Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veil forming machine for forming waste paper, sponge, nylon, Styrofoam, etc. on a veil.

[0002]

2. Description of the Related Art Waste paper, sponge, nylon, Styrofoam, etc. are collected and stored in a predetermined storage place or transferred to a predetermined treatment place. However, there is a problem in that the transport efficiency is extremely low because the volume is considerably small compared to the volume.

Therefore, recently, attempts have been made to solve the above problems by compressing these to form a lump of a predetermined size.

FIG. 17 and FIG. 18 concretely show the structure of a bale forming machine which has already been developed for forming this type of object to be processed into a bale of a predetermined size.

This bale forming machine A is mainly composed of a machine frame 101 which is a housing, and a rear carrier 102 and a front carrier 103 which are arranged in the machine frame 101 and constitute one compression means.
And a compression chamber 104 for the object to be processed, which is partitioned by a partition wall that surrounds the front carrier 103 and the rear carrier 102.
A string feeding device (not shown) for supplying a string or the like to be wound around the outer periphery of the bale 105 (see FIG. 19) formed in the compression chamber 104, and the rear carrier 102 and the front carrier 103. It is composed of a driving device 106 for driving.

More specifically, the rear carrier 102, which constitutes one of the compression means, includes the left and right side plates 107, 107 of the machine casing 101.
A first roller 1 which is rotatably supported about a horizontal axis.
08, the second roller 109, the third roller 110, and the oscillating plate 111 rotatably supported on the left and right side plates 107, 107 about the horizontal axis so as to be rotatable about the horizontal axis. A front part transporter that is composed of a fourth roller 112 that is axially supported and a first endless belt 113 that is endlessly wound around these first to fourth rollers 108, 109, 110, 112, and that constitutes the other of the compression means. The body 103 has a fifth roller 117 and a sixth roller 117, which are rotatably supported on the left and right side walls 114 of an integral rotary frame 116 formed by connecting the left and right side walls 114 with a back wall 115, respectively. Roller 11
8th and 7th roller 119, 8th roller 120 movably supported on the left and right side walls 114 thereof in the vertical direction, and 6th roller 118, 7th roller 119, 8th roller 1
Second endless belt 12 endlessly wrapped around 20
The first to fourth rollers 108,
109, 110, 112 are arranged in a substantially L shape, and the sixth roller 118, the seventh roller 119, and the eighth roller 120 are arranged in a substantially inverted shape, and the upper shaft support portion of the rotating frame 116 is
At the position when the rotating frame 116 is rotated downward by a predetermined angle, the rear belt portion of the second endless belt 121 faces the front belt portion of the first endless belt 113, The left and right side plates 107, 107 are pivotally supported from the middle to the lower side.

Therefore, for the formation of the bale, the compression chamber 10
4 is divided, the rotation direction of the rotation frame 116 is as shown in FIG.
As shown in FIG. 9C, when the bail is taken out from the compression chamber 104, the rotating frame 116 rotates in the opposite counterclockwise direction as shown in FIG. 19B. FIG. 19A shows a state in which the rotating frame 116 is closed.

Next, the rear carrier 102 and the front carrier 1
The drive device 106 that drives the motor 03 to form the bale will be described. As shown in FIG. 18, the motor 122, which is the drive source, drives the first endless belt 1 from the rear wall 123 of the machine frame 101.
The first sprocket 125 is fixed to the output shaft 122a of the motor 122 so as to transmit the rotational force of the motor 122. The first sprocket 125 is fixed to the output plate 122a of the motor 122. On the other hand, a second sprocket 126 and a first spur gear 127 are attached to a support shaft 116a of the rotating frame 116, and a third sprocket 128 is pivotally supported on a lower portion of the side plate 107 of the machine frame 101. There is. Then, as shown in FIG.
The second spur gear 129 and the fourth sprocket 130 are fixed to the support shaft 118a that pivotally supports the roller 118 by meshing with the first spur gear 127, and as shown in FIG. 18, the support shaft 117a of the fifth roller 117 is supported. The fifth sprocket 131
Is fixed.

A sixth sprocket 132 is fixed to the first roller 108.

The first sprocket 125, the second sprocket 126, the third sprocket 128, and the sixth sprocket 132 are endlessly attached to the first chain 133.
The second chain 134 is endlessly wound around the fourth sprocket 130 and the fifth sprocket 131. Further, a first spring 135 is stretched between the swing plate 111 and the side plate 107 of the machine frame 101 in order to apply tension to the first endless belt 113, and the fourth roller 11 is stretched.
2 is urged counterclockwise in FIG. 14, and the support shaft 120a of the eighth roller 120 and the side wall 1 of the rotating frame 116 are
A second spring 136 is stretched between 14 so as to urge the eighth roller 120 downward in FIG. 17 so as to apply tension to the second endless belt 121.

Therefore, when the motor 122 is rotated counterclockwise in FIG. 18, the first chain 133 rotates counterclockwise in the second chain 134, the first and second endless belts 11.
3,121 will be rotated clockwise.

Therefore, as shown in FIG. 19B, the waste paper or the like put into the compression chamber 104 has a belt tension of each of the first endless belt 113 and the second endless belt 121 whose traveling directions are opposite to each other. Is pressed and compressed while being rotated to form a cylindrical bail 105.

Here, the first and second endless belts 113, 1
The compression force of 21 is mainly a component force corresponding to the angle (wrapping angle) of the belt wrapped around the object to be compressed. In FIG. 17, reference numeral 137 is an input port, 138 is a table, and 139 is a door.

[0014]

However, the above-mentioned bale forming machine has the following problems.

In the bale forming machine, the tensions of the first spring and the second spring are set, and the tensions of the first endless belt and the second endless belt are set by the arrangement of the rollers forming the rear conveyance body and the front conveyance body. In this way, the object to be compressed is compressed and rotated to form a cylindrical bale.
Of the belt tension, the endless belt and the second endless belt act only as a compressive force on the object to be compressed due to the angle wrapped around the object to be compressed, and the component force can also be added to the belt due to the physical properties of the belt. Since there is a limit to the tension, there is a problem that a high packing pressure cannot be applied to the object to be compressed and therefore the compression efficiency is poor.

This problem is particularly noticeable when a bulky box or the like is compressed and packed.

Further, since a considerable amount of tension must be applied to the first endless belt forming the rear conveyance body, there is a corner on the object to be compressed, or the object to be compressed is hard. If the substance is mixed, the belt surface is easily damaged, and if it is damaged, the belt will be broken due to the large number of belt bendings at the roller. There is a problem.

When the surface of the endless belt is formed in a concavo-convex shape in order to increase the conveying ability, stress when the belt is bent is concentrated in the concave portion, which also increases the frequency of breakage of the belt.

Further, in the initial stage of the bale formation, the flat belt, which is provided with sufficient tension in the compression chamber having an inverted V-shape with an acute angle, is expanded to push the object to be compressed into the compression chamber and automatically rotate into a cylindrical shape. Configuring to be formed is
Considering the tension applied to the belt, it is quite difficult to do so.Before starting the work, the object to be compressed is rounded to a predetermined size in advance, and this is used as the core for bale formation and is first charged into the compression chamber to form nuclei. After that, the compression work had to be performed, and there was a problem that the work was difficult to proceed.

An object of the present invention is to provide a bale forming machine configured to form a compressed object such as waste paper, sponge, nylon, styrofoam, etc. into a veil having a predetermined volume without using an endless belt. It is in.

[0021]

In order to achieve the above object, the present invention provides a bale forming machine for forming an object to be compressed, such as waste paper, sponge, nylon, Styrofoam, etc., into a bale having a predetermined volume. , A housing surrounding the rollers, a loading port for loading the object to be compressed into a cylindrical space defined inside the rollers, and the rollers rotating in the same direction. And a roller driving device for rotating the compressed material supplied into the space to form a bale.

[0022]

[Function] The object to be compressed such as waste paper, sponge, nylon, Styrofoam, etc., which has been dropped from the input port, is supplied into the cylindrical space and receives the compressive force by the rollers rotating in the same direction, so that it is moved in the same direction as a whole. It turns into a cylinder. Therefore, if the object to be compressed is sequentially charged into the space, the object to be compressed is expanded in diameter, and if a predetermined amount of the object to be compressed is charged, the bale has a constant volume.

Next, the roller 15 forming the compression chamber 16
, 23 and a drive device for the scraping rotor 17 will be described.

As shown in FIGS. 4 and 13, the motor 60 with a speed reducer, which is a drive source, is located above the scraping rotor 17 and is fixed to a motor support plate 61 which is horizontally stretched between the side plates 2 and 3.

It is driven by the passed fourth chain 71. Here, the axis 27 of the smoothing roller 23 on the upper part of the rotating frame 14 and the axis of the pivot shaft 24 of the rotating frame 14 are eccentric. Since the corresponding rotation locus of the shaft center 27 of the smoothing roller 23 and the arc of the shaft center 27 of the smoothing roller 23 having the scraping rotor 17 as the shaft center are similar, even if the rotating frame 14 is expanded upward. There is no hindrance to the rotational drive of the roller 15. The driving of the roller 15 in the other rotating frame 14 is the same as the driving of the roller 15 between the side plates 11 and 12.

The binding device 18 is located at the rear of the machine frame 1,
Upper two rollers 15 supported between the side plates 11 and 12
A certain amount of string is fed between the bail 22 and the roller 15
The cord feeding section 79 to be sandwiched between the cords, the carrier 81 for supporting and conveying the cord to spirally wind the cord around the bail 22, the guide 82 and the screw 83, and the cord cutting device 84 after the winding. And a drive device (not shown) having an electromagnetic clutch and a string storage box 85. A discharge port 76 for the veil 22 is formed in the lower front portion of the machine frame 1 and is covered with a front cover 77. Further, an arm 78 is rotatably supported on the lower portion of the machine frame 1 to stop rolling of the discharged bale 22.

Next, the operation will be described.

When an object to be compressed, such as a box made of paper, vinyl, or cardboard, is put into the charging port 6, the object to be compressed is scraped into the rotor 1.
7, a number of rollers 15 and folds which are compressed and creased, and projecting ridges 15a are provided on the circumference thereof, and smooth rollers 2
It is scraped into the compression chamber 16 which forms a cylindrical space in 3.

Here, the object to be compressed, which is creased and easily bent, is a veil 22 with a wide flat belt as in the conventional case.
The core bale 22 at the initial stage of formation is not required, as in the case of forming, and is fed in the direction of rotation of the roller 15 provided with the protruding body 15a and rolled to form the cylindrical bale 22.

Further, the object to be compressed is charged and the rotor 1 is scraped.
7 makes a crease and forcibly scrapes it to increase the diameter of the bale, and when the outer periphery of the bail 22 comes into full contact with the rollers 15 and 23, the protrusion 15 of the roller 15
Due to a, a cylindrical bale 22 is formed which has a large packing pressure and a large compression rate. Further, the smoothing roller 23 at the upper end in the rotating frame 14 prevents scraping of the compressed object in the rotating direction of the roller 23. Roller 15,
23, the scraping rotor 17 and the left and right compression chamber side plates 11,
12, the rotating frame 14, and the table 25 are hard materials (in this embodiment, stainless steel, but the rollers 15, 23 may be made of non-ferrous materials such as ceramics). Even if a hard substance such as glass fragments or plastic is mixed, the frequency of damage is low and efficient work can be performed.

As shown in FIG. 15, the rotating frame 14 is adapted to rotate and open / close around the pivot shaft 24 in association with the expansion and contraction of the electric cylinder 30, and at the initial stage of formation of the bail 22, It is closed by the biasing force of the spring 52. When the packing pressure increases as the bale 22 in the compression chamber 16 grows, the rotating frame 14 is expanded as shown in FIG. 3 against the biasing force of the spring 52. That is, since the electric cylinder 30 does not expand or contract except during operation, the counterclockwise rotation of the rotating frame 14 causes the timepiece with the connection point 54 between the stay 39 and the short arm 44 of the second connection arm 45 as a fulcrum. A turning force is generated at the long-side arm connecting point 55, and the connecting body 50 is pulled up against the biasing force of the spring 52.

The detector 53 detects the movement of the long arm 43 and issues a warning sound to give a warning. Further, the packing pressure can be adjusted by changing the tightening amount of the spring 52.

When the tying device 18 is turned on based on the warning, a tying motor (not shown) is actuated, and a certain amount of the cord is fed out between the two upper rollers 15 to make the roller 15
And the outer periphery of the bale 22 are sandwiched and wound. At this time, the cord is spirally wound around the bail 22 by feeding the cord to the left and right, and the cord is cut by the cutting device 84 after being wound by the required length.

When the electric cylinder 30 is actuated and extended after the cord is cut off, the rotary frame 14 is rotated counterclockwise and pulled up to open the compression chamber 16 and the bale 22 is discharged by its own weight and the rotation of the roller 15. To be done. Gas spring 3 at this time
The urging force of 1 acts as an aid for pulling up the rotating frame 14.

Further, the smoothing roller 23 positioned near the inside of the pivotal support shaft 24 in the rotary frame 14 is located at a position beyond the semi-circle of the lowermost roller 15 among the rollers 15 supported between the side plates 11 and 12. Therefore, the veil is sandwiched even after the veil 22 is formed. However, since the smoothing roller 23 is eccentric to the front side of the axis of the pivot shaft 24, when the rotating frame 14 is expanded upward, the space between the lowermost roller 15 and the smoothing roller 23 expands and the bale 22 is discharged without being supported. To be done.

As described above, according to the bale forming machine B, it is possible to eliminate the conventional problem of forming the core material before the start of the bale formation, and to form a bale having a high volume reduction rate. be able to.

However, as a result of further examination of the bale forming machine B, in the case where the object to be compressed is cut into an appropriate size in advance before forming the bale and is supplied to the compression chamber 16 to form the bale 22. Compared with the case where the bale 22 is formed by directly supplying the compressed object to the compression chamber 16 without any modification, in the former case, there is no protrusion protruding from the surface, and there is no gap in the whole. However, in the latter case, the part bent by the scraping rotor 17 pops out from the surface of the bale, and the bent part overlaps with each other to form a large void (gap) in the veil. I understood it. For example, when a corrugated cardboard is used as a veil, the bending does not result in bending along the axial direction of the scraping rotor 17 due to the strength of the waist, and a portion where the bending does not work well protrudes to form a void in the veil. Like In addition, for containers with corners that are difficult to compress and styrofoam containers for food packaging that are elastic and difficult to compress, the occurrence rate of voids is considerably large, and it is easy to misload and cannot be transported. There's a problem.

Therefore, if the object to be compressed can be cut into a predetermined size before it is scraped into the compression chamber 16, such a problem can be solved.

Another embodiment of the bale forming machine according to the present invention will be described below. Note that basically the same configurations as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

03 is fixed to the cutting rotor 302, and a fixed blade 305 having a rectangular cross section is fixed to the tip of the table 25 in parallel with the axial direction of the rotor shaft 304.

As shown in FIG. 7, the cutting rotor 302 is arranged above the connecting portion 6a communicating with the compression chamber 16 and is rotatably supported between both side plates 2 and 3 in the machine frame 1. . In addition, the cutting edge 303 has an edge 303a slightly separated from an edge 305a of the fixed blade 305 in order to reduce resistance at the time of cutting, and is oblique to the axial direction of the rotor shaft 304 so as to be oblique to this. It is fixed to the eyes.

An actuator (an electric cylinder in this embodiment) 30, which is an opening / closing device 19 for the rotary frame 14, is arranged in the upper portion of the machine frame 1, and the connecting arm 37 and the machine frame 1 are provided.
It is connected to both side surfaces of the rotary frame 14 via stays 39 on the outer side plates 2 and 3.

That is, when the actuator 30 is extended, the rotary frame 14 rotates counterclockwise to open the compression chamber 16, and when the actuator 30 is retracted, the rotary frame 14 rotates clockwise. As a result, the compression chamber 16 is closed.

The bundling device 18 is rotatably supported by a lower roller 80 which is rotatably supported by a support plate 88 which is erected and fixed at a substantially intermediate portion between the side plates 11 and 12, and is biased toward the lower roller 80.

In summary, according to the present invention, the following excellent effects are exhibited.

(1) It is possible to form a bale having a high packing pressure and a high compression rate.

(2) Since the object to be compressed scraped into the compression chamber is sent in the direction of rotation by the rollers and rolled to form a columnar shape, it is possible to perform compression work using a conventional endless belt (flat belt). Thus, the operator can be relieved from the burden of the preceding work of rolling the object to be compressed each time in the initial stage of roll formation.

(3) By the scraping rotor, it is possible to compress the object to be compressed, make a crease, and scrape it into the compression chamber, so that it is possible to surely form the cylindrical bale. Further, the bale having a large packing pressure and a large compression rate can be formed by the forced scraping and the compression of the rotor.

(4) A cutting device is provided in front of the inlet of the compression chamber of the bale forming machine for forming a cylindrical bale, and the object to be compressed is cut into an appropriate shape and supplied to the compression chamber. The objects are pressed against each other without a gap, so that a good bale of the object to be compressed having a high density and no variation in the density can be obtained. That is, since a veil having a higher volume reduction rate than that of the conventional one can be obtained, the transport efficiency of the formed veil can be improved, and the storage space of the formed veil can be reduced, and a great economic effect can be expected.

(5) Since a large number of rollers and the scraping rotor are made of hard materials, they can handle a large packing pressure,
Further, foreign matter such as hard matter mixed in the object to be compressed is less likely to be damaged, and efficient work can be performed.
