.

Next, the configuration of the gantry that supports the unit 1 will be described. As shown in FIGS. 1 and 2, the gantry 13 in the first embodiment is formed in a frame shape with a circular pipe made of a relatively large diameter steel material.
That is, the circular pipe is formed in an arch shape, and the front column 14 is closed by connecting the open side (lower side) with a stay 15a made of a circular pipe of the same size, and the circular pipes are arranged on the left and right. Then, the rear struts 14a connected to each other with the stay 15a and standing in the shape of an H are erected at an interval in the front-rear direction. Connect to form a frame.

  The reason why the circular tube is used in this way is not only because of the strength, but also because the pieces of meat scattered during the operation do not accumulate on the surface and the cleaning is easy. The grounding tool 16 is attached to the bottom four places of the support columns 14 and 14a so that the vertical adjustment is possible.

  In this embodiment, the gantry 13 may be equipped with an air compressor (not shown) that supplies high-pressure air to the pressing air cylinder 10 or an air cylinder that connects the unit 1 and the gantry 13 described later. The gantry 13 is a frame that has no walls surrounding it and is open on all sides, unlike the conventional machine.

  When the air compressor is permanently installed in the factory or the like, when the air compressor dedicated to the cutting machine is not required, the gantry 13 is configured only with a frame as a pedestal for the unit 1.

The coupling relationship between the unit 1 and the gantry 13 in the first embodiment configured as described above will be described.
Support pieces 18 and 18 each having a pin hole are attached to a part of the bottom of the unit 1.
On the other hand, support pins 19 and 19 are attached to the upper surface of the front strut 14 located on the front side (left side in FIG. 1) constituting the gantry 13 in a direction parallel to the axis of the cylindrical body 2 with a space left and right. It has been.
By loosely fitting the pin holes of the support pieces 18, 18 of the unit 1 into the support pins 19, 19, the unit 1 and the mount 13 are connected.

  On the other hand, the upper surface of the rear column 14a formed in a round tube in an H shape is covered with the unit 1 as a receiving surface.

  Further, as shown in FIG. 1, the position rearward (right side in FIG. 1) from the support pin 19 of the unit 1 and the mount 13 are connected by a rocking air cylinder 20, and by expanding and contracting the air cylinder 20, The unit 1 moves between the work position where the frozen meat indicated by the solid line in FIG. 1 is cut and the frozen meat input position indicated by the phantom line in FIG. 1 where the transfer table 7 is lower than the work position. In order to be able to do so, it is supported by the gantry 13 so as to be swingable around the axis of the support pins 19 and 19.

  The frozen meat cutting operation position in the unit 1 is normally set so that the frozen meat placement surface of the transfer table 7 is inclined downward about 10 degrees from the horizontal position toward the cylindrical body 2 side. The tilt of the frozen meat placement surface of the transfer table 7 is set to an appropriate tilt state from the vicinity of the horizontal position within a range that does not hinder the relationship between the discharge port 3a and the receiving portion of the meat pieces to be discharged. The unit 1 can be moved and set freely.

  In the present invention, the pressing plate 11 that presses the frozen meat toward the cylindrical body 2 is provided. Therefore, even if the transfer table 7 has a small inclination, for example, near the horizontal position is selected as the cutting work position of the unit 1, it is frozen. There is no obstacle to the transfer of meat.

  The frozen meat cutting operation position in the unit 1 may be fixed at a predetermined position. During the operation, the frozen meat cutting position is directed toward the cylindrical body 2 of the unit 1 according to the amount of frozen meat to be cut. It is also possible to adjust the pressure applied to the cutting blade by the weight of the frozen meat by gradually increasing the slope of the forward drop.

  On the other hand, in the unit 1 where the frozen meat is loaded, the unit 1 is moved so that the frozen meat placement surface of the transfer table 7 is lower than the aforementioned working position. However, it is freely selected and set within the range of the state where it is inclined downward (right side in FIG. 1) from the vicinity of the horizontal position.

Reference numeral 21 denotes an auxiliary frozen meat table placed on the side of the transfer table 7. After the frozen meat is placed on the table, the cover 8 is opened and charged from the side of the transfer table 7.
In the present embodiment, the frozen meat can be input from either the side of the transfer table 7 or the rear as described above, due to the facility layout of the factory.

  23 is a trolley wagon (transfer container) which receives the cut piece of meat and carries it to the next process. In addition, although not shown, there is also a method of receiving a cut meat piece by placing a hopper of a known vertical spiral conveyance device facing the cut-out port 3 of the cut piece of the unit 1.

  Next, a second embodiment will be described with reference to FIG. The mount 13 in this embodiment is a chopper with a mixer.

  The chopper with a mixer itself is a well-known one, and a detailed description is omitted. However, the meat pieces supplied from the mixing tub (stirring and mixing tank) 24 are pumped and shredded with a rotary blade to form a mince from the perforated plate. It has a chopper portion 25 to be extruded, and is configured in a box shape with a drive motor and the like built therein.

  In the mixing tab 24, although not shown in detail, a pair of stirring paddles 26 are usually mounted, and the meat pieces cut at different parts in the tab, the additive to be added, etc. are stirred and mixed by appropriately rotating in the forward and reverse directions. It is the structure sent to the chopper part 25 later.

Support pins 19 for swingably supporting the unit 1 configured as described above are attached to the upper left and right positions of the chopper with a mixer.
The support pin 19 is provided at a position where the discharge port 3 of the meat piece cut by the unit 1 can face the opening of the mixing tab 24 in a direction parallel to the axis of the cylindrical body 2.

  The unit 1 and the chopper with a mixer are connected by a swinging air cylinder 20 as in the first embodiment. By expanding and contracting the air cylinder 20, the unit 1 is swung around the support pin 19, and the unit 1 is moved. It is possible to move between a working position (solid line display position in FIG. 3) and a frozen meat charging position (virtual line display position in FIG. 3).

At the charging position of the frozen meat in the unit 1 configured as described above, the frozen meat placed on the rear supply table 9 inclined backward is moved slowly to the transfer table 7 by its own weight. Slide it in. Since the frozen meat slides on the transfer table 7 having a relatively gentle inclination and arrives at the outer peripheral surface of the cylindrical body 2, the input frozen meat in the configuration shown in the design document 1 has a steep transfer table. There is little concern that the top will fall at once and suddenly collide with the outer peripheral surface of the cylindrical body 2 to damage the cutting blade.
For the sake of safety, the frozen meat is once placed on the rear supply table 9 and manually pushed when the unit 1 moves to the vicinity of the horizontal position. It is also possible to move the unit 1 to the working position after moving the meat to the cylinder 2.

In the configuration shown in the design document 1, cutting is performed when the frozen meat thrown into the inclined transfer table (guide cylinder) at a relatively high position is cut by a dedicated lift device and the operation is interrupted. It is not easy to take out frozen meat on the way.
According to the second embodiment described above, when the unit 1 is moved to the frozen meat charging position and the pressing plate 11 is moved backward, the frozen meat that was being cut also descends while being supported by the pressing plate 11. The cover 8 can be opened and removed easily at the stop position.

  In the chopper with a mixer, the meat pieces cut at different parts are quantitatively charged into the mixing tab 24, mixed with the paddle 26, and then sent to the chopper unit 25. In the frozen meat cutting apparatus in the previous process, the amount of cutting is quantitative. When it reaches, the cutting operation must be interrupted and replaced with frozen meat from different parts. According to the second embodiment as described above, it is extremely useful because it is possible to easily take out frozen meat in the middle of cutting and input frozen meat at different parts.

Moreover, in Design Document 1, when the frozen meat is lifted and put into the frozen meat inlet of the frozen meat cutting device by the lift device, the frozen meat placement surface of the lift device gradually inclines from the middle of the lifting, so The melted meat juice flows down from the front end of the mounting surface and contaminates the surrounding area.
In the second embodiment, since the frozen meat moves while being placed on the transfer table from the loading position to the working position, there is no concern.

  Naturally, it is also possible to combine the units 1 in the same manner as described above using a mixer provided with the mixing tab 24 or a chopper with a hopper instead of the chopper with a mixer.

  In addition, in the configuration of the second embodiment, unlike the configuration in which a cutting device and a lift device for lifting frozen meat are incorporated in the same machine as shown in Design Document 1, a conventional chopper, mixer, and mixer It can be set as the structure which added the cutting function in combination with the unit 1 by adding a part change with respect to an attached chopper.

1 is a side view of a first embodiment according to the present invention. The front view of FIG. The side view of the 2nd example concerning the present invention.
