[Detailed description of the invention]

(Industrial Application Field) The present invention relates to an apparatus for forming and filling bags and for charging filled bags into cardboard boxes. (Prior Art) Conventionally, this type of device is disclosed in, for example, US Pat. No. 3,983,682. The apparatus disclosed herein deals with forming and filling bags and loading the bags filled with a specific substance into a cardboard box, and in order to facilitate the guidance of the filled bags into the cardboard box. , a guide means consisting of a pair of opposed channel members is used to accommodate a filled bag suspended therein by vibrating the guide members.
The guide means (corresponding to the forming means of the present invention) enters into the opening of the carton box, loads the filled bag into the carton box, and then moves the filled carton box from the charging position. Rising from inside the cardboard box. (Problems to be Solved by the Invention) However, conventional devices using such guide means have the following problems. First, since the guide means moves in and out of the ball, the operating speed of the device is slow, resulting in low productivity. Second, when a suspended filled bag is separated and falls, its descending speed is reduced due to frictional contact with the guide means and the cushioning effect of the air inside the box, causing the inside of the box to drop. The bag is prevented from falling at high speed. Therefore, the present invention aims to solve the above problems. SUMMARY OF THE INVENTION The present invention includes a hollow mandrel for laterally sealing a flexible sheet material to form a tube; A sealing/cutting means is provided to form a bag and to separate the bags individually from the tube and drop them, and a long passage is formed vertically below the sealing/cutting means so that the filled bag filled with the product can be removed by the sealing/cutting means. forming means substantially conforming to the internal cross-sectional area of the receiving box to be charged; and positioning below the forming means for moving the receiving box into a position in line with the mandrel for the receiving box to receive falling filled bags; a bag comprising conveyor means and means for positioning the bins one at a time below the forming means to receive the filled bags and then driving the conveyor means to move the loaded bins; Concerning forming, filling and post-filling carton box charging equipment. In order to solve the first problem, the present invention provides the forming means with a gap formed between the lower end of the forming means and an opening of a storage box located at a receiving position, and a space provided within the forming means. The filled bag was fixed at a position where a gap was formed between the lower end of the filled bag and the opening of the storage box (hereinafter referred to as the first invention). In addition to the configuration of the first invention that solves the first problem, the present invention also provides an air flow directed downward from the sides of the bag into the forming means in order to solve the second problem. A means for blowing down was provided (hereinafter referred to as the second
invention). Furthermore, in addition to the configuration of the second invention that solves the first and second problems, the present invention provides a structure in which the molding means is vibrated and suspended in order to more effectively solve the second problem. Vibration means were provided to adapt the filled bag to the cross-sectional area of the forming means (hereinafter referred to as the third invention). Furthermore, in addition to the structure of the first invention that solves the first problem, the present invention provides a method for solving the second problem by providing a method for forming a molding device which is positioned at the lower end of the forming means and inside the open end of the storage box. It is capable of being lowered and is provided with means for deflecting and holding the closing member at the top of the storage box outward (hereinafter referred to as the fourth invention). (Operation) The first invention operates as follows. The flexible sheet material is laterally sealed with a mandrel to form a tube. The tube is then laterally sealed by a sealing and cutting means. The product is supplied to the bag thus formed. Once the product has been filled, the filled bag is separated from the tube and dropped. During this fall, the filled bag is shaped by the shaping means so that its cross-sectional area approximately corresponds to the internal cross-sectional area of the receiving box on the conveyor means. The filled bags are then stored in a storage box at a predetermined receiving location on the conveyor means. When the filled bag is stored in the storage box, the loaded storage box is moved on the conveyor means by the means for driving the conveyor means, and the empty storage box for storing the new filled bag is moved to a predetermined position. Move it to the receiving position. In the above operation, the forming means has a gap formed between its lower end and the opening of the storage box, and a gap is formed between the lower end of the filled bag suspended and held within the forming means and the opening of the storage box. Since it is fixed at a position where a gap is formed between the bags, it is possible to form the bag without having to enter into the storage box and rise from the storage box, unlike conventional forming devices (guide members). , the product can be filled, the filled bag can be loaded into the storage box, and the filled storage box and the empty storage box can be moved. Therefore, the operating speed is improved over conventional devices. The second invention is based on the action of the first invention,
When the cut filled bag falls inside the forming means, it comes into frictional contact with the forming means and the air inside the storage box due to the effect of the airflow flowing downward on the side of the filled bag by the blow-down means. The negative effects caused by the cushioning effect are reduced, and the falling speed can be increased. In the third invention, in the action of the second invention, while the filled bag is suspended and held by the forming means,
The forming means is vibrated by the vibrating means. Thereby, the molding of the filled bag is performed well over the entire bag. Therefore, the filled bag can be smoothly inserted into the storage box. In the fourth invention, in the operation of the first invention, when the filled bag is loaded into the storage box, the bag is lowered into the open end of the storage box and the closing member at the top of the storage box is deflected outward and held. let Therefore, the filled bag can be smoothly inserted into the storage box. (Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of an embodiment of the present invention, FIG. 2 is a side view seen from the right side of FIG. 1, and FIG. 3 is an enlarged front view of the main parts of the embodiment. For convenience of explanation, the embodiments shown in these figures are based on the first embodiment described above.
Although all the constituent elements of the fourth invention are included, various types of devices according to the first to fourth inventions can be constructed by appropriately selecting constituent elements as necessary. First, an overview of this embodiment will be explained with reference to FIGS. 1 and 2. The frame 10 vertically holds a hollow filling mandrel 12 into which flexible sheet material 14 is fed to form a continuous tube over the mandrel, with a hopper 16 above it for feeding the material to be packed. To support. The lateral sealing elements 19 form continuous lateral seams. The mover 18-18 moves the formed tube downwardly over the mandrel 12. The sealing section 20a and the cutting section 20b each shape the tube to the length of the bag and separate it into individual pieces. Tubular forming device (hereinafter simply referred to as forming device) 22
adapts the cross-section of the bag to the inside cross-section of the cardboard box in which it is to be loaded. The conveyor section 24 moves the cardboard box to the bag receiving position and moves the loaded cardboard box from this receiving position. The detailed configuration will be explained below. (A) Sealing section 20a, cutting section 20b First, the sealing section 20a will be explained.
FIG. 5 is a sectional view of essential parts of the sealing part 20a and the cutting part 20b. In the figure, sealing means 20a
has a pair of opposing jaws 68-68 held for horizontal reciprocating movement toward and away from each other, the vertically disposed flat surfaces 70-70 engaging the front and back sides of the tube and displacing them. Crimp to seal a short portion of the tube between the top and bottom of the jaw, as shown in FIG. A sufficient depth in the longitudinal direction of both jaws 68-68 is taken, and the middle of the upper and lower boundaries of the sealing area formed thereby is cut to form a lower end seal of the upper jaw pouch and an upper end seal of the lower jaw pouch. Adapt it as follows. The cutting means 20b consists of cutting blades 72-72 which are fitted into the jaws 68-68 and, after the jaws have engaged each other, are moved horizontally to make the cut in the sealed section. When using this type of construction, immediately after the jaws have retracted, the submaxillary pouch is released and thus falls out of the forming device 22 into the cardboard box. It may be desirable to leave the top of the bag below the jaws open until it is loaded into the carton, in which case the lower portion of the cutting blades 72-72 of the jaws 68-68 may be Chamfer as shown in Figure 5A so that sealing is only done on the upper side of the cutting blade. The bag below the cutting blade is not sealed, so that the length of the bag formed by cutting the tube remains open at its top and falls through the guide means into the carton. In the case of such an operation, the means 10 shown in FIGS.
1 (details of which will be described later) are provided to seal the open upper ends of the bags within the carton after the carton has been moved away from the lower end of the mandrel by the conveyor means 24. In FIG. 5, the upper side of the sealing jaws 68-68 is provided with flat surfaces 74-74 which are adapted so that the lower ends of the bag on either side of the seam rest on these flat surfaces during the filling operation. The sealing jaw 68-6 is closed until the bag is completely filled with an appropriate motion design.
8 with the bottom seam and the engagement time is long enough to allow the seal to set before the sealing jaws retract to allow the bag to fall into the lower carton. complete. As already pointed out, the advantage is that the bag is formed with a uniform cross-section over its entire length. This provides maximum filling capacity and maximum bag length even when the bottom seal is pillow-like. After the tube is laterally sealed to form the bottom of the bag and the upper portion of the seal is filled with a quantity of particulate material, the tube is placed in a forming device 22 with the filled portion described below. is lowered until it reaches
The cross section of the forming device 22 approximately corresponds to the inner cross section of the cardboard box into which the bags are charged;
After being suspended in the pipe, it is cut from the upper tube section and falls into a cardboard box resting on a conveyor. (B) Molding device 22 Next, the molding device 22 will be explained. Second
As can be seen from the figure, the forming device 22 has a gap formed between the open upper end of the cardboard box C on the conveyor section 24 and the lower end of the forming device 22, and the bottom of the bag suspended in the forming device. Ball box C
is fixed so that a gap is formed between the open upper end of the This fixed position of the molding device 22 is one of the features of this embodiment (common to the first to fourth inventions), and this allows the molding device 22 to enter and rise into the cardboard box like a conventional molding device. The first problem of the prior art described above is solved. That is, since the forming device 22 is fixed at the above position, the cardboard boxes C on the conveyor section 24 can be freely moved while the filled bags are suspended in the forming device 22. The speed at which filled bags are inserted into the cardboard box C is improved. As shown, the forming apparatus 22 has a pair of opposed channel members 26-26 which are below the sealing and cutting means but above the open top of the carton resting on the conveyor 24 below. is held in a certain position. Figure 2A shows the forming means 2
FIG. 2 is a horizontal sectional view of FIG. As shown,
Each channel 26 has side walls 28 and orthogonally arranged front and rear walls 30-30 which engage the front, rear and sides of the filled bag. channel 26
-26 is held by an L-shaped bucket member 34-34 between the forward ends of a pair of laterally spaced horizontal arms 32-32, as shown in FIG. 26, whose horizontal arms are adjustable and laterally movably secured to the forward ends of the arms 32-32, thereby reducing the spacing between the channel members 26-26, i.e. the section formed by the channel members 26-26. Area can be changed. The rear ends of both horizontal arms 32-32 are attached to a mounting panel 36 with relatively thick blocks 38-38 of rubber-like material interposed between them and the frame. By supporting in this way, the upper end of the molding device 22 is located directly below the sealing part 20a and the cutting part 20b,
Further, the lower end of the forming device 22 is fixed to the open upper end of the cardboard box C on the conveyor section 24 so as to form a gap as described above. Here, the forming device 22 ideally has a cross-section that substantially corresponds to the inner cross-section of the carton so that the bag adapted to the forming device 22 can be smoothly placed into the open top of the carton. Slide it into. However, in reality, it is desirable to make the cross section of the forming device 22 slightly smaller than the inside cross section of the cardboard box, and this is achieved by attaching the channel-like members 26--26 that make up the forming device 22 so as to be adjustable relative to each other. Molding device 22
By reducing the cross-section of the bag and therefore the cross-section of the bag before it falls into the carton C, a narrow interstitial space a in FIG.
Frictional contact between the surface of the bag and the inner wall surface of the carton C, which would tend to retard the movement of the bag into the carton C as already mentioned, is avoided. At the same time, air trapped between the bottom of the bag and the bottom of the carton C, which tends to impede the free descent of the bag within the carton, can escape upwardly through the bag surround. The molding device 22 having the above configuration can be further configured in combination with any one or any plurality of the baffle plate elements 40-40, the blowdown members 90-90, and the vibration device 23. These will be explained in detail below (B-1) Deflector plate element 40-40 The deflector plate element 40-40 is connected to the molding device 22.
It is pivotally attached to the lower ends of both sides. This baffle plate element 40-40 is one feature of this embodiment (corresponding to a feature of the fourth invention). FIG. 4 is a side view of the portion shown in FIG. 3, viewed from the right. 3, the baffle element 40-40 is lowered into the open end of the carton C supported therebelow, and the closure member 42-42 on the top of the carton C is moved outwardly from the top of the baffle element 40-40. The bag is held averted and placed so as to be guided into the open end of the cardboard box C. The baffle plate elements 40-40 are connected to the shaft 44-4.
4, this shaft is supported by bearings 46-46, 4
Bracket member 45-45 with 8-48
It is rotatably attached to the frame 10 of this device. Both brackets 45-45 have bolts 50-50 and slot means 52-52 which are horizontally movable toward and away from each other.
is attached to the horizontal bar 54 via the horizontal bar 54.
The ends of 4 are attached to vertically disposed posts 56-56 by bolts 58-58 which extend into slots 60-60 for vertical adjustment of the baffle. The baffle plate elements 40-40 move into and out of the operative position in response to the rotation of the shafts 44-44.
4 is rotated by a piston rod 64 whose one end is fixed to the shaft and the other end is an air cylinder 66.
This is done by arms 62-62 connected to 64. The baffle plate elements 40-40 are held in their retracted position before the carton C is moved into the operating position, and are retracted immediately after the bag has fallen into the carton C. In this way, using the baffle plate elements 40-40, the closure members 42-42 at the top of the cardboard box C
The bag is smoothly and quickly loaded into the carton C by holding it deflected outward from its top and guiding the bag inside the open end of the carton C. (B-2) Blowdown members 90-90 Frictional contact with the inside of the filled bag forming device 22 may prevent the filled bags from falling freely. In order to solve this problem, the blowdown member 90
-90 (corresponding to the characteristic parts of the second and third inventions) are provided as follows. That is,
As shown in FIG. 2A, channel member 26
- Front and rear blowdown members 90-90 consisting of vertically arranged tubes arranged in the space between
and vertically spaced, downwardly sloping ports 93-93 are provided on the member for directing jets of air downwardly toward the front and rear sides of the bag. In this way, this blowdown member 90-90
By using this, the falling of the filled bag is facilitated. (B-3) Vibration device 23 When the vibration device 23 is adapted to the cross section of the device 22 for forming filled bags, the device 2 for forming the bag is suspended.
By vibrating the bag 2, the bag is molded into the forming device 2.
It fits well into the cross section of 2. In order to apply such vibrations to the molding device 22, a vibration means (corresponding to the characteristic part of the third invention) 23 is provided as follows. In FIG. 4, vibrator 23 is bolted to mounting panel 36. In FIG. As already explained, since the panels are attached to the frame 10 via rubber blocks between them, considerable vibrations of the panels and thus of the forming apparatus can be achieved. (C) Conveyor section 24 Next, an example of the conveyor section 24 that moves empty cardboard boxes to a receiving position below the forming device 22 and removes loaded cardboard boxes C is shown in FIGS. 3 and 4. explain. The conveyor section 24 is connected to a belt 92, a portion of which is supported in a horizontal position on longitudinally spaced sprockets 94--94 of FIG. It consists of an electric motor M that drives a sprocket at one end of the motor. During continuous operation, a positioning device 96 automatically moves the cardboard box to an appropriate position on the conveyor in order to stop the cardboard box immediately below the forming device in synchronization with the operation of the bag cutting means.
, so that when the bag is released the cardboard box is in position to receive the bag. A stop 98 moves across the conveyor and pushes the carton onto the shelf at the rear of the conveyor, stopping the following carton. Pneumatic means are provided for actuating the positioning device and stop, and air is supplied to them by means of valve means 104,106. Alternatively, the belt may be moved intermittently with the aid of indexing means to move the boxes one at a time into a position below the forming device. When using indexing means,
The belt is provided with means for holding the cardboard boxes at equal intervals. For example, as shown in Figure 4A,
The belt 92 is provided with mutually longitudinally spaced spaces 92.1 for receiving and holding cardboard boxes at predetermined intervals. Both types of conveyors are provided with vertically spaced rails 108-108 on both sides to guide the cartons and prevent them from tipping over. Furthermore, in this embodiment, air that becomes an obstacle to the free descent of the bag inside the cardboard box C is exhausted. The exhaust from this cardboard box C is through the bottom exhaust port as shown in FIGS. 7 to 9. 8 and 9, the belt 92 is narrowed and the cardboard box is placed on the belt with its end or dust flap resting on the belt and its side or closing flaps folded downward. The space between the adjacent ends of the dust flap acts as an air outlet. As shown in FIG. 9, the cardboard box is placed on the belt with the dustproof flap and one closure flap resting on the belt and the other closure flap folded downward. The space between the dust flaps exposed by the downwardly bent closure flap provides an air outlet. Next, the operation of the above configuration will be explained. First, the flexible sheet material 14 is placed on the mandrel 1
2 to form a continuous tube on the mandrel 14. This continuous tube is provided with lateral sealing by lateral sealing elements 19. The tube thus formed is moved downward by the moving section 18-18. The tube is then laterally sealed by a seal 20a to form the bottom of the bag, and the portion of the bag above the seal 20a is filled with a quantity of particulate material. When the filling is completed, the tube is lowered until the filled portion reaches the inside of the forming device 22, and is vibrated by the vibrating device 23 while being suspended within the forming device 22. At this time, a predetermined amount of granular material is filled into the next bag portion above the sealing portion 20a. on the other hand,
During this time, the empty cardboard box C is moved to a receiving position below the forming device 22 by the action of the conveyor section 24. Of course, at this time, the loaded cardboard box C is moved from the receiving position. Next, the filled bag suspended within the forming device 22 is cut by the action of the cutting section 20b and falls. At this time, due to the action of the blowdown part 90-90 and the port 93-93,
Air jets are directed downwardly against the front and back sides of the bag. Therefore, the filled bag quickly falls and is loaded into the empty cardboard box C. At this time, due to the action of the baffle plate elements 40-40, the closing members 42-42 at the top of the carton are held in an outwardly bent shape. In this way, the bag is formed, the material is filled and the filled bag is placed in the carton. Next, the configuration of the apparatus in which the top of the bag is left open until the bag is inserted into the cardboard box will be described with reference to FIGS. 10 and 11. For this purpose, sealing means 101 for sealing the open end, means 107 for folding the sealed end into the carton, and means for closing the ends of the carton and the closing flaps on both sides are provided. Referring to FIGS. 10 and 11, when the cardboard boxes loaded with bags are conveyed from the lower end of the forming/filling device to the right by the conveyor 24 as shown in FIG. The flaps are opened by spaced parallel folding rails 111-111. The sealing means 101 consists of jaws 113-113 similar to those shown in Figures 5 and 6A, both of which are arranged to reciprocate in a horizontal plane above the line of the top of the container moving on the conveyor. Ru. The open top of the bag enters between the separated jaws and the photocell
A detector consisting of a PC causes the jaws to occlude at the upwardly projecting top of the bag at the appropriate time, thus sealing the top. When the jaws meet, they push apart the end wall closure flaps, holding the leading closure flaps in a downwardly displaced position, and when the jaws retract, the pneumatic plunger 115 is depressed and the position shown in FIG. Engaging the leading closing flap in a nearly horizontal position as shown, and as the carton continues to move further, the leading closing flap engages the underside of standoff rails 117-117 and is held downwardly. Folding blade 119 with an inclined end 121 supported above the line of travel at the top of the carton
Then, the upwardly projecting sealing top of the bag is folded and placed flat into the open top of the cardboard box. At the same time, the pair of rollers 123a, 123b and the lower roller 12
The adhesive is applied to the underside of the rear closing flap of the carton by means of a pot 125 supplying adhesive to 3a. Beyond the folding and gluing means there are means 127 for engaging the underside of the pre-closing flap to fold it back and lower it over the top of the carton. At this point, the tip of the cardboard box intercepts another photovoltaic cell P'C', and a single turn clutch 131 actuated by a solenoid
33 and folds it forward and lowers it onto the open top of the carton, moving both the leading and trailing closing flaps under the rail 135. As the carton advances further, both the leading and trailing closure flaps engage the spaced folding rails 137-137, which first move the adhesive-applied trailing closure flaps inwardly onto the end flaps. This acts to fold and then fold the leading closure flap onto the adhesively applied upper side of the trailing closure flap. said one or more closure members folded downward, e.g. by adhesive application means as described above, for folding and sealing said one or more closure members of the bottom folded cardboard box bottom; An adhesive is applied to the box and the carton is advanced to a push-down rail, such as the one described above, below a push-down rail for folding the one or more closure members upwardly against the bottom. During one operating cycle, a pouch is formed above the sealing jaw, its lower end is closed and its upper end is opened, and a pouch is formed below the sealing jaw, its lower end closed. Its upper end can be closed or open. The filling operation takes place when the sealing jaws are closed, and the cutting takes place after the sealing operation. After filling, the sealing jaws and cutting blades are retracted, allowing the released bag to fall into the carton below, and the filled bag descends for sealing and cutting of subsequent bags. . Vibrations of the bag are made when the bag is within the guide means. If the top of the bag is left open, the top is sealed while in the carton during the movement of the carton away from the mandrel, and the closure flap is folded over the top of the carton. be caught. The configuration example of the device according to the present invention has been described above. In the above explanation, some operating functions, namely filling operation, sealing/cutting operation, protrusion of the baffle plate at the lower end of the forming device, injection operation, movement of the conveyor, and operation of the positioning means and gate, are all synchronized. The filling of the bag with a constant amount of particulate material, controlled by a limit switch, or perforation tape, or a combination of limit switch and perforation tape, or equivalent means, so as to maintain and carry out the proper order; Ensuring sealing, cutting, adaptation to the cross section of the forming device by vibration for a suitable time, loading of the bag into the carton by releasing it, and timely advancement of the carton to the bag-receiving position when the bag falls from the forming device. be done. (Effects of the Invention) As described above, according to the present invention, the following effects can be obtained. (b) According to the first invention, the forming means is suspended within the forming means with a gap formed between the lower end of the forming means and the opening of the storage box in the storage position. Because it is fixed at a position where a gap is formed between the lower end of the filled bag and the opening of the storage box, it is difficult to enter the storage box and rise from the storage box, unlike the conventional molding device (guide member). The bags can be formed, filled with product, loaded into storage boxes, and filled and empty storage boxes can be moved without any action. Therefore, the operating speed is improved over conventional devices. (b) According to the second invention, in addition to the first invention, blowing down means for injecting airflow downward from the sides of the bag is provided in the forming means, so that the effect of (a) above is not achieved. In addition, the negative effects of frictional contact with the molding means and the cushioning effect of the air in the storage box can be reduced, and the falling speed can be increased. The invention is particularly effective when the granular material to be filled is lightweight. (c) According to the third invention, in addition to the second invention, there is provided a means for vibrating the forming means to adapt the suspended filled bag to the cross-sectional area of the forming means, so that the above (b) is achieved. In addition to the effect, the filled bag can be formed well throughout. The invention is particularly effective when the particulate material to be filled is lightweight and bulky. (d) In addition to the first invention, a fourth invention is a molding means that is positioned at the lower end of the forming means and can be lowered into the open end of the storage box, and deflects the closing member at the top of the storage box to the outside. Since the holding means is provided, in addition to the above effect (a), the filled bag can be smoothly inserted into the storage box. According to the present invention, the operating speed is improved by about 60% at most compared to the device disclosed in the above-mentioned document.
