DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic powder processing apparatus, and more particularly, to an automatic processing apparatus capable of automatically sucking and extracting powder from a powder bag having a horizontal upper surface opened and sending out an empty bag. The present invention relates to an automatic powder processing apparatus.

[0002]

2. Description of the Related Art A wide variety of powdered substances (powder) are used in a wide variety of industrial fields such as the food industry, the pharmaceutical industry, and the chemicals industry, depending on the purpose. The powder is usually filled and sealed in a bag made of paper, cloth, or another material having a suitable softness in a pure state in which a foreign material is not mixed in a flour mill.

[0003] In each of the above-mentioned industries using powders of various components, powders may be used alone depending on the purpose of use of the powder as a raw material.
Alternatively, a plurality of different types of powders are mixed and then variously processed to produce a product. To this end, it is necessary to form an opening surface in the powder bag in order to take out the powder from the powder bag.
Conventionally, the simplest means for forming an opening surface is to unwind the sewing thread closing the opening of the powder bag, cut the sewing thread using a knife, open the opening widely, or An appropriate portion of the bag surface close to the yarn was cut with a knife to form an open surface. Then, the powder bag is lifted and the powder is put into the container such as a hopper from the opening surface.

[0004]

However, since fine particles such as dust and other dust adhere to the surface of the powder bag, when the powder is charged, the dust and dust are collected together in the container. There was a fear of entering. In particular, when the powder bag has a plurality of layers such as double and triple layers, there is a possibility that dust and dirt entering between the layers may enter the container.

[0005] Usually, powder bags filled with powder are stacked in a horizontal state at the time of storage or transfer, but the powder bags must be set up by the above-mentioned opening means. But,
Since the powder bag has a considerable weight, it was very hard work for an operator to stand the powder bag upright and perform the opening operation while holding the bag. In addition, since the shape of the powder bag cannot be specified, when performing the opening work in the upright state, after forming the opening surface, the shape of the bag may be deformed and powder may spill out from the opening surface, Powder was sometimes wasted.

Therefore, for example, an opening is formed on the upper surface in a state in which a powder bag is erected, as disclosed in JP-A-6-32334 and JP-A-6-144430 provided by the applicant of the present invention, and powder is formed from the opening. Although a device for removing the body or automatically sucking the powder is provided, even in such a device, the powder bag in a horizontal state must be set up, and a device for that is required. Was.

The present invention has been made in view of the above-described conventional bag-opening technique of powder bags, and transfers the powder bags in a stored horizontal state, and holds the state to open the upper surface (bag opening). In view of the fact that it is desirable to carry out
The bag opening apparatus shown in No. 334 pays attention to the fact that an opening surface can be formed using a cutter on the upper surface of a powder bag placed in a horizontal state, and then the powder having the horizontal upper surface opened in a pretreatment step. It is an object of the present invention to provide an automatic powder processing apparatus capable of automatically sucking powder from a bag and transferring the sucked powder to, for example, a processing plant and automatically discharging empty bags.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the whole of a first embodiment of the processing apparatus of the present invention. In FIG. 1, reference numeral 1 denotes a tray for storing powder bags. This tray 1
It has an opening 2 capable of receiving a powder bag A in a horizontal state, and has a tapered inclined side surface 3 formed downward from the opening 2 toward the center.

As an example of the shape of such a tray 1, a trapezoidal rectangular body as shown in FIGS. 1, 2 and 3 can be used. That is, the tray 1 has a rectangular opening 2 on its upper surface capable of receiving the powder bag A in a horizontal state, and the inclined side surface 3 is formed from each of the four sides of the opening 2 toward the center downward. The formed whole has a square trapezoidal shape. Further, as another example, the rectangular inclined side surface 3 of the tray 1 is drawn into a conical shape tapered downward. For example, as shown in FIG. A well-known angle-round pyramid shape in which is the inclined side surface 3 of the cone can be used.

The tray 1 is divided into three by two separation spaces 4 formed along the direction of transport of the powder bag A shown by the arrow X in FIG. 2, and each of the divided bodies 1a, 1b and 1c is divided into a plurality. Are fixed at the same height as a whole and in a horizontal state via the supporting legs 5, and the gantry 6 is connected to the base 8 via a plurality of springs 7.

The gantry 6 is formed in a rectangular shape by a plate or a frame made up of a plurality of beams, and a known vibration generator 9 is installed on the lower surface at the center. Therefore, when the vibration generator 9 is operated, the gantry 6 vibrates due to the vertical expansion and contraction of the spring 7 and the right and left swing, and the vibration force can be transmitted to the entire tray 1.

A powder suction nozzle 10 is provided in an upper space facing the center of the tray 1, and a suction nozzle 10 having a suction port on a lower surface is provided with a suction source (not shown) using a known blower, bag filter, hopper, or the like. ) Are connected by a pipe 11. The suction nozzle 10 has a lifting mechanism B
This allows the tray 1 to move up and down. The elevating mechanism B includes a motor 13 mounted on the side of the support 12.
A ball screw 14 directly connected to the vehicle, a movable body 15 movable up and down along the ball screw 14, and a movable body 15
And a guide body 16 connected to the main body.

The ball screw 14 is formed by forming a thread groove on the outer peripheral surface of a metal shaft, and the moving body 15 is screwed into the ball screw 14. A conventionally known one can be used. . Further, a plate-shaped guide 16 connected to the moving body 15 is disposed in parallel along the column 12, and the guide 16 is a pair of upper and lower guides facing the inside thereof, that is, facing the column 12 side. Each guide piece 16a is slidably fitted on a guide rail 17 formed on the side surface of the column 12.

Since the lifting mechanism B has the above configuration, if the motor 13 rotates the ball screw 14, the moving body 15 moves up and down along the thread groove of the ball screw 14.
Since the guide piece 16a is connected to the guide rail 17 in a fitted state, the guide body 16 also moves up and down together with the moving body 15. Therefore, the moving body 15 connected to the guide body 16 moves vertically without rotating. Since the guide 16 and the suction nozzle 10 are connected via the horizontal connection arm 18, the suction nozzle 10 also moves up and down as the moving body 15 moves up and down.

Below the tray 1, a pair of transfer members 19 are provided facing the separation space 4. For example, the transfer member 19 constituted by a chain conveyor that can be circulated receives the powder bag A having the horizontal upper surface opened in the pretreatment step, transports the powder bag A to a predetermined position above the tray 1, and stores the powder bag A in the tray 1. The empty bag from which the powder has been sucked is lifted horizontally above the tray 1 and sent out to the next processing step.

As shown in FIG. 2, both transfer members 19 have a length greater than the width of the tray 1 and
And is located below the separation space 4 in the normal state. The pair of transfer members 19 that can circulate in synchronization with each other are
The transfer member 19 can protrude above the tray 1 through the separation space 4.

The lifting mechanism C includes a cylinder 21 fixed to the side surface of the column 20, a support plate 22 having a pair of upper and lower guide pieces 22a, and a support plate 22 provided on the side surface of the column 20.
and a guide rail 23 in which a is vertically slidably fitted.

As shown in FIG. 2, a horizontally long support plate 22 is arranged vertically inside the support column 20 along the transfer member 19, and the support plate 22 is connected to the rod of the cylinder 21 via the connection plate 24. The connection allows the rod of the cylinder 21 to move up and down by extending and contracting the rod up and down. When the support plate 22 moves up and down, the guide piece 22a moves along the guide rail 23, so that the support plate 22 moves smoothly in the vertical direction without rattling.

The two horizontal and parallel rotating shafts 25 directly connected to the sprockets 19a and 19b before and after circulating the chain constituting the transfer member 19 have their bases connected to the support plate 22 via bearings 26, respectively. The pair of left and right transfer members 19 are simultaneously held in a horizontal state by two rotating shafts 25.

One rotating shaft 25, for example, rotating shaft 25a
As shown in FIG. 2, the drive motor 27 fixed to the side surface of the support plate 22 is connected by a chain. If the rotation shaft 25a is rotated by the motor 27, the pair of transfer members 19 are synchronized and the same. In the direction (arrow X direction). In the figure, reference numeral 28 denotes an auxiliary arm, which protrudes obliquely upward from the support plate 22 and has an upper end connected to the rotating shaft 25 via a bearing 29 so as to support the rotating shaft 25 from below. I have.

The device according to the present invention has the above-described configuration. Next, a use state will be described. As shown in FIG. 5, the powder bags A sent horizontally from the storage location by the transfer conveyor 30 are aligned in the front-rear and left-right directions by the positioning conveyor 31, and the bags A are transferred one by one to the above-described conventional bag opening device 32. It is fed and the horizontal upper surface is opened by the cutter.

The powder bag A having the upper surface opened is sent to the tray 1 of the apparatus of the present invention in a horizontal state. At this time, as shown in FIG. The tray 1 is located above the opening 3. The powder bag A sent from the bag opening device 32 by, for example, a chain conveyor or a belt conveyor is placed on the end of the traveling transfer device 19, and the transfer device 19 transfers the powder bag A to the tray 1 To a predetermined position.

When the powder bag A reaches a predetermined position on the tray 1, the traveling operation of the transfer member 19 is stopped, and then the transfer member 19 is moved by the lifting mechanism C with the powder bag A mounted thereon in the normal position shown in FIG. The powder bag A is left in the tray 1 on the way, and is stored as it is.

Since the tray 1 is inclined downward from the opening 3 toward the center as described above, the powder bag A has a flat upper surface but a lower surface as shown by the dashed line in FIG. The state is along the inclined side surface 3 of the tray 1, and the center is at the lowest position. The powder contained in the powder bag A naturally slides down toward the center along the inclined side surface 3, but the vibration generator 9 applies vibration to the tray 1 via the gantry 6 to force the powder. Will slide down towards the center. In this manner, the suction nozzle 10 is lowered by the elevating mechanism B while applying vibration to the tray 1 (the powder bag A), and the nozzle 10 is inserted through the opening of the powder bag A as shown in FIG. Activate the source and aspirate the powder.

When all the powder is sucked, the upper surface of the powder bag A becomes
As shown by the two-dot chain line in FIG. 6, the entire shape is maintained only by the state where the central portion is depressed. After sucking the powder, the suction nozzle 10 is raised to a predetermined position by the lifting mechanism B, and the transfer member 19 is raised by the lifting mechanism C. When the transfer member 19 is raised, the empty bag A1 in the tray 1 is lifted. Of the tray 1 and lift it up, and push it up above the opening 3 of the tray 1 as shown in FIG.

In this state, the transfer member 19 is driven and circulated by the motor 27, and the empty bag A1 is sent in the direction of extension of the transfer direction of the powder bag A. As shown in FIG. After weighing in 33, it may be sent to the storage place 34 of the empty bag A1.

By repeating the above operation, the powder can be sucked from the powder bag A, and the empty bag A1 can be automatically sent out. The driving, stopping, and the like of the entire apparatus of the present invention, such as the circulating operation and stopping of the transfer member 19, can be automatically and continuously performed by a control device (not shown).

1 and 6, reference numeral 35 denotes an auxiliary plate. The auxiliary plate 35 has the same inclination angle as the inclined side surface 3 of the tray 1 and has a length substantially equal to the width interval of the tray 1. The cylinder 36 installed between the supporting legs 5 allows the tray 1 to advance and retreat from the lateral direction toward the lower surface of the separation space 4 of the tray 1.

The auxiliary plate 35 is normally pulled toward the cylinder 36 as shown in FIG. 1, but as shown in FIG. 6, the powder bag A is stored in the tray 1 and the transfer member 19 is moved to a predetermined position. When it is lowered, it is advanced by the cylinder 36 to close the lower surface of the separation space 4. Therefore, the powder bag A does not protrude below the tray 1 from the separation space 4, and the bottom surface of the powder bag A is kept parallel to the inclined side surface 3 of the tray 1, so that powder may accumulate on the way. In addition, all powder can be sucked.

In the above description, the suction nozzle 10 can be moved up and down with respect to the tray 1 by the elevating mechanism B. However, the present invention is not limited to this. For example, the suction nozzle 10 can be moved up and down by the same mechanism as the elevating mechanism C. Alternatively, a simple lifting mechanism using only the cylinder may be used.

Further, the bag-opening operation of the powder bag A in the pretreatment stage of the powder processing by the apparatus of the present invention is not limited to the case where the above-mentioned known bag-opening device is used. It may be used, and in the simplest case, an operator may manually form an opening surface on the horizontal upper surface of the powder bag A with a cutter. Which device or means is adopted can be arbitrarily selected.

FIG. 8 shows a second embodiment of the apparatus of the present invention, and the same parts as those in the above embodiment are denoted by the same reference numerals. The present embodiment is characterized in that a press-contact plate 37 which can be moved up and down is installed between the tray 1 and the suction nozzle 10 in a horizontal state, and a cylinder 38 for pushing up an empty bag A1 is installed at a lower center of the tray 1. And

The press-contact plate 37 having at least the same plane area as the opening 2 of the tray 1 can be moved up and down along the column 20 by an elevating mechanism D having the same structure as the elevating mechanism C. That is, the cylinder 39 fixed to the side surface of the column 20, and the guide plate 4 having a pair of upper and lower guide pieces 40a.
0 and a guide plate 40.
“a” is vertically slidably fitted into the guide rail 23 provided on the side surface of the support column 20, and the press contact plate 37 has its base fixed to the guide plate 40 in a horizontal state. Therefore, the press contact plate 37 moves up and down in the horizontal state due to the expansion and contraction of the cylinder 39 rod.

As shown in FIGS. 8 and 9, the cylinder 38 is located below the center of the tray 1 in the middle of the transfer members 19 on both sides, and projects horizontally from the support plate 22 supporting the transfer members 19. The arm 42 is connected to the tip of the provided arm 42 in an upward state. The cylinder 38 can be moved up and down together with the transfer member 19, rises to a predetermined height position in the tray 1 through a hole 43 formed in the center of the bottom surface of the tray 1, and then moves to the tip of the rod of the cylinder 38. The attached push-up plate 44 can project above the tray 1 together with the transfer member 19.

In the above configuration, the powder bag A whose horizontal upper surface is opened by the bag opening device 32 in the pre-processing stage is accommodated in the tray 1 through the same process as in the above embodiment, and the powder is removed by the suction nozzle 10. After the suction, the suction nozzle 10 is raised to a predetermined position to push up the empty bag A1 above the tray 1 by the pair of transfer members 19, and the cylinder 38 is also raised by the support plate 22 together with the transfer members 19.

The height of the upper surface of the cylinder 38 depends on the transfer member 1.
9 is lower than the top height of the cylinder 9
8 enters the tray 1 from the hole 43 and pushes up the central lower surface of the empty bag A1, but when the transfer member 19 protrudes above the tray 1 and pushes up the empty bag A1, the cylinder 38 itself rises above the tray 1. It does not protrude and stops in the middle of the tray 1. For this reason, the push-up plate 44 is extended independently, and the push-up plate 44 and the transfer member 19 are set at the same height position, so that the empty bag A1 has three points of the pair of left and right transfer members 19 and the center push-up plate 44. To push the tray 1 upward.

At this time, as shown in FIG. 10, if the press contact plate 37 is lowered to a predetermined position, the upper surface of the pushed empty bag A1 is pressed against the lower surface of the press contact plate 37. As a result, the empty bag A1 is in a flat state. When the empty bag A1 is crushed in this manner, the press-contact plate 37 rises to a predetermined position and the push-up plate 44 descends to the cylinder 38, and the transfer member 19 operates to remove the flat empty bag A1 from the post-processing step. (Measurement process).
In order to move the suction nozzle 10 up and down, a hole 45 through which the suction nozzle 10 can pass is provided through the pressure contact plate 37.

The transfer member 19 is provided with the empty bag A as described above.
When 1 is sent to the post-processing step, it descends to a predetermined position, but at the same time, the cylinder 38 also descends below the tray 1 through the hole 43.

In FIG. 8, reference numeral 46 designates a holding member for holding the opening of the powder bag A, and has a holding plate 48 which moves up and down by a pair of cylinders 47 installed on the upper surface of the press contact plate 37, and the lower surface of the holding plate 48. A pair of cylinders 49 installed symmetrically facing inward are connected to holding members 50 each formed of a slender plate or wire having lower ends bent outward in a hook shape, respectively.

The holding plate 48 is in a state parallel to the pressing plate 37, and a hole 51 through which the suction nozzle 10 passes is formed at the center thereof. The tip of each holding material 50 passes through a hole 45 formed in the pressing plate 37. It can protrude below the pressure plate 37. The holding material 50 moves in the left and right opposite directions in FIG. 8 and the suction nozzle 10 passes through the space therebetween.
5 is desirably formed somewhat larger than the hole 51, but the hole 51 and the hole 45 may be the same size.

In the above configuration, when the powder bag A whose horizontal upper surface is opened by the bag opening device 32 in the pretreatment stage is stored in the tray 1 through the same process as described above, as shown in FIG. The pressing plate 37 is lowered to a certain height position by the lifting mechanism D, and then the holding plate 48 is lowered by the cylinder 47 to put the tip of the holding material 50 into the bag from the opening surface of the powder bag A.

In this state, if the holding members 50 are horizontally moved in the left and right directions by the cylinder 49, the bent lower end portion is held in contact with the lower surface of the powder bag A in the opening surface. When the suction nozzle 10 sucks the powder, the upper surface of the powder bag A is sucked downward by the suction force and becomes concave, but since the holding material 50 holds the opening surface of the powder bag A, Even when the suction nozzle 10 sucks the powder and the amount of the powder becomes small, the center of the upper surface of the powder bag A does not dent inward. Although not shown in FIG. 8, as shown in FIG. 9, in the present embodiment, both rotary shafts 25 are
And bearings 29.

FIGS. 12 and 13 show still another embodiment of the apparatus of the present invention, and the same reference numerals are used for the same parts as those in the above embodiments. In the present embodiment, the center divided body 1a of the tray 1 divided into three as described above.
Is further divided into two at the center, and the gantry 6 is divided into two at a position corresponding to the division surface of the divided body 1a.

That is, as shown in the figure, the inclined surfaces 3 on the four sides of the central divided body 1a are set to a steep angle, and the divided bodies 1b, 1
The inclined surface 3 of c has a gentle inclination angle.

When the tray 1 is configured as described above, when the powder bag A is stored in the tray 1, the four sides of the powder bag A are initially placed on the inclined surfaces 3 of the divided bodies 1b and 1c. When the tray 1 is vibrated by the generator 9, the powder bag A is divided into the divided bodies 1a.
The powder falls along the steeply inclined surface 3 and the powder concentrates at the central portion, so that the suction efficiency by the suction nozzle 10 is improved. The inclination angle of the four sides of the divided body 1a is 35.
５０50 °, the inclination angles of the four sides of the divided bodies 1b and 1c are 25 to 4
0 ° is optimal, and it is desirable that the inclination angles of 10 to 15 ° be different.
