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 conventional empty can press machines are equipped with an opening/closing door at the input opening to prevent injuries caused by inserting one's hand into the press 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 for the input opening is provided, the empty cans are 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 machine and has safety measures to completely prevent hands from being inserted into the machine body through the input port.

That is, an 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 insert a sleeve for loading empty cans between this window hole and the press section of the press device body. The input sleeve is rotatably provided, and the input sleeve is placed under the action of a return spring so that the input sleeve is normally held in an inclined state located in the window hole. A lid body and an actuation rod capable of freely locking the lid body are attached, and the discharge port is normally closed by the action of a spring that returns the lid body and the action of locking the actuation rod against the lid body. The actuating rod is held in position and is placed under the action of a traction spring that biases the actuating rod in the direction of disengaging it from the lid, and the above-mentioned actuation is continued until the loading sleeve is rotated and placed in the upright position. a guide portion that restricts the axial movement of the rod; an engaging portion located at the terminal end of the guide portion that allows the actuating rod to move in the axial direction and is capable of locking the actuating rod; and the loading sleeve. a start switch for the press device body that is turned on when the press plate is placed in an upright position, and a position in the press device body that closes the discharge port of the input sleeve in synchronization with the forward movement of the press plate. an inlet for an empty can press machine, comprising: an actuator for moving the lid body; and a release element that operates when the press plate returns to the starting position to release the actuating rod from its engagement portion; This is accomplished by a device, and examples thereof will be described below with reference to the accompanying drawings.

A press device body 3 for empty cans K is housed inside the machine body 1, which has a window hole 2 in the upper part of the front surface, and this press device body 3 is formed between a front plate (receiving plate) 4 and a rear plate 5. The press plate 6 is provided with a press plate 6 that moves forward and backward in the pressed press part 3a, and a drop port 8 for the pressed empty can K is provided between the bottom part 7 and the front plate 4. The piston rod 9a of the operating cylinder 9 is connected to the press plate 6, and the empty can K dropped onto the bottom 7 can be pressed by the forward movement of the press plate 6.

A charging sleeve 11 is rotatably provided between the window hole 2 and the press part 3a, and 12 is its pivot, and this pivot 12 is attached to a fixed frame 13. The sleeve 11 is placed under the action of a return spring 14 so that the sleeve 11 can maintain an inclined state with its input port 11a side normally positioned in the window hole 2.
When the sleeve 1 is rotated and stands upright, the discharge port 11b of the sleeve 11 is configured to face directly above the press section 3a. The return spring 14 is the sleeve 1
It is hung between a protrusion 15 provided on 1 and a fixed frame 13. Further, support ring parts 16 and 17 are fixed on the back surface of the sleeve 11 at upper and lower positions along the axial direction of the sleeve 11, and the support ring parts 1
An actuating rod 18 placed under the action of a traction spring 19 is slidably supported by the actuating rods 6 and 17.
The upper end 18a is always in contact with the lower surface of the rotator 22 which is pivotally mounted 21 on the upper support ring 16 by means of a traction spring 19, and the lower end 18b can freely protrude downward from the surface of the discharge port 11b of the sleeve 11. A trochanter for an engaging member is rotatably attached to the rotor 22.

A lid body 24 for opening and closing the discharge port 11b is pivotally attached to the sleeve 11 by a support arm 25, and the lid body 24 has an arcuate cross section and a return spring 2.
6, and the support arm 25 is supported on the pivot 12. A stepped locking part 24a is formed on the lid body 24, and the lower end 18b of the actuating rod 18 can be freely locked therein.
The cam 27 is attached to the left end (in the figure), and the cam 27 is attached to the other end (the tip of the part extending from the locking part 24a).
A slightly raised locking piece 28 is provided, and
A locking spring 29 for temporary locking is provided at the end portion of the movement path of the cam 27 (for example, the portion on the front plate 4 of the press device body 3). However, the return spring 2
6 is a protrusion 31 provided on the support arm 25 and the fixed frame 1
3, and the support arm 2
5 is provided with a pin-shaped engager 32 that can be pressed freely by an actuator (described later) provided on the press plate 6 side of the press device body 3.

On the other hand, a rail-shaped guide part 33 is provided from the inside upper part of the window hole 2 toward the inside of the fuselage 1, and this guide part 33 is curved in an arc shape centered on the aforementioned pivot 12, and its length is While the sleeve 11 rotates and changes from an inclined state to an upright state, the trochanter 23 pressed by the operating rod 18 is dimensioned so as to be able to contact and roll, and the trochanter 23 can be freely locked at the end portion thereof.
and an engaging portion 3 that allows axial movement of the actuating rod 18.
4.

The engaging portion 34 has a lever-shaped release element 3.
The base of the release element 35 is pivotally attached 36 to the fixed frame 13 side, and in the illustrated case is operated in relation to a solenoid 37. A lever 38a for operating the start switch 38 of the press device body 3 is in contact with the upper surface of the release element 35, and the start switch 38 can be turned on by pushing up the release element 35.

That is, when the trochanter 23 is disengaged from the guide portion 33 due to the rotation of the sleeve 11 and moves upward at the same time as it locks into the engaging portion 34, the release element 35 is pushed up by the trochanter 23 and operates the lever 38a. Then, the press device body 3 can be started by turning on the start switch 38. In this case, the actuating rod 18 also rises and is released from the lid body 24. Also,
A micro switch 39 is provided at the position where the press plate 6 of the press device body 3 is retracted, and this micro switch 39 is turned on when the press plate 6 returns to the non-operating position, and operates the solenoid 37 to release the switch. The child 35 is pushed up, the trochanter 23 is disengaged from the engagement portion, and the return action of the sleeve 11 by the return spring 14 is enabled. On the other hand, on the press plate 6 is an actuator 41 that can press the engager 32 on the lid body 24 side.
is provided, and when the press plate 6 starts moving forward, the lid body 24 can be rotated in synchronization with this forward movement.

In addition, as shown in FIG.
2 is brought into contact with a stopper 43 fixed to the fixed frame 13, so that the inclined state of the sleeve 11 can be reliably maintained upon return. Also,
It goes without saying that the means for operating the release element 35, the means for operating the start switch 38, etc. are not limited to the illustrated embodiment; for example, it is of course possible to use mechanical means instead of the solenoid 37 to return the release element 35. It is. In the figure, 44 is a stopper provided on the operating rod 18, and 45 is an operating arm attached to the press plate 6. This operating arm 45 is used to operate the micro switch 39.

Next, to explain the operation of this inlet device, as shown in FIG. 3A, the outlet 11b is connected to the lid 24
There is an empty can K in the sleeve 11 which is closed by
When the sleeve 11 is rotated in the direction of the arrow to stand upright as shown in FIG. is allowed, and at the same time as the actuating rod 18 is moved, the actuating rod 18 is engaged with the engaging portion 34 via the trochanter 23, and the sleeve 11 is held in an upright state. On the other hand, the lid body 24 is disengaged from the operating rod 18 and returned to its original position by the return spring 26, so that the empty can K in the sleeve 11 falls into the press section 3a. Further, the release element 35 is raised by the trochanter 23, and the start switch 38 is turned on. After a preset time (3 to 5 seconds) has elapsed by turning on the start switch 38, the press unit 3 is activated and the press operation for the empty can K is started. When the press plate 6 moves forward at the start of this press operation, the lid body 24 is rotated in synchronization with the press plate 6, and closes the discharge port 11b of the sleeve 11 which is placed in an upright position as shown in FIG. 3D. At the same time, the cam 27 engages the locking spring 29 and the sleeve 1.
1, and the lid 24 is temporarily held in its closed position.

When the pressing operation is completed and the press plate 6 returns to the non-operating position, the trochanter 23 is pressed downward by the release element 35 as described above, and the engaging portion 3
4 and return to the guide portion 33, and the return spring 14 allows the sleeve 11 to return to its original inclined state. On the other hand, the lid body 24
is also freed and returns following the return movement of the sleeve 11, and all operating members are placed in a position to receive the next empty can as shown in FIG. 3F. The reason why the return movement of the cover body 24 is temporarily restricted by the locking action of the cam 27 when the press plate 6 retreats is that the cover body 24 rotates ahead of the sleeve 11 as the press plate 6 moves backward. This is to prevent the lower end 18b of the actuating rod 18 from getting caught on the 24 when the sleeve 11 returns to its rotation, thereby preventing the sleeve 11 from being able to return. The reason why the locking piece 28 is provided on the lid 24 is to prevent the lid 24 from being improperly rotated by inserting a hand or the like into the sleeve 11. In this case, the lid 24 is not locked. The stop piece 28 is the actuating rod 1
It can only rotate within a small range until it comes into contact with the lower end 18b of 8. Note that if a temporary release means for the actuating rod 18 and the lid body 24 is devised separately, the cam 27 can be attached to the lid body 24.
It is not necessary to provide

The present invention is as described above, and since the input port is always fully open, unlike conventional devices in which the opening/closing door is opened to input empty cans, the operation of loading empty cans is extremely easy. Of course, since the charging sleeve is placed in an inclined state, even if there is any leftover drink in the empty can, there is no need to worry about it spilling out and staining the hands and clothes of the user.

In addition, when the input sleeve rotates to the upright position and the input sleeve is securely locked in the upright position, the ejection port is released, and the human hand is moved to the machine as the input sleeve continues to rotate. Since the empty can cannot be inserted into the charging sleeve, there is no risk of the hand of the person charging the empty can being inserted into the press section, which has the advantage of being very safe in use. Coupled with its ease of operation, its practical value is extremely great.
