Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a packaging device for saws and similar products, and more particularly to an improvement in a bag opening pressing mechanism of the packaging device.

[Prior art and its problems] This type of packaging device generally charges pre-weighed mushrooms or similar materials from a hopper and places them on a supply member that is movable forward and backward under the hopper. The supply member is inserted into a bag made of polyethylene or the like, whose opening is supported in front of the supply member and whose opening is adjusted by a bag mouth presser, and when the supply member is retracted, the supply member is inserted into the bag made of polyethylene or the like. The mushrooms and other similar materials are stored in the bag by the pushing member located above, and the bag containing the mushrooms and other similar materials is dropped onto the conveying member and moved, and the air inside the bag is removed by gentle pressure. Then, after sealing the opening of the bag, the bag is transported out.

By the way, Japanese Utility Model Publication No. 56-5523 by the same applicant has been proposed as #j1 structure in which the bag opening is adjusted by presser inside the bag opening.

This is a bag opening presser in which a pair of rotating plates are pivotally supported in a V-shaped plane on a base plate, and an elastic force is applied to the tips of the rotating plates by a bullet so as to constantly close the tips of the rotating plates. It is arranged so that it can move forward and backward by the operation of a cylinder. However, such a design requires a separate and expensive cylinder assembly and also requires a control circuit to electrically time the operation of the supply member.

It is pivotal to 2. The upper end of the link arm 22 is loosely inserted into a receiving frame 28 at the tip of a guide rod 27 provided on the upper part of the opposing member 1a so as to be movable back and forth in the same direction as the rail 11, and a roller 29 pivotally supported by the receiving frame 28. It is formed so that it is guided by.

A connecting plate 30 is provided horizontally at the rear end of the guide rod 10, and the guide rod 21 is loosely inserted into the connecting plate 30. The rear end of the guide rod 27 is provided with an engaging protrusion 31 for engaging with the connecting plate 30, and the leading end thereof is provided with an engaging protrusion 33 for engaging with the receiving portion 32 of the guide rod 27 provided on the opposing member 1a. .

34 is a spring for pulling the link arm 22 forward.

By introducing enoki mushrooms from a hopper (not shown), the enoki mushrooms are supported by a substantially semicircular mounting member 5a that constitutes a part of the supply member 5. At this time, the pushing member 9
is initially located on the back side of the enoki mushroom. From this state, for example, the motor is rotated, and the motor is driven in a well-known manner by a series of sequences based on electric signals by a control means consisting of a group of cams that respond to the rotation of the motor, and a group of switches that operate in contact with the motor. That is, the pistons 3 and 3a of the cylinders 2 and 2a move forward at the same time, and the enoki mushroom mounting member 5a, which forms part of the supply member 5, moves along the rail 6.6a together with the bracket 4 connected thereto. When the pushing member 9 moves forward together with the guide rod 10 as shown in FIG. When the base 12 and the bag opening presser plate 13° 138 move forward and the rotating piece 17 is pushed by a predetermined width, the rotating piece 17 comes off the end of the receiving plate 16 and reverses, so it is no longer engaged with the pressing plate 20. The bag opening presser A consisting of the base 12 and the bag opening presser plate 13.13a is inserted into the mouth of the bag 35 and stopped. In this case, the link arm 22 connected to the base 12 by the connecting rod 24 swings forward about the pivot shaft 23 at the lower end together with the tensile force of the spring 34, and the engaging protrusion 33
is locked to the receiving part 32. As the enoki mushroom supplying member 5 advances further, the front end of the moss member 5b connected thereto comes into contact with a pair of V-shaped flat bag-mouth presser plates 13.13a disposed on the base 12. The lid member 5b is urged toward the closing side while following the inner surface, and thereby the lid member 5b closes the space above the enoki mushroom mounting member 5.

When the supplying member 5 moves forward further, the front end of the placing member 5b and the bag opening presser plate 13.13a move into the magazine 15.15.
It is released outward against the elasticity of the bag 35, expands outward from the inside while deeply entering the mouth of the bag 35, and is shaped into a substantially cylindrical shape through the bag mouth presser A at the mouth of the bag 35. The supplied supply member 5 enters into the bag 35 within a certain range. piston 3
The forward movement of step a continues, and as a result, the pushing member 9 presses the enoki mushrooms on the mounting member 5 from the rear side into the bag 35, and stops within a certain range.

Ru. Cam 7 of guide rod 10 continuous with this sharpening pushing member 9
When a contacts the switch 8a, the piston 3 of the cylinder 2 starts to move backward due to the electric signal, and the supply member 5 moves backward. During this backward movement of the supply member 5, the lid member 5b runs along the bag mouth presser plate 13, 13a and is forcibly opened, returning 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 stuffed into the bag 35 and sent to the next packaging stage. Next, when the pushing member 9 returns, the connecting plate 30 fixed to the rear end of the guide rod 10 engages with the engagement protrusion 31 of the guide rod 27 and is pushed backward by the connecting plate 30, as shown in FIG. Therefore, the guide rod 27 is moved rearward and connected to the guide rod 27, and the IC link arm 2 is connected to the guide rod 27.
2 swings rearward around a pivot 23 at the lower end, whereby the bag opening presser A, which consists of the base 12 and the bag opening presser plate 13.13a connected by the link arm 22 and the connecting rod 24, moves rearward. The rotating piece 17 connected to the base 12 by the connecting rod 18 returns to rotation.

In this way, as the supply member 5 moves forward, the bag opening presser A moves forward due to the engagement between the press plate 21 and the rotating piece 17, and the bag 3
The bag supplying member 5 is inserted into the bag 35 in a state in which it has surely entered the mouth of the bag 35, and the engagement of the connecting plates 1 to 'lO and the engaging protrusion 31 prevents the pushing member 9 from retreating. Presser foot A returns automatically.

In the above-mentioned embodiment, the forward movement of the bag opening presser A is connected to the feeding member 5, and the backward movement is connected to the pushing member 9, respectively. It may be connected so as to be interlocked with the supply member 5, or both the forward and backward movements of the bag mouth presser A may be connected so as to be interlocked with the supply member 5, or both the forward and backward movement of the bag mouth internal presser A may be connected so as to be interlocked with the supply member 5. It may be connected so as to be interlocked with the pushing member 9.

[Effects of the Invention] The present invention provides a bag in which a bag is placed in front of a supply member on which mushrooms or similar materials are placed and a pushing member located on the supply member, and the mouth of the bag is supported from the inside. A mouth presser is provided between the supply member and the mouth of the bag, the supply member and the pushing member are inserted into the bag via the bag mouth presser, and the push member is positioned on the supply member when the supply member is retracted. In a bag in which mushrooms or similar materials are stored in a bag, the bag opening presser is connected to the supplying member or the pushing member and is movable back and forth toward the mouth of the bag. Since the forward and backward movement of the presser foot can be performed accurately by a relatively inexpensive mechanism, mushrooms and similar materials can be stored in the bag reliably, which is highly effective.
