Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bag binding part cutting device for a bag-like article, which is used for cutting the binding part of a casing filled with ham, sausage, etc.

Hams, sausages, and the like are manufactured by filling a hard tube-shaped membrane called a casing with raw materials and binding both ends of the casing with wire or the like.

FIG. 1 shows this state, where 1 is a casing, 2 is a ham, sausage, etc., and 3 is a binding part using wire or the like.

However, after manufacturing, when packaging ham, sausage, etc. for shipping, it is necessary to cut off the binding portion 3.

The inventors of the present invention have already disclosed in Japanese Patent Application Laid-Open No. 116542/1982 a device for cutting the binding portion of a bag body such as a casing, which efficiently cuts the binding portion of a bag body such as a casing using a pair of blades whose cutting edges are moved toward and away from each other. is suggesting.

However, this conventional device has the disadvantage that if the binding part 3 is sunk into ham, sausage, etc., the binding part 3 cannot be cut off properly.

The present invention was made to solve the above-mentioned conventional drawbacks, and even when the binding part of the bag body such as a casing is sunk into the contents side of a bag-like article such as ham or sausage, It is an object of the present invention to provide a bag body binding part cutting device for a bag-like article that can successfully cut off the binding part.

The present invention will be explained below based on embodiments shown in the drawings.

In Figures 2 to 9, a frame 5 is attached to the front end of the base plate 4, and four rods are fitted in the frame 5 in a direction parallel to the base plate 4, as shown in Figure 3. A hole 6 is provided.

A rod 7 is fitted into each of the rod fitting holes 6 so as to be slidable in the axial direction.

A receiving plate 8 is attached to the front end of each rod 7,
A switch pressing plate 9 is attached to the rear end.

A tapered binding part insertion hole 10 is provided in the plate 8 of the receiver.

Each of the rods 7 is provided with a collar 11 as shown in FIG. 3, and a spring 12 is interposed between the collar 11 and the front end of the frame 5. (3rd
(left side of the figure).

An air cylinder 13 is attached to the rear end surface of the base plate 4, and one end of two levers 15 is rotatably supported at the tip of a rod 13a of the air cylinder 13 by a pin 14.

A pair of blade support members 1 are attached to the other ends of these levers 15.
6 are rotatably connected to each other by a pin 17, and the middle portion of each blade support member 16 is rotatably supported within the frame 5 by a shaft 18 attached to the frame 5.

The front end of each blade support member 16 projects forward from the frame 5, and a pair of single-edged blades 19 are attached to the front end by bolts 30 with their cutting edges facing each other. ing.

Also, as a result, each cutter 19 has a frame 5 and a plate 8.
and the side surface on the frame body 5 side is in contact with the front end surface of each blade support member 16.

Each of the blades 19 has a slope 19a forming a cutting edge formed on the frame 5 side.

Furthermore, an arm insertion groove 19b is provided on the side surface of each cutter 19 on the side of the frame 5 in a direction perpendicular to the cutting edge.

On the rear end side of each blade support member 16, there is a pair of binding part clamping arms 20 having an abbreviated shape and having spring properties.
The rear ends of the arms 20 are attached with bolts 21, and the distal ends of these arms 20 are inserted into arm insertion grooves 19b.

The vicinity of the tip of each arm 20 is bent to fit the slope 19a to form a slope contact portion 20a.

Further, on the surface of the tip of each arm 20 on the frame body 5 side,
A discrepancy prevention material 22 is attached.

Further, when the switch pressing plate 9 is moved back a certain distance or more, it is pressed by an air switch (not shown) and turns on the switch. When the switch is turned on in this way, the air cylinder 13 Air is supplied to the cylinder, and the rod 13a of the cylinder is extended.

Next, the operation of this device will be explained.

When in the standby state, the rod 13 of the air cylinder 13
a is contracted, and as shown in FIG. 7, each blade support member 1
Since the tip side of 6 is open, each blade 19
The cutting edges are widely spaced from each other.

In this state, the tip of each arm 20 protrudes from the cutting edge of each cutter 19.

Next, with the casing 1 filled with the ham etc. 2 and the binding part 3 inserted into the binding part insertion hole 10, the receiver is brought into contact with the plate 8, and then moved relatively toward the frame body 5 for a predetermined distance. When moved, the switch pressing plate 9 retreats together with the plate 8 and rod 7, turning on the air switch.

Then, the rod 13a of the air cylinder 13 is extended,
This movement of the rod 13a is further transmitted to the blade support member 16 via the lever 14, so that the blade support member 16
is rotated in the direction of arrow P in FIG.

Then, the distal ends of the arms 20 move closer to each other, and at a certain point, they clamp the portion 1a of the casing 1 on the distal end side of the binding portion 3.

Then, when each blade support member 16 is further rotated in the direction of arrow P, each arm 20 is deformed so that the angle of the L-shape becomes an acute angle, and the slope contact portion 20a is attached to the blade along the slope 19a. It is moved in a direction away from the cutting edge of No. 19.

Furthermore, when the cutting edges of the respective blades 19 are finally brought into contact with each other, the slope abutting portion 20a is separated from the slope 19a (at this time, the tip of each arm 20 continues to clamp the portion 1a). are doing).

Therefore, between the time the tip of each arm 20 pinches the portion 1a and the time the cutting edges of the blades 19 come into contact with each other, the tip of each arm 20 is holding the portion 1a as shown in FIG. It will move backwards as shown by arrow Q.

For this reason, as shown in FIGS. 7 and 8, the binding part 3
Even if they are recessed into the side, the binding portion 3 will be pulled out from the ham etc. 2 side to the frame 5 side as shown in FIG. So,
As desired, a portion of the casing 1 slightly inside the binding portion 3 is always cut by each blade 19,
There is no risk that the portion 1a will be cut or that the cutting edge of each cutter 19 will hit the wire or the like of the binding portion 3.

The misalignment prevention material 22 is provided to prevent a situation in which when the tips of the arms 20 are brought close to each other, the image tips become misaligned and the portion 1a is not properly held. .

Further, in the embodiment described above, the binding part holding arm 20 is attached to the blade support member 16 that supports the blade 19, but in the present invention, it is also possible to attach the binding part drawing arm to the blade itself.

Furthermore, although the above-mentioned embodiment is an example in which the present invention is applied to a device for cutting off the binding part of a casing filled with ham, sausage, etc., the present invention can also be applied to a binding part of a bag body of other types of bag-like articles. Needless to say, the present invention can also be applied to devices that cut out.

As described above, the bag body binding part cutting device for bag-like articles according to the present invention attaches a binding part clamping arm having a spring property to a pair of blades or a member such as a blade support member that moves together with these blades, and Before cutting the bag binding part with a knife, the binding part is pulled out from the contents side of the bag-like article by each of the arms, so that the binding part sinks into the contents side of the bag-like article. Even in such a case, there is a risk that the bag body may be cut by the blades on the outside of the binding part, or the edges of the blades may hit the wires, etc. of the binding part. This provides an excellent effect in that the binding portion can always be neatly cut off.
