A mass transport device is described.

(Problems to be Solved by the Invention) However, in the former known one, it is not possible to collectively transfer the thin cartons that are thin and easily fall down to a required filling place.

Further, the one described in the official gazette cannot be adopted as a transporting means for a complicated structure and a thin one such as a flat carton, which is easy to fall over immediately, like the former one.

In addition, there has never been a thin carton such as a flat carton that can be easily collapsed at once by using a carrier air pipe to a required filling place.

It is an object of the present invention to provide a transfer device capable of transferring the above-mentioned transferred objects from the stock place to the contents filling place.

(Means for Solving the Problem) In order to achieve the above-mentioned objects, the present invention provides the following apparatus for conveying an object to be conveyed.

That is, a capsule that reciprocates by being guided by air along a guide rail provided in the transport air pipe is provided in the transport air pipe, and at the entrance of the transport air pipe, a large number of sheets stored in a returnable box are provided. Sheets such as flat cartons are stacked and aligned horizontally in a standing state, and a group of conveyed objects is sucked at the upper part while sandwiching the sheet-like bodies at both ends and collectively passed through the above. A suction head that is taken out of the box and transferred to the upper part of the inlet of the air pipe for conveyance, and sequentially receives the conveyed objects from the suction head and stacks them one by one from the lower one by its own weight. A magazine rack is provided to supply the capsules to the storage port, and at the end of the carrier air pipe, the capsules are turned over by the guide rails. Is a transporting device configured to receive the objects to be transported which are discharged by their own weight from the storage port of the capsule through the discharge port of the transport air pipe in a batch manner. .

(Embodiment) Hereinafter, as an embodiment shown in the drawings, the conveyance of a flat carton will be described as an example.

In the first place, in the transporting apparatus of the present invention, flat cartons that are grouped in units of several tens to several hundreds, that is, the transported objects are stored in several rows in a returnable box made of corrugated cardboard or synthetic resin, It is delivered to the factory that uses it.

At the production site of the factory where the flat carton is manually extracted from the returnable box in groups, and supplied to the packaging machine, it is general that the flat carton is delivered to a place far away from the place of use. The present invention is to pneumatically convey the flat carton to the delivery place and the use place by the capsule, and automatically supply the flat carton to the packaging machine at the same time.

When handling flat cartons in units of several sheets, there is no problem in handling, but when handling several tens or hundreds of sheets, that is, handling a large number of sheets as a group, the product label is printed on the surface. Since it is slippery and the weight is heavy, it becomes uneven and very difficult to handle.

Therefore, in the present invention, it is particularly necessary to take out a flat carton from a returnable box in units of several tens or hundreds of tens, and to supply the flat cartons to the capsules at a time. Therefore, a suction head device is required.

Also, when taking out flat cartons from capsules, in order to take out flat cartons in groups without breaking them apart, invert the capsules at the end of the transport air pipe to collect flat cartons in groups from the capsule. Therefore, a smooth and reliable discharge is possible.

First, the structure for removing a flat carton from the box will be described.

In FIG. 1, (1) is a stock conveyor,
A returnable box (a) shown in FIG. 8 containing a flat carton is supplied to this.

In this stock conveyor (1), a plurality of conveyors are arranged so that flat cartons of different types can be stocked. At the exit of the stock conveyor (1), one carrying box (a) is transferred to the next conveyor (2). There is a dividing device (3) for transferring to.

The dividing device (3) uses a hydraulic cylinder to move the return box (a) to 1
It is composed of a device for pushing up one by one, and the returnable boxes (a) taken out one by one from the leftmost stock conveyor (1) in FIG. 1 reach the left end of the transfer conveyor (2).
Here, the introduction pusher (4) is sent to the supply pusher section (5) as shown in FIG.

The returnable box (a) sent to the supply pusher (5) is laterally transferred to the flat carton take-out section (7) by the supply pusher (6).

In the flat carton take-out section (7), the flat carton is taken out from the carton box (a) by a lift described later and supplied to the flat carton supply section (9) of the transfer air pipe (8).

The returnable box (a) that has been emptied by taking out the flat carton is transferred to the empty box recovery conveyor (11) by the discharge pusher (10).

FIG. 1A shows the position of the introducing device and the positioner that perform the above-described operation. The introduction device and positioner position are A ₁ , A ₂ , A depending on the type of carton stocked on the stock conveyor (1).
_{There are three} similar introducer and positioner positions.

Here, the concrete structure of the take-out section of the carton will be described with reference to FIGS. 3 and 4, and the carton in the return box (a) sent to the supply pusher section (5) is
The lift cylinder (12) shown in the figure lifts the lift (13) step by step.

And, a group of flat cartons that are extruded to the rim of the returnable box (a) and horizontally aligned and stacked in the standing state,
The flat cartons at both ends thereof are clamped from the left and right by the claws (15) of the side holding arms (14) attached to the suction head (16).

The suction head (16) is connected to the blower by the suction pipe (17), so that the flat carton group is collectively clamped by the left and right claws (15) (15) and the upper part is sucked by the suction head (16). To be done.

Also, just as the claws that hold the flat carton group from the left and right are inserted into the return box (a), the return box (a) has a space (18) into which the claws are inserted as shown in FIG. is there.

The flat carton group as described above is taken out from the container (a) by suction of the claws (15) of the side holding arms (14) and the suction head (16), and the suction head (16).
As shown in Fig. 3, the rotating arm (1
Since it is supported by 9), it is supplied by the robot (20) to the supply magazine rack (21) of the carton supply section.

At that time, the flat carton group taken out by the suction of the side holding arm (14) and the suction head (16) and taken out to the carton supply section (9) is sucked by the suction head (16) at a predetermined position. By stopping the operation, it is separated from the holding arm (14) and loaded into the supply magazine rack (21).

The rotating arm (19) of the supply robot (20) that has been charged is returned to its original position again, the next flat carton group is nipped and lifted, and the operation of charging this into the supply magazine rack (21) is repeated. . Therefore, the return box (a) becomes empty, and flat cartons are stacked in the supply magazine rack (21).

Once flat cartons are stocked in such a supply magazine rack (21), one supply robot (2) can be installed without installing a supply robot (20) in each transfer line.
With 0), it becomes possible to supply flat carton groups to a plurality of transfer lines.

When all the flat cartons have been taken out, the lift (13) descends and the empty returnable box (a) is transferred to the empty box recovery conveyor (11) by the discharge pusher (10) and transported to the recovery location. To be done.

Next, a flat carton for each group, that is, a configuration for supplying an object to be conveyed will be described.

The above-mentioned structure is shown in FIGS. 5, 6 and 7, and the supply magazine rack (21) has a transport air pipe (8).
It stands upright on the entrance (8a) on the front edge of the.

As described above, the flat carton group (b) separated from the suction head (16) and the holding arm (14) is stacked on the supply magazine rack (21).

Then, the flat carton group (b) next to the lowest flat carton group (b) among the stacked flat carton groups (b) is pressed from the left and right by the carton pressing devices (23) and (23). The holding devices (23) (23) are composed of a pair of left and right hydraulic cylinders and a holding plate for their piston rods.

Therefore, the lowermost flat carton group (b) is in a free state, and the supply shutter (2) formed at the connection portion between the supply magazine rack (21) and the transport air pipe (8).
When 2) is opened, the lowermost flat carton group (b) supported by the supply shutter (22) is put into the capsule (24) housed in the transport air pipe (8).

The shutter (22) is a pair of left and right hydraulic cylinders (22a)
And its piston rod shutter plate (22b).

Further, the capsule (24) in which the flat carton group (b) is housed is connected to a pair of front and rear receiving plates (25) and (25) having substantially the same cross-sectional shape as the conveying air pipe (8). And a body portion (27) formed of a flexible guide body (26), and an accommodation opening (28) is formed above the accommodation opening (8a) of the transfer air pipe.

The receiving plates (25) (25) as described above are configured to be several m / m smaller than the diameter of the conveying air pipe, but they are designed to receive the air pressure, and the guide body (26) that is further flexible. Is to hold the carton, which bends to follow the bend of the pipe. Then, the spring (50) shown in FIG. 5 is embedded in the joint portion between the flexible guide body (26) and the receiving plate (25), and the receiving plate is normally biased in the left and right directions. When the flat carton group (b) is stored and discharged, the flat carton group (b) acts in the left-right opening direction, that is, in the loosening direction. It serves to hold down the carton group (b).

Now, when the flat carton group (b) is loaded into the capsule (24) from the supply magazine rack (21), the supply shutter (22) is closed. In this way solenoid valve (29a)
Air is supplied from an air inlet pipe (29) provided with, and the capsule (24) is conveyed in the pipe (8) by air pressure.

At the time of transportation, the capsule (24) carries the transportation air pipe (8).
It is guided by the guide rail (30) installed in the unit and moves.

Therefore, this guide rail (3
A projection (31) that fits in the groove (0) is provided on the lower part of the receiving plates (25) (25).

The guide rail (30) as described above allows the storage opening (28) of the capsule (24) to face upward at the front end of the pipe (8) (Fig. 5) and downward at the rear end (9th). As shown in the figure), it is installed in a shape that guides the capsules (2) that were in an upward posture when the flat cartons (b) were stored.
This is to make it easy to discharge flat cartons by taking a reversal posture when discharging 4).

In addition to the above, at the front end portion of the transfer air pipe (8) in the structure for supplying the transferred object, there is a shock absorber including a spring (32). This shock absorber controls the displacement of the solenoid valve (29a) and the cushion of the spring (32) so as to eliminate the impact of the empty capsule (24) conveyed from the discharge part. As it is composed of a weak magnet, it is designed to stop the empty capsule (24) in place.

In addition, if the size of the carton is changed, the storage capsule will be replaced. In that case, the size of the backing plate (25) does not change and the size of the body is different for the capsule that fits that size. To be

Then, the lid (33) at the end of the transport air pipe (8) is removed, the spring (32) is removed, the old capsule (24) is taken out, the new capsule (24) is inserted, and the spring (32) is again inserted.
It is used by inserting and sealing with the lid (33).

Next, a flat carton in units of groups, that is, a configuration for discharging a transported object will be described.

As shown in FIG. 9, a discharge port (34) is opened at the end of the transfer air pipe (8), and the discharge port (34) is sealed by a carton receiving plate (35).

And like the front end, there is a spring (36) as a carton shock absorber, and an exhaust pipe (3) equipped with a solenoid valve (38a).
There is 8).

Therefore, the flat carton group (b) stored in the capsule (24) is reversed by the capsule guide rail (30), and the shock of the stored capsule is adjusted by adjusting the exhaust of the spring (36) and the solenoid valve (38a) of the shock absorber. Is softened and stopped at a fixed position, that is, a position corresponding to the discharge port (34) by the magnetism of the spring (36) of the shock absorber.

When the capsule (24) stops, the spring (50) embedded in the joint between the receiving plate (25) of the capsule (24) and the flexible guide body (26) causes the air pipe (8) for transportation.
Since there is no air pressure inside, it works in the direction of loosening the backing plate (25) that was holding the flat carton group, that is, in the front-rear opening direction, eliminating the pressing of the flat carton group (b) The flat carton group (b) thus made falls from the capsule (24) to the carton receiving plate (35) by its own weight.

At the same time as the flat carton group (b) falls on the carton receiving plate (35), the carton receiving plate (35) descends from the position (B) shown in FIG. 10 to the position (C).

Then, at time (C), the carton pressing device (39) presses the flat carton group (b), and the carton receiving plate (35).
It descends to the position of (D) in synchronization with.

It goes without saying that the carton pressing device (39) is composed of a hydraulic cylinder and a pressing plate for its piston rod.

Then, at the same time when the carton receiving plate (35) arrives at the position (D), the carton pressing device (39) separates the flat carton group (b) and escapes from that position. At the same time, the carton push-out pusher (40) operates to push the flat carton group (b) into the guide bar (41).

As shown in FIG. 3, the guide bar (41) is a part of the carton magazine rack of the cartoner (42), and the flat carton group is directly supplied to the magazine rack.

At the outlet, when the capsule (24) comes to the outlet, the above operation is repeated and the flat carton group (b) is supplied to the magazine rack.
4) is transported toward the front end after the discharge port (34) is sealed by the carton receiving plate (35).

(Effect of the Invention) According to the present invention, since a capsule that is guided and reciprocates along the guide rail provided in the transport air pipe by air is provided in the transport air pipe, the capsule is guided along the guide rail. The object to be transported can be transported back and forth through the air pipe, and at the entrance of the transportation air pipe, a number of flat sheets such as flat cartons, etc., stored in a returnable box are erected in the horizontal direction. A suction head for stacking and aligning a group of objects to be conveyed, sandwiching the sheet-like bodies at both ends thereof, sucking the upper part of the objects to be collectively taken out from the carrying box, and transferred to the upper part of the entrance of the conveying air pipe. It is provided and further receives the transported objects from the suction head and sequentially loads them, and the loaded transported objects are loaded one by one from the lower one by their own weight. Since there is a magazine rack to supply to multiple boxes stored in a returnable box (for example, 2 for flat cartons)
(0 to 300 sheets) flat objects such as cartons are clamped from both ends in a batch state, and the upper part is sucked out and taken out.
This can be surely transferred to the supply magazine rack, and the transported objects accumulated here are sequentially fed into the capsule under its own weight while being kept in a batch state, so that it can be transferred as a plurality of transported objects. Can be done orderly.

Further, at the end of the transfer air pipe, the capsule is turned upside down by the guide rails so that the storage port of the capsule faces downward, so that the objects to be transferred are collectively collected at the outlet near the end of the transfer air pipe. In this state, it can be discharged to the transported object hopper by its own weight and can be supplied to the next process in an orderly manner.

According to this device, the transported object can be freely transported to the location of the next process in the complicated factory from the stock location of the transported object. It is not necessary to install it near the place, and the space in the factory can be used effectively.

In addition, once the objects to be conveyed are stocked in the supply magazine rack, it is possible to install a supply robot for each transfer line.
It is rational that one feeding robot can feed the objects to be transported to multiple transportation lines.
