Abstract

PURPOSE:To carry material under a constant condition by carrying a material to be carried having a projection in one side thereof on two parallel belts pro vided between guides, and placing the material so that the projecting side is placed on a belt of which speed is higher, and slipping the projection by a diference in speed between the two belts, in contact with the guide for carrying. CONSTITUTION:Two parallel belts (a), (b) are made to travel between guides (c), (d), and the travelling speed of the belt (b) is a little higher than that of the belt (a). A projecting piece 4 is provided in one side of cover 3 of a filled container A, and the filled container A is made to travel on the belt (a), (b) so that the projecting piece 4 side is placed on the belt (b) side. Consequently, the projecting piece 4 side of the container A is slipped in contact with the guide (d) to be slid by a difference in speed between both the belts (a), (b). Consequently, the container A is made to travel under the condition that the travelling direction is constant, and a trouble in the next work process is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention belongs to the field of distribution, and specifically relates to a method for transporting objects in a constant direction.

(Prior Art) Generally, in a device that conveys an object using two parallel belts, the parallel belts usually move at a constant speed.

(Problem to be solved by the invention) In the case where the parallel belt has a constant velocity as described above,
For example, if the direction of the conveyed object changes due to the feeding state of the conveyed object onto the belt or the slack of the belt due to the weight of the conveyed object, the conveyed object will be conveyed in that state. In the case of a tilted state, maintaining the tilted state may cause problems in subsequent work processing.

The present invention has been made in view of these points, and it is possible to always convey the conveyed object in a constant direction by simply adding a simple means to the parallel belt, and to effectively deal with subsequent work processing. This is the purpose.

(Means for Solving the Problem) In order to achieve the above object, in the present invention, the speed of one of the two parallel belts between the guides is made slightly higher than that of the other. , trying to solve the problem.

That is, in the present invention, a conveyed object having protrusions on the sides in plan view is placed on two parallel belts, one of which has a slightly higher speed, with the side having the protrusions on the heald side having a higher speed. When the belt is placed and transported, the slip that occurs between the belt and the belt due to the speed difference on the faster belt side,
A method is adopted in which the protrusion is in sliding contact with the guide and is conveyed in a constant state.

(Example) Hereinafter, an apparatus for implementing the method of the present invention will be described based on the drawings.

In Figure 1, two parallel belts (a) and (b)
Even if it is between the guides (c) and (d) on both sides, it is stretched between the pulleys (e) and (f) driven by the motor (m) and the tension pulleys (g) and (h). ing.

For example, the drive pulley has a circumference of 40 m/m relative to a circumference of pulley (e) of 390 m/m, so that the speed of pulley (f) is slightly (about 4%) higher than that of pulley (e).
5m/m.

A guide + counter (1) is provided above between the two bells h (a) and (b).

The conveyed object is, for example, a sealed plastic container (A) filled with butter, cheese, cream, jam, etc. In plan view, the short side of the rectangular long piece is opposite to the straight part (1) side. It has an arcuate part (2) (2) on the outside, and the lid (3) has a protruding tab (4) near the end of the arcuate part (2), and a protruding tab (4) on the same side. A bulge (5) for protruding the handle of the knife is provided on the side thereof, and a groove (6) for opening and closing the lid (3) is provided on the opposite side.

A filled and sealed container (A), which is an object to be conveyed, is conveyed between two parallel bells (a) and (b) and a guide plate (i).

In Figure 1, if the filled and sealed container (A) is at the position of the imaginary line, the container (A) placed on it will move due to the movement of both belts (a) and (b), but the belt) (b) Since the speed on this side is high, this side advances further and the protruding tab (4) of the lid (3) comes into contact with the guide (d).

In this state, the heald (b
) side, a slip occurs between the container (A) and the container (A).
This slotted knob causes the protruding tab (4) to advance while slidingly contacting the guide (d).

The container (A) always moves in a stable state in which its direction is, for example, the straight portion (1) side of the container (A) perpendicular to the direction of the belts (a) and (b).

In this way, the advanced container (A) is located at Bell 1-(a)
and outside (b), although not shown,
For example, it is pushed out in the lateral direction by a lateral pushing means and is stored in a section of the conveyor belt for the next process. The guide plate (i) prevents the container (A) from moving when the container (A) is being transported.
Guide from above to feed stably so that it does not float up.

Such a conveying device is interposed between the front process and the rear process, and the container (A) is sent out from the front process onto the bells (a) and (b), and in the conveyance process in this part. ,
Since the items are arranged in a certain direction, there is no need to make the conveyance process as long as the one on the left.

The one shown in Fig. 2 is before the improvement shown in Fig. 1, and its configuration consists of two parallel healds (a゛) and (
b゛) is located between guides (C゛) and (d゛) on both sides, and is connected to pulleys (e゛) and (f゛) driven by a motor (m゛), and tension pulleys (g゛) and (h).゛).

Since the driving pulleys (e') and (f') have the same diameter, the belts t-(a') and (b') have constant speed.

This point is explained by the improved belt (a) shown in Fig. 1.
This is different from the case where the speed of belt (b) is slightly increased.

Therefore, the plastic filled and sealed container (A
′) is placed obliquely on two parallel belts (C゛) and (d′), since both belts (a”) and (b゛) are at the same speed, the arcuate portions on both sides (2°) and (2゛) are conveyed in a state slightly apart from the guides (C゛) and (d''), and from this oblique direction they are pushed out to the side in the next process. This will cause trouble in some cases.

(Effects of the Invention) In the conveying method of the present invention, when conveying an object having a protrusion on the side in a plan view, the protrusion side is installed between both guides, and the speed of one side is slightly higher than the other. By placing books on the heddle side, which has a higher speed, in the conveyor device consisting of parallel belts, the protrusion can be moved with the slip generated between the belt and the bell I by the speed difference between both belts on the higher speed belt side. Since the object is conveyed while sliding on the guide, the conveyed object is adjusted in a fixed direction between the two parallel belt conveyors with different speeds, and when being pushed out to the next process, for example, to the side. Despite the slight improvement, the present invention is particularly effective in conveying objects having protrusions on the sides when viewed from above.
