A brake mechanism is provided which can be switched between "brake position".

[0010]

However, the binding device of the packing machine disclosed in Japanese Utility Model Laid-Open No. 6-72808 includes
There are the following problems. (1) The guide bar 10 for locking the binding cord 104
6, the hook-like end 106a at the rear end is open, and is not closed to form a string through hole.
4 may come off from the hook-shaped end portion 106a due to vibration or the like, and the string may be loosened. If the pressing is performed while the string 104 is loosened, the binding string 104 is entangled in the workpiece D, resulting in poor packing. (2) Prior to putting the workpiece D into the box 102, the binding string 104 is guided and set along the above-described route, and the binding string 104 is guided to the guide bar 106.
When the guide bar 106 is engaged with the hook-like end 106a at the rear end, the guide bar 106 is turned by operating the lever 106b at the front end of the guide bar 106 with the other hand while holding the binding string 104 with one hand. Need to be moved. Also, the workpiece D
In order to remove the binding cord from the hook-shaped end 106a at the rear end of the guide bar 106 after the compression of the guide bar 106 is completed, the guide bar 106 is also rotated by operating the lever 106b at the front end of the guide bar 106. It is necessary, and the work is complicated and troublesome. In particular, in the case of an unskilled worker, this work requires more time than necessary. The operation of this type of apparatus is usually performed by unskilled workers who have not been specially trained or trained, which poses a problem. (3) After the workpiece D is discharged out of the box 102 by the tilting of the tilting plate 107, the interlocking shaft 125 and the cylinder 1
21 is disengaged from the engagement hole 123, the tilt plate 1
07 and the tilting mechanism fall under their own weight and collide with the bottom wall of the box 102, so that a loud impact sound is generated and the tilting plate 107 and the tilting mechanism 120 are easily damaged.

The conventional brake mechanism as described above has the following problems. (1) When the brake mechanism is in the “non-brake position”
In order to guide and set the binding string 104 along the route as described above, when pulling the binding string 104 downward by hand, the pulling force is often too strong, and the binding string 104 becomes excessive due to the inertial force. I am pulled out and relax. To remove this slack, rotate the reel 110 in the opposite direction by hand,
It is necessary to rewind the binding cord 104 that has been excessively pulled out, and the operation is complicated and troublesome. Further, in order to prevent such a state from occurring, the work requires careful attention and skill. However, the operation of this type of device is usually performed by unskilled workers who have not received special education and training, which is problematic. (2) Avoid the trouble of setting the binding cord wound in a coil shape on the reel 110 as described above, or
Since it is expensive to purchase the binding string wound on the reel in advance, instead of the above-described reel 110, the tip of the coiled binding string is manually placed on the upper end of the box 102. A box that prevents falling from the upper end of the box 102 even when pulled is fixed, and a binding string wound in a coil shape is placed in this box so that the winding axis is vertical. A binding string supply means capable of pulling out the binding string from the inside has been adopted. Such a binding string supply means does not require the strong force required to rotate the reel 110 as described above in order to pull out the string, and the problem described in the above item (1) is not required. Points are more likely to be triggered. or,
Even with only the own weight of the tying strap hanging down, the strap is pulled out excessively and becomes slack, and extra work is required to remove the slack, leading to a reduction in work efficiency.

The present invention has been made in view of the above problems, and has the following problems. (1) Prevents the binding string from coming off from the locking part on the rear end side of the press plate during the work of compressing the work piece and loosening and getting wrapped around the work piece to cause defective packing. A first object of the present invention is to provide a compression packing device capable of improving the reliability and speed in the above.

(2) When guiding and setting the binding string prior to loading of the object to be processed, a complicated operation using both hands when locking the string at the locking portion on the rear end side of the press plate And the string is naturally released from the locking portion on the rear end side by the weight of the object only by raising the press plate when packing the object after compression. Or, at least, pull the string lightly by hand so that the string can be released from the locking part on the rear end side, so that complicated operations by hand can be omitted as much as possible, and the work process can be simplified. It is not necessary, and also prevents the binding string from coming off from the locking part on the rear end side of the press plate during packing work and causing a packing failure beforehand. A second problem is to provide a compression packing device capable of improving speed. To.

(3) When the main door is closed for compressing the object to be processed, the mechanism for preventing the binding string from coming off from the locking portion on the rear end side is operated, and the unskilled operator presses the press plate. If you forget to operate the mechanism to prevent the binding strap from coming off from the locking part on the rear end side of the press plate, the cord may come off from the locking part on the rear end side of the press plate and cause packing failure. A third object of the present invention is to provide a compression packing apparatus which does not require any skill in the work and can further improve reliability and speed in the work.

(4) Prior to the loading of the object to be processed, the operation of guiding and setting the binding strap to a predetermined route can be performed while always tightening the binding strap. It was wound on a reel or wound in a coil shape, and was placed so that the winding axis was vertical, due to the inertia force due to the excessive downward pulling force, or due to the weight of the binding cord hanging down. The binding cord is not pulled out excessively and becomes slack, and no extra rewinding work is required to remove the slack.Therefore, there is no need for skill in the work, thereby simplifying the work process and improving work efficiency. A fourth object is to provide a compression packing device capable of performing the above.

(5) After the object to be compressed and packed is discharged from the compression chamber due to the tilting of the tilting plate, a loud impact noise due to collision with the compression chamber bottom wall when the tilting plate and the tilting mechanism descends. A fifth object of the present invention is to provide a compression packing device capable of preventing the occurrence of a crack and the damage of the tilting plate and the tilting mechanism.

Since the present invention is configured as described above, when guiding and setting the binding string prior to the loading of the workpiece, the string is locked to the locking portion on the rear end side of the press plate. Without the need for complicated operations using both hands.
Also, when packing the object to be processed, after compressing the object, the weight of the object only causes the string to come off naturally from the locking portion on the rear end side by simply lifting the press plate, or at least lightly hand the string. Just pull it off to remove the string from the locking part on the rear end,
Complicated operations by humans can be omitted as much as possible, the work process can be simplified, the work does not require skill, and the strap for binding is placed behind the press plate during the compression work of the workpiece. It is possible to improve the reliability and speed of the operation by preventing the package from being detached from the locking portion on the end side and causing a defective packing.

In the present invention employing the first technical means or the second technical means, in order to solve the third problem, as a third technical means, the main door and the block member are connected to each other. When the main door is closed, the block member is switched from the unblock position to the block position when the main door is closed, and is switched from the block position to the unblock position when the main door is opened. It is desirable to configure so that.

According to the above construction, since the unskilled operator forgets to operate the mechanism for preventing the binding string from coming off from the locking portion on the rear end side of the press plate, the rear end of the press plate is The strap does not come off from the locking portion on the side to cause a packing failure, the skill is not required for the work, and the reliability and speed in the work can be further improved.

When each of the string through-hole forming members 43 receives the force in the rotational direction from b through the key portion 43a, each of the string through-hole forming members 43 temporarily reaches the “unlatched position” against the urging force of the torsion spring 44. It can be rotated to form a gap X, allowing the binding string 12 to pass through the gap X into the string passing hole 45, and after passing the binding string 12 again by the urging force of the torsion spring 44. A structure has been established that allows X to return to the closed "latch position". On the other hand, the inclined surface 43c is
At the “latch position” after the binding string 12 has been passed through the string passing hole 45, each key 43
When the binding string 12 is strongly pressed (actually pulled outward) between the binding key 12a and the binding key 12a, the binding key 12a receives a force to rotate in a direction away from each other via the inclined surface 43c. . Then, a force in the rotational direction is applied from the inclined surface 43c via the key portion 43a to each of the string through-hole forming members 43.
Is received, each string through-hole forming member 43 is torsion spring 44
Can be temporarily rotated to the “unlatched position” against the urging force to form the gap X, and the binding string 12 is allowed to be removed from the string passing hole 45 from the gap X,
Further, a structure is established in which, after being removed, it is possible to return to the “latch position” where the gap X is closed again by the urging force of the torsion spring 44.

In addition, on the press plate 11, the string passing hole forming member 43 of each rear string guide means 53 is rotated from the "latch position" to the "unlatched position" where the gap X is formed. Is provided, and a block member 55 capable of preventing or releasing this is provided. Block member 55
Is attached to the press plate 11 via the same bracket 41 as the string through-hole forming member 43, and a state in which the tip 55a protrudes between the hook portions 43a and the arm portions 43e on the opposite side with the intermediate portion 43d interposed therebetween. "Block position"
And an “unblocked position” where the tip 55a has retreated from between the arms 43e. or,
A compression coil spring 56 mounted between the other end 55b of the block member 55 and the bracket 41 in a compressed state.
Therefore, the other end 55b is received by the block interlocking portion 57, and the amount by which the block member 55 moves in the retreating direction is regulated. Note that the positions drawn by solid lines in FIGS. 5 and 7 and FIG. 8A show a state in which the block member 55 is arranged at the “block position”. In the state of being placed at this block position, the rotation of the string passing hole forming member 43 is refused by the block member 55 and is always held at the “latch position”, and cannot be switched to the “unlatched position”. That is, the binding string 12 is not taken in and out of the string passing hole 45. On the other hand, the position drawn by a two-dot chain line in FIGS. 5 and 7 and FIG.
Indicates a state in which the block member 55 is arranged at the “unblock position”. This "unblock position"
In this state, the rotation of the string through-hole forming member 43 can be changed from the “latch position” to the “unlatched position” without being blocked by the block member 55. That is, the binding string 12 can be taken in and out of the string passing hole 45.

The block interlocking section 57 has a structure in which an operation of an eject hook mechanism 31 described later is transmitted to the rod 58 via the cam follower 60, and the rod 58 rotates. That is, when the main door 9 is open, the rod 58 rotates together with the cam follower 60 and the operating arm 59 to the position where the block member 55 moves to the “unblock position”, and when the main door 9 is closed, the block member 55 is moved. It is structured to rotate together with the cam follower 60 and the operating arm 59 at a position to move to the “block position”.

According to the configuration of the embodiment of the string guide mechanism 14 for binding the press plate 11 and the press plate according to the second aspect, the string guide for binding the press plate 11A and the press plate according to the first aspect. As compared with the configuration of the embodiment of the mechanism 14A,
It has the following excellent functions and effects. That is, if the urging force of the torsion spring 44 for urging the pair of string through-hole forming members 43 of the rear string guide means 53 in the “latch position” direction is appropriately selected, (1) opening the main door 9 When the string 12 is guided and set along the same route as above,
When the string 12 is locked at the “latch position”, a pair of the string through-hole forming members 43 of the rear guide 53
The string can be easily inserted into the string passing hole 45 only by strongly pressing the binding string 12 from below to between the key portions 43a at the lower end of the strap. (2) After the object D is compressed, when the press plate 11 is raised to pack the object with the string 12 with the main door 9 opened, the load of the object D acting on the string 12 is increased. As a result, the string 12 is pulled downward, and the string 12 naturally comes out of the string passing hole 45, so that the operator does not need any operation for removing the string.
Even if the urging force of the torsion spring 44 is too strong and the string 12 does not fall out of the string passing hole 45 naturally due to the load of the workpiece D, if the worker pulls the string 12 obliquely downward, The string 12 can be easily removed from the string passing hole 45. Further, the object to be processed D is similar to the operation and effect of the embodiment of the string guide mechanism 14A for binding the press plate 11A and the press plate according to the first and third embodiments.
When the main door 9 is closed for the compression process, the block member 55 is switched to the “block position” as described above, and the switch from the “latch position” to the “unlatched position” of the rear string guide unit 53 is performed. Will be blocked,
Even if the press plate 11 is repeatedly lowered and raised during the compression work, it is possible to prevent the string 12 from coming off from the rear guide means 53 due to vibration or the like, loosening, and being wrapped around the workpiece D, thereby causing defective packing. You.

Next, a description will be given of a cord pull-out brake mechanism 25 according to a fourth embodiment of the present invention.
9 and 10 are views showing the configuration and operation of the string pullout brake mechanism 25, and FIG. 9 shows a "half brake position" described later.
(A) is a cross-sectional view taken along the line GG of (b), (b) is a cross-sectional view taken along the line FF of (a), and FIG. (A) is (b)
(B) is a sectional view taken along line FF of (a).

9 and FIG.
As shown in FIG. 0, the box 2 is fixed to the inside of the front wall 2fw at the top of the box 2 via fixing bolts 26b.
an upper guide plate 26 having an L-shaped vertical section and having a rectangular through hole 26sh at the center of the horizontal portion on the fw side;
A pair of spacer plates 29 whose upper surfaces are in contact with the lower surfaces near both ends in the width direction {vertical direction of the paper surface of FIGS. 9 (a) and 10 (a)} and which are arranged at a predetermined interval; A plane provided with the lower surface of the spacer plate 29 so as to contact the upper surface near both ends in the width direction, and having a square notch 27sn at the center on the front wall 2fw side so as to correspond to the through hole 26sh of the upper guide plate 26. A U-shaped lower guide plate 27,
The lower guide plate 27, the pair of spacer plates 29, and the four bolts 25b that penetrate the upper guide plate 26 up and down to connect and fix them together form a main body.

The space defined by the lower surface of the upper guide plate 26, the upper surface of the lower guide plate 27, and the inner surface in the width direction of the pair of spacer plates 29 of the main body of the cord pull-out brake mechanism 25 includes:
The thickness of the upper guide plate 2 is thinner by a predetermined thickness than the thickness of the spacer plate 29 and is farther from the inner surface of the front wall 2fw.
6, a rectangular through hole 28sh of the same width is provided at the same position as the width direction position of the rectangular through hole flat surface 26sh and the rectangular notch 27sn of the lower guide plate 27, and the front wall 2fw thereof
The front wall 2f has a flat T-shaped plunger 28 integrally formed with an overhang portion 28b having a width equal to the width of the upper guide plate 26 and the lower guide plate 27 at the distal end farther from the inner surface of the front wall 2f.
It is inserted so as to be able to advance and retreat in a direction orthogonal to w. Two pairs of bolts 29 are provided on both end surfaces in the width direction (width direction of the upper guide plate 26 and the lower guide plate) of the projecting portion 28b of the plunger 28 and on the width direction outer surfaces of the pair of spacer plates 29.
The two ends of a pair of tension coil springs 28cs are locked to the two pairs of bolts 29b along the outer surfaces of the pair of spacer plates 29, respectively. Is constantly biased toward the front wall 2fw.

A push rod PR shown in FIG. 10 is attached to the front door 2fw of the plunger 28 of the cord pull-out brake mechanism 25 when the main door 9 is closed.
The plunger 28 is connected in such a manner as to come into contact with the end face on the side and to push the plunger 28 in a direction away from the front wall 2fw by overcoming the urging force of the pair of tension coil springs 28cs (right side of the paper surface in FIGS. 9 and 10).

FIG. 9 shows that the main door 9 is opened, the push rod PR is retracted from the position in contact with the end face on the front wall 2fw side of the plunger 28, and the plunger 28 is extended by the urging force of the tension coil spring 28cs. The side face on the front wall 2fw side of the front wall 2b is the front wall 2 of the pair of spacer plates 29.
It shows a state in which it has been pushed back to the “half brake position” where it comes into contact with the end face farther than fw. In this state,
The end face of the rectangular through hole 26sh of the upper guide plate 26 and the square notch 27sn of the lower guide plate 27 that are farther from the front wall 2fw and the end face of the plunger 28 that is closer to the front wall 2fw of the rectangular through hole 28sh. The vertical distance d is formed so as to be smaller than the diameter Ds of the string 12 (for example, dｓDs / 2), and the string 12 is formed by the end face of the rectangular through hole 28sh of the plunger 28 on the side close to the front wall 2fw. 2f
It is bent and detoured in a direction away from w (right side in FIG. 9) and is in a somewhat crushed state. As a result, not only the downward pulling force of the portion of the string 12 below the string pulling out brake mechanism 25 due to its own weight but also the manual pulling force, the constant resistance ( For example, about 5 kg), the resistance becomes a weak braking force, and natural pulling out of the string 12 by its own weight is prevented. Also, the string is pulled down manually only during the time when the string is applied with a tensile force of a predetermined strength or more that overcomes the above-described resistance, and the string is excessively pulled by the inertia force because the tensile force is too strong. There is no withdrawal.

When the main door 9 is closed, the push rod PR connected thereto comes into contact with the end face on the front wall 2fw side of the plunger 28, and overcomes the bias of the tension coil spring 28cs to separate the plunger 28 from the front wall 2fw. Pushing the plunger 28 in the direction (the right side in FIGS. 9 and 10) brings the plunger 28 into the "brake position" shown in FIG. In this state, the binding string 12 bends rightward in FIG. 10 at the lower end edge of the inner surface of the upper guide plate 26 on the side farther than the front wall 2fw of the rectangular through hole 26sh, and the upper guide plate 26
The gap between the lower surface of the plunger 28 and the upper surface of the plunger 28 is crushed, and the front wall 2f of the square notch 28sn of the plunger 28
It bends downward along the inner surface on the w side, and bends at the lower end of this inner surface in the leftward direction in FIG.
The front wall 2f of the rectangular notch 27sn of the lower guide plate 27 passes through the gap between the upper surface of the
It bends downward at the upper end edge of the inner end surface farther than w and is guided to the front string guide means 52 of the press plate 11 described above. In this manner, in a state where the plunger 28 is located at the “brake position” shown in FIG. 10, even if the binding string 12 is to be pulled downward, the binding string 12 is moved to the upper guide plate 26 of the string extraction brake mechanism 25. And between the lower surface of the plunger 28 and the upper surface of the lower guide plate 27, and is bypassed in a crushed state. ,
For example, when about 110 kg, the strength of this resistance is
For example, it is about 30 kg), and the strong resistance works as a brake, and the string is not pulled down.

Since the string pulling out brake mechanism 25 according to the fourth embodiment of the present invention is constructed as described above, the following excellent operational effects can be obtained. (1) When the string 12 is guided and set along the same route as above with the main door 9 opened, the string pull-out brake mechanism 25 is in the "half-brake position", and the string 12 is constantly tightened. It can be pulled out little by little, and the string becomes slack, unlike the conventional string pulling brake mechanism, and there is no need for any extra work such as rewinding the reel 13 in reverse to remove the slack. (2) When the main door 9 is closed to compress the workpiece D, the string draw brake mechanism 25 is switched to the “brake position”, and as with the conventional string draw brake mechanism, the press plate 11 is lowered. The string is not pulled out and slackened, so that defective packing can be prevented.

Next, the eject mechanism 20 according to the fifth embodiment of the present invention will be described. FIG.
FIGS. 12A and 12B and FIGS. 12A and 12B are diagrams showing the configuration of the eject mechanism 20 and its operation. The eject mechanism 20 is disposed on the bottom wall 7 of the compression chamber 4 and has a front end portion rotatably supported by the bottom wall 7 via a rotation shaft 21a.

Next, the eject hook mechanism 31 according to the fifth embodiment of the present invention will be described.
As shown in detail in FIGS. 4 and 5, the eject hook mechanism 31 has a hook portion 33a at the tip, and the tip of the cam follower 60 of the block interlocking portion 57 is inserted into the middle portion and linked. Connecting groove 33b
(See FIG. 5), a coil spring 34 that constantly urges the entire slide member 33 toward the rear wall 6, and a slide of the slide member 33 associated with the inner surface of the main door 9. And the like. The link mechanism 35 includes a rotating plate 37 rotatably attached to the press plate 11 via a pivot 36.
And a slide rod 39 that is linked to one end of the rotating plate 37 via a shaft 38. The other end of the rotation plate 37 is linked to the slide member 33 via a pivot 40. Also, slide rod 3
Numeral 9 extends in the front-rear direction and is slidably mounted in the front-rear direction via a guide mechanism 51. The front end 39a projects to the front side of the press plate 11 so as to be able to contact the inner surface of the main door 9. Has become.

When the main door 9 is open, the resilient force of the compression coil spring 34 causes the entire slide member 33 to move toward the rear wall 6 so that the eject hook mechanism 31 configured as described above Is an "interlocking position" at which it can be engaged with the pulling rod 32 of the operating member 23. The dashed line in FIGS. 4 and 5 indicates a solid line and a broken line in FIGS. 11B, 12A and 12B. It protrudes to the position 示 す shown by. Further, the rod 58 interlocking with the slide member 33 rotates together with the cam follower 60 and the operating arm 59 in the clockwise direction in FIG.

5 is rotated clockwise to the position indicated by the two-dot chain line in FIG. 5, the slide rod 39 slides forward, and the front end 39 a is projected more than the front side of the press plate 11.

When the main door 9 is closed in this state, the slide rod 39 is pushed against the rear wall 6 against the urging force of the compression coil spring 34 with the closing operation of the main door 9. Then
Rotating plate 37 in conjunction with movement of slide rod 39
Is returned in the counterclockwise direction in FIG. 4 to the position shown by the solid line in the figure, and at the same time, the slide member 33 is moved to the position shown in FIGS.
The position is returned to the “non-interlocking position” indicated by the solid line in FIG.
In this “non-interlocking position”, the entire slide member 33 is released into the press plate 11 to a position where the hook portion 33 a does not engage with the lifting rod 32 of the link 23. On the other hand, the rod 58 linked with the slide member 33 also
The block member 55 moves to the “block position” by rotating together with the cam follower 60 and the operating arm 59 in the counterclockwise direction in FIG. Then, when the main door 9 is opened again, the eject hook mechanism 31 returns to the “interlocking position” by the repulsive force of the compression coil spring 34, and the block member 55 moves to the “unblocking position”.

As shown in FIGS. 11 and 12, the guide frame 24 has an upper end 24t which is bent in a V-shape to the rear wall 6 side. With the main door 9 opened as described above and the eject hook mechanism 31 in the "interlocked position", the hydraulic cylinder 10 is operated to raise the press plate 11 at the lowered position shown in FIG. On the way, the hook portion 33a engages with the lifting rod 32 of the link 23, and the upper end of the link 23
Is lifted upward together with the press plate 11 ascending while being guided by the front surface of. As the link 23 rises, the rear end of the tilting bottom plate member 21 connected to the lower end of the link 23 via the rotating shaft 22 is lifted upward and gradually tilts. The compressed / packaged workpiece D on the bottom plate member 21 rolls or slides, and is forcibly discharged from inside the compression chamber 4 to the outside. Further, the upper end of the raised link 23 gradually moves toward the rear wall 6 along the front surface of the upper end 24t that is bent in the shape of a letter C on the rear wall 6 side of the guide frame 24,
At a predetermined raised position, the engagement between the lifting rod 32 at the upper end of the link 23 and the hook 33a of the eject hook mechanism 31 is released, and the link 23 and the tilting bottom plate member 21 are lowered to their initial positions by their own weight. At this time, the above-mentioned damper (hydraulic damper or gas damper) 62 operates, and the link 23 and the tilting bottom plate member 21 return to the initial position gently. Breakage of the tilting bottom plate member 21 is prevented.

FIGS. 13 to 16 are views showing the state of each step of the operation of the compression packing apparatus in the present embodiment according to claims 2 to 5. Hereinafter, a compression and packing operation using the compression and packing apparatus of the present invention will be described with reference to FIGS. 13 to 1
In order to make the explanation easy to understand in FIG. 6, it is displayed and explained as follows. (1) The string pull-out brake mechanism 25 is in a state where the plunger 28 is located at the “semi-brake position” and can pull out the string 12 only while a pulling force of a predetermined strength or more is applied. Plunger 2 indicated by “□”
The state in which the string 8 is located at the “brake position” and the string 12 cannot be pulled down is indicated by a mark “■”. (2) The slide member 33 is displayed as a type that rotates for convenience, and the rotation causes the hook portion 33a to rotate.
1 from the rear end side to the rear wall 6 side, or press plate 11
A description will be given of a case where the user retracts inside. (3) The rear end string guide means 53 changes the state of the “latch position” where the block member 55 is disposed at the “block position” so that the binding string 12 cannot be inserted into or removed from the string through hole 45. ● ”, the block member 55
Is indicated by the mark “○” in the “unlatched position” where the “B” is arranged at the “unblock position” and the binding string 12 can be inserted into and removed from the string passing hole 45.

The compression / packing operation is performed in step ST1 of FIG.
To step ST12 in FIG. 16, and the operation will be described in order. First, when the compression packing device 1 is not used, step ST1
As shown in the figure, the main door 9 and the auxiliary door 9b are closed. The binding string 12 is guided and set along the above route. When the upper door 9b is closed, the string pulling brake mechanism 25 is switched to the “brake position”, and the hook portion 33 of the slide member 33 is moved.
“a” has retracted to the “non-interlocking position” in the press plate 11. At the same time, the block member 55 is located at the "block position", and the rear string guide means 53 is at the "latch position". The press plate 11 is moved above the compression chamber 4 by the hydraulic cylinder 10.

Next, when the compression packing device 1 is used,
Only the auxiliary door 9b is opened, and an object to be processed such as paper waste is loaded into the compression chamber 4 (step ST2). When the loading is completed, the auxiliary door 9b is closed (step ST3). After a while
The hydraulic cylinder 10 is driven by operating a start switch (not shown) provided on the press plate lifting drive unit 3, and the press plate 11
Descend. Then, the workpiece D is gradually compressed as the compression press plate 11 descends. When the press plate 11 descends to a predetermined height, it is automatically stopped by a limit switch (not shown). Also, during this time,
The string pulling brake mechanism 25 is switched to the “brake position”, so that the binding string 12 is not pulled down and pulled out of the reel 13 by the lowering of the press plate 11, and the rear string guiding means 53 also a block member 5
5 remains at the "block position", the "latch position" is maintained, and the binding string 12 does not come off the rear string guide means 53 (step ST).
4).

When the press plate 11 descends to a predetermined height and stops, the main door 9 is opened. Then, the string pull-out brake mechanism 25 is switched to the “semi-brake position”, the hook portion 33a of the slide member 33 projects outside the press plate 11 to the “interlocking position”, and the block member 5 is moved.
5 moves to the "unblock position", and the rear string guide means 53 is also switched to the "unlatch position" (step ST5). Subsequently, the operator operates the lifting start switch of the press plate 11. Then, driven by the hydraulic cylinder 10, the press plate 11 is raised to a raised position before the hook 33 a of the slide member 33 comes into contact with the lifting rod 32. As the press plate 11 rises, the string 12 is pulled downward by the load of the compressed workpiece D, and is automatically released from the rear string guide 53 and is lower than the front string guide 52. The string 12 hangs down (step ST6). The operator pulls the hanging string 12 out of the front side of the compression chamber 4, and cuts the string at an appropriate position (step ST7). One end of the cut string 12 is connected to the other end of the string locked by the string tip locking portion 21f (see FIG. 1) at the front end of the tilting bottom plate member 21 (step ST8). Thus, the packing of the compressed object D is completed.

When the packing of the workpiece D is completed, as a part of preparation for the next work, the tip of the binding cord 12 on the reel 13 side is tied round, and this is attached to the main door 9 by a hook (not shown). And the tip is lifted together with the press plate 11 so as not to escape (step ST9).

Subsequently, when the start switch is operated again,
The hydraulic cylinder 10 is driven to raise the press plate 11 again, and on the way, the hook portion 33a of the slide member 33 engages with the lower side of the lifting rod 32, and continues to rise while lifting this. When the lifting rod 32 is lifted, the link 2 to which the lifting rod 32 is attached is connected.
3 is also lifted together with its upper end being guided by the front surface of the guide frame 24, and the rear end of the tilting bottom plate member 21 connected to the lower end of the link 23 by the rotating shaft 22 is also raised at the same time. With the rise of the link 23, the tilting bottom plate member 21 largely tilts toward the opening 8 side, and when this tilt exceeds a certain limit, the compression /
The packaged workpiece D rolls or slides, and the compression chamber 4

1).

Further, when the press plate 11 is further raised to a predetermined position, the upper end of the link 23 is bent at the upper end 24t of the guide frame 24 shown in FIGS. It is guided to the front and gradually rises while moving to the rear wall 6 side.
The engagement between the lifting rod 32 at the upper end of the hook 3 and the hook portion 33a is released, and the link 23 and the tilting bottom plate member 21 are lowered to the initial position. At this time, the link 23 and the tilting bottom plate member 21 are provided with a damper (a hydraulic damper or a gas damper) 62.
Works and slowly returns to the initial position. On the other hand, the workpiece D discharged from the compression chamber 4 is then placed on a conveyor belt or the like, transported to another position, and processed. When the press plate 11 further rises to a predetermined position and the limit switch is operated, the hydraulic cylinder 10 stops, and the press plate 11 also stops at that position. After stopping, the worker guides and sets the string 12 along the route while pulling down the binding string 12 (step ST12).

To process the next object to be processed again, the main door 9 is closed and only the auxiliary door 9b is opened. Then, by repeating the operation from step ST2 to step ST12, the compression / packing process can be performed continuously.

The compression packing device of the present invention is not limited to the above-described embodiment. For example, the string through hole forming member 43 constituting the rear side string guide means 53 can be used.
And the shape and structure of the block interlocking portion 57 can be appropriately changed as necessary.

Further, switching between the "block position" and the "unblock position" of the block member 83 in the embodiment of the present invention according to claim 1 and the block in the embodiment of the present invention according to claim 2 Switching between the “block position” and the “unblock position” of the member 55 is performed by the main door 9.
Disclosed the structure that switches in conjunction with the opening and closing of the, but other than that, for example, the worker can directly switch by hand,
Alternatively, the actuator may be switched by another actuator (a hydraulic cylinder, an electric motor, a feed screw mechanism, or the like) in conjunction with a start switch that controls the hydraulic cylinder 10.

Further, the numbers of the reels 13, the cord pull-out brake mechanism 25, the front cord guide means 52 or 85 and the rear cord guide means 53 or 84 are not limited to three sets, but may be appropriately determined according to the width of the compression packing device 1. Just choose
If the width is narrow, two sets may be used; conversely, if the width is wide, 4 sets
More than a pair may be used.

Further, for driving the press plate 11 up and down,
Instead of the hydraulic cylinder 10, an electric motor and a feed screw mechanism may be used.

The reel 13 is used as the string supply means. Instead, a coil wound in a coil shape is placed in a fall prevention box with the winding axis set vertically, and the coil is wound. You may make it pull out a string from inside.

As described above, the present invention has the following excellent effects. (1) According to the first aspect of the present invention, when performing a compressing operation, when the press plate repeatedly descends and ascends, the rear string guide means securely holds the binding string so as not to be removed. Therefore, it is possible to reliably prevent the binding cord from coming loose during the compression process and causing loose packing. As a result, the reliability in the packing operation can be improved. This does not change even if the speed of lowering the press plate in the press operation is increased, so that the operation speed can be improved.

(2) According to the second aspect of the present invention, in addition to exhibiting the same effects as in the above item (1), when guiding and setting the binding string prior to the introduction of the object to be processed, When the cord is locked to the locking part on the rear end side of the press plate, no complicated operation using both hands is required, and the press plate is raised when packing the workpiece after compression. By simply doing so, the string can be naturally released from the locking portion on the rear end side by the weight of the object to be processed, or at least the string can be detached from the locking portion on the rear end side by simply pulling the string lightly by hand. . This makes it possible to simplify the working process by minimizing the complicated operation by hand as much as possible, without requiring any skill in the work, and when the strap for binding is pressed after the press plate during the work of compressing the object to be processed. It is possible to improve the reliability and speed of the work by preventing the package from being detached from the locking portion on the end side and causing defective packing.

(3) According to the third aspect of the present invention, an interlocking mechanism is provided between the main door of the compression chamber and the block member of the rear string guide means, and when the door is closed, the block member is moved. Since it is automatically moved to the block position, when the unskilled worker forgets to operate the mechanism for preventing the string from coming off from the rear string guide means by the block member, and performs the compression work, It is possible to prevent the string from being detached from the guide means and causing a defective packing, so that no skill is required for the work. Further, it is possible to further improve the reliability and speed of the packing process.

(4) According to the fourth aspect of the present invention, the work of guiding and setting the binding strap to a predetermined route prior to the loading of the object to be processed can be performed while always tightening the binding strap. It can be wound on a reel or wound in a coil shape by the inertia force due to the excessive force of the worker pulling the binding strap downward, or by the weight of the binding strap hanging down, and the winding shaft is The bundling cord placed vertically is not pulled out excessively and becomes slack, and does not require extra rewinding work to remove the slack. The process can be simplified and work efficiency can be improved.

(5) According to the fifth aspect of the present invention, after the object to be compressed and packed is discharged from the compression chamber by the tilting of the tilting bottom plate member, the tilting bottom plate member and the tilting mechanism descend. In addition, it is possible to gently move down by the action of the damper, and it is possible to prevent generation of a loud impact sound due to collision with the bottom wall of the compression chamber and damage to the tilting bottom plate member and the tilting mechanism.
