Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic cigarette supply device d that uses a tray containing cigarettes to supply cigarettes to a supply hopper on a cigarette packaging machine.

(Prior Art) Conventionally, a rotating body equipped with two symmetrical tray holding frames is installed near a supply hopper so as to be able to rotate intermittently through 180 degrees.
A transfer path '3 is provided on the side of the tray for intermittently transferring the tobacco storage trays at regular intervals, so that while the trays supported by one holding frame of the rotating body drop and feed the rolled cigarettes to the hopper, the other a device for returning an empty tray from a holding frame to a transfer path and transporting a new actual tray from the transfer path to the holding frame;
That is, a rotating body device with a double tray holding frame was seen (Japanese Patent Publication No. 58-5032).

(Problems to be Solved by the Invention) However, the above conventional device is a system in which the tray is taken in and out directly from the tray transfer path to the holding frame of the rotating body. It is a structure that is placed at a high place where it is located at the same location.

However, when using a transport vehicle that arranges and transports trays, the actual trays are moved on the floor and then lifted from the transport vehicle onto a high transport path to minimize the rotation radius of the rotating body. This necessitates work to remove the material, which causes a decrease in work efficiency.

Therefore, in order to enable the use of a transport vehicle together with the above-mentioned double type rotating body, it is being considered to interpose a lift mechanism that raises and lowers the tray between the transport vehicle and the tray holding frame of the rotary body. If a simple lift mechanism is used, the tray hoistway becomes one way, and it takes time to raise and lower the tray (tl return), which poses a problem in increasing the speed of the cigarette packaging machine.

Therefore, in view of the conventional circumstances, the present invention shortens the cycle time of the entire cigarette supply operation by using a double rotary body and a two-way lift mechanism between the rotary body and the transport vehicle. , automatic supply that can keep up with the speeding up of cigarette packaging machinesv
The purpose is to provide the t position.

After being carried into the tray holder (5b) (FIG. 20), it enters a standby state (FIG. 14), and the same operation is repeated thereafter.

In the above embodiment, the lift frame (△) has a small bevel gear (20) provided on the pulley shaft (19) that meshes with a fixed large bevel gear (22) so that the lifting power is taken from the planetary FA vehicle mechanism. Therefore, the power for turning and for lifting is provided in one system, and it can be combined with a light M and simple lift frame structure in which no lifting power is installed in the lift frame (△).

Also, the tray holding frame (8) of the rotating body (D)
In the inverted position where cigarettes are being supplied, when the remaining amount of cigarettes in the holding frame decreases to a predetermined amount, the lifting rod (35)
Or (35') moves the empty tray (a') upward by a predetermined distance (Fig. 12), so there is no interference between the upper end of the cigarettes supplied in the hopper (2) and the empty tray (a'). Rotating body (D) without fear? It is possible to do a half-turn, which can further shorten the tatami-nikuru time.

(Effects) According to the present invention, there is a rotary body that holds a tray that accommodates rolled cigarettes and changes it from an upright state to an inverted state, and a conveyance vehicle that places the tray with the foot gap MA and moves intermittently. Since a lift frame equipped with an elevating mechanism is interposed between the two, it is possible to reduce the radius of rotation of the rotating body, and the hand-held carrier can be used as it is as a transport vehicle, thereby simplifying the structure of the device.

The rotating body is equipped with two tray holding frames to create a double type, and in addition, the lift frame is equipped with two tray holders, which can be rotated and raised and lowered to create a two-way system for stomach descent. Therefore, the tray replacement time (recycling time) of the entire cigarette supplying operation can be shortened and the speed can be increased.

In addition, since the tray is rotated 180 degrees by the lift frame and then transported to the holding frame of the rotating body, the rotating body can be installed on the back side of the upper part of the hopper, and there are no obstacles in the front of the hopper, making maintenance and inspection work safe and easy. It's convenient.
