Description

Bagged shaping machine

Technical Field

The utility model belongs to the field of bagged goods shaping equipment, and particularly relates to a bagged shaping machine.

Background

At present, the vertical warehouse conveying line is widely applied to various warehouse fields, and has the advantages of reducing manual operation, relieving labor intensity, positioning accurately, being rapid and effective and the like, so that the transportation efficiency of goods in and out of a warehouse is greatly improved in the intelligent warehouse management process. On a vertical warehouse conveying line, many cargoes are packed in a bagging mode, and then the bagged cargoes are placed on a tray and conveyed through the conveying line. In the process of transporting the bagged goods, the position of the bagged goods is easy to deviate due to the fact that an operator codes the bagged goods on a tray, or the bagged goods are easy to loose and incline due to the fact that the bagged goods are easy to loose when transported on a vertical warehouse conveying line. These factors can shift the shape of the bag or the position on the pallet, which can be detrimental to subsequent boxing operations. Therefore, when the bagged goods are transported, the bagged goods are required to be shaped firstly, and then the shaped bagged goods are transported to a boxing position for boxing.

The existing shaping machine generally carries out horizontal pushing on the pushing plate through the air cylinder, so that the pushing plate can shape the left side and the right side of bagged goods entering the shaping machine. The adoption of pneumatic sources requires an additional air source device, which leads to complex structure of the whole shaping machine and increases the cost of constructing a warehouse-setting conveying line. In addition, when the air cylinder is adopted for driving, the pushing distance and the pushing force of the air cylinder are not well controlled, so that bagged goods are easy to cause that the shaping effect is not obvious in the shaping machine, and the goods and the tray are not damaged due to excessive shaping. When the pushing plates are pushed by the air cylinders to reshape the bagged side edges, the pushing plates on the two sides of the bag are mutually independent in movement, so that the two air cylinders are required to be controlled to move in the reshaping process, and reshaping operation of the bagged goods is realized by the two pushing plates. And the shaping force of the push plates on the two sides to the bagged goods is inconsistent easily caused by the operation, so that the shaping effect of the shaping machine is affected.

In the present embodiment, the longitudinal direction of the lower frame 12 is the X axis, the width direction of the lower frame 12 is the Z axis, and the height direction of the lower frame 12 is the Y axis. The conveyor belt 2 is penetrated out along the Z-axis direction, and the conveyor belt 2 is positioned above the lower frame 12. The tray is installed on the conveyer belt 2, and the tray is used for placing the bagged goods 5, and the conveyer belt 2 is used for conveying the bagged goods 5 from the previous process to the frame, and carrying out shaping operation in the frame, and then conveying the shaped bagged goods 5 to the next process.

Referring to fig. 2 and 3, two pushing plates 3 are vertically disposed between the upper frame 11 and the lower frame 12 along the Y-axis direction, and the two pushing plates 3 are symmetrically disposed on two sides of the conveyor belt 2 along the transporting direction. Each push plate 3 is provided with at least one pushing piece 31, the pushing pieces 31 are slidably arranged on the frame, and the driving mechanism is connected with the pushing pieces 31. In actual operation, when the bagged goods 5 on the pallet are transported into the frame by the conveyor belt 2, the conveyor belt 2 stops working. The driving mechanism drives the pushing plate 3 to move towards the bagged goods 5 through the pushing piece 31, so that the pushing plate 3 can reshape the left side and the right side of the bagged goods 5, and reshaping of the bagged goods 5 on the tray is completed.

Referring to fig. 3 to 5, the driving mechanism includes a driving member 41 and a first chain assembly 42, the first chain assembly 42 is mounted on the lower frame 12, and the first chain assembly 42 is located below the pushing member 31. The first chain assembly 42 includes two first timing pulleys 421 and a timing belt drivingly connected to the two first timing pulleys 421. The two synchronous pulleys 421 are arranged in parallel along the X axis, the two synchronous pulleys 421 are respectively arranged at two sides of the conveyor belt 2, and the driving member 41 is connected with one of the synchronous pulleys 421.
