(d) Means for Solving the Problem The binding cord cutting device of the present invention is driven to the side of a baggage placement area such as a conveyor device so that it can approach or separate from the sides of the bundled baggage on the baggage placement area. A first supporting frame and a second supporting frame, both of which are movable, are provided opposite to each other, and a binding string is provided at the opposing portion of the first supporting frame and the second supporting frame to displace a part of the loaded items in the bundled baggage. Protrusions are provided at different levels on the upper and lower sides for lifting the cargo from the side surface of the loaded product, and near the protrusions of the first support frame,
The present invention is characterized in that a fixed or movable cutting blade is provided for cutting the binding string of the bundled baggage at the raised part. Further, a second invention provides the first invention.
The device according to the invention is further characterized in that 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.

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

In FIG. 1, reference numeral 1 denotes a place where a load is placed such as a conveyor device, and a load M bound with a binding string R is cut at the place 1 where the string R is cut. The loading point 1 can be simply a fixed platform or a flat part forming part of a chute, but in the illustrated example a conveyor device plays this role. That is, in the illustrated example, the bundled cargo M is sent one after another to the required position of the cutting device by the endless conveyor belt 1a, and the binding string R is cut and removed.

Above the mentioned loading point 1, a guide frame 3, which is fixed to suitable support frames 2, 2, is provided across the loading point, i.e. the conveyor device 1; , a first support frame 4 and a second support frame 5 are movably suspended via trochanters 4a and 5a, respectively.

The first support frame 4 and the second support frame 5 are provided so as to face the sides of the cargo placement area 1, and are provided between the guide frame 3 and the fluid piston cylinder device or other arbitrary drive devices 6, 7. This allows the guide frame 3 to reciprocate in the longitudinal direction.

As shown in FIGS. 1 to 3, front plates 4b and 5b are fixedly attached to the opposing parts of the first support frame 4 and the second support frame 5, respectively. At least a series of protrusions 8, 81 or 9, 91 are fixed in the horizontal direction. These protrusions press a part of the loaded goods m when the first and second supporting frames 4 and 5 are moved close to the side of the bundled goods M, as shown by chain lines in FIG. Since the purpose is to move the binding string R upward from a part of the side surface of the loaded product m, the protrusions 8 and 81 on the first support frame 4 and the second support frame 5
The upper protrusions 9 and 91 are provided at different levels in the vertical direction (up and down). Each protrusion is preferably made of synthetic resin, which is softer than metal, in order to avoid damaging the loaded items m as much as possible. Each series of protrusions may be provided intermittently or continuously,
Furthermore, since the protrusions 81 and 91 are provided auxiliary to ensure the displacement of the loaded items m, at least the main protrusions 8,
It is sufficient to provide only 9.

Near the protrusion 8 of the first support frame 4 described above, there is a second
As shown in the figure, a cutting blade 10 is provided for cutting the binding string R on the bundled cargo M at the raised portion _R0 . The cutting blade 10 can be provided fixedly or movably with respect to the first support frame 4. When the cutting blade is fixedly provided (not shown)
The first supporting frame 4 may be provided near the front plate 4b so that the raised string R ₀ touches the cutting edge at the final stage of forward movement. In the illustrated example, a cutting blade 10 is movably provided with respect to the first support frame 4 . The cutting blade 10 is horizontally reciprocated by a piston cylinder device or other drive device 11 attached to the first support frame 4 or a fixed mounting plate 4c on the first support frame 4. In FIG. 2, 12 is a mounting piece fixed to the tip of the rod of the piston cylinder device 11, and 13 is a guide rod inserted through the mounting piece 12 so that the mounting piece 12 moves straight. In the drawing, a part of the guide rod 13 is omitted. Binding string R
A V-shaped cutting blade 10 that makes it easy to capture
is fixed to the mounting piece 12 and protrudes forward from a window or groove 4d opened in the front plate 4b of the first support frame 4. Further, the protruding portion of the cutting blade 10 is configured to be inserted into a guide groove 8a provided in an opposing portion of a series of protrusions 8 divided at the center.
Therefore, when the cutting blade 10 reciprocates with the piston-cylinder device 11, it is inserted into and guided by the guide groove 8a at the beginning and end of the section.

The movable cutting blade 10 in the illustrated example cuts the floating binding cord R ₀ by linear reciprocating motion, but when the cutting blade is made movable with respect to the first support frame 4, The movement is not limited to linear movement; for example, it may be oscillated.

As mentioned above, the second supporting frame 5 is located at the cargo loading area 1.
When pressed together with the first support frame 4 in close proximity to the bundled cargo M above, it plays the role of shifting a part of the loaded goods m. It is possible to provide a means for grasping the binding cord R cut by the cutting blade 10 and removing it from the apparatus.

That is, in the vicinity of the protrusion 9 of the second support frame 5, the third
As shown in the figure, the raised part of the binding string R
A gripping member 14 that can be opened and closed and can be gripped at R ₀ is provided. The gripping member 14 can be horizontally reciprocated by a piston cylinder device or other drive device 15 attached to the second support frame 5 or a fixed mounting plate 5c on the second support frame 5. In FIG. 3, 16 is a mounting piece fixed to the tip of the rod of the piston cylinder device 15, and 17 is a guide rod inserted through the mounting piece 16 so that the mounting piece 16 moves straight. In the drawing, a part of the guide rod 17 is omitted. The mounting piece 16 protrudes forward through a window or groove 5d opened in the front plate 5b of the second support frame 5, and has a V-shaped tip at its tip so as to easily catch the binding string R. The above-mentioned gripping member 14 formed in the above-mentioned shape is fixedly provided. In addition, the gripping member 14
are inserted into guide grooves 9a provided in opposing portions of a series of protrusions 9 divided at the center.
When this gripping member 14 is moved in the direction of arrow D in FIG. 3, as shown in FIG. Let's grasp the raised part R ₀ of the binding string R by pinching it.

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

As shown in Figure 1, the first
When the bundled cargo M is carried to the required position 1 where the support frame 4 and the second support frame 5 face each other, the first and second support frames 4 and 5 are moved by the actuation of the drive devices 6 and 7, respectively. It moves in the directions of arrows A and B and approaches the bundled cargo M as shown by the chain line. At this time, the protrusions 8, 81, 9, 91 on both support frames 4, 5 press the side surface of the bundled baggage M, shift a part of the loaded items m such as books that make up the baggage M, and tighten the binding string. A part of R is loaded with R ₀ .
Lift it up from the side. Bundled baggage M in Figure 1
indicates this state. Here, as shown in FIG. 2, by operating the drive device 11 on the first support frame 4, the cutting blade 10 is moved in the direction of arrow C, that is, from the position of the solid line to the position of the chain line,
Cut the raised part _R0 of the binding string R.
Therefore, the string R, which had formed into a ring shape and bound the cargo M, is released from its state. The cutting blade 10 is a string R
After cutting, the drive device 11 returns it to the original position shown by the solid line.

Further, as shown in FIGS. 3 and 4, approximately at the same time or around the same time as the operation of the cutting blade 10, a second
By activating the drive device 15 on the support frame 5, the gripping member 14 is moved in the direction of arrow D, and the raised portion _R0 of the binding string R is gripped between it and the opposite end of the protrusion 9. Then, the first support frame 4 and the second
When the support frame 5 is returned to its original position by the drive devices 6 and 7, the string R released from the annular state
is separated from the loaded product m as the second support frame 5 returns to the side of the cutting device (as shown in FIG. right side). Thereafter, when the gripping member 14 is returned to its original position by the drive device 15, the binding string R is released from the gripping member 14 and falls to the lower string receiver 18 or the like. The cargo M from which the string R has been removed in this way, that is, the loaded product m, is moved to the outside by a conveyor device or by hand. At this point, each part or member 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.

(f) Example At the final stage of the above-mentioned binding string removal action, the second
When the supporting frame 5 is retreated and the gripped string R is dropped out of the cutting device, it may not be possible to set the retreated position (standby position) of the second supporting frame 5 sufficiently far apart due to the installation space. In such a case, when the gripping member 14 on the second support frame 5 is released, the end of the cut string R remains in the load placement area 1, and the string R is caught and the next cutter of the main cutting device is It may cause problems in operation, etc. Therefore, the above-mentioned cutting device can be provided with a removing device 19 for reliably removing the string R that is about to fall from the gripping member 14 to the outside of the device. The illustrated removal device 19 has a second
A removal arm 19a rotates when necessary between the retracted position (initial standby position) of the support frame 5 and the load placement location 1 of the conveyor device, etc., and a removal arm 19a whose one end is fixed to the removal arm 19a and is attached to the side frame of the conveyor device 1. Other fixing members 1b
A rotating shaft 19b rotatably supported by the rotating shaft 19b, a pinion 19c fixed to the other end of the rotating shaft 19b, and a piston cylinder device 1 that meshes with the pinion 19c.
Rack 19e made to reciprocate by 9d
The removal arm 19a is connected to the second supporting frame 5.
The upper gripping member 14 is opened and the string R is rotated at approximately the same time or in tandem with the action of releasing the string R, thereby making it possible to more reliably remove the string R to the outside.

In the figure, numerals 20 and 21 indicate sensors that determine the standby positions of the first support frame 4 and the second support frame 5, respectively, and 22 indicates a sensor that determines the desired amount of deformation when shifting a part of the bundled cargo M. 23 indicates a sensor for confirming the gripping action of the binding string R by the gripping member 14.

In addition, in the above-mentioned operation of the cutting device of the present invention, the processing of the cargo M in which the loaded items M are tied at only one place has been explained, but for example, the processing of the cargo M in which the loaded items M are tied at two places (vertically and horizontally) in a cross shape is explained. When processing baggage, the bundled baggage can be passed through the device of the embodiment twice in different directions, or the device of the example can be installed vertically and horizontally and the tied baggage can be passed through the device twice. A method of cutting and removing may also be adopted. Furthermore, in the apparatus of the embodiment, a turntable may be provided at the cargo loading area 1 to cut and remove the string in one direction and then rotate the string by 90 degrees to cut and remove the string in the other direction. Alternatively, it is also possible to adopt a method in which the guide frame 3 on which the second support frame 5 and the like are suspended is rotated by 90 degrees to sequentially cut and remove the vertical and horizontal binding strings.

(G) Effects of the Invention According to the device for cutting ties for bundled luggage according to the present invention described above, the ties R can be quickly and automatically cut and removed without substantially damaging the loaded items m of the bundled luggage M. Therefore, bundled luggage M
This has the effect of significantly streamlining the release work. In particular, in the present invention, both the first support frame 4 and the second support frame 5 which are brought into contact with the side surface of the bundled luggage M are movable, and also, a part of the loaded items m in the bundled luggage M can be shifted. In addition, in order to lift the binding string R from the side of the loaded items m, the protrusions 8 and 9 provided on the first support frame 4 and the second support frame 5 are arranged at different heights, so that books and other items can be loaded. The bottom surface of the bundled cargo M made up of the items m is hardly shifted or moved on the cargo placement area 1, and damage to the loaded items m during the cord cutting operation is almost completely prevented, In addition, the position of the bundled cargo M does not change before and after the binding string R is cut, and for example, even after the string is cut, the bundled cargo M can be placed in the center of the conveyor device, and the subsequent processing of the loaded cargo M is possible. This will be extremely advantageous.
