Description

[Detailed Description of the Invention] Technical Field of the Invention This invention relates to a packaged material discharging device for a packaging machine used together with an automatic weighing and value labeling machine.

Technical background of the invention and its problems Conventionally, as shown in FIGS. 1 and 2, in a packaging machine, a heat conveyor 2 having a heating element 1 on its discharge side, and a tray 3 sent out from the heat conveyor 2. Some are equipped with a discharge roller 4 for conveying. In such a device, the distance between the heat conveyor 2 and the discharge roller 4 is set to be large. This is because the belt 5 of the heat conveyor 2 is made of glass fiber, which is heat resistant although it has the disadvantage of being weak against bending.In order to compensate for this property of being weak against bending, the conveyor pulley 5 of the heat conveyor 2 is formed to have a large diameter. This is due to the fact that The occurrence of a dent between the heat conveyor 2 and the discharge roller 4 and the swinging of the conveyed tray 3 is not a serious problem in the packaging machine itself, but as shown in FIGS. 3 and 4. As shown in FIG. 2, a problem arises when an automatic weighing value system 7 is provided at the rear of the discharge side of the packaging machine. In other words, the tray 3 may float up between the heat conveyor 2 and the discharge roller 4, which may cause a shock when it is transferred onto the weighing conveyor of the automatic weighing and value tagging machine 7. This may cause the weighing data to flicker and make it impossible to obtain a normal weighing value, causing the automatic weighing machine 7
It is difficult to make it work properly.

Purpose of the invention The object of this invention is to obtain a packaged object discharging device that can transport the packaged objects in a stable state to an automatic weighing and value tagging machine.

Summary of the invention In this invention, a passing roller body is provided between the conveyor and the discharge roller, which prevents the lifting of the packaged items that may occur between them. It is possible to convey the packaged items in a stable state without giving impact to the weighing conveyor of Since both ends of the support are formed with a shaft that contacts the inner surface of the frame, there is no need for a hole to attach the spanning roller body to the packaging machine, and the spanning roller body can be set simply by placing it there. It is designed so that existing packaging machines can be used as is.

Embodiment of the invention An embodiment of the invention will be described based on FIGS. 5 to 10. First, a packaging machine 11 having a control box 10 is provided. A heat conveyor 12 serving as a conveyor is provided on the discharge side of the packaging machine 11. The heat conveyor 12 includes a large-diameter conveyor pulley 13, a belt 14 made of glass fiber as a main material and suspended on the conveyor pulley 13, a conveyor tension adjustment spring 15, and a belt 14 around a tray 16, which is the object to be packaged. It consists of a heating element 18 that heats and welds the stretch film 17. Further, a frame 19 is formed on the discharge side of the packaging machine 11. A discharge roller 20 is rotatably attached to this frame 19. A round belt 21 is suspended between the discharge roller 20 and the conveyor pulley 13.

A spanning roller body 22 is detachably provided between the heat conveyor 12 and the discharge roller 20. This spanning roller body 22 is
The conveyor pulley 13 and the discharge roller 20
A pair of left and right rollers 23 that contact the conveyor pulley 13 and the discharge roller 20, and an idling roller 24 that does not contact the conveyor pulley 13 and the discharge roller 20 and has a smaller diameter than the roller 23, and the roller 23 are fixedly fitted to provide shaft support. At the same time, the idling roller 24 is positioned between the rollers 23 and is rotatably supported by a shaft 26 via a bush 25, and an E-ring 27 is fitted to the shaft 26 on both sides of the roller 23. It is what it is. The shaft 26 is formed to have a length that substantially matches the spacing between the opposing surfaces of the frame 19, and is provided such that both ends of the shaft 26 oppose and abut against the inner surface of the frame 19.

Next, an automatic weighing and value tagging machine 28 is provided at the rear of the discharge side of the packaging machine 11. This automatic weighing and price tagging machine 28 includes a weighing conveyor 29 connected to the discharge roller 20 and an automatic width shifting conveyor 30.
, a pasting conveyor 31, and a discharge roller controller 32 are installed in this order along the conveyance direction. Also,
A printer 35 having an arm 34 for affixing a label 33 to the stretch film 17 on the affixing conveyor 31 is attached to such an automatic weight labeling machine 28 .

In such a configuration, the heat conveyor 12
A roller 23 is provided between the discharge roller 20 and the discharge roller 20, and a roller 23 is provided which contacts these rollers and rotates in the opposite direction. An idling roller 24 is positioned between the rollers 23 and loosely fitted to a shaft 26 to which the roller 23 is fitted. Crossing roller body 22
is installed, so even if the tray 16 is evenly packed with food as shown in FIG. 9 or the tray 16 is unevenly packed with food as shown in FIG. can be transported without floating or falling over.
As a result, the tray 16 is smoothly conveyed to the weighing conveyor 29 of the automatic weighing value tagging machine 28 without giving any impact thereto, and accurate weighing is performed. After adjusting the position on the automatic width conveyor 30, the tray 16 is conveyed to the pasting conveyor 31, but since the tray 16 on this pasting conveyor 31 does not fall over and become upside down, the arm 34
Labels 33 are affixed to predetermined positions on the stretch film 17 around the tray 16. Then, such a tray 16 finally goes down the discharge roller controller 32.

In this way, the tray 16 is attached to the automatic weighing machine 28.
Even when the machine is in use, it is transported in a stable state without being subjected to shock or being turned upside down.

The tray 16 presses the upper part of the loosely fitted idle roller 24 to rotate it forward, and a bush 2 is provided between the idle roller 24 and the shaft 26.
5 is provided and the idling roller 24 rotates smoothly, so that the tray 16 is smoothly conveyed by the spanning roller body 22.

Further, the spanning roller body 22 can be connected to the heat conveyor 12 and the discharge roller 20 by simply placing both ends of the shaft 26 in contact with the frame 19 and the roller 23 in contact with the heat conveyor 12 and the discharge roller 20.
Since the wrapping roller body 22 is installed between the wrapping roller body 22 and the wrapping roller body 20, the existing packaging machine 11 can be used as is without the need to form holes or perform additional work to attach the spanning roller body 22 on the packaging machine 11 side. Also, it can be easily attached and detached. In particular, since both ends of the shaft 26 are brought into contact with the frame 19, the spanning roller body 22 can be easily placed in a predetermined position during installation.

In this embodiment, the roller 23 is fitted to the shaft 26 and the idling roller 24 is loosely fitted thereto, but the roller 23 may be loosely fitted to the shaft 26 and the idling roller 24 is fitted thereto.

Effects of the invention As mentioned above, this invention is equipped with a spanning roller body that can be attached by simply placing it between the conveyor and the discharge roller, thereby preventing the lifting and falling of the packaged items that may occur between the conveyor and the discharge roller. As a result, it is possible to transport the packaged items in a stable state without applying impact to the weighing conveyor of the automatic weighing and value marking machine, and also to ensure that the wrapping roller body is not in contact with the conveyor and the discharge roller. It is formed of an idling roller with a smaller diameter than the roller, in which the roller and the packaged object come into contact, and a shaft that supports this roller and the idling roller, and has both ends abutting against the inner surface of the frame that supports the discharge roller, so that it can be hung on the packaging machine side. It is not necessary to provide holes for attaching the transfer roller body, and the existing packaging machine can be used as is, and it has the advantage that it can be easily attached and detached.
