Japanese Patent No. 3130819 (FIGS. 1 and 3) Japanese Patent No. 4067425 (FIG. 1)

However, since the conventional article sorting and unloading device described in Patent Document 1 has a structure in which a shock absorber is provided in the housing portion itself to receive the dropped article, the difference in height at which the article slides down and falls is large. There was a problem that it was difficult to moderate the impact sufficiently.
Further, the conventional article sorting and unloading device described in Patent Document 2 has a structure in which the article is decelerated or temporarily stopped with the swinging bottom plate in a horizontal state on the downhill path, so that the configuration is complicated. there were.

  Therefore, the present invention solves the problems of the prior art as described above, that is, the object of the present invention is a simple configuration even when the difference in height at which an article slides down is large. It is an object to provide an article sorting / unloading apparatus that can sufficiently reduce the impact of a dropped article.

  The invention according to the first aspect of the present invention is based on a fixed chute that is an article delivery direction by appropriately sorting articles placed on a tray that runs along the transfer line into fixed chutes provided on at least one of the left and right sides of the transfer line. In the article sorting / unloading apparatus for sending to an accommodating portion provided on the conveyance carriage obliquely below, one end side of the article sending direction is fixed to the fixed chute and the other of the article sending direction is slackened in the article sending direction. By providing a sheet-like chute that is engaged on the opposite side to the fixed chute side of the transport carriage, the above-mentioned problem is solved.

  In the invention according to claim 2, in addition to the configuration of the article sorting and carrying out apparatus according to claim 1, the hook receiver on the other end side of the sheet-like chute is on the side opposite to the fixed chute side of the transport carriage. By being provided so as to be able to engage with the provided first hook, the above-described problems are further solved.

  In the invention according to claim 3, in addition to the configuration of the article sorting and unloading apparatus according to claim 2, the second hook that can be engaged with the hook receiver is formed from the lower end of the bottom plate on the fixed chute side with respect to the transport carriage. By being disposed above, the above-described problems are further solved.

  In addition to the configuration of the article sorting and unloading device according to any one of claims 1 to 3, the invention according to claim 4 is in contact with the fixed chute side of the transport cart to position the transport cart. A positioning member to be determined is disposed on a fixed chute side with respect to the conveyance carriage, and the positioning member is arranged in a direction in which the conveyance carriage and the fixed chute that are located at a predetermined position when the sheet-like chute is used are opposed to each other. By providing the position adjustable in the direction of the horizontal component, the above-described problems are further solved.

The invention according to the first aspect of the present invention is based on a fixed chute that is an article delivery direction by appropriately sorting articles placed on a tray that runs along the transfer line into fixed chutes provided on at least one of the left and right sides of the transfer line. In the article sorting and unloading device for sending to an accommodating part provided in the obliquely lower conveyance carriage, one end side in the article delivery direction is fixed to the fixed chute and the other end side in the article delivery direction is loosened in the article delivery direction. Since the sheet-like chute that is engaged with the opposite side of the fixed chute is provided with a sheet-like chute deformed and received by the slacked article, or the article delivered from the fixed chute is sheet-like The sheet-like chute is bent at the place where it comes into contact with the chute, and the sheet-like chute is bent at other places. As the article slides down and the kinetic energy of the article is consumed by the deformation resistance of the sheet-like chute and the frictional resistance between the article and the sheet-like chute, when the article reaches the accommodation unit of the transport carriage The impact can be sufficiently reduced with a simple configuration.
Furthermore, since the position where the article is stopped on the sheet-like chute is above the bottom in the accommodating portion of the conveyance carriage, the article is lowered downward only by releasing the engagement between the other end of the sheet-like chute and the conveyance carriage. It can be placed in the accommodating part of the transport carriage.

  In the article sorting and unloading apparatus according to the second aspect of the invention, in addition to the effect of the article sorting and unloading apparatus according to the first aspect, the hook receiver on the other end side of the sheet-like chute is opposite to the fixed chute side of the transport carriage. Since the hook receiver and the first hook can be easily engaged and disengaged by being freely engageable with the first hook provided on the side, the sheet chute and the transport carriage can be easily engaged with each other. Switching between connection and disconnection can be performed.

In the article sorting and unloading device according to the third aspect of the invention, in addition to the effect exhibited by the article sorting and unloading device according to the second aspect, the second hook that can be engaged with the hook receiver is a bottom plate on the fixed chute side with respect to the carriage. Since the hook receiver and the second hook are easily engaged and disengaged by being disposed above the lower end of the hook, the hook receiver is engaged with the second hook when the sheet-like chute is not used. By combining them, the sheet-like chute can be easily stored.
Further, when the sheet-like chute is not used, the position of the other end of the sheet-like chute is higher than the lower end of the fixed chute, so even if an article is accidentally sent from the fixed chute for some reason, the sheet The chute can receive the article and prevent the article from being damaged.

The article sorting and unloading apparatus according to the fourth aspect of the present invention, in addition to the effect produced by the article sorting and unloading apparatus according to any one of the first to third aspects, is brought into contact with the fixed chute side of the conveying carriage. A positioning member for determining the position of the carriage is disposed on the fixed chute side with respect to the conveyance carriage, and the positioning member is located in a direction in which the conveyance carriage and the fixed chute are located at a predetermined position when the sheet-like chute is used. Since the position of the positioning member can be adjusted in the direction of the horizontal component of the directions in which the conveyance carriage and the fixed chute face each other, the conveyance carriage in use can be adjusted. Can be adjusted in the direction of the horizontal component.
For example, since the lowest point of the loose sheet-like chute approaches the fixed chute by bringing the predetermined position of the transport carriage in use closer to the fixed chute, the articles sent from the fixed chute fall on the loose sheet-like chute Can be adjusted to.
On the other hand, by moving the predetermined position of the transport carriage at the time of use away from the fixed chute, the lowest point of the loose sheet chute is also moved away from the fixed chute so that the articles sent from the fixed chute slide down the sheet chute. Can be adjusted.
In addition, since the positioning member contacts the fixed chute side of the conveyance carriage, the article delivered from the fixed chute falls onto the loose sheet chute and the conveyance carriage is fixed when the loose sheet chute is tight. Even when a force to move the chute is generated, the transport carriage can be stabilized at a predetermined position.
