Semi-automatic box stacking device

Abstract

The invention discloses a semi-automatic box stacking device comprising an upright post, a cross beam, a hoisting motor, a tackle, a steel wire rope and a clamping mechanism. The upright post is vertically arranged, the cross beam and the upright post form a rotating pair, the tackle can slide on the cross beam, the hoisting motor realizes winding and releasing of the steel wire rope by rotating ahoisting drum, the clamping mechanism comprises a left handle, a right handle, a front clamping plate, an inclinometer, a middle sliding plate, a rear clamping plate, a motor and a threaded rod, themiddle sliding plate and the rear clamping plate form a moving pair and can be locked through a screw, the front clamping plate and the middle sliding plate form a rotating pair, a threaded block is connected with the lower end of the steel wire rope, and the motor dynamically adjusts the hanging point position of the steel wire rope according to the inclined state of the front clamping plate detected by the inclinometer in real time, so that the clamping mechanism is always in a balanced state; an electric cylinder enables the rear end of the rear clamping plate to rotate upward, so that theexpansion operation of the clamping mechanism is realized; and the clamping mechanism achieves self-clamping of a box by means of the gravity of materials in the box, such that no additional clampingdrive is required.

Description

Technical field [0001] The invention relates to the field of box stacking, in particular to a semi-automatic box stacking device. Background technique [0002] Box palletizing is a very important link in the production line. The speed and quality of palletizing are directly related to the production efficiency of the production line. The existing box palletizing forms mainly include the following: automatic robot palletizing, semi-automatic suction and lifting Palletizing, manual palletizing, etc.; robot automatic palletizing efficiency is high, which is very suitable for production lines with large production capacity. However, due to the high equipment procurement costs and maintenance costs, a large number of small enterprises cannot afford the funds, and the production capacity of small enterprises is relatively high. There is not much demand for automatic palletizing by robots. Therefore, automatic palletizing by robots is not popular in a large number of small enterprises; ...

[0002] Box palletizing is a very important link in the production line. The speed and quality of palletizing are directly related to the production efficiency of the production line. The existing box palletizing forms mainly include the following types: robot automatic palletizing, semi-automatic suction lifting Palletizing, manual palletizing, etc.; automatic palletizing by robots is highly efficient, and is very suitable for production lines with large production capacity. Therefore, the automatic palletizing method of robots is not popular in a large number of small enterprises; semi-automatic suction palletizing is suitable for various types of materials such as plates, bagged materials, and boxed materials. Materials, especially in the field of plates, are widely used, but the form of suction lifting requires the use of suction cups and vacuum generators to generate negative pressure to suck materials, and suction cups are vulnerable parts, which are airtight after a period of use decline, a new suction cup must be replaced, and the equipment that generates vacuum also needs to consume energy continuously, which increases the cost of equipment use, and is also limited by the weight of the material when lifting the material packed in the carton, because the suction lifting device can only absorb the carton The upper cover, when the material is heavy, will tear the upper cover of the carton. Therefore, the semi-automatic lifting device cannot be used to lift the carton with heavy material. In addition, because the surface of the wooden box is rough and breathable, the suction lift The suction and lifting effect of the device on wooden packaging boxes is not ideal; at present, a large number of small enterprises mostly use manual palletizing for the palletizing of box packaging materials. Symptoms such as protruding discs, high labor intensity, low technical content, and low wages also lead to large turnover of palletizing workers and difficult recruitment management

[0003] The invention patent with publication number CN105143089A discloses a device for manually guiding load movement, including a stand, a cantilever, and a clamping piece. The vacuum generator provided on the clamping piece generates negative pressure, thereby absorbing the load, and passing the load The rope lifts the load, and the operator moves the load to the target position and then puts it down; this semi-automatic suction lifting palletizing method is suitable for lifting light weight materials, when the cartons contain dense materials such as salt , the top cover of the carton is easy to be torn, which will not only lead to the failure of the suction lifting, but also cause the operator to be injured by the falling heavy objects, causing personal injury and economic loss
