The present invention is characterized in that a fixed or movable cutting blade is provided for cutting the binding cord of the bundled baggage at the raised part. A second aspect of the invention is that, in the apparatus of the first aspect, a gripping member that can be opened and closed and can grip the binding string of the bundled luggage is provided near the protrusion of the second support frame. Features.

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

In FIG. 1, reference numeral 1 denotes a load placement point such as a conveyor device, and the load M tied with a binding string R is cut on this placement point 1.0 Luggage placement point 1 is It may be a simple fixed platform or a flat part that forms part of a chute, but in the illustrated example, a conveyor device plays that role (i.e., in the illustrated example, bundled loads M are conveyed one after another by an endless conveyor bell) la. The binding string R is then sent to the required position of the cutting device, and the binding string R is cut and removed.

The baggage M whose binding string R75Z is cut by the cutting device of this invention is one that is stacked horizontally like books (
In this specification, the object is a bundle of loaded items (referred to as "loaded items m").

A suitable support frame 2.2 is placed above the cargo storage area 1.
A guide frame 3 fixed to the conveyor device 1 is provided across the loading location, that is, the conveyor device 1, and the guide frame 3 includes a first
The support frame 4 and the second support frame 5 are each movably suspended via a trochanter 4as5a. The guide frame 3 is provided with a hydraulic piston cylinder device or other arbitrary drive device 6.7 provided between the guide frame 3 and the guide frame 3 so that the guide frame 3 can reciprocate in the longitudinal direction. As shown in FIG. 2, front plates 4b and 5b are fixedly attached to the opposing portions of the first support frame 4 and the second support frame 5, respectively, and each front plate 4b or 5b has at least a series of horizontal plates. The protrusion 8.81 or 9.91 is fixedly installed. These protrusions are
As shown by the chain lines in FIG. 1, when the first and second support frames 4.5 are placed close to the sides of the bundled cargo M during the day shift, a part of the loaded cargo M is pressed and shifted, causing the binding string to move. Since the purpose is to lift R from the side surface of a part of the loaded product m, the protrusion 8.81 on the first support frame 4 and the protrusion 9 on the second support frame 5
．． Each protrusion shall be provided at different heights in the vertical direction from 91. In order to avoid damaging the loaded items mf as much as possible, each protrusion is preferably made of synthetic resin, which is softer than metal. Each series of protrusions may be provided intermittently or continuously,
Furthermore, since the protrusions 81.91 are provided auxiliary to ensure the displacement of the loaded items m, at least only the main protrusions 8.9 should be provided. As shown in FIG. 2, near the protrusion 8 of the first support frame 4 described above, there is a cutting blade for cutting the binding string R on the bundled cargo M at the raised portion R6.

It stands out.

Further, the protruding portion of the cutting blade 10 can be inserted into a guide groove 8a provided in an opposing portion of a series of protrusions 8 divided at the center. When it reciprocates, the starting and ending ends of the section are inserted into and guided by the aforementioned guide groove 8a.

The movable cutting blade 10 in the illustrated example cuts the floating binding cord R6 by linear reciprocating motion, but when the cutting blade is moved relative to the first support frame 4, the movement is The movement is not limited to a straight line; for example, it may be oscillated.

As mentioned above, the second support frame 5 plays the role of shifting a part of the loading height m when pressed together with the first support frame 4 in close proximity to the bundled luggage M on the luggage storage area 1. However, the support frame 5 may be provided with a means for grasping the binding string R cut by the cutting blade 10 on the first support frame 4 and removing it from the apparatus.

That is, as shown in FIG. 3, in the vicinity of the protrusion 9 of the second support frame 5, a gripping member 14 which can be opened and closed and can grip the binding string R at the raised portion Ro is provided. 14 gripping members, the second support frame 5 or the fixed mounting plate 5c on the second support frame 5

In FIG. 3, reference numeral 16 indicates a mounting piece fixed to the tip of the rod of the piston cylinder device 15, and 17 indicates a guide rod inserted through the mounting piece 16 so that the mounting piece 16 moves straight. On the drawing,
A part of the guide rod 17 is omitted. The mounting piece 16
is a window or groove 5d opened in the front plate 5b of the second support frame 5.
The above-mentioned gripping member 14, which has a V-shaped tip so as to easily catch the binding string Rt, is fixedly attached to the tip of the gripping member 14, which is made to protrude forward through τ. Further, the gripping member 14 is inserted into a guide groove 9a provided in an opposing portion of a series of protrusions 9 divided at the center. When this gripping member 14 is moved in the direction of the arrow in FIG.
As shown in the figure, the raised portion R6 of R1 is also held between the V-shaped tip and the opposite inverted V-shaped end of the protrusion 9.

Next, the operation of the main part of the present invention having the above structure will be explained.

As shown in FIG. 1, when the bundled cargo M is transported to a required position 1 where the first support frame 4 and the second support frame 5 face each other by a conveyor device or the like, the first and second support frames 4 .5 is the drive device 6.
7 moves in the directions of arrows A and 13, respectively,
It approaches the bundled luggage AI as shown by the chain line. At this time, the protrusions 8.81.9.91 on both support frames 4.5 press the sides of the bundled luggage M, and the loading height n1 of the books, etc. that constitute the luggage M
, and the part t (9) of the binding string R is lifted from the side of the loading height m. As shown, the p1 cutting blade 1.0'fr is moved in the direction of arrow C, that is, from the position of the solid line to the position of the chain line, by operating the 11 drive devices of the first support frame 4''. , cut the raised portion R6 of the binding string R. Therefore, the string R that had formed a ring shape and bound the cargo M is released from its state.

After cutting the string R, the cutting blade 10 is returned to its original position indicated by a solid line by a drive device 11.
Almost at the same time or in parallel with the operation of , as shown in FIGS. 3 and 4, the gripping member 14 is moved in the direction of the arrow by activating the drive device 15 on the second support 5, The raised part R of the binding string R between the opposite end of the protrusion 9
Let them grab the o. Then, when the first support frame 4 and the second support frame 5 are returned to their original positions by the drive device 6.7, the string R released from the annular state is pulled, and the intermediate part is placed on the second support frame 5. As the second support frame 5 returns, it moves away from the loading height m and moves to the side of the cutting device (
(right side in Figure 1) ○ After that, the gripping part 1
When returned to the original position by the 4ffi drive device 15, the binding string R is released from the gripping member 14 and is attached to the lower string receiver 1.
The baggage M1 from which the string Re has been removed in this way, that is, the loading height m, is moved to Kube by a conveyor device or by a conveyor. At this point, each part of the cutting device has returned to its original position, so the cutting device is in a standby state for receiving the next bundled cargo M.

At the final stage of the above-mentioned binding string removal operation, when the second support frame 5 is retreated and the gripped string R is dropped out of the cutting device,
Due to the installation space, it may not be possible to set the retreat position (standby position) of the second support frame 5 sufficiently far apart. In such a case,
When the grip portion 14 on the second support frame 5 is released, the cut end of the string R remains in the cargo placement area 1, and the string R
may get caught and cause trouble in the next operation of the cutting device. Therefore, in the above-mentioned cutting device, the gripping member 1
A removing device 19 can be attached to ensure that the string Re to be removed from the device 4 is removed to the outside of the device. The removal device 19 in the illustrated example includes a removal arm 19a that rotates when necessary between the retreat position (self-help standby position) of the second support frame 5 and the load placement location 1 such as a conveyor device, and a removal arm 19a that rotates at one end.
and fix it to the side frame and other fixing members 1b of the conveyor device 1.
