Detailed Description

The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The use of "vertical," "horizontal," "left," "right," and similar expressions are for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, the empty box removing apparatus according to a preferred embodiment of the present utility model includes a conveyor 1 and a first air conveying device 2 provided on the top of the conveyor 1. The first air conveying device 2 is used for continuously generating air flow along the lateral direction of the conveyor 1, and the air force of the first air conveying device 2 is between the air force capable of displacing the empty boxes and the air force incapable of displacing the finished boxes 7, so that the first air conveying device 2 can primarily reject the empty boxes from the conveyor 1, and the empty boxes are prevented from being continuously conveyed on the conveyor 1; in this way, the cassettes which remain on the conveyor belt of the conveyor 1 after being screened by the first pneumatic conveying means 2 are all finished cassettes 7, thus preventing empty cassettes from being sold as finished products. It is obvious that the separation is mainly performed by utilizing the difference in gravity between the empty box and the finished box 7, i.e. based on the difference in friction caused by the difference in gravity.

Preferably, the empty box removing device further comprises a second pneumatic conveying device 3 arranged on the conveyor 1, wherein the second pneumatic conveying device 3 has a larger pneumatic force than the first pneumatic conveying device 2, and the second pneumatic conveying device 3 is used for instantaneously generating an air flow to remove the empty box from the conveyor 1. It will be appreciated that by adding the second pneumatic conveying apparatus 3, the pneumatic force of the first pneumatic conveying apparatus 2 may be adjusted more flexibly, for example, the first pneumatic conveying apparatus 2 only needs to move empty boxes to an offset, so that the process of removing empty boxes by the second pneumatic conveying apparatus 3 does not affect other finished boxes 7 on the conveying belt of the conveyor 1, which are being conveyed normally. Moreover, the further the distance is, the more obvious the pneumatic drop is, so the relay is carried out by the second pneumatic conveying device 3, and the debugging difficulty of the first pneumatic conveying device 2 can be greatly reduced. It should be noted that, if the first pneumatic conveying apparatus 2 may be a single air pipe before the second pneumatic conveying apparatus 3 is not added, it is preferable that a plurality of air pipes are arranged in a ladder manner along the direction in which the empty boxes are removed, so as to ensure that the driving force to the empty boxes is not reduced.

Preferably, the first pneumatic conveying means 2 and the second pneumatic conveying means 3 are both blowing means or are both suction means. In actual products, the blowing device is smoother to use. And as an alternative embodiment, one of the two may be an air suction device and the other may be an air blowing device.

Preferably, the second pneumatic conveying apparatus 3 is arranged overlapping the first pneumatic conveying apparatus 2 in the direction of gravity, and the gas flow direction of the first pneumatic conveying apparatus 2 is the same as the gas flow direction of the second pneumatic conveying apparatus 3. So set up, as long as the first pneumatic conveying apparatus 2 blows the empty box, the second pneumatic conveying apparatus 3 will not miss the action time when restarting at this time, and the empty box is driven to move a certain distance based on the first pneumatic conveying apparatus 2, thus being more beneficial to the empty box being removed rapidly. It will be appreciated that as an alternative arrangement, the second pneumatic conveying means 3 may be arranged on the opposite side of the first pneumatic conveying means 2 and that the direction of blowing or suction of the second pneumatic conveying means 3 may be parallel or perpendicular with respect to the first pneumatic conveying means 2.

More preferably, the second pneumatic conveyor 3 is located below the first pneumatic conveyor 2. The arrangement is based on the fact that the second pneumatic conveying device 3 is high in pneumatic force, and the air box is instantaneously blown off due to the fact that the air generated by the second pneumatic conveying device 3 is in contact with the bottom of the air box.

More preferably, the conveyor 1 is provided with an object detection sensor 4, the object detection sensor 4 is in signal connection with the second pneumatic conveying device 3, and the object detection sensor 4 is used for detecting an empty box which is displaced under the action of the first pneumatic conveying device 2 so as to trigger the second pneumatic conveying device 3 to instantaneously generate air flow. Obviously, this is so arranged that it is not necessary to arrange for a worker to operate the second pneumatic conveying means 3.

Preferably, the object detection sensor 4 is an infrared sensor or other existing contact sensor or the like.

More preferably, the two opposite sides of the conveyor 1 are provided with object stages 5, the object stages 5 are flush with the conveyor belt of the conveyor 1, and the extending direction of the object stages 5 is the same as the conveying direction of the conveyor 1; so arranged, the stage 5 can accommodate the semi-finished product so as to reduce the movement amplitude of the worker to reduce the labor amount. Moreover, the first pneumatic conveying device 2, the second pneumatic conveying device 3 and the object detection sensor 4 are supported by the object stage 5.

Preferably, the conveyor 1 is also provided with a guide bar 6 located directly above the conveyor belt of the conveyor 1. This is arranged so that the cassettes are positioned by means of the guide bars 6 so that the worker can quickly bring the cassettes into position on the conveyor 1 to ensure that each cassette is more closely pneumatically supported by the first pneumatic conveying means 2. More preferably, the extending direction of the guide bar 6 is set at a non-zero acute angle to the conveying direction of the conveyor 1, so that when the hand speed of the worker is too fast and deviations occur, i.e. the box may be a small distance from the guide bar 6, the box will slowly abut against the guide bar 6 as it is conveyed on the conveyor 1, so that the distance between each box leaving the guide bar 6 and the first pneumatic conveying device 2 is the same, i.e. each box is subjected to a uniform detection condition.

The specific working principle is as follows: the cassettes (including the finished cassette 7 and the empty cassette) are transported on the conveyor 1, are attached to the guide bar 6 to be guided by the guide bar 6, and after leaving the guide bar 6, pass through the first pneumatic conveying device 2, if the finished cassette 7 is based on the gravity, so that the cassettes cannot be blown; the empty box is blown and the object detection sensor 4 is blocked, so that the second pneumatic conveying device 3 is started instantly to blow the empty box off the conveyor 1.

The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
