[Problem that the invention attempts to solve]

By the way, in the above-mentioned conventional packaging device, there is a risk that the enoki mushrooms etc. placed on the mounting member may float when the mounting member moves forward, so the upper surface side of the mounting member is placed on the lid body. I try to cover it up.

At this time, as shown in Japanese Patent Publication No. 53-38667, the lid is closed with an operating handle to keep the enoki mushrooms etc. stable, but since the operating handle is manually operated, it is a hassle. It requires a lot of work and is difficult to work with.

In addition, in the above-mentioned lid mechanism previously proposed by the applicant, the lid comes into contact with the expansion guide member and is closed as the placement member moves forward, so the expansion guide member It is easy for the load to be directly applied when the lid comes into contact with the bag, which places a burden on the support shaft that supports the expansion guide member so that it can be opened and closed, and as a result, affects the operation of the expansion guide member to expand and hold the mouth of the bag. There is a risk of it getting lost.

Furthermore, in each of the above-mentioned conventional devices, the placing member for supplying enoki mushrooms etc. into the bag and the expansion guide member for expanding and holding the mouth of the bag are each driven by a driving means. Because it is configured,
There are disadvantages in that the device tends to become complicated and tends to lead to higher costs.

This invention was made for the purpose of improving the problems of conventionally known packaging devices.

[Means for solving problems]

The mounting member can be moved forward and backward in the longitudinal direction from its rear position on the mounting member, and the mounting member has a pair of lid members that can be opened and closed with respect to the space above the mounting member on both sides of the mounting member in the longitudinal direction. Further, a closing guide member is provided on the forward side of the placing member to abut the lid member and urge it toward the closing side, and the above-mentioned placing member and/or This packaging device for mushrooms and similar products is characterized in that it is provided with an openable/closable expansion guide member that contacts the lid member and opens to the outside on both sides to expand the opening of the bag that has been set in advance. An expansion guide member for expanding and holding the bag is installed on the opening side of the bag without using a driving means to simplify the operating mechanism, and a lid member attached to the placement member is placed between the expansion guide member and the placement member. The purpose is to enable the closure in a stable state and to avoid applying a large load to the expansion guide member.

〔Example〕

Hereinafter, one embodiment of the invention of this application will be described in detail based on the accompanying drawings.

The frame 1 has opposing members 1a and 1b, and a pair of air cylinders 2 and 2a are cantilevered upward and downward along a perpendicular line to the member 1a, and the piston 3 of the cylinder 2 is connected to a bracket 4. be.

A substantially semicircular enoki mushroom mounting member 5 is cantilevered to the bracket 4 along the longitudinal axis of the piston 3.

A pair of parallel rails 6, 6a are installed on the opposing members 1a, 1b of the frame 1. A bracket 4 is inserted through these rails 6, 6a, and the piston 3 of the cylinder 2 is mounted together with the mounting member 5. It moves forward and backward as it moves.

The bracket 4 is provided with a cam 7, and a switch 8 is fixed to a part of the frame 1 and forms a control means, which corresponds to the cam 7 and operates in contact with the cam 7 when the bracket 4 moves backward. There is.

A pushing guide member 9 is attached to the piston 3a of the cylinder 2a and extends above the enoki mushroom mounting member 5 and along its longitudinal axis.

A guide rod 10 is attached to the push-in guide member 9, which extends above the piston 3a along its longitudinal axis and is pivotally supported by the opposing member 1a. stick 1
0 along the longitudinal axis of the enoki mushroom mounting member 5.

A cam 7a is attached to the guide rod 10 so as to be movable and adjustable along its longitudinal axis.
switch 8 which is actuated in contact with this by the forward movement of
a is fixed to the opposing member 1a of the frame 1 to form another control means.

The switches 8, 8a are designed to control the backward movement of the enoki mushroom mounting member 5 and the pushing guide rod 10, as will be described later.

A pair of left and right substantially arc-shaped lid members 11 are attached to the enoki mushroom mounting member 5 on both longitudinal edges thereof.
In this case, it is hinged and can be moved to the closing side or to the opening side with respect to the space above the mounting member 5.

A pair of blocking guide members 12, 12a each having a substantially U-shape are fixed to the opposing member 1b at one side thereof, and the other sides thereof are opposed to each other in a substantially V-shape, and the upper front end of each opposing side is diagonally The bending guide portions 13, 13a are bent inwardly toward the upper edge in the longitudinal direction.
When the enoki mushroom mounting member 5 moves forward, the lid member 11 closes the closing guide member 1 at its front end.
2 and 12a as well as the bending guide portions 13 and 13a to close the space above the enoki mushroom mounting member 5.

Bolts 14 and 14a are screwed through each of the opposing members 1b, and depending on the degree of screwing of these bolts 14 and 14a, the opposing sides of the closing guide members 12 and 12a can be pressed to adjust the opposing gap. This allows the degree of closure of the enoki mushroom placement member 5 by the lid member 11 to be adjusted.

The front side positions of the closing guide members 12, 12a are pivoted to the opposing member 1b, and springs 15, 1 are normally attached to the closing side.
A set of expansion guide members 16, 16a biased by 5a
are arranged, and the front ends of these guide members 16, 16a are
In this case, when it comes into contact with the front end of the lid member 11, it opens outward, and the opening of the polyethylene transparent bag 17, which is set and opened in advance on the front side, is further expanded.

The bags 17 are stacked, for example, in a container (not shown), and are transferred and supported one by one to a set position by suction means connected to a compressor, as is well known.

An opening guide member 18 is fixed to the opposing member 1a of the frame 1 and has its top on the longitudinal axis of the enoki mushroom mounting member 5 and tilts rearward. As a result, the rear end of the lid member 11 follows both inclined surfaces of the guide member 18, thereby opening the lid member 11 on both the left and right sides.
The initial state is maintained.

Of course, it is also possible to connect the enoki mushroom mounting member 5 and the lid member 11 with a spring (not shown), and use the elasticity of the spring to bias the lid member 11 against the mounting member 5 in the open state at all times. It is.

The operation of the above configuration will be explained.

Enoki mushrooms are introduced from a hopper (not shown) and are supported by a mounting member 5 having a substantially semicircular shape.

At this time, the pushing guide member 9 is located at the rear side of the enoki mushroom as an initial state.

From this state, for example, the motor is rotated, and the device is driven in a well-known manner by a series of sequences based on electrical signals by a control means consisting of a group of cams that respond to the motor, and a group of switches that contact and operate the motor. .

That is, in this case, first the cylinders 2, 2a
The pistons 3 and 3a move forward at the same time, and along with this, the enoki mushroom mounting member 5 starts moving forward along the rails 6 and 6a together with the bracket 4 connected thereto, and the pushing guide member 9 also moves forward along the guide rod 10. It moves forward with the movement.

Here, the speeds of the pistons 3 and 3a are set to be the same, so that the guide member 9 relative to the mounting member 5
The positional relationship remains unchanged.

As the forward movement of the enoki mushroom mounting member 5 progresses, the front end of the lid member 11 connected thereto comes into contact with the V-shaped closing guide members 12, 12a fixed to the facing member 1b of the frame 1, and the closing guide member 12,12
The lid member 11 is biased toward the closing side along the bending guide portions 13, 13a on the front upper edge of the lid member 11a.
When the front end of the lid member 11 passes between the closing guide members 12 and 12a, the entire lid member 11 closes the space above the enoki mushroom mounting member 5.

In this state, it is useful to prevent the enoki mushroom from coming off the mounting member 5, to prepare for the next operation, and to shape the posture of the enoki mushroom.

When the mounting member 5 moves forward further, its front end, together with the front end of the lid member 11 which is closed in this case, comes into contact with the expansion guide members 16, 16a located in front of the closure guide members 12, 12a, and presses them.

Therefore, the expansion guide members 16, 16a are connected to the spring 1
5, 15a and open outward against the elasticity of the bag 17, thereby penetrating into the mouth of the bag 17 set in advance as described above, expanding outward from the inside, and passing through the mouth of this bag 17. The placing member 5 enters into the bag 17 within a certain range together with the closing lid member 11.

In this state, the forward movement of the mounting member 5 is stopped.

In this embodiment, the above-mentioned state is set when the bracket 4 comes into contact with the opposing member 1b of the frame 1.

Of course, it is also possible to control by the operating stroke of the piston 3.

The forward motion of the piston 3a continues, and as a result, the pushing guide member 9 pushes the enoki mushroom on the mounting member 5 toward the inside of the bag 17 from the rear side, and this also stops within a certain range.

At this time, the guide rod 10 connected to the push-in guide member 9
When the cam 7a contacts the switch 8a, the piston 3 of the cylinder 2 starts to move backward, and the enoki mushroom mounting member 5 moves backward together with the lid member 11.

During the backward movement of the mounting member 5, the cover member 11 is forcibly opened by running along both inclined surfaces from the top of the opening guide member 18, and returns to the initial state.

At this time, the piston 3a of the cylinder 2a is in a stationary state, so that the enoki mushrooms are in the bag 17.
It is packed inside and sent to the next packaging stage.

During the backward movement of the enoki mushroom mounting member 5, when the bracket 4 connected thereto comes into contact with the switch 8, an electrical signal causes the piston 3 of the cylinder 2a to be activated.
a starts a backward movement, and as a result, the push-in guide member 9 moves backward and returns to the initial state.

In this embodiment, when the push-in guide member 9 is released from contact with the expansion guide members 16, 16a during the backward movement, the guide members 16, 16a are activated by the springs 15, 15a.
It closes due to its elasticity and returns to its initial state.

Therefore, according to the device of this invention, by placing the enoki mushrooms on the mounting member 5, it is possible to stuff the enoki mushrooms into the bag reliably and neatly without creating a complicated device structure, and the product can be packed. It has the advantage of increasing value.

Although an air cylinder is used in the embodiment of this invention, a hydraulic cylinder or the like may also be used.Although the case deals with bags of enoki mushrooms, other items to be packaged may also be used.

[Effect of idea]

The present invention connects one piston of a set of cylinders with a mounting member for mushrooms or similar materials so that they can move forward and backward, and connects a push-in guide member to the other piston so that they can be placed on the mounting member. The mounting member is capable of moving forward and backward in the longitudinal direction from its rear position, and the mounting member is provided with a pair of lid members that can be opened and closed with respect to the space above the mounting member on both sides of the mounting member in the longitudinal direction.
Furthermore, a closing guide member is disposed on the forward side of the placement member to abut the lid member and urge it toward the closing side, and the placement member and/or the placement member is placed in front of the closure guide member.
Alternatively, by providing an openable and closable expansion guide member that comes into contact with the lid member and opens on both sides to expand the opening of the bag that has been set in advance, the device structure can be simplified compared to the conventional one. The opening/closing operation of the lid member attached to the mounting member can be operated satisfactorily by the closing guide member, and the closing guide member does not apply an unreasonable load to the operation of the expansion guide member that can be opened and closed. Accordingly, it is possible to provide an inexpensive packaging device for mushrooms and similar products that is easy to maintain and manage.
