Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a connecting device for drawing and connecting containers in a compactor.

(Prior art) Generally, a container is unloaded onto the floor in front of the compactor's ejection port by a transport vehicle, and the container must be moved and connected so that the container's ejection port and the compactor's ejection port are precisely aligned. There is.
As an example of such a container connection device, a forward claw and a backward claw are rotatably provided inside a groove formed on the front floor of the compactor, and a lower part of a container carried above the groove is attached. There was one in which the respective claws were rotated and brought into contact with the stopper to draw the container toward or away from the compactor (see Japanese Patent Publication No. 26909/1983). However, since this configuration requires grooves to be formed in the floor surface, it is difficult to install it in existing buildings.To solve this problem, a cylindrical body installed at the bottom of the compactor that can be moved in the front and rear directions is used. A hook is pivotally supported at the tip of the container, and the hook is engaged with an engaging pin at the bottom of the container carried in front of the compactor, and the cylinder is moved to draw the container toward or away from the compactor, and to move the hook to the floor. There is a device that is brought into contact with a guide member provided on a surface and released from an engaging pin (see Japanese Patent Publication No. 54-23754).

(Problem to be Solved by the Invention) However, with the above configuration, when the hook is disengaged from the engagement pin, the cylinder cannot be moved backward until after the container is carried out, and the cylinder cannot be moved back before the container is carried out. If the compactor is moved backward, there is a problem that the hooks will engage with the engagement pins again.Furthermore, a trolley is provided in front of the compactor and the container is placed on the trolley.
This method could not be used when the container was moved by moving the cart. Further, when a guide device is provided for rotating the hook in the releasing direction, there is a problem that when the hook is held in the engagement position and the disengagement position, dirt and the like may enter the device and cause malfunction.

(Means for Solving the Problems) In view of the above problems, the present invention provides an input port at the top,
In a compactor having an extrusion port to which a container is connected at the front part and a pushing means inside, the compactor is provided with a boom movable in the front and back direction, and the boom is pivoted at the tip thereof so as to be swingable up and down. An engaging means consisting of an engaging member and a bullet provided between the engaging member and the boom and capable of engaging with the container is provided, and the engaging member is held upwardly inside the boom. The present invention relates to a container connecting device for a compactor, characterized in that it is provided with an operating means that is engaged during forward movement and disengaged during downward swinging operation and is disengaged during backward movement.

(Function) The function of the present invention with the above configuration is that, first, when a container and a compactor are connected, the boom is moved forward by the operation of the operating means, and the engaging member pivotally supported at the tip of the boom is activated by the biasing force of the bomb. is securely engaged with the container. On the other hand, when separating a container from a compactor, the boom is brought into contact with the container by moving forward, the container is moved and separated, and then the boom is moved backward while the engaging member is swung downward. It is something that makes you

(Example) Hereinafter, the configuration of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, 1 is a compactor with an input port 2 at the top and an extrusion port 3 at the front.

Next, the operation of the connecting device 10 will be explained based on the electric circuit 31 shown in FIG. First, when connecting the container 7 unloaded onto the trolley 6 to the compactor 1, the boom 13 is in the most retracted position, and in this state, the first limit switch LS1 is turned OFF and shut off, and the second limit switch LS1 is turned OFF.
The limit switch LS2 is turned ON and shut off, and when the operation switch PB1 of the connection operation circuit 32 is turned on,
Relay R1 is energized and its a contact is closed,
The extension solenoid SOL2 of the operating circuit 34 is energized, the switching valve V is switched to the left, and the cylinder 17
extends, and the boom 13 moves forward. that time,
Since the solenoid SOL1 is demagnetized, the arm 21 is in a horizontal state, and the engagement pin 22 is in the beam 1
3 moves forward, the hook 14 of the container 7
It comes into contact with the guide surface 14b of the hook 14, rotates downward against the bullet 19, and engages with the hook 14a of the hook 14.
When the boom 13 moves to the most forward position, the actuator 26 of the first limit switch LS1 is inserted into the recess 27 and turned ON, relay R2 is energized, its a contact is closed, its b contact is closed, and the extension solenoid is turned on. SOL2 is demagnetizing, contraction solenoid SOL3
is energized, the switching valve V switches to the right, the cylinder 17 contracts, the boom 13 moves backward, the container 7 is drawn to and connected to the compactor 1, and the boom 13 moves to the most retracted position. Second
Limit switch LS2 turns ON, and relay R1
is interrupted and the boom 13 stops.

Next, the connected container 7 is transferred to the compactor 1.
In order to separate the valve further, when the operation switch PB2 of the withdrawal operation circuit 33 is turned on, the relay R3 is energized and its a contact is turned on, the extension solenoid SOL2 of the operation circuit 34 is energized, and the switching valve V is switched to the left. As a result, the cylinder 17 extends and the boom 1
3 moves forward, cushion 29 stops at stopper 30
The container 7 is separated by contacting with the container 7. When the boom 13 moves to the most forward position, the first limit switch LS1 is turned ON in the same way as described above, and the relay R
4 is energized, its a contact is closed, and its b contact is cut off, at the same time the timer T starts operating. When the relay R4 is energized, the solenoid SOL1 is energized, the iron piece 24 is retracted, and the arm 21 is
9, and the engagement pin 22 is released from the hook 14. The timer T operates after the rotation time of the arm 21 has elapsed, its a contact is closed, its b contact is cut off, the extension solenoid SOL2 is demagnetized, the contraction solenoid SOL3 is energized, and the switching valve V is switched to the right. , the cylinder 17 contracts, the boom 13 moves backward with the tip of the arm 21 in the lowered state (disengaged state), and when the boom 13 moves to the most retracted position, the second limit switch LS2 is activated.
turns on, relay R3 is cut off, and boom 1
3 stops, the solenoid SOL1 is demagnetized, the iron piece 24 protrudes, and the arm 21 returns to the horizontal state (engaged state).

(Effects of the Invention) As described above, according to the container connection device in the compactor of the present invention, the engaging means capable of engaging with the container is provided at the tip of the boom that is provided in the compactor and is movable in the front-rear direction. Since the operating means for engaging the engaging means when the boom moves forward and disengages when the boom moves backward is provided inside the boom, installation is easy, and the engagement means can be engaged after the container is separated from the compactor and before the container is taken out. Since the parts can be moved backwards, a trolley on which multiple containers can be placed can be installed in front of the compactor, and the trolley can be moved to sequentially load garbage into the containers, allowing the compactor to operate more efficiently. be able to. Furthermore, since the operating means is provided inside the boom, even if dust or the like falls onto the boom, malfunctions will not occur due to the influence, and the boom will operate reliably.
