BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket returning device in a weight sorting device for fresh fish or the like.

[0002]

2. Description of the Related Art In a weight sorter of this type, a mounting member is attached to an endless chain as shown in Japanese Utility Model Laid-Open No. 57-9372, and a cup supporting device is connected to the mounting member via a parallel link. The cup (bucket) is mounted movably in the up and down direction, and a cup (bucket) on which a sorting target product is placed is mounted on a cup support device.

[0003] A pin which slides on a guide rail during traveling is provided at a lower portion of the cup supporting device. When the pin slides on the guide rail, the cup supporting device is moved to a raised position. , The cup runs in a horizontal position with the items to be sorted placed thereon.

[0004] At the discharge station having the same weight rank, the path of the guide rail is switched, the cup supporting device is lowered to the lowered position, and the cup is tilted to discharge the articles to be sorted.

In such a conventional apparatus, in the measuring section, the cup supporting device and the cup are lifted via the pins to measure the weight of the articles to be sorted, and the path of the guide rail is determined based on the measured value. It has been switched.

[0006] The guide rail switching mechanism is provided at each discharge position for each weight rank, and the cup that has been discharged by tilting the cup is returned to its original state before heading to the next discharge position. A return path inclined from the lower position to the upper position is provided in the guide rail switching mechanism.

[0007]

However, in such a configuration, the pins that slide on the guide rails during traveling run on the weighing rail in the weighing section and weigh. In other words, since the pins not only control the posture of the cup support device but also participate in weighing, the pins are deformed when used for a long period of time, and normal weighing is expected. There is a high possibility that it will not be possible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bucket return device in a weight sorting device having a simple structure that can maintain the reliability of weighing for a long period of time.

[0009]

According to the present invention, there is provided a bucket return device in a weight sorting device, comprising a plurality of bucket support frames erected on an annular transport chain orbiting in a horizontal plane, and a fixed side pivotally connected to the bucket support frame. A pair of upper and lower horizontal links that are supported and pivotally pivoted at the movable end thereof to the bucket support member and extend a part of the fixed side as a pressing portion to the opposite side to the movable end, A holding rail provided along the traveling path of the transport chain, wherein the pressing portion engages to hold the movable side of the horizontal link at the raised position, and the movable side of the horizontal link attached to the bucket support member is at the raised position. A tiltable bucket on which sorting objects are loaded in a certain state, and a trigger provided in the middle of the traveling path of the transport chain and capable of selectively releasing engagement between a pressing rail and the pressing portion. And the trigger is operated at the discharge station of the corresponding weight rank to release the engagement between the holding rail and the pressing portion, and the bucket is tilted to discharge the sorting object, and the tilting is performed. The sorting object is ejected and attached to the fixed side so as to abut against the bucket supporting member passing in the lowered position, and the lower side of the traveling path of the transport chain is raised so as to push the bucket supporting member in the lowered position to the raised position. And a bucket return ramp.

[0010]

According to this structure, the pressing portion of a part of the horizontal link extending to the side opposite to the movable side of the horizontal link to which the bucket support frame is attached is engaged with the holding rail to place the bucket in a horizontal posture. Hold and run. The weighing can be carried out by lifting the bucket supporting frame as in the prior art. At the discharge station of the weight rank at the corresponding position, the trigger is disengaged, the bucket support frame is lowered, and the bucket is tilted to discharge the items to be sorted. If the ejection station is not the ejection station of the weight rank at the corresponding position, the trigger does not come off, and the bucket travels in the horizontal posture while being guided by the holding rail toward the next ejection station.

When the bucket supporting frame in which the bucket descends and tilts arrives at the position where the bucket return ramp is provided,
The bucket supporting frame rides on the bucket return ramp and is pushed upward, so that the pressing portion of a part of the horizontal link is again engaged with the holding rail, and the bucket is returned to the horizontal posture and travels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. First, the basic structure will be described with reference to FIGS.

As shown in FIG. 5, a tare weighing station 1, a weighing station 2 and a discharge station 3 are arranged on the outer periphery of the apparatus, a control apparatus 4 is provided at the center of the apparatus, and an endless transport chain orbiting around the apparatus (shown in FIG. 5). Omitted)
A plurality of bucket support frames 5, and a plurality of buckets 6 on which sorting objects are placed
Is installed to be tiltable.

As shown in FIG. 4, the bucket supporting frame 5 is connected to a supporting column 8 erected on a transport chain 7 by vertically connecting a bucket supporting member 11 via two upper and lower horizontal links 9 and 10. The pressing portion 12 is provided at the rear end of the lower horizontal link 10, and the bucket 6 is pivotally attached to the upper end of the bucket support member 11 so as to be tiltable. This bucket 6
When the pressing portion 12 slides on the lower surface of the holding rail 13,
When the bucket supporting member 11 rises and holds a horizontal state, and the pressing portion 12 is released by the trigger 14 which is formed to be tiltable on a part of the holding rail 13 at the discharge station 3, the bucket supporting member 11 descends. To tilt.

As means for returning the tilted bucket 6 to the original state, the lower horizontal link 10
The pressing unit 12 is provided with an appropriate return device 15 and can be pushed down and slid into the lower surface of the pressing rail 13 by the returning device 15, but a separate power unit is required to press the pressing unit 12 down. In addition, since it is necessary to push down the pressing portion 12 that is moving together with the bucket support frame 5, a problem that the structure of the return device 15 becomes extremely complicated occurs.

In order to solve this problem, the embodiment is configured as shown in FIGS. 1 and 2 are a front view and a side view of the bucket support frame in which the bucket is tilted, and a right view of FIG. 1 and FIG. 3 are a front view and a side view of the bucket support frame in which the bucket has returned.

As shown in FIGS. 1 to 3, a plurality of bucket supporting frames 22 erected on a transport chain 21 circulating in a weight sorting device (see FIG. 5), and can be tilted on these bucket supporting frames 21. And a plurality of buckets 23 on which the sorting objects are mounted, and a bucket return slope 24 provided outside the transport chain 21 along a part thereof. A holding rail 25 is laid inside the transport chain 21, and a bucket tilting trigger 26 is formed on a part of the holding rail 25 at the discharge station (see FIG. 5) so as to be tiltable.

The bucket support frame 22 is provided with a transport chain 21.
A steel plate supporting member 30 having a U-shaped cross section is vertically connected to a pair of steel plate supporting columns 27 erected in the vertical direction via two upper and lower horizontal links 28 and 29. The bucket support member 30 pivotally attaches the bucket 23 via a support pin 31 provided at one upper end to the bucket 23 and supports the bottom surface of the bucket 23 via a rubber cushion 32 provided at the other upper end. To hold the bucket 23 in a horizontal state (see FIG. 3),
A guide roller 33 is provided at the lower end. The upper horizontal link 28 has rubber cushions 34 at both ends,
When tilted, it comes into contact with the bottom surface to keep the tilt angle within a predetermined range (see FIG. 2). The lower horizontal link 29 is provided with a pressing portion 35 at the rear end, and when the pressing portion 35 slides on the lower surface of the holding rail 25, the bucket support member 30 is raised to hold the bucket 23 in a horizontal state (see FIG. 3). ). Numeral 36 denotes a hook, which is engaged with the support pin 31 so as to be freely detachable, and prevents the bucket 23 from jumping up and coming off the bucket support member 30 due to an impact or the like when the sorting object is placed on the bucket 23. The ramp 24 has a short horizontal section at the top and is located on the exit side of the discharge station.

Next, the operation of the above configuration will be described.
The bucket supporting frame 22 having the sorting object placed on the horizontal bucket 23 moves to the discharge station after the weighing.
Specifically, in the tare measuring station 1 and the measuring station 2, the guide rollers 33 ride on the respective measuring rails, the bucket supporting member 30 is pushed upward, and the pressing portion 35 is separated from the guide rail 25 to perform accurate weighing. Is performed.

When reaching the discharge station of the corresponding weight rank, the trigger 26 provided at the position of the chute corresponding to the weighed weight is released, and the pressing portion of the lower horizontal link 29 is released.
Release 35. As a result, the bucket support member 30 descends, and the bucket 23 tilts to discharge the sorting target object onto the chute (see FIG. 2). The bucket supporting frame 22 that has discharged the sorting object moves to the ramp 24 while the bucket 23 is tilted.

In this case, the guide roller 33 of the bucket support member 30 climbs up the slope 24 with the movement of the bucket support frame 22, and raises the bucket support member 30 to raise the bucket 23 to a horizontal state. When the guide roller 33 reaches the horizontal portion on the top of the ramp 24, the bucket 23 returns to a completely horizontal state (see FIG. 1), and while the guide roller 33 passes through the horizontal portion, the pressing portion of the lower horizontal link 29 is pressed. 35 slides into the lower surface of the holding rail 25 again, and the bucket 23
(See FIG. 3).

As described above, the bucket return device according to the present invention has a very simple structure, and thus operates reliably. Furthermore, since the bucket 23 can be held and run in a horizontal position by the engagement between the pressing rail 25 and the pressing portion 35, the section where the guide roller 33 rides on the measuring rail and the ramp 24 on the ramp 24 at the time of weighing. Except for the state of the part, the guide roller 33 does not need to be in contact with any of them, so that the wear of the guide roller 33 can be reduced and accurate measurement can be performed for a long period of time.

[0023]

As described above, according to the present invention, when the tilted bucket 23 is returned to the original state, it is only necessary to use the movement of the bucket support frame 22 to climb the slope 24. Since no power unit is required, the structure is extremely simple and operation is ensured.

Further, since the bucket 23 can be run while being held in a horizontal posture by the engagement between the holding rail 25 and the pressing portion 35, the bucket supporting frame 22
The lower end of the bucket support frame 22 does not need to be in contact with any portion except for the section where the lower end of the bucket rides on the weighing rail and a part of the state where the lower end of the bucket rides on the ramp 24.
It is possible to reduce the wear on the lower end of the device and to perform accurate weighing over a long period of time.
