Description

 Double-channel stacking system for boxing machine

 The invention relates to a stacking machine stacking mechanism, in particular to a boxing machine double channel stacking system. Background technique

 The cartoning machine is a kind of equipment for semi-automatic or automatic loading of unpackaged products or small-package products into transport packaging. The working principle is to load the products into the box according to a certain arrangement and quantity (≤fi carton, plastic) Box, tray), and close or seal the opening of the box. In the automatic packaging assembly line, it is the core of the whole line system operation, and its working efficiency directly affects the efficiency of the entire assembly line.

 At present, the stacking mechanism of the boxing machine at home and abroad is a single-chamber stack, which includes a pair of stacked ribs, and a stack of bottom brackets with a return spring is disposed at a lower portion of the stack ribs, and a center below the stack ribs Set a top lift plate. The working principle is as follows: After the product is input, after the position is detected by the electric eye, the jacking plate is pushed up into the stacking area, and the bottom supporting block of the stack is retracted under the force of the force. After the product is in place, the jacking plate is lowered. The bottom support block of the stack is rebounded by the restoring force of the spring, and the product is placed on the bottom support block of the stack.

 The disadvantages of this mechanism are: Since the jacking plate is raised up to slightly higher than the bottom bracket of the stack, and the product is suitable for different heights, the height of the bottom bracket of the stack is higher. Thus, for thinner products, the jacking plate must be raised to this height each time, which inevitably prolongs the time of a single stack, affecting the packing speed of the product, which in turn limits the speed of the previous line.

 The working principle is as follows:

 Principle of baffle width adjustment:

 Rotating the adjusting handle A44 to drive the nut of the screw nut pair A41 to rotate, so that the screw of the screw nut pair A41 drives the second baffle to move to the first baffle in the horizontal direction under the constraining guidance of the guide bushing sleeve assembly A42. And further adjusting the width between the second baffle and the first baffle.

 Feed limit adjustment principle;

The screw is driven by rotating the adjustment handle B56, and then by adjusting the transmission rod 55 and the bevel gear assembly 54. When the B53 rotates, the slider B52 moves in the extending direction of the feeding guide 23 by the guide post B51, thereby changing the distance from the front end of the feeding guide 23, thereby realizing the position adjustment of the articles on the feeding guide 23.

 Lifting position adjustment principle:

 By rotating the adjustment handle C63, the lead screw driving nut of the screw nut pair C62 and the jacking mounting plate 31 are moved in the horizontal direction under the guidance of the horizontal linear guide C61, so that the jacking plate 32 on the jacking mounting plate 31 continues to be maintained. At the center of the first flap 21 and the second flap 22.

 The overall working principle:

 As shown in Fig. 9, when the large product P1 is produced, the intermediate buffer mechanism is not required, so the intermediate action cylinder acts and compresses the return spring, so that the product P1 directly passes through the buffer tray, and the intermediate buffer mechanism does not function.

 When the P1 product is in place, the jacking action is pushed to push the P1 product to the main pallet. When the P1 product contacts the main pallet, the upward pressing force pushes the main pallet, and the main pallet compresses the return spring, around The upper fixing pin is oscillated. When the P1 product passes the main pallet, the spring returns to the elastic force, and the jacking plate is lowered. The P1 product is placed at the main pallet, and then the cycle is actuated to realize the stacking of three P1 products.

 As shown in Fig. 10, when the small-sized P2 is produced, the intermediate buffer mechanism needs to be operated, and the intermediate-acting cylinder does not operate, and the cushioning plate is extended by the elastic force of the return spring.

 When the P2 product is in place, the jacking action is pushed to push the P2 product to the buffer tray. When the P2 product contacts the buffer tray, the upward pressing force pushes the buffer tray, and the buffer tray compresses the spring, and is fixed around the small plate. The pin is oscillated. When the P2 product passes the buffer plate, the spring returns to the elastic force, and the jacking plate is lowered. The P2 product is placed at the buffer plate, and then the cycle action is performed to realize the stacking of four P2 products. As a middle transition, since the distance of S2 can only be placed on a stack of four P2 products, the top pusher pushes up the four P2 products to the main pallet before stacking the fifth P2 product. Then, repeat the previous action to achieve a stack of six P2 products.

 Stacking time comparison:

 P1 P2 product, P1 code 3 layers, P2 code 6 layers, stroke S, intermediate buffer position S1=2/5S, push plate movement speed: V;

 P1: Time of palletizing: 2S/V=T, total time: 3*(2S/V)=6S/V

 P2: 2S 1/V+2S 1/V+2S 1/V+2S/V+2S 1/V+ 2S/V=8S 1/V+4S/V

 When: S 1=1/4S, the time of the product of the 3-layer PI is the same as the time of the product of the P2 of the 6-layer code, which is 6S/V. This will not affect the packing speed of the product. If S 1/4S, the time of P6 is less than the time of P3.

 However, if the intermediate transition buffer is not used, the time for the 6-layer P2 product is: 6* (2S/V)

=12S/V. is much larger than the stacking time of P1 products 6S/V, which will affect the speed of the entire box.
