Abstract

PURPOSE:To facilitate reversing a corrugated cardboard box by catching a box with an L-shaped receive frame having a bearing surface for supporting the box and a stop surface for receiving the front side of the box, and turning the receive frame to slide down the box along the stop surface in the above apparatus for a corrugated cardboard box. CONSTITUTION:A box 2 sealed by a sealing machine 11 and transferred on a conveyer 1 is fed into a receive frame 5. When the box is detected by a detector not shown, a detection signal is sent to a sequence circuit, and compressed air is introduced into an air cylinder 19 of an interlocking mechanism 8 through a solenoid valve, whereby a piston rod is contracted to turn a shaft 6 through a rack 18 and a pinion 17 and turn the receive frame 5 in transfer direction as indicated by a two-dot chain line. Thus, the box 2 is slided down (b) along the stop surface 4. The lower corner portion of the box 2 in the slide- down direction is brought into collision with a lower side roller conveyer 20, so that the box 2 is further turned round a supporting point by inertia to be completely reversed and conveyed. Thus, automation of reversing the box can be accomplished.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a box-like object reversing and transferring device that turns over an object packaged in a box such as a corrugated pole box while transferring it. It can be used as a reversing transfer device for fruit plants, etc.

Problems to be solved by the invention For example, in a persimmon fruit sorting plant, the sorting machine is used to classify different grades according to quality,
Fruits sorted into different grades (size and weight) are hand-packed into several tiers in corrugated pole boxes, but when packing a fixed number of fruits by grade in a flat layer in close contact, the stem part with the peduncles is It is easier to pack the fruit with the side facing up, but in order for consumers to open the lid of the box and check the quality during the distribution process after the market, it is better to place the stem on the bottom so that the butt side of the fruit can be seen. For this reason, judging from the designs, letters, etc. printed on the outside of the cardboard box, the top side of the box is first stapled or glued in the box making machine, and the box is turned upside down. After filling the box with fruit, the top, which should become the bottom, is sealed with a needle or glue using a sealing machine, and then the box is turned over by hand so that the pattern, letters, etc. can be seen normally. If so, the work is not easy.

Means for Solving the Problem The present invention has a receiving surface (3) for receiving a box-shaped object (2) transferred by the upper conveyor (1) and a stop surface (4) for receiving the front side surface. The receiving frame (5) to be formed is placed on the conveyor (
1) Detection of the transported object (2) by a detection device (7) equipped with a shaft (6) rotatable back and forth on the upper surface and detecting reception of the transported object (2) into the receiving frame (5). It is characterized by providing an interlocking mechanism (8) for rotating this receiving frame (5) in relation to the rotating receiving frame (5), and by sliding on the front surface (4) of the rotated receiving frame (5) and inverting it to the lower side. The structure of the box-shaped object reversal transfer device is as follows.

Functions and Effects of the Invention When a box-shaped object (2) transferred by the conveyor (1) on the upper side of the transfer is sent into the receiving frame (5), the receiving surface (3) of the receiving frame (5) 2) is taken over from the conveyor (2) and guided into the receiving frame (5), and the front side (4) receives the end side of the conveyed object (2) in the transfer direction i. At this time, the detection device t (7) detects the acceptance of the object to be transported, and when the interlocking mechanism (8) is activated due to this detection, the receiving frame (5) moves the single shaft (6) with the object on it. With the top surface of the conveyor (1) as the center, the front side that receives the conveyed object (2) as the zero rotation progresses, rotating from the upper side to the lower side of the conveyor, gradually supports the weight of the conveyed object. , when the conveyed object (2) gradually slopes downward beyond the horizontal state and stops after being appropriately sloped, or just before that, the conveyed object (2) reaches the stop surface whose front surface is sloped at the time of receiving it into the receiving frame (5). It slides upward, and after the lower corner in the sliding direction collides with the receiving surface of a conveyor or the like on the lower side, the receiving frame (5) is reversely transferred by the inertia of the sliding movement with the upper surface at the time of reception facing downward.

In this way, according to this configuration, there is no need to fix the object to be transported on the receiving frame (5), and the object to be transported (2) is reversed using natural force at the rotationally linked end of the receiving frame (5). Therefore, reversal transfer can be performed smoothly and the structure can be simplified.

Embodiment In the example shown in Figure 1, the box-shaped conveyed object (2) is a cardboard box filled with fruit, and the conveyor (1) is opened while transporting an upside-down cardboard box filled with fruit. After folding the flap (9) on the upper side of the corrugated pole box to close it, the inner conveyor is inserted into the sealing machine (11), which seals the flap (9) by punching it with an air boxer (10). A roller conveyor (1) is connected to the lower side of the transfer direction (A).The conveyor (1) is connected to a rotatable roller (12) in a pivotal manner.

The receiving frame (5) has a shaft (6

This receiving frame (5), which has one surface (4) and is fixed to the shaft (6), is rotatably attached to the left and right shaft (6) receiving portion of the frame holder (16).
) are equipped.

The detection device (7) is a light emitting/receiving type phototube that receives reflected light that is reflected by the box from the side when the transported object (2) is received in the receiving frame (5).

The interlocking mechanism (8) includes a rack (18) that meshes with a binion (17) provided at one end of the shaft (6) of the receiving frame (5), and connects one end of this rack (1B) to the frame holder (1B). It is connected to the piston rod of the air cylinder (18) installed in a horizontal position, and when the phototube of the detection device (7) detects the conveyed object (2), the solenoid valve is activated to activate the air cylinder (18). fibrillate the piston rod,
When the rack (18) rotates the shaft (6) on which the pinion (17) is provided, the receiving frame (5) rotates upward, and the front surface (4) of the receiving frame (5) is kept constant on the downstream side in the transfer direction. After stopping the rotation of the receiving frame (5) when reaching the inclination angle, the conveyed object slides on the stop surface (4) and after an appropriate period of time has elapsed, the solenoid valve is activated and the receiving frame (5) is moved in the opposite direction. A sequence control circuit is configured to rotate the conveyed object (2) and return it to the conveyed object (2) receiving position. The air cylinder (19) is supplied with compressed air from the near compressor.

A roller conveyor (20) is provided on the lower side of the receiving frame (5) to further transfer the objects (2). The transfer start end (21) t* of this roller conveyor (20) is positioned lower than the tip of the stop arm (14) of the receiving frame (5) when the roller conveyor (20) is in an inclined position, so that the conveyed object (2) is placed on the stop surface (4). the lower corner of the roller conveyor (2)'
20) After colliding with the top surface and stopping, the box is placed in the receiving frame (5) on the roller conveyor (20) by inertia so that the box is turned upside down with the top surface facing downward when received.
