Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying a material contained in a container to a subsequent process as a continuous stream of a constant quantity. For example, in the tobacco industry, shredded tobacco is stored in conveyor-type silos and supplied to the hoisting process, but instead of conveyor-type silos, shredded tobacco can be placed in a number of storage boxes and automatically and easily stored. In order to supply the shredded tobacco to the winding process as needed, a device is required to provide a continuous stream of shredded tobacco stored in each storage box.

The present invention provides a method for supplying batch-shaped materials, such as shredded tobacco, which have a large volume and are likely to scatter when turned over, to the next process as a continuous flow, by moving the storage box according to the turning operation. The purpose of this device is to provide a device that has a lifting plate that can be pushed down and is configured to open and close a damper of a dust removal duct in conjunction with the reversing operation, with less scattering of materials and lower running costs. is as defined in the claims at the front.

It is composed of a photoelectric detector 28 and a control circuit (not shown) provided to receive signals from the upper photoelectric detector 26 and lower photoelectric detector 27 and transmit driving and pole number switching signals to the motor 7. . The material product prevention plate 22 has a thickness of 0.5 mm to 1 in the case of shredded tobacco.
A plate with punched holes of mm diameter is suitable.

The lifting and lowering reversing unit A includes an arm lifter 30 having a lifting hydraulic cylinder 31 and an arm lifter 0.
an inversion table 33 rotatably supported by a shaft 32 provided at the top of the inversion table 33, and a reversal hydraulic cylinder 34 provided between the inversion table 33 and the arm lifter 30;
A large number of transfer rollers 35 are provided on the reversing table 33 in parallel with the pulleys 4-1 and 4-2.
, the transfer roller driving electric motor 36 provided on the reversing table 33, the chain sprocket 35-1 provided at one end of each transfer roller 35, and the tension between the chain sprocket 35-1 and the electric motor 36. The drive chain 37 and the reversing table 33 are provided with a lower end, and an upper end is provided on the transfer roller 35.
Two fork-shaped storage box holders 38 having a direction parallel to the transfer direction of It is composed of a clamp-shaped storage box holder 39.

The elevating and reversing section A is provided on the side of the material dispensing section B, and is configured so that the side portion 40-2 of the containing box 40 pushes down the elevating plate 18 when the containing box 40 is inverted. The damper 24 is opened and closed in conjunction with this reversing operation. A storage box conveyor (not shown) is provided on the floor so as to have the same conveyance surface as the transfer roller 35 when the arm lifter 30 of the up/down reversal unit A is at its lowest position. The storage box 40 used in the device of the present invention is a rectangular parallelepiped with an open top 40-1, and has four side parts 40-2 and a bottom 40-3, and the storage box holder 38 is inserted into the bottom 40-3. Two insertion ports 40-4 are provided for insertion.

The operation of the present invention will be explained below with reference to FIGS. 1 to 9.

The incoming storage box 40 is transported by the storage box conveyor, and the storage box holder 38 is inserted into the insertion opening 40-4 by the transport roller 35 driven by the electric motor 36, as shown in FIG. It is placed on the inversion table 33 in a state where the Furthermore, the storage box holder 39 is slid to fix the side portion. Next, as shown in FIG.
1 to the middle stage, and when the photoelectric detector 25 detects a decrease in the number of materials for a certain period of time, the reversing table 33 is reversed about the shaft 32 by the hydraulic cylinder 34 as shown in FIG. At the start of the reversing operation, the damper 24 is opened and air is sucked through the dust removal port 21, causing the material 4 to fly up into the air.
5 is attracted to the material product prevention plate 22 to prevent it from scattering. Side part 40-2 of storage box 40 due to reversal
hits the upper end of the elevating plate 18 and pushes it down. In this state, the storage box 40 is almost rolled over, and the materials 45 in the storage box 40 are fed into the material dispensing section B relatively quietly. Then the seventh
As shown in the figure, the arm lifter 30 is raised to the highest stage by the hydraulic cylinder 31 while the hydraulic cylinder 34 continues the reversing operation. At this time, the lifting plate 18 is moved to the storage box 4 by the weight 19.
It is increased as 0 increases. The angle of reversal is set to 125° or more in the case of shredded tobacco, preferably 135°. Due to this reversal, the material 45 in the storage box 40
is completely fed into the material dispensing section B. The damper 24 is closed after the reversal is completed.
As a result, the material adsorbed on the material prevention plate 22 of the dust removal port 21 falls onto the transfer conveyor 5. As shown in FIGS. 8 and 9, the empty storage box 40 is returned from the overturned state to the vertical state, and after being lowered, the holding of the storage box holder 39 is released, and the transport roller 35 sends it to the conveyor. It can be done.

Material 45 sent into material dispensing section B
is sent to the hopper 8 by the transfer conveyor 5 and the rotary rake 9, and sent out in fixed amounts from the take-out conveyor 11 to the next process. When the height of the material in the hopper 8 rises to the level of the upper photoelectric detector 26, the transfer conveyor 5 is stopped, and when it falls to the level of the lower photoelectric detector 27, the transfer conveyor 5 is driven at low speed by the electric motor 7. The height of the material on the exit end of the transfer conveyor 5 is detected by the photoelectric detector 2.
Below level 8, the transfer conveyor 5 is driven at high speed by the electric motor 7. Furthermore, the elevating plate 18
When the height of the material on the side becomes below the level of the photoelectric detector 25, the material 45 is fed from the lifting/lowering reversing section A.

As described above, the present invention reduces running costs with less scattering of materials when supplying batch-shaped materials that are bulky and prone to scattering when turned over to the next process as a continuous flow. This made it possible to provide the equipment.
