Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dust supply device used in a horizontal rotary type dust filling and packaging machine that forms a bag from a long resin film by heat sealing, fills and separates a dust.
[0002]
[Prior art]
The continuous automatic dust packaging machine forms a large number of bags continuously on a long thermoplastic resin film, fills each bag with a predetermined amount of powder, seals each bag with a heat seal, and packs the powder. It is to be packed.
[0003]
As shown in FIGS. 8 and 9, the conventional rotary-type powder packaging machine rewinds the coil-shaped long film 90 by the rewinding device 8 and continuously transfers it to the sealing and filling mechanism. Then, while transporting the long film 90 horizontally, first, the film is bent into a U-shaped trough through a film guide 84, and then the lower ends of a number of chutes 3 arranged on a turntable are sequentially folded in two. Then, the sealing bars 20a and 20b of the sealing bar arranged in the same manner sandwich the both edges of the film together, and simultaneously perform a narrow heat seal in the width direction of the film. The width seal portions are formed at regular intervals in the longitudinal direction.
[0004]
The inside of the double film divided by a number of width seal portions 92 becomes a bag portion, and a number of bag portions 93 are formed continuously in the longitudinal direction. The upper edge portion of the bag portion 93 is open, and a fixed amount of the powder is cut out from the powder material supply means 6 through the opening of the basin, and is filled in each bag portion 93 by the chute 3.
[0005]
The film 91 in which the powder material is loaded in each bag portion 93 is continuously transferred from the sealing and filling mechanism to the upper edge sealing device 87, and the upper edge portion of the bag portion is continuously heat-sealed, and the edge sealing is performed. The part 94 is formed, and the inside of the bag part is sealed. Further, the film is transferred to a cutting device 89, the width seal portion 92 is cut, and each bag portion 93 is cut off to form a product 9.
[0006]
As an example of a rotary-type filling device, Japanese Patent Application Laid-Open No. 2001-122208 discloses a plurality of openable and closable sealing bars 20 arranged at equal intervals on the periphery of a turntable, and a vertically movable arrangement between adjacent sealing bars 20. There is disclosed a film sealing and filling mechanism including a large number of chutes 3 for feeding powder members and a chute shaft 34 for holding the chutes up and down. The chute shaft 34 extends through the turn ring, and the sealing bar 20 is fixed to the upper edge of the rotary drum 13.
[0007]
In this conventional machine, a rotary drum is supported by a bearing mechanism 131 so as to be rotatable around a fixed base. One outer circumference of a turn ring fixed to the outer circumference of the rotary drum is used as a gear 18b, and a gear of a drive shaft 19 is used. 18a, and is driven to rotate. According to the rotation of the rotary drum, the sealing bar 20 clamps the folded film 91 by the opening / closing operation and guides the film 91 around the turntable while heating the sealing bar to form a width seal portion at equal intervals in the film, Make a bag. At the same time, the lower end of the chute is inserted into the bag, the powder is filled into the bag, and then the chute is pulled out of the bag, and the film is released from the sealing bar. Then, it is transferred to the upper edge sealing device 87 as described above.
[0008]
[Problems to be solved by the invention]
In the conventional powder supply device, when rotating the rotating container, the bottom of the rotating container is fixed to and supported by the upper end of the rotating shaft penetrating the hollow portion of the base. This is a simple structure and convenient for supporting and controlling the rotation of the rotating container, however, just below the rotating container, as described above, a number of sealing bars and chutes of the sealing and filling mechanism. The rotating shaft of the rotating container has been a hindrance particularly in the replacement and adjustment of these sealing bars and chutes.
[0009]
The bottom of the rotating container is provided with a large number of cells attached to the bottom and a shutter for opening and closing the lower end opening of each cell. And the turntables and the like that support it have to be soiled, so it has been necessary to clean them frequently.
[0010]
Furthermore, in the conventional powder filling and packaging machine, since the sealing bar and the corresponding chute are fixed at a predetermined position on the periphery of the turntable of the above-described sealing and filling mechanism, the distance between adjacent sealing bars is reduced. Since the pitch between adjacent bags, that is, the width of the bag after cutting, is fixed, it is substantially difficult to freely change the bag pitch.
[0011]
On the other hand, a dust filling and packaging machine having a mechanism that allows the bag pitch to be variably adjusted with a single machine relatively easily can be considered. It is possible to change the bag pitch by changing the number of chutes and sealing bars by replacing the rotary drum with the arrangement of the rotary drum and the sealing drum.
[0012]
Another mechanism unitizes one sealing bar and one corresponding chute, and attaches a desired number of these sealing units to a rotary drum fixed to the main body of the sealing filling mechanism. However, it is also possible to change the bag pitch.
[0013]
However, when replacing the sealing bar, it is necessary to dispose the rotary shaft of the rotary drum and the rotary shaft of the rotary container so that replacement is easy. The supply device itself had to be structured so that it could be retracted from directly above.
[0014]
The present invention has been made in view of the above problems, and aims to provide a powder filling and packaging machine having a support mechanism that can be evacuated from a position above a sealing filling mechanism at any time during replacement or maintenance of a sealing bar or the like. is there.
[0015]
Another object of the present invention is to provide a powder feeder which can be easily retracted, does not hinder the work at the lower portion, and can easily rotate the rotary container.
[0016]
[Means for Solving the Problems]
The dust supply device of the present invention is a rotary container that receives the powder from the hopper, fills the container provided on the bottom plate, and puts the powder in the container into a chute, and a support that rotatably supports the rotary container. A rotating mechanism for rotating the rotating container, wherein the support is provided with a horizontal arm rotatably provided from an appropriate fixing member, and a frame fixed to the horizontal arm and rotatably supporting the outer periphery of the rotating container. Wherein the rotation mechanism includes a container gear provided around the rotary container, and a transmission member that meshes with the container gear and rotates the rotary container by a motor.
[0017]
In the powder supply device described above, the rotating container is supported by the frame, and the frame can be turned by turning the arm, and can be turned from the position immediately above the sealing and filling mechanism and from this position to the retracted position. The frame body rotatably supports the rotating container by appropriate means, provides a container gear around the rotating container, and rotates the rotating container by an appropriate transmission member.
[0018]
Since the support mechanism of the rotating container does not need to be supported by the rotating shaft from the base of the sealing and filling mechanism as in the related art, an appropriate space is formed in the lower part of the powder supply device including the rotating container, This is convenient for replacing a chute or a sealing bar or the like and other operations, and can facilitate turning and retreating of the powder material supply device.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
The powder supply device of the present invention is a device that is disposed immediately above the sealing filling mechanism and supplies a fixed amount of powder to each of the rotating chutes. In this position, the rotating container is supported while rotating.

Any member that can follow the rotation of the arm and transmit the rotation of the upper gear to the container gear may be used, and the shaft may include a universal joint.
[0024]
The motor is a power source for rotating the rotating container through the rotating shaft. Preferably, the motor is capable of variably adjusting the speed of the rotating container, and a servo motor may be used for this. The motor is also connected to the rotation shaft via a transmission, so that the rotation speed of the rotating container can be changed. In this way, by variably controlling the rotation speed of the rotating container, control is performed so as to synchronize with the rotation position and speed of the chute and sealing bar of the sealing filling mechanism, and the chute and sealing bar for changing the bag pitch are changed. Even if the interval is changed, there is an advantage that the above-mentioned synchronization can be easily controlled.
[0025]
The rotation motor can be used in common with a drive motor for rotating the turntable or rotary drum of the sealing and filling mechanism. The motor shaft of the single motor may be connected to the drive shaft of the rotary drum and the rotation shaft of the rotary container of the powder material supply device via separate transmission mechanisms. Even when the space between the chute and the sealing bar is changed by changing the gears or the like of the transmission mechanism, it is possible to mechanically synchronize the rotation position and speed of the chute and the sealing bar.
[0026]
The horizontal arm is preferably composed of an upper arm and a lower arm. Preferably, both the upper arm and the lower arm can support the rotating container frame. In this case, the transmission member includes a relay gear that is rotatably supported between the upper arm and the lower arm and meshes with the upper gear of the rotating shaft, and causes the relay gear to rotate the container gear.
[0027]

It is preferable that an elevating means which engages with the horizontal arm so as to be able to be pulled up or pushed up is fixed to the upper bracket or the lower bracket, and the elevating means moves the horizontal arm up and down along the guide shaft. With the horizontal arm raised upward, the upper arm and the lower support can be simultaneously pivoted about their axes.
[0028]
Further, the above-mentioned relay gear meshing with the upper gear of the rotating shaft is slidable and vertically slidable with the upper gear. For this reason, the upper gear makes the gear vertically long so as to be meshable, including the vertical movement stroke of the relay gear.
[0029]
The frame body rotatably supports the rotating container. For this purpose, the frame body and the outer periphery of the rotating container can be supported by a bearing, for example, a rolling bearing. A preferred embodiment includes at least three rolling rolls projecting inward from the frame, and the rolling rolls roll on the inner surface of the rolling groove provided on the outer periphery of the rotating container or the lower surface of the flange. A rotatable container is rotatably supported inside the frame. This is simple in structure, and the rotating container can be easily attached to and detached from the frame by adjusting the projecting distance of the rolling roll from the frame. A bearing for positioning the center of rotation is provided at the center of the frame, and a projection is provided at the center of the lower surface of the other rotating container so as to fit with the bearing. Can be surely positioned.
[0030]
The dust supply device of the present invention can be suitably applied particularly to a dust filling and packaging machine capable of changing the bag pitch by simply adjusting the number of sealing bars and chutes of the sealing and filling mechanism. The form of such a powder filling and packaging machine is a sealing unit in which one sealing bar and one chute are integrated, and a number of sealing units are freely fixed around the rotary drum but at equal intervals, Change and adjust the bag pitch by changing the number of sealing units around the rotary drum.
[0031]
In the form of another powder filling and packaging machine to which the powder supply device of the present invention can be applied, a rotary unit is prepared by attaching a required number of sealing bars and chutes to the rotary drum body in advance and integrating them. In some cases, the rotary unit itself is replaced with respect to the main body of the powder filling and packaging machine, thereby changing the number of sealing units and changing and adjusting the bag pitch.

【The invention's effect】
The dust supply device of the present invention is configured to receive a powder from a hopper, fill a container provided on a bottom plate, and rotatably support a rotary container that throws the powder in the container into a chute. Wherein the support comprises: a horizontal arm rotatably provided from the apparatus main body; and a frame fixed to the horizontal arm and rotatably supporting the outer periphery of the rotating container. Since the mechanism includes a container gear provided around the rotary container and a transmission member that meshes with the container gear and rotates the rotary container by a motor, a lower portion of the rotary container is associated with a sealing filling mechanism. Since there is no need to provide a special member, the powder supply device including the rotating container can be moved up and down and swung. In particular, during the operation of changing the number of sealing bars and chutes, the powder material supply device of the present invention can be retreated in a horizontal direction from above the sealing filling mechanism. The work of changing and adjusting can be easily performed.
[0054]
Similarly, since no special member is provided at the lower portion of the rotating container for associating with the sealing filling mechanism, the lower portion of the rotating container is provided with a lower cover to prevent unnecessary dropping of the powder material and sealing. Dirt on the filling mechanism can be prevented.
[0055]
The dust supply device of the present invention includes a fixed support in the support, and if the arm is disposed at the top of the support so as to be capable of horizontal rotation, the powder supply device is rotated around the support, and It can be easily retracted from above the sealing filling mechanism. This is convenient for replacement work of a sealing bar and the like, and other inspection and adjustment work of the sealing filling mechanism and the powder supply device.
[0056]
If a rotating shaft penetrating the inside of the support, and a transmission member for connecting the upper gear fixed to the upper part of the rotary shaft and the gear of the rotating container are provided, the support of the rotating container and the rotation of the rotating container via the support are provided. And the swiveling of the powder supply device around the column becomes possible. In addition, since this rotating shaft is separated from the sealing filling mechanism, the drive shaft for rotating the rotary drum is driven through the inside of the sealing filling mechanism, in particular, the inside of the cylindrical base supporting the rotary drum. The rotary drum can be directly or indirectly driven.Therefore, since the drive shaft is not disposed outside the rotary drum, it is necessary to replace the rotary drum or to replace the rotary shaft with a sealing bar around the rotary drum. There is an advantage that the work of replacing the chute is facilitated.
[0057]
The horizontal arm includes an upper arm and a lower arm, and the transmission member includes a relay gear rotatably supported between the upper arm and the lower arm and meshing with an upper gear of the rotating shaft. If the relay gear rotates the above-mentioned container gear directly or indirectly, the relay gear can be integrated with the horizontal arm and can be easily arranged, and the rotation of the transmission member can be easily performed with the rotation of the horizontal arm. There are benefits you can do.
[0058]
If the rotation speed of the rotary container is made variable by a servo motor, the number of sealing bars and chutes in the sealing and filling mechanism must be changed in order to change the bag-to-bag pitch. The adjustment of the change of the rotation speed of the rotating container can be easily executed by the servomotor.
[0059]
If the motor is connected to the rotating shaft of the column via a speed change mechanism and the speed of the rotation container is made variable by the speed change mechanism, the number of sealing bars and chutes is changed, and the rotation of the rotation container is changed. When the number of sealing bars and chutes in the sealing and filling mechanism is changed in order to change the bag-to-bag pitch, the necessary rotation container can be adjusted. Adjustment of the change in the rotation speed can be easily performed by the transmission mechanism.
