Abstract

PURPOSE:To prevent an impact from being applied to a product at the time of standing by providing a horizontal conveyer, side grip conveyers, an opening/ closing device for opening/closing an entrance of the side grip conveyer and a product sensor. CONSTITUTION:A product 1 in a carton flowing on a horizontal conveyer 2 in a laterally laid state enters between side grip conveyers 5 wherein grip force has been adjusted so that a pair of standing products in an opened state can rotate. The carton is sensed by a grip position sensor 11, an opening/closing device 9 is closed by this signal to cause the side grip conveyers 5 to grip both sides of a rear part of the carton 1, and the rear part of the carton 1 is lifted while the product 1 and the side grip conveyers 5 are rotated toward an ascending slope at a faster speed than the horizontal conveyer 2. At a position where the carton 1 can stand up by its own weight on a slope, it is sensed by a standing position sensor 12, and the opening/closing device 9 is opened by this signal to release the carton 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product standing device for automatically standing products on a conveyor in a packaging line.

[0002]

2. Description of the Related Art Conventionally, for example, in order to stand up a product packed in cartons on a conveyor, as shown in FIG. 5, two horizontal feed conveyors 01 and 02 are continuously arranged with a step and are placed on the upstream conveyor 01. Conveyor 0 for carton-stuffed products 03 sent horizontally with the bottom surface to be erected in front
An apparatus that naturally stands up on the downstream conveyor 02 using the tip of No. 1 is generally used.

[0003]

In the above-mentioned conventional apparatus, since the drop of the two conveyors 01 and 02 is used, the product contents may be damaged by shock.
In addition, the landing after reversal is unstable, and falls easily occur. Further, there is a problem that the product cannot be stood up when the space between the products 03 supplied on the conveyors 01 and 02 becomes too narrow.

The present invention is directed to such problems with the purpose of making it possible to stand up surely without giving a shock to the product at the time of standing up, and to make it possible to stand up even when products are connected. Was done.

[0005]

In order to achieve this object, according to the present invention, a horizontal conveyor for moving a product with its bottom surface to be erected forward and a feeding direction facing both sides of the horizontal conveyor. And a pair of side grip conveyors with adjustable gripping force so that the product can be operated at a higher speed than a horizontal conveyor and can be rotated upright while gripping both sides of the product rear side and lifting in the feeding direction. A device for opening and closing the entrance side of the side grip conveyor, and a product detection device provided to detect a product that has entered between the side grip conveyors and an upright product for controlling the opening and closing of the opening and closing device. It is characterized by

[0006]

By means of the above means, the carton-stuffed products that flow horizontally on the horizontal conveyor are adjusted in gripping force so that the products can rotate when the pair of products in the opened state stand upright. When you enter,
Detected by the product detection device for detecting the grip position at the entrance, this signal causes the opening / closing device to close and move the entrance side of the side grip conveyor in the closing direction, and the side grip conveyor contacts both sides of the rear part of the carton. As a result, a friction holding force acts, gripping the both sides of the rear part of the carton and climbing at a speed faster than the horizontal conveyor, and lifting the rear part of the carton while rotating between the product and the side grip conveyor.

While the side grip conveyor is operating in this state, the succeeding products on the horizontal conveyor are blocked by the carton restraining guide on the entrance side conveyor frame of the side grip conveyor and held on the horizontal conveyor. The product in this state is detected by the product upright position detection device at the position where the carton is in an attitude that allows the carton to stand up under its own weight due to the side grip conveyor, and this signal opens the opening / closing device to activate the entrance of the side grip conveyor. The side space is opened, the standing carton is released, the next product is returned to a state where it can be received, and the next carton-stuffed product is received between the side grip conveyors.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an overall side view of a standing device according to an embodiment of the present invention. In FIG. 1, 1 is a carton-filled product in which products such as bolts are placed in a carton, 2 is a horizontal conveyor 2 that conveys the carton-filled product 1 from the left to the right in the figure with the bottom surface on which the product 1 is to be raised facing forward, and 3 is a horizontal conveyor 2 Frame, 4 is a carton guide on the horizontal conveyor frame 3, 5
Is located on both sides of the horizontal conveyor and climbs in the feeding direction and is inclined at a higher speed than the horizontal conveyor, and grips both sides of the product rear side so that the product can stand and rotate while lifting in the feeding direction. Is a pair of side grip conveyors, and 6 is a mounting frame for the side grip conveyor 5.

Further, 7 is a support base for movably supporting a lower end side (hereinafter referred to as an inlet side) of the side grip conveyor 5 mounting frame 6 provided on the horizontal conveyor base 3, and 8 is a horizontal conveyor. The side grip conveyor 5 provided on the frame 3 across the horizontal conveyor 2
A support base for rotatably supporting the upper end side of the mounting frame 6 for use, and 9 is an opening / closing device for driving by opening the entrance side of the side grip conveyor 5 on the support base 7 at a constant interval width.

Further, 10 is a tension holding device for the side grip conveyor 5, 11 is a light wave transmission type detection device for detecting the grip position of the carton-stuffed product 1 fixedly arranged on the horizontal conveyor frame 3, and 12 is a horizontal conveyor. A detection device of a light wave transmission type or the like for detecting the position where the carton-stuffed product 1 fixedly placed on the pedestal 3 can stand up (separated position), 13
Is a drive motor for the side grip conveyor 5 provided on the upper end side of the mounting frame 6.

FIG. 2 is a side view of the side grip conveyor 5 taken along line II-II of FIG.
FIG. 3 is a plan view showing a state in which the side grip conveyor is in frictional contact with a, and FIG. 3 is a state in which the side grip conveyor 5 is rotated in the ascending direction from the state of FIG.
