Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a tray stopper in a packaging device, particularly positioning when a boat-shaped tray with chamfered two ends of a quadrangle is transferred to a conveyor in different directions. The present invention relates to a tray stopper suitable for.

2. Description of the Related Art Conventionally, a tray 1'for storing food has been used in a quadrangular shape as shown in FIGS. Therefore, when the food 2 such as bread is placed on the tray 1 ′ and supplied to the packaging device 3, the transport device 4 of the tray 1 ′ is the entrance conveyor 5 ′ to the packaging device 3.
Even when the tray 1'is connected at a right angle, the positioning stopper 6 of the tray 1'can be accurately positioned as shown in FIG. 9 by providing a flat plate-shaped stopper 6 longer than the length of the tray 1 '. The tray 1 ′ positioned by the stopper 6 was scraped out by a chain blade 9 attached at a predetermined interval to a chain 8 stretched between the sprockets 7 and 7 ′ and conveyed to the packaging device 3.

Problems to be Solved by the Invention When the stopper 6 shown in FIG. 12 is used when moving from the transfer device 4 to the inlet conveyor 5 ', the oblique side 11 of the tray 1'is used.
When they contacted each other, they were balanced and the tray 1 '(Fig. 12) was held in this position. After that, when the tray 1'is conveyed by the chain blade 9 of the entrance conveyor 5 ', the tray 1'collides with the guide plates 12 provided on the left and right, and the tray 1'and the food 2 placed on the tray 1'are damaged. Will end up. In this case, it is necessary to stop the packaging device 3 once, remove the tray 1 ', and then restart the packaging device 3, which also reduces the movement rate of the packaging device 3.

Means for Solving the Problems The present invention is directed to a transport conveyor for transporting a substantially boat-shaped tray having a hypotenuse portion, and a tray for transporting the tray from the transport conveyor which is arranged orthogonal to the transport conveyor. A packaging apparatus having an inlet conveyor for transporting toward the packaging apparatus, wherein the conveyor has a guide plate for correcting the posture of the tray, and the inlet conveyor transfers the tray from the conveyor. At the position where the tray is received, and at the position corresponding to the received tray, there is a blade that conveys the tray toward the packaging device. It has a first stopper at a position where the hypotenuse portion contacts, and a second stopper at a position where it contacts the horizontal portion of the tray. Characterize.

By the first stopper that comes into contact with the oblique side of the tray, the tray is always positioned in the horizontal state, and the tray can be transported reliably.

EXAMPLE A tray 1 made of a synthetic resin such as styrene has chamfered two corners of a quadrilateral end 13 to form a unequal-sided hexagon having a hypotenuse 11 to form a substantially boat shape 14. Reference numeral 15 is a horizontal portion that is continuous with the hypotenuse portion 11, and five confectionery items such as foods 2 and bread are placed in the tray 1. The tray 1 on which foods 2 such as confectionery and bread is arranged is a sprocket 7 of an inlet conveyor 5 of a packaging device 3 which intersects the conveyor 10 at a right angle,
It is scraped out by a chain blade 9 attached to a chain 8 stretched between 7'and transferred to the packaging device 3 by an inlet conveyor 5 and supplied to the packaging device 3 to supply the food 2
The bread and sweets that are are packaged.

Guide plates 16 and 16 'for guiding the tray 1 are provided on the conveyor 10 of the embodiment of the present invention.
8'is guided in the direction of the arrow. At this time, the tray 1 located at the leading edge of the transport conveyor 10
Are positioned by a first stopper 17 and a second stopper 17 'in order to change the transfer direction to the packaging device 3. Further, the first stopper 17 is made of a plate-shaped body having a width narrower than the length of the tray 1, and is disposed at a position where the central region of the oblique side portion 11 of the tray 1 transferred by the transport conveyor 10 comes into contact with the second stopper. 17 'is arranged so that the horizontal portion 15 of the tray 1 is in contact therewith, and also serves as a guide plate when the chain blade 9 of the inlet conveyor 5 sends the tray 1 toward the packaging device 3 in the direction of the arrow.

The first stopper 17 and the second stopper 17 'are arranged in parallel with each other so as to be offset from each other in the front-rear direction, and are brought into contact with each other while the tray 1 is positioned at a predetermined position, so that the tray 1 is positioned stably.

Effect of the Invention As described above, when the present invention is applied to a packaging apparatus for packaging articles placed on a tray having a substantially boat shape, the inlet conveyor of the packaging apparatus is provided orthogonally to the conveyor conveyor of the tray. It has a great practical value such that it can be reliably positioned in a desired posture by applying it to an existing arrangement.
