FIG. 10 is an enlarged front view of the swing chute shown in FIG.
FIG. 11 is an enlarged view of a portion X in FIG.
12 is a view taken along line XI-XI in FIG.

In FIG. 8, the container transport line 30 according to the conventional container discharge device 21 includes a box-shaped or bag-shaped container P carried out from the upstream-side container processing device 11 and four rows of upstream-side transport means 12A, 12B, 12C. , 12D is conveyed in the direction of arrow F1 and delivered to the container discharge device 21.
The container discharge device 21 is delivered to swing chutes 25A, 25B, 25C, 25D installed in series at positions corresponding to the upstream conveying means 12A, 12B, 12C, 12D above the downstream conveyor 10, The swing chutes 25A, 25B, 25C, and 25D are slid down and discharged onto the downstream conveyor 10 by swinging as shown by a two-dot chain line in FIG. After being transported on the conveyor 10 in the direction of arrow F2 and subjected to container processing by the downstream side container processing apparatus 13 of the container transport line 30, it is transported in the direction of arrow F3.

  As shown in FIG. 10, the swing chute 25A has a chute 26 integral with the shaft 27 driven by a driving device (not shown) on the basis of a command from the control device 29 and swings the shaft 27. As shown by the dotted line, the container P on the swing chute 25A is slid down in the direction of the two-dot chain line in the figure, and the swing chutes 25B, 25C, and 25D are the same as the swing chute 25A. It has a configuration.

Next, the operation of the conventional container discharge device 21 will be described with reference to FIGS.
The containers P on the swing chutes 25A, 25B, 25C, and 25D shown in FIG. 11 swing downward as shown in the figure based on the command from the control device 29, thereby causing the swing chutes 25A, 25B, 25C, and 25D. The upper container P slides all at once like the two-dot chain line shown in the figure, and only the locus Pf of the two-dot chain line shown in the figure (in FIG. 11, only the locus Pf in the case of the container P on the swing chute 25A is shown. The same applies to the swing chutes 25B, 25C, and 25D).
In addition, the container discharged | emitted on the conveyor 10 is illustrated with the symbol of the container P21, the container P22, the container P23, and the container P24, respectively for convenience of explanation.
Thereafter, the container P is delivered from the upstream onto the swing chutes 25A, 25B, 25C, 25D, and thereafter, the operation described above is repeated at a predetermined timing.

  In the conventional container discharge device 21 described above, the containers P21, P22, P23, and P24 conveyed on the conveyor 10 in the direction of the arrow F2 are slipped down as shown in FIG. When the container is tilted from the pre-sliding container posture and is carried into the downstream container processing apparatus 13 in the inclined attitude, there is a possibility that the downstream container processing apparatus 13 has a problem in the container processing.

  In addition, the swing chutes 25A, 25B, 25C, and 25D swing all at once, and the discharged containers P21, P22, P23, and P24 are sequentially transported on the conveyor 10 at an equal pitch. Is small, the container processing in the downstream side container processing apparatus 13 must be performed in a short time, and the container processing capacity may be insufficient depending on the shape, weight, and the like of the container. If the container P discharged above remains in the inclined posture, the container processing capability in the downstream container processing apparatus 13 may be further insufficient.

  In the present invention, in view of the above-described circumstances, a container delivered to a plurality of swing chutes installed in series is slid down and discharged to a downstream conveyor by a downward swing of the swing chutes. When the conveyor is transported by a conveyor, the container on the conveyor is placed on the swing chute so that it can be automatically corrected even if the transport posture is tilted due to sliding down, and the downstream container capacity can be accommodated. It is an object of the present invention to provide a container discharge device that can be conveyed at a larger pitch that is wider than the container pitch before sliding down.

The present invention solves the above problems by the following means.
According to the first aspect of the present invention, the container discharge device includes a conveyor that conveys the containers, and a plurality of swing chutes that are arranged in series in the conveying direction of the conveyor above the conveyor and that can swing in the vertical direction. A plurality of swing chutes attached to the bottom of each swing chute and a control device for controlling the swing of the swing chutes, wherein the swing chutes are moved from their original positions according to instructions from the control device. When swinging downward, the container on the swing chute previously delivered from the upstream slides down from the swing chute onto the conveyor and is discharged downward while being transported on the conveyor. By tilting the swing chute on the downstream side of the swing state, the inclination of the transport posture of the container is corrected. Configured to.

  According to another aspect of the present invention, in the container discharge device, the container comes into contact with the downstream side of the swing chute on the most downstream side in the transport direction in the closed state according to a command from the control device. An open / close stopper is provided to correct the inclination of the transport posture of the container being transported.

  According to another aspect of the present invention, in the container discharge device, the openable stopper has a configuration similar to that of the swing chute with the hook attached.

  According to another aspect of the present invention, in the container discharge device, after the plurality of swing chutes that have been delivered from the upstream in advance are swung every other or every predetermined number, the next is not yet performed. The control device is configured to alternately and sequentially swing the swing chutes of the swing every other or a predetermined number.

  According to another aspect of the present invention, in the container discharge device, the control device is configured such that the time during which the swing chute is swinging downward can be changed.

  According to another aspect of the present invention, in the container discharge device, the sliding direction of the container from the swing chute is the conveying direction of the conveyor.

  According to another aspect of the present invention, in the container discharge device, the control device is configured to start swinging of the plurality of swing chutes to be swung at the same timing.

  According to another aspect of the present invention, in the container discharge device, the control device is configured to start swinging of the plurality of swing chutes to be swung at a predetermined time difference timing.

  The container discharge device according to the above aspect of the present invention includes a plurality of swing chutes that are arranged in series in the conveying direction of the conveyor above the conveyor that conveys the containers, and a swing that is attached with a basket at the bottom. By using the chute, the container on the swing chute previously delivered from the upstream slides down from the swing chute by the swing and is discharged and conveyed on the conveyor. However, the inclination of the conveying posture can be automatically corrected by abutting against the heel already swung downward.

An open / close stopper that corrects the inclination of the transport posture of the container that is transported from the upstream side in contact with the container in the closed state by the command from the control device downstream of the swing chute on the most downstream side in the transport direction The container that slides down from the swing chute by the swing and is discharged and transported from the upstream side without correcting the inclination of the transport posture also hits the open / close stopper already closed downward. The inclination of the transport posture can be automatically corrected by touching.
Furthermore, the opening / closing stopper has the same structure as that of the swing chute attached with the hook, so that it can be opened / closed by the same swing control with the same structure as the swing chute delivered to the container. In addition, there is an effect that the opening / closing control can be shared.

  Further, when the plurality of swing chutes are swung at the same time, the containers on the swing chutes are slid down to the conveyor by the swing, and the discharged containers are delivered from the upstream in advance by the conveyor before the slid. The plurality of swing chutes are conveyed at the same pitch as the pitch corresponding to the interval between the containers on the plurality of swing chutes. After swinging every number, the next unswinged swing chute is swung alternately every other time, such as every other swing or every predetermined number, so that the containers slid down on the conveyor and discharged Since it is transported at a large pitch that is wider than the pitch corresponding to the container interval before sliding down, Responding to the downstream side container capacity by type of container can have a margin on the side of the container capacity can be flexibly.

  Alternatively, it is possible to change the transport pitch of the containers that have been slid down on the conveyor and controlled by changing the time during which the swing chute is swinging downward. The downstream container processing capacity can be given a margin, and the response to the downstream container processing capacity depending on the type of container can be made flexibly.

  Further, by controlling the swing of the swing target swing chute to start at the same timing or to start at a predetermined time difference timing, the response to the downstream side container processing capacity is further increased. be able to.

Note that the state of FIG. 5D is the same as the state of FIG. 4A, and the above description is repeated thereafter.

In FIG. 4B, the swing chute 5A, the swing chute 5C and the open / close stopper 5H swing from the original position of the two-dot chain line to the swing state of the solid line in the direction of the solid arrow, Each of the containers P on the swing chute 5A and the swing chute 5C slides down like a two-dot chain line in the figure and is discharged onto the conveyor 10 along a locus Pf of the two-dot chain line in the figure.
In addition, the container P discharged | emitted on the conveyor 10 is illustrated with the symbol of the container P11 and the container P13, respectively for convenience of explanation.
Here, the conveyance posture of the containers P11 and P13 discharged onto the conveyor 10 may be inclined from the container posture before sliding down.

  In FIG. 4C, the container P11 and the container P13 whose transport posture on the conveyor 10 is inclined (one example of the state where the transport posture is tilted are shown by a two-dot chain line in FIG. 6 for convenience of explanation). In contact with the hook 8 attached to the lower part of each of the swing chutes 5A, 5B, 5C, 5D of the swing chute 5C and the open / close type stopper 5H that have already swung downward when being conveyed downstream, As shown by a solid line in FIG. 6, the inclination of the conveying posture is corrected while sliding on the conveyor 10.

  In FIG. 4D, the swing chute 5A, the swing chute 5C, and the open / close stopper 5H are returned to their original positions from the swing state as indicated by the solid line arrows, and the containers P11 and containers on the conveyor 10 are returned. P13 is conveyed downstream with the inclination of the conveying posture corrected.

In FIG. 5A, the swing chute 5B, the swing chute 5D, and the open / close stopper 5H swing downward from the original position of the two-dot chain line to the swing position of the solid line in the direction of the solid line, Each container P on the swing chute 5B and the swing chute 5D shown in the two-dot chain line in the drawing slides down like the two-dot chain line in the drawing and is discharged onto the conveyor 10 along the locus Pf in the two-dot chain line shown.

Here, the transport posture of the containers P12 and P14 discharged onto the conveyor 10 may be inclined from the container posture before sliding down as in the case of the containers P11 and P13. When the container P14 is tilted, the container P14 comes into contact with the flange 8 of the open / close stopper 5H that has already been swung when the container P14 is conveyed downstream, and the inclination of the conveying posture is corrected while sliding on the conveyor 10.

In FIG. 5 (b), the swing chute 5B and the open / close stopper 5H swing back upward in the direction indicated by the solid line arrow to the original position shown by the solid line in the figure, and the container P12 whose conveying posture is inclined is located downstream. When it is transported to the side, it contacts with the flange 8 of the swing chute 5D already swinging, and the inclination of the transport posture is corrected while sliding on the conveyor 10.
The container P14 is transported downstream while the inclination of the transport posture is corrected.

In FIG. 5C, the swing chute 5D is returned from the swing state to the original position in the direction of the solid line arrow, and the container P12 and the container P14 on the conveyor 10 have the inclination of the conveyance posture corrected. It is conveyed downstream as it is.
In addition, illustration of the container P13 is abbreviate | omitted in FIG.5 (c).

5D, the swing chute 5A, the swing chute 5B, the swing chute 5C, the swing chute 5D, and the open / close stopper 5H remain in their original positions shown by the solid lines in the figure, and the containers P12, P14, and P11 and container P13 are transported further downstream while the inclination of the transport posture is corrected. In addition, illustration of the container P11 and the container P13 is abbreviate | omitted in FIG.5 (d).
In FIG. 5D, the container P is transferred from the upstream conveying means 12A, 12B, 12C, 12D onto the swing chutes 5A, 5B, 5C, 5D.

  Thus, the state of FIG. 5 (d) is the same as the state of FIG. 4 (a), and the container P delivered to the swing chutes 5A, 5B, 5C, and 5D is the same as described above. When the swinging shoot 5A, swing chute 5B, swing chute 5C, and swing chute 5D are slid down and discharged onto the conveyor 10 and the transport posture is tilted in the same manner as described above. Then, by abutting against the swing chute that has already been swung or the flange 8 of the open / close stopper, the inclination of the conveying posture is corrected and conveyed to the downstream side.

In addition, each swing chute or the swinging operation of the open / close type stopper and the swing operation to the original upper position in FIGS. 4 (a) to 5 (d) described above are performed by a command from the control device 9. .
As described above, the containers P that have been slid down by the swing of each swing chute and discharged onto the conveyor 10 can be simplified by coming into contact with the already swung swing chute on the downstream side or the hook 8 attached to the open / close stopper. The inclination of the transport posture can be automatically corrected with a simple device.

  For the containers P delivered onto the swing chutes 5A, 5B, 5C, and 5D, first the swing chutes 5A and one swing chute 5C are swung, and the containers P on the swing chutes 5A and 5C are placed on the conveyor 10. Then, after a predetermined time has elapsed, the swing chute 5B and one swing chute 5D are swung and the containers P on the swing chute 5B and 5D slide down onto the conveyor 10 to be discharged. The containers P are conveyed on the conveyor 10 at a pitch twice the pitch wider than the pitch corresponding to the container spacing on the swing chutes 5A, 5B, 5C, and 5D that has been delivered from the upstream in advance. Therefore, the container processing in the downstream side container processing apparatus 13 has a margin, and reliable container processing is performed on the downstream side according to the type of the container. It is possible.

  In addition, by controlling the swing chutes 5A and 5C and the swing chutes 5B and 5D to be in a swinging state downward, it is controlled so as to be changed to be longer or shorter, so that the double transfer on the conveyor 10 is performed. The pitch can be further increased or shortened, and accordingly, the container processing capacity of the downstream container processing apparatus 13 can be appropriately handled, and the response to the downstream container processing capacity depending on the type of container can be changed flexibly. it can.

  Furthermore, by setting the swings of the swing chutes 5A, 5B, 5C, and 5D at the same time every other piece, the twice transport pitch on the conveyor 10 can be kept constant. By setting a predetermined time difference timing for every other piece, the double conveying pitch on the conveyor 10 can be made larger or smaller than twice, and the downstream side container processing device 13 depends on the type of the container P. It is possible to appropriately correspond to the container processing capacity of the container, and it is possible to provide a wider range of correspondence to the downstream container processing capacity depending on the type of the container P.

In the above description, for convenience of explanation, the swing chutes for delivering the container P are illustrated and described for the case of four swing chutes 5A to 5D, but the number of swing chutes for delivering the container P is limited to four. Instead, six or other numbers may be used.
In addition, although the illustration and description of alternately swinging every other swing chute are shown, the swing chutes may be swung every two or even more than one.

  In the above description, the opening / closing stopper 5H has been described as having the same structure as the swing chutes 5A to 5D and the same swing control, but other forms of opening / closing movement in the direction of the arrow 18F as shown in FIG. Of course, as the structure of the open / close stopper 18 (corresponding to the rod 8), the opening / closing of the open / close stopper 18 may be operated by an actuator (not shown) under the control of the control device 9.
