The present invention relates to a device for setting a required amount of packing nets.

[Conventional technology]

FIG. 7 and FIG. 8 show the conventional “mesh processing packaging net mounting device” previously devised by the present applicant (Japanese Utility Model Application No. 62).
-34768).

This conventional meat packing packaging device (hereinafter, abbreviated as “mesh mounting device”) 1 is a meat processing packaging net (hereinafter, “packing net”) housed in a roll in a net container 2. (Hereinafter, simply referred to as "3") is a device for mounting the cartridge 3 on the outer peripheral portion of the cartridge 4 in a state of being pulled close to the cartridge 4,
In addition to the cartridge 4, a base 5 for holding the cartridge 4, a plurality of locking claws 6 for locking the packing net 3 in the net container 2 with the net mouth open, and this locking An operating plate 7 for supporting the pawl 6 in a vertically rotatable manner and covering the cartridge 4 with the packaging net 3 in a state of being locked by the locking pawl 6 and guiding it to the base end thereof, and the locking pawl 6 of the cartridge 4. A biasing means 8 for biasing inwardly from the outer diameter, and a biasing means 8 inserted into the tip of the cartridge 4 and contacting the tip of the latching claw 6 when the latching claw 6 is moved toward the cartridge 4. And a cap 9 for guiding the outer periphery of the cartridge to the outer periphery of the cartridge.

According to this net mounting apparatus 1, as shown in FIGS. 9 to 11, by simply moving the operating plate 7 up and down, the required amount of the packing net 3 can be drawn around the outer circumference of the cartridge 4 in a required amount. Can be set.

That is, first, as shown in FIG.
Pull out from, and with its tip open, the locking claws 6,6,
, And then the operation plate 7 is moved toward the cartridge 4 on the base 5 while holding the handle 10. As a result, the packing net 3 is unwound as shown in FIG. 10, and the tip of the locking claw 6 comes into contact with the cap 10 in the middle thereof,
It is guided to the outer circumference of the cartridge 4 along the outer surface of 10. When the operation plate 7 is further moved from this state to the base end of the cartridge 4, the cartridge 4 is inserted into the packaging net 3 and the outer periphery of the cartridge 4 is covered with the packaging net 3 as shown in FIG. Here, when the operation plate 7 is pulled up, the engagement between the wrapping net 3 and the locking claw 6 is released, and the wrapping net 3 is left in a state of being covered with the outer periphery of the cartridge 4 by its elasticity.
Then, when the locking claw 6 (operation plate 7) is moved to the base end side of the cartridge 4 again, since the locking claw 6 is reduced in diameter by the biasing means 8, the locking claws 6, 6 ,. Wrapping net 3 alone
And the packaging net 3 is pulled toward the base end side of the cartridge 4. After that, similarly, only by repeating the vertical movement of the operation plate 7, the packing net 3 is pulled out from the net container 2 and is sequentially drawn to the base end portion of the cartridge 4.

For reference, the use of the cartridge 4 having the packaging net 3 mounted thereon as described above will be described below with reference to FIG.

In FIG. 12, reference numeral 11 is a meat net packing machine for packing meat in a net (hereinafter, abbreviated as “net packing machine”).
The net packing machine 11 is mainly composed of a tubular body 12 formed into a tapered tubular shape as a whole. The cylindrical body 12 is formed, for example, by winding a metal plate in a roll shape, and thus has a little elasticity in the radial direction. Reference numeral 13 is a push rod for pushing out the meat.

In order to net-wrap the meat M, first, the cartridge 4 mounted with the packaging net 3 pulled up as described above is mounted on the cylindrical body 2 with the cap 9 at the tip removed. At this time, the tip of the packaging net 3 is closed by tying it. When the above preparation is completed, the meat M is inserted through the insertion port 12a at the base end of the cylindrical body 12, pushed forward by the push rod 13, and pushed out of the cylindrical body 12 through the extrusion port 12b at the tip of the cylindrical body 12. At this time, the meat M is pushed out while the packaging net 3 that has blocked the extrusion port 12b is pulled. At this time, the packaging net 3 attached to the base end portion of the cartridge 4 in a state of being pulled up is sequentially fed forward. After the meat M is completely pushed out of the cylinder 12,
By cutting the packaging net 3 in the vicinity of the extrusion port 12b, binding the meat M side of the cut portion to complete the packaging of the meat M, and also binding the cartridge 4 side of the cutting portion,
Prepare for the next meat packaging. When packing the next meat,
The packing net 3 drawn up to the base end of the cartridge 4 is sequentially supplied.

In this way, when carrying out the net packing of meat, if the packing net 3 is attached to the cartridge 4 in advance,
Since the packing net 3 is expanded in diameter by the cartridge 4, it is extremely easy to push the meat M into the net and the net feeding becomes smooth. In addition, by preparing a plurality of cartridges 4, they can be diverted one after another, and work efficiency can be improved.

In addition, in the conventional meat net attaching device 1, although the operation plate 7 is configured to be manually operated in the illustrated example, it is configured to be operated by a drive device such as an air cylinder. In some cases.

[Problems to be solved by the device]

By the way, in the above-mentioned conventional net mounting apparatus 1 for mounting the packaging net 3 on the cartridge 4 as described above, it is sure that the packaging net 3 stored in the net container 2 can be efficiently used by the cartridge 4
However, the following points to be improved were left.

That is, in the above-mentioned net attachment device 1, due to its configuration,
Since the operation plate 7 is guided by a plurality of guide columns 14 penetrating the vicinity of the outer peripheral portion thereof, when the operation claw 6 is moved up and down by moving the operation plate 7 up and down, In order to perform a smooth operation, it is necessary to always apply an even force to the handles 10 provided on the left and right sides, which is a tricky operation.

Further, in the net mounting apparatus 1 of the above example, the locking mechanism 16 formed at one end of the lever 15 naturally prevents the operation plate 7 from falling, but the locking claw 6 has a sharp tip, and Since the operation plate 7 is relatively heavy and can move up and down, for example, when the cartridge 4 is installed on the base 5 or when the tip of the packaging net 3 is locked by the locking claw 6. As expected, I had to feel a sense of anxiety about the operation panel 7 falling.

Further, when the operation plate 7 is moved up and down automatically by an air cylinder or the like as described above, the guide column 14
For the same reason that a plurality of air cylinders are required, it is necessary to use at least two air cylinders and it is necessary to synchronize them, resulting in high cost and time and effort for adjustment.

The present invention has been made in view of the above circumstances, and in the meat net attaching device having the above-described excellent action, the above disadvantages can be eliminated, the operation can be facilitated, and the cost can be reduced. Moreover, it is an object of the present invention to provide a meat net attachment device capable of improving safety.

[Action]

The main point of this device is that the engaging claw 6 side is fixed and immovable in the above-mentioned conventional net mounting device 1 while the cartridge side is moved. The basic operation is the above-mentioned net. It is similar to the mounting device 1.

That is, when the packing net stored in the net container is pulled out, the tip of the net is locked by a plurality of locking claws with the mouth of the net being opened, and the cartridge holder in which the cartridge is set is moved upward, On the way, the tip of the locking claw comes into contact with the cap and is guided to the outer periphery of the cartridge along the outer surface of the cap. When the cartridge is further moved upward from this state, the cartridge is inserted into the packing net and the outer circumference of the cartridge is covered with the packing net. After that, when the cartridge is moved downward, the engagement between the wrapping mesh and the locking claw is released, and the wrapping net remains covered with the outer periphery of the cartridge due to its elasticity, and when the cartridge is moved upward again, the locking is performed. The wrapping net is hung on the claws, and the wrapping net covered on the outer circumference of the cartridge is pulled up to the base end portion of the cartridge.

Here, a through hole 23a centered on the axis of the air cylinder 31 is formed in the substantially central portion of the intermediate plate 23, and the air cylinder 31 has the rod 31a in the shortest state. Cartridge holder 26
Is installed at a level such that it comes to a position almost corresponding to the through hole 23a. This air cylinder
31 is a state in which the telescopic rod 31a is most extended,
The cartridge holder 26 has a stroke to reach the proximity position of the locking claw 6, and a continuous expansion / contraction operation is automatically performed by an air control device (not shown).

Further, in the embodiment, a plurality of outwardly projecting locking pieces 32a are provided on the outer peripheral surface of the base end of the cartridge 4 at equal intervals along the circumferential direction, while the cartridge holding body 26 holds them. A holding piece 32b that engages with the piece 32a is provided, and the holding piece 32a and the holding piece 32b constitute a holding mechanism 32 for holding the cartridge 4 in a vertical state. In the holding mechanism 32, the cartridge 4 is rotated in one direction so that the both (the locking piece 32a and the holding piece 32b) are engaged with each other.
However, the holding mechanism is not limited to this example.

The net container 2 for housing the packaging net 3 wound in a coil shape
Is formed in a semicircular box shape, and is fixed in the vicinity of the opening 24a on the top plate 24 with its opening facing upward.

The cap 9 that covers the upper end of the opening of the cartridge 4 is preferably a hemispherical shape as shown in the drawing, but may be a truncated cone shape, for example.

Next, the operation of the meat net attaching device 20 configured as described above will be described.

In order to set the packaging net 3 around the outer circumference of the cartridge 4 in the required amount by the present device 20, the following operation may be performed.

First, as shown in FIG. 1, the telescopic rod 31 of the air cylinder 31.
The cartridge a is retracted to the lowermost position, and the cartridge 4 is vertically attached to the upper portion of the cartridge holder 26 fixed to the tip of the telescopic rod 31a. At this time, the cartridge 4 is
The locking piece 32a is firmly fixed by engaging the holding piece 32b formed on the cartridge holding body 26. In the mesh container 2, a packaging mesh 3 wound in a coil shape is stored.

Then, as shown in FIG.
Pull out through a and open the mouth of the net to lock the weft thread at its tip to each locking claw 6,6, ....

After the above preparations are made, the air cylinder 31 is driven by operating an air control device (not shown).

When the telescopic rod 31a is extended upward by driving the air cylinder 31, the tips of the locking claws 6, 6, ... Abut on the outer surface of the cap 9 as shown in FIG. The tip of each locking claw 6 is guided to the outer periphery of the cartridge 4 along with the shift.

When the telescopic rod 31a is further extended from this state to the uppermost position, the cartridge 4 is inserted into the packing net 3 as shown in FIG.

After that, when the telescopic rod 31a is retracted downward, the packing net 3
Since the portion of the cartridge 4 covered by the cartridge 4 tightens the cartridge 4 by its elasticity,
5 is moved downward and is pulled out downward as shown in FIG. Further, when the cartridge 4 is moved downward, the engagement of the locking claw 6 with the weft yarn of the packaging net 3 is released at the same time.

When the telescopic rod 31a is again extended upward from this state, the cap 9 is moved during the upward movement of the cartridge 4.
When the abutting contact with the tip of the locking claw 6, the weft thread of the packaging net 3 is locked to the tip of the locking claw 6 and covered on the outer periphery of the cartridge 4 of the packaging net 3 as shown in FIG. The part is pulled toward the base end of the cartridge 4.

After that, the above-described operation is repeated by repeating the vertical movement of the telescopic rod 31a as described above, and the packing net 3 becomes the net container 2
The cartridge 4 is mounted while being drawn out from the base end portion of the cartridge 4.

After the wrapping net 3 has been pulled close to the cartridge 4 by a necessary amount, the wrapping net 3 is cut halfway above the cartridge 4 and the cartridge 4 with the wrapping net 3 attached is removed from the cartridge holder 26. It may be set in the net wrapping device 11 as shown in FIG. On the other hand, a net mounting device
Set another cartridge to 20, as shown in Fig. 1,
By the same operation as above, the packing net 3 is also attached to the cartridge.
It can be attached in a state of being pulled up.

As described above, according to the meat net attaching device 20 of the present embodiment, it is needless to say that the packaging net 3 can be surely attached to the cartridge 4 in a state of being pulled close to the cartridge 4, but the locking claw 6 is fixed. ,
Since the cartridge 4 is moved up and down, the center portion of the movable member (cartridge 4) with respect to the moving direction can be supported. For example, even when a guide rod for guiding the up and down movement is provided, It is not necessary to provide a plurality of them, and the vertical movement can be performed extremely smoothly. With respect to this, in the embodiment, the cartridge 4 is operated by the air cylinder 31, but it is clear that the above operation can be obtained even if the cartridge 4 is constructed manually. And
Even if the cartridge 4 is moved up and down by an air cylinder as in the embodiment, it goes without saying that the packaging net 3 is automatically attached by this. According to this, it is possible to realize the above-mentioned action with only one air cylinder, and it is possible to simplify the configuration and reduce the cost associated therewith.

Further, since the cartridge 4 is moved up and down and the locking claw 6 is fixed, it can be hooked on the locking claw 6 of the packaging net 3 as shown in FIG. At the time of setting to 26, etc., the danger that the locking claw 6 will fall by any chance like the above-described conventional mounting device 1 is eliminated, and the safety is further enhanced.

[Effect of device]

As described above, according to the meat net mounting device of the present invention, it is possible to mount the packing net securely on the cartridge, and of course, the locking claw is fixed to move the cartridge up and down. As a result, it is possible to set the point of action of the force of the movable part on the central axis of the disposition position of the locking claw, which eliminates the need to provide multiple guide rods for guiding the up and down movement and facilitates smooth operation. Further, even when the cartridge is configured to be moved up and down by a drive device such as an air cylinder, it is possible to use only one drive device, which simplifies the configuration. The cost associated therewith can be reduced. Furthermore, since the locking claw side is fixed by making the cartridge side movable, the danger that the locking claw will fall during the preparatory work is eliminated, and further improvement in safety can be expected. An excellent effect can be achieved.
