Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an inlet device for an empty can press machine that presses used empty cans one by one.

[Conventional technology]

Recently, there has been an extremely high demand for canned beverages such as youth and coffee, and in order to dispose of used empty cans, press machines are used to press empty cans one by one to reduce their volume. However, in many of the conventionally known empty can press machines, an opening/closing door that is normally closed is installed in the loading opening, which is sized to allow empty cans to be loaded one by one. A holding plate that can temporarily hold empty cans is attached as an integral part.
When the opening/closing door is closed, the holding plate opens and the empty can is dropped toward the press section, which then presses the empty can.

[Problem that the invention attempts to solve]

The above-mentioned conventional empty can press machine has an opening/closing door and a holding plate that are integrally formed, and the opening/closing door is normally closed by the opening/closing door. There are handling problems, such as a three-step operation including loading the empty can, which is extremely troublesome, and the opening/closing door cannot be closed completely. At this stage, it is possible to insert a hand or a piece of stick into the press section through the gap between the tilted holding plate and the machine body, so there is a risk of tampering with the machine body or injury. In addition, the force that pushes the opening/closing door in the closing direction directly acts on the holding plate, increasing the falling speed of the empty can. If an empty can suddenly falls toward the inside of the press section, the empty can may stand up and fall inside the press section, which subsequently affects the filling of the empty can. Therefore, the opening/closing door described above only impairs the operability of filling empty cans, and is not expected to be very effective in terms of safety measures.

[Means to solve the problem]

In view of the above-mentioned points, the present invention is intended to provide an inlet device for an empty can press machine that has excellent operability and safety for charging empty cans, and can have a structure as simple as possible. The purpose of this is to connect a machine with a slot above the press for empty cans into which empty cans can be inserted, and to install a top lid for opening and closing the slot and a top lid below the top lid. A lower lid is provided to temporarily hold the empty can, and the upper and lower lids are each placed under the action of a spring and supported rotatably, and support cams that can be joined to each other are fixed to both lids. The lower cover is normally held closed by the connection of both support cams to the upper cover which is normally held open, while the press plate reciprocates within the press section. A presser is provided to press the lower cover during the forward movement of the press plate, and an electric switch is arranged on the rotation path of the lower cover to turn on and start the press plate when the lower cover is opened. This is achieved by the constructed empty can press inlet device.

[Effect]

The opening and closing of the top and bottom lids can be regulated by spring action and the connection of support cams that can be joined freely.While the top lid is normally open, the bottom lid is kept closed, and the bottom lid is temporarily placed on top of the bottom lid. The empty can falls into the press section by the closing operation of the top cover, and is pressed by the forward movement of the press plate. Therefore, while the pressing operation continues, the lower lid can be kept closed regardless of the opening/closing operation of the upper lid, so that the empty can can be loaded safely and can be operated with one touch with one hand.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The input port 2 provided in the machine body 1 can be opened and closed by an upper lid 3, and a lower lid 4 is provided inside the machine body 1 with a gap between the upper lid 3 and the lower lid 4 to accommodate one empty can K.
is provided. Support cams 5 and 6 that can be joined to each other are fixed to the upper cover 3 and the lower cover 4, respectively, and the upper cover 3 and the lower cover 4 are attached to the fuselage 1 by the support shafts 7 and 8 of these support cams 5 and 6. It is pivoted. The lower lid 4 is provided with a back plate 4a that is sloped upward, and one support cam 6 is mounted on the back plate 4a.
is fixed. One end surfaces of the support cams 5, 6 are formed into arcuate cam surface portions 5a, 6a, and both support cams 5, 6 can be joined together by the cam surface portions 5a, 6a. The upper cover 3 and lower cover 4 are placed under spring action by coil springs 9 and 11, and the fuselage 1 is
The upper lid 3 is normally held open by a coil spring 9. On the other hand, the lower lid 4 is also urged in the opening direction by the coil spring 11, and as shown in FIG. Rotation of the lower cover 4 is prevented by bringing it into contact with the side surface of the support cam 6 that has been
When the upper lid 3 is open and not in operation, the lower lid 4 is kept closed. The machine body 1 is connected to a press section 13 of a press device body 12, and the press device body 12 is configured to move forward and backward with respect to a receiving plate 14 and a supporting plate 15 that are supported in a fixed state and the receiving plate 14. It has a set press plate 16 which is actuated by a piston rod 18 of an actuating cylinder 17. The press part 13 has a receiving plate 14 and a press plate 16
The press part 13 has a holding rod 19 protruding from the support plate 14, which is formed between the press plate 13 and the press plate 13, and has a size that can accommodate one empty can K dropped from the input port 2 in a sideways state. protrudes through 16,
This holding rod 19 is designed to temporarily hold an empty can K that has fallen into the press section 13. Further, a presser 21 that presses the lower cover 4 in the closing direction when the press plate 16 moves forward is fixed on the press plate 16 using means such as screws 22. The upper end portion 21a has a fourth
As shown in the figure, when the pusher 21 is in the forward position, it comes into contact with the lower surface of the lower cover 4 which has completed the closing operation, and prevents the lower cover 4 from opening. An operating rod 23a of an electric switch (for example, a micro switch) 23 is provided on the rotation path of the lower cover 4.
As shown in FIG. 2, the operating rod 23a is pressed and turned on by the lower cover 4, which operates to open as shown in FIG. . Note that one coil spring 9 is attached to the support cam 5.
The other coil spring 11 is connected between the protrusion 25 provided on the rear plate 4a and the fuselage 1, and between the rear plate 4a and the fixed frame 24.
The body 1 is provided with an escape hole 26 that allows the projection 25 to move. In the figure, 16a is a hole, and 27 is a screw hole drilled in the presser 21, which is formed in a long hole shape so that the vertical position can be adjusted. Also, 28 is the input port 2

[Effect of the idea]

The present invention is as described above, and the opening and closing operations of the upper and lower covers can be reliably regulated by the pair of support cams coming into contact with each other, and since the lower cover cannot be opened unless the upper cover is completely closed, it is possible to prevent hands from entering the press section. The danger of inserting a In addition, the expensive solenoid mechanism normally used in this type of device is no longer required as a means for locking the top or bottom lid, and the number of parts is reduced, resulting in a significantly simplified structure and a significant cost reduction. Furthermore, this inlet device can be assembled into a single independent unit by incorporating all the main parts into the machine, making it very convenient to assemble with a press machine, and is both economical and safe. Coupled with its superior properties, its practical value is extremely great.
