Description

[Detailed description of the invention] When a lid is welded and sealed to a pack filled with contents such as shredded kelp tsukudani, the extract of the tsukudani and debris from the contents adhere to the top flange of the pack. If this happens, the pack may not maintain its sealing properties, or a brown colored area may appear at the flange weld between the pack and the lid, resulting in loss of commercial value. This has traditionally been done manually.

The purpose of the present invention is to mechanize and automatically operate the wiping of the upper end flange of this pack.

In the present invention, a pack fitting hole 3 for engaging the upper end flange of the pack with the hole edge is bored in the conveyor 2 which is conveyed along the conveyor frame 1 intermittently at a constant pitch, and the conveyor frame 2 is positioned at a stop position. A lifting board 5 having a bottom surface on which a plurality of band-like cloths 4 that cooperate with each other to cover the upper surface of the pack fitted into the pack fitting hole constantly slides in tension in the longitudinal direction is moved up and down on the conveyor frame 1. Attach a restraining plate 7 that loosely fits into the pack at the stop position via the straightening plate part 6 passing between the adjacent band-like cloths 4, 4 on the underside of the elevator board, and when the transport frame 2 is stopped. The present invention is characterized in that a device is attached to the conveyor frame 1 to lower the elevator plate 5 until the cloth strip 4 comes into contact with the upper end flange of the pack.

An embodiment of the present invention will be described below with reference to the drawings.

The conveyor frame 2 is provided with two pack fitting holes 3, 3 symmetrically, and the endless conveyor chains 8 are attached to both sides of the conveyor frame 2. The guide rails 9 are attached to the inner side of the conveyor frame 1.
The conveyor frame attachment is sent to the left side of FIG. 1 along the pitch intermittently.

Reference numeral 10 denotes a rail-shaped receiving plate that faces the bottom surface of the packs 11 made of hard plastic sheets that are fitted into the pack fitting holes 3 with a small gap therebetween.

The lifting board 5 has guide shafts 1 fixed upright on the upper surfaces of both sides thereof.
2 is slidably penetrated through a base 13 installed between the conveyor frames 1 on both sides, and a vertical air cylinder device 14 installed between the base 13 and the elevator plate 5 allows the elevator plate to be moved as shown in FIG. The raised position and the cloth contact plate 15 fixed to its lower end
is raised and lowered between a lowered position where the belt-like cloth 4 is pressed against the pack upper end flange 11a on the transport frame.

Reference numeral 16 denotes brackets protruding and fixed to the front and rear sides of both sides of the base 13, respectively (front and rear brackets on each side). A swing frame 20 is rotatably supported, and a drive roller 21 in contact with the push roller 19 is fixed to a drive shaft 17.

In the illustrated case, the support shaft 22 of the push roller 19 is eccentrically supported by a circular bearing disc 20a fixed to the swing frame 20 so as to be rotatably adjustable, and the rotation of the circular bearing disc moves the push roller 19 to the drive roller. 21 can be opened and closed.

A chain wheel 24 is attached to one end of the right drive shaft 17 via a one-way clutch 23, as shown in FIG. A chain wheel 24 is attached thereto, and the both side chain wheels 24 are interlockingly connected to an output shaft 27 of a reversible motor and a speed reducer 26 mounted on the base 13 via a chain transmission mechanism 28, respectively.

Therefore, the chain wheels 24 on both sides are always driven in the same direction at a constant speed.

Reference numeral 29 denotes a transmission mounted on the base 13 via a support 29a, and the transmission 29 has drum support shafts on both sides that are always driven at a constant speed in the same direction (direction C) by a motor 30 mounted thereon. 31.

Each drum support shaft 31 supports two drums 3, respectively, as shown in FIG.
A friction clutch 34 is provided between the front and rear ends of the drum support shaft and each drum 32 and is actuated by a compression spring 33, respectively.

One end of the two strips of cloth 4, 4 sandwiching the plate adjustment portions 6, 6 on both sides is connected to the guide roller 18 and drive roller 21 of the right swing frame 20.
．． The band-like cloth passes successively between the push rollers 19 and is wound around the right drum 32, and the other end of the band-like cloth is wound around the guide roller 18 and drive roller 21 of the left swing frame 20. The band-like cloth 4 is wound around the left-hand drum 32 after passing between the push rollers 19 in sequence, but the way the band-like cloth 4 is applied to the left and right drive rollers 21 is symmetrical.

Further, compression springs 35 are installed between the lower part of each swing frame 20 and the base 13, so that the band-like cloth 4 is always maintained in a tensioned state regardless of whether the elevator plate 5 is raised or lowered.

Therefore, when the output shaft 27 is driven in the direction A in FIG. 2, the one-way clutch 23 of the right chain wheel 24 engages, driving the right drive roller 21 in the direction of the arrow in FIG. 3, and driving the left drive roller 21 in the same direction. The band-shaped cloth 4 is slid to the right along the bottom surface of the cloth sliding contact plate 15 of the elevator board 5 while being rotated.

In this case, the left drive roller 21 or shaft 17 rotates as a result of rotation.
Since the left chain wheel 24 driven by the output shaft 27 is rotating at a constant speed in the same direction (direction A), the left one-way clutch 25 does not engage, and therefore the left chain wheel 24
is idling.

The cloth strip 4 sent out from the right drive roller 21 is wound around the right drum 32, while the left drum 32 sends out the cloth strip while slipping with respect to its support shaft 31 at a friction clutch 34.

The rotational speed of the drum support shaft 31 should be considerably larger than the rotational speed of the drive roller 21 in order to absorb circumferential speed fluctuations due to changes in the outer diameter of the wound cloth.

In this way, when the left drum 32 completely unwinds the strip 4, the strip stops, so the ring 37 to which the detection arm 36, whose tip is always in contact with the outer periphery of the wound cloth of the drum 32, is fixed is rotated on the transmission 29. When the belt-like cloth 4 reaches a predetermined amount of winding, the protrusion of the shaft 37 activates the limit switch 38 (
A cloth winding amount detector is installed on the drum as appropriate, such as by activating the drum (Fig. 1), and the output shaft 2 is
7 is provided with a device for reversing the rotation.

When the output shaft 27 reversely rotates in the direction B, the one-way clutch 25 of the left chain wheel 24 engages and drives the left drive roller 21 in the same direction, so the band-like cloth 4 is rotated to the left while the right drive roller 21 is driven to rotate. The one-way clutch 23 of the right chain wheel is disengaged.

Therefore, since the band-like cloth 4 is always sliding under tension in the longitudinal direction along the bottom surface of the elevator board 5, the elevator board is lowered at the beginning of the stop of the conveyor or conveyor frame 2, and returned to the raised position at the end of the stop. By providing a device that controls the air cylinder device 14 in conjunction with the conveyor control device,
The pack fitted into the pack fitting hole 3 of the transport frame 2 passes through a press device 39 for compressing the contents of the pack and a sweeping device 40 that sweeps the contents attached on the top end flange 11a of the pack into the pack. 11 stops directly below the lift plate 5, the lift plate is automatically lowered by the air cylinder device 14, and the contents are held down by the restraining plate 7 so that they do not protrude onto the upper end flange 11a of the pack. The cloth 4 allows the user to try on the extract and the like deposited on the upper end flange.

As shown in FIGS. 4 and 5, the illustrated restraining plate 7 has a groove 7a into which a horizontal seat plate 6a fixed to the lower end of the straightening plate part 6 is relatively inserted.The lower surface of the plate 7b is made of stainless steel. A wire mesh 7C made of
The figure shows where it is detachably attached.

According to the present invention, since the contents of the pack are pressed down by the restraining plate 7 and do not come into contact with the band-like cloth 4, there is no fear that the contents will stick to the band-like cloth or that the band-like cloth will be soiled by the contents. Since the plurality of belt-like cloths 4 slide in and hold the fairing portion 6, there is no risk of leaving any residue on the upper end flange of the pack, which is actually quite effective.
