Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inlet device suitable for implementation in an empty can press machine that presses used empty cans one by one to reduce their volume.

Many of the conventionally known empty can press machines are equipped with an opening/closing door at the input opening to prevent accidents such as injury caused by inserting one's hand into the press section inside the machine from the input opening. When loading empty cans, it is necessary to open the opening/closing door, which is surprisingly troublesome from the point of view of the person loading the empty can. In addition, in conventional empty can press machines, in order to quickly press loaded empty cans, the distance between the input opening and the press section is very short, and even if an opening/closing door is provided at the input opening, the empty can can be pressed when the empty can is opened. There is a risk of injury from inserting one's hand into the press section through the mouth, and the opening/closing door only makes it difficult to insert empty cans into the press, and is not sufficiently effective as a safety measure. Furthermore,
Press machines that place empty cans sideways into the slot have a problem in that if there is any leftover drink in the empty can, it will flow out when the can is loaded and stain hands, clothes, etc.

Therefore, the present invention was made in order to solve the above problems all at once.The purpose of the present invention is to keep the inlet open at all times, to make it extremely easy to empty the empty can, and to prevent the leftover drinks from flowing out. To provide an input port device for an empty can press machine which can be loaded into the press and is equipped with safety measures to completely prevent hands from being inserted into the press section through the input port.

That is, the object of the present invention is to provide a window hole in the upper front of a machine body in which a press device body for empty cans is installed, and to provide two semi-cylindrical bodies each having a bottom plate above the press portion of the press device body. A charging sleeve with a two-part structure that can be freely opened and closed is arranged by connecting the back side of the shaft with a pivot, and the inner end of the pivot is attached to a rotatably supported support, and the charging sleeve is The input port side is normally placed under the action of a return spring so as to maintain the inclined state located in the window hole, and the bottom plate of both the semi-cylindrical bodies is aligned with the bottom plate when the two semi-cylindrical bodies are closed. A locking hole is provided in each of the locking holes, and a lock pin that can be freely engaged in both of the locking holes is slidably attached to the support body, and the action of a spring biases the lock pin in a direction in which the lock pin is removed from the locking hole. a guide part that prevents the lock pin from moving in the axial direction until the input sleeve rotates and is placed in a horizontal state, and a locking part that temporarily locks the lock pin that has come off the guide part. and a return lever for removing the lock pin from this locking portion, and a start switch on the press device side that turns on to start the press device when the loading sleeve is placed in a horizontal state, and a press switch. An actuating body that moves in synchronization with the press plate of the device body, a pressing body that is actuated by the actuating body to press the two semi-cylindrical bodies in a closing direction, and a pressing body that moves toward the lock pin when the press plate retreats. This is achieved by an inlet device for an empty can press machine which is provided with an actuator for pressing the return lever, and an embodiment thereof will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a machine body, and a window hole 1a is opened at the upper part of the front surface, and a press device body 2 for empty cans K is housed inside the window hole 1a. The press device body 2 includes a press plate 5 that moves forward and backward within a press part 2a formed between a front plate (receiving plate) 3 and a rear plate 4, and a press plate 5 is provided between the bottom part 6 and the front plate 3. Drop port 7 for empty can K
A piston rod 8a of an operating cylinder 8 is connected to the press plate 5, so that an empty can K dropped into the press section 2a can be pressed. The front plate 3 and the rear plate 4 are connected by a pair of left and right connecting rods 9a, and a bridge plate 9b is installed between the left and right corners of the upper edge.

Above the press part 2a, a charging sleeve 11 formed in a size capable of accommodating one empty can K is rotatably provided.
As shown in the figure, two semi-cylindrical bodies 12 are butted against each other to form a two-part structure that can be opened and closed. That is,
Both half-cylindrical bodies 12 are provided with a bottom plate 12a, and can be opened and closed from each other by loosely inserting pivots 14 into ears 13 provided on opposite side edges. A locking hole 15 is provided that fits when the cylindrical body 12 is closed, and a locking piece for locking a return spring, which will be described later, is protruding from the peripheral surface.

A blinding plate 46 is provided on the a side, and this blinding plate 46 eliminates the problem of the window hole 1a being opened when the input sleeve 11 is rotated, and allowing a hand or the like to be improperly inserted into the machine body 1. Preventing danger. Note that it is also possible to provide an actuator 43 that presses the pressing piece 32 on the actuating body 42 side.
In the figure, 47 is a positioning stopper fitted onto the pivot shaft 14, and 48 is a limit switch.

Next, to explain the operation of this inlet device, an empty can K is introduced into the inlet sleeve 11 placed under the condition shown in FIG. Rotate it downward. When the charging sleeve 11 is placed in a horizontal position by this operation, the base 2 of the lock pin 25
5b comes off from the guide part 27 and becomes free, and the spring 2
6, the lock pin 25 is removed from the locking hole 15. This detachment operation of the lock pin causes the loading sleeve 1 to close.
1 (that is, the double-half-cylindrical state 12) is opened by the action of the return spring 24, and the empty can K falls into the press section 2a (see FIG. 6 A to B).

On the other hand, the return lever 29 is tilted backward by the ejecting action of the lock pin 25, and this action turns on the start switch 35, and after a preset time (3
5 seconds), the press device body 2 is activated. When the press plate 5 of the press device body 2 moves forward, the pressing body 36 is pressed by the operating body 42 and rotates, pressing both half-cylindrical bodies 12 and closing the charging sleeve 11 (sixth
(See Figures H-D). In addition, the lock pin 25 mentioned above
is temporarily locked on the locking part 28, and the charging sleeve 1
1 will be placed in a horizontal state.

When the press operation for the empty can K is completed and the press plate 5 moves to the backward operation and the press piece 32 is pressed by the actuator 43, the return lever 29 rotates forward in the opposite direction, and the lock pin 25 is rotated. Press. Due to this pressing action, the lock pin 25 moves forward against the spring 26 and engages both engagement holes 15, and at the same time, its base portion 25b is placed in a state where it can move into the guide portion 27. Next, when the pressure of the pressing body 36 against both half-cylindrical bodies 12 is released, the charging sleeve 1
1 can be returned to the original closing position by a return spring 24 in the closed state.

The present invention is as described above, and since the input port is always open, unlike the conventional device in which the opening/closing door is opened to input the empty can, the operation of loading the empty can is very easy. Of course, since the loading sleeve is placed in an inclined position with the loading port side facing upward, empty cans can be tilted vertically and loaded into the loading sleeve, and even if there is any leftover drink in the empty can being loaded. There is also no need to worry about spillage and soiling the hands or clothes of the user during the injection process. In addition, since the loading sleeve has a two-part structure that locks and simultaneously opens when it is rotated and placed in a horizontal position, there is no risk of a hand being inserted into the machine or the press section through the loading sleeve. There is no such problem and press work can be carried out safely. However, if a blind plate is provided to cover the window hole when the loading sleeve is in operation, it will be completely impossible to insert one's hand into the body of the machine, which has the advantage of further improving safety. Coupled with the ease of operation, which allows one-handed loading of the can and actuation of the loading sleeve, its practical value is extremely great.
